Description

Technical Field

[0001] This application relates to the field of industrial spray painting technology, specifically to a robotic automatic spray painting method and a dry spray booth. Background Technology

[0002] Traditional spray booths mostly employ wet spraying methods, such as water vortex and water curtain spray booths. Their basic principle is to capture and wash away paint mist particles in the air using a circulating water system. Specifically, air containing paint mist is guided by a fan to the liquid surface or water curtain at the bottom of the spray booth. The paint mist is washed away and condensed during contact with the water, thus separating from the air. While this method has a certain paint mist capture efficiency, its inherent drawbacks are significant: First, the process generates a large amount of wastewater containing paint residue and chemical agents. This wastewater must undergo complex physical and chemical treatment before it can be discharged or recycled, which not only increases the cost of a large water treatment system and corresponding chemicals but also poses a serious risk of secondary environmental pollution. Second, wet spray booths have high overall energy consumption, as their air supply, exhaust, and water circulation systems all need to operate continuously, resulting in significant energy waste.

[0003] With increasingly stringent environmental protection requirements and a growing emphasis on energy conservation and emission reduction, dry spray booth technology has emerged and developed to some extent. Dry spray booths eliminate water treatment methods, instead employing multi-layered dry filter materials to directly filter and adsorb paint mist. Compared to wet treatment, its advantage lies in eliminating the need for water, fundamentally preventing wastewater generation, and simplifying the system structure. Existing dry spray booths typically adopt a linear model of "air supply, filtration, and direct discharge to exhaust gas treatment." However, in practical applications, especially in production lines with both manual pre-spraying stations and robotic main spraying stations, this design reveals new problems: each spraying station has its own independent air supply and exhaust system, resulting in a simple superposition of fan power, a large total installed power, and high operating energy consumption; simultaneously, the air volume discharged to the terminal exhaust gas treatment system is huge, but the concentration of organic solvents in the paint mist is relatively low. This causes the exhaust gas treatment system to operate under low concentration and high air volume conditions, resulting in low treatment efficiency and high energy consumption costs per unit of exhaust gas, failing to fully realize the energy-saving potential of dry technology.

[0004] Furthermore, existing dry spray booths have numerous shortcomings in structural design and safety protection: First, their bottom filtration system is typically covered with a full grating panel, with only a small area below the grating containing dripping paint residue. When cleaning accumulated waste paint, a large area of ​​the grating panel must be completely dismantled, a cumbersome and time-consuming process that severely impacts equipment maintenance convenience and production line uptime. Second, existing designs often have serious fire safety hazards. The spray painting area has a high concentration of volatile organic compounds, making it an explosive hazardous environment. However, current technologies either lack fire dampers or only have simple ones at the main duct outlet, and generally lack comprehensive fire alarm and automatic fire extinguishing systems. Once a local fire occurs, flames and high-temperature smoke can easily spread rapidly through the ducts to the entire spray booth and even adjacent factory areas. The limited number of fire sprinklers cannot provide rapid and effective fire extinguishing, and the lack of a fire alarm system leads to delayed detection of hazards, potentially causing significant safety accidents and property damage.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present invention, and therefore may include information that does not constitute prior art. Application content

[0006] To address the shortcomings of existing technologies, this application discloses a robotic automatic painting method and a dry spray booth, which can solve the aforementioned problems. Specifically, it is a novel dry spray booth system that achieves true energy saving and emission reduction, convenient maintenance, and improved inherent safety while ensuring painting quality and adaptability to robotic operations.

[0007] To achieve the above objectives, this application provides the following technical solution: The robotic automatic painting method includes the following steps: Air circulation and exhaust gas treatment: Fresh air is supplied from the manual spray booth to the robotic spray booth, and the high-concentration exhaust gas discharged from the robotic spray booth is filtered and monitored. The robot automatically sprays paint, reads workpiece information and sprays paint in the painting area, monitors VOCs concentration and increases exhaust volume when it exceeds the standard; Clean up the waste paint and check the plastic film on the baffle in the sinking area. If the filter media is clogged or the efficiency is reduced, replace it with a new filter media. Firefighting measures include real-time environmental monitoring; if the temperature exceeds the limit or smoke is generated, dual fire prevention actions are triggered. The system was shut down to complete the final steps. According to the system shutdown command, painting, air circulation, and monitoring were stopped.

[0008] The preferred technical solution includes the following steps: The robotic spray booth enters operation mode, triggering air circulation to deliver fresh air to the manual spray booth; The air in the manual spray booth is filtered twice to deliver clean air to the robotic spray booth. The robot filters the paint mist / exhaust gas generated during painting in the paint booth, and treats and filters the high-concentration exhaust gas. Real-time monitoring of waste gas treatment energy consumption, recording of energy consumption data, and comparison with traditional solutions to obtain energy saving rates.

[0009] The preferred technical solution includes the following steps: Trigger the painting command, accurately position the workpiece in the painting area, read the workpiece information, start the painting operation according to the preset parameters, and cover all surfaces of the workpiece along the planned path; Real-time monitoring; if paint film defects are found, adjust the painting speed / paint volume parameters; if an abnormality occurs, suspend the operation and trigger a local alarm; if the VOCs concentration exceeds the standard, increase the exhaust volume. Once the painting operation is complete, the painting stops, and the painted workpiece leaves the robot painting booth to proceed to the next process.

[0010] The preferred technical solution includes the following steps: Once the robotic paint booth has completed painting the workpiece or reached the preset cleaning cycle, it will stop air circulation and ventilate. Inspect the plastic film on the partition in the sunken area, remove the plastic film with attached waste paint, clean the residual waste paint on the surface of the partition, and lay a new plastic film to cover the surface of the partition. If the filter media becomes clogged or its efficiency decreases, replace it with new filter media, and the robot spray booth will return to a standby state.

[0011] The preferred technical solution includes the following steps: The system monitors the environment in real time and triggers a fire alarm if the temperature exceeds the standard or smoke is produced. Triggering dual fire prevention actions, shutting off fire dampers and air ducts in the corresponding areas, and starting fire suppression spraying in robot or manual paint booths, while simultaneously stopping all equipment; Investigate the cause of the fire, repair faulty components, and restart the air circulation and robot.

[0012] The preferred technical solution includes the following steps: Issue a system shutdown command to stop painting, air circulation, and monitoring, and check the status inside the paint booth; If there is paint mist residue in the spray booth or paint residue on the equipment surface, clean the robot nozzle and / or the inner wall of the spray booth. If there is no paint mist residue in the spray booth and no paint residue on the equipment surface, turn off all main power switches and record production data.

[0013] In addition, this application also discloses a dry spray booth, which includes: A circulating air conditioning and exhaust gas treatment system is used to supply fresh air from the manual spray booth to the robotic spray booth, filter the high-concentration exhaust gas discharged from the robotic spray booth, and monitor it.

If the temperature exceeds the standard or smoke is generated, it will trigger a dual fire prevention action.

[0014] In a preferred embodiment, the fire alarm system includes a fire damper, a fire sprinkler head, and a temperature sensor.

[0015] This application discloses a robotic automatic painting method and a dry spray booth, which have the following advantages: The dry spray booth described in this application differs from traditional spray booths that rely on wet methods such as water curtains and water swirls to treat paint mist. This system employs a physical filtration principle, with its core being a multi-layered, high-efficiency dry filtration device. Paint mist generated during spraying is guided by a fan through these filtration layers sequentially, where paint mist particles are captured and adsorbed at each stage. Since the entire process requires no water, it fundamentally eliminates the generation of wastewater containing paint residue and chemical agents, avoiding subsequent complex wastewater treatment processes and their potential environmental pollution risks. Simultaneously, the gas purified by the high-efficiency filtration system exhibits significantly reduced levels of paint mist and volatile organic compounds, effectively minimizing atmospheric pollution before emission. Throughout the process, the system maintains a slightly negative pressure environment within the spray booth, effectively preventing the leakage of harmful exhaust gases. Furthermore, the system monitors and records the energy consumption of the fan and exhaust gas treatment equipment in real time, continuously optimizing its operation through comparison with traditional solutions to ensure significant energy savings while achieving compliant exhaust emissions.

Specific implementation manners

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of this application.

[0020] All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making any creative efforts shall fall within the scope of protection of this application.

[0021] Embodiment 1 Refer to the appendix Figure 1-6 , the robot automatic painting method described in this application includes the following steps.

[0022] System startup and preparation stage. This stage is the beginning of the robot automatic painting operation, aiming to ensure that all equipment is in normal condition and the environment is ready. The whole process starts with the startup of the production task, and then a comprehensive equipment initialization inspection is carried out. This includes: confirming that the operation of the fan and the status of the air duct valve meet the specifications. Checking whether the filtration system is complete and its efficiency meets the standard. Testing the alarm function of the fire protection system, the flexibility of the fire damper, and the normal supply of sprinkler water. Calibrating the positioning accuracy of the robot and confirming that its painting parameter settings are correct. A unified pass / fail determination will be made for all inspection items. If any item fails, the process will transfer to the fault handling link, that is, locating the faulty equipment and performing manual maintenance or replacing components until all equipment inspections are confirmed to be qualified. When all equipment is confirmed to be normal, the system starts to prepare for work transportation: starting the transportation system to transport the structural parts to be painted to the designated workstations in the spraying room. Finally, closing and sealing the pedestrian door of the spraying room to prepare for the subsequent automatic painting operation in a closed space.

[0023] The air circulation and exhaust gas treatment stage is the core of achieving high efficiency, energy saving, and environmental compliance in dry spray booths. When the robotic spray booth begins operation, the entire air circulation and exhaust gas treatment system is activated, creating a sophisticated air circulation loop: First, the fresh air conditioning system starts, providing fresh air to the adjacent manual spray booth. Air from the manual spray booth undergoes preliminary purification via a permeation filter before being sent to the circulating air conditioning system. This system performs secondary filtration, deeply removing harmful gases and residual paint mist to meet cleanliness standards. Finally, this purified clean air is delivered to the robotic spray booth, providing a high-quality air supply for high-precision robotic spray painting operations.

[0024] Meanwhile, the exhaust gas treatment process operates efficiently: paint mist and exhaust gases generated inside the robotic spray booth are first captured and treated by a filter device at the bottom of the booth. Subsequently, the exhaust fan sends this pre-concentrated exhaust gas into the terminal exhaust gas treatment system, significantly improving the efficiency of exhaust gas treatment. Throughout the process, the system maintains a slightly negative pressure environment inside the spray booth, effectively preventing the leakage of harmful exhaust gases. Simultaneously, the system monitors and records the energy consumption of the fans and exhaust gas treatment equipment in real time, continuously optimizing its operation through comparison with traditional solutions to ensure significant energy savings while achieving compliant exhaust gas emissions.

[0025] The automated robotic painting stage is the core execution phase of the entire paint booth process, achieving highly automated and precise painting. The entire process begins with a linked start signal: once the air circulation system confirms readiness, it automatically triggers the robot's painting command. Subsequently, the conveyor system precisely transports the workpiece to the painting area. The robot reads the workpiece's identification information and uses this information to call up preset painting programs and 3D model data, ensuring personalized and accurate operation. During the actual painting process, the robot uses the trajectory provided by the 3D sensing system to uniformly and precisely paint all surfaces of the workpiece according to an optimized path. To ensure work quality and safety, a real-time monitoring system operates throughout the process. It dynamically responds to three main situations: for quality defects, the system automatically adjusts the robot's painting speed or paint parameters; if an equipment malfunction is detected, the operation is immediately paused and a local alarm is issued; if environmental sensors detect excessive VOC or paint mist concentration, the system automatically increases ventilation to ensure a safe working environment. After the painting operation is completed, the robot automatically stops and returns to the standby position. Finally, the conveyor system moves the painted workpiece out of the spray booth and to the next process, such as the drying oven. This process fully demonstrates the efficiency and reliability of automated and intelligent production in quality control, fault response, and environmental management.

[0026] Waste Paint Cleanup Phase. This phase is the core of spray booth maintenance, aiming to quickly restore the spray booth's operational capacity by cleaning solid waste paint generated during spraying in a convenient and efficient manner. Cleanup is triggered in two situations: first, after completing a batch of workpieces; and second, upon reaching a preset cleanup cycle. The cleanup process begins with safety preparation: first, the air circulation system is stopped, and the spray booth door is opened for ventilation. Then, workers locate the specially designed waste paint collection area, a partially sunken floor structure that replaces the traditional full-coverage grating. Its core lies in an innovative waste paint capture solution: plastic films are pre-laid on the partitions within the sunken area, and the overspray generated during spraying adheres directly to these films. During cleanup, workers simply remove the entire plastic film covered in waste paint. This method eliminates the need to disassemble any hardware partitions or gratings, greatly reducing disassembly steps and labor intensity. After removing the old film, a small amount of residue is cleaned up, and a new plastic film is laid, completing the reset of the collection surface.

[0027] Simultaneously, the system checks the filter media of the paint mist filtration device. If clogging or decreased efficiency is detected, it is replaced immediately to ensure filtration performance. Finally, the spray booth door is closed. At this point, the waste paint cleanup is complete, and the entire spray booth is ready for operation, prepared for the next production task. This design significantly improves maintenance efficiency and highlights the concept of convenient maintenance.

[0028] Fire Emergency Response Phase. This phase establishes a complete fire safety protection system, encompassing monitoring, alarm systems, and coordinated firefighting, ensuring timely response to fires at any time during sprinkler room operation. The entire process begins with 24 / 7 real-time monitoring, continuously monitoring environmental conditions through temperature and smoke sensors. Upon detecting abnormal temperatures or smoke, the system immediately escalates its response: First, it simultaneously triggers audible and visual alarms and remote notifications, ensuring that on-site personnel and firefighters receive alerts simultaneously. Almost simultaneously, an emergency shutdown procedure is executed: all operating equipment is stopped and power is cut off to prevent the danger from escalating. Critical dual fire dampers activate immediately, effectively blocking the path of fire spread through ductwork. Subsequently, the precision sprinkler system is activated, spraying water only on the specific functional area where the fire occurred, minimizing water damage and impact on other equipment. After the open flames are extinguished, the process enters the post-fire handling phase: firefighters arrive to confirm the firefighting results, then investigate the cause of the fire, and finally repair and replace faulty equipment and consumables to restore the system to a safe state. This process emphasizes the concept of dual protection, achieving a combination of rapid response and precise handling through equipment linkage and zoned fire suppression.

[0029] System shutdown and cleanup phase. This phase is the standard shutdown procedure at the end of each day or production cycle of the paint booth, designed to ensure equipment safety, environmental cleanliness, and preparation for the next startup. Once it is confirmed that all production tasks for the day have been completed and there are no more workpieces to be painted, the system will officially issue a shutdown command. The shutdown process follows a strict sequence: First, the core robotic painting system is stopped, the paint supply is shut off, and the robotic arm is retracted to its safe origin position. Next, the air circulation system is shut down in reverse order: the fresh air conditioning, the recirculating air conditioning, and finally the exhaust fan is turned off to ensure complete exhaust of waste gas. Simultaneously, the fire suppression system is switched from real-time monitoring mode during operation to a low-power standby protection mode to maintain constant safety. After equipment shutdown, critical on-site inspections and cleaning are performed: personnel must confirm that residual paint mist in the paint booth has been completely emptied and check for paint residue on the robotic nozzles and the inner walls of the equipment. If necessary, a thorough cleaning is performed using a specialized cleaning agent. Finally, administrative and safety cleanup is conducted: the production data for the shift is recorded for analysis. Finally, the main power supply was cut off and the paint booth was locked, marking the successful completion of the entire system shutdown and finalization work. This process ensures equipment maintenance and the traceability of production data, achieving a closed-loop management system.

[0030] Example 2 The dry spray booth described in this application differs from traditional spray booths that rely on wet methods such as water curtains and water swirls to treat paint mist. This system employs a physical filtration principle, with its core being a multi-layered, high-efficiency dry filtration device. Paint mist generated during spraying is guided by a fan through these filtration layers sequentially, where paint mist particles are captured and adsorbed at each stage. Since the entire process requires no water, the generation of wastewater containing paint residue and chemical agents is fundamentally eliminated, avoiding subsequent complex wastewater treatment processes and their potential environmental pollution risks. Simultaneously, the gas purified by the high-efficiency filtration system exhibits significantly reduced levels of paint mist and volatile organic compounds, effectively minimizing atmospheric pollution before emission.

[0031] To further achieve energy conservation and emission reduction, this system has optimized the airflow layout for production lines that include both manual and robotic painting stations. (See attached document.) Figure 7 The exhaust vent of the manual spray painting booth 1 is connected to its own primary filtration system via a duct. The exhaust vent of the primary filtration system is not directly discharged to the atmosphere or the waste gas treatment end, but is connected to the inlet of a circulating air conditioning unit 4 via a circulating air duct 3. This circulating air conditioning unit 4 regulates the temperature and humidity of the pre-purified gas from the manual spray painting booth and performs secondary filtration before sending it as makeup air to the robotic spray painting booth 5. The robotic spray painting booth 5 has its own independent high-efficiency filtration system 6, which performs final purification of the gas after the spray painting operation before it is sent to the terminal waste gas treatment system 8 by the main exhaust fan 7.

[0032] This air circulation design eliminates the need for a separate exhaust fan in the manual spray painting booth; the system only requires one main exhaust fan 7, directly reducing the installed power and operating energy consumption of the fan. Since the gas from the manual spray painting booth is reintroduced into the robotic spray painting booth, the total air volume entering the terminal exhaust gas treatment system 8 is reduced. Overall energy consumption can be reduced to about half of the original design, thus achieving significant energy saving and emission reduction.

[0033] This embodiment focuses on improving the waste paint collection structure at the bottom of the spray booth, aiming to enhance maintenance convenience. See Appendix. Figure 7 Below the robot spray booth 5, at least one sunken collection trough 9 is installed to cover the robot's activity area and the main paint mist settling area. The top opening of the collection trough 9 is flush with the floor of the spray booth and can be selectively covered with a grating plate. At the bottom of the sunken collection trough 9, one or more interlocking partitions are laid to collect dripping and settling waste paint. For easy cleaning, a replaceable plastic film is laid on the upper surface of the partitions.

[0034] When accumulated waste paint needs to be cleaned, maintenance personnel do not need to dismantle heavy gratings or partitions. They only need to open the access door of the sunken collection tank 9, roll up or remove the plastic film covered with waste paint, and replace it with a new film. This structure simplifies the originally time-consuming and laborious cleaning work into a quick film replacement operation, greatly reducing the maintenance downtime of the paint booth and allowing more time to be devoted to production, effectively improving the overall capacity of the production line.

[0035] This embodiment details the fire safety design of the spray booth. Given that the spray booth is an explosive hazardous environment, to effectively prevent the spread of fire, this embodiment sets up multiple fire barriers at key nodes in the system's airflow. Specifically, fire dampers 13 are installed on the air ducts connecting different functional areas. Each fire damper 13 has at least two independent closing triggering mechanisms: passive temperature triggering, where the fuse on the fire damper 13 melts when the airflow temperature in the duct rises to a set operating temperature, and the valve automatically closes under spring action, cutting off the airflow. Active signal linkage, where the fire damper is either electric or pneumatic, and its control signal line is linked to a fire alarm system installed in the spray booth. This fire alarm system includes distributed temperature sensors and / or smoke detectors. Once any detector detects a fire alarm signal, the fire alarm system immediately sends a closing command to all linked fire dampers, causing them to actively close. This forms an effective fire separation before flames and high-temperature smoke spread through the air ducts, greatly improving the ability to prevent the spread of fire.

[0036] Furthermore, to achieve early warning and automatic fire suppression, this embodiment evenly distributes a large number of fire sprinklers, temperature sensors, and smoke detectors on the ceiling of each functional area within the paint booth. These are all connected to the aforementioned fire alarm system. When a fire occurs, the system can: rapidly and automatically extinguish the fire (the glass bulbs of the fire sprinklers above the fire source rupture upon heating, automatically spraying water to extinguish the fire); and provide immediate alarm (upon receiving a detector signal, the fire alarm system immediately issues an audible and visual alarm locally and can automatically send the fire alarm information to the factory fire control center or directly notify the fire department via the network, ensuring that relevant personnel are informed and can respond immediately, minimizing fire losses.
