Description

Technical Field

[0001] This utility model relates to the technical field of laminated passport pages, and more particularly to a laminated electronic passport information page inlay layer with smooth edges. Background Technology

[0002] The electronic passport information page is laminated with a PET hinge. Direct lamination results in severe material deformation, directly impacting product quality and appearance. This solution improves the lamination process to address quality issues such as edge deformation after laminating the electronic passport information page with the PET hinge.

[0003] The electronic passport data page is assembled from multiple layers of PC material, with PET hinges positioned between the PC layers. The binding process uses positioning holes as a reference to ensure accurate positioning of the PC materials during binding. Ultrasonic spot welding is used. After assembly, a laminate is placed inside for lamination. Because the multiple layers of PC and PET hinges require high-temperature lamination to fuse them together and form an effective bond, the product after high-temperature lamination is affected by temperature and pressure, causing material overflow and deformation. Only a cutting machine can be used to trim the deformed areas to ensure the product's straightness and appearance quality. However, the two long sides of the product cannot be trimmed due to the presence of PET hinges, as cutting would damage the PET hinges. Therefore, this new lamination solution can achieve a strong bond between the PET hinges and PC and effectively control material deformation caused by overflow. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 This is the first embodiment of the present invention, which provides a smooth-edged laminated electronic passport information page Inlay layer. This smooth-edged laminated electronic passport information page Inlay layer includes a guide line l drawn perpendicular to the plane, and multiple layers of material are arranged along the extension direction of the guide line l, which are laminated to form a passport page; the electronic passport information page Inlay layer is divided into a four-layer structure.

[0032] Along the extension direction of the guide line l, it includes, in sequence, a first protective layer 100, a compensation layer 200, a PET hinge layer 300, a buried wire layer 400, and a second protective layer 500.

[0033] The compensation layer 200 has a first positioning hole 201 and a first chip hole 202. The embedded wire layer 400 has a second positioning hole 401 corresponding to the first positioning hole 201 and a second chip hole 402 corresponding to the first chip hole 202.

A copper wire 403 is wound on the embedded wire layer 400. A chip 404 is disposed between the first positioning hole 201 and the second positioning hole 401. The first protective layer 100 and the second protective layer 500 have the same structure.

[0034] Example 2

[0035] Reference Figure 1This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the electronic passport data page consists of five material layers. The first protective layer 100 is 310mm long, 188mm wide, and 0.03mm thick. The compensation layer 200 is 310mm long, 188mm wide, and 0.15mm thick. The PET hinge layer 300 is 0.1mm thick, 20mm wide, and has a particle size of 150 mesh. The embedded wire layer 400 is 310mm long, 174mm wide, and 0.105mm thick. The chip 404 is 240mm thick.

[0036]

[0037]

[0038] The remaining structure is the same as that in Example 1.

[0039] Example 3

[0040] Reference Figure 1 This is the third embodiment of the present invention, which differs from the second embodiment in that, compared to embodiment 2, the invention applies to the steel plate of the electronic passport information page and the PET hinge layer 300 pressing. The steel plate has a length of 690mm, a width of 540mm, and a thickness of 0.8mm, and is suitable for four 2×2 sheets. The steel plate material is 430 stainless steel. Specifically, a laminated box has 11 steel plates. The first steel plate is the top plate, the second to tenth steel plates are the middle plates, and the eleventh steel plate is the bottom plate. The interlayer between two steel plates serves as the lamination area. The steps on the laminated plates are dams. The dams above the top plate and the bottom plate have the same size and height, with a width of 20mm, a height of 0.17mm on the front (A side), a height of 0.13mm on the back (B side), and a double-sided roughness of Ra0.5±0.1μm. The central dam at the top of the middle plate is 40mm wide, with a height of 0.17mm on side A and 0.13mm on side B, and a double-sided roughness Ra of 0.5±0.1μm. Through a special design of the laminated steel plate, using the raised dam on the laminated plate, the problem of material deformation and overflow of PC material after high-temperature lamination is prevented, providing effective quality assurance for the lamination of the electronic passport information page inlay layer and the 300 PET hinge layer.

[0041] The rest is the same as in Example 2.

[0042] Example 4

[0043] Reference Figure 1This is the fourth embodiment of the present invention, which differs from the third embodiment in that it provides a manufacturing process for a laminated electronic passport information page Inlay layer with smooth edges. The process includes the following steps: using a drilling machine to drill chip holes and positioning holes in the compensation layer 200 and the embedded wire layer 400; importing the layout drawing into the drilling machine; placing the compensation layer 200 and the embedded wire layer 400, which require the drilling of chip holes and positioning holes, on the drilling machine platform, ensuring that the compensation layer 200 and the embedded wire layer 400 are in close contact with the positioning points to ensure accurate positioning; setting the drilling depth of the drilling machine according to the material thickness; clicking start to start the equipment for drilling; after drilling is completed, cleaning up the waste material and checking the drilling effect to see if it meets the quality requirements.

[0044] Use the 400 embedded wire layer for winding, install the copper wire on the embedded wire machine and pass it through the ultrasonic embedded wire head. Place the embedded wire layer 400 with the chip hole pre-drilled on the embedded wire platform according to the positioning requirements, open the embedded wire program, start the embedded wire equipment, and begin embedded wire. After the embedded wire is completed, check the product quality. No broken wires or loose wires are allowed.

[0045] Chip 404 is attached between the first chip hole 202 and the second chip hole 404 and fixed by welding with a spot welding machine. A layer of tape is applied to the compensation layer 200 and the buried wire layer 400, which have already been made with chip holes, at the positions of the first chip hole 202 and the second chip hole 402 to fix the chip. The chip is then attached to the compensation layer 200 and the buried wire layer 400 with tape, and the chip 404 is welded to the copper wire 403 using a welding machine. After welding, the solder joints are checked for any signs of poor soldering.

[0046] The PET hinge layer 300 is bound together with the compensation layer 200, the embedded wire layer 400, the first protective layer 100, and the second protective layer 500. Using an ultrasonic welding head, the PET hinge layer 300 is fixed on top of the compensation layer 200 and the embedded wire layer 400. The PET hinge layer 300 should be placed between the compensation layer 200 and the embedded wire layer 400. The exposed width of the PET hinge layer 300 is 13mm, and the bonding width with the compensation layer 200 and the embedded wire layer 400 is 7mm. A transparent protective layer is added to both outer sides of the compensation layer 200 and the embedded wire layer 400. A first protective layer 100 is added to the outside of the compensation layer 200, and a second protective layer 500 is added to the outside of the embedded wire layer 400. The PET hinge layer 300 is then fixed using an ultrasonic welding head.

[0047] The bound electronic passport information page is placed on the laminar flow liner according to the pre-set positioning requirements. The PET hinge layer at position 300 is tightly fitted against the dam on the laminar flow liner to prevent material overflow after lamination and deformation of the hinge position of the electronic passport information page. The laminar flow liner is then turned on, and the laminar flow liner parameters are set to high temperature 180°C for 20 minutes, with a pressure value of 180 N / cm². 2The product is then laminated. After lamination, a cutting machine is used to trim the deformed areas on the short sides of the product.

[0048] The remaining structure is the same as that in Example 3.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
