[0051] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0052] Example 1

[0053] See also Figure 1-10 The technical solution of an arched film pressing assembly provided in this embodiment includes the following:

[0054] The film pressing plate group 1 includes an upper film pressing plate 11 arranged on the lower bottom surface of the upper film pressing device 51 and a lower film pressing plate 12 arranged on the upper bottom surface of the lower film pressing device 52;

[0055] The control slope 2 includes a first control slope 21 and a second control slope 22, wherein the first control slope 21 is symmetrically arranged at two ends of the upper bottom surface of the upper pressing film plate 11, and the second control slope 22 is symmetrically arranged at two ends of the lower bottom surface of the lower pressing film plate 12;

[0056] The locking member 3 includes a first locking member 31 and a second locking member 32, wherein the first locking member 31 penetrates the upper film pressing plate 11 to fix the upper film pressing plate 11 with the upper film pressing device 51, and the second locking member 32 penetrates the lower film pressing plate 12 to fix the lower film pressing plate 12 with the lower film pressing device 52;

[0057] When the first control slope 21 fits the upper film pressing device 51 , a first pressing convex portion 41 is formed in the middle of the upper film pressing plate 11 ; when the second control slope 22 fits the lower film pressing device 52 , a second pressing convex portion 42 is formed in the middle of the lower film pressing plate 12 .

[0058] In a specific implementation, the film pressing plate group 1 itself has toughness, and the upper film pressing plate 11 and the lower film pressing plate 12 will gradually fit and clamp the adhesive film during operation. Due to the existence of the first pressing protrusion 41 and the second pressing protrusion 42, at the beginning of the bonding process, the first pressing protrusion 41 and the second pressing protrusion 42 will first contact and clamp the middle part of the adhesive film to achieve fixation; in the process of continued pressurized bonding, taking the upper film pressing plate 11 as an example, the area near the first pressing protrusion 41 on the lower bottom surface of the upper film pressing plate 11 to the edge area will gradually fit, so as to achieve the fixation of the middle part of the adhesive film first, and then extension and pressing, so as to reduce wrinkles in the adhesive film.

[0059] Specifically, Figure 3 As shown, the middle part of the upper bottom surface of the upper pressing film plate 11 is concave downward to form a first hollow part 111, and the middle part of the lower bottom surface of the lower pressing film plate 12 is concave upward to form a second hollow part 121;

[0060] A plurality of first cutting guide grooves 112 are provided at the lower bottom surface of the upper pressing plate 11 and the corresponding area of ​​the first hollow portion 111 , and a plurality of second cutting guide grooves 122 are provided at the upper bottom surface of the upper pressing plate 11 and the corresponding positions of the first cutting guide grooves 112 .

[0061] In a specific implementation, the number of the first cutting guide grooves 112 and the second cutting guide grooves 122 is related to the number of blades in the cutter wheel assembly 53 in an actual cutting device.

[0062] Specifically, one end of the first control inclined surface 21 is connected to the upper bottom surface of the first hollow portion 111, and the other end is connected to the side wall of the upper film pressing plate 11 (that is, the two first control inclined surfaces 21 are respectively connected to the upper bottom surface of the first hollow portion 111). Figure 3 lower left and lower right tilt in );

[0063] One end of the second control slope 22 is connected to the lower bottom surface of the second hollow portion 121, and the other end is connected to the side wall of the lower pressure film plate 12 (that is, the two first control slopes 21 are respectively facing the lower surface of the second hollow portion 121). Figure 3 upper left and upper right tilt in the image).

[0064] In a specific implementation, the inclination of the control slope 2 should not be too large, otherwise when the control slope 2 is gradually fitted with the film pressing plate, the middle part of the film pressing plate will be arched too much, resulting in the inability to compact a whole film; similarly, the inclination angle should not be too small, otherwise the film pressing plate itself has toughness and the middle part cannot form a bulge, so as shown in the attached Figures 4 to 6 As shown in the figure, the angle between the first control slope 21 and the upper bottom surface of the upper film pressing plate 11 is controlled to be 5° to 10°. Figures 7-9 As shown, the angle between the second control slope 22 and the lower bottom surface of the lower pressure film plate 12 is optimally controlled to be 5° to 10°.

[0065] Specifically, the first locking members are in two groups, each group of the first locking members is provided with at least two, and the positions of the two groups of the first locking members correspond to the two first control inclined surfaces 21 respectively;

[0066] The second locking members are divided into two groups, each group includes at least two second locking members, and the positions of the two groups of second locking members correspond to the two second control slopes 22 respectively.

[0067] In a specific implementation, each set of locking members is evenly arranged along the side of the film pressing plate. For example, if each set of first locking members is provided with two, the two first locking members are symmetrically arranged along the side wall of the lower bottom surface of the upper film pressing plate 11, so as to evenly fix the two ends of the short side of the upper film pressing plate 11. Specifically, the first locking member and the second locking member are both cylindrical head screws.

[0068] Specifically, when the two sets of the first locking members are tightened, the two first control slopes 21 are pressed upward to fit toward the upper film pressing device 51, and the two ends of the upper film pressing plate 11 are tilted upward, and the middle of the upper film pressing plate 11 is bulged downward to form a first pressing convex portion 41;

[0069] When the two sets of the second locking members are tightened, the two second control slopes 22 are pressed downward to fit in the direction of the lower pressing film device 52 , the two ends of the lower pressing film plate 12 are pressed downward, and the middle part of the lower pressing film plate 12 bulges upward to form a second pressing protrusion 42 .

[0070] Example 2

[0071] As attached Fig.10As shown, the utility model further proposes a cutting device, including an upper film pressing device 51, a lower film pressing device 52, a cutter wheel assembly 53, a driving assembly and the arched film pressing assembly described in Example 1.

[0072] In a specific implementation, the driving component may be a cylinder, etc.;

[0073] Specifically, the upper film pressing device 51 includes a fixed block 511 and a suspended block 512 connected by a guide column 6, the top of the fixed block 511 is connected to the driving assembly, and the fixed block 511 can move away from or close to the suspended block 512 along the guide column 6;

[0074] The upper film pressing plate 11 is arranged at the bottom of the suspension block 512, and the lower film pressing plate 12 is arranged at the top of the lower film pressing device 52;

[0075] The cutter wheel assembly 53 is fixedly connected to the fixing block 511 , the upper half of the cutter wheel assembly 53 is accommodated in the fixing block 511 , and the lower half of the cutter wheel assembly 53 is accommodated in the first hollow portion 111 .

[0076] The working principle or working process of an arched film pressing component provided by the utility model is as follows:

[0077] Lay the film flat on the lower film pressing plate 12, start the driving assembly, and drive the upper film pressing device 51 to move downward as a whole;

[0078] The suspension block 512 in the upper film pressing device 51 will first contact the lower film pressing plate 12, that is, the upper film pressing plate 11 at the bottom of the suspension block 512 will first contact the lower film pressing plate 12. During the pressing and contacting process between the upper film pressing plate 11 and the lower film pressing plate 12, the first pressing convex portion 41 and the second pressing convex portion 42 will first contact the middle of the fixed adhesive film, and then the surrounding area of ​​the pressing convex portion to the edge area of ​​the film pressing plate will be gradually clamped and fitted;

[0079] When the floating block is completely fitted with the lower film pressing device 52, because the cylinder is still working, the fixed block 511 drives the cutter wheel assembly 53 to continue to move downward along the guide column 6, and the blade of the guide wheel assembly passes through the first cutting guide groove 112, the film and the second cutting guide groove 122 to achieve cutting of the film;

[0080] After the cutting is completed, the driving assembly is started to move the upper film pressing device 51 to separate the upper film pressing device 51 from the lower film pressing device 52, and the cut film is taken out, and the cutting is completed.

[0081] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
