Technical Field

[0001] The utility model relates to the technical field of welding jigs, in particular to a circuit board welding jig. Background Art

[0002] A welding jig is a welding fixture designed and manufactured according to the coordinate points of the outer shape dimensions of the welded parts calibrated during the design of the welded product. Welding jigs are common in the electronics industry and are widely used in various PCB weldings (such as computer motherboards, graphics cards, etc.). In this industry, its main function is to position and fix the integrated circuit board, so as to facilitate the welding of components and wiring on the integrated circuit board.

[0003] In actual work, the structure and function of the welding jig of the existing technology are relatively perfect and can basically meet the daily use requirements, but there are still the following problems:

[0004] In the actual use process, the welding equipment can often only clamp and weld a specified number of circuit boards. Therefore, when the number of circuit boards to be welded increases, it can only be welded separately or the welding jig is replaced. Welding separately will lead to a decrease in welding efficiency, and replacing the welding jig will increase the cost.

[0005] Therefore, the utility model provides a circuit board welding jig. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Such asFigures 1-4 As shown in the figure, this embodiment provides a technical solution: a circuit board welding jig, including a fixing plate 1 and a placement plate 2. One side of the outer surface of the fixing plate 1 is fixedly connected with a mounting block 3. The inner wall of the mounting block 3 is threadedly connected with a threaded fixing rod 4. The top of the outer surface of the placement plate 2 is provided with a placement groove 5; an auxiliary disassembly and assembly structure 7 is arranged between the fixing plate 1 and the placement plate 2; one side of the outer surface of the placement plate 2 is provided with a splicing and limiting structure 6; the splicing and limiting structure 6 includes an L-shaped connecting rod 61 and a plurality of mounting plates 62. One end of the L-shaped connecting rod 61 is fixedly connected with one side of the outer surface of the placement plate 2, and the end of the L-shaped connecting rod 61 far from the placement plate 2 is fixedly connected with one side of the outer surface of one of the mounting plates 62.

[0028] By setting a rectangular clamping block 65 and a rectangular clamping frame 63, the mounting plate 62 can be disassembled and assembled, and thus the number of mounting plates 62 can be increased or decreased according to the number of circuit boards to be welded. Furthermore, different numbers of circuit boards can be clamped and welded without preparing multiple welding jigs, thereby reducing costs. At the same time, multiple circuit boards can be welded, thus improving the overall welding efficiency. By setting a rectangular clamping position groove 72 and a rectangular clamping position block 73, the fixing plate 1 and the placement plate 2 can be assisted in disassembly and assembly, and thus the placement plate 2 can be disassembled and assembled according to the actual usage situation, which is convenient for replacement and maintenance.

[0029] Furthermore, as Figure 2 shown: One side of the outer surface of the mounting plate 62 is fixedly connected with a rectangular clamping frame 63. The side of the outer surface of the mounting plate 62 opposite to the rectangular clamping frame 63 is fixedly connected with a connecting circular block 64. One side of the outer surface of the connecting circular block 64 is fixedly connected with a rectangular clamping block 65. The rectangular clamping frame 63 and the rectangular clamping block 65 located on two different mounting plates 62 are clamped and fixed. The inner wall of the rectangular clamping block 65 is provided with a first insertion hole 67. The two inner walls of the rectangular clamping frame 63 are provided with second insertion holes 66. A first threaded insertion rod 68 is inserted into the inner walls of the first insertion hole 67 and the second insertion hole 66. One end of the outer surface of the first threaded insertion rod 68 is threadedly connected with a first fixing nut 69. The inner wall of the mounting plate 62 is threadedly connected with a threaded rod 610. The bottom end of the outer surface of the threaded rod 610 is rotatably connected with a pressing plate 611. The top of the outer surface of the pressing plate 611 is fixedly connected with a limiting rod 612. The limiting rod 612 is slidably arranged on the inner wall of the mounting plate 62. Under the action of the rectangular clamping block 65 and the rectangular clamping frame 63, the mounting plate 62 can be assisted in splicing in cooperation with the first threaded insertion rod 68 and the first fixing nut 69. Furthermore, the splicing and fixing can be carried out according to the number of circuit boards to be welded actually required, and thus different numbers of circuit boards can be assisted in clamping, which is convenient for welding. Under the action of the threaded rod 610 and the pressing plate 611, the circuit board can be assisted in limiting, which is convenient for welding.

[0030] In the above solution, there is also a problem that the placement plate 2 is usually welded integrally with the operating table, resulting in the need to replace the entire placement plate 2 once it is damaged, increasing the use cost. For example, Figure 3 and Figure 4 As shown: In this solution, the auxiliary disassembly and assembly structure 7 includes a clamping groove 71, which is opened on the inner wall of the fixing plate 1. A rectangular clamping position groove 72 is opened on one side of the inner wall of the clamping groove 71. A rectangular clamping position block 73 is fixedly connected to one side of the outer surface of the placement plate 2. The inner wall of the rectangular clamping position groove 72 is detachably clamped with the outer surface of the rectangular clamping position block 73. A third insertion hole 74 is opened between the two sides of the inner wall of the fixing plate 1. A fourth insertion hole 75 is opened in the inner wall of the rectangular clamping position block 73. A second threaded insertion rod 76 is inserted into the inner walls of the third insertion hole 74 and the fourth insertion hole 75. A second fixing nut 77 is threadedly connected to one end of the outer surface of the second threaded insertion rod 76. Under the action of the rectangular clamping position block 73 and the rectangular clamping position groove 72, it can cooperate with the third insertion hole 74, the fourth insertion hole 75 and the second threaded insertion rod 76, so that the fixing plate 1 and the placement plate 2 can be disassembled, assembled and fixed, thereby facilitating the replacement and maintenance of the placement plate 2.

[0031] Working principle:

[0032] For example Figures 1-4 As shown:

[0033] When in use: Insert the rectangular clamping position block 73 into the inner wall of the rectangular clamping position groove 72, and then insert the second threaded insertion rod 76 into the inner walls of the third insertion hole 74 and the fourth insertion hole 75, and fix the second fixing nut 77 with the second threaded insertion rod 76;

[0034] Insert the rectangular block 65 into the inner wall of the rectangular frame 63, and then insert the first threaded insertion rod 68 into the inner walls of the first insertion hole 67 and the second insertion hole 66, and at the same time fix the first fixing nut 69 with the first threaded insertion rod 68;

[0035] At this time, rotate the threaded rod 610, so that the threaded rod 610 can drive the pressing plate 611 to move, and then can assist in limiting the circuit board inside the placement groove 5.
