AI Technical Summary
During the bonding process between the roof panel and the body beam, the pressure blocks of the existing pre-compression device are prone to shaking and falling, which poses a safety risk and affects the bonding efficiency.
Design a pre-compression protective fixture, including a protective body and a connecting part. The fixture is set with an acute angle to form an opening structure with the side of the pre-compression device to intercept falling pressure blocks, avoid injury to operators, and improve bonding efficiency.
It effectively prevents the pressure blocks from falling and injuring operators, and improves the safety and efficiency of the adhesive bonding between the top plate and the crossbeam.
