Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0025] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] refer to Figure 1The circuit board welding tool shown includes: a base 1, a top surface of the base 1 is provided with a placement groove 2 adapted to the circuit board, and one side of the placement groove 2 extends to the side of the base 1; the base 1 is provided with a clamping plate 3 on the placement groove 2, and the clamping plate 3 is used to limit the movement of the circuit board placed in the placement groove 2. In this way, the base 1 is fixed on the welding station. During welding, the circuit board is inserted into the placement groove 2 from the side of the placement groove 2 (that is, the side of the base 1). During the welding process, the placement groove 2 limits the circuit board, and the clamping plate 3 limits the movement of the circuit board, ensuring that the circuit board will not move during the welding process, thereby improving the stability during welding and improving the welding yield.

[0028] refer to Figure 1 As shown, in order to further improve the stability of the circuit board when it is placed in the placement slot 2, two clamping plates 3 are provided, which are respectively arranged on both sides of the placement slot 2 to restrict the circuit board from both sides, so that the force on the circuit board is balanced, thereby improving the stability when welding the circuit board.

[0029] refer to Figure 1-2 As shown, in order for the circuit board to be smoothly placed in the placement slot 2, the base 1 is provided with a top plate 4 on both sides of the placement slot 2, and a movable cavity 5 is formed between the top plate 4 and the base 1, and two card plates 3 are movably arranged in the movable cavity 5 respectively. In this way, when the circuit board is inserted into the placement slot 2, the two card plates 3 are pressed into the movable cavity 5, so that the circuit board can be smoothly placed in the placement slot 2, and in order to facilitate the disassembly and assembly of the top plate 4, the top plate 4 is installed on the base 1 by bolts.

[0030] refer to Figure 1-2 As shown, in order to prevent the circuit board in the placement slot 2 from moving during processing, a mounting plate 6 is provided on the side of the movable cavity 5 away from the placement slot 2, and an elastic member 7 is provided between the mounting plate 6 and the card plate 3 on the same side. In this way, after the circuit board is placed in the placement slot 2, the elastic force of the elastic member 7 causes the two card plates 3 to move toward one side of the circuit board, clamping the two sides of the circuit board to prevent the circuit board from moving, wherein the elastic member 7 can be composed of multiple springs.

[0031] refer to Figure 1-2 As shown, a card slot 31 adapted to the edge shape of the circuit board is provided on the side where the two card boards 3 are close to each other. In this way, when fixing the circuit board, the card board 3 fits with the edge of the circuit board, so that the circuit board is more stably fixed on the base 1. In addition, in order to prevent the circuit board from moving upward during welding, a limit plate 32 is left on the top of the card slot 31 of the card board 3. In this way, the limit plates 32 on the two card boards 3 are clamped on the upper edge of the circuit board to limit the upward movement of the circuit board.

[0032] refer to Figure 1 As shown, in order to facilitate the installation of the base 1 on the processing station, a plurality of installation holes 11 are opened on the base 1, so that the base 1 can be installed by passing bolts through the installation holes 11.

[0033] Further optimization is to refer to Figure 1-2 As shown, in order to facilitate the insertion of the circuit board, the base 1 is provided with guiding slopes 12 on both sides of the side opening of the placement slot 2, so that the opening of the placement slot 2 is enlarged, the circuit board is conveniently connected to the placement slot 2, and the work efficiency is improved.

[0034] In summary, when in use, the base 1 is fixed on the welding station. When welding, the circuit board is inserted into the placement slot 2 from the side of the placement slot 2. During the welding process, the placement slot 2 limits the circuit board, and the clamping plate 3 limits the movement of the circuit board to ensure that the circuit board will not move during the welding process, thereby improving the stability during welding, making the welding operation more precise, and improving the welding yield.
