Description

Technical Field

[0001] This utility model relates to the field of marking machine technology, specifically to a laser marking machine. Background Technology

[0002] Laser marking machines use a laser beam to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thus engraving intricate patterns, trademarks, and text. During laser marking, a certain amount of dust is generated. This dust rises and diffuses, causing severe air pollution in the workshop. Some dust adheres to the guide rails and lead screws on the base plate, affecting the smooth movement of the panel carrying the product. When the dust accumulates to a certain thickness, the motor driving the panel experiences increased resistance and overheating, potentially leading to resonance. This causes the product to vibrate on the panel, resulting in misalignment during the marking process, affecting both the marking quality and aesthetics. Utility Model Content

[0022] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] like Figure 1-6As shown, a laser marking machine includes a worktable 1, a movable marking device 2, a base plate 3, a panel 4, a drive mechanism, and a negative pressure device. The worktable 1 has a through-groove 101 at its upper end. The base plate 3 is fixedly connected to the groove 101. Multiple crossbeams are provided between the two inner sides of the groove 101, and the base plate 3 is fixedly connected to the crossbeams, elevating the base plate 3 for easier operation and cleaning. The drive mechanism is fixedly connected to the rear end of the base plate 3, and its output end is connected to the panel 4. The panel 4 can slide longitudinally onto the base plate 3. The drive mechanism can be directly driven by a motor 7, or a reduction gearbox can be added to improve transmission efficiency and make the movement of the panel 4 more flexible. The movable marking device 2 spans the groove 101 and is fixedly connected to the upper end of the worktable 1. The lower end of the movable marking device 2 has a laser head 203 that can slide laterally within the groove 101. The laser head 203 is located above the panel 4 and can perform laser operations on the product. The movable marking device 2 includes a control box 201. The transverse track motion mechanism 202 and the laser head 203, along with cables, control components, etc., are integrated into the control box 201. The transverse track motion mechanism 202 drives the laser head 203 to move laterally within the groove 101 and perform laser operations, all of which are existing technologies. The negative pressure device is fixedly connected to the rear end of the workbench 1. The panel 4 is provided with multiple dust suction holes 406, and the rear end of the panel 4 is provided with a dust suction pipe 404. The dust suction pipe 404 is connected to the multiple dust suction holes 406, and the dust suction pipe 404 is connected to the negative pressure device through an air pipe. The smoke and dust generated during laser operations enter the dust suction holes 406 downwards and are collected by the negative pressure device, preventing the smoke and dust from spreading upwards and causing serious air pollution in the workshop. It also prevents the smoke and dust from adhering to the base plate 3, ensuring the smooth movement of the panel 4 and preventing the drive mechanism from being blocked by fine particles brought by the smoke and dust, which could cause overheating, resonance, etc. It also ensures that the panel 4 moves smoothly and that the products on the panel 4 do not shift, thereby ensuring accurate marking positions.

[0024] In the above embodiment, the upper end of the base plate 3 is provided with a guide rail 301, and the lower end of the panel 4 is provided with a guide groove 401. The guide rail 301 and the guide groove 401 are slidably connected to provide guidance for the movement of the panel 4. The upper end of the base plate 3 is provided with two supports 5, one in front and one behind, and a lead screw 6 is rotatably connected between the two supports 5. The output end of the drive mechanism is connected to the rear end of the lead screw 6. The lower end of the panel 4 is provided with a threaded hole 402, which is connected to the lead screw 6. The position movement of the panel 4 is more precise, and the guide rail 301 and the guide groove 401 can provide auxiliary support for the threaded connection between the lead screw 6 and the panel 4, avoiding deformation of the lead screw 6 due to long-term load. The upper end of the base plate 3 is provided with a position sensor 17 facing the panel 4, which can detect the position of the panel 4, facilitating the control of the laser head 203. At the same time, the position sensor 17 can also be electrically connected to the control box 201, etc., to obtain the position information of the panel 4 and provide trigger conditions for the marking program. The upper end of the panel 4 is provided with a rectangular recessed area 407. Multiple recessed areas 407 are arranged in a matrix on the upper end of the panel 4. The recessed areas 407 provide sufficient space for the products to be processed, and make it easier for the products to slide in. After the product processing is completed, the panel 4 will quickly move and reset. At this time, the product, located within the recessed area 407, is less likely to slide out, preventing the product from falling outside the panel 4. The upper end of the panel 4 is provided with an L-shaped baffle 8. The two inner sides of the baffle 8 are flush with the inner sides of the recessed areas 407. Multiple baffles 8 are provided, corresponding to multiple recessed areas 407. The baffles provide positioning for the products to be processed, ensuring consistency in processing position and effect for each product, improving product quality and aesthetics. The baffle 8 has two inner sides with adsorption holes 801, and the panel 4 has an adsorption tube 405 at the rear end. The adsorption tube 405 is connected to the adsorption holes 801 and to the negative pressure device via an air pipe. When the product to be processed is placed in the recessed area 407 and close to the baffle 8, it is adsorbed by the adsorption force provided by the negative pressure device and adhered to the inside of the baffle 8, thereby achieving rapid positioning and correction, which is beneficial to the installation efficiency of the product to be processed. Since the adsorption tube 405 is connected to the adsorption holes 801 of multiple baffles 8 at the same time, the adsorption force provided by the negative pressure device reaches its maximum and the adsorption effect is best when all the products to be processed are attached to the inside of their corresponding baffles 8. In order to achieve the best adsorption effect of the baffle 8 and the dust collection effect of the panel 4, a first negative pressure device 9 is connected to the dust collection pipe 404, and a second negative pressure device 10 is connected to the adsorption tube 405. The air outlet of the first negative pressure device 9 is connected to an external dust removal device to capture fine particles brought by smoke and dust, ensuring a clean and hygienic workshop.

[0025] Due to the high manufacturing difficulty of setting up gas channels inside panel 4, this device uses a combination of A and B plates for panel 4 manufacturing, as described above. A plate is the upper surface panel 4, and B plate is the lower surface panel 4. The bottom of A plate and the top of B plate are milled to create grooves connecting the suction pipe 404 and the adsorption pipe 405, respectively. After A plate and B plate are fixed together with screws, the wiring between the two sets of grooves does not overlap, ensuring that each function is achieved independently. The combination of A and B plates reduces manufacturing difficulty. Furthermore, after long-term use, dust and particles will accumulate in the gas channels, allowing A and B plates to be disassembled for cleaning and reuse, ensuring the smooth operation of the suction and adsorption functions.

[0026] In addition, this device also includes a vortex mechanism 14 and a cloth strip 12. The front end of the workbench 1 has two support plates 11, one on the left and one on the right, with a rotating shaft rotatably connected between them. The cloth strip 12 is wound around the rotating shaft. The vortex mechanism 14 is installed on the outside of the two support plates 11 and is connected to the rotating shaft. A hook 403 is provided on the front side of the lower end of the panel 4. One end of the cloth strip 12 has a hanging ring 13, allowing the cloth strip 12 to be hung on the hook 403 via the hanging ring 13. The vortex mechanism 14 operates by using a vortex... The spiral spring enables automatic winding. The retraction of the strip is achieved through the energy storage and release of the spiral spring, essentially functioning as a spring mechanism, which is existing technology. As the panel 4 slides backward, the guide rail 301 and lead screw 6 on the base plate 3 gradually emerge. The panel 4 pulls out the rolled fabric strip 12, covering the base plate 3 and shielding the guide rail 301 and lead screw 6. This effectively prevents some of the escaping dust from falling onto the guide rail 301 and lead screw 6, ensuring their cleanliness and thus ensuring smooth movement of the panel 4. Two supports 15 are located at the front ends of both sides of the base plate 3. A roller 16 is rotatably connected between the two supports 15. The fabric strip 12 can roll and connect with the roller 16. The roller 16 prevents the fabric strip 12 from contacting and rubbing against the base plate 3, providing a transition and guidance for the fabric strip 12, ensuring it is not easily worn and can be used for a long time.

[0027] Description of the working principle of this utility model:

[0028] The power bank casing is a three-dimensional rectangle. Before inserting the battery, it is processed using a laser marking machine to engrave the brand name and pattern onto the casing. The second negative pressure device 10 is activated, and the unprocessed casings are placed sequentially in the recessed areas 407 of the panel 4 and pushed against the inside of the baffle strips 8. At this point, under the suction force provided by the second negative pressure device 10, the unprocessed casings are adsorbed onto the inside of the baffle strips 8 where the adsorption holes 801 are located, achieving initial correction and positioning. After all the unprocessed casings are placed sequentially into their corresponding recessed areas 407 and against the baffle strips 8, the adsorption holes 801 of multiple baffle strips 8 are all aligned with their corresponding casings, and the suction force provided by the second negative pressure device 10 reaches its maximum, resulting in the best adsorption effect. At this point, further correction and positioning are achieved. After starting the motor 7 and the first negative pressure device 9, the lead screw 6 rotates and drives the panel 4 to slide from front to back. At the same time, the control box 201 controls the laser head 203 to move laterally at the lower end of the transverse track motion mechanism 202, and performs laser marking through the laser head 203. While the laser operation is in progress, the dust generated from processing the power bank shell goes directly to the first negative pressure device 9 through the dust suction hole 406, and is then captured by the external dust removal device. As the panel 4 continues to slide backward, the guide rail 301 and the lead screw 6 on the base plate 3, which are covered by the panel 4, are... As the power bank casing is gradually exposed, the hook 403 pulls out the cloth strip 12 wound on the rotating shaft via the hanging ring 13, covering the guide rail 301 and the lead screw 6. This prevents dust escaping during processing from falling onto the guide rail 301 and the lead screw 6. After the power bank casing is processed, as the panel 4 slides forward and resets, the pulled-out cloth strip 12 is gradually retracted under the action of the vortex mechanism 14. The entire process effectively prevents the track and lead screw 6 from being exposed, keeping them clean and hygienic, thus ensuring the smoothness and stability of the panel 4's forward and backward sliding. During the panel 4 reset process, the first negative pressure device 9 closes when the panel 4 triggers the position sensor 17, and the second negative pressure device 10 closes after the panel 4 is fully reset, allowing the processed power bank casing to be removed. The power bank's size parameters, brand name, and pattern used in the laser operation can be input through the control panel 184 on the workbench 1, or data can be exchanged with an external computer device for easy process adjustment.
