[0023] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom...) in the embodiments of the present utility model are only used to explain the relative positional relationship between components in a certain specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indication will also change accordingly.

[0025] It should also be noted that when an element is referred to as "fixed to" or "disposed on" another element, the element can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0026] Please refer to Figures 1 to 6 , a bridge chip and bridge strip welding positioning jig 10 provided by an embodiment of the present utility model includes a base 12 and a pressing plate 14. The base 12 is used to support the bridge chip 13 and the bridge strip 15. The pressing plate 14 is disposed on one side of the base 12 and clamps the bridge chip 13 and the bridge strip 15 between the base 12 and the pressing plate 14.

[0027] A receiving groove 16 and a positioning hole 18 are provided on one side of the base 12 close to the pressing plate 14. The positioning hole 18 is arranged along the extending direction of the receiving groove 16. The receiving groove 16 is used to accommodate the bridge strip 15, and the positioning hole 18 is used to accommodate the bridge chip 13 to form a positioning effect on the bridge strip 15 and the bridge chip 13. When placing the bridge strip 15 and the bridge chip 13 on the base 12, the bridge chip 13 can be first placed in the positioning hole 18, and then the bridge strip 15 is placed in the receiving groove 16 so that the bridge strip 15 passes above the bridge chip 13.

[0028] The specific number of the receiving groove 16 and the positioning hole 18 is not limited. In this embodiment, the number of the receiving grooves 16 is two. The two receiving grooves 16 are spaced parallel to each other. A plurality of spaced positioning holes 18 are arranged along the extending direction of each receiving groove 16, so that each bridge strip 15 can contact a plurality of bridge chips 13 to improve the processing efficiency.

[0029] A limiting portion 20 is provided in the positioning hole 18 to prevent the bridge chip 13 from rotating in the positioning hole 18. The bridge chip 13 is circular ring-shaped and is provided with a central hole and a limiting groove communicating with the central hole. The limiting portion 20 is inserted into the limiting groove to prevent the bridge chip 13 from rotating and enhance the stability of the bridge chip 13.

[0030] In one embodiment, an extrusion member 22 is provided on one side of the pressing plate 14 facing the base 12. The extrusion member 22 protrudes from the surface of the pressing plate 14. The base 12 is provided with an avoidance hole 24 corresponding to the extrusion member 22. The avoidance hole 24 is located below the positioning hole 18 and communicates with the positioning hole 18. The extrusion member 22 is used to extrude the bridge strip 15 so that the bridge strip 15 deforms relative to the bridge piece 13 towards the direction of the avoidance hole 24. The avoidance hole 24 is located below the central hole, and the extrusion member 22 corresponds to the central hole. Therefore, during the process of assembling the pressing plate 14 and the base 12, the extrusion member 22 on the pressing plate 14 will extrude the bridge strip 15, pressing the bridge strip 15 downward so that the bridge strip 15 deforms through the central hole on the bridge piece 13 towards the direction of the avoidance hole 24, thereby changing the length of the connecting part between the bridge strip 15 and the bridge piece 13 to make the resistance value meet the requirements. During the processing, workers do not need to manually bend the bridge strip 15, which not only improves the processing efficiency, but also reduces manual errors and improves product quality.

[0031] Specifically, the number of pressing plates 14 is two. Each pressing plate 14 has a plurality of extrusion members 22, and each corresponds to a corresponding positioning hole 18.

[0032] In one embodiment, the extrusion member 22 is detachably connected to the pressing plate 14. Therefore, the operator can change the pressing height of the extrusion member 22 by replacing the extrusion members 22 with different lengths, thereby adjusting the resistance value to broaden the applicable scenarios. Specifically, the extrusion member 22 is a pin detachably connected to the pressing plate 14.

[0033] In another embodiment, the extrusion member 22 is movably matched with the pressing plate 14 so that the extrusion member 22 can move relative to the pressing plate 14 to adjust the protruding length of the extrusion member 22 relative to the pressing plate 14, which can also achieve the effect of changing the pressing height of the extrusion member 22. Specifically, the extrusion member 22 is a screw, and the screw is threadedly matched with the pressing plate 14. Therefore, the protruding length of the screw can be adjusted by rotating the screw.

[0034] In one embodiment, a pressing member (not shown in the figure) is provided between the pressing plate 14 and the base 12. The pressing member is used to press the bridge strip 15 against the base 12 to enhance the stability of the bridge strip 15, prevent the bridge strip 15 from separating from the base 12, and at the same time reduce the risk that the bridge strip 15 shakes during processing and affects the processing effect.

[0035] Specifically, before installing the pressing plate 14 onto the base 12, the pressing member will form a downward pressure on the bridge strip 15 to press the bridge strip 15 against the base 12, but at this time, the bridge strip 15 will not be completely fixed. During the process of installing the pressing plate 14 onto the base 12, the extrusion member 22 on the pressing plate 14 will extrude the bridge strip 15 and cause the bridge strip 15 to deform. During the deformation process of the bridge strip 15, a sliding effect will be formed in the receiving groove 16. That is, the pressing member can prevent the bridge strip 15 from exiting the receiving groove 16, but will not affect the sliding of the bridge strip 15 in the receiving groove 16.

[0036] The specific material of the pressing member is not limited. In this embodiment, the pressing member is a rubber pad, which is relatively soft and will not form a rigid contact with the bridge strip 15, preventing damage to the bridge strip 15.

[0037] The number of pressing members is multiple. Any one of the positioning holes 18 is provided with pressing members on the opposite sides in the extending direction of the receiving groove 16, so as to form a pressing effect on both ends of the part of the bridge strip 15 that cooperates with each bridge piece 13.

[0038] The base 12 and / or the pressing plate 14 are provided with recessed portions 26 for accommodating the pressing members, so as to enhance the compactness of the overall structure. Specifically, both the base 12 and the pressing plate 14 are provided with recessed portions 26, and the recessed portions 26 on the base 12 correspond to the recessed portions 26 on the pressing plate 14 one by one. Part of the pressing member is received in the recessed portion 26 of the base 12, and the other part is received in the recessed portion 26 of the pressing plate 14.

[0039] In one embodiment, the pressing plate 14 is provided with a plurality of through holes 28 arranged at intervals. The pressing member 22 is located between two adjacent through holes 28. The through holes 28 are used to expose the contact part of the bridge strip 15 and the bridge piece 13 for welding operation.

[0040] In one embodiment, the pressing plate 14 and the base 12 are magnetically coupled. When the pressing plate 14 approaches the base 12, the pressing plate 14 and the base 12 will attract each other, so as to magnetically fix the pressing plate 14 on the base 12. The magnetic coupling method makes the disassembly and assembly operations of the pressing plate 14 and the base 12 simple and convenient to use. Moreover, after the two are magnetically attracted together, the pressing member will be clamped between the pressing plate 14 and the base 12.

[0041] It can be understood that the magnetic coupling between the pressing plate 14 and the base 12 can be achieved by setting magnetic members on both the pressing plate 14 and the base 12, or by setting a magnetic member on one of them and the other being a metal member that can be attracted by the magnetic member. In this embodiment, the base 12 is provided with a magnetic member (not shown in the figure), and the pressing plate 14 is a metal member that can be attracted by the magnetic member.

[0042] In this embodiment, the base 12 is provided with mounting holes 30, and the magnetic members are arranged in the mounting holes 30. Specifically, the mounting holes 30 are provided on the side of the base 12 away from the pressing plate 14 and below the recessed portion 26.

[0043] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
