Technical Field

[0001] The utility model relates to the field of industrial robots, and in particular to a compressed air circuit connection frame of a spraying robot. Background Art

[0002] In the automotive manufacturing industry, the paint spraying robots in the paint shop usually use two compressed air supply schemes. One scheme is that the compressed air from the large factory's air compressor station is pressurized by the supercharger in the workshop, and then directly supplied to the robot end through the robot station main line and branch lines. The other scheme is that the compressed air from the large factory is first connected to the branch lines of each robot through the robot main line, and then each robot is pressurized by a pneumatic booster cylinder and then supplied to the robot end.

[0003] However, in actual use, it was found that the second air supply solution had some problems. Due to the large average and instantaneous flow of compressed air on the robot side, the booster cylinders of each robot were frequently damaged. Therefore, it was necessary to optimize and improve the compressed air circuit of the on-site painting robot to reduce the frequency of use of the booster cylinders and thus extend their service life.

[0057] The structural principle and working principle of the utility model are described in detail below in conjunction with the accompanying drawings:

[0058] Figure 1 Schematic diagram of the compressed air connection structure of the spray robot in the prior art. Figure 1As shown, the compressed air pressure in the first main pipeline 1 is about 7 bar, and multiple first branch pipelines 2 are drawn from the first main pipeline 1 to provide to the spray robot 11 and the atomizer cleaning device 12 respectively. After the compressed air in the first branch pipeline 2 is pressurized by the booster cylinder 10, the air pressure is about 9 bar. A branch pipeline valve 13 is provided in front of the booster cylinder 10. In the spray robot 11 part, the first branch pipeline 2 also includes multiple first branch pipelines 5 ( Figure 1 The first branch air path 5 is used to transmit: the first spray molding air and motor brake air (air pressure ≥ 7 bar), the second spray molding air and motor brake air (air pressure ≥ 7 bar), the motor control air and valve switch control air (air pressure ≥ 7 bar), the robot pipeline purge air (air pressure ≥ 7 bar), the robot motor cooling air (air pressure ≥ 3 bar) and the motor suspension air (air pressure ≥ 6 bar). In the atomizer cleaning device 12, the first branch pipeline 2 includes multiple first branch air paths 5 ( Figure 1 A first branch gas path 5 is used to transmit: a first atomizer cleaning device purge gas (gas pressure ≥ 4 bar), a second atomizer cleaning device purge gas (gas pressure ≥ 6 bar), and an atomizer cleaning device valve control gas (gas pressure ≥ 5.5 bar).

[0059] The compressed air consumption data of the painting robot under different working conditions was obtained through measurement. During the robot's spraying process, the average consumption flow of the robot valve switch control air, the robot pipeline purge air, and the automatic pressure regulating valve control air is relatively small and can be ignored.

[0060] For the spray robot 11 using dual molding air, the flow rate of its spray molding air is determined according to the on-site process parameters, and the average consumption flow rate is about 700 L / min. The average consumption flow rate of motor suspension air is about 110 L / min, the average consumption flow rate of motor drive air (i.e. motor control air) and brake air is about 50 L / min, and the average consumption flow rate of robot motor cooling air is about 100 L / min. In this state, the atomizer cleaning device does not consume compressed air, and the average total consumption flow rate of compressed air for a single robot is about 1000 L / min.

[0061] When the robot runs the atomizer cleaning program, the average consumption of dual-molding air is 400 L / min, the average consumption flow of motor suspension air is about 110 L / min, and the average consumption flow of motor drive air and brake air is about 40 L / min. At this time, the average consumption flow of the atomizer cleaning device ring purge (i.e., the first atomizer cleaning device purge air and the second atomizer cleaning device purge air) is 700 L / min, and the average consumption flow of the atomizer cleaning device valve (i.e., the atomizer cleaning device valve control air) when it is alternately opened and closed is 200 L / min. In this state, the average total consumption flow of compressed air for a single robot is about 1550 L / min.

[0062] The model of the booster cylinder 10 used by a painting robot in a certain painting workshop is SMC brand VBA40A-F04. According to its product flow characteristic diagram, for a working environment of 7 bar before boosting and 9 bar after boosting, the maximum average flow rate that the booster cylinder 10 can provide is 1650 L / min. Before the transformation, the average consumption flow rate during atomizer cleaning was close to the equipment limit. Under single-shift production conditions, the average number of atomizer cleanings per day exceeds 20 times, which puts a huge load on the booster cylinder 10, and the average service life of each unit is only about 200 days.

[0063] Figure 2 This is a schematic diagram of the compressed air connection structure of the spray robot in one embodiment of the utility model. Figure 2 As shown, in order to solve the problem that the booster cylinder 10 is easily damaged due to frequent use, the embodiment of the utility model provides a compressed air circuit connection frame 20 of a spraying robot, comprising:

[0064] A plurality of spraying robots 11;

[0065] A first branch pipeline 2 corresponding to each of the plurality of spraying robots 11;

[0066] A plurality of atomizer cleaning devices 12, used for cleaning the atomizer of the spraying robot 11;

[0067] A second branch pipe 4 corresponding to each of the plurality of atomizer cleaning devices 12;

[0071] The boost cylinder 10 is disposed in the first branch pipeline 2 between the corresponding spray robot 11 and the first main pipeline 1, and the boost cylinder 10 is used to boost the compressed air in the first main pipeline 1 and provide it to the corresponding spray robot 11;

[0072] The second main line 3 is led out from the first main line 1 , and the second main line 3 provides compressed air to the plurality of atomizer cleaning devices 12 and / or the spraying robot 11 through the plurality of second branch lines 4 connected thereto.

[0073] In one embodiment, the atomizer cleaning device 12 corresponds one to one with the spraying robot 11. The atomizer cleaning device 12 may also correspond to a plurality of spraying robots 11, but the present invention is not limited thereto.

[0074] Figure 3 FIG. 1 is a schematic diagram of the compressed air connection between the spray robot and the atomizer cleaning device in one embodiment of the utility model. Figure 3 As shown, in one embodiment, the first branch pipeline 2 further includes a plurality of first branch air paths 5, which are at least used to provide the first spray molding air and motor brake air, the second spray molding air and motor brake air, the motor control air and the valve switch control air, and the robot pipeline purge air. In this embodiment, the first branch pipeline 2 is composed of a pre-pressurization part 2a and a post-pressurization part 2b, and the post-pressurization part 2b includes a plurality of first branch air paths 5a, 5b, 5c, 5d and 5e. It should be noted that the number of the first branch air paths can be increased or decreased as needed, and the utility model is not limited thereto.

[0075] like Figure 3 As shown, in one embodiment, the second branch pipeline 4 further includes a plurality of second branch air circuits 6, which are at least used to provide the first atomizer cleaning device purge gas, the second atomizer cleaning device purge gas, the atomizer cleaning device valve control gas and the robot motor cooling gas. In this embodiment, the second branch pipeline 4 is connected to the second main pipeline 3, and the second branch pipeline 4 includes a plurality of second branch air circuits 6a, 6b, 6c and 6d. It should be noted that the number of second branch air circuits can be increased or decreased as needed, and the plurality of second branch air circuits can all supply air to the atomizer cleaning device 12 as needed, and can also supply air to the spray robot 11 and the atomizer cleaning device 12 at the same time, and the utility model is not limited to this.

[0076] In one embodiment, a first valve 13 a is disposed on one end of the second main line 3 connected to the first main line 1 .

[0077] In one embodiment, a filter 14 is disposed on the second main pipeline 3 between the first valve 13 a and the second branch pipeline 4 .

[0078] In one embodiment, a second valve 13 b is disposed on the second main line 3 at the front end of the filter 14 .

[0079] The benefit of providing the first valve 13a and the second valve 13b is that it is convenient for the inspection and maintenance of the equipment and the replacement of the filter element, thereby improving the maintenance efficiency of the equipment.

[0080] It should be noted that the filter 14 and the valve before the filter 14 may also be arranged in the first branch pipeline 2, but the present invention is not limited thereto.

[0081] Figure 4 Schematic diagram of the compressed air connection structure of the spraying robot in another embodiment of the utility model. Figure 4 As shown, the main difference between the compressed air circuit connection frame 30 of the spraying robot in one embodiment and the compressed air circuit connection frame 20 of the spraying robot is that a compressed air distribution module 15 is provided at the rear end of the filter 14, which is used to effectively distribute the compressed air in the second main pipeline 3 to a plurality of the second branch pipelines 4. The compressed air distribution module 15 can distribute the compressed air into compressed air of a plurality of branches as required, and the compressed air of each branch can have the same or different air pressures. The structure of the compressed air distribution module is prior art and will not be described in detail here.

[0082] In one embodiment, a pressure sensor and / or a flow sensor is disposed on the second main pipeline 3 between the first valve 13 a and the second branch pipeline 4 .

[0083] After the pipeline optimization and transformation of the compressed air connection frame of the spray robot of the utility model, the compressed air consumption of the spray painting robot under different working conditions has been significantly reduced. When the robot is spraying, the compressed air reduces the output flow of the booster cylinder 10 by 100 L per minute, and the average total flow of compressed air consumed after optimization is 900 L / min. When the robot runs the atomizer cleaning program, the compressed air reduces the output flow of the booster cylinder 10 by 1000 L per minute, and the average total flow of compressed air consumed after optimization is 550 L / min. After the transformation, the service life of the booster cylinder 10 can be doubled. The results of these optimizations and improvements show that the scheme can effectively improve the work efficiency of the spray painting robot, reduce operating costs, and significantly extend the service life of the equipment.

[0084] Figure 5 FIG. 1 is a schematic block diagram of a spraying workshop 100 in one embodiment of the present invention. Figure 5As shown, the utility model also discloses a spraying workshop 100, including a compressed air source 120, a plurality of spraying units 110 and a control center 130 connected to the plurality of the spraying units 110, the control center 130 is used to control the spraying and cleaning of the plurality of the spraying units 110, the spraying units 110 include a spraying robot 11 and an atomizer cleaning device 12, the compressed air source 120 and the plurality of the spraying units 110 are connected using any one of the above-mentioned compressed air circuit connection frames of the spraying robot 11.

[0085] In the compressed air connection architecture of the spray robot 11 of the utility model, the second main line 3 is derived from the first main line 1, and the second main line 3 provides compressed air to multiple atomizer cleaning devices 12 and the spray robot 11 through multiple second branch lines 4 connected thereto, which effectively extends the service life of the booster cylinder and reduces the frequency of equipment replacement under the condition of minimum modification cost; reduces the downtime and frequency caused by damage to the booster cylinder 10, thereby improving production efficiency; and also reduces the air pressure of the air supply of the air compressor station, saving the operating cost of the station building.
