Traditionally, manual lathe operation is associated with slow clamping speeds, low production efficiency, and inconsistent product quality. Manual operation also presents significant safety risks. Using molds for cutting reduces the surface quality of the cut surface, impacting the yield rate of subsequent welding processes. Automatic lathes are also an existing processing technology, improving production efficiency and product quality. However, these machines can only process a single product at a time, and the speed of product transportation and clamping still needs to be improved. Summary of the Invention

[0035] See also Figures 1 to 5 As shown, this preferred embodiment provides a battery shell peeling machine, which includes a workbench 1, a rotating mechanism 2 and a lifting mechanism 3.

[0036] Among them, the workbench 1 is provided with a loading station 11, a processing station 12 and an unloading station 13 evenly distributed in a ring shape. The loading station 11 and the unloading station 13 are both provided with a support platform 14 for placing the workpiece 8, and the processing station 12 is provided with a rotary cutting tool 15.

[0037] The loading station 11 is connected to the loading line 4, and the unloading station 13 is connected to the unloading line 5. The loading line 4 is provided with N conveyor lines 41 (N = 1, 2, 3 ...). In this embodiment, four conveyor lines 41 are used as an example. The unloading line 5 is also provided with four loading stations 11, four processing stations 12, and four unloading stations 13, respectively, so that four workpieces 8 can be processed simultaneously. Furthermore, the processing stations 12 are further divided into roughing stations 12a and finishing stations 12b to improve the quality of the cross-section. There are a total of sixteen stations, and the workpieces 8 at the same station move synchronously.

[0038] The rotary mechanism 2 includes a turntable 21 that is rotatably mounted above the worktable 1. The turntable 21 rotates through a set angle (here, 90°) so that the workpiece 8 passes through the loading station 11, the roughing station 12a, the finishing station 12b, and the unloading station 13. Multiple rotary chucks 22 are mounted on the turntable 21, corresponding to each of the loading stations 11, the processing stations 12, and the unloading stations 13. Several rotary motors 23 are distributed around the turntable 21, each mounted on the output shaft of each motor. The rotary chucks 22 are used to clamp the workpiece 8 and rotate it, satisfying the requirements of the peeling operation.

[0039] The workbench 1 is provided with a bracket 16, on which a rotary motor 24 is provided. A support shaft is erected between the bracket 16 and the workbench 1, and the rotary disk 21 is driven to rotate around the support shaft by the rotary motor 24. In addition, a work light 18 arranged around the rotary disk 21 is hung on the bracket 16.

[0040] The lifting mechanism 3 is located below the workbench 1 and includes a lifting cylinder 31 arranged one by one corresponding to the loading station 11, the processing station 12 and the unloading station 13. Here, it is preferably an electric cylinder. The lifting cylinder 31 is used to lift the corresponding support platform 14 and the rotary cutting tool 15 so that the rotating chuck 22 can pick up and place the workpiece 8 and the rotary cutting tool 15 can cut the workpiece 8.

[0041] In addition, a rotating cylinder 6 is respectively provided at the joint between the loading station 11 and the loading line 4, and at the joint between the unloading station 13 and the unloading line 5. A pneumatic clamp 61 for clamping the workpiece 8 is provided on the rotating part of the rotating cylinder 6. A bottom mold 42 for placing the workpiece 8 is respectively provided in the loading line 4, and the same is true for the unloading line 5. The workpiece 8 is flipped and transferred between the bottom mold 42 and the support table 14 through the rotating cylinder 6.

[0042] It should be noted that, in view of the above-mentioned transfer method, the part to be processed of the workpiece 8 located in the bottom mold 42 of the loading line 4 faces upward. After passing through the rotating cylinder 6 and the rotating chuck 22, the part to be processed is suspended downward to facilitate cutting by the rotary cutting tool 15.

[0043] A waste collection cavity 17 is provided on the workbench 1 and in the central area of ​​the loading station 11, the processing station 12, and the unloading station 13. A waste conveyor 7 docking with the waste collection cavity 17 is provided below the workbench 1, and a transfer trolley 71 is provided at the conveying end of the waste conveyor 7.

[0044] In this regard, the process steps based on the above-mentioned battery shell peeling machine are as follows:

[0045] Step S100: The battery casing workpiece 8 is sequentially placed in the bottom die 42 of the loading line 4, and the workpiece 8 to be processed is ensured to face upwards, and is transferred forward to the rotary cylinder 6. The rotary cylinder 6 clamps the workpiece 8 from the bottom die 42 and turns it 180 degrees, and moves the workpiece 8 to the support table 14 of the loading station 11;

[0046] Step S200: The lifting cylinder 31 at the loading station 11 lifts the support platform 14, so that the workpiece 8 is lifted to the rotary chuck 22 for clamping, and then the support platform 14 is lowered;

[0047] Step S300: The rotary disk 21 rotates 90° and then automatically locks. The rotary chuck 22 drives the workpiece 8 to rotate at high speed. The lifting cylinder 31 at the roughing position 12a lifts the peeling tool 15. The peeling tool 15 rises to cut the workpiece 8 for roughing. After the peeling is completed, the peeling tool 15 is lowered and the rotary chuck 22 is braked to a stop.

[0048] Step S400: The rotary disk 21 rotates 90° and then automatically locks. The rotary chuck 22 drives the workpiece 8 to rotate at high speed. The lifting cylinder 31 at the finishing position 12b lifts the peeling tool 15. The peeling tool 15 rises to cut the workpiece 8 for finishing. After the peeling is completed, the peeling tool 15 is lowered and the rotary chuck 22 is braked to a stop.

[0049] Step S500: The turntable 21 rotates 90° and is automatically locked. The lifting cylinder 31 at the unloading station 13 lifts up the support platform 14, and the rotating chuck 22 releases the workpiece 8, and the workpiece 8 is moved to the support platform 14 of the unloading station 13.

[0050] Step S600: The rotary cylinder 6 at the unloading station 13 clamps the workpiece 8 from the support table 14 and flips it 180 degrees, and moves the workpiece 8 to the bottom mold 42 of the unloading line 5, thereby outputting it from the equipment.

[0051] In addition, if there are multiple workpieces 8 to be processed simultaneously, each workpiece 8 enters the loading station 11 , the processing station 12 and the unloading station 13 simultaneously.

[0052] Therefore, the battery shell peeling machine has the following advantages:

[0053] 1) Higher production efficiency, with an estimated production rate of 50 pieces per minute;

[0054] 2) Less potential safety hazard and safer production;

[0055] 3) Precise movements, smooth cutting surfaces and higher product quality;

[0056] 4) Compact structure, more space-saving, greatly saving equipment costs.
