[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] In order to solve the technical problem in the prior art that battery cells are piled up at the bottom of a cleaning basket, resulting in a spray device being able to clean only the battery cells on the upper layer but not the battery cells at the bottom, resulting in incomplete cleaning, the utility model provides a retired power battery cleaning device that can achieve all-round cleaning of the battery cells.

[0036] See also Figure 1 , Figure 1 It is a schematic structural diagram of a retired power battery cleaning device in one embodiment of the utility model.

[0037] The retired power battery cleaning device includes a frame 1, a cleaning bucket 2, a first driving mechanism 3 and a cleaning component 4. The frame 1 is provided with an arc-shaped mounting groove 11; the cleaning bucket 2 is adapted to the mounting groove 11, and the cleaning bucket 2 is rotatably mounted on the mounting groove 11 along an axis in the horizontal direction. The cleaning bucket 2 is used to load the power battery to be cleaned, and the cleaning bucket 2 is hollow, and one end of the cleaning bucket 2 is open; the first driving mechanism 3 is provided on the frame 1, and the first driving mechanism 3 is connected to the cleaning bucket 2; and the cleaning component 4 is provided on the frame 1, and the cleaning component 4 extends from the opening into the cleaning bucket 2 to spray cleaning liquid into the cleaning bucket 2.

[0038] In this embodiment, the cleaning bucket 2 is rotatably installed in the installation groove 11 along the axis in the horizontal direction. The cleaning bucket 2 is hollowed out and one end of the cleaning bucket 2 is open; the first driving mechanism 3 is arranged on the frame 1, and the first driving mechanism 3 is connected to the cleaning bucket 2; the cleaning component 4 is arranged on the frame 1, and the cleaning component 4 extends from the opening into the cleaning bucket 2. When in use, the battery cells are first placed in the cleaning bucket 2, and then the first driving mechanism 3 drives the cleaning bucket 2 to rotate, so that the battery cells in the cleaning bucket 2 are continuously tumbling, and then the cleaning liquid is sprayed into the cleaning bucket 2 through the cleaning component 4. Since the battery cells are continuously tumbling under the rotation of the cleaning bucket 2, all the battery cells can be exposed under the cleaning component 4, so that the battery cells can be cleaned in all directions.

[0039] In one embodiment, see Figure 1 to Figure 2 The cleaning bucket 2 and the mounting groove 11 are detachably connected.

[0040] In this embodiment, since the cleaning bucket 2 is horizontally arranged in the mounting groove 11, it is not convenient to load the battery cells into the cleaning bucket 2. In order to facilitate the loading of the battery cells, the cleaning bucket 2 and the mounting groove 11 are arranged to be detachably connected, that is, the cleaning bucket 2 is placed in the mounting groove 11 and only abuts against the side wall of the mounting groove 11. The mounting groove 11 is only used to support the cleaning bucket 2. With this arrangement, the cleaning bucket 2 can be taken out of the mounting groove 11, making it convenient to load the battery cells into the cleaning bucket 2.

[0041] In one embodiment, see Figure 1 to Figure 2 The first driving mechanism 3 includes a rotating shaft 31, a driving wheel 32 and a driving motor 33. The rotating shaft 31 is rotatably mounted on the frame 1 along an axis in a first direction. The driving wheel 32 is fixedly mounted on the rotating shaft 31. The driving wheel 32 is used to abut against the side wall of the cleaning barrel 2. The main shaft of the driving motor 33 is connected to the rotating shaft 31, wherein the first direction is consistent with the axial direction of the mounting groove 11.

[0042] In this embodiment, the cleaning bucket 2 is detachably connected to the mounting groove 11. In order to avoid interference of the first driving mechanism 3 with the installation and disassembly of the cleaning bucket 2, the driving wheel 32 is driven by abutting against the side wall of the cleaning bucket 2. When in use, the driving motor 33 drives the rotating shaft 31 to rotate, thereby driving the driving wheel 32 to rotate. Since the driving wheel 32 abuts against the side wall of the cleaning bucket 2, when the driving wheel 32 rotates, the cleaning bucket 2 is driven to rotate by the friction between the driving wheel 32 and the side wall of the cleaning bucket 2, thereby achieving the purpose of driving the cleaning bucket 2 to rotate. In addition, the driving wheel 32 is in contact connection with the cleaning bucket 2 and will not interfere with the installation and disassembly of the cleaning bucket 2.

[0043] It should be noted that the first direction is a horizontal direction, and the cleaning bucket 2 is rotatably arranged along an axis in the first direction.

[0044] In one embodiment, see Figure 1 There are two first driving mechanisms 3 , and the two first driving mechanisms 3 are located on opposite sides of the installation groove 11 .

[0045] In this embodiment, by providing two driving mechanisms, the stability of the rotation of the washing bucket 2 can be improved, and even if one of the driving wheels 32 slips, it will not affect the rotation of the washing bucket 2.

[0046] In one embodiment, see Figure 4 A stopper 12 is provided at one end of the mounting groove 11 , and the opening end of the cleaning bucket 2 abuts against the stopper 12 to limit the power battery in the cleaning bucket 2 from falling from the opening end.

[0047] In this embodiment, the cleaning bucket 2 is placed horizontally in the installation groove 11, and the battery cells are piled on the side walls of the cleaning bucket 2. As the cleaning bucket 2 rotates, there is a risk that the battery cells will fall out from the open end of the cleaning bucket 2. By providing the stopping portion 12 at one end of the installation groove 11 and making the stopping portion 12 abut against the open end of the cleaning bucket 2, the stopping portion 12 can block the battery cells of the cleaning bucket 2, thereby effectively preventing the battery cells from falling out and eliminating safety hazards.

[0048] In one embodiment, see Figures 1 to 3 The retired power battery cleaning device also includes a loading and unloading mechanism 5 , which is disposed on the frame 1 , and is used to transport the cleaning bucket 2 into the installation groove 11 .

[0049] In this embodiment, the loading and unloading mechanism 5 can install the cleaning bucket 2 into the installation slot 11 or remove it from the installation slot 11, which has a high degree of automation, is easy to operate, and reduces the labor intensity of workers.

[0050] In one embodiment, see Figure 1 and Figure 3 The loading and unloading mechanism 5 includes a conveying frame 51, a second driving mechanism 52 and a push-pull assembly 53. The push-pull assembly 53, the conveying frame 51 and the mounting groove 11 are arranged at intervals along the first direction. The end of the conveying frame 51 away from the mounting groove 11 is rotatably installed on the frame 1 along the axis in the second direction, so as to have a conveying state in which it is rotated to a horizontal position to dock with the mounting groove 11 and a loading and unloading state in which it is rotated to a vertical position. The conveying frame 51 is provided with a receiving groove 511, and the receiving groove 511 is used for placing the cleaning bucket 2. The second driving mechanism 52 is connected to the conveying frame 51, and the push-pull assembly 53 is movably installed on the frame 1 along the first direction. In the conveying state, the push-pull assembly 53 is used to connect with the cleaning bucket 2, push the cleaning bucket 2 from the conveying frame 51 to the mounting groove 11 or pull the cleaning bucket 2 from the mounting groove 11 to the conveying frame 51, and the first direction and the second direction are arranged perpendicular to each other.

[0051] In this embodiment, the push-pull assembly 53, the conveying frame 51 and the mounting groove 11 are arranged in sequence along the first direction, and the receiving groove 511 is an arc-shaped groove adapted to the cleaning bucket 2. The conveying frame 51 is also provided with a baffle 512 at one end close to the push-pull assembly 53. When loading, the second driving mechanism 52 drives the conveying frame 51 to rotate upward, so that the conveying frame 51 rotates to a vertical state, and is in the loading and unloading state. At this time, the receiving groove 511 is vertically arranged, and the baffle 512 is located at the bottom of the receiving groove 511. At this time, the cleaning bucket 2 is vertically placed on the baffle 512, and the side wall of the cleaning bucket 2 is abutted against the side wall of the receiving groove 511. After the cleaning bucket 2 is placed, the second driving mechanism 52 drives the conveying frame 51 to rotate downward until the conveying frame 51 is in a horizontal state. At this time, the receiving groove 511 is docked with the mounting groove 11 and is in the conveying state. The groove 511 and the installation groove 11 form a conveying channel extending along the first direction. At this time, the cleaning bucket 2 is pushed by the push-pull assembly 53, and the cleaning bucket 2 is pushed from the accommodating groove 511 to the installation groove 11, and abuts against the stopping portion 12. The push-pull assembly 53 is separated from the cleaning bucket 2, that is, the loading is completed, and the battery cell can be cleaned. When unloading is required after cleaning, the push-pull assembly 53 is connected with the cleaning bucket 2, and the cleaning bucket 2 is pulled from the installation groove 11 to the accommodating groove 511, and the bottom of the cleaning bucket 2 abuts against the baffle 512. Then the push-pull assembly 53 is separated from the cleaning bucket 2, and the second driving mechanism 52 drives the conveying frame 51 to rotate upward and is in the loading and unloading state. At this time, the cleaning bucket 2 is in a vertical state, which is convenient for removing the cleaning bucket 2. By setting the loading and unloading mechanism 5, the installation and disassembly of the cleaning bucket 2 is realized, and the operation is simple and easy to use.

[0052] It should be noted that the specific form of the second driving mechanism 52 is not limited, as long as it can drive the conveying frame 51 to rotate. The second driving mechanism 52 can be one of a pneumatic cylinder, an electric cylinder and a hydraulic cylinder 531.

[0053] In one embodiment, see Figure 3 , an adsorption member is provided at the bottom of the cleaning barrel 2; the push-pull assembly 53 includes a hydraulic cylinder 531 and an electromagnet 532, the hydraulic cylinder 531 is installed on the frame 1, and the push rod of the hydraulic cylinder 531 is movably arranged along the first direction, and the electromagnet 532 is arranged at the end of the push rod of the hydraulic cylinder 531, corresponding to the adsorption member.

[0054] In this embodiment, the push-pull component 53 needs to be connected to the cleaning bucket 2 to push and pull the cleaning bucket 2, and also needs to be separated from the cleaning bucket 2 to avoid interfering with the movement of the cleaning bucket 2. Therefore, it can be achieved through the magnetic attraction cooperation between the electromagnet 532 and the adsorption component. When the electromagnet 532 is energized, the electromagnet 532 generates magnetic force, which can be magnetically matched with the adsorption component to connect the push-pull component 53 with the cleaning bucket 2. When the electromagnet 532 is powered off, the electromagnet 532 loses its magnetic force, and the electromagnet 532 cannot be magnetically matched with the adsorption component, thereby realizing the separation of the push-pull component 53 from the cleaning bucket 2.

[0055] In one embodiment, see Figure 3 to Figure 4 The cleaning component 4 includes a water tank 41, a water pump and a cleaning pipe 42. The water tank 41 is arranged on the frame 1. The cleaning pipe 42 is connected to the water tank 41 through the water pump. A plurality of water spray holes are arranged on the circumference of the cleaning pipe 42. The cleaning pipe 42 extends into the cleaning bucket 2.

[0056] In this embodiment, the cleaning component 4 is located at one end of the installation groove 11 away from the conveying rack 51, and the water tank 41 stores cleaning liquid. When in use, the water pump sprays the cleaning liquid in the water tank 41 from the water spray hole, and the cleaning pipe 42 is located in the cleaning bucket 2, which can directly spray the battery cell. Moreover, since the cleaning bucket 2 is hollow, the cleaning liquid can flow out of the cleaning bucket 2, and then with the rotation of the cleaning bucket 2, the battery cell can be cleaned in all directions.

[0057] In one embodiment, see Figure 3 The cleaning assembly 4 further includes a spray head 43, which is located above the mounting groove 11, and the spray head 43 is connected to the water tank 41 through the water pump.

[0058] In this embodiment, in order to improve the cleaning effect, the spray head 43 can be further arranged above the cleaning barrel 2. The spray head 43 sprays from top to bottom, and the cleaning liquid can pass through the cleaning barrel 2 to clean the battery cells in the barrel. The cleaning efficiency is improved by the coordinated use of the spray head 43 and the cleaning pipe 42.

[0059] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0060] First, load the battery cells into the cleaning bucket 2, and then place the cleaning bucket 2 on the conveying rack 51 in the loading and unloading state. At this time, place the cleaning bucket 2 vertically on the baffle 512, and make the side wall of the cleaning bucket 2 abut against the side wall of the receiving groove 511. After the cleaning bucket 2 is placed, the second driving mechanism 52 drives the conveying rack 51 to rotate downward until the conveying rack 51 is in a horizontal state. At this time, the receiving groove 511 is docked with the installation groove 11 in the conveying state, and the receiving groove 511 is in the receiving state. 11 and the installation groove 11 form a conveying channel extending along the first direction, at this time, the push rod of the hydraulic cylinder 531 extends out, so that the electromagnet 532 abuts against the adsorption member, the electromagnet 532 is energized, the electromagnet 532 and the adsorption member are magnetically matched, the push rod of the hydraulic cylinder 531 is connected to the cleaning bucket 2, and then the cleaning bucket 2 is pushed by the push rod of the hydraulic cylinder 531 until the cleaning bucket 2 is pushed from the accommodating groove 511 into the installation groove 11 and abuts against the stopper 12, and then After that, the electromagnet 532 is powered off, the push rod of the hydraulic cylinder 531 is separated from the cleaning bucket 2 and returns to the initial position to complete the loading. Then, the driving motor 33 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the driving wheel 32 to rotate, and the cleaning bucket 2 is driven to rotate by the driving wheel 32. The water pump is started, and the cleaning liquid is sprayed to the cleaning bucket 2 through the cleaning pipe 42 and the spray head 43 to complete the cleaning of the battery cell. After the cleaning is completed, the driving motor 33 and the water pump stop working, and the hydraulic cylinder 53 1 is extended again, so that the electromagnet 532 abuts against the adsorption member, and the cleaning bucket 2 is pulled from the installation groove 11 to the receiving groove 511, and the bottom of the cleaning bucket 2 abuts against the baffle 512, then the electromagnet 532 is powered off, and the push rod of the hydraulic cylinder 531 returns to the initial position, and the second driving mechanism 52 drives the conveying frame 51 to rotate upward and is in the loading and unloading state. At this time, the cleaning bucket 2 is in a vertical state, which is convenient for removing the cleaning bucket 2 to complete the cleaning work of the entire battery cell.
