Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a stepping motor transfer device. Background Art

[0002] The transplanting device of a stepper motor is a device that combines stepper motor technology with transplanting functions. A stepper motor, also known as a pulse motor, is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Its working principle is based on the fact that each time an electrical pulse signal is received, the rotor of the motor will accurately rotate a fixed angle (step angle) or move forward a fixed distance. The output displacement (angular displacement or linear displacement) is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. In the transplanting device, the stepper motor is usually used as a driving component, and through its precise displacement and speed control, it can achieve precise movement of the transplanting mechanism. For example, in a plant transplanting device used for garden maintenance, the stepper motor can drive the load-bearing platform or support plate to move precisely, thereby controlling the position and speed of the transplanting mechanism to ensure that the object is accurately and efficiently transplanted to the target position.

[0003] However, the transfer devices in the prior art are mostly assembled by splicing parts, and the assembly process lacks effective control. The assembled slider platform has low operating accuracy in clamping the workpiece. In addition, in the prior art, the entire transfer device can only achieve transfer in a single direction. When multi-stroke transfer is required, multiple single drive sources need to be set up for continuous operation. Therefore, it not only increases production costs, but also reduces the practicality of the transfer device to a certain extent. Utility Model Content
