Description

Technical Field

[0001] This invention relates to the field of wristband manufacturing technology, specifically to a production line and control method for anti-counterfeiting wristbands. Background Technology

[0002] Anti-counterfeiting wristbands, as one-time identification tags, are widely used in fields such as medical care and large-scale event management. Ensuring both anti-counterfeiting features and production efficiency are crucial in the production process. Wristband production typically involves steps such as coding, film cutting, and snap fastener installation. These steps are often completed using multiple independent machines. Coding is usually done by an inkjet printer, film cutting requires a specialized film cutting machine, and snap fastener installation requires manual or semi-automatic fastener machines. Manual transfer and connection between these machines are necessary. Therefore, this multi-machine serial production method leads to a cumbersome production process, increased labor and time costs, low production efficiency, and a higher risk of errors, affecting product consistency and anti-counterfeiting effectiveness.

[0003] Therefore, it is necessary to design an integrated production line and its control method to realize the production of anti-counterfeiting wristbands. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a production line for anti-counterfeiting wristbands, including a frame. Several conveying rollers are provided on the upper end of the frame extending along the forward conveying direction. A feeding roller, a coding device, an infrared drying device, a visual inspection device, a marking device, a film cutting device, a first buckle-making machine, a second buckle-making machine, and a receiving roller are sequentially arranged on the upper surface of the frame along the forward conveying direction. The feeding roller is connected to the frame via a bracket. The coding device includes a first linear guide rail, a first slide table, a coating ink cartridge, a coating pump, and a coating head. The first linear guide rail is fixedly mounted on the frame, and the first slide table is mounted on the first linear guide rail. The first slide table moves along the first linear guide rail, and a coating ink cartridge is mounted on the first slide table for coating. The ink cartridge has a spray pump at its lower end, and a spray head at its lower end. The visual inspection device includes a second linear guide rail, a second slide table, and an inspection camera. The second linear guide rail is fixedly mounted on the frame, and the second slide table moves along the second linear guide rail. The inspection camera is mounted on the second slide table. The first buttoning machine includes a support base, a feeding device, and a stamping mechanism. The support base is fixedly mounted on the frame and has the feeding device and stamping mechanism. The stamping mechanism includes an upper punch seat, a lower punch seat, and a punch. The upper punch seat is located at the upper end of the support base, and the punch is detachably mounted on the upper punch seat. The lower punch seat is located at the upper end of the support base. The second buttoning machine has the same structure as the first buttoning machine.

[0005] The frame is equipped with a PLC controller, which is electrically connected to the inkjet printer, infrared drying device, visual inspection device, marking device, film cutting device, first buttoning machine, and second buttoning machine.

[0006] The first and second linear guides are perpendicular to the forward conveying direction.

[0007] The infrared drying device includes a box and infrared light strips. The box is horizontally mounted on the frame, and several infrared light strips are installed on the top of the box.

[0008] The inspection camera is a CCD industrial camera, and the inspection camera is connected to an image processing system.

[0009] The marking device includes a connecting seat, an electric telescopic rod, and a stamp head. The connecting seat is fixedly mounted on the frame, and the electric telescopic rod is mounted on the connecting seat. The lower end of the electric telescopic rod is equipped with a stamp head.

[0010] The die-cutting device includes a base, a die-cutting roller, and a bottom roller. The base is fixedly mounted on the frame, the die-cutting roller is mounted on the base, and the bottom roller is mounted below the die-cutting roller.

[0011] A control method for a production line of anti-counterfeiting wristbands includes the following steps: S1: Feeding, the anti-counterfeiting wristband substrate is placed on a feeding roller and moves along the forward conveying direction via the feeding roller and conveyor rollers; S2: Coding, the coding device sprays a preset anti-counterfeiting code onto the surface of the wristband substrate; S3: Drying, the coated wristband substrate enters an infrared drying device to dry and cure the anti-counterfeiting code; S4: Visual inspection, the dried wristband substrate moves to a visual inspection device, the inspection camera captures the anti-counterfeiting code image and transmits it to an image processing system for recognition and comparison analysis to determine whether the coding quality is up to standard. S5: Marking. If the visual inspection device determines that the inkjet printing quality is unqualified, the marking device controls the stamp head to mark the unqualified product; S6: Die-cutting. The wristband substrate continues to advance to the die-cutting device, where it is die-cut into a single wristband shape; S7: Buckling. The die-cut wristbands sequentially enter the first buckling machine and the second buckling machine. The feeding devices of the first and second buckling machines respectively send the female buckle and the female buckle to the stamping position for stamping, and install the female buckle and the female buckle in the preset position on the wristband; S8: Rewinding. The processed anti-counterfeiting wristband is wound up by the rewinding roller.

[0012] In step S4, when the image processing system identifies whether the anti-counterfeiting code can be read and compared with the set value in the system, it determines whether they are consistent. If it fails to identify or determines that they are inconsistent, it is determined to be a defective product, and the PLC controller records the position information.

[0013] Compared with existing technologies, the integrated production line of this invention enables continuous production, is easier to operate, improves production efficiency, enhances product quality, monitors coding quality in real time, marks defective products promptly, and improves product accuracy and consistency through a buttoning machine, thus ensuring the stability and reliability of the production line.
