Mounting frames 5 are fixed on both sides of the movable base 4, and a film laminating roller assembly 51 and a film carrier 52 are fixed on the top of the mounting frame 5. The film laminating roller assembly 51 is located between the film carrier 52 and the movable base 4. Please refer to Figure 2 As shown, a plurality of air extraction channels 522 are provided on the diaphragm carrier 52, and the air extraction channels 522 are connected to an external air extraction pump through an air pipe (not shown in the attached figure). The diaphragm 8 is placed on the diaphragm carrier 52, and the diaphragm carrier 52 adsorbs the diaphragm 8 through the air extraction channels 522 and the external air extraction pump to ensure that the position of the diaphragm 8 will not change before the film is applied. At the same time, the two diaphragm carriers 52 adsorb the two ends of the diaphragm 8 to fully ensure the stability of the module; the middle part of the diaphragm 8 is covered on the movable base 4, and the subsequent products are placed on the movable base 4 and pressed on the top of the diaphragm 8. The pressing mechanism 2 drives the pressing block 24 downward to press against the top of the product, thereby limiting the position of the product to prevent the product from shifting during the film application process and affecting the film application effect.
