In the mainboard production process, the welding process is a key link, and the welding fixture is an important tool to ensure the welding quality.

[0003] At present, most of the mainboard welding fixtures on the market are made by profiling CNC, that is, special welding fixtures are designed and manufactured according to different models of mainboards. This production method has the following shortcomings:

[0004] ①High production cost: since each model of mainboard needs to be designed and manufactured separately, the production cost increases.

[0005] ②Long production cycle: from design to production of fixture, the whole process takes a long time, which cannot meet the requirements of rapid response to market demand.

[0006] ③High storage management cost: different models of mainboard welding fixtures cannot be used universally, which leads to the need for enterprises to equip a large number of different models of welding fixtures when producing various products, occupying space and increasing management difficulty.

[0007] Therefore, it is necessary to improve the existing welding fixture to solve the problem of low universality.

[0008] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and therefore can contain information that is not prior art known to those of ordinary skill in the art. UTILITY MODEL CONTENT

[0041] The utility model provides a adjustable mainboard fixed jig, it is applicable to the application scene of clamping and fixing mainboard to carry out the welding operation on the mainboard, it can effectively solve the many problems caused by the lower universality of the prior art welding jig.

[0042] Referring to Figure 1 In the embodiment, the adjustable mainboard fixed jig comprises a jig base 1 and a plurality of elastic clamping modules 2. Optionally, the number of elastic clamping modules 2 is two, and the two elastic clamping modules 2 are arranged at intervals.

[0043] The edge position of the jig base 1 is provided with a horizontal support surface 101 for supporting the bottom surface of the edge position of the mainboard, and a vertical positioning surface 102 for abutting the side surface of the edge position of the mainboard; the elastic clamping module 2 is rotatably installed on the jig base 1 and clamps the edge position of the mainboard under the action of the elastic force in cooperation with the horizontal support surface 101.

[0044] The adjustable mainboard fixed jig provided by the utility model can realize the positioning of the mainboard by placing the edge position of the mainboard on the horizontal support surface 101 and making the side surface of the mainboard abut against the vertical positioning surface 102, and then the elastic clamping module 2 clamps the edge position of the mainboard under the action of the elastic force in cooperation with the horizontal support surface 101, so that the fixing operation of the mainboard is completed.

[0045] In the above process, the elastic clamping module 2 and the jig base 1 clamp the edge position of the mainboard. Generally, the edge position of most circuit boards is provided with a blank area, and the blank area is not designed with any circuit pattern and electronic device. Therefore, clamping the edge position of the circuit board to realize the fixation of the circuit board can make the adjustable mainboard fixed jig provided by the utility model applicable to all mainboards with blank edge positions, greatly improving the universality of the adjustable mainboard fixed jig, and further solving the many problems caused by the lower universality of the prior art welding jig.
