Device for expanding display chip and checking surface flatness

Abstract

The invention relates to the technical field of display device manufacturing, and discloses a device for expanding a display chip and checking the surface flatness. The device comprises a chip processing device main body, a fixed disc is fixedly installed in the chip processing device main body, the left side of the fixed disc is provided with a through hole, and the left side of the fixed disc is provided with a through hole; and a conducting rod is slidably connected into the through hole, a rotor is movably installed in the fixing disc, sockets are fixedly installed on the inner walls of the left side and the right side of the chip processing device body, and an electric bell is fixedly installed at the top of the chip processing device body. The driving rod drives the rotor in the fixing disc to deflect, the rotor is an irregular disc, after the driving rod drives the rotor to deflect, the protruding area on the rotor moves to the conducting rod area to push the conducting rod into the socket, the electric bell is powered on, and the surface of the chip is informed of unevenness, so the effects of detecting the surface flatness of the expanded chip and reminding the operator are achieved.

Description

technical field [0001] The invention relates to the technical field of display device manufacturing, in particular to a device for expanding a display chip and checking the flatness of the surface. Background technique [0002] A display chip is a chip that provides display functions. Generally, they are composed of light-emitting diodes. There are generally two types of display chips: one is the display chip on the motherboard, also known as integrated graphics, and the other is the core chip of the independent graphics card, which provides a slot to connect to the motherboard. [0003] During the manufacturing process of the chip, it needs to be stretched, that is, to stretch the chip. However, most of the chips are stretched by hand today, resulting in uneven surface of the stretched chip, which reduces the quality of the chip. At the same time, the chip After the stretching process, the surface of the chip can be observed with the naked eye, and the quality of the chip...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for expanding the display chip and checking the surface smoothness, which can automatically expand the chip, ensure the quality of the expanded chip, reduce the burden of manual operation, and at the same time , the surface of the expanded chip is accurately detected, the chip with excellent expansion is selected, and the inferior chip is eliminated, which solves the problem that most of the expansion of the chip is manually stretched, resulting in uneven surface of the stretched chip , so that the quality of the chip is reduced. At the same time, the surface of the chip is observed with the naked eye after the chip stretching process, and the quality of the chip cannot be accurately distinguished.
