Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of screen, especially to a cross vice grid screen. BACKGROUND

[0002] The pattern on the traditional printing screen is generally arranged in a grid shape, that is, a plurality of long slot gaps arranged in an equal interval array are provided on the screen, but as the thickness of the screen becomes thinner, if the pattern on the screen is still arranged in a grid shape, the plate material on both sides of the slot gap on the screen obtained after processing will be deformed, thereby causing the grid line printed on the silicon wafer to be thick.

[0003] Chinese patent application No. 202223007389.1 discloses a screen printing steel sheet, a vice grid line printing screen, and a production equipment for battery pieces. The screen printing steel sheet is provided with a plurality of grid line printing areas arranged in a first direction. All the grid line printing areas are provided with a plurality of first slot gaps arranged uniformly in a second direction perpendicular to the first direction. The first slot gaps of adjacent two grid line printing areas are arranged in a staggered manner in the second direction. The utility model can reduce the risk of breaking of the screen printing steel sheet due to stress, and can also ensure that complete conductive grid lines are printed on the silicon wafer. The production equipment for battery pieces in the utility model prints vice grid lines and main grid lines on the silicon wafer through a vice grid line printing template. The screen printing steel sheet is not easy to break during the printing process, and complete conductive grid lines can be printed on the silicon wafer.

[0004] The above-mentioned vice grid line adopts a staggered arrangement design, which can solve the problem of breaking of the grid line due to stress to some extent. However, the width of the main grid line in the prior art is generally small. When the above-mentioned vice grid line is overlapped with the main grid line, slight misalignment will cause poor overlap. At the same time, when the above-mentioned vice grid line is stretched, the grid lines on both sides of the screen are arranged in a staggered manner, which can cause the problem of edge folding due to uneven tension. UTILITY MODEL CONTENTS

[0005] The utility model solves the technical problem of the prior art, and provides a cross vice grid screen. The cross vice grid screen can not only solve the problem of breaking of the grid line due to stress, but also has good overlap with the main grid line, and can effectively solve the problem of uneven tension caused by the difference between the grid lines on both sides.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] The application discloses a cross vice grid plate, which comprises a nickel alloy plate, a first grid line group, a second grid line group and a flush grid line segment.

[0008] Preferably, the number of the first grid line segments and the second grid line segments is equal.

[0009] Preferably, the intersection of the first grid line segments and the second grid line segments is subjected to a gradual widening treatment.

[0010] Preferably, the intersection width of the first grid line segments and the second grid line segments is 10-30 mu m.

[0011] Compared with the prior art, the application has the following beneficial effects:

[0012] The application adopts the arrangement method that the first grid line segments and the second grid line segments are cross and dislocated, increases the stress area between the adjacent first grid line segments and the second grid line segments, and further reduces the risk of fracture of the area due to stress; meanwhile, the cross first grid line segments and the second grid line segments are more easily connected with the main grid line, even if the position of the main grid line is deviated, the deviation can be compensated by the intersection of the first grid line segments and the second grid line segments, and the poor connection condition is avoided; meanwhile, due to the cross and dislocation arrangement of the first grid line segments and the second grid line segments, the upper and lower edges are deviated, in order to avoid the uneven stress of the upper and lower edges during the tensioning, the application also adopts the flush grid line segment, and the upper and lower edges are not deviated through the flush grid line segment.

[0019] Some embodiments of the present application will be described in detail below with reference to the drawings. The features in the following embodiments can be combined with each other without conflict.

[0020] Embodiment one:

[0021] As Figure 1As shown, a cross-type subgrid plate includes: a nickel alloy grid plate 10, and grid line group 20, grid line group 30, and flush grid line segment 40 formed on the nickel alloy grid plate 10; the grid line group 20 and the grid line group 30 are arranged at intervals; the grid line group 20 is formed by a plurality of grid line segments 21 evenly arranged; the grid line group 30 is formed by a plurality of grid line segments 31 evenly arranged; the grid line segments 21 and the grid line segments 31 are arranged in a staggered manner; the flush grid line segment 40 is used to fill the drop difference at both ends of the grid line group 20 and the grid line group 30.

[0022] The cross sub-grid screen is formed by multiple grid line groups 20 and multiple grid line groups 30 spaced apart on the nickel alloy screen 10. The number of grid line groups 20 and grid line groups 30 is determined according to actual needs.

[0023] The first grid line group 20 is composed of multiple grid line segments 21 arranged uniformly; the second grid line group 30 is composed of multiple grid line segments 31 arranged uniformly.

[0024] The number of gate segment 21 is equal to the number of gate segment 31.

[0025] The grid line segment 21 and grid line segment 31 are arranged in a staggered manner. This arrangement can effectively increase the stress area between adjacent grid line segments 21 and 31, thereby reducing the risk of breakage due to stress in this area. At the same time, the staggered arrangement can increase the overlap area with the main grid line. Even if there is a slight deviation during the printing of the main grid line, it will not affect the overlap effect between the main grid line and the sub-grid line.

[0026] The grid line segments 21 and 31 are arranged in a staggered manner, resulting in a height difference on both sides. To avoid uneven stress on the upper and lower sides during mesh stretching, which could cause the grid line segments 21 and 31 to flip up, a flush grid line segment 40 is added to the nickel alloy mesh 10. The flush grid line segment 40 is used to fill the height difference at both ends of the grid line group 20 and the grid line group 30, so that there is no height difference on the upper and lower sides of the sub-grid line, thus ensuring that the sub-grid line is subjected to uniform stress on both sides during mesh stretching.

[0027] like Figure 2 As shown, the intersection of gate segment 21 and gate segment 31 is gradually widened; the intersection width of gate segment 21 and gate segment 31 is 10-30μm.

[0028] In order to avoid stress concentration and ensure good lap joint with the main grid line, the embodiment further makes gradual widening treatment at the intersection part of the grid line segment one 21 and the grid line segment two 31, the widened auxiliary grid line is easier to lap joint with the main grid line, and the end of the grid line segment one 21 and the grid line segment two 31 is gradually widened, so that the stress concentration caused by sudden widening is prevented, thereby preventing the fracture caused by stress concentration during printing.

[0029] The basic principle and main features of the present application and the advantages of the present application are shown and described above, and it is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
