Problems solved by technology

Hyundai aims to make up for the light loss of the backlight panel. Most of them use a three-sided plastic frame structure. The light-incident side of the back panel adopts a closed structure. When the positioning jig is used to position the three-sided plastic frame, it will cause the plastic frame to be distorted. , has been unable to meet the needs of modern

Abstract

The invention relates to the field of optoelectronics, in particular to a three-side plastic frame size detecting device. The device comprises a machine table, a detecting substrate is mounted on a surface of the machine table, an external limiting mechanism and an inner limiting mechanism are respectively arranged on the detecting substrate, the outer limiting mechanism comprises a limited position splint, an upper plane of the detecting substrate is provided with a driving sleeve, a transmission threaded column penetrates through the driving sleeve, the driving sleeve is respectively locatedat the left and right ends of the transmission threaded column, the limited position splint is respectively mounted on the corresponding driving sleeve, the inner limiting mechanism includes a limited position frame, the rear side of the limited position frame is provided with a fixing sleeve, the fixing sleeve is installed in the detecting substrate through a movable shaft, threaded sleeves aremounted on the left and right sides of the limited position frame and a frame on the front side, and threaded rods penetrate through the threaded sleeves. The device maintains the complete limiting ofthe plastic frame, so that the plastic frame is supported as a whole, thereby facilitating the detection of the plastic frame.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a size detection device for a three-sided rubber frame. Background technique [0002] With the development of science and technology, the backlight of the mobile phone is getting thinner and thinner, and the supporting structure of the backlight is getting thinner and softer, and the assembly precision is getting higher and higher. Among them, the plastic frame needs to be installed during the backlight production process, that is, the plastic frame is placed on the light guide plate, and the inner wall of the plastic frame is attached to the outer wall of the light guide plate. The traditional assembly method in the industry is to rely on the operator to grab the reflective film, attach the reflective film to the plastic frame, and then manually install the light guide plate into the plastic frame. It is not difficult to see that this existing technology not only has low productio...
