As a data carrier, it automatically identifies a target object through a radio frequency signal and obtains relevant data, playing roles such as identification, item tracking, and information collection, and has been applied in many fields such as industrial and commercial automation. The production and processing of electronic tags is to clamp and laminate a chip between two layers of backing paper tapes, and then cut the laminated tape into RFID sheet products to achieve the chip production of electronic tags.

[0054] As Figures 1 - 18 shown, an automatic electronic tag production system includes a material feeding mechanism 2, a compounding mechanism 3, a slitting mechanism 4, and a waste treatment mechanism 5 arranged on a frame 1;

[0055] The material feeding mechanism 2 includes a film covering unwinding assembly 21, a chip carrier film unwinding assembly 22, a resilient strip unwinding assembly 23 arranged on the frame 1, and an indentation assembly 24 arranged on the frame 1 and used for pre-pressing strip grooves on the surface of the film covering to accommodate the resilient strips;

[0056] The waste treatment mechanism 5 includes a rejection assembly 51 arranged on the frame 1 and used for separating the resilient strip waste and the film covering waste, and a winding assembly 52 arranged on the frame 1 and used for evenly winding up the film covering waste;

[0057] The film covering unwinding assembly 21 releases a double-layer film covering 6, and the double-layer film covering 6 is then separated into a first-layer film covering 61 and a second-layer film covering 62. The chip carrier film unwinding assembly 22 releases a chip carrier film 7. The resilient strip unwinding assembly 23 releases two groups of resilient strips 8, and adjusts the distance between the two groups of resilient strips. Synchronously, the indentation assembly 24 adjusts the distance between the pre-pressed strip grooves on the surface of the first-layer film covering. The indentation assembly 24 pre-presses strip grooves corresponding to the positions of the distances between the two groups of resilient strips on the surface of the first-layer film covering. The compounding mechanism 3 first bonds and composites the chip carrier film and the two groups of resilient strips on the surface of the first-layer film covering, and then bonds and composites the second-layer film covering on the surface of the first-layer film covering. The slitting mechanism 4 roll-cuts out electronic tags of the same specification. The rejection assembly 51 separates the resilient strip waste 91 from the film covering waste 92, and the winding assembly 52 collects the film covering waste.

[0058] It should be noted that the film covering is a backing tape, made of waterproof paper, and the resilient strip is made of a plastic strip with toughness.

[0059] In this embodiment, through the cooperation of the arranged material feeding mechanism 2 and compounding mechanism 3, on the one hand, during the process of compounding the electronic tag, a resilient strip can be embedded in the electronic tag, increasing the toughness of the electronic tag, preventing the electronic tag from curling, and improving the service life of the electronic tag; on the other hand, the distance between the two resilient strips can be adjusted to adapt to chips of different specifications, producing electronic tags of different specifications. The degree of automation is relatively high, the structural linkage is good, and the electronic tags can be mass-produced automatically, increasing the economic benefits of the enterprise.

[0060] Specifically, first, the first unwind unit 211 unwinds the double-layered film, the material separation unit 212 separates the double-layered film into the first-layer film and the second-layer film, the chip carrier film unwind assembly 22 unwinds the chip carrier film, the second unwind unit 231 unwinds two sets of resilient strips, and the material separation unit 212 adjusts the spacing between the two sets of resilient strips and synchronously adjusts the spacing of the pre-pressed strip grooves on the surface of the first-layer film by the indentation assembly 24; then, the upper pressing unit 241 presses up the middle part of the first-layer film to form a ridge, the groove pressing unit 242 pre-presses strip grooves on the surface of the first-layer film for accommodating the resilient strips, and the shaping unit 243 maintains the shape of the pressed grooves during the conveyance of the first-layer film; then, the first bonding assembly 31 sprays adhesive onto the surface of the first-layer film after groove pressing and bonds and composites the chip carrier film and the two sets of resilient strips onto the surface of the first-layer film, and the second bonding assembly 32 sprays adhesive onto the surface of the second-layer film and bonds and composites the second-layer film onto the surface of the first-layer film; then, the slitting mechanism 4 cuts out electronic tags of the same specification, collects the electronic tag products, and outputs waste materials; then, the rejection assembly 51 separates the resilient strip waste materials from the film waste materials and collects them, the folding unit 522 intermittently folds the longitudinal part of the film waste materials, and the winding roller 521 uniformly collects the film waste materials.

[0061] Furthermore, as Figures 4 - 10 shown, the film unwind assembly 21 includes a first unwind unit 211 disposed on the frame 1 and wound with the double-layered film, and a material separation unit 212 disposed on the frame 1 and used for separating the double-layered film;

[0062] The material separation unit 212 includes two sets of material separation rollers 2121 rotatably disposed on the frame 1 and a material separation plate 2122 disposed between the two material separation rollers 2121;

[0063] It should be noted that the first unwind unit 211 includes a first unwind reel, which is driven by an existing stepping motor and is equipped with an existing speed regulating device to convey the double-layered film and adjust the conveying speed of the double-layered film;

[0064] The resilient strip unwind assembly 23 includes a second unwind unit 231 disposed on the frame 1 and wound with two sets of resilient strips, and an adjustment unit 232 disposed on the frame 1 and used for adjusting the conveying spacing between the two sets of resilient strips;

[0065] The adjusting unit 232 includes a first cross bar 2321 arranged on the frame 1, two groups of first sliding columns 2322 symmetrically and slidably arranged on the first cross bar 2321, a first guide wheel 2323 rotatably arranged on the first sliding column 2322 and used for conveying the ductile strip, a first bidirectional threaded rod 2324 rotatably arranged on the frame 1, two groups of first threaded blocks 2325 threadedly arranged on the first bidirectional threaded rod 2324, a first connecting rod 2326 arranged between the first threaded block 2325 and the first sliding column 2322, and a driving member arranged on the frame 1 and used for driving the first bidirectional threaded rod 2324. The driving member is an existing stepper motor;

[0066] It should be noted that the second unwinding unit 231 includes a second unwinding cylinder, which is driven by an existing stepper motor and is equipped with an existing speed regulating device to convey the ductile strip and adjust the conveying speed of the ductile strip;

[0067] It should also be noted that the chip carrier film unwinding assembly 22 includes a third unwinding cylinder 221, which is driven by an existing stepper motor and is equipped with an existing speed regulating device to convey the chip carrier film and adjust the conveying speed of the chip carrier film.

[0068] In this embodiment, by providing the feeding mechanism 2, on the one hand, the double-layer coating film, the chip carrier film, and the two groups of ductile strips can be released synchronously, and the conveying speeds of each can be adjusted, which is convenient for synchronously laminating the three; on the other hand, the conveying distance between the two groups of ductile strips can be automatically adjusted to adapt to different specifications of electronic tags.

[0069] Specifically, the first unwinding unit 211 releases the double-layer coating film. The double-layer coating film is divided into the first-layer coating film and the second-layer coating film by the material dividing plate 2122 and the material dividing roller 2121 and continues to be conveyed forward. The second unwinding unit 231 synchronously releases two groups of ductile strips. The driving member drives the two first threaded blocks 2325 to move through the first bidirectional threaded rod 2324, so that the first threaded blocks 2325 drive the first sliding columns 2322 to approach or move away from each other on the first cross bar 2321 through the first connecting rod 2326, that is, the distance between the two first guide wheels 2323 is adjusted. The two first guide wheels 2323 respectively convey the two groups of ductile strips, that is, the conveying distance between the two groups of ductile strips is adjusted.

[0070] Further, as Figures 4 - 8 shown, the indentation assembly 24 includes an upper lifting unit 241 arranged on the frame 1 and used for lifting the middle part of the first-layer coating film, a grooving unit 242 arranged above the upper lifting unit 241 and synchronously linked with the adjusting unit 232, and a shaping unit 243 arranged on the frame 1 and used for maintaining the groove shape during the conveying of the first-layer coating film;

[0071] The upper pressing unit 241 includes a flat plate 2411 disposed on the frame 1, a sunken opening formed in the middle of the flat plate 2411, two groups of sunken plates 2412 symmetrically disposed at the bottom of the sunken opening, a plurality of groups of first sliding holes formed in the sunken plates 2412, first sliders 2413 slidably disposed on the first sliding holes, a reset elastic member disposed between the lower end of the first sliding hole and the first slider 2413, and a top wheel 2414 rotatably disposed between two opposite first sliders 2413;

[0072] The groove pressing unit 242 includes two groups of groove pressing tracks 2421 slidably disposed on the flat plate 2411 and respectively located directly below the first guide wheels 2323, a second connecting rod 2422 disposed between the groove pressing track 2421 and the first threaded block 2325, a first hydraulic member 2423 disposed on the second connecting rod 2422 through an ear plate, a wheel frame disposed on the output shaft of the first hydraulic member 2423, a pressing wheel 2424 disposed on the wheel frame and matching with the groove pressing track 2421, and a pressing rod 2425 disposed on the wheel frame through an L-shaped hanging rod and matching with the groove pressing track 2421;

[0073] It is worth mentioning that the cross section of the groove pressing track 2421 is a semi-circular groove, which matches the toughness strip.

[0074] In this embodiment, through the cooperation of the upper pressing unit 241 and the groove pressing unit 242, on the one hand, it is possible to pre-press a groove for accommodating the toughness strip on the surface of the first layer of film, so that the surface of the first layer of film can more tightly wrap the toughness strip, increasing the contact area between the toughness strip and the surface of the first layer of film and improving the firmness of the bonding and compounding of the toughness strip and the surface of the first layer of film; on the other hand, during the groove pressing operation, the middle part of the first layer of film can be pushed upward to form a ridge, so that the two sides of the first layer of film converge towards the middle by a specified distance, leaving space for pressing two grooves and avoiding lateral tearing of the first layer of film during the pressing of the two grooves, ensuring the integrity of the first layer of film.

[0075] Specifically, during the process of adjusting the distance between the two first guide wheels 2323, the two first threaded blocks 2325 synchronously adjust the distance between the two groove tracks 2421 and the two pressure wheels 2424 through the second connecting rod 2422, so that the strip grooves pre-pressed on the surface of the first-layer film can correspond to the positions of the two groups of resilient strips. When the first-layer film advances to the flat plate 2411, the first-layer film is located on the two groove tracks 2421 and the top wheel 2414. The first hydraulic component 2423 drives the pressure wheel 2424 and the pressure rod 2425 to synchronously descend into the groove track 2421. The pressure wheel 2424 pre-presses the strip grooves on the surface of the first-layer film, causing the first-layer film to be laterally pulled to both sides. The first-layer film presses down the top wheel 2414, and the pressure rod 2425 and the groove track 2421 cooperate to press and maintain the shape of the pre-pressed strip grooves on the surface of the first-layer film.

[0076] Further, as Figures 6 - 8 shown, the shaping unit 243 includes a second cross bar 2431 arranged on the frame 1, two groups of second sliding columns 2432 symmetrically and slidably arranged on the second cross bar 2431, a first cam 2433 rotatably arranged on the second sliding column 2432 and used for pressing the grooves of the first-layer film, a third connecting rod 2434 arranged between the second sliding column 2432 and the first sliding column 2322, a second sliding hole opened on the frame 1, a second sliding block slidably arranged on the second sliding hole, a third cross bar 2435 rotatably arranged on the second sliding block, two groups of third sliding columns 2436 symmetrically and slidably arranged on the third cross bar 2435, and a first concave cam 2437 rotatably arranged on the third sliding column 2436 and used for cooperating with the first cam 2433 to maintain the shape of the grooves of the first-layer film;

[0077] It should be noted that there are two or more shaping units 243, which can change the advancing direction during the process of conveying the first-layer film with grooves. The two or more shaping units 243 synchronously adjust the positions of the first cam 2433 and the first concave cam 2437 through the fourth connecting rod to adapt to the groove positions of the first-layer film.

[0078] In this embodiment, by arranging the shaping unit 243, the shape of the strip grooves on the surface of the first-layer film can be maintained during the process of conveying the first-layer film with grooves.

[0079] Specifically, manually adjust the second slider to move towards the second crossbar 2431, so that the first cam 2437 on the third crossbar 2435 cooperates with the first cam 2433 on the second crossbar 2431. During the process of adjusting the distance between the two first guide wheels 2323, the first sliding column 2322 drives the second sliding column 2432 to move synchronously on the second crossbar 2431 through the third crossbar 2435. The second sliding column 2432 drives the first cam 2437 to move synchronously on the third crossbar 2435 through the first cam 2433, so that the first cam 2437 and the first cam 2433 can clamp the pre-pressing strip grooves with different distances on the first layer of film.

[0080] Further, as Figure 5 and Figures 8 - 10 shown, the composite mechanism 3 includes a first bonding component 31 disposed on the frame 1 and used for bonding and laminating the chip carrier film and two groups of resilient strips on the surface of the first layer of film, and a second bonding component 32 disposed on the frame 1 and used for bonding and laminating the second layer of film on the surface of the first layer of film;

[0081] The first bonding component 31 includes a first glue spraying unit 311 disposed on the frame 1 and used for spraying glue on the surface of the first layer of film after pressing the grooves, two groups of first pressing and bonding rollers 312 rotatably disposed on the frame 1, and a first annular groove opened on the first pressing and bonding roller 312 and used for accommodating the resilient strips;

[0082] The second bonding component 32 includes a second glue spraying unit 321 disposed on the frame 1 and used for spraying glue on the surface of the second layer of film, two groups of second pressing and bonding rollers 322 rotatably disposed on the frame 1, a second annular groove opened on the second pressing and bonding roller 322 and used for accommodating the resilient strips, and a pressing wheel 323 disposed on the frame 1 and used for pressing down the middle part of the second layer of film;

[0083] It should be noted that both the first glue spraying unit 311 and the second glue spraying unit 321 adopt existing glue spraying equipment;

[0084] It is worth mentioning that according to the different distances between the two resilient strips, the specifications of the first pressing and bonding roller 312 and the second pressing and bonding roller 322 can be replaced, that is, the positions of the first annular groove on the first pressing and bonding roller 312 and the second annular groove on the second pressing and bonding roller 322 are adjusted;

[0085] It also needs to be explained that the function of the pressing wheel 323 is the same as that of the top wheel 2414, so that the middle part of the second layer of film is pushed up to form a ridge, leaving space for the second layer of film to bond and wrap the resilient strips, and avoiding transverse tearing of the second layer of film.

[0086] In this embodiment, by the cooperation of the first bonding assembly 31 and the second bonding assembly 32 provided, the chip carrier film and two groups of resilient strips can be bonded and compounded on the surface of the first laminating film first, and then the second laminating film can be bonded and compounded on the surface of the first laminating film.

[0087] Specifically, the first glue spraying unit 311 sprays glue on the surface of the first laminating film after being grooved. The first annular grooves of the two first pressure bonding rollers 312 are respectively matched with the strip grooves of the resilient strip and the first laminating film, and the chip carrier film and two groups of resilient strips are bonded and compounded on the surface of the first laminating film. The second glue spraying unit 321 sprays glue on the surface of the second laminating film after being divided. The abutting wheel 323 pushes the middle part of the second laminating film downward to form a ridge, and the second annular groove on the second pressure bonding roller 322 presses and wraps the second laminating film on the resilient strip, and then the second laminating film is bonded and compounded on the surface of the first laminating film.

[0088] Furthermore, as Figure 4 and Figure 11 shown, the slitting mechanism 4 includes a slitting frame 41 arranged on the frame 1, two groups of slitting rollers 42 rotatably arranged inside the slitting frame 41, two groups of circular knives 43 arranged on the slitting rollers 42, a cutting knife arranged on the slitting rollers 42 and located between the two circular knives 43, and a receiving box 44 arranged on the frame 1 and used for collecting the electronic tags.

[0089] In this embodiment, by the slitting mechanism 4 provided, the composite intermediate product can be slit into electronic tags of the same specification.

[0090] Specifically, the composite intermediate product passes through the two slitting rollers 42. The circular knives 43 on the slitting rollers 42 cut the edges, and the cutting knife transversely cuts the resilient strip. The slit electronic tags fall into the receiving box 44 for the same collection.

[0091] Furthermore, as Figure 4 and Figures 12 - 17 shown, the rejection assembly 51 includes a film tearing unit 511 arranged on the frame 1 and used for tearing the laminating film adhered to the surface of the resilient strip waste, and a punching unit 512 arranged on the film tearing unit 511 and used for ejecting the resilient strip waste.

[0092] The film tearing unit 511 includes a mounting plate 5111 provided on the frame 1, a first conveyor belt 5113 and a second conveyor belt 5114 rotatably provided on the mounting plate 5111 through guide rollers 5112 and used for clamping and conveying the waste film, a plurality of groups of partition plates 5115 provided on the first conveyor belt 5113, a clamping cavity formed between two adjacent partition plates 5115 for accommodating the transverse part of the waste film, two groups of first through pipes 5116 penetrating and vertically provided on the first conveyor belt 5113 and located inside the clamping cavity, a first vacuum suction cup provided at one end of the first through pipe 5116, a first connecting plate 5117 provided between the two first through pipes 5116, a first elastic member provided between the first connecting plate 5117 and the first conveyor belt 5113, a first limiting track 5118 provided on the mounting plate 5111 and used for driving the first connecting plate 5117 to drive the first vacuum suction cup to descend through the first through pipe 5116, a plurality of groups of clamping grooves 5119 provided on the second conveyor belt 5114 and matching with two adjacent partition plates 5115, a resisting strip 51191 provided inside the clamping groove 5119 and matching with the inside of the clamping cavity, two groups of second through pipes 51192 penetrating and vertically provided on the second conveyor belt 5114 and located inside the clamping groove 5119, a second vacuum suction cup provided at one end of the second through pipe 51192, a second connecting plate 51193 provided between the two second through pipes 51192, a second elastic member provided between the second connecting plate 51193 and the second conveyor belt 5114, and a second limiting track 51194 provided on the mounting plate 5111 and used for driving the second connecting plate 51193 to drive the second vacuum suction cup to ascend through the second through pipe 51192;

[0093] It should be noted that both the first vacuum suction cup and the second vacuum suction cup are connected to an existing vacuum generator through hoses;

[0094] The punching-out unit 512 includes two sets of avoidance cavities 5121 formed on the second conveyor belt 5114 and located on both sides of the clamping groove 5119, a punching hole that is communicatively arranged between the two avoidance cavities 5121 and penetrates through the two partition plates 5115, a third through pipe 5122 that penetrates and is vertically arranged on the second conveyor belt 5114 and is located inside one of the avoidance cavities 5121, an inclined rod 5123 hinged to the lower end of the third through pipe 5122, a punching rod 5124 hinged to one end of the inclined rod 5123 and slidably matched with the inside of the punching hole, a third connecting plate 5125 arranged on the third through pipe 5122, a third elastic member 5126 arranged between the third connecting plate 5125 and the second conveyor belt 5114, a third limiting track 5127 arranged on the mounting plate 5111 and used to drive the third connecting plate 5125 to descend, and a material-transfer cavity 5128 formed on the first conveyor belt 5113 and matched with the other avoidance cavity 5121;

[0095] It is worth mentioning that a waste box is arranged on the frame 1, and the waste box is located below the first conveyor belt 5113 and is used to collect the waste of the tough strips after rejection. The collected waste of the tough strips can be recycled and reused.

[0096] In this embodiment, through the cooperation of the rejection assembly 51 and the winding assembly 52, on the one hand, the waste of the tough strips can be automatically separated from the waste of the coated film, classified and recycled, and can be reused repeatedly, reducing the production cost; on the other hand, the waste of the coated film can be evenly wound, avoiding the uneven thickness of the wound waste of the coated film and easily generating fluffy deformation, reducing the space occupied by the wound waste of the coated film, and preventing the frequent replacement of the wound waste of the coated film.

[0097] Specifically, the first conveyor belt 5113 and the second conveyor belt 5114 cooperate to synchronously convey the waste film with the transverse part of the waste film located in the clamping cavity. The partition 5115 on the first conveyor belt 5113 cooperates with the clamping groove 5119 of the second conveyor belt 5114, and the abutting strip 51191 of the clamping groove 5119 cooperates with the clamping cavity, so that the abutting strip 51191 presses the transverse part of the waste film except for the waste strip of the toughness strip into the clamping cavity. At the same time, the first vacuum sucker of the first through pipe 5116 sucks the lower layer of the waste film of the toughness strip waste, and the second vacuum sucker of the second through pipe 51192 sucks the upper layer of the waste film of the toughness strip waste. Then, after the first through pipe 5116 passes through the position of the first limit track 5118, the first limit track 5118 drives the first link plate 5117 to descend through the first through pipe 5116 with the first vacuum sucker. At the same time, the second limit track 51194 drives the second link plate 51193 to ascend through the second through pipe 51192 with the second vacuum sucker, so as to tear the upper and lower layers of the waste film of the toughness strip waste; Then, after the third through pipe 5122 of the punching unit 512 passes through the position of the third limit track 5127, the third limit track 5127 drives the third link plate 5125 to descend with the third through pipe 5122, and the third through pipe 5122 drives the punching rod 5124 to move horizontally through the inclined rod 5123, so that the punching rod 5124 punches the toughness strip waste after tearing the waste film into another avoidance cavity 5121. The toughness strip waste in the avoidance cavity 5121 falls into the transfer cavity 5128 on the first conveyor belt 5113. Then, when the third through pipe 5122 first disengages from the position of the third limit track 5127, the third elastic member 5126 drives the punching rod 5124 to move horizontally and reset. Then, when the first through pipe 5116 disengages from the position of the first limit track 5118, the first vacuum sucker ascends and resets. At the same time, when the second through pipe 51192 disengages from the position of the second limit track 51194, the second vacuum sucker descends and resets. Finally, as the first conveyor belt 5113 rotates, the opening end of the transfer cavity 5128 on the first conveyor belt 5113 faces downward, so that the toughness strip waste in the transfer cavity 5128 falls into the waste box.

[0098] Further, as Figure 4 and Figure 18 shown, the winding assembly 52 includes a winding roller 521 rotatably arranged on the frame 1 and working synchronously with the first conveyor belt 5113 by means of belt and pulley transmission, and a winding unit 522 arranged on the frame 1 and used for intermittently winding the longitudinal part of the waste film.

[0099] The folding unit 522 includes an eccentric wheel 5221 rotatably arranged on the frame 1 and synchronously operating with the winding roller 521 through the transmission of a belt and a pulley, a lifting groove 5222 formed on the frame 1, a frame 5223 slidably arranged on the lifting groove 5222, a pull rod 5224 hinged on the frame 5223 and having its upper end hinged to the eccentric wheel 5221, a second bidirectional threaded rod 5225 rotatably arranged inside the frame 5223, two second threaded blocks 5226 threadedly arranged on the second bidirectional threaded rod 5225, a folding rod 5227 arranged on the second threaded block 5226, a gear 5228 fixedly arranged at the end of the second bidirectional threaded rod 5225, and a rack 5229 arranged on the frame 1 and used to drive the gear 5228;

[0100] It should be noted that regardless of whether the frame 5223 rises or falls, the two folding rods 5227 can always be located on both sides of the waste plastic film.

[0101] In this embodiment, by arranging the winding assembly 52, the waste plastic film can be evenly wound, ensuring that the wound waste plastic film roll has the same thickness.

[0102] Specifically, during the process of the winding roller 521 winding the waste plastic film, the winding roller 521 drives the eccentric wheel 5221 to rotate through the transmission of a belt and a pulley. The eccentric wheel 5221 drives the frame 5223 to rise and fall repeatedly through the pull rod 5224. During the rising and falling process of the frame 5223, the rack 5229 drives the second bidirectional threaded rod 5225 to rotate through the gear 5228. The second bidirectional threaded rod 5225 drives the two folding rods 5227 to approach and move away from each other repeatedly through the second threaded blocks 5226, so that the two folding rods 5227 gradually gather the two sides of the waste plastic film towards the middle or spread them to both sides, enabling the winding roller 521 to evenly wind the waste plastic film.
