Description

Technical Field

[0001] The present invention relates to a component crimping device and a component crimping method for crimping components onto a substrate.

Background Art

[0002] Conventionally, there has been a component crimping device for crimping components such as electronic components onto a substrate such as a display panel. In the thermocompression bonding of components to a substrate, there is a case where an implementation method is used in which a protective sheet for protecting against the impact during pressurization (pressing) by crimping is sandwiched between a crimping tool such as a crimping head and the component to be crimped to the substrate by the crimping part. Patent Document 1 discloses a component crimping device provided with a device for supplying a protective sheet.

[0003] The component crimping device disclosed in Patent Document 1 is a device that crimps (performs final crimping) a component onto a substrate by pressing a component that has been previously mounted (temporarily crimped) on the edge of the substrate against the substrate. The component is mounted on the substrate via an adhesive made of an anisotropic conductive member called ACF (Anisotropic Conductive Film). In order to prevent the ACF from adhering to the crimping tool during the crimping operation of the component, the crimping tool presses the component through a protective sheet installed below it.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The protective sheet is, for example, set in a roll and is rewound by a sheet feeding mechanism such as a reel after use. The protective sheet used to protect components when they are pressed onto the circuit board is, for example, made of resin and can wrinkle due to deformation. As a result, the protective sheet may be misaligned due to such deformation or may be fed in a direction that is tilted relative to the appropriate feeding direction (supply direction). If the protective sheet is not positioned to cover, for example, the entire component being pressed, the pressing force will vary and the component will not be pressed correctly, resulting in a defective circuit board with the component pressed onto it.

[0006] This invention provides a component crimping device and the like that can suppress the occurrence of quality defects. [Means for solving the problem]

[0008] A component crimping method according to one aspect of the present invention involves a crimping tool performing a crimping operation to press a component mounted on a substrate supported by a substrate support portion that supports the substrate toward the substrate via a protective sheet, thereby crimping the component to the substrate; a protective sheet supply unit performing a sheet feeding operation to supply the protective sheet between the component mounted on the substrate supported by the substrate support portion and the crimping tool; a detection unit performing a detection operation to detect the protective sheet supplied by the sheet feeding operation; a determination unit determining, based on the detection result of the detection unit, whether or not the protective sheet is misaligned in the width direction of the protective sheet; and an output unit outputting result information indicating the determination result of the determination unit.

Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that each of the embodiments described below shows a specific example of the present invention. Therefore, the numerical values, shapes, materials, components, arrangements and connection forms of the components, steps, and the order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. Thus, among the components in the following embodiments, the components not described in the independent claims of the present invention are described as optional components.

[0012] Also, each figure is a schematic diagram and is not necessarily drawn precisely. Therefore, for example, the scales in each figure do not necessarily match. Also, in each figure, substantially the same configurations are denoted by the same reference numerals, and overlapping descriptions are omitted or simplified.

[0013] Also, in this specification and the drawings, the X-axis, Y-axis, and Z-axis represent the three axes of a three-dimensional orthogonal coordinate system. The X-axis and Y-axis are perpendicular to each other and both are perpendicular to the Z-axis. Also, in the following embodiments, there are cases where where where where the positive direction of the Z-axis is described as upward and the negative direction of the Z-axis is described as downward.

[0014] (Embodiment) [Configuration] First, the configuration of the component crimping device according to the embodiment will be described.

[0015] FIG. 1 is a block diagram showing a component crimping device 100 according to an embodiment. FIG. 2 is a side view showing a specific configuration of a crimping mechanism 200 according to the embodiment.

[0016] The component crimping device 100 is a device for crimping (more specifically, thermocompression bonding) a component 3 to a substrate 2. The component crimping device 100 is, for example, a part of a component mounting system for producing a display panel or the like. In the 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 placed (temporarily crimped) on the substrate 2 through the anisotropic conductive film, and the temporarily crimped substrate 2 and the component 3 are thermocompression bonded. The mounting system includes, for example, an adhering device for adhering an anisotropic conductive film to the substrate 2, a temporary crimping device for placing (temporarily crimping) the component 3 on the substrate 2 through the anisotropic conductive film, and a main crimping device for thermocompression bonding (main crimping) the component 3 to the substrate 2. For example, the component crimping device 100 is the main crimping device included in the mounting system.

[0017] The component crimping device 100 mainly crimps the substrate 2 and the component 3 carried out from an upstream device (for example, a temporary crimping device) to the substrate placement portion 12a by a substrate transfer device (not shown). The substrate 2 to which the component 3 is mainly crimped is conveyed to a downstream device (for example, an unloader) by the substrate transfer device.

[0018] <> Examples of the substrate 2 include a flexible substrate made of resin or the like. Note that the substrate 2 may also be a display panel using a glass substrate or the like.

[0019] The component 3 is, for example, an electronic component such as a drive circuit. Examples of the component 3 include flexible components such as TCP (Tape Carrier Package) and FPC (Flexible Printed Circuits), or IC (Integrated Circuit) chips.

[0020] The component crimping device 100 includes a crimping mechanism 200, a control device 300, and a notification device 400.

[0021] The crimping mechanism 200 is a mechanism that heat-presses the substrate 2 and the component 3. For example, the crimping mechanism 200 heat-presses the component 3 onto the substrate 2 under the control of a control device 300 (specifically, a control unit 310). In this embodiment, the crimping mechanism 200 includes a base 11, a substrate support 14, a crimping section 21, a protective sheet supply section 22, and a detection section 50. The crimping section 21 includes a lifting motor 31, a lifting base 32, a crimping tool 33, a pressure cylinder 34, and a heater 35.

[0022] Furthermore, a touch panel, which serves as an input / output device for the operator, may be placed on the negative Y-axis side of the base 11.

[0023] The substrate mounting section 12a is a stage (table) on which a substrate 2 with multiple components 3 mounted (arranged) is placed. Specifically, a substrate 2 with components 3 arranged via an anisotropic conductive film is placed on the substrate mounting section 12a. For example, a substrate 2 transported by the substrate transport device described above is placed on the substrate mounting section 12a with the edges on which the components 3 are mounted protruding. Thus, the substrate mounting section 12a has a holding surface on which the substrate 2 is placed with its outer edge protruding from the substrate mounting section 12a (more specifically, with the edges not overlapping the substrate mounting section 12a when viewed from above). The edges of the substrate 2 are supported by the substrate support section 14 when components 3 are pressed onto the substrate 2. The substrate support section 14 is a backup stage that supports the substrate 2. Specifically, the substrate support section 14 supports the edges of the substrate 2 from below.

[0024] The substrate mounting section 12a may be provided with a suction mechanism for adsorbing the substrate 2 on its holding surface. For example, an opening (e.g., a through hole) is formed in the holding surface, and the substrate mounting section 12a holds the substrate 2 by adsorption on its holding surface. For example, a suction device may be connected to the opening to draw air in, thereby drawing in the substrate 2 on its holding surface, and the substrate 2 may be held by adsorption on its holding surface as the suction device draws in air. The suction mechanism may include, for example, a vacuum pump for drawing in air, vacuum piping connecting the vacuum pump and the opening, and a valve for controlling the suction.

[0025] The control unit 310, described later, controls the valve to switch whether or not to generate an adhesive force on the holding surface by the suction mechanism, that is, whether or not to allow the edge of the substrate 2 to be adsorbed by the suction mechanism.

[0026] The valves in the adsorption mechanism may be, for example, solenoid valves for switching air intake on and off, or pressure regulating valves (so-called pressure regulators) for switching the suction force (adsorption force).

[0027] Alternatively, the substrate mounting portion 12a may not have the aforementioned openings on its holding surface, and the substrate 2 may be held by the holding surface simply by being placed on it.

[0028] The substrate mounting section 12a is provided so as to be movable by, for example, 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 three-axis stage. The moving mechanism is implemented, for example, by a conveyor configured to allow the substrate mounting section 12a to move arbitrarily in the XY plane and to move up and down in the Z axis direction.

[0029] The crimping section 21 includes a lifting base 32 that moves up and down by the operation of a lifting motor 31. The lifting base 32 is provided with a plurality of crimping tools 33. In this embodiment, the crimping section 21 is equipped with six crimping tools 33.

[0030] The crimping tool 33 is a crimping head that performs a crimping operation to press components 3 mounted on a substrate 2 supported by a substrate support 14 toward the substrate 2 via a protective sheet 43, thereby crimping the components 3 to the substrate 2. Multiple crimping tools 33 perform a pressing operation, that is, a crimping operation, to press each of the multiple components 3 toward the substrate 2 via the protective sheet 43, thereby crimping the components 3 to the substrate 2. Each crimping tool 33 is arranged 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 provided in conjunction with each crimping tool 33. Each crimping tool 33 has a built-in heater 35. The crimping tool 33 is heated by the heater 35 before use.

[0031] The heater 35 is a heater for heating the crimping tool 33. The heater 35 heats the crimping tool 33, causing the crimping tool 33 to press the component 3 against the substrate 2, thereby thermally bonding the component 3 to the substrate 2. The heater 35 can be implemented, for example, by an electric heating wire or a Peltier element.

[0032] 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 protective sheet feeding operation (also simply called a sheet feeding operation) that supplies 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.

[0033] Figure 3 is a perspective view showing the specific configuration of the protective sheet supply unit 22 according to the embodiment.

[0034] The protective sheet supply unit 22 comprises a case 41, a plurality of supply reels 42, a guide roller 44, a feed roller 45, a press roller 46, and a drive motor 47.

[0035] The protective sheet supply unit 22 is equipped with multiple supply reels 42 (four in this embodiment, corresponding to the number of crimping tools 33) within the case 41 that forms the outer casing.

[0036] The supply reels 42 are reels that hold the protective sheets 43. Each supply reel 42 holds the protective sheet 43 in a rolled state and is installed inside the case 41, aligned in the X-axis direction with its rotation axis facing the X-axis direction. Multiple guide rollers 44 are provided in the central part of the case 41 in the Y-axis direction. In addition, one feed roller 45 and multiple (four in this embodiment, corresponding to the number of supply reels 42) press rollers 46 are provided on the positive Y-axis side of the case 41.

[0037] Multiple guide rollers 44 guide the protective sheets 43, which are pulled out from each supply reel 42 in the positive Y-axis direction, so that they are in a nearly horizontal position in the central part of the case 41. This central part, located directly below the crimping tool 33, is the part where the part 3 is pressed by the crimping tool 33 via the protective sheet 43 when the part 3 is pressed by the crimping tool 33, as described later.

[0038] The feed roller 45 is a roller that performs a sheet feeding operation for multiple protective sheets 43 drawn from each of the multiple supply reels 42 in a single operation. Specifically, the feed roller 45 is located on the opposite side of the supply reels 42 from the crimping tool 33 in the supply direction in which the protective sheets 43 are supplied by the protective sheet supply unit 22, and performs a sheet feeding operation by drawing the protective sheets 43 from the supply reels 42. The feed roller 45 is in contact with each of the multiple protective sheets 43 and is rotated by the drive motor 47 to perform a sheet feeding operation for the multiple protective sheets 43. In this embodiment, the operation in which the feed roller 45 rotates in contact with each of the multiple protective sheets 43 is referred to as the sheet feeding operation.

[0039] The feed roller 45 is positioned with its rotation axis oriented in the X-axis direction and is in contact with a portion of the protective sheet 43 that is even further in the positive Y-axis direction than the guide roller 44, which is located furthest towards the positive Y-axis direction.

[0040] The pressing rollers 46 are pinch rollers that, together with the feed rollers 45, sandwich the protective sheets 43. Multiple pressing rollers 46 (four pressing rollers 46 in this embodiment) press each of the multiple protective sheets 43 (four protective sheets 43 in this embodiment) against the feed rollers 45. The four pressing rollers 46 are positioned on the positive Y-axis side of the feed rollers 45, and are arranged in a line along the X-axis with their rotation axes facing the X-axis. Each pressing roller 46 is biased towards the positive Y-axis side by, for example, a biasing spring attached to the case 41, thereby pressing the protective sheets 43 against the feed rollers 45 and ensuring close contact.

[0041] Outside the case 41, a drive motor 47 is provided as a roller drive means for rotating the feed roller 45. When the drive motor 47 rotates the feed roller 45 around the X axis, the protective sheet 43 is pulled in the positive Y direction by the feed roller 45, pulled out from the supply reel 42, and fed in the positive Y direction. The protective sheet 43 that has passed the feed roller 45 is not wound up by the feed roller 45, but is guided below the feed roller 45 and discharged below the case 41.

[0042] In the crimping operation of part 3 by the crimping mechanism 200, first, the drive motor 47 controlled by the control unit 310 rotates the feed roller 45 so that the portion of the protective sheet 43 pulled out from each supply reel 42 that is pressed by the crimping tool 33 is an unused portion.

[0043] 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. Once each crimping tool 33 is in its initial position, the control unit 310 moves the substrate mounting section 12a holding the substrate 2 using a moving mechanism, positioning the substrate 2 so that the components 3 pre-mounted on the substrate 2 via the anisotropic conductive film are positioned below the corresponding crimping tool 33 (in other words, above the substrate support section 14).

[0044] Once the substrate 2 is positioned, the control unit 310 controls the pressure cylinder 34 to push down the multiple crimping tools 33 from their initial positions. As a result, the multiple crimping tools 33 descend from above the protective sheet 43 and press the component 3 against the substrate 2 together with the protective sheet 43. During this pressing, the component 3 is pressed against the substrate support 14 along with the substrate 2, and the anisotropic conductive film is heated through the component 3 by a heater 35 built into the crimping tool 33. As a result, the component 3 is heat-pressed (finally pressed) onto the substrate 2. When the component 3 is pressed onto the substrate 2 by the crimping tool 33, the protective sheet 43 is interposed between the crimping tool 33 and the component 3, so the crimping tool 33 does not come into contact with the anisotropic conductive film, and no part of the anisotropic conductive film adheres to the crimping tool 33.

[0045] When the crimping tool 33 presses the component 3 onto the substrate 2, the control unit 310 controls the pressure cylinder 34 to raise the crimping tool 33 and return it to its initial position. Once 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 pull out a predetermined amount (length) of protective sheet 43 from the supply reel 42, thereby performing a protective sheet 43 refresh operation. In the refresh operation, the control unit 310 controls the protective sheet supply unit 22 to feed multiple protective sheets 43 in the positive Y-axis direction and rotates the feed roller 45 at a preset rotation angle so that unused portions of the protective sheets 43 become new pressing areas. After the protective sheet 43 refresh operation is completed, the positioning of the substrate 2 and the pressing of the component 3 by the crimping tool 33 are repeatedly performed as described above.

[0046] In this embodiment, the detection unit 50 performs a detection operation to detect the protective sheet 43 supplied between the component 3 and the crimping tool 33.

[0047] Figure 4 is a perspective view showing the specific configuration of the detection unit 50 according to the embodiment.

[0048] The detection unit 50 is a device that performs a detection operation to detect the protective sheet 43 supplied by the sheet feeding operation performed by the protective sheet supply unit 22.

[0049] The detection unit 50 is implemented by an active sensor that emits light such as infrared light and detects the reflected light from the protective sheet 43.

[0050] In this embodiment, the detection unit 50 includes an optical sensor 51A, an optical sensor 51B, and a jig 52.

[0051] The optical sensors 51A and 51B are active sensors that emit light and detect reflected light from the protective sheet 43. For example, the detection operation for one protective sheet 43 is performed using the two optical sensors, 51A and 51B.

[0052] The optical sensors 51A and 51B are arranged to emit light from below the protective sheet 43, for example, and to detect the reflected light from the protective sheet 43. For example, the optical sensors 51A and 51B are arranged side by side in the width direction (in this embodiment, the X-axis direction) of the protective sheet 43. For example, the control device 300 (specifically, the determination unit 320 described later) uses the light detection results of the optical 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 protective sheet 43 is misaligned).

[0053] The sets of light sensors 51A and 51B are mounted on the jig 52 in numbers equal to the number of protective sheets 43 used simultaneously by the component crimping device 100 (four in this embodiment).

[0054] The jig 52 facilitates the positioning of the optical sensors 51A and 51B, and fixes the optical sensors 51A and 51B in the positioned locations.

[0055] 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) when the protective sheet supply unit 22 supplies the protective sheet 43. Alternatively, the detection unit 50 is provided, for example, 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) when the crimping tool 33 presses the component 3 toward the substrate 2.

[0056] Figure 5 is a perspective view illustrating the specific detection positions of the optical sensors 51A and 51B according to the embodiment. Note that in Figure 5, only one set of optical sensors 51A and 51B is shown for illustrative purposes.

[0057] The light sensors 51A and 51B are arranged, for example, to emit light at both ends of the protective sheet 43 in the width direction of the protective sheet 43. Specifically, the light sensor 51A emits light at one end of the protective sheet 43 in the width direction of the protective sheet 43 (for example, at the position of spot S1 shown in Figure 5), and the light sensor 51B emits light at the other end of the protective sheet 43 in the width direction of the protective sheet 43 (for example, at the position of spot S2 shown in Figure 5).

[0058] Figure 6 is a plan view showing a first example of a specific detection position of the detection unit 50 according to the embodiment.

[0059] In this embodiment, light from the light sensor 51A is reflected by spot S1 and detected by light sensor 51A, and light from the light sensor 51B is reflected by spot S2 and detected by light sensor 51B. When light is detected by both light sensor 51A and light sensor 51B in this way, it is determined, for example, that the protective sheet 43 is not misaligned, that is, that it is being supplied properly.

[0060] Figure 7 is a plan view showing a second example of a specific detection position of the detection unit 50 according to the embodiment.

[0061] In this embodiment, light from the optical sensor 51A is reflected by spot S1 and detected by optical sensor 51A. On the other hand, in this embodiment, light from optical sensor 51B is not irradiated onto the protective sheet 43 and is therefore not reflected by spot S2 and is not detected by optical sensor 51B. In this way, if only the light from one of the optical sensors 51A and 51B is not detected, it is determined, for example, that the protective sheet 43 is misaligned, that is, not being supplied properly.

[0062] Furthermore, it is conceivable that, for example, light from the optical sensor 51A may not be reflected at spot S1 and therefore not detected by the optical sensor 51A, and light from the optical sensor 51B may not be reflected at spot S2 and therefore not detected by the optical sensor 51B. In such cases, for example, the protective sheet 43 itself may not be detected anywhere, and it may be assumed that the protective sheet 43 has been cut. Thus, for example, if light from both the optical sensor 51A and the optical sensor 51B is not detected, it is determined that, for example, the protective sheet 43 has been cut, that is, that it has not been supplied properly.

[0063] As described above, the detection result from the detection unit 50 is used to determine whether or not the protective sheet 43 is properly supplied between the part 3 and the crimping tool 33 (more specifically, whether or not the protective sheet 43 is misaligned).

[0064] The crimping mechanism 200 may also be equipped with an alignment camera. For example, the base 11 is equipped with an alignment camera for positioning the substrate 2 at a predetermined location. The alignment camera is positioned, for example, in the same location as the detection unit 50. If the detection unit 50 is composed of a camera, the detection unit 50 and the alignment camera may be implemented with the same camera (for example, a single common camera).

[0065] Furthermore, any sensor may be used in the detection unit 50 (specifically, the optical sensor 51A and optical sensor 51B). For example, the detection unit 50 may employ a laser sensor, a spot-type sensor, a laser sheet sensor, a photoelectric sensor, or a fiber sensor. The detection unit 50 may also employ a passive sensor or a camera. In addition, the number of sensors provided in the detection unit 50 may be two, such as optical sensor 51A and optical sensor 51B, one, or three or more.

[0066] The control device 300 is a computer that controls each of the mechanisms of the crimping mechanism 200, including the moving mechanism, the crimping tool 33 (crimping section 21), the detection section 50, and the protective sheet supply section 22.

[0067] The control device 300 is implemented by a communication interface for communicating with each mechanism of the crimping mechanism 200, a non-volatile memory where the program is stored, a volatile memory which is a temporary storage area for executing the program, input / output ports for sending and receiving signals, and a processor for executing the program. The communication interface may be implemented, for example, by an antenna and a wireless communication circuit to enable wireless communication, or by a connector to which a communication line is connected to enable wired communication.

[0068] The control device 300 comprises a control unit 310, a determination unit 320, an output unit 330, and a storage unit 340.

[0069] The control unit 310 is a processing unit that controls each mechanism of the crimping mechanism 200. Specifically, the control unit 310 controls the moving mechanism, crimping tool 33 (crimping section 21), detection unit 50, and protective sheet supply unit 22 of 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 of the protective sheet supply unit 22. Also, for example, the control unit 310 controls the raising and lowering of the crimping tool 33 by controlling the lifting motor 31 and the pressure cylinder 34.

[0070] For example, the control unit 310 controls the substrate transport device to place the substrate 2, on which multiple components 3 are mounted, onto the substrate mounting section 12a. Next, the control unit 310 controls the movement mechanism to move the substrate mounting section 12a. For example, the control unit 310 controls the movement mechanism based on the imaging results of the alignment camera to place the edge of the substrate 2 onto the substrate support section 14. Furthermore, the control unit 310 controls the protective sheet supply section 22 to supply a protective sheet 43 between the components 3 and the crimping tool 33. Specifically, the control unit 310 controls the protective sheet supply section 22 to supply an unused area of ​​the protective sheet 43 between the components 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 section 50 to cause the detection section 50 to detect the protective sheet 43. Furthermore, the control unit 310 controls the crimping unit 21 to cause the crimping tool 33 to press the component 3 to the substrate 2 via the protective sheet 43.

[0071] Furthermore, the control unit 310, for example, causes the component 3 to be pressed onto the substrate 2 via the protective sheet 43 by the crimping tool 33 while the protective sheet 43 is loosened. For example, the control unit 310 may supply the protective sheet 43 when it is not loose (i.e., under tension), and then control the protective sheet supply unit 22 so that the protective sheet 43 becomes loose when crimping is performed. For example, the control unit 310 may cause the protective sheet supply unit 22 to perform a sheet feeding operation to supply the 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, and then cause the protective sheet supply unit 22 to perform a slack generation operation to create slack in the protective sheet 43 supplied by the sheet feeding operation. Alternatively, for example, the control unit 310 may cause the crimping tool 33 to perform a crimping operation after causing the protective sheet supply unit 22 to perform the slack generation operation. Here, the control unit 310 causes the detection unit 50 to perform a detection operation, for example, after the completion of the sheet feeding operation and before the start of the slack generation operation.

[0072] The determination unit 320 is a processing unit that determines whether or not the protective sheet 43 is misaligned in the width direction of the protective sheet 43 based on the detection result of the detection unit 50.

[0073] The output unit 330 is a processing unit that outputs result information indicating the determination result of the determination unit 320. For example, the output unit 330 outputs result information when it is determined that the protective sheet 43 is misaligned. On the other hand, for example, the output unit 330 does not output result information when it is determined that the protective sheet 43 is not misaligned. Of course, the output unit 330 may output result information regardless of the determination result.

[0074] The result information is output to a notification device 400, such as a display, and the operator is notified of the judgment result indicated by the result information by the notification device 400.

[0075] Alternatively, for example, if result information is output to the control unit 310 or the crimping mechanism 200 and it is determined that the protective sheet 43 is misaligned in the width direction of the protective sheet 43, then processing to correct the misalignment of the protective sheet 43 is performed, or the crimping mechanism 200 is stopped immediately.

[0076] 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.

[0077] The memory unit 340 is a storage device that stores various types of information. For example, the memory unit 340 stores threshold information such as the crimping time used when crimping component 3 to substrate 2. The memory unit 340 is implemented, for example, by an HDD (Hard Disk Drive) or semiconductor memory.

[0078] The notification device 400 is a device for notifying the operator of information. For example, when result information is input, the notification device 400 notifies the operator of the judgment result indicated by the result information. The notification device 400 is, for example, a display and notifies the operator of the judgment result by displaying an image indicating the judgment result.

[0079] The notification device 400 can be any device capable of notifying the operator of information, and may be, for example, an audio device equipped with a speaker. The judgment result may be shown as an image or by sound.

[0080] [Processing Procedure] Next, the processing procedure of the component crimping device 100 according to the embodiment will be described. The component crimping device 100 performs, for example, the component crimping method shown below.

[0081] Figure 8 is a flowchart showing a component crimping method according to an embodiment. Figures 9 to 13 are side views showing the operation of the crimping mechanism 200 according to an embodiment.

[0082] First, the control unit 310 places the substrate 2 on which the components 3 are mounted onto the substrate mounting section 12a. Specifically, the control unit 310 receives the substrate 2 from an upstream device (for example, a temporary crimping device) by controlling a substrate transport device (not shown), and places the received substrate 2 onto the substrate mounting section 12a.

[0083] This process may also be performed by the equipment and control devices of the mounting system that includes the component crimping device 100. The substrate transport device may be provided by the component crimping device 100 or by the mounting system. For example, the control unit 310 moves the substrate mounting section 12a by controlling the moving mechanism so that the component 3 is positioned below the crimping tool 33.

[0084] 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 a 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 part 3. For example, the control unit 310 supplies the protective sheet 43 by rotating the feed roller 45 in the A1 direction shown in Figure 9.

[0085] Next, the detection unit 50 performs a detection operation (S120). In other words, the control unit 310 causes the detection unit 50 to perform a detection operation. For example, the detection unit 50 detects two or more locations in the width direction (in this embodiment, the X-axis direction) of the protective sheet 43 that are at different positions from each other.

[0086] The determination unit 320 determines, based on the detection result of the detection unit 50, whether or not the protective sheet 43 is misaligned from a predetermined position in the width direction of the protective sheet 43 (S130). For example, as shown in Figure 9, the detection unit 50 is positioned below the protective sheet 43 and detects the protective sheet 43 by emitting light upwards.

[0087] If the determination unit 320 determines that there is no misalignment (No in S130), the control unit 310 moves the substrate 2 to the panel mark recognition position (S140). Specifically, the control unit 310 moves the substrate 2 to a position where the panel marks (alignment marks) provided on the substrate 2 can be recognized by the alignment camera by controlling the movement mechanism. For example, the control unit 310 moves the substrate 2 to a position where the alignment camera can image the panel marks provided on the edge of the substrate 2 (for example, a position that does not overlap with the substrate mounting section 12a in a top view) from below the substrate 2 by controlling the movement mechanism. In the example shown in Figure 9, the control unit 310 moves the substrate mounting section 12a on which the substrate 2 is mounted in the positive Y-axis direction.

[0088] Next, the control unit 310 performs a recognition process for the panel marks provided on the substrate 2 (S150). Specifically, the control unit 310 causes the alignment camera to capture images of the panel marks provided on the substrate 2, and recognizes the precise position of the substrate 2 based on the imaging results.

[0089] Next, the control unit 310 moves the substrate 2 to the crimping position based on the recognition result of the panel mark recognition process on the substrate 2 (S160). Specifically, the control unit 310 controls the moving mechanism to support the end of the substrate 2 with the substrate support part 14 and moves the substrate 2 to a position for crimping (thermo-pressing) the component 3 to the substrate 2.

[0090] Next, the protective sheet supply unit 22 performs a slack generation operation (S170). Specifically, the protective sheet supply unit 22 uses the feed roller 45 to slacken the protective sheet 43 located between the part 3 and the crimping tool 33. More specifically, the control unit 310 slackens the protective sheet 43 located between the part 3 and the crimping tool 33 by controlling the feed roller 45 of the protective sheet supply unit 22. For example, as shown in Figure 9, the control unit 310 controls the feed roller 45 to rotate in the direction A2 shown in Figure 10 so that the protective sheet 43 located between the part 3 and the crimping tool 33 is in a taut state (in other words, under tension) and becomes slack, as shown in Figure 10.

[0091] Next, in other words, the crimping tool 33 performs a crimping operation by executing steps S170 to S190. In other words, the control unit 310 causes the crimping tool 33 to perform a crimping operation by having it execute steps S170 to S190.

[0092] First, the control unit 310 lowers the crimping tool 33 (S180). For example, as shown in Figure 11, the control unit 310 lowers the crimping tool 33 (specifically, the lifting motor 31) to bring the crimping tool 33 into contact with the component 3 via the protective sheet 43.

[0093] Next, the control unit 310 causes the crimping tool 33 to press the component 3 toward the substrate 2 (S190). For example, as shown in Figure 11, the control unit 310 controls the crimping tool 33 (specifically, the pressure cylinder 34) to cause the crimping tool 33 to press the component 3 toward the substrate 2 via the protective sheet 43.

[0094] Next, the control unit 310 raises the crimping tool 33 (S200). For example, as shown in Figure 12, the control unit 310 controls the crimping tool 33 (specifically, the lifting motor 31 and the pressurizing cylinder 34) to stop the crimping of the component 3 to the substrate 2 via the protective sheet 43, and raises the crimping tool 33.

[0095] Once the crimping operation is complete, the protective sheet supply unit 22 performs a slack removal operation (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 part 3 and the crimping tool 33. More specifically, the control unit 310 controls the feed roller 45 of the protective sheet supply unit 22 to apply tension to the protective sheet 43 located between the part 3 and the crimping tool 33 and remove the slack. For example, the control unit 310 controls the feed roller 45 so that it rotates in the direction A1 shown in Figure 13, from a state where the protective sheet 43 located between the part 3 and the crimping tool 33 is slack, as shown in Figure 12, to a state where the protective sheet 43 located between the part 3 and the crimping tool 33 is taut, as shown in Figure 13.

[0096] If the protective sheet 43 is not misaligned, the above process is repeated so that the components 3 are sequentially pressed onto the substrate 2. The substrate 2 with the components 3 pressed onto it is then transported, for example, by a substrate transport device to a downstream device (for example, an unloader).

[0097] On the other hand, if the determination unit 320 determines that there is a misalignment (Yes in S130), 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 display used by the operator. In this case, for example, the processing of the crimping mechanism 200 is temporarily suspended, and the operator adjusts the position of the protective sheet 43.

[0098] The result information may also be output to, for example, the protective sheet supply unit 22. For example, when the protective sheet supply unit 22 acquires the result information, it may perform a recovery operation to adjust the position of the protective sheet 43. For example, the protective sheet supply unit 22 may alternately perform a slack generation operation and a sheet feeding operation once or more times. After that, the process may return to step S120. For example, if such a recovery operation is performed a predetermined number of times or more, the output unit 330 may notify the operator of the judgment result indicated by the result information by outputting the result information to a display device such as a display used by the operator.

[0099] The number of times specified may be one, two or more, and is not particularly limited.

[0100] Furthermore, the result information may be output to the control unit 310. For example, when the control unit 310 acquires the result information, it may cause the protective sheet supply unit 22 to perform a recovery operation to adjust the position of the protective sheet 43.

[0101] Furthermore, in step S130, the determination unit 320 may further determine whether or not the protective sheet 43 has been cut based on the detection result of the detection unit 50.

[0102] [Effects, etc.] The following describes examples of technologies that can be obtained from the disclosures in this specification, and explains the effects that can be obtained from these examples.

[0103] Technology 1 is a component crimping device 100 comprising: a substrate support section 14 that supports a substrate 2; a crimping tool 33 that performs a crimping operation to press a component 3 mounted on the substrate 2 supported by the substrate support section 14 toward the substrate 2 via a protective sheet 43; a protective sheet supply section 22 that performs a sheet feeding operation to supply the protective sheet 43 between the component 3 mounted on the substrate 2 supported by the substrate support section 14 and the crimping tool 33; a detection section 50 that performs a detection operation to detect the protective sheet 43 supplied by the sheet feeding operation; a determination section 320 that determines whether or not the protective sheet 43 is misaligned in the width direction of the protective sheet 43 based on the detection result of the detection section 50; and an output section 330 that outputs result information indicating the determination result of the determination section 320.

[0104] The width direction of the protective sheet 43 is, for example, the X-axis direction as described above. The result information is output to a notification device 400, such as a display, and the operator is notified of the determination result indicated by the result information by the notification device 400. Alternatively, for example, the result information is output to the control unit 310 or the crimping mechanism 200, and if it is determined that the protective sheet 43 is misaligned in the width direction of the protective sheet 43, processing is performed to correct the misalignment of the protective sheet 43, or the crimping mechanism 200 is stopped immediately.

[0105] According to this, misalignment of the protective sheet 43 in the width direction can be detected. Furthermore, if the protective sheet 43 is misaligned in the width direction, various processes can be performed to correct such misalignment based on the result information. As a result, the occurrence 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.

[0106] Conventionally, during crimping (specifically, during heat crimping), a protective sheet 43, for example made of resin, is inserted between the crimping tool 33 and the component 3 to protect the component 3 from impact and from dirt adhering to the crimping head. The sheet feeding operation by the feed roller 45 changes the location of the protective sheet 43 sequentially with each crimping operation. If the protective sheet 43 deviates from its intended path and moves in a meandering manner during this sheet feeding operation, crimping irregularities occur, resulting in quality defects such as poor indentation or poor mounting on the substrate 2 on which the component 3 is mounted. Therefore, the component crimping device 100 monitors the position of the protective sheet 43 using a detection unit 50. This allows for non-invasive and real-time monitoring of the protective sheet 43. Furthermore, the detection unit 50 can also detect when the protective sheet 43 is missing, such as when it has been cut.

[0107] Technology 2 is a component crimping device 100 as described in Technology 1, wherein the protective sheet supply unit 22 includes a supply reel 42 that holds the protective sheet 43, and a feed roller 45 that is provided on the opposite side of the supply reel 42 from 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 pulling the protective sheet 43 out from the supply reel 42, and the detection unit 50 is provided between the crimping tool 33 and the supply reel 42 in the supply direction.

[0108] The supply direction is, for example, the Y-axis direction as described above.

[0109] By positioning the detection unit 50 between the crimping tool 33 and the supply reel 42, the detection unit 50 can detect the protective sheet 43 before heat crimping, that is, the protective sheet 43 that has not been deformed by crimping. Therefore, the detection accuracy of the protective sheet 43 by the detection unit 50 can be improved.

[0110] Technology 3 is a component crimping device 100 as described in Technology 2, wherein the crimping tool 33 is heated by a heater 35, and the detection unit 50 is provided on the opposite side of the crimping tool 33 from the substrate 2, which is supported by the substrate support unit 14, in the pressing direction in which the crimping tool 33 presses the component 3 toward the substrate 2.

[0111] The direction of pressure is, for example, the Z-axis direction as described above.

[0112] According to this, the detection unit 50 can be positioned at a distance from the crimping tool 33 heated by the heater 35. Therefore, the thermal influence on the detection unit 50 can be reduced. As a result, the detection accuracy of the protective sheet 43 by the detection unit 50 can be improved.

[0113] Technology 4 is a component crimping device 100 according to any one of technologies 1 to 3, wherein the output unit 330 outputs result information when it is determined that the protective sheet 43 is misaligned.

[0114] In other words, the output unit 330 does not need to output result information if it determines that the protective sheet 43 is not misaligned.

[0115] If the protective sheet 43 is misaligned in the width direction, various processes are necessary to correct such misalignment. Therefore, according to this, result information can be output when various processes are necessary to correct misalignment.

[0116] Technology 5 is a component crimping device 100 according to any one of Technologies 1 to 4, comprising a control unit 310 that controls a protective sheet supply unit 22, a crimping tool 33, and a detection unit 50, wherein the control unit 310 causes the protective sheet supply unit 22 to perform a sheet feeding operation to supply unused areas 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, then causes the protective sheet supply unit 22 to perform a slack generation operation to create slack in the protective sheet 43 supplied by the sheet feeding operation, after the protective sheet supply unit 22 has performed the slack generation operation, then causes the crimping tool 33 to perform a crimping operation, and after the completion of the sheet feeding operation and before the start of the slack generation operation.

[0117] The protective sheet 43 is supplied in a non-slack state (i.e., under tension), and when crimping is performed, it is controlled to become slack in order to suppress the occurrence of quality defects. However, if the detection operation is performed when the protective sheet 43 is slack, the protective sheet 43 may not be detected accurately. Therefore, by having the detection unit 50 perform the detection operation after the completion of the sheet feeding operation and before the start of the slack generation operation, the detection accuracy of the detection unit 50 can be improved.

[0118] Technology 6 is a component crimping method in which a crimping tool 33 performs a crimping operation to crimp a component 3 mounted on a substrate 2 supported by a substrate support part 14 that supports the substrate 2 toward the substrate 2 via a protective sheet 43 (for example, steps S180 to S200), a protective sheet supply unit 22 performs a sheet feeding operation to supply a protective sheet 43 between the component 3 mounted on the substrate 2 supported by the substrate support part 14 and the crimping tool 33 (for example, step S110), a detection unit 50 performs a detection operation to detect the protective sheet 43 supplied by the sheet feeding operation (for example, step S120), a determination unit 320 determines whether or not the protective sheet 43 is misaligned in the width direction of the protective sheet 43 based on the detection result of the detection unit 50 (for example, S130), and an output unit 330 outputs result information indicating the determination result of the determination unit 320 (for example, step S220).

[0119] According to this, the same effect as the component crimping device 100 described in Technology 1 is achieved.

[0120] These comprehensive or specific embodiments may be implemented as a system, method, integrated circuit, computer program, or non-temporary recording medium such as a computer-readable CD-ROM, or as any combination of a system, method, integrated circuit, computer program, and recording medium.

[0123] Furthermore, for example, in the above embodiment, all or part of the components of the control device 300 may be made up of dedicated hardware, or they may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or processor reading and executing a software program recorded on a recording medium such as an HDD or semiconductor memory.

[0124] Furthermore, the components of the control device 300 may consist of one or more electronic circuits. Each of these one or more electronic circuits may be a general-purpose circuit or a dedicated circuit.

While referred to here as ICs or LSIs, the terminology may vary depending on the degree of integration; they might also be called system LSIs, VLSIs (Very Large Scale Integrations), or ULSIs (Ultra Large Scale Integrations).
