3D Printer Component Carrier Locking With Existing Motion Axes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printers require manual or robotic intervention for connecting and disconnecting the component carrier to/from the printer, which is inefficient and cumbersome.
Innovation Solution
Utilizes existing translational axes and motors in the 3D printer to couple and decouple the component carrier using a locking mechanism with a spring-loaded locking pin, eliminating the need for additional actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual or robotic systems are used to connect and disconnect the component carrier, then the component carrier can be firmly attached to the printer, but the operation becomes cumbersome and inefficient
Solution Approach 1:
The locking device automatically engages with the component carrier using the existing motor-driven translational axes. The coupling element with locking pin self-activates during the downward movement of the transport device, eliminating the need for manual lever mechanisms or additional robotic systems while ensuring reliable attachment.
2Extent of automation
If additional actuators or motors are added to automate the locking mechanism, then the attachment process becomes automated, but the device complexity increases
Solution Approach 1:
The existing motor-driven translational axes of the transport device are made multi-functional by integrating the locking mechanism into their motion path. The coupling element utilizes the downward movement of these existing axes to trigger automatic engagement, allowing the same motors to perform both transport and locking functions without requiring additional actuators.
Solution Approach 2:
The locking function is merged with the existing transport mechanism. The coupling element with its locking pin is integrated into the transport device's structure, combining the attachment function with the movement function that already exists in the system.
3Productivity
If a simple manual connection method is used, then the device complexity is low, but the productivity and operational efficiency decrease
Solution Approach 1:
The locking pin is pre-positioned on the coupling element such that it automatically engages with the component carrier during the downward movement of the transport device. This preliminary positioning ensures that the locking action occurs automatically as part of the transport sequence, improving productivity without requiring complex additional mechanisms.

AI summary
A 3D printer comprising a resin vat, a component carrier, a transport box for depositing the component carrier, a transport device for removing the component carrier from the transport box and transporting it into the resin vat, and for moving the component carrier downward and upward in the resin vat The transport device has translatory axes in the vertical and horizontal directions, each of which can be driven independently by a motor, the transport device having a locking device that detachably connects the component carrier. The locking device, during the downward movement along the vertical translatory axis, reaches a specific position (P) by the drive of the respective motor, at which a stop located on the vertical translatory axis sets a coupling element in motion. A spring-loaded locking pin arranged in contact with the coupling element is immersed in a bayonet opening of the component carrier by the movement. The immersed locking pin can be brought into a locking position in the bayonet opening via the horizontal translatory axis.
