Automatic solder terminal straightening machine

Abstract

The invention relates to an automatic solder terminal straightening machine; a servo motor, a feeding mechanism, a blanking mechanism, a welding part, a flux box, a terminal straightener and a programmable logic controller (PLC) are arranged on a console; a plurality of mechanical arms are arranged on the servo motor; the welding part consists of a low-temperature crest soldering furnace and a high-temperature crest soldering furnace; and the other ends of the mechanical arms are arranged on the upper ends of the flux box, the terminal straightener, the blanking mechanism, the low-temperature crest soldering furnace and the high-temperature crest soldering furnace. According to the automatic solder terminal straightening machine, the structure is reasonable, the automation degree is high, such processes of flux adding, welding and terminal straightening can be completed automatically, the efficiency can be improved by more than five times and the used amount of tin can be saved by at least 20 percent compared with those of an ordinary half-manual process, so that the product reliability is improved, and the labor intensity of a worker and the dependence on the proficiency of the worker are greatly reduced.

Description

technical field [0001] The invention relates to the field of electronic parts manufacturing, in particular to an automatic solder terminal straightening machine. Background technique [0002] In recent years, many processes of high-frequency transformers and inductors have made great progress in mechanization, but the key process of welding has not made substantial progress in automation. Due to the need for high-temperature (420-550°C) welding between windings and terminals, the high-temperature solubility of plastics often causes the implanted metal terminals of high-frequency transformers and inductors to be skewed or even loose, making it difficult to meet industry standards. According to the current process, the terminals need to be manually trimmed or mechanically vibration corrected before use / shipment, which is not only a waste of time, but also causes serious damage to the metal terminals, its mechanical strength will be greatly reduced, and subsequent solderability...

Due to the need for high temperature (420-550°C) welding between windings and terminals, the high-temperature solubility of plastics often causes the implanted metal terminals of high-frequency transformers and inductors to be skewed or even loose, making it difficult to meet industry standards

According to the current process, the terminals need to be manually trimmed or mechanically vibration corrected before use / shipment, which is not only a waste of time, but also causes serious damage to the metal terminals, its mechanical strength will be greatly reduced, and subsequent solderability may also be affected by the damaged parts. Oxidized and difficult to solder
