Description

Technical Field

[0001] The invention relates to the field of capacitor production, in particular to a pin welding device used for capacitor production. Background Art

[0002] A capacitor is an electronic component that can store electrical energy. It consists of two conductors (electrodes) and an insulating medium (dielectric) in the middle. When voltage is applied across the capacitor, the positive plate accumulates positive charge and the negative plate accumulates negative charge, forming an electric field to store electrical energy. After the power is disconnected, the charge can still be maintained to achieve energy storage. In electronic circuits, it has multiple functions such as filtering, coupling, tuning and energy storage.

[0003] When producing capacitors, it is necessary to use welding equipment to weld the core and pins of the capacitor, so that two welding bases stick the two pins on the end faces of the gold-sprayed layer on both sides of the core, and then weld them through a welding gun. When welding capacitors of different sizes, in order to ensure that the welding gun just contacts the capacitor and the pins during movement, the position of the welding gun needs to be adjusted. The existing welding device uses a combined installation method to adjust the distance between the two welding guns. However, this adjustment method requires the staff to first turn off the core conveying equipment before adjusting the distance of the welding base. After the adjustment is completed, the conveying equipment can be started to weld the pins and the core again. This process cannot weld the pins and the core normally, affecting the production efficiency of the capacitor. Summary of the invention

[0022] Example 2: Please refer to Figure 6 and Figure 8, this embodiment further explains the first embodiment. The clamping mechanism shown in the figure includes two sliders 18 symmetrically slidably installed on the inner side of the moving frame 10. A guide rod 19 sliding through the slider 18 is fixedly installed on the inner side of the moving frame 10. Two symmetrically distributed sliding balls 38 are rotatably installed at the bottom of the slider 18. A sliding groove for limiting the sliding of the sliding balls 38 is provided on the inner side of the moving frame 10 to improve the smoothness of the slider 18 when moving. A mounting rod 20 is fixedly installed on the top of the slider 18. A guide inclined groove for limiting the mounting rod 20 is provided on the outer side of the U-shaped frame 4, so that when the moving frame 10 moves, the mounting rod 20 on the slider 18 can be driven to move along the guide inclined groove, so that the mounting rod 20 drives the slider 18 to move along the inner side of the moving frame 10 and the outer side of the guide rod 19, so as to realize the inclined movement of the mounting rod 20. The four mounting rods One end of 20 away from the slider 18 is fixedly connected to the four L-shaped clamping plates 5 respectively, so that when the four mounting rods 20 move, the four L-shaped clamping plates 5 can be driven to move in a diffused or close manner, which is convenient for clamping and fixing capacitor cores of different sizes. Two symmetrically distributed spring rods 21 are slidably installed on one end of the L-shaped clamping plate 5 away from the mounting rod 20, and a rubber clamping plate 22 is fixedly installed between the two spring rods 21. The elasticity of the spring rod 21 is utilized to make the rubber clamping plate 22 elastically clamp and position the outer side of the capacitor core to prevent excessive clamping force on the capacitor chip and avoid damage. A placement frame 23 is provided between the four L-shaped clamping plates 5, and the placement frame 23 is fixedly installed on the outer side of the U-shaped frame 4. The staff can place the capacitor core on the placement frame 23, so that the rubber clamping plate 22 on the L-shaped clamping plate 5 clamps and positions the capacitor chip.

[0023] Example 3: Please refer to Figure 2 , Figure 5 and Figure 6, this embodiment further explains other embodiments, the discharge mechanism shown in the figure includes two fixed plates 24 symmetrically fixedly installed on the inner side of the U-shaped frame 4, a push plate 25 is slidably installed on the inner side of the placement frame 23, and two symmetrically distributed support rods 26 are fixedly installed on the side of the push plate 25 close to the U-shaped frame 4. When the support rod 26 moves, the capacitor core on the placement frame 23 can be pushed out from between the four L-shaped clamping plates 5 through the push plate 25, and the support rod 26 slides through the U-shaped frame 4 and the two fixed plates 24. A second mounting plate 27 is fixedly installed between the ends of the two support rods 26 away from the push plate 25. A positioning spring 28 is arranged on the outer side of the support rod 26, and the positioning spring 28 is fixedly installed between the second mounting plate 27 and the fixed plate 24. When the second mounting plate 27 is pushed, the positioning spring 28 can be compressed, and the elasticity of the positioning spring 28 can be used to make The second mounting plate 27 is reset, and a contact ring 29 is provided on the inner side of the rotating drum 2. A plurality of positioning rods 30 symmetrically distributed are fixedly installed between the outer side of the contact ring 29 and the adjacent mounting frame 1, so that the contact ring 29 is fixed in the internal position of the rotating drum 2. An arc plate 31 is fixedly installed on the side of the second mounting plate 27 away from the support rod 26. The outer side of the arc plate 31 contacts the outer side of the contact ring 29, so that when the rotating drum 2 rotates, the arc plate 31 can move along the outer side of the contact ring 29. An arc-shaped protrusion 32 is fixedly installed on the bottom of the contact ring 29. When the arc plate 31 contacts the arc-shaped protrusion 32, the arc-shaped protrusion 32 can push the arc plate 31 in the reverse direction to move, thereby realizing the movement of the push plate 25. Two symmetrically distributed retaining rings 39 are fixedly installed on the outer side of the contact ring 29. The arc plate 31 is located between the two retaining rings 39 to provide guidance for the movement of the arc plate 31.

[0024] Working principle: First, the staff places the capacitor core on the top of the placement frame 23 above the rotating drum 2, so that the capacitor core enters between the four L-shaped clamping plates 5, and uses the elasticity of the spring rod 21 to clamp and position the capacitor core with the four rubber clamping plates 22. The driving motor 3 can drive the rotating drum 2 to rotate intermittently, so that the rotating drum 2 drives the capacitor core between the placement frame 23 and the four L-shaped clamping plates 5 to move between the two welding guns 7, so that the welding guns 7 weld the pins on the capacitor core. At the same time, the staff places the next capacitor core on the top of the placement frame 23 located above the rotating drum 2 at this time. Thus, with the intermittent rotation of the driving motor 3, continuous welding of the capacitor core is achieved. The second mounting plate 27 is connected to the rotating drum 2, and when the capacitor core after welding moves to the bottom of the rotating drum 2, the U-shaped frame 4 drives the second mounting plate 27 between the two supporting rods 26 to move synchronously, so that the arc plate 31 on the second mounting plate 27 contacts the arc convex block 32 on the contact ring 29, and the arc plate 31 pushes the second mounting plate 27 to move by utilizing the reaction force of the arc convex block 32 on the arc plate 31. While the second mounting plate 27 compresses the positioning spring 28, it pushes the two supporting rods 26 to move synchronously, so that the supporting rods 26 push the push plate 25 to move downward, and the capacitor core between the four L-shaped clamping plates 5 is pushed out, so as to realize the automatic discharge of the capacitor core, thereby achieving the effect of continuous welding processing and automatic discharge; When it is necessary to weld a large-sized capacitor core, the staff starts the gear motor 17, the gear motor 17 drives the transmission gear 16 to rotate, so that the transmission gear 16 drives the driven gear 15 to rotate, and the driven gear 15 can drive the counter-rotating screw 9 to rotate, and the counter-rotating screw 9 drives the two moving frames 10 to move away from each other through the two moving blocks 8, and the moving frame 10 drives the slide bar 12 to move synchronously, so that the slide bar 12 drives the mounting ring 11 to move, and the mounting ring 11 drives the arc-shaped sleeve clamp 14 to move synchronously, so that the arc-shaped sleeve clamp 14 drives the welding gun 7 to move through the second mounting plate 27, and the two welding guns 7 can move away from each other. At the same time, the moving frame 10 drives the slide block 18 on the slide block 18. The mounting rod 20 moves along the guide inclined groove, so that the mounting rod 20 drives the slider 18 to move along the inner side of the moving frame 10 and the outer side of the guide rod 19, thereby realizing the inclined movement of the mounting rod 20. The mounting rod 20 drives the corresponding L-shaped clamping plates 5 to move synchronously, so that the four L-shaped clamping plates 5 move in a diffused or close manner, and the distance between the four rubber clamping plates 22 is increased, so that the capacitor core of a larger size can be clamped and fixed. Therefore, the capacitor cores of more sizes can be welded without stopping the machine, solving the problem that the traditional welding device needs to be stopped for disassembly and assembly, thereby ensuring the efficiency of welding the capacitor core and the pin, and facilitating the continuous production of capacitors.
