[0035] As described in the background art of the present application, after the blister box (product) is formed, the sheet is sent to the cutting station of the machine, and after being cut by the cutter, the blister box (product) and the sheet (corner material) remain two connection points, so that the blister box (product) will not fall off the sheet (corner material) after being cut; then the chain sends the sheet to the discharging station of the machine, the blister box is adsorbed by the vacuum chuck, the blister box (product) is pulled off from the sheet (corner material), and the blister box (product) is transferred to the conveying belt and transferred to the next process.

[0036] The present application is found that the surface of the existing part of the formed blister box can be used for adsorption area is very small, only small small vacuum chuck adsorption grabbing. Because the suction force of small vacuum chuck is small, its suction force is not enough to separate the cut blister box (product) from the corner material, so that the blister box (product) cannot be adsorbed and grabbed by the vacuum chuck, causing the production cannot be normal operation.

[0037] In order to solve the above problems, the present application provides the technical scheme of the present application, and the specific implementation is as follows:

[0038] Figure 1It is a schematic view of the grabbing device for the blister box in the embodiment of the utility model, Figure 2 It is a schematic view of the supporting mechanism in the embodiment of the utility model.

[0043] The bottom plate 31 is fixedly arranged on a forming machine table of the blister box and located at a discharging station of the machine table; the supporting plate 32 is located directly above the bottom plate 31 and below the vacuum suction cup 2; the four top corners of the supporting plate 32 are connected with the bottom plate 31 through the elastic supporting assembly 33, so that the supporting plate 32 can move up and down relative to the bottom plate 31; and the supporting plate 32 is used to support the blister box (product) 100.

[0044] In the embodiment, after the blister box formed by blister molding is cut by a cutter, the blister box is moved to the supporting plate (vacuum suction cup) at the discharging station of the machine table by a chain of the machine table; the blister box (product) is located above the supporting plate and below the vacuum suction cup.

[0045] The mechanical hand drives the suction cup base and the vacuum suction cup to move vertically downward; after the vacuum suction cup contacts the product (blister box), the product is adsorbed, and then the mechanical hand drives the suction cup base to continue to push the product downward; since the supporting plate is connected with the bottom plate through the elastic supporting assembly and the sheet material edge scraps after forming the product are pressed and fixed on the machine table, at this time, the elastic supporting assembly is compressed, the product and the supporting plate will continue to move downward relative to the edge scraps; after the product is moved downward by a certain distance, the product is disconnected from the edge scraps at the connecting point 110; and then the mechanical hand drives the suction cup base to move, so that the product (blister box) is adsorbed and grabbed and placed on the conveying belt of the discharging mechanism.

After the vacuum suction discs adsorb the product (blister box), the product is continuously pushed downward, so that the product and the supporting plate move downward. The elastic supporting assembly is compressed. When the product is pressed downward by a certain height relative to the edge scraps, the product is disconnected from the edge scraps at the connecting point. Then, the mechanical hand drives the suction disc base to move, so that the product (blister box) is grabbed and placed on a conveying belt, thereby ensuring the normal operation of production.
