Abstract
The utility model discloses a laser diode fixing structure, comprising a metal supporting sleeve and an installing seat assembled on the metal supporting sleeve, wherein a cylindrical shaft with smooth surface is arranged between the metal supporting sleeve and the installing seat; the two end parts of the cylindrical shaft are symmetrically provided with round corners; the upper end of the metal supporting sleeve is provided with an inverted T-shaped groove hole; a positioning lead-in groove with a square-shaped section is arranged above the groove hole; and the bottom end in the positioning lead-in groove is provided with a blocking part. The laser diode fixing structure adopts positioning and assembling of the smooth cylindrical shaft with two symmetrical ends so as to replace the traditional assembly of metal stamping elastic pieces, and reduce the probability of static shock damage; and in addition, the laser diode fixing structure improves the operating efficiency, after the cylindrical shaft is beaten into the metal supporting sleeve, the pressure is uniform, the elasticity is stable, the radiation is guaranteed, and the round corners of the two ends of the cylindrical shaft can ensure smooth leading in without generating cuttings when being arranged into the metal supporting sleeve.
Description
Technical field
The utility model relates to field of illuminating lamps, is specially a kind of laser diode fixed structure.
Background technology
Laser diode is the core component of optical read head, it is the starting point of whole optical system, therefore the required precision of the location of laser diode and assembling position is very high, usually assemble by artificial in the prior art, because being subjected to the self structure restriction can't carry out automation assembles, thereby operating efficiency is lower, and the static electricity on human body is difficult to avoid fully when manually assembling, and causes that easily the laser diode electrostatic impact causes burning.
The characteristics that high heat is arranged during laser diode work, frequency displacement takes place owing to temperature surpasses threshold value in the laser that diode sends, usually use metal stamping shell fragment 3 and mount pad 2 that laser diode is fixed in the metal support sleeve 1 in the prior art, to guarantee that contact is in time distributed heat closely, as shown in Figure 1, it is big that metal stamping shell fragment 3 is generally specific heat capacity, the kirsite that material is softer, in assembling process,, fall on other optical articles and influence the reading performance of optical head often because of the friction cutting generation metal fragment of metal stamping shell fragment 3 edge burr and metal support sleeve 1.
The utility model content
The purpose of this utility model provide a kind of can automation assembling, do not produce the laser diode fixed structure of chip.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of laser diode fixed structure, comprise a metal support sleeve and be assemblied in mount pad on the metal support sleeve, be provided with a ganoid cylinder axis between described metal support sleeve and the mount pad, the both ends of cylinder axis are arranged with fillet, described metal support sleeve upper end offers the slotted eye of a cross section for " ⊥ " type, the slotted eye top is provided with the location lead-in groove of a cross section for " mouth " type, and location lead-in groove inner bottom is provided with the into portion of ending.
In addition, the surface roughness of described cylinder axis is 1.0S, and the chamfering of two ends fillet is 0.4.
The beneficial effects of the utility model are: use the smooth cylinder axis location assembling of two symmetry, to substitute traditional metal stamping shell fragment assembling, make and originally must be carried out the automation assembling by the engineering of artificial assembling, reduced the link that laser diode contacts with the people, reduce the probability of electrostatic impact damage, and improved operating efficiency, after cylinder axis is squeezed into the metal support sleeve, pressure is average, elasticity stable, it is guaranteed to dispel the heat, can slick and sly the importing when fillet at cylinder axis two ends can guarantee to pack into the metal support sleeve and do not produce smear metal.
Description of drawings
Fig. 1 is the schematic diagram of conventional laser diode guiding structure;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 2, a kind of laser diode fixed structure, comprise a metal support sleeve 1 and be assemblied in mount pad 2 on the metal support sleeve 1, be provided with a ganoid cylinder axis 4 between described metal support sleeve 1 and the mount pad 2, the surface roughness of described cylinder axis 4 is 1.0S, the chamfering of two ends fillet is 0.4, the both ends of cylinder axis 4 are arranged with fillet, described metal support sleeve 1 upper end offers the slotted eye 5 of a cross section for " ⊥ " type, the stria of slotted eye 5 left and right sides is the C0.4 lead angle, slotted eye 5 tops are provided with the location lead-in groove 6 of a cross section for " mouth " type, location lead-in groove 6 inlet portion dual-sides are provided with the R0.5 lead angle, upper side edge is provided with the R0.25 lead angle, location lead-in groove 6 inner bottom are provided with the into portion 7 of ending, when fixing the assembling laser diode, at first laser diode is imported slotted eye 5 by lead angle, lead-in grooves 6 are located in cylinder axis 4 vertical contrapositions then, the R angle self adaptation of the R angle of cylinder axis 4 ends and slotted eye 5 inlet portions imports, cylinder axis 4 is pressed into metal support sleeve 1, arrival stops when ending into portion 7, and laser diode imports at cylinder axis 4 under the internal pressure effect of back metal support sleeves 1 and accurately fixed.
The utility model uses the smooth cylinder axis 4 location assemblings of two symmetry, to substitute 3 assemblings of traditional metal stamping shell fragment, make and originally must be carried out the automation assembling by the engineering of artificial assembling, reduced the link that laser diode contacts with the people, reduce the probability of electrostatic impact damage, and improved operating efficiency, after cylinder axis 4 is squeezed into metal support sleeve 1, pressure is average, elasticity stable, it is guaranteed to dispel the heat, can slick and sly the importing when fillet at cylinder axis 4 two ends can guarantee to pack into metal support sleeve 1 and do not produce smear metal.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
