[0002] Currently, in the actuators of handling robots and logistics robots, for fixed swing execution, servos composed of reducers, motors, encoders and drivers are used. However, they are large in size, short in life, have many problems in use and are costly.

[0003] In order to increase the service life of the actuators of handling robots and logistics robots, reduce the structural volume, make them simpler to use, and further reduce the cost, it is necessary to use a more direct and efficient design solution as the actuator. Utility Model Content

[0004] Based on the above and the deficiencies of the existing structures, the utility model provides a fork lever mechanism based on a rotating magnet to solve the above problems of short service life, large size, many usage problems and high cost.

[0005] The technical solution adopted by the utility model is as follows:

[0007] The lever mounting hole (111) of the lever (11) is square and is provided with a lever stopper opening (112) that cooperates with the blocking module (13); the blocking module (13) is covered with a rubber shock-absorbing ring (131);

[0008] The rotor shaft (21) of the rotating magnet (2) has a rotor output end (211) of a square structure; the front mounting end cover (22), the stator module (24) and the rear end cover (26) are all processed with threading grooves (221) at four corners for convenient threading; the four surfaces of the front mounting end cover (22) are all processed with threaded mounting holes (222) for installation; the stator module (24) has two stator windings (241) connected in series; and the driving module (25) is installed with a Hall chip (251);

[0009] The working principle is that the driving module (25) is powered on through the connector (252), and after receiving the rotation signal, the stator winding (241) on the stator module (24) is charged to generate a magnetic field, driving the rotor magnet (23) and its mounting carrier rotor shaft (21) to rotate, and the rotor shaft rotates through the rotor output end (211) in cooperation with the square lever mounting hole (111) of the lever (11); when the lever (11) rotates 90 degrees, the blocking module (13) and the lever stopper (112) of the lever (11) cooperate to precisely control the rotation angle at 90 degrees; the driving module (25) adjusts the current direction to reverse the magnetic field of the stator module (24), and drives the rotor shaft (21), the rotor magnet (23) and the lever (11) to reset in the reverse direction;

[0010] The lever (11) in the lever mechanism (1) can be installed in a reverse mirror image, so as to achieve a swinging motion in the mirror image direction;

[0011] The driving module (25) obtains the current position state of the rotor magnet (23) through the Hall chip (251) installed thereon;

[0012] The rotation signal received by the drive module (25) supports at least one of an IO switch signal, an RS485 bus signal, a CAN bus signal, and a carrier bus signal.

[0013] Compared with the traditional combination of reducer, brushless motor, encoder and driver, the utility model removes the reducer and encoder, and replaces the brushless motor with a rotating magnet, thereby increasing the service life, reducing the volume, simplifying the structure, improving the execution efficiency and reducing the overall cost.
