[0002] Lithium-ion batteries, as a new type of green energy, are finding increasingly wider applications. In recent years, the demand for lithium-ion batteries has been rising continuously, and they are widely used in electric bicycles, electric vehicles, and military defense. In the lithium battery manufacturing process, surface printing is an essential step. Lithium battery printing is a means of identifying batteries and improving product appearance; different companies have their own naming conventions or codes. The methods and equipment for multi-sided battery printing have a significant impact on product quality throughout the entire lithium-ion battery production process. However, existing lithium battery printing equipment generally only allows for horizontal or vertical printing, and cannot achieve simultaneous horizontal and vertical printing, limiting its applicability. Summary of the Invention

Two sets of linear motors are arranged parallel to each other on the upper surface of the product platform.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] refer to Figure 1-Figure 3 This invention discloses a multi-faceted inkjet printing device for polymer lithium-ion batteries, comprising a product platform 1. Adjustable support legs 11 are provided at the four corners of the bottom of the product platform 1 to ensure a flat surface. Two sets of linear motors 2 are fixedly mounted parallel to each other on the upper surface of the product platform 1 using screws. A lithium battery 9 can be placed between the guide rails of the two sets of linear motors 2 for clamping and positioning, facilitating inkjet printing operations on the lithium battery 9. Two sliders 21 are fixedly mounted on the bottom surface of the guide rail of one set of linear motors 2. A groove 12 is formed on the upper surface of the product platform 1 to cooperate with the sliders 21. The linear motor 2 with the sliders 21 mounted can slide along the groove 12, thereby adjusting the distance between the guide rails of the two sets of linear motors 2 to achieve the purpose of clamping and positioning lithium batteries 9 of different sizes.

[0019] Two linear motors 2 are vertically fixed with brackets 3 on their sliding parts. A lead screw 4 is horizontally positioned between the two brackets 3. The lead screw 4 includes a hollow first screw 41 and a second screw 42 inserted into the first screw 41. When the guide rail of the linear motor 2 moves along the slide groove 12, the bracket 3 on it also moves accordingly, and the lead screw 4 extends and retracts. The two ends of the first screw 41 and the second screw 42 are rotatably connected to the brackets 3. One end of the first screw 41, rotatably connected to the bracket 3, passes through the bracket 3 and is coaxially fixed to a reduction motor 43. At the same time, a limit groove 411 is formed on the inner side wall of the first screw 41 along its own length direction. A limit block 421 is fixedly provided on the side wall of the second screw 42, which is inserted into the first screw 41. The limit block 421 is slidably connected in the limit groove 411. By setting the limit block 421 and the limit groove 411, the rotation of the lead screw 4 can be achieved. A slide rail 5 is horizontally arranged between the two supports 3, and the slide rail 5 is fixedly connected to the supports 3. The slide rail 5 includes a hollow first slide rail 51 and a second slide rail 52 inserted inside the first slide rail 51. When the guide rail of the linear motor 2 moves along the slide groove 12, the slide rail 5 will also extend or retract.

[0020] A mounting plate 7 is installed on the lead screw 4 and the slide rail 5. The mounting plate 7 has threaded holes and through holes. The mounting plate 7 is threaded into the lead screw 4 through the threaded holes and slidably engaged with the slide rail 5 through the through holes. A coding machine 8 is fixedly mounted on the side wall of the mounting plate 7, with the nozzle of the coding machine 8 facing downwards. A threaded sleeve 6 is threaded onto the second screw 42, and a first elastic layer is wrapped around the outer side wall of the threaded sleeve 6. A second elastic layer is fixedly mounted on the through-hole side wall of the mounting plate 7.

[0021] A PLC controller is installed inside the product platform 1. The upper surface of the product platform 1 is equipped with a touch screen 13 for setting parameters, as well as a power switch 14, a start switch 15, and a pause switch 16. The PLC controller is electrically connected to the inkjet printer 8, the geared motor 43, the linear motor 2, the touch screen 13, the power switch 14, the start switch 15, and the pause switch 16.

[0022] The implementation principle of the above embodiment is as follows: First, the linear motor 2 with the slider 21 is slidably installed so that the lithium battery 9 is just positioned between the two sets of linear motors 2. During this process, the lead screw 4 and the slide rail 5 will also extend and retract accordingly. After the lithium battery 9 is placed, the threaded sleeve 6 is rotated to move along the second screw 42 to the position where it intersects with the first screw 41. Then, the power switch 14 is turned on, the printing parameters are set through the touch screen 13, and the start switch 15 is pressed. The PLC controller will control the reduction motor 43 to work, so that the mounting plate 7 drives the inkjet printer 8 to slide along the lead screw 4 and the slide rail 5 to achieve horizontal printing of the inkjet printer 8. After the horizontal content is printed, the mounting plate 7 returns to its original position. Then, the PLC controller will control the linear motor 2 to work, so that the bracket 3 moves along the length direction of the guide rail of the linear motor 2, thereby driving the inkjet printer 8 to move vertically to achieve vertical printing of the inkjet printer 8. When the mounting plate 7 moves along the lead screw 4, when it reaches the junction of the first screw 41 and the second screw 42, it continues to move towards the second screw 42 under the action of the first screw 41. At this time, the threaded sleeve 6 is inserted into the threaded hole of the mounting plate 7 and, under the action of the first elastic layer, it is interference-fitted with the mounting plate 7. This causes the threaded sleeve 6 to move the mounting plate 7 along the second screw 42. When the mounting plate 7 needs to return to its original position, the reduction motor 43 rotates in the opposite direction. When the threaded sleeve 6 reaches the junction of the first screw 41 and the second screw 42, it separates from the mounting plate 7 under the action of the second screw 42, thus realizing the reciprocating motion of the mounting plate 7. When the mounting plate 7 moves along the slide rail 5, when it slides to the junction of the first slide rail 51 and the second slide rail 52, the second elastic layer inside the hole of the mounting plate 7 abuts against the second slide rail 52, allowing the mounting plate 7 to slide along the second slide rail 52. During operation, the process can be interrupted by the pause switch 16.

[0023] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
