Description

Technical Field

[0001] The utility model relates to the technical field of lasers, in particular to an automatic focusing laser with a cleaning reflector structure. Background Art

[0002] A laser is a device that can emit lasers. Due to its various outstanding characteristics, it has been quickly used in industry, agriculture, precision measurement and detection, communications and information processing, medical treatment, military affairs, and other fields, and has caused revolutionary breakthroughs in many fields. Lasers are also commonly used in laser marking machines. At present, during laser marking, the laser often uses an automatic focus mechanism to focus on the marking material.

[0003] When processing objects, the laser will automatically focus. However, when the laser is in use, there may be dust and dirt on the laser reflective surface. If the dust and dirt are not cleaned regularly, the accumulation will increase and may affect the focus accuracy, especially for focusing with micron or even nanometer accuracy. If dust and dirt accumulate in large quantities, it may cause autofocus failure. Usually, the staff cleans it manually, which is time-consuming and laborious. In addition, the staff often forget to clean it regularly and wait until the focus is affected before cleaning it, which reduces work efficiency.

[0004] To this end, we propose a laser with focal autofocusing with a clean-up mirror structure. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1-6 The utility model provides a technical solution: a laser with auto-focusing function and a cleaning reflector structure, comprising a workbench 1, an auto-focusing laser 5 is fixedly installed at the center of the top rear side of the workbench 1, the auto-focusing laser 5 comprises a galvanometer scanning system 2, the galvanometer scanning system 2 comprises a housing 21 and a reflector body 22, and a shielding cover assembly 3 is movably installed at the bottom of the housing 21;

[0027] The shielding cover assembly 3 includes a cover 31, a slide bar 32 is fixedly installed on the top of one side of the cover 31, a slide groove 33 adapted to the slide bar 32 is opened at the bottom of the shell 21, the cover 31 is slidably installed in the slide groove 33 through the slide bar 32 and slidably installed at the bottom of the shell 21, and a clamping assembly 34 is provided at the center of one side of the bottom of the shell 21 away from the slide groove 33;

[0028] When the autofocus laser 5 is not needed, slide the cover 31, and the cover 31 slides on the bottom of the shell 21 under the sliding cooperation of the slide bar 32 and the slide groove 33, and closes the cover 31. By setting the cover 31, dust can be effectively prevented from falling on the surface of the reflector body 22, and a large amount of dust can be prevented from falling on the reflector body 22 to affect the focusing of the autofocus laser 5.

[0029] A cleaning assembly 4 is provided at the bottom of the housing 21 corresponding to the position of the reflector body 22;

[0030] The cleaning assembly 4 includes a cleaning block 41, a second gear 43 and a connecting rod 45. The connecting rod 45 is movably sleeved on the cleaning block 41. The cleaning block 41 is rotatably mounted on the bottom of the housing 21 at a position located at the reflector body 22 through the connecting rod 45. The top of the connecting rod 45 is rotatably mounted on the bottom of the housing 21. A gear 1 42 is fixedly mounted on the top of the connecting rod 45. The gear 1 42 is meshed with the gear 2 43. The gear 2 43 is rotatably connected to the bottom of the housing 21 through a rotating shaft.

[0031] A rack 44 is fixedly mounted on one side of the bottom of the cover 31 near the second gear 43, and the rack 44 meshes with the second gear 43;

[0032] The focusing accuracy of the autofocus laser 5 is in the micrometer or nanometer level.

[0033] When the autofocus laser 5 is not in use, the cover 31 is slid closed. When the cover 31 is slid closed, the cleaning block 41 just covers the reflector body 22, effectively preventing dust from falling on the reflector body 22. When the autofocus laser 5 is in use, the cover 31 is slid closed. While sliding the cover 31, the rack 44 drives the gear 2 43 to rotate, and the gear 2 43 drives the gear 1 42 to rotate, indirectly driving the cleaning block 41 to rotate with the connecting rod 45 as the center of the circle, and then wipes the surface of the reflector body 22 to wipe off the dust. The cover 31 can be opened and closed repeatedly to clean the dust and dirt on the reflector body 22, and when the cover 31 is closed, the cleaning block 41 can be opened and closed repeatedly to clean the dust and dirt on the reflector body 22. When the sub-block 31 slides to the open state, the cleaning block 41 just rotates 180 degrees with the connecting rod 45 as the center. At this time, the reflector body 22 will not be blocked by the cleaning block 41, and will not affect the use of the autofocus laser 5. The staff will replace the cleaning block 41 every time the autofocus laser 5 is used. The outer circle of the cleaning block 41 is the mounting ring, and the cleaning sponge is installed inside the mounting ring. The cleaning block 41 is mounted on the connecting rod 45 through the mounting ring clip. When replacing, it can be directly removed and replaced. The dust and dirt on the surface of the reflector body 22 can be effectively cleaned through the above operation. The structure is simple, the operation is easy, and the work efficiency is improved.

[0034] Embodiment 2

[0035] The clamping assembly 34 includes a telescopic slot 341, which is opened at the center of one side of the bottom of the housing 21 away from the slide slot 33. A telescopic rod 342 is fixedly installed at the center of the top of the slot cavity of the telescopic slot 341, and a trapezoidal clamping block 344 is fixedly installed at the telescopic end of the telescopic rod 342. A spring 343 is sleeved on the surface of the telescopic rod 342, and the top end of the spring 343 is fixedly welded to the top of the telescopic slot 341, and the bottom end of the spring 343 is fixedly welded to the top of the trapezoidal clamping block 344.

[0036] A plurality of slots 345 matching the trapezoidal blocks 344 are evenly and equidistantly formed in the center of one side of the top of the cover 31 away from the slide bar 32;

[0037] When the cover 31 is slid, the trapezoidal block 344 is stuck in the slot 345, and the cover 31 will not slide easily. The worker needs to push the cover 31 with a large force. At this time, the inclined surface of the trapezoidal block 344 is subjected to force. Through the decomposition of the force, it can be known that the trapezoidal block 344 will be subjected to a force in the direction of the telescopic slot 341, so that the trapezoidal block 344 compresses the spring 343 and shrinks back into the telescopic slot 341. When the cover 31 slides the trapezoidal block 344 to the slot 345 at the far left, the cover 31 is stopped from being pushed. The trapezoidal block 344 rebounds into the slot 345 under the action of the spring 343. At this time, the cover 31 is just opened. In this process, the rack 44 The gear 2 43 is driven to rotate, and the gear 2 43 drives the gear 1 42 to rotate, which indirectly drives the cleaning block 41 to rotate with the connecting rod 45 as the center, thereby wiping the surface of the reflector body 22 to wipe off the dust. The cover 31 can be opened and closed repeatedly to clean the dust and dirt on the reflector body 22, and when the cover 31 slides to the open state, the cleaning block 41 just rotates 180 degrees with the connecting rod 45 as the center. At this time, the reflector body 22 will not be blocked by the cleaning block 41, and the use of the autofocus laser 5 will not be affected. The dust and dirt on the surface of the reflector body 22 can be effectively cleaned, and the structure is simple and easy to operate.
