LCD TFT or ODF glass cutting produces flange solution

Causes and Solutions of Flange

1. The stroke of the cutter wheel is exceeded, and the cutter shaft of the cutter wheel is severely worn. This situation has been completely eliminated.

Through the upper and lower line control of the cutter wheel, the electronic file and paper file record the time, machine number, stroke, replacement person, etc.

data. During the cutting wheel stroke, the cutting section can be clearly visible.

2.The glue-like object is attached to the back of the SUB to be cut (source: gloves, transit TRAY tray) or platform

The glass debris on the platform and the platform have bumps.

The glass at the location of the foreign object is cushioned, the height is the highest point of the whole SUB, and a circle is formed around it.

The location of the object is the center of the circle, and the arch height from the center of the circle to the surroundings gradually decreases.

Condition 1 The cutter wheel walking on the edge of the padding area (that is, the circumference of the circle) will cause a smaller flange from the edge.

To the center of the circle

Condition 2. Colloid or glass debris is on the cutting line or the edge of the cutting line-____-can cause cracks or large

Of the flange.

Condition 3. The platform has small bumps. This condition will cause a fixed position, continuity, and the same scrap.

In response to this situation, we adopt the following methods:

1) When the flange condition occurs, the cutting station biotechnology first checks and repairs the operating platform to prevent it from appearing.

Continuous scrapping, after confirming that there is no problem with the platform, then analyze according to other thinking.

2) The latest written work instructions are in the process of implementation. Biotech personnel make irregular inspections to

And guide the blow platform action and time.

3) Require the production line supervisor to strictly require the operator to perform the operation in full accordance with the operation instructions and

carefully.
