Shaping device and method for battery cladding plate before welding

Abstract

The invention relates to the technical field of shaping of battery cladding plates, and particularly discloses a shaping device and method for a battery cladding plate before welding. The shaping device for the battery cladding plate before welding comprises a base plate for containing a plate group. The shaping device is characterized in that the size of the base plate is equal to that of the plate group, a hand guard capable of being folded vertically is arranged on each side edge of the base plate, and a press strip corresponding to positive plate lugs and negative plate lugs is arranged on one side of the base plate. The shaping device is simple in structure, orderliness of positive plates and negative plates can be guaranteed, a partition plate cannot be damaged in the cleaning process, welding is easy, installation of a battery is easy, the working efficiency of workers is improved, and the labor intensity of the workers is reduced.

Description

(1) Technical field [0001] The invention relates to the technical field of battery pack plate shaping, in particular to a battery pack plate shaping device and method before welding. (2) Background technology [0002] Lead-acid battery (large-density battery) plate wrapping shaping is a very important link in the manufacturing process. How to ensure the quality of battery wrapping shaping is inseparable from the design of the wrapping mold. At present, most enterprises in the industry still use manual cladding and manual shaping. The basic steps are: first take a piece of negative plate and put it on the operating table, then put the separator on it evenly, and then stick the positive plate to the separator. Then fold the separator over and place the negative plate, and repeat this process. During the placement process, use your hands to ensure that the plate is in the center of the separator, and then put the wrapped electrode group on the welding frame by hand. During wel...

At present, most enterprises in the industry still use manual cladding and manual shaping. The basic steps are: first take a piece of negative plate and put it on the operating table, then put the separator on it evenly, and then stick the positive plate to the separator. Then fold the separator over and place the negative plate, and repeat this process. During the placement process, use your hands to ensure that the plate is in the center of the separator, and then put the wrapped electrode group on the welding frame by hand. During welding, the biggest problem is that the package is not neat. During this process, the positive and negative plates will move, so that the positive and negative plates cannot face each other. Moreover, there is no pressure on the electrode group before welding, which will cause the tabs to be injured and the bottom of the electrode group to be easily damaged. Damage to the separator will cause the battery to be easily short-circuited, which will seriously affect the battery life, and it will be difficult to install when the case is installed.
