[0023] In another embodiment, if Figure 1 As shown, this embodiment discloses that a speed reducer 13 is provided on one side of the spline fixing seat 8, a swing arm transmission motor 14 is provided on the lower end surface of the speed reducer 13, a lifting and rotating spline 9 passes through the spline fixing seat 8, a lifting and rotating spline 9 is provided on the lower end surface of the lifting and rotating spline 9. The spline fixing seat 8 is connected to the speed reducer 13 through a synchronous belt, the output end of the swing arm transmission motor 14 is fixedly connected to the speed reducer 13, a lifting and transmitting motor 15 is provided on one side of the lifting and rotating Z-axis limiting sleeve 16, and the shape of the lifting and rotating Z-axis limiting sleeve 16 is cylindrical. By setting the swing arm transmission motor 14, the synchronous belt is also used to drive the R-axis nut to rotate the swing arm 10 (if it encounters a hard limit torque, the synchronous belt pulley starts to slip to prevent damage to the mechanism). By setting the lifting and transmitting motor 15, the lifting and rotating spline 9 is driven to rise and fall through the synchronous belt, which is convenient for subsequent processing and coating progress.

[0024] Working principle: During processing, first, the solvent is added to the solvent bottle 21 manually, a magnetic rod is placed in the solvent bottle 21, and the magnetic stirrer 7 drives the magnetic rod to stir continuously (speed is adjustable) to prevent precipitation of other substances in the solvent.

[0025] Furthermore, the high-speed rotating silicon wafer suction cup 5 fixes the product body 3 by vacuum adsorption to prevent the product body 3 from being thrown out during high-speed rotation. The PP bowl-shaped protective cover 1 is provided to protect and collect the solvent thrown out by the product.

[0026] Further, when the pen-holding tilt cylinder 12 is retracted, the writing brush is in a tilted posture, and when the pen-holding tilt cylinder 12 is extended, the writing brush is in a vertical posture.

[0027] Furthermore, when the equipment returns to the origin, the lifting transmission motor 15 drives the lifting rotating spline 9 through the synchronous belt, rises to the highest point and touches the Z-axis switch, and automatically returns to the soft limit origin to stop, and then starts the R-axis swing arm transmission motor 14. The swing arm transmission motor 14 also uses the synchronous belt to drive the R-axis nut to rotate the swing arm 10 to the right (if it encounters the hard limit torque, the synchronous belt pulley starts to slip to prevent damage to the mechanism); if the swing arm transmission motor 14 rotates to the fixed angle setting value and still cannot find the R-axis switch, it rotates in the opposite direction to find the switch position. After finding the switch position, it automatically returns to the soft limit origin to stop, and then the pen tilt cylinder 12 is extended to maintain the vertical pen holding method.

[0028] The last step is to set the Z-axis height to ensure that the brush is in a safe position above the solvent bottle 21, then set the angle of the swing arm 10 to center the brush with the bottle mouth, manually adjust the brush head to drop below the liquid level, keep 2 / 3 of the brush completely immersed, and set the brush dipping position: manually adjust the brush again to lift it to the bottle mouth position, adjust the swing arm 10 to make the brush stick to the bottle mouth to complete the pen licking action; lift the brush to a safe position, retract the pen tilt cylinder 12, and keep the brush in a tilted position, adjust the swing arm 10 to roughly center the brush head with the center of the product circle, set the Z-axis height to make the brush fit the product, ensure that the solvent can be coated on the product body 3, and then set the starting position of the swing arm 10 to complete the coating action of the circular product.

[0029] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
