The drive mechanism comprises two groups of gear rings 31 capable of rotating around the power battery a circumferentially, which is helpful to improve the cutting efficiency of the power battery a and avoid subsequent reprocessing due to partial cutting out of position; the adjusting mechanism is installed on the inner side of the gear ring 31, and the laser cutter 41 is installed on the adjusting mechanism.

[0029] As shown in Figure 1 and Figure 2 , the moving mechanism comprises an electric bidirectional threaded shaft 2, a moving frame 200 and a diamond shaft 201. The electric bidirectional threaded shaft 2 is arranged at the top of the platform 1, and two moving frames 200 are symmetrically distributed in the platform 1 in a sliding manner, and the moving frames 200 are respectively threadedly connected with the electric bidirectional threaded shaft 2.

By controlling the forward and reverse rotation of the electric bidirectional threaded shaft 2, the distance between the two moving frames 200 can be flexibly adjusted to adapt to different models of power batteries a.

[0030] As shown in Figure 1 and Figure 2 , the drive mechanism further comprises a drive motor set 3 and a drive tooth 30. The drive motor set 3 is installed on one side of the top of the platform 1.

By controlling the drive motor set 3, the drive tooth 30 drives the gear ring 31 to rotate, thereby enabling the power battery a to be cut in a ring-shaped bidirectional manner, which can greatly reduce the process of multiple cutting, thereby improving the cutting efficiency.

[0031] As shown in Figures 1 to 3As shown, the adjusting mechanism includes electric slide rails 4, an electric adjusting shaft 40 and an adjusting arm 42, two groups of gear rings 31 are respectively provided with a group of electric slide rails 4, and the laser cutter 41 is slidingly installed on the slide seat of the electric slide rail 4, and the slide seat of the electric slide rail 4 is further provided with the electric adjusting shaft 40, and the slide block of the electric adjusting shaft 40 is hingedly connected with the shell of the laser cutter 41, and the adjusting arm 42 is hingedly connected between the slide block of the electric adjusting shaft 40 and the shell of the laser cutter 41; the electric adjusting shaft 40 is controlled to make the adjusting arm 42 push the laser cutter 41 to move and adjust the position, thereby facilitating the control of the distance between the laser cutter 41 and the power battery a, so as to improve the cutting accuracy.

[0032] As shown in Figure 8 and Figure 9 , the slitting mechanism includes a first linear motor 14, a second linear motor 15, a fixed cutting knife 16 and a movable cutting knife 17, the first linear motor 14 and the second linear motor 15 are symmetrically arranged on the right side of the machine table 1, the second linear motor 15 is connected to the slide block of the first linear motor 14, the first linear motor 14 and the second linear motor 15 are vertically distributed, the second linear motor 15 is provided with the fixed cutting knife 16 on one side, and the movable cutting knife 17 is connected to the slide block of the second linear motor 15; for assisting the split cutting of the power battery a shell, avoiding the situation that part of the shell is adhered and difficult to split, thereby facilitating the subsequent convenient complete split processing.

[0033] As shown in Figure 4 , it further includes a pressing assembly, the pressing assembly includes a first air cylinder 5 and a pressing plate 50, the first air cylinder 5 is installed in the middle of the top of the machine table 1, and the pressing plate 50 is connected to the end of the telescopic shaft of the first air cylinder 5; for providing stable clamping force during cutting of the power battery a, to ensure the cutting accuracy and avoid deviation.

[0034] As shown in Figure 1 , Figure 5 , Figure 6 and Figure 7 , it further includes a conveying assembly, the conveying assembly includes a fixed conveying roller group 6, a movable conveying roller group 60 and a telescopic adjuster 61, the two fixed conveying roller groups 6 are symmetrically arranged on the outer wall of the machine table 1, the movable conveying roller group 60 is movably connected to one side of the fixed conveying roller group 6, and the telescopic adjuster 61 is hingedly connected between the bottom of the movable conveying roller group 60 and the inner bottom of the machine table 1, for controlling the horizontal expansion or downward folding of the movable conveying roller group 60, thereby facilitating the stable connection and conveying of the power battery a.

[0035] As shown in Figure 6As shown, it also includes a limiting component, which includes a guide rod 7 and a positioning plate 70. The fixed conveyor roller group 6 and the moving conveyor roller group 60 are respectively provided with guide rods 7 on the front and rear sides. The positioning plate 70, which can adjust the front and rear distance, is movably connected to the guide rod 7, which is beneficial for the application of different types of power batteries a, and is flexible in use and has a wide range of applications.

[0036] like Figure 7 As shown, the limiting assembly also includes a fixed frame 8, a fixed shaft 9, a spring 10, a movable seat 11, a limiting plate 12, and a pull rod 13. The fixed frame 8 and the fixed shaft 9 are located directly below the pressure plate 50 at the bottom of the machine base 1, and the fixed shaft 9 is located inside the fixed frame 8. A set of fixed conveyor rollers 6 is also provided on the top of the fixed frame 8, and the fixed conveyor rollers 6 are located directly below the pressure plate 50 to receive the power battery a that needs to be cut. The movable seat 11 is movably sleeved on the upper part of the fixed shaft 9, and the movable seat 11 slides in contact with the fixed frame 8. The spring 10 is sleeved on the upper part of the fixed shaft 9, and the two ends of the spring 10 abut against the movable seat 11 and the fixed shaft 9 respectively. Limiting plates 12 are symmetrically distributed on the front and rear sides of the movable seat 11. Pull rods 13 are fixedly connected to the left and right sides of the movable seat 11 respectively. When the movable conveyor rollers 60 flips down and retracts, the pull rods 13 can be pushed down synchronously to make the movable seat 11 and the limiting plate 12 move down synchronously and disengage from the power battery a.

[0037] The power battery a is conveyed to the center area of ​​the moving roller group 60 via the fixed conveyor roller group 6. The positioning plates 70 on both sides can slide horizontally along the guide rod 7 to adjust the spacing, which is used for horizontal guidance and limiting of the power battery a. The pressure plate 50 is driven by the first cylinder 5 to press down to the top of the power battery a, while the limiting plate 12 is raised to abut against the front and rear sides of the power battery a, forming a three-dimensional limiting structure, which helps to improve the stability of the power battery a during cutting. By controlling the rotation of the electric bidirectional threaded shaft 2, the two moving frames 200 are driven to slide horizontally synchronously along the rhomboid axis 201, which can realize convenient adjustment of the spacing between the two moving frames 200. This allows the two sets of laser cutters 41 to correspond to the cutting points on both sides of the power battery a respectively. At this time, the telescopic adjuster 61 can be controlled to retract and fold the connected moving conveyor roller group 60 downward to avoid interference when cutting the power battery a circumferentially. The laser cutter 41 and the drive motor group 3 are started. By controlling the drive motor group 3, the drive tooth 30 drives the tooth ring 31 to rotate, thereby synchronously driving the laser cutter 41 to rotate and cut around the power battery a 360 degrees. The distance between the laser cutter 41 and the power battery a is dynamically adjusted by the electric adjustment shaft 40 through the adjustment arm 42 to keep the beam perpendicular to the surface of the shell.

[0038] When the cutting of the power battery a is completed, the driving motor set 3 and the laser cutter 41 are controlled to suspend work, the first cylinder 5 drives the pressing plate 50 on it to retract and reset upwards, and the telescopic adjuster 61 is controlled to extend to horizontally expand the dynamic conveying roller set 60 connected on it to keep flush with the middle part of the fixed conveying roller set 6. In this process, the limiting plates 12 on the front and rear sides can play a role of horizontal guiding and limiting the power battery a to ensure that the power battery a after cutting can be stably horizontally conveyed to the right side; when the power battery a after cutting is conveyed to the fixed conveying roller set 6 on the right side, the first linear motor 14 on the front and rear sides is controlled to push the dynamic cutting knife 17 into the cutting seam of the power battery a horizontally, and the second linear motor 15 drives the dynamic cutting knife 17 to move away from the fixed cutting knife 16, so as to assist in separating the left and right ends and the upper and lower sides of the shell of the power battery a, avoiding the problem of incomplete cutting of the shell part and causing separation difficulty.

[0039] Specific implementation method two: on the basis of the specific implementation method one, as shown in Figure 1 and Figure 8 The cutting mechanism further includes a guide rod 18, a second cylinder 19, a cutting knife 20, a connecting rod 21 and a guide rail 22. The guide rod 18 is arranged on the right upper part of the machine table 1. The second cylinder 19 is slidably connected to the guide rod 18. The cutting knife 20 is connected to the telescopic shaft of the second cylinder 19. The connecting rod 21 is fixedly connected to the bottom of the cutting knife 20. The guide rail 22 is arranged on the upper side of the dynamic cutting knife 17. The connecting rod 21 is movably arranged in the guide rail 22. When the second linear motor 15 controls the dynamic cutting knife 17 to move, the guide rail 22 drives the connecting rod 21, the cutting knife 20 and the second cylinder 19 to move synchronously.

[0040] In addition, on the basis of assisting in cutting and separating, the second cylinder 19 is controlled to drive the cutting knife 20 to move downward by the extension of the telescopic shaft, so as to cut off the end of the power battery a by the cutting knife 20, so as to achieve the purpose of complete separation. This is conducive to easy processing of the partially adhered part, saving manpower and improving the efficiency of peeling and separating the shell of the power battery a after cutting.

[0041] Specific implementation method three: on the basis of the specific implementation method two, as shown in Figure 10As shown, it also comprises a lifting assembly, which comprises a collecting groove 23, a pushing rod 24 and a lifting plate 25. The pushing rod 24 is horizontally movable and is arranged on the right side of the machine table 1. The lifting plate 25 is rotationally connected to the right side of the fixed conveying roller set 6 and is used to support the power battery a after cutting and needs to be disassembled. The bottom of the lifting plate 25 is hingedly connected to the right end of the pushing rod 24. The machine table 1 is provided with the collecting groove 23 at the lower right side. When the pulling rod 13 on the right side is pressed downward, the pulling rod 24 is pulled to make the lifting plate 25 overturn downward, so that the power battery a after auxiliary disassembly can be automatically unloaded, and the power battery a falls into the collecting groove 23. When the pulling rod 13 is moved upward, the pushing rod 24 pushes the lifting plate 25 to overturn upward and keep horizontal with the right side of the fixed conveying roller set 6.
