Self-positioning and automatic-focusing CCD cylindrical outer contour detection device

Abstract

The invention provides a self-positioning and automatic-focusing CCD cylindrical outer contour detection device. The device comprises a positioning plate, a CCD support arranged on one side of the positioning plate, a parallel plate light source and an automatic focusing mechanism. Symmetrically arranged CCD sliding blocks, CCD guide rails and CCD components are arranged on the upper surface and the lower surface of the CCD support respectively. The parallel plate light source is perpendicular to the positioning plate and is installed parallel to the CCD support. An electric cylinder and a grating ruler are installed on a grating ruler mounting plate. The grating reading head of the grating ruler is connected with the electric cylinder through a connecting rod. A microswitch is installed on the connecting rod. A lead screw mechanism is installed in the middle of the CCD support. The lead screw nuts of the lead screw mechanism are connected with the CCD guide rails. The mounting plate of a motor of the lead screw mechanism is fixedly connected with the CCD support. The device is simple in structure. A to-be-measured cylinder is automatically positioned by the device and the CCD canbe automatically focused. Through setting different parameters, the outer contours of cylinders different in diameter can be measured. The measuring efficiency and the measuring precision are improved.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a self-positioning and auto-focusing CCD cylinder outer contour detection device capable of self-positioning and detection of a measured cylinder. Background technique [0002] It is an extremely important step in industrial production to carry out side profile detection on the front part of the round pipe produced, and it is an important means to detect whether the product is qualified. At present, in order to detect the side profile of the front part of the round pipe produced, hand-held tools are usually used for measurement. This measurement method is not efficient, and the accuracy is difficult to guarantee, which cannot meet the needs of modern industrial production. [0003] In order to improve the measurement efficiency and obtain higher precision, it is urgent to design a device that can automatically measure the front side profile of the round pipe in this fie...
