[0057] like Figure 1 As shown, the aforementioned automatic spraying equipment includes a machine base 1, a work platform 2, a work station carrier 3, a cleaning and barcode scanning module 4, a flash spraying module 5, and a spraying module 6. The work station carrier 3, cleaning and barcode scanning module 4, flash spraying module 5, and spraying module 6 are mounted on the machine base 1. The work platform 2 is located on one side of the machine base 1 and is used for starting and stopping the equipment. The work station carrier 3 can be moved to the work platform 2. The operator stands on the work platform 2 to load the product. After the work station carrier 3 is supported and fixed, the operator manually presses the start button. The work station carrier 3 then moves to the cleaning and barcode scanning module 4, which scans the product's barcode (a QR code is affixed to the product surface; the QR code represents the product code and can display information about the product during the production process). (Uploaded to the system), simultaneously, the workstation carrier 3 flips the product to face the cleaning end of the cleaning and scanning mechanism 4. The cleaning and scanning mechanism 4 cleans the surface of the product to be sprayed (plasma cleaning). Then, the workstation carrier 3 transfers the product to the spraying module 6. Similarly, the workstation carrier 3 flips the product so that the surface to be sprayed faces the spraying end of the spraying module 6. The spraying module 6 sprays the product. Finally, the flash spraying module 5 flash sprays and cleans the nozzle of the spraying module 6. It should be noted that in this embodiment, a watch case is selected as the product to be produced. Of course, other products can be used in other embodiments. In addition, the equipment is covered with a machine cover to ensure a clean production environment and ensure production safety.

[0058] like Figure 2 As shown, the workstation carrier 3 includes a U-shaped base 31, a first driving member 32, a rotating platform 33, a second driving member 34, and a fixed seat 35. The U-shaped base 31 is slidably connected to the machine base 1 via a track, with the opening of the U-shaped base 31 facing upwards. The two ends of the rotating platform 33 are rotatably connected to the two ends of the opening of the U-shaped base 31. The first driving member 32 is used to drive the rotating platform 33 to rotate. The second driving member 34 is located at the bottom of the rotating platform 33. The fixed seat 35 is located above the rotating platform 33 and at the driving end of the second driving member 34. The second driving member 34 can drive the fixed seat 35 to rotate.

[0059] like Figure 3As shown, the fixed base 35 includes a fixed base 351 and a positioning member 352. The base 351 is located at the driving end of the second driving member 34, and the positioning member 352 is fixedly connected to the base 351. The positioning member 352 is used to fix the product. Specifically, the positioning member 352 includes a positioning block 3521 and an inner support member 3522. The surface of the positioning block 3521 is provided with a cross-shaped groove, wherein one end of the cross-shaped groove is open. The inner support member 3522 is a cross-shaped plate with a groove in the center of the positioning block 3521. Inside, the end face of the inner support member 3522 at the opening of the groove matches the end face of the part that abuts against the product. This end face is slightly longer than the positioning block 3521. An elastic member is provided between the other end of this end face and the positioning block 3521. The elastic member makes the outward end face of the inner support member 3522 tend to detach from the positioning block 3521. The product can be fitted onto the positioning block 3521 to achieve the initial positioning of the product. The inner support member 3522 tightens the positioning block 3521 inside the product to achieve precise positioning.

[0060] like Figure 4 As shown, the cleaning and scanning module 4 includes a support frame 41, a cleaning unit 42, and a scanning unit 43. The support frame 41 spans across the workstation carrier 3 and the moving track on both sides. The cleaning unit 42 and the scanning unit 43 are mounted on the support frame 41. The cleaning unit 42 performs plasma cleaning on the product, and the scanning unit 43 scans the product. The scanning unit 43 includes a connecting rod 431 and a scanning component 432. The connecting rod 431 is fixedly mounted on the support frame 41, and the scanning component 432 is mounted on the connecting rod 431 by a loosely adjustable fastener. The position of the scanning component 432 on the connecting rod 431 can be adjusted by loosening or tightening, thereby enabling scanning of QR codes at different positions.

[0061] like Figure 5 As shown, the spraying module 6 includes a three-axis drive unit 61, a spraying component 62, and a curing component 63. The three-axis drive unit 61 is mounted across the work station carrier 3 and the moving track via a gantry frame. The spraying component 62 and the curing component 63 are located at the drive end of the three-axis drive unit 61. The spraying component 62 can spray the product, and the curing component 63 can cure the sprayed product. Then, the three-axis drive unit 61 moves the spraying component 62 to the flash spraying module 5 for flash spraying.

[0062] like Figure 6 As shown, the flash spray module 5 includes a flash spray base 51, a propulsion platform 52, a water tank 53, and a flash spray component (not shown in the figure). The flash spray base 51 is located on one side of the spraying module 6. The propulsion platform 52 is slidably connected to the flash spray base 51. The water tank 53 is located on the propulsion platform 52, and the nozzle is located in the water tank 53. Specifically, after the spraying module 6 finishes spraying, the nozzle moves to the top of the flash spray module 5, and the propulsion platform 52 moves out to the flash spray component located below the nozzle. The flash spray component performs flash spraying on the nozzle to remove the ink adhering to the nozzle surface.

[0063] In summary, the spraying module 6 needs to spray the side of the product. When the product is loaded onto the work station carrier 3, it is placed flat. The surface to be sprayed is the side. The first drive unit 32 can drive the product to rotate, placing the side of the product in the vertical direction. Then, the second drive unit 34 drives the product to rotate, passing the side of the product under the nozzle in sequence. By allowing rotation, the sprayed coating layer is made more uniform.

[0064] The above description is only a preferred embodiment of an automatic spraying device disclosed in this utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept, and these all fall within the protection scope of this utility model.
