Adsorption device and vacuum adsorption equipment capable of absorbing soft objects

Abstract

A vacuum adsorption device capable of absorbing soft objects, comprising a moving device, a plane suction plate and an adsorption device, the moving device includes at least one connecting arm, and a driving device for operating the connecting arm to move. The planar suction plate is connected to the connecting arm, and includes a suction surface for the soft object to rest on, and a plurality of vacuum holes arranged on the suction surface. The adsorption device includes a suction cup body installed on the plane suction plate, an adsorption bottom surface arranged on the bottom side of the suction cup body, and a friction piece arranged on the adsorption bottom surface. When the soft object is adsorbed by the adsorption device, it relies on the friction plate and is attached to the adsorption surface on the peripheral side of the adsorption bottom surface.

Description

technical field [0001] The invention relates to a vacuum adsorption device, in particular to a vacuum adsorption device which can be used to adsorb soft objects. Background technique [0002] There are two main types of vacuum chuck technologies, one is a contact vacuum chuck, and the other is a non-contact vacuum chuck. [0003] Generally speaking, the more common and widely used technology is the contact vacuum chuck technology. Its principle is to directly apply the negative pressure generated by the flow of gas from the inlet to the outlet to the object to be adsorbed. To achieve the purpose of absorbing objects. Since the negative pressure is directly applied to the object, when the object is adsorbed on the suction cup, a vacuum-like environment can be formed in the air chamber, so that the object can be tightly combined with the suction cup. Therefore, the contact suction cup can carry relatively heavy loads. However, when the contact vacuum chuck absorbs the object...

In addition, Patent No. 201240009 in Taiwan, China discloses a non-contact vacuum suction cup. The suction cup is provided with at least one anti-collision pad on the adsorption surface. However, the above-mentioned non-contact vacuum suction cup must still use a frame to limit its position. To achieve the purpose of transferring the blank, and in use, the blank may still collide with the suction cup or the anti-collision pad on the suction cup due to the vibration generated during transfer and turning over, resulting in repeated collisions on the surface of the blank. Strike pads thus causing damage to the blank surface

Furthermore, when all the above-mentioned vacuum adsorption devices absorb the soft board, the soft board may sag due to uneven force, so that the soft board will warp and wrinkle when it is transferred, and these warping and wrinkles will cause It may cause inconvenience in detection, or even cause damage to the soft board during transfer
