Jig Table Delivery Suction for Secure Workpiece Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing apparatuses face challenges in securely delivering small or specially shaped workpieces without dislodgment, and their complexity and size are increased by the need for complex suction and clamp mechanisms.
Innovation Solution
A processing apparatus featuring a jig table with dual suction channels and a delivery assembly that includes grippers and a suction pipe, allowing for secure negative pressure application and positioning to prevent workpiece dislodgment during delivery, while maintaining a simplified structure through a link mechanism and check valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If actuators are added to position the suction mechanism and clamp mechanism in operational and retracted positions, then the mechanisms can be precisely controlled, but the processing apparatus becomes complex in structure and large in size and weight
Solution Approach 1:
The suction mechanism and clamp mechanism are merged into an integrated delivery mechanism. By combining these functions into a single mechanism, the need for separate actuators for each mechanism is eliminated, reducing the overall number of actuators required and simplifying the apparatus structure while maintaining precise positioning control.
Solution Approach 2:
The delivery mechanism is designed with multi-functionality, serving both as a clamp mechanism for securing the jig table and as a suction mechanism for holding the workpiece. This universal mechanism performs multiple functions simultaneously, reducing the need for separate dedicated mechanisms and actuators for each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively prevents workpiece dislodgment during delivery and maintains a non-complex structure by ensuring consistent suction force and controlled movement of the jig table, enhancing processing reliability and efficiency.
Implementation Method 1
a suction mechanism for keeping a negative pressure in the jig table for attracting the workpiece under suction to a holding surface of the jig table
Implementation Method 2
a delivery assembly for delivering the jig table from the temporary rest area onto the table base while applying a negative pressure to the second suction channel of the jig table

AI summary
A processing apparatus includes a table base to which a jig table is removably secured, a cutting unit, a moving assembly for moving the table base between a processing area and a mounting/dismounting area, and a delivery assembly for delivering the jig table from a temporary rest area onto the table base while applying a negative pressure to a second suction channel of the jig table. The delivery assembly includes a pair of grippers for gripping both sides of the jig table, a suction pipe connected to the second suction channel of the jig table that is gripped by the grippers, and a lifting and lowering unit for positioning the suction pipe selectively in an operative position where the suction pipe is connected to the second suction channel and a lifted position where the suction pipe is spaced from the second suction channel.
