Please refer to Fig. 1 and Fig. 2, which shows a plastic frame fixture for automatic image alignment, including a substrate 1, the overall shape of the substrate 1 is a rectangle, and the two short sides of the substrate 1 are respectively Several fixing holes 14 are provided for fixing the jig on the machine table. The openings of the fixing holes 14 are provided with grooves for accommodating screw caps to prevent the screw caps from protruding from the surface of the jig after the screws are tightened. The center of the substrate 1 is provided with a central hole 12 perpendicular to the plane of the substrate 1 and penetrating the substrate 1. The central hole 12 is a detection hole for the infrared radiation product of the infrared sensor, that is, the central hole 12 is used for avoiding the air sensor. . In order to accurately fix the fixture on the machine platform, several positioning holes 13 are provided around the central hole 12 to locate the position of the fixture on the machine platform, and then fixed on the two short sides of the base plate 1 by screws. in hole 14.

Specifically, an accommodating tank 2 for placing products is provided in the middle of the substrate 1. In order to make the product adsorbed in the accommodating tank 2 without moving, several air suction holes 9 are provided at the bottom of the accommodating tank 2. The air hole 9 generates a negative pressure in the storage tank 2, which can make the product adsorb in the storage tank 2 and prevent the product and the substrate 1 from moving relative to each other. On the four corners of the accommodating tank 2 on the substrate 1, there are photo-avoiding slots 3, the number of which is four, and each photo-avoiding slot 3 is close to the two sides of the accommodating tank 2 All are provided with a U-shaped photo taking point avoidance groove 4, which is used for taking pictures and avoiding the impact of reflection on the surface of the fixture to take pictures.
