Description

Technical Field

[0001] This invention relates to the field of sheet metal spraying, and more particularly to an intelligent spraying production line for processing reconstituted sheet metal. Background Technology

[0002] Reconstituted bamboo, also known as reconstituted bamboo or bamboo fiberboard, is a new type of bamboo material that has undergone special treatment. Reconstituted bamboo has high density and high hardness, and its properties are more stable. It is not easily affected by moisture and will not crack or deform due to prolonged soaking.

[0003] However, after the pretreatment of reconstituted bamboo, it needs to be painted using a coloring machine. Due to differences in processing techniques, the texture of reconstituted bamboo also varies. Therefore, when simply using a regular coloring machine for painting, it is impossible to treat the pits or cracks on the surface of the reconstituted bamboo. The paint tends to penetrate into the pits or cracks on the surface of the reconstituted bamboo. The paint in the pits or cracks does not dry easily, so the paint in the pits or cracks still has a certain degree of fluidity. When the reconstituted bamboo is transferred later, the paint in the pits is easy to flow out, resulting in uneven coating on the surface of the reconstituted bamboo and affecting the quality of the finished reconstituted bamboo. Summary of the Invention

[0004] The technical problem of this invention is:

[0005] To overcome the shortcomings of being unable to spray paint on pits or cracks on the surface of reconstituted bamboo, the paint not drying well in pits or cracks, and the paint flowing out of pits, resulting in uneven coating on the surface of reconstituted bamboo, this invention provides an intelligent spraying production line for processing reconstituted bamboo boards.

[0047] See appendix Figures 1 to 7 The specific process is as follows:

[0048] Connect the conveyor table 1, linear electric slide rail 2, vision sensor 6, electric actuator I 8, annular electric slide rail 101, electric slide bar I 103, electric nozzle I 105, electric slide bar II 202, and electric nozzle II 204 to the power supply.

[0049] Connect the feed pipe 5 to the paint pump;

[0050] First, the robotic arm transfers the heavy bamboo board body 001 to the conveyor table 1, arranging it neatly. Then, the conveyor table 1 is started, horizontally transporting the heavy bamboo board body 001. When the heavy bamboo board body 001 passes under the vision sensor 6, the vision sensor 6 scans the surface of the heavy bamboo board body 001. Next, the heavy bamboo board body 001 passes under the paint tank 4, where an external paint pump pumps paint into the paint tank 4 and applies pressure to the paint. The paint then enters the hopper 4001 through the conveying pipe 5. The paint in the hopper 4001 is then introduced into the corresponding hollow connecting rod 10 through two branch pipes I11. The paint enters the spray pipe 7. To adapt to spraying different thicknesses of the bamboo board body 001, the two electric actuators I8 can be controlled to retract and extend, synchronously driving the crossbar 9 and its corresponding parts to move, so that the spray pipe 7 can move up or down. At this time, the distance sensor at the bottom of the spray pipe 7 is used to detect the actual distance between the spray pipe 7 and the bamboo board body 001. When the distance between the bamboo board body 001 and the spray pipe 7 is appropriate, the two electric actuators I8 are controlled to close. Then the atomizing nozzle on the spray pipe 7 sprays the paint onto the surface of the bamboo board body 001, completing the surface spraying of the bamboo board body 001.

[0051] Next, based on the scanning results from the vision sensor 6, the conveyor belt of the conveyor table 1 is stopped from transporting the reconstituted bamboo board body 001. Then, the two electric sliders I3 are controlled to move to the right on the corresponding linear electric slide rail 2, synchronously driving the paint tank 4 and its corresponding parts to move together. Based on the location of the defect on the reconstituted bamboo board body 001 scanned by the vision sensor 6, the spray pipe 7 is moved to the vicinity of the defect location on the reconstituted bamboo board body 001, and the two electric sliders I3 are stopped. Then, the two electric sliders II 102 are controlled to move downward on the corresponding annular electric slide rail 101, synchronously driving the electric slide rod I 103 and its corresponding parts move downwards until the electric nozzle I 105 approaches the defective position on the reconstituted bamboo board body 001. At this time, the atomizer on the spray pipe 7 stops atomizing the paint, and the pressure of the paint in the spray pipe 7 forces the paint through the branch pipe II 106 into the hollow electric slide rod I 103. Then the paint reaches the electric nozzle I 105 through each diversion joint 108 and the telescopic pipe I 109. At this time, the electric nozzle I 105 sprays the paint onto the defective position on the reconstituted bamboo board body 001, filling the defect and making the surface of the reconstituted bamboo board body 001 smooth.

[0052] Considering that the defects on the reconstituted bamboo board body 001 may not only be pits, but may also include cracks, if the direction of crack expansion is consistent with the extension direction of the linear electric slide rail 2, simply control the electric slider I3 to move left and right, and simultaneously make the electric spray head I105 move left and right, while accurately spraying paint to complete the filling work of the crack. Targeted spraying of the defects on the reconstituted bamboo board body 001 ensures that the paint is evenly covered on the defective areas of the reconstituted bamboo board body 001, effectively improving the quality of the spraying.

[0053] If the direction of crack expansion is inconsistent with the extension direction of the linear electric slide rail 2, such as when the crack is tilted on the reconstituted bamboo board body 001, the electric slider III 104 near the crack on the reconstituted bamboo board body 001 can be controlled to move back and forth on the electric slide rod I 103, simultaneously driving the electric nozzle I 105 to move back and forth. The telescopic tube I 109 extends or retracts in coordination with the movement of the electric nozzle I 105, and then moves left and right in coordination with the electric slider I 3. In this way, the filling range of the electric nozzle I 105 on the reconstituted bamboo board body 001 can cover the entire reconstituted bamboo board body 001, so that all the cracks on the reconstituted bamboo board body 001 can be fully filled. At the same time, in order to obtain higher crack filling efficiency on the reconstituted bamboo board body 001, multiple electric sliders III 104 can be set on the electric slide rod I 103, and matched with a corresponding number of electric nozzles I 105, so as to achieve rapid filling treatment of defects on the reconstituted bamboo board body 001 and effectively improve the spraying efficiency.

[0054] During the above operations, it should also be considered that the paint sprayed on the reconstituted bamboo board body 001 needs to be dried afterward. Since more paint is filled in the defects of the reconstituted bamboo board body 001, simply drying the reconstituted bamboo board body 001 will not allow the paint in the defects to dry fully. This will result in the paint in the defects of the reconstituted bamboo board body 001 still having fluidity. When the reconstituted bamboo board body 001 is moved later, the paint in the defects of the reconstituted bamboo board body 001 is easy to flow out, causing the paint on the surface of the reconstituted bamboo board body 001 to be uneven and rough.

[0055] Therefore, after filling the defects in the reconstituted bamboo board body 001, the electric spray head I 105 is reset. Then, the two electric sliders IV 201 are moved downwards synchronously on the corresponding annular electric slide rails 101, simultaneously driving the electric slide rod II 202 and its corresponding parts downwards, so that the electric spray head II 204 approaches the paint filling area of ​​the reconstituted bamboo board body 001. The two electric sliders IV 201 are then stopped. Next, the electric spray head II 204 draws air from the spray pipe 7 through the air hole 20501 of the air pipe 205. The spray pipe 7 then draws air from the outside air through the upper air valve 7001. The outside air enters the spray pipe 7, and then enters the hollow electric slide rod II 202 through the air pipe 205. Then, the air reaches each electric spray head II 204 through the corresponding diverter 108 and telescopic pipe II 207 on the electric slide rod II 202. At this time, the electric spray head II 204 sprays out the air while also spraying the air. Air heating is used to spray heated air onto defects in the reconstituted bamboo board 001, pre-drying the coating on these defects. The reconstituted bamboo board 001 is then fed into subsequent drying equipment for simultaneous drying, ensuring uniform coating drying across its surface and preventing coating leakage from defects that could affect surface smoothness. For cracks, electric slider V203 can move on electric slider II202, working in conjunction with electric slider I3, to specifically pre-dry the coating at these defects. Multiple electric nozzles II204 can also be installed to simultaneously pre-dry the coating at defects, improving processing efficiency and facilitating automated control by the enterprise.

[0056] Furthermore, only a small portion of the paint is needed to repair the defect 001 on the heavy bamboo board body. Most of the paint remains inside the spray pipe 7. Some of the paint in the spray pipe 7 will settle, causing the paint concentration at the bottom of the spray pipe 7 to gradually increase. When the ambient temperature is high, the paint in the spray pipe 7 is prone to curing, and the settling speed of the paint at the bottom of the spray pipe 7 will accelerate. When the electric nozzle II204 sprays hot air, air is drawn from the spray pipe 7, and the spray pipe 7 will also draw air from the outside through the air valve 7001. Therefore, the outside air will flow inside the spray pipe 7, which will also cool the paint inside the spray pipe 7. This effectively avoids the paint from curing when the temperature is too high, which would result in an excessive thickness of paint at the bottom of the spray pipe 7 and affect the spraying of paint from the spray pipe 7.

[0057] Second embodiment

[0058] Based on the first embodiment, according to Figure 1-7As shown, a protective mesh is installed on the vision sensor 6. The protective mesh is detachable and is used to block splashed paint.

[0059] Looking from left to right, the longitudinal section of spray tube 7 is shaped like a large teacup.

[0060] The lower part of branch pipe II106 is fixedly connected to the inner wall of spray pipe 7, and multiple small holes are opened on the lower side wall of branch pipe II106.

[0061] Based on the above embodiments, considering the need for a vision sensor 6 to scan defects in the reconstituted bamboo board body 001, and the subsequent need for the spraying pipe 7 to spray coating onto the surface of the reconstituted bamboo board body 001, the atomized coating disperses in the air. This coating can easily adhere to the vision sensor 6, obstructing its line of sight and affecting its scanning accuracy. Figure 1 As shown, a detachable protective screen can be installed on the vision sensor 6 to intercept splashed paint and prevent paint from contaminating the vision sensor 6. After a certain amount of paint is intercepted on the protective screen of the vision sensor 6, the operator can remove the protective screen and replace it with a new one to avoid production line downtime, reduced production line capacity, and significant economic losses. It also reduces the maintenance of the vision sensor 6 and saves the company's investment in production materials.

[0062] It should also be considered that when the atomizer of the spray pipe 7 stops atomizing the paint, and the defects in the reconstituted bamboo board body 001 are filled, the electric spray head I105 only needs to spray a small amount of paint to fill the defects in the reconstituted bamboo board body 001. Therefore, a large amount of paint remains in the spray pipe 7, and the filling process also requires a certain amount of time. During this time, some of the paint will settle in the spray pipe 7, causing the paint concentration in the spray pipe 7 to gradually increase from top to bottom. Figure 7 As shown, the spray pipe 7 is designed with a flat top and a round, teacup-shaped bottom. The settled paint gradually gathers towards the middle of the spray pipe 7. Meanwhile, the paint in the spray pipe 7 also enters the branch pipe II 106 through the small hole at the bottom. To avoid the paint concentration sprayed by the electric nozzle I 105 being lower than that sprayed by the atomizer of the spray pipe 7, which would result in a higher solvent ratio and greater fluidity of the paint at the defect filling point of the reconstituted bamboo board 001, making it easier for the paint to flow out from the defect, the branch pipe II 106 is fixed near the middle of the spray pipe 7. The paint entering the branch pipe II 106 from this point has a higher concentration and a higher solute ratio than the paint at the top of the spray pipe 7. After filling the defect of the reconstituted bamboo board 001, the paint loss after drying is small, and the defect filling effect of the reconstituted bamboo board 001 is better.
