[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0050] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0051] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0052] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0053] As described in the background technology of the present application, in the related art, the battery cells after hot pressing are scanned and inspected by offline CT scanning technology. Specifically, after the hot pressing of the battery cells is completed, the staff fixes a battery cell after hot pressing on a jig. During the inspection, the ray emitting source emits X-rays and irradiates one of the corners of the battery cell to scan and inspect one of the corners of the battery cell. Then, the battery cell is flipped so that the other corner of the battery cell is within the irradiation range of the X-rays to scan and inspect the other corner of the battery cell. The rays that have scanned the battery cell are received by the receiver and transmitted to the computer to obtain a three-dimensional model of the battery cell, so that the alignment of the positive and negative electrodes of the battery cell can be detected through the three-dimensional model. After the inspection of the battery cell is completed, the staff removes the inspected battery cell and then fixes the next battery cell to be inspected on the jig to scan and inspect the alignment of the positive and negative electrodes of the next battery cell to be inspected after hot pressing.

[0054] However, the above-mentioned method of testing the battery cells requires testing the battery cells one by one, which greatly slows down the testing efficiency of the battery cells and is not conducive to improving the production efficiency of lithium batteries.

[0055] Based on this, the utility model provides a detection device that can detect multiple battery cells at the same time, effectively improving the detection efficiency of the battery cells.

[0056] The technical solution of the present application will be described in detail below with reference to specific embodiments and drawings.

[0057] The present application embodiment provides a detection device, such as Figure 1 and Figure 2 As shown, it includes a turntable 1, a loading assembly 2, a unloading assembly 3 and a detection assembly 4. Among them, the turntable 1 has a detection loading station (such as Figure 1 As shown in the dotted line frame 11), the inspection station (such as Figure 1 The dashed line frame 12 shows the material inspection station (as shown in FIG. Figure 1 The loading assembly 2 is arranged near the detection loading station, and the loading assembly 2 has a battery cell loading station (such as Figure 1 As shown in the dotted line frame 2a), the spacer loading station (as shown in Figure 1 The dotted line frame 2b shows the stacking station (as shown in FIG. Figure 1As shown in the dotted frame 2c, the loading component 2 includes a first loading transport member 22 and a stacking conveyor belt 21. The first loading transport member 22 is used to transport the battery cell 20 located at the battery cell loading station to the stacking station, and to transport and stack the barrier members 6 located at the barrier member loading station onto the battery cell 20 located at the stacking station. The stacking conveyor belt 21 is arranged between the stacking station and the inspection loading station; the unloading component 3 is used to unload the stacked battery cells 20 and barrier members 6 that have been inspected from the inspection unloading station; the inspection component 4 is arranged on one side of the inspection station, and is used to inspect the stacked battery cells 20 and barrier members 6 located at the inspection station.

[0058] It should be noted that Figure 1 The straight arrows shown in the figure indicate the transmission direction of the battery cell 20 or the barrier member 6. Figure 1 The rotation arrow shown in illustrative figures indicates the rotation direction of the turntable 1 when the battery cell 20 is detected.

[0059] As mentioned above, the turntable 1 has an inspection loading station, an inspection station and an inspection unloading station, that is, the turntable 1 can rotate around its own rotation axis and pass through the inspection loading station, the inspection station and the inspection unloading station in sequence, so that when the battery cell 20 is placed on the inspection loading station, the turntable 1 can rotate to the inspection station and the inspection unloading station in sequence to inspect the battery cell 20.

[0060] The first loading and transporting member 22 is used to transport the battery cell 20 located at the battery cell loading station to the stacking station, and is used to transport and stack the barrier member 6 located at the barrier member loading station onto the battery cell 20 located at the stacking station, so that the battery cell 20 and the barrier member 6 can be stacked at the stacking station to form a stack. At this time, multiple battery cells 20 can be separated by the barrier member 6, that is, when multiple battery cells 20 are stacked, one barrier member 6 can be stacked between two adjacent battery cells 20; and the stacking conveyor 21 is arranged at the stacking station. Between the inspection and loading station, the stacked cells 20 and the barrier 6 located on the stacking station can be transferred from the stacking station to the inspection and loading station, and then the stacked cells 20 and the barrier 6 can be loaded onto the inspection and loading station, and can be inspected by the inspection component 4 as the turntable 1 rotates to the inspection station, and then the stacked cells 20 and the barrier 6 that have been inspected are unloaded by the unloading component 3 as the turntable 1 rotates to the inspection unloading station, so as to complete the inspection process of the stacked cells 20 and the barrier 6. Thus, the above-mentioned inspection equipment 10 can simultaneously inspect multiple cells 20 through the inspection component 4, effectively improving the inspection efficiency of the cells 20 and the production efficiency of the lithium battery, and the cells 20 and the barrier 6 can be respectively transported by the first loading and handling component for stacking, which can effectively improve the stacking efficiency of the cells 20 and the barrier 6 compared to manually stacking the cells 20 and the barrier 6, thereby further improving the inspection efficiency of the cells 20.

[0061] The battery cells 20 and the barrier members 6 are stacked at the stacking station. Two battery cells 20 can be stacked with one barrier member 6, that is, the barrier member 6 is located between the two battery cells 20; or three battery cells 20 can be stacked with two barrier members 6, and one barrier member 6 is placed between two adjacent battery cells 20; this is not limited here. Of course, the number of stacked battery cells 20 and barrier members 6 can also be other numbers. The above number of stacked battery cells 20 and barrier members 6 is only an example, and does not mean that only two or three battery cells 20 can be stacked through the barrier member 6.

[0062] In addition, the detection component 4 may include a CT scanner to perform a CT scan on the battery cell 20, for example, to detect the alignment of the positive and negative electrodes in the battery cell 20; or the detection component 4 may include an industrial camera to take pictures of the battery cell 20, for example, to detect whether the tabs in the battery cell 20 are folded, or to detect whether the weld marks on the tabs in the battery cell 20 are attached with tape. Of course, the detection component 4 may also include other detectors, which are not limited here.

[0063] Exemplarily, when the detection component 4 includes a CT scanner and the battery cell 20 is detected, the CT scanner may include a radiation emission source, a detector and a computer. The emission source may be located on one side of the battery cell 20 (such as the upper side) and may emit radiation, such as X-rays, to scan the battery cell 20 from top to bottom. The detector may be located on the other side of the battery cell 20 (such as the lower side), may receive the radiation emitted by the emission source, and may transmit the received radiation to the computer. The computer may establish a three-dimensional model of the battery cell 20 based on the signal transmitted by the detector to detect the alignment of the positive and negative electrodes of the battery cell 20.

[0064] The stacking conveyor belt 21 can be any one of a flat conveyor belt, a roller conveyor belt, a mesh conveyor belt, etc., and is not limited here.

[0065] It is understandable that the detection device 10 in the present application can detect the battery cell 20, and can also detect the tablet casing, mobile phone casing, etc., which is not limited here.

[0066] Optionally, the first loading and transporting member 22 is configured to transport the first battery cell 20 located at the battery cell loading station to the stacking station, then transport the barrier member 6 located at the barrier member loading station to the first battery cell 20 located at the stacking station, and finally transport the second battery cell 20 located at the battery cell loading station to the barrier member 6 located on the first battery cell 20.

[0067] Thus, two battery cells 20 and a barrier member 6 can be stacked at the stacking station, so that when the stacked battery cells 20 and the barrier member 6 are inspected by the inspection component 4 at the inspection station, the two battery cells 20 can be inspected at the same time, so as to improve the inspection efficiency of the battery cells 20 and also enable the inspection of the battery cells 20 to have a better effect.

[0068] Exemplarily, the first loading and transporting member 22 can transport the first lying battery cell 20 from the battery cell loading station to the stacking station, and then transport the barrier member 6 from the barrier member loading station to the stacking station and stack it on the first battery cell 20, and finally transport the second lying battery cell 20 from the battery cell loading station to the stacking station and stack it on the barrier member 6, forming a stack of two battery cells 20 with a barrier member 6 sandwiched between them.

[0069] Among them, when the partition 6 is located between two adjacent battery cells 20, the projection of the partition 6 on the surface of the battery cell 20 that is in contact with the partition 6 is located within the surface of the battery cell 20 that is in contact with the partition 6. Therefore, the influence of the partition 6 on the detection of the battery cell 20 can be reduced, thereby improving the detection effect of the stacked battery cells 20.

[0070] Optionally, the barrier member 6 can be at least one of a partition plate and a barrier bracket. Thus, by reasonably setting the size of the partition plate or the barrier bracket, the barrier member 6 can have a larger support range for the battery cell 20, so that the combination of the stacked battery cells 20 and the barrier member 6 can be more stable and firm, so that the multiple battery cells 20 are not prone to tilt or shake during detection, thereby improving the detection effect of the battery cells 20.

[0071] As mentioned above, when the stacked battery cells 20 and the barrier members 6 are transported from the stacking conveyor belt 21 to the inspection loading station, they can be transported manually or by a transport member, which is not limited here. The following is a detailed description of transporting the stacked battery cells 20 and the barrier members 6 from the stacking conveyor belt 21 to the inspection loading station by a transport member as an example.

[0072] Alternatively, if Figure 1 As shown, the loading assembly 2 also includes a loading conveyor belt 23 and a second loading transport member 24, wherein the loading conveyor belt 23 is used to transport the battery cells 20 to be inspected to the battery cell loading station; the second loading transport member 24 is movably arranged between the stacking conveyor belt 21 and the inspection loading station, and is used to transport the stacked battery cells 20 and the barrier members 6 located on the stacking conveyor belt 21 to the inspection loading station.

[0073] Therefore, compared with manually transporting the battery cells 20 to be inspected to the battery cell loading station, the efficiency of transporting the battery cells 20 to be inspected to the battery cell loading station can be effectively improved, thereby effectively improving the efficiency of transporting the battery cells 20 from the battery cell loading station to the stacking station, and further improving the inspection efficiency of the battery cells 20. Moreover, by arranging the second loading and transporting member 24 between the stacking conveyor belt 21 and the inspection and loading station, compared with manually transporting the stacked battery cells 20 and the barrier member 6 from the stacking conveyor belt 21 to the inspection and loading station, time and labor are saved, and the inspection efficiency of the battery cells 20 is further improved.

[0074] Among them, the implementation method of the loading conveyor belt 23 can be roughly the same as the implementation method of the stacking conveyor belt 21. The details can be referred to above and will not be repeated here.

[0075] The second loading and transporting member 24 may have a variety of implementation methods. In one possible implementation method, the second loading and transporting member 24 may include a gantry and a loading mechanical claw arranged on the gantry. The gantry is arranged between the stacking conveyor belt 21 and the detection loading station. The loading mechanical claw can be movably arranged on the gantry to move between the stacking conveyor belt 21 and the detection loading station to transport the stacked battery cells 20 and the barrier members 6 on the stacking conveyor belt 21 to the detection loading station.

[0076] In another possible implementation, the second loading and transporting member 24 includes a four-axis robot. Thus, the second loading and transporting member 24 can be easily implemented, reducing costs, and can flexibly rotate and transport the stacked battery cells 20 and the barrier members 6, so as to facilitate adjusting the stacked battery cells 20 and the barrier members 6 to a suitable posture and placing them on the inspection and loading station, thereby improving the inspection efficiency of the battery cells 20.

[0077] Of course, the second loading and transporting member 24 may also include a three-axis robot, a five-axis robot, etc., which is not limited here.

[0078] The above-mentioned first loading and conveying member 22 may include a conveying member to respectively convey the battery cell 20 located at the battery cell loading station and the barrier member 6 located at the barrier member loading station, thereby reducing the number of parts of the first loading and conveying member 22 and reducing the cost; alternatively, the first loading and conveying member 22 may include two conveying members, one of which is used to convey the battery cell 20 located at the battery cell loading station, and the other is used to convey the barrier member 6 located at the barrier member loading station.

[0079] Optionally, when the first loading transport member 22 includes two transport members, as Figure 1As shown, the first loading and conveying member 22 includes a first sub-loading and conveying member 221 and a second sub-loading and conveying member 222, wherein the first sub-loading and conveying member 221 is movably arranged between the battery cell loading station and the stacking station, and is used to convey the battery cell 20 located at the battery cell loading station to the stacking station; the second sub-loading and conveying member 222 is movably arranged between the barrier member loading station and the stacking station, and is used to convey the barrier member 6 located at the barrier member loading station to the stacking station, and stack it on the battery cell 20 located at the stacking station.

[0080] Therefore, the battery cells 20 and the barrier members 6 can be transported independently without interfering with each other, thereby effectively improving the stacking efficiency of the battery cells 20 and the barrier members 6 , thereby improving the detection efficiency of the battery cells 20 .

[0081] The first sub-loading and transporting member 221 may have a variety of implementations. In one possible implementation, the first sub-loading and transporting member 221 may include a robot, such as a three-axis robot, a four-axis robot, a five-axis robot, and the like.

[0082] In another possible implementation, the first sub-loading transport member 221 includes a guide rail and a robot. The guide rail is arranged between the loading conveyor belt 23 and the stacking conveyor belt 21. The robot is slidably connected to the guide rail, and the robot can also be lifted and lowered in the vertical direction.

[0083] Therefore, the structure of the first sub-loading and conveying member 221 can be relatively simple and easy to implement, and the battery cells 20 can be conveyed relatively flexibly.

[0084] Among them, the manipulator may include a rotating motor, a lifting hydraulic cylinder and a clamping claw, the shell of the lifting hydraulic cylinder can be slidably connected to the guide rail, the telescopic end of the lifting hydraulic cylinder can be connected to the rotating motor, and the rotating drive end of the rotating motor can be connected to the clamping claw to drive the clamping claw to rotate, and the clamping claw can clamp the battery cell 20; it can also be said that the manipulator includes a suction cup, and the suction cup is provided with an adsorption hole connected to the vacuum extraction equipment, and the suction cup can pick up the battery cell 20 by vacuum adsorption of the battery cell 20; of course, the manipulator may also have other implementation methods, such as, including an adhesive piece, the adhesive surface of the adhesive piece is coated with glue to adhere to the battery cell 20, which is not limited here.

[0085] In addition, the implementation method of the second sub-loading and transporting member 222 can be roughly the same as the implementation method of the first sub-loading and transporting member 221. For example, the second sub-loading and transporting member 222 includes a guide rail and a manipulator. The guide rail is set between the barrier member loading station and the stacking conveyor 21. The manipulator is slidably connected to the guide rail, and the manipulator can also be lifted and lowered in the vertical direction. In this way, the structure of the second sub-loading and transporting member 222 can be relatively simple and easy to implement, and the battery cells 20 can be transported more flexibly.

[0086] It should be noted that the implementation method of the second sub-loading and transporting member 222 may be different from the implementation method of the first sub-loading and transporting member 221, and can be specifically configured according to actual conditions, which is not limited here.

[0087] In some embodiments, Figure 1 As shown, the blanking assembly 3 has a splitting station (such as Figure 1 As shown in the dotted line frame 3a), the battery cell unloading station (as shown in Figure 1 The dashed line frame 3b shows the material cutting station of the partition member (as shown in FIG. Figure 1 The unloading assembly 3 includes a splitting conveyor belt 31 and a unloading transport member 32. The splitting conveyor belt 31 is arranged between the detection unloading station and the splitting station; the unloading transport member 32 is used to transport the stacked battery cells 20 and the barrier members 6 that have been inspected from the detection unloading station to the splitting conveyor belt 31, and to transport the battery cells 20 from the splitting station to the battery cell unloading station, and to transport the barrier members 6 from the splitting station to the barrier member unloading station.

[0088] Thus, the stacked battery cells 20 and the barrier 6 that have been inspected can be transported from the inspection unloading station to the splitting conveyor belt 31 through the unloading transport piece 32, and the stacked battery cells 20 and the barrier 6 that have been inspected can be transferred to the splitting station through the splitting conveyor belt 31, thereby effectively improving the unloading efficiency of the stacked battery cells 20 and the barrier 6 that have been inspected, so that the stacked battery cells 20 and the barrier 6 to be inspected can enter the inspection station for inspection, so that the inspection of the stacked battery cells 20 and the barrier 6 can have a more compact rhythm, further improving the inspection efficiency of the battery cells 20.

[0089] In addition, the unloading transport member 32 is also used to transport the battery cell 20 from the splitting station to the battery cell unloading station, and to transport the partition member 6 from the splitting station to the partition member unloading station, which effectively improves the splitting efficiency of the stacked battery cells 20 and the partition member 6, and is beneficial to improving the detection rhythm of the battery cells 20, thereby improving the detection efficiency of the battery cells 20.

[0090] Among them, the implementation method of the split conveyor belt 31 can be roughly the same as the implementation method of the stack conveyor belt 21. For details, please refer to the above and will not be repeated here.

[0091] There are many ways to implement the unloading and handling. In one possible implementation, the unloading and handling piece 32 may include a handling piece, which can be moved between the inspection unloading station and the splitting conveyor belt 31, between the splitting station and the battery cell unloading station, and between the splitting station and the partition unloading station, so as to respectively transport the stacked battery cells 20 and the partitions 6, and the battery cells 20 and the partitions 6 that have been inspected, thereby effectively reducing the number of parts of the unloading and handling piece 32 and reducing costs.

[0092] In another possible implementation, Figure 1 As shown, the material unloading and conveying member 32 includes a first material unloading and conveying member 321 and a second material unloading and conveying member 322, wherein the first material unloading and conveying member 321 is movably arranged between the detection unloading station and the splitting conveyor belt 31, and is used to transport the stacked battery cells 20 and the barrier members 6 that have completed the inspection from the detection unloading station to the splitting conveyor belt 31; the second material unloading and conveying member 322 is movably arranged between the splitting station, the battery cell unloading station and the barrier member unloading station, and is used to transport the battery cell 20 from the splitting station to the battery cell unloading station, and is used to transport the barrier member 6 from the splitting station to the barrier member unloading station.

[0093] In this way, the stacked battery cells 20 and the barrier members 6 that have completed inspection can be transported from the inspection unloading station to the splitting conveyor belt 31, and the battery cells 20 can be transported from the splitting station to the battery cell unloading station, and the barrier members 6 can be transported from the splitting station to the barrier member unloading station independently without interfering with each other. Moreover, the stacked battery cells 20 and the barrier members 6 can be transported simultaneously with the battery cells 20 and the barrier members 6, which effectively improves the unloading efficiency of the battery cells 20 and the barrier members 6, and is beneficial to improving the inspection efficiency of the battery cells 20.

[0094] The splitting station may be located at one end of the splitting conveyor belt 31 away from the detection and unloading station. Of course, the splitting station may also be located at one side of the splitting conveyor belt 31, which is not limited here.

[0095] In addition, the implementation method of the first unloading conveying member 321 can be substantially the same as the implementation method of the second loading conveying member 24 , and the details can be referred to above, which will not be described again here.

[0096] The implementation method of the second unloading conveying member 322 can be substantially the same as that of the first loading conveying member 22 , and the details can be referred to above, which will not be described again here.

[0097] Alternatively, if Figure 1 As shown, the blanking assembly 3 further includes a barrier member return conveyor belt 33, and the barrier member return conveyor belt 33 is arranged between the barrier member blanking station and the barrier member loading station.

[0098] In this way, the unloaded partition member 6 can be promptly returned to the partition member loading station to be stacked with the new battery cell 20 to be tested, so that the partition member 6 can be reused, saving costs. The partition member 6 can be transferred from the partition member unloading station to the partition member loading station through the partition member return conveyor belt 33. Compared with manual handling, the partition member 6 can be promptly returned, saving time and effort.

[0099] The implementation of the barrier member return conveyor belt 33 may be substantially the same as the implementation of the stacking conveyor belt 21 , and will not be described in detail herein.

[0100] In addition, if Figure 1 As shown, the unloading assembly 3 also includes a battery cell unloading and conveying assembly 34, which is used to transfer the battery cells 20 that have passed the inspection from the battery cell unloading station to the next station, and to transfer the battery cells 20 that have failed the inspection from the battery cell unloading station to the defective product storage area.

[0101] As a result, the battery cells 20 that have passed the inspection can be transferred to the next workstation in a relatively time-saving and labor-saving manner, or the battery cells 20 that have failed the inspection can be transferred to the failed storage area in a relatively time-saving and labor-saving manner, thereby improving efficiency.

[0102] Among them, the battery cell unloading and transmission component 34 can have multiple implementation methods. In one possible implementation method, the battery cell unloading and transmission component 34 may include a conveyor belt, which is arranged between the battery cell unloading station and the next station and passes through the defective product storage area. Thus, the battery cell 20 can be transmitted from the battery cell unloading station to the next station through the conveyor belt, and during the transmission process, if the battery cell 20 is an unqualified battery cell 20, it can be manually removed from the conveyor belt when passing through the defective product storage area.

[0103] In another possible implementation, Figure 1 As shown, the battery cell unloading conveyor assembly 34 includes a first battery cell unloading conveyor belt 341, a second battery cell unloading conveyor belt 342 and a third unloading conveyor 343, wherein the first battery cell unloading conveyor belt 341 is arranged between the battery cell unloading station and the next station; the second battery cell unloading conveyor belt 342 is arranged between the first battery cell unloading conveyor belt 341 and the defective product storage area; the third unloading conveyor 343 is movably arranged between the first battery cell unloading conveyor belt 341 and the second battery cell unloading conveyor belt 342, and is used to transport the unqualified battery cells 20 from the first battery cell unloading conveyor belt 341 to the second battery cell unloading conveyor belt 342.

[0104] Therefore, the qualified battery cells 20 are transferred to the next workstation via the first unloading conveyor belt, so that the transportation of the qualified battery cells 20 is not easily affected by the distance between the battery cell unloading workstation and the next workstation, and the unqualified battery cells 20 on the first unloading conveyor belt can be transferred to the second battery cell unloading conveyor belt 342 via the third unloading conveyor 343, thereby avoiding the unqualified battery cells 20 from being transferred to the next workstation.

[0105] Furthermore, by disposing the second battery cell unloading conveyor belt 342 between the first battery cell unloading conveyor belt 341 and the defective product storage area, the position of the defective product storage area can be less easily affected by the first battery cell unloading conveyor belt 341 .

[0106] Among them, the implementation method of the first battery cell unloading conveyor belt 341 and the second battery cell unloading conveyor belt 342 can be substantially the same as the implementation method of the stacking conveyor belt 21 , which will not be described in detail herein.

[0107] The implementation method of the third unloading conveying member 343 can be roughly the same as the implementation method of the first sub-loading conveying member 221, and can also be roughly the same as the implementation method of the second loading conveying member 24. No limitation is made here, and the specific implementation method can be referred to above, and will not be repeated here.

[0108] Optionally, the detection equipment 10 may also include an identification component, which is arranged downstream of the battery cell unloading station and also upstream of the third unloading conveying member 343. The identification component is electrically connected to the third unloading conveying member 343. The identification component is used to scan and identify the battery cells 20 that pass the inspection and those that fail the inspection.

[0109] It needs to be explained that the above-mentioned identification component is arranged downstream of the battery cell unloading station and also upstream of the third unloading conveying member 343, which means that in the inspection process of the battery cell 20, the identification component is located downstream of the battery cell unloading station and upstream of the third unloading conveying member 343, and it does not mean that in terms of orientation, the identification component is located downstream of the battery cell unloading station and upstream of the third unloading conveying member 343.

[0110] In this way, the battery cells 20 that fail the inspection can be detected in time after being removed from the battery cell unloading station, so that the third unloading transport member 343 can be controlled in time to transport the battery cells 20 that fail the inspection to the defective product storage area, effectively preventing the battery cells 20 that fail the inspection from being transferred to the next station.

[0111] Among them, the identification component can be an industrial camera, a QR code scanner, a barcode scanner, etc., which is not limited here and can be selected according to actual conditions.

[0112] In addition, the detection equipment 10 may also include a control component, which can be electrically connected to the detection component 4, the identification component and the third unloading and conveying member 343 respectively, so that when the battery cell 20 detected by the detection component 4 is unqualified, the identification code of the unqualified battery cell 20 can be transmitted to the control component, the identification component scans and identifies the battery cell 20 transmitted from the battery cell unloading station, and transmits the scanned identification code of the battery cell 20 to the control component, the control component can compare the identification code transmitted from the identification component with the identification code of the unqualified battery cell 20 transmitted by the detection component 4, and once the identification codes are consistent, the third unloading and conveying member 343 can be controlled to convey the corresponding battery cell 20 to the second battery cell unloading conveyor belt 342.

[0113] Optionally, the detection device 10 may also include a code scanning component, which can be arranged upstream of the battery cell loading station, such as on one side of the loading conveyor belt 23, so as to scan and identify the battery cell 20 transmitted on the loading conveyor belt 23; and the code scanning and identification component can be electrically connected to the control component to transmit the identification code of the battery cell 20 scanned and identified to the control component.

[0114] It needs to be explained that the above-mentioned code scanning component is arranged upstream of the battery cell loading station means that in the detection process, the code scanning component is located upstream of the battery cell loading station, which does not mean that the code scanning component is located upstream of the battery cell loading station in terms of direction position.

[0115] In some embodiments, Figure 1-Figure 5 As shown, there are multiple inspection stations, and the inspection loading station, multiple inspection stations and the inspection unloading station are evenly spaced around the rotating axis of the turntable 1.

[0116] Thus, the inspection of the stacked battery cells 20 and the barrier members 6 can be subdivided into multiple steps for inspection, so that multiple stacked battery cells 20 and barrier members 6 can be subjected to different inspection steps at multiple inspection stations at the same time, further improving the inspection efficiency of the battery cells 20.

[0117] Moreover, the inspection loading station, multiple inspection stations and the inspection unloading station are evenly spaced around the rotating axis of the turntable 1, so that the angle of rotation of the turntable 1 from one station to the next adjacent station can be the same, so that the rotation rhythm of the turntable 1 can be more uniform, which facilitates the rhythm control of loading, inspection and unloading of the stacked battery cells 20 and the barrier members 6.

[0118] The number of the inspection stations may be two, three, four or more, which is not limited here.

[0119] Exemplarily, when the number of the inspection stations is two, the inspection stations may include a first inspection station (eg Figure 3 The dashed line frame 121 shows the second inspection station (shown in FIG. Figure 3 As shown in the dotted frame 122, the loading inspection station, the first inspection station, the second inspection station and the unloading inspection station are evenly spaced around the rotating axis of the turntable 1, so that the angle between two adjacent stations in the loading inspection station, the first inspection station, the second inspection station and the unloading inspection station is 90°, so that the stacked battery cells 20 and the barrier 6 can be rotated to the next station every time the turntable 1 rotates 90°, so that the rotation control of the stacked battery cells 20 and the barrier 6 driven by the turntable 1 is relatively simple and easy to implement, and the two stacked battery cells 20 and the barrier 6 can be subjected to different inspections at the first inspection station and the second inspection station respectively, thereby further improving the inspection efficiency of the battery cells 20.

[0120] When the number of the detection stations is four, the detection stations may include a first detection station, a second detection station, and a third detection station (such as Figure 4 The fourth inspection station (shown in the dashed box 123) and the fourth inspection station (shown in the dashed box 123) Figure 4 As shown in the dotted frame 124, the loading inspection station, the first inspection station, the second inspection station, the third inspection station, the fourth inspection station and the unloading inspection station are evenly spaced around the rotating axis of the turntable 1, so that the angle between any two adjacent loading inspection stations, the first inspection station, the second inspection station, the third inspection station, the fourth inspection station and the unloading inspection station is 60°, so that the stacked battery cells 20 and the barrier 6 can be rotated to the next station every time the turntable 1 rotates 60°, so that the four stacked battery cells 20 and the barrier 6 can be subjected to different inspections at the four inspection stations at the same time, thereby making the inspection efficiency of the battery cells 20 higher.

[0121] In addition, when there are multiple detection stations, there may also be multiple detection components 4, and the multiple detection components 4 are arranged in a one-to-one correspondence with the multiple detection stations.

[0122] Alternatively, if Figure 3 and Figure 4 As shown, a jig 5 is provided on the turntable 1 , and the jig 5 can move with the turntable 1 between the inspection loading station, the inspection station and the inspection unloading station, and the jig 5 is used to carry the stacked battery cells 20 and the barrier members 6 .

[0123] Therefore, the stacked battery cells 20 and the barrier members 6 can rotate more smoothly with the turntable 1 , so that the detection of the battery cells 20 can have a better effect.

[0124] Among them, the number of jigs 5 can be one or more, and when the number of jigs 5 is more than one, the multiple jigs 5 can be respectively set corresponding to the inspection loading station, the inspection station and the inspection unloading station, so that after the stacked battery cells 20 and the partition members 6 are fixed on one of the jigs 5, as the turntable 1 rotates, the next jig 5 can be rotated to the inspection loading station to fix another stacked battery cell 20 and the partition member 6, thereby effectively improving the inspection efficiency of the battery cells 20.

[0125] In addition, if Figure 6 and Figure 7As shown, the jig 5 may include a supporting plate 51 and a clamping member 52. The clamping member 52 may be movably disposed on the supporting plate 51 in a direction approaching or moving away from the supporting plate 51, so as to clamp the stacked battery cells 20 and the barrier 6 between the clamping member 52 and the supporting plate 51, and to fix the stacked battery cells 20 and the barrier 6 more firmly on the supporting plate 51, so as to prevent the stacked battery cells 20 and the barrier 6 from sliding off the jig 5 during the inspection process; or to loosen the stacked battery cells 20 and the barrier 6 between the clamping member 52 and the supporting plate 51, so as to facilitate the removal of the stacked battery cells 20 and the barrier 6.

[0126] The pressing member 52 may be any one of a pressing block, a pressing roller, a pressing plate, etc., which is not limited here.

[0127] In addition, the jig 5 may also include a reset elastic member 53, one end of the reset elastic member 53 is connected to the clamping member 52, and the other end is connected to the supporting plate 51. The reset elastic member 53 is used to provide a force for the clamping member 52 to rotate toward the supporting plate 51, so that the stacked battery cells 20 and the barrier members 6 can be firmly fixed on the jig 5.

[0128] The jig 5 may also include a clamping drive and a pressure block. The driving end of the clamping drive is connected to the pressure block, and is used to drive the pressure block to move toward or away from the clamping member 52. When the pressure block squeezes the clamping member 52 in a direction close to the clamping member 52, the clamping member 52 can move in a direction away from the supporting plate 51 to loosen the stacked battery cells 20 and the partition member 6 between the clamping member 52 and the supporting plate 51. The operation of removing the stacked battery cells 20 and the partition member 6 from the jig 5 is simple and convenient.

[0129] Optionally, the rotatable part of the jig 5 can be rotatably disposed on the turntable 1, so that the stacked battery cells 20 and the partition members 6 fixed on the jig 5 can also rotate relative to the turntable 1 as the jig 5 rotates, so that the stacked battery cells 20 and the partition members 6 can be rotated to different angles, thereby facilitating the detection of different positions of the stacked battery cells 20 and the partition members 6, and improving the detection effect of the detection equipment 10.

[0130] Exemplarily, when the alignment of the positive and negative electrodes of the hot-pressed battery cell 20 is detected, and the detection station includes the first detection station and the second detection station, first, the stacked battery cells 20 and the barrier 6 are loaded onto the jig 5 on the detection loading station. Then, the turntable 1 rotates 90° (such as 90° clockwise), and the jig 5 and the stacked battery cells 20 and the barrier 6 on the jig 5 are rotated to the first detection station and are within the detection angle of the detection component 4. At this time, the detection component 4 can be a CT scanner, and the CT scanner can scan the first corner of the stacked battery cells 20 and the barrier 6. For example, when the battery cell 20 is a square battery cell 20, the CT scanner can scan from the upper side of the stacked battery cells 20 and the barrier 6 downward, and at the same time, the stacked battery cells 20 and the barrier 6 rotate with the jig 5 relative to the turntable 1 until the first corner of the stacked battery cells 20 and the barrier 6 is scanned. Then, the turntable 1 continues to rotate 90°, and the jig 5 and the stacked battery cells 20 and the spacer 6 on the jig 5 are rotated to the second inspection station. At this time, the jig 5 can drive the stacked battery cells 20 and the spacer 6 to rotate until the second corner of the stacked battery cells 20 and the spacer 6 is within the inspection angle of the inspection component 4. Of course, the jig 5 can also drive the stacked battery cells 20 and the spacer 6 to rotate during the process of the turntable 1 rotating from the first inspection station to the second inspection station, which is not limited here. Then, the inspection component 4 can scan the second corner of the stacked battery cells 20 and the spacer 6, and at the same time, the jig 5 drives the stacked battery cells 20 and the spacer 6 to rotate until the inspection component 4 completes the scanning of the second corner, so as to obtain a three-dimensional model of the battery cell 20 on the computer and detect and judge the alignment of the positive and negative electrodes of the battery cell 20. Then, the turntable 1 continues to rotate 90°, and the jig 5 and the stacked battery cells 20 and the barrier 6 on the jig 5 are rotated from the second inspection station to the inspection unloading station. At this time, the stacked battery cells 20 and the barrier 6 that have been inspected can be unloaded from the inspection unloading station through the unloading assembly 3. Finally, the turntable 1 continues to rotate 90°, and the empty jig 5 is rotated from the inspection unloading station to the inspection loading station, so as to load the new stacked battery cells 20 and the barrier 6 to be inspected onto the jig 5. This reciprocating process can be repeated as the turntable 1 rotates, and the stacked battery cells 20 and the barrier 6 can be continuously loaded, inspected, and unloaded, which effectively improves the inspection efficiency of the inspection device 10.

[0131] It should be noted that the first corner and the second corner of the stacked battery cells 20 and the barrier member 6 may be two opposite corners along a diagonal line.

[0132] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
