Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial robots, in particular to a wood-plastic floor bottom double-color synchronous spraying robot. BACKGROUND

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom mechanical devices for industrial fields, that is, industrial robots can automatically perform industrial production tasks such as carrying, welding, assembling, spraying, etc. under the control of preset programs or artificial intelligence technology, to replace or assist human labor and improve production efficiency and precision.

[0003] In the processing of wood-plastic floors, traditional single-color spraying robots need to be positioned and shielded multiple times to complete the coloring operation on wood-plastic floors. This coloring method is not only cumbersome, but also prone to boundary misplacement due to repeated positioning, resulting in an increased rate of defective products. Therefore, in order to improve the yield of wood-plastic floors, a double-color synchronous spraying robot is needed for coloring on the floor of a wood-plastic floor.

[0004] The existing double-color synchronous spraying robot stores paint in the storage box. During storage, volatile organic compounds (VOCs) gas is continuously generated. These gases accumulate in the empty space inside the storage box, forming a certain concentration of harmful gas environment. When the storage box needs to be refilled with paint or replaced due to paint depletion or color change, the box cover must be removed first. This operation breaks the original seal of the storage box, and the VOCs gas accumulated inside the storage box will quickly escape to the workshop where the operator is located, directly polluting the air in the work area. If these VOCs gases are inhaled by the on-site operator, it will cause irritation to the respiratory system, nervous system, etc. of the operator, threatening the health of the operator. However, the existing double-color synchronous spraying robot does not have a purification function for volatile organic compound gas, so this situation cannot be avoided.

[0005] Therefore, we propose a new wood-plastic floor bottom double-color synchronous spraying robot to solve the problems raised in the above background technology. SUMMARY

[0036] In this embodiment, when the storage box 102 needs to be refilled with paint, the lower two first control valves 210 and the second control valve 215 and the plasma purifier 201 are opened, the sealing plug 207 is removed from the box cover 206, and the air compressor 119 is opened. At this time, the compressed air in the air tank on the air compressor 119 will first enter the interior of the opened second control valve 215, then enter the interior of the second connecting pipe 216, and then be shunted into the interior of the multi-stage shunt pipe 211. Then, the air passes through the interior of the opened first control valve 210 and enters the interior of the corresponding first circular pipe 209. After that, the air enters the interior of the storage box 102, blows away the volatile organic compound gas accumulated in the empty space in the interior of the storage box 102, and then the blown air first enters the interior of the second circular pipe 212, then enters the interior of the first connecting pipe 213, and then enters the interior of the corrosion-resistant pipe 217. Then, the air is collected into the interior of the collecting pipe 208, and then enters the interior of the plasma purifier 201. When the volatile organic compound gas enters the interior of the plasma purifier 201, the started plasma purifier 201 processes the air mixed with the volatile organic compound gas. When the air is processed and discharged from the air outlet end of the plasma purifier 201, the purified air first enters the interior of the communication pipe 202, then enters the interior of the shunt 204, and then is transported into the interior of the treatment tank 203. The air contacts the adsorption block 205, so that the adsorption block 205 adsorbs and removes ozone gas, carbon dioxide gas, water vapor and carbon monoxide gas. Then, the air is discharged into the environment. Similarly, when the storage box 102 needs to be replaced, the upper two first control valves 210 are opened, the previously opened two first control valves 210 are closed, and then the above operation steps are repeated.

[0037] The effect and working principle of the whole mechanism are as follows: before work, remove the two check valves 104, then inject paint into the interior of the corresponding storage box 102 through the air inlet at the top of the box cover 103, and the two paints are different in color. After the two paints are filled, the two check valves 104 are installed back to the corresponding positions.

[0038] When working, the control cabinet 123 starts the mechanical arm 122, the started mechanical arm 122 moves according to the preset program, the moving L-shaped rod 113 drives the double-color spray gun 114 and the components installed on the double-color spray gun 114 to move, when the discharge end of the double-color spray gun 114 is aligned with the wood-plastic floor in the fixed state and needs to be colored, the control cabinet 123 suspends the position movement of the double-color spray gun 114, and then the control cabinet 123 starts the double-shaft motor 107 and the air compressor 119;

[0039] When the double-shaft motor 107 is started, the two pump heads 109 are started through the two couplings 108, so that the two pump heads 109 obtain suction at the two feeding ends, at the same time, the control cabinet 123 opens the two first electric valves 106 and the two flow regulating valves 117, so that the inside of the storage box 102 is connected with the inside of the liquid outlet pipe 111, at this time, the feeding end of the started pump head 109 is connected with the first electric valve 106 through the liquid inlet pipe 110, so that the paint in the inside of the storage box 102 is sucked out, and then the sucked paint enters the inside of the liquid outlet pipe 111, the inside of the pipe 112, the inside of the opened flow regulating valve 117, the inside of the arc-shaped pipe 116, the inside of the one-way valve 115, and then enters the two paint channels in the inside of the double-color spray gun 114, and continues to move to the corresponding outlet;

[0040] When the air compressor 119 is started, the air in the environment is filtered through the filter 120 and then sucked, and then the sucked air is compressed and stored in the gas storage tank, when the compressed air needs to be used, the control cabinet 123 opens one of the second electric valves 121, so that the compressed air in the gas storage tank of the air compressor 119 is directly released, and then the air enters the inside of the gas pipe 118 through the inside of the opened second electric valve 121, and then enters the gas channel in the inside of the double-color spray gun 114, and continues to move to the corresponding outlet;

[0041] When the two paints and the compressed air are sprayed from the corresponding outlets of the double-color spray gun 114, the compressed air sprayed from the double-color spray gun 114 disperses the sprayed two paints, and then the sprayed two paints are sprayed on the bottom surface of the wood-plastic floor, when the spraying operation of the bottom surface of the wood-plastic floor is completed, the spraying operation of the double-color spray gun 114 is stopped, and the mechanical arm 122 is reset to the original position, then the sprayed wood-plastic floor is taken out, another wood-plastic floor needing to be sprayed with double colors is placed, and the spraying operation is continued, at the same time, the control cabinet 123 can monitor the conveying of the paint in real time through the pressure sensor 126, and when a problem occurs, the alarm 124 alarms in time to remind the operator;

[0042] When the paint supply box 102 needs to be refilled, the control cabinet 123 opens the two first control valves 210 and second control valves 215 below and the plasma purifier 201, and removes the sealing plug 207 from the box cover 206. The compressed air in the air tank of the air compressor 119 enters the second connecting pipe 216 through the opened second control valve 215, then enters the first branch of the multi-stage shunt pipe 211, and then enters the second branch of the multi-stage shunt pipe 211. The compressed air enters the inside of the corresponding first circular pipe 209 through the inside of the opened first control valve 210. When the compressed air is sprayed from the air outlet end of the first circular pipe 209 and enters the inside of the paint supply box 102, the volatile organic compound gas accumulated in the empty space inside the paint supply box 102 is blown away and enters the inside of the corresponding second circular pipe 212. The air mixed with volatile organic compound gas enters the inside of the corrosion-resistant pipe 217, then enters the inside of the shunt pipe 208, and then enters the inside of the plasma purifier 201. When the volatile organic compound gas enters the inside of the plasma purifier 201, the plasma purifier 201 is started to form a strong electric field between the electrodes in the inside of the plasma purifier 201. The free electrons in the electric field obtain very high energy under the acceleration of the strong electric field and become “high-energy electrons”. When the volatile organic compound gas enters the plasma reaction zone, the high-energy electrons will directly bombard the chemical bonds of the VOCs molecules, i.e. the stable VOCs macromolecules are disintegrated into unstable free radicals or small molecular fragments. At the same time, a large number of strong oxidizing free radicals are also generated in the plasma reaction zone. Then, these active free radicals react with the generated “VOCs intermediates (free radicals, small molecular fragments) ” to gradually oxidize into simpler harmless inorganic small molecules. Part of the VOCs fragments or free radicals that are not completely oxidized will be electrostatically adsorbed with positive and negative ions in the plasma. The volatile organic compound gas that has been treated will be discharged from the air outlet end of the plasma purifier 201, first enters the inside of the communication pipe 202 (at this time, the main components of the gas entering the inside of the communication pipe 202 are carbon dioxide gas, water vapor, a small amount of ozone gas and a very small amount of carbon monoxide gas), then enters the inside of the shunt 204, and then is discharged from each air outlet on the shunt 204 and contacts the adsorption block 205. At this time, the adsorption block 205 (activated carbon) adsorbs and removes the ozone gas, carbon dioxide gas, water vapor and carbon monoxide gas. Then, the air that is treated again enters the inside of the box cover 206 and is discharged into the environment. Similarly, when the paint supply box 102 needs to be replaced, the control cabinet 123 opens the two first control valves 210 above, closes the two first control valves 210 that were opened before, and then repeats the above operation steps.
