AI Technical Summary

Technical Problem

During the lamination process of electrochromic film, the shaking of the positioning plate causes positional displacement, forming air bubbles, which affects the light transmittance and pass rate of the product. In addition, traditional tooling has poor versatility, increasing production costs and cycle time.

Method used

An electrochromic film lamination anti-bubble positioning fixture including a clamping device and a pressing device was designed. The clamping device enhances the stability of the positioning plate in the horizontal and vertical directions respectively through the clamping device and the pressing device, and gradually transmits pressure through the rotating contact material surface to prevent bubble formation.

Benefits of technology

It effectively prevents bubble formation, improves product light transmittance and pass rate, reduces edge bubbles, enhances tooling versatility, and reduces production costs and cycle time.

Abstract

This utility model relates to the field of electrochromic film processing technology, specifically to a lamination anti-bubble positioning fixture for electrochromic films. The utility model includes a positioning plate, with a film slidably connected to its inner surface. A clamping device is provided on the surface of the positioning plate, the clamping device including a fixing block slidably connected to the surface of the positioning plate. Two U-shaped frames are fixedly connected to the surface of the fixing block, and a round rod is fixedly connected to the inner surface of each U-shaped frame. An L-shaped pressure plate is rotatably connected to the arc surface of the round rod, and two torsion springs are sleeved on the arc surface of the round rod. The two ends of the torsion springs are respectively fixedly connected to one side of the L-shaped pressure plate and the inner surface of the U-shaped frame. A flat plate is fixedly connected to one side of the U-shaped frame. This invention solves the problem that during the lamination process, positional deviations caused by equipment movement, uneven pressure, or manual operation lead to material stacking deviations exceeding tolerance ranges, increasing interlayer gaps, forming bubbles, and affecting the product's light transmittance.
