[0002] Automotive glass screen printing refers to the printing of patterns or text on the glass of the car through screen printing technology. This printing technology uses a screen to apply specific ink to the glass surface through the mesh to form the desired design. The screen printing ink is resistant to high temperatures, UV rays, and chemical corrosion, ensuring that the pattern remains clear and durable under the changing climate conditions inside the car.

[0003] The suction device for automotive glass screen printing is an auxiliary device used to ensure that the glass plate can remain flat and accurately positioned during the screen printing process, that is, to ensure the stability of the glass by suctioning it with negative pressure. During the screen printing process, due to the physical properties of the glass material, it may bend or shift, which will affect the printing quality and accuracy. The suction device for automotive glass screen printing is a key component to improve the quality and efficiency of screen printing, and is essential to ensure that the pattern on the car glass is clear and beautiful.

[0004] In the prior art, the leveling device is generally composed of a suction cup and a supporting structure. Vehicle glass such as the front windshield and the rear windshield generally has a certain bending angle, and different types of vehicle glass have different bending angles. In order to ensure stability, the supporting platform of the leveling device used in silk screen printing is generally set to a rigid platform or a supporting plane structure that matches the glass contact surface. This structure is not convenient for adjusting the structure of the leveling device according to the bending angle of the vehicle glass, resulting in insufficient adaptability and low flexibility of the leveling device.

[0025] See also Figure 1-4 As shown, the present invention is a suction leveling device for screen printing of curved vehicle-mounted glass, comprising a base 1, a positioning mechanism 5 for positioning the curved glass, and a pneumatic bag support assembly 3 for supporting the curved glass, the positioning mechanism 5 and the pneumatic bag support assembly 3 are both arranged on the base 1, the positioning mechanism 5 is provided with four groups, the four groups of positioning mechanisms 5 are symmetrically arranged on both sides of the pneumatic bag support assembly 3, and are distributed in a rectangular shape, each group of positioning mechanisms 5 includes a lifting assembly arranged on the base 1, and the output end of the lifting assembly is provided with a hinge shaft 503, and the hinge shaft 503 is fixedly connected There is a suction cup 504, and the effective height of the suction cup 504 is raised or lowered by a lifting component, and the angle of the suction cup 504 is adjusted to adapt to the curved panel surfaces on both sides of the curved glass, so that the curved glass can be fixed by the suction cup 504. After the curved glass is fixed on the suction cup 504, the volume of the air pressure bag support component 3 becomes larger after inflation, thereby achieving support for the curved glass, and the air pressure bag support component 3 is responsible for pushing the curved glass upward, and the suction cup 504 is responsible for fixing the position of the curved glass, and the two maintain a static balance, thereby ensuring the overall stability of the curved glass.

[0026] In the present invention, in order to facilitate the support of curved glass, the air pressure bag support assembly 3 includes a straight tube portion 301 and an arc portion 302 arranged above the straight tube portion 301. The top of the arc portion 302 is arranged in an arc shape. The arc portion 302 facilitates the air pressure bag support assembly 3 to adapt to the arc-shaped bottom surface of the curved glass. An air pressure control device is arranged on the base 1. The output end of the air pressure control device is connected to the air pressure bag support assembly 3. The air pressure control device is responsible for inflating the air pressure bag support assembly 3, thereby providing upward pressure to the curved glass.

[0027] In the present invention, in order to prevent the air pressure bag support assembly 3 from damaging the curved glass, an air pressure sensor 4 is fixedly connected to the air pressure bag support assembly 3. The air pressure sensor 4 is responsible for monitoring the pressure inside the air pressure bag support assembly 3 to prevent the pressure inside the air pressure bag support assembly 3 from being too high, causing the force applied to the curved glass to exceed the range that the curved glass can withstand, thereby causing damage to the glass.

[0028] In the present invention, in order to improve the fixing effect of the curved glass, a supporting soft board 505 is fixedly connected to the hinge shaft 503, and the suction cup 504 is located in the middle of the supporting soft board 505. The supporting soft board 505 enables the suction cup 504 to maintain an optimal fitting angle with the curved glass to improve the fixing effect of the suction cup 504 and realize automatic adjustment of the adsorption angle of the suction cup 504.

[0029] In the present invention, in order to realize the lifting and lowering of the suction cup 504, each group of lifting components includes an electric telescopic rod 502, each group of electric telescopic rods 502 is fixedly connected to the base 1, and the hinge shaft 503 is fixedly connected to the telescopic end of the electric telescopic rod 502. The position of the suction cup 504 is adjusted by extending or contracting the electric telescopic rod 502, so that the suction cup 504 cooperates with the air pressure bag support assembly 3 to support the curved glass.

[0030] In the present invention, in order to achieve the storage of the supporting soft board 505 and the suction cup 504, a protective sleeve 501 is fixedly sleeved on the outer side of each set of electric telescopic rods 502, and a storage groove 506 matching the supporting soft board 505 and the suction cup 504 is opened on the protective sleeve 501.

[0033] The working principle of the present invention is as follows: the electric telescopic rod 502 is used to raise or lower the working height of the suction cup 504, and the curved glass is placed on the four groups of suction cups 504. At this time, the supporting soft board 505 will automatically adjust the working angle between the suction cup 504 and the curved glass, so that the suction cup 504 and the curved glass maintain an optimal fitting angle to improve the fixing effect of the suction cup 504. After the curved glass is fixed on the suction cup 504, the booster pump 2 is an air pressure bag support component 3. The volume of the air pressure bag support component 3 increases after being inflated. The top of the air pressure bag support component 3 is provided with an arc-shaped portion 302, which is convenient for the air pressure bag support component 3 to adapt to the arc-shaped bottom surface of the curved glass, and the air pressure is used to support the curved glass. The pressure sensor 4 is responsible for monitoring the pressure inside the air bag support assembly 3 to prevent the pressure inside the air bag support assembly 3 from being too high, causing the force applied to the curved glass to exceed the range that the curved glass can withstand, causing damage to the glass. The air bag support assembly 3 is responsible for pushing the curved glass upward, and the suction cup 504 is responsible for fixing the position of the curved glass. The two maintain a static balance to ensure the stability of the curved glass. After use, the supporting soft board 505 and the suction cup 504 can be driven to be directly stored in the storage groove 506, and the protective sleeve 6 can be sleeved on the protective sleeve body 501, so as to isolate the suction cup 504 from the outside world and prevent the suction cup 504 from being contaminated;
