[0050] In order to solve the technical problem of dust emission and dust leakage during the operation of automatic unpacking devices in the prior art, the present application provides an automatic unpacking device with good sealing performance. The device can effectively reduce dust emission and dust leakage while realizing automatic unpacking and unloading. The materials or packaging bags referred to in this application refer to materials packaged and stored in packaging bags, such as lithium battery packs.

[0051] The present application embodiment provides an automatic unpacking device, such as Figure 1 As shown, the automatic unpacking device includes a housing 10, a material conveying mechanism 20, a powder collection hopper 40, a bag cutting mechanism, a bag clamping and transporting mechanism, and a dust removal mechanism 70. The housing 10 is provided with a material inlet and a bag outlet. The material inlet is used to deliver material into the housing 10, and the bag outlet is used to discharge empty bags. The material conveying mechanism 20 extends from the material inlet into the housing 10 and is capable of conveying bagged material into the housing 10. The material conveying mechanism 20 can be a conveyor belt unit or a roller conveyor unit, which is not specifically limited in this application.

[0052] The bag clamping and transferring mechanism is arranged at the end of the material conveying mechanism 20, and is used to receive the packaging bag material conveyed by the material conveying mechanism 20 and transport it to the bag cutting mechanism for bag cutting, and then unload the powder in the packaging bag into the powder collecting hopper 40 below the bag cutting mechanism. The bag unloading and transferring mechanism is also used to transfer the empty packaging bag to the packaging bag outlet for unloading and return to the end of the material conveying mechanism 20 to receive the material; the dust removal mechanism 70 is arranged on the top of the box body 10 and is used to absorb and remove the dust scattered in the box body 10. The dust removal mechanism 70 can usually adopt a centralized dust collector, specifically a bag dust collector, etc. The dust collector structure and dust removal principle can refer to the existing technology.

[0053] The operation process of the above-mentioned automatic unpacking device is as follows:

[0054] The packaging bag materials, such as lithium battery packs, are delivered into the box body 10 by the material conveying mechanism 20 at the material inlet. The bag clamping and transferring mechanism receives the packaging bag materials at the end of the material conveying mechanism 20 and transfers them to the bag cutting mechanism above the powder collecting hopper 40 for cutting. After cutting, an opening is formed to discharge the powder into the powder collecting hopper 40; the bag clamping and transferring mechanism transfers the empty packaging bag to the packaging bag outlet for unloading and returns to the end of the material conveying mechanism 20 to receive the material; the bag clamping and transferring mechanism transfers the packaging bag, the bag cutting mechanism cuts the packaging bag, and the powder collecting hopper 40 receives and collects the powder, all of which are carried out in the box body 10. The sealing performance of the entire device is good, and the raised dust can be absorbed and removed by the dust removal mechanism 70 on the top of the box body 10, thereby effectively avoiding dust emission and dust leakage.

[0055] In some embodiments, the material inlet is equipped with a first sealed door 11 that can be opened and closed automatically. The first sealed door 11 can be a rolling shutter lift door. When the bagged material is conveyed into the box 10 through the material inlet, the first sealed door 11 rises to open the material inlet. When the bagged material is delivered into the box 10 for bag cutting and powder discharge, the first sealed door 11 partially closes, providing a certain degree of shielding from the material inlet and reducing dust dissipation and leakage to the outside.

[0056] Furthermore, a material identification mechanism 12 is provided at the material inlet, positioned toward the material conveying mechanism 20. This mechanism is connected to the first sealed door 11. Upon identifying corresponding packaging bag material being conveyed toward the material inlet, the mechanism controls the first sealed door 11 to open the material inlet, allowing the material to be fed into the housing 10. After the packaging bag material is delivered into the housing 10, the first sealed door 11 lowers, partially closing the material inlet. The material identification mechanism 12 can employ a barcode scanning mechanism to identify the material by scanning the barcode information on the packaging bag material. Alternatively, the material identification mechanism can employ an image recognition mechanism to identify the incoming material through image analysis. For details, reference can be made to the prior art.

[0057] Correspondingly, the packaging bag outlet is provided with a second sealed door body 13 that can be opened and closed automatically. When the material conveying mechanism 20 and the bag clamping and transferring mechanism are transferring the packaging bag materials, the bag cutting mechanism is cutting the packaging bag materials, and the packaging bag materials are unloading after the bags are cut, the second sealed door body 13 closes the packaging bag outlet, which also serves as a way to reduce the spread of dust to the outside. When the packaging bag materials after bag cutting have completed unloading into the powder collection hopper 40 and the empty packaging bags are sent to the packaging bag outlet by the bag clamping and transferring mechanism, the second sealed door body 13 opens the packaging bag outlet to unload the empty packaging bags. An identification control mechanism for identifying the bag clamping and transferring mechanism can be provided at the second sealed door body 13, and the opening or closing of the second sealed door body 13 is controlled by the identification control mechanism. The second sealed door body 13 can also be associated with the first sealed door body 11, and open for a certain period of time and then close after the first sealed door body 11 is closed for a preset time.

[0058] Furthermore, an empty bag collection box 60 is located below the bag outlet to collect the empty bags after they are cut and unloaded. The empty bag packaging box can be mounted on an automated guided vehicle 61, or AGV. When the empty bag packaging box is full, the AGV 61 transports the empty bag packaging box to a designated recycling location for processing.

[0059] In a preferred embodiment provided herein, an ultrasonic bag cutting mechanism can be employed to prevent debris and heat generation during bag cutting. The bag cutting mechanism specifically includes a cutter moving cylinder 30 and an ultrasonic cutter 31. The cutter moving cylinder 30 is positioned along the material conveying direction of the material conveying mechanism 20 and the bag clamping and transfer mechanism. The ultrasonic cutter 31 is connected to the cutter moving cylinder 30. The cutter moving cylinder 30 drives the ultrasonic cutter 31 to reciprocate along the material conveying direction of the packaging bag to cut the bag.

[0060] In some embodiments, the bag clamping transfer mechanism includes a transmission guide assembly 50, a drive motor 51, a transfer frame 52 and a transfer bracket 54. The transmission guide assembly 50 is extended along the direction from the material inlet to the packaging bag outlet, and the transmission guide assembly 50 can be in the form of a transmission structure such as a chain and a guide rail. The transfer frame 52 is connected to the transmission guide assembly 50 and reciprocates along the extension direction of the transmission guide assembly 50 under the drive of the transmission guide assembly 50. For example, the transfer frame 52 can be provided with a tooth portion that cooperates with the chain, and the transfer frame 52 is slidably connected to the guide rail, and the reciprocating rotation of the chain drives the transfer frame 52 to reciprocate along the guide rail. The drive motor 51 is fixed to the top of the box 10 and is connected to the transmission guide assembly 50. By driving the transmission guide assembly 50 to operate, the transfer frame 52 is driven to reciprocate. The transfer bracket 54 is connected below the transfer frame 52. It has a receiving slot that receives the bagged material at the end of the material conveyor mechanism 20 along the conveying direction of the bagged material. A cutting slot is provided at the bottom of the transfer bracket 54, extending through the slot. The slot is positioned along the conveying direction of the bagged material, allowing the ultrasonic cutter 31 to penetrate through the slot and cut the bagged material. A lifting mechanism can be installed between the transfer bracket 54 and the transfer frame 52 as needed to adjust the bagged material to the appropriate height for cutting, unloading, and unloading empty bags.

[0061] like Figures 1 to 6 As shown, in the first state, the transfer bracket 54 of the bag clamping transfer mechanism receives the packaging bag at the end of the material conveying mechanism 20 through the bracket groove; in the second state, the bag clamping transfer mechanism drives the packaging bag to move and descend to the cutting position; in the third and fourth states, the cutter moving cylinder 30 drives the ultrasonic cutter 31 to move back and forth through the cutting groove to cut the packaging bag in the bracket groove, and the dust in the packaging bag after cutting falls into the powder collecting hopper 40; in the fifth state, the bag clamping transfer mechanism transfers the empty packaging bag to above the packaging bag outlet; in the sixth state, the second sealing door body 13 is opened, and the bag clamping transfer mechanism drives the transfer bracket 54 to descend and unload the empty packaging bag into the empty bag packaging box.

[0062] In order to realize the bag-holding transfer mechanism to carry the bag materials and unload them, Figures 7 to 10As shown, the bag clamping and transporting mechanism includes a pair of first brackets 541, a folding cylinder 542, a bag locking cylinder 543 and a bag locking hook 544. The first bracket 541 is concave, and a pair of first brackets 541 are arranged opposite to each other with a groove opening. The pair of first brackets 541 are hinged through the upper side edges, and the lower side edges of the pair of first brackets 541 are arranged relative to each other at a preset interval, and the preset gap forms a cutting groove. The bracket groove is formed between the upper side edges and the lower side edges of the pair of first brackets 541. The folding cylinder 542 is connected to the hinge at the upper side edges of the pair of first brackets 541, and the first bracket 541 is driven to switch between the open state and the folded state by the telescopic movement of the folding cylinder 542. The folded state is as shown in FIG. Figure 7 As shown, the lower side of the first bracket 541 is in a horizontal state, used to carry the packaging bag material. Figures 8 to 10 As shown, it is used to unload powder and empty packaging bags; in order to fully shake off the powder, the folding cylinder 542 can be used to reciprocate and extend to drive the first bracket 541 to repeatedly open and close.

[0063] The bag locking cylinder 543 is connected to the first bracket 541, and the middle part of the bag locking hook 544 is flipped and connected to the first bracket 541. The first end of the bag locking hook 544 is hinged to the bag locking cylinder 543, and the bag locking hook 544 is flipped relative to the first bracket 541 by telescopic driving. The second end of the bag locking hook 544 is a tip extending toward the lower side of the first bracket 541. Driven by the bag locking cylinder 543, the second end of the bag locking hook 544 can rotate toward or away from the lower side of the first bracket 541. When the second end of the bag locking hook 544 rotates toward the lower side of the first bracket 541, the packaging bag carried on the lower side of the first bracket 541 is fastened and fixed, making it easier for the ultrasonic cutting knife 31 to cut the packaging bag, such as Figure 8 The state of the first bracket 541 opening to unload the powder is shown as follows. Figure 9 When the second end of the bag locking hook 544 is rotated away from the lower side of the first bracket 541, the second end of the bag locking hook 544 is separated from the packaging bag, making it easier to remove the packaging bag after cutting and unloading. Figure 10 shown.

[0064] In order to prevent the empty packaging bag from being hooked on the bag locking hook 544, each group of first brackets 541 is also fixedly connected to a bag unloading bracket 545. The bag unloading bracket 545 is located in the bracket groove and extends to a preset height above the lower side of the first bracket 541. When the first bracket 541 is flipped open and the bag locking hook 544 is rotated away from the lower side of the first bracket 541, the bag unloading bracket 545 can stop the empty packaging bag hooked on the second end of the bag unloading hook so that the empty packaging bag can be removed from the second end of the bag locking hook 544. Figure 9 and Figure 10 shown.

[0065] At the same time, in order to facilitate the driving of the transfer bracket 54 to rise and fall, the transfer bracket 54 and the transfer frame 52 are connected by a lifting cylinder 53. The lifting cylinder 53 is symmetrically arranged around the folding cylinder 542 and is hinged to the edge of the transfer bracket to ensure that when the folding cylinder 542 extends and presses down the hinge of a pair of first brackets 541, the first bracket 541 can be flipped and opened.
