[0002] At present, when elastic electrical connectors are arranged in an anti-shake motor to connect two circuit substrates, multiple elastic electrical connectors are usually soldered to the circuit substrates by reflow soldering. The process of reflow soldering is simple and mature, and has the advantage of low cost. However, reflow soldering also has the problem of poor thickness uniformity of solder paste, which leads to a large gap between the elastic electrical connector and the circuit substrate and uneven gap thickness, which makes it difficult to control the stability of the product thickness, and is particularly unfavorable for the design and manufacture of thin anti-shake motors.

[0003] Furthermore, when the elastic electrical connector is welded to the circuit substrate, since the elastic electrical connector is easily deformed or warped, the problem of abnormal alignment is likely to occur during the welding process, thus affecting the welding quality.

[0004] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art. Summary of the invention

[0005] The purpose of the present invention is to provide an assembly device, an assembly method and an elastic electrical connection component of an elastic electrical connection, which can make the gap between the elastic connection component and the circuit substrate small and the thickness uniform, and can also overcome the problem of abnormal alignment of the elastic electrical connection component during welding.

[0006] To achieve the above object, the present invention provides an assembly device for an elastic electrical connector, which is used to assemble the elastic electrical connector onto a substrate, comprising:

[0007] A fixing agent, wherein the fixing agent fixes the elastic electrical connector on the substrate;

[0009] A bonding machine is used to fix two ends of the metal wire on the elastic electrical connector and the substrate respectively.

[0010] Optionally, the fixing agent is an adhesive material, and the adhesive material is coated on the upper surface of the substrate or the lower surface of the elastic electrical connector.

[0011] Optionally, the assembling device further comprises a packaging material, wherein the packaging material wraps the metal wire.

[0015] A bonding machine is used to fix the two ends of the metal wire to the pads of the elastic electrical connector and the pads of the substrate respectively.

[0016] Optionally, after fixing two ends of the metal wire on the pad of the elastic electrical connector and the pad of the substrate respectively, the metal wire is wrapped with a packaging material.

[0017] Optionally, the fixing method is to apply the adhesive material on the upper surface of the substrate or the lower surface of the elastic electrical connector.

[0018] The present invention also provides an elastic electrical connection assembly, comprising:

[0019] An elastic electrical connector, wherein a solder pad is provided on the elastic electrical connector;

In this process, since the fixing agent relatively fixes the elastic electrical connector and the substrate, on the one hand, the bonding strength between the elastic electrical connector and the substrate is enhanced, and the problem of abnormal alignment is not easy to occur, thereby improving the stability and reliability of wire bonding, and then improving the electrical connection stability between the elastic electrical connector and the substrate. On the other hand, since the thickness of the fixing agent is controllable, the gap between multiple elastic electrical connectors and the substrate is small and uniform enough, thereby improving the assembly accuracy of the elastic electrical connection component, which is beneficial to the design and manufacture of thin motors.

[0026] The technical solutions, structural features, achieved objectives and effects of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] It should be noted that the drawings are in a very simplified form and use non-precise proportions. They are only used to conveniently and clearly assist in explaining the embodiments of the present invention, and are not used to limit the conditions for the implementation of the present invention. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present invention.

[0028] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0029] The elastic electrical connector is an electrical connector with a certain length and elasticity, which can be electrically connected between two circuit substrates or between a circuit substrate and an electrical device to transmit electrical signals. At present, the elastic electrical connector is usually welded on the circuit substrate by reflow soldering. The reflow soldering process usually includes steps such as printing solder paste, placing components, preheating, reflow and cooling. Since multiple elastic electrical connectors need to be welded on each circuit substrate, solder paste needs to be placed at multiple welding points for welding. This process will cause the problem of poor uniformity of solder paste thickness, which in turn leads to a large gap between the elastic electrical connector and the circuit substrate and uneven gap thickness, which makes it difficult to control the stability of the product thickness, especially not conducive to the design and manufacture of thin anti-shake motors. In addition, when the elastic electrical connector is welded on the circuit substrate, since the elastic electrical connector is easily deformed or warped, it is easy to cause abnormal alignment during the welding process, affecting the welding quality.

[0030] In order to solve the above problems, the present invention discloses an assembly device, an assembly method and an elastic electrical connection assembly of an elastic electrical connector. The assembly device of the elastic electrical connector is used to assemble the elastic electrical connector to a substrate, and includes: a fixing agent for fixing the elastic electrical connector on the substrate, a metal wire connecting the elastic electrical connector and the substrate to achieve electrical conduction, and a bonding machine for fixing the two ends of the metal wire on the elastic electrical connector and the substrate respectively; the assembly method of the elastic electrical connector using the assembly device includes the steps of: fixing the elastic electrical connector on the substrate using a fixing agent, and then fixing the two ends of the metal wire on the substrate and the elastic electrical connector respectively using a bonding machine. Through the assembly device and the assembly method, the electrical connection stability between the elastic electrical connector and the substrate is improved, and the gaps between multiple elastic electrical connectors and the substrate can be made sufficiently small and uniform, thereby improving the accuracy of the elastic electrical connection assembly.

[0031] The scheme of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figure 1 As shown, an assembly device of an elastic electrical connector according to an embodiment of the present invention is used to assemble the elastic electrical connector 20 onto the substrate 10. The assembly device includes: a fixing agent 30, which can fix the elastic electrical connector 20 on the substrate 10; a metal wire 40, which can be, for example, a gold wire, an aluminum wire, etc., and the metal wire 40 connects the elastic electrical connector 20 and the substrate 10 to achieve electrical conduction between the two; a bonding machine (not shown in the figure), which can fix the two ends of the metal wire 40 on the elastic electrical connector 20 and the substrate 10 respectively, that is, to achieve wire bonding.

[0033] The substrate 10 is provided with a first pad 11, and the elastic electrical connector 20 is correspondingly provided with a second pad 21. When the substrate 10 and the elastic electrical connector 20 are connected, the positions of the first pad 11 and the second pad 21 are staggered and have a certain distance. The first end of the metal wire 40 and the first pad 11, as well as the second end of the metal wire 40 and the second pad 21, are connected by a wire bonding process implemented by a bonding machine. Compared with connecting the first pad 11 and the second pad 21 by a solder paste welding process, connecting the first pad 11 and the second pad 21 by a metal wire 40 helps to reduce the gap between the substrate 10 and the elastic electrical connector 20.

[0034] The fixing agent 30 may be an adhesive material, such as a thermosetting adhesive or a structural adhesive. The adhesive material is applied between the substrate 10 and the elastic electrical connector 20. Specifically, the adhesive material is applied on the first surface of the substrate 10 or the second surface of the elastic electrical connector 20, and then the elastic electrical connector 20 is placed on the second surface of the substrate 10 so that the first surface of the substrate 10 is opposite to the second surface of the elastic electrical connector 20, so that the adhesive material is between the substrate 10 and the elastic electrical connector 20, and then the elastic electrical connector 20 is fixed to the substrate 10 through the adhesive material. In this embodiment, the elastic electrical connector 20 is arranged above the substrate 10, and the adhesive material is applied on the upper surface of the substrate 10 or the lower surface of the elastic electrical connector 20.

[0035] It should be noted that the fixing agent 30 does not need to cover the entire lower surface of the elastic electrical connector 20. The lower surface of the elastic electrical connector 20 located above the substrate 10 only needs to cover the second solder pad 21 on the elastic electrical connector 20, so that the elastic electrical connector 20 located above the substrate 10 is fixed without warping or deformation, thereby preventing the occurrence of abnormal alignment during wire bonding, which may lead to poor electrical connection stability.

[0036] In actual applications, each substrate 10 is connected to a plurality of elastic electrical connectors 20. In the prior art, it is difficult to control the gaps between the plurality of elastic electrical connectors 20 and the substrate 10 to be uniform. In this embodiment, a metal wire 40 is used to connect the two, and a fixing agent 30 is used to fix the elastic electrical connector 20 on the substrate 10. The amount and thickness of the fixing agent 30 are controllable. Therefore, the gap between the elastic electrical connector 20 and the substrate 10 is controllable and can be made small and uniform enough, which is conducive to the design and manufacture of thin motors.

[0037] Furthermore, the assembly device of the elastic electrical connector of the present embodiment further includes a packaging material, and the packaging material wraps the metal wire 40. After the substrate 10 and the elastic electrical connector 20 are connected by a wire bonding process using a bonding machine, the packaging material is used to wrap the metal wire 40, which, on the one hand, plays a role of electrical isolation to avoid short circuits between different metal wires 40, and on the other hand, plays a role of protecting the metal wire 40 to extend its service life.

[0038] Based on the above-mentioned assembly device of the elastic electrical connector, the present invention also proposes an assembly method of the elastic electrical connector, comprising the following steps:

[0039] Placing the elastic electrical connector 20 on the upper surface of the substrate 10, and fixing the elastic electrical connector 20 and the substrate 10 with a fixing agent 30;

[0040] The two ends of the metal wire 40 are fixed on the second pad 21 of the elastic electrical connector 20 and the first pad 11 of the substrate 10 respectively by using a bonding machine.

[0041] Furthermore, after the two ends of the metal wire 40 are respectively fixed on the second pad 21 of the elastic electrical connector 20 and the first pad 11 of the substrate 10 , the metal wire 40 is wrapped with a packaging material.

[0042] Among them, the specific fixing method of fixing the elastic electrical connector 20 and the substrate 10 with the fixing agent 30 is: applying glue on the upper surface of the substrate 10 or the lower surface of the elastic electrical connector 20, and then placing the elastic electrical connector 20 on the substrate 10 so that the upper surface of the substrate 10 and the lower surface of the elastic electrical connector 20 are opposite.

[0043] Based on the assembly method of the elastic electrical connector, the present invention also proposes an elastic electrical connection assembly, such as Figure 2 As shown, the elastic electrical connection component includes: an elastic electrical connector 20, on which a second soldering pad is provided at the first end 22 of the elastic electrical connector 20; and a first substrate 12, on which a first soldering pad is provided. The first end 22 of the elastic electrical connector 20 is fixed to the first substrate 12 by the assembly method of the elastic electrical connector, that is, the glue material is coated on the upper surface of the first substrate 12 or the lower surface of the first end 22 of the elastic electrical connector 20, and then the elastic electrical connector 20 is placed on the first substrate 12 for fixation, and then the two ends of the metal wire 40 are fixed to the second soldering pad of the first end 22 of the elastic electrical connector 20 and the first soldering pad of the first substrate 12 respectively by using a bonding machine.

[0044] The elastic electrical connection component also includes a second substrate 13, on which a third solder pad is provided, and correspondingly, a fourth solder pad is provided on the second end 23 of the elastic electrical connection member 20; the second end 23 of the elastic electrical connection member 20 is also fixed to the second substrate 13 by the assembly method of the elastic electrical connection member, that is, the glue material is coated on the upper surface of the second substrate 13 or the lower surface of the second end 23 of the elastic electrical connection member 20, and then the elastic electrical connection member 20 is placed on the second substrate 13 for fixation, and then a bonding machine is used to fix the two ends of the metal wire 40 to the fourth solder pad of the second end 23 of the elastic electrical connection member 20 and the third solder pad of the second substrate 13 respectively.

[0045] The first substrate 12 and the second substrate 13 are connected via a plurality of elastic electrical connectors 20. Except for the two end pads of the elastic electrical connector 20 which are fixed parts, the other parts are movable parts, so the elastic electrical connector 20 can still exert its elasticity.

After reading the above content, it will be apparent to those skilled in the art that various modifications and substitutions of the present invention will occur. Therefore, the protection scope of the present invention should be limited by the appended claims.
