The optical screening machine uses CCD camera to convert the detected target into image signal, and converts it into digital signal according to the pixel distribution, brightness, color and other information. The image processing system performs various operations on these signals to extract the characteristics of the target, such as area, quantity, position, length, and then outputs the results according to the preset permissibility and other conditions, including multi-segment height, multi-segment width, broken needle, and plug hole, Invalid tooth length (lower neck tooth height), tooth base diameter, tooth outer diameter, tooth pitch, oblique tooth, bad tooth rubbing, screw length, head plating, chamfer, plug hole, eccentricity, tooth, etc., thus realizing automatic detection and recognition function.

Definition and purpose of tensile machineTensile machine, also known as tensile testing machine or material testing machine, is a mechanical afterburner used to test the mechanical properties of materials such as tension, compression, bending, shearing and peeling.

The salt spray test machine is applicable to the salt spray test of automobile parts, electronic components, protective layer of metal materials and industrial products. Standard parts salt spray test, hardware salt spray test, fastener salt spray test, electroplating salt spray test, screw salt spray test, spring salt spray test, metal products salt spray test, automobile parts salt spray test. The salt spray test machine is one of the three prevention (damp heat, salt spray, mold) test equipment in the artificial climate environment. It is used for neutral salt spray test and also for acetate spray test.
