Description
Technical field
The present invention relates to a kind of rotating shaft limit device and limit method thereof, relate in particular to and a kind ofly can realize main shaft electronic limit for the anglec of rotation in rotation process, is a kind of rotating shaft limit device and limit method thereof of belt sensor.
Background technology
In the frame for movement of some rotations, the position of its rotation needs to control, and due to the impact of gas circuit and cable, main shaft is not done unlimited rotary, but actuating range but needs to cover 360 degree.Software dictates for example, motor rotating range+/-180 degree, but when the software operation error, or motor desynchronizing, motor may exceed rotating range, therefore needs a device to come the anglec of rotation of limiting motor.
In rotary head type aluminum steel press welder, the rotation of nation's head still when motor desynchronizing, needs motor stop immediately and report to the police because the impact that is subjected to cable can not be made unlimited rotary.
Once adopted in drive mechanism in traditional rotary head type bonding equipment, and used a driving shaft to drag two driven shafts, these of two driven shafts are the rotating shafts of need controlling, and another one is to be used for specially the rotating shaft of spacing detection.By different gearratios, to realize the spacing control to the rotating shaft of main shaft.
The shortcoming of above design:
1. be that the rotating part rotary inertia strengthens owing to having added a power transmission shaft;
2. whole part quality increases, and design is compact not, can't re-use other parts and drag this parts;
3. cost is higher.
Summary of the invention
The present invention is directed to above-mentioned problems and correct, make product structure simple, compact to design, cost is low.
The present invention uses one group of sensor to coordinate a logic circuit to realize spacing to the main shaft rotation.When motor exceeded rotating range, logic circuit can be given signal of motion controller, and motion controller stops and reports to the police.
Concrete technical scheme is:
A kind of rotating shaft limit device of belt sensor, it comprises spacing flagpole, limit sensors and the logic circuit that is connected with limit sensors, described spacing flagpole is anchored on rotating shaft, described limit sensors is fixed on around rotating shaft, when described spacing flagpole rotated to described limit sensors correspondence position, it enough covered the sensing points of described limit sensors; Described logic circuit connects the motion controller of controlling rotating shaft.
Described limit sensors is three adjacent limit sensors, described three limit sensors, and between the sensing points of every adjacent two limit sensors, distance is less than the width of described spacing flagpole; Do not have two adjacent limit sensors sensing points between distance greater than the width of described spacing flagpole.
The angle that described spacing angle equals to form between the initial position of described centre position limit sensors sensing points and described spacing flagpole and rotating shaft axle center adds the angle that forms between the above centre position limit sensors sensing points and adjacent limit sensors sensing points and rotating shaft axle center.By the angle of installation of sensors and the width of spacing flagpole, can adjust spacing angle.
The sensor sensing points that in described limit sensors, the position mediates and the initial position of described spacing flagpole and rotating shaft axle center are positioned at same straight line.This kind situation is applied in the situation that surpasses 180 degree rotations more.
It comprises the playback flagpole, and described playback flagpole corresponding position is fixed with the playback sensor.This kind structure can make main shaft get back to original position.
A kind of limit method of rotating shaft limit device of above-mentioned belt sensor, described logic circuit triggers by following rule:
Described spacing flagpole is when start bit, and described limit sensors state and flag bit state are sky;
When described spacing flagpole covers described realizing middle limiting sensor and clockwise previous limit sensors thereof simultaneously, Returning mark position state is clockwise status signal;
When described spacing flagpole covers described realizing middle limiting sensor and a clockwise rear limit sensors thereof simultaneously, Returning mark position state is counterclockwise status signal;
