Because the marking laser module provided by the embodiment of the invention refers to the adjusting platform, the marking laser module provided by the embodiment of the invention also has the advantage of the adjusting platform.
As shown in fig. 10 and 11, the reticle laser module provided in the embodiment of the invention includes a housing 810, a driving circuit board 820, a laser source 830, a beam expander 840, a collimator lens holder 850, and a collimator lens 860. The laser light source 830, the beam expander 840, the collimator lens holder 850, and the collimator lens 860 form a laser point light source system. The base 100 of the adjustment platform is integrally formed with the housing 810. The reticle laser module further comprises a glass tube 870 and a cone mirror 880, wherein one end of the glass tube 870 is arranged on the adjusting platform, and the other end of the glass tube 870 supports and fixes the cone mirror 880.
The driving circuit board 820 is a driving system. The laser light source 830 may be a laser diode directly emitting light as the laser light source 830, or may be a combination of a laser diode and a laser crystal as the laser light source 830; the beam expander 840 mainly plays a role in expanding the beam of the laser source 830, and is convenient for compressing the divergence angle of the laser beam, and the beam expander can be arranged or not; the collimator lens holder 850 is mainly used for loading the collimator lens 860, and enables the collimator lens 860 to be matched with the housing 810, and may or may not be provided; the collimator lens 860 mainly plays a role in compressing and collimating the beam divergence angle of the laser light source 830.
The shell 810 is used as an important support body of the whole structure and is in interference fit with the light source and the lens system; the cone mirror system is fixed by gluing. The marking laser module not only can enable the cone mirror to move upwards in the horizontal direction to adjust the overall uniformity of the line, but also can enable the cone mirror 880 to perform pitching adjustment in the vertical direction through the adjustment platform, so that the line straightness reaches the adjustable purpose, the accuracy of the line straightness is improved, the difficult problem that the requirement of the annular module on the coaxiality of a light source is high can be solved, and the difficult problem that the module cannot be reworked after the line straightness is changed is solved.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
