Problems solved by technology

However, in this case, the driving force of the moving portion 91 is too small to properly move the head unit 80, making it impossible to move the head unit 80 smoothly, causing several problems including vibration.
[0008] Thus, the problem with the conventional glue applicator is that reducing the interval between the sealant patterns P formed on the substrate S is limited due to the width Wm of the conventional moving part 91 in the X-axis direction.

Embodiment Construction

[0025] Hereinafter, a glue applicator and a method of controlling the glue applicator according to preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0026] Such as Figure 4 and Figure 5 As shown, the glue applicator according to the present invention includes a frame 10, a pallet 20, a pair of support movement guides 30, a head support 40, a head unit 50 and a control unit (not shown). The pallet 20 is installed on the frame 10 , and the substrate S is seated on the pallet 20 . Support movement 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 the pair of support movement guides 30 , and extends in the X-axis direction. The head unit 50 is mounted on the head support 40 to move in the X-axis direction. The control unit controls ...

Abstract

The present invention discloses a paste dispenser and a method for controlling the same. The paste dispenser is The paste dispenser is constructed to reduce the a distance between the nozzles when the head units are adjacent with one another. The paste dispenser can be effectively used for forming various patterns on a substrate.

Description

technical field [0001] The invention relates to a glue applicator for forming a sealant pattern on a substrate and a method for controlling the glue applicator. Background technique [0002] A glue applicator is a device that applies a sealant to a substrate in a predetermined pattern in order to bond or seal the substrate when various types of flat panel displays (FPDs) are manufactured. [0003] Such as Figure 1 to Figure 3 As shown, such a glue applicator includes a head unit 80 , a head support 89 and an X-axis drive unit 90 . Each head unit 80 is provided with a syringe 82 containing the sealant and a nozzle 83 discharging the sealant. The head support 89 movably supports the head unit 80 . Each X-axis driving unit 90 is inserted between the corresponding head unit 80 and the head support 89 to move the head unit 80 along the direction in which the head support 89 extends (X-axis direction). Each head unit 80 is provided with a laser displacement sensor 84 to measur...
