Description

Technical Field

[0001] This utility model relates to the field of sealing and gluing technology for vehicle lamp assembly, specifically a sealing and gluing device for vehicle lamp assembly. Background Technology

[0002] The sealing and gluing process for vehicle headlight assembly involves applying adhesive to the assembled headlights using a gluing device. This is crucial for ensuring the headlights' airtightness. The gluing device consists of an adhesive supply system comprised of a glue tank, a pressure regulating device, and gluing nozzles. It also includes a positioning platform for fixing and placing the headlights, and a human-machine interface integrated display for controlling the adhesive supply system. The principle is to use a glue pump to deliver adhesive to the gluing nozzles, and then have the operator manually apply the gluing nozzles to the headlights on top of the positioning platform. By changing the gluing nozzles and adjusting the motion control program, it can quickly adapt to various gluing needs based on different types and shapes of headlights.

[0003] In current technologies, when using an adhesive applicator to seal assembled vehicle lights, adhesive drips onto the positioning table. Once the adhesive on the positioning table solidifies, it affects the placement of the vehicle lights, causing misalignment in the adhesive application position. Therefore, workers need to manually clean the solidified adhesive from the positioning table, increasing their workload and reducing the efficiency of the vehicle light sealing process. Hence, this invention proposes a vehicle light assembly sealing adhesive applicator to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vehicle headlight assembly sealing adhesive application device. This device automatically cleans the solidified adhesive from the positioning workbench, solving the problem that when using an adhesive application device to seal assembled vehicle headlights, adhesive drips onto the positioning workbench, and after solidification, affects the placement of the headlights, causing misalignment in the adhesive application position. Therefore, workers are required to manually clean the solidified adhesive from the positioning workbench, increasing their workload and reducing the efficiency of the headlight sealing process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing adhesive applicator for vehicle headlight assembly, comprising an adhesive applicator fixture, wherein the adhesive applicator fixture is provided with a positioning table and an adhesive tank, the bottom of the adhesive tank is provided with an adhesive nozzle, and the adhesive applicator fixture is provided with a cleaning structure and a driving structure.

[0006] The cleaning structure includes a support frame fixedly installed on the adhesive application fixture. A connecting block is slidably installed inside the support frame. A connecting component is fixedly installed on the front of the connecting block. An installation frame is fixedly installed inside the connecting component. A cleaning block for cleaning the solidified adhesive on the top of the positioning table is slidably installed inside the installation frame. A pressing component for controlling the up and down movement of the cleaning block is fixedly installed on the top of the installation frame.

[0007] Furthermore, the drive structure includes a threaded rod rotatably mounted between the left and right side walls of the inner cavity of the support frame and used to control the left and right movement of the connecting block. The connecting block is threaded onto the outer surface of the threaded rod. A three-phase motor is fixedly mounted on the top of the support frame, and a transmission component for driving the threaded rod to rotate is provided on one side of the three-phase motor.

[0008] Furthermore, the positioning workbench and the glue tank are both fixedly installed on the glue application fixture, the glue application nozzle is installed at the bottom of the glue tank, and a corrugated pipe is fixedly connected between the glue tank and the glue application nozzle.

[0009] Furthermore, a limiting block is fixedly installed on the back of the connecting block, and a limiting groove is opened on the rear side wall of the inner cavity of the support frame. One end of the limiting block passes through and extends into the interior of the limiting groove, and the inner wall of the limiting groove is slidably connected to the outer surface of the limiting block.

[0010] Furthermore, the connecting component includes a connecting frame and a fixing screw. One end of the fixing screw passes through the connecting frame and extends into the interior of the connecting block. The fixing screw is threadedly connected to the connecting block. The left and right side walls of the inner cavity of the connecting frame are respectively fixedly connected to the left and right sides of the mounting frame.

A pressure sensor electrically connected to the three-phase motor is fixedly installed on the cleaning block.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This vehicle headlight assembly sealing and adhesive application device, through the inclusion of a cleaning structure and a drive structure, enables the cleaning block inside the mounting frame to move downwards using an electric push rod in the pressing component. The cleaning block moves downwards until it abuts the top of the positioning table, triggering a pressure sensor. This, in turn, activates a three-phase motor, which then uses mechanical transmission to control the rotation of a threaded rod. This causes the connecting block, threaded on the outer surface of the threaded rod, to move the mounting frame to the left via a connecting component. This, in turn, controls the cleaning block to be fed to the left, thus cleaning the solidified adhesive on the top of the positioning table. This automated cleaning process replaces manual cleaning of solidified adhesive, ensuring the balance and stability of the vehicle headlight, reducing the workload of workers, and enhancing the practicality of the vehicle headlight assembly sealing and adhesive application device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This embodiment of a vehicle headlight assembly sealing adhesive application device includes an adhesive application fixture 1, on which a positioning table 2 and an adhesive tank 3 are provided. An adhesive application nozzle 4 is provided at the bottom of the adhesive tank 3. The adhesive application fixture 1 is provided with a cleaning structure and a driving structure. The positioning table 2 and the adhesive tank 3 are both fixedly installed on the adhesive application fixture 1. The adhesive application nozzle 4 is installed at the bottom of the adhesive tank 3. A corrugated pipe is fixedly connected between the adhesive tank 3 and the adhesive application nozzle 4.

[0021] In this embodiment, the cleaning structure includes a support frame 51 fixedly installed on the adhesive application fixture 1. A connecting block 52 is slidably installed inside the support frame 51. A limit block is fixedly installed on the back of the connecting block 52. A limit groove is formed on the rear side wall of the inner cavity of the support frame 51. One end of the limit block passes through and extends into the interior of the limit groove. The inner wall of the limit groove is slidably connected to the outer surface of the limit block, thereby restricting the trajectory of the connecting block 52 moving left and right inside the support frame 51. A connecting component 53 is fixedly installed on the front of the connecting block 52. The connecting component 53 includes a connecting... The frame and fixing screws are provided. One end of the fixing screw passes through the connecting frame and extends into the interior of the connecting block 52. The fixing screw is threadedly connected to the connecting block 52. The left and right side walls of the inner cavity of the connecting frame are fixedly connected to the left and right sides of the mounting frame 54, respectively, to facilitate the disassembly and assembly of the connecting component 53 on the front of the connecting block 52. The mounting frame 54 is fixedly installed inside the connecting component 53. A cleaning block 55 for cleaning the solidified adhesive on the top of the positioning workbench 2 is slidably installed inside the mounting frame 54. A pressing component 56 for controlling the up and down movement of the cleaning block 55 is fixedly installed on the top of the mounting frame 54.

[0022] The pressing component 56 includes a mounting bracket and an electric push rod. The mounting bracket is fixedly connected to the left and right sides of the mounting frame 54 respectively. The electric push rod is fixedly installed on the mounting bracket. The telescopic end of the electric push rod is fixedly connected to the top of the cleaning block 55, so that the extension of the electric push rod can be used to control the cleaning block 55 to press against the top of the positioning table 2.

[0023] Using the above technical solution, the electric push rod in the starting pressing component 56 is activated. The electric push rod extends and pushes the cleaning block 55 inside the mounting frame 54 downward, so that the downwardly moving cleaning block 55 abuts against the top of the positioning table 2. Then, the drive structure controls the connecting block 52 to drive the mounting frame 54 to move to the left through the connecting component 53. This causes the moving mounting frame 54 to drive the cleaning block 55 to be fed to the left, and the fed cleaning block 55 cleans the solidified adhesive on the top of the positioning table 2.

[0024] In this embodiment, the drive structure includes a threaded rod 57 rotatably mounted between the left and right side walls of the inner cavity of the support frame 51 and used to control the left and right movement of the connecting block 52. The connecting block 52 is threaded onto the outer surface of the threaded rod 57. A three-phase motor 58 is fixedly mounted on the top of the support frame 51. A transmission component 59 for driving the threaded rod 57 to rotate is provided on one side of the three-phase motor 58. The transmission component 59 includes a belt and two pulleys. The two pulleys are fixedly mounted on the output shaft of the three-phase motor 58 and the outer surface of the threaded rod 57, respectively. The belt drive is mounted on the two pulleys, so that the rotating output shaft drives the threaded rod 57 to rotate by the belt.

[0025] The cleaning block 55 is fixedly equipped with a pressure sensor that is electrically connected to the three-phase motor 58, so that the cleaning block 55 can press against the top of the positioning table 2 and trigger the pressure sensor, thereby triggering the three-phase motor 58 on the top of the support frame 51.

[0026] Using the above technical solution, the cleaning block 55 that moves downwards abuts against the top of the positioning table 2 and triggers the pressure sensor, thereby triggering the three-phase motor 58 at the top of the support frame 51. The three-phase motor 58 drives the output shaft to rotate, and the rotating output shaft drives the threaded rod 57 to rotate via the belt in the transmission component 59. This controls the connecting block 52 connected to the threaded rod 57 and drives the mounting frame 54 to move to the left through the connecting component 53.

[0027] The working principle of the above embodiments is as follows:

[0028] When using the sealing and gluing device for the vehicle headlight assembly, the electric push rod in the pressing component 56 is activated. The electric push rod extends and pushes the cleaning block 55 inside the mounting frame 54 downward. The downward-moving cleaning block 55 abuts against the top of the positioning table 2 and triggers the pressure sensor, which in turn triggers the three-phase motor 58 on the top of the support frame 51. The three-phase motor 58 drives the output shaft to rotate, and the rotating output shaft drives the threaded rod 57 to rotate via the belt in the transmission component 59. This controls the connecting block 52 connected to the threaded rod 57 and drives the mounting frame 54 to move to the left through the connecting component 53. The moving mounting frame 54 then drives the cleaning block 55 to the left, and the fed cleaning block 55 cleans the solidified glue on the top of the positioning table 2.
