Description

Technical Field

[0001] This utility model is a circuit board welding fixture, belonging to the field of circuit boards. Background Technology

[0002] With the advancement of technology, various electronic products have become an indispensable part of people's lives. Among them, circuit boards are an important component of electronic products. The number and types of components that need to be soldered on circuit boards are numerous and diverse. How to ensure the soldering quality of display circuit boards during the manufacturing process has become an urgent problem to be solved.

[0003] During the circuit board manufacturing process, when soldering electronic components onto the circuit board, the operator needs to hold a soldering iron in one hand and solder wire in the other. First, the electronic component is inserted into the hole in the circuit board, and then the circuit board is flipped over for soldering and fixing. However, currently, in many cases, the circuit board is simply placed on the workbench for soldering. Due to the lack of fixation, soldering errors are prone to occur, easily damaging the circuit board and presenting significant defects. Therefore, this utility model proposes a flip-and-fixture circuit board soldering fixture. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a circuit board welding fixture.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A circuit board soldering fixture includes a base plate, a fixed box suspended above the top of the base plate, a clamping assembly for clamping circuit boards inside the fixed box, and openings at both the top and bottom of the fixed box. Two vertical plates are fixedly mounted on the top of the base plate, and the vertical plates and the fixed box are rotatably connected by a bearing. A supporting rod is connected between the bearings. A flip positioning assembly is provided between the base plate and the fixed box. The flip positioning assembly includes a fixing member fixed to the base plate and two positioning members mounted on the fixed box. The fixing member includes a secondary vertical plate with a threaded hole at its top. The positioning members include a tube fixed to the outer wall of the fixed box, with a plate inserted inside the tube. Corresponding threaded holes are provided on the plate and the tube.

[0007] Furthermore, the clamping assembly includes two L-shaped support plates disposed inside the fixing box, and a lead screw is inserted inside the fixing box. The lead screw is a double-axis lead screw, and the L-shaped support plates are threaded onto the lead screw.

[0008] Furthermore, a manual turntable is provided at one end of the lead screw, and a bearing is fitted at the other end of the lead screw. The bearing is fixed on the outer wall of the fixed box, and a traction rod that slides through the L-shaped support plate is fixed inside the fixed box.

[0009] Furthermore, the clamping assembly also includes two fixing plates fixed to the fixing box, with a pressure plate slidably disposed between the fixing plates, and a mounting plate fixed on one of the fixing plates and the outer wall of the fixing box.

[0010] Furthermore, a rotating auxiliary lead screw is fixed between the plates, and a threaded block sleeved on the auxiliary lead screw is fixed on the lower pressure plate.

[0011] Furthermore, a secondary manual turntable is provided at the top of the secondary lead screw, and a bearing three is sleeved on the other end of the secondary lead screw, with the bearing three fixed to the bottom end of the setting plate below.

[0012] Furthermore, a traction groove is provided on the outer wall of the fixing plate and the fixing box for the threaded block to pass through, and a smoothing groove is provided on the other fixing plate and the inner wall of the fixing box. A smoothing slider is fixed on the lower pressure plate and is slidably disposed inside the smoothing groove.

[0013] Furthermore, the circuit board has openings, and electrode posts are movably installed inside the openings. Electronic components are mounted on the electrode posts, and the lower pressure plate corresponds to the electronic components.

[0014] The beneficial effects of this utility model are:

[0015] The circuit board is fixed in the fixed box by the clamping assembly, so the top surface of the circuit board can be processed. This ensures that the circuit board is in a stable clamping state during processing, which can guarantee the subsequent processing of the circuit board.

[0016] When processing is required on the bottom surface of the circuit board, the operator can manually rotate the fixing box so that one of its positioning parts aligns with the fixing part, indicating that the front of the circuit board is being processed. When the other positioning part aligns with the fixing part, it means that the bottom surface of the circuit board has been flipped upwards, and the circuit board is now being processed with its bottom surface facing upwards. The insert plate can be extended or shortened within the insert sleeve. When the insert plate is shortened, it means that the insert plate has been flipped and is not obstructed by the secondary vertical plate. When it is flipped 180 degrees, the other positioning part aligns with the fixing part, and the insert plate of the other positioning part extends within the insert sleeve. Finally, after the insert plate is extended, one of the threaded holes on its insert plate aligns with the threaded hole one on the secondary vertical plate, and is inserted to fix the fixing box and the secondary vertical plate. This means that the fixing box is now fixedly suspended above the top of the base plate, facilitating subsequent processing of the circuit board.

[0017] This utility model has a simple design and can fix the circuit board after it is flipped 180 degrees, ensuring a stable processing environment on both sides of the circuit board. It can also effectively clamp the circuit board to ensure stability during processing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a circuit board welding fixture, including a base plate 1, a fixed box 2 suspended above the top of the base plate 1, a clamping assembly for clamping circuit boards 3 inside the fixed box 2, the top and bottom of the fixed box 2 being open, two vertical plates 4 fixedly mounted on the top of the base plate 1, the vertical plates and the fixed box 2 being rotatably connected by bearings 5, a supporting rod 6 connecting the bearings 5, a flip positioning assembly between the base plate 1 and the fixed box 2, the flip positioning assembly including a fixing member fixed on the base plate 1, and two positioning members mounted on the fixed box 2, the fixing member including a secondary vertical plate 7, the top of the secondary vertical plate 7 having a threaded hole 8, the positioning member including an insert 9 fixed on the outer wall of the fixed box 2, an insert plate 10 inserted into the insert 9, and corresponding threaded holes 11 on the insert plate 10 and the insert 9.

[0026] See Figure 3 The clamping assembly includes two L-shaped support plates 12 disposed inside the fixed box 2. A lead screw 13, which is a double-axis lead screw, is inserted into the fixed box 2. The L-shaped support plates 12 are threaded onto the lead screw 13. A manual turntable 14 is provided at one end of the lead screw 13, and a bearing 2 is sleeved at the other end of the lead screw 13. The bearing 2 is fixed to the outer wall of the fixed box 2. A traction rod that slides through the L-shaped support plates 12 is fixed inside the fixed box 2. Manually rotating the manual turntable 14 causes the lead screw 13 to rotate, thereby causing the two L-shaped support plates 12 to move away from or towards each other, ultimately clamping the circuit boards supported on the two L-shaped support plates 12 to ensure the stability of the circuit board processing.

[0027] See Figure 1 and Figure 4 The clamping assembly also includes two fixing plates 15 fixed on the fixing box 2. A lower pressure plate 16 is slidably arranged between the fixing plates 15. A setting plate 17 is fixed on one of the fixing plates 15 and the outer wall of the fixing box 2. A secondary lead screw 18 is fixedly arranged between the setting plates 17. A threaded block 19 is fixed on the lower pressure plate 16 and sleeved on the secondary lead screw 18. A secondary manual turntable 20 is set at the top of the secondary lead screw 18. A bearing 3 is sleeved on the other end of the secondary lead screw 18. The bearing 3 is fixed at the bottom end of the setting plate 17 below. The bearing design ensures the stability of the corresponding component rotation. Manually rotating the secondary manual turntable 20 drives the secondary lead screw 18 to rotate, thus driving the threaded block 19 to rise and fall vertically on the secondary lead screw 18, and finally driving the connected lower pressure plate 16 to press down the electronic component 23.

[0028] See Figure 3-4The outer walls of the fixed plate 15 and the fixed box 2 are provided with traction grooves 24 for threaded blocks 19 to pass through. The other fixed plate 15 and the inner wall of the fixed box 2 are provided with smoothing grooves 25. The lower pressure plate 16 is fixed with a smoothing slider 26 that slides inside the smoothing groove 25. The circuit board 3 has an opening 21. An electrode post 22 is movably installed inside the opening 21. An electronic component 23 is set on the electrode post 22. The lower pressure plate 16 corresponds to the electronic component 23. The smoothing slider 26 is in the smoothing groove 25 to ensure that the lower pressure plate 16 can rise and fall vertically and to ensure that the rise and fall of the lower pressure plate 16 can be more stable. After the circuit board 3 is fixed, the electronic component is installed on the circuit board. After the electrode post is installed inside the opening, the lower pressure plate 16 presses down on the electronic component. This ensures that the electrode post will not separate in the opening and the electronic component will not detach when the circuit board is flipped. After rotating 180 degrees, the bottom surface of the circuit board faces upward, so that the electrode post is exposed on the circuit board from the top, which is convenient for soldering.

[0029] In use, the circuit board is fixed to the fixing box 2 by the clamping assembly, thus allowing processing on the top surface of the circuit board. This ensures the circuit board is stably clamped during processing, guaranteeing proper subsequent processing. When processing the bottom surface of the circuit board 3 is required, the operator can manually rotate the fixing box 2 so that one of the positioning pieces aligns with the fixing piece, indicating front-side processing of the circuit board. When the other positioning piece aligns with the fixing piece, the bottom surface of the circuit board is flipped upwards, completing the bottom-side-up processing. The insert plate 10 can extend or shorten within the insert cylinder 9. When the insert plate 10 shortens, it indicates that the insert plate 10 has flipped and is no longer obstructed by the secondary vertical plate 7. When the circuit is rotated 180 degrees, another positioning component aligns with the fixing component, and the insertion plate 10 of the other positioning component extends within the insertion cylinder 9. Finally, after the insertion plate 10 extends, one of its threaded holes aligns with the threaded hole 8 on the secondary vertical plate 7, allowing for insertion and fixing of the fixing box 2 and the secondary vertical plate 7. This indicates that the fixing box 2 is now fixedly suspended above the top of the base plate 1, facilitating subsequent processing of the circuit board. This invention features a simple design, enabling the fixing of the circuit board after rotation (180 degrees), ensuring a stable processing environment on both sides of the circuit board, and effectively clamping the circuit board to guarantee stability during processing. Figure 1 There is only one flip positioning component, but multiple flip positioning components can actually be set to ensure better suspension and fixation of the fixed box. The vertical plate 4, bearing 5, support rod 6, and fixed box 2 are connected as one unit to ensure that the fixed box 2 can rotate. It should be noted that the support rod 6 corresponds to the middle position of the side of the fixed box 2.

[0030] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
