After a period of use, the electrode materials of power batteries will expand, contract, and even the performance of the active substances in the electrode materials will change, resulting in a decrease in battery capacity and scrapping.

[0003] When power batteries are scrapped, if not properly processed, serious safety hazards and environmental pollution will be caused, and at the same time, a huge waste of resources will also occur. In order to recycle cobalt, copper, lithium, aluminum, etc. in waste power batteries, chemical methods such as extraction method, biological leaching method, ion exchange method, etc. are commonly used at present. Before that, pretreatment procedures such as discharging and crushing of power battery products are usually required. However, in the discharging pretreatment process, the battery needs to be fixed in the discharging box of the discharging device first, and then the battery is discharged by the needle punching mechanism of the discharging device.

[0038] To better understand the technical solutions and beneficial effects of this disclosure, the following further describes this disclosure in detail with specific embodiments:

[0039] As Figures 1 to 6 shown, the battery cell discharging device 10 of an embodiment of this disclosure includes a needle punching mechanism 100, a control mechanism 200 and a feeding mechanism 300; the needle punching mechanism 100 includes an annular track assembly 110, a roller assembly 120, a sliding frame assembly 130 and a needle punching assembly 140. The annular track assembly 110 is provided with a convex portion 111, and the convex portion 111 is further provided with a groove portion 1101. The convex portion 111 and the groove portion 1101 are connected end to end, and the position of the convex portion 111 is higher than that of the groove portion 1101; the roller assembly 120 is rotatably connected to the sliding frame assembly 130, the roller assembly 120 is slidably arranged on the annular track assembly 110, and the roller assembly 120 drives the sliding frame assembly 130 to perform a circular motion along the annular track assembly 110; the needle punching assembly 140 is connected to the sliding frame assembly 130, and the needle punching assembly 140 can perform telescopic needle punching on the battery.

[0040] Further, the control mechanism 200 includes a control component 210 and a transmission component 220. The control component 210 and the transmission component 220 are respectively connected to the sliding frame component 130. The output end of the transmission component 220 is connected to the roller component 120. The control component 210 includes an abutting portion. The abutting portion of the control component 210 is used to abut against the protruding portion 111 or the groove portion 1101. When the abutting portion of the control component 210 abuts against the groove portion 1101, a first control signal is output. The control component 210 controls the transmission component 220 to rotate at a low speed according to the first control signal. The transmission component 220 then drives the roller component 120 to rotate at a low speed. When the abutting portion of the control component 210 abuts against the protruding portion 111, a second control signal is output. The control component 210 controls the transmission component 220 to rotate at a high speed according to the second control signal. The transmission component 220 then drives the roller component 120 to rotate at a high speed; The feeding mechanism 300 is arranged below the groove portion 1101, and the feeding mechanism 300 is used to convey the battery.

[0041] In this embodiment, the battery is placed on the feeding mechanism 300. The initial end of the groove portion 1101 adjacent to the battery insertion end of the feeding mechanism 300. When the sliding frame component 130 moves to the groove portion 1101, the abutting portion of the control component 210 abuts against the groove portion 1101, so that the control component 210 controls the transmission component 220 to rotate at a low speed. The transmission component 220 drives the roller component 120 to rotate at a low speed, so that the sliding frame component 130 slides at a low speed on the annular track component 110. When the sliding frame component 130 slides at a low speed on the annular track component 110, the battery is located between the feeding mechanism 300 and the acupuncture component 140. The acupuncture component 140 pierces the battery, causing the battery to discharge. When the sliding frame component 130 moves to the conveying end of the feeding mechanism 300, the battery is separated from the acupuncture component 140; When the sliding frame component 130 moves to the protruding portion 111, when the abutting portion of the control component 210 abuts against the protruding portion 111, the control mechanism 200 controls the transmission component 220 to rotate at a high speed. The transmission component 220 drives the roller component 120 to rotate at a high speed, so that the sliding frame component 130 slides at a high speed on the annular track component 110, so that the sliding frame component 130 quickly moves to the initial end of the groove portion 1101.

[0042] In the above-mentioned battery cell discharging device 10, when the abutting portion of the control assembly 210 abuts against the groove portion 1101, the control assembly 210 controls the transmission assembly 220 to drive the roller assembly 120 to rotate at a low speed, so that the sliding frame assembly 130 slides at a low speed on the annular track assembly 110. When the battery acupuncture assembly 140 performs acupuncture, the sliding frame assembly 130 drives the battery to slide at a low speed, so that the battery has a long continuous discharging time, and thus the battery discharges sufficiently; when the abutting portion of the control mechanism 210 abuts against the protruding portion 111, the control assembly 210 controls the transmission assembly 220 to drive the roller assembly 120 to rotate at a high speed, so that the sliding frame assembly 130 slides at a high speed on the annular track assembly 110, and the sliding frame assembly 130 quickly moves along the annular track assembly 110 to the initial end of the groove portion 1101, realizing continuous discharging of multiple batteries, thereby improving the discharging efficiency of the battery cell discharging device 10 for the battery.

[0043] As Figure 1 and Figure 2 shown, in one embodiment, the number of the roller assembly 120, the sliding frame assembly 130, the acupuncture assembly 140 and the control mechanism 200 is multiple. Each sliding frame assembly 130 is respectively connected with a corresponding roller assembly 120, acupuncture assembly 140 and control mechanism 200. The multiple sliding frame assemblies 130 are sequentially slidably arranged on the annular track assembly 110, and the multiple acupuncture assemblies 140 respectively perform acupuncture on a battery, so that the multiple batteries discharge simultaneously, improving the discharging efficiency of the battery cell discharging device 10.

[0044] As Figure 1 and Figure 2 shown, in one embodiment, the transmission assembly 220 includes a transmission motor 221, a first gear 222 and a second gear 223. The transmission motor 221 is connected to the sliding frame assembly 130, the first gear 222 is connected to the output end of the transmission motor 221, the second gear 223 is connected to the roller assembly 120, and the first gear 222 meshes with the second gear 223. In this embodiment, the radius of the second gear 223 is greater than the radius of the first gear 222. The second gear 223 is a large gear, and the first gear 222 is a small gear. By meshing the second gear 223 with the first gear 222, the torque of the driven roller assembly 120 is amplified, so that the transmission motor 221 can more easily drive the roller assembly 120 to rotate.

[0045] As Figures 3 to 5As shown, in one embodiment, the control component 210 includes a current control member 211, a power supply 212, a high-speed circuit board 213, a low-speed circuit board 214, and an energizing rod assembly 215. The current control member 211 is provided with an installation groove 2101. The current control member 211 is installed on the sliding frame assembly 130. The high-speed circuit board 213 is disposed on the top of the installation groove 2101, and the low-speed circuit board 214 is disposed on the bottom of the installation groove 2101. The high-speed circuit board 213 and the low-speed circuit board 214 are respectively electrically connected to the current control member 211. The sliding frame assembly 130 is provided with a through hole 1301, and the through hole 1301 communicates with the installation groove 2101. The energizing rod assembly 215 movably passes through the through hole 1301. One end of the energizing rod assembly 215 is disposed in the installation groove 2101, and the other end of the energizing rod assembly 215 is used to abut against the protrusion 111 or the groove portion 1101. The power supply 212 is installed on the sliding frame assembly 130. The current control member 211, the energizing rod assembly 215, and the transmission assembly 220 are respectively electrically connected to the power supply 212. In this embodiment, when one end of the energizing rod assembly 215 abuts against the protrusion 111, the other end of the energizing rod assembly 215 rises to contact the high-speed circuit board 213, so that the current control member 211 controls signal two. The current control member 211 outputs a larger current to the transmission assembly 220 according to the control signal two. When the transmission assembly 220 rotates at a high speed, it drives the sliding frame assembly 130 to slide at a high speed on the first through groove 1102. When one end of the energizing rod assembly 215 abuts against the groove portion 1101, the other end of the energizing rod assembly 215 abuts against the low-speed circuit board 214, so that the current control member 211 outputs control signal one. The current control member 211 outputs a smaller current to the transmission assembly 220 according to the control signal one. When the transmission assembly 220 rotates at a low speed, it drives the sliding frame assembly 130 to slide at a low speed on the first through groove 1102. Thus, when the battery is punctured by the puncturing assembly 140, the sliding frame assembly 130 is in a low-speed state, and the battery discharges for a long time, so that the battery is fully discharged. After the puncturing process is completed, the sliding frame assembly 130 slides at a high speed to the initial end of the groove portion 1101, and then punctures the next battery, shortening the operating speed of the battery single-cell discharging device 10, thereby improving the discharging efficiency of the battery.

[0046] As Figure 4 and Figure 5As shown, in one embodiment, the energized rod assembly 215 includes a movable plate 2151, a guide post 2152, a push rod 2153, a spring 2154, and a conductive contact rod 2155. The movable plate 2151 is provided with a sliding hole 2102, and the guide post 2152 movably passes through the sliding hole 2102. A spring 2154 is sleeved on the guide post 2152. One end of the spring 2154 abuts against the high-speed electric plate 213, and the other end of the spring 2154 abuts against the movable plate 2151. The conductive contact rod 2155 is connected to the movable plate 2151. Both ends of the conductive contact rod 2155 are respectively used for contacting the high-speed electric plate 213 and the low-speed electric plate 214. The conductive contact rod 2155 is also electrically connected to the power supply 212. One end of the push rod 2153 is connected to the movable plate 2151. The push rod 2153 movably passes through the through hole 1301. The other end of the push rod 2153 is used for abutting against the convex portion 111 or the groove portion 1101. In this embodiment, the spring 2154 abuts against the movable plate 2151, so that the movable plate 2151 drives the push rod 2153 to abut against the annular track assembly 110. When the push rod 2153 abuts against the convex portion 111, the position of the push rod 2153 rises, so that the push rod 2153 drives the position of the movable plate 2153 to rise. The movable plate 2153 drives the conductive contact rod 2155 to contact the high-speed electric plate 213, so that the current control member 211 outputs a larger current. The current control member 211 controls the transmission assembly 220 to rotate at a high speed. When the push rod 2153 abuts against the groove portion 1101, the position of the push rod 2153 drops, so that the push rod 2153 drives the position of the movable plate 2153 to drop. The movable plate 2153 drives the conductive contact rod 2155 to contact the low-speed electric plate 214, so that the current control member 211 outputs a smaller current. The current control member 211 controls the transmission assembly 220 to rotate at a low speed. When the sliding frame assembly 130 is displaced to different positions, the current control member 211 can accurately output different currents to the transmission assembly 220, thereby controlling the transmission assembly 220 to drive the sliding frame assembly 130 to slide at a high speed or a low speed.

[0047] As Figure 3 , Figure 6 and Figure 7As shown, in one embodiment, the roller assembly 120 includes a first roller 121 and a second roller 122. The first roller 121 is rotatably connected to the sliding frame assembly 130, and the output end of the control mechanism 200 is connected to the first roller 121. The second roller 122 is rotatably connected to the sliding frame assembly 130. The annular track assembly 110 includes a first track 112, a second track 113, and a third track 114. The second track 113 is disposed within the first track 112, and the third track 114 is disposed within the second track 113. A first through slot 1102 is formed between the first track 112 and the second track 113, and the first roller 121 is inserted through the first through slot 1102. The second track 113 is provided with a protrusion 111 and a groove 1101. A second through slot 1103 is formed between the second track 113 and the third track 114, and the second roller 122 is inserted through the second through slot 1103. In this embodiment, the first roller 121 is limited within the first through slot 1102, so that the first roller 121 is not easily disengaged from between the first track 112 and the second track 113. The second roller 122 is limited within the second through slot 1103, so that the second roller 122 is not easily disengaged from between the second track 113 and the third track 114. The first roller 121 and the second roller 122 jointly guide the sliding frame assembly 130 to perform a circular motion along the annular track assembly 110.

[0048] As Figure 1 , Figure 8 and Figure 9As shown, in one embodiment, the feeding mechanism 300 includes a box body 310, a limiting plate 320 and a transmission assembly 330. The box body 310 is disposed below the groove portion 1101. An access opening 3101 and a receiving cavity 3102 that communicate with each other in sequence are formed in the box body 310. The transmission assembly 330 is disposed in the receiving cavity 3102. The limiting plate 320 is connected to the inner wall of the box body 310. The limiting plate 320 divides the access opening 3101 into a placement inlet 3103 and a placement outlet 3104. The limiting plate 320 is provided with a needle-piercing through groove 3201 that communicates with the receiving cavity 3102. One end of the needle-piercing through groove 3201 communicates with the placement inlet 3103, and the other end of the needle-piercing through groove 3201 communicates with the placement outlet 3104. In this embodiment, the battery is placed on the transmission assembly 330 from the placement inlet 3103, and the transmission assembly 330 transports the battery in the direction of the placement outlet 3104. When the sliding frame assembly 130 moves to the groove portion 1101, the battery is located between the transmission assembly 330 and the limiting plate 320, and the needle-piercing assembly 140 is located above the battery. The needle-piercing assembly 140 pierces the battery through the needle-piercing through groove 3201, so that the battery discharges quickly. After the battery discharges, the needle-piercing assembly 140 contracts and pulls out from the battery. The limiting plate 320 abuts against the battery, so that the needle-piercing assembly 140 can be smoothly pulled out. The transmission assembly 330 transports the battery to below the placement outlet 3104, and the battery is taken out from the placement outlet 3104. The battery can be placed into the placement inlet 3103 manually or by a robot. When taking out the battery at the placement outlet 3104, it can be manually unloaded or unloaded by a robot. When taking out the battery at the placement outlet 3104, a discharge port can also be opened at the bottom of the box body 310. A receiving box is disposed below the discharge port. The discharge port is located below the transportation end of the transmission assembly 330. When the battery moves to the edge of the transmission assembly 330, it naturally falls off, and the battery enters the receiving box through the discharge port.

[0049] As Figure 1 and Figure 9 shown, in one embodiment, the transmission assembly 330 includes transmission rollers 331, a conveyor belt 332, a transmission motor 333 and support blocks 334. The number of transmission rollers 331 is multiple, and the multiple transmission rollers 331 are spaced apart. One transmission roller 331 is connected to the output end of the transmission motor 333. The conveyor belt 332 is sleeved on the multiple transmission rollers 331. The support blocks 334 are disposed between two transmission rollers 331. In this embodiment, when the needle-piercing assembly 140 pierces the battery, the battery is located above the support blocks 334. The support blocks 334 increase the support strength for the battery, so that the needle-piercing assembly 140 can smoothly pierce the battery.

[0050] In one of its embodiments, a large amount of heat is released when the battery is punctured. To prevent explosion or fire caused by overheating during the battery discharge process, a liquid is filled in the accommodation cavity 3102 so that the battery is immersed in the liquid. The heat released by the battery during the needle puncture is absorbed by the liquid, making the battery discharge process safer.

[0051] As Figure 9 shown, in one of the embodiments, the feeding mechanism 300 further includes a partition 340. The number of partitions 340 is multiple, and the multiple partitions 340 are arranged at intervals on the transmission component 330. A placement groove 3401 is formed between two adjacent partitions 340. In this embodiment, when the battery is placed on the placement groove 3401, the battery is limited to a fixed position, which facilitates presetting the sliding frame assembly 130 at the corresponding position, so that the position where the needle puncturing component 140 provided on the sliding frame assembly 130 punctures the battery is accurate.

[0052] As Figure 1 and Figure 2 shown, in one of the embodiments, the needle puncturing component 140 includes a telescopic cylinder 141, a push plate 142 and a thimble 143. The telescopic cylinder 141 is connected to the sliding frame assembly 130, the push plate 142 is connected to the output end of the telescopic cylinder 141, and the thimble 143 is connected to the push plate 142. In this embodiment, both sides of the push plate 142 are flat, which increases the installation position and facilitates welding the thimble 143 to the push plate 142.

[0053] As Figure 2 shown, in one of the embodiments, the number of thimbles 143 is multiple, and the multiple thimbles 143 are arranged at intervals on the push plate 142. In this embodiment, the multiple thimbles 143 are sequentially and spacedly connected to the push plate 142. When the battery is punctured with a needle, the multiple thimbles 143 simultaneously puncture the same battery, enabling the battery to discharge quickly, thereby increasing the discharge efficiency of the battery.

[0054] Compared with the prior art, the present disclosure has at least the following advantages:

[0055] 1. For the above battery cell discharging device 10, when the abutting portion of the control assembly 210 abuts against the groove portion 1101, the control assembly 210 controls the transmission assembly 220 to drive the roller assembly 120 to rotate at a low speed, so that the sliding frame assembly 130 slides at a low speed on the annular track assembly 110. When the battery acupuncture assembly 140 performs acupuncture, the sliding frame assembly 130 drives the battery to slide at a low speed, so that the battery has a long continuous discharging time, and thus the battery discharges sufficiently. When the abutting portion of the control mechanism 210 abuts against the protruding portion 111, the control assembly 210 controls the transmission assembly 220 to drive the roller assembly 120 to rotate at a high speed, so that the sliding frame assembly 130 slides at a high speed on the annular track assembly 110. The sliding frame assembly 130 quickly moves along the annular track assembly 110 to the initial end of the groove portion 1101, realizing continuous discharging of multiple batteries, thereby improving the discharging efficiency of the battery cell discharging device 10 for the battery.

[0056] 2. By providing the limiting plate 320, when the acupuncture assembly 140 is pulled out from the battery, the limiting plate 320 abuts against the battery, so that the acupuncture assembly 140 can be quickly pulled out and separated from the battery smoothly, avoiding the acupuncture assembly 140 from taking the battery out of the accommodating cavity 3102.

[0057] 3. The number of the roller assembly 120, the sliding frame assembly 130, the acupuncture assembly 140 and the control mechanism 200 is multiple. Each sliding frame assembly 130 is respectively connected with a corresponding roller assembly 120, acupuncture assembly 140 and control mechanism 200. The multiple sliding frame assemblies 130 are sequentially slidably arranged on the annular track assembly 110. The multiple acupuncture assemblies 140 respectively perform acupuncture on a corresponding battery, so that multiple batteries are discharged simultaneously, improving the discharging efficiency of the battery cell discharging device 10.

[0058] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
