Description

Technical Field

[0001] The present invention belongs to the field of waste lithium-ion power battery processing, and more specifically, relates to a battery shell and core separation and pushing machine. Background Art

[0002] Against the backdrop of rapid growth in new energy vehicle production and sales, the installed capacity of power batteries continues to rise, and the number of scrapped power and energy storage batteries will also increase rapidly in the coming years. Furthermore, driven by the environmental risks of used batteries and favorable policies, the power battery recycling industry is poised for significant growth.

[0003] Currently, physical crushing is often used to pre-process used prismatic batteries for recycling. This method suffers from mechanical entrainment losses and difficulty achieving complete metal separation and recovery. Therefore, the market requires a refined disassembly method that first separates the battery casing and core, and then separates the casing, positive electrode, negative electrode, and separator within the core to improve the recovery rate of various materials.

[0004] After searching, the Chinese patent application number 202211133059.9 discloses an intelligent platform for disassembling retired batteries. This application includes a mobile chassis and a lifting platform. The lifting platform is fixedly arranged above the mobile chassis. A load-bearing platform is fixedly connected to the top of the lifting platform. The load-bearing platform includes a load-bearing seat and a load-bearing frame. The bottom of the load-bearing seat is connected to the top of the lifting platform. The load-bearing frame is movably connected to the top of the load-bearing seat. The retired batteries are fixed to the load-bearing frame. A number of telescopic adjustment cylinders are arranged between the bottom of the load-bearing frame and the load-bearing seat for connection. The telescopic adjustment cylinders are arranged in a star shape, with one end rotatably connected to the load-bearing seat and the other end rotatably connected to the load-bearing frame. The telescopic adjustment cylinders are communicatively connected to a control unit. The control unit adjusts the extension length of the telescopic adjustment cylinders, thereby tilting the load-bearing frame holding the retired batteries. Although this application can adjust the angle of the retired battery to facilitate disassembly workers, the manual disassembly method used in this application needs to be further improved.

[0005] After searching, the application case with Chinese patent application number 202221086247.6 discloses a new energy vehicle battery disassembly device. The application case includes a disassembly platform and a battery body. The disassembly platform is provided with a support mechanism for placing parts, and a lighting lamp is installed at the bottom of the support mechanism. A first vertical plate is slidably connected to the disassembly platform, and a dust cleaning mechanism is fixedly connected to the upper end of the first vertical plate. The side wall of the first vertical plate is provided with multiple arc-shaped grooves at equal intervals, and the disassembly platform is provided with a positioning mechanism extending into the arc-shaped grooves opposite thereto. Although the application case can firmly fix the battery body to be separated, it does not provide further introduction to the specific separation structure. Summary of the Invention

[0038] The present invention will be further described below with reference to specific embodiments.

[0039] Example 1

[0040] like Figure 1 As shown, in this embodiment, the battery shell core to be separated from the shell and core has completed the cutting of the upper and lower end caps in the previous process. The battery shell core includes a shell 61 and a core 62. Due to the different battery specifications, the size and number of the core 62 are also uncertain. Generally speaking, the thickness of the shell 61 is relatively fixed. The battery shell and core separation is to separate the shell 61 from the core 62. Figure 1 For reference, the length of the battery shell core is the distance along the X-axis, the width of the battery shell core is the distance along the Y-axis, and the height or thickness of the battery shell core is the distance along the Z-axis.

[0041] like Figure 2 As shown, a battery shell core separation and pushing machine of this embodiment includes a frame 1, a conveyor belt 2, a height measuring mechanism 5, an alignment and pressing mechanism 3, and a pushing mechanism 4. Among them, the conveyor belt 2 is arranged on the frame 1, and is responsible for transporting the battery shell core to each processing station. The height measuring mechanism 5 is used to detect the height of the battery shell core, and determine the pushing height of the pushing mechanism 4 according to the actual detection height of the battery shell core of different heights or bulging, to ensure that the shell core can be separated smoothly. The alignment and pressing mechanism 3 aligns and positions the battery shell core before the battery shell core is pushed and separated, to ensure stability during pushing and accuracy of the pushing position. The pushing mechanism 4 is located on the side of the alignment and pressing mechanism 3, and pushes the core body 62 of the battery shell core after limiting, and pushes the core body 62 out of the shell 61 to complete the separation operation of the shell 61 and the core body 62.

[0042] like Figure 3 As shown, the alignment and clamping mechanism 3 includes a support frame 35 and an alignment component and a clamping component arranged on the support frame 35, wherein the alignment component squeezes and adjusts the posture of the battery shell core from both sides of the battery shell core to ensure the accuracy of the pushing position; the clamping component squeezes and limits from the top of the battery shell core to ensure the stability of the battery shell core during the separation process, which is conducive to the effective separation of the core 62 and the shell 61.

[0043] The alignment assembly comprises two adjusting plates 31 arranged oppositely, and the center lines of the two adjusting plates 31 coincide with the center line of the pushing plate 42. The two adjusting plates 31 can move in vertical and horizontal directions, and when moving in the horizontal direction, the two adjusting plates 31 move synchronously to ensure that the position of the center line between the two adjusting plates 31 does not change before and after moving, so that after the two adjusting plates 31 clamp the battery shell core, the center line of the battery shell core coincides with the center line of the pushing plate 42, thereby ensuring the accuracy during pushing.

[0044] Specifically, the adjusting plate 31 is connected with a first driving member 32 and a second driving member 33. The first driving member 32 drives the vertical movement of the two adjusting plates 31, and the second driving member 33 drives the horizontal movement of the two adjusting plates 31. During use, according to the actual height of the battery shell core detected by the height measuring mechanism 5, the first driving member 32 lowers the two adjusting plates 31 to a specified height and positions them on the two sides of the battery shell core, respectively. Then, the second driving member 33 drives the two adjusting plates 31 to move closer to each other, which can adjust the posture of the battery shell core during the movement, and at the same time, the battery shell core is positioned from both sides.

[0045] The pressing assembly comprises a pressing plate 34 and a driving member. The driving member drives the pressing plate 34 to move up and down to press down from the top of the battery shell core, while the adjusting plate 31 positions the battery shell core from both sides, so that the battery shell core can be in a stable state during pushing. The pressing force of the pressing plate 34 should meet the stability of the battery shell core during pushing, and at the same time, should not cause the deformation of the shell 61 to affect the separation of the core 62. Therefore, the structure of the pressing plate 34 is further optimized in this embodiment. The pressing plate 34 is in the shape of an inverted "concave" as a whole. Specifically, the bottom of the pressing plate 34 is provided with an avoiding groove 341, and the two sides of the avoiding groove 341 are contact portions 342. The center line of the pressing plate 34 coincides with the center line of the pushing plate. In this way, when the pressing plate 34 is pressed down, only the contact portions 342 actually generate pressure on the two sides of the top of the shell 61. Since the strength of the two sides of the top of the shell 61 is much greater than the strength of the central part, the deformation of the shell 61 can be effectively avoided.

[0046] In addition, the support frame 35 is provided with a support plate 36. The support plate 36 is connected with the adjusting plate 31 through a first guide rod 37, and the support plate 36 is connected with the pressing plate 34 through a second guide rod 38. The first guide rod 37 and the second guide rod 38 can ensure the stability of the movement of the adjusting plate 31 and the pressing plate 34.

[0047] As shown in FIG. 6, the support plate 36 is provided with a plurality of guide grooves 361, and the adjusting plate 31 is provided with a plurality of guide rods 311. The guide rods 311 are arranged in the guide grooves 361, so that the adjusting plate 31 can move along the support plate 36. Figure 4As shown, the pushing mechanism 4 includes a pushing bracket 41, a pushing plate 42, and a connecting block 45. The connecting block 45 is slidably mounted on the pushing bracket 41, and the sliding engagement can employ a slider or rail structure. A third driving member 43 is provided on the pushing bracket 41, which drives the connecting block 45 to move horizontally, thereby enabling the pushing plate 42 to push the core 62, separating it from the housing 61.

[0048] Due to the inconsistency of battery specifications, the thickness of different battery shell cores varies. In order to adapt to the separation operation of battery shell cores with different thicknesses. Figure 5 、 Figure 6 As shown, in this embodiment, the push plate 42 includes an upper push plate 421 and a lower push plate 422, wherein the upper push plate 421 is connected to a fourth driving member 44, which drives the upper push plate 421 to move up and down. The lower push plate 422 is relatively fixed and can play a certain role in limiting the downward movement of the upper push plate. The fourth driving member 44 and the lower push plate 422 are both disposed on a connecting block 45.

[0049] The end of the push plate 421 is provided with a plurality of notches 423 from top to bottom, and the depth of the notches 423 is greater than the length of the battery shell core to ensure that the core 62 can be completely pushed out of the shell 61 during pushing. At the same time, the height of the notches 423 must be greater than the thickness of the top wall of the shell 61 to ensure that the top wall of the shell 61 can be smoothly inserted into the notches 423.

[0050] During pushing, the lower edge of the lower push plate 422 must be higher than the lower edge of the shell 61. According to the actual thickness of the battery shell core, the fourth driving member 44 drives the upper push plate 421 to rise and fall, adjusting the actual pushing height of the push plate 42. At the same time, it is necessary to ensure that one of the notches 423 on the upper push plate 421 can pass through the upper edge of the shell 61. Then, the third driving member 43 drives the push plate 42 to move, and the upper push plate 421 and the lower push plate 422 jointly push the core 62 to separate the shell 61 from the core 62.

[0051] like Figure 7 As shown, the height measuring mechanism 5 includes a rangefinder 51 and a height measuring plate 52, wherein the rangefinder 51 is located above the height measuring plate 52. The height measuring plate 52 is connected to a fifth driving member 53, which drives the height measuring plate 52 to move up and down. When the height measuring plate 52 presses down and contacts the top of the battery shell core, it stops moving down. The height difference before and after the height measuring plate 52 is pressed down by the rangefinder 51, combined with the starting height of the height measuring plate 52, can be used to obtain the height of the battery shell core. The subsequent pushing mechanism 4 adjusts the height of the upper push plate 421 according to the actual height of the battery shell core to be separated, thereby adapting to the separation of battery shell cores of different specifications.

[0052] In addition, the altimeter mechanism 5 further includes an altimeter frame 54 and a connecting plate 55 arranged on the altimeter frame 54, wherein the rangefinder 51 and the fifth driving member 53 are both arranged on the connecting plate 55, and the altimeter plate 52 and the connecting plate 55 are connected by a third guide rod 56 to ensure the stability of the movement of the altimeter plate 52.

[0053] Specifically in this embodiment, the rangefinder 51 is an optical rangefinder, which detects the height of the height measuring plate 52 to obtain the actual height of the battery shell core, providing data support for the subsequent downward pressing height of the pressing plate 34 and the height adjustment of the push plate 42. In addition, it should be noted that the driving components of this embodiment can adopt existing technologies. As long as they can perform the corresponding functions, they can be used in this embodiment, for example, a cylinder, a motor and a screw.

[0054] The battery shell core separation and pushing machine of this embodiment operates as follows: Multiple groups of cut battery shell cores are transported by conveyor belt 2. When a battery shell core reaches height measuring mechanism 5, conveyor belt 2 stops, and fifth drive member 53 drives height measuring plate 52 downward, pressing against the top of the battery shell core. A rangefinder 51 measures the descending distance of height measuring plate 52. Combined with the starting height of height measuring plate 52, the actual height of the battery shell core is determined and fed back to subsequent processes.

[0055] After the height measuring mechanism 5 completes the inspection, the height measuring plate 52 is raised, and the conveyor belt 2 drives the battery shell core to continue to be conveyed forward. When the battery shell core reaches the alignment and pressing mechanism 3 position, the conveyor belt 2 stops, and the first driving member 32 drives the adjustment plate 31 to descend to the target position. At this point, the two adjustment plates 31 are located on either side of the battery shell core. The second driving member 33 drives the adjustment plates 31 to align and retract, aligning the center of the battery shell core with the center of the push plate 42. The pressing plate 34 then descends, and the contact portion 342 presses against the top of the housing 61.

[0056] Then, according to the detected height of the shell core height, the fourth driving member 44 drives the upper push plate 421 to move, selects the upper push plate 421 and the lower push plate 422 of appropriate height to be combined and maintained, and the third driving member 43 drives the push plate 42 to move to push the core body 62, thereby separating the core body 62 from the shell 61.

[0057] Finally, the adjusting plate 31, the pressing plate 34 and the pushing plate 42 are reset by their respective driving members, and are ready for the next pushing. The shell 61 and the core 62 separated by the pushing are continuously transported to the next station by the conveyor belt 2.

[0058] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
