Description

Technical Field

[0001] This application relates to the field of electronic manufacturing, and more particularly to an automatic air-wash cleaning device for printed circuit boards. Background Technology

[0002] With the rapid development of electronic products, the demand for printed circuit boards (PCBs) has increased dramatically. Furthermore, people are demanding higher pixel counts for camera modules, and environmental requirements are becoming increasingly stringent. Cleaning PCBs removes flux around components and removes flowing foreign matter, resulting in higher color resolution and more vibrant images when the camera module is assembled. To ensure product quality and reduce water pollution, PCBs require cleaning, multiple rinsing, and drying processes.

[0003] Existing cleaning equipment cannot minimize cleaning fluid residue on printed circuit boards during use, and it easily contaminates the second, third, and fourth pure water tanks, leading to unstable product quality. Furthermore, existing equipment often uses compressed air knives during air spraying, but compressed air can easily retain substances such as oil and water, which can further contaminate the cleaning fluid, resulting in a decrease in the cleaning power of the cleaning fluid. In addition, the equipment does not pay enough attention to environmental protection issues during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic air-blowing cleaning device for printed circuit boards, which overcomes the deficiencies of existing technologies. The aim is to solve the problems of existing cleaning devices, which fail to minimize cleaning fluid residue on printed circuit boards and easily contaminate the second, third, and fourth pure water tanks, leading to unstable product quality. Furthermore, existing equipment often uses compressed air knives during air-blowing, but compressed air can easily retain oil, water, and other substances, further contaminating the cleaning fluid and reducing its cleaning power. Additionally, the equipment does not adequately address environmental protection issues during operation.

[0005] To achieve the above objectives, this application provides the following technical solution: A blower is included, with a fixed frame on one side, a cleaning frame at the bottom of the fixed frame, two sets of suspension frames installed on the upper side of the fixed frame, suspension rods at the bottom of both sets of suspension frames, and a cleaning frame cover at the other end of each suspension rod.

[0014] By adopting the above technical solution and setting up a placement frame, the placement frame can be quickly and easily removed from the top of the lifting frame after the air spraying is completed, and the hollow design allows the cleaning liquid to fall to the bottom better.

[0015] As a preferred technical solution of this application, the inside of the box door is provided with an observation window, the observation window is made of transparent glass, and the outside of the box door is equipped with a handle.

[0016] By adopting the above technical solution and providing an observation window, the interior of the air blower can be easily observed during use, and the handle can be easily opened and closed.

[0017] As a preferred technical solution of this application, the bottom of the air shower is provided with four sets of universal wheels, and the four sets of universal wheels are located at the four corners of the bottom of the air shower.

[0018] By adopting the above technical solution, the four sets of universal wheels can make the transfer device more convenient and labor-saving, thus improving its practicality.

[0021] The beneficial effects of this application are:

[0022] 1. By setting up a cleaning tank, the printed circuit board can be placed directly inside the cleaning frame during use. Then, multiple sets of air blades inside the cleaning frame cover blow the circuit board below. The air vents are located at the bottom of the cleaning frame cover, which can blow the cleaning liquid dripping from the cleaning frame cover downwards at a uniform speed. This setting can save on solution costs. Moreover, under the blowing of the air blades, the greater the weight of the external cleaning liquid dripping inside the cleaning frame from the printed circuit board, the less contamination will be on the subsequent pure water tanks. This is beneficial to improving rinsing power and reducing the subsequent cleaning burden. The device uses an air pump to deliver high-pressure gas as the air source for the air blades. The blown air is relatively clean and free of impurities, further reducing contamination of the cleaning solution.

Air-blowing knives 3 are installed inside the multiple mounting slots 205. Air vents 30 are provided at the bottom of the air-blowing knives 3. 1. A mounting port 302 is provided on one side of the air shower knife 3. Two sets of quick-connect air nozzles 303 are provided on the top of the air shower knife 3. An air pipe 304 is installed at one end of each set of quick-connect air nozzles 303. An air pump 4 is installed on the top of the air shower machine 1. A connecting pipe 401 is provided at the output end of the air pump 4. The other end of the connecting pipe 401 is fixedly connected to the air pipe 304. A lifting mechanism 206 is provided inside each of the two sets of fixing frames 2. A lifting frame 207 is provided on one side of the lifting mechanism 206. A placement frame 208 is provided above the lifting frame 207. A control panel 5 is installed on the top of the air shower machine 1. The control panel 5 is electrically connected to the air pump 4.

[0031] By setting up a blower, during use, the lifting mechanism 206 first raises and lowers the lifting frame 207 on one side, allowing multiple circuit boards inside the placement frame 208 to be cleaned inside the cleaning frame 201. After cleaning, it is raised above the cleaning frame 201, and multiple sets of blower blades inside the cleaning frame cover blow the circuit boards below. The air vents are located at the bottom of the cleaning frame cover, which blows the cleaning liquid dripping downwards at a uniform speed. This setup saves on solution costs. Furthermore, the greater the weight of the external cleaning liquid dripping from the printed circuit boards inside the cleaning frame under the blower blades, the less contamination is caused to the subsequent pure water tanks, improving rinsing power and reducing the burden on subsequent cleaning processes. The device uses an air pump 4 to deliver high-pressure gas as the air source for the blower blades 3, resulting in a cleaner airflow without impurities, further reducing contamination of the cleaning liquid. The control panel 5 allows for convenient external control by supervisors, enhancing the device's practicality.

[0032] Reference Figure 1A collection pipe 6 is installed at the bottom of the cleaning frame 201. One side of the collection pipe 6 is connected to the interior of the cleaning frame 201. A filter screen is installed inside the collection pipe 6, and a collection cover 601 is installed at the top of the collection pipe 6. A door 7 is installed on the front of the air shower 1.

By rotating the screw 901 during use, the stop plate 902 can be brought into contact with the ground, thus securing the device and improving its practicality.

[0034] Working Principle: By setting up the cleaning tank 1, the printed circuit board can be placed directly inside the cleaning frame 201. Then, multiple sets of air spray knives 3 inside the cleaning frame cover 204 above blow the circuit board below. The air vents 301 are located at the bottom of the cleaning frame cover 204, which can blow the cleaning solution dripping downwards from the cleaning frame cover 204 downwards at a uniform speed. This setting can save on solution costs. Moreover, under the blowing of the air spray knives 3, the greater the weight of the external cleaning solution dripping inside the cleaning frame 201, the less contamination will be on the subsequent multiple pure water tanks, which is beneficial to improving rinsing efficiency. The washing power reduces the burden of subsequent cleaning. The device uses an air pump 4 to deliver high-pressure gas as the air source for the air shower knife 3. The blown air is relatively clean and free of impurities, further reducing the contamination of the cleaning fluid. By setting up a collection pipe 6, the cleaning fluid dripping after the printed circuit board is blown by the air shower knife 3 can enter the interior of multiple outflow holes 206 through the tilt of the bottom of the cleaning frame 201 and be collected by the collection pipe 6. It then enters the collection tank 602 for better collection, which facilitates subsequent purification and treatment. It can also prevent the cleaning fluid from accumulating inside the cleaning frame 201 and improve the cleaning efficiency.

[0035] Among them, by setting up the control panel 5, the supervisor can easily control the device from the outside during use, which improves the practicality of the device. By setting up the box door 7, the inside of the blower 1 can be sealed more easily during use, which also improves the practicality of the device.

[0036] Meanwhile, by setting up the placement frame 208, after the blowing is completed, the placement frame 208 can be quickly and easily removed from the top of the lifting frame 207, and the hollow design allows the cleaning liquid to fall to the bottom better.

[0037] In addition, the observation window 702 allows for convenient observation of the interior of the air shower 1 during use, and the handle 703 allows for easy opening and closing of the box door 7. The four sets of casters 8 make it easier and less strenuous to transfer the device, improving its practicality. The fixing plate 9 allows the device to be fixed by rotating the screw 901 to make the plate 902 abut against the ground, thus improving its practicality.
