Description

Technical Field

[0001] This invention relates to the field of powder coating robots, and particularly to an automated powder coating robot. Background Technology

[0002] Powder coating is a process in which powder coating equipment (electrostatic powder coating machine) sprays powder coating onto the surface of a workpiece. Under the action of static electricity, the powder will be evenly adsorbed onto the surface of the workpiece to form a powdery coating. The powdery coating is then baked at high temperature to flow and cure, becoming a final coating with different effects (different types of powder coating). The coating effect of powder coating is superior to that of spray painting in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance, but the cost is higher than that of spray painting.

[0003] However, the powder coating process can easily generate a large amount of dust (particulate) gas, which can affect the health of the surrounding workers.

[0004] Therefore, it is necessary to propose an automated powder coating robot to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automated powder coating robot to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated powder coating robot, comprising a coating robotic arm and a dust removal mechanism, wherein the coating robotic arm comprises a support base, a first motor, a rotating base, a connecting arm, a second motor, a first rotating arm, a third motor, a second rotating arm, and a spray gun; the first motor is fixedly mounted on the upper surface of the support base; the rotating base is disposed above the first motor and fixedly mounted on the rotating shaft of the first motor; the connecting arm is integrally disposed on the upper surface of the rotating base; the second motor is fixedly mounted on the connecting arm; the rotating shaft of the second motor is fixedly fixed to the lower end of the first rotating arm; the third motor is fixedly mounted on the upper end of the first rotating arm; the rotating shaft of the third motor is fixedly fixed to the second rotating arm; the third motor is fixedly mounted on the side of the second rotating arm; and the spray gun is disposed at the end of the second rotating arm away from the first rotating arm.

[0007] The dust removal mechanism includes a rectangular shell structure with openings at both ends. Sealing plates seal both openings. An air intake is located at one end of the shell, and the intake is located on all four sides of the shell, connecting the inside and outside of the shell. An exhaust box is fixedly installed on the upper surface of the other end of the shell, with an exhaust port on the side of the exhaust box away from the intake. A drying duct is connected to the dust removal mechanism, with an exhaust port at one end and an inlet at the other. The inlet connects to the exhaust port. A workpiece to be coated is placed between the spray gun and the dust removal mechanism. The exhaust port faces the workpiece closer to the spray gun, and the intake port is located on the side of the workpiece away from the spray gun.

[0008] Preferably, a material pump is fixedly installed on the rotating base, the material pump is provided with a material inlet end, and the material pump is also provided with a connecting pipe. The connecting pipe is installed on the first rotating arm along the direction of the first rotating arm and is secured with a clamp. A U-shaped mounting groove is provided on the side of the second rotating arm away from the first rotating arm.

[0009] In this invention, a spraying robot arm operates a spray gun to spray the workpiece to be sprayed. During the spraying process, a dust removal mechanism is used to remove the particulate gas generated, and the air force that removed the particulate gas is blown back onto the surface of the workpiece to be sprayed, so as to quickly dry the surface of the workpiece during the spraying process.

[0010] During operation, a material tank is connected to the material feed end. The material tank stores powder material to be sprayed onto the surface of the workpiece. When the material pump is started, the powder material is sucked into the spray gun from the connecting pipe. The spray gun then sprays the powder material onto the surface of the workpiece.

[0011] When the surface of the workpiece to be coated is sprayed by the spray gun, the fourth motor starts. The fourth motor drives the turbine to rotate and generate air force. The air force passes through the air intake, the first filter layer, and the turbine housing to enter the upper part of the second filter layer. When the air force passes through the first filter layer, the first filter layer filters out the particulate impurities it contains. The second filter layer further filters out the particulate matter in the air force and then delivers the air force to the lower filter chamber. The air force in the lower filter chamber passes through the middle of the second filter layer and then enters the reverse filter cylinder. The air force in the reverse filter cylinder passes through the reverse filter box and enters the first metal heat exchange pipe. The air force passes through the lower end of the first metal heat exchange pipe and enters the lower end of the first chamber. The air force in the lower end of the first chamber enters through the lower end of the second metal heat exchange pipe and then enters the interior of the air outlet box. The air force entering the air outlet box passes through the air inlet, the drying pipe, and the air outlet and is blown to the side of the workpiece to be coated by the spray gun to dry the surface of the workpiece.

[0012] Preferably, the second rotating arm has a channel inside, one end of which is connected to a connecting pipe, and the other end of which is connected to the interior of a U-shaped mounting groove. A spray gun is installed at the end of the U-shaped mounting groove away from the first rotating arm, and the spray gun is connected to the end of the channel that is connected to the U-shaped mounting groove via a flexible hose.

[0013] In the device, the mounting base for the spray gun is installed on a U-shaped mounting groove, which facilitates disassembly and replacement, and makes it easy to use different models of spray guns.

[0014] Preferably, the housing is provided with a first chamber, a second chamber and a third chamber arranged in sequence. The first chamber is close to the air outlet box and the third chamber is close to the air inlet. A turbine housing is fixedly provided in the middle of the second chamber. A fourth motor is provided on the turbine housing. A turbine is installed on the shaft of the fourth motor. One end of the turbine housing is open and communicates with the third chamber, and the other end of the turbine housing is also open and communicates with the first chamber.

[0015] The fourth motor and turbine are each installed on both sides of the second chamber, ensuring that there is a spare turbine. This avoids the situation where the other turbine cannot work properly due to excessive particles blocking it. Furthermore, when both turbines are turned on at the same time, the drying efficiency and the gas purification efficiency can be increased.

[0016] Preferably, a first filter layer is installed in the third chamber.

[0017] It should be noted that both the first and second filter layers can use composite filter layers such as PP cotton layer, filter cotton layer and activated carbon layer to fully purify the gas, which is beneficial for the purification and treatment of particulate gas and harmful gas generated during the spraying process.

[0018] Preferably, a second filter layer is fixedly installed in the first chamber, and a lower filter chamber is formed between the lower part of the second filter layer and the inner wall of the first chamber. A reverse filter cylinder is fixedly installed on the upper surface of the second filter layer, and the lower end of the reverse filter cylinder is open.

[0019] It should be noted that when the reverse filter cartridge and the second filter layer are combined, the gas can pass through the second filter layer from top to bottom and then pass through the purification path from bottom to top again to perform a third purification using the same set of second filter layers. Furthermore, the gas is more likely to detach particulate matter as it moves from bottom to top, thus increasing the purification effect.

[0020] Preferably, the upper end of the reverse filter cartridge is integrally provided with a reverse filter box, the reverse filter box is connected to the first metal heat exchange pipe, the lower end of the first metal heat exchange pipe is connected to the lower end of the first chamber, and a second metal heat exchange pipe is provided on both sides of the first metal heat exchange pipe, the upper end of the second metal heat exchange pipe is connected to the interior of the air outlet box, and the lower end of the second metal heat exchange pipe is connected to the lower end of the first chamber.

[0021] Furthermore, the gas passes evenly through the first and second metal heat exchange pipes, where it can be cooled down. This ensures that the airflow used to dry the surface of the workpiece to be coated maintains a suitable temperature, preventing high-temperature baking that would cause the powder material on the surface of the workpiece to be coated to fall off. This maintains the purpose of low-temperature air drying and makes full use of the wind power during gas purification.

[0022] Preferably, when the fourth motor drives the turbine to rotate, it generates wind power. The wind power passes through the air intake, the first filter layer, and the turbine housing in sequence and enters the upper part of the second filter layer. The second filter layer filters out particulate matter from the wind power and then delivers the wind power to the lower filter chamber. The wind power in the lower filter chamber is filtered again at the middle position of the second filter layer and then enters the reverse filter cylinder. The wind power entering the reverse filter cylinder passes through the reverse filter box and enters the first metal heat exchange pipe. The wind power passes through the lower end of the first metal heat exchange pipe and enters the lower end of the first chamber. The wind power inside the lower end of the first chamber enters through the lower end of the second metal heat exchange pipe and then enters the interior of the air outlet box.

[0023] Preferably, the air entering the air outlet box passes sequentially through the air inlet, air drying duct, and air outlet, and is blown onto the side of the workpiece to be sprayed by the spray gun.

[0024] In the device, the connecting pipe is installed on the first rotating arm by a clamp for easy arrangement. The first motor can drive the rotating base and the above structure to rotate, so as to realize the purpose of the spray gun rotating in the horizontal plane around the first motor shaft. The second motor can control the rotation of the first rotating arm, and the third motor can control the rotation of the second rotating arm, thereby adjusting the height and tilt angle of the spray gun, which is convenient to use.

[0025] Preferably, the turbine housing is equipped with an alarm for monitoring material blockage inside.

[0026] When the alarm sounds, it allows people to promptly clear blockages from the turbine housing.

[0027] The technical effects and advantages of this invention are as follows:

[0028] 1. An automated powder coating robot of the present invention includes a spraying robotic arm and a dust removal mechanism. The spraying robotic arm includes a support base, a first motor, a rotating base, a connecting arm, a second motor, a first rotating arm, a third motor, a second rotating arm, and a spray gun. The first motor is fixedly installed on the upper surface of the support base. In the present invention, the spraying robotic arm operates the spray gun to spray the workpiece to be sprayed. During the spraying process, the dust removal mechanism removes the particulate gas generated, and the wind force of the particulate gas is used to blow it back onto the surface of the workpiece to be sprayed, so as to quickly dry the surface of the workpiece to be sprayed during the spraying process.

[0029] 2. An automated powder coating robot of the present invention has a material tank connected to the material feed end. The material tank stores powder to be sprayed on the surface of the workpiece. When the material pump is started, the powder is sucked into the spray gun from the connecting pipe. The spray gun sprays the powder onto the surface of the workpiece.

[0030] 3. An automated powder coating robot of the present invention, when the surface of the workpiece to be coated is sprayed by the spray gun, the fourth motor is started. The fourth motor drives the turbine to rotate and generate wind. The wind passes through the air inlet, the first filter layer, and the turbine housing in sequence and enters the upper part of the second filter layer. When the wind passes through the first filter layer, the first filter layer initially filters out the particulate impurities contained therein. The second filter layer further filters out the particulate matter in the wind and then delivers the wind to the lower filter chamber. The wind in the lower filter chamber is filtered again at the middle position of the second filter layer and then enters the reverse filter cylinder. The wind entering the reverse filter cylinder passes through the reverse filter box and enters the first metal heat exchange pipe. The wind passes through the lower end of the first metal heat exchange pipe and enters the lower end of the first chamber. The wind inside the lower end of the first chamber enters through the lower end of the second metal heat exchange pipe and then enters the interior of the air outlet box. The wind entering the air outlet box passes through the air inlet, the drying pipe, and the air outlet in sequence and is blown to the side of the workpiece to be coated by the spray gun to dry the surface of the workpiece.

[0031] 4. In an automated powder coating robot of the present invention, a fourth motor and a turbine are provided on each side of the second chamber, ensuring that there is a spare turbine and avoiding the phenomenon that the other turbine cannot work when it is blocked by too many particles. When both turbines are turned on at the same time, the drying efficiency and the gas purification efficiency can be increased.

[0032] 5. The automated powder coating robot of the present invention, after the reverse filter cylinder and the second filter layer are combined, allows the gas to pass through the second filter layer from top to bottom for secondary filtration and then pass through the purification path from bottom to top again to perform a third purification of the gas using the same set of second filter layers. Moreover, the gas is more likely to detach particulate matter when it passes from bottom to top, which increases the purification effect of the gas.

[0033] 6. The automated powder coating robot of the present invention allows gas to pass uniformly through the first metal heat exchange pipe and the second metal heat exchange pipe, which can be cooled down so that the wind force used to dry the surface of the workpiece to be coated maintains a suitable temperature, and there will be no phenomenon of high temperature baking that causes the powder material on the surface of the workpiece to be coated to fall off. This maintains the purpose of low temperature air drying and makes full use of the wind power during gas purification. Attached Figure Description

The rotating base 3 is disposed above the first motor 2 and is fixedly mounted on the rotating shaft of the first motor 2. The connecting arm 4 is integrally disposed on the upper surface of the rotating base 3. The second motor 5 is fixedly mounted on the connecting arm 4. The rotating shaft of the second motor 5 is fixed to the lower end of the first rotating arm 6. The third motor 7 is fixedly mounted on the upper end of the first rotating arm 6. The rotating shaft of the third motor 7 is fixed to the second rotating arm 8. The third motor 7 is fixedly mounted on the side of the second rotating arm 8. The spray gun 9 is disposed at the end of the second rotating arm 8 away from the first rotating arm 6.

[0041] The dust removal mechanism 16 includes a housing 20 with a rectangular shell structure. The housing 20 has openings at both ends, and sealing plates 27 are sealed at both ends of the openings. An air intake 23 is provided at one end of the housing 20. The air intake 23 is provided on all four sides of the housing 20 and connects the inside and outside of the housing 20. An air outlet box 25 is fixedly installed on the upper surface of the other end of the housing 20. An air outlet 26 is provided on the side of the air outlet box 25 away from the air intake 23. A drying duct 17 is matched and connected to the dust removal mechanism 16. An air outlet 19 is provided at one end of the drying duct 17, and an air inlet 18 is provided at the other end. The air inlet 18 is connected to the air outlet 26. A workpiece 15 to be sprayed is stored between the spray gun 9 and the dust removal mechanism 16. The opening of the air outlet 19 faces the side of the workpiece 15 to be sprayed that is closer to the spray gun 9, and the air intake 23 is located on the side of the workpiece 15 to be sprayed that is away from the spray gun 9.

[0042] A material pump 13 is fixedly installed on the rotating base 3. The material pump 13 is provided with a material feed end 14 and a connecting pipe 11. The connecting pipe 11 is installed on the first rotating arm 6 along the direction of the first rotating arm 6 and is installed on the first rotating arm 6 using a clamp 12. A U-shaped mounting groove 10 is provided on the side of the second rotating arm 8 away from the first rotating arm 6.

[0043] In this invention, the spraying robot arm operates the spray gun 9 to spray the workpiece 15 to be sprayed. During the spraying process, the dust removal mechanism 16 removes the particulate gas generated, and the wind force that removes the particulate gas is blown back onto the surface of the workpiece 15 to be sprayed, so as to quickly dry the surface of the workpiece 15 during the spraying process.

[0044] During operation, a material tank is connected to the material feed end 14. The material tank stores powder material to be sprayed onto the surface of the workpiece 15. When the material pump 13 is started, the powder material is sucked into the spray gun 9 from the connecting pipe 11. The spray gun 9 sprays the powder material onto the surface of the workpiece 15.

[0045] When the surface of the workpiece 15 to be sprayed is sprayed by the spray gun 9, the fourth motor 22 starts. The fourth motor 22 drives the turbine to rotate, generating airflow. The airflow passes sequentially through the air intake 23, the first filter layer 34, and the turbine housing 21, entering above the second filter layer 33. When the airflow passes through the first filter layer 34, the first filter layer 34 initially filters out the particulate impurities it contains. The second filter layer 33 further filters out the particulate matter in the airflow and then delivers the airflow to the lower filter chamber 32. The airflow in the lower filter chamber 32 passes through the middle of the second filter layer 33 again... After filtration, the air enters the reverse filter cartridge 28. The airflow entering the reverse filter cartridge 28 passes through the reverse filter box 30 and enters the first metal heat exchange pipe 29. The airflow passes through the lower end of the first metal heat exchange pipe 29 and enters the lower end of the first chamber. The airflow inside the lower end of the first chamber enters through the lower end of the second metal heat exchange pipe 31 and then enters the interior of the air outlet box 25. The airflow entering the air outlet box 25 passes through the air inlet 18, the air drying pipe 17, and the air outlet 19 in sequence and is blown onto the side of the workpiece 15 to be sprayed by the spray gun 9, so as to air dry the surface of the workpiece 15.

[0046] The second rotating arm 8 has a channel inside. One end of the channel is connected to the connecting pipe 11, and the other end of the channel is connected to the interior of the U-shaped mounting groove 10. A spray gun 9 is installed at the end of the U-shaped mounting groove 10 away from the first rotating arm 6. The spray gun 9 is connected to the end of the U-shaped mounting groove 10 that is connected to the channel through a flexible hose.

[0047] In the device, the hose is not shown in the figure. The mounting base of the spray gun 9 is installed on the U-shaped mounting groove 10, which facilitates disassembly and replacement, and makes it easy to use different models of spray guns 9.

[0048] The housing 20 has a first chamber, a second chamber and a third chamber arranged in sequence. The first chamber is close to the air outlet 25 and the third chamber is close to the air inlet 23. A turbine housing 21 is fixedly installed in the middle of the second chamber. A fourth motor 22 is installed on the turbine housing 21. A turbine is installed on the shaft of the fourth motor 22. One end of the turbine housing 21 is open and communicates with the third chamber. The other end of the turbine housing 21 is also open and communicates with the first chamber.

[0049] The fourth motor 22 and the turbine are each set on both sides of the second chamber, ensuring that there is a spare turbine. This avoids the situation where the other turbine cannot work properly due to too many particles blocking it. Moreover, when both turbines are turned on at the same time, the drying efficiency and the gas purification efficiency can be increased.

[0050] The third chamber contains the first filter layer 34.

[0051] It should be noted that both the first filter layer 34 and the second filter layer 33 can be composite filter layers such as PP cotton layer, filter cotton layer and activated carbon layer to fully purify the gas, which is beneficial to the purification and treatment of particulate gas and harmful gas generated during the spraying process.

[0052] A second filter layer 33 is fixedly installed in the first chamber. The lower part of the second filter layer 33 and the inner wall of the first chamber form a lower filter chamber 32. A reverse filter cylinder 28 is fixedly installed on the upper surface of the second filter layer 33. The lower end of the reverse filter cylinder 28 is open.

[0053] It should be noted that after the reverse filter cartridge 28 and the second filter layer 33 are combined, the gas can pass through the second filter layer 33 for secondary filtration from top to bottom and then pass through the purification path from bottom to top again to perform a third purification of the gas using the same set of second filter layers 33. Furthermore, the gas is more likely to detach particulate matter as it moves from bottom to top, which increases the purification effect of the gas.

[0054] The upper end of the reverse filter cartridge 28 is integrally provided with a reverse filter box 30, which is connected to the first metal heat exchange pipe 29. The lower end of the first metal heat exchange pipe 29 is connected to the lower end of the first chamber.

The upper end of the second metal heat exchange pipe 31 is connected to the interior of the air outlet box 25, and the lower end of the second metal heat exchange pipe 31 is connected to the lower end of the first chamber.

[0055] Furthermore, the gas passes evenly through the first metal heat exchange pipe 29 and the second metal heat exchange pipe 31, and can be cooled down so that the wind force used to dry the surface of the workpiece 15 to be sprayed maintains a suitable temperature, and there will be no phenomenon of high temperature baking that causes the powder material on the surface of the workpiece 15 to be sprayed to fall off. This maintains the purpose of low temperature drying and makes full use of the wind force during gas purification.

[0056] When the fourth motor 22 drives the turbine to rotate, it generates wind. The wind passes through the intake port 23, the first filter layer 34, and the turbine housing 21 in sequence and enters the upper part of the second filter layer 33. The second filter layer 33 filters out the particulate matter in the wind and then delivers the wind to the lower filter chamber 32. The wind in the lower filter chamber 32 is filtered again at the middle position of the second filter layer 33 and then enters the reverse filter cylinder 28. The wind entering the reverse filter cylinder 28 passes through the reverse filter box 30 and enters the first metal heat exchange pipe 29. The wind passes through the lower end of the first metal heat exchange pipe 29 and enters the lower end of the first chamber. The wind inside the lower end of the first chamber enters through the lower end of the second metal heat exchange pipe 31 and then enters the interior of the exhaust box 25.

[0057] The air entering the air box 25 passes through the air inlet 18, the air drying pipe 17, and the air outlet 19 in sequence, and is blown to the side of the workpiece 15 to be sprayed by the spray gun 9.

[0058] In the device, the connecting pipe 11 is installed on the first rotating arm 6 by the clamp 12 for easy arrangement. The first motor 2 can drive the rotating seat 3 and the above structures to rotate, so as to realize the purpose of the spray gun 9 rotating in the horizontal plane around the axis of the first motor 2. The second motor 5 can control the rotation of the first rotating arm 6, and the third motor 7 can control the rotation of the second rotating arm 8, thereby adjusting the height and tilt angle of the spray gun 9, which is convenient to use.

[0059] An alarm 24 is installed on the turbine housing 21 to monitor for material blockage inside.

[0060] When the alarm 24 sounds, it allows people to promptly clear the blockage in the turbine housing 21.
