AI Technical Summary
The existing fully open steel plate has the problem that ink flow and strength cannot be satisfied at the same time. The existing design uses wire diameters of the connecting bridge. A thinner wire diameter gives the reinforced area better ink flow but insufficient strength, while a thicker wire diameter gives the reinforced area greater strength but unstable ink flow.
A fully open steel plate with gradient hybrid bridging is designed. By setting connecting bridges of different lengths at different locations in the reinforced zone, the connecting bridges are the longest in the rectangular zone and gradually decrease in length in the gradient zone and the overlapping zone, so as to balance ink resistance and strength.
This achieves the goal of improving the structural strength of the steel plate while satisfying ink transfer requirements, preventing breakage, and extending the service life of printing equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of solar cell printing technology, and in particular to a gradient hybrid bridging fully open steel plate and printing steel plate. Background Technology
[0002] Fully open steel plates are a new type of metal plate used in solar cell printing technology. The open area directly penetrates the material, forming a completely open channel for printing conductive paste, allowing a long grid to be formed on the surface of the cell in one go.
[0003] To ensure the integrity of the printing plate, a fully open steel plate has notches at certain locations corresponding to the fine grid lines. Therefore, each printed grid line will have gaps, requiring a second printing with another steel plate to fill these gaps and complete the printing of the final image. To ensure strength, existing technologies such as CN120096225A use two metal layers with a reinforcing zone on the upper layer, and connecting bridges within this reinforcing zone to improve structural strength.
[0004] The existing design uses a consistent wire diameter for the connecting bridge. However, in practice, it has been found that a thinner wire diameter results in better ink flow in the reinforced area, but insufficient strength; while a thicker wire diameter results in greater strength in the reinforced area, but unstable ink flow.
[0005] In view of this, it is necessary to improve the existing fully open steel plates to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a fully open steel plate with gradient hybrid bridging to solve the problem that existing fully open steel plates cannot simultaneously meet the requirements of ink transfer and strength.
[0007] To achieve the above objectives, the fully open steel plate of this utility model with gradient hybrid bridging includes a first metal layer, on which multiple printing channels are arranged side by side. Each printing channel includes multiple ink penetration channels spaced apart along the extension direction and a reinforcing zone disposed between two adjacent ink penetration channels. The reinforcing zone includes multiple spaced connecting bridges, with ink penetration holes formed between two adjacent connecting bridges. The reinforcing zone includes two overlapping areas of the printing slots on both sides, two gradient areas of the adjacent overlapping areas, and a rectangular area adjacent to the gradient areas on both sides. The ink penetration holes in the rectangular area have the same width along the perpendicular direction of the printing direction. The width of the ink penetration holes in the gradient areas and the overlapping areas gradually decreases towards the adjacent ink penetration channels along the perpendicular direction of the printing direction. The length of the connecting bridges in the rectangular area along the printing direction is greater than the length of the connecting bridges in the gradient areas and the overlapping areas along the printing direction.
[0008] As a further improvement of this utility model, the gradient hybrid bridging fully open steel plate includes a second metal layer, the first metal layer is stacked on top of the second metal layer, the second metal layer is provided with a plurality of printing slots for printing the entire fine grid in the vertical direction, the plurality of printing slots are arranged side by side, the printing slots extend along the printing direction, each printing channel is correspondingly arranged with one printing slot, and the pulp passage hole is located above the printing slot in the vertical direction.
[0009] As a further improvement of this utility model, the length of the connecting bridge in the gradient zone along the printing direction is greater than the length of the connecting bridge in the overlapping zone along the printing direction.
[0010] As a further improvement of this utility model, the width of the connecting bridges in the rectangular area along the perpendicular direction of printing is the same and is greater than the width of the ink penetration channel along the perpendicular direction of printing.
[0011] As a further improvement of this utility model, the length of the rectangular area along the printing direction is greater than the lengths of the gradient area and the overlapping area along the printing direction.
[0012] As a further improvement of this utility model, the length of the connecting bridge in the rectangular area along the printing direction is between 11 micrometers and 16 micrometers.
[0013] As a further improvement of this utility model, the length of the connecting bridge in the gradient area and the overlapping area along the printing direction is between 6 micrometers and 12 micrometers.
[0014] As a further improvement of this utility model, the length of the connecting bridge in the gradient area and the overlapping area is the same along the printing direction.
[0015] As a further improvement of this utility model, the lengths of the connecting bridges in the gradient area and the overlapping area are different along the printing direction.
[0016] This utility model also provides a printing device, which includes a frame, an ink supply mechanism, a pad printing mechanism, and a fully open steel plate with gradient hybrid bridging as described above.
[0017] The beneficial effects of this utility model are: the fully open steel plate and printing equipment of this utility model with gradient hybrid bridging can take into account both ink flow and strength by setting different lengths of the connecting bridges at different positions in the reinforcement zone, and is not easy to break while satisfying the ink flow requirement.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0022] like Figures 1 to 2 As shown, the fully open steel plate 100 of the gradient hybrid bridging of this utility model includes a first metal layer 1.
[0023] The first metal layer 1 has a plurality of printing channels 2 arranged in parallel. The printing channels 2 include a plurality of paste-permeable channels 3 arranged at intervals along the extension direction and a reinforcing area 4 arranged between two adjacent paste-permeable channels 3.
[0024] One side of the first metal layer 1 is in direct contact with the scraper.
[0025] The reinforcing zone 4 includes multiple spaced connecting bridges 6, with a through hole 5 formed between two adjacent connecting bridges 6. The reinforcing zone 4 includes two overlapping areas 41 on adjacent sides of the printing slot, two gradient areas 42 on adjacent overlapping areas 41, and a rectangular area 43 adjacent to the gradient areas 42 on both sides. The overlapping areas 41, gradient areas 42 and rectangular area 43 all have through holes 5 and connecting bridges 6.
[0026] The connecting bridge 6 can be cylindrical or have a rectangular or circular cross-section.
[0027] In this embodiment, the rectangular area 43 is located in the middle, and the two sides are the gradient area 42 and the overlapping area 41 respectively.
[0028] In the rectangular area 43, the width of the ink penetration holes 5 along the perpendicular direction of printing is the same, and the width of the ink penetration holes 5 in the gradient area 42 and the overlapping area 41 gradually decreases towards the adjacent ink penetration channel 3 along the perpendicular direction of printing.
[0029] The gradient area 42 and the overlapping area 41 have no clear boundary. The gradient area 42 is close to the rectangular area 43, and the overlapping area 41 is close to the ink penetration channel 3. The width of the ink penetration holes 5 in the gradient area 42 and the overlapping area 41 gradually decreases towards the adjacent ink penetration channel 3. Preferably, the gradient area 42 and the overlapping area 41 are set to have the same or similar length along the printing direction.
[0030] The length of the connecting bridge 6 within the rectangular area 43 along the printing direction is greater than the length of the connecting bridge 6 within the gradient area 42 and the overlapping area 41 along the printing direction. Here, the length of the connecting bridge 6 refers to the length of its orthographic projection along the vertical direction along the printing direction.
[0031] In this embodiment, the length of the connecting bridge 6 in the rectangular area 43, which is subjected to the greatest stress and is most prone to breakage, is set to be larger, so that it can withstand greater pressure. On the other hand, the length of the connecting bridge 6 in the gradient area 42 and the overlapping area 41 is set to be smaller, so that ink flow can be improved.
[0032] In this embodiment, the gradient hybrid bridging fully open steel plate 100 includes a second metal layer, the first metal layer 1 is stacked on top of the second metal layer, the second metal layer is provided with a plurality of printing slots for printing the entire fine grid in the vertical direction, the plurality of printing slots are arranged side by side, the printing slots extend along the printing direction, each printing channel 2 is corresponding to one printing slot, and the pulp through hole 5 is located above the printing slot in the vertical direction.
[0033] In this embodiment, the length of the connecting bridge 6 in the gradient area 42 along the printing direction is greater than the length of the connecting bridge 6 in the overlapping area 41 along the printing direction. Since the gradient area 42 is located between the overlapping area 41 and the rectangular area 43, the connecting bridge 6 in the gradient area 42 needs to balance ink flow and strength.
[0034] The width of the connecting bridges 6 within the rectangular area 43 is the same along the direction perpendicular to the printing direction, and is greater than the width of the ink penetration channel 3 along the direction perpendicular to the printing direction.
[0035] In this embodiment, the widths of the connecting bridge 6 and the ink penetration hole 5 in the rectangular area 43 are the same, so the overall projection is rectangular. Since the width of the connecting bridge 6 along the perpendicular direction of printing is greater than the width of the ink penetration channel 3 along the perpendicular direction of printing, the width of the ink penetration hole 5 at this position is also larger, which can ensure the ink permeability of the rectangular area 43 as much as possible.
[0036] In this embodiment, the length of the rectangular area 43 along the printing direction is greater than the lengths of the gradient area 42 and the overlapping area 41 along the printing direction. In this embodiment, the rectangular area 43 is made as long as possible, and a large number of connecting bridges 6 are ensured within the rectangular area 43, thereby improving the reinforcing performance of the rectangular area 43.
[0037] In this embodiment, the length of the connecting bridge 6 along the printing direction within the rectangular area 43 is between 11 micrometers and 16 micrometers. This length provides high strength for the connecting bridge 6, meeting production requirements.
[0038] In this embodiment, the length of the connecting bridge 6 in the gradient area 42 and the overlapping area 41 along the printing direction is between 6 micrometers and 12 micrometers. At this length, the connecting bridge 6 exhibits good ink flow, which meets production requirements.
[0039] Each reinforced zone 4 contains, in sequence, an overlap zone 41, a gradient zone 42, a rectangular zone 43, another gradient zone 42, and another overlap zone 41. Through multiple experiments, the following specific embodiments are provided, which have good strength and ink transfer properties.
[0040] Example 1: In this example, the lengths of the overlapping area 41, the gradient area 42, the rectangular area 43, the gradient area 42, and the overlapping area 41 along the printing direction are 9 micrometers, 11 micrometers, 14 micrometers, 11 micrometers, and 9 micrometers, respectively.
[0041] Example 2: In this example, the lengths of the overlapping area 41, the gradient area 42, the rectangular area 43, the gradient area 42, and the overlapping area 41 along the printing direction are 9 micrometers, 11 micrometers, 15 micrometers, 11 micrometers, and 9 micrometers, respectively.
[0042] Example 3: In this example, the lengths of the overlapping area 41, the gradient area 42, the rectangular area 43, the gradient area 42, and the overlapping area 41 along the printing direction are 9 micrometers, 12 micrometers, 14 micrometers, 12 micrometers, and 9 micrometers, respectively.
[0043] Example 4: In this example, the lengths of the overlapping area 41, the gradient area 42, the rectangular area 43, the gradient area 42, and the overlapping area 41 along the printing direction are 10 micrometers, 11 micrometers, 15 micrometers, 11 micrometers, and 10 micrometers, respectively.
[0044] Example 5: In this example, the lengths of the overlapping area 41, the gradient area 42, the rectangular area 43, the gradient area 42, and the overlapping area 41 along the printing direction are 9 micrometers, 12 micrometers, 16 micrometers, 12 micrometers, and 10 micrometers, respectively.
[0045] In some embodiments, the lengths of the connecting bridges 6 in the gradient area 42 and the overlapping area 41 along the printing direction are the same.
[0046] In some embodiments, the lengths of the connecting bridges 6 in the gradient area 42 and the overlapping area 41 along the printing direction are different. In some of these embodiments, the length of the connecting bridges 6 in the gradient area 42 along the printing direction is shorter than the length of the connecting bridges 6 in the overlapping area 41 along the printing direction, as long as ink flow is guaranteed.
[0047] The length of the connecting bridge 6 in the gradient area 42 and the overlapping area 41 along the printing direction needs to be comprehensively considered in terms of ink transfer and strength.
[0048] The printing equipment of this utility model includes a frame, an ink supply mechanism, a pad printing mechanism, and a gradient hybrid bridging fully open steel plate 100. The gradient hybrid bridging fully open steel plate 100 can balance strength and ink flow, giving the printing equipment better printing results and a longer service life.
[0049] The fully open steel plate 100 with gradient hybrid bridging and printing equipment of this utility model can balance ink flow and strength by setting different lengths of the connecting bridges 6 at different positions in the reinforcing zone 4, so as to meet the requirements of ink flow and not easily break.
[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
