Description

technical field

[0001] The invention relates to a rotating shaft limiting device and a limiting method thereof, in particular to an electronic limiting device capable of realizing the rotation angle of the main shaft during rotation, and is a rotating shaft limiting device with a sensor and its limiting method. method. Background technique

[0002] In some rotating mechanical structures, the position of the rotation needs to be controlled, and due to the influence of the air circuit and cables, the spindle does not rotate infinitely, but the range of motion needs to cover 360 degrees. For example, the software stipulates that the rotation range of the motor is + / -180 degrees, but when the software operation is wrong or the motor is out of step, the motor may exceed the rotation range, so a device is needed to limit the rotation angle of the motor.

[0003] In the rotary head type aluminum wire bonding machine, the rotation of the head cannot be infinitely rotated due to the...

Embodiment Construction

[0033] The present invention is described by examples below, and it should be noted that the examples listed should not be construed as limiting the invention.

[0034] As shown in the figure: this embodiment is a rotating shaft limit device with a sensor, which includes a limit flagpole 2, a limit sensor 1 and a logic circuit connected to the limit sensor, and the limit flagpole 2 is fastened to the rotating shaft axis, the limit sensor 1 is fixed around the rotation axis, and when the limit flagpole 2 is rotated to the corresponding position of the limit sensor 1, it is enough to cover the sensing point of the limit sensor 1; the logic The circuit is connected to the motion controller that controls the rotary axis.

[0035] The limit sensor is three adjacent limit sensors 1, the three limit sensors 1, the distance between the sensing points of every two adjacent limit sensors 1 is smaller than the limit flagpole 2 The distance between the sensing points of two adjacent limi...
