Application of servo in shuttle fork dialing motor

Shuttle car is widely used in warehousing and logistics equipment, and there are two main forms in warehousing and logistics equipment: shuttle-type warehousing system and shuttle type-warehousing system, and in the past, the trolley running on a fixed track transports goods to a designated place or connecting equipment. Equipped with intelligent sensing system, can automatically remember the origin position, automatic deceleration system. The main function is to realize tasks such as pickup, delivery, placement, etc.

Relying on the interpolation extension, the front end of the inner fork is installed and the lever on the motor realizes the push into the carriage, the traditional fork lever mechanism, comprising: a bracket fixed on the outer end of the inner fork of the shuttle fork, a DC motor mounted on the bracket, a lever located at the front end of the bracket and connected to the DC motor drive, a circuit board mounted on the front end of the bracket and a magnet installed at the end of the lever, and a single-chip microcomputer, a power module, a Hall sensor I, a Hall sensor II and a DC motor drive module are provided on the circuit board. After the lever is in place, the feedback signal is passed through Hall sensor I and Hall sensor II. This design is more complex in structure, involving many single materials, many assembly links, difficult to route, if a single piece has a problem, it takes a lot of energy to troubleshoot and repair treatment.

The second generation of shuttle fork lever servo is applied to the outer end of the shuttle fork inner fork swing, according to Feetech, servo and lever are connected to the rigid transmission mechanism, the role of the rigid transmission device is to bear the bending torsion torsion moment transmitted by the lever, to prevent the bending force directly applied to the output shaft of the servo to cause excessive damage to the servo, improve the reliability of use. It avoids the difficulty of wiring caused by the deflection of the traditional motor drive lever and the need for multiple cables to stop by the photoelectric switch control, and the cost increase caused by the installation of energy chains.

This servo + double bearing base + dial finger has the following characteristics: servo integration modularity - simple design, simple wiring, can realize 8 servos through a 4pin line in series to the 485 serial port of the PLC, support the 485 serial port protocol of the single-chip microcomputer and Modbus-RTU protocol. The servo internally adopts a magnetically encoded angle sensor, precise positioning, brushless motor, high life; Thickened all-steel gear, durable; Power-on automatically detects the current position and controls accurately; Simple installation, one-key setting of the median; Rigid transmission device, impact resistance, not afraid of jam card machine and other characteristics. The entire design of the servo is designed around the application scenario of the shuttle, and three versions have been applied and iterated, and the third version has been widely used with good stability and long life.
