Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a patch-mount welding device for circuit board processing. Background Technology

[0002] In circuit board manufacturing, surface mount soldering is one of the key processes, and its quality directly affects the performance and reliability of the circuit board. During soldering, precise alignment and stable connection between components and the circuit board are crucial; any deviation or defect can lead to degraded electrical performance, abnormal signal transmission, or even circuit board failure. Therefore, ensuring that the circuit board is free from skewing, components are accurately positioned, and solder joints are of reliable quality during the soldering process is a core element in improving the overall performance and reliability of the circuit board.

[0003] During the soldering process, the circuit board is prone to tilting or displacement due to the pressure or mechanical vibration applied by the soldering head, resulting in inaccurate component placement or even damage to the circuit board.

[0004] Traditional fixing fixtures typically employ mechanical clamping or vacuum adsorption, but these methods cannot completely eliminate circuit board misalignment. Mechanical clamping may cause the circuit board to warp or even tilt during the clamping process, while vacuum adsorption is ineffective for circuit boards with uneven surfaces or through holes, making it difficult to achieve stable fixation.

[0005] In view of this, a surface mount soldering apparatus for circuit board processing is provided to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a patch-mount welding device for circuit board processing to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a surface mount welding device for circuit board processing, including a base plate, a support plate, and a welding robot. A rotatable bidirectional lead screw is provided on the top surface of the support plate. Two retaining blocks are threadedly connected to the outer wall of the bidirectional lead screw. The two retaining blocks are symmetrically arranged in the initial state. A square groove is formed on the top surface of the retaining block. A rotating shaft is fixedly installed inside the square groove. A rotatable fixing block is sleeved on the outer wall of the rotating shaft. A through groove is formed at the bottom of the fixing block. A straight groove is formed on the inner wall of the through groove. A movable drive rod is provided at the top of the inner wall of the straight groove in the initial state.

[0008] Furthermore, the specific number of straight slots is two, with the two straight slots located on both sides of the inner wall of the through groove, and the drive rod simultaneously located inside the two straight slots.

[0009] Furthermore, an electric telescopic rod is fixedly installed on the inner wall of the square groove, and the side of the electric telescopic rod closest to the fixed block is fixedly connected to the drive rod.

[0010] Furthermore, an anti-slip rubber pad is fixedly installed on the top of the outer wall of the fixing block near the bearing plate.

[0011] Furthermore, three mounting slots are provided on the top surface of the bearing plate. The bidirectional lead screw is rotatably mounted on the inner wall of the mounting slot in the middle position, and guide rods are fixedly mounted on the inner walls of the two mounting slots at the edge positions.

[0012] Furthermore, the two retaining blocks are threadedly connected to the outer wall of the bidirectional lead screw and can also be slidably sleeved on the outer wall of the two mounting slots.

[0013] Furthermore, a rocker arm in an overall "L" shape is fixedly connected to one side of the bidirectional lead screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting fixed blocks and retaining blocks, the device can position and clamp the circuit through the rotating shaft. The two fixed blocks can simultaneously fix the top of both sides of the circuit board, so that the circuit board can be stably placed in the middle of the top surface of the support plate during the soldering process. This prevents the circuit board from easily shifting or warping during subsequent soldering, ensuring the quality of the soldering and improving the practicality of the device.

[0021] 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.

[0022] Example 1

[0023] See Figure 1-4 A surface mount welding device for circuit board processing includes a base plate 1, a support plate 2, and a welding robot 4. A rotatable bidirectional lead screw 8 is provided on the top surface of the support plate 2. Two retaining blocks 5 are threadedly connected to the outer wall of the bidirectional lead screw 8. The two retaining blocks 5 are symmetrically arranged in the initial state. A square groove 12 is opened on the top surface of the retaining block 5. A rotating shaft 15 is fixedly installed inside the square groove 12. A rotatable fixing block 11 is sleeved on the outer wall of the rotating shaft 15. A through groove 13 is opened at the bottom of the fixing block 11. A straight groove 14 is opened on the inner wall of the through groove 13. A movable drive rod 16 is provided on the top of the inner wall of the straight groove 14 in the initial state.

[0024] Furthermore, there are two straight slots 14. The two straight slots 14 are located on both sides of the inner wall of the through groove 13. The drive rod 16 is located inside the two straight slots 14. By setting the drive rod 16 to be inside the two straight slots 14 at the same time, when the drive rod 16 drives the fixed block 11 to rotate through the straight slots 14, the two straight slots 14 can share the traction force provided by the drive rod 16. This not only prevents damage to the internal shape of the straight slots 14, but also provides balance for the traction force.

[0025] Furthermore, an electric telescopic rod 10 is fixedly installed on the inner wall of the square groove 12. The side of the electric telescopic rod 10 closest to the fixed block 11 is fixedly connected to the drive rod 16. By setting the electric telescopic rod 10, the user can drive the drive rod 16 to move through the electric telescopic rod 10, thereby making it easier to drive the rotation of the fixed block 11.

[0026] In addition, an anti-slip rubber pad is fixedly installed on the top of the outer wall of the fixed block 11 near the bearing plate 2, and a rocker arm 9 in the shape of an "L" is fixedly connected to one side of the bidirectional screw 8.

[0027] By fixing an anti-slip rubber pad to the top of the outer wall of the fixing block 11 near the bearing plate 2, the fixing block 11 will not easily damage the circuit board after rotating and pressing it down, and at the same time, it can further prevent the circuit board from shifting, making the welding work of the device more stable.

[0028] By setting an "L"-shaped joystick 9, users can more easily rotate the bidirectional lead screw 8.

[0029] It should be noted that three mounting slots 6 are provided on the top surface of the bearing plate 2. The bidirectional lead screw 8 is rotatably installed on the inner wall of the mounting slot 6 in the middle position. Guide round rods 7 are fixedly installed on the inner walls of the two mounting slots 6 at the edge positions. The two retaining blocks 5 are threadedly connected to the outer wall of the bidirectional lead screw 8 and can also slide on the outer walls of the two mounting slots 6. A support block 3 is fixedly installed on one side of the bearing plate 2, and the welding robot 4 is fixedly installed on the top of the support block 3.

[0030] By setting two retaining blocks 5 that are threadedly connected to the outer wall of the bidirectional lead screw 8 and can also be slidably sleeved on the outer wall of the two mounting slots 6, the retaining blocks 5 can be driven by the bidirectional lead screw 8 and limited by the two mounting slots 6, making the retaining blocks 5 more stable during movement.

[0031] In practice, conventional welding equipment can keep the circuit board stable by simply clamping it during the welding process. However, the circuit board may warp or tilt due to the clamping force, which will affect the welding work of the subsequent welding mechanism.

[0032] In this application, when the user needs to fix the circuit board, he can directly rotate the rocker arm 9. The rocker arm 9 is fixedly connected to the bidirectional lead screw 8. Therefore, after the rocker arm 9 rotates, the bidirectional lead screw 8 will also rotate synchronously. The two retaining blocks 5 are symmetrically threaded on the outer wall of the bidirectional lead screw 8. Therefore, after the bidirectional lead screw 8 rotates, the two retaining blocks 5 will move closer or further away synchronously, thereby completing the clamping and positioning of the circuit board.

[0033] Simultaneously, after initial fixation, the user can drive the two electric telescopic rods 10 to move the drive rod 16 away from the circuit board. After being moved, the drive rod 16 will move inside the straight groove 14. The fixing block 11 is rotatably sleeved on the outer wall of the rotating shaft 15 and cannot move with the drive rod 16. Therefore, the movement of the drive rod 16 inside the straight groove 14 will synchronously drive the fixing block 11 to rotate, so that the fixing block 11 directly abuts against the top of the circuit board, preventing the top of the circuit board from warping. This allows the welding robot 4 to complete the subsequent welding work quickly and smoothly.

[0034] By setting the fixing block 11 and the retaining block 5, the device can complete the positioning and clamping of the circuit through the rotating shaft 15. The two fixing blocks 11 can simultaneously fix the top of both sides of the circuit board, so that the circuit board can be stably placed in the middle of the top surface of the support plate 2 during the welding process. It will not easily shift or warp during subsequent welding work, thus ensuring the welding quality and improving the practicality of the device.

[0035] Working principle: In conventional welding equipment, although the circuit board can be kept stable by simple clamping during the welding process, the circuit board may warp or tilt due to the clamping force, which will affect the welding work of the subsequent welding mechanism.

[0036] In this application, when the user needs to fix the circuit board, he can directly rotate the rocker arm 9. The rocker arm 9 is fixedly connected to the bidirectional lead screw 8. Therefore, after the rocker arm 9 rotates, the bidirectional lead screw 8 will also rotate synchronously. The two retaining blocks 5 are symmetrically threaded on the outer wall of the bidirectional lead screw 8. Therefore, after the bidirectional lead screw 8 rotates, the two retaining blocks 5 will move closer or further away synchronously, thereby completing the clamping and positioning of the circuit board.

[0037] Simultaneously, after initial fixation, the user can drive the two electric telescopic rods 10 to move the drive rod 16 away from the circuit board. After being moved, the drive rod 16 will move inside the straight groove 14. The fixing block 11 is rotatably sleeved on the outer wall of the rotating shaft 15 and cannot move with the drive rod 16. Therefore, the movement of the drive rod 16 inside the straight groove 14 will synchronously drive the fixing block 11 to rotate, so that the fixing block 11 directly abuts against the top of the circuit board, preventing the top of the circuit board from warping. This allows the welding robot 4 to complete the subsequent welding work quickly and smoothly.

[0038] By setting the fixing block 11 and the retaining block 5, the device can complete the positioning and clamping of the circuit through the rotating shaft 15. The two fixing blocks 11 can simultaneously fix the top of both sides of the circuit board, so that the circuit board can be stably placed in the middle of the top surface of the support plate 2 during the welding process. It will not easily shift or warp during subsequent welding work, thus ensuring the welding quality and improving the practicality of the device.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
