[0023] Reference Figures 1-4 A keyboard surface painting device includes a base plate 5, a U-shaped frame 7 fixed to the upper surface of the base plate 5 by bolts, and a movable painting component on the top of the U-shaped frame 7.

[0024] The painting assembly includes a paint box 1, which is fixed to the upper surface of a U-shaped frame 7 by bolts. A paint pump is fixed on the paint box 1. The paint pump is a gear pump, Y-PUMP 5ccRPN. The inlet pipe of the paint pump is sealed and inserted into the paint box 1. The outlet pipe of the paint pump is sealed and inserted into a T-shaped pipe. The two ends of the T-shaped pipe are sealed and connected to two corrugated pipes 2. A groove 10 is opened on the top of the U-shaped frame 7. Two sliders 8 are slidably connected in the groove 10. The bottom of the sliders 8 is detachably connected to a nozzle 11 by bolts. The bottom end of the corrugated pipe 2 is fixed to the slider 8 at the corresponding position. The corrugated pipe 2 passes through the groove 10 and is sealed and connected to the nozzle 11 at the corresponding position. The nozzle 11 is an HVLP high-efficiency low-pressure spray gun. The model can be selected as SATAjet 150B. When the gear pump is working, the paint material in the paint box 1 enters the nozzle 11 through the corrugated pipe 2 and is sprayed out.

[0025] The U-shaped frame 7 is equipped with a drive assembly that moves the slider 8. The length of the bellows 2 is suitable for the movement range of the drive assembly. The drive assembly includes two support plates, which are fixed to the outer walls on both sides of the U-shaped frame 7. An electric push rod 6 is fixed to the upper surface of the support plate by bolts, and the extended end of the electric push rod 6 is fixed to the slider 8 at the corresponding position. The extension and retraction of the electric push rod 6 causes the slider 8 to move the spray head 11 along the slide 10, so that the spray head 11 moves back and forth to spray paint on the keyboard below. The maximum extension distance of the electric push rod 6 is in the middle area of ​​the slide 10. The two electric push rods 6 will not collide, and the two electric push rods 6 can be controlled independently.

[0026] A T-block 13 is fixed to the upper surface of the base plate 5 by bolts. A slide block 12 is slidably connected to the outside of the T-block 13, and the T-block 13 can guide the slide block 12.

[0027] The upper surface of the base plate 5 is provided with a power component that drives the slide 12 to move. The power component includes a cylinder 15. The cylinder 15 is fixed to the middle of the upper surface of the base plate 5 by bolts. One end of the piston rod of the cylinder 15 is fixed to the slide 12. In particular, a corrugated cover is sleeved on the extended end of the cylinder 15. Both ends of the corrugated cover are fixed to the slide 12 and one end of the cylinder 15 body to protect the extension rod and prevent paint from being sprayed onto the rod.

[0028] A paint collection trough is provided on the upper surface of the base plate 5, and a paint drain pipe is sealed and inserted into the paint collection trough.

[0029] In particular, the upper surface of the slide 12 is fixed with a fixing frame 4 by bolts. Two rotating shafts are rotatably connected to the fixing frame 4. The top of each rotating shaft is welded with a connecting plate 16. The upper surface of the connecting plate 16 is detachably connected with a placement plate 14 by bolts. The detachable method makes it convenient for staff to maintain and replace the placement plate 14. The keyboard is placed in the groove on the placement plate 14, and the cylinder 15 is activated to push the slide 12 to the middle position inside the U-shaped frame 7.

[0030] The bottom of the mounting bracket 4 is equipped with a power component that drives the rotating shaft to rotate. The power component includes a motor 18, which is fixed to the bottom of the mounting bracket 4 by bolts. The bottom of the mounting bracket 4 is rotatably connected to a rotating shaft. Both rotating shafts and the bottom ends of the rotating shafts are keyed to pulleys 17. The multiple pulleys 17 are connected to each other by a synchronous belt 19. One end of the output shaft of the motor 18 is fixed to the rotating shaft. The rotation of the motor 18, through the cooperation of the pulleys 17 and the synchronous belt 19, enables the rotating shaft to drive the placement plate 14 on the connecting plate 16 to rotate 360 ​​degrees, so that the keyboard surface is evenly sprayed with paint.

[0031] Working principle: When it is necessary to spray paint on the keyboard surface, first place the keyboard in the groove on the placement plate 14, start the cylinder 15, push the slide 12 to the middle position inside the U-shaped frame 7, and the paint pump makes the paint material in the paint box 1 enter the nozzle 11 through the corrugated pipe 2 and spray it out.

[0032] Start the electric push rod 6. The electric push rod 6 extends and retracts, causing the slider 8 to move the nozzle 11 along the slide 10, so that the nozzle 11 moves back and forth to spray paint on the keyboard below.

[0033] Simultaneously, the motor 18 is started. The rotation of the motor 18, through the cooperation of the pulley 17 and the synchronous belt 19, enables the shaft to drive the placement plate 14 on the connecting plate 16 to rotate 360 ​​degrees, so that the keyboard surface is evenly sprayed with paint; after the paint is sprayed, wait for it to dry.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that the top of the U-shaped frame 7 has two slots 3, and a fan 9 is fixed in each of the two slots 3 by bolts. The model can be HS-E420H. After the paint is fixed, the fan 9 can be turned on to generate airflow to accelerate the drying of the painted keyboard.
