Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of screen printing, in particular to a high-precision screen plate. BACKGROUND

[0002] With the in-depth application of screen printing in touch screens, lenses, solar cells, microelectronics, electronic components and other industries, the printed lines of the screen plate are becoming thinner and thinner, and the control requirements for the size deformation of printing are becoming higher and higher. In order to ensure the accuracy of printing, the height of the printing table, the position of the screen frame and the pressure angle of the squeegee need to be accurately adjusted.

[0003] In order to further ensure the accuracy of printing, some existing devices (for example: the authorized announcement number is CN207825701U, and the name is: an edge reinforced screen plate) include a screen frame and an inner yarn provided in the screen frame. The inner yarn is a screen yarn. A metal film is further provided between the screen frame and the screen yarn. The metal film is annularly covered on the periphery of the entire screen yarn body. The metal film is a solid metal sheet or a perforated metal sheet. The metal film is formed by electroplating process or metal sheet cutting. The metal film is made of stainless steel or nickel alloy. The thickness of the metal film is 10-500μm. As an optimization, the thickness of the metal film is 50-20μm. The contact surface between the metal film and the inner yarn is a roughened surface. The roughened surface is formed by sandblasting, laser dotting or high-mesh sandpaper polishing process. The screen yarn and the metal film are bonded by glue, hot melt adhesive or photosensitive adhesive. By fixing the metal film on the edge of the screen plate, the strength of the screen plate is improved, and the stretchability of the screen is reduced. However, if the screen yarn is slightly offset due to external reasons such as accidental impact, the screen printing accuracy is affected. At this time, the metal film and the screen yarn are bonded around the edge, the stretchability of the screen yarn cannot be adjusted well, and the screen yarn and the metal film need to be replaced, which increases the production cost. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a high-precision screen plate to solve the problem that the screen yarn fixing and screen yarn adjustment cannot be considered in the prior art.

[0005] According to the high-precision screen plate provided by the present application, the screen frame has a frame and a bottom plate. The frame is arranged along the circumferential edge of the bottom plate. The screen yarn is arranged above the bottom plate. The circumferential edge of the screen yarn is fixed to the bottom plate by screen bonding glue. The screen yarn has a graphic area. The adjustment structure includes an adjustment tape and a plurality of adjustment screws. The first end of the adjustment tape is bonded to the screen yarn. The bonding position is between the circumferential edge of the screen yarn and the graphic area. The second end of the adjustment tape is penetrated by the plurality of adjustment screws, and the adjustment tape is tightened by rotating the adjustment screws into the frame.

[0006] In some embodiments, the frame is a rectangular frame. The adjustment tape is provided with four groups. The four groups of adjustment tapes are arranged in one-to-one correspondence with the four sides of the frame. The four groups of adjustment tapes are sequentially arranged along the circumference of the screen yarn.

[0007] In some embodiments, a plurality of adjusting screws are spaced apart along the extension direction of the adjusting tape, with each set of adjusting tapes corresponding to 15 to 30 adjusting screws.

[0008] In some embodiments, the adjusting tape is divided into an adhesive section, a tensioning section, and a mating section. The adhesive section is attached to the mesh, the tensioning section is located between the adhesive section and the mating section, and the mating section is pierced by an adjusting screw.

[0009] In some embodiments, the tensioning section and the base plate are arranged at an angle between 15° and 65°.

[0010] In some embodiments, the pasting segment is located between the graphic area and the circumferential edge of the mesh.

[0011] In some embodiments, the adjustment structure further includes stainless steel springs, and four sets of stainless steel springs are provided, with the four sets of stainless steel springs corresponding one-to-one with the four sides of the frame.

[0012] In some embodiments, four sets of stainless steel springs are provided with a plurality of first threaded holes along the extension direction, and the side of the frame facing the mesh is provided with a plurality of second threaded holes along the extension direction. The plurality of first threaded holes, the plurality of second threaded holes and the plurality of adjusting screws are all provided in a corresponding manner.

[0013] In some embodiments, the wire frame is made of aluminum alloy.

[0014] In some embodiments, the base plate is provided with an opening, which corresponds to a graphic area.

[0015] The high-precision adjustable screen printing plate, applying the technical solution of this application, includes: a screen frame, a screen mesh, and an adjustment structure. The screen frame has a border and a base plate, with the border set along the circumferential edge of the base plate. The screen mesh is positioned above the base plate, and its circumferential edge is fixed to the base plate using adhesive. The screen mesh has graphic areas, through which ink is printed onto the product to be screen printed. The adjustment structure includes an adjustment tape and multiple adjustment screws. The first end of the adjustment tape is adhered to the screen mesh, positioned between the circumferential edge of the screen mesh and the graphic area. This arrangement ensures that minor adjustments to the screen mesh are not affected by the tape's fixation. Multiple adjustment screws pass through the second end of the adjustment tape and are screwed into the border to tighten the tape. Adjusting the degree of screwing in allows for adjustment of the tape's tension, thereby enabling minor adjustments to the screen mesh, resulting in better screen printing accuracy and greater adaptability to the product being screen printed. The technical solution of this application effectively solves the problem of simultaneously achieving screen mesh fixation and adjustment in existing technologies. Attached Figure Description

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] like Figure 1 and Figure 2 As shown, the embodiment relates to a high-precision adjustable screen, including: a screen frame 10, a mesh 20, and an adjustment structure 30. The screen frame 10 has a frame 11 and a base plate 12, with the frame 11 arranged along the circumferential edge of the base plate 12. The mesh 20 is disposed above the base plate 12, and the circumferential edge of the mesh 20 is fixed to the base plate 12 by adhesive. The mesh 20 has a graphic area 21. The adjustment structure 30 includes an adjustment tape 31 and multiple adjustment screws 32. The first end of the adjustment tape 31 is adhered to the mesh 20, with the adhesion position between the circumferential edge of the mesh 20 and the graphic area 21. The multiple adjustment screws 32 all pass through the second end of the adjustment tape 31 and are screwed into the frame 11 to tighten the adjustment tape 31.

[0028] The high-precision adjustable screen printing plate, using the technical solution of this embodiment, includes: a screen frame 10, a screen mesh 20, and an adjustment structure 30. The screen frame 10 has a border 11 and a base plate 12, with the border 11 arranged along the circumferential edge of the base plate 12. The screen mesh 20 is positioned above the base plate 12, and its circumferential edge is fixed to the base plate 12 using adhesive. The screen mesh 20 has graphic areas 21, through which ink is printed onto the product to be screen printed. The adjustment structure 30 includes an adjustment tape 31 and multiple adjustment screws 32. The first end of the adjustment tape 31 is adhered to the screen mesh 20, with the adhesion position between the circumferential edge of the screen mesh 20 and the graphic area 21. This arrangement ensures that when the adjustment tape 31 is pulled to make minor adjustments to the screen mesh 20, the fixing effect of the screen mesh 20 is not affected. Multiple adjusting screws 32 pass through the second end of the adjusting tape 31 and are screwed into the frame to tighten the tape 31. Adjusting the degree to which the adjusting screws 32 are screwed in allows for adjustment of the tension of the tape 31, thereby enabling minor adjustments to the mesh 20, resulting in better screen printing accuracy and greater adaptability to screen-printed products. The technical solution of this embodiment effectively solves the problem in the prior art where it is difficult to simultaneously achieve mesh fixing and mesh adjustment.

[0029] It should be noted that by adjusting the degree of screwing in the adjusting screw 32, the adjusting tape 31 can be pulled, which in turn causes a slight deformation of the mesh 20, achieving fine-tuning of the graphic area 21. This makes the correspondence between the graphic area 21 and the product to be screen-printed more precise, improving screen-printing accuracy. Furthermore, because the adjustment of the mesh 20 is minor, the screwing range of the adjusting screw 32 will not be too large, and the tension of the adjusting tape 31 will remain within its elastic deformation range.

[0030] It should also be noted that the adjusting tape 31 is made of Silver Dragon tape.

[0031] like Figure 1 As shown, in some embodiments, the frame 11 is a rectangular frame, and four sets of adjustment tape 31 are provided. The four sets of adjustment tape 31 are arranged one-to-one with the four sides of the frame 11, and the four sets of adjustment tape 31 are arranged sequentially along the circumference of the mesh 20. The mesh 20 is a rectangular mesh, and the four sets of adjustment tape 31 are arranged sequentially along the four sides of the mesh 20. In the actual pasting process, adjacent adjustment tapes 31 may partially overlap. Or, to avoid the adjustment tapes 31 overlapping and affecting the adjustment quality, an appropriate length of adjustment tape 31 can be selected. The length of the adjustment tape 31 should be sufficient to cover the size of the corresponding graphic area 21.

[0032] like Figure 1 As shown, in some embodiments, multiple adjusting screws 32 are spaced apart along the extension direction of the adjusting tape 31, and the number of adjusting screws 32 corresponding to each set of adjusting tape 31 is 15 to 30. The degree of screwing in each adjusting screw 32 can be adjusted individually, which makes the correspondence between the adjusting screw 32 and the graphic area 21 more precise. Tightening the adjusting screw 32 individually can achieve precise adjustment of the minute position of the graphic area 21.

[0033] like Figure 2 As shown, in some embodiments, the adjusting tape 31 is divided into an adhesive section 311, a tensioning section 312, and a mating section 313. The adhesive section 311 is adhered to the mesh 20, so pulling the adhesive section 311 can pull the mesh 20. The tensioning section 312 is located between the adhesive section 311 and the mating section 313. The tensioning section 312 is in a tensioned state. Pulling the side of the tensioning section 312 away from the adhesive section 311 can achieve the purpose of pulling the adhesive section 311, thereby achieving the adjustment of the mesh 20. The mating section 313 is passed through by the adjusting screw 32. By tightening the adjusting screw 32, the tension of the mating section 313 can be adjusted.

[0034] like Figure 2As shown, in some embodiments, the tensioning section 312 and the base plate 12 are arranged at an inclined angle. This inclined angle facilitates adjustment of the tension of the adjusting tape 31. The inclined angle is between 15° and 65°. If the inclined angle is too small, the adjusting tape 31 may easily stick to the base plate 12, affecting subsequent adjustments. If the inclined angle is too large, gaps may easily form at the adhesion point between the adjusting tape 31 and the mesh 20 when the adjusting screw 32 is tightened. With increased tightening, the adjusting tape 31 and the mesh 20 may even detach. In this embodiment, the inclined angle is 30°, which allows for effective adjustment of the mesh 20 without affecting the adhesion between the adjusting tape 31 and the mesh 20.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the edge of the mesh 20 is fixed together with the base plate 12 by adhesive. The adhesive segment 311 is located between the graphic area 21 and the circumferential edge of the mesh 20. When the mesh 20 is pulled, the adhesive segment 311 is not affected by the adhesive on the circumferential edge of the mesh 20. Therefore, it is possible to adjust the mesh 20 without affecting its fixation.

[0036] like Figure 2 and Figure 4 As shown, in some embodiments, the adjustment structure 30 further includes stainless steel springs 33, of which four sets are provided, and the four sets of stainless steel springs 33 are correspondingly arranged on the four sides of the frame 11. The introduction of stainless steel springs 33 can enhance the installation strength of the frame 11. If only the adjustment screws 32 are screwed into the frame 11, the strength of the frame 11 will be affected with frequent turning of the adjustment screws 32, which may easily affect the screen printing accuracy.

[0037] like Figure 3 and Figure 4 As shown, in some embodiments, four sets of stainless steel springs 33 have multiple first threaded holes along their extension direction, and the side of the frame 11 facing the mesh 20 has multiple second threaded holes along its extension direction. The multiple first threaded holes, multiple second threaded holes, and multiple adjusting screws 32 are all correspondingly arranged. The adjusting screws 32 are screwed into the first threaded holes and the second threaded holes in sequence. After all the adjusting screws 32 are installed, the position of the stainless steel springs 33 is fixed.

[0038] In some embodiments, the frame 10 is made of aluminum alloy. Using aluminum alloy can significantly reduce the overall weight of the high-precision adjustment screen, making it easier to handle and install. At the same time, the tensile strength is above 300MPa, which can meet the structural stability requirements of high-precision printing.

[0039] In some embodiments, the base plate 12 is provided with an opening that corresponds to the graphic area 21 to ensure ink passage. The type of opening can be selected according to the application scenario, such as a full opening or a stepped opening.
