Abstract
A plastic horn of a welding structure is disclosed. In the 21st century, a laser is widely used in industrial manufacturing. Cutting, welding and other technologies use more and more laser. In order to satisfy a pressure direction and simultaneously because a greatest thickness of a light transmission material located on an upper part during the welding is 3mm, in the traditional laser welding, the light transmission material located on the upper part can be only designed into a sheet shape. Therefore, a design space of a product on a structure aspect is limited. The horn of the utility model comprises a plastic product A (1) possessing a triangle recess structure. The plastic product A is welded with a plastic product B (2) possessing a triangle embossment structure. The horn of the utility model is used for plastic welding.
Description
technical field:
the utility model relates to a kind of loudspeaker of welded plastics.
background technology:
after entering 21 century, laser is widely used in industry manufacture, and it is also more and more that the techniques such as cutting, welding are used laser.Traditional laser welding meet pressure direction with simultaneously due to welding the time above the thickness of light transmissive material be 3mm to the maximum, causing the mentality of designing of top transparent parts can only be sheet, this has just limited to product design space structurally.
the Vibration welding be widely used now, ultrasonic bonding existent defect: in the Vibration welding process, at first, friction welding joint does not produce and melts and solidify metallurgical some relevant weld defects and welding embrittlement phenomenon, as thick column crystal, segregation, be mingled with, crackle and pore etc.; Secondly, axial compressive force and moment of torsion acting in conjunction, in friction-welding surface and near region thereof, have produced some mechanics metallurgical effects, as grain refinement, dense structure, field trash disperse distribute, and " self-cleaning " of friction-welding surface effect etc.; Moreover the friction welding time is short, Zhai， heat affected area, heat affected area tissue is without obviously alligatoring; Ultrasonic bonding is only applicable to the welding between thin plate.
summary of the invention:
the purpose of this utility model is to provide a kind of loudspeaker of welded plastics.
above-mentioned purpose realizes by following technical scheme:
a kind of loudspeaker of welded plastics, its composition comprises: have the plastic part A of triangular shaped recess structure, described plastic part A and the plastic part B with triangular hill structure weld together.
the loudspeaker of described welded plastics, the angle of the triangular shaped recess structure of described plastic part B is 50 ° ~ 70 °, the angle of the triangular hill structure of described plastic part A is 55 ° ~ 75 °.
beneficial effect:
1. the pressure that the utility model makes to be applied to two parts turns to by the structure of commissure, makes two parts produce extruding force at weld, and while having realized welding, the welding condition that weld has pressure, realize laser welding.
2. the utility model is to change by structure at weld, thereby the fixture applied pressure is transferred to face of weld, thereby when reaching welding, pressure is consistent with the direction of laser.
the utility model little to the mechanical impact force of workpiece, do not damage surface of the work, can realize that fully, frock high without dust welding, weld seam visual quality is without wearing and tearing, division, tool expense is low.
the accompanying drawing explanation:
accompanying drawing 1 is the structural representation of the Welding Structure part of this product.
embodiment:
embodiment 1:
a kind of loudspeaker of welded plastics, its composition comprises: have the plastic part A of triangular shaped recess structure, piece number: 1, described plastic part A and the plastic part B with triangular hill structure, piece number: 2 weld together.
embodiment 2:
the loudspeaker of above-mentioned welded plastics, the angle of the triangular shaped recess structure of described material product B is 50 ° ~ 70 °, the angle of the triangular hill structure of described plastic part A is 55 ° ~ 75 °.
embodiment 3:
the loudspeaker of above-mentioned welded plastics, its welding method is: the solder side that will have through the plastic part A of the character of the laser of corresponding wavelength is processed into the triangular shaped recess structure, the solder side do not had through the plastic part B of the character of the laser of corresponding wavelength is processed into to the triangular hill structure, by described triangular shaped recess structure and described triangular hill structure alignment, two vertical planes that laser vertical is aimed at the triangular shaped recess structure of described plastic part A are welded, in laser welding, exert pressure in the back side in the correspondence of solder side, it is 820nm ~ 980nm that laser is selected wavelength, power is 50W ~ 120W.
embodiment 4:
the loudspeaker of above-mentioned welded plastics, its Fundamentals of Welding are: Ear Mucosa Treated by He Ne Laser Irradiation is to soldered workpiece, superposed plastics have the character through the laser of corresponding wavelength, laser passes through its body and mistake, arrival is positioned on the frosting of bottom, and the plastics of bottom do not see through the laser of this wavelength, so laser is absorbed by primer, the heat produced makes the faying face plastic melt, thereby form pad 3, two workpiece is welded together.
Claims (2)
1. the loudspeaker of welded plastics, its composition comprises: have the plastic part A of triangular shaped recess structure, it is characterized in that: described plastic part A and the plastic part B with triangular hill structure weld together.
2. the loudspeaker of welded plastics according to claim 1, it is characterized in that: the angle of the triangular shaped recess structure of described plastic part B is 50 ° ~ 70 °, the angle of the triangular hill structure of described plastic part A is 55 ° ~ 75 °.
