Description

Technical Field

[0001] This invention relates to the field of optoelectronic component technology, specifically to a circulating drying device for cleaning optoelectronic components. Background Technology

[0002] Optoelectronic components typically require precise cleaning during the production process, and the drying process after cleaning is crucial. To ensure rapid drying of the component surface and avoid secondary contamination, hot air circulation or infrared heating is usually used for drying.

[0003] Currently, the drying equipment for optoelectronic components on the market directly discharges heat after one use, and the heat energy cannot be effectively recovered, resulting in serious energy waste. The energy consumption of the drying process is high, especially when long-term continuous production is required. High energy consumption not only increases production costs, but also does not meet the current requirements for energy conservation and environmental protection. Therefore, there is an urgent need for a circulating drying device for cleaning optoelectronic components to solve the above-mentioned technical defects. Summary of the Invention

[0004] The purpose of this invention is to provide a circulating drying device for cleaning optoelectronic components, so as to solve the problem of high heat energy consumption in unidirectional airflow drying mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circulating drying device for cleaning optoelectronic components, comprising a drying chamber and a drive motor. Two sets of drive motors are fixedly connected to the rear end of the outer wall of the drying chamber. The output shaft of the drive motor is fixedly connected to a turntable on the inner wall of the drying chamber. A rotating seat is fixedly sleeved on the outer wall of the turntable. The rotating seat is movably assembled on the inner wall of the drying chamber. A drying rack is fixedly connected to the top of the rotating seat. Two sets of air outlets are provided on the right wall of the drying chamber. An air outlet duct is installed at each air outlet. A return air pipe is connected to the right side of the air outlet duct. An air inlet duct is installed to the left side of the return air pipe. A thermal radiation perforated plate is installed at the bottom end of the air inlet duct.

[0006] As a further technical solution of the present invention, the rotation range of the drying rack is 0-30° in the horizontal direction.

[0007] As a further technical solution of the present invention, a sliding groove is provided at the bottom right side of the drying rack, a sliding frame is sleeved on the outside of the sliding groove, a locking bolt is fixedly connected between the sliding frame and the sliding groove, and a baffle is fixedly connected to the top of the sliding frame.

[0008] As a further technical solution of the present invention, the drying rack is provided in two sets, and a spring rod is provided between the two sets of drying racks. The spring rod is hinged to a guide plate. The guide plate and the left side of the spring rod are respectively hinged to the left side of the inner wall of the drying chamber. The guide plate and the spring rod form a triangular structure. The width of the guide plate is greater than the width of the drying rack.

[0009] As a further technical solution of the present invention, an outlet is provided at the bottom of the drying chamber, and a slope is provided between the left side of the outlet and the inner wall of the drying chamber.

[0010] As a further technical solution of the present invention, an openable door is installed at the front end of the drying chamber, and a controller is provided on the right side of the outer wall of the drying chamber.

[0011] As a further technical solution of the present invention, two sets of dryers are provided on the left side wall of the drying chamber, a dust filter plate is installed on the left side of the dryer, a fan is installed inside the dryer, a heating wire is installed on the right side of the fan, and an air distribution plate fixed to the inner wall of the drying chamber is installed on the right side of the dryer.

[0012] As a further technical solution of the present invention, the side wall of the dust filter plate is hinged with a fastener, and a fastening groove is provided at the frame of the dryer, and the dust filter plate is fastened in the fastening groove by the fastener.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the circulating drying device for cleaning optoelectronic components not only realizes heat energy recovery and circulating drying, but also realizes gradual drying on drying racks at different levels, resulting in more thorough drying, and also makes the filter plate easy to disassemble; (1) By setting up a uniform air distribution plate, air outlet, air outlet duct, return air duct, air inlet duct, heat radiation perforated plate and drying rack, the uniform air distribution plate evenly directs the hot airflow to blow it onto the optoelectronic components placed on the drying rack. During the drying process, the hot and humid airflow is recovered at the air outlet and introduced into the return air duct through the air outlet duct, so that the airflow flows back to the air inlet duct and is then blown back onto the drying rack from the heat radiation perforated plate at the top. Through this circulating airflow design, only a lower temperature is needed to efficiently evaporate the moisture on the surface of the components. At the same time, some heat energy is recovered and utilized, reducing energy loss. Compared with the traditional unidirectional airflow drying method, the load on the heating system is reduced, making the drying more energy-efficient and efficient. (2) The device is equipped with a drying rack, baffle, dryer, drive motor, turntable, guide plate, ramp, and outlet. The optoelectronic components are arranged on the drying rack in sequence, with the right side in contact with the baffle. After the optoelectronic components on the first set of drying racks are heated by the dryer, the drive motor drives the turntable to rotate, causing the drying rack to tilt towards the dryer. This causes the optoelectronic components to roll onto the guide plate and fall into the next set of drying racks for secondary drying. After two rounds of heat exchange drying, the drying rack tilts again, causing the optoelectronic components to slide from the ramp into the outlet. The optoelectronic components are gradually dried on different levels of drying racks, reducing product defects caused by incomplete drying. (3) By setting up a dryer, a drying chamber, a dust filter plate, an air distribution plate, clips, and clip slots, the two sets of dryers of this device are installed side by side on the left side wall of the drying chamber. The external airflow is first treated by the dust filter plate, and then blown in evenly from the air distribution plate to ensure that the airflow entering the drying chamber is dust-free and clean. The dust filter plate is fixed to the clip slot by four sets of clips, so that it can be easily disassembled when it needs to be replaced, reducing the maintenance difficulty and ensuring the cleanliness of the optoelectronic components.

The rotating seat 10 is movably assembled on the inner wall of the drying chamber 1. A drying rack 19 is fixedly connected to the top of the rotating seat 10.

[0021] Specifically, such as Figure 1 and Figure 2 As shown, during the drying process, the hot and humid airflow is recovered at the air outlet 5 and introduced into the return air pipe 4 through the air outlet 6, so that the airflow flows back to the air inlet 3 and then blows back to the drying rack 19 from the top heat radiation perforated plate 2. Through this circulating airflow design, the moisture on the surface of the element can be evaporated efficiently with only a lower temperature, while some heat energy can be recovered and utilized, reducing energy loss.

[0022] The drying rack 19 has a rotation range of 0-30° in the horizontal direction. A sliding groove 9 is provided at the bottom right side of the drying rack 19. A sliding frame 8 is sleeved on the outside of the sliding groove 9. A locking bolt 20 is fixedly connected between the sliding frame 8 and the sliding groove 9. A baffle 7 is fixedly connected to the top of the sliding frame 8. The drying rack 19 is provided in two sets. A spring rod 23 is provided between the two sets of drying racks 19. A guide plate 22 is hinged to the spring rod 23. The guide plate 22 and the spring rod 23 are respectively hinged to the left side of the inner wall of the drying chamber 1. The guide plate 22 and the spring rod 23 form a triangular structure. The width of the guide plate 22 is greater than the width of the drying rack 19. An outlet 18 is provided at the bottom of the drying chamber 1. A ramp 17 is provided between the left side of the outlet 18 and the inner wall of the drying chamber 1.

[0023] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the optoelectronic components are arranged sequentially on the drying rack 19, with the right side in contact with the baffle 7. After the optoelectronic components on the first set of drying racks 19 undergo heat exchange with the dryer 12, the drive motor 21 drives the turntable 11 to rotate, causing the drying rack 19 to tilt towards the dryer 12, so that the optoelectronic components roll onto the guide plate 22 and fall into the next set of drying racks 19 for secondary drying. After two rounds of heat exchange and drying, the drying rack 19 tilts again, so that the optoelectronic components slide from the ramp 17 into the outlet 18.

[0024] The front end of the drying chamber 1 is equipped with an openable door. A controller is installed on the right side of the outer wall of the drying chamber 1. Two sets of dryers 12 are installed on the left side wall of the drying chamber 1. A dust filter plate 13 is installed on the left side of the dryer 12. A fan 14 is installed inside the dryer 12. A heating wire 15 is installed on the right side of the fan 14. An air distribution plate 16 is installed on the right side of the dryer 12 and fixed to the inner wall of the drying chamber 1.

[0025] Specifically, such as Figure 1 and Figure 4 As shown, the two sets of dryers 12 of this device are installed side by side on the left side wall of the drying chamber 1. The external airflow is first treated by the dust filter plate 13 for dust removal, and then blown in evenly from the air distribution plate 16 to ensure that the airflow entering the drying chamber 1 is dust-free and clean. The dust filter plate 13 is fixed to the groove 25 by four sets of fasteners 24 so that it can be easily disassembled when it needs to be replaced.

[0026] Working principle: The two sets of dryers 12 of this device are installed side by side on the left side wall of the drying chamber 1. The optoelectronic components are arranged sequentially on the drying rack 19, with the right side in contact with the baffle 7. After the optoelectronic components on the first set of drying racks 19 are heated by the dryer 12, the drive motor 21 drives the turntable 11 to rotate, causing the drying rack 19 to tilt towards the dryer 12. The optoelectronic components then roll onto the guide plate 22 and fall into the next set of drying racks 19 for secondary drying. After two rounds of heat exchange drying, the drying rack 19 tilts again, allowing the optoelectronic components to slide from the ramp 17 into the outlet 18. The optoelectronic components are gradually dried on the drying racks 19 at different levels. During the drying process, the hot and humid airflow is recovered at the air outlet 5 and introduced into the return air pipe 4 through the air outlet 6, so that the airflow flows back to the air inlet 3 and is then blown back onto the drying rack 19 from the top heat radiation perforated plate 2. Through this circulating airflow design, the moisture on the surface of the components can be evaporated efficiently at a relatively low temperature, while some heat energy can be recovered and utilized.
