Description

Technical Field

[0001] This invention relates to the field of plasma welding technology, and in particular to a plasma welding apparatus for the production of semiconductor photosensitive elements. Background Technology

[0002] Existing plasma welding of semiconductor photosensitive components mostly involves generating a high-temperature arc with a plasma welding torch and connecting the component pins to the parts under inert gas protection. This requires manual or simple mechanism to fix the workpiece and relies on preset parameters to complete the welding operation.

[0003] The existing technology has significant drawbacks. First, the linkage between workpiece positioning and welding is poor. After the photosensitive element pins are assembled with the welding parts, the lack of a precise alignment structure often leads to welding position misalignment, affecting welding accuracy. Second, the start / stop and position adjustment of the welding parts are separate, requiring separate operation of the control button and adjustment of the welding torch position, which can easily cause operation delays and reduce welding efficiency. Third, the stabilization mechanism is missing or incomplete, making the workpiece susceptible to displacement due to external forces during welding, and the welding torch lacks effective storage and protection after welding, making it prone to damage due to accidental contact. Fourth, the operation safety and convenience are insufficient. Some devices require operators to approach the welding area for adjustment, posing safety hazards. In addition, the overall structure adjustment steps are cumbersome and not conducive to mass production.

[0004] Based on this, a plasma welding apparatus for the production of semiconductor photosensitive elements is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a plasma welding apparatus for the production of semiconductor photosensitive elements in order to solve the above-mentioned problems.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-5 The present invention provides a technical solution:

[0027] A plasma welding apparatus for producing semiconductor photosensitive elements includes a base 1, a fixing frame 4 connected to the upper end of the base 1, a docking block 5 connected to the fixing frame 4, and a welding groove 31 formed on the docking block 5. Before welding, the photosensitive element to be welded needs to be placed in the welding groove 31. A deflection block 8 is rotatably connected to the upper end of the base 1, and a clamping sleeve 29 is connected to one side of the deflection block 8. The part to be welded to the photosensitive element needs to be fixed in the clamping sleeve 29 beforehand. The clamping sleeve 29 is a round tube with an opening on one side and is divided into upper and lower sections. The welding position is located between the upper and lower sections, which is where the welding hole 18 is opened. During initial clamping, the part can be well fixed. During welding, the high temperature can melt the part at this point, causing the part to adhere to the pin of the photosensitive element on one side. Thus, after welding, the photosensitive element can be easily removed without causing damage. The structure is still snapped onto the clamping sleeve 29. The deflection block 8 has a welding hole 18. One end of the deflection block 8 is rotatably connected to a horizontal bar 9. During the structural adjustment before welding, the horizontal bar 9 is always in a horizontal state. A welding component 17 is slidably connected to one side of the horizontal bar 9. The welding component 17 can heat the welding area by emitting a plasma arc without causing thermal damage to the surrounding area, thus achieving non-contact welding operation. This structure is a direct reference to the prior art. The horizontal bar 9 is rotatably connected to a spring block 11 through a hinge frame 12. A connecting plate 3 is connected to the upper end of the base 1. A second rotating shaft 32 is connected to the connecting plate 3. One end of the spring block 11 is rotatably connected to the second rotating shaft 32. A stabilizing mechanism is connected to the horizontal bar 9 to stabilize the welding state of the semiconductor photosensitive element. By setting the stabilizing mechanism, the photosensitive element can be welded in a stable state, improving the welding accuracy.

[0028] Specifically, such as Figure 4 and Figure 5 As shown, the upper and lower ends of the docking block 5 are connected to the insertion tubes 6, and the deflection block 8 is provided with a docking groove 30. The docking groove 30 and the insertion tubes 6 fit together. By setting the insertion tubes 6, the photosensitive element is limited, which facilitates the assembly of the photosensitive element before welding and the removal of the photosensitive element after welding. At the same time, it also ensures the stability of the position of the photosensitive element during the welding process.

[0029] Specifically, such as Figure 2 As shown, a connecting block 2 is connected to the upper end of the base 1, and a rotating shaft 7 is connected to the connecting block 2. The deflection block 8 is rotatably connected to the rotating shaft 7. By setting the rotating shaft 7 and the connecting block 2, the stability of the rotation of the deflection block 8 is ensured.

[0030] Specifically, such as Figure 4As shown, a symmetrical hole 26 is provided on the horizontal bar 9, and a symmetrical rod 24 is slidably connected to the symmetrical hole 26. The symmetrical rod 24 is fixedly connected to the welded part 17. One end of the symmetrical rod 24 is connected to a limiting piece 10. By setting the limiting piece 10, the symmetrical rod 24 is limited on the horizontal bar 9. The symmetrical rod 24 can also prevent the welded part 17 connected at the lower end from rotating, thereby improving the welding accuracy.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, a pop-out spring 23 is sleeved on the outer side of the symmetrical rod 24. The two ends of the pop-out spring 23 are respectively connected to the welding part 17 and the horizontal bar 9. A storage cover 16 is provided on the outer side of the symmetrical rod 24. The storage cover 16 is fixedly connected to the horizontal bar 9. When there is no external force, the pop-out spring 23 can push the welding part 17 out of the storage cover 16, so that the welding part 17 is in the welding position. This ensures that the welding part 17 is in the welding state as soon as possible. After the welding is completed, the welding part 17 can be stored in the storage cover 16 to protect the precision structure of the welding part 17 and avoid accidental start-up or accidental contact.

[0032] Specifically, such as Figure 4 As shown, a button 28 for controlling the operation of the welding component 17 is connected to the horizontal bar 9. When the button 28 is pressed, the welding component 17 enters the welding operation state. A pressing piece 27 is connected to one side of the limiting piece 10. The pressing piece 27 is located directly above the button 28. The limiting piece 10 enables the welding component 17 to start automatically when it enters the welding position, which greatly improves the welding accuracy.

[0033] Specifically, such as Figure 3 As shown, the stabilizing mechanism includes a handle 13, with a sliding column 14 and a pressure spring 22 connected to the upper end of the handle 13. The sliding column 14 is connected through the horizontal bar 9, and one end of the sliding column 14 is connected to a limit end 15. By setting the sliding column 14, the connection position of the handle 13 can be limited. The cross-section of the sliding column 14 is elliptical, thereby preventing the handle 13 from rotating. The other end of the pressure spring 22 is connected to the horizontal bar 9. The lower end of the handle 13 is connected to a connecting rod 25. A sleeve block 21 is connected to the outside of the spring block 11. The structure of the handle 13 is far away from the welded part 17 and the welding area, which improves the operator's operating safety. During operation, it is only necessary to press the handle 13 and push the spring block 11 to deflect. The operation is simple and easy to learn. A synchronizing rod 19 is connected between the handles 13. By setting the synchronizing rod 19, it is ensured that the two horizontal bars 9 can operate synchronously.

[0034] Specifically, such as Figure 3 and Figure 5As shown, a torsion spring 20 is connected to one side of the spring block 11, and the other end of the torsion spring 20 is connected to the connecting plate 3. The torsion spring 20 is sleeved on the rotating shaft 32. The torsion spring 20 can drive the spring block 11 to deflect. When the spring block 11 is not subjected to external force, the torsion spring 20 can cause the spring block 11 to deflect away from the docking block 5.

[0035] In summary, the plasma welding apparatus for semiconductor photosensitive element production provided in this embodiment allows the lead of the photosensitive element to be inserted into the insertion tube 6 during plasma welding of semiconductor photosensitive elements. The insertion tubes 6 at the upper and lower ends of the mating block 5 are used to position the lead of the photosensitive element, ensuring that the welding position is located at the welding groove 31. The operator also needs to assemble the parts to be welded to the lead onto the clamping sleeve 29. The clamping sleeve 29 can ensure the stability of the connection of the welded parts.

[0036] At this time, the operator presses the handle 13 and the horizontal bar 9, so that the handle 13 overcomes the elastic force of the downward spring 22 and moves towards the horizontal bar 9. By turning the spring block 11, the spring block 11 overcomes the elastic force of the torsion spring 20 and deflects towards the docking block 5. At this time, the horizontal bar 9 gradually moves away from the base 1. At this time, the welded part 17 can be moved out of the storage cover 16 under the action of the pop-out spring 23.

[0037] When the spring block 11 deflects to the vertical position, the deflecting block 8 deflects to the vertical position synchronously under the push of the horizontal bar 9. One side of the deflecting block 8 abuts against the docking block 5. At this time, the insertion tube 6 and the docking groove 30 fit together. Relying on the tight docking between the docking block 5 and the deflecting block 8, the pins of the photosensitive element and the parts welded to it are tightly abutted. At this time, the handle 13 is released. Under the action of the downward spring 22, the handle 13 can push the docking rod 25 connected to one end of the handle 13 to move towards the sleeve block 21. When the docking rod 25 is engaged on the sleeve block 21, the overall structure of the welding device can maintain a stable position.

[0038] Due to the action of the pop-out spring 23, the limiting piece 10 abuts against the horizontal bar 9. At this time, the pressing piece 27 connected to one side of the limiting piece 10 can also press the button 28. At this time, the welding part 17 is activated, and the plasma arc emitted by the welding part 17 passes through the welding hole 18, thereby accurately welding the welding area of ​​the photosensitive element.

[0039] After welding is completed, pressing the handle 13 separates the docking rod 25 from the sleeve block 21. The spring block 11 deflects under the action of the torsion spring 20, thereby driving the horizontal bar 9 to move towards the base 1. The docking block 5 and the deflection block 8 separate from each other, and the operator can easily remove the photosensitive element that has been welded on the docking block 5. When the horizontal bar 9 moves towards the base 1, the horizontal bar 9 and the base 1 can clamp the welded part 17, so that the welded part 17 is stored in the storage cover 16. The button 28 is depressed. The storage cover 16 can effectively protect the welded part 17 and improve the durability of the precision structure.

[0040] When it is time to weld the next photosensitive element, the photosensitive element to be welded and the welding parts can be assembled in the corresponding positions. During welding, the operator does not need to be close to the welding parts 17 to perform the welding operation remotely, which plays an auxiliary role in the welding operation and greatly improves the safety of the photosensitive element welding operation.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
