[0002] In the automated production process of battery cells, it is inevitable that there will be various defects in the appearance of some products, which not only affect the appearance but also have a greater impact on the normal use of the products. For example, there are defects such as large waves on the top cover, surface steps, warping of the explosion-proof valve, scratches, electrolyte contamination, dirt, pits and breakages on the appearance of the battery cell. Therefore, it is necessary to detect the appearance of the battery cell and pick out the products with appearance defects.

This detection method has disadvantages such as high labor consumption and low efficiency, and there is also a risk of missed detection, so it is easy to cause defective products to flow into the market.

[0056] At present, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0057] In the automated production process of battery cells, it is inevitable that there will be various defects in the appearance of some products, which not only affect the appearance but also have a greater impact on the normal use of the products. For example, there are defects such as large waves on the top cover, surface steps, warping of the explosion-proof valve, scratches, electrolyte contamination, dirt, pits and damage on the appearance of the battery cell. Therefore, it is necessary to detect the appearance of the battery cell and pick out the products with appearance defects.

[0058] However, the means adopted for the appearance inspection of traditional battery cells are basically manual visual inspection. This inspection method has disadvantages such as high labor consumption and low efficiency, and there is also a risk of missed inspection, so it is easy to cause defective products to flow into the market.

[0059] To solve the problem of low efficiency in the appearance inspection process of battery cells, the present application proposes a battery cell detection system and a battery production line having the battery cell detection system. By using the battery cell detection system of the present application, the qualified battery cells and unqualified battery cells can be conveyed in the same predetermined direction respectively, so as to facilitate the operator to process the qualified products and unqualified products in the predetermined direction respectively, and improve the detection efficiency of the battery cells.

[0060] As Figure 1 shown, in the first aspect, the present application provides a battery cell detection system 100. The battery cell detection system 100 includes a conveying mechanism 10, a detection mechanism 20, a first transfer mechanism 30 and a re-inspection area 40. The conveying mechanism 10 is used to convey battery cells (not shown in the figure) in a predetermined direction. The detection mechanism 20 is arranged upstream of the conveying mechanism 10 along the predetermined direction and is used to detect the appearance of the battery cells. The detection mechanism 20 is provided with a qualified product outflow area 21 and an unqualified product outflow area 22. The qualified product outflow area 21 and the unqualified product outflow area 22 are respectively used to convey battery cells in the direction towards the conveying mechanism 10. The first transfer mechanism 30 is arranged between the conveying mechanism 10 and the detection mechanism 20 along the predetermined direction. The first transfer mechanism 30 is configured to selectively dock with the qualified product outflow area 21 and the unqualified product outflow area 22, and is used to transfer the qualified battery cells in the qualified product outflow area 21 and the unqualified battery cells in the unqualified product outflow area 22 to the conveying mechanism 10 respectively, and convey the qualified battery cells and unqualified battery cells in the predetermined direction through the conveying mechanism 10. The re-inspection area 40 is arranged downstream of the conveying mechanism 10 along the predetermined direction. The conveying mechanism 10 is used to convey battery cells to the re-inspection area 40. The re-inspection area 40 is provided with an alarm unit 43, and the alarm unit 43 is configured to be able to issue various alarm signals according to the appearance detection result of the battery cells.

[0061] Specifically, the conveying mechanism 10 for conveying battery cells in a predetermined direction can be a conveyor belt structure. The battery cells are placed on the conveyor belt and move together with the conveyor belt. Among them, Figure 1The direction indicated by the straight-line arrow is the predetermined direction. In order to reduce the length dimension of the conveying mechanism 10 in a single direction, the conveying mechanism 10 includes two structural parts arranged at an angle, and the respective conveying directions of the two structural parts together form the predetermined direction. Optionally, the conveying mechanism 10 includes a steering assembly 13, and the steering assembly 13 is arranged between the two ends of the conveying mechanism 10 along the predetermined direction, so that the conveying mechanism 10 conveys the battery cells along Figure 1 the direction of the straight-line arrow shown, and can reduce the length dimension of the conveying mechanism 10 in a single direction. In some embodiments of the present application, the conveying mechanism 10 can also convey the battery cells linearly in the first direction.

[0062] The detection mechanism 20 is used to detect the appearance of the battery cells, including but not limited to detecting the top cover and the housing of the battery cells. Among them, the detection of the top cover includes whether there are scratches, dents, damages, electrolyte contamination, explosion-proof valve protrusions, etc. on the surface of the top cover. The detection of the housing includes whether there are scratches, dents, damages, electrolyte contamination, etc. on the surface of the housing. The detection mechanism 20 can include an image collector, and the image collector can be a CCD camera. A CCD camera is a camera that uses a CCD (Charge Coupled Device) as an image sensor. The appearance information of the battery cells is collected by the image collector, so as to judge whether there are problems with the appearance of the battery cells. According to the fact that there are no problems with the appearance of the battery cells, the battery cells are placed in the qualified product outflow area 21, and according to the fact that there are problems with the appearance of the battery cells, the battery cells are placed in the unqualified product outflow area 22. Among them, a push rod can be provided in the detection mechanism 20, and the push rod can push the qualified battery cells to the qualified product outflow area 21 according to the appearance detection result of the battery cells, or the push rod can push the unqualified battery cells to the unqualified product outflow area 22 according to the appearance detection result of the battery cells. Among them, the qualified product outflow area 21 and the unqualified product outflow area 22 are also respectively provided with a conveying component, and the conveying component is used to convey the battery cells in the direction towards the conveying mechanism 10. Among them, the conveying component can be a conveyor belt.

[0063] Due to the structural limitations of the detection mechanism 20, the qualified product outflow area 21 and the unqualified product outflow area 22 are not necessarily aligned with the conveying mechanism 10 along the predetermined direction at the same time, that is, at least one of the qualified product outflow area 21 and the unqualified product outflow area 22 cannot be completely within the range of the inlet end of the conveying mechanism 10. Therefore, the first transfer mechanism 30 is arranged between the conveying mechanism 10 and the detection mechanism 20 along the predetermined direction, and the first transfer mechanism 30 can be selectively docked with the qualified product outflow area 21 and the unqualified product outflow area 22, so that the first transfer mechanism 30 transfers the qualified battery cells in the qualified product outflow area 21 to the conveying mechanism 10, or the first transfer mechanism 30 transfers the unqualified battery cells in the unqualified product outflow area 22 to the conveying mechanism 10.

[0064] The re-inspection area 40 can be provided downstream of the conveying mechanism 10 to re-inspect the battery cells, especially the non-conforming products. The re-inspection process can be carried out by machine re-inspection or manual visual re-inspection. Among them, the machine re-inspection includes using an image collector for re-inspection. Among them, the re-inspection area 40 is provided with an alarm unit 43, and the alarm unit 43 is configured to be able to emit a variety of alarm signals according to the appearance detection result of the battery cell, so as to remind the operator of the type of problem of the battery cell. Optionally, the alarm unit 43 may include a plurality of indicator lights, and the plurality of indicator lights can display different colors according to the type of problem of the battery cell. Optionally, the plurality of indicator lights may include a green indicator light, a yellow indicator light, and a red indicator light. The battery cells entering the re-inspection area 40 can be re-inspected by an image collector, and the image collector lights up different indicator lights according to the detected problems of the battery cells. Among them, when there is no problem with the appearance of the battery cell, the green indicator light lights up, and the operator does not need to operate on the battery cell, and the battery cell can automatically enter the next process. When there are minor problems on the outside of the battery cell and they can be solved on-site, such as there are minor protrusions on the outer surface of the battery cell or electrolyte remains on the surface, the yellow indicator light lights up, and the operator can handle the above appearance problems on-site and put the battery cell after the problem is solved into the next process. When there are major problems on the outside of the battery cell and they cannot be solved on-site, such as there are large scratches or surface damage on the outer surface of the battery cell, the red indicator light lights up, and the operator needs to remove the corresponding battery cell from the re-inspection area 40 and return it for repair. Optionally, the re-inspection area 40 is also provided with a barcode scanner, and the barcode scanner can scan the battery cells after the problems are solved on-site, so as to cancel the yellow indicator light corresponding to the battery cell.

[0065] According to the battery cell detection system 100 of the present application, by configuring the first transfer mechanism 30 to selectively dock with the qualified product outflow area 21 and the non-qualified product outflow area 22, and conveying the battery cells in the directions of the qualified product outflow area 21 and the non-qualified product outflow area 22 respectively towards the conveying mechanism 10, the conveying mechanism 10 can convey the qualified battery cells and the non-qualified battery cells along the same predetermined direction respectively, so as to facilitate the operator to process the qualified products and the non-qualified products respectively in the predetermined direction, and improve the detection efficiency of the battery cells. At the same time, by providing a re-inspection area downstream of the conveying mechanism and providing an alarm unit in the re-inspection area, the alarm unit can emit a variety of alarm signals according to different appearance detection results of the battery cells, so as to remind the operator to process the battery cells in different ways according to different alarm signals, thereby improving the detection efficiency of the battery cells and reducing the labor intensity of the operator.

[0066] Combined with Figures 1 to 4As shown, in some embodiments of the present application, the first transfer mechanism 30 includes a first support member 31 and a first transfer member 32. The first transfer member 32 is disposed between the conveying mechanism 10 and the detection mechanism 20 along a predetermined direction, and is connected to the first support member 31 in a manner that can move along the first direction X. The first transfer member 32 is configured to selectively dock with the qualified product outflow area 21 and the unqualified product outflow area 22 during the movement along the first direction X, and is used to transfer battery cells to the conveying mechanism 10, wherein the first direction X is consistent with the arrangement direction of the qualified product outflow area 21 and the unqualified product outflow area 22.

[0067] Specifically, the first transfer member 32 is connected to the first support member 31 in a manner that can move along the first direction X. The first support member 31 can be a seat body, which is connected to the ground or other fixed members to support the movement of the first transfer member 32. During the movement of the first transfer member 32 along the first direction X, one end of the first transfer member 32 facing the detection mechanism 20 can be respectively docked with the qualified product outflow area 21 and the unqualified product outflow area 22, and the other end of the first transfer member 32 facing the conveying mechanism 10 can be docked with the conveying mechanism 10, so that the battery cells in the qualified product outflow area 21 are transferred to the conveying mechanism 10 through the first transfer member 32, or the battery cells in the unqualified product outflow area 22 are transferred to the conveying mechanism 10 through the first transfer member 32. Herein, "docked" means that the end of the first transfer member 32 can abut against the end of the detection mechanism 20 or the conveying mechanism 10, or there is a small gap. The small gap is configured such that the battery cells can be conveyed from the detection mechanism 20 to the first transfer member 32 and then conveyed to the conveying mechanism 10 through the first transfer member 32 without falling from the small gap.

[0068] By moving the first transfer member 32 along the first direction X and docking the first transfer member 32 with the qualified product outflow area 21, the first transfer member 32 can transfer the qualified products in the qualified product outflow area 21 to the conveying mechanism 10, and the qualified products are conveyed along the predetermined direction through the conveying mechanism 10; by moving the first transfer member along the first direction X and docking the first transfer member 32 with the unqualified product outflow area 22, the first transfer member 32 can transfer the unqualified products in the unqualified product outflow area 22 to the conveying mechanism 10, and the unqualified products are conveyed along the predetermined direction through the conveying mechanism 10, so that the qualified products and the unqualified products are conveyed along the same predetermined direction.

[0069] Combined Figures 1 to 4 As shown, in some embodiments of the present application, one of the first support member 31 and the first transfer member 32 is provided with a slide rail, and the other of the first support member 31 and the first transfer member 32 is provided with a slide groove, and the slide rail and the slide groove are connected in a manner that can slide along the first direction.

[0070] Specifically, a slide rail may be provided at the top of the first support member 31, and a chute slidably engaged with the slide rail may be provided at the bottom of the first transfer member 32. Among them, the slide rail and the chute extend along the first direction X, and the slide rail is inserted into the chute, so that the first transfer member 32 is connected to the first support member 31 in a manner capable of sliding along the first direction X.

[0071] The sliding cooperation process between the slide rail and the chute has high stability, which facilitates the stable movement of the first transfer member 32 along the first direction X. Thus, it is convenient to make the first transfer member 32 respectively dock with the qualified product outflow area 21 and the unqualified product outflow area 22 during the movement along the first direction X.

[0072] Combined with Figures 1 to 4 As shown, in some embodiments of the present application, the first transfer member 32 includes a first conveyor belt, and the first conveyor belt is configured to convey battery cells along a predetermined direction.

[0073] Specifically, a first conveyor belt is provided on the surface of the first transfer member 32, and the first conveyor belt can convey battery cells along a predetermined direction. Since the first transfer member 32 is provided between the conveying mechanism 10 and the detection mechanism 20, the predetermined direction here is only the direction of the detection mechanism 20 towards the conveying mechanism 10.

[0074] By providing the first conveyor belt, the structure of the conveyor belt is simple and easy to arrange, so that it is convenient for the first transfer member 32 to convey the battery cells of the detection mechanism 20 to the conveying mechanism 10 along the predetermined direction.

[0075] Combined with Figures 1 to 4 As shown, in some embodiments of the present application, the conveying mechanism 10 includes a first conveying line 11 and a second conveying line 12 arranged side by side along the first direction X. The first conveying line 11 and the second conveying line 12 are respectively used to convey battery cells along a predetermined direction, and the first direction X is consistent with the arrangement direction of the qualified product outflow area 21 and the unqualified product outflow area 22.

[0076] Specifically, in order to improve the conveying efficiency of the conveying mechanism 10, the conveying mechanism 10 includes the first conveying line 11 and the second conveying line 12 arranged side by side. Arranged side by side means that the conveying directions of the first conveying line 11 and the second conveying line 12 are the same or substantially the same, and the conveying planes of the first conveying line 11 and the second conveying line 12 are in the same plane or substantially in the same plane. Optionally, the first conveying line 11 and the second conveying line 12 can be conveyor belts respectively.

[0077] By setting up the first conveyor line 11 and the second conveyor line 12, the battery cells of the detection mechanism 20 can be conveyed to the first conveyor line 11 or the second conveyor line 12 through the first transfer mechanism 30, and the first conveyor line 11 and the second conveyor line 12 can be used to convey the battery cells along a predetermined direction respectively, so that the battery cells are jointly conveyed by the first conveyor line 11 and the second conveyor line 12, thereby improving the conveying efficiency of the conveying mechanism 10, and further improving the detection efficiency of the battery cell detection system 100.

[0078] Combination Figures 1 to 4 As shown, in some embodiments of the present application, the first transfer mechanism 30 is configured to be able to connect with the qualified product outflow area 21, and is used to transfer the battery monomers in the qualified product outflow area 21 to the first conveyor line 11 or the second conveyor line 12. The first transfer mechanism 30 is also configured to be able to connect with the unqualified product outflow area 22, and is used to transfer the battery monomers in the unqualified product outflow area 22 to the second conveyor line 12.

[0079] Specifically, in the production process of battery cells, although there are problems with the appearance of some battery cells, in general, the number of qualified battery cells is much greater than the number of unqualified battery cells. Therefore, if qualified products are transported only through a single conveyor line, the number of qualified products on the conveyor line will be too large, which may easily cause product accumulation on the conveyor line. If a single conveyor line only transports unqualified products, the number of battery cells on the conveyor line will be too small, thereby affecting the transportation efficiency and detection efficiency of the battery cells, resulting in a waste of resources. Therefore, the first transfer mechanism 30 is configured to be able to connect with the qualified product outflow area 21, and according to the distribution of battery cells on the conveying mechanism 10, the qualified battery cells are transferred to the first conveyor line 11 or the second conveyor line 12. The first transfer mechanism 30 is also configured to be able to connect with the unqualified product outflow area 22, and transfer the battery cells of the unqualified product outflow area 22 only to the second conveyor line 12.

[0080] The qualified products in the qualified product outflow area 21 can be transported to the first conveying line 11 or the second conveying line 12 through the first transfer mechanism 30, and are transported together through the first conveying line 11 and the second conveying line 12, thereby improving the transportation efficiency of the qualified products. The unqualified products in the unqualified product outflow area 22 can be transported to the second conveying line 12 through the first transfer mechanism 30, so that it is convenient for operators to re-inspect the unqualified products on the second conveying line 12, improve the re-inspection efficiency of the unqualified products, and reduce the labor intensity of the operators.

[0081] Combination Figures 1 to 4As shown, in some embodiments of the present application, the battery cell detection system 100 further includes a second transfer mechanism 50. The second transfer mechanism 50 is disposed between the conveying mechanism 10 and the re-inspection area 40 along a predetermined direction. The second transfer mechanism 50 is configured to selectively dock with the first conveyor line 11 and the second conveyor line 12, and is used to transfer the battery cells on the first conveyor line 11 and the second conveyor line 12 to the re-inspection area 40 respectively.

[0082] Since workstations for operators need to be set in the re-inspection area 40, limited by the structure of the re-inspection area 40, the first conveyor line 11 and the second conveyor line 12 are not necessarily aligned with the re-inspection area 40 along the predetermined direction at the same time, that is, the outlet ends of at least one of the first conveyor line 11 and the second conveyor line 12 cannot be completely within the receiving range of the re-inspection area 40. Therefore, by disposing the second transfer mechanism 50 between the conveying mechanism 10 and the re-inspection area 40 along the predetermined direction, and enabling the second transfer mechanism 50 to selectively dock with the first conveyor line 11 and the second conveyor line 12 respectively, the battery cells on the first conveyor line 11 and the second conveyor line 12 are transferred to the re-inspection area 40 through the second transfer mechanism 50.

[0083] By configuring the second transfer mechanism 50 to selectively dock with the first conveyor line 11 and the second conveyor line 12 respectively, and transferring the battery cells on the first conveyor line 11 and the second conveyor line 12 to the re-inspection area 40 respectively, it is convenient for the operator to process the qualified products and unqualified products in the re-inspection area 40 respectively, and the detection efficiency of the battery cells is improved.

[0084] Combined Figure 1 and Figure 5 As shown, in some embodiments of the present application, the second transfer mechanism 50 includes a second support member 51 and a second transfer member 52. The second transfer member 52 is disposed between the conveying mechanism 10 and the re-inspection area 40 along a predetermined direction, and is connected to the second support member 51 in a manner that can move along the second direction Y. The second transfer member 52 is configured to selectively dock with the first conveyor line 11 and the second conveyor line 12 during the process of moving along the second direction Y, and is used to transfer the battery cells to the re-inspection area 40, wherein the second direction Y is consistent with the arrangement direction of the first conveyor line 11 and the second conveyor line 12.

[0085] Specifically, the second transfer member 52 is connected to the second support member 51 in a manner that enables movement along the second direction Y. The second support member 51 can be a seat body, which is connected to the ground or other fixed members to support the movement of the second transfer member 52. During the movement of the second transfer member 52 along the second direction Y, one end of the second transfer member 52 facing the conveying mechanism 10 can be respectively docked with the first conveyor line 11 and the second conveyor line 12, and the other end of the second transfer member 52 facing the re-inspection area 40 can be docked with the re-inspection area 40. Thus, the battery cells on the first conveyor line 11 are transferred to the re-inspection area 40 through the second transfer member 52, or the battery cells on the second conveyor line 12 are transferred to the re-inspection area 40 through the second transfer member 52. Herein, "docking" means that the end of the second transfer member 52 can abut against the end of the conveying mechanism 10 or the end of the re-inspection area 40, or there is a small gap. The small gap is configured such that the battery cells can be conveyed from the conveying mechanism 10 to the second transfer member 52 and then conveyed to the re-inspection area 40 through the second transfer member 52 without falling through the small gap.

[0086] By moving the second transfer member 52 along the second direction Y and docking the second transfer member 52 with the first conveyor line 11, the second transfer member 52 can transfer the qualified products on the first conveyor line 11 to the re-inspection area 40, facilitating the re-inspection of the qualified products; by moving the second transfer member 52 along the second direction Y and docking the second transfer member 52 with the second conveyor line 12, the second transfer member 52 can transfer the qualified products and unqualified products on the second conveyor line 12 to the re-inspection area 40 respectively, facilitating the re-inspection of the qualified products and unqualified products respectively.

[0087] Combined Figure 1 and Figure 5 as shown, in some embodiments of the present application,

[0088] One of the second support member 51 and the second transfer member 52 is provided with a slide rail, and the other of the second support member 51 and the second transfer member 52 is provided with a slide groove, and the slide rail and the slide groove are connected in a manner that enables sliding along the second direction Y;

[0089] And / or, the second transfer member 52 includes a second conveyor belt, and the second conveyor belt is configured to convey the battery cells along a predetermined direction.

[0090] Specifically, a slide rail can be provided on the top of the second support member 51, and a slide groove that slidably cooperates with the slide rail can be provided on the bottom of the second transfer member 52. The slide rail and the slide groove extend along the second direction Y respectively, and the slide rail is inserted into the slide groove, so that the second transfer member 52 is connected to the second support member 51 in a manner that enables sliding along the second direction.

[0091] Specifically, a second conveyor belt is provided on the surface of the second transfer member 52, and the second conveyor belt can convey battery cells in a predetermined direction. Since the second transfer member 52 is provided between the conveying mechanism 10 and the re-inspection area 40, the predetermined direction here is only the direction from the conveying mechanism 10 towards the re-inspection area 40.

[0092] The sliding fit process between the slide rail and the sliding groove has high stability, which is convenient for stably moving the second transfer member 52 along the second direction Y. Thus, it is convenient for the second transfer member 52 to be docked with the first conveyor line 11 and the second conveyor line 12 respectively during the movement along the second direction Y. By providing the second conveyor belt, the structure of the conveyor belt is simple and easy to arrange, so that it is convenient for the second transfer member 52 to convey the battery cells on the first conveyor line 11 and the second conveyor line 12 to the re-inspection area 40 in a predetermined direction.

[0093] Combined Figure 1 and Figure 5 As shown, in some embodiments of the present application, the re-inspection area 40 includes a first re-inspection area 41 and a second re-inspection area 42 arranged side by side and spaced apart along the second direction Y. The second transfer mechanism 50 is configured to be able to be docked with the first conveyor line 11 and is used to transfer the battery cells on the first conveyor line 11 to the first re-inspection area 41. The second transfer mechanism 50 is also configured to be able to be docked with the second conveyor line 12 and is used to transfer the battery cells on the second conveyor line 12 to the second re-inspection area 42. The second direction Y is consistent with the arrangement direction of the first conveyor line 11 and the second conveyor line 12.

[0094] Specifically, the qualified products on the first conveyor line 11 can be transferred to the first re-inspection area 41, so that the first re-inspection area 41 can only re-inspect the qualified products, reducing the labor intensity of the operators. The qualified products and unqualified products on the second conveyor line 12 are respectively conveyed to the second re-inspection area 42, so that the second re-inspection area 42 needs to re-inspect the qualified products and unqualified products at the same time. Among them, the first re-inspection area 41 and the second re-inspection area 42 can be respectively provided with an alarm unit 43, thereby improving the detection efficiency and reducing the labor intensity of the operator.

[0095] The qualified products on the first conveyor line 11 can be conveyed to the first re-inspection area 41 through the second transfer mechanism 50, and the first re-inspection area 41 can simply re-inspect the qualified products, thereby improving the detection efficiency of the battery cells. The qualified products and unqualified products on the second conveyor line 12 can be conveyed to the second re-inspection area 42 through the second transfer mechanism 50, and the second re-inspection area 42 can re-inspect the qualified products and unqualified products, thereby improving the detection accuracy of the unqualified products.
