Description

Technical Field

[0001] This utility model relates to the field of marking equipment technology, and in particular to a casing marking device. Background Technology

[0002] A housing is a protective outer shell enclosing the core components of various devices or instruments. Common materials include plastics and metal alloys, and it is widely used in many fields such as automobiles. In the housing production process, laser marking equipment is used to mark text, numbers, or graphics on its surface. This equipment uses a laser beam to cause physicochemical changes in the surface material of the housing, forming a mark to achieve product traceability and brand identification. In existing technologies, when laser marking equipment is in operation, the surface material of the housing is burned by the laser, producing fumes. Harmful substances and particulate matter contained in the fumes accumulate in the working area, leading to a decline in workshop air quality and dust pollution. Long-term exposure to such an environment not only increases the risk of respiratory diseases for workers but also contaminates other precision instruments in the workshop. Simultaneously, corrosive components in the fumes adhere to critical components such as optical lenses and guide rails of the laser marking equipment. With increasing use, this gradually erodes the surface of these components, reducing the equipment's operational accuracy and stability, shortening its lifespan, and increasing maintenance and replacement costs. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a casing marking device that can remove the fumes generated during the marking process, thereby improving the working environment, protecting personnel health, and extending the service life of the equipment.

[0004] The casing marking equipment according to an embodiment of the present invention includes a frame; a smoke removal component disposed on the frame, the smoke removal component having a light-passing hole, a vacuum chamber being disposed inside the smoke removal component, and a plurality of suction holes being disposed on the inner wall of the light-passing hole, all of the plurality of suction holes communicating with the vacuum chamber; a laser marking device disposed on the frame, the laser emitted by the laser marking device being able to pass through the light-passing hole and act on the casing; and a suction device used to create a negative pressure in the vacuum chamber so that smoke can pass through the plurality of suction holes and enter the vacuum chamber.

[0005] It has at least the following beneficial effects: When laser marking is required on a machine casing, place the casing in the corresponding position on the frame. After the equipment is started, the laser beam emitted by the laser marking device passes through the light-passing holes on the smoke extraction unit and acts on the surface of the casing placed in the corresponding position on the frame. The laser energy causes a physicochemical change in the material on the casing surface, thereby completing the marking and forming text, numbers, or graphics on the casing surface. During the laser marking process, the suction device operates simultaneously. The suction device creates a negative pressure in the vacuum chamber inside the smoke extraction unit. When smoke is generated during the marking process, the smoke is drawn into the vacuum chamber through multiple suction holes on the inner wall of the light-passing holes under the suction effect of the negative pressure, achieving real-time collection and treatment of the smoke. The light-passing holes on the smoke extraction unit are precisely matched with the laser beam path, and the multiple suction holes are distributed around the laser beam, allowing multiple suction holes to perform all-round, close-range suction of the smoke source, preventing the smoke from spreading into the working environment. Moreover, the negative pressure suction force is uniform and stable, and will not interfere with the laser marking accuracy. The fume extractor in this laser marking machine effectively removes fumes generated during the marking process, preventing the accumulation of harmful substances and particulate matter in the fume within the workshop. This improves the working environment, reduces the risk of respiratory illnesses for workers, and minimizes contamination of other precision instruments in the workshop. Furthermore, the fume extractor prevents corrosive components in the fume from adhering to critical parts such as the optical lenses and guide rails of the laser marking device, reducing erosion and wear on these components. This improves the accuracy and stability of the laser marking machine, extends its service life, and lowers maintenance and replacement costs.

They are only for the convenience of describing this utility model and simplifying the description, and do not 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.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] refer to Figures 1 to 3 This utility model discloses a casing marking device, including a frame 600, a smoke removal component 100, a suction device 300, and a laser marking device 200.

[0021] A smoke removal component 100 is mounted on a frame 600. A light-passing hole 130 is formed on the smoke removal component 100, allowing the laser emitted by the laser marking device 200 to pass through. Multiple suction holes 110 are evenly distributed on the inner wall of the light-passing hole 130. In this embodiment of the invention, a vacuum cavity is formed inside the smoke removal component 100; that is, the smoke removal component 100 is a shell component, and the multiple suction holes 110 are all connected to the vacuum cavity.

[0022] A suction device 300 is mounted on the frame 600. The suction device 300 creates a negative pressure in the multiple suction holes 110 on the inner wall of the light-passing aperture 130, allowing the suction holes 110 to draw gas from the inner wall region of the light-passing aperture 130. In this embodiment, the suction device 300 includes a vacuum generator, a suction pipe 310, and a filter. The output end of the vacuum generator is connected to the vacuum chamber within the smoke removal component 100 via the suction pipe 310. The filter is mounted on the suction pipe 310 and is used to filter impurities. Under the action of the vacuum generator, a negative pressure is created between the vacuum chamber and the multiple suction holes 110, causing gas carrying impurities in the inner wall region of the light-passing aperture 130 to pass through the multiple suction holes 110 and be drawn into the vacuum chamber. Under the suction action of the vacuum generator, the gas in the vacuum chamber is continuously drawn in, allowing the gas carrying impurities in the vacuum chamber to enter the suction pipe 310. When the gas carrying impurities flows within the suction pipe 310, a filter installed on the suction pipe 310 filters the gas, trapping and collecting the impurities. The filtered clean gas then continues through the suction pipe 310 into the vacuum generator, and is finally discharged from the vacuum generator. The impurities here mainly consist of smoke particles and harmful substances generated during the laser marking process. In this embodiment of the invention, the vacuum generator can be a common vacuum pump.

[0023] The laser marking device 200 is mounted on the frame 600. The laser emitted by the laser marking device 200 can pass through the light aperture 130 and act on the housing 10, so that information such as text, numbers or graphics can be formed on the surface of the housing 10.

[0024] Understandably, when laser marking is required on the housing 10 to be marked, the housing 10 is placed in the corresponding position on the frame 600. After the equipment is started, the laser beam emitted by the laser marking device 200 passes through the light-passing hole 130 on the smoke removal component 100 and acts on the surface of the housing 10 placed in the corresponding position on the frame 600. The laser energy causes a physicochemical change in the surface material of the housing 10, thereby completing the marking and forming information such as text, numbers, or graphics on the surface of the housing 10. During the laser marking process, the suction device 300 operates simultaneously. The suction device 300 creates a negative pressure in the vacuum chamber inside the smoke removal component 100. When the housing 10 generates smoke during the marking process, the smoke will be attracted by the negative pressure and enter the vacuum chamber through multiple suction holes 110 on the inner wall of the light-passing hole 130, realizing real-time collection and treatment of the smoke. The light-passing aperture 130 on the smoke removal component 100 is precisely matched with the laser beam path, and multiple suction holes 110 are distributed around the laser beam. This allows the multiple suction holes 110 to perform all-round, close-range suction of the smoke source, preventing the smoke from spreading into the working environment. Furthermore, the negative pressure suction force is uniform and stable, without interfering with the laser marking accuracy. The smoke removal component 100 in this casing marking equipment effectively removes the smoke generated during the marking process, preventing the accumulation of harmful substances and particulate matter contained in the smoke in the workshop, improving the working environment, reducing the risk of respiratory diseases among workers, and minimizing contamination of other precision instruments in the workshop. On the other hand, the smoke removal component 100 prevents corrosive components in the smoke from adhering to key components such as the optical lenses and guide rails of the laser marking device 200, reducing erosion and wear on the equipment components, improving the accuracy and stability of the casing marking equipment, extending its service life, and reducing maintenance and replacement costs.

[0025] refer to Figure 3The inner wall of the light-passing aperture 130 includes multiple inclined surfaces 120. The area enclosed by the multiple inclined surfaces 120 gradually expands in the direction away from the laser marking device 200, and multiple suction holes 110 are provided on each of the multiple inclined surfaces 120. It can be understood that the area enclosed by the multiple inclined surfaces 120 gradually expands in the direction away from the laser marking device 200, and multiple suction holes 110 are provided on each of the multiple inclined surfaces 120. When the laser beam emitted by the laser marking device 200 passes through the light-passing aperture 130 and acts on the surface of the housing 10, the marking smoke will diffuse from the surface of the housing 10 to the surrounding areas. The gradually expanding structure of the area enclosed by the multiple inclined surfaces 120 allows the multiple inclined surfaces 120 to guide the diffused smoke, making it easier for the smoke to flow towards the inner wall of the light-passing aperture 130. Meanwhile, the suction holes 110 distributed on the multiple inclined surfaces 120, under the negative pressure of the vacuum chamber, can form an adsorption force on the smoke from different angles. The inclination angle of the inclined surfaces 120 is adapted to the diffusion path of the smoke to reduce the resistance during the smoke flow process, so that the smoke can enter the vacuum chamber more smoothly through the suction holes 110, avoiding the smoke from being trapped or escaping in the light passage 130. On the other hand, the area enclosed by the multiple inclined surfaces 120 gradually expands in the direction away from the laser marking device 200. This design allows the suction holes 110 to be closer to the core area where the smoke is generated, increasing the amount of smoke suction per unit time, further enhancing the smoke removal efficiency, and will not obstruct or interfere with the transmission of the laser beam. Thus, while ensuring the marking accuracy, it solves the smoke pollution problem more efficiently, which in turn helps to extend the service life of the equipment and improve the working environment.

[0026] refer to Figure 2 and Figure 3The suction hole 110 is an oblong shape, with its length parallel to the width of the inclined plane 120. This oblong shape, compared to other shapes like circular holes, provides a longer opening length for the same area, increasing the effective adsorption range of smoke entering the suction hole 110. As smoke diffuses along the inclined plane 120, the longer opening of the suction hole 110 covers a larger area along the smoke diffusion path, increasing the probability of smoke capture. Furthermore, the parallelism of the length of the suction hole 110 to the width of the inclined plane 120 allows it to conform to the extension direction of the inclined plane 120, ensuring its full distribution across the width of the plane. This avoids localized adsorption blind spots caused by improper orientation of the suction hole 110, ensuring that smoke at different widths of the inclined plane 120 is uniformly adsorbed. Furthermore, the waist-shaped suction hole 110 ensures a large suction area while its smooth opening edge reduces resistance to smoke flow, allowing the smoke generated during marking to enter the vacuum chamber more smoothly through the suction hole 110, further enhancing smoke removal efficiency. In this embodiment of the invention, the inner wall of the light-passing hole 130 includes four inclined surfaces 120, which are located at the top, bottom, left, and right positions, respectively.

[0027] refer to Figure 2The laser marking device 200 includes a laser mechanism 210, a vision module 220, and a multi-axis drive mechanism 230. The multi-axis drive mechanism 230 is used to drive the laser mechanism 210 and the smoke removal component 100 to move in the front-back, left-right, and up-down directions. In this embodiment of the invention, the vision module 220 of the laser marking device 200 includes a camera 221 and an image processing unit. The laser marking device 200 also includes a control system. After the device is started and the housing 10 is positioned in the corresponding position on the frame 600, the vision module 220 first scans the surface of the housing 10 through the camera 221 to capture the actual contour, position, and surface feature information of the housing 10. Then, the camera 221 transmits the scanned image data to the image processing unit. The image processing unit analyzes and processes the data and transmits it to the control system. The control system compares the data with the preset marking pattern and position information to generate compensation data for correcting the marking path, in order to address possible installation deviations or shape errors of the housing 10. Subsequently, the multi-axis drive mechanism 230 starts working according to the generated marking path compensation data. It can drive the laser mechanism 210 and the smoke removal component 100 to adjust their distance from the housing 10 in the front-back direction, adjust their lateral position in the left-right direction, and adjust their height in the up-down direction. During the adjustment process, the laser incident angle of the laser mechanism 210 is adjusted in real time to ensure that the laser beam can act on the surface of the housing 10 at the optimal angle. Especially for the curved housing 10, the laser energy distribution in different areas of the curved surface can be ensured through multi-directional position adjustment and angle correction. When the laser mechanism 210 is adjusted to the preset marking position and at a suitable incident angle, the laser mechanism 210 emits a laser beam, which passes through the light-passing hole 130 of the smoke removal component 100 and acts on the surface of the housing 10. At the same time, the multi-axis drive mechanism 230 drives the laser mechanism 210 to move according to the compensated marking path to complete the marking of text, numbers, or graphics. Throughout the process, the suction device 300 works synchronously to remove the smoke generated by marking through the smoke removal component 100.

[0028] In this embodiment of the invention, the laser mechanism 210 and the smoke removal component 100 move synchronously to ensure that the laser beam emitted by the laser mechanism 210 always passes through the light-passing hole 130 on the smoke removal component 100 before acting on the housing 10. Specifically, the smoke removal component 100 is mounted on the laser mechanism 210.

[0029] In this embodiment of the invention, the multi-axis drive mechanism 230 can be a common multi-axis manipulator. The output end of the multi-axis manipulator is connected to the laser mechanism 210 and the smoke removal component 100 to drive the laser mechanism 210 to move in the front-back, left-right, and up-down directions. The multi-axis drive mechanism 230 can also be a common combination structure of multiple linear drive modules, typically including linear modules arranged along the X-axis (left-right direction), Y-axis (front-back direction), and Z-axis (up-down direction). Each linear module consists of a drive motor, a lead screw or synchronous belt, and a slider. When the drive motor drives the lead screw to rotate or the synchronous belt to move, the slider drives the laser mechanism 210 to move along the corresponding axis. Through the independent control and coordination of the three linear modules, the precise positioning of the laser mechanism 210 is achieved. In this embodiment of the invention, the laser mechanism 210 for emitting the laser beam, the camera 221 and image processing unit in the vision module 220, and the laser mechanism 210 and control system in the laser marking device 200 are all common configurations in the field of laser marking technology, and will not be further elaborated here.

[0030] In one embodiment of this utility model, the output end of the multi-axis drive mechanism 230 is connected to the vision module 220, and the multi-axis drive mechanism 230 can drive the vision module 220 to move in the front-back, left-right, and up-down directions. If the housing 10 is large in size, or if marking is required on the surface of the housing 10 in multiple positions and with complex paths, the vision module 220 needs to move with the laser mechanism 210 in order to capture local images of the current marking position in real time and achieve large-area scanning.

[0031] refer to Figure 2 and Figure 4 The vision module 220 includes a camera 221 and two lamps 222. The camera 221 is mounted on the frame 600, and the two lamps 222 are located on the upper and lower sides of the camera 221, respectively. The camera 221 is fixed to the frame 600 and aimed at the surface of the housing 10 to be scanned. The two lamps 222 are mounted on the upper and lower sides of the camera 221, and the illumination direction of the lamps 222 is adapted to the shooting direction of the camera 221, so that the two lamps 222 can jointly illuminate the area to be scanned on the surface of the housing 10. The lamps 222 can provide sufficient and uniform illumination for the camera 221, reducing the loss of image details on the surface of the housing 10 due to insufficient light or uneven brightness, avoiding interference from shadows on the outline and feature recognition of the housing 10, and ensuring that the camera 221 can clearly capture the actual position, shape, and surface information of the housing 10, providing a reliable image basis for subsequently generating accurate marking path compensation data.

[0032] In this embodiment of the invention, two lamps 222 are rotatably connected to the frame 600, allowing the illumination angles of the two lamps 222 to be adjusted. Since the housing 10 has various shapes, including flat, curved, or textured surfaces, different housing structures have different light requirements during scanning. For example, for a flat housing 10, the lamps 222 can be adjusted to vertical or small-angle illumination to ensure uniform light coverage. For curved or textured housings 10, adjusting the illumination angle by rotating the lamps 222 can reduce shadows caused by structural obstruction, preventing localized overly dark or bright light. Furthermore, housings 10 made of different materials (such as plastic or metal alloys) have varying reflectivities; adjusting the lamp angle optimizes light reflection and reduces interference from reflections on the camera 221. The adjustable illumination angles of the two lamps 222 allow the vision module 220 to adapt to the scanning needs of different types and structures of housings 10, improving the applicability of the vision module 220.

[0033] In one embodiment of this utility model, the vision module 220 further includes two motors and two mounting bases. Each of the two lamps 222 has a rotating shaft, and both motors are mounted on the frame 600. The two mounting bases are respectively fixed to the frame 600 and located on the upper and lower sides of the camera 221. Each of the two lamps 222 is rotatably connected to the two mounting bases via rotating shafts. One end of the rotating shaft on each lamp 222 extends to the outside of the mounting base, and the output ends of the two motors are respectively connected to the two rotating shafts. When it is necessary to adjust the angle of the lamps 222, the two motors drive the two rotating shafts to rotate, thereby causing the lamps 222 to rotate around the rotating shafts to adjust the illumination angle.

[0034] refer to Figure 1 and Figure 5The casing marking equipment also includes a conveying device 400 and a positioning fixture 500. A marking station is provided on the frame 600. The positioning fixture 500 is used to position the casing 10. The conveying device 400 is located on the frame 600. The smoke removal component 100 is located between the conveying device 400 and the laser marking device 200. The conveying device 400 is used to convey the positioning fixture 500 so that the positioning fixture 500 and the casing 10 can move to the marking station. The laser marking device 200 is used to laser mark the casing 10 on the positioning fixture 500 at the marking station. It can be understood that the upstream equipment moves the casing 10 to be marked into the positioning fixture 500. The positioning fixture 500 uses its own structure to accurately position the casing 10, preventing displacement of the casing 10 during conveying and marking. Subsequently, the conveying device 400 starts, driving the positioning fixture 500, which holds the casing 10, to move along a preset path. When the conveying device 400 transports the positioning fixture 500 and the housing 10 to the marking station, the conveying device 400 stops operating, and the positioning fixture 500 remains stable at the marking station. Immediately afterwards, the laser marking device 200 starts, and the laser beam emitted by the laser marking device 200 passes through the light-passing hole 130 on the smoke removal component 100, precisely acting on the surface of the housing 10 on the positioning fixture 500. Simultaneously, the suction device 300 works concurrently, sucking away the smoke generated during marking through the suction hole 110 and the vacuum chamber of the smoke removal component 100. After marking is completed, the conveying device 400 starts again, transporting the positioning fixture 500 carrying the marked housing 10 from the marking station to the downstream docking position, where the next process equipment removes the marked housing 10 from the positioning fixture 500. Afterwards, the conveying device 400 continues to drive the empty positioning fixture 500 to move in a cycle, and then conveys it to the upstream docking position to wait for the new marking housing 10, thereby realizing the automated continuous production of marking on the housing 10.

[0035] refer to Figure 5The conveying device 400 includes a lifting mechanism and two linear drive mechanisms 410, both mounted on the frame 600. The lifting mechanism is located between the two linear drive mechanisms 410. Both linear drive mechanisms 410 support and convey the positioning fixture 500, enabling the positioning fixture 500 and the housing 10 to move to the marking station. The lifting mechanism drives the positioning fixture 500 at the marking station to rise. It is understood that the positioning fixture 500 is conveyed synchronously with the two linear drive mechanisms 410. When the positioning fixture 500 carrying the housing 10 to be marked is conveyed to the corresponding position at the marking station, the two linear drive mechanisms 410 stop conveying. Subsequently, the lifting mechanism located between the two linear drive mechanisms 410 is activated, extending upwards and lifting the positioning fixture 500, causing the positioning fixture 500 to detach from the support of the linear drive mechanisms 410 and rise to the preset marking height. After the positioning fixture 500 stabilizes, the laser marking device 200 marks the housing 10 on the positioning fixture 500, while the suction device 300 removes smoke through the smoke removal component 100. After marking is completed, the lifting mechanism retracts, placing the positioning fixture 500 back onto the two linear drive mechanisms 410. The linear drive mechanisms 410 continue to operate, transporting the positioning fixture 500 carrying the marked housing 10 downstream. Simultaneously, a new positioning fixture 500 is transported to the marking station, repeating the above process. The two linear drive mechanisms 410 ensure stable transport of the positioning fixture 500, guaranteeing its accurate arrival at the marking station. The lifting mechanism can raise the positioning fixture 500, so that the housing 10, laser marking device 200, and smoke removal component 100 are in a better relative position. On the one hand, it can reduce the impact of vibration of linear drive mechanism 410 during operation on marking accuracy. On the other hand, it can make the housing 10 closer to the light hole 130 of smoke removal component 100, enhance the smoke extraction effect, and at the same time, it is convenient to flexibly adjust the marking height according to the housing 10 of different thicknesses or specifications, and improve the adaptability of the equipment to diverse housings 10.

[0036] In this embodiment of the invention, the linear drive mechanism 410 is a belt conveyor mechanism, and the lifting mechanism is a push-plate cylinder lifting mechanism. The belt conveyor mechanism includes a drive wheel, a driven wheel, a conveyor belt, and a conveyor motor. The conveyor motor drives the drive wheel to rotate, and the drive wheel is linked with the driven wheel through the conveyor belt. The surface of the conveyor belt contacts the bottom of the positioning fixture 500, and the positioning fixture 500 moves synchronously with the conveyor belt by means of friction, thereby realizing the stable conveying of the positioning fixture 500 on the frame 600 and ensuring that the positioning fixture 500 carrying the housing 10 is accurately transferred to the corresponding area of ​​the marking station. The lifting mechanism adopts a push-plate cylinder type lifting mechanism. The cylinder body of the push-plate cylinder is fixed on the frame 600, and a horizontal push plate is connected to the top of the piston rod. When the positioning fixture 500 is sent to the marking station by the belt conveyor mechanism, the piston rod of the push-plate cylinder extends upward, and the push plate rises synchronously and contacts the bottom of the positioning fixture 500. As the piston rod continues to extend, the push plate lifts the positioning fixture 500 off the conveyor belt, causing it to detach from the conveyor belt and rise to the preset marking height. After marking is completed, the piston rod of the push-plate cylinder retracts, and the push plate drives the positioning fixture 500 to descend until the positioning fixture 500 is placed back on the conveyor belt. Then, the belt conveyor mechanism starts and transports the positioning fixture 500 to the next position. The push plate is also equipped with a positioning post, and the bottom of the positioning fixture 500 has a positioning hole. The positioning post can be inserted into the positioning hole, so that the push plate can accurately and stably support the positioning fixture 500, further preventing the positioning fixture 500 from shifting during the lifting process.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
