Description

The present invention relates to a parts packing device in which small parts such as electronic parts are housed in a carrier tape accommodating portion and packed by taping.

In the electronic component manufacturing line, the manufactured electronic components are aligned using a parts feeder, undergo a predetermined inspection, and then packaged and shipped. Carrier tape may be used for packaging the parts.

The carrier tape is a long and thin strip-shaped member, and a plurality of recesses (accommodating portions) for accommodating electronic components are arranged at equal intervals in the longitudinal direction thereof. In the carrier tape, after electronic components are sequentially loaded into each accommodating portion, a cover tape also made of a long and thin strip-shaped member is superposed on the opening side surface of the recess, and these are sandwiched. It is heat-bonded and packed.

Before the cover tape is heat-bonded to the carrier tape, the electronic parts housed in the housing are inspected, defective electronic parts are removed, replaced with new electronic parts, and then heat-bonded with the cover tape. Have been proposed (Patent Document 1 and Patent Document 2 below).

However, in Patent Document 1 below, the inspection position for inspecting the accommodating portion of the carrier tape, the removal position for removing the defective electronic component from the accommodating portion, and the accommodating portion from which the electronic component has been removed are replenished with new electronic components. The replenishment position and the replenishment position are all performed at the same position. Therefore, in the technique shown in Patent Document 1, it is necessary to arrange and operate the mechanisms for performing each operation at the same position so as not to collide, which complicates the apparatus and takes a long time to stop the carrier tape. Therefore, there is a problem that work efficiency is poor.

Further, in Patent Document 2 below, the inspection position for inspecting the accommodating portion of the carrier tape and the removal position for removing defective electronic components from the accommodating portion are the same positions, and the operation of retreating the inspection mechanism after the inspection is performed. In addition to being necessary, it is necessary to move the removal mechanism closer after the inspection mechanism has been evacuated. This point is the same as in Patent Document 1, and the time for stopping the transfer operation of the carrier tape becomes long, which deteriorates the work efficiency.

Further, in Patent Document 2, the storage position of the electronic component in the carrier tape and the replenishment position for replenishing the storage portion from which the electronic component has been removed are at the same position. Therefore, in the technique shown in Patent Document 2, after removing the defective electronic component, it is necessary to move the carrier tape in the direction opposite to the normal traveling direction to replenish the new electronic component.

If the carrier tape is once returned and then moved in the traveling direction, the work efficiency is further deteriorated, and the work process of attaching the cover tape in the subsequent process is adversely affected. When the cover tape is attached in the subsequent process, the cover tape sent out from the roll is continuously attached to the surface of the carrier tape, but when the carrier tape moves in the opposite direction to the progress, the cover tape becomes loose. May occur. If the cover tape is loosened, the cover tape may not adhere well to the surface of the carrier tape.

Japanese Patent No. 5219056 Japanese Patent No. 5633950

The present invention has been made in view of such an actual situation, and an object of the present invention is that it is easy to efficiently eliminate defective parts housed in a carrier tape accommodating portion in a short time and replace them with replacement parts. The mechanism is to provide a simple parts packing device while being excellent in work efficiency.

In order to achieve the above object, the parts packing device according to the present invention is
A parts packing device for accommodating parts in a plurality of accommodating portions arranged in the longitudinal direction of the carrier tape.
A transfer unit that transfers the carrier tape along the transfer direction, and a transfer unit.
A component loading section that is arranged at a loading position in the middle of the transfer section and loads the component in the accommodating section.
An visual inspection unit that is arranged at an inspection position on the downstream side in the transfer direction from the component loading unit and inspects the parts transferred to the inspection position by the transfer unit.
It is arranged at the removal and replenishment position on the downstream side in the transfer direction from the inspection position, the part is taken out from the housing part according to the inspection result of the visual inspection part, and is replaced with the housing part from which the part is taken out. It is characterized by having a removal and replenishment unit for replenishing the replenishment parts.

In the parts packing device according to the present invention, the loading position, the inspection position, and the removal / replenishment position are arranged so as to be displaced in this order along the transfer direction. Therefore, after the inspection is performed at the inspection position, it is not necessary to stop the carrier tape in order to evacuate the inspection mechanism and bring the discharge mechanism closer, and the carrier tape can be immediately moved to the removal / replenishment position. ..

At the removal / replenishment position, the removal / replenishment unit takes out the parts determined to be defective from the accommodating unit according to the inspection result of the visual inspection unit, and replenishes the accommodating unit from which the parts have been taken out with a substitute replenishment part. That is, in the apparatus of the present invention, it is easy to efficiently eliminate defective parts housed in the carrier tape accommodating portion in a short time and replace them with replacement parts, which is excellent in work efficiency and has a mechanism. It has the advantage of being simple.

Further, since the loading position, the inspection position, and the removal / replenishment position are arranged so as to be displaced in this order along the transfer direction, it is not necessary to move the carrier tape in the direction opposite to the traveling direction. .. Therefore, there is no possibility of adversely affecting the cover tape affixing work process in the subsequent process. When attaching the cover tape in the subsequent process, the cover tape sent out from the roll is continuously attached to the surface of the carrier tape, but since the carrier tape does not move in the opposite direction to the progress, the cover tape is attached. It is easy to keep the tension constant, and the cover tape can be well adhered to and fused to the surface of the carrier tape. Therefore, the sealing and sealing of the parts to the accommodating portion of the carrier tape is improved.

The imaging means for imaging the accommodating portion at the inspection position by the visual inspection unit may be movable to the removal replenishment unit. In the removal replenishment unit, the imaging means can image the replenishment component replenished in the accommodation unit and perform a re-inspection. If the replacement parts in the accommodating portion are not defective by the re-inspection, the carrier tape is sent in the transfer direction, and the imaging means returns to the inspection position in order to inspect the next accommodating portion at the inspection position.

By moving the imaging means at the same time as sending the carrier tape in the transfer direction in this way, it is possible to eliminate wasted time and improve work efficiency, and it is possible to reduce the number of imaging means. Moreover, since the inspection and the re-inspection are performed using the same imaging means, the quality of the inspection is stable. It should be noted that separate imaging means may be arranged at both the inspection position and the removal / replenishment position.

Preferably, the removal and replenishment unit has a discharge unit that discharges the component taken out from the storage unit at a discharge position located outside the transfer unit of the carrier tape. By arranging the discharge unit outside the transfer unit instead of inside the transfer unit, the device configuration is simplified.

Preferably, the removal and replenishment section has a replacement component capture section that captures the replacement component at a replacement component capture position located outside the carrier tape transfer section. By arranging the alternative parts intake unit outside the transfer unit instead of inside the transfer unit, the device configuration is simplified.

Preferably, the removal and replenishment section has a pickup nozzle and
The pickup nozzle is movable between the removal replenishment position, the discharge position, and the replenishment component intake position. By moving the pickup nozzle between the removal and replenishment position, the discharge position, and the replenishment component intake position, the work efficiency of component removal and replenishment is improved.

Preferably, the pickup nozzle is held by a rotating mechanism and
It can be rotationally moved between the removal and replenishment position, the discharge position, and the replenishment component intake position. By moving the pickup nozzle with a rotating mechanism, the work efficiency of removing and replenishing parts is improved.

The pickup nozzle is held by the straight-ahead mechanism.
It may be possible to move straight back and forth between the removal and replenishment position, the discharge position, and the replenishment component intake position. Even in this case, by moving the pickup nozzle with a straight-ahead mechanism, the work efficiency of removing and replenishing parts is improved.

A protective cover may be arranged on the surface of the carrier tape located on the downstream side in the transfer direction from the component loading portion. By providing the protective cover, it is possible to effectively prevent foreign matter such as dust from being mixed into the accommodating portion before the accommodating portion containing the parts is sealed with the cover tape. ..

Preferably, at least a portion of the protective cover corresponding to the inspection position is transparent. With this configuration, at the inspection position, the parts housed in the housing can be inspected through the transparent protective cover.

Further, preferably, at least a part of the protective cover corresponding to the removal / replenishment position is composed of a transparent member capable of exposing the housing portion and moving with respect to the cover main body. The transparent member is removed by moving the transparent member, for example, in a direction intersecting the transfer direction. Parts housed in the housing corresponding to that position can be removed from the housing and replaced with alternative replacement parts. After that, the transparent member closes the accommodating portion, and the replenishing parts accommodated in the accommodating portion are re-inspected for defects through the transparent member. If defects are observed by re-inspection, parts removal and replacement of replacement parts are repeated.

In the transfer unit, the transfer roller 4 that unwinds the carrier tape 3 from the carrier tape supply roll 31 and feeds it in the transfer direction X1 and the carrier tape 3 directed from the transfer roller 4 in the transfer direction X1 are intermittently transferred in the transfer direction X1. It has a feeding mechanism (not shown). The feeding mechanism engages with, for example, the feeding hole 32 of the carrier tape 3 and applies a force for moving the carrier tape 3 in the transfer direction X1. The feed mechanism is controlled by the control unit (control means) 10 shown in FIG. 1B.

As shown in FIGS. 2 and 3A, the carrier tape 3 is formed with concave accommodating portions 32 at substantially equal intervals along the X axis in the longitudinal direction thereof. The electronic component 1 can be accommodated in the accommodating portion 32 from the upper part in the Z-axis direction. Further, as shown in FIG. 3A, feed holes 33 are formed at substantially equal intervals along the X-axis direction at the ends of the carrier tape 3 in the Y-axis direction. In the example shown in FIG. 3A, feed holes 33 are formed at substantially equal intervals along the X-axis direction only at one end of the carrier tape 3 in the Y-axis direction, but feed holes are formed at both ends in the Y-axis direction. 33 may be formed at substantially equal intervals along the X-axis direction.

In the drawings, the X-axis, the Y-axis, and the Z-axis are substantially perpendicular to each other, and in the present embodiment, the X-axis is parallel to the transfer direction X1 of the carrier tape 3. Further, the recessed direction of the accommodating portion 32 is substantially parallel to the Z axis.

It has a portion 7 and a seal portion 8. The component loading unit (component loading means) 5 has a member for loading the electronic component 1 into the empty accommodating portion 32 of the carrier tape 3 located at the loading position 51.

As a member for loading the electronic component 1 into the empty accommodating portion 32, for example, a pickup nozzle is exemplified. The component loading unit 5 is controlled by the control unit 10 shown in FIG. 1B.

The electronic component 1 loaded in the accommodating portion 32 is not particularly limited, and examples thereof include a multilayer ceramic capacitor, an inductor element, chip beads, and a piezoelectric element. The size of the accommodating portion 32 is determined according to the size of the electronic component 1. The material of the carrier tape 3 is not particularly limited, and examples thereof include polystyrene, polyethylene terephthalate, and polypropylene.

At the inspection position 61 on the downstream side of the transfer direction X1 from the component loading position 51, an appearance inspection unit (appearance inspection means) 6 for inspecting the electronic component 1 transferred to the inspection position 61 is arranged. The visual inspection unit 6 includes an imaging device (imaging means) 62 such as a CCD, and, if necessary, a lighting device (not shown).

As shown in FIG. 3A, at the removal / replenishment position 71 on the downstream side of the transfer direction X1 from the inspection position 61, the electronic component 1 is taken out from the accommodating portion 32 according to the inspection result of the visual inspection unit 6, and the electronic component 1 is moved. A removal replenishment unit (removal assisting means) 7 for replenishing an alternative replenishment component 1a is arranged in the removed accommodating unit 32.

The removal and replenishment unit 7 has a rotary arm mechanism 72. The rotary arm mechanism 72 has a pickup nozzle 73 at the tip of the rotary arm. By rotating the rotary arm, the pickup nozzle 73 can rotate and move between the removal / replenishment position 71 on the carrier tape 3, the discharge position 74, and the component take-in position 75.

The discharge position 74 and the component take-in position 75 are located at the same radius of gyration with respect to the center of rotation of the rotation arm, although they are out of the transfer path of the carrier tape 3. The removal / replenishment position 71 on the carrier tape 3 is also located at the same radius of gyration with respect to the discharge position 74 and the component take-in position 75 with respect to the rotation center of the rotation arm. In the present embodiment, these positions 71, 74, and 75 are displaced with respect to the center of rotation at a predetermined angle such as approximately 90 degrees.

At the discharge position, discharge parts such as trays, saucers, and storage containers (not shown) for accommodating the removed parts 1b for disposal or reuse are installed. At the component take-in position 75, a substitute component take-in portion such as a tray, a saucer, or a storage container in which a supplementary component 1a that is a substitute for the electronic component 1 is installed or is installed is installed.

As shown in FIG. 1A, the pickup nozzle 73 of the rotary arm mechanism 72 takes out the removal part 1b from the accommodating portion 32 at the removal replenishment position 71, rotates the arm, and discharges the removal part 1b at the discharge position 74. Further, the arm is rotated to pick up the replenishment part 1a at the part take-in position 75. After that, the rotary arm rotates in the reverse direction or forward rotation to return to the removal replenishment position 71 on the carrier tape 3, and at that position 71, the pickup nozzle 72 replenishes the empty accommodating portion 32 with the replenishment part 1a. do. The movements of the rotary arm mechanism 72 and the pickup nozzle 73 are controlled by the control unit shown in FIG. 1B. The control method will be described later.

As shown in FIGS. 1A and 1B, there is a seal position 81 on the downstream side of the removal / replenishment position 71 along the transfer direction X1 of the carrier tape 3, and a heating / pressurizing device 82 is installed at the seal position 81. There is. A cover tape feed roller 36 is installed on the upstream side of the transfer direction X1 of the heating and pressurizing device 82. The roller 36 is installed between the removal / replenishment position 71 and the seal position 81. The cover tape feed roller 36 presses the cover tape 34 supplied from the cover tape supply roll 35 against the upper surface of the carrier tape 3, and in that state, feeds the cover tape 34 into the heating and pressurizing device 82.

The cover tape 34 is made of a synthetic resin such as polystyrene or polyethylene terephthalate, and is preferably transparent. Further, it is preferable that the cover tape 34 is subjected to antistatic processing in order to prevent adhesion of electronic components. The Y-axis direction width of the cover tape 34 is preferably equal to or less than the Y-axis direction width of the carrier tape 3, and has at least a width larger than the Y-axis direction width of the accommodating portion 32, and the electronic component 1 accommodates the cover tape 34. The upper opening in the Z-axis direction of the accommodating portion 32 is closed.

In the heating and pressurizing device 82, both ends of the cover tape 34 in the Y-axis direction are continuously heat-sealed to the upper surface of the carrier tape 3 along the X-axis direction of the carrier tape 3. As a result, each electronic component 1 accommodated in the accommodating portion 32 is sandwiched between the carrier tape 3 and the cover tape 34 and sealed inside the accommodating portion 32. The carrier tape 3 in which the electronic component 1 is sealed in the accommodating portion 32 by the cover tape 34 is wound around the carrier tape winding roll 37. The sealing operation by the heating and pressurizing device 82, the cover tape supply roll 35, the cover tape feed roller 36, and the carrier tape take-up roll 37 is controlled by the control unit 10.

As shown in FIGS. 1A and 1B, the accommodating portion 32 accommodating the electronic component 1 is opened upward on the Z axis between the loading position 51 and the seal position 81 along the transfer direction X1. Become. A protective cover 9 is arranged above the carrier tape 3 between the loading position 51 and the seal position 81 in order to prevent dust and dirt from being mixed into the accommodating portion 32 accommodating the electronic component 1. It is preferable that this is done.

The protective cover 9 is preferably arranged above the Z-axis of the carrier tape 3 with a slight gap, and is preferably transparent at least at the inspection position 61. The entire protective cover 9 may be transparent. The reason why it is preferable to be transparent at the inspection position 61 is that the image pickup device 62 images the electronic component 1 housed inside the accommodating portion 32 at the inspection position 61 through the protective cover 9.

Further, the protective cover 9 is intermittent at the removal / replenishment position 71 so that the upper side of the carrier tape 3 can be exposed. A transparent member 91 is arranged on the carrier tape 3 located at the removal / replenishment position 71. The transparent member 91 is movable in the Y-axis direction with respect to the cover main body of the protective cover 9, and is configured so that the accommodating portion 32 can be exposed and protected.

The transparency of the transparent member 91 is preferably substantially the same as the transparency of the protective cover 9 at the inspection position 61. At the inspection position 61, the inside of the accommodating portion 32 is imaged by the imaging device 62 through the protective cover 9, and at the removal replenishment position 71, the inside of the accommodating portion 32 is imaged by the imaging device 62 through the transparent member 91. be. In the present embodiment, the imaging device 62 is movable along the X-axis direction between the inspection position 61 and the removal / replenishment position 71 at the upper portion of the carrier tape 3 in the Z-axis direction.

Next, the control method of the control unit 10 shown in FIG. 1B will be described mainly based on FIG. In step S1 shown in FIG. 4, as shown in FIG. 3A, the control unit so as to stop the feeding operation of the carrier tape 3 in the transfer direction X1 at the loading position 51 and load the electronic component 1 into the accommodating unit 32. Reference numeral 10 output a control signal to a pickup nozzle or the like (not shown).

Next, the control unit 10 shown in FIG. 1B sends a control signal to a feed mechanism (not shown) to advance the carrier tape 3 in the transfer direction X1. Step S1 and the carrier tape 3 are repeatedly fed, and the electronic component 1 is sequentially accommodated in the accommodating portion 32 of the carrier tape 3, and from the stage when the first accommodating electronic component 1 reaches the inspection position 61, step S2 shown in FIG. To start. In step S2, the electronic component 1 housed in the accommodating portion 32 of the carrier tape 3 located at the inspection position 61 is imaged by the imaging device 62 to perform an visual inspection.

In the visual inspection, for example, the following inspections are performed. The inspection is preferably performed automatically by image processing. For example, as shown in FIG. 5A, if the electronic component 1 is not accommodated in the accommodating portion 32 that should be accommodating originally, the visual inspection is defective (NG). Further, for example, as shown in FIG. 5B, the visual inspection is defective (NG) even when the electronic component 1 protrudes from the accommodating portion 32 and is accommodated.

Further, for example, as shown in FIG. 5C, the visual inspection is defective (NG) even when the electronic component 1 housed in the housing unit 32 is worn. Further, for example, as shown in FIG. 5D, the visual inspection is defective (NG) even when the terminal electrode 12 of the electronic component 1 housed in the housing unit 32 is not normal.

In the inspection of the accommodating portion 32 at the inspection position 61, for example, when an appearance defect as shown in FIGS. 5A to 5D is detected, the detection result is based on the detection result of the accommodating portion 32 in which the defect is detected. The control unit 10 shown in FIG. 1B stores the number in a storage means such as a memory. If no defect in the visual inspection is detected in the inspection of the housing unit 32 at the inspection position 61, the process proceeds from step S2 shown in FIG. 4 to step S8, and the control unit 10 shown in FIG. 1B controls the feeding mechanism. Then, the carrier tape 3 is fed.

When a defect in the visual inspection is detected in the inspection of the housing unit 32 at the inspection position 61, the process proceeds from step S2 to step S3 shown in FIG. 4, and the control unit 10 shown in FIG. 1B controls the feeding mechanism. The carrier tape 3 is fed. When the control means 10 detects that the accommodating portion 32 in which the appearance defect stored in the memory or the like is detected is located at the removal / replenishment position 71, in step S3 shown in FIG. Stop the feed operation.

At the same time, the control unit 10 shown in FIG. 1B controls the moving mechanism of the transparent member 91, moves the transparent member 91 in the Y-axis direction, protects the accommodating portion 32 of the carrier tape 3 at the removal and replenishment position 71, and protects the protective cover 9. Release from. Then, the control unit 10 controls the operations of the rotary arm mechanism 72 and the pickup nozzle 73 shown in FIG. 1A, and takes out the electronic component 1 from the accommodating unit 32 of the carrier tape 3 at the removal / replenishment position 71. The control unit 10 has the rotary arm mechanism 72 and the pickup nozzle 73 so that the electronic component 1 is ejected as the removal component 1b at the ejection position 74 shown in FIG. 1A in step S4 shown in FIG. Control.

Next, in step S5 shown in FIG. 4, the control unit 10 shown in FIG. 1B controls the rotary arm mechanism 72 and the pickup nozzle 73 shown in FIG. 1A, and picks up the replacement component 1a at the component loading position 75. do. Next, in step S6 shown in FIG. 4, the control unit 10 shown in FIG. 1B controls the rotary arm mechanism 72 and the pickup nozzle 73 shown in FIG. Transport to 71. At that position, the control unit 10 shown in FIG. 1B controls the pickup nozzle 73 so as to install the replenishment component 1a in the empty accommodating unit 32.

The control step described above is a case where the electronic component 1 to be the removal component 1b is accommodated in the accommodating portion 32, for example, as shown in FIGS. 5 (b) to 5 (d). For example, as shown in FIG. 5A, in the case of an appearance defect such that the electronic component 1 is not accommodated in the accommodating portion 32, steps S3 to S4 shown in FIG. 4 are omitted, and steps S2 to S2 are taken. Move to S5.

After step S6 shown in FIG. 4, step S7 is performed, and the control unit 10 shown in FIG. 1B controls the rotary arm mechanism 72 shown in FIG. 1A to retract the pickup nozzle 73 from the upper position of the carrier tape 3. Let me. At the same time or thereafter, the control unit 10 controls the moving mechanism of the transparent member 91, moves the transparent member 91 in the Y-axis direction, and returns the transparent member 91 to the removal / replenishment position 71 on the carrier tape 3.

At the same time or thereafter, the control unit 10 shown in FIG. 1B controls the imaging mechanism 62 to move from the inspection position 61 to the removal replenishment position 71 at the upper position of the carrier tape 3, and at the removal replenishment position 71. The reappearance inspection of the replenishment component 1b is performed by the imaging mechanism 62. The re-appearance inspection is an inspection similar to the visual inspection in step S2 shown in FIG. If the visual inspection of the replacement part 1b is defective (NG) in step S7 shown in FIG. 4, the process returns to step S3 again, and the control unit 10 shown in FIG. 1B repeats the steps after step S3.

If the appearance inspection of the replenishment part 1b is good (OK) in step S7 shown in FIG. 4, the process proceeds to step S8, and the control unit 10 shown in FIG. 1B controls the feeding operation of the carrier tape 3. Next, in step S9 shown in FIG. 4, the control unit 10 shown in FIG. 1B controls the heating and pressurizing device 82, the cover tape supply roll 35, the cover tape feed roller 36, and the carrier tape take-up roll 37, and controls the cover tape 34. Performs the sealing operation by.

In the electronic component packing device 2 according to the present embodiment, the loading position 51, the inspection position 61, and the removal / replenishment position 71 are arranged so as to be displaced in this order along the transfer direction X1. Therefore, after the inspection is performed at the inspection position 61, it is not necessary to stop the feed mechanism of the carrier tape 3 in order to save the inspection mechanism and bring the discharge mechanism closer, and the carrier tape 3 is immediately removed and replenished. It can be moved to 1.

At the removal / replenishment position 71, the rotary arm mechanism 72 of the removal / replenishment unit 7 is controlled by the control unit 10 shown in FIG. 1B, and the electronic component 1 determined to be defective is removed according to the inspection result of the visual inspection unit 6. As 1b, it is taken out from the accommodating portion 32, and the accommodating portion 32 from which the removed component 1b is taken out is replenished with a substitute replacement component 1a.

It has the advantages of high efficiency and simple mechanism.

Further, since the loading position 51, the inspection position 61, and the removal / replenishment position 71 are arranged so as to be displaced in this order along the transfer direction X1, the carrier tape 3 is arranged in the opposite direction to the transfer direction X1. No need to move to. Therefore, there is no possibility of adversely affecting the sticking and sealing work process of the cover tape 34 in the subsequent process. In the sticking and sealing work of the cover tape 34 in the subsequent process, the cover tape 34 sent out from the roll 35 is continuously stuck on the surface of the carrier tape 3, but the carrier tape 3 is contrary to the progress. Since it does not move, it is easy to keep the tension of the cover tape 34 constant, and the cover tape 34 can be satisfactorily adhered to the surface of the carrier tape 3 and fused. Therefore, the sealing and sealing packaging of the electronic component 1 in the accommodating portion 32 of the carrier tape 3 is improved.

Further, in the present embodiment, the imaging device 62 that images the accommodating portion 32 at the inspection position 61 by the visual inspection unit 6 can be moved to the upper part of the carrier tape 3 located at the removal / replenishment position 71 in the Z-axis direction.

If there is no defect in the replenishment part 1a in the accommodating portion 32 by the re-inspection, the imaging device 62 sends the carrier tape 3 in the transfer direction X1 and inspects the next accommodating portion at the inspection position 61. , Return to the inspection position.

By moving the image pickup device 62 at the same time as sending the carrier tape 3 in the transfer direction X1 in this way, it is possible to eliminate wasted time and improve work efficiency, and it is possible to reduce the number of image pickup devices 62. It will be possible. Further, since the inspection and the re-inspection are performed using the same imaging device 62, the quality of the inspection is stable. It should be noted that separate imaging devices may be arranged at both the inspection position 61 and the removal / replenishment position 71.

Further, in the present embodiment, the removal replenishment unit 7 has a discharge unit that discharges the removal component 1b taken out from the accommodating unit 32 at the discharge position 74 located outside the transfer unit of the carrier tape 3. By arranging the discharge unit outside the transfer unit instead of inside the transfer unit, the device configuration is simplified.

Further, the removal and replenishment unit 7 has a replacement component capture unit that captures the replacement component 75 at the replacement component capture position 75 located outside the transfer portion of the carrier tape 3. By arranging the alternative parts intake unit outside the transfer unit instead of inside the transfer unit, the device configuration is simplified.

Furthermore, the removal / replenishment unit 7 has a pickup nozzle 73, and the pickup nozzle 73 can rotate and move between the removal / replenishment position 71, the discharge position 74, and the replenishment component intake position 75. The pickup nozzle 73 rotates and moves between the removal and replenishment position 71, the discharge position 74, and the replenishment component intake position 75, so that the work efficiency of component removal and replenishment is improved. Further, by moving the pickup nozzle 73 by the rotary arm mechanism 72, the work efficiency of removing and replenishing the electronic component 1 is improved.
