[0053] When the utility model is in use, the protective plate loading mechanism 2 loads the battery protection plate, and the battery loading mechanism 4 loads the small poly battery 100; then the protective plate welding loading mechanism 3 transfers the battery protection plate group on the protective plate loading mechanism 2 to the welding mechanism 7, and the battery loading mechanism 4 corrects the deviation of the small poly battery 100 and takes photos and measures the size of the pole ear of the small poly battery 100, and then the battery welding loading mechanism 6 transfers the small poly battery 100 on the battery correction and photography mechanism 5 to the welding mechanism 7, and the welding mechanism 7 welds the small poly battery 100 with the corresponding battery protection plate, and finally, the battery welding loading mechanism 6 transfers the welded small poly battery 100 to the unloading mechanism 8 for unloading, and this cycle is repeated. The utility model can realize the fully automatic welding of the small poly battery 100 and the battery protection plate, which can improve the welding efficiency, reduce the cost, and ensure the consistency and reliability of the product quality.
