Description

Technical Field

[0001] The present invention belongs to the technical field of RFID tag production, and particularly relates to a slitting device for RFID tag production. Background Art

[0002] In the context of the booming development of modern Internet of Things technology, RFID (Radio Frequency Identification) technology, as a key means of information collection and identification, has been widely used. As an indispensable part of the RFID system, the production quality and efficiency of RFID tags directly affect the performance and application effect of the entire RFID system.

[0003] In the production process of RFID tags, slitting is a crucial process. Many problems have emerged in the actual application of traditional RFID tag slitting devices.

[0004] 1. If the adhesion between the face material and the bottom material of the tag is not well controlled, adhesion may occur during slitting, resulting in incomplete slitting, making it difficult to separate the slitted tags, and affecting production efficiency and product quality; 2. During the slitting process, friction between the material, the cutting tool, and the equipment easily generates static electricity. Static electricity will adsorb dust and other impurities, making the tag surface unclean, affecting subsequent processes such as printing and encapsulation; in severe cases, it may also cause damage to electronic components, affecting the performance of RFID tags, and even causing sparks, posing a safety hazard.

[0005] In summary, it is of great practical significance and market value to develop a slitting device for RFID tag production that can improve slitting accuracy, enhance production efficiency, and reduce the impact of static electricity. Summary of the Invention

[0006] The purpose of the present invention is to provide a slitting device for RFID tag production to address the problems of incomplete slitting and easy adhesion of existing RFID tags.

[0007] The present invention is achieved through the following technical solutions: A slitting device for RFID tag production, including a frame. A workbench is provided at the upper end of the frame. A support frame is provided at the upper end of the workbench. Two unwinding reels are provided at the upper left end of the support frame, and two winding reels are provided at the lower end. At the upper right part of the support frame, there is a slitting top plate. A slitting mechanism is provided below the slitting top plate for automatically cutting the RFID tags on the RFID tag coil material. An unloading mechanism is provided below the support frame where the slitting mechanism is located for conveying the cut RFID tags out. A plurality of guide rollers are provided on the support frame. After the RFID tag coil material is unwound from the unwinding reel, it passes through the plurality of guide rollers in sequence and is wound on the winding reel, and the RFID tag coil material passes between the slitting top plate and the slitting mechanism. A winding motor is provided outside the winding reel on the support frame, and the winding reel is driven to rotate by the winding motor to realize the unwinding and winding actions.

[0008] Preferably, the slitting mechanism includes fixed brackets symmetrically arranged on both sides of the support frame. A slide bar and a bidirectional threaded rod are respectively provided between the two fixed brackets. The two ends of the slide bar are respectively fixedly connected to the two fixed brackets, and the two ends of the bidirectional threaded rod are respectively rotatably connected to the two fixed brackets. Moving seats are symmetrically sleeved on the slide bar and the bidirectional threaded rod. The moving seat is slidably arranged with the slide bar and is threadedly connected with the bidirectional threaded rod. One end of the bidirectional threaded rod passes through the fixed bracket and is connected with a driving wheel disc. A telescopic cylinder is installed on each moving seat, and a cutter head assembly is provided at the movable end of the telescopic cylinder. The cutter head assembly is provided with two cutter heads.

[0009] During use, by rotating the driving wheel disc, the bidirectional threaded rod can be driven to rotate, thereby adjusting the positions of the moving seat and the cutter head assembly. The cutter head assembly moves up and down by the telescopic cylinder to slit the RFID tags on the RFID tag coil material.

[0010] Preferably, the cutter head assembly includes an outer cutter head and an inner cutter head. The inner cutter head is movably arranged in the inner cavity of the outer cutter head, and the cutting edge of the inner cutter head is lower than that of the outer cutter head. In the middle of the lower end of the outer cutter head, there is an outer sleeve tube. In the middle of the lower end of the inner cutter head, there is an inner rod. The inner rod passes through the outer sleeve tube and extends downward, and is connected to the movable end of the telescopic cylinder. A limiting plate is provided on the outer wall of the lower part of the inner rod. A first spring is sleeved outside the outer sleeve tube. The lower end of the first spring abuts against the limiting plate, and the upper end abuts against the lower end face of the outer cutter head, and the first spring is in a compressed state. A material ejecting plate is provided in the inner cavity of the inner cutter head. The material ejecting plate is inclined, and the lower end of the material ejecting plate is connected to the bottom of the inner cavity of the inner cutter head through a spring matrix composed of a plurality of second springs. The lengths of the springs on one side of the spring matrix are greater than those on the other side, so as to ensure that the material ejecting plate is in an inclined state. During use, the telescopic cylinder drives the inner rod, inner cutter head, and outer cutter head to rise synchronously. Since the cutting edge position of the outer cutter head is higher, it first contacts the RFID label web and directionally cuts the RFID label web on the top plate, thereby cutting the RFID labels on the RFID label web. The telescopic cylinder continues to rise, compressing the first spring. The inner rod drives the inner cutter head to cut the RFID label web upward for a second time, thus fully cutting off the connection between the RFID label and the base material, avoiding incomplete cutting and adhesion phenomena; Meanwhile, during the upward movement of the inner cutter head, the material ejecting plate contacts the RFID label web, compressing the second spring. When the cutting is completed and the cutter head assembly descends, due to the different elastic forces of the second springs on both sides at the lower end of the material ejecting plate, the material ejecting plate is elastically forced by the second springs to eject the cut RFID label to one side, causing it to fall onto the lower discharging mechanism.

[0011] Preferably, a plurality of air outlet holes are provided at the bottom of the inner cutter head, and a rectangular through hole is provided on the higher side of the material ejecting plate.

[0012] When the inner cutter head rises, a cavity is formed between the outer cutter head and the inner cutter head. When the cutter head assembly descends, the outer cutter head moves upward relative to the inner cutter head under the action of the first spring, thereby squeezing the cavity between the outer cutter head and the inner cutter head, causing the internal gas to be instantaneously ejected from the air outlet holes and pass through the edge of the material ejecting plate and the rectangular through hole, blowing the cut RFID label to one side, further enabling the RFID label to smoothly fall onto the lower discharging mechanism.

[0013] Preferably, the discharging mechanism includes a conveyor belt, a conveying motor, and a conveying bracket. Conveying brackets are symmetrically provided on both sides of the fixed bracket. A rotating shaft is rotatably provided at the upper end of the conveying bracket. Both ends of the conveyor belt are rotatably sleeved on the two rotating shafts. The conveying motor is installed outside one of the conveying brackets, and the output end of the conveying motor is connected to the end of the rotating shaft. During use, the conveyor belt is driven to rotate by the rotation of the conveying motor, thereby conveying the RFID labels that fall onto the conveyor belt.

[0014] Preferably, a baffle is provided at the right end of the fixed bracket. The lower end of the baffle is at the same height as the upper end surface of the conveyor belt, and is used to block the RFID labels ejected by the material ejecting plate, enabling them to smoothly fall onto the conveyor belt.

[0015] Preferably, a humidity control mechanism is further provided in the middle of the fixed bracket. The humidity control mechanism includes a humidifier, a connecting pipe, a support plate, a drive box, a spray pipe, and a spray pipe bracket. The humidifier is installed at the lower part of the fixed bracket through a mounting bracket. Both ends of the support plate are connected to both sides of the fixed bracket. Spray pipe brackets are symmetrically arranged on both sides of the upper end of the support plate. Both ends of the spray pipe are rotatably installed on the two spray pipe brackets. The drive box is cylindrical and fixedly installed on the outer wall of one of the spray pipe brackets. An air inlet is provided at the lower end of the drive box, and the air inlet is connected to the air outlet of the humidifier through the connecting pipe. One end of the spray pipe is sealed, and the other end passes through the spray pipe bracket and extends into the drive box, and a gap is reserved between it and the inside of the drive box. A plurality of fan plates are arranged on the outer side of the end of the spray pipe located inside the drive box. A number of spray holes are provided on the outer wall of the spray pipe.

[0016] When the humidified gas enters the drive box from the humidifier, it will drive the fan plates to rotate, thereby driving the spray pipe to rotate. At the same time, the gas entering the drive box will enter the inner cavity from the end opening of the spray pipe and finally flow out from the spray holes of the spray pipe. The moist gas is used to keep the surrounding of the slitting mechanism moist, avoiding static electricity generated by drying and damaging the RFID tag products.

[0017] Preferably, a cover plate is further provided at the upper end of the frame. The lower end of the cover plate is connected to the four corners of the frame through four connecting columns, which plays a role in safety protection and preventing dust from falling on the equipment.

[0018] Preferably, a controller is provided on the front of the frame. The controller is electrically connected to the winding motor, the telescopic cylinder, the conveying motor, and the humidifier respectively, and controls their operations.

[0019] The present invention has the following advantages compared with the prior art: 1. In the present invention, the unwinding roll and the winding roll are integrated on one frame and arranged in a vertically offset manner, thereby reducing the overall occupied space of the slitting equipment. And this slitting equipment can slit two rolls of RFID tag webs at the same time, improving the working efficiency.

[0020] 2. The cutter head assembly in the present invention is composed of an outer cutter head and an inner cutter head, which can perform primary cutting and secondary cutting on the RFID tag web, so as to fully cut off the connection between the RFID tag and the base material, avoiding the phenomenon of incomplete slitting and adhesion.

[0021] 3. In the present invention, by arranging an inclined material ejecting plate in the inner cavity of the inner cutter head, under the action of the second spring, the cut-off RFID tags can be ejected to one side, so that they fall onto the lower discharging mechanism, avoiding affecting the next slitting.

[0022] 4. By providing air vents at the bottom of the inner cutter head and rectangular through-holes on the higher side of the ejector plate, squeezing the cavity between the outer cutter head and the inner cutter head causes the internal gas to instantaneously eject from the air vents, pass through the edge of the ejector plate and the rectangular through-holes, and blow the cut RFID tags to one side, further enabling the RFID tags to smoothly fall onto the lower discharging mechanism.

[0023] 5. By providing a humidity control mechanism to maintain humidity around the cutting mechanism, static electricity generated by dryness is avoided, which could damage the RFID tag products. The flowing gas drives the spray pipe to rotate automatically, enabling the humid gas to be evenly dispersed, thereby enhancing the humidifying effect. BRIEF DESCRIPTION OF THE DRAWINGS

The upper right end of the support frame 11 is provided with a slitting top plate 4. A slitting mechanism 3 is provided below the slitting top plate 4 for automatically cutting the RFID tags on the RFID tag web 12. A discharging mechanism 10 is provided below the support frame 11 and below the slitting mechanism 3 for conveying the cut RFID tags out; A plurality of guide rollers 5 are provided on the support frame 11. After the RFID tag web 12 is unwound from the unwinding reel 6, it passes through the plurality of guide rollers 5 in sequence and is wound on the winding reel 7. The RFID tag web 12 passes between the slitting top plate 4 and the slitting mechanism 3. A winding motor 8 is provided outside the winding reel 7 of the support frame 11. The winding reel 7 is driven to rotate by the winding motor 8 to realize the unwinding and winding actions.

[0028] Among them, please refer toFigure 3 , the slitting mechanism 3 includes fixed brackets 301 symmetrically arranged on both sides of the support frame 11. A slide bar 303 and a bidirectional threaded rod 304 are respectively arranged between the two fixed brackets 301. The two ends of the slide bar 303 are respectively fixedly connected to the two fixed brackets 301, and the two ends of the bidirectional threaded rod 304 are respectively rotatably connected to the two fixed brackets 301; moving seats 302 are symmetrically sleeved on the slide bar 303 and the bidirectional threaded rod 304. The moving seats 302 are slidably arranged with respect to the slide bar 303 and are threadedly connected to the bidirectional threaded rod 304; one end of the bidirectional threaded rod 304 passes through the fixed bracket 301 and is connected to a driving wheel disc 307; a telescopic cylinder 305 is installed on each moving seat 302, and a cutter head assembly 306 is arranged at the movable end of the telescopic cylinder 305. The cutter head assembly 306 is provided with two cutter heads.

[0029] During use, by rotating the driving wheel disc 307, the bidirectional threaded rod 304 can be driven to rotate, thereby adjusting the positions of the moving seats 302 and the cutter head assembly 306. The telescopic cylinder 305 drives the cutter head assembly 306 to move up and down to slit the RFID tags on the RFID tag roll 12.

[0030] Please refer to Figures 6 - 10 , the cutter head assembly 306 includes an outer cutter head 3061 and an inner cutter head 3062. The inner cutter head 3062 is movably arranged in the inner cavity of the outer cutter head 3061, and the cutting edge of the inner cutter head 3062 is lower than that of the outer cutter head 3061; a jacket tube 3065 is connected to the middle of the lower end of the outer cutter head 3061, and an inner rod 3066 is connected to the middle of the lower end of the inner cutter head 3062. The inner rod 3066 passes through the jacket tube 3065 and extends downward, and is connected to the movable end of the telescopic cylinder 305; a limiting plate is arranged on the outer wall of the lower part of the inner rod 3066, and a first spring 3064 is sleeved outside the jacket tube 3065. The lower end of the first spring 3064 abuts against the limiting plate, and the upper end abuts against the lower end face of the outer cutter head 3061, and the first spring 3064 is in a compressed state; A material ejecting plate 3063 is arranged in the inner cavity of the inner cutter head 3062. The material ejecting plate 3063 is inclined, and the lower end of the material ejecting plate 3063 is connected to the bottom of the inner cavity of the inner cutter head 3062 through a spring matrix composed of a plurality of second springs 3067; the lengths of the springs on one side of the spring matrix are greater than those on the other side, so as to ensure that the material ejecting plate 3063 is in an inclined state; During use, the telescopic cylinder 305 drives the inner rod 3066, the inner cutter head 3062, and the outer cutter head 3061 to rise synchronously. Since the cutting edge position of the outer cutter head 3061 is high, it first contacts the RFID label web 12 and directionally cuts the RFID label web 12 into the top plate 4, thereby cutting the RFID labels on the RFID label web 12. The telescopic cylinder 305 continues to rise, the first spring 3064 is compressed, and the inner rod 3066 drives the inner cutter head 3062 to perform secondary cutting on the RFID label web 12 upward, so as to fully cut off the connection between the RFID label and the base material, avoiding incomplete cutting and adhesion phenomena. Meanwhile, during the rising process of the inner cutter head 3062, the material ejecting plate 3063 contacts the RFID label web 12, and the second spring 3067 is compressed. When the cutting is completed and the cutter head assembly 306 descends, due to the different elastic forces of the second springs 3067 on both sides of the lower end of the material ejecting plate 3063, the material ejecting plate 3063 is elastically pushed to one side by the elastic force of the second spring 3067, so that the cut RFID label is bounced to one side and falls onto the lower discharging mechanism 10.

[0031] A plurality of air outlet holes 3069 are provided at the bottom of the inner cutter head 3062, and a rectangular through hole is provided on the higher side of the material ejecting plate 3063.

[0032] Since a cavity is formed between the outer cutter head 3061 and the inner cutter head 3062 when the inner cutter head 3062 rises, when the cutter head assembly 306 descends, the outer cutter head 3061 moves upward relative to the inner cutter head 3062 under the action of the first spring 3064, thereby squeezing the cavity between the outer cutter head 3061 and the inner cutter head 3062, so that the internal gas is instantaneously ejected from the air outlet holes 3069 and passes through the edge of the material ejecting plate 3063 and the rectangular through hole, blowing the cut RFID label to one side, and further enabling the RFID label to smoothly fall onto the lower discharging mechanism 10.

[0033] Please refer to Figure 4 , the discharging mechanism 10 includes a conveyor belt 1001, a conveyor motor 1002, and a conveyor support 1003. Conveyor supports 1003 are symmetrically provided on both sides of the fixed support 301. A rotating shaft is rotatably provided at the upper end of the conveyor support 1003. Both ends of the conveyor belt 1001 are rotatably sleeved on the two rotating shafts. The conveyor motor 1002 is installed on the outside of one of the conveyor supports 1003, and the output end of the conveyor motor 1002 is connected to the end of the rotating shaft. During use, the conveyor motor 1002 rotates to drive the conveyor belt 1001 to rotate, thereby conveying the RFID labels falling onto the conveyor belt 1001.

[0034] The right end of the fixed bracket 301 is provided with a baffle 13. The lower end of the baffle 13 is at the same height as the upper end surface of the conveyor belt 1001, and is used to block the RFID tags ejected by the material ejecting plate 3063 so that they can smoothly fall onto the conveyor belt 1001.

[0035] Embodiment Two In order to reduce the static electricity generated during slitting of the slitting equipment from damaging the RFID tags, on the basis of Embodiment One, the following scheme is added in this embodiment: Please refer to Figure 11 and Figure 12 , a humidity control mechanism 9 is further provided in the middle of the fixed bracket 301. The humidity control mechanism 9 includes a humidifier 901, a connecting pipe 902, a support plate 903, a driving box 904, a spraying pipe 905, and a spraying pipe bracket 906. The humidifier 901 is installed at the lower part of the fixed bracket 301 through a mounting frame. The two ends of the support plate 903 are connected to both sides of the fixed bracket 301. Symmetrically arranged spraying pipe brackets 906 are provided on both sides of the upper end of the support plate 903. Both ends of the spraying pipe 905 are rotatably installed on the two spraying pipe brackets 906. The driving box 904 is cylindrical and is fixedly installed on the outer wall of one of the spraying pipe brackets 906. An air inlet is provided at the lower end of the driving box 904, and the air inlet is connected to the air outlet of the humidifier 901 through the connecting pipe 902; One end of the spraying pipe 905 is sealed, and the other end passes through the spraying pipe bracket 906 and extends into the driving box 904, and there is a gap between it and the inside of the driving box 904. A plurality of fan plates 907 are provided on the outer side of the end of the spraying pipe 905 located inside the driving box 904. A number of spray holes 908 are provided on the outer wall of the spraying pipe 905.

[0036] When the humidifying gas enters the driving box 904 from the humidifier 901, it will drive the fan plates 907 to rotate, thereby driving the spraying pipe 905 to rotate. At the same time, the gas entering the driving box 904 will enter the inner cavity from the end opening of the water spraying pipe, and finally flow out from the spray holes 908 of the spraying pipe 905, using the moist gas to keep the surrounding of the slitting mechanism 3 moist and avoid static electricity generated by drying from damaging the RFID tag products.

[0037] A cover plate 102 is further provided at the upper end of the frame 1. The lower end of the cover plate 102 is connected to the four corners of the frame 1 through four connecting columns, which plays a role in safety protection and preventing dust from falling onto the equipment. A controller 101 is provided on the front of the frame 1. The controller 101 is electrically connected to the winding motor 8, the telescopic cylinder 305, the conveying motor 1002, and the humidifier 901 respectively, and controls their operations.

[0038] The working principle of the present invention: During use, the RFID tag roll 12 is installed on the unwinding reel 6, and the end of the RFID tag roll 12 is sequentially passed through five guide rollers 5 (such as Figure 3is wound around the take-up reel 7. The take-up motor 8 is started, and the take-up motor 8 drives the take-up reel 7 to wind up, while the unwind reel 6 unwinds at the same time; the controller 101 controls the telescopic cylinder 305 to extend, driving the inner rod 3066, the inner cutter head 3062, and the outer cutter head 3061 to rise synchronously. Since the cutting edge position of the outer cutter head 3061 is high, it first contacts the RFID tag web 12 and directs the cutting of the RFID tag web 12 to the top plate 4, thereby cutting the RFID tags on the RFID tag web 12. The telescopic cylinder 305 continues to rise, the first spring 3064 is compressed, and the inner rod 3066 drives the inner cutter head 3062 to perform a secondary cut on the RFID tag web 12, thus fully cutting off the connection between the RFID tag and the base material, avoiding incomplete cutting and adhesion; at the same time, during the rising process of the inner cutter head 3062, the elastic plate 3063 contacts the RFID tag web 12, and the second spring 3067 is compressed. When the cutting is completed and the cutter head assembly 306 descends, due to the different elastic forces of the second springs 3067 on both sides of the lower end of the elastic plate 3063, the elastic plate 3063 is under the elastic force of the second spring 3067, and the cut-off RFID tags are bounced to one side, causing them to fall into the lower discharging mechanism 10; then the conveyor motor 1002 rotates to drive the conveyor belt 1001 to rotate, thereby conveying the RFID tags that have fallen onto the conveyor belt 1001 out. At the same time, the humidifier 901 operates. After the humidified gas enters the drive box 904 from the humidifier 901, it will drive the fan plate 907 to rotate, thereby driving the spray pipe 905 to rotate. At the same time, the gas entering the drive box 904 will enter the inner cavity from the end opening of the water spray pipe and finally flow out from the spray holes 908 of the spray pipe 905. The humidified gas is used to keep the surroundings of the cutting mechanism 3 moist, avoiding static electricity generated by drying and damaging the RFID tag products; and the flowing gas drives the spray pipe 905 to rotate automatically, enabling the humidified gas to be evenly dispersed, thereby enhancing the humidifying effect.
