Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery core processing, and in particular to a lithium battery core pole surface milling device. Background Art

[0002] Traditional lithium battery cell pole surface milling equipment mostly uses manual operation, which has many disadvantages.

[0003] First, when the milling equipment is operated manually, the milling depth mainly depends on the operator's visual inspection and experience, which leads to inaccurate control of the milling depth, thus affecting the processing quality of the battery cell pole surface. In addition, manual operation can easily cause unstable milling speed, further affecting processing accuracy and efficiency.

[0004] Secondly, traditional milling equipment usually uses a simple base structure to fix the battery cell. There is a certain gap between the battery cell and the base, which makes the battery cell easy to move during the milling process. The movement of the battery cell not only affects the processing accuracy, but also may cause damage to the equipment and reduce the service life of the equipment.

[0005] Furthermore, the waste generated by traditional milling equipment during the processing process usually cannot be discharged automatically and needs to be collected manually. This not only increases the labor intensity of operators, but also reduces work efficiency. At the same time, the accumulation of waste may also affect the normal operation of the equipment and the working environment.

[0006] The industry has been seeking solutions to the above problems. In recent years, with the continuous development of automation technology, more and more companies have begun to try to apply automation technology to lithium battery cell pole surface milling equipment. By introducing technical means such as automated control systems, precise transmission mechanisms, and intelligent clamping devices, accurate, efficient, and stable processing of the cell pole surface can be achieved, while reducing the labor intensity of operators and improving production efficiency.

[0007] However, the automated milling equipment currently on the market still has certain limitations, such as complex structure, cumbersome operation, and high maintenance costs. Summary of the invention

The second bevel gear 1003 is rotatably connected to the forward and reverse adjustment seat 10, and the third bevel gear 1004 is rotatably connected to the feed control push frame 9. A spline groove is provided on the forward and reverse conversion shaft 1001 between the second bevel gear 1003 and the third bevel gear 1004, and the forward and reverse conversion portion where the spline groove is located is An adjusting collar 1005 is slidably engaged on the shaft 1001, and tooth grooves are respectively provided at both ends of the adjusting collar 1005. The ends of the second bevel gear 1003 and the third bevel gear 1004 are respectively provided with tooth grooves meshing with the adjusting collar 1005. An annular groove is provided in the middle of the adjusting collar 1005, and the shift fork 907 is in the annular groove of the adjusting collar 1005. The shift fork 907 moves the adjusting collar 1005 upward, and the adjusting collar 1005 meshes with the second bevel gear 1003. The feed motor 901 rotates, the forward and reverse conversion shaft 1001 rotates, the feed screw 902 rotates and pushes up, the shift fork 907 moves the adjusting collar 1005 downward, and the adjusting collar 1005 meshes with the third bevel gear 1004. The feed motor 901 rotates, the forward and reverse conversion shaft 1001 rotates, and the feed screw 902 rotates and withdraws.

[0062] The working principle of this embodiment:

[0063] First, the lithium battery cell 11 to be processed is placed between the fixed clamp seat 6 and the movable clamp seat 7, and the movable clamp seat 7 is operated to slide in the guide slot 402 until the battery cell 11 is stably clamped by the first clamping roller 601 and the second clamping roller 702. At this time, the lower end of the battery cell is in close contact with the roller wall of the driving roller 803, and the driving motor 806 is started to drive the driving roller 803 to rotate through the coupling, and the anti-skid protrusions on it provide stable rotation power for the battery cell;

[0064] Next, the milling head 5 is started to mill the pole surface of the battery cell. Since the milling table 4 and the base 1 are inclined at a 45-degree angle, the battery cell 11 can be naturally clamped in the lower bracket 805 to achieve positioning and alignment.

[0065] During the machining process, the feeding depth and direction of the milling head 5 need to be precisely controlled. At this time, the feeding motor 901 is started, and its rotating shaft drives the first bevel gear 905 to rotate. The first bevel gear 905 is meshed with the second bevel gear 1003 and the third bevel gear 1004. By controlling the shift fork 907 on the hand shaft 906 to shift the adjusting collar 1005 to slide on the forward and reverse conversion shaft 1001, the adjusting collar 1005 can be selectively meshed with the second bevel gear 1003 or the third bevel gear 1004.

[0066] When the adjusting collar 1005 is meshed with the second bevel gear 1003, the rotation of the first bevel gear 905 will drive the second bevel gear 1003 and the forward and reverse conversion shaft 1001 to rotate, and then drive the driven gear 904 to rotate through the driving gear 1002. Since part of the driven gear 904 slides and is engaged in the spline groove of the feed screw 902, the rotation of the driven gear 904 will drive the feed screw 902 to rotate and move on the feed control push frame 9, thereby pushing the push plate 903 and the entire drive chassis 8 and the milling head 5 to move upward, thereby realizing in-depth milling of the battery cell pole surface.

[0067] When it is necessary to adjust the feed direction of the milling head 5, it is only necessary to use the shift fork 907 to shift the adjustment collar 1005 to make it mesh with the third bevel gear 1004. At this time, the rotation of the first bevel gear 905 will drive the third bevel gear 1004 and the forward and reverse conversion shaft 1001 to rotate, but in the opposite direction to before, which will cause the feed screw 902 to rotate and move downward on the feed control push frame 9, thereby driving the driving chassis 8 and the milling head 5 to move downward, so as to achieve shallow milling or evacuation of the battery cell pole surface;

[0068] The waste generated during the processing will be discharged through the waste chip discharge plate 804. Since the bottom plate of the waste chip discharge plate 804 is made of magnetic material, it can effectively absorb the metal waste and prevent it from being scattered everywhere.

[0069] In addition, the buffer rod 801 and the buffer spring 802 at the bottom of the driving chassis 8 can reduce the vibration and impact of the equipment during the processing to a certain extent, and improve the stability and processing accuracy of the equipment.
