Technical Field

[0001] The present application generally relates to the field of battery detection technology. More specifically, the present application relates to a battery appearance detection device. Furthermore, the present application also relates to a battery appearance detection method. Background Art

[0002] In the battery production process, the surface of the battery needs to be inspected to ensure the battery's pass rate. The traditional battery appearance inspection method is usually carried out manually with an intermittent feeding mechanism and a roller fixture. The specific process is that the cylindrical battery is fed into the roller fixture by a manual or intermittent feeding mechanism, and then the roller fixture drives the battery to rotate under the drive of a rotating motor. During the rotation, the sampling camera triggers the image acquisition. After the image is acquired, the product is removed by a manual or intermittent material removal mechanism, thus completing an action cycle.

[0003] However, this traditional detection method has many shortcomings. First, the entire process requires frequent manual participation, which not only increases the labor intensity, but also makes the equipment's production capacity largely limited by the operator's proficiency and work speed. Secondly, the effect of manual discharge is greatly affected by the state of the personnel, and it is easy to make operational errors, resulting in unstable product quality and difficulty in meeting the increasingly stringent battery quality standards and market demands. In addition, the speed of manual discharge is slow, which affects the detection efficiency.

[0004] In view of this, there is an urgent need to provide a battery appearance inspection device and a battery appearance inspection method, so as to automatically inspect multiple batteries to improve the inspection efficiency. Summary of the invention

[0005] In order to at least solve the technical problems mentioned above, the present application proposes a battery appearance inspection device and inspection method with high inspection efficiency in multiple aspects.

[0006] In the first aspect, the present application provides a battery appearance inspection device, comprising: a mounting frame; a rotating mechanism, on which a plurality of batteries are mounted, and the batteries can rotate and revolve around the central axis of the rotating mechanism at the same time; an imaging mechanism, which comprises an adjustment structure and a camera arranged on the adjustment structure, wherein the adjustment structure is used to adjust the direction and / or height of the camera; a swing slide, which is arranged on the mounting frame; the adjustment structure is fixedly mounted on the swing slide, and the swing slide drives the camera to follow the movement of different target batteries; and a driving assembly, which is connected to the swing slide and drives the swing slide to swing on the mounting frame.

[0007] In some embodiments, the driving assembly includes: a main swing plate, which is transmission-connected to the swing slide and is a fan-shaped part arranged on the mounting frame, and a notch is arranged at the outer edge of the fan-shaped part; a conjugate cam, which is arranged in the notch, and the conjugate cam includes a main cam and a return cam, and the main cam is arranged above the return cam; and a driving mechanism, a driving shaft on the driving mechanism passes through the mounting frame and is connected to the conjugate cam, driving the conjugate cam to drive the main swing plate to rotate, and then driving the swing slide to swing.

[0008] In some embodiments, the first end of the inner edge of the fan-shaped member is rotatably connected to a support member disposed above the mounting frame, and the second end of the outer edge of the fan-shaped member has a protrusion disposed on the lower surface, and the mounting frame has a sliding groove adapted to the protrusion, and the protrusion slides in the sliding groove.

[0009] In some embodiments, a transmission gear is fixedly mounted on the upper surface of the main swing plate, and the gear on the transmission gear meshes with the gear on the swing slide for transmission.

[0010] In some embodiments, the upper surface of the mounting frame has an annular guide rail, and the swing slide has a slider protruding from its lower surface, and the slider slides in the annular guide rail.

[0011] In some embodiments, the swing slide has an arcuate side wall at at least one end away from the rotating mechanism, and the curvature of the arcuate side wall is the same as the curvature of the annular guide rail; the arcuate side wall has an extension portion extending away from the rotating mechanism, and the adjustment structure is arranged on the extension portion.

[0012] In some embodiments, the mounting frame has a limiting mechanism protruding from its upper surface, and the limiting mechanism is configured to limit the imaging mechanism.

[0013] In some embodiments, the limiting mechanism includes a first limiting member and a second limiting member that are spaced apart; and the extending portion is disposed between the first limiting member and the second limiting member.

[0014] In some embodiments, the extension portion is disposed on a side of the annular guide rail away from the rotating mechanism.

[0015] In a second aspect, the present application provides a method for detecting battery appearance, which uses the above-mentioned battery appearance detection device to detect the battery appearance, wherein the swing speed of the swing slide is configured to be adjusted accordingly according to the rotation speed of the rotating mechanism to meet different production efficiencies.

[0016] Through the battery appearance inspection device provided as above, the rotating mechanism in the embodiment of the present application can not only make the battery rotate on its own, but also make the battery revolve around the central axis. And because a swinging slide is provided on the frame, the swinging slide can drive the imaging mechanism to move with the revolution of the battery. After photographing the outer surface of a battery, it swings to the initial position to continue photographing the surface condition of the next battery. This solution avoids the cumbersome steps of placing another battery on a roller fixture for further inspection after inspecting one battery in the traditional method, thereby greatly shortening the inspection time and significantly improving the inspection efficiency.

[0023] The specific implementation of the present application is described in detail below with reference to the accompanying drawings.

[0024] The present application provides a battery appearance inspection device, comprising: a mounting frame; a rotating mechanism, on which a plurality of batteries are mounted, and the batteries can rotate and revolve around the central axis of the rotating mechanism at the same time; an imaging mechanism, which comprises an adjustment structure and a camera arranged on the adjustment structure, wherein the adjustment structure is used to adjust the orientation and / or height of the camera; a swing slide, which is arranged on the mounting frame; the adjustment structure is fixedly mounted on the swing slide, and the swing slide drives the camera to follow the movement of different target batteries; and a driving assembly, which is connected to the swing slide and drives the swing slide to swing on the mounting frame.

[0025] like Figure 1 and Figure 2 As shown, in this solution, the battery appearance inspection device 100 includes a mounting frame 10 and a driving assembly 50, as well as a rotating mechanism 20, an imaging mechanism 30 and a swinging slide 40 arranged above the mounting frame 10. Next, the various structures of the battery appearance inspection device 100 are introduced.

[0026] The mounting frame 10 in this solution includes a plate-shaped member with a preset thickness, which is mainly used to support other structures on the battery appearance inspection device 100 .

[0027] The mounting frame 10 is provided with a rotating mechanism 20, which has a plurality of mounting seats for placing batteries, and these mounting seats are arranged in a circular shape. The batteries can rotate on their respective mounting seats, and at the same time, the rotation of the rotating mechanism 20 can also drive these mounting seats to perform circular motion around their own central axis, thereby realizing the revolution of the batteries. In this way, the batteries can perform the revolution motion while rotating on themselves.

[0028] The mounting frame 10 is also provided with a swinging slide 40, on which an imaging mechanism 30 is also fixedly mounted. Specifically, the swinging slide 40 is a plate structure in a fan shape and has a preset thickness. The imaging mechanism 30 includes an adjustment structure 31 and a camera 32 arranged on the adjustment structure 31. The adjustment structure 31 includes a support rod with a preset height and a mounting structure arranged on the support rod, one end of the support rod is fixedly mounted on the swinging slide 40, and the other end is extended away from the swinging slide 40. The camera 32 is fixed on the mounting structure on the support rod. During use, in order to match batteries of different sizes, the height of the camera 32 can be adjusted by adjusting the position of the mounting structure in the height direction of the support rod. In addition, in addition to the height adjustment, the adjustment structure 31 in the imaging mechanism 30 can also adjust the direction of the camera 32, so that the camera 32 can change its shooting angle. By adjusting the adjustment structure 31, the camera 32 can be accurately aligned with the target area, thereby improving the accuracy and flexibility of the detection.

[0029] Those skilled in the art will appreciate that, since the swing slide 40 needs to swing on the upper surface of the mounting frame 10, it is not fixedly mounted on the mounting frame 10 by fasteners, but is rotatably connected to the mounting frame by a rotating shaft.

[0030] The battery appearance inspection device 100 provided in this solution, in addition to the structure described above, also has a driving assembly 50. The driving assembly 50 is connected to the swinging slide 40, and drives the swinging slide 40 to swing back and forth on the mounting frame 10, so that the swinging slide 40 drives the camera 32 on the adjustment structure 31 to follow the movement of different target batteries. Specifically, in this solution, the battery being inspected on the rotating mechanism 20 is defined as the target battery, and the revolution direction of the battery is defined as the first direction, wherein the first direction can be clockwise or counterclockwise. When the target battery is inspected, the driving assembly 50 drives the swinging slide 40 to move along the first direction. At the same time, the target battery rotates on the mounting seat while also revolving with the rotating mechanism 20. When the target battery rotates one circle, the camera 32 on the swinging slide 40 completes the inspection of the target battery, and then the swinging slide 40 stops moving along the first direction with the target battery, and then moves along the second direction under the drive of the driving assembly 50 and returns to its initial position, preparing for the inspection of the next target battery, until all target batteries are inspected.

[0031] In the solution of the present application, the battery can not only rotate on its own, but also revolve around the central axis, so that the camera 32 can capture the full range of images of the battery without adjusting the battery position multiple times, which greatly shortens the detection time and improves the detection efficiency. In addition, the battery on the swing slide 40 can also revolve, so that the camera 32 can return to the initial position after detecting a target battery and continue to detect the appearance defects of another target battery without manual intervention, thus realizing the automation of the detection process, reducing the dependence on manual operation, reducing human errors, and improving the stability and consistency of detection.

[0032] The connection relationship and function of the driving assembly 50 are introduced in the above disclosed content, and the specific structure of the driving assembly 50 is described in detail below.

[0033] In a specific embodiment, the driving assembly 50 includes: a main swing disk 51, which is transmission-connected to the swing slide 40 and is a fan-shaped part arranged on the mounting frame 10, and a notch is arranged at the outer edge of the fan-shaped part; a conjugate cam 53, which is arranged in the notch, and the conjugate cam includes a main cam and a return cam, and the main cam is arranged above the return cam; and a driving mechanism 55, a driving shaft on the driving mechanism 55 passes through the mounting frame 10 and is connected to the conjugate cam 53, driving the conjugate cam 53 to drive the main swing disk 51 to rotate, and then driving the swing slide 40 to swing.

[0034] The first end of the inner edge of the fan-shaped member is rotatably connected to a support member arranged above the mounting frame 10, and the second end of the outer edge of the fan-shaped member has a protrusion arranged on the lower surface. The mounting frame 10 has a sliding groove 11 adapted to the protrusion, and the protrusion slides in the sliding groove 11.

[0035] In this solution, the driving assembly 50 includes a main swing plate 51, a conjugate cam 53 and a driving mechanism 55. The main swing plate 51 and the conjugate cam 53 are installed above the mounting frame 10, and the driving mechanism 55 is arranged below the mounting frame 10. The driving shaft on the driving mechanism 55 passes through the mounting frame 10 and is connected to the conjugate cam 53. Specifically, the main swing plate 51 is a fan-shaped member, which has an inner edge and an outer edge, and the arc length of the inner edge is less than the arc length of the outer edge. The first end of the inner edge of the fan-shaped member is connected to the support member above the mounting frame 10 by a rotation connection. This design enables the fan-shaped member to rotate freely under the support of the support member. At the second end of the outer edge of the fan-shaped member, there is a protrusion arranged on the lower surface. The upper surface of the mounting frame 10 is correspondingly provided with a sliding groove 11 adapted to the protrusion, and the protrusion slides in the sliding groove 11. This sliding design not only provides a guide for the rotation of the fan-shaped member, but also can bear and disperse the force generated during the rotation process, ensuring the stability and reliability of the drive assembly 50. In addition, a notch is specially provided at the outer edge of the main swing plate 51, and this notch provides space for the installation and movement of the conjugate cam 53. In this solution, the outer edge of the main swing plate 51 is also connected to the swing slide 40 through a gear transmission. In other words, the conjugate cam 53 drives the main swing plate 51 to swing, and the main swing plate 51 drives the swing slide 40 to swing back and forth.

[0036] In this solution, the conjugate cam 53 is installed in the notch of the main swing plate 51, and is composed of a main cam and a return cam, wherein the main cam is located above the return cam. The design of the conjugate cam 53 is the core of the drive assembly 50, and through the rotational motion of the cam, the rotational motion can be converted into the swinging motion of the main swing plate 51. The shape and size of the conjugate cam 53 are carefully designed to ensure that its cooperation with the main swing plate 51 can achieve smooth and accurate swinging.

[0037] like Figure 1 and Figure 3 As shown, in this solution, the driving mechanism 55 is the power source of the driving assembly 50. The driving mechanism 55 and other structures are arranged below the mounting frame 10, and the driving shaft on the driving mechanism 55 passes through the mounting frame 10 and is connected to the conjugate cam 53. When the driving mechanism 55 is started, it drives the conjugate cam 53 to rotate, thereby driving the main swing plate 51 to rotate. Since the main swing plate 51 is connected to the swing slide 40, the swing slide 40 will also swing accordingly, thereby realizing the tracking shooting of different target batteries by the imaging mechanism 30.

[0038] It is worth noting that in this solution, a certain preset height is maintained between the mounting frame 10 and the horizontal plane, which not only provides a suitable installation position for the driving mechanism 55 in the driving assembly 50, but also provides sufficient space for the power system (not shown in the figure) that drives the rotating mechanism 20 to rotate, so that it can also be arranged under the mounting frame 10. Such a layout makes the structure of the entire device more compact and is conducive to optimizing space utilization.

[0039] It is also worth mentioning that this solution achieves precise matching of gapless transmission between the two by flexibly adjusting the trajectory of the conjugate cam 53 and the structure of the main swing disk 51. On the one hand, the contour curves of the main cam and the return cam can be adjusted to match the motion trajectory of the main swing disk 51, ensuring that the cam can accurately and smoothly transmit motion when pushing the main swing disk. On the other hand, the main swing disk 51 can also be adjusted accordingly according to the contour curves of the main cam and the return cam to further optimize its contact relationship with the cam and enhance the stability and accuracy of the transmission. Through this two-way adjustment mechanism, this solution can effectively eliminate the gap in the transmission process, improve the transmission efficiency and reliability, and provide a strong guarantee for the efficient operation of the battery appearance detection device.

[0040] The battery appearance inspection device provided by the present solution converts the rotational motion of the driving mechanism 55 into the constant speed swing of the swinging slide 40 through the design of the conjugate cam 53 mechanism, ensuring that the camera 32 follows the battery movement at a constant speed during the shooting process, thereby obtaining a clear and stable image. At the same time, the device does not require a complex electrical control system, simplifies the control process, reduces costs and failure risks, improves reliability and stability, makes operation and maintenance easier, and reduces the technical requirements for operators.

[0041] The above scheme discusses that the main swing plate 51 in the driving assembly 50 is directly connected to the swing slide 40. In order to further improve the transmission accuracy and the stability of the power, in one embodiment, a transmission gear 54 is specially provided. The structure and installation position of the transmission gear 54 are described in detail below.

[0042] In a specific embodiment, a transmission gear 54 is fixedly mounted on the upper surface of the main swing plate 51 , and the gear on the transmission gear 54 meshes with the gear on the swing slide 40 for transmission.

[0043] In this embodiment, a transmission gear 54 is fixedly mounted on the upper surface of the main swing plate 51, and the transmission gear 54 is a key transmission component connecting the main swing plate 51 and the swing slide 40. The tooth shape of the transmission gear 54 matches the gear on the swing slide 40, and the two transmit the rotational motion of the main swing plate 51 to the swing slide 40 through meshing transmission, thereby driving the swing slide 40 to achieve swing motion.

[0044] In addition, in order to eliminate the gear transmission gap, the transmission gear 54 of this scheme adopts a double-piece thin-tooth clearance elimination method. Specifically, the transmission gear 54 is composed of two thin-tooth gears, and the tooth profiles of the two thin-tooth gears are the same, but the tooth thickness is slightly different. During installation, the two thin-tooth gears are installed side by side on the upper surface of the main swing plate 51, and their tooth surfaces are tightly fitted together to form a whole. When the transmission gear 54 is meshed with the gear on the swing slide 40, the tooth surfaces of the two thin-tooth gears are in contact with the tooth surfaces of the gears of the swing slide 40 respectively. Due to the difference in tooth thickness, the two thin-tooth gears will squeeze each other during the meshing process, thereby eliminating the gap between them.

[0045] Through the double-plate thin-tooth clearance elimination method, the meshing between the gear on the transmission gear 54 and the gear on the swing slide 40 is tighter, the transmission error is effectively controlled, the transmission accuracy is improved, and the swing slide 40 is ensured to swing according to the predetermined trajectory and speed. At the same time, this clearance elimination method can also reduce the vibration and noise in the gear transmission process, extend the service life of the gear, improve the transmission efficiency and stability, and provide a strong guarantee for the efficient and stable operation of the battery appearance inspection device 100.

[0046] The above scheme describes the relevant information of the driving assembly 50 in detail, and the relevant information of the swing slide 40 is described in detail next.

[0047] In a specific embodiment, the upper surface of the mounting frame 10 has an annular guide rail 12, and the swing slide 40 has a slider protruding from its lower surface, and the slider slides in the annular guide rail 12. The swing slide 40 has an arc-shaped side wall at least at one end away from the rotating mechanism 20, and the curvature of the arc-shaped side wall is the same as the curvature of the annular guide rail 12; the arc-shaped side wall has an extension portion 41 extending away from the rotating mechanism 20, and the adjustment structure 31 is arranged on the extension portion 41. The mounting frame 10 has a limiting mechanism 60 protruding from its upper surface, and the limiting mechanism is configured as a limiting mechanism 60 for limiting the imaging mechanism 30. The limiting mechanism 60 includes a first limiting member 61 and a second limiting member 62 arranged at intervals; the extension portion 41 is arranged between the first limiting member 61 and the second limiting member 62. The extension portion 41 is arranged on the side of the annular guide rail 12 away from the rotating mechanism 20.

[0048] In this solution, since the swing slide 40 is a fan-shaped plate structure with a preset thickness, the swing slide 40 has an arc-shaped side wall at the end away from the rotating mechanism 20, and the curvature of the arc-shaped side wall is the same as the curvature of the annular guide rail 12, so that the swing slide 40 can maintain a good matching relationship with the annular guide rail 12 during the swinging process, further enhancing the stability and consistency of the movement. In addition, the arc-shaped side wall also has an extension portion 41 extending in a direction away from the rotating mechanism 20, and the adjustment structure 31 is arranged on the extension portion 41.

[0049] In addition, the upper surface of the mounting frame 10 is designed with an annular guide rail 12, the shape of which matches the motion trajectory of the swing slide 40, providing guidance and support for the sliding of the swing slide 40. The swing slide 40 has a slider protruding from its lower surface, which matches the annular guide rail 12 on the mounting frame 10 and can slide freely in the annular guide rail 12. When the swing slide 40 swings under the action of the driving assembly 50, the slider slides along the trajectory of the annular guide rail 12, thereby ensuring that the swing slide 40 moves smoothly and accurately, avoiding deviation or jamming. This design improves the movement stability of the swing slide 40.

[0050] In this solution, in order to limit the motion stroke of the imaging mechanism 30, a limiting mechanism 60 protruding from the upper surface of the mounting frame 10 is also provided. Specifically, the limiting mechanism 60 in this solution is to limit the extension portion 41, thereby indirectly realizing the effective limiting of the imaging mechanism 30. It is worth noting that the extension portion 41 in this solution is arranged on the mounting frame 10 on the side of the annular guide rail 12 away from the rotating mechanism 20. At the same time, the limiting mechanism 60 is also arranged on the mounting frame 10 on the side of the annular guide rail 12 away from the rotating mechanism 20. More specifically, the limiting mechanism 60 in this solution includes a first limiting member 61 and a second limiting member 62 arranged at intervals, and the extension portion 41 is arranged between the first limiting member 61 and the second limiting member 62, so that during the swinging process of the swinging slide 40, the limiting mechanism 60 can effectively limit the imaging mechanism 30, prevent it from swinging excessively or deviating from the predetermined motion trajectory, and ensure the reliability and accuracy of the detection process.

[0051] The first stopper 61 and the second stopper 62 in this solution both include a mounting portion arranged on the mounting frame 10 along the vertical direction, and a blocking portion extending along the horizontal direction. Specifically, a through hole extending along a fixed direction is provided on the mounting portion, and the blocking portion is inserted into the through hole and fixed on the mounting portion. More specifically, an internal thread is provided on the inner peripheral wall of the through hole, and an external thread is provided on the outer periphery of the blocking portion, and the two are threadedly connected. The advantage of such a setting is that the distance between the two blocking portions can be easily adjusted, thereby adjusting the swing range of the imaging mechanism 30.

[0052] In a specific embodiment, a limiting groove is provided on the side of the extension portion 41 facing the limiting mechanism 60, and the limiting groove is used to prevent accidental impact and also plays a buffering role.

[0053] It can be understood by those skilled in the art that the present invention does not limit the specific structures of the first limiting member 61 and the second limiting member 62. The two can be configured as shown in the attached figure. Figure 1 and attached Figure 2 The structural form shown in the figure can also be designed as two cylindrical structures on the upper surface of the mounting frame 10, and the two cylindrical structures can adjust their installation positions on the mounting frame. The flexibility of this design allows the most suitable limiter structure to be selected according to actual application requirements and spatial layout to achieve effective limit of the imaging mechanism 30.

[0054] It is worth noting that the annular guide rail 12 in the present scheme is an HSR annular guide rail, where HSR refers to the model of the annular guide rail, that is, a full steel spherical guide rail. The design and structure of the HSR annular guide rail are relatively standardized, and the installation and debugging process is relatively simple. During the assembly process of the device, it is only necessary to fix it in the specified position according to the installation requirements of the guide rail, and then connect the slider on the swing slide 40 to the guide rail. Furthermore, HSR annular guide rails of different specifications have good interchangeability. When the device needs to upgrade or replace the guide rail, guide rails of other specifications can be selected for replacement without large-scale changes to the entire device. Components such as sliders on the HSR annular guide rail are also interchangeable. When a component is worn or damaged, a new component can be quickly replaced without replacing the entire guide rail, which reduces maintenance costs and improves the maintainability of the device. Furthermore, the manufacturing process of the HSR annular guide rail is advanced, and the surface smoothness and dimensional accuracy of the guide rail are very high, which makes the movement of the imaging mechanism 30 on the guide rail have a high rotational accuracy.

[0055] The battery appearance inspection device provided by the present application drives the swing slide 40 to move through the conjugate cam 53, so that the camera 32 can automatically follow the movement of different target batteries without manual intervention, thereby realizing the automation of the inspection process. This not only reduces the dependence on manual operation and reduces human errors, but also avoids the cumbersome steps of placing another target battery on the roller fixture for further inspection after inspecting one target battery in the traditional method, thereby greatly shortening the inspection time and significantly improving the inspection efficiency.

[0056] In some embodiments, the present application provides a method for detecting the appearance of a battery, which uses the above-mentioned battery appearance detection device 100 to detect the appearance of the battery, and the method includes: the driving component 50 drives the swing slide 40 to swing, so that the camera 32 moves along the first direction at the initial position to follow the target battery for shooting, and after the shooting is completed, the camera 32 is controlled to move along the second direction back to the initial position to prepare for the detection of the next target battery.

[0057] When the camera 32 moves in the first direction at the initial position, the conjugate cam 53 is first controlled to accelerate to a preset speed with a modified sine curve, and then moves with a constant speed curve; when the camera 32 moves in the second direction at the initial position, the conjugate cam 53 is controlled to decelerate to the initial position with a modified sine curve.

[0058] In this solution, a method for detecting the appearance of a battery using the above-mentioned battery appearance detection device 100 is provided, and the method includes the following steps. First, the driving assembly 50 is started, and the conjugate cam 53 is driven to rotate, driving the transmission gear 54 on the main swing plate 51 to move, thereby causing the swing slide 40 to swing. In this process, the swing slide 40 drives the camera 32 to move in the first direction from the initial position. In order to enable the camera 32 to move smoothly and stably in the initial stage, the conjugate cam 53 controls the acceleration process of the camera 32 in the form of a modified sine curve in the initial stage. It is worth noting that the modified sine curve is a smooth acceleration curve, which can effectively reduce the impact and vibration of the camera 32 when it is started, so that the camera 32 gradually and smoothly accelerates to a preset speed. When the swing slide 40 reaches the preset speed, the conjugate cam 53 switches to the constant speed curve control mode, so that the camera 32 continues to move in the first direction at a constant speed, ensuring that the camera 32 can follow the battery at a stable rate during the shooting process, thereby obtaining a clear and continuous battery appearance image.

[0059] After completing the shooting of the target battery, the camera 32 is controlled to move in the second direction to return to the initial position. In this process, the conjugate cam 53 controls the deceleration movement of the camera 32 with a modified sine curve. It is worth noting that the modified sine curve is not only applicable to acceleration, but also to deceleration. It can make the camera 32 decelerate smoothly and avoid the impact caused by sudden stop that causes the camera to move. Through this precise deceleration control, the camera 32 can smoothly and accurately return to the initial position and prepare for the detection of the next target battery.

[0060] Those skilled in the art can understand that the present solution does not limit the motion trajectory of the swing slide 40 under two specific motion conditions controlled by the conjugate cam 53. Specifically, when the swing slide 40 is decelerating along the first direction, the conjugate cam 53 can use a modified sine curve or other curves to control its motion; similarly, when the swing slide 40 is accelerating along the second direction, the conjugate cam 53 can also use a modified sine curve or other curves to achieve control.

[0061] It is worth noting that in this solution, the battery being tested on the rotating structure is defined as the target battery, and the revolution direction of the battery is defined as the first direction, wherein the first direction can be clockwise or counterclockwise. In addition, this solution can also set different cam speeds to meet different testing requirements.

[0062] In a specific embodiment, the swing speed of the swing slide 40 in this solution is configured to be adjusted accordingly according to the rotation speed of the rotating mechanism 20 to meet different production efficiencies.

[0063] It is understood by those skilled in the art that different production scenarios have different requirements for the battery detection speed. On a high-speed production line, a large number of batteries need to be detected quickly, and the rotation speed of the rotating mechanism 20 will be increased. Accordingly, the swing speed of the swing slide 40 can be increased by adjusting the speed of the conjugate cam 53, so that the swing speed of the swing slide 40 matches the speed of the rotating mechanism 20.

[0064] On the contrary, in some occasions where the detection accuracy is extremely high, it is necessary to slow down the detection speed to obtain a clearer and more accurate image, and at this time the rotation speed of the rotating mechanism 20 will be reduced. Accordingly, the swing speed of the swing slide 40 can be reduced by adjusting the speed of the conjugate cam 53, so that the swing speed of the swing slide 40 matches the speed of the rotating mechanism 20.

[0065] That is to say, in this solution, the rotation speed of the conjugate cam 53 can be adjusted to thereby adjust the swing speed of the swing slide 40, so that the rotation speed of the entire swing slide 40 matches that of the rotating mechanism 20, thereby satisfying different production efficiencies.

[0066] In a specific embodiment, in order to match the detection requirements of different batteries, the swing range of the imaging mechanism 30 can be adjusted. Specifically, the swing range of the imaging mechanism is adjusted by adjusting the distance between the first limiter 61 and the second limiter 62. More specifically, the distance between the first limiter 61 and the second limiter 62 is adjusted by the distance between the blocking parts on the first limiter 61 and the second limiter 62.

[0067] The solution provided in this application realizes efficient and stable detection of battery appearance by camera 32. The coordinated work of driving assembly 50 and conjugate cam 53 ensures the accuracy and stability of the movement of camera 32, and improves the efficiency and accuracy of battery appearance detection.
