Full-automatic laser welding device for battery production

Abstract

The invention discloses a full-automatic laser welding device for battery production. A clamping jig arranged on a rack is provided with a clip, a first locating device, a second locating device and a gland, wherein the clip is used for fixedly installing a battery and the first locating device and the second locating device are arranged on a PCB. A product feeding device can place the clip on the first locating device. A feeding device on the PCB can place the PCB on the second locating device. Laser beams of the laser welding device can just be projected on the welding spot needed to be welded of the battery and the PCB. An unloading device can place the welded products on a designated location. A controller controls the actions of the product feeding device, the feeding device on the PCB, the clamping jig, the laser welding device and the unloading device. The full-automatic laser welding device realizes full-automatic feeding, welding and detection of nickel and aluminum sheets of the positive and negative electrodes of a cell phone battery, is fast in welding speed and good in quality, avoids the damage to the battery and the PCB, and can ensure that all the welded batteries are qualified products through scanning of battery bar codes by a bar-code scanner before welding.

Description

technical field [0001] The invention relates to an automatic equipment, in particular to an automatic laser welding equipment for battery production. Background technique [0002] In the production process of mobile phones, it is necessary to weld the nickel and aluminum sheets of the positive and negative electrodes of the battery to the PCB board. Due to the small size of the PCB board, it is difficult to position the two during welding. At present, manual welding is mainly used, with slow welding speed and accurate solder joint position. The rate is low, the solder joint size is not standardized, and the battery and PCB board are often artificially damaged during soldering, causing secondary damage and resulting in a high defect rate. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a fully automatic laser welding equipment for battery production. The fully automatic laser welding equipment for battery production ...
