Embodiment 1

[0036] As the basic implementation of the application, the application includes an experimental device for measuring the fog cone angle based on images, including a camera 1, a light source 2, a spray gun 3 and a turntable 4, and the camera 1 and the light source 2 are connected to the turntable 4 through a connecting rod 6, respectively. connected, and the light from the light source 2 is parallel to the axis of the lens of the camera 1 . The spray gun 3 is located above the turntable 4, the nozzle of the spray gun 3 coincides with the axis of the turntable 4, and the turntable 4 rotates clockwise or counterclockwise along the axis.

[0037] The spray gun 3 can be a spray gun 3 in other areas than this experimental device, and has no connection relationship with the turntable 4, camera 1 and light source 2. When in use, keep the nozzle of the spray gun 3 coincident with the axis of the turntable 4.

[0038] Or the spray gun 3 can also be fixed on a device at the rest position...

Embodiment 2

[0040] As a preferred embodiment of the application, the application includes an image-based experimental device for measuring the fog cone angle, including a camera 1, a light source 2, a spray gun 3, a turntable 4, and a drive turntable 4 that rotates clockwise or counterclockwise along the axis. Drive 5. The driving member 5 can be a stepping motor.

[0041] The light source 2 can be a spotlight. The camera 1 and the light source 2 are connected to the turntable 4 through the connecting rod 6 respectively. Can be flange mounted. The light from the light source 2 is parallel to the axis of the lens of the camera 1 , and the degree of parallelism can only be visually parallel.

[0042] The spray gun 3 can be suspended above the turntable 4 through a boom, and the nozzle of the spray gun 3 coincides with the axis of the turntable 4 .

[0043] The diameter of the turntable 4 is 0.8m, and the edge position of the turntable 4 is provided with an angle scale.

[0044] When in ...

Embodiment 3

[0046] As another preferred embodiment of the present application, the present application includes an experimental device for measuring the fog cone angle based on images, including a camera 1 , a light source 2 , a spray gun 3 and a turntable 4 . The camera 1 and the light source 2 are respectively connected to the turntable 4 through the connecting rod 6, and the light of the light source 2 is parallel to the axis of the lens of the camera 1; the turntable 4 rotates clockwise or counterclockwise along the axis; the spray gun 3 is located at Above the turntable 4, the nozzle of the spray gun 3 coincides with the axis of the turntable 4, and the spray gun 3 moves up and down in the axial direction of the turntable 4 through the mechanical arm 7 or the boom.

[0047] The diameter of the turntable 4 is 1.3m.

[0048] The connecting rod 6 is a lifting rod.

[0049] The bottom of the experimental device is provided with a silent wheel, and brake pads are installed on the surface...

Abstract

The invention relates to the technical field of spraying processes, in particular to an experimental device for measuring a mist cone angle based on an image. The experimental device comprises a camera, a light source, a spray gun and a turntable, wherein the camera and the light source are connected with the turntable through connecting rods respectively; light rays of the light source are parallel to the axis of a lens of the camera; the spray gun is positioned above the turntable; a nozzle of the spray gun coincides with the axis of the turntable; and the turntable rotates clockwise or counterclockwise along the axis. Through the adoption of the experimental device, the problem of inconvenience in moving due to the large structure of the device can be effectively solved, and the operation becomes easier.

Description

technical field [0001] The present application relates to the technical field of spraying technology, in particular to an experimental device for measuring fog cone angle based on images. Background technique [0002] In the field of spraying process research, the measurement of spraying shape has important practical significance for spraying process research. The spray shape refers to the shape of the coating formed after the paint is cured after the paint is sprayed on the surface of the workpiece for a certain period of time under the static state of the spray gun. The spraying shape is often elliptical, and the length of its major axis represents the spraying width, which is the basis for planning the spraying trajectory and designing the overlap distance; the length of the minor axis is often easily ignored, but the length of the minor axis is also useful for establishing the distribution model of the sprayed coating thickness. important meaning. [0003] For the meas...
