In recent years,
laser processing, industrial robots, digital control as the representative of
advanced technology is constantly promote the upgrading of the automotive
industry, and as an advanced laser processing methods, destined to bring a
revolutionary breakthrough for the development of the automotive industry.
Laser processing
technology has penetrated into all aspects of automobile manufacturing, ranging
from welding, cutting, drilling, marking, heat treatment and forming, even to
the micro-processing and other fields of electronic systems.
Laser welding
Laser welding,
as its high energy density, small deformation, narrow heat-affected zone, high
welding speed, easy to achieve automatic control, no subsequent processing,
etc., has become an important means of automobile manufacturing.
Car body chassis
plus a total of hundreds of thousands of parts, how to connect it together has
a direct impact on the vehicle body rigidity, the use of laser welding can take
almost all the different thickness, grade, type and grade of the metal material
They are connected together, in improving productivity and quality, while also
increasing the vehicle design and material selection flexibility.
Laser welding
can be used in place of more automakers casting stamping, with a continuous
laser seam weld place of the dispersion of the points, you can reduce some of
the lap width and the reinforcing member, reduces the volume of the body
structure itself, thereby reducing the weight of the body to meet the
requirements of energy saving vehicles.
Laser welding
can also improve the assembly precision of the vehicle body, the vehicle body
rigidity increased by 30% and increase the safety of the vehicle body. In
addition, the use of laser welding can also reduce car body manufacturing
process of stamping and assembly costs and shorten the production cycle, reduce
the number of parts and improve the degree of integration of the body.
Laser Marking
Automobile and
parts production, the identity is the basis for the establishment of quality
traceability and recall, by way of marking to build cars and parts unique
identity is very critical. Cars marking its high efficiency and adaptability as
well as permanent has been more widely used. Laser marking is the use of high
energy density laser illumination of a workpiece, so that the surface material
vaporization or color changes in chemical reaction, thus leaving one kind of
marking method of permanent marker.
Characteristics
of non-contact laser marking process, at any profiled surface marking, no
deformation of the workpiece and the internal stresses. Modern automotive parts
using a variety of materials, including metals, plastics, glass, ceramics, wood
and leather, while the use of a laser can be perfect on the surface of all of
these materials will be marking.
Of course, laser
technology in automotive applications is not limited to this, it also relates
to the drilling, heat treatment, surface coating, glazing, forming, remelting,
model making and many other micro-machining technology, processing and
manufacturing of products involved each field.
One hundred
thirty years, the social role of the car has undergone tremendous changes.
Today, the car is not just a simple means of transport, it has been deeply
integrated into people's lives and work.
With the
development of new energy vehicles, manufacturing of the automotive industry
will be some new changes, and laser processing technology will infuse more
vitality.
