[0029] This application provides a battery conveying device 200 and a battery processing equipment. By cooperating with the conveyor belt 222 and the carrier 100, the battery cells are automatically unloaded and loaded onto the conveyor belt 222 in sequence to achieve conveying, thereby simplifying the technical effect of battery unloading and transmission related equipment structure.

[0030] To better understand the above technical solutions, a detailed description of the technical solutions will be provided below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.

[0031] This application proposes a battery delivery device 200, such as... Figure 1 As shown, a carrier 100 is used to transfer batteries. The carrier 100 has rotational freedom to rotate around an axis, and its periphery has bearing surfaces 110. There are one or more bearing surfaces 110, each with an adsorption function to adsorb and fix the battery onto it. In one embodiment, the carrier 100 is a cylindrical roller, with the side of the cylinder defined as the bearing surface 110 for adsorbing the battery cells. After processing on the carrier 100 in the previous step, the battery cells are transferred by a conveying device 200. It should be noted that the vacuum adsorption function of multiple bearing surfaces 110 can be controlled individually, allowing the battery cells to be transferred one by one from the carrier 100 to the conveying device 200. For example, three sets of independent bearing surfaces 110 can be provided on the periphery of the carrier 100, each set controlled by a solenoid valve to open and close the vacuum, achieving group-by-group transfer of the battery cells. It is understood that the negative pressure function of the bearing surfaces 110 can be achieved by installing a negative pressure generator inside the carrier 100.

[0032] like Figure 2 As shown, the conveying device 200 includes a base 210, a conveying assembly 220, a lifting assembly 230, and a buffer assembly 240. The base 210 serves as the mounting base for the conveying assembly 220, the lifting assembly 230, and the buffer assembly 240. The conveying assembly 220 is used for conveying the battery. The lifting assembly 230 is used to adjust the distance between the conveying assembly 220 and the carrier 100. The buffer assembly 240 is used to buffer the battery. It is worth noting that the battery in this application can be a single battery cell or a string of batteries, and both single battery cells and strings of batteries are suitable for the conveying device 200 proposed in this application.

[0033] The conveying assembly 220 is used for conveying the battery. For example... Figure 2 As shown, the conveying assembly 220 is connected to the base 210. The conveying assembly 220 is used to cooperate with the carrier 100 to transfer the battery from the carrier 100 to the conveying assembly 220 and convey it. The conveying assembly 220 includes a sub-base 221, a conveyor belt 222, and an adsorption member 223. The conveyor belt 222 is drivenly connected to the sub-base 221 and is used to drive and convey the battery. The conveyor belt 222 has adsorption holes 2221. The adsorption member 223 is fixedly connected to the sub-base 221 and is located on the side of the conveyor belt 222 away from the carrier 100. The adsorption member 223 is used to adsorb the battery cells through the adsorption holes 2221 so that the battery cells are adsorbed and fixed on the conveyor belt 222.

[0034] Furthermore, such as Figure 3 As shown, the conveying assembly 220 is located below the carrier 100. The conveying assembly 220 has an interaction area 2222, which is located directly below the carrier 100, allowing the battery on the carrier 100 to be transferred from the interaction area 2222 to the conveyor belt 222. The interaction area 2222 refers to a section of the conveyor belt 222, and the carrier 100 cooperates with the interaction area 2222 on the conveyor belt 222 to transfer the battery. In one embodiment, the interaction area 2222 is located at the starting end of the conveyor belt 222. To ensure stable battery transport and reduce the work done against gravity during oblique transport, the conveying assembly 220 is arranged horizontally or substantially horizontally, allowing the battery to be transported stably on a horizontal plane.

[0035] like Figure 3 As shown, the conveying assembly 220 is located directly below the carrier 100, and the overlapping area of ​​their vertical projections is defined as the interaction zone 2222, meaning the carrier 100 is located directly above the interaction zone 2222; preferably, it is positioned at the starting end of the conveyor belt 222. When the carrier 100 rotates until the bearing surface 110 aligns with the interaction zone 2222: the conveyor belt 222 comes into close contact with the surface of the carrier 100; the first end of the battery is attracted by the conveyor belt 222 through the adsorption hole 2221, and at the same time, the carrier 100 gradually releases the vacuum in the corresponding area. Subsequently, the battery cells are transferred sequentially onto the conveyor belt 222 under the combined action of the carrier 100's rotation and the conveyor belt 222's transmission. It should be noted that the bearing surface 110 of the carrier 100 is provided with segmented vacuum valves along the circumference. When rotating to the interaction zone 2222, the vacuum valve in the corresponding area closes, releasing the battery cells.

[0036] Specifically, such as Figure 4 As shown, the subbase 221 has a rectangular frame structure, and the conveyor assembly 220 is installed on the subbase 221. The conveyor belt 222 is connected to the subbase 221 via rollers 224 at both ends of the subbase 221, and at least one roller 224 is connected to a motor to drive the conveyor belt 222 (motor not shown).

[0037] like Figure 5As shown, the length of the adsorption element 223 is equal to or substantially equal to the conveying length of the conveyor belt 222, and / or the arrangement direction of the adsorption element 223 is parallel to or substantially parallel to the arrangement direction of the conveyor belt 222. Furthermore, the adsorption element 223 forms a negative pressure zone 2231, and multiple adsorption holes 2221 are provided, with the positions of the adsorption holes 2221 corresponding to the negative pressure zone 2231. Specifically, the adsorption component 223 is a long strip-shaped vacuum chamber plate, which is fixed on the sub-base 221. The adsorption component 223 is located below the conveyor belt 222 and is close to the conveyor belt 222. The length of the adsorption component 223 is consistent with the conveyor belt 222, and the arrangement direction of the adsorption component 223 is parallel to the transmission direction. The adsorption component 223 is connected to an external vacuum pump. When turned on, it forms a negative pressure zone 2231 along the direction of the conveyor belt 222. The position of the adsorption holes 2221 or the arrangement position of the adsorption holes 2221 corresponds completely to the position of the negative pressure zone 2231, so that the battery is uniformly adsorbed on the surface of the conveyor belt 222 without deviation or slippage during transmission.

[0038] like Figure 4 As shown, the lifting assembly 230 is used to adjust the distance between the conveying assembly 220 and the carrier 100. The lifting assembly 230 is connected between the base 210 and the conveying assembly 220, and is used to drive the conveying assembly 220 to rise and fall, thereby adjusting the distance between the conveyor belt 222 and the carrier 100. Specifically, the lifting assembly 230 includes a guide rod 232 and a cylinder 231. The guide rod 232 is telescopic and connected between the base 210 and the sub-base 221, and is used to guide the conveying assembly 220; the cylinder 231 is fixedly connected to the base 210 and acts on the sub-base 221.

[0039] In other words, such as Figure 4 As shown, the guide rod 232 is telescopic and vertically arranged. Both ends of the guide rod 232 are fixed to the base 210 and the sub-base 221 respectively, ensuring that the sub-base 221 does not tilt during lifting. The cylinder 231 is vertically installed on the base 210, and its piston rod is connected to the sub-base 221. The cylinder 231 drives the sub-base 221 to lift (the specific stroke is adjusted according to the battery thickness). The cylinder 231 pushes the conveyor belt 222 up to be close to the carrier 100, preventing the first battery from falling and impacting the platform due to gravity. Combined with the immediate adsorption of the adsorption component 223, the risk of fragmentation is minimized.

[0040] like Figure 6 As shown, the buffer assembly 240 is used to buffer the battery. The buffer assembly 240 includes a buffer box 241 for housing the battery. The buffer box 241 is located on the side of the conveyor belt 222 in the transmission direction and is fixedly connected to the base 210.

[0041] Specifically, the buffer box 241 is a cuboid structure, fixed to the side of the conveyor belt 222 in the transmission direction, with its height flush with the transmission plane of the conveyor belt 222, and its opening facing the gripping path of the robot arm. When the downstream process is not ready, the robot arm temporarily stores the batteries that have been transferred to the position in the buffer box 241. The box can be equipped with removable partitions to accommodate the classified storage of battery strings of different lengths, ensuring continuous operation of the production line.

[0042] The working process of the battery conveying device 200 provided in this application is as follows: The battery is vacuum-adsorbed onto the bearing surface 110 of the carrier 100 and awaits unloading. The cylinder 231 is activated, guided by the guide rod 232, driving the conveying assembly 220 to rise, reducing the distance between the conveyor belt 222 and the carrier 100, and preventing the first battery cell in the battery from falling naturally and hitting the table surface during the vacuum breaking process, causing fragmentation. At the same time, the adsorption element 223 is opened, generating negative pressure through the adsorption hole 2221. At this time, the vacuum on the bearing surface 110 aligned with the conveyor belt 222 is released, adsorbing the first battery cell and conveying it forward. The carrier 100 rotates in coordination with the conveying assembly 220, releasing the vacuum in sequence, so that the battery can be smoothly transferred from the carrier 100 to the conveyor belt 222. The conveyor belt 222 conveys the battery forward, and the robot completes the unloading. If the next process has not been completed, the robot places the battery in the buffer box 241 of the buffer assembly 240 to realize the temporary storage function.

[0043] A battery processing apparatus for processing batteries includes the aforementioned battery conveying device 200 for unloading batteries.
