Description

Technical Field

[0001] This utility model belongs to the field of waste lithium-ion battery recycling technology, specifically a waste battery shell breaking and dismantling device. Background Technology

[0002] With the development of new energy technologies, the use of lithium batteries has been increasing year by year. A large number of lithium batteries have been retired, and the market for recycling waste lithium-ion batteries has continued to grow. Existing waste lithium-ion battery recycling technologies mainly recycle and regenerate resources through two aspects: mechanical dismantling of scrapped batteries and metal extraction.

[0003] Existing lithium battery mechanical dismantling equipment generally adopts the method of directly crushing battery cells. On the one hand, during the crushing of lithium batteries, the electrolyte cannot be effectively recovered and is emitted into the atmosphere as organic waste gas, increasing environmental pressure. On the other hand, it is impossible to separate the positive electrode material, negative electrode material, and separator material, which leads to the following problems: First, the negative electrode material is mixed in with the powder and is often regarded as impurities, making it difficult to recycle. Second, the separated positive electrode powder often contains negative electrode material, has low purity, and cannot be directly recycled. Third, the separator material adheres to the battery fragments, and the separator filaments are easily entangled in subsequent crushing equipment, reducing the crushing efficiency and service life of the crushing equipment. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a waste battery shell breaking and dismantling device that can effectively separate the positive electrode, negative electrode and separator materials, and efficiently recover the electrolyte.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for breaking down and dismantling waste batteries includes a pretreatment module, an unwinding module, an electrolyte conditioning tank, and an induced draft fan;

[0007] The pretreatment module includes a closed chamber with a waste battery inlet on one side and a steel shell outlet on the other side.

A cell-pushing piston is also fixedly installed on the side wall of the chamber. The cell-pushing piston is connected to a third hydraulic control system fixedly installed outside the chamber.

[0008] The unwinding module includes a housing, inside which are a cell conveyor belt, a fixed rotating manipulator, and a layering and positioning manipulator. The rear end of the housing is open and rotatably connected to a positive electrode unwinding shaft, a diaphragm unwinding shaft, and a negative electrode unwinding shaft. The exterior of the housing is fixedly installed with first servo motors for driving the positive electrode unwinding shaft, the diaphragm unwinding shaft, and the negative electrode unwinding shaft. The rear end of the housing is also fixedly connected to a first chute, which has three channels corresponding to the positive electrode unwinding shaft, the diaphragm unwinding shaft, and the negative electrode unwinding shaft, respectively. The rear end of each channel has an outlet for the positive electrode, the diaphragm, or the negative electrode to slide out.

[0009] The compartment and the shell are provided with openings on opposite sides and are connected to each other through a second chute. A battery cell guide plate, which is opposite to the position of the battery cell pushing piston, is fixedly installed at the bottom of the second chute.

[0010] The top of the electrolyte regulating chamber is fixedly connected to an electrolyte extraction pipe, a lithium liquid replenishment pipe, and an organic solvent replenishment pipe. The electrolyte extraction pipe is connected to the outlet of the induced draft fan, and the inlet of the induced draft fan is connected to the top of the second chute.

[0011] Furthermore, the fixing clip includes a first fixing clip and a second fixing clip;

[0012] The first fixing clamp includes a base, which is slidably connected to a slide rail fixedly installed on the top surface of the silo body, and the base is fixedly connected to a nut of a ball screw fixedly installed on the top surface of the silo body. A first hydraulic rod is fixedly connected below the base, and a gripper is fixedly connected to the lower end of the first hydraulic rod.

[0013] The second fixing clamp includes a second hydraulic rod fixedly connected to the top surface of the compartment, and a clamping claw is fixedly connected to the lower end of the second hydraulic rod;

[0014] The outer side of the chamber is equipped with two first hydraulic control systems that are respectively connected to the first hydraulic rod and the second hydraulic rod.

[0015] Furthermore, the gripper includes a miniature dual-axis servo motor fixedly connected to the first hydraulic rod or the second hydraulic rod. Both output shafts of the servo motor are fixedly connected to screws, and the threads of the two screws are opposite in direction. The gripper body is threadedly connected to the screws.

[0016] Furthermore, the cutting mechanism includes a third hydraulic rod fixedly installed on both sides of the compartment, and a cutting blade for cutting the tabs of waste batteries is fixedly connected to the tail end of the third hydraulic rod.

[0017] A second hydraulic control system is fixedly installed on the outside of the silo body, and a third hydraulic rod is connected to the second hydraulic control system.

[0018] Furthermore, the fixed rotating manipulator is a six-axis ball joint manipulator, and the end effector of the manipulator is a tapered rotary dial that can be inserted into the center of the battery cell.

[0019] Furthermore, the layered positioning robot is a six-axis ball joint robot arm, and the end effector of the robot arm is a two-finger pneumatic gripper. Color detection sensors and position detection sensors are embedded on both sides of the two-finger pneumatic gripper, respectively.

[0020] Furthermore, the first chute is fixedly equipped with a positive electrode guide plate, a diaphragm guide plate, and a negative electrode guide plate that correspond one-to-one with the positive electrode unwinding shaft, the diaphragm unwinding shaft, and the negative electrode unwinding shaft. The positive electrode guide plate, the diaphragm guide plate, and the negative electrode guide plate divide the first chute into three channels.

[0021] The positive electrode guide plate has a positive electrode outlet at the end of the channel, the diaphragm guide plate has a diaphragm outlet at the end of the channel, and the negative electrode guide plate has a negative electrode outlet at the end of the channel.

[0022] Furthermore, a conductivity detector is fixedly installed in the electrolyte conditioning chamber, and the probe of the conductivity detector is set inside the electrolyte conditioning chamber to monitor the conductivity of the electrolyte and the interior of the electrolyte in real time.

[0023] Furthermore, the battery cell conveyor belt is a V-shaped guide groove structure conveyor belt.

[0024] Compared with the prior art, this utility model has the following technical effects:

[0025] This invention first uses a pre-processing module to remove the steel casing of waste lithium batteries. Then, through the rotation of the end effector of a fixed rotary manipulator, the stacked positive electrode, separator, and negative electrode are peeled off. Next, a layered repositioning manipulator identifies the positive electrode, separator, and negative electrode and places them into the corresponding positive electrode unwinding shaft, separator unwinding shaft, and negative electrode unwinding shaft. During rotation, the positive electrode, separator, and negative electrode unwinding shafts transport the positive electrode, separator, and negative electrode into the three channels of the first chute and discharge them from the outlets at the ends of the three channels. During this process, any escaped electrolyte is drawn into the electrolyte regulating chamber by the negative pressure of the induced draft fan and then replenished through the lithium electrolyte replenishment pipe. The system adds lithium liquid and a suitable solvent to the electrolyte conditioning chamber via an organic solvent replenishment tube, preparing the recovered electrolyte into a standard concentration. This not only reduces electrolyte volatilization and enables targeted discharge and efficient recycling of the electrolyte, thus lowering environmental treatment pressure, but also reduces electrolyte interference in subsequent powder recovery. In short, this invention integrates three major functions: battery casing breaking, separation of positive and negative electrode plates and separator, and electrolyte recovery. It achieves efficient recycling and regeneration of the electrolyte and effective separation of positive, negative, and separator materials. It is easy to combine with corresponding direct recycling methods for positive and negative electrodes for direct recycling of positive or negative electrode plates, improving the subsequent recycling rate and efficiency of positive and negative electrode plates.

[0026] This invention uses a first hydraulic control system to drive a ball screw and a first hydraulic rod to move the jaws of a first fixed clamp horizontally or vertically. An infrared distance sensor detects the position of the tabs on both sides of the used battery, allowing for precise gripping of the battery and movement between two cutting blades, facilitating the removal of the tabs from both ends. Simultaneously, a second hydraulic rod drives the jaws of a second fixed clamp to move vertically, accurately gripping the battery with the tabs removed and aligning the battery cell with the cell push piston for quick and easy ejection. This achieves effective separation of the steel casing and the battery cell, facilitating the recycling of the outer steel casing, reducing subsequent separation pressure, and increasing the purity of the battery powder.

[0027] This invention utilizes the vibration and rotation of the conical rotary needle of a fixed rotating manipulator to quickly separate stacked positive electrode sheets, separators, and negative electrode sheets. The layered positioning manipulator correctly identifies the positive electrode sheets, separators, and negative electrode sheets based on color signals uploaded by color detection sensors. According to position information uploaded by position detection sensors, the positive electrode sheets, separators, and negative electrode sheets are respectively fed into the positive electrode sheet unwinding shaft, separator unwinding shaft, and negative electrode sheet unwinding shaft. This achieves rapid and precise separation of the positive electrode sheets, separators, and negative electrode sheets, facilitating direct utilization of the positive and negative electrode sheets. It eliminates the need for secondary processing of the mixed positive and negative electrode powder and reduces the impact of the separator on subsequent pulverizing equipment, thus achieving cost reduction and efficiency improvement.

[0028] This invention uses a miniature dual-axis servo motor to drive two screws with opposite thread directions to rotate, thereby causing the two gripper bodies to move towards or away from each other, which facilitates efficient and rapid gripping of waste batteries of different sizes and improves gripping and release efficiency.

[0038] The specific content of this utility model will be further explained in detail below with reference to the embodiments.

[0039] like Figures 1 to 8 As shown, a waste battery shell breaking and dismantling device includes a pretreatment module 101, an unwinding module 102, and an electrolyte conditioning chamber 103.

[0040] like Figure 1 , Figure 3 and Figure 4As shown, the pretreatment module 101 includes a closed silo. One side of the silo has a waste battery inlet 113, which is an inclined chute to facilitate the entry of waste batteries into the silo under their weight. The other side of the silo has a downward-sloping steel shell outlet 105, which is also an inclined chute. A wear-resistant conveyor belt 118 is located at the bottom of the silo, employing an intermittent drive mode to intermittently transport the material. The inner top surface of the silo is connected to a first fixing clamp 122 and a second fixing clamp 123 for gripping waste batteries. The first fixing clamp 122 includes components fixedly mounted on the top surface of the silo. The base is slidably connected to the slide rail. The base is fixedly connected to the nut of the ball screw fixedly installed on the top surface of the hopper body. A first hydraulic rod is fixedly connected to the bottom of the base. A gripper is fixedly connected to the lower end of the first hydraulic rod. The ball screw drives the nut, thereby causing the base to move along the slide rail. The base drives the first hydraulic rod and the gripper to move. The second fixed clamp 123 includes a second hydraulic rod fixedly connected to the top surface of the hopper body. A gripper is fixedly connected to the lower end of the second hydraulic rod. The hopper body is provided with two first hydraulic control systems 116 that are respectively connected to the first hydraulic rod and the second hydraulic rod. The first hydraulic control systems 116 drive the first hydraulic rod and the second hydraulic rod, thereby causing the gripper to move up and down.

[0041] like Figure 7 As shown, the gripper includes a miniature dual-axis servo motor fixedly connected to the first hydraulic rod or the second hydraulic rod. Both output shafts of the servo motor are fixedly connected to screws 135, and the thread directions of the screws 135 connected to the two output shafts are opposite. The screws 135 are threadedly connected to the gripper body 136. When the servo motor rotates forward and backward, the two screws 135 drive the two gripper bodies 136 to move towards each other or away from each other, thereby gripping or releasing waste batteries of different sizes.

[0042] like Figure 3 and Figure 4As shown, a third hydraulic rod and an infrared distance sensor 134 are fixedly installed on both sides of the bin body. A cutting blade 119 for cutting waste batteries is fixedly connected to the tail end of the third hydraulic rod. The third hydraulic rod is connected to a second hydraulic control system 117 fixedly installed outside the bin body. When the infrared distance sensor 134 detects that the waste battery is fed between the two cutting blades 119 by the first fixing clamp 122, the second hydraulic control system 117 drives the third hydraulic rod, which in turn moves the cutting blade 119 to cut off the waste battery. The battery has tabs at both ends; the side wall is also equipped with a cell pushing piston 120, which is directly opposite the second fixing clamp 123. The cell pushing piston 120 is connected to a third hydraulic control system 121 fixedly installed outside the chamber. The third hydraulic control system 121 controls the cell pushing piston 120 to push the cell, so that the cell is released from the steel shell. The steel shell and the cell are separated. The steel shell is transported to the steel shell outlet 105 by the wear-resistant conveyor belt 118. Under the action of gravity, the steel shell slides out of the chamber from the steel shell outlet 105.

[0043] like Figure 1 , Figure 5 and Figure 6 As shown, the unwinding module 102 includes a housing, inside which are provided a cell conveyor belt 125, a fixed rotating manipulator 126, and a layering and positioning manipulator 127. The fixed rotating manipulator 126 and the layering and positioning manipulator 127 are located on both sides of the tail end of the cell conveyor belt 125. The tail end of the housing is open and rotatably connected to a positive electrode unwinding shaft 128, a diaphragm unwinding shaft 129, and a negative electrode unwinding shaft 130, respectively. Three first servo motors 108 are fixedly installed outside the housing to drive the positive electrode unwinding shaft 128, the diaphragm unwinding shaft 129, and the negative electrode unwinding shaft 130, respectively.

[0044] The fixed rotating manipulator 126 is a six-axis ball joint manipulator. The end effector of the manipulator is a conical rotary needle. The conical rotary needle is inserted into the center of the battery cell and rotates in a spiral motion to peel off the original stacked positive electrode, separator and negative electrode.

[0045] like Figure 5 and Figure 8As shown, the layered repositioning robot 127 is a six-axis ball joint robot arm. The end effector of the robot arm is a two-finger pneumatic gripper. Color detection sensor 137 and position detection sensor 138 are embedded on both sides of the two-finger pneumatic gripper. Since the positive electrode, diaphragm and negative electrode are different colors, the color detection sensor 137 is used to identify the colors. The controller of the layered repositioning robot 127 controls the two-finger pneumatic gripper to grasp the positive electrode, diaphragm and negative electrode respectively according to the signal uploaded by the color detection sensor 137. Then, the controller of the layered repositioning robot 127 puts the positive electrode, diaphragm and negative electrode into the positive electrode unwinding shaft 128, the diaphragm unwinding shaft 129 and the negative electrode unwinding shaft 130 respectively according to the information uploaded by the position detection sensor 138.

[0046] like Figure 2 and 5 As shown, the tail end of the housing is also fixedly connected to a first chute. Inside the first chute, a positive electrode guide plate 131, a diaphragm guide plate 132, and a negative electrode guide plate 133 are fixedly installed, corresponding one-to-one with the positive electrode unwinding shaft 128, the diaphragm unwinding shaft 129, and the negative electrode unwinding shaft 130, dividing the first chute into three channels. The tail end of the channel where the positive electrode guide plate 131 is located is provided with a positive electrode outlet 107, and the tail ends of the channels where the diaphragm guide plate 132 and the negative electrode guide plate 133 are respectively provided with a diaphragm outlet 114 and a negative electrode outlet 115.

[0047] The hopper and the shell are provided with openings on opposite sides and are connected to each other through a second chute. A cell guide plate 124 is fixedly installed at the bottom of the second chute. The cell guide plate 124 is directly opposite the cell push piston 120, so that the cell push piston 120 can push the cell directly onto the cell guide plate 124. The cell guide plate 124 is inclined so that the cell can slide along the cell guide plate 124 to the cell conveyor belt 125 under the action of gravity. The cell conveyor belt 125 adopts a V-shaped guide groove belt structure, which facilitates the transport of the cell to the vicinity of the fixed rotating manipulator 126.

[0048] like Figure 1As shown, the top of the second chute is open and connected to the air inlet of the blower 104. The air outlet of the blower 104 is connected to an electrolyte extraction pipe 106. The electrolyte extraction pipe 106 is connected to the top of the electrolyte regulating chamber 103. The top of the electrolyte regulating chamber 103 is also connected to a lithium liquid replenishment pipe 110 and an organic solvent replenishment pipe 111. The lower side of the electrolyte regulating chamber 103 is connected to an electrolyte outlet pipe 112. A conductivity detector 109 is fixedly installed in the electrolyte regulating chamber 103. The probes of the conductivity detector 109 are all located inside the electrolyte regulating chamber 103 for real-time monitoring of the conductivity inside the electrolyte regulating chamber 103. The display screen of the conductivity detector 109 is located outside the electrolyte regulating chamber 103 for displaying the conductivity.

[0049] The negative pressure generated by the induced draft fan 104 draws the gaseous electrolyte into the electrolyte conditioning chamber 103 through the electrolyte extraction pipe 106. A composite solvent is added to the electrolyte conditioning chamber 103 through the organic solvent replenishment pipe 111, and lithium liquid is added to the electrolyte conditioning chamber 103 through the lithium liquid replenishment pipe 110. During this process, the lithium content in the electrolyte is detected by the conductivity detector 109, and the liquid inflow of the lithium liquid replenishment pipe 110 and the organic solvent replenishment pipe 111 is dynamically adjusted to ensure that the LiPF6 concentration in the electrolyte conditioning chamber 103 is maintained at 0.5-1.5 mol / L. The prepared standard concentration electrolyte is discharged from the electrolyte outlet pipe 112 and used for the production of lithium batteries.

[0050] Preferably, the composite solvent added to the electrolyte conditioning chamber 103 is a mixture of various carbonate solvents, which can promote the effective dissolution and stabilization of each component in the lithium-ion battery electrolyte. Specifically, the composite solvent is a mixture of ethylene carbonate (EC), dimethyl carbonate (DMC), and ethyl methyl carbonate (EMC) in a volume ratio of 1:1:1, which not only has good solubility but also stable electrochemical properties. The composite solvent is a mixture of dimethyl carbonate (DMC) and ethylene carbonate (EC) in a volume ratio of 1:1. In order to adapt to different application requirements and performance indicators, specific carbonate solvents can be selected and the proportions adjusted according to the specific requirements of battery design and operating conditions.

[0051] The working principle of this utility model is as follows:

[0052] Waste batteries are fed into the waste battery inlet 113. Under gravity, the waste batteries fall from the waste battery inlet 113 into the chamber of the pretreatment module 101. They are picked up by the first fixing clamp 122 and sent between the two cutting blades 119. When the infrared distance sensor 134 detects that the tabs at both ends of the waste battery are directly below the cutting blades 119, the tabs at both ends of the waste battery are cut off by the cutting blades 119. The first fixing clamp 122 releases the waste battery with the tabs cut off. When the wear-resistant conveyor belt 118 transports the waste battery with the tabs cut off to the area below the second fixing clamp 123, the second fixing clamp 123 clamps the waste battery with the tabs cut off. The battery cell pushes the piston 120 to push out the battery cell, separating the battery cell from the steel shell. The battery cell is pushed to the battery cell guide plate 124. The second fixing clamp 123 releases the steel shell. The steel shell is transported by the wear-resistant conveyor belt 118 to the steel shell outlet 105. Under gravity, the steel shell... The battery cell slides out from inside the housing; the battery cell enters the housing of the unwinding module 102 along the battery cell guide plate 124, and is transported by the battery cell conveyor belt 125 to the bottom of the fixed rotating robot 126. The conical rotary needle of the fixed rotating robot 126 inserts into the center of the battery cell, and the spiral vibration and rotation cause the originally stacked positive electrode, separator and negative electrode to be peeled off. The layered positioning robot 127 identifies the positive electrode, separator and negative electrode through the color detection sensor 137, and according to the position signal uploaded by the position detection sensor 138, puts the positive electrode, separator and negative electrode into the unwinding shaft 128, separator unwinding shaft 129 and negative electrode unwinding shaft 130 respectively. The positive electrode slides down along the positive electrode guide plate 131 and is discharged from the positive electrode outlet 107. The negative electrode slides along the negative electrode guide plate 133 and is discharged from the negative electrode outlet 115. The separator slides along the separator guide plate 132 and is discharged from the separator outlet 114.

[0053] Lithium and composite solvent are added to the electrolyte conditioning chamber 103 through the lithium liquid replenishment tube 110 and the organic solvent replenishment tube 111 to adjust the lithium content in the electrolyte. The lithium content in the electrolyte is monitored by the conductivity detector 109, and the liquid inflow of the lithium liquid replenishment tube 110 and the organic solvent replenishment tube 111 is dynamically adjusted to control the LiPF6 concentration at 0.5-1.5 mol / L. The electrolyte within the standard concentration range is discharged through the electrolyte outlet tube 112 for use in assembling new batteries.
