Description
Technical Field
[0001] The present invention relates to the technical field of label card encapsulation, and particularly to an RFID label card encapsulation device. Background Art
[0002] RFID is radio frequency identification technology. An RFID label card is a card that uses radio frequency signals for non-contact data transmission and identifies specific target objects through the transmitted data. It requires no manual intervention and can work in various harsh environments. It can quickly and accurately identify target objects. RFID label cards are often used in identity recognition systems such as access control cards. The shape of such RFID label cards is generally an elliptical cylinder structure. When in use, an RFID label card is generally encapsulated with a plastic film on its outer surface to isolate air and improve the service life of the internal chip.
[0003] When the existing device encapsulates a plastic film on an RFID label card, the encapsulation film is generally two elliptical plastic films. During encapsulation, the two films are respectively placed at both ends of the RFID label card, and then the edges of the two films are squeezed by a heat sealer. Since the side surface of the elliptical label card is a vertical surface, there will be a cavity between the edge of the film encapsulated in this way and the side surface of the label card. After long-term use, the label card and the film will move relative to each other, easily causing the outer film to be damaged under the extrusion of the label card, and the sealing performance is poor. The existing device cannot automatically encapsulate the elliptical label, and the efficiency of manual encapsulation is very low. Summary of the Invention

Then, while the fixing ring drives the hot melt rod to rotate, the two second motors drive the hot melt rods to rotate respectively, and the two hot melt rods start to heat, so that the two hot melt rods can shape the side face of the plastic film into a vertical structure that completely fits the side face of the label card. Then, the first electric telescopic rod drives the fourth electric telescopic rod to rise to a position half the height of the side face of the label card. Then, while the first electric telescopic rod and the fourth electric telescopic rod expand and contract, the third motor rotates, so that the end of the hot melt rod rotates to the horizontal position on the premise that the position remains unchanged, shaping a circular connecting film on the side face of the plastic film. Then, the two shaped sealing films are respectively clamped on the upper and lower end faces of the label card, and the two hot melt rods heat-seal and fix the connecting film on the outermost side of the plastic film, so that the plastic film can be completely tightly attached to the surface of the label card, preventing relative movement between the label card and the plastic film when the sealed label card moves, preventing the plastic film from being damaged due to collision, and improving the service life of the sealed label card.

[0034] Specifically, the first electric telescopic rod 28 and the fourth electric telescopic rod 217 extend. At the same time, the third motor 216 drives the second fixing body 211 to rotate 90°, ensuring that the end of the rotated hot melt rod 214 remains stationary. Then, while the fixed ring 26 drives the hot melt rod 214 to rotate, the two second motors 213 respectively drive the hot melt rods 214 to rotate, and the two hot melt rods 214 start to heat, so that the two hot melt rods 214 can shape the side surface of the plastic-sealing film into a vertical structure that completely fits the side surface of the label card.
[0035] A polishing mechanism 3 for polishing the surface of the elliptical label card is provided at the upper end of the main body plate 1.
[0036] The grinding mechanism 3 includes a first limiting groove 31 opened at the upper end of the main body plate 1. A first limiting body 34 is slidably fitted in the first limiting groove 31. A third electric telescopic rod 36 is fixedly connected to the upper end of the first limiting body 34.

The side of the first threaded rod 32 is arranged in cooperation with the threaded hole 35.
[0039] Specifically, the first threaded rod 32 cooperates to drive the first limiting body 34 to reciprocate along the first limiting groove 31. While moving, the third electric telescopic rod 36 extends. The seventh motor 313 drives the grinding rod 311 to rotate to a horizontal position. The third electric telescopic rod 36 drives the side of the grinding rod 311 to contact the upper end surface of the label card. Then the fifth motor 310 is started, and the fifth motor 310 drives the grinding rod 311 to grind the upper end surface of the label card.
[0040] A fixing mechanism 4 for limiting the film and the label card is arranged at the upper end of the main body plate 1.
[0041] The fixing mechanism 4 includes a third placement groove 41 opened at the upper end of the main body plate 1. A sixth motor 42 is fixedly connected to the main body plate 1 in the third placement groove 41. The transmission shaft end of the sixth motor 42 is fixedly connected to a fourth fixing body 43. A fourth empty groove 48 is opened at the upper end of the fourth fixing body 43. A plurality of through holes 45 are opened at the lower end of the fourth fixing body 43. A partition plate 46 is fixedly connected to the inner side surface of the fourth fixing body 43. An air pump 47 is arranged at the end of the partition plate 46.
[0042] A porous plate 44 is fixedly connected to the fourth fixing body 43 in the fourth empty groove 48. The upper end of the porous plate 44 is of a flexible structure. The upper end of the porous plate 44 is higher than the upper end of the fourth fixing body 43.
[0043] Specifically, place the label card with an ellipsoidal structure on the upper end face of the porous plate 44, and then start the air pump 47. The air pump 47 drives the air pressure above the partition plate 46 to decrease, thereby fixing the label card above the porous plate 44.
[0044] During use, place the main body plate 1 on a horizontal plane. First, place the label card with an ellipsoidal structure on the upper end face of the porous plate 44, and then start the air pump 47. The air pump 47 drives the air pressure above the partition plate 46 to decrease, thereby fixing the label card above the porous plate 44. At the same time, start the fourth motor 33. The fourth motor 33 drives the first threaded rod 32 to rotate. The first threaded rod 32 cooperates to drive the first limiting body 34 to reciprocate along the first limiting groove 31. While moving, the third electric telescopic rod 36 extends. The seventh motor 313 drives the grinding rod 311 to rotate to a horizontal position. The third electric telescopic rod 36 drives the side surface of the grinding rod 311 to contact the upper end face of the label card. Then, the fifth motor 310 is started. The fifth motor 310 drives the grinding rod 311 to grind the upper end face of the label card. Then, the fourth motor 33 drives the first limiting body 34 to move outwards, so that the end of the grinding rod 311 grinds the side surface of the label card. At the same time, the sixth motor 42 is started. The sixth motor 42 drives the fourth fixing body 43 to rotate, thereby driving the label card to rotate. The surface of the label card can be completely ground, so that the upper and lower end faces of the ground label card are flat ellipsoidal structures, and the side surface is a vertical structure, which is convenient for the subsequent plastic film to be closely fixed on the surface of the label card.
[0045] After the polishing is completed, the pressure sensor on the side of the polishing rod 311 is connected to the controller, and the surface shape of the label card after polishing can be drawn. Then, the label card is removed, and the oval plastic film is placed on the upper end surface of the porous plate 44. At this time, the air pump 47 continues to limit the position of the plastic film, and the area of the plastic film is slightly larger than that of the porous plate 44. The first motor 25 is started, and the first motor 25 drives the gear 22 to rotate. The gear 22 cooperates to drive the toothed ring 27 to rotate, and the toothed ring 27 drives the fixed ring 26 to rotate at a constant speed. At this time, the first electric telescopic rod 28 extends, driving the first electric telescopic rod 28 to move to a position corresponding to the upper end surface of the porous plate 44. Then, the fourth electric telescopic rod 217 extends, driving the hot melt rod 214 to move to the side of the plastic sealing mold. According to the surface drawing of the label card, the length from the end of the hot melt rod 214 to the center of the plastic film is made the same as the length from the side of the label card at the same position to the center. Then, the first electric telescopic rod 28 and the fourth electric telescopic rod 217 extend, and at the same time, the third motor 216 drives the second fixing body 211 to rotate 90°, ensuring that the end of the hot melt rod 214 after rotation remains stationary. Then, while the fixed ring 26 drives the hot melt rod 214 to rotate, the two second motors 213 drive the hot melt rod 214 to rotate respectively, and the two hot melt rods 214 start to heat, so that the two hot melt rods 214 can shape the side of the plastic film into a vertical structure that completely fits the side of the label card. Then, the first electric telescopic rod 28 drives the fourth electric telescopic rod 217 to rise to a position half the height of the side of the label card. Then, while the first electric telescopic rod 28 and the fourth electric telescopic rod 217 extend and retract, the third motor 216 rotates, so that the hot melt rod 214 rotates to a horizontal position on the premise that the end position of the hot melt rod 214 remains unchanged, shaping a circular connecting film on the side of the plastic film. Then, the two shaped plastic films are respectively clamped on the upper and lower end faces of the label card, and the two hot melt rods 214 perform hot melting fixation on the outermost connecting film of the plastic film, so that the plastic film can completely adhere to the surface of the label card, preventing relative movement between the label card and the plastic film when the sealed label card moves, preventing damage to the plastic film due to collision, and improving the service life of the sealed label card.
