Description

Technical Field

[0001] The invention relates to the field of low-temperature tab glue, and in particular to low-temperature tab glue and manufacturing equipment. Background Art

[0002] With the rapid development of new energy and electric vehicle industries, battery technology has received increasing attention; as a core component of the battery, the tab has an important impact on the overall performance of the battery; in order to meet the use requirements in low-temperature environments, it is crucial to develop low-temperature tab glue with stable performance; existing low-temperature tab glue usually adopts a multi-layer structure design, including a specific ratio of glue layer, filler, insulation layer and follower layer to ensure the stability and safety of the battery under cold conditions; however, the high-performance materials and complex design of the existing tab glue have pushed up the manufacturing cost; secondly, the multi-layer structure and special material ratio increase the processing difficulty and require high-precision equipment and processes; finally, the existing low-temperature tab glue is prone to stratification due to the difference in the material ratio between the middle layer and the surface film layer.

[0003] For example, the Chinese invention patent (application number: CN202310145570.9) discloses a "ear glue structure and its preparation method". Its specification discloses that the ear of a soft-pack lithium battery is generally composed of a metal strip and an ear glue tape symmetrically attached to the two surfaces of the metal strip. The ear glue tape mainly plays an insulating role to prevent the metal strip from directly contacting the aluminum-plastic film and forming a short circuit. The existing ear glue tape generally has three layers. The middle film layer of the three-layer ear glue is generally made of a material with a high melting point, and the surface film layer is co-extruded with a low melting point material. However, the materials of the middle film layer and the surface film layer are different, and the bonding force between the middle film layer and the surface film layer is low. Therefore, under the long-term immersion corrosion of the battery electrolyte, the ear glue is prone to stratification, resulting in cracking of the battery seal, and eventually the problem of electrolyte leakage, and a low service life; the above patents can prove the defects of the existing technology.

[0004] Therefore, we made improvements to this and proposed low-temperature ear glue and manufacturing equipment. Summary of the invention

At the same time, the pressurizing component is used to facilitate adjustment of the meshing object of the gear 305, thereby achieving adjustment of the rotating object.

[0039] The use process of the low-temperature tab glue and manufacturing equipment provided by the present invention is as follows: When in use, the device is first placed at an appropriate location, and the raw materials to be mixed are fed into the mixing tank 101 through the feed pipe 102 connected to the top of the mixing tank 101; At this time, water of the required temperature is transported to the inside of the rotating tube 201 through the water transporting member 306, and the water is transported to the inside of the fixed sleeve 205 connected to the outer array thereof, and the telescopic rod 206 is pushed outward under the continuous transport of the water flow, thereby pushing the connecting rod 207 and the spring piece 203 to move, so that the contact surface between the spring piece 203 and the inner wall of the mixing tank 101 is continuously increased until it moves to an appropriate position, at which time the water transport is stopped, and the servo motor 301 is started to rotate forward, and the servo motor 301 drives the gear 305 and the rotating gear meshing with the gear 305 through the first square tube 302 and the second square tube 303 set at its output end. The tube 201 rotates, thereby driving the spring pieces 203 of the array to rotate. Since the spring pieces 203 are in contact with the inside of the mixing tank 101, a large amount of heat will be generated when rotating at a high speed, and the raw materials will be continuously stirred and mixed. At this time, the raw materials can be directly heated. In this rotation direction, the spring pieces 203 first contact the side where the compression molding plate 104 and the mixing tank 101 meet, and then squeeze the compression molding plate 104 to rotate during the rotation process. When leaving the compression molding plate 104, the spring pieces 203 and the block 204 fixedly installed on the outer wall of the spring pieces 203 are in contact with the mixing tank 101 again, and vibration is generated, thereby preventing the raw materials from adhering to the surface of the spring pieces 203 and the mixing tank 101. When the heating temperature inside the mixing tank 101 needs to be adjusted, the rotation speed of the servo motor 301 can be reduced first, and the heat can be dissipated through the heat-conducting spring piece 203 and the water source, so as to quickly cool down. At the same time, the water source can be discharged through the water transporting part 306, so that the contact area between the spring piece 203 and the inner wall of the mixing tank 101 is reduced, thereby reducing the speed of temperature rise, thereby achieving natural heat dissipation and temperature reduction until the raw materials are mixed; At this time, the servo motor 301 can be started in reverse, and the spring piece 203 is kept in contact with the inner wall of the mixing tank 101. The servo motor 301 drives the spring piece 203 to rotate in the opposite direction. At this time, the spring piece 203 first contacts the other side of the compression molding plate 104. At this time, the block 204 fixedly installed on the outside of the spring piece 203 will be engaged with the slot 105 provided on the outside of the compression molding plate 104, and then the compression molding plate 104 is lifted up during rotation, so that it rotates around the hinge. Since the compression molding plate 104 is connected by a rebound hinge, and the block 204 is an elastic sheet, when the compression molding plate 104 is tilted forty-five degrees, the rebound force of the hinge is greater than the bending elastic force of the block 204, so that the block 204 bends and separates from the slot 105. At this time, the compression molding plate 104 rebounds and compression molds the mixed material flowing into its bottom, and so on and so forth until the compression molding is completed. At this time, the pressure-applying member 307 can be used to apply pressure to the interior of the rotating tube 201, and its internal pressure is made greater than the elastic force of the limit spring 304. At this time, the extrusion plate 211 moves toward the gear 305 under the push of pressure until it contacts the second square tube 303, and pushes the gear 305 to move, so that the gear 305 is meshed with the sealing sleeve 209. At this time, the servo motor 301 is started, and the servo motor 301 drives the mixing tank 101 to rotate through the gear 305 and the sealing sleeve 209, and changes the angle of the feed pipe 102 until it is adjusted to an appropriate angle. At this time, the pressure is released through the pressure-applying member 307, so that the gear 305 is reset. At this time, the above steps are repeated, and the discharge port 106 and the feed pipe 102 are opened, and the servo motor 301 is started to drive the spring piece 203 to rotate, so as to form a negative pressure, thereby dissipating heat through the feed pipe 102 and cooling the compression member.
