[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Example: Figure 1-5 As shown, the utility model is an industrial spraying robot, comprising a driving motor 1, a driving box 2 fixedly connected to the bottom of the driving motor 1, a slide rail 3 is arranged near one end of the driving box 2, a lead screw 4 is arranged inside the driving box 2, a slider 5 is slidably connected to the surface of the slide rail 3, a movable plate 6 is bolted to the top of the slider 5, an upper flange 7 is arranged at the center position of the movable plate 6, the upper flange 7, a turntable 8 is fixedly connected to the top of the upper flange 7, a base 9 is arranged on the top of the turntable 8, a material cylinder 10 is fixedly connected to the surface of the base 9, a large arm 11 is arranged on one side of the base 9, a small arm 13 is arranged on one side of the large arm 11, and a pneumatic pump 12 is fixedly connected to one end of the small arm 13, and a material delivery pipe 14 is provided on the base 9, the large arm 11 and the small arm 13.

[0025] Among them, the output end of the drive motor 1 is fixedly connected to the transmission shaft 101, and one end of the transmission shaft 101 is in the shape of a bevel gear. This design can realize cross or right-angle transmission between the two shafts, adapting to different spatial layouts and transmission requirements. The bevel gear transmission has the characteristics of strong load-bearing capacity, smooth transmission and low noise, which can effectively ensure the stability of equipment operation.

[0026] Among them, one end of the screw 4 is in the shape of a bevel gear and is meshed with one end of the transmission shaft 101. The bevel gear can realize right-angle or cross transmission between the two shafts, so the linear motion of the drive motor 1 can be converted into the rotational motion of the screw 4, or vice versa, to meet different power transmission requirements, and is particularly suitable for occasions that require vertical or angular position adjustment.

[0027] Among them, the bottom of the upper flange 7 is bolted to the lower flange 701, and a moving block is fixedly welded to the bottom of the lower flange 701. The upper flange 7 is connected to the lower flange 701 by bolts, which can ensure that the connection between the two is strong and stable, and can withstand large axial and radial forces to prevent loosening due to vibration or impact.

[0028] Among them, the rotating shaft 801 is clamped inside the turntable 8, and the rotating shaft 801 is provided with an annular tooth 802, which can ensure that the connection between the rotating shaft 801 and the turntable 8 is tight and the rotation is smooth, reduce vibration and noise caused by looseness, and improve the stability of the overall transmission.

[0029] Among them, an upper sealing gasket 803 is provided on the top of the turntable 8, and a lower sealing gasket 804 is provided on the bottom of the turntable 8. The design of the upper sealing gasket 803 and the lower sealing gasket 804 can effectively prevent dust, moisture or other impurities from entering the turntable 8, and can also prevent the lubricant or medium in the turntable 8 from leaking out, thereby ensuring the cleanliness and safety of the equipment during operation.

[0030] Among them, the ring gear 802 is internally meshed with a driving gear 805, and a driving shaft 806 is fixedly welded to the surface of the driving gear 805. One end of the driving shaft 806 is fixedly connected to a servo motor 807. This integrated design enhances the connection strength between the driving gear 805 and the driving shaft 806, and effectively prevents equipment failure caused by loose connection under high-speed or high-torque operation conditions.

[0031] Working principle: When in use, first, check whether the connections of various parts of the spray robot are firm, fill the material to be sprayed in the material cylinder 10, and ensure that the feed pipe 14 is unobstructed, turn on the power and start the control system, preset the spraying path and parameters, including the rotation angle of the turntable 8, the moving distance of the slider 5 on the slide rail 3 and the spraying speed, etc., start the drive motor 1, and its output end transmits power to the screw 4 through the fixedly connected bevel gear-shaped transmission shaft 101. The screw 4 engages and rotates with the transmission shaft 101 to realize linear motion conversion, and the screw 4 drives the slider 5 to perform precise linear reciprocating motion along the slide rail 3. The movable plate 6 bolted to the top of the slider 5 moves to the predetermined position. When the movable plate 6 moves, it drives the turntable 8 to adjust its position in the horizontal direction. The servo motor 807 drives the driving gear 805 to rotate through the driving shaft 806. Since the driving gear 805 is engaged with the annular gear 802 inside the rotating shaft 801, the precise rotation of the turntable 8 is achieved. Under the coordinated action of the turntable 8 and the movable plate 6, the base 9 is positioned in three dimensions as the turntable 8 rotates and the slider 5 moves. The paint in the material cylinder 10 is transported to the pneumatic pump 12 on the forearm 13 through the feed pipe 14. The pneumatic pump 12 drives the nozzle according to the preset program to perform multi-angle and uniform spraying operations on the workpiece surface.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.
