[0018] The specific implementation of the present application will be described in detail below in combination with the drawings and preferred embodiments.

[0019] As Figs. 1-3 shown, a polymer battery edge finishing mechanism, comprising installation base component, driving component, sliding component, elastic buffer component and finishing component. The installation base component provides installation support for the whole mechanism; the driving component drives the sliding component to do linear motion; the elastic buffer component is arranged between the sliding component and the finishing component, which plays a buffering protection role; the finishing component directly finishes the edge of the polymer battery.

[0020] The installation base component includes a bottom plate 1, a base rib plate 2 and a vertical plate 3. The bottom plate 1 is the basic installation component of the whole mechanism, and its material is usually selected from high-strength metal materials such as stainless steel or aluminum alloy to ensure sufficient strength and stability. The bottom plate 1 has a flat mounting surface, which is firmly connected with the equipment base plate by bolts and the like to ensure the stability of the overall installation of the mechanism.

[0021] The base rib plate 2 and the vertical plate 3 are connected to each other, the base rib plate 2 plays a role of strengthening the connection strength of the vertical plate 3 and the bottom plate 1, and is usually designed in a triangular or trapezoidal structure to enhance the stability of the structure. The vertical plate 3 is vertically installed on the bottom plate 1, the surface thereof is precisely processed, and a mounting hole is formed in the surface for mounting the driving component and the linear guide rail mounting seat 4. The installation of the vertical plate 3 needs to ensure the perpendicularity to ensure the accuracy of the subsequent component installation and operation.

[0022] The driving component is composed of a rodless cylinder 6 and a linear guide rail 5. The linear guide rail 5 is installed on the linear guide rail mounting seat 4, and the linear guide rail mounting seat 4 is fixedly connected with the vertical plate 3 through bolts. When installing, professional measuring tools need to be used to ensure the straightness and levelness of the linear guide rail 5, and ensure that the installation accuracy is within the specified range.

[0023] The rodless cylinder 6 is a driving power source, which is connected with the sliding component through a cylinder connecting plate 7. The cylinder connecting plate 7 is connected with the slider on the linear guide rail 5 at the same time, when the rodless cylinder 6 works, the cylinder connecting plate 7 is pushed, and then the sliding component connected with the cylinder connecting plate 7 is driven to move linearly along the slider of the linear guide rail 5. The installation of the rodless cylinder 6 needs to ensure the parallelism with the linear guide rail 5, so as to ensure the stability and accuracy of the movement of the sliding component.

[0024] The sliding component includes a sliding plate 8, a rib plate 9 and a bearing mounting vertical plate 10. The sliding plate 8 is fixedly connected with the cylinder connecting plate 7 of the driving component, and realizes linear motion under the action of the driving component. The sliding plate 8 is usually made of high-strength and light-weight metal material to reduce the motion inertia and improve the motion efficiency.

[0025] The rib plate 9 is installed between the sliding plate 8 and the bearing mounting vertical plate 10, and plays a role of strengthening the connection strength of the two. The shape and size of the rib plate 9 are designed according to the actual stress condition and structural requirement, and are usually fixed by welding or bolt connection.

[0026] The bearing mounting vertical plate 10 is used for installing the elastic buffer component, the surface thereof is provided with accurate mounting holes and clamping grooves to ensure the installation accuracy of the elastic buffer component. The bearing mounting vertical plate 10 is firmly connected with the sliding plate 8 and moves together with the sliding plate 8.

[0027] The elastic buffer component includes a shaft sleeve 12, a linear bearing 13, an elastic retaining ring for shaft 14, a spring guide block 15, a guide column 16 and a spring 17. Two elastic retaining rings for shaft 14 clamp the linear bearing 13 into the corresponding clamping grooves of the bearing mounting vertical plate 10, so as to ensure that the linear bearing 13 is firmly installed and positioned accurately.

[0028] The guide column 16 passes through the shaft sleeve 12, the linear bearing 13, the spring guide block 15 and the spring 17 in turn. The shaft sleeve 12 protects the guide column 16 and the linear bearing 13, reduces friction and wear. The spring guide block 15 guides the extension direction of the spring 17, ensures that the spring 17 does not bend or deviate during work. The end of the guide column 16 is connected with the finishing part. When the finishing part is subjected to resistance, the spring 17 will be compressed, playing a buffering role to prevent the battery from being pressed.

[0029] The finishing part includes a roller bracket 18, a roller shaft 19, a washer 20, a ball bearing 21 and a roller 22. Each roller 22 is installed with at least two ball bearings 21. After the roller shaft 19 passes through the washer 20, the ball bearing 21 and the washer 20, it is firmly installed on the roller bracket 18 by a nut or other fixing method. The washer 20 protects the ball bearing 21 and adjusts the installation gap.

[0030] The roller bracket 18 is connected with the guide column 16 of the elastic buffer part. When the sliding part drives the finishing part to move, the roller 22 rolls and finishes the polymer battery edge. The material of the roller 22 is usually selected from materials with high hardness, good wear resistance and high temperature resistance, such as SKD11, to ensure stable performance during long-term finishing work and ensure finishing effect.

[0031] When the device is running, first connect the power supply and gas source, and start the rodless cylinder 6. The rodless cylinder 6 pushes the cylinder connecting plate 7, driving the sliding part to move linearly along the linear guide rail 5. The movement of the sliding part is transmitted to the finishing part through the elastic buffer part.

[0032] Place the polymer battery after folding the edge in the finishing work area. When the roller 22 of the finishing part contacts the battery edge, it starts to roll and finish it. During the finishing process, if the roller 22 encounters a large resistance, the spring 17 of the elastic buffer part will be compressed, causing the roller 22 to shrink appropriately, avoiding excessive pressure on the battery and preventing the battery from being pressed and other appearance defects.

[0033] After completing a finishing operation, the rodless cylinder 6 moves reversely, driving the sliding part and the finishing part to return to the initial position, waiting for the next finishing task.

[0034] In the daily use of the mechanism, regular inspection and maintenance of each part are required, including checking the fastening of the bolts, the lubrication and wear of the linear guide rail 5, the elasticity of the spring 17, etc. Potential problems are found and handled in time to ensure stable operation and finishing effect of the mechanism.

[0035] For ordinary skilled people in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of the present application.
