Locking device for battery restraining tray

Abstract

A locking device for a battery restraining tray comprises a base, a front-back driving device, and a synchronous movement mechanism, wherein the top of the base is provided with a mounting platform; the front-back driving mechanism is arranged on the base, and comprises a driving device, a fixed guide rail sliding block assembly, and a sliding block fixing plate; a pushing end of the driving device is connected with the fixed guide rail sliding block assembly; a sliding part of the fixed guide rail sliding block assembly is fixedly provided with the sliding block fixing plate; the sliding block fixing plate is connected with the pushing end of the driving device by a connecting piece; the synchronous movement mechanism is arranged on the front-back driving mechanism, and comprises a motordriving device, a torque limiting device, a lead screw transmission device, a synchronous pulley transmission device, and a movable guide rail sliding block device; the motor driving device is mountedon the sliding block fixing plate in a sliding manner by the movable guide rail sliding block device; a sleeve head is assembled at an end of an output shaft of the torque limiting device; and the screw rod transmission device is in belt connection with the output shaft of the torque limiting device by the synchronous pulley transmission device. The locking device has the beneficial effects of improving production efficiency, pipelining a product, and facilitating production automation.

Description

technical field [0001] The invention relates to a battery restraint tray locking device, which belongs to the technical field of battery composition capacity testing. Background technique [0002] In the automatic production process of lithium batteries, especially in the process of forming and sizing, the shape of the battery cell will bulge due to the formation of gas, which directly affects the appearance quality of the battery cell. Therefore, in the test process, in order to ensure the consistency of the battery dimensions, it is necessary to use a restraint tray to compress the battery and give a given pressure. At present, the cylinder is directly compressed and opened, and the control of the force is uneven and cannot be fed back. The size of the force and the stroke control of the expansion and contraction are easy to overvoltage or undervoltage on the battery. Contents of the invention [0003] The purpose of the present invention is to provide a simpler and mor...
