[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0033] Figure 1 This is a structural schematic diagram of a display product of a COF (Chip-on-Foil) multi-directional densely distributed product type provided in an embodiment of this application. For example... Figure 1The image shows a semi-finished product 10 of a Flat Panel X-ray Detector (FPXD), which may include a detector panel. The detector panel can be of any shape. Figure 1 In one embodiment, the probe panel may have four sides, with its outer peripheral edge comprising four edges connected end-to-end in sequence. Exemplarily, the FPXD semi-finished product 10 (e.g., FPXD OC) may be a two-sided bonded COF (i.e., bidirectional COF), with one side being a gate integrated circuit (Gate IC) and the other side being a readout integrated circuit (ROIC). Alternatively, it may be a three-sided bonded COF (i.e., tridirectional COF), with one side being a gate integrated circuit (Gate IC) and the other two sides being readout integrated circuits (ROICs), for example... Figure 1 As shown.

[0034] Traditional slotted packaging structures 100, such as pallets or boxes, suffer from insufficient positioning area and difficulty in securing FPXD semi-finished products 10. This poses a risk of displacement during transport, potentially leading to COF bending, product failure, or surface scratches. Since multi-COF products are valuable, defects caused by transportation can result in significant losses. Furthermore, these COF products with densely distributed multi-directional distributions are typically produced in small quantities, often requiring single pieces. Using pallet or box packaging structures 100 necessitates mold making, which cannot meet the demands of rapid sample delivery.

[0035] Based on this, this application provides a COF (Chemical Oscillator) multi-directional densely distributed product sample packaging structure 100. It achieves adhesive-free product bonding and fixing (e.g., FPXD) through the electrostatic adsorption force generated on the surface of the electrostatic adsorption layer (e.g., PE electrostatic film). After removing the electrostatic adsorption layer, there is no residue on the product surface, and it can be used multiple times. Furthermore, it requires no mold opening fees, requiring only a one-time investment, and has the advantages of low cost.

[0036] The packaging structure 100 provided in this embodiment may include: a packaging box 20, wherein the packaging box 20 has an internal cavity; the cavity is used to hold the display product.

[0037] At least one electrostatic adsorption layer is disposed inside the packaging box 20 and located in the receiving cavity; the packaging structure 100 provides electrostatic adsorption force through the electrostatic adsorption layer to limit the display product.

[0038] In some of these embodiments, such as Figure 2 and Figure 5a As shown, the packaging box 20 may include a first plate 21 and a second plate 22 that are disposed opposite to each other and are rotatably connected; and a support member fixed to the first plate 21 to define the receiving cavity between the first plate 21 and the second plate 22. The display product may be disposed in the receiving cavity.

[0039] In some embodiments, the display product may be a flat panel X-ray detector, with at least one edge of the flat panel X-ray detector bonded to a COF.

[0040] In some embodiments, the second plate 22 is rotatably connected to the first plate 21, so that the second plate 22 can be flipped over and cover the first plate 21. For example... Figure 2 and Figure 3 As shown, in the first direction X, the first plate 21 and the second plate 22 are disposed opposite to each other. The first direction X is parallel to the plane where the display product is located, and the second direction Y is perpendicular to the first direction X. The first plate 21 has a first surface 211 opposite to the second plate 22, and the second plate 22 has a second surface 221 opposite to the first plate 21. In the second direction Y, the packaging box 20 may include four sides, which can be connected end to end in sequence. Figure 5b As shown, the four sides may include opposing first side 231 and second side 232, and opposing third side 233 and fourth side 234. The two ends of the third side 233 are respectively connected to one end of the first side 231 and the second side 232, and the two ends of the fourth side 234 are respectively connected to the other ends of the first side 231 and the second side 232. Figure 3 Taking the central position as an example, the first side 231 and the second side 232 are longitudinally extending sides on the left and right sides, respectively, while the third side 233 and the fourth side 234 are laterally extending sides on the top and bottom sides, respectively. Adjacent edge sides can be directly connected, or they can be smoothly connected through arcs, curves, etc. For example... Figure 3 , Figure 5a and Figure 6a As shown, the first plate 21 may include a first side 231a, a second side 232a, a third side 233a and a fourth side 234a; the second plate 22 may also include a first side 231b, a second side 232b, a third side 233b and a fourth side 234b.

[0041] In some embodiments, reference Figure 6b The at least one electrostatic adsorption layer is disposed on at least one of the first surface 211 opposite to the first plate 21 and the second plate 22, and the second plate 22 is disposed on at least one of the second surface 221 opposite to the first plate 21. That is, the electrostatic adsorption layer can be adsorbed onto at least one surface of the display product by electrostatic adsorption force, such as at least one of the upper and lower surfaces. For example, the at least one electrostatic adsorption layer can be a single layer, specifically disposed on the first surface 211 opposite to the first plate 21 and the second plate 22, or the second plate 22 disposed on the second surface 221 opposite to the first plate 21. The at least one electrostatic adsorption layer can also be two layers, specifically disposed on the first surface 211 opposite to the first plate 21 and the second plate 22 disposed on the second surface 221 opposite to the first plate 21. The at least one electrostatic adsorption layer can also be multiple layers, with at least one layer on the first surface 211 opposite to the first plate 21 and at least one layer on the second surface 221 opposite to the first plate 21.

[0042] In some embodiments, the at least one electrostatic adsorption layer includes a first electrostatic adsorption layer 241 and a second electrostatic adsorption layer 242. The first electrostatic adsorption layer 241 is disposed on a first surface 211 opposite to the first plate 21 and the second plate 22; the second electrostatic adsorption layer 242 is disposed on a second surface 221 opposite to the second plate 22 and the first plate 21. The first electrostatic adsorption layer 241 can be at least one layer; the second electrostatic adsorption layer 242 can also be at least one layer, the number of layers being determined according to the thickness of the display product. In this way, the electrostatic adsorption layers can be adsorbed onto the upper and lower surfaces of the display product by electrostatic adsorption force, better achieving the limitation of the display product in the first direction X.

[0043] In some embodiments, the thickness of the electrostatic adsorption layer (e.g., the first electrostatic adsorption layer 241 and the second electrostatic adsorption layer 242) can be 0.05mm-0.08mm, and the peel strength ≤5g / cm; 1×10 6 Ω≤ Surface resistance < 1×10 11 Ω; friction voltage <100V; materials include PE, PET, or PVC. This allows for adhesive-free bonding of the detection panel through the electrostatic adsorption force generated by the electrostatic adsorption layer. After removing the electrostatic adsorption layer, there is no residue on the surface of the FPXD semi-finished product 10, and it can be used multiple times.

[0044] In some embodiments, the electrostatic adsorption layer can be an existing electrostatic adsorption layer structure, or it can be a release film. For example... Figure 4 As shown, the electrostatic adsorption layer may include a substrate layer 243, an electrostatic liquid layer 244 disposed on the substrate layer 243, and an adhesive layer 245 disposed on the electrostatic liquid layer 244. The substrate layer 243 may be PE, PET, or PVC, etc. The adhesive layer 245 may be an acrylate copolymer. When the substrate layer 243 is PE or PET, it has the advantage of low cost. When the substrate layer 243 is PVC, it has advantages such as long service life and stability at high temperatures.

[0045] In some embodiments, the packaging structure 100 may further include at least one buffer layer. The buffer layer may be fixed within the packaging box 20 and located in the receiving cavity; the electrostatic adsorption layer is fixed to the side of the buffer layer away from the packaging box 20. That is, the buffer layer may be a single layer or multiple layers. When the buffer layer is a single layer, it may be fixed to a first surface 211 of the first plate 21 opposite to the second plate 22, or a second surface 221 of the second plate 22 opposite to the first plate 21. When the buffer layer is multiple layers, it may be fixed simultaneously to both the first surface 211 of the first plate 21 opposite to the second plate 22 and the second surface 221 of the second plate 22 opposite to the first plate 21. Providing a buffer layer can buffer the stress between the first plate 21 / second body and the display product, thereby preventing damage to the display product.

[0046] In some of these embodiments, please continue to refer to Figure 2 The at least one buffer layer may include a first buffer layer 251 and a second buffer layer 252. The first buffer layer 251 may be fixed (e.g., heat-pressed) to a first surface 211 opposite to the first plate 21 and the second plate 22, and the first electrostatic adsorption layer 241 may be fixed (e.g., glued) to the side of the first buffer layer 251 away from the first plate 21. The second buffer layer 252 may be fixed (e.g., heat-pressed) to a second surface 221 opposite to the first plate 21 and the second plate 22, and the second electrostatic adsorption layer 242 may be fixed (e.g., glued) to the side of the second buffer layer 252 away from the second plate 22.

[0047] In some embodiments, the thickness of the first buffer layer 251 is greater than the thickness of the second buffer layer 252 to better support the display product. The thickness of the first buffer layer 251 can be 7.8-8.2 mm, for example, 8 mm. The thickness of the second buffer layer 252 can be 6.3-6.7 mm, for example, 6.5 mm.

[0048] In some embodiments, the first buffer layer 251 and the second buffer layer 252 can both be made of EPE pearl cotton, with a foaming ratio of 38.8-40.2 times, for example, both can be 40 times.

[0049] In some embodiments, the support member may be a support frame 26. The receiving cavity is defined by the support frame 26. The surface resistance R of the support frame 26 can meet 1×10⁻⁶. 6 Ω≤R<1×10 11 Ω, friction voltage <100V, height, i.e., the dimension in the first direction X, can be about 15mm, the material can be EVA, and the foaming ratio is 9.8 to 10.2 times, for example 10 times, to buffer the stress between the first plate 21 / second body and the display product while defining the receiving cavity. The support frame 26 can be bonded to the first plate 21.

[0050] In some embodiments, the first plate 21 can be a hollow board; the second plate 22 can be a hollow board. The first plate 21 / second plate 22 can be a PP hollow board or a corrugated paper material. When the first plate 21 / second plate 22 is a corrugated paper material, it facilitates the manufacturing of the first plate 21 / second plate 22. When the first plate 21 / second plate 22 is a PP hollow board, it provides good toughness, flexible dimensions, and a long service life.

[0051] In some embodiments, the corrugated orientations of the first plate 21 and the second plate 22 are staggered to improve the strength of the packaging structure 100 and reduce the risk of deformation when subjected to external forces or impacts. For example, the corrugated orientations of the first plate 21 and the second plate 22 can be staggered at 90°. Exemplarily, the corrugated orientation of the first plate 21 is transverse (e.g., the second direction Y), and the corrugated orientation of the second plate 22 is vertical (e.g., the first direction X). The first plate 21 / second plate 22 can be PP hollow boards with a thickness of 6mm and a basis weight of 850g / m³. 2 .

[0052] In some of these embodiments, please refer to Figure 5a , Figure 5b , Figure 6a and Figure 6bThe packaging box body 20 may include connecting components. These connecting components can connect the four sides of the packaging structure 100, that is, connect the corresponding four sides of the first plate 21 and the second plate 22 to strengthen the sealing of the sides of the packaging structure 100. The second plate 22 can be fitted onto the first plate 21 via the connecting components.

[0053] In some embodiments, the connecting assembly may include a connecting hook and loop fastener 271 and a hook and loop fastener assembly. One side of the first plate 21 (e.g., first side 231a) and one side of the second plate 22 (e.g., first side 231b opposite to first side 231a) can be foldably connected via the connecting hook and loop fastener 271, allowing the second plate 22 to cover the first plate 21. The hook and loop fastener assembly may include a first hook and loop fastener 272 and a second hook and loop fastener 273 that engage with each other via a looped surface and a hook surface. The first hook and loop fastener 272 may be a hook surface, and the second hook and loop fastener 273 may be a looped surface. The first Velcro 272 may be disposed on the surface of the first plate 21 away from the second plate 22 (e.g., the third surface 212), and the second Velcro 273 may be disposed on the surface of the second plate 22 away from the first plate 21 (e.g., the fourth surface 222) to connect the remaining sides of the first plate 21 (e.g., the second side 232a / the third side 233a / the fourth side 234a) to the corresponding remaining sides of the second plate 22 (e.g., the second side 232b / the third side 233b / the fourth side 234b).

[0054] In some embodiments, the connecting hook and loop fasteners 271 may be provided in multiple ways; the hook and loop fastener components may also be provided in multiple ways; each side of the first plate 21 is provided with at least one first hook and loop fastener 272; and the corresponding side of the second plate 22 is provided with at least one second hook and loop fastener 273.

[0055] For example, refer to Figure 5a , Figure 5b as well as Figure 6a and Figure 6b As shown, the connecting hook and loop fasteners 271 can be set to 3, the first hook and loop fasteners 272 can be set to 4, and the second hook and loop fasteners 273 can also be set to 4. Specifically, 2 can be set on the second side, and 1 each on the third and fourth sides. It should be understood that more hook and loop fasteners (first hook and loop fasteners 272 / second hook and loop fasteners 273) can be set on the second, third, and fourth sides respectively.

[0056] In some embodiments, the connecting hook and loop fasteners 271, 272, and 273 can be made of nylon. The connecting hook and loop fasteners 271, 272, and 273 can be glued to their respective plates (first plate 21 or second plate 22).

[0057] In the preparation of the packaging structure 100 provided in this embodiment, a first plate 21 and a second plate 22 made of PP hollow board material are first prepared. Next, a second buffer layer 252 of EPE pearl cotton material is hot-pressed onto the second surface 221 of the second plate 22 of the PP hollow board material. Then, an acrylic low-temperature adhesive is applied to the upper surface of the second buffer layer 252 to bond a second electrostatic adsorption layer 242 of PE electrostatic film material. Then, polypropylene adhesive is applied to the first plate 21 of the PP hollow board material to bond a support frame 26 of EVA material. Next, the first buffer layer 251 of EPE pearl cotton material is hot-pressed into the receiving cavity surrounded by the support frame 26 in the first surface 211 of the first plate 21 of the PP hollow board material. Then, an acrylic low-temperature adhesive is applied to the surface of the first buffer layer 251 to bond the first electrostatic adsorption layer 241 of PE electrostatic film material. Then, three double-sided nylon Velcro fasteners are glued together at the middle of the first side 231a of the third surface 212 of the first plate 21 (without a hierarchical structure) and the first side 231b of the fourth surface 222 of the second plate 22 (without a hierarchical structure), making the first plate 21 and the second plate 22 rotatably connected. Next, one side of a single-sided fastener 272 is fixed to the second, third, and fourth sides of the third surface 212 of the first plate 21 (without a hierarchical structure), leaving the hook side of the fastener 272 suspended. One side of a single-sided fastener 273 is fixed to the corresponding positions on the second, third, and fourth sides of the fourth surface 222 of the second plate 22 (without a hierarchical structure), exposing the rough side of the fastener 273. Thus, the packaging structure 100 in the open state is obtained.

[0058] When packaging a product with a multi-directionally densely distributed COF, such as a semi-finished product 10 of FPXD, using the packaging structure 100, the semi-finished product 10 of FPXD is placed on the first electrostatic adsorption layer 241 of the first plate 21, and then the second plate 22 is placed on top of the semi-finished product 10 of FPXD. Multiple first hook and loop fasteners 272 are then sequentially attached to the corresponding second hook and loop fasteners 273, thus completing the packaging of the semi-finished product 10 of FPXD.

[0059] The packaging structure 100 provided in this application embodiment packages the FPXD semi-finished product 10 using a layered structure of PP hollow board, EVA support frame, EPE buffer layer, and PE electrostatic adsorption layer. The PE electrostatic adsorption layer can generate electrostatic adsorption force to fix the detector panel of the flat panel X-ray detector semi-finished product 10, which can reduce the displacement of the flat panel X-ray detector semi-finished product 10 during transportation and reduce damage to the COF on the side of the detector panel panel. At the same time, there is no dirt residue on the surface of the X-ray detector semi-finished product 10 after the packaging structure 100 is removed. It can improve the transportation safety of the X-ray detector semi-finished product 10, and also has the advantages of being aesthetically pleasing and easy to carry, which can meet the needs of customer scenarios such as small-batch sample delivery and display.
