For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 and Figure 2 As shown, an embodiment of the unpacking device according to the present application includes an unpacking chamber 10, a cutting structure 30, a fixing structure 40 and a blanking structure 90. The side of the unpacking chamber 10 has an inlet and an outlet, and both the inlet and the outlet are provided with a sealing door 20 that can be opened and closed. The bottom of the unpacking chamber 10 is provided with a discharge port 11. The cutting structure 30 is arranged at the bottom of the unpacking chamber 10. The fixing structure 40 is movably arranged in the unpacking chamber 10, and the fixing structure 40 has a fixing position for fixing the ton bag 1 and a loosening position for loosening the ton bag 1. The blanking structure 90 is arranged at the lower side of the discharge port 11.

[0026] Using the technical solution of this embodiment, when the ton bag 1 needs to be unpacked, the ton bag 1 enters from the entrance of the unpacking chamber 10, and the fixed structure 40 moves to a fixed position to fix the ton bag 1 in the unpacking chamber 10. Then the sealed doors 20 at the entrance and exit of the unpacking chamber 10 are closed, so that the ton bag 1 is in a closed environment. At this time, the cutting structure 30 cuts the bottom of the ton bag 1, and the material in the ton bag 1 falls from the discharge port 11 of the unpacking chamber 10 into the blanking structure 90, completing the unpacking. After the unpacking is completed, the sealed doors at the entrance and exit of the unpacking chamber 10 are opened, and the unpacked ton bag 1 is sent out from the outlet of the unpacking chamber 10, and the unpacked ton bag 1 enters the unpacking chamber 10. The above structure realizes the automated unpacking of the ton bag 1, which greatly improves the efficiency compared to manual unpacking. Therefore, the technical solution of this embodiment solves the defect of low efficiency of manual unpacking of ton bags in the battery production process in the prior art.

[0027] like Figure 2 As shown, further, the unpacking chamber 10 is generally a box-like structure, which includes a bottom wall, a side wall and a top wall, and encloses a space. The inlet and the outlet of the unpacking chamber 10 are respectively arranged on two opposite side walls of the unpacking chamber 10, and the unpacked ton bag 1 can enter the unpacking chamber 10 through the inlet for unpacking, and the unpacked ton bag 1 can leave the unpacking chamber 10 through the outlet.

[0028] Furthermore, the entrance and exit of the unpacking chamber 10 are both provided with sealing doors 20, which may be rolling doors, sliding doors, telescopic doors, etc. When unpacking, both sealing doors 20 are in a closed state, so that the unpacking chamber 10 is in a closed state, to prevent the powder from affecting the external environment during unpacking, and at the same time, to prevent impurities from the external environment from entering the unpacking chamber 10 and contaminating the powder. When the ton bag 1 needs to circulate in the unpacking chamber 10 (unpacked ton bags 1 flow into the unpacking chamber 10, or unpacked empty ton bags 1 flow out of the unpacking chamber 10), the two sealing doors 20 are in an open state.

[0029] from Figure 2 It can be seen that a discharge port 11 is provided on the bottom wall of the unpacking chamber 10, and after the ton bag 1 is unpacked, the material inside is discharged from the discharge port 11. A blanking structure 90 is provided at the lower side of the unpacking chamber 10. In this embodiment, the powder material in the ton bag 1 is transported to the homogenizing device through the blanking structure 90 after unpacking, so as to be pulped.

[0030] Optionally, the material dropping structure 90 may include a hopper and a feeding pipe, wherein the upper end of the hopper is connected to the discharge port 11, and the lower end of the hopper is connected to the feeding pipe. After unpacking, the powder in the ton bag 1 first falls into the hopper for collection, and then is transported through the feeding pipe.

[0031] Optionally, a filter screen may be provided at the discharge port 11 to filter impurities in the powder in the ton bag 1 .

[0032] Optionally, the blanking structure 90 may be provided with a negative pressure structure, which can suck the powder dispersed in the unpacking chamber 10 into the hopper, thereby reducing the waste of powder.

[0033] Optionally, the material bag of the ton bag 1 may be an aluminum-plastic film material bag to prevent impurities such as debris from being generated when the cutting structure 30 cuts the bottom of the ton bag 1 and contaminating the powder.

[0034] like Figure 2 As shown, a fixing structure 40 is provided in the unpacking chamber 10, and the fixing structure 40 can move between a fixing position and a releasing position. It should be noted that Figure 2 The dashed line shown is a schematic diagram of the fixing structure 40 being in a loosened position. Figure 2 The solid line shown is a schematic diagram of the fixing structure 40 being in a fixed position. Specifically, the fixing structure 40 is initially in a loose position. When the ton bag 1 enters the unpacking chamber 10, the fixing structure 40 moves to a fixed position and fixes the ton bag 1 in the unpacking chamber 10. After the ton bag 1 is fixed, the cutting structure 30 cuts open the bottom of the ton bag 1, and the powder in the ton bag 1 falls into the blanking structure 90 through the discharge port 11, thereby completing the unpacking. After the unpacking is completed, the fixing structure 40 moves from the fixed position to the loose position, so that the empty ton bag 1 can be transported out of the unpacking chamber 10.

[0035] Optionally, the cutting structure 30 includes a cutting knife having a blade. In the present embodiment, the cutting knife is rotatably arranged at the bottom of the unpacking chamber 10. When the cutting knife rotates, the blade can pass through the bottom of the ton bag 1, thereby achieving the effect of cutting the ton bag 1 apart for unpacking.

[0036] In some embodiments not shown, the cutting knife may also be movably arranged at the bottom of the unpacking chamber 10 , and the movement of the cutting knife may be horizontal movement or vertical movement, as long as the ton bag 1 can be cut.

[0037] In some embodiments not shown, the fixed structure 40 can move in the vertical direction. When the powder in the ton bag 1 is about to be discharged, the fixed structure 40 moves upward to lift the ton bag 1, and the ton bag 1 is suspended in the air to reduce the residual powder in the ton bag 1.

[0038] like Figure 2 As shown, in the technical solution of this embodiment, the fixing structure 40 includes a clamping arm, one end of which is rotatably arranged in the unpacking chamber 10, and the other end of the clamping arm is suitable for cooperating with the ton bag 1, and the clamping arm swings between a fixed position and a released position.

[0039] Specifically, from Figure 2It can be seen that when the clamp arm swings upward, the clamp arm can swing to a loose position, at which time the clamp arm does not cooperate with the ton bag 1, and the ton bag 1 can pass under the clamp arm. When the clamp arm swings downward, the clamp arm can swing to a fixed position, at which time the end of the clamp arm will be stuck on the side wall of the ton bag 1 and fix the ton bag 1 in the unpacking chamber 10.

[0040] Optionally, the swing of the clamping arm can be driven and controlled by a mechanism such as a motor.

[0041] Furthermore, the clamping arm includes a straight section and an arc section, one end of the straight section is rotatably connected to the unpacking chamber 10, and the other end of the straight section is connected to the arc section, and the end of the arc section is suitable for matching with the ton bag 1. Figure 2 It can be seen that when the clamp arm swings to the release position, the position of the straight section is vertical, and when the clamp arm swings to the fixed position, the position of the straight section is horizontal.

[0042] Of course, the fixing structure 40 may also adopt structures such as claws, clamping claws, etc., and is not limited to the above-mentioned clamping arms, as long as the ton bag 1 can be fixed in the unpacking chamber 10.

[0043] like Figure 2 As shown, in the technical solution of this embodiment, the end of the clamp arm is pointed, and an air blowing pipe 41 is provided on the clamp arm, and the air blowing pipe 41 forms an air blowing port 42 at the end of the clamp arm.

[0044] Specifically, since the end of the clamp arm is pointed, when the clamp arm swings to a fixed position, the clamp arm can penetrate into the ton bag 1, that is, the blowing port 42 enters into the ton bag 1. The blowing pipe 41 can be connected to an external positive pressure blowing device. When unpacking, the blowing pipe 41 is passed with purge gas, and the purge gas can be blown out from the blowing port 42, thereby purge the inside of the ton bag 1, blow the residual powder and discharge it from the discharge port 11, and reduce the residual powder.

[0045] Optionally, the clamp arm is a hollow tubular structure, and the end opening of the clamp arm forms an air blowing port 42. That is, the clamp arm forms the above-mentioned air blowing pipe 41, so the clamp arm not only plays a role in fixing the ton bag 1, but also plays a role in blowing the ton bag 1 when unpacking.

[0046] In some embodiments not shown, an air blowing pipe 41 may also be additionally fixedly installed on the outer surface of the clamp arm, that is, the clamp arm itself does not form an air blowing pipe.

[0047] In some embodiments not shown, after the fixed structure 40 moves upward to suspend the ton bag 1 in the air, the ton bag 1 is blown through the blowing port 42 of the clamping arm to cooperate with the residual powder in the ton bag 1 so that the residual powder in the ton bag 1 can be discharged more thoroughly.

[0048] Optionally, a plurality of clamping arms are provided, and the plurality of clamping arms are arranged at intervals around the outside of the ton bag 1 . The plurality of clamping arms can clamp the ton bag 1 in multiple directions, so that the ton bag 1 is fixed more stably in the unpacking chamber 10 .

[0049] In this embodiment, two clamping arms are provided, and the two clamping arms are respectively located on both sides of the ton bag 1 . The two clamping arms swing synchronously to a fixed position or a released position, and the two clamping arms can clamp both sides of the ton bag 1 .

[0050] In some embodiments not shown, the number of the clamping arms may be more than two.

[0051] Optionally, the two clamp arms in this embodiment are both hollow tubular structures, that is, the two clamp arms both form the blowing pipe 41. Of course, it is also a feasible implementation to form the blowing pipe 41 on only one clamp arm.

[0052] like Figure 2 As shown, in the technical solution of this embodiment, a blocking structure 50 is provided on the side wall of the unpacking chamber 10, and when the clamping arm is swung toward the release position and pulled out from the ton bag 1, the blocking structure 50 is suitable for fixing the ton bag 1.

[0053] Specifically, after unpacking is completed, the clamp arm needs to be pulled out of the ton bag 1. Since there is friction between the clamp arm and the ton bag 1, and the empty ton bag 1 is light in weight, the clamp arm can easily lift up the empty ton bag 1 when it swings upward to the release position. In this embodiment, a blocking structure 50 is provided. When the clamp arm swings upward to the release position, the blocking structure 50 can block the ton bag 1 from above, so that the clamp arm can be smoothly pulled out of the ton bag 1.

[0054] Optionally, the blocking structure 50 may include a block, which is disposed on the inner wall of the unpacking chamber 10. A notch may be disposed on the block, and the clamping arm may pass through the notch when swinging, thereby not interfering with the block.

[0055] Optionally, two blocking structures 50 are provided, and the two blocking structures 50 are respectively arranged on two opposite inner side walls of the unpacking chamber 10 , and the two blocking structures 50 are respectively matched with two clamping arms.

[0056] like Figure 2 As shown, in the technical solution of this embodiment, a dust extraction port 12 is provided on the unpacking chamber 10. Specifically, the dust extraction port 12 can be connected to an external negative pressure device to generate negative pressure at the dust extraction port 12, and the dust in the unpacking chamber 10 after unpacking is extracted, thereby reducing the impact on the external environment.

[0057] like Figure 1 As shown, in the technical solution of this embodiment, the unpacking device further includes a cleaning chamber 60 , the outlet of the cleaning chamber 60 is connected to the inlet of the unpacking chamber 10 , and an air blowing port is provided in the cleaning chamber 60 .

[0058] Specifically, before unpacking, the ton bag 1 needs to enter the cleaning room 60 for surface cleaning. In the cleaning room 60, the air outlet can blow out purge gas to remove debris on the surface of the ton bag 1, preventing the debris on the surface of the ton bag 1 from being transferred into the blanking structure 90 in the unpacking room, thereby avoiding affecting the subsequent pulping quality.

[0059] Optionally, the outlet of the cleaning chamber 60 and the inlet of the unpacking chamber 10 may be connected via a passage, or may be arranged adjacent to each other.

[0060] like Figure 1 As shown, in the technical solution of this embodiment, a circulation structure 70 is provided in both the unpacking room 10 and the cleaning room 60. Specifically, the ton bag 1 can enter the cleaning room 60 through the outside, and after the ton bag 1 is cleaned in the cleaning room 60, the ton bag 1 is transferred to the unpacking room 10 through the circulation structure 70. After the ton bag 1 is unpacked in the unpacking room 10, the empty ton bag 1 is transferred out of the unpacking room 10 through the circulation structure 70, thereby realizing the automatic unpacking of the whole process.

[0061] Optionally, the circulation structure 70 may be a circulation belt, a driving wheel, a robot, etc.

[0062] like Figure 1 As shown, in the technical solution of this embodiment, the unpacking device also includes a bag receiving chamber 80, the inlet of the bag receiving chamber 80 is connected to the outlet of the unpacking chamber 10, and the bag receiving chamber 80 is suitable for collecting the unpacked ton bags 1.

[0063] Specifically, after the ton bags 1 are unpacked in the unpacking chamber 10 , the empty ton bags 1 are transferred to the bag collecting chamber 80 through the transfer structure 70 , and the empty ton bags 1 are collected.

[0064] Optionally, the outlet of the unpacking chamber 10 and the inlet of the bag receiving chamber 80 may be connected via a passage, or may be arranged adjacent to each other.

[0065] like Figure 1 As shown, in the technical solution of this embodiment, a receiving box 81 and a pressing plate 82 are provided in the bag receiving chamber 80 , and the pressing plate 82 is movably provided above the receiving box 81 .

[0066] Specifically, the storage box 81 is arranged at the bottom of the bag receiving chamber 80, and the entrance of the bag receiving chamber 80 is arranged above the storage box 81. Therefore, after the empty ton bag 1 enters the bag receiving chamber 80, it falls into the storage box 81. The pressing plate 82 can be driven by the driving cylinder and move in the up and down direction. When the storage box 81 is filled with empty ton bags 1, the pressing plate 82 moves downward and compacts the empty ton bags 1, and then the pressing plate 82 rises, thereby reducing the number of replacement times of the storage box 81.

[0067] Optionally, the storage box 81 can be configured as a pull-out structure (similar to the form of a drawer). When the storage box 81 is filled with compressed empty ton bags 1, the operator pulls out the storage box 81 and takes out the empty ton bags 1, and then pushes the storage box 81 back.

[0068] According to the unpacking experiment conducted by the applicant, in the prior art, manual unpacking takes 12 minutes to complete one unpacking operation, while the unpacking device of this embodiment can shorten one unpacking operation to less than 4 minutes, greatly improving the unpacking efficiency and realizing the automation of unpacking.

[0069] The present application also provides a battery production line, which includes the above-mentioned unpacking device.

[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
