Description

Technical Field

[0001] This utility model relates to the field of wave soldering fixture technology, specifically a fixture for wave soldering of electronic components. Background Technology

[0002] Wave soldering refers to the process of spraying molten solder into a designed solder wave using an electric or electromagnetic pump, or by injecting nitrogen into the solder bath. The printed circuit board (PCB) containing pre-loaded components passes through the solder wave to achieve mechanical and electrical connections between the component terminals or leads and the PCB pads. Wave soldering ovens are equipment used for wave soldering of electronic products, primarily for wave soldering circuit boards in electronic products.

[0003] When performing wave soldering on electronic components, a fixture is typically used to clamp and position them. If the clamping and positioning are not stable, the electronic components are prone to positional shifts during the wave soldering process. These shifts can lead to welding errors, resulting in welding failures or defective products, thus reducing the welding pass rate. Therefore, a fixture for wave soldering of electronic components is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a tooling for wave soldering of electronic components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for wave soldering of electronic components, comprising...

[0006] The base plate has a placement groove on its top and a through groove at the bottom of one end of the placement groove;

[0007] A limiting component is provided on the top of the base plate, and a fixing component for welding parts is provided on the top of the base plate outside the limiting component.

[0008] The limiting component includes several fixed posts, a limiting seat, and a first telescopic spring. The fixed posts are all threadedly connected to the top of the base plate. One end of the limiting seat is movably sleeved on the outside of the fixed posts. The outside of the first telescopic spring is movably sleeved on the outside of the fixed posts. One end of the first telescopic spring abuts against the top of the limiting seat. A positioning component is provided on the top of the base plate outside the limiting seat.

[0009] Preferably, the positioning component includes a triangular positioning post, which is fixedly connected to the top of the base plate. The outer side of the limiting seat has two V-shaped positioning grooves, and the triangular positioning post is engaged with the inside of one of the V-shaped positioning grooves.

[0010] Preferably, the aforementioned fixing assembly includes two first guide posts and two limiting posts. The two first guide posts are fixedly connected to both ends of the base plate. The two ends of the limiting posts are respectively movably sleeved on the outside of the two first guide posts on one side. The bottom of the limiting post is provided with several slots. A fixing plate is installed on the top of the limiting post. Several fixing rods are movably passed through the fixing plate. A third telescopic spring is movably sleeved on the outside of the fixing rods. The several fixing rods abut against the top of the limiting post. The top of both ends of the base plate are provided with mounting components.

[0011] Preferably, one end of the third telescopic spring is fixedly connected to the bottom of the fixing plate, and the other end of the third telescopic spring is fixedly connected to the outside of the fixing rod.

[0012] Preferably, the top of the base plate is fixedly connected to two second guide posts outside the limiting posts, and the bottom of the fixing plate is provided with two positioning holes on both sides, with the second guide posts matching the positioning holes.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0016] This invention places the components to be welded inside a placement groove, with the component leads passing through the groove. One end of a rotating limiting seat moves to the top of the placement groove, thus limiting one end of the component. A limiting post is then placed above the other end of the component. A fixing rod abuts against the top of the limiting post. Moving the fixing plate downwards compresses the third telescopic spring, causing the fixing rod to press tightly against the top of the limiting post. Simultaneously, both ends of the fixing plate abut against the top of the buckle and push it to rotate. At this point, the second telescopic spring is compressed. When the fixing plate abuts against the top of the fixing seat, the second telescopic spring causes the buckle to reset, locking it into the top of the fixing plate. This completes the fixing of multiple components, ensuring the stability of component fixing, improving the welding pass rate, and enabling the processing of multiple components at once, thus improving component processing efficiency.

Example

[0026] Please see Figure 1-5 This utility model provides a technical solution: a tooling for wave soldering of components, including a base plate 1, a placement groove 7 is provided on the top of the base plate 1, and a through groove 8 is provided at the bottom of one end of the placement groove 7; a limiting component is provided on the top of the base plate 1, and a fixing component for welding parts is provided on the top of the base plate 1 outside the limiting component.

[0027] By setting a limiting component, one end of the component can be limited, which is simple and quick. The limiting component includes several fixed posts 2, a limiting seat 3, and a first telescopic spring 4. The fixed posts 2 are all connected to the top of the base plate 1 by threads. One end of the limiting seat 3 is movably sleeved on the outside of the fixed posts 2. The outside of the first telescopic spring 4 is movably sleeved on the outside of the fixed posts 2. One end of the first telescopic spring 4 abuts against the top of the limiting seat 3. The top of the base plate 1 is provided with a positioning component on the outside of the limiting seat 3. By placing the component to be welded inside the placement groove 7, with the lead of the component passing through the inside of the through groove 8, and then pushing the limiting seat 3 to rotate around the fixed posts 2 as the center, one end of the limiting seat 3 moves to the top of the placement groove 7, thus completing the limiting of the component.

[0028] To ensure the accuracy of the limiting position of the limiting seat 3, the positioning component includes a triangular positioning post 5, which is fixedly connected to the top of the base plate 1. Two V-shaped positioning grooves 6 are opened on the outer side of the limiting seat 3, and the triangular positioning post 5 is engaged inside one of the V-shaped positioning grooves 6. When the limiting seat 3 rotates, one V-shaped positioning groove 6 disengages from the outer side of the triangular positioning post 5. When the other V-shaped positioning groove 6 moves to the outer side of the triangular positioning post 5, it can limit the position of the limiting seat 3 and ensure the accuracy of the rotation position of the limiting seat 3.

[0029] To limit the other end of the component, the fixing assembly includes two first guide posts 9 and two limiting posts 10. The two first guide posts 9 are fixedly connected to both ends of the base plate 1. The two ends of the limiting posts 10 are respectively movably sleeved on the outside of the two first guide posts 9 on one side. The bottom of the limiting posts 10 has several slots 11. The top of the limiting posts 10 is equipped with a fixing plate 17. Several fixing rods 18 movably pass through the fixing plate 17. The outside of the fixing rods 18 is movably sleeved with a third telescopic spring 19. One end of the third telescopic spring 19 is fixedly connected to the fixing plate 17. At the bottom, the other end of the third telescopic spring 19 is fixedly connected to the outside of the fixing rod 18. Several fixing rods 18 abut against the top of the limiting post 10, and the two ends of the limiting post 10 are fitted onto the outside of the first guide post 9. At this time, the limiting post 10 limits the other end of the component. At the same time, the slot 11 can limit the protruding position of the component. The fixing rod 18 abuts against the top of the limiting post 10. When the fixing plate 17 moves downward, the third telescopic spring 19 is compressed, so that the fixing rod 18 is tightly attached to the top of the limiting post 10. Mounting components are provided at the top of both ends of the base plate 1.

[0030] Two second guide posts 12 are fixedly connected to the top of the base plate 1 on the outside of the limiting post 10. Two positioning holes 20 are opened on both sides of the bottom of the fixing plate 17. The second guide posts 12 and the positioning holes 20 are matched with each other. By aligning the positioning holes 20 of the fixing plate 17 with the second guide posts 12, the second guide posts 12 pass through the interior of the positioning holes 20 to facilitate the installation and positioning of the fixing rod 18 and the limiting post 10.

[0031] To secure the components, the mounting assembly includes two mounting bases 13 and two clips 15. The two mounting bases 13 are fixedly connected to both ends of the base plate 1. Mounting grooves 14 are formed on the top of each mounting base 13. The clips 15 are rotatably connected to the inside of the mounting grooves 14 via shafts. A second telescopic spring 16 is installed at the bottom of the mounting grooves 14, with one end of the second telescopic spring 16 attached to the lower side of one side of the clip 15. The bottom ends of the fixing plate 17 abut against the tops of the two mounting bases 13, and the clips 15 are engaged with the top of the fixing plate 17. At both ends of the fixed plate 17, during the movement of the fixed plate 17, the two ends of the fixed plate 17 abut against the top of the buckle 15 and push it to rotate. At this time, the second telescopic spring 16 is compressed by force. When the fixed plate 17 abuts against the top of the fixed seat 13, the second telescopic spring 16 drives the buckle 15 to reset, so that the buckle 15 is engaged with the top of the fixed plate 17, thus completing the fixing of multiple components, ensuring the stability of component fixing, improving the welding qualification rate, and enabling the processing of multiple components at one time, thereby improving the efficiency of component processing.

[0032] Working principle or structural principle: When wave soldering of components is required, the components to be soldered are placed inside the placement groove 7, with the leads of the components passing through the inside of the through groove 8. Then, the limiting seat 3 is pushed to rotate around the fixed post 2 as the center. At the same time, one V-shaped positioning groove 6 disengages from the outside of the triangular positioning post 5. When the other V-shaped positioning groove 6 moves to the outside of the triangular positioning post 5, it can limit the position of the limiting seat 3. At this time, one end of the limiting seat 3 moves to the top of the placement groove 7, thereby limiting one end of the component.

[0033] Next, the two ends of the limiting post 10 are fitted onto the outside of the first guide post 9. At this time, the limiting post 10 limits the other end of the component, and the slot 11 limits the protruding position of the component. Then, the positioning hole 20 of the fixing plate 17 is aligned with the second guide post 12. The second guide post 12 passes through the inside of the positioning hole 20, and the fixing rod 18 abuts against the top of the limiting post 10. The fixing plate 17 is moved downward, and the third telescopic spring 19 is compressed, so that the fixing rod 18 is tightly attached to the top of the limiting post 10. At the same time, the two ends of the fixing plate 17 abut against the top of the buckle 15 and push it to rotate. At this time, the second telescopic spring 16 is compressed. When the fixing plate 17 abuts against the top of the fixing seat 13, the second telescopic spring 16 drives the buckle 15 to reset, so that the buckle 15 is engaged with the top of the fixing plate 17, thus completing the fixing of the position of the fixing plate 17 and completing the installation and fixing of the component.
