Description

Technical Field

[0001] This application relates to the field of automated coating technology, and in particular to a cleaning device, control method and system for a rapid color change system. Background Technology

[0002] Currently, in the practical application of rapid color change systems, the cleaning process of pipelines and launch stations consumes a large amount of cleaning solvent. However, existing systems lack effective means to accurately measure the consumption of cleaning solvent, making it impossible to achieve real-time statistics on solvent usage, which significantly hinders the management of hazardous waste in the workshop. Furthermore, the judgment of the cleaning effect of rapid color change systems currently relies mainly on subjective evaluation by human visual inspection. This method lacks unified and quantifiable judgment standards, easily leading to extreme situations of over-cleaning or incomplete cleaning. For example, over-cleaning results in unnecessary solvent waste, increasing production costs and hazardous waste disposal pressure; incomplete cleaning leads to cross-contamination of paints, affecting the quality of subsequent sprayed products and increasing production costs. Moreover, the cleaning procedures of existing rapid color change systems are fixed in design, making the modification process cumbersome and complex. They cannot quickly adjust the cleaning strategy according to actual working conditions such as paint type and color change sequence, thus reducing the color change efficiency and process matching degree of the production line.

[0050] To make the purpose, technical solution, and advantages of this application clearer, the following will be described in conjunction with the appendix. Figures 1-3 This application will be described in further detail. It is obvious that the described embodiments are merely some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application.

[0051] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “said,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, and “multiple” generally includes at least two unless the context clearly indicates otherwise.

[0052] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0053] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.

[0054] like Figure 1The illustrated rapid color-changing system cleaning device includes:

[0055] The main oil supply equipment is used to supply paint and deliver it to the quick color change system;

[0056] The rapid color-changing system is used to transport the paint supplied by the main oil supply equipment to the target station, and then transport the paint from the target station to the spraying robot for spraying.

[0057] The rapid color-changing system includes: a launching station, a delivery pump, and a ball bearing tube;

[0058] The launching station is used to feed the internal ball along one end of the ball tube into the ball tube;

[0059] The delivery pump is used to deliver the paint supplied by the main oil supply equipment to the ball bearing tube, and to push the ball bearing in the ball bearing tube toward the target station by the paint; the delivery pump is connected to the launch station through the first pipeline; the launch station is connected to the ball bearing tube;

[0060] When the ball in the ball tube moves to the preset position of the target station, the ball tube connects with the target station, allowing the paint in the ball tube to flow into the target station, and under the action of the delivery pump, the paint is delivered to the spraying robot for spraying; wherein, the target station and the spraying robot are connected by a second pipe.

[0061] After the painting robot finishes painting, it drives the ball bearing at a preset position in the target station to move in the ball bearing tube through a high-pressure air source connected to the target station until it reaches the initial position of the launch station. During the ball bearing return process, the paint in the ball bearing tube is pushed to the launch station.

[0062] In this embodiment, the high-pressure pipeline connected to the high-pressure gas source is controlled to open or close via a pulse air valve.

[0063] Specifically, in this embodiment, a linked conveying structure of ball bearings and paint is used to drive the ball bearings within the ball bearing tube and trigger the connection of the passage within the target station, thereby achieving directional conveying of the paint and a fast color change response. After spraying, the ball bearings are driven to return through a high-pressure air source. During the return process, the ball bearings can physically scrape off and push the residual paint in the ball bearing tube to the launch station, thereby reducing paint residue in the pipeline and reducing the difficulty of subsequent cleaning processes. At the same time, the inner wall of the ball bearing tube is smooth and does not require separate cleaning. It can be kept clean by the physical action of the ball bearings alone. On this basis, the cleaning design strategy of separate pipelines improves the overall cleaning efficiency and reduces the consumption of cleaning solvents and the waste of paint.

[0064] In one specific embodiment, the main oil supply equipment includes at least:

[0065] A portable paint storage tank that stores a single color of paint.

[0066] The main oil supply pump, which is connected to the paint storage tank, is used to transport the single color paint in the paint storage tank to the delivery pump, and then the delivery pump delivers the single color paint to the ball bearing tube; wherein, the main oil supply pump is connected to the delivery pump through a third pipeline.

[0067] It should be noted that both the launch station and the painting robot are equipped with electrically controlled valve cores. When the cleaning program is started, the opening and closing status of each electrically controlled valve core is precisely controlled to seal and isolate the first, second, and third pipelines from the ball bearing pipe, the main oil supply equipment, and the non-cleaning section of the painting robot, so that each pipeline to be cleaned forms an independent cleaning flow channel, thereby completing the precise cleaning of the sub-pipes.

[0068] In one specific embodiment, the painting robot is equipped with a color-changing valve assembly;

[0069] The color-changing valve assembly includes:

[0070] The color-changing valve is configured to correspond to the number of different paint colors in the configuration.

[0071] Each color channel of the color-changing valve corresponds to a type of color paint, and the outlet of each color channel is connected to the corresponding nozzle through a corresponding pipe.

[0072] In one specific embodiment, each of the first, second, and third pipes is equipped with a set of cleaning components and a flow sensor; each set of cleaning components includes: a cleaning solvent valve for controlling the on / off state of the cleaning solvent pipeline, a cleaning air valve for controlling the on / off state of the high-pressure cleaning air path, and an electrically controlled valve for controlling the on / off state of the cleaning waste liquid pipeline; the cleaning waste liquid pipeline is connected to a waste liquid storage tank.

[0073] The flow sensors on the first, second, and third pipes respectively detect the flow rate of the cleaning solvent or paint in the corresponding pipes.

[0074] In this embodiment, the outlet end of the main oil supply pump is connected to one end of the third pipeline, the other end of the third pipeline is connected to the inlet end of the delivery pump, the outlet end of the delivery pump is connected to one end of the first pipeline, the other end of the first pipeline is connected to the launch station, and the other end of the launch station is connected to the ball bearing tube.

[0075] It is understood that this application independently configures cleaning components and flow sensors on the first, second, and third pipelines; through the cleaning solvent valve, cleaning air valve, and waste liquid electrically controlled valve of the cleaning components, the solvent supply, high-pressure air circuit on / off, and waste liquid discharge can be precisely controlled respectively, thereby realizing the individual control of cleaning solvent in each pipeline and centralized recovery of waste liquid, avoiding cross-contamination between pipelines; at the same time, the flow sensors in each pipeline can detect the flow rate of cleaning solvent or paint in real time, providing data support for adjusting solvent flow parameters and optimizing cleaning effect during the cleaning stage.

[0076] During operation: The rapid color-changing system uses a ball bearing and ball bearing tube to clamp the paint in the middle of the ball bearing tube. Through devices such as a delivery pump and a launch station, the required paint is delivered to the target station, thus providing paint for the painting robot. After the robot finishes painting, the ball bearing at the target station uses compressed air as power to push the remaining paint back to the launch station. The inner wall of the ball bearing tube is clean. Paint remains in the second pipe between the target station and the color-changing valve of the painting robot, and in the first pipe between the launch station and the delivery pump. To ensure the color difference of the next color paint, the remaining paint needs to be cleaned. The cleaning media are solvent and compressed air. This solves the technical problem of previous rapid color-changing systems that relied on visual judgment to determine whether the cleaning of the entire pipeline was thorough, resulting in over-cleaning or under-cleaning. The technical solution provided in this application can ensure the best cleaning effect with the minimum amount of solvent used.

[0077] On the other hand, this application provides a cleaning control method for a rapid color-changing system, applied to the aforementioned device; the method includes the following steps:

[0078] S1: In response to the spraying end command, start the pipeline cleaning function and generate the first control command;

[0079] S2: In response to the first control command, based on the type of paint to be cleaned and the sequence of processes in the current process, the cleaning parameters of three sets of cleaning components are obtained in advance; wherein, the cleaning parameters include at least: the solvent flow rate for cleaning the first pipe, the second pipe and the third pipe, and the preset time parameters and number of cycles corresponding to the cleaning solvent valve and the cleaning air valve for each cycle in each pipe; the sequence of processes includes: the paint switching order and interval between the current process and the next process;

[0080] S3: Based on the acquired cleaning parameters, a preset strategy is used to clean the first pipe, the second pipe, and the third pipe;

[0081] S4: When the cleaning is finished, collect the mixed waste liquid solvent from the corresponding pipeline for analysis. Based on the analysis results, optimize the cleaning parameters of the three sets of cleaning components.

[0082] It is understood that this application automatically initiates the cleaning function in response to the end of the spraying command, and pre-retrieves appropriate cleaning parameters based on the type of paint to be cleaned, the paint switching sequence, the interval time, and other process sequences, thereby achieving automated triggering of the cleaning process. It can also accurately match the initial cleaning strategy according to the characteristics of the paint and the production conditions, which greatly improves the cleaning response efficiency. Furthermore, by configuring cleaning parameters, such as multi-pipe solvent flow rate, valve time parameters and cycle number, and by executing sub-pipe cleaning through preset strategies, the standardization and executability of the cleaning operation are ensured. After cleaning, the cleaning parameters are dynamically optimized through waste liquid sampling and analysis results to continuously iterate and improve the cleaning effect and reduce solvent waste.

[0083] It should be noted that, based on the color paint switching sequence between the current process and the next process, differentiated cleaning parameters can be specified. This can prevent contamination of the next light-colored paint by strengthening cleaning when switching from dark to light colors, and can reduce excessive operation by simplifying cleaning when switching from light to dark colors. This ensures the cleaning effect from the root, while avoiding incomplete cleaning or waste of resources due to unreasonable parameter configuration.

[0084] It should be further noted that the interval duration refers to the waiting time from the completion of the current process (spraying and cleaning) to the start of the next process (introducing new paint) or the interval from the completion of cleaning to the delivery of new paint. In terms of design, the interval duration allows for prediction of the degree of curing of residual paint in the pipeline, enabling the pre-matching of more reasonable cleaning parameters and avoiding incomplete cleaning due to the curing of residual paint.

[0085] In one specific embodiment, step S3 specifically includes:

[0086] The preset strategy includes:

[0087] Simultaneously, the cleaning components on the first, second, and third pipelines are started and run according to the corresponding cleaning parameters until the cumulative cleaning time reaches the first time setting value. Then, the cleaning solvent valves of all cleaning components are closed and the cleaning air valves of all pipelines are opened to continue running for the second time setting value, and then all cleaning air valves are closed. In each cycle, the cleaning solvent valves and cleaning air valves are opened in an alternating manner.

[0088] It is understood that this application achieves parallel cleaning of multiple pipelines by simultaneously activating the cleaning components of three pipelines and operating them based on corresponding cleaning parameters, thereby shortening the overall cleaning time and improving the color change efficiency of the production line. When the cumulative cleaning time reaches the first set time value, the cleaning solvent valve is closed and the air valve is opened, continuing for the second set time value. The advantage of this design is that by using high-pressure air to thoroughly purge the residual cleaning solvent and waste liquid in the pipeline to the waste liquid storage tank, it avoids solvent residue affecting subsequent paint spraying. At the same time, the solvent valve and air valve operate alternately in each cycle, enhancing the cleaning effect on the paint residue on the inner wall of the pipeline.

[0089] For example, after opening the cleaning solvent valve AlSolveBellC on the third pipeline for 2 seconds and then closing it, the cleaning air valve AlSolveBellCIU is opened and started for 1.8 seconds, and this process is repeated in a cycle.

[0090] Simultaneously, the cleaning solvent valve AlSolvCCU (lasting 0.35s) and the cleaning air valve AlSolvCCU (lasting 0.4s) on the first pipeline between the delivery pump and the launch station, and the second pipeline between the target station and the painting robot, are alternately opened to clean the pipeline between the delivery pump and the launch station. When the cleaning time accumulates to 8.6s, all cleaning solvent valves are closed, and all cleaning air valves AlSolvCCU are continuously opened for 2.5s to blow air through the pipeline, thus completing the cleaning procedure.

[0091] In one specific embodiment, step S4 specifically includes:

[0092] After cleaning the rapid color change system, samples of the mixed waste liquid solvent were collected from the first, second, and third pipes respectively.

[0093] Each pipe sample was placed in a spectrophotometer and its absorbance was measured in the entire visible light wavelength range to obtain the maximum absorbance value of each pipe sample in the entire wavelength range.

[0094] If at least one of the three pipes has a maximum absorbance greater than the photometric threshold, then all pipes with absorbance greater than the photometric threshold are obtained, and the cleaning parameters of the corresponding pipes are adjusted. After each parameter adjustment, the cleaning, sampling, and testing steps are repeated until the maximum absorbance of all pipes is less than or equal to the photometric threshold, at which point the cleaning parameter configuration is deemed qualified.

[0095] The configured cleaning parameters are stored in the storage unit for direct retrieval in subsequent spraying processes.

[0096] Specifically, this application collects waste liquid samples from different pipelines and uses full-band absorbance detection, taking the maximum absorbance value as the criterion for judging the cleaning effect. This achieves accurate and independent evaluation of the cleanliness of each pipeline, avoiding the ambiguity and inaccuracy of the overall judgment. For pipelines with excessive absorbance, directional parameter adjustments are performed, and the effectiveness of parameter optimization is ensured through iterative verification of repeated cleaning, sampling, and testing until all pipelines meet the qualification standard. Finally, the optimized qualified parameters are stored in the storage unit, providing directly retrieved optimized parameters for subsequent color paint switching, eliminating the need for repeated debugging processes and improving the efficiency of subsequent color change cleaning.

[0097] It is understandable that after cleaning, the mixed solvent samples are taken for spectrophotometer analysis: After cleaning the rapid color change system according to the initially set cleaning procedure, solvent samples are collected from the solvent sampling ports of the transmitter and target stations after cleaning, and placed in the spectrophotometer for absorbance analysis within the visible spectrum wavelength range (wavelength range 380nm-780nm, see...). Figure 3 The absorbance curve is compared with the absorbance of the blank solvent. If the absorbance value is within the range of 0-0.1 in any band, it is considered that there is basically no residual pigment in the solvent and it has been cleaned. If the absorbance value is above 0.1, it is considered that there is paint residue in the solvent and it has not been cleaned.

[0098] illustrative

[0099] The absorbance values ​​corresponding to the highest wavelengths within the visible spectrum analyzed by the spectrophotometer are input to the corresponding absorbance location on the human-machine interface. Based on the preset cleaning program's automatic optimization logic, the cleaning program automatically changes and iterates. Taking purple paint as an example, after executing the preset cleaning program, the absorbance is highest at wavelengths around 500nm and 650nm, with values ​​around 0.7-1. According to the preset optimization rules of the cleaning program, the solvent valve AlSolvCCU (duration 0.35s) and the air valve AlSolvCCU (duration [not specified]) are cleaned between the instrument and the launch station. The absorbance values ​​were increased by 0.7s (after inputting the absorbance values, the PLC program automatically adjusted the single cycle time of the cleaning solvent and air according to the preset values). The second cleaning was performed according to the optimized delivery pump and the cleaning solvent valve AlSolvCCU (duration 1.15s) and the cleaning air valve AlSolvCCU (duration 1.1s) between the transmitter and the station. After cleaning, the absorbance of each band was below 0.1, achieving the cleaning effect. The program was the optimal cleaning program and would not be iterated or updated. Finally, the optimal cleaning program and cleaning effect for each color were achieved.

[0100] The mapping relationship between the cleaning parameters corresponding to the absorbance value range is shown in the table below:
