PV vacuum box (dry sheet stabilizer)

Vacuum box is a kind of degassing equipment mainly used for objects with high air content, which has fast degassing rate, high automation degree and wide application range. Vacuum box is a kind of machine equipment used for degassing objects with high air content, such as powder, colloid, etc., with fast degassing rate and high automation degree. It is composed of belt conveyor, vacuum hood, vacuum pump, pneumatic lifting system, automatic detection and control system. Experiments can be done before use, and can be produced and used only after verification.

A pipe is installed on the vacuum box to connect with the vacuum pump. The model of the pump depends on the required vacuum degree (the vacuum degree is not less than 53kpa). Before the test, first brush the soapy water in the test area, then put the box on, turn on the pump, and see whether there is soap bubble in the box from the glass surface. The size of vacuum box is mostly 750mm × 300mm, It is a bottomless rectangular test box. There are sponge foam plastics around the bottom of the box. The top view mirror (plexiglass) is used. Before the test begins, the vacuum box is applied to the weld line and the soap solution is coated on the weld bead. When the air is drawn out of the weld box, the air will wake up when there are penetrating cracks, penetrating pores and other welding defects in the weld. Through the welding defects, soap bubbles will be produced. Determine the welding defects and draw obvious marks for repair.

The vacuum box is widely used in the vacuum storage of electronic and electrical products, such as semiconductor, electronic, electrical components, wafer, chemical raw materials, metallurgical powder, etc. it has the functions of moisture-proof, anti oxidation and discoloration, and has a good application in the process of vacuum rubber filling and bubble elimination.
