The purpose of this utility model is to provide a kind of camera lens dust guard be applied in laser marking technique.
The camera lens dust guard that what the utility model provided be applied in laser marking technique; comprise the protective lens be arranged at above laser lens; described protective lens has transparent area; the top of described protective lens is provided with motor, the rotating shaft of described motor is connected with the brush for cleaning described transparent area.
The such scheme that the utility model provides, is provided with protective lens, prevents dust deposit on laser lens.In addition, after the mark operation carrying out a period of time, drive brush to rotate and wiping is carried out to protective lens, make the transparent area of protective lens have good light transmission, carrying out smoothly of mark can be ensured.
Detailed description of the invention
With reference to the accompanying drawings embodiment of the present utility model is described.The element described in an accompanying drawing of the present utility model or a kind of embodiment and feature can combine with the element shown in one or more other accompanying drawing or embodiment and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of parts that have nothing to do with the utility model, known to persons of ordinary skill in the art and process in illustrating.
The structural representation being applied to the camera lens dust guard in laser marking technique that Fig. 1 provides for the utility model embodiment.As described in Figure 1; the camera lens dust guard that what the utility model embodiment provided be applied in laser marking technique; comprise the protective lens 8 be arranged at above laser lens 1; protective lens 8 has transparent area; the top of protective lens 8 is provided with motor 5, the rotating shaft of motor 5 is connected with the brush 7 for cleaning transparent area.
Wherein, transparent area as referred to herein can be the actual region for printing opacity be formed in protective lens 8, may also be and is arranged in protective lens by the form of virtual grate, for the region for laser penetration.Such as but not limited to, it is lighttight for protective lens 8 having one or more region be all the other regions of printing opacity.Can also be whole protective lens 8 be all printing opacity, just when work, the region that laser passes be defined as transparent area.
The such scheme that the utility model provides, is provided with protective lens 8, prevents dust deposit on laser lens.In addition, after the mark operation carrying out a period of time, drive brush 7 to rotate and wiping is carried out to protective lens 8, make the transparent area of protective lens 8 have good light transmission, carrying out smoothly of mark can be ensured, and improve operating efficiency and utilization rate of equipment and installations.
Further, based on above-described embodiment, brush 7 is connected with the first sweep-up pipe 6, rotate at brush 7 and carry out in the process of dedusting, the dirt thing adopting aspirator to be brushed by brush 7 by the first sweep-up pipe 6 is siphoned away, and improves cleaning effect.
Further, based on above-described embodiment, brush 7 is connected with the shower nozzle 3 for spraying cleaning agent to protective lens 8, rotates and carries out in the process of dedusting, can spray cleaning agent to clean by shower nozzle 3, to improve cleaning effect at brush 7.Cleaning agent is such as but not limited to selecting IPA (Iso-Propyl alcohol, isopropyl alcohol).
Further, based on above-described embodiment, protective lens 8 is fixedly installed on the top of laser lens 1, and motor 5 slides in the horizontal direction and is arranged at above protective lens 8.Adopt this kind of structure, linear drive apparatus can be adopted to carry out drive motors 5 and move in the horizontal direction, when carrying out clean, horizontal drive motor 5 make brush 7 move to transparent area carry out rotation clean, after clean end, horizontal drive motor 5 makes brush 7 leave transparent area, to carry out ensuing etching.Wherein, linear drive apparatus can be, but not limited to as cylinder 4 or electric pushrod.
Further, based on above-described embodiment, protective lens 8 only can be provided with a transparent area, transparent area is just to laser lens 1, and the laser penetrated from laser lens 1 is radiated at the position printing mark through transparent area.
Further; based on above-described embodiment; as shown in Figure 2 and Figure 3; protective lens 8 rotates the top being arranged at laser lens 1; protective lens 8 has multiple transparent area 10, multiple transparent area 10 is evenly arranged along the pivot center of protective lens 8, and the top of protective lens 8 is provided with fixed mount 11; motor 5 is fixedly connected on fixed mount 11, and brush 7 and laser lens 1 shift to install.Mentioned herein shifting to install refers to, brush 7 is with on the no longer same straight line of laser lens 11, and also namely brush 7 can not block laser lens 11.Such as but not limited to, in protective lens 8 all be provided with three transparent areas 10, press and be counterclockwise followed successively by a transparent area, No. two transparent areas and No. three transparent areas.During use; when a transparent area be positioned at identify above laser lens 1 time; brush 7 is positioned at No. two transparent areas; to clean two number areas under control; after work a period of time (being such as after one or more pieces chip identifications complete), rotate protective lens 8, make No. two transparent areas be positioned at above laser lens 8; and No. three transparent areas are positioned at cleaning position, can be cleaned by brush 7.Adopt aforesaid way, can increase work efficiency.
Further, based on above-described embodiment, the side of protective lens 8 is provided with blower 2 and the second sweep-up pipe 9, and the outlet of blower 2 and the suction inlet of the second sweep-up pipe 9 are placed in the both sides of protective lens 8, and just to setting.Dried by blower 2, dust is suspended in the air, prevents dust deposit, and, absorbed the dust of suspension by the second sweep-up pipe 9, improve dust removing effects, ensure that normally carrying out of laser marking operation.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
