Description

[0002] Power batteries refer to batteries with large electrical capacity and output power, which can be used as driving power sources for electric bicycles, electric vehicles, electric equipment and tools. With the gradual increase in the production and sales of new energy vehicles, the power battery market is showing a rapid growth trend, which also means that power batteries are about to enter a large-scale scrap period. The recycling of scrapped batteries has become an important factor affecting the development of the power battery industry. Improper recycling of waste batteries will aggravate the global environmental pollution problem.

[0003] At present, my country is still in the research stage of recycling scrapped power batteries. The degree of automated disassembly of power batteries is low, and a large part of the disassembly of power batteries still relies on manual work, which is not only inefficient, but also causes safety hazards and endangers human health if operated improperly. Enterprises have been seeking more efficient, universal and safe disassembly methods.

[0004] The use of automatic recycling equipment has solved the problem of low disassembly efficiency to a certain extent. However, because the inner core of the power battery is wrapped in the outer shell, the existing automatic recycling equipment mostly puts the battery pack into the crushing device for mechanical crushing, and then screens the processed materials. This method is often difficult to effectively separate the debris and is costly. The inner core structure is also easily damaged during the crushing process, which can easily cause a series of safety problems. Therefore, it is very necessary to design a set of efficient, complete, and easy-to-operate battery shell disassembly equipment without destroying the inner core structure. Summary of the invention

Figure 6 shown.

[0040] The clamping mechanism 5 is composed of four groups of positioning push rods 51 , which are arranged in a cross shape and are respectively arranged on one of the beams of the square frame on the top of the frame 1 .

[0041] The positioning push rod 51 is composed of a fixed plate 511, a push rod cylinder 512 and a positioning push plate 513. The fixed plate 511 is fixedly connected to the bottom surface of the beam frame on the corresponding side, one end of the push rod cylinder 512 is fixedly connected to the top surface of the outer end of the fixed plate 511, and the inner end of the cylinder shaft is connected to a positioning push plate 513.

[0042] Pressure sensors are provided on the positioning push plates 513 on the two transverse beams of the square frame connected to the top of the frame 1.

[0043] The horizontal cutting assembly 6 includes a fixed frame 61, a moving beam 62, a horizontal cutting tool connecting member 63 and a horizontal cutting tool 64.

A cylinder 2 68 is arranged at one end of the bottom of the moving beam 62. The piston rod end of the cylinder 2 68 is connected to the horizontal cutting tool connecting piece 63. The horizontal cutting tool connecting piece 63 can slide along the translation operation under the action of the cylinder 2 68. The horizontal cutting tool 64 is movably connected to the bottom of the horizontal cutting tool connecting piece 63. The horizontal cutting tool 64 is controlled by a motor to perform high-speed rotation cutting.

[0044] The vertical cutting assembly 7 includes a bottom movable beam 71, a vertical beam frame 72, a vertical cutting tool connecting piece 73 and a vertical cutting tool 74. The setting direction of the bottom movable beam 71 is parallel to the conveying direction of the conveyor belt. The bottom of the vertical beam frame 72 is slidably connected to the bottom movable beam 71. A cylinder 3 75 is provided at the outer end of the bottom movable beam 71. The piston rod end of the cylinder 3 75 is connected to the outer side surface of the vertical beam frame 72. The vertical beam frame 72 can slide along the setting direction of the bottom movable beam 71 under the action of the cylinder 3 75. A longitudinal tool guide groove 76 is provided inside the frame 72, and a vertical cutting tool connecting piece 73 is connected in the tool guide groove 76. A cylinder 4 77 is provided on the top of the vertical beam frame 72, and the piston rod end of the cylinder 4 77 is connected to the top of the vertical cutting tool connecting piece 73.

[0045] The vertical cutting tool 74 and the horizontal cutting tool 64 used in this embodiment both adopt high-speed cutting heads. The high-speed cutting technology can greatly reduce the incision temperature. When the rotation speed is higher than the heat transfer speed, the heat will be taken away with the chips, avoiding safety problems caused by high temperature of the battery.

[0046] The auxiliary transmission mechanism 8 includes a working platform 81, an angle adjustment mechanism 82, a rotating motor 83, a hydraulic cylinder 84 and a base 85 which are arranged in sequence from top to bottom. The hydraulic cylinder 84 is fixedly connected to the base 85, the push rod shaft at the top of the hydraulic cylinder 84 is connected to the rotating motor 83, and the motor shaft end at the top of the rotating motor 83 is connected to the angle adjustment mechanism 82.

[0047] The angle adjustment mechanism 82 includes a platform connecting rod 821 and a push cylinder 822. The end of the platform connecting rod 821 is hingedly connected to the bottom of the working platform 81. The push cylinder 822 is obliquely connected to the platform connecting rod 821. The end of the piston rod of the push cylinder 822 is connected to the bottom surface of the working platform 81.

[0048] A group of thrust plates 813 are provided in the hole groove on the side of the working platform 81 away from the inlet conveyor belt 2. A pressure sensor is provided on the thrust plate 813. The thrust plate 813 is controlled to open and close by a solenoid valve. When power is turned on, the two thrust plates 813 rotate toward each other and close. At this time, the top of the thrust plate 813 will move downward in the vertical direction during the rotation and closing process until it retracts to a position lower than the top surface of the working platform 81 to avoid position interference with the right positioning push rod 51 when the power is turned off. When the power is turned off, the two thrust plates 813 rotate toward each other to open, and their tops will move upward in the vertical direction during the rotation and opening process until their tops protrude above the working platform 81 to facilitate thrusting the battery 10.

[0049] A pressure sensor 1 811 and a pressure sensor 2 812 are respectively provided on the left and right sides of the top surface of the working platform 81 .

[0050] There is no retaining edge at the rear side of the bottom workbench 9, so as to facilitate cleaning of the debris dropped thereon during the cutting process.

[0051] In this embodiment, the opening and closing and working process of all power elements are controlled by the control unit EU, and each mechanism is connected and coordinated under the control of the control unit EU to complete the disassembly of the power battery shell.

[0052] The specific workflow is:

[0053] The battery 10 in the initial state is fed and conveyed via the inlet conveyor belt 2. The working platform 81 in the initial state is inclined toward the outlet conveyor belt 3 and the side close to the inlet conveyor belt 2 is in the same plane as the top surface of the inlet conveyor belt 2, which is conducive to the smooth introduction of the battery 10. When the battery 10 contacts the pressure sensor 811, the pressure sensor 811 detects the pressure and transmits the signal to the control unit EU. The control unit EU controls the screw motor 131 to start to drive the fork 4 to move to the right. Under the action of the fork 4, the angle of the battery 10 is adjusted. The fork 4 can also assist the battery 10 in being conveyed to the right. Afterwards, the battery 10 hits the pressure sensor on the thrust plate 813. When the pressure reaches the specified value, the control unit EU controls the screw motor 131 to reverse to drive the fork 4 to return to its original position.

[0054] Next, the control unit EU controls the push cylinder 822 to adjust the working platform 81 to a horizontal level, and energizes the solenoid valve to make the two thrust plates 813 close and retract towards each other. At the same time, the hydraulic cylinder 84 works to lift the working platform 81 upward to the working plane where the clamping mechanism 5 is located, and makes the two positioning push plates 513 close to the vertical cutting component 7 (i.e., the two positioning push plates 513 located at the rear and right sides of the device) extend to the predetermined positions and be fixed under the action of the corresponding push rod cylinders 512. After that, the other two push rod cylinders 512 are actuated to control the positioning push plates 513 at their inner ends to push inward until the positioning push plates 513 on the opposite side complete the four-direction extrusion positioning of the battery 10. At this time, the battery 10 reaches the cutting position and is in a compressed positioning state.

[0055] When the pressure sensor on the positioning push plate 513 on the two horizontal beams of the square frame connected to the top of the rack 1 senses that the pressure reaches a preset value, the signal is fed back to the control unit EU, that is, the positioning push plate 513 close to the side of the outlet conveyor belt 3 (that is, the positioning push plate 513 located on the right side of the device) is controlled to retract, and the positioning push plate 513 close to the side of the inlet conveyor belt 2 remains in place; the other two positioning push plates 513 maintain the pre-tightening force, and only the pressure generated by these two positioning push plates 513 is used to complete the clamping of the battery 10.

[0056] After the battery 10 is clamped, the vertical beam frame 72 moves along the bottom movable frame 71 toward the direction of the battery 10 under the action of the cylinder three 75. After reaching the preset position, the cylinder four 77 is started, so that the vertical cutting tool connecting part 73 moves downward under the action of the cylinder four 77 and ensures that the vertical cutting tool 74 rotates at a high speed. When the vibration sensor detects the vibration, it means that the vertical cutting tool 74 has contacted the battery. The control unit EU records the time t1 when the vertical cutting tool 74 starts working and the contact time t2 fed back by the vibration sensor. The height data of the battery 10 can be obtained through the time difference and the stroke rate data of the cylinder four 77. The control unit EU continues to control the vertical cutting tool 74 to cut downward. After the cutting is completed, the vertical cutting assembly 7 is reset.

[0057] Next, the horizontal cutting assembly 6 starts to be powered on and work. First, the moving beam 62 is lowered to the cutting height fed back by the control unit EU under the action of cylinder one 67. The horizontal cutting tool connector 63 starts to slide along the translation groove under the action of cylinder two 68 while ensuring that the horizontal cutting tool 64 is in a high-speed rotating cutting state. During the longitudinal movement, the longitudinal cutting of one side of the battery 10 is completed. After the cutting is completed, the horizontal cutting assembly 6 is reset.

[0058] Then, the four positioning push plates 513 are simultaneously retracted to the initial position, the rotary motor 83 is powered on, driving the working platform 81 and the battery 10 thereon to complete a 90° rotation, the clamping mechanism 5 repeats the above clamping and positioning operation, and the vertical cutting assembly 7 and the horizontal cutting assembly 6 perform cutting work again. This is repeated four times to complete the cutting of all the shells.

[0059] After the cutting is completed, the four positioning push plates 513 retract to the initial position at the same time, and the hydraulic cylinder 84 works to lower the working platform 81 and the battery 10 at the same time. The angle adjustment mechanism 82 adjusts the working platform 81 to tilt toward the export conveyor belt 3 and the side of the working platform 81 adjacent to the export conveyor belt 3 is in the same plane as the top surface of the export conveyor belt 3. After the battery 10 is pushed onto the export conveyor belt 3 by the fork 4, the pressure sensor 1 811 first feedbacks the pressure drop, and then the pressure sensor 2 812 also feedbacks the pressure drop. After receiving these two signals, the control unit EU records that the cutting work of a battery 10 has been completed, and all components in the device are reset to wait for the start of the next cutting cycle.

[0060] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
