Automatic one-step welding device for cylindrical battery pins

Abstract

The invention discloses an automatic one-step welding device for cylindrical battery pins. The automatic one-step welding device comprises a fixed board. A welding positioning mold is fixedly arranged at the center of the fixed board; around the welding positioning mold, a movable battery welding nozzle device, an electrode wire cutting mechanism and an electrode wire straightening mechanism are respectively symmetrically arranged on two horizontal sides from inside to outside; a movable battery feed and discharge mechanism is arranged between one side of the welding positioning mold and the electrode wire cutting mechanism; a feeding mechanism is arranged on one side of the welding positioning mold perpendicularly. Except the battery feeding that is completed manually, other procedures are completed at one step mechanically, and thus work efficiency is improved greatly. In terms of reduction of material cost, reduction of processing procedures, manual welding efficiency and the like, the automatic one-step welding device has the welding effect that is a dozen times of the conventional production effect; production efficiency is improved greatly while labor intensity of workers is lowered greatly.

Description

technical field [0001] The invention relates to the field of primary lithium battery product assembly, in particular to a one-time automatic welding device for cylindrical battery pins. Background technique [0002] The current two types of batteries, ER14505 and CR14505, require soldering pins with a diameter of 0.8mm and a length of 45mm at both positive and negative ends. The current production process is to purchase the lead pins that have been cut and weld them manually. Because it is manual welding, the contact between the lead pins and the negative electrode is not reliable when the negative electrode is welded, which will lead to the current output of the welding machine. Stability, which will cause explosion when the lead pin and the negative electrode are welded. In severe cases, the bottom of the battery may be penetrated, resulting in the scrapping of the battery and may even cause injury to the operator. In order to prevent this from happening again, we have to...

Problems solved by technology

Although this traditional process method is feasible in the production process, in terms of material cost, the cutting of lead pins and the increase of pole pieces will increase the material cost of a single product, and the increase in the process will also increase the manufacturing cost. At the same time, due to the manual operation, the production efficiency is also restricted accordingly.
