Detailed Implementation

[0049] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0050] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0051] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0052] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0053] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0054] First, it should be noted that the X direction, Y direction, Z direction, above, and below mentioned in the embodiments refer to the attached... Figure 1 and attached Figure 3 The directions mentioned are for illustrative purposes only and are not intended as limitations.

[0055] like Figures 1-16 As shown, an embodiment of this application provides a battery cell sorting device 100, including a conveying mechanism 1 and a lifting and transferring mechanism 2; the conveying mechanism 1 has a first conveyor belt 11 arranged along the X direction, the first conveyor belt 11 being used to transport battery cells in the X direction; the first conveyor belt 11 is capable of passing through the lifting and transferring mechanism 2 in the X direction; the lifting and transferring mechanism 2 is used to lift the battery cells placed on the first conveyor belt 11 in the Z direction and transport them in the Y direction.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, the battery cell sorting device 100 includes a conveying mechanism 1 and a lifting and transferring mechanism 2.

[0057] The conveying mechanism 1 includes a first conveyor belt 11 arranged along the X direction, a second drive assembly 14, a first drive wheel 12 and a second drive wheel 13. The axes of the first drive wheel 12 and the second drive wheel 13 are arranged along the Y direction. The first conveyor belt 11 is wound around the first drive wheel 12 and the second drive wheel 13. The drive end of the second drive assembly 14 is connected to the first drive wheel 12 or the second drive wheel 13, so that the second drive assembly 14 can drive the first conveyor belt 11 to move cyclically along the X direction.

[0058] Furthermore, the second drive component 14 may be a motor, a servo motor, or the like.

[0059] Among them, the lifting and transfer mechanism 2 is a mechanism that can move in the Z direction and transport the battery cell 9 in the Y direction.

[0060] In one embodiment, the lifting and transfer mechanism 2 has two lifting plates that can move in the Z direction, thereby lifting the battery cell 9 located on the first conveyor belt 11.

[0061] In one embodiment, the lifting and transfer mechanism 2 has a clearance cavity 211, the specific structure of which is described below and will not be repeated here.

[0062] In one alternative embodiment, the lifting and transfer mechanism 2 can transport the battery cell 9 to the buffer transport belt via a second conveyor belt 23 that moves in the Y direction.

[0063] In an optional embodiment, the cell sorting device 100 further includes a guide rail arranged along the Y direction, and a lifting and transferring mechanism 2 is slidably connected to the guide rail. The lifting and transferring mechanism 2 moves in the Y direction to transport the cell 9 to the buffer transport belt. Both methods move the cell 9 by translation, which can prevent the cell 9 from being damaged during the movement.

[0064] To further explain, multiple lifting and transferring mechanisms 2 can be set up, spaced apart in the X direction. Each lifting and transferring mechanism 2 corresponds to a buffer conveyor belt, and each buffer conveyor belt corresponds to a specific specification of battery cell 9. When the inspected battery cell 9 is transported on the first conveyor belt 11 to the designated lifting and transferring mechanism 2, and then transported to the buffer conveyor belt by the lifting and transferring mechanism 2, the damage to the battery cell 9 during the sorting process can be reduced. On the other hand, sorting efficiency can be improved, thereby increasing production efficiency.

[0065] In this embodiment, the battery cell sorting device 100 further includes a battery cell rack 3, which is disposed on the first conveyor belt 11; the battery cell rack 3 has a receiving groove 33 for placing battery cells 9; the receiving groove 33 has a channel opening 31 facing the Y direction, and after the battery cell 9 is lifted by the lifting and transfer mechanism 2, it can move away from or into the receiving groove 33 through the channel opening 31.

[0066] like Figure 4 , Figure 5 and Figure 6 As shown, the battery cell sorting device 100 also includes a battery cell holder 3, which is set on the first conveyor belt 11. In other words, the battery cell holder 3 is fixed on the first conveyor belt 11. The battery cell holder 3 can be fixed to the first conveyor belt 11 by means of bolts, rivets, adhesives, etc.

[0067] To further explain, the battery cell rack has a receiving groove 33, which is used to place the battery cell 9. The receiving groove 33 has a channel opening 31 facing the Y direction. The channel opening 31 can be opened at one end, in which case the channel opening 31 will face the direction of the buffer conveyor belt. After the battery cell 9 is lifted from the battery cell rack 3 by the lifting and transfer mechanism 2, it is convenient for the battery cell 9 to leave the receiving groove 33 through the channel opening 31 and be transported to the buffer conveyor belt; or the channel opening 31 can be opened at both ends of the battery cell rack 3, that is, the channel opening 31 is opened on both opposite sides in the Y direction, so that the battery cell 9 can leave the receiving groove 33 through the channel opening 31 and be transported to the buffer conveyor belt; it can also be made so that the two ends of the battery cell 9 in the Y direction can extend out of the receiving groove 33, so that the lifting and transfer mechanism 2 can lift it up. It can also accommodate battery cells 9 of different sizes to improve the compatibility of the battery cell rack 3.

[0068] To further explain, the battery cell holder 3 has limiting plates 32 at both ends along the X direction, thereby forming a receiving groove 33 on the battery cell holder 3 through the two limiting plates 32, in which the battery cell 9 is placed. When the first conveyor belt 11 moves in the X direction, the limiting plates 32 will act as a blocking force to prevent the battery cell 9 from falling off the receiving groove 33 due to inertia.

[0069] In one alternative embodiment, multiple battery cell racks 3 are provided, and the multiple battery cell racks 3 are spaced apart in the X direction, so that multiple battery cells 9 can be transported at the same time to improve sorting efficiency.

[0070] In this embodiment, as Figures 7-10 The first conveyor belt 11 is capable of rotating cyclically around the Y-axis. The first conveyor belt 11 has an upper layer 111 and a lower layer 112. The cell sorting device 100 further includes a fall arrestor 4 and a support member 5. The first end of the fall arrestor 4 is located on the first conveyor belt 11, and the second end of the fall arrestor 4 is located away from the first conveyor belt 11. The support member 5 is located below the first conveyor belt 11. The second end of the fall arrestor 4 can rotate around the Y-axis via the first conveyor belt 11 to the lower layer 112 and abut against the support member 5.

[0071] Specifically, since the first conveyor belt 11 rotates cyclically around the Y-axis, and the battery cell holder 3 has a certain weight, during the circulation process, when the empty battery cell holder 3 is located below the first conveyor belt 11, the first conveyor belt 11 will be pulled down by the battery cell holder 3 under the action of gravity. Over time, the first conveyor belt 11 will be stretched, thus affecting the normal operation of the first conveyor belt 11.

[0072] like Figure 11As shown, the first conveyor belt 11 rotates around the axis in the Y direction, so the first conveyor belt 11 has an upper layer 111 and a lower layer 112. The upper layer 111 and the lower layer 112 refer to the upper layer 111 being above the lower layer 112 in the Z direction. The second end of the fall arrestor 4 of the upper layer 111 of the first conveyor belt 11 is above the first end of the fall arrestor 4, and the second end of the fall arrestor 4 of the lower layer 112 of the first conveyor belt 11 is below the first end of the fall arrestor 4.

[0073] like Figures 7-10 As shown, the cell sorting device 100 also includes a fall arrestor 4 and a support member 5.

[0074] The fall arrestor 4 has a first end and a second end. The first end of the fall arrestor 4 is set on the first conveyor belt 11. In other words, the first end of the fall arrestor 4 is fixed on the first conveyor belt 11. The fall arrestor 4 can be fixed on the first conveyor belt 11 by bolts, rivets, or adhesives.

[0075] For further explanation, please refer to Figure 10 As shown, the support member 5 is located below the first conveyor belt 11, that is, below the lower layer 112 of the first conveyor belt 11. When the first conveyor belt 11 rotates around the Y-axis to the lower layer 112, the second end of the anti-fall bracket 4 is located below the first end of the anti-fall bracket 4 and above the support member 5. When the first conveyor belt 11 is pulled downward by the cell holder 3, the second end of the anti-fall bracket 4 can abut against the support member 5, and the support member 5 can provide support for the anti-fall bracket 4, thereby preventing the first conveyor belt 11 from continuing to fall downward.

[0076] In a preferred embodiment, the second end of the fall arrestor 4 is provided with a roller 41. When the first conveyor belt 11 falls, the roller 41 can slide into contact with the support member 5 to reduce the friction between the fall arrestor 4 and the support member 5 and avoid affecting the rotation of the first conveyor belt 11.

[0077] To further explain, the support member 5 can be a support plate or a cover. The second end of the anti-fall bracket 4 can abut against the bottom end of the cover. The support member 5 is set in the clearance cavity 211 and can be fixed on the conveying mechanism 1. When the lifting and transferring mechanism 2 moves in the Z direction, the first conveyor belt 11 and the support member 5 are relatively stationary, so that the support member 5 provides support force for the first conveyor belt 11.

[0078] To further explain, in the embodiment where multiple battery cell holders 3 are set, the anti-fall bracket 4 is set between two battery cell holders 3, which can provide even support for the first conveyor belt 11 and prevent some parts of the first conveyor belt 11 from being unsupported when it is pulled down by the battery cell holders 3.

[0079] In this embodiment, the height of the fall arrestor 4 is the first height, and the height of the support member 5 from the first conveyor belt 11 is the second height. The first height is less than or equal to the second height.

[0080] The first height refers to the height between the first end and the second end of the fall arrestor 4; the second height refers to the height of the support 5 to the lower layer 112 of the first conveyor belt 11.

[0081] To further explain, the first height is the same as the second height, or the first height is less than the second height, with the difference ranging from 1cm to 10cm. This ensures that when the support 5 abuts against the second end of the fall arrestor 4, the first conveyor belt 11 is not stretched significantly, thus preventing the first conveyor belt 11 from being stretched during prolonged use and affecting its functionality.

[0082] To further explain, the height of the cell holder 3 in the Z direction is the third height, which refers to the height from the upper end to the lower end of the cell holder 3. The first height is greater than the third height to avoid contact between the support 5 and the cell holder 3.

[0083] In this embodiment, Figures 11-16 As shown, the lifting and transfer mechanism 2 includes a housing 21, and the housing 21 has an opening in the clearance cavity 211. The clearance cavity 211 divides the upper end face of the housing 21 into multiple end faces. The lifting and transfer mechanism 2 can move in the Z direction and lift the battery cell 9 located on the first conveyor belt 11 through the end faces. When the lifting and transfer mechanism 2 lifts the battery cell 9, the first conveyor belt 11 can be located in the clearance cavity 211.

[0084] In one embodiment, a clearance cavity 211 is provided inside the housing 21, which divides the upper end face of the housing 21 into two end faces, which are located on both sides of the clearance cavity 21. When the lifting and transfer mechanism 2 moves in the Z direction, it lifts the battery cell 9 located on the first conveyor belt 11 through the two end faces. The battery cell 9 lifted by the lifting and transfer mechanism 2 is located on the upper end face of the lifting and transfer mechanism 2, and the lifting and transfer mechanism 2 can then transport the battery cell 9 to the buffer conveyor belt in the Y direction. In this embodiment, both ends of the battery cell 9 can protrude from the first conveyor belt 11; in an embodiment with a battery cell holder 3, both ends of the battery cell 9 can protrude from both ends of the receiving groove 33, which facilitates lifting the battery cell 9 through the end faces.

[0085] To further explain, the lifting and transferring mechanism 2 includes a housing 21, and the housing 21 has an opening for a clearance cavity 211. Clearance openings are provided on opposite sides of the housing 21 in the X direction, so that the first conveyor belt 11 can extend out of the clearance cavity 211 from one clearance opening and then pass through the clearance opening on the other side. When the lifting and transferring mechanism 2 moves in the Z direction, the clearance cavity 211 can provide a space for the first conveyor belt 11, and can prevent the first conveyor belt 11 from affecting each other when it moves relative to the lifting and transferring mechanism 2.

[0086] In one alternative embodiment, when the first conveyor belt 11 transports the battery cell 9 in the X direction, the first conveyor belt 11 is located above the lifting and transfer mechanism 2 and corresponds to the position of the clearance cavity 211, that is, it is located directly above the clearance cavity 211. When the lifting and transfer mechanism 2 moves upward in the Z direction, the lifting and transfer mechanism 2 can lift the battery cell 9 located on the first conveyor belt 11 and make the first conveyor belt 11 located in the clearance cavity 211. The battery cell lifted by the lifting and transfer mechanism 2 is located on the upper end face of the lifting and transfer mechanism 2, and the lifting and transfer mechanism 2 can then transport the battery cell 9 to the buffer conveyor belt in the Y direction.

[0087] In one alternative implementation, when the first conveyor belt 11 conveys the battery cell 9 in the X direction, the first conveyor belt 11 is located in the clearance cavity 211. When the lifting and transfer mechanism 2 moves upward in the Z direction, the lifting and transfer mechanism 2 can lift the battery cell 9 located on the first conveyor belt 11. The lifting and transfer mechanism 2 transports the battery cell 9 to the buffer conveyor belt in the Y direction.

[0088] In one alternative implementation, such as Figures 13-16 As shown, the clearance cavity 211 includes a first clearance cavity 212 and a second clearance cavity 213, which divide the upper end face of the housing 21 into multiple end faces; two first conveyor belts 11 are provided, one of which is located in the first clearance cavity 212 and the other is located in the second clearance cavity 213; in the Y direction, the end faces are spaced apart from the first conveyor belts 11, and the lifting and transfer mechanism 2 can move in the Z direction and lift the battery cells 9 located on the two first conveyor belts 11 through the end faces.

[0089] To further explain, the clearance cavity 211 includes a first clearance cavity 212 and a second clearance cavity 213, wherein the first clearance cavity 212 and the second clearance cavity 213 are spaced apart in the Y direction. In other words, the first clearance cavity 212 and the second clearance cavity 213 divide the housing 21 into three parts, so the upper end face of the housing 21 forms multiple end faces, namely the first segment 214, the second segment 215 and the third segment 216, which are sequentially the first segment 214, the first clearance cavity 212, the second segment 215 and the second clearance cavity 216 in the Y direction. 3 and the third section 216; A first conveyor belt 11 is provided in the first clearance cavity 212 and a first conveyor belt 11 is provided in the second clearance cavity 213, wherein the battery cell 9 is located on these two first conveyor belts 11. When the lifting and transfer mechanism 2 moves upward, the battery cell 9 is lifted by the first section 214, the second section 215 and the third section 216, and the two first conveyor belts 11 enter the first clearance cavity 212 and the second clearance cavity 213 respectively. Then, the lifting and transfer mechanism 2 transports the battery cell 9 to the buffer conveyor belt.

[0090] The first conveyor belt and the end face may or may not be located on the same plane in the Z direction.

[0091] To further explain, both the battery cell holder 3 and the fall arrestor 4 are mounted on the first conveyor belt 11, which allows the battery cell holder 3 and the fall arrestor 4 to extend out of the clearance cavity 211. When the first conveyor belt 11 moves in the X direction, the battery cell holder 3 and the fall arrestor 4 can move in the gap between the first section 214 and the second section 215 or in the gap between the second section 215 and the third section 216, providing space for the movement of the battery cell holder 3 and the fall arrestor 4 and avoiding any interference between the battery cell holder 3 and the fall arrestor 4 and the lifting and transferring mechanism 2.

[0092] In this embodiment, the lifting and transfer mechanism 2 includes a second conveyor belt 23. The second conveyor belt 23 is partially located on the upper end face of the housing 21 and partially located inside the clearance cavity 211. The second conveyor belt 23 can move along the Y direction on the upper end face of the housing 21.

[0093] like Figures 13-16 As shown, the lifting and transfer mechanism 2 includes a second conveyor belt 23, which is arranged around the upper end face of the housing 21 and the inner wall of the clearance cavity 211, thereby avoiding the opening of the clearance cavity 211 on the upper end face of the housing 21. This will not affect the first conveyor belt 11 entering the clearance cavity 211, nor will it affect the battery cell holder 3 and the anti-fall bracket 4 extending out of the clearance cavity 211.

[0094] In this embodiment, as Figure 16As shown, the housing 21 also includes a plurality of rollers 26 disposed on the inner wall. The rollers 26 are disposed along the X direction and do not interfere with the movement range of the first conveyor belt 11 within the clearance cavity 211. The rollers 26 are used to limit the movement direction of the second conveyor belt 23.

[0095] Specifically, the range of movement of the first conveyor belt 11 in the clearance cavity 211 refers to the position that the first conveyor belt 11 can reach in the clearance cavity 211 when the lifting and transferring mechanism 2 moves in the Z direction.

[0096] In one embodiment, a plurality of rollers 26 are provided on the inner wall of the housing 21, wherein the rollers 26 are rotatable along an axis, and the second conveyor belt 23 is wound around the rollers 26 so that it surrounds the inner wall of the clearance cavity 211 and the upper end face of the housing 21.

[0097] To further explain, such as Figure 16 As shown, the housing also includes two side plates arranged opposite each other in the X direction and a bottom plate connecting the two side plates. Rollers 26 are arranged between the two side plates along the X direction. The upper end face of the housing 21 is composed of rollers 26 arranged along the X direction and close to the upper end of the two side plates and a second conveyor belt 11. When the battery cell 9 is lifted, it can move in the Y direction.

[0098] like Figure 16 As shown, the lifting and transfer mechanism 2 also includes a fourth drive assembly 25, wherein the drive end of the fourth drive assembly 25 is connected to the second conveyor belt 11. The fourth drive assembly 25 can drive the second conveyor belt 23 to rotate, and the second conveyor belt 23 located on the upper surface of the housing 21 can move in the Y direction, so that the battery cell 9 lifted by the lifting and transfer mechanism 2 can be transported to the buffer conveyor belt by moving in the Y direction through the second conveyor belt 23.

[0099] In this embodiment, the lifting and transfer mechanism 2 includes an adjusting member 24, which is disposed on the inner wall of the housing 21 and can move in the Y direction. The second conveyor belt 23 is wound around the adjusting member 24, and the tension of the second conveyor belt 23 is adjusted by moving the adjusting member 24 in the Y direction.

[0100] To further explain, the lifting and transferring mechanism 2 also includes an adjusting member 24, which is disposed on the inner wall of the housing 21 and can move along the Y direction. When the second conveyor belt 23 is too loose or too tight, the tension of the second conveyor belt 23 can be adjusted by the adjusting member 24.

[0101] In this embodiment, the lifting and transfer mechanism 2 includes a first drive component 22, the drive end of the first drive component 22 is connected to the housing 21, and the first drive component 22 drives the housing 21 to move in the Z direction.

[0102] To further explain, the lifting and transfer mechanism 2 also includes a first drive component 22, wherein the drive end of the first drive component 22 is connected to the housing 21, and the first drive component 22 can drive the housing 21 to move in the Z direction, thereby enabling the lifting and transfer mechanism 2 to lift the battery cell 9.

[0103] To further explain, the first drive component 22 can be a hydraulic cylinder, a pneumatic cylinder, or a motor screw, etc.

[0104] In this embodiment, multiple lifting and transfer mechanisms 2 are provided, and the multiple lifting and transfer mechanisms 2 are arranged along the X direction; the cell sorting device 100 also includes a barcode scanning mechanism 6, which corresponds to the position of one of the lifting and transfer mechanisms 2.

[0105] To further explain, the battery cell sorting device 100 also includes a barcode scanning mechanism 6. During battery cell 9 inspection, an information code storing battery cell information is set on the battery cell 9 by the inspection mechanism. When sorting the battery cell 9, the specifications of the battery cell 9 can be determined through the information on the information code. The barcode scanning mechanism 6 scans the information code of the battery cell 9 and then transports the battery cell 9 to the corresponding buffer conveyor belt based on the information.

[0106] To further explain, one of the lifting and transferring mechanisms 2 corresponds to the position of one of the scanning mechanisms 6. The lifting and transferring mechanism 2 can transport the battery cell 9 to the scanning mechanism 6 in the Y direction. The scanning mechanism 6 scans the battery cell 9 to determine the specifications of the battery cell 9.

[0107] In this embodiment, the cell sorting device 100 further includes a blocking mechanism 7 and a frame 8. The blocking mechanism 7 is disposed on the frame 8, and the scanning mechanism 6 is disposed on the blocking mechanism 7. The blocking mechanism 7 is used to limit the distance between the cell 9 located on the lifting and transfer mechanism 2 and the scanning mechanism 6 in the Y direction.

[0108] To further explain, the battery cell sorting device 100 also includes a blocking mechanism 7 and a frame 8. The frame 8 can be a long frame type. The blocking mechanism 7 is set on the frame of the frame 8, the barcode scanning mechanism 6 is set on the blocking mechanism 7, and the lifting and transferring mechanism 2 is set inside the frame 8. When the lifting and transferring mechanism 2 transports the battery cell 9 to the barcode scanning mechanism 6 in the Y direction, the blocking mechanism 7 determines the position of the battery cell 9, so that the battery cell 9 and the barcode scanning mechanism 6 maintain a certain distance, thereby facilitating the barcode scanning mechanism 6 to scan the information code on the battery cell 9.

[0109] The working process of the battery cell sorting device 100 is as follows: First, the feeding mechanism picks up the battery cell 9 from the pallet and places it onto the first conveyor belt 11. The first conveyor belt 11 then transports the battery cell 9 to the battery cell scanning station. Next, the battery cell 9 is lifted off the first conveyor belt 11 by the lifting and transfer mechanism 2 and moved to the scanning mechanism 6. The scanning mechanism 6 scans the battery cell 9 to verify its information. After the battery cell 9 is scanned, the first conveyor belt 11 automatically transports one battery cell 9 to the designated position. Based on the battery cell information, after the battery cell 9 reaches the corresponding specification sorting channel, the corresponding lifting and transfer mechanism 2 automatically transports the battery cell 9 to the buffer conveyor belt. Then, the first conveyor belt 11 automatically transports one battery cell to the designated position. The above steps are repeated to transport multiple battery cells 9 from the battery cell scanning station, and the feeding process continues according to the above steps. The above steps are repeated to perform cyclic sorting of the battery cells 9.
