Abstract

The invention discloses a manufacturing device of a plastic-encapsulated photoelectric coupler, which comprises a base, a support plate is fixed on the upper end surface of the base, and three support blocks whose rear ends pass through the support plate are fixed on the upper end surface of the base. The upper end of the support block is provided with a conveyor belt and a chip, and the upper end of the support block in the middle is provided with two gold islands for metal lead frame tube legs. Transmission mechanism, the left and right sides of the transmission mechanism are provided with two moving mechanisms that can transport the chips on the conveyor belt to the upper side of the gold island, and the left and right sides of the transmission mechanism are also equipped with two moving mechanisms The coating mechanism for applying conductive glue on the lower end surface of the chip can fully automatically stick the chip to the gold island of the metal lead frame tube leg when forming a plastic-encapsulated photocoupler at one time, without manual sticking, improving Improve work efficiency, save labor, and improve the degree of automation.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a manufacturing device for a plastic-encapsulated optocoupler. Background technique [0002] At this stage, when forming a plastic-encapsulated optocoupler at one time, it is necessary to bond the light-emitting chip and the light-receiving chip to the gold island of the metal lead frame tube leg in advance to facilitate one-time molding; [0003] At this stage, when molding a plastic-encapsulated optocoupler, most of them need to manually debond the chip. In the case of heavy workload, the efficiency is reduced, and when molding a plastic-encapsulated optocoupler, most of the couplers are placed in the same mold. At the same time, one-time molding and manual bonding of chips need to be done many times, which is not efficient. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a manufacturing device for a plastic-encapsul...
