Description

Technical Field

[0001] The utility model relates to a welding mechanism, in particular to an upper welding mechanism of a capacitor welder. Background Art

[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, capacitor welders for capacitor lead welding also appear on the market. Generally, they include an upper welding structure, a clamping mechanism and an automatic feeding mechanism. Among them, the upper welding structure generally welds the capacitor cores to the leads. At present, the conventional upper welding mechanisms all adopt soldering irons for welding, with poor welding effects and inconsistent solder joint sizes, resulting in poor use effects of capacitors and high defective rates. At the same time, the soldering iron needs to be connected to an electric wire for conduction, which requires adding a drag chain to protect the electric wire. For a miniaturized capacitor welder, it is completely inconvenient. Therefore, the inventor has improved the structure of the existing upper welding mechanism of the capacitor welder. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an upper welding mechanism of a capacitor welder, which has the advantages of simple structure, reasonable design, can realize conduction welding without complex circuits, has good welding effects and high product yield, and solves the problems raised in the above technical background.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An upper welding mechanism of a capacitor welder includes a base, an upper welding seat, a connecting plate and a welding disc mounting seat. A support column is vertically arranged on the base. A positioning plate and a lower welding seat are installed on one side of the support column. The positioning plate is located above the lower welding seat. A lower welding conductive sheet is fixedly installed on the lower welding seat. The upper welding seat is fixedly installed on the support column. The upper welding seat is connected to the connecting plate through a pin shaft, and a labor-saving lever is formed among the upper welding seat, the connecting plate and the pin shaft. One end of the connecting plate is connected to a push rod, and the other end is connected to the welding disc mounting seat through an insulating plate. A welding wheel shaft core is movably installed on the welding disc mounting seat. One end of the welding wheel shaft core is installed with a welding wheel, and the other end is installed with a mercury slip ring. The mercury slip ring is electrically connected to the welding wheel. The welding wheel cooperates with the lower welding conductive sheet to perform hot melting welding on the capacitor.

[0006] Preferably, a plurality of annular mounting holes are opened on the base, and the plurality of mounting holes are evenly distributed on the base.

[0007] Preferably, upper and lower positioning posts are respectively installed on the upper and lower end faces of the positioning plate, and the upper and lower positioning posts are respectively in contact connection with the welding pad mounting seat and the lower welding seat.

[0008] Preferably, both the lower welding seat and the welding pad mounting seat are made of insulating materials.

[0009] Preferably, a limiting plate is arranged on one side above the upper welding seat. The limiting plate is arranged along the length direction of the connecting plate, and a limiting block is arranged at one end of the limiting plate away from the upper welding seat.

[0010] Preferably, a scraping plate seat is installed on the welding pad mounting seat, a scraping plate is installed on the scraping plate seat, and the scraping plate is arranged at an interval from the welding wheel.

[0011] Preferably, the welding wheel is circular.

[0012] Preferably, a welding wheel wave block is arranged between the welding wheel and the mercury slip ring on the welding wheel axis core. The welding wheel wave block is in contact connection with the limiting block, and a downward pull spring column is arranged on the welding wheel wave block. A spring is installed on the downward pull spring column, and one end of the spring away from the downward pull spring column is fixedly connected with the upward pull spring column on the welding pad mounting seat.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model provides an upper welding mechanism of a capacitor welding machine. The overall structure of the upper welding mechanism is simple and reasonably designed. By fixedly installing a lower welding conductive sheet on the lower welding seat and installing a welding wheel at one end of the welding wheel axis core, when the welding wheel contacts the lower welding conductive sheet, instantaneous high temperature is generated for hot melting welding of the capacitor core and the lead. Among them, an electrical connection is established between the welding wheel and the mercury slip ring, replacing the traditional wire connection, so as to achieve conduction welding without complex circuits, with good welding effect and high product yield.

[0015] 2. The present utility model arranges a limiting plate on one side above the upper welding seat. The limiting plate is arranged along the length direction of the connecting plate, and a limiting block is arranged on the limiting plate. When the push rod drives the connecting plate to move up and down under the action of an external force, the limiting block is in contact connection with the welding wheel wave block on the welding wheel axis core and limits the welding wheel wave block, thereby driving the rotation of the welding wheel axis core. At the same time, the spring is stretched, and the welding wheel axis core drives the welding wheel to rotate, so that the welding wheel and the lower welding conductive sheet are quickly separated, achieving the purpose of rapid heat dissipation, effectively improving the service life of the welding wheel. At the same time, the welding force can be adjusted by the magnitude of the external force to achieve the best welding effect. At the same time, the position of the welding wheel and the lower welding conductive sheet can be positioned, and the welding effect is good. Description of the Drawings

A welding wheel shaft core 20 is movably installed on the welding disc mounting seat 9. One end of the welding wheel shaft core 20 is installed with a welding wheel 12, and the other end is installed with a mercury slip ring 21.

[0026] Specifically, a plurality of annular mounting holes 13 are formed on the base 1, and the plurality of mounting holes 13 are evenly distributed on the base 1. The upper welding mechanism is installed on a capacitor welder (not shown in the figure) through the plurality of mounting holes 13.

[0027] Specifically, an upper positioning column 14 and a lower positioning column 15 are respectively installed on the upper and lower end faces of the positioning plate 3, and the upper positioning column 14 and the lower positioning column 15 are respectively in contact connection with the welding disc mounting seat 9 and the lower welding seat 4.
