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.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a welding device for automotive headlight production, including a support base 1, a support top frame 2 fixedly connected to the top of the support base 1, a first cylinder 5 mounted on the top of the support top frame 2, a fixed base box 6 fixedly connected to the output end of the first cylinder 5, an upper support block 8 mounted on the bottom of the fixed base box 6, a plurality of first vacuum suction cups 9 equidistantly mounted on the bottom of the upper support block 8, a mounting bracket 3 slidably connected to the inner side of the support top frame 2, a lower support block 4 bolted to the top of the mounting bracket 3, and a lower support block 4 equidistantly mounted on the top of the lower support block 4. The device is equipped with multiple second vacuum suction cups 10. A vacuum generator is installed at one end of both the first vacuum suction cup 9 and the second vacuum suction cup 10. An inner ventilation frame 11 is fixedly connected to the inner side of the support top frame 2. Multiple blowers 12 are fixedly connected at equal intervals to the inner side of the inner ventilation frame 11. A support base 14 is provided between the lower support block 4 and the upper support block 8. Heating blocks that cooperate with the upper support block 8 and the lower support block 4 are respectively provided at the top and bottom of the support base 14. The shell supported on the upper support block 8 and the lower support block 4 is heated and welded by the heating blocks at the top and bottom of the support base 14.

[0018] The top of the upper support block 8 is symmetrically fixedly connected with a mounting top block 19. The bottom of the fixed base box 6 is symmetrically provided with mounting bottom grooves 20 that cooperate with the mounting top block 19. The inner side of the mounting top block 19 is provided with a mounting side groove 21. The inside of the fixed base box 6 is symmetrically slidably connected with a limiting mounting block 22 that cooperates with the mounting side groove 21. The mounting top block 19 on the top of the upper support block 8 enters into the mounting bottom groove 20, and the limiting mounting block 22 enters into the mounting side groove 21 inside the mounting top block 19, so that the mounting top block 19 and the upper support block 8 are installed and fixed at the bottom of the fixed base box 6.

[0019] The fixed base box 6 is internally connected to a bidirectional lead screw 23, and the outer side of the bidirectional lead screw 23 is symmetrically threaded with a movable slider 24. One side of the movable slider 24 is fixedly connected to the limiting mounting block 22, and the movable slider 24 is slidably connected to the fixed base box 6. When the bidirectional lead screw 23 is rotated, the outer movable slider 24 moves within the fixed base box 6. The movable slider 24 moves the limiting mounting block 22, thus completing the installation and disassembly of the mounting top block 19 and the upper support block 8.

[0020] The double-acting lead screw 23 is fixedly connected to the outer side of a worm gear 25. The fixed base box 6 is rotatably connected to a worm 26, which meshes with the worm gear 25. A rotating screw block 15 is rotatably connected to one side of the fixed base box 6. One end of the worm 26 is fixedly connected to the rotating screw block 15. The rotating screw block 15 facilitates the rotation adjustment of the worm 26 inside the fixed base box 6. The worm 26 rotates and adjusts the meshing worm gear 25. When the worm gear 25 rotates, it drives the double-acting lead screw 23 on the inner side to rotate and adjust.

[0021] The top of the fixed base box 6 is symmetrically and fixedly connected to a first limiting slide rod 7, which is slidably connected to the support top frame 2. The top of the inner ventilation frame 11 is fixedly connected to an air inlet pipe 13. The bottom of the support base 1 is equipped with a third cylinder 28, the output end of which is fixedly connected to the mounting bracket 3. The bottom of the mounting bracket 3 is symmetrically and fixedly connected to a third limiting slide rod 29, which is slidably connected to the support base 1. The air inlet pipe 13 is connected to an external fan, and the input end of the fan is connected to the air inlet pipe 13. Air is blown into the inner ventilation frame 11 through the air inlet pipe 13 and blown out through each blower head 12 on the inner side of the inner ventilation frame 11 to heat up the welded car headlights.

[0022] The top of the support base 1 is fixedly connected to a fixed support plate 27. A second cylinder 17 is installed on one side of the fixed support plate 27. An adjusting support 16 is fixedly connected to the output end of the second cylinder 17. One side of the adjusting support 16 is bolted to the support base 14. A second limiting slide rod 18 is symmetrically fixedly connected to one side of the adjusting support 16. The second limiting slide rod 18 is slidably connected to the fixed support plate 27. The output end of the second cylinder 17 drives the adjusting support 16 and the support base 14 to adjust their positions, which facilitates the adjustment of the position of the support base 14 inside the support top frame 2.

[0023] Specifically, in use, the support base 14 is installed on one side of the adjusting support 16 using bolts. The mounting top block 19 on the top of the upper support block 8 enters the mounting groove 20. By rotating the rotating screw block 15, the rotating screw block 15 drives the worm gear 26 to rotate and adjust. When the worm gear 26 rotates, it drives the meshing worm wheel 25 to rotate. When the worm wheel 25 rotates, it drives the inner double-acting screw 23 to rotate and adjust. The double-acting screw 23 moves and adjusts the outer symmetrical sliding block 24. The sliding block 24 is then moved and adjusted. 4. Drive the limiting installation block 22 into the installation side groove 21 inside the installation top block 19, and install and fix the installation top block 19, upper support block 8 and fixed base box 6. Power on the device through an external power supply and operate the device through an external controller. Install the lower support block 4 on the top of the installation support 3 and install the upper shell on the bottom of the upper support block 8. Fix the position of the upper shell at the bottom of the upper support block 8 through the first vacuum suction cup 9 at one end of the vacuum generator. The second vacuum suction cups 10 on the top of the lower support block 4 fix the upper shell at the bottom of the lower support block 4. The lower shell is placed and fixed. The output end of cylinder 28 drives the mounting bracket 3 and the lower support block 4 to move upward, so that the lower shell fits into the heating block at the bottom of the support base 14. The output end of cylinder 5 drives the fixed base box 6 and the upper support block 8 to move downward, so that the upper shell at the bottom of the upper support block 8 fits into the heating block at the top of the support base 14. The heating block electrothermally melts the upper and lower parts of the headlight and welds the plastic parts of the headlight. The output end of cylinder 17 drives the adjusting bracket 16 and the support base 14 to move outward. At this time, the output end of cylinder 28 continues to drive the mounting bracket 3, the lower support block 4 and the lower shell to move upward, while the output end of cylinder 5 continues to drive the fixed base box 6, the upper support block 8 and the upper shell to move downward, so that the upper shell and the lower shell are fitted together and the automotive headlight is produced and welded. The air inlet pipe 13 is connected to an external fan, and the input end of the fan is connected to the air inlet pipe 13. Air is blown into the inner ventilation frame 11 through the air inlet pipe 13 and blown out through the various blower heads 12 inside the inner ventilation frame 11 to heat up the welded automotive headlight.
