When performing coating work, first connect the entire device to an external power source, so that the liquid level sensor 27, infrared transmitter 35, infrared sensor 41 and piezoelectric sensor 42 are energized and started at the same time, and then the insulation cup that needs to be sprayed The mouth is placed between the two adjacent first arc-shaped clamping members 33 and the second arc-shaped clamping member 34 on the feeding conveyor belt 28; The feeding drive shaft 29 rotates, the feeding drive shaft 29 rotates and then drives the feeding conveyor belt 28 to move, and the movement of the feeding conveyor belt 28 drives the feeding driven shaft 30 to rotate, so that the feeding conveyor belt 28 can move cyclically; The movement of the material conveyor belt 28 will drive the first arc-shaped clamping member 33 and the second arc-shaped clamping member 34 to move, so as to slowly move the insulated cup between the first arc-shaped clamping member 33 and the second arc-shaped clamping member 34 Transfer to the side of the lower turntable 4; when the first arc-shaped clip 33 slowly approaches the paint holder 9, the infrared light emitted by the infrared emitter 35 on the first arc-shaped clip 33 will be on the paint holder 9. When the infrared sensor 41 receives it, the infrared sensor 41 will send a signal to the controller (the controller can be located on the side wall of the mounting frame 1, and its model is FX2C-20MRD, Cortex-R8, or Cortex-M7, etc. Programmable controller, used to control the start and stop of the whole device at different positions), the controller will first control the servo motor 19 to start positively for a certain period of time. After the servo motor 19 is started, it will drive the ball screw 18 to rotate, and the ball screw 18 The rotation will drive the moving block 20 to move, so that the moving block 20 will slowly move from above the paint holder 9 to above the end of the feeding conveyor belt 28; then the controller controls the lifting cylinder 21 to start, the electromagnet 23 is energized, and lifts. After the cylinder 21 is activated, it will drive the ejector rod 22 to slowly move down the surface of the feeding conveyor belt 28 and contact the bottom surface of the thermos cup. When the electromagnet 23 is energized, a magnetic field will be generated to attract the thermos cup; The lifting cylinder 21 stops. After the lifting cylinder 21 stops, the top rod 22 will slowly move upward, thereby taking out the thermos cup from between the first arc-shaped clip 33 and the second arc-shaped clip 34; Control the servo motor 19 to reverse for a certain period of time (the time of reverse rotation is the same as the time of forward rotation). After the servo motor 19 is started, it will drive the ball screw 18 to rotate. The rotation of the ball screw 18 will drive the moving block 20 to move. The moving block 20 slowly moves from above the end of the feeding conveyor belt 28 to directly above the paint holder 9 and makes the axis of the ejector rod 22 and the axis of the paint holder 9 on the same vertical line; then control the lifting again The air cylinder 21 is activated, so that the ejector rod 22 drives the thermos cup to slowly move to the paint holder 9, and makes the mouth of the thermos cup pass through the support rod 11 and is fixed in the fixed ring plate 14; at the same time, as the ejector rod 22 continues to move, The bottom end of the sealing cover 7 is in contact with the top surface of the fixed ring plate 14, because the edge of the bottom surface of the sealing cover 7 is provided with a clamping block, and the top surface of the fixed ring plate 14 is provided with a clamping groove, so that the sealing cover 7 can be tightly connected with the fixed ring plate 14 to form a coating space in the fixed ring plate 14; then the torque motor 3 and the negative pressure machine 24 are controlled to start, and the negative pressure machine 24 will pass through the negative pressure tube 25 and negative pressure after the start The ring tube 26 evacuates the coating space, so that the pressure in the coating space is reduced, so that the coating liquid in the storage cavity 10 will enter the coating space through the discharge hole 15 to affect the insulation of the thermos cup. The outer wall is coated; at the same time, part of the coating liquid will enter between the support rod 11 and the inner wall of the insulation cup through the flow cavity 12 and the outflow hole 13 on the support rod 11, and then spray the inner wall of the insulation cup to achieve Coating inside and outside at the same time improves work efficiency; when the torque motor 3 is started, the torque motor 3 will drive the driving rod 2 to rotate, and the rotation of the driving rod 2 will drive the upper turntable 4 and the lower turntable 4 to rotate, thereby making the paint holder with a thermos cup 9 leaves from the side of the feeding device 14, and the empty paint holder 9 will slowly move from the feeding device 15 to the side of the feeding device 14, so as to carry out the cyclic loading and unloading mode, and the entire device area is reduced. ; During the coating process, as the coating liquid in the coating space slowly rises, the coating liquid will contact the bottom end of the sealing cover 7, and then the liquid level sensor 27 will send out an electrical signal to control the negative pressure The machine 24 stops working; after the negative pressure machine 24 stops for a period of time, the lifting cylinder 21 is controlled to stop, so that the ejector rod 22 can take the thermos cup out of the fixed ring plate 14 through the electromagnet 23 and drive it to move upward; The movement of 22 will also drive the sealing cover 7 to move, so that the sealing cover 7 is separated from the fixed ring plate 14, so that the pressure in the coating space returns to the same external pressure. At this time, the coating liquid in the coating space and the insulation cup The coating liquid will return to the storage cavity 10 along the discharge hole 15 for reuse; at the same time, the external air can dry the inside of the thermos cup, and the rotation of the upper turntable 5 makes the air flow outside the thermos cup. The speed increases, thereby accelerating the rate of drying.

As the torque motor 3 drives the lower turntable 4 to move, the lower turntable 4 will slowly move to the side of the blanking plate 36. At this time, the line on the blanking plate 36 will contact the piezoelectric sensor 42. The piezoelectric sensor 42 will send an electrical signal to the controller, and the controller will control the servo motor 19 to start up for a certain period of time. After the servo motor 19 is started, it will drive the ball screw 18 to rotate, and the ball screw 18 will rotate to drive the moving block 20. Move, so that the moving block 20 slowly moves from the top of the paint base 9 to the top of the blanking plate 36, and then control the lifting cylinder 21 to start again, so that the top rod 22 drives the thermos cup to slowly move to the blanking plate 36 Then, the electromagnet is de-energized, so that the ejector rod 22 is separated from the insulated cup, and finally the lifting cylinder 21 is controlled to stop, so that the ejector rod 22 returns to the initial position, and the blanking is completed. Because the blanking plate 36 is arranged in an oblique shape, the vacuum cup that enters the blanking plate 36 will slowly move to the direction of the blanking channel 37, and the guide plate 38 will guide the movement of the multiple vacuum cups during the movement. At the same time, under the mutual cooperation of the guide plate 38, the positioning plate 39 and the side wall of the blanking plate 36, a plurality of disorderly insulated cups are slowly transformed into a single orderly arrangement and moved to the blanking channel 37, thereby It is convenient for subsequent organization; at the same time, when working, start the stirring motor 45. After the stirring motor 45 is started, it will drive the stirring rod 43 to rotate. The coating liquid inside is uniformly stirred, and no additional coating liquid stirring device is required, which further reduces the floor space; there is no need to transport the coating liquid, which reduces labor intensity.
