Screen Mask Cleaning Device Brake Mechanism Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cleaning device for screen masks in screen printers requires complex control mechanisms to manage the lifting/lowering of the cleaning head and the brake mechanism, leading to unnecessary complexity in preventing slack of the cleaning sheet during reciprocating motion.
Innovation Solution
A cleaning device with a lifting and lowering mechanism interlocked with a brake mechanism that restricts the rotation of the supply section when the cleaning head is lifted, eliminating the need for separate control of these mechanisms by using a single air passage system to simplify the configuration and reduce components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the brake mechanism is operated separately from the lifting and lowering mechanism to restrict rotation of the supply section, then the cleaning sheet slack is suppressed, but the control mechanism becomes complicated
Solution Approach 1:
The brake mechanism is integrated with the lifting and lowering mechanism by sharing the same air passage system. The air cylinder that drives the lifting and lowering motion also drives the brake mechanism through a connected air passage, allowing both functions to be controlled by a single control signal and eliminating the need for separate control systems.
Solution Approach 2:
The air cylinder serves multiple functions: it provides lifting force to raise and lower the cleaning head, and simultaneously provides braking force to restrict rotation of the supply section. This multi-functionality is achieved by connecting both mechanisms to the same air supply system, allowing one component to perform multiple roles.
2Ease of manufacture
If separate control systems are used for the lifting/lowering mechanism and brake mechanism, then each mechanism can be optimized independently, but the number of components and control complexity increases
Solution Approach 1:
The lifting and lowering mechanism and brake mechanism are merged into a single integrated system. Both mechanisms share the same air cylinder and air passage infrastructure, reducing the total number of components while maintaining the ability to independently optimize each function's performance characteristics.
