[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The present application embodiment discloses a micro circuit board welding jig. Figure 1 and Figure 2 The micro-circuit board welding jig includes a jig pallet 1, which has a plurality of circuit board fixing units 2 arranged in an array at intervals. Each circuit board fixing unit 2 is used to fix and clamp a micro-circuit board to be welded. The circuit board fixing unit 2 includes a snap-fitting groove 21 that is adapted to the shape of the micro-circuit board. A sliding groove 22 is provided at one corner of the snap-fitting groove 21. A tightening block 23 is slidably assembled in the sliding groove 22. An end of the sliding groove 22 away from the snap-fitting groove 21 is connected to a mounting groove 24. An elastic member 25 is provided in the mounting groove 24 to drive the tightening block 23 to slide toward the snap-fitting groove 21. The elastic member 25 is located in the mounting groove 24.

[0035] The beneficial technical effects of the micro circuit board welding jig of the embodiment of the present application are roughly as follows:

[0036] The staff uses their fingers to move the clamping piece away from the clamping groove 21 and places the micro circuit board in the clamping groove 21. The elastic restoring force of the elastic piece 25 drives the clamping block 23 to slide and fix the micro circuit board in the clamping groove 21. The staff does not need to use their fingers or other tools to press and fix it, which facilitates subsequent welding work and indirectly improves the circuit board production efficiency.

[0037] In this embodiment, the elastic member 25 is a cross torsion spring formed by bending a steel wire. One side of the cross torsion spring has a first arc support portion 251, which abuts against a side wall of the clamping block 23. The other side of the cross torsion spring has two second arc support portions 252, which abut against an inner wall of one side of the mounting groove 24.

[0038] The elastic member 25 of the above design has a simple structure, is easy to manufacture, has a strong elastic force, and is stable and not easy to loosen after being installed in the installation groove 24.

[0039] In order to facilitate the staff to remove the micro circuit board after welding, the snap-in groove 21 is rectangular, and the corners of the snap-in groove 21 that are not connected to the sliding groove 22 are connected and provided with circular grooves 26. The circular grooves 26 are used to pry up the micro circuit board. Furthermore, a rectangular picking and placing groove 27 is also provided on one side of the snap-in groove 21. The rectangular picking and placing groove 27 is connected to the snap-in groove 21 and is perpendicular to each other.

[0040] In this embodiment, in order to make the weight of the entire micro circuit board welding jig lighter, the jig support plate 1 is also provided with a plurality of weight-reducing holes 3, which are located in the gaps between adjacent circuit board fixing units 2. In order to clearly show the structure of the circuit board fixing unit 2, Figure 2 The weight-reducing hole 3 is not drawn according to the actual situation.

[0041] Reference Figure 2 and Figure 3 A first fixing groove 2321 is provided on one side wall of the abutting block 23, into which the first arc support portion 251 is inserted. Two second fixing grooves 241 are provided on one inner wall of the mounting groove 24, into which the two second arc support portions 252 are respectively inserted. This design facilitates quick and secure installation of the elastic member 25 in the mounting groove 24.

[0042] In this embodiment, the clamping block 23 includes a clamping plate 231 and a toggle plate 232. The toggle plate 232 and the clamping plate 231 are arranged vertically, and the clamping plate 231 is parallel to the fixture support plate 1. The toggle plate 232 is located at one end of the clamping plate 231 close to the elastic member 25.

[0043] The pressing block 23 further includes two slide bars 233 , which are respectively located at the bottom of two opposite sides of the pressing plate 231 . The opposite inner side walls of the sliding groove 22 are provided with track grooves 221 adapted to the slide bars 233 .

[0044] A U-shaped notch 2311 is provided at one end of the pressing plate 231 away from the toggle plate 232 . The U-shaped notch 2311 is used to fit the corner of the micro-circuit board. A round hole 2312 is also provided on the pressing plate 231 .

[0045] The above-designed clamping block 23 has a simple structure, is easy to manufacture, has a low manufacturing cost, and slides very stably. The design of the U-shaped notch 2311 is more adaptable to micro circuit boards of various sizes and models. The toggle plate 232 also makes it convenient for staff to toggle the clamping block 23 as needed, and the operation is simple and convenient.

[0046] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
