[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that each of the embodiments described below represents a specific example of the present invention. Therefore, the numerical values, shapes, materials, components, component arrangements and connection forms, steps, and step sequences shown in the following embodiments are merely examples and are not intended to limit the present invention. Therefore, among the components in the following embodiments, components that are not recited in the independent claims of the present invention will be described as optional components.

[0010] Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration. Therefore, for example, the scales of the figures do not necessarily match. Furthermore, in each figure, substantially the same components are given the same reference numerals, and redundant explanations are omitted or simplified.

[0011] In this specification and drawings, the X-axis, Y-axis, and Z-axis represent the three axes of a three-dimensional Cartesian coordinate system. The X-axis and Y-axis are perpendicular to each other and perpendicular to the Z-axis. In the following embodiments, the positive direction of the Z-axis may be referred to as the upward direction, and the negative direction of the Z-axis may be referred to as the downward direction.

[0012] (Embodiment) [composition] First, the configuration of the component crimping device according to the embodiment will be described.

[0013] Fig. 1 is a block diagram showing a component crimping device 100 according to an embodiment. Fig. 2 is a perspective view showing a specific configuration of a thermocompression bonding mechanism 200 according to an embodiment. Fig. 3 is a side view showing a specific configuration of the thermocompression bonding mechanism 200 according to an embodiment.

[0014] The component bonding apparatus 100 is an apparatus that bonds (more specifically, thermocompression bonds) components 3 to a substrate 2. The component bonding apparatus 100 is part of a component mounting system for producing, for example, display panels. In the component mounting system, for example, an anisotropic conductive film such as ACF is attached to electrode portions provided on the substrate 2, the components 3 are placed (pre-bonded) on the substrate 2 via the anisotropic conductive film, and the pre-bonded substrate 2 and components 3 are thermocompression bonded together. The mounting system includes, for example, an attachment apparatus that bonds the anisotropic conductive film to the substrate 2, a pre-bonding apparatus that places (pre-bonds) the components 3 on the substrate 2 via the anisotropic conductive film, and a final bonding apparatus that thermocompression bonds (final bonding) the components 3 to the substrate 2. For example, the component bonding apparatus 100 is a final bonding apparatus included in the mounting system.

[0015] The component pressure-bonding device 100 performs final pressure-bonding between a substrate 2 and a component 3, which are carried out from an upstream device (e.g., a pre-pressure bonding device) to the substrate placement unit 12a by, for example, a substrate transport device (not shown). The substrate 2 to which the component 3 has been final pressure-bonded is then transported by, for example, the substrate transport device to a downstream device (e.g., an unloader).

[0016] The substrate 2 may be, for example, a flexible substrate made of resin, etc. The substrate 2 may also be a display panel using a glass substrate, etc.

[0017] Examples of the component 3 include flexible components such as TCP (Tape Carrier Package) and FPC (Flexible Printed Circuits), or IC (Integrated Circuit) chips.

[0018] The component bonding apparatus 100 includes a thermocompression bonding mechanism 200 and a control device 300.

[0019] The thermocompression bonding mechanism 200 is a mechanical unit that thermocompresses the substrate 2 and the component 3 together. For example, the thermocompression bonding mechanism 200 is controlled by the control device 300 (specifically, the control unit 310) to thermocompression bond the component 3 to the substrate 2. In this embodiment, the thermocompression bonding mechanism 200 includes a base 11, a substrate positioning unit 12, a gate-shaped frame 13, a backup stage 14, a touch panel 16, a compression bonding unit 21, a protective sheet supply unit 22, a unit support unit 23, and an alignment camera 50. The substrate positioning unit 12 includes a substrate placement unit 12a and a movement mechanism 12b. The compression bonding unit 21 includes an elevation motor 31, an elevation base 32, a compression bonding tool 33, a pressure cylinder 34, and a heater 35.

[0020] The thermocompression bonding mechanism 200 has a substrate positioning unit 12 on the negative Y-axis side of a base 11, and a gate-shaped frame 13 and a backup stage 14 on the positive Y-axis side of the substrate positioning unit 12. An alignment camera 50 is also disposed on the base 11 for locating the position of the substrate 2 at a predetermined position. A touch panel 16 is disposed on the negative Y-axis side of the base 11 as an input / output device used by an operator.

[0021] The substrate positioning unit 12 is a mechanism for positioning the substrate 2 on which components 3 have been pre-mounted at a predetermined position, and is equipped with a substrate mounting unit 12a that holds the substrate 2 in a horizontal position, and a moving mechanism 12b that moves the substrate mounting unit 12a in three dimensions while maintaining the horizontal position.

[0022] The substrate placement portion 12a is a stage (table) on which the substrate 2 on which a plurality of components 3 are mounted (arranged) is placed. Specifically, the substrate 2 on which the components 3 are arranged via an anisotropic conductive film is placed on the substrate placement portion 12a. For example, the substrate 2 transported by the above-described substrate transport device is placed on the substrate placement portion 12a in a state in which the end portion on which the components 3 are mounted protrudes. In this manner, the substrate placement portion 12a has a holding surface on which the substrate 2 is placed in a state in which the end portion, which is the outer edge of the substrate 2, protrudes from the substrate placement portion 12a (more specifically, in a state in which the end portion does not overlap with the substrate placement portion 12a in a top view). The end portion of the substrate 2 is supported by the backup stage 14 when the components 3 are pressure-bonded to the substrate 2.

[0023] The substrate mounting portion 12a may be provided with a suction mechanism that suctions the substrate 2 onto the holding surface. For example, an opening (e.g., a through-hole) is formed in the holding surface, and the substrate mounting portion 12a suctions and holds the substrate 2 on the holding surface. For example, a suction device that sucks air through the opening to suck the substrate 2 onto the holding surface may be connected to the opening, and the suction device may suck the air, thereby suctioning and holding the substrate 2 on the holding surface. The suction mechanism may have, for example, a vacuum pump that sucks air, a vacuum pipe connecting the vacuum pump and the opening, and a valve for controlling suction.

[0024] The control unit 310, which will be described later, controls the valve to switch whether or not the suction mechanism generates a suction force on the holding surface, that is, whether or not the suction mechanism suctions the edge of the substrate 2.

[0025] The valve provided in the suction mechanism may be, for example, a solenoid valve for switching on and off the suction of air, or a pressure adjustment valve (so-called pressure regulator) for switching the suction force (adsorption force).

[0026] Alternatively, the substrate placement portion 12a may not have the above-described opening or the like on the holding surface, and the substrate 2 may be simply placed on the holding surface 111, thereby holding the substrate 2 on the holding surface.

[0027] The substrate placement portion 12a is provided so as to be movable by, for example, a movement mechanism 12b.

[0028] The moving mechanism 12b is a mechanism for moving the substrate mounting part 12a. For example, the substrate mounting part 12a and the moving mechanism 12b form a three-axis stage. The moving mechanism 12b is realized by, for example, a conveyor configured to be able to move the substrate mounting part 12a arbitrarily on the XY plane and to be able to move up and down in the Z-axis direction.

[0029] The moving mechanism 12b moves the substrate placement portion 12a on which the substrate 2 is placed, thereby moving the end of the substrate 2 above (more specifically, directly above) the backup stage .

[0030] The portal frame 13 has a horizontal section 13a that extends in the X-axis direction above the center of the base 11. A crimping section 21 is provided on the underside of the horizontal section 13a. The backup stage 14 is provided below the crimping section 21 and extends in the X-axis direction. A supply device 600 provided in the protective sheet supply section 22 is provided between the crimping section 21 and the backup stage 14. The supply device 600 is configured to be detachably installed on a unit support section 23 provided on the base 11.

[0031] The crimping unit 21 includes a lifting base 32 that moves up and down by the operation of a lifting motor 31. The lifting base 32 is provided with a plurality of crimping tools 33. In this embodiment, the crimping unit 21 includes six crimping tools 33.

[0032] The multiple crimping tools 33 perform a pressing operation of pressing each of the multiple components 3 toward the substrate 2 via the protective sheet 43, i.e., perform a crimping operation of crimping the components 3 onto the substrate 2. The crimping tools 33 are arranged side by side in the X-axis direction. Each crimping tool 33 is positioned directly above the backup stage 14 and is individually raised and lowered by a pressure cylinder 34 provided corresponding to each crimping tool 33. Each crimping tool 33 has a built-in heater 35.

[0033] The heater 35 is a heater for heating the crimping tool 33. The crimping tool 33 is heated by the heater 35, and the crimping tool 33 presses the component 3 against the substrate 2, thereby thermocompression-bonding the component 3 to the substrate 2. The heater 35 is realized by, for example, a heating wire or a Peltier element.

[0034] The protective sheet supply unit 22 is a mechanism that supplies the protective sheet 43 between the crimping tool 33 and the component 3. The protective sheet supply unit 22 includes a supply device 600 and a release device 700.

[0035] FIG. 4 is a perspective view showing a specific configuration of the supply device 600 according to the embodiment.

[0036] The supply device 600 includes a case 41 , a plurality of supply reels 42 , a guide roller 44 , a feed roller 45 , a drive motor 47 , a plurality of pressing mechanisms 400 , and a block support portion 610 .

[0037] Supply device 600 has a case 41 that forms an outer shell and includes a plurality of supply reels 42 (six in this embodiment, corresponding to the number of crimping tools 33). Each supply reel 42 holds a protective sheet 43 in a rolled state, and is provided inside case 41, lined up in the X-axis direction with its rotation axis facing the X-axis direction. A plurality of guide rollers 44 are provided at the center of case 41 in the Y-axis direction. Also, one feed roller 45 and a plurality of (six in this embodiment, corresponding to the number of supply reels 42) presser mechanisms 400 are provided on the positive Y-axis side inside case 41.

[0038] The guide rollers 44 guide the protective sheet 43 pulled out in the positive direction of the Y axis from each supply reel 42 so that the protective sheet 43 assumes a substantially horizontal position in the center of the case 41. The central portion located directly below the crimping tool 33 is the portion where the crimping tool 33 presses the component 3 via the protective sheet 43 when the crimping tool 33 presses the component 3, as will be described later.

[0039] The feed roller 45 collectively feeds the multiple protective sheets 43 that have been pulled out from the multiple supply reels 42. The feed roller 45 is in contact with each of the multiple protective sheets 43, and is rotated (turned) by the drive motor 47 to feed the multiple protective sheets 43. In this embodiment, the action of the feed roller 45 rotating while in contact with each of the multiple protective sheets 43 is referred to as the feed action. Due to a release mechanism 500, which will be described later, there are cases in which the protective sheets 43 do not move even when the feed roller 45 performs the feed action. Specific examples will be described later.

[0040] The feed roller 45 is arranged with its rotation axis facing the X-axis direction, and is in contact with a portion of the protective sheet 43 that is further toward the Y-axis positive side than the guide roller 44, which is located furthest toward the Y-axis positive side.

[0041] Each of the plurality of pressure mechanisms 400 includes a pressure roller 410 , a biasing spring 420 , a biasing spring support portion 430 , a pressure roller block 440 , and a connecting portion 450 .

[0042] The pressure roller 410 is a pinch roller that pinches the protective sheet 43 together with the feed roller 45. The multiple pressure rollers 410 (six pressure rollers 410 in this embodiment) press each of the multiple protective sheets 43 (six protective sheets 43 in this embodiment) against the feed roller 45. The six pressure rollers 410 are arranged on the positive Y-axis side of the feed roller 45 and are lined up in the X-axis direction with their rotation axes facing the X-axis direction. Each pressure roller 410 is biased in the positive Y-axis direction by a biasing spring 420, thereby pressing the protective sheet 43 against the feed roller 45 and bringing it into close contact with it.

[0043] The biasing spring 420 is an elastic body for pressing the pressure roller 410 against the feed roller 45 via the protective sheet 43. One end of the biasing spring 420 is attached to a member that rotatably supports the pressure roller 410, and the other end is attached to the pressure roller block 440.

[0044] The biasing spring support portion 430 is a support that supports the biasing spring 420. The biasing spring support portion 430 is fixed to a block support portion 610 attached to the case 41. As a result, the biasing spring 420 presses the pressure roller 410 against the feed roller 45.

[0045] The pressure roller block 440 is a member connected to the pressure roller 410 via a connection portion 450 .

[0046] One end of connecting portion 450 is attached to a member that rotatably supports pressure roller 410, and the other end is attached movably to pressure roller block 440. In this embodiment, connecting portion 450 is movable in the Y-axis direction.

[0047] The pressure roller 410, the pressure roller block 440, and the connection portion 450 are attached to the biasing spring support portion 430 so as to be movable in the Y-axis direction.

[0048] A drive motor 47 is provided outside the case 41 as roller drive means for driving and rotating the feed roller 45. When the drive motor 47 drives and rotates the feed roller 45 around the X axis (arrow A in FIG. 3), the protective sheet 43 is pulled in the positive direction of the Y axis by the feed roller 45, pulled out from the supply reel 42, and fed in the positive direction of the Y axis. After passing the feed roller 45, the protective sheet 43 is guided below the feed roller 45 and discharged below the case 41 without being taken up by the feed roller 45.

[0049] Here, when the pressure roller block 440 is moved in the positive direction of the Y axis by the release device 700 (specifically, the release mechanism 500), the pressure roller 410, which is connected to the pressure roller block 440 via the connection part 450 and the like, is also moved in the positive direction of the Y axis. As a result, the feed roller 45 and the pressure roller 410 are no longer in contact with each other. Therefore, the protective sheet 43 is no longer sandwiched between the feed roller 45 and the pressure roller 410, and is no longer fed in the positive direction of the Y axis even when the feed roller 45 rotates. In other words, the protective sheet 43 is no longer fed.

[0050] The release device 700 is a device for controlling the supply of the protective sheets 43. Specifically, the release device 700 is a device for switching whether or not to supply each of the multiple protective sheets 43 (six protective sheets 43 in this embodiment) stored in the supply device 600. The release device 700 includes multiple release mechanisms 500 and an outer housing 710.

[0051] The releasing device 700 includes a plurality of releasing mechanisms 500 (six in this embodiment, corresponding to the number of crimping tools 33) inside an outer casing 710 that forms the outer shell.

[0052] The multiple release mechanisms 500 are mechanisms that release the multiple pressure rollers 410 from pressing against the respective feed rollers 45. Each of the multiple release mechanisms 500 includes a release lever drive unit 510, a rotating unit 520, a release lever 530, and a lever spring 540.

[0053] The release lever driving unit 510 is a device for driving (specifically, rotating) the release lever 530. The release lever driving unit 510 is configured by a cylinder for rotating the release lever 530, for example.

[0054] The rotating part 520 is a support member that rotatably supports the release lever 530. The rotating part 520 is attached to the outer casing 710, for example, and supports the release lever 530.

[0055] The release lever 530 is a lever rotatably supported by the rotating unit 520. The release lever 530 is, for example, a long member, the center of which is supported by the rotating unit 520, and one end of which is moved by the release lever driving unit 510 to rotate. When one end of the release lever 530 is moved by the release lever driving unit 510 to rotate, the other end moves the pressure roller block 440. As a result, the feed roller 45 and the pressure roller 410 no longer come into contact with each other, and the protective sheet 43 is no longer fed. The other end of the release lever 530 is attached to a lever spring 540.

[0056] Lever spring 540 is an elastic body that rotates release lever 530. For example, one end of lever spring 540 is attached to release lever 530, and the other end is attached to outer casing 710. Lever spring 540 is attached to release lever 530 and outer casing 710, for example, so as to pull the other end of release lever 530 toward outer casing 710. In the present embodiment, lever spring 540 pulls the other end of release lever 530 in a direction that rotates the other end of release lever 530 clockwise around pivot unit 520 when viewed in the YZ plane. As a result, lever spring 540 rotates the other end of release lever 530 clockwise around pivot unit 520, for example, when a piston that is provided in release lever drive unit 510 and that has been pressing one end of release lever 530 is moved in the positive direction of the Y axis.

[0057] 5A and 5B are diagrams illustrating a specific example of the operation of the release mechanism 500 according to the embodiment. Specifically, (a) of Fig. 5 shows a state in which the pressure roller 410 presses the protective sheet 43 against the feed roller 45, and (b) of Fig. 5 shows a state in which the pressure roller 410 does not press the protective sheet 43 against the feed roller 45.

[0058] In the state (a) of Figure 5 (also called release OFF), the pressure roller 410 is pressing the protective sheet 43 against the feed roller 45, so when the feed roller 45 is rotated by the drive motor 47, the pressure roller 410 also rotates, and the protective sheet 43 sandwiched between the feed roller 45 and the pressure roller 410 moves.

[0059] On the other hand, in the state shown in (b) of Figure 5 (also called release ON), the pressure roller 410 is not pressing the protective sheet 43 against the feed roller 45, so even if the feed roller 45 is rotated by the drive motor 47, the pressure roller 410 does not rotate, and the feed roller 45 rotates freely, so that the protective sheet 43 that is not sandwiched between the feed roller 45 and the pressure roller 410 does not move.

[0060] To switch the release mechanism 500 from the release-off state to the release-on state, for example, the control unit 310 controls the release lever drive unit 510 to cause a piston included in the release lever drive unit 510 to push and rotate one end of the release lever 530 in the negative direction of the Y axis. This moves the pressure roller block 440 in the positive direction of the Y axis, and the pressure roller 410 also moves in the positive direction of the Y axis. This switches the release mechanism 500 to the release-on state, and the protective sheet 43 will not be fed even if the feed roller 45 is rotated.

[0061] Furthermore, to switch the release mechanism 500 from the release-ON state to the release-OFF state, for example, the control unit 310 controls the release lever drive unit 510 to move a piston included in the release lever drive unit 510 in the positive direction of the Y axis. As a result, the release lever 530 is rotated by the lever spring 540, and the other end of the release lever 530 is moved in the negative direction of the Y axis. In addition, the pressure roller 410 is also moved in the negative direction of the Y axis by the biasing spring 420. As a result, the release mechanism 500 is switched to the release-OFF state, and when the feed roller 45 is rotated, the protective sheet 43 is fed.

[0062] In the thermocompression bonding operation of the component 3 by the thermocompression bonding mechanism 200, first, the drive motor 47 controlled by the control unit 310 rotates the feed roller 45 so that the portion of the protective sheet 43 pulled out from each supply reel 42 and pressed by the crimping tool 33 becomes an unused portion. Here, the control unit 310, for example, first controls the release mechanism 500 to move the pressure roller 410 that presses the protective sheet 43 against the feed roller 45 corresponding to a crimping tool 33 (also referred to as an idle tool) among the multiple crimping tools 33 that is not used for crimping the component 3 to the substrate 2, thereby setting the release mechanism 500 to a release-OFF state. Thereafter, the control unit 310 controls, for example, the drive motor 47 to rotate the feed roller 45. As a result, the unused portion of the protective sheet 43 is supplied to a position corresponding to the crimping tool 33 (also referred to as an active tool) among the multiple crimping tools 33 that is used for crimping the component 3 to the substrate 2, and the unused portion of the protective sheet 43 is not supplied to a position corresponding to the idle tool.

[0063] Next, the lift motor 31 controlled by the control unit 310 is operated to lift the lift base 32, and each crimping tool 33 is positioned at its initial position above the protective sheet 43. Once each crimping tool 33 is positioned at its initial position, the control unit 310 moves the substrate mounting unit 12a holding the substrate 2 using the movement mechanism 12b, and positions the substrate 2 so that the components 3 previously mounted on the substrate 2 via the anisotropic conductive film are located below the corresponding crimping tool 33 (in other words, above the backup stage 14).

[0064] Once the substrate 2 is positioned, the control unit 310 controls the pressure cylinder 34 to cause the pressure cylinder 34 to press down the tool to be used among the multiple bonding tools 33 from its initial position. As a result, the tool to be used descends from above the protective sheet 43 and presses the component 3 together with the protective sheet 43 onto the substrate 2. During this pressing, the component 3 is pressed together with the substrate 2 against the backup stage 14, and the anisotropic conductive film is heated through the component 3 by a heater 35 built into the bonding tool 33. As a result, the component 3 is thermocompression bonded (mainly bonded) to the substrate 2. When the bonding tool 33 presses the component 3 onto the substrate 2, the protective sheet 43 is interposed between the bonding tool 33 and the component 3, so the bonding tool 33 does not come into contact with the anisotropic conductive film, and no part of the anisotropic conductive film adheres to the bonding tool 33.

[0065] When the component 3 is pressed against the substrate 2 by the crimping tool 33, the control unit 310 controls the pressure cylinder 34 to raise the crimping tool 33 (specifically, the tool to be used) and return it to its initial position. Then, once the crimping tool 33 is positioned at its initial position, the control unit 310 controls the drive motor 47 to rotate the feed roller 45 and pull out a predetermined amount (length) of the protective sheet 43 from the supply reel 42, thereby performing a renewal operation for the protective sheet 43. In the renewal operation, the control unit 310 controls the protective sheet supply unit 22 to feed only a portion of the protective sheet 43 corresponding to the tool to be used in the next crimping operation in the positive direction of the Y axis, and rotates the feed roller 45 by a predetermined rotation angle so that the unused portion of the protective sheet 43 becomes the new pressing portion. After the renewal operation for the protective sheet 43 is completed, the positioning of the substrate 2 and the pressing of the component 3 by the crimping tool 33 are repeatedly performed as described above.

[0066] The control device 300 is a computer that controls mechanisms such as the moving mechanism 12b, the pressure bonding unit 21, and the protective sheet supply unit 22 that the thermocompression bonding mechanism 200 includes.

[0067] The control device 300 is realized by a communication interface for communicating with mechanisms such as the moving mechanism 12b, the compression unit 21, and the protective sheet supply unit 22 included in the thermocompression bonding mechanism 200, a nonvolatile memory storing a program, a volatile memory that is a temporary storage area for executing the program, an input / output port for transmitting and receiving signals, and a processor that executes the program. The communication interface may be realized, for example, by an antenna and a wireless communication circuit that enables wireless communication, or by a connector to which a communication line is connected that enables wired communication.

[0068] The control device 300 includes a control unit 310 and a storage unit 320 .

[0069] The control unit 310 is a processing unit that controls the protective sheet supply unit 22 and the multiple crimping tools 33. Specifically, the control unit 310 controls mechanisms such as the moving mechanism 12b, the crimping unit 21, and the protective sheet supply unit 22 included in the thermocompression bonding mechanism 200. For example, the control unit 310 controls the drive motor 47 and the release lever drive unit 510 included in the protective sheet supply unit 22 to control the movement of the protective sheet 43. Furthermore, for example, the control unit 310 controls the lifting motor 31 and the pressure cylinder 34 to individually control the lifting and lowering of the multiple crimping tools 33. The control unit 310 includes, for example, a processor such as a CPU (Central Processing Unit) and a memory that stores a control program executed by the processor.

[0070] For example, the control unit 310 controls the substrate transport device to place the substrate 2, on which multiple components 3 are mounted, on the substrate placement unit 12a. Next, the control unit 310 controls the movement mechanism 12b to cause the movement mechanism 12b to move the substrate placement unit 12a. For example, the control unit 310 controls the movement mechanism 12b based on the image capture result of the alignment camera 50 to place the edge of the substrate 2 on the backup stage 14. Furthermore, the control unit 310 controls the protection sheet supply unit 22 to supply the protection sheet 43 between the components 3 and the crimping tool 33. Specifically, the control unit 310 controls the protection sheet supply unit 22 to supply an unused region of the protection sheet 43 between the components 3 and the crimping tool 33. The unused region is a region (portion) of the protection sheet 43 that has not yet been pressed by the crimping tool 33.

[0071] Here, the control unit 310 controls the multiple release mechanisms 500 to control the supply of each of the multiple protective sheets 43. Specifically, the control unit 310 controls the multiple release mechanisms 500 to control whether or not to supply each of the multiple protective sheets 43. For example, when a crimping tool presses a component 3 against a substrate 2, if there is a paused tool among the multiple crimping tools 33 that is not performing a pressing operation, the control unit 310 controls the release mechanism 500 corresponding to the paused tool among the multiple release mechanisms 500 to release the pressure roller 410 corresponding to the paused tool from pressing against the feed roller 45, thereby stopping the supply of the protective sheet 43 to the position corresponding to the paused tool. For example, if the number of crimping tools 33 included in the component crimping apparatus 100 is greater than the number of components 3 to be collectively pressed against the substrate 2, there will be one or more paused tools among the multiple crimping tools 33. Furthermore, the control unit 310 causes the pressure bonding tool 33 to press the component 3 via the protective sheet 43, thereby causing the pressure bonding unit 21 to perform thermocompression bonding of the component 3 to the substrate 2.

[0072] The memory unit 320 is a storage device that stores various types of information. For example, the memory unit 320 stores threshold information such as a thermocompression bonding time used when thermocompression bonding the component 3 to the substrate 2. The memory unit 320 also stores, for example, crimping tool usage information that indicates whether each of the multiple crimping tools is an active tool or an inactive tool in each crimping operation. The control unit 310 controls the supply of the multiple protective sheets 43 by, for example, controlling the multiple release mechanisms 500 based on the crimping tool usage information. The memory unit 320 is realized, for example, by an HDD (Hard Disk Drive) or a semiconductor memory.

[0073] [Specific example] Next, a specific example of the operation of the multiple crimping tools 33 and the multiple release mechanisms 500 will be described.

[0074] Fig. 6 is a diagram for explaining a specific example of pressing a plurality of components 3A to 3H against a substrate 2 by a plurality of pressure bonding tools 33A to 33F according to the embodiment. Fig. 7 is a diagram for explaining a specific example of the operation of a plurality of release mechanisms 500A to 500F according to the embodiment.

[0075] Each of the multiple crimping tools 33A to 33F is an example of the crimping tool 33. Each of the multiple components 3A to 3H is an example of the component 3. Each of the multiple release mechanisms 500A to 500F is an example of the release mechanism 500. The crimping tool 33A corresponds to the release mechanism 500A. Specifically, the release mechanism 500A controls the supply (feed operation) of the protective sheet 43 positioned below the crimping tool 33A. The crimping tool 33B corresponds to the release mechanism 500B. The crimping tool 33C corresponds to the release mechanism 500C. The crimping tool 33D corresponds to the release mechanism 500D. The crimping tool 33E corresponds to the release mechanism 500E. The crimping tool 33F corresponds to the release mechanism 500F.

[0076] 7 indicates a state in which the protective sheet 43 is supplied, and indicates that the crimping tools 33 corresponding to the release mechanisms 500A to 500F perform a crimping operation (pressing operation). That is, in the "release OFF" state shown in FIG. 7, the release mechanisms 500A to 500F are in a state similar to the release mechanism 500 shown in FIG. 5(a). In the "release OFF" state shown in FIG. 7, the crimping tools 33A to 33F corresponding to the release mechanisms 500A to 500F become the tools in use.

[0077] 7 indicates a state in which the protective sheet 43 is not supplied, and indicates that the crimping tools 33 corresponding to the release mechanisms 500A to 500F do not perform a crimping operation (pressing operation). That is, in the "Release ON" state shown in FIG. 7, the release mechanisms 500A to 500F are in the same state as the release mechanism 500 shown in FIG. 5(b). In the "Release ON" state shown in FIG. 7, the crimping tools 33A to 33F corresponding to the release mechanisms 500A to 500F are inactive tools.

[0078] In the example shown in FIGS. 6 and 7, the components 3A to 3H arranged on the substrate 2 are pressure-bonded in three separate steps.

[0079] In the first crimping (S110), for example, components 3A to 3F arranged at the ends of the long sides of the rectangular substrate 2 in a plan view are crimped onto the substrate 2. In this case, for example, all of the release mechanisms 500A to 500F are released to the OFF position, and protective sheets 43 are supplied below all of the crimping tools 33A to 33F. In this case, all of the crimping tools 33A to 33F are used tools, and the crimping tool 33A presses component 3A onto the substrate 2 via protective sheet 43, the crimping tool 33B presses component 3B onto the substrate 2 via protective sheet 43, the crimping tool 33C presses component 3C onto the substrate 2 via protective sheet 43, the crimping tool 33D presses component 3D onto the substrate 2 via protective sheet 43, the crimping tool 33E presses component 3E onto the substrate 2 via protective sheet 43, and the crimping tool 33F presses component 3F onto the substrate 2 via protective sheet 43.

[0080] Next, in order to crimp-bond the components 3G and 3H arranged at the ends of the short sides of the substrate 2 to the substrate 2, the control unit 310, for example, controls the movement mechanism 12b to perform side switching, which rotates the substrate 2 (S120). The control unit 310 controls the movement mechanism 12b to move the substrate placement unit 12a, i.e., the substrate 2, so that at least one of the components 3G and 3H is positioned below one of the multiple crimping tools 33A to 33F. In this example, the substrate 2 is moved so that the component 3H is positioned below the crimping tool 33C.

[0081] In the second crimping (S130), component 3H is crimped onto board 2. In this case, for example, only release mechanism 500C is released OFF, and protective sheet 43 is supplied only below crimping tool 33C. On the other hand, in this case, for example, release mechanisms 500A, 500B, 500D to 500F are released ON, and protective sheet 43 is not supplied below crimping tools 33A, 33B, 33D to 33F. Also, in this case, crimping tool 33C is the active tool, and component 3H is pressed onto board 2 via protective sheet 43 by crimping tool 33C. Also, in this case, crimping tools 33A, 33B, 33D to 33F are idle tools, and do not perform crimping operations.

[0082] Next, in order to perform pressure bonding to the component 3G on the substrate 2, for example, the control unit 310 controls the movement mechanism 12b to move the substrate placement unit 12a, i.e., the substrate 2, so that the component 3H is located below one of the plurality of pressure bonding tools 33A to 33F. In this example, the substrate 2 is moved so that the component 3G is located below the pressure bonding tool 33D.

[0083] In the third crimping (S140), component 3G is crimped onto board 2. In this case, for example, only release mechanism 500D is released OFF, and protective sheet 43 is supplied only below crimping tool 33D. On the other hand, in this case, for example, release mechanisms 500A to 500C, 500E, and 500F are released ON, and protective sheet 43 is not supplied below crimping tools 33A to 33C, 33E, and 33F. Also, in this case, crimping tool 33D is the active tool, and component 3G is pressed onto board 2 via protective sheet 43 by crimping tool 33D. Also, in this case, crimping tools 33A to 33C, 33E, and 33F are idle tools, and do not perform crimping operations.

[0084] [Processing Procedure] Next, a description will be given of a processing procedure of the component crimping apparatus 100 according to the embodiment. The component crimping apparatus 100 executes, for example, the component crimping method described below.

[0085] FIG. 8 is a flowchart showing a component crimping method according to an embodiment.

[0086] First, the control unit 310 places the substrate 2 on the substrate placement unit 12a, on which a plurality of components 3 are mounted (S10). Specifically, the control unit 310 controls a substrate transport device (not shown) to receive the substrate 2 from an upstream device (e.g., a temporary pressure bonding device) and place the received substrate 2 on the substrate placement unit 12a. Note that step S10 may be executed by equipment and a control device of a mounting system including the component pressure bonding apparatus 100. The substrate transport device may be included in the component pressure bonding apparatus 100 or the mounting system. Furthermore, for example, the control unit 310 controls the movement mechanism 12b to move the substrate placement unit 12a so that the components 3 are positioned below the pressure bonding tool 33.

[0087] Next, the control unit 310 uses the protective sheet supply unit 22 to supply the protective sheet 43 between the crimping tool 33 and the component 3 (S20). Specifically, the control unit 310 controls the multiple release mechanisms 500 to control whether or not to supply each of the multiple protective sheets 43. More specifically, based on the crimping tool usage information, the control unit 310 moves the protective sheet 43 located below a used tool among the multiple crimping tools 33 so that a position on the protective sheet 43 that is not pressed by the used tool is located below the used tool. Furthermore, based on the crimping tool usage information, if the multiple crimping tools 33 include one or more inactive tools, the control unit 310 controls the release mechanism 500 corresponding to the inactive tool so as not to move the protective sheet 43 located below the one or more inactive tools.

[0088] Next, the control unit 310 performs a pressing operation using the multiple crimping tools 33 to press each of the multiple components 3 against the substrate 2 via the protective sheet 43 (S30). Specifically, the control unit 310 controls the crimping unit 21 to cause the crimping unit 21 (specifically, the crimping tools 33) to thermocompression bond the components 3 to the substrate 2.

[0089] 6, the thermocompression bonding of the components 3 to the substrate 2 may be performed in multiple steps. In this case, in each thermocompression bonding, one component 3 may be thermocompression bonded to the substrate 2, or multiple components 3 may be thermocompression bonded to the substrate 2.

[0090] The substrate 2 to which the components 3 have been thermocompression bonded is transported, for example, by a substrate transport device to a downstream device (for example, an unloader).

[0091] [Effects, etc.] Below, examples of techniques that can be obtained from the disclosure of this specification will be given, and the effects and the like that can be obtained from the exemplified techniques will be described.

[0092] Technology 1 relates to a component crimping device 100 including a substrate mounting section 12a on which a substrate 2 having a plurality of components 3 mounted thereon is mounted, a plurality of crimping tools 33 that perform a pressing operation to press each of the plurality of components 3 against the substrate 2 via a protective sheet 43, a protective sheet supply section 22 that supplies the protective sheet 43 between the crimping tool 33 and the components 3, and a control section 310 that controls the protective sheet supply section 22 and the plurality of crimping tools 33, wherein the protective sheet supply section 22 includes a feed roller 45 that collectively performs a feeding operation of the plurality of protective sheets 43 drawn out from each of the plurality of supply reels 42, a plurality of pressure rollers 410 that press each of the plurality of protective sheets 43 against the feed roller 45, and a plurality of release mechanisms 500 that release the pressure of the plurality of pressure rollers 410 against the feed roller 45, and the control section 310 controls the plurality of release mechanisms 500 to control whether or not each of the plurality of protective sheets 43 is supplied.

[0093] When the component crimping device is equipped with multiple crimping tools, a protective sheet supply unit included in a conventional component crimping device supplies protective sheets to positions corresponding to the multiple crimping tools (specifically, below the multiple crimping tools). In this case, the conventional protective sheet supply unit uses a single feed roller to supply multiple protective sheets collectively to the positions corresponding to the multiple crimping tools. As a result, when there is a crimping tool (a resting tool) among the multiple crimping tools that is not performing a crimping operation, the protective sheet is supplied not only below the crimping tool performing the crimping operation but also below the resting tool. In this way, conventional protective sheet supply units may supply protective sheets unnecessarily, potentially resulting in wasteful consumption of protective sheets.

[0094] Therefore, the protective sheet supply unit 22 provided in the component crimping apparatus 100 according to the embodiment includes a plurality of release mechanisms 500 corresponding to the plurality of crimping tools 33. The release mechanisms 500 switch between pressing the pressure roller 410 against the feed roller 45. In other words, the release mechanisms 500 control the supply of the protective sheet 43 by switching between pressing the pressure roller 410 against the feed roller 45. This prevents the protective sheet 43 from being unnecessarily supplied, thereby reducing wasteful consumption of the protective sheet 43.

[0095] Technology 2 is the component crimping device 100 described in Technology 1, in which, when the crimping tool presses the component 3 toward the substrate 2, if there is a resting tool among the multiple crimping tools 33 that is not performing a pressing operation, the control unit 310 causes one of the multiple release mechanisms 500 corresponding to the resting tool to release the pressure roller 410 corresponding to the resting tool from pressing against the feed roller 45, thereby stopping the supply of the protective sheet 43 to the position corresponding to the resting tool.

[0096] This allows a plurality of protective sheets to be fed collectively using one feed roller 45, as is the case with conventional component crimping devices, while preventing unnecessary feeding of protective sheet 43.

[0097] Technique 3 is a component crimping method performed by component crimping device 100, in which a substrate 2 having a plurality of components 3 mounted thereon is placed on substrate mounting section 12a (S10), a protective sheet 43 is supplied between crimping tool 33 and components 3 using protective sheet supply section 22 (S20), and a pressing operation is performed using multiple crimping tools 33 to press each of the multiple components 3 against substrate 2 via the protective sheet 43 (S30), in which protective sheet supply section 22 is equipped with feed roller 45 that collectively performs the feeding operation of multiple protective sheets 43 drawn out from multiple supply reels 42, multiple pressure rollers 410 that press each of the multiple protective sheets 43 against feed roller 45, and multiple release mechanisms 500 that release the pressure of each of the multiple pressure rollers 410 against feed roller 45, and in the supply of protective sheet 43 (S20), the multiple release mechanisms are controlled to control whether each of the multiple protective sheets is supplied.

[0098] This provides the same effects as the component crimping device 100 described in the first technique.

[0099] These comprehensive or specific aspects may be realized as a system, a method, an integrated circuit, a computer program, or a non-transitory recording medium such as a computer-readable CD-ROM, or may be realized as any combination of a system, a method, an integrated circuit, a computer program, and a recording medium.

[0101] For example, the component crimping apparatus 100 may include a plurality of crimping tools 33, and may be less than six or seven or more. The component crimping apparatus 100 may include a plurality of release mechanisms 500, and may be less than six or seven or more. The component crimping apparatus 100 may include a plurality of pressure rollers 410, and may be less than six or seven or more. For example, the component crimping apparatus 100 may include a plurality of protective sheet supply systems, each including a crimping tool 33, a pressure roller 410 that presses a protective sheet 43 supplied below the crimping tool 33 against a feed roller 45, and a release mechanism 500 that releases the pressure roller 410 from pressing the protective sheet 43 against the feed roller 45.

[0102] Furthermore, for example, the control device 300 may be a computer dedicated to controlling each device provided in the component crimping device 100, or may be a computer that also controls each device provided in a mounting system that includes the component crimping device 100.

[0103] Also, for example, in the above embodiment, all or some of the components of the control device 300 may be configured with dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or processor reading and executing a software program recorded on a recording medium such as a HDD or semiconductor memory.

[0104] Furthermore, the components of the control device 300 may be configured with one or more electronic circuits. Each of the one or more electronic circuits may be a general-purpose circuit or a dedicated circuit.

[0105] The one or more electronic circuits may include, for example, a semiconductor device, an IC, or an LSI (Large Scale Integration). The IC or LSI may be integrated on a single chip or on multiple chips. Although we refer to them as ICs or LSIs here, they may be called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration) depending on the degree of integration. Also, a field programmable gate array (FPGA), which is programmed after the LSI is manufactured, can be used for the same purpose.
