Background technology
Sintering is considered as atom high energy position unstable from system and migrated to the process of free energy extreme lower position.It is thick
Gas-Soliq Particle Systems in film slurry are the powder model systems of high degree of dispersion, have very high surface free energy.Because system is always
Make every effort to reach minimum surface free energy state, so during thick film firing, the total surface free energy of powder model system is inevitable
Reduce, here it is the principle of dynamics of thick film firing.
Solid particle has very big specific surface area, has the complex surface state of irregular and the manufacture in particle
, in the process such as micronization processes, serious crystal defect caused by the machinery that is subject to, chemistry, heat effect etc., system has very
During high free energy sintering, particle is combined by touching, and the contraction of Free Surface, the exclusion in space, elimination of crystal defect etc. are all
The free energy of system can be made reduce, system is changed into state more stable in thermodynamics.This be thick film powder model system at high temperature
The reason for compact structure can be sintered into.
The slurry on silicon chip is dried, the organic component of after-flame slurry, slurry and silicon chip is formed good Ohmic contact.Pass
The sintering furnace of system is divided into multiple temperature from as little as high warm area, and sintering furnace is longer in the length of silicon chip direct of travel, area of dissipation
It is larger, cause radiating in the heating passage of sintering furnace comparatively fast, to cause the waste of the energy, improve production cost.Therefore one is sought

Signal passes to PLC, and subsequent material carries out sub-material at sub-butt ends, and the second material sensor on sub-butt ends is examined to material
Survey, the detection signal is also passed to PLC, PLC is by controlling the action of the pusher motor of feeding distribution mechanism, so as to control sub-butt ends
Action so that sub-butt ends complete the uniform divided flows of material by material diversion to two component material sections.
First material sensor is included positioned at the signal transmitting terminal of splicing deflector chute inwall side and positioned at splicing guide
The signal receiving end of groove inwall opposite side.
Second material sensor is included positioned at the signal transmitting terminal of arc block face epimere and positioned at arc block face hypomere
Signal receiving end.
Compared with prior art, the beneficial effects of the invention are as follows:
The present invention is in the sintered channels of the sintering furnace of short length, using the width of sintered channels, completes the burning of material
Knot, has saved the energy, has reduced production cost.

Operation principle:
Material enters the splicing section of track separation mechanism from sintered channels, and material is detected by first material sensor
(When have material by when, the signal receiving end of first material sensor does not receive the signal of signal transmitting terminal, and material leaves
Afterwards, signal receiving end receives signal again, so as to complete the detection that material passes through, detects the carry out speed of each material and preceding
Spacing between material afterwards), detection signal is passed into PLC, subsequent material carries out sub-material at sub-butt ends, and on sub-butt ends
Two Material Sensors detect to material(When there is material to pass through, the signal receiving end of second material sensor is received through thing
Expect the signal reflected;When passing through without material, the signal receiving end of second material sensor can not receive to be reflected through material
The signal returned, so as to complete the detection of material), the detection signal is also passed to PLC, PLC, can so as to set by calculating
Row scheme, the action of the pusher motor by controlling feeding distribution mechanism, so as to control the action of sub-butt ends so that sub-butt ends are by material
Branch in two component material sections, complete the uniform divided flows sintering of material, so that in the sintered channels of the sintering furnace of short length,
Using the width of sintered channels, the sintering of material is completed, has saved the energy, reduces production cost.
