[0070] (Implementation Method)

[0071] [structure]

[0072] First, the structure of the component crimping device involved in the embodiment will be described.

[0073] Figure 1 This is a block diagram illustrating the component crimping device 100 according to the embodiment. Figure 2 This is a perspective view showing the specific structure of the heat-pressing mechanism 200 according to the embodiment. Figure 3 This is a side view showing the specific structure of the heat-pressing mechanism 200 according to the embodiment.

[0074] The component pressing apparatus 100 is an apparatus for pressing (more specifically, heat-pressing) a component 3 onto a substrate 2. The component pressing apparatus 100 is, for example, part of a component mounting system used in the production of display panels, etc. In this component mounting system, for example, an anisotropic conductive film such as ACF is adhered to an electrode portion provided on the substrate 2, the component 3 is disposed (pre-pressed) onto the substrate 2 via the anisotropic conductive film, and the pre-pressed substrate 2 and component 3 are heat-pressed together. This mounting system includes, for example: an adhesion device for adhering anisotropic conductive film to the substrate 2; a pre-pressing device for disposing (pre-pressing) the component 3 onto the substrate 2 via the anisotropic conductive film; and a final pressing device for heat-pressing (finally pressing) the component 3 onto the substrate 2. For example, the component pressing apparatus 100 is a final pressing device included in this mounting system.

[0075] The component crimping device 100 performs formal crimping on substrate 2 and component 3, which are transported from an upstream device (e.g., a pre-crimping device) to substrate placement section 12a by a substrate transport device (not shown). The substrate 2, whose component 3 has been formally crimped, is transported to a downstream device (e.g., an unloading machine) by the substrate transport device.

[0076] As substrate 2, an example is a flexible substrate including resin, etc. Alternatively, substrate 2 may also be a display panel using a glass substrate, etc.

[0077] As part 3, examples include flexible components such as TCP (Tape Carrier Package) and FPC (Flexible Printed Circuits) or IC (Integrated Circuit) chips.

[0078] The component crimping device 100 includes a heat crimping mechanism 200 and a control device 300.

[0079] The heat-pressing mechanism 200 is a mechanism for heat-pressing the substrate 2 and the component 3. For example, the heat-pressing mechanism 200 is controlled by the control device 300 (specifically, the control unit 310) to heat-press the component 3 onto the substrate 2. In this embodiment, the heat-pressing mechanism 200 includes: a base 11, a substrate positioning part 12, a portal frame 13, a support platform 14, a touch panel 16, a pressing part 21, a protective sheet supply part 22, a unit support part 23, and a camera 50 for alignment. In addition, the substrate positioning part 12 includes a substrate placement part 12a and a moving mechanism 12b. The pressing part 21 includes: a lifting motor 31, a lifting base 32, a pressing tool 33, a pressure cylinder 34, and a heater 35.

[0080] The heat-pressing mechanism 200 has a substrate positioning section 12 on the negative Y-axis side of the base 11, and a portal frame 13 and a support platform 14 on the positive Y-axis side of the substrate positioning section 12. Additionally, an alignment camera 50 for positioning the substrate 2 at a given position is disposed on the base 11. A touch panel 16, serving as an input / output device for operator use, is disposed on the negative Y-axis side of the base 11.

[0081] The substrate positioning unit 12 is a mechanism for positioning a substrate 2, on which the component 3 is pre-mounted, at a given position. The substrate positioning unit 12 includes: a substrate mounting unit 12a for holding the substrate 2 in a horizontal position; and a moving mechanism 12b for moving the substrate mounting unit 12a in three dimensions while maintaining the horizontal position.

[0082] The substrate mounting section 12a is a stage (worktable) for mounting (arranging) a substrate 2 on which multiple components 3 are mounted. Specifically, the substrate 2 on which the components 3 are arranged via anisotropic conductive films is mounted is mounted in the substrate mounting section 12a. In the substrate mounting section 12a, for example, the substrate 2 transported by the aforementioned substrate transport device is mounted with the end on which the components 3 are mounted exposed. Thus, the substrate mounting section 12a has a holding surface for mounting the substrate 2 with the end that is the outer edge of the substrate 2 exposed from the substrate mounting section 12a (more specifically, with the lower end not overlapping the substrate mounting section 12a when viewed from above). When the components 3 are pressed onto the substrate 2, the end of the substrate 2 is supported by the support stage 14.

[0083] Furthermore, an adsorption mechanism for adsorbing the substrate 2 onto the holding surface may also be provided in the substrate mounting portion 12a. For example, an opening (e.g., a through hole) is formed in the holding surface, and the substrate mounting portion 12a adsorbs and holds the substrate 2 onto the holding surface. This opening may, for example, be connected to an adsorption device that attracts the substrate 2 to the holding surface by drawing air through the opening, thereby adsorbing and holding the substrate 2 onto the holding surface by drawing air through the adsorption device. The adsorption mechanism may, for example, include a vacuum pump for drawing air, a vacuum pipe connecting the vacuum pump and the opening, and a valve for controlling the suction.

[0084] The control unit 310, described later, controls the valve to switch whether the holding surface generates an adsorption force through the adsorption mechanism, that is, whether the adsorption mechanism adsorbs the end of the substrate 2.

[0085] In addition, the valves in the adsorption mechanism can be, for example, solenoid valves for switching the opening and closing of air attraction, or pressure regulating valves (so-called pressure regulators) for switching attraction force (adsorption force).

[0086] Alternatively, the substrate mounting portion 12a may not have the aforementioned opening on the holding surface, and the substrate 2 may be placed only on the holding surface 111, thereby holding the substrate 2 on the holding surface.

[0087] The substrate mounting section 12a is configured to be movable by the moving mechanism 12b, for example.

[0088] The moving mechanism 12b is a mechanism for moving the substrate mounting section 12a. For example, a three-axis stage is constructed by the substrate mounting section 12a and the moving mechanism 12b. The moving mechanism 12b is implemented, for example, by a conveyor configured to allow the substrate mounting section 12a to move arbitrarily along the XY plane and to be able to move up and down along the Z-axis direction.

[0089] The moving mechanism 12b moves the end of the substrate 2 toward the support platform 14 (more specifically, directly above) by moving the substrate mounting portion 12a on which the substrate 2 is mounted.

[0090] The portal frame 13 has a crossbeam 13a extending along the X-axis direction above the center of the base 11. A pressing part 21 is provided on the lower surface of the crossbeam 13a. A support platform 14 is provided below the pressing part 21 and extending along the X-axis direction. A supply device 600 of the protective sheet supply unit 22 is provided between the pressing part 21 and the support platform 14. The supply device 600 is a structure that is detachably mounted on the unit support part 23 provided on the base 11.

[0091] The crimping section 21 includes a lifting base 32 that rises and falls with the operation of a lifting motor 31. Multiple crimping tools 33 are provided on the lifting base 32. In this embodiment, the crimping section 21 includes six crimping tools 33.

[0092] Multiple crimping tools 33 perform a pressing action, pressing multiple components 3 toward the substrate 2 through the protective sheet 43; this is called crimping (pressing action) of the components 3 toward the substrate 2. Each crimping tool 33 is arranged along the X-axis. Each crimping tool 33 is located directly above the support platform 14 and is individually raised and lowered by a pressure cylinder 34 corresponding to each crimping tool 33. Each crimping tool 33 has a built-in heater 35.

[0093] Heater 35 is used to heat the crimping tool 33. Heater 35 heats the crimping tool 33, which presses the component 3 against the substrate 2, thereby thermally bonding the component 3 to the substrate 2. Heater 35 can be implemented, for example, by means of an electric heating wire or a Peltier element.

[0094] 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.

[0095] Figure 4 This is a perspective view showing the specific structure of the supply device 600 according to the embodiment.

[0096] The supply device 600 includes: a housing 41, multiple supply spools 42, guide rollers 44, feed rollers 45, drive motor 47, multiple pressing mechanisms 400, and block support 610.

[0097] The supply device 600 includes a plurality of supply reels 42 (in this embodiment, there are six, corresponding to the number of crimping tools 33) within a housing 41 forming the outer contour. Each supply reel 42 holds a protective sheet 43 in a wound state. Inside the housing 41, the rotation shafts are arranged along the X-axis direction with the shafts facing the X-axis. A plurality of guide rollers 44 are provided at the center of the housing 41 in the Y-axis direction. In addition, a feed roller 45 and a plurality of pressing mechanisms 400 (in this embodiment, there are six, corresponding to the number of supply reels 42) are provided on the positive Y-axis side inside the housing 41.

[0098] Multiple guide rollers 44 guide the protective sheet 43 drawn from each supply reel 42 in the positive Y-axis direction, so that the central portion within the housing 41 is in a generally horizontal position. The portion of this central portion, located directly below the crimping tool 33, becomes the portion through which the crimping tool 33 presses the component 3 across the protective sheet 43 when the component 3 is pressed by the crimping tool 33 (described later).

[0099] The feed roller 45 simultaneously feeds multiple protective sheets 43 drawn from multiple supply spools 42. The feed roller 45 contacts each of the multiple protective sheets 43, and the feeding action of the multiple protective sheets 43 is performed by rotating them using a drive motor 47. Furthermore, in this embodiment, the action of the feed roller 45 contacting and rotating the multiple protective sheets 43 is referred to as the feeding action. Due to the release mechanism 500 described later, even when the feed roller 45 performs the feeding action, the protective sheets 43 may not move. Specific examples will be described later.

[0100] The feed roller 45 is positioned with its rotation axis facing the X-axis direction and contacts the portion of the protective sheet 43 that is further from the positive Y-axis direction than the guide roller 44 located on the side closest to the positive Y-axis direction.

[0101] The multiple pressing mechanisms 400 each have a pressing roller 410, a force spring 420, a force spring support 430, a pressing roller block 440, and a connecting part 450.

[0102] The push roller 410 is a clamping roller that, together with the feed roller 45, holds the protective sheet 43. Multiple push rollers 410 (six push rollers 410 in this embodiment) push multiple protective sheets 43 (six protective sheets 43 in this embodiment) toward the feed roller 45. The six push rollers 410 are arranged on the positive Y-axis side of the feed roller 45, and their rotation axes are arranged along the X-axis direction. Furthermore, each push roller 410 applies force on the positive Y-axis side via a force-applying spring 420, thereby pressing the protective sheet 43 against the feed roller 45 and ensuring close contact.

[0103] The force spring 420 is an elastic body used to push the push roller 410 against the feed roller 45 through the protective sheet 43. One end of the force spring 420 is mounted to a component that can rotatably support the push roller 410, and the other end is mounted to the push roller block 440.

[0104] The force spring support 430 is a support body that supports the force spring 420. The force spring support 430 is fixed to the block support 610 assembled in the housing 41. As a result, the force spring 420 pushes the push roller 410 against the feed roller 45.

[0105] The push roller block 440 is a component connected to the push roller 410 via the connecting part 450.

[0106] The connecting part 450 is a component with one end mounted to a member that rotatably supports the push roller 410 and the other end movably mounted to the push roller block 440. In this embodiment, the connecting part 450 is movable in the Y-axis direction.

[0107] The push roller 410, the push roller block 440, and the connecting part 450 are movably mounted on the force spring support part 430 in the Y-axis direction.

[0108] Outside the housing 41, a drive motor 47 is provided as a roller drive unit that rotates the feed roller 45. When the feed roller 45 is rotated around the X-axis by the drive motor 47 ( Figure 3As shown by arrow A), the protective sheet 43 is stretched in the positive Y-axis direction by the feed roller 45, drawn out from the supply reel 42, and fed in the positive Y-axis direction. The protective sheet 43 that has passed through the feed roller 45 will not be wound by the feed roller 45, and is guided to the area below the feed roller 45 and discharged to the area below the housing 41.

[0109] Here, when the push roller block 440 is moved in the positive Y-axis direction by the release device 700 (specifically, the release mechanism 500), the push roller 410, which is connected to the push roller block 440 via the connecting part 450, also moves in the positive Y-axis direction. As a result, the feed roller 45 and the push roller 410 do not contact each other. Therefore, the protective sheet 43 is not clamped by the feed roller 45 and the push roller 410, and even if the feed roller 45 rotates, it will not be fed in the positive Y-axis direction. In other words, the protective sheet 43 is not supplied.

[0110] The release device 700 is a device for controlling the supply of protective sheets 43. Specifically, the release device 700 is a device for switching whether to supply each of the plurality of protective sheets 43 (in this embodiment, six protective sheets 43) contained in the supply device 600. The release device 700 includes a plurality of release mechanisms 500 and an outer housing 710.

[0111] The release device 700 has multiple release mechanisms 500 (in this embodiment, there are 6, corresponding to the number of crimping tools 33) within the outer shell 710 that forms the outer contour.

[0112] The multiple release mechanisms 500 are mechanisms that release the pressure of the multiple push rollers 410 against the feed roller 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.

[0113] The release lever drive unit 510 is a device for driving (specifically, rotating) the release lever 530. The release lever drive unit 510 is configured, for example, by a cylinder for rotating the release lever 530.

[0114] The rotating part 520 is a support member that rotatably supports the release lever 530. The rotating part 520 is, for example, mounted on the outer casing 710 and supports the release lever 530.

[0115] The release lever 530 is a lever rotatably supported by the rotating part 520. The release lever 530 is, for example, a long strip of material, with its central portion supported by the rotating part 520, and one end rotated by the release lever drive part 510. Furthermore, when one end of the release lever 530 rotates by the release lever drive part 510, the other end causes the push roller block 440 to move. As a result, the feed roller 45 and the push roller 410 do not contact each other, and the protective sheet 43 is not supplied. Additionally, the other end of the release lever 530 is fitted to a lever spring 540.

[0116] The rod spring 540 is an elastic body that rotates the release lever 530. For example, one end of the rod spring 540 is fitted to the release lever 530, and the other end is fitted to the outer casing 710. The rod spring 540 is fitted to both the release lever 530 and the outer casing 710, such that the other end of the release lever 530 is stretched towards the outer casing 710. In this embodiment, when viewed in the YZ plane, the rod spring 540 stretches the other end of the release lever 530 clockwise about the rotating part 520. Therefore, for example, when the piston in the release lever drive part 510, which pushes one end of the release lever 530, moves towards the positive Y-axis direction, the rod spring 540 rotates the other end of the release lever 530 clockwise about the rotating part 520.

[0117] Figure 5 This is a diagram illustrating a specific example of the operation of the release mechanism 500 according to the embodiment. Specifically, Figure 5 (a) shows the state in which the push roller 410 pushes the protective sheet 43 against the feed roller 45. Figure 5 (b) shows the state in which the push roller 410 does not push the protective sheet 43 onto the feed roller 45.

[0118] exist Figure 5 In state (a) (also known as OFF), since the push roller 410 pushes the protective sheet 43 against the feed roller 45, the push roller 410 also rotates when the feed roller 45 is rotated by the drive motor 47, and the protective sheet 43 held by the feed roller 45 and the push roller 410 moves.

[0119] On the other hand, Figure 5 In state (b) (also known as ON), since the push roller 410 does not push the protective sheet 43 onto the feed roller 45, even if the feed roller 45 is rotated by the drive motor 47, the push roller 410 will not rotate, the feed roller 45 will be in an idle state, and the protective sheet 43, which is not held by the feed roller 45 and the push roller 410, will not move.

[0120] To switch the release mechanism 500 from disengaged to engaged, for example, the control unit 310 controls the release lever drive unit 510, which in turn rotates one end of the release lever 530 by pushing it in the negative Y-axis direction via a piston in the release lever drive unit 510. This causes the pressure roller block 440 to move in the positive Y-axis direction, and the pressure roller 410 also moves in the positive Y-axis direction. Thus, the release mechanism 500 is engaged, and even if the feed roller 45 rotates, the protective sheet 43 will not be supplied.

[0121] Furthermore, to switch the release mechanism 500 from being activated to being deactivated, for example, the control unit 310 controls the release lever drive unit 510 to move the piston in the positive Y-axis direction. This rotates the release lever 530 via the lever spring 540, causing the other end of the release lever 530 to move in the negative Y-axis direction. Additionally, the pressure roller 410 also moves in the negative Y-axis direction via the force spring 420. Thus, the release mechanism 500 is deactivated, and the protective sheet 43 is supplied when the feed roller 45 rotates.

[0122] In the pressing operation of component 3 performed by the hot pressing mechanism 200, firstly, the drive motor 47 controlled by the control unit 310 rotates the feed roller 45, making the pressing portion of the protective sheet 43 drawn from each supply reel 42 based on the pressing tool 33 an unused portion. Here, the control unit 310 first controls, for example, the release mechanism 500, which moves the push roller 410 that pushes the protective sheet 43 corresponding to the pressing tool 33 (also called the resting tool) among the plurality of pressing tools 33 that are not used for pressing component 3 to the substrate 2, thereby setting the release mechanism 500 to the disengaged state. After this, the control unit 310, for example, rotates the feed roller 45 by controlling the drive motor 47. Therefore, the unused portion of the protective sheet 43 is supplied to the position corresponding to the crimping tool 33 (also called the application tool) among the plurality of crimping tools 33 used for crimping the component 3 to the substrate 2, and the unused portion of the protective sheet 43 is not supplied to the position corresponding to the rest tool.

[0123] Next, the lifting motor 31, controlled by the control unit 310, operates to raise and lower the lifting base 32, positioning each crimping tool 33 in its initial position above the protective sheet 43. If each crimping tool 33 is in its initial position, the control unit 310 moves the substrate mounting portion 12a holding the substrate 2 via the moving mechanism 12b to position the substrate 2 below the crimping tool 33 corresponding to the component 3 pre-mounted on the substrate 2 via the anisotropic conductive film (in other words, above the support platform 14).

[0124] When the substrate 2 is positioned, the control unit 310 controls the pressure cylinder 34 to press the pressure cylinder 34 from its initial position onto one of the multiple crimping tools 33. The tool then descends from above the protective sheet 43 and, together with the protective sheet 43, presses the component 3 onto the substrate 2. During this pressing, the component 3, along with the substrate 2, is pushed against the support stage 14, and the anisotropic conductive film is heated by the component 3 via a heater 35 built into the crimping tool 33. Thus, the component 3 is thermally crimped (formally crimped) onto the substrate 2. During the pressing of the component 3 onto the substrate 2 by the crimping tool 33, the protective sheet 43 is positioned between the crimping tool 33 and the component 3; therefore, the crimping tool 33 does not contact the anisotropic conductive film, and a portion of the anisotropic conductive film does not adhere to the crimping tool 33.

[0125] When the component 3 is pressed onto 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) and return it to its initial position. Furthermore, if the crimping tool 33 is in its initial position, the control unit 310 controls the drive motor 47 to rotate the feed roller 45, and performs a renewal operation on the protective sheet 43 by drawing a given amount (length) of protective sheet 43 from the supply reel 42. During the renewal operation, the control unit 310 controls the protective sheet supply unit 22 to rotate the feed roller 45 by a preset rotation angle, so that only the portion of the multiple protective sheets 43 corresponding to the tool used in the next crimping operation is fed in the positive Y-axis direction, and the unused portion of the protective sheet 43 becomes the new pressing portion. Once the renewal operation of the protective sheet 43 is complete, the positioning of the substrate 2 and the pressing of the component 3 by the crimping tool 33 are repeatedly performed as described above.

[0126] The control device 300 is a computer that controls the moving mechanism 12b, the pressing part 21, and the protective sheet supply part 22 of the hot pressing mechanism 200.

[0127] The control device 300 is implemented through a communication interface for communicating with mechanisms such as the moving mechanism 12b, the pressing part 21, and the protective sheet supply part 22 of the heat pressing mechanism 200; a non-volatile memory for storing programs; a volatile memory serving as a temporary storage area for executing programs; input / output ports for transmitting and receiving signals; and a processor for executing programs. This communication interface can be implemented, for example, using an antenna and wireless communication circuit to enable wireless communication, or using a connector connected to a communication line to enable wired communication.

[0128] The control device 300 includes a control unit 310 and a storage unit 320.

[0129] 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 provided in the hot pressing mechanism 200. For example, the control unit 310 controls the movement of the protective sheet 43 by controlling the drive motor 47 and the release lever drive unit 510 provided in the protective sheet supply unit 22. In addition, for example, the control unit 310 controls the lifting and lowering of the multiple crimping tools 33 individually by controlling the lifting motor 31 and the pressure cylinder 34. The control unit 310 includes, for example, a processor such as a CPU (Central Processing Unit) and a memory storing the control program executed by the processor.

[0130] For example, the control unit 310 controls the aforementioned substrate transport device to place the substrate 2, which carries multiple components 3, on the substrate mounting section 12a. Next, the control unit 310 controls the moving mechanism 12b to move the substrate mounting section 12a. For example, the control unit 310 controls the moving mechanism 12b based on the imaging results of the alignment camera 50, so that the end of the substrate 2 is placed on the support stage 14. Further, the control unit 310 controls the protective sheet supply section 22 to supply the protective sheet 43 between the component 3 and the crimping tool 33. Specifically, the control unit 310 controls the protective sheet supply section 22 to supply the unused area of ​​the protective sheet 43 between the component 3 and the crimping tool 33. The so-called unused area refers to the area (part) of the protective sheet 43 that has not yet been pressed by the crimping tool 33.

[0131] Here, the control unit 310 controls the supply of each of the multiple protective sheets 43 by controlling multiple release mechanisms 500. Specifically, the control unit 310 controls whether each of the multiple protective sheets 43 is supplied by controlling the multiple release mechanisms 500. For example, when the crimping tool presses the member 3 toward the substrate 2, if there is a resting tool among the multiple crimping tools 33 that has not performed a pressing action, the control unit 310 causes the release mechanism 500 corresponding to the resting tool among the multiple release mechanisms 500 to release the push roller 410 corresponding to the resting tool from the feed roller 45, thereby stopping the supply of the protective sheet 43 to the position corresponding to the resting tool. For example, because the number of crimping tools 33 provided in the component crimping device 100 is greater than the number of members 3 that are pressed onto the substrate 2 together, there may sometimes be more than one resting tool among the multiple crimping tools 33. Furthermore, the control unit 310 causes the crimping unit 21 to perform thermal crimping of the component 3 onto the substrate 2 by pressing the component 3 with the crimping tool 33 through the protective sheet 43.

[0132] The storage unit 320 is a storage device for storing various types of information. For example, the storage unit 320 stores threshold information such as the hot-pressing time used when hot-pressing the component 3 onto the substrate 2. Additionally, the storage unit 320 stores, for example, crimping tool utilization information indicating whether the multiple crimping tools are used or stopped during each crimping operation. The control unit 310 controls the multiple release mechanisms 500 based on the crimping tool utilization information, thereby controlling the supply of multiple protective sheets 43. The storage unit 320 is implemented, for example, using an HDD (Hard Disk Drive) or a semiconductor memory.

[0133] [Specific example]

[0134] Next, specific examples of the operation of the multiple crimping tools 33 and the multiple release mechanisms 500 will be explained.

[0135] Figure 6 This is a diagram illustrating a specific example of pressing multiple components 3A to 3H onto the substrate 2 using multiple pressing tools 33A to 33F involved in the embodiment. Figure 7 This is a diagram illustrating specific examples of the operation of the multiple release mechanisms 500A to 500F involved in the implementation method.

[0136] Furthermore, multiple crimping tools 33A to 33F are examples of crimping tool 33. Additionally, multiple components 3A to 3H are examples of component 3. Furthermore, multiple release mechanisms 500A to 500F are examples of release mechanisms 500. Crimping tool 33A corresponds to release mechanism 500A. Specifically, release mechanism 500A controls the supply (feed operation) of the protective sheet 43 located below crimping tool 33A. Crimping tool 33B corresponds to release mechanism 500B. Crimping tool 33C corresponds to release mechanism 500C. Crimping tool 33D corresponds to release mechanism 500D. Crimping tool 33E corresponds to release mechanism 500E. Crimping tool 33F corresponds to release mechanism 500F.

[0137] in addition, Figure 7 The "release disconnection" indicated by the symbol signifies the state of the protective sheet 43 being supplied, and indicates that the crimping tool 33 corresponding to the release mechanism 500A-500F has performed a crimping action (pressing action). In other words, in... Figure 7 In the "release disconnection" shown, the release mechanism 500A-500F becomes as follows: Figure 5 The release mechanism 500 is in the state shown in (a). Additionally, in Figure 7 In the “Release Disconnection” shown, the crimping tools 33A to 33F corresponding to the release mechanisms 500A to 500F become the utilization tools.

[0138] in addition, Figure 7 The "disconnect" indicated means that the protective sheet 43 is not supplied, and that the crimping tool 33 corresponding to the disconnection mechanism 500A-500F does not perform a crimping action (pressing action). In other words, in Figure 7 In the "deactivate" function shown, the deactivation mechanisms 500A to 500F become as follows: Figure 5 The release mechanism 500 is in the state shown in (b). Additionally, in Figure 7 In the “unconnection” shown, the crimping tools 33A to 33F corresponding to the release mechanisms 500A to 500F become the resting tools.

[0139] exist Figure 6 as well as Figure 7 In the example shown, the crimping of components 3A to 3H disposed on substrate 2 is performed in three steps.

[0140] In the first pressing (S110), for example, the components 3A to 3F, which are located at the ends of the long sides of the rectangular substrate 2 as viewed from above, are pressed onto the substrate 2. In this case, for example, all the release mechanisms 500A to 500F are released and disconnected, and the protective sheet 43 is supplied below all the pressing tools 33A to 33F. In this case, all of the crimping tools 33A to 33F are tools used to press component 3A onto substrate 2 through protective sheet 43, component 3B onto substrate 2 through protective sheet 43, component 3C onto substrate 2 through protective sheet 43, component 3D onto substrate 2 through protective sheet 43, component 3E onto substrate 2 through protective sheet 43, and component 3F onto substrate 2 through protective sheet 43.

[0141] Next, in order to press the components 3G and 3H, which are disposed at the ends of the short sides of the substrate 2, onto the substrate 2, for example, the control unit 310 controls the moving mechanism 12b to perform a side-switching operation that rotates the substrate 2 (S120). The control unit 310 controls the moving mechanism 12b to move the substrate mounting unit 12a, i.e., the substrate 2, so that at least one of the components 3G and 3H is located below any of the plurality of pressing tools 33A to 33F. In this example, the substrate 2 is moved so that the component 3H is located below the pressing tool 33C.

[0142] In the second pressing (S130), component 3H is pressed against substrate 2. In this case, for example, only the release mechanism 500C is released off, and only the protective sheet 43 is supplied to the underside of the pressing tool 33C. On the other hand, in this case, for example, the release mechanisms 500A, 500B, 500D to 500F are released on, and the protective sheet 43 is not supplied to the underside of the pressing tools 33A, 33B, 33D to 33F. In addition, in this case, the pressing tool 33C is an application tool, and component 3H is pressed against substrate 2 through the protective sheet 43. In addition, in this case, the pressing tools 33A, 33B, 33D to 33F are rest tools and do not perform pressing operations.

[0143] Next, in order to crimp the component 3G in the substrate 2, for example, the control unit 310 controls the moving mechanism 12b to move the substrate mounting unit 12a, i.e., the substrate 2, so that the component 3G is located below any of the multiple crimping tools 33A to 33F. In this example, the substrate 2 is moved so that the component 3G is located below the crimping tool 33D.

[0144] In the third pressing (S140), component 3G is pressed onto substrate 2. In this case, for example, only the release mechanism 500D is disengaged, and the protective sheet 43 is supplied only to the underside of the pressing tool 33D. On the other hand, in this case, for example, the release mechanisms 500A-500C, 500E, and 500F are deactivated, and the protective sheet 43 is not supplied to the underside of the pressing tools 33A-33C, 33E, and 33F. In addition, in this case, the pressing tool 33D is an application tool, and component 3G is pressed onto substrate 2 through the protective sheet 43. In addition, in this case, the pressing tools 33A-33C, 33E, and 33F are rest tools and do not perform pressing operations.

[0145] [Processing Procedure]

[0146] Next, the processing procedure of the component crimping apparatus 100 according to the embodiment will be described. The component crimping apparatus 100 performs, for example, the component crimping method shown below.

[0147] Figure 8 This is a flowchart illustrating the component crimping method according to the embodiment.

[0148] First, the control unit 310 places the substrate 2, on which multiple components 3 are mounted, on the substrate placement section 12a (S10). Specifically, the control unit 310 receives the substrate 2 from an upstream device (e.g., a pre-pressing device) by controlling a substrate transport device (not shown) and places the received substrate 2 on the substrate placement section 12a. Furthermore, step S10 can also be performed using a device equipped with a mounting system including a component pressing device 100 and a control device. The substrate transport device can be provided by the component pressing device 100 or by the mounting system. Additionally, for example, the control unit 310 controls the moving mechanism 12b to move the substrate placement section 12a, positioning the components 3 below the pressing tool 33.

[0149] 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 whether each of the multiple protective sheets 43 is supplied by controlling multiple release mechanisms 500. More specifically, based on the crimping tool utilization information, the control unit 310 moves the protective sheet 43 located below the utilization tool among the multiple crimping tools 33, so that the position of the protective sheet 43 not pressed by the utilization tool is located below the utilization tool. In addition, based on the crimping tool utilization information, if there is more than one rest tool among the multiple crimping tools 33, the control unit 310 controls the release mechanism 500 corresponding to the rest tool, so that the protective sheet 43 located below the more than one rest tool does not move.

[0150] Next, the control unit 310 uses multiple crimping tools 33 to perform a pressing action (S30) to press multiple components 3 toward the substrate 2 through the protective sheet 43. Specifically, the control unit 310 controls the crimping unit 21 to perform thermal crimping of the components 3 toward the substrate 2.

[0151] In addition, in step S130, it is also possible to do as follows: Figure 6 As shown in steps S110 to S140, the hot pressing of component 3 onto substrate 2 is performed multiple times. In this case, in each hot pressing, one component 3 may be hot pressed onto substrate 2, or multiple components 3 may be hot pressed onto substrate 2.

[0152] The substrate 2, which is heat-pressed by component 3, is transported to a downstream device (e.g., an unloading machine) via a substrate transport device.

[0153] [Effects, etc.]

[0154] Hereinafter, the technology obtained based on the disclosure of this specification will be illustrated, and the effects obtained based on the illustrated technology will be explained.

[0155] Technology 1 is a component pressing device 100, comprising: a substrate mounting section 12a for mounting a substrate 2 on which a plurality of components 3 are mounted; a plurality of pressing tools 33 for pressing the plurality of components 3 toward the substrate 2 with protective sheets 43 in between; a protective sheet supply section 22 for supplying protective sheets 43 between the pressing tools 33 and the components 3; and a control section 310 for controlling the protective sheet supply section 22 and the plurality of pressing tools 33. The protective sheet supply section 22 comprises: a feed roller 45 for feeding the plurality of protective sheets 43 drawn from the plurality of supply spools 42; a plurality of push rollers 410 for pushing the plurality of protective sheets 43 toward the feed rollers 45; and a plurality of release mechanisms 500 for releasing the push of the plurality of push rollers 410 toward the feed rollers 45. The control section 310 controls whether to supply each of the plurality of protective sheets 43 by controlling the plurality of release mechanisms 500.

[0156] In conventional component crimping devices, the protective sheet supply unit supplies protective sheets to positions corresponding to each crimping tool (specifically, below each crimping tool) when the device has multiple crimping tools. In this case, the conventional protective sheet supply unit uses a single feed roller to supply multiple protective sheets to the positions corresponding to the multiple crimping tools simultaneously. This means that if one of the crimping tools is not performing a crimping action (a resting tool), the protective sheet is supplied not only below the crimping tool that is performing the crimping action but also below the resting tool. Thus, in conventional protective sheet supply units, protective sheets are sometimes unnecessarily supplied, and the protective sheets may be wasted.

[0157] Therefore, the component crimping apparatus 100 according to the embodiment includes a protective sheet supply unit 22 and a plurality of crimping tools 33, each equipped with a plurality of release mechanisms 500. The release mechanism 500 switches whether the push roller 410 is pressed against the feed roller 45. In other words, the release mechanism 500 controls the supply of the protective sheet 43 by switching whether the push roller 410 is pressed against the feed roller 45. This suppresses unnecessary supply of the protective sheet 43, thus preventing the wasteful consumption of the protective sheet 43.

[0158] Technology 2 is that, in the component pressing apparatus 100 described in Technology 1, when the pressing tool presses the component 3 toward the substrate 2, if there is a resting tool among the plurality of pressing tools 33 that does not perform a pressing action, the control unit 310 causes the release mechanism 500 corresponding to the resting tool among the plurality of release mechanisms 500 to release the push roller 410 corresponding to the resting tool from the feed roller 45, thereby stopping the supply of the protective sheet 43 to the position corresponding to the resting tool.

[0159] Therefore, it is possible to utilize a single feed roller 45, which can simultaneously feed multiple protective sheets, in a conventional component pressing device, and to suppress unnecessary supply of protective sheets 43.

[0160] Technology 3 is a component pressing method performed by a component pressing device 100. In this component pressing method, a substrate 2 on which multiple components 3 are mounted is placed on a substrate mounting section 12a (S10). A protective sheet 43 is supplied between a pressing tool 33 and a component 3 using a protective sheet supply section 22 (S20). Multiple pressing tools 33 are used to press the multiple components 3 toward the substrate 2 with the protective sheet 43 in between (S30). The protective sheet supply section 22 includes: a feed roller 45 that feeds multiple protective sheets 43 drawn from multiple supply spools 42; multiple push rollers 410 that push the multiple protective sheets 43 toward the feed roller 45; and multiple release mechanisms 500 that release the push rollers 410 from the feed rollers 45. During the supply of the protective sheet 43 (S20), the supply of each of the multiple protective sheets is controlled by controlling the multiple release mechanisms.

[0161] Thus, it achieves the same effect as the component crimping device 100 described in Technique 1.

[0162] Furthermore, these general or specific methods can be implemented through systems, methods, integrated circuits, computer programs, or non-transitory recording media such as computer-readable CD-ROMs, or through any combination of systems, methods, integrated circuits, computer programs, and recording media.

[0163] (Other implementation methods)

[0164] The component crimping device and the like involved in this embodiment have been described above based on the above embodiments, but the present invention is not limited to the above embodiments.

[0165] For example, the number of crimping tools 33 provided in the component crimping device 100 can be multiple, or less than 6, or more than 7. Similarly, the number of releasing mechanisms 500 provided in the component crimping device 100 can be multiple, or less than 6, or more than 7. Furthermore, the number of push rollers 410 provided in the component crimping device 100 can be multiple, or less than 6, or more than 7. For example, the component crimping device 100 only needs to provide multiple protective sheet supply systems, each including a crimping tool 33, a push roller 410 that pushes the protective sheet 43 supplied below the crimping tool 33 towards a feed roller 45, and a releasing mechanism 500 for releasing the pressure exerted by the push roller 410 on the protective sheet 43 towards the feed roller 45.

[0166] Alternatively, for example, the control device 300 may be a dedicated computer for controlling each device included in the component crimping device 100, or it may be a computer that also controls each device included in the installation system that includes the component crimping device 100.

[0167] Furthermore, for example, in the above-described embodiments, all or part of the structural elements of the control device 300 may be constructed by dedicated hardware, or may be implemented by executing software programs suitable for each structural element. Each structural element may also be implemented by a program execution unit such as a CPU or processor reading and executing software programs recorded in a recording medium such as an HDD or semiconductor memory.

[0168] Furthermore, the structural elements of the control device 300 can also be composed of one or more electronic circuits. These one or more electronic circuits can be general-purpose circuits or dedicated circuits.

[0169] One or more electronic circuits may include semiconductor devices, ICs, or LSIs (Large Scale Integration). ICs or LSIs can be integrated onto a single chip or multiple chips. Here, they are referred to as ICs or LSIs, but the terminology may vary depending on the degree of integration; they may be called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration). Alternatively, FPGAs (Field Programmable Gate Arrays) can be used for the same purpose, programmable after the LSI is manufactured.

[0170] Furthermore, the present invention also includes various modifications that can be conceived by those skilled in the art in implementing each embodiment, and the ways in which structural elements and functions of each embodiment are arbitrarily combined without departing from the spirit of the present invention.
