DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0039] With the maturity and development of battery technology, the application fields of batteries are becoming more and more extensive. In the process of battery production, special equipment is usually required to test the quality of the battery cells. OCV testing (open circuit voltage testing) can detect the size of the electromotive force in the battery and is an important indicator for evaluating battery quality.

[0040] The principle of OCV detection is based on the fact that the potential difference between the positive and negative electrodes of the battery is the open circuit voltage when the battery is in an open circuit state. This voltage value can directly reflect the electrochemical characteristics of the battery, such as the remaining capacity (SOC, State of Charge), health status (SOH, State of Health) and aging degree. In actual testing, a high-precision voltage tester is usually used to measure the open circuit voltage of the battery, and it is ensured that the battery is completely disconnected from the external circuit during the test to avoid the influence of current flow on the measurement results.

[0041] However, in the related art, most of the OCV detection of battery cells is done manually, and automated detection is dedicated to general equipment with poor flexibility. Most of the time, two independent workstations are used for the operation. The OCV automatic detection device cannot adaptively adjust the detection according to different spacings and different models of battery cells.

[0042] In view of this, in order to solve the technical problems of poor flexibility, large floor space, low detection efficiency and detection accuracy of the battery cell detection station, the embodiment of the present application proposes a battery cell detection station, including a first track, a second track and a detection assembly.

[0043] The first track is parallel to the second track and is spaced apart along the first direction; the detection assembly comprises a frame, a code scanning mechanism and a detection mechanism; the code scanning mechanism and the detection mechanism are both arranged on the frame; the frame is slidably arranged on the first track and the second track; wherein the detection mechanism comprises a positive detection probe group and a negative detection probe group; the positive detection probe group and the negative detection probe group are spaced apart along the second direction; the positive detection probe group comprises a plurality of positive detection probes arranged in the first direction; the negative detection probe group comprises a plurality of negative detection probes arranged in the first direction; and the first direction is perpendicular to the second direction.

[0044] In the above scheme, the code scanning mechanism and the detection mechanism are both arranged on the frame, and the code scanning mechanism is integrated with the detection mechanism to realize automated code scanning and detection processes, reduce manual intervention, thereby significantly improving processing speed and work efficiency, and also reducing the floor space of the factory. The frame can be slidably set on the first track and the second track, wherein the detection mechanism includes a positive pole detection probe group and a negative pole detection probe group, which can enable the detection mechanism to automatically detect battery cells adapted to different distances, thereby improving the detection efficiency and detection accuracy of the battery cell detection station.

[0045] For the convenience of description, the following embodiments are described by taking a battery cell detection station according to an embodiment of the present application as an example.

[0046] Please refer to Figures 1 to 5 , Figure 1 A schematic diagram of the structure of a battery cell testing station 100 provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the detection assembly 130 provided in an embodiment of the present application; Figure 3 A schematic diagram of the structure of the detection mechanism 133 provided in the embodiment of the present application; Figure 4 for Figure 3 A top view of Figure 5 This is an enlarged view of the details of the detection mechanism 133 provided in the embodiment of the present application.

[0047] In this embodiment, the battery cell detection station 100 includes a first track 110, a second track 120 and a detection assembly 130. The first track 110 is parallel to the second track 120 and is spaced apart along the first direction X. The detection assembly 130 includes a frame 131, a code scanning mechanism 132 and a detection mechanism 133. The code scanning mechanism 132 and the detection mechanism 133 are both arranged on the frame 131. The frame 131 is slidably arranged on the first track 110 and the second track 120; wherein the detection mechanism 133 includes a positive detection probe group 140 and a negative detection probe group 150. The positive detection probe group 140 and the negative detection probe group 150 are spaced apart along the second direction Y. The positive detection probe group 140 includes a plurality of positive detection probes 141 arranged in the first direction X. The negative detection probe group 150 includes a plurality of negative detection probes 151 arranged in the first direction X. The first direction X is perpendicular to the second direction Y.

[0048] The detection assembly 130 includes a frame 131, a code scanning mechanism 132 and a detection mechanism 133. The code scanning mechanism 132 and the detection mechanism 133 are both arranged on the frame 131, that is, the code scanning mechanism 132 and the detection mechanism 133 are both integrated on the frame 131. Specifically, the code scanning mechanism 132 and the detection mechanism 133 can be fixedly connected through a connecting plate. In the process of manufacturing the battery cell 250, the battery cell 250 is usually provided with an identifiable mark such as a QR code or a barcode for marking the battery cell 250. After the code scanning mechanism 132 marks and positions the battery cell 250 in sequence, the detection mechanism 133 detects the battery cell 250, and then can determine the position of the target battery cell 250 and whether the target battery cell 250 is qualified.

[0049] The frame 131 is slidably disposed on the first track 110 and the second track 120. The frame 131 can move along the length direction of the first track 110 or the second track 120. Since the code scanning mechanism 132 and the detection mechanism 133 are disposed on the frame 131, the code scanning mechanism 132 and the detection mechanism 133 can also move along the length direction of the first track 110 or the second track 120, thereby being able to detect the battery cells 250 at different positions on the tray, so that the detection mechanism 133 can accurately locate the object to be tested, thereby expanding the detection range of the battery cell detection station 100. The code scanning mechanism 132 and the detection mechanism 133 are both disposed on the frame 131, realizing the integration of the detection process, reducing the switching and waiting time between devices, and thus improving the detection efficiency.

[0050] The detection mechanism 133 includes a positive detection probe group 140 and a negative detection probe group 150. The positive detection probe group is used to detect the positive pole of the battery cell 250, and the negative detection probe group 150 is used to detect the negative pole of the battery cell 250. The positive detection probe group 140 and the negative detection probe group 150 are used together to perform a complete OCV test on the battery cell 250.

[0051] Along the second direction Y, the positive pole detection probe group 140 and the negative pole detection probe group 150 are spaced apart, and the distance between the positive pole detection probe group 140 and the negative pole detection probe group 150 is generally the distance between the positive pole of the battery cell 250 and the negative pole of the battery cell 250. The positive pole detection probe group 140 includes a plurality of positive pole detection probes 141 arranged in the first direction X, and the negative pole detection probe group 150 includes a plurality of negative pole detection probes 151 arranged in the first direction X. The plurality of positive pole detection probes 141 and the plurality of negative pole detection probes 151 can simultaneously detect and process the plurality of battery cells 250. Compared with the method of detecting one by one using a single positive pole detection probe 141 and a single negative pole detection probe 151, this design can greatly improve the detection efficiency and detection speed, thereby greatly improving the detection efficiency of the battery cell detection station 100.

[0052] Please refer to Figures 1 to 5 In this embodiment, the detection assembly 130 also includes a first mounting plate 160 and a second mounting plate 170, the positive detection probe group 140 is installed on the first mounting plate 160, and the negative detection probe group 150 is installed on the second mounting plate 170. The first mounting plate 160 and the second mounting plate 170 are both arranged on the frame 131, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0053] The detection assembly 130 also includes a first mounting plate 160 and a second mounting plate 170. The positive detection probe group 140 is arranged on the first mounting plate 160, and the negative detection probe group 150 is arranged on the second mounting plate 170. On the one hand, it can make the structure of the entire detection mechanism 133 clearer, which is conducive to rapid positioning in subsequent maintenance work and reduces maintenance time. On the other hand, during the detection of the battery cell 250, the electromagnetic interference generated by the positive detection probe group 140 and the negative detection probe group 150 may affect the accuracy of the detection results. By installing the two separately, the mutual influence of electromagnetic interference can be reduced and the detection accuracy of the battery cell detection station 100 can be improved.

[0054] Please refer to Figures 1 to 5 In this embodiment, the battery cell inspection station 100 further includes a first driving member 180 , which is disposed on the frame 131 , and output ends of the first driving member 180 are connected to the first mounting plate 160 and the second mounting plate 170 .

[0055] The battery cell inspection station 100 further includes a first driving member 180, which can be, for example, a driving motor. The first driving member 180 is disposed on the frame 131, and the output end of the first driving member 180 is connected to the first mounting plate 160 and the second mounting plate 170, and the first driving member 180 drives the first mounting plate 160 and the second mounting plate 170 to move in the third direction Z. Specifically, the output end of the first driving member 180 can be connected to the first mounting plate 160 and the second mounting plate 170 through a transmission member such as a guide rod or a transmission gear, so as to change the position of the first mounting plate 160 and the second mounting plate 170 in the third direction Z.

[0056] In the actual detection process of the battery cells 250, in the third direction Z, the heights of battery cells 250 of different models will be inconsistent, and the same model of battery cells 250 carried by different trays may also cause the originally set height of the battery cell 250 detection to change. The output ends of the first driving member 180 are connected to the first mounting plate 160 and the second mounting plate 170, which can drive the positive detection probe group 140 and the negative detection probe group 150 to move in the third direction Z, thereby enabling the positive detection probe group 140 and the negative detection probe group 150 to adapt to the actual position of the battery cell 250, greatly improving the detection efficiency and detection speed, thereby greatly improving the detection efficiency of the battery cell detection station 100.

[0057] Specifically, the output ends of the first driving member 180 are connected to the first mounting plate 160 and the second mounting plate 170, and can automatically drive the positive pole detection probe group 140 and the negative pole detection probe group 150, thereby reducing the need for manual intervention, improving the automation level of the detection process, and thereby improving the detection efficiency of the battery cell detection station 100.

[0058] In some embodiments, the detection assembly 130 also includes a first limit member 270, one end of the first limit member 270 is fixed to the frame 131, the first limit member 270 has a plurality of first limit grooves 272, the length direction of the first limit grooves 272 is parallel to the third direction Z, and a first limit pin 271 is fixedly connected to the first guide plate 190, the first limit pin 271 is plugged with any one of the first limit grooves 272, and the first limit pin 271 is inserted into the first limit groove 272, thereby, the movement range of the first limit pin 271 in the third direction Z is the first limit The length range of the groove 272 enables the first limit pin 271 to move within the length range of the first limit groove 272. Since the first limit pin 271 is fixedly connected to the first guide plate 190, the first guide plate 190 can also move within the length range of the first limit groove 272. When the battery cell inspection station 100 fails or other emergencies occur, even if the first guide plate 190 is out of control, it will move within the length range of the first limit groove 272, thereby avoiding damage to the battery cell 250 or other components, thereby improving the safety of the operation of the battery cell inspection station 100.

[0059] Please refer to Figures 1 to 5 In this embodiment, along the first direction X, the positive pole detection probe 141 is movably disposed on the first mounting plate 160 , and the negative pole detection probe 151 is movably disposed on the second mounting plate 170 .

[0060] The positive pole detection probe 141 is movably disposed on the first mounting plate 160, and the negative pole detection probe 151 is movably disposed on the second mounting plate 170, so that the positive pole detection probe 141 and the negative pole detection probe 151 can be adjusted according to the actual size between the positive pole and the negative pole of the battery cell 250, so that the battery cell detection station 100 can adapt to a variety of different models and specifications of battery cells 250, thereby improving the detection flexibility and detection efficiency of the battery cell detection station, and by making the positive pole detection probe 141 and the negative pole detection probe 151 movable, it can also ensure that they are accurately aligned with the positive pole and the negative pole of the battery cell 250, thereby optimizing the detection position and improving the accuracy and reliability of the detection.

[0061] Please refer to Figures 1 to 5 In this embodiment, the detection assembly 130 also includes a first guide plate 190, which is movably disposed on the frame 131 along the third direction Z. A plurality of first guide grooves 191 are disposed on the first guide plate 190, and each positive detection probe 141 is provided with a first pin 141A and cooperates with the corresponding first guide groove 191. The length direction of the first guide groove 191 is inclined relative to the third direction Z. The thickness direction of the first guide plate 190 is parallel to the second direction Y. Along the second direction Y, the relative positive detection probe 141 and the negative detection probe 151 are connected by the first rod 230.

[0062] The detection assembly 130 also includes a first guide plate 190, which is fixed to the frame 131. A plurality of first guide slots 191 are provided on the first guide plate 190. A first pin 141A is provided on each positive detection probe 141. Each first pin 141A is plugged and matched with the corresponding first guide slot 191. The length direction of the first guide slot 191 is inclined relative to the third direction Z, that is, the angle between the axis of the length direction of the first guide slot 191 and the axis of the third direction Z is set at an angle. For example, the angle can be set to 30 degrees, 45 degrees or 60 degrees. When the length direction of the first guide slot 191 is inclined relative to the third direction Z, it can be understood that when the first guide plate 190 moves in the third direction Z, it will drive the first pin 141A plugged and matched with the first guide slot 191 to move in the first direction X. Since the first pin 141A is set on the detection probe, the positive detection probe 141 will also be driven to move in the first direction X.

[0063] The positive detection probe 141 and the negative detection probe 151 are connected through the first rod 230. When the positive detection probe 141 moves in the first direction X, the corresponding negative detection probe 151 will also move in the first direction X. The length direction of the first rod 230 is parallel to the second direction Y. It can be understood that the first rod 230 is on the same horizontal plane, and the relative positive detection probe and negative detection probe 151 can be connected through the first rod 230, so that the positive detection probe 141 and the negative detection probe 151 can be on the same horizontal plane, that is, the height of the first detection probe and the second detection probe can be ensured to be consistent, which can reduce the probability of positional displacement of the positive detection probe 141 and the negative detection probe 151, and improve the detection accuracy of the battery cell detection station 100.

[0064] Specifically, a plurality of first guide grooves 191 are provided on the first guide plate 190, and a first pin 141A is provided on each positive electrode detection probe 141 and cooperates with the corresponding first guide groove 191, so that the positive electrode detection probe 141 and the negative electrode detection probe 151 can be quickly and accurately moved to the specified position, thereby reducing the time of the positive electrode detection probe 141 and the negative electrode detection probe 151, and improving the detection efficiency of the battery cell detection station 100. On the other hand, the positive electrode detection probe 141 and the negative electrode detection probe 151 can also adapt to the detection of battery cells 250 of different sizes and specifications, without the need to replace equipment or perform complex adjustments, further improving the detection efficiency.

[0065] Please refer to Figures 1 to 5 In this embodiment, the length direction of the plurality of first guide grooves 191 is at a different angle to the third direction Z.

[0066] The length direction of the multiple first guide grooves 191 is at a different angle to the third direction Z, and the distance between the positive pole detection probe 141 and the negative pole detection probe 151 can be changed, thereby expanding the detection range of the battery cell detection station 100 and enabling the battery cell detection station 100 to adapt to battery cells 250 of different sizes and specifications.

[0067] A plurality of first guide grooves 191 are provided on the first guide plate 190, and the length direction of each first guide groove 191 can have different angles with the third direction Z, that is, two adjacent first guide grooves 191 are arranged non-parallel. For example, a special angle design can be used to make the distances between two adjacent first guide grooves 191 equal at the same horizontal height along the first direction X, so that when the position of the first guide plate 190 in the third direction Z is adjusted, the distances between the two adjacent positive electrode detection probes 141 and the distances between the two adjacent negative electrode detection probes 151 are equal, thereby improving the detection efficiency and detection accuracy of the battery cell detection station 100.

[0068] In some embodiments, a detection probe 280 is further provided on the positive detection probe 141 and the negative detection probe 151. The detection probe 280 provided on the positive detection probe 141 is used to connect to the positive pole of the battery cell 250, and the detection probe 280 provided on the negative detection probe 151 is used to connect to the negative pole of the battery cell 250. Along the third direction Z, the detection probe 280 of the battery cell 250 is retractable, that is, the length of the detection probe 280 can change with the change of the position of the positive pole and the negative pole of the battery cell 250 in the third direction Z. In this way, the detection probe can adapt to more battery cells 250 of different sizes and specifications, thereby improving the detection efficiency and detection accuracy of the battery cell detection station 100.

[0069] Please refer to Figures 1 to 5 In this embodiment, the detection assembly 130 also includes a second guide plate 210. Along the first direction X, the second guide plate 210 is respectively arranged opposite to the first mounting plate 160 and the second mounting plate 170. Along the third direction Z, the second guide plate 210 is movably arranged on the frame 131. The second guide plate 210 is provided with a second guide groove 211. The first mounting plate 160 is provided with a second pin 160A and cooperates with the second guide groove 211. The length direction of the second guide groove 211 is inclined relative to the third direction Z, and the thickness direction of the second guide plate 210 is parallel to the first direction X.

[0070] The detection assembly 130 includes a second guide plate 210. For example, the second guide plate 210 is movably fixed to the frame 131. The position of the second guide plate 210 is adjustable along the third direction Z. A second guide groove 211 is provided on the second guide plate 210. The position of the second guide groove 211 can also be changed along the third direction Z. A second pin 160A is provided on the first mounting plate 160. The second pin 160A is inserted into the second guide groove 211. The length direction of the second guide groove 211 is inclined to the third direction Z. The thickness direction of the second guide plate 210 is parallel to the first direction X. It can be understood that the second guide plate 210 is perpendicular to the second guide plate or the first guide plate 190. Therefore, the surface where the second guide groove 211 is located is perpendicular to the surface where the first guide groove 191 or the second guide groove is located. The axis of the length direction of the second guide groove 211 is set at an angle to the axis of the third direction Z. For example, the angle between the axis of the length direction of the second guide groove 211 and the axis of the third direction Z can be 30 degrees, 45 degrees or 60 degrees.

[0071] When the position of the second guide plate 210 in the third direction Z changes, the position of the second guide groove 211 in the third direction Z will also change. Since the length direction of the second guide groove 211 is inclined relative to the third direction Z, when the second guide groove 211 moves along the third direction Z, the second pin 160A inserted in the second guide groove 211 will move in the second direction Y, thereby driving the first mounting portion to move in the second direction Y, thereby causing multiple positive pole detection probes 141 to move in the second direction Y. The positive pole detection probe 141 is adaptively adjusted according to the distance between the positive and negative poles of the battery cell 250, so that the battery cell detection station 100 can adapt to the detection of battery cells 250 of different types and sizes, thereby expanding the range of types of battery cells 250 that can be detected by the battery cell detection station 100.

[0072] Please refer to Figures 1 to 5 In this embodiment, the second guide plate 210 also includes a third guide groove 212. The second mounting plate 170 is provided with a third pin 170A and cooperates with the third guide groove 212. The length direction of the third guide groove 212 is inclined relative to the third direction Z.

[0073] When the position of the second guide plate 210 in the third direction Z changes, the position of the third guide groove 212 in the third direction Z will also change. Since the length direction of the third guide groove 212 is inclined relative to the third direction Z, when the third guide groove 212 moves along the third direction Z, the third pin 170A inserted in the third guide groove 212 will move in the second direction Y, thereby driving the second mounting portion to move in the second direction Y, thereby causing multiple negative pole detection probes 151 to move in the second direction Y. The negative pole detection probe 151 is adaptively adjusted according to the distance between the positive and negative poles of the battery cell 250, so that the battery cell detection station 100 can adapt to the detection of battery cells 250 of different types and sizes, thereby expanding the range of types of battery cells 250 that can be detected by the battery cell detection station 100.

[0074] Please refer to Figures 1 to 5 In this embodiment, the angle between the length of the second guide groove 211 and the third direction Z is different from the angle between the third guide groove 212 and the third direction Z, or the inclination direction of the length direction of the second guide groove 211 relative to the third direction Z is different from the inclination direction of the length direction of the third guide groove 212 relative to the fourth direction.

[0075] Exemplarily, the angle of the axis of the length direction of the second guide groove 211 relative to the axis of the third direction Z can be 45 degrees, the angle of the axis of the length direction of the third guide groove 212 relative to the axis of the third direction Z can also be 45 degrees, and the axis of the length direction of the second guide groove 211 and the axis of the length direction of the third guide groove 212 are mirror images. When the positions of the second guide groove 211 and the third guide groove 212 in the third direction Z are changed, the positions of the second pin 160A and the third pin 170A are changed in the second direction Y, thereby driving the first mounting portion and the second mounting portion to move in the second direction Y, and the distance between the multiple positive pole detection probes 141 and the corresponding multiple negative pole detection probes 151 will also change. The positive pole detection probes 141 and the negative pole detection probes 151 can be adaptively adjusted according to the distance between the positive and negative poles of the battery cell 250, so that the battery cell detection station 100 can adapt to the detection of battery cells 250 of different types and sizes, thereby expanding the range of types of battery cells 250 detected by the battery cell detection station 100 and improving the detection efficiency of the battery cell detection station 100.

[0076] Please refer to Figures 1 to 5 In this embodiment, the code scanning mechanism 132 includes a plurality of code scanning cameras 220 , and along the first direction X, the plurality of code scanning cameras 220 are arranged at intervals.

[0077] The code scanning mechanism 132 includes multiple code scanning cameras 220. Exemplarily, the code scanning mechanism 132 may include two code scanning cameras 220. The two code scanning cameras 220 have different scanning angles so as to cover the battery cells 250 in the battery cell inspection station 100, and then scan the QR code of the battery cell 250 to mark and locate each battery cell 250.

[0078] Specifically, the code scanning mechanism 132 includes a plurality of code scanning cameras 220, and the plurality of code scanning cameras 220 are arranged at intervals along the first direction X. On the one hand, the scanning range of the code scanning mechanism 132 can be expanded, so that the battery cell detection station 100 can detect more battery cells 250. On the other hand, the simultaneous operation of the plurality of code scanning cameras 220 can improve the code scanning efficiency, speed up the recognition speed of the barcode of the battery cell 250, reduce the waiting time, improve the overall detection efficiency, and thus improve the detection efficiency of the battery cell detection station 100. Moreover, when one of the code scanning cameras 220 fails or is damaged, the other code scanning camera 220 can continue to operate and continue to scan the battery cells 250 of the battery cell detection station 100, thereby reducing the maintenance and waiting time and improving the operation efficiency of the battery cell detection station 100.

[0079] In some embodiments, the scanning angle of the barcode scanning camera 220 is adjustable, so that the battery cells 250 can be covered in a larger range, allowing the battery cell inspection station 100 to inspect more battery cells 250 .

[0080] In some embodiments, the code scanning mechanism 132 is connected to the frame 131 via a movable guide rail 290 . Along the first direction X, the code scanning mechanism 132 can move along the movable guide rail 290 to scan a wider range of battery cells 250 , thereby expanding the scope of application of the battery cell inspection station 100 .
