Specifically, the frame 1 includes a switch box 24, which contains an emergency stop switch 25, a power switch 26, a laser switch 27, and a galvanometer switch 28, allowing manual operation of the laser marking machine. The laser marking machine is connected to the PLC via signal transmission, and the marking is controlled by the PLC. Specifically, the Z-axis adjustment device 2 includes an adjustment disc 32, which is manually cranked... The adjusting disc 32 drives the screw inside the Z-axis adjusting device 2 to rotate, thereby driving the laser marking machine to move up and down to achieve vertical adjustment. A display screen 4 is provided on one side of the Z-axis adjusting device 2. Specifically, the frame 1 is equipped with a drawer 21, a first safety door 22, and a second safety door 23. The drawer 21 is used to place the keyboard. Opening the first safety door 22 allows the computer host to be placed inside the frame 1. The second safety door 23 facilitates the installation and maintenance of the control circuit board. A marking conveyor line 5 is provided below the marking machine body 3. The marking conveyor line 5 includes a conveyor line body 6, a lifting cylinder 7, a fixture plate 8, a first positioning cylinder 9, a first positioning plate 10, a second positioning cylinder, and a second positioning plate 12. The conveyor line body 6 is mounted on the frame 1. The conveyor body 6 includes a conveyor frame 1, a drive pulley and a driven pulley, and a belt 33 that drives the transmission on the pulleys. This belt can be a flat belt or a round belt, depending on the selected pulley. The drive pulley is driven by a motor controlled by a PLC. The battery body 11 is placed on the upper surface of the belt 33, and the motor drives the battery body 11 towards the fixture plate 8. After marking, the conveyor continues to unload. The lifting cylinder 7 is mounted on the frame 1 and located inside the conveyor body 6. The fixture plate 8 is mounted on the output end of the lifting cylinder 7. The cylinder is connected to an external air source and is equipped with a magnetic switch, controlled by a PLC for start and stop. The fixture plate 8 is equipped with a sensor, which can be a fiber optic sensor, to detect the arrival of the battery body 11. The first positioning cylinder 9 is located on the right side of the fixture plate 8 and is connected to the conveyor body 6. The first positioning plate 10 is connected to the output end of the first positioning cylinder 9. The second positioning cylinder is connected to the bottom of the feed side of the fixture plate 8, and the second positioning plate 12 is connected to the output end of the second positioning cylinder. When the sensor detects that the battery body 11 is in position, it sends a feedback signal, and the PLC controls the lifting cylinder 7 to lift the battery body 11 off the surface of the belt 33. Specifically, the fixture plate 8 includes a supporting ridge 13, a long side limiting edge 14, and a short side limiting edge 15. The short side limiting edge 15 is located at the rear end of the fixture plate 8, and the long side limiting edge 14 is located on the left side of the fixture plate 8.The fixture plate 8 is provided with a clearance groove 16 and a sensor mounting hole 17. The sensor is connected to the sensor mounting hole 17. The fixture plate 8 is provided with a notch 18 to avoid clearance with the second positioning plate 12. The support ridge 13, long side limiting edge 14, and short side limiting edge 15 of the frame 1 are coated with Teflon to prevent scratching the battery body 11. During debugging, the lifting cylinder 7 lifts the fixture plate 8, and the battery body 11 is manually placed on the fixture plate 8. The first positioning cylinder 9 and the second positioning cylinder are driven to extend and position the marking machine. The marking position of the marking machine is adjusted. During operation: the battery body 11 is manually placed on the belt 3 of the conveyor body 6. On the upper surface, the PLC-controlled conveyor body 6 transports the battery body 11 to the fixture plate 8. After the sensor detects the positioning, it sends a feedback signal, and the PLC-controlled conveyor body 6 stops. The lifting cylinder 7 then lifts the fixture plate 8. The first and second positioning cylinders then position the battery body 11. After laser marking, the first and second positioning cylinders reset, and the lifting cylinder 7 resets, returning the battery body 11 to the conveyor body 6. The conveyor body 6 continues to transport and unload the battery body 11. This process enables precise marking of the battery body 11, with high repeatability, good product consistency, and improved efficiency.
