[0027] In some embodiments, referring to Figure 2 and Figure 3 The gripper frame 110 is processed by a profile, specifically including a first frame 111 and a second frame 112 arranged in parallel, and a plurality of support columns 113 fixedly supported between the first frame 111 and the second frame 112, the fabric gripper 120 is installed on the first frame 111, and the press-over gripper 130 is installed on the second frame 112.

[0028] The fabric gripper 120 is used to grab the coated fabric 400.

[0029] In some embodiments, referring to Figure 2 The fabric gripper 120 includes four needle suction cups 121 respectively arranged at the four corners of the gripper frame 110.

[0030] In order to facilitate the installation of the gripper frame 110, the four corners of the gripper frame 110 located on one side of the fabric gripper 120 are respectively provided with needle suction cup mounting plates 122 protruding outward, and each needle suction cup 121 is correspondingly installed on the protruding end of each needle suction cup mounting plate 122.

[0031] The needle suction cup 121 can adopt a Geli needle suction cup 121, and the principle of grabbing is that the air pressure in the chamber is controlled through the air inlet to make the spring of the elastic component push the piston to move, thereby driving the needle body to extend or retract. When the needle body extends, it penetrates into the surface of the material, and the material is grabbed by using the friction and mechanical biting effect between the needle and the material; when the material needs to be released, the needle body retracts, and the material can be separated from the suction cup. This technology is prior art, and will not be described here.

[0032] The needle suction cup 121 can reliably grab the coated material, and the four Geli needle suction cups 121 evenly distributed at the four corners of the gripper frame 110 can well open and flatten the coated fabric 400.

[0035] The sun visor shell 300 is two halves, and two over-molding single frames are arranged, each over-molding single frame is pressed on a corresponding sun visor shell 300, so that when the over-molding machine 500 is hot-melted and over-molded with the fabric 400, the over-molding frame 131 can ensure that the edges of the two halves of the sun visor shell 300 are pressed in the mold 510, thereby ensuring the over-molding quality. At the same time, the picking assembly 132 adopts the structure of the vacuum suction cup 1321, which can respectively adsorb the two halves of the sun visor shell 300 and tightly attach to the corresponding over-molding single frame.

[0036] Preferably, the over-molding single frame includes a bottom frame 1311 fixed on the gripper frame 110, a pressing frame 1312 arranged on the side of the bottom frame 1311 away from the gripper frame 110, and a plurality of columns 1313 fixedly supported between the bottom frame 1311 and the pressing frame 1312, and the shape of the pressing frame 1312 is the same as that of the automobile sun visor, so that the pressing frame 1312 can be pressed on the edge of the sun visor shell 300.
