Technical Field

The invention relates to a capacitor guide pin formation device, in particular to a magnetic bar which is convenient for replacing a magnetic bar and used for capacitor guide pin formation.

Background

With the rapid development of chip capacitors, new technical requirements are put forward on outgoing lines of the capacitors, and the original outgoing lines can be used on a machine only after being formed and spot-welded and cleaned. At present, the development needs to meet the requirements of electrical parameters, such as voltage resistance, leakage current and the like, because the outgoing line is made of two different materials, namely a high-purity aluminum wire and a tinned copper clad steel wire (CP wire) in the processing and manufacturing process, the forming treatment is carried out on the high-purity aluminum wire forming part. The lead-out wires formed by spot welding are orderly arranged in an aluminum cup before formation to ensure that the directions of the high-purity aluminum wires and the CP wires are consistent, the high-purity aluminum wires are kept below the formed part, the CP wires are not allowed to fall off in the formation process, and otherwise, short circuit is caused in the formation process.

Patent numbers: 201520713621.4, a magnetic bar for lead-out wire fabrication; which discloses a magnetic bar. Because need lean on magnetic force to hold the material cup of condenser guide pin and condenser guide pin, so the magnetic force that needs is great, and in the in-process of using, the bar magnet inevitable can meet the phenomenon that the magnetic sheet needs to be changed, and this kind of bar magnet of comparison document is owing to place the thin slice with magnetism in bowl shape container for very inconvenient when changing the magnetic sheet.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the magnetic bar for capacitor guide pin formation, which is convenient for replacing the magnetic bar.

In order to solve the technical problems, the technical scheme provided by the invention is as follows: a magnetic bar for capacitor guide pin formation comprises a base and a magnetic strip, wherein the bottom of the base is provided with an opening to form an accommodating cavity, the magnetic strip is fixedly arranged in the accommodating cavity, a cover plate is fixedly connected to the opening of the base, and the magnetic strip is hermetically arranged in the accommodating cavity through the cover plate; the top surface fixedly connected with of base puts the flitch, it is provided with a plurality of circular ports of placing condenser guide pin material cup on the flitch to put.

Preferably, the magnetic bar is located right below the circular hole; rubber connecting blocks are arranged at two ends or the periphery of the magnetic strip; the rubber connecting block is fixedly connected in the accommodating cavity through a bolt.

The magnetic bar for capacitor guide pin formation is preferably completely wrapped by rubber or plastic.

The magnetic rod for capacitor guide pin formation is preferred, the base and the material placing plate are integrally formed into a whole base, and a plurality of circular holes for placing capacitor guide pin material cups are formed in the top surface of the base.

Preferably, the depth of the circular hole is 2-5 mm.

Preferably, the diameter of the circular hole is 1-3mm larger than the diameter of the material cup of the capacitor guide pin.

Preferably, the plurality of circular holes are uniformly formed on the top surface of the material placing plate or the base.

Compared with the prior art, the invention has the advantages that: when the magnetic bar for capacitor guide pin formation is used for replacing the magnetic strip, a new magnetic strip can be replaced only by opening the cover plate from the bottom of the base, so that the magnetic bar is very convenient; therefore, the magnetic bar for capacitor guide pin formation is simple to maintain.
