Description

Technical Field

[0001] The invention relates to the field of robot spraying processing, and in particular to an integrated spraying system. Background Art

[0002] In the process of casting parts, the demoulding of castings requires spraying of demoulding agents. The demoulding agents can adjust the temperature inside the mold, improve the demoulding performance of the castings and the working conditions of the mold, prevent mold sticking, and reduce the thermal conductivity and temperature of the mold.

[0003] With the continuous improvement of the degree of automation in parts processing, special spraying equipment is currently used to approach the mold through robot grabbing to spray the release agent. However, the existing spraying equipment faces some problems: 1. The spraying equipment currently in use integrates dozens of nozzles to improve the spraying effect; and when the mold is larger, the spraying area increases, and the number of nozzles required will also increase accordingly, resulting in a further increase in the volume and weight of the equipment. 2. In order to achieve the purpose of uniform spraying, atomizing nozzles are usually used, and each atomizing nozzle requires two pipelines to connect the paint and compressed air; and the power supply during spraying is also taken from the robot or related production line, resulting in more external pipes for existing spraying equipment. 3. In order to ensure the mobility of the robot, the pipeline needs to reserve a large margin, which makes it easy for the pipeline to rub against the equipment, the ground and the robot, causing the pipeline to wear or even break. Therefore, the existing spraying equipment has many pipelines, large volume, and heavy weight, resulting in a large load on the robot and the risk of pipeline wear.

[0004] In order to solve the above problems, the applicant has developed a spraying equipment and a spraying device (publication number: CN207507681U; application date: 2017-11-03), which introduces external paint, atomizing gas and drying gas into the spraying equipment from the paint main interface and the atomizing gas main interface respectively, distributes the fluid to each nozzle through the channel integrated component, and sprays it out from the nozzle on the nozzle mounting plate. This can significantly reduce the number of pipelines, reduce the load of the robot, avoid the wear problem of the pipeline, and improve the reliability and work efficiency of the equipment. The applicant found that the spraying device has the following areas that need to be further optimized when used on large molds:

[0005] 1. When spraying large molds, the spraying equipment integrates a larger number of nozzles and a drying air pipeline for drying the spraying area after spraying. The applicant found that when only the internal branch channel is used to transport the drying air to a large number of drying air pipelines, a large number of internal branch channels with large inner diameters are required, which will further increase the volume and weight of the spraying equipment, further increase the load of the robot, and seriously affect the service life of the robot. In addition, only transporting the drying air through the internal flow channel will also have the problems of low drying air delivery efficiency and small drying air flow, which cannot meet the needs of large-scale mold drying, and also seriously restricts the drying efficiency, thereby affecting the efficiency of the entire spraying process.

[0006] 2. When the atomizing nozzle needs to be removed for maintenance due to impurities or other reasons, in the current spraying device, the release agent is controlled by the nozzle itself. When the nozzle is removed for maintenance, the release agent may leak, resulting in inconvenient nozzle maintenance and waste of release agent. Summary of the invention

[0019] The principles and beneficial effects of this scheme are:

[0020] 1. This solution controls the on and off of the release agent by setting a release agent valve in the valve control plate. When spraying the release agent, the release agent with pressure is introduced from the release agent inlet. The release agent valve opens under the action of the release agent, so that the release agent can flow from the release agent outlet to the first diverter plate, and then flow into the nozzle after being diverted by the first diverter plate and the second diverter plate. This solution uses the release agent valve to control the on and off of the release agent at the front end. Compared with relying solely on the nozzle itself to control the on and off of the release agent, it is more convenient to control it through the release agent valve. When the nozzle is removed for maintenance, the release agent supply can be cut off through the release agent valve, thereby avoiding leakage of the release agent during maintenance, which is convenient for nozzle maintenance and will not cause release agent leakage. In addition, cutting off the release agent supply through the release agent valve when not spraying can also avoid the nozzle from being pressurized all the time, thereby effectively protecting the nozzle and extending the service life of the nozzle.

[0021] 2. This solution integrates multiple blow-drying air valves in the valve control board, and introduces compressed air through the air inlet channel to drive all the blow-drying air valves to open at the same time, ensuring the flow and pressure of the blow-drying air, which is more efficient than opening multiple blow-drying air valves in sequence.

[0022] 3. Multiple drying air valves divide the drying air into two paths and enter the external drying air channel, and then connect to the drying air main pipe. On this basis, this solution connects the external drying air channels on both sides through a circular drying air connection channel, which can unify the flow of the external drying air channels on both sides and ensure that the drying air on both sides can be fully utilized. On this basis, this solution sets a spare drying air interface on the drying air connection channel to facilitate the external connection of a spare drying air main pipe when needed.

[0023] 4. This solution uses the external drying air main pipe and the internal drying air channel to ventilate the drying air branch pipe in different areas at the same time, which can not only ensure the large flow rate of drying air required by large molds, but also allow the drying air to be introduced more quickly, with a fast response speed, thereby improving the efficiency of drying. If only the internal drying air channel is ventilated, in order to achieve the same flow rate and speed, the number or diameter of the internal drying air channels needs to be increased, which will not only increase the difficulty of equipment processing and the difficulty of internal drying air channel processing, but also increase the volume and weight of the nozzle integrated structure, thereby increasing the load and movement difficulty of the robot, and affecting the service life of the robot.

[0024] 5. The release agent valve and the blow-drying valve are integrated in the valve control plate. The introduction of compressed air, the diversion of the release agent and the diversion channel of the internal blow-drying air are all integrated on the first diversion plate. Compared with integrating the valve group and the diversion channel on one plate, the split structure facilitates the processing and installation of the valve group and the flow channel, reducing the processing difficulty.

[0025] 6. This solution divides the pipeline into a first pipeline, a second pipeline, a third pipeline and a fourth pipeline, wherein the second pipeline, the third pipeline and the fourth pipeline are arranged along the outside of the robot, which effectively reduces the margin of the pipeline and prevents the pipeline from being dragged on the ground, thereby avoiding friction between the pipeline and the ground and greatly reducing friction between the pipeline and the robot and other equipment.

[0026] On this basis, the present solution connects the first pipeline and the second pipeline through a first rotating joint, and the connection between the third pipeline and the fourth pipeline is connected to the robot as a whole through a rotating mounting seat. The advantages of this design are: (1) Since the connection between the first pipeline and the second pipeline is rotationally connected, when the robot as a whole rotates on the rotating base, the first pipeline and the connection between the first pipeline and the second pipeline can be effectively prevented from twisting, thereby effectively protecting the first pipeline and the connection, and the robot movement will not be affected by the pulling and twisting of the first pipeline. (2) Since the connection between the third pipeline and the second pipeline is rotationally connected to the robot arm as a whole through the rotating mounting seat, when the robot's forearm swings up and down, the rotating mounting seat can be driven to rotate with it through the third pipeline, thereby avoiding the problem of the third pipeline being pulled and causing damage to the third pipeline and restricting the robot's movement, and also avoiding the twisting and damage of the connection between the third pipeline and the second pipeline. (3) If the pipeline is only set along the outside of the robot, in order not to affect the movement of the robot, the pipeline still needs to have a certain margin. The design of the present application can further reduce the margin of the pipeline on the basis of fixing the pipeline on the robot, thereby further avoiding pipeline wear.

[0027] In summary, this solution fixes the pipeline along the outside of the robot and movably sets the pipeline at the key rotation nodes of the robot, which not only reduces the margin of the pipeline and avoids pipeline wear, but also does not limit the mobility of the robot.

[0050] Combination Figure 7 , Fig.12 and Fig.13As shown, multiple blow-drying valves 816 are also installed in the valve control plate 81, and the structure and principle of the blow-drying valves 816 are the same as those of the release agent valves 814. The multiple blow-drying valves 816 are arranged in two rows, and an air inlet channel 822 is also opened on the first diverter plate 82 along the length direction. The air inlets of the multiple blow-drying valves 816 are all connected to the air inlet channel 822, and external blow-drying air channels 817 are opened on both sides of the blow-drying valves 816. The two adjacent air outlets of the two rows of blow-drying valves 816 are connected, and the two air outlets far away from each other are respectively connected to the external blow-drying air channels 817 on both sides. The two external blow-drying air channels 817 are both connected to the blow-drying air main pipe 88 installed outside the first diverter plate 82, and the two blow-drying air main pipes 88 are both connected to a number of blow-drying air branch pipes integrated on the nozzle assembly. An annular drying air connection channel 818 is provided below the external drying air channel 817, and the drying air connection channel 818 connects the external drying air channels 817 on both sides, and the drying air connection channel 818 is also connected to a spare drying air interface 810. An internal drying air channel 823 is also provided in the first diverter plate 82, and the drying air connection channel 818 on one side of the valve control plate 81 is connected to the internal drying air channel 823, and the second diverter plate 83 and the bottom plate 85 are provided with internal drying air flow paths 833 that are connected to each other, and the internal drying air channel 823 is connected to the internal drying air flow path 833, and the internal drying air flow path 833 is also connected to the drying air branch pipe.

[0051] Combination Fig.14 As shown, a plurality of atomizing gas channels 820 are laterally connected on both sides of the air inlet channel 822, and an atomizing valve plate 84 is bolted on the front and rear sides of the first diverter plate 82. A plurality of atomizing valves 840 are installed in the atomizing valve plate 84. The structure and principle of the atomizing valve 840 are the same as those of the release agent valve 814. The atomizing gas channel 820 is connected to the air inlet of the atomizing valve 840, and the air outlet of the atomizing valve 840 is connected to the atomizing gas inlet of the nozzle through the atomizing gas diverter channel 830 opened in the second diverter plate 83 and the bottom plate 85.

[0052] The first pipeline, the second pipeline 2, the third pipeline 3 and the fourth pipeline 4 each include a compressed air pipeline 22 and a release agent pipeline 21. The two pipelines of the first pipeline and the second pipeline 2 are connected by rotation through the two first rotary joints 55 on the first mounting plate 50. The other ends of the two pipelines of the second pipeline 2 are fixed on the second mounting plate 64 and are correspondingly connected with the two pipelines of the third pipeline 3. The other ends of the two pipelines of the third pipeline 3 are connected with the fixed joints 71 on the mounting seat 70. The top end of the fourth pipeline 4 is connected with the rotary joint on the mounting seat 70. The release agent pipeline 21 in the fourth pipeline 4 is connected with the two release agent inlets 811 on the valve control plate 81 through the release agent inlet channel 861 on the mounting block 86. The compressed air pipeline 22 in the fourth pipeline 4 is connected with the air inlet channel 822 on the first diverter plate 82 through the compressed air inlet channel 862 on the mounting block 86.

[0053] The integrated spraying system is used as follows:

[0054] The compressed gas and the release agent are respectively transported to the flow control mechanism 8 through the compressed gas pipeline 22 and the release agent pipeline 21 for flow diversion, which greatly reduces the number of pipelines. In addition, the pipelines are divided into a first pipeline, a second pipeline 2, a third pipeline 3 and a fourth pipeline 4, wherein the second pipeline 2, the third pipeline 3 and the fourth pipeline 4 are arranged along the outer side of the robot, which effectively reduces the excess of the pipeline, so that the pipeline will not be dragged on the ground, avoiding the friction between the pipeline and the ground, and reducing the friction between the pipeline and the robot and other equipment.

[0055] When the robot as a whole rotates based on the rotating base 11, since the first pipeline and the second pipeline 2 are connected by the first rotating joint 55, the first pipeline and the connection between the first pipeline and the second pipeline 2 can be effectively prevented from twisting, thereby effectively protecting the first pipeline and the connection, and the robot movement will not be affected by the pulling and twisting of the first pipeline. In addition, since the connection between the third pipeline 3 and the second pipeline 2 is integrally connected to the robot arm 12 through the rotating mounting seat 70, when the robot's small arm 13 swings up and down, the rotating mounting seat 70 can be driven to rotate with it through the third pipeline 3, thereby avoiding the problem of the third pipeline 3 being pulled and causing damage to the third pipeline 3 and limiting the robot's movement, and also avoiding the twisting and damage of the connection between the third pipeline 3 and the second pipeline 2.

[0056] The release agent is transported to the valve control plate 81 through the release agent pipeline 21, and enters into two release agent valves 814 from the release agent inlet 811 on the valve control plate 81. The release agent valves 814 are opened under the action of the release agent, and the release agent flows out from the discharge ports 813 on both sides of the release agent valves 814. After flowing out, the release agents in the two release agent valves 814 are merged through the release agent connecting channel 860 in the mounting block 86, and then flow into the first release agent branch channel 821 in the first branch plate 82 for the first branch, and then flow into the second release agent branch channel 831 in the second branch plate 83 for the second branch into several release agent flows, and finally transported to the nozzle.

[0057] The compressed gas is transported to the first diverter plate 82 through the compressed gas pipeline 22. At this time, the blow-drying valve 816 is closed, and the compressed gas enters the multiple atomizing gas channels 820 on both sides from the air inlet channel 822 on the first diverter plate 82 at the same time, and then enters the atomizing valve 840. The atomizing valve 840 is opened, and the atomized gas is finally transported from the air outlet of the atomizing valve 840 to the nozzle to mix with the release agent in the nozzle. The release agent is atomized under the atomization action of the atomizing gas and sprayed onto the mold.

[0058] After spraying is completed, the atomizing valve 840 is closed, and the compressed air enters from the air inlet channel 822 and enters multiple blow-drying valves 816 at the same time. The blow-drying valves 816 are opened, and the blow-drying air enters two external blow-drying air channels 817. Finally, the blow-drying air is transported to the blow-drying air branch pipes from the outside and the inside through two blow-drying air main pipes 88 and multiple internal blow-drying air channels 823 to blow-dry the mold.

[0059] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
