Robot Head With Integrated Clip Loader for Precise Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting systems for vehicles, particularly in the automotive industry, face inefficiencies in assembly time and precision due to misalignment and deformation of functional parts, leading to increased effort and potential failure in engaging components with engagement zones.
Innovation Solution
A robot head with a component loader and mounting member that includes a storage rail, drawer, and compensation devices to ensure precise alignment and continuous assembly flow, allowing components to be quickly mounted without resupplying the robot head and accommodating design tolerances and deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a robot picks up components from an external magazine and positions them on engagement zones, then component mounting can be automated, but assembly time increases due to round trips between magazine and part
Solution Approach 1:
The robot head is designed with integrated component storage capability, allowing it to function both as the mounting tool and as the component supply source. This multi-functionality eliminates the need for separate magazine and robot head, removing round trip time while maintaining automated mounting capability
Solution Approach 2:
The component storage function is merged directly into the robot head structure. The storage rail and drawer mechanism are integrated within the robot head, combining component supply and mounting operations into a single unified device, thereby eliminating transportation time between separate components
2Productivity
If a percussion system pushes components to engage them on engagement zones, then component mounting can be achieved, but positioning precision is compromised due to misalignment and deformation
Solution Approach 1:
The percussion pushing system is replaced with a controlled linear movement mechanism. The robot head moves linearly along a second axis to push the component into the engagement zone, providing precise positional control and eliminating the misalignment issues associated with percussion systems
Solution Approach 2:
The engagement method changes from forceful percussion to controlled linear motion. By changing the movement parameter from impact-based to steady linear push, the system achieves both high engagement rates and precise positioning, accommodating part deformation and misalignment
3Manufacturing precision
If the robot head is released from the engagement zone to disengage the component body, then component mounting is completed, but assembly time increases due to release and repositioning operations
Solution Approach 1:
The component head is pre-positioned in the receiving zone of the robot head before the mounting operation begins. This preliminary positioning ensures that when the linear push occurs, the component is already correctly aligned, eliminating the need for post-engagement release and repositioning operations

AI summary
The invention relates to a robot head (1) for mounting components (2) comprising a head (10) configured to be engaged in a notch (5, 8) of an engagement zone (4, 7) of a part and a body (9) configured to be engaged in a support during subsequent stapling onto this support, the head (10) and the body (9) extending along a first axis (X1).The robot head (1) includes a component loader (12) comprising a storage rail (14) configured to receive the heads (10) of a plurality of components (2) arranged one after the other. The loader (12) includes a drawer (17) configured to extract the components (2) one by one from the storage rail (14) and convey the extracted component (2b) to a mounting element (13) comprising a receiving zone (40) for the extracted component (2b). This element allows the extracted component (2b), placed in the receiving zone (40, 92, 93), to be pushed forward by the robot head (1) along a second axis, until the head (10) of said extracted component (2b) enters a notch (5, 8) in an engagement zone (4, 7) of the part (3). The second axis is perpendicular to the first axis (X1) of the component. extract placed in the reception area.
