Device and method for automatically detecting fit dimension of surgical knife blade

Abstract

The invention relates to a device and a method for automatically detecting fit dimension of a surgical knife blade, wherein a camera consists of a CMOS image sensor and a CMOS camera, a skewed tooth upright post guide rail is fixedly connected on a detection platform through a guide rail base, a skewed tooth groove of the upright post guide rail is connected with a fixed guide rail sliding block, the front part of the guide rail sliding block is fixedly connected with a camera stander, and the upside of the camera stander is fixed with the camera; the downside of the camera is fixed with a lifting platform; a platform under the camera is placed with a light source lamp, the center of a camera lens, the center of the lifting platform and the centers of a calibration measuring block and a blade are on the same vertical line; and the camera is connected with a computer through a USB 2.0 universal serial bus interface. The device and the method can effectively detect all data indexes of the surgical knife blade so as to quickly and accurately detect whether a product accords with the design requirement, and have the characteristics of high precision, high speed and no touch.

Description

technical field [0001] The invention relates to an automatic detection device, in particular to an automatic detection device and a detection method for the matching size of a surgical blade. Background technique [0002] The scalpel handle and the detachable blade need to have good compatibility and interchangeability, so the matching size detection of the blade is a very common and practical problem in the quality control of surgical blades. At present, domestic surgical blade manufacturers mainly adopt manual measurement methods, such as using universal tool microscopes, grating rulers, angle gauges and other tools to measure the size of surgical blades. This traditional manual visual inspection is time-consuming, labor-intensive and inefficient, and human error is inevitable. Contents of the invention [0003] The present invention is aimed at the problem that the current measurement method is still maintained in a manual state, and there are errors and low efficiency...
