Adsorption device

Abstract

The invention provides an adsorbing device. The adsorbing device comprises a tube body, an adsorbing disc, a piston, a sealing part, a pressing part, an elastic part and a positioning assembly, wherein an accommodating cavity is arranged inside the tube body; the adsorbing disc is arranged on the end part of the tube body and communicates with the accommodating cavity; the piston is arranged in the accommodating cavity and sequentially moves back and forth among an upper limit position, a middle position and a lower limit position along the tube body; the sealing part is arranged between the piston and the tube body; the pressing part is arranged at one end of the tube body in a penetrating mode, and is used for pushing the piston to move towards the lower limit position under action of pressure; the elastic part is arranged in the accommodating cavity and is used for continuously applying force towards the pressing part to the piston; and the positioning assembly is matched with the elastic part after the piston moves to the lower limit position, and is used for positioning the piston to the middle position or the upper limit position. The adsorbing device disclosed by the invention can be used for improving adsorbing stability and the fool-proof effect.

Description

technical field [0001] The present disclosure relates to the technical field of liquid crystal panels, in particular, to an adsorption device. Background technique [0002] In the manufacturing process of LCD panels, it is often necessary to transfer fragile products such as panels or glass substrates. In order to avoid damage, a special adsorption device is generally used to absorb the product, and then transferred to the predetermined location. There are many types of existing suction devices, and devices such as a hand-held suction ball or a vacuum suction pen can be used for components such as panels or substrates with small sizes. The suction ball is usually a hollow spherical structure of rubber material, which can generate a certain vacuum by manual extrusion, and play an adsorption role on the product; the vacuum suction pen needs to be connected with a special vacuum device, through the suction effect of the vacuum device Adsorb the product. [0003] Due to the s...

AI Technical Summary

Problems solved by technology

[0003] Due to the soft texture of the existing suction ball, the stability of adsorption is poor, and the adsorption force is easily reduced or disappeared due to accidental touch, causing the product to fall and be damaged; while the existing vacuum suction pen requires a special suction device and has a complex structure. , the cost is high, and the operation is inconvenient, and the fool-proof effect of the above two needs to be improved
