Summary of the Invention

Problems to be Solved by the Invention

[0004] A component crimping device, for example, pulls out a protective sheet held on a supply reel in a roll shape from the supply reel and supplies the pulled-out protective sheet above the component. Here, the protective sheet may become charged (peeling charge) when pulled out from the supply reel. When a component is crimped onto a substrate using such a charged protective sheet, the substrate is damaged by the static electricity generated due to the charging of the protective sheet.

[0005] The present invention provides a component crimping device and the like that can suppress damage to the substrate due to static electricity.

Means for Solving the Problems

[0006] A component crimping device according to one aspect of the present invention includes a substrate support portion that supports a substrate, a crimping tool that crimps a component onto the substrate supported by the substrate support portion, a sheet supply mechanism that supplies a sheet between the crimping tool and the component, a charge amount measurement portion that measures the charge amount of the sheet, and a control portion that controls the sheet supply mechanism and the crimping tool. The control portion controls the supply of the sheet by the sheet supply mechanism based on the charge amount of the sheet measured by the charge amount measurement portion, and causes the crimping tool to press the component together with the sheet supplied by the sheet supply mechanism onto the substrate, thereby crimping the component onto the substrate.

[0007] Also, a component crimping method according to one aspect of the present invention includes a substrate support step of supporting a substrate with a substrate support portion, a sheet supply step of supplying a sheet between a crimping tool and a component, a crimping step of crimping the component onto the substrate supported by the substrate support portion by causing the crimping tool to press the component together with the sheet supplied in the sheet supply step onto the substrate, and a charge amount measurement step of measuring the charge amount of the sheet. In the sheet supply step, the supply of the sheet is controlled based on the charge amount of the sheet measured in the charge amount measurement step.

[0008] These general or specific aspects may be implemented by a system, a method, an integrated circuit, a computer program, or a recording medium such as a computer-readable CD-ROM, or may be implemented by any combination of a system, a method, an integrated circuit, a computer program, and a recording medium.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, the component crimping device and the like according to the embodiment 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. Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the most general concept of the present invention are described as optional components.

[0012] Also, each figure is a schematic diagram and is not necessarily drawn precisely. In each figure, the same reference numerals are given to the same constituent members.

[0013] (Embodiment) [Configuration] First, the configuration of the component crimping device according to the embodiment will be described.

[0014] FIG. 1 is a schematic diagram of a component crimping device 100 according to an embodiment.

[0015] In FIG. 1, the computer 90 is illustrated as a functional block.

[0016] The component crimping device 100 is a device that crimps a component 300 onto a substrate 200. 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 attaching device (not shown) attaches an ACF (Anisotropic Conductive Film) to an electrode portion provided on the substrate 200, and a temporary crimping device (not shown) temporarily crimps the substrate 200 and the component 300 via the ACF. The component crimping device 100 crimps the component 300 onto the substrate 200 on which the component 300 is disposed (placed), which is conveyed from an upstream device (for example, a temporary crimping device) by a substrate conveying device (not shown). The substrate 200 to which the component 300 is crimped is conveyed, for example, downstream of the component crimping device 100 by the substrate conveying device.

[0017] Examples of the substrate 200 include a film-like flexible substrate formed of resin or the like, or a rigid substrate such as a glass substrate.

[0018] Examples of the component 300 include electronic components such as an IC (Integrated Circuit), a TCP (Tape Carrier Package), and an FPC (Flexible Printed Circuits).

[0019] As shown in FIG. 1, the component crimping device 100 includes a sheet holding portion 20, a feed roller 21, a crimping head 50, a motor 51, a guide 52, a stage 70, a backup stage 80, a charge amount measurement unit 140, and an ionizer 150.

[0020] Although not shown, these components are supported by a drive mechanism for driving (moving) components such as guides and motors, a support member for fixing the position, and the like.

[0021] Further, these components, or the drive mechanism for driving these components, are communicably connected to the computer 90 provided in the component crimping device 100 by wireless or a control line or the like, and execute a predetermined operation by being controlled by the computer 90.

[0022] The computer 90 controls each component provided in the component crimping device 100. The computer 90 is, for example, a computer realized by a communication interface for communicating with each component provided in the component crimping device 100, a non-volatile memory storing a program, a volatile memory which is a temporary storage area for executing the program, an input / output port for transmitting and receiving signals, a processor for executing the program, and the like.

[0023] The sheet holding unit 20 is a reel for accommodating the sheet 400 and supplying the accommodated sheet 400. The sheet 400 is wound up by the rotation of the feed roller 21 and supplied below the crimping head 50.

[0024] Note that the supply of the sheet 400 also means that the position of the sheet 400 located below the crimping head 50 changes. For example, the position of the sheet 400 is moved each time the component 300 is crimped to the substrate 200 by the crimping head 50. That is, the sheet 400 is supplied each time the component 300 is crimped to the substrate 200 by the crimping head 50.

[0025] The sheet holding unit 20 is a support member for supporting the sheet 400. In the present embodiment, in the sheet holding unit 20, the sheet 400 is held in a state of being wound in a roll shape (wound state). The sheet 400 is supplied below the crimping head 50 by being pulled out by the feed roller 21.

[0026] Note that the sheet 400 does not have to be held by the sheet holding unit 20 in a state of being wound in a roll shape, and may be held, for example, in a state of being folded and stacked on the sheet holding unit 20.

[0027] The feed roller 21 is a drive mechanism that withdraws the sheet 400 held by the sheet holding portion 20 by rotating and supplies the sheet 400 below the crimping head 50 from the sheet holding portion 20.

[0028] The crimping head 50 is a head that crimps the component 300 to the substrate 200. For example, the crimping head 50 is attached to the guide 52, and the motor 51 is driven by the computer 90 to move up and down, thereby pressing the component 300 through the sheet 400 to crimp the component 300 to the substrate 200.

[0029] The stage 70 is a base on which the substrate 200 on which the components are arranged is placed. Specifically, the stage 70 holds the substrate 200 in a state where the edge of the substrate 200 does not overlap in a top view (that is, a state where the end of the substrate 200 protrudes). The stage 70 is, for example, a three-axis stage that can be controlled by the computer 90 and moved in the XYZ directions.

[0030] The backup stage 80 is a base that supports the edge of the substrate 200 placed on the stage 70. The backup stage 80 is, for example, a one-axis stage that can be controlled by the computer 90 and moved in the Z direction.

[0031] The charge measurement unit 140 is a sensor that measures the charge amount of the sheet 400. The charge measurement unit 140 measures, for example, the charge amount of the sheet 400 drawn out from the sheet holding portion 20. In the present embodiment, the charge measurement unit 140 measures the charge amount at a position after being drawn out from the sheet holding portion 20 and on the sheet holding portion 20 side rather than at a position pressed by the crimping head 50.

[0032] Note that the charge measurement unit 140 may measure the charge amount of the sheet 400 held by the sheet holding portion 20, or may measure a position on the side opposite to the sheet holding portion 20 with respect to the position pressed by the crimping head 50.

[0033] Further, the charge measurement unit 140 only needs to be able to measure the charge amount of the sheet 400, and it may be a contact-type sensor or a non-contact-type sensor. In the present embodiment, as the charge measurement unit 140, a non-contact-type sensor that can measure the charge amount of the sheet 400 in a non-contact state with the sheet 400 is adopted.

[0034] The ionizer 150 is a device that reduces the charge amount of the sheet 400 by ejecting ionized gas. The ionizer 150 generates ions by generating, for example, corona discharge, and ejects the gas containing the generated ions toward the sheet 400. The ionizer 150 ejects gas, for example, toward the position pressed by the crimping head 50 on the sheet 400. For example, the ionizer 150 is disposed below the sheet 400 and ejects gas toward the lower surface of the position facing the upper surface pressed by the crimping head 50 on the sheet 400.

[0035] Subsequently, the characteristic functional configuration of the component crimping device 100 having the above hardware configuration will be described.

[0036] FIG. 2 is a block diagram showing the functional configuration of the component crimping device 100 according to the embodiment.

[0037] The component crimping device 100 includes a substrate support unit 110, a sheet supply mechanism 120, a crimping tool 130, a charge measurement unit 140, an ionizer 150, a control unit 160, and a storage unit 170.

[0038] The substrate support unit 110 is a base that supports the substrate 200. Specifically, the substrate support unit 110 supports the substrate 200 on which the component 300 is disposed. The substrate support unit 110 is realized by, for example, a stage 70 and a backup stage 80.

[0039] The sheet supply mechanism 120 is a mechanism that supplies a sheet 400 between a crimping tool 130 and a component 300 disposed on a substrate 200 placed on the substrate support portion 110. Specifically, when the substrate 200 on which the component 300 is disposed is located at the crimping position (for example, the position of the substrate 200 shown in FIG. 1, where the lower part of the edge of the substrate 200 is supported by the backup stage 80), the sheet supply mechanism 120 supplies the sheet 400 below the crimping head 50 provided in the crimping tool 130 and above the component 300 disposed on the substrate 200 placed on the substrate support portion 110. The sheet supply mechanism 120 supplies the sheet 400, for example, by shifting the position of the sheet 400 each time the crimping tool 130 presses the component 300 against the substrate 200 by pressing the component 300 against the substrate 200 together with the sheet 400.

[0040] The sheet 400 is held, for example, in a state of being wound in a roll by the sheet supply mechanism 120 (more specifically, the sheet holding portion 20 provided in the sheet supply mechanism 120). The sheet supply mechanism 120 (more specifically, the feed roller 21 provided in the sheet supply mechanism 120) supplies the sheet 400 between the crimping tool 130 (more specifically, the crimping head 50 provided in the crimping tool 130) and the component 300, for example, by pulling out the sheet 400 wound and held in a roll by the sheet holding portion 20.

[0041] The sheet supply mechanism 120 is realized, for example, by the sheet holding portion 20, the feed roller 21, and a motor (not shown) that rotates the feed roller 21.

[0042] The crimping tool 130 is a mechanism for crimping the component 300 to the substrate 200 supported by the substrate support portion 110. Specifically, the crimping tool 130 crimps the component 300 to the substrate 200 by pressing the component 300 against the substrate 200 together with the sheet 400 supplied by the sheet supply mechanism 120. The crimping tool 130 is realized, for example, by the crimping head 50, the motor 51, and the guide 52.

[0043] As described above, the charge measurement unit 140 is a sensor that measures the charge amount of the sheet 400.

[0044] As described above, the ionizer 150 is a device for reducing the charge amount of the sheet 400 by ejecting ionized gas.

[0045] The control unit 160 is a processing unit that controls the operations and operation timings of each component included in the component crimping device 100, such as the substrate support unit 110, the sheet supply mechanism 120, the crimping tool 130, the charge measurement unit 140, and the ionizer 150. The control unit 160 controls the supply of the sheet 400 by the sheet supply mechanism 120 based on the charge amount of the sheet 400 measured by the charge measurement unit 140.

[0046] For example, the control unit 160 controls the supply of the sheet 400 by the sheet supply mechanism 120 by controlling the pulling speed when the sheet supply mechanism 120 pulls out the sheet 400 held by the sheet holding unit 20.

[0047] FIG. 3 is a diagram showing a first example of the pulling speed of the sheet 400 of the sheet supply mechanism 120 included in the component crimping device 100 according to the embodiment. In the graph shown in FIG. 3, the horizontal axis represents time (time), and the vertical axis represents the pulling speed (sheet speed) of the sheet 400.

[0048] First, the control unit 160, for example, controls the sheet supply mechanism 120 to supply the sheet 400 at a first speed for a predetermined time as shown by the dashed-dotted line in FIG. 3, and repeats stopping the supply of the sheet 400 for a predetermined time. While the control unit 160 stops the supply of the sheet 400 to the sheet supply mechanism 120, it controls the crimping tool 130 to crimp the component 300 to the substrate 200.

[0049] Here, for example, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 causes the drawing speed of the sheet 400 of the sheet supply mechanism 120 to change from the state shown by the dashed line in FIG. 3 to the state shown by the solid line in FIG. 3. Specifically, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 changes the drawing speed from the first speed to the second speed, which is a speed lower than the first speed. Further, the control unit 160 lengthens the drawing time in order to move the sheet 400 the same distance as when it was being drawn at the first speed as the drawing speed changes from the first speed to the second speed.

[0050] Note that the predetermined threshold value may be arbitrarily determined in advance and is not particularly limited. Information indicating the predetermined threshold value may be stored in advance in the storage unit 170.

[0051] Also, the time for which the sheet supply mechanism 120 continues to supply the sheet 400 and the time for which the supply of the sheet 400 continues to be stopped may be arbitrarily determined in advance and are not particularly limited. These times may be the same or different. Information indicating these times may be stored in advance in the storage unit 170.

[0052] Also, the time for which the supply of the sheet 400 continues to be stopped does not have to be determined in advance at the start of the stop. For example, the control unit 160 may cancel the stop when the crimping by the crimping tool 130 performed while the supply of the sheet 400 is stopped is completed.

[0053] Further, the control unit 160 may loosen the sheet 400 between when the supply of the sheet 400 is stopped by controlling the sheet supply mechanism 120 and when the crimping by the crimping tool 130 is performed. By loosening the sheet 400, it is possible to suppress the crimping operation by the crimping tool 130 from being inhibited by the sheet 400.

[0054] Also, the first speed and the second speed may be arbitrarily determined in advance and are not particularly limited. Information indicating these speeds may be stored in advance in the storage unit 170.

[0055] Alternatively, the control unit 160 controls the supply of the sheet 400 by the sheet supply mechanism 120, for example, by controlling the time (predetermined time) during which the sheet supply mechanism 120 stops the process of pulling out the sheet 400 held by the sheet holding unit 20.

[0056] FIG. 4 is a diagram showing a second example of the pulling speed of the sheet 400 of the sheet supply mechanism 120 provided in the component crimping device 100 according to the embodiment. In the graph shown in FIG. 4, the horizontal axis represents time (time), and the vertical axis represents the pulling speed (sheet speed) of the sheet 400.

[0057] First, the control unit 160 repeats, for example, controlling the sheet supply mechanism 120 to supply the sheet 400 for a predetermined time as shown by the dashed line in FIG. 4 and then stopping the supply of the sheet 400 for the first time.

[0058] Here, for example, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 changes the stop time of the pulling out of the sheet 400 by the sheet supply mechanism 120 from the state shown by the dashed line in FIG. 4 to the state shown by the solid line in FIG. 4. Specifically, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 changes the time for stopping the pulling out from the first time to the second time, which is a time longer than the first time.

[0059] In this way, the control unit 160 determines a predetermined time based on, for example, the charge amount of the sheet 400 measured by the charge amount measurement unit 140, and controls the supply of the sheet 400 by the sheet supply mechanism 120 so that after the sheet 400 is supplied between the crimping tool 130 and the component 300, the supply of the sheet 400 is stopped for the predetermined time.

[0060] Incidentally, the predetermined time may be arbitrarily determined in advance and is not particularly limited. Information indicating the predetermined time may be stored in the storage unit 170 in advance. Specifically, the first time and the second time may be arbitrarily determined in advance and are not particularly limited. Information indicating these times may be stored in the storage unit 170 in advance.

[0061] The control unit 160 causes the crimping tool 130 to press the component 300 against the substrate 200 together with the sheet 400 supplied by the sheet supply mechanism 120 controlled as described above, thereby crimping the component 300 to the substrate 200.

[0062] Also, for example, the control unit 160 changes the air volume of the gas ejected from the ionizer 150 based on the charge amount of the sheet 400 measured by the charge amount measurement unit 140.

[0063] FIG. 5 is a diagram showing a first example of the air volume of the gas ejected from the ionizer 150 provided in the component crimping apparatus 100 according to the embodiment. Note that the horizontal axis of the graph shown in FIG. 5 indicates time (time), and the vertical axis indicates the air volume of the gas ejected from the ionizer 150 (ionizer air volume).

[0064] First, the control unit 160 causes the ionizer 150 to eject the gas at the first air volume as shown by the dashed line in FIG. 5, for example, by controlling the ionizer 150.

[0065] Here, for example, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 changes the air volume of the gas ejected from the ionizer 150 from the state shown by the dashed line in FIG. 5 to the state shown by the solid line in FIG. 5. Specifically, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 changes the air volume of the gas from the first air volume to the second air volume, which is an air volume greater than the first air volume.

[0066] Note that the first air volume and the second air volume may be arbitrarily determined in advance and are not particularly limited. Information indicating these air volumes may be stored in the storage unit 170 in advance.

[0067] Note that for the ionizer 150, for example, the position where the gas is sprayed is fixed at a specific position (for example, the position pressed by the crimping tool 130) on the sheet 400. Therefore, in order to prevent the ionizer 150 from spraying the gas onto the sheet 400 unnecessarily, for example, in a state where the supply of the sheet 400 is stopped (in other words, in a state where crimping is being performed by the crimping tool 130), the air volume may be reduced.

[0068] FIG. 6 is a diagram showing a second example of the air volume of the gas ejected from the ionizer 150 provided in the component crimping device 100 according to the embodiment. Note that the horizontal axis of the graph shown in FIG. 6 indicates time (time), and the vertical axis indicates the air volume of the gas ejected from the ionizer 150 (ionizer air volume).

[0069] First, for example, by controlling the ionizer 150, the control unit 160 causes the gas to be ejected at the fifth air volume when the crimping tool 130 is crimping, as shown by the dashed-dotted line in FIG. 6, and causes the gas to be ejected at the fourth air volume when the crimping tool 130 is not crimping.

[0070] Here, for example, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 changes the air volume of the gas ejected from the ionizer 150 from the state shown by the dashed-dotted line in FIG. 6 to the state shown by the solid line in FIG. 6. Specifically, when the charge amount of the sheet 400 measured by the charge amount measurement unit 140 exceeds a predetermined threshold value, the control unit 160 changes the air volume of the gas ejected when the crimping tool 130 is not crimping from the fourth air volume to the third air volume, which is an air volume greater than the fourth air volume.

[0071] Note that, for example, the fifth air volume is less than the third air volume and the fourth air volume.

[0072] Also, the third air volume, the fourth air volume, and the fifth air volume may be arbitrarily determined in advance and are not particularly limited. Information indicating these air volumes may be stored in the storage unit 170 in advance.

[0073] As described above, the control unit 160 controls, for example, the sheet supply mechanism 120 and the ionizer 150 based on the charge amount of the sheet 400 measured by the charge amount measurement unit 140.

[0074] Note that the processing by the control unit 160 based on the charge amount of the sheet 400 may be changed according to a plurality of threshold conditions, such as whether it exceeds a first threshold value and whether it exceeds a second threshold value having a different value from the first threshold value, rather than whether it exceeds a predetermined threshold value.

[0075] Further, for example, information indicating the correspondence between the charge amount of the sheet 400 and the pulling speed of the sheet 400 is stored in advance in the storage unit 170, and the control unit 160 may determine the pulling speed of the sheet 400 based on the measurement result of the charge amount of the sheet 400 by the charge amount measurement unit 140 and the information indicating the correspondence.

[0076] Alternatively, for example, information indicating the correspondence between the charge amount of the sheet 400 and the stop time of the pulling of the sheet 400 is stored in advance in the storage unit 170, and the control unit 160 may determine the stop time (predetermined time) of the pulling of the sheet 400 based on the measurement result of the charge amount of the sheet 400 by the charge amount measurement unit 140 and the information indicating the correspondence.

[0077] Alternatively, for example, information indicating the correspondence between the charge amount of the sheet 400 and the air volume of the gas is stored in advance in the storage unit 170, and the control unit 160 may determine the air volume of the gas based on the measurement result of the charge amount of the sheet 400 by the charge amount measurement unit 140 and the information indicating the correspondence.

[0078] Further, the pulling speed of the sheet 400 when the sheet supply mechanism 120 is pulling out the sheet 400 and the air volume of the gas when the ionizer 150 is ejecting the gas may be constant or may not be constant.

[0079] Also, the thresholds used for each process by the control unit 160 based on the charge amount of the sheet 400 may be the same or may be different.

[0080] The control unit 160 is realized by, for example, a processor such as a CPU (Central Processing Unit) included in the computer 90, a control program stored in a memory or the like included in the computer 90 and executed by the processor, and a communication interface or the like for communicating with the substrate support unit 110, the sheet supply mechanism 120, the crimping tool 130, and the like.

[0081] The storage unit 170 is a storage device that stores information indicating types such as the sizes of the substrate 200, the component 300, and the sheet 400, the crimping position, the crimping direction, the operations of the respective components, the timing of the operations, the timing of transferring the substrate 200 to a component crimping device or the like located downstream of the component crimping device 100, control programs executed by the control unit 160, and the like. The storage unit 170 is realized by, for example, a flash memory, an HDD (Hard Disk Drive), or the like.

[0082] [Processing Procedure] Subsequently, the processing procedure of the component crimping device 100 according to the embodiment will be described in detail.

[0083] FIG. 7 is a flowchart showing the processing procedure of the component crimping device 100 according to the embodiment.

[0084] First, the control unit 160 causes the stage 70 to support the substrate 200 on which the component 300 is disposed (S101). For example, the control unit 160 controls a substrate transfer unit (not shown) that transfers the substrate 200 to hold the substrate 200 on the stage 70. At this time, the stage 70 is at a position spaced apart from the backup stage 80 with respect to the position shown in FIG. 1. Therefore, the charge measurement unit 140 can measure the charge amount of the sheet 400 without being blocked by the stage 70 and the substrate 200 held on the stage 70.

[0085] Next, the control unit 160 controls the air volume of the gas ejected from the ionizer 150 based on the charge amount of the sheet 400 measured by the charge amount measurement unit 140 (S102). Specifically, the control unit 160 determines the air volume of the gas ejected from the ionizer 150 based on the charge amount of the sheet 400 measured by the charge amount measurement unit 140, and controls the ionizer 150 to eject the gas at the determined air volume.

[0086] Note that when there is no charge amount of the sheet 400 measured by the charge amount measurement unit 140, such as immediately after the component crimping device 100 is started, the control unit 160 may control the air volume of the gas ejected from the ionizer 150 based on the air volume information indicating a predetermined air volume pre-stored in the storage unit 170. Further, when the component crimping device 100 stops, for example, the control unit 160 may store the charge amount information indicating the charge amount of the sheet 400 last measured by the charge amount measurement unit 140 in the storage unit 170. In this case, for example, the control unit 160 may control the air volume of the gas ejected from the ionizer 150 based on the charge amount information immediately after the component crimping device 100 is started.

[0087] Next, the control unit 160 controls the supply of the sheet 400 based on the charge amount of the sheet measured by the charge amount measurement unit 140 (S103). For example, the control unit 160 controls the supply speed of the sheet 400 by the feed roller 21 based on the charge amount of the sheet 400 measured by the charge amount measurement unit 140. Alternatively, for example, the control unit 160 determines the timing of supplying the sheet 400 (more specifically, a predetermined time that is the stop time of the supply of the sheet 400) based on the charge amount of the sheet 400 measured by the charge amount measurement unit 140, and rotates the feed roller 21 at the determined timing to move the sheet 400 held by the sheet holding unit 20.

[0088] Incidentally, when there is no charge amount of the sheet 400 measured by the charge amount measurement unit 140, for example, immediately after the component crimping device 100 is activated, the control unit 160 may control the supply of the sheet 400 based on sheet supply information indicating a predetermined sheet supply speed or sheet supply timing stored in advance in the storage unit 170. Further, when the component crimping device 100 is stopped, for example, the control unit 160 may cause the storage unit 170 to store charge amount information indicating the charge amount of the sheet 400 last measured by the charge amount measurement unit 140. In this case, for example, the control unit 160 may control the supply of the sheet 400 based on the charge amount information immediately after the component crimping device 100 is activated.

[0089] Next, the charge amount measurement unit 140 measures the charge amount of the sheet 400 (S104). The control unit 160 acquires information indicating the charge amount measured by the charge amount measurement unit 140.

[0090] Next, the control unit 160 compares the charge amount indicated by the information measured by the charge amount measurement unit 140 with a reference value. Specifically, the control unit 160 determines whether the charge amount of the sheet 400 measured by the charge amount measurement unit 140 is less than a predetermined reference value (S105).

[0091] Incidentally, the information indicating the reference value may be stored in advance in the storage unit 170, for example. Also, although it is less than the reference value here, it may be less than or equal to the reference value.

[0092] When the charge amount is less than the reference value (Yes in step S105), the control unit 160 controls the substrate support unit 110 and the crimping tool 130 to press the component 300 against the substrate 200 together with the sheet 400 supplied by the sheet supply mechanism 120, thereby crimping the component 300 to the substrate 200 (S106). Specifically, the control unit 160 controls the stage 70 to move the substrate 200 so that the edge of the substrate 200 is placed on the backup stage 80, that is, so that the substrate 200 is positioned below the crimping tool 130 (more specifically, the crimping head 50). Then, by controlling the sheet supply mechanism 120 to stop the supply of the sheet 400, and with the supply of the sheet 400 stopped, the crimping head 50 is lowered to press the component 300 through the sheet 400, thereby crimping the component 300 to the substrate 200.

[0093] On the other hand, when the charge amount is greater than or equal to the reference value (No in S105), the control unit 160 measures the charge amount of the sheet 400 again (S104). When the answer in step S105 is No, step S106 is not executed, and the state where the gas from the ionizer 150 is ejected onto the sheet 400 is maintained. Therefore, the crimping of the component 300 to the substrate 200 (S106) is not performed until the charge amount drops below the reference value.

[0094] After step S106, the substrate 200 with the component 300 crimped is carried out from the stage 70, and the process returns to step S101 again, and the flow shown in FIG. 7 is repeatedly executed.

[0095] Note that the order in which steps S102 and S103 are performed may be reversed.

[0096] [Effects, etc.] As described above, the component crimping device 100 according to the embodiment includes a substrate support portion 110 that supports the substrate 200, a crimping tool 130 that crimps the component 300 onto the substrate 200 supported by the substrate support portion 110, a sheet supply mechanism 120 that supplies the sheet 400 between the crimping tool 130 (more specifically, the crimping head 50) and the component 300, a charge amount measurement portion 140 that measures the charge amount of the sheet 400, and a control portion 160 that controls the sheet supply mechanism 120 and the crimping tool 130. The control portion 160 controls the supply of the sheet 400 by the sheet supply mechanism 120 based on the charge amount of the sheet 400 measured by the charge amount measurement portion 140, and causes the crimping tool 130 to press the component 300 onto the substrate 200 together with the sheet 400 supplied by the sheet supply mechanism 120, thereby crimping the component 300 onto the substrate 200.

[0097] According to this, for example, when the charge amount of the sheet 400 is large, the control portion 160 can make it difficult to charge the sheet 400, that is, make it difficult to generate static electricity in the sheet 400 or reduce the charge amount of the sheet 400, by, for example, slowing down the supply speed of the sheet 400 by the sheet supply mechanism 120 or increasing the air volume of the gas ejected by the ionizer 150. Therefore, the component crimping device 100 can suppress damage to the substrate 200 caused by static electricity.

[0098] Also, for example, the sheet 400 is held by the sheet supply mechanism 120 in a rolled state. In this case, for example, the sheet supply mechanism 120 supplies the sheet 400 between the crimping tool 130 and the component 300 by pulling out the sheet 400 wound in a roll. Also, in this case, the control portion 160 controls the supply of the sheet 400 by the sheet supply mechanism 120 by, for example, controlling the pulling speed when the sheet supply mechanism 120 pulls out the sheet 400.

[0099] By holding the sheet 400 in a roll shape, it becomes easier to accommodate it in the sheet supply mechanism 120 (more specifically, the sheet holding unit 20), and it can also be easily taken out (pulled out). However, when pulling out the sheet 400 held in a roll shape, the sheet 400 is likely to become charged. Here, since the component crimping device 100 can control the pulling speed of the sheet 400 based on the charge amount of the sheet 400, it is possible to make it difficult for the sheet 400 to become charged. Therefore, the component crimping device 100 is particularly effective in a configuration where the sheet 400 held in a roll shape is pulled out and supplied.

[0100] Also, for example, the control unit 160 determines a predetermined time based on the charge amount of the sheet 400 measured by the charge amount measurement unit 140, and controls the supply of the sheet 400 by the sheet supply mechanism 120 so that after supplying the sheet 400 between the crimping tool 130 and the component 300 to the sheet supply mechanism 120, the supply of the sheet 400 is stopped for a predetermined time.

[0101] The charge amount of the sheet 400 is reduced by the passage of time or gas ejected from the ionizer 150 or the like. Therefore, the control unit 160 determines a predetermined time, which is the time to stop the sheet 400, based on the charge amount of the sheet 400. According to this, the charge amount of the sheet 400 can be appropriately reduced.

[0102] Also, for example, it further includes an ionizer 150 that reduces the charge amount of the sheet 400 by ejecting ionized gas. In this case, the control unit 160 changes the air volume of the gas ejected from the ionizer 150 based on, for example, the charge amount of the sheet 400 measured by the charge amount measurement unit 140.

[0103] According to this, it is possible to suppress unnecessary ejection of gas from the ionizer 150 and appropriately reduce the charge amount of the sheet 400.

[0104] Further, the component crimping method according to the embodiment includes a substrate support step (S101) of supporting the substrate 200 by the substrate support portion 110, a sheet supply step (S103) of supplying the sheet 400 between the crimping tool 130 and the component 300, and a crimping step (S106) of crimping the component 300 to the substrate 200 supported by the substrate support portion 110 by pressing the component together with the sheet 400 supplied in the sheet supply step against the substrate 200 by the crimping tool 130, and a charge amount measurement step (S105) of measuring the charge amount of the sheet 400. In the sheet supply step, the supply of the sheet is controlled based on the charge amount of the sheet 400 measured in the charge amount measurement step.

[0105] According to this, the same effects as those of the component crimping device 100 are achieved.
