Screen Printing Machine with CCD
Screen printing machines are called universal printing machines, which can print on a variety of substrates, with excellent printing quality and accurate images and text. Screen printing originated in my country and has a history of more than 2,000 years of development and application. Screen printing can be applied to various materials such as textiles, metals, plastics, ceramics, etc. It can be applied to various material forms such as plane, convex, concave, etc. It can be applied in many industries such as advertising, art, and electronics industry. The screen printing machine is also a printing machine with the highest degree of automation in the printing industry at home and abroad. The equipped optical vision alignment system further improves the printing precision of the printing machine. The screen printing machine can realize multi-color printing, and the visual alignment system is matched with the screen overprinting positioning marks of different printing colors, which can carry out high-accuracy automatic production. At present, the best screen printing machine can control the position adjustment time within 1 second, and the position accuracy can reach ±0.02mm. It uses fewer CCDs to obtain edge positioning, reduces real-time signal transmission costs, and reduces uncertain factors. The visual alignment of the screen printing machine is realized by CCD, and at least 4 CCDs can realize the edge image positioning. The cooperation of CCD with industrial telecentric lens, coaxial point light source and other visual equipment can further improve the accuracy, the theoretical accuracy can be increased to 0.00375mm, and a more accurate printed image edge can be obtained.
The specific application of the CCD optical vision alignment system in the automatic screen printing machine
The main responsibility of the CCD optical vision alignment system in the screen printing machine is to complete image recognition and visual positioning. Among them, edge recognition is very important and is an important link to improve the accuracy of screen printing. Visual positioning requires the cooperation of image processing and analysis technology to calculate the precise placement of the substrate. Edge vision needs to complete multiple steps such as image preprocessing, edge extraction, filtering, pixel processing, least squares fitting, etc., and finally obtain a more accurate edge line equation.

The Advantages of Screen Printing
Screen printing belongs to stencil printing, which is called the four printing methods together with lithography, embossing and gravure printing. Hole printing includes transcription, perforated pattern, spray and screen printing, etc. The principle of stencil printing is: the printing plate (the perforations that can pass ink are made on the base of the paper film plate or other plates). When printing, the ink is transferred to the substrate (paper, ceramics, etc.) through the perforations of the stencil under a certain pressure. ) To form an image or text.
The 2021 version of China's screen printing market special research analysis and development prospect forecast report released by Industry Research Network believes that the ink is transferred to the substrate through the mesh of the graphic part through the squeeze of the squeegee during printing, and the formation is the same as the original Graphic. The screen printing equipment is simple, convenient to operate, simple in printing and plate making, low in cost, and strong in adaptability. Screen printing has a wide range of applications.

The maintenance methods of screen printing machines
The maintenance methods of screen printing machines include:
daily maintenance, long-term maintenance, regular inspection and maintenance, and cleaning and maintenance steps.
Daily maintenance Before operating the screen printing machine, the operator should first check whether there is dust left by chips at the junction of the movable guide rail surface of the screen printing machine, and keep it free of oil stains, brushing, scratches and other phenomena
2. If the screen printing machine is not used for a long time, it should be wiped clean and placed in a cool, dry environment with good ventilation effect
3. Experienced operators should not disassemble the touch screen without the guidance of a professional master, because it is easy to damage the touch screen. Operators must regularly conduct condition surveys, accuracy inspections, and adjustments of screen printing machine equipment, and carry out fault analysis and condition monitoring
4. In the daily maintenance of the screen printing machine, it is strictly forbidden for the operator to disassemble the parts, and when the screen printing machine fails, the emergency stop switch must be pressed immediately and the main power supply must be turned off, and the maintenance personnel must be notified.
Cleaning and maintenance steps: Cleaning of the walking arm: first remove the cover, then check whether there are any debris on the walking arm track, clean up the debris with a duster, then use a brush to clean the debris in the gap, then scrub the track with an alcohol-free dust cloth, and then add some track oil to the track
5. Inspection of servo motor: manually control the motor movement, observe whether the motor movement is stable, touch the motor to see if there is heat, long-term movement will lead to loose transmission shaft connection, if necessary, adjust the motor PID parameters and adjust the level; Check whether the connecting belt of the motor is loose and broken, and adjust it if necessary
The working principle of the screen printing machine
The working principle of the screen printing machine ① The working cycle program of the flat screen flat screen printing machine takes the flat screen platform type monochrome semi-automatic hand screen printing machine as an example. One of its working cycles is: feeding parts → positioning → printing → Lower the squeegee, raise the ink return plate → Squeegee stroke → Raise the squeegee → Lower the ink return plate → Lift the plate → Return ink stroke → Release positioning → Receiving.
In the continuous cycle action, as long as the function can be realized, the time occupied by each action should be as short as possible to shorten the period of each work cycle and improve the work efficiency.
③ Embossing line. During the printing stroke, the squeegee squeezes the ink and the screen printing plate, so that the screen printing plate and the substrate form a contact line, which is called a nip line. This line is at the edge of the squeegee, and countless embossed lines form the printing surface. Achieving an ideal nip line is difficult because the printing stroke is a dynamic process.
③The working principle of screen printing machine. Taking the commonly used hand-shaped screen printing machine as an example, the working principle of the screen printing machine can be described as follows: the power is transmitted through the transmission mechanism, and the squeegee squeezes the ink and the screen printing plate during the movement, so that the screen printing The printing plate and the substrate form an embossing line. Since the screen has tensions N1 and N2, a force F2 is generated on the squeegee. Under the action of the squeezing force F1 of the squeegee, through the mesh, the printing is missed from the moving embossing line to the substrate.
During the printing process, the screen printing plate and the squeegee move relative to each other, and the extrusion force F1 and the rebound force F2 also move synchronously. Dirty blots. That is, the screen is constantly deformed and rebounded during the printing stroke.
The squeegee is separated from the substrate together with the screen printing plate after the one-way printing is completed, and at the same time, the ink is returned to the back, that is, a printing cycle is completed. The distance between the top of the substrate and the reverse side of the screen printing plate after returning to ink is called the same plate distance or screen distance, which should generally be 2 to 5 mm. In manual printing, the operator's technique and proficiency directly affect the formation of the embossing line. In practice, screen printing workers have accumulated a lot of valuable experience, which can be summarized into six points, that is, to ensure the linearity, uniformity, isometric, pressure equalization, centering and verticality in the movement of the squeegee. That is to say, the squeegee should move in a straight line during printing, and it should not be shaken left and right; it should not be slow forward and fast, fast forward and then slow or suddenly slow and fast; the inclination angle to the ink plate should remain unchanged, and special attention should be paid to overcoming the inclination angle. A common problem that gradually increases; the printing pressure should be kept uniform; the distance between the squeegee and the inner side of the screen frame should be equal; the ink plate and the frame should be kept perpendicular
