Problems solved by technology

However, the profiling method needs to make a special template. When there are many types of products, not only the cost of making the template is high, but also the management and replacement of the template are troublesome. If the processed product is large, it is necessary to make a template in addition to the processing workbench The countertop makes the entire equipment occupy too much space. In addition, the product outline graphics formed by it cannot be queried, modified and further analyzed
This method can only be used for simple copy processing of existing products, and it is difficult to be used for redevelopment and improvement of products, which does not meet the needs of modern production management

Abstract

The invention relates to a contact type large heterotypic glass gabarit detection device and a method based on rotary-straight line motion. The device comprises a computer and a test desk which is used for arranging detected heterotypic glass and can do straight line motion and rotary motion. The computer is connected with a motion control card through a bus line. The motion control card is connected with a connection board through an I / O interface. The connected board is connected with a straight line motion servo driver, a rotary motion servo driver and a displacement sensor. The straight line motion servo driver is connected with a first servo motor which does carry out the straight line motion on the driving test desk. The rotary motion servo driver is connected with a second servo motor which does the rotary motion on the driving test desk. The displacement sensor is used to detect the displacement of a contact wheel which maintains contact with the heterotypic glass gabarit. The device utilizes the contact wheel to collect the information of the glass gabarit, considers the motion states of the test desk and the contact wheel, combines the real time positions of sampling points gained from the rotary motion and straight line motion, calculates and fits the data in computer, and gets the gabarit curve of the heterotypic glass. The device does not need template, takes up small space, has simple structure and low cost, and is convenient to be used.

Description

technical field [0001] The present invention relates to a contact type special-shaped glass profile detection device and method, more specifically a device and method based on rotation-linear motion, data sampling in polar coordinates and data fitting in rectangular coordinates, aimed at the profile of large special-shaped glass Detection device and method. Background technique [0002] At present, contact measurement is widely used in the detection of special-shaped curve contours, such as the detection of the frame contour in the edging of spectacle lenses. The scanning probe of the scanner is used to perform three-dimensional scanning of the full frame frame. Under the control of the microcomputer Carry out data calculation to obtain the shape data of the frame, but this method has a small detection range and is only suitable for small craft products such as frames, not for the detection of large flat pieces. [0003] The equipment that can be found on the market that ca...
