AI Technical Summary

Technical Problem

Existing LCD backplate demolding fixtures are prone to causing backplate edge jamming, deformation or micro-cracks in thin-walled areas during the clamping process, or unstable clamping due to insufficient force, resulting in secondary damage during demolding and affecting molding quality and performance.

Method used

The intelligent clamping system, which employs electric push rod linkage control and pressure sensor monitoring, uses precise adjustment of the electric push rod and flexible clamping structure to monitor the clamping force in real time, avoiding deformation of the back plate caused by excessive force. Combined with rubber protective pads to buffer stress, it achieves symmetrical clamping and stable transfer.

Benefits of technology

It achieves precise control of clamping force during demolding, preventing backplate deformation. It is suitable for automated demolding of backplates of various materials and features a compact structure, intelligent control, and significant anti-deformation effect.

Abstract

This utility model belongs to the field of LCD backplate manufacturing technology, specifically a deformation-resistant LCD backplate demolding fixture, including a base plate, a slot frame above the base plate, a controller fixedly connected to the upper surface of the base plate, a sliding column slidably connected inside the slot frame, a first electric push rod fixedly connected to the inner bottom wall of the slot frame, the telescopic end of the first electric push rod fixedly connected to the bottom end of the sliding column, a support plate slidably connected to the inner wall of the sliding column, a second electric push rod above the support plate, the telescopic end of the second electric push rod fixedly connected to the upper surface of the support plate, and two third electric push rods below the support plate. Specifically, this utility model first drives the sliding column to rise and fall through the first electric push rod inside the slot frame, causing the support plate to move up and down, while the second electric push rod controls the precise vertical positioning of the support plate, forming a three-dimensional positioning system to adapt to the demolding requirements of molds of different heights.
