Description

[0002] The automatic passivation equipment for magnesium-aluminum alloys is used to automate the surface treatment of magnesium-aluminum alloys. Passivation is a surface treatment method that improves the corrosion resistance and wear resistance of metals by forming a thin film of oxides or other compounds on the surface of magnesium-aluminum alloys. The automatic passivation equipment for magnesium-aluminum alloys can uniformly spray the passivation liquid onto the surface of magnesium-aluminum alloys. The automatic passivation equipment for magnesium-aluminum alloys typically includes components such as spray heads, nozzles, and spray control systems, which can control parameters such as the flow rate of the spray liquid, the spray direction, and the spray speed.

[0003] Existing automated passivation equipment for magnesium-aluminum alloys partially relies on manual material feeding and sorting operations, which cannot accurately control the separation of individual sheets. Operators often experience simultaneous feeding of two sheets or material jamming when manually separating stacked magnesium-aluminum alloy sheets for extended periods of time, leading to frequent production line interruptions. Furthermore, the rhythm of manual sheet placement is unstable and difficult to synchronize with subsequent processes, affecting overall production efficiency. To address these issues, an automated passivation equipment for magnesium-aluminum alloys is provided. Utility Model Content

[0007] A single-sided passivation mechanism is provided, with two sets of such mechanisms arranged on the side of the automatic feeding mechanism. The single-sided passivation mechanism is used to uniformly spray a passivation liquid onto one side of the magnesium-aluminum alloy sheet.

[0008] An automatic flipping mechanism is located between two sets of single-sided passivation mechanisms. The automatic flipping mechanism is used to flip the magnesium-aluminum alloy sheet after single-sided passivation treatment.

[0011] As a further improvement of this utility model: the distance between the bottom of the discharge baffle and the top of the support platform is slightly greater than the thickness of one set of magnesium-aluminum alloy plates, but less than the thickness of two sets of magnesium-aluminum alloy plates, allowing only one set of magnesium-aluminum alloy plates to pass through at the same time.

[0012] As a further embodiment of this utility model: the connecting column portion of the plate pusher is adapted to the guide groove of the slider, and the height of the pusher portion of the plate pusher above the support platform is adapted to the thickness of a set of magnesium-aluminum alloy plates.

[0028] Reference Figures 1 to 6 In this embodiment of the present invention, an automatic passivation device for magnesium-aluminum alloys includes:

[0029] An automatic feeding mechanism 1 is used to intermittently push magnesium-aluminum alloy sheets for feeding. The automatic feeding mechanism 1 includes a support platform 11, a sheet limiting plate 12 fixedly connected above the support platform 11, and a discharge baffle 13 fixedly connected to the inner side of the sheet limiting plate 12. The distance between the bottom of the discharge baffle 13 and the top of the support platform 11 is slightly greater than the thickness of one set of magnesium-aluminum alloy sheets but less than the thickness of two sets of magnesium-aluminum alloy sheets, allowing only one set of magnesium-aluminum alloy sheets to pass through at the same time. A slider guide groove 14 is provided above the support platform 11, and top block turning through holes 15 are provided at both ends of the slider guide groove 14 above the support platform 11. A rotating shaft bracket 16 is fixedly connected below the sheet surface of the support platform 11, and the side of the rotating shaft bracket 16 is rotatably connected via a rotating shaft. A support turntable 17 is connected to the support platform 11. A first drive motor 19 is fixedly connected to the bottom of the plate surface. A transmission belt 18 is provided on the outside of the support turntable 17. A plate push block 110 is fixedly connected to the outside of the transmission belt 18. The connecting column part of the plate push block 110 is adapted to the slider guide groove 14. The height of the push plate part of the plate push block 110 above the plate surface of the support platform 11 is adapted to the thickness of a set of magnesium-aluminum alloy plates. There are four sets of rotating shaft brackets 16. A set of support turntables 17 is provided between each two sets of rotating shaft brackets 16. The outside of the two sets of support turntables 17 is connected to the transmission belt 18. The rotating shaft of the first drive motor 19 passes through the rotating shaft bracket 16 and is fixedly connected to the rotating shaft of one of the sets of support turntables 17.

[0030] Single-sided passivation mechanism 2, two sets of single-sided passivation mechanism 2 are set on the side of automatic feeding mechanism 1. Single-sided passivation mechanism 2 is used to uniformly spray one side of magnesium-aluminum alloy sheet with passivation liquid.

[0031] Automatic flipping mechanism 3 is located between two sets of single-sided passivation mechanisms 2. Automatic flipping mechanism 3 is used to flip the magnesium-aluminum alloy sheet after single-sided passivation treatment.

[0032] Using the above scheme: the first drive motor 19 drives the support turntable 17 to rotate, and drives the plate pusher 110 to move along the slider guide groove 14 through the transmission belt 18. When the plate pusher 110 moves above the support platform 11, its push plate part pushes the bottom magnesium-aluminum alloy plate forward. Due to the gap between the discharge baffle 13 and the support platform 11, only a single layer of plate is allowed to pass through at a time. After the plate pusher 110 passes through the top block turning through hole 15, it rotates downward to complete the intermittent pushing cycle.

[0033] The single-sided passivation mechanism 2 includes a support platform 21, a conveyor belt 22 is provided on the inner side above the support platform 21, and a passivation liquid spraying machine 23 is fixedly connected above the support platform 21. The passivation liquid spraying machine 23 is equipped with multiple sets of passivation liquid atomizing nozzles and is connected to an external passivation liquid pipeline through a hose.

[0034] Using the above scheme: Conveyor belt 22 transports magnesium-aluminum alloy sheets from automatic feeding mechanism 1, and passivation liquid spraying machine 23 uniformly sprays the surface of the sheet using multiple sets of atomizing nozzles. The sheet moves at a constant speed during the conveying process to ensure that the passivation liquid coating thickness is consistent.

[0035] The automatic flipping mechanism 3 includes a first bracket 31, a second bracket 32 ​​and a third bracket 33 on the side of the first bracket 31, a butterfly support plate 34 rotatably connected between the first bracket 31 and the second bracket 32, and plate positioning slots 35 adapted to the size of the magnesium-aluminum alloy single plate on both sides of the butterfly support plate 34. An elliptical rotating plate 36 is rotatably connected to the side of the second bracket 32, and the rotating shaft of the elliptical rotating plate 36 passes through the second bracket 32 ​​and is fixedly connected to the plate positioning slots 35. A second drive motor 37 is fixedly connected to the side of the third bracket 33 away from the second bracket 32, and a circular turntable 38 is rotatably connected to the side of the third bracket 33 close to the second bracket 32. The rotating shaft of the second drive motor 37 passes through the third bracket 33 and is fixedly connected to the circular turntable 38. Several sets of push columns 39 are fixedly connected in a ring at equal intervals on the side of the circular turntable 38 close to the second bracket 32. An arc-shaped push groove 310 adapted to the push column 39 is opened on the side of the elliptical rotating plate 36.

[0036] Using the above scheme: the second drive motor 37 drives the rotary table 38 to rotate, and the push column 39 sequentially engages the arc-shaped push groove 310 to push the elliptical rotating plate 36 to rotate. The elliptical rotating plate 36 drives the butterfly support plate 34 to rotate 180 degrees through the rotating shaft, so that the magnesium-aluminum alloy plate in the plate positioning groove 35 is flipped. After the magnesium-aluminum alloy plate comes into contact with the conveyor belt 22 of the next set of single-sided passivation mechanisms 2, it is moved away.

[0037] The working principle of this utility model is as follows: First, the first drive motor 19 of the automatic feeding mechanism 1 drives the support turntable 17 to rotate, and drives the plate pusher 110 to circulate along the slider guide groove 14 through the transmission belt 18. When the plate pusher 110 rises to the surface of the support platform 11, its push plate part pushes the bottom magnesium-aluminum alloy plate forward. Under the limiting action of the discharge baffle 13, the precise separation and intermittent conveying of a single plate are realized, and the automatic feeding process of the plate is completed.

[0038] Subsequently, the pushed magnesium-aluminum alloy sheet enters the first single-sided passivation mechanism 2, and is conveyed at a constant speed by the conveyor belt 22 to the bottom of the passivation liquid spraying machine 23. Multiple sets of atomizing nozzles uniformly spray the upper surface of the sheet to form a complete passivation liquid protective layer. The sprayed sheet continues to be conveyed to the automatic flipping mechanism 3, and is received by the sheet positioning slot 35 of the butterfly support plate 34.

[0039] In the automatic flipping mechanism 3, the second drive motor 37 drives the rotary table 38 to rotate, and the push column 39 cooperates with the arc-shaped push groove 310 to drive the elliptical rotating plate 36 to rotate, so that the butterfly support plate 34 can be flipped 180 degrees. The flipped plate falls into the second set of single-sided passivation mechanism 2, is conveyed by the conveyor belt 22 and undergoes passivation treatment on the other side, and finally outputs the finished plate with double-sided passivation. The whole process realizes the continuous production of magnesium-aluminum alloy plates with automatic feeding, double-sided passivation and automatic flipping.

[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.
