Description

Technical Field

[0001] The present invention relates to the technical field of spraying devices, and in particular to a device and a spraying process for uniformly spraying a mirror frame. Background Art

[0002] As we all know, a mirror frame is something that is mounted around a mirror to restrain, support or protect it. It is usually a frame made of wood, plaster or other materials and is mounted around the glass. Usually, the surface of the mirror frame is painted to improve the surface effect of the frame. The device for uniformly spraying the mirror frame is an auxiliary device for auxiliary spraying of paint on the surface of the mirror frame.

[0003] After searching, the Chinese patent publication number CN222197478U discloses a spraying device for a skylight frame, which is roughly described as comprising a spraying frame, a concave bracket and a bottom plate. The front and rear sides of the spraying frame are respectively provided with a shielding curtain, and concave brackets are provided on both sides of the spraying frame. A pipe is provided between the concave brackets, and a spray pump and a paint tank are provided at one end of the pipe. The positions of the corresponding connecting pipes in the spraying frame are fixed with a spray head by bolts. The spraying frame is provided with a bottom plate, and a second cross bar is provided on the top of the bottom plate. The two ends of the bottom of the second cross bar are connected by a rotating shaft. Install a rotating disk. The Chinese patent publication number CN116237180A discloses a spraying tool for glass edging, which is roughly described as including a frame, a spraying device is provided on the outside of the frame, an opening is provided near the bottom end on the side of the frame corresponding to the spraying device, and a clamp for fixing the glass edging is installed in the frame. The clamp has a clamping end adapted to the glass edging, and the clamping end is used to clamp the glass edging so that the edge of the glass edging is exposed at the opening, and the spraying device sprays the edge of the glass edging exposed at the opening.

[0004] Although the above two sets of existing technical solutions can both assist in achieving the spraying operation of the corresponding target parts, the structure of the nozzles has not been described in detail. Most of the nozzles currently on the market are conical structures, and when the nozzles are operating, the atomized paint will be distributed in a circular shape with the atomization point as the outlet. Therefore, when a single nozzle acts on the frame, the spray coverage is thicker in the area close to the nozzle and the area aligned with the nozzle, while the paint coverage in the area far away from the nozzle and the area diagonally opposite to the nozzle is thinner, the spraying uniformity is poor, and the spraying quality needs to be further improved.

[0015] A process for uniform spraying of a mirror frame comprises the following steps:

[0016] S1. When in use, first, the sandwich frame is moved away from the main column by adjusting the rotating assembly, then the target frame to be sprayed is supported and positioned by alternating the internal support clamping assemblies, and then the distance sensor is activated and the sandwich frame is moved closer to the main column by adjusting the rotating assembly;

[0017] S2. When the target frame is inserted relative to the sandwich frame and the distance sensor detects that the target frame and the sandwich frame have entered a suitable spraying distance, the further insertion movement of the target frame relative to the sandwich frame is stopped, and then the sandwich frame is caused to orbit relative to the target frame by adjusting the rotating assembly. During the orbiting movement, the distance sensor detects the relative distance between the sandwich frame and the target frame in real time, thereby adjusting the relative position of the target frame and the sandwich frame;

[0018] S3. After the target mirror frame is inserted into place relative to the sandwich frame, the re-suction pump is first started to form adsorption in the re-suction vertical pipe, and the air adsorbed in the re-suction vertical pipe is blown out through the gathering vertical pipe. Then, pressurized paint solution is supplied to the liquid supply pipe, and the pressure in the liquid supply pipe is ensured to be stable.

[0019] S4. The paint solution entering the liquid supply pipe is sprayed out through the top spray hole, the bottom spray hole and the side spray hole to form atomization. The atomized paint is coated relative to the target frame. During the coating operation, the sandwich frame forms a circular motion relative to the target frame to achieve full coverage of the target frame;

[0020] S5. When there is no paint liquid pressure in the liquid supply pipe, the pressure-adjusting fitting will keep the back-suction vertical pipe in a raised state relative to the sandwich frame to facilitate the insertion and removal of the target frame relative to the sandwich frame. During the spraying operation, the liquid supply pipe has the pressure of the paint liquid, so that the pressure-adjusting fitting is also in a pressurized state, so the back-suction vertical pipe will fall relative to the sandwich frame, so that the adsorption area of ​​the back-suction vertical pipe corresponds to the spraying area of ​​the sandwich frame.

[0042] The distance sensor 9, the first servo motor 20, the second servo motor 21, the third servo motor 30, the first electric telescopic rod 33 and the second electric telescopic rod 34 in this embodiment are all conventional devices purchased on the market and well known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and will not be described in detail here. The first servo motor 20, the second servo motor 21, the third servo motor 30, the first electric telescopic rod 33 and the second electric telescopic rod 34 are equipped with a central control machine, which has a display function. The display function of the central control machine can realize the reading of the measurement data of the distance sensor 9, and the corresponding drive control of the first servo motor 20, the second servo motor 21, the first electric telescopic rod 33 and the second electric telescopic rod 34 is formed according to the real-time data of the distance sensor 9.

[0043] To sum up, the working principle of the device for uniform spraying of frames and the spraying process is that when in use, first, the sandwich frame 4 is controlled to move away from the main column 2 by adjusting the rotating component, and the second servo motor 21 in the rotating component is energized to run. Under the meshing transmission action of the corresponding driving gear 40 and the transmission rack 42, the movement adjustment of the bent arm 22 relative to the rotating table 19 can be achieved, so as to achieve the relative adjustment of the sandwich frame 4 relative to the main column 2. After that, the target frame 1 to be sprayed is supported and positioned by the alternating internal support clamping component. When the alternating internal support clamping component is used, the third servo motor 30 is first controlled to run, and under the meshing transmission action of the driving gear 40 and the transmission half-tooth ring 43, the rotating disc frame 27 is moved relative to the fixed disc frame. 26 is rotated and adjusted so that the two first pairs of moving frames 31 and the two second pairs of moving frames 32 have an internal support structure that matches the target frame 1, and then the operator assisted in holding the target frame 1 so that the target frame 1 has a suitable relative height relative to the four inserted support rods 39. By first controlling the operation of the first electric telescopic rod 33, the first lifting frame 28 is height-adjusted relative to the main column 2. Under the transmission action of the two transmission frames 37 connected to the first lifting frame 28, the relative position adjustment of the two first pairs of moving frames 31 is realized, so that the two inserted support rods 39 connected to the two first pairs of moving frames 31 can form internal support and positioning corresponding to the two diagonal corners of the target frame 1. Then, the second electric telescopic rod 34 is operated to realize the height adjustment of the two second pairs of moving frames The relative position of 32 is adjusted so that the two insertion support rods 39 connected to the two second pairs of moving frames 32 can form internal support and positioning corresponding to the two diagonal corners of the target frame 1, and then the distance sensor 9 is started and the sandwich frame 4 is controlled to be close to the main column 2 by adjusting the rotating component. When the target frame 1 is inserted relative to the sandwich frame 4 and the distance sensor 9 detects that the distance between it and the target frame 1 has entered a suitable spraying distance, the further insertion movement of the target frame 1 relative to the sandwich frame 4 is stopped. Since the spraying distance is related to the pressure of the paint liquid supplied, the greater the pressure of the paint liquid supplied, the greater the spraying distance. Generally, the spraying distance is preferably 15 cm to 20 cm. After that, the sandwich frame 4 is formed relative to the main column 2 by adjusting the rotating component. The target mirror frame 1 is moved around, that is, the first servo motor 20 in the regulating rotating assembly is powered on and operated, and the corresponding driving gear 40 and the transmission gear ring 41 are meshed and driven to form the rotation drive and control of the rotating table 19 relative to the main column 2. The movement of the rotating table 19 drives the bending arm 22 to rotate, and the rotation of the bending arm 22 drives the sandwich frame 4 to rotate. During the moving around of the sandwich frame 4, the distance sensor 9 detects the relative distance between the sandwich frame 4 and the target mirror frame 1 in real time. The central control machine reads the detection data of the distance sensor 9 in real time, and forms the operation control of the second servo motor 21 according to the detection data, so as to realize the real-time sliding adjustment of the bending arm 22 relative to the rotating table 19, so as to cooperate with the maintenance of the relative distance between the sandwich frame 4 and the target mirror frame 1.The relative position between the target lens frame 1 and the sandwich frame 4 is adjusted.

[0044] Furthermore, after the target lens frame 1 is inserted into position relative to the sandwich frame 4, the re-suction pump 10 is first started to make the re-suction vertical pipe 11 form an adsorption effect, and the air adsorbed by the re-suction vertical pipe 11 is blown out through the gathering vertical pipe 12, and then the paint solution with pressure is supplied to the liquid supply pipe 8, and the pressure in the liquid supply pipe 8 is ensured to be stable. The paint solution entering the liquid supply pipe 8 will be sprayed out through the top spray hole 5, the bottom spray hole 6 and the side spray hole 7 to form atomization, and the atomized paint will form a coating operation relative to the target lens frame 1. During the coating operation, the sandwich frame 4 is formed relative to the target lens frame 1. The cam 16 is in the state of being covered by the elastic bag 16, and the elastic bag 16 overcomes the elastic force of the elastic spring 15, and stretches the cam 16, so that the cam 16 is lifted up and the cam 16 is lifted up. The back-suction vertical pipe 11 will fall relative to the sandwich frame 4 so that the adsorption area of ​​the back-suction vertical pipe 11 corresponds to the spraying area of ​​the sandwich frame 4 in height. In this state, the back-suction vertical pipe 11 can form negative pressure adsorption on the area corresponding to the sandwich frame 4, on the one hand, promoting the direction of the atomized paint in the sandwich frame 4, and on the other hand, recovering the paint that cannot be coated with the target detection frame in the suspended state, and finally forming the recycled paint for reuse through the two gathering vertical pipes 12. At the same time, the application of the gathering vertical pipe 12 can also promote the paint in the sandwich frame 4 to gather in the center, reducing the The atomized paint in 4 leaks out from both ends of the sandwich frame 4, thereby improving the utilization rate of the paint. As the sandwich frame 4 rotates and adjusts relative to the target frame 1, when the sandwich frame 4 moves through the diagonal area of ​​the target frame 1, the insertion support rod 39 corresponding to the diagonal position is controlled to be away from the target frame 1, so as to ensure that the diagonal position of the target frame 1 has a passing space that matches the sandwich frame 4 and the back-suction vertical pipe 11. After the sandwich frame 4 and the back-suction vertical pipe 11 pass through, the insertion support rod 39 separated from the target frame 1 is again tightly positioned relative to the target frame 1, as shown in the attached figure. Figure 1The state shown is that the sandwich frame 4 and the return suction vertical pipe 11 move through a diagonal position on the left side of the target frame 1 corresponding to the first pair of moving frames 31. At this time, the first electric telescopic rod 33 is powered on to control the two first pairs of moving frames 31 to move closer to each other, so that the corresponding insertion support rod 39 is away from the target frame 1, ensuring the smooth passage of the sandwich frame 4 and the return suction vertical pipe 11.

9. A process for uniform spraying of a mirror frame, characterized in that: The device for uniformly spraying a mirror frame according to any one of claims 1 to 8 is used, comprising the following steps: S1. When in use, first, the sandwich frame is moved away from the main column by adjusting the rotating assembly, then the target frame to be sprayed is supported and positioned by alternating the internal support clamping assemblies, and then the distance sensor is activated and the sandwich frame is moved closer to the main column by adjusting the rotating assembly; S2. When the target frame is inserted relative to the sandwich frame and the distance sensor detects that the target frame and the sandwich frame have entered a suitable spraying distance, the further insertion movement of the target frame relative to the sandwich frame is stopped, and then the sandwich frame is caused to orbit relative to the target frame by adjusting the rotating assembly. During the orbiting movement, the distance sensor detects the relative distance between the sandwich frame and the target frame in real time, thereby adjusting the relative position of the target frame and the sandwich frame; S3. After the target mirror frame is inserted into place relative to the sandwich frame, the re-suction pump is first started to form adsorption in the re-suction vertical pipe, and the air adsorbed in the re-suction vertical pipe is blown out through the gathering vertical pipe. Then, pressurized paint solution is supplied to the liquid supply pipe, and the pressure in the liquid supply pipe is ensured to be stable. S4. The paint solution entering the liquid supply pipe is sprayed out through the top spray hole, the bottom spray hole and the side spray hole to form atomization. The atomized paint is coated relative to the target frame. During the coating operation, the sandwich frame forms a circular motion relative to the target frame to achieve full coverage of the target frame; S5. When there is no paint liquid pressure in the liquid supply pipe, the pressure-adjusting fitting will keep the back-suction vertical pipe in a raised state relative to the sandwich frame to facilitate the insertion and removal of the target frame relative to the sandwich frame. During the spraying operation, the liquid supply pipe has the pressure of the paint liquid, so that the pressure-adjusting fitting is also in a pressurized state, so the back-suction vertical pipe will fall relative to the sandwich frame, so that the adsorption area of ​​the back-suction vertical pipe corresponds to the spraying area of ​​the sandwich frame.
