Description
Technical field
The invention belongs to laser welding technology field, especially relate to a kind of capsule endoscope shell welder and
Method.
Background technology
Laser welding is the laser beam utilizing high-energy-density a kind of high-efficiency and precision welding method as thermal source.Laser is made
For one welding thermal source, there is the advantages such as collimation is excellent, beam energy density is high, the zone of action is little.In welding process,
The light path system consisted of reflecting mirror, lens or optical fiber, focuses on to-be-welded region by the light beam that laser instrument produces, and forms heat
Active region, makes melt material phase counterdiffusion, and in process of setting subsequently, parts to be welded are i.e. connected.
Compared with traditional macromolecular material welding manner (hot plate type welding, ultrasonic bonding), laser welding technology master
The advantage having following several respects:
(1) welding that is accurate, firm and that seal (airtight and water-tight) can be generated, and Degradation of Polymer Materials is few,
The chip produced is few, and the surface of goods can link together around weld seam closely.
(2) easily controllable, there is good adaptability, the workpiece that solderable size is little or contour structures is complicated.
(3) vibration stress and the thermal stress of goods are greatly reduced.
Due to the advantage that laser welding technology is unique, it is successfully applied in the precision welding of macromolecular material.
Capsule endoscope, English name: capsule endoscopy, is a kind of endoscope making capsule shape, and it is
It is used for checking the Medical Instruments of human body intestinal canal.Capsule endoscope can enter human body, for spying upon human body the intestines and stomach and esophagus position
Health status.Can be used to help doctor that patient is diagnosed.Typical capsule endoscope is made up of seven parts, transparent outer cover,

Parts, for the mechanical part of Miniature surgical.Major part capsule is only integrated with one or more a small amount of functions therein at present.Should
Product completes gastrointestinal tract image check by oral intelligent capsule；Overcome traditional pusher endoscope volume big, detected
Journey is painful, is not suitable for the defects such as old age, slim and frahile and dangerous patient；Have volume little, lightweight, check convenience, hurtless measure, nothing
Painful, without cross infection, do not affect the advantages such as person under inspection's normally work.The 4th mileage being described as in digestive endoscopy development history
Upright stone tablet, " goldstandard " that disease of intestine checks.
China, in the research of capsule endoscope, also achieves certain achievement, but does not the most release the product of maturation.
At present, the whole world has had patient up to ten thousand to employ capsule endoscope technology to check.Capsule endoscope can check small intestinal, no
The disease that the conventional endoscope such as obvious gastrointestinal hemorrhage, anemia, gram Duo Sishi are sick cannot effectively check, will become endoscopy
Main stream approach.
Owing to capsule endoscope volume is little, the biggest with common drug capsules；And internal structure is complicated；To sealing
Require higher；Shell generally uses digestion harmless and is difficult to the macromolecular material digested, therefore its shell encapsulation
It it is a technical barrier.
Therefore need badly in the middle of prior art and want a kind of novel technical scheme to solve this problem.
