The present invention relates to a cutting device and a method for manufacturing cut products.

Patent Document 1 discloses a cutting device that includes a support base that supports a chuck table that holds the workpiece, a cutting feed means that moves the support base back and forth, a cutting means that cuts the workpiece, a water case that catches cutting chips, and a two-fluid jet nozzle that is fixed to the support base and jets fluids. The cutting device described in Patent Document 1 can wash away and remove cutting chips from within the water case using fluid jetted from the two-fluid jet nozzle that moves integrally with the support base.

Japanese Patent Application Laid-Open No. 2006-218551

In a device such as that described in Patent Document 1, it is assumed that the bottom of the water case is sloped to facilitate the discharge of scraps that have fallen into the water case. When the bottom of the water case is sloped in this way, the distance between the two-fluid spray nozzle and the bottom of the water case changes as the support base moves. This means that the fluid cannot be effectively sprayed onto the scraps, and there is a possibility that the scraps will not be washed away.

The present invention was made in light of the above situation, and the problem it aims to solve is to provide a cutting device and a method for manufacturing cut products that can more reliably discharge scrap material.

The problem that the present invention aims to solve is as described above. To solve this problem, the cutting device of the present invention comprises a processing table that is movable along a linear movement direction, a cutting mechanism that cuts an object placed on the processing table, a receiving member that is positioned below the processing table and is capable of receiving scraps generated when the object is cut by the cutting mechanism on an inclined portion that is inclined along the movement direction, a movable nozzle that is movable in the movement direction in conjunction with the movement of the processing table and sprays a fluid onto the inclined portion, and a position adjustment mechanism that is capable of adjusting the vertical position of the movable nozzle in conjunction with movement of the movable nozzle in the movement direction.

The method for manufacturing a cut product according to the present invention is a method for manufacturing a cut product using the cutting device, and includes the steps of placing the object to be cut on the processing table, and cutting the object by moving the cutting mechanism and the processing table relative to each other.

This invention allows scrap materials to be discharged more reliably.

Furthermore, the rotation direction around the vertical rotation axis is defined as the θ direction.

<Configuration of cutting device 100 according to first embodiment>
First, a configuration of the cutting device 100 according to the first embodiment will be described. In this embodiment, the configuration of the cutting device 100 will be described in the case where, for example, a sealed substrate W in which a substrate on which a semiconductor chip is fixed is sealed with resin is used as an object to be cut by the cutting device 100.

Examples of the sealed substrate W include BGA (ball grid array) package substrates, CSP (chip size package) package substrates, and LED (light emitting diode) package substrates. Furthermore, in addition to the sealed substrate W, sealed lead frames, which are resin-sealed lead frames to which semiconductor chips are fixed, may also be used as the cutting target. Furthermore, wiring boards with single or multiple layers of wiring and no electronic elements or components fixed to them may also be used as the cutting target.

The cutting device 100 shown in Figure 1 is a processing device that cuts a sealed substrate W, which is the object to be cut, into multiple cut pieces (products P). The cutting device 100 comprises, as its components, a substrate supply module A, a cutting module B, and a storage module C. Each component is detachable and replaceable with respect to the other components.

<Substrate Supply Module A>
The substrate supply module A is mainly provided with a substrate supply mechanism 1 and a control unit CTL.

The sealed substrate W to be cut is removed from the substrate supply mechanism 1 and transferred to the cutting module B by a transfer mechanism (not shown). The sealed substrate W transferred to the cutting module B is placed on the cutting table 15, which will be described later.

The control unit CTL controls the operation of each part of the cutting device 100. The control unit CTL controls each part of the cutting device 100, allowing for the loading of sealed substrates W, cutting of sealed substrates W, inspection of products P, and unloading of products P. The control unit CTL can also be provided in a module other than the substrate supply module A. The control unit CTL can also be divided into multiple units. For example, a control unit CTL can be provided in each module, and the control units CTL can be linked together to control each part.

<Cutting Module B>
The cutting module B shown in FIG. 1 is mainly provided with a moving mechanism 13, a cutting table 15, a rotating mechanism 17, and a spindle unit 23.

This embodiment illustrates a twin-cut table type cutting device 100 having two cutting tables 15. The cutting tables 15 can be moved in the front-to-rear direction by the movement mechanism 13, and can be rotated in the θ direction by the rotation mechanism 17.

In addition, this embodiment illustrates a cutting device 100 with a twin-spindle configuration having two spindle units 23. The two spindle units 23 can move independently of each other in the left-right and up-down directions.

In the cutting module B, the sealed substrate W is held on the cutting table 15, and the cutting table 15 and two spindle units 23 are moved relative to each other to cut the sealed substrate W into individual pieces. A blade 23a is attached to the spindle units 23. The blade 23a cuts the sealed substrate W held on the cutting table 15 by rotating in a plane that includes the front-to-back and up-to-down directions. At this time, the sealed substrate W can also be cut while cutting water is sprayed toward the blade 23a from a cutting nozzle 23b (see Figure 3), which will be described later.

<Storage module C>
The storage module C is mainly provided with an inspection table 2 and a tray 3 .

An assembly of multiple products P, which have been cut into individual pieces from the sealed substrate W, is placed on the inspection table 2. The multiple products P are inspected by an inspection camera (not shown) and sorted into non-defective and defective products. The selected non-defective products are stored in tray 3. The selected defective products are stored in a separately prepared tray (not shown) and are excluded from the products P. Note that it is not necessarily necessary to inspect the products P in the storage module C.

<Details of Cutting Module B>
Next, the specific configuration of the cutting module B will be described with reference to Figures 2 to 7. Note that Figure 4 illustrates only the lower part of the cutting module B, omitting the illustration of members provided at the upper part of the cutting module B (such as the second receiving member 14, cutting table 15, rear cover member 18, front cover member 19, and upper cover member 20, which will be described later). Furthermore, since the device configurations of the left and right cutting tables 15 are generally the same, the device configuration of the left cutting table 15 will be mainly described in detail below.

The cutting module B mainly comprises a first receiving member 11, a storage section 12, a moving mechanism 13, a second receiving member 14, a cutting table 15, a rotation mechanism 17, a rear cover member 18, a front cover member 19, an upper cover member 20, a cleaning nozzle 22, and a spindle section 23.

The first receiving member 11 shown in Figures 2 to 5 is a member that receives scraps E generated when cutting the sealed substrate W. The first receiving member 11 is one embodiment of the receiving member of the present application. The first receiving member 11 is formed in a box shape that is open upward and backward. The first receiving member 11 can receive scraps E that have fallen from the cutting table 15 (described below), the second receiving member 14, etc. The first receiving member 11 mainly comprises a protrusion 11a, an opening 11b, an inclined groove 11c, and a side portion 11d.

The protrusions 11a shown in Figures 3 to 5 are portions of the bottom surface of the first receiving member 11 that bulge upward. A pair of protrusions 11a are formed on the left and right to correspond to the cutting table 15. The protrusions 11a are formed to extend in the front-to-rear direction.

The opening 11b shown in Figures 4 and 5 is a portion formed to penetrate the bottom surface of the first receiving member 11 from top to bottom. The opening 11b is formed on the upper surface of the protruding portion 11a. The opening 11b is formed to extend in the front-to-rear direction across both the front and rear ends of the protruding portion 11a.

The inclined groove 11c shown in Figures 3 to 5 is a portion of the bottom surface of the first receiving member 11 formed so that it slopes downward toward the rear. Note that the inclined groove 11c is one embodiment of the inclined portion of the present application. The inclined groove 11c is formed on both the left and right sides of the protrusion 11a. Specifically, the inclined groove 11c is formed in a total of three locations: between the left and right protrusions 11a, and between the left and right protrusions 11a and the side portions 11d (described below). The inclined groove 11c is formed to extend along the front-to-rear direction. The upper surface of the inclined groove 11c is formed so that it slopes downward toward the rear.

The side portion 11d forms the side surface of the first receiving member 11. The side portion 11d is formed to surround the protrusion 11a, opening 11b, and inclined groove portion 11c from both the left and right sides and the front. The side portion 11d is formed to have an appropriate width in the vertical direction.

The storage section 12 is a section that collects scrap material E discharged from the first receiving member 11. The storage section 12 is formed in a box shape that is open at the top. The storage section 12 is located at the rear end of the first receiving member 11. For convenience, in this embodiment, Figure 3 and other figures show the storage section 12 and first receiving member 11 as an integrated unit. However, the first receiving member 11 and the storage section 12 can also be formed as separate members, and the storage section 12 can be configured to be detachable from the first receiving member 11.

The movement mechanism 13 shown in Figures 3 to 6 is used to move the cutting table 15 back and forth. The movement mechanism 13 mainly comprises a moving member 13a, a connecting portion 13b, a nut 13c, a screw shaft 13d, and a cover member 13e.

The moving member 13a supports the cutting table 15 and is movable back and forth. The moving member 13a is formed, for example, in a cylindrical shape. The moving member 13a is positioned above the protrusion 11a.

The connecting portion 13b shown in Figures 3 to 5 is the portion that connects the moving member 13a and the nut 13c. The connecting portion 13b is formed in a longitudinal shape (e.g., a cylindrical shape) that extends vertically. The connecting portion 13b is positioned so that it extends from below to above the first receiving member 11 through the opening 11b. The upper end of the connecting portion 13b is fixed to the moving member 13a.

The nut 13c and screw shaft 13d constitute a ball screw mechanism. The screw shaft 13d is positioned below the opening 11b. The screw shaft 13d is positioned with its longitudinal direction facing horizontally (front-to-back). The screw shaft 13d can be rotated by a driving force from a driving source (not shown) such as a motor. The nut 13c is fitted onto the screw shaft 13d. A number of balls (not shown) are interposed between the nut 13c and the screw shaft 13d. The lower end of the connecting portion 13b is fixed to the upper part of the nut 13c. Rotation of the nut 13c around the screw shaft 13d is prevented.

The cover member 13e shown in Figure 6 covers the moving member 13a from the side. The cover member 13e is formed by combining multiple plate-shaped members. Specifically, the cover member 13e is configured to surround the moving member 13a from the front, back, left, and right using a pair of plate-shaped members at the front and back and a pair of plate-shaped members at the left and right. The cover member 13e is fixed to the moving member 13a in an appropriate manner. Note that the cover member 13e is not shown in figures other than Figure 6.

In the movement mechanism 13, when the screw shaft 13d rotates, the nut 13c fitted to the screw shaft 13d moves linearly in a direction (either forward or backward) corresponding to the rotation direction of the screw shaft 13d. When the nut 13c moves, the moving member 13a connected to the nut 13c via the connecting portion 13b also moves linearly together with the nut 13c.

The second receiving member 14 shown in Figures 2 and 3 is a member that receives scraps E generated when cutting the sealed substrate W. The second receiving member 14 is formed in a box shape that is open upward and backward. The second receiving member 14 is fixed to the upper part of the moving member 13a. The second receiving member 14 can receive scraps E that fall from the cutting table 15.

The cutting table 15 is the portion on which the sealed substrate W, which is the object to be cut, is placed. The cutting table 15 is one embodiment of the processing table of the present application. The cutting table 15 is placed above the first receiving member 11 and the second receiving member 14. The cutting table 15 is supported by the moving member 13a via the rotation mechanism 17, which will be described later.

The rotation mechanism 17 rotates the cutting table 15 in the θ direction. The rotation mechanism 17 is interposed between the moving member 13a and the cutting table 15. The rotation mechanism 17 can rotate the cutting table 15 using a driving force from a driving source (not shown) such as a motor.

The rear cover member 18 shown in Figures 3 and 5 covers the opening 11b from above behind the movable member 13a. The rear cover member 18 is positioned above the protrusion 11a. The rear cover member 18 is bellows-shaped and is configured to be able to expand and contract in the front-to-rear direction. The front of the rear cover member 18 is connected to the movable member 13a. As a result, the rear cover member 18 expands and contracts in the front-to-rear direction in conjunction with the movement of the movable member 13a in the front-to-rear direction.

The front cover member 19 shown in Figures 2, 3, and 5 covers the opening 11b from above in front of the movable member 13a. The front cover member 19 is positioned above the protrusion 11a. The front cover member 19 is bellows-shaped and is configured to be able to expand and contract in the front-to-rear direction. The rear of the front cover member 19 is connected to the movable member 13a. This allows the front cover member 19 to expand and contract in the front-to-rear direction as the movable member 13a moves in the front-to-rear direction.

The upper cover member 20 covers the rear cover member 18 from above. The upper cover member 20 mainly comprises multiple plate-shaped members 20a and connecting portions 20b.

The multiple plate-shaped members 20a are formed in the shape of rectangular plates. The multiple plate-shaped members 20a are arranged in a line in the front-to-rear direction above the upper cover member 20. The multiple plate-shaped members 20a are arranged so that at least a portion of each plate-shaped member 20a overlaps in the vertical direction with adjacent plate-shaped members 20a in the front-to-rear direction. Adjacent plate-shaped members 20a are connected to each other so that they can move relative to each other. The multiple plate-shaped members 20a are arranged to span both the front and rear ends of the rear cover member 18. The rear end of the rearmost plate-shaped member 20a is arranged so as to overlap in the vertical direction with the storage section 12.

The connecting portion 20b connects the plate-shaped member 20a to the second receiving member 14. The connecting portion 20b is fixed to the bottom surface of the rear end of the second receiving member 14. The connecting portion 20b is connected to the plate-shaped member 20a located at the front most position. This allows the multiple plate-shaped members 20a to expand and contract in the front-to-rear direction as the second receiving member 14 (moving member 13a) moves in the front-to-rear direction.

The cleaning nozzle 22 shown in Figures 2 to 4 sprays cleaning water into the inclined groove portion 11c. The cleaning nozzle 22 is positioned above the front of the inclined groove portion 11c, facing rearward. The cleaning nozzle 22 can spray cleaning water from its tip (rear end). The cleaning water sprayed from the cleaning nozzle 22 can wash away scrap material E from the inclined groove portion 11c and wash away dirt such as cutting chips.

The spindle unit 23 shown in Figures 2 and 3 is used to cut the sealed substrate W, which is the object to be cut. The spindle unit 23 is one embodiment of the cutting mechanism of the present application. A blade 23a that rotates in a plane including the front-to-back and up-to-down directions is attached to the spindle unit 23. A cutting nozzle 23b is provided near the spindle unit 23 to supply cutting water when cutting the sealed substrate W. The cutting nozzle 23b can move integrally with the spindle unit 23.

The removal mechanism 26 shown in Figures 2 and 3 is used to discharge scrap material E from the first receiving member 11 (inclined groove portion 11c) into the storage section 12. The removal mechanism 26 is provided on both the left and right sides of the moving member 13a.

The removal mechanisms 26 provided on the left and right sides of the movable member 13a are symmetrical in configuration, and therefore the following description will focus on the removal mechanism 26 located on the left side of the movable member 13a. For convenience, the removal mechanism 26 is shown in simplified form in all figures except for Figures 6 and 7, and therefore the following description will use Figures 6 and 7 to describe the configuration of the removal mechanism 26.

As shown in Figures 6 and 7, the removal mechanism 26 mainly comprises a position adjustment mechanism 30 and a movable nozzle 40.

The position adjustment mechanism 30 supports the movable nozzle 40 and adjusts the vertical position of the movable nozzle 40. The position adjustment mechanism 30 mainly comprises a shaft 31, a fixed portion 32, a lifting block 33, a linear bushing 34, a bracket 35, and a roller 36.

The shaft 31 is used to guide the lifting block 33 up and down. The shaft 31 is formed in a roughly cylindrical shape. The upper part of the shaft 31 is formed in a flat plate shape to make it easier to fix the fixing part 32. The shaft 31 is arranged with its axis facing up and down. Two shafts 31 are provided, lined up front and back. The two shafts 31 are arranged parallel to each other. Note that, for simplicity, only one shaft 31 is shown in figures other than Figures 6 and 7.

The fixing portion 32 is used to fix the shaft 31 to the cover member 13e. The fixing portion 32 is formed in a rod shape. The fixing portion 32 is arranged with its axis oriented in the left-right direction. Two fixing portions 32 are provided for one shaft 31. One end (left end) of the fixing portion 32 is fixed to the top of the shaft 31. The other end (right end) of the fixing portion 32 is fixed to the left side surface of the cover member 13e. This allows the fixing portion 32 to fix the shaft 31 to the left side surface of the cover member 13e.

The lifting block 33 supports the movable nozzle 40 so that it can be raised and lowered. The lifting block 33 is one embodiment of the lifting unit of the present application. The lifting block 33 is formed in an appropriate shape to which the bracket 35, movable nozzle 40, etc. can be attached.

The linear bushing 34 shown in Figure 7 allows the lifting block 33 to move up and down smoothly along the shaft 31. The linear bushing 34 is formed in a roughly cylindrical shape. Balls or the like are provided in the linear bushing 34 to reduce resistance with the shaft 31. The linear bushings 34 are fixed in two through holes (not shown) that pass through the lifting block 33 from top to bottom. A shaft 31 is inserted into each of the two linear bushings 34. This allows the lifting block 33 to move up and down along the shaft 31. Furthermore, inserting two shafts 31 into the lifting block 33 prevents the lifting block 33 from rotating around the axis of the shaft 31.

The bracket 35 shown in Figures 6 and 7 is used to support the roller 36. The bracket 35 is formed in a generally rectangular plate shape. The bracket 35 is positioned with its longitudinal direction facing up and down. The upper part of the bracket 35 is fixed to the left side of the lifting block 33. As a result, the bracket 35 is positioned to extend downward from the lifting block 33.

The roller 36 is the portion that comes into contact with the inclined groove portion 11c of the first receiving member 11. The roller 36 is one embodiment of the contact portion of the present application. The roller 36 is formed in a generally cylindrical shape. The roller 36 is positioned with its axis, which is the center of rotation, facing left and right. The roller 36 is rotatably supported at the bottom of the bracket 35.

The movable nozzle 40 moves together with the movable member 13a and sprays cleaning water into the inclined groove portion 11c. The movable nozzle 40 is a two-fluid nozzle that can mix and spray two types of fluid (e.g., air and cleaning water). The movable nozzle 40 is fixed to the lifting block 33 via a connecting portion 41. The movable nozzle 40 is positioned with its tip facing rearward and downward. The movable nozzle 40 can spray fluid rearward and downward from its tip. The fluid sprayed from the movable nozzle 40 is supplied to the movable nozzle 40 via a flow path formed inside the connecting portion 41 and the lifting block 33, as well as a hose or the like (not shown).

In the removal mechanism 26 configured as described above, the lifting block 33 descends along the shaft 31 due to its own weight. Furthermore, the roller 36 comes into contact with the inclined groove portion 11c, thereby restricting the descent of the lifting block 33.

The removal mechanisms 26 are provided on both the left and right sides of the moving member 13a, and are positioned to correspond to the three inclined groove portions 11c, as shown in Figure 2.

<Discharge of Scrap E>
Hereinafter, with reference to FIGS. 3 and 8, a description will be given of how the scrap material E that has fallen into the inclined groove portion 11c is discharged in the cutting device 100 configured as described above.

When cutting the sealed substrate W, the moving member 13a can be moved back and forth by rotating the screw shaft 13d of the moving mechanism 13, and as a result, the cutting table 15 can be moved in the front-to-back direction. By combining the front-to-back movement of the cutting table 15 by the moving mechanism 13, the rotation of the cutting table 15 in the θ direction by the rotation mechanism 17, and the left-to-right and up-to-down movement of the spindle portion 23, the sealed substrate W placed on the cutting table 15 can be cut into individual pieces by the blade 23a.

Scraps E and cutting debris generated when cutting a sealed substrate W may fall from the cutting table 15 into the inclined groove 11c of the first receiving member 11. When cutting a sealed substrate W in the cutting device 100, cleaning water is sprayed continuously or intermittently from the cleaning nozzle 22. This cleaning water can wash away scraps E and cutting debris that have fallen into the inclined groove 11c toward the storage section 12.

Furthermore, in this embodiment, the removal mechanism 26 can more reliably discharge scraps E and the like that have fallen into the inclined groove portion 11c into the storage portion 12. Specifically, as shown in FIG. 3, fluid is sprayed downward and rearward from the movable nozzle 40 of the removal mechanism 26, which is provided on the side of the moving member 13a. In this way, the fluid sprayed from the movable nozzle 40, in addition to the cleaning water sprayed from the cleaning nozzle 22, can more reliably wash scraps E and the like that have fallen into the inclined groove portion 11c toward the storage portion 12.

Furthermore, for example, when the movable member 13a moves rearward, the removal mechanism 26 also moves rearward together with the movable member 13a, as shown in Figure 8. At this time, the roller 36 in contact with the inclined groove portion 11c descends while rolling on the inclined groove portion 11c. As a result, the lifting block 33 descends to follow the inclined groove portion 11c.

Although not shown in the figure, when the movable member 13a moves forward, the roller 36 rises while rolling on the inclined groove portion 11c, and the lifting block 33 rises to follow the inclined groove portion 11c.

In this way, the lifting block 33 moves up and down in accordance with the inclined groove portion 11c, allowing the vertical position of the movable nozzle 40 to be adjusted. In particular, in this embodiment, the vertical position of the movable nozzle 40 can be adjusted so that the distance between the movable nozzle 40 and the inclined groove portion 11c remains constant, regardless of the movement of the movable member 13a. This allows the water pressure of the fluid sprayed into the inclined groove portion 11c to be kept roughly constant, effectively washing away scraps E and other materials that have fallen into the inclined groove portion 11c.

The above describes the first embodiment of the present invention, but the present invention is not limited to the above embodiment and can be modified as appropriate within the scope of the technical concept of the invention described in the claims.

For example, the configuration (shape, arrangement, number, etc.) of each part of the cutting device 100 described in this embodiment is not particularly limited and can be changed as desired.

Furthermore, the configuration of the position adjustment mechanism 30 shown in this embodiment is an example, and the present invention is not limited to this.

Specifically, in this embodiment, the lifting block 33 (movable nozzle 40) descends under its own weight, but the present invention is not limited to this. For example, it is also possible to configure the lifting block 33 to be pushed downward by a spring or the like. This makes it easier for the roller 36 to follow the inclined groove portion 11c.

In addition, in this embodiment, the roller 36 is brought into contact with the inclined groove 11c to raise and lower the movable nozzle 40 along the inclined groove 11c, but the present invention is not limited to this. For example, instead of the inclined groove 11c, the roller 36 can be brought into contact with a separately provided guide member such as a rail to raise and lower the movable nozzle 40.

The lifting block 33 can also be raised and lowered using the power of an appropriate drive source. For example, the lifting block 33 can be configured to be raised and lowered using the power of a motor, cylinder, or the like. In this case, it is desirable to control the vertical position of the lifting block 33 according to the front-to-rear position of the cutting table 15, thereby controlling the movable nozzle 40 to an appropriate height.

In addition, while this embodiment shows an example in which the vertical position of the movable nozzle 40 is adjusted so that the distance between the movable nozzle 40 and the inclined groove portion 11c is constant, the present invention is not limited to this. In other words, the distance between the movable nozzle 40 and the inclined groove portion 11c does not necessarily have to be constant. For example, it is possible to adjust the vertical position of the movable nozzle 40 so that the distance between the movable nozzle 40 and the inclined groove portion 11c becomes smaller as the movable nozzle 40 moves further rearward (towards the storage portion 12). This allows the water pressure of the fluid sprayed against the scrap E to be stronger the more downstream (rearward) the inclined groove portion 11c is where more scrap E is present, allowing the scrap E to be discharged more reliably.

In addition, while this embodiment shows an example in which the roller 36 comes into contact with the inclined groove portion 11c, the present invention is not limited to this, and any member can be brought into contact with the inclined groove portion 11c. In this case, it is preferable to use a low-friction material that has relatively little friction with the inclined groove portion 11c, from the perspective of suppressing damage to the member and suppressing resistance.

In addition, while this embodiment illustrates an example in which the removal mechanism 26 is fixed to the cover member 13e, the present invention is not limited to this. The removal mechanism 26 can also be provided on other members that move in conjunction with the movement of the cutting table 15. For example, the removal mechanism 26 can also be provided on the moving member 13a, the second receiving member 14, the connecting portion 13b, etc.

In addition, while this embodiment shows an example in which two shafts 31 are used to guide the lifting block 33 up and down, the present invention is not limited to this, and the number of shafts 31 can be changed as desired. If only one shaft 31 is used, it is desirable to provide a mechanism to prevent the lifting block 33 from rotating around the axis of the shaft 31. For example, it is possible to prevent the lifting block 33 from rotating by forming splines on the shaft 31 and the lifting block 33 (linear bushing 34).
