Description

Technical Field

[0001] This invention relates to the field of spot welding equipment technology, and in particular to a spot welding equipment for processing electronic components. Background Technology

[0002] In the manufacturing process of electronic components, spot welding is a crucial connection process, and its welding quality directly affects the electrical performance, stability, and service life of electronic components. With the rapid development of the electronics industry, electronic components are constantly evolving towards miniaturization, precision, and integration, which places higher demands on the spot welding equipment used for their processing. It is necessary not only to ensure welding accuracy but also to take into account production efficiency, operational safety, and environmental protection.

[0003] Spot welding generates fumes containing harmful gases and metal particles. If not treated promptly, these fumes can diffuse into the working environment, endangering the health of operators. Furthermore, welding slag and other deposits accumulate on the surface of the welding head after prolonged use, affecting welding performance and requiring regular grinding and cleaning. However, existing grinding mechanisms are mostly simple manual grinding or unidirectional mechanical grinding, resulting in grinding dead zones. Moreover, the metal debris generated during grinding can easily fall into the workpiece placement area, contaminating electronic components and further affecting product quality. In addition, existing equipment often uses separate systems for fume treatment and debris collection, which are complex in structure and consume a lot of energy. Therefore, this application proposes a spot welding device for processing electronic components. Summary of the Invention

At the same time, it reduces the safety hazards of manual contact with the high-temperature welding head.

[0018] This invention enables automated cleaning of the welding head, preventing debris from affecting the welding effect and the service life of the welding head, and reducing equipment failure rate and maintenance costs. Attached Figure Description

[0027] Example 1 like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the present invention proposes a spot welding device for processing electronic components, including a worktable 1 and a mounting column 2. The mounting column 2 is fixedly mounted on the worktable 1, and a first cylinder 3 is fixedly mounted on the mounting column 2. A fixing plate 4 is fixedly mounted on the piston rod of the first cylinder 3. A connecting column 12 is rotatably mounted on the bottom of the fixing plate 4. A limit block 17 is slidably mounted on one end of the connecting column 12, and multiple fixing blocks 18 are slidably mounted on the bottom of the limit block 17. A mounting block 20 is fixedly mounted on one side of the fixing plate 4, and a second cylinder 21 is fixedly mounted on the mounting block 20. A welding head 19 is fixedly mounted on the piston rod of the second cylinder 21. The welding head 19 is inclined. A placement platform 23 is rotatably mounted on the worktable 1. The placement table 23 has a placement slot 24 for placing electronic components to be welded, and can drive the electronic components to rotate for welding different parts. The first cylinder 3 is activated, and the piston rod of the first cylinder 3 drives the fixing plate 4 to move downward. The limiting block 17 at the bottom of the connecting column 12 contacts the electronic components, and the fixing block 18 on the limiting block 17 fixes the electronic components. The second cylinder 21 is activated, and the piston rod of the second cylinder 21 drives the welding head 19 to move downward, so that the welding head 19 contacts the electronic components to be welded for welding. The workbench 1 is equipped with a purification mechanism to treat the fumes generated during welding, and a grinding mechanism for grinding the welding head 19 is provided on one side of the workbench 1.

[0028] Example 2 like Figure 1 , Figure 6 and Figure 7 As shown, the purification mechanism includes a fixed base 9 fixedly installed on a workbench 1. A connecting cavity 10 is fixedly installed on the fixed base 9. A guide cavity 29 is rotatably installed on the connecting cavity 10. The guide cavity 29 and the connecting cavity 10 are hollow cavities and communicate with each other. A gear ring 28 is fixedly installed on the guide cavity 29. Multiple smoke tubes 25 are fixedly installed on the guide cavity 29. A gear 6 is rotatably installed on the workbench 1. The gear 6 meshes with the gear ring 28. A first connecting pipe 41 is fixedly installed on one side of the connecting cavity 10. An air pump 44 is fixedly installed on the first connecting pipe 41. An adsorption chamber 13 is fixedly installed on one side of the 44, and an air outlet 14 is fixedly installed on the top of the adsorption chamber 13. During welding, the gear 6 is rotated to start the air pump 44. The gear 6 drives the gear ring 28 to rotate, and the gear ring 28 drives the smoke pipe 25 on the guide chamber 29 to rotate. In conjunction with the air pump 44, the air in the guide chamber 29 is drawn out to form a negative pressure. At this time, the welding smoke can be fully absorbed by the rotating smoke pipe 25, and then transported to the adsorption chamber 13 by the air pump 44. The adsorbent in the adsorption chamber 13 filters the smoke and finally discharges it to avoid harming human health.

[0029] Example 3 like Figure 4 , Figure 6 and Figure 7As shown, the cleaning mechanism includes a guide rod 38 slidably mounted on the workbench 1. A mounting frame 22 is fixedly mounted on the guide rod 38. A slide rod 26 is slidably mounted on the mounting frame 22. A reciprocating screw 27 is rotatably mounted inside the mounting frame 22. The slide rod 26 is threadedly connected to the reciprocating screw 27. A connecting block 30 is fixedly mounted on one side of the slide rod 26. A cleaning plate 32 is rotatably mounted on the connecting block 30. A cleaning cavity 33 is slidably mounted on the cleaning plate 32. The cleaning cavity 33 is hollow. Multiple brush bristles 34 are fixedly installed. A suction port 35 is opened on the cleaning chamber 33. A second connecting pipe 36 is fixedly connected to the bottom of the cleaning chamber 33. A filter compartment 40 is fixedly installed on one side of the second connecting pipe 36. One end of the filter compartment 40 is connected to the first connecting pipe 41. A threaded rod 37 is rotatably installed on the worktable 1. The threaded rod 37 is threadedly connected to the guide rod 38. When it is necessary to clean the welding head 19, a first electronic valve 42 is installed on the first connecting pipe 41, and a second electronic valve 42 is installed on the second connecting pipe 36. When the sub-valve 39 is rotated, the threaded rod 37 is rotated, which drives the guide rod 38 to move, moving the cleaning chamber 33 on one side of the guide rod 38 to the welding head 19, so that the bristles 34 on the cleaning chamber 33 can fully contact the welding head 19. At this time, the reciprocating screw 27 is rotated, which drives the slide rod 26 to make horizontal reciprocating motion on the mounting frame 22. At the same time, the cleaning plate 32 is rotated, which drives the cleaning chamber 33 to rotate, so that the bristles 34 can fully polish the welding head 19 from all directions, avoiding damage. To prevent the dead corners from being affected by the deposits on the surface of the welding head 19, the air pump 44 is started, the first electronic valve 42 is closed, and the second electronic valve 39 is opened. At this time, the air pump 44 extracts the air from the cleaning chamber 33 to form a negative pressure, so that the debris that the brush bristles 34 drop off the welding head 19 can be sucked into the dust suction port 35. The sucked debris is transported to the filter chamber 40 for filtration and collection, preventing the debris from falling into the placement slot 24 and affecting the placement of electronic components, and reducing the safety hazards of manual contact with the high-temperature welding head.

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a rotating shaft 7 is rotatably mounted on the workbench 1, one end of which is fixedly connected to a gear 6. A first motor 8 is fixedly mounted on the bottom of the workbench 1, and the output shaft of the first motor 8 is fixedly connected to a placement platform 23. A second motor 11 is fixedly mounted on the bottom of the workbench 1, and the output shaft of the second motor 11 is fixedly connected to the rotating shaft 7. A third motor 5 is fixedly mounted on one side of the workbench 1, and the output shaft of the third motor 5 is fixedly connected to a threaded rod 37. A fourth motor 15 is fixedly mounted on one side of the mounting frame 22, and the output shaft of the fourth motor 15 is fixedly connected to a reciprocating lead screw 27. A first spring 16 is fixedly mounted on one side of the connecting column 12, and one end of the first spring 16 is fixedly connected to a limiting block 17. A fifth motor 31 is fixedly mounted on the bottom of the connecting block 30, and the output shaft of the fifth motor 31 is fixedly connected to a cleaning plate 32. A second spring 43 is fixedly mounted on the top of the cleaning plate 32, and one end of the second spring 43 is fixedly connected to a cleaning chamber 33.

[0031] Working principle: The electronic component to be soldered is placed in the placement slot 24. The first cylinder 3 is activated, and the piston rod of the first cylinder 3 moves the fixing plate 4 downward. The limiting block 17 at the bottom of the connecting column 12 contacts the electronic component, and the fixing block 18 on the limiting block 17 fixes the electronic component. The second cylinder 21 is activated, and the piston rod of the second cylinder 21 moves the welding head 19 downward, so that the welding head 19 contacts the electronic component to be soldered for soldering. The gear 6 is rotated, and the air pump 44 is activated. The gear 6 drives the gear ring 28. The rotating gear ring 28 drives the smoke extraction tube 25 on the guide cavity 29 to rotate, which, together with the air pump 44, draws out the air in the guide cavity 29, creating a negative pressure. At this time, the welding fumes can be fully absorbed by the rotating smoke extraction tube 25, and then transported by the air pump 44 to the adsorption chamber 13. The adsorbent in the adsorption chamber 13 filters the fumes, and finally discharges them to avoid harming human health. When it is necessary to clean the welding head 19, a first electronic valve 42 is installed on the first connecting pipe 41, and a second electronic valve 39 is installed on the second connecting pipe 36. The threaded rod 37 drives the guide rod 38 to move, moving the cleaning chamber 33 on one side of the guide rod 38 to the welding head 19, so that the bristles 34 on the cleaning chamber 33 can fully contact the welding head 19. At this time, the reciprocating screw 27 is rotated, which drives the slide rod 26 to make horizontal reciprocating motion on the mounting frame 22. At the same time, the cleaning plate 32 is rotated, which drives the cleaning chamber 33 to rotate, so that the bristles 34 can fully grind the welding head 19 from all directions, avoiding grinding dead corners and preventing the adhering substances on the surface of the welding head 19 from affecting the welding. Upon receiving the result, the air pump 44 is started, the first electronic valve 42 is closed, and the second electronic valve 39 is opened. At this time, the air pump 44 extracts the air from the cleaning chamber 33, forming a negative pressure, so that the debris that falls off the welding head 19 from the brush bristles 34 can be sucked in by the dust suction port 35. The sucked debris is transported to the filter chamber 40 for filtration and collection, preventing debris from falling into the placement slot 24 and affecting the placement of electronic components. This achieves automated cleaning of the welding head, avoids debris adhesion affecting the welding effect and the service life of the welding head, and reduces the equipment failure rate and maintenance costs.

[0032] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
