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

[0025] like Figure 1 As shown:

[0026] A high-speed laser marking device comprises a laser marking body 1, a chassis cover 11 hinged to the surface of the laser marking body 1, and a marking head 2 arranged inside the laser marking body 1.

[0027] like Figures 1-6 As shown:

[0028] In combination with the above content, in order to effectively remove pollutants such as particulate matter and harmful gases, a purification component 3 is also included installed on the back side of the laser marking body 1. The purification component 3 includes an air inlet pipe 31 fixed on the back side of the laser marking body 1, a purification box 32 fixed on the surface of the air inlet pipe 31, and filter plates 1 37 and 38 arranged inside the purification box 32.

[0029] In an optional embodiment, a fan 33 is fixed inside the air inlet pipe 31, a bevel gear set 34 is fixed to the output shaft end of the fan 33, a transmission rod 35 is coaxially fixed inside the bevel gear of the bevel gear set 34, a push-pull groove adapted to the filter plate 1 37 is opened inside the purification box 32, and the filter plate 1 37 is inserted into the interior of the purification box 32, the filter plate 2 38 is located on the rear side of the filter plate 1 37, the filter hole inside the filter plate 2 38 is smaller than the filter hole inside the filter plate 1 37, and the filter plate 2 38 is fixed to the interior of the purification box 32, one end of the transmission rod 35 passes through the interior of the purification box 32, and extends to the outside of the purification box 32, and is connected to the synchronous belt 33 arranged on the outside of the purification box 32 6 is fixedly connected, and rotating rollers 39 are symmetrically connected to the upper and lower sides of the interior of the purification box 32, and the pulley of the synchronous belt 36 is coaxially fixedly connected to one group of rotating rollers 39, and a rotating belt 310 is connected between the two groups of rotating rollers 39, and a plurality of cleaning plates 311 arranged at equal distances are fixed on the surface of the rotating belt 310, and the surface of the cleaning plate 311 is attached to the surface of the filter plate 2 38, and an air outlet pipe 312 is fixed on the side of the purification box 32 away from the air inlet pipe 31, and a sewage trough is provided inside the purification box 32 near the bottom of the filter plate 2 38, and a collecting box 313 is provided below the sewage trough, and the collecting box 313 is fixed to the back surface of the laser marking body 1.

[0030] In this embodiment: after the fixation of the marking object is completed, the laser marking body 1 can be sealed and closed by flipping the chassis cover 11. At the same time, the tempered glass on the surface of the chassis cover 11 is convenient for observing the internal processing of the equipment. Then the equipment is started, and the marking head 2 is turned on. By starting the transverse motor 41, the transverse screw rod 42 can be driven to drive the transverse seat 43 to move transversely inside the laser marking body 1, and then the longitudinal screw rod 45 and the marking head 2 can be driven to move transversely synchronously. By starting the longitudinal motor 44 to drive the longitudinal screw rod 45 to rotate between the two sets of transverse seats 43, the marking head 2 can be driven to move longitudinally inside the laser marking body 1, thereby flexibly adjusting the marking position of the marking head 2 and being able to adjust according to needs.

[0031] During the marking operation, the fan 33 is started, and the fan 33 cooperates with the air inlet pipe 31 to absorb and discharge the exhaust gas and smoke generated during the laser marking process inside the laser marking body 1. The absorbed exhaust gas and smoke will be filtered and purified by the filter plate 1 37 and the filter plate 2 38 and finally discharged from the air outlet pipe 312. The filtering and purification by the filter plate 1 37 and the filter plate 2 38 can effectively remove particulate matter, harmful gases and other pollutants therein, and can effectively prevent them from being directly discharged into the atmosphere, thereby reducing the adverse effects on air quality and protecting the ecological environment. The timely treatment of exhaust gas and smoke can significantly reduce the risk of operators being exposed to harmful environments, reduce the pollution of smoke to the working area, improve the air quality of the working environment, protect the health of the operator, eliminate potential health risks, provide the operator with a more comfortable and healthy working condition, and ensure the purity of the laser beam. The treatment of exhaust gas and smoke can prevent them from affecting the transmission and focusing of the laser, thereby ensuring the accuracy and quality of laser marking and improving the production efficiency and quality of the product.

[0032] During this period, as the fan 33 runs, it can drive the bevel gear group 34 to rotate inside the air inlet pipe 31, and then drive the transmission rod 35 to rotate inside the air inlet pipe 31. Then, under the transmission action of the synchronous belt 36, it can drive the rotating roller 39 to rotate inside the purification box 32, and then drive the rotating belt 310 to rotate, which can drive multiple groups of cleaning plates 311 to slide and clean along the surface of the filter plate 2 38 in turn, thereby timely removing the smoke and dust waste on the surface of the filter plate 2 38, preventing the filter holes from being blocked, and ensuring that the filter plate 2 38 always maintains good air permeability and filtering effect, thereby continuously and effectively filtering the exhaust gas and smoke generated during the laser marking process, reducing the corrosion and wear of the filter plate 2 38 by the smoke and dust waste, reducing the replacement frequency of the filter plate 2 38, reducing the equipment maintenance cost, and further reducing pollution to the environment. The cleaned smoke and dust waste will fall through the sewage trough opened inside the purification box 32 and be collected in the collection box 313.

[0033] Going further:

[0034] In combination with the above content, in order to firmly fix the marked object in a specific position, it also includes a fixing component 4 installed inside the laser marking body 1, and the fixing component 4 includes a marking table 46 fixed inside the laser marking body 1, a bidirectional screw rod 48 rotatably connected to the inside of the marking table 46, and a fixing plate 49 threadedly connected to both sides of the surface of the bidirectional screw rod 48.

[0035] In an optional embodiment: the interior of the laser marking machine body 1 is symmetrically screwed with transverse motors 41 on both sides, the output ends of the two sets of transverse motors 41 are fixed with transverse screws 42, and the transverse screws 42 are rotatably connected to the interior of the laser marking machine body 1, the surface of the transverse screw 42 is threadedly connected to the transverse seat 43, and the two sets of transverse seats 43 are rotatably connected with a longitudinal screw 45, and the surface of one set of transverse seats 43 is screwed with a longitudinal motor 44, the output end of the longitudinal motor 44 and one end of the longitudinal screw 45 are fixedly connected, the marking head 2 is threadedly connected to the surface of the longitudinal screw 45 through the moving seat, and one side of the surface of the marking table 46 is screwed with a fixed motor 47, and the fixed motor 4 The output end of 7 is fixedly connected to one end of a bidirectional screw rod 48, a movable groove adapted to a fixed plate 49 is provided inside the marking platform 46, and a pressure sensor 410 is fixed on the opposite side of the two groups of fixed plates 49, a worm gear 411 is fixed to the middle part of the surface of the bidirectional screw rod 48, a bidirectional screw rod 2 412 is coaxially fixed inside the worm of the worm gear 411, and the bidirectional screw rod 2 412 is rotatably connected to the inside of the marking platform 46, and threaded push blocks 413 are symmetrically threaded on both sides of the surface of the bidirectional screw rod 2 412, and a fixed plate 2 415 is symmetrically provided on the opposite side of the two groups of threaded push blocks 413, and a spring 414 is fixed between the fixed plate 2 415 and the threaded push block 413.

[0036] In this embodiment: the object to be marked is placed on the marking table 46, and then the fixed motor 47 is started. The fixed motor 47 drives the bidirectional screw rod 1 48 to rotate inside the marking table 46, thereby driving the fixed plates 1 49 on both sides of the surface of the bidirectional screw rod 1 48 to slide in the movable grooves opened inside the marking table 46, and driving the pressure sensor 410 to approach the surface of the marking object. When the pressure sensor 410 is attached to the surface of the marking object, the piezoelectric signal inside it will change. When the piezoelectric signal reaches the threshold value, the fixed motor 47 will automatically turn off, and the fixed plate 1 49 can be squeezed against the surface of the marking object to achieve preliminary fixation of the marking object. During this period, the rotation of the bidirectional screw rod 1 48 can drive the worm gear 411 to rotate synchronously, thereby driving the bidirectional screw rod 2 412 on the marking table 46. The inner part of the screw rod 413 is rotated, thereby driving the threaded push block 413 to move along the surface of the bidirectional screw rod 412, and then, with the cooperation of the spring 414, it can drive the fixed plate 415 toward the surface of the marking object. When the fixed plate 415 is against the surface of the marking object, under the action of the spring 414, a buffer can be made between the fixed plate 415 and the marking object, and the surface of the marking object can be squeezed and fixed again, thereby ensuring that the marking object will not move or shake during the laser marking process, and the marking object can be firmly fixed in a specific position to achieve precise positioning, improve marking accuracy, and prevent the marking object from accidentally moving or falling during the marking process, thereby improving the marking stability. A stable marking object can reduce the marking error caused by position change and obtain a more accurate marking effect.

[0037] The working principle and use process of the present invention are as follows: when in use, first place the object to be marked on the marking table 46, then start the fixed motor 47, and the fixed motor 47 drives the bidirectional screw rod 48 to rotate inside the marking table 46, thereby driving the fixed plates 49 on both sides of the surface of the bidirectional screw rod 48 to slide in the movable grooves opened inside the marking table 46, and driving the pressure sensor 410 to approach the surface of the marking object. When the pressure sensor 410 is attached to the surface of the marking object, the piezoelectric signal inside it will change. When the piezoelectric signal reaches the threshold value, the fixed motor 47 will automatically turn off, and the fixed plate 49 can be squeezed against the surface of the marking object to achieve preliminary fixation of the marking object. During this period, the rotation of the bidirectional screw rod 48 can drive the worm gear 411 to rotate synchronously, thereby driving the bidirectional screw rod 48 to rotate synchronously. 12 rotates inside the marking table 46, thereby driving the threaded push block 413 to move along the surface of the bidirectional screw rod 2 412, and then, with the cooperation of the spring 414, it can drive the fixed plate 2 415 toward the surface of the marking object. When the fixed plate 2 415 is against the surface of the marking object, under the action of the spring 414, it can make way for a buffer between the fixed plate 2 415 and the marking object, and the surface of the marking object can be squeezed and fixed again, thereby ensuring that the marking object will not move or shake during the laser marking process, and the marking object can be firmly fixed in a specific position to achieve precise positioning, improve marking accuracy, and prevent the marking object from accidentally moving or falling during the marking process, thereby improving the stability of marking. A stable marking object can reduce the marking error caused by position change and obtain a more accurate marking effect.

[0038] After the marking object is fixed, the laser marking body 1 can be sealed and closed by flipping the chassis cover 11. At the same time, the tempered glass on the surface of the chassis cover 11 is convenient for observing the internal processing of the equipment. Then start the equipment and turn on the marking head 2. By starting the transverse motor 41, the transverse screw rod 42 can be driven to drive the transverse seat 43 to move transversely inside the laser marking body 1, and then drive the longitudinal screw rod 45 and the marking head 2 to move transversely synchronously. By starting the longitudinal motor 44 to drive the longitudinal screw rod 45 to rotate between the two sets of transverse seats 43, the marking head 2 can be driven to move longitudinally inside the laser marking body 1, thereby flexibly adjusting the marking position of the marking head 2 and being able to adjust as needed.

[0039] During the marking operation, the fan 33 is started, and the fan 33 cooperates with the air inlet pipe 31 to absorb and discharge the exhaust gas and smoke generated during the laser marking process inside the laser marking body 1. The absorbed exhaust gas and smoke will be filtered and purified by the filter plate 1 37 and the filter plate 2 38 and finally discharged from the air outlet pipe 312. The filtering and purification by the filter plate 1 37 and the filter plate 2 38 can effectively remove particulate matter, harmful gases and other pollutants therein, and can effectively prevent them from being directly discharged into the atmosphere, thereby reducing the adverse effects on air quality and protecting the ecological environment. The timely treatment of exhaust gas and smoke can significantly reduce the risk of operators being exposed to harmful environments, reduce the pollution of smoke to the working area, improve the air quality of the working environment, protect the health of the operator, eliminate potential health risks, provide the operator with a more comfortable and healthy working condition, and ensure the purity of the laser beam. The treatment of exhaust gas and smoke can prevent them from affecting the transmission and focusing of the laser, thereby ensuring the accuracy and quality of laser marking and improving the production efficiency and quality of the product.

[0040] During this period, as the fan 33 runs, it can drive the bevel gear group 34 to rotate inside the air inlet pipe 31, and then drive the transmission rod 35 to rotate inside the air inlet pipe 31. Then, under the transmission action of the synchronous belt 36, it can drive the rotating roller 39 to rotate inside the purification box 32, and then drive the rotating belt 310 to rotate, which can drive multiple groups of cleaning plates 311 to slide and clean along the surface of the filter plate 2 38 in turn, thereby timely removing the smoke and dust waste on the surface of the filter plate 2 38, preventing the filter holes from being blocked, and ensuring that the filter plate 2 38 always maintains good air permeability and filtering effect, thereby continuously and effectively filtering the exhaust gas and smoke generated during the laser marking process, reducing the corrosion and wear of the filter plate 2 38 by the smoke and dust waste, reducing the replacement frequency of the filter plate 2 38, reducing the equipment maintenance cost, and further reducing pollution to the environment. The cleaned smoke and dust waste will fall through the sewage trough opened inside the purification box 32 and be collected in the collection box 313.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
