Accumulator plate packaging machine and pole plate feed mechanism thereof

Abstract

The present application discloses an accumulator plate packaging machine and a pole plate feed mechanism thereof. The pole plate feed mechanism comprises: a supporting plate, a cylinder, an ascending air passage and a descending air passage, wherein the cylinder is provided with a cylinder block and a piston; the piston divides a cavity of the cylinder into an upper cavity and a lower cavity; one segment of the piston is connected to the supporting plate and drives the supporting plate to ascend or descend; the ascending air passage is communicated to the lower cavity of the cylinder and controls the piston to ascend; and the descending air passage is connected to the upper cavity of the cylinder and controls the piston to descend. According to the present application, pneumatic control is used instead of gas-liquid hybrid control, a long period operation of the cylinder in a humid environment is avoided, and even in a severe environment with more dust, a sealing ring in the cylinder also can be effectively protected, so that a service life of the cylinder is longer than that of a gas-liquid hybrid cylinder.

Description

technical field [0001] The application relates to battery processing equipment, in particular to a plate feeding mechanism for a battery wrapping machine. Background technique [0002] In the process of battery assembly and production, one of them is called "electrode group matching group", which is collectively referred to as "package board" below. "Package board" is to arrange the positive plate, negative plate and separator according to the specified Sequence, polarity, the process of combining into a plate separator body. "Wrapping" is divided into manual wrapping and mechanical wrapping. Manual wrapping has been gradually eliminated, and various mechanical wrapping machines have been developed in the society, that is, battery wrapping machines. [0003] There is a mechanism in the battery wrapping machine called the electrode plate feeding mechanism. The function of this mechanism is mainly to control the positioning of the plate gap and upward conveying. This deliver...

AI Technical Summary

Problems solved by technology

[0004] At present, the internal sealing ring of the cylinder produced by the manufacturer is easily corroded after being soaked in oil for a long time, causing internal and external leakage of the cylinder, and oil spraying outside, which cannot control the normal rise and fall

Moreover, the production environment is relatively harsh and there is a lot of dust. In a humid environment (there is oil on the cylinder rod), the dust is more likely to adhere to the cylinder rod, and the cylinder rod moves back and forth, which will bring the dust into the cylinder. friction, resulting in damage to the sealing ring, resulting in problems such as internal and external leakage of the cylinder, and fuel injection outside the cylinder
