[0006] Problems to be solved by the invention

[0007] However, in recent years, there have been substrates with components such as free-form displays arranged along curved edges. For such substrates, it is not possible to crimp multiple heads arranged in a straight line at once. Therefore, a method is adopted to crimp the components arranged on the curve one by one while changing the relative position relationship between the substrate and the tool. As a result, the production cycle time for crimping all components on the substrate becomes longer and productivity decreases.

[0008] Therefore, the present invention provides a component crimping device and a component crimping method that can crimp components at once even on a substrate where components are arranged along a curved edge.

[0011] A component crimping method according to one embodiment of the present invention uses the first moving mechanism to change at least one of the positions of the base component possessed by the first crimping unit and the positions of the base component possessed by the second crimping unit according to multiple crimping locations of the substrate carried on the holding device, uses the second moving mechanism to change at least one of the positions of the base component possessed by the first crimping unit and the positions of the base component possessed by the second crimping unit according to multiple crimping locations of the substrate carried on the holding device, uses the posture changing mechanism to change at least one of the postures of the crimping head possessed by the first crimping unit and the postures of the crimping head possessed by the second crimping unit according to multiple crimping locations of the substrate carried on the holding device, and crimps each of the components arranged at the crimping locations of the substrate at one time using the crimping head possessed by the first crimping unit and the crimping head possessed by the second crimping unit.

[0012] It should be noted that the above general or specific solutions may also be implemented by systems, devices, methods, integrated circuits, computer programs, or computer-readable recording media such as recording disks, or by any combination of systems, devices, methods, integrated circuits, computer programs, and recording media. Computer-readable recording media include, for example, non-volatile recording media such as CD-ROMs (Compact Disc-Read Only Memory).

[0013] Effects of the Invention

[0014] According to the component crimping device of the present invention, even if the components to be crimped are not arranged on a straight line, a plurality of components can be crimped at one time, thereby improving productivity.

[0057] In a component crimping device in which a plurality of crimping units are arranged on a straight line, components arranged on a curve cannot be crimped at one time. In addition, a component crimping device having a plurality of crimping units arranged to crimp components arranged on a curve at one time cannot cope with a variety of substrates.

[0058] However, if a plurality of components cannot be crimped to a plurality of substrates at one time, the productivity will be negatively affected. Therefore, the present inventors have made a component crimping device that can crimp components to a plurality of substrates at one time as described below.

[0059] For example, a first scheme of the component crimping device of the present invention is provided with: a holding device that holds a substrate for crimping components to a plurality of crimping locations; a first crimping unit and a second crimping unit that crimp the components to the substrate; and a stand on which the first crimping unit and the second crimping unit are mounted, the first crimping unit and the second crimping unit respectively having: a base member; and a crimping head that can move relative to the base member in the crimping direction of the component, at least one of the first crimping unit and the second crimping unit having: a first moving mechanism that holds the base member so that it can move relative to the stand in a first direction that is a direction approaching or moving away from the holding device; a second moving mechanism that holds the base member so that it can move relative to the stand in a second direction that intersects the crimping direction and the first direction; and a posture changing mechanism that changes the posture of the crimping head within a plane including the first direction and the second direction. According to the above first scheme, by changing the position and posture of at least one of the first crimping unit and the second crimping unit, it is possible to crimp components arranged on a curve at one time in response to a variety of substrates.

[0060] The second scheme of the component crimping device of the present invention includes the first scheme, and it can also be that the first crimping unit and the second crimping unit respectively have supporting components, and the supporting components are installed on the base component in a manner that is arranged on the opposite side of the crimping head relative to the substrate carried on the holding device, and support the crimping part.

[0061] According to the second aspect, when the posture of one of the first crimping unit and the second crimping unit is changed, the support member also changes its posture together with the crimping head. Therefore, the relative positional relationship and relative posture relationship between the support member and the crimping head can be maintained constant.

[0062] A third aspect of the component crimping device of the present invention includes the second aspect, and the posture changing mechanism may change the postures of the crimping head and the supporting member by changing the posture of the base member within a plane including the first direction and the second direction.

[0063] According to the third aspect, since the posture of the support member and the posture of the crimping head are structurally constant, stable crimping of components can be achieved even for various substrates.

[0064] The fourth scheme of the component crimping device of the present invention includes the second scheme, and the posture changing mechanism may include: a first posture changing mechanism, which is installed on the base component and changes the posture of the crimping head; and a second posture changing mechanism, which is installed on the base component and changes the posture of the supporting component.

[0065] According to the fourth aspect, the electronic component can be crimped without changing the postures of the support member and the parts other than the crimping head, so that the posture changing mechanism can be miniaturized.

[0066] A fifth scheme of the component crimping device of the present invention includes any one of the first scheme to the fourth scheme, and it may also be that the component crimping device has a control device that can independently control the movement of the crimping head possessed by the first crimping unit and the crimping head possessed by the second crimping unit, and the control device enables the crimping of the component performed by the crimping head possessed by the first crimping unit and the crimping of the component performed by the crimping head possessed by the second crimping unit to be performed at one time.

[0067] According to the fifth aspect, a plurality of components can also be crimped at a time, and crimping can also be performed by setting conditions individually.

[0068] The sixth scheme of the component crimping method of the present invention is a component crimping method using any one of the component crimping devices of the first scheme to the fifth scheme, wherein the first moving mechanism is used to change at least one of the positions of the base component possessed by the first crimping unit and the positions of the base component possessed by the second crimping unit according to the multiple crimping positions of the substrate loaded on the holding device, the second moving mechanism is used to change at least one of the positions of the base component possessed by the first crimping unit and the positions of the base component possessed by the second crimping unit according to the multiple crimping positions of the substrate loaded on the holding device, the posture changing mechanism is used to change at least one of the postures of the crimping head possessed by the first crimping unit and the postures of the crimping head possessed by the second crimping unit according to the multiple crimping positions of the substrate loaded on the holding device, and each of the components arranged at the crimping positions of the substrate are crimped at one time using the crimping head possessed by the first crimping unit and the crimping head possessed by the second crimping unit.

[0069] According to the sixth aspect, by changing the position and posture of at least one of the first crimping unit and the second crimping unit, it is possible to crimp components arranged on a curve at one time in response to a variety of substrates.

[0070] It should be noted that the above-mentioned general or specific solutions can also be implemented by systems, devices, methods, integrated circuits, computer programs or computer-readable recording disks and other recording media, and can also be implemented by any combination of systems, devices, methods, integrated circuits, computer programs and recording media. Computer-readable recording media include, for example, non-volatile recording media such as CD-ROMs. In addition, the device can be composed of more than one device. In the case where the device is composed of more than two devices, the two or more devices can be configured in one machine, or can be separately configured in two or more separate machines. In this specification and technical solution, "device" can mean not only one device, but also a system composed of multiple devices.

[0071] Hereinafter, the component crimping device of the present invention will be described with reference to the accompanying drawings. It should be noted that the embodiments described below all show general or specific examples. The numerical values, shapes, constituent elements, configurations of constituent elements, connection forms, steps (processes), order of steps, etc. shown in the following embodiments are examples, and their main purpose is not to limit the present invention. For example, they can be appropriately changed according to the specifications of the component crimping device and the use environment, etc. In addition, the constituent elements that are not recorded in the independent technical solutions representing the highest-level concepts in the constituent elements of the following embodiments are described as arbitrary constituent elements. In addition, each figure is a schematic diagram and is not necessarily strictly illustrated. Moreover, in each figure, the same figure mark is marked for substantially the same constituent elements, and repeated descriptions are sometimes omitted or simplified.

[0072] A component crimping device 100 according to the embodiment will be described. Figure 1 1 is a perspective view showing the component crimping device 100 before the substrate 200 is installed. Figure 2 2 is a perspective view showing the component crimping device 100 after the substrate 200 is installed. Figure 1 , Figure 2 As shown, the component crimping device 100 is a device for crimping a component 210 on a substrate 200, and includes a holding device 110, a crimping unit 120, and a stand 130. In the case of this embodiment, the component crimping device 100 fixes the component 210 to the substrate 200 by thermally crimping the component 210 mounted by means of an adhesive member, thereby ensuring electrical connection between the substrate 200 and the electronic component.

[0073] The substrate 200 is a plate-shaped member to which the components 210 are respectively crimped at a plurality of crimping locations 201. The type of the substrate 200 is not limited, and examples thereof include a liquid crystal panel and an organic or inorganic EL (Electroluminescence) panel. In the present embodiment, the substrate 200 has an edge 202 that is curved in a manner that bulges outward on at least one side when viewed from above (in the figure, the Z+ side is viewed from the Z- side), and has crimping locations 201 at a plurality of locations along the edge 202.

[0074] The component 210 is an electronic component, an electric component, or the like that is pressure-bonded to the substrate 200. The type of the component 210 is not limited, but an IC (Integrated Circuit) chip or the like can be exemplified, for example.

[0075] The component 210 is mounted on the substrate 200 by means of an adhesive member. The adhesive member may be arranged on the substrate 200 as a tape composed of ACF (anisotropic conductive film), or may be applied to the substrate 200 in a liquid or paste state as ACP (anisotropic conductive paste). ACF is a conductive film formed into a film by mixing conductive particles such as fine metal particles in a thermosetting resin. ACP is a paste in which conductive particles such as fine metal particles are mixed in a thermosetting resin. Such an adhesive member is fluidized by being pressurized and heated, and then solidified. The component 210 arranged on the adhesive member is pressed toward the substrate 200, so that the component 210 and the adhesive member are positioned and temporarily fixed to the substrate 200 under the action of the adhesive force of the adhesive member, that is, temporarily pressed to the substrate 200. It should be noted that the adhesive member may not contain conductive particles. In this case, the adhesive member may be disposed on substrate 200 as a tape made of NCF (Non Conductive Film) or the like, or may be applied to substrate 200 in a liquid or paste state as NCP (Non Conductive Paste) or the like.

[0076] The stand 130 is a basic structural member on which at least the crimping unit 120 is mounted. In the case of the present embodiment, the stand 130 has a plurality of crimping units 120 and the holding device 110 mounted thereon.

[0077] The holding device 110 is a device capable of holding the substrate 200 and moving the held substrate 200 to a predetermined position. In the case of the present embodiment, the holding device 110 holds the substrate 200 in a loading state. The holding device 110 can rotate the held substrate 200 around a vertical axis (Z axis in the figure), and can move the substrate 200 in a direction toward the crimping unit 120 (X axis direction in the figure) and in an arrangement direction of the crimping unit 120 (Y axis direction in the figure).

[0078] The crimping unit 120 is a device for crimping the component 210 placed on the crimping portion 201 to the substrate 200, and includes at least a first crimping unit 121 and a second crimping unit 122. In the case of this embodiment, the component crimping device 100 is a device capable of crimping six components 210 to the substrate 200 at one time, and includes a third crimping unit 123, a fourth crimping unit 124, a fifth crimping unit 125, and a sixth crimping unit 126. One-time crimping does not only mean that a plurality of components 210 are mounted on one substrate 200 at exactly the same time, but also includes slight deviations in crimping time and crimping timing due to the individuality of the crimping unit 120.

[0079] Figure 3 1 is a perspective view showing the first crimping unit 121. The first crimping unit 121 includes a base member 141, a crimping head 142, a first moving mechanism 143, a second moving mechanism 144, a posture changing mechanism 145, a pressing device 146, a driving device 147, and a supporting member 148. In the case of this embodiment, the second crimping unit 122 to the sixth crimping unit 126 each have the same structure as the first crimping unit 121.

[0080] The base member 141 is a member that forms the basis of the structure of the first crimping unit 121. The shape of the base member 141 is not limited. In the case of the present embodiment, the base member 141 is J-shaped in a side view (a state viewed from the Y-axis direction in the figure), and includes: a first columnar portion 151 that holds the crimping head 142 to be slidable; a second columnar portion 152 that holds the support member 148 fixedly; and a connecting portion 153 that integrally connects the lower end of the first columnar portion 151 and the lower end of the second columnar portion 152.

[0081] The crimping head 142 is a member that is movably mounted in the crimping direction (Z-axis direction in the figure) of the component 210 relative to the base member 141, and presses and crimps the component 210 to the substrate 200 provided on the support member 148. In the case of this embodiment, the crimping head 142 includes a heating portion (not shown) that can apply heat to the component 210 when pressing the component 210 to the substrate 200. That is, the crimping head 142 can perform thermal crimping.

[0082] The support member 148 is a member mounted on the base member 141 so as to be arranged on the opposite side of the crimping head 142 relative to the substrate 200 placed on the holding device 110, and is a member that supports the crimping portion 201 from below. The support member 148 is a member called a so-called back support or the like. The support member 148 may also include a heating portion (not shown) that can apply heat to the component 210 when the component 210 is pressed against the substrate 200.

[0083] The pressing device 146 is a device for applying a pressing force to the crimping head 142. The structure of the pressing device 146 is not limited. In the case of this embodiment, the pressing device 146 includes: a driving rod 154, which is fixed to the opposite side of the crimping head 142 relative to the first columnar portion 151 of the base member 141 and moves in the up-down direction under the action of hydraulic pressure, air pressure, etc.; and a transmission part 155, which transmits the pressing force of the driving rod 154 to the upper end of the crimping head 142.

[0084] The first moving mechanism 143 is a member that holds the base member 141 so as to be movable relative to the stage 130 along a first direction (X-axis direction in the figure) that is a direction approaching or moving away from the holding device 110. In the case of this embodiment, the first moving mechanism 143 has a first groove 156 on the lower surface that is embedded in a pair of first rails (not shown) provided on the upper surface of the second moving mechanism 144 and extending in the first direction, and can reciprocate relative to the second moving mechanism 144 in the first direction by a motor provided in the driving device 147.

[0085] The second moving mechanism 144 is a member that holds the base member 141 so that it can move relative to the stage 130 along the second direction (the Y-axis direction in the figure) intersecting the crimping direction (the Z-axis direction in the figure) and the first direction (the X-axis direction in the figure). In the case of this embodiment, the second moving mechanism 144 has a second groove 158 on the lower surface that is embedded in a pair of second rails 157 provided on the upper surface of the stage 130 and extending in the second direction, and can reciprocate relative to the stage 130 in the second direction by the motor provided in the driving device 147. The second rail 157 extends from the first crimping unit 121 to the sixth crimping unit 126, and is commonly used by all the crimping units 120.

[0086] The posture changing mechanism 145 is a member that changes the posture of the crimping head 142 in a plane including the first direction and the second direction (in the XY plane in the figure). In the case of the present embodiment, the posture changing mechanism 145 changes the posture of the crimping head 142 and the supporting member 148 by changing the posture of the base member 141 in a plane including the first direction and the second direction. That is, the posture changing mechanism 145 is arranged on the upper surface of the first moving mechanism 143 and supports the base member 141. The posture changing mechanism 145 rotates relative to the first moving mechanism 143 around a rotation axis extending in the crimping direction under the action of the motor provided by the driving device 147, thereby changing the posture of the crimping head 142 and the supporting member 148 in a plane including the first direction and the second direction with the help of the base member 141.

[0087] Figure 4 1 is a block diagram showing the control function of the component crimping device 100. The control device 160 independently controls the movement of each crimping head 142 provided in each of the first crimping unit 121 to the sixth crimping unit 126. The control device 160 is a computer having a processor such as a CPU (Central Processing Unit) and a DSP (Digital Signal Processor) and a memory. Some or all of the functions of the control device 160 are realized by executing a program by the processor.

[0088] In the case of this embodiment, the pressing devices 146 respectively provided in the first crimping unit 121 to the sixth crimping unit 126 are respectively connected to adjustment devices of the first adjustment device 161 to the sixth adjustment device 166, and the first adjustment device 161 to the sixth adjustment device 166 respectively adjust the protrusion amount (pressing force) of the driving rod 154 of each pressing device 146. The control device 160 controls the first to sixth adjustment devices 161 to 166 respectively, so that, for example, the crimping of the component 210 by the crimping head 142 of the first crimping unit 121, the crimping of the component 210 by the crimping head 142 of the second crimping unit 122, the crimping of the component 210 by the crimping head 142 of the third crimping unit 123, the crimping of the component 210 by the crimping head 142 of the fourth crimping unit 124, the crimping of the component 210 by the crimping head 142 of the fifth crimping unit 125, and the crimping of the component 210 by the crimping head 142 of the sixth crimping unit 126 can be performed at once. In addition, the control device 160 can also make the pressing force of each crimping head 142 different based on history or the like.

[0089] It should be noted that the present invention is not limited to the above-mentioned embodiments. For example, embodiments implemented by arbitrarily combining the constituent elements described in this specification, and other embodiments implemented by excluding some of the constituent elements can also be used as embodiments of the present disclosure. In addition, modifications obtained by applying various modifications thought of by those skilled in the art to the above-mentioned embodiments without departing from the gist of the present invention, that is, within the scope of the meaning expressed by the language described in the technical solution, are also included in the present invention.

[0090] For example, Figure 5 As shown, the posture changing mechanism 145 may also include: a first posture changing mechanism 171, which is installed on the base component 141 by means of the crimping movable part 173, and changes the posture of the crimping head 142 relative to the crimping movable part 173; and a second posture changing mechanism 172, which is installed on the upper end surface of the second columnar part 152 of the base component 141, and changes the posture of the supporting member 148.

[0091] Furthermore, although an embodiment has been described in which the first moving mechanism 143, the second moving mechanism 144, and the posture changing mechanism 145 are moved by the motor provided in the driving device 147, the first moving mechanism 143, the second moving mechanism 144, and the posture changing mechanism 145 may be moved manually.
