The invention discloses a device for controlling bad LCD powder agglomerate in the technical field of LCD production. The device comprises a box body, a front cover plate and a powder spray head. Thefront side of the box body is hinged to the left side of the front cover plate, a buckle lock is installed on the right side of the front side face of the front cover plate, an arc-shaped cavity is formed in the middle of the surface of the box body, and the front side and the rear side of the arc-shaped cavity respectively penetrate through the front side wall and the rear side wall of the box body. The device for controlling bad LCD powder agglomerate adopts the arc-shaped powder spray cavity, so that dust is not easy to accumulate, and meanwhile, the movement mechanism is arranged below, and the number of parts in the arc-shaped powder spray cavity is reduced, so that the adhesive positions of powder particles are reduced, and the installation positions of the powder spray head and thebox body are good in sealing performance; the bottom of the device is provided with a mineral oil layer which can be adhered with redundant powder particles; and the device is provided with a heatingdevice which can heat the powder particles, so that the phenomenon that the powder particles are agglomerated due to overhigh humidity is avoided, the formation of bad powder agglomerate is greatly reduced, and the product yield is improved.
Description
technical field [0001] The invention relates to the technical field of LCD production, in particular to a device for controlling defective LCD dough. Background technique [0002] The powder spraying process is to spray uniform powder particles on the PI surface of the LCD. The powder particles support the upper and lower substrates of the LCD and maintain the distance between the upper and lower glass substrates of the LCD to prevent changes in the liquid crystal response characteristics due to uneven thickness control. [0003] During powder spraying, the powder will float inside the powder sprayer for a long time and move relative to the airflow. The powder spraying head of the general powder spraying machine has the problem of poor sealing. When the parameters such as the air valve pressure of the powder spraying machine are normal, as the powder spraying time goes by, the floating powder will gradually spread on the inner wall of the powder spraying machine. The corner...
