[0038] Referring to Figure 2 and Figure 3 , in this embodiment, the positioning assembly 3 comprises a positioning plate 31, the positioning plate 31 is fixedly connected with the movable plate 2, a notch 32 is formed in the positioning plate 31, a horizontal plate 33 is movably arranged in the notch 32, an active rod 34 is fixedly arranged on the top of the horizontal plate 33, the active rod 34 movably penetrates through the top of the positioning plate 31 away from the horizontal plate 33, a plurality of springs 35 are fixedly arranged between the horizontal plate 33 and the top of the notch 32, and a pressing rod 36 is fixedly arranged on the bottom of the horizontal plate 33.

[0039] Specifically, the plastic sheet and the wafer are placed on the movable plate 2, when the movable plate 2 drives the plastic sheet and the wafer to move towards the roller 5, the active rod 34 is pressed downward, the active rod 34 drives the horizontal plate 33 to move downward along the notch 32, so as to drive the pressing rod 36 to move downward, thereby pressing the two sides of the plastic sheet, and the plastic sheet can be fixed and limited, the springs 35 are stretched in this process, the state is maintained, so that the bottom of the roller 5 passes through, and the adhesive film is attached to the surface of the wafer, and the positioning plate 31 provides support for the springs 35.

[0040] Referring to Figure 2 and Figure 5 , in this embodiment, the housing 1 is fixedly provided with a limiting plate 6 on one side of the roller 5, the limiting plate 6 is axially symmetrically provided with a notch 61 on both sides, and the end of the active rod 34 away from the horizontal plate 33 movably abuts against the notch 61.

[0041] Specifically, when the movable plate 2 drives the plastic sheet and the wafer to move towards the roller 5, the top of the movable rod 34 will abut against the notch 61 on one side of the limiting plate 6 before reaching the roller 5, so that the movable rod 34 moves downward to drive the pressing rod 36 to abut against the plastic sheet for limiting, and then the movable rod 34 moves along the low part of the notch 61, in this process, the pressing rod 36 always limits the plastic sheet, and the state is maintained until the bottom of the roller 5 passes through, after the adhesive film is attached to the surface of the wafer, the movable rod 34 reaches the notch 61 on the other side of the limiting plate 6, moves from the high part to the low part of the notch 61, and under the action of the spring 35, drives the movable rod 34, the horizontal plate 33 and the pressing rod 36 to return to the initial position, so as to release the limiting and fixing of the plastic sheet, and facilitate the removal of the plastic sheet and the wafer.

[0042] Referring to Figure 5 In the embodiment, a vertical groove 62 is formed in one of the limiting plates 6, the vertical groove 62 penetrates through the limiting plate 6 and one side of the shell 1, a lifting plate 7 is movably arranged in the vertical groove 62, one end of the lifting plate 7 is fixedly provided with a scraper 8, and the scraper 8 movably abuts against the object to be attached with the film.

[0043] Specifically, when the pressing rod 36 keeps abutting against the plastic sheet and passes through the bottom of the roller 5, a part of the adhesive film covers one side of the plastic sheet and the wafer, and continues to move in the same direction, the plastic sheet covered with the adhesive film will first abut against the scraper 8, the bottom of the scraper 8 can be made of flexible material to avoid damaging the plastic sheet or the wafer, and the movement of the scraper 8 along the surface of the plastic sheet will make the adhesive film more closely attached to the plastic sheet, when the scraper 8 is about to abut against the wafer, since the wafer has a certain thickness, if the height of the scraper 8 is not adjusted, the abutment between the scraper 8 and the wafer during the movement of the wafer will cause damage to the wafer, therefore, the lifting plate 7 can be moved upward along the vertical groove 62, the upward movement of the lifting plate 7 will drive the scraper 8 to move upward, so that the bottom of the scraper 8 is attached to the top of the wafer, so as to make the adhesive film more closely attached to the wafer, when the scraper 8 no longer abuts against the wafer, the lifting plate 7 can be moved downward to the initial position, so that the scraper 8 can make the adhesive film on the other side of the wafer more closely attached to the plastic sheet.

[0045] Specifically, the movable plate 2 drives the plastic sheet and the wafer to move, and also drives the fixed plate 9 to move. When the movable plate 2 passes below the roller 5, the adhesive film is attached to the surface of the wafer. Then, the fixed plate 9 moves along the moving groove 102, so that the limiting rod 10 contacts with the limiting groove 91. The limiting rod 10 moves horizontally along the low part of the inclined groove on one side. In this process, the height of the limiting rod 10 does not change, and the height of the lifting plate 7 and the scraper 8 does not change. The adhesive film on one side of the wafer is attached to the plastic sheet more tightly. With the movement of the fixed plate 9, the limiting rod 10 moves upward along the inclined groove on one side, so that the lifting plate 7 and the scraper 8 move upward. In this way, the wafer and the adhesive film can be attached tightly. The limiting rod 10 moves along the high part of the inclined groove for a distance, reaches the inclined groove on the other side, and moves downward along the inclined groove, so that the lifting plate 7 and the scraper 8 return to the initial height. The adhesive film on the other side of the wafer is attached to the plastic sheet more tightly.

[0046] Referring to Figure 5 In the embodiment, the position of the scraper 8 is located between the two gaps 61.
