Problems solved by technology

[0013] Thus, the conventional sealant coating machine has a problem in that it is difficult to control the gap between the discharge hole 1a of the nozzle 1 and the substrate S to form a sealant pattern with a desired cross-sectional area.

Embodiment Construction

[0034] The sealant coating machine and the method for controlling the sealant coating machine according to preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Such as Figure 4 with Figure 5 As shown, the sealant coating machine according to the present invention includes: a frame 10, a worktable 20, a pallet 30, a pair of support moving guides 40, a head support 50, a head unit 60, and a control unit (not shown) . The table 20 is provided on the frame 10 so as to move in the X-axis direction or the Y-axis direction. The pallet 30 is installed on the workbench 20 , and the substrate S is placed on the pallet 30 . Support movement guides 40 are provided on opposite sides of the pallet 30 in such a manner as to extend in the Y-axis direction. The head support 50 is installed above the pallet 30 and extends in the X-axis direction in such a way that the opposite ends of the head support 50 are...

Abstract

The invention discloses a paste dispenser and a method for controlling the same. A nozzle can be moved vertically and independently from a laser distance sensor. When the interval between an outlet hole of the nozzle and a substrate can be adjusted to adjust the cross-sectional area of the paste pattern, the vertical position of the nozzle relative to the substrate can be adjusted, when the position of the laser distance sensor is fixed, thereby the laser distance sensor can be disposed at the best position relatively to the interval between the outlet hole of the nozzle and the substrate.

Description

technical field [0001] The present invention relates to a sealant applicator for applying sealant to a substrate and a method of controlling the sealant applicator. Background technique [0002] In general, flat panel displays (FPDs) are video displays that are thinner and lighter than conventional televisions and monitors that use 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 independently supplies data signals based on image information to liquid crystal cells arranged in a matrix, thereby controlling light transmittance of the liquid crystal cells, thereby displaying desired images. Since the LCD has the advantages of thinness, lightness, low power consumption, and low operating voltage, it has been widely used. A method of manufacturing a liquid crystal panel g...
