Tin paste agitator for production of LED (light-emitting diode) circuit boards and agitation method

Abstract

The invention discloses a tin paste agitator for the production of LED (light-emitting diode) circuit boards in the technical field of LEDs. Pillars are mounted on the left side and the right side ofthe top of a base plate, wherein supporting bearings sleeve the outer ends of supporting shafts, moreover, the two sets of supporting shafts are symmetrically arranged on the outer wall of a base, anagitating tank is arranged in an inner cavity of the base, a top sealing cover is arranged on the top of the agitating tank through hinges, a feed pipe and an agitating motor are respectively arrangedon the left side and the center of the top of the agitating tank, furthermore, both the feed pipe and the agitating motor are arranged in an inner cavity of the top sealing cover, and an agitating shaft is connected to the bottom power end of the agitating motor through a coupling. The sealing performance of the tin paste agitator is good; by arranging the top sealing cover, the feeding pipe andthe agitating motor having the possibility of air leakage are wrapped in a sealed space in the process of agitation, consequently, a good sealed environment is provided for the agitating tank, and tinpaste is prevented from being in contact with the air to cause the phenomenon of tin paste oxidation and affecting the quality of the tin paste in use.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a solder paste mixer and a mixing method for producing LED circuit boards. Background technique [0002] LED circuit board is the abbreviation of printed circuit board. Both LED aluminum substrate and FR-4 fiberglass circuit board belong to PCB. To say the difference, just compare LED aluminum substrate and FR-4 fiberglass circuit board. The circuit is printed on the aluminum material with better thermal conductivity, and then the electronic components are soldered on it. When processing the LED circuit board, it is necessary to use a very important and indispensable raw material, which is solder paste. The solder paste itself is composed of tiny Composed of metal alloy and flux, the solder paste needs to be stored in a lower temperature environment during long-term transportation, and the metal alloy particles are easy to sink into the bottom of the paste. It is used in the process...

AI Technical Summary

Problems solved by technology

[0003] There are two existing solder paste stirring methods, manual stirring and its stirring. Manual stirring often causes uneven stirring, which affects the processing of LED circuit boards. For machine stirring, there is also uneven stirring. Moreover, the solder paste cannot be exposed to the air, and it is easy to oxidize and deteriorate the solder paste in contact with the air. Therefore, we propose a solder paste mixer and mixing method for LED circuit board production
