[Figure 8] Figure 8 is a diagram illustrating a third example of the time change in the state of the component crimping device according to the embodiment. [Modes for carrying out the invention]

[0011] (Background leading to the present invention) As described above, conventional component crimping devices use a cylinder to press components onto a circuit board. This type of component crimping device includes, for example, a cylinder such as an air cylinder that generates the pressing force of the crimping head, and a motor such as a servo motor that controls the height of the crimping head by raising and lowering it.

[0012] Thus, in a component crimping device that includes a cylinder for pressurizing the crimping head and a servo motor for controlling the height of the crimping head, if, for example, the electromagnetic valve for supplying compressed air to the cylinder malfunctions and the predetermined air pressure is not supplied to the cylinder, the necessary pressure cannot be obtained on the component, which may result in mounting defects. Therefore, in conventional component crimping devices, it is necessary to stop production to prevent the production of defective or other products of reduced quality.

[0013] The inventors of this application have discovered a parts crimping device that can continue production without degrading quality even if there is a malfunction in the pressure adjustment section that adjusts the amount of air supplied to the cylinder.

[0014] Embodiments of the present invention will be described below with reference to the drawings. The embodiments described below are all general or specific examples.

[0016] Furthermore, in this specification and the drawings, the X, Y, and Z axes represent the three axes of a three-dimensional Cartesian coordinate system. In the following embodiments, the Z-axis direction is defined as the vertical direction, and the positive direction of the Z-axis is defined as upward.

[0017] In addition, in this specification, the terms "upper" and "lower" do not refer to the upward (vertically upward) and downward (vertically downward) directions in absolute spatial recognition, but are used as terms defined by relative positional relationships. Further, the terms "upper" and "lower" are applicable not only when two components are arranged at intervals with another component existing between the two components, but also when the two components are arranged in close contact with each other and the two components are in contact with each other.

[0018] (Embodiment) [Configuration] First, the configuration of the component crimping device 200 will be described.

[0019] FIG. 1 is a schematic diagram showing the configuration of the component crimping device 200 according to the embodiment.

[0020] The component crimping device 200 is a device for crimping (i.e., mounting) the component 160 onto the substrate 150. The production system including the component crimping device 200 is a system for producing display panels such as liquid crystal displays, organic EL (Electro Luminescence) displays, and micro LED (Light Emitting Diode) displays.

[0021] Examples of the substrate 150 include display panels using a glass substrate or the like.

[0022] Examples of the component 160 include flexible components such as TCP (Tape Carrier Package) and FPC (Flexible Printed Circuits), and IC (Integrated Circuit) chips.

[0023] The production system is composed of, for example, an ACF (Anisotropic Conductive Film) pasting device, a temporary crimping (component placement) device, the component crimping device 200, and a transfer device.

[0024] The ACF application device is a device for applying ACF tape to electrode terminals provided on the peripheral edge of a substrate 150, such as a glass plate, which has electrode terminals.

[0025] Here, ACF tape refers to a tape-shaped anisotropic conductive film, made from a material that mixes a thermosetting resin with fine conductive metal particles. When ACF tape is pressed under conditions appropriate to the properties of the ACF tape, such as type and size, it maintains conductivity between the terminals positioned above and below the ACF tape, bonds together, and hardens.

[0026] The temporary crimping device is a device that attaches (positions) component 160 to the terminals of electrodes on the peripheral edge of the substrate 150 to which ACF tape has been attached.

[0027] The transport device is a device that transports the substrate 150 between the ACF attachment device, the temporary crimping device, and the component crimping device 200.

[0028] The component crimping device 200 is a so-called standard crimping device that presses the component 160 and the substrate 150 to which the component 160 is attached, under predetermined crimping conditions, via ACF tape attached to the periphery of the substrate 150, thereby crimping the substrate 150 and the component 160. As a result, the ACF tape hardens and electrical conductivity is established between the electrode terminals of the substrate 150 and the electrode terminals of the component 160.

[0029] Here, the crimping conditions refer to the conditions under which the component 160 is pressed against the substrate 150. The crimping conditions include, for example, the time for which the component 160 is pressed against the substrate 150, the temperature at which the pressing occurs, and / or the pressure at which the pressing occurs. For example, the pressing conditions include the flow rate of air supplied to the cylinder 205 and / or the pressure (atmospheric pressure) inside the cylinder 205, that is, the control amount of the solenoid valve 340, and / or the rotation amount of the motor 214.

[0030] The component crimping device 200 is specifically a device for crimping a component 160 to a substrate 150 supported by a support stage 131. In this embodiment, the component crimping device 200 crimps the component 160 to the substrate 150 by pressing the substrate 150, on which the lower end of the substrate 150 is supported by a backup section 201a and the component 160 is placed above the said end, from above with a crimping head 203. The component crimping device 200 comprises a base 201, a backup section 201a, a support column 202, a crimping head 203, a cylinder 205, a stopper 211, an air source 300, a pressure adjustment section 310, a measuring section 320, piping 330, a solenoid valve 340, a motor 214, a support body 220, a control device 230, and a notification section 240.

[0031] The base 201 is a platform for supporting the cylinder 205 (more specifically, the main body 206) and the motor 214, etc. The backup unit 201a and the support column 202 are installed on the base 201.

[0032] The backup section 201a is a lower support section that supports the substrate 150. Specifically, the backup section 201a is a backup stage that supports the peripheral edge of the substrate 150 to which the components 160 are bonded from below, and provides support when the components 160 are pressed against the substrate 150.

[0033] The support column 202 is a columnar member erected on the base 201. The support column 202 is equipped with a ball screw 218 and a movable guide 204.

[0034] The ball screw 218 is a columnar member that is screwed into the support 220 and has a screw groove that supports the support 220 so that it can move in the extending direction of the ball screw 218.

[0035] The movement guide 204 is a guide that restricts the movement of the crimping head 203 relative to the part 160 in a direction along the support column 202.

[0036] The cylinder 205 is mounted on the support column 202 and is a component that generates a pressing force for pressing the substrate 150 and the component 160. Specifically, the cylinder 205 applies a pressing force (a predetermined pressing force) to the crimping head 203 when the crimping head 203 presses the component 160 against the substrate 150. In this embodiment, the cylinder 205 is an air cylinder that generates the pressing force by air supplied from a pressure adjustment unit 310 which has a supply unit for supplying air such as a pump. The cylinder 205 comprises a main body 206, a piston 207, and a piston rod 208.

[0037] The main body 206 is a cylinder tube fixedly attached to the support column 202. Specifically, the main body 206 is fixedly positioned on the support column 202 so that its relative position to the support column 202 does not change. The main body 206 is a hollow cylinder through which a fluid (e.g., air), which serves as a pressure transmission medium, flows in and out.

[0038] The fluid that acts as the pressure transmission medium may be either a compressible fluid such as a gas or an incompressible fluid such as a liquid. In this embodiment, air is supplied to the cylinder 205, but other gases may also be supplied.

[0039] The piston 207 is a disc-shaped part that reciprocates inside the main body 206. Pressure is applied to the piston 207 by air to press the substrate 150 and the component 160 together. A ring member 207a is attached to the outer surface of the piston 207 that contacts the main body 206 to improve airtightness and ensure smooth movement.

[0040] The piston rod 208 is a columnar member connected to the piston 207 and reciprocating in conjunction with the reciprocating motion of the piston 207. The piston rod 208 is provided to be movable along the support column 202. Specifically, the piston rod 208 is a columnar member extending in a direction parallel to the extending direction of the support column 202, and is arranged to be movable (up and down) in a direction parallel to the extending direction of the support column 202. In addition, the piston rod 208 extends on both sides of the piston 207 in the sliding direction of the piston 207.

[0041] The crimping head 203 is a head for pressing the component 160 onto the substrate 150. Specifically, the crimping head 203 is attached to one end of the piston rod 208 (the lower end in this embodiment) and presses the substrate 150, which is supported by the backup section 201a, to crimp the component 160 onto the substrate 150. More specifically, the crimping head 203 is attached to one end (the tip) of the piston rod 208 located in the extending direction of the piston rod 208, on the side where the substrate 150 and the component 160 are placed, and presses the component 160 onto the substrate 150, which is supported by the backup section 201a, to crimp the component 160 onto the substrate 150. The crimping head 203 moves along the extending direction of the support column 202 in conjunction with the movement of the piston rod 208. The crimping head 203 is also equipped with a heater for heat bonding the component 160 to the substrate 150 via ACF tape.

[0042] The stopper 211 is a component provided at the other end (in this embodiment, the upper end) of the piston rod 208, opposite to one end. The stopper 211 is fixed to the piston rod 208.

[0043] The support member 220 is movably mounted along the column 202 and supports the piston rod 208 from one end via the stopper 211. In other words, the support member 220 supports the upper end of the piston rod 208 from the lower end by supporting the lower end of the stopper 211. Specifically, the support member 220 is movably mounted along the column 202 and supports the piston rod 208 from one end via the stopper 211. More specifically, the support member 220 supports the stopper 211 from below from the opposite side of the pressurizing direction by the cylinder 205 (in this embodiment, the negative Z-axis direction), and supports the piston rod 208 via the stopper 211. The support member 220 is screwed into the ball screw 218 and moves in a direction parallel to the extending direction of the column 202 in conjunction with the rotation of the ball screw 218. This movement causes the piston rod 208 and the crimping head 203 provided on the piston rod 208, which are supported by the support 220, to move along the support column 202.

[0044] The air source 300 is a pump that supplies air to the cylinder 205. Specifically, the air source 300 supplies air to the cylinder 205 via the piping 330.

[0045] The piping 330 is a pipe that supplies air, whose pressure has been regulated by the pressure regulating unit 310, to the cylinder 205. Specifically, the piping 330 connects the air source 300 and the cylinder 205 via the pressure regulating unit 310 and the solenoid valve 340, and supplies air from the air source 300 to the cylinder 205. The piping 330 is equipped with the pressure regulating unit 310, the measuring unit 320, and the solenoid valve 340.

[0046] The pressure adjustment unit 310 is connected to an air source 300 that supplies air to generate a pressing force to the cylinder 205, and is a device that adjusts the pressure of the air supplied from the air source 300. Specifically, the pressure adjustment unit 310 controls the pressing force by the cylinder 205 so that the cylinder 205 generates the pressing force necessary to apply a target pressing force (hereinafter also referred to as the target pressing force) to the substrate 150 and the component 160. The pressure adjustment unit 310 is implemented, for example, by a regulator such as an electromagnetic valve that controls the amount of air supplied.

[0047] The measuring unit 320 is a measuring instrument that measures the air pressure or air flow rate inside the piping 330. The measuring unit 320 is, for example, a flow meter installed in the piping 330.

[0048] The measuring unit 320 may, for example, be a pressure gauge installed in the piping 330. Furthermore, the measuring unit 320 may be configured to measure both air pressure and air flow rate, such as by including a flow meter and a pressure gauge.

[0049] The solenoid valve 340 is an electromagnetic valve that switches the supply of air from the air source 300 to the cylinder 205 on and off.

[0050] Motor 214 is a motor that moves the support body 220 along the support column 202. Specifically, motor 214 is a drive source that rotates a ball screw 218 and moves the support body 220, which is screwed into the ball screw 218, along the support column 202. In other words, motor 214 moves the support body 220 in a direction parallel to the extending direction of the piston rod 208. In this embodiment, motor 214 is a servo motor (more specifically, an AC servo motor) equipped with an encoder and a driver.

[0051] The encoder is a detector for detecting the position of the drive shaft of the motor 214. The encoder outputs position information indicating the detected position of the drive shaft to the control device 230 via a driver. Position information includes, for example, information such as the amount of rotation (rotation angle) and rotation speed. The driver is a drive circuit for driving the motor 214 in accordance with commands from the control device 230. The driver outputs information regarding the torque of the motor 214 to the control device 230. For example, the control device 230 controls the rotational operation of the motor 214 based on information such as the torque of the motor 214 detected by the encoder and driver of the motor 214.

[0052] The control device 230 is a control device that issues commands to the driver to control the drive of the motor 214, and controls the pressing force of the cylinder 205 by controlling the pressure adjustment unit 310 and the solenoid valve 340.

[0053] The control device 230 controls the start of movement, the speed of movement, and the position after movement of the support body 220 by controlling the amount of rotation of the motor 214 based on information such as the torque from the motor 214. The control device 230 also obtains information such as the sum of the thicknesses of the substrate 150 and the component 160, and the pressing force applied to the substrate 150 and the component 160 from the storage unit 235, and determines the position where the support body 220 should be placed based on the obtained information.

[0054] Furthermore, the control device 230 supplies air from the air source 300 to the cylinder 205 by controlling the pressure adjustment unit 310 and the solenoid valve 340 based, for example, on the measurement results from the measuring unit 320 and the pressing conditions stored in the storage unit 235.

[0055] The control device 230 is implemented by, for example, an interface to which control lines for controlling the pressure adjustment unit 310, the solenoid valve 340, and the motor 214 are connected, 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.

[0056] The control device 230 includes an acquisition unit 231, a detection unit 232, a control unit 233, an output unit 234, and a storage unit 235.

[0057] The acquisition unit 231 is a processing unit that acquires various types of information used in the processing performed by the control unit 233. For example, the acquisition unit 231 acquires torque information related to the torque of the motor 214 from the motor 214.

[0058] Torque information is, for example, a current value corresponding to the torque generated in motor 214, output from the driver of motor 214.

[0059] Furthermore, for example, the acquisition unit 231 acquires the measurement results from the measurement unit 320. The measurement results are, for example, information indicating the air pressure or air flow rate inside the piping 330.

[0060] The detection unit 232 is a processing unit that detects abnormalities in the cylinder 205 based on the measured values ​​(i.e., the measurement results of the measurement unit 320) measured by the measurement unit 320. Specifically, the detection unit 232 determines whether or not an abnormality has occurred in the cylinder 205 based on the measurement results of the measurement unit 320.

[0061] For example, the detection unit 232 detects a first abnormality based on the measurement value measured by the measurement unit 320.

[0062] The first abnormality is, for example, an abnormality in which the air pressure determined by the measurement result of the measuring unit 320 at a predetermined timing is different from a predetermined pressure target value. The first abnormality is, for example, an abnormality in which the air pressure determined by the measurement result of the measuring unit 320 is higher than a predetermined pressure target value.

[0063] The first abnormality may be, for example, an abnormality in which the air pressure determined by the measurement result of the measuring unit 320 is lower than a predetermined pressure target value. Alternatively, the first abnormality may be, for example, an abnormality in which the air pressure determined by the measurement result of the measuring unit 320 is not within a predetermined range that includes the predetermined pressure target value.

[0064] Furthermore, the predetermined timing is, for example, after a predetermined time has elapsed since the supply of air to the pressurized port of cylinder 205 began. The predetermined timing (i.e., the predetermined time) can be determined arbitrarily and is not particularly limited.

[0065] Furthermore, if the measuring unit 320 is a flow meter that detects the air flow rate, the detection unit 232 may calculate the air pressure based on the air flow rate.

[0066] The control unit 233 is a processing unit that controls the cylinder 205 (more specifically, the pressure adjustment unit 310 and the solenoid valve 340) and the motor 214. Specifically, the control unit 233 controls the crimping head 203 based on the pressing conditions when the crimping head 203 presses the component 160 against the substrate 150, thereby performing the pressing by the crimping head 203. More specifically, the control unit 233 controls the cylinder 205 and the motor 214 to move the support 220 together with the piston rod 208 toward one end of the piston rod 208, causing the crimping head 203 to crimp the component 160 onto the substrate 150 supported by the backup unit 201a. More specifically, the control unit 233 performs a first control by controlling the cylinder 205 to support the piston rod 208 on the support 220 via the stopper 211, thereby generating a predetermined pressing force acting from the piston rod 208 toward one end of the piston rod 208 toward the support 220 via the stopper 211. Then, by controlling the motor 214, it performs a second control to move the support 220 together with the piston rod 208 toward one end of the piston rod 208, thereby pressing the component 160 onto the substrate 150 with the crimping head 203.

[0067] The pressing conditions include, for example, the amount of air supplied to the cylinder 205 (i.e., the air pressure, or in other words, the pressing force generated on the crimping head 203), the timing of the air supply, the control timing of the motor 214, and the torque value of the motor 214 (i.e., the amount of current supplied to the motor 214).

[0068] Figure 2 is a diagram illustrating the operation of the piston rod 208 and support body 220 of the component crimping device 200 according to the embodiment.

[0069] As shown in Figure 2(a), for example, before the component crimping device 200 crimps the component 160 to the substrate 150, the piston rod 208 is positioned such that the stopper 211 located at the other end of the piston rod 208 is not in contact with the support 220. In other words, in this state, the piston rod 208 is not supported by the support 220. For example, the control unit 233 controls the pressure adjustment unit 310 and the solenoid valve 340 to supply air to the depressurization port of the cylinder 205, thereby keeping the piston rod 208 in a state where it is not supported by the support 220.

[0070] Next, as shown in Figure 2(b), when the component crimping device 200 crimps the component 160 onto the substrate 150, the control unit 233 controls the cylinder 205 to move the piston rod 208 downward, performing a first control to bring the stopper 211 located at the other end of the piston rod 208 into contact with the support body 220. As a result, the piston rod 208 is supported by the support body 220. At this time, the pressing force acting from the piston rod 208 toward one end of the piston rod 208 toward the support body 220 is a predetermined pressing force. Also, torque is generated in the motor 214 to maintain the position of the support body 220, which is about to be moved downward by this pressing force.

[0071] Next, as shown in Figure 2(c), the control unit 233 performs a second control to press the component 160 to the substrate 150 by controlling the cylinder 205 to move the piston rod 208 downward and controlling the motor 214 to move the support 220 downward. In other words, the component 160 is pressed against the substrate 150 while a predetermined pressing force is generated toward one end of the piston rod 208. This makes it possible to press the component 160 to the substrate 150 while applying a pressing force from the cylinder 205 (more specifically, the piston rod 208) corresponding to the predetermined pressing force to the substrate 150 and the component 160.

[0072] Next, as shown in Figure 2(d), the control unit 233 controls the cylinder 205 to move the piston rod 208 upward, thereby eliminating the generated pressing force and stopping the crimping.

[0073] Next, the control unit 233 controls the motor 214 to move the support 220 upward, thereby returning the piston rod 208 and the support to the state shown in Figure 2(a).

[0074] Figure 3 is a diagram illustrating the first example of the time change in the state of the component crimping device 200 according to the embodiment. This example is an example in which no abnormality is detected in the component crimping device 200. Specifically, Figure 3(a) is a graph showing the air flow rate, which is an example of the measurement result measured by the measuring unit 320. Figure 3(b) is a graph showing the air pressure, which is another example of the measurement result measured by the measuring unit 320. Figure 3(c) is a graph schematically showing the time change in the downward driving force applied to the piston rod 208. Figure 3(d) is a graph schematically showing the time change in the height of the crimping head 203. Figure 3(e) is a graph schematically showing the time change in the force (pressing force) that the piston rod 208 exerts on the support 220. Figure 3(f) is a graph schematically showing the time change in the height of the support 220. Furthermore, Figure 3(g) is a schematic graph showing the time change in the pressing force applied by the crimping head 203 to the substrate 150 when pressing the component 160 against it.

[0075] As shown in Figures 3(a) and 3(b), when the supply of air to the pressurizing port of the cylinder 205 is started, in other words, when the supply of air (also called supply of air pressure) to the main body 206 is started by the first control to move the piston rod 208 downward, the height of the crimping head 203 decreases without changing the height of the support 220, as shown in Figures 3(d) and 3(f). That is, the piston rod 208 moves downward. Next, as shown in Figure 3(e), the stopper 211 and the support 220 come into contact, and a predetermined pressing force is generated acting on the support 220. Next, as shown in Figure 3(f), the support 220 is moved downward by the second control while the predetermined pressing force has been generated, and the crimping head 203 comes into contact with the part 160, so that a pressing force is generated on the crimping head 203 corresponding to the force with which the piston rod 208 pushes down the support 220, as shown in Figure 3(g), and the part 160 is crimped to the substrate 150. The detection unit 232 determines, for example, whether the cylinder 205 is operating normally based on the airflow rate or air pressure from the time air is supplied to the pressurized port of the cylinder 205 until the support 220 is lowered.

[0076] Here, for example, the control unit 233 changes the pressing conditions when the detection unit 232 detects a first abnormality.

[0077] In this embodiment, the first abnormality is an abnormality in which the air pressure value in the piping 330 falls outside the first permissible range. For example, when the first abnormality is detected by the detection unit 232, the control unit 233 changes at least one of the following, which are included in the pressing conditions: (i) the pressing time when the crimping head 203 presses the component 160 against the substrate 150, and (ii) the set value of the pressing force when the crimping head 203 presses the component 160 against the substrate 150, before performing pressing with the crimping head 203.

[0078] Figure 4 is a diagram illustrating a second example of the time change in the state of the component crimping device 200 according to the embodiment. This example is an example of a case in which an abnormality (specifically, a first abnormality) is detected in the component crimping device 200. Specifically, Figure 4(a) is a graph showing an example of the air pressure measured by the measuring unit 320. Figure 4(b) is a graph schematically showing the time change in the downward driving force applied to the piston rod 208. Figure 4(c) is a graph schematically showing the time change in the height of the crimping head 203. Figure 4(d) is a graph schematically showing the time change in the force (pressing force) that the piston rod 208 applies to the support 220. Figure 4(e) is a graph schematically showing the time change in the height of the support 220. Figure 4(f) is a graph schematically showing the time change in the pressing force that the crimping head 203 applies to pressing the component 160 against the substrate 150.

[0079] As shown in Figure 4(a), when the supply of air to the pressurized port of the cylinder 205 is started, in other words, when the supply of air (also called supply of air pressure) to the main body 206 is started by the first control to move the piston rod 208 downward, the height of the crimping head 203 decreases without changing the height of the support 220, as shown in Figures 4(c) and (e). That is, the piston rod 208 moves downward.

[0080] Here, for example, as shown in Figure 4(a), suppose the air pressure measured by the measuring unit 320 is higher than a predetermined target pressure value. The detection unit 232 determines, for example, based on the measurement result, whether or not the air pressure measured by the measuring unit 320 is higher than the target pressure value. The detection unit 232 determines, for example, that a first abnormality has occurred if the air pressure measured by the measuring unit 320 is higher than the target pressure value. When the detection unit 232 detects a first abnormality, that is, when the detection unit 232 determines that the pressure is higher than the target pressure value, the control unit 233 changes the pressing conditions so that the air pressure becomes the target pressure value. Specifically, in this case, the control unit 233 controls, for example, the pressure adjustment unit 310 so that the air pressure becomes the target pressure value.

[0081] In the example shown in Figure 4, the timing of the change in the pressing conditions when an abnormality is detected is before the support 220 begins to descend, but this is not limited to this. The pressing conditions may be changed while the support 220 is descending, as long as it is before the crimping head 203 and the component 160 come into contact.

[0082] The pressing conditions before the control unit 233 makes the change can be arbitrarily determined in advance and are not particularly limited.

[0083] Furthermore, the pressing time may be changed by modifying the control content of the pressure adjustment unit 310 and / or the solenoid valve 340, or by modifying the control content of the motor 214.

[0084] The output unit 234 is a processing unit that outputs the determination result (determination result information) from the detection unit 232 to the notification unit 240.

[0085] Furthermore, the output unit 234 may output fault information indicating that the cylinder 205 is not functioning properly as a determination result if the detection unit 232 determines that the cylinder 205 is not functioning properly. In this case, for example, the output unit 234 does not need to output the determination result if the detection unit 232 determines that the cylinder 205 is functioning properly.

[0086] The memory unit 235 is a storage device that stores various data necessary for component crimping, such as pressing conditions, the size of the substrate 150, the types of components 160 to be mounted on the substrate 150, mounting positions, mounting directions, the operation of each device, the timing of said operation, and the timing for transporting the substrate 150, as well as control programs executed by the processing unit.

[0087] The memory unit 235 is implemented by memory such as ROM (Read Only Memory) or RAM (Random Access Memory).

[0088] The notification unit 240 is a device that notifies (informs) the user of the determination result made by the detection unit 232.

[0089] For example, the notification unit 240 notifies the occurrence of the first abnormality. For example, when the detection unit 232 detects the first abnormality, the control unit 233 causes the notification unit 240 to notify that the first abnormality has been detected.

[0090] For example, if the detection unit 232 determines that the cylinder 205 is not functioning properly, the notification unit 240 notifies the detection unit 232 of a malfunction indicating that the cylinder 205 is not functioning properly as a result of the determination.

[0091] For example, if the detection unit 232 determines that the cylinder 205 is functioning normally, the notification unit 240 does not need to notify the determination result.

[0092] The notification unit 240 can be any device that can notify the user of the judgment result made by the detection unit 232. For example, it may be a display device such as a display that shows an image indicating the judgment result, or an audio device that outputs a sound indicating the judgment result.

[0093] The input unit 250 is a user interface that accepts user input. The input unit 250 can be implemented, for example, by buttons, a mouse, a keyboard, and / or a touch panel.

[0094] [Processing Procedure] Next, we will explain the processing procedure of the component crimping device 200.

[0095] Figure 5 is a flowchart showing the processing procedure of the component crimping device 200 according to the embodiment.

[0096] First, the control unit 233 adjusts the pressing force applied to the crimping head 203 by controlling the cylinder 205 (S110). Specifically, the control unit 233 causes the piston rod 208 to be supported by the support body 220 via the stopper 211. More specifically, the control unit 233 causes the pressure adjustment unit 310 to supply a predetermined air pressure to the main body 206 so that the piston rod 208 moves downward, thereby causing the lower end of the stopper 211 to be supported by the support body 220, and thus causing the piston rod 208, which is fixed to the stopper 211, to be supported by the support body 220 from below. As a result, the control unit 233 generates a predetermined pressing force acting from the piston rod 208 toward one end of the piston rod 208 toward the support body 220.

[0097] Next, the measuring unit 320 measures the air pressure and air flow rate inside the piping 330 (S120).

[0098] Next, the detection unit 232 determines whether or not a first abnormality has occurred based on the measurement value measured by the measurement unit 320 (S130).

[0099] If the detection unit 232 determines that no first abnormality has occurred (No in S130), that is, if the detection unit 232 does not detect a first abnormality, the control unit 233 controls the motor 214 to move the support 220 together with the piston rod 208 toward one end of the piston rod 208, causing the crimping head 203 to crimp the component 160 to the substrate 150 (S140).

[0100] As a result, the control unit 233 can press the component 160 to the substrate 150 with the crimping head 203 while generating a predetermined pressing force.

[0101] On the other hand, if the detection unit 232 determines that a first abnormality has occurred (Yes in S130), that is, if the detection unit 232 detects a first abnormality, the control unit 233 changes the pressing conditions based on the measured value measured by the measurement unit 320 (S150).

[0102] Next, the control unit 233 causes the crimping head 203 to perform crimping in step S140 based on the changed pressing conditions.

[0103] [Differentiation] <Example 1> The control unit 233 may change the pressing conditions if permitted by the user.

[0104] For example, permission to change the pressing conditions is input to the input unit 250. The acquisition unit 231 acquires information such as permission to change the pressing conditions input in the input unit 250. The control unit 233 changes the pressing conditions after permission to change the pressing conditions has been input to the input unit 250. In this way, for example, when the detection unit 232 detects a first abnormality, the control unit 233 notifies the notification unit 240 that a first abnormality has been detected, and changes the pressing conditions after permission to change the pressing conditions has been input to the input unit 250.

[0105] Figure 6 is a flowchart showing a modified example 1 of the processing procedure of the component crimping device 200 according to the embodiment.

[0106] First, the control unit 233 adjusts the pressing force applied to the crimping head 203 by controlling the cylinder 205 (S110).

[0107] Next, the measuring unit 320 measures the air pressure and air flow rate inside the piping 330 (S120).

[0108] Next, the detection unit 232 determines whether or not a first abnormality has occurred based on the measurement value measured by the measurement unit 320 (S130).

[0109] If the detection unit 232 determines that no first abnormality has occurred (No in S130), that is, if the detection unit 232 does not detect a first abnormality, the control unit 233 controls the motor 214 to move the support 220 together with the piston rod 208 toward one end of the piston rod 208, causing the crimping head 203 to crimp the component 160 to the substrate 150 (S140).

[0110] On the other hand, if the detection unit 232 determines that a first abnormality has occurred (Yes in S130), that is, if the detection unit 232 detects a first abnormality, the control unit 233 will notify the notification unit 240 that a first abnormality has occurred (S160).

[0111] Next, the control unit 233 determines whether permission to change the pressing conditions has been obtained (S170). Specifically, the control unit 233 determines whether permission to change the pressing conditions has been input to the input unit 250.

[0112] If the control unit 233 determines that it has obtained permission to change the pressing conditions (Yes in S170), it changes the pressing conditions based on the measured value measured by the measuring unit 320 (S150).

[0113] Next, the control unit 233 causes the crimping head 203 to perform crimping in step S140 based on the changed pressing conditions.

[0114] On the other hand, if the control unit 233 determines that it has not obtained permission to change the pressing conditions (No in S170), it will terminate the process without performing step S140, that is, without crimping the component 160 to the substrate 150 (i.e., it will stop the crimping).

[0115] Furthermore, the control unit 233 may determine "No" in step S170 if it has not obtained permission to change the pressing conditions even after a predetermined time has elapsed since executing step S160. Also, for example, the control unit 233 may determine "No" in step S170 if it obtains information indicating that permission to change the pressing conditions is not granted.

[0116] Furthermore, when the control unit 233 notifies the notification unit 240 that a first abnormality has been detected, it may also notify the notification unit 240 of the changes in the pressing conditions.

[0117] Furthermore, the input unit 250 may accept input of changes to the pressing conditions. In this case, the control unit 233 may change the pressing conditions in accordance with the changes to the pressing conditions received by the input unit 250.

[0118] <Modification 2> The abnormality detected by the detection unit 232 does not have to be the first abnormality described above. For example, the detection unit 232 may detect a second abnormality that is different from the first abnormality. For example, based on the measurement value measured by the measurement unit 320, the detection unit 232 may detect a second abnormality that is different from the first abnormality, in addition to the first abnormality.

[0119] A second anomaly is, for example, an anomaly of the same type as the first anomaly, but with a different threshold set for it. Specifically, a second anomaly may be an anomaly set based on criteria that are more relaxed than those for the first anomaly.

[0120] The first and second abnormalities are, for example, abnormalities in which the air pressure determined by the measurement result of the measuring unit 320 at a predetermined timing differs from a predetermined pressure target value. The first abnormality is, for example, an abnormality in which the difference between the air pressure determined by the measurement result of the measuring unit 320 and the predetermined pressure target value is greater than or equal to the first threshold. On the other hand, the second abnormality is, for example, an abnormality in which the difference between the air pressure determined by the measurement result of the measuring unit 320 and the predetermined target value is less than the first threshold and greater than or equal to the second threshold. For example, the first threshold may be set as ±10% of the predetermined pressure target value, and the second threshold may be set as ±5% of the predetermined pressure target value.

[0121] For example, the notification unit 240 notifies the occurrence of a second abnormality. For example, when the detection unit 232 detects a second abnormality, the control unit 233 causes the notification unit 240 to notify the notification unit 240 that a second abnormality has been detected.

[0122] Furthermore, if the detection unit 232 detects a second abnormality, the control unit 233 may notify the notification unit 240 that a second abnormality has been detected, and may also perform pressing with the crimping head 203 without changing the pressing conditions.

[0123] Figure 7 is a flowchart showing a modified example 2 of the processing procedure of the component crimping device 200 according to the embodiment.

[0124] First, the control unit 233 adjusts the pressing force applied to the crimping head 203 by controlling the cylinder 205 (S110).

[0125] Next, the measuring unit 320 measures the air pressure and air flow rate inside the piping 330 (S120).

[0126] Next, the detection unit 232 determines whether or not a first abnormality has occurred based on the measurement value measured by the measurement unit 320 (S130).

[0127] If the detection unit 232 determines, based on the measurement value measured by the measurement unit 320, that a first abnormality has not occurred (No in S130), that is, if it does not detect a first abnormality, it determines, based on the measurement value measured by the measurement unit 320, whether a second abnormality has occurred or not (S180).

[0128] If the detection unit 232 determines that no second abnormality has occurred (No in S180), that is, if the detection unit 232 does not detect a second abnormality, the control unit 233 controls the motor 214 to move the support 220 together with the piston rod 208 toward one end of the piston rod 208, causing the crimping head 203 to crimp the component 160 to the substrate 150 (S140).

[0129] On the other hand, if the detection unit 232 determines that a second abnormality has occurred (Yes in S180), that is, if the detection unit 232 detects a second abnormality, the control unit 233 will notify the notification unit 240 that a second abnormality has occurred (S190).

[0130] Next, the control unit 233 causes the crimping head 203 to perform crimping in step S140 based on the pressing conditions.

[0131] If the detection unit 232 determines that a first abnormality has occurred (Yes in S130), that is, if the detection unit 232 detects a first abnormality, the control unit 233 performs the processing from step S160 onwards as described above.

[0132] The notification given in step S160 or step S190 may continue for a predetermined time, or it may continue until, for example, instructions are received from the user via the input unit 250, or it may continue until the component crimping device 200 stops operating. Also, for example, if there is a change in the type of product produced by the component crimping device 200 (for example, if there is a change in the type of circuit board 150 or component 160), the notification may be stopped or continued.

[0133] Furthermore, if the answer to step S130 or step S180 is Yes, that is, if a first or second abnormality is detected, the detection unit 232 may, for example, store the measurement result measured by the measurement unit 320 in the storage unit 235.

[0134] Furthermore, if the answer to step S180 is Yes, the component crimping device 200 does not need to perform step S140. In other words, in this case, the component crimping device 200 may terminate the process without crimping the component 160 to the substrate 150.

[0135] <Variation 3> The types of abnormalities detected by the detection unit 232 are not limited to the first and second abnormalities described above. For example, the detection unit 232 may detect an abnormality of the type described later as the first abnormality.

[0136] The first abnormality may be, for example, an abnormality in which the amount of change per unit time of the air pressure determined by the measurement result of the measuring unit 320 is different from a predetermined amount of change. The first abnormality may also be, for example, an abnormality in which the amount of change determined by the measurement result of the measuring unit 320 is lower than a predetermined amount of change.

[0137] The first abnormality may be, for example, an abnormality in which the amount of change determined by the measurement result of the measurement unit 320 is lower than a predetermined amount of change. Alternatively, the first abnormality may be, for example, an abnormality in which the amount of change determined by the measurement result of the measurement unit 320 is not within a predetermined range that includes the predetermined amount of change.

[0138] In this example, the first abnormality is an abnormality in which the pressure adjustment time from the start to the completion of air pressure adjustment by the pressure adjustment unit 310 falls outside the second allowable range. When the first abnormality is detected by the detection unit 232, the control unit 233 changes the pressing start time, which is included in the pressing conditions, when the crimping head 203 presses the component 160 against the substrate 150, and then performs pressing with the crimping head 203.

[0139] For example, the control unit 233 changes the pressing start time by changing the control content of the motor 214.

[0140] Figure 8 is a diagram illustrating a third example of the time change in the state of the component crimping device 200 according to the embodiment. This example is an example of a case in which an abnormality (specifically, a first abnormality) is detected in the component crimping device 200. Specifically, Figure 8(a) is a graph showing an example of the air pressure measured by the measuring unit 320. Figure 8(b) is a graph schematically showing the time change in the downward driving force applied to the piston rod 208. Figure 8(c) is a graph schematically showing the time change in the height of the crimping head 203. Figure 8(d) is a graph schematically showing the time change in the force (pressing force) that the piston rod 208 exerts on the support 220. Figure 8(e) is a graph schematically showing the time change in the height of the support 220. Figure 8(f) is a graph schematically showing the time change in the pressing force that the crimping head 203 exerts on the component 160 to the substrate 150.

[0141] Furthermore, in each graph shown in Figure 8, the solid line represents data when an abnormality is detected, and the dashed line represents data when no abnormality is detected, i.e., when crimping is performed normally.

[0142] As shown by the dashed line in Figure 8(a), when the supply of air to the pressurized port of the cylinder 205 is started, in other words, when the supply of air (also called supply of air pressure) to the main body 206 is started by the first control to move the piston rod 208 downward, if the component crimping device 200 is functioning correctly, the height of the crimping head 203 will decrease without changing the height of the support 220, as shown by the dashed lines in Figures 8(c) and (e). In other words, the piston rod 208 moves downward.

[0143] Here, suppose the change in air pressure per unit time measured by the measuring unit 320 is lower than a predetermined amount of change. The detection unit 232 determines, for example, based on the measurement result, whether the change in air pressure measured by the measuring unit 320 is lower than a predetermined amount of change. The detection unit 232 determines, for example, that a first abnormality has occurred if the change in air pressure measured by the measuring unit 320 is lower than a predetermined amount of change. When the detection unit 232 detects a first abnormality, that is, when the detection unit 232 determines that the change is lower than a predetermined amount, the control unit 233 stops the process of lowering the support 220 until the air pressure reaches the pressure target value.

[0144] For example, suppose that a predetermined change in air pressure is as shown by the dashed line in Figure 8(a), and the measurement unit 320 measures a change in air pressure as shown by the solid line in Figure 8(a). In this case, for example, the detection unit 232 detects a first abnormality based on the measurement result of the measurement unit 320 and the predetermined change in air pressure. If the detection unit 232 determines that the change is lower than the predetermined amount, the first control unit 233 stops the process of lowering the support 220, for example as shown by the solid line in Figure 8(e)(1), until the air pressure reaches the pressure target value.

[0145] In this way, the control unit 233 changes the pressing conditions to alter the timing of lowering the support 220, thereby causing the crimping head 203 to perform crimping when the air pressure reaches the target pressure value.

[0146] The control unit 233 may also change the pressing conditions to change the speed at which the support 220 is lowered, as shown by the dashed line in (2) of (e) in Figure 8.

[0147] Furthermore, the control unit 233 may change the pressing conditions to delay the timing of lowering the support 220 and increase the speed at which the support 220 is lowered, as shown by the dashed line in (3) of (e) in Figure 8. In other words, the control unit 233 may change the pressing conditions, such as the timing and / or speed at which the support 220 is lowered, based on the measurement results of the measuring unit 320.

[0148] Furthermore, a second abnormality may be detected that is of the same type as the first abnormality shown in this modified example, but with a different threshold value set for that first abnormality. In other words, modified example 2 and modified example 3 may be combined. Thus, the embodiments and the configurations and processing procedures of each modified example may be combined in any way.

[0149] [Effects, etc.] As described above, the component crimping device 200 according to the embodiment includes a crimping head 203 that presses the component 160 onto the substrate 150, a cylinder 205 that applies pressure to the crimping head 203 when the crimping head 203 presses the component 160 onto the substrate 150, a pressure adjustment unit 310 connected to an air source 300 that supplies air to generate pressure to the cylinder 205 and adjusts the pressure of the air supplied from the air source 300, and the air adjusted by the pressure adjustment unit 310 that is supplied to the cylinder 205. The system includes a piping 330, a measuring unit 320 for measuring the air pressure or air flow rate inside the piping 330, a detection unit 232 for detecting a first abnormality based on the measurement value measured by the measuring unit 320, and a control unit 233 for performing pressing by the crimping head 203 by controlling the crimping head 203 based on the pressing conditions when the crimping head 203 presses the component 160 against the substrate 150. The control unit 233 changes the pressing conditions when the detection unit 232 detects a first abnormality.

[0150] In conventional component crimping devices, it is uncertain whether the correct air flow rate or air pressure is supplied to the cylinder 205. Therefore, there is a possibility that the component 160 may be crimped to the substrate 150 with an inappropriate pressing force generated by the crimping head 203 (the pressing force value is inappropriate). As a result, defective products may be produced in conventional component crimping devices 200. Furthermore, in conventional component crimping devices, even if it is discovered that the correct air flow rate or air pressure is not supplied to the cylinder 205 due to some factor, the component crimping device may not be able to produce until, for example, the user performs maintenance on the component crimping device. Therefore, in the component crimping device 200 according to this embodiment, when a first abnormality is detected based on the measurement value measured by the measuring unit 320, that is, when an abnormality related to the air pressure or air flow rate supplied to the cylinder 205 is detected, the pressing conditions are changed (for example, feedforward). For example, if an abnormality is detected in the air pressure or air flow rate supplied to the cylinder 205, the pressing conditions are changed by increasing the pressing force so that the air pressure or air flow rate reaches the predetermined value. As a result, the parts crimping device 200 can produce under substantially the same conditions as when no abnormality is detected, even when an abnormality is detected, that is, when there is a malfunction in the pressure adjustment unit 310. Therefore, the parts crimping device 200 can continue production without degrading quality even when there is a malfunction in the pressure adjustment unit 310.

[0151] Furthermore, for example, the component crimping device 200 further includes a notification unit 240 that notifies the occurrence of a first abnormality and an input unit 250 into which permission to change the pressing conditions is input. When the detection unit 232 detects a first abnormality, the control unit 233 notifies the notification unit 240 that a first abnormality has been detected, and changes the pressing conditions after permission to change the pressing conditions has been input to the input unit 250.

[0152] According to this, the occurrence of an anomaly can be notified to the user. In addition, it prevents the user from unintentionally changing the pressing conditions.

[0153] Furthermore, for example, the detection unit 232 detects a second abnormality different from the first abnormality based on the measurement value measured by the measurement unit 320, and when the detection unit 232 detects the second abnormality, the control unit 233 notifies the notification unit 240 that the second abnormality has been detected, and performs pressing with the crimping head 203 without changing the pressing conditions.

[0154] As described above, the second abnormality may be an abnormality set based on criteria that are more relaxed than those for the first abnormality. In this case, the component crimping device 200 can notify the user of an indication of an abnormality that would result in the production of defective products by setting the air flow rate or air pressure to an abnormal level that would not result in the production of defective products as the second abnormality.

[0155] Furthermore, for example, the first abnormality is an abnormality in which the air pressure value in the piping 330 falls outside the first permissible range. When the first abnormality is detected by the detection unit 232, the control unit 233 changes at least one of the following, which are included in the pressing conditions: (i) the pressing time when the crimping head 203 presses the component 160 against the substrate 150, and (ii) the set value of the pressing force when the crimping head 203 presses the component 160 against the substrate 150, before performing pressing with the crimping head 203.

[0156] If an abnormality occurs in the air pressure value within the piping 330, it is likely that an abnormality will occur in the pressing force. Therefore, the control unit 233 changes the pressing conditions so that the component 160 is properly pressed onto the substrate 150 even if an abnormality occurs in the pressing force. As a result, the component crimping device 200 can continue production even if an abnormality occurs in the pressing force.

[0157] Furthermore, for example, the first abnormality is an abnormality in which the pressure adjustment time from the start to the completion of air pressure adjustment by the pressure adjustment unit 310 falls outside the second allowable range. When the first abnormality is detected by the detection unit 232, the control unit 233 changes the pressing start time, which is included in the pressing conditions, when the crimping head 203 presses the component 160 against the substrate 150, and then performs pressing with the crimping head 203.

[0158] According to this, the control unit 233 can change the pressing conditions so that the component 160 is pressed onto the substrate 150 at the appropriate timing. Therefore, the component crimping device 200 can continue production even if an abnormality occurs in the pressure adjustment time.

[0159] For example, the measuring unit 320 is a flow meter installed in the piping 330.

[0160] According to this, the component crimping device 200 can detect abnormalities using a flow meter.

[0161] Furthermore, the component crimping method according to the embodiment includes a crimping head 203 that presses the component 160 onto the substrate 150, a cylinder 205 that applies the pressing force to the crimping head 203 when the crimping head 203 presses the component 160 onto the substrate 150, a pressure adjustment unit 310 connected to an air source 300 that supplies air to generate the pressing force to the cylinder 205 and adjusts the pressure of the air supplied from the air source 300, and a pipe 330 that supplies the air adjusted by the pressure adjustment unit 310 to the cylinder 205. A component crimping method performed by a component crimping device 200, which includes a measuring unit 320 for measuring the air pressure or air flow rate inside a pipe 330, wherein the crimping head 203 is controlled based on the pressing conditions when the crimping head 203 presses the component 160 against the substrate 150, thereby performing pressing by the crimping head 203 (S140), and if a first abnormality is detected based on the measurement value measured by the measuring unit 320 (Yes in S130), the pressing conditions are changed (S150).

[0162] According to this, it will have the same effect as the component crimping device 200.

[0163] (Other embodiments) Although the component crimping device and the like according to this embodiment have been described above based on the above embodiment, the present invention is not limited to the above embodiment.

[0164] For example, in the above embodiment, the component crimping device 200 is equipped with one crimping head 203, but it may be equipped with multiple crimping heads. For example, if the component crimping device is equipped with multiple sets of crimping heads and cylinders, and each set is controlled (height controlled) by one motor, then the total value of the pressing force generated by each cylinder may be used to determine whether each cylinder is functioning normally.

[0165] Furthermore, for example, the motor 214 may be a pulse motor or a linear motor instead of a servo motor.

[0166] Furthermore, the encoder used to detect the amount of rotation of the motor 214 may be a rotary encoder provided on the motor 214, or a linear encoder provided separately from the motor 214.

[0167] Furthermore, for example, in the above embodiment, all or part of the components of the processing unit provided by the control device 230 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 (Central Processing Unit) or processor reading and executing a software program recorded on a recording medium such as an HDD or semiconductor memory.

[0168] Furthermore, the processing unit of the control device 230 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.

[0169] One or more electronic circuits may include, for example, semiconductor devices, ICs, or LSIs (Large Scale Integrations). ICs or LSIs may be integrated on a single chip or on multiple chips. 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). Field Programmable Gate Arrays (FPGAs), which are programmed after the LSI is manufactured, can also be used for the same purpose.

[0170] Furthermore, the present invention also includes forms obtained by applying various modifications to each embodiment that a person skilled in the art could conceive, as well as forms realized by arbitrarily combining the components and functions of each embodiment without departing from the spirit of the present invention.
