Description

[0002] Power batteries are core components of new energy vehicles, primarily the storage batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Currently, waste power battery recycling typically uses a robot with a laser cutting mechanism as the cutting equipment for disassembling the waste power batteries. During disassembly and cutting, the waste power battery is first conveyed under the robot or clamped in a lathe fixture. The robot then uses a laser generator to cut the waste power battery in multiple locations, breaking off the battery casing and facilitating subsequent disassembly.

[0003] However, before laser cutting, existing waste power batteries need to be transported or fixed first. Part of the waste power batteries are usually blocked, which makes it impossible for existing cutting equipment to completely cut them off at one time. Manual or mechanical equipment is also needed to adjust the state of the waste power batteries and cut them again, resulting in low cutting efficiency of the waste power batteries and greater difficulty in subsequent disassembly.

[0004] In view of this, a laser cutting and separation device for waste power battery casings is proposed, which has the function of synchronous circumferential cutting of two sets of laser cutters to improve cutting efficiency, and also has an auxiliary splitting function, in order to solve the above technical problems.

[0028] Specific embodiment 1: The present invention provides a laser cutting and separation device for waste power battery shells, such as Figure 1-10As shown, it includes a machine table 1, a moving mechanism, a driving mechanism, an adjusting mechanism, a laser cutter 41 and a slitting mechanism. The machine table 1 is symmetrically provided with a moving mechanism capable of horizontally adjusting its position. A driving mechanism capable of circumferentially rotating around the power battery a is also provided between the machine table 1 and the moving mechanism. The driving mechanism includes two groups of gear rings 31 capable of circumferentially rotating around the power battery a, which is beneficial to improving the cutting efficiency of the power battery a and avoiding partial incomplete cutting requiring subsequent reprocessing; an adjusting mechanism is installed on the inner side of the gear ring 31, and the laser cutter 41 is installed on the adjusting mechanism. By controlling the adjusting mechanism, the distance between the laser cutter 41 and the power battery a can be flexibly adjusted to ensure that the laser cutter 41 can always be perpendicular to the shell surface of the power battery a, thereby improving the cutting accuracy; a slitting mechanism for separating the cut power battery a shell is also provided on the outer side of the machine table 1.

[0029] like Figure 1 and Figure 2 As shown, the moving mechanism includes 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 machine 1, and the two moving frames 200 are slidingly symmetrically distributed in the machine 1, and the moving frames 200 are respectively threadedly sleeved with the electric bidirectional threaded shaft 2, the diamond shaft 201 is connected to the inner wall of the machine 1 through a bearing, and the moving frame 200 is slidingly sleeved on the diamond shaft 201; 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 types of power batteries a.

[0030] like Figure 1 and Figure 2 As shown, the driving mechanism also includes a driving motor group 3 and driving gears 30. The driving motor group 3 is installed on one side of the top of the machine 1. There are two groups of driving gears 30, which are respectively rotatably connected to the mobile frame 200.

The two groups of ring gears 31 are respectively rotatably connected to the middle of the mobile frame 200, and the driving teeth 30 and the ring gears 31 are engaged with each other; by controlling the driving motor group 3 to realize the driving teeth 30 to drive the ring gear 31 to rotate, the power battery a can be cut in a ring-shaped bidirectional manner, which can greatly reduce the process of multiple cuttings, thereby helping to improve the cutting efficiency.

[0031] like Figures 1 to 3As shown, the adjustment mechanism includes an electric slide rail 4, an electric adjustment shaft 40 and an adjustment arm 42. A group of electric slide rails 4 are respectively installed on the inner sides of the two groups of gear rings 31, and the laser cutter 41 is slidably installed on the slide seat of the electric slide rail 4. The slide seat of the electric slide rail 4 is also provided with an electric adjustment shaft 40. The slider of the electric adjustment shaft 40 is hingedly connected to the shell of the laser cutter 41 with an adjustment arm 42; by controlling the electric adjustment shaft 40, the adjustment arm 42 pushes the laser cutter 41 to move and adjust the position, which is beneficial to control the distance between the laser cutter 41 and the power battery a to improve the cutting accuracy.

[0032] like Figure 8 and Figure 9 As shown, the slitting mechanism includes a first linear motor 14, a second linear motor 15, a fixed dividing knife 16 and a movable dividing knife 17. The first linear motor 14 and the second linear motor 15 are symmetrically arranged on the front and back of the right side of the machine 1, and the second linear motor 15 is connected to the slider of the first linear motor 14. The first linear motor 14 and the second linear motor 15 are vertically distributed. A fixed dividing knife 16 is arranged on one side of the second linear motor 15, and a movable dividing knife 17 is connected to the slider of the second linear motor 15; it is used to assist in splitting the power battery a shell after cutting to avoid partial adhesion and cause difficulty in splitting, which is conducive to subsequent convenient and complete splitting processing.

[0033] like Figure 4 As shown, a clamping assembly is also included, which includes a first cylinder 5 and a pressing plate 50. The first cylinder 5 is installed in the middle of the top of the machine 1, and the end of the telescopic shaft of the first cylinder 5 is connected to the pressing plate 50; it is used to provide a stable clamping force when assisting the cutting of the power battery a to ensure the cutting accuracy and avoid offset.

[0034] like Figure 1 、 Figure 5 、 Figure 6 and Figure 7 As shown, a conveying assembly is also included, which 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 1, and the movable conveying roller group 60 is movably connected to one side of the fixed conveying roller group 6. The bottom of the movable conveying roller group 60 is hingedly connected to the bottom of the machine 1 with a telescopic adjuster 61, which is used to control the movable conveying roller group 60 to expand horizontally or retract downward, thereby facilitating the stable connection and transportation of the power battery a.

[0035] like Figure 6As shown, it also includes a limiting component, which includes a guide rod 7 and a positioning plate 70. The fixed conveying roller group 6 and the movable conveying roller group 60 are respectively provided with guide rods 7 on the front and rear sides. The guide rods 7 are movably connected with a positioning plate 70 that can adjust the front and rear spacing, which is conducive to adapting to different models of power batteries a, and is flexible to use and has a wide range of applications.

[0036] like Figure 7 As shown, the limit assembly also includes a fixed frame 8, a fixed shaft 9, a spring 10, a movable seat 11, a limit plate 12 and a pulling rod 13. A fixed frame 8 and a fixed shaft 9 located directly below the pressure plate 50 are provided at the bottom of the machine 1, and the fixed shaft 9 is located inside the fixed frame 8. A group of fixed conveying rollers 6 are also provided on the top of the fixed frame 8, and the fixed conveying roller group 6 is located directly below the pressure plate 50 for receiving the power battery a that needs to be cut; a movable seat 11 is movably sleeved on the upper part of the fixed shaft 9, and the movable seat 11 is in sliding contact with the fixed frame 8. A spring 10 is sleeved on the upper part of the fixed shaft 9, and the two ends of the spring 10 are respectively abutted on the movable seat 11 and the fixed shaft 9. Limiting plates 12 are symmetrically distributed on the front and back sides of the movable seat 11, and pulling rods 13 are fixedly connected on the left and right sides of the movable seat 11, and when the movable conveying roller group 60 is flipped down and retracted, the pulling rod 13 can be pushed down synchronously to make the movable seat 11 and the limit plate 12 move down synchronously and disengage from the power battery a.

[0037] The power battery a is conveyed to the central area of ​​the movable conveying roller group 60 via the fixed conveying 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 limitation of the power battery a. The first cylinder 5 drives the pressing plate 50 to press down to the top of the power battery a. At the same time, the limiting plate 12 is lifted up to abut the front and rear sides of the power battery a, forming a three-dimensional limiting structure, which is conducive to improving the stability of the power battery a during cutting; by controlling the rotation of the electric bidirectional threaded shaft 2 to drive the two mobile frames 200 to slide synchronously horizontally along the diamond shaft 201, the spacing between the two mobile frames 200 can be conveniently adjusted. The two groups of laser cutters 41 can respectively correspond to the cutting points on both sides of the power battery a; at this time, the telescopic adjuster 61 can be controlled to contract to fold the movable conveying roller group 60 connected thereto downward to avoid interference when the power battery a is cut circumferentially; the laser cutter 41 and the drive motor group 3 are started, and the drive motor group 3 is controlled to make the drive gear 30 drive the gear ring 31 to rotate, thereby being able to synchronously drive the laser cutter 41 to rotate 360 ​​degrees around the power battery a for cutting, and 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 light beam always perpendicular to the surface of the shell.

[0038] When the power battery a is cut, the driving motor group 3 and the laser cutter 41 are controlled to stop working, and the first cylinder 5 is controlled to drive the pressure plate 50 thereon to retract and reset upward, and the movable conveying roller group 60 connected thereto is extended upward and horizontally to be kept flush with the fixed conveying roller group 6 in the middle by controlling the telescopic adjuster 61. During this process, the limit plates 12 on the front and rear sides can play a role of horizontal guidance and limitation for the power battery a, so as to ensure that the cut power battery a can be smoothly transported horizontally to the right; when the power battery a to be cut is transported to the fixed conveying roller group 6 on the right, the first linear motors 14 on the front and rear sides are controlled respectively to push the movable splitting knife 17 to horizontally cut into the cutting seam of the power battery a, and the second linear motor 15 drives the movable splitting knife 17 away from the fixed splitting knife 16, so as to assist in splitting the left and right ends and the upper and lower sides of the shell of the power battery a, thereby avoiding the problem of incomplete cutting of the shell part causing separation difficulty.

[0039] Specific implementation method 2: Based on the specific implementation method 1, Figure 1 and Figure 8 As shown, the slitting mechanism also includes a guide rod 18, a second cylinder 19, a cutter 20, a connecting rod 21 and a guide rail 22. A guide rod 18 is provided on the upper right side of the machine 1, and the second cylinder 19 is slidably connected to the guide rod 18. The telescopic shaft end of the second cylinder 19 is connected to the cutter 20, and the bottom of the cutter 20 is fixedly connected to the connecting rod 21, and guide rails 22 are respectively provided on the upper side of the movable dividing knife 17. The connecting rod 21 is movably arranged in the guide rail 22. When the second linear motor 15 controls the movement of the movable dividing knife 17, the guide rail 22 drives the connecting rod 21, the cutter 20 and the second cylinder 19 to move and adjust synchronously.

[0040] In addition, on the basis of assisting cutting and splitting in the above-mentioned manner, the second cylinder 19 can be controlled to extend its telescopic shaft to drive the cutter 20 to move downward, so that the cutter 20 is pressed down to cut off the end of the power battery a to achieve the purpose of complete separation; this is conducive to the subsequent easy processing of some adhesions, which is conducive to saving manpower and improving the efficiency of peeling and splitting the power battery a shell after cutting.

[0041] Specific implementation method three: Based on the specific implementation method two, Figure 10As shown, it also includes a lifting component, which includes a collection trough 23, a lever 24 and a lifting plate 25. A lever 24 that can be horizontally moved and adjusted is provided on the right side of the machine 1. The lifting plate 25 is rotatably connected to the fixed conveying roller group 6 on the right side, and is used to support the power battery a whose shell needs to be disassembled after cutting. The bottom of the lifting plate 25 is hinged to the right end of the lever 24, and a collection trough 23 is provided at the lower right side of the machine 1; when the pull rod 13 on the right side is pressed down, the lever 24 will be pulled to make the lifting plate 25 flip downward, so that the power battery a shell after assisted disassembly can be automatically unloaded, so that the power battery a shell falls into the collection trough 23; and when the pull rod 13 moves upward, it will drive the lever 24 to push the lifting plate 25 to flip upward and expand to keep it level with the fixed conveying roller group 6 on the right side.
