Content of the Utility Model
[0003] The utility model provides a laser marking machine, which can reduce the overflow of dust and smoke during the marking process and maintain the surface cleanliness of the working board.
[0004] To this end, the present application provides a laser marking machine, and the technical scheme adopted is as follows:
[0005] It includes a chassis body. The upper surface of the chassis body has a workbench, and a marking opening is provided on the workbench. The marking opening is a rectangular opening with four sides, and a rotating door leaf is rotatably connected to each side through a rotating shaft.

Specific implementation manner
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.
[0025] As Figures 1 - 6 shown, a laser marking machine includes a chassis main body 100. The upper surface of the chassis main body 100 has a workbench 10. A marking port 1 is opened on the workbench 10. The marking port 1 is a rectangular port with four sides. A rotating door leaf 12 is rotatably connected to each side through a rotating shaft 11. Among them, two relatively arranged rotating door leaves 12 can jointly act to close the marking port 1. Each rotating shaft 11 is arranged along the length direction of the corresponding side and is driven to rotate by a driving device; a pushing mechanism is provided inside the chassis main body 100, and a working plate 3 is fixed on the pushing mechanism. The working plate 3 can be pushed out and brought back to the marking port 1 by the pushing mechanism.
[0026] The laser marking machine further includes a moving component 4. The moving component 4 is fixed on the workbench 10 surface. A laser head 5 is fixed above the moving component 4. The laser head 5 includes a laser and a lens. A control panel 104 is fixed on the workbench 10. A control system and a heat dissipation device are also fixed inside the chassis main body 100.
[0027] When the marking machine is working, first turn on the device power supply. The control system controls the driving device to open the rotating door leaf 12, and controls the pushing mechanism to push the working plate 3 into the space enclosed by the rotating door leaf 12. The height can be adjusted according to different workpiece types. Then, place the item to be marked on the working plate 3. The control system is connected to the laser head 5 and sends the required marking information to the laser. The laser focuses the laser beam on a high-precision lens, and the lens focuses the laser beam on the position to be marked. Through the irradiation of the laser, the required pattern or text is engraved on the surface of the object. After the marking is completed, the device automatically stops the marking work, removes the marked item, and presses the specified button on the control panel 104. The pushing mechanism brings the working plate 3 back inside the chassis body 100.
[0028] Among them, a movement channel 101 is fixed inside the chassis body 100. The movement channel 101 is vertically arranged and extends from the bottom of the chassis body 100 to the marking port 1. The pushing mechanism and the workbench 10 move up and down in the movement channel 101. A dust removal fan 102 is fixed on the side wall of the movement channel 101, and the dust removal fan 102 is located above the side wall of the movement channel 101. A dust suction device 103 is fixed at the bottom of the movement channel 101, and the dust suction device 103 is communicated with a dust collection box.
[0029] Thus, after the pushing mechanism brings the working plate 3 back inside the chassis body 100, the dust and smoke generated by marking will be brought into the movement channel 101. The control system controls the dust removal fan 102 and the dust suction device 103 to work together, blows the dust and the like brought back to the inside of the movement channel 101 from the surface of the working plate 3 and sucks them into the dust collection box. After the cleaning is completed, the dust removal fan 102 and the dust suction device 103 are turned off, and finally the power supply is turned off to complete the marking operation. The dust collection box needs to be cleaned regularly later.
[0030] By setting the rotating door leaf 12, during the marking process, the rotating door leaf 12 can enclose the middle working plate 3, thereby preventing the smoke and dust generated during the marking process from escaping to the surroundings and affecting the working environment and the physical health of the staff.
[0031] By setting the pushing mechanism, when the working plate 3 does not need to work, it is brought inside the chassis body 100 and the rotating door leaf 12 is closed, thereby ensuring that the working plate 3 will not be polluted by dust in the environment when it is not working. At the same time, the soot generated after the working plate 3 is marked will also be brought inside the chassis body 100 and cleaned by the dust removal fan 102, preventing the dust and powder remaining on the surface of the working plate 3 from polluting the workpiece to be marked or affecting the marking accuracy when used again.
[0032] Such as Figure 6As shown in the figure, the driving device includes a first gear 111 sleeved and fixed on the rotating shaft 11, a second gear 112 meshing with the first gear 111, and a driving motor 113 for driving the second gear 112 to rotate. The control system drives the driving motor 113 to rotate, driving the second gear 112 to rotate synchronously, so that the first gear 111 meshing with it drives the gear shaft to rotate synchronously, and the gear shaft further drives the rotating door leaf 12 to rotate. The rotating door leaf 12 can rotate at different angles. That is, during the marking operation, the four rotating door leaves 12 all open upward to enclose a marking space. After the marking is completed, the rotating door leaves 12 retract. Among them, a pair of opposite rotating door leaves 12 rotate 180° downward and fit against the side wall of the movement channel 101 inside the chassis body 100 to prevent interference with the movement of the working plate 3 and the pushing mechanism. The other pair of rotating door leaves 12 rotate 90° to close the marking opening 1.
[0033] As Figure 4 and Figure 5 shown in the figure, the pushing mechanism includes a pushing base 21 fixed to the bottom of the chassis body 100. A pushing cylinder 22 is fixed above the pushing base 21. A supporting plate 23 is fixed to the telescopic end of the pushing cylinder 22. The working plate 3 is fixed on the supporting plate 23. Thus, the control system controls the pushing cylinder 22 to push and retract the working plate 3. The pushing cylinder 22 is first fixed to the supporting plate 23, and the supporting plate 23 is connected to the working plate 3, which can ensure the horizontality and stable connection of the working plate 3 and is convenient for replacing the working plate 3.
[0034] Furthermore, in order to ensure the levelness of the working plate 3, a fixing plate 25 is fixed to the fixed end of the pushing cylinder 22. Through holes are provided on the fixing plate 25. The fixing plate 25 and the supporting plate 23 are connected by guide posts 26. One end of the guide post 26 is fixed to the supporting plate 23, and the other end passes through the through hole on the fixing plate 25 and is vertically arranged. That is, the guide posts 26 ensure the stable operation and always keep the working plate 3 horizontal.
[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
