Tinned wire feeding mechanism, tinned wire point-welding device, and circular capacitor production equipment

Abstract

The invention relates to the field of circuit element production, and discloses a tinned wire feeding mechanism. The tinned wire feeding mechanism comprises a second mounting bracket, a fifth air cylinder, a vertical aligning component, a horizontal aligning component, a pressing assembly, a second linear rail moving assembly, a discharging seat, a sixth air cylinder, a material cutting tool, a bending push plate, and a seventh air cylinder. The tinned wire feeding mechanism solves the problems that planeness of the tinned wire is low, and a weld joint is not firm. Through the vertical aligning component and the horizontal aligning component, the tinned wire is aligned before machining, and therefore planeness of the tinned wire is improved. Through the bending push plate, the tinned wireis bent in an L shape, and therefore the contact area between the tinned wire and a capacitor cylinder is improved, and subsequent point welding is facilitated.

Description

technical field [0001] The invention relates to the field of circuit element manufacturing, in particular to welding equipment for circular cylindrical capacitors. Background technique [0002] Compared with ordinary capacitors, because it is directly installed on the metal panel, the cylindrical capacitor has smaller grounding inductance and almost no influence of lead inductance. In addition, its input and output terminals are isolated by metal plates, which eliminates high frequency Coupling, these two characteristics determine that the cylindrical capacitor has a filtering effect close to the ideal capacitor, and the cylindrical capacitor is composed of a capacitor body and wiring. The shortcomings of the existing production equipment are: 1. The vertical feeding of long cylindrical capacitors is easy to be confused; 2. The turntable works continuously, and the accuracy is low due to error accumulation; 3. The connection between the lead wire and the capacitor is not rel...

AI Technical Summary

Problems solved by technology

The shortcomings of the existing production equipment are: 1. The vertical feeding of long cylindrical capacitors is easy to be confused; 2. The turntable works continuously, and the accuracy is low due to error accumulation; 3. The connection between the lead wire and the capacitor is not reliable, usually directly through soldering The connection is not firm in this way; 4. The lack of positioning in the vertical direction of the capacitor leads to low welding accuracy, and there is interference from dust and impurities during welding; 5. The contact between the lead wire and the capacitor is point contact, which is difficult to weld, and the welding quality is not high
