SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a vacuum chuck structure to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that how to improve the reliability of adsorbing panel.
The purpose of the utility model can be realized by the following technical proposal: a vacuum sucker structure is characterized by comprising a mounting frame, a sliding rod, a corrugated pipe and a tension spring, wherein a joint and a sliding sleeve sleeved on the sliding rod are arranged on the mounting frame, the corrugated pipe is connected to the lower end of the sliding rod, the tension spring is connected to the sliding rod between the corrugated pipe and the sliding sleeve, a first air hole is formed in the joint, a second air hole and an air groove penetrating through the top of the sliding rod are formed in the sliding rod, the first air hole can be communicated with the second air hole through the air groove, the second air hole is communicated with the air groove and the corrugated pipe, and an opening in the upper end of the second air hole is staggered with the first air hole; when the sliding rod is abutted against the top of the sliding sleeve, the through-flow section formed between the air groove and the top of the sliding sleeve is smaller than that of the air hole II, and the through-flow section formed between the air groove and the top of the sliding sleeve is smaller than that of the air hole I.
The corrugated pipe is used for being in contact with a plate, before the plate is contacted with the plate or after the plate is contacted with the plate, the plate is contacted with the top wall of the sheath under the action of a tension spring, the joint is connected with a negative pressure air source, the air flow of the negative pressure air source acted on the corrugated pipe is smaller because of the limitation of an air groove with a smaller circulation surface, the negative pressure borne by the plate is also smaller, after the plate is suspended, the tension spring is stretched under the action of the gravity of the plate, the top of the sliding rod is separated from the top wall of the sliding sleeve, the circulation section between the air hole I and the air hole II is enlarged, the negative pressure borne by the corrugated pipe is increased, the dead weight of.
If the negative pressure is not enough to drive the plate to be suspended, the negative pressure of the air source is adjusted to be larger, otherwise, the plate is in risk of falling after being suspended.
The upper end of the air hole II is bent to the eccentric position of the sliding rod, so that the air hole I in the central position of the sliding sleeve is staggered with the air hole I.
In the above vacuum chuck structure, the mounting frame has a horizontal adjusting groove.
The adjusting groove is used for adjusting the position of the corrugated pipe so as to be suitable for the adsorption of plates with different sizes.
