[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0053] In this embodiment, the term "and / or" is merely a description of the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0054] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0055] Existing battery defective product sorting devices typically use simple, fixed buffer racks to hold defective products. A robotic arm picks up the defective product and places it on the rack. This approach has the following drawbacks: 1) The buffer racks require manual emptying at regular intervals, resulting in a large workload and potential interruptions to the automated process. 2) It cannot classify defective products; for example, products with high-risk defects cannot be processed promptly. 3) The robotic arm can only process one defective product at a time, preventing parallel operation and resulting in low sorting efficiency.

[0056] Based on the above issues, such as Figure 1 As shown, this embodiment provides a defective product screening device, including a robotic arm unit 3 and a sorting device. The sorting device includes a buffer unit 1, and the robotic arm unit 3 is used to put defective products into the buffer unit 1.

[0057] Specifically, see Figure 1 and Figure 2 The buffer unit 1 includes a feeding mechanism 11 and a stop mechanism 12. The feeding mechanism 11 is provided with at least one defective product buffer channel 110, which is at least partially inclined relative to the horizontal plane. A defective product inlet 1101 is provided at the first end of the defective product buffer channel 110, and a defective product outlet 1102 is provided at the second end. The defective product outlet 1102 is lower than the defective product inlet 1101. In this embodiment, the defective product outlet 1102 is located at the lowest point of the entire defective product buffer channel 110. The stop mechanism 12 is movably connected to the feeding mechanism 11 and has a stop position to block the defective product outlet 1102 and a clearance position to open the defective product outlet 1102.

[0058] The defective product screening device provided in this embodiment can temporarily store a certain amount of defective products by setting a buffer unit 1, and can also clear the buffer unit 1 in a timely manner. When a defective product is detected on the production line, the stop mechanism 12 is positioned to block the defective product outlet 1102, and the defective product is transferred through the defective product inlet 1101 to the inside of the defective product buffer channel 110. Since the defective product buffer channel 110 is at least partially inclined relative to the horizontal plane, and the defective product outlet 1102 is lower than the defective product inlet 1101, the defective product can automatically slide down under its own gravity. The blocking by the stop mechanism 12 can buffer a certain amount of defective products in the defective product buffer channel 110. When the defective product buffer channel 110 is full or nearly full, the stop mechanism 12 can be moved from the stop position to the clearance position relative to the unloading mechanism 11, thereby opening the defective product outlet 1102. The defective products buffered in the defective product buffer channel 110 automatically slide down under gravity and are output through the defective product outlet 1102, eliminating the need to remove defective products one by one and achieving rapid emptying of the buffer unit 1. This defective product screening device can both buffer the screened defective products and quickly empty the buffered defective products. The emptying operation is convenient and quick, reducing labor and operational difficulty, and effectively improving production efficiency.

[0059] For example, the defective product mentioned in this embodiment is a defective battery 200, specifically a defective cylindrical battery.

[0060] See Figure 1 , Figure 2 as well as Figure 3 The feeding mechanism 11 includes a guide assembly 111 and a cover assembly 112 connected to each other. The guide assembly 111 is provided with a flow channel 1111, and the cover assembly 112 covers the opening of the flow channel 1111. The inner wall of the flow channel 1111 and the cover assembly 112 form the aforementioned defective product buffer flow channel 110, making the defective product buffer flow channel 110 an approximately closed structure, preventing defective products from escaping from the opening of the flow channel 1111, and providing precise guidance for the downward slide of defective products within the defective product buffer flow channel 110.

[0061] like Figure 1 and Figure 2As shown, the stop mechanism 12 includes a connecting plate 121 and a stop plate 122. In some embodiments, the connecting plate 121 is rotatably connected to the lower end of the cover plate assembly 112, and the stop plate 122 is connected to the end of the connecting plate 121 away from the cover plate assembly 112, and is set at an angle to the connecting plate 121. In this embodiment, the stop plate 122 and the connecting plate 121 are connected together approximately perpendicularly. The stop mechanism 12 can rotate and switch between a clearance position and a stop position. When the stop mechanism 12 is in the stop position, the connecting plate 121 covers part of the opening of the flow channel groove 1111. At this time, the cover plate assembly 112 and the connecting plate 121 together cover the opening of the flow channel groove 1111 to prevent defective products from flowing out of the defective product buffer flow channel 110. The stop plate 122 is located diagonally below the feeding mechanism 11 to block the defective product outlet 1102 and prevent defective products from sliding out of the defective product buffer flow channel 110. When the stop mechanism 12 is in the avoidance position, the connecting plate 121 is away from the opening of the flow channel 1111, and the stop plate 122 is away from the defective product outlet 1102, so as to open the defective product outlet 1102.

[0062] In other embodiments, the connecting plate 121 can be slidably connected to the cover plate assembly 112 so that the stop mechanism 12 can slide between the avoidance position and the stop position, which can also achieve the sealing and opening of the defective product outlet 1102.

[0063] like Figure 2 As shown, the defective product buffer channel 110 includes a first channel 1103 and a second channel 1104 that are connected to each other. The first channel 1103 extends vertically, and the second channel 1104 is inclined relative to the horizontal plane. A defective product inlet 1101 is provided at the end of the first channel 1103 away from the second channel 1104, and a defective product outlet 1102 is provided at the end of the second channel 1104 away from the first channel 1103. The second channel 1104 extends downward at an inclination away from the first channel 1103, so that defective products slide down under their own weight, which facilitates the buffering of subsequent defective products. After the defective product outlet 1102 is opened, the defective products can be output by their own weight, realizing the rapid emptying of the defective product buffer channel 110.

[0064] The first flow channel 1103 and the second flow channel 1104 are set at an obtuse angle to allow defective products to slide smoothly from the first flow channel 1103 to the second flow channel 1104. For example, the included angle between the first flow channel 1103 and the second flow channel 1104 is 100° to 150° to ensure the defective products slide smoothly and to avoid excessive impact on the stop plate 122 due to an excessively large angle. For example, the included angle between the first flow channel 1103 and the second flow channel 1104 can be 100°, 110°, 120°, 130°, 140°, 150°, etc., but is not limited to the specific angle values ​​and ranges listed.

[0065] Specifically, such as Figure 3 As shown, the flow channel 1111 includes a vertical channel segment 1111a and an inclined channel segment 1111b that are connected to each other. The vertical channel segment 1111a extends vertically, and the inclined channel segment 1111b is inclined relative to the horizontal plane. Correspondingly, the cover plate assembly 112 includes a first cover plate 1121 and a second cover plate 1122 that are arranged at an angle. The first cover plate 1121 covers the opening of the vertical channel segment 1111a to form a first flow channel 1103 with the inner wall of the vertical channel segment 1111a, and the second cover plate 1122 covers the opening of the inclined channel segment 1111b to form a second flow channel 1104 with the inner wall of the inclined channel segment 1111b.

[0066] For example, the first cover plate 1121 and the second cover plate 1122 can be fixedly connected to the material guide assembly 111 by fasteners such as screws and rivets.

[0067] In this embodiment, see Figure 1 The defective product screening device also includes a detection unit 2, which can detect whether defective products are passing through and / or detect the material level in the defective product buffer channel 110. By detecting the material level, the defective product buffer channel 110 can be emptied in a timely manner when it is full or about to be full. See also Figure 3 and Figure 4 The detection unit 2 includes a signal transmitter 21 and a signal receiver 22. The signal transmitter 21 is used to transmit signals, and the signal receiver 22 is used to receive signals transmitted by the signal transmitter 21. A detection channel 113 is provided through the feeding mechanism 11, which is connected to the defective product buffer channel 110. The signal transmitted by the signal transmitter 21 can be transmitted to the signal receiver 22 through the detection channel 113 and the defective product buffer channel 110. When the signal receiver 22 receives the signal transmitted by the signal transmitter 21, it indicates that there is no obstruction between the two, no defective products are passing through, and the material level has not reached the location of the detection unit 2. When the signal receiver 22 does not receive the signal transmitted by the signal transmitter 21, it indicates that there is an obstruction between the two, at which time defective products are passing through or the material level in the defective product buffer channel has reached the location of the detection unit 2, and the operator is promptly reminded to empty the defective product buffer channel 110.

[0068] In some embodiments, the signal transmitter 21 is an optical fiber transmitter and the signal receiver 22 is an optical fiber receiver.

[0069] In some embodiments, the signal transmitter 21 is an infrared transmitter and the signal receiver 22 is an infrared receiver.

[0070] In this embodiment, as Figure 1 and Figure 5As shown, the defective product screening device also includes a power unit 4, and at least two buffer units 1 are provided along the first direction. The power unit 4 is connected to the buffer unit 1 and is used to drive the buffer unit 1 to move along the first direction. The robotic arm unit 3 includes a fixed frame 34 and a first drive mechanism 31, a second drive mechanism 32, and a clamping mechanism 33 connected in sequence. Specifically, the housing of the first drive mechanism 31 is connected to the fixed frame 34, the output end of the first drive mechanism 31 is connected to the housing of the second drive mechanism 32, the output end of the second drive mechanism 32 is connected to the housing of the clamping mechanism 33, and the output end of the clamping mechanism 33 is used to clamp defective products. The first drive mechanism 31 is used to drive the second drive mechanism 32 to move along the second direction, the second drive mechanism 32 is used to drive the clamping mechanism 33 to move along the third direction, and the clamping mechanism 33 is used to selectively release defective products into the defective product inlet 1101 of any buffer unit 1 under the drive of the first drive mechanism 31 and the second drive mechanism 32. The first direction, the second direction, and the third direction are perpendicular to each other, the first direction and the second direction are both horizontal, and the third direction is vertical. Driven by the power unit 4, the buffer unit 1 can move to directly below the clamping mechanism 33 to receive the defective products held by the clamping mechanism 33 through the defective product inlet 1101 and guide the defective products into the defective product buffer channel 110. Specifically... Figure 1 and Figure 5 In the diagram, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction.

[0071] Any one of the buffer units 1 can be directly opposite the clamping mechanism 33 under the drive of the power unit 4 to receive defective products. By setting at least two buffer units 1, defective products can be classified and buffered to achieve the sorting of defective products. For example, the defective product buffer channel 110 of one of the buffer units 1 can be specially used to store defective products with high-risk defects, so that defective products with high-risk defects can be processed in a timely manner.

[0072] For example, the first drive mechanism 31, the second drive mechanism 32, and the power unit 4 can all be linear drive mechanisms such as cylinders, hydraulic cylinders, electric push rods, and linear modules. The clamping mechanism 33 is a gripper cylinder. When the defective product is a defective cylindrical battery, the gripper of the gripper cylinder is adapted to the shape of the outer wall of the cylindrical battery.

[0073] like Figure 1 and Figure 4As shown, the defective product screening device also includes a base 5, a support frame 6, a first buffer 7, and a second buffer 8. The housing of the power unit 4 is mounted on the base 5, and the output end of the power unit 4 is connected to the first end of the support frame 6. Multiple buffer units 1 are disposed at the second end of the support frame 6. The support frame 6 can slide along the base 5 under the drive of the power unit 4. The first buffer 7 and the second buffer 8 are both connected to the base 5 and are respectively disposed on both sides of the support frame 6 along the first direction. The first buffer 7 and the second buffer 8 abut against or separate from the support frame 6, and are used to buffer and limit the movement of the support frame 6 to prevent the support frame 6 from colliding hard with the base 5.

[0074] For example, two buffer units 1 are mounted on the support frame 6, and the support frame 6 and the buffer units 1 move between a first limit position and a second limit position. Specifically, when the support frame 6 moves to the first limit position, it abuts against the first buffer 7 and separates from the second buffer 8, with the defective product inlet 1101 of one of the buffer units 1 located directly below the clamping mechanism 33. When the support frame 6 moves to the second limit position, it abuts against the second buffer 8 and separates from the first buffer 7, with the defective product inlet 1101 of the other buffer unit 1 located directly below the clamping mechanism 33.

[0075] One of the two buffer units 1 can be dedicated to storing defective products with high-risk defects, see [reference]. Figure 4 Both buffer units 1 have a detection channel 113 on their material guiding components 111, and the detection channels 113 of the two buffer units are linearly connected. The signal transmitter 21 and the signal receiver 22 are mounted on the support frame 6 and are located on the opposite side of the two buffer units 1. The axis of the detection channel 113 is perpendicular to the extension direction of the second flow channel 1104. The signal emitted by the signal transmitter 21 can pass through the detection channels 113 of the two buffer units 1 and the defective product buffer flow channel 110 and enter the signal receiver 22, so that the signal receiver 22 can receive the signal.

[0076] like Figure 2 and Figure 3 As shown, a first guide rail 51 is provided on the base 5, and the first guide rail 51 extends along the first direction. A first slider 61 is connected to the support frame 6. The first slider 61 and the first guide rail 51 slide in the first direction to guide the movement of the support frame 6 and the buffer unit 1 along the X direction, so as to ensure the movement accuracy and stability and avoid the deviation during movement, which would prevent the defective products from being released smoothly into the defective product inlet 1101.

[0077] like Figure 5As shown, the robotic arm unit 3 also includes a first mounting bracket 35 and a second mounting bracket 36. The first mounting bracket 35 is connected to the output end of the first drive mechanism 31, and the housing of the second drive mechanism 32 is mounted on the first mounting bracket 35. A second guide rail 37 is provided on the fixed carrier 34, extending along the Y direction. A second slider is provided on the first mounting bracket 35, slidingly engaging with the second guide rail 37 along the Y direction to guide the movement of the second drive mechanism 32 along the Y direction. The second mounting bracket 36 is connected to the output end of the second drive mechanism 32, and the housing of the clamping mechanism 33 is connected to the second mounting bracket 36. A third guide rail 38 is provided on the first mounting bracket 35, extending along the Z direction. A third slider is connected to the second mounting bracket 36, slidingly engaging with the third guide rail 38 along the Z direction to guide the movement of the clamping mechanism 33 along the Z direction.

[0078] In this embodiment, see Figure 5 The robotic arm unit 3 includes multiple clamping mechanisms 33. Each buffer unit 1 is provided with multiple defective product buffer channels 110. The multiple defective product buffer channels 110 on each buffer unit 1 correspond one-to-one with the multiple clamping mechanisms 33, so that the multiple defective product buffer channels 110 can receive the defective products clamped by the multiple clamping mechanisms 33, thereby speeding up the processing speed of defective products and accelerating the production cycle.

[0079] This embodiment also provides a battery production line, see [link / reference] Figure 1 and Figure 5 It includes a stage unit 100 and a defective product screening device as described above. The stage unit 100 is used to place the battery 200, and the defective product buffer channel 110 of the defective product screening device is used to buffer defective products of the battery 200. More specifically, the defective products are defective cylindrical batteries.

[0080] The battery production line equipped with this defective product screening device can classify and buffer defective batteries 200. For example, high-risk defective products can be buffered in the same buffer unit 1 for timely processing. Furthermore, by dynamically switching the position of the stop mechanism 12, the buffer unit 1 can achieve both buffering and rapid emptying functions. Additionally, the robotic arm unit 3 can hold at least two defective products at a time, enabling parallel operation and improving the sorting efficiency of defective products. By adopting this defective product screening device, the battery production line can reduce the labor cost of defective product handling to below 5% of the total cost and reduce equipment downtime to ≤2%.

[0081] The platform unit 100 includes a base, on which a fixed clamping block 101 and a movable clamping block 102 are provided. The movable clamping block 102 is connected to the base by an elastic element such as a spring, so that the movable clamping block 102 and the fixed clamping block 101 together clamp the battery 200 under the elastic force of the elastic element.
