[0002] The high-strength and low-elongation printing screen is a screen used in the semiconductor printing field, made of special synthetic fibers and metal materials, which can ensure the consistency of printing quality. The excellent material properties of high strength provide reliable guarantees for printing quality, production efficiency and product performance.

[0003] After retrieval, the Chinese patent publication number is: CN113320278B, which discloses a high-strength and low-elongation printing screen and its production process, including an installation frame and a fixing plate. Installation sliding rails are arranged on both sides inside the installation frame and one end of the back inside the installation frame. Overflow grooves are arranged on both sides of the top of the installation frame. Connecting grooves are arranged on the mutually remote sides inside the overflow grooves. Ink collecting cavities are arranged on both sides and one end of the back of the installation frame. Drainage pipes are arranged on the back ends of both sides of the ink collecting cavity. A printing plate is slidably sleeved inside the three groups of installation sliding rails. A printing screen is arranged at the middle position inside the printing plate. A metal film is arranged at the edge of the top of the printing screen. Slots are arranged on both sides of one end of the front of the installation frame. Through the mutual cooperation among the overflow groove, the connecting groove, the drainage pipe and the ink collecting cavity, when there is a lot of waste ink in the printing screen, the waste ink can be processed in time, making the printed pattern more beautiful and improving the printing quality. However, since the printing position of this printing screen cannot be adjusted horizontally and vertically during printing, it cannot provide good position adjustment ability during printing and cannot meet the actual use requirements. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a high-strength and low-elongation printing screen, aiming to improve the problem that the printing position of the printing screen in the prior art cannot be adjusted during printing.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A high-strength and low-elongation printing screen, including an operating table. The front, rear, left and right ends of the top wall of the operating table are fixedly connected with lifting worm gears and worm shafts. The middle part of the outer wall of the lifting worm gears and worm shafts is fixedly connected with a turning handle. The top of the lifting worm gears and worm shafts is fixedly connected with a fixing block. A horizontal groove is opened in the middle part of the outer wall of the fixing block. A screen sheet is slidably connected inside the horizontal groove. Positioning bolts are threadedly connected to the front and rear sides of the outer wall of the fixing block. The ends of the positioning bolts are rotatably connected with the screen sheet. An adjusting mechanism is installed at the bottom of the operating table, and the adjusting mechanism is used to adjust the position of the semiconductor component to be printed.

[0006] Through the above technical solution: When using the screen sheet for printing, first, the lifting worm and worm gear need to be driven by turning the handle to precisely adjust the vertical position of the screen sheet, ensuring that the screen sheet can be accurately adjusted to the ideal height. After the vertical position of the screen sheet is adjusted, turn multiple positioning bolts simultaneously. By turning the positioning bolts, the screen sheet can move forward or backward, effectively adjusting its horizontal position, ensuring that the screen sheet can be accurately adjusted to the ideal position, avoiding deviation in the printing effect caused by the inability to adjust the position of the screen sheet, ensuring the smooth progress of the entire printing process, and achieving higher production quality and efficiency.

[0007] As a further description of the above technical solution:

[0008] The adjusting mechanism includes a chute. The chute is opened in the middle of the top wall of the operating table. A rotating gear is rotatably connected to the front side inside the chute. The bottom of the rotating gear is fixedly connected with a knob. A driven gear is rotatably connected to the rear side inside the chute. The driven gear is meshed with the rotating gear. A bearing plate is arranged on the top of the chute. The front side of the bottom of the bearing plate is fixedly connected with a first rack. The first rack is meshed with the front side of the outer wall of the rotating gear. The rear side of the bottom of the bearing plate is fixedly connected with a second rack. The second rack is meshed with the rear side of the outer wall of the driven gear.

[0009] Through the above technical solution: When the screen sheet is adjusted to the ideal position, turn the knob. At this time, due to the precise control of the knob, the rotating gear will start to rotate. As the rotating gear rotates, the driven gear meshed with it will also rotate synchronously. Under the precise gear transmission, the bearing plate can be finely adjusted forward or backward, thereby driving the semiconductor to move accordingly. Through this fine adjustment, it can be ensured that the semiconductor is accurately positioned to an ideal position. After the position adjustment of the semiconductor is completed and confirmed to be correct, start using the adjusted screen sheet for precise printing work. The entire printing process can proceed smoothly, ensuring that the quality of the final product meets the expected standards.

[0010] As a further description of the above technical solution:

[0012] Through the above technical solution: Through the support columns, the stable support of the operating table is realized, ensuring that the operating table remains stable during use. The backing plate can effectively prevent the support columns from sliding on the ground, improving the overall performance and safety of the equipment.

[0013] As a further description of the above technical solution:

[0014] At the four corners of the outer wall of the operating table, anti-collision shells are threadedly connected, and bolts are threadedly connected to the outer walls of the anti-collision shells.

[0015] Through the above technical solution: By installing the anti-collision shells, the damage to the equipment or vehicle can be effectively reduced in case of collision. Using bolts for fixation facilitates quick disassembly and replacement when needed.

[0016] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] On the middle parts of the left and right sides of the top wall of the operating table, telescopic rods are fixedly connected, and the tops of the telescopic rods are fixedly connected to the middle part of the bottom wall of the fixed block.

[0021] Through the above technical solution: The operating table and the fixed block are connected through the telescopic rods to provide a stable working platform.

[0022] As a further description of the above technical solution:

[0023] A connecting groove is formed in the middle and lower parts of the outer wall of the horizontal groove, and a receiving plate is slidably connected inside the connecting groove.

[0024] Through the above technical solution: By precisely connecting the connecting groove with the receiving plate, the receiving plate can be effectively fixed in place.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present invention: a high-strength and low-elongation printing screen, including an operating table 1. At the front, rear, left, and right ends of the top wall of the operating table 1, lifting worm gears 3 are fixedly connected. In the middle of the outer wall of the lifting worm gears 3, a turning handle 4 is fixedly connected. At the top of the lifting worm gears 3, a fixing block 5 is fixedly connected. In the middle of the outer wall of the fixing block 5, a horizontal groove 6 is opened. Inside the horizontal groove 6, a screen sheet 7 is slidably connected. On the front and rear sides of the outer wall of the fixing block 5, positioning bolts 8 are threadedly connected. The ends of the positioning bolts 8 are rotatably connected to the screen sheet 7. At the bottom of the operating table 1, an adjusting mechanism 2 is installed. The adjusting mechanism 2 is used to adjust the position of the semiconductor component to be printed; at the four corners of the bottom of the operating table 1, support columns 9 are fixedly connected. At the bottom of the support columns 9, a backing plate 10 is fixedly connected.

[0040] Specifically, during the process of semiconductor printing, when using the screen sheet 7 for printing, first, the turning handle 4 needs to be rotated to drive the lifting worm gears 3 to rise or fall in this way, so as to achieve precise adjustment of the vertical position of the screen sheet 7. When the vertical position of the screen sheet 7 is adjusted to an ideal height, then multiple positioning bolts 8 need to be rotated simultaneously. By rotating these positioning bolts 8, the screen sheet 7 can move forward or backward, thereby effectively adjusting its horizontal position and avoiding deviation in the printing effect caused by the inability to adjust the position of the screen sheet 7. Through adjustment, the production efficiency can be significantly improved, and the smooth progress of the printing process can be ensured; the operating table 1 is supported through the support columns 9, and the backing plate 10 effectively prevents the support columns 9 from sliding, avoiding the problem of unstable equipment working state caused by the sliding of the support columns 9.

[0041] Referring to Figure 1 , Figure 3 and Figure 5, the adjusting mechanism 2 includes a sliding groove 201. The sliding groove 201 is opened in the middle of the top wall of the operating table 1. A rotating gear 202 is rotatably connected to the front side inside the sliding groove 201. A knob 203 is fixedly connected to the bottom of the rotating gear 202. A driven gear 204 is rotatably connected to the rear side inside the sliding groove 201. The driven gear 204 is meshed with the rotating gear 202. A bearing plate 205 is arranged at the top of the sliding groove 201. A first rack 206 is fixedly connected to the front side of the bottom of the bearing plate 205. The first rack 206 is meshed with the front side of the outer wall of the rotating gear 202. A second rack 207 is fixedly connected to the rear side of the bottom of the bearing plate 205. The second rack 207 is meshed with the rear side of the outer wall of the driven gear 204; Threaded collision-proof shells 11 are connected to the four corners of the outer wall of the operating table 1. Bolts 12 are threadedly connected to the outer walls of the collision-proof shells 11;

[0042] Specifically, when the wire mesh sheet 7 is adjusted to an ideal position, start to adjust the position of the semiconductor to be printed. Rotate the knob 203. At this time, due to the effect of the knob 203, the rotating gear 202 will start to rotate. As the rotating gear 202 rotates, the driven gear 204 will also rotate accordingly. Under the action of this rotation, the bearing plate 205 can be adjusted forward or backward, thereby driving the semiconductor to move correspondingly and adjusting the semiconductor to an ideal position. After the position adjustment of the semiconductor is completed, the wire mesh sheet 7 that has been adjusted in place can be used for printing work; The damage caused by collision is reduced through the collision-proof shell 11, and the collision-proof shell 11 is fixed by using the bolt 12, and at the same time, the replacement of the collision-proof shell 11 is realized.

[0043] Refer to Figure 1 and Figure 3 , a square groove 13 is opened on the top wall of the bearing plate 205. A plurality of particle protrusions 14 are fixedly connected to the bottom of the square groove 13 at equal intervals; A connecting groove 16 is opened in the middle and lower part of the outer wall of the horizontal groove 6. A receiving plate 17 is slidably connected inside the connecting groove 16;

[0044] Specifically, the semiconductor can be effectively clamped through the square groove 13, and at the same time, the particle protrusions 14 can effectively prevent it from sliding; The receiving plate 17 is fixed through the connecting groove 16, and the receiving plate 17 can prevent the excess printing dye from dripping and polluting the operating table 1 after printing.

[0045] Refer to Figure 1 and Figure 4 , telescopic rods 15 are fixedly connected to the middle parts of the left and right sides of the top wall of the operating table 1. The tops of the telescopic rods 15 are fixedly connected to the middle part of the bottom wall of the fixed block 5; A limiting strip 18 is fixedly connected to the rear side of the bottom wall of the operating table 1. A storage box 19 is slidably connected inside the limiting strip 18;

[0046] Specifically, the operating table 1 and the fixed block 5 can be connected through the telescopic rod 15; the sliding of the storage box 19 is realized through the limiting strip 18, and the storage box 19 effectively increases the storage space.

[0047] Working principle: When printing a semiconductor using the screen plate 7, rotate the turning handle 4 to raise or lower the lifting worm and worm gear 3, thereby realizing the adjustment of the vertical position of the screen plate 7; when the vertical position is adjusted to the ideal height, rotate multiple positioning bolts 8 simultaneously. At this time, the screen plate 7 moves forward or backward, thereby effectively adjusting the horizontal position of the screen plate 7, avoiding the deviation of the printing effect caused by the inability to adjust the position of the screen plate 7, and improving production efficiency.

[0048] When the screen plate 7 is adjusted to the ideal position, start adjusting the position of the semiconductor to be printed. Rotate the knob 203. At this time, the rotating gear 202 will start to rotate under the action of the knob 203, thereby driving the driven gear 204 to rotate. Since the rack one 206 and the rack two 207 are meshed with the rotating gear 202 and the driven gear 204, the carrier plate 205 can be adjusted forward or backward, thereby driving the semiconductor to move; after adjusting to the ideal position, start printing using the screen plate 7. The screen plate 7 is made of a special material, can withstand high strength, and at the same time has the characteristics of low elongation, which can effectively prevent the deformation of the screen plate 7 caused by long-term printing, and avoid the influence on the printing effect caused by the deformation of the screen plate 7.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
