[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as high-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. When targeting cylindrical capped products, it is necessary to spray the outside and inside of the product at the same time. During spraying, the product needs to rotate at a constant speed to ensure uniform spraying quality and to meet certain production requirements.

[0043] The rotating frame 20 can be rotatably arranged on the frame 10, and the rotating frame 20 extends outward to have stations 21 arranged at equal angles, and each station 21 includes a fixedly connected rotating arm 211 and a mounting plate 212. In this embodiment, a first driven gear 22 is arranged on the rotating frame 20. A mounting seat 11 for an external manipulator to be installed is arranged on the frame 10, and the mounting seat 11 is located above the rotating frame 20. The external manipulator with a second spray head 62 is arranged on the mounting seat 11, so as to complete the spraying process of the product outside the spraying station. Two cleaning components 12 are arranged on the frame 10, and the outer ends of the two cleaning components 12 correspond to the positions of the corresponding mounting plates 212 respectively. There are four workstations 21 arranged at equal angles, wherein the output end of one cleaning assembly 12 is located above the side of the fixed seat 40 on the corresponding mounting plate 212, thereby completing the cleaning process of the product on the fixed seat 40; the output end of another cleaning assembly 12 corresponds to the position of the fixed seat 40 on the corresponding mounting plate 211, thereby completing the cleaning process of the fixed seat 40. The frame 10 is provided with a sensor 13, and the rotating frame 20 is provided with a plurality of sensor sheets 23, each of which corresponds to the position of the corresponding workstation 21, and the sensor 13 is located above the plurality of sensor sheets 23. The sensor 13 senses the position of the sensor sheet 23 on the rotating frame 20 during the rotation of the rotating frame 20, and cooperates with the first driving assembly 30 to realize the accurate positioning of the rotation angle of the rotating frame 20.

[0044] The first driving assembly 30 is arranged on the frame 10 and drives the rotating frame 20 to rotate; in the present embodiment, the first driving assembly 30 comprises a first servo motor 31, a first reducer 32 and a first transmission gear 33; the first servo motor 31 is arranged on the frame 10, the first reducer 32 is connected to the output end of the first servo motor 31, the first transmission gear 33 is arranged at the output end of the first reducer 32 and is driven by the first reducer 32, and the first transmission gear 33 is meshed with the first driven gear 22.

[0046] The second drive assembly 50 can be movably arranged on the frame 10, and the output end of the second drive assembly 50 is matched or separated with the input end of the fixed seat 40 as the second drive assembly 50 moves. When the output end of the second drive assembly 50 is matched with the input end of the fixed seat 40, the fixed seat 40 is driven to rotate, so as to avoid the second drive assembly 50 passing through the first drive assembly 30, so that the first drive assembly 30 can drive the rotating frame 20 to rotate 360°, and the operation process of continuous stations such as product loading station, product cleaning station, product spraying station, and product unloading station can be realized in sequence. The second drive assembly 50 is set in multiple ways, and each second drive assembly 50 corresponds to the position of the corresponding station 21.

[0047] The second driving assembly 50 includes a movable plate 52, a first driving mechanism 53, a second servo motor 54, a second reducer 55 and a second transmission gear 56; the movable plate 52 can be movably arranged on the frame 10; the first driving mechanism 53 is arranged on the frame 10 and drives the movable plate 52 to move back and forth; the second servo motor 54 is arranged on the frame 10; the second reducer 55 is arranged on the frame and connected to the output end of the second servo motor 54; the second transmission gear 56 is arranged at the output end of the second reducer 55 and is driven back and forth by the second reducer 55, and the second transmission gear 56 is connected to the input end of the fixed seat 40. In this embodiment, the first driving mechanism 53 is a telescopic cylinder.

[0048] The working principle of this embodiment is described in detail as follows:

[0049] When spraying, first connect the equipment to the external power supply and the controller, then fix the product on the fixed seat 40 at the loading station, and after fixing, the cleaning component 12 cleans the product on the fixed seat 40. After cleaning, the first driving component 30 drives the rotating frame 20 to rotate, so as to rotate the product on the fixed seat 40 to the spraying station, and then the output end of the second driving component 50 at the spraying station moves to the side of the fixed seat 40 and meshes with the second driven gear 41 on the fixed seat 40, and the second driving component 50 drives the rotating frame 20 to rotate. The movable fixed seat 40 and the product on the fixed seat 40 rotate, and at the same time, the first nozzle 61 extends upward through the through hole 401 into the product to spray the inside of the product, and the second nozzle 62 sprays the outside of the product; after the spraying is completed, the second servo motor 54 stops working, and then the first drive mechanism 53 drives the second transmission gear 56 to disengage from the second driven gear 41, and drives the sprayed product to continue to rotate backward to the unloading station through the first drive component 30, and the unloading process of the product is completed by the external unloading mechanism. After unloading is completed, the first drive component 30 drives the fixed seat 40 to rotate to another cleaning component 12, and the cleaning process of the fixed seat 40 after unloading is completed by the cleaning component 12, and then the fixed seat 40 continues to rotate to the loading station, and the above steps are repeated.

[0050] The design focus of the present invention is that the second drive component can be movably arranged on the frame back and forth, and the output end of the second drive component cooperates or separates with the input end of the fixed seat as the second drive component moves, and drives the fixed seat to rotate when the output end of the second drive component cooperates with the input end of the fixed seat, so that the second drive component does not need to be fixed on the secondary rotating mechanism, and only needs to drive the fixed seat to cooperate with the input end of the fixed seat when rotating, and there is no need for the second drive component to pass through the first drive component, so that the first drive component can drive the rotating frame to rotate freely 360°, and the operation process of continuous stations such as product loading station, product cleaning station, product spraying station, and product unloading station can be realized. Not only is the use limitation smaller, but also the spraying operation process is made more convenient, effectively improving the efficiency of the overall spraying process.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
