Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a screen printing device for patterns on the surface of a black crystal plate. Background Technology

[0002] With the continuous development of technology and people's increasing demand for high-quality and personalized products, black crystal board, as a material with excellent performance and beautiful appearance, has been widely used in electronic equipment, home decoration, automotive interiors and other fields. In electronic equipment, such as LCD screens and touch screens, the surface of black crystal board needs to be printed with precise patterns and markings to achieve functional indication and aesthetic effect.

[0003] However, in the existing technology, traditional equipment only has one set of work plates, which means that different colors of pigment can only be used on one set of work plates. This leads to the pigments mixing, resulting in the screen-printed color not matching the template color, thus affecting production. In addition, the pattern plates of traditional equipment are usually fixed, so changing the pattern template requires a lot of time from the staff, which in turn affects production efficiency.

[0006] Preferably, the outer wall of the locking block is engaged with the outer wall of the working plate, a sliding ball is slidably connected to the top of the fixing ring, and the sliding ball is arranged in a ring along the central axis of the fixing ring. The outer wall of the sliding ball is slidably connected to the bottom of the fixing plate, and two sets of fixing rings are provided.

[0007] Preferably, the screen printing mechanism includes a positioning frame with a through groove. A slide cylinder is fixedly connected to the outer wall of the positioning frame, a sliding frame is slidably connected to the inner wall of the slide cylinder, a magnetic block is fixedly connected to the outer wall of the sliding frame, a scraper is slidably connected to the inner wall of the positioning frame, and a pattern plate is slidably connected to the inner wall of the positioning frame.

[0008] Preferably, the top of the pattern plate is slidably connected to the bottom of the scraper, a permanent magnet is fixedly connected to the top of the scraper, and the permanent magnet is linearly arrayed along the outer wall of the scraper.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model, by setting a rotating mechanism, has five sets of working plates on the base, so that each set of working plates can correspond to different colors of pigment, thereby preventing the mixing of pigments from causing color differences in the screen-printed pattern. In addition, by using a locking block to restrict the working plates, the position of the working plates can be quickly locked, thereby achieving the purpose of reducing color differences and solving the problem that traditional equipment cannot reduce color differences.

[0011] 2. This utility model, by setting up a screen printing mechanism, utilizes the attraction between a magnetic block and a permanent magnet to quickly install the squeegee. The pattern plate in the screen printing can be directly slid into the positioning frame, and then the position of the pattern plate can be locked by sliding the positioning plate downwards. This achieves the purpose of quickly replacing the squeegee and the pattern plate, solving the problem that the pattern plate of traditional equipment cannot be quickly replaced.

[0020] Example:

[0021] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a screen printing device for patterns on the surface of a black crystal plate, comprising: a base 1; a rotating mechanism 2, the bottom of which is rotatably connected to the top of the base 1 via a fixed cylinder 6, and the bottom of the fixed cylinder 6 is fixedly connected to the top of the base 1; a screen printing mechanism 3, the bottom of which is rotatably connected to the top of the rotating mechanism 2; and a fixing ring 4, the bottom of which is fixedly connected to the top of the base 1; the rotating mechanism 2 includes a ring body 21, the outer wall of which is fixedly connected to a fixing plate 26, and the fixing plates 26 are arranged in a ring array along the central axis of the ring body 21. A working plate 22 is slidably connected to the outer wall of plate 26. An annular groove is provided in the wall of the working plate 22. A limiting plate 23 is fixedly connected to the outer wall of the working plate 22. An insert 24 is slidably connected to the inner wall of the limiting plate 23. Handles 25 are fixedly connected to the outer walls on both sides of the working plate 22. The bottom of the ring body 21 is rotatably connected to the top of the fixed cylinder 6. The outer wall of the insert 24 is slidably connected to the inner wall of the base 1 through a slot 7, and the slot 7 is provided in the wall of the base 1. A locking block 27 is fixedly connected to the outer wall of the fixed plate 26. The locking block 27 is locked to the outer wall of the working plate 22, thereby restricting the position of the working plate 22.

[0022] The outer wall of the locking block 27 is engaged with the outer wall of the working plate 22. The top of the fixing ring 4 is slidably connected to a slider 5, and the slider 5 is arranged in a ring along the central axis of the fixing ring 4. The outer wall of the slider 5 is slidably connected to the bottom of the fixing plate 26. The slider 5 rotates in the fixing ring 4, thereby reducing the friction between the fixing ring 4 and the rotating mechanism 2. The screen printing mechanism 3 includes a positioning frame 38. The outer wall of the positioning frame 38 is fixedly connected to a slide cylinder 32. The inner wall of the slide cylinder 32 is slidably connected to a sliding frame 31. The outer wall of the sliding frame 31 is fixedly connected to a magnetic block 33. The inner wall of the positioning frame 38 is slidably connected to a scraper 35. The inner wall of the positioning frame 38 is slidably connected to a pattern plate 37.

[0023] The top of the pattern plate 37 is slidably connected to the bottom of the scraper 35. The permanent magnet 34 is attracted by the magnetic block 33, thereby limiting the position of the scraper 35. The top of the scraper 35 is fixedly connected to the permanent magnet 34, and the permanent magnet 34 is linearly arrayed along the outer wall of the scraper 35. The inner wall of the positioning frame 38 is slidably connected to the positioning plate 36. The outer wall of the positioning plate 36 is in contact with the outer wall of the pattern plate 37. The bottom of the slide cylinder 32 is rotatably connected to the inner wall of the top of the ring 21.

[0024] Working principle:

[0025] In use, first place the base 1 on the ground. After the base 1 is stable, place the black crystal plate on the top of the rotating mechanism 2. The rotating mechanism 2 has five sets of working plates 22, and each set of working plates 22 corresponds to a color. Therefore, during the screen printing process on the black crystal plate, the rotating mechanism 2 needs to be rotated according to different colors to prevent the colors from mixing during the screen printing process on the black crystal plate, which would cause color difference in the pattern. Then, the ink can be printed on the black crystal plate by reciprocating the squeegee 35 in the screen printing mechanism 3. There are two sets of fixing rings 4 on the top of the base 1, and a slider 5 is provided on the top of the fixing rings 4 to reduce the friction between the rotating mechanism 2 and the fixing rings 4.

[0026] Before using the screen printing mechanism 3, the required pattern plate 37 needs to be installed in the positioning frame 38 on the slide cylinder 32. Simply slide the positioning plate 36 on the positioning frame 38 upward to release the lock on the pattern plate 37 in the positioning frame 38. Then, take out the pattern plate 37 from the positioning frame 38 and slide the required pattern plate 37 into the positioning frame 38. Then, slide the positioning plate 36 downward to relock the position of the pattern plate 37. A permanent magnet 34 is provided on the top of the squeegee 35. So, simply bring the top of the squeegee 35 close to the magnetic block 33 on the slide frame 31. The squeegee 35 is fixed on the slide frame 31 by the attraction between the magnetic block 33 and the permanent magnet 34. When replacing the squeegee 35, simply slide the squeegee 35 downward to separate the permanent magnet 34 from the magnetic block 33. Then, the squeegee 35 can be moved, thus printing the ink onto the black crystal plate through the pattern plate 37.

[0027] During the screen printing process, the black crystal plate can be placed on different work plates 22 according to different pigments. Simply slide the insert 24 away from the limiting plate 23 and let the insert 24 slide out of the slot 7 in the base 1. Then move the black crystal plate to the corresponding color work plate 22. Then grasp the handle 25 to drive the fixing plate 26 to rotate along the ring 21. The ring 21 is connected to the base 1 through the fixing cylinder 6 to support the position of the ring 21. The fixing plate 26 can be rotated to the bottom of the positioning frame 38. Then the insert 24 is moved along the limiting plate. The groove in 23 slides back into the slot 7, thus relocking the position of the work plate 22. When the work plate 22 is contaminated by other colors of pigment, simply pull out the insert 24, and then pinch the two sets of locking blocks 27 on the fixing plate 26 toward the limiting plate 23, so that the locking blocks 27 release the locking of the work plate 22. Then slide the work plate 22 away from the fixing plate 26 to replace the work plate 22. Then slide the new work plate 22 to the top of the fixing plate 26, and let the locking blocks 27 pass through the work plate 22, thereby relocking the work plate 22.
