Automatic measurement equipment for profile and position of logo mounting hole

Abstract

The invention relates to the field of measurement equipment, in particular to automatic measurement equipment for the profile and the position of a logo mounting hole. The automatic measurement equipment comprises a processing device as well as three precision servo motion platforms and five cameras which are controlled by the processing device, wherein a first precision servo motion platform drives a first camera and a second camera to perform shooting scanning on two long edges of a rectangular casing of a to-be-measured product, a second precision servo motion platform drives a third camera and a fourth camera to perform shooting scanning on two short edges of the rectangular casing of the to-be-measured product, a third precision servo motion platform drives a fifth camera and a second camera to perform shooting scanning on the logo mounting hole of the to-be-measured product, and the processing device can calculate the profile and the position of the logo mounting hole according to the measurement data provided by the five cameras. The automatic measurement equipment can be well applied to the application condition of batch product manufacture.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to a non-contact optical automatic measuring equipment. Background technique [0002] At this stage, the functional homogeneity of electronic products is relatively serious, which prompts consumers to pay more attention to the attractiveness of product appearance. Based on this, the design, processing and assembly of LOGO (logo), which is an important part of the product appearance, must be refined to meet the increasingly high aesthetic requirements of consumers. [0003] An existing electronic product made of metal has a rectangular housing, on which a LOGO mounting hole is arranged, and the LOGO mounting hole is divided into upper and lower parts, located in the middle of the rectangular housing. Since the shape of the installation hole of the LOGO is a complex curve shape, in order to ensure the qualified processing quality, it is necessary to measure the contour and position...

Problems solved by technology

For example, as a general-purpose measuring device, an optical three-coordinate measuring instrument can realize the above-mentioned measurement with custom-made fixtures and light sources, but its cost is high; in addition, it has high requirements for the use environment: air cleanliness, noise, temperature, etc. It is not suitable for use in ordinary production workshop environments; moreover, it is generally equipped with only one measuring head, which can only scan and measure step by step, with low efficiency and cannot meet the needs of rapid production

It can be seen that the optical three-coordinate measuring instrument is not well suited for the application of batch manufacturing of products
