Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figure 1-3A waterborne polyurethane coating spraying device includes a processing table 1, a pair of workstation units 2, a motion unit 3, a vision inspection unit 4, a spraying unit 5, and a feeding unit 6. The workstation unit 2 includes a feeding servo rail 21, a carrier 22 is mounted on the slider of the feeding servo rail 21, and a sealing ring is mounted on the carrier 22. The spraying unit 5 is mounted on the motion unit 3 and moves in the XZ axis direction through the motion unit 3. The spraying unit 5 is connected to the feeding unit 6. The vision inspection unit 4 includes a pair of vision inspection cameras 41 and an inspection device 42, with the vision inspection cameras 41 mounted above the carrier 22. Specifically, a sealing ring is placed on one of the carriers 22, and it moves to the workstation under the action of the feeding servo rail 21. The spraying unit 5 performs spraying under the action of the motion unit 3. After the spraying is completed, it is visually inspected by the vision inspection unit 4. During this process, the other workstation unit 2 feeds materials and then completes the above operations. In this way, the two workstation units 2 take turns to enter and exit to perform spraying and visual inspection, thereby improving the spraying quality, spraying efficiency, inspection quality and inspection efficiency. The inspection equipment 42 has a built-in vision inspection system for inspecting and judging the images captured by the vision inspection camera 41. The feeding unit 6 feeds materials to the spraying unit 5.

[0021] In this embodiment, the motion unit 3 includes a pair of columns 31, with an X-axis servo rail 32 mounted on the columns 31. A Z-axis servo rail 33 is longitudinally mounted on the slider of the X-axis servo rail 32, and a spraying unit 5 is mounted on the slider of the Z-axis servo rail 33. The spraying unit moves in the X-axis direction and the Z-axis direction under the action of the X-axis servo rail 32 and the Z-axis servo rail 33. The main function of the X-axis servo rail 32 is to move the spraying unit between the two carriers 22, and the main function of the Z-axis servo rail 33 is to move the spraying unit downwards, cooperating with the X-axis servo rail 32 to perform alternating spraying.

[0022] In this embodiment, the spraying unit 5 is a spray valve. The atomizing air pressure of the spray valve is controlled at around 2 bar, and the nozzle diameter of the spray gun is controlled within the range of 0.8-1.4 mm to ensure uniform coating and avoid over-spraying and backsplashing.

[0023] In this embodiment, the feeding unit 6 includes a pressure tank 61, a stirring motor 62 mounted on the pressure tank 61, a stirring rod (not shown) mounted on the output shaft of the stirring motor 62, and stirring blades (not shown) mounted on the stirring rod. A glue supply pipe (not shown) is mounted on the output end of the pressure tank 61 and connects to the spraying unit 5. The stirring motor 62 is a servo motor, which can adjust the stirring speed of the glue. A liquid level sensor is installed inside the pressure tank 61 to remind the user to add material when the liquid level is low.

[0024] In this embodiment, a flow sensor (not shown in the figure) is installed on the glue supply pipeline. The flow sensor monitors changes in flow rate during production, and promptly stops the spraying operation and alerts the operator when glue blockage occurs.

[0025] In this embodiment, ultraviolet lamps 43 are arranged on the left and right sides of the visual inspection camera 41. The ultraviolet lamps 43 work in conjunction with the visual inspection camera 41 to improve the inspection quality of the visual inspection camera 41.

[0026] See Figure 3 It also includes an external protective structure 7, with an inlet / outlet port 71 on the front. The external protective structure protects the internal workstation unit 2, motion unit 3, vision inspection unit 4, and spraying unit 5; the inlet / outlet port 71 allows materials to enter and exit.
