Laser welding device and welding process for engine control module

Abstract

The invention relates to the field of engine control module laser welding, in particular to an engine control module laser welding device and process, comprising a laser welding machine which is provided with a laser welding end for laser welding of a control module; according to the laser welding method and device for the engine control module, a manipulator is replaced by the first embodiment to take down and place the control module, the manufacturing cost is reduced, and when the control module is welded, the control module can be conveniently and rapidly welded, and the welding efficiency is improved. A worker can place another control module, a push ring in the second embodiment drives a contact column to move up and down, an electric push rod is replaced for pushing, the effect that the control module is pushed to be inserted into a material guide frame can be achieved, in addition, the speed can be automatically adjusted according to the work placing speed of the worker, and collision is avoided.

Description

technical field [0001] The invention relates to the field of laser welding of an engine control module, in particular to a laser welding device and a welding process of an engine control module. Background technique [0002] The engine control module, also known as ECM, is the core component of engine control. According to the input information of each sensor, it controls the fuel injection and ignition timing of the engine, and provides the best control instructions for other output devices. The welding of the engine control module usually adopts the method of laser welding. The efficiency of laser welding is usually determined by the corresponding welding device. For example, Chinese patent application number: CN202021626653.8 discloses the connection structure of the engine controller. Laser welding is performed on the mating joint of the flange and the second flange, but the traditional method is often used when welding them. The traditional method is: place the positio...

AI Technical Summary

Problems solved by technology

[0003] 1. When welding the control module, workers cannot place another control module and can only wait aside, which reduces the work efficiency of workers;

[0004] 2. Workers need to wait for the control module to cool down before removing it, which will also waste the working time of workers;

[0005] 3. It will be a waste of time for workers to remove it by workers and place it in the guide frame for collection. If the manipulator is used to take it down and place it for collection, although it can save the physical strength and time of the workers, but due to the mechanical hand The working speed is constant. When the worker's placement speed increases, the working speed of the manipulator cannot be accelerated, which will affect the production efficiency
