The encoder is connected to the drive motor 331 for communication, and the encoder is connected to the controller for communication.

[0064] Specifically, the controller can read the vehicle model information from the production system, and match the number of pulses sent by the controller according to the vehicle model information. The controller sends a control signal and a pulse signal to the driver, and the driver outputs the U, V, and W three-phase power supply voltage to the drive motor 331, and the drive motor 331 works to drive the screw 332 to rotate. Specifically, the encoder is set on the output shaft of the drive motor 331, and the encoder will feed back the rotation information of the motor to the driver. For example, for every rotation of the output shaft of the drive motor 331, the encoder will generate a certain number of pulses to the driver. The pulse signal output by the controller is used to determine the number of revolutions of the servo motor. In the driver, the pulse signal is compared with the pulse signal sent by the encoder. If the two are equal, it indicates that the number of revolutions of the drive motor 331 has reached the requirement. At this time, the driver controls the drive motor 331 to stop working, and the rear support plate 31 has moved to the target position.

[0065] The more pulses the controller sends, the more revolutions the drive motor 331 will rotate.

[0066] Optionally, the controller can be a PLC, a positioning module, an embedded motion control board, etc.
