[0002] Lithium-ion batteries are widely used in various portable electronic devices and electric vehicles due to their high energy density, long cycle life, and environmental friendliness. Pouch batteries, a type of lithium-ion battery, are gradually becoming the mainstream in the market due to their flexibility, high safety performance, and ability to be flexibly designed.

[0003] Aluminum-plastic film is a key material for packaging soft-pack lithium battery cells. It is a high-strength, high-barrier, multi-layered composite material with excellent barrier properties, electrolyte stability, cold stamping formability, puncture resistance, and insulation, and it has extremely stringent technical requirements. During the production and application of soft-pack batteries, barcodes are printed on the surface of the aluminum-plastic film. These barcodes are significant, not only allowing users to quickly identify the materials used in the cell, its capacity, voltage, and manufacturer's batch number, but also linking process data from each step of the cell manufacturing process, achieving cell traceability.

[0004] However, in the coding process of pouch batteries, the special ink used by UV inkjet printers may cause poor coding results, such as garbled codes and blurred characters, when combined with the aluminum-plastic film on the surface of the pouch battery due to material compatibility issues or improper operation. Existing coding cleaning methods are difficult to effectively and thoroughly remove ink coding from the aluminum-plastic film surface of pouch batteries and are prone to damaging the aluminum-plastic film surface of the battery cells, causing many problems for battery manufacturers and users. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device for removing ink markings from the surface of batteries, so as to solve the problem that existing ink marking cleaning methods are difficult to effectively and thoroughly remove ink markings from the surface of the aluminum-plastic film of soft-pack batteries, and are prone to damaging the surface of the aluminum-plastic film of the battery cell.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1 to 3 As shown, a cleaning device for removing ink markings from the surface of a battery includes a base plate 100. A placement groove 110 is provided on the top of the base plate 100, and a battery 101 to be cleaned is placed in the placement groove 110. A side plate 102 is fixedly provided on one side of the top of the base plate 100. Two symmetrically arranged mounting plates 103 are provided on the side wall of the side plate 102 near the placement groove 110. A cleaning mechanism for removing ink markings from the surface of the battery 101 to be cleaned is provided between the mounting plates 103.

[0016] In this embodiment, the cleaning mechanism includes a rotating shaft 104 rotatably disposed between mounting plates 103. A motor 106 is fixedly mounted on the side wall of the mounting plate 103. The output end of the motor 106 is connected to one end of the rotating shaft 104. The other end of the rotating shaft 104 passes through the mounting plate 103 and is fixedly fitted with a first bevel gear 202. The end of the mounting plate 103 is connected to a mounting bracket 108 via a connecting rod 107. A cleaning roller 109 is rotatably mounted on the mounting bracket 108 near the placement groove 110, and a contact wheel 113 is fixedly mounted on the other side. A cam 105 is fixedly fitted on the shaft of the rotating shaft 104 to contact the contact wheel 113. Multiple mounting brackets are fixedly mounted on the mounting plate 103 and the mounting bracket 108. A fixed rod 111 is provided, and a spring 112 is provided between the fixed rods 111. A fixed plate 204 is fixedly provided on the end of the mounting frame 108 near the first bevel gear 202. A rotating rod 200 is rotatably provided between the fixed plate 204 and the side plate 102. A second bevel gear 203 that meshes with the first bevel gear 202 is fixedly sleeved on the rod of the rotating rod 200. The roller shaft of the cleaning roller 109 passes through the mounting frame 108 and is fixedly provided with a fourth bevel gear 206. A third bevel gear 205 that meshes with the fourth bevel gear 206 is rotatably provided on the fixed plate 204. A limiting block 201 is provided on the rod of the rotating rod 200. A limiting groove that matches the limiting block 201 is provided on the fixed plate 204.

[0017] When the motor 106 is started, the output end of the motor drives the rotating shaft 104 to start rotating. One end of the rotating shaft 104 is connected to the motor 106, and the other end is fixedly fitted with the first bevel gear 202. As the rotating shaft 104 rotates, the first bevel gear 202 will also start to rotate. The second bevel gear 203, which meshes with the first bevel gear 202, is located on the rotating rod 200. Therefore, the rotating rod 200 will rotate with the rotation of the first bevel gear 202. Since the rotating rod 200 is restricted to moving within a certain range by the limiting block 201 and the limiting groove, the stability and accuracy of the transmission are ensured. The roller shaft of the cleaning roller 109 passes through the mounting frame 108 and is fixedly fitted with the fourth bevel gear 206. The third bevel gear 205, which meshes with the fourth bevel gear 206, is located on the fixed plate 204. As the rotating rod 200 rotates, the third bevel gear 205 will drive the fourth bevel gear 206 and the cleaning roller 109 to rotate together. Meanwhile, a cam 105 is fixedly sleeved on the rotating shaft 104. As the rotating shaft 104 rotates, the cam 105 will periodically contact and push the contact wheel 113, causing the mounting bracket 108 to reciprocate under the action of the fixed rod 111 and the spring 112. As the cleaning roller 109 rotates and reciprocates, the cleaning agent will be evenly applied to the battery surface and remove ink printing through physical and chemical action, thereby enhancing the cleaning effect of the cleaning roller 109 on the battery surface. The contact force between the cleaning roller 109 and the battery surface is moderate to avoid damaging the surface of the aluminum-plastic film of the battery cell.

[0018] In this embodiment, the cleaning roller 109 is provided with a cleaning agent, the raw materials of which include dichloromethane, n-butanol, ethanol and n-pentane in a mass ratio of 1:1:1:7.

[0019] The cleaning agent contains dichloromethane, which has a small molecular weight and weak polarity, but a strong ability to penetrate large molecules and intersegmental gaps. This allows it to dissolve the paint film and disrupt its adhesion to the substrate, thus removing ink from the surface of the aluminum-plastic film. Butanol, as a hydrophobic solvent, reduces surface tension, protecting the surface of the aluminum-plastic film and preventing damage to its appearance during ink removal. Ethanol facilitates more thorough contact between reactants, accelerating the reaction rate. Pentane, as the main solvent, has weak polarity and strong solvent capacity and volatility, rapidly dissolving and evaporating the ink from the aluminum-plastic film surface without altering its appearance. The proportion of dichloromethane in the raw materials can be adjusted to 5-15%. This amount should not be too much, otherwise it will damage the surface appearance of the aluminum-plastic film. Dichloropropane and other reagents can be used instead. The proportion of n-butanol can be adjusted to 5-15%, and solvents such as n-propanol can be used instead. The proportion of ethanol can be adjusted to 5-15%, and solvents such as ethylene glycol can be used instead. The proportion of n-pentane can be adjusted to 55%-85%.

[0020] Example 1: The cleaning agent consists of 10% dichloromethane, 10% n-butanol, 10% ethanol and 70% n-pentane; the inkjet printing cleaning agent is prepared according to the above proportions; the inkjet printing area on the aluminum-plastic film surface is wiped.

[0021] Example 2: The cleaning agent consists of 10% dichloropropane, 10% n-butanol, 10% ethanol, and 70% n-pentane; the inkjet cleaning agent is prepared according to the above proportions; the inkjet-printed area on the aluminum-plastic film surface is wiped.

[0022] Example 3: The cleaning agent consists of 10% dichloromethane, 10% n-propanol, 10% ethanol, and 70% n-pentane; the inkjet cleaning agent is prepared according to the above proportions; the inkjet-printed area on the aluminum-plastic film surface is wiped.

[0023] Example 4: The cleaning agent consists of 10% dichloromethane, 10% n-butanol, 10% ethylene glycol, and 70% n-pentane; the inkjet printing cleaning agent is prepared according to the above proportions; the inkjet printing area on the aluminum-plastic film surface is wiped.

[0024] Example 5: The cleaning agent consists of 5% dichloromethane, 5% n-butanol, 5% ethanol, and 85% n-pentane; the inkjet printing cleaning agent is prepared according to the above proportions; the inkjet printing area on the aluminum-plastic film surface is wiped.

[0025] Comparative Example 1: The cleaning agent consisted of 10% n-butanol, 10% ethanol, and 80% n-pentane; the inkjet cleaning agent was prepared according to the above proportions; and the inkjet-printed area on the aluminum-plastic film surface was wiped.

[0026] Comparative Example 2: The cleaning agent consisted of 10% dichloromethane, 10% n-butanol, and 80% n-pentane; the inkjet cleaning agent was prepared according to the above proportions; and the inkjet-printed area on the aluminum-plastic film surface was wiped.

[0027] Comparative Example 3: The cleaning agent used was 10% dichloromethane and 90% n-pentane; the inkjet cleaning agent was prepared according to the above ratio; the inkjet-printed area on the aluminum-plastic film surface was wiped.

[0028] Comparative Example 4: The cleaning agent consisted of 10% dichloromethane, 10% ethanol, and 80% n-pentane; the inkjet cleaning agent was prepared according to the above proportions; and the inkjet-printed area on the aluminum-plastic film surface was wiped.

[0029] Working process and principle: When using this device, the battery 101 to be wiped is placed in the placement groove 110 of the base plate 100 to ensure that the battery is in a stable position and easy to clean. The motor 106 is started, and the output end of the motor drives the rotating shaft 104 to start rotating. One end of the rotating shaft 104 is connected to the motor 106, and the other end is fixedly fitted with the first bevel gear 202. As the rotating shaft 104 rotates, the first bevel gear 202 will also start to rotate. The second bevel gear 203, which meshes with the first bevel gear 202, is located on the rotating rod 200. The rotating rod 200 rotates along with the first bevel gear 202. Since the rotating rod 200 is restricted to a certain range of movement by the limiting block 201 and the limiting groove, the stability and accuracy of the transmission are ensured. The roller shaft of the cleaning roller 109 passes through the mounting frame 108 and is fixedly provided with the fourth bevel gear 206. The third bevel gear 205, which meshes with the fourth bevel gear 206, is located on the fixed plate 204. As the rotating rod 200 rotates, the third bevel gear 205 will drive the fourth bevel gear 206 and the cleaning roller 109 to rotate together. Meanwhile, a cam 105 is fixedly sleeved on the rotating shaft 104. As the rotating shaft 104 rotates, the cam 105 will periodically contact and push the contact wheel 113, causing the mounting bracket 108 to reciprocate under the action of the fixed rod 111 and the spring 112. As the cleaning roller 109 rotates and reciprocates, the cleaning agent will be evenly applied to the battery surface and remove ink printing through physical and chemical action, thereby enhancing the cleaning effect of the cleaning roller 109 on the battery surface. The contact force between the cleaning roller 109 and the battery surface is moderate to avoid damaging the surface of the aluminum-plastic film of the battery cell.

[0030] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
