Description

Technical Field

[0001] This application belongs to the field of visual inspection technology, specifically relating to a multi-station inspection device. Background Technology

[0002] With technological advancements and improved living standards, smart devices have gradually become necessities in people's lives. Smartwatches, as one type of smart device, offer communication, health monitoring, and IoT-based information interaction functions, and have been widely adopted. While pursuing superior performance, people are also placing high demands on the aesthetics of smartwatches.

[0003] The back cover of a smartwatch is typically made of glass with a rounded surface. It features several circular holes arranged around its circumference, serving as light-passing holes for sensors such as heart rate sensors. The watch needs to be worn close to the skin of the arm. To ensure watch quality, strict control must be exercised over dimensional tolerances, including deviations in the size and hole positions of the back cover, as well as surface defects such as foreign objects, unevenness, scratches, dents, ink defects, dirt, and discoloration. This ensures the assembly precision and strength of the back cover, as well as its aesthetic appeal and integrity, preventing defective products. Therefore, the back cover undergoes comprehensive performance testing before leaving the factory.

[0004] The back cover is small and thin, and the testing system is very close to the back cover of the watch being tested when it is working, which puts a lot of space requirements on the equipment; in addition, small products require high production capacity, so the equipment's cycle time is relatively fast.

[0005] However, the existing machine vision inspection equipment for glass covers mainly uses the flow channel inspection method, which cannot meet the cycle time required for inspecting watch back covers, resulting in low inspection efficiency and high operating costs. Summary of the Invention

[0006] Therefore, the technical problem to be solved by this application is to provide a multi-station inspection device, which, through the layout of dual inspection channels, sets eight inspection stations in each inspection channel, so that the multi-station inspection device can complete the inspection of sixteen watch back covers in a single operation, thereby improving the inspection efficiency of watch back covers.

[0007] To address the aforementioned issues, this application provides a multi-station inspection device, comprising a frame and at least two inspection channels arranged opposite to each other on the frame along a first direction. Each inspection channel includes a feeding mechanism, a first positioning mechanism, and a second positioning mechanism. The first positioning mechanism is located on the second direction side of the feeding mechanism, and the second positioning mechanism is located on the second direction side of the first positioning mechanism. The feeding mechanism is used to transport the object to be inspected to the receiving station in the second direction. The first positioning mechanism and the second positioning mechanism are respectively provided with material handling mechanisms on the side away from the frame. The material handling mechanisms are used to transport the object to be inspected from the receiving station to the receiving station. The first positioning mechanism and the second positioning mechanism can drive the object to be inspected, which has been transported to the receiving station, to move from the receiving station to the inspection station.

[0008] The first positioning mechanism is provided in at least four places, the second positioning mechanism is provided in at least four places, and the material handling mechanism is also used to drive the object to be tested to move between two adjacent receiving stations.

[0009] Beneficial effects

[0010] The multi-station inspection equipment provided in the embodiments of the present invention, by setting two inspection channels and respectively setting four first positioning mechanisms and four second positioning mechanisms in the two inspection channels, enables the multi-station inspection equipment to complete the inspection of sixteen items in a single operation, which can effectively reduce the inspection time of a single item and improve the inspection efficiency, thereby effectively saving production costs and having good economic benefits; at the same time, the feeding mechanism, material handling mechanism, first positioning mechanism, material transfer mechanism, second positioning mechanism, lifting and rotating mechanism and discharge mechanism adopt an integrated design, which can optimize the transfer process of the items to be inspected, making the equipment structure compact, and improving the degree of automation of the equipment.

[0025] See also Figures 1 to 14 As shown, according to an embodiment of this application, a multi-station testing device is provided, including a frame 100 and at least two testing channels arranged opposite to each other on the frame 100 along a first direction. The testing channels include a feeding mechanism 200, a first positioning mechanism 300, and a second positioning mechanism 400. The first positioning mechanism 300 is disposed on the second direction side of the feeding mechanism 200, and the second positioning mechanism 400 is disposed on the second direction side of the first positioning mechanism 300. The feeding mechanism 200 is used to transport the object to be tested to the receiving station in the second direction. The first positioning mechanism 300 and the second positioning mechanism 400 are respectively provided with a material handling mechanism 500 on the side away from the frame 100. The material handling mechanism 500 is used to transport the object to be tested from the receiving station to the receiving station. The first positioning mechanism 300 and the second positioning mechanism 400 can drive the object to be tested transported to the receiving station to move from the receiving station to the testing station.

[0026] Among them, at least four first positioning mechanisms 300 and at least four second positioning mechanisms 400 are provided, and the material handling mechanism 500 is also used to move the object to be tested between two adjacent receiving stations.

[0027] The multi-station inspection equipment provided in the embodiments of the present invention, by setting two inspection channels and respectively setting four first positioning mechanisms 300 and four second positioning mechanisms 400 in the two inspection channels, enables the multi-station inspection equipment to complete the inspection of sixteen items in a single operation, which can effectively reduce the inspection time of a single item and improve the inspection efficiency, thereby effectively saving production costs and having good economic benefits; at the same time, by setting a material handling mechanism 500 to transfer the items to be inspected, the transfer process of the items to be inspected is optimized, making the multi-station inspection equipment compact and having a high degree of automation.

[0028] The object to be tested can be electronic components, automotive parts, mobile phone parts, watch parts, screws and nuts, composite material components such as plastics, ceramics, and buttons, magnesium, aluminum and their alloys, etc., and this invention does not impose further limitations. In this embodiment, the object to be tested is a watch part.

[0029] Specifically, the object to be inspected is a watch cover, and the multi-station inspection equipment is used to inspect the assembly accuracy and appearance defects of the watch cover.

[0030] The multi-station testing equipment includes a frame 100. In one embodiment, the frame 100 is an integral unit; in another embodiment, the frame 100 is a split unit.

[0031] Specifically, in this embodiment, the frame 100 is a split type, comprising a first frame 101 and a second frame 102. The first frame 101 and the second frame 102 are arranged opposite to each other in a second direction. The first frame 101 and the second frame 102 are connected, and the connection method can be snap-fit ​​or bolted connection, etc., which are not further limited in this invention. By setting the frame 100 to a split type, the portability of the multi-station testing equipment is improved, thereby improving work efficiency.

[0032] The frame 100 is used to support the detection channel, and the second direction can be the direction of travel of the object to be detected in the detection channel.

[0033] Specifically, two, three, or four detection channels can be set. It is understood that multiple detection channels can simultaneously detect the object to be tested; that is, the more detection channels there are, the higher the detection efficiency. However, setting more than two detection channels will increase the production cost of the multi-station detection equipment, hindering its widespread use. In this embodiment, two detection channels are set, arranged back-to-back, which can balance the production cost of the multi-station detection equipment with the improvement of the detection efficiency of the object to be tested.

[0034] The two detection channels are arranged opposite each other, that is, the two detection channels are arranged opposite each other in the first direction.

[0035] The first direction is perpendicular to the direction of travel of the object to be tested in the horizontal plane, and the first direction can be the direction from the receiving station to the testing station.

[0036] The detection channel includes a feeding mechanism 200, which can be a belt conveyor 2033, a screw conveyor, or a vibrating conveyor, etc., and the present invention does not impose further limitations. The feeding mechanism 200 is mounted on the first frame 101 and is used to transport the upstream object to be tested into the detection channel for testing.

[0037] Specifically, the second end of the feeding mechanism 200 has a material-retrieving station. After the object to be tested is placed on the feeding mechanism 200, the feeding mechanism 200 can move the object to be tested to the material-retrieving station, which facilitates the subsequent transfer of the object to be tested.

[0038] The detection channel also includes a first positioning mechanism 300, which is located on the second direction side of the feeding mechanism 200. The first positioning mechanism 300 is used to accurately position the object to be tested in order to improve the accuracy of the detection results.

[0039] Specifically, four, five, or six first positioning mechanisms 300 may be provided. In this embodiment, four first positioning mechanisms 300 are provided, and the four first positioning mechanisms 300 are arranged on the first frame 101 along the second direction. The four first positioning mechanisms 300 are located in the same plane, and the plane in which the four first positioning mechanisms 300 are located is parallel to the plane in which the feeding mechanism 200 is located.

[0040] It is understandable that one first positioning mechanism 300 represents one workstation. That is, by setting four first positioning mechanisms 300, there are four workstations in the detection flow channel, which can detect four objects to be detected at the same time, thus improving detection efficiency.

[0041] The detection channel also includes a second positioning mechanism 400, which is located on the second direction side of the first positioning mechanism 300. The second positioning mechanism 400 is also used to accurately position the object to be detected in order to improve the accuracy of the detection results.

[0042] Specifically, four, five, or six second positioning mechanisms 400 can be provided. In this embodiment, four second positioning mechanisms 400 are provided, and the four second positioning mechanisms 400 are mounted on the second frame 102 and arranged along a second direction on the second frame 102. The four second positioning mechanisms 400 are located in the same plane, and the plane containing the four second positioning mechanisms 400 is coplanar with the plane containing the four first positioning mechanisms 300.

[0043] It is understandable that one second positioning mechanism 400 also represents one workstation. That is, by setting four second positioning mechanisms 400, there are four workstations on the second direction side of the four second positioning mechanisms 400 in the detection channel. In other words, there are a total of eight workstations in the detection channel, which can detect eight objects to be detected at the same time, further improving the detection efficiency.

[0044] In this application, the multi-station inspection equipment adopts a dual-inspection flow channel layout, with eight stations in each inspection flow channel, so that the multi-station inspection equipment can complete the inspection of sixteen watch back covers in a single operation, thereby improving the inspection efficiency of watch back covers.

[0045] The detection channel also includes a material handling mechanism 500, which can be a robotic arm or the like, as long as it can transfer the object to be detected. This invention does not impose any further limitations.

[0046] Among them, two material handling mechanisms 500 are provided. One material handling mechanism 500 is located on the first frame 101 on the side of the four first positioning mechanisms 300 away from the first frame 101, and the other material handling mechanism 500 is located on the second frame 102 on the side of the four second positioning mechanisms 400 away from the second frame 102.

[0047] The first positioning mechanism 300 and the second positioning mechanism 400 each have a receiving station and a testing station. The material handling mechanism 500 can transfer the object to be tested from the receiving station to the receiving station on the first positioning mechanism 300 and the second positioning mechanism 400. The first positioning mechanism 300 and the second positioning mechanism 400 are used to move the object to be tested from the receiving station to the testing station.

[0048] The system includes four first positioning mechanisms 300 and four second positioning mechanisms 400, resulting in eight receiving stations. The material handling mechanism 500 can also transfer the material to be inspected from one receiving station to another.

[0049] Specifically, in this application, the object to be tested is fed from the feeding mechanism 200, moved to the receiving station via the feeding mechanism 200, and then transferred by the material handling mechanism 500 to the receiving station of the first positioning mechanism 300. After being positioned by the first positioning mechanism 300, the object to be tested is moved to the testing station, and after testing, it moves back to the receiving station. Then, the material handling mechanism 500 transfers the object to be tested to the next first positioning mechanism 300, and the above operation is repeated to complete the four tests one by one. The first positioning mechanism 300 performs the inspection, and then the material handling mechanism 500 transfers the object to be inspected from the receiving station of the last first positioning mechanism 300 to the receiving station of the first second positioning mechanism 400. After being positioned by the second positioning mechanism 400, the object to be inspected moves to the inspection station, completes the inspection, and then moves back to the receiving station. Then the material handling mechanism 500 transfers the object to be inspected to the next second positioning mechanism 400. The above operation is repeated to complete the inspection of the four second positioning mechanisms 400 one by one.

[0050] The receiving station is positioned opposite the material-to-be-picked station in the second direction, and the inspection station is positioned opposite the vision inspection mechanism in the vertical direction.

[0051] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 2 and Figure 3 As shown, the feeding mechanism 200 includes a drive motor 201, a belt drive assembly 202, and a belt conveyor assembly 203. The object to be tested is placed on the belt conveyor assembly 203. The first end of the belt drive assembly 202 is connected to the belt conveyor assembly 203, and the second end is connected to the drive motor 201. The drive motor 201 is used to drive the belt drive assembly 202 to move, so as to move the object to be tested through the belt conveyor assembly 203.

[0052] By setting the belt drive assembly 202 so that the torque output by the drive motor 201 can be stably transmitted to the belt conveyor assembly 203, the stability of the object to be tested moving on the belt conveyor assembly 203 can be improved.

[0053] The drive end of the drive motor 201 is connected to the input end of the belt drive assembly 202, and the output end of the belt drive assembly 202 is connected to the input end of the belt conveyor assembly 203. The drive motor 201 can drive the object to be tested to move toward the material pick-up station in the second direction through the belt drive assembly 202 and the belt conveyor assembly 203.

[0054] Specifically, the drive motor 201 can be a stepper motor, etc. The drive end of the drive motor 201 is connected to the belt drive assembly 202 and is used to drive the belt drive assembly 202 to move. The drive end of the drive motor 201 can be understood as the motor shaft of the motor, specifically the motor shaft of a stepper motor. It is understood that the belt drive assembly 202 is a reduction mechanism, which can reduce speed and transmit torque. In this embodiment, the belt drive assembly 202 can be a gear reduction mechanism, a worm gear reduction mechanism, or a belt 2033 pulley reduction mechanism, etc. When the drive motor 201 is a stepper motor, because the stepper motor rotates at a relatively high speed, the reduction effect of the belt drive assembly 202 can reduce the step angle pause time of the stepper motor, thereby reducing the jamming during the movement of the belt conveyor assembly 203, making the moving speed of the object to be detected closer to a uniform speed, and improving the stability of the object's movement. At the same time, it also reduces the running resistance of the drive motor 201 and increases its service life.

[0055] The belt drive assembly 202 includes a drive pulley 2021, a driven pulley 2022, and a timing belt 2023. It is understood that the timing belt 2023 includes a belt 2033 with a relatively smooth inner wall and a timing toothed belt with meshing teeth on its inner wall. The drive pulley 2021 and the driven pulley 2022 include a belt 2033 pulley with a relatively smooth outer peripheral wall and a timing toothed pulley with meshing teeth on its outer peripheral wall. In this embodiment, the timing belt 2023 is a timing toothed belt, and the drive pulley 2021 and the driven pulley 2022 are timing toothed pulleys. The timing belt 2023 is meshed with the drive pulley 2021 and the driven pulley 2022, respectively.

[0056] The driving wheel 2021 is coaxially mounted with the driving end of the drive motor 201. The driving end of the drive motor 201 drives the driving wheel 2021 to rotate around its axis. A synchronous belt 2023, simultaneously wound around the driving wheel 2021 and the driven wheel 2022, drives the driven wheel 2022 to rotate around its axis. Specifically, the drive motor 201 is a stepper motor, and the driving wheel 2021 is coaxially mounted on the output shaft of the stepper motor.

[0057] The belt conveyor assembly 203 includes a first belt roller 2031, a second belt roller 2032, and a belt 2033. The object to be tested is placed on the belt 2033, and the belt 2033 is connected to the first belt roller 2031 and the second belt roller 2032 respectively.

[0058] Specifically, the first belt roller 2031 and the driven wheel 2022 are coaxially arranged. The driven wheel 2022 is sleeved on the first belt roller 2031. The rotation of the driven wheel 2022 can drive the first belt roller 2031 to rotate around the axis of the first belt roller 2031. At the same time, the belt 2033, which is wrapped around the second belt roller 2032 on the first belt roller 2031, drives the second belt roller 2032 to rotate around the axis of the second belt roller 2032. At this time, the belt 2033 can move, that is, the object to be detected can move.

[0059] It is understood that the belt conveyor assembly 203 may also include a third belt roller, which is disposed between the first belt roller 2031 and the second belt roller 2032, and the belt 2033 is also connected to the third belt roller. By providing the third belt roller, the belt 2033 can be tensioned when it is long, thereby improving the stability of the movement of the object to be tested.

[0060] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 2 and Figure 3 As shown, the feeding mechanism 200 also includes a bearing seat 204, and the belt conveyor assembly 203 is disposed on the bearing seat 204. The bearing seat 204 includes a first surface 2041 and a second surface 2042 facing away from each other, and a first through hole 2043 is provided on the bearing seat 204 to penetrate the first surface 2041 and the second surface 2042.

[0061] The first surface 2041 of the bearing housing 204 is provided with a drive motor 201, and the second surface 2042 of the bearing housing 204 is provided with a belt drive assembly 202. The drive end of the drive motor 201 passes through the first through hole 2043 and is connected to the belt drive assembly 202.

[0062] By setting the bearing housing 204, a stable mounting position is provided for the drive motor 201, the belt drive assembly 202, and the belt conveyor assembly 203, and the drive motor 201 can stably drive the object to be tested to move through the belt drive assembly 202 and the belt conveyor assembly 203.

[0063] It is understandable that the bearing housing 204 can be U-shaped, and the bearing housing 204 has a receiving cavity. The first surface 2041 can be the inner wall surface of the bearing housing 204, and the second surface 2042 can be the outer wall surface of the bearing housing 204.

[0064] The first through hole 2043 is opened along the first direction.

[0065] The drive end of the drive motor 201 extends in the opposite direction of the first direction and passes through the first through hole 2043, and is fixedly connected to the drive wheel 2021. The drive wheel 2021 and the driven wheel 2022 are rotatably mounted on the second surface 2042 of the bearing seat 204.

[0066] The belt conveyor assembly 203 is located at the top opening of the bearing housing 204.

[0067] Specifically, the feeding mechanism 200 also includes flange bearings, and the first belt roller 2031 and the second belt roller 2032 are arranged across the two ends of the bearing housing 204 via the flange bearings.

[0068] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 2 As shown, the feeding mechanism 200 also includes two guide baffles 205 and two guide edges 206 that are disposed opposite to each other on the bearing seat 204 along the first direction. The two guide edges 206 are disposed on the second direction side of the two guide baffles 205, and the distance between the two guide edges 206 gradually decreases in the second direction.

[0069] By setting guide baffle 205 and guide edge 206, the object to be inspected can be limited in the first direction during the movement of the object to be inspected, thereby avoiding the offset between the object to be inspected and the material picking station in the first direction.

[0070] The guide baffle 205 can be a rectangular metal plate, etc. The guide baffle 205 is set on the top of the bearing seat 204 and extends along the second direction, and is used to provide preliminary guidance for the object to be tested.

[0071] Specifically, in this embodiment, two guide baffles 205 are provided, and the two guide baffles 205 are disposed opposite to each other on the bearing seat 204 along the first direction. One guide baffle 205 is disposed on the first direction side of the belt 2033 and is used to limit the object to be tested in the first direction; the other guide baffle 205 is disposed on the opposite direction side of the first direction of the belt 2033 and is used to limit the object to be tested in the opposite direction of the first direction.

[0072] The guide edge 206 can be a trapezoidal metal plate, etc. The guide edge 206 is set on the side of the guide baffle 205 near the material to be picked up. The guide edge 206 is used to accurately guide the object to be inspected.

[0073] In this embodiment, two guide edges 206 are provided, and the two guide edges 206 are disposed opposite to each other on the bearing seat 204 along the first direction. One guide edge 206 is disposed on the first direction side of the belt 2033 and is used to limit the object to be tested in the first direction; the other guide edge 206 is disposed on the opposite direction side of the first direction of the belt 2033 and is used to limit the object to be tested in the opposite direction of the first direction.

[0074] Specifically, the upper bases of the two trapezoidal guide edges 206 are positioned close to the guide baffle 205, and the lower bases of the two trapezoidal guide edges 206 are positioned close to the material-to-be-picked station. This means the distance between the two trapezoidal guide edges 206 gradually decreases in the second direction. In other words, the distance between the two trapezoidal guide edges 206 gradually decreases in the direction of movement of the object to be inspected, thereby reducing the swaying space of the object to be inspected in the first direction and preventing offset between the object to be inspected and the material-to-be-picked station in the first direction.

[0075] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 2 and Figure 3 As shown, the feeding mechanism 200 also includes an adjusting cylinder 207 and a pusher rod 208. The adjusting cylinder 207 is disposed on the first surface 2041 of the bearing seat 204. The pusher rod 208 is connected to the adjusting cylinder 207. The adjusting cylinder 207 is used to drive the pusher rod 208 toward the direction of approaching or away from the material to be picked up and fix it in a preset position. The end of the pusher rod 208 away from the adjusting cylinder 207 is higher than the belt conveyor assembly 203. The pusher rod 208 is used to limit the object to be inspected in the opposite direction of the second direction.

[0076] By setting the push rod 208, the object to be inspected can be limited in the second direction, thereby avoiding the offset between the object to be inspected and the material to be picked up in the second direction.

[0077] The push rod 208 can be a cylindrical metal rod, etc. The push rod 208 is set on the second direction side of the material to be picked up and extends in a vertically upward direction to stop the object to be inspected, thereby preventing the material from falling and so that the object to be inspected can be limited at the material to be picked up.

[0078] Two push rods 208 can be provided. The two push rods 208 are arranged opposite each other on the bearing seat 204 along the first direction. The distance between the two push rods 208 is smaller than the diameter of the object to be tested, which can prevent material leakage.

[0079] The push rod 208 is connected to the adjusting cylinder 207. The adjusting cylinder 207 can drive the push rod 208 to move along the length of the guide baffle 205 and fix it in a preset position. The purpose is to adjust the position of the push rod 208 relative to the material to be picked up station. It can be understood that by adjusting the position of the push rod 208 relative to the material to be picked up station, the center of the object to be inspected can be made to coincide with the center of the material to be picked up station after the object to be inspected comes into contact with the push rod 208, so as to facilitate the subsequent transfer of the object to be inspected.

[0080] The preset position is the location of the push rod 208 that abuts against the object to be tested when the center of the object to be tested coincides with the center of the material picking station.

[0081] Specifically, the adjusting cylinder 207 can be a slide cylinder. The adjusting cylinder 207 is mounted on the first surface 2041 of the bearing seat 204 via the cylinder fixing plate 4032. The top of the adjusting cylinder 207 is provided with a push rod 208 mounting plate. The push rod 208 is mounted on the push rod 208 mounting plate. The adjusting cylinder 207 can drive the push rod 208 mounting plate to move, so as to drive the push rod 208 to move through the push rod 208 mounting plate, thereby achieving the purpose of adjusting the position of the push rod 208.

[0082] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 3 As shown, the feeding mechanism 200 also includes an adjusting plate 209 and an idler wheel 210. The adjusting plate 209 is disposed on the first surface 2041 of the bearing seat 204, and the idler wheel 210 is rotatably disposed on the adjusting plate 209 and connected to the belt conveyor assembly 203.

[0083] By setting the idler pulley 210, slippage of the belt 2033 during movement can be prevented, which can improve the stability of the belt conveyor assembly 203 and thus improve the stability of the movement of the object to be tested.

[0084] Two idler pulleys 210 can be provided. The two idler pulleys 210 are arranged opposite each other on both sides of the belt 2033 along the first direction and are respectively connected to the belt 2033.

[0085] Specifically, the adjusting plate 209 is horizontally mounted on the first surface 2041 of the bearing seat 204, and the idler wheel 210 is rotatably mounted on the adjusting plate 209 via the idler wheel 210 shaft. The idler wheel 210 shaft is perpendicular to the adjusting plate 209, and the idler wheel 210 is mounted on the top of the idler wheel 210 shaft.

[0086] It is understandable that when the belt 2033 moves, it can drive the idler wheel 210 to rotate. The idler wheel 210 has the function of preventing deviation and can limit the belt 2033 in the first direction.

[0087] In some possible implementations provided in this disclosure, see [link to relevant documentation].

The transport module 503 drives the adsorption unit 504 to move along the X-axis, Y-axis, or Z-axis, thereby moving the object to be tested through the adsorption unit 504 and achieving the purpose of transferring the object to be tested. In this application, the transport module 503 moves the object to be tested in three-dimensional space through the adsorption unit 504, which can avoid damage to the object to be tested and improve the product yield; at the same time, it can optimize the transfer process of the object to be tested, so as to make the multi-station testing equipment compact.

[0098] Z-axis base plate 5034 is slidably mounted on X-axis base plate 5031 via X-axis linear guide rail 5032 and X-axis drive mechanism 5033. Z-axis base plate 5034 can move along the X-axis direction.

[0099] The Y-axis base plate 5037 is slidably mounted on the Z-axis base plate 5034 via the Z-axis linear guide rail 5035 and the Z-axis drive mechanism 5036. The Y-axis base plate 5037 can move along the Z-axis direction. The Y-axis connecting plate 5038 is connected to the Y-axis base plate 5037.

The Y-axis drive mechanism 5039 is also connected to the adsorption unit 504. The Y-axis drive mechanism 5039 is used to drive the adsorption unit 504 to move along the Y-axis direction.

[0100] The X-axis base plate 5031 can be a rectangular metal plate. The X-axis base plate 5031 is slidably mounted on the first column 501 and the second column 502 via the lifting drive assembly 505 and the lifting linear guide rail 506.

[0101] The X-axis linear guide 5032 can be a circular arc groove linear guide or a Gothic groove linear guide, etc. In this embodiment, the X-axis linear guide 5032 is a circular arc groove linear guide, which is mounted on the top of the X-axis base plate 5031 and extends along the X-axis direction.

[0102] The X-axis drive mechanism 5033 can be a linear module. The X-axis drive mechanism 5033 is mounted on the X-axis base plate 5031 and is located below the X-axis linear guide rail 5032. The X-axis drive mechanism 5033 extends along the length direction of the X-axis linear guide rail 5032.

[0103] The Z-axis base plate 5034 can be a rectangular metal plate. The Z-axis base plate 5034 is slidably mounted on the X-axis base plate 5031 along the X-axis direction through the X-axis drive mechanism 5033 and the X-axis linear guide rail 5032.

[0104] The Z-axis linear guide 5035 can be a circular arc groove linear guide or a Gothic groove linear guide, etc. In this embodiment, the Z-axis linear guide 5035 is a circular arc groove linear guide. The Z-axis linear guide 5035 is disposed on the side of the Z-axis base plate 5034 opposite to the X-axis base plate 5031 and extends along the Z-axis direction. Specifically, two Z-axis linear guides 5035 can be provided, and the two Z-axis linear guides 5035 are arranged opposite each other along the X-axis direction to improve the stability of the movement of the adsorption unit 504.

[0105] The Z-axis drive mechanism 5036 can be a cylinder, and the Z-axis drive mechanism 5036 is arranged between two Z-axis linear guides 5035 and extends along the Z-axis direction.

[0106] The Y-axis base plate 5037 can be a rectangular metal plate, and the Y-axis base plate 5037 is slidably mounted on the Z-axis base plate 5034 along the Z-axis direction through the Z-axis drive mechanism 5036 and the Z-axis linear guide rail 5035.

[0107] The Y-axis connecting plate 5038 can be a long strip of metal plate, which is installed at the bottom of the Y-axis base plate 5037 and extends along the X-axis direction. Specifically, the Y-axis connecting plate 5038 is perpendicular to the Y-axis base plate 5037.

[0108] The Y-axis drive mechanism 5039 can be a slide cylinder. The Y-axis drive mechanism 5039 is installed on the side of the Y-axis connecting plate 5038 near the object to be tested.

[0109] Specifically, the handling module 503 also includes a suction cup mounting plate. The first end of the suction cup mounting plate is connected to the adsorption unit 504, and the second end is connected to the Y-axis drive mechanism 5039. The Y-axis drive mechanism 5039 is used to drive the suction cup mounting plate to move, so as to drive the adsorption unit 504 to move through the suction cup mounting plate.

[0110] In this embodiment of the application, five Y-axis drive mechanisms 5039 are provided. The five Y-axis drive mechanisms 5039 are evenly arranged along the length direction of the Y-axis connecting plate 5038. Each of the five Y-axis drive mechanisms 5039 is connected to an adsorption unit 504 through a suction cup mounting plate.

[0111] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 4 and Figure 5 As shown, the first positioning mechanism 300 includes a first front turntable 301, a first rotating component 302, and a first positioning component 303. The first front turntable 301 has two first receiving slots for placing the object to be tested. The two first receiving slots are located at the receiving station and the testing station, respectively. The receiving station and the testing station are arranged opposite to each other along the radial direction of the first front turntable 301. The first positioning component 303 is disposed on the first rotating component 302 for receiving and clamping the object to be tested. The first rotating component 302 is connected to the first front turntable 301 and is disposed on the side of the first front turntable 301 near the frame 100. It is used to drive the first front turntable 301 to rotate so as to move the object to be tested located at the receiving station to the testing station.

[0112] By setting the first positioning mechanism 300, the object to be tested can be accurately positioned, so that the position of the object to be tested can be quickly adjusted to a good state, meeting the needs of positioning adjustment of the object to be tested, improving the efficiency of subsequent testing, and ensuring positioning accuracy.

[0113] The first front turntable 301 is roughly disc-shaped, and a first receiving groove is provided on the top of the first front turntable 301 for placing the object to be tested.

[0114] Specifically, the top of the first front turntable 301 has two first receiving slots, which are arranged opposite each other along the radial direction of the first front turntable 301. Further, one first receiving slot is located at the receiving station and is used to receive the material to be tested; the other first receiving slot is located at the testing station and is used to test the material to be tested.

[0115] The receiving station can be set up opposite the station to be picked up in the second direction.

[0116] The inspection station can be set up opposite the inspection end of the visual inspection agency in the first direction.

[0117] The first positioning component 303 can be a push-pull clamping component, used to receive and clamp the object to be tested located in the first receiving slot at the receiving station.

[0118] The first rotating component 302 can be a belt-driven rotating drive component 2033. The first rotating component 302 is located on the side of the first front turntable 301 near the frame 100. The first front turntable 301 is connected to the drive end of the first rotating component 302. The first rotating component 302 is used to drive the first front turntable 301 to rotate around the axis of the first front turntable 301 as the rotation center, so as to drive the object to be tested from the receiving station to the testing station through the first front turntable 301.

[0119] Specifically, the first positioning component 303 is disposed on the first rotating component 302 so that the structure of the first positioning mechanism 300 can be more compact, thereby reducing the volume of the first positioning mechanism 300 and increasing the applicability of the first positioning mechanism 300 to meet user needs.

[0120] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 4 and Figure 5 As shown, the first rotating assembly 302 includes a first support frame 3021, a first rotating motor 3022, and a first rotating shaft 3023. The first support frame 3021 is provided with a second through hole 30211 and a third through hole 30212. A first bearing 3024 is provided in the third through hole 30212. The first rotating motor 3022 is mounted on the first support frame 3021. The drive end of the first rotating motor 3022 passes through the second through hole 30211. The first rotating shaft 3023 passes through the inner ring of the first bearing 3024. The first rotating shaft 3023 is connected to the drive end of the first rotating motor 3022 through a first transmission part 3025. The end of the first rotating shaft 3023 away from the first support frame 3021 is fixedly connected to the first front turntable 301 through a first fixing clamp 3026.

[0121] The output shaft of the first rotary motor 3022 passes through the second through hole 30211, and the first rotary shaft 3023 passes through the third through hole 30212 via the first bearing 3024. The first rotary motor 3022 is connected to the first rotary shaft 3023 via the first transmission part 3025, so that the rotation of the output shaft of the first rotary motor 3022 drives the rotation of the first rotary shaft 3023, and then drives the rotation of the first front turntable 301 on the first rotary shaft 3023, so that the object to be tested on the first front turntable 301 can be moved, so that the object to be tested can move from the receiving station to the testing station.

[0122] It should be noted that the first fixing clamp 3026 has an open side, which is fitted onto the first rotating shaft 3023. The open side is locked by bolts, so that the first fixing clamp 3026 hugs the first rotating shaft 3023. The diameter of the bolt on the open side is perpendicular to the diameter of the first fixing clamp 3026. The first fixing clamp 3026 is also provided with multiple bolt holes, the axis of which is parallel to the axis of the first fixing clamp 3026. Bolts are installed in the bolt holes, and the first fixing clamp 3026 is fixedly connected to the first front turntable 301 by the bolts. The first fixing clamp 3026 enables the first rotating shaft 3023 to drive the first front turntable 301 to rotate. Furthermore, the connection between the first rotating shaft 3023 and the first front turntable 301 by the first fixing clamp 3026 facilitates disassembly and maintenance, and allows for fine adjustment of the installation accuracy of the first front turntable 301, thereby improving the positioning accuracy of the first positioning mechanism 300.

[0123] Specifically, a retaining ring for the first bearing 3024 is provided at the lower end of the first bearing 3024 inside the third through hole 30212, that is, on the side of the first bearing 3024 away from the first front turntable 301. The retaining ring for the first bearing 3024 is sleeved on the first rotating shaft 3023. After being locked by the screws on the retaining ring for the first bearing 3024, the retaining ring for the first bearing 3024 hugs the first rotating shaft 3023. This setting plays a limiting role for the first bearing 3024, preventing the first bearing 3024 from coming out of the third through hole 30212 due to vibration generated during rotation, and ensuring the working stability of the first positioning mechanism 300.

[0124] The first transmission unit 3025 includes a first transmission wheel 30251, a second transmission wheel 30252, and a first transmission belt 30253.

[0125] Specifically, the first transmission wheel 30251 is coaxially mounted on the output shaft of the first rotary motor 3022, and the second transmission wheel 30252 is fixed on the first rotating shaft 3023. The first transmission wheel 30251 and the second transmission wheel 30252 are connected by the first transmission belt 30253, so that the rotation of the output shaft of the first rotary motor 3022 can drive the rotation of the first rotating shaft 3023. It should be noted that the first transmission belt 30253 has teeth (tooth-like protrusions) on the side facing the first transmission wheel 30251 and the second transmission wheel 30252. The first transmission wheel 30251 and the second transmission wheel 30252 are both synchronous pulleys, and the synchronous pulleys have rotating teeth (including tooth grooves and protrusions) that match the belt teeth. By matching the belt teeth and the rotating teeth, the transmission accuracy of the first transmission part 3025 is improved.

[0126] Understandably, the transmission form of the first transmission unit 3025 is easier to install and adjust, saving time and effort; there is no transmission gap, improving transmission accuracy; the matching use of the first transmission wheel 30251, the second transmission wheel 30252 and the first transmission belt 30253, during the transmission process, the first transmission belt 30253 is an elastic component with a certain buffering effect, which can reduce vibration and improve the stability of the first transmission unit 3025 operation on the one hand, and reduce noise on the other hand.

[0127] The first transmission unit 3025 also includes a first tensioning wheel 30254.

[0128] Specifically, the first tensioning pulley 30254 is mounted on a first tensioning pulley 30254 seat, which is mounted on the first support frame 3021, and is located below the first transmission belt 30253. Since the first transmission belt 30253 is an elastic component, it will loosen after a certain period of transmission. If the first transmission belt 30253 loosens, during transmission, the teeth on the first transmission belt 30253 will climb onto the top circles of the pulleys of the first transmission wheel 30251 and the second transmission wheel 30252, and instantly move past the top circles of the pulleys to the adjacent tooth grooves, thus generating transmission errors and affecting the output torque of the first rotary motor 3022. Therefore, the first transmission part 3025 is also provided with a first tensioning pulley 30254 seat and a first tensioning pulley 30254. When the first transmission belt 30253 becomes loose, the position of the first tensioning pulley 30254 on the first tensioning pulley 30254 seat is adjusted so that the first tensioning pulley 30254 moves toward the first transmission belt 30253, thereby increasing the tension of the first transmission belt 30253 and further improving the transmission accuracy of the first transmission part 3025.

[0129] The line connecting the axis of the first transmission wheel 30251 and the axis of the second transmission wheel 30252 can be set at any angle to the seat of the first tension wheel 30254. In this embodiment, the seat of the first tension wheel 30254 is set perpendicular to the line connecting the axis of the first transmission wheel 30251 and the axis of the second transmission wheel 30252. The perpendicular angle setting makes it easier to adjust the first tension wheel 30254, improves the tensioning efficiency of the first transmission belt 30253, and thus improves the transmission efficiency of the first transmission part 3025.

[0130] The first rotating assembly 302 also includes a first slip ring 3027, which can be an electric slip ring. The first slip ring 3027 is fixedly mounted on a first slip ring 3027 bracket. The first slip ring 3027 bracket is fixedly connected to the first support frame 3021. The first slip ring 3027 bracket is located on the same side as the first rotating motor 3022. The rotor of the first slip ring 3027 is fixedly connected to the first rotating shaft 3023.

[0131] Specifically, the rotor of the first slip ring 3027 is fixedly connected to the first rotating shaft 3023. The first slip ring 3027 is connected to the first sensor 304 through a signal line. Passing the signal line through the first slip ring 3027 ensures that the signal line can rotate continuously with the rotating shaft and also avoids the signal line from breaking due to continuous rotation, thus improving the service life of the signal line. This, in turn, improves the working stability and continuity of the first positioning mechanism 300. At the same time, the first slip ring 3027 also has a strong signal transmission capability, which can improve the start-stop efficiency of each component, thereby improving the detection efficiency of the first positioning mechanism 300 after positioning.

[0132] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 4 and Figure 5 As shown, the first positioning component 303 includes a first cylinder support block 3031, a first push cylinder 3032, a first lifting cylinder 3033, a first return spring 3034, and a first rear fixed stop 3035 and a first movable stop 3036 that are arranged opposite to each other in the radial direction of the first front turntable 301.

[0133] A first groove 3011 is formed on the first front turntable 301, and a first slide rail 3012 is provided in the first groove 3011. A first movable stop block 3036 is set on the first slide rail 3012 via a first slider. First mounting slots are provided at both ends of the first groove 3011 for installing a first rear fixed stop 3035. A first cylinder support block 3031 is set on a first support frame 3021. A first push cylinder 3032 is set on the top of the first cylinder support block 3031. A first pusher block 3037 is provided at the extended end of the first push cylinder 3032. First strip-shaped passages are provided on both sides of the first groove 3011. The first movable stop 3036 has a first protrusion 30361, which passes through the first strip-shaped through hole. The first push cylinder 3032 can drive the first pusher block 3037 to extend and push the first protrusion 30361 to move in the first strip-shaped through hole toward the direction away from the first rear fixed stop 3035. The first end of the first return spring 3034 is connected to the first rear fixed stop 3035, and the second end is connected to the first movable stop 3036. When the first movable stop 3036 moves toward the direction away from the first rear fixed stop 3035, the first return spring 3034 accumulates elastic potential energy.

[0134] The first lifting cylinder 3033 is located on the opposite side of the second direction of the first cylinder support block 3031. The extended end of the first lifting cylinder 3033 is provided with a first tray 3038. The first tray 3038 is arranged opposite to the receiving station in the vertical direction. The first lifting cylinder 3033 is used to drive the first tray 3038 to rise and fall to receive the inspection object.

[0135] The first support frame 3021 is mounted on the frame 100, the first cylinder support block 3031 is mounted on the first support frame 3021, and the first push cylinder 3032 is horizontally mounted on top of the first cylinder support block 3031. The first push cylinder 3032 is located below the first front turntable 301, meaning that the first pusher block 3037, which is located at the extended end of the first push cylinder 3032, is also located below the first front turntable 301. The end of the first protrusion 30361 away from the first movable stop 3036 can extend to the bottom of the first front turntable 301 through the first strip-shaped through hole opened on the first front turntable 301, so that the first protrusion 30361 and the first pusher block 3037 are located in the same plane. The movement of the first pusher block 3037 can contact the first protrusion 30361 and push the first protrusion 30361 to move.

[0136] The first push cylinder 3032 is supported by the first cylinder support block 3031, which ensures that the first pusher at the front end of the first push cylinder 3032 can contact the first protrusion 30361, thereby improving the stability of the first push cylinder 3032 in pushing the first movable stop 3036 to move.

[0137] Specifically, the first pushing cylinder 3032 can be a slide cylinder. The first pushing cylinder 3032 can drive the first pushing block 3037 to move, so that the first pushing block 30361 can move through the first pushing block 3037, causing the first protrusion 30361 to drive the first movable stop 3036 to move away from the first rear fixed stop 3035 on the first slide rail 3012. The first protrusion 30361 moves within the range of the first strip-shaped through hole, thereby limiting the movement range of the first movable stop 3036 and improving the safety of the movement of the first movable stop 3036. The setting of the first slide rail 3012 can improve the stability and smoothness of the movement of the first movable stop 3036.

[0138] The first return spring 3034 has a first spring support at each end, the two first spring supports are located on the same side, and the two spring supports are respectively set on the first rear fixed stop and the first movable stop 3036.

[0139] Specifically, the first push cylinder 3032 pushes the first movable stop 3036, which in turn moves the first movable stop 3036 away from the first rear fixed stop edge 3035. This facilitates the placement of the object to be tested into the first receiving groove without friction with the object, thus avoiding damage. The first return spring 3034 improves the buffering of the object to be tested when the first movable stop 3036 returns to its original position, preventing secondary damage. At the same time, the first push cylinder 3032 and the first return spring 3034 can also achieve rapid positioning of the object to be tested, improving testing efficiency.

[0140] The first lifting cylinder 3033 can be a slide cylinder. The first lifting cylinder 3033 is vertically installed on the opposite side of the second direction of the first cylinder support block 3031. The extended end of the first lifting cylinder 3033 is provided with a first tray 3038. The first tray 3038 is arranged opposite to the receiving station in the vertical direction. The receiving station is provided with a through hole.

[0141] Specifically, while the first push cylinder 3032 pushes the first movable stop 3036 to move away from the first rear fixed stop 3035, the first lifting cylinder 3033 can drive the first tray 3038 to rise through the through hole, so that the first tray 3038 can move to the top of the first front turntable 301 to receive the test object.

[0142] In this application, the working principle of the first positioning mechanism 300 is as follows: First, the first push cylinder 3032, which is installed horizontally, drives the first push block 3037 to extend and push the first movable stop block 3036 through the first protrusion block 30361 to open the first receiving groove on the receiving station. Then, the first lifting cylinder 3033, which is installed vertically, drives the first tray 3038 to rise through the through hole opened in the receiving station to receive the inspection. Then, the first lifting cylinder 3033, which is installed vertically, drives the first tray 3038 to lower so that the object to be inspected on the first tray 3038 can fall into the first receiving groove. Then, the first push cylinder 3032, which is installed horizontally, is controlled to return to the initial state. At this time, the first movable stop block 3036 rebounds under the action of the first reset spring 3034 and clamps the object to be inspected. Finally, the first front turntable 301 is driven to rotate 180° through the first rotating component 302 so that the object to be inspected moves from the receiving station to the inspection station.

[0143] In some possible embodiments provided in this disclosure, the first rear fixed stop 3035 and the first movable stop 3036 are made of polyetheretherketone (PEEK).

[0144] Specifically, the first rear fixed edge 3035 and the first movable stop 3036 in this application are made of special engineering plastics. The special engineering plastic used in this embodiment is polyaryletherketone (PAEK). Polyaryletherketone mainly includes polyetheretherketone (PEEK), polyetherketone (PEK), polyetherketoneketone (PEKK), polyetheretherketoneketone (PEEKK), and polyetherketoneetherketoneketone (PEKEKK). Furthermore, in this embodiment, polyetheretherketone (PEEK) is used to make the first rear fixed edge 3035 and the first movable stop 3036. PEEK has good mechanical strength and good wear resistance, which can avoid wear and scratches on the edge of the object to be tested during contact.

[0145] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 4 As shown, the first positioning mechanism 300 includes a first sensor 304, which is disposed on the first front turntable 301. The first sensor 304 is used to sense the position information of the object to be detected.

[0146] The sensing end of the first sensor 304 faces the first receiving groove, and the sensing end of the first sensor 304 is located between the first rear fixed stop 3035 and the first movable stop 3036.

[0147] Specifically, by setting a first sensor 304 between the first rear fixed stop 3035 and the first movable stop 3036, the position of the object to be detected can be monitored. When the signal of the first sensor 304 is blocked, it indicates that the object to be detected has been placed in the first receiving groove. In this way, the first push cylinder 3032 can be controlled to return to the initial state, so that the first movable stop 3036 moves toward the first rear fixed stop 3035 under the action of the first reset spring 3034 to clamp the object to be detected. Conversely, when the signal of the first sensor 304 is not blocked, the first push cylinder 3032 is controlled to extend, and the first movable stop 3036 moves away from the first rear fixed stop 3035 to perform subsequent feeding operations.

[0148] It is understood that the first sensor 304 is mounted on the first front turntable 301 via a first sensor 304 bracket. The first sensor 304 bracket is fixed to the first front turntable 301. The first sensor 304 bracket has a through hole through which the first sensor 304 passes and is aligned with the first receiving groove. The first sensor 304 is connected to the first slip ring 3027 via a signal line, ensuring that the signal transmission of the first sensor 304 is not affected when the first front turntable 301 rotates, thereby improving the stability of the first sensor 304's operation.

[0149] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 6 As shown, the second positioning mechanism 400 includes a second front turntable 401, a second rotating component 402, and a second positioning component 403. The second rotating component 402 includes a second support frame 4021, and the second positioning component 403 includes a cylinder fixing plate 4032 and a second pushing cylinder 4033. The cylinder fixing plate 4032 is disposed on the first direction side of the second support frame 4021. The cylinder fixing plate 4032 includes a first side 40321 and a second side 40322 that are vertically disposed. The first side 40321 is fixedly connected to one side of the second support frame 4021, and the second pushing cylinder 4033 is disposed on the second side 40322. A second pushing block 4038 is disposed on the extended end of the second pushing cylinder 4033.

[0150] The second front turntable 401 has the same structure as the first front turntable 301, and will not be described in detail here.

[0151] The second rotating mechanism has the same structure and working principle as the first rotating mechanism, so it will not be described again here.

[0152] The second positioning component 403 is similar to the first positioning component 303, except that the second positioning component 403 removes the first lifting cylinder 3033 and the first tray 3038 that are vertically installed in the first positioning component 303, and adds a second pushing cylinder 4033 which is set on one side of the second support seat through the cylinder fixing plate 4032 and located below the second front turntable 401.

[0153] The second positioning component 403 also includes a third push cylinder 4034, which is equivalent to the first push cylinder 3032. In other words, there are two push cylinders below the second front turntable 401 in the second positioning mechanism 400.

[0154] Specifically, both the extended ends of the second pushing cylinder 4033 and the third pushing cylinder 4034 are equipped with second pushing blocks 4038. The second pushing cylinder 4033 moves the second movable stop 4037 on the receiving station to open the second receiving groove on the receiving station; the third pushing cylinder 4034 moves the second movable stop 4037 on the inspection station to open the second receiving groove on the inspection station, allowing the vision inspection mechanism to continue inspecting the sidewall of the object to be inspected, thereby improving the accuracy of the inspection results.

[0155] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 1 As shown, the detection channel also includes a material transfer mechanism 600. The plane where the material transfer mechanism 600 is located is parallel to the plane where the first positioning mechanism 300 and the second positioning mechanism 400 are located. The material transfer mechanism 600 is disposed between the first positioning mechanism 300 and the second positioning mechanism 400. The material transfer mechanism 600 is used to receive and transfer the object to be tested.

[0156] By setting up a material transfer mechanism 600, the object to be tested can be transferred from the first frame 101 to the second frame 102.

[0157] The material transfer mechanism 600 is located between the first frame 101 and the second frame 102, that is, between the four first positioning mechanisms 300 and the four positioning mechanisms. By setting the material transfer mechanism 600, it can receive the object to be tested on the first frame 101 and transfer it to the second frame 102.

[0158] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 8As shown, the material transfer mechanism 600 includes an intermediate turntable 601, a third support frame 602, a third rotary motor 603, and a third rotary shaft 604. Two platforms 6011 are arranged opposite each other on the intermediate turntable 601 for placing the objects to be tested. The third support frame 602 is provided with a sixth through hole 6021 and a seventh through hole 6022. A third bearing 606 is provided in the seventh through hole 6022. The third rotary motor 603 is mounted on the third support frame 602. The drive end of the third rotary motor 603 passes through the sixth through hole 6021. The third rotary shaft 604 passes through the inner ring of the third bearing 606. The third rotary shaft 604 is connected to the drive end of the third rotary motor 603 through a third transmission part 605. The end of the third rotary shaft 604 away from the third support frame 602 is fixedly connected to the intermediate turntable 601 through a third fixing clamp 607.

[0159] The material transfer mechanism 600 also includes a third slip ring 608, which is mounted on a third slip ring 608 bracket. The third slip ring 608 bracket is fixedly connected to the third support frame 602. The third slip ring 608 bracket is located on the same side as the third rotary motor 603. The rotor of the third slip ring 608 is fixedly connected to the third rotary shaft 604.

[0160] The intermediate turntable 601 is roughly disc-shaped and is used to hold the object to be tested.

[0161] Specifically, two stages 6011 are provided on the intermediate turntable 601. The two stages 6011 are arranged opposite each other along the radial direction of the intermediate turntable 601, and the stages 6011 provide a stable placement position for the object to be tested.

[0162] The third support frame 602, the third rotary motor 603, the third rotary shaft 604 and the third transmission part 605 together form a rotary drive assembly. The intermediate turntable 601 is connected to the rotary drive assembly. The rotary drive assembly is used to drive the intermediate turntable 601 to rotate. The rotary drive assembly has the same structure and working principle as the first rotary assembly 302, so it will not be described in detail here.

[0163] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 1 and Figure 9As shown, the detection channel also includes a lifting and rotating mechanism 700. The lifting and rotating mechanism 700 is located on the side of the second positioning mechanism 400 near the frame 100. The lifting and rotating mechanism 700 includes a third column 701, a rotating plate 702, and a lifting and rotating module 703. The third column 701 is located on the frame 100. A linear module 704 is located on the side of the third column 701 near the rotating plate 702. The rotating plate 702 is slidably mounted on the third column 701 through the linear module 704. The lifting and rotating module 703 is connected to the rotating plate 702 and is located on the side of the rotating plate 702 away from the third column 701. The driving end of the lifting and rotating module 703 is vertically opposite to the detection station. The lifting and rotating module 703 is used to drive the object to be detected to rise, fall, and rotate during the detection process.

[0164] By setting up a lifting and rotating mechanism 700, the object to be inspected can be driven to rise, fall, and rotate during the inspection process, so that the visual inspection mechanism can inspect the outer wall of the object to be inspected, thereby improving the accuracy of the inspection results.

[0165] The third column 701 can be a rectangular steel pipe. The third column 701 is vertically fixed on the second frame 102 and is used to support the lifting and rotating module 703.

[0166] Specifically, a linear module 704 is provided on the side of the third column 701 near the lifting and rotating module 703, and the linear module 704 extends vertically. The lifting and rotating module 703 is slidably mounted on the third column 701 via the linear module 704. By setting the linear module 704, the lifting and rotating module 703 can be moved vertically, which facilitates subsequent adjustment and maintenance of the lifting and rotating module 703.

[0167] The lifting and rotating mechanism 700 also includes a rotating plate 702, which can be a rectangular metal plate. The rotating plate 702 is disposed between the lifting and rotating module 703 and the third column 701. The lifting and rotating module 703 can be slidably disposed on the linear module 704 of the third column 701 via the rotating plate 702. The linear module 704 is used to drive the rotating plate 702 to move, so as to drive the lifting and rotating module 703 to move via the rotating plate 702.

[0168] The second positioning mechanism 400 also has a through hole at its testing station.

[0169] Specifically, the drive end of the lifting and rotating module 703 is located directly below the detection station on the second positioning mechanism 400. When the object to be inspected moves from the receiving station to the detection station on the second positioning mechanism 400, the drive end of the lifting and rotating module 703 can rise and rotate, thereby driving the object to be inspected on the detection station to rise and rotate. It should be noted that the drive end of the lifting and rotating module 703 is coaxially arranged with the object to be inspected at the detection station.

[0170] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 9 As shown, the lifting and rotating module 703 includes a rotating shaft base 7031, a lifting and rotating motor 7032, a transmission rotating shaft 7033, and a lifting rotating shaft 7034. The rotating shaft base 7031 is fixedly mounted on the rotating upright plate 702. The lifting and rotating motor 7032 is located at one end of the rotating upright plate 702. The transmission rotating shaft 7033 is located on the side of the rotating shaft base 7031 near the frame 100 and is connected to the drive end of the lifting and rotating motor 7032 via a coupling 7035. The lifting rotating shaft 7034 is vertically positioned opposite the inspection station. The first end of the lifting rotating shaft 7034 is poweredly connected to the transmission rotating shaft 7033 via a magnetic wheel 7036, and the second end passes through the rotating shaft base 7031. The lifting and rotating motor 7032 drives the transmission rotating shaft 7033 to rotate, thereby driving the lifting rotating shaft 7034 to rise, fall, and rotate via the magnetic wheel 7036.

[0171] Among them, the lifting rotary motor 7032 can be a servo motor.

[0172] Specifically, the lifting rotary motor 7032 is mounted on one end of the rotating vertical plate 702 via a motor mounting plate. The transmission rotary shaft 7033 is connected to the output shaft of the lifting rotary motor 7032 via a coupling 7035 and passes through the drive shaft seat and fixing ring installed below the rotating shaft base 7031. The lower end of the lifting rotary shaft 7034 is connected to the transmission rotary shaft 7033 via a magnetic wheel 7036, and the upper end of the lifting rotary shaft 7034 passes through the rotating shaft base 7031.

[0173] In this embodiment of the application, four lifting and rotating shafts 7034 are provided, and the four lifting and rotating shafts 7034 are set one-to-one with the detection stations on the four second positioning mechanisms 400.

[0174] In this application, the working principle of the lifting and rotating mechanism 700 is as follows: the lifting and rotating motor 7032 can drive the transmission rotating shaft 7033 installed on the rotating shaft base 7031 to rotate through the coupling 7035. The rotation of the transmission rotating shaft 7033 can drive the lifting rotating shaft 7034 to rise and rotate through the magnetic wheel 7036, so that the lifting rotating shaft 7034 passes through the through hole on the detection station on the second front turntable 401, driving the object to be detected to rise and rotate at the same time.

[0175] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 1 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the detection channel also includes a first visual detection mechanism 800, a second visual detection mechanism 900, a third visual detection mechanism 1000 and a fourth visual detection mechanism 1100. The first visual detection mechanism 800 and the second visual detection mechanism 900 are disposed on the first direction side of the first positioning mechanism 300, and the third visual detection mechanism 1000 and the fourth visual detection mechanism 1100 are disposed on the first direction side of the second positioning mechanism 400.

[0176] The first visual inspection mechanism 800 includes a first camera light source assembly 801, a second camera light source assembly 802, and a third camera light source assembly 803. The second visual inspection mechanism 900 includes a fourth camera light source assembly 901. The first camera light source assembly 801, the second camera light source assembly 802, the third camera light source assembly 803, and the fourth camera light source assembly 901 are arranged in a one-to-one correspondence with the four first positioning mechanisms 300 in the first direction.

[0177] The third visual inspection mechanism 1000 and the fourth visual inspection mechanism 1100 are separated by a second positioning mechanism 400. The third visual inspection mechanism 1000 includes a fifth camera light source assembly 1001, and the fourth visual inspection mechanism 1100 includes a sixth camera light source assembly 1101 and a seventh camera light source assembly 1102. The fifth camera light source assembly 1001, the sixth camera light source assembly 1101 and the seventh camera light source assembly 1102 are arranged in a one-to-one correspondence with the three second positioning mechanisms 400 in the first direction.

[0178] The first visual inspection mechanism 800 and the second visual inspection mechanism 900 are fixedly mounted on the first frame 101. The first visual inspection mechanism 800 is used to inspect the upper surface of the object to be inspected, and the second visual inspection mechanism 900 is used to inspect the lower surface of the object to be inspected.

[0179] Specifically, the first camera light source assembly 801, the second camera light source assembly 802, and the third camera light source assembly 803 are respectively arranged above the detection stations of the first three first positioning mechanisms 300 and facing the upper surface of the object to be detected; the fourth camera light source assembly 901 is arranged below the detection station of the fourth first positioning mechanism 300 and facing the lower surface of the object to be detected.

[0180] The third vision inspection mechanism 1000 and the fourth vision inspection mechanism 1100 are fixedly mounted on the second frame 102. The third vision inspection mechanism 1000 and the fourth vision inspection mechanism 1100 are used to inspect the outer wall of the object to be inspected from different angles.

[0181] Specifically, the fifth camera light source assembly 1001 is positioned directly above the detection station of the first second positioning mechanism 400 and faces the upper surface of the object to be detected; the sixth camera light source assembly 1101 and the seventh camera light source assembly 1102 are positioned above the detection stations of the latter two second positioning mechanisms 400 respectively, and are set at an angle to the object to be detected, so that the outer wall of the object to be detected can be detected from different angles.

[0182] It is understandable that the second positioning mechanism 400 does not have a corresponding visual inspection mechanism. If there are other defects to be detected, a separate visual inspection mechanism can be added.

[0183] In some possible implementations provided in this disclosure, see [link to relevant documentation]. Figure 1 and Figure 14 As shown, the detection channel also includes a discharge mechanism 1200, which is located on the second direction side of the second positioning mechanism 400. The discharge mechanism 1200 is used to receive the test object after detection and transport the test object out of the detection channel.

[0184] The discharge mechanism 1200 is similar in structure to the feeding mechanism 200, except that the discharge mechanism 1200 does not have an adjusting cylinder 207 and a pusher rod 208 installed. After the object to be tested enters the discharge mechanism 1200, it flows on the belt 2033 of the discharge mechanism 1200 to be transported out of the testing channel. The structure and working principle of the discharge mechanism 1200 will not be described in detail here.

[0185] Working principle:

[0186] The object to be tested is fed from the feeding mechanism 200. After being guided by the guide baffle 205 and guide edge 206 in the feeding mechanism 200, the object's position is adjusted. Upon contact with the push rod 208, the object stops moving. The adsorption unit 504 in the material handling mechanism 500, in conjunction with the material handling module 503, picks up the object and transfers it to the first positioning mechanism 300. After being positioned by the first positioning component 303, the first rotating component 302 drives the first front-end turntable 301 to rotate 180° to the first vision inspection mechanism 800 to complete the first inspection. After returning to its initial position, the object is transferred along the second direction by the material handling mechanism 500 to the next first positioning mechanism 300. This process is repeated for the second inspection by the first vision inspection mechanism 800. After the second inspection, the material handling mechanism 500 transfers the object to the next first positioning mechanism 300 and repeats the process for the third inspection. Finally, the material handling mechanism 500 transfers the object to the last first positioning mechanism 300. After completing the inspection by the second vision inspection mechanism 900 located below the first positioning mechanism 300, the device returns to its initial positioning position. The material handling mechanism 500 transfers the object to be inspected to the material transfer mechanism 600 located on the second frame 102. The platform 6011 drives the object to be inspected to rotate 180°. The material handling mechanism 500 on the second frame 102 then moves the object to be inspected along a straight line to the second positioning mechanism 400. The second positioning mechanism 400 positions the object and then rotates it 180° to reach the inspection position of the third vision inspection mechanism 1000. The lifting and rotating mechanism 700 located below the second positioning mechanism 400 drives the object to be inspected to rise and rotate through the lifting and rotating module 703. After completing the inspection, the object returns to its initial position and is transferred to the subsequent second positioning mechanism 400 via the material handling mechanism 500. The above operation is repeated to complete the two inspections of the fourth vision inspection mechanism 1100. Finally, the material handling mechanism 500 transfers the object to be inspected to the discharge mechanism 1200 to complete the discharge action.

[0187] The multi-station inspection equipment provided in the embodiments of the present invention, by setting two inspection channels and respectively setting four first positioning mechanisms 300 and four second positioning mechanisms 400 in the two inspection channels, enables the multi-station inspection equipment to complete the inspection of sixteen items in a single operation, which can effectively reduce the inspection time of a single item and improve the inspection efficiency, thereby effectively saving production costs and having good economic benefits; at the same time, the feeding mechanism 200, the material handling mechanism 500, the first positioning mechanism 300, the material transfer mechanism 600, the second positioning mechanism 400, the lifting and rotating mechanism 700, and the discharging mechanism 1200 adopt an integrated design, which can optimize the transfer process of the items to be inspected, making the equipment structure compact, and improving the automation level of the equipment.
