Description
Technical Field
[0001] This utility model relates to the field of screen printing technology, and in particular to a screen printing stencil structure that reduces adhesive overflow. Background Technology
[0002] In existing screen printing technology, the core structure usually includes a screen frame and mesh fixed to the screen frame. However, in actual printing applications, there is a problem of limited production efficiency. Existing screen frames lack convenient splicing structures, making it impossible to quickly combine and disassemble multiple screen frames. The single-screen frame operation mode is difficult to meet the needs of high-efficiency production, which restricts the continuity and efficiency of screen printing processing.
[0003] Based on this, the present invention provides a screen printing stencil structure that reduces adhesive overflow to solve one or more of the problems mentioned above. Utility Model Content
[0004] This invention provides a screen printing stencil structure that reduces adhesive overflow, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution, including a wire frame and a mesh fixed on the wire frame. The mesh has a regular pattern on the contact area corresponding to the edge of the product to be printed, which is used to prevent glue from overflowing. The regular pattern is a multi-layered circular raised structure. A connecting unit is installed on the outer wall of the wire frame.
[0006] Preferably, the circular protrusion structure is configured with 3-4 layers, and the diameter of each layer of circular protrusion is 0.2-0.5mm, and the spacing between two adjacent layers of circular protrusion is 0.5-1.2mm.
[0007] Preferably, the regular pattern is used to replace the structure of the existing screen printing stencil mesh edge to enhance the barrier effect against glue flow.
[0008] Preferably, the regular pattern can be replaced with a concentric ring structure, wherein the ring width of the concentric ring is 0.5-1mm.
[0009] Preferably, the regular pattern can be replaced with a rectangular ring structure, wherein the ring width is 0.8-1mm.
[0010] Preferably, the connecting unit consists of a set of plug-in components and two sets of fasteners. The plug-in components are fixedly provided on one side of the mesh frame, and the two sets of fasteners are symmetrically fixed on the other side of the mesh frame.
[0011] Preferably, the connector has two sets of clearance grooves symmetrically opened at both ends, and each set of clearance grooves has a snap-fit groove.
[0012] Preferably, the two sets of fixing members have the same guide groove on the side that is close to each other, and the guide groove divides the end of the fixing member into an upper clamping plate and a lower clamping plate, and a snap-fit member is installed in the guide groove.
[0013] Preferably, the upper card plate is provided with a positioning groove and a rectangular groove three, and the positioning groove is located on the front side of the rectangular groove three; The lower card plate has a rectangular slot one and a rectangular slot two, and the rectangular slot one is located behind the rectangular slot two.
[0014] Preferably, the locking component comprises an anti-detachment plate one, a trapezoidal locking block, a rectangular post, and an anti-detachment plate two. The anti-detachment plate one is movably disposed within the positioning groove, and the anti-detachment plate two is fixedly disposed within the rectangular groove one. One end of the trapezoidal locking block is fixedly connected to the anti-detachment plate one, and the other end of the trapezoidal locking block is fixedly connected to the rectangular post. The trapezoidal locking block is slidably connected to the rectangular groove three, and the rectangular post is slidably connected to the rectangular groove two. A return spring is provided inside the rectangular post, and one end of the return spring is fixedly connected to the trapezoidal locking block, and the other end of the return spring is fixedly connected to the anti-detachment plate two.
[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: Through a multi-dimensional physical barrier structure consisting of 3-4 layers of circular protrusions, concentric rings, or rectangular rings, a stepped adhesive flow effect is formed. Compared with traditional single outward-expanding protrusions, the adhesive flow resistance is increased by more than 60%, and the overflow rate is reduced by 80%, effectively avoiding product appearance contamination and assembly precision issues, and ensuring screen printing quality. Simultaneously, the regular pattern can be flexibly adjusted according to product size (dense circular protrusions for small sizes, concentric rings for large sizes), structure (complex gradient structure for complex products), and precision requirements. Furthermore, relevant parameters (such as circular protrusion diameter 0.2-0.5mm, concentric ring width 0.5-1mm) can be set as needed, providing a wide range of adaptability. In addition, the mesh frame achieves "insertion self-locking and pull-out disassembly" through splicing units composed of connectors and fasteners, requiring no additional tools. Multiple mesh frames can be flexibly combined, ensuring no slippage after assembly and significantly improving production efficiency. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0020] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed by this utility model.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution, including a frame 1 and a mesh 2 fixed on the frame 1. The mesh 2 has a regular pattern on the contact area corresponding to the edge of the product to be printed, which is used to prevent glue from overflowing. The regular pattern is a multi-layered circular raised structure. A connecting unit is installed on the outer wall of the frame 1.
[0023] Furthermore, the circular protrusion structure is configured with 3-4 layers, and the diameter of each layer of circular protrusion is 0.2-0.5mm, and the spacing between two adjacent layers of circular protrusion is 0.5-1.2mm.
[0024] Furthermore, the regular pattern is used to replace the structure of the existing screen printing stencil mesh edge to enhance the barrier effect against glue flow.
[0025] Furthermore, the regular pattern can be replaced with a concentric ring 5 structure, wherein the ring width of the concentric ring 5 is 0.5-1mm.
[0026] Furthermore, the regular pattern can be replaced with a rectangular ring 6 structure, the width of which is 0.8-1mm.
[0027] The working principle and beneficial effects of the above solution are as follows: During printing, a multi-dimensional physical barrier is formed by a regular pattern of 3-4 layers of circular protrusions, concentric rings 5 or rectangular rings 6. Compared with a single outward protrusion, the glue flow resistance is increased by more than 60%, and the glue overflow rate can be reduced by 80%, effectively avoiding product appearance pollution and assembly problems. Regular patterns can be flexibly adjusted according to product size (dense circular protrusions for small sizes, concentric rings for large sizes) and structure (complex gradient structures for complex products) to meet the screen printing requirements of different precision. Therefore, during printing, the multi-layered circular protrusions form a stepped barrier, and the glue is diverted layer by layer as it flows along the edge of the mesh. The amount of glue naturally decreases at the edge of the product, and there is no glue overflow. It is suitable for small-sized products, and multiple mesh frames can be combined by setting the connecting unit, which improves production efficiency.
[0028] Example 2: Please refer to Figures 4-10The connecting unit consists of a set of plug-in parts 3 and two sets of fasteners 4. The plug-in parts 3 are fixedly provided on one side of the mesh frame 1, and the two sets of fasteners 4 are symmetrically fixed on the other side of the mesh frame 1.
[0029] Furthermore, the connector 3 has two sets of clearance grooves 7 symmetrically opened at both ends, and each set of clearance grooves 7 has a snap-fit groove 8.
[0030] Furthermore, the two sets of fixing members 4 are provided with the same guide groove 9 on the side that is close to each other, and the guide groove 9 divides the end of the fixing member 4 into an upper clamping plate 20 and a lower clamping plate 21. A snap-fit member 13 is installed in the guide groove 9.
[0031] Furthermore, the upper card plate 20 is provided with a positioning groove 12 and a rectangular groove 3 14, and the positioning groove 12 is located on the front side of the rectangular groove 3 14; The lower card plate 21 has a rectangular slot 10 and a rectangular slot 21, and the rectangular slot 10 is located behind the rectangular slot 21.
[0032] Furthermore, the latching component 13 is composed of an anti-detachment plate 15, a trapezoidal latching block 16, a rectangular post 17, and an anti-detachment plate 19. The anti-detachment plate 15 is movably disposed in the positioning groove 12, and the anti-detachment plate 19 is fixedly disposed in the rectangular groove 10. One end of the trapezoidal latching block 16 is fixedly connected to the anti-detachment plate 15, and the other end of the trapezoidal latching block 16 is fixedly connected to the rectangular post 17. The trapezoidal latching block 16 is slidably connected to the rectangular groove 14, and the rectangular post 17 is slidably connected to the rectangular groove 11. A return spring 18 is provided in the rectangular post 17, and one end of the return spring 18 is fixedly connected to the trapezoidal latching block 16, and the other end of the return spring 18 is fixedly connected to the anti-detachment plate 19.
[0033] The working principle and beneficial effects of the above scheme are as follows: When combining two sets of mesh frames 1, as long as the connector 3 of one set of mesh frames 1 is inserted into the guide groove 9 of the fixing member 4, the clearance groove 7 on the connector 3 will push the trapezoidal block 16 to move. At this time, the trapezoidal block 16 drives the rectangular column 17 to move along the rectangular groove 14, and the return spring 18 inside it will be stretched synchronously. Since the anti-slip plate 19 is fixed in the rectangular groove 10, and the area of the rectangular groove 10 is larger than the area of the rectangular groove 11, the rectangular column 17 can slide in the rectangular groove 11, which plays a guiding and anti-slip role until the clearance groove 7 continues to move and pushes the trapezoidal block 16 to move. When 16 is lifted to its limit, the connector 3 is fully inserted into the fixing part 4. At this time, since the area of the snap-fit groove 8 is larger than the cross-sectional area of the trapezoidal snap-fit block 16, the trapezoidal snap-fit block 16 falls back into the snap-fit groove 8. At the same time, the rectangular column 17 is reset under the action of the return spring 18, and the anti-detachment plate 15 is inserted into the rectangular groove 14, thus completing the combination of the two sets of mesh frames 1. With the cooperation of the rectangular groove 11 and the rectangular column 17, and the rectangular groove 14 and the anti-detachment plate 15, the connector 3 and the fixing part 4 are prevented from slipping and play a self-locking and limiting role. When disassembly is required, simply hold the anti-detachment plate 15 and pull up the trapezoidal snap-fit block 16, and then directly pull the connector 3 out of the fixing part 4.
[0034] By using the connecting unit, during assembly, the plug-in component can be inserted into the fixing component, and the trapezoidal locking block and return spring achieve self-locking and limiting, requiring no additional tools. Disassembly is simple and efficient; just grip the anti-slip plate and pull up the trapezoidal locking block to remove it. Multiple mesh frames can be combined using the splicing unit, solving the problem of low production efficiency for single mesh frames. Simultaneously, the self-locking structure (rectangular groove and locking component) prevents slippage after assembly, balancing assembly stability and production continuity. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
