Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automotive parts, and particularly to a detection device and a detection method for an automotive dust cover. Background Technique
[0002] A dust cover is a commonly used item protection device, which is mainly used to prevent dust, gas, water droplets, etc. from entering the interior of the item. When the expansion slot on the automotive dashboard is not in use, it needs to be blocked by a dust cover. The dust cover is usually manufactured by injection molding. The edge of the completed dust cover usually has uneven burrs, which will cause the connection between the dust cover and the expansion slot to be not tight enough, resulting in gaps. Dust, gas, water droplets, etc. are likely to enter the expansion slot from the gaps. Therefore, the detection and analysis of the shape of the dust cover are particularly important, especially the detection and analysis of the state of the edge position of the dust cover. The dust cover with a neat edge and no burrs is a qualified product.
[0003] The existing dust cover detection technologies mainly adopt the following several methods: one is the detection method based on artificial vision, which relies on manual operation. Usually, it is to directly observe visually or shine a flashlight on the outer wall of the dust cover and then observe with the naked eye. The efficiency is low and it is easily affected by subjective factors; the other is the automated detection method based on multiple fixed industrial cameras. Although this method improves the detection efficiency, the flexibility of the equipment is poor and the cost is high. At the same time, when there are impurities such as dust attached to the dust cover, it may lead to false detection.
[0004] Regarding the above related technologies, there are still some deficiencies. Whether it is direct visual observation or shining a flashlight on the outer wall of the dust cover and then observing visually, these methods cannot detect those small burrs and are time-consuming and laborious. And the automated detection method based on multiple fixed industrial cameras has a high cost and may lead to false detection when there are impurities such as dust attached to the dust cover, and there is room for improvement Summary of the Invention
[0005] The purpose of the present invention is to provide a detection device and a detection method for an automotive dust cover to solve the problems raised in the above background technique.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a detection device for an automotive dust cover, comprising a detection module for detecting the appearance of the dust cover to be detected; a conveying device for receiving the dust cover to be detected and moving the dust cover to be detected into or out of the detection module; a suction component disposed beside the conveying device for sucking up impurities from the surface of the dust cover to be detected; a flipping mechanism mounted on the conveying device for clamping and flipping the dust cover to be detected so that the five detection surfaces of the dust cover to be detected can respectively face the detection end of the detection module; and a blowing component installed inside the detection module, the air outlet of the blowing component being inclined toward the dust cover to be detected and toward the outside of the detection module, wherein when the flipping mechanism drives the dust cover to be detected to flip, the five detection surfaces of the dust cover to be detected can respectively face the air outlet of the blowing component, and the airflow blown by the blowing component flows toward the suction end of the suction component.
[0007] By adopting the above technical solution, the conveying device carries the dust cover to be tested along a preset trajectory to the testing module. The suction component is located beside the conveying device and in front of the testing module, while the blowing component is located on the testing module near the input port. Before the dust cover to be tested enters the testing module, the suction component first adsorbs and collects the dust adhering to the surface of the dust cover, cleaning and collecting some of the attached dust and other impurities. Then, the conveying device continues to move along the preset trajectory, moving the dust cover to be tested into the testing module for testing. The flipping mechanism drives the dust cover to be tested to flip up, down, left, and right, and the blowing component starts blowing simultaneously. The surface of the dust cover to be tested is cleaned to remove any remaining firmly attached dust and other impurities. These impurities are then blown away by the airflow towards the outside of the testing module, effectively improving the accuracy of the testing module. This facilitates the analysis of defects in the dust cover's appearance, such as the presence of burrs, flash, or white spots, and avoids false or missed detections caused by surface contamination. Based on the test results, qualified and defective products are then sorted. Simultaneously, the suction component is activated to collect the dust and other impurities shaken off by the flipping mechanism and blown off by the blowing component, effectively preventing dust from spreading and contaminating other equipment.
[0008] Preferably, the flipping mechanism includes a support rod with one end fixedly connected to the conveying device and the other end rotatably connected to the top of the connecting rod, a telescopic drive member mounted on the support rod and with its telescopic end hinged to the other end of the connecting rod, a turntable fixedly connected to the side of the connecting rod away from the support rod, and a clamping assembly rotatably connected to the side of the turntable away from the support rod.
[0009] By adopting the above technical solution, a support rod is used as the skeleton of the flipping mechanism. The telescopic drive component is positioned and connected to provide support for the telescopic drive component, and it is ensured that the connecting rod does not deviate during the movement. The reciprocating extension and retraction of the telescopic drive component provides flipping power to the connecting rod, realizing the vertical rotation of the flipping mechanism. The rotation of the turntable drives the clamping assembly and the dust cover to be tested, which is fixed by the clamping assembly, to rotate, realizing the horizontal rotation of the flipping mechanism. In this way, the five surfaces to be tested of the dust cover can face the detection end of the detection module, realizing the use of a single camera to detect the appearance of the dust cover, effectively reducing the detection cost.
[0010] Preferably, the clamping assembly includes a clamping claw rotatably connected to the turntable, a second driving member mounted on one side of the clamping claw, a transmission screw rotatably connected to the power output end of the second driving member, the clamping claw having a fixed claw and a movable claw that reciprocates along the transmission screw, a first driving member being mounted on the side of the clamping claw away from the second driving member, and the first driving member being electrically connected to the turntable.
[0011] By adopting the above technical solution, the second driving component transmits power to drive the transmission screw to rotate. The transmission screw converts the rotational motion of the second driving component into a reciprocating motion that drives the movable claw to move back and forth in a straight line. As the transmission screw moves closer or further away, it cooperates with the fixed claw to grasp or release the dust cover to be tested. The first driving component is electrically connected to the turntable, thereby driving the rotating end of the turntable to rotate, which in turn drives the clamping assembly to rotate around the axis of the turntable, making it easy to adjust the clamping angle of the clamping claw.
[0012] Preferably, the detection module includes: a U-shaped shield, the conveying device being able to move the dust cover to be detected in and out of the U-shaped shield, and a detection camera being installed inside the U-shaped shield; the air blowing component is disposed inside the U-shaped shield.
[0013] By adopting the above technical solution, the conveying device carries the dust cover to be tested and moves along the preset track to smoothly enter the testing module. The testing camera takes pictures of the dust cover to be tested and performs image processing and defect analysis based on the results of the picture testing to distinguish between qualified products and defective products.
[0014] Preferably, the suction assembly includes a lifting telescopic component disposed on the preset track near the dust cover to be tested on the conveying device, an installation cylinder connected to the top of the telescopic end of the lifting telescopic component and extending along the conveying direction perpendicular to the conveying device, and a plurality of suction nozzles arranged along the extending direction of the installation cylinder and evenly spaced on the installation cylinder.
[0015] By adopting the above technical solution, the mounting cylinder can be raised and lowered vertically, which facilitates real-time adjustment of the mounting cylinder height according to the height position of the dust cover to be tested. This ensures that the distance between the suction nozzle and the surface of the dust cover to be tested remains constant. Multiple suction nozzles are evenly distributed on the adsorption surface of the mounting cylinder to form a continuous negative pressure zone with uniform adsorption force distribution. When the lifting telescopic component's conveying end descends, it drives the mounting cylinder to descend to a constant distance from the surface of the dust cover to be tested. The multiple suction nozzles adsorb and collect the dust attached to the surface of the dust cover to be tested, cleaning and collecting some of the attached dust and other impurities. When the lifting telescopic component's conveying end rises, it drives the mounting cylinder to rise and reset. The multiple suction nozzles effectively absorb the dust and other impurities that drift out from the testing module.
[0016] Preferably, the air blowing assembly includes a mounting plate installed remotely from the detection module, one or more air blowing nozzles disposed on the mounting plate, one air blowing nozzle disposed on the mounting plate, and a plurality of air blowing nozzles evenly spaced along the length direction of the mounting plate and embedded in the mounting plate.
[0017] By adopting the above technical solution, after the gas is ejected from the outlet of one or more air nozzles, it blows the surface of the dust cover to be tested, causing the dust and other impurities on the surface of the dust cover to drift outward with the airflow towards the outside of the detection module, and then causing the dust and other impurities to move towards the suction end of the suction component, and then be collected and stored by the suction component.
[0018] Preferably, the conveying device is a tank chain conveying device.
[0019] By adopting the above technical solution, the reciprocating linear motion of the conveying device is transformed into continuous rolling of the chain links by using an articulated structure similar to a tank chain, avoiding the sliding friction caused by traditional belt or gear transmission, effectively improving transmission efficiency, and protecting the internal cables and pipes of the conveying device from tangling during the movement of the conveying device.
[0020] Preferably, the detection device for the automobile dust cover further includes: a transfer platform for positioning the dust cover to be detected and adjusting the angle of the dust cover to be detected; a first loading robot for clamping the dust cover to be detected onto the transfer platform; and a second loading robot for clamping the dust cover to be detected on the transfer platform onto the flipping mechanism.
[0021] By adopting the above technical solution, the first feeding robot picks up the dust cover to be tested and places it on the transfer platform to realize automated feeding. The transfer platform temporarily stores and positions the dust cover to be tested and adjusts the angle of the dust cover to be tested to connect the gap between feeding and conveying. Then, the unloading robot transfers the dust cover to be tested on the transfer platform to the flipping mechanism on the conveying device. The flipping mechanism clamps and fixes the dust cover to be tested, and then the conveying device carries the dust cover to be tested along the preset trajectory to the testing module.
[0022] On the other hand, the automobile dust cover testing method provided in this application adopts the following technical solution: An automobile dust cover testing method includes the following steps: S11: The dust cover to be tested is held by the flipping mechanism; S12: The conveying device drives the flipping mechanism and the dust cover to be tested through the suction component, and the suction component performs preliminary dust suction on the dust cover to be tested. S13: The conveying device drives the flipping mechanism to enter the detection module, and the flipping mechanism drives the dust cover to be tested to rotate. At the same time, the detection module detects the surface of the dust cover to be tested, and the blowing assembly blows the surface of the dust cover to be tested. The blowing airflow flows to the outside of the detection module and is sucked up by the suction assembly.
[0023] On the other hand, based on the above technical solution, this application provides a method for testing automobile dust covers, which adopts the following technical solution: a method for testing automobile dust covers. The following steps precede step S11: S10. Provide a loading robotic arm to clamp the dust cover to be tested onto the flipping mechanism. Step S13 is followed by: S14: Provide a sorting robot arm, which sorts and unloads materials. The sorting robot arm performs actions according to the detection results, sorting and transferring qualified products to the packaging platform or placing them in the turnover device, and sorting and transferring defective products to the rework platform or placing them in the storage device.
[0024] By adopting the above technical solution, a loading robot arm picks up the dust cover to be inspected and transfers it to a flipping mechanism on a conveying device. The flipping mechanism clamps and fixes the dust cover to be inspected, and then the conveying device carries the dust cover to be inspected along a preset trajectory to the inspection module. Before the dust cover to be inspected enters the inspection module, the suction component first adsorbs and collects the dust adhering to the surface of the dust cover to be inspected, cleaning and collecting some of the attached dust and other impurities. Then, the conveying device continues to move along the preset trajectory, moving the dust cover to be inspected into the inspection module. The inspection module inspects the surface of the dust cover to be inspected. The flipping mechanism drives the dust cover to be inspected to flip up, down, left, and right. The blowing component is activated simultaneously to blow on the surface of the dust cover to be inspected, separating and cleaning the remaining firmly attached dust and other impurities on the surface of the dust cover to be inspected. The dust and other impurities are then blown away towards the outside of the inspection module with the blown airflow. Then, the sorting robot arm sorts qualified products and defective products according to the inspection results. At the same time, the suction component is activated simultaneously to collect the dust and other impurities shaken off by the flipping mechanism and blown off by the blowing component, effectively preventing dust from spreading everywhere and polluting or even affecting the operation of other equipment.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The shape of each dust cover is recorded by high-definition photography. Defects on the dust covers are then analyzed by comparing the photos. The air nozzles are designed to blow away dust from the dust covers under inspection, effectively improving the accuracy of the inspection and avoiding misjudgments of defects due to surface contamination of the dust covers. Dust and other impurities that drift out from the inspection module are absorbed and stored by the air intake. The flipping mechanism allows the inspection module to perform all-round inspection of the dust covers with just one industrial camera, effectively reducing costs and covering the blind spots of traditional single-sided inspection.
[0026] 2. By setting up a lifting and telescopic component, the mounting cylinder can be raised and lowered vertically, which makes it easy to adjust the height of the mounting cylinder in real time according to the height of the dust cover to be tested. This ensures that the distance between the air intake and the surface of the dust cover to be tested is constant, and better absorbs the dust attached to the dust cover. When the mounting cylinder rises and resets, it is in a higher position, so that multiple air intakes can effectively absorb the dust and other particles that drift out from the testing module.
[0027] 3. By setting the air outlet of the blowing component to be tilted towards the dust cover to be tested and towards the outside of the detection module, the dust and other impurities on the surface of the dust cover to be tested are caused to drift towards the outside of the detection module with the blown airflow, thereby causing the dust and other impurities to move towards the air intake end of the suction component, and then be collected and stored by the suction component.

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0031] like Figures 1-3 As shown in the embodiment of this application, a detection device for an automobile dust cover is disclosed, including a detection module 1 for detecting the appearance of the dust cover 2 to be detected, a conveying device 3 for receiving the dust cover 2 to be detected and moving the dust cover 2 to be detected into or out of the detection module 1, an air suction component 4 for absorbing impurities on the surface of the dust cover 2 to be detected is provided on the side of the conveying device 3, and a flipping mechanism 5 is also installed on the conveying device 3. The flipping mechanism 5 is used to clamp and flip the dust cover 2 to be detected so that the five surfaces to be detected of the dust cover 2 to be detected can face the detection end of the detection module 1 respectively; an air blowing component 6 is installed in the detection module 1, the air outlet of the air blowing component 6 is inclined towards the dust cover 2 to be detected and towards the outside of the detection module 1. When the flipping mechanism 5 drives the dust cover 2 to be detected to flip, the five surfaces to be detected of the dust cover 2 to be detected can face the air outlet of the air blowing component 6 respectively, and the airflow blown out by the air blowing component 6 flows to the air suction end of the air suction component 4.
[0032] like Figures 1-3As shown, the conveying device 3 carries the dust cover 2 to be tested along a preset trajectory to the testing module 1. The suction component 4 is located beside the conveying device 3 and in front of the testing module 1. The blowing component 6 is located on the testing module 1 near the input port. Before the dust cover 2 enters the testing module 1, the suction component 4 first adsorbs and collects the dust adhering to the surface of the dust cover 2, cleaning and collecting some of the attached dust and other impurities. Then, the conveying device 3 continues to move along the preset trajectory, moving the dust cover 2 into the testing module 1 for testing. The flipping mechanism 5 drives the dust cover 2 to flip up, down, left, and right, and the blowing component 6 starts simultaneously to blow the dust cover 2. The surface of the dust cover 2 is inspected, and any remaining firmly attached dust and other impurities are separated and cleaned. The dust and other impurities are then blown away by the airflow towards the outside of the inspection module 1, effectively improving the inspection accuracy of the inspection module 1. This facilitates the inspection module 1's analysis of defects in the appearance of the dust cover 2, such as whether there are burrs, flash, or white spots, avoiding false or missed detections caused by surface contamination of the dust cover 2. Based on the inspection results, qualified and defective products are sorted. At the same time, the suction component 4 is activated to collect the dust and other impurities that are shaken off by the flipping mechanism 5 and blown off by the blowing component 6, effectively preventing dust from spreading everywhere and polluting or even affecting the operation of other equipment.
[0033] Please see Figure 4 , Figure 5 and Figure 6 In this embodiment, the flipping mechanism 5 includes a support rod 52, one end of which is fixedly connected to the conveying device 3, and the other end of which is hinged to one end of the connecting rod 51. A telescopic drive member 53 is mounted on the support rod 52. The telescopic end of the telescopic drive member 53 is hinged to the other end of the connecting rod 51. A turntable 54 is fixedly connected to the side of the connecting rod 51 away from the support rod 52. A clamping assembly 55 is rotatably connected to the side of the turntable 54 away from the support rod 52. The support rod 52 serves as the skeleton of the flipping mechanism 5, positioning and connecting the telescopic drive member 53 to provide support for the telescopic drive member 53 and ensuring the connection rod 51 is secure. 1. No deviation occurs during movement; the reciprocating extension and retraction of the telescopic drive 53 provides the flipping power to the connecting rod 51, realizing the vertical rotation of the flipping mechanism 5. The rotation of the rotating end of the turntable 54 drives the clamping assembly 55 and the dust cover 2 to be tested fixed by the clamping assembly 55 to rotate, realizing the horizontal rotation of the flipping mechanism 5. In this way, the five surfaces to be tested of the dust cover 2 can be facing the detection end of the detection module 1 respectively, realizing the use of a single camera to detect the appearance of the dust cover 2 to be tested, effectively reducing the detection cost. The telescopic drive 53 is set as a telescopic cylinder.
[0034] Specifically, an elastic connector 56 is provided at one end of the support rod 52 near the telescopic drive member 53. The outer wall of the telescopic drive member 53 is sleeved in the elastic connector 56, and the elastic connector 56 is fixed to the end of the support rod 52. The outer wall of the telescopic drive member 53 is inserted into the elastic connector 56 to form a radial flexible connection. When the telescopic drive member 53 extends forward and pushes the connecting rod 51 to rotate upward, the telescopic drive member 53 is allowed to move away from the end of the support rod 52. When the telescopic drive member 53 retracts backward and drives the connecting rod 51 to rotate downward, the telescopic drive member 53 is allowed to move closer to the end of the support rod 52. This allows the telescopic drive member 53 to reciprocate forward or backward to provide the flipping power for the connecting rod 51.
[0035] Please continue reading. Figure 6 In this embodiment, the clamping assembly 55 includes a clamping jaw 551 rotatably connected to the turntable 54, and a second driving member 552 mounted on one side of the clamping jaw 551. A transmission screw 553 is rotatably connected to the power output end of the second driving member 552. The clamping jaw 551 has a fixed jaw 5511 and a movable jaw 5512 that reciprocates along the transmission screw 553. A first driving member 554 is mounted on the side of the clamping jaw 551 away from the second driving member 552. The first driving member 554 is electrically connected to the turntable 54 and is driven by the second driving member 551. 2. The transmission power drives the transmission screw 553 to rotate. The transmission screw 553 converts the rotational motion of the second driving member 552 into a reciprocating motion that drives the movable claw 5512 to move back and forth in a straight line. As the transmission screw 553 moves closer or further away, it cooperates with the fixed claw 5511 to grasp or release the dust cover 2 to be tested. The first driving member 554 is electrically connected to the turntable 54, thereby driving the rotating end of the turntable 54 to rotate, which in turn drives the clamping assembly 55 to rotate around the axis of the turntable 54 to facilitate the adjustment of the clamping angle of the clamping claw 551.
[0036] Please see Figure 4 and Figure 5 In this embodiment, the detection module 1 includes a U-shaped shield 110. The conveying device 3 can drive the dust cover 2 to be tested into and out of the U-shaped shield 110. A detection camera 120 is installed inside the U-shaped shield 110. The air blowing component 6 is set inside the U-shaped shield 110, so that the conveying device 3 can carry the dust cover 2 to be tested along a preset trajectory so that it can smoothly enter the detection module 1. The detection camera 120 takes pictures of the dust cover 2 to be tested and performs image processing and defect analysis based on the results of the picture detection to distinguish between qualified products and defective products.
[0037] Please see Figure 2 and Figure 7In this embodiment, the suction assembly 4 includes a lifting telescopic component 41 disposed on the side of the dust cover 2 to be tested near the conveying device 3, and an installation cylinder 42 fixedly connected to the top of the telescopic end of the lifting telescopic component 41 and extending along the conveying direction perpendicular to the conveying device 3. This allows the installation cylinder 42 to rise and fall vertically, facilitating real-time adjustment of the height position of the installation cylinder 42 according to the height position of the dust cover 2 to be tested, ensuring a constant distance between the suction nozzle 43 and the surface of the dust cover 2 to be tested. Multiple suction nozzles 43 are arranged along the extending direction of the installation cylinder 42 and are evenly spaced and embedded. On the mounting cylinder 42, a continuous negative pressure zone is formed on the adsorption surface of the mounting cylinder 42, and the adsorption force is evenly distributed. When the conveying end of the lifting telescopic component 41 descends and drives the mounting cylinder 42 to descend to a constant distance from the surface of the dust cover 2 to be tested, multiple suction nozzles 43 adsorb and collect the dust attached to the surface of the dust cover 2 to be tested, cleaning and collecting some of the attached dust and other impurities. When the conveying end of the lifting telescopic component 41 rises and drives the mounting cylinder 42 to rise and reset, multiple suction nozzles 43 effectively absorb the dust and other impurities that drift out from the detection module 1.
[0038] Please see Figure 4 and Figure 8 In a preferred embodiment, the blowing assembly 6 includes a mounting plate 61 installed in a location away from the detection module 1. Multiple blowing nozzles 62 are arranged along the length of the mounting plate 61 and are evenly spaced on the mounting plate 61. After the gas is ejected from the outlet of the multiple blowing nozzles 62, it blows onto the surface of the dust cover 2 to be tested, thereby achieving a better cleaning effect and a faster cleaning speed. This effectively improves the detection accuracy and efficiency of the detection module 1, causing dust and other impurities on the surface of the dust cover 2 to drift outwards from the detection module 1 with the blown airflow. Consequently, the dust and other impurities drift towards the suction end of the suction assembly 4 and are then collected and stored by the suction assembly 4.
[0039] Please see Figure 9 In some related embodiments, the blowing assembly 6 includes a mounting plate 61 installed away from the detection module 1, and a single blowing nozzle 62 is installed on the mounting plate 61 with the air outlet of the blowing nozzle 62 facing the surface of the dust cover 2 to be tested. After the gas is sprayed out at the air outlet of the single blowing nozzle 62, it blows the surface of the dust cover 2 to be tested, causing dust and other impurities on the surface of the dust cover 2 to drift outward from the detection module 1 with the blown airflow, and then causing the dust and other impurities to drift towards the air intake end of the suction assembly 4, and then be collected and stored by the suction assembly 4.
[0040] Please see Figure 3 and Figure 5In this embodiment, the conveying device 3 is a tank chain conveying device 3. The reciprocating linear motion of the conveying device 3 is converted into the continuous rolling of the chain links by adopting a tank chain-like hinge structure. This avoids the sliding friction caused by traditional belt or gear transmission, effectively improves the transmission efficiency, and at the same time protects the internal cables and pipes of the conveying device 3 from getting tangled during the movement of the conveying device 3.
[0041] Please see Figure 3 and Figure 5 In this embodiment, the detection device for the car dust cover further includes: a transfer platform 7 for positioning the dust cover 2 to be detected and adjusting the angle of the dust cover 2 to be detected; a first loading robot 8 for clamping the dust cover 2 to be detected onto the transfer platform 7; and a second loading robot 9 for clamping the dust cover 2 to be detected on the transfer platform 7 onto the flipping mechanism 5. The first loading robot 8 picks up the dust cover 2 to be detected and places it on the transfer platform 7 to achieve automated loading. The transfer platform 7 temporarily stores the dust cover 2 to be detected and adjusts the angle of the dust cover 2 to be detected to bridge the gap between loading and conveying. Then, the second loading robot 9 transfers the dust cover 2 to be detected on the transfer platform 7 to the flipping mechanism 5 on the conveying device 3. The flipping mechanism 5 clamps and fixes the dust cover 2 to be detected, and then the conveying device 3 carries the dust cover 2 to be detected along a preset trajectory into the detection module 1.
[0042] The implementation principle of Embodiment 1 is as follows: The conveying device 3 carries the dust cover 2 to be tested along a preset trajectory to the testing module 1. The suction component 4 is located beside the conveying device 3 and in front of the testing module 1. The blowing component 6 is located on the testing module 1 near the input port. Before the dust cover 2 to be tested enters the testing module 1, the suction component 4 first adsorbs and collects the dust attached to the surface of the dust cover 2, cleaning and collecting some of the attached dust and other impurities. Then, the conveying device 3 continues to move along the preset trajectory, moving the dust cover 2 to be tested into the testing module 1 for testing. The flipping mechanism 5 drives the dust cover 2 to be tested... The dust cover 2 flips up, down, left, and right, and the blowing component 6 starts simultaneously to blow on the surface of the dust cover 2 to be tested, separating and cleaning the remaining firmly attached dust and other impurities on the surface of the dust cover 2 to be tested, and causing the dust and other impurities to drift outward with the blown airflow towards the outside of the detection module 1, so that the detection module 1 can analyze the appearance defects of the dust cover 2 to be tested, such as whether there are burrs, white spots, etc., and avoid false detection or missed detection caused by surface contamination of the dust cover 2 to be tested. Then, based on the test results, qualified products and defective products are sorted. At the same time, the suction component 4 starts simultaneously to collect the dust and other impurities that are flipped and shaken off by the flipping mechanism 5 and blown off by the blowing component 6.
[0043] Example 2 Please see Figures 1-8 Embodiment 2 of this application discloses a method for testing automotive dust covers, including the following steps: S11: The dust cover 2 to be tested is held by the flipping mechanism 5.
[0044] Specifically, by activating the second drive member 552 on the flipping mechanism 5, the transmission screw 553 is driven to rotate, and then the transmission screw 553 pushes the movable claw 5512 to move towards the fixed claw 5511. The movable claw 5512 and the fixed claw 5511 clamp the dust cover 2 to be tested.
[0045] S12: The conveying device 3 drives the flipping mechanism 5 and the dust cover 2 to be tested through the suction component 4, and the suction component 4 performs preliminary dust suction on the dust cover 2 to be tested.
[0046] Specifically, after clamping, the conveying device 3 carries the dust cover 2 to be tested along the preset trajectory to the suction component 4 through the flipping mechanism 5. The lifting telescopic component 41 drives the mounting cylinder 42 to descend vertically. Multiple suction nozzles 43 are activated to form a continuous negative pressure zone on the adsorption surface of the mounting cylinder 42, adsorbing and collecting the dust attached to the surface of the dust cover 2 to be tested, cleaning and collecting some of the attached dust and other impurities. After the dust suction is completed, the lifting telescopic component 41 drives the mounting cylinder 42 to rise and reset.
[0047] S13: The conveying device 3 drives the flipping mechanism 5 into the detection module 1, and the flipping mechanism 5 drives the dust cover 2 to be tested to rotate. At the same time, the detection module 1 detects the surface of the dust cover 2 to be tested, and the blowing assembly 6 blows the surface of the dust cover 2 to be tested. The blowing airflow flows to the outside of the detection module 1 and is sucked up by the suction assembly 4.
[0048] Specifically, after the dust collection is completed, the conveying device 3 continues to move along the preset trajectory, transferring the dust cover 2 to be tested into the testing module 1. The flipping mechanism 5 drives the dust cover 2 to be tested to flip up, down, left, and right. The testing camera 120 takes pictures of the five surfaces of the dust cover 2 to be tested. Based on the results of the picture testing, image processing and defect analysis are performed to distinguish between qualified products and defective products. The blowing component 6 is activated simultaneously to blow on the surface of the dust cover 2 to be tested, separating and cleaning the remaining dust attached to the surface of the dust cover 2. The dust and other impurities that fall off are carried away by the airflow towards the outside of the testing module 1. The suction component 4, which is activated simultaneously, sucks up and collects the dust and other impurities that are flipped and shaken off by the flipping mechanism 5 and blown off by the blowing component 6.

[0050] Specifically, the loading robotic arm 10 picks up the dust cover 2 to be tested and transfers it to the flipping mechanism 5 on the conveying device 3. The flipping mechanism 5 clamps and fixes the dust cover 2 to be tested.
[0051] Step S13 is followed by: S14: Provide a sorting robot arm 11. Use the sorting robot arm 11 to sort and unload materials. The sorting robot arm 11 performs actions according to the detection results, sorting and transferring qualified products to the packaging platform or placing them in the turnover device, and sorting and transferring defective products to the rework platform or placing them in the storage device.
[0052] Specifically, after the inspection is completed, the inspection camera 120 transmits the inspection results to the sorting robot arm 11. The sorting robot arm 11 performs actions to sort qualified products and defective products according to the inspection results. Qualified products are sorted and transferred to the packaging platform or placed in the turnover device, while defective products are sorted and transferred to the rework platform or placed in the storage device.
[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
