Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning technology, and in particular to a scraper cleaning device. Background Technology
[0002] In electronic product manufacturing, solder paste is typically used to solder electronic components. A squeegee and stencil are usually used to apply the solder paste to the PCB. Therefore, after processing, the squeegee needs to be cleaned to prevent moisture from the solder paste from evaporating and causing it to stick firmly to the squeegee. This can lead to problems with the solder paste on the PCB during subsequent product processing, such as the paste being too thin or too thick. Currently, the squeegee is cleaned manually using a spray gun or brush, which is inefficient. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a scraper cleaning device. By using several air cylinders installed on the air duct frame, air bubbles are sprayed out through the air ducts, causing the cleaning liquid to tumble, thereby achieving the effect of cleaning the scraper. The air cylinders provide air power to the air duct frame, causing the air duct frame to spray air bubbles into the cleaning liquid, making the cleaning liquid tumble, and thus cleaning the scraper. This eliminates the need for manual cleaning of each scraper using a spray gun, increasing the efficiency of scraper cleaning.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a scraper cleaning device, comprising:
[0005] A cleaning tank, which is rectangular in shape, has an opening at the top and a loading groove parallel to the horizontal plane on its side wall.
[0006] An air vent frame, having a plurality of air vents, is mounted on the loading trough.
[0007] An air cylinder, wherein the air cylinder is connected to an air passage.
[0008] In this technical solution, a cleaning tank is used to hold cleaning fluid, in which the scrapers are cleaned. The opening at the top of the cleaning tank is used to hold the cleaning fluid and the scrapers. The loading trough is used to place the scrapers and the air vent frame. The air vent frame is used to spray air bubbles, causing the cleaning fluid to tumble, thereby achieving the effect of cleaning the scrapers. The air cylinder is used to provide air power to the air vent frame, so that the air vent frame sprays air bubbles into the cleaning fluid, causing the cleaning fluid to tumble, and thus cleaning the scrapers. This eliminates the need for manual cleaning of each scraper using a spray gun, increasing the efficiency of scraper cleaning.
[0009] In some embodiments, the cleaning tank includes a loading end and an air outlet end, the loading end being disposed above the air outlet end, and the air vent frame being disposed at the air outlet end.
[0010] In this technical solution, the loading end is used to install the scraper, and the air outlet end is used to install the air tunnel frame.
[0011] In some embodiments, the cleaning tank further includes a sedimentation end, which is located below the air outlet end.
[0012] In this technical solution, the precipitating end is used to precipitate solder paste in the cleaning solution.
[0013] In some embodiments, the air tunnel frame is rectangular and includes a main beam and a crossbeam. The main beam extends along a first direction, and the crossbeam extends along a second direction. Both the main beam and the crossbeam are provided with hollow air channels. The crossbeam is fixed to the main beam, and the air channels of the main beam are connected to the air channels of the crossbeam. The air tunnel is disposed on the crossbeam.
[0014] In this technical solution, the main beam is used to install the crossbeam. The airflow is guided through the air passage in the main beam to the air passage in the crossbeam, and then discharged from the air hole on the crossbeam to achieve the effect of tumbling the cleaning fluid.
[0015] In some embodiments, the loading slot includes a first slot body, the air vent frame is disposed within the first slot body, and the first slot body is disposed at the air outlet end.
[0016] In this technical solution, the first groove is used to install the air tunnel frame.
[0017] In some embodiments, an air intake pipe is also included, which is connected to the main beam, and the air cylinder is connected to the air intake pipe.
[0018] In this technical solution, the inlet pipe is used to guide the air duct and the main beam.
[0019] In some embodiments, the scraper cleaning device further includes a scraper holder, and the loading tank further includes a second tank body parallel to the first tank body. The scraper holder is disposed in the cleaning tank through the second tank body, and the second tank body is disposed at the loading end.
[0020] In this technical solution, the scraper holder is used to install scrapers, thereby cleaning multiple scrapers simultaneously and improving the cleaning efficiency of the scrapers.
[0021] The beneficial effect of this utility model is that by using several air cylinders set on the air tunnel frame, the air tunnels spray out bubbles, causing the cleaning fluid to tumble, thereby achieving the effect of cleaning the scraper. The air cylinders provide wind power to the air tunnel frame, which causes the air tunnel frame to spray bubbles into the cleaning fluid, making the cleaning fluid tumble, and thus cleaning the scraper. There is no need to manually clean the scrapers one by one using spray gun equipment, which increases the efficiency of scraper cleaning. Attached Figure Description
