Wireless 3D auto-offset system for robot arms
View Patent ↗A wireless 3D auto-offset system for robot arms is provided. The wireless 3D auto-offset monitor sensor of the system includes an electronic leveling sensor, a Z-axis optical scale, and an XY-axes CCD monitor sensor for monitor and judgment of level states, offsets, and gaps, respectively.
1. A wireless 3D auto-offset system for robot arms, comprising:
a wireless 3D offset monitoring sensor, comprising
an electronic tilt detector comprising an arcuate body, the interior thereof filled with liquid material and having a bubble; and
a sensor, sensing positions of the bubble; and
a corrector, retrieving and displaying the bubble positions using the sensor on a screen thereof, determining whether a process apparatus is horizontally located according to a predefined standard range, and, if not, calculating an offset value of the process apparatus.
2. The wireless 3D auto-offset system for robot arms as claimed in claim 1 , wherein the sensor is a CCD sensor, detecting three-dimensional (3D) positions of the bubble.
3. The wireless 3D auto-offset system for robot arms as claimed in claim 1 , wherein the process apparatus is a pair of pincettes of a robot arm, pins of a three-pin process plate, and a process plate.
4. A wireless 3D auto-offset system for robot arms, comprising:
a three-pin process plate having three pins;
a wireless 3D offset monitoring sensor, comprising an optical scale and installed above the three-pin process plate, wherein the optical scale is a dual optical scale in which one optical scale serves as a transmitter to transmit a parallel beam of light and the other optical scale serves as a receiver to receive the parallel beam of light; and
a corrector, retrieving an obstructive state of receiving the parallel beam of light from the wireless 3D offset monitoring sensor, displaying light signals on a screen thereof, and determining whether a Z-axis gap size of each pin of the three-pin process plate exceeds a threshold value.
5. The wireless 3D auto-offset system for robot arms as claimed in claim 4 , further comprising a pair of pincettes of a robot arm, clipping the wireless 3D offset monitoring sensor to move forward and backward, enabling the dual optical scale to pass through each pin of the three-pin process plate.
6. A wireless 3D auto-offset system for robot arms, comprising:
a process plate having a center mark;
a wireless 3D offset monitoring sensor, installed above the three-pin process plate and comprising a sensor provided with a criterion mark, wherein the sensor compares a center position of the center mark with a center position of the criterion mark; and
a corrector, retrieving relative position information according to the center positions of the center mark and the criterion mark, determining whether an offset is detected according to the relative position information, and, if so, calculating an offset value.
7. The wireless 3D auto-offset system for robot arms as claimed in claim 6 , wherein the sensor is an XY-axes CCD monitor sensor.
