Description

Technical Field

[0001] This invention relates to the field of waste material recycling and processing technology, and in particular to an automatic dismantling device for utilizing residual energy in waste batteries. Background Technology

[0002] Household batteries contain large amounts of heavy metals and electrolyte solutions such as waste acids and alkalis, which can cause serious pollution to the natural environment if not properly disposed of. However, many substances in waste batteries can be recycled. Efficient and energy-saving battery recycling and dismantling technologies can not only avoid environmental pollution but also reduce energy and resource consumption during the recycling process. Currently, domestic and international battery recycling and dismantling systems generally fall into two categories. One type uses mechanical devices to first crush the entire waste lead-acid battery and then uses various technical measures to separate the mixed substances. However, this often results in some finely fragmented lead-containing materials and plastic materials adhering to each other, making separation difficult and easily causing secondary pollution during recycling. Furthermore, the residual energy within the old battery is wasted during the crushing process, which contradicts the principles of energy conservation and environmental protection. Summary of the Invention

[0003] To address the aforementioned shortcomings, this invention provides an automatic dismantling device for the residual energy utilization of waste batteries. This device can recycle and reuse the residual electricity in waste batteries and automatically complete tasks such as cutting the top and bottom covers of the battery, pushing out the electrode plates, and breaking and cutting the battery casing. It is suitable for use in assembly line operations.

[0004] An automatic dismantling device for utilizing residual energy in waste batteries includes: a discharge unit, a connection unit, and a dismantling unit; the discharge unit and the dismantling unit are arranged on both sides of the connection unit. The discharge unit is used to place the waste batteries to be dismantled in a fixed position and collect the residual energy in the batteries, thereby using the residual electricity in the waste batteries to power power equipment; the connection unit transfers the discharged batteries from the discharge unit to the dismantling unit; the dismantling unit is used to cut off the upper and lower covers of the battery, push out the electrode plates inside the battery, and dismantle the battery casing.

[0005] Preferably, the discharge unit includes a discharge rack, a battery placement box, a three-axis trolley, and a conveyor belt. The discharge rack is constructed from profiles and is arranged in a multi-row, multi-column grid pattern. Each grid can hold one battery placement box. At the bottom left and right of each grid, there is an electrode plate that is insulated from the discharge rack. The electrode plates are electrically connected to the terminals at the bottom of the battery placement box. A slide rail is installed on the outer edge of the top of the discharge rack, and the three-axis trolley can move left and right along the slide rail.

[0006] Preferably, the battery placement box includes a box body, a frame, and a base plate. The box body is designed to fit the size of the battery. The bottom of the base plate is provided with terminals, which correspond to the terminals of the battery pack inside the box. When the battery placement box is placed on the discharge rack, the terminals under the bottom plate of the battery placement box abut against the plates on the discharge rack, thereby drawing out and storing the current from the battery pack to power the motors at each workstation.

[0007] Preferably, the three-axis trolley includes a transverse frame, a transverse slider, a transverse motor, a lifting frame, a lifting slider, a lifting motor, lifting guide wheels, a lifting cable, a lifting guide rail, a fork arm, a fork arm slider, a fork arm push rod, and a push rod column. A transverse slider is mounted on the upper part of the transverse frame, and the transverse slider can slide along a slide rail fixed on the discharge frame. The transverse motor drives the transverse frame to move left and right along the discharge frame via a chain. Lifting guide rails are mounted on the left and right sides of the transverse frame for the lifting frame to move up and down. Correspondingly, a lifting slider is mounted on the lifting frame, and the lifting slider can slide up and down along the lifting guide rail on the transverse frame. The fork arm and fork arm push rod are mounted on the lifting frame, and a fork arm slider is installed between the fork arm and the lifting frame. The fork arm push rod can drive the fork arm to extend and retract, thereby coordinating with the movement of the lifting frame. The forklifts allow battery holders to be placed on or removed from the discharge rack. During this process, the horizontal frame first aligns with a column of battery holders on the discharge rack, then the vertical frame aligns with a row within that column. The forklifts then extend from below the left and right edges of the battery holders into the discharge rack. The vertical frame then lifts the battery holders a short distance, the forklifts retract to remove the used batteries, and the vertical frame lowers to place the battery holders onto the conveyor belt below. After the forklifts retract a further distance and detach from the battery holders, the conveyor belt... The system initiates the process of delivering the removed used batteries to the receiving unit. Simultaneously, the conveyor belt transports the battery placement box containing the batteries to be discharged to the area directly below the lifting frame. Forks extend from under the left and right sides of the battery box, and the lifting frame lifts the battery placement box to an empty space on the discharge rack. After the forks extend and deliver the battery placement box into position, the lifting frame moves downward a short distance to place the battery placement box on the discharge rack. Then, the forks retract, and after the battery placement box is placed on the discharge rack, the electrode posts on the bottom of the battery placement box fall onto the electrode plates of the discharge rack, using gravity to maintain close contact between the electrode posts and the electrode plates.

[0008] Preferably, the conveyor belt is located in front of the discharge rack and is placed parallel to the discharge rack, used to deliver the battery placement box to the position of the three-axis trolley, or to deliver the discharged battery placement box to the position of the connecting unit.

[0009] Preferably, the connecting unit includes a flipping frame, a flipping motor, slot hooks, a flipping frame chain, a flipping receiving platform, a flipping push rod, and a flipping receiving platform shaft. The flipping frame is located at one end of the conveyor belt. The flipping receiving platform is movably connected to the flipping frame via the flipping receiving platform shaft. A flipping push rod is provided below the flipping receiving platform. The flipping motor is drive-connected to the flipping frame via the flipping frame chain. Upper and lower slot hooks are provided at the front of the flipping frame. When the flipping motor drives the flipping frame to flip, the lower edge of the slot hook can just hook onto the front and rear edges of the battery placement box.

[0010] Preferably, the disassembly unit includes a flip-top receiving platform, a receiving platform push rod, a transverse feeding push rod, a longitudinal feeding push rod, a cutter, a lead pusher, a shell-breaking machine, and a battery holder. The flip-top receiving platform remains perpendicular to the flipping frame during receiving, ensuring that batteries sliding off the flipping frame can continue to slide along the receiving platform surface. When the battery slides into position, the receiving platform push rod pushes the flip-top receiving platform surface to a horizontal state. The transverse feeding push rod is installed on the flip-top receiving platform and can reciprocate in a direction perpendicular to the direction in which the battery slides, thereby pushing the batteries one by one onto the feeding platform in front of the cutter. The longitudinal feeding push rod is installed on the feeding platform, and its direction of movement is orthogonal to the transverse feeding push rod, pushing one battery into the cutting machine's feed inlet each time.

[0011] Preferably, the cutting machine includes a cutting table, a fixed blade, a moving blade, a moving blade holder, a cutting guide column, a cutting screw, a cutting screw seat, a cutting motor, and a cutting guide column. The cutting table is in contact with the feeding table. The fixed blade has two blades with their blade surfaces vertically mounted on the cutting table. The moving blade is mounted on the moving blade holder, which can slide along the cutting guide column. A nut that mates with the cutting screw is installed on the moving blade holder. The cutting screw seat is mounted on the cutting table to support the screw. When the cutting motor drives the screw to rotate, the nut on the moving blade holder drives the moving blade holder to move along the cutting guide column. The waste battery is pushed between the cutting edges of the moving blade and the fixed blade. The moving blade holder pushes the battery towards the fixed blade, and the alternation of the fixed blade and the moving blade removes the upper and lower covers of the battery.

[0012] Preferably, the lead pusher includes lead pusher claws, lead pusher claw support frame, lead pusher guide column, lead pusher screw, and lead pusher motor. There are six lead pusher claws mounted on the lead pusher claw support frame. The lead pusher claw support frame can slide back and forth along the lead pusher guide column. A nut is installed on the lead pusher claw support frame. The lead pusher screw cooperates with the nut. The lead pusher motor drives the lead pusher screw to rotate. The nut drives the lead pusher claws to move linearly along the lead pusher guide column. The reciprocating motion of the lead pusher claws is achieved by the forward and reverse rotation of the lead pusher motor, pushing out the electrode plate in the battery directly in front.

[0013] Preferably, the shell-breaking machine includes a shell-breaking claw, a shell-breaking guide post, a shell-breaking screw, and a shell-breaking motor. The shell-breaking claw can slide back and forth along the shell-breaking guide post. The shell-breaking claw is equipped with a nut. The shell-breaking screw cooperates with the nut on the shell-breaking claw. The shell-breaking motor drives the shell-breaking screw to rotate, and through the nut on the shell-breaking claw, it drives the shell-breaking claw to move linearly along the shell-breaking guide post. When the shell-breaking motor rotates forward and backward, the shell-breaking claw reciprocates accordingly.

[0014] Its beneficial effects are as follows: The automatic dismantling device for the utilization of residual energy in waste batteries of this invention can automatically perform the processes of residual energy recovery, battery cutting, and casing dismantling. The device has a simple, compact, and reliable structure. In the residual energy recovery stage, the residual energy in the battery is drawn out through the electrode posts on the bottom plate of the battery placement box and the electrode plates on the discharge rack. The battery's own weight is used to press the battery against the electrode posts of the battery placement box, ensuring reliable contact. In the cutting stage, a fixed cutter is used while the battery moves, which reduces the requirements for the rigidity and motion precision of moving and heavy-duty components and increases the cutting speed. In the electrode plate ejection device, to improve the alignment accuracy between the pusher claws and the battery electrode plate compartment, a battery compartment gap is left between two adjacent pusher claws. The electrode plates in each battery are ejected in two stages. Each pusher claw movement ejects the electrode plates from two batteries. That is, as the battery is fed in, the electrodes in each battery are ejected sequentially. This process effectively solves the problem of difficult battery casing positioning when ejecting the electrode plates. Simultaneously, the residual energy in the battery is recovered and utilized, avoiding energy waste. Attached Figure Description

[0018] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0019] like Figure 1As shown, an automatic dismantling device for the utilization of residual energy in waste batteries includes: a discharge rack 100, a three-axis trolley 110, a battery placement box 140, a conveyor belt 130, a tilting rack 150, a tilting receiving platform 200, a transverse feeding pusher 210, a longitudinal feeding pusher 220, a cutter 240, a lead pusher 260, and a shell-breaking machine 280. The three-axis trolley 110 is mounted on the discharge rack 100, and the battery placement box 140 is placed on the discharge rack 100. The conveyor belt 130 is positioned close to the discharge rack 100. After the waste batteries in the battery placement box 140 are discharged by the discharge rack 100, they are conveyed to the next process by the conveyor belt 130. A flipping frame 150 and a flipping receiving platform 200 are provided next to the conveyor belt 130. The batteries that enter the flipping receiving platform 200 are pushed into the cutting machine 240 by the horizontal feeding push rod 210 and the vertical feeding push rod 220 to cut off the battery cover. Finally, the lead pusher 260 and the shell breaking machine 280 are used to push the lead and break the shell of the battery.

[0020] Figure 2 The diagram shows the structure of the discharge rack 100 in this invention. Two three-axis trolley transverse guide rails 103 and 104 are mounted on the discharge rack 100. A transverse motor 105 and a sprocket 107 are mounted on the top of the discharge rack. The transverse motor drives the three-axis trolley 110 to slide along transverse guide rails A103 and B104 via a chain 106. Transverse guide rails A and B are arranged parallel to each other. Each cell of the discharge rack 100 is equipped with lead-out electrode plates 101 and 102, which are insulated from the discharge rack 100. These plates are connected to the terminals of the batteries inside the battery storage box via the lower terminal post 144 at the bottom of the battery storage box 140, thereby extracting, storing, and using the residual electrical energy from the waste batteries.

[0021] like Figure 3As shown, the three-axis trolley 110 consists of a transverse frame 111, transverse sliders 112, a transverse motor 105, a lifting frame 113, lifting sliders 114, a lifting motor 119, lifting guide wheels 120, a lifting cable 121, a lifting guide rail 122, forks 115, fork sliders 116, fork push rods 117, and push rod columns 118. The four sliders 112 mounted on the transverse frame 111 slide along the transverse guide rails A103 and B104 fixed to the discharge frame, respectively. The transverse motor 105 drives the transverse frame 111 to move left and right via a chain 106. Lifting guide rails 122 are mounted on the left and right sides of the transverse frame 111. Four lifting sliders 114 mounted on the lifting frame 113 can slide up and down along the lifting guide rails 122. Two fork sliders 116 are fixed to the left and right sides of the lifting frame 113, respectively. On the right two side frames, when the fork arm push rod 117 extends and retracts, the push rod column 118 fixed on the fork arm 115 drives the fork arm 115 to extend and retract into the discharge rack 100, thereby facilitating the picking and placing of the battery placement box 140. When picking and placing the battery placement box, the horizontal frame 111 first aligns with a column of battery placement boxes on the discharge rack 100, and then the lifting frame 113 aligns with a row of battery placement boxes in that column. Then, the fork arm 115 extends into the discharge rack from below the left and right side frames of the battery placement box 140. Next, the lifting frame 113 lifts the battery placement box a certain distance upwards, the fork arm 115 retracts to remove the battery box, and the lifting frame 113 descends to place the battery placement box on the conveyor belt 130 below. After the fork arm 115 retracts a certain distance to detach from the battery placement box 140, the conveyor belt 130 starts to send the battery placement box 140 to the connection unit. Simultaneously, the conveyor belt 130 delivers another battery placement box 140, containing batteries to be discharged, directly below the lifting frame. Fork arms 115 extend from under the left and right sides of the battery box, and the lifting frame 113 lifts the battery placement box to an empty space on the discharge rack 100. After the fork arms 115 extend and deliver the battery placement box to a fixed position, the lifting frame 113 moves downwards a short distance, placing the battery placement box on the discharge rack, and then the fork arms 115 retract. After the battery placement box 140 is placed on the discharge rack, the electrode posts on the bottom surface of the battery placement box 140 rest on the electrode plates of the discharge rack, using gravity to maintain close contact between the electrode posts and the lead-out electrode plates A and B.

[0022] like Figure 4 As shown, the battery placement box 140 in this embodiment consists of a box body 141, a frame 142, and a base plate 145 with terminals. The upper terminals 143 on the upper side of the base plate 145 with terminals are in contact with the terminals of the battery pack inside the box. When the battery placement box 140 is placed on the discharge rack 100, the lower terminals 144 on the lower side of the base plate 145 are in contact with the lead-out electrode plates A and B on the discharge rack 100, thereby drawing out the current of the battery pack to power the motors at each station.

[0023] like Figure 5As shown, the connecting unit in this embodiment consists of a tilting frame 150, a tilting motor 151, a slot hook 152, a tilting frame chain 153, a tilting receiving platform 200, a tilting push rod 154, and a tilting receiving platform rotating shaft 201. The tilting frame 150 is located at one end of the conveyor belt. The tilting receiving platform 200 is movably connected to the tilting frame 150 through the tilting receiving platform rotating shaft 201. A tilting push rod 154 is provided below the tilting receiving platform 200. The tilting motor 151 is connected to the tilting frame 150 in a transmission manner through the tilting frame chain 153. A slot hook 152 is provided at the front end of the tilting frame 150. When the flipping motor 151 drives the flipping frame 150 to flip, the lower edge of the slot hook 152 can just hook onto the front and rear edges of the battery placement box 140, thereby lifting the battery placement box 140. After the battery placement box 140 flips with the flipping frame at an angle greater than 90 degrees and less than 180 degrees, the battery slides from the battery placement box 140 onto the flipping receiving platform 200. The battery placement box 140 is held on the flipping frame by the aforementioned slot hook 152. After the battery is removed, the flipping frame 150 rotates back to its initial position and places the battery placement box 140 on the conveyor belt 130. The conveyor belt 130 then moves the battery placement box 140 out of the slot hook 152.

[0024] like Figure 6 As shown, the cutting machine in this embodiment includes a cutting table 223, a fixed blade 224, a movable blade 225, a movable blade holder 226, a cutting guide post 227, a cutting lead screw 228, a cutting lead screw seat 231, and a cutting motor 229. There are two fixed blades 224 and two movable blades 225. The movable blade 225 is mounted on the movable blade holder 226 and can slide along the cutting guide post 227 with the blade holder. A nut that cooperates with the cutting lead screw 228 is installed on the rear push plate 230 of the movable blade holder. When the cutting motor 229 drives the cutting lead screw 228 to rotate, the nut on the rear push plate 230 drives the movable blade holder 226 to move along the cutting guide post 227, thereby using the alternation of the fixed blade 224 and the movable blade 225 to cut off the upper and lower covers of the battery.

[0025] like Figure 7 As shown, the lead pusher of this embodiment includes lead pusher claws 261, lead pusher claw support frame 262, lead pusher guide column 263, lead pusher screw 264, and lead pusher motor 265. There are six lead pusher claws 261 mounted on the lead pusher claw support frame 262. The lead pusher claw support frame 262 can slide back and forth along the lead pusher guide column 263. A nut is installed on the lead pusher claw support frame 262. The lead pusher screw 264 cooperates with the nut. The lead pusher motor 265 drives the lead pusher screw 264 to rotate, and then drives the lead pusher claws 261 to move linearly along the lead pusher guide column through the nut.

[0026] In this embodiment, the shell-breaking machine 280 includes a shell-breaking claw 281, a shell-breaking guide post 282, a shell-breaking screw 283, and a shell-breaking motor 284. The shell-breaking claw 281 can slide back and forth along the shell-breaking guide post 282. The shell-breaking claw 281 is equipped with a nut. The shell-breaking screw 283 cooperates with the nut on the shell-breaking claw 281. The shell-breaking motor 284 drives the shell-breaking screw 283 to rotate. Through the nut on the shell-breaking claw, the shell-breaking claw 281 moves linearly along the shell-breaking guide post 282. When the shell-breaking motor 284 rotates forward and backward, the shell-breaking claw reciprocates accordingly.

[0027] In practical use, the battery placement box 140 containing several batteries to be disassembled is first placed on the conveyor belt 130. Then, the three-axis trolley 110 stacks the battery placement box 140 into the empty space of the discharge rack 100. The batteries in the battery placement box 140 are all placed with their electrodes facing down, and the batteries are of the same size and model. The electrode post of each battery is in contact with the upper electrode post 127 on the base plate 129. Multiple sets of upper electrode posts 127 are connected in parallel and connected to the lower electrode post 128 on the outside of the base plate 129. When the battery placement box 140 is stacked on the discharge rack, the lower electrode post 128 on the outside of its base plate 129 connects with the lead-out electrodes 101 and 102 on the discharge rack. The battery can be recharged and reused by recycling the remaining charge in the battery. After the waste battery is discharged, the three-axis trolley 110 takes out the battery placement box 140 and puts it on the conveyor belt 130, and then transfers it to the flipping frame 150 of the receiving unit. The flipping frame 150 is flipped by the flipping motor 151, which flips the battery upside down onto the flipping receiving table 200. The battery is first pushed to the cutting table by the horizontal feeding push rod 210, and then pushed into the cutting machine 240 by the vertical feeding push rod 220. After the top and bottom covers are cut off, the lead-containing plates in the battery compartment are pushed out by the lead pusher 260, and then the battery casing is broken open by the shell-breaking machine 280.

[0028] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

The flip-top receiving platform maintains the same tilt angle as the flipping frame during receiving, ensuring that batteries sliding off the flipping frame can continue to slide along the receiving platform surface. Once the battery has slid into position, the receiving platform push rod pushes the platform surface to a horizontal state. The horizontal feeding push rod, mounted on the flip-top receiving platform, can reciprocate in a direction perpendicular to the direction the battery slides off, thus pushing the batteries one by one onto the feeding platform in front of the cutter. The vertical feeding push rod, mounted on the feeding platform, moves in a direction orthogonal to the horizontal feeding push rod, pushing one battery at a time into the cutting machine's feed inlet.

6. The automatic dismantling device for utilizing residual energy in waste batteries according to claim 5, characterized in that: The cutting machine includes a cutting table, a fixed blade, a moving blade, a moving blade holder, a cutting guide column, a cutting screw, a cutting screw seat, a cutting motor, and a cutting guide column. The cutting table is connected to the feeding table. The fixed blade has two blades, with the blade surfaces vertically mounted on the cutting table. The moving blade is mounted on the moving blade holder, which can slide along the cutting guide column. A nut that mates with the cutting screw is installed on the moving blade holder. The cutting screw seat is mounted on the cutting table to support the screw. When the cutting motor drives the screw to rotate, the nut on the moving blade holder drives the moving blade holder to move along the cutting guide column. The waste battery is pushed between the cutting edges of the moving blade and the fixed blade. The moving blade holder pushes the battery towards the fixed blade, and the alternation of the fixed blade and the moving blade removes the top and bottom covers of the battery.

7. The automatic dismantling device for utilizing residual energy in waste batteries according to claim 5, characterized in that: The lead pusher includes lead pusher claws, lead pusher claw support frame, lead pusher guide column, lead pusher screw, and lead pusher motor. There are six lead pusher claws mounted on the lead pusher claw support frame. The lead pusher claw support frame can slide back and forth along the lead pusher guide column. A nut is installed on the lead pusher claw support frame. The lead pusher screw cooperates with the nut. The lead pusher motor drives the lead pusher screw to rotate, and through the nut, drives the lead pusher claws to move linearly along the lead pusher guide column. The reciprocating motion of the lead pusher claws is achieved by the forward and reverse rotation of the lead pusher motor, pushing out the electrode plate in the battery directly in front.

8. The automatic dismantling device for utilizing residual energy in waste batteries according to claim 5, characterized in that: The shell-breaking machine includes a shell-breaking claw, a shell-breaking guide post, a shell-breaking screw, and a shell-breaking motor. The shell-breaking claw can slide back and forth along the shell-breaking guide post. The shell-breaking claw is equipped with a nut. The shell-breaking screw cooperates with the nut on the shell-breaking claw. The shell-breaking motor drives the shell-breaking screw to rotate, and through the nut on the shell-breaking claw, it drives the shell-breaking claw to move linearly along the shell-breaking guide post. When the shell-breaking motor rotates forward and backward, the shell-breaking claw will reciprocate accordingly.
