How to choose the sensor for this workstation in the automatic sealing equipment for lithium batteries?
In this issue, Xiaoming will share the application of sensors in the battery fixture detection station of the automatic packaging equipment in the middle process of lithium batteries.
Sealing is a very important processing step in the production process of lithium batteries, and only good sealing can ensure the performance of lithium batteries.
Lithium ion batteries are a complex system with a lengthy production process that involves over 50 steps, divided into front, middle, and back stages. The packaging process belongs to the mid stage production process of lithium batteries, with the production goal of completing the manufacturing of the battery cells. Essentially, it is an assembly process, specifically the orderly assembly of the positive and negative electrode pieces made in the front stage process with the separator and electrolyte. In this issue, Xiaoming will share the application of sensors in the battery fixture detection station of the automatic packaging equipment in the mid stage process of lithium batteries.
Testing requirements
When the fixture for loading cylindrical aluminum shell batteries is in place, the sensor is installed at the aluminum plate feeding position to sense the material is in place and immediately give a signal to drive the cylinder to move. The detection surface should be level or lower than the installation surface to prevent affecting the transmission of the loading device.
Project difficulties
1. The sensor is installed on an aluminum plate, and metal has a strong impact on capacitive proximity sensors
2. The detection object is made of plastic material and the detection surface is cylindrical, so there are requirements for the measurement distance of the sensor
3. Considering the slight deviation in the position of the loading device after it is in place, the insensitivity of plastic materials, the interference of installing aluminum plates, and the vibration impact during machine operation, the product needs to have a certain range of adjustability
