Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery recycling, in particular to a device for separating the shell and the inner core of a scrapped power battery. BACKGROUND

[0002] Since the 21st century, the development of new energy vehicles has been regarded as an extremely important work by countries all over the world. The mass popularization of pure electric vehicles in the market has led to an increasing number of manufacturers of power batteries, the core components of the vehicles, which will inevitably result in a large number of scrapped power batteries in the coming years. Efficient recycling of the waste power batteries will bring great environmental and economic benefits. Therefore, it is increasingly important to strengthen the recycling of the scrapped power batteries.

[0003] For the battery recycling process, the positive and negative electrode materials in the waste power batteries have the highest recycling value. However, the whole battery crushing will result in insufficient purity of the recycling products, thereby greatly reducing the economic benefits. Manual cutting of the battery will lead to long time consumption and high cost due to the discontinuous cutting and core extraction process, and it is difficult to meet the future large recycling demand. Therefore, it is urgent to provide a device for separating the shell and the inner core of a scrapped power battery to solve the above problems, so as to realize the mechanization and non-crushing disassembly of the scrapped power battery.

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] Please see Figures 1 to 12A device for separating the outer casing and inner core of a waste power battery includes a workbench 4. The workbench 4 is a frame structure welded from structural steel. The top of the frame is equipped with a work surface, which is installed for the installation of various functional units for the dismantling of waste power batteries, through any mechanical fixing method such as bolts or welding. The bottom of the workbench 4 is equipped with an electrical control cabinet and a pneumatic system (not shown in the figure). Since this equipment only involves the logical control of the mechanical movement of power output components such as servo motors, AC motors, and cylinders, a general electrical equipment control system is selected, and the corresponding control program is preset in the control system. Its structural composition and working principle are existing technologies and will not be described in detail here.

[0043] A clamping unit 1 is provided on one side of the top of the workbench 4, such as... Figure 1 and Figure 2 As shown, the clamping unit 1 includes a battery pack clamping frame transmission mechanism 12 and a battery pack clamping frame assembly 11 mounted on the power actuation end of the battery pack clamping frame transmission mechanism 12. The battery pack clamping frame assembly 11 is used for assembling and clamping the power batteries to be separated. The battery pack clamping frame transmission mechanism 12 is used to drive the battery pack clamping frame assembly 11 to move back and forth and to position the battery pack clamping frame assembly 11 at the working positions of the cell separation unit 3, the housing unloading unit 5, and the disassembly and cutting unit 2, respectively. Specifically, the battery pack clamping frame transmission mechanism 12 is a ball screw linear module driven by a servo motor, horizontally mounted on the top front side of the worktable 4, and its effective stroke covers the working positions of the cell separation unit 3, the housing unloading unit 5, and the disassembly and cutting unit 2.

[0044] like Figures 5 to 7 As shown, the battery pack clamping frame assembly 11 includes a base plate 111, an outer frame 112 fixedly disposed on the top surface of the base plate 111, and an inner frame 113 detachably placed inside the outer frame 112. The power actuation end of the battery pack clamping frame transmission mechanism 12 is fixedly connected to a horizontally movable horizontal positioning plate 13. The base plate 111 is fixedly connected to the top surface of the horizontal positioning plate 13 by bolts. The outer frame 112 is a square groove structure with a "U" shaped cross section. Horizontal flanges are provided on the top two sides of the square groove. The inner frame 113 is a square shell structure with open front and rear sides. The inner frame 113 can be movably placed inside the outer frame 112 from the front side of the outer frame 112, and the inner frame 113 can also be removed from the outer frame 112 from this side. Preferably, a positioning plate 1121 is provided on one side (rear side) of the bottom wall of the outer frame 112. When the inner frame 113 is placed inside the outer frame 112 and pushed to the innermost position, the rear side of the bottom wall of the inner frame 113 abuts against the inner side of the positioning plate 1121, thereby achieving accurate positioning of the inner frame 113 inside the outer frame 112.

[0045] Lifting cylinders 114 are fixedly installed on both sides of the outer wall of the outer frame 112 (specifically, on the bottom surface of the horizontal flanges). The output shaft ends of the lifting cylinders 114 are fixedly connected to pressure plates 115 located above the inner frame 113. The pressure plate 115 has an inverted "U" shaped cross section, and horizontal flanges are provided on the outer sides of the bottom ends of its two side walls. The output shaft ends of the two lifting cylinders 114 are fixedly connected to the bottom surfaces of the two flanges of the pressure plate 115. The distance between the inner walls of the two sides of the pressure plate 115 matches the outer length dimension of the inner frame 113. When the two lifting cylinders 114 simultaneously drive the pressure plate 115 to descend, the pressure plate 115 can be locked onto the top outer side of the inner frame 113, thereby securing the inner frame 113 inside the outer frame 112. When the two lifting cylinders 114 move in opposite directions to drive the pressure plate 115 to rise, the pressure plate 115 is suspended above the inner frame 113, at which point the inner frame 113 can be removed from the outer frame 112.

[0046] A lower clamping plate 116 is fixedly installed on the inner bottom surface of the inner frame 113. An upper clamping plate 117 is movably installed inside the inner frame 113, located above the lower clamping plate 116. Before using this equipment to dismantle the scrapped power batteries, the scrapped power batteries that have undergone discharge treatment need to be manually assembled inside the inner frame 113. During assembly, the scrapped power batteries are stacked horizontally in the inner frame 113 with the terminals facing outwards, and each scrapped power battery is positioned between the upper clamping plate 117 and the lower clamping plate 116. Preferably, several springs 119 are fixedly connected between the top surface of the upper clamping plate 117 and the top inner wall of the inner frame 113. After the scrapped power battery is placed between the upper clamping plate 117 and the lower clamping plate 116, the springs 119 are in a compressed state. Under the elastic reaction of the springs 119, the upper clamping plate 117 presses each scrapped power battery onto the lower clamping plate 116, thereby completing the initial clamping and positioning of the scrapped power battery inside the inner frame 113.

[0047] Preferably, both the lower clamping plate 116 and the upper clamping plate 117 are made of rubber material, and protrusions (in this embodiment, toothed strip protrusions) are provided on the opposite sides of the lower clamping plate 116 and the upper clamping plate 117, and the projections of the strip protrusions on the lower clamping plate 116 and the upper clamping plate 117 in the horizontal plane are alternately distributed. After each scrapped power battery is clamped between the lower clamping plate 116 and the upper clamping plate 117, the protrusions on the lower clamping plate 116 and the upper clamping plate 117 undergo slight deformation to clamp the scrapped power battery. The front side of the bottom of the upper clamping plate 117 is provided with a bevel. When the scrapped power battery is horizontally pushed into the inner frame 113 from the front side, the top edge of the scrapped power battery acts on the bevel, and the vertical component of the pushing force can push the upper clamping plate 117 upward, so that the scrapped power battery can smoothly enter the lower part of the upper clamping plate 117.

[0048] At least one (as shown in this embodiment) is fixedly provided on the bottom surface of the pressure plate 115. Figure 7The two pressure columns 118 shown are movable through the top sidewall of the inner frame 113 and press against the top surface of the upper clamping plate 117. When the two lifting cylinders 114 drive the pressure plate 115 to descend and secure the inner frame 113 to the outer frame 112, the two pressure columns 118 move downwards and press down on the upper clamping plate 117, thus completing the complete clamping and positioning of the scrapped power battery within the inner frame 113. In this embodiment, 10 scrapped power batteries can be filled into the inner frame 113 at a time. The clamping state of the scrapped power batteries within the inner frame 113 is as follows: Figure 8 As shown.

[0049] On the top surface of the workbench 4, a cell separation unit 3 and a housing unloading unit 5 are respectively arranged on one side of the clamping unit 1. At the top of the workbench 4, a disassembly and cutting unit 2 is arranged between the cell separation unit 3 and the housing unloading unit 5, above the clamping unit 1. The disassembly and cutting unit 2 includes a saw blade milling cutter lifting mechanism 21 and a saw blade milling cutter assembly 22 mounted on the power execution end of the saw blade milling cutter lifting mechanism 21. The saw blade milling cutter lifting mechanism 21 is used to drive the lifting and lowering of the saw blade milling cutter assembly 22, and the saw blade milling cutter assembly 22 is used for cutting both ends of the power battery housing to be separated.

[0050] Specifically, the saw blade milling cutter lifting mechanism 21 includes a gantry frame fixedly mounted on the top surface of the worktable and a ball screw linear module driven by a servo motor fixedly mounted on the gantry frame. This linear module is vertically arranged. For example... Figure 9 As shown, the saw blade milling cutter assembly 22 includes a drive motor 221, a cutter shaft 224 fixedly mounted on the output shaft end of the drive motor 221, a fixed saw blade milling cutter 222 fixedly mounted on the inner end of the cutter shaft 224, and a movable saw blade milling cutter 223 adjustablely mounted on the outer end of the cutter shaft 224. A vertically movable vertical positioning plate 23 is fixedly connected to the power execution end of the saw blade milling cutter lifting mechanism 21. An inverted "U"-shaped motor mounting bracket 24 is fixedly connected to the side of the vertical positioning plate 23. The drive motor 221 is fixedly mounted on one end of the back side of the motor mounting bracket 24, and the output shaft of the drive motor 221 is horizontally positioned and perpendicular to the direction of movement of the battery pack clamping frame assembly 11. A bearing seat 25 is fixedly connected to the bottom of the front end of the motor mounting bracket 24. The cutter shaft 224 is horizontally positioned, with one end connected to the output shaft end of the drive motor 221 via a coupling, and the other end rotatably mounted in the bearing seat 25 via a bearing.

[0051] The fixed saw blade end mill 222 and the movable saw blade end mill 223 are coaxially mounted on the tool shaft 224, meaning they are arranged parallel to each other. A first positioning sleeve 225 and a second positioning sleeve 226 are threaded onto the tool shaft 224. The movable saw blade end mill 223 is located between the first positioning sleeve 225 and the second positioning sleeve 226. By synchronously adjusting the threaded connection positions of the first positioning sleeve 225 and the second positioning sleeve 226 on the tool shaft 224, the axial position of the movable saw blade end mill 223 on the tool shaft 224 can be adjusted, thereby adjusting the distance between the movable saw blade end mill 223 and the fixed saw blade end mill 222 to meet the cutting needs of both ends of waste power battery casings of different lengths. In this embodiment, both the movable saw blade milling cutter 223 and the fixed saw blade milling cutter 222 are located about 3cm inside the end of the casing of the scrapped power battery. When the drive motor 221 drives the fixed saw blade milling cutter 222 and the movable saw blade milling cutter 223 to rotate synchronously, and the saw blade milling cutter lifting mechanism 21 drives the fixed saw blade milling cutter 222 and the movable saw blade milling cutter 223 to move downwards, the fixed saw blade milling cutter 222 and the movable saw blade milling cutter 223 simultaneously perform cutting operations on both ends of the casing of the scrapped power battery. After the cutting operation is completed, the saw blade milling cutter lifting mechanism 21 then drives the fixed saw blade milling cutter 222 and the movable saw blade milling cutter 223 to rise and reset in the opposite direction.

[0052] The cell separation unit 3 includes a push rod transmission mechanism 31 and a push rod assembly 32 mounted on the power actuation end of the push rod transmission mechanism 31. The push rod transmission mechanism 31 drives the push rod assembly 32 to move horizontally and reciprocally, and the push rod assembly 32 pushes the cell out of the cut power battery casing. The push rod transmission mechanism 31 also uses a servo motor-driven ball screw linear module. Figure 10 As shown, the push rod assembly 32 includes a mounting plate 321, multiple sets (the same number as the number of scrapped power batteries clamped in the inner frame 113, 10 sets in this embodiment) of push rods 322 fixedly disposed on the side of the mounting plate 321 and arranged linearly and evenly, and push plates 323 fixedly disposed at the ends of each set of push rods 322. Each push plate 323 can be movably inserted into each cut power battery casing in the inner frame 113. The mounting plate 321 is fixedly installed on the power actuation end of the push rod transmission mechanism 31. The push rod transmission mechanism 31 can drive the mounting plate 321 to move closer to or away from the battery pack clamping frame assembly 11, so that the push plates 323 can be inserted into or removed from the inner frame 113 accordingly.

[0053] Preferably, the length of the push rod 322 is not less than the length of the cut power battery casing, the outer contour of the push plate 323 matches the internal cross-sectional shape of the cut power battery casing, and the horizontal center distance between two adjacent push plates 323 is equal to the horizontal center distance between two adjacent scrapped power batteries in the inner frame 113. This ensures that when the battery pack clamping frame assembly 11 is positioned in the working position of the cell separation unit 3, the push rod transmission mechanism 31 drives the push plate 323 to insert into the interior of the battery casing that has been cut at both ends. Thus, the push plate 323 can completely push the cell out of the battery casing and allow it to fall naturally. Then, the push rod transmission mechanism 31 drives the push plate 323 to reset in the opposite direction, completing the separation of the cell from the battery casing. At this time, the battery casing still remains inside the battery pack clamping frame assembly 11.

[0054] The casing unloading unit 5 is used for the automatic unloading of the power battery casing after the battery cells have been removed. For example... Figure 11 As shown, the housing unloading unit 5 includes a cylinder bracket 51, a push-pull cylinder 52 fixedly installed on the top of the cylinder bracket 51, and a thrust plate 53 fixedly installed on the output shaft end of the push-pull cylinder 52. The thrust plate 53 can be movably inserted into the inner frame 113, and the outer contour of the thrust plate 53 matches the internal cross-sectional shape of the inner frame 113 (i.e., it is a square plate). The effective stroke of the push-pull cylinder 52 is not less than the width of the inner frame 113 in the direction of movement of the thrust plate 53. During the assembly of the scrapped power batteries in the battery pack clamping frame assembly 11, the push-pull cylinder 52 is in the maximum return position, and the thrust plate 53 is located inside the inner frame 113. By pushing the scrapped power batteries horizontally inward, the inner end of the casing of the scrapped power batteries can be made to abut against the side of the thrust plate 53, thereby achieving accurate positioning of each scrapped power battery in the inner frame 113. Then, the lifting cylinder 114 drives the pressure plate 115 to descend, thereby accurately positioning and fastening the scrapped power batteries in the inner frame 113 to ensure that the scrapped power batteries are in the accurate cutting position. After the separation of the battery cell from the battery casing is completed at the working position of the cell separation unit 3, the battery pack clamping frame transmission mechanism 12 drives the battery pack clamping frame assembly 11 to move in the reverse direction and position it at the working position of the casing unloading unit 5. At this time, the lifting cylinder 114 drives the pressure plate 115 to rise, so that the pressure plate 115 releases the clamping effect on the upper clamping plate 117. Then, the push-pull cylinder 52 moves forward to its maximum stroke, driving the thrust plate 53 into the inner frame 113. The side of the thrust plate 53 pushes each battery casing out of the inner frame 113. Then, the push-pull cylinder 52 moves in the reverse direction to reset the thrust plate 53, thereby completing the automatic unloading of the cut battery casing.

[0055] The workbench 4 is also equipped with a product collection unit 6 located on one side of the working position of the disassembly and cutting unit 2. The product collection unit 6 includes a fan 61 fixedly installed on the top surface of the workbench 4, and battery casing end collection boxes 62, cell collection boxes 63, and battery casing collection boxes 64 respectively installed on one side of the workbench 4.Figure 12 As shown, the exhaust fan 61 is fixedly connected to a pipe 65 at its outlet. The end of the pipe 65 is connected to a dust collection box 66 located on one side of the workbench 4. The dust collection box 66 is equipped with a dust collection bag or an adsorbent and other dust treatment devices. When the disassembly and cutting unit 2 is cutting the scrapped power battery, the exhaust fan 61 is working. The negative pressure airflow draws the dust and harmful gases generated during cutting into the dust collection box 66 to prevent dust from spreading and affecting the working environment, and to reduce the harm to the operator's health. The battery casing end collection box 62 is located directly below the working position of the dismantling and cutting unit 2. When the dismantling and cutting unit 2 performs the cutting operation on the scrapped power battery, the cut-off battery casing ends naturally fall into the battery casing end collection box 62. The cell collection box 63 is located directly below the working position of the cell separation unit 3. When the cell separation unit performs the cell and casing separation operation on the cut scrapped power battery, the cells pushed out from the battery casing naturally fall into the cell collection box 63. The battery casing collection box 64 is located directly below the working position of the casing unloading unit 5. When the casing unloading unit 5 performs the unloading operation on the battery casing after the cells have been removed, the battery casing pushed out from the inner frame 113 naturally falls into the battery casing collection box 64, thereby completing the separate automatic collection of dismantling products.

[0056] The process of dismantling obsolete power batteries using this device is as follows:

[0057] (1) The operator pre-installs 10 scrapped power battery cells to be cut in the inner frame 113, and then puts the inner frame 113 containing the scrapped power batteries to be cut into the outer frame 112, and pushes the scrapped power batteries against the thrust plate 53 to complete the positioning of the scrapped power batteries in the battery pack clamping frame assembly 11; the lifting cylinder 114 works in the forward direction, driving the pressure plate 115 to descend and clamp the scrapped power batteries in the battery pack clamping frame assembly 11;

[0058] (2) The battery pack clamping frame transmission mechanism 12 drives the battery pack clamping frame assembly 11 to the working position of the disassembly and cutting unit 2. The drive motor 221 works, driving the fixed saw blade milling cutter 222 and the movable saw blade milling cutter 223 to rotate synchronously. The saw blade milling cutter lifting mechanism 21 drives the fixed saw blade milling cutter 222 and the movable saw blade milling cutter 223 to descend, and simultaneously cut both ends of the casing of the scrapped power battery. After the cutting is completed, the saw blade milling cutter lifting mechanism 21 drives the fixed saw blade milling cutter 222 and the movable saw blade milling cutter 223 to rise and reset. The drive motor 221 stops working, and the cut battery casing ends fall naturally into the battery casing end collection box 62.

[0059] (3) During the cutting operation, the exhaust fan 61 works to adsorb the dust and harmful gases generated during the cutting operation and discharge them into the dust collection box 66 for treatment.

[0060] (4) After the cutting operation is completed, the battery pack clamping frame transmission mechanism 12 drives the battery pack clamping frame assembly 11 to move to the working position of the cell separation unit 3. The push rod transmission mechanism 31 works in the forward direction, drives the push plate 323 to insert into each cut battery shell, pushes out the cells in the battery shell, and then the push rod transmission mechanism 31 works in the reverse direction, drives the push plate 323 to reset, and the cells pushed out from the battery shell naturally fall into the cell collection box 63.

[0061] (5) After the separation of the battery cell and the battery casing is completed, the battery pack clamping frame transmission mechanism 12 drives the battery pack clamping frame assembly 11 to move to the working position of the casing unloading unit 5. At this time, the lifting cylinder 114 drives the pressure plate 115 to rise, so that the pressure plate 115 releases the clamping effect on the upper clamping plate 117. Then the push-pull cylinder 52 moves forward to the maximum stroke, driving the thrust plate 53 into the inner frame 113. The side of the thrust plate 53 pushes each battery casing out of the inner frame 113. Then the push-pull cylinder 52 moves in the opposite direction to reset the thrust plate 53, thereby completing the automatic unloading of the cut battery casing. The battery casing pushed out from the inner frame 113 naturally falls into the battery casing collection box 64.

[0062] (6) Then, the battery pack clamping frame transmission mechanism 12 drives the battery pack clamping frame assembly 11 to move to the initial loading position and repeats the above process (1)-(5) to continue to complete the dismantling operation of the next set of scrapped power batteries.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
