Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a rapid curing device for circuit board processing. Background Technology

[0002] With the rapid development of electronic technology, electronic devices are constantly evolving towards miniaturization and high performance, which places higher demands on the manufacturing process of circuit boards. As the support for electronic components and the carrier of electrical connections, the production efficiency and quality of circuit boards directly affect the production cycle and performance of electronic devices. In the circuit board processing, the curing process is a crucial step.

[0003] However, existing rapid curing devices for circuit board processing usually use oven curing. Although the temperature can be controlled to a certain extent, the heating rate is slow and the heat distribution is uneven, which can easily cause inconsistent curing degrees in different parts of the circuit board. Furthermore, when cooling after curing, air cooling is usually used, but air cooling is difficult to control the cooling temperature, resulting in low cooling efficiency. Therefore, we propose a rapid curing device for circuit board processing. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a rapid curing device for circuit board processing, which has the following beneficial effects:

[0015] (1) This type of rapid curing device for circuit board processing, through the setting of a semiconductor cooling chip, a cooling fan, a drying fan, an infrared heating tube, and an ultraviolet curing lamp, when the circuit board is transported into the drying chamber, the infrared heating tube emits heat and acts on the circuit board, so that the circuit board reaches the temperature required for curing in a short time. At the same time, the drying fan operates to generate wind force, which acts on the infrared heating tube and forms hot air. At this time, the hot air acts on the circuit board, thereby playing a role in uniformly distributing heat. Meanwhile, the ultraviolet curing lamp emits ultraviolet light to further accelerate curing. After curing, the circuit board is transported into the cooling chamber. The heat emitted by the heating surface of the semiconductor cooling chip is discharged from the cooling cover through the cooling fan. When the cooling surface of the semiconductor cooling chip generates cold air, the cooling fan operates to generate suction to absorb the cold air, thereby reducing the temperature of the wind force. At this time, the wind force cools the circuit board, so that the rapid curing device for circuit board processing can uniformly distribute heat, ensuring that the curing degree of different parts of the circuit board is consistent, and also improving the curing efficiency and cooling efficiency.

[0023] Furthermore, a filter screen 14 is fixedly connected to the top of both the drying hood 13 and the cooling hood 15. The filter screen 14 is made of metal and serves to block dust, preventing dust from entering the drying chamber 11 and the cooling chamber 12.

[0024] Furthermore, a motor frame 4 is fixedly connected to one side of the base 2, and a conveyor motor 5 is installed on the top of the motor frame 4, which facilitates the installation of the conveyor motor 5 by the staff.

[0025] Furthermore, a drive wheel 6 is fixedly connected to the drive end of the conveyor motor 5, and a toothed belt 7 is movably connected to the outer side of the drive wheel 6. When the conveyor motor 5 is started, the conveyor motor 5 drives the toothed belt 7 to rotate through the drive wheel 6, and the toothed belt 7 drives the conveyor roller 8 to rotate through the transmission wheel 10.

[0026] Furthermore, a conveyor roller 8 is movably connected to the inner side of the conveyor 1, and a conveyor belt 9 is movably connected to the outer side of the conveyor roller 8. A drive wheel 10 is fixedly connected to one end of the conveyor roller 8, and the drive wheel 10 is movably connected to the toothed belt 7. When the toothed belt 7 drives the conveyor roller 8 to rotate through the drive wheel 10, the conveyor roller 8 drives the conveyor belt 9 to run. At this time, the conveyor belt 9 can transport the circuit board.

[0027] Furthermore, the bottom of the base 2 is fixedly connected with support legs 3. There are four support legs 3, which are located at the four corners of the bottom of the base 2. The support legs 3 make the curing device more stable.

[0028] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the rapid curing device for circuit board processing, the operator places the circuit board on the conveyor belt 9, then starts the conveyor motor 5. The conveyor motor 5 drives the toothed belt 7 through the drive wheel 6, and the toothed belt 7 drives the conveyor roller 8 through the transmission wheel 10. At the same time, the conveyor roller 8 drives the conveyor belt 9 to rotate. At this time, the conveyor belt 9 can transport the circuit board. When the circuit board is transported into the drying chamber 11, the infrared heating tube 21 emits heat and acts on the circuit board, so that the circuit board reaches the temperature required for curing in a short time. At the same time, the drying fan 19 operates. The airflow acts on the infrared heating tube 21, forming hot air. This hot air then acts on the circuit board, thus evenly distributing the heat. Simultaneously, the ultraviolet curing lamp 22 emits ultraviolet light to further accelerate curing. After curing, the circuit board is transported to the cooling box 12. The heat emitted from the heating surface of the semiconductor cooling chip 17 is exhausted from the cooling cover 15 through the heat dissipation fan 16. When the cooling surface of the semiconductor cooling chip 17 generates cold air, the cooling fan 18 operates to generate suction to absorb the cold air, lowering the temperature of the airflow. At this point, the airflow cools the circuit board, thus completing the usage process of this utility model. This utility model has a simple structure and is safe and convenient to use.
