Description

Technical Field

[0001] The utility model relates to the technical field of electronic assembly, in particular to a simple tooling for placing tin rings. Background Technique

[0002] The chemical symbol of tin is Sn, which is a metallic element and an inorganic substance. Ordinary white tin is a low-melting metal with a silver-white luster. It is divalent or tetravalent in compounds and will not be oxidized by air at room temperature. In nature, it mainly exists in the form of dioxide (cassiterite) and various sulfides (such as cylindrite). Based on the laser welding technology of pins, small-sized tin rings need to be placed at the root of the pins in advance, and then the laser welding robot melts the tin rings through laser to complete the pin welding. Currently, there are two ways to place tin rings: manual operation. Assuming it takes 4 seconds to place one tin ring, and there are 128 pins on the entire PCB board, it takes nearly 9 minutes. Therefore, this method is time-consuming and laborious, and it is easy to miss placing. Placing tin rings by a robot can achieve automation, but it is also time-consuming and laborious, and increases the welding cost. Therefore, it is very necessary to design a simple tooling for placing tin rings with strong practicability and convenient, time-saving and labor-saving placement. Content of the Utility Model

[0003] The purpose of the utility model is to provide a simple tooling for placing tin rings to solve the problems raised in the above background technique.

The upper end of the workbench is symmetrically and fixedly installed with lifting rods, and the lifting rods are symmetrically and movably installed in the lifting plate. One end of the workbench is movably installed with a first threaded rod, and the first threaded rod is threadedly connected in the lifting plate. The lower end of the first threaded rod is fixedly installed with a dial, and one end of the dial extends out of the side wall of the workbench. A first placement groove is penetrated and opened in the lifting plate. A docking plate is arranged in the first placement groove. The docking plate is evenly provided with docking ports, and the docking ports are frustum-shaped. The diameter of the lower end of the docking port is slightly larger than the diameter of the tin ring. The docking plate is symmetrically and fixedly installed with clamping blocks, and the first placement groove is symmetrically provided with clamping grooves, and the clamping blocks are movably installed in the corresponding clamping grooves. One end of the baffle is movably installed at the lower end of the lifting plate. One end of the baffle is symmetrically provided with a hand-pulling groove.

Symmetrically opened at one end of the baffle 12 are hand-drawing grooves 13. The upper end surface of the baffle 12 is in contact with the lower end surface of the docking plate 8. Symmetrically fixed on the baffle 12 are sliding blocks 14, and symmetrically opened in the first placement groove 7 are sliding grooves 15. The sliding blocks 14 are movably installed in the corresponding sliding grooves 15. The positioning pins on the upper end of the PCB board 3 correspond one by one to the docking ports 9 on the docking plate 8. A placement plate 16 is provided on the lifting plate 2, and uniformly opened on the placement groove are leakage grooves 17. The width of the upper end of the leakage groove 17 is greater than the width of the lower end of the leakage groove 17. When the present utility model is in use, first, the tin rings can be placed in the leakage grooves 17. By shaking the placement plate 16, the tin rings can fall into the corresponding docking ports 9. Each docking port 9 can only accommodate one tin ring. As Figure 5 shown, it is the state of two tin rings placed in the docking port 9. The height of the tin ring is slightly lower than the height of the docking port 9, so that the docking port 9 can accommodate one and only one tin ring. The extra tin rings are dialed to the outside, and the tin rings are blocked by the baffle 12. After the tin rings are placed, by dialing the dial 6, the lifting plate 2 is lowered so that it is exactly located on the positioning pins on the upper end of the PCB board 3. The positioning pins on the upper end of the PCB board 3 correspond one by one to the docking ports 9 on the docking plate 8. By pulling the baffle 12 away through the hand-drawing groove 13, the tin rings fall onto the corresponding pins, and the tin rings are melted by laser through a laser welding robot to complete the pin welding;

[0021] Specifically, symmetrically fixed on the placement plate 16 are first connection blocks 18, and symmetrically fixed on the upper end of the lifting plate 2 are fixed seats 19. An activity groove 20 is opened in the middle of the fixed seat 19, and the placement plate 16 is movably installed in the corresponding activity groove 20. Through the activity groove 20, the first connection blocks 18 can be placed, which can facilitate the lapping of the placement plate 16;

[0022] Specifically, vertical plates 21 are symmetrically and fixedly installed at the upper end of the workbench 1. A second threaded rod 22 is threadedly connected inside the vertical plate 21. A clamping plate 23 is fixedly installed at adjacent ends of the second threaded rod 22. The PCB board 3 is clamped between the clamping plates 23. A spring 24 is fixedly installed between the clamping plate 23 and the vertical plate 21. A turning handle 25 is fixedly installed at the far end of the second threaded rod 22. By rotating the turning handle 25, the clamping plate 23 can clamp and fix the PCB board 3 to make it stable.

[0023] Specifically, a second connecting block 26 is fixedly installed at the lower end of the first connecting block 18. A limiting groove 27 is formed in the moving groove 20. The second connecting block 26 is movably installed in the corresponding limiting groove 27. By the combined use of the second connecting block 26 and the limiting groove 27, the movement of the placing plate 16 can be limited, and at the same time, it can move along the limiting groove 27 to prevent it from shaking randomly;

[0024] Specifically, a positioning plate 28 is fixedly installed at the central position of the upper end of the workbench 1. A positioning groove 29 is formed at the lower end of the PCB board 3. The positioning plate 28 is movably installed in the corresponding positioning groove 29. By the combined use of the positioning plate 28 and the positioning groove 29, the PCB board 3 can be centered when being placed;

[0025] Specifically, a top plate 30 is fixedly installed at the upper end of the first threaded rod 5, and the top plate 30 is flush with the upper end of the lifting rod 4. The up and down displacement of the lifting plate 2 can be limited by the top plate 30.

[0026] Working principle: When the present utility model is in use, first, the tin ring can be placed in the leakage groove 17. By shaking the placing plate 16, the tin ring can fall into the corresponding docking port 9. The docking port 9 can only accommodate one tin ring. The first connecting block 18 can be placed through the moving groove 20, which is convenient for lapping with the placing plate 16. By the combined use of the second connecting block 26 and the limiting groove 27, the movement of the placing plate 16 can be limited, and at the same time, it can move along the limiting groove 27 to prevent it from shaking randomly, as Figure 5As shown, it is the state where two tin rings are placed in the docking port 9. The height of the tin ring is slightly lower than that of the docking port 9, which enables the docking port 9 to accommodate only one tin ring, and the extra tin rings are dialed to the outside and blocked by the baffle 12. After the tin rings are placed, the lifting plate 2 is lowered by dialing the dial 6 so that it is exactly located on the positioning pins at the upper end of the PCB board 3. By turning the handle 25, the clamping plate 23 can clamp and fix the PCB board 3 to make it stable. The elastic force of the spring 24 strengthens the anti-loosening property of the threaded connection. By using the positioning plate 28 and the positioning groove 29 in cooperation, the PCB board 3 can be centered when placed. The positioning pins at the upper end of the PCB board 3 correspond to the docking ports 9 on the docking board 8 one by one. By pulling the baffle 12 open through the hand-drawn groove 13, the tin rings fall onto the corresponding pins, and the tin rings are melted by laser through a laser welding robot to complete the pin welding. The docking board 8 can be conveniently replaced according to different tin ring specifications, making it more flexible to use.
