Magnetic adsorption cell overturning device

Abstract

The invention provides a magnetic adsorption cell overturning device. A first supporting plate, an air cylinder and a magnet are arranged at one end of an overturning arm. When the magnet is driven bythe air cylinder to get close to or away from the back of the first supporting plate, the magnetic field intensity of the front of the first supporting plate is changed. When the magnet gets close tothe back of the first supporting plate, a strong magnetic field is generated on the front of the first supporting plate to attract a solar cell. When the magnet is far away from the back of the firstsupport plate, the magnetic field on the front of the first supporting plate is weakened to release adsorption to the solar cell. According to the technical scheme, damage, scratches and the like tothe surface of a product due to direct absorption of a cell through a vacuum suction cup can be avoided, a pneumatic system is not needed, high electric energy consumption like an electromagnet is avoided, use and maintenance costs are reduced, and large working noise is avoided.

Description

technical field [0001] The present application relates to the technical field of cell production equipment, in particular to a magnetic adsorption cell flipping device. Background technique [0002] In the thin-film solar cell assembly process, it is a relatively common process step to flip the solar cell to change the front and back of the solar cell to facilitate the next step of assembly. [0003] At present, the more commonly used solar cell flipping device is to use a vacuum suction cup to absorb the cell, and then turn over 180° under the drive of the flip arm to realize the flip of the solar cell. The problem of using this type of equipment to flip solar cells is that a corresponding pneumatic system is required, the cost of use and maintenance is high, the working noise is relatively large, and it is easy to leave marks on the surface of the product. [0004] In related schemes, there is also a cell flipping device that uses the principle of electromagnet adsorption...

AI Technical Summary

Problems solved by technology

The problem of using this type of equipment to flip solar cells is that a corresponding pneumatic system is required, the cost of use and maintenance is high, the work is noisy, and it is easy to leave marks on the surface of the product

The most prominent problem of this method is that the power consumption is relatively high, the maintenance cost during use is also relatively high, and there are hidden dangers of electric leakage.
