Description

Technical Field

[0001] This utility model relates to the field of aluminum processing, specifically a pneumatic flipping mechanism for aluminum processing. Background Technology

[0002] In the aluminum processing industry, pneumatic flipping mechanisms are widely used in material flipping and transfer processes to meet the needs of different processing stages. Currently, traditional pneumatic flipping mechanisms for aluminum processing mostly use a method of directly picking up aluminum materials on a conveyor belt using vacuum suction cups.

[0003] In practical applications, these types of mechanisms lack a dedicated aluminum positioning structure. Due to speed fluctuations and vibrations during conveyor belt operation, and the difficulty in achieving a completely uniform initial placement of the aluminum material on the conveyor belt, positional deviations easily occur when the vacuum suction cup picks up the aluminum material, sometimes resulting in misalignment or even empty suction. This lack of pre-positioning of the aluminum material leads to unstable aluminum material posture during subsequent flipping processes, affecting processing accuracy and resulting in inconsistent aluminum material processing quality and a high scrap rate. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatic flipping mechanism for aluminum processing, so as to solve the problem of positional deviation that easily occurs during the suction of traditional pneumatic flipping mechanisms for aluminum mentioned in the background art.

[0006] Preferably, the pneumatic actuator includes a cylinder and a drive shaft rotatably mounted on the top of the housing. The flip plate is fixedly connected to the drive shaft, a gear is fixedly sleeved on the side wall of the drive shaft, and a rack that meshes with the gear is fixedly mounted on the output end of the cylinder.

[0007] Preferably, the swing arm is rotatably mounted on both sides of the flip plate, and the swing arm and the flip plate are respectively provided with round holes for hooking the tension spring.

[0008] Preferably, the top of the flip plate is provided with a plurality of mounting slots for accommodating the vacuum suction cup.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a pneumatic flipping mechanism for aluminum processing, including a conveyor belt and a housing 1. The conveyor belt is existing technology. The housing 1 is set between two sets of conveyor belts to form a conveying line. The movement of the conveyor belt drives the aluminum material to move along a preset direction. A flipping plate 3 is rotatably mounted on the top of the housing 1 through a pneumatic actuator. The pneumatic actuator includes a cylinder 10 and a drive shaft 2 rotatably mounted on the top of the housing 1. The flipping plate 3 is fixedly connected to the drive shaft 2. A gear 8 is fixedly sleeved on the side wall of the drive shaft 2. A rack 9 that meshes with the gear 8 is fixedly mounted on the output end of the cylinder 10. The gear 8 and rack 9 transmission has the characteristics of accurate transmission ratio and high transmission efficiency. Combined with the linear drive of the cylinder 10, it can stably convert the linear motion of the cylinder 10 into the rotational motion of the flipping plate 3, realize the precise control of the angle of the flipping plate 3, avoid the situation of incomplete or excessive flipping, and ensure the consistency and reliability of each action.

[0024] Please see Figures 2-6Several vacuum suction cups 6 for picking up aluminum are fixedly installed on the top of the flip plate 3. The top of the flip plate 3 has several mounting slots for accommodating the vacuum suction cups 6. The vacuum suction cups 6 adopt existing technical structures known in the art. Each vacuum suction cup 6 is fixed to the top surface of the flip plate 3 by bolt assemblies or adhesive bonding. Their arrangement density is optimized according to the weight and size parameters of the aluminum material. Each vacuum suction cup 6 is connected to a vacuum generating device (not shown in the prior art diagram) inside the housing 1 via an air guide pipe. When the vacuum generating device is activated, a negative pressure chamber is formed on the adsorption surface of the vacuum suction cup 6, thereby tightly adsorbing the surface of the aluminum material and preventing the aluminum material from slipping or falling off during transmission. Swing arms 4 are movably installed on both sides of the flip plate 3 via tension springs 11, forming a swingable connection structure. The swing arms 4 are rotatably mounted on both sides of the tilting plate 3. Both the swing arms 4 and the tilting plate 3 have circular holes for hooking the tension springs 11. A pulley 5 is rotatably mounted between the pair of swing arms 4 via a rotating shaft. The pulley 5 contacts the conveyor belt and drives the rotating shaft to rotate with the movement of the conveyor belt. A centering assembly is also provided between the pair of swing arms 4, connected to the rotating shaft. Notably, a positioning key is located on the side wall of the tilting plate 3 below the rotating shaft. In the initial state, the bottom of the swing arms 4 contacts the positioning key, and both ends of the tension springs 11 are hooked into the circular holes of the tilting plate 3 and the swing arms 4, respectively. In its initial installation state, it maintains a certain amount of tension, ensuring that the swing arms 4 always have a tendency to swing outwards under the tension of the tension springs 11. This guarantees the continuous and tight contact between the pulleys 5 and the conveyor belt, improving the reliability and adaptability of the device.

[0025] Please see Figures 6-8 The centering assembly includes a crossbar 7 fixedly installed between the swing arms 4. A pair of sliding sleeves 15 are rotatably fitted onto the side wall of the crossbar 7. A spring 14 connects the sliding sleeves 15 and the crossbar 7. A fixed rod 13 and an L-shaped rod 16 are fixedly installed on the side wall of the sliding sleeves 15. The top of the crossbar 7 has a pair of through holes for accommodating the fixed rod 13. The fixed rod 13 extends through the through holes, and the L-shaped rod 16 extends to contact the rotating shaft. An inclined plate 12 is fixedly fitted onto the side wall of the rotating shaft. The inclined plate 12 is eccentrically positioned. The side wall of the sliding sleeve 15 is integrally formed with mounting ears. The two ends of the spring 14 are fixedly connected to the crossbar 7 and the mounting ears, respectively. The L-shaped rod 16 extends through the spring 14 to abut against the inclined plate 12. When the pulley 5 moves with the conveyor belt and drives the rotating shaft to rotate, the eccentrically positioned inclined plate 12 synchronously performs circular motion. The contact point between the inclined plate 12 and the L-shaped rod 16 changes periodically with the rotation angle, thereby driving the fixed rod 13 to reciprocate around the sliding sleeve 15. When the aluminum material is conveyed to the flipping plate 3, the swing of the fixing rod 13 can apply a pushing force to the side of the aluminum material. Through the coordinated action of the fixing rods 13 arranged symmetrically on both sides, the aluminum material is pushed to the center position of the flipping plate 3, thereby realizing the centering function of the aluminum material.

[0026] This application uses a conveyor belt to drive the pulley 5 to rotate, which in turn drives the eccentric inclined plate 12 to perform circular motion, realizing the reciprocating swing of the fixed rod 13, and automatically pushing the aluminum material to the center position of the flipping plate 3. This process requires no manual intervention, solving the problem of large positioning errors in traditional pneumatic flipping mechanisms, effectively improving the positioning accuracy of the aluminum material during processing, ensuring the accuracy and consistency of subsequent processing steps, and reducing the product scrap rate.
