Quantitative adding auxiliary device for scraper solder paste cleaning agent

Abstract

The invention relates to the technical field of computer mainboard scraper cleaning, and discloses a quantitative adding auxiliary device for a scraper solder paste cleaning agent. The quantitative adding auxiliary device comprises a lifting screw rod, wherein the left side of the lifting screw rod is movably connected with a rotating gear; the left side of the rotating gear is movably connected with a lifting toothed plate; the left side of the lifting toothed plate is fixedly connected with an extrusion plate; the top of the extrusion plate is movably connected with a liquid storage barrel;and the lifting screw rod and a lifting block are driven to descend by compressing a reset spring. In the descending process of the lifting screw rod, the rotating gear is driven to rotate clockwise,the rotating gear rotates clockwise to drive the lifting toothed plate to ascend, the lifting toothed plate ascends to drive the extrusion plate to ascend, then the internal space of the liquid storage barrel is compressed, and the cleaning agent in the liquid storage barrel flows into a to-be-sprayed area through the top of an extension spring, so that the cleaning agent in the liquid storage barrel is quantitatively discharged, and the effect of automatically spraying an appropriate amount of cleaning agent according to the weight of solder paste is achieved.

Description

technical field [0001] The invention relates to the technical field of computer motherboard scraper cleaning, in particular to an auxiliary device for quantitatively adding a scraper solder paste cleaning agent. Background technique [0002] With the development of science and technology, computers have become an indispensable tool in people's daily life. The motherboard of a computer is one of the most important components of computing. It needs to print solder paste on its surface with a scraper and a stencil during production. In order to facilitate the installation of subsequent electronic components, but after printing the solder paste on the scraper, there is often some solder paste on the surface, which will affect the use of the next printing, so the scraper needs to be cleaned regularly. [0003] At present, there are two ways to clean the scraper: manual cleaning and automatic cleaning. However, due to the difference in the residual solder paste on different scrape...
