Glass Substrate Loading Bracket Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency and high cost of solar power generation are partly due to the brittle nature of glass substrates, which require deep robotic arm extension into brackets for loading, reducing substrate capacity, increasing fabrication time, and production costs.
Innovation Solution
An ancillary apparatus comprising a holding rack, guiding mechanism, and glass lifting mechanism allows robotic arms to load glass substrates into brackets without entering the bracket, utilizing the space for more substrates, including guiding rollers and a brace rack for precise positioning and lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robotic arm is extended deeply into the bracket to load glass substrates, then the glass substrate can be securely loaded without dropping, but the bracket capacity decreases and fabrication time increases
Solution Approach 1:
A robotic gripper is introduced as an intermediary tool between the robotic arm and the glass substrate. The gripper can be extended into the bracket to secure the substrate, while the robotic arm itself remains outside the bracket. This allows secure substrate handling without requiring the arm to occupy bracket space, resolving the contradiction between loading security and bracket capacity.
Solution Approach 2:
The loading system is segmented into separate functional components: the robotic arm for positioning, the extendable gripper for secure holding, and the bracket for storage. This segmentation allows each component to perform its specific function optimally - the gripper can extend into the bracket only when needed for loading, while the bracket maintains its full capacity for storing multiple substrates.
2Reliability
If the robotic arm is extended into the bracket, then the glass substrate can be held securely, but the space in the bracket is reduced
Solution Approach 1:
The extendable gripper acts as an intermediary that can penetrate into the bracket space only during the loading operation. Once the substrate is secured and loaded, the gripper retracts, freeing up the bracket space. This allows secure substrate handling without permanently reducing the bracket's storage capacity.
3Reliability
If the robotic arm is extended into the bracket, then the glass substrate can be loaded safely, but the fabrication time increases
Solution Approach 1:
The gripper is designed with dynamic extendability, allowing it to extend into the bracket only when needed for substrate loading and retract when not needed. This dynamic adjustment optimizes the loading process by providing secure substrate handling during critical moments while minimizing interference with other operations, thereby reducing overall fabrication time.

AI summary
An ancillary apparatus for loading glass substrates into a bracket through a robotic arm includes a holding rack to hold a bracket, a guiding mechanism located above the bracket and a glass lifting mechanism located below the bracket. The robotic arm grips the glass substrate and moves the glass substrate above the bracket to be guided by the guiding mechanism and held by the glass lifting mechanism, and then the glass substrate is released from the robotic arm. The glass substrate is guided by the guiding mechanism and braced by the glass lifting mechanism, and then is lowered slowly into the bracket. Hence the robotic arm does not need to be entered the bracket to load the glass substrate, extra space to receive the robotic arm can be saved and thus more glass substrates can be loaded. The cost is reduced and productivity is improved to meet production requirements.
