[0075] By arranging a friction pressing feeding mechanism and a high-frequency vibration friction pressing mechanism, when in use, the friction pressing feeding mechanism is used to realize automatic friction pressing feeding and unloading of lenses and plastic boxes by the high-frequency vibration friction pressing mechanism, and the high-frequency vibration friction pressing mechanism is used to realize vibration friction pressing of lenses and plastic boxes, without the need for manual bonding with glue, thereby solving the problems of low production efficiency, loose bonding and substandard environmental protection in the existing production of cosmetic packaging materials, in which lenses and plastic boxes are bonded manually with glue.

[0076] Working principle: In the process of producing cosmetic packaging materials, the control program of the friction welding controller 2 is first set, and then the screw reduction drive motor 405 is controlled by the friction welding controller 2 to work, and the screw reduction drive motor 405 drives the driving screw 404 to rotate, and the driving screw 404 drives the driving block 403 and the guide plate 4021 to move on the guide seat 4 and the support guide rail 402, and drives the support arm 406 and the vibration friction welding machine 412 to move, so that the amplitude rod 4121 on the vibration friction welding is concentric with the friction welding tooling 306.

[0077] Then the friction crimping controller 2 controls the crimping drive motor 408 and the reducer 407 to drive the crimping drive screw 409 to rotate, drive the connecting seat 411 and the vibration friction welding machine 412 to move downward, adjust the distance between the vibration friction welding machine 412 and the friction welding tooling 306, and ensure that after the amplitude change rod 4121 in the vibration friction welding machine 412 is extended, the stroke is sufficient to perform vibration friction welding on the lens and the plastic box.

[0078] Then, according to the diameter of the plastic box and the lens, the friction contact area formed by the multiple friction blocks 425 is adjusted and controlled. During the adjustment process, the friction crimping controller 2 automatically controls the reduction motor 423 to work, and the reduction motor 423 drives the adjustment shaft 421 to rotate, and the adjustment shaft 421 drives the driving gear 422 to rotate, and the driving gear 422 drives the variable pitch adjustment gear 415 to rotate.

[0080] After the friction block 425 is adjusted, the friction press joint controller 2 automatically loads the plastic box onto the friction welding tooling 306 through the loading device, and then loads the lens onto the plastic box, and the feeding reduction drive motor 301 works, and the output end of the feeding reduction drive motor 301 drives the feeding drive shaft 302 to rotate, and the feeding drive shaft 302 drives the feeding tray 303 to rotate, and the rotation angle of the feeding tray 303 is positioned through the cooperation of the sensing block 307 and the proximity sensor 305. After the feeding tray 303 feeds the lens and the plastic box to the bottom of the vibration friction welding machine 412, the friction press joint controller 2 controls the vibration friction welding machine 412 to work, and the amplitude change rod 4121 in the vibration friction welding machine 412 extends to drive the fixed plate 413, the strengthening connection arc plate 424 and the friction block 425 to move and contact the lens (in actual friction During the welding process, in order to protect the glossiness of the metal lens, the friction block 425 is in contact with the surface of the lens through the protective cotton and vibrates and rubs. The protective cotton is rolled up on the unwinding wheel in strips. During friction crimping, the protective cotton strip is rolled up by the winding wheel after use. It is disposable. A new section of cotton strip is used to contact the lens and the friction block 425 for each friction crimping). Then, the friction block 425 is driven to vibrate at high frequency through the amplitude variable rod 4121 to firmly weld the lens and the plastic box. Then, the amplitude variable rod 4121 contracts to separate the friction block 425 from the lens. Then, the friction crimping controller 2 controls the feeding deceleration drive motor 301 to work, driving the feeding plate 303 to rotate, and the welded lens and plastic box are rotated away from the bottom of the vibration friction welding machine 412, and the new unwelded lens and plastic box are rotated to the bottom of the vibration friction welding machine 412.

[0081] When welding larger lenses and plastic boxes, in order to ensure that the welding is firm, while the amplitude change rod 4121 drives the friction block 425 for vibration welding, the friction crimping controller 2 controls the reduction motor 423 to work, and the reduction motor 423 drives the adjustment shaft 421 to rotate, and the adjustment shaft 421 drives the driving gear 422 to rotate, and the driving gear 422 drives the variable pitch adjustment gear 415 to rotate counterclockwise, drives the variable pitch adjustment arc groove 416 to move, pushes the drive pin shaft 420 toward the axis of the fixed disk 413, drives the adjustment column 419 to shrink into the plug-in groove 417, and drives the friction block 425 to shrink toward the axis of the fixed disk 413, thereby increasing the area of ​​friction welding.
