Description

Technical Field

[0001] The utility model relates to the technical field of automobile headlight processing, in particular to a hot-melt connection device for automobile headlights. Background Art

[0002] Automobile headlights, also known as front lamps, are important lighting fixtures used to provide visibility ahead during nighttime driving. They are symmetrically mounted on either side of the vehicle's front end. The headlights have a complex internal structure, including components such as a lampshade, lens, reflector, bulb, and control panel. The existing publication number CN204296024U describes a dedicated hot-melt machine for hot-melt columns for automotive trim. The machine comprises an electrical control box supported by a support frame at the top of the machine body. A hot-melt platform is located on the top of the machine body. Guide shafts are located at the four corners of the hot-melt platform. A middle movable plate and an upper movable plate are mounted on the guide shafts via linear bearings. A mounting plate is located at the top of the guide shaft. A cylinder is mounted on the mounting plate. The cylinder's output end is connected to the upper movable plate. Connecting columns, springs, and forming limit columns are located at the four corners between the middle movable plate and the upper movable plate. Preheating limit columns are located at the four corners between the middle movable plate and the hot-melt platform. A hot-melt forming head is fixed to the upper movable plate, while a heating block and preheating head are fixed to the middle movable plate. During the hot melting process, the hot melt column is preheated and softened, and then the hot melt column is pressed by the forming melt head. The hot melting process is completed in two actions; thus avoiding the problem of insufficient strength of the hot melt column caused by directly pressing down on the hot melt column.

[0031] The cleaning assembly 5 includes a mounting groove 501, which is formed through one side of the upper surface of the mounting frame 2. A rack 502 is provided in the mounting groove 501. Limiting plates 503 are fixedly installed on both sides of the inner wall of the mounting groove 501. Limiting grooves 5031 are formed on both sides of the rack 502. The two limiting plates 503 are slidably arranged in the corresponding limiting grooves 5031.

[0032] A driving structure 504 for driving the rack 502 to move is provided on one side of the lower surface of the mounting frame 2;

[0033] An annular scraper 506 is fixedly mounted on the lower surface of the rack 502 via a bracket 505 .

[0034] The driving structure 504 includes two vertical plates 5041, and the two vertical plates 5041 are fixedly mounted on both sides of the lower surface of the mounting frame 2;

[0035] A rotating rod 5042 is rotatably installed between the two vertical plates 5041, and a gear 5043 is fixedly installed in the middle of the rod body of the rotating rod 5042. A first motor 5044 is fixedly installed on the side of one of the vertical plates 5041 away from the gear 5043. One end of the rotating rod 5042 passes through the corresponding vertical plate 5041 and is fixedly connected to the output shaft end of the first motor 5044.

[0036] The staff starts the robotic arm 1 to drive the hose 4 to move to the position of the car headlight, and then the staff starts the hot melt device 3 to make the hose 4 apply the hot melt adhesive to the hot melt welding position of the car headlight.
