Pickup Tooling With Flippable Unit for Workpiece Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pickup tooling has poor compatibility with workpiece postures, unable to stably grip workpieces with varying poses, limiting its applicability.
Innovation Solution
A pickup tooling with a flippable pickup unit driven by a mechanism that rotates about a central axis, allowing it to adjust its posture to accommodate different workpiece orientations, along with position-limit mechanisms to prevent excessive flipping and ensure accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pickup tooling uses a fixed gripping structure, then the structure is simple and easy to manufacture, but it can only pick up workpieces with a specific pose, resulting in poor compatibility
Solution Approach 1:
The pickup unit is designed to be rotatable relative to the mounting seat around a central axis, transforming the fixed gripping structure into a dynamic one. The driving mechanism actuates the pickup unit to rotate to different postures, enabling it to adapt to workpieces with different poses. This dynamic configuration resolves the contradiction by allowing the structure to change its orientation while maintaining relative simplicity through modular design.
Solution Approach 2:
The pickup unit serves multiple functions by rotating to different postures - it can grip workpieces in various orientations (e.g., horizontal, vertical, inclined positions). This multi-functionality is achieved through the rotatable connection between the pickup unit and mounting seat, allowing a single gripping structure to handle diverse workpiece poses without requiring multiple dedicated grippers.
2Adaptability or versatility
If the pickup unit is made flippable to handle different workpiece postures, then the adaptability improves, but the risk of damage due to excessive flipping increases
Solution Approach 1:
The position-limit mechanism is designed to prevent excessive flipping of the pickup unit before damage can occur. The limiting components are pre-positioned to stop the pickup unit at safe angular positions, counteracting the tendency toward over-rotation that could cause damage. This preliminary protective measure resolves the contradiction by enabling full rotational adaptability while pre-preventing the harmful extreme positions.
3Adaptability or versatility
If the pickup unit can rotate freely to any position, then the flexibility to handle various workpiece orientations is improved, but the positioning precision and stability decrease
Solution Approach 1:
The position-limit mechanism pre-establishes specific stopping positions for the pickup unit during its rotation. These predetermined positions correspond to standard workpiece orientations needed for picking operations. By providing pre-defined stable positions, the mechanism enables the pickup unit to achieve both flexibility in handling various orientations and precision at each stopping point, resolving the contradiction between free rotation and positioning accuracy.

AI summary
Embodiments of the present application provide a pickup tooling, which relate to the field of pickup devices. The pickup tooling includes a base and a pickup mechanism. A mounting portion is arranged on one side of the base in a first direction, and the mounting portion is used for connecting an execution end of the robot. The pickup mechanism includes a mounting seat, a pickup unit, and a driving mechanism. The mounting seat is connected to the base, and the pickup unit is connected to the mounting seat in a flippable manner and is used for picking up a workpiece. The driving mechanism is configured to drive the pickup unit to rotate about a central axis to change the posture of the pickup unit, with the central axis perpendicular to the first direction. The pickup unit is flippable about the central axis and connected to the mounting seat.
