Dip Coating Fastening Device with Rocker Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for immersion treatment of vehicle bodies, such as cataphoretic dip painting, require a high height position for non-immersed objects on turning stations due to rigid skids and long links, which is undesirable for upstream and downstream transport systems.
Innovation Solution
A fastening device with U or V-shaped rockers that allow the object to move relative to the skid under gravity or active drive, reducing the height of the non-immersed position and providing stability in both immersed and non-immersed states through guided pins and slots, with an optional damping device to control movement speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid skids with long links are used to connect the turning axis to the vehicle bodies, then the vehicle bodies can be reliably positioned during rotation, but the height of non-immersed objects on the turning station becomes excessively high
Solution Approach 1:
The patent applies dynamics by replacing rigid skids with a dynamic suspension system using rockers and links that can pivot and adjust their position. The rockers (13) connected to the basic structure (20) via pivot pins (14) allow the vehicle body (3) to move relative to the skid during rotation, enabling the system to adapt its height dynamically while maintaining positioning reliability throughout the rotation process.
2Adaptability or versatility
If the axis of rotation is positioned outside the treatment liquid to enable 180° rotation, then the vehicle bodies can be fully immersed, but the height of the vehicle bodies within the turning station becomes relatively large
Solution Approach 1:
The patent applies dimensionality change by introducing vertical movement capability through the rocker mechanism. Instead of maintaining a fixed horizontal rotation plane, the system allows vertical displacement of the vehicle body during rotation via the pivoting rockers (13) and links (18), enabling the axis of rotation to remain outside the treatment liquid while minimizing the height of non-immersed positions.
3Device complexity
If conventional rigid skids are used to fasten vehicle bodies, then the structure is simple and stable, but the system cannot accommodate the required height reduction for efficient transport
Solution Approach 1:
The patent applies segmentation by dividing the rigid skid into multiple independent components: the basic structure (20), rockers (13), links (18), and pivot pins (14). This segmentation allows each component to perform its specific function while collectively achieving the height reduction goal, maintaining relative simplicity through modular design.
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 solution minimizes the height of non-immersed objects, ensuring a stable resting position and reducing the distance from the skid and axis of rotation, allowing for efficient and stable transport through the system with reduced vertical displacement during rotation.
Implementation Method 1
the object is given the freedom to move in a very defined way relative to the basic structure of the skid under the influence of gravity
Implementation Method 2
both legs of the U or V have a slot into which a guide pin fastened to the skid engages and slides in the corresponding slot when the skid rotates

AI summary
There is described an installation (1) for dip coating articles (3), in particular vehicle bodies, which are movable up to and away from at least one dip tank (2) with the aid of a transport system (4). In order to be dipped and removed, they are moved onto a rotary platform (16) of at least one stationary rotary station (5, 6) and are dipped into and removed from the treatment liquid by rotation of the rotary platform (16). Each article (3) is fastened with the aid of a fastening device (11) to a skid (7) which interacts with the transport system (4). The fastening device (11) has a holding structure (12) for the article (3) and at least two rockers (13) which are U- or V-shaped and are fastened in a pivotable manner to the holding structure (12) at their vertex. The two arms of the U or V have a slot (15) into which in each case one guide pin (16, 17) fastened to the skid (7) engages and slides in the corresponding slot (15) upon rotation of the skid (7). In this way, the article (3) is at a shorter distance from the rotary platform (16) in the removed position than in the dipped position.
