Description

Technical Field

[0001] This utility model relates to the field of label folding technology, specifically a folding device for producing RFID smart tags with dynamic correction function. Background Technology

[0002] RFID tags are the "digital ID cards" for asset digitization in the Internet of Things era. Their diverse technical characteristics and scenario adaptability make them a core tool in fields such as smart manufacturing and smart healthcare. In the future, with the integration of technologies and the increasing demand for environmental protection, RFID tags will evolve towards a smarter and greener direction, promoting the further implementation of the Internet of Everything. In the production process of RFID smart tags, the substrate (such as antenna, face material, backing paper, etc.) often needs to be precisely folded to meet the requirements of packaging or lamination processes.

[0003] Traditional folding equipment often uses a fixed pressing and folding mechanism, which is difficult to adapt to label substrates of different thicknesses or materials, easily leading to uneven creases or material damage. It also lacks dynamic correction function, and the folding position is prone to deviation, affecting the alignment accuracy between the label antenna and the chip. To address this, we propose a folding equipment for the production of RFID smart tags with dynamic correction function. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a folding device for the production of RFID smart tags with dynamic correction function. The device uses an elastic pressure roller mechanism to adaptively adjust the pressure to avoid material damage; it combines a correction sensor and an infrared detector to achieve dynamic correction and online quality monitoring to ensure folding accuracy; and it uses a bidirectional screw and an adjustable mold to quickly adapt to different specifications of substrates, thereby improving production efficiency and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding device for producing RFID smart tags with dynamic correction function, comprising a box and a folding unit;

[0006] Box body: A fixing frame is provided on the left side of the top surface, and a material guiding unit is provided on the top surface of the box body;

[0007] The pressing and folding unit includes a roller frame, a pressure roller, a spring, a spring seat, a conveyor roller, a limiting rod, and a limiting groove. The fixing frame is fixed to the left side of the top surface of the housing. Conveyor rollers are rotatably installed on both sides inside the fixing frame. There are two spring seats, which are fixed to the right side of the fixing frame in a front-to-back manner. A spring is fixedly installed inside the spring seat. The top of the spring is connected to one side of the bottom surface of the roller frame. The pressure roller is rotatably installed inside the roller frame. There are two limiting rods, which are fixed to the bottom surface of the roller frame in a front-to-back manner. There are two limiting grooves, which are opened on the right side of the top surface of the fixing frame in a front-to-back manner.

[0008] It also includes a controller, which is installed on the front side of the top surface of the enclosure, and the input terminal of the controller is electrically connected to the output terminal of an external power supply.

[0009] The spring can dynamically adjust the height of the pressure roller. Together with the conveyor roller, it can be used for folding during the production of RFID smart tags to adapt to substrates of different thicknesses, avoiding damage from excessive pressure or insufficient folding. The limiting rod slides inside the limiting groove to increase the stability of the roller frame lifting.

[0010] Furthermore, the pressing and folding unit also includes a bracket, electric push rods, sponge pressure strips, a linear motor, a limiting frame, a frame, and guide rollers. The bracket is fixed to the left side of the top surface of the fixed frame. Electric push rods are provided on both sides of the top surface of the bracket. The bottom end of the electric push rod is connected to one side of the top surface of the sponge pressure strip. The linear motor has two stators, one of which is connected to the front and rear sides of the fixed frame. A limiting frame is installed on the top surface of the linear motor's moving part. The frame is fixed to the right side of the top surface of the housing. Guide rollers are rotatably installed on both sides inside the frame. The input ends of the electric push rods and the linear motor are electrically connected to the output end of the controller. Activating the electric push rods drives the sponge pressure strips to press down to flexibly fix the RFID smart tags, avoiding deformation of the tags caused by hard friction. The linear motor can adjust the position of the limiting frame to prevent deviation during the transport of the RFID smart tags.

[0011] Furthermore, the pressing and folding unit also includes a rotating wheel, rubber rollers, a bidirectional screw, and a limiting plate. The rotating wheel is fixed to the top surface of the frame, and the bottom end of the rotating wheel is connected to the top end of the bidirectional screw. The threads at both ends of the bidirectional screw are opposite. There are four rubber rollers, which are installed in pairs inside the through grooves on both sides of the frame. There are two limiting plates, and the screw holes on their surfaces are respectively connected to the outer threads of the bidirectional screw. The through holes on the surface of the limiting plate are slidably connected to the guide roller. Rotating the rotating wheel drives the bidirectional screw to rotate to adjust the position of the limiting plate to adapt to different width substrates and prevent substrate misalignment.

[0012] Furthermore, the material guiding unit includes a concave mold, a convex mold, a support rod, an adjusting frame, an adjusting groove, and a screw. There are two adjusting grooves, which are respectively opened on the front and rear sides of the top surface of the box. A screw is rotatably installed inside the adjusting groove. The screw is threadedly connected to the screw hole on the surface of the adjusting frame. The adjusting frame slides inside the adjusting groove. The top surface of the adjusting frame is connected to the bottom end of the support rod. The top ends of the two support rods are respectively connected to the middle of the outer side of the concave mold and the convex mold. The inner side surfaces of the concave mold and the convex mold are correspondingly engaged. Rotating the screw drives the adjusting frame to slide inside the adjusting groove to adjust the distance between the concave mold and the convex mold to meet different crease depth requirements.

[0013] Furthermore, it also includes a correction sensor, a frame, and an infrared detector. The frame is mounted on the top surface of the support, and the correction sensor is placed inside the frame. The infrared detector is fixed on the bottom surface inside the support frame. The output of the correction sensor is electrically connected to the input of the controller, and the input of the infrared detector is electrically connected to the output of the controller. The correction sensor and the infrared detector are configured to monitor the substrate position offset in real time, thereby achieving dynamic correction.

[0014] Furthermore, it also includes a connecting frame and a limiting roller. The connecting frame is installed on the right side of the fixed frame, and the limiting roller is rotatably installed inside the connecting frame. The limiting roller can guide the substrate to pre-align before entering the pressing and folding area, reducing the subsequent correction load.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This folding device for producing RFID smart tags with dynamic correction function has the following advantages:

[0016] 1. The height of the pressure roller can be dynamically adjusted by the spring.

The input of the controller 10 is electrically connected to the output of an external power supply. The spring 23 can dynamically adjust the height of the pressure roller 22.

[0029] The working principle of the folding device for producing RFID smart tags with dynamic correction function provided by this utility model is as follows: First, the substrate for making RFID smart tags enters the frame 213 through the rubber roller 216. The rotating wheel 215 drives the bidirectional screw 217 to rotate to adjust the position of the limiting plate 218 to adapt to substrates of different widths and prevent substrate misalignment. Then, the rotating screw 36 drives the adjusting frame 34 to slide inside the adjusting groove 35 to adjust the distance between the concave mold 31 and the convex mold 32 to meet different crease depth requirements. The limiting roller 9 can guide the substrate to pre-align before entering the folding area. The substrate then enters the top surface of the conveyor roller 25. The spring 23 can dynamically adjust the height of the pressure roller 22. In conjunction with the conveyor roller 25, the RFID smart tag can be folded during the production process to accommodate substrates of different thicknesses and avoid damage from excessive pressure or insufficient folding. The electric push rod 29 is activated to drive the sponge pressure strip 210 to press down and flexibly fix the RFID smart tag, avoiding deformation of the tag caused by hard friction. The set correction sensor 5 and infrared detector 7 monitor the position deviation of the substrate in real time. The linear motor 211 can be activated to adjust the position of the limit frame 212 to prevent deviation during the conveying of the RFID smart tag.
