Abstract
The utility model discloses an adsorption apparatus constructs, this adsorption apparatus constructs including the sucking disc and be used for making the sucking disc communicate in tracheal connecting piece, in the sucking disc and/or be formed with the cavity in the connecting piece. When the vacuum pump suction is reduced or the vacuum pump stops operating, because the connecting piece and the sucking disc are internally provided with the cavities, the air pressure of the air between the plate and the adsorption mechanism cannot rise immediately, and the sucking disc cannot lose the adsorption capacity immediately along with the fluctuation of the vacuum pump.
Description
Technical Field
The utility model relates to an adsorption apparatus constructs.
Background
In the prior art, a plate member is generally conveyed by sucking the plate member with a suction cup.
Currently, there are two ways for adsorbing the plate: one is to use magnetic force for adsorption, which is limited in use and can only adsorb a plate such as a steel plate; the other is negative pressure adsorption, and a sucking disc made of silica gel and the like is used for sucking the plate in a vacuum pumping mode, and the sucking mode is not limited by the plate material.
At present, the structure of the sucker utilizing the vacuum suction mode has the following defects:
The bottom surface of the suction cup is almost a plane or has a great taper, when the air between the suction cup and the plate is pumped away, the bottom surface of the suction cup is almost completely contacted with the plate, so that almost no space exists between the suction cup and the plate, and when the air pump for vacuum pumping generates a pumping force drop or stops operating suddenly and unpredictably, the air can easily fill the space between the suction cup and the plate (so-called full filling means that the pressure of the air between the suction cup and the plate is the same as that of the outside air), so that the suction cup loses the suction force and the plate falls off.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned technical problem that exists among the prior art, the embodiment of the utility model provides an adsorption apparatus constructs.
For solving the technical problem, the embodiment of the utility model adopts the following technical scheme:
The suction mechanism comprises a suction cup and a connecting piece used for enabling the suction cup to be communicated with an air pipe, wherein a cavity is formed in the suction cup and/or the connecting piece.
Preferably, the upper portion of the suction cup is tapered such that a tapered first cavity is formed inside the suction cup, the connector includes a main body and a flared extension portion embedded in the upper portion of the suction cup, and the air tube is connected to the main body.
Preferably, a second cavity is formed in the main body, the first cavity is communicated with the second cavity, and the air pipe is communicated with the second cavity.
Preferably, the lower part of the sucker forms an extension part, and an annular bone plate is embedded in the extension part.
Preferably, the bone plate is made of a nylon material.
Preferably, the suction cup is made of a silicone material.
Compared with the prior art, the utility model discloses an adsorption apparatus constructs's beneficial effect is: when the vacuum pump suction is reduced or the vacuum pump stops operating, because the connecting piece and the sucking disc are internally provided with the cavities, the air pressure of the air between the plate and the adsorption mechanism cannot rise immediately, and the sucking disc cannot lose the adsorption capacity immediately along with the fluctuation of the vacuum pump.

Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, an embodiment of the present invention discloses an adsorption mechanism for adsorbing a plate. The suction mechanism includes a suction cup 10 and a connection member 20. The suction cup 10 is made of silicone and the upper part of the suction cup 10 is tapered so that a tapered first cavity 12 is formed in the suction cup 10. The connecting member 20 comprises a main body 21 and a flared extension 23 integrally formed on the lower portion of the main body 21, the extension 23 can be inserted into the upper portion of the suction cup 10 by injection molding, a second cavity 22 is formed in the main body 21, and the second cavity 22 is communicated with the first cavity 12. A connector tube 24 is provided at the upper end of the main body 21 to communicate with a gas pipe (the other end of the gas pipe is connected to a vacuum pump), and the connector 20 may be made of a nylon material.
When the plate conveying device is used, the vacuum pump is used for vacuumizing the first cavity 12 and the second cavity 22 through the air pipe, and under the action of negative pressure, the plate is adsorbed at the bottom of the sucking disc 10, so that the plate can be conveyed.
When the vacuum pump is reduced or the vacuum pump stops operating, the air pressure of the air between the plate and the adsorption mechanism is not immediately increased due to the cavities in the connecting member 20 and the suction cup 10, so that the suction cup 10 cannot immediately lose the adsorption capacity along with the fluctuation of the vacuum pump.
In a preferred embodiment of the invention, an annular bone plate 30 is embedded in the outer extension 11 of the lower part of the suction cup 10. The annular bone plate 30 serves to support the extension 11 so that the extension 11 does not collapse. In this embodiment, when the pumping force of the vacuum pump is too large, the extension portion 11 will not shrink and will not form a gap with the plate under the support of the annular bone plate 30, so as to prevent the external air from entering the suction cup 10 through the gap between the extension portion 11 and the plate, so as to maintain a certain negative pressure state in the cavity.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
