[0041] In the coating equipment applied in this case, the coating bracket 1 is directly on the ground, the protective shell 2 is installed on the periphery of the coating bracket 2, and the coating actuator 3, the visual positioning assembly mechanism 9, the left and right positioning side-pushing assembly mechanism 4, the top side positioning side-pushing assembly mechanism 5, the bottom conveyor line assembly mechanism 6, the feed positioning mechanism 7, and the jacking positioning assembly mechanism 8 are respectively installed on the coating bracket 1 and are located inside the protective shell 2. Inside the coating bracket 1, the visual positioning assembly mechanism 9 is located above the coating actuator 3, the left and right positioning side-pushing assembly mechanism 4 is located below the visual positioning assembly mechanism 9, the top side positioning side-pushing assembly mechanism 5 is located below the left and right positioning side-pushing assembly mechanism 4, the bottom conveyor line assembly mechanism 6 is located below the top side positioning side-pushing assembly mechanism 5, and the feed positioning mechanism 7 is arranged above the bottom conveyor line assembly mechanism 6.

[0042] The coating robot is connected to the coating actuator 5, and the whole equipment is mainly composed of a protective shell 2, a feeding mechanism 7, a lifting and positioning assembly mechanism 8, a side push mechanism, a visual positioning assembly mechanism 9, a coating robot and a coating actuator 5. The protective shell 2 mainly plays a role in safety protection. The feeding mechanism 7, as the first station of the equipment, plays the role of lifting, guiding and positioning the feeding product. The lifting and positioning assembly mechanism 8 is to lift the product from the feeding and positioning mechanism of the assembly line to the predetermined coating position with a vertical force. The side positioning side push assembly mechanism 5 and the left and right positioning side push assembly mechanism 4 are mainly to further position and align the product so that the product can accurately stay in the coating position.

The robot action drives the coating actuator to apply the primer. At this point, the action of the entire mechanism is completed.

[0043] In the coating actuator, the bottom end of the spray valve support plate 304 is provided with a spray nozzle 308 and a detection laser controlled by a controlled spray valve 305. The spray valve 305 adopts a completely positioned mode and uses a distance sensor 306 to calibrate the height. The end of the spray valve support plate 304 uses a height detection laser to detect the height. Thus, the distance from the coating surface can be automatically adjusted to achieve real-time detection of the spray nozzle position height, thereby ensuring that the thickness of the coated primer is uniform and the primer does not overflow, thereby achieving a coating effect. In addition, because the spray nozzle 308 is controlled by the spray valve 305, if there is a colloid left on the sprayed surface, the spray valve 305 drives the spray nozzle 308 to clean the spray valve 305 to avoid the phenomenon of glue pulling, thereby achieving the purpose of neat coating. Because the glue line in the coating actuator 3 is detected in real time, if the detected glue line is interrupted, a glue break alarm is triggered. In addition, the visual positioning component mechanism 9 disposed on the coating bracket 1 adopts a binocular high-precision CCD camera with 20 million pixels and high shooting accuracy, so that fast and accurate positioning can be achieved. In addition, the structures of the sky-side positioning side-pushing component mechanism 5 and the left-right positioning side-pushing component mechanism 4 are reliable, so that the push wheel can avoid damaging the product.

[0044] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but the scope of the present invention is not limited by this. Any modification, equivalent substitution and improvement made by a person skilled in the art without departing from the scope and essence of the present invention shall be within the scope of the present invention.
