OG exemplary drawing
 
1. A measuring and drawing device, comprising:
a supporting frame,
a rotation driving portion,
a reciprocation driving portion,
a drawing member,
a first laser generator,
a second laser generator,
a distance measuring sensor,
an angle sensor, and
a control module, wherein:
the rotation driving portion comprises a first motor and a rotating arm,
the first motor is disposed on the supporting frame,
the first motor is configured to drive the rotating arm to rotate relative to the supporting frame,
the reciprocation driving portion is disposed on the rotating arm and comprises a second motor and a belt gear pair,
the second motor is operatively coupled to a gear belt of the belt gear pair,
the drawing member is disposed on the gear belt and is configured to reciprocate along a length direction of the rotating arm,
a drawing point of the drawing member is retractable,
the first laser generator is disposed at a center of an axis of an output shaft of the first motor,
the second laser generator is disposed on the drawing member,
the distance measuring sensor is fixedly disposed relative to the output shaft of the first motor and is configured to measure a distance between the output shaft of the first motor and the drawing member,
the angle sensor comprises an emitter and a receiver,
the emitter is disposed on the rotating arm,
the receiver is fixedly disposed relative to the output shaft of the first motor and is configured to sense a rotating angle of the rotating arm,
each of the distance measuring sensor and the angle sensor is connected to the control module,
the control module is connected to and is configured to control each of the first motor, the second motor, the first laser generator, and the second laser generator,
the control module is configured to control the drawing point of the drawing member to extend out of or retract back into the drawing member through an electromagnet,
the control module is configured to control each of the first laser generator and the second laser generator to emit a light spot and control the first motor and second motor to work, and
when a position of the light spot of the second laser generator is confirmed:
the measuring and drawing device is configured to perform distance measuring through the distance measuring sensor and perform angle sensing through the angle sensor, and
the drawing point of the drawing member is configured to be controlled to extend out of the drawing member to perform drawing of a straight line and a curve.
