The invention has the advantages and beneficial effects that:
The invention provides a mesh pulling process, which adopts a pair of manipulators to stretch steel wire mesh cloth, and can stretch the meshes of the steel wire mesh cloth from square to diamond.
The invention adopts the mechanical arm to replace manpower, can more effectively produce and can stabilize the quality of the stretched mesh cloth.
Compared with manual stretching, the invention can more accurately adjust the required angle.
The invention can more accurately control the stretching angle, reduce the labor cost, and ensure the quality of the mesh cloth to be above a certain level, so that the error value can be reduced in the subsequent process.
The invention uses the mechanical arm to stretch the mesh cloth, so that the human factors are reduced to the minimum, the productivity can be improved, and the yield can be improved.
According to the invention, a layer of fixed adhesive film is paved on the steel wire mesh cloth, and the fixed adhesive film and the mesh cloth are brushed back for 3-4 times by using the electrostatic brush, so that static electricity can be removed, the fixed adhesive film and the mesh cloth are tightly attached, no bubbles exist after the attachment, and the fixed adhesive film and the mesh cloth are leveled.
