Multi-mover direct drive transmission system

A multi-mover direct drive transmission system, comprising a plurality of stator units connected in sequence, a guide rail attached to the plurality of stator units, a plurality of mover units configured to form a sliding connection with the guide rail and form a drive force with the plurality of stator units, and a controller configured to control the plurality of mover units to move;

• wherein each of the plurality of stator units comprises a stator, a winding fixed to the stator, a photoelectric switch, a reading head, and a driver electrically connected to the controller, the guide rail is fixed to the stator, and the driver is electrically connected to the winding, the photoelectric switch, and the reading head, respectively;
• wherein each of the plurality of mover units comprises a mover, and a magnet fixed to the mover, a stopper fixed to the mover, and a grating ruler extending along a moving direction of each of the plurality of mover units;
• the mover forms a sliding connection with the guide rail, the magnet is spaced from and arranged opposite to the winding, and the winding is configured to drive the magnet to enable the each of the plurality of mover units along the guide rail;
• wherein the stopper is arranged opposite to the photoelectric switch, there are two stoppers, and positions of the two stoppers in the mover correspond to two opposite ends of the grating ruler along the moving direction of each of the plurality of mover units;
• each of the two stoppers are configured to pass and block the photoelectric switch, to enable the photoelectric switch to generate a zero signal and send the zero signal to the driver;
• wherein the grating ruler is arranged opposite to the reading head, and the reading head is configured to read information from the grating ruler in real-time and generate a reading signal according to the information and send the reading signal to the driver;
• wherein the controller is configured to obtain the reading signal and the zero signal from the photoelectric switch by the driver, to locate positions of the plurality of mover units in real-time.
