Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, and more specifically, to a glass primer detection device. Background Technology

[0002] In automobile production, a glass primer needs to be applied to the installation location before installing the body glass. The main functions of the glass primer include enhancing the adhesion of the glass adhesive, preventing aging, providing anti-corrosion protection, and improving durability. The primer liquid contains highly hazardous chemicals such as xylene, ethyl acetate, and acetone. Long-term human exposure can lead to health hazards such as nervous disorders, asthma, and cancer. In current production, many factories use robotic arms for automated primer application, while inspection cameras simultaneously detect the primer quality. However, due to the large curvature of the glass surface, in some cases, the robotic arm needs to perform 360-degree rotation for coating. When the robotic arm is turning, the inspection camera deviates from the primer application trajectory, making it impossible to reliably detect the primer application position. The inspection results are frequently unqualified, affecting production efficiency. Consequently, manual inspection of primer quality is required in the long term, which affects the health of workers. In addition, the glass primer process requires cleaning before applying the primer. Current technology requires switching between different robotic arms or different tool ends of the robotic arm to perform cleaning and primer application separately, which increases equipment costs and reduces production efficiency. Utility Model Content

[0003] To overcome the shortcomings of the prior art in glass primer coating process, which requires the use of different robotic arms or tool ends for cleaning and primer coating, resulting in high equipment costs, this utility model provides a glass primer coating inspection device that eliminates the need to switch between robotic arms or tool ends during cleaning and primer coating, thereby reducing equipment costs and improving production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a glass primer detection device, comprising: a mounting frame, a primer component and a cleaning component respectively mounted on both sides of the mounting frame, and a visual detection component connected to the mounting frame. The visual detection component is located on one side of the primer component and is used to detect the coating effect of the primer component. The cleaning component is telescopically mounted on the mounting frame and is inclined toward the primer component.

[0005] The mounting bracket is used to connect to external equipment. The primer and cleaning components are mounted on opposite sides of the bracket. The cleaning component is telescopically mounted on the bracket. When the primer is working, the cleaning component retracts to avoid interfering with the work. The telescopic structure can use a cylinder or linear motor, etc. The cleaning component is tilted towards the primer, making the overall structure more compact and facilitating component switching. At the same time, a vision inspection component is also set next to the primer. The detection end of the vision inspection component is set towards the working end of the primer. When the primer is being applied, the vision inspection component detects the brushing trajectory in real time, thereby checking the brushing effect.

[0006] With the above configuration, this testing device can simultaneously perform cleaning, primer coating, and inspection functions. In use, the testing device is mounted on an external device via a mounting bracket. The primer coating component and the cleaning component are respectively connected to the external primer coating liquid and cleaning liquid via pipelines. The working angle of the testing device is adjusted by rotating the external device, thereby achieving the switching between cleaning and primer coating functions. When the primer coating component is working, the vision inspection component performs real-time inspection, improving work efficiency while ensuring coating quality. Furthermore, it eliminates the need to switch to other working ends or other robotic arms, thus reducing equipment costs and production costs.

[0007] Preferably, it further includes a floating component connected to the mounting bracket, the floating component including a first elastic reset member with both ends abutting against the mounting bracket and the primer component respectively, and a second elastic reset member with both ends abutting against the mounting bracket and the cleaning component respectively; both the floating component and the cleaning component are slidably connected to the mounting bracket.

[0008] The floating components allow the primer and cleaning components to float relative to the mounting bracket. The primer component slides on the mounting bracket, allowing the entire primer component to move relative to the bracket. A first elastic reset component is then added, with its two ends abutting against the primer component and the mounting bracket respectively. Through elasticity, the primer component is reset, allowing it to float relative to the mounting bracket in a resettable manner. This prevents interference between the primer component and the exterior vehicle body and allows the working end of the primer component to better conform to the exterior vehicle body, resulting in a better primer coating effect. Similarly, the cleaning component is designed with a similar structure and can also float relative to the mounting bracket in a resettable manner, improving the cleaning effect. Springs are preferred for both the first and second elastic reset components.

[0009] Preferably, the floating assembly further includes a cylindrical member connected to the mounting bracket and a limiting ring connected to the cylindrical member. The primer assembly includes a primer liquid tube slidably connected to the cylindrical member, a primer brush head and a primer connector respectively connected to the primer liquid tube. The first elastic reset member is disposed inside the cylindrical member, and both ends of the first elastic reset member abut against the cylindrical member and the primer liquid tube respectively. The limiting ring is fitted on the primer liquid tube and is used to prevent the primer liquid tube from detaching from the cylindrical member.

[0010] The primer tube passes through and slides on the cylindrical component. A retaining ring secures the primer tube to the cylindrical component, restricting its movement and preventing it from detaching. A first elastic reset member is located inside the cylindrical component and fitted onto the primer tube, with its two ends abutting against the inner wall of the cylindrical component and the flange of the primer tube, respectively. At this point, the cylindrical component and the retaining ring are fixed relative to the mounting bracket, while the primer tube can move relative to the cylindrical component and the retaining ring. The primer brush head and primer connector are fixedly mounted on the primer tube. When the primer tube moves, it compresses the first elastic reset member, thus achieving a repositionable floating of the primer assembly relative to the mounting bracket. The primer enters through the primer connector, flows through the primer tube, adheres to the primer brush head, and then begins its application.

[0011] Preferably, it also includes a clearance bracket installed on one side of the mounting frame and a limiting block installed on the clearance bracket. The primer connector is an elbow structure and is connected to the end of the primer liquid pipe. The clearance bracket is provided with a clearance part. The primer connector is located at the clearance part. The top side of the primer liquid pipe is provided with a limiting groove. When the primer liquid pipe moves to a set position, the limiting groove abuts against the limiting block.

[0012] The primer connector adopts an elbow structure and is located at the end of the primer liquid pipe to avoid placing the primer connector on the side, thus maintaining the integrity of the cylindrical structure and providing more protection for the primer liquid pipe and the first elastic reset component. The clearance bracket is used to provide clearance for the movement of the primer connector. A limit block is set to further limit the movement of the primer liquid pipe. When the primer liquid pipe is pushed to the set position, the limit block abuts against the limit groove to prevent the primer liquid pipe from moving further. Furthermore, the limit block and the clearance bracket are detachably connected for easy adjustment.

[0013] Preferably, the primer brush head is snapped into the primer liquid tube, the bottom side of the primer liquid tube is provided with a plurality of alignment grooves, and the top of the primer brush head is provided with a plurality of alignment blocks that cooperate with the alignment grooves.

[0014] The primer brush head snaps into the primer liquid tube, facilitating the installation and replacement of the primer connector. At the same time, an alignment groove is set at the bottom of the primer liquid tube to allow the primer brush head to snap into place at different angles.

[0015] Preferably, it further includes a cylinder mounted on the mounting bracket, a first connecting plate mounted on the telescopic end of the cylinder, the cleaning component being slidably connected to the first connecting plate, and the two ends of the second elastic reset member abutting against the first connecting plate and the cleaning component, respectively.

[0016] A cylinder is used to enable the retractable function of the cleaning component.

[0017] Preferably, the visual inspection component includes a mounting box fitted onto the cylindrical component and at least two visual inspection cameras mounted inside the mounting box. The detection ends of the visual inspection cameras extend outside the mounting box and are positioned towards the primer brush head. The visual inspection cameras are arranged circumferentially along the cylindrical component and are distributed at an angle of 110°-130°. The visual inspection cameras cooperate with each other to form binocular visual inspection or multi-view visual inspection.

[0018] A mounting box is used to protect the vision inspection camera. The main body of the vision inspection camera is installed inside the mounting box, with the detection end extending out of the mounting box and facing the primer brush head for inspection. At least two vision inspection cameras are set up to cover two or more sides of the primer brush head. The effect of the primer can be detected when the primer brush head rotates or turns, thus adapting to changes in the posture of the primer at glass corners. This avoids the inability to identify the brushing trajectory due to field of view deviation, avoids affecting the inspection structure or missing inspections, and further avoids manual re-inspection, ensuring the health of workers. Existing vision cameras can be used for the vision inspection camera. The setting of two or more vision inspection cameras can form a binocular or multi-view vision inspection.

[0019] Preferably, the visual inspection component further includes a waterproof cover plate disposed on the top of the mounting box, and an auxiliary light source is provided on the detection end of the visual inspection camera.

[0020] A waterproof cover is used to cover the top of the mounting box to prevent primer from dripping onto the mounting box when disconnecting the external pipeline of the primer interface, thereby minimizing the adhesion of primer to the vision inspection camera; an auxiliary light source is set to minimize the impact of changes in ambient light on the inspection. The vision inspection camera can be a vision camera with an auxiliary light source, or a light source can be set around the lens of the vision camera.

[0021] Preferably, the cleaning assembly includes a plurality of sliding rods slidably connected to the first connecting plate, a second connecting plate connected to the sliding rods, a cleaning fluid tube connected to the second connecting plate, a cleaning connector and a cleaning brush head respectively installed on the cleaning fluid tube, and the two ends of the second elastic reset member abutting against the first connecting plate and the second connecting plate respectively.

[0022] The second elastic reset component is respectively fitted onto the sliding rod, and its two ends abut against the first connecting plate and the second connecting plate respectively, thereby realizing the resettable floating of the cleaning component. The cleaning fluid enters from the cleaning connector, flows through the cleaning fluid tube and adheres to the cleaning brush head, and then works.

[0023] Preferably, the device also includes two pneumatic valves mounted on the mounting bracket, and the primer connector and the cleaning connector are both connected to the pneumatic valves via hoses.

[0024] Two pneumatic valves are used to control the flow of primer and cleaning fluid respectively. Compared with solenoid valves, pneumatic valves are less expensive.

[0025] Compared with the prior art, the beneficial effects of this utility model are: This inspection device can simultaneously perform cleaning, primer coating, and inspection functions. In use, the device is mounted on an external device using a mounting bracket. The primer coating component and the cleaning component are connected to the external primer and cleaning solutions via pipelines, respectively. The working angle of the inspection device is adjusted by rotating the external device, thereby switching between cleaning and primer coating functions. While the primer coating component is working, the vision inspection component performs real-time inspection, improving work efficiency while ensuring coating quality. Furthermore, it eliminates the need to switch to other working ends or other robotic arms, thus reducing equipment costs and production costs. Attached Figure Description

The vision inspection component is located on one side of the primer component 2 and is used to inspect the coating effect of the primer component 2. The cleaning component 3 is telescopically mounted on the mounting frame 1 and is inclined toward the primer component 2.

[0031] Mounting bracket 1 is used to connect to external equipment. Primer component 2 and cleaning component 3 are respectively mounted on both sides of mounting bracket 1. The cleaning component 3 is telescopically mounted on mounting bracket 1. When primer component 2 is working, cleaning component 3 retracts to avoid interfering with the work. The telescopic structure can be a cylinder 6 or a linear motor, etc. The cleaning component 3 is tilted towards primer component 2, making the overall structure more compact and facilitating component switching. At the same time, a vision inspection component is also set next to primer component 2. The detection end of the vision inspection component is set towards the working end of primer component 2. When primer component 2 is applying the primer, the vision inspection component detects the brushing trajectory in real time and checks the brushing effect.

[0032] The beneficial effects of this embodiment are as follows: Through the above-described configuration, the detection device can simultaneously perform cleaning, primer coating, and inspection functions. In use, the detection device is mounted on an external device via the mounting bracket 1. Simultaneously, the primer coating component 2 and the cleaning component 3 are connected to the external primer coating liquid and cleaning liquid via pipelines, respectively.

Furthermore, there is no need to switch to other working ends or other robotic arms, which also reduces equipment costs and production costs.

[0033] Example 2 This embodiment further defines the features of Embodiment 1, and its difference from Embodiment 1 lies in: like Figure 1 , Figure 3 and Figure 5 As shown, it also includes a floating assembly connected to the mounting bracket 1.

The limiting ring 9 is fitted onto the primer liquid tube 10 and is used to prevent the primer liquid tube 10 from detaching from the cylindrical member 8. Figure 4 As shown, it also includes a clearance bracket 13 installed on one side of the mounting frame 1, and a limiting block 14 installed on the clearance bracket 13. The primer connector 12 is an elbow structure and is connected to the end of the primer liquid pipe 10. The clearance bracket 13 is provided with a clearance part, and the primer connector 12 is located at the clearance part. A limiting groove 1001 is provided on the top side of the primer liquid pipe 10. When the primer liquid pipe 10 moves to the set position, the limiting groove 1001 abuts against the limiting block 14.

The bottom side of the primer liquid tube 10 has multiple alignment grooves 1002, and the top of the primer brush head 11 has multiple alignment blocks 1101 that mate with the alignment grooves 1002.

[0034] The floating components allow the primer component 2 and the cleaning component 3 to float relative to the mounting bracket 1. The primer component 2 is slidably mounted on the mounting bracket 1, allowing the entire primer component 2 to move relative to the mounting bracket 1. A first elastic reset component 4 is then provided, with its two ends abutting against the primer component 2 and the mounting bracket 1 respectively. This elasticity allows the primer component 2 to be reset, enabling it to float relative to the mounting bracket 1 in a resettable manner. This prevents interference between the primer component 2 and the external vehicle body, and also allows the working end of the primer component 2 to better conform to the external vehicle body, resulting in a better primer coating effect. Similarly, the cleaning component 3 is also designed with a similar structure, allowing it to float relative to the mounting bracket 1 in a resettable manner, improving the cleaning effect. Springs are preferred for both the first elastic reset component 4 and the second elastic reset component 7. The primer tube 10 passes through the cylindrical member 8 and is slidably connected to it. A retaining ring 9 is used to mount the primer tube 10 onto the cylindrical member 8, restricting its movement and preventing it from detaching from the cylindrical member 8. A first elastic reset member 4 is disposed inside the cylindrical member and fitted onto the primer tube 10, with its two ends abutting against the inner wall of the cylindrical member 8 and the flange of the primer tube 10, respectively.

The primer brush head 11 and the primer connector 12 are fixedly mounted on the primer tube 10. When the primer tube 10 moves, it compresses the first elastic reset member 4, thereby achieving a repositionable floating of the primer assembly 2 relative to the mounting member. The primer enters through the primer connector 12, flows through the primer tube 10, adheres to the primer brush head 11, and then begins operation. The primer connector 12 adopts an elbow structure and is located at the end of the primer liquid pipe 10 to avoid placing the primer connector 12 on the side, thus maintaining the integrity of the cylindrical component 8 and providing more protection for the primer liquid pipe 10 and the first elastic reset component 4.

The detection ends of the vision inspection cameras 16 extend beyond the mounting box 15 and are positioned towards the primer brush head 11. The vision inspection cameras 16 are arranged circumferentially along the cylindrical component 8, with a distribution angle of 110°-130°. The vision inspection cameras 16 cooperate to form binocular or multi-view vision inspection. The vision inspection assembly also includes a waterproof cover plate 17 disposed on the top of the mounting box 15, and auxiliary light sources are provided on the detection ends of the vision inspection cameras 16.

The detection end of the vision inspection camera 16 faces the primer brush head 11 for inspection. At least two vision inspection cameras 16 are set to cover two or more sides of the primer brush head 11. The effect of the primer can be detected when the primer brush head 11 rotates or turns, thereby adapting to the change of the primer posture at glass corners, avoiding the inability to identify the brushing trajectory due to field of view deviation, avoiding affecting the inspection structure or missing inspection, and further avoiding manual re-inspection, ensuring the health of workers. The vision inspection camera 16 can be an existing vision camera. The setting of two or more vision inspection cameras 16 can form a binocular or multi-view vision inspection. A waterproof cover 17 is used to cover the top of the mounting box 15 to prevent primer from dripping onto the mounting box 15 when the external pipeline of the primer interface is disconnected, thereby minimizing the adhesion of primer to the vision inspection camera 16. An auxiliary light source is provided to minimize the impact of ambient light changes on the inspection. The vision inspection camera 16 can be a vision camera with an auxiliary light source, or a light source can be set around the lens of the vision camera. The second elastic reset member 7 is respectively fitted onto the sliding rod 18, and its two ends abut against the first connecting plate 5 and the second connecting plate 19, thereby realizing the resettable floating of the cleaning component 3. The cleaning fluid enters from the cleaning connector 21, flows through the cleaning fluid pipe 20, and adheres to the cleaning brush head 22 before working. Two pneumatic valves 23 are provided to control the flow of primer and cleaning fluid respectively. Compared with solenoid valves, pneumatic valves 23 are less expensive.
