Movable Workpiece Positioning Platform for Mixed Plate Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece placement platforms struggle to accurately position small plate-shaped workpieces in the X-axis direction due to the absence of a corresponding positioning member, leading to inefficient use of the placement surface and difficulty in handling workpieces of varying sizes.
Innovation Solution
A workpiece placement platform device with a movable workpiece positioning member that can be adjusted and pivoted relative to the placement surface, allowing for sectioning of the surface to accommodate both large and small workpieces by providing X-axis and Y-axis direction positioning members that can be easily moved in and out, and adjusted in position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed X-axis reference member is provided on the placement platform, then large workpieces can be accurately positioned in the X-axis direction, but small workpieces cannot contact the reference member and thus cannot be accurately positioned in the X-axis direction
Solution Approach 1:
The patent applies the dynamics principle by making the X-axis reference member movable rather than fixed. The reference member can be moved along the X-axis to different positions and locked in place, allowing it to adapt to both large workpieces (when positioned at one location) and small workpieces (when positioned at another location). This dynamic positioning capability resolves the contradiction between maintaining positioning accuracy for large workpieces and adapting to smaller workpieces that cannot contact a fixed reference member.
2Measurement precision
If the placement surface is divided into multiple sections with positioning members for each section, then small workpieces can be accurately positioned, but the device complexity increases due to multiple positioning members
Solution Approach 1:
The patent applies the universality principle by designing a single X-axis reference member that can serve multiple functions and positions. Instead of providing separate positioning members for each section of the placement surface, one reference member is made movable along the X-axis, allowing it to be positioned where needed to accommodate workpieces of various sizes. This multi-functional approach reduces device complexity while maintaining positioning accuracy.
3Measurement precision
If heavy positioning members are used to ensure stability and accuracy, then positioning precision is improved, but the ease of operation decreases due to difficulty in moving and repositioning them
Solution Approach 1:
The patent applies the dynamics principle by incorporating a movable design with locking mechanism for the X-axis reference member. The member can be easily moved along the X-axis when the locking mechanism is released, and then securely locked into position when needed. This dynamic design with easy-to-operate locking/unlocking mechanism resolves the contradiction between maintaining positioning stability through a substantial reference member and enabling easy repositioning when needed.

AI summary
A workpiece placement platform device including: an X-axis direction positioning member provided on one side of a placement platform on which to place a plate-shaped workpiece and configured to position one side edge of the workpiece in an X-axis direction by contacting the one side edge; a Y-axis direction positioning member provided on another side of the placement platform and configured to position another side edge of the workpiece in a Y-axis direction by contacting the another side edge; and a workpiece positioning member that is movable in and out relative to a workpiece placement surface of the placement platform and configured to partition the workpiece placement surface into sections in the X-axis direction and enable simultaneous positioning at the sections on the workpiece placement surface.
