Description

Technical Field

[0001] The present invention relates to a component pressing apparatus and a component pressing method for pressing components onto a substrate. Background Technology

[0002] In the past, there have been component pressing devices for pressing electronic components and other components onto substrates such as display panels. In the thermal pressing of components onto the substrate, a method is sometimes used to install a protective sheet between a pressing tool such as a pressing head and the component being pressed onto the substrate by the pressing head, which protects the component from the impact of the pressing pressure (when pressed). Patent Document 1 discloses a component pressing device equipped with a device for supplying the protective sheet.

[0003] Patent Document 1 discloses a component pressing device that presses (formally presses) a component pre-mounted (pre-presses) on the edge of a substrate onto the substrate. The component is mounted on the substrate through an adhesive composed of anisotropic conductive members called ACF (Anisotropic Conductive Film). To prevent the ACF from adhering to the pressing tool during the pressing operation, the pressing tool presses the component through a protective sheet disposed below it.

[0007] The protective sheet, for example, is provided in a roll form and is fed after use via a sheet feeding mechanism such as a reel. The protective sheet, used to protect components when pressed onto a substrate, is made of resin and may sometimes become wrinkled due to deformation. Therefore, such deformation can sometimes cause positional deviations in the protective sheet, or it may be fed in a direction tilted relative to the proper feeding direction (supply direction). Consequently, if the protective sheet is not positioned to completely cover the component being pressed, the pressing force will be inaccurate, the pressing will not be performed correctly, and the substrate on which the component is pressed will become of poor quality. Summary of the Invention

[0008] The present invention provides a component crimping device, etc., that can suppress the occurrence of defective products.

[0009] One aspect of the present invention relates to a component pressing apparatus comprising: a substrate support portion that supports a substrate; a pressing tool that performs a pressing operation, the pressing operation being performed by pressing a component mounted on the substrate supported by the substrate support portion against the substrate through a protective sheet, thereby pressing the component onto the substrate; a protective sheet supply portion that performs a sheet feeding operation, the sheet feeding operation supplying the protective sheet between the component mounted on the substrate supported by the substrate support portion and the pressing tool; a detection portion that performs a detection operation, the detection operation detecting the protective sheet supplied by the sheet feeding operation; a determination portion that determines, based on the detection result of the detection portion, whether the position of the protective sheet in the width direction of the protective sheet has deviated; and an output portion that outputs result information representing the determination result of the determination portion.

[0010] In one aspect of the component crimping method of the present invention, a crimping tool performs a crimping action, which presses the component mounted on the substrate supported by a substrate support portion onto the substrate through a protective sheet, thereby crimping the component onto the substrate. A protective sheet supply unit performs a sheet feeding action, which supplies the protective sheet between the component mounted on the substrate supported by the substrate support portion and the crimping tool. A detection unit performs a detection action, which detects the protective sheet supplied by the sheet feeding action. A determination unit determines, based on the detection result of the detection unit, whether the position of the protective sheet in the width direction of the protective sheet has deviated. An output unit outputs result information indicating the determination result of the determination unit.

[0060] (Implementation Method)

[0061] [structure]

[0062] First, the structure of the component crimping device involved in the implementation method will be explained.

[0063] Figure 1 This is a block diagram illustrating the component crimping device 100 involved in the embodiment. Figure 2 This is a side view showing the specific structure of the crimping mechanism 200 involved in the embodiment.

[0064] The component pressing apparatus 100 is an apparatus for pressing (more specifically, heat-pressing) component 3 onto 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 substrate 2, and component 3 is disposed (pre-pressed) onto substrate 2 through 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 the anisotropic conductive film to substrate 2; a pre-pressing device for disposing (pre-pressing) component 3 onto substrate 2 through the anisotropic conductive film; and a formal pressing device for heat-pressing (final pressing) component 3 onto substrate 2. For example, the component pressing apparatus 100 is the formal pressing device included in this mounting system.

[0065] The component pressing device 100 formally presses together a substrate 2 and a component 3 that are transported from an upstream device (e.g., a pre-pressing device) to a substrate placement section 12a by a substrate transport device (not shown). The substrate 2, to which the component 3 has been formally pressed, is transported, for example, by the substrate transport device to a downstream device (e.g., an unloading machine).

[0066] As substrate 2, a flexible substrate made of resin or the like is exemplified. Alternatively, substrate 2 can be a display panel utilizing a glass substrate or the like.

[0067] Component 3 is, for example, an electronic component such as a drive circuit. Examples of component 3 include flexible components such as TCP (Tape Carrier Package) and FPC (Flexible Printed Circuits) or IC (Integrated Circuit) chips.

[0068] The component crimping device 100 includes a crimping mechanism 200, a control device 300, and a notification device 400.

[0069] The pressing mechanism 200 is a mechanism for thermally pressing the substrate 2 and the component 3 together. For example, the pressing mechanism 200 is controlled by the control device 300 (specifically the control unit 310) to thermally press the component 3 onto the substrate 2. In this embodiment, the pressing mechanism 200 includes a base 11, a substrate support 14, a pressing part 21, a protective sheet supply part 22, and a detection part 50. 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.

[0070] Alternatively, a touch panel for input / output devices used by operators can be configured on the negative Y-axis side of the base 11.

[0071] 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 is mounted in the substrate mounting section 12a with an anisotropic conductive film in between. For example, the substrate 2 transported by the substrate transport device described above is mounted in the substrate mounting section 12a with the end of the component 3 extending beyond the substrate mounting section 12a. Thus, the substrate mounting section 12a has a holding surface for mounting the substrate 2 with the outer edge of the substrate 2, i.e., the end, extending beyond the substrate mounting section 12a (more specifically, the end does not overlap with the substrate mounting section 12a when viewed from above). When the component 3 is pressed onto the substrate 2, the end of the substrate 2 is supported by the substrate support section 14. The substrate support section 14 is a support stage for supporting the substrate 2. Specifically, the substrate support section 14 supports the end of the substrate 2 from below.

[0072] Alternatively, an adsorption mechanism for adsorbing the substrate 2 on the holding surface can 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 on the holding surface. An adsorption device is connected to this opening, for example, to adsorb the substrate 2 on the holding surface by drawing air through the opening. By drawing air through the adsorption device, the substrate 2 can be adsorbed and held on the holding surface. The adsorption mechanism includes, for example, a vacuum pump for drawing air, a vacuum pipe connecting the vacuum pump and the opening, and a valve for controlling the suction.

[0073] The control unit 310, described later, controls the valve to switch whether the adsorption mechanism generates an adsorption force on the holding surface, that is, to switch whether the adsorption mechanism adsorbs the end of the substrate 2.

[0074] 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).

[0075] Alternatively, the substrate mounting portion 12a may not have the opening described above on the holding surface, and the substrate 2 may be simply placed on the holding surface to hold the substrate 2.

[0076] The substrate mounting section 12a is configured to be movable by a moving mechanism (not shown). The moving mechanism is a mechanism for moving the substrate mounting section 12a. For example, the substrate mounting section 12a and the moving mechanism constitute a 3-axis stage. The moving mechanism is implemented, for example, by a conveyor configured to move the substrate mounting section 12a arbitrarily in the XY plane and to be able to move up and down in the Z-axis direction.

[0077] The crimping section 21 includes a lifting base 32 that is raised and lowered by 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.

[0078] The crimping tool 33 is a crimping head that performs a crimping operation. In this crimping operation, the component 3, which is mounted on the substrate 2 supported by the substrate support 14, is pressed against the substrate 2 through the protective sheet 43 to press the component 3 onto the substrate 2. Multiple crimping tools 33 perform a pressing operation that presses multiple components 3 onto the substrate 2 through the protective sheet 43, thus crimping the component 3 onto the substrate 2. The crimping tools 33 are arranged side-by-side in the X-axis direction. Each crimping tool 33 is located directly above the substrate support 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. The crimping tool 33 is heated by the heater 35 for use.

[0079] Heater 35 is used to heat crimping tool 33. By heating crimping tool 33 with heater 35, and then pressing part 3 onto substrate 2 with crimping tool 33, part 3 is thermally crimped to substrate 2. Heater 35 is implemented, for example, by heating wire or Peltier element.

[0080] The protective sheet supply unit 22 is a mechanism that supplies the protective sheet 43 between the crimping tool 33 and the component 3. Specifically, the protective sheet supply unit 22 performs a feeding operation (also referred to as sheet feeding operation) of the protective sheet 43 that supplies the protective sheet 43 between the component 3 of the substrate 2 supported by the substrate support unit 14 and the crimping tool 33.

[0081] Figure 3 This is a perspective view showing the specific structure of the protective sheet supply unit 22 involved in the embodiment.

[0082] The protective sheet supply unit 22 includes a housing 41, multiple supply reels 42, guide rollers 44, feed rollers 45, pressing rollers 46, and a drive motor 47.

[0083] The protective sheet supply unit 22 has multiple (in this embodiment, the number of supply reels 4 in conjunction with the crimping tool 33) supply reels 42 within the housing 41 that forms the outer contour.

[0084] The supply reel 42 holds the protective sheet 43. Each supply reel 42 holds the protective sheet 43 in a wound state inside the housing 41, arranged side by side in the X-axis direction with the rotation axis facing the X-axis. A plurality of guide rollers 44 are provided in the central part in the Y-axis direction inside the housing 41. In addition, one feed roller 45 and a plurality of (four in this embodiment, corresponding to the supply reel 42) pressing rollers 46 are provided on the positive Y-axis side inside the housing 41.

[0085] Multiple guide rollers 44 guide the protective sheet 43 extending from each supply reel 42 in the positive Y-axis direction, so that its central portion within the housing 41 is approximately horizontal. This central portion, located directly below the crimping tool 33, becomes the part of the crimping tool 33 that is pressed by the crimping tool 33 through the protective sheet 43 when the component 3 of the crimping tool 33 is pressed.

[0086] The feed roller 45 is a roller that simultaneously performs the sheet feeding operation for multiple protective sheets 43 drawn from multiple supply reels 42. Specifically, the feed roller 45 is located on the side opposite to the supply reel 42 in the supply direction of the protective sheets 43 supplied by the protective sheet supply section 22, and draws the protective sheets 43 from the supply reel 42, thereby performing the sheet feeding operation. The feed roller 45 rotates by the drive motor 47 by contacting the multiple protective sheets 43 respectively, thereby performing the sheet feeding operation for the multiple protective sheets 43. In this embodiment, the operation of the feed roller 45 contacting and rotating the multiple protective sheets 43 respectively is referred to as the sheet feeding operation.

[0087] The feed roller 45 is positioned with its rotation axis pointing in the X-axis direction and contacts the portion of the protective plate 43 that is further in the positive Y-axis direction than the guide roller 44 located on the side closest to the positive Y-axis direction.

[0088] The pressing roller 46 is a clamping roller that, together with the feed roller 45, clamps the protective sheet 43. Multiple pressing rollers 46 (four pressing rollers in this embodiment) press multiple protective sheets 43 (four protective sheets 43 in this embodiment) onto the feed roller 45. The four pressing rollers 46 are arranged side-by-side in the X-axis direction with their rotation axes pointing towards the X-axis. Furthermore, each pressing roller 46 presses the protective sheet 43 against the feed roller 45 and keeps it in close contact, for example, by applying force to the positive Y-axis direction using a force-applying spring mounted on the housing 41.

[0089] A drive motor 47, serving as a roller drive unit for rotating and driving the feed roller 45, is provided outside the housing 41. If the feed roller 45 is driven to rotate around the X-axis by the drive motor 47, the protective sheet 43 is pulled out from the supply reel 42 in the positive Y-axis direction by the feed roller 45 and fed towards the positive Y-axis. The protective sheet 43, having passed through the feed roller 45, is not wound up by the feed roller 45 but is guided below the feed roller 45 and discharged downwards from the housing 41.

[0090] During the crimping operation of component 3 of crimping mechanism 200, firstly, drive motor 47 controlled by control unit 310 causes feed roller 45 to rotate, and the pressing part of crimping tool 33 in protective sheet 43 drawn from each supply reel 42 becomes unused.

[0091] Next, the lifting motor 31, controlled by the control unit 310, operates to raise and lower the lifting base 32, so that each crimping tool 33 is 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 to position the substrate 2 so that the component 3, which is pre-mounted on the substrate 2 with an anisotropic conductive film in between, is located below the corresponding crimping tool 33 (in other words, above the substrate support portion 14).

[0092] If the substrate 2 is positioned, the control unit 310 controls the pressure cylinder 34 to press down multiple crimping tools 33 from their initial positions. As a result, the multiple crimping tools 33 descend from above the protective sheet 43, pressing the component 3 and the protective sheet 43 together onto the substrate 2. During this pressing, the component 3 presses each substrate 2 against the substrate support 14, and the anisotropic conductive film is heated by the heater 35 built into the crimping tool 33 via the component 3. Thus, the component 3 is thermally crimped (formally crimped) onto the substrate 2. When the component 3 of the crimping tool 33 presses against the substrate 2, since the protective sheet 43 is located between the crimping tool 33 and the component 3, 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.

[0093] If 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 to return to its initial position. Then, if the crimping tool 33 is in the 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 out 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 multiple protective sheets 43 are fed in the positive Y-axis direction, and the unused portion of the protective sheet 43 becomes the new pressing portion. If the renewal operation of 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 repeated as described above.

[0094] In this embodiment, the detection unit 50 performs a detection operation on the protective sheet 43 supplied between the component 3 and the crimping tool 33.

[0095] Figure 4 This is a perspective view showing the specific structure of the detection unit 50 involved in the embodiment.

[0096] The detection unit 50 is a device that performs a detection operation on the protective sheet 43 supplied by the sheet feeding operation performed by the protective sheet supply unit 22.

[0097] The detection unit 50 is implemented, for example, by an active sensor that emits light such as infrared light and detects reflected light from the protective sheet 43.

[0098] In this embodiment, the detection unit 50 includes a light sensor 51A, a light sensor 51B, and a fixture 52.

[0099] Optical sensors 51A and 51B are active sensors that emit light and detect reflected light from the protective sheet 43. For example, optical sensors 51A and 51B can be used to perform a detection operation on one protective sheet 43.

[0100] Light sensors 51A and 51B are configured, for example, to emit light from below the protective sheet 43 and detect reflected light from the protective sheet 43. For example, light sensors 51A and 51B are arranged side-by-side in the width direction (X-axis direction in this embodiment) of the protective sheet 43. For example, the control device 300 (specifically, the determination unit 320 described later) uses the detection results of the light from each of the light sensors 51A and 51B to determine whether the protective sheet 43 is properly supplied between the component 3 and the crimping tool 33 (more specifically, whether the position of the protective sheet 43 is misaligned).

[0101] The number of protective plates 43 used simultaneously by the component pressing device 100 when mounting the light sensor 51A and light sensor 51B in the fixture 52 is four in this embodiment.

[0102] The fixture 52 facilitates the positioning of the light sensor 51A and the light sensor 51B, and is a fixture for fixing the light sensor 51A and the light sensor 51B at the positioned location.

[0103] The detection unit 50 is provided, for example, between the crimping tool 33 and the supply reel 42 in the supply direction (Y-axis direction in this embodiment) where the protective sheet 43 is supplied by the protective sheet supply unit 22. Furthermore, for example, the detection unit 50 is located on the opposite side of the crimping tool 33 from the substrate 2 supported by the substrate support unit 14 in the pressing direction (Z-axis direction in this embodiment) where the crimping tool 33 presses the component 3 against the substrate 2.

[0104] Figure 5 This is a perspective view illustrating the specific detection positions of the optical sensors 51A and 51B involved in the embodiment. Additionally, in Figure 5 For illustrative purposes, only one set of light sensors 51A and 51B is shown.

[0105] Light sensors 51A and 51B are configured, for example, to emit light to both ends of the protective sheet 43 in the width direction of the protective sheet 43. Specifically, light sensor 51A emits light to one end of the protective sheet 43 in the width direction of the protective sheet 43 (e.g., Figure 5 The light emitted from the position of the light spot S1 shown is detected by the light sensor 51B at the other end of the protective sheet 43 (e.g., in the width direction of the protective sheet 43). Figure 5 The emitted light is located at the position of the light spot S2 shown.

[0106] Figure 6 This is a top view showing a first example of the specific detection position of the detection unit 50 involved in the embodiment.

[0107] In this embodiment, light from light sensor 51A is reflected at light spot S1 and detected by light sensor 51A, and light from light sensor 51B is reflected at light spot S2 and detected by light sensor 51B. Thus, when light is detected by both light sensor 51A and light sensor 51B, it is determined, for example, that the position of the protective sheet 43 has not deviated, that is, it is determined that the supply has been properly performed.

[0108] Figure 7 This is a top view showing a second example of the specific detection position of the detection unit 50 involved in the embodiment.

[0109] In this embodiment, light from the light sensor 51A is reflected at the light spot S1 and detected by the light sensor 51A. On the other hand, in this embodiment, light from the light sensor 51B does not illuminate the protective sheet 43 and therefore is not reflected at the light spot S2, and thus is not detected by the light sensor 51B. Thus, if only light from one of the light sensors 51A and 51B is not detected, it is determined, for example, that the protective sheet 43 is misaligned, that is, it is determined that the supply is not properly provided.

[0110] Furthermore, for example, it is conceivable that the light from light sensor 51A is not reflected at light spot S1 and is not detected by light sensor 51A, and the light from light sensor 51B is not reflected at light spot S2 and is not detected by light sensor 51B. In such a case, for example, the protective sheet 43 itself is not detected anywhere, and it is conceivable that the protective sheet 43 is cut off. Thus, for example, if no light is detected from either light sensor 51A or light sensor 51B, it is determined that the protective sheet 43 is cut off, that is, it is determined that the supply is not properly provided.

[0111] As described above, the detection results of the detection unit 50 are used to determine whether the protective sheet 43 is properly supplied between the component 3 and the crimping tool 33 (more specifically, whether the position of the protective sheet 43 is deviated).

[0112] Additionally, the crimping mechanism 200 may include a calibration camera. For example, a calibration camera for positioning the substrate 2 at a given location may be provided on the base 11. The calibration camera may be positioned, for example, at the same location as the detection unit 50. Furthermore, if the detection unit 50 is composed of a camera, the detection unit 50 and the calibration camera may also be implemented using the same camera (e.g., a common single camera).

[0113] Furthermore, the sensors used in the detection unit 50 (specifically, light sensors 51A and 51B) can be any type of sensor. For example, the detection unit 50 can use a laser sensor, a spot type sensor, a laser sheet sensor, a photoelectric sensor, or a fiber optic sensor. Alternatively, the detection unit 50 can use a passive sensor or a camera. Furthermore, the number of sensors in the detection unit 50 can be two (as with light sensors 51A and 51B), one, or more than three.

[0114] The control device 300 is a computer that controls the various mechanisms of the crimping mechanism 200, such as the moving mechanism, the crimping tool 33 (crimping part 21), the detection part 50, and the protective sheet supply part 22.

[0115] The control device 300 is implemented through a communication interface for communicating with the various mechanisms of the crimping mechanism 200, a non-volatile memory for storing programs, a temporary storage area (i.e., volatile memory) for executing programs, input / output ports for transmitting and receiving signals, and a processor for executing programs. The communication interface can be implemented, for example, by an antenna and wireless communication circuitry for wireless communication, or by a connector for wired communication.

[0116] The control device 300 includes a control unit 310, a determination unit 320, an output unit 330, and a storage unit 340.

[0117] The control unit 310 is a processing unit that controls the various mechanisms included in the crimping mechanism 200. Specifically, the control unit 310 controls the moving mechanism, crimping tool 33 (crimping part 21), detection unit 50, and protective sheet supply unit 22 included in the crimping mechanism 200. For example, the control unit 310 controls the supply (movement) of the protective sheet 43 by controlling the feed roller 45 included in the protective sheet supply unit 22. Furthermore, for example, the control unit 310 controls the lifting and lowering of the crimping tool 33 by controlling the lifting motor 31 and the pressure cylinder 34.

[0118] For example, the control unit 310 controls the aforementioned substrate transport device to place the substrate 2, which carries multiple components 3, onto the substrate mounting section 12a. Next, the control unit 310 controls the aforementioned moving mechanism to move the substrate mounting section 12a. For example, the control unit 310 controls the moving mechanism based on the imaging results of the calibration camera, thereby placing the end of the substrate 2 onto the substrate support section 14. Furthermore, the control unit 310 controls the protective sheet supply unit 22 to supply a protective sheet 43 between the component 3 and the crimping tool 33. Specifically, the control unit 310 controls the protective sheet supply unit 22 to supply the unused area of ​​the protective sheet 43 between the component 3 and the crimping tool 33. The unused area is the area (part) of the protective sheet 43 that has not yet been pressed by the crimping tool 33. Furthermore, the control unit 310 controls the detection unit 50 to detect the protective sheet 43. Furthermore, the control unit 310 controls the crimping unit 21 to cause the crimping tool 33 to crimp the component 3 to the substrate 2 through the protective sheet 43.

[0119] Furthermore, the control unit 310, for example, causes the crimping tool 33 to crimp the component 3 to the substrate 2 with the protective sheet 43 in a relaxed state. For example, the control unit 310 supplies the protective sheet 43 in a non-relaxed state (i.e., under tension), and during crimping, controls the protective sheet supply unit 22 to relax the protective sheet 43. For example, after the control unit 310 performs a sheet feeding operation on the protective sheet supply unit 22 to supply the unused area of ​​the protective sheet 43 between the component 3 mounted on the substrate 2 supported by the substrate support 14 and the crimping tool 33, the control unit 310 performs a relaxation generation operation on the protective sheet 43 supplied by the sheet feeding operation to relax it. Furthermore, for example, after the control unit 310 performs the relaxation generation operation on the protective sheet supply unit 22, the control unit 310 performs the crimping operation on the crimping tool 33. Here, for example, the control unit 310 performs a detection operation on the detection unit 50 after the sheet feeding operation is completed and before the relaxation generation operation begins.

[0120] The determination unit 320 is a processing unit that determines whether the position of the protective sheet 43 is deviated in the width direction of the protective sheet 43 based on the detection results of the detection unit 50.

[0121] The output unit 330 is a processing unit that outputs result information representing the determination result of the determination unit 320. For example, if the output unit 330 determines that the position of the protection piece 43 has deviated, it outputs the result information. On the other hand, if the output unit 330 determines that the position of the protection piece 43 has not deviated, it does not output the result information. Of course, the output unit 330 may also output the result information regardless of the determination result.

[0122] The result information is output to a notification device 400, such as a display, and the notification device 400 notifies the operator of the judgment result represented by the result information.

[0123] Alternatively, for example, the result information can be output to the control unit 310 or the crimping mechanism 200, and if it is determined that the position of the protective sheet 43 is deviated in the width direction, processing to eliminate the position deviation of the protective sheet 43 can be performed, or the crimping mechanism 200 can be stopped urgently.

[0124] The control unit 310, the determination unit 320, and the output unit 330 are implemented, for example, by a processor such as a CPU (Central Processing Unit) and a memory that stores the control program executed by the processor.

[0125] The storage unit 340 is a storage device that stores various types of information. For example, the storage unit 340 stores threshold information such as the pressing time used when the component 3 is pressed onto the substrate 2. The storage unit 340 is implemented, for example, by an HDD (Hard Disk Drive) or a semiconductor memory.

[0126] The notification device 400 is a device for notifying (reporting) information to an operator. For example, when result information is input, the notification device 400 notifies the operator of the judgment result represented by the result information. The notification device 400 is, for example, a display that notifies the operator of the judgment result by displaying an image representing the judgment result.

[0127] Furthermore, the notification device 400 can be any device capable of notifying the operator of information; for example, it could be an audio device equipped with a speaker. The determination result can be displayed via an image or by sound.

[0128] [Processing Steps]

[0129] Next, the processing steps 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.

[0130] Figure 8 This is a flowchart illustrating the component crimping method involved in the implementation method. Figures 9-13 This is a side view showing the operation of the crimping mechanism 200 according to the embodiment.

[0131] First, the control unit 310 places the substrate 2, on which the component 3 is mounted, into the substrate placement unit 12a. 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 into the substrate placement unit 12a.

[0132] Alternatively, this process can be performed by equipment such as a mounting system equipped with the component crimping device 100 and a control device. The substrate transport device can be provided by the component crimping device 100 or by the mounting system. Furthermore, for example, the control unit 310 moves the substrate mounting unit 12a by controlling the moving mechanism so that the component 3 is positioned below the crimping tool 33.

[0133] Next, the protective sheet supply unit 22 performs a sheet feeding operation (S110). In other words, the control unit 310 causes the protective sheet supply unit 22 to perform the sheet feeding operation. Specifically, the control unit 310 causes the protective sheet supply unit 22 to supply the protective sheet 43 between the crimping tool 33 and the component 3. For example, the control unit 310 supplies the protective sheet 43 between the crimping tool 33 and the component 3 by causing the feed roller 45 to... Figure 9 Rotate in the direction shown in A1 to supply the protective plate 43.

[0134] Next, the detection unit 50 performs a detection operation (S120). In other words, the control unit 310 causes the detection unit 50 to perform the detection operation. For example, the detection unit 50 detects the parts of the protective sheet 43 that are located differently in the width direction (X-axis direction in this embodiment) of two or more parts.

[0135] The determination unit 320 determines, based on the detection result of the detection unit 50, whether the position of the protective sheet 43 has deviated from a given position in the width direction of the protective sheet 43 (S130). For example, the detection unit 50, for example, Figure 9 As shown, it is positioned below the protective sheet 43, and the protective sheet 43 is detected by emitting light upwards.

[0136] If the determination unit 320 determines that the position has not deviated (S130 "No"), the control unit 310 moves the substrate 2 to the panel mark recognition position (S140). Specifically, the control unit 310 controls the moving mechanism to move the substrate 2 to a position where the calibration camera can recognize the panel mark (calibration mark) provided on the substrate 2. For example, the control unit 310 controls the moving mechanism to move the substrate 2 to a position where the calibration camera can capture an image of the panel mark provided at the end of the substrate 2 (e.g., a position that does not overlap with the substrate mounting portion 12a when viewed from above) from below the substrate 2. Figure 9 In the example shown, the control unit 310 moves the substrate mounting unit 12a on which the substrate 2 is mounted in the positive Y-axis direction.

[0137] Next, the control unit 310 performs the recognition process of the panel mark provided on the substrate 2 (S150). Specifically, the control unit 310 causes the calibration camera to take a picture of the panel mark provided on the substrate 2, and identifies the correct position of the substrate 2 based on the picture result.

[0138] Next, the control unit 310 moves the substrate 2 to the pressing position based on the recognition result of the panel mark recognition processing on the substrate 2. Specifically, the control unit 310 controls the moving mechanism to move the substrate 2 to a position where the end of the substrate 2 is supported by the substrate support 14 and the member 3 is pressed (thermally pressed) onto the substrate 2.

[0139] Next, the protective sheet supply unit 22 performs a relaxation generation operation (S170). Specifically, the protective sheet supply unit 22 uses the feed roller 45 to relax the protective sheet 43 located between the component 3 and the crimping tool 33. More specifically, the control unit 310 relaxes the protective sheet 43 located between the component 3 and the crimping tool 33 by controlling the feed roller 45 of the protective sheet supply unit 22. For example, the control unit 310 controls the feed roller 45 to move towards... Figure 10Rotate in the direction of A2 as shown, so that from Figure 9 The protective sheet 43 located between component 3 and crimping tool 33, as shown, is in a taut state (in other words, a state in which tension is applied to the protective sheet 43). Figure 10 The protective sheet 43, located between component 3 and crimping tool 33, is in a relaxed state, as shown.

[0140] Next, in other words, the crimping tool 33 performs the crimping action by executing steps S170 to S190. In other words, the control unit 310 causes the crimping tool 33 to perform the crimping action by causing the crimping tool 33 to execute steps S170 to S190.

[0141] First, the control unit 310 lowers the crimping tool 33 (S180). For example, the control unit 310 lowers the crimping tool 33 by means of... Figure 11 The crimping tool 33 (specifically the lifting motor 31) is controlled as shown to lower the crimping tool 33 so that the crimping tool 33 contacts the component 3 through the protective plate 43.

[0142] Next, the control unit 310 causes the crimping tool 33 to press the component 3 against the substrate 2 (S190). For example, the control unit 310 uses a method such as Figure 11 The crimping tool 33 (specifically the pressure cylinder 34) is controlled as shown to press the component 3 onto the substrate 2 through the protective sheet 43.

[0143] Next, the control unit 310 raises the crimping tool 33 (S200). For example, the control unit 310 raises the crimping tool 33 by means of... Figure 12 The crimping tool 33 (specifically the lifting motor 31 and the pressure cylinder 34) is controlled as shown to cause the crimping tool 33 to stop the component 3 from pressing the substrate 2 through the protective sheet 43, and to raise the crimping tool 33.

[0144] If the crimping action is completed, the protective sheet supply unit 22 performs a slack removal action (S210). Specifically, the protective sheet supply unit 22 uses the feed roller 45 to remove the slack in the protective sheet 43 located between the component 3 and the crimping tool 33. More specifically, the control unit 310 removes the slack by controlling the feed roller 45 of the protective sheet supply unit 22 to apply tension to the protective sheet 43 located between the component 3 and the crimping tool 33. For example, the control unit 310 controls the feed roller 45 to move towards... Figure 13 Rotate in the direction A1 as shown, so that from Figure 12 As shown, the protective sheet 43 located between component 3 and crimping tool 33 is in a relaxed state. Figure 13 The protective sheet 43, located between component 3 and crimping tool 33, is in a taut state as shown.

[0145] If the protective sheet 43 is not misaligned, the above process is repeated to press the component 3 onto the substrate 2 in sequence. The substrate 2 with the component 3 pressed onto it is transported, for example, to a downstream device (e.g., an unloading machine) via a substrate transport device.

[0146] On the other hand, if the determination unit 320 determines that there is a positional deviation (S130 "Yes"), the output unit 330 outputs result information indicating the determination result of the determination unit 320 (S220). For example, the output unit 330 notifies the operator of the determination result indicated by the result information by outputting the result information to a display device such as a monitor used by the operator. In this case, for example, the processing of the crimping mechanism 200 is temporarily stopped, and the operator adjusts the position of the protective piece 43.

[0147] Alternatively, the result information can also be output to the protective sheet supply unit 22. For example, if the protective sheet supply unit 22 receives the result information, it can perform a restoration operation to adjust the position of the protective sheet 43. For example, the protective sheet supply unit 22 can alternately perform the relaxation generation operation and the sheet feeding operation more than once. Afterwards, the process can return to step S120. For example, if such a restoration operation is performed more than a given number of times, the output unit 330 can output the result information to a display device such as a display used by the operator to notify the operator of the judgment result represented by the result information.

[0148] In addition, the number of times given can be 1 time or more than 2 times, without any particular limitation.

[0149] Furthermore, the result information can also be output to the control unit 310. For example, if the control unit 310 obtains the result information, it can cause the protection plate supply unit 22 to perform a restoration operation to adjust the position of the protection plate 43.

[0150] In addition, in step S130, the determination unit 320 may further determine whether the protective sheet 43 is cut based on the detection result of the detection unit 50.

[0151] [Effects, etc.]

[0152] The following examples illustrate techniques obtained from the disclosure of this specification and explain the effects obtained from the illustrated techniques.

[0153] Technology 1 is a component pressing apparatus 100, comprising: a substrate support 14 that supports a substrate 2; a pressing tool 33 that performs a pressing operation by pressing a component 3 mounted on the substrate 2 supported by the substrate support 14 against the substrate 2 through a protective sheet 43, thereby pressing the component 3 to the substrate 2; a protective sheet supply unit 22 that performs a sheet feeding operation that supplies a protective sheet 43 between the component 3 mounted on the substrate 2 supported by the substrate support 14 and the pressing tool 33; a detection unit 50 that performs a detection operation that detects the protective sheet 43 supplied by the sheet feeding operation; a determination unit 320 that determines, based on the detection result of the detection unit 50, whether the position of the protective sheet 43 deviates in the width direction; and an output unit 330 that outputs result information representing the determination result of the determination unit 320.

[0154] The width direction of the protective sheet 43 is, for example, the X-axis direction described above. The result information is output to a notification device 400, such as a display, and the notification device 400 informs the operator of the determination result represented by the result information. Alternatively, the result information may be output to the control unit 310 or the crimping mechanism 200. If it is determined that the position of the protective sheet 43 is deviated in the width direction, processing to eliminate the positional deviation of the protective sheet 43 may be performed, or the crimping mechanism 200 may be stopped immediately.

[0155] Accordingly, positional deviation of the protective sheet 43 in the width direction can be detected. Furthermore, in the event of positional deviation of the protective sheet 43 in the width direction, various processes can be performed based on the resulting information to eliminate such positional deviation. Therefore, the generation of quality defects in the substrate 2 to which the component 3 is pressed can be suppressed due to the pressing of the component 3 onto the substrate 2.

[0156] In the past, during crimping (specifically, hot crimping), a protective resin sheet 43 was inserted between the crimping tool 33 and the component 3 to protect against impacts to the component 3 and contaminant adhesion to the crimp joint. The position of the protective sheet 43 was changed sequentially for each crimping operation by the sheet feeding action of the feed roller 45. During this sheet feeding action, if the protective sheet 43 deviates from its intended path and moves in a zigzag manner, uneven crimping occurs, resulting in poor quality such as indentations or improper mounting on the substrate 2 where the component 3 is mounted. Therefore, the component crimping apparatus 100 uses a detection unit 50 to monitor the position of the protective sheet 43. This allows for non-invasive and real-time monitoring of the protective sheet 43. Furthermore, the detection unit 50 can also detect situations where the protective sheet 43 is cut off or absent.

[0157] Based on the component crimping device 100 described in Technology 1, Technology 2 has a protective sheet supply unit 22 comprising: a supply reel 42 that holds the protective sheet 43; and a feed roller 45 which is provided on the opposite side of the supply reel 42 relative to the crimping tool 33 in the supply direction in which the protective sheet 43 is supplied by the protective sheet supply unit 22, and performs a sheet feeding operation by drawing the protective sheet 43 out from the supply reel 42. A detection unit 50 is provided between the crimping tool 33 and the supply reel 42 in the supply direction.

[0158] The supply direction is, for example, the Y-axis direction mentioned above.

[0159] By arranging the detection unit 50 between the crimping tool 33 and the supply reel 42, the protective sheet 43 before heat crimping, i.e., the protective sheet 43 that has not been deformed by crimping, can be used as the detection object of the detection unit 50. As a result, the detection accuracy of the protective sheet 43 by the detection unit 50 can be improved.

[0160] Based on the component crimping device 100 described in Technology 2, Technology 3 has a crimping tool 33 heated by a heater 35, and a detection unit 50 located on the opposite side of the crimping tool 33 in the pressing direction in which the crimping tool 33 presses the component 3 against the substrate 2, relative to the substrate 2 supported by the substrate support unit 14.

[0161] The pressing direction is, for example, the Z-axis direction mentioned above.

[0162] Therefore, the detection unit 50 can be positioned in a location far from the crimping tool 33 heated by the heater 35. This reduces the thermal impact on the detection unit 50. Consequently, the detection accuracy of the protective plate 43 of the detection unit 50 can be improved.

[0163] Based on the component crimping device 100 described in any one of techniques 1 to 3, in technique 4, the output unit 330 outputs result information when it is determined that the position of the protective sheet 43 is deviated.

[0164] That is, the output unit 330 may not output result information if it determines that the position of the protection plate 43 has not deviated.

[0165] If the protective sheet 43 deviates in position along its width, various processes are required to eliminate this deviation. Therefore, in cases where various processes are required to eliminate the deviation, result information can be output.

[0166] Based on the component crimping apparatus 100 described in any one of techniques 1 to 4, technique 5 includes: a control unit 310 that controls the protective sheet supply unit 22, the crimping tool 33, and the detection unit 50. After the control unit 310 causes the protective sheet supply unit 22 to perform a sheet feeding operation to supply an unused area of ​​the protective sheet 43 between the component 3 mounted on the substrate 2 supported by the substrate support unit 14 and the crimping tool 33, the control unit 310 causes the protective sheet supply unit 22 to perform a relaxation generation operation to relax the protective sheet 43 supplied by the sheet feeding operation. After the protective sheet supply unit 22 performs the relaxation generation operation, the crimping tool 33 performs a crimping operation. After the sheet feeding operation is completed and before the relaxation generation operation begins, the detection unit 50 performs a detection operation.

[0167] The protective sheet 43 is supplied in an unrelaxed state (i.e., under tension), and during crimping, it is controlled to be in a relaxed state to suppress the occurrence of quality defects. However, if the inspection operation is performed with the protective sheet 43 in a relaxed state, the protective sheet 43 may not be detected correctly. Therefore, by performing the inspection operation of the inspection unit 50 after the sheet feeding operation is completed and before the relaxation generation operation begins, the inspection accuracy of the inspection unit 50 can be improved.

[0168] Technique 6 is a component crimping method. The crimping tool 33 performs a crimping action, which presses the component 3 mounted on the substrate 2 supported by the substrate support portion 14 of the supported substrate 2 against the substrate 2 through the protective sheet 43, thereby crimping the component 3 to the substrate 2 (e.g., steps S180 to S200). The protective sheet supply portion 22 performs a sheet feeding action, which supplies the protective sheet 43 between the component 3 mounted on the substrate 2 supported by the substrate support portion 14 and the crimping tool 33 (e.g., step S110). The detection portion 50 performs a detection action, which detects the protective sheet 43 supplied by the sheet feeding action (e.g., step S120). The determination portion 320 determines whether the position of the protective sheet 43 is deviated in the width direction of the protective sheet 43 based on the detection result of the detection portion 50 (e.g., S130). The output portion 330 outputs result information indicating the determination result of the determination portion 320 (e.g., step S220).

[0169] Accordingly, it achieves the same effect as the component crimping device 100 described in Technique 1.

[0170] Furthermore, these general or specific methods can be implemented by non-transitory recording media such as systems, methods, integrated circuits, computer programs, or computer-readable CD-ROMs, or by any combination of systems, methods, integrated circuits, computer programs, and recording media.

[0174] Furthermore, for example, in the above embodiments, all or part of the components of the control device 300 may be constructed by dedicated hardware, or may be implemented by executing software programs suitable for each component. Each component may be implemented by a program execution unit such as a CPU or processor reading and executing the software program recorded on a recording medium such as an HDD or semiconductor memory.
