[0002] When soldering circuit boards, it is usually necessary to use a clamp to hold the circuit board to be soldered in order to facilitate the soldering operation.
[0003] Existing circuit board welding fixtures have some shortcomings. For example, the clamping force is not uniform enough, which can easily cause the circuit board to slip or shift during welding, affecting the welding accuracy. In addition, most existing fixtures can only clamp a single circuit board and cannot clamp multiple circuit boards at the same time. This requires frequent disassembly and reassembly of circuit boards during welding, thus affecting welding efficiency. Utility Model Content
[0004] To facilitate the batch fixing and soldering of circuit boards, this application provides a circuit board soldering fixture.
[0005] The circuit board welding fixture provided in this application adopts the following technical solution:

A plurality of partition plates are slidably connected to the top of the support, and a receiving space for placing the circuit board is formed between adjacent partition plates. Each of the partition plates has a through-hole with a first stud threaded into the top of the hole. The partition plates and side plates are provided with grooves for placing the two ends of the circuit board, and a clamping mechanism is provided in the groove.
[0007] By adopting the above technical solution, the movable partition plates can accommodate circuit boards of different widths. The space between these partition plates can accommodate circuit boards of different sizes as needed, achieving the fixation of circuit boards of different specifications, thereby improving the flexibility and applicability of the welding fixture. Grooves are provided on both the partition plates and side plates to accommodate the pre-fixation of circuit boards. A clamping mechanism is installed inside the grooves to further press and fix the circuit boards, ensuring their stability during welding, improving welding quality and production efficiency.
[0008] Optionally, a slide rail is fixedly connected to the top of the support, the slide rail passes through the partition plate, and both ends of the slide rail are fixedly connected to the inner walls of the side plates at both ends of the support.
[0009] By adopting the above technical solution, the slide rail plays a positioning and guiding role, thereby ensuring that the partition panel can only move along the length of the slide rail, improving the stability of the partition panel when sliding.
[0010] Optionally, the top wall of the slide rail is higher than the bottom wall of the groove.
[0011] By adopting the technical scheme, since the top wall of the slide rail is higher than the bottom wall of the groove, when the circuit board is placed in the groove, one end of the circuit board will abut against the side wall of the slide rail, thereby playing a positioning role and ensuring stable clamping of the circuit board in the groove.
[0012] Optionally, the slide rail is provided with clamping blocks on both sides, and the clamping blocks are arranged through the partition plate.
[0013] By adopting the technical scheme, stable placement of the partition plate on the slide rail is ensured, the partition plate is prevented from shaking or deviating during sliding, and the partition plate is prevented from being lifted upward, so that the partition plate can slide smoothly and stably on the slide rail, and the stability during use is improved.
[0014] Optionally, the top wall of the clamping block is lower than the bottom wall in the groove.
[0015] By adopting the technical scheme, the clamping block cannot be inserted into the groove to affect placement of the circuit board, and stable movement of the partition plate is achieved while ensuring that placement of the circuit board is not affected, thereby improving the stability during use.
[0016] Optionally, the pressing mechanism comprises a second threaded stud arranged through and threadedly connected to the top wall of the groove, and a pressing plate rotationally connected to one end of the second threaded stud, and the pressing plate is arranged in the groove.
[0017] By adopting the technical scheme, rotation of the second threaded stud can realize lifting of the pressing plate, thereby effectively fixing circuit boards of different thicknesses and improving the flexibility during use.
[0018] Optionally, a guide column is fixedly connected to the top of the pressing plate, and the guide column is arranged through the top wall of the groove.
[0019] By adopting the technical scheme, the guide column plays a positioning and guiding role, so that the pressing plate cannot rotate around the second threaded stud when the pressing plate is lifted or lowered by rotating the second threaded stud, thereby ensuring that the pressing plate is lifted or lowered along the length direction of the second threaded stud and ensuring the stability during operation of the product.
[0020] Optionally, the inner wall of the groove and the bottom wall of the pressing plate are both provided with protective pads.
[0021] By adopting the technical scheme, when the circuit board is clamped and fixed, the inner wall of the groove and the bottom wall of the pressing plate will be pressed against the circuit board, and the protective pads can effectively prevent the circuit board from being damaged due to excessive pressing force of the pressing plate and the inner wall of the groove, thereby ensuring the safety during use.
[0022] Optionally, an inclined groove is arranged on the side of the support away from the first threaded stud.
[0023] By adopting the technical scheme, the inclined groove at the bottom of the support forms a space for placing hands, thereby expanding the operation space of the user during welding, facilitating the user to perform welding, element placement and other operations, and improving the convenience of use.
[0024] To sum up, the present application has the following beneficial effects:
[0025] 1. By setting the first stud, slide rail and partition plate, the user can fix circuit boards of different widths by sliding the partition plate and tightening the first stud, improving the convenience and flexibility of use.
[0026] 2. By setting the second stud, guide column and pressing plate, the user only needs to rotate the second stud to achieve the pressing and fixing of circuit boards of different thicknesses, thereby ensuring the stability of the circuit board during welding.
[0027] 3. By setting the protective pad, the pressing plate and the partition plate can effectively buffer when pressing and fixing the circuit board, ensuring that the circuit board is not easily damaged due to excessive pressing force during fixing, thereby ensuring the stability of use.

DETAILED DESCRIPTION
[0032] The following will be described in detail in combination with the accompanying Figures 1-3 The present application will be further described in detail.
[0033] An embodiment of the present application discloses a circuit board welding jig. Referring to Figure 1The circuit board welding jig comprises a support 1, side plates 2 mounted on both ends of the top of the support 1, and supporting legs 3 fixed on both sides of the support 1, a plurality of partition plates 11 are arranged between the side plates 2, and a space for placing the circuit board is formed between the adjacent side plates 2 and the partition plates 11. When welding, the circuit board is placed between the partition plates 11 and the side plates 2, so that batch placement and welding of the circuit board are realized.
[0034] With reference to Figure 1 A plurality of partition plates 11 are slidingly connected to the top of the support 1, the top of the support 1 is fixedly connected with sliding rails 12, the two ends of the sliding rails 12 are fixedly connected with the side plates 2 at both ends of the support 1, recesses 113 for placing the circuit board are formed in the partition plates 11 and the side plates 2, and a pressing mechanism 4 is arranged in the recesses 113. The partition plates 11 cooperate with the sliding rails 12, so that the partition plates 11 can slide along the length direction of the sliding rails 12 on the top of the support 1. When in use, the partition plates 11 can be moved to fix circuit boards of different sizes, so that the flexibility and applicability are improved. The pressing mechanism 4 can further press and fix the circuit board, is suitable for circuit boards of different thicknesses, ensures the stability of the circuit board during welding, and improves the welding quality and production efficiency.
[0035] With reference to Figure 1 , Figure 2 The partition plates 11 are provided with screw holes 111 penetrating in the thickness direction, and first studs 112 are threadedly connected in the screw holes 111. After the partition plates 11 are moved to adapt to circuit boards of different sizes, the first studs 112 are rotated, so that one end of the first studs 112 abuts against the top wall of the support 1. The partition plates 11 are fixed by the friction between the first studs 112 and the support 1, so that the partition plates 11 do not move during welding, and the stability during welding is ensured.
[0036] With reference to Figure 1 , Figure 3 The top wall of the sliding rail 12 is higher than the bottom wall in the recess 113. The sliding rail 12 can be transversely arranged in the recess 113. When the circuit board is placed in the recess 113, one end of the circuit board abuts against the side wall of the sliding rail 12 to play a positioning role, so that the circuit board is fixed, and the stable clamping of the circuit board in the recess 113 is ensured.
[0037] With reference to Figure 1 , Figure 3 The sliding rail 12 is provided with clamping blocks 121 penetrating the partition plates 11. The clamping blocks 121 make the partition plates 11 not easy to be separated from the sliding rail 12, ensure the stable placement of the partition plates 11 on the sliding rail 12, and make the partition plates 11 not easy to shake during sliding, so that the stability during use is improved.
[0038] With reference to Figure 1 , Figure 3The top wall of the engaging block 121 is lower than the bottom wall of the groove 113. While achieving stable movement of the partition plate 11 along the length direction of the slide rail 12, the engaging block 121 does not intrude into the interior of the groove 113, thereby ensuring the placement of the circuit board in the groove 113 is not affected, and improving the stability of use.
[0039] With reference to Figure 1 , Figure 3 The pressing mechanism 4 comprises a pressing plate 42 arranged in the interior of the groove 113 and a second stud 41 penetrating and threadedly connected to the top wall of the groove 113, and the second stud 41 is rotationally connected to the pressing plate 42 near one end of the groove 113. When pressing and fixing circuit boards of different thicknesses, the circuit board is placed in the groove 113, the second stud 41 is rotated, the second stud 41 drives the pressing plate 42 to descend, thereby realizing the pressing operation on the circuit board, and thereby realizing the fixing of circuit boards of different thicknesses, and improving the flexibility of use.
[0040] With reference to Figure 1 , Figure 3 The top of the pressing plate 42 is fixedly connected with a guide column 43 penetrating the top wall of the groove 113. When the pressing operation is performed by rotating the second stud 41, the pressing plate 42 does not rotate around the second stud 41, thereby ensuring that the pressing plate 42 intelligently moves along the length direction of the second stud 41, and guaranteeing the stability of the pressing operation.
[0041] With reference to Figure 1 , Figure 3 The inner wall of the groove 113 and the bottom wall of the pressing plate 42 are both provided with a protective pad 5 made of silica gel. When the circuit board is clamped and fixed, the inner wall of the groove 113 and the bottom wall of the pressing plate 42 will both extrude the circuit board, the protective pad 5 made of silica gel has good elasticity and can effectively buffer, so that during the extrusion and fixing process, the pressing plate 42 and the inner wall of the groove 113 will not cause damage to the circuit board due to excessive extrusion, thereby guaranteeing the safety during use.
[0042] With reference to Figure 1 , Figure 2 The support 1 is provided with an inclined groove 13 away from the side of the first stud 112. When the welding jig is placed on the desktop, the inclined groove 13 and the desktop form a space for placing a hand, thereby effectively expanding the operation space of the user, facilitating the user to perform welding, placing components and other operations, and improving the convenience of use.
[0043] The implementation principle of the circuit board welding jig according to the embodiment of the application is as follows: when the circuit board needs to be fixed, the circuit board is placed into the groove 113, the partition plate 11 is moved to match the size of the circuit board, the first stud 112 is rotated to make the partition plate 11 no longer slide, the second stud 41 is rotated to make the pressing plate 42 press downward, and the circuit board is fixed in the groove 113. At this time, the fixing of the circuit board is completed, the circuit board is not easy to move during welding operation, and multiple circuit boards can be fixed, thereby effectively improving the production efficiency.
[0044] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
