In the electronics industry, many companies will encounter the problem of enameled wire welding, because enameled wire is coated with one or more insulating coatings + materials on the surface of the conductor, and forms a wire with an insulating layer after baking and cooling. Therefore, in the production of electronic components, it is often necessary to solder the lead-out contacts of the enameled wire. Since current cannot pass through the insulation layer of the enameled wire, resistance welding cannot be performed, so direct welding of the enameled wire is a technical problem that has long plagued the electronics industry. This technology sets the appropriate three welding parameters by adding the ohmic contact at the extreme of the flat electrode to achieve the same pulse output to remove the paint and weld the enameled wire, and directly weld the enameled wire in a single-side welding mode Welding of the lead contacts of the enameled wire of components provides a new and indispensable welding technology.

Enameled wire spot welding machine method: enameled wire welding mainly includes enameled wire and circuit board gold plated plate welding, enameled wire and silver plated, tinned, nickel plated and other materials welding, enameled wire and copper alloy welding, etc. The original soldering methods mainly include dip soldering and manual soldering iron soldering. Immersion tin soldering has the disadvantages of easy short-circuiting, manual soldering iron soldering has the disadvantages of slow soldering efficiency, and some need to remove the paint in advance, which seriously affects the soldering efficiency, and all have a large amount of tin and high cost. And some of them can not meet the environmental protection requirements and process requirements of European and American customers. Solder soldering has the risk of large resistivity and easy to fall off. Now it is also useful for welding with AC spot welding machine and capacitor storage spot welding machine. Since the energy requirements of precision enameled wire welding are very high, a small or large energy will cause virtual welding. Especially when used with automatic spot welding machines, it requires higher energy and speed.

This requires a spot welding machine with more precise current control and time control. The inverter DC JYD-02L precision spot welding machine of Guangzhou Jingyuan Electronic Equipment Co., Ltd. is designed to solve these various welding problems for customers. It has good welding effect, high yield, strong consistency, and eliminates heat accumulation to the greatest extent.

According to customer requirements, 0.4mm enameled wire is welded on the tinned copper sheet. After our engineers' thinking and decision to use JYD-02L inverter DC spot welding machine for welding, we have achieved good welding results after many debugging And has been recognized and valued by customers.

JYD-02L features:

⒈JYD-02L is dedicated to enameled wire welding.

⒉The built-in micro switch triggers welding to ensure welding consistency

⒊Built-in compression spring can quickly follow the deformation of the workpiece during the welding process

⒋Scale display pressure, easy to adjust and quality management

⒌Compact structure, stable pressure

In addition, during the use of the welding head, the surface will become dirty due to the influence of the insulating paint and other substances on the surface of the material (such as flux). Surface dirt affects the heat transfer of the welding head to the welding area, resulting in poor welding. After welding a certain number of times (the lowest number obtained in the experiment), the surface of the welding head needs to be cleaned.

Pay attention to the correct cleaning method, do not damage the structure of the welding head, and do not have a large impact on the life of the welding head.

6 Applicable wire diameter of enameled wire:

This welding method is suitable for welding small enameled wire. If the enameled wire is too thick, it will cause too much loss to the welding head and has no practical economic significance. If the wire diameter is large, it can be peeled off without welding.
