[0002] For aluminum alloy workpieces that need to be equipped with sealing rings around them, the sealing rings are usually installed in the grooves around the center axis hole to prevent liquid or gas leakage, and also to prevent dust, dirt and other impurities from entering the workpiece. The selection and installation requirements of the sealing rings depend on the specific application environment and conditions. Common sealing ring materials include rubber (such as NBR, EPDM), silicone, fluororubber (FKM), etc. These materials have different temperature resistance, wear resistance and chemical corrosion resistance, and are suitable for different working environments.

[0003] When installing the seal, it is necessary to ensure that the seal is fully embedded in the predetermined groove and is not twisted or damaged. Before installation, the mounting surface of the aluminum alloy workpiece is usually cleaned to remove any contaminants that may affect the sealing performance. In some cases, special tools are required to assist installation to avoid damaging the seal.

[0004] After the installation of the existing aluminum alloy workpiece sealing rings is completed, the installation status of the sealing rings is mainly identified manually and manually classified, which has a high work intensity and reduces production efficiency. Summary of the invention

[0032] First embodiment

[0033] See also Figure 1 to Figure 6 The present invention provides a visual inspection device for the installation of sealing rings of aluminum alloy workpieces, comprising a base 101, a support frame 102, a conveyor line 103, a detection component 104 and a classification component 105, wherein the support frame 102 is fixedly connected to the base 101 and is located on the top of the base 101, the conveyor line 103 is rotatably arranged on one side of the support frame 102, and the detection component 104 is arranged on one side of the conveyor line 103 for taking pictures to monitor the installation status of the sealing ring; the classification component 105 comprises a driver 106, a lifter 107, a toggle rod 108, a first auxiliary line 109 and a second auxiliary line 110, wherein the first auxiliary line 109 and the second auxiliary line 110 are arranged on both sides of the conveyor line 103, the driver 106 is slidably arranged above the conveyor line 103, the lifter 107 is connected to the output end of the driver 106, and the toggle rod 108 is connected to the output end of the lifter 107.

[0034] In this embodiment, the base 101 serves as the foundation of the entire detection device. It not only provides a stable support function, but also ensures the precise installation position of each subsequent component. The support frame 102 is installed on the top of the base 101 by a fixed connection with the base 101. The design of the support frame 102 must not only take into account the structural strength, but also ensure that it can provide a reliable support platform for other components. The conveyor line 103 is a key part of the movement of the workpiece during the entire detection process. It is rotatably arranged on one side of the support frame 102, and can smoothly convey the aluminum alloy workpiece to be detected to the detection position.

[0035] The detection component 104 is arranged on one side of the conveyor line 103. Its main task is to take pictures of the aluminum alloy workpiece passing through the conveyor line 103 and judge whether the sealing ring is correctly installed by image analysis. Installation status The package is installed normally, not installed, and installed too much.

[0036] The classification component 105 includes a driver 106, a lifter 107, a toggle rod 108 and two auxiliary lines (a first auxiliary line 109 and a second auxiliary line 110). The two auxiliary lines are respectively arranged on both sides of the conveyor line 103, and the workpieces with or without sealing rings installed can be sent out respectively. The driver 106 can slide along the top of the conveyor line 103 to provide power support for the classification action. The lifter 107 is connected to the output end of the driver 106 and is responsible for the up and down movement. The toggle rod 108 is directly connected to the output end of the lifter 107. Its function is to pull out the unqualified workpiece from the normal production line when detecting it, so as to realize the automatic classification of qualified products and defective products. Specifically, the workpiece identified as being normally installed by the detection component 104 is conveyed along the conveyor line 103, and when it is detected that it is not installed or is over-installed, the lifter 107 is started to descend, so that the toggle rod 108 is inserted into the through hole of the workpiece, and then the driver 106 is moved left and right to send the workpiece to two auxiliary lines respectively for reinstallation processing, thereby improving production efficiency and reducing errors caused by manual inspection.

[0037] The conveying line 103 has a plurality of convex strips 111 , and the convex strips 111 are distributed on the conveying line 103 .

[0038] These convex strips 111 are evenly distributed on the entire surface of the conveying line 103, and play a role in preventing the workpiece from sliding or deflecting during the conveying process, thereby ensuring that the workpiece can smoothly reach the designated detection position.

[0039] The support frame 102 is further provided with two limit plates 112 , and the two limit plates 112 are rotatably provided on both sides of the conveying line 103 .

[0040] In order to further improve the working stability of the conveyor line 103, two limit plates 112 are specially provided, and the two limit plates 112 are rotatably arranged on both sides of the conveyor line 103. The main function of the limit plates 112 is to limit the lateral movement range of the workpiece to avoid the problem of inaccurate positioning caused by the vibration of the conveyor line 103 or the size difference of the workpiece.

[0041] The limiting plate 112 includes a plate body 113, a rotating rod 114 and a locking ring 115. The rotating rod 114 is rotatably set on the support frame 102. The plate body 113 is fixedly connected to the rotating rod 114 and is located on one side of the rotating rod 114. The locking ring 115 is set on the rotating rod 114 for locking the position of the rotating rod 114.

[0042] Each limiting plate 112 includes a plate body 113, a rotating rod 114 and a locking ring 115. The rotating rod 114 is designed to rotate freely on the support frame 102, so that the plate body 113 can be adjusted according to the requirements of workpieces of different sizes. The plate body 113 is fixed together with the rotating rod 114 and is located on one side of the rotating rod 114 to ensure that it remains stable after the position is adjusted. The locking ring 115 is installed on the rotating rod 114. When the position of the limiting plate 112 is adjusted, the position of the rotating rod 114 can be fixed by the locking ring 115 to prevent it from changing at will during operation.

[0043] The detection component 104 includes a protective shell 116 , a camera 117 and a detector. The protective shell 116 is disposed on the top of the conveyor line 103 , the camera 117 is disposed in the protective shell 116 , and the detector is connected to the camera 117 .

[0044] The protective shell 116 is installed directly above the conveyor line 103, which not only provides physical protection for the internal components, but also plays a role in shielding external light interference. The camera 117 is placed inside the protective shell 116 and is specifically used to capture the workpiece image. The detector is connected to the camera 117 and is responsible for processing and analyzing the image information.

[0045] The detector includes an image acquisition module 119, an image extraction module 120, a recognition module 121 and a control module 122. The image acquisition module 119 is used to acquire the image captured by the camera 117, and the image extraction module 120 is used to extract the workpiece features in the image; the recognition module 121 is used to classify the installation status of the sealing ring based on the workpiece features, and the installation status includes normal installation, non-installation and multiple installation; the control module 122 is used to control the toggle lever 108 based on the installation status.

[0046] The image acquisition module 119 is mainly used to receive the image data captured by the camera 117. When the workpiece is transported to the inspection area, the camera 117 will take pictures of the workpiece, and the image acquisition module 119 will then receive these images and convert them into digital signals for subsequent processing. The design of this part needs to ensure high-quality image input, because the quality of the image directly affects the subsequent processing effect.

[0047] The image extraction module 120 is responsible for extracting key feature information from the acquired image. These features may include but are not limited to the shape, color, texture, and position of the seal ring of the workpiece. The image extraction module 120 uses image processing technology, such as edge detection, feature point extraction, and other algorithms to convert the image into data for analysis.

[0048] The recognition module 121 is the core of the entire system. It uses a pre-trained model (such as a machine learning model or a deep learning model) to determine the installation status of the seal ring based on the feature data provided by the image extraction module 120. The installation status is divided into three types: normal installation, non-installation, and multiple installation. This means that even if there is a slight deviation in the seal ring, the recognition module 121 can accurately identify it and classify it. This high-precision recognition capability relies on a large amount of training data and advanced algorithm support.

[0049] The function of the control module 122 is to determine the next operation according to the classification result of the identification module 121. For example, if it is identified that the sealing ring is not installed properly (i.e., not installed or installed too much), the control module 122 will send a command to the classification component 105, and through the linkage of the driver 106 and the lifter 107, the toggle rod 108 will be controlled to separate the unqualified workpiece from the normal production line and move it to the auxiliary line for subsequent processing. On the contrary, if the sealing ring is installed normally, the workpiece is allowed to continue to move along the original conveyor line 103.

[0050] The detection component 104 further includes a fill light 123 , which is disposed in the protective shell 116 and is used to illuminate the workpiece to be photographed.

[0051] These fill lights 123 are also disposed in the protective shell 116 , and their function is to provide sufficient lighting for the workpiece during the shooting process, to ensure image clarity, and thus to improve the accuracy and reliability of detection.

[0052] The driver 106 includes a two-way driving cylinder 124 and a mounting block 125, and the mounting block 125 is connected to the two-way driving cylinder 124. The lifter 107 includes a lifting cylinder 130, a lifting rod 131 and a first spring 132. The lifting cylinder 130 is arranged on the mounting block 125, and the lifting rod 131 is connected to the output end of the lifting cylinder 130. The first spring 132 is arranged between the lifting cylinder 130 and the lifting rod 131.

[0053] The driver 106 is designed to realize the horizontal movement of the sorting assembly 105, and mainly includes two parts: a bidirectional driving cylinder 124 and a mounting block 125. The mounting block 125 is tightly connected to the bidirectional driving cylinder 124, and the bidirectional driving cylinder 124 is responsible for providing horizontal power, so that the entire sorting assembly 105 can move left and right along a specific track above the conveyor line 103.

[0054] The lifter 107 is the part responsible for vertical movement in the classification component 105, and is composed of a lift cylinder 130, a lift rod 131 and a first spring 132. The lift cylinder 130 is mounted on the above-mentioned mounting block 125, and is connected to the lift rod 131 through its output end, thereby realizing the up and down movement function of the lift rod 131. The first spring 132 is arranged between the lift cylinder 130 and the lift rod 131 to buffer the impact force during the lifting process and ensure the smoothness of the lifting action.

[0055] The toggle rod 108 includes a sliding block 126, a support rod 127, a rod body 128 and a return spring 129. The support rod 127 is fixed to the lifting rod 131, the sliding block 126 is slidably set on the support rod 127, the rod body 128 is fixed under the sliding block 126, and the return spring 129 is set between the sliding block 126 and the support rod 127.

[0056] The toggle rod 108 is the part of the classification component 105 that is most directly involved in the classification of workpieces. It includes several major components such as a sliding block 126, a support rod 127, a rod body 128 and a reset spring 129. One end of the support rod 127 is fixed to the lifting rod 131, and the other end is used to support the sliding block 126. The sliding block 126 can slide along the support rod 127, so that the workpiece can move normally along the conveyor line 103 when toggled on the conveyor line 103 without stopping and affecting the subsequent workpieces, thereby quickly responding and executing the action. The rod body 128 is fixed below the sliding block 126, directly contacting and acting on the workpiece. The reset spring 129 is arranged between the sliding block 126 and the support rod 127. When the toggle rod 108 completes an action, the reset spring 129 can help the sliding block 126 quickly return to the initial position to prepare for the next operation.

[0057] The combined design of the driver 106 and the lifter 107 ensures that the sorting component 105 can accurately move in the horizontal and vertical directions, and the design of the toggle rod 108 ensures that unqualified workpieces can be promptly and accurately removed from the production line when detected, thereby realizing the functions of automatic detection and sorting. Such a design not only improves production efficiency, but also greatly reduces errors caused by manual operation.

[0058] Second embodiment

[0059] See also Figure 7 The present invention also provides a method for visually inspecting the installation of a sealing ring of an aluminum alloy workpiece, comprising:

[0060] S201 places the workpiece on the conveyor line 103 for conveying;

[0061] The operator or the automation device places the aluminum alloy workpiece to be inspected at the starting position of the conveyor line 103. The convex strips 111 on the conveyor line 103 ensure that the workpiece can move smoothly during the conveying process and prevent the workpiece from being offset due to vibration or irregular shape.

[0062] S202 The workpiece is moved to one side of the detection component 104, and the detection component 104 takes a photo of the workpiece to distinguish the installation conditions of the workpiece, which include normal installation, non-installation, and over-installation;

[0063] As the conveyor line 103 operates, the workpiece is transferred to the location of the detection component 104. At this time, the camera 117 in the detection component 104 will take a picture of the workpiece and obtain a picture of the workpiece. The built-in fill light 123 of the camera 117 will light up at the moment of shooting, providing sufficient lighting for the workpiece and ensuring the clarity of the photo. Subsequently, the image acquisition module 119 in the detector reads the image taken by the camera 117, and analyzes the workpiece features in the image through the image extraction module 120. The recognition module 121 determines the installation status of the sealing ring based on these features, including three states: normal installation, non-installation, and multiple installation.

[0064] S203 drives the lifter 107 to move downward according to the installation situation, so that the toggle rod 108 is inserted into the workpiece;

[0065] Once the recognition module 121 determines the installation status of the workpiece, the control module 122 will issue instructions based on the detection results. If the installation status of the workpiece is abnormal (i.e., not installed or installed too much), the control module 122 will drive the lifter 107 to move downward, so that the toggle rod 108 descends and inserts into the workpiece, preparing to remove the workpiece from the normal conveying path.

[0066] S204 then drives the driver 106 to drive the toggle rod 108 to move the workpiece to the first auxiliary line 109 or the second auxiliary line 110 according to the installation situation.

[0067] After the toggle rod 108 is inserted into the workpiece, the driver 106 will drive the toggle rod 108 and the workpiece thereon to move to one side according to the instruction of the control module 122, and the abnormal workpiece will be put into the first auxiliary line 109 or the second auxiliary line 110. In this way, unqualified workpieces will be automatically sorted out, while qualified workpieces will continue to move along the original conveying line 103 and enter the next process.

[0068] This detection method not only improves the efficiency and accuracy of detection, but also reduces labor costs and enhances quality control capabilities during the production process through automation.

[0069] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
