Description

Technical Field

[0001] This invention relates to a battery recycling device, and more particularly to a waste battery recycling and discharge device. Background Technology

[0002] Lithium batteries, as the main carrier of new energy, are composed of copper and aluminum foil, nickel, cobalt, lithium manganese salt, graphite, electrolyte, separator paper, etc. During the recycling process of lithium batteries, if the charged battery is squeezed or punctured during recycling, it may trigger this reaction, causing a fire or explosion. Therefore, the battery needs to be discharged before recycling. Most existing methods use resistive loads or special discharge equipment to slowly release residual electrical energy.

[0003] Traditional devices often use low current to discharge batteries for safety reasons. While this ensures safe discharge, the discharge efficiency is very low because two hours have passed after the battery is fully discharged. Therefore, current methods use high current for discharge, which is much faster. However, discharging at high power causes the battery temperature to rise rapidly, making it prone to overheating, fire, spontaneous combustion, or explosion, resulting in very poor safety.

[0004] Therefore, this case aims to provide a waste battery recycling and discharge equipment, which can not only use a robotic arm to load batteries of known specifications into the corresponding three-dimensional bins, but also ensure that the batteries are discharged with the most suitable current in the corresponding three-dimensional bins. The discharge speed is extremely fast, and the temperature is monitored throughout the process to ensure the safe discharge. Summary of the Invention

[0005] This invention provides a recycling and discharging device for waste batteries, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows: A waste battery recycling and discharging device includes: a measuring platform for measuring battery dimensions, a milling section discharge conveyor belt disposed on the side of the measuring platform near the discharge point, and several three-dimensional storage cabinets disposed on both sides of the milling section discharge conveyor belt; and further includes: An adaptive distribution and adjustment structure includes a discharge robot mounting platform set on the discharge conveyor belt of the milling section. A loading and unloading robot is mounted on the discharge robot mounting platform. The loading and unloading robot clamps the batteries conveyed from the discharge conveyor belt of the milling section into the cabinet of an empty three-dimensional warehouse cabinet, and removes the discharged batteries and moves them to the discharge conveyor belt of the milling section. The discharge device includes several battery discharge racks mounted on an automated storage cabinet. Each battery discharge rack has two discharge modules, and each discharge module has a copper plate fixed to it. The copper plate is connected to the discharge cabinet via a terminal block. Each discharge module has a heat dissipation structure and a discharge limiting structure facing upwards. The battery discharge racks have a dual-channel temperature detection structure. When a robotic arm loads a battery onto the battery discharge rack, the discharge limiting structure pushes the battery onto the discharge module, causing the battery terminals to contact the copper plate and energize the terminal block to discharge the battery. The current distribution structure includes several discharge cabinets installed inside the automated storage and retrieval system. All the discharge cabinets are connected to the same terminal. The number of discharge cabinets corresponds one-to-one with the number and position of the battery discharge racks. The encoder of the measuring platform is electrically connected to the loading and unloading robot, and the loading and unloading robot is electrically connected to the discharge cabinets. When the loading and unloading robot transfers the measured battery to the corresponding battery discharge rack, the discharge cabinet corresponding to the battery discharge rack outputs a current of the corresponding magnitude according to the size of the battery.

[0007] As a further improvement, a dual-station mounting plate is provided on the output end of the loading and unloading robot, and two transfer stations are provided at the lower end of the dual-station mounting plate, with a bidirectional clamping motor assembly installed in each transfer station.

[0008] As a further improvement, the discharge module includes a module mounting base locked onto a battery discharge mounting frame, wherein a hollow aluminum base is locked onto the module mounting base, and the copper sheet is locked onto the aluminum base.

[0009] As a further improvement, the heat dissipation structure includes several heat dissipation fins and an external fan. The heat dissipation fins are arranged on four sides inside the aluminum base, and the external fan is arranged on the axial direction of one of the aluminum bases. The heat generated when the battery discharges is dissipated through the heat dissipation fins to the inner wall of the aluminum base and blown away by the external fan.

[0010] As a further improvement, the ends of the heat dissipation fins on the same side are formed into an arc-shaped surface.

[0011] As a further improvement, the module mounting base includes a module mounting plate for locking the aluminum material base, and a U-shaped plate is integrally formed between the two module mounting plates. The dual-channel temperature detection structure is set on the projection line of the opening of the U-shaped plate.

[0012] As a further improvement, the dual-channel temperature detection structure includes a first temperature sensor disposed on one side of the U-shaped plate, and a second temperature sensor disposed opposite the first temperature sensor.

[0013] As a further improvement, the battery discharge mounting bracket is provided with a clearance groove, and the discharge limiting structure includes a discharge push rod motor disposed inside the battery discharge mounting bracket. A heightening plate that penetrates the clearance groove is connected to the baffle at the end of the discharge push rod motor. The width of the heightening plate is smaller than the width of the clearance groove, and a lever plate is connected to the upper end of the heightening plate.

[0014] As a further improvement, a limit stake is provided on the side of the dial away from the discharge module.

[0015] As a further improvement, a guide post is provided on the baffle at the end of the discharge push rod motor. The guide post is sleeved on a discharge guide rod, which is fixed to both ends inside the battery discharge mounting frame.

[0016] The beneficial effects of this invention are: Existing technologies utilize some automated storage and retrieval systems (AS / RS) for battery storage. However, the layout of the entire warehouse is narrow, the loading and unloading routes are complex, and the loading and unloading stages need to be completely separated. Furthermore, the small spacing between the compartments can easily affect the surrounding batteries. Therefore, this invention first adopts an adaptive distribution and adjustment structure, using robotic arms to replace manual loading and unloading, thereby avoiding the potential dangers of manual loading. The AS / RS cabinets are positioned at both ends, with the robotic arms positioned in the center, allowing them to reach each compartment of the AS / RS cabinets. During the loading intervals, the discharged batteries are removed, thus forming a virtuous cycle.

[0017] Because batteries have different specifications and different charge contents, discharging batteries of different specifications with the same current will either result in incomplete discharge or excessive temperature. Therefore, this invention uses a current distribution structure to set up multiple discharge cabinets in an automated storage cabinet, thereby achieving different current outputs on different battery discharge racks. First, the battery specifications are measured by a measuring table at the front end. Then, a loading and unloading robot clamps the battery onto any battery discharge rack. The discharge cabinet in the battery discharge rack is connected to the battery size information obtained by the loading and unloading robot, and the specifications are compared with the specifications pre-stored in the database. This outputs the optimal current corresponding to the battery size, allowing the battery to achieve the best discharge effect, discharging completely and very quickly.

[0018] Existing technologies directly use high current for discharge, resulting in very fast discharge speeds. However, under high power conditions, the battery temperature rises rapidly, easily leading to overheating, fire, spontaneous combustion, or explosion, posing a significant safety risk. Therefore, this invention addresses this by directly integrating a heat dissipation structure onto the discharge module and using a discharge limiting structure to push the battery into contact with the discharge module. This allows for timely heat dissipation into the discharge module and rapid discharge through it, enabling quick heat removal even at slightly higher currents and preventing battery overheating and fire.

[0019] To improve the heat dissipation of the discharge module and avoid the disadvantages of its solid structure, this invention makes the location where the copper plate of the discharge module is installed into a hollow aluminum base, thereby improving the overall heat dissipation effect.

[0020] To fully utilize the heat dissipation effect of the aluminum base, the present invention also sets heat dissipation fins inside the hollow aluminum base to allow heat to dissipate better. In order to guide the heat and prevent heat from accumulating inside the aluminum base, the present invention also sets an external fan along the axis of the aluminum base. The external fan can remove the heat in time, so that the battery temperature can always be kept within a relatively stable range.

[0021] To better monitor battery temperature, this invention employs a dual-path temperature detection structure, which simultaneously places a first temperature sensor and a second temperature sensor at the front and rear ends of the battery, respectively, to capture the battery temperature from the front and rear ends. This allows the robotic arm to promptly handle the situation when the battery temperature rises to a threshold, preventing any impact on the discharge process at other locations.

[0022] To ensure the stability of the entire discharge process and avoid instability, this invention sets up a discharge limiting structure to limit the battery. However, to avoid the possibility of fire affecting the discharge limiting structure, this invention sets the discharge limiting structure inside the battery discharge mounting frame, with only a lever protruding from the surface of the battery discharge mounting frame. The lever moves the battery to abut against the copper plate, and the abutting method at the end also facilitates heat dissipation to the outside. Attached Figure Description

The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] Reference Figures 1-10As shown, a waste battery recycling and discharging device includes: a measuring platform 16 for measuring battery dimensions, a milling section discharge conveyor belt arranged on the side of the measuring platform 16 near the discharge end, and several three-dimensional storage cabinets 30 arranged on both sides of the milling section discharge conveyor belt; an adaptive distribution and adjustment structure 31, including a discharge robot mounting platform 311 arranged on the milling section discharge conveyor belt, on which loading and unloading robots 312 are mounted. The loading and unloading robots 312 clamp the batteries conveyed from the milling section discharge conveyor belt into the cabinets of the empty three-dimensional storage cabinets 30, and remove the discharged batteries and move them to the milling section discharge conveyor belt; a discharge device, including several battery discharge mounting racks 21 arranged on the three-dimensional storage cabinets 30, with two discharge modules 22 arranged on each battery discharge mounting rack 21. Copper plates 27 are fixed to each discharge module 22, and the copper plates 27 are connected to the discharge cabinet 32 ​​through terminals. The discharge module 22 is equipped with a heat dissipation structure, and the discharge module 22 is equipped with a discharge limiting structure 23 facing upwards. The battery discharge rack 21 is equipped with a dual-channel temperature detection structure 24. When the robot loads the battery onto the battery discharge rack 21, the discharge limiting structure 23 pushes the battery onto the discharge module 22, so that the battery terminals contact the copper sheet 27 and energize the terminals to discharge the battery. The current distribution structure includes several discharge cabinets 32 installed inside the automated storage cabinet 30. All the discharge cabinets 32 are connected to the same terminal. The number of discharge cabinets 32 corresponds one-to-one with the number and position of the battery discharge racks 21. The encoder of the measuring table 16 is electrically connected to the loading and unloading robot 312. The loading and unloading robot 312 is electrically connected to the discharge cabinets 32. When the loading and unloading robot 312 transfers the measured battery to the corresponding battery discharge rack 21, the discharge cabinet 32 ​​corresponding to the battery discharge rack 21 outputs a current of the corresponding size according to the size of the battery.

[0038] Existing technologies employ some automated storage and retrieval systems (AS / RS) for battery storage. However, the layout of the entire warehouse is narrow, the loading and unloading paths are complex, and the loading and unloading stages need to be completely separated. Furthermore, the small spacing between the compartments can easily affect the surrounding batteries. Therefore, this invention first adopts an adaptive distribution and adjustment structure 31, using a loading and unloading robot 312 to replace manual loading and unloading, thereby avoiding potential dangers associated with manual loading. The AS / RS cabinet 30 is positioned at both ends, with the loading and unloading robot 312 positioned in the center, allowing it to reach each compartment of the AS / RS cabinet 30. During the loading interval, the discharged batteries are removed, thus forming a virtuous cycle.

[0039] To reduce the number of loading / unloading robots 312 and avoid multiple reciprocating movements of the loading / unloading robots 312, the output end of the loading / unloading robot 312 of the present invention is provided with a dual-station mounting plate 3121. The lower end of the dual-station mounting plate 3121 is provided with two transfer stations 3122. The transfer stations 3122 are provided with bidirectional clamping motor units 3123, so that the unloading of the other station can be completed while loading, thereby reducing the number of processes.

[0040] Because batteries have different specifications and different charge contents, if batteries of different specifications are discharged with the same current, either incomplete discharge or excessive temperature will occur. Therefore, this invention uses a current distribution structure to set up multiple discharge cabinets 32 in the automated storage cabinet 30, so that different current outputs can be achieved in different battery discharge racks 21. First, the battery specifications are measured by the measuring table 16. Then, the loading and unloading robot 312 clamps the battery to any battery discharge rack 21. The discharge cabinet 32 ​​in the battery discharge rack 21 is connected with the battery size information obtained by the loading and unloading robot 312, and the specifications are compared with the specifications stored in the database, so as to output the optimal current corresponding to the battery size, so that the battery in the discharge can achieve the best discharge effect, and the discharge is thorough and fast.

[0041] Existing technologies directly use high current for discharge, resulting in very fast discharge speeds. However, under high power conditions, the battery temperature rises rapidly, easily leading to overheating, fire, spontaneous combustion, or explosion, posing a significant safety risk. Therefore, this invention addresses this by directly mounting a heat dissipation structure on the discharge module 22 and using a discharge limiting structure 23 to push the battery into contact with the discharge module 22. This allows heat to be promptly dissipated into the discharge module 22 and quickly discharged, thus preventing overheating and fire even with slightly higher currents.

[0042] To improve the heat dissipation effect of the discharge module 22 and avoid the disadvantage of solid structure in heat dissipation, the discharge module 22 in this embodiment includes a module mounting base 221 locked on the battery discharge mounting frame 21. A hollow aluminum base 222 is locked on the module mounting base 221, and the copper sheet 27 is locked on the aluminum base 222. The position where the copper sheet 27 of the discharge module 22 is installed is made into a hollow aluminum base 222, which can improve the overall heat dissipation effect. The module mounting base 221 provides certain support and fixation, so that the aluminum base 222 has a certain pressure bearing capacity.

[0043] To fully utilize the heat dissipation effect of the aluminum base 222, the heat dissipation structure in this embodiment includes several heat dissipation fins 251 and an external fan 252. The heat dissipation fins 251 are disposed on the four sides inside the aluminum base 222, and the external fan 252 is disposed on the axial direction of one of the aluminum bases 222. The heat generated during battery discharge is dissipated to the inner wall of the aluminum base 222 through the heat dissipation fins 251 and blown away by the external fan 252. The heat dissipation fins 251 are disposed inside the hollow aluminum base 222 to better dissipate heat. In order to guide the heat and avoid heat accumulation inside the aluminum base 222, the present invention also provides an external fan 252 on the axial direction of the aluminum base 222. The external fan 252 can dissipate heat in a timely manner, so that the battery temperature can always be kept within a relatively stable range.

[0044] In order to make the heat dissipation fins 251 as long as possible, the ends of the heat dissipation fins 251 on the same side in this embodiment are formed into an arc-shaped surface, so that the heat dissipation fins 251 can achieve the maximum heat dissipation effect without affecting each other.

[0045] To improve overall strength and make room for the dual-channel temperature detection structure 24 during installation, the module mounting base 221 in this embodiment includes a module mounting plate 2211 for locking the aluminum base 222. A U-shaped plate 2212 is integrally formed between the two module mounting plates 2211. The dual-channel temperature detection structure 24 is arranged on the projection line of the opening of the U-shaped plate 2212. Through the integrally formed module mounting plate 2211 and U-shaped plate 2212, the temperature control of the module mounting base 221 is enhanced.

[0046] To better monitor the battery temperature, the dual-channel temperature detection structure 24 in this embodiment includes a first temperature sensor 241 disposed on one side of the U-shaped plate 2212, and a second temperature sensor 242 disposed opposite to the first temperature sensor 241. The dual-channel temperature detection structure 24 means that the first temperature sensor 241 and the second temperature sensor 242 are disposed at the front and rear ends of the battery, respectively, to capture the battery temperature from the front and rear ends. When the battery temperature rises to the threshold, it can be processed in time by the robotic arm to avoid affecting the discharge operation at other locations.

[0047] To ensure the stability of the entire discharge process and avoid instability, this invention sets up a discharge limiting structure 23 to limit the battery. However, to avoid the possibility of fire affecting the discharge limiting structure 23, the battery discharge mounting frame 21 in this embodiment is provided with a clearance groove 211. The discharge limiting structure 23 includes a discharge push rod motor 231 disposed inside the battery discharge mounting frame 21. A heightening plate 232 that penetrates the clearance groove 211 is connected to the baffle at the end of the discharge push rod motor 231. The width of the heightening plate 232 is smaller than the width of the clearance groove 211. A lever 233 is connected to the upper end of the heightening plate 232. The discharge limiting structure 23 is disposed inside the battery discharge mounting frame 21, with only the lever 233 protruding from the surface of the battery discharge mounting frame 21. The lever 233 moves the battery to abut against the copper plate, and the abutment method at the end also facilitates heat dissipation to the outside.

[0048] During the retraction of the dial plate 233, a limit post 26 is provided on the side of the dial plate 233 away from the discharge module 22 to limit its movement. In order to ensure the stability of the discharge push rod motor 231 during movement, a guide post 234 is provided on the baffle at the end of the discharge push rod motor 231. The guide post 234 is sleeved on a discharge guide rod 235. The discharge guide rod 235 is fixed at both ends inside the battery discharge mounting frame 21 so that the discharge push rod motor 231 can be guided when it is pushed forward and retracted.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
