Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to a coding device for lithium battery testing. Background Technology

[0002] Lithium battery inkjet printing involves printing information about the battery onto its outer casing, essentially giving the battery an "identity card." The inkjet printing content for lithium-ion batteries includes the manufacturer, model number, production date, voltage, capacity, energy, production batch number, and a QR code. Lithium battery inkjet printing factories must prioritize quality during the printing process. Whether printing on lithium batteries or other types of batteries, misaligned, duplicate, or broken printing must be removed. Defective products must not be mixed together; they must be clearly identified and reworked promptly.

[0003] In the lithium battery production process, battery testing and labeling are critical steps. Currently, most manufacturers use a step-by-step approach, that is, to test the battery first and then mark it with inkjet printing. This method is not only time-consuming but also prone to errors.

[0004] Existing technologies, such as the utility model patent with publication number CN221213159U, describe an integrated testing and coding machine for lithium battery production. This machine includes a frame assembly, a feeding assembly mounted on the frame assembly for arranging lithium batteries, a conveying assembly connected to the discharge port of the feeding assembly for transporting lithium batteries, a recycling assembly mounted on one side of the conveying assembly for recycling defective lithium batteries, and a control assembly mounted on the frame for controlling equipment operation. Above the conveying assembly is a positioning coding assembly for testing and coding lithium batteries. By providing a V-shaped positioning block above the conveying assembly, the V-shaped positioning block effectively positions and fixes the lithium batteries when coding is required. Furthermore, the printhead is positioned on the V-shaped surface of the V-shaped positioning block, ensuring that even vibrations do not affect the coding effect and prevent blurry coding. By installing the testing probe and the V-shaped positioning block in the same position, testing and coding operations can be performed simultaneously, thereby improving production efficiency.

[0005] The device positions and fixes the battery using a V-shaped positioning block, but the fixing method is unidirectional, which may cause the battery to rotate, resulting in blurred inkjet printing.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a coding device for lithium battery testing that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted: a coding device for lithium battery testing, comprising: a frame and a positioning mechanism for positioning lithium batteries;

[0009] The positioning mechanism includes: a pressure block, on which slots are evenly provided, and an inkjet printer is slidably installed in the slots. The inkjet printer is fixedly installed on a mounting plate. A push rod of an electric actuator is fixedly connected to the bottom of the mounting plate, and the electric actuator is fixedly installed on the pressure block. A support plate is fixedly installed on the mounting plate, and an elastic element is fixedly installed between the support plates.

[0010] Furthermore, the pressure block is slidably mounted on the fixed rod, and the fixed rod is fixedly mounted on the fixed frame.

[0011] Furthermore, a spring is fitted onto the fixing rod, and the two ends of the spring are fixedly connected to the pressure block and the fixing frame.

[0012] Furthermore, the length of the groove is less than the length of the lithium battery.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a coding device for lithium battery testing, in which the push rod of the electric push rod drives the mounting plate to descend, so that the elastic element contacts both ends of the lithium battery and deforms, thereby increasing the frictional resistance between the elastic element and the lithium battery, preventing the lithium battery from rotating and thus avoiding blurry coding.

[0024] like Figures 1 to 6As shown, this utility model discloses a lithium battery testing inkjet printing device, comprising: a frame 1, a conveying device 5 for conveying lithium batteries, a feeding device 2 located at one end of the conveying device 5, a testing device 3 and a sorting device 4 located on both sides of the conveying device 5, and a positioning mechanism 6 for positioning lithium batteries; a battery holder 65 is installed on the conveying device 5, the top of the battery holder 65 is arc-shaped to facilitate the holding and conveying of lithium batteries. The feeding device 2 feeds the lithium batteries onto the battery holder 65, and the conveying device 5 drives the battery holder 65 to convey the lithium batteries to the position of the testing device 3, so that the lithium batteries are located below the positioning mechanism 6. The testing device 3 aligns the two ends of the battery in the center and performs testing. Then, the positioning device positions and fixes the lithium batteries to prevent them from rotating during inkjet printing. After testing, the sorting device 4 removes unqualified lithium batteries.

[0025] The positioning mechanism 6 includes: a pressure block 64, which is slidably mounted on a fixed rod 62 and located above the battery holder 65. The fixed rod 62 is fixedly mounted on a fixed frame 61, which is fixedly mounted on the top of the frame 1. The support feet of the fixed frame 61 are located on both sides of the conveying device 5. A spring 63 is sleeved on the fixed rod 62, and the two ends of the spring 63 are fixedly connected to the pressure block 64 and the fixed frame 61. The spring 63 pushes the pressure block 64 to press against the battery, so that the pressure block 64 presses the battery tightly, preventing the battery from detaching from the battery holder 65 during detection and coding. The battery is provided with uniformly spaced slots, the width of which is less than the diameter of the battery. A coding inkjet printer 613 is slidably installed in the slots, with the coding nozzle 610 of the inkjet printer 613 located at its bottom and facing vertically downwards. When coding the lithium battery, the edge of the coding nozzle 610 contacts the lithium battery to ensure coding stability. The inkjet printer 613 is fixedly installed on the mounting plate 69, and the bottom of the mounting plate 69 is fixedly connected to the push rod of the electric push rod 612. The electric push rod 612 is fixedly installed on the pressure block 64. Support plates 615 are uniformly installed on the mounting plate 69, and elastic members 611 are installed between the support plates 615.

[0026] Furthermore, the bottom of the elastic element 611 is lower than the position of the inkjet nozzle 610 of the inkjet printer 613, so that the bottom of the elastic element 611 can contact the lithium battery before the inkjet nozzle 610.

[0027] Furthermore, the elastic element 611 is square, and its width is the same as the length of the support plate 615. The surface of the elastic element 611 is made of a rubber material with good elasticity, while the interior of the elastic element 611 is filled with sponge. The support plate 615 fixes and limits the elastic element 611, preventing it from bending and thus preventing it from securing the lithium battery. The elastic element 611 is aligned with both ends of the lithium battery. When the mounting plate 69 lowers the elastic element 611, the bottom of the elastic element 611 contacts both ends of the lithium battery, causing it to deform and trap the lithium battery within it. The surface of the lithium battery adheres tightly to the surface of the elastic element 611, increasing the resistance encountered during the rotation of the lithium battery and preventing it from rotating during coding. It also reduces the clamping force on the lithium battery, preventing deformation caused by excessive clamping force.

[0028] When the conveying device 5 conveys the lithium battery to the bottom of the pressure block 64 through the battery holder 65, and the battery holder 65 is aligned with the inkjet printer 613, the detection probe in the detection device 3 contacts both ends of the lithium battery. During the detection time, the lithium battery is pushed to the center position, and the push rod of the electric push rod 612 drives the mounting plate 69 to descend. The mounting plate 69 drives the inkjet printer 613 and the elastic member 611 to descend. The elastic member 611 first contacts both ends of the lithium battery. When the edge of the inkjet nozzle 610 of the inkjet printer 13 contacts the lithium battery, the elastic member 611 deforms and adheres tightly to the surface of the lithium battery. Then, the inkjet printer 613 prints the lithium battery.

[0029] A support frame 68 is fixedly installed on the top of the fixed frame 61. A liquid storage tank 66 is fixedly installed on the support frame 68. An inlet 67 is provided on the top of the liquid storage tank 66. Ink is added to the liquid storage tank 66 through the inlet 67. A liquid inlet pipe 614 is connected to the bottom of the liquid storage tank 66. The other end of the liquid inlet pipe 614 is connected to the inkjet printer 613. The ink in the liquid storage tank 66 is delivered to the inkjet printer 613 by gravity through the liquid inlet pipe 614.

[0030] Working principle:

[0031] When the mounting plate 9 is lowered by the push rod of the electric push rod 612, the mounting plate 69 drives the elastic element 611 and the inkjet printer 613 to lower. On the one hand, the elastic element 611 first contacts the lithium battery and causes the lithium battery to be embedded in the elastic element 611, thereby causing the elastic element 611 to obstruct the rotation of the lithium battery and prevent the lithium battery from rotating during the inkjet printing process. On the other hand, the lithium battery is clamped and fixed by the elastic element 11 and the battery holder 65, which can prevent the lithium battery from deforming due to excessive clamping force, improve the clamping firmness, and prevent the lithium battery from moving.
