Abstract
The present invention discloses a laser treatment method for tooth brushes and brushes, which has the technical scheme that the end surfaces of brush teeth are illuminated by laser, and thus, the temperature in a minimum area below the end surfaces of the brush teeth is rapidly increased; the illumination is stopped until the brush teeth are melted; then, the brush teeth are formed into mushroom tooth heads by cooling the laser is continuously illuminated in the direction of the brush teeth and are vertically illuminated on the end surfaces of the brush teeth; the whole end surface of the brush teeth is the photosynthesis area, the laser energy density of the end surface edge of the brush teeth is not less than the 80% of the laser energy density of the middle part, and the power density of laser illumination of the end surface of the brush teeth is 38 to 114 W/CM + 2. The present invention has the advantages of convenience, easy implementation, high photo-thermal efficiency, low energy consumption, high processing speed and good effect.
Description
The present invention relates to the processing method of toothbrush and brush brush tooth, especially relate to the laser processing method of toothbrush and brush brush tooth.
Toothbrush and brush brush increment face forms all and is formed by the machinery knives cutting now, because the shear extrusion effect of mechanical force, at unavoidable many wedge angles and the burr of forming of brush increment face.If brush teeth with such toothbrush, all very harmful to gum and tooth glaze, more be unwell to children and Ya disease patient's use.
The purpose of this invention is to provide a kind of laser processing method of eliminating toothbrush and brush brush increment face wedge angle, burr.
The laser processing method of toothbrush and brush brush tooth is: power density is 38～114 watts/centimetre
2Carbon dioxide laser, vertically be radiated on the nylon bruss increment face of toothbrush and brush continuously, make under the brush increment face in the very small region, temperature raises rapidly, until fusing, promptly stops irradiation, is cooled to mushroom tooth head then.Said laser also has YAG laser, nd glass laser, metallic vapour laser, carbon monoxide laser, PRK and argon laser.The beam mode of laser is basic mode (TEM
00).
Laser beam comes out to adjust spot size through optical system again through speculum, and just in time the facewidth with toothbrush is identical, to form the photothermy that adapts with brush increment face, then the toothbrush of well cutting is sent into laser irradiation area by conveyer belt.Laser vertically is radiated on the brush increment face continuously, the light action area is whole brush increment face, the laser energy density at brush increment face edge be not less than the position, intermediate portion laser energy density 80%, the feed speed of brush hair on the neck is determined by the energy density that shines on the brush increment face.The feed speed of brush hair on the neck is generally 3～12 cels.
Test shows that employing power is 60 watts carbon dioxide laser, and spot diameter is 1cm, and power density is 77 watts/centimetre
2, the feed speed of brush hair on the neck is 7.5 cels, and the toothbrush that has wedge angle and burr is carried out laser treatment, has become smooth spherical or hemispheric tooth head.
The laser of some wavelength, be mainly infrared, near infrared light, with nylon, nonmetallic substances such as plastics have strong photothermy, when these nonmetallic substances, the laser of the absorbing wavelength that is matched, when the irradiation of tooth direction is brushed on the edge, promptly absorb a large amount of light energies, simultaneously owing to nonmetallic bad thermal conductivity, in the following very small region of brush tooth surface, temperature raises rapidly, until fusing,, stop irradiation as this moment, melt portions on the brush tooth head is cooled off rapidly, because melted material surface tension, cooling back just form bright and clean and regular little bulb naturally, the material of brush tooth is generally: nylon yarn, artificial silk, polyethylene, polypropylene, acetate polymer.
Realize that key of the present invention is to regulate spot size, select suitable laser power, reach the brush hair on the neck feed speed that adapts with laser power.The adjustment of spot size will guarantee that each rooted tooth on the brush can both obtain satisfied processing.Because laser energy is Gaussian distribution on beam cross section, therefore will guarantee to brush the suffered energy density in tooth marginal portion is not less than 80% of mid portion, otherwise big or small uneven bulb can occur.Laser shines the energy density on the brush tooth, should match with brush hair on the neck feed speed, feed speed is certain, and laser energy density is too high, bulb on the brush tooth is just too big, even between the brush tooth adhesion phenomenon being arranged, opposite energy density is too little, then can not eliminate burr and wedge angle fully, can not form smooth, therefore suitable bulb before producing, grasp these parameters from test.
Toothbrush or brush by after the present invention's processing have many advantages: from appearance, seemed to spread the sparkling and crystal-clear bright pearlet of one deck on the brush increment face, and under light, visible dribs and drabs, glittering, feel is also fine; Use from protecting tooth, has great improvement than former toothbrush, this also is a main task of the present invention, at first it has had no injury to gum and tooth glaze, and the little bulb of bright and clean slyness also has massage effect to periodontal tissue on the tooth head, help the blood circulation of around teeth tissue, improve its immunocompetence, therefore tooth disease patient is had certain health protection and therapeutic action, healthy person is also worked the strong tooth effect of tooth of protecting; From the effect that cleans the teeth, the toothbrush after the processing, better effects if cleans the teeth, because in the process of brushing teeth, brush the bulb on the tooth one by one, just as one rake, can be admirably the swill between the tooth seam, on the facing, gum be cleared, effect is obviously good than untreated toothbrush; Use from toothbrush, brush tooth head is all keeping bulb from start to finish, so its health care massage effect is new and old as one, can be with the use of toothbrush, and depreciation and disappearing.
The invention process is got up, and is convenient and easy, and device is simple, is convenient to operation, safe and reliable.Select suitable optical maser wavelength, interact with the brush tooth, make photo-thermal efficient height, energy consumption is low.The laser of certain power and tooth head interact, and bulb forms at short notice fast.Photothermy only limits to extremely shallow zone, can ignore other some effects of toothbrush.Bulb forms stable, and geomery is easy to control, the entire process process cost is extremely low, and speed is very fast, does not produce any adverse effect, is suitable for the large-scale production of toothbrush and brush manufactory flow production line, has excellent economic.
