Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail by the accompanying drawings and specific embodiments.
A base plate of a vacuum chuck is characterized in that the bottom of the base plate is made of rubber, a communication hole communicated with the bottom of the base plate 18 is formed in the base plate 18 and penetrates through the upper end and the lower end of the base plate, a plurality of sealing lip edges 18-1 are arranged below the base plate 18, a plurality of radial connecting ribs 18-2 are arranged at the same time, the radial connecting ribs 18-2 are uniformly distributed in an annular mode, and the sealing lip edges 18-1 are divided into a plurality of small cavities in the circumferential direction by the radial connecting ribs 18-2. The radial connecting ribs 18-2 are slightly lower than the sealing lips 18-1, and three sealing lips 18-1 are arranged below the chassis 18. The radial ribs 18-2 serve to prevent complete lip leakage failure due to local breakage of the sealing lip 18-1.
The handle 15 is arranged at the upper end of the chassis 18, the communicating seat 16 communicated with the bottom of the chassis 18 is arranged at one end of the handle 15, a pipeline is arranged in the communicating seat 16, the pipeline is communicated with the bottom of the chassis 18 through a communicating hole in the chassis 18, the communicating seat 16 is connected to one end of the handle 15 through a screw, the handle 15 end of the communicating seat 16 and the mounting column of the chassis are of a hollow structure, the communicating seat 16 is accommodated in the hollow structure, the communicating hole in the chassis 18 is connected to one end of the pipeline on the communicating seat 16, and the other end of the pipeline is connected with an air vent in the handle 15.
The inside cylindric that is of handle 15, one end opening in the handle 15, the other end is sealed except setting up the air vent, and the air vent is hugged closely to the blind end inboard and is provided with rubber valve 14, and rubber valve 14 passes through jump ring 13 fixedly.
The rubber air gate 14 may allow air from the chassis 18 to enter the cavity in the handle 15 but not allow air from the cavity in the handle 15 to enter the chassis 18, i.e., unidirectional.
