Technical Field

[0001] The utility model relates to the technical field of capacitor processing, in particular to a disc material clamping mechanism of a capacitor welder. Background Technique

[0002] In the process of capacitor manufacturing, the lead welding of capacitors is an extremely important process, mainly to realize the process of welding and fixing the leads to the capacitor cores. At present, the lead welding of capacitors mostly relies on manual operation or is assisted by pneumatic components, which not only leads to low work efficiency, but also makes it difficult to ensure the accuracy and reliability of lead welding, thus directly affecting the qualified rate of products.

[0003] At present, there are also automated devices for capacitor lead welding on the market. However, the material clamping mechanisms of these automated devices all use cylinders to drive material clamping. The disadvantage of cylinder material clamping is that it has complex air pressure pipelines, which is not convenient to implement on small machine platforms. At the same time, the clamping stability of the cylinder is too poor, not suitable for clamping capacitors with smaller sizes, and it cannot adjust the clamped position of the capacitor, and cannot ensure the consistency of the positions of the subsequent welding wires, resulting in a high defective rate of the welded products. For this reason, the inventor designed a disc material clamping mechanism of a capacitor welder. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a disc material clamping mechanism of a capacitor welder, which has the advantages of simple structure, reasonable design, no complex air pressure pipeline design, can clamp multiple capacitors at the same time, and the clamped positions of the capacitors are unified, can ensure the consistency of the welding positions, and at the same time has good clamping stability and high yield of processed products, and solves the problems raised in the above technical background.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A disc material clamping mechanism of a capacitor welder, the disc material clamping mechanism includes a rotating shaft sleeve and a rotating shaft. A disc is fixedly installed on the rotating shaft sleeve. A plurality of installation slots are opened on the disc along its circumferential direction. A material clamping mechanism is installed at each installation slot. A divider is installed at one end of the rotating shaft sleeve away from the disc. The rotating shaft sequentially penetrates through the divider, the rotating shaft sleeve and the disc from bottom to top and is fixedly connected to a scale table. A scale seat is fixedly installed on the scale table. A scale is detachably installed on the scale seat. When the scale rotates, it is in contact connection with the material clamping mechanism.

[0006] Preferably, the disc material clamping mechanism further includes a driving motor, and the output end of the driving motor is connected to the input end of the divider through a belt.

[0007] Preferably, the material clamping mechanism includes a gearbox seat and a slide rod seat, wherein the gearbox seat and the slide rod seat are arranged at intervals at the installation notch. A gearbox body is fixedly installed on the gearbox seat. A small gear is movably installed in the gearbox body, and a left straight tooth and a right straight tooth penetrate through the gearbox body. Both the left straight tooth and the right straight tooth are engaged with the small gear, and a lower clamping rod and an upper clamping rod are respectively fixedly installed on the left straight tooth and the right straight tooth. A clamping bin for clamping the capacitor is formed between the lower clamping rod and the upper clamping rod. A slide rod penetrates through the slide rod seat. One end of the slide rod close to the scale seat is provided with a sliding bearing in contact connection with the scale, and the other end penetrates through the slide rod seat and is in contact connection with the capacitor.

[0008] Preferably, the material clamping mechanism further includes a spring seat. The spring seat is vertically arranged on the slide rod. A spring groove is formed in the spring seat, and a spring is installed in the spring groove. One end of the spring away from the spring groove is in limit connection with the slide rod seat.

[0011] Preferably, the scale is in a fan shape.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model provides a disc material clamping mechanism for a capacitor welding machine. The disc material clamping mechanism includes a rotating shaft sleeve and a rotating shaft. A disc is fixedly installed on the rotating shaft sleeve. A plurality of installation notches are formed in the disc along its circumferential direction. A material clamping mechanism is installed at each installation notch. The overall structure is simple and reasonable in design. The material clamping mechanism includes a gearbox seat and a slide rod seat. A gearbox body is fixedly installed on the gearbox seat. A small gear is movably installed in the gearbox body. The small gear is respectively engaged with the left straight tooth and the right straight tooth. When the right straight tooth moves up and down, it drives the upper clamping rod and the lower clamping rod to move towards each other to clamp the capacitor. Compared with the clamping by a cylinder, there is no complex pneumatic pipeline design, and multiple material clamping mechanisms can clamp multiple capacitors at the same time, with high processing efficiency. By fixedly installing a scale seat on the scale table and detachably installing a scale on the scale seat, the scale is in contact connection with the sliding bearing on the slide rod and pushes the slide rod to move along its length direction, so that the clamping position of the capacitor can be adjusted to ensure the consistency of clamping.

[0025] Specifically, the scale 9 is in a fan shape.

[0026] Please refer to again Figures 1 to 3 , the structure of the disc material clamping mechanism in the present utility model is relatively simple and reasonably designed. The divider 4 can be purchased on the market, and its structure will not be described in detail here. Its function is to evenly distribute the power output by the driving motor 10 to the rotating shaft 5 and provide the rotating power for the rotating shaft 5 through the driving motor 10.

[0027] Please refer to Figure 4 and Figure 5, the clamping mechanism 3 in the figure includes a gearbox seat 31 and a slide bar seat 32. The gearbox seat 31 and the slide bar seat 32 are arranged at intervals at the above-mentioned mounting notch 6. A gearbox body 33 is fixedly installed on the gearbox seat 31. A small gear 34 is movably installed in the gearbox body 33. A left straight tooth 35 and a right straight tooth 36 are arranged through the gearbox body 33. The left straight tooth 35 and the right straight tooth 36 are both engaged with the small gear 34. A lower clamping rod 37 and an upper clamping rod 38 are respectively fixedly installed on the left straight tooth 35 and the right straight tooth 36. A clamping chamber 312 for clamping the capacitor 39 is formed between the lower clamping rod 37 and the upper clamping rod 38. A slide bar 310 is arranged through the slide bar seat 32. One end of the slide bar 310 close to the above-mentioned scale seat 8 is provided with a sliding bearing 311 in contact connection with the scale 9, and the other end penetrates through the slide bar seat 32 and is in contact connection with the capacitor 39.
