Problems solved by technology

This kind of ultrasonic welding machine that relies entirely on manual positioning has low work efficiency and slow speed. A skilled operator can only weld 0.5 to 0.7 lines per second on average, and the operator's labor intensity is high; because each solder joint needs to be manually inspected under a microscope Visual positioning, the technical level of the operator has a great influence on the welding quality, and factors such as operator fatigue and vision changes will cause fluctuations in welding quality
Therefore, it is difficult to ensure the consistency of products welded by manual ultrasonic welding machines in terms of quality.

Abstract

The disclosed positioning system includes welding set, precision 3D servomechanism composed of 3D servomotor and worktable, micro optical unit, microcomputer, and digital pick-up head. The system possesses functions of automatic image recognition and microposition, and operational functions: determining position of welding spot by mouse click, automatic storing calculation, reaching to the designated position, and completing welding. It is possible to modify manual ultrasonic welding machine to automatic welding machine by using the invention. Comparing with manual welding machine, the system possesses advantages: lowering labors intensity, raised work efficiency to 4 - 6 times, high positioning precision (í‚0.005mm), good welding quality, and easy of use etc. Comparing with automatic ultrasonic welding machine, the system uses mouse to replace trackball so as to raise positioning precision, lower cost, and provide intuitive operation.

Description

(1) Technical field [0001] The invention relates to the field of welding, in particular to a welding device with a microscopic image automatic calculation and positioning system and its operation mode. The system automatically calculates, analyzes and positions the welding spot of a workpiece, and completes welding. (2) Technical background [0002] None of the existing welding equipment has an automatic calculation and positioning system for microscopic images. For example, a manual ultrasonic aluminum wire (or gold wire) welding machine is a welding production equipment for the semiconductor device post-process (COB). It is mainly used in digital tubes, dot matrix Soldering of leads in semiconductor devices such as boards, integrated circuits, thick film circuits, and transistors. The working steps of welding semiconductor devices with a manual ultrasonic welding machine are as follows: fix the workpiece on the worktable, the operator directly observes through the microsco...
