Collision defensive measure that use Gantry distance measuring equipment and this

摘要

anti-collision method using the distance between the measuring apparatus and the gantry of the present invention, a pair of Y-axis gantry installed at both sides of the longitudinal direction and a head with a pair of X-axis gantry is installed; The side provided at both sides of the longitudinal direction of the gantry, and the X-axis, the distance measuring device is irradiated with light on both sides of the bottom wall of the other X-axis gantry for detecting the irradiation angle; And a control unit to maintain the minimum distance for the distance measurement to calculate the distance from the light irradiation height and the irradiated angle of the detection device, a pair of the X-axis gantry between the anti-collision to compensate for the distance errors of the X-axis gantry opposite sides; . and a ; In addition, the distance measuring device positioned on each side of the one longitudinal X-axis gantry is comprising: a first step of irradiating light to both the bottom wall of the other X-axis gantry; A second step of detecting each of the light irradiation angle of the distance measuring device on both sides; A third step of calculating a distance between both sides is applied to the detected X-axis gantry beam angle and the height of the laser light irradiated to the control point; And when the distance between the X-axis gantry is changed, the fourth step of compensating for at least the distance for the collision avoidance between the two sides the X-axis gantry distance error value; and a ; to the invention. According to, the longitudinal direction is provided on both sides of one X-axis gantry by measuring the distance to the other side of the X-axis gantry with a distance measuring device for irradiating light, it is possible to increase the measurement accuracy of the distance between the X-axis gantry, a pair of X-axis the minimum distance between the gantry has the advantage of always be kept constant to avoid collision. ; long-component room, the gantry, the laser pointer, distance measurement, compensation, trigonometry
