Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

In the embodiment shown in fig. 1 and 2, the device for measuring the automatic switch cabinet clamp of the lithium battery charging and discharging cabinet comprises a bracket 1 and a cabinet clamp, wherein the cabinet clamp is formed by alternately arranging positive electrode lug cabinet clamps 5 and negative electrode lug cabinet clamps 6 in a transverse row, the opening and closing directions of the cabinet clamps are the same, the bracket 1 is U-shaped, and the cabinet clamps are arranged in the row and then are perpendicular to the side surface of the bracket 1. The upper part of the cabinet clamp is provided with a compression bar 2 which can move up and down, the compression bar 2 crosses the two sides of the bracket 1 and is parallel to the cabinet clamp, and can move up and down in the limiting grooves 7 on the two sides of the bracket 1. The bracket both sides still are equipped with the controller 4 that drives actuating cylinder 3 and control and drive actuating cylinder 3, and wherein controller 4 is prior art, and the both ends of depression bar 2 and the perpendicular fixed connection of piston rod on driving actuating cylinder 3, and drive actuating cylinder 3 and can drive depression bar 2 and move down to its lower part and the one end contact that the cabinet presss from both sides the control and opens and shuts. The contact part of the lower part of the pressure lever 2 and the cabinet clamp is in a smooth arc shape, so that the cabinet clamp can be prevented from being damaged by repeated pressing, and the service life of the cabinet clamp is prolonged.

During operation, an operator can control the operation of the driving cylinder 3 by operating the controller 4 on the side of each layer of cabinet clamp, and further control the up-and-down movement of the pressure lever 2. The initial state of the pressure lever is positioned at the upper part of the limiting groove 7, at the moment, the pressure lever 2 is not contacted with the cabinet clamp, and the cabinet clamp is closed. When the lithium battery needs to be tested, an operator presses the controller 4, the driving cylinder 3 drives the pressing rod 2 to move downwards to the lower part of the limiting groove 7, at the moment, the pressing rod 2 contacts with one end of the cabinet clamp at the rear part to control opening and closing and presses the cabinet clamp downwards, and the cabinet clamp can be opened. Because depression bar 2 crosses in bracket 1 both sides, consequently depression bar 2 pushes down and to open a whole row of cabinet simultaneously and press from both sides, and the operator puts the lithium cell to adjacent anodal ear cabinet according to positive negative pole in proper order and presss from both sides 5 and the negative pole ear cabinet presss from both sides 6, presses controller 4 once more after putting the completion, and actuating cylinder 3 drives depression bar 2 and rises to the initial point, and the whole row of cabinet presss from both sides and closes simultaneously this moment, accomplishes the last clamp work of whole row of battery, can carry out the charge-discharge test of whole row of battery simultaneously. After the test is accomplished, press controller 4, drive actuating cylinder 3 and drive depression bar 2 decline once more and open the whole row of cabinet clamp, the operator can take out the lithium cell of accomplishing the test to put into the lithium cell that awaits measuring again, repeat above-mentioned step, can realize that pure manual clip-on converts into semi-automatic clip-on. The test and the taking of a whole row of lithium batteries can be realized through one-time operation, the workload of operators is greatly reduced, the production efficiency is improved, only the existing test cabinet needs to be simply transformed, the cost is low, and extra space resources are not occupied.
