A rubber pad is arranged in the middle of the support plate 16.

The first threaded shaft 6 is rotatably connected to one side of the base 1, and the second sliding plate 10 is threadedly connected to the surface of the first threaded shaft 6. One end of the first threaded shaft 6 is fixedly connected to the first synchronous wheel 8. A first servo motor 7 is arranged inside one end of the base 1, and the output end of the first servo motor 7 is fixedly connected to the first synchronous wheel 8. The two groups of first synchronous wheels 8 are connected by a synchronous belt. A sliding rod is arranged on the other side of the base 1, and the second sliding plate 10 is slidably connected to the surface of the sliding rod. The first servo motor 7 drives the first threaded shaft 6 to rotate through the first synchronous wheel 8 and the synchronous belt, so that the second sliding plate 10 slides back and forth with the first sliding plate 9 in the middle of the base 1.
[0031] Working principle: When in use, the connecting pipe 29 is connected to the external inkjet raw material box, and the first cylinder 15 is used to push the support plate 16 upward to place the thermometer in the middle of the support plate 16. The rubber pad in the middle of the support plate 16 can prevent the thermometer from slipping. Then the second servo motor 14 drives the second threaded shaft 12 to rotate clockwise through the second synchronous wheel 13, so that the two groups of sliding splints 11 on each group of second threaded shafts 12 are close to each other, and the upper end of the sliding splint 11 clamps the thermometer. The first servo motor 7 drives the first threaded shaft 6 to rotate through the first synchronous wheel 8, so that the second sliding plate 10 brings the first sliding plate 9 to slide along the first threaded shaft 6 and the slide rod. When the thermometer slides to the spray module 3 and the paint blocking module 4, the first servo motor 7 stops rotating, and the third servo motor 1 7 drives the third threaded shaft 18 to rotate clockwise, the mounting frame 19 slides along the third threaded shaft 18 toward the middle of the base 1, the mounting frame 19 drives the first baffle 20 and the paint spraying frame 25 to slide toward the thermometer, when the mounting frame 19 slides the maximum distance, the third servo motor 17 stops rotating, and at the same time the fourth servo motor 22 drives the fourth threaded shaft 23 to rotate, the sliding block 24 slides along the fourth threaded shaft 23 toward the middle of the base 1, the sliding block 24 drives the second baffle 33 toward the thermometer, when the sliding block 24 slides to the maximum distance, the fourth servo motor 22 stops rotating, the third servo motor 17 and the fourth servo motor 22 stop rotating at the same time, the second cylinder 31 pushes the second baffle 33 upward, so that the second baffle 33 is closer to the thermometer, and the paint spraying enters from the connecting pipe 29. The inside of the connecting frame 28 is connected, and the paint is sprayed from the nozzle 30 to the thermometer to complete the scale spraying. During the spraying process, the LED lamp 27 emits a bright light, and the visual detector 26 can observe whether the thermometer spraying is completed correctly. If the spraying is defective, the defect result will be transmitted to the external controller to remind the worker that there is a thermometer spraying error. When the nozzle 30 is spraying the thermometer, the excess paint will be blocked by the second baffle 33. At the same time, the sputtered paint will be blocked by the first baffle 20 to prevent the paint from polluting the device. After the spraying is completed, the third servo motor 17 drives the third threaded shaft 18 to rotate counterclockwise, and the fourth servo motor 22 drives the fourth threaded shaft 23 to rotate counterclockwise, so that the first baffle 20 and the second baffle 33 return to their original positions, and the first servo motor 7 drives the first threaded shaft 6 to rotate counterclockwise, so that the second sliding plate 10 drives the first sliding plate 9 to slide back. When the first sliding plate 9 slides to the position facing the drying module 5, the first servo motor 7 stops rotating, and drives the fan blade 40 to rotate through the nozzle 30, so that the air is accelerated to be ejected from the ventilation slot outlet, and the ejected air flows along the wind shield plate 35 toward the thermometer. The air entering the ventilation slot is heated by the heating tube 37, and the temperature is increased, so that the paint on the thermometer can be dried faster. Then the first servo motor 7 drives the first sliding plate 9 back to the original position, and pushes the support plate 16 upward through the first cylinder 15, so that the support plate 16 supports the thermometer. Then the second servo motor 14 rotates counterclockwise to make the sliding clamping plate 11 slide in the direction away from each other, thereby sending the thermometer away.Let the thermometer fall onto the support plate 16 to facilitate the removal of the thermometer, then place the thermometer to be coded in the middle of the support plate 16, repeat the above operation, and code the thermometer.
