Abstract

A square battery heating and pressurizing tray comprises a frame including a bottom plate, two end plates, a baffle and a support rod, wherein the two end plates are installed on the two ends of the bottom plate respectively and are connected through the support rod, and the baffle sleeves the support rod and divides a cavity defined by the end plates and the bottom plate into a battery clamping zone and a clamping degree adjustment zone which are mutually convertible; an adjustable battery clamp mechanism having a plurality of battery clamping blocks, arranged in the battery clamping zone ofthe frame and slidably connected with the support rod; a clamping degree adjusting mechanism detachably mounted in the clamping degree adjustment zone; and a heating mechanism including a plurality ofheating sheets each of which is laid on the wall surface of the corresponding battery clamping block. The square battery heating and pressurizing tray can achieve one-time feeding and only one tray is just required to be heated and pressurized. The square battery heating and pressurizing tray is easy to operate, saves energy, reduces loss, can increase a battery output and reduce production cost.

Description

technical field [0001] The invention relates to a square battery heating and pressing tray. Background technique [0002] With the development of the prismatic battery industry, the existing prismatic batteries bulge during the formation process, resulting in a large number of defective products. In the original battery production technology, heating and pressurizing and charging and discharging are carried out separately, and the time period required for these two processes is long, and heating and pressing are carried out at high temperature, and the environment The high temperature brings great inconvenience to manual operation. In addition, human beings directly touch the battery body when transporting the battery, resulting in a high defect rate of the battery; and the uncertainty caused by human factors is difficult to be effectively controlled. In the case of this kind of repetitive work and complex environment, heating and pressurizing the tray is the best directio...
