Description

TECHNICAL FIELD

[0001] The utility model relates to the field of waste battery processing technology, especially to a battery module recycling and packing system. BACKGROUND

[0002] With the rapid development of new energy vehicles, the demand for vehicle power battery modules has increased significantly. However, after the service life of the power battery module expires, it still contains a large amount of valuable materials and potential environmental hazards inside, so the recycling and reuse of the power battery module is particularly important. During the recycling process of the power battery module, safe and efficient transportation and storage are key links, so a special packing device is needed to standardize the processing of the recycled power battery module to ensure its safety, stability and economy during transportation and storage.

[0003] Currently, the packing devices for power battery modules on the market mainly focus on packing new batteries. These devices aim to protect the integrity of the batteries during transportation and storage, preventing damage caused by vibration, collision or external environmental factors. The technical solution includes: automatically sorting new batteries through a conveyor belt and a mechanical arm, and stacking them in the specified direction and position.

[0041] With the rapid development of new energy vehicles, the demand for vehicle power battery modules has increased significantly. However, after the service life of the power battery module expires, because there are still a large amount of valuable materials and potential environmental hazards inside, the recycling and reuse of the power battery module is particularly important. In the recycling process of the power battery module, safe and efficient transportation and storage are key links, so a special packaging device is needed to standardize the treatment of the recycled power battery module to ensure its safety, stability and economy during transportation and storage.

[0042] At present, the packaging devices for power battery modules on the market mainly focus on the packaging of new batteries. These devices aim to protect the integrity of the batteries during transportation and storage, prevent damage caused by vibration, collision or external environmental factors. Its technical scheme includes: through the conveying belt and mechanical arm, the new battery is automatically sorted and stacked according to the specified direction and position. And add buffer materials (such as foam, air cushion, etc.) between the batteries to absorb external impact. Finally, the packaged battery is packaged by heat shrink film or other sealing methods to prevent moisture, dust or other environmental factors from entering.

[0043] Although the above packaging device for new power battery modules performs well in the transportation and storage of new batteries, it has the following shortcomings when dealing with waste power battery modules: the appearance, shape and state of waste power battery modules vary greatly due to different use conditions, and existing devices are mostly standardized design, which is difficult to adapt to the diversity of waste batteries. Waste battery modules may have the risk of swelling, liquid leakage or short circuit, and existing packaging devices lack targeted design, which may not effectively reduce these hidden dangers, and when dealing with waste battery modules, existing devices may need additional human intervention to adapt to non-standard battery module shapes, reducing overall efficiency.

[0044] The utility model provides a battery module recycling and packing system for solving the above problems.

[0045] Please refer to Figures 1 to 4 In an embodiment of the utility model, the battery module recycling and packing system is mainly used for packing and classification in the recycling process of new energy vehicle batteries. After recycling, vehicle batteries need to be classified first, for example, classifying batteries without direct safety risks with good appearance or slight deformation and damage or not exceeding the safety limit conditions specified by the manufacturer into one category, then classifying battery modules that visually detect liquid leakage, deformation, serious damage or human disassembly marks exceeding the safety limit conditions specified by the manufacturer into another category, after classification, the battery modules need to be packed, then classified and stored and transported according to the above different categories, so as to minimize the risk in the transportation process. Specifically, the battery module recycling and packing system mainly includes a storage box structure and a packing structure, the storage box structure is set to two types according to the above classification of battery modules, during the operation of the whole system, first, the battery modules need to be classified manually or with the help of corresponding equipment, before placing the battery modules on the rotating part 4 for film packing, first, install the corner mounting part 1 at each corner of the battery module, the corner mounting part 1 has a certain buffering property, installing it at each corner position of the battery module can effectively prevent hard contact between the battery module and the storage box structure 3 during transportation, thereby increasing the risk of transportation. Specifically, after installing a plurality of corner mounting parts 1, place them together with the battery module on the rotating part 4, then connect one end of the film mounting part 6 to the battery module, the rotating part 4 moves, which will wrap the packing film on the outer peripheral wall, thereby forming a whole packing structure between the plurality of corner mounting parts 1 and the battery module, in this process, in order to ensure the stability of the battery module during rotation of the rotating part 4, the limiting part 5 needs to be in contact with the upper end of the battery module, so that the battery module maintains a stable horizontal state during rotation.

[0046] Among them, because the battery module in the scheme is a conventional battery structure, it is generally set as a square structure, so the corresponding corner mounting piece 1 used in the embodiment is also set as a three-sided protection structure. Specifically, each of the corner pieces includes three mutually connected buffer plates 311, and the corresponding end faces of the three buffer plates 311 form an abutting cavity, and the corner of the battery module is mounted inside the abutting cavity. In actual production, the corner mounting piece 1 needs to be made of insulating material, for example, set as rubber material, which also has a certain buffering effect, which can improve the safety during transportation to a certain extent. It should be noted that the abutting cavity formed by the three buffer plates 311 can be set to be slightly smaller than the size of the battery module corner, so that during installation, a certain connection state can be formed between the two by extrusion, and when the combined structure of the two is placed on the rotating piece 4, it can be more convenient.

[0047] Of course, the specific shape of the corner mounting piece 1 is also set according to the specific shape of the battery module corner, and the specific number can be increased or decreased according to the actual situation.

[0048] In the embodiment, the rotating piece 4 is specifically set as a motor driving structure 63, which mainly includes a first motor 41 and a receiving plate 42. Among them, the first motor 41 is installed on the base 2, and the center of the receiving plate 42 is connected with the output shaft of the first motor 41. During the actual film packaging process, the first motor 41 drives the battery module on the receiving plate 42 to rotate synchronously, and during the rotation, the film piece 6 continuously releases the packaging film synchronously, so as to complete the packaging work of the battery module itself during the rotation of the battery module. A flange portion 421 is arranged on the upper end surface of the receiving plate 42, which can limit the horizontal end of the battery module, cooperate with the limiting portion 5, and as much as possible to improve the stability of the battery module during movement. It can be thought that the driving device in the rotating piece 4 can also be set as a cylinder connecting rod structure and the like to complete the above actions, and intersected with other driving pieces, except for specific use scenes or production material restrictions, the direct drive method in the embodiment is more convenient.

[0049] Because the battery module has a certain weight, it is certainly not enough to support it only by the first motor 41, in order to protect the first motor 41 and improve the stability of the whole structure during operation, a mounting frame 43 is arranged on the base 2, a plane bearing 44 is arranged on the mounting frame 43, the supporting plate 42 is supported by the plane bearing 44, which can effectively reduce the pressure of the first motor 41, and the structure is more reasonable, and the output shaft of the first motor 41 can be rotatably connected to the upper end surface of the mounting frame 43, or a hole structure corresponding to the output shaft of the first motor 41 can be formed on the mounting frame 43.

[0050] The limiting part 5 specifically includes a mounting rod 51 and a movable pressing part 52, the mounting vertical rod 511 in the mounting rod 51 is connected with the base 2, and a mounting horizontal rod 512 is connected to the end thereof and rotatably connected therebetween, so that the movable pressing part 52 on the mounting horizontal rod 512 can be rotated to one side of the battery module during the feeding and discharging of the battery module, thereby facilitating the feeding and discharging of the battery module. Before the battery module on the supporting plate 42 is packed, the mounting horizontal rod 512 is rotated, the disc part 522 is placed directly above the battery module, then the push rod 521 works and drives the disc part 522 to move downward, so that the lower end surface of the disc part 522 is in contact with the upper end surface of the battery module and maintains a certain contact force, and the battery module drives the disc part 522 to rotate synchronously at the end of the push rod 521 during rotation.

[0051] Considering that the battery module to be packed has a certain vertical height, in order to form a good wrapping packing effect on the whole vertical height of the battery module, in the embodiment, the film covering part 6 is arranged as a movable structure, specifically, the film covering roller 62 is arranged on the rotating shaft part 611, and then the limiting cap 612 is arranged on the upper end of the rotating shaft part 611, so as to limit the film covering roller 62 and prevent it from being separated from the rotating shaft part 611. After the film covering roller 62 is installed on the rotating shaft part 611, a certain space is formed between them, so that the film covering roller 62 can rotate on the rotating shaft part 611, and the rotating shaft part 611 can also be rotatably installed on the movable frame 61, so as to avoid the film covering roller 62 from being stuck on the rotating shaft part 611. During actual packing, one end of the packing film wound on the film covering roller 62 is connected with the battery module, and during rotation of the battery module, the driving structure 63 drives the sliding frame to reciprocate in the vertical direction, so as to wind the packing film on the outer side wall of the whole battery module in the vertical direction, and form an integrated packing structure between the battery module and the corner mounting part 1.

[0052] In this embodiment, the driving structure 63 is specifically provided as a motor screw rod 6312 structure. A vertical frame body 631 is a main mounting member, which is vertically mounted on the base 2. A vertical guide rod 6311 is arranged on the vertical frame body 631. The screw rod 6312 is also vertically mounted on the vertical frame body 631. When the second motor 632 is working, it drives the screw rod 6312 to rotate. The screw rod 6312 drives the movable frame 61 to move on the guide rod 6311. The second motor 632 rotates back and forth, so as to realize the reciprocating movement of the movable frame 61 in the vertical direction.

[0053] As described above, the tank structure includes at least two types. One type is provided as a first tank body 31. The first tank body 31 is suitable for packaging battery modules that are visually detected to have good appearance, slight deformation and damage, or do not exceed the safety limit conditions specified by the manufacturer, and have no direct safety risks. The packaged battery modules in the first tank body 31 are also filled with shock isolation plates between the inner wall of the tank and the battery modules.

[0054] As described above, if there is liquid leakage, deformation, serious damage, or traces of human disassembly, which exceeds the safety limit conditions specified by the manufacturer, the battery modules of this type are packaged by a second tank body 32. The second tank body 32 is provided with a partition plate 321. The partition plate 321 is provided with a plurality of water guide grooves 325 towards the middle position. The water guide grooves 325 are inclinedly arranged, with the downward end located at the center position of the partition plate 321. A through hole 323 is arranged at the center position of the partition plate 321. The battery liquid flows through the water guide grooves 325 to the through hole 323, and finally flows into the liquid storage cavity 322. One end of the partition plate 321 located in the liquid storage cavity 322 protrudes downward to avoid backflow of the battery liquid. A plurality of liquid discharge holes 324 are arranged on the outer wall of the lower end of the second tank body 32 for discharging the battery liquid. The liquid discharge holes 324 are sealed by sealing plugs during use.

[0055] In addition, a temperature sensing device 326 is arranged on the inner wall of the second tank body 32. A voice prompting structure 327 is arranged on the outer wall of the second tank body 32 and connected to the temperature sensing device 326. The temperature sensing device 326 can monitor the temperature in the tank in real time during transportation. Once an abnormal temperature is found, the voice prompting structure 327 will automatically issue an alarm to remind the transportation personnel. The tank material and the corresponding shock isolation material are made of high-temperature resistant materials, so as to avoid dangers as much as possible.

[0056] The above merely illustrates the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the technical concept of the present application and by using the content of the present application specification and drawings are included in the patent protection scope of the present application.
