Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laminating machines for liquid crystal panels experience an overpressure phenomenon due to the structure of the plate fixing member, leading to light spot defects in glass plates, resulting in reduced product yield and increased manufacturing costs.
Innovation Solution
A device for mounting a plate fixing member in a laminating machine, where the plate fixing member is arranged in a mounting slot and can move vertically, controlled by an elastic reset member, such as a compression spring, to prevent overpressure by compressing and moving into the slot during the pressing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plate fixing member is mounted with its bottom surface extending out of the mounting slot to facilitate glass plate engagement, then the ease of operation is improved, but the glass plates suffer overpressure phenomenon leading to light spot defects
Solution Approach 1:
The plate fixing member is designed to be movable within the mounting slot rather than fixed. It can move vertically between protruding from the slot (for engagement) and retracting into the slot (to avoid overpressure). This dynamic positioning resolves the contradiction by allowing the member to adapt its position based on operational requirements.
Solution Approach 2:
An elastic component serves as an intermediary between the plate fixing member and the mounting slot. This elastic component enables the plate fixing member to move smoothly and provides cushioning during the pressing operation, preventing direct hard contact that would cause overpressure while maintaining the engagement function.
2Reliability
If the plate fixing member is fixed in the mounting slot to maintain stable position, then the reliability is improved, but the overpressure phenomenon occurs during pressing operation
Solution Approach 1:
The plate fixing member transitions from a static fixed position to a dynamic movable position within the mounting slot. The elastic component provides restoring force to maintain reliability while allowing controlled movement to prevent overpressure during pressing operations.
Solution Approach 2:
The elastic component is installed in advance between the plate fixing member and the mounting slot to provide cushioning effect. This beforehand cushioning prevents overpressure from occurring during the pressing operation by absorbing excess force through elastic deformation.
3Manufacturing precision
If the plate fixing member protrudes from the mounting slot to ensure proper contact with glass plate, then the manufacturing precision is improved, but the overpressure phenomenon reduces product yield
Solution Approach 1:
The plate fixing member can dynamically adjust its position: protruding from the mounting slot during engagement to ensure manufacturing precision, and retracting into the mounting slot during pressing to prevent overpressure that would reduce product yield. This dynamic behavior resolves the contradiction between precision and productivity.
Solution Approach 2:
The plate fixing member performs periodic movement between protruding and retracting positions within the mounting slot. During engagement phase it protrudes for precision contact, during pressing phase it retracts to avoid overpressure. This periodic action maintains both manufacturing precision and product yield.

AI summary
The present disclosure relates to a device for mounting a plate fixing member in a laminating machine, including a mounting slot for mounting the plate fixing member. The plate fixing member is arranged in the mounting slot and can move vertically in the mounting slot. An elastic reset member is arranged between the plate fixing member and the mounting slot. With the movable plate fixing member being arranged in the mounting slot and the movement of the plate fixing member in the mounting slot being controlled by the elastic reset member, the plate fixing member can move into the mounting slot without an overpressure phenomenon of the glass plates at the plate fixing member when the top plate moves downwards and press-fits the upper glass plate and the lower glass plate. Therefore, the yield of products can be improved, and the production cost can be reduced. The present disclosure further relates to a top plate for a laminating machine and a laminating machine, with which the overpressure phenomenon of the glass plates caused by the plate fixing member can be effectively reduced.
