Abstract
The utility model discloses a laser marking machine common light path coaxial structure, including first reflector plate, second reflector plate, limit baffle, filtering lens, protection casing, sensor fixing base, first reflector plate is fixed in the bottom of sensor fixing base, and is parallel with the second reflector plate, the second reflector plate is fixed on the inner wall of protection casing, limit baffle is located the top and the bottom of protection casing, filtering lens installs the top and the bottom at the protection casing, the sensor fixing base is installed on the lateral wall of protection casing. The first reflector reflects incident light to the second reflector, and light reflected by the second reflector vertically passes through the center of the filter lens downwards and irradiates the surface of the object to be measured. The utility model discloses simple structure lets marking machine seek burnt, visual detection is more accurate, convenient, is applicable to the laser marking machine of each type.
Description
Technical Field
The utility model belongs to a laser marking machine is light path coaxial structure altogether, supplementary laser marking machine automatic focusing system, visual detection system are with laser light path altogether, and it is more convenient to use, detect more accurately.
Background
The traditional laser marking machine automatic focus searching and visual detection device at present comprises a paraxial vertical device and a paraxial inclined device, wherein a sensor is vertically fixed on one side of a vibrating mirror by the paraxial, a measuring point of the paraxial vertical device is not at the center of the vibrating mirror, and the paraxial vertical device needs to be measured and reprocessed firstly when a small workpiece is processed.
Disclosure of Invention
The utility model provides a laser marking machine common light path coaxial structure has solved laser marking machine and has sought burnt automatically, visual detection is inconvenient, inefficiency down, measure the inaccuracy scheduling problem, this simple structure, seek burnt more convenient, detect accurate, swift, be applicable to each type of laser marking machine.
The utility model discloses a following mode of purpose accessible realizes: the utility model provides a laser marking machine common light path coaxial structure, its characterized in that: including first reflection lens, second mirror, limit baffle, filter lens, protection casing, sensor fixing base, first reflection lens is fixed in the bottom of sensor fixing base, and is parallel with the second mirror, the second mirror is fixed on the inner wall of protection casing, limit baffle is located the top and the bottom of protection casing, filter lens installs at the top and the bottom of protection casing, the sensor fixing base is installed on the lateral wall of protection casing. The first reflector reflects incident light to the second reflector, and light reflected by the second reflector vertically passes through the center of the filter lens downwards and irradiates the surface of the object to be measured.
The utility model has the advantages of, overcome the former laser marking machine seek burnt, visual detection light path disalignment arouse seek burnt inconvenient with measure difficult points such as inaccuracy, this laser marking machine common light path coaxial structure lets automatic seek burnt simpler with visual detection, measure more accurate, use more convenient, solved in the past marking machine automatic seek burnt problem that exists with visual detection.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1: an internal structure schematic diagram of a common-light-path coaxial structure of a laser marking machine.
FIG. 2: an external structure schematic diagram of a common-path coaxial structure of a laser marking machine.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
As shown in fig. 1 and 2: the utility model relates to a laser marking machine common light path coaxial structure, including first reflector plate 1, second reflector plate 2, limit baffle 3, filter lens 4, protection casing 5, sensor fixing base 6.
As shown in fig. 1, the first reflector 1 is fixed at the bottom of the sensor holder 6, is 135 degrees from the horizontal, and is parallel to the second reflector 2. The detection light of the sensor vertically irradiates the first reflector 1, and horizontally irradiates the second reflector 2 after being reflected.
As shown in fig. 1, the second reflector 2 is fixed on the inner wall of the protective housing 5 through a limiting baffle 3, the limiting baffle 3 is located at the top and the bottom of the protective housing 5, the second reflector 2 forms 135 degrees with the horizontal plane, and the reflected light of the first reflector 1 vertically passes through the filter 4 downwards after being reflected by the second reflector 2.
As shown in fig. 1, the filter lens 4 is located at the top and bottom of the protective casing 5, and can block floating dust from contaminating the lens, and also can filter some stray light to prevent measurement and identification from being interfered. The sensor fixing seat 6 and the limiting baffle 3 can be installed on the side wall of the protective shell 5, and a screw penetrates through a thread hole in the top to be installed on a field lens of the laser marking machine.
As shown in fig. 2, a sensor fixing base 6 is installed at a side of the protective housing 5 for mounting the sensor. The sensor is electrified, and the detection light rays vertically downwards penetrate through the center of the filter lens 4 after being reflected by the first reflector lens 1 and the second reflector lens 2 and irradiate the surface of the object to be detected, so that the light rays of the detection light rays and the laser are coaxial, and the purposes of measuring and identifying and marking the same position with the laser are achieved.
The utility model provides a laser marking machine is automatic to seek burnt in the past, visual detection and laser light path disalignment, the processing that arouses is inconvenient, detect the inaccuracy scheduling problem, this laser marking machine common light path coaxial structure lets laser marking machine automatically seek burnt more accurate, the use is more convenient with visual detection.
The above description is only for the preferred embodiment of the present invention, and not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
