In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0059] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0060] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0061] Such as Figure 1As shown in the figure, this is a preferred embodiment of the detection device for the lithium battery cover of the present utility model. This kind of detection device for the lithium battery cover is used to perform surface detection on the lithium battery cover 6. The above-mentioned detection device for the lithium battery cover includes: a workbench 1, a transportation component 2, a detection component, and a sorting component. The workbench 1 is the main load-bearing member. And for the convenience of indicating directions, the direction parallel to the width direction of the workbench 1 is denoted as the first direction, the direction parallel to the height direction of the workbench 1 is denoted as the second direction, and the direction parallel to the length direction of the workbench 1 is denoted as the third direction. The transportation component 2 is arranged on the workbench 1 and includes: an annular frame 201, a driving mechanism 202, a transportation mechanism 203, and a plurality of placing plates 204. The annular frame 201 is arranged on the workbench 1, and the driving mechanism 202 and the transportation mechanism 203 are arranged on the annular frame 201. The driving end of the driving mechanism 202 is connected to the transportation mechanism 203 and is used to drive the transportation mechanism 203 to move circumferentially along the annular frame 201, that is, the conveying direction of the transportation mechanism 203 is consistent with the shape of the annular frame 201. A plurality of placing plates 204 are arranged on the transportation mechanism 203 at intervals, and the lithium battery cover 6 to be tested is placed on the placing plates 204. The driving mechanism 202 is used to drive the transportation mechanism 203 to convey the placing plates 204 circumferentially along the annular frame 201 in a cycle. The detection component is arranged at the transportation component 2 and includes multiple groups of detection mechanisms arranged along the conveying direction of the transportation mechanism 203. Each group of detection mechanisms corresponds to a detection station, that is, the transportation component 2 is divided into each detection station. Between the starting detection station and the end detection station is the sorting station, and between the sorting station and the starting detection station is the loading station. The lithium battery cover 6 starts to be detected from the starting detection station until the full series of detections are completed at the end detection station, and then is picked up at the sorting station. The sorting component is arranged on the workbench 1 and is used to pick up the lithium battery cover 6 after detection at the sorting station. The sorting component includes a finished product sorting mechanism 401 and a defective product sorting mechanism 402. The finished product sorting mechanism 401 is used to pick out the finished lithium battery covers 6 after detection, and the defective product sorting mechanism 402 is used to pick out the defective lithium battery covers 6 after detection. Place the lithium battery cover 6 to be tested on each placing plate 204, and then the transportation mechanism 203 drives the placing plate 204 to move circumferentially along the annular frame 201. During the conveying process, different types of detections are performed on the lithium battery cover 6 through each detection mechanism. After the detection is completed, the finished products and defective products can be distinguished, and then the finished product sorting mechanism 401 and the defective product sorting mechanism 402 are used for sorting to separate the finished products from the defective products. This kind of detection device for the lithium battery cover not only realizes the automatic detection of the lithium battery cover 6, but also realizes the automatic sorting and storage of qualified products and unqualified products, with high automation and high production efficiency.

[0062] Furthermore, the lithium battery cover plate detection device further includes a feeding assembly 5 disposed between the starting detection station and the end detection station, corresponding to the loading station. The feeding assembly 5 is used to transport the lithium battery cover plate 6 to be tested onto the object placing plate 204 between the starting detection station and the end detection station. In this embodiment, the loading station is adjacent to the upstream of the starting detection station, that is, the feeding assembly 5 is disposed at an object placing plate 204 upstream of the starting detection station.

[0063] As Figure 2 , Figure 3 shown, the feeding assembly 5 includes: a second mounting seat 501, a material taking mechanism 502, a feeding mechanism 503, and a feeding and transporting mechanism 504. The second mounting seat 501 is disposed on the workbench 1, and the lithium battery cover plate 6 to be tested is placed on the side away from the workbench 1. The material taking mechanism 502, the feeding mechanism 503, and the feeding and transporting mechanism 504 are all disposed on the second mounting seat 501. Among them, the feeding and transporting mechanism 504 is disposed along the third direction, that is, the feeding and transporting mechanism 504 transports the lithium battery cover plate 6 to be tested along the third direction. Specifically, the feeding and transporting mechanism 504 is a chain drive mechanism, which includes: a second power member and a second transporting member 5041. The second power member is preferably a motor, and the second transporting member 5041 is preferably a chain, a transmission wheel, and a transmission shaft. Two transmission shafts are spaced along the first direction, and two transmission wheels are disposed at both ends of each transmission shaft. Chains are disposed on the two transmission wheels on the same side of the two transmission shafts. The lithium battery cover plate 6 to be tested is placed between adjacent teeth of the chain. The motor drives the transmission wheel to rotate, driving the chain to rotate, and transporting the lithium battery cover plate 6 on the chain from the end away from the workbench 1 to the end close to the workbench 1.

[0064] In other embodiments, the feeding and transporting mechanism 504 may also be other transporting mechanisms 203 such as a belt 2032 and a guide rail.

[0065] The material taking mechanism 502 is located at one end of the feeding and transporting mechanism 504 away from the transporting assembly 2, and is used to place the cover plate to be detected on the feeding and transporting mechanism 504. The material taking mechanism 502 includes: a fifth driving member 5021 and a fifth clamping member 5022. The fifth driving member 5021 is arranged on the second mounting seat 501, and the fifth clamping member 5022 is connected to the fifth driving member 5021. Specifically, the fifth driving member 5021 includes two cylinders. One of the cylinders is connected to the second mounting seat 501. This cylinder can extend and retract along the third direction, and its driving end is connected to another cylinder. The other cylinder can extend and retract along the second direction, and the driving end of the other cylinder is provided with the fifth clamping member 5022. The fifth clamping member 5022 includes a mounting plate and suction cups. A plurality of suction cups are arranged at the bottom of the mounting plate, and the suction cups are used to suck the cover plate of the lithium battery to be detected 6. The process of taking materials is as follows: the cover plate 6 of the lithium battery to be detected is adsorbed by the suction cups, then the height of the suction cups is lifted by the cylinders, and then it is moved towards the side close to the workbench 1 by the cylinders until it is above the second conveying member 5041. Then the height of the suction cups is lowered, and the suction cups are released, so that the cover plate 6 of the lithium battery to be detected falls onto the second conveying member 5041, and is conveyed from one end away from the workbench 1 to one end close to the workbench 1 by the second conveying member 5041.

[0066] The feeding mechanism 503 is located at one end of the feeding and transporting mechanism 504 close to the transporting assembly 2, and is used to place the cover plate to be detected on the feeding and transporting mechanism 504 onto the placing plate 204. The structure of the feeding mechanism is similar to that of the material taking mechanism 502. The feeding mechanism includes: a sixth driving member 5031 and a sixth clamping member 5032. The sixth driving member 5031 is arranged on the second mounting seat 501, and the sixth clamping member 5032 is connected to the sixth driving member 5031. Similarly, the sixth driving member 5031 also includes two cylinders. One of the cylinders is connected to the second mounting seat 501. This cylinder can extend and retract along the third direction, and its driving end is connected to another cylinder. The other cylinder can extend and retract along the second direction, and the driving end of the other cylinder is provided with the sixth clamping member 5032. The sixth clamping member 5032 includes a mounting plate and suction cups. A plurality of suction cups are arranged at the bottom of the mounting plate, and the suction cups are used to suck the cover plate of the lithium battery to be detected 6. The process of feeding materials is as follows: the height of the suction cups is lowered, the cover plate 6 of the lithium battery to be detected is adsorbed by the suction cups, then the height of the suction cups is lifted by the cylinders, and then it is moved towards the side close to the workbench 1 by the cylinders until it is above the placing plate 204 at the feeding station. Then the suction cups are lowered and released, so that the cover plate 6 of the lithium battery to be detected falls onto the placing plate 204. With the continuous operation of the material taking mechanism 502, the feeding mechanism 503 and the feeding and transporting mechanism 504, continuous feeding work can be achieved.

By rotating the servo motor 2021, the rotating wheels 2031 and the belt 2032 can be driven to rotate, and one end of the storage plate 204 is connected to the belt 2032. When the belt 2032 rotates to drive the storage plate 204 to rotate, the track 2011 plays a guiding and supporting role, making the movement process of the storage plate 204 more stable. In this embodiment, a total of sixteen storage plates 204 are provided.

[0088] The working process of the sorting assembly is as follows: After the lithium battery covers 6 are detected, they are sent to the first transport mechanism 404 by the first transfer mechanism 403. If the lithium battery covers 6 are defective products, they are sorted to the defective product storage area by the defective product sorting mechanism 402. If they are finished products, they move from one end close to the detection assembly to the other end away from the detection assembly on the first transport mechanism 404. According to this process, the first transport mechanism 404 is gradually filled with the finished product lithium battery covers 6, and then the finished product sorting mechanism 401 directly places these finished product lithium battery covers 6 on the cover plate holder 7 in the finished product storage area. When a cover plate holder 7 is full, the fourth driving member 4014 and the fourth clamping member 4015 transport the empty cover plate holder 7 and stack it on the cover plate holder 7 that has just been filled with the finished product lithium battery covers 6. When the cover plate holders 7 filled with the finished product lithium battery covers 6 in the finished product storage area accumulate to a certain height, the transport cart 4016 transports these cover plate holders 7 away.

[0089] The working process of the lithium battery cover plate detection device in this embodiment is described as follows:

[0090] The area around the detection component can be sequentially divided into: a loading station, twelve detection stations, and a sorting station, corresponding to sixteen storage plates 204. And the stations are fixed while the storage plates 204 rotate cyclically. Except that there are three storage plates 204 corresponding to the sorting station, each station in the loading station and the twelve detection stations corresponds to one storage plate 204.

[0091] First, the feeding component 5 continuously feeds the lithium battery cover plate 6 to be detected onto the storage plate 204 at the loading station. As the transportation mechanism 203 rotates, it successively passes through twelve detection stations and is subjected to twelve - process detection by the detection mechanism. After the detection, it arrives at the sorting station. According to the detection results, it is distinguished into qualified products and defective products. The qualified products are sorted to the qualified product storage area through the qualified product sorting mechanism 401, and the defective products are sorted to the defective product storage area through the defective product sorting mechanism 402.

[0092] Obviously, the above - mentioned embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
