Those skilled in the art will be able to understand the specific meaning of the above terms in the present disclosure on a case-by-case basis.

[0028] Hereinafter, a detection device 100 and a detection method for detecting a battery core 200 according to an embodiment of the present disclosure will be described with reference to FIGS.

[0029] As shown in FIGS. 1 and 2, according to the detection device 100 of the embodiment of the first aspect of the present disclosure, the detection device 100 includes a support mechanism 10, a rotation mechanism 20, a transmission mechanism 30, and a detection mechanism .

[0030] However, the rotation mechanism 20 is provided in the support mechanism 10. The transmission mechanism 30 transmits the battery core 200. The detection mechanism 23 is provided in the rotation mechanism 20, and includes a radiation source 231 and a detector 232, which detect the battery core 200 in the transmission mechanism 30, and which rotate in the circumferential direction on the rotation mechanism 20.

[0031] Specifically, the rotation mechanism 20 is provided on the support mechanism 10, and the detection mechanism 23 is provided on the rotation mechanism 20. The detection mechanism 23 is circumferentially rotatable by the rotation mechanism 20, and the transmission mechanism 30 transmits the battery core 200. When the detection device 100 needs to detect the battery core 200, the transmission mechanism 30 first transmits the battery core 200 to a detection area, and the radiation source 231 and the detector 232 of the detection mechanism 23 rotate circumferentially on the rotation mechanism 20 to detect the battery core 200 located within the detection area. The detection area is the area between the connecting lines between the radiation source 231 and the detector 232, and the detection mechanism 23 can detect the battery core 200 in this area. By rotating circumferentially on the rotation mechanism 20, the detection mechanism 23 can detect the battery core 200 in multiple directions, thereby detecting the tab alignment status and tab welding status for each battery core 200, and the arrangement position and arrangement angle of the battery core 200 on the transmission mechanism 30 are not limited.

[0032] According to the detection device 100 of the embodiment of the first aspect of the present disclosure, the detection device 100 can improve detection quality and detection efficiency while relaxing the arrangement requirements of the battery core 200.

[0033] Optionally, the detection device further includes a detection control system, which includes a rotation mechanism 20 controlling a turntable 22 to rotate the radiation source 231 and the detector 232 at a certain angle to avoid the battery core 200.

[0034] In some embodiments, the rotation mechanism 20 includes a rotation stand 21 provided on the support mechanism 10, and a turntable 22 that is rotatable in a circumferential direction relative to the rotation stand 21, and that fixes a radiation source 231 and a detector 232 to the turntable 22.

[0035] Specifically, the rotation mechanism 20 is mounted on the support mechanism 10 via a rotation stand 21, and the rotation stand 21 can support a turntable 22, which can rotate circumferentially on the rotation stand 21. The radiation source 231 and the detector 232 are fixed to the turntable 22 and can rotate synchronously with the turntable 22. When detecting the battery core 200, the radiation source 231 and the detector 232 rotate circumferentially around the battery core 200 located within the detection area, and can emit and scan beams to the battery core 200 in multiple directions.

[0036] As a result, by rotating the radiation source 231 and the detector 232 in a circumferential direction using the turntable 22, the battery core 200 located in the detection area can be scanned in multiple directions, thereby improving the detection quality of the battery core 200.

[0037] As shown in FIG. 2, the rotation mechanism 20 further includes a rotation connector 24 that is provided between the rotation stand 21 and the turntable 22 and reduces the resistance between the rotation stand 21 and the turntable 22 so that the turntable 22 can rotate freely.

[0038] Here, the configuration of the rotary connector 24 is not limited, and the rotary connector 24 may be an assembly of a circular slide rail and a circular slide block, or may be a bearing provided between the rotary stand 21 and the turntable 22.

[0039] When the rotary connector 24 is a circular slide rail and a circular slide block, the circular slide rail is provided on one of the rotary stand 21 and the turntable 22, and the circular slide block is provided on the other of the rotary stand 21 and the turntable 22, so that by engaging the circular slide rail and the circular slide block with each other, the turntable 22 can be freely rotated on the rotary stand 21.

[0040] Optionally, the rotation mechanism 20 further includes a drive motor fixed on the rotation stand 21, a drive gear provided on the motor shaft of the drive motor, and a driven gear provided on the outside of the turntable 22, and the drive gear and the driven gear are meshed with each other. This allows the turntable 22 to rotate in the circumferential direction by the drive of the drive motor, further improving the detection efficiency of the battery core 200.

[0041] The driven gear may be the entire circumference of the external teeth provided on the outside of the turntable 22, or may be a part of the external teeth provided on the outside of the turntable 22. When the driven gear is the entire circumference of the external teeth provided on the outside of the turntable 22, the turntable 22 can be rotated continuously in the circumferential direction by driving the drive motor. On the other hand, when the driven gear is a part of the external teeth provided on the outside of the turntable 22, the turntable 22 can be rotated back and forth by a certain angle by driving the drive motor, and this can be selected according to actual needs.

[0042] Furthermore, since the radiation source 231 and the detector 232 move in the radial direction of the rotating disk 22, the radiation source 231 and the detector 232 are switched between the detection position and the avoidance position.

[0043] Specifically, the radiation source 231 and the detector 232 can move in the radial direction of the turntable 22, thereby allowing them to approach or move away from each other. When the radiation source 231 and the detector 232 are both close to the center of the turntable 22, they can move to a detection position. At this time, the distance between the radiation source 231 and the detector 232 is short, resulting in relatively high detection accuracy. When the radiation source 231 and the detector 232 are both far from the center of the turntable 22, they can move to an avoidance position. At this time, the distance between the radiation source 231 and the detector 232 is far enough that when the transmission mechanism 30 transmits the battery core 200 into the detection area, there is a risk that the edge corner of the battery core 200 will interfere with the detection mechanism 23. By switching the radiation source 231 and the detector 232 to the avoidance position, they can move away from the battery core 200, preventing damage to the battery core 200 and the detection mechanism 23.

[0044] This allows the radiation source 231 and the detector 232 to be switched between the detection position and the avoidance position, thereby ensuring detection accuracy and increasing the safety of detection.

[0045] In some embodiments, a moving mechanism 40 is provided between the rotation mechanism 20 and the support mechanism 10 to displace the rotation mechanism 20 relative to the support mechanism 10 .

[0046] Specifically, when the detection mechanism 23 detects the battery core 200, the specifications of the battery core 200 may differ depending on the product, and when detecting a battery core 200 with different specifications, the detection position also differs. Therefore, by providing a moving mechanism 40 between the rotation mechanism 20 and the support mechanism 10, the position of the rotation mechanism can be adjusted and it can accommodate the detection of battery cells 200 with different specifications.

[0047] This allows the types of battery cores 200 that the detection device 100 can detect to be increased, improving versatility and reducing the cost of detecting the battery cores 200.

[0048] Alternatively, the moving mechanism 40 may be configured as a rotation stage 41 , and the rotation mechanism 20 may be rotated relative to the support mechanism 10 by being supported by the rotation stage 41 .

[0049] Specifically, the installation of the rotation stage 41 allows the rotation mechanism 20 and the transmission mechanism 30 to form a certain angle. To improve detection efficiency, the edge corner of the battery core 200 is generally detected when detecting the battery core 200. A certain angle must be formed between the connecting line between the radiation source 231 and the detector 232 and the center line of the battery core 200. By rotating the rotation mechanism 20 at a certain angle using the rotation stage 41, the center line of the battery core 200 and the extension direction of the transmission mechanism 30 become parallel, thereby reducing the space dedicated to the battery cells 200 in the transmission mechanism 30. In this way, when arranging the battery core, two battery cells 200 can be connected and arranged from front to rear while maintaining a certain safe distance, and can be arranged on the transmission mechanism 30 with their corners aligned. This allows the detection mechanism 23 to simultaneously detect two sets of battery cells 200, improving detection efficiency.

[0050] Further optionally, the moving mechanism 40 is configured as a translation mechanism 42, and the rotation mechanism 20 can move in a first direction and a second direction supported by the translation mechanism 42. The first direction is parallel to the center of the rotation axis of the moving mechanism 40, and the second direction is perpendicular to the center of the rotation axis of the detection mechanism 23.

[0051] Specifically, the translation mechanism 42 allows the rotation mechanism 20 to move in a first direction and a second direction, thereby adjusting the relative position with respect to the transmission mechanism 30. When detecting the battery core 200, since the battery core 200 has different specifications, the detection position differs for each battery core 200. The translation mechanism 42 allows the detection area of ​​the detection mechanism 23 to be adjusted so that the edge corner of the battery core 200 is located within the detection area, further improving detection accuracy. In addition, when positional interference occurs between the detection mechanism 23 and the battery core 200, the translation mechanism 42 allows the detection mechanism 23 to avoid the battery core 200, improving detection safety.

[0052] Furthermore, a first slide rail is provided on the support mechanism 10 on a side closer to the translation mechanism 42, and a first slide block is provided on the translation mechanism 42 on a side closer to the support mechanism 10. The first slide rail and the first slide block slide together to cooperate, allowing the rotation mechanism 20 to move in a first direction. A second slide rail is provided on the translation mechanism 42 on a side closer to the rotation mechanism 20, and a second slide block is provided on the rotation mechanism 20 on a side closer to the translation mechanism 42. The second slide rail and the second slide block slide together to cooperate, allowing the rotation mechanism 20 to move in a second direction. Cooperation between the first slide rail and the first slide block and between the second slide rail and the second slide block allows the rotation mechanism 20 to move more smoothly, reducing the difficulty of operation.

[0053] In some embodiments, the transmission mechanism 30 extends parallel to the center of the rotation axis of the detection mechanism 23, or the positioning mechanism extends perpendicular to the center of the rotation axis of the detection mechanism 23.

[0054] Specifically, when the transmission mechanism 30 extends parallel to the center of the rotation axis of the detection mechanism 23, the transmission mechanism 30 can pass through the center of the rotation mechanism 20. When the transmission mechanism 30 extends perpendicular to the center of the rotation axis of the detection mechanism 23, the transmission mechanism 30 can transmit the battery core 200 to one side of the detection mechanism 23. The battery core 200 can be moved stepwise by the transmission mechanism 30. A plurality of battery cells 200 to be detected are spaced apart in the transmission mechanism 30. When the transmission mechanism 30 transmits the battery core 200 to the detection area, the transmission mechanism 30 stops, and the detection mechanism 23 rotates by the turntable 22 to detect the battery core 200. When detection is completed, the transmission mechanism 30 moves the battery core 200 out of the detection area, at which time the next battery core 200 to be detected can move into the detection area for detection.

[0055] This allows the battery core 200 to be detected continuously, and further improves the detection efficiency of the battery core 200.

[0056] Furthermore, the transmission mechanism 30 further includes a plurality of positioning modules 31 spaced apart, which can position the battery core 200. When the battery core 200 is placed on the transmission mechanism 30, the positioning modules 31 position the battery core 200, ensuring that the detected edge corners of each battery core 200 are all positioned appropriately. This ensures that when the transmission mechanism 30 moves the battery core 200 into the detection area, the detection edge corners of each battery core 200 are all positioned in the same position, further improving detection accuracy.

[0057] Optionally, the positioning module 31 includes a first positioning portion 311 and a second positioning portion 312, the first positioning portion 311 and the second positioning portion 312 being perpendicular to each other, and both the first positioning portion 311 and the second positioning portion 312 being fixed to the transmission mechanism 30, a positioning space being formed inside the corner formed by the first positioning portion 311 and the second positioning portion 312, the edge corner of the battery core 200 to be detected being positioned in the positioning space, and two adjacent sides of the battery core 200 abutting against the first positioning portion 311 and the second positioning portion 312 respectively.

[0058] Specifically, when the battery core 200 needs to be detected, the battery core 200 is placed on the transmission mechanism 30, and one edge corner of the battery core 200 is placed in the positioning space, and the two adjacent sides of the edge corner are respectively abutted against the first positioning portion 311 and the second positioning portion 312. At this time, the battery core 200 is fixed to the transmission mechanism 30. This method can position the battery core 200 and ensure the positioning regularity of the battery core 200.

[0059] As a result, when the edge angle of the battery core 200 is subsequently detected by the detection mechanism 23, it can be detected without adjusting the position of the battery core 200, and detection efficiency can be increased while ensuring detection accuracy.

[0060] It should be noted that the connection form between the positioning module 31 and the transmission mechanism 30 is not limited here, and for example, the positioning module 31 can be connected to the transmission mechanism 30 by adhesive bonding, screw fastening, or fastening, and can be selected according to actual needs.

[0061] Alternatively, the first positioning portion 311 and the second positioning portion 312 may be grooves or protrusions formed on the transmission mechanism 30, and when the battery core 200 is placed on the transmission mechanism 30, the edge corners of the battery core 200 can be inserted into the grooves or protrusions, thereby fixing the position of the battery core 200.

[0062] Optionally, when the positioning module 31 is fixed to the transmission mechanism 30, it has a predetermined angle between 0° and 75°.

[0063] For example, the predetermined angle may be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, or 75°, and may be set according to actual needs.

[0064] It should be noted that the number and installation location of the positioning modules 31 in the transmission mechanism 30 are not limited here. For example, the positioning modules 31 may be installed on the center line of the transmission mechanism 30 and spaced apart, or the positioning modules 31 may be installed in parallel on both sides of the center line of the transmission mechanism 30, and can be selected according to actual needs.

[0065] As can be seen, the arrangement of the battery core 200 in the transmission mechanism 30 varies depending on the installation mode of the positioning module 31.

[0066] When the positioning modules 31 are arranged on the center line of the transmission mechanism 30 and spaced apart at equal intervals, in order to ensure the detection quality of the battery cores 200 by the detection mechanism 23, the positioning modules 31 can be installed at a predetermined angle so that the detection mechanism 23 can detect the edge corners of the battery cores 200. The battery cores 200 are placed in the positioning space with their edge corners abutting the first positioning portion 311 and the second positioning portion 312, respectively. At this time, multiple battery cores 200 can be placed on the transmission mechanism 30 at equal intervals. For example, if the predetermined angle of the positioning modules 31 is 45°, the battery cores 200 will also be arranged at an inclination of 45° relative to the transmission mechanism 30. When the transmission mechanism 30 transmits the battery cores 200 to the detection area, the detection mechanism 23 can detect the edge corners of the battery cores 200 in the circumferential direction, further improving the detection accuracy.

[0067] When the positioning modules 31 are installed in parallel on both sides of the center line of the transmission mechanism 30, the positioning modules 31 can be arranged diagonally with a predetermined angle of 0°. In this way, two battery cores 200 can be fixed simultaneously. When a rotation stage 41 is installed in the detection device 100, the rotation stage 41 can be used to install the rotation mechanism 20 at a certain angle so that the detection mechanism 23 and the center of the transmission mechanism 30 form a certain angle. In this case, two battery cores 200 are installed in the transmission mechanism 30, and due to the constraints of the positioning modules 31, the two battery cores 200 are installed on both sides of the center line of the transmission mechanism 30 diagonally from head to tail. The detection mechanism 23 can detect the edge angles of the two battery cores 200 simultaneously, further improving detection efficiency.

[0068] 2 , in some embodiments, the rotation mechanism 20 further includes a position sensor 25 that detects the position of the battery core 200 in the transmission mechanism 30. The position sensor 25 can detect the position of the battery core 200 in the transmission mechanism 30. The position sensor 25 is signal-connected to the rotation mechanism 20. Before the transmission mechanism 30 transmits the battery core 200 and enters the detection area, the position sensor 25 performs detection. If the position sensor 25 detects that the position of the battery core 200 may soon interfere with the detection mechanism 23, it sends an avoidance signal to the rotation mechanism 20, causing the turntable 22 to drive the radiation source 231 and the detector 232 to stop rotating in the circumferential direction and avoid the battery core 200. If the position sensor 25 detects that the position of the battery core 200 will not interfere with the detection mechanism 23 or does not detect the battery core 200, the turntable 22 drives the radiation source 231 and the detector 232 to continue rotating in the circumferential direction.

[0069] This prevents the battery core 200 from colliding with the detection mechanism 23 when the battery core 200 is detected, thereby improving detection safety.

[0070] Here, the type of the position sensor 25 is not limited, and the position sensor 25 may be, for example, an optical position sensor 25, an ultrasonic position sensor 25, a light curtain sensor, or a camera.

[0071] When the position sensor 25 is an optical position sensor 25, a light beam is emitted by the transmitter. If the battery core 200 located in the transmission mechanism 30 interferes with the rotation mechanism 20, the light beam emitted from the transmitter touches the battery core 200 and is then reflected back to the optical position sensor 25. At this time, the sensor can calculate the distance between the rotation mechanism 20 and the battery core 200. If the distance between the two is smaller than a predetermined threshold, the optical position sensor 25 sends an avoidance signal to the rotation mechanism 20, causing the turntable 22 to stop the circumferential rotation of the radiation source 231 and the detector 232, and move away from the battery core 200. If the optical position sensor 25 does not receive a reflected signal, or if it receives a signal and calculates that the distance between the battery core 200 and the rotation mechanism 20 is equal to or greater than the predetermined threshold, the turntable 22 continues to drive the radiation source 231 and the detector 232 to rotate in the circumferential direction.

[0072] When the position sensor 25 is a light curtain sensor, the light curtain sensor can be installed upstream of the rotation mechanism 20 and near the transmission mechanism 30, and when the light curtain sensor detects that the light curtain is blocked, it sends an avoidance signal to the rotation mechanism 20, stopping the circumferential rotation of the radiation source 231 and the detector 232 to avoid the battery core 200, and when the light curtain sensor detects that the light curtain is not blocked, the turntable 22 continues to drive the circumferential rotation of the radiation source 231 and the detector 232.

[0073] When the position sensor 25 is a camera, the camera is mounted on the rotating stand 21 and can photograph the battery core 200 located on the transmission mechanism 30. By identifying the position of the battery core 200 in the image, it can determine whether the battery core 200 and the rotation mechanism 20 will interfere with each other. When it is calculated from the image taken by the camera that the battery core 200 is about to collide with the rotation mechanism 20, the camera sends an avoidance signal to the rotation mechanism 20, and the turntable 22 stops the circumferential rotation of the radiation source 231 and the detector 232 to avoid the battery core 200. When the battery core 200 does not appear in the image taken by the camera, or when it is calculated from the image taken by the camera that the battery core 200 will not collide with the rotation mechanism 20, the camera sends a signal to the turntable 22 mechanism, and the turntable 22 continues to drive the circumferential rotation of the radiation source 231 and the detector 232.

[0074] Here, the position of the position sensor 25 in the detection device 100 is not specifically limited, and it is sufficient that the position sensor 25 can detect whether the battery core 200 and the rotation mechanism 20 collide, and it can be installed as needed.

[0075] In some embodiments, the detection apparatus 100 further includes a screening mechanism 50 that transports the battery core 200 to a disposal area when the detection mechanism 23 detects that the battery core 200 is unacceptable.

[0076] Specifically, when the detection mechanism 23 detects that the battery core 200 is unqualified, the screening mechanism 50 transfers the unqualified battery core 200 to a disposal area. After the detection mechanism 23 detects the battery core 200, if the internal defect condition of the battery core 200 does not meet the requirement, the screening mechanism 50 can screen and transfer the unqualified battery core 200 to a disposal area on the transmission mechanism 30 so that the qualified battery core 200 can proceed to the next process. This can improve the detection efficiency of the detection device 100.

[0077] As can be understood, in the present disclosure, the detection device 100 and the corresponding detection system can perform one-to-one numbering of the battery cores 200 detected by the detection device 100, and when the screening mechanism 50 transports the rejected battery cores 200 to a disposal area, the detection system also deletes the numbers and images corresponding to the rejected battery cores 200.

[0078] That is, the battery core 200 is first transmitted by the transmission mechanism 30 and detected by the detection mechanism 23. If the detection mechanism 23 detects that the battery core 200 is unqualified, the screening mechanism 50 transfers the battery core 200 to a disposal area. At the same time, the number and image corresponding to the unqualified battery core 200 are also deleted from the detection system. If the battery core 200 passes the detection of the detection mechanism 23 and is determined to be acceptable, the acceptable battery core 200 is allowed to proceed to the next process. This reduces the system resource occupation rate and further improves the detection efficiency of the detection device 100.

[0079] According to a detection method for detecting a battery core 200 in an embodiment of the second aspect of the present disclosure, the detection method is applied to any one of the detection devices 100 in the above-mentioned embodiments, and the detection method includes placing the battery core 200 on a transmission mechanism 30, the transmission mechanism 30 transmitting the battery core 200, and the detection mechanism 23 detecting the battery core 200.

[0080] In some embodiments, when the battery core 200 is installed in the transmission mechanism 30, the battery core 200 is installed at a predetermined angle, which may be between 15° and 75°.

[0081] Specifically, if the battery core 200 is installed at a predetermined angle, the center line of the battery core 200 and the extension direction of the transmission mechanism 30 can form a certain angle, that is, the battery core 200 is arranged diagonally on the transmission mechanism 30, and in this way, when the transmission mechanism 30 moves the battery core 200 into the detection area, the edge corner of the battery core 200 can be positioned in the detection area.

[0082] This makes it possible to improve the detection effect and increase the detection efficiency of the detection device 100.

[0083] For example, the predetermined angle may be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, or 75°, and can be set according to actual needs.

[0084] Hereinafter, the detection method for the battery core 200 will be described with reference to specific embodiments of the present disclosure.

[0085] Example 1: As shown in FIG. 2, the battery core 200 is installed in the transmission mechanism 30 and positioned at a predetermined angle.

[0086] The rotating disk 22 rotates the radiation source 231 and the detector 232 in the circumferential direction, and at this time, the transmission mechanism 30 extends parallel to the center of the rotation axis of the detection mechanism 23, and the transmission mechanism 30 transmits the battery core 200.

[0087] The position sensor 25 detects the position of the battery core 200, and when it detects that the battery core 200 may collide with the rotation mechanism 20 when it enters the detection area, it transmits an avoidance signal to the rotation mechanism 20.

[0088] After receiving the avoidance signal from the position sensor 25 , the rotation mechanism 20 controls the turntable 22 to rotate the radiation source 231 and the detector 232 at a certain angle to avoid the radiation source 231 and the detector 232 from the battery core 200 .

[0089] The transmission mechanism 30 transmits the battery core 200 to the detection area.

[0090] The position sensor 25 detects the position of the battery core 200, and sends a signal to the rotation mechanism 20 if it does not detect the battery core 200 or if it detects that the position of the battery core 200 is such that it cannot collide with the rotation mechanism 20.
