[0035] Example

[0036] Reference Figure 1 and Figure 2 This utility model provides a robotic line spraying system, which includes multiple spraying devices arranged in sequence;

[0037] The spraying device includes two spraying components; the two spraying components are arranged on the same side; after the plastic part passes through one of the spraying components, the plastic part rotates 180° and then passes through the other spraying component.

[0038] In some embodiments, the robotic line spraying system includes multiple spraying devices, each of which includes two spraying components. Each spraying component includes a robot, which is used to spray the plastic parts.

[0039] Two spraying components are located on the same side. After the plastic part passes the first spraying component, it rotates between the two spraying components. Generally, the plastic part is hoisted, and a rotary motor is installed on the hoisting mechanism. When the plastic part moves between the two spraying components, it rotates 180°, so that the unsprayed side of the plastic part faces the other spraying component. The other spraying component then sprays the plastic part, thus completing the spraying of the entire plastic part.

[0040] Multiple spraying devices are set up in sequence, which can complete the corresponding spraying in sequence; compared with manual spraying, it reduces manual operation, shortens the coating cycle, and improves spraying efficiency.

[0041] In an optional embodiment, the plurality of spraying devices are sequentially a conductive water spraying device, a primer spraying device, a topcoat spraying device, and a gold oil spraying device.

[0042] The multiple spraying devices are a conductive water spraying device, a primer spraying device, a topcoat spraying device, and a gold oil spraying device; the plastic parts pass through the conductive water spraying device, primer spraying device, topcoat spraying device, and gold oil spraying device in sequence.

[0043] After the plastic parts pass through the conductive water spraying device, they pass through the primer spraying device. After passing through the primer spraying device, the plastic parts need to be leveled for a period of time. After passing through the topcoat spraying device, the plastic parts need to be leveled for a period of time again. Then they are moved to the gold oil spraying device.

[0044] Reference Figure 1 In an optional embodiment, the conductive water spraying device includes a first material tank 100 and a first weighing device 200, wherein the first material tank 100 is disposed on the first weighing device 200.

[0045] A first spraying pipeline 300 is provided inside the first material tank 100, and a first diaphragm pump 400 is provided on the first spraying pipeline 300.

[0046] Two spraying branches 500 are provided on the first spraying pipeline 300. One end of each spraying branch 500 is connected to the first spraying pipeline 300, and the other end is connected to the air gun 600.

[0050] When the air gun 600 is in the constant state, the first switch valve 800 is in the open state, and the material in the first material tank 100 enters the first spraying pipeline 300 through the first diaphragm pump 400, and then enters the spraying branch 500.

[0051] The first gear pump 700 pressurizes the material again. The pressurized material enters the first switch valve 800 and then enters the air gun 600, or enters the first return pipeline 900 through the first switch valve 800 and then returns to the first material bucket 100.

[0052] That is, the first diaphragm pump 400 and the first gear pump 700 are always in working condition. When the air gun 600 is not in working condition, the first switching valve 800 is closed, and the first switching valve 800 allows the material in the spraying branch 500 to enter the first return pipe 900. In this way, the air gun 600 is temporarily shut off, and it is not necessary to shut down the first diaphragm pump 400 and the first gear pump 700.

The solvent is a commonly used solvent for cleaning paint, such as organic solvents containing methanol, acetone, xylene, etc.

[0062] For electrostatic ring cup 190, a Lands electrostatic rotary cup is generally selected; when the coating distance is 50-150 mm, a high coating rate is achieved. Compared with the traditional rotary cup, the actual coating coating rate is increased by 30% to 35%, and no high voltage abnormality is generated. Therefore, the coating efficiency is greatly improved compared with the previous coating method.

[0063] It features double-helix air atomization capability for better penetration; the paint mist is free of voids, and the arrangement of metal particles when spraying metallic paint is close to that of a spray gun, resulting in good coverage uniformity and high transmission efficiency; suitable for oil-based paint spraying; the Ranswick RMB26 proximity automatic electrostatic rotary cup improves electrical safety through the current / voltage value control of the new controller and new cascading, resulting in significant cost reduction. High coating efficiency helps reduce paint usage, reduce repair work, and reduce the maintenance and management of coating equipment, and can widely cope with various coating conditions.
