The present invention relates to a sealant dropping device, and more particularly, to a sealant dropping device that measures the weight of a sealant remaining in a clearance and minimizes inefficient material consumption caused by replacing the sealant after a predetermined time, To a dropping device.

In manufacturing a liquid crystal panel, a sealant is applied in a predetermined pattern or a coating operation for dropping liquid crystal is performed. Here, in the coating operation, a gas or the like having a predetermined pressure is supplied into the clearance so as to discharge a liquid such as a sealant or a liquid crystal from the nozzle while moving the nozzle relative to the substrate, while applying a discharge pressure to the liquid in the clearance , And a process of controlling the flow of the liquid supplied from the sheath to the nozzle.

When the liquid is discharged by such a coating operation, the amount of the liquid stored in the clearance gradually decreases. If the liquid in the clearance is completely consumed while performing the coating operation, the sealant may not be cut off or the liquid crystal may not be formed on the substrate, so that the liquid crystal panel may be defective. Therefore, after completion of the application operation, prior to the start of the subsequent application operation, for the purpose of replacement of the fresh food or setting of the gas supply amount supplied to apply pressure to the liquid within the food to the target pressure value, It is necessary to always check the remaining amount of liquid.

Therefore, in order to check the remaining amount of the liquid remaining in the clearance, there has been a method of confirming the remaining amount of the liquid in the clearance by forming the clearance in a transparent material and confirming the scale provided in the clearance.

However, even if the liquid is adhered to the wall surface of the sheath and the sheath is made of a transparent material, it is difficult to confirm the remaining amount of the liquid in the sheath.

In addition, in the conventional sealant dispensing apparatus, the time of replacement of the clearance is changed regardless of the remaining amount of the sealant, and the sealant is replaced irrespective of the remaining amount of the sealant inside the clearance, there was.

SUMMARY OF THE INVENTION The present invention has been made in an effort to solve the conventional problems as described above, and it is an object of the present invention to provide a sealant dispenser, which has a means for detecting the remaining amount of the sealant by comparing the weight before and after the sealant is used, And to provide a sealant dropping device for minimizing unnecessary consumption of a sealant generated in the sealant dropping device.

According to an embodiment of the present invention, there is provided a method of manufacturing a seal member, comprising: providing a sealant having a sheath portion accommodated therein, a nozzle portion provided at a lower portion of the sheath portion to discharge the sealant toward the substrate, And a sensing unit for sensing an amount of the sealant remaining in the sheath.

The apparatus may further include a header portion provided at a lower portion of the clearance portion for receiving and fixing the nozzle portion and the sensing portion.

The sensing unit may include a sensor unit for sensing the amount of the sealant remaining in the sheath and a notification unit for receiving a signal from the sensor unit to guide the replacement time of the sheath unit.

The sensor unit senses the remaining amount of the sealant remaining in the relief portion by comparing the weight of the relief portion when the sealant is fully charged with the weight of the relief portion after using the sealant.

In addition, the sensor unit sends a signal to the notification unit when the remaining amount of the sealant is less than a predetermined minimum amount of sealant, thereby guiding the replacement time of the clearance unit.

According to the sealant dropping apparatus of the present invention, the optimum clearance replacement time can be determined by sensing the weight of the sealant accommodated in the clearance and measuring the remaining amount of the sealant.

In addition, unnecessary consumption of the sealant caused by the method of replacing the clearance every predetermined period can be reduced, so that unnecessary consumption of the sealant can be minimized and the cost can be saved.

In addition, since it is possible to know when the shrug is to be replaced, the operation rate of the equipment can be increased by stopping the operation of the equipment only at the time of replacement of the shrug without the necessity of stopping the operation of the equipment.
