Description

Technical Field

[0001] This utility model relates to the technical field of laser marking machines, and in particular to a protection mechanism for laser marking machines. Background Technology

[0002] Laser marking equipment, also known as laser inkjet printer or laser marking machine, is divided into two types: scribing type and dot matrix type. The working principle is to focus a laser with extremely high energy density on the surface of the object to be marked, and vaporize the material on its surface through burning and etching. By controlling the effective displacement of the laser beam, patterns or text are precisely etched.

[0003] For example, Chinese utility model patent CN202021159483.7 describes an installation protection device for a laser marking machine. This device uses a protective cover to ensure the cable to be marked is located inside, improving marking safety. The cover also prevents workers' hands and other body parts from coming into contact with the infrared laser rays emitted by the laser marking machine during the marking process, thus preventing skin burns. However, this protective cover is fixedly connected to the workbench. When the position and height of the laser marking machine are adjusted, the cover cannot be used with the machine after the position is changed, resulting in low flexibility and practicality. Utility Model Content

[0004] The purpose of this invention is to provide a protection mechanism for a laser marking machine to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A protective mechanism for a laser marking machine includes a marking assembly. The marking assembly comprises: an adjustment component disposed on the top of a worktable; a laser marking machine body disposed on one side of the adjustment component; and a protective assembly disposed on the top of the worktable and located below the laser marking machine body. The protective assembly comprises: a first protective housing disposed on the top of the worktable; a second protective housing penetrating the top of the first protective housing and located below the lens of the laser marking machine body; an outer shell disposed on the outer side of the first protective housing; a rotating rod penetrating the outer shell and rotatably connected to it; a gear disposed at one end of the rotating rod and located inside the outer shell; a through groove on the outer wall of the first protective housing that engages with the gear; a toothed groove symmetrically disposed on the outer wall of the second protective housing and meshing with the gear; a first slider disposed at the bottom of the first protective housing; and a first sliding groove on the top of the worktable that engages with the first slider; and a dust extraction assembly disposed on the top of the worktable and penetrating the side wall of the first protective housing.

[0007] Optionally, the outer side of the rotating rod is provided with a thread, and a threaded sleeve is provided on the thread and sleeved on the outer side of the rotating rod.

[0008] Optionally, a compression plate is provided on one side of the threaded sleeve and is located on the outer side wall of the housing.

[0009] Optionally, an anti-slip pad is provided between the extrusion plate and the outer wall of the housing.

[0010] Optionally, a support block is provided on the outer side of the first protective housing, and a rod is provided on the support block and passes through the support block. The top of the first slide groove has symmetrical slots that cooperate with the rod.

[0011] Optionally, a spring is provided on the outer side of the insertion rod and located at the bottom of the support block.

[0012] Optionally, the outer side of the second protective housing has a second slider symmetrically arranged, and the inner sidewall of the first protective housing is provided with a second sliding groove that cooperates with the second slider.

[0013] Optionally, the bottom of the second protective housing is provided with a limiting plate that cooperates with the gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The first protective housing is moved back and forth by the first slider and the first groove, so that the second protective housing is located directly below the lens of the laser marking machine body. Then, the rotating rod is rotated, and the rotating rod drives the gear to rotate. The rotating gear is connected to the second protective housing through the meshing of the tooth groove, which pushes the second protective housing to rise and fall on the first protective housing. This makes the height of the first protective housing plus the second protective housing adapt to the adjusted height of the laser marking machine body lens. Thus, the protective component can adapt to the adjusted laser marking machine body, increasing the flexibility and practicality of the laser marking machine protection mechanism.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Given that in the current technology, the protective cover is fixedly connected to the worktable, when the adjustment structure adjusts the position and height of the laser marking machine, the protective cover cannot be adapted to the laser marking machine after the position is adjusted, resulting in low flexibility and practicality of the protective cover.

[0027] like Figures 1-4 As shown, this utility model embodiment provides a protective mechanism for a laser marking machine, including a marking component 1. The marking component 1 includes: an adjustment component 12 disposed on the top of a worktable 11; a laser marking machine body 13 disposed on one side of the adjustment component 12; and a protective component 2 disposed on the top of the worktable 11 and located below the laser marking machine body 13. The protective component 2 includes: a first protective housing 21 disposed on the top of the worktable 11; a second protective housing 211 penetrating through the top of the first protective housing 21 and located below the lens of the laser marking machine body 13; and an outer shell 22 disposed on the first protective housing 21. The outer side; the rotating rod 23 passes through the outer shell 22 and is rotatably connected to the outer shell 22; the gear 24 is disposed at one end of the rotating rod 23 and is located inside the outer shell 22; the outer side wall of the first protective shell 21 is provided with a through groove 25 that engages with the gear 24; the tooth groove 241 is symmetrically disposed on the outer side wall of the second protective shell 211 and is meshed with the gear 24; the first slider 26 is disposed at the bottom of the first protective shell 21, and the top of the workbench 11 is provided with a first sliding groove 261 that engages with the first slider 26; the dust collection assembly 14 is disposed at the top of the workbench 11 and passes through the side wall of the first protective shell 21.

[0028] In use, the cable to be marked is passed through the through hole of the first protective housing 21 and wound up. Simultaneously, the laser marking machine body 13 is activated to mark the surface of the cable. The first and second protective housings 211 prevent the operator's hands and other body parts from coming into contact with the infrared laser rays emitted by the laser marking machine, thus preventing skin burns. The dust extraction component 14 absorbs the smoke and dust generated during laser marking and removes it from the interior of the first and second protective housings 211, preventing smoke and dust from covering the lens of the laser marking machine body 13. When the position and height of the laser marking machine body 13 are adjusted, the marking process continues according to the adjusted position and height. The first protective housing 21 is moved back and forth by the first slider 26 and the first groove 261, so that the second protective housing 211 is located directly below the lens of the laser marking machine body 13. Then, the rotating rod 23 is rotated, and the rotating rod 23 drives the gear 24 to rotate. The rotating gear 24 is connected to the second protective housing 211 through the meshing of the tooth groove 241, which pushes the second protective housing 211 to rise and fall on the first protective housing 21. Thus, the height of the first protective housing 21 plus the second protective housing 211 is adapted to the adjusted height of the lens of the laser marking machine body 13. This allows the protective component 2 to adapt to the adjusted laser marking machine body 13, increasing the flexibility and practicality of the laser marking machine protection mechanism.

[0029] Specifically, the model of the laser marking machine body 13 is FLM-20 / 30. Its working principle is as follows: It adopts a galvanometer laser system: the laser beam is deflected by a high-speed galvanometer motor, and a focusing lens is used to form a tiny spot (about 0.01-0.1mm) on the surface of the workpiece. The precise marking is achieved by controlling the movement trajectory of the spot through a computer.

[0030] Specifically, the dust collection component 14 is the same as the suction component in the prior art (CN202021159483.7), including a suction fan connected inside the first protective housing 21 and a collection box disposed at the end of the suction fan away from the first protective housing 21.

[0031] Furthermore, the outer side of the rotating rod 23 is provided with a thread 27, and a threaded sleeve 271 is provided on the thread 27 and sleeved on the outer side of the rotating rod 23. When the rotating rod 23 is rotated to push the second protective housing 211 to rise and fall, the threaded sleeve 271 is rotated. The rotating threaded sleeve 271 moves and squeezes towards the outer wall of the outer shell 22 through the thread 27, thereby squeezing and locking the rotating rod 23, increasing the stability of the second protective housing 211 after rising and falling.

[0032] Furthermore, a pressing plate 272 is provided on one side of the threaded sleeve 271 and is located on the outer wall of the outer shell 22, which increases the area of the threaded sleeve 271 pressing the outer wall of the outer shell 22 and improves the stability of pressing and locking the rotating rod 23.

[0033] Furthermore, an anti-slip pad 273 is provided between the extrusion plate 272 and the outer wall of the outer shell 22, which increases the anti-slip properties of the extrusion plate 272 and the outer wall of the outer shell 22.

[0034] Furthermore, a support block 29 is provided on the outer side of the first protective housing 21, and an insertion rod 291 is provided on the support block 29 and passes through the support block 29. The top of the first sliding groove 261 has symmetrical slots 292 that cooperate with the insertion rod 291. When the first protective housing 21 is pushed to move back and forth, the insertion rod 291 is pushed to move downward and insert into the corresponding slot 292 at the top of the first sliding groove 261 to lock and fix the first protective housing 21.

[0035] Furthermore, a spring 293 is provided on the outer side of the insertion rod 291 and is located at the bottom of the support block 29. The elasticity of the spring 293 pushes the insertion rod 291 into the slot 292, ensuring the stability of the insertion rod 291 into the slot 292.

[0036] Furthermore, the outer side of the second protective housing 211 is symmetrically provided with a second slider 28, and the inner sidewall of the first protective housing 21 is provided with a second sliding groove 281 that matches the second slider 28, so that the second protective housing 211 and the first protective housing 21 are slidably connected, which increases the stability of the gear 24 pushing the second protective housing 211 to rise and fall.

[0037] Furthermore, a limiting plate 242 with a cooperating gear 24 is provided at the bottom of the second protective housing 211 to limit the second protective housing 211 and prevent the second protective housing 211 from detaching from the inside of the first protective housing 21 when it rises.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
