Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery sorting device and system. Background Art

[0002] In the process of producing batteries, it is generally necessary to sort the batteries according to the open circuit voltage test results of the batteries, select the unqualified batteries, and proceed to the next step of processing with the qualified batteries. However, in the related art, the efficiency of the battery sorting process is low. Summary of the invention

[0003] The present application provides a battery sorting device and system, which can improve sorting efficiency.

[0004] In the first aspect, the present application provides a battery sorting device, which includes a first power mechanism, a material picking mechanism and an open circuit voltage detection mechanism. The material picking mechanism is arranged at the output end of the first power mechanism to transport the battery driven by the output end of the first power mechanism; the open circuit voltage detection mechanism is used to detect the open circuit voltage of the battery; the open circuit voltage detection mechanism is arranged at the output end of the first power mechanism and is electrically connected to the first power mechanism so that the output end of the first power mechanism moves according to the detection result of the open circuit voltage detection mechanism.

[0005] By arranging the open circuit voltage detection mechanism on the output end of the first power mechanism, the open circuit voltage detection mechanism can be moved to a position close to the battery under the drive of the first power mechanism to perform open circuit voltage detection on the battery. During the detection process, the open circuit voltage detection mechanism can be driven by the output end of the first power mechanism to move synchronously with the material picking mechanism. The detection of the battery by the open circuit voltage detection mechanism will not significantly affect the transportation of the battery by the material picking mechanism. The transportation of the battery by the material picking mechanism and the detection of the open circuit voltage of the battery by the open circuit voltage detection mechanism can be performed synchronously, which is beneficial to improving the sorting efficiency.

[0006] In some implementations of the present application, the open circuit voltage detection mechanism includes a driving member and a detection member. The driving member is disposed on the output end of the first power mechanism; the detection member is disposed on the output end of the driving member so as to be able to move relative to the output end of the first power mechanism under the drive of the output end of the driving member, abut against the electrode terminal of the battery, and detect the open circuit voltage of the battery.

[0007] By driving the output end of the driving member to move relative to the output end of the first power mechanism and abutting against the electrode terminal of the battery to detect the open circuit voltage of the battery, the detection efficiency is relatively high. During the detection process, the battery and the output end of the first power mechanism remain in a relatively fixed state, so that the output end of the driving member drives the detection member to move relative to the output end of the first power mechanism to abut against or separate from the electrode terminal. The abutment and separation of the detection member and the electrode terminal can be achieved more conveniently, which is conducive to improving the detection efficiency.

[0008] In some implementations of the present application, the material picking mechanism includes two opposing clamping arms, at least one of which is movably connected to the output end of the first power mechanism so that the two clamping arms can approach each other along relatively arranged directions to clamp the battery.

[0009] By making the material taking mechanism include two opposite clamping arms, the batteries are clamped by the two clamping arms to transport the batteries, which has a simpler structure, lower cost and higher transport efficiency.

[0010] In some implementations of the present application, the clamping arm extends along the height direction of the battery, and one end is disposed on the output end of the first power mechanism.

[0011] By extending the clamp arm along the height direction of the battery, the stability of the clamp arm in clamping the battery is improved. By arranging one end of the clamp arm on the output end of the first power mechanism, the structure is made more compact and the manufacturing cost is reduced.

[0012] In some implementations of the present application, the driving member is used to drive the detection member to move along the height direction of the battery relative to the output end of the first power mechanism; the output end of the first power mechanism includes a mounting portion, and the mounting portion extends along the arrangement direction of the two clamping arms; the two clamping arms are respectively arranged at both ends of the mounting portion, and the driving member is arranged in the middle of the mounting portion.

[0013] By making the driving member drive the detection member to move along the height direction of the battery relative to the output end of the first power mechanism, the abutment and separation of the detection member and the electrode terminal can be realized more conveniently, which is conducive to improving the detection efficiency. By making the mounting portion extend along the arrangement direction of the two clamping arms; the driving member and the two clamping arms are both arranged on the mounting portion, and the driving member is arranged between the two clamping arms, it is conducive to reducing the space occupied by the open circuit voltage detection mechanism and the clamping arms, and it is also conducive to simplifying the structure of the output end of the first power mechanism and improving the compactness of the structure.

[0014] In some implementations of the present application, the mounting portion extends along the length direction of the battery cell, and there are two detection members, which are a positive electrode detection member and a negative electrode detection member, respectively. The two detection members are arranged along the extension direction of the mounting portion and are both disposed between two clamping arms.

[0015] By extending the mounting portion along the length direction of the battery cell, on the one hand, it is convenient to install the two clamping arms. The two clamping arms are arranged relatively along the length direction of the battery cell, and can clamp the battery cell along the length direction of the battery cell, which is beneficial to improve the stability of the clamping. On the other hand, it is convenient to install the two detection parts arranged along the length direction of the battery cell, which is beneficial to the compact structure of the mounting portion and reduces the cost of processing and manufacturing.

[0016] In some implementations of the present application, there are multiple open circuit voltage detection mechanisms and material picking mechanisms, and they are arranged one by one. The multiple open circuit voltage detection mechanisms and material picking mechanisms are all arranged on the output end of the first power mechanism so that they can move synchronously under the drive of the output end of the first power mechanism.

[0017] By providing a plurality of open circuit voltage detection mechanisms and material taking mechanisms, and enabling them to move synchronously driven by the output end of the first power mechanism, the battery sorting device can sort multiple batteries synchronously, which is beneficial to improving the sorting efficiency.

[0018] In some implementations of the present application, a plurality of material taking mechanisms are arranged along the extension direction of the mounting portion.

[0019] Arranging the multiple material-retrieving mechanisms along the extension direction of the mounting portion is beneficial to reducing the space required for arranging the multiple material-retrieving mechanisms and is beneficial to improving the compactness of the structure.

[0020] In some implementations of the present application, the battery sorting device also includes a code scanning mechanism, which is electrically connected to the first power mechanism and is used to scan the battery so that the output end of the first power mechanism moves according to the scanning result.

[0021] By setting up a code scanning mechanism, the output end of the first power mechanism moves according to the code scanning result, so that the battery sorting device can not only sort according to the detection result of the open circuit voltage, but also sort according to the code scanning result. Both sorting operations can be performed by the battery sorting device. The utilization rate of the battery sorting device is relatively high, which is conducive to reducing costs.

[0022] In some implementations of the present application, the code scanning mechanism is relatively fixed to the fixed end of the first power mechanism.

[0023] The scanning mechanism is relatively fixed to the fixed end of the first power mechanism, which is conducive to reducing costs. The scanning mechanism does not need to be in direct contact with the battery during battery detection, can be set at a position far away from the battery, can be relatively fixed to the fixed end of the first power mechanism, and does not need to be integrated on the output end of the first power mechanism, which is conducive to reducing the complexity of the structure, thereby reducing costs.

[0024] In some implementations of the present application, the battery sorting device also includes a position detector, which is arranged at the output end of the first power mechanism and is used to detect the relative position of the output end of the first power mechanism and the battery; the position detector is electrically connected to the open circuit voltage detection mechanism so that the open circuit voltage detection mechanism detects the battery according to the detection result of the position detector.

[0025] By setting a position detector at the output end of the first power mechanism, the open circuit voltage detection mechanism detects the battery according to the detection result of the position detector, that is, after the position detector outputs that the output end of the first power mechanism and the battery are in a suitable relative position, the open circuit voltage detection mechanism performs detection again, which is beneficial to improving the detection accuracy of the open circuit voltage detection mechanism.

[0026] In a second aspect, the present application provides a battery sorting system, the battery sorting system comprising a conveying mechanism and a battery sorting device provided in the first aspect of the present application. The conveying mechanism is used to convey batteries; the battery sorting device is arranged downstream of the conveying mechanism to convey the batteries on the conveying mechanism.

[0027] The battery sorting system provided by the present application includes the battery sorting device provided by the first aspect of the present application, which can achieve the same effect, that is, can improve the sorting efficiency. The battery sorting device is arranged downstream of the conveying mechanism, and the battery sorting device can sort the batteries sequentially conveyed by the conveying mechanism to the output end of the conveying mechanism, and the sorting efficiency is relatively high.

[0028] In some implementations of the present application, there are multiple battery sorting devices, and the material picking mechanisms of the multiple battery sorting devices are used to move to the output end of the conveying mechanism in sequence to convey the batteries on the conveying mechanism in sequence.

[0029] By making multiple battery sorting devices sort the batteries on the conveying mechanism in turn, after the picking mechanism of one sorting device picks up the batteries from the output end of the conveying mechanism and moves away, the position at the output end of the conveying mechanism is vacated, and the picking mechanism of another sorting device can move to the output end of the conveying mechanism to pick up the batteries, which is conducive to improving the sorting efficiency.

[0030] In some implementations of the present application, the conveying mechanism includes a conveyor line, the conveyor line includes multiple load-bearing parts, and the multiple load-bearing parts are arranged along the extension direction of the conveyor line; the load-bearing part includes a load-bearing sub-part, and the load-bearing sub-part corresponds one-to-one to the batteries; the battery sorting device is used to convey the batteries on each load-bearing part in turn, and the number of material picking mechanisms of the battery sorting device is the same as the number of load-bearing sub-parts of each load-bearing part.

[0031] By using the battery sorting device to sequentially convey the batteries on each carrying portion, the number of the material taking mechanisms of the battery sorting device is the same as the number of the carrying sub-portions of each carrying portion, which is beneficial to improving the sorting efficiency.

[0032] In some implementations of the present application, the battery sorting system also includes a pushing mechanism, which is arranged on a side of the conveyor line away from the battery sorting device along the extension direction of the conveyor line. The pushing mechanism is used to push the battery along the extension direction of the conveyor line so that the battery on the previous load-bearing portion moves to the next load-bearing portion along the extension direction of the conveyor line.

[0033] By providing a pushing mechanism, the pushing mechanism can move the battery on the previous load-bearing part to the next load-bearing part along the extension direction of the conveying line, so that the battery transportation is more convenient and the cost is lower.

[0034] In some implementations of the present application, the number of conveying mechanisms is at least two, and the battery sorting system also includes a second power mechanism, a fixed end of the second power mechanism is relatively fixed to the fixed end of the first power mechanism, and at least two conveying mechanisms are arranged on the output end of the second power mechanism, so as to move in sequence to the positions corresponding to the battery sorting device under the drive of the output end of the second power mechanism.

[0035] There are at least two conveying mechanisms, and the conveying mechanisms can be driven by the output end of the second power mechanism to move to the positions corresponding to the battery sorting device in sequence.

[0036] When the battery sorting device obtains batteries from one conveying mechanism for conveying, the other conveying mechanisms are in an idle state, which is convenient for replenishing. In this way, when the battery sorting system is running, at least one of all the conveying mechanisms contains batteries, and the battery sorting device can always obtain batteries for conveying. The battery sorting system does not need to shut down when the batteries on a conveying mechanism are used up, which is conducive to improving the sorting efficiency.

[0052] Below, this application is described in detail.

[0053] In the process of producing batteries, it is generally necessary to sort the batteries according to the open circuit voltage test results of the batteries, select the unqualified batteries, and proceed to the next step of processing with the qualified batteries. However, in the related art, the efficiency of the battery sorting process is low.

[0054] The reasons for the low efficiency in the battery sorting process are analyzed below, and the analysis process is part of the creativity of this application.

[0055] In the related art, the open circuit voltage detection of the battery and the transportation of the battery by the transportation mechanism are performed sequentially. During the open circuit voltage detection process, the open circuit voltage detection mechanism needs to contact and separate from the battery, which is a relatively slow process. The transportation mechanism needs to wait until the open circuit voltage detection mechanism completes the detection before it can transport the battery, which is inefficient.

[0056] The present application provides a battery sorting device, which includes a first power mechanism, a material picking mechanism and an open circuit voltage detection mechanism. The material picking mechanism is arranged on the output end of the first power mechanism to convey the battery driven by the output end of the first power mechanism; the open circuit voltage detection mechanism is used to detect the open circuit voltage of the battery; the open circuit voltage detection mechanism is arranged on the output end of the first power mechanism and is electrically connected to the first power mechanism so that the output end of the first power mechanism moves according to the detection result of the open circuit voltage detection mechanism. By arranging the open circuit voltage detection mechanism on the output end of the first power mechanism, the open circuit voltage detection mechanism can be driven by the first power mechanism to move to a position close to the battery to detect the open circuit voltage of the battery. During the detection process, the open circuit voltage detection mechanism can be driven by the output end of the first power mechanism to move synchronously with the material picking mechanism. The detection of the battery by the open circuit voltage detection mechanism will not significantly affect the conveying of the battery by the material picking mechanism. The conveying of the battery by the material picking mechanism and the detection of the open circuit voltage of the battery by the open circuit voltage detection mechanism can be carried out synchronously, which is conducive to improving the sorting efficiency.

[0057] The battery sorting device in the present application is used for sorting batteries. According to the detection result of the open circuit voltage detection mechanism, the material picking mechanism transports the batteries that have passed the detection to one place and transports the batteries that have failed the detection to another place.

[0058] The battery in the present application may be of various types, for example, it may be a battery cell, a battery module, a battery pack or an energy storage battery.

[0059] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0060] In the embodiments of the present application, the battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., but the embodiments of the present application are not limited to this.

[0061] In the embodiments of the present application, the battery cells may be cylindrical battery cells, prismatic battery cells, soft-pack battery cells or battery cells of other shapes. Prismatic battery cells include square shell battery cells, blade-shaped battery cells, and polygonal prismatic batteries. Polygonal prismatic batteries may be, for example, hexagonal prismatic batteries, etc. There are no particular limitations in the present application.

[0062] The open circuit voltage detection mechanism in the present application is used to test the open circuit voltage (OCV) of the battery. The open circuit voltage detection is a commonly used method for evaluating the performance of the battery, and can evaluate the charge state, capacity and health of the battery. By testing the open circuit voltage of the battery, the charge and discharge of the battery can be judged, the remaining capacity of the battery can be estimated, and whether the battery has problems such as failure or aging can be detected.

[0063] Below, the embodiments of the present application are described in detail with reference to the accompanying drawings.

[0064] Please refer to Figure 1 and Figure 2 The present application provides a battery sorting device, which includes a first power mechanism 1, a material taking mechanism and an open circuit voltage detection mechanism 3. The material taking mechanism is arranged at the output end of the first power mechanism 1 to convey the battery driven by the output end of the first power mechanism 1; the open circuit voltage detection mechanism 3 is used to detect the open circuit voltage of the battery; the open circuit voltage detection mechanism 3 is arranged at the output end of the first power mechanism 1 and is electrically connected to the first power mechanism 1 so that the output end of the first power mechanism 1 moves according to the detection result of the open circuit voltage detection mechanism 3.

[0065] The first power mechanism 1 in the embodiment of the present application can be implemented in various forms, for example, it can be a robotic arm or a lifting and moving mechanism, etc. The robotic arm can be an articulated robotic arm such as a four-axis robotic arm or a six-axis robotic arm, or a truss robotic arm, etc.

[0066] By arranging the open circuit voltage detection mechanism 3 on the output end of the first power mechanism 1, the open circuit voltage detection mechanism 3 can be moved to a position close to the battery under the drive of the first power mechanism 1 to perform open circuit voltage detection on the battery. During the detection process, the open circuit voltage detection mechanism 3 can be driven by the output end of the first power mechanism 1 to move synchronously with the material picking mechanism. The detection of the battery by the open circuit voltage detection mechanism 3 will not significantly affect the transportation of the battery by the material picking mechanism. The transportation of the battery by the material picking mechanism and the detection of the open circuit voltage of the battery by the open circuit voltage detection mechanism 3 can be performed synchronously, which is beneficial to improving the sorting efficiency.

[0067] In some embodiments of this application, please refer to Figure 1 and Figure 2 The open circuit voltage detection mechanism 3 includes a driving member 31 and a detection member 32. The driving member 31 is arranged on the output end of the first power mechanism 1; the detection member 32 is arranged on the output end of the driving member 31, so that it can move relative to the output end of the first power mechanism 1 under the drive of the output end of the driving member 31, abut against the electrode terminal of the battery, and detect the open circuit voltage of the battery.

[0068] The drive member 31 in the embodiment of the present application can be implemented in various forms, for example, it can be a motor or a power cylinder, etc. The power cylinder can be an oil cylinder or a gas cylinder, etc. In some embodiments of the present application, the drive member 31 can be fixedly connected to the output end of the first power mechanism 1, so that the installation of the drive member 31 on the output end of the first power mechanism 1 is relatively stable.

[0069] By driving the output end of the driving member 31 to move relative to the output end of the first power mechanism 1 and to abut against the electrode terminal of the battery to detect the open circuit voltage of the battery, the detection efficiency is relatively high. During the detection process, the battery and the output end of the first power mechanism 1 remain in a relatively fixed state, so that the output end of the driving member 31 drives the detection member 32 to move relative to the output end of the first power mechanism 1 to abut against or separate from the electrode terminal. The abutment and separation of the detection member 32 and the electrode terminal can be achieved more conveniently, which is conducive to improving the detection efficiency.

[0070] In some embodiments of this application, please refer to Figure 1 and Figure 2 The material-retrieving mechanism includes two opposite clamping arms 2, at least one of which is movably connected to the output end of the first power mechanism 1, so that the two clamping arms 2 can approach each other along oppositely arranged directions to clamp the battery.

[0071] In the embodiment of the present application, the direction in which the two clamping arms 2 are relatively arranged has an angle with the extension direction of the clamping arms 2 , for example, is perpendicular to the extension direction of the clamping arms 2 .

[0072] In the embodiment of the present application, both clamp arms 2 may be movably connected to the output end of the first power mechanism 1 , or one clamp arm 2 may be movably connected to the output end of the first power mechanism 1 and the other clamp arm 2 may be fixed to the output end of the first power mechanism 1 .

[0073] In the embodiment of the present application, there are multiple ways to realize the active connection between the clamp arm 2 and the output end of the first power mechanism 1. For example, the clamp arm 2 can be slidably connected to the output end of the first power mechanism 1 along the direction in which the two clamp arms 2 are relatively arranged, that is, the arrangement direction of the two clamp arms 2, or one end of the clamp arm 2 can be rotationally connected to the output end of the first power mechanism 1, and the axis of the rotational connection is perpendicular to the direction in which the two clamp arms 2 are relatively arranged, so that the other end of the clamp arm 2 can swing relative to the end of the clamp arm 2 that is rotationally connected to the first power structure in a direction close to the other clamp arm 2, so as to clamp the battery together with the other clamp arm 2.

[0074] In the embodiment of the present application, the two clamping arms 2 approach each other along the oppositely set directions to clamp the battery along the oppositely set directions, and the two clamping arms 2 move away from each other along the oppositely set directions to release the battery. When the two clamping arms 2 clamp the battery, the battery and the output end of the first power mechanism 1 are relatively fixed, so that when the output end of the first power mechanism 1 moves, the battery follows the output end of the first power mechanism 1 to achieve battery transportation.

[0075] By making the material taking mechanism include two opposite clamping arms 2, the batteries are clamped by the two clamping arms 2 to transport the batteries, which has a simpler structure, lower cost and higher transport efficiency.

[0076] In some embodiments of this application, please refer to Figure 1 and Figure 2 The clamp arm 2 extends along the height direction a of the battery, and one end is arranged on the output end of the first power mechanism 1.

[0077] By extending the clamp arm 2 along the height direction a of the battery, the stability of the clamp arm 2 in clamping the battery is improved. By arranging one end of the clamp arm 2 on the output end of the first power mechanism 1, the structure is made more compact and the manufacturing cost is reduced.

[0078] In some embodiments of this application, please refer to Figure 1 and Figure 2 The driving member 31 is used to drive the detection member 32 to move along the height direction a of the battery relative to the output end of the first power mechanism 1; the output end of the first power mechanism 1 includes a mounting portion 11, and the mounting portion 11 extends along the arrangement direction of the two clamping arms 2; the two clamping arms 2 are respectively arranged at both ends of the mounting portion 11, and the driving member 31 is arranged in the middle of the mounting portion 11.

[0079] In the embodiment of the present application, the two ends of the mounting portion 11 refer to the two ends of the mounting portion 11 in its own extension direction, and the middle part of the mounting portion 11 refers to the middle part of the mounting portion 11 in its own extension direction.

[0080] By making the driving member 31 used to drive the detection member 32 to move along the height direction a of the battery relative to the output end of the first power mechanism 1, the abutment and separation of the detection member 32 and the electrode terminal can be realized more conveniently, which is beneficial to improving the detection efficiency. By making the mounting portion 11 extend along the arrangement direction of the two clamping arms 2; the driving member 31 and the two clamping arms 2 are both arranged on the mounting portion 11, and the driving member 31 is arranged between the two clamping arms 2, it is beneficial to reduce the space occupied by the open circuit voltage detection mechanism 3 and the clamping arms 2, and it is also beneficial to simplify the structure of the output end of the first power mechanism 1 and improve the compactness of the structure. Moreover, the clamping arms 2 and the open circuit voltage detection mechanism 3 are integrated on the mounting portion, and when a failure occurs, the mounting portion 11 can be replaced, and the replacement process is relatively convenient.

[0081] In some embodiments of this application, please refer to Figure 1 and Figure 2 When the clamp arm 2 clamps the battery, the side of the battery with the electrode terminal is arranged opposite to the mounting portion 11 along the height direction a of the battery, and the driving member 31 is used to drive the detection member 32 to move from the mounting portion 11 to the electrode terminal to abut against the electrode terminal. In this way, the abutment and separation of the detection member 32 and the electrode terminal can be realized more conveniently, which is conducive to improving the detection efficiency.

[0082] In some embodiments of this application, please refer to Figure 1 and Figure 2 The mounting portion 11 extends along the length direction of the battery cell. There are two detection members 32 , which are a positive electrode detection member 32 and a negative electrode detection member 32 . The two detection members 32 are arranged along the extension direction of the mounting portion 11 and are both disposed between the two clamping arms 2 .

[0083] By extending the mounting portion 11 along the length direction of the battery cell, on the one hand, it is convenient to install the two clamping arms 2. The two clamping arms 2 are arranged relatively along the length direction of the battery cell, and can clamp the battery cell along the length direction of the battery cell, which is beneficial to improve the stability of the clamping. On the other hand, it is convenient to install the two detection components 32 arranged along the length direction of the battery cell, which is beneficial to the compact structure of the mounting portion 11 and reduce the cost of processing and manufacturing.

[0084] In some embodiments of this application, please refer to Figure 1 and Figure 2 The positive electrode detection member 32 and the corresponding negative electrode detection member 32 can be arranged on the output end of the same driving member 31, so as to move synchronously under the drive of the output end of the driving member 31. In this way, the structure is relatively simple.

[0085] In some embodiments of this application, please refer to Figure 1 and Figure 2 There are multiple open circuit voltage detection mechanisms 3 and material picking mechanisms, and they are arranged one by one. The multiple open circuit voltage detection mechanisms 3 and material picking mechanisms are all arranged on the output end of the first power mechanism 1 so that they can move synchronously under the drive of the output end of the first power mechanism 1.

[0086] By providing a plurality of open circuit voltage detection mechanisms 3 and material taking mechanisms, and enabling them to move synchronously driven by the output end of the first power mechanism 1, the battery sorting device can sort multiple batteries synchronously, which is beneficial to improving the sorting efficiency.

[0087] In some embodiments of this application, please refer to Figure 1 and Figure 2 , multiple material taking mechanisms are arranged along the extension direction of the mounting portion 11.

[0088] Arranging the multiple material-retrieving mechanisms along the extension direction of the mounting portion 11 is helpful to reduce the space required for arranging the multiple material-retrieving mechanisms, and is helpful to improve the compactness of the structure.

[0089] In some embodiments of this application, please refer to Figure 1 and Figure 2 The output end of the first power mechanism 1 also includes a mounting frame 12, which includes a first connecting arm 121, a second connecting arm 122 and a third connecting arm 123. The extension direction of the first connecting arm 121 and the second connecting arm 122 is the same as the extension direction of the mounting portion 11. There are multiple second connecting arms 122, which are arranged one by one with the material-retrieving mechanism. The multiple second connecting arms 122 are arranged in sequence along the extension direction and are all fixed on the first connecting arm 121. The two ends of each second connecting arm 122 are provided with a third connecting arm 123, which is fixedly connected to one end of the third connecting arm 123. The multiple third connecting arms 123 are arranged in sequence along the extension direction of the first connecting arm 121. The ends of the two third connecting arms 123 connected to the same second connecting arm 122 away from the corresponding second connecting arm 122 are respectively fixed to the two ends of the corresponding mounting portion 11. In this way, the material-retrieving mechanism is stably mounted on the output end of the first power mechanism 1.

[0090] In some embodiments of this application, please refer to Figure 1 and Figure 2 The battery sorting device also includes a code scanning mechanism 5, which is electrically connected to the first power mechanism 1 and is used to scan the battery so that the output end of the first power mechanism 1 moves according to the scanning result.

[0091] By setting up the code scanning mechanism 5, the output end of the first power mechanism 1 moves according to the code scanning result, so that the battery sorting device can not only sort according to the detection result of the open circuit voltage, but also sort according to the code scanning result. Both sorting operations can be performed by the battery sorting device. The utilization rate of the battery sorting device is relatively high, which is conducive to reducing costs.

[0092] In some embodiments of this application, please refer to Figure 1 and Figure 2The code scanning mechanism 5 includes a code scanner 51, which is electrically connected to the first power mechanism 1 and is used to scan the battery. The code scanner 51 can be a digital camera or a charge coupled device (CCD) camera, etc. Scanning the battery can be scanning a QR code or a barcode of the battery to read the assembly number of the battery. If the battery scanning result is qualified, the open circuit voltage detection module detects the battery during the process of the material picking mechanism conveying the battery, so that the material picking mechanism conveys the battery according to the open circuit voltage detection result. If the battery scanning result is unqualified, the open circuit voltage detection step can be skipped during the process of the material picking mechanism conveying the battery, so that the material picking mechanism conveys the battery according to the scanning result.

[0093] In some embodiments of this application, please refer to Figure 1 and Figure 2 The code scanning mechanism 5 is relatively fixed to the fixed end 13 of the first power mechanism.

[0094] The code scanning mechanism 5 is relatively fixed to the fixed end 13 of the first power mechanism, which is conducive to reducing costs. The code scanning mechanism 5 does not need to be in direct contact with the battery during the battery detection process, can be set at a position far away from the battery, can be relatively fixed to the fixed end 13 of the first power mechanism, and does not need to be integrated on the output end of the first power mechanism 1, which is conducive to reducing the complexity of the structure, thereby reducing costs.

[0095] In some embodiments of this application, please refer to Figure 1 and Figure 2 The code scanning mechanism 5 includes a support column 52 and a cross beam 53. The support column 52 extends in a vertical direction d, and one end is supported on the ground. The cross beam 53 extends in a horizontal direction, and the two ends of the two support columns 52 are fixed respectively. The code scanner 51 is fixed on the cross beam 53, and the code scanner 51 is facing downward to detect the battery.

[0096] In some embodiments of this application, please refer to Figure 1 and Figure 2 The battery sorting device also includes a position detector 4, which is arranged on the output end of the first power mechanism 1 and is used to detect the relative position between the output end of the first power mechanism 1 and the battery; the position detector 4 is electrically connected to the open circuit voltage detection mechanism 3 so that the open circuit voltage detection mechanism 3 detects the battery according to the detection result of the position detector 4.

[0097] The position sensor in the embodiment of the present application may be implemented in various forms. For example, it may be a photoelectric sensor, an inductive sensor, a tolerance sensor, an ultrasonic position sensor, and the like.

[0098] By setting a position detector 4 at the output end of the first power mechanism 1, the open circuit voltage detection mechanism 3 detects the battery according to the detection result of the position detector 4, that is, after the position detector 4 outputs that the output end of the first power mechanism 1 and the battery are in a suitable relative position, the open circuit voltage detection mechanism 3 performs detection again, which is beneficial to improve the detection accuracy of the open circuit voltage detection mechanism 3.

[0099] In some embodiments of this application, please refer to Figure 1 and Figure 2 , the position detector 4 can be fixed on the mounting portion 11. In this way, the position detector 4 can be relatively close to the battery, which is convenient for the position detector 4 to detect the battery.

[0100] The embodiment of the present application further provides a battery sorting system, which includes a conveying mechanism 6 and a battery sorting device. The conveying mechanism 6 is used to convey batteries; the battery sorting device is arranged downstream of the conveying mechanism 6 to convey the batteries on the conveying mechanism 6.

The battery sorting device is arranged downstream of the conveying mechanism 6, and the battery sorting device can convey the batteries conveyed to the output end of the conveying mechanism 6 in sequence by the conveying mechanism 6 for sorting, and the sorting efficiency is relatively high.

[0102] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 There are multiple battery sorting devices, and the material taking mechanisms of the multiple battery sorting devices are used to move to the output end of the conveying mechanism 6 in sequence to convey the batteries on the conveying mechanism 6 in sequence.

[0103] By making multiple battery sorting devices sort the batteries on the conveying mechanism 6 in turn, after the material taking mechanism of one sorting device takes the battery from the output end of the conveying mechanism 6 and moves away, the position at the output end of the conveying mechanism 6 is vacated, and the material taking mechanism of another sorting device can move to the output end of the conveying mechanism to take the battery, which is conducive to improving the sorting efficiency.

[0104] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 The conveying mechanism 6 includes a conveying line, which includes a plurality of load-bearing portions 62, and the plurality of load-bearing portions 62 are arranged along the extension direction c of the conveying line; the load-bearing portion 62 includes a load-bearing sub-portion, and the load-bearing sub-portion corresponds one to one with the battery; the battery sorting device is used to sequentially convey the batteries on each load-bearing portion 62, and the number of the material picking mechanisms of the battery sorting device is the same as the number of the load-bearing sub-portions of each load-bearing portion 62.

[0105] In the embodiment of the present application, the material taking mechanism of the battery sorting device is arranged in a one-to-one correspondence with the batteries.

[0106] In the embodiment of the present application, the conveying direction of the conveying mechanism 6 is the extension direction c of the conveying line.

[0107] By using the battery sorting device to sequentially convey the batteries on each carrying portion 62 , the number of the material taking mechanisms of the battery sorting device is the same as the number of the carrying sub-parts of each carrying portion 62 , which is beneficial to improving the sorting efficiency.

[0108] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 The arrangement direction of the multiple bearing sub-parts belonging to the same bearing part 62 is perpendicular to the extension direction c of the conveying line. In this way, the conveying line can convey a large number of batteries, which is conducive to improving the sorting efficiency.

[0109] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 The arrangement direction of the multiple bearing sub-parts belonging to the same bearing part 62 is the same as the arrangement direction of the multiple material taking mechanisms. In this way, it is convenient for the multiple material taking mechanisms to obtain batteries from the corresponding bearing sub-parts, which is conducive to improving the sorting efficiency.

[0110] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 , the extension direction c of the conveyor line is horizontal, which is conducive to making the conveyor line transport batteries more smoothly.

[0111] The conveyor line in the embodiment of the present application can be implemented in various forms, for example, it can be a conveyor belt or a roller, etc. In some embodiments of the present application, the battery sorting system further includes a pushing mechanism, which is arranged on a side of the conveyor line away from the battery sorting device along the extension direction c of the conveyor line, and the pushing mechanism is used to push the battery along the extension direction c of the conveyor line, so that the battery on the previous load-bearing portion 62 moves to the next load-bearing portion 62 along the extension direction c of the conveyor line.

[0112] By providing a pushing mechanism, the pushing mechanism is made to move the battery on the previous carrying portion 62 to the next carrying portion 62 along the extension direction c of the conveying line, so that the conveyance of the battery is more convenient and the cost is lower.

[0113] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4The pushing mechanism can be driven by a synchronous belt, a power cylinder, or a linear motor to push the battery along the extension direction c of the conveyor line. In this way, the processing and manufacturing is more convenient.

[0114] In some embodiments of this application, please refer to Figure 2 , Figure 3 and Figure 4 The number of conveying mechanisms 6 is at least two, and the battery sorting system also includes a second power mechanism, the fixed end of the second power mechanism is relatively fixed to the fixed end 13 of the first power mechanism, and at least two conveying mechanisms 6 are arranged on the output end of the second power mechanism, so as to move to the position corresponding to the battery sorting device in sequence under the drive of the output end of the second power mechanism.

[0115] There are at least two conveying mechanisms 6, and they can move to the positions corresponding to the battery sorting devices in sequence under the drive of the output end of the second power mechanism.

In this way, when the battery sorting system is running, at least one of all the conveying mechanisms 6 can accommodate batteries, the battery sorting device can always obtain batteries for conveying, and the battery sorting system does not need to shut down when the batteries on one conveying mechanism 6 are used up, which is conducive to improving the sorting efficiency.

The bearing portion 62 is supported on the upper end of the support member 61 to enclose an escape space with the bearing portion 62. The battery sorting system also includes a base 7 fixed relatively to the fixed end 13 of the first power mechanism. The lower end of the support member 61 is slidably connected to the base 7 along the conveying direction of the conveying mechanism 6 so as to be able to move to a position corresponding to the battery sorting device, or move away from a position corresponding to the battery sorting device. The sliding connection directions of the plurality of conveying mechanisms 6 and the base 7 are the same. Among the plurality of conveying mechanisms 6, at least one conveying mechanism 6 is aligned with the escape space of another conveying mechanism 6 along the conveying direction of the conveying mechanism 6 so as to be able to move to a position corresponding to the battery sorting device, or move away from a position corresponding to the battery sorting device through the escape space. In this way, at least two conveying mechanisms 6 can be driven by the output end of the second power mechanism to move to a position corresponding to the battery sorting device in sequence, and the processing and manufacturing are relatively convenient.
