Supplementary-light-adjustability type measuring system capable of measuring side surface or inside

Abstract

The invention discloses a supplementary-light-adjustability type measuring system capable of measuring a side surface or an inside. The measuring system comprises a control system, a work bench, a first guide rail assembly, a measuring assembly, an automatic feeding and blanking assembly, and at least one carrier assembly. The first guide rail assembly consists of a left support seat, a right support seat, and a first guide rail, wherein the left support seat and the right support seat are fixedly connected to the work bench. The measuring assembly can slide along the first guide rail in a reciprocating mode. The automatic feeding and blanking assembly is arranged above the work bench. The detection assembly is provided with at least one a light supplementing device with the adjustable light source height and radiation angle. The carrier assembly is provided with an optical deflector that is used for deflecting the light of the side surface or the internal structure of a to-be-measured object. The measuring assembly, the automatic feeding and blanking assembly, and the carrier assembly is connected to the control system electrically. According to the invention, the light supplementing angel and range can be adjusted; and the measurement precision of the side surface and the internal structure of the complicated to-be-measured object with the small dimension structure can be improved. Moreover, the measurement success rate is improved, the measurement time is shortened; and the measurement efficiency is enhanced.

Description

technical field [0001] The invention relates to a non-contact visual imaging size measurement system, and more particularly relates to a measurement system with adjustable supplementary light and capable of measuring sides or interiors. Background technique [0002] The non-contact size measuring device is based on photoelectric, electromagnetic, ultrasonic and other technologies. When the measuring element of the instrument is not in contact with the surface of the measured object, various appearance or internal dimensional data characteristics of the measured object can be obtained. Compared with the traditional contact distance measuring system, the non-contact size measurement system has higher precision, more convenient operation, higher safety factor, high cleanliness, and less pollution to the measured object during the measurement process, so it is used in industrial Various fields of production and scientific research. [0003] Typical non-contact size measurement ...

Problems solved by technology

[0004] The visual imaging measurement system in the prior art has certain limitations for the measurement of the complex structure and shape of the surface and interior of the object to be measured: First, for small-sized objects with complex structures, the ambient light cannot be sufficient during the measurement process. Irradiating the surface of the object to be measured, especially the internal surface of the object to be measured, causes the camera to be under-exposed or over-exposed during the measurement process, resulting in poor imaging quality of the obtained image, resulting in the need for repeated measurements to obtain satisfactory measurement results. This undoubtedly greatly reduces the measurement efficiency and increases the measurement cost; thirdly, due to the complex structure of the small-sized DUT, it is difficult to clamp it on the carrier, or the clamping process takes too long, and the Or although the object to be measured is clamped, for example, the fixture and the carrier will block the ambient light, which will affect the imaging quality of the object to be measured; finally, measure the object to be measured with complex structures on the side and inside When the camera lens of the measurement component is larger than the object to be measured, the camera lens cannot fully penetrate into the side or inside of the object to be measured to take pictures, so that the side or inside of the small-sized object to be measured There is no more effective solution for size
