Vacuum Coating Holder Pivot Bearing for Secure Article Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum coating systems face challenges in securely holding objects during the coating process, particularly due to the risk of holding devices being loosely attached or coming loose, which can lead to damage to other objects and inefficiencies in the coating process.
Innovation Solution
A device with a carrier and a pivot bearing system that includes a circumferentially closed and open receptacle design for the round body, allowing for secure insertion and rotation of the holding device, minimizing the risk of dislodgment and simplifying the insertion process through a computer-controlled handling device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a circumferentially closed receptacle with interference fit is used to secure the round body, then the holding device is securely fixed, but the insertion process becomes difficult and error-prone
Solution Approach 1:
The receptacle is divided into two distinct parts: a first circumferentially open receptacle for easy insertion and a second circumferentially closed receptacle for secure fixation. The round body transitions from the first receptacle to the second receptacle, combining the benefits of easy insertion with reliable fixation.
Solution Approach 2:
The first circumferentially open receptacle serves as an intermediary structure that facilitates the insertion of the round body into the second circumferentially closed receptacle. This intermediate step eliminates the difficulty of directly inserting into a closed receptacle while ensuring the final secure fixation.
2Reliability
If bearing pins are inserted into a closed receptacle with interference fit, then secure attachment is achieved, but careless work can result in incomplete insertion or detachment
Solution Approach 1:
The assembly process is segmented into two stages: first inserting the round body into the open receptacle (easy and error-tolerant), then transferring it to the closed receptacle (secure fixation). This segmentation reduces assembly errors while maintaining secure attachment.
Solution Approach 2:
The round body is preliminarily positioned in the first open receptacle before being transferred to the second closed receptacle. This preliminary positioning ensures proper alignment and reduces the risk of incomplete insertion or detachment during the final fixation stage.
3Reliability
If a single closed receptacle is used for the round body, then secure holding is achieved, but the insertion process is complex and time-consuming
Solution Approach 1:
The single closed receptacle is segmented into two functional receptacles: the first open receptacle for rapid insertion and the second closed receptacle for secure holding. This segmentation significantly reduces insertion time while maintaining secure holding throughout the coating process.
Solution Approach 2:
The dual receptacle system allows the round body to be quickly inserted into the first receptacle without requiring precise alignment or complex manipulation, reducing insertion time while the second receptacle automatically provides secure holding once the round body is transferred.

AI summary
The invention relates to an apparatus (10) for accommodating an article (14) in a vacuum-coating installation (5), having a carrier (12) with a coating opening (18), having a retaining device (20) for retaining the article (14) in the coating opening (18), and having a pivot bearing (32) for the retaining device (20), the pivot bearing being secured on the carrier (12), having a pivot axis (34), about which it is possible to pivot the retaining device (20) in order for the article (14) retained thereby to be turned in the coating opening (18), and having a bearing body (51, 5T) with a circumferentially closed mount (46) for a round body (36), which extends in the direction of the pivot axis (34), wherein the bearing body (51, 51') has a circumferentially closed mount (46) and a circumferentially open mount (48) for the round body (36), and therefore, when the retaining device (20) is being arranged on the carrier (12), the round body (36) can be introduced through the circumferentially open mount (48) into the circumferentially closed mount (46). The invention also relates to a method by means of which a retaining device (20) with an article (14) secured therein is arranged on the carrier (12) of the apparatus (10), to a handling apparatus for this purpose and also to a computer-program product.
