Combined jig for wire bonding and semi-automatic welding method using the jig

Abstract

The invention relates to a combined tool for lead attachment and a semi-automatic welding method utilizing the tool. The combined tool comprises a lead fixing module, a lead stop module, a product module and a base; the lead fixing module is provided with a plurality of left half unit clamping slots; a threading unit is arranged corresponding to each left half unit clamping slot; the lead stop module is provided with lead stop plates corresponding to the left half unit clamping slots; right half unit clamping slots which are capable of clamping to-be-welded products by matching with the left half unit clamping slots are formed in the product module at intervals; the base can be fixedly arranged on a welding frame, and assembling die insertion slots are formed in the base; according to the welding method, batch automatic welding of product leads is realized; through a standard operation procedure, by matching with automatic welding of an automatic welding machine, welding quality can be ensured completely; various abuses of a manual welding process are eliminated; meanwhile, by adopting the method, the work efficiency is greatly increased, the labor force input is reduced, and scale production and automatic production are realized.

Description

technical field [0001] The invention relates to the field of automatic welding of wire rods, in particular to a combination tool for lead wire welding and a semi-automatic welding method using the tool. Background technique [0002] At present, the lead welding of products in various industries (mainly in the electronics industry) is mostly manual welding, especially for small and micro electronic products. On the welding table of the welding machine, therefore, manual welding is required one by one. Take the microphone as an example. Microphones are widely used in electronic devices such as mobile phones. The shape of the microphone is mostly circular and the size is generally small. There are generally 2-3 pads on the back of the circular shell of the microphone. Each pad A lead wire needs to be welded on the board, and is electrically connected to the device through the lead wire. [0003] Microphones and other small electronic products have high requirements on welding...

Problems solved by technology

However, after going online, the factors of human factors causing unstable welding quality are also very high, making the production cost generally high

At the same time, in the manual welding process, the welding time and the amount of tin delivered cannot be precisely controlled, and individual welding techniques are also different, which may easily lead to problems such as poor welding quality, waste of welding materials, and tin slag pollution.

In addition to the above, the biggest defect of manual welding is the problem of low work efficiency and high labor cost. With the continuous increase of large-scale production, the problems exposed by manual welding process will become more and more serious.
