Problems solved by technology

[0005] However, the measurement robot for performing the inspection repeatedly performs measurement at a predetermined position, so when there is distribution (scattering) in the stop positions of the above-mentioned trolley base, the values ​​measured by the measurement robot are also cumulatively distributed, so accurate inspection cannot be obtained result

Abstract

A truck for examination of a vehicle body includes a moving module configured to move truck bases with a vehicle body fixed thereto, a sensor module configured to be moved by the moving module and to measure stop position distribution of the truck base that reaches a predetermined position, and a calibration module configured to adjust a position of the truck base based on the measured distribution. The examination truck may enhance reliability of measurement result of assembly precision in a system for measuring the assembly precision of the vehicle body in a vehicle body assembly line.

Description

technical field [0001] The present invention relates to a trolley for inspecting vehicle bodies, and more particularly to the following calibration trolley and calibration method thereof, which are used for calibrating the position of the trolley on which the vehicle body is fixed, so as to improve the use in measuring the vehicle body assembly line. The reliability of the measurement results of the assembly accuracy in the body assembly accuracy system. Background technique [0002] On the automobile assembly line, various parts are joined to the body B by means of an automated process such as welding. In addition, as a result of the assembly process, the means for checking whether the components are properly soldered to the intended location are also automated. [0003] figure 1 It is a perspective view of a conventional truck structure. refer to figure 1 , a conventional trolley is configured in such a way that the trolley base 16 is placed on the trolley track 10 and...
