Abstract
Description
Technical Field
[0001] In general, this utility model relates to motor vehicle production and processing equipment. More specifically, it relates to industrial painting robot pipeline cleaning equipment, and in particular to cleaning equipment for efficiently and thoroughly cleaning the secondary pipelines of industrial painting robots. Background Technology
[0002] Motor vehicle manufacturers need to paint the surfaces of vehicle body parts (such as engine hood, roof panel, door side panels, front / rear body panels, etc.) to meet requirements for weather resistance, corrosion resistance, and aesthetics.
[0003] Painting / spraying of vehicle exterior components typically takes place in the painting / spraying workshops of vehicle manufacturing companies. In the earliest history of vehicle production, this painting / spraying work was performed manually by operators (humans). With continuous technological advancements, painting robots are now widely used to replace human operators in painting operations. This avoids the adverse health effects of paint volatiles on operators and also makes painting operations more accurate, efficient, and economical.
[0004] Figure 1 The diagram shows a schematic of a prior art robotic painting system, which includes: multiple painting robots 1 for spraying paint onto the outer surface of vehicle body parts; a paint supply device 2 equipped with a paint reservoir for supplying paint to the painting robots 1; and a main paint pipeline 3 fluidly connected to the paint outlet of the paint supply device 2, allowing fresh, clean paint from the paint supply device 2 to be supplied into the main paint pipeline 3, for example, along a path such as... Figure 1 The bold arrow on the lower left side of the main paint pipe 3 indicates that fresh, clean paint is supplied from the paint supply device 2 to the main paint pipe 3; multiple secondary pipes 4 ( Figure 1 The diagram schematically shows six secondary pipelines 4 (this number is not limited). These secondary pipelines 4 are arranged sequentially and alternately on the main paint pipeline 3 along the paint flow direction of the main paint pipeline 3 and are in fluid communication with it. Each of the secondary pipelines 4 includes an inlet end and an outlet end. The inlet end is fluidly connected to the main paint pipeline 3, and the outlet end is fluidly connected to the spraying robot 1. Fresh, clean paint from the main paint pipeline 3 can flow into the inlet end, through the internal channels of the secondary pipeline 4, and then out of the secondary pipeline 4 from the outlet end and into the spraying robot 1. The flow direction of the fresh, clean paint in the secondary pipelines 4 is, for example, as shown in... Figure 1The vertically arranged arrows indicate the areas indicated by reference numeral 4 in the attached diagram. The paint flowing into each painting robot 1 can be sprayed out from the paint outlet end 5 of the painting robot 1 under the predetermined control of the painting robot 1 (see Figure 4). Figure 1 The two schematic reference numerals at the top (5) are for the purpose of applying appropriate painting operations to the outer surfaces of various motor vehicle body parts.
[0005] In some applications, the downstream end of the paint main pipeline 3 is fluidly connected to the paint supply device 2 (e.g., along such a pipeline). Figure 1 (as shown by the direction of the bold arrow on the lower right side of the paint main pipeline 3), thus forming a closed loop with the paint supply device 2, as shown in the example. Figure 1 As shown.
[0006] Regarding the cleaning of the secondary pipeline of the spraying robot
[0007] The painting robot 1 has two modes: working mode and standby mode (standby mode is also known as non-working mode). During the vehicle production process, when a batch of vehicle body parts needs to be painted, the operator puts the painting robot 1 into working mode, that is, turns it on to enter the painting operation mode, and performs the set painting operation on the surface of this batch of vehicle body parts. When the painting operation of this batch of vehicle body parts is completed, the operator puts the painting robot 1 into standby (non-working) mode, that is, turns it off to stop the painting operation. When the next batch of vehicle body parts needs to be painted, the operator will put the painting robot 1 back into working mode, that is, turn it on to re-enter the painting operation mode, and paint the surface of the next batch of vehicle body parts. In this way, the painting robot 1 cycles between working mode and standby (non-working) mode multiple times.
[0008] During prolonged standby mode, the paint in the secondary pipeline 4 of the painting robot remains completely still and does not circulate. This still paint in the secondary pipeline 4 during standby will precipitate and crystallize over time, producing solid particles. These solid particles, in subsequent operating modes, will enter the painting robot's pipeline from the secondary pipeline 4 along with the liquid paint supplied from the main paint pipeline 3. They will then be transported to the surface of the vehicle body parts being painted during the painting operation, affecting the paint quality of the painted vehicle body parts.
[0009] Existing technology for secondary pipeline cleaning in spray painting robots
[0010] In existing technologies, to maintain the cleanliness of the secondary pipeline inside the painting robot (free from particulate impurities caused by paint crystallization and precipitation), after a certain number of painting batches, a method is adopted... Paint flushing and displacement cleaning To flush the secondary pipeline of the painting robot. For example... Figure 1 As shown in Figure 5, the prior art's " Paint flushing and displacement cleaning "After a certain number of batches of painting operations, the working mode is activated, but the paint sprayed from the paint outlet 5 of each painting robot 1 (which may contain particulate impurities) is not sprayed onto the vehicle body parts, but instead discharged into a separately set waste paint storage tank. After a certain period of time, the inner cavity of the secondary pipeline 4 of the painting robot is flushed and replaced by fresh and clean paint from the main paint pipeline 3, so that the inner cavity of the secondary pipeline 4 of the painting robot basically reaches the cleanliness level that can be achieved."
[0011] As can be seen from the above, the existing technology adopts " Paint flushing and displacement cleaning This method results in a significant waste of fresh, clean paint, and the cleaning effect is unsatisfactory because this method... Paint flushing and displacement cleaning "This method cannot completely remove particles from the secondary pipeline 4, thus failing to satisfactorily guarantee the paint quality of the subsequently painted vehicle parts." Utility Model Content
[0012] As mentioned above, because the paint in the secondary pipeline of the painting robot remains completely still and does not circulate in each standby mode, after multiple painting / standby cycles over a long period, the paint in the secondary pipeline of the painting robot will precipitate, crystallize, or form particles. This will lead to a deterioration in the paint quality of the painted vehicle body parts. Using the currently conventional method described above... Paint flushing and displacement cleaning "Cleaning the secondary pipeline in this way cannot completely remove particles from the secondary pipeline of the painting robot, and it will also result in a lot of paint loss. In order to ensure the quality of the paint surface of the vehicle body parts, the robot's secondary pipeline must be cleaned regularly and thoroughly."

[0084] Example of usage / operation steps for the 100-stage secondary pipeline cleaning equipment for industrial spraying robots
[0085] In practice, when it is necessary to clean a batch or a specific secondary pipeline 4, the operator can use at least some of the following operating procedures:
[0086] -like Figure 3 and Figure 4 As shown, the inlet end of the secondary pipeline 4 is connected to the inlet valve (e.g., is...) Figure 3 The ball valve shown is disengaged so that the inlet end of the secondary line 4 is disconnected from the main paint line 3, and the inlet end of the secondary line 4 is sealed and installed to the end of the outlet line 122 of the pump 120 away from the pump 120 (see...). Figure 2 )superior;
[0087] -like Figure 3 and Figure 4As shown, the outlet end of the secondary pipeline 4 is removed from the base of the spraying robot 4. Specifically, the connection between the outlet end of the secondary pipeline 4 and the outlet valve 410 (which can be a Y-type valve) at the fresh paint inlet of the spraying robot 1 can be separated, and then the outlet end of the separated secondary pipeline 4 can be connected to the paint solvent reservoir 130. For example, in an embodiment where the paint solvent reservoir 130 is equipped with a filter device 131 (the filter device 131 has a filter bag 1311 inside), the outlet end of the separated secondary pipeline 4 is connected to the filter device 131, and the outlet end of the separated secondary pipeline 4 is sealed and fixed on the filter device 131 using a pipeline fixing device.
[0088] - Add paint solvent to the paint solvent reservoir 130. Note that in some embodiments of this utility model, since most of the volume of the filter device 131 is located inside the paint solvent reservoir 130, the total volume of paint solvent added to the paint solvent reservoir 130 should not exceed 2 / 3 of the volume of the paint solvent reservoir 130.
[0089] - Connect the pressurized air inlet pipe 123 of pump 120 (see...) Figure 2 (As shown) Connect to a pressurized air source;
[0090] - Lock the locking / unlocking mechanism of the caster wheel 150, and slowly open the air supply switch 1231 of the pump 120. In some embodiments, when opening the air supply switch 1231 of the pump 120, the air supply switch 1231 is opened to at most 1 / 2 of its maximum opening degree; and
[0091] -Start pump 120 to begin circulating the paint solvent in order to clean the secondary pipeline 4.
[0092] like Figure 4 left side and combination Figure 2 As shown, in some embodiments of this utility model, the circulation path of the paint solvent is as follows: paint solvent reservoir 130, inlet pipe 121 of pump 120, internal pipeline of pump 120, outlet pipe 122 of pump 120, secondary pipeline 4 to be cleaned, and filter device 131.
[0093] This invention offers numerous beneficial technical advantages:
[0094] This invention utilizes the secondary pipeline of a paint solvent cleaning spraying robot, which can efficiently and thoroughly remove solid particles from the secondary pipeline to ensure the paint quality of motor vehicle body parts and avoid paint waste.
[0095] In some embodiments of this invention, the secondary pipeline of the spraying robot is cleaned by solvent circulation, which can save solvent.
[0096] In some embodiments of this invention, the filter device 131 prevents contamination of the solvent in the paint solvent reservoir 130, thus preventing contamination of the next pipeline to be cleaned. Furthermore, it allows the paint solvent in the paint solvent reservoir 130 to be reused multiple times. For each cleaning operation (one cleaning operation can clean multiple secondary pipelines 4), only a new filter bag 1311 needs to be replaced before the cleaning operation. This allows for more effective conservation of paint solvent.
[0097] Although the present invention has been described in detail based on embodiments or aspects currently considered to be the most practical and preferred, it should be understood that the various details disclosed in this specification are illustrative and not limiting. The present invention is not limited to the disclosed embodiments, but should be covered by various modifications and equivalent designs within the inventive spirit of the present invention.
