Description

Technical Field

[0001] The utility model relates to the technical field of spray painting workshops, in particular to a compressed air supply system for a spray painting robot. Background Art

[0002] The automobile spray painting production line belongs to continuous flow operation. Compressed air, as the main energy medium for the spray painting robot, provides continuous power for it. The spray painting robot is extremely sensitive to the quality and pressure of compressed air. If the quality of compressed air is unqualified or the pressure fluctuates greatly, the spray painting robot will stop working, thus affecting the normal operation of the entire production line.

[0003] At present, most automobile factories adopt the mode of a centralized compressed air station to supply gas sources to multiple production workshops at the same time. Generally, the requirements for the quality and pressure of compressed air used by spray painting robots are higher than those of other workshops in the factory. To meet the needs of spray painting robots, the quality and pressure of the compressed air in the whole factory are uniformly increased, resulting in a great waste of production energy.

[0004] In the related art, the technical problem of waste of production energy caused by uniformly increasing the quality and pressure of compressed air due to different gas use qualities in different workshops has not been effectively solved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a compressed air supply system for a spray painting robot to solve the problem of waste of production energy caused by uniformly increasing the quality and pressure of compressed air due to different gas use qualities in different workshops in the related art.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A compressed air supply system for a spray painting robot includes a filtering component and a jetting component. The filtering component is connected to a ring-shaped main pipe, and at least one jetting component is connected to the ring-shaped main pipe; the filtering component includes a compressed air filter and a pressure gauge, and the jetting component includes a compressed air pressure buffer tank.

[0008] It is further set that: a manual ball valve is arranged at each of the air inlet and air outlet of the filtering component.

[0015] It is further set that: the annular main pipe is connected to a water collection and drainage device.

[0016] It is further set that: valves are connected to both ends of the water collection and drainage device; an electronic liquid level drain valve is integrated in the water collection and drainage device.

[0017] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0018] In the present utility model, in order to improve system stability, protect equipment and improve production efficiency, a number of designs are adopted. First of all, the air jet assembly is connected to the annular main pipe through the robot air supply branch pipe, and manual ball valves and a compressed air pressure buffer tank are arranged on the branch. The manual ball valve is convenient for controlling the air flow, while the pressure buffer tank effectively reduces the impact of a large amount of air use conditions on the pipe network load, reduces the air supply pressure fluctuation, and protects the robot equipment. In addition, the electronic liquid level drain valve integrated at the bottom of the buffer tank automatically drains water to keep the compressed air dry.

[0019] A water collection and drainage device is installed at the end of the annular main pipe.

[0029] Embodiment

[0030] Refer to Figures 1-3 , a compressed air supply system for a painting robot disclosed in the present utility model, which includes: a filtering assembly 10 and an air jetting assembly 11. The filtering assembly 10 is connected to a circular main pipe 5, and at least one air jetting assembly 11 is connected to the circular main pipe 5; the filtering assembly 10 includes a compressed air filter 3 and a pressure gauge 2, and the air jetting assembly 11 includes a compressed air pressure buffer tank 7.

[0031] Specifically, a compressed air filter 3 is provided at the air inlet of the filtering assembly 10. The oil and dust removal accuracy of the compressed air filter 3 is selected to meet the 1st level accuracy requirement of the national compressed air cleanliness specification, reducing the impact of dust and oil in the front-end compressed air pipeline on the robot. The housing material of the precision filter is selected as stainless steel or aluminum alloy.

[0032] The circular main pipe 5 is designed as a circular pipe network, which can effectively reduce the mutual influence of pressure fluctuations between different devices, and at the same time can ensure the gas supply stability of the devices and a high failure protection rate. The pipeline material can be selected as stainless steel or aluminum alloy, which can reduce the pressure loss of compressed air flow while ensuring the cleanliness of the pipeline.

[0033] By providing a compressed air filter 3 that meets the national 1st level accuracy requirement at the air inlet of the filtering assembly 10, the dust and oil in the front-end compressed air pipeline are effectively removed, significantly improving the quality of the compressed air supplied to end devices such as painting robots. This helps to reduce the pollution and damage to the precision components of the robot caused by dust and oil, and improves the operation stability and service life of the device. The design of the circular main pipe 5 enables the compressed air to flow more effectively balance and reduce the pressure fluctuations caused by changes in gas consumption between different devices when flowing in the pipe network. This design not only improves the gas supply stability, but also enhances the system's ability to respond to sudden failures, reducing the risk of production interruption caused by unstable pressure.

[0034] The compressed air filter 3 is used to ensure the quality requirements of the compressed air for the jet component 11. The air pressure buffer tank 7 for compressed air is used to ensure the stable air supply pressure of the end equipment, greatly reducing the overall compressed air supply pressure and quality in the automobile factory, saving a large amount of investment and later operation costs, and having high economic benefits.

[0035] It is further set that: a manual ball valve 1 is provided at each of the air inlet and the air outlet of the filter component 10. A pressure gauge 2 and a compressed air filter 3 are provided between the two manual ball valves 1, and the pressure gauge 2 is close to the manual ball valve 1 at the air inlet.

[0036] Specifically, the manual ball valves 1 at the air inlet and the air outlet allow the operator to flexibly open or close the filter component 10 according to actual needs, thereby controlling the flow of compressed air. This design is particularly important when maintenance, repair or replacement of the filter is required, as it can conveniently isolate the filter component 10 without affecting other parts of the entire compressed air system. The pressure gauge 2, which is close to the manual ball valve 1 at the air inlet, can display the compressed air pressure at the inlet of the filter component 10 in real time and accurately. This is crucial for monitoring the working state of the filter component 10, promptly detecting and handling potential pressure problems. At the same time, the reading of the pressure gauge 2 can also be used as a basis for adjusting and optimizing the parameters of the compressed air system. By precisely controlling the flow and pressure of the compressed air and combining with the efficient filtering effect, this design can significantly improve the stability and reliability of the compressed air system. This helps to reduce the risks of production interruption and equipment damage caused by problems with the quality of compressed air or pressure fluctuations.

[0037] It is further set that: a sampling branch is connected between the compressed air filter 3 and the manual ball valve 1 at the air outlet, and a purging sampling port 4 is connected to the sampling branch.

[0038] Specifically, a purging and sampling port 4 is provided at the rear end of the compressed air filter 3, facilitating the purging and sampling of the entire branch pipe network. The diameter of the purging and sampling port 4 can be selected as DN15. The design of the purging and sampling port 4 makes the purging of the entire branch pipe network more convenient. When it is necessary to clean impurities and residues in the pipe network or perform regular maintenance, high-pressure gas or fluid can be introduced through the purging and sampling port 4 to thoroughly flush and clean the pipe network, thus ensuring the cleanliness and smoothness of the pipe network. The setting of the sampling branch and the purging and sampling port 4 also facilitates the sampling and detection of the entire compressed air system. Without interrupting the normal operation of the system, operators can obtain compressed air samples through the sampling branch for subsequent quality analysis and detection. This helps to promptly detect and handle problems such as impurities and oil content in the compressed air, ensuring that the quality of the compressed air supplied to downstream equipment meets the requirements. This design improves the maintenance efficiency of the compressed air system. Through the convenient purging and sampling functions, operators can more quickly locate and solve potential problems in the system, reducing production interruptions and losses caused by system failures. At the same time, regular sampling and detection also help to promptly detect and prevent potential quality problems, improving the stability and reliability of the system.

[0039] It is further set that: the jet component 11 is connected to the annular main pipe 5 through the robot air supply branch pipe 6. A manual ball valve 1 is provided at each of the inlet and outlet of the robot air supply branch pipe 6. A compressed air pressure buffer tank 7 is connected between the two manual ball valves 1. An electronic liquid level drain valve is provided at the bottom of the compressed air pressure buffer tank 7. The outlet of the robot air supply branch pipe 6 is connected to the robot equipment 8.

[0040] Specifically, a compressed air pressure buffer tank 7 is provided on the robot air supply branch, which can effectively reduce the impact of a large amount of gas-consuming conditions such as the robot's purging cup on the load of the air supply pipe network, thereby reducing the impact of the air supply pressure fluctuation on the robot equipment 8. The compressed air pressure buffer tank 7 is installed by hoisting and under the process platform, saving floor space. An electronic liquid level drain valve is provided at the bottom of the compressed air pressure buffer tank 7, which can reduce the moisture contained in the compressed air while stabilizing the pressure.

[0041] The setting of the compressed air pressure buffer tank 7 is the core of this design. It can effectively absorb and store compressed air. When the robot is in operation under conditions of large air consumption such as purging the rotary cup, it stabilizes the pressure of the gas supply pipeline by releasing the stored compressed air, thereby reducing the impact of gas supply pressure fluctuations on the robot device 8. This helps to ensure the stable operation of the robot device 8 and avoid performance degradation or failures caused by pressure fluctuations. By setting two manual ball valves 1 on the robot gas supply branch, the flow of compressed air can be conveniently controlled. When maintenance, repair, or component replacement is required, the corresponding manual ball valve 1 can be closed to isolate the robot gas supply branch without affecting the normal operation of other devices on the annular main pipe 5. This design improves the flexibility and stability of the gas supply system. The electronic liquid level drain valve installed at the bottom of the compressed air pressure buffer tank 7 can automatically drain the moisture in the compressed air. Moisture is a common impurity in compressed air. If its content is too high, it will cause corrosion and damage to the robot device 8. By draining the moisture in a timely manner, the dryness and purity of the compressed air can be maintained, and the service life of the robot device 8 can be extended.

[0042] It is further set that: the annular main pipe 5 is connected with a water collection and drainage device 9. Valves are connected to both ends of the water collection and drainage device 9; an electronic liquid level drain valve is integrated in the water collection and drainage device 9.

[0043] Specifically, a water collection and drainage device 9 is arranged at the end of the annular main pipe 5, and an electronic liquid level drain valve is integrated in the centralized drainage device, so that the moisture precipitated in the compressed air can be regularly discharged, reducing the impact of the water content of the compressed air on production. The water collection and drainage device 9 can capture and collect the moisture precipitated in the compressed air. By integrating the electronic liquid level drain valve, these moisture can be automatically discharged regularly, thus significantly reducing the water content in the compressed air. This is crucial for maintaining the dryness and purity of the compressed air system and helps to prevent equipment corrosion, performance degradation, or failures caused by excessive moisture.

[0044] The working principle and beneficial effects of the present utility model are as follows:

[0045] In the present utility model, in order to improve system stability, protect equipment, and improve production efficiency, a number of designs are adopted. First, the jet component 11 is connected to the annular main pipe 5 through the robot gas supply branch pipe 6, and manual ball valves 1 and a compressed air pressure buffer tank 7 are arranged on the branch. The manual ball valve 1 facilitates the control of the air flow, while the pressure buffer tank effectively reduces the impact of large air consumption conditions on the network load, reduces the gas supply pressure fluctuations, and protects the robot device 8. In addition, the electronic liquid level drain valve integrated at the bottom of the buffer tank automatically drains the moisture, maintaining the dryness of the compressed air.

[0046] A water collector and drainer 9 is installed at the end of the annular main pipe 5. This device integrates an electronic liquid level drain valve, which regularly and automatically discharges the moisture separated from the compressed air, further reducing the impact of moisture content on production. This design not only improves product quality and production efficiency but also extends the equipment life and reduces corrosion and failures caused by moisture.

[0047] Through reasonable layout and component configuration, the entire system realizes efficient and stable compressed air supply. The flexibility of the manual ball valve 1, the buffering effect of the pressure buffer tank, and the automatic drainage function of the water collector and drainer 9 together constitute an efficient and reliable compressed air treatment system. These designs not only improve the automation level of the system but also reduce the operating cost and maintenance difficulty, providing strong support for industrial production.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
