Description

Technical Field

[0001] The utility model belongs to fluorescence detection equipment, in particular to an electrostatic spraying device for fluorescent penetrant. Background Art

[0002] Fluorescent penetrant is widely used in the detection of surface defects on various metals, non-metals, ceramics, and other materials. It is particularly suitable for inspecting the surfaces of large quantities of workpieces, effectively detecting defects such as cracks and sand holes. Compared to traditional immersion penetrant methods, this method utilizes an automatic electrostatic spraying method to apply the fluorescent penetrant to the workpiece surface, where penetrant removal is difficult on cavities and porous workpieces. This method prevents the fluorescent penetrant from entering deep holes and is easy to clean. This method also reduces the user's consumption of penetrant consumables and effectively controls inspection costs.

[0003] However, existing electrostatic spraying equipment has several drawbacks. First, as the sprayer electrostatically coats the workpiece, fluorescent penetrant drifts into the air within the spray chamber. As the spraying process progresses, the concentration of fluorescent penetrant in the air increases, and workers can inhale this air, posing a safety hazard. Second, while testing companies currently primarily utilize suspension and roller conveyors for material transport, existing electrostatic spraying equipment cannot accommodate both.

DETAILED DESCRIPTION

[0019] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0020] See attached Figures 1 to 3 , a fluorescent penetrant electrostatic spraying device, comprising: a spraying chamber 100, a feed window 110 formed on both sides of the spraying chamber 100, a roller transmission device 200 arranged in the spraying chamber 100 and extending to both sides of the feed window, a feed gap 120 formed on the spraying chamber 100 and extending to both sides of the feed window to allow the suspension rope of the suspension device to pass through 100, a rotating mechanism 300 arranged on the roller transmission device 200 and suitable for adjusting the position of the workpiece to be inspected, and an electrostatic spraying device 400 arranged on one side of the roller transmission device 200 and suitable for spraying fluorescent penetrant.

[0021] In this embodiment, a feed slot 120 allows the passage of a suspension rope for a suspended workpiece, enabling loading of the suspended workpiece. A built-in roller conveyor 200 accommodates roller conveying, achieving compatibility with various transport methods. Furthermore, a rotating mechanism 300 within the spray chamber 100 adjusts the position of the workpiece to be inspected, cooperating with an electrostatic sprayer 400 to ensure full coverage. The electrostatic sprayer 400 precisely applies the fluorescent penetrant.

[0022] In a further embodiment, an exhaust fan is installed outside the spray booth 100, and the exhaust fan's air inlet is connected to the interior of the spray booth 100. Air containing the permeate is continuously discharged through the air inlet connected to the interior of the spray booth 100, significantly reducing health risks for operators. Furthermore, for the safety of manual electrostatic sprayers, a control room 130 is located on one side of the spray booth 100. This control room 130 houses a control unit, which is signal-connected to the roller transmission device 200, the rotating mechanism 300, the electrostatic spraying equipment 400, and the exhaust fan, enabling automated spraying of the entire electrostatic spraying equipment 400.

[0023] In further embodiments, see the attached Figure 3 The rotating mechanism 300 includes: a base 310 disposed at the bottom of the roller conveyor 200; a lifting device 320 disposed on the base 310; a lifting mounting base 330 located at the output end of the lifting device 320; a driving source 340 disposed on the lifting mounting base 330; and a turntable 350 drivingly connected to the driving source 340 and extending to the upper portion of the roller conveyor 200 so as to be inserted into the gaps formed between the rollers of the roller conveyor 200. The lifting device 320 is a lifting cylinder or an electric lift. It is understood that a circular hole is provided in the roller conveyor 200, allowing the turntable 350 to pass through the roller conveyor 200. The turntable 350 is then raised by the lifting device 320 to clear the roller conveyor 200. The drive source 340 then rotates the turntable 350 via a transmission structure (such as gears, belts, or chains) to adjust the position of the workpiece to be inspected. The turntable 350 also includes an annular main body 351 and multiple support portions 352 evenly distributed around the main body 351. This ensures structural strength while ensuring uniform support and rotation of the workpiece placed thereon, thereby achieving all-round coverage of the penetrant during the electrostatic spraying process.

[0024] In a further embodiment, the roller transmission device 200 includes a plurality of active roller groups 210 spaced apart by predetermined gaps and connected to a transmission motor 230, and a driven roller group 220 disposed within the body 351. This means that the workpiece to be inspected or the container holding the workpiece to be inspected must be larger than the body 351, with at least some area of ​​the active roller group 210 connected to achieve roller transmission.

[0025] In a further embodiment, the electrostatic spraying apparatus 400 includes a six-axis robot 410 and a fluorescent penetrant nozzle assembly 420 disposed at the output end of the six-axis robot 410. The six-axis robot 410, with its six degrees of freedom, enables a wide range of motion and highly precise positioning control in three-dimensional space, thereby improving the accuracy and efficiency of electrostatic spraying of the fluorescent penetrant.

[0026] In a further embodiment, a dust curtain is hung on the feed window 110. This can reduce the entry of external pollutants into the spray booth 100 and help limit the excessive escape of air containing the penetrant, thereby improving the working environment and enhancing the safety level.

[0027] To facilitate understanding of the technical solution of the electrostatic spraying device for fluorescent penetrants, a brief description of its operating principle is provided: During the spraying process, the workpiece to be inspected can be suspended by a suspension device, with the suspension rope passing through the feed slit 120 and transferred to the rotating mechanism 300 within the spray chamber 100, or it can be transferred to the rotating mechanism 300 within the spray chamber 100 using a roller transmission device 200. The six-axis robot 410 then moves across the workpiece surface along a pre-programmed path. Under the influence of a high-voltage electrostatic field, the nozzle atomizes and carries the fluorescent penetrant, causing the charged paint particles to be evenly and firmly adsorbed on the workpiece surface, forming a fine and uniform fluorescent penetrant layer. The entire spraying process is centrally managed by a control unit located in the control room 130, achieving highly automated and intelligent operation.

[0028] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.
