Combined jig for improving manufacturing efficiency of small-sized transformer and method thereof

Abstract

The invention discloses a combined jig for improving a manufacturing efficiency of a small-sized transformer. The combined jig comprises a sliding trough plate, a glue dispensing strip, and a varnish containing and immerging strip, wherein multiple sliding ways are formed in the front side of the sliding trough plate; two trough positions are formed in each sliding way; one trough position is a wide trough used for bearing two rows of pins of the transformer while the other trough position is a narrow trough used for bearing a magnetic core surface at the top part of the transformer; a trough position used for adsorbing the magnetic core at the top part of the transformer is formed in the front side of the glue dispensing strip; an embedding position where a magnet is fixed is formed in the backside, and handles are arranged at the two ends of the magnet strip; the varnish containing and immerging strip has the structure similar to that of the glue dispensing strip. With the utilization of the combined jig, the transformer can be switched rapidly in a manufacturing procedure; through the glue dispensing strip and the varnish containing and immerging strip, semi-automation of glue dispensing and varnish immersion of the transformer can be realized, and the glue dispensing and varnish operation of the transformer is changed from single operation to batch operation. Therefore, production efficiency of ER type transformers is increased greatly, and cost is saved.

Description

Technical field [0001] The present invention relates to a combined jig for improving the manufacturing efficiency of small transformers; the present invention also relates to an electronic transformer manufacturing method using these combined jigs. Background technique [0002] As we all know, the common SMD (abbreviation of Surface Mounted Devices) series electronic transformers made of ER small magnetic cores such as ER7.5, ER11.5, ER14.5, etc., have a flat and small structure, good heat dissipation, better magnetic shielding, and easy The characteristics of processing and low cost are widely used in high power density and high integration power supply occasions, especially as power transformers in DC-DC low-power power modules. Most of the transformers using the above-mentioned ER cores still use the traditional skeleton structure. The process is cumbersome and low in efficiency during the manufacturing process. If a fully automatic production line is used, it will lead to low...

AI Technical Summary

Problems solved by technology

[0013] 2. Since the test action in the test section is relatively simple, it will inevitably cause material accumulation in the dispensing section, which seriously affects the takt time and overall efficiency of the transformer production line

[0014] 3. The transformers flow down on the conveyor belt one by one. If the transformers cannot be placed in an orderly manner, they will appear scattered, so it is difficult to match the corresponding automatic dispensing equipment.

[0015] 4. Transformer immersion operation is inefficient and requires employees to deal with them one by one, which is inefficient

The depth of impregnation cannot be guaranteed consistently, so that the quality of transformer impregnation cannot be effectively guaranteed
