PURPOSE/DESCRIPTION OF PROCESS

Automotive glass laminated glass processing line, the curved laminated glasses after the bending process, inner and outer glasses sheet need to be “sandwiched”.

A typical automobile windshield is a compound pane, made of two thin glass sheets, the inner glass (the one on the inside of the car) and the outer glass, joined together by a special plastic inter layer made of Polyvinyl Butyral, or PVB.

The process description as below,
Put the first glass which need to be laying the PVB film on into the PVB assembly,
Suck up the upper PVB film with a vacuum suction cup,
Put the PVB film on the first glass sheet,
Put down the second sheet, upper glass, and cut off the excess PVB film edge material. Because the two sides of float glass are different, one side is in contact with the tin in the tin bath and the other side is in contact with the ammonia gas during the production process, which we usually call the tin side and the air side. The adhesive force between the air side of the glass and PVB is stronger than that of the tin side and PVB. Therefore, in the production, the air side of the outer sheet faces inward, and the air side of the inner sheet faces outward. Only in this way can the two air surfaces be in contact with the PVB.

This operation needs to be carried out in a special environment, clean room is required. and the autonomous air conditioning system can ensure the constant temperature and humidity conditions of the PVB sheet.

Laminated glass is a safety glass made by sandwiching PVB film between two or more pieces of glass and then firmly combining with high temperature and high pressure. Laminated glass is widely used in automobile and bulletproof fields. The laminated glass production line is usually composed of a glass washing and drying machine, PVB Assembly line, a fully automatic walking suction cup or robot, a PVB film laying system, a transition conveyor, preheating and prepressing. The whole line adopts PLC centralized control, with high production efficiency and yield, easy operation, safe and reliable. According to customer requirements, automatic online with different configurations can be realized.

Automation level can be customized,
Manual PVB Assembly line
Semi-automation
Full automation with robot

APPLICATION

Automobile glass laminating production line.

Such as front windshield glass, sunroof glass, laminated sidelites, laminated window glass, door glass.

ADVANTAGES

● The glass transmission conveyor adopts adjustable belt, high quality belt, ensure no marks on the glass.
● During the transition between 4 to 6 sections continuous conveyor belts, the glass is transferred smoothly.
● With adjustable production speed, which is available with equipment before and after, such as bent glass washing machine and automotive De-airing system.
● All parts adopt anti-rust treatments to avoid contaminating in the laminating room.
● Lifting up system at the PVB laying up station and vacuum ring process station, easy for the manual operation.
● An automatic glass loading system, operator don’t need to the manual handling the Outer glass above the inner in the windshield assembly after putting the PVB material on the inner glass sheet.
● Each glass transmission line is equipped with sensors, which can detect the position of the glass for the control.
