Embodiment Construction

[0028] Hereinafter, an apparatus for detecting a remaining liquid amount according to an embodiment of the present invention is described with reference to the accompanying drawings.

[0029] Such as figure 1 with 2 As shown, the sealant coating machine having the remaining amount detection apparatus according to the present invention includes a frame 10, a pallet 20, a pair of support moving guides 30, a head support 40, a plurality of head units 50, and a control unit ( not shown). The pallet 20 is installed on the frame 10 , and the substrate S is located on the pallet 20 . The support moving guides 30 are installed on both sides of the pallet 20 in such a manner as to extend in the Y-axis direction. The head support 40 is installed above the pallet 20 in such a manner that both ends of the head support 40 are supported by a pair of support moving guides 30 and extend in the X-axis direction. A plurality of head units 50 are mounted to the head support 40 in such a mann...

Abstract

The invention discloses an apparatus for detecting residual liquid quantity, comprising a first path for transmitting a pressure for discharging liquid to an injector and a second path for transmitting a pressure for detecting residual liquid quantity to the injector. With the apparatus, the time from supplying pressure through the first path to discharging the liquid is minimal, and the residual liquid quantity in the injector can be measured more precisely through the second path.

Description

technical field [0001] The present invention relates to an apparatus for detecting the amount of liquid remaining in a syringe provided in a liquid supply device such as a sealant applicator. Background technique [0002] In general, a flat panel display (FPD) is a video display that is thinner and lighter than a conventional television or monitor that uses cathode ray tubes. Examples of FPDs that have been developed and used are liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and organic light emitting diodes (OLEDs). [0003] Among them, the LCD is a display that individually supplies a data signal based on image information to liquid crystal cells arranged in a matrix, thereby controlling light transmissibility of the liquid crystal cells, thereby displaying a desired image. Since LCDs are advantageous in that they are thin, light, and have low power consumption and operating voltage, they are widely used. A method of manufa...
