Description

Technical Field

[0002] The working principle of laser marking equipment is to focus a laser beam with extremely high energy density on the surface of the object to be marked. Through burning and etching, the material on the surface is vaporized, and by controlling the effective displacement of the laser beam, patterns or text are precisely etched. A laser marking machine is a laser device that uses a laser beam to make permanent marks on the surface of various materials.

However, the existing marking equipment cannot efficiently achieve precise alignment or spacing control between the logo on the cup body and the logo on the cup lid when the cup lid already has a marked logo. This makes it difficult to meet the market's stringent requirements for consistency of markings on high-end products.

[0004] Therefore, a laser marking device for thermos cups is proposed. Utility Model Content

[0042] Working principle: Feeding: The conveyor belt of the feeding unit 2 transports the thermos cups under the drive of the drive motor. When the cups reach the discharge port, the pneumatic gripper 1015 of the feeding and transfer mechanism 4 clamps the thermos cups. The transfer unit in the feeding and transfer mechanism 4 transfers the thermos cups to the position adjustment mechanism 7 between the cup mold 704 and the mold base 703 through the first motor 1002, the first lead screw 1003 and the synchronous belt 1004. The detection plate 705 initially supports the thermos cups.

[0043] Position recognition and adjustment: The electric push rod 709 drives the detection plate 705 down to the threaded part of the thermos cup body and lid. The grating reader 7084 and grating ruler 7082 provide real-time feedback on the displacement, achieving precise alignment of the thermos cup's angle and height. The controller controls the hollow rotating platform 702 to rotate the mold base 703, thereby driving the thermos cup to rotate. The Y-axis electric linear module 602 and X-axis electric linear module 603 of the vision recognition unit 6 adjust the position of the vision positioning camera 604, collect the logo image on the lid, and transmit it to the controller. Then, based on the current position of the logo on the lid, the controller controls the hollow rotating platform 702 to rotate the thermos cup by a certain angle and then stops.

[0044] Marking: The material feeding and transfer mechanism 9 clamps the aligned thermos cup and transfers it to the second support seat 510 of the lifting mechanism 5; the laser marking machine 8 starts marking, and the third servo motor 505 drives the third lifting screw 506 to move the thermos cup on the second support seat 510 up and down to complete the marking.

[0045] Material unloading: After marking is completed, the material unloading and transfer mechanism 9 transfers the thermos cup to the first support seat 302 of the material unloading unit 3. The rodless cylinder 301 drives the first support seat 302 to move to the unloading point to complete the unloading. The equipment cyclically executes the above process to achieve continuous production.
