Adsorption device and vacuum adsorption equipment capable of adsorbing soft object

Abstract

The invention discloses vacuum adsorption equipment capable of adsorbing a soft object. The vacuum adsorption equipment comprises a moving device, a plane adsorption plate and an adsorption device, wherein the moving device comprises at least one connecting arm and a driving device which is used for operating the connecting arm to move; the plane adsorption plate is connected to the connecting arm and comprises an adsorption surface which is used for allowing the soft object to lean and multiple vacuum air holes which are formed in the adsorption surface; the adsorption device comprises a suction disc body which is arranged on the plane adsorption plate, an adsorption bottom surface which is arranged at the bottom side of the suction disc body and a friction connecting piece which is arranged on the adsorption bottom surface. According to the vacuum adsorption equipment disclosed by the invention, the soft object leans against the friction connecting piece and is adhered to the adsorption surface of the circumferential side of the adsorption bottom surface when the soft object is adsorbed by the adsorption device.

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
