The pneumatic palletizing system is an important automated device in modern production and logistics. With its high efficiency, precision, and stability, it is widely used in various industries, improving production efficiency and reducing labor costs. By reasonably selecting appropriate pneumatic components and control systems, efficient stacking and handling of various materials can be achieved, ensuring the smooth operation of the production line.

[0016] As a further description of the above technical solution: A method for using a pneumatic palletizing device includes the following steps: S1. When it is necessary to palletize the glass plates on the conveyor belt, first install the non-woven fabric on the limiting rod, align the cloth winding sleeves wound at both ends of the non-woven fabric with the limiting rod and insert them. Then, under the action of the tension spring A, the limiting block is moved out to limit and fix the cloth winding sleeve; S2. Then, use the electric push rod to drive the pneumatic suction cup frame on the moving frame to move down. At this time, under the action of the fixed rack, the transmission wheel will rotate. At this time, the transmission wheel will drive the universal joint A to rotate, so that the universal joint A drives the connected reciprocating lead screw to rotate, so that the reciprocating lead screw drives the adjusting rack to move. At this time, the adjusting rack will drive the rotating rod connected to the adjusting wheel to rotate. Then, under the action of the spring B, the non-woven fabric is closely attached to the surface of the glass plate; S3. Then, under the action of the arc-shaped rack, the meshing grooved gear rotates. At this time, the grooved gear drives the turntable connected to the meshing teeth to rotate. At this time, the turntable drives the transmission sleeve to rotate, causing the transmission sleeve to drive the universal joint B connected to the transmission rod to rotate, making the universal joint B drive the transmission rod at the other end to rotate, and the transmission rod drives the driving wheel connected to the transmission sleeve to rotate.

[0017] S4. Then, driven by the driving wheel, the driven wheel rotates, causing the driven wheel to drive the connected worm to rotate, and the worm drives the two worm wheels to rotate, thereby driving the limit rod to rotate. The limit rod drives the cloth winding sleeve to rotate, so as to wind up the wiped non-woven fabric and pull out a new non-woven fabric for use. S5. At the same time, the convex disk connected and driven by the universal joint B rotates, causing the convex disk to press the contact rod. At this time, under the action of spring A, the movable frame moves reciprocally, enabling the non-woven fabric to wipe and clean the surface of the glass plate. Then, when the moving frame continues to move downward, the glass surface treatment mechanism rotates and resets, causing the pneumatic suction cup frame to adsorb on the glass plate. Then, the motor drives the connected rotating frame to rotate, and the glass plate is taken off the conveyor belt for palletizing.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: 1. In the present invention, by setting the glass surface treatment mechanism, before adsorbing and palletizing the glass plate with the pneumatic suction cup, driven by the adjustment mechanism, the glass surface treatment mechanism can swing, enabling the non-woven fabric to clean the surface of the glass plate, making the adsorption effect of the pneumatic suction cup more stable, reducing the air leakage during the adsorption of the pneumatic suction cup, and also avoiding the problem of insecure adsorption caused by dirt interference. It reduces the steps of manually cleaning the surface of the glass plate, saves time, and improves the overall efficiency of the production line.

[0019] 2. In the present invention, by setting the transmission mechanism, while the adjustment mechanism drives the glass surface treatment mechanism to swing and clean, the transmission mechanism drives the used non-woven fabric to be wound up and pulls out a clean non-woven fabric, effectively preventing secondary pollution of dirt. At the same time, the transmission mechanism drives the glass surface treatment mechanism to move reciprocally, realizing the reciprocating wiping of the non-woven fabric on the glass plate all the time, and can achieve efficient cleaning and improve the overall efficiency of the production line.

[0020] 3. In the present invention, by setting spring B in the rotating frame, the non-woven fabric is kept in contact with the surface of the glass plate, which can effectively prevent the non-woven fabric from loosening or shifting during the cleaning process, thus maintaining the continuity and stability of cleaning. At the same time, by setting a limit block on the limit rod, it is convenient to replace the non-woven fabric. Description of the Drawings

The transmission wheel 903 is meshed and driven with the fixed rack 402. Under the action of the fixed rack 402, the transmission wheel 903 will rotate.

Then, use the electric push rod 501 to drive the pneumatic suction cup holder 7 on the moving frame 6 to move downward. At this time, under the action of the fixed rack 402, the transmission wheel 903 will rotate. At this time, the transmission wheel 903 will drive the universal joint A902 to rotate, so that the universal joint A902 drives the connected reciprocating lead screw 904 to rotate, so that the reciprocating lead screw 904 drives the adjusting rack 905 to move.
