Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a grinding device for a lithium battery shell. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium ion batteries. Due to its own high technical requirements, only companies in a few countries are producing this type of lithium metal battery. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the increasing use of lithium batteries, the manufacturing and processing of lithium batteries has become increasingly important, but there are still many defects in manufacturing and processing.

[0003] The existing technology has the following problems:

[0004] 1. The grinding device for lithium battery shell in the prior art is cumbersome to operate. The grinding device currently on the market requires multiple steps to completely grind the lithium battery shell when grinding the lithium battery shell. In most cases, manpower is required to perform secondary or even multiple grindings, which increases labor costs, wastes time, has low practicality, and will hinder the manufacturing and processing of lithium batteries, causing economic losses.

[0005] 2. The grinding device for lithium battery shell in the prior art has poor grinding effect. The grinding devices currently on the market often cause incomplete grinding and excessive damage when grinding lithium battery shells, and the grinding surface is often rough. The grinding effect is very poor, and manual secondary grinding is often required, which is time-consuming, labor-intensive, wastes resources, and increases the manufacturing and processing costs of lithium batteries.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] The preferred embodiment of the lithium battery shell grinding device provided by the utility model is as follows Figures 1 to 5 As shown: A grinding device for lithium battery shell, including a body 1 and a grinding mechanism 8, the top of the body 1 is fixedly connected to an air box 2, the side of the air box 2 is fixedly connected to an air outlet pipe 18, the other end of the air outlet pipe 18 is respectively fixedly connected to a push-pull cylinder solenoid valve 15, a lifting cylinder solenoid valve 16 and a clamp solenoid valve 17, one side of the push-pull cylinder solenoid valve 15 is fixedly connected to a push-pull cylinder air supply pipe 19, the other end of the push-pull cylinder air supply pipe 19 is fixedly connected to a push-pull cylinder 4, the output shaft of the push-pull cylinder 4 is fixedly connected to a push-pull telescopic rod 5, and the push-pull telescopic rod 5 is fixedly connected to a slider 10 at the other end, a lifting cylinder solenoid valve 16 is fixedly connected to a lifting cylinder air supply pipe 20 at one side, the other end of the lifting cylinder air supply pipe 20 is fixedly connected to the slider 10, the bottom of the slider 10 is fixedly connected to a lifting cylinder 9, the output shaft of the lifting cylinder 9 is fixedly connected to a lifting telescopic rod 7, the other end of the lifting telescopic rod 7 is fixedly connected to a clamp arm 22, one side of the clamp arm 22 is fixedly connected to a telescopic clamp rod 23, the other end of the telescopic clamp rod 23 is fixedly connected to a clamp block 24, and the inner bottom wall of the body 1 is fixedly connected to a motor 3.

[0025] In this embodiment, the inner top arm of the machine body is fixedly connected with the slide rail 6, and a slide groove 14 is opened on the top of the slide rail 6. The slide groove 14 is slidably connected with the slider 10, and there is no gap on the contact surface. This arrangement can ensure that when the push-pull cylinder 4 pushes and pulls the slider 10, the slider 10 will move smoothly and stably, thereby driving the lifting cylinder 9 to move smoothly, saving manpower.

[0026] In this embodiment, a fixed limit block 13 is fixedly connected to the top of the slide groove 14, a spring 12 is fixedly connected to one side of the fixed limit block 13, and a sliding limit block 11 is fixedly connected to the other end of the spring 12. This arrangement can provide buffering and shock absorption for the slider 10, reduce damage caused by collision between the slider 10 and the slide groove 14, and extend the service life of the device. Example

[0027] On the basis of Example 1, a preferred embodiment of the lithium battery housing polishing device provided by the present invention is as follows: Figures 1 to 5As shown: the grinding mechanism 8 mainly includes a rotating shaft 806 and a grinding block 807, one end of the rotating shaft 806 is fixedly connected to a transmission belt limit block 804 and a bearing inner shaft 801, the outer wall of the rotating shaft 806 is fixedly connected to a transmission belt 805, the outer wall of the bearing inner shaft 801 is movably connected to a rolling body 802, the outer wall of the rolling body 802 is movably connected to the bearing outer shaft 803, and the outer wall of the bearing outer shaft 803 is fixedly connected to a fixed block 808, so that the lithium battery shell can be fully ground and the grinding effect is improved.

[0028] Furthermore, the rolling body 802 blocks the transmission of the torque of the bearing inner shaft 801 to the bearing outer shaft 803 by its own rotation. This arrangement ensures that the bearing outer shaft 803 is fixed due to the presence of the rolling body 802 when the bearing inner shaft 801 rotates, thereby increasing the rationality of the device.

[0029] At the same time, there are multiple rotating shafts 806 and grinding blocks 807, which are exactly the same in shape and size and are installed on the inner bottom wall of the body 1 at equal intervals. This arrangement can ensure the grinding effect of the lithium battery shell and increase the working efficiency of the device.

[0030] In addition, preferably, the push-pull cylinder air supply pipe 19, the lifting cylinder air supply pipe 20 and the clamp air supply pipe 21 are all high-elasticity hoses. The use of high-elasticity hoses can extend their service life and ensure the rationality of the device.

[0031] When in use, the gas box 2 provides gas to the push-pull cylinder solenoid valve 15, the lifting cylinder solenoid valve 16 and the clamp solenoid valve 17 through the air outlet pipe 18. After the push-pull cylinder solenoid valve 15 is opened, the push-pull cylinder 4 is controlled to work through the push-pull cylinder air supply pipe 19.

After reaching the appropriate position, the lifting cylinder solenoid valve 16 is opened, and the lifting cylinder 9 is controlled to work through the lifting cylinder air supply pipe 20. The clamp arm 22 is pushed by the lifting telescopic rod 7. After reaching the specified position, the clamp solenoid valve 17 is opened, and the telescopic clamp rod 23 is controlled through the clamp air supply pipe 21. The lithium battery is clamped by the clamp block 24 fixedly connected at one end. The operation is simple;

[0032] When the lithium battery shell needs to be polished, the output shaft of the motor 3 rotates the inner shaft 801 of the bearing fixedly connected through the coupling, thereby driving the rotating shaft 806 fixedly connected at one end to rotate, and finally driving the polishing block 807 fixedly connected to the outer wall of the rotating shaft 806 to perform high-speed transmission, so that the lithium battery shell can be easily polished. Due to the presence of multiple groups of polishing blocks 807, the push-pull cylinder 4 pushes the slider 10 to slide on the slide groove 14, which can realize the complete polishing of the lithium battery shell at multiple angles, thereby improving the polishing effect of the device.

[0033] In summary, the grinding device for the lithium battery shell can easily realize the clamping and movement of the lithium battery, and through the cooperation with multiple groups of grinding blocks, the grinding effect of the device on the lithium battery shell and the convenience of the device are improved to a certain extent.
