Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial cleaning technology, and in particular to a fully automatic cleaning system. Background Technology
[0002] Before leaving the factory, electronic products need to have their components and casings cleaned to ensure they are spotless. Current technology typically involves multiple chemical cleaning processes, followed by a final rinse with water and drying before shipment. Many of these processes require manual operation, which poses risks of accidents and can lead to inconsistent cleaning results due to varying levels of worker skill and experience. Therefore, a system that avoids multiple chemical cleaning steps while increasing automation is needed to effectively mitigate these problems. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fully automatic cleaning system that is simple in structure, harmless and highly automated.
[0004] The technical solution adopted by this utility model is as follows: This utility model includes a back-end center and a feeding mechanism, an automated cleaning line, a product surface detection device, and a discharging mechanism connected in sequence. The back-end center is electrically connected to the feeding mechanism, the automated cleaning line, the product surface detection device, and the discharging mechanism. An external power supply provides power to the entire fully automated cleaning system. The automated cleaning line includes a main body with a production line on it. Above the production line, a first water spraying device, a first air spraying device, a second water spraying device, a brush cleaning device, a third water spraying device, a second air spraying device, and a drying device are arranged in sequence, facing downwards towards the production line. Inside the main body, a micro-nano bubble water generating device is arranged. The micro-nano bubble water generating device supplies micro-nano bubble water to the first water spraying device, the second water spraying device, and the third water spraying device, respectively. The micro-nano bubble water cleans the products located on the production line at room temperature.
[0005] As can be seen from the above scheme, through the cooperation of the back-end center and the sequentially connected feeding mechanism, automated cleaning line, product surface inspection device, and unloading mechanism, the back-end center realizes the automated coordination of the feeding mechanism, automated cleaning line, product surface inspection device, and unloading mechanism, ensuring the automated operation of the entire system. Secondly, the first, second, and third water spray devices are connected to the micro-nano bubble water generating device, and the micro-nano bubble water provided by the micro-nano bubble water generating device cleans the products on the production line at room temperature. Here, after detection, each micro-nano bubble has an electric charge on its surface. The surface charge of the micro-nano bubble continuously concentrates as the bubble shrinks. When the micro-nano bubble shrinks and disappears in the water, the stored pressure and charge potential are released, and its energy generates strong oxidizing activity. This invention utilizes hydroxyl radicals, a strong oxidizing agent, to oxidize and remove oil stains and dirt from the product surface. A jet cleaning device then physically removes dust from the product surface. A brush cleaning device directly acts on the product surface to physically remove dirt. Finally, a drying device dries the cleaned product, ensuring it is ready for subsequent packaging processes. Compared to existing technologies, this invention eliminates the need for chemicals, preventing secondary pollution or damage to the product and achieving harmless, environmentally friendly cleaning. Furthermore, the cleaning line's workflow is simple, eliminating the need for repeated cleaning, thus reducing costs and shortening the process, achieving cost reduction and efficiency improvement. Additionally, the system's simple structure and easy assembly effectively reduce system costs and improve efficiency.
[0006] Furthermore, a qualified product output line and a non-compliant product output line are also provided on the rear side of the unloading mechanism. The non-compliant product output line is connected to the loading mechanism via a return line. Thus, by setting up qualified and non-compliant product output lines, qualified products are directly output to the next process via the qualified product output line; while non-compliant products flow out via the non-compliant product output line and return to the loading mechanism via the return line for re-cleaning. This ensures the cleanliness of the non-compliant products, achieves automated operation, and improves efficiency.
[0007] Furthermore, the production line is a roller-type production line, divided into several product transport channels. Each product transport channel transports and cleans products separately. The first water spray device, the first air spray device, the second water spray device, the brush cleaning device, the third water spray device, and the second air spray device are respectively equipped with a first water spray head, a first air spray head, a second water spray head, a brush, a third water spray head, and a second air spray head on each product transport channel. The first water spray device, the second water spray device, and the third water spray device all include a water collection pipe located above the production line. The first air spray device and the second air spray device also include an air collection pipe. Therefore, by configuring the production line into several product transport channels, each product transport channel can perform product cleaning separately, thereby achieving highly efficient cleaning. This greatly improves cleaning efficiency. The corresponding water spray head and air spray head are also positioned on each product transport channel to ensure the best cleaning effect for the products in each channel.
[0008] Furthermore, both the first and second jetting devices emit nitrogen gas, and the drying device is a drying oven. Therefore, the use of nitrogen gas prevents secondary oxidation of the product surface, avoiding secondary damage. The drying device itself is simple in structure, easy to implement, and convenient to operate.
[0009] Furthermore, the micro / nano bubble water generating device produces micro / nano bubble water by introducing ozone, oxygen, or nitrogen into ultrapure water. The bubble diameter in the micro / nano bubble water ranges from 100 nm to 50 μm. Therefore, the bubble diameter of micro / nano bubbles ranges from 100 nm to 50 μm. Micro / nano bubbles are between micron-sized bubbles and nano-sized bubbles, possessing physical and chemical properties not found in conventional bubbles, thus ensuring the cleaning performance of this invention.
[0010] Furthermore, the micro / nano bubble water generating device includes a dissolving tank, a pure water tank, a transfer pump, a spray pipe disposed in the dissolving tank, an outlet pipe connected to the dissolving tank, a pressure relief valve, and a gas generating device. The pure water tank and the gas generating device respectively send pure water and gas out, which then pass through the transfer pump and enter the spray pipe located in the dissolving tank. The spray pipe sprays the water-gas mixture into the dissolving tank. The outlet pipe transports the water-gas mixture in the dissolving tank to the first water spraying device, the second water spraying device, and the third water spraying device. The pressure relief valve is disposed at the upper part of the dissolving tank. A liquid level gauge is disposed in the dissolving tank, and the liquid level gauge is connected to the pressure relief valve. Therefore, the micro-nano bubble water generating device uses a transfer pump to mix the introduced gas with ultrapure water, and then sends the mixture into a spray pipe. The spray pipe sprays the water-gas mixture into the dissolving tank, so that the water in the dissolving tank becomes micro-nano bubble water. Finally, the micro-nano bubble water is sent to the first water spray device, the second water spray device, and the third water spray device to clean the product. It has a simple structure and low cost.
[0011] Furthermore, the gas generating device is an ozone generator, a nitrogen generator, or an oxygen tank. Therefore, depending on the actual situation, different gases can be selected to be introduced into the ultrapure water to achieve the cleaning of different products, making this invention widely adaptable.
[0012] Furthermore, the transfer pump is a diaphragm pump. Here, the diaphragm of the diaphragm pump is formed of fluoropolymer, thereby effectively preventing the cleaning water from being contaminated by metal.
[0013] Finally, both the loading and unloading mechanisms are multi-vacuum suction cup robotic arms driven by a robotic arm for picking up and placing materials. The product surface inspection device is a CCD inspection camera. The product surface inspection device performs surface inspection on the cleaned products and transmits the inspection results back to the back-end center. It is evident that the loading and unloading mechanisms utilize multi-vacuum suction cup robotic arms. Leveraging the flexibility of the robotic arms, the multi-channel requirements of automated cleaning lines are well met, allowing one robotic arm to operate on multiple channels, thus reducing the complexity of the equipment. Furthermore, the product surface inspection device uses a CCD inspection camera. Utilizing the high definition of the camera, defects on the product surface can be detected as accurately as possible, improving efficiency and inspection accuracy while reducing the labor intensity of the workers.

Here, the control device sets the operating speed of the production line 7, the spraying time of the first water spray device 8, the second water spray device 10, and the third water spray device 12, the jetting pressure and jetting time of the first jet device 9 and the second jet device 13, the working time of the micro-nano bubble water generator and the gas generator, and collects the readings from the liquid level gauge.
