[0028] Example 2

[0029] An automatic assembly method for an automobile lamp housing adopts the above-mentioned automatic assembly and detection equipment for automobile lamp housing to complete the assembly of the inner parts of the lamp housing.

[0031] Then take out the card clips from the material box one by one, and then install them one by one in the corresponding position of the fixture to prevent reverse installation of the U-shaped buckle mechanism. Press the start button, and the proximity switch will automatically clamp after detecting that the card clip is in place. The cylinder moves to push the card clip into the lamp housing; the magnetic ring detects that it is in place, and at the same time the servo motor rotates to screw in the hollow nut. After the electronic ruler is in place, the motor stops, the cylinder retracts, and the ball screw is taken from the material box. It is placed in the corresponding position of the lamp housing by hand and manually driven into the housing with a screwdriver. Through the cooperation of the automatic installation nut mechanism, the electronic ruler detection mechanism 1 and the electronic ruler detection mechanism 2, the torque is detected in place, the electric screwdriver stops, and the cylinder is loosened. If the torque is unqualified, the equipment will alarm and the clamping cylinder will not be loosened.

[0032] Take the wiring harness from the material box and install it into the housing. Use a special tool to screw in the wiring harness head. Use a special tool to tighten the wire clamp. Then manually organize the wires and pass the wiring harness in place and error-proofing detection mechanism detection. Release all clamping and positioning devices such as clamping mechanism 1, clamping mechanism 2, and slotting positioning mechanism. Take out the assembled housing, and complete the assembly of the internal components of the headlight housing.

[0033] Through the coordination between the automatic installation nut mechanism, the clamping mechanism, the slotting positioning mechanism, and the clamping mechanism, semi-automatic installation is effectively achieved, which saves manpower and improves production efficiency, and effectively avoids scraps and other waste caused by unfixed installation during manual operation. At the same time, through the coordination detection of the anti-reverse installation U-shaped buckle mechanism, the electronic ruler detection mechanism, the wiring harness in place and the anti-error detection mechanism, the problems of missing installation, reverse installation, and inadequate assembly during manual operation are effectively prevented.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
