[0016] The present utility model will be further described below with reference to the accompanying drawings.

[0017] Refer to Figure 1-2 As shown, an automotive headlight welding device with high working efficiency includes a base 1, a turntable 2, and a loading mold 3. The turntable 2 is rotatably arranged on the upper surface of the base 1, and the loading molds 3 are arranged on the upper surface of the turntable 2 at equal circumferences. A receiving groove matching the headlight is formed inside the loading mold 3. Specifically, the headlight housing and the lamp cover can be placed up and down together and placed inside the receiving groove of the loading mold 3. The loading mold 3 positions the components, preventing them from shifting during the rotation of the turntable 2 and making the welding more accurate.

[0018] One end of the turntable 2 is provided with a first mounting seat 4. A vertically arranged first column 5 is provided on the first mounting seat 4. A driving member 6 is slidably arranged on the front end face of the first column 5. An ultrasonic welding assembly 7 is provided on the front end face of the driving member 6. The ultrasonic welding assembly 7 generates frictional heat at the interface between two components through high-frequency ultrasonic vibration, thereby instantly melting and then cooling and solidifying to weld the two components together. This is prior art and will not be elaborated in detail here. A lifting drive assembly for driving the driving member 6 to reciprocate up and down is provided on the first column 5. Two guide rails 15 are symmetrically arranged on the front end face of the first column 5. The rear end face of the driving member 6 is slidably connected to the two guide rails 15. The lifting drive assembly includes an adjusting screw 1601, a through groove 1602, and a third motor 1603. The first column 5 is a hollow structure. The adjusting screw 1601 is rotatably arranged inside the first column 5. The through groove 1602 is formed on the front end face of the first column 5, between the two guide rails 15. The middle of the rear end face of the driving member 6 passes through the through groove 1602 and is threadedly connected to the adjusting screw 1601. The third motor 1603 is arranged at the top of the first column 5, and the driving end is connected to the adjusting screw 1601. The third motor 1603 drives the adjusting screw 1601 to rotate, driving the driving member 6 to reciprocate up and down along the adjusting screw 1601 and the guide rails 15, driving the ultrasonic welding assembly 7 to approach or move away from the loading mold 3 on the turntable 2.

[0019] On one side of the turntable 2, a second mounting base 8 is rotatably arranged. On the second mounting base 8, a second vertical column 9 is arranged in a vertical state. At the top of one side of the second vertical column 9, a horizontal arm 10 is arranged horizontally. The horizontal arm 10 is perpendicular to the second vertical column 9. At the top end of the horizontal arm 10, a lifting cylinder 11 is arranged. Below the horizontal arm 10, a suction cup assembly 12 connected to the driving end of the lifting cylinder 11 is arranged. The lifting cylinder 11 drives the suction cup assembly 12 to move up and down reciprocally, approaching or departing from the welded headlight. The suction cup assembly 12 is evacuated by a vacuum pump to form a vacuum suction force between the suction cup and the object surface, thereby fixedly adsorbing the object. This is prior art and will not be elaborated in detail here. Inside the base 1, a first motor 13 for driving the turntable 2 to rotate and a second motor 14 for driving the second mounting base 8 to rotate are arranged. The first motor 13 drives the turntable 2 to rotate on the upper surface of the base, so that the loading mold 3 loaded with the object is successively corresponding to the ultrasonic welding assembly 7 and the suction cup assembly 12.

A conveyor belt assembly can be arranged on one side of the base 1. The second motor 14 drives the second mounting base 8 to rotate, so that the suction cup assembly 12 and the headlight move above the conveyor belt assembly. Then, the lifting cylinder 11 drives the suction cup assembly 12 to descend, and the headlight is placed on the conveyor belt assembly.

[0020] In the working process of the present utility model, after the staff places the headlight components together, they are placed inside a loading mold 3. The first motor 13 drives the turntable 2 to rotate, so that the loading mold 3 with the placed headlight rotates below the ultrasonic welding assembly 7. At the same time, the staff continuously places the headlight components on other loading molds 3. At the same time, the lifting drive assembly drives the driving member 6 to move downward along the first vertical column 5, so that the ultrasonic welding assembly 7 contacts the headlight components for welding, and then rises and resets. The welded headlight then rotates to directly below the suction cup assembly 12 by the turntable 2. The lifting cylinder 11 drives the suction cup assembly 12 to descend, adsorb and grab the headlight, rises and resets. Then, the second motor 14 drives the second mounting base 8 and the second vertical column 9 to rotate to the side away from the turntable 2. Then, the lifting cylinder 11 drives the suction cup assembly 12 and the welded headlight to descend and place them on the external conveyor belt assembly, and then resets. While taking the headlight away from the loading mold 3, the ultrasonic welding assembly 7 simultaneously welds the headlight components on the next loading mold 3. The staff only needs to perform the feeding operation, and can weld and unload by themselves. The whole process does not require shutdown and waiting, has good working continuity, high automation degree, and effectively improves the welding and assembly efficiency.
