Description

Technical Field

[0001] This utility model relates to the field of secondary positioning technology for battery cells, specifically to a high-precision positioning battery cell electrode transfer device. Background Technology

[0002] With the rapid development of the new energy industry, the demand for lithium-ion batteries, solid-state batteries, and other battery cells is increasing in fields such as electric vehicles and energy storage systems. During the cell assembly process, the cell packs are transferred from the material box to the tray. Due to slight differences in the distance between the material box and the tray, grippers move the cells from the material box to the tray to ensure the alignment, spacing, and overall structural stability of the cells, thereby improving the safety and performance of the battery system.

[0003] Currently, secondary positioning mainly uses mechanical positioning, which requires multiple drives to adjust and position the battery cell in the horizontal and vertical directions. This method requires multiple handling actions, which is cumbersome and inefficient. In addition, although some solutions that use vision or sensor-assisted positioning can improve accuracy, they are complex in structure and expensive, making them unsuitable for large-scale production scenarios.

[0004] Based on this, this utility model designs a high-precision positioning type battery cell electrode transfer device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-precision positioning battery electrode transfer device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-precision positioning battery cell electrode transfer device includes a support plate and a battery cell transfer mechanism. The battery cell transfer mechanism is connected to the support plate. The battery cell transfer mechanism includes a cylinder fixing plate, a drive assembly, a guide assembly, a limit assembly, a detection assembly, a secondary positioning assembly, and a support assembly. The cylinder fixing plate is fixedly connected to the upper end of the support plate. The drive assembly is connected to the support plate and the secondary positioning assembly. The guide assembly is connected to the cylinder fixing plate and the limit assembly. Two sets of guide assemblies and limit assemblies are symmetrically distributed front and back on the support plate. The guide assembly is connected to the support plate and the secondary positioning assembly. Two sets of symmetrically distributed detection assemblies are connected to the secondary positioning assembly and the drive assembly. The secondary positioning assembly and the support assembly are both connected to the support plate. The secondary positioning assembly is used to accurately position the battery cell.

[0008] Furthermore, the secondary positioning component includes support corner blocks, positioning push plates, and positioning blocks. Two sets of positioning push plates located above the support plate are symmetrically distributed on the left and right. Multiple sets of positioning blocks distributed at equal intervals are fixedly connected to the inner wall of the positioning push plates.

[0009] Furthermore, the positioning block has a structure that is narrow on the inside and wide on the outside, with a chamfered transition in the middle;

[0010] Furthermore, the drive assembly includes a thin cylinder and a floating joint. The housing of the thin cylinder is fixedly connected to the cylinder mounting plate, the output end of the thin cylinder is fixedly connected to the floating joint, and the floating joint is fixedly connected to the positioning push plate located on the left side.

[0011] Furthermore, the speed control valve is fixedly connected to the air inlet of the thin cylinder. The speed control valve is used to adjust the airflow of the thin cylinder, thereby controlling the movement speed and playing a buffering role.

[0012] Furthermore, the guide assembly includes a linear bearing and a guide shaft.

[0013] Furthermore, the limiting component includes a buffer pad and a limiting ring. The limiting ring is fixedly connected to the left end of the guide shaft, and the buffer pad is fixedly connected to the right end of the limiting ring. The buffer pad and the limiting ring are used to limit the maximum displacement distance of the positioning push plate to avoid damage to the product's battery cell.

[0014] Furthermore, the detection component includes a through-beam photoelectric sensor and a through-beam photoelectric mounting sheet metal. The through-beam photoelectric mounting sheet metal is fixedly connected to the positioning push plate located on the right side.

[0024] Example 1: In some embodiments, please refer to the accompanying drawings. Figure 1 and Figure 2 A high-precision positioning type battery cell electrode transfer device includes a support plate 1 and a battery cell transfer mechanism, wherein the battery cell transfer mechanism is connected to the support plate 1;

[0025] The cell transfer mechanism includes a cylinder fixing plate 14, a drive assembly, a guide assembly, a limit assembly, a detection assembly, a secondary positioning assembly, and a support assembly. The cylinder fixing plate 14 is fixedly connected to the upper end of the support plate 1. The drive assembly is connected to the support plate 1 and the secondary positioning assembly. The guide assembly is connected to the cylinder fixing plate 14 and the limit assembly. Two sets of guide assemblies and limit assemblies are symmetrically distributed on the support plate 1. The guide assembly is connected to the support plate 1 and the secondary positioning assembly. Two sets of symmetrically distributed detection assemblies are connected to the secondary positioning assembly and the drive assembly. The secondary positioning assembly and the support assembly are both connected to the support plate 1. The secondary positioning assembly is used to accurately position the cell.

[0026] The secondary positioning component includes a support corner block 2, a positioning push plate 3, and a positioning block 4. Two sets of positioning push plates 3 located above the support plate 1 are symmetrically distributed on the left and right. Multiple sets of positioning blocks 4, which are distributed at equal intervals, are fixedly connected to the inner wall of the positioning push plate 3. Two sets of support corner blocks 2 are fixedly connected to the outer wall of the positioning push plate 3 located on the right. The lower end of the support corner block 2 is fixedly connected to the support plate 1. The positioning push plate 3 located on the right is connected to the detection component. The positioning push plate 3 located on the left is connected to the drive component and the guide component, respectively.

[0027] Positioning block 4 has a structure that is narrow on the inside and wide on the outside, with a chamfer in the middle to make positioning smoother.

[0028] Positioning block 4 is made of PEEK plastic, taking advantage of its wear resistance, corrosion resistance, insulation and smooth surface.

[0029] The drive assembly includes a thin cylinder 7 and a floating joint 9. The housing of the thin cylinder 7 is fixedly connected to the cylinder fixing plate 14. The output end of the thin cylinder 7 is fixedly connected to the floating joint 9. The floating joint 9 is fixedly connected to the positioning push plate 3 located on the left side.

[0030] The speed control valve 8 is fixedly connected to the air inlet of the thin cylinder 7. The speed control valve 8 is used to adjust the airflow of the thin cylinder 7, thereby controlling the movement speed and playing a buffering role.

[0031] The guide assembly includes a linear bearing 10 and a guide shaft 12. The right wall of the linear bearing 10 is fixedly connected to the cylinder fixing plate 14. The right end of the guide shaft 12 is fixedly connected to the positioning push plate 3 located on the left side. The guide shaft 12 is slidably connected to the linear bearing 10. The cylinder fixing plate 14 has a through hole for limiting and sliding connection with the guide shaft 12. The left end of the guide shaft 12 is connected to the limiting assembly.

[0032] The limiting assembly includes a buffer pad 11 and a limiting ring 13. The limiting ring 13 is fixedly connected to the left end of the guide shaft 12, and the buffer pad 11 is fixedly connected to the right end of the limiting ring 13. The buffer pad 11 and the limiting ring 13 are used to limit the maximum displacement distance of the positioning push plate 3 to avoid damage to the product cell 6.

[0033] The cushioning pad 11 is made of polyurethane and serves as a cushioning element.

[0034] The detection assembly includes a through-beam photoelectric sensor 5 and a through-beam photoelectric mounting sheet metal 17. The through-beam photoelectric mounting sheet metal 17 is fixedly connected to the positioning push plate 3 located on the right side. The through-beam photoelectric sensor 5 is fixedly connected to the through-beam photoelectric mounting sheet metal 17 and is electrically connected to the thin cylinder 7.

[0035] The support assembly includes a connecting base plate 15 and support rods 16. Four sets of support rods 16 are located at the four corners of the support plate 1. One end of each support rod 16 is fixedly connected to the support plate 1, and the other end of each support rod 16 is fixedly connected to the connecting base plate 15.

[0036] In this invention, after the product cell 6 is transported from the material box to the secondary positioning platform using grippers, the grippers are removed. The cell transfer device is fixed to the secondary positioning platform via the connecting base plate 15 and the supporting rod 16. Due to the narrow inner side of the positioning block 4, the product cell 6 can be easily inserted. When the photoelectric sensor 5 on the photoelectric mounting sheet metal 17 detects the insertion of the product cell 6, the thin cylinder 7 is activated. Under the speed adjustment and buffering of the speed regulating valve 8, it pushes the floating joint 9 to move to the right. During the movement, the cylinder fixing plate 14, the linear bearing 10, and the guide shaft 12 play a guiding role. This allows the positioning push plate 3 on the left to move horizontally to the right. At the same time, the buffer pad 11 and the limiting ring 13 limit the maximum distance of movement to the right to prevent damage to the product cell 6. Thus, the positioning push plate 3 and positioning block 4 on the left move to the right, while the positioning push plate 3 and positioning block 4 on the right are fixed to the support plate 1 by the support corner block 2. As a result, the two sets of positioning push plates 3 move closer to each other. Since the positioning block 4 is narrower inside and wider outside, the width between the two sets of positioning blocks 4 also decreases. Thus, the product cell 6 is accurately and smoothly positioned. After the secondary positioning is completed, the product cell 6 is positioned and ready for transportation.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
