Technical Field

[0001] This utility model relates to the technical field of energy-saving fan devices, and in particular to an energy-saving fan device used in the drying section of a PCB horizontal line. Background Technology

[0002] In the PCB (Printed Circuit Board) manufacturing industry, the drying section is a key process to ensure product quality. As the core equipment of the drying section, the performance of the fan unit directly affects production efficiency and energy consumption costs.

[0003] However, current PCB horizontal drying section fan devices on the market have many drawbacks. First, most fans operate in a constant power mode, unable to accurately adjust airflow based on dynamic changes in temperature and humidity during the drying process. This leads to significant energy waste during low-demand periods, resulting in high production costs for enterprises. Second, the airflow organization is unreasonable, lacking effective airflow adjustment methods, and the uneven airflow distribution causes inconsistent PCB drying results and increases the defect rate. Third, traditional devices have complex air intake filtration structures, making filter replacement and maintenance inconvenient. Therefore, improvements are needed. Utility Model Content

A limiting member 10 is fixedly mounted on the outer wall of the air inlet pipe 9, and a sealing gasket 11 is mounted on one side of the limiting member 10. The upper surface of the mounting plate 1 is fixedly... A fixing plate 13 is installed, and a PLC controller 14 is fixedly installed on the outside of the fixing plate 13. An exhaust pipe 15 is fixedly installed on the outer wall of housing 1 8. A connecting pipe 16 is installed at the end of the exhaust pipe 15 away from housing 1 8.

An airflow regulating mechanism 3 is installed on one side of housing 2 17. Quick-release mechanisms 4 are symmetrically installed on the outer wall of the filter element 12. The airflow regulating mechanism 3 includes a connecting plate 301 and a shaft 302. The outer wall of the shaft 302... A guide plate 303 is fixedly installed on the wall. A gear 304 is fixedly installed at one end of the shaft 302. A guide post 305 is fixedly installed on the inner side of the connecting plate 301. A second motor 306 is fixedly installed on the outer side of the connecting plate 301. A threaded rod 307 is fixedly installed at the output end of the second motor 306. A slider 308 is threadedly connected to the outer wall of the threaded rod 307. A toothed rod 309 is fixedly installed on one side of the slider 308. The sealing gasket 11 is slidably connected to the intake pipe 9. The rotating shaft 5 is rotatably connected to the housing 8. The filter element 12 is slidably connected to the intake pipe 9. The connecting pipe 16 is threadedly connected to the exhaust pipe 15 and the housing 17. The mounting plate 1 has symmetrical through-holes 20 on its upper surface. The mounting plate 1 is fixedly connected to the motor 2. There are three sets of shafts 302, guide plates 303 and gears 304. The three sets of gears 304 mesh with the rack 309. The three sets of shafts 302 are rotatably connected to the housing 17. There are two sets of connecting plates 301. The two sets of connecting plates 301 are fixedly connected to the housing 17. The slider 308 is slidably connected to the guide post 305. The PLC controller 14 is electrically connected to the temperature sensor 18, the humidity sensor 19, the motor 2 and the motor 306.

[0025] In this embodiment, the temperature sensor 18, humidity sensor 19, and PLC controller 14 are linked to sense changes in the drying environment in real time. Based on actual needs, the speed of motor 2 is intelligently adjusted to change the air volume of the fan, avoiding energy waste caused by traditional constant power operation. At the same time, in the innovative airflow adjustment mechanism 3, motor 2 306 drives the threaded rod 307 to drive the slider 308 and the rack 309 to move, thereby controlling the angle change of the three sets of guide plates 303, realizing precise adjustment of airflow direction and intensity. Compared with traditional devices that lack effective adjustment means, this design can make the air field distribution more uniform, ensure that all parts of the PCB board are heated evenly, effectively reduce the defect rate caused by uneven drying, and improve product quality and production efficiency.

[0026] Example 2: As Figure 2 and Figure 5 As shown, the quick-release mechanism 4 includes a round rod 401, a stop block 402 is fixedly installed at one end of the round rod 401, an L-shaped slide plate 403 is slidably connected to the outer wall of the round rod 401, a clamping ring 404 is fixedly installed at one end of the L-shaped slide plate 403, a spring 405 is sleeved on the outer wall of the round rod 401, there are two sets of round rods 401, the two sets of round rods 401 are fixedly connected to the filter element 12, the clamping ring 404 is engaged with the limiting member 10, one end of the spring 405 is fixedly connected to the stop block 402, and the other end of the spring 405 is fixedly connected to the L-shaped slide plate 403.

[0027] In this embodiment, the unique quick-release mechanism 4 allows the filter element 12 to be quickly removed by pulling the L-shaped sliding plate 403 to disengage the clamping ring 404 from the limiting member 10. After replacement, the spring 405 automatically resets and engages. The operation is simple and convenient. Compared with the traditional filter element 12 device with complex structure and cumbersome replacement, it greatly shortens the maintenance time, reduces the impact of equipment downtime maintenance on the production schedule, reduces labor maintenance costs, and improves the overall operating efficiency and stability of the equipment.

[0028] The working principle of this embodiment is as follows: In terms of intelligent control, the temperature sensor 18 and humidity sensor 19 monitor the environmental parameters of the drying section in real time and transmit the data to the PLC controller 14. The PLC controller 14 analyzes and judges according to the preset drying process parameters. When it detects that the temperature and humidity have not reached the set values, it controls the motor 2 to run at a higher speed, driving the shaft 5 and impeller 6 to rotate at high speed, and quickly deliver a large amount of gas to accelerate drying. As drying progresses, when the temperature and humidity approach the set values, the PLC controller 14 reduces the speed of the motor 2, reduces the air volume, avoids excessive energy consumption, and realizes on-demand air supply. In terms of airflow regulation, when it is necessary to adjust the airflow direction and intensity, the PLC controller 14 controls the second motor 306 to start. The second motor 306 drives the threaded rod 307 to rotate. Since the slider 308 is threadedly connected to the threaded rod 307 and slidably connected to the guide post 305, the rotation of the threaded rod 307 will drive the slider 308 to move along the guide post 305, thereby driving the rack 309 to move synchronously. The rack 309 meshes with the three sets of gears 304, thereby driving the shaft 302 to rotate. The guide plate 303 installed on the shaft 302 changes its angle accordingly, realizing the guidance and regulation of the airflow, so that the air field is evenly distributed and ensures that all parts of the PCB board are fully and evenly dried. In terms of convenient maintenance, when the filter element 12 needs to be replaced, pull the L-shaped sliding plate 403. The L-shaped sliding plate 403 overcomes the elastic force of the spring 405 and slides on the round rod 401, causing the clamping ring 404 to disengage from the limiting member 10. The filter element 12 can then be pulled out from the air intake pipe 9 for replacement. After replacement, release the L-shaped sliding plate 403, the spring 405 returns to its original position, and the clamping ring 404 re-engages on the limiting member 10, quickly completing the installation and fixation of the filter element 12. The whole process is simple and convenient to operate, improving maintenance efficiency.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
