Description

Full length and full width inspection device {FULL LENGTH AND FULL WIDTH INSPECTION DEVICE}

The present invention relates to a full length and full width inspection device.

Measurement of length is very basic in various technical fields. In fields such as geography measurement, aviation, and satellite, length in km is measured, and in general industries such as product production and construction, length in m is measured. Depending on the field, the length range to be measured also varies. According to the length range to be measured, the accuracy required in the field also varies accordingly.

In general, a device for measuring length and the like includes a measuring sensor, and in measuring the length and the like, it is classified into a contact type or a non-contact type inspection device according to whether or not such a sensor contacts an object to be tested.

Republic of Korea Patent Registration No. 10-1642952 (registered on July 20, 2016), a prior art non-contact inspection device, measures the length economically and efficiently by using an interferometer using two wavelengths of laser light in measuring the geometric length. It relates to a length measuring device using a two-wavelength laser interferometer that can maximize accuracy by minimizing errors at the same time.

As another non-contact inspection device, the prior art, Republic of Korea Patent Registration No. 10-1323383 (registered on October 24, 2013), measures the width, length, and height of the inspection object transferred through the transfer unit through a sensor and provides, It relates to an invention that minimizes the error range for values.

However, in the case of such a non-contact inspection device, inspection may be affected depending on the material of the inspection object, such as a foreign substance contained in the inspection object, shaking of the inspection object, or a material that reflects light, and the inspection environment is highly It has limitations that can guarantee accuracy only in controlled cases.

On the other hand, as a contact-type inspection device, the prior art is Republic of Korea Patent Registration No. 10-1714427 (registered on March 3, 2017) previously filed by the applicant of the present invention. The present prior art is to measure the overall length and width of the test object by contacting the sensor bar with the test object in a state where the test object is fixed. Compared to non-contact inspection devices, such a contact-type inspection device can reduce the deviation according to foreign substances and the material of the inspection object and improve accuracy.

However, such a contact-type inspection device has a disadvantage in that it is difficult to confirm exactly which point was measured because the inspection result is displayed only as a number, and it is difficult to grasp at a glance. In addition, when the inspection object is changed, it is difficult to inspect various inspection objects using one inspection device because the inspection device must be disassembled to change the resting table on which the inspection object is seated and other components.
