The holographic anti-counterfeiting label is a high-security anti-counterfeiting label based on laser holographic technology. Its core technical principle and dynamic optical characteristics make it the mainstream choice in the field of commodity anti-counterfeiting. By using the principle of laser interference to record the three-dimensional information of an object, a three-dimensional holographic image is generated, which can reproduce the original three-dimensional effect under a specific light source.

[0061] A controller 5 is fixed to the front side of the cabinet body 12. The controller 5 is electrically connected to the first motor 22, the push rod motor 31, the tension sensor 27, the second motor 411, and the vision camera 423.

[0062] Working principle:

[0063] After the detection board 211 and the detection component 311 are installed on the device, the detection program is started through the controller 5. First, the push rod motor 31 is controlled to push the detection component 311 downward. When the bottom of the detection component 311 contacts the top of the detection board 211, the bottom of the limit frame 310 contacts the top of the moving plate 24 at the same time, limiting the U-shaped frame 1 34, so that the detection component 311 stops moving downward. When the push rod motor 31 continues to extend the inner rod, it will compress the spring 3 312 with the stationary U-shaped frame 1 34, causing the vertical rod 32 and the heater 33 to move downward. The heater 33 moves downward to press on the top of the detection component 311 and heat it, hot stamping the anti-counterfeiting label on the detection component 311 onto the top of the detection board 211. Then, the push rod motor 31 retracts the inner rod, causing the heater 33 to move upward, and the spring 3 312 resets. After resetting, it drives the U-shaped frame 1 34 to move upward, and the U-shaped frame 1 34 drives the detection component 311 to move upward. When moving upward, the anti-counterfeiting label separates from the bottom of the detection component 311, and a pulling force is generated during separation. The pulling force acts on the detection board 211, and the detection board 211 pulls the tensile force sensor 27 through the suction cup 28. The tensile force sensor 27 obtains the tensile force data and sends it to the controller 5. The controller 5 obtains the adhesion between the anti-counterfeiting label material and the substrate. The higher the adhesion of the anti-counterfeiting label material, the higher the fitting force with the detection board 211, the better the anti-counterfeiting effect, reducing the possibility of damage to the anti-counterfeiting label caused by external factors such as friction, and detecting the wear and scratch resistance of the anti-counterfeiting label;

[0064] After the anti-counterfeiting label is hot stamping, start motor 1 22 to drive screw rod 23 to rotate, so that the moving plate 24 drives the moving stage 25 and the detection plate 211 to move below the multi-angle imaging optical vision detection mechanism 4. Start the vision camera 423 and the annular light source 424. The annular light source 424 is a matte lamp. While illuminating the anti-counterfeiting label, it avoids the strong reflection of light in the mirror panel 419 from affecting the vision camera 423 to obtain images. Then control motor 2 411 to drive gear 1 412 to rotate, so that gear 3 42 drives the reciprocating screw rod 41 to rotate, and the L-shaped moving plate 45 pushes the second annular plate 44 downward. The downward movement of the second annular plate 44 drives the annular turntable 46 and multiple mirror panels 419 below to move downward. During the downward movement, gear 2 47 is always engaged with the long gear 48. After moving downward a certain distance, the rubber pad under the first annular plate 422 contacts the top of the detection plate 211, enclosing the anti-counterfeiting label inside. The anti-counterfeiting label is located between multiple mirror panels 419. After the first annular plate 422 contacts the detection plate 211, it cannot move downward. The second annular plate 44 continues to drive the annular turntable 46 to press the mounting plate 418. After the mounting plate 418 is pressed, the bottom rotates around the connection point with the mounting frame 420, and the top connecting block 417 pushes the moving block 416 to slide on the third guide rod 414 and compress the first spring 415. The connecting block 417 rotates around the connection point with the moving block 416, causing the mounting plate 418 and the mirror panel 419 to gradually tilt. It should be noted that the image observed of the holographic anti-counterfeiting label will present a dynamic three-dimensional pattern when the tilt angle changes. While gear 1 412 rotates, it drives gear 4 410 to rotate, so that the rotating shaft 49 drives the long gear 48 to rotate. The long gear 48 drives gear 2 47 and the annular turntable 46 to rotate. The rotation of the annular turntable 46 drives multiple mounting plates 418 and mirror panels 419 to rotate. The mounting plate 418 drives the mounting frame 420 and the rotating ring 421 to rotate. During the rotation process, the mirror panel 419 continuously tilts. The vision camera 423 obtains the dynamic anti-counterfeiting label image reflected by the mirror panel 419, and judges the integrity of the anti-counterfeiting label image and the clarity of the image color based on this dynamic image. After obtaining complete data by rotating a certain angle, the data is transmitted to the controller 5 for evaluation.
