[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] A wafer fetching device of a wafer laminating machine comprises a body 8 of the laminating machine, a laminating platform 15 and a laminating device 9, wherein the laminating platform 15 is arranged on the body 8, the laminating device 9 is arranged on the body 8, a circular groove 6 is opened on the laminating platform 15, and a placing table is arranged in the circular groove 6.

[0024] The placement table includes a main body 3, a cylinder 13 and a fixed plate 2. The main body 3 is fixedly arranged in the circular groove 6. A mounting groove 12 is opened on the side of the main body 3 away from the body 8. The cylinder 13 is fixedly arranged in the mounting groove 12. The fixed plate 2 is fixedly arranged on the telescopic axis of the cylinder 13. The fixed plate 2 is located in the mounting groove 12. When the cylinder 13 is not working, the height of the fixed plate 2 is consistent with that of the main body 3.

[0025] The wafer to be filmed is placed on the main body 3, and the film-sticking device 9 sticks the film on the wafer. After the film is stuck on the wafer, the cylinder 13 is started, and the fixed plate 2 is lifted up by the cylinder 13. The wafer with the film stuck is moved away from the main body 3 as the fixed plate 2 is lifted up. At this time, it is convenient to remove the wafer from the main body 3.

[0026] The diameter of the placement table is smaller than the diameter of the circular groove 6. An electric telescopic rod 14 is fixedly installed in the circular groove 6. The electric telescopic rod 14 is between the film-sticking platform 15 and the placement table. There are multiple electric telescopic rods 14 in the circular groove 6. The electric telescopic rod 14 is fixedly connected to a positioning ring 4. The placement table is located in the positioning ring 4.

[0027] An infrared sensor 7 is fixedly arranged on the machine body 8, and the infrared sensor 7 is electrically connected to the electric telescopic rod 14. When the wafer to be laminated needs to be placed on the placement table, the staff touches the infrared sensor 7, the electric telescopic rod 14 is started, and the positioning ring 4 is lifted up by the electric telescopic rod 14. At this time, the top of the positioning ring 4 is higher than the top of the placement table, which makes it convenient to quickly and correctly place the wafer on the placement table without constantly adjusting the placement position of the wafer.

[0028] When the wafer is placed and touches the infrared sensor 7 again, the electric telescopic rod 14 contracts, and the positioning ring 4 moves closer to the bottom of the circular groove 6. At this time, the bottom of the positioning ring 4 is lower than the top of the placement table.

[0029] The positioning ring 4 is provided with a fixing opening 5, which is convenient for the staff to place the wafer on the placement table. A protective cover 1 is rotatably provided on the machine body 8, a rotating rod is rotatably provided on the protective cover 1, a cutter 10 is fixedly provided on the rotating rod, two cutters 10 are provided on the rotating rod, and the two cutters 10 are respectively provided at both ends of the rotating rod, and a tight layer 11 is fixedly provided on the rotating rod, and the tight layer 11 is between the two cutters 10.

[0030] When the wafer film is pasted, the protective cover 1 is closed on the machine body 8, the cutter 10 is pressed against the positioning ring 4, the pressing layer 11 is pressed against the wafer, the rotating rod is rotated, and the cutter 10 cuts off the excess film; the pressing layer 11 makes the film and the wafer fit better during the rotation of the rotating rod.

[0031] The implementation principle of this embodiment is: after the wafer is pasted with film on the film laminating machine, the protective cover 1 is opened, the cylinder 13 is started, and the fixed plate 2 is lifted up by the telescopic shaft of the cylinder 13. The wafer pasted with film is lifted up by the fixed plate 2 and moves away from the main body 3. At this time, there is a certain gap between the main body 3 and the wafer, which is convenient for the staff to remove the wafer from the main body 3 through the gap, thereby achieving the effect of facilitating the removal of the wafer pasted with film from the wafer laminating machine.
