Description

Technical Field

[0001] This utility model relates to the field of battery recycling equipment technology, and in particular to a battery short-circuit discharge device. Background Technology

[0002] As time goes by, lithium batteries that have reached the end of their service life are entering the retirement stage. Currently, the mainstream process for battery recycling is to crush the battery and recover valuable metals. However, if there is residual electrical energy in the battery, a large amount of energy will be released during the crushing process, igniting the electrolyte and even causing an explosion. For safety reasons, the battery must be completely discharged before crushing.

[0003] Currently, the safest and most mature discharge method is external resistance discharge, but resistance discharge generally takes several hours and is inefficient. While the nail-driving discharge process can complete discharge in tens of minutes, significantly improving efficiency, the excessively high discharge rate can cause the battery to swell or even burn, posing a serious danger. Furthermore, the nail-driving discharge process leaves a large number of nails inside the battery, which may damage downstream crushing equipment during subsequent battery processing. Moreover, the nails can string materials together, preventing them from being broken down and separated, requiring additional nail separation processes and significantly increasing battery recycling costs. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a battery short-circuit discharge device.

[0005] The solution to the technical problem of this utility model is: A battery short-circuit discharge device, comprising: The water tank has a first workstation and a second workstation. A conveying assembly is disposed in the water tank and is used to sequentially convey batteries to the first workstation and the second workstation; The screw-in assembly includes a first clamping component and a screw-in driving component. The first clamping component is used to clamp the drill bit, and the output end of the screw-in driving component is connected to the first clamping component to drive the first clamping component to screw the drill bit into the battery. The first shifting component is driven to drive the screw-in driving component to move in and out of the first working station; The unscrewing assembly includes a second clamping component and an unscrewing drive component. The second clamping component is used to clamp the drill bit, and the output end of the unscrewing drive component is connected to the second clamping component to drive the second clamping component to rotate the drill bit out of the battery. The second shifting component is driven to drive the rotation driving component to move the rotation driving component in and out of the second working station.

[0006] This invention has at least the following beneficial effects: the conveying component transports the battery, the first shifting component drives the screw-in component to move onto the battery, and the screw-in component screws the drill bit into the battery, causing a short circuit discharge between the positive and negative electrodes, resulting in high discharge efficiency; cooling water can be added to the water tank, and during the battery discharge process, the cooling water can absorb the battery heat and isolate the battery from the air, preventing the battery from exploding or burning, thus greatly improving the safety of the discharge process; after the discharge is completed, the second shifting component drives the unscrewing component to move onto the battery, and the unscrewing component removes the drill bit from the battery, which can avoid the drill bit affecting the subsequent battery recycling process, prevent the downstream equipment from being damaged by the drill bit, and reduce the maintenance cost of the battery recycling system.

[0007] As a further improvement to the above technical solution, the conveying assembly includes a first conveyor line, a second conveyor line, a third conveyor line, and two first lifting components. The second conveyor line and the third conveyor line are respectively located at the inlet end and the outlet end of the first conveyor line. The two first lifting components are respectively driven connected to the second conveyor line and the third conveyor line to drive the second conveyor line and the third conveyor line to rise above the first conveyor line or fall to the same height as the first conveyor line. The first workstation is located above the first conveyor line, and the second workstation is located above the third conveyor line.

[0008] Because the second conveyor line can rise, it facilitates the transfer of batteries to the battery short-circuit discharge equipment for short-circuit discharge, eliminating the need for operators to insert their hands or robotic arms into the cooling water tank to discharge the batteries. Furthermore, since the third conveyor line can be driven upwards by the first lifting component, it allows the unscrewing assembly to be moved to the precise position above the drill bit by the second shifting assembly, enabling the unscrewing action. This also facilitates the removal of the discharged batteries from the battery short-circuit discharge equipment for the next processing step.

[0009] As a further improvement to the above technical solution, the second and third conveyor lines each include a conveyor belt and a conveyor drive component. The conveyor drive component is driven and connected to the conveyor belt. The conveyor belt has multiple mesh openings that penetrate the upper and lower surfaces of the conveyor belt. During the lifting and lowering process of the second and third conveyor lines, cooling water can smoothly pass through the conveyor belts of the second and third conveyor lines, preventing water splashing during lifting and lowering.

[0010] As a further improvement to the above technical solution, the battery short-circuit discharge device further includes: A rotary conveyor for conveying the drill bit, wherein the inlet end of the rotary conveyor extends below the second shifting assembly, and the outlet end of the rotary conveyor extends below the first shifting assembly; The first shifting component is configured to drive the infeed drive member to travel back and forth between the outlet end of the rotary conveyor and the first station; the second shifting component is configured to drive the outfeed drive member to travel back and forth between the inlet end of the rotary conveyor and the second station.

[0011] The rotary conveyor can automatically transport the drill bit removed from the battery to below the first shifting component, so that it can be gripped by the screw-in component and used, realizing the automatic recycling of the drill bit.

[0012] As a further improvement to the above technical solution, a limiting block is provided on the outer periphery of the drill bit, and a slot is provided on the rotary conveyor line. When the rotary conveyor line transports the drill bit, the lower end of the drill bit is inserted into the slot, and the lower surface of the limiting block abuts against the upper surface of the rotary conveyor line. The drill bit remains vertical during movement under the limiting action of the limiting block and the upper surface of the rotary conveyor line, which facilitates the subsequent clamping of the drill bit by the first clamping component and also facilitates the vertical screwing of the drill bit into the battery.

[0013] As a further improvement to the above technical solution, the first station and the second station are each provided with at least one set of clamping components. Each set of clamping components includes two clamping plates and a linear drive component. The two clamping plates are located on both sides of the conveying component. The linear drive component is driven to connect with the clamping plates to drive the two clamping plates to move closer or further apart.

[0014] The clamping assembly can hold the battery in place, preventing it from shifting during the screwing-in or screwing-out process and thus affecting the screwing-in or screwing-out action.

[0015] As a further improvement to the above technical solution, the battery short-circuit discharge device further includes: A first acquisition component is disposed between the screw-in component and the screw-out component. The first acquisition component is configured to acquire the position information of the drill bit on the battery and transmit the position information to the second shifting component.

[0016] By acquiring the position information of the drill bit through the first acquisition component, the unscrewing component can accurately remove the drill bit from the battery, preventing the drill bit from following the battery into the next process.

[0017] As a further improvement to the above technical solution, the battery short-circuit discharge device further includes: The second acquisition component is located at the inlet end of the conveying component. The second acquisition component is configured to acquire the size information of the battery and convey the size information to the first shifting component.

[0018] By acquiring the battery size information through the second acquisition component, the screw-in assembly can accurately screw the drill bit into the battery, effectively performing short-circuit discharge. This makes the battery short-circuit discharge device suitable for discharging batteries of different sizes, with strong compatibility.

[0019] As a further improvement to the above technical solution, the screw-in driving component includes a second lifting component and a first rotation driving component. The output end of the first shifting component is connected to the second lifting component, the output end of the second lifting component is connected to the first rotation driving component, and the output end of the first rotation driving component is connected to the first clamping component. The screw-out driving component includes a third lifting component and a second rotation driving component. The output end of the second shifting component is connected to the third lifting component, the output end of the third lifting component is connected to the second rotation driving component, and the output end of the second rotation driving component is connected to the second clamping component.

[0020] The cooperation between the first rotary drive component and the second lifting component allows the drill bit to rotate and move downwards simultaneously, thus enabling the drill bit to drill into the battery. The cooperation between the second rotary drive component and the third lifting component allows the drill bit to rotate and move upwards simultaneously, thus enabling the drill bit to rotate out of the battery.

[0021] As a further improvement to the above technical solution, the conveying assembly, the screw-in assembly, and the screw-out assembly are each provided in multiple sets, with each set of the conveying assembly corresponding to at least one set of the screw-in assembly and one set of the screw-out assembly. This arrangement allows for the simultaneous discharge of multiple batteries, thereby improving battery recycling efficiency. Attached Figure Description

[0029] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0030] Reference Figures 1 to 5 This utility model embodiment proposes a battery short-circuit discharge device that can safely and quickly perform short-circuit discharge treatment on waste batteries 1000, so as to facilitate the subsequent recycling of batteries 1000.

[0031] The battery short-circuit discharge equipment includes a water tank 100, a conveying assembly 200, a screw-in assembly 400, a screw-out assembly 600, a first shifting assembly 300, and a second shifting assembly 500. The water tank 100 has an upward-facing opening and is equipped with a first station and a second station. The water tank 100 is used to hold cooling water. The conveying assembly 200 is disposed within the water tank 100 and is used to sequentially convey the battery 1000 to the first station and the second station for processing.

[0032] The screw-in assembly 400 includes a first clamping component and a screw-in driving component. The first clamping component is used to clamp the drill bit 1010. The output end of the screw-in driving component is connected to the first clamping component. The first shifting component 300 is drivenly connected to the screw-in driving component. Under the driving action of the first shifting component 300, the screw-in driving component and the first clamping component can move in and out of the first station. Under the driving action of the screw-in driving component, the first clamping component can drive the clamped drill bit 1010 to be screwed into the battery 1000 located in the first station.

[0033] The unscrewing assembly 600 includes a second clamping component 630 and an unscrewing drive component. The second clamping component 630 can also clamp the drill bit 1010. The output end of the unscrewing drive component is connected to the second clamping component 630. The second shifting assembly 500 is drivenly connected to the unscrewing drive component. Under the driving action of the second shifting assembly 500, the unscrewing drive component and the second clamping component 630 can move in and out of the second station. Under the driving action of the unscrewing drive component, the second clamping component 630 can clamp the drill bit 1010 located on the battery 1000 in the second station and unscrew the drill bit 1010 from the battery 1000.

[0034] It is understood that the battery short-circuit discharge device of this embodiment can drill a hole and short-circuit the waste battery 1000 in a short time to complete the discharge action, greatly improving the discharge and recycling efficiency of the battery 1000. Moreover, since cooling water can be added to the water tank 100, the cooling water can absorb the heat of the battery 1000 and isolate the battery 1000 from the air, preventing the battery 1000 from burning during the discharge process, making the entire discharge process safer and more reliable.

[0035] Furthermore, since the drill bit 1010 can be unscrewed from the battery 1000 after it has been completely discharged via the unscrewing assembly 600, the drill bit 1010 can be reused, reducing recycling costs. Moreover, the removal of the drill bit 1010 will not affect subsequent recycling processes of the battery 1000, preventing materials inside the battery 1000 from becoming tangled together and unable to be separated, and will not damage subsequent crushing equipment, thus reducing the maintenance costs of the entire battery 1000 recycling system.

[0036] Reference Figures 1 to 3 In some embodiments, the conveying assembly 200 includes a first conveying line 210, a second conveying line 220, a third conveying line 230, and two first lifting components 240. The second conveying line 220, the first conveying line 210, and the third conveying line 230 are arranged sequentially along the moving direction of the battery 1000. That is, the second conveying line 220 is located at the entrance end of the first conveying line 210, and the third conveying line 230 is located at the exit end of the first conveying line 210. After the battery 1000 enters the second conveying line 220, it moves to the first conveying line 210 under the driving action of the second conveying line 220, and then moves to the third conveying line 230 under the driving action of the first conveying line 210, thereby realizing the position movement of the battery 1000 throughout the entire discharge process.

[0037] The first station is located above the first conveyor line 210, and the second station is located above the third conveyor line 230. That is, the drill bit 1010 is screwed in on the first conveyor line 210, and the drill bit 1010 is screwed out on the third conveyor line 230.

[0038] In this embodiment, the conveying assembly 200 conveys the battery 1000 in a straight line, driving the battery 1000 to move from left to right. The second conveying line 220, the first conveying line 210 and the third conveying line 230 are arranged sequentially from left to right.

[0039] It is worth noting that the two first lifting components 240 are drivenly connected to the second conveyor line 220 and the third conveyor line 230, respectively. Under the driving action of the first lifting components 240, the second conveyor line 220 and the third conveyor line 230 can be raised and lowered. Specifically, when rising, the second conveyor line 220 and the third conveyor line 230 can be higher than the upper surface of the first conveyor line 210, allowing the batteries 1000 located on the second conveyor line 220 and the third conveyor line 230 to be exposed above the cooling water surface of the water tank 100. When descending, the second conveyor line 220 and the third conveyor line 230 can descend to the same height as the first conveyor line 210, allowing the batteries 1000 located on the second conveyor line 220 to smoothly enter the first conveyor line 210, and the batteries 1000 located on the first conveyor line 210 can also smoothly enter the third conveyor line 230 after being discharged.

[0040] With this configuration, since the second conveyor line 220 can rise, it is convenient for operators to transfer the battery 1000 to the battery short-circuit discharge equipment for short-circuit discharge operation by manual placement or robotic arm placement. Operators do not need to put their hands or robotic arms into the cooling water of the water tank 100 to discharge the battery 100.

[0041] Since the third conveyor line 230 can be driven to rise by the first lifting component 240, it is easier for the unscrewing component 600 to move above the drill bit 1010 under the action of the second shifting component 500 and to unscrew the drill bit 1010. It is also convenient for the operator to take the discharged battery 1000 out of the battery short-circuit discharge device for the next process.

[0042] In some embodiments, the first lifting component 240 is a lifting cylinder.

[0043] In some embodiments, the second conveyor line 220 and the third conveyor line 230 respectively include a conveyor belt and a conveyor drive component. The conveyor drive component is driven to connect with the conveyor belt. The conveyor belt is provided with a plurality of mesh holes that penetrate through the upper and lower surfaces of the conveyor belt.

[0044] In this embodiment, the conveyor belt is a metal wire mesh belt. During the lifting and lowering process of the second conveyor line 220 and the third conveyor line 230, the cooling water can pass smoothly through the conveyor belt of the second conveyor line 220 and the third conveyor line 230 to prevent water splashing during lifting and lowering.

[0045] In some embodiments, the battery short-circuit discharge device further includes a rotary conveyor line 900 for conveying the drill bit 1010, with its inlet end extending below the second shifting assembly 500 and its outlet end extending below the first shifting assembly 300. During use, the first shifting assembly 300 can drive the screw-in assembly 400 back and forth between the outlet end of the rotary conveyor line 900 and the first station, while the second shifting assembly 500 can drive the screw-out assembly 600 back and forth between the inlet end of the rotary conveyor line 900 and the second station.

[0046] With this configuration, the drill bit 1010, which is screwed out from the battery 1000 via the screw-out component 600, can be moved onto the rotary conveyor line 900, and then conveyed to the area below the first shifting component 300 via the rotary conveyor line 900, where it is picked up and used by the screw-in component 400, thus realizing the automatic recycling of the drill bit 1010.

[0047] In some embodiments, refer to Figure 4 A limiting block 1020 is provided on the outer periphery of the drill bit 1010, and a slot 910 is provided on the rotary conveyor line 900. When the rotary conveyor line 900 conveys the drill bit 1010, the lower end of the drill bit 1010 is inserted into the slot 910, and the lower surface of the limiting block 1020 abuts against the upper surface of the rotary conveyor line 900.

[0048] Understandably, the drill bit 1010 maintains a vertical position during movement under the constraint of the limiting block 1020 and the upper surface of the rotary conveyor 900. This facilitates the subsequent clamping of the drill bit 1010 by the first clamping component and also allows the drill bit 1010 to be vertically screwed into the battery 1000, eliminating the need for an additional mechanism to adjust the orientation of the drill bit 1010. Furthermore, the limiting block 1020 also limits the depth to which the drill bit 1010 screws into the battery 1000, ensuring it contacts the positive and negative electrodes inside the battery 1000 while keeping the upper end of the drill bit 1010 exposed. This also facilitates the clamping of the drill bit 1010 on the battery 1000 by the second clamping component 630, making it easier for the unscrewing assembly 600 to unscrew the drill bit 1010.

[0049] In some embodiments, a baffle is provided at the outlet end of the rotary conveyor 900. The baffle can block the drill bit 1010 that moves to the outlet end of the rotary conveyor 900, so that the drill bit 1010 stops below the first shifting component 300 and prevents the drill bit 1010 from continuing to move.

[0050] In some embodiments, the battery short-circuit discharge device further includes a clamping assembly 250. Specifically, at least one set of clamping assemblies 250 is provided at the first station and the second station respectively. The clamping assembly 250 is used to clamp the battery 1000 on the conveying assembly 200, allowing the battery 1000 to stably perform the screwing-in and screwing-out actions of the drill bit 1010. (Refer to...) Figure 5 Each clamping assembly 250 includes two clamping plates 252 and a linear drive component 251. The two clamping plates 252 are located on both sides of the conveying assembly 200. That is, when the battery 1000 moves under the driving action of the conveying assembly 200, the battery 1000 can enter the space between the two clamping plates 252. The linear drive component 251 is driven to connect with the clamping plates 252 to drive the two clamping plates 252 to move closer or further away from each other, thereby clamping or releasing the battery 1000.

[0051] In this embodiment, refer to Figure 5 Each clamping assembly 250 includes two clamping plates 252 and two linear drive components 251. The two linear drive components 251 are respectively drivenly connected to the two clamping plates 252, driving the two clamping plates 252 to move, thereby clamping or releasing the battery 1000. In this embodiment, the linear drive components 251 for driving the movement of the clamping plates 252 are arranged on the front and rear sides of the conveying assembly 200, and the two clamping plates 252 are located between the two linear drive components 251.

[0052] In other embodiments, in each clamping assembly 250, one clamping plate 252 is fixed in position, while the other clamping plate 252 moves under the action of the linear drive component 251, thereby changing the distance between the two clamping plates 252 and achieving clamping or loosening of the battery 1000.

[0053] It is understood that the linear drive component 251 can be a cylinder, an electric cylinder, etc. In this embodiment, a waterproof cylinder with waterproof performance is used to drive the clamping plate 252 to move.

[0054] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3 The battery short-circuit discharge device also includes a first acquisition component 700, which is disposed between the screw-in component 400 and the screw-out component 600. The first acquisition component 700 can acquire the position information of the drill bit 1010 on the battery 1000 and transmit the position information to the second shift component 500. The second shift component 500 drives the screw-out component 600 to move above the drill bit 1010 according to the specific position information of the drill bit 1010, so that the screw-out component 600 can accurately clamp and screw out the drill bit 1010 on the battery 1000.

[0055] In some embodiments, the second shifting component 500 is provided with a second control processing module, which is connected to the first acquisition component 700 via wired or wireless means, thereby acquiring the position information acquired by the first acquisition component 700 and calculating the displacement amount required for the rotating component 600 to move, so as to control the rotating component 600 to move.

[0056] In some embodiments, the battery short-circuit discharge device further includes a second acquisition component 800, which is disposed at the inlet end of the conveying component 200. The second acquisition component 800 can acquire the size information of the battery 1000 and convey the size information to the first shifting component 300. The first shifting component 300 determines the position where the drill bit 1010 is screwed in according to the size information of the battery 1000 and drives the screwing component 400 to move above the preset position, so that the drill bit 1010 can be accurately screwed in to the position that contacts the positive and negative electrode plates inside the battery 1000.

[0057] In some embodiments, the first shifting component 300 is also provided with a first control processing module, which is connected to the second acquisition component 800 via wired or wireless means. It can acquire the size information acquired by the second acquisition component 800, calculate the displacement required for the screw-in component 400 to move, and control the screw-in component 400 to move.

[0058] In some embodiments, the battery short-circuit discharge device further includes a host computer. The first acquisition component 700, the second acquisition component 800, the first shift component 300, and the second shift component 500 are respectively connected to the host computer via wired or wireless means. The position information acquired by the first acquisition component 700 and the size information acquired by the second acquisition component 800 are respectively transmitted to the host computer. After calculating the displacement of the screw-out component 600 and the screw-in component 400, the host computer sends commands to the second shift component 500 and the first shift component 300. The second shift component 500 drives the screw-out component 600 to move, and the first shift component 300 drives the screw-in component 400 to move.

[0059] In some embodiments, the first acquisition component 700 and the second acquisition component 800 are cameras, which acquire the position of the drill bit 1010 and the size of the battery 1000 through image recognition.

[0060] In some embodiments, the screw-in drive component includes a second lifting component 410 and a first rotation drive component 420. The output end of the first shifting component 300 is connected to the second lifting component 410, the output end of the second lifting component 410 is connected to the first rotation drive component 420, and the output end of the first rotation drive component 420 is connected to the first clamping component. The screw-out drive component includes a third lifting component 610 and a second rotation drive component 620. The output end of the second shifting component 500 is connected to the third lifting component 610, the output end of the third lifting component 610 is connected to the second rotation drive component 620, and the output end of the second rotation drive component 620 is connected to the second clamping component 630.

[0061] Understandably, the cooperation between the first rotary drive component 420 and the second lifting component 410 enables the drill bit 1010 to rotate and move downward simultaneously, thereby drilling the drill bit 1010 into the battery 1000. The cooperation between the second rotary drive component 620 and the third lifting component 610 enables the drill bit 1010 to rotate and move upward simultaneously, thereby rotating the drill bit 1010 out of the battery 1000.

[0062] The first rotary drive component 420 and the second rotary drive component 620 can be motors, and the second lifting component 410 and the third lifting component 610 can be electric cylinders.

[0063] In some embodiments, multiple sets of conveying components 200, screw-in components 400, and screw-out components 600 are provided, with each set of conveying components 200 corresponding to at least one set of screw-in components 400 and one set of screw-out components 600. Specifically, the conveying components 200 drive the battery 1000 to move in the left-right direction, and the multiple sets of conveying components 200 are arranged sequentially in the front-back direction. This arrangement allows for the simultaneous discharge of multiple batteries 1000, greatly improving the battery 1000 recycling efficiency.

[0064] In some embodiments, the conveying assembly 200 is provided in two sets, each set of conveying assemblies 200 corresponding to two sets of screw-in assemblies 400 and two sets of screw-out assemblies 600. The two conveying assemblies 200 convey the battery 1000, and two drill bits 1010 are screwed into each battery 1000 to achieve a short circuit between the positive and negative terminals of the battery 1000. The first shifting assembly 300 and the second shifting assembly 500 can be lead screw motors, capable of driving the screw-in assembly 400 or the screw-out assembly 600 to move in the back-and-forth direction.

[0065] In some embodiments, the first shifting component 300 and the second shifting component 500 are respectively provided in two sets. Both sets of the first shifting component 300 are located above the first work station, and both sets of the second shifting component 500 are located above the second work station. Each set of the first shifting component 300 drives two sets of screw-in components 400 to move, and each set of the second shifting component 500 drives two sets of screw-out components 600 to move.

[0066] In some embodiments, two sets of rotary conveyor lines 900 are provided, and the two sets of rotary conveyor lines 900 are located on the front and rear sides of the water tank 100, respectively. When the first shifting component 300 drives the two sets of screw-in components 400 to move, one set of screw-in components 400 in the first shifting component 300 moves to the first station and performs the screw-in action of the drill bit 1010. At the same time, the other set of screw-in components 400 moves above the rotary conveyor line 900 to perform the clamping action of the drill bit 1010. When the second shifting component 500 drives the two sets of unscrewing components 600 to move, one set of unscrewing components 600 in the second shifting component 500 moves to the second station and performs the unscrewing action of the drill bit 1010. At the same time, the other set of unscrewing components 600 moves above the rotary conveyor line 900 to perform the placement action of the drill bit 1010. This arrangement can greatly improve the screw-in and unscrewing efficiency of the drill bit 1010, thereby improving the short-circuit discharge efficiency of the battery 1000.

[0067] In some embodiments, the battery short-circuit discharge device also includes a robotic arm that can replace manual handling and automatically load and unload batteries 1000, further reducing the labor intensity of workers.

[0068] In some embodiments, the battery 1000 circuit discharge device further includes an exhaust gas treatment component. When the drill bit 1010 is screwed into the battery 1000, the gap between the drill bit 1010 and the battery 1000 can discharge the gas generated by the internal short circuit of the battery 1000, preventing the battery 1000 from exploding. The exhaust gas treatment component can extract the discharged gas and recycle the discharged gas.

[0069] When using the battery short-circuit discharge device of this embodiment to short-circuit discharge the battery 1000, the operator first places the battery 1000 onto the second conveyor line 220, which is driven to rise above the water surface by the first lifting component 240. The second acquisition component 800 automatically acquires the external dimensions of the battery 1000 and uploads them to the host computer, which calculates the position of the drill bit 1010. The second conveyor line 220 is submerged in the cooling water under the driving action of the first lifting component 240, and drives the battery 1000 to move towards the first conveyor line 210.

[0070] When the battery 1000 moves to the first station on the first conveyor line 210, the clamping assembly 250 at the first station clamps the battery 1000 stably. The first shifting assembly 300 receives the instruction from the host computer and drives the screwing assembly 400 to move. The screwing assembly 400 clamps the drill bit 1010 from the rotary conveyor line 900 and screws the drill bit 1010 into the battery 1000 located in the water. The drill bit 1010 contacts the positive and negative electrodes inside the battery 1000, performing a short-circuit discharge. The battery 1000 releases a large amount of heat, and the cooling water absorbs the heat from the battery 1000 and isolates the battery 1000 from the air, preventing the battery 1000 from burning.

[0071] The battery 1000 continues to move and discharge under the drive of the first conveyor line 210, taking 10 to 15 minutes. Then, the battery 1000 moves to the third conveyor line 230, reaching the second workstation. The third conveyor line 230 rises above the water surface under the drive of the first lifting component 240. The first acquisition component 700 automatically identifies the position of the drill bit 1010 and uploads the data to the host computer. The clamping component 250 at the second workstation clamps and fixes the battery 1000. The second shifting component 500 receives instructions from the host computer and drives the rotating component 600 to move above the drill bit 1010 on the battery 1000. The rotating component rotates the drill bit 1010 off the battery 1000 and places it on the rotary conveyor line 900. The drill bit 1010 returns to below the first shifting component 300 for use under the action of the rotary conveyor line 900.

[0072] After the drill bit 1010 is removed from the battery 1000, the clamping assembly 250 at the second station releases the battery 1000, and the battery 1000 continues to move along the third conveyor line 230. The operator removes the discharged battery 1000 from the third conveyor line 230 and sends it to the next process.

[0073] The battery 1000 discharge device of this embodiment can complete the drilling and short-circuiting of a battery 1000 in just 6 seconds. After the drill bit 1010 is driven in, the discharge is basically completed in 10 to 15 minutes, which is extremely efficient. Moreover, the battery 1000 discharges in water, which can prevent combustion, and the whole process is safe and reliable. Since the drill bit 1010 is removed by the unscrewing component 600 after the battery 1000 has finished discharging, it can avoid the drill bit 1010 residue damaging the subsequent battery 1000 recycling equipment or increasing the screening difficulty of subsequent processes. In addition, since a second collection component 800 is provided, it can identify the size of the battery 1000 and automatically adjust the position of the screw-in component 400 according to the size information of the battery 1000, which is suitable for use with batteries 1000 of different sizes and has strong compatibility.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
