[0029] See also Figure 1-4 The utility model provides a technical solution: a lithium battery pole ear welding auxiliary tooling, including a base 1, a servo motor 2, a central axis 3, a base plate 4, a lithium battery positioning groove 5, a pusher electric telescopic rod 6, a pusher plate 7, a clamping electric telescopic rod 8, a clamping plate 9, a support plate 10, a horizontal plate 11, a track window 12, a locking bolt 13, a locking nut 14, a storage box 15, a feeding electric telescopic rod 16 and a feeding plate 17. A servo motor 2 is fixed in the base 1, and a central axis 3 is installed on the top of the servo motor 2. The central axis 3 is rotatably connected to the top of the base 1 through a bearing seat, and the top of the central axis 3 is connected and fixed to the center of the bottom surface of the base plate 4. A lithium battery positioning groove 5 is opened on the edge of the top surface of the base plate 4;

[0030] A material pushing electric telescopic rod 6 is fixed to the end of the inner wall of the lithium battery positioning groove 5, and a material pushing plate 7 is installed at the end of the material pushing electric telescopic rod 6. A clamping electric telescopic rod 8 is fixed on the inner wall of the lithium battery positioning groove 5, and a clamping plate 9 is fixed to the end of the clamping electric telescopic rod 8.

[0031] A support plate 10 is fixed to one side of the outer wall of the base 1, and a horizontal plate 11 is installed on the top of the support plate 10. A track window 12 is penetrated through the middle of the horizontal plate 11, and a locking bolt 13 is penetrated through the track window 12. A locking nut 14 is installed at the bottom end of the locking bolt 13. The top of the locking bolt 13 is connected and fixed to the bottom surface of the storage box 15, and a feeding electric telescopic rod 16 is penetrated and fixed at the end of the storage box 15, and a feeding plate 17 is installed at the end of the feeding electric telescopic rod 16.

[0032] The lithium battery positioning grooves 5 in this example are distributed at equal angles about the center of the base plate 4, and the inner bottom surface of the lithium battery positioning grooves 5 and the inner bottom surface of the storage box 15 are on the same horizontal plane. The above-mentioned structural design enables multiple lithium batteries to be stored on the base plate 4, and ensures that the lithium batteries in the lithium battery positioning grooves 5 can be stably aligned with the pole ears in the storage box 15.

[0033] The length of the electric telescopic rod 6 for pushing materials in this example is greater than half the length of the lithium battery positioning groove 5, and the width of the pushing plate 7 at the end of the electric telescopic rod 6 is less than 1 / 3 of the width of the lithium battery positioning groove 5. The above structural design ensures that the electric telescopic rod 6 for pushing materials can push the pushing plate 7 to drive the lithium battery to move linearly a sufficient distance, which not only ensures the fit between the lithium battery and the pole ear, but also facilitates the ejection of the lithium battery after the pole ear is installed.

[0034] The clamping electric telescopic rod 8 in this example is symmetrically distributed about the clamping plate 9, and the clamping plate 9 is symmetrically distributed about the center of the lithium battery positioning groove 5. The above structural design enables the clamping plate 9 to stably clamp and fix the lithium battery in the center, which is convenient for welding the pole ear.

[0035] The locking bolt 13 in this example is slidably connected to the track window 12, and the length of the track window 12 is not less than the width of the lithium battery positioning groove 5. The above-mentioned structural design enables the storage box 15 to slide stably along the track window 12 with the locking bolt 13 to adjust the spacing to adapt to the installation requirements of positive and negative electrode ears with different spacings.

[0036] The length of the feeding electric telescopic rod 16 in this example is greater than half the length of the storage box 15, and the storage box 15 is symmetrically distributed about the center of the track window 12.

[0037] Working principle: During installation, the conveying mechanism of lithium-ion batteries without tabs installed and the conveying mechanism of lithium-ion batteries with tabs installed are placed at Figure 3 Different orientations of the circular base 4;

[0038] According to the requirements of the installation spacing of the positive and negative electrode tabs, push the storage box 15 with the locking bolt 13 to slide linearly along the track window 12 until the spacing of the storage box 15 is appropriate, screw up the locking nut 14 to squeeze the bottom surface of the horizontal plate 11, fix the position of the storage box 15, and place the positive and negative electrode tabs in different storage boxes 15;

[0039] Then, the servo motor 2 drives the central axis 3 to rotate stably with the base plate 4 and the lithium battery positioning groove 5, and the conveying mechanism of the lithium battery without the tab installed conveys the lithium battery without the tab installed into the lithium battery positioning groove 5. When the lithium battery positioning groove 5 with the lithium battery rotates and aligns with the storage box 15, the servo motor 2 stops working, controls the material pushing electric telescopic rod 6 to extend and push the material pushing plate 7, and the material pushing plate 7 pushes the lithium battery to move a suitable distance in the direction of the storage box 15, controls the symmetrically distributed clamping electric telescopic rods 8 to extend synchronously, and pushes the symmetrically distributed clamping plates 9 to clamp and fix the lithium battery in the center;

[0040] Then the feeding electric telescopic rod 16 at the end of the two storage boxes 15 is extended to push the feeding plate 17, and the feeding plate 17 pushes the positive and negative pole ears to fit the installation position of the lithium battery in a straight line, and the welding tool is used to weld the pole ears and the lithium battery. After the welding is completed, the clamping electric telescopic rod 8 is shortened and reset to release the lock of the lithium battery, and the feeding electric telescopic rod 16 is shortened and reset, and the new positive and negative pole ears are placed in the storage box 15. The servo motor 2 controls the central axis 3 to rotate with the base plate 4 again, and the lithium battery with the pole ears installed rotates away from the storage box 15 and moves to be aligned with the conveying mechanism of the lithium battery with the pole ears installed. The pushing electric telescopic rod 6 is extended to the longest, and the lithium battery with the pole ears installed is pushed out of the lithium battery positioning slot 5, and is conveyed to the next processing mechanism by the conveying mechanism. The base plate 4 continues to rotate to align the lithium battery without the pole ears installed with the storage box 15, and the above steps are repeated to perform continuous lithium battery pole ear installation.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
