Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the vacuum adsorption device disclosed by the present invention comprises a tray body 1, wherein a plurality of suction nozzles 3 for vacuum adsorption are uniformly distributed on the bottom wall of the tray body 1, a chamber 2 communicated with all the suction nozzles 3 is arranged inside the tray body 1, a connection port 4 communicated with the chamber 2 is arranged on the top wall of the tray body 1, and the connection port 4 is used for connecting with an exhaust pipe for vacuum adsorption; in addition, the four corners of the bottom wall of the tray body 1 are provided with mounting columns 5, mounting holes 6 are formed in the mounting columns 5, and the tray body 1 is fixed on equipment needing to be mounted through the mounting columns 5.

As shown in fig. 1 and 2, the suction nozzles 3 are distributed on the tray body 1 along a line and are arranged at intervals in 6 rows, and the suction nozzles 3 in adjacent rows are arranged in a staggered manner, so that the positions covered by the suction nozzles 3 can be more comprehensive in a limited area, and more places on the surface of the plate of the adsorbed piece can be adsorbed and fixed by the suction nozzles 3, thereby achieving a better adsorption effect.

As shown in fig. 3, an air path 7 is arranged inside the suction nozzle 3, the bottom end of the air path 7 penetrates through the suction nozzle 3 to form an inlet 8, and a one-way valve is arranged inside each suction nozzle 3 and is triggered to open when the suction nozzle 3 presses the surface of the plate of the adsorbed piece; because not all panel are all solid in process of production, often can meet to have on some panel to perforate or wear the groove, for example, the FPC board, setting through the check valve, when this kind of panel is specifically adsorbed, the check valve with 3 departments of the suction nozzle that perforate or wear the groove to correspond can not triggered, be in the closed condition all the time, thereby this be in sucking disc 13 during operation can not communicate with outside air, ensure that vacuum adsorption device is in better vacuum nature and adsorption effect all the time, can be applicable to the production and processing of more different panels, the suitability is better.

As shown in the chamber 2 of fig. 3, the suction nozzle 3 includes an upper portion 31 and a lower portion 32 that are fixedly inserted into each other, a protrusion 9 inserted into the lower portion 32 is convexly disposed on the upper portion 31, the check valve includes an elastic member 11 and a trigger member 10 located at an inlet 8 of the air passage 7, the inlet 8 of the air passage 7 is disposed in a conical shape, the trigger member 10 is spherical and blocks the inlet 8 under the elastic force of the elastic member 11, the elastic member 11 is a spring, one end of the spring is fixed on the trigger member 10, and the other end of the spring is fixed with the protrusion 9; and wherein the diameter of the trigger 10 is greater than the width of the inlet 8 such that the trigger 10 is partially exposed from the inlet 8; therefore, when the vacuum suction device is used specifically, the suction nozzle 3 moves downwards to be in contact with the surface of a plate, the trigger piece 10 moves the compression spring inwards under the action of the plate to open the inlet 8, and the surface of the plate is well adsorbed under the vacuum suction action of the air passage 7; the whole structure is simple and the practicability is good.
