The box body 1 is provided with a top chamber 104, a spray chamber 102, and a placement chamber 103 from top to bottom. The bottom of the spray chamber 102 is embedded with a negative pressure adsorption seat 5. The servo control mechanism 2 is fixedly installed on the top of the negative pressure adsorption seat 5, and the top of the servo control mechanism 2 extends to the top chamber 104. The servo control mechanism 2 is composed of three groups of slide rod frames 201, three servo motors 202, three screw rods 203, three moving components 204, three linkage rods 205 and a moving seat 206. Among them, the three groups of slide rod frames 201 are equidistantly fixed on the top of the negative pressure adsorption seat 5. The top of the three sets of slide rod frames 201 are respectively fixedly installed with three servo motors 202, the output ends of the three servo motors 202 are respectively fixedly installed with three screw rods 203, the outer side threads of the three screw rods 203 are respectively installed with three moving components 204, the front of the three moving components 204 are respectively installed with three linkage rods 205 through shafts 2051, one end of the three linkage rods 205 are all installed with a moving seat 206 through the shaft 2051, the bottom of the moving seat 206 is rotatably installed with a penetrating angle adjustment mechanism 3, the bottom of the angle adjustment mechanism 3 is fixedly installed with a glue mixer 4, and the glue application position and angle of the glue mixer 4 are controlled by the cooperation of the servo control mechanism 2 and the angle adjustment mechanism 3; Among them, a three-dimensional scanning slide rod frame 201 is fixedly installed at the bottom of the moving seat 206. The three-dimensional scanning slide rod frame 201 consists of two slide rods and a top plate. The servo motor 202 is fixedly installed on the top plate. A three-dimensional scanner is fixedly installed at the bottom of the moving seat 206. The three-dimensional scanner adopts the Zeiss GOM Scan1 car light three-dimensional scanner. The car light is scanned and identified by the three-dimensional scanner, and its three-dimensional data is obtained and transmitted to the host 7 through wires. The host 7 generates corresponding glue coating parameters such as glue coating amount and position through the three-dimensional data; then, the servo control mechanism 2 drives, one of the servo motors 202 is powered on to drive the screw rod 203 at the output end to rotate, and the rotating screw rod 203 drives the threaded moving component 204 to move vertically. The vertically moving moving component 204 pulls the moving seat 206 to move through one of the linkage rods 205, and the other two linkage rods 205 follow the movement. The seat 206 moves to realize three-axis linkage, and the movable seat 206 drives the glue mixer 4 to adjust the position through the angle adjustment mechanism 3; at the same time, the three servo motors 202 run simultaneously, and the three servo motors 202 respectively drive the corresponding three screw rods 203 to rotate, and the three rotating screw rods 203 respectively drive the three moving components 204 to synchronously reciprocate vertically, and the three reciprocating vertically moving moving components 204 synchronously drive the moving seat 206 to move vertically through the three linkage rods 205, and the vertically moving moving seat 206 drives the glue mixer 4 to adjust the height through the angle adjustment mechanism 3; The angle adjustment mechanism 3 drives the glue mixer 4 to rotate and adjust the angle, so that the glue mixer 4 can be adjusted at multiple angles, which is convenient for flexible adjustment according to the complex curve of the headlight, and realizes accurate glue coating position and angle adjustment; At the same time, the position sensor 403 accurately tracks the gluing position of the anti-drip gluing head 402, and the camera 404 tracks every detail of the gluing process of the anti-drip gluing head 402, and transmits the detection signal to the host 7. The host 7 compares the standardized path and the uniformity of the gluing. When the abnormal situation of glue leakage and glue overflow occurs, the host 7 will automatically send a warning signal to the controller 101 to remind the operator to stop the current operation and make adjustments, which not only reduces the defective rate, but also shortens the production cycle of the headlight sealing, and greatly reduces the frequency of rework and secondary grinding, and finally realizes the automation and high precision of the headlight sealing process; The host 7 calculates the amount of glue to be applied according to the shape and structure of the headlight, and sets the metering of the metering pump 605 through the controller 101, and accurately applies a preset amount of glue to various positions of the headlight, so as to achieve the purpose of accurately controlling the amount of glue applied, avoid waste of glue and insufficient glue, and ensure uniform coverage of the glue without overflow or dripping.

[0020] like Figure 7 - Fig.10As shown, the angle adjustment mechanism 3 is composed of a rotating assembly 301 and a bevel gear coupling 302, wherein the bevel gear coupling 302 is fixedly mounted at the bottom of the rotating assembly 301; and the rotating assembly 301 is composed of a toothed disc 3011, a gear 3012 and a first servo motor 3013, wherein one side of the toothed disc 3011 is meshedly connected with the gear 3012, and the top of the gear 3012 is provided with a first servo motor 3013 via a shaft, and the first servo motor 3013 is fixedly mounted at the top of the moving seat 206; the bevel gear coupling 302 is composed of a first shaft frame 3021, an active bevel gear 3022, a second servo motor 3023, a driven bevel gear 3024, a spline rod 3025 and a second shaft frame 3026 , the first shaft frame 3021 is fixedly mounted on the bottom of the toothed disc 3011, the active bevel gear 3022 is rotatably mounted inside the first shaft frame 3021, the top of the active bevel gear 3022 is fixedly connected to the output end of the second servo motor 3023 through a shaft rod, and the second servo motor 3023 is fixedly mounted on the top of the toothed disc 3011, through spline holes 3027 are opened on both sides of the second shaft frame 3026, and the second shaft frame 3026 is movably mounted on the bottom of the outer side of the first shaft frame 3021 through the spline rod 3025 and the spline hole 3027, the driven bevel gear 3024 is fixedly mounted on the outer side of the spline rod 3025, and the driven bevel gear 3024 is meshed and connected with the active bevel gear 3022; An encoder is fixedly installed at one end of the spline rod 3025. When the spline rod 3025 adjusts the glue coating angle of the glue mixer 4, the second servo motor 3023 drives the active bevel gear 3022 to rotate. The rotating active bevel gear 3022 drives the spline rod 3025 to rotate through the meshing driven bevel gear 3024. The rotating spline rod 3025 drives the second shaft frame 3026 to flip through the spline hole 3027 connected by the bayonet pin. The encoder detects the rotation angle of the spline rod 3025 to accurately control the flip angle of the second shaft frame 3026 and adjust the glue coating angle of the glue mixer 4. When adjusting the glue application direction of the glue mixer 4, the first servo motor 3013 drives the gear 3012 to rotate, and the rotating gear 3012 drives the meshing toothed disc 3011 to rotate. The rotating toothed disc 3011 drives the glue mixer 4 to rotate through the bevel gear coupling 302 to adjust the glue application direction of the glue mixer 4. By adjusting the glue application angle and glue application direction of the glue mixer 4, the flexibility of the glue application adjustment of the glue mixer 4 is further improved, so that the glue mixer 4 can apply glue to the gaps of headlights with different curves.

[0021] like Fig.11 - Fig.13As shown, the glue mixer 4 is composed of a glue mixing tank 401, an anti-drip glue coating head 402, a position sensor 403, a camera 404 and a protective cover 405. The protective cover 405 is threadedly installed on the top of the glue mixing tank 401, a driving motor 406 is fixedly installed inside the protective cover 405, and a stirring paddle 407 extending to the inside of the glue mixing tank 401 is fixedly installed at the output end of the driving motor 406. A heating tube 408 is fixedly installed on the inner wall of the glue mixing tank 401, the anti-drip glue coating head 402 is fixedly installed on the bottom of the glue mixing tank 401, the position sensor 403 is clamped on the outside of the anti-drip glue coating head 402, and the camera 404 is installed on the outer wall of the glue mixing tank 401 through a suspension rod; Among them, the attached Fig.12 It can be seen that the anti-drip glue coating head 402 is composed of a fixed tube, a telescopic sealing component and a telescopic tube, wherein the fixed tube provides an installation position for the position sensor 403, and the telescopic sealing component is composed of a fixed frame, a rubber block and a spring, the rubber block is movably installed at the bottom of the fixed frame, the spring is fixedly installed at the top of the fixed frame, and the rubber block is in contact with the spring. The top of the telescopic tube is fixedly connected to the bottom of the rubber block through a connecting piece, and the opening and closing of the telescopic tube passage is achieved under the cooperation of the rubber block and the spring. Specifically, when the telescopic tube is subjected to a resistance force, the telescopic tube drives the rubber block to move and compress the spring to open the lower glue opening of the telescopic tube. When the telescopic tube is free of external force, the lower glue opening of the telescopic tube is reset and closed by the spring contacting the rubber block, ensuring that the telescopic tube is automatically sealed when there is no contact with the car light to avoid glue dripping; The top of the protective cover 405 is threadedly connected to the bottom of the second shaft frame 3026 through a threaded hanger. The protective cover 405 can protect the driving motor 406. The driving motor 406 drives the stirring paddle 407 to rotate to mix the A glue and B glue in the mixing tank 401 to form an AB glue mixture. At the same time, the AB glue mixture in the mixing tank 401 is heated by the heating tube 408 to ensure the fluidity of the AB glue mixture. When the AB glue mixture is output, the filtered gas is transported to the inside of the mixing tank 401 by the negative pressure pump 8, so as to pneumatically push the AB glue mixture to the anti-drip glue coating head 402 to avoid the AB glue mixture from remaining. When the anti-drip glue coating head 402 contacts the gap of the headlight, an upward resistance force is generated on the anti-drip glue coating head 402, and the resistance force causes the anti-drip glue coating head 402 to start dispensing glue, and the AB glue mixture is evenly applied to the gap of the headlight through the anti-drip glue coating head 402.

The return spring 5014 is fixedly installed on the bottom of the piston 5012; Among them, the negative pressure pump 8 is powered on to suck the air inside the negative pressure adsorption seat 5 through the pipeline, so that a negative pressure state is formed inside the negative pressure adsorption seat 5, and the car light is placed on the negative pressure adsorption seat 5, and the self-weight of the car light is used to press down the self-weight adsorption mechanism 501, so that the self-weight adsorption mechanism 501 under pressure opens a passage to transmit the negative pressure inside the negative pressure adsorption seat 5 to the car light for negative pressure adsorption, specifically as follows: the self-weight of the car light generates downward pressure on the pressing rod 5013, so that the pressing rod 5013 pushes the piston 5012 to move down to the bottom of the adsorption tube 5011, so that the adsorption tube 5011 forms a negative pressure passage, and the downwardly moved piston 5012 compresses the reset spring 5014, and in the absence of external force on the pressing rod 5013, the reset force of the reset spring 5014 is used to drive the piston 5012 to move up to close the adsorption tube 5011; the car light is positioned by self-weight negative pressure adsorption, thereby ensuring the stability of the car light during the glue coating process.

The solid matter in the glue liquid can be effectively filtered by the filter 604 to ensure the quality of the glue liquid. The glue liquid stored in the A glue tank 602 and the B glue tank 603 are quantitatively transported to the inside of the mixing glue tank 401 by the metering pump 605.

[0024] like Figure 5 , Figure 6As shown, the moving assembly 204 is composed of a sliding sleeve seat 2041 and a wire set 2042.
