Example Embodiment

[0033] The present invention will be described below by means of examples, and it should be noted that the enumerated examples should not be construed to limit the invention.

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

[0035] The limit sensors are three adjacent limit sensors 1 , and the distance between the sensing points of each of the three adjacent limit sensors 1 is smaller than the limit flagpole 2 . The distance between the sensing points of no two ...

Abstract

The invention relates to a rotating shaft position-limiting device with a sensor and a position-limiting method thereof. The rotating shaft position-limiting device with the sensor comprises a position-limiting flag post, a position-limiting sensor and a logic circuit connected with the position-limiting sensor; the position-limiting flag post is tightly fixed at a rotating shaft; the position-limiting sensor is fixed around the rotating shaft, and the position-limiting flag post can sufficiently shade the sensing point of the position-limiting sensor when rotating to the corresponding position of the position-limiting sensor; and the logic circuit is connected with a motion controller controlling the rotating shaft. The invention has compact design of rotating parts and light weight, canbe easily carried on other motion parts, and has low cost.

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...
