Description

Technical Field

[0001] This invention relates to the field of electronic component processing technology, specifically to a spot welding device for processing electronic components. Background Technology

[0002] With the rapid development of microelectronics, new energy electronics, and precision industrial control industries, electronic components are continuously upgrading towards miniaturization, high precision, and high integration, significantly increasing the processing quality requirements for precision components. Spot welding equipment, as a core processing device in the electronics manufacturing field, leverages its advantages of high welding speed, small heat-affected zone, and suitability for processing precision small parts, and is widely used in component pin fixing, contact connection, and assembly processes. The operating accuracy and solder joint uniformity of spot welding equipment directly affect the conductivity, structural stability, and service life of electronic components, making it a key piece of equipment for ensuring the yield rate and operational reliability of electronic products.

[0003] While existing conventional spot welding equipment can perform basic spot welding operations on various electronic components, it still has significant shortcomings in actual mass production. Most existing equipment uses a constant welding current setting, only suitable for single-size workpieces. Even those devices with current adjustment functions require operators to manually switch gears and adjust parameters based on the size of the components, the thickness of the weld joint, and the area of ​​the weld joint, making automated adaptive matching difficult. Manual adjustment relies on operator experience, resulting in lag and limited precision. This easily leads to defects such as weld joint burning and breakdown in small-sized components due to excessive current, and insufficient penetration, incomplete welds, missing welds, and weak welds in large-sized components due to insufficient current. Therefore, the actual performance of spot welding equipment needs improvement.

[0019] 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.

[0020] Example 1 This embodiment provides a spot welding device for processing electronic components; Please see Figures 1-8As shown, the system includes a processing table 1, a welding seat 2 fixed to the upper end of the processing table 1, a conductive winding assembly 3 fixed to the middle of the rear end of the welding seat 2, a three-axis motion platform 4 fixed to the upper end of the processing table 1, and a mounting frame 5 detachably mounted on the drive end of the three-axis motion platform 4 via bolts; the mounting frame 5 is provided with a connecting structure, including a sliding frame 6, a spring 7 fixed to the upper end of the sliding frame 6, a welding head 8 fixed to the middle of the sliding frame 6, an inlet connecting wire 9 fixed to the upper end of the welding head 8, connecting rods 10 slidably connected to both sides of the sliding frame 6, a sliding seat 11 fixed to one end of each connecting rod 10, a stabilizing frame 12 slidably connected to the outer surface of the sliding seat 11, a stabilizing groove 13 opened in the middle of the stabilizing frame 12, a fixing rod 14 fixed to the upper side of the stabilizing frame 12, a connecting frame 15 rotatably connected to the outer surface of the fixing rod 14, a conductive slider 16 rotatably connected to the other end of the connecting frame 15, a fixing seat 17 slidably connected to the outer surface of the conductive slider 16, a winding rod 18 fixed to the middle of the fixing seat 17, and a connecting rod 18 fixed to one end of the conductive slider 16. A lead-out connecting line 19 slides on the conductive winding group 3 via a conductive slider 16, changing the number of winding turns connected to the welding current loop in real time. The three-axis motion platform 4 has a fixed downward stroke. The size of the workpiece determines the actual compression of the spring 7, which in turn determines the sliding displacement distance of the conductive slider 16. When welding large electronic components, the workpiece is lifted to a large height, the spring 7 is compressed to a small amount, and the sliding stroke of the conductive slider 16 is short, connecting only a small number of turns of the conductive winding group 3. The overall resistance of the loop is smaller, and the welding current increases accordingly, matching the large penetration welding parameters required for large workpieces and avoiding problems such as incomplete soldering, detachment, and weak welding. When welding small electronic components, the workpiece is lifted to a small height, the spring 7 is compressed to a large amount, causing the conductive slider 16 to slide significantly, connecting more turns of the conductive winding group 3. The overall resistance of the loop increases, and the welding current decreases accordingly, effectively preventing small workpieces from being damaged by excessive current, such as solder joint erosion, pin burnout, and component breakdown.

[0021] Please refer to it again. Figures 1-8As shown, the outer surface of the sliding frame 6 is slidably connected to the inner wall of the mounting frame 5. The upper side of the sliding frame 6 is fixed to the lower end of the spring 7, and the upper end of the spring 7 is fixed to the upper inner wall of the mounting frame 5. The middle part of the welding head 8 is fixed to the middle part of the sliding frame 6 and passes through the middle of the mounting frame 5. The outer surfaces of the two connecting rods 10 are slidably connected to the inner walls on both sides of the sliding frame 6. One end of the two connecting rods 10 is fixed to both sides of the sliding seat 11. The outer surface of the sliding seat 11 is slidably connected to the inner wall of the stabilizing groove 13. The vertical section of the sliding seat 11 is cross-shaped. The stabilizing groove 13 passes through the middle of the stabilizing frame 12. The two fixed rods 14 are... The end is fixed to the upper side of the stabilizer 12. The outer surface of the stabilizer 12 is slidably connected to the inner wall of the processing table 1. The vertical section of the stabilizer 12 is U-shaped. The outer surface of the fixing rod 14 is rotatably connected to the upper end of the connecting frame 15. The lower end of the connecting frame 15 is rotatably connected to one side of the conductive slider 16. The outer surface of the conductive slider 16 is slidably connected to the inner wall of the fixing seat 17. Both ends of the fixing seat 17 are fixed to the rear side of the welding seat 2. One end of the winding rod 18 is fixed to the middle of the fixing seat 17. The conductive winding group 3 is wound on the winding rod 18. The inner wall of the conductive slider 16 is slidably connected to the outer surface of the conductive winding group 3.

[0022] The specific implementation process is as follows: First, the electronic components to be spot-welded are placed on the welding base 2. Then, the mounting frame 5 is moved and positioned by the three-axis motion platform 4. After the mounting frame 5 is adjusted into position, it moves downward to perform the spot welding operation. The sliding frame 6, which is slidably connected to the inner wall of the mounting frame 5, moves downward accordingly. The insulated sliding frame 6 drives the welding head 8, which is fixed in the middle, to move downward synchronously. At this time, the welding head 8 is not energized. After the downward-moving welding head 8 contacts the workpiece, it remains stationary under the top-stopping limit of the workpiece. The three-axis motion platform 4 continues to drive the mounting frame 5 downward, so that the mounting frame 5 compresses the spring 7 under the support of the stationary sliding frame 6. The downward stroke of the three-axis motion platform 4 is a fixed value. The size of the electronic component workpiece placed on the welding base 2 directly determines the compression amount of the spring 7. When dealing with large workpieces, the downward stroke of the welding head 8 and the sliding frame 6 is small. The connecting rod 10, which is slidably connected to both sides of the sliding frame 6, drives the sliding seat 11, which is fixed at the end, to move downward synchronously. The downward sliding seat 11 slides along the inner wall of the stabilizing groove 13, driving the stabilizing frame 12 to move downward synchronously under the limiting action of the inner wall of the processing table 1. The downward moving stabilizing frame 12 drives the fixed rod 14 to move synchronously. The fixed rod 14, through the rotatably connected connecting frame 15, drives the conductive slide plate 16, which is rotatably connected at the other end, to slide in a limited manner inside the fixed seat 17 fixed on the welding seat 2 and outside the conductive winding group 3 wound on the surface of the winding rod 18 on the fixed seat 17. For large workpieces, the sliding frame 6 has a small downward movement, the conductive slider 16 has a small travel distance, the current flows through fewer turns of the conductive winding group 3, and the circuit impedance is small, thus increasing the welding current to meet the high-current welding requirements of large workpieces. For smaller workpieces, the sliding frame 6 has a large downward movement, the conductive slider 16 has a large travel distance, the current flows through more turns of the conductive winding group 3, and the circuit impedance is large, thus decreasing the welding current to suit the low-current welding conditions of small workpieces. During welding, the lead-in connecting wire 9 is energized through the welding head 8 to perform spot welding on the workpiece. The current is conducted through the workpiece to the welding seat 2, then sequentially through the conductive winding group 3 and the conductive slider 16, and finally forms a complete current loop through the lead-out connecting wire 19. It achieves adaptive spot welding without the need for manual adjustment of the current level. It can automatically match the corresponding welding current according to the shape and size of the electronic component workpiece, and complete the adaptive current adjustment. It can adapt to batch spot welding operations of electronic components of different models and sizes, effectively avoiding the problem of excessive current burning the solder joint for small workpieces and insufficient current causing poor soldering or missing solder joints for large workpieces. The welding consistency and operational stability are greatly improved, effectively enhancing the overall performance of the spot welding device.

[0023] Example 2 When spot welding electronic components, the traditional method requires manual or auxiliary tooling to align, straighten and position the workpiece before spot welding can be carried out. The whole process is cumbersome and time-consuming. Therefore, it is necessary to design a structure that can automatically center and self-position electronic components, eliminate the manual calibration and positioning step, simplify the operation process and greatly improve the overall processing efficiency of spot welding equipment.

[0024] Please see Figures 1-8 As shown, an automatic centering and positioning function has been added based on Embodiment 1; Please refer to it again. Figures 1-8As shown, support frames 20 are fixed on both sides of the stabilizer 12. Sliding rods 21 are slidably connected to the inner walls of both support frames 20. Guide frames 22 are slidably connected to the outer surfaces of both sliding rods 21. Guide grooves 23 are provided in the middle of both guide frames 22. Connecting frames 24 are fixed to one end of each sliding rod 21. Sliding blocks 25 are rotatably connected to the other ends of both connecting frames 24. Positioning frames 26 are detachably installed in the middle of each sliding block 25 via bolts. A sliding groove 27 is provided on the front side of the processing table 1. The near ends of the two support frames 20 are fixed to both sides of the stabilizer 12. The vertical cross-sections of both support frames 20 are L-shaped. The outer surfaces of the two sliding rods 21 are slidably connected to the inner walls of the support frames 20, and the outer surfaces of the sliding rods 21 are slidably connected to the inner walls of the guide grooves 23. The guide rail 23 runs through the upper side of the guide frame 22, and its cross-section is V-shaped. The lower end of the guide frame 22 is fixed to both sides of the processing table 1. One end of each of the two sliding rods 21 is fixed to the opposite ends of the two connecting frames 24, and the near ends of the two connecting frames 24 are rotatably connected to one side of the two sliding blocks 25. The outer surfaces of the two sliding blocks 25 are slidably connected to the inner walls of both sides of the slide groove 27. The vertical cross-section of each sliding block 25 is L-shaped. One end of each of the two positioning frames 26 is detachably installed in the middle of the sliding block 25 by bolts. The outer surfaces of the two positioning frames 26 are slidably connected to the upper surfaces of both sides of the welding seat 2. The positioning frames 26 provide bidirectional centering, clamping, and limiting of the electronic components placed on the welding seat 2, automatically correcting the offset and skew of the workpiece during placement, so that the workpiece weld point is accurately aligned with the welding center of the welding head 8. The positioning frames 26 adopt a bolt-detachable installation structure, which can be quickly replaced and adapted to different specifications and sizes of components, with a wide range of adaptability.

[0025] The specific implementation process is as follows: The mounting frame 5 is moved and adjusted by the three-axis motion platform 4, so that the sliding frame 6, which is slidably connected to the inner wall of the mounting frame 5, moves stably downward under the elastic support of the spring 7. During the downward movement, the sliding frame 6 drives the sliding seat 11 to move downward synchronously through the sliding connecting rod 10, thereby driving the overall downward movement of the stabilizing frame 12; the downward movement of the stabilizing frame 12 drives the support frames 20 fixed on both sides to move vertically synchronously. During the downward movement of the support frame 20, the sliding rod 21, which is slidably connected to the inner wall of the guide groove 23 of the guide frame 22, is squeezed and driven by its own groove structure, forcing the sliding rods 21 on both sides to move downward synchronously along the trajectory of the guide groove 23. The two downward sliding rods 21 drive the two sliding blocks 25 to perform a centering and clamping action under the limitation of the inner walls on both sides of the slide groove 27 through the two connecting frames 24 fixed at the ends. In the early downward movement stage before the welding head 8 contacts the workpiece, the sliding rod 21 will first slide to the inflection point of the guide groove 23, and smoothly lock into the inflection point under the continuous downward squeezing action of the support frame 20; when the sliding rod 21 moves to the lowest limit position of the inflection point of the guide groove 23, the vertical end face of the support frame 20 just presses and limits the sliding rod 21 stably at the lowest point of the guide groove 23, realizing the self-locking position of the structure; At this time, the two sliding blocks 25 drive the positioning frame 26, which is detachably installed by bolts, to retract synchronously, automatically completing the centering and precise positioning of the electronic component workpiece on the welding seat 2, effectively correcting the workpiece placement deviation, and ensuring that the workpiece welding point is accurately aligned with the center of the welding head 8. After the workpiece is positioned, the welding head 8 continues to move down with the sliding frame 6 and finally contacts the workpiece surface for welding. Throughout the subsequent process of adaptive fine-tuning of the welding head 8, changes in the compression of the spring 7, and current adjustment, the vertical end face of the support frame 20 always exerts continuous pressure on the sliding rod 21, keeping the sliding rod 21 stably locked at the bottom of the guide groove 23, ensuring that the positioning frame 26 remains clamped and positioned throughout the process, and will not loosen, shift, or reset during the adaptive adjustment of the spot welding. The automatic centering and positioning function can automatically correct the workpiece placement position before spot welding. The entire process does not require manual alignment, positioning and calibration of the workpiece, eliminating the tedious manual positioning process of traditional spot welding operations, greatly simplifying the overall operation process, effectively shortening the workpiece clamping and positioning time, and significantly improving the overall processing efficiency of the spot welding device.

[0026] Example 3 After welding, electronic components are small in size, and the gap between them and the welding table is extremely small, making manual handling very inconvenient. Therefore, it is necessary to add an automatic ejection mechanism after welding to automatically lift the spot-welded workpiece, increase the gap between the workpiece and the welding table, facilitate quick removal of the component, and effectively improve the ease of use of the spot welding device.

[0027] Please see Figures 1-8 As shown, an automatic workpiece lifting function has been added based on Embodiment 1; Please refer to it again. Figures 1-8 As shown, each of the two sliding blocks 25 has a support rod 28 fixed on one side. The outer surfaces of the two support rods 28 are slidably connected to a lifting frame 29. The lifting frame 29 has inclined grooves 30 on both sides. The welding seat 2 has a limiting groove 31 in the middle. One end of the two support rods 28 is fixed to one side of the two sliding blocks 25. The outer surfaces of the two support rods 28 are slidably connected to the inner walls of the two inclined grooves 30. The two inclined grooves 30 pass through both sides of the lifting frame 29. The outer surface of the lifting frame 29 is slidably connected to the inner wall of the limiting groove 31. The vertical section of the lifting frame 29 is T-shaped. The limiting groove 31 passes through the middle of the upper end of the welding seat 2.

[0028] The specific implementation process is as follows: After the spot welding operation is completed, the mounting frame 5 is driven upward and reset by the three-axis motion platform 4, so that the sliding frame 6, which is slidably connected to the inner wall of the mounting frame 5, moves upward and resets synchronously with the mounting frame 5. During the upward movement, the sliding frame 6 drives the sliding seat 11 to move upward synchronously through the sliding connecting rod 10, thereby driving the stabilizing frame 12 to move vertically upward as a whole. The upward movement of the stabilizing frame 12 drives the support frames 20 fixed on both sides to move upward synchronously. During the upward movement, the support frames 20 on both sides gradually release the limiting pressure on the sliding rod 21 and rise with the stroke to push the sliding rod 21 upward synchronously, so that the two sliding rods 21 slide upward and reset along the trajectory of the guide groove 23. At the same time as the two sliding rods 21 move upward, they drive the connecting frame 24 fixed at the end to move synchronously, thereby driving the two sliding blocks 25 to perform a release and reset action away from each other under the limiting guidance of the inner walls on both sides of the slide groove 27. Two sliding blocks 25 that are far apart from each other synchronously drive the support rod 28 fixed on one side to move outward. Under the guidance of the inclined surface of the corresponding inclined groove 30, the two support rods 28 convert the horizontal outward movement stroke into a vertical upward pushing stroke. Under the precise limiting constraint of the limiting groove 31 opened in the middle of the welding seat 2, the lifting frame 29 moves vertically upward stably. The top surface of the lifting frame 29 uniformly lifts the electronic component workpiece that has been spot welded, realizing the effect of automatic lifting of the workpiece. This effectively increases the gap between the bottom of the workpiece and the table surface of the welding seat 2, solving the problems of small electronic components being close to the table surface, having limited operating space, and being difficult to pick up manually, thus effectively improving the ease of operation of the spot welding device.
