Description

Technical Field

[0001] This invention relates to the field of aluminum processing equipment technology, specifically to a continuous aluminum grinding production line based on aluminum surface treatment technology. Background Technology

[0002] Currently, aluminum surface treatment processes are widely used in various industries such as aerospace, automotive manufacturing, and building decoration to improve the appearance quality, corrosion resistance, and service life of aluminum materials. Traditional aluminum surface polishing processes mostly rely on manual operation or semi-automated equipment, which presents many problems.

[0003] Manual polishing is labor-intensive, and inconsistent skill levels and efficiency can lead to uneven polishing of aluminum surfaces, affecting product quality. Traditional equipment is often single-function and lacks automation, resulting in low production efficiency. Furthermore, manual operation is susceptible to environmental factors and differences in operator skill, making it impossible to ensure consistent surface treatment results. While existing continuous aluminum production lines have introduced automated equipment such as feeding machines and polishing machines, they are mostly concentrated on single processes. The overall process suffers from bottlenecks in the connection between feeding, polishing, cleaning, and unloading, leading to an inefficient production flow and risks to surface quality assurance. In addition, if the waste and residue generated during polishing are not cleaned up in time, it will affect the results of subsequent processes.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: As Figures 1-8 As shown, this embodiment of the invention provides a continuous aluminum grinding production line based on aluminum surface treatment technology, including: The conveyor belt 1 is used to transport aluminum materials to be processed. A cleaning component is installed on one side of the top of the conveyor belt 1. The cleaning component is used to clean the surface of the aluminum materials to be processed. The conveyor belt 13 is also included for automatically unloading the processed aluminum materials. The output end of the conveyor belt 13 is connected to a placement rack 5. The cleaning component includes a drive rack 901, which is fixedly connected to one side of the top of the conveyor belt 1. A limit groove 905 is opened on the top of the drive rack 901. A limit frame 902 is slidably connected inside the limit groove 905. A second servo motor 903 is fixedly connected to the top of the limit frame 902. A drive gear 904 is fixedly connected to the output end of the second servo motor 903. A cleaning brush 906 is slidably installed on the outside of the drive rack 901.

[0020] Specifically, by starting the second servo motor 903, the drive gear 904 is driven to rotate. Since the drive gear 904 is meshed with the outer side of the drive rack 901, when the drive gear 904 rotates, the limit frame 902 moves along the inner wall of the limit groove 905. The movement of the limit frame 902 drives the connecting shell 401 and the cleaning brush 906 to move synchronously. The movement of the cleaning brush 906 is used to remove dust from the outer surface of the aluminum material.

[0021] The outer side of the drive gear 904 meshes with the outer side of the drive rack 901, and the cleaning brush 906 is installed at the bottom of the connecting housing 401.

[0022] The collection hopper 3 stores cleaning fluid inside. A cleaning assembly is installed on the top of the collection hopper 3. The cleaning assembly is used to clean the polished aluminum material. A filter screen is installed on the inner side of the collection hopper 3. One end of the first transport pipe 602 is connected to the outer side of the collection hopper 3, and the other end of the second transport pipe 603 is connected to the outer side of the water spray pipe 604.

[0023] The cleaning assembly includes a support frame 605, which is fixedly connected to the top side of the collection hopper 3. A fixing frame 606 is fixedly connected to the top of the support frame 605. A water spray pipe 604 is installed at the bottom of the fixing frame 606. A pump body 601 is installed on the outside of the collection hopper 3. A second transport pipe 603 is fixedly connected to the output end of the pump body 601, and a first transport pipe 602 is fixedly connected to the input end of the pump body 601.

[0024] An automatic grinding assembly is used to automatically grind aluminum materials to be processed. A chip blowing assembly is installed on the outside of the automatic grinding assembly. The chip removal assembly includes a fixed post 801 and a rotating disk 802. The fixed post 801 is fixedly connected to the outside of the mounting bracket 2. A rubber piston 808 is slidably connected inside the fixed post 801. A movable rod 804 is fixedly connected to the outside of the rubber piston 808. An air inlet pipe 806 is connected to the outside of the fixed post 801. A conveying pipe 805 is also connected to the outside of the fixed post 801. A one-way valve 807 is installed on the inside of both the air inlet pipe 806 and the conveying pipe 805. An air jet pipe 809 is fixedly connected to one end of the conveying pipe 805. The rotating disk 802 is fixedly connected to one end of the drive screw 702. A swing rod 803 is rotatably connected to the eccentric part of the outside of the rotating disk 802. One end of the swing rod 803 is rotatably connected to the end of the movable rod 804. The two one-way valves 807 have opposite conduction directions.

[0025] Specifically, when the drive screw 702 starts to rotate, it drives the rotating disk 802 to rotate synchronously. Due to the eccentric design of the rotating disk 802, the rotation of the rotating disk 802 causes the swing rod 803 to rotate eccentrically, which in turn drives the movable rod 804 to move up and down. The up and down movement of the movable rod 804 directly drives the movement of the rubber piston 808. Specifically, when the movable rod 804 moves downward, the rubber piston 808 is pressed downward, causing a negative pressure to be generated inside the fixed column 801. At this time, external air enters the interior of the fixed column 801 through the air intake pipe 806.

[0026] As the movable rod 804 continues to move upward, the rubber piston 808 rises accordingly, and the air inside the fixed column 801 flows out through the transmission pipe 805, passes through the one-way valve 807, and enters the jet pipe 809. At the end of the jet pipe 809, the airflow is ejected and accurately blown onto the surface of the grinding disc 708, removing the debris and dust generated during the grinding process.

[0027] The action of the chip blowing assembly is periodic and repeated continuously. Each time the movable rod 804 moves up and down, the airflow changes. Through the combined action of the air intake pipe 806 and the air jet pipe 809, it ensures that the debris on the surface of the grinding disc 708 is cleaned in a timely manner, preventing the accumulation of debris from affecting the grinding effect.

[0028] The automatic grinding assembly includes a mounting frame 2. A first servo motor 701 is mounted on the outside of the mounting frame 2. A drive screw 702 is fixedly connected to the output end of the first servo motor 701. A threaded bracket 703 is threadedly connected to the outside of the drive screw 702. A connecting bracket 705 is fixedly connected to the outside of the threaded bracket 703. A cylinder 704 is mounted on the outside of the connecting bracket 705. A grinding motor 707 is fixedly connected to the output end of the cylinder 704. A grinding disc 708 is fixedly connected to the output end of the grinding motor 707. A fixing ring 709 is fixedly connected to the outside of the grinding disc 708. An electric telescopic rod 706 is mounted on the outside of the connecting bracket 705. The free end of the electric telescopic rod 706 is rotatably connected to the outside of the fixing ring 709. A guide rod 14 is slidably connected to the upper through hole inside the threaded bracket 703. Both ends of the guide rod 14 are fixedly connected to the inside of the mounting frame 2.

[0029] Specifically, mounting bracket 2 serves as the supporting foundation for the entire automatic grinding assembly, and all other components are fixed via mounting bracket 2. A first servo motor 701 is mounted on the outer side of mounting bracket 2, providing power. Its output end is fixedly connected to drive screw 702. Drive screw 702 acts as a transmission component, rotating to drive threaded bracket 703 to reciprocate left and right along its outer wall, thereby achieving translation of the grinding device. A connecting bracket 705 is fixedly connected to the outer side of threaded bracket 703, serving as a bridge connecting other mechanisms and ensuring the stable operation of the entire grinding assembly.

[0030] Cylinder 704 is mounted on the outside of the connecting bracket 705. The function of cylinder 704 is to adjust the position of the grinding disc 708 by generating reciprocating motion. A grinding motor 707 is fixedly connected to the output end of cylinder 704, and a grinding disc 708 is fixedly connected to the output end of grinding motor 707. The grinding disc 708 is rotated by electric drive. With the precise control of cylinder 704, the surface of the grinding disc 708 is brought into close contact with the surface of the aluminum material, thereby performing a uniform and efficient grinding operation.

[0031] In addition, a through hole is provided on the upper side of the threaded bracket 703, and the guide rod 14 is slidably connected in the through hole. The two ends of the guide rod 14 are fixedly connected to the inner side of the mounting bracket 2. The function of the guide rod 14 is to ensure the stable movement of the threaded bracket 703, avoid uneven grinding effect due to movement deviation, and ensure the accuracy and stability of the entire grinding process.

[0032] Example 2: Automatic gripping component, used to grip aluminum material to be processed.

[0033] The automatic gripping component includes an electric turntable 10, a robotic arm 11 mounted on the top of the electric turntable 10, an electric suction cup 12 mounted on the end of the robotic arm 11, a collection bin 403 also mounted on the top of the electric turntable 10, a dust collector 405 mounted on the outside of the collection bin 403, a second connecting pipe 404 fixedly connected to the input end of the dust collector 405, a first connecting pipe 402 fixedly connected to the output end of the dust collector 405, a connecting shell 401 mounted on the end of the first connecting pipe 402, and the end of the second connecting pipe 404 away from the dust collector 405 connected to the outside of the collection bin 403.

[0034] Specifically, the electric turntable 10 is installed at the center of the processing line and has adjustable speed and rotation functions. It is used to orient and deliver aluminum materials to the position of the robotic arm 11. The robotic arm 11 is fixedly installed on the top of the electric turntable 10. The robotic arm 11 can move in multiple directions, including up and down, left and right, and rotation, within a predetermined range to ensure accurate gripping, positioning, and handling of aluminum materials. An electric suction cup 12 is installed at the end of the robotic arm 11. The suction force of the electric suction cup 12 is adjusted by the control system and can be adaptively adjusted according to the surface characteristics of the aluminum material to ensure firm adhesion to the aluminum surface.

[0035] During this process, the first connecting pipe 402 is connected to the output end of the dust collector 405, and the sucked-in dust and debris are guided into the collection bin 403 through the negative pressure. Simultaneously, the second connecting pipe 404 connects the collection bin 403 and the dust collector 405, ensuring that the dust is effectively sucked away from the cleaning brush 906 and guided into the collection bin 403. The end of the second connecting pipe 404 furthest from the dust collector 405 is connected to the outside of the collection bin 403, and the dust accumulated during the cleaning process is guided into the collection bin 403 through negative pressure.

[0036] Specifically, the conveyor belt 13 is made of high-strength, wear-resistant material, capable of withstanding long-term, high-frequency use to ensure stable transportation of aluminum materials. During the conveying process, the speed of the conveyor belt 13 can be adjusted according to the progress of aluminum material processing to adapt to different production needs. The placement rack 5 is connected to the automatic unloading system through an intelligent control system, enabling automatic unloading when the aluminum material reaches the designated position, avoiding errors and labor intensity during manual handling. In addition, the placement rack 5 is designed with appropriate space and support structure to accommodate the simultaneous stacking of multiple aluminum materials, further improving the overall efficiency and operational continuity of the production line. Through coordination with other automated processes, the conveyor belt 13 and placement rack 5 can achieve efficient and seamless transfer of aluminum materials, reducing the need for manual intervention and improving the automation level and stability of the production process.

[0037] Working principle: When using this device, the conveyor belt 1 is started to transport the aluminum material to be processed. At the same time, the second servo motor 903 is started to drive the drive gear 904 to rotate. Since the drive gear 904 is meshed with the outer side of the drive rack 901, when the drive gear 904 rotates, the limit frame 902 moves along the inner wall of the limit groove 905. The movement of the limit frame 902 drives the connecting shell 401 and the cleaning brush 906 to move synchronously. The movement of the cleaning brush 906 removes the dust from the outer surface of the aluminum material. In addition, the dust collector 405 is started to create a negative pressure inside the collection bucket 403, which allows the dust inside the cleaning brush 906 to enter the collection bucket 403 through the first connecting pipe 402 and the second connecting pipe 404, ensuring the cleaning effect of the cleaning brush 906. After processing, the electric suction cup 12 is attached to the outer surface of the aluminum material by the robot arm 11, and the aluminum material is adsorbed by the electric suction cup 12. After adsorption, the clamped aluminum material is moved to the grinding component by the electric turntable 10. By activating the first servo motor 701, the drive screw 702 rotates, causing the threaded bracket 703 to reciprocate left and right along the outer wall of the drive screw 702. Simultaneously, by activating the grinding motor 707, the grinding disc 708 rotates, and in conjunction with the cylinder 704, the grinding disc 708 is moved to the outer surface of the aluminum material for grinding. Furthermore, by activating the electric telescopic rod 706, the fixed ring 709 swings, causing the grinding disc 708 to deflect at an angle, thus achieving all-around grinding of the aluminum material. When the drive screw 702 rotates, it synchronously rotates the rotating disk 802, causing one end of the swing rod 803 to rotate eccentrically. At this time, the swing rod 803 is pulled... Under the action of force, the movable rod 804 moves up and down. When the movable rod 804 moves down, it will drive the rubber piston 808 to move down. At this time, the inside of the fixed column 801 is in a negative pressure state. At this time, the outside air enters the inside of the fixed column 801 through the air inlet pipe 806. When the rubber piston 808 moves up, the air inside the fixed column 801 is injected into the inside of the jet pipe 809 through the transmission pipe 805 and discharged through the jet pipe 809. The airflow is sprayed on the outer surface of the polishing disc 708. In this way, by removing the waste on the polishing disc 708 in real time, the polishing disc 708 is kept clean at all times, which improves the stability and consistency of the polishing effect and thus improves the surface treatment quality of the aluminum material. At this time, the polished aluminum material is moved to the cleaning assembly by the electric turntable 10. The cleaning liquid inside the collection hopper 3 is transported to the second transport pipe 603 through the first transport pipe 602 by the pump body 601. Then, it is transported to the water spray pipe 604 through the second transport pipe 603 and the cleaning liquid is sprayed out through the water spray pipe 604 to clean the polished aluminum material, prevent waste from affecting subsequent processes or causing secondary pollution, and thus ensure the cleanliness and tidiness of the aluminum material surface. After the aluminum material is cleaned, it is moved to the top. At this time, the electric suction cup 12 stops working and the aluminum material is placed on the outer surface of the conveyor belt 13. Under the transportation of the conveyor belt 13, the aluminum material is placed on the placement rack 5 for centralized collection.
