Description

Technical Field

[0001] The invention relates to the technical field of battery cell shell production, and in particular to a double-head rotary cutting device for battery cell shells. Background Art

[0002] like Figure 8 As shown in the figure, the battery cell housing 5 is produced and processed in the prior art. The battery cell housing 5 is formed into a hollow rectangular parallelepiped by bending an aluminum plate in half, and the two sides of the aluminum plate are welded and fixed after bending.

[0003] At present, in the production process, it is necessary to perform peeling on the openings at the left and right ends of the hollow and rectangular battery cell shell. Existing peeling equipment, for example, a fully automatic double-head peeling machine for new energy battery boxes disclosed in a Chinese invention patent (publication number CN116238007A), comprises a frame, a material frame is provided on the frame, a guide light axis seat is provided on the frame, an outer cutting knife module is movably connected to the guide light axis seat, a peeling module is movably connected to the inner cutting knife module, the peeling module is fixedly connected to a linear pushing mechanism, the linear pushing mechanism is fixedly connected to the frame, a wall breaking driving mechanism is provided on the peeling module, and a peeling driving mechanism is provided on the peeling module; an elastic component is provided on the peeling module, and the elastic component is movably connected to the outer cutting knife module.

[0004] The rotary cutter is driven by hydraulic rotation combined with the rotation of the eccentric wheel to drive the rotary cutter to perform rotary cutting along the inner peripheral wall of the end opening of the battery shell 5. Since the hydraulic driving method is subjected to relatively large force, the wear between the rotary cutter and the battery shell 5 is relatively large, causing the battery shell 5 to be deformed due to mold extrusion, resulting in a large rotary cutting size error. At the same time, due to the movement of the eccentric wheel, the motion trajectory of the rotary cutter is fixed and cannot be adjusted. After a period of use, the eccentric wheel or the rotary cutter will cause a certain degree of wear, which will cause the rotary cutting trajectory of the rotary cutter to change. Since the rotary cutting trajectory cannot be directly adjusted manually, the entire rotary cutting structure must be adjusted and maintained manually every once in a while. Each adjustment and maintenance process is time-consuming and labor-intensive, resulting in low efficiency of the entire rotary cutting process and increased consumables, affecting the overall production cost and production efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the existing peeling equipment has large losses and low precision through the eccentric wheel, and also requires manual parameter adjustment frequently, which affects the peeling efficiency and peeling quality. In order to overcome the above defects of the prior art, the present invention provides a peeling structure that combines the vertical moving positioning part and the front and rear moving positioning part in the peeling floating positioning assembly to replace the existing eccentric wheel peeling structure, reduce losses, improve precision, and facilitate adjustment of the parameters of the peeling tool through a combination of horizontal and vertical methods, greatly improving the convenience of adjustment, and improving the overall peeling efficiency and peeling quality.

Through the holding grooves 24 on the first holding support plate 22 and the second holding support plate 23, the battery cell shell 5 can be placed horizontally, and both ends of the battery cell shell 5 can extend beyond the first holding support plate 22 and the second holding support plate 23. At the same time, the holding clamping cylinder 25 drives the holding clamping plate 26 to press the battery cell shell 5 against one side of the holding groove 24, thereby preventing the battery cell shell 5 from being displaced during the peeling process, thereby ensuring stability and firmness during the peeling process.

[0039] like Figure 1 As shown, the rack 1 is provided with waste recycling openings 11 for the waste to fall after peeling at both ends of the battery cell housing 5; a waste conveyor belt 12 is provided on the rack 1 below the waste recycling opening 11, and a waste recycling box 13 is provided at the discharge end of the waste conveyor belt 12. The above structure facilitates the unified recycling of the waste after peeling, which is convenient for subsequent processing.

[0040] When the device is peeling, the cell shell 5 is grabbed by the manipulator and transferred to the shell holding mechanism 2, so that the cell shell 5 is placed horizontally in the left and right directions, and the left and right ends of the cell shell 5 are both beyond the first holding support plate 22 and the second holding support plate 23. When the photoelectric sensor 27 detects that the cell shell 5 has been placed, it transmits a signal to the holding clamping cylinder 25, and the holding clamping cylinder 25 drives the holding clamping plate 26 to move toward the cell shell 5, so that the cell shell 5 is pressed against the holding grooves 24 of the first holding support plate 22 and the second holding support plate 23, to ensure that the cell shell 5 is stably and firmly clamped and fixed, and prevent the cell shell 5 from being displaced during the peeling process at both ends.

[0041] After the battery cell shell 5 is positioned, the first peeling mechanism 3 and the second peeling mechanism 4 are moved relatively toward the battery cell shell 5, and the peeling sliding motor 401 on the peeling sliding part 40 drives the peeling sliding shaft 402 to rotate, thereby driving the peeling bracket 41 on the peeling sliding platform 403 to move horizontally, so that the two ends of the battery cell shell 5 are respectively inserted into the peeling positioning through holes 410 on the peeling brackets 41 on both sides, so that the first peeling mechanism 3 and the second peeling mechanism 4 perform preliminary positioning on the two ends of the battery cell shell 5, and then the peeling floating frame 431 is driven to move by two horizontal positioning cylinders 421, so that the peeling tool head 442 of the peeling tool 44 is inserted into the opening at the end of the battery cell shell 5, thereby realizing the positioning of the peeling tools 44 on the first peeling mechanism 3 and the second peeling mechanism 4 and the openings at both ends of the battery cell shell 5.

[0042] After the rotary cutting tool 44 is positioned, the rotary cutting tool 44 is rotated along the inner peripheral wall of the opening at the end of the battery shell 5 through the vertical moving positioning part and the front-to-back moving positioning part in the rotary cutting floating positioning assembly 43, so as to rotary cut the end of the battery shell 5. The vertical moving positioning part and the front-to-back moving positioning part of the present application can adjust the motion trajectory of the rotary cutting tool 44 in the vertical and front-to-back directions by adopting the servo motor driven positioning method, so that the motion trajectory parameters can be adjusted to the optimal state according to the actual production process, which changes the disadvantage that the existing hydraulic drive eccentric wheel trajectory cannot be adjusted, and in the actual production process, the rotary cutting tool head 442 and the eccentric wheel will be worn after a certain number of rotary cutting, resulting in the irreversible defect of eccentric wheel wear, thereby affecting the motion trajectory of the rotary cutting tool head 442, and finally affecting the rotary cutting accuracy and rotary cutting quality. However, the present application can adjust the rotary cutting trajectory in real time through the vertical moving positioning part and the front-to-back moving positioning part, so as to adjust the optimal rotary cutting trajectory required for production at that time, and does not need maintenance and disassembly adjustment like the eccentric wheel structure. The structure of the present application is more flexible and convenient, and has higher adaptability.

[0043] In summary, the advantages of the present invention are: 1. The present application changes the original hydraulically driven structure into a pneumatic structure. Since the large hydraulic pressure easily causes large wear, the horizontal positioning cylinder 421 is more suitable for the peeling process.

[0044] 2. The present application changes the original eccentric wheel peeling structure into a servo motor adjustment structure. Since the structural trajectory of the eccentric wheel is fixed and irreversible, it will cause wear after a period of use, affecting the peeling accuracy. The present application can adjust the peeling trajectory of the peeling tool 44 in real time through the vertically movable positioning part and the front and rear movable positioning part. The adjustment is more convenient, fast and flexible, and the peeling quality can also be ensured.

[0045] 3. The housing grooves 24 of the first housing support plate 22 and the second housing support plate 23 on the housing housing holding mechanism 2 of the present application facilitate the placement of the battery cell housing 5. At the same time, the housing clamping plates 26 on the housing clamping cylinder 25 facilitate the clamping and fixing of the battery cell housing 5, thereby preventing the battery cell housing 5 from being displaced during the peeling process, thereby ensuring stability and firmness during the peeling process.

[0046] 4. The present application facilitates the collection and recycling of peeled waste by means of the waste conveyor belt 12 and the waste recycling box 13, eliminating the need for manual cleaning and thus improving the cleanliness of the entire equipment.
