Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing equipment technology, and more specifically, to a battery defect classification device. Background Technology

[0002] Lithium-ion batteries are widely used in the automotive and digital industries due to their high operating voltage, high energy density, long lifespan, and recyclability. In recent years, they have also seen rapid development in power batteries and energy storage. As battery requirements increase, the demands on battery production efficiency are also rising.

[0003] Battery manufacturing involves multiple processes, and defective products (NG batteries) are inevitably produced at each stage. To facilitate subsequent analysis and manual inspection, NG batteries need to be removed from the production line and classified. Current technology typically uses a single station to remove NG batteries and then classify them, which is inefficient and unsuitable for large-scale production, thus affecting the overall production efficiency of batteries.

[0008] The defective product classification unit includes a stopping unit and a storage unit disposed on opposite sides of the conveying unit. The storage unit includes multiple defective product storage channels, each used to store different categories of defective products. The stopping unit includes a pushing component and a blocking component. Multiple blocking components are arranged sequentially at intervals along the defective product conveying direction.

[0026] Combination Figure 1 As shown, this embodiment provides a battery defective product sorting device, including: a conveying unit, a defective product discharge unit 20, and a defective product sorting unit, wherein:

[0027] The conveyor unit is used to transport defective products;

[0028] The defective product removal unit 20 is located on one side of the conveying unit. The defective product removal unit includes multiple independently arranged defective product removal components 21. Each defective product removal component 21 can independently push defective products to the conveying unit, and the conveying unit transports the defective products to the defective product sorting unit.

[0029] The defective product classification unit includes a stop unit 30 and a storage unit 40, which are respectively arranged on opposite sides of the conveying unit. The storage unit 40 includes a defective product storage channel 41, and multiple defective product storage channels 41 are arranged along the defective product conveying direction. Each defective product storage channel 41 is used to store different types of defective products. The stop unit 30 includes a pusher component 31 and a blocking component 32, and multiple blocking components 32 are arranged sequentially at intervals along the defective product conveying direction. Each blocking component 32 can independently intercept defective products at the defective product storage channel corresponding to its category. The pusher component 31 is used to push different types of defective products into the corresponding defective product storage channel 41.

[0030] The battery defective product sorting device provided in this embodiment pushes defective products to a conveying unit via a defective product discharge unit. The conveying unit then transports the defective products to the defective product sorting unit. The defective product sorting unit is equipped with multiple defective product storage channels and multiple independent blocking components. Each defective product storage channel has a corresponding blocking component, enabling individual interception of different categories of defective products. These products are then pushed into their corresponding defective product storage channels by a pushing component, thus achieving precise sorting of different categories of defective products. This battery defective product sorting device can perform batch sorting of defective products, eliminating the need for re-sorting after discharge. This device improves the overall production efficiency of battery cells and can meet the production requirements of an 80PPM production line.

[0031] It should be noted that in this embodiment, the defective products are marked before entering the defective product rejection unit, and the category to which the defective product belongs is marked, such as Hi-pot defective product, housing defective product, tab misalignment defective product, or pressure defective product, etc.

[0032] Based on the above embodiments, as an optional implementation, the conveying unit includes a conveyor belt 10, the conveyor belt 10 including components along a first horizontal direction (i.e., the first direction). Figure 1 The first conveying section 11 is set along the x-axis direction and along the second horizontal direction (i.e., the second direction). Figure 1The second conveying section 12 is positioned along the y-axis direction. The first conveying section 11 and the second conveying section 12 are smoothly connected by an arc segment. The defective product removal unit 20 is located on one side of the first conveying section 11, and the interception unit 30 and the storage unit 40 are located on opposite sides of the second conveying section 12. This L-shaped conveying unit allows for a more compact layout of the components, reducing the floor space occupied by the battery defective product sorting device. In this embodiment, the conveying unit also includes a conveying drive component that drives the conveyor belt 10 to move defective products along the conveying direction. The conveying direction on the first conveying section 11 is a first horizontal direction, and the conveying direction on the second conveying section 12 is a second horizontal direction.

[0033] Based on the above embodiments, as an optional implementation, multiple defective product removal components 21 are arranged sequentially along a first horizontal direction, and each defective product removal component 21 can independently push defective products to the first conveying section 11. Specifically, each defective product removal component 21 includes a first driving member 211 and a first pusher plate 212. The first driving member 211 is connected to the first pusher plate 212, and the first driving member 211 can drive the first pusher plate 212 to move along a second horizontal direction to push the defective products to the first conveying section 11. Thus, by independently arranging each defective product removal component 21, and by allowing each defective product removal component 21 to independently push defective products to the first conveying section 11, it is possible to simultaneously push different types of defective products to the first conveying section 11 according to the arrangement order of the defective product storage channel 41, so as to facilitate the simultaneous pushing of these defective products to the defective product storage channel 41, which is beneficial to further improve the sorting efficiency. As an optional implementation, the first driving member 211 is a cylinder.

[0034] Based on the above embodiments, as an optional implementation, multiple blocking components 32 are arranged sequentially at intervals in the second horizontal direction, and each blocking component 32 can independently intercept defective products at the defective product storage channel 41 corresponding to that defective product category. Specifically, in conjunction with Figure 2As shown, each blocking component 32 includes a second driving member 321 and a stop block 322. The second driving member 321 is connected to the stop block 322. The second driving member 321 can drive the stop block 322 to move along a first horizontal direction, causing the stop block 322 to enter the second conveying section 12 to intercept defective products. This positions the defective products at the defective product storage channel 41 corresponding to their category, preventing them from being conveyed further. Therefore, by intercepting defective products individually through each blocking component 32, not only can defective products be intercepted at the defective product storage channel 41 corresponding to their category, but different categories of defective products can also be intercepted according to the arrangement order of the defective product storage channels 41. This facilitates the simultaneous pushing of these defective products to the defective product storage channel 41 later, further improving the efficiency of sorting. As an optional implementation, the second driving member 321 is a cylinder.

[0035] Based on the above embodiments, as an optional implementation, the interception unit 30 further includes a bracket, with each blocking component 32 disposed on the bracket, and each stop 322 capable of sliding relative to the bracket along a first horizontal direction, allowing the stop 322 to enter the second conveying section 12. Specifically, in conjunction with Figure 3 As shown, each blocking component 32 also includes a slider 323. A slide rail is provided on the bracket along a first horizontal direction. The slider 323 cooperates with the slide rail. A second driving member 321 drives the slider 323 to move on the slide rail. The slider 323 is connected to a stop block 322, thereby causing the stop block 322 to move relative to the bracket 33 along the first horizontal direction. Therefore, the slide rail and slider 323 can more smoothly move the stop block 322 along the first horizontal direction, resulting in better interception of defective products and improving the accuracy of repeated interception.

[0036] Based on the above embodiments, as an optional implementation, the number of blocking components 32 is N, the number of defective product storage channels 41 is N+1, and the connecting portion between any two adjacent defective product storage channels 41 is arranged opposite to the stop block 322, where N is an integer greater than or equal to 1. By having the connecting portion between any two adjacent defective product storage channels 41 arranged opposite to the stop block 322, defective products can be intercepted at the defective product storage channel 41 corresponding to that defective product category, without interfering with the subsequent pushing of defective products into the corresponding defective product storage channel 41. For example, Figure 1 There are 5 blocking components 32 and 6 defective product storage channels 41. The connection between any two adjacent defective product storage channels 41 is set opposite to a block 322.

[0037] Based on the above embodiments, as an optional implementation, a stop plate 121 is provided at the end of the second conveying section 12 away from the first conveying section 11. The stop plate 121 is used to intercept defective products that have not been intercepted by the stop block 322. That is, the stop plate 121 is located near the Nth blocking component 32, which is the blocking component 32 away from the first conveying section 11. The stop plate 121 extends from the side of the second conveying section 12 near the interception unit 30 to the side of the second conveying section 13 near the storage unit 40 to intercept defective products at the tail end of the second conveying section 12 and facilitate the subsequent pushing of defective products at the tail end of the second conveying section 12 to the corresponding defective product storage channel 41.

[0038] Based on the above embodiments, as an optional implementation, the pushing assembly 31 includes a third driving member 311 and a second pushing plate 312. The second pushing plate 312 extends along a second horizontal direction, with its first end corresponding to the first defective product storage channel 41 and its second segment corresponding to the (N+1)th defective product storage channel 41. The first and second ends are the two opposite ends of the second pushing plate 312 along the second horizontal direction; that is, the first end is the head end of the second pushing plate 312, and the second end is the tail end. The third driving member 311 is connected to the second pushing plate 312 and can drive the second pushing plate 312 to move along the first horizontal direction, causing the second pushing plate 312 to enter the second conveying section 13 and push the defective products in the second conveying section 13 to the corresponding defective product storage channel 41. Thus, by setting the second pushing plate 312, multiple defective products intercepted by the blocking components 32 can be simultaneously pushed into the corresponding defective product storage channel 41, which is beneficial to further improve the efficiency of sorting. As an alternative implementation, the third drive component 311 is a cylinder.

[0039] Based on the above embodiments, as an optional implementation, the second pusher plate 312 is mounted on the bracket, and the second pusher plate 312 has multiple notches 3121 through which the stops 323 can pass. The number of notches 3121 is the same as the number of stops 323, and the notches 3121 and stops 323 are arranged in a one-to-one correspondence. Thus, the stops 323 can pass through the notches 3121 and enter the second conveying section 12 to intercept defective products, placing them in the defective product storage channel 41 corresponding to their category. Subsequently, the second pusher plate 312 is driven to push the defective products into the corresponding defective product storage channel 41. This structure of the second pusher plate 312 not only facilitates the simultaneous pushing of multiple defective products into the corresponding defective product storage channel 41, but also reduces the footprint of the second pusher plate 312 and the stops 323, making the battery defective product sorting device more compact.

[0040] Based on the above embodiments, as an optional implementation, a material distribution component 50 is further included. The material distribution component 50 is disposed on one side of the second conveying section 12, and the material distribution component 50 and the stop unit 30 are disposed on the same side of the second conveying section 12. The material distribution component 50 is located between the defective product discharge unit and the stop unit 30. The material distribution component 50 is used to prevent defective products from entering between the stop unit 30 and the storage unit 40, so as to prevent defective products from entering the defective product classification unit for classification. Thus, by setting the material distribution component 50, some defective products with disordered order can be blocked, so that defective products can enter between the stop unit 30 and the storage unit 40 according to the arrangement order of the defective product storage channel 41, so as to realize the simultaneous pushing of multiple defective products into the defective product storage channel 41.

[0041] For example, Figure 1 There are six defective product storage channels 41, which store six different categories of defective products. Along the second horizontal direction, these six defective product storage channels 41 are sequentially named No. 1, No. 2, No. 3, No. 4, No. 5, and No. 6. Channel 1 is located closer to the first conveyor section 11, and channel 6 is located further away from the first conveyor section 11. The defective product removal unit pushes the defective products to the first conveyor section 11, and the defective products enter the first conveyor section 11 in the order of No. 3, No. 1, and No. 2. At this time, these defective products... If the order of the products is not consistent with the arrangement order of the defective product storage channel 41, the material distribution component 50 blocks defective product No. 2. Defective product No. 3 and defective product No. 1 enter the interception unit 30 and storage unit 40 in sequence. The corresponding block 323 intercepts defective product No. 3 at the defective product storage channel 41 and defective product No. 1 at the defective product storage channel 41, respectively. Then, the second push plate 312 pushes the intercepted defective product No. 3 and defective product No. 1 into the corresponding defective product storage channel 41 at the same time.

[0042] Based on the above embodiments, as an optional implementation method, combined with Figure 4As shown, the material distribution assembly 50 includes a fourth drive component 51 and a material distribution disk 52. The fourth drive component 51 is connected to the material distribution disk 52. The fourth drive component 51 can stop the rotation of the material distribution disk 52 to intercept defective products and prevent them from entering between the interception unit 30 and the storage unit 40. Specifically, the material distribution disk 52 has multiple locking notches 521 arranged circumferentially. The multiple locking notches 521 are evenly distributed along the circumference of the material distribution disk 52. Defective products can be accommodated in the locking notches 521. The fourth drive component 51 drives the material distribution disk 52 to rotate, causing each locking notch 521 to rotate around the material distribution disk 52 and assisting the defective products to move along the second conveying section 12. When it is necessary to stop the defective products from moving further, the fourth drive component 51 stops driving the rotation of the material distribution disk 52. At this time, the defective products are locked in a certain locking notch 521, preventing them from moving further. Therefore, the material distribution assembly 50 adopts this structure, which can both intercept defective products with disordered order and not affect the movement of defective products in the second conveying section 12. As an optional implementation, the fourth driving component 51 is a motor.

[0043] The following is combined with Figures 1 to 4 The working principle of the battery cell defect sorting device provided in this embodiment is explained as follows:

[0044] Defective products are conveyed to the defective product removal unit. The defective product removal component 21 pushes the defective products to the first conveying section 11. The first conveying section 11 moves the defective products and conveys them to the second conveying section 12. When the conveying sequence of the defective products is consistent with the arrangement sequence of the defective product storage channel 41, the defective products enter the defective product classification unit. The stop block 323 corresponding to the defective product storage channel 41 intercepts each defective product at its corresponding defective product storage channel 41. The second push plate 312 pushes each intercepted defective product into its corresponding defective product storage channel 41. When the conveying sequence of the defective products is not consistent with the arrangement sequence of the defective product storage channel 41, the sorting tray 52 blocks some defective products with disordered sequence. Other defective products with correct sequence enter the defective product classification unit and are pushed into their corresponding defective product storage channel 41 after being intercepted. Subsequently, the sorting tray 52 releases the defective products with disordered sequence, allowing them to enter the defective product classification unit and be pushed into their corresponding defective product storage channel 41.

[0045] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
