Description

Flux cleaning unit

technical field

The utility model relates to a cleaning unit, in particular to a cleaning unit which utilizes high-pressure and high-temperature water jet flow to remove flux, and the cleaning liquid can be recycled and reused. the

Background technique

Flux is usually a mixture of rosin as the main component, which is an auxiliary material to ensure the smooth progress of the soldering process. Welding is the main process in electronic assembly. Flux is an auxiliary material used in welding. The main function of flux is to remove the oxides on the surface of the solder and the base material to be welded, so that the metal surface can reach the necessary cleanliness and prevent the surface from being welded during welding. The re-oxidation of the solder reduces the surface tension of the solder and improves the soldering performance. The performance of the flux directly affects the quality of electronic products. the

However, flux or oil stains will hinder the transmission of electronic component signals, so cleaning operations are often required to dissolve and remove the flux or oil stains. Soldering flux generally has two types: water-soluble flux and oil-soluble flux. The removal method of water-soluble flux is mostly directly washed with water, while oil-soluble flux is removed by washing with solvent. In addition, there is also a cleaning method that uses ultrasonic cleaning to remove flux or oil stains. Although it can effectively remove flux or oil stains, ultrasonic waves will damage electronic components and cause accelerated aging of electronic components. the

Utility model content

However, in the prior art, the effect of using the flushing method to remove the flux is not good, because it is difficult to effectively concentrate the water flow on the surface of the electronic component during flushing, and the force of the flushing water flow is insufficient, so it is difficult to remove the sticky flux from the electronic component , in order to achieve the purpose of removing the flux, it is necessary to repeatedly rinse, thus resulting in the doubling of the amount of water or solvents, thus increasing the manufacturing cost. Furthermore, the rinsed clear water cannot be recycled and reused because it has been mixed with flux or oil stains, but must be sent to the waste water treatment plant, which not only increases the manufacturing cost, but also wastes water resources. If it is not properly treated or leaked, it will will affect the natural environment. the

The main purpose of the present utility model is to provide a flux cleaning unit, including a cleaning device for spraying a cleaning liquid on an electronic component to remove a thing to be removed on the electronic component; a liquid collection tank, the The cleaning device is arranged in the collecting tank to receive the cleaning liquid mixed with the objects to be removed; a separating device is connected to the bottom of the collecting tank by a first pipeline to receive the liquid from the collecting tank. the discharge of the cleaning liquid mixed with the object to be removed, the object to be removed is naturally separated from the cleaning liquid, wherein the removal object is suspended above the cleaning liquid; a circulating liquid supply device, which receives the cleaning liquid from the separating device liquid, and return the cleaning solution to the cleaning device for reuse. the

The utility model is characterized in that the cleaning device can generate high-pressure and high-temperature water jet flow, and the high-pressure and high-temperature water jet flow can be directly sprayed on both sides of the electronic component. Therefore, when the cleaning device is cleaning, the high-pressure hot water jet flow It can effectively concentrate on the surface of electronic components, and the hot water flow of high-pressure washing is strong and powerful, so it can effectively remove sticky flux from both sides of electronic components without damaging the surface of electronic components , thereby improving the quality and yield of electronic products. the

Another feature of the present invention is that the collecting tank sends the object to be cleaned collected by the cleaning liquid together with the cleaning liquid to the separation device for separation treatment, and the circulating liquid supply device then separates the separated The cleaning solution is supplied to the cleaning device for cleaning treatment, so the cleaning solution can be recycled and reused, which greatly saves the amount of water or solvent used, greatly reduces the manufacturing cost, and avoids affecting the natural environment. the
