Description

Technical Field

[0001] This utility model relates to a negative pressure formation process equipment for lithium batteries, belonging to the field of lithium battery production technology. Background Technology

[0002] Lithium batteries have many advantages such as high energy, small size, light weight, high specific energy, good safety, and flexible design, and are widely used in new energy vehicles and mobile digital products. Negative pressure components are auxiliary devices used in the formation equipment during the charging and discharging process of lithium batteries. During the charging and discharging process, excess gas and electrolyte bubbles are generated inside the battery, which are discharged through the battery filling port. If the gas is directly discharged into the workshop environment, it will directly harm the human body and cause pollution and corrosion to the equipment. In the existing technology, negative pressure components are generally used to discharge these excess gases and electrolytes.

[0003] For example, a lithium battery negative pressure formation device with patent number CN202221045584.0 includes: a material tray for carrying batteries; a support device including an upper support base, a lower support base, a guide column, an upper movable base, and a lower movable base, with the upper and lower ends of the guide column correspondingly fixed to the upper and lower support bases, and the upper and lower movable bases both disposed between the upper and lower support bases, the upper movable base being used for positioning the material tray; positive and negative electrode needle plate assemblies, the positive and negative electrode needle plate assemblies being disposed on the upper part of the lower movable base; a negative pressure device, the negative pressure device being disposed on the lower part of the upper support base; and a lifting device, the lifting device being used to drive the upper and lower movable bases to move upward along the guide column;

[0004] The aforementioned lithium battery negative pressure formation equipment controls the negative pressure formation process of lithium batteries, but the filling of the upper and lower parts of the lithium battery with the filler is only suitable for a limited range of lithium battery types, and the clamping and anti-loosening effect is limited. In addition, electrolyte residue may remain on the top of the lithium battery after the negative pressure is completed, which requires cleaning. This has certain adverse effects on actual use, so improvements are needed. Utility Model Content

This allows the electric telescopic rod two to control the movement of the elastic pull rod, pulling open the sealing door to discharge the electrolyte into the drain frame for subsequent cleaning. This achieves the effect of wiping and cleaning excess electrolyte on the lithium battery. Attached Figure Description

[0028] Specifically, such as Figures 1-6 As shown, the guide assembly includes a guide rail seat 16 and a guide sleeve 17. The guide rail seat 16 is fixedly connected to the lithium battery negative pressure formation device 1 near its front side. The guide sleeve 17 is fixedly connected to the bottom of the forward moving seat 5. The bottom of the guide sleeve 17 and the surface of the guide rail seat 16 are slidably connected.

[0030] Specifically, such as Figures 1-6As shown, an electric telescopic rod 25 is fixedly installed on the side of the cleaning frame 15 via a bracket. An elastic pull rod 26 is fixedly connected to the output end of the electric telescopic rod 25. A sealing door 27 is rotatably connected to the side of the cleaning frame 15 via a hinge.

Equipped with a water-absorbing brush plate 30, a U-shaped scraper plate 31 is fixedly installed on the top of the cleaning frame 15 near its inner wall. The operation of the waterproof electric cylinder 29 drives the water-absorbing brush plate 30 to move out of the cleaning frame 15 to absorb excess electrolyte that has fallen or overflowed above the lithium battery. The water-absorbing brush plate 30 squeezes and drains the electrolyte through the U-shaped scraper plate 31 in the cleaning frame 15 and stores it inside. The operation of the electric telescopic rod 25 controls the movement of the elastic pull rod 26 to pull open the sealing door 27 and discharge the electrolyte into the sewage box 28 for subsequent cleaning.

[0031] Please refer to Example 2 Figures 1-6 The difference between this embodiment and Embodiment 1 is that the main body of the constraint clamping frame 13 is an anti-slip stabilizing plate.

An extension clamping plate 22 is fixedly mounted on the output end of the electric push rod 21. Controlling the second main electric cylinder 19 drives the fitting clamping plate 20 to move smoothly. The operation of the electric push rod 21 can drive the extension clamping plate 22 to move, providing a large-scale constraint and stabilization effect for the lithium battery. A lower groove is provided on the top of the anti-slip stabilizing plate. An electric push rod 23 is fixedly mounted on the inner wall of the lower groove. A push-out plate 24 is fixedly connected to the output end of the electric push rod 23. The operation of the electric push rod 23 can drive the push-out plate 24 to move, pushing the lithium battery placed on top upwards for removal.

[0032] The working principle of this utility model is as follows: In use, a lithium battery negative pressure formation device 1 is set up to position and install the lithium battery. After negative pressure treatment, excess gas and electrolyte are discharged. The gas and electrolyte removed after treatment are extracted and discharged. During the lithium battery negative pressure formation process, the lithium battery is replaced and disassembled. Specifically, the electric cylinder 4 drives the lithium battery negative pressure formation device 1 in the front moving seat 5 to move back and forth. A guide rail 16 and a guide sleeve 17 are added to provide support below the front moving seat 5, facilitating the smooth movement of the front moving seat 5. Different types of lithium batteries are clamped and maintained in the constraint clamping frame 13. The main electric cylinder 19 drives the contact clamping plate 20 to move smoothly. The electric push rod 21 can move the extension clamping plate 22, providing a large-scale constraint and stabilization effect for the lithium battery. The electric telescopic rod 12 can change the height of the contact clamping plate 20, thereby achieving the constraint and positioning effect for lithium batteries of different specifications. If needed... When performing negative pressure formation on lithium batteries with multiple interfaces one by one, the drive motor 8 can be controlled to rotate the lead screw 9, and the moving nut seat 10 can be controlled to move smoothly. This allows for negative pressure treatment of the lithium battery's electrolyte filling interface. Because a locking groove 14 is provided at one end of the adjusting seat 7, the cleaning frame 15 can be disassembled and assembled. This allows the waterproof electric cylinder 29 to move the water-absorbing brush 30 out of the cleaning frame 15 to absorb excess electrolyte that has fallen or overflowed from the top of the lithium battery. The water-absorbing brush 30 squeezes and drains the U-shaped scraper 31 in the cleaning frame 15, storing the drained electrolyte inside. The collected electrolyte can then be discharged by operating the electric telescopic rod 25, which controls the elastic pull rod 26 to open the sealing door 27 and discharge the electrolyte into the drain box 28 for subsequent cleaning. This allows for convenient and automated negative pressure formation treatment of lithium batteries and the wiping and cleaning of excess electrolyte.
