Problems solved by technology
[0002] Due to the large size and thin thickness of the current liquid crystal glass substrate, generally only 0.3mm, and the operating load can reach 1 ton, it is very easy to break the glass due to vibration during transportation.
During the transportation of liquid crystal glass substrates, it is often encountered that the servo motor vibrates due to high-speed operation, which will reduce industrial production efficiency and seriously cause safety hazards, so it is necessary to take appropriate measures to avoid this situation.
At present, the source of vibration is mainly when the servo motor is running normally, and the traditional acceleration and deceleration methods are easy to cause vibration

Embodiment Construction
[0013] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.
[0014] Such as figure 1 As shown, the liquid crystal glass substrate is placed in the cassette 5, and the belt is driven by the servo motor 4 to load and transport the liquid crystal glass substrate. The liquid crystal glass substrate is transported between the upper limit sensor 1 and the lower limit sensor 3 through the belt. Before transportation, return to the origin sensor 2 for positioning, and then move. If the cassette 5 touches any limit sensor in the upper limit sensor 1 or the lower limit sensor 3, the servo motor 4 will stop moving. Wherein the servo motor 4 adopts a Mitsubishi servo motor whose model is HG-SR102B.
[0015] During the transportation of the liquid crystal glass substrate, the acceleration of the servo motor in the equipment for transporting the liquid crystal glass substrat...

The invention discloses a liquid crystal glass substrate transport vibration damping and suppressing control method. Through adjustment of the acceleration of a servo motor in a liquid crystal glass substrate device based on a transport distance and an object transport speed, the acceleration of the servo motor changes in sine wave shape. Because the change curve of the motion acceleration of the servo motor has a sine wave shape, the stability of the motor motion is effectively raised, and vibration damping effect is realized; in addition, through setting of an adaptability tune mode, a mechanical resonance inhibition filter and a trap wave wave-shaped selection, the resonance is eliminated. The problem of vibration in the transport process of the liquid crystal glass substrate is solved; the production efficiency is raised; and the product fraction defective is reduced. The operation is more simple and convenient; the liquid crystal glass substrate transport is more rapid and safer.
