Description

Technical Field

[0001] This utility model relates to the field of optical coated glass processing technology, and in particular to a fully automatic precision screen printing line for optical coated glass. Background Technology

[0002] Optical coated glass is an optical material in which a thin film of metal, alloy or metal compound is deposited on the glass surface by physical or chemical methods. Precision screen printing is required during the processing of optical coated glass. Optical coated glass, such as camera filters, augmented reality (AR) / virtual reality (VR) optical lenses, fingerprint covers, etc., usually needs to have light-shielding ink (black matrix), logos or functional patterns printed on its surface by screen printing process. Such products have high precision and high cleanliness requirements. The printed pattern must maintain a very high positional accuracy with the coated functional area (usually requiring a alignment error within ±10 micrometers), and the printed surface must not have any scratches, contamination or uneven ink layer defects.

[0003] Existing fully automated precision screen printing lines for optical coated glass do not have positioning components to effectively position and fix the optical coated glass during use. The lack of effective positioning of the optical coated glass during the screen printing process will seriously reduce the processing accuracy and make it easy for it to shift during the screen printing process, resulting in defects in the screen printing and seriously affecting the quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic precision screen printing line for optical coated glass.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully automatic precision screen printing line for optical coated glass includes a screen printing assembly. The screen printing assembly includes a base with a mounting groove on the top.

A connecting plate is provided at the top of the first rotary shaft. A fixing seat is provided at the top of the connecting plate. A second rotary motor is provided on one side of the fixing seat. The output end of the second rotary motor is connected to a second rotary shaft. One end of the second rotary shaft is rotatably inserted through the fixing seat. An adjustment frame is provided on the second rotary shaft. A placement platform is provided on the top of the adjustment frame. Several sets of fixing grooves are arranged sequentially on the placement platform. Positioning suction cups are provided through the fixing grooves.

A conveying assembly for conveying and an auxiliary assembly for preventing slippage are provided on one side of the base. The screen printing machine body is provided on the top of the base.

[0007] As a further embodiment of this utility model: the conveying assembly includes a fixed plate, which is installed on the top of the base. A motor compartment is provided on one side of the fixed plate. Several sets of output shafts are connected to the output end on one side of the motor compartment. One end of the output shaft can rotatably pass through the fixed plate, and a conveying roller is provided on the output shaft.

[0008] As a further embodiment of this utility model: the auxiliary component includes a support frame, which is installed on the top of the base. A hydraulic cylinder is provided on the top of the support frame. The telescopic end of the bottom of the hydraulic cylinder can slide through the support frame.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] A fully automated precision screen printing line for optical coated glass, such as Figure 1-4 As shown, the device includes a screen printing assembly, which includes a base 1. The top of the base 1 has a mounting groove through which a first rotary motor 21 is embedded. The output end of the top of the first rotary motor 21 is connected to a first rotary shaft 26. The top of the first rotary shaft 26 has a connecting plate 28. The top of the connecting plate 28 has a fixing seat 20. A second rotary motor 25 is provided on one side of the fixing seat 20. The output end of one side of the second rotary motor 25 is connected to a second rotary shaft 27. One end of the second rotary shaft 27 is rotatably inserted through the fixing seat 20. An adjustment frame 24 is provided on the second rotary shaft 27. The top of the adjustment frame 24 has a placement platform 3. The placement platform 3 has several sets of fixing grooves arranged in sequence. Positioning suction cups 4 are provided through the fixing grooves. A vacuum pump 22 is provided at the bottom of the placement platform 3. The several sets of positioning suction cups 4 are respectively connected to the vacuum pump 22. A conveying assembly for conveying and an auxiliary assembly for preventing slippage are provided on one side of the base 1. The top of the base 1 has a screen printing machine body 8.

[0026] In use, the optically coated glass can be conveyed via the conveying assembly to the placement table 3 for precise screen printing. The screen printing machine body 8 can use any existing mature product on the market; no innovative work has been done on it, therefore its structure and principle will not be elaborated upon further. The screen printing machine body 8 can install the required printing plate according to the screen printing pattern. After installation, ink can be added. By controlling the printing plate of the screen printing machine body 8 to fall, it can contact the optically coated glass on the placement table 3 for screen printing. The cylinder of the screen printing machine body 8 controls the reciprocating movement of the scraper to evenly spread the ink. After the optically coated glass is conveyed to the placement table 3, the bottom of the optically coated glass can contact the positioning suction cup 4. The vacuum pump 22 is started to remove air from the positioning suction cup 4. Removing air from the positioning suction cup 4 allows for the production of... The optically coated glass is adsorbed and positioned by suction force. It can be firmly fixed by vacuum adsorption, which facilitates precise screen printing. This effectively increases the accuracy of screen printing and avoids unnecessary displacement of the optically coated glass during screen printing, thus preventing defects. The rotation of the placement stage 3 can be controlled by starting the first rotary motor 21 and controlling the rotation of the first rotary shaft 26. The direction of the optically coated glass can be adjusted as needed. The rotation of the second rotary motor 25 can control the rotation of the second rotary shaft 27 and the adjustment frame 24. The angle between the placement stage 3 and the optically coated glass can be adjusted by rotating the adjustment frame 24. By adjusting the direction and angle, the optically coated glass can be adjusted to adapt to tilting or offset when it is transported to the placement stage 3, thereby increasing the accuracy of screen printing and further avoiding defects that affect the quality of screen printing.

[0027] The conveying assembly includes a fixed plate 15, which is installed on the top of the base 1. A motor compartment 14 is provided on one side of the fixed plate 15. Several sets of output shafts 16 are connected to the output end of one side of the motor compartment 14. One end of the output shaft 16 is rotatably installed through the fixed plate 15. A conveying roller 13 is provided on the output shaft 16.

[0028] In use, the optical coated glass can be conveyed onto the conveyor roller 13. The output shaft 16 and the conveyor roller 13 can be rotated through the motor compartment 14. The optical coated glass can be conveyed by the rotation of the conveyor roller 13 and then conveyed onto the placement table 3 for screen printing. The conveyor roller 13 is a dust-removing roller with a certain degree of stickiness, which can remove dust from the optical coated glass during conveying and prevent slippage during conveying.

[0029] The auxiliary component includes a support frame 10, which is mounted on the top of the base 1. A hydraulic cylinder 11 is provided on the top of the support frame 10. The telescopic end of the bottom of the hydraulic cylinder 11 can slide through the support frame 10. A connecting seat 12 is provided at the bottom of the hydraulic cylinder 11. A drive motor 17 is provided on one side of the connecting seat 12. An output end of the drive motor 17 is connected to a mounting shaft 18. One end of the mounting shaft 18 can rotatably pass through the connecting seat 12. A pressure roller 29 is provided on the mounting shaft 18. A cleaning component for cleaning impurities is provided on one side of the connecting seat 12.

[0030] In use, the drive motor 17 can be started to control the rotation of the mounting shaft 18 and the pressure roller 29. The hydraulic cylinder 11 can be started to control the pressure roller 29 to fall and contact the optical coated glass on the conveying roller 13, so as to press the optical coated glass. The pressing can assist the conveying of the optical coated glass and prevent slippage during conveying, which would affect the normal conveying. The rotating pressure roller 29 can avoid affecting the normal conveying of the optical coated glass.

[0031] The cleaning assembly includes two sets of cleaning brushes 9. Fixing rods are symmetrically installed on both sides of the connecting seat 12, and the two sets of cleaning brushes 9 are symmetrically installed on the two sets of fixing rods.

[0032] When in use, the hydraulic cylinder 11 controls the pressure roller 29 to fall, and the cleaning brush 9 falls synchronously. The cleaning brush 9 can come into contact with the optical coated glass during the conveying process. The cleaning brush 9 can effectively clean the optical coated glass by adhering to the conveyed glass, and can effectively remove the contaminants and impurities attached to its surface, so as to avoid the impurities and contaminants remaining and affecting the screen printing effect.

[0033] To assist with material feeding, such as Figure 1 , 3As shown in Figure 4, fixed supports 2 are symmetrically arranged on both sides of the placement platform 3. A first rotating shaft 26 is arranged on one side of the fixed support 2. A connecting shaft 19 is connected to the output end of the first rotating shaft 26. One end of the connecting shaft 19 can rotatably pass through the fixed support 2. An auxiliary roller 23 is arranged on the connecting shaft 19.

[0034] In use, the first rotating shaft 26 can start and control the rotation of the connecting shaft 19 and the auxiliary roller 23. After the screen printing is completed, the vacuum adsorption of the positioning suction cup 4 on the optical coated glass can be released, thereby releasing its positioning fixation. After the fixation is released, the auxiliary roller 23 can be controlled to rotate. The rotation of the auxiliary roller 23 can assist in the conveying of the optical coated glass, thereby facilitating its unloading. It can provide effective assistance. A conveying device can be connected to one side of the base 1. The position of the conveying device is adapted to the placement table 3. With the assistance of the auxiliary roller 23, the screen-printed optical coated glass can be conveyed to the conveying device for transfer, thereby facilitating its further processing.

[0035] In order to dry, such as Figure 1 , 3 As shown in Figure 4, a mounting plate 6 is provided on one side of the base 1, and a hot air blower 7 is provided on one side of the mounting plate 6. An air outlet and an air inlet are respectively connected to both sides of the hot air blower 7.

[0036] In use, the air outlet on one side of the hot air blower 7 is set through the mounting plate 6. When the optical coated glass is transported after screen printing is completed, hot air can be blown out through the air outlet by the hot air blower 7. By blowing out an appropriate amount of hot air, the optical coated glass after screen printing can be dried. The appropriate air volume can avoid blowing away the ink and causing defects. Drying can perform preliminary drying of the screen printing, which facilitates transportation and avoids defects in the screen printing during transportation.

Two sets of filter screens 5 are provided, and another set of filter screens 5 is detachably installed at the air inlet of the hot air blower 7.

[0039] When in use, the filter screen 5 can effectively protect the hot air blower 7, preventing foreign objects from entering through its air inlet and outlet and causing blockages that would affect normal use.
