[0002] In the production and manufacturing of vehicle-mounted screens, the surface of the glass screen is provided with functional films and protective films, and the shape and size of the diaphragm are designed to be similar to those of the glass screen. According to the current development of vehicle-mounted interiors, large-size and curved screens are gradually becoming the development trend in the future. The current film cutting equipment only cuts films, for example, the application number 201810813010.5 and the application name are "numerical control machine tool specially used for screen diaphragm processing".

[0003] In order to ensure that the size of various diaphragms produced meets the design requirements of drawings, a large two-dimensional equipment is usually used to establish a coordinate system for the diaphragm to measure the size at multiple points. Among them, the conventional rectangular diaphragm is manually operated, and the length and width can be simply measured. The main problem is that the products with irregular edges and the whole periphery are often established by grabbing the longest and widest points to make a straight line and then equally dividing the center point. The error of manual visual recognition often causes the deviation of the established center point, thereby affecting the measurement of each point size, and causing waste of personnel and resources for diaphragm manufacturers and downstream users. CONTENT OF THE UTILITY MODEL

[0004] One of the technical problems to be solved by the application is that the center point of the use layer of the diaphragm assembly is not accurately grabbed due to human measurement error.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. When it is described that a specific device is located between the first device and the second device, there can be or can not be an intermediate device between the specific device and the first device or the second device.

[0028] All the terms used in the present application have the same meaning as understood by those skilled in the art to which the present application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted to have meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or excessively formalized sense, unless specifically defined here.

[0029] The techniques, methods, and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and devices should be considered as part of the specification.

[0030] As shown in Figure 1 and Figure 2 Embodiment one shows a film processing device, which includes a base assembly 10 and a cutter assembly 20. The base assembly 10 includes a base platform structure, a mounting bracket structure mounted on the upper part of the base platform structure, and a hydraulic structure with a hydraulic cylinder mounted on the mounting bracket structure, the hydraulic structure being located on the upper part of the base platform structure, and the piston shaft of the hydraulic structure being perpendicular to the base platform structure. The cutter assembly 20 includes a mounting structure 21, a first cutter 22, a second cutter 23, and a third cutter 24, the upper side of the mounting structure 21 being connected to the piston of the hydraulic structure, the first cutter 22, the second cutter 23, and the third cutter 24 all being mounted on the lower side of the mounting structure 21, the second cutter 23 being located between the first cutter 22 and the third cutter 24, and the number of the second cutter 23 being greater than or equal to three.

[0031] By applying the technical solution of embodiment one, the hydraulic structure drives the cutter assembly 20 to press down the film assembly, the first cutter corresponds to the cutting of the bottom film layer 30, the second cutter 23 cuts on the bottom film layer 30, and the third cutter 24 cuts the cover film layer 50 and the use layer 40 of the film assembly, so that the cutting of the film assembly and the cutting of the positioning trace are completed at one time. The cutting of the positioning trace is relatively uniform, without human measurement error, so that the measurement reference of the film assembly in the future is relatively accurate. The technical solution of embodiment one effectively solves the problem of human measurement error and the inaccuracy of the center point of the use layer of the film assembly.

[0032] It should be noted that the three second cutters 23 cut the three positioning marks, and the connecting line of the three positioning marks can establish a coordinate system. The coordinate system is more accurate and has no relative position error. The embodiment one establishes a rectangular coordinate system, the bottom is on the same straight line, two points of which form the X axis, one of which forms the Y axis in the vertical direction, and the common point is the origin. Other coordinate systems can also be established. In order to be more convenient and have stronger universality, the embodiment one establishes a rectangular coordinate system.

[0033] As shown in Figure 1 and Figure 2 In the technical scheme of the embodiment one, the cross section of the first cutter 22 is a rectangular ring, and the second cutter 23 is four, which are located at the four corners of the first cutter 22. The structure of the four second cutters 23 is easier to operate. More points, such as five second cutters 23, will cause an increase in installation cost and a decrease in installation efficiency. Three second cutters 23 will lead to difficulty in establishing a rectangular coordinate system after the workpiece is placed upside down.

[0034] As shown in Figure 2 In the technical scheme of the embodiment one, the distance between the lower edge of the first cutter 22 and the lower edge of the second cutter 23 is H1, which is between 1 / 3 and 3 / 4 of the thickness of the bottom film layer 30 of the diaphragm. The second cutter 23 is too long or too short, which is not suitable. The embodiment one adopts that H1 is 1 / 2 of the thickness of the bottom film layer 30 of the diaphragm. For example, the second cutter 23 is as high as the first cutter 22, which will cut off the bottom film layer 30 in the positioning hole, causing debris pollution. The structure is related to the cross section of the second cutter 23, which is a circular ring. The cross section of the second cutter 23 can be a semicircular ring, which can avoid the pollution of debris generated during cutting.

[0035] As shown in Figure 2As shown, in the technical solution of Embodiment 1, the distance between the lower edge of the second cutter 23 and the lower edge of the first cutter 22 is H2, and H2 is the same as the sum of the thickness of the cover layer 50 and the thickness of the use layer 40 of the diaphragm. The structure of the cutter assembly 20 described above can ensure that the cutting of the bottom film layer 30, the use layer 40 and the cover layer 50 achieves the appropriate effect. It should be noted that the adjustment of the position and distance of the first cutter 22, the second cutter 23 and the third cutter 24 is performed during installation. During the cutting process, the travel position of the hydraulic structure also needs to be adjusted. The diaphragm processing device also includes a control component, which is electrically connected to the solenoid valve on the hydraulic structure. When the control component is opened, the solenoid valve opens, and the hydraulic structure is connected. Through experiments, a cutting time of 3.5 seconds just meets the requirements, so the control component can be input to open the solenoid valve for 3.5 seconds. Of course, a manual operation method can also be used. The hydraulic structure can be operated by an experienced operator. The operator opens the hydraulic structure, the cutter assembly 20 cuts, and the operator operates the hydraulic structure to return it to its upward position.

[0036] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the lower end of the second cutter 23 has a circular cross-section. The circular cross-section of the lower end of the second cutter 23 makes positioning more convenient and makes it easier to find the center.

[0037] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the diameter of the ring is between 3mm and 6mm. This diameter causes less damage to the bottom film layer 30 and also makes it easier to find the center of the ring; even if there is a slight deviation in finding the center, it is within the allowable error range. In Embodiment 1, the diameter of the ring is 4mm.

[0038] In the technical solution of Embodiment 1, the mounting structure 21 includes a mounting plate with a mounting groove. The upper end of the second cutter 23 is disposed in the mounting groove, and the second cutter 23 is connected to the mounting plate by adhesive. The above structure is easy to assemble and disassemble. It should be noted that the heights of the first cutter 22, the second cutter 23, and the third cutter 24 are measured before adhesive bonding is applied.

[0039] The difference between the technical solution of Embodiment 2 and Embodiment 1 is that the mounting structure 21 includes a mounting plate with multiple threaded holes on its lower side. The upper part of the second cutter 23 has external threads that match the threaded holes, and the second cutter 23 mates with the threaded holes. This structure makes it easy to adjust the height of the second cutter 23 by rotating it.

[0040] like Figure 3 and Figure 4As shown, according to the technical solution of this application, a diaphragm assembly is also provided. The diaphragm assembly is processed by the aforementioned diaphragm processing device. The diaphragm assembly includes, from bottom to top, a bottom film layer 30, a service layer 40, and a cover film layer 50. In the vertical direction, the projections of the service layer 40 and the cover film layer 50 are both located within the projection of the bottom film layer 30. The bottom film layer 30 has three or more positioning holes 31. The lines connecting any two positioning holes 31 can form a rectangular coordinate system. By establishing a rectangular coordinate system, the center position of the diaphragm assembly and the various positions of the diaphragm assembly are determined. In the technical solution of this application, the depth of the positioning holes 31 is 1 / 4 to 2 / 3 of the depth of the bottom film layer 30. In this embodiment, the depth of the positioning holes 31 is 1 / 2 of the depth of the bottom film layer 30.

[0041] In summary, the diaphragm assembly consists of three layers of the same material with different thicknesses, from top to bottom: a cover film layer (PET), a service layer (nano-level optical coating + PET + anti-static polyurethane adhesive + bottom film layer (PET)). Furthermore, to facilitate easy removal of the bottom film layer when using the cover glass product, the bottom film layer 30 and the service layer 40 are staggered in layers.

[0042] The blade path method on the die-cutting mold, among which Figure 3 The upper outline solid line represents the geometric shape of the layer 40, the lower square represents the area shape and size of the bottom film layer 30, and the four positioning holes 31 are the dimensions of the 4mm diameter round hole knife marks. The knife assembly 20 is laid on the knife mold carrier plate (mounting structure 21) by the knife mold processing equipment according to the geometric dimensions and positions of the film layer assembly and the positioning holes 31 in accordance with the pre-designed drawings.

[0043] H2 represents the depth difference between the layer cutting tool and the bottom film cutting tool. To ensure that the bottom film is cut by the corresponding cutting tool, and the layer cutting tool just touches the bottom film, the value of H2 should be set to the thickness of the bottom film. The common thickness of the bottom film in the industry is 80 μm. The specific value can be determined according to the product parameters of different film material manufacturers.

[0044] The cutting tools at the 4mm diameter circular hole positions of the four positioning holes need to leave a cutting mark on the bottom film layer after achieving the aforementioned punching effect of the working layer + bottom film layer, without cutting through the circular holes on the bottom film layer. Therefore, the depth difference of H1 should be set to less than half the thickness of the bottom film layer. In this way, after punching, a circular hole mark will be left on the bottom film layer, and the film material inside the circular hole will be linked to the entire bottom film as a whole, thus avoiding the cumbersome problem of generating and discharging excess waste material from the four circular holes.

[0045] The positions of the four positioning holes can be generated by diagonal endpoints based on the center point of the layer in use of the diaphragm assembly.

[0046] So far, the embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.

[0047] Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified or some technical features can be replaced equivalently without departing from the scope and spirit of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
