[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an automatic film pressing mechanism includes an upper film pressing head 2 and a lower fixture base 11 for accommodating products. The top of the upper film pressing head 2 is provided with a film pressing drive 1 for driving the upper film pressing head 2 to move, and a pressing module is provided inside the upper film pressing head 2.

[0025] The lower fixture base 11 is provided with a positioning fixture module corresponding to the pressing module. The positioning fixture module includes multiple product cavities 9 opened inside the lower fixture base 11, and multiple lower fixture guide posts 7 are fixedly installed on the top of the lower fixture base 11. Multiple film-applying positioning posts 10 are provided outside the product cavities 9. The film-applying positioning posts 10 are fixedly installed on the lower fixture base 11. The pressing module is provided with sleeve holes 8 and positioning holes 12 corresponding to the lower fixture guide posts 7 and the film-applying positioning posts 10.

[0026] In this embodiment, the product to be coated is placed inside the product cavity 9. When the pressing module moves downward under the action of the pressing drive 1, the lower fixture guide post 7 and the film-coating positioning post 10 on the positioning fixture module correspond to the pressing module, ensuring that the pressing module maintains precise coaxiality with the positioning fixture module during the downward movement. At the same time, the pressing module makes the entire pressing process more stable and smooth, reducing impact and vibration.

[0027] As one implementation method, such as Figure 2 , Figure 3 and Figure 4 As shown, the pressing module includes a guide sleeve 3 fixedly installed at the bottom of the upper pressing head 2. Multiple sets of slots 6 are arrayed inside the guide sleeve 3. Multiple sets of floating pressing heads 4 are slidably installed inside the slots 6. The floating pressing heads 4 are used to position the film. An elastic element 5 is provided at the top of the floating pressing head 4.

[0028] Both the sleeve hole 8 and the positioning hole 12 are located at the bottom end of the guide sleeve 3.

[0029] In this embodiment, the pressing module has multiple independently moving floating pressure heads 4. Each floating pressure head 4 provides a constant pressing force through the internal elastic element 5 when pressing the film downward, so that each pressure head can independently adapt to the micro-unevenness of the product surface, ensuring uniform pressure distribution on the entire pressing surface. Furthermore, the sleeve hole 8 and positioning hole 12 on the pressing module cooperate with the lower fixture guide post 7 and film-applying positioning post 10 set on the positioning fixture module to form a mold closing guide, ensuring that the pressing module maintains precise coaxiality with the positioning fixture module during the downward movement, and preventing off-center loading.

[0030] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, the elastic element 5 is one of an airbag, a hydraulic damper, or a disc spring.

[0031] In this embodiment, by employing different elastic elements 5, a completely uniform surface pressure is provided to the floating pressure head 4, which is suitable for extremely uneven surfaces.

[0032] As one implementation method, such as Figure 1 and Figure 4 As shown, the top ends of the lower fixture guide post 7 and the film-applying positioning post 10 are both cone-shaped.

[0033] In this embodiment, the lower jig guide post 7 and the sleeve hole 8 are matched to ensure that there is no deviation during the pressing process and improve the pressing accuracy. The film-applying positioning post 10 is used to accurately position the initial position of the film. At the same time, the tapered surface is set at the end of the lower jig guide post 7 and the entrance of the film-applying positioning post 10 to achieve self-centering and prevent jamming and wear during initial contact.

[0034] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, the pressure diaphragm drive 1 is one of a pneumatic cylinder, an electric servo cylinder, or a hydraulic cylinder.

[0035] In this embodiment, more precise pressure and position control can be achieved through different servo drives, such as pneumatic cylinders, electric servo cylinders, or hydraulic cylinders.

[0036] As one implementation method, such as Figure 2 and Figure 4 As shown, guide sleeve 3 and lower fixture base 11 are provided with guide slopes on opposite sides.

[0037] In this embodiment, during the mold closing process, when the pressing mold assembly moves downward under the action of the pressing film drive 1, the guide slope of the guide sleeve 3 first contacts the guide surface on the lower fixture base 11. Through the interaction of the slopes, even if there is a certain horizontal position deviation between the upper and lower molds, it can be automatically corrected under the action of the slope guide force, thus realizing the radial self-centering function.

[0038] As one implementation method, such as Figure 2 and Figure 4 As shown, at least five sets of floating pressure heads 4 are provided, and the bottom end of the floating pressure head 4 is set as a guide slope.

[0039] In this embodiment, multiple independently moving floating pressure heads 4 allow each pressure head to independently adapt to the microscopic unevenness of the product surface as the pressing module moves downward, ensuring uniform pressure distribution across the entire pressing surface.

[0040] Working principle: During use, the product to be laminated is placed inside the product cavity 9. When the pressing module moves downward under the action of the pressing drive 1, the multiple independently moving floating pressure heads 4 in the pressing module provide a constant pressing force through the internal elastic element 5 when pressing the film downward. This allows each pressure head to independently adapt to the micro-unevenness of the product surface, ensuring uniform pressure distribution across the entire pressing surface. Furthermore, the sleeve hole 8 and positioning hole 12 on the pressing module cooperate with the lower fixture guide post 7 and the film-applying positioning post 10 on the positioning fixture module to form a mold closing guide, ensuring that the pressing module maintains precise coaxiality with the positioning fixture module during the downward movement and preventing off-center loading.

[0041] Meanwhile, when the pressing module moves downward under the action of the pressing drive 1, the guide slope of the guide sleeve 3 first contacts the guide surface on the lower fixture base 11. Through the interaction of the slopes, even if there is a certain horizontal position deviation between the upper and lower molds, it can be automatically corrected under the action of the slope guide force, thus realizing the radial self-centering function.
