Rapid clamping mould box for battery pack welding

Abstract

The invention discloses a rapid clamping mould box which comprises a movable mould box and a clamping mechanism, wherein the movable mould box is defined by a baseplate, a front end plate, a rear end plate and two side plates, the front end plate and the rear end plate are respectively fixed at the front and rear ends of the baseplate, the two side plates are respectively arranged at the left andright sides of the baseplate and fixedly connected with the front end plate and the rear end plate, and a plurality of baffle plates parallel to the front end plate and the rear end plate are fixed between the two side plates; and the clamping mechanism is used for clamping battery packs, and comprises a connecting plate, two draw bars, a plurality of pressing plates and a rapid clamp, the pressing plates are fixed between the two draw bars and distributed at the intervals of the baffle plates, the rapid clamp is used for driving the connecting plate to make a forward and backward movement and fixedly connected with the connecting plate, the front ends of the two draw bars are respectively fixed at the two sides of the connecting plate, the rear ends of the two draw bars extend along the direction parallel to the side plates, and the connecting plate is fixedly connected with the rapid clamp. The rapid clamp drives the connecting plate to make a forward and backward movement along thedirection parallel to the draw bars, therefore, the clamping stroke of the clamping mould box is long, so that the clamping mould box is suitable to be used for battery packs with various thicknesses, and the type and quantity of the mould boxes are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a quick clamping mold box for welding battery pole groups. Background technique [0002] In the production process of lead-acid batteries, the welding of lead-acid battery electrode groups is a key process, that is, by connecting the positive and negative plates in parallel to achieve the doubling of the capacity of a single plate, and at the same time melting the lead electrodes to form a busbar . During the whole process, the plates, busbars, lead parts (poles, butt weldments, etc.) are connected as a whole, and the separators between the positive and negative plates constitute the core components of the lead-acid battery. [0003] At present, in order to ensure the performance of batteries assembled with glass fiber separators, it is required that the electrode assembly should have a certain assembly pressure when it is inserted into the battery container, that is, ...

AI Technical Summary

Problems solved by technology

Comb-tooth plates are used in conjunction with the mold box when welding the pole group, and the clamping mechanism of the current mold box mostly uses an eccentric wheel or a cam clamping mechanism. The clamping stroke of this kind of clamping mechanism is short, and the self-locking performance is not reliable.
