Hot pressing tool and hot pressing apparatus having the same
First Claim
1. A hot pressing tool including a moving block connected to a transfer instrument to be capable of moving up and down, the hot pressing tool comprising:
- a hot pressing head attaching an anisotropic conductive film (ACF) on a liquid crystal display (LCD) substrate;
a heater block having the same thermal expansion coefficient as the hot pressing head and including a plurality of heaters passing through the heater block in a width direction thereof; and
a connection unit connecting the heater block and the moving block,wherein the heater block is fixed to the connection unit,wherein a length direction of the connection unit extends in a direction parallel to a line connecting the hot pressing head, the heater block and the moving block,wherein the moving block and the heater block are spaced apart from each other and connected to each other by the connection unit, andwherein the connection unit is a plurality of adjustment bolts capable of adjusting the interval between the moving block and the heater block, thereby adjusting the oblateness of the hot pressing head, and the adjustment bolts are arranged in a line perpendicular to the length direction.

Abstract
The present invention relates to a hot pressing tool and a hot pressing apparatus having the same. According to the present invention, a hot pressing head attaching an anisotropic conductive film (ACF) on a liquid crystal display (LCD) substrate and a heater block supplying heat to the hot pressing head have the same thermal expansion coefficient, and the heater block is provided with a hot pressing tool connected to a moving block by connection units. Also, there is provided a hot pressing apparatus, including the hot pressing tool, which is provided with a support capable of attaching the LCD substrate on the ACF and a transfer instrument. Thus, according to the present invention, the operation can continue with almost no deterioration of the oblateness of the hot pressing head. Also, since the hot pressing apparatus has the structure of connecting the heater block and the hot pressing head together simply by the combination bolts with no need for adjustment bolts, it can be easily manufactured. Also, it is possible to prevent the decrease of work efficiency, and damage to the adjustment bolts caused by excessive use of the adjustment bolts.
