[0002] A screen printing machine is a machine that uses a screen printing plate to apply printing. It belongs to the category of printing machines and is used to print text and images. It is a general term for machines or equipment used to produce printed materials. There are many types of screen printing machines, and their applications are very wide. They are also used in the photovoltaic glass production field. Although the existing screen printing machines have relatively perfect structures, they still have certain defects. The existing screen printing machines have complex structures, large size, and high equipment production costs. At the same time, a lot of manual labor is required in the production process, the automation level of the equipment is low, which reduces work efficiency and increases labor costs. In addition, after the printing is completed, the screen frame cannot be removed, making it difficult for workers to inspect the printing effect, which reduces the practicality of the equipment.

The machine includes a feeding frame, a feeding conveyor mechanism mounted on the top of the feeding frame, a lower printing frame mounted on one side of the feeding frame, an upper printing frame mounted on top of the lower printing frame, a screen frame mechanism mounted on one side of the upper printing frame, a lower feeding frame mounted on one side of the lower printing frame, an upper feeding frame mounted on top of the lower feeding frame, and a worktable mounted at the center of the top of the lower printing frame. This invention features a simple structure and low manufacturing cost, achieving automatic feeding, conveying, printing, and unloading of products. It improves the automation level of the equipment, increases work efficiency, reduces manual intervention, and lowers labor costs. Furthermore, the screen frame mechanism allows for easy inspection of the printing process after printing, greatly enhancing the practicality of the equipment.

[0004] Traditional photovoltaic glass screen printing equipment suffers from low efficiency, high idle rate due to single-station serial operation, unstable glass fixation causing printing deviation, and rough scraping process resulting in uneven silver paste thickness. Summary of the Invention

The servo motor drives the drive gear to rotate. The drive gear drives the rotating shaft to rotate via the driven gear. The rotating shaft drives the circular plate to rotate. The circular plate drives the vacuum fixing mechanism to rotate, thereby adjusting the angle of the vacuum fixing mechanism.

[0013] Preferably, the vacuum fixing mechanism includes a hollow box, which is fixedly installed on the top of the rotating shaft. The hollow box has a hollow structure, and multiple negative pressure holes are opened on the top of the hollow box. A vacuum pump is installed on the outside of the hollow box, and a vacuum tube is connected between the vacuum pump and the hollow box. A first solenoid valve is installed on the vacuum tube, and a frame is fixedly installed on the top of the hollow box. The vacuum pump operates to generate negative pressure through the vacuum tube, and the photovoltaic glass is attracted and fixed through the multiple negative pressure holes.

[0014] Preferably, the leveling mechanism includes a first rectangular base, which is fixedly installed on the top of the base.

Precise 90° rotation positioning reduces equipment downtime and improves efficiency.

[0023] 2. Quick angle switching: The servo motor and gear transmission drive the rotating shaft to ensure rapid switching of glass between printing and smoothing stations.

[0024] 3.

The vacuum pump independently controls the adsorption force, adapting to glass of different thicknesses to avoid cracking or warping.

[0025] 4. Precise printing pressure control: A second telescopic motor drives the ink cartridge and printing plate to vertically fine-tune the pressure, ensuring uniform contact between the screen and the glass. Dual second linear motors enable dynamic horizontal leveling of the printing plate, compensating for glass surface tolerances.

[0026] 5. Closed-loop ink supply system: The sealed pipeline from storage box to pressure pump to ink cartridge, combined with the second solenoid valve, precisely controls the ink volume, avoids air bubbles / ink interruption, and reduces silver paste waste.

[0027] 6. Adaptive scraping mechanism: The first telescopic motor drives the scraper plate to float vertically and press against the glass surface. The beveled design reduces scraper resistance and eliminates bubbles / wrinkles in the printed layer.

[0058] Specifically, printing unit 5 has the following core functions:

[0059] Positioning: The second lead screw 56 drives the printed circuit board 512 to move with a positioning accuracy of ±5μm;

[0060] Downward pressure: The second telescopic motor 510 controls the pressure of the printed circuit board contacting the glass to be 80-120N;

[0061] Ink supply: Pressure pump 514 pumps silver paste from storage box 517 into ink cartridge 511 at a pressure of 0.2-0.5MPa, and second solenoid valve 515 controls the flow rate with an error of ≤±1%.

[0062] Operating Procedure: During use, the photovoltaic glass is placed on top of the hollow box 31, inside the frame 32. The vacuum pump 36 generates negative pressure through the vacuum tube 34, attracting and fixing the photovoltaic glass through multiple negative pressure holes 33. The servo motor 23 drives the drive gear 24 to rotate, which in turn drives the rotating shaft 21 to rotate via the driven gear 22. The rotating shaft 21 drives the circular plate 25 to rotate, which in turn drives the vacuum fixing mechanism 3 to rotate 90 degrees. The vacuum fixing mechanism 3 moves the photovoltaic glass below the printing mechanism 5. The second telescopic motor 510 pushes the ink cartridge 511 and the printing plate 512 downwards, bringing the printing plate 512 into contact with the photovoltaic glass. The second motor 54 drives the second lead screw 56 to rotate, which in turn moves the printing plate 512 via the second moving plate 57, the second linear motor 58, and the second mounting plate 59. The two second linear motors 58 push the second mounting plate 59 to move the printing plate 512. The printing plate 512 moves, adjusting the position of the printing plate 512 and the photovoltaic glass to achieve printing on the photovoltaic glass. The pressure pump 514 works to send printing ink into the ink cartridge 511 through the suction tube 516, and then into the printing plate 512. The photovoltaic glass is screen-printed through the printing plate 512. After the photovoltaic glass is screen-printed, the vacuum fixing mechanism 3 is controlled to leave the printing mechanism 5, and another photovoltaic glass is replaced for screen printing. Then the screen-printed glass is moved to the position of the scraping mechanism 4, and the inclined surface 411 is brought into contact with the surface of the photovoltaic glass. The first motor 43 drives the first lead screw 45 to rotate. The first lead screw 45 drives the first moving plate 46 to move. The first moving plate 46 drives the scraper plate 410 to move through the first linear motor 47, the first mounting plate 48, and the first telescopic motor 49. The scraper plate 410 scrapes the photovoltaic glass flat. After the work is completed, the fixing of the photovoltaic glass is released, and the photovoltaic glass can be removed.

[0063] Example 2

[0064] Example 2 is the same as Example 1 in the rest, except that a resistor can be provided inside the scraper plate 410. The scraper plate 410 is heated by the resistor, and the photovoltaic glass is scraped flat after the scraper plate 410 is heated, thereby improving the drying speed of the photovoltaic glass.

[0065] In this embodiment, the ink cartridge 511 can integrate a heating module (PTC ceramic) and a temperature sensor to maintain a stable silver paste viscosity (25±1℃).

[0066] In this embodiment, the scraper plate 410 can be replaced with a piezoelectric ceramic scraper, which reduces the cohesion of the silver paste and eliminates microbubbles by vibrating at a frequency of 20-40kHz.
