Figures 1-3 As shown, the device includes a conveyor 1, a controller 2, a laser marking machine 3, a sliding cylinder 4, a sliding block 5, a connecting frame 6, a centering block 7, and a positioning assembly. The conveyor 1 serves as the battery transport carrier, and the laser marking machine 3 is fixedly mounted on its top right side via bolts, responsible for performing the marking task. The controller 2 is located on the front right side, serving as the control core of the entire device and enabling coordinated control of all components. Sliding cylinders 4 are symmetrically mounted on the front and back of the conveyor 1 via bolts, and sliding blocks 5 are slidably connected to the sliding cylinders 4. A connecting frame is welded to the top of the sliding blocks 5. 6. Centering blocks 7 are connected to the inner sides of both connecting frames 6, and the centering blocks 7 are located on the front and rear sides of the conveyor roller of the conveyor 1. They are used to center and limit the battery on the conveyor roller. In order to prevent damage to the outer wall of the battery during the centering and limiting process, a buffer pad is fixed on the side of the two centering blocks 7 that are close to each other by adhesive. The buffer pad effectively buffers the pressure generated when the centering blocks 7 come into contact with the battery. The conveyor 1, the laser marking machine 3 and the slide cylinder 4 are all electrically connected to the controller 2 through the circuit and receive the instructions of the controller 2. The conveyor 1 is equipped with a positioning component.

The adjusting block 10 is threaded onto the screw 9. The adjusting block 10 abuts against the outer wall of the conveyor 1. Under the limiting action of the wall of the conveyor 1, the adjusting block 10 can only move along the axial direction of the screw 9 and cannot rotate around the axis. The motor 11 is bolted to the top of the adjusting block 10. The rotating plate 12 is connected to the output shaft of the motor 11. The two rotating plates 12 are longitudinally distributed above the conveyor roller of the conveyor 1, forming a positioning baffle for the battery. The motor 11 is electrically connected to the controller 2.

[0021] When laser marking the battery, first place the battery on the conveying roller of the conveyor 1, start the conveyor 1 to convey the battery to the left one by one, when the battery moves to abut against the rotating plate 12, it indicates that the battery has reached the designated marking position, at this time the controller 2 automatically pauses the conveyor 1 according to the preset program, and simultaneously starts the sliding table cylinder 4, which drives the sliding block 5, the connecting frame 6 and the centering block 7 to move inward, and the battery is accurately centered and limited by the centering block 7, after limiting, the laser marker 3 starts to mark the top surface of the battery according to the preset marking pattern or mark, after marking, the controller 2 controls the sliding table cylinder 4 to reverse and drive the sliding block 5, the connecting frame 6 and the centering block 7 to move outward to reset; at the same time, the controller 2 starts the motor 11, the output shaft of the motor 11 rotates to drive the rotating plate 12 to rotate outward to open and release the block of the battery, and the conveyor 1 starts to continue conveying the battery. Once the battery is conveyed away from the positioning position, the motor 11 automatically reverses to drive the rotating plate 12 to reverse and reset, waiting for the conveying of the next battery, so that through the cooperation of the rotating plate 12 and the centering block 7, the battery can be moved to the accurate position every time, and the marking accuracy is ensured. For batteries of different lengths and different marking position requirements, the horizontal position of the rotating plate 12 can be adjusted by rotating the screw rod 9, and in specific operation, a special tool is used to rotate the screw rod 9, the rotary motion of the screw rod 9 is converted into the linear motion of the adjusting block 10, and then the motor 11 and the rotating plate 12 are driven to move left and right along the horizontal direction, realizing the adaptive adjustment of different length batteries and ensuring the accuracy of the marking position.
