Description

Technical Field

[0001] This utility model relates to the field of power adapter manufacturing technology, specifically to a shell painting device for power adapter manufacturing. Background Technology

[0002] A power adapter is a power conversion device for portable electronic devices or appliances. Power adapters are generally small in size and easy to carry. They usually consist of a casing and other electronic components such as a transformer. The casing protects the electronic components. During the production of power adapters, the casing needs to be treated with a casing painting device to improve the service life of the casing.

[0003] In existing technologies, when spraying paint on the casing of a power adapter, the casing is usually fixed and then coated on the surface of the casing using a spray nozzle. However, this coating method has coating dead spots. After coating, the power adapter needs to be manually adjusted and coated again, resulting in poor coating effect. Therefore, a casing painting device for power adapter production is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please refer to the following: Figures 1-4This utility model provides a technical solution: a shell painting device for power adapter production, including a spray painting table 1 and a turntable 2. Multiple sets of hollow vertical plates 3 arranged in a circular array are fixedly connected to the top outer surface of the turntable 2. Each set of hollow vertical plates 3 consists of two plates, and a rotating shaft is rotatably connected between the two plates in each set. A rotating frame 4 is fixedly fitted onto the outer surface of the rotating shaft. Vertical plates are fixedly connected to the top and bottom outer surfaces of the rotating frame 4. A first electric push rod 5 is fixedly installed on the outer surface of the vertical plate. An L-shaped plate is fixedly connected to the output end of the first electric push rod 5. A second electric push rod 6 is fixedly installed on the outer surface of the L-shaped plate. An electric suction cup 7 is fixedly installed at the output end of the second electric push rod 6. A third electric push rod 9 is fixedly installed on the outer surface of one of the hollow vertical plates 3. A rack 10 is fixedly connected to the output end of the third electric push rod 9. A first gear 8 is fixedly fitted onto the outer surface of the rotating shaft. The rack 10 movably meshes with the outer surface of the first gear 8. Specifically... The power adapter casing is secured. Then, the first electric push rod 5 is activated, moving the L-shaped plate, which in turn moves the electric suction cup 7. The second electric push rod 6 moves the electric suction cup 7 upwards, adsorbing and securing the bottom of the power adapter casing. The first and second electric push rods 5 and 6 work together to move the electric suction cup 7 to hold the power adapter casing in place. The third electric push rod 9 moves the rack 10, with a stroke of L (L = π*r), where r is the radius of the first gear 8. The rack 10 rotates the first gear 8, causing the rotating frame 4 to rotate 180 degrees, turning the bottom of the power adapter casing upwards. It is then rotated below the spray nozzle 18 to spray the unpainted areas of the power adapter casing, enabling continuous painting without the need for manual removal and re-securement of the power adapter casing, thus improving painting efficiency.

[0022] In this embodiment, a first fixing frame 11 is fixedly connected to the top outer surface of the spray booth 1. A fourth electric push rod 12 is fixedly installed on the top downward outer surface of the first fixing frame 11. A connecting plate 13 is fixedly connected to the output end of the fourth electric push rod 12. A connecting pipe 14 is fixedly connected to the bottom outer surface of the connecting plate 13. The other end of the connecting pipe 14 is connected to a rotary joint 15. The other end of the rotary joint 15 is connected to a conveying pipe 16. An L-shaped pipe 17 is fixedly connected to the outer surface of the conveying pipe 16. Several nozzles 18 are connected to the outer surface of the L-shaped pipe 17. Specifically, the fourth electric push rod 12 drives the L-shaped pipe 17 to move downward. An external conveying pump conveys paint into the connecting pipe 14, and then enters the conveying pipe 16 through the rotary joint 15 and finally enters the L-shaped pipe 17. The corresponding number of nozzles 18 are turned on as needed, so that the nozzles 18 spray paint onto the surface of the power adapter housing.

[0023] In this embodiment, a first motor 20 is fixedly installed on the bottom outer surface of the connecting plate 13, a second gear 19 is fixedly sleeved on the outer surface of the connecting pipe 14, and a third gear 21 is fixedly sleeved on the output end of the first motor 20. The outer surfaces of the second gear 19 and the third gear 21 are movably meshed. Specifically, the first motor 20 drives the third gear 21 to rotate, and the third gear 21 drives the second gear 19 to rotate, thereby driving the connecting pipe 14 to rotate the L-shaped pipe 17.

[0024] In this embodiment, a second fixing frame 22 is fixedly connected to the top outer surface of the spray painting station 1 at a position perpendicular to the first fixing frame 11. An air outlet duct 23 is fixedly connected to the top outer surface of the second fixing frame 22. Specifically, an external hot air blower delivers hot air to the air outlet duct 23 and blows the hot air onto the surface of the power adapter shell after it has been painted, so as to dry it.

[0025] In this embodiment, a rotating cylinder 24 is rotatably connected to the top outer surface of the spray booth 1, and a second motor 25 is fixedly installed on the bottom outer surface of the spray booth 1. A fourth gear 26 is fixedly connected to the output end of the second motor 25, and a fifth gear 27 is fixedly sleeved on the outer surface of the rotating cylinder 24. The outer surfaces of the fourth gear 26 and the fifth gear 27 are movably meshed. Specifically, the second motor 25 drives the fourth gear 26 to rotate, and the fourth gear 26 drives the fifth gear 27 to rotate, causing the rotating cylinder 24 to rotate, thereby driving the turntable 2 to rotate.

[0026] In this embodiment, multiple infrared receivers are installed on the top outer surface of the spray booth 1, and an infrared transmitter is installed on the bottom outer surface of the turntable 2. Both the infrared receivers and the second motor 25 are electrically connected to an external controller. Specifically, infrared rays are emitted through the infrared transmitters and received by the infrared receivers, and then the signals are sent to the controller, which controls the operation of the second motor 25.

[0027] Working Principle: In use, the power adapter housing is fixed. The first electric push rod 5 is then activated, moving the L-shaped plate, which in turn moves the electric suction cup 7. The second electric push rod 6 moves the electric suction cup 7 upwards, adsorbing and fixing the bottom of the power adapter housing. When the power adapter housing moves below the spray nozzle 18, an external delivery pump delivers paint to the connecting pipe 14, which then passes through the rotary joint 15 into the delivery pipe 16 and finally into the L-shaped pipe 17. The required number of spray nozzles 18 are activated. The first motor 20 drives the third gear 21 to rotate, which in turn drives the second gear 19. The second gear 19 then drives the delivery pipe 16, causing the L-shaped pipe 17 to rotate, which in turn rotates the spray nozzles 18, performing a comprehensive painting of the power adapter surface. After painting is complete, the second motor 25 drives the fourth gear 2... The fourth gear 26 rotates, driving the fifth gear 27 to rotate, causing the rotating drum 24 to rotate. This rotates the painted power adapter casing to below the air outlet 23, where a hot air blower delivers airflow onto the surface of the power adapter casing to dry the paint. Then, the first electric push rod 5 and the second electric push rod 6 work above, driving the electric suction cup 7 to pick up the power adapter casing. The third electric push rod 9 then drives the rack 10 to move, with a stroke of L, where L = π*r, and r is the radius of the first gear 8. The rack 10 drives the first gear 8 to rotate, causing the rotating frame 4 to rotate 180 degrees, rotating the bottom of the power adapter casing to face upwards. It is then rotated to below the spray nozzle 18 to spray the unpainted areas of the power adapter casing, thus enabling continuous painting without the need for manual removal and re-fixing of the power adapter casing, improving painting efficiency.

[0028] The controller is an existing structure, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
