[0038] The fastening clamp 8 is provided in several parts and installed on the upper and lower surfaces of the mold table 5. The fastening clamp 8 clamps the mask and the outer shell after they are fastened, so as to realize the automatic fastening of the mask and the outer shell, and achieve the purpose of mask gripping, outer shell gripping, and mask and outer shell fastening.

[0039] In this embodiment, as Figure 1 As shown, a base 1 is installed at the lower end of the robotic arm 2, which provides stable support for the robotic arm 2. A reinforcing seat 13 for supporting the robotic arm 2 is provided on the base 1, which can ensure the stable operation of the robotic arm 2 and guarantee the accuracy of the vehicle headlight movement.

[0040] In this embodiment, as Figure 1 As shown, the jig frame 4 is equipped with a quick-change plate 3, which is connected to the robotic arm 2. The jig frame 4 can be quickly removed through the standardized interface of the quick-change plate 3, making it faster to assemble different models of vehicle lights.

[0041] In this embodiment, as Figure 2 and Figure 3 As shown, the surface of the mold table 5 is provided with several integrally formed auxiliary positioning blocks 10. The auxiliary positioning blocks 10 limit the sides of the mask and the outer shell, which can improve the fastening stability of the mask and the outer shell, and make the gripping of the mask and the outer shell more stable.

[0042] In this embodiment, as Figure 2 and Figure 3 As shown, a first cylinder 11 is installed on the lower surface of the mold platform 5. The first cylinder 11 is connected to a push plate 12. When the mask and the outer shell are fastened together, the first cylinder 11 pushes the outer shell toward the mask through the push plate 12 to achieve the positioning and fastening of the mask and the outer shell.

[0043] In this embodiment, as Figure 5 As shown, the mask clamp 7 includes a second cylinder 71, and a first hinge seat 72 is installed at the end of the second cylinder 71. The first hinge seat 72 is movably connected to the latch 73 through a sliding groove 74. A first limiting shell 76 and a first positioning frame 75 are installed on the second cylinder 71. The latch 73 is located inside the first limiting shell 76 and is rotatably connected to the first positioning frame 75. The sliding groove 74 allows the second cylinder 71 to control the latch 73 to rotate and extend out of the first limiting shell 76.

The latch 73 extends out from the first limiting shell 76 and contacts the mask, thus cooperating with the suction cup 6 to grasp and clamp the mask.

[0047] Robotic arm 2 controls the mask to move onto the outer shell. First cylinder 11 controls push plate 12 to move. Push plate 12 adjusts the position of the outer shell to align with the mask. Fourth cylinder 91 pushes arc claw 94 to extend from guide groove 96. Arc claw 94 contacts the outer shell and presses the outer shell onto the mask. Then, robotic arm 2 can move the outer shell to the glue application station. Fourth cylinder 91 controls arc claw 94 to retract. The outer shell is placed in the glue application station for glue application.

[0048] After the adhesive is applied, the push plate 12 adjusts the position of the outer shell, and the arc-shaped claw 94 contacts the outer shell again to clamp it. Then, the third cylinder 81 pushes the snap-fit ​​claw 82 to move, and the pin 85 controls the snap-fit ​​claw 82 to move in the guide hole 84, so that the snap-fit ​​claw 82 presses the outer shell at various positions, thereby pressing the outer shell and the mask together and completing the fastening of the outer shell and the mask. The fastened outer shell and mask are then transported by the robotic arm 2 to the next work station.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
