Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and in particular relates to an online film thickness detection device used on a powder spraying line. Background Art

[0002] As we all know, in the field of industrial manufacturing and production, powder spraying is also an important production and processing link. At the same time, with the wider application of powder spraying technology, the quality requirements for spraying are also getting higher and higher. The types of equipment used for spraying are also increasing. At the same time, the spraying process is also being refined. Specifically, the film thickness detection device used for online detection of the thickness of the sprayed powder film is also one of the important spraying equipment. The film thickness detection instrument mainly works outside the powder spraying room. After the workpiece leaves the powder spraying room and before entering the curing furnace, the film thickness of the uncured workpiece on the sprayed surface must be detected. In conventional film thickness detection instruments, the size is large and the detection range is not flexible enough, which leads to the detection The measurement range is narrow, so the existing film thickness detection instrument is needed. When performing film thickness detection, especially when facing the detection of larger special-shaped workpieces, because the sprayed surface of the special-shaped workpiece that needs to be detected is a curved surface or convex surface or other irregular spraying surface, the sensing range of the sensing part should be wide, and it can perform sensing detection in a larger range at any time with the cooperation of smart mobile devices. Therefore, a film thickness detection device with good accompanying sensing detection flexibility is needed. The film thickness detection instrument can perform multi-faceted sensing detection on any sprayed surface or special-shaped sprayed surface of large special-shaped workpieces at any time. The sensing detection range is wider before the sprayed surface is solidified, and the spraying efficiency is improved at the same time, and a film thickness detection device for spraying is used.

[0022] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted," "one end," "the other end," and similar expressions used in this utility model are for illustrative purposes only.

[0023] like Figure 1-4The present embodiment provides a film thickness detection device for spraying, including a film thickness detection mechanism and a mobile connecting mechanism. The film thickness detection mechanism is movably connected to the mobile connecting mechanism. When the work is implemented, it is installed and connected to a mobile installation body or a robot. The film thickness detection mechanism includes a film thickness detection instrument main body 1 and a detection connection assembly 2. The film thickness detection instrument main body 1 is provided with a sensing part 3. The film thickness detection instrument main body 1 mainly works outside the powder spraying room. The sensing part 3 is used to form a sensing range outside the powder spraying room near the powder spraying room outlet end on the film thickness detection instrument main body 1. Specifically, the workpiece to be tested for film thickness must leave the powder spraying room after spraying and then enter the curing furnace. Therefore, after leaving the powder spraying room and before entering the curing furnace, the uncured spray film must be detected. The sensing part 3 provided on the film thickness detection instrument main body 1 is adjusted according to the sensing range on the mobile installation body. The chain is installed in the direction of the chain, the sensing part 3 is close to the outlet end of the powder room, the mobile connecting mechanism includes a first connecting component 4 and a second connecting component 5, the first connecting component 4 is rotatably connected to the second connecting component 5, the detection connecting component 2 is connected to the first connecting component 4, the first connecting component 4 is used to drive the sensing part 3 on the main body 1 of the film thickness detection instrument to perform mobile detection work in the first direction, and the second connecting component 5 drives the sensing part 3 on the main body 1 of the film thickness detection instrument to perform mobile detection work in the second direction. The set first connecting component 4 will drive the film thickness detection instrument to rotate up and down or left and right in a small range based on the horizontal line of the first connecting component 4. The first connecting component 4 can rotate up or down in a large range on the second connecting component 5, thereby carrying the film thickness detection instrument to move in a large range of directions.
