Technical Field

[0002] With the government's promotion of new energy sources, the lithium battery industry has developed rapidly, and the application of lithium batteries is becoming increasingly widespread. The manufacturing technology of lithium batteries is also becoming increasingly sophisticated. Lithium batteries contain harmful substances, and if discarded directly after use, they will harm the environment. Therefore, lithium batteries are usually recycled after use. For example, batteries in new energy vehicles are recycled and disassembled to collect recyclable materials.

Detailed Implementation

[0029] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figure 1As shown, an embodiment of the present invention provides a battery discharge system, comprising: an input transport line 1, a hoisting transport device 2, a battery pack distribution line 3, and a plurality of battery discharge devices 4. The hoisting transport device 2 is connected to the output end of the input transport line 1 and the input end of the battery pack distribution line 3, enabling it to hoist battery packs from the input transport line 1 onto the battery pack distribution line 3. The battery pack distribution line 3 extends to form a plurality of discharge areas, each corresponding to a battery discharge device 4. The input transport line 1 transports the battery packs to the hoisting transport device 2, the hoisting transport device 2 transports the battery packs onto the battery pack distribution line 3, the battery packs move along the battery pack distribution line 3 to the discharge areas, and the battery discharge devices 4 perform discharge operations on the batteries.

[0031] Specifically, the input transport line 1 is a common industrial transport tool, which can be a belt conveyor, chain conveyor, etc. The output end of the input transport line 1 is connected to the main body 2 of the identification device.

[0032] In this embodiment, the input transport line 1 includes an input bracket 11, a roller 12, and an input drive component. The input bracket 11 is fixed to a reliable ground surface, and the roller 12 is rotatably mounted on the input bracket 11. The input drive component is drively connected to the roller 12 and can drive the roller 12 to rotate relative to the input bracket 11. When the battery pack is placed on the roller 12, the input drive component drives the roller 12 to rotate relative to the input bracket 11, transporting the battery pack to the hoisting transport equipment 2.

[0033] like Figure 2 , Figure 3As shown, the hoisting and transporting equipment 2 includes a hoist 21, a translation mechanism 22, a lifting mechanism 23, and a clamping mechanism 24. The hoist 21 spans the output end of the input transport line 1 and the input end of the battery pack distribution line 3. The translation mechanism 22 is fixed on the hoist 21, the lifting mechanism 23 is fixed on the translation mechanism 22, and the clamping mechanism 24 is fixed to the lifting mechanism 23. The clamping mechanism 24 is used to clamp the battery pack on the input transport line 1. The lifting mechanism 23 is used to drive the clamping mechanism 24 and the battery pack clamped by the clamping mechanism 24 to move vertically. The translation mechanism 22 is used to drive the lifting mechanism 23, the clamping mechanism 24, and the battery pack clamped by the clamping mechanism 24 to move horizontally, thereby moving the battery pack from the input transport line 1 to the battery pack distribution line 3. In use, the translation mechanism 22 first moves the lifting mechanism 23 and the clamping mechanism 24 to above the battery pack on the input transport line 1. The lifting mechanism 23 then moves the clamping mechanism 24 down, and the clamping mechanism 24 clamps the battery pack. The lifting mechanism 23 then moves the clamping mechanism 24 up. The translation mechanism 22 then moves the lifting mechanism 23 and the clamping mechanism 24 to above the battery pack distribution line 3. The lifting mechanism 23 then moves the clamping mechanism 24 down, and the clamping mechanism 24 releases the battery pack, which then falls onto the battery pack distribution line 3, thus completing the hoisting of the battery pack.

[0034] In one feasible embodiment, the translation mechanism 22 includes a first-direction translation component 221 and a second-direction translation component 222. The first-direction translation component 221 is fixed to the hanger 21, and the second-direction translation component 222 is connected to the first-direction translation component 221. The first-direction translation component 221 drives the second-direction translation component 222 to move in a first direction. The second-direction translation component 222 is fixed to the lifting mechanism 23 and drives the lifting mechanism 23 to translate in a second direction. This allows the lifting mechanism 23 to move within a plane.

[0035] In some embodiments, the first direction and the second direction are perpendicular to each other.

[0036] In one feasible embodiment, the first directional translation component 221 includes a pair of first tracks 221a and a pair of first sliders 221b. The pair of first tracks 221a are fixed to the hanger 21 parallel to each other along a first direction. The pair of first sliders 221b are slidably disposed on the first tracks 221a and can slide synchronously along the first tracks 221a. The second directional translation component 222 is fixed to the pair of first sliders 221b. When the first sliders 221b slide along the first tracks 221a, the second directional translation component 222 can be moved along the first direction.

[0037] Furthermore, the second-direction translation component 222 includes a second track 222a and a second slider 222b. The second track 222a is arranged along the second direction and its two ends are fixed to a pair of first sliders 222b. The second sliders 222b are slidably disposed on the second track 222a and are capable of sliding along the second track 222a. The lifting mechanism 23 is fixed to the second slider 222b. The sliding of the second slider 222b along the second track 222a can drive the lifting mechanism 23 to move along the second direction.

[0038] In some feasible embodiments, the lifting mechanism 23 is a cylinder, which is fixed to the translation mechanism 22 in the vertical direction. The movable end of the cylinder is fixed to the clamping mechanism 24 and can extend and retract in the vertical direction, thereby driving the clamping mechanism 24 to move in the vertical direction.

[0039] In some feasible embodiments, the clamping mechanism 24 includes a fixed plate 241 and at least one pair of clamping members 242. The fixed plate 241 is fixed to the lifting mechanism 23. The clamping members 242 are arranged in pairs on the fixed plate 241, and a clamping space for clamping the battery is formed between each pair of clamping members 242.

[0040] Furthermore, the clamping component 242 includes a clamping cylinder 242a and a clamping plate 242b. The clamping cylinder 242a is fixed on the fixed plate 241, and the clamping plate 242b is fixed to the movable end of the clamping cylinder 242a. The extension and retraction of the movable end of the clamping cylinder 242a drives the clamping plate 242b to move, thereby achieving the clamping of the battery pack.

[0041] In some feasible embodiments, such as Figure 1 , Figure 4As shown, the battery pack distribution line 3 includes a main transport line 31, several transport branch lines 32, and a distribution mechanism 33. One end of the main transport line 31 is connected to the hoisting and transport equipment 2, and the other end extends to the next workstation. The transport branch lines 32 are located on one side of the main transport line 31. The distribution mechanism 33 is located inside the main transport line 31 and has a first state of retracting into the main transport line 31 and a second state of lifting the battery pack on the main transport line 31 and connecting it to the transport branch line 32. The distribution mechanism 33 can switch between the first state and the second state. When the distribution mechanism 33 is in the first state, the main transport line 31 transports the battery pack to the location of the distribution mechanism 33. The distribution mechanism 33 then switches to the second state, lifts the battery pack, and connects it to the transport branch line 32, thus transporting the battery pack onto the transport branch line 32.

[0042] Furthermore, the main transport line 31 includes a main transport support 311, a plurality of main transport rollers 312, and a main transport drive component. The main transport support 311 is fixed on a reliable ground surface. The main transport rollers 312 are rotatably mounted on the main transport support 311 at intervals. The main transport drive component is kinetically connected to the main transport rollers 312 and can drive the main transport rollers 312 to rotate relative to the main transport support 311. When the battery pack is placed on the main transport rollers 312, the main transport drive component drives the main transport rollers 312 to rotate relative to the main transport support 311, thereby transporting the battery pack.

[0043] Furthermore, the transport branch line 32 includes a branch line support 321, a plurality of branch line rollers 322, and a branch line drive component. The branch line support 321 is fixed on a reliable ground surface. The branch line rollers 322 are rotatably mounted on the branch line support 321 at intervals. The branch line drive component is kinetically connected to the branch line rollers 322, enabling the branch line rollers 322 to rotate relative to the branch line support 321. When the battery pack is placed on the branch line rollers 322, the branch line drive component drives the branch line rollers 322 to rotate relative to the branch line support 321, thus transporting the battery pack. The end of the transport branch line 32 away from the main transport line 31 forms the discharge area.

[0044] Understandably, the height of the branch support 321 is higher than the height of the main transport support 311.

[0045] Furthermore, such as Figure 5As shown, the distributing mechanism 33 includes a lifting cylinder 331, a carrier plate 332, and at least two support frames 333. Each support frame 333 is equipped with a belt conveyor line 334. The lifting cylinder 331 and the carrier plate 332 are located below the main conveyor roller 312. The movable end of the lifting cylinder 331 is fixed to the carrier plate 332. The movable end of the lifting cylinder 331 can drive the carrier plate 332 to rise and fall in the vertical direction. The support frames 333 are fixed to the carrier plate 332 at intervals and correspond to the gap between the main conveyor roller 312. When the movable end of the lifting cylinder 331 is extended to its maximum state, the support frame 333 extends out from the gap between the main conveyor rollers 312, and the belt conveyor line 334 corresponds to the conveyor branch line 32.

[0046] When the battery pack is transported along the main transport line 31 to the position corresponding to the transport branch line 32, the lifting cylinder 331 lifts it up, and the support frame 333 extends from the gap between the main transport rollers 312, lifting the battery pack. The belt conveyor 334 corresponds to the transport branch line 32 and transports the battery pack onto the transport branch line 32. This achieves the transfer of the battery pack from the main transport line 31 to the transport branch line 32.

[0047] Specifically, the battery pack distribution line 3 also includes a coordination drive mechanism 34, which is electrically connected to the main transport line 31, the transport branch line 32 and the distribution mechanism 33, and is used to coordinate and schedule the main transport line 31, the transport branch line 32 and the distribution mechanism 33.

[0048] Furthermore, the coordinated drive mechanism 34 includes a first sensor 341, a second sensor 342, a pressure sensor, and a processing unit. The first sensor 341 is fixed at the position corresponding to the main transport line 31 and the transport branch line 32, and is used to sense whether the battery pack on the main transport line 31 passes the position corresponding to the transport branch line 32. The second sensor 342 is fixed on the transport branch line 32 and located in the discharge area, and is used to sense whether the battery pack on the transport branch line 32 has reached the discharge area. The pressure sensor is embedded in the distribution mechanism 33 and is used to sense whether there is a battery pack on the distribution mechanism 33. The processing unit is electrically connected to the first sensor 341, the second sensor 342, the pressure sensor, the main transport line 31, the transport branch line 32, and the distribution mechanism 33. The processing unit is used to schedule the main transport line 31, the transport branch line 32, and the distribution mechanism 33 according to the signals from the first sensor 341, the second sensor 342, and the pressure sensor.

[0049] When the first sensor 341 generates a signal, indicating that the battery pack on the main transport line 31 has passed the position corresponding to the transport branch line 32, the processing unit drives the main transport line 31 to stop, the lifting cylinder 331 lifts, and the support frame 333 extends from the gap between the main transport rollers 312 to lift the battery pack. The belt transport line 334 corresponds to the transport branch line 32 and transports the battery pack to the transport branch line 32. When the pressure sensor generates a signal, it indicates that the belt transport line 334 is in contact with the battery pack. When the signal of the pressure sensor disappears, it indicates that the battery pack on the belt transport line 334 has been transported to the transport branch line 32. At this time, the processing unit drives the movable end of the lifting cylinder 331 to descend, the belt transport line 334 stops working, and the transport branch line 32 starts working. When the second sensor 342 generates a signal, it indicates that the battery pack has moved to the discharge area. The processing unit drives the transport branch line 32 to stop working, and the battery discharge device 4 performs a discharge operation on the battery.

[0050] Understandably, once the battery pack has finished discharging, the transport branch line 32 can transport the battery pack to the main transport line 31, the distribution mechanism 33 can transport the battery pack back to the main transport line 31, and the main transport line 31 can send the discharged battery pack to the next workstation.

[0051] Specifically, the battery discharge device 4 is used to discharge the battery pack. It can consume the power in the battery pack and record the discharge curve of the battery pack. The discharge curve of the battery pack is matched with the discharge curves of different types of batteries stored inside the battery pack to determine the type of battery in the battery pack and record it for subsequent targeted disassembly and recycling.

[0052] The beneficial effects of this invention are as follows: This invention includes an input transport line, a battery pack distribution line, a hoisting transport device, and a battery discharge device. The input transport line transports the battery packs to the hoisting transport device, which then transports the battery packs to the battery pack distribution line. The battery packs move along the distribution line to the discharge area, where the battery discharge device discharges the battery packs within the discharge area. This replaces manual loading and unloading of batteries, reducing the workload of workers and improving work efficiency.

[0053] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
