Embodiment Construction

[0022] refer to Figure 4 Shown is a schematic plan view of the thermocompression bonding equipment of the present invention. The thermocompression bonding equipment 4 includes a thermocompression head device 41 , a positioning device 42 , a support table 43 and two imaging systems 44 .

[0023] The thermal head device 41 includes a first cylinder 411 , a second cylinder 412 and a pressure head 415 . A shaft coupling 413 connects the axis of the first cylinder 411 and the second cylinder 412 to form a double cylinder, and a holding block 414 is used to fix the pressure head 415 and cooperate with a chute (not shown) to Ensure that the pressure head 415 only moves up and down, and the holding block 414 is installed under the second cylinder 412 . Both the first cylinder 411 and the second cylinder 412 can move up and down independently to drive the pressure head 415 to move back and forth in one direction. The back and forth movement distance of the pressure head 415 is cont...

Abstract

The imaging system includes a light reflector, a half transmission and half reflector, a CCD camera device, and a light source. The said light reflector, the half transmission and half reflector and the CCD camera device are setup at an axis. Working face of the light reflector is parallel to working face of the half transmission and half reflector, and the angle between the said working face and the axis is 45 degree. Being perpendicular to the axis, the light source is setup opposite to the half transmission and half reflector. The imaging system is in use for realizing accurate alignment between electronic device such as IC for driving liquid crystal and faceplate of liquid crystal.

Description

【Technical field】 [0001] The invention relates to an imaging system in a thermocompression bonding device of a liquid crystal display. 【Background technique】 [0002] The liquid crystal panel includes two transparent substrates arranged oppositely, and liquid crystal sealed in the gap formed by the two transparent substrates. In order to display visible information such as characters and patterns on the liquid crystal panel, it is necessary to electrically connect a plurality of electrode leads formed on one of the transparent substrates to an electronic device IC for driving the liquid crystal. [0003] A prior art way of conductively connecting the IC and the electrode leads of the liquid crystal panel is as follows: figure 1 As shown, this connection structure 1 includes an IC 11 , a liquid crystal panel 12 and an ACF (Anisotropic Conductive Film, anisotropic conductive film) 13 . The forming process of the connection structure 1 includes: affixing a section of ACF 13 o...
