Description

Technical Field

[0001] This application relates to the field of visual inspection technology, and more particularly to a visual inspection system. Background Technology

[0002] With the continuous advancement of industrial automation technology, machine vision-based methods for detecting product appearance defects have become increasingly mature, demonstrating significant effectiveness in improving inspection efficiency and accuracy. However, in existing conveyor belt or fixed-station inspection systems, the objects to be inspected typically move along a predetermined path or are fixed in a specific position. In such configurations, the vision inspection device is limited by its installation position and viewing angle, usually only acquiring image information from a single viewpoint (such as the top surface or a specific side). This makes it difficult to effectively capture defects on other surfaces of the object (especially areas with complex curvature or located behind the inspection device), creating blind spots and hindering the comprehensive detection of various types of appearance defects. This affects the overall inspection effect and reliability, increasing the risk of missed detections. Utility Model Content

Detailed Implementation

[0037] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0039] Reference Figures 1 to 6As shown, this application provides a visual inspection system, including a base 1, a rotating plate 2, a mounting component 3, a first driving mechanism 4, a second driving mechanism 5, and a visual inspection device. The rotating plate 2 is rotatably connected to the base 1 and can rotate relative to the base 1 about a first rotating axis. The mounting component 3 is rotatably connected to the rotating plate 2 and can rotate relative to the rotating plate 2 about a second rotating axis. The mounting component 3 has a fixed end for connecting the object to be measured. The first driving mechanism 4 is disposed between the base 1 and the rotating plate 2 and is drively connected to the rotating plate 2 to drive the rotating plate 2 to rotate about the first rotating axis. The second driving mechanism 5 is disposed between the mounting component 3 and the rotating plate 2 and is drively connected to the mounting component 3 to drive the mounting component 3 to rotate about the second rotating axis. The visual inspection device is disposed on one side of the base 1 and has a detection end facing the rotating plate 2. The first rotating axis and the second rotating axis are perpendicular to each other.

[0040] Specifically, the base 1 can be a frame structure welded from steel plates. The frame structure has a vertically arranged plate, and the rotating plate 2 is rotatably connected to the plate, so that the rotating plate 2 can rotate in the vertical direction.

[0041] The rotating plate 2 can be a rectangular plate structure. One end of the rotating plate 2 is rotatably connected to the base 1. Alternatively, both ends of the rotating plate 2 can be rotatably connected to the base 1. Bearings can be installed at the ends of the rotating plate 2, and the base 1 is connected to the bearings, so that the rotating plate 2 is rotatably connected to the base 1 through the bearings.

[0042] Mounting component 3 can be a column structure. Mounting component 3 is rotatably connected to rotating plate 2. The end of mounting component 3 away from rotating plate 2 is a fixed end. The fixed end can be equipped with a gripper or a suction cup so that the object to be tested can be stably connected to the fixed end. When mounting component 3 rotates relative to rotating plate 2, the object to be tested can rotate together with the mounting component.

[0043] The first drive mechanism 4 can be either a motor or a rotary cylinder. A gear is provided at the output end of the first drive mechanism 4, and a rack is provided on the outer side of the rotating shaft of the rotating plate 2. The gear and rack are meshed together. The first drive mechanism 4 drives the gear to rotate, and through the meshing of the gear and rack, drives the rotating plate 2 to rotate relative to the base 1. Alternatively, a roller can be provided at the output end of the first drive mechanism 4. The roller abuts against the outer wall of the rotating shaft of the rotating plate 2, and the first drive mechanism 4 drives the roller to rotate. The roller, through friction, drives the rotating shaft of the rotating plate 2 to rotate.

[0044] The second drive mechanism 5 can be either a motor or a rotary cylinder. The output end of the second drive mechanism 5 is equipped with a gear, and the outer side of the shaft rotatably connected to the rotating plate 2 of the mounting component 3 is equipped with a rack. The gear meshes with the rack. The first drive mechanism 4 drives the gear to rotate, and through the meshing of the gear and rack, drives the rotating plate 2 to rotate relative to the base 1. Alternatively, the output end of the second drive mechanism 5 can be equipped with a roller, which abuts against the outer wall of the rotating shaft of the rotating plate 2. The second drive mechanism 5 drives the roller to rotate, and the roller, through friction, drives the rotating shaft of the mounting component 3 to rotate.

[0045] The visual inspection device can include a camera and a controller. The controller is electrically connected to the camera. The camera is facing the rotating plate 2 to take pictures of the object to be tested on the mounting part 3 of the rotating plate 2. The camera outputs the captured images to the controller. The controller analyzes the images captured by the camera through software to analyze the appearance defects of the object to be tested.

[0046] The visual inspection device can be set on the top side of the rotating plate 2 or on the side of the rotating plate 2 in the horizontal direction, as long as the visual inspection device can capture the object to be tested connected to the mounting part 3 on the rotating plate 2.

[0047] The base 1 can be placed on a horizontal surface. The first axis of rotation between the rotating plate 2 and the base 1 can be set in the horizontal direction. The second axis of rotation between the mounting piece 3 and the rotating plate 2 is always perpendicular to the first axis of rotation. When the rotating plate 2 rotates around the first axis of rotation, the object under test adjusts its position as the rotating plate 2 rotates, so that the visual inspection device can capture images of different sides of the object under test along the circumference of the first axis of rotation, as well as the side of the object under test away from the rotating plate 2. When the mounting piece 3 rotates relative to the rotating plate 2, the object under test adjusts its position as the mounting piece 3 rotates, so that the visual inspection device can capture images of different sides of the object under test along the circumference of the second axis of rotation. In other words, the position and orientation of the object under test can be adjusted by the cooperation of the rotating plate 2 and the mounting piece 3, so that the visual inspection device can capture images of the object under test from multiple angles, accurately detect multiple sides of the object under test, and improve the accuracy of visual inspection.

[0048] In specific use, the visual inspection system provided in this application embodiment connects the object to be tested to a fixed end, the visual inspection device captures the rotating plate 2, the first driving mechanism 4 drives the rotating plate 2 to rotate relative to the base 1, and the second driving mechanism 5 drives the mounting part 3 to rotate relative to the rotating plate 2, so that different sides of the object to be tested face the detection end of the visual inspection device, so that the visual inspection device can analyze and detect the appearance defects of different sides of the object to be tested.

[0049] The vision inspection system provided in this application embodiment includes a rotating plate 2 rotatably mounted on a base 1, and a mounting component 3 rotatably mounted on the rotating plate 2. A first driving mechanism 4 drives the rotating plate 2 to rotate relative to the base 1 along a first rotating axis, and a second driving mechanism 5 drives the mounting component 3 to rotate relative to the rotating plate 2 and relative to a second rotating axis. The vision inspection device is disposed on one side of the base 1, with its detection end facing the rotating plate 2, so that the detection end can acquire image data of the object to be tested on the fixed end. The rotating plate 2 and the mounting component 3 form an orthogonal rotation axis system. The linkage between the rotating plate 2 and the mounting component 3 can adjust the angle and orientation of the object to be tested, so that different areas of the object to be tested can face the detection end. This allows the vision inspection device to analyze appearance defects on multiple sides of the object to be tested, reducing blind spots when the vision inspection device detects the object to be tested and improving the reliability of product appearance defect inspection through machine vision.

[0050] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the first drive mechanism 4 includes a servo motor 41 and a reducer 42. The servo motor 41 is fixed on the base 1. The input end of the reducer 42 is connected to the output end of the servo motor 41. The output end of the reducer 42 is connected to the rotating plate 2 for transmission, so that the servo motor 41 drives the rotating plate 2 to rotate around the first rotating shaft through the reducer 42.

[0051] With this configuration, the servo motor 41 drives the rotating plate 2 to rotate through the reducer 42. The reducer 42 has a low output speed and a high torque, which enables the rotating plate 2 to start rotating in time and slows down the rotation speed of the rotating plate 2, ensuring that the vision inspection device can accurately collect image information from multiple sides of the object under test.

[0052] Specifically, the servo motor 41 can be mounted on the base 1 by bolts or rivets. The output end of the servo motor 41 can be connected to the input end of the reducer 42 by a coupling. Alternatively, the output end of the servo motor 41 can be set as the driving wheel, and the output end of the reducer 42 can be set as the driven wheel. The driving wheel and the driven wheel are connected by a ring belt. The servo motor 41 drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate by the ring belt.

[0053] The reducer 42 can be selected as a planetary gear reducer or a harmonic reducer. The main function of the reducer is to reduce the high speed of the power source to the low speed required by the actuator through transmission components such as gears, while increasing the output torque and matching the mechanical characteristics of the power source and the load. The input end of the reducer 42 receives the power input from the servo motor 41, and then outputs it to the rotating plate 2 through the output end to drive the rotating plate 2 to rotate.

[0054] The servo motor 41 has a high output speed. When the output of the servo motor 41 is directly connected to the rotating plate 2 to drive the rotating plate 2, the rotating plate 2 is prone to rotating too fast and is difficult to position accurately. Furthermore, the rotating plate 2, the mounting part 3, and the object under test are relatively heavy, and the torque of the output of the servo motor 41 is relatively small, making it difficult to drive the rotating plate 2 to start rotating. The servo motor 41 drives the rotating plate 2 to rotate through the reducer 42. The reducer 42 has a low output speed and a high torque, which allows the rotating plate 2 to start rotating in time and slows down the rotation speed of the rotating plate 2, ensuring that the vision inspection device can accurately acquire image information from multiple sides of the object under test.

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the base 1 includes a base 11 and two upright plates 12 disposed opposite to each other on one side of the base 11; a rotating plate 2 is rotatably connected between the two upright plates 12; a servo motor 41 and a reducer 42 are both mounted on one upright plate 12, with the servo motor 41 disposed on the side of the reducer 42 closer to the base 11; the output end of the reducer 42 is provided with a flange plate 422, which is fixedly connected to the rotating plate 2; the output end of the servo motor 41 is provided with a drive wheel 411, and the input end of the reducer 42 is provided with a driven wheel 421; the drive wheel 411 and the driven wheel 421 are connected by a synchronous belt 43, so that the servo motor 41 drives the drive wheel 411 to rotate, the drive wheel 411 drives the driven wheel 421 to rotate via the synchronous belt 43, and the driven wheel 421 drives the flange plate 422 to rotate via the reducer 42.

[0056] With this configuration, the servo motor 41 and reducer 42 are mounted on a vertical plate 12, which allows the first drive mechanism 4 to make reasonable use of the space around the vertical plate 12, reduces the space occupied by the first drive mechanism 4 in the length direction of the base 11, and makes the structure of the vision inspection system compact.

[0057] Specifically, the base 11 can be a specific plate structure, with two upright plates 12 spaced apart along the length of the base 11 and a rotating plate 2 positioned between the two upright plates 12. The extension direction of the rotating plate 2 is consistent with the length direction of the base 11, and both ends of the rotating plate 2 are rotatably connected to the upright plates 12 through bearings.

[0058] The vertical plate 12 for setting the servo motor 41 and reducer 42 can be selected as an assembly plate. The assembly plate can be provided with a first through hole and a second through hole. The first through hole is on the side of the second through hole near the base 11. The servo motor 41 is set between the two vertical plates 12 and fixed to the assembly plate. The output end of the servo motor 41 extends through the first through hole to the side of the assembly plate away from the other vertical plate 12, so that the driving wheel 411 is on the side of the assembly plate away from the other vertical plate 12. The reducer 42 is set in the second through hole. The output end of the reducer 42 is between the two vertical plates 12, and the input end is on the side of the assembly plate away from the other vertical plate 12, so that the driven wheel 421 is on the side of the assembly plate away from the other vertical plate 12. The flange plate 422 is between the two vertical plates 12.

[0059] The synchronous belt 43 is an annular belt, which is fitted onto the driving pulley 411 and the driven pulley 421. When the synchronous belt 43 is taut, the rotation of the driving pulley 411 drives the synchronous belt 43 to rotate, which in turn drives the driven pulley 421 to rotate. Alternatively, the driving pulley 411 and the driven pulley 421 can abut against each other, allowing the synchronous belt 43 to rotate synchronously with them through friction. Alternatively, the synchronous belt 43 can have continuous toothed grooves, with both the driving pulley 411 and the driven pulley 421 being gears, and the synchronous belt 43 meshing with them.

[0060] The flange plate 422 described above is a planar plate. The flange plate 422 is fitted and connected to the rotating plate 2. When the flange plate 422 rotates, it can apply a force to the rotating plate 2 to determine the rotation of the rotating plate 2.

[0061] Reference Figure 1 , Figure 4 and Figure 6 As shown, in some embodiments, the mounting component 3 includes a main body 31 and an adsorption part 32. The main body 31 is rotatably connected to the rotating plate 2, and the adsorption part 32 is fixed to one end of the main body 31. The adsorption part 32 is used to communicate with an external air extraction device to form a negative pressure at the adsorption part 32 to adsorb and fix the object to be tested.

[0062] With this configuration, the adsorption unit 32 connects to the object to be tested by adsorption, avoiding wear on the surface of the object to be tested; after the adsorption unit 32 is attached to the surface of the object to be tested, the external air extraction device can be activated to connect the adsorption unit 32 to the object to be tested, improving the ease of operation of the mounting part 3 in connecting the object to be tested.

[0063] Specifically, the main body 31 can be a column structure, and the main body 31 can be rotatably mounted on the rotating plate 2 via a bearing. Alternatively, the rotating plate 2 can be provided with a through hole, and the main body 31 can be rotatably inserted into the through hole.

[0064] The adsorption part 32 can be a suction cup. One end of the suction cup is connected to an external air extraction device, and the other end is an open end. When the object to be tested is attached to the open end of the suction cup, the external air extraction device extracts air and creates a negative pressure environment inside the suction cup, so that the suction cup is tightly adsorbed onto the object to be tested.

[0065] Alternatively, the adsorption part 32 can be made of a block of flexible material, with an adsorption cavity formed inside the block. An opening communicating with the adsorption cavity is formed at the end of the block away from the main body 31. An installation port is provided on the block, and an external air extraction device communicates with the adsorption cavity through the installation port. After the block is attached to the surface of the object to be tested, the external air extraction device extracts air to create a negative pressure environment in the adsorption cavity, so that the block and the object to be tested are adsorbed and connected.

[0066] Reference Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the main body 31 includes a rotating seat 311 and a rotating shaft 312. The rotating plate 2 is provided with a mounting hole. The rotating seat 311 is mounted on one side of the rotating plate 2. The rotating shaft 312 is rotatably connected to the rotating seat 311. One end of the rotating shaft 312 extends to the side of the rotating seat 311 away from the rotating plate 2 and is fixedly mounted with the adsorption part 32. The other end passes through the mounting hole and is provided with a connector 33. The connector 33 is used for a sealed connection with an external air extraction device.

[0067] The rotating shaft 312 has an axial passage inside to form an air extraction channel. The adsorption part 32 and the connector 33 are both connected to the air extraction channel. The second drive mechanism 5 is connected to the rotating shaft 312 to drive the rotating shaft 312 to rotate around the second shaft.

[0068] With this configuration, the rotating seat 311 can be stably connected to the rotating plate 2. The rotating shaft 312 can both rotate the adsorption part 32 and form a pipe structure connecting the adsorption part 32 to the external air extraction device. This allows the external air extraction device to be connected to the rotating shaft 312 on the side of the rotating plate 2 away from the rotating seat 311, thus preventing the connection structure between the external air extraction device and the adsorption part 32 from obstructing the side of the object to be tested.

[0069] Specifically, the rotating seat 311 can be a block structure with a rotating hole on it. The rotating shaft 312 passes through the rotating hole. A bearing can be provided between the rotating shaft 312 and the inner wall of the rotating hole, or there can be a gap between the rotating shaft 312 and the inner wall of the rotating hole, so that the rotating shaft 312 can rotate on the rotating seat 311.

[0070] The rotating shaft 312 can be selected to include a first shaft section and a second shaft end. The diameter of the first shaft section is larger than the diameter of the second shaft section. The first shaft section is exposed on the surface of the rotating seat 311 and is connected to the adsorption part 32. The second shaft section is rotatably disposed within the rotating hole. The larger diameter of the first shaft section can withstand greater forces, thereby improving the stability of the adsorption part 32. The air extraction channel runs through both the first and second shaft sections. Alternatively, the rotating shaft 312 can be selected as a shaft with equal diameter at all points.

[0071] The aforementioned rotating plate 2 has a through mounting hole, allowing the end of the rotating shaft 312 away from the adsorption part 32 to be exposed on the side of the rotating plate 2 away from the rotating seat 311, enabling the external air extraction device to connect to the connector 33. The output end of the second drive mechanism 5 can optionally be equipped with a gear, or a rack can be provided on the outer wall of the rotating shaft 312. The output end of the second drive mechanism 5 meshes with the rotating shaft 312, allowing the second drive mechanism 5 to drive the rotating shaft 312 to rotate. Alternatively, the output end of the second drive mechanism 5 can be equipped with a wheel, connected to the rotating shaft 312 via an annular belt. When the wheel rotates, it drives the rotating shaft 312 to rotate via the annular belt.

[0072] The rotating shaft 312 is hollow to form an air extraction channel. The connector 33 can be a pagoda-shaped structure, allowing the hose to be fitted onto the connector 33 and sealed to it. The external air extraction device is connected to the air extraction channel through the hose. After the external air extraction device is activated, it creates a negative pressure at the adsorption section 32 through the air extraction channel to adsorb and connect the object to be tested.

[0073] Reference Figure 1 , Figure 4 and Figure 6 As shown, in some embodiments, the adsorption unit 32 includes a mounting plate 321 and a plurality of suction cups 322. The mounting plate 321 is fixed to the end of the rotating shaft 312, and the plurality of suction cups 322 are disposed on the side of the mounting plate 321 away from the rotating shaft 312, and the suction cups 322 are connected to the air extraction channel.

[0074] With this configuration, the mounting plate 321 serves as the structural basis for mounting multiple suction cups 322. When adsorbing and connecting the object to be tested, the mounting plate 321 can first abut against the surface of the object to be tested to form a positioning, and then the suction cups 322 can adsorb and connect the object to be tested. When the mounting part 3 rotates, the mounting plate 321 remains in contact with the object to be tested, increasing the contact area between the object to be tested and the adsorption part 32, and improving the stability when the object to be tested is connected to the adsorption part 32.

[0075] Specifically, the mounting plate 321 is a plate structure. Optionally, the mounting plate 321 can have multiple mounting holes that communicate with the air extraction channel. The suction cup 322 is positioned within these mounting holes and is sealed to the inner wall of the mounting hole. Alternatively, the mounting plate 321 can include a base plate and an abutment plate. The base plate is fixedly connected to the rotating shaft 312, and the abutment plate is fixedly connected to the side of the base plate away from the rotating shaft 312. The suction cup 322 is positioned on the abutment plate, and the abutment plate abuts against the object to be tested, allowing the suction cup 322 to adhere to and connect with the object.

[0076] The suction cup 322 has a conical structure. One end of the suction cup 322 has an opening, and the other end has an air extraction port. The opening of the suction cup 322 is located on the side away from the rotating shaft 312. After the opening of the suction cup 322 is attached to the object to be tested, the external air extraction device extracts air, and the gas inside the suction cup 322 is discharged through the air extraction port and the air extraction channel to create a negative pressure environment between the suction cup 322 and the object to be tested, so that the suction cup 322 is attached to the surface of the object to be tested.

[0077] Reference Figure 1 , Figure 4 and Figure 6 As shown, in some embodiments, there are multiple mounting components 3, and each rotating seat 311 is rotatably connected to a driven coupling 34, which is connected to the rotating shaft 312 on the rotating seat 311. The second drive mechanism 5 includes a drive motor 51 and a transmission belt group 52. The output end of the drive motor 51 is connected to multiple driven couplings 34 through the transmission belt group 52, so that the drive motor 51 drives multiple driven couplings 34 to rotate synchronously.

[0078] With this configuration, multiple mounting components 3 can simultaneously place multiple objects to be tested on the rotating plate 2. Multiple driven couplings 34 are connected to the drive motor 51 via a transmission belt assembly 52, enabling multiple mounting components 3 to rotate synchronously. This means that multiple objects to be tested can rotate synchronously around the first axis with the rotating plate 2, and multiple objects to be tested can rotate synchronously around the second axis. This allows the visual inspection device to simultaneously detect and analyze the appearance defects of multiple objects to be tested, improving the detection and analysis efficiency of the visual inspection system.

[0079] Specifically, the number of mounting parts 3 can be six, eight, or other quantities; multiple mounting parts 3 can be spaced apart along the length of the rotating plate 2. Multiple rotating seats 311 can be all located on one side of the rotating plate 2, and driven couplings 34 can be located on the side of the rotating plate 2 where the rotating seats 311 are located. The output end of the drive motor 51 is located on the side of the rotating plate 2 where the rotating seats 311 are located, so that the output end of the drive motor 51 is connected to the multiple driven couplings 34 via a transmission belt assembly 52. ​​Alternatively, the rotating hole on the rotating plate 2 can be larger or have mounting holes corresponding to the rotating seats 311, so that the driven couplings 34 are located on the side of the rotating plate 2 away from the rotating seats 311 through the rotating hole or mounting hole, and the output end of the drive motor 51 is on the side of the rotating plate 2 opposite to the rotating seats 311, with the output end of the drive motor 51 connected to the multiple driven couplings 34 via a transmission belt assembly 52.

[0080] The driven coupling 34 may optionally be equipped with a rack, and the rotating shaft 312 may be equipped with a toothed groove. The driven coupling 34 and the rotating shaft 312 are meshed and connected, so that the driven coupling 34 can drive the rotating shaft 312 to rotate. Alternatively, an annular belt may be used to be fitted around the driven coupling 34 and the rotating shaft 312. The annular belt is in a taut state, so that the driven coupling 34 can drive the rotating shaft 312 to rotate.

[0081] The aforementioned transmission belt assembly 52 may include an annular belt body, which is sleeved on multiple driven pulleys 34 and the output end of the drive motor 51. The annular belt body is in a tensioned state and is in contact with each driven pulley 34. When the output end of the drive motor 51 drives the annular belt body to rotate, the annular belt body can drive the multiple driven pulleys 34 to rotate.

[0082] Alternatively, the transmission belt assembly 52 can include multiple belt bodies, with one belt body fitted between every two adjacent driven pulleys 34. The output end of the drive motor 51 is connected to any one of the driven pulleys 34 via the belt body. When the output end of the drive motor 51 rotates, it causes one driven pulley 34 to rotate through the belt body, and the multiple belt bodies cause the remaining driven pulleys 34 to rotate synchronously.

[0083] Reference Figure 1 and Figure 4 As shown, in some embodiments, the transmission belt assembly 52 includes multiple sub-belt bodies, and multiple mounting members 3 are arranged at intervals along the length direction of the rotating plate 2. Along the length direction of the rotating plate 2, two adjacent driven couplings 34 are connected by a sub-belt body. The drive motor 51 is connected to the adjacent driven couplings 34 by a sub-belt body, so that the drive motor 51 drives multiple driven couplings 34 to rotate synchronously through multiple sub-belt bodies.

[0084] With this configuration, multiple driven pulleys 34 are connected by multiple sub-belts in a segmented transmission manner, so that each driven pulley 34 can fit tightly with the sub-belt. The multiple sub-belts can stably transmit the driving force of the multiple driven pulleys 34 to the drive motor 51, ensuring that the multiple driven pulleys 34 can rotate stably and synchronously.

[0085] Specifically, a sub-belt is fitted around the outer side of each pair of adjacent driven pulleys 34. The sub-belt is in a tensioned state, allowing the adjacent driven pulleys 34 to rotate synchronously. Alternatively, the drive motor 51 can be positioned on one side of the multiple driven pulleys 34, with the drive motor 51 connected to the driven pulley 34 closest to it via the sub-belt. Each pair of adjacent driven pulleys 34 is also connected via the sub-belt. Alternatively, the drive motor 51 can be positioned between the multiple driven pulleys 34, meaning that driven pulleys 34 are located on both sides of the rotating plate 2 along its length. The drive motor 51 is connected to each adjacent pair of driven pulleys 34 via transmission. Each pair of adjacent driven pulleys 34 on both sides of the drive motor 51 is connected via transmission.

[0086] Reference Figure 1 and Figure 4 As shown, in some embodiments, the rotating plate 2 is provided with a plurality of tensioning wheel sets 53, and at least one tensioning wheel set 53 is provided at each sub-belt body, and the tensioning wheel set 53 abuts against the sub-belt body to adjust and maintain the tension of the sub-belt body.

[0087] With this configuration, multiple tensioning pulley sets 53 ensure that each sub-belt is in a tensioned state, ensuring that the sub-belt can stably transmit force and preventing the sub-belt from slipping and causing asynchronous rotation of multiple rotating shafts 312.

[0088] Specifically, the rotating plate 2 may have six mounting parts 3, thus providing at least six sub-belt bodies. The rotating plate 2 is equipped with six tensioning wheel sets 53, with one tensioning wheel set 53 corresponding to each sub-belt body. The tensioning wheel sets 53 abut against the sub-belt body, causing the sub-belt body to undergo elastic deformation. The elastic force of the sub-belt body itself ensures that the sub-belt body is in close contact with the driven coupling 34, ensuring that the sub-belt body can transmit force between the two driven couplings 34.

[0089] The tensioning pulley assembly 53 has a shaft and a pulley. The shaft is mounted on the rotating plate 2 and is located close to the sub-belt body. The pulley is rotatably connected to the shaft and abuts against the sub-belt body. When the sub-belt body moves, it rotates on the shaft. Each sub-belt body can be equipped with one tensioning pulley assembly, or two tensioning pulley assemblies can be selected for each sub-belt body. The greater the deformation of the sub-belt body, the higher the tension of the sub-belt body, and the greater the contact force between the sub-belt body and the driven coupling 34.

[0090] Reference Figure 1 and Figure 2 As shown, in some embodiments, the visual inspection system further includes an angle detection device 6, which includes a sensor 61 and a sensing plate 62. The sensor 61 is provided on the base 1, and the sensing plate 62 is provided on the rotating plate 2. The sensor 61 can detect the position of the sensing plate 62 to determine the rotation angle of the rotating plate 2 around the first rotating axis.

[0091] With this setup, the angle detection device 6 monitors the rotation angle of the rotating plate 2 in real time, ensuring that the rotating plate 2 rotates to the correct position each time.

[0092] Specifically, sensor 61 can be a photoelectric sensor or a laser sensor, and sensing plate 62 is a plate body set on rotating plate 2. It can be selected that there is a through hole on vertical plate 12. Sensor 61 is set on the side of vertical plate 12 facing away from the other vertical plate 12. Sensing plate 62 extends through the through hole to sensor 61. When rotating plate 2 rotates, it drives sensing plate 62 to rotate. Sensor 61 detects the position of sensing plate 62 to determine the rotation angle of rotating plate 2.

[0093] In some embodiments, the visual inspection system further includes a controller electrically connected to the visual inspection device, which can receive data collected by the visual inspection device.

[0094] The controller can be electrically connected to the angle detection device 6. The rotating plate 2 can be selected to have several set positions. For example, the initial position is when the rotating plate 2 is parallel to the base 11. The first detection position is when the rotating plate 2 rotates 90° clockwise from the initial position. The second detection position is when the rotating plate 2 rotates 90° counterclockwise from the initial position. The angle detection device 6 detects the rotation angle of the rotating plate 2, so it can monitor whether the rotating plate 2 is in position when switching between the initial position, the first detection position and the second detection position.

[0095] In specific use, the visual inspection system provided in this application embodiment places the object to be tested on the mounting plate 321 of the adsorption part 32. An external air extraction device extracts air, causing multiple suction cups 322 to adsorb and connect to the surface of the object to be tested, so that the object to be tested is adsorbed onto the adsorption part 32. Each of the multiple mounting parts 3 has one object to be tested adsorbed and connected to its adsorption part 32.

[0096] The detection end of the visual inspection device is set towards the rotating plate 2, so that the visual inspection device can capture multiple objects to be tested; the output end of the servo motor 41 drives the drive wheel 411 to rotate, the drive wheel 411 drives the driven wheel 421 to rotate through the synchronous belt 43, the driven wheel 421 drives the flange plate 422 to rotate through the reducer 42, and the flange plate 422 drives the rotating plate 2 to rotate, so that different sides of the objects to be tested face the detection end.

[0097] The drive motor 51 drives multiple driven pulleys 34 to rotate synchronously through the transmission belt group 52, so that the rotating shaft 312 rotates synchronously. Multiple objects to be tested rotate synchronously with the rotating shaft 312 so that different sides of the objects to be tested face the detection end. The controller receives image information collected by the vision inspection device to analyze whether the objects to be tested have appearance defects.
