Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The core concept of this utility model embodiment lies in disclosing a battery cell sorting device, such as... Figure 1 As shown, the battery cell sorting equipment includes a feeding mechanism 10, a conveying mechanism 20, a base 31, and a robot arm 32, a gripping mechanism 60, a flipping mechanism 40, a first detection mechanism 80 for measuring the thickness of the battery cell, and a second detection mechanism 90 for measuring the voltage and resistance of the battery cell arranged on the base 31. The flipping mechanism 40, the first detection mechanism 80, and the second detection mechanism 90 are arranged in sequence. The feeding mechanism 10 is located on one side of the conveying mechanism 20 and is used to grip the battery cell onto the conveying mechanism 20. The base 31 is located on one side of the conveying mechanism 20, and the robot arm 32 is used to grip the battery cell on the conveying mechanism 20 onto the flipping mechanism 40. The gripping mechanism 60 is respectively arranged corresponding to the first detection mechanism 80 and the second detection mechanism 90 and is used to grip the battery cell onto the first detection mechanism 80 or the second detection mechanism 90.

[0040] In this embodiment of the invention, the conveying mechanism 20 cooperates with the feeding mechanism 10 and the robotic arm 32 on the base 31 to pick up the battery cells and place them on the production line. The gripping mechanism 60 cooperates with the first detection mechanism 80 and the second detection mechanism 90 to perform thickness detection and voltage and resistance detection on the battery cells, respectively. In this embodiment of the invention, automated detection can be achieved, which is highly efficient, safe, requires fewer operators, and has low maintenance costs.

[0041] In this embodiment of the invention, the device can achieve automated operation, effectively improve the stability of cell thickness measurement and voltage and resistance measurement, and is highly efficient, safe, low in investment cost, requires a small workshop area, can be monitored by one operator, and has low maintenance cost.

[0042] In this embodiment of the utility model, the battery cell sorting device includes a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other. Each component in the battery cell sorting device can be arranged along the first direction X, the second direction Y, and the third direction Z, respectively, which can realize the thickness detection, voltage and resistance detection of the battery cells.

[0043] Specifically, the feeding mechanism 10 is a mechanical device that feeds the material or workpiece to be processed to a designated position on the processing equipment. In this embodiment of the utility model, the feeding mechanism 10 is located on one side of the conveying mechanism 20 and is used to grab the battery cell to the conveying mechanism 20.

[0044] Specifically, the conveying mechanism 20 is responsible for the continuous and directional transport of materials to realize the flow of materials between different processes or workstations. The robotic arm 32 can be used to precisely grasp, position, and manipulate materials to complete complex picking and placing tasks. In this embodiment of the present invention, the conveying mechanism 20 is disposed on one side of the base 31, and the robotic arm 32 is arranged on the base 31. The robotic arm 32 and the conveying mechanism 20 cooperate to form a closed loop of material flow in automated production, so that the conveying mechanism 20 can directionally transport the battery cells to the robotic arm 32, and the robotic arm 32 can directionally grasp the battery cells to the flipping mechanism 40.

[0045] Specifically, the robotic arm 32 can be a multi-degree-of-freedom mechanical device. For example, the robotic arm 32 can be a four-axis robotic arm 32, a three-axis robotic arm 32, or a six-axis robotic arm 32. Taking a four-axis robotic arm 32 as an example, the robotic arm 32 includes a drive system, a control system, an end effector, a base 31, and an arm. The drive system is used to drive the end effector. The drive system includes four motors, which, together with ball screws, synchronous belts, and other transmission components, convert the motor power into linear / rotational motion of each axis. The control system consists of a programmable logic controller (PLC) or a dedicated robot controller, which is responsible for receiving instructions such as gripping position and rotation angle, and coordinating the motion sequence of each axis motor. The end effector can be configured according to task requirements. As shown in the figure, the end effector is a third gripper tooling. In other cases, the end effector can also be a vacuum suction cup 431 or a pneumatic finger, etc. The base 31 and the arm provide structural support. The arm is mostly designed with "Cartesian coordinates" (X / Y / Z axes are perpendicular to each other) to ensure the stability of movement and positioning accuracy.

[0046] Specifically, the base 31 can provide support, fixation and stability, and can be used to arrange the robotic arm 32, the flipping mechanism 40, the gripping mechanism 60, the first detection mechanism 80 and the second detection mechanism 90, etc., so that the cooperation between the various structures is more reliable and the structural stability of the battery cell sorting equipment is guaranteed.

[0047] Specifically, the flipping mechanism 40 can be used to flip the battery cell to adjust its orientation, facilitating subsequent inspection of the battery cell. The flipping mechanism 40 can be positioned before the first inspection mechanism 80 and the second inspection mechanism 90, allowing the battery cell to be adjusted before inspection.

[0048] Specifically, the clamping mechanism 60 can be used for directional conveying of battery cells. The clamping mechanism 60 can be respectively set up with the first detection mechanism 80 and the second detection mechanism 90. It can convey the battery cell to the first detection mechanism 80 to complete the thickness detection of the battery cell, or convey the battery cell to the second detection mechanism 90 to complete the voltage and resistance detection of the battery cell.

[0049] Specifically, the flipping mechanism 40, the first detection mechanism 80, and the second detection mechanism 90 can be arranged sequentially. The gripping mechanism 60 can first grip the battery cell to the first detection mechanism 80, and then grip the battery cell to the second detection mechanism 90. Alternatively, the flipping mechanism 40, the second detection mechanism 90, and the first detection mechanism 80 can be arranged sequentially, and the gripping mechanism 60 can also first grip the battery cell to the second detection mechanism, and then grip the battery cell to the first detection mechanism 80. This embodiment of the present invention will be described using one of these methods as an example.

[0050] Optionally, such as Figure 2 As shown, the feeding mechanism 10 includes a feeding frame 11, a first transmission assembly 12, a second transmission assembly 13, a third transmission assembly 14, and a second gripper fixture 15 for gripping battery cells; the first transmission assembly 12 is suspended from the feeding frame 11 and is movably connected to the feeding frame 11 along the first direction X; the second transmission assembly 13 is movably connected to the first transmission assembly 12 along the second direction Y; the third transmission assembly 14 is connected to the second transmission assembly 13 and the second gripper fixture 15 respectively, and the third transmission assembly 14 drives the second gripper fixture 15 to move along the third direction Z; wherein, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0051] In this embodiment of the invention, with the cooperation of the first transmission component 12, the second transmission component 13 and the third transmission component 14, the second gripper can be driven to move along the first direction X, the second direction Y and the third direction Z, so as to adjust the position of the second gripper fixture 15 and reliably grip the battery cell.

[0052] Specifically, the loading rack 11 can serve as the base structure of the loading mechanism 10, and can be used to install and support the first transmission assembly 12, the second transmission assembly 13, the third transmission assembly 14, and the second gripper fixture 15. Typically, the battery cells can be placed in the material frame. As shown in the figure, the loading rack 11 can be erected relatively high. After a tray of material frames is moved to the area below the loading rack 11, the position of the second gripper fixture 15 can be mechanically adjusted to complete the gripping of each material frame, simplifying the operation.

[0053] Specifically, the second gripper fixture 15 can directly grab and hold the material frame. Its specific size and shape can be customized according to the shape of the material frame to ensure the stability, accuracy and efficiency of automated gripping of the material frame.

[0054] Optionally, such as Figure 3 As shown, the second gripper fixture 15 may include a fixture frame 151, a clamping member 152, and a guide member 153. The fixture frame 151 may be the main structure of the second gripper fixture 15. The fixture frame 151 may include a crossbeam and a longitudinal beam to reasonably complete the assembly with the third transmission assembly 14, the clamping member 152, and the guide member 153.

[0055] Specifically, the number of guide members 153 may include at least two, and the at least two guide members 153 may be disposed on opposite sides of the tooling frame 151 in the first direction X. A guide space may be formed between the at least two guide members 153, and the material frame may be embedded into the guide space to complete the pre-fitting of the second gripper tooling 15 and the material frame. The guide members 153 may be fixedly installed to the tooling frame 151, and the installation method may be snap-fit, welding or bolt connection, etc.

[0056] Specifically, the number of clamping members 152 may include at least two, and at least two clamping members 152 may be disposed on opposite sides of the tooling frame 151 in the second direction Y, and a clamping space may be formed between the at least two clamping members 152.

[0057] Optionally, the feeding mechanism 10 may further include an insulating protective plate, which can be connected to the feeding rack 11 and can be used to contact the battery cell to isolate the feeding rack 11 from the battery cell. The clamping member 152 and the guide member 153 can both be designed as insulating components.

[0058] Furthermore, the feeding mechanism 10 also includes a first driving component, which includes a motor or a cylinder. In this way, after the guide 153 guides the material frame into the guide space, the distance between at least two clamping members 152 in the second direction Y can be adjusted by the driving component, so that the clamping members 152 can clamp the material frame to complete the gripping of the material frame by the second gripper tooling 15.

[0059] Optionally, the feeding mechanism 10 may further include a second driving component, which may include a motor or a cylinder. The second driving component may be connected to the tooling frame 151 to drive the tooling frame 151 to rotate about a third direction Z, so as to further improve the reliability of the second gripper tooling 15 in gripping the material frame.

[0060] Specifically, the first transmission assembly 12 may include a first transmission frame, which extends along the second direction Y. Both ends of the first transmission frame can be slidably engaged with the loading frame 11, allowing the first transmission frame to move relatively stably and reliably relative to the loading frame 11 along the first direction X. As shown in the figure, the first transmission assembly 12 includes two first transmission frames, which are spaced apart along the first direction X.

[0061] Furthermore, the loading rack 11 may be provided with a track extending along the first direction X, and the first transmission frame may slide in cooperation with the track on the loading rack 11. Specifically, the driving method of the first transmission frame may be manual adjustment or electric adjustment, etc., and this embodiment of the present invention does not specifically limit this.

[0062] Specifically, the second transmission assembly 13 may include a second transmission frame, which may extend along the first direction X. Both ends of the second transmission frame may be connected to two first transmission frames respectively, and the second transmission frame may slide against the first transmission frames along the second direction Y, allowing the second transmission frame to move relatively stably and reliably relative to the loading rack 11 along the second direction Y. The number of second transmission frames may be one or two, and the two second transmission frames may be spaced apart along the second direction Y.

[0063] Furthermore, the first transmission frame may be provided with a track extending along the second direction Y, and the second transmission frame may slide in cooperation with the track on the first transmission frame. Specifically, the driving method of the second transmission frame may be manual adjustment or electric adjustment, etc., and this embodiment of the present invention does not specifically limit this.

[0064] Specifically, the third transmission assembly 14 may include a movable guide rod and a third drive component. The third drive component includes a motor or a cylinder and can be mounted on the second transmission frame. The third drive component is connected to the movable guide rod and can drive the movable guide rod to move relative to the second transmission frame in a third direction Z. The movable guide rod can be movably connected to the second transmission frame in a third direction Z and can be fixedly connected to the tooling frame 151 of the second gripper tooling 15.

[0065] Optionally, such as Figure 4As shown, the conveying mechanism 20 includes a fixed frame 21, a lifting assembly 22, a conveying guide rail 23, and a recycling guide rail 24; both the conveying guide rail 23 and the recycling guide rail 24 are installed on the fixed frame 21, with the conveying guide rail 23 positioned above the recycling guide rail 24; the lifting assembly 22 is located on one side of the fixed frame 21 and is used to convey the material frame on the conveying guide rail 23 to the recycling guide rail 24.

[0066] In this embodiment of the utility model, the conveying guide rail 23 can be used to convey the material frame storing battery cells. After the battery cells in the material frame are picked up by the robot arm 32, the empty material frame can be conveyed to the recycling guide rail 24 through the lifting component 22 to recycle the empty material frame. This can avoid the empty material frame interfering with the feeding of the material frame storing battery cells and improve the reliability of automated feeding.

[0067] Specifically, the fixed frame 21 is the main structure of the conveying mechanism 20. The fixed frame 21 can be assembled using screws and brackets, and can be arranged on one side of the base 31 for accommodating the lifting assembly 22, the conveying guide rail 23, and the recycling guide rail 24. One end of the conveying guide rail 23 can be correspondingly positioned with the feeding mechanism 10 to improve the reliability of the feeding mechanism 10 in grabbing the material frame onto the conveying guide rail 23; the other end of the fixed frame 21 is correspondingly positioned with the robot arm 32 to facilitate the robot arm 32 in grabbing the battery cells. The conveying guide rail 23 can be a slide rail or a belt, etc.

[0068] Specifically, the conveying mechanism 20 also includes a blocking mechanism, which can be mounted on the fixed frame 21 and positioned close to the base 31. The blocking mechanism can be used to block the material frame, thereby ensuring the reliability of the conveying guide rail 23 in transporting the material frame to the designated position. During the process of using the robotic arm 32 to grasp the battery cells, the blocking mechanism can limit the material frame. After all the battery cells in the material frame have been grasped, the blocking mechanism can move aside to facilitate the transport of the empty frame to the lifting assembly 22. The blocking mechanism may include a lifting cylinder to block the material frame by raising the lifting cylinder. Alternatively, the blocking mechanism may include a lifting cylinder and a limiting plate, so that the lifting cylinder drives the limiting plate to rise, thereby blocking the material frame.

[0069] Specifically, the lifting assembly 22 is located at one end of the conveying guide rail 23 near the robot arm 32 to facilitate the timely recycling of empty material boxes. The lifting assembly 22 may include a lifting platform, on which a belt may be arranged. The lifting platform can move up and down in the third direction Z, and the belt can achieve horizontal transmission, so that the belt can receive empty material boxes and transport them to the recycling guide rail 24.

[0070] Specifically, the recovery guide rail 24 can be arranged on the upper or lower layer of the conveying guide rail 23, and the recovery guide rail 24 can be a slide rail or a belt, etc.

[0071] Optionally, such as Figure 5As shown, the flipping mechanism 40 includes a first drive assembly 41, a mounting base 42, and a rotating assembly 43; the mounting base 42 is mounted on the base 31; the first drive assembly 41 is mounted on the mounting base 42 and connected to the rotating assembly 43 for driving the rotating assembly 43 to rotate; wherein, the robotic arm 32 is used to grasp the battery cell onto the rotating assembly 43.

[0072] In this embodiment of the utility model, the first driving component 41 drives the rotating component 43 to rotate, and the rotating component 43 can drive the battery cell to rotate, thereby realizing the attitude adjustment of the battery cell, which is relatively simple and convenient.

[0073] Specifically, the mounting base 42 is the main structure of the flipping mechanism. The first drive assembly 41 and the rotating assembly 43 are mounted on the mounting base 42, so that the flipping mechanism 40 can be integrated into a single module. By fixing the mounting base 42 to the base 31, the entire flipping mechanism 40 can be installed. In some cases, the first drive assembly 41 can also be directly mounted on the base 31.

[0074] Specifically, the first drive assembly 41 may include a rotary motor or a cylinder, and the first drive assembly 41 also includes components for mounting and fixing the rotary motor or cylinder, which provides power. The rotating assembly 43 may be movably coupled with the mounting base 42 to achieve rotational movement of the rotating assembly 43 relative to the mounting base 42. Specifically, the rotating assembly 43 may drive the battery cell to rotate 90 degrees, and in some cases, the rotating assembly 43 may also drive the battery cell to rotate 270 degrees.

[0075] Optionally, the rotating assembly 43 includes a plurality of suction cups 431 and a first limiting plate 432 and a second limiting plate 433 arranged vertically; the first limiting plate 432 is used to limit and support the battery cell; the plurality of suction cups 431 are mounted on the second limiting plate 433 for adsorbing the battery cell; the first driving assembly 41 is connected to the second limiting plate 433.

[0076] In this embodiment of the invention, the first limiting plate 432 is used to limit and support the battery cell, which can improve the reliability of the robot arm 32 in moving the battery cell to the rotating assembly 43. Since the suction cup 431 is installed on the second limiting plate 433 and the suction cup 431 can attract the battery cell, the second limiting plate 433 can drive the battery cell to rotate, which can improve the reliability of adjusting the battery cell's posture.

[0077] Specifically, the suction cup 431 can grasp and transport the battery cell using the principle of "negative pressure adsorption" or "positive pressure blowing". The suction cup 431 can be fixedly installed on one side of the second limiting plate 433. The number of suction cups 431 can be designed according to actual needs, and this embodiment of the present invention does not impose a specific limitation on this.

[0078] Specifically, the battery cell may include an upper surface, a lower surface, and circumferential sides, with the upper and lower surfaces being the large surfaces of the battery cell. The second limiting plate 433 can be set perpendicularly to the first limiting plate 432, so that when the first limiting plate 432 provides limiting support for the bottom side of the battery cell, the large surface of the battery cell can be adsorbed by the suction cup 431.

[0079] Specifically, as shown in the figure, the battery cell is placed vertically, and the robotic arm 32 can grip the circumferential side of the battery cell. After placing the battery cell on the first limiting plate 432, the large surface of the battery cell can be attracted by the suction cup 431. The first driving component 41 drives the second limiting plate 433 to rotate 90 degrees, so that the battery cell is adjusted to a flat position.

[0080] Optionally, the battery cell sorting equipment further includes a second drive assembly 51, a first guide rail 52, and a barcode scanner 53 for collecting battery cell information; the first guide rail 52 is disposed on the base 31 along the first direction X, the first guide rail 52 is disposed opposite to the barcode scanner 53 along the second direction Y, and the first guide rail 52 is disposed corresponding to the clamping mechanism 60 along the third direction Z; the mounting base 42 is slidably connected to the first guide rail 52 along the first direction X and connected to the second drive assembly 51; wherein the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0081] In this embodiment of the utility model, the mounting base 42 slides along the first direction X, which can drive the battery cell to slide along the first direction X. Since the first guide rail 52 is set opposite to the barcode scanner 53, by adjusting the position of the mounting base 42 in the first direction X, the barcode scanner 53 can scan and identify the battery cell to collect and input data from the battery cell, which facilitates the management and traceability of the battery cell.

[0082] Specifically, barcodes or QR codes can be affixed to the bottom or top side of the battery cell. The barcode scanner 53 can read the encoded information in the barcode or QR code to convert the graphical barcode data into digital / text signals that can be recognized by a computer.

[0083] In some embodiments, the barcode scanner 53 can be fixedly installed on the base 31. By setting the running trajectory of the mounting base 42 in the first direction X, the mounting base 42 can directionally deliver the battery cell to the corresponding position of the barcode scanner 53, ensuring the reliability of the barcode scanner 53 in scanning and identifying the battery cell.

[0084] Specifically, the battery cell sorting equipment also includes a third limiting plate, which can be fixed to one end of the first guide rail 52. The third limiting plate can be set along the first direction X with the mounting base 42. The third limiting plate can be used to block the mounting base 42, so that the mounting base 42 can be moved to a designated position to ensure the convenience of the barcode scanner 53 scanning the battery cell and the reliability of the gripping mechanism 60 gripping the battery cell.

[0085] Specifically, the second drive assembly 51 may include a linear motor or a cylinder to improve the reliability of the drive mounting base 42 moving along the first direction X. The second drive assembly 51 also includes components to assist in mounting the linear motor or cylinder.

[0086] Specifically, the first guide rail 52 is disposed on the base 31 along the first direction X, which can improve the reliability of the mounting base 42 sliding along the first direction X. A slider can be connected to the side of the mounting base 42 facing the guide rail, so that the slider slides into contact with the first guide rail 52. The first guide rail 52 cooperates with the gripping mechanism 60 along the third direction Z, so that the gripping mechanism 60 can grip the battery cell after being adjusted along the third direction Z.

[0087] Optionally, such as Figure 6 As shown, the number of first detection mechanisms 80 includes two, and the two first detection mechanisms 80 are arranged at intervals along the second direction Y; the battery cell sorting equipment also includes a third drive component 71 and a first moving component 72. The first moving component 72 is connected to the third drive component 71, and the first moving component 72 is movably connected to the base 31 along the second direction Y. The first moving component 72 is respectively arranged with the gripping mechanism 60 and the first detection mechanism 80; wherein, the gripping mechanism 60 is used to grip the battery cell to the first moving component 72, and the first moving component 72 is used to transport the battery cell to the first detection mechanism 80 for thickness detection.

[0088] In this embodiment of the utility model, two first detection mechanisms 80 are arranged at intervals along the second direction Y, and the first moving component 72 can move along the second direction Y to cooperate with the two first detection mechanisms 80 respectively. This enables the two first detection mechanisms 80 to perform thickness detection on the battery cell, thereby improving the operating efficiency of the battery cell sorting equipment.

[0089] Specifically, the two first detection mechanisms 80 can be a first sub-detection mechanism and a second sub-detection mechanism, respectively; the first moving component 72 drives the battery cell to move along the second direction Y, which can transport the battery cell to the position corresponding to the first sub-detection mechanism for thickness detection, or transport the battery cell to the position corresponding to the second sub-detection mechanism for thickness detection.

[0090] Specifically, the third drive assembly 71 may include a linear motor or cylinder to drive the first moving assembly 72 to move along the second direction Y. The third drive assembly 71 may also include components for assisting in mounting the linear motor or cylinder.

[0091] Optionally, such as Figure 7As shown, the cell sorting equipment also includes a mounting plate 73 and a second guide rail 74. The mounting plate 73 is mounted on the base 31. The second guide rail 74 is disposed on the mounting plate 73 and extends along the second direction Y. The first moving component 72 includes a first mounting platform 721, a first sensor 722, a second sensor 723, a first limiting structure 724, and a second limiting structure 725. The first mounting platform 721 is slidably connected to the second guide rail 74 along the second direction Y. The first limiting structure 724 and the second limiting structure 725 are spaced apart on the first mounting platform 721 along the second direction Y. The first limiting structure 724 and the second limiting structure 725 are respectively disposed corresponding to the two first detection mechanisms 80. The first sensor 722 is disposed close to the first limiting structure 724, and the second sensor 723 is disposed close to the second limiting structure 725.

[0092] In this embodiment of the invention, both the first limiting structure 724 and the second limiting structure 725 can be used to mount battery cells, allowing the first moving component 72 to carry two battery cells simultaneously. The first sensor 722 can sense the interaction between the first limiting structure 724 and one of the first detection mechanisms 80, thereby improving the reliability of thickness detection of the battery cell via one of the first detection mechanisms 80. Similarly, the second sensor 723 can sense the interaction between the second limiting structure 725 and the other first detection mechanism 80, thereby improving the reliability of thickness detection of the battery cell via the other first detection mechanism 80.

[0093] Specifically, the mounting plate 73 can be used to support the installation of the first movable component 72. The mounting plate 73 can be integrated into the base 31, or the mounting plate 73 can be independent of the base 31. In this embodiment of the present invention, no specific limitation is made.

[0094] Specifically, the second guide rail 74 is disposed on the mounting plate 73 along the second direction Y. The extension length of the second guide rail 74 can be designed according to the distance between the two first detection mechanisms 80, so that the first moving component 72 can move to the position corresponding to the two first detection mechanisms 80 respectively.

[0095] Specifically, the first mounting platform 721 is the main structure of the first moving component 72, used to integrate and mount the first sensor 722, the second sensor 723, the first limiting structure 724, and the second limiting structure 725. The first sensor 722 and the second sensor 723 can be of the same or different types. The first sensor 722 and the second sensor 723 are devices that receive signals or magnetic poles and react, and can convert the measured physical or chemical quantity into another corresponding output. The first sensor 722 can be one of a photoelectric sensor, a distance sensor, a displacement sensor, etc., and the second sensor 723 can be one of a photoelectric sensor, a distance sensor, a displacement sensor, etc.

[0096] Specifically, the first limiting structure 724 and the second limiting structure 725 are used to install and limit the battery cell. The first limiting structure 724 and the second limiting structure 725 can have the same or different shapes. The first limiting structure 724 can be a limiting groove carved in the first mounting platform 721, so that the first limiting structure 724 can be integrated into the first mounting platform 721; or the first limiting structure 724 can be independent of the first mounting platform 721. For example, the first limiting structure 724 can include two limiting blocks arranged opposite each other, and the limiting space between the two limiting blocks forms a limiting space for the battery cell. Similarly, the second limiting structure 725 can be integrated into the first mounting platform 721 or independent of the first mounting platform 721.

[0097] Specifically, a slider may also be connected to the side of the first mounting platform 721 facing the second guide rail 74, so that the slider can slide and engage with the second guide rail 74.

[0098] Specifically, the first limiting structure 724, the first sensor 722, and the first sub-detection mechanism are correspondingly arranged. This allows the first sub-detection mechanism to be activated to detect the thickness of the battery cell on the first limiting structure 724 only after the first sensor 722 detects that the first limiting structure 724 has moved to the position corresponding to the first sub-detection mechanism. Similarly, the second limiting structure 725, the second sensor 723, and the second sub-detection mechanism can be correspondingly arranged. This allows the second sub-detection mechanism to be activated to detect the thickness of the battery cell on the second limiting structure 725 only after the second sensor 723 detects that the second limiting structure 725 has moved to the position corresponding to the second sub-detection mechanism.

[0099] Furthermore, the first moving component 72 can switch between a first position and a second position along the second direction Y. When the first moving component 72 is in the first position, the first limiting structure 724 is close to the first sub-detection mechanism, and the second limiting structure 725 can be correspondingly set with the clamping mechanism 60. In this way, when the first sub-detection mechanism performs thickness detection on the battery cell on the first limiting structure 724, the clamping mechanism 60 can be used to grab a new battery cell to the second limiting structure 725, or to perform unloading processing on the battery cell on the second limiting structure 725. When the first moving component 72 is in the second position, the first limiting structure 724 can be correspondingly set with the clamping mechanism 60, and the second limiting structure 725 is close to the second sub-detection mechanism. In this way, when the second sub-detection mechanism performs thickness detection on the battery cell on the second limiting structure 725, the clamping mechanism 60 can be used to grab a new battery cell to the first limiting structure 724, or to perform unloading processing on the battery cell on the first limiting structure 724. In this embodiment of the invention, the loading and unloading process of the battery cells can be reasonably utilized to achieve uninterrupted thickness detection of the battery cells, thereby improving the working efficiency of the battery cell sorting equipment.

[0100] Optionally, the first detection mechanism 80 includes a mounting frame 81, a pressure member 83 of the sixth drive assembly 82, a pressure sensor 84, and a height sensor 85. The mounting frame 81 is mounted on the mounting plate 73. The pressure member 83 is slidably connected to the mounting frame 81 along the third direction Z and is connected to the sixth drive assembly 82. The third direction Z is perpendicular to the second direction Y. The pressure member 83 is located at one end of the mounting frame 81 away from the second guide rail 74. The pressure sensor 84 and the height sensor 85 are both connected to the pressure member 83.

[0101] In this embodiment of the invention, the mounting bracket 81 is mounted on the mounting plate 73. The first moving component 72 can pass through the mounting bracket 81 during movement, facilitating the delivery of the battery cell to the underside of the pressing member 83 and improving the reliability of battery cell thickness detection. Furthermore, the pressure sensor 84 and height sensor 85, working in conjunction with the pressing member 83, ensure the accuracy of battery cell thickness detection.

[0102] Specifically, the mounting bracket 81 is the main structure of the first detection mechanism 80, used for mounting and cooperating with the base 31, and for supporting the pressure bracket. The mounting bracket 81 may be provided with a third guide rail extending in the third direction Z, and the pressure member 83 may be connected with a slider to slide and cooperate with the third guide rail.

[0103] Specifically, the mounting bracket 81 is clamped onto the mounting plate 73. By moving the first mounting platform 721, the first limiting structure 724 is positioned below the pressing member 83 in the first sub-detection mechanism, or the second limiting structure 725 can be positioned below the pressing bracket in the second sub-detection mechanism.

[0104] Specifically, pressure sensor 84 and height sensor 85 are both types of sensors, which are devices that receive signals or magnetic poles and react accordingly, and can convert the physical or chemical quantity to be measured into another corresponding output.

[0105] Specifically, the sixth drive assembly 82 can be mounted on the mounting bracket 81 or the base 31, etc. The sixth drive assembly includes a lifting motor or cylinder to drive the lowering member 83 to move up and down in the third direction Z. The sixth drive assembly 82 also includes components to assist in mounting the lifting motor or cylinder.

[0106] Optionally, the flipping mechanism 40, the mounting plate 73, and the second detection mechanism 90 are arranged sequentially along the first direction X; the gripping mechanism 60 is disposed between the two first detection mechanisms 80 and installed on one of the first detection mechanisms 80; the gripping mechanism 60 includes a fourth drive component 61, a fifth drive component 62, a second moving component 63, a third moving component 64, and at least one first gripper fixture 65 for gripping the battery cell; the second moving component 63 is movably connected to the first detection mechanism 80 along the first direction X and is connected to the fourth drive component 61; the third moving component 64 is movably connected to the second moving component 63 along the third direction Z and is connected to the fifth drive component 62; the first gripper fixture 65 is connected to the third moving component 64; wherein the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0107] In this embodiment of the invention, with the cooperation of the second moving component 63 and the third moving component 64, the first gripper fixture 65 can move along the first direction X and the third direction Z. Since the flipping mechanism 40, the mounting plate 73, and the second detection mechanism 90 are arranged sequentially along the first direction X, the convenience of the first gripper fixture 65 in gripping the battery cell from the flipping mechanism 40, gripping the battery cell from the first moving component 72, or gripping the battery cell to the second detection mechanism 90 can be improved. This ensures the reliability of performing posture flipping, thickness detection, and voltage and resistance detection on the battery cell, and improves the reliability of the gripping mechanism 60 in transferring the battery cell between various processes.

[0108] Specifically, the clamping mechanism 60 is positioned between the two first detection mechanisms 80, which improves the reliability of the clamping mechanism 60 in loading and unloading battery cells on the first limiting structure 724 and the second limiting structure 725. Installing the clamping mechanism 60 on one of the first detection mechanisms 80 also allows for efficient use of the mounting bracket 81 of the first detection mechanism 80, avoiding the need for a separate mounting bracket 81 for the clamping mechanism 60, and reducing the structural complexity of the battery cell sorting equipment.

[0109] Specifically, the second movable component 63 may include a first movable frame, which can be suspended from the upper end of the mounting frame 81 and movably connected to the mounting frame 81 along the first direction X. The first movable frame can achieve sliding engagement with the mounting frame 81 along the first direction X via a slider guide rail.

[0110] Specifically, the third moving component 64 may include a second moving frame, which can slide and engage with the first moving frame along the third direction Z, and the second moving frame can be connected to the first gripper fixture 65, so that the second moving frame can drive the first gripper fixture 65 to move up and down along the third direction Z.

[0111] Specifically, the third gripper fixture can be a special fixture used to fix and clamp workpieces. In this embodiment of the present invention, the third gripper fixture is used to grip battery cells. The third gripper fixture can be a double-jaw fixture or a three-jaw fixture, etc., and can be a rigid gripper or a flexible gripper, etc., and can be one of a pneumatic gripper, a hydraulic gripper, and an electric gripper, which can be selected according to actual needs.

[0112] Specifically, the number of first gripper fixtures 65 can be one or at least two, and the gripping mechanism 60 may also include a connecting rod, which can be arranged along the first direction X, for mounting and fixing at least two first gripper fixtures 65. The connection method can be screw fixing, snap-fit ​​fixing, or welding fixing, etc. The connecting rod is connected to the second movable frame so that at least two first gripper fixtures 65 can move synchronously.

[0113] Specifically, the fourth drive assembly 61 may include a linear motor or cylinder to drive the second moving assembly 63 to move along the second direction Y. The fourth drive assembly 61 may also include components for assisting in mounting the linear motor or cylinder. Similarly, the fifth drive assembly 62 may include a lifting motor or cylinder to drive the third moving assembly 64 to move up and down along the third direction Z. The fifth drive assembly 62 also includes components for assisting in mounting the lifting motor or cylinder.

[0114] Optionally, the battery cell sorting equipment further includes a first recycling mechanism 33 and a second recycling mechanism 34 installed on the base 31; the first recycling mechanism 33 and the first detection mechanism 80 are arranged side by side along the second direction Y; the clamping mechanism 60 is used to grab the defective battery cells detected by the first detection mechanism 80 and transfer them to the first recycling mechanism 33; the second recycling mechanism 34 and the second detection mechanism 90 are arranged side by side along the second direction Y; the clamping mechanism 60 is used to grab the defective battery cells detected by the second detection mechanism 90 and transfer them to the second recycling mechanism 34.

[0115] In this embodiment of the invention, defective battery cells can be recycled using a first recycling mechanism 33 and a second recycling mechanism 34, which improves the automation of the battery cell sorting equipment. Furthermore, the first recycling mechanism 33 and the second recycling mechanism 34 separately recycle battery cells with thickness defects and those with voltage or resistance defects, facilitating the classification of the battery cells.

[0116] Specifically, such as Figure 8 As shown, the first recycling mechanism 33 can be arranged side by side with the first detection mechanism 80 along the second direction Y, so that the first gripper fixture 65 can move between the first detection mechanism 80 and the first recycling mechanism 33 when it moves along the second direction Y.

[0117] Specifically, the second recycling mechanism 34 can be arranged side by side with the second detection mechanism 90 along the second direction Y, so that the first gripper fixture 65 can move between the second detection mechanism 90 and the second recycling mechanism 34 when it moves along the second direction Y.

[0118] Optionally, such as Figure 9 As shown, both the first recycling mechanism 33 and the second recycling mechanism 34 include a support frame 331, a conveyor belt 332, and a third sensor 333. The support frame 331 is mounted on the base 31 and extends along the second direction Y. The conveyor belt 332 is arranged on the support frame 331 and drives along the second direction Y. The baffle plate 334 is mounted on the end of the support frame 331 away from the clamping mechanism 60, and the baffle plate 334 and the conveyor belt 332 are spaced apart. The third sensor 333 is mounted on the support frame 331 and is located on one side of the conveyor belt 332.

[0119] In this embodiment of the invention, the first recycling mechanism 33 and the second recycling mechanism 34 can have the same structure, which helps to reduce the design difficulty of the battery cell sorting equipment. The baffle plate 334 can limit and block defective battery cells, so that the battery cells are not damaged by falling. The third sensor 333 can sense the coverage area of ​​defective battery cells on the conveyor belt 332. In this way, when a large number of defective battery cells accumulate on the conveyor belt 332, it can remind employees so that they can concentrate on recycling the defective battery cells, which can reduce the workload of employees.

[0120] Specifically, the third sensor 333 belongs to a type of sensor, such as a pressure sensor 84, an ultraviolet sensor, an image sensor, etc., but this embodiment of the present invention does not specifically limit it.

[0121] Specifically, the baffle plate 334 and the conveyor belt 332 are spaced apart to avoid the baffle plate 334 interfering with the transmission of the conveyor belt 332. Along the third direction Z, the gap between the baffle plate 334 and the conveyor belt 332 can be smaller than the thickness of the battery cell to prevent the battery cell from flowing out from the gap between the baffle plate 334 and the conveyor belt 332.

[0122] Specifically, the first recycling mechanism 33 may include a first conveyor belt 332. After the first detection mechanism 80 detects that the cell thickness is unqualified, the first gripper fixture 65 can grab the defective cell onto the first conveyor belt 332, so that the first conveyor belt 332 can transport the defective cell to the recycling point.

[0123] Specifically, the second recycling mechanism 34 may include a second conveyor belt 332. After the second detection mechanism 90 detects that the voltage and resistance of the battery cell are unqualified, the first gripper fixture 65 can grab the defective battery cell onto the second conveyor belt 332, so that the second conveyor belt 332 can transport the defective battery cell to the recycling point.

[0124] Optionally, the number of first gripper fixtures 65 includes four, namely a first sub-gripper fixture 651, a second sub-gripper fixture 652, a third sub-gripper fixture 653, and a fourth sub-gripper fixture 654; the first sub-gripper fixture 651 is correspondingly arranged with the flipping mechanism 40 and is used to grip the flipped battery cell to the first moving component 72; the second sub-gripper fixture 652 is correspondingly arranged with the first moving component 72 and the first recycling mechanism 33, and is used by the user to grip the battery cell from the first moving component 72 to the first recycling mechanism 33; the third sub-gripper fixture 653 is correspondingly arranged with the first moving component 72 and the second detection mechanism 90, respectively, and is used to grip the battery cell from the first moving component 72 to the second detection mechanism 90; the fourth sub-gripper fixture 654 is correspondingly arranged with the second detection mechanism 90 and the second recycling mechanism 34, respectively, and is used to grip the battery cell from the second detection mechanism 90 to the second recycling mechanism 34.

[0125] In the embodiments of this utility model, such as Figure 10 As shown, the first sub-gripper fixture 651 is correspondingly set to the flipping mechanism 40, the second sub-gripper fixture 652 is correspondingly set to the first moving component 72 and the first recycling mechanism 33, the third sub-gripper fixture 653 is correspondingly set to the first moving component 72 and the second detection mechanism 90 respectively, and the fourth sub-gripper fixture 654 is correspondingly set to the second detection mechanism 90 and the second recycling mechanism 34 respectively. Different sub-gripper fixtures can perform different gripping tasks, which can improve the accuracy of gripping on the one hand, and facilitate the simultaneous operation of multiple sub-gripper fixtures on the other hand, thereby improving the working efficiency of the battery cell sorting equipment.

[0126] Specifically, the flipping mechanism 40, the first recycling mechanism 33, the first moving component 72, the second recycling mechanism 34, and the second detection mechanism 90 can be arranged sequentially along the first direction X. When the third moving component 64 moves forward along the second direction Y, the first sub-gripper fixture 651 can pick up the battery cell from the flipping mechanism 40 to the first moving component 72, and the third sub-gripper fixture 653 can pick up the battery cell from the first moving component 72 to the second detection mechanism 90. Alternatively, when the third moving component 64 moves backward along the second direction Y, the second sub-gripper fixture 652 can pick up the battery cell with poor thickness from the first moving component 72 to the first recycling mechanism 33, and the fourth sub-gripper fixture 654 can pick up the battery cell with poor resistance and voltage from the second detection mechanism 90 to the second recycling mechanism 34.

[0127] Specifically, the second mounting platform 91 can be clamped onto the base 31 to raise the positioning structure 95. In this embodiment of the present invention, since the first, second, third, and fourth sub-gripper fixtures 654 move synchronously along the first direction X and the third direction Z, the heights of the flipping mechanism 40, the first recycling mechanism 33, the first moving component 72, the second recycling mechanism 34, and the second detection mechanism 90, as well as the distance between two adjacent components, can be reasonably designed to match the first, second, third, and fourth sub-gripper fixtures 654.

[0128] Optionally, such as Figure 11 As shown, the second detection mechanism 90 includes a second mounting platform 91, a seventh drive assembly 92, a probe assembly 93, and a fourth sensor 94 and a positioning structure 95 arranged on the second mounting platform 91. The second mounting platform 91 and the seventh drive assembly 92 are both mounted on the base 31 and are spaced apart. The positioning structure 95 is located between the fourth sensor 94 and the probe assembly 93. The seventh drive assembly 92 is connected to the probe assembly 93 and is used to drive the probe assembly 93 to move so as to use the probe assembly 93 to detect the resistance and voltage of the battery cell.

[0129] In this embodiment of the present invention, after the fourth sensor 94 detects that the battery cell is fixed on the positioning structure 95, the seventh driving component 92 can drive the probe component 93 to move so as to use the probe component 93 to detect the resistance and voltage of the battery cell, thereby improving the convenience of voltage and resistance detection of the battery cell.

[0130] Specifically, the probe assembly 93 may include a resistance probe and a voltage probe to detect the resistance and voltage of the battery cell respectively, or the probe assembly 93 may include a single probe to detect the resistance and voltage of the battery cell simultaneously.

[0131] Specifically, the seventh drive assembly 92 includes a linear motor or cylinder to drive the probe assembly 93 to move linearly. The seventh drive assembly 92 also includes other components to assist in mounting the linear motor or cylinder. The seventh drive assembly 92 can be mounted on the base 31 or the second mounting platform 91, etc.

[0132] Specifically, the second mounting platform 91 is used to mount the positioning structure 95 and the fourth sensor 94. The positioning structure 95 can be a positioning slot integrated into the second mounting platform 91 for positioning the battery cell; alternatively, the positioning structure 95 can be independent of the second mounting platform 91 and may include multiple positioning blocks that can enclose a positioning space for positioning the battery cell. The fourth sensor 94 is a type of sensor, specifically an ultrasonic sensor, a weighing sensor, an image sensor, or a Hall effect sensor, etc.

[0133] In this embodiment of the invention, the coordinate information of the battery cells can be pre-programmed to set the running trajectory of the battery cells, enabling the various components in the battery cell sorting equipment to cooperate. One working process of the battery cell sorting equipment includes: operating the feeding mechanism 10, adjusting the first transmission component 12, the second transmission component 13, and the third transmission component 14, so that the second gripper fixture 15 can grasp the material frame and move it to the conveying mechanism 20. After the battery cells enter the conveying mechanism 20, the conveying guide rail 23 transports the material frame to the position corresponding to the robot arm 32, and uses a blocking mechanism to limit the material frame. The robot arm 32 grasps the battery cells from the material frame and moves them to the flipping mechanism 40. After placing the battery cells on the first limiting plate 432, the suction cup 431 can attract the battery cells. Then, a rotary motor drives the second limiting plate 433 to rotate, causing the battery cells to rotate from a vertical position to a horizontal position. A linear motor drives the mounting base 42 to slide along the first guide rail 52, causing the mounting base 42 to abut against the third limiting plate. A barcode scanner 53 scans and identifies the battery cell. After the first moving component 72 moves to the designated position, the first sub-gripper fixture 651 grips the battery cell onto the first moving component 72. After the first sub-gripper fixture 651 grips the battery cell, the mounting base 42 can return to its initial position, and the second limiting plate 433 can flip back to its original position, causing the flipping mechanism 40 to reset, so as to perform the operation on the next battery cell. The first mounting table 721 moves along the second direction Y. After the first sensor 722 senses that the first limiting structure 724 is close to the first sub-detection mechanism, the first sub-detection mechanism performs thickness detection on the battery cell on the first limiting structure 724; or, after the second sensor 723 senses that the second limiting structure 725 is close to the second sub-detection mechanism, the second sub-detection mechanism performs thickness detection on the battery cell on the second limiting structure 725. The first or second sub-detection mechanism can upload the measured thickness dimension information to the Manufacturing Execution System (MES system). After thickness detection, the first mounting platform 721 moves in the reverse direction Y. If the battery cell is qualified, the third sub-gripper fixture 653 picks up the qualified battery cell from the first limiting structure 724 or the second limiting structure 725 and transfers it to the second detection mechanism 90. If the battery cell is unqualified, the second sub-gripper fixture 652 picks up the defective battery cell from the first limiting structure 724 or the second limiting structure 725 and transfers it to the first recycling mechanism 33. After the fourth sensor 94 detects that the battery cell is fixed on the positioning structure 95, the probe assembly 93 detects the resistance and voltage of the battery cell. After resistance and voltage detection, if the battery cell is qualified, the next station equipment gripper can be started or the battery cell can be removed manually. If the battery cell is unqualified, the third sub-gripper fixture 653 picks up the defective battery cell from the positioning structure 95 and transfers it to the second recycling mechanism 34. The second detection mechanism 90 can upload the measured thickness information to the MES system.
