Among them, for the test of some physical properties of paint, such as water permeability test, water resistance test and elongation at break test, the test content of different manufacturers varies according to the different fields in which their own paints are used. During the test, the paint needs to be brushed onto the corresponding template with a brush, and then dried by air drying or baking. Then, different testing equipment is used to test the paint on the template according to different test contents.

[0003] However, in the prior art, manual coating is often used when applying paint to the template. This method is more suitable for small-batch testing.

[0031] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] Example 1

[0033] Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 In one embodiment of the present invention, the paint is automatically applied to the template through relevant devices, and the bucket used to hold the paint is cleaned at the same time, reducing the burden on inspectors and the time consumed by cleaning.

[0034] A coating application device includes a shell 1 as a mounting carrier, a control cabinet 2 mounted on the shell 1, a coating mechanism 3 for automatically applying paint to a template provided within the shell 1, and the control cabinet 2 for controlling the movement of a related transmission mechanism within the coating mechanism 3. The coating mechanism 3 automatically applies the paint to the template and simultaneously cleans the paint bucket, thereby significantly saving the time of inspectors.

[0035] The coating mechanism 3 includes an electric track assembly 31 horizontally arranged in the shell 1, and two sliding seats 32 are installed on the electric track assembly 31 for transmission. A rotatable paint bucket assembly 33 is installed between the two sliding seats 32 for sliding up and down. When it is necessary to apply paint, a certain amount of paint is poured into the barrel-shaped container of the paint bucket assembly 33, or the finished paint bucket is directly placed on the paint bucket assembly 33 and fixed. A lifting assembly 34 is installed on the top of the shell 1, and a stirring assembly 35 for stirring the paint in the paint bucket assembly 33 is installed on the lifting assembly 34. When the paint is poured into the cavity of the paint bucket assembly 33, the electric track assembly 31 drives the two sliding seats 32 to make the paint bucket 33 move upward and downward. The material barrel assembly 33 moves to the bottom of the stirring assembly 35. At this time, the lifting assembly 34 drives the stirring assembly 35 to descend and stir the paint evenly. The lower part of the lifting assembly 34 is vertically slidably installed with a horizontal track assembly 36. A vertical track 37 is provided in the shell 1 that is slidably connected to the horizontal track assembly 36. The vertical track 37 is used to limit the trajectory of the horizontal track assembly 36 when sliding to avoid trajectory deviation. The paint barrel assembly 33 is slidably set on the horizontal track assembly 36. The lifting assembly 34 drives the horizontal track assembly 36 to move up and down along the vertical track 37, thereby driving the paint barrel assembly 33 slidingly set on the horizontal track assembly 36 to move up and down. The bottom of the component 31 is provided with a rotating assembly 38 for driving the horizontal track assembly 36 to rotate, and the lifting assembly 34 is provided with a driving assembly 39 for driving the paint bucket assembly 33 to rotate. A cleaning box 40 is installed at the bottom of the shell 1, and a guide plate 41 for receiving excess paint in the paint bucket assembly 33 is provided on the side of the shell 1. When it is necessary to pour out the excess paint in the barrel-shaped container of the paint bucket assembly 33 and clean it, the paint bucket assembly 33 is lowered by the lifting assembly 34. During the lowering process, the horizontal track assembly 36 is first rotated by the rotating assembly 38 and the paint bucket assembly 33 is driven to rotate, so that the excess paint in the cavity of the paint bucket assembly 33 is poured into the guide plate 41. The paint bucket assembly 33 is placed on the guide plate 41 and guided to other containers for collection and centralized processing. The paint bucket assembly 33 is then inverted in the cleaning liquid in the cleaning tank 40. At this time, the barrel-shaped cavity of the paint bucket assembly 33 is driven to rotate by the rotating assembly 38, so that the centrifugal force during the rotation of the paint bucket assembly 33 is used to complete the cleaning of the cavity. Subsequently, as the lifting assembly 34 drives the paint bucket assembly 33 to return to between the two sliding seats 32, other paints to be tested can be poured into the paint bucket assembly 33 again. When the ready-made paint bucket is directly fixed on the paint bucket assembly 33 and does not need to be cleaned, the cleaning step can be omitted, and the paint bucket can be directly replaced.

[0036] The shell 1 at the other end of the electric track assembly 31 is provided with a telescopic track 42, the telescopic track 42 is provided with an elastic assembly 43, the elastic assembly 43 is detachably fixed with a paint brush 44, the lifting assembly 34 is fixed with a pressing plate assembly 45 for driving the paint brush 44 to elastically stretch up and down, the shell 1 below the telescopic track 42 is fixed with a workbench 46 for placing a template, the workbench 46 is provided with templates such as glass and non-woven fabric which need to be coated with paint, different templates are selected according to different detection items, when the paint in the container cavity of the paint bucket assembly 33 is stirred uniformly by the stirring assembly 35, the electric track assembly 31 drives the two sliding seats 32 to move the paint bucket assembly 33 to the elastic assembly 43, then the pressing plate assembly 45 is pressed to make the related components on the elastic assembly 43 lower the paint brush 44, and the telescopic track 42 drives the pressing plate assembly 45 to move to make the paint brush 44 coat the paint on the template, so that the above structure completes the automatic coating of the paint on the template and the automatic cleaning of the related container, which saves the manual operation of the inspector and is more convenient and time-saving.

[0037] As the preferred technical scheme of the embodiment, the electric track assembly 31 comprises a horizontally installed electric track body 311, the electric track body 311 can drive the two sliding seats 32 to move in the form of a screw rod sliding rod, or can control the directional movement of the two sliding seats 32 by a linear motor structure, or a pneumatic structure, and the like, the electric track body 311 is provided with a gap a for the downward movement of the paint bucket assembly 33, when the two sliding seats 32 move on the electric track body 311, the paint bucket assembly 33 is relatively fixed on the electric track body 311 during the stirring and paint brush 44 material coating stages, only when cleaning is needed, the electric track body 311 moves the paint bucket assembly 33 to the gap a through the two sliding seats 32, and then the paint bucket assembly 33 is lowered under the driving of the lifting assembly 34 and the lifting assembly 34 and under the action of its own gravity.

[0038] As the preferred technical scheme of the embodiment, the paint bucket assembly 33 comprises a base 331 slidably installed between the two sliding seats 32, the base 331 is rotatably provided with a rotating disc 332, the rotating disc 332 is fixed with a paint bucket body 333, the paint bucket body 333 can be a barrel fixed on the rotating disc 332, a small amount of sample is put in each time for detection, and the paint bucket body 333 is automatically cleaned after detection, or the paint bucket body 333 is a finished paint bucket, at this time, the bottom of the rotating disc 332 can be provided with a suction cup to quickly suck the paint bucket to realize quick replacement of the paint bucket to be detected.

[0039] As the preferred technical solution of this embodiment, the lifting assembly 34 includes a bracket 341 as a mounting carrier, and a hydraulic cylinder 342 for driving the bracket 341 to rise and fall is fixed on the top of the outer shell 1. The hydraulic cylinder 342 drives the driven bracket 341 to accurately descend a certain distance. Of course, a baffle is provided at the bottom of the bracket 341 to prevent the horizontal track assembly 36 from falling off from its bottom, or other components can be provided that do not affect the normal sliding of the horizontal track assembly 36 and prevent it from falling directly from the bottom of the bracket 341, thereby cooperating with various components to perform actions.

[0040] As the preferred technical solution of this embodiment, the stirring assembly 35 includes a stirring blade 351 rotatably mounted on a bracket 341, and a motor 352 is fixed on the bracket 341 for driving the stirring blade 351 to rotate. When the paint bucket body 333 is located below the stirring blade 351, the bracket 341 descends. At this time, the horizontal track assembly 36 is placed on the electric track assembly 31 and will not move. The stirring blade 351 falls into the paint of the paint bucket body 333 as the bracket 341 descends. The motor 352 drives the stirring blade 351 to achieve uniform stirring of the paint, thereby preventing large errors in the detection results.

[0041] As the preferred technical solution of this embodiment, the horizontal track assembly 36 includes two slides 361 installed on the bracket 341 for sliding up and down, and a horizontal track body 362 is rotatably installed between the two slides 361. The base 331 is slidably installed on the horizontal track body 362, so as not to affect the movement of the two slides 32 driving the base 331. At the same time, when the base 331 moves to the notch a, it can be lifted and lowered with the lifting assembly 34 to realize the processing of excess paint in the paint bucket body 333 and the cleaning of the paint bucket body 333.

[0042] As the preferred technical solution of this embodiment, the elastic component 43 includes a base plate 431 that is transmission-mounted on the telescopic rail 42, two slide bars 432 are vertically fixed on the base plate 431, and a mounting seat 433 is slidably mounted on the two slide bars 432. A spring 434 is installed between the mounting seat 433 and the base plate 431, and a slot b for clamping the paint brush 44 is provided on the mounting seat 433. A card plate 435 that cooperates with the slot b to fix the paint brush 44 is rotatably mounted on the mounting seat 433. The card plate 435 and the slot b cooperate to facilitate the rapid replacement of the new paint brush 44 when detecting different paints. When the paint bucket body 333 moves to the position corresponding to the paint brush 44, the bottom plate 431 drives the paint brush 44 to move above the paint bucket body 333 under the action of the telescopic track 42, and then the pressure plate assembly 45 presses down on the mounting seat 433, so that the paint brush 44 extends into the paint to dip in the paint, and then the paint brush 44 rises again to exit the paint bucket body 333, and then the telescopic track 42 moves the paint brush 44 to the template on the workbench 46 through the bottom plate 431, and then the pressure plate assembly 45 presses down the mounting seat 433 again, so that the paint brush 44 applies the paint to the template during the movement.

[0043] As the preferred technical solution of this embodiment, the pressure plate assembly 45 includes a pressure plate body 451 fixed on the lifting assembly 34 for driving the compression mounting seat 433 to move up and down. When the paint bucket body 333 moves to a position corresponding to the paint brush 44, if the pressure plate body 451 needs to press down the mounting seat 433, the bracket 341 is lowered at this time, and the bracket 341 and the horizontal track assembly 36 slide relative to each other. The horizontal track assembly 36 is placed on the electric track assembly 31 and remains stationary, thereby completing the action of pressing the mounting seat 433 downward by the bracket 341 descending, so that the paint brush 44 dips the paint and applies the paint.

[0044] Example 2

[0045] Figure 6 In one embodiment of the present invention, by optimizing the mechanism of the rotating assembly 38 , the horizontal track assembly 36 can automatically complete the flipping process during the descent process, which is more convenient.

[0046] The second embodiment is more optimized than the first embodiment in that: the rotating assembly 38 includes gears 381 fixed to the two ends of the horizontal track body 362, and the bottom of the electric track assembly 31 is vertically fixed with a vertical guide rail 382 vertically slidably connected to the two ends of the horizontal track body 362. The vertical guide rail 382 allows the horizontal track body 362 to maintain its horizontal initial position again when it rises, and a rack 383 engaged with the gear 381 is fixed to the bottom of the vertical guide rail 382. When the horizontal track body 362 descends, the engagement of the gear 381 and the rack 383 completes the flipping of the horizontal track body 362, thereby driving the paint bucket body 333 to rotate. After the residual paint in the paint bucket body 333 is poured out, the bracket 341 descends again, and the electric track assembly 31 descends under the action of its own gravity, and finally the paint bucket body 333 is turned upside down in the cleaning liquid, and then rotated under the action of the driving assembly 39, and cleaned by centrifugal force.

[0047] Example 3

[0048] Figure 3 and Figure 5 As an embodiment of the present invention,

[0049] Compared with Example 1, Example 3 is more optimized in that: the drive assembly 39 includes a limit block 391 fixed to the lower part of the vertical track 37 for limiting the position of the horizontal track assembly 36. After the horizontal track assembly 36 descends to the limit block 391, it no longer descends. At this time, the paint bucket body 333 is upside down in the cleaning liquid. A pressure plate 392 is rotatably installed on the lifting assembly 34 and is driven by a belt with the stirring assembly 35. The bottom of the pressure plate 392 is used to squeeze the turntable 332 away from one side of the paint bucket body 333. As the bracket continues to descend, the pressure plate 392 is pressed against the pressure plate 392. At this time, the motor 352 rotates, so that the stirring blade 351 and the paint bucket body 333 rotate in the cleaning liquid to achieve cleaning.
