1. A method for gluing front and rear windshields of an automobile by an automatic gluing machine is characterized by comprising the following steps:

A. the windshield is grabbed and placed on the base coat rotary table (14), the first air cylinder (17) drives the base coat rotary table (14) to ascend, the first suction disc (15) sucks the windshield on the first air cylinder to perform base coat operation, the base coat rotary table (14) descends to avoid the air after the base coat operation is finished, and then the windshield is manually pushed forwards through the first conveying line (10);

B. after the windshield is pushed to the transmission roller conveying line (101), the transmission roller conveying line (101) inclines towards the direction of the next station around a first hinge point (104) under the gravity of the windshield, the windshield slides along an inclined plane to impact a baffle plate (105) and simultaneously triggers a third travel switch (110) to finish the coarse positioning of the width direction of the windshield, only the second travel switch (109) is triggered to be a rear windshield, the first travel switch (108) and the second travel switch (109) are triggered to be a front windshield, the windshield is distinguished and fed back to an electric control system, on the coarse positioning device (1), the windshield starts to be dried by the first drying pipeline (202), after the windshield at the next station finishes the operation, the driving roller conveying line (101) descends to avoid the windshield, and the windshield is placed on the second conveying line (9) and conveyed to the glass centering station;

C. at a glass centering station, the ejector rod (301) rises to jack the windshield on the second conveying line (9), the two first damping cylinders (303) swing upwards around a second hinge point (307) to position the rear end of the windshield, the two second damping cylinders (304) descend to position the front end of the windshield, and the two third damping cylinders (305) synchronously move in opposite directions to position two sides of the windshield; the cylinder adopts a high-pressure loop during centering, then the measurement is switched to a low-pressure loop, the size of the windshield is measured by the cylinder with the encoder, and the size is fed back to the gluing robot (13); while the centering is performed, the second drying pipeline (203) also dries the windshield;

D. after centering, the rear windshield is distinguished by the coarse positioning device (1), a third sucker (402) of the rear windshield conveying device (4) ascends to suck the rear windshield, the ejector rod descends to reset, each damping cylinder loosens the windshield and resets, and the third sucker (402) moves along the fourth guide rail (401) to convey the rear windshield to a gluing station of a third conveying line (11); the front windshield is distinguished by the coarse positioning device (1), a second sucker (502) of the front windshield conveying device (5) ascends to suck the front windshield, the ejector rod descends to reset, each damping cylinder loosens the windshield and resets, and the second sucker (502) moves along a third guide rail (501) to convey the rear windshield to a gluing station of a third conveying line (11);

F. at the gluing station, a gluing robot (13) glues the windshield according to the glass model fed back by the centering station and a prestored gluing track;

G. after the gluing operation is finished, the second suction cup (502) or the third suction cup (402) is disconnected with air, loosened, lowered and reset, and the third conveying line (11) conveys the windshield to a glass overturning station;

H. after the fourth sucking disc (603) sucks the rear windshield, the rotary lifting device (6) horizontally rotates the rear windshield for 180 degrees and then lifts the rear windshield, and if the rear windshield is the front windshield, the step is skipped;

I. the fifth suction cup (705) descends to suck the windshield, the fourth suction cup (603) is released and reset, and the second motor (701) drives the eleventh air cylinder (704) to turn the windshield by 180 degrees and lift the windshield;

J. the sixth suction cup (807) descends to suck the windshield and then ascends, the fifth suction cup (705) is released and reset, and the third motor (805) drives the driving wheel (806) to move on the transverse rail (801) to transfer the windshield to the next station for installation.
