[0002] In modern industrial production, plates and strips are widely used. With the continuous advancement of science and technology and the increasing requirements for product quality and performance, plate and strip welding technology is also facing higher challenges. Traditional welding methods have certain limitations in plate and strip welding, and the emergence of laser welding technology has brought new breakthroughs in plate and strip welding. The existing plate and strip laser welding device is usually composed of structures such as a conveying device, a welding device and a shearing device. When in use, the plate and strip are placed on the conveying device, and then the conveying device sends the plate and strip to the welding position for shearing, and then the sheared plate and strip are welded, and the sheared waste is collected from the waste conveying device on the lower side of the shearing device into the material box. However, since the plate and strip cannot automatically complete the above processes during the conveying, shearing and welding process, the production auxiliary time is increased, resulting in high labor intensity and dangerous procedures in the operation process, which greatly reduces the production rhythm and efficiency. In order to solve the shortcomings of the existing technology, we propose a plate and strip laser welding device. Utility Model Content

[0007] The centering mechanism and the two-point centering device in the clamping mechanism together form a four-point centering to ensure the consistency of the centering of the belt head and tail.

[0021] The driving wheel 32 is driven to rotate by starting the motor 31 , and the driving wheel 32 rotates to drive the driven wheel 35 to rotate synchronously through the conveying chain 33 , thereby driving the conveying chain 33 to move in the lower inner cavity of the double-edged shear mechanism 2 .

[0022] Among them, the centering mechanism 10 and the two-point centering device in the clamping mechanism 7 together form a four-point centering to ensure the consistency of the centering of the belt head and tail;

[0023] The positioning and alignment of the leader is completed by arranging the equipment in a direction perpendicular to the center line of the unit.

[0024] The pusher plate arranged on the outer wall of the conveying chain 33 slides on the sliding groove surface of the double-edged shear mechanism 2 .

[0028] First, the device is placed at the entrance end of the plate and strip production unit, and then the device is started, and the tail of the plate and strip is pressed down and rotated to the shearing position through the clamping roller mechanism 9 at the welding machine outlet. At this time, the sleeve roller mechanism 11 is lifted to form an arch sleeve, and the head of the plate and strip reaches the clamping roller mechanism 9 at the entrance of the welding machine. The clamping roller mechanism 9 works to drive the clamping roller to rotate and transport the head to the shearing position. At this time, the sleeve roller mechanism 11 is lifted to form an arch sleeve, and then the entrance / exit clamp mechanism 7 is lowered to the preparation position, and the lateral pressure wheel presses the plate and strip, and then the clamping roller mechanism 9 is opened to align the plate and strip at four points through the centering mechanism 10, and then the entrance / exit clamp mechanism 7 works to press the head.
