Description

  The present invention relates to a method of processing a portable device and an apparatus therefor.

  Currently, there are many portable devices around us. The "mobile device" in the present specification refers to a device which can be carried and used. The portable device also includes a communication device (terminal) and an information device (terminal). As communication devices, various devices such as multi-functional mobile phones called smartphones and mobile Wi-Fi routers are known, and as information devices, various devices such as tablets and electronic book terminals are known.

  At present, from the viewpoint of securing resources, it is required to recover from the portable device the parts constituting the used portable device. And as said components, the secondary battery used as the motive power source of the said portable apparatus is mentioned, for example. As this secondary battery, for example, a lithium ion battery is widely adopted in portable devices. The lithium ion battery is also referred to as a lithium ion secondary battery, and hereinafter, it is simply referred to as "LIB", and LIB is given as a representative example of the secondary battery.

  Portable devices are miniaturized to be portable and easy to use. On the other hand, higher performance of the portable device is in progress, and power required by the portable device is also increasing. Under such circumstances, LIB is frequently used in the portable device because it can supply relatively high power relative to its size.

  For example, assuming that the LIB is recovered from the portable device, conventionally, the task of recovering the LIB from the portable device has to be performed manually. The cost is rather expensive than manual work.

  In addition, there are many tablet terminals having a built-in secondary battery (for example, LIB) among portable devices. The "tablet terminal" in this specification refers to a terminal which is a plate-like electronic device as the name implies. There are many tablet terminals provided with a touch panel display. "Touch panel display" refers to a display in which a screen is displayed and a touch panel are integrated. When a touch panel display is adopted, it is possible to realize a considerable reduction in size (thinning), and it becomes possible to provide a thin portable device. However, on the other hand, since it becomes thin, it is necessary to reduce the thickness of the LIB as well, and it is formed by inserting a plate-like (square) LIB, and in some cases, an electrolytic solution and an electrode into a resin film. It is necessary to attach a laminated type LIB (also called a battery pack) to a thin portable device. In such a case, there is a high possibility that the LIB body or the battery pack may be accidentally damaged when recovering the LIB from the portable device. That is, the task of recovering LIB from the portable device requires precision, and a highly skilled worker is required. In such a case, it will be difficult to shorten the working time, and the processing cost of the portable device will further increase.

As a means to solve the above-mentioned subject, the present inventor is examining whether the technique (Japanese Patent Application Laid-Open No. 2014-183617) disclosed by the present applicant can not be used based on his / her knowledge. The technique is a technique for recovering a rare earth magnet disposed in a rotor, and is a technique for applying a mild impact to the rotor from the outside to discharge the internal rare earth magnet out of the rotor.
However, when this technology was applied to the above case, although LIB was separated from the portable device, LIB was significantly shattered, and the recovery of LIB could not be satisfactorily performed.

  The present invention proposes a technology for efficiently recovering a secondary battery without relying only on manual work when recovering the secondary battery from a used portable device and suppressing crushing of the secondary battery. To be a subject.

  The present inventors diligently studied to solve the above problems. At this time, the inventor focused on the installation situation of LIB inside the portable device. As a result, the inventor has found that LIB is not firmly fixed inside the portable device, but in some cases, it is fixed to such an extent that the LIB is fixed inside the portable device by the adhesive. On the other hand, in the case where the technology disclosed by the present applicant is applied in this case, it was also found that the impact was excessively and repeatedly applied to the portable device many times, and LIB was broken. From these findings, the inventor has found that the method of “providing a suitable impact at one time” is effective for portable devices when performing processing of recovering LIB from the portable devices. .

Effects of the Embodiment In addition, as to the configuration not described below, a part of known configuration may be adopted. Further, in the present embodiment, the direction of the sky in the vertical direction is referred to as upper, and the direction of the ground is downward.

<1. Processor 1 of portable device α>
First, the processing device of the portable device α in the present embodiment is for separating LIB from the portable device α. The basic configuration of the processing apparatus will be described with reference to FIG. FIG. 1 is a diagram showing an outline of a processing device 1 of a portable device α in the present embodiment.
The processing device 1 of the portable device α in the present embodiment has the following configuration.
・ Processing chamber 2 for processing used portable device α
・ A loading unit 3 for loading the portable device α into the processing chamber 2
The rotating body 4 disposed in the processing chamber 2 and flying the portable device α introduced from the input unit 3
· Scattering portion 5 for scattering the position where the portable device α collides with the rotating body
· A collision unit 6 which is a collision destination of the portable device α blown away by the rotating body 4
Each component will be described in detail below.

1-A) Treatment room 2
The processing chamber 2 in the present embodiment refers to a portion that processes the used portable device α. In the processing chamber 2, a rotating body 4 and a collision part 6 are provided. As a specific structure, in the known apparatus, the configuration of the processing chamber 2 used for processing the used portable device α may be adopted.

1-B) Input 3
The input unit 3 in the present embodiment is a portion for supplying the used portable device α into the processing chamber 2 and may be called a supply unit. As a specific structure, in a known apparatus, a configuration provided to supply used portable device α into the processing chamber 2 may be adopted. In the present embodiment, as shown in FIG. 1, an example in which the insertion port 3 is provided with an insertion port provided with an inclination such that the portable device α slides down into the processing chamber 2 will be described. Of course, a configuration may be provided in which the portable device α is introduced into the processing chamber 2 by a conveyor or the like, or the portable device α is inserted into the processing chamber 2 by dropping it.

  Note that the input unit 3 in the present embodiment is directed toward the portion on the starting point side (hereinafter, also simply referred to as “upstream side”) in the rotation direction of the rotating body 4 among the upper half portion of the rotating body 4. Is placed at a position where it can be thrown. When the portable device α is introduced into the processing chamber 2 from the insertion portion 3, the portable device α slides down to the rotating body 4 which is rotating, and is caught by the projection 42. Then, the portable device α is separated from the protruding portion 42 by the circumferential speed of the rotating body 4 and is blown to the collision portion 6. This operation makes it possible to apply an appropriate impact to the portable device α at one time. Note that the skipping of the portable device α to the collision unit 6 is also referred to as “providing an acceleration to the portable device α”.

  As described above as the findings of the present invention, in a portable device α that is a tablet terminal incorporating a secondary battery (for example, LIB) and provided with a touch panel display, the LIB is not firmly fixed. Therefore, the impact given to the portable device α should not be too large so as not to destroy other parts. On the other hand, in the case where the technology disclosed by the present applicant is applied in this case, if the portable device α is subjected to a large and excessive impact, the LIB itself is broken to cause an electric leakage or ignition. It may be. In order to solve this situation, in the present embodiment, a configuration is adopted in which an appropriate impact is given to the portable device α at one time by flying the portable device α by the rotating body 4 and causing the collision portion 6 to collide. It is adopted.

  In the present specification, “shredding of LIB (and hence crushing of the secondary battery)” refers to a situation where sparks due to ignition, short circuit, and leakage of electrolyte occur as LIB is damaged. In other words, "suppressing LIB fracture" means that each of the above phenomena does not occur, and as long as this state can be maintained, the LIB casing (exterior) There is no problem with some variations in.

  If the portable device α inserted from the input unit 3 is separated due to the flying by the rotating body 4 and the collision with the collision unit 6, the LIB falls downward from the gap (W etc.) described later, and described later LIB is stored in the reservoir of

  On the other hand, even if LIB is not separated from the portable device α due to flying or collision, the portable device α falls downward with the LIB built in, and the portable device α is stored in the storage section described later Therefore, after sorting, the portable device α may be inserted from the input unit 3 onto the rotating body 4 again.

As described above as the findings of the present invention, LIB will be broken if the portable device α is subjected to a large and repeated impact. Therefore, a method of "providing a suitable impact at one time" is effective for the portable device α. In other words, it is ideal for the mobile device α to have only one collision chance. In order to bring this ideal closer to reality, the configuration described in this embodiment is adopted. According to the configuration of the present embodiment, it is possible to apply an appropriate impact at once to most of the input portable devices α.
Although some portable devices α may be returned to the top of the rotating body 4 again and may be re-jumped to the collision part 6, such portable devices α may be limited to a very small number and collide with the rotating body 4 This can be suppressed by adjusting the distance to the portion 6 and the peripheral speed of the rotating body 4.

  In the present specification, “the starting point side (that is, the upstream side) in the rotation direction of the rotating body 4” refers to the portion from the leftmost portion to the uppermost portion of the rotating body 4 shown in FIG. But preferably the vicinity of the leftmost part of the rotating body 4.

  In the present embodiment, the portable device α is preferably supplied to the upstream side in the rotation direction of the rotating body 4. This is because it is possible to cause the collision portion 6 to collide vigorously when the supply is performed upstream.

  In addition, in order to prevent the portable device α processed in the processing chamber 2 from erroneously flowing back from the input unit 3, a partition such as a chain curtain (not shown) is provided in a portion in front of the processing chamber 2 in the input unit 3. It may be provided.

1-C) Rotor 4
The rotating body 4 in the present embodiment is disposed in the processing chamber 2 and is for flying the portable device α inserted from the input unit 3. The rotating body 4 mainly has the following two configurations.
・ Rotor 41 as a basis of the rotating body 4
· Projections 42 protruding from the circumferential surface of the rotor 41

1-C-a) Rotor 41
The rotor 41 in the present embodiment is in the form of a roller that is the basis of the rotating body 4. As a specific structure, in the known apparatus, the configuration of the rotor 41 used for processing the used portable device α may be adopted. A shaft serving as a central axis of the rotor 41 is fixed to the processing chamber 2 and installed.

1-C-b) projection part 42
The protruding portion 42 in the present embodiment is configured to be able to catch the portable device α inserted from the insertion portion 3 when the portable device α contacts the rotating body 4 and to fly the portable device α by the rotation of the rotating body 4. Refers to the portion projecting from the circumferential surface of the rotor 41. As a specific structure, in a known apparatus, one mounted on a rotor 41 for processing a used portable device α (for example, a swing hammer described in Japanese Patent Laid-Open No. 2004-267820) is adopted. I don't care.

  In addition, in order to vigorously fly the portable device α, as shown in FIG. 1, it is preferable that the projecting portion 42 further have a configuration that protrudes in the rotation direction of the rotating body 4.

  Also, the number of protrusions 42 may be arbitrary. However, in the rotating body 4 constituted by a plurality of disks, it is preferable that 2 to 4 protrusions 42 be provided on each disk. As a result, the portable device α can be sufficiently blown to the collision section 6, and the breakage of LIB can also be suppressed.

  Alternatively, the rotor 41 and the projecting portion 42 may be prepared as separate members, and they may be assembled to form the rotating body 4, or the rotor 41 and the projecting portion 42 integrally formed may be used as the rotating body 4. .

  Further, in the present embodiment, a gap of such a size that the LIB, which is made to collide with the collision part 6 and is separated from the portable device α, can fall without being caught between the rotating body 4 and the inner wall of the processing chamber 2 Is provided. This gap is at least a part (LIB and a substrate) separated from the portable device α (in addition to the portable device α after the collision with the collision portion 6), without causing the rotating body 4 to collide again with the collision portion 6 It can be appropriately adjusted according to the size and input amount of the portable device so that it can be collected.

The above clearance can be adjusted as the distance between the end point side (downstream side) of the rotation direction of the rotary body 4 shown in FIG. 1, that is, the part on the right side and the inner wall of the processing chamber 2 and the collision part 6. By doing this, when a plurality of collision parts 6 (collision members 62) to be described later are provided, it slips between the collision member 62 positioned closest to the end side (downstream side) in the rotational direction and the rotating body 4 The LIB can be dropped below the rotating body 4 without being caught between the rotating body 4 and the inner wall of the processing chamber 2. That is, it is possible to recover LIB with little disruption of LIB.
In addition, the place of the gap may be provided other than the above place, for example, by providing a gap between the rotating body 4 and the inner wall of the processing chamber 2 when viewed in the central axis direction of the rotating body 4 I don't care. Therefore, the “gap” described in the present embodiment includes other than the gap shown in FIG. However, for convenience of explanation, a gap may be mentioned as a representative example of the gap.

1-D) Scattering part 5
The scattering unit 5 in the present embodiment scatters positions where the portable device α collides with the rotating body 4 when the plurality of portable devices α are introduced into the processing chamber 2 from the input unit 3 It is a part that As described above, in the present embodiment, it aims to “apply an appropriate shock at one time” in order to separate LIB from the portable device α. On the other hand, when the portable device α is inserted into the idle unit from the input unit 3, it is also expected that the portable device may be inserted into a predetermined portion of the rotating body 4. In such a case, if it should be made to collide with the collision part 6 without being brought into contact with another portable device α after being blown by the projection part 42, the portable equipment α collide with each other before the collision with the collision part 6 There is also the possibility of taking the opportunity of giving a moderate impact at one time. Therefore, in the present embodiment, the provision of the scattering portion 5 makes it possible to suppress the above-mentioned fear.

  The configuration of the scattering unit 5 may be arbitrary as long as the position at which the portable device α collides with the rotating body 4 can be scattered. To cite a specific configuration example, for example, an opening having a width which can sufficiently pass between the input port of the input unit 3 and the front of the processing chamber 2 to secure the interval between the portable devices α. You may provide the grid | lattice which equipped with two or more. In addition, between the input port of the input unit 3 and the front of the processing chamber 2, the flow of the portable device α in the inside of the input unit 3 is intended to be a watershed when moving the plurality of portable devices α. In order to divide it into a plurality of parts, a protruding part may be provided which is perpendicular to the moving direction of the portable device α and perpendicular to the paper surface of FIG. Of course, the configuration as described above may be provided in front of the input unit 3, and in some cases, may be provided in the processing chamber 2.

1-E) collision part 6
The collision unit 6 in the present embodiment is a portion to be a collision destination of the portable device α blown away by the rotating body 4 and has a configuration capable of separating LIB from the portable device α by an impact at the time of a collision. Point to something.

The collision part 6 has a collision surface capable of realizing the above contents, and has a hardness and a shape capable of releasing the fixed state of LIB contained in the portable device α and separating the LIB from the portable device α. There is no particular limitation as long as the collision surface has. If the specific example of the collision part 6 is mentioned, the member 62 for collisions attached to the connection member 61 provided with respect to the inner wall of the processing chamber 2 or the inner wall of the processing chamber 2 is mentioned. In the present embodiment, an example using the collision member 62 will be described.
Less than,
.Connection member 61 provided on the inner wall of the processing chamber 2
· A collision member 62 attached to the connection member 61
Will be explained.

1-E-a) connecting member 61
The connection member 61 in the present embodiment has a function of connecting the processing chamber 2 and the collision member 62. Well-known members may be used as long as they have this function.

The collision member 62 is provided at an arbitrary position away from the inner wall of the processing chamber 2 by using the connecting member 61. By doing this, first, it becomes possible to reduce damage and wear of the inner wall of the processing chamber 2.
Further, it is possible to adopt a configuration in which the collision member 62 can be attached to and detached from the processing chamber 2. That is, even if the processing apparatus 1 of the present embodiment is used for a long time, if only the collision member 62 is replaced, it is possible to maintain a state of less damage and wear.

  Of course, although a combination of the connecting member 61 and the collision member 62 may be used as the collision portion 6, the separate member can cope with the situation where only the collision member 62 can be replaced, which is preferable.

  Furthermore, if it is a separate body, the structure which can adjust the angle with respect to the rotary body 4 of the member 62 for collisions is employable. By adopting this configuration, it is possible to adjust the angle of the collision surface of the collision member 62 with respect to the rotating body 4 in accordance with the portable device α to be processed and the LIB to be collected.

  By adjusting the angle, it is possible to adjust the degree of impact given to the portable device α. For example, when the trajectory along which the portable device α is blown is a tangential direction of the circumference of the rotating body 4, if it is desired to increase the degree of impact, the collision surface may be provided to face the tangential direction of the circumference. . On the other hand, if the portable device α has only a relatively low strength, there is a possibility that the impact of the collision may cause the portable device α and hence LIB to be broken. In that case, the angle of the collision member 62 may be changed so that the collision surface does not face the tangent direction of the circumference.

  Further, by changing the direction of the collision surface, it becomes possible to drop the portable device α after the collision from the gap or the like immediately after the collision with the collision surface. In other words, it is also possible to change the direction of the collision surface so that the number of collisions of the portable device α tends to be one.

1-E-b) collision member 62
The collision member 62 in the present embodiment is a portion having a collision surface which is a collision destination of the portable device α blown away by the rotating body 4. Then, the collision member 62 has a function of separating LIB from the portable device α by the impact at the time of the collision. Well-known members may be used as long as they have this function.

  As a preferred embodiment of the collision member 62, the 1-E-a) connection member 61 was mentioned earlier, but by providing the collision surface separately from the inner wall of the processing chamber 2, the inner wall of the processing chamber 2 is provided. It has the effect of being able to control the damage and wear of the

  Further, as another preferable embodiment of the collision member 62, as shown in FIG. 1, the collision surface has a curved shape indented toward the rotating body 4, and the rotating body 4 is formed on the extension of the curved shape. There is a configuration in which

  First, since the collision surface has the curved shape as described above, the portable device α blown away by the rotating body 4 collides with the collision surface, and then smoothly travels along the curved shape and falls. In the shape other than the curve, while the portable device α is blown from one to the next, there are cases where a plurality of portable devices α stay on the collision surface.

  As the shape of the collision surface, a plurality of protrusions may be provided on the surface of the curved shape in order to increase the degree of impact to be applied. The shape and the material of the collision surface may be appropriately set according to the type of the mobile device α and the degree of the shock to be given.

  Moreover, as another preferable form of the collision part 6, as shown in FIG. 1, the structure which provides multiple collision parts 6 (namely, member 62 for collisions) along with the rotation direction of the rotary body 4 is mentioned. Of course, the number of collision members 62 is not limited to two, and may be three or more.

  By providing a plurality of collision members 62 side by side in the rotational direction, the following effects can be obtained. Even if the portable device α does not collide with the first collision member 62 (upstream side), and the clearance between the first collision member 62 (upstream side) and the rotating body 4 is lost, the second It is possible to cause a collision with the collision member 62 (downstream side).

  Further, in that case, it is preferable that the collision member 62 be disposed such that the end portions of the plurality of collision portions 6 of the plurality of collision portions 6 overlap with each other as viewed from the rotation center of the rotating body 4. This makes it possible to cause the portable device α to collide once.

  Moreover, it is preferable that the collision part 6 is arrange | positioned in the position where the clearance gap between each collision part 6 and the rotary body 4 becomes narrow as it goes to a rotation direction among the collision parts 6 provided with two or more. In FIG. 1, the gap between the second collision member 62 (downstream side) and the rotating body 4 is smaller than the gap between the first collision member 62 (upstream side) and the rotating body 4. It is set narrowly. By doing this, it is possible to suppress the possibility that the portable device α after being skipped may slip through all the collision parts 6.

  In the above case, the collision part 6 is formed of the connecting member 61 and the collision member 62, but other members may of course be provided as the collision part 6. In addition, the collision part 6 may be used as the inner wall of the processing chamber 2 in the first place. In that case, by changing the shape of the inner wall of the processing chamber 2 to a shape preferable for the collision member 62 described above, the examples listed above are applicable even when the collision portion 6 is the inner wall of the processing chamber 2 It is. However, as described above, it is more advantageous to provide the collision member 62 separately from the inner wall of the processing chamber 2.

1-F) Reservoir or Ejection Unit It is preferable that a storage unit for recovering the processed portable device α and the separated LIB is provided below the rotating body 4 (not shown). By doing this, it is possible to suppress the portable device α from being caught between the rotating body 4 and the inner wall of the processing chamber 2. In addition, as the storage unit, for example, the portable device α is guided so that the portable device α after colliding with the collision portion 6 does not return on the rotating body 4 (in other words, away from the rotating body 4) A guide portion may be formed, and the arrangement and shape of the connection member 61 of the collision portion 6 and the collision member 62 may be appropriately adjusted.

  In addition to the above configuration, a configuration that is appropriately required for an apparatus for processing used portable device α may be adopted.

<2. Processing method of portable device α>
Next, a method of processing the portable device α in the present embodiment will be described. In addition, the contents of the following steps are <1. There is also a portion that overlaps the content described in the section of the processing device 1> of the portable device α. Therefore, for the contents not described below, <1. This is as described in the section of the processing device 1> of the portable device α.

2-A) Loading Step In the loading step, the portable device α is loaded into the processing chamber 2. The processing method of the portable device α in this embodiment can be performed continuously, unlike the batch method. Therefore, the portable device α may be inserted continuously. Further, when the scattering unit 5 described above is installed inside the input unit 3 and the plurality of portable devices α are inserted into the processing chamber 2 from the input unit 3, the portable device α collides with the rotating body 4 You may perform the scattering process which disperses the position which However, even in the case where the scatterer 5 is not provided, it is possible to separate the LIBs by performing the following steps to achieve the effects of the present invention.

  Incidentally, although it will be described in the item of the embodiment described later, there is also a case where it is not always possible to separate LIB from all the mobile devices α when the plurality of mobile devices α are continuously inserted. However, when recovering LIB from a used portable device, there is no change in being able to efficiently recover LIB without relying only on manual operations and suppressing LIB breakage. As a result, as a matter of course, when the portable device α is inserted alone, the present embodiment is sufficiently adaptable even when the plurality of portable devices α are continuously inserted.

2-B) Battery separation step In the battery separation step, the portable device α is blown off by the rotation of the rotating body 4 disposed in the processing chamber 2 and collides with the collision part 6 to cause the portable device α to collide. Separate LIB from

  Then, in the loading step, the portable device α is loaded toward the portion on the starting point side (that is, the upstream side) of the rotational direction of the rotating body 4 among the upper half portion of the rotating body 4. By doing this, it is possible to vigorously jump the portable device α to the collision part 6, and an appropriate impact can be given at one time.

  Further, a gap of a sufficient size is provided between the rotating body 4 and the processing chamber 2. Therefore, LIB, which is caused to collide with the collision part 6 and is separated from the portable device α, can be dropped without being caught between the rotating body 4 and the processing chamber 2.

  When recovering LIB from the portable device α, the rotational speed of the circumferential surface of the rotating body 4 (specifically, the protrusion 42, more specifically, the central portion of the protrusion 42) is 7.5 m / s or more (number of rotations) The frequency is preferably 15 Hz (1 / s) or more, and 10 m / s or more (rotational speed 20 Hz (1 / s) or more). This makes it possible to apply an appropriate impact to the portable device α at one time. Specifically, if it is 7.5 m / s or more, LIB can be reliably separated in the case of a portable device α having a battery-replaceable lid. And, if it is 10 m / s or more, LIB can be separated reliably and efficiently even in the case of a LIB integrated portable device α that has a structure in which battery exchange by the end user of the portable device α is impossible, and as much as possible It becomes possible to reliably separate LIB for various types of portable devices α.

  In order to prevent damage to LIB, it is preferable to set the rotational speed of the circumferential surface of the rotor 4 to 25 m / s or less (50 Hz or less). Furthermore, it is very preferable to set the rotational speed of the circumferential surface of the rotating body 4 to 15 m / s or less (30 Hz or less). As shown in the below-mentioned Example which collect | recovered LIB from the used smart phone, under this condition, it becomes possible to collect | recover LIB by a storage part, after crushing reduces possibility of breakage naturally.

  In the present embodiment, the portable device α is processed by performing the above steps. However, in addition to the above steps, the following steps are preferably performed additionally.

2-C) Re-Injection Step In this step, the portable device α itself after the battery separation step or its parts are collected by the storage section, and then those that need to be re-introduced are introduced into the processing chamber 2.

There are two main reasons for performing this process.
One of the problems is, as described above, that the LIB is not separated in one collision against the portable device α, and then introduced into the processing chamber 2 again (first re-input) Process). In this case, after this step, the same operation as the above-described battery separation step may be performed.

  Another reason other than the LIB separation re-challenge is separation of parts other than LIB (eg, substrate) from the portable device α (second re-loading step). There are members formed of various valuable metals also on the substrate mounted on the portable device α. In addition, the gold grade of the portable device α after separation of LIB is often improved. Even if this is not the case, the substrate is often useful as a smelting material. Therefore, collecting the substrate often contributes to the improvement of the economic efficiency. When this process is performed for this reason, the following processes are performed.

2-D) Substrate separation step In this step, the substrate is separated from the portable device α by an impact when the re-inserted portable device α is blown off by the rotation of the rotating body 4 and collides with the collision part 6. The first and second re-introduction steps may be performed together. However, it is preferable to perform both steps separately. Specifically, in the second re-introduction step, it is preferable to increase the rotational speed of the circumferential surface of the rotating body 4 more than the 2-B) battery separation step mentioned above. The reason is as follows.

  As described above, LIB is not firmly fixed to the portable device α, but in some cases, fixed to the inside of the portable device α by an adhesive. However, unlike the LIB, the substrate is often fixed to the portable device α by a locking member such as a screw. Therefore, the rotational speed of the circumferential surface of the rotating body 4 is made larger than in the battery separation step, the impact at the time of collision with the portable device α is increased, and the substrate is easily separated from the portable device α.

  After the substrate is separated from the portable device α by the above-described method and the substrate is recovered through the storage unit or the discharge unit, sieving, magnetic separation and the like are appropriately performed. Note that after collecting a predetermined component from the substrate, the substrate may be crushed, and the material may be collected for every material (for example, every iron or copper) that made up the substrate. Thereafter, the elements may be recovered for each element by magnetic separation processing or an XRF sorter.

<3. Effects of the embodiment>
According to the present embodiment, the following effects can be obtained.

  In the present embodiment, separation of LIB can be made reliable by adopting a configuration aiming at “providing a suitable impact at one time”. As a result, when recovering LIB from the used portable device α, it is possible to provide a technique for recovering LIB without relying only on manual work and suppressing the breakage of LIB.

  The LIB to be collected in the present embodiment (including the second embodiment described below; the same applies in the following) is not particularly limited as long as it is built in the portable device α provided with the touch panel display. As mentioned above, various cases are required, such as when attaching a rectangular LIB, and in some cases, a laminate LIB (battery pack) formed by inserting an electrolytic solution and an electrode into a resin film, to the thin portable device α, etc. This embodiment is also applicable to the case of.

  On the other hand, this embodiment has a remarkable effect when the lid for attaching / removing the LIB is not separately provided on the exterior of the portable device α. The reason is as follows.

  First, the necessity of recovering LIB built in the portable device α is as described above. At the time of recovery of LIB, depending on the portable device α, there may be a case where a lid for attaching and detaching LIB is provided on the exterior. Even in this case, the present embodiment is applicable, but the ease of operation is improved as long as the lid is attached. In such a case, it is often the case that the skill level is not necessary for work, and the advantage of automation over manual separation of LIB is diminished.

  On the other hand, with the thinning of the portable device α, the miniaturization and thinning of LIB are also in progress. In that case, the durability of LIB can not be as fragile as before. In some cases, when the end user of the portable device α tries to exchange LIB, the possibility of damaging LIB can not be denied. As a countermeasure, there are many cases where a lid for attaching / removing the LIB is not separately provided on the exterior of the portable device α.

  If this measure is adopted, the end user of the portable device α can not replace the LIB, but it takes a lot of time to separate the LIB from the used portable device α as in this case.

  Note that, depending on the portable device α, the lid for attaching / removing the LIB may not be separately provided on the exterior of the portable device α, and the entire exterior may be a lid for attaching / removing the LIB. In this case, although separation of the LIB is easier than when the lid itself for attaching and detaching the LIB is not provided on the exterior of the portable device α, when only the LIB can be visually recognized and grasped when the lid is opened. In comparison, work efficiency falls clearly.

  However, by applying the present embodiment, even if the lid for attaching / removing the LIB is not separately provided on the exterior of the portable device α, the shredding of the LIB is suppressed without relying only on the manual operation. At the same time, it is possible to recover LIB. As a result, in order to increase the effect of the present embodiment, it is preferable that a lid for attaching / removing the LIB is not separately provided on the exterior of the portable device α.

  As described above, in the present embodiment, an example of LIB is given as the secondary battery. Of course, the present invention is applicable to any other known secondary battery.

Second Embodiment
The second embodiment will describe a method of separating LIB by dropping a portable device α (for example, a smartphone) from a high place. As an object to be processed, a case will be described in which a portable device α is used in which a LIB is built in and a lid for attaching and detaching the LIB is not separately provided on the exterior. Note that the items not described below are the same as the contents described in the first embodiment.

  In the battery separation step of the present embodiment, LIB is separated from the portable device α by causing the portable device α to collide with the collision part after the predetermined acceleration is given and the predetermined speed is achieved.

  The “predetermined acceleration” referred to here may be an acceleration (ie, a gravitational acceleration g) applied by dropping the portable device α by its own weight as illustrated in the present embodiment. Also, of course, the acceleration may be given by being blown off by the projecting portion 42 in the processing apparatus described in the first embodiment.

  In addition, the “predetermined speed” before causing the portable device α to collide with the collision part may be a speed corresponding to the rotation speed described in the first embodiment.

  Incidentally, in the first embodiment, an example of processing the portable device α which is a tablet terminal (for example, one having a touch panel display) incorporating a secondary battery (for example, LIB) has been described. It may be an example not limited to the terminal. However, in order to increase the effect of the present invention, it is preferable to treat a portable device α that is not separately provided with a lid for attaching and detaching the LIB.

  Next, the present invention will be specifically described by way of examples. Of course, the present invention is not limited to the following examples.

  In the present embodiment, a used smartphone (hereinafter simply referred to as “smart phone”) is selected as a test target among mobile devices. Among them, the iPhone (registered trademark) terminal (hereinafter referred to as terminal X) and the Android (registered trademark) terminal (hereinafter referred to as terminal Y) are selected.

(Reference Example 1)
As a test, first, as a reference example 1, the terminal X was manually disassembled.
The cover of the terminal X is not separately provided with a lid for attaching / removing the LIB. Therefore, it took about 15 seconds to remove the exterior (rear surface) of the terminal X. In addition, LIB of terminal X is a laminate type battery pack, which is fixed by adhering to the main body, and it took about 15 seconds to separate LIB.
As a result, the total time for recovering LIB from terminal X was about 30 seconds.
In addition to the recovery of LIB, the time taken to further recover the substrate from terminal X was 100 seconds, and the time taken to completely disassemble terminal X was 200 seconds.

(Reference Example 2)
Similarly to the above test, as a reference example 2, the terminal Y was also manually disassembled. In addition, as the terminal Y, the test was carried out on a terminal to which a square LIB was attached and a terminal to which a laminate type battery pack was attached as in the terminal X. Further, as in the case of the terminal X, a lid for attaching and detaching the LIB is not separately provided on the exterior of the terminal X.
As a result, the total time to recover LIB from terminal Y was about 10 seconds in the case of LIB being a square, and about 60 seconds in the case of LIB being a battery pack.

Example 1
In the present example, the test was performed using the processing apparatus of the portable device described in the first embodiment. The distance (W1) between the rotor 4 and the collision part 6 in the processing apparatus was fixed at 100 mm. And the rotational speed of the circumferential surface of the rotating body 4 is 5 m / s (10 Hz), 7.5 m / s (15 Hz), 10 m / s (20 Hz), 15 m / s (30 Hz), 20 m / s (40 Hz), 25 m The tests were carried out in each case as / s (50 Hz), 30 m / s (60 Hz). In addition, it is assumed that one terminal X is loaded into the processing apparatus.

  FIGS. 2A and 2B show photographs of the terminal X and the parts (including LIB) present therein after the processing. 2A (a) to (d) and FIG. 2B (e) to (g) show rotational speeds of 5 m / s, 7.5 m / s, 10 m / s, 15 m / s, 20 m / s, 25 m / s, respectively. , Corresponding to 30 m / s. 2A and 2B, in the case of terminal X, LIB (part surrounded by a dotted line in the figure) is separated from terminal X when the rotational speed is 10 m / s or more after the stage of FIG. 2A (c) did it. In addition, prior to the stage of FIG. 2B (f), that is, at a rotational speed of 25 m / s or less, excessive fracture where the end of LIB is missing did not occur. Even better, before the stage of FIG. 2A (d), ie, at a rotational speed of 15 m / s or less, there was almost no damage to LIB despite being a battery pack.

(Example 2)
Using the same method as in Example 1, a test was also performed on one terminal Y incorporating a square LIB. As a result, it was possible to separate LIB from terminal Y when the rotational speed was 7.5 m / s or more.

(Example 3)
In the present example, as in Example 1, a test was performed using the processing apparatus of the portable device described in the first embodiment. In addition, the rotational speed of the surrounding surface of the rotary body 4 was 10 m / s (20 Hz). After that, three terminals X were continuously fed into the processing apparatus.

FIG. 3 shows a photograph of the terminal X and the LIB existing therein after the processing. Referring to FIG. 3, LIB can be separated from terminal X. Moreover, although the LIB was a battery pack, almost no damage occurred.
In addition, it took only 3 seconds for working time. Therefore, the cost required for the operation could be reduced to about 1/6 of that of Reference Example 1 using the terminal X, even if the cost required for the controller of the apparatus and the introduction / transportation of the terminal X was taken into consideration.

(Example 4)
The test was performed using the processing device of the portable device described in the first embodiment, using the same method as that of the third embodiment. In addition, 20 terminals X were continuously introduced into the processing apparatus.

FIG. 4 shows a photograph of the terminal X and the LIB existing therein after the processing. Note that due to space, only a few of the terminals X except LIB are shown in FIG. Referring to FIG. 4, LIB could be separated from 15 terminals X out of 20. In other words, LIB could be efficiently recovered even with the continuous input of a large number of 20 terminals X. Moreover, although LIB was a battery pack, almost no damage occurred to any LIB.
In addition, it took only 3 seconds for working time. Therefore, the cost required for the operation could be reduced to about 1/6 of that of Reference Example 1 using the terminal X, even if the cost required for the controller of the apparatus and the introduction / transportation of the terminal X was taken into consideration.

(Example 5)
The test was performed using the processing device of the portable device described in the first embodiment, using the same method as that of the third embodiment. In addition, 16 terminals Y were continuously introduced into the processing apparatus.

FIG. 5 (a) shows a photograph of the terminal Y after the processing, and FIG. 5 (b) shows a photograph of the LIB existing inside. As can be seen from FIGS. 5A and 5B, LIB could be separated from 14 out of 16 terminals Y. In other words, LIB could be efficiently recovered even in the continuous feeding of a large number of 16 terminals Y. Moreover, almost no damage occurred to any LIB.
In addition, it took only 3 seconds for working time. Therefore, the cost required for the operation could be reduced to about 1/6 of that of Reference Example 2 using the terminal Y, even if the cost required for the controller of the apparatus and the introduction / transportation of the terminal Y was taken into consideration.

  As a result of the above, according to this embodiment, when recovering LIB from a used portable device, it is possible to efficiently carry out LIB without relying only on manual work, and suppressing the breakage of LIB constituting the portable device. It turned out that it is recoverable.

When the contents described above are summarized and the present invention is applied to as many portable devices as possible, the following configuration is obtained.
