Technical Field
[0001] This utility model relates to the field of coating and spraying technology, and in particular to a device for preventing electro-erosion coating of wind turbine generator bearings. Background Technology
[0002] Coating spraying is a process in which coatings (such as paint, powder, ceramics, metals, etc.) are atomized or dispersed into tiny particles using specific equipment and then applied to the surface of a workpiece via high-speed spraying or coating to form a solid coating with protective, decorative, and functional enhancement properties (such as insulation, wear resistance, and corrosion resistance). Its core principle is to use physical or chemical means to bond the coating particles to the substrate surface. By controlling spraying parameters (pressure, distance, angle, etc.), the coating thickness, uniformity, and performance can be precisely controlled. It is widely used in machinery manufacturing, aerospace, automotive, and electronics industries.
[0003] In the manufacturing of wind turbine generator bearings, the surface is often treated with coating spraying equipment to spray an anti-electro-erosion coating to reduce the influence of electromagnetic fields on the bearing. However, the existing bearing spraying equipment requires manual adjustment of the nozzle angle and other parameters, which places high demands on the operators and is also prone to errors, resulting in poor uniformity of the coating during spraying.
[0004] Therefore, we propose a wind turbine generator bearing anti-electrolytic corrosion coating device to solve the above problems. Utility Model Content

A flipping groove is opened on one side of the mechanical arm, and a flipping base is rotatably installed on the inner side of the flipping groove. A spraying hole is opened on the outer side of the flipping base, and a spraying column is fixedly installed on the inner side of the spraying hole. A spraying mechanism is provided on the spraying column.
[0007] Specifically, a turntable is rotatably mounted on the top of the spraying station, and a turntable chamber is opened inside the spraying station.

[0008] Specifically, a wind turbine generator bearing is placed on the top of the turntable. The turntable can drive the wind turbine generator bearing to rotate at a uniform speed. The uniform rotation speed can make the residence time of each part of the wind turbine generator bearing in the spraying area consistent, which is conducive to forming a coating with uniform thickness.
[0009] Specifically, the fixed base has a drive slot inside, and an orientation servo motor is fixedly installed on the inner side of the drive slot.

A cylinder is fixedly installed on the outer side of the spray column, and the piston end of the cylinder is fixedly connected to the inner grooved ring. A rotating base is rotatably installed on one end of the spray column. A motor slot is formed inside the spray column, and a rotating servo motor is fixedly installed on the inner side of the motor slot. The output shaft of the rotating servo motor is fixedly connected to the rotating base, and the rotating base can be rotated by the rotating servo motor.
[0012] Specifically, the spraying mechanism includes a core shaft, a ball joint, and a spraying base. A rotating hole is provided on one side of the rotating base, and the core shaft is rotatably installed inside the rotating hole. The ball joint and the spraying base are respectively fixedly installed at both ends of the core shaft. The ball end of the ball joint is slidably installed in the inner groove. A pneumatic atomizing nozzle is fixedly installed on one side of the spraying base. By flipping or rotating the spraying base, the pneumatic atomizing nozzle can be driven to make fine adjustments to its tilt angle and orientation.
[0013] Specifically, a spray box is fixedly installed on one side of the spraying station, and a paint pipe is fixedly installed on the top of the spray box. The other end of the paint pipe is connected to the flange of the pneumatic atomizing nozzle, so that the coating particles can be transported to the pneumatic atomizing nozzle through the paint pipe via the spray box.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the spraying mechanism can adapt to wind turbine generator bearings of different sizes and shapes, and can perform point spraying on complex curved surfaces such as the inner ring, outer ring, and rolling elements of the wind turbine generator bearing, which increases the applicability of the equipment, reduces manual adjustment errors, improves coating uniformity, and increases the practicality of the equipment.

[0026] In this embodiment, an inner groove ring 12 is slidably installed on the outer side of the spray column 10, and an inner groove is formed on the inner side of the inner groove ring 12. A cylinder 11 is fixedly installed on the outer side of the spray column 10, and the piston end of the cylinder 11 is fixedly connected to the inner groove ring 12. A rotating base 14 is rotatably installed on one end of the spray column 10.

The output shaft of the rotating servo motor 13 is fixedly connected to the rotating base 14, and the rotating base 14 can be rotated by the rotating servo motor 13.
[0027] In this embodiment, the spraying mechanism includes a core shaft 15, a ball head rod 16, and a spraying base 17. A rotating hole is provided on one side of the rotating base 14.

[0028] In this embodiment, a spray box 20 is fixedly installed on one side of the spraying station 1, and a paint pipe 19 is fixedly installed on the top of the spray box 20.

[0029] Working Principle: When spraying the anti-electro-erosion coating on the wind turbine generator bearing 4, the operator places the wind turbine generator bearing 4 on the turntable 2, and then adjusts the robotic arm 7. First, the orientation servo motor 6 is started to adjust the orientation of the robotic arm 7, and then the tilting servo motor 8 is started. The tilting servo motor 8 drives the tilting base 9 to rotate, and the rotation of the tilting base 9 drives the spraying mechanism to tilt, so that the pneumatic atomizing nozzle 18 is aligned with the wind turbine generator bearing 4. The operator then makes fine adjustments to the pneumatic atomizing nozzle 18 through the spraying mechanism. The cylinder 11 is started to drive the inner groove ring 12 to slide on the spraying column 10. The sliding of the inner groove ring 12 drives the inner groove on the inner side to move. The movement of the inner groove drives the ball end of the ball head rod 16 to move. The movement of the ball end drives the ball head rod 16 to rotate around the core shaft 15 as the center. While the ball head rod 16 is rotating, it also drives the core shaft 15 and the spraying base 17 to rotate. The servo motor 13 starts and drives the rotating base 14 to rotate. The rotation of the rotating base 14 drives the core shaft 15 on its inner side, together with the ball head rod 16 and the spraying base 17, to rotate around the servo motor 13. The rotation or flipping of the spraying base 17 can drive the pneumatic atomizing nozzle 18 to make fine adjustments to its tilt angle and orientation, which can effectively improve the spraying accuracy. The turntable servo motor 3 starts and drives the turntable 2 to rotate. The rotation of the turntable 2 drives the fan generator bearing 4 placed on it to rotate at a uniform speed. At the same time, the spraying box 20 delivers coating particles to the pneumatic atomizing nozzle 18 through the paint pipe 19 to spray the fan generator bearing 4. The uniform rotation can make the residence time of each part of the fan generator bearing 4 in the spraying area consistent. With the spraying of the spraying equipment, a coating of uniform thickness is formed, preventing uneven thickness of the anti-electro-erosion coating, which could lead to localized puncture.
[0030] The technological advancements of this invention compared to existing technologies are: it can adapt to wind turbine generator bearings 4 of different sizes and shapes, and can perform targeted spraying on complex curved surfaces such as the inner ring, outer ring, and rolling elements of the wind turbine generator bearing 4, increasing the applicability of the equipment, reducing manual adjustment errors, improving coating uniformity, and increasing the practicality of the equipment.
