Buffer Cylinder

The present invention relates to a buffer cylinder, and more particularly, through two processes of buffer and alignment to prevent glass burnout caused by collision with the LCD alignment mechanism when the LCD glass to be transported along the conveyor belt is aligned. It relates to a buffer cylinder to be driven.

In general, automation facilities are essential for mass production of display devices.

The LCD glass, which is the main core of the display device, requires an alignment process during movement, and requires a plurality of LCD alignment mechanisms to align the LCD glass.

The LCD alignment mechanism is usually coupled to the upper portion of the floating plate, the floating plate is coupled to the piston rod of the cylinder structure to align the LCD glass.

Therefore, the LCD alignment mechanism is in close contact with the LCD glass according to the reciprocating motion of the piston rod of the cylinder.

However, the conventional LCD alignment mechanism has a problem that a large impact is generated by the moving force of the piston rod when in close contact with the first LCD glass.

Therefore, the LCD alignment mechanism has always been a problem that the LCD glass is damaged or damaged by the collision with the LCD glass.

Therefore, there is a demand for a device having a structure capable of preventing damage to the LCD glass due to the collision between the LCD alignment mechanism and the LCD glass.
