[0002] The anti-collision beam is located at the front and rear ends of the car and is a protective device for the front and rear of the car body. It is a device used to absorb collision energy when the vehicle is hit. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at low speeds, minimizing the damage to the longitudinal beams of the car body caused by the impact force, thereby playing a protective role for the vehicle. Anti-collision beams generally require laser welding during production. In automated laser welding production lines, welding fixtures are required to fix the anti-collision beams. The anti-collision beams also need to be flipped during the welding process.
