Description

Technical Field

[0001] This utility model relates to the field of lithium battery printing equipment, and in particular to a multi-sided printing device for lithium batteries. Background Technology

[0002] In the processing of the insulating layer of lithium batteries, in order to ensure the shear strength and insulation of the insulating layer, it is generally necessary to print on multiple sides of the outer surface to ensure the stability of the lithium battery performance.

[0003] Existing printing equipment typically uses a single printing mechanism to print on one side, such as Chinese Patent 202311268812.X. In order to achieve multi-sided printing of the insulation layer and overall printing, the production line is long and the equipment is also large.

[0004] Generally, there are at least five processes, so the overall length is also relatively long. At the same time, the total printing time for a single lithium battery will also be relatively long, which affects the processing efficiency. Summary of the Invention

[0005] The main purpose of this invention is to propose a multi-sided printing device for lithium batteries, which aims to improve existing lithium battery printing equipment, enabling high-speed and high-efficiency printing. At the same time, the design of each structural module reduces the length of the device, thereby making it suitable for lithium batteries of different sizes while improving processing efficiency.

[0006] To achieve the above objectives, this utility model proposes a multi-sided printing device for lithium batteries, comprising:

[0007] A transport device, the transport device being equipped with a fixture for holding a lithium battery to be printed;

[0008] A top printing module is disposed on a transport device and is used to print UV insulating ink on the bottom surface of a lithium battery.

[0009] Side printing modules, wherein two side printing modules are provided and arranged opposite each other and respectively located on both sides of the transport device, the side printing modules are used to print UV insulating ink on the sides of lithium batteries;

[0010] The side printing module is provided with at least one set;

[0011] A curing module for curing UV insulating ink onto the wall of a lithium battery.

[0012] In the actual design, by modularizing the various mechanisms and enabling simultaneous printing of UV insulating ink on both sides of the printing device, the actual length of the printing device is shorter. Simultaneous printing on both sidewalls can effectively shorten the printing time and improve the printing efficiency and turnover rate of lithium batteries.

[0013] Synchronizing the lithium battery and printing equipment at the same rate can effectively improve processing accuracy and efficiency, ensure the cycle time of spacing processing, and increase the turnover rate of the equipment. Attached Figure Description

[0035] like Figures 1 to 11 As shown, a multi-sided printing device for lithium batteries includes a printing device.

[0036] The printing device includes:

[0037] The transport device 1 is equipped with a fixture 10, which is used to place the lithium battery 11 to be printed.

[0038] Top printing module 2, which is disposed on the transport device 1, is used to print UV insulating ink on the bottom surface of the lithium battery 11.

[0039] Side printing modules are provided in two opposite positions and located on both sides of the transport device 1. The side printing modules are used to print UV insulating ink on the sides of the lithium battery 11.

[0040] The side printing module is provided with at least one set;

[0041] A curing module is used to cure UV insulating ink onto the wall surface of the lithium battery 11;

[0042] Printing method using printing equipment:

[0043] S1: The lithium battery 11 to be printed is placed in the fixture 10 by manual labor or a robotic arm;

[0044] S2: The transport device 1 moves the fixture 10 to the top printing module 2, and then the top printing module 2 prints insulating ink on the bottom surface of the non-electrical terminals of the lithium battery 11.

[0045] S3: When the bottom surface printing is completed, the transport device 1 moves the lithium battery 11 to the side printing module, which can print on the two or four opposite sides of the lithium battery 11.

[0046] S4: After the side of the lithium battery 11 is printed, the transport device 1 moves the lithium battery 11 with the printed insulating ink to the curing module and cures the UV insulating ink.

[0047] S5: The transport device 1 drives the lithium battery 11 to print at least two insulating layers in a predetermined direction.

[0048] In the actual design, by modularizing the various mechanisms and enabling simultaneous printing of UV insulating ink on both sides of the printing device, the actual length of the printing device is shorter. Simultaneous printing of two side walls can effectively shorten the printing time and improve the printing efficiency and turnover rate of lithium battery 11.

[0049] Specifically, the transport device 1 drives the lithium battery 11 through the top printing module 2, the side printing module and the curing module in sequence at a predetermined speed. Unlike existing printing methods, which use a stop-printing method during operation, the constant-speed printing method can effectively improve the turnover rate and achieve orderly transportation, reducing the time gaps caused by stops.

[0050] In this embodiment of the invention, the end of S5 is further provided with a final curing module 5; a rotating device is provided between the transport device 1 and the fixture 10 (of course, the rotating device can also be a clamping device set at the loading position for flipping, wherein this application can reduce the process of clamping and flipping the lithium battery compared with the previous solution), the rotating device is used to drive the lithium battery 11 to rotate, and then the side printing module and the curing module respectively print insulating ink on the four sides of the lithium battery 11 and cure it, thereby completing the processing of the insulating surface of the lithium battery 11.

[0051] In this embodiment of the invention, a set of top printing module 2, side printing module and curing module is provided;

[0052] In S51, the transport device 1 drives the fixture 10 to move back and forth along its length.

[0053] In S51, the insulating ink surface has three layers;

[0054] During the first printing, the transport device 1 drives the fixture 10 to move in the positive direction, accelerating to 800mm / s with an acceleration of 5m / s², taking 0.16s; then it passes through 2040mm at a constant speed, completing the first printing and the first pre-curing, taking 2.55s; then it decelerates to 0 with a deceleration of 5m / s², taking 0.16s, for a total time of 2.87s;

[0055] During the second printing, the transport device 1 drives the fixture 10 to move in the opposite direction, accelerating to 800 mm / s with an acceleration of 5 m / s², taking 0.16 s; then it passes through 2040 mm at a constant speed, completing the first printing and first pre-curing, taking 2.55 s; subsequently, it decelerates to 0 with a deceleration of 5 m / s², taking 0.16 s, for a total time of 2.87 s;

[0056] During the third printing, the transport device 1 drives the fixture 10 to move in the positive direction, accelerating to 800mm / s with an acceleration of 5m / s², taking 0.16s. Then, it passes through 2040mm at a constant speed to complete the first printing and the first pre-curing, taking 2.55s. The total time is 2.71s. It continues to pass through the final curing at a speed of 800mm / s, and at the same time, it completes the printing of the three sides of the battery cell in 8.45s.

[0057] In this embodiment of the invention, when there are three sets of top printing module 2, side printing module and curing module;

[0058] In S52, the transport device 1 drives the fixture 10 to move unidirectionally along its length.

[0059] In step S52, the insulating ink surface has three layers.

[0060] The transport device 1 is driven to accelerate to 800 mm / s, with an acceleration of 5 m / s², taking 0.16 s; then it passes through 5000 mm at a constant speed, completing three printing and three pre-curing processes, taking 6.25 s; then it decelerates to 0, with a deceleration of 5 m / s², taking 0.16 s, for a total time of 6.57 s.

[0061] Specifically, let's compare the action flow of Option 2 and Option 1:

[0062] 1. Compared with Option 2, S51 saves two printing modules and one pre-curing module, which has a significant cost advantage;

[0063] Option 2, S52, has a shorter printing cycle, resulting in higher production capacity and faster efficiency.

[0064] In this embodiment of the invention, the side printing module of S51 is provided in two sets and is spaced apart, so printing on all four sides can be achieved even without a rotating device.

[0065] In this embodiment of the invention, the transport device 1 includes a horizontal drive rail 12, a horizontal drive slider 13 slidably mounted on the horizontal drive rail 12, and a horizontal lead screw pair 14 for driving the horizontal drive slider 13 to move.

[0066] The horizontal drive rail 12 has a closed-loop structure or a linear structure. The closed-loop structure can effectively reduce the loading and unloading of the fixture 10, thereby effectively improving the printing efficiency.

[0067] In this embodiment of the invention, the top printing module 2 includes a first gantry 20, a first transverse moving frame disposed on the first gantry, and a first printing device disposed on the first printing device. The printing surface of the first printing device is disposed downwards, and the first transverse moving frame can be adjusted in position according to different products, thereby improving the efficiency and applicability of top printing.

[0068] In this embodiment of the invention, the first transverse moving frame includes a first transverse guide rail 21 disposed on the top of the gantry frame, a first transverse slider 22 slidably mounted on the first transverse guide rail 21, and a first transverse lead screw pair 23 for driving the first transverse slider to move.

[0069] The side printing module includes a first longitudinal moving frame 31 and a first vertical moving frame 32 disposed on the first longitudinal moving frame 31. The first vertical moving frame 32 is provided with a second printing device. The printing surface of the printing device is vertically arranged and faces the direction of the transport device 1.

[0070] The first longitudinal moving frame 31 includes a first longitudinal guide rail 311, a longitudinal slider 312 slidably mounted on the longitudinal guide rail, and a longitudinal lead screw pair 313 for driving the longitudinal slider.

[0071] The first vertical moving frame 32 includes a vertical guide rail 321 disposed on the longitudinal slider, a vertical slider 322 slidably mounted on the vertical guide rail, and a vertical lead screw pair 323 for driving the vertical slider.

[0072] In this embodiment of the invention, the curing module and the final curing module 5 have the same structure, including a top ultraviolet device 41 and two side ultraviolet devices 42.

[0073] The side ultraviolet device can adjust its relative height and lateral position. Specifically, the side ultraviolet device includes a vertically arranged synchronous drive device, a vertical guide rail, a vertical slider, and a lateral adjustment track disposed on the vertical slider. The side ultraviolet device is disposed on the lateral adjustment track. The predetermined stroke can be adjusted manually or by using a rotary motor.

[0074] Specifically, by adjusting the position, the printing and curing of insulating ink surfaces on lithium batteries 11 of different sizes can be achieved, thereby improving the applicability of the equipment and reducing production costs.

[0075] The printing device is a digital printing device, and the printing device is provided with a plurality of nozzles.
