PROBLEM TO BE SOLVED: To provide a position monitoring system capable of accurately measuring the position of a lift-up structure. SOLUTION: This position monitoring system comprises a scale 115 for height measuring and a camera 113 that displace relatively vertically in response to lifting of the lift-up structure 1 along a guide column 11. The scale 115 for height measuring has a template image showing a vertical direction position and extends in the vertical direction. The camera 113 photographs the scale 115 for height measuring. The position monitoring system has a computer for calculating the vertical direction position of the lift-up structure 1 based on the position of the template image in the image photographed by the camera 113.

Position monitoring system, and position monitoring method

The invention discloses an automatic optical detector. The automatic optical detector comprises a carrier bottom plate, a CCD (charge coupled device) module, a product fixing module, an electric control box module and a display. The CCD module and the product fixing module are arranged on the carrier bottom plate and located on the same center axis. The electric control box module is arranged on the carrier bottom plate and electrically connected with the CCD module and the display, the electric control box module comprises an insulating box body, a power switch and fans, and the fans are symmetrically arranged on two sides of the insulting box to form a heat radiation air passage. The automatic optical detector has the advantages that a to-be-detected product is fast, efficiently and preliminarily fixed by using the product fixing module, high-precision deviation control is realized through a finely-tunable pin, structural simplicity and convenience in operation are realized, and quick, stable and high-precision product parallelism and perpendicularity detection is realized.

PURPOSE:To easily and accurately measure actual moving quantities of X and Y tables in both X and Y directions by providing reference points having optical characteristics different from those of the surrounding area in the X and Y direction on the main surface of a plate in parallel at a pitch interval. CONSTITUTION:When a controller 1 outputs the number of pulses proportional to quantities, by which X and Y tables 6 and 7 are to be moved, to pulse motors 8 and 9 for driving an X-Y direction moving device 5, the tables 6 and 7 are moved by the quantities proportional to the number of pulses. However, the movement commanding values do not necessarily coincide with the actual moving quantities of the tables 6 and 7, since mechanical errors caused by the finishing error and assembling error of the device 5, fluctuation of loads applied to the motors 8and 9, and the differences between the commanding values and actual moving quantities exist as peculiar errors of each device. Therefore, a plate for measuring the moving quantities is positioned and fixed to the surface of the table 6 of the device 5 and the tables 6 and 7 are moved by outputting movement commanding values from the controller 11 while positions of reference points 3 are observed with a camera 10. Then, the difference between the calculated moving quantity found from the number of pulses and actual moving quantity of the reference points 3 is measured.
