Description

Technical Field

[0001] This utility model belongs to the field of aerospace composite material product spraying technology, specifically relating to an automatic spraying device for coatings with fiber fillers. Background Technology

[0002] Currently, there are coatings containing fiber fillers in aerospace composite material products. These coatings contain fibers as fillers, and the fiber content is relatively high. When this coating is sprayed using automated equipment, the fiber filler accumulates in the paint supply module and valve ports due to the long pipeline and the presence of paint control valves, causing pipeline blockage. This makes it impossible to use automated equipment for spraying. Therefore, in actual production, this coating can only be sprayed manually.

[0003] As composite materials are used more and more widely in aerospace, and the size of composite materials products is getting larger and larger, traditional manual spraying is gradually being replaced by automated spraying equipment due to high labor intensity and poor working environment. However, since this type of coating cannot be sprayed in automated equipment, the product coating cannot achieve fully automated manufacturing.

[0004] This invention enables automated spraying of fiber-filled coatings, achieving fully automated manufacturing of product coatings. Utility Model Content

[0005] This invention addresses the problems of manual spraying of fiber-filled coatings, which is labor-intensive, has a poor working environment, and is highly susceptible to human error in terms of spraying quality. It provides an automated spraying device for fiber-filled coatings, enabling fully automated spraying of these coatings and improving the automation level of the entire product manufacturing process. This device effectively avoids the disadvantages of manual spraying and improves the working environment for on-site operators.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic spraying device for coatings with fiber fillers, comprising:

[0008] Robots, which provide mobility;

[0009] A spray gun, which is mounted at the end of the robot;

[0010] A syringe-type feeding tank is installed at the end of the robot and connected to a spray gun;

[0011] Both the spray gun and the needle-type feed canister are connected to an air pump, and the spray gun has two air lines to control the on / off state of the spray gun and the spray pattern, respectively.

[0012] As a further embodiment of this utility model: the robot is mounted on a base, and a bracket is fixedly connected to its end. The spray gun and the syringe-type feeding tank are both mounted on the bracket.

[0013] As a further embodiment of this utility model: the spray gun is connected to an air pump through two compressed air pipelines, and a second air regulating valve is provided on one of the compressed air pipelines to adjust the spray pattern of the spray gun.

[0014] As a further embodiment of this utility model: the needle-type feed tank is connected to an air pump through a compressed air pipeline, and a first air regulating valve is provided on the compressed air pipeline to regulate the pressure inside the needle-type feed tank, thereby regulating the flow rate.

[0015] As a further embodiment of this utility model: the needle-type feeding tank includes a pressure tank and an injection piston, the injection piston is sealed and connected in the pressure tank, and the compressed air pipeline is connected to the pressure tank to push the injection piston to move in the pressure tank.

[0016] As a further aspect of this invention, the capacity of the pressure tank is related to the size of the parts being coated.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0018] 1. This application enables automated spraying of coatings with fiber fillers, avoiding the situation where automated equipment spraying and manual spraying are carried out simultaneously during the product spraying process. It can improve the automation level of the product coating manufacturing process, improve the product spraying quality, improve the working environment of on-site operators, and reduce the labor intensity of operators.

[0019] 2. In this application, the spray gun is directly connected to the material supply pressure tank, without any additional pipelines or control valves, thus avoiding the possibility of blockage by the fiber filler. Automatic on / off control of the spray gun is achieved via signals from the equipment. The pressure inside the material supply pressure tank is controlled by an air pressure regulating valve, which alters the paint flow rate, thereby controlling the paint flow. The spray gun spray pattern control switch is connected to compressed air; the spray pattern size during product spraying can be adjusted by regulating the air pressure regulating valve on the control cabinet.

[0030] Both the spray gun 3 and the needle-type feed tank 4 are connected to an air pump, and the spray gun 3 is equipped with two air lines, which control the on / off state of the spray gun 3 and the spray pattern, respectively.

[0031] Preferably, the robot 2 is mounted on the base 1, and its end is fixedly connected to the bracket 9. The spray gun 3 and the needle-type feeding tank 4 are both mounted on the bracket 9.

The compressed air pipeline 6 is connected to the pressure tank and pushes the injection piston 10 to move in the pressure tank 5.

[0035] Preferably, the capacity of the pressure tank 5 is related to the size of the parts being coated.

[0036] The paint supply module is installed at the end of robot 2, reducing pipeline length and avoiding paint waste caused by excessively long pipelines. The robot is installed in base 1. The paint supply module uses a needle-type paint supply tank 4 for paint supply. Pressure tank 5 is directly connected to spray gun 3, without any extra pipelines or control valves in between. Spray gun is connected to the end of the robot via bracket 9. The pressure in pressure tank 5 is controlled by the first air regulating valve 7, and the paint supply flow rate can be controlled by adjusting the pressure in pressure tank 5 using the first air regulating valve 7.

The spray pattern can be manually adjusted by adjusting the second air regulating valve 8.

[0037] The syringe-type feed tank 4 contains an injection piston 10. During the spraying process, as the paint decreases, the injection piston 10 always seals the paint inside the pressure tank under the action of compressed air.

Automatic on / off control of the spray gun is achieved via signals from the equipment.
