The feeding assembly 1 conveys the battery wafers 100 to the centering assembly 2. After the centering assembly 2 makes centering adjustments to the positions of the battery wafers 100, the battery wafers 100 are conveyed to the loading and feeding assembly 3. The lifting unit 302 of the loading and feeding assembly 3 jacks up the adsorption platform 303, and at the same time, the adsorption platform 303 adsorbs and fixes the battery wafers 100. By providing a feeding module 30 connecting the rotating unit 31 and the position adjusting unit 32, the rotating unit 31 and the position adjusting unit 32 are used to adjust the angles and spacings of the battery wafers 100. Then, the first transfer assembly 4 transfers multiple groups of battery wafers 100 together to the accommodation position 520 provided on the workbench 5. The rotating mechanism 51 drives the tabletop 52 to rotate by one accommodation position 520. The battery wafers 100 located at the accommodation position 520 are first photographed by the vision mechanism 10 to obtain accurate position information, and then the exposure device 9 performs an exposure operation on the battery wafers 100. After the exposure is completed, the battery wafers 100 rotate to a position close to the discharging assembly 8 on the workbench 5, and the discharging and feeding are completed through the discharging and feeding assembly 7. The discharging and feeding steps are the same as those of the loading and feeding, which will not be elaborated here. The prepared battery wafers 100 are transported to the discharging assembly 8 through the discharging and feeding assembly 7, and finally discharged through the discharging port at the end of the second transmission structure.
