Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, specifically to a liquid injection mechanism for lithium battery production that is designed to prevent tipping. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal and lithium alloys as negative electrode materials and non-aqueous electrolyte solutions. They have advantages such as high energy density, long lifespan, and low self-discharge rate, and are widely used in consumer electronics, new energy vehicles, energy storage and other fields.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, the inability to inject liquid in batches means that only one lithium battery can be operated. Compared with batch injection, the frequency of equipment operation and working time will increase significantly. At the same time, the equipment will vibrate during operation. If the position of the lithium battery cannot be positioned, it will cause it to tip over during the injection process, which seriously threatens the life safety of personnel and the safety of equipment and property in the production workshop.

[0004] To address the aforementioned problems, the inventors have proposed a tipping-proof liquid injection mechanism for lithium battery production. Utility Model Content

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a liquid injection mechanism for lithium battery production that can prevent tipping, comprising a table, a plurality of clamping components distributed at equal intervals are fixedly connected to the top surface of the table, a sliding component is provided on the top surface of the table, the sliding component includes a protective shell, one side of the protective shell is fixedly connected to the table, the two sides of the protective shell are rotatably connected to a first rotating shaft, a motor is fixedly connected to one side of the protective shell, the output end of the motor extends into the protective shell and is fixedly connected to the first rotating shaft, two first bevel gears are sleeved on the outer surface of the first rotating shaft, a second bevel gear is meshed on the outer surface of the first bevel gear, a lead screw is fixedly connected to one side of one of the second bevel gears, a guide rod is fixedly connected to one side of the other second bevel gear, a through groove is symmetrically opened on the top surface of the table, a bracket is slidably connected to the outer surface of the through groove, the outer surface of the lead screw is threadedly sleeved with the lower part of the bracket, the outer surface of the guide rod is movably sleeved with the lower part of the bracket, and a plurality of liquid injection tubes distributed at equal intervals are fixedly passed through the top surface of the bracket.

A through groove 208 is symmetrically opened on the top surface of the platform 1. The ends of the lead screw 206 and the guide rod 207 are rotatably connected to the inner wall of one side of the through groove 208, respectively.

[0031] Under the threaded drive of the lead screw 206 and the guidance of the guide rod 207, the bracket 209 slides along the through groove 208. Multiple liquid injection tubes 210 fixedly penetrate the top surface of the bracket 209 move synchronously with the bracket 209, which can effectively inject liquid into lithium batteries in batches.

[0032] The clamping assembly 3 includes multiple support plates 301 arranged in a rectangular array. The bottom ends of the multiple support plates 301 are fixedly connected to the table surface 1.

A toothed plate 304 is slidably connected to the inner wall of the first sliding groove 303. The outer surface of the toothed plate 304 is in contact with the inner wall of the first sliding groove 303. A drive gear 305 is meshed with one end of the opposite side of the toothed plate 304.

[0034] The working principle of the anti-tipping liquid injection mechanism for lithium battery production according to an embodiment of this application is as follows: Multiple support plates 301 are fixed at their bottom ends on a table 1.

A toothed plate 304 can slide along the inner wall of a first sliding groove 303 at the lower part of one end of the opposite side of the fixed plate 302. Rotating the rotating plate 306 drives the drive gear 305 to rotate. The drive gear 305 meshes with the toothed plate 304, causing the two toothed plates 304 to move towards each other along the first sliding groove 303. Multiple clamping frames 307 fixed to the top of the toothed plate 304 move synchronously with the toothed plate 304. The fixing blocks 308 at the lower ends of the card frame 307 cooperate with the second sliding groove 309 at the upper end of the opposite side of the fixing plate 302 to ensure the stability of the movement of the card frame 307. The battery case 313 is placed between the card frames 307. By rotating the rotating plate 306, the card frames 307 move towards each other. The battery case 313 is inserted into the card groove 310 at the opposite side of the card frame 307. The magnet 311 on one side of the card frame 307 cooperates with the magnetic groove 312 on the other side of the card frame 307 to attract each other, further enhancing the fixing effect on the battery case 313, thereby effectively preventing the lithium battery from tipping over during the liquid filling process.

[0035] The motor 203 is started, and its output end drives the first rotating shaft 202 to rotate. The two first bevel gears 204 sleeved on the outer surface of the first rotating shaft 202 rotate accordingly. The first bevel gears 204 mesh with the second bevel gear 205, driving the second bevel gear 205 to rotate. The lead screw 206 and guide rod 207 fixedly connected to the second bevel gear 205 rotate. The ends of the lead screw 206 and guide rod 207 are respectively rotatably connected to the inner wall of one side of the through groove 208. The lower part of the bracket 209 is threadedly sleeved with the lead screw 206 and movably sleeved with the guide rod 207. When the lead screw 206 rotates, the bracket 209 slides along the direction of the through groove 208 under the threaded transmission of the lead screw 206 and the guiding action of the guide rod 207. Multiple liquid injection tubes 210 fixedly penetrate the top surface of the bracket 209 move synchronously with the bracket 209, thereby achieving the purpose of effectively injecting liquid into lithium batteries in batches.
