Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture reflow structure. Background Technology

[0002] Welding fixtures are specialized tools used in welding processes to precisely position and fix workpieces. They are typically customized by professional manufacturers according to customer needs. Their core function is to constrain the position of the workpiece through mechanical structures, ensuring accurate workpiece coordinates and stable assembly during welding. They are particularly suitable for functional testing, RF calibration, and precision component assembly in electronic product PCBAs. They are often made of lightweight, high-strength metals such as aluminum and are precision-machined to meet the rigidity requirements of clamping while avoiding damage to the workpiece. Through the positioning function of the fixture, non-destructive, high-strength welding can be achieved, significantly improving production efficiency and product consistency. In automated welding production lines, welding fixtures are often used in conjunction with robots and vision systems to complete multi-station synchronous operations, reducing errors caused by human intervention. In addition, some fixtures integrate sensors or quick-change designs to adapt to the flexible production needs of products with different specifications. They are key auxiliary equipment for achieving precision and standardized welding in modern manufacturing.

[0003] However, in the existing technology, the welding fixture stops at the end of the conveyor belt and cannot be returned. It can only be transported and returned after the next fixture collides with it, which is a long cycle and has low working efficiency of JIG. Therefore, we need a welding fixture return structure.

[0014] In the scheme of this application:

[0015] 1. To address the problem of low reflow efficiency and increased costs in existing welding fixtures, this application proposes a dual-stabilization structure. This structure involves a cylinder driving a push rod, a moving plate, and a square column to move in tandem, with a support spring providing stable support. Simultaneously, a motor-driven screw causes a sliding sleeve to precisely move the push plate, thereby moving the welding fixture. This dual-stabilization structure ensures accurate reflow of the welding fixture, effectively improving the stability and efficiency of the reflow operation, shortening the reflow cycle, reducing operating costs, and achieving efficient and low-cost welding fixture reflow.

[0016] 2. To address the cumbersome disassembly and assembly issues during maintenance of existing recirculation structures, this application employs a multi-layered structure, including a locking block and a locking groove, a protrusion and a groove, and a bolt for through-hole fixation. This allows for quick disassembly of the mounting plate during maintenance by simply turning the bolts, initial fixation during installation via locking and spring return, and subsequent reinforcement with bolts. This convenient operation significantly improves disassembly and assembly efficiency and fixation effectiveness, ensuring the stable operation of the recirculation structure.

[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] This utility model embodiment provides a welding fixture reflow structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the system includes a conveyor frame 1, a fixed plate 2 fixedly connected to the top of the conveyor frame 1, a mounting plate 3 on the top of the fixed plate 2, a push-back assembly 4 on the top of the mounting plate 3, and a disassembly assembly 5 on one side of the mounting plate 3. The push-back assembly 4 includes a cylinder 401, which is located on the top of the mounting plate 3. A push rod 402 is located on one side of the cylinder 401, and a moving plate 403 is fixedly connected to one end of the push rod 402. A square sleeve 404 is fixedly connected to the top of the mounting plate 3, and a square column 405 is slidably connected inside the square sleeve 404. A support is hinged to the bottom of the square column 405. The support rod 406 has a support sleeve 407 slidably connected to its outer wall. A support spring 408 is fixedly connected inside the support sleeve 407. A connecting plate 409 is fixedly connected to the top of the moving plate 403. A motor 410 is installed on the top of the connecting plate 409. A screw 411 is fixedly connected to the output end of the motor 410 via a coupling. A sliding sleeve 412 is threadedly connected to the outer wall of the screw 411. A push plate 413 is fixedly connected to the bottom of the sliding sleeve 412. A cylindrical sleeve 414 is fixedly connected to the bottom of the connecting plate 409. A telescopic rod 415 is slidably connected to the inner wall of the cylindrical sleeve 414.

[0026] Furthermore, such as Figure 2 As shown, the motor 410 forms a movable structure with the screw 411 and the sliding sleeve 412. One end of the screw 411 is fixedly connected to the coupling of the motor 410, and the outer wall of the screw 411 is threadedly connected to the inner wall of the sliding sleeve 412. This allows the screw 411 to move when the motor 410 drives the screw 411 to rotate.

[0027] Furthermore, such as Figure 3 As shown, the support sleeve 407 forms a support structure with the support spring 408 and the support rod 406. One end of the support spring 408 is fixedly connected to the inside of the support sleeve 407, and the other end of the support spring 408 is fixedly connected to one end of the support rod 406. This allows the support spring 408 to support the support rod 406 with the support sleeve 407, thereby improving the support effect of the support sleeve 407 on the support rod 406.

[0028] Furthermore, such as Figure 2 As shown, the cylindrical sleeve 414 forms a limiting structure with the push plate 413 through the telescopic rod 415, and the outer wall of the telescopic rod 415 is slidably connected to the inner wall of the cylindrical sleeve 414, and one end of the telescopic rod 415 is fixedly connected to the top of the push plate 413, so that when the push plate 413 drives the telescopic rod 415 to move, the telescopic rod 415 can move along the inner wall of the cylindrical sleeve 414.

[0029] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the disassembly assembly 5 includes a limiting groove 501, which is located on the top of the fixing plate 2. A return spring 502 is fixedly connected to the inner wall of the limiting groove 501. A protrusion 503 is fixedly connected to one end of the return spring 502. A limiting block 504 is engaged with the inner wall of the limiting groove 501. A groove 505 is provided on the outer wall of the limiting block 504. A bolt 506 is provided on one side of the mounting plate 3.

[0030] Furthermore, such as Figure 5 and Figure 6 As shown, the mounting plate 3 forms a locking structure with the limiting block 504 and the limiting groove 501. The outer diameter of the limiting block 504 matches the inner diameter of the limiting groove 501, and the outer wall of the limiting block 504 fits against the inner wall of the limiting groove 501, so that the limiting block 504 can be locked in the limiting groove 501, which improves the connection effect between the mounting plate 3 and the fixing plate 2.

[0031] Furthermore, such as Figure 5 As shown, the limiting groove 501 forms a spring structure with the protrusion 503 through the return spring 502, and the return spring 502 is disposed between the limiting groove 501 and the protrusion 503. The two ends of the return spring 502 are fixedly connected to the limiting groove 501 and the protrusion 503 respectively, which allows the return spring 502 to push the protrusion 503 to move under the elastic action, thereby improving the support effect of the limiting groove 501 on the protrusion 503.

[0032] Furthermore, such as Figure 4 and Figure 6 As shown, the mounting plate 3 is connected to the fixing plate 2 by bolts 506 to form a detachable structure. One end of the bolts 506 passes through the mounting plate 3 and extends into the fixing plate 2 for connection. By turning the bolts 506, one end of the bolts 506 can be disengaged from the fixing plate 2, thereby detaching the mounting plate 3 from the fixing plate 2 and improving the ease of disassembly.

[0033] Working principle: During the reflow of the welding fixture, cylinder 401 is first activated, causing push rod 402 to move. Push rod 402 moves moving plate 403, which in turn moves square column 405 along the inner wall of square sleeve 404. Square column 405 moves support rod 406. At this time, support spring 408 supports support rod 406 with the support sleeve 407, improving the stability of moving plate 403. Moving to one side of the welding fixture, motor 410 is simultaneously activated, causing screw 411 to rotate on the inner wall of sliding sleeve 412. Sliding sleeve 412 moves along the outer wall of screw 411, causing sliding sleeve 412 to move push plate 413. Push plate 413 moves telescopic rod 415 along the inner wall of cylindrical sleeve 414, improving the stability of pushing plate 413. Push plate 413 moves to one side of the welding fixture. After moving to the side and rear, cylinder 401 is then activated to push the welding fixture to complete the reflow, effectively shortening the reflow cycle and saving costs. If maintenance of the reflow structure is required, bolt 506 can be directly tightened to disengage one end from the connection with the fixed plate 2, allowing the mounting plate 3 to disengage from the fixed plate 2. The mounting plate 3 can then be moved upwards to disengage the limiting block 504 from the limiting groove 501, completing disassembly. During installation, the limiting block 504 is then engaged in the limiting groove 501. During engagement, the limiting block 504 presses the protrusion 503 to move, causing the protrusion 503 to compress the return spring 502. When the protrusion moves into the groove 505, the return spring 502 loses pressure and rebounds, pushing the protrusion 503 into the groove 505, completing the initial fixation. Then, bolt 506 is tightened to allow one end to penetrate the mounting plate 3 and enter the fixed plate 2, completing the fixation and improving the fixation effect.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
