Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The appearance inspection device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 4 and Figure 6 As shown, the appearance inspection device 100 according to an embodiment of the present utility model includes a frame 1, a turret mechanism 2 and an appearance inspection mechanism 3.

[0027] Among them, such as Figure 1 and Figure 2As shown, the turret mechanism 2 includes a rotating assembly 21, which is rotatably mounted on the frame 1. The rotating assembly 21 is used to hold the inspection piece 200, and the axis of the inspection piece 200 is spaced apart from that of the rotating assembly 21. Thus, during the inspection of the inspection piece 200 by the appearance inspection device 100 of this application, the inspection piece 200 can be rotated along with the rotating assembly 21 by rotation, which facilitates the appearance inspection mechanism 3 to perform appearance inspection on the inspection piece 200.

[0028] like Figure 2 and Figure 3 As shown, the appearance inspection mechanism 3 includes an appearance inspection sensor 31, which is rotatably disposed on the radial outer side of the turret mechanism 2. The rotation axis of the appearance inspection sensor 31 coincides with the rotation axis of the rotating assembly 21. The appearance inspection sensor 31 is used to inspect the appearance of the inspection piece 200.

[0029] Therefore, during the inspection of the inspection piece 200 by the appearance inspection device 100 of this application, the rotation axis of the appearance inspection sensor 31 is aligned with the rotation axis of the rotation assembly 21, so that the appearance inspection sensor 31 can move with the inspection piece 200. This ensures that the relative position between the appearance inspection sensor 31 and the inspection piece 200 is fixed, effectively reducing the imaging error caused by the change of viewing angle. This makes the data collected by the appearance inspection sensor 31 more comprehensive and accurate, and improves the inspection accuracy of the appearance inspection device 100.

[0030] Meanwhile, after the appearance inspection sensor 31 completes the inspection of a piece 200, the appearance inspection sensor 31 will return to the initial position to prepare for the arrival of the next piece 200, further saving manual or mechanical adjustment time, making the entire inspection process of the appearance inspection device 100 smoother and more efficient, thereby improving the overall production efficiency.

[0031] It should be noted that the test piece 200 can be the casing of a cylindrical or square battery. The casing can be made of steel. The appearance inspection device 100 inspects the appearance of the casing (such as detecting dents, scratches, indentations, coating defects, etc.).

[0032] According to the appearance inspection device 100 of this utility model embodiment, the turret mechanism 2 includes a rotating component 21, which is rotatably mounted on the frame 1. The rotating component 21 is used to place the inspection piece 200. The axis of the inspection piece 200 is spaced apart from that of the rotating component 21. The appearance inspection mechanism 3 includes an appearance inspection sensor 31, which is rotatably mounted on the radial outer side of the turret mechanism 2. The rotation axis of the appearance inspection sensor 31 coincides with the rotation axis of the rotating component 21. The appearance inspection sensor 31 is used to inspect the appearance of the inspection piece 200, so that the appearance inspection sensor 31 can move with the inspection piece 200, making the data collected by the appearance inspection sensor 31 more comprehensive and accurate, and improving the inspection accuracy of the appearance inspection device 100.

[0033] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the frame 1 has a support plate 11, and the appearance inspection mechanism 3 further includes a first drive assembly 32. The first drive assembly 32 is disposed on the support plate 11 and connected to the appearance inspection sensor 31, and is used to drive the appearance inspection sensor 31 to rotate.

[0034] Thus, the support plate 11 provides support for the first drive assembly 32, ensuring the stable installation of the first drive assembly 32, thereby enabling the first drive assembly 32 to drive the appearance inspection sensor 31 to rotate accurately and smoothly, so as to achieve high-precision inspection of the inspection piece 200.

[0035] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the first drive assembly 32 includes a first motor 321, a slide rail 322, and a first transmission assembly. The first motor 321 is mounted on the support plate 11, the slide rail 322 is mounted on the support plate 11, the slide rail 322 extends circumferentially along the axis of the rotating assembly 21, the appearance detection sensor 31 moves along the length of the slide rail 322, and the first transmission assembly is connected to both the output end of the first motor 321 and the appearance detection sensor 31.

[0036] Therefore, when the appearance inspection device 100 starts, the first motor 321 receives a control signal and starts working. The rotational motion of the first motor 321 is transmitted to the appearance inspection sensor 31 through the first transmission component, so that the appearance inspection sensor 31 moves along the length direction of the slide rail 322. During the process of the appearance inspection sensor 31 inspecting the inspection piece 200, since the slide rail 322 extends in the circumferential direction along the axis of the rotating component 21, the appearance inspection sensor 31 will rotate synchronously with the inspection piece 200 on the rotating component 21, thereby ensuring that the collected data is not distorted. After the appearance inspection sensor 31 has finished inspecting an inspection piece 200, the first motor 321 receives a control signal and rotates in the opposite direction to drive the appearance inspection sensor 31 to automatically return to the initial position along the slide rail 322, in preparation for the next inspection cycle.

[0037] Meanwhile, the first drive assembly 32 uses the slide rail 322 as the motion guide for the appearance inspection sensor 31, ensuring the smooth movement of the appearance inspection sensor 31 and effectively reducing the shaking and swaying that may be caused by rotation or movement. This further ensures the clarity and accuracy of the images acquired by the appearance inspection sensor 31. In addition, the first motor 321 directly drives the appearance inspection sensor 31 to reciprocate on the slide rail 322 through the first transmission assembly, making the structure of the first drive assembly 32 relatively simple, reliable, and easy to maintain.

[0038] It should be noted that the structure of the first transmission component in this application is not limited here, as long as it can realize the transmission connection between the first transmission component and the output end of the first motor 321 and the appearance detection sensor 31 respectively, so that the first motor 321 drives the appearance detection sensor 31 to move along the length direction of the slide rail 322.

[0039] For example, the first transmission component can be a combination of gear and rack. The output shaft of the first motor 321 is connected to a gear, and a rack is provided on the slide rail 322. The rack is an arc-shaped rack concentric with the slide rail 322. The appearance detection sensor 31 is fixed on the mechanism that meshes with the gear. When the first motor 321 rotates, it drives the gear to rotate. The meshing of the gear and the rack converts the rotational motion of the first motor 321 into the movement of the appearance detection sensor 31 along the length direction of the slide rail 322.

[0040] For example, the first transmission component can be a combination of pulleys and timing belts. An active pulley is installed on the output shaft of the first motor 321, and a passive pulley is installed at both ends or on the other side of the slide rail 322. The timing belt is wound around the active pulley and the passive pulley respectively. The appearance detection sensor 31 is fixed on the timing belt. When the first motor 321 rotates, the active pulley drives the timing belt to move, so that the appearance detection sensor 31 fixed on the timing belt moves along the length of the slide rail 322.

[0041] For example, such as Figure 2 and Figure 3 As shown, the first motor 321 is an arc linear motor. The rotor of the arc linear motor extends circumferentially as the output end rotating assembly 21. The first transmission assembly is a connecting plate fixedly connected to the rotor mover and connected to it. The first transmission assembly is provided with a slider that cooperates with the slide rail 322 for guiding movement along the slide rail 322. Thus, the stator of the first motor 321 is energized to generate thrust, which drives the rotor to move circumferentially along the rotating assembly 21, so that the rotor is transmitted to the appearance detection sensor 31 via the connecting plate, thereby enabling the appearance detection sensor 31 to move along the length direction of the slide rail 322.

[0042] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the appearance inspection device 100 also includes a lifting mechanism 4. The lifting mechanism 4 is mounted on the rotating assembly 21 and is used to drive the inspection piece 200 to move along the rotation axis of the rotating assembly 21.

[0043] Understandably, since the detection component 200 is placed on the rotating assembly 21 and rotates with the rotating assembly 21, the bottom or some side structures of the detection component 200 may be obscured by the rotating assembly 21 itself, causing the appearance inspection sensor 31 to be unable to fully detect the appearance of the detection component 200. Therefore, by driving the detection component 200 to move along the rotation axis of the rotating assembly 21 through the lifting mechanism 4, more of the detection component 200 is exposed within the field of view of the appearance inspection sensor 31, eliminating the blind spot and further improving the detection accuracy of the appearance inspection device 100.

[0044] In some embodiments of this utility model, such as Figures 6-11 As shown, the rotation axis of the rotating assembly 21 extends in the vertical direction. The rotating assembly 21 has a fixing groove 2111. The lower end of the detection piece 200 is adapted to be located in the fixing groove 2111. The lifting mechanism 4 includes a transmission shaft 41 and a second drive assembly 42. The transmission shaft 41 is movably disposed on the rotating assembly 21 in the vertical direction. The lower end of the transmission shaft 41 is provided with a clamping mechanism 412 for clamping the upper end of the detection piece 200. The second drive assembly 42 is disposed on the rotating assembly 21 and is used to drive the transmission shaft 41 to move up and down.

[0045] Therefore, the clamping mechanism 412 at the lower end of the drive shaft 41 clamps the detection piece 200, and the second drive assembly 42 drives the drive shaft 41 to move up and down, so that the drive shaft 41 drives the detection piece 200 to move up and down. This achieves the lifting mechanism 4 driving the detection piece 200 to move along the rotation axis of the rotating assembly 21, so that more of the detection piece 200 is exposed in the field of view of the appearance inspection sensor 31, effectively avoiding the obstruction of the detection piece 200 by the fixing groove 2111, and improving the detection accuracy of the appearance inspection device 100.

[0046] Furthermore, such as Figure 9 As shown, the rotating assembly 21 has a base 211 and a fixing groove 2111 is provided on the base 211. The base 211 is arranged vertically opposite to the transmission shaft 41 and is located below the transmission shaft 41, so that the lower end of the detection piece 200 can be placed in the fixing groove 2111 and cooperate with the transmission shaft 41 above to achieve clamping and positioning of the detection piece 200.

[0047] Furthermore, there are multiple bases 211, which are spaced apart along the circumferential direction of the rotating assembly 21. There are multiple drive shafts 41 corresponding to each base 211, and multiple second drive assemblies 42 corresponding to each drive shaft 41. Thus, through this arrangement, multiple detection elements 200 can be placed on the rotating assembly 21, thereby achieving the clamping and positioning of multiple detection elements 200, thereby improving detection efficiency.

[0048] In some embodiments of this utility model, such as Figures 4-7 , Figure 10 and Figure 11 As shown, the second drive assembly 42 includes a cam 421, which is mounted on the frame 1 and located above the rotating assembly 21. The outer peripheral wall of the cam 421 has a drive track 4211, which extends along the circumferential direction of the rotating assembly 21. The drive track 4211 includes at least one set of first track 4211a, second track 4211b and third track 4211c connected to each other in sequence. Along the rotation direction of the rotating assembly 21, the first track 4211a is inclined upward, the second track 4211b is horizontally arranged, and the third track 4211c is inclined downward. A mating part 411 is provided on the drive shaft 41, and the mating part 411 is movably disposed within the drive track 4211.

[0049] Specifically, when the rotating assembly 21 rotates, the mating part 411 located on the drive shaft 41 moves along the drive track 4211. When the mating part 411 enters the upwardly inclined first track 4211a, the drive shaft 41 drives the detection part 200 to move upward. At this time, the clamping mechanism 412 at the lower end of the drive shaft 41 clamps the detection part 200 so that the detection part 200 rises together, thereby lifting the detection part 200 from the fixed groove 2111.

[0050] When the mating part 411 enters the horizontally set second track 4211b, the drive shaft 41 and the detection part 200 will move stably at the same height after rising. At this time, the appearance inspection sensor 31 detects the detection part 200, which effectively reduces the shaking and swaying that may be caused by rotation or movement and avoids the blind spot caused by the obstruction of the fixing groove 2111, further improving the clarity and accuracy of the image acquired by the appearance inspection sensor 31.

[0051] After the appearance inspection sensor 31 completes the inspection of the inspection piece 200, the mating part 411 enters the downwardly inclined third track 4211c along the second track 4211b. Under the action of the drive track 4211, the mating part 411 moves downward along the track, so that the drive shaft 41 drives the inspection piece 200 down into the fixed groove 2111. The clamping mechanism 412 at the lower end of the drive shaft 41 can disengage from the inspection piece 200, and the inspection piece 200 is transferred to the subsequent station with the rotating assembly 21.

[0052] Thus, through the cooperation between the mating part 411 on the transmission shaft 41 and the drive track 4211 of the cam 421, the transmission shaft 41 moves up and down during the continuous rotation of the rotating assembly 21, thereby realizing the up and down movement of the detection part 200 and eliminating the detection blind zone caused by the obstruction of the fixing groove 2111.

[0053] In some embodiments of this utility model, such as Figure 5 , Figure 7 , Figure 9 , Figure 12 and Figure 13 As shown, a roller 4111 is fitted onto the mating part 411, and the roller 4111 is rotatably disposed within the drive rail 4211. It can be understood that the roller 4111 can convert sliding friction into rolling friction, thereby reducing frictional force and the resistance experienced by the drive shaft 41 as it moves along the drive rail 4211. This makes the entire lifting and lowering process of the drive shaft 41 smoother and more stable, extends the service life of the drive shaft 41, the mating part 411, and the drive rail 4211, and reduces maintenance frequency and costs.

[0054] In some embodiments of this utility model, such as Figure 7 and Figure 9 As shown, the lifting mechanism 4 also includes a reset elastic element 43, which is connected to the drive shaft 41 and the rotating assembly 21, and is used to drive the drive shaft 41 to move upward. Thus, when the mating part 411 on the drive shaft 41 enters the upwardly inclined first track 4211a, the elastic force of the reset elastic element 43 will assist the mating part 411 to move upward, making the upward process of the drive shaft 41 smoother and less strenuous, and reducing the wear of the cam 421 and the mating part 411.

[0055] Specifically, when the mating part 411 enters the downwardly inclined third track 4211c, the drive shaft 41 moves downward. At this time, the reset elastic element 43 is compressed or stretched to store elastic potential energy. When the mating part 411 enters the upwardly inclined first track 4211a in the next round, the cam 421 pushes the drive shaft 41 upward. At this time, the reset elastic element 43 releases the stored elastic potential energy and superimposes it with the driving force of the cam 421, thereby realizing the upward movement of the drive shaft 41 and lifting the detection element 200, so that the upward movement of the drive shaft 41 is smoother and less strenuous.

[0056] In some embodiments, such as Figure 12 and Figure 13 As shown, the clamping mechanism 412 includes a single-acting cylinder 4121 and a gripper 4122. The single-acting cylinder 4121 is connected to the lower end of the drive shaft 41, and the lower end of the piston rod of the single-acting cylinder 4121 is connected to the gripper 4122. When clamping is required, the lifting mechanism 4 drives the drive shaft 41 to move downward so that the gripper extends into the detection piece 200. The single-acting cylinder 4121 is vented, the piston rod extends, and the gripper 4122 opens and pushes against the inner wall of the detection piece 200 to achieve reliable clamping. In the clamping state, the drive shaft 41 can drive the detection piece 200 to complete lifting and rotation. Once the detection piece 200 has fallen back and is securely positioned in the fixed groove 2111, the controller shuts off the air supply to the single-acting cylinder 4121. Under the action of the built-in return spring in the single-acting cylinder 4121, the piston rod retracts, the gripper 4122 retracts and resets, releasing the clamping of the detection piece 200. The lifting mechanism 4 drives the rotating shaft to move downward, so that the gripper 4122 rises, thereby separating the transmission shaft 41 from the detection piece 200.

[0057] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the appearance inspection device 100 also includes a rotary drive mechanism 5. The rotary drive mechanism 5 is mounted on the rotating assembly 21 and is used to drive the inspection piece 200 to rotate relative to the rotating assembly 21.

[0058] It is understandable that, since the rotation axis of the appearance inspection sensor 31 coincides with the rotation axis of the rotation component 21, and the rotation drive mechanism 5 causes the inspection piece 200 to rotate relative to the rotation component 21, under the condition that the radial distance and relative angle between the inspection piece 200 and the sensor remain constant, the appearance inspection sensor 31 can collect different outer surfaces of the inspection piece 200. This results in more complete, uniform, and blind-zone-free appearance data collected by the appearance inspection sensor 31 from the inspection piece 200, improving inspection accuracy and effectively shortening the inspection cycle of a single inspection piece 200, thereby improving the inspection efficiency of the appearance inspection device 100.

[0059] At the same time, such as Figures 8-11As shown, the appearance inspection device 100 also includes a lifting mechanism 4. The lifting mechanism 4 is mounted on the rotating assembly 21 and is used to drive the inspection piece 200 to move along the rotation axis of the rotating assembly 21. Thus, by driving the inspection piece 200 to move along the rotation axis of the rotating assembly 21 through the lifting mechanism 4, more of the inspection piece 200 is exposed within the field of view of the appearance inspection sensor 31. Combined with the rotation drive mechanism 5, which causes the inspection piece 200 to rotate relative to the rotating assembly 21, blind spots are eliminated, further improving the inspection accuracy of the appearance inspection device 100.

[0060] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the turret mechanism 2 also includes a drive shaft 41. The drive shaft 41 extends along the rotation axis of the rotating assembly 21, and one end of the drive shaft 41 in the length direction is used to clamp the detection element 200. When the drive shaft 41 clamps the detection element 200, the rotation drive mechanism 5 drives the detection element 200 to rotate by driving the drive shaft 41 to rotate.

[0061] Therefore, the clamping mechanism 412 at the lower end of the drive shaft 41 clamps the detection element 200, so that the rotary drive mechanism 5 drives the detection element 200 to rotate by driving the drive shaft 41, thereby realizing the rotation of the detection element 200 relative to the rotating assembly 21. At the same time, since the drive shaft 41 extends along the rotation axis of the rotating assembly 21, the rotation axis of the detection element 200 relative to the rotating assembly 21 coincides with the rotation axis of the rotating assembly 21, ensuring that the appearance inspection sensor 31 can move with the detection element 200, further improving the detection accuracy of the appearance inspection device 100.

[0062] In some embodiments of this utility model, such as Figure 13 As shown, the rotary drive mechanism 5 includes a second motor 51, a first rotating wheel, a second rotating wheel 52, and a conveyor belt 53. The first rotating wheel is connected to the output shaft of the second motor 51. The second rotating wheel 52 is spaced apart from the first rotating wheel and fixedly connected to the drive shaft 41. The conveyor belt 53 is wound around the first rotating wheel and the second rotating wheel 52.

[0063] Therefore, when the second motor 51 is energized, it outputs torque and drives the first rotating wheel to rotate. The conveyor belt 53 moves with the first rotating wheel and drives the second rotating wheel 52 to rotate. The second rotating wheel 52 drives the transmission shaft 41, which is fixedly connected to it, to rotate, and clamps the detection piece 200 through the transmission shaft 41, so that the detection piece 200 rotates relative to the rotating assembly 21. At the same time, the rotation drive mechanism 5 drives the transmission shaft 41 smoothly through the second motor 51, the first rotating wheel, the conveyor belt 53, and the second rotating wheel 52, thereby reducing the jitter and distortion of the appearance inspection image and improving the imaging clarity and detection accuracy.

[0064] The second rotating wheel 52 is fixedly connected to the transmission shaft 41 in the circumferential direction of the transmission shaft 41, and can move relative to it in the axial direction of the transmission shaft 41, so as to facilitate the up and down movement of the transmission shaft 41.

[0065] In a specific embodiment of this utility model, the appearance inspection device 100 further includes a lifting mechanism 4 and a rotation drive mechanism 5. The lifting mechanism 4 is disposed on the rotating assembly 21 and is used to drive the inspection piece 200 to move along the rotation axis of the rotating assembly 21. The rotation drive mechanism 5 is disposed on the rotating assembly 21 and is used to drive the inspection piece 200 to rotate relative to the rotating assembly 21.

[0066] Specifically, such as Figure 5 , Figure 7 , Figure 9 and Figure 11 As shown, the rotation axis of the rotating assembly 21 extends in the vertical direction. The rotating assembly 21 has a fixing groove 2111. The lower end of the detection piece 200 is adapted to be located in the fixing groove 2111. The lifting mechanism 4 includes a transmission shaft 41 and a second drive assembly 42. The transmission shaft 41 is movably disposed on the rotating assembly 21 in the vertical direction. The lower end of the transmission shaft 41 is provided with a clamping mechanism 412 for clamping the upper end of the detection piece 200. The second drive assembly 42 is disposed on the rotating assembly 21 and is used to drive the transmission shaft 41 to move up and down. The second drive assembly 42 includes a cam 421, which is mounted on the frame 1 and located above the rotating assembly 21. The outer peripheral wall of the cam 421 has a drive track 4211, which extends along the circumferential direction of the rotating assembly 21. The drive track 4211 includes at least one set of interconnected first track 4211a, second track 4211b and third track 4211c. Along the rotation direction of the rotating assembly 21, the first track 4211a is inclined upward, the second track 4211b is horizontally arranged, and the third track 4211c is inclined downward. The drive shaft 41 is provided with a mating part 411, which is movably disposed within the drive track 4211.

[0067] like Figure 12 and Figure 13 As shown, the rotary drive mechanism 5 includes a second motor 51, a first rotating wheel, a second rotating wheel 52, and a conveyor belt 53. The first rotating wheel is connected to the output shaft of the second motor 51. The second rotating wheel 52 is spaced apart from the first rotating wheel and fixedly connected to the transmission shaft 41. The conveyor belt 53 is wound around the first rotating wheel and the second rotating wheel 52. When the transmission shaft 41 clamps the detection piece 200, the rotary drive mechanism 5 drives the detection piece 200 to rotate relative to the rotating assembly 21 by driving the transmission shaft 41 to rotate.

[0068] Therefore, when the rotating assembly 21 rotates, the mating part 411 located on the drive shaft 41 will move along the drive track 4211. When the mating part 411 enters the upwardly inclined first track 4211a, the drive shaft 41 is driven to move upward. At this time, the clamping mechanism 412 at the lower end of the drive shaft 41 clamps the detection part 200 so that the detection part 200 rises together, thereby lifting the detection part 200 from the fixed groove 2111.

[0069] When the mating part 411 enters the horizontally set second track 4211b, the drive shaft 41 and the detection part 200 will move stably at the same height. At this time, the rotary drive mechanism 5 drives the drive shaft 41 to rotate through the second motor 51, the first rotating wheel, the conveyor belt 53, and the second rotating wheel 52, so that the detection part 200 rotates relative to the rotating assembly 21.

[0070] After the appearance inspection sensor 31 completes the inspection of the inspection piece 200, the second motor 51 stops working, and the mating part 411 enters the downwardly inclined third track 4211c along the second track 4211b. Under the action of the drive track 4211, the mating part 411 moves downward along the track so that the drive shaft 41 drives the inspection piece 200 down into the fixed groove 2111. Then, the clamping mechanism 412 at the lower end of the drive shaft 41 disengages from the inspection piece 200, and the inspection piece 200 is transferred to the subsequent station with the rotating assembly 21.

[0071] Furthermore, there are multiple bases 211, which are spaced apart along the circumferential direction of the rotating assembly 21. There are multiple drive shafts 41 corresponding to each base 211, multiple second drive assemblies 42 corresponding to each drive shaft 41, and multiple rotary drive mechanisms 5 corresponding to each drive shaft 41. Thus, after the detection piece 200 is matched with one of the drive shafts 41, the second drive assembly 42 and the rotary drive mechanism 5 connected to the same drive shaft 41 drive the detection piece 200 to move up and down and rotate relative to the rotating assembly 21, so that multiple detection pieces 200 can be placed on the rotating assembly 21, thereby improving the detection efficiency.

[0072] In some embodiments of this utility model, when there is only one appearance inspection sensor 31, the structure of the appearance inspection mechanism 3 is simple, reducing the cost of the appearance inspection device 100; or, as Figure 2 and Figure 3 As shown, there are multiple appearance inspection sensors 31, which are spaced apart along the circumferential direction of the rotating assembly 21, effectively improving the inspection efficiency of the appearance inspection device 100. Therefore, this arrangement allows for the installation of one or more appearance inspection sensors 31 as needed, enhancing the versatility of the appearance inspection device 100.

[0073] For example, such as Figure 2and Figure 3 As shown, there are two appearance detection sensors 31. Of course, the number of appearance detection sensors 31 in this application is not limited to this, and can also be one, three, four or more.

[0074] In some embodiments of this utility model, such as Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown, the turret mechanism 2 includes a third drive assembly 22, which is mounted on the frame 1 and is used to drive the rotating assembly 21 to rotate. Thus, by fixing the third drive assembly 22 to the frame 1, the third drive assembly 22 provides a stable circumferential driving force to the rotating assembly 21, thereby enabling the rotating assembly 21 to be rotatably mounted on the frame 1 and driving the detection element 200 on the rotating assembly 21 to rotate.

[0075] Furthermore, the third drive assembly 22 includes a third motor 221 and a third transmission assembly 222. The third transmission assembly 222 is connected to the output end of the third motor 221 and the rotating assembly 21 respectively, so that the driving force output by the third motor 221 is transmitted to the rotating assembly 21 through the third transmission assembly 222, thereby realizing the rotation of the rotating assembly 21.

[0076] In some embodiments of this utility model, such as Figure 6 As shown, the appearance inspection device 100 also includes a detection mechanism 6. The detection mechanism 6 is mounted on the rotating assembly 21 and is used to detect the rotational speed of the rotating assembly 21. Therefore, the detection mechanism 6 can be used to detect the rotational speed of the rotating assembly 21 and to synchronously control the appearance inspection sensor 31, further ensuring that the appearance inspection sensor 31 and the inspection piece 200 rotate synchronously, thus further improving the inspection accuracy.

[0077] Optionally, the detection mechanism 6 is an encoder used to detect the rotational speed of the rotating component 21 and provide this information to the controller so that the appearance inspection sensor 31 can move synchronously, thereby improving image consistency and appearance inspection data accuracy.

[0078] In some embodiments of this utility model, such as Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown, the appearance inspection device 100 also includes a conveying device 7 and an output device 8. The conveying device 7 is used to convey the inspection piece 200 to the rotating assembly 21, and the output device 8 is used to receive the inspection piece 200 output by the rotating assembly 21. The conveying device 7 and the output device 8 are located on opposite sides of the rotating assembly 21.

[0079] Therefore, since the conveying device 7 and the output device 8 are arranged on opposite sides of the rotating assembly 21, the test piece 200 can be conveyed to the rotating assembly 21 in a unidirectional path. After the test piece 200 of the rotating assembly 21 is tested, the output device 8 receives the test piece 200 output by the rotating assembly 21, which effectively avoids the intersection of upstream and downstream flows and interference between workstations, reduces waiting and alignment time, and maintains the continuity of the cycle.

[0080] Other components of the appearance inspection device 100 according to the embodiments of the present invention, such as the conveying device 7 and the output device 8, as well as their operation, are known to those skilled in the art and will not be described in detail here.
