Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel processing technology, and in particular to a stain-resistant aluminum single-panel surface treatment device. Background Technology

[0002] Aluminum single-layer panels, as a commonly used building decoration material, are widely used in building curtain walls, interior and exterior decoration, and other fields due to their advantages such as light weight, high strength, and good weather resistance. In order to enhance their stain resistance, corrosion resistance, and meet aesthetic requirements, aluminum single-layer panels need to undergo surface treatment after forming. Among them, electrostatic spraying is one of the key processes. Currently, existing aluminum single-layer panel surface treatment equipment usually uses a conveyor belt system for conveying, with manual or simple robotic arms for feeding, and then spraying at fixed spraying stations.

[0003] Chinese patent CN221455270U4 discloses an aluminum panel surface treatment device. The device uses a grinding wheel, a spray nozzle and a conveyor belt to grind the aluminum panel. When grinding the aluminum panel, the device collects the impurities that are scattered around by spraying water in an atomized manner and collects them in a collection tank, thereby avoiding the health hazards to the workers on the work site caused by the scattered impurities.

[0004] The above-mentioned technical solutions rely heavily on single-function conveyor belts for feeding, which makes it difficult to achieve continuous automated cycles of material picking, transfer, positioning, spraying, and unloading. This results in slow production cycles, low efficiency, and high manual intervention, increasing labor costs and operational instability. The simple mechanical structure makes it difficult to ensure that the aluminum panels have a precise and repeatable spatial posture at the spraying station. Even slight deviations in the position or angle of the panels can lead to uneven spraying and inconsistent coating thickness, directly affecting the final anti-stain effect and product appearance quality. Therefore, the present invention solves the shortcomings of the above-mentioned technical problems. Utility Model Content

[0005] Based on the aforementioned technical problems, this utility model proposes a surface treatment device for anti-stain aluminum single-panel.

[0006] This utility model proposes a surface treatment device for anti-stain aluminum panels, including a conveyor belt for conveying the surface-treated aluminum panels. An electrostatic spray gun and a feeding bin are respectively provided on one side of the conveyor belt via support beams. A support side plate is also provided on one side of the conveyor belt, and a circulating material handling mechanism is provided on one side of the support side plate. The circulating material handling mechanism includes a vacuum suction cup. The vacuum suction cup sequentially picks up the stacked aluminum panels in the feeding bin, and after circumferential revolution, rotates to the side of the electrostatic spray gun for electrostatic spraying. The sprayed aluminum panels are placed on the upper surface of the conveyor belt for conveying.

[0007] Preferably, the circulating material handling mechanism further includes a support shaft rotatably connected to one side surface of the support side plate via bearings, a support plate is fixedly sleeved on the outer surface of the free end of the support shaft, and the surfaces of the three extended support plates of the support plate are rotatably connected to a linkage shaft via bearings.

[0008] Through the above technical solution, in order to realize the circumferential revolution of the vacuum suction cup and enable it to complete the cyclic loading and unloading action of aluminum panels, a rotary support platform is formed by the support shaft, support plate and linkage shaft. This allows the vacuum suction cup to cyclically stop at three stations: the unloading bin, the electrostatic spray gun and the conveyor belt. The linkage shaft rotates the housing to realize the rotation of the vacuum suction cup, so that the vacuum suction cup rotates at a certain angle on one side of the unloading bin, the electrostatic spray gun and the conveyor belt, so that it can complete the loading and unloading of aluminum panels.

[0009] Preferably, the circulating material handling mechanism further includes a rotating plate fixedly sleeved on the outer surface of the free end of the linkage shaft. The free end surface of the rotating plate is rotatably connected to an installation shaft. The outer surface of the end of the installation shaft away from the support side plate is fixedly connected to the outer surface of the frame of the vacuum suction cup through a connecting pipe fixedly sleeved on its outer surface.

[0010] The above technical solution achieves the material picking and unloading actions by setting a rotating plate at the free end of the linkage shaft and rotating the mounting shaft at the free end of the rotating plate. This allows the vacuum suction cup to be linked with the mounting shaft through the connecting pipe. When the vacuum suction cup revolves around different work positions, it can independently rotate at a certain angle, flexibly adjusting the posture of the vacuum suction cup so that it can adsorb aluminum panels on one side. This solves the alignment deviation problem caused by picking and unloading materials at a fixed angle, ensuring the accuracy of material picking, spraying, and unloading operations.

[0011] Preferably, the circulating material handling mechanism further includes a synchronous wheel that is fixedly sleeved on the outer surface of the linkage shaft and the outer surface of the mounting shaft, and the outer surfaces of the two synchronous wheels are connected by a synchronous belt.

[0012] Through the above technical solution, the synchronous belt and synchronous pulley transmit power through tooth meshing, which has the characteristic of zero slippage. It can strictly ensure that the speed ratio between the linkage shaft and the mounting shaft is constant. In the circulating material handling mechanism, this design makes the vacuum chuck highly synchronized in the process of station switching during revolution and angle adjustment during rotation.

[0013] Preferably, the circulating material handling mechanism further includes a transmission shaft rotatably connected to the surfaces of three extended support plates of the support plate via bearings. Both ends of the transmission shaft are respectively fixedly connected to a transmission gear and a meshing gear. Another meshing gear is fixedly sleeved on the outer surface of the linkage shaft, and the two meshing gears mesh.

[0014] With the above technical solution, in order to realize the rotation of the vacuum chuck, the rotation of the transmission shaft drives the meshing gear at one end to rotate, and the meshing of the other meshing gear can realize the rotation of the linkage shaft. The rotation of the linkage shaft, in turn, drives the installation shaft to rotate the vacuum chuck through the synchronous belt and synchronous pulley. In the circulating material handling mechanism, this design makes the position error of the vacuum chuck extremely small when switching work positions, avoids positioning deviation caused by transmission slippage, and ensures precise synchronization of material handling, spraying, and unloading actions.

[0015] Preferably, the circulating material handling mechanism further includes a fixed gear rotatably sleeved on the outer surface of the supporting shaft, and the plurality of transmission gears mesh with the fixed gear.

[0016] Through the above technical solution, the fixed gear is used as a reference component, and the power is synchronously transmitted to multiple transmission gears through meshing relationship, ensuring that the speed ratio of each transmission shaft is strictly constant. During the cyclic material picking process, this characteristic makes the position error of the vacuum chuck extremely small when switching stations, avoiding positioning deviation caused by transmission slippage, and achieving precise synchronization of material picking, spraying, and unloading actions.

[0017] Preferably, a geared motor is fixedly connected to one side surface of the support side plate, a drive gear is fixedly connected to the outer surface of the output shaft of the geared motor, and a driven gear is fixedly sleeved on the outer surface of the support shaft, with the drive gear meshing with the driven gear.

[0018] In order to achieve the rotation of the support shaft through the above technical solution, that is, to realize the revolution of the vacuum suction cup driven by the support plate, the geared motor realizes the rotation of the support shaft through the meshing of the drive gear and the driven gear, thereby completing the continuous picking and unloading of aluminum panels.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting up a circulating material handling mechanism consisting of a support shaft, support plate, linkage shaft, transmission gear set and synchronous belt pulley mechanism, the fully automated continuous cycle operation of aluminum single panel from loading, spraying to unloading is realized. A single power source can drive multiple vacuum suction cups to synchronously complete complex revolution and rotation movements, which greatly improves production efficiency and significantly reduces labor costs and labor intensity.

[0021] 2. Through gear meshing and synchronous belt transmission, the motion synchronization and positioning accuracy of each vacuum suction cup during station switching and posture adjustment are ensured. This mechanical synchronous transmission effectively avoids the slippage and error accumulation problems of traditional transmission methods, ensuring that each aluminum panel is in a precise and repeatable position and angle at the spraying station, thereby obtaining a uniform thickness and complete anti-stain coating, fundamentally improving the consistency and reliability of product quality.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 A stain-resistant aluminum panel surface treatment device includes a conveyor belt 1 for conveying the surface-treated aluminum panels. An electrostatic spray gun 2 and a feeding bin 3 are respectively installed on one side of the conveyor belt 1 via a support beam. A support side plate 4 is also installed on one side of the conveyor belt 1. A circulating material picking mechanism is installed on one side of the support side plate 4. The circulating material picking mechanism includes a vacuum suction cup 5. The vacuum suction cup 5 sequentially picks up the aluminum panels stacked in the feeding bin 3 and rotates to the side of the electrostatic spray gun 2 after circumferential revolution for electrostatic spraying. The sprayed aluminum panels are placed on the upper surface of the conveyor belt 1 for conveying.

[0029] To enable the vacuum suction cup 5 to rotate circumferentially and complete the cyclic loading and unloading of aluminum panels, the cyclic loading mechanism also includes a support shaft 6 rotatably connected to one side surface of the support side plate 4 via bearings. A support plate 7 is fixedly sleeved on the outer surface of the free end of the support shaft 6. The three extended support plates of the support plate 7 are rotatably connected to a linkage shaft 8 via bearings. The support shaft 6, support plate 7, and linkage shaft 8 form a rotary support platform, allowing the vacuum suction cup 5 to cyclically stop at the three workstations of the unloading bin 3, electrostatic spray gun 2, and conveyor belt 1. The rotation of the linkage shaft 8 causes the vacuum suction cup 5 to rotate, thereby allowing the vacuum suction cup 5 to rotate a certain angle on one side of the unloading bin 3, electrostatic spray gun 2, and conveyor belt 1, enabling it to complete the loading and unloading of aluminum panels.

[0030] To enable material picking and unloading, the circulating material picking mechanism also includes a rotating plate 9 fixedly sleeved on the outer surface of the free end of the linkage shaft 8. The free end of the rotating plate 9 is rotatably connected to a mounting shaft 10. The outer surface of the end of the mounting shaft 10 away from the support side plate 4 is fixedly connected to the outer surface of the frame of the vacuum suction cup 5 through a connecting pipe fixedly sleeved on its outer surface. By setting the rotating plate 9 at the free end of the linkage shaft 8 and rotatably connecting the mounting shaft 10 at the free end of the rotating plate 9, the vacuum suction cup 5 can be linked with the mounting shaft 10 through the connecting pipe. When the vacuum suction cup 5 revolves around different work positions, it can independently rotate a certain angle, flexibly adjusting the posture of the vacuum suction cup 5 so that it can adsorb aluminum single panels on one side. This solves the alignment deviation problem caused by fixed angle material picking and unloading, ensuring the accuracy of material picking, spraying, and unloading operations.

[0031] The circulating material handling mechanism also includes a synchronous wheel 11 that is fixedly sleeved on the outer surface of the linkage shaft 8 and the outer surface of the mounting shaft 10. The outer surfaces of the two synchronous wheels 11 are connected by a synchronous belt 12. The synchronous belt 12 and the synchronous wheel 11 transmit power through tooth meshing, which has the characteristic of zero slippage. This can strictly ensure that the speed ratio between the linkage shaft 8 and the mounting shaft 10 is constant. In the circulating material handling mechanism, this design makes the vacuum chuck 5 highly synchronized in the process of station switching during revolution and angle adjustment during rotation.

[0032] To achieve the rotation of the vacuum suction cup 5, the circulating material handling mechanism also includes a transmission shaft 13 rotatably connected to the surfaces of three extended support plates of the support plate 7 via bearings. The two ends of the transmission shaft 13 are respectively fixedly connected to a transmission gear 14 and a meshing gear 15. Another meshing gear 15 is fixedly sleeved on the outer surface of the linkage shaft 8. The two meshing gears 15 mesh, and when the transmission shaft 13 rotates, it drives the meshing gear 15 at one end to rotate. The meshing of the other meshing gear 15 enables the rotation of the linkage shaft 8. The rotation of the linkage shaft 8 then drives the vacuum suction cup 5 to rotate via the synchronous belt 12 and the synchronous pulley 11. In the circulating material handling mechanism, this design ensures that the position error of the vacuum suction cup 5 is minimal when switching work positions, avoiding positioning deviations caused by transmission slippage, and ensuring precise synchronization of material handling, spraying, and unloading actions.

[0033] The circulating material handling mechanism also includes a fixed gear 16 that is rotatably sleeved on the outer surface of the supporting shaft 6. Multiple transmission gears 14 mesh with the fixed gear 16. The fixed gear 16 serves as a reference component and transmits power synchronously to multiple transmission gears 14 through meshing, ensuring that the speed ratio of each transmission shaft 13 is strictly constant. During the circulating material handling process, this characteristic makes the position error of the vacuum chuck 5 extremely small when switching stations, avoiding positioning deviations caused by transmission slippage, and achieving precise synchronization of material handling, spraying, and unloading actions.

[0034] By setting up a circulating material handling mechanism consisting of a support shaft 6, a support plate 7, a linkage shaft 8, 14 sets of transmission gears, and 12 synchronous belt wheels, the fully automated continuous cycle operation of aluminum single panels from loading and spraying to unloading is realized. A single power source can drive multiple vacuum suction cups 5 to synchronously complete complex revolution and rotation movements, which greatly improves production efficiency and significantly reduces labor costs and labor intensity.

[0035] In order to realize the rotation of the support shaft 6, that is, to realize the revolution of the vacuum suction cup 5 driven by the support plate 7, a geared motor 17 is fixedly connected to one side surface of the support side plate 4. The output shaft of the geared motor 17 is fixedly connected to the drive gear 18, and the outer surface of the support shaft 6 is fixedly sleeved with the driven gear 19. The drive gear 18 and the driven gear 19 mesh, and the geared motor 17 realizes the rotation of the support shaft 6 through the meshing of the drive gear 18 and the driven gear 19, thereby completing the continuous picking and unloading of aluminum panels.

[0036] Through gear meshing and synchronous belt 12 transmission, the motion synchronization and positioning accuracy of each vacuum suction cup 5 during station switching and posture adjustment are ensured. This mechanical synchronous transmission effectively avoids the slippage and error accumulation problems of traditional transmission methods, ensuring that each aluminum panel is in a precise and repeatable position and angle at the spraying station, thereby obtaining a uniform thickness and complete anti-stain coating, fundamentally improving the consistency and reliability of product quality.

[0037] Working principle: In a specific embodiment of this invention, the reduction motor 17 starts, and the driving gear 18 on its output shaft drives the driven gear 19, which meshes with it, to rotate. The driven gear 19 is fixedly sleeved on the support shaft 6, thereby driving the support shaft 6 and the support plate 7 fixed at its front end to rotate together. This is the source of circumferential revolution power for the entire mechanism. The three extended support plates of the support plate 7 revolve accordingly, driving the entire material handling unit installed on it to make circular motion around the axis of the support shaft 6.

[0038] While the support plate 7 revolves, the fixed gear 16 remains engaged with multiple transmission gears 14. The revolving of the support plate 7 forces these transmission gears 14 to rotate around the fixed gear 16, thereby driving the transmission shaft 13 to rotate. The meshing gear 15 at one end of the transmission shaft 13 transmits power to another meshing gear 15 fixedly sleeved on the linkage shaft 8, thereby driving the linkage shaft 8 to rotate. The rotation of the linkage shaft 8 is precisely transmitted to another synchronous pulley 11 on the mounting shaft 10 through the synchronous pulley 11 and the synchronous belt 12 on it, so that the mounting shaft 10 rotates synchronously with the same speed and angle.

[0039] The rotation of the mounting shaft 10 ultimately drives the vacuum suction cup 5 to rotate via the connecting pipe, adjusting the angle of its adsorption panel. Through the aforementioned precision gear and synchronous belt 12 transmission system, the vacuum suction cup 5 is automatically controlled to rotate to a preset angle and posture as it revolves through different workstations. Its working cycle is as follows: When the vacuum suction cup 5 revolves above the unloading bin 3, its rotation is adjusted to a horizontal posture, vacuum adsorption is activated, and the top aluminum panel is grabbed. After grabbing the aluminum panel, the mechanism continues to revolve to below the electrostatic spray gun 2. At this time, the vacuum suction cup 5 rotates at an angle so that the surface of the aluminum panel faces the spray gun in the best posture, ensuring uniform spraying. After the spraying is completed, the mechanism revolves above the conveyor belt 1, the vacuum suction cup 5 adjusts its posture again, releases the vacuum, and places the sprayed aluminum panel stably on the conveyor belt 1. The three vacuum suction cups 5 operate synchronously on the three extended support plates of the support plate 7, so that the three processes of picking up, spraying, and unloading are carried out simultaneously, forming an efficient continuous production cycle.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
