Assembly process for magnetic cores and substrates of surface mounting type power inductors

Abstract

The invention discloses an assembly process for magnetic cores and substrates of surface mounting type power inductors. The assembly process comprises the steps of filling the bottom of a container with auxiliary rods; pouring magnetic cores into the container; shaking the container to enable the magnetic cores to be arranged in grooves of the auxiliary rods; withdrawing the remaining magnetic cores; filling the magnetic cores in the empty cavities; rearranging the magnetic cores that are not arranged well; opening glue grooves of spreaders, and placing in and fixing the auxiliary rods; withdrawing and rearranging the whole auxiliary rods if the magnetic cores are inclined; shifting the glue to front ends of spreading blocks, and fixing the spreading blocks; spreading glue; arranging the auxiliary rods horizontally; pasting substrates; placing the auxiliary rods into grooves of pressing rod clamps; aligning and overlapping upper pressing rods with the auxiliary rods; placing the rods back into the grooves of the pressing rod clamps after the rods change positions up and down; taking up the auxiliary rods; performing visual inspection on the magnetic cores; and placing the upper pressing rods qualified through the visual inspection into a tunnel kiln for drying. Compared with the prior art, the assembly process for magnetic cores and substrates of surface mounting type power inductors solves problems of poor pasting quality and low production efficiency of prior manual magnetic core pasting on substrates.

Description

technical field [0001] The invention relates to the technical field of manufacturing electronic components, in particular to a method for manufacturing a chip-type power inductor. Background technique [0002] Among the SMD power inductors manufactured by our company, one of the inductor skeletons is composed of an "I"-shaped magnetic core and a negative film pasted on the magnetic core. The assembly of the magnetic core and the negative film mentioned above is all manually completed one by one by the operator. The operator first smears glue on the top of a magnetic core by hand, and then pastes a negative film on the glue surface of the magnetic core. Although this method is very simple, only relying on the operator to use his hands cannot ensure that the magnetic core is just pasted on the center of the negative, and there are often sticking deviations and crooked phenomena, which will cause certain damage to the electrical parameters of the finished product. The impact ...

Although this method is very simple, only relying on the operator to use his hands cannot ensure that the magnetic core is just pasted on the center of the negative, and there are often sticking deviations and crooked phenomena, which will cause certain damage to the electrical parameters of the finished product. The impact of this completely manual production method cannot guarantee the quality of product assembly, and the company will also cause a large number of defective and waste products
