[0001] The present invention relates to the technical field of detection devices, and particularly to a battery cell detection system and a detection method thereof.

Background Art

[0002] A battery cell is an important component of a battery. Before the battery cell is incorporated into the battery, it is necessary to detect the battery cell, particularly the degree of displacement of the electrode tabs of the battery cell.

[0003] In related technologies, the battery cell is placed on a turntable, and an optical machine and a detector are arranged on both sides of the turntable. The turntable completes the scanning by rotating the battery cell. In the detection process, since the battery cell is always in a rotating state, the battery cell is easily damaged. Also, to detect a plurality of battery cells, the optical machine needs to stop the beam multiple times for the loading and unloading operations on the plurality of battery cells, resulting in low detection efficiency. Alternatively, the battery cell is placed on a conveyor belt, and a rotatable optical machine and a detector are arranged on both sides of the conveyor belt. The battery cell is scanned while moving with the conveyor belt. Since the placement position of the battery cell is relatively fixed, to complete the detection of the four ends, the battery cell needs to be moved multiple times with the conveyor belt, resulting in low detection efficiency.

Those skilled in the art will be able to understand the specific meaning of these terms in this invention on a case-by-case basis.

[0025] The battery cell detection system according to an embodiment of the present invention will be described below with reference to Figures 1 to 4.

[0026] As shown in Figure 1, the battery cell detection system according to an embodiment of the present invention comprises a transport device 1, a first transfer device 2, and a detection device 3. The transport device 1 is used to transport the battery cell 100 to a gripping station. The first transfer device 2 is positioned opposite the transport device 1 in the vertical direction and comprises a first gripping mechanism 21 and a first moving mechanism 22 connected to each other. The first gripping mechanism 21 is used to grip the battery cell 100, and the first moving mechanism 22 is used to move the battery cell 100 from the gripping station to the detection station, and the first moving mechanism 22 is suitable for moving the part of the battery cell 100 to be detected to a predetermined position. The detection device 3 is positioned at the detection station and is used to detect the part of the battery cell 100 to be detected.

[0027] As an example, the battery cell detection system according to an embodiment of the present invention is used to detect the four ends of a rectangular battery cell 100. Since the four ends of the battery cell 100 are the parts to be detected, the battery cell 100 has four parts to be detected. Depending on the detection needs, one or more parts of the battery cell 100 are detected. The battery cell detection system is mainly used to detect the alignment of the polarity of the battery cell 100.

[0028] The battery cell detection system comprises a transport device 1, a first transfer device 2, and a detection device 3. The transport device 1 and the first transfer device 2 are arranged sequentially along the vertical direction. The detection device 3 is located at the detection station and comprises a radiating means 31 and a detector means 32. The radiating means 31 and the detector means 32 are mounted on a rotating frame 33. The rotation of the rotating frame 33 drives the radiating means 31 and the detector means 32 to rotate around the central axis of the rotating frame 33. X-rays emitted from the radiating means 31 pass through the part of the battery cell 100 to be detected. The detector means 32 receives the X-rays that have passed through the part of the battery cell 100 to be detected and converts them into an electrical signal. The electrical signal is processed to generate a scanning image. Based on the scanning image, it is determined whether or not there is a defect in the part of the battery cell 100 to be detected, and the detection of the part to be detected is completed.

[0029] The conveying device 1 may be a belt conveying device, and the conveying device 1 comprises a driving roller, a driven roller, and a conveyor belt, with the conveyor belt being sleeve-mounted on the driving roller and the driven roller. The gripping station is positioned in the direction of transport of the conveyor belt, the battery cell 100 is placed on the conveyor belt, and the battery cell 100 moves to the gripping station along the conveyor belt.

[0030] The battery cells 100 from the previous process may be transferred to the conveyor belt of the conveyor device 1 by transfer equipment, or the battery cells 100 from the previous process may be transferred to the conveyor belt of the conveyor device 1 by an operator.

[0031] The first transfer device 2 comprises a first gripping mechanism 21 and a first moving mechanism 22 connected to each other. The first gripping mechanism 21 faces the conveying surface of the conveyor belt and grips the battery cell 100. The first moving mechanism 22 is capable of linear and rotational motion, and the first moving mechanism 22 drives the first gripping mechanism 21 to reciprocate between the gripping station and the detection station.

[0032] The first moving mechanism 22 drives the first gripping mechanism 21 to move to the gripping station, where the first gripping mechanism 21 grips the battery cell 100 on the conveyor belt. After the first gripping mechanism 21 grips the battery cell 100, the battery cell 100 is separated from the conveying surface of the conveyor belt, and the first moving mechanism 22 drives the battery cell 100 to move to the detection station. At the detection station, the first moving mechanism 22 drives the battery cell 100 to rise vertically to a preset height. At the predetermined height, the battery cell 100 is located on the detection reference plane of the detection device 3, the distance between the detection reference plane and the transmitting end of the radiating means 31 satisfies the first distance requirement, and the distance between the detection reference plane and the receiving end of the detector means 32 satisfies the second distance requirement.

[0033] The battery cell 100 moves to a preset height, and the first moving mechanism 22 drives the battery cell 100 to rotate by a preset angle so that the part of the battery cell 100 to be detected enters the beam area of ​​the detection reference plane. At this time, the part of the battery cell 100 to be detected is in a predetermined position, and this predetermined position information includes the height information and angle information of the battery cell 100. With the part of the battery cell 100 to be detected in a predetermined position, the radiating means 31 and the detector means 32 rotate around the central axis to detect the part to be detected.

[0034] As shown in Figure 4, the battery cell 100 has four parts to detect, defined as the first part to detect 101, the second part to detect 102, the third part to detect 103, and the fourth part to detect 104. The first part to detect 101 and the third part to detect 103 are located on the first diagonal of the battery cell 100, while the second part to detect 102 and the fourth part to detect 104 are located on the second diagonal of the battery cell 100. Below, two detection processes are described according to the detection needs.

[0035] When it is necessary to detect a first part 101 and a second part 102 of the battery cell 100, the first moving mechanism 22 rotates so that the first part 101 of the battery cell 100 rotates within the beam region, scans the first part 101 to generate a first scan image, and determines whether or not there is a defect in the first part 101 based on the first scan image. After the detection of the first part 101 is completed, the first moving mechanism 22 rotates to rotate the second part 102 of the battery cell 100 into the beam region, scans the second part 102 to generate a second scan image, and determines whether or not there is a defect in the second part 102 based on the second scan image. In this way, the detection of the first part 101 and the second part 102 is completed.

[0036] If it is necessary to detect all four parts of the battery cell 100 that need to be detected, the first moving mechanism 22 is rotated to sequentially move the first part to be detected 101, the second part to be detected 102, the third part to be detected 103, and the fourth part to be detected 104 of the battery cell 100 into the beam region, and it is determined whether or not there are defects in the four parts of the battery cell 100 based on the first scan image, second scan image, third scan image, and fourth scan image generated by the scan.

[0037] During the detection process, the battery cell 100 is in a horizontal position, and the radiating means 31 and the detector means 32 rotate around the central axis. Since the battery cell 100 does not need to rotate, motion damage to the battery cell 100 caused by rotation during the detection process can be effectively avoided.

[0038] In conventional technology, battery cells move along a conveyor belt to a detection station, and the battery cells are positioned on the conveyor belt. Once detection of one part of the battery cell is complete, the battery cell moves along the conveyor belt to the rear end, and then positions itself at the front end of the conveyor belt to adjust its position. The battery cell then moves along the conveyor belt again to the detection station to detect the next part to be detected. To detect multiple parts of a battery cell, the battery cell must move along the conveyor belt multiple times, and its position must be adjusted multiple times, resulting in low detection efficiency.

[0039] In the battery cell detection system of the present invention, the battery cell 100 is separated from the conveyor belt at the detection station. Once detection of one part of the battery cell 100 is complete, there is no need to move the battery cell 100 again from the end of the conveyor belt to the detection station. To detect the next part to be detected, it is only necessary to rotate the next part to be detected of the battery cell 100 to a predetermined position at the detection station, thus effectively improving detection efficiency. Furthermore, the parts of the battery cell 100 that need to be detected can be rotated to a predetermined position according to the detection needs, which is advantageous for detection flexibility.

[0040] It can be understood that the transport device 1 detects the battery cell 100 gripped by the first gripping mechanism 21, and at the same time transports the next battery cell 100 to be detected to the gripping station, and that the transport device 1 also has a function to cache the next battery cell 100 to be detected.

[0041] After the detection of the battery cell 100 is complete, the first moving mechanism 22 descends vertically, and the first gripping mechanism 21 descends to the conveying surface near the conveyor belt. The first gripping mechanism 21 releases the battery cell 100, and the battery cell 100 is placed on the conveyor belt. Subsequently, the battery cell 100 moves along the conveyor belt to the loading / unloading station.

[0042] After the first gripping mechanism 21 releases the battery cell 100, the first transfer device 2 moves from the detection station to the gripping station and detects the next battery cell 100.

[0043] When detecting multiple battery cells 100, the radiating means 31 and the detector means 32 are always in a rotating state, eliminating the need to start and stop the radiating means 31 multiple times, which is advantageous for the stability of the operation of the detection device 3.

[0044] The transport device 1 transports the battery cells 100 to be detected to the gripping station, and the detected battery cells 100 to the loading / unloading station, and also has a function to cache the battery cells 100 to be detected. The first gripping mechanism 21 grips the battery cell 100, and the first moving mechanism 22 moves the battery cell 100 from the gripping station to the detection station by linear motion and rotational motion, rotating the part of the battery cell 100 to be detected within the beam area of ​​the detection device 3, thereby enabling detection of any part to be detected via the detection device 3.

[0045] The first gripping mechanism 21 grips the battery cell 100. After the battery cell 100 is separated from the transport surface of the transport device 1, the first moving mechanism 22 adjusts the position and orientation of the battery cell 100, enabling detection of any part of the battery cell 100 to be detected. This is advantageous for improving detection flexibility and detection efficiency.

[0046] In this embodiment of the present invention, the transport device 1 is used to transport and store the battery cells 100 to be detected. The first transport device 2 moves the battery cells 100 from the gripping station to the detection station. At the detection station, according to the detection needs, the first moving mechanism 22 moves any part of the battery cell 100 to be detected to a predetermined position and detects one or more parts of the battery cell 100. This improves the flexibility of detection and improves detection efficiency.

[0047] As shown in Figures 2 and 3, in an optional embodiment, the first moving mechanism 22 includes a first linear motion mechanism 221, a first lifting mechanism 222, and a first rotating mechanism 223. The first linear motion mechanism 221 is configured to move along a first direction and is used to move the battery cell 100 from a gripping station to a detection station. The first lifting mechanism 222 is configured to move along a vertical direction and is used to move the battery cell 100 to the detection reference plane of the detection device 3. The first rotating mechanism 223 is connected to either the first linear motion mechanism 221 or the first lifting mechanism 222 and is also connected to the first gripping mechanism 21 and is used to drive and rotate the battery cell 100 so that the part of the battery cell 100 to be detected is rotated to a predetermined position.

[0048] Specifically, the first linear motion mechanism 221 moves in a first direction parallel to the conveying direction of the conveying device 1, the first lifting mechanism 222 moves in a vertical direction, and the direction of the rotation axis of the first rotation mechanism 223 is parallel to the vertical direction. The first direction is shown as direction D1 in Figure 2, and the vertical direction is shown as direction D3 in Figures 2 and 3. The direction of the arc arrow in Figure 2 is the direction of rotation.

[0049] The first transfer device 2 comprises a mounting frame including a vertical beam and a horizontal support beam. One end of the vertical beam is fixed to a workbench or the ground, and the other end is connected to the horizontal support beam. The first linear motion mechanism 221 is mounted on the horizontal support beam.

[0050] The first linear motion mechanism 221 can be a gear rack drive mechanism, a screw nut drive mechanism, a synchronous belt drive mechanism, a slide rail and slider motion mechanism, etc. Optionally, the first linear motion mechanism 221 includes a first slide rail 2211, a first slider 2212 and a first mounting plate 2213, the first slider 2212 being slidably connected to the first slide rail 2211.

[0051] The first slide rail 2211 is installed on the underside of the horizontal support beam. Optionally, two first slide rails 2211 are provided, spaced apart along the width direction of the horizontal support beam. The first sliders 2212 are mounted on the upper surface of the first mounting plate 2213, and one, two, or more first sliders 2212 are mounted on each first slide rail 2211. The first linear motion mechanism 221 also includes a first horizontal drive component for moving the first sliders 2212 along the first slide rails 2211.

[0052] The first lifting mechanism 222 comprises a lifting drive component and a lifting section 2221. The fixed end of the lifting drive component is connected to the first mounting plate 2213, the drive end of the lifting drive component is connected to one end of the lifting section 2221, and the other end of the lifting section 2221 is connected to the first rotating mechanism 223. The lifting drive component is used to drive the lifting section 2221 to move it up and down vertically.

[0053] The first rotating mechanism 223 comprises a rotary drive component, a rotating part 2231, and a connecting part. The rotating part 2231 is rotatably connected to the lifting part 2221. A connecting part is provided on the bottom surface of the rotating part 2231, and the rotating part 2231 is connected to the first gripping mechanism 21 via the connecting part. The rotary drive component drives the rotating part 2231 to rotate.

[0054] The first gripping mechanism 21 has two clamping parts that can move closer to or further apart from each other, and the battery cell 100 is held between these two clamping parts.

[0055] The following describes in detail the operating procedures of each component of the first transfer device 2. The battery cell 100 to be detected is transported to the gripping station, the first transfer device 2 moves to the gripping station, and the lifting drive component drives the lifting section 2221 to lower the first gripping mechanism 21 vertically until it approaches the battery cell 100 at the gripping station. After the two gripping sections of the first gripping mechanism 21 grip the battery cell 100, the first horizontal drive component drives the first slider 2212 to move along the first slide rail 2211, moving the battery cell 100 to the detection station. The lifting drive component drives the lifting section 2221 to raise the battery cell 100 vertically until it moves vertically to the detection reference plane. Then, the rotation drive component drives the rotating section 2231 to rotate, rotating the part of the battery cell 100 to be detected into the beam area, and the detection device 3 detects the part to be detected.

[0056] When it is necessary to detect all four parts of the battery cell 100, the rotating unit 2231 drives the first part to be detected 101, the second part to be detected 102, the third part to be detected 103, and the fourth part to be detected 104 of the battery cell 100 to rotate sequentially within the beam region, thereby completing the detection of all four parts to be detected.

[0057] After the detection of battery cell 100 is complete, the first horizontal drive component drives the first slider 2212 to move along the first slide rail 2211, and the first transfer device 2 moves from the detection station to the gripping station along the first direction to detect the next battery cell 100.

[0058] The first horizontal drive component moves the first slider 2212 along the first slide rail 2211, moving the battery cell 100 from the gripping station to the detection station. The lifting drive component drives the lifting section 2221 to move vertically, causing the first gripping mechanism 21 to grip the battery cell 100 and move the battery cell 100 to the detection reference plane. The rotation drive component rotates the rotating section 2231, rotating any portion of the battery cell 100 to be detected within the beam area. The first linear motion mechanism 221, the first lifting mechanism 222, the first rotation mechanism 223, and the first gripping mechanism 21 work together to ensure an orderly connection of gripping, lifting, horizontal movement, and rotation, which is advantageous for the intelligent operation of the battery cell detection system.

[0059] As shown in Figure 2, in an optional embodiment, the first moving mechanism 22 further includes a second linear motion mechanism 224 connected to the first linear motion mechanism 221 and the first lifting mechanism 222. The second linear motion mechanism 224 is configured to move along a second direction and is driven to move the first lifting mechanism 222 and the first rotating mechanism 223 along the second direction such that the axis of rotation of the first rotating mechanism 223 is located on the central plane of the detection device 3. The second direction intersects the first direction.

[0060] Specifically, the second linear motion mechanism 224 can move along a second direction that is parallel to the horizontal direction and perpendicular to the first direction. This second direction is shown as the D2 direction in Figure 3.

[0061] The second linear motion mechanism 224 comprises a second slide rail 2242, a second slider 2241, and a second mounting plate 2243. The second slider 2241 is mounted on the underside of the first mounting plate 2213. Two groups of second sliders are spaced apart on the underside of the first mounting plate 2213. Each group of second sliders includes two spaced-apart second sliders 2241. Two second slide rails 2242 are mounted on the upper surface of the second mounting plate 2243. The two second slide rails 2242 are arranged in a one-to-one ratio with the two groups of second sliders. The second slider 2241 is slidably connected to the second slide rails 2242. The first lifting mechanism 222 can be mounted on the second mounting plate 2243.

[0062] The second slide rail 2242 slides relative to the second slider 2241, driving the first lifting mechanism 222 and the first rotating mechanism 223 to move along the second direction, so that the rotation axis of the first rotating mechanism 223 is positioned on the central plane of the detection device 3, and the position of the battery cell 100 is further fine-tuned so that the central plane of the battery cell 100 coincides with the central plane of the detection device 3, thereby preventing the battery cell 100 from shifting left or right along the second direction, and ensuring that the part to be detected is perfectly positioned within the beam region.

[0063] The sliding engagement position between the second slide rail 2242 and the second slider 2241 may be adjusted manually or by a second horizontal drive component.

[0064] The second linear motion mechanism 224 drives the first lifting mechanism 222, the first rotation mechanism 223, and the first gripping mechanism 21 to move along the second direction, ensuring that the central plane of the battery cell 100 coincides with the central plane of the detection device 3. As a result, after the first rotation mechanism 223 rotates to the target angle, the part of the battery cell 100 to be detected is precisely positioned within the beam region, ensuring detection accuracy.

[0065] In an optional embodiment, the first rotating mechanism 223 is suitable for driving the first gripping mechanism 21 to rotate to a target angle and rotating any part of the battery cell 100 to be detected to a predetermined position.

[0066] Specifically, the first rotating mechanism 223 can rotate 360 ​​degrees around its axis of rotation, allowing any part of the battery cell 100 to be detected to rotate to a predetermined position.

[0067] The battery cell 100 has a first end and a second end facing each other along the length of the battery cell 100, with the first part to be detected 101 and the second part to be detected 102 located at the first end, and the third part to be detected 103 and the fourth part to be detected 104 located at the second end.

[0068] The first rotating mechanism 223 rotates by a first angle to rotate the first part to be detected 101 to a predetermined position and complete the detection. Next, the first rotating mechanism 223 rotates by a second angle to rotate the second part to be detected 102 to a predetermined position and complete the detection. The first rotating mechanism 223 rotates by a third angle to rotate the third part to be detected 103 to a predetermined position and complete the detection. The first rotating mechanism 223 rotates by a fourth angle to rotate the fourth part to be detected 104 to a predetermined position and complete the detection.

[0069] In the detection station, the rotation of the first rotating mechanism 223 allows for the sequential detection of the four parts of the battery cell 100 to be detected, contributing to improved detection efficiency and quality.

[0070] As shown in Figure 1, in a selective embodiment, the battery cell detection system also includes a tray 200, which is used to hold the battery cells 100. The transport device 1 is used to transport the tray 200, which is loaded with the battery cells 100, to the gripping station.

[0071] Specifically, the battery cell detection system also includes a tray 200 for mounting the battery cells 100. The structure of the tray 200 is not particularly limited. The tray 200, which mounts the battery cells 100, moves together with the conveyor belt. The tray 200 reduces friction between the conveyor belt and the battery cells 100, protecting the battery cells 100.

[0072] The two gripping parts of the first gripping mechanism 21 grip the tray 200 and transport the battery cells 100 from the gripping station to the detection station. Since the first gripping mechanism 21 is in direct contact with the tray 200, it does not directly grip and damage the battery cells 100, thus protecting the battery cells 100.

[0073] Since the tray 200 is used to mount the battery cells 100, the battery cells 100 do not come into direct contact with the conveyor belt or the first gripping mechanism 21, thus effectively protecting the battery cells 100.

[0074] Selectively, the tray 200 can accommodate multiple battery cells 100, which are stacked vertically. The detection station can detect the parts of the multiple battery cells 100 to be detected in a single scan, further improving detection efficiency.

[0075] As shown in Figure 1, in a selective embodiment, the battery cell detection system further comprises a second transfer device 4, with the first transfer device 2 and the second transfer device 4 positioned on opposite sides of the detection device 3. The structure of the second transfer device 4 is the same as that of the first transfer device 2, and the second transfer device 4 comprises a second gripping mechanism 41 and a second moving mechanism 42 connected to each other. The first transfer device 2 is used to transport one battery cell 100 on one side of the detection device 3 to the detection station, and the second transfer device 4 is used to transport the other battery cell 100 on the other side of the detection device 3 to the detection station. The detection device 3 is used to synchronously detect the battery cell 100 gripped by the first transfer device 2 and the battery cell 100 gripped by the second transfer device 4.

[0076] Specifically, the second transfer device 4 and the first transfer device 2 have the same structure, and the first transfer device 2 and the second transfer device 4 are arranged symmetrically with respect to the detection device 3. That is, the first transfer device 2 and the second transfer device 4 are positioned on the first and second sides of the detection device 3, respectively, along the transport direction of the transport device 1.

[0077] The first transfer device 2 comprises a first gripping mechanism 21 and a first moving mechanism 22. The first moving mechanism 22 comprises a first linear motion mechanism 221, a first lifting mechanism 222, a first rotation mechanism 223, and a second linear motion mechanism 224. The second transfer device 4 comprises a second gripping mechanism 41 and a second moving mechanism 42. The second moving mechanism 42 comprises a first linear motion mechanism 221', a second linear motion mechanism 224', a second lifting mechanism 421, and a second rotation mechanism 422. The first linear motion mechanism 221' has the same structure as the first linear motion mechanism 221, the second linear motion mechanism 224' has the same structure as the second linear motion mechanism 224, the second lifting mechanism 421 has the same structure as the first lifting mechanism 222, and the second rotation mechanism 422 has the same structure as the first rotation mechanism 223.

[0078] The first transfer device 2 grasps one battery cell 100 and transports it to the detection station, and the second transfer device 4 grasps one battery cell 100 and transports it to the detection station. The detection device 3 can synchronously detect the battery cell 100 grasped by the first transfer device 2 and the battery cell 100 grasped by the second transfer device 4.

[0079] The conveying device 1 has a first gripping station and a second gripping station in the conveying direction. The conveying device 1 conveys two adjacent battery cells 100 to the first gripping station and the second gripping station, respectively. For the sake of explanation, the two battery cells 100 are defined as the first battery cell and the second battery cell, respectively. Due to the coordinated relationship between the two transfer devices, the conveying device 1, and the detection device 3, the battery cell detection system has multiple detection modes.

[0080] The detection process for the first detection mode will be described in detail below. The transport device 1 transports the first battery cell to the first gripping station, the first transfer device 2 moves to the first gripping station, the first gripping mechanism 21 grips the first battery cell, the first linear motion mechanism 221 moves the first battery cell to the detection station by horizontal linear motion, the first lifting mechanism 222 moves the first battery cell to the detection reference plane by lifting motion, the first rotation mechanism 223 rotates the first part to be detected 101 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the first part to be detected 101. Next, the first rotation mechanism 223 rotates the second part to be detected 102 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the second part to be detected.

[0081] After the detection of the first detection unit 101 and the second detection unit 102 is completed, the first lifting mechanism 222 drives the first battery cell down to a point close to the conveying surface of the conveyor belt, the first gripping mechanism 21 places the first battery cell on the conveyor belt, and the first battery cell moves to the second gripping station together with the conveyor belt.

[0082] The second transfer device 4 moves to the second gripping station, the second gripping mechanism 41 grips the first battery cell, the first linear motion mechanism 221' of the second transfer mechanism 42 moves the first battery cell to the detection station by horizontal linear motion, the second lifting mechanism 421 moves the first battery cell to the detection reference plane by lifting motion, the second rotating mechanism 422 rotates the third part to be detected 103 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the third part to be detected 103. Next, the second rotating mechanism 422 rotates the fourth part to be detected 104 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the fourth part to be detected 104.

[0083] It can be understood that when the first battery cell moves to the second gripping station, the second battery cell moves to the first gripping station together with the conveyor belt, and at the same time that the second gripping mechanism 41 grips the first battery cell located at the second gripping station, the first gripping mechanism 21 grips the second battery cell located at the first gripping station.

[0084] As the second moving mechanism 42 moves the first battery cell from the second gripping station to the detection station, the first moving mechanism 42 moves the second battery cell from the first gripping station to the detection station. The second rotating mechanism 422 rotates the third part to be detected 103 of the first battery cell into the beam region by rotational motion, and at the same time, the first rotating mechanism 223 rotates the first part to be detected 101 of the second battery cell into the beam region by rotational motion, and the detection device 3 synchronously detects the third part to be detected 103 of the first battery cell and the first part to be detected 101 of the second battery cell. For the same reason, the detection device 3 synchronously detects the fourth part to be detected 104 of the first battery cell and the second part to be detected 102 of the second battery cell.

[0085] The first transfer device 2 sequentially moves the first part to be detected 101 and the second part to be detected 102 of the battery cell 100 into the beam region and completes the detection of the first part to be detected 101 and the second part to be detected 102. The second transfer device 4 sequentially moves the third part to be detected 103 and the fourth part to be detected 104 of the battery cell 100 into the beam region and completes the detection of the third part to be detected 103 and the fourth part to be detected 104.

[0086] The first transfer device 2 moves one part of one battery cell 100 to be detected into the beam region, and simultaneously the second transfer device 4 moves one part of the other battery cell 100 to be detected into the beam region. Since the detection device 3 detects both parts of the two battery cells 100 simultaneously, it is advantageous for improving detection efficiency.

[0087] The detection process for the second detection mode is described in detail below. The transport device 1 transports the first battery cell to the first gripping station and the second battery cell to the second gripping station.

[0088] The first transfer device 2 moves to the first gripping station, and simultaneously the second transfer device 4 moves to the second gripping station. The first gripping mechanism 21 grips the first battery cell at the first gripping station, and the first moving mechanism 22 moves the first battery cell to the detection station. At the same time, the second gripping mechanism 41 grips the second battery cell at the second gripping station, and the second moving mechanism 42 moves the second battery cell to the detection station.

[0089] The first rotating mechanism 223 rotates the first part to be detected 101 of the first battery cell into the beam region, and the second rotating mechanism 422 rotates the fourth part to be detected 104 of the second battery cell into the beam region. The detection device 3 synchronously detects the first part to be detected 101 of the first battery cell and the fourth part to be detected 104 of the second battery cell.

[0090] Subsequently, the first rotating mechanism 223 rotates the second part to be detected 102 of the first battery cell into the beam region, and at the same time, the second rotating mechanism 422 rotates the third part to be detected 103 of the second battery cell into the beam region, and the detection device 3 synchronously detects the second part to be detected 102 and the third part to be detected 103 of the second battery cell.

[0091] Subsequently, the first rotating mechanism 223 rotates the third part to be detected 103 of the first battery cell into the beam region, and at the same time, the second rotating mechanism 422 rotates the second part to be detected 102 of the second battery cell into the beam region, and the detection device 3 synchronously detects the third part to be detected 103 of the first battery cell and the second part to be detected 102 of the second battery cell.

[0092] Subsequently, the first rotating mechanism 223 rotates the fourth part to be detected 104 of the first battery cell into the beam region, and at the same time, the second rotating mechanism 422 rotates the first part to be detected 101 of the second battery cell into the beam region, and the detection device 3 synchronously detects the fourth part to be detected 104 of the first battery cell and the first part to be detected 101 of the second battery cell.

[0093] The first transfer device 2 sequentially moves the first part to be detected 101, the second part to be detected 102, the third part to be detected 103, and the fourth part to be detected of the first battery cell into the beam region, completing the detection of the four parts to be detected. Simultaneously, the second transfer device 4 sequentially moves the fourth part to be detected 104, the third part to be detected 103, the second part to be detected 102, and the first part to be detected of the second battery cell into the beam region, completing the detection of the four parts to be detected.

[0094] The first transfer device 2 moves one part to be detected of one battery cell 100 into the beam region, while the second transfer device 4 moves one part to be detected of the other battery cell 100 into the beam region. As a result, the detection device 3 can simultaneously detect two parts to be detected of the two battery cells 100, which is advantageous for improving detection efficiency.

[0095] As shown in Figure 1, in a selective embodiment, the transport device 1 comprises a first transport mechanism 11 and a second transport mechanism 12, with a predetermined gap between the end of the first transport mechanism 11 and the front of the second transport mechanism 12 suitable for the passage of radiation generated by the detection device 3. The first transport mechanism 11 is used to transport one battery cell 100 to a first gripping station corresponding to a first transport device 2, and the first transport mechanism 11 and the second transport mechanism 12 work together to transport another battery cell 100 to a second gripping station corresponding to a second transport device 4.

[0096] Specifically, the conveying device 1 comprises a first conveying mechanism 11 and a second conveying mechanism 12. The first conveying mechanism 11 and the second conveying mechanism 12 have the same structure, the first conveying mechanism 11 and the first transporting device 2 are arranged in order along the vertical direction, and the second conveying mechanism 12 and the second transporting device 4 are arranged in order along the vertical direction.

[0097] The first conveying mechanism 11 comprises a first drive roller, a first driven roller, and a first conveyor belt, the first conveyor belt being sleeve-mounted on the first drive roller and the first driven roller. The second conveying mechanism 12 comprises a second drive roller, a second driven roller, and a second conveyor belt, the second conveyor belt being sleeve-mounted on the second drive roller and the second driven roller. The first conveying surface of the first conveyor belt and the second conveying surface of the second conveyor belt are arranged on the same horizontal plane.

[0098] The first transport mechanism 11 and the second transport mechanism 12 are positioned on opposite sides of the detection device 3, with the end of the first transport mechanism 11 and the front of the second transport mechanism 12 facing each other, and a predetermined gap formed between the end of the first transport mechanism 11 and the front of the second transport mechanism 12. The cone-shaped profile surface of the radiation beam emitted from the radiation means 31 is located in this predetermined gap. After the radiation passes through the part of the battery cell 100 to be detected, it is directly received by the detector means 32. This effectively avoids interference between the transport device 1 and the imaging system, contributing to improved scan image quality and further improving detection accuracy.

[0099] The first transport mechanism 11 and the second transport mechanism 12 work together to transport the battery cell 100. After detection is complete, the first gripping mechanism 21 places the battery cell 100, which has been gripped by the first transport device 2, onto the first conveyor belt. As the first and second conveyor belts rotate, the battery cell 100 moves from the first conveyor belt to the second conveyor belt, and then further moves to the second gripping station via the second conveyor belt.

[0100] In the embodiment of the present invention, a predetermined gap is formed between the end of the first transport mechanism 11 and the front of the second transport mechanism 12. After the radiation passes through the battery cell 100, the radiation is directly received by the detector means 32, thereby effectively preventing the transport device 1 from interfering with the imaging system, which helps to improve the quality of the scanned image and further improves the detection accuracy.

[0101] As shown in Figure 1, in an optional embodiment, the conveying device 1 further comprises a first stopper mechanism 13 and / or a second stopper mechanism 14. The first stopper mechanism 13 is provided on the first conveying mechanism 11 and is used to stop one battery cell 100 at the first gripping station. The second stopper mechanism 14 is provided on the second conveying mechanism 12 and is used to stop the other battery cell 100 at the second gripping station.

[0102] Specifically, the conveying device 1 also includes a first stopper mechanism 13 and / or a second stopper mechanism 14. The first stopper mechanism 13 is positioned at a first position on the first conveying mechanism 11, where the first position corresponds to a first gripping station, and the second stopper mechanism 14 is positioned at a second position on the second conveying mechanism 12, where the second position corresponds to a second gripping station.

[0103] The first battery cell and the second battery cell move to a first and second position, respectively, according to the conveyor belt, the first stopper mechanism 13 stops the first battery cell at the first position, and the second stopper mechanism 14 stops the second battery cell at the second position. The first stopper mechanism 13 has a positioning function for the first battery cell, and the second stopper mechanism 14 has a positioning function for the second battery cell.

[0104] Next, the first transfer device 2 moves from the detection station to the first gripping station, grips the first battery cell, and transports it back to the detection station. Simultaneously, the second transfer device 4 moves from the detection station to the second gripping station, grips the second battery cell, and transports it back to the detection station.

[0105] The first stopper mechanism 13 and the second stopper mechanism 14 have the same structure, and the structure of the first stopper mechanism 13 will be described below.

[0106] The first stopper mechanism 13 comprises an extendable drive member and a stopper member. The extendable drive member is an extendable drive member. The extendable drive member may be a cylinder, a hydraulic cylinder, an electric push rod, etc. The extendable drive member may be installed on the support frame of the first conveying mechanism 11. The extendable end of the extendable drive member is connected to the stopper member. The stopper member may be a plate-shaped body. The stopper member is arranged horizontally, and the extension direction of the stopper member is perpendicular to the conveying direction.

[0107] The battery cell 100 moves to the first gripping station along the first conveyor belt, and the telescopic end of the telescopic drive member extends, moving the stopper member to the top of the first conveyor belt. The tray 200 contacts the stopper surface of the stopper member to stop the movement so that the battery cell 100 is positioned at the first gripping station.

[0108] It is necessary to move the battery cell 100 from the first conveyor belt to the second conveyor belt. When the retractable end of the retractable drive member is retracted, the stopper moves to the outside of the first conveyor belt, allowing the battery cell 100 to be moved from the first conveyor belt to the second conveyor belt.

[0109] The detection device 3 detects the first battery cell and the second battery cell, and the first transport mechanism 11 moves the next group of battery cells to the first position, while the first stopper mechanism 13 stops the next group of battery cells at the first position. The first stopper mechanism 13 functions as a stopper and buffer for the next group of battery cells, reducing the time it takes for the first and second battery cells of the next group to move to the first and second positions, respectively, which is advantageous in improving the detection efficiency of batch products.

[0110] Furthermore, the detection device 3 detects the two battery cells 100 gripped by the first gripping mechanism 21 and the second gripping mechanism 41, and battery cells 100 that do not need to be detected can be moved directly to the second conveyor belt from below the detection reference surface via the first conveyor belt. Thus, the battery cell detection system has both a 100% detection function and a random detection function.

[0111] As shown in Figure 5, the present invention also provides a detection method for a battery cell detection system. This detection method includes the following steps.

[0112] Step 101: Transport battery cell 100 to the gripping station. Step 102: Transport the battery cell 100 from the gripping station to the detection station.

[0113] Step 103: The part of the battery cell 100 to be detected is rotated to a predetermined position to detect the part of the battery cell 100 to be detected.

[0114] Specifically, the battery cell detection system comprises a transport device 1, a first transfer device 2, and a detection device 3, and the structures of the transport device 1, the first transfer device 2, and the detection device 3 are as described above.

[0115] The battery cell 100 to be detected moves to the gripping station according to the conveyor belt, the first gripping mechanism 21 grips the battery cell 100, the first moving mechanism 22 moves linearly along the first direction to move the battery cell 100 from the gripping station to the detection station, the first moving mechanism 22 moves vertically to move the battery cell 100 to the detection reference plane of the detection device 3, the first moving mechanism 22 rotates to rotate the part of the battery cell 100 to be detected into the beam region, and the radiating means 31 and the detector means 32 detect the part of the battery cell 100 to be detected.

[0116] Depending on the detection needs, the first moving mechanism 22 sequentially rotates one or more parts of the battery cell 100 to be detected within the beam region, and the detection device 3 sequentially detects one or more parts to be detected.

[0117] The first gripping mechanism 21 grips the battery cell 100. After the battery cell 100 is separated from the transport surface of the transport device 1, the first moving mechanism 22 adjusts the position and orientation of the battery cell 100, enabling detection of any part of the battery cell 100 to be detected. This is advantageous for improving detection flexibility and detection efficiency.

[0118] In an optional embodiment, transporting the battery cells 100 to a gripping station includes transporting one battery cell 100 to a first gripping station and transporting the other battery cell 100 to a second gripping station.

[0119] Transferring a battery cell 100 from a gripping station to a detection station includes transferring one battery cell 100 from a first gripping station to a detection station while transferring the other battery cell 100 from a second gripping station to a detection station.

[0120] Specifically, the battery cell detection system comprises a first transfer device 2 and a second transfer device 4, and the detection device 3 can simultaneously detect two battery cells 100.

[0121] The conveying device 1 is provided with two corresponding gripping stations, namely a first gripping station and a second gripping station, in the direction of transport. Two adjacent battery cells 100 are moved to the first gripping station and the second gripping station, respectively, according to the conveyor belt.

[0122] Two adjacent battery cells 100 are transported to a first gripping station and a second gripping station, respectively. The first transfer device 2 and the second transfer device 4 transport the battery cells 100 from the first gripping station and the battery cells 100 from the second gripping station to the detection station in a synchronized manner, and since the two battery cells 100 are detected in a synchronized manner, the detection efficiency is improved.

[0123] In a selective embodiment, the transport device 1 comprises a first transport mechanism 11 and a second transport mechanism 12, wherein a predetermined gap suitable for the passage of radiation generated by the detection device 3 is formed between the end of the first transport mechanism 11 and the front of the second transport mechanism 12. The first transport mechanism 11 and the second transport mechanism 12 are located on opposite sides of the detection device 3.

[0124] The first conveyor belt of the first transport mechanism 11 rotates to transport one battery cell 100 to the first gripping station corresponding to the first transfer device 2. The first conveyor belt of the first transport mechanism 11 and the second conveyor belt of the second transport mechanism 12 rotate synchronously to transport the other battery cell 100 from the first conveyor belt to the second conveyor belt, and then move together with the second conveyor belt to the second gripping station corresponding to the second transfer device 4.

[0125] The end of the first transport mechanism 11 faces the front of the second transport mechanism 12, and a predetermined gap is formed between the end of the first transport mechanism 11 and the front of the second transport mechanism 12. The cone-shaped profile surface of the radiation beam emitted from the radiating means 31 is located in this predetermined gap. Since the radiation is received directly by the detector means 32 after passing through the part of the battery cell 100 to be detected, interference between the transport device 1 and the imaging system can be effectively avoided.

[0126] The first transport mechanism 11 and the second transport mechanism 12 work together to transport the battery cell 100. Furthermore, by providing a predetermined gap between the first transport mechanism 11 and the second transport mechanism 12, interference with the imaging system of the detection device 3 can be effectively avoided, which helps to improve the quality of the scanned image and also helps to improve the detection accuracy.

[0127] In a selective embodiment, detecting the part of the battery cell 100 to be detected by rotating it to a predetermined position includes the following: The first part to be detected 101 and the second part to be detected 102 of the battery cell 100, which is gripped by the first transfer device 2, are rotated sequentially to predetermined positions, and the first part to be detected 101 and the second part to be detected 102 are detected in sequence; Simultaneously, the third detection part 103 and the fourth detection part 104 of the other battery cell 100, which is gripped by the second transfer device 4, are rotated sequentially to predetermined positions, and the third detection part 103 and the fourth detection part 104 are detected in sequence.

[0128] Here, the part to be detected of any one of the battery cells 100 gripped by the first transfer device 2 and the part to be detected of any one of the other battery cells 100 gripped by the second transfer device 4 are detected synchronously.

[0129] Specifically, the transport device 1 transports the first battery cell to the first gripping station, the first transfer device 2 moves to the first gripping station, the first gripping mechanism 21 grips the first battery cell, the first linear motion mechanism 221 moves the first battery cell to the detection station by horizontal linear motion, the first lifting mechanism 222 moves the first battery cell to the detection reference plane by lifting motion, the first rotation mechanism 223 rotates the first part to be detected 101 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the first part to be detected 101. Next, the first rotation mechanism 223 rotates the second part to be detected 102 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the second part to be detected.

[0130] After the first detection unit 101 and the second detection unit 102 are detected, the first lifting mechanism 222 drives the first battery cell down to a point close to the conveying surface of the conveyor belt, the first gripping mechanism 21 places the first battery cell on the conveyor belt, and the first battery cell moves to the second gripping station together with the conveyor belt.

[0131] The second transfer device 4 moves to the second gripping station, the second gripping mechanism 41 grips the first battery cell, the first linear motion mechanism 221' moves the first battery cell to the detection station by horizontal linear motion, the second lifting mechanism 421 moves the first battery cell to the detection reference plane by lifting motion, the second rotating mechanism 422 rotates the third part to be detected 103 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the third part to be detected 103. Next, the second rotating mechanism 422 rotates the fourth part to be detected 104 of the first battery cell into the beam region by rotational motion, and the detection device 3 detects the fourth part to be detected 104.

[0132] It can be understood that when the first battery cell moves to the second gripping station, the second battery cell moves to the first gripping station together with the conveyor belt, and at the same time that the second gripping mechanism 41 grips the first battery cell at the second gripping station, the first gripping mechanism 21 grips the second battery cell at the first gripping station.

[0133] As the second moving mechanism 42 moves the first battery cell from the second gripping station to the detection station, the first moving mechanism 42 moves the second battery cell from the first gripping station to the detection station. The second rotating mechanism 422 rotates the third part to be detected 103 of the first battery cell into the beam region by rotational motion, and at the same time, the first rotating mechanism 223 rotates the first part to be detected 101 of the second battery cell into the beam region by rotational motion, and the detection device 3 synchronously detects the third part to be detected 103 of the first battery cell and the first part to be detected 101 of the second battery cell. Similarly, the detection device 3 synchronously detects the fourth part to be detected 104 of the first battery cell and the second part to be detected 102 of the second battery cell.

[0134] The first transfer device 2 sequentially moves the first part to be detected 101 and the second part to be detected 102 of the battery cell 100 into the beam region and completes the detection of the first part to be detected 101 and the second part to be detected 102. The second transfer device 4 sequentially moves the third part to be detected 103 and the fourth part to be detected 104 of the battery cell 100 into the beam region and completes the detection of the third part to be detected 103 and the fourth part to be detected 104.

[0135] The first transfer device 2 moves one part of one battery cell 100 to be detected into the beam region, and the second transfer device 4 moves the other part of the battery cell 100 to be detected into the beam region. The detection device 3 is advantageous in improving detection efficiency because it detects two parts of the two battery cells 100 simultaneously.

[0136] In a selective embodiment, the step of rotating the part of the battery cell 100 to be detected to a predetermined position and detecting the part of the battery cell 100 to be detected includes the following steps.

[0137] The first part to be detected 101, the second part to be detected 102, the third part to be detected 103, and the fourth part to be detected 104 of one battery cell 100 held by the first transfer device 2 are rotated in order to predetermined positions, and the first part to be detected 101, the second part to be detected 102, the third part to be detected 103, and the fourth part to be detected 104 are detected in order.

[0138] Simultaneously, the fourth part to be detected 104, the third part to be detected 103, the second part to be detected 102, and the first part to be detected 101 of the other battery cell 100, which is gripped by the second transfer device 4, are rotated in order to their predetermined positions, and the fourth part to be detected 104, the third part to be detected 103, the second part to be detected 102, and the first part to be detected 101 are detected in order.

[0139] Here, any part to be detected on one battery cell 100 held by the first transfer device 2 and any part to be detected on the other battery cell 100 held by the second transfer device 4 are detected synchronously.

[0140] Specifically, the transport device 1 transports the first battery cell to the first gripping station and the second battery cell to the second gripping station.

[0141] The first transfer device 2 moves to the first gripping station, and simultaneously the second transfer device 4 moves to the second gripping station. The first gripping mechanism 21 grips the first battery cell at the first gripping station, and the first moving mechanism 22 moves the first battery cell to the detection station. At the same time, the second gripping mechanism 41 grips the second battery cell at the second gripping station, and the second moving mechanism 42 moves the second battery cell to the detection station.

[0142] The first rotating mechanism 223 rotates the first part to be detected 101 of the first battery cell into the beam region, and the second rotating mechanism 422 rotates the fourth part to be detected 104 of the second battery cell into the beam region. The detection device 3 detects the first part to be detected 101 of the first battery cell and the fourth part to be detected 104 of the second battery cell in a synchronous manner.

[0143] Subsequently, the first rotating mechanism 223 rotates the second part to be detected 102 of the first battery cell into the beam region, and at the same time, the second rotating mechanism 422 rotates the third part to be detected 103 of the second battery cell into the beam region, so that the detection device 3 detects the second part to be detected 102 and the third part to be detected 103 of the first battery cell in a synchronous manner.

[0144] Subsequently, the first rotating mechanism 223 rotates the third part to be detected 103 of the first battery cell into the beam region, and at the same time, the second rotating mechanism 422 rotates the second part to be detected 102 of the second battery cell into the beam region, so that the detection device 3 synchronously detects the third part to be detected 103 of the first battery cell and the second part to be detected 102 of the second battery cell.

[0145] Subsequently, the first rotating mechanism 223 rotates the fourth part to be detected 104 of the first battery cell into the beam region, and at the same time, the second rotating mechanism 422 rotates the first part to be detected 101 of the second battery cell into the beam region, so that the detection device 3 synchronously detects the fourth part to be detected 104 of the first battery cell and the first part to be detected 101 of the second battery cell.

[0146] The first transfer device 2 moves the first part to be detected 101, the second part to be detected 102, the third part to be detected 103, and the fourth part to be detected of the first battery cell in sequence into the beam region, completing the detection of the four parts to be detected. Simultaneously, the second transfer device 4 moves the fourth part to be detected, the third part to be detected 103, the second part to be detected 102, and the first part to be detected 101 of the second battery cell in sequence into the beam region, completing the detection of the four parts to be detected.

[0147] The first transfer device 2 moves one part of one battery cell 100 to be detected into the beam region, and simultaneously the second transfer device 4 moves one part of the other battery cell 100 to be detected into the beam region. Since the detection device 3 detects both parts of the two battery cells 100 simultaneously, it is advantageous for improving detection efficiency.

Any changes or substitutions of the spirit and principles of the present invention shall be included within the scope of protection of this application. Accordingly, the scope of protection of this application should be based on the claims. [Explanation of Symbols]
