Lens quality detection device for medical endoscope production

Abstract

The invention relates to the field of medical instrument detection, and discloses a medical endoscope production lens quality detection device, which comprises a main machine body, a test endoscope lens and a PLC controller, the upper end of the main machine body is provided with a driving camera obscura device, the upper end of a workbench is provided with a mobile platform and a test comparison card board, the test endoscope lens is installed on the mobile platform, and the test comparison card board is installed on the PLC controller. An adjusting test target is mounted on the test comparison card board and comprises a mounting rack, a test target and a gear motor, the gear motor is arranged at the bottom of the mounting rack, the test target is mounted on a rotating shaft of the gear motor, and a light source component is arranged in the test target. The device provided by the invention solves the problems that in the prior art, manual inlaying of camera obscura parts is easy to collide and relatively time-consuming and labor-consuming, the angle of a measurement target cannot be adjusted, and time-consuming and labor-consuming installation and disassembly of an endoscope are realized; the detection of the field angle, the direction angle, the visual resolution, the geometric distortion, the color rendition capability and the lighting effect of the endoscope lens is realized.

Description

technical field [0001] The invention relates to the field of medical instrument detection, in particular to a quality detection device for a production lens of a medical endoscope. Background technique [0002] An endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. In the medical field, endoscopes are used to look inside the body to examine organs. An endoscope can examine the gastrointestinal, respiratory and urinary tracts and internal organs through a small incision. The endoscope captures images through its long or tough tube. Additional instruments for cutting, grasping, and other functions are often attached to the endoscope to perform minimally invasive procedures that improve medical care and reduce recovery time. In the production process of endoscopes, it is not only necessary to test the different accessories installed, but also to test the optical performance of t...
