[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0043] During the battery manufacturing process, the storage and turnover environment of solar cells needs to maintain a certain degree of cleanliness and low oxidation state. In particular, the impact of ozone on cells should be avoided as much as possible. Because ozone is a common highly oxidizing gas, it is very easy to oxidize cells, seriously affecting the quality of cells. This situation is especially difficult to avoid during the transportation and caching of solar cells. If ozone treatment equipment is installed in the entire workshop, its hardware cost and maintenance cost are high, which increases the burden on the enterprise. Secondly, although the existing AGV design can maintain the cleanliness and low oxidation state of the cells to a certain extent, in actual operation, it is still difficult to completely avoid the contact between the cells and the external environment, thereby affecting the quality of the cells; finally, the existing technical solutions do not have the technology to remove ozone, and cannot give full play to the leading role of robots in the storage and turnover process of cells, thus affecting the quality of cell products.

[0044] In order to solve the above problems, this embodiment provides a dedicated robot for battery cell turnover.

[0045] Reference Figure 1 As shown, a special robot for battery cell turnover includes a moving body 300, a buffer box 200, a rolling shutter mechanism 400 and a deozonation device 100.

[0046] The mobile body 300 may adopt an AMR (Autonomous Mobile Robot) type chassis structure to enable the robot to move between different locations. A debugging window is designed on the side of the mobile body 300, which facilitates debugging and maintenance of the controller without tools.

[0047] A cache box 200 is designed above the mobile body 300. The cache box 200 has a storage space inside and extends horizontally to one side to form an entrance and exit for materials to enter and exit the storage space.

[0048] The rolling shutter mechanism 400 is disposed at the entrance and exit of the buffer box 200 , and the battery cells can be entered and exited by opening the rolling shutter mechanism 400 .

[0049] The upper part of the buffer box 200 is provided with a deozonation device 100. The deozonation device 100 is arranged on the side of the top of the buffer box 200 away from the entrance and exit. The deozonation device 100 can filter and purify the external air and then input it into the buffer box 200, so that the air pressure in the buffer box 200 is higher than the air pressure outside the buffer box 200, thereby preventing the floating dust impurities and ozone in the external air from entering the buffer box 200, and then preventing the materials in the buffer box 200 from being contaminated.

[0050] Combination Figure 2 and Figure 3 The deozonation device 100 includes a housing 101, and the housing 101 is formed with a vertical channel and a transverse channel. Among them, the vertical channel is used to introduce and filter air into the cache box 200, and the inside is sequentially provided with a fan 102, an air filter element 103 and an ozone aluminum honeycomb 104 from top to bottom. The fan 102 is fixedly connected to the top inner wall of the housing 101. The air filter element 103 is designed below the fan 102, and the transverse channel is used to push and pull the air filter element 103 horizontally to install and remove the air filter element 103 and the ozone aluminum honeycomb 104, and provide a space for placing the air filter element 103. The fan 102 inhales the air above, blows it into the ozone aluminum honeycomb 104 through the air filter element 103, and finally flows out from the bottom into the cache box 200. In this process, the air filter element 103 filters the dust and bacteria in the air, and the ozone aluminum honeycomb 104 reacts catalytically with ozone, which can effectively remove ozone.

[0051] The bottom edge of the shell 101 extends inwardly along the horizontal direction toward the bottom of the inner side of the vertical channel to form a folded edge 1013 for supporting the ozone aluminum honeycomb 104. Figure 4 and Figure 5The housing 101 includes a first housing 1011 and a second housing 1012. A vertical channel is formed inside the first housing 1011. An opening is provided at the top of the first housing 1011. The fan 102 is mounted on the top inner wall of the first housing 1011 and is opposite to the above opening. The second housing 1012 is fixedly mounted at a lower position of the vertical channel inside the first housing 1011. The second housing 1012 is a frame-type structure. In addition, the bottom of the second housing 1012 extends inwardly in the horizontal direction to form a folded edge 1013 for supporting the ozone aluminum honeycomb 104. In addition, a transverse channel that penetrates the first housing 1011 is horizontally opened in the middle of the first housing 1011. When installing the ozone aluminum honeycomb 104, it is placed into the housing 101 from the horizontal direction of the transverse channel and falls into the second housing 1012. The folded edge 1013 can support the ozone aluminum honeycomb 104. The air filter element 103 is further pushed into the transverse channel to achieve the installation of the air filter element 103. The process of disassembly is the opposite of that of installation. First, the air filter element 103 is pulled out, and then the ozone aluminum honeycomb 104 is taken out. Therefore, the air filter element 103 can be installed and disassembled in a push-pull manner. The ozone aluminum honeycomb 104 is also installed through a transverse channel. During disassembly, it is only necessary to lift the ozone aluminum honeycomb 104 upward to the transverse channel from the inside of the cache box 200, and then take the ozone aluminum honeycomb 104 out of the transverse channel. In this way, the air filter element 103 and the ozone aluminum honeycomb 104 can be replaced regularly more conveniently. In addition, the bottom edge of the first shell 1011 extends horizontally outward to form a fixed edge, which is used to fix the shell 101 to the upper part of the cache box 200.

[0052] In a further embodiment, Figure 2 As shown, a protective cover 105 for protecting the fan 102 is provided on the top of the housing 101. A plurality of through holes are provided on the protective cover 105. By providing the protective cover 105, impurities in the working environment can be effectively filtered to a certain extent to extend the service life of the fan 102.

[0053] like Figure 6 As shown, the rolling shutter mechanism 400 includes a door frame structure 500, a driving assembly 600, a rolling shutter 700 and a guiding assembly.

[0054] The door frame structure 500 includes a fixed bracket 501, a side panel 502 and a bottom panel 503. The fixed bracket 501 is horizontally arranged at the top of the cache box 200. In the present embodiment, the fixed bracket 501 includes a first bracket and a second bracket arranged in parallel, the first bracket and the second bracket are horizontally arranged at the top of the cache box 200, and the first bracket and the second bracket extend horizontally along the inner depth direction of the cache box 200 to form a basis for installing the side panel 502 and the bottom panel 503. The first bracket and the second bracket can be made of aluminum profiles. The top of the side panel 502 is fixedly connected to the side of the fixed bracket 501. The bottom of the side panel 502 is fixedly connected to the bottom panel 503, and a plurality of connectors are arranged on the inner side of the side panel 502 to connect to the inner wall of the cavity of the cache box 200. Among them, the connector is provided with a plurality of connecting holes so that the side panel 502 and the inner wall of the cache box 200 can be connected by bolts.

[0055] The driving assembly 600 is arranged on the fixed bracket 501 of the door frame structure 500, and the rolling curtain 700 can be driven to be wound and raised and lowered by the driving assembly 600. In this embodiment, the driving assembly 600 includes an active roller with power input, and the top of the rolling curtain 700 is connected to the active roller. The rolling curtain 700 can be wound by rotating the active roller, thereby realizing the lifting and lowering of the rolling curtain 700. Specifically, the power input of the active roller can be driven by setting a motor and a transmission sprocket to drive the active roller to rotate; an electric roller can also be used as the active roller. The rolling curtain 700 and the active roller can be fixed by adhesive, such as double-sided tape. Of course, in order to adjust the winding angle of the rolling curtain 700 and keep the rolling curtain 700 in a taut state when winding the active roller, a driven roller without power input can also be set on one side of the active roller, so that the top of the rolling curtain 700 is connected to the active roller after winding the driven roller. Among them, the material of the rolling curtain 700 is preferably polyvinyl chloride (PVC).

[0056] Combination Figure 6 and Figure 7 The guide assembly includes a guide track 800 disposed on the inner side of the door frame structure 500 and a guide mechanism 900 disposed at the bottom of the rolling shutter 700. The guide mechanism 900 cooperates with the guide track 800 to guide the rolling shutter 700 to rise and fall along the height direction of the door frame structure 500.

[0057] Specifically, there are two guide rails 800, which are symmetrically arranged on the inner side of the side plate 502. The guide rail 800 has a guide groove 801 along its length. The opposite side of the guide rail 800 forms a side opening 802 whose width is smaller than the guide groove 801, and the side opening 802 extends from one end of the guide rail 800 to the other end.

[0058] like Figure 8As shown, the guide mechanism 900 includes a lining plate 901, a counterweight clamping plate 902 and a roller 903. The lining plate 901 is attached to the bottom of the rolling curtain 700 along the width direction of the rolling curtain 700. There are two counterweight clamping plates 902, which respectively cooperate with one side of the lining plate 901 and one side of the rolling curtain 700 to clamp the lining plate 901 and the rolling curtain 700, and then fix them by screws or bolts or other threaded fasteners, so that the bottom of the rolling curtain 700 maintains a certain counterweight weight, so that the rolling curtain 700 is in a straight state. The two ends of the lining plate 901 and the rolling curtain 700 extend horizontally into the guide groove 801 of the guide track 800. The roller 903 is installed at the end of the lining plate 901 and rolls with the guide groove 801 of the guide track 800. The guide groove 801 is configured to limit the roller 903 from two directions, thereby preventing the rolling curtain 700 from shaking, and preventing the rolling curtain 700 from rubbing against the guide rail 800, so as to reduce the wear of the rolling curtain 700 and the wear debris generated by the wear. In addition, since the two side edges of the rolling curtain 700 also extend into the guide groove 801 of the guide rail 800, the sealing performance of the rolling curtain 700 can be improved, and the external polluted air can be reduced from flowing into the interior of the cache box 200. In this embodiment, while avoiding the friction between the lining plate 901 and the guide rail 800, the spacing between the side openings 802 of the guide rail 800 should be as small as possible, so that the sealing performance of the rolling curtain mechanism 400 can be enhanced.

[0059] In a further embodiment, in combination Figure 8 and Fig. 9 The outer surface of the roller 903 forms a tapered cut edge 9031, and the inner wall edge of the guide groove 801 of the guide rail 800 forms an edge portion 803 that is adapted to the tapered cut edge 9031. The edge portion 803 can be formed by chamfering, which facilitates the automatic alignment of the roller 903 in the guide groove 801, so that the guide rail 800 provides two-way limitation for the roller 903 in the horizontal direction.

[0060] In a further embodiment, in combination Figure 7 and Fig. 9Due to the high frequency use of the rolling shutter mechanism 400, the wear of the roller 903 becomes inevitable. If the severely worn roller 903 cannot be replaced in time, it is very likely to cause sliding friction between the lining plate 901 and the guide rail 800. Therefore, in this embodiment, the edges at both ends of the lining plate 901 are processed to form arc edges 9011, and a process groove 9012 is provided along the thickness direction of the lining plate 901 to facilitate the processing of the arc edges 9011 of the lining plate 901. If right-angle edges are used, during the lifting and lowering process of the rolling shutter 700, the guide rail 800 will be frictionally cut, resulting in poor lifting and lowering of the rolling shutter 700, and more grinding chips will be generated. This design can improve the smoothness of the lifting and lowering of the rolling shutter when the lining plate 901 rubs against the guide rail 800, reduce the wear of the lining plate 901 and the guide rail 800 as much as possible, and facilitate the discharge of grinding chips.

[0061] Take an AMR (Automated Guided Vehicle) with high precision, high efficiency and good stability as an example. The robot has a maximum load capacity of 200 kg, a maximum speed of 1.5 m / s, and a positioning accuracy of ±2 mm, which can meet the storage and turnover needs of solar cells.

[0062] The cache box 200 is integrated on the mobile body 300 of the AMR. The cache box 200 is designed as two layers, made of steel plate or aluminum plate to ensure its durability and sealing. A roller shutter mechanism 400 is designed at the front end of the cache box 200, and a deozonation device 100 is arranged on the top. The size of the roller shutter mechanism 400 can be designed into various sizes according to actual needs. The material is fire-retardant material and can be quickly and completely opened and closed. The fan 102 of the deozonation device 100 is a silent type, the wind pressure is not less than 600Pa, and the filtration efficiency is 99.97%, which can effectively remove dust and bacteria in the air. The deozonation device 100 adopts a catalytic decomposition method, uses nanotechnology and inorganic non-metallic material formula, uses ozone aluminum honeycomb 104 as a carrier, and carries active ingredients on the surface. Under normal temperature conditions, it can quickly and efficiently catalytically decompose low and medium concentrations of ozone into oxygen without additional energy consumption and no secondary pollutants.

[0063] Based on the instructions of the dispatching system and the corresponding navigation algorithm, AMR autonomously drives to different machines to transfer and deliver battery cells.

[0064] When the AMR is docked with the machine, the rolling shutter mechanism 400 will automatically open to facilitate docking with the machine; after the docking is completed, the rolling shutter mechanism 400 will close to form a closed space to protect the battery cell from the influence of the external environment.

[0065] During the waiting and transportation process, the deozonizer 100 will continue to work, blowing filtered clean air without ozone into the cache box 200 to maintain the cleanliness and low oxidation state of the inside of the cache box 200, and protect the solar cells from being contaminated and oxidized by ozone during transportation.

[0066] It can be seen from the above that the dedicated battery cell turnover robot provided in this embodiment can effectively solve the cleanliness and low oxidation state problems during the storage and turnover of solar cell cells, reduce manpower and material costs, and improve work efficiency.

[0067] 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 from these are still within the scope of protection of the invention of the utility model.
