Technical Field

[0001] This application relates to the field of capacitor processing technology, and in particular to a capacitor welding apparatus. Background Technology

[0002] In the capacitor manufacturing process, lead soldering is a crucial step. Currently, traditional capacitor lead soldering is mostly done manually, requiring operators to hold a soldering iron and solder each lead to the capacitor body one by one.

[0003] This manual welding method has significant drawbacks. First, its welding efficiency is extremely low, making it unsuitable for large-scale production. Second, welding quality is greatly affected by human factors such as the operator's skill level and working condition, easily leading to problems like incomplete welds, missed welds, and incomplete solder joints, resulting in a persistently high product defect rate. Furthermore, with the rising labor costs in the manufacturing industry year by year, the production cost of manual welding is constantly increasing, severely compressing corporate profit margins. Therefore, there is an urgent need to develop an automated capacitor lead welding device to achieve efficient, precise, and stable welding operations, reduce reliance on manual labor, and improve production efficiency and product quality.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application provides a capacitor welding apparatus, such as... Figures 1 to 4 As shown, the device includes a feeding mechanism 1, a welding mechanism 2, a wire feeding mechanism 3, and a clamping mechanism 4 arranged sequentially along the longitudinal direction. A receiving mechanism 5 is provided between the feeding mechanism 1 and the welding mechanism 2. The feeding mechanism 1 is used to transport the capacitor body to the welding position of the welding mechanism 2. The feeding mechanism is used to deliver two leads. The clamping mechanism 4 is used to clamp the two leads and transport them between the capacitor body and the welding mechanism 2. The welding mechanism 2 then welds the two leads to both sides of the capacitor body. After welding is completed, the welding mechanism 2 detaches from the capacitor body, causing the capacitor body to fall into the receiving mechanism 5.

[0023] Compared with the prior art, the capacitor welding device of this application can realize the automated welding of capacitor leads through the cooperation of feeding mechanism 1, welding mechanism 2, wire feeding mechanism 3 and clamping mechanism 4, which improves processing efficiency, can achieve standardized processing, save manpower, reduce the uncertainty of manual welding, and improve the processing yield.

[0024] like Figure 2 and3 As shown, the feeding mechanism 1 includes a base 11, a transverse conveying assembly 12 and a longitudinal conveying assembly 13. The transverse conveying assembly 12 is fixed to one side of the base 11 and is used to convey the capacitor body. The longitudinal conveying assembly 13 is slidably connected to the base 11 along the longitudinal direction and is used to convey the capacitor body to the welding mechanism 2 along the longitudinal direction.

[0025] The transverse conveyor assembly 12 includes a base 121 and a transverse conveyor belt 122. A guide block 1211 is formed on the side of the base 121 near the longitudinal conveyor assembly 13. The longitudinal conveyor assembly 13 includes a sliding seat 131. A guide groove 1311 is formed on the side of the sliding seat 131 near the base 121. The guide groove 1311 extends longitudinally and engages with the guide block 1211. A receiving groove 1312 is formed at the front end of the sliding seat 131. A clamp 132 is connected above the sliding seat 131. The clamp 132 is used to move the sliding seat 131 to one side of the transverse conveyor belt 122. The clamp 132 includes... The system includes a bracket 1321, a baffle 1322, and a drive motor 1323. The bracket 1321 is fixed above and parallel to the sliding seat 131. The drive motor 1323 is fixed to the bracket 1321 and is longitudinally driven and connected to the baffle 1322. The baffle 1322 is rotatably connected to the bracket 1321 and is used to rotate and overlap the front end of the sliding seat 131 via the drive motor 1323. Specifically, the drive motor 1323 drives the upper section of the baffle 1322 longitudinally, causing the baffle 1322 to swing back and forth, thereby overlapping the front end of the receiving groove 1312 or disengaging from the sliding seat 131.

[0026] like Figure 2 As shown, the welding mechanism 2 includes two welding components 21 arranged opposite to each other. The two welding components 21 are respectively located on both sides of the base 11 and are used to weld two leads to both sides of the capacitor body. The welding component 21 includes a fixing seat 211 and a welding head 212. The welding head 212 is driven to be connected to the fixing seat 211. When the clamping mechanism 4 moves the two leads to the capacitor body and the welding head 212 respectively, the welding head 212 moves toward the capacitor body until it presses the leads. The heat of the welding head 212 will gradually increase, melting the solder paste on the leads. Then it will move away. After the solder paste cools down, it can fix the leads to the capacitor body.

[0027] The receiving mechanism 5 is disposed between the two welding components 21 and the base 11, and is located below the two welding components 21. The receiving mechanism 5 includes a receiving bucket 51.

[0028] The wire feeding mechanism 3 includes two wire feeding components 31 arranged opposite to each other. The two wire feeding components 31 are arranged parallel to the two soldering components 21 respectively. They are used to connect to the wire cutting and soldering equipment and to convey the leads that have been coated with solder paste. The wire feeding component 31 includes a V-shaped shelf 311 and a fixing clamp 312. The fixing clamp 312 is located on the outside of the shelf 311. Specifically, the outside of the shelf 311 refers to the side of the shelf 311 facing away from the other shelf 311 after the two shelf 311 are arranged opposite to each other. The wire cutting and soldering equipment first passes the unsoldered end of the lead through the fixing clamp 312 and reaches the inside of the shelf 311. The fixing clamp 312 then clamps the lead to fix it.

[0029] like Figure 2 As shown, the clamping mechanism 4 includes a mounting base 41 and two clamping components 42. The two clamping components 42 are respectively disposed above the two wire feeding components 31 and are used to clamp the leads and move the leads to both sides of the capacitor body.

[0030] like Figure 2 As shown, the mounting base 41 includes a fixed part 411 and a movable part 412. The movable part 412 is driven to the top of the fixed part 411 and is used for reciprocating movement in the vertical direction. The clamping assembly 42 includes a transverse moving arm 421, a rotating arm 422 and a wire clamp 423. The transverse moving arm 421 is driven to the movable part 412 and is used for reciprocating movement in the transverse direction. The rotating arm 422 is fixed to the transverse moving arm 421 and is perpendicular to the transverse moving arm 421. The wire clamp 423 is connected to the rotating arm 422. The movable part 412, the transverse moving arm 421, the rotating arm 422 and the wire clamp 423 are used to move the lead wire on the fixed clamp 312 between the capacitor body and the welding head 212.

[0031] In the specific operation of the capacitor welding device of this application, the capacitor body is transported from the transverse conveyor belt 122 to the end, while the sliding seat 131 moves longitudinally to align the receiving groove 1312 with the transverse conveyor belt 122. The capacitor body is then transported into the receiving groove 1312. At this time, the drive motor 1323 drives the baffle 1322 to overlap the front side of the receiving groove 1312 to prevent the capacitor body from slipping. The sliding seat 131 moves forward to align the mounting groove with the two welding heads 212. Simultaneously, the two wire clamps 423 clamp the leads on the placement plate 311, the fixing clamp 312 releases the leads, the movable part 412 moves upward, and the rotating arm 422 rotates 90 degrees. °, the movable part 412 moves downwards again, causing the two leads to be respectively attached to the left and right sides of the capacitor body and parallel to each other. At this time, the two soldering heads 212 simultaneously approach the left and right sides of the capacitor body and press the leads, while heating the solder paste on the leads to melt the solder paste. At the same time, the drive motor 1323 drives the baffle 1322, causing the baffle 1322 to disengage from the sliding seat 131, leaving space in front of the receiving groove 1312. The sliding seat 131 retracts. At this time, the capacitor body and the leads are suspended in the air by the two soldering heads 212 abutting in opposite directions. After the soldering is completed, the two soldering heads 212 retract, and the soldered capacitor body and leads fall into the receiving hopper 51, thus completing the soldering. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
