AI Technical Summary

Technical Problem

In existing 3D printing technologies, the process of fixing and removing the dental mold tray on the printing platform can easily cause the printing platform to deviate beyond the reasonable range, affecting the printing accuracy and quality of the dental mold. Especially when using a robotic arm, the instantaneous impact between the tray and the printing platform makes the deviation difficult to control.

Method used

A deviation detection device is used to detect the deviation of the printing platform. The placement order and force of the trays are controlled by the force application device and the control device to ensure that the trays are stably positioned on the printing platform and reduce instantaneous impact. Electromagnets and magnetic components are used to achieve precise positioning and fixation of the trays.

Benefits of technology

Effective control of the printing platform deviation during tray placement within a reasonable range ensures the accuracy and quality of dental mold printing, thereby improving the automation efficiency and product qualification rate of dental mold production.

Abstract

This invention discloses a system and method for controlling the placement of a 3D printing tray for dental models, belonging to the field of dental instrument manufacturing technology. The system includes a deviation detection device, a force application device, and a control device. The deviation detection device detects a deviation at a first position on the printing platform; the force application device applies a control force to a second position on the tray corresponding to the first position; and the control device controls the sequence and magnitude of the control force applied by the force application device to the second position on the tray based on the deviation value at the first position. The method is implemented based on the corresponding system. The control device of this invention controls how the force application device applies control force to the tray based on the deviation value of the printing platform detected by the deviation detection device, thereby reducing the instantaneous impact of the tray on the printing platform. This ensures that after the tray is installed on the printing platform, the deviation of the printing platform is within the required range, guaranteeing the quality of the dental model printing.
