Description

Technical Field

[0001] The present application relates to the technical field of safe cleaning, and in particular to an isopropyl alcohol cleaning device. Background Art

[0002] Printed circuit boards (PCBs) are core components of electronic devices, used to provide electrical connections and support electronic components. As the complexity and integration of electronic devices continue to increase, the manufacturing process of PCBs has become more sophisticated and complex. During the PCB production process, various dirt and residues such as solder residues, flux and other contaminants are usually left behind during the welding and assembly stages. If these dirt are not thoroughly removed, they will affect the performance and reliability of the circuit board. Therefore, thorough cleaning of PCBs has become an indispensable step in the production process.

[0003] Currently, using isopropyl alcohol for PCB cleaning is an effective method because it can efficiently dissolve and remove contaminants on the surface of PCBs. However, isopropyl alcohol is a volatile chemical and there are certain safety risks during its use, including potential fire hazards and impacts on the health of operators. Although isopropyl alcohol has a significant cleaning effect, its safety hazards cannot be ignored. On the other hand, not using isopropyl alcohol as a cleaning agent may result in poor cleaning effects on PCBs, making it difficult to completely remove contaminants, affecting the quality and reliability of the circuit board. Therefore, how to improve the cleaning effect of PCB boards while ensuring safety as much as possible is a current problem. Utility Model Content

[0004] In order to improve the cleaning effect of PCB boards while ensuring safety as much as possible, the present application provides an isopropyl alcohol cleaning device. The present application provides the following technical solutions:

[0005] An isopropyl alcohol cleaning device comprises a cleaning box and a cleaning tool arranged on one side of the cleaning box, a side of the cleaning box close to the cleaning tool is provided with a clearance groove for the cleaning tool to enter, and the cleaning tool is connected to a driving mechanism for driving it to enter the cleaning box;

[0006] A pipe joint is provided in the cleaning box, and the pipe joint is connected to a bent first bamboo tube and a second bamboo tube. The end of the first bamboo tube away from the pipe joint is connected to a cleaning liquid nozzle, and the end of the second bamboo tube away from the pipe joint is connected to a gas nozzle; the pipe joint is also connected to a cleaning liquid barrel through a pipe, and a through hole is opened at the bottom of the cleaning box and is connected to a waste liquid barrel through a pipe.

[0007] In a specific feasible implementation, the cleaning tooling includes a fixing frame, a cleaning tray, and a closing plate. The fixing frame is arranged on the driving mechanism. The closing plate is installed on one side of the fixing frame close to the cleaning tank. The cleaning tray is connected to one side of the closing plate close to the cleaning tank. The cleaning tray is horizontally arranged, and a groove for placing the PCB is formed on the top surface of the cleaning tray.

[0008] In a specific feasible implementation, the closing plate has the same size as the relief groove formed on the cleaning tank for the cleaning tooling to enter.

[0009] In a specific feasible implementation, a cylinder is arranged on one side of the cleaning tank away from the cleaning tooling. The piston rod of the cylinder passes through the side wall of the cleaning tank and is connected to the pipeline joint.

[0010] In a specific feasible implementation, the gas nozzles are fan-shaped nozzles and there are two of them. The two gas nozzles are respectively located above and below the cleaning tooling.

[0011] In a specific feasible implementation, an isopropyl alcohol detector for detecting the concentration of isopropyl alcohol is arranged on the outer wall of the cleaning tank.

[0012] In a specific feasible implementation, an air duct is connected to the outer wall of the cleaning tank. The air duct is used to cooperate with an air suction fan used in the isopropyl alcohol cleaning device. One end of the air duct away from the cleaning tank is connected to the air suction fan.

[0013] In a specific feasible implementation, a capacitive proximity sensor is arranged on the outer wall of the waste liquid bucket.

[0014] In summary, the beneficial effects of the present application at least include:

[0015] 1) The design of the cleaning tray can make the cleaning of the PCB board more stable, and to a certain extent, prevent the PCB board from shifting or being washed away due to the jet force during the cleaning process. Compared with the traditional clamping device, the cleaning tray can better fix the PCB board and ensure the uniformity and effect of cleaning.

[0016] 2) The design of the fan-shaped nozzles can ensure that the air flow diffuses in a fan shape and covers a larger area. One nozzle is arranged above and one below respectively, which can realize the all-round drying of the PCB board and ensure that all surfaces of the PCB board, including the top and bottom, can be evenly cleaned.

[0017] By placing the PCB board on the cleaning tray and starting the sliding table cylinder to drive the cleaning tray into the cleaning box, at this time, start the cylinder to drive the cleaning liquid nozzle to reciprocate and spray atomized isopropyl alcohol for cleaning. After cleaning, perform a drying operation through multiple gas nozzles. After drying, start the sliding table cylinder again to drive the cleaning tray to reset. During the cleaning process, the cleaning box forms an almost airtight space through the closing plate, and at the same time, the volatilized isopropyl alcohol is absorbed and discharged by the suction fan, so as to improve the cleaning effect of the PCB board while ensuring safety as much as possible.

[0027] An embodiment of this application discloses an isopropyl alcohol cleaning device.

[0028] Referring to Figure 1 , the isopropyl alcohol cleaning device includes a slide table cylinder 3 and a closed cleaning tank 1. The slide table cylinder 3 is fixedly installed on one side of the cleaning tank 1. A cleaning tooling 2 is provided on the slide table cylinder 3. Combining Figure 2 , the cleaning tooling 2 includes a fixing frame 24, a cleaning tray 21 and a closing plate 22. The fixing frame 24 is fixedly installed on the slide of the slide table cylinder 3. The closing plate 22 is fixedly installed on the side of the fixing frame 24 close to the cleaning tank 1. The cleaning tray 21 is installed on the side of the closing plate 22 close to the cleaning tank 1. The cleaning tray 21 is horizontally arranged, and a groove 23 for placing a PCB board is provided on the top surface of the cleaning tray 21. The design of the cleaning tray 21 enables the PCB board to be cleaned more stably, and to a certain extent prevents the PCB board from being displaced or washed away due to the spraying force during the cleaning process. Compared with the traditional clamping device, the cleaning tray 21 can better fix the PCB board and ensure the uniformity and effect of cleaning.

[0029] Referring to Figure 1 and Figure 2, on one side of the cleaning tank 1 close to the cleaning tooling 2, a relief groove for the cleaning tray 21 to enter is provided, and the size of the closing plate 22 is the same as that of the relief groove provided on the cleaning tank 1 for the cleaning tray 21 to enter. The same size of the relief groove and the closing plate 22 can ensure that the cleaning tank 1 can be completely sealed during the cleaning process. This helps to prevent the volatilization and leakage of isopropyl alcohol, reduce the emission of harmful gases, and improve the safety during the cleaning process. At the same time, the same size of the closing plate 22 and the relief groove can ensure that the cleaning tray 21 is stable and does not shake when entering the cleaning tank 1, avoiding displacement or vibration caused by the device gap, thereby improving the stability and accuracy of the operation. In addition, through the sealing design, it can effectively prevent the waste liquid and waste gas generated during the cleaning process from diffusing into the external environment, keep the working area clean and safe, and reduce the health impact on the operators. In implementation, after placing the PCB board on the cleaning tray 21, start the sliding table cylinder 3 to drive the cleaning tray 21 into the cleaning tank 1. At this time, the closing plate 22 can seal the cleaning tank 1, and then the isopropyl alcohol cleaning operation is carried out.

[0030] Refer to Figure 1 , a pipeline joint 6 is provided in the cleaning tank 1. Combining Figure 2 , the pipeline joint 6 is connected with a bent first corrugated pipe 7 and a second corrugated pipe 8. It should be noted that since the drawing cannot show the bending effect of the corrugated pipe, the corrugated pipe is in a straight state in the drawing. In reality, the corrugated pipe is in a bent state and is arranged in the cleaning tank 1. One end of the first corrugated pipe 7 far from the pipeline joint 6 is connected with a cleaning liquid nozzle 71, and one end of the second corrugated pipe 8 far from the pipeline joint 6 is connected with a gas nozzle 81. Combining Figure 3 , the first corrugated pipe 7 is connected with a cleaning liquid barrel 11 filled with isopropyl alcohol through the pipeline joint 6 and a pipeline, and the pipeline is not shown. A through hole is provided at the bottom of the cleaning tank 1 and is connected with a waste liquid barrel 12 through a pipeline. A capacitive proximity sensor is provided on the outer wall of the waste liquid barrel 12. The setting of the capacitive proximity sensor does not require direct contact with the measured object, which can avoid the contact between the sensor and the isopropyl alcohol waste liquid, reduce wear and corrosion, and thus improve the service life and reliability of the sensor. At the same time, the capacitive proximity sensor can monitor the liquid level in real time, helping the operator to timely understand the state of the waste liquid barrel 12 and avoid poor cleaning effects caused by waste liquid overflow or too low liquid level.

[0031] Refer to Figure 1 and Figure 2, on the side of the cleaning tank 1 away from the cleaning tooling 2, a cylinder 5 is fixedly installed. The piston rod of the cylinder 5 passes through the side wall of the cleaning tank 1 and is connected to the pipeline joint 6. In implementation, after the cleaning tray 21 enters the cleaning tank 1, first, atomized isopropanol is sprayed through the cleaning liquid nozzle 71 for cleaning operation. At the same time, the cylinder 5 is started, so that the piston rod can drive the cleaning liquid nozzle 71 connected to the pipeline joint 6 to reciprocate, thereby improving the cleaning effect of the PCB board. After isopropanol cleaning, gas is sprayed through the gas nozzle 81 for drying operation. The gas nozzle 81 is a fan-shaped nozzle and there are two of them. Correspondingly, there are also two second bamboo tubes 8. When the cleaning tray 21 enters the cleaning tank 1, the two gas nozzles 81 are respectively located above and below the cleaning tray 21. The design of the fan-shaped nozzle can ensure that the air flow diffuses in a fan shape, covering a larger area. One nozzle is provided above and one below respectively, which can realize the all-round drying of the PCB board, ensuring that all surfaces of the PCB board, including the top and bottom, can be evenly cleaned. In addition, the first bamboo tube 7 and the corresponding cleaning liquid nozzles 71 can also be set to several, and the cleaning effect can be improved by adding the cleaning liquid nozzles 71. In implementation, after cleaning and drying, the sliding table cylinder 3 is started again to drive the cleaning tooling 2 to reset.

[0032] Refer to Figure 1 , an isopropanol detector 9 for detecting the concentration of isopropanol is provided on the outer wall of the cleaning tank 1. The isopropanol detector 9 can monitor the concentration of isopropanol in the cleaning tank 1 in real time, ensuring that an appropriate concentration of isopropanol is always maintained during the cleaning process to ensure the stability and consistency of the cleaning effect. An air duct 4 is connected to the outer wall of the cleaning tank 1. The air duct 4 is used to cooperate with the suction fan used in the isopropanol cleaning device. One end of the air duct 4 away from the cleaning tank 1 is connected to the suction fan. Isopropanol is a volatile chemical, and its vapor is flammable and toxic. Through the air duct 4 and the suction fan, the isopropanol vapor generated during the cleaning process can be effectively removed, reducing the risks of explosion and poisoning and ensuring the safety of the operating environment. In addition, the isopropanol vapor generated during the cleaning process will affect the air quality of the working environment. The air duct 4 and the suction fan can timely remove these harmful gases, improve the air quality of the working environment, and provide a healthier working condition.

[0033] To sum up, by placing the PCB board on the cleaning tray 21, starting the sliding table cylinder 3 to drive the cleaning tray 21 into the cleaning tank 1, at this time, starting the cylinder 5 to drive the cleaning liquid nozzle 71 to reciprocate and spray atomized isopropanol for cleaning, after cleaning, drying is carried out through multiple gas nozzles 81, and after drying, starting the sliding table cylinder 3 again to drive the cleaning tray 21 to reset. During the cleaning process, through the closing plate 22, the cleaning tank 1 forms an almost airtight space, and at the same time, the volatilized isopropanol is absorbed and discharged through the suction fan, so as to improve the cleaning effect of the PCB board while ensuring safety as much as possible.

[0034] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
