Problems solved by technology

[0004] The adsorption device using the adsorption means with the above-mentioned structure uses a plurality of air solenoid valves to control the vacuum state, so not only the procurement cost of parts is high, but also the cost of manufacturing is naturally increased due to the large number of manufacturing processes.
[0005] Moreover, the conventional adsorption device is a custom-made type manufactured according to the specifications of the target object, so when the specification of the target object becomes larger or smaller or the shape of the target object changes, the adsorption device must be remanufactured, in order not to remanufacture the adsorption device , it is necessary to install another program on the device to adjust the number or shape of the operating adsorption means, but because it requires additional components as described above, the price of the device also increases, and whenever the object to be adsorbed changes At the same time, the operating status of the adsorption means must be set one by one, so it is also inconvenient in operation

Abstract

The present invention relates to a vacuum adsorption system capable of vacuum-adsorbing flat panel type objects such as steel plates, glass, or semiconductor wafers, and various articles having a planar surface, which includes: a suction-compression means for air suction and compression; an adsorption means operating under an active control of a vacuum regulation member according to the existence of a target, the absorption means carrying out the vacuum-adsorption operation if a target exists while stopping the air suction process in the absence of a target; a connection pipe for connecting the suction-compression means and the adsorption means; and a control (or sluice) valve installed in the connection pipe for controlling the air flow. The vacuum state of the adsorption means can be actively controlled according to the size or shape of a target (ultimately according to the existence of a target).

Description

technical field [0001] The present invention relates to a vacuum adsorption system, and more specifically, to a vacuum adsorption system capable of vacuum-absorbing flat-plate-shaped objects such as iron plates, glass, or wafers for semiconductor materials, and various items with smooth surfaces. . Background technique [0002] Vacuum absorbs a flat plate-shaped target object or a cube-shaped target object with a smooth plane, and lifts the object or moves it to a desired position while being sucked. Several types of suction devices have been developed and used. However, most of these adsorption devices are made by setting a plurality of adsorption means (mats, adsorption holes, etc.) on a block manufactured according to the specifications of the object to be adsorbed. [0003] Like the above-mentioned conventional suction means, air is sucked and compressed by air solenoid valve and other means, and the target object is vacuumed and sucked by the compressed air. Wherein, ...
