[0020] As shown in FIGS. 1 to 12, the multi-faceted automatic inkjet printing method for a driving lithium-ion battery according to the present invention includes: S1: An operator sets the driving lithium-ion battery to be inkjet printed on the clamp 80. At this time, the inkjet printing surface of the driving lithium-ion battery is placed upward; S2: The operator places the clamp 80 holding the driving lithium-ion battery to be inkjet printed into the inkjet printing equipment from the loading port; S3: The feeding module installed in the inkjet printing equipment conveys the clamp 80 to the inkjet printing station; S4: The lifting module installed in the inkjet printing equipment pushes up the clamp 80 at the inkjet printing station, and in order to adjust the distance between the inkjet printing surface of the driving lithium-ion battery and the inkjet printing module, it cooperates with the detection module to control the lifting stroke of the clamp 80; S5: The inkjet printing module inkjet prints on the inkjet printing surface of the driving lithium-ion battery; S6: The feeding module conveys the inkjet printed driving lithium-ion battery to the curing station; S7: The lifting module installed in the inkjet printing equipment pushes up the clamp 80 at the curing station, and in order to adjust the distance between the driving lithium-ion battery and the curing module, it cooperates with the detection module to control the lifting stroke of the clamp 80; S8: The curing module dries the target surface of the driving lithium-ion battery inkjet printed in S5; S9: The feeding module conveys the dried driving lithium-ion battery to the end of the feeding module; S10: The circulation module at the end of the feeding module conveys the clamp 80 to the return module; S11: The return module conveys the clamp 80 to the loading port; S12: The operator takes out the clamp 80 and takes out the driving lithium-ion battery set on the clamp 80, or turns the driving lithium-ion battery over and performs inkjet printing again.An operator holds, turns over, and removes the drive lithium-ion battery, sets or removes the drive lithium-ion battery at the loading entrance, and performs inkjet printing on the drive lithium-ion battery with an inkjet printing device, so that an insulating layer is uniformly coated on the outer surface of the drive lithium-ion battery. Thereby, the shell of the drive lithium-ion battery is efficiently covered with the insulating layer, and the risk of the battery shell being exposed during the transportation, storage, and use of the drive lithium-ion battery can be avoided.

[0021] Specifically, the clamp 80 includes a bottom plate, and a bent block module 86 for fixing a lithium-ion battery is provided on the bottom plate. The bent block module 86 includes a plurality of blocks, and each block is provided with a receiving groove 85 for contacting the lithium-ion battery.

When inkjet printing on the surface with the largest area of the driving lithium-ion battery 90, it is necessary to set the driving lithium-ion battery 90 horizontally. When setting the driving lithium-ion battery 90, the driving lithium-ion battery 90 is located above the clamp 80 and slowly moves downward to be set. During this process, until the lower surface of the driving lithium-ion battery 90 contacts the anti-scratch ball 84 provided on the first contact surface 81 at the bottom of the receiving groove 85, the side surface of the driving lithium-ion battery 90 contacts the anti-scratch ball 84 provided on the second contact surface 82, and the upper surface of the driving lithium-ion battery 90 contacts the anti-scratch ball 84 provided on the third contact surface 83.

When taking it out, by preventing scratches in the same way, it is possible to prevent the shell of the driving lithium-ion battery 90 from being scratched and improve the yield of the driving lithium-ion battery 90. When inkjet printing is performed on other surfaces of the driving lithium-ion battery 90, the driving lithium-ion battery 90 is set and fixed in the same manner.
