Description

Technical Field

[0001] The present invention relates to the technical field of acousto-magnetic anti-theft technology, and particularly relates to a method and system for processing a bias wire of an acousto-magnetic anti-theft label. Background Art

[0002] Acousto-magnetic anti-theft labels are commonly used commodity anti-theft technologies. An acousto-magnetic anti-theft label is fixed or pasted on a commodity. When the commodity passes through a detection system, unauthorized commodities can be effectively identified.

[0003] The bias pieces of the existing acousto-magnetic anti-theft labels on the market are rectangular flat materials, which are made by slitting and cutting cold-rolled alloy steel strips. The width of the bias piece is 3.0 mm to 6.0 mm, and the thickness is 0.05 mm to 0.1 mm. In label production, the bias pieces are placed in a fixed box in advance, and then single pieces are sucked out by a vacuum chuck and transferred and pasted on the bottom of the label or double-sided tape for combination.

[0004] The bias pieces of the existing acousto-magnetic anti-theft labels can be made by vacuum suction and pasting. This method can only produce traditional sheet bias pieces and cannot work on filamentous bias wires. For example, a Chinese invention patent with the application publication number CN116665389A and the application publication date of August 29, 2023 discloses an acousto-magnetic anti-theft label, which includes a resonance piece and at least one bias wire for providing a bias magnetic field for the resonance piece; the acousto-magnetic anti-theft label further includes a box body, a cover film, a box cover and double-sided tape. One or more resonance pieces that match the box body in size and are stacked on top of each other are placed in the cavity of the box body. The bias wire uses a low-cost metal wire to make a filamentous bias element by a cold drawing process.

[0005] In summary, the acousto-magnetic anti-theft label cannot use the vacuum suction and pasting method to batch process the bias wire, the processing difficulty of the bias wire is large, the assembly accuracy of the bias wire is low, and the problem of large-scale production of the bias wire and its label of the acousto-magnetic anti-theft label cannot be achieved. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a method and system for processing a bias wire of an acousto-magnetic anti-theft label, so as to solve the problems that the acousto-magnetic anti-theft label cannot use the vacuum suction and pasting method to batch process the bias wire, the processing difficulty of the bias wire is large, the assembly accuracy of the bias wire is low, and the large-scale production of the bias wire and its label of the acousto-magnetic anti-theft label cannot be achieved.

[0007] The technical solution of the method for processing a bias wire of the acousto-magnetic anti-theft label of the present invention is as follows:

[0008] A method for processing a bias wire of an acousto-magnetic anti-theft label includes the following steps:

[0009] S1. Feed at least two groups of wire materials synchronously; first, straighten the wire materials through a straightener, or if the wire materials are flat wires, omit the straightening process;

[0010] S2. At least two groups of wire materials penetrate the linear guide grooves in parallel and enter the cutting tool station;

[0011] S3. At the cutting tool station, the wire materials extend to the wire outlet side of the first cutting tool mechanism, and use the first cutting tool to cut at least two groups of wire materials simultaneously to obtain offset wire products of a set length. At least two groups of offset wire products are pressed against the adhesive surface of the double-sided tape and are wound and moved along with the double-sided tape;

[0012] S4. Unwind the double-sided tape with the offset wire products pasted on it, pull the double-sided tape horizontally and place it at the paving station. The double-sided tape is located above the whole plate of semi-finished product labels;

[0013] S5. At the paving station, the offset wire products of the double-sided tape correspond to the resonance pieces of the whole plate of semi-finished product labels. Paste the double-sided tape on the whole plate of semi-finished product labels and use the second cutting tool mechanism to cut the double-sided tape into segments.

[0014] Further, in step S2, when at least two groups of wire materials enter the cutting tool station, position at least two groups of wire materials through the concave-convex limiting tooling.

[0015] Further, in step S3, when cutting, use the pressing block on the back of the first cutting tool to press at least two groups of offset wire products.

[0016] Further, the length of the offset wire product is any size from 20 mm to 40 mm;

[0017] The wire material is round wire, and the cross-sectional area of the offset wire product is any size from 0.03 to 0.79 mm 2 ; or, the wire material is made by flattening or drawing round wire, and the cross-sectional area of the flat offset wire product is any size from 0.03 to 7.1 mm 2 .

[0018] Further, in step S4, pass the double-sided tape with the offset wire products pasted on it through the fixing fixture and enter the paving station. When the pulling chuck tightens the double-sided tape, the fixing fixture loosens and allows the double-sided tape to be pulled out. When the length of the pulled-out double-sided tape is equal to the length of the whole plate of semi-finished product labels, clamp the double-sided tape through the fixing fixture.

[0019] Further, in step S5, control the pulling chuck and the fixing fixture to move down synchronously, so that the adhesive surface of the double-sided tape is pasted on the whole plate of semi-finished product labels, and automatically cut the double-sided tape through the telescopic movement of the blades of the second cutting tool mechanism.

[0020] The technical solution of the offset wire processing system for the acousto-magnetic anti-theft label of the present invention is as follows:

[0021] A system based on the offset wire processing method of the above-mentioned acoustic magnetic anti-theft tag includes a wire correction mechanism, a first cutter mechanism, a feeding mechanism, a tag conveying mechanism, a chuck mechanism, and a second cutter mechanism;

[0022] The wire straightening mechanism, the first cutting mechanism and the feeding mechanism are arranged in sequence along the extension direction of the wire, and a linear guide groove is provided between the wire straightening mechanism and the first cutting mechanism, and the linear guide groove is used to cooperate with at least two groups of wire guides;

[0023] The wire outlet side of the first cutting mechanism is provided with a blanking area, the feeding mechanism is used for winding or unwinding the double-sided adhesive tape, and the blanking area is arranged to overlap with the double-sided adhesive tape, so that the cut bias wire finished product is pressed against the adhesive surface of the double-sided adhesive tape;

[0024] The label conveying mechanism is used to convey a whole page of semi-finished labels, and the clamping mechanism and the second cutting mechanism are arranged relatively on the outside of the label conveying mechanism;

[0025] The clamp mechanism is provided with a material pulling clamp for clamping and pulling the double-sided adhesive tape. When the double-sided adhesive tape with the offset thread finished product and the whole page of semi-finished labels are laid, the second cutting mechanism cuts the double-sided adhesive tape into sections.

[0026] Furthermore, a concave-convex limiting tool is provided on the wire feeding side of the first cutting mechanism, and at least two limiting grooves are opened on the concave-convex limiting tool. The limiting grooves are used to cooperate with the wire gap, and the openings of the limiting grooves are arranged upward to position the wire when cutting.

[0027] Furthermore, the first cutter mechanism includes a first cutter, a first driver and a pressure block, the first driver is transmission-connected to the first cutter, the driving direction of the first driver is arranged vertically, the first cutter is arranged perpendicular to the length direction of the wire, the pressure block is fixedly installed on the back of the first cutter, and the pressure block is used to press and cooperate with the double-sided tape.

[0028] Furthermore, it also includes a fixing fixture, which is arranged outside the label conveying mechanism, and the fixing fixture is arranged opposite to the clamping mechanism;

[0029] The fixing fixture includes a support, a clamp, a support driver and a clamp driver. The support driver is connected to the support for driving the support to move up and down so that the double-sided tape can be laid on the entire page of semi-finished labels; the clamp driver is connected to the clamp for driving the clamp to move up and down to clamp or release the double-sided tape.

[0030] A method and system for processing the bias wire of an acousto-magnetic anti-theft label according to the present invention has the following beneficial effects compared with the prior art: The bias wire processing system of the acousto-magnetic anti-theft label adopts the design forms of a wire straightening mechanism, a first cutting mechanism, a feeding mechanism, a label conveying mechanism, a chuck mechanism, and a second cutting mechanism. After the wire coil is unloaded, the wire is straightened by the wire straightening mechanism, and the straightness of at least two groups of wires is improved through a straightener. Or, if the wire is a flat wire, the straightening process is omitted. The at least two groups of straightened wires continue to feed through the linear guide groove, and the linear guide groove is in guiding cooperation with the at least two groups of wires to ensure that the wires can feed stably along a straight line, thereby improving the dimensional accuracy of the wire cutting by the first cutting mechanism.

[0031] Since a blanking area is provided on the wire outlet side of the first cutting mechanism, and the feeding structure winds / unwinds a double-sided adhesive, when at least two groups of wires enter the cutting station, the wires extend to the wire outlet side of the first cutting mechanism, and the first cutting mechanism is used to simultaneously cut off the parts of the at least two groups of wires extending to the outlet side, obtaining at least two groups of bias wire products with set lengths. The bias wire products are in the blanking area, and the blanking area coincides with the double-sided adhesive, ensuring that the cut bias wire products can be pressed on the adhesive surface of the double-sided adhesive and move with the double-sided adhesive during winding.

[0032] The label conveying mechanism conveys a full-page semi-finished label. The chuck mechanism and the second cutting mechanism are relatively arranged outside the label conveying mechanism. The feeding structure unwinds the double-sided adhesive with the bias wire products pasted on it, and the pulling chuck of the chuck mechanism is used to clamp and pull the double-sided adhesive, horizontally pulling the double-sided adhesive to the pasting station so that the double-sided adhesive is located above the full-page semi-finished label. At the pasting station, the bias wire products of the double-sided adhesive correspond to the resonance pieces of the full-page semi-finished label. Then, the double-sided adhesive is pasted on the full-page semi-finished label through the chuck mechanism. Finally, the second cutting mechanism cuts the double-sided adhesive into sections, obtaining a full-page acousto-magnetic anti-theft label product.

[0033] The method and system for processing the bias wire of the acousto-magnetic anti-theft label are designed with processes such as wire straightening, wire cutting, bias wire pressing, and double-sided adhesive pasting, which can process the bias wire in batches, ensure the processing quality and assembly accuracy of the bias wire, and realize the large-scale production of the bias wire and its label of the acousto-magnetic anti-theft label.

Detailed implementation manners

[0040] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0041] A method for processing the bias wire of an acousto-magnetic anti-theft label in this embodiment, as Figures 1 to 5 shown, includes the following steps:

[0042] S1. At least two groups of wires 10 are fed synchronously; first, the wires 10 are straightened by the straightener 11 to improve the straightness of at least two groups of wires 10 through the straightener 11, or, if the wire is a flat wire, the straightening treatment is omitted.

[0043] S2. At least two groups of wires 10 penetrate through the linear guide groove 13 in parallel and enter the cutting tool station. The at least two groups of straightened wires 10 continue to feed through the linear guide groove 13, and the linear guide groove 13 is in guiding cooperation with the at least two groups of wires 10 to ensure that the wires 10 can feed stably along a straight line, thereby improving the dimensional accuracy of the cutting of the wires 10 by the first cutting mechanism 2.

[0044] In step S2, when at least two groups of wire materials 10 enter the cutting tool station, the at least two groups of wire materials 10 are positioned by the concave-convex limiting tooling 22. The concave-convex limiting tooling 22 is arranged on the wire inlet side of the first cutting tool mechanism 2. The concave-convex limiting tooling 22 is provided with at least two limiting grooves. The limiting grooves are used for clearance fit with the wire materials 10, and the openings of the limiting grooves are arranged upward to position the wire materials 10 during cutting. The distance between at least two limiting grooves is equal to the set spacing of the offset wire finished products 12, ensuring the accurate distribution of the offset wire finished products 12 obtained by cutting on the double-sided tape 30, and further ensuring the accuracy of the offset wire pressing.

[0045] S3. At the cutting tool station, the wire materials 10 extend to the wire outlet side of the first cutting tool mechanism 2. The first cutting tool 20 is used to simultaneously cut at least two groups of wire materials 10 to obtain the offset wire finished products 12 of a set length. At least two groups of offset wire finished products 12 are pressed on the adhesive surface of the double-sided tape 30 and move with the double-sided tape 30 during winding.

[0046] In step S3, during cutting, the pressure block on the back of the first cutting tool 20 is used to press and paste at least two groups of offset wire finished products. The pressure block on the back of the first cutting tool 20 is used to press and paste the offset wire finished products 12 on the adhesive surface of the double-sided tape 30. The wire cutting and the offset wire pressing process are carried out synchronously, ensuring the pressing accuracy of the offset wire finished products 12. Among them, the length of the offset wire finished products 12 is any size from 20 mm to 40 mm. If the wire material is round wire, the cross-sectional area of the offset wire finished products 12 is any size from 0.03 to 0.79 mm 2 ; or, if the wire material is made by flattening or drawing a round wire, the cross-sectional area of the flat offset wire finished product is any size from 0.03 to 7.1 mm 2 of any size.

[0047] S4. The double-sided tape 30 with the offset wire finished products 12 pasted on it is unwound, and the double-sided tape 30 is horizontally pulled out and in the paving station. The double-sided tape 30 is located above the whole-page semi-finished label 40. In step S4, the double-sided tape 30 with the offset wire finished products 12 pasted on it enters the paving station through the fixed fixture. When the pulling chuck 50 tightens the double-sided tape 30, the fixed fixture loosens and the double-sided tape 30 is pulled out. When the length of the pulled-out double-sided tape 30 is equal to the length of the whole-page semi-finished label 40, the double-sided tape 30 is clamped by the fixed fixture.

[0048] S5. At the paving station, the offset wire of the double-sided tape 30 corresponds to the resonance piece of the whole-page semi-finished label 40. The double-sided tape 30 is paved on the whole-page semi-finished label 40, and the double-sided tape 30 is cut into sections by the second cutting tool mechanism 6. In step S5, the pulling chuck 50 and the fixed fixture are controlled to move down synchronously, so that the adhesive surface of the double-sided tape 30 is paved on the whole-page semi-finished label 40, and the double-sided tape 30 is automatically cut by the telescopic action of the blade of the second cutting tool mechanism.

[0049] The processing method of the bias wire of the acousto-magnetic anti-theft label is designed with processes such as wire straightening, wire cutting, bias wire pressing and double-sided tape paving, etc., which can process the bias wire in batches, ensure the processing quality and assembly accuracy of the bias wire, and realize the large-scale production of the bias wire and its label of the acousto-magnetic anti-theft label.

[0050] In this embodiment, a bias wire processing system for an acousto-magnetic anti-theft label is as Figures 1 to 4 shown. The bias wire processing system of the acousto-magnetic anti-theft label includes a wire straightening mechanism 1, a first cutting knife mechanism 2, a feeding mechanism 3, a label conveying mechanism 4, a chuck mechanism 5 and a second cutting knife mechanism 6; the wire straightening mechanism 1, the first cutting knife mechanism 2 and the feeding mechanism 3 are arranged in sequence along the extending direction of the wire 10. There is a linear guiding groove 13 between the wire straightening mechanism 1 and the first cutting knife mechanism 2, and the linear guiding groove 13 is used for guiding and cooperating with at least two groups of wires.

[0051] A blanking area 21 is arranged on the wire outlet side of the first cutting knife mechanism 2. The feeding mechanism 3 is used for winding or unwinding the double-sided tape 30. The blanking area 21 coincides with the double-sided tape 30, so that the cut bias wire finished product 12 is pressed on the adhesive surface of the double-sided tape 30. The label conveying mechanism 4 is used for conveying the whole plate of semi-finished labels 40. The chuck mechanism 5 and the second cutting knife mechanism 6 are oppositely arranged on the outer side of the label conveying mechanism 4; the chuck mechanism 5 is provided with a pulling chuck 50 for clamping and pulling the double-sided tape 30. When the double-sided tape 30 with the bias wire finished product 12 pasted on it is paved with the whole plate of semi-finished labels 40, the second cutting knife mechanism 6 cuts the double-sided tape 30 into sections.

[0052] The bias wire processing system of the acousto-magnetic anti-theft label adopts the design forms of the wire straightening mechanism 1, the first cutting knife mechanism 2, the feeding mechanism 3, the label conveying mechanism 4, the chuck mechanism 5 and the second cutting knife mechanism 6. After the wire coil is unwound, it is straightened by the wire straightening mechanism 1, and the straightness of at least two groups of wires 10 is improved through the straightener 11; the at least two groups of straightened wires 10 continue to feed through the linear guiding groove 13, and the linear guiding groove 13 guides and cooperates with the at least two groups of wires 10 to ensure that the wires 10 can feed stably along a straight line direction, thereby improving the dimensional accuracy of the first cutting knife mechanism 2 for cutting the wires 10.

[0053] Since a blanking area 21 is arranged on the wire outlet side of the first cutting knife mechanism 2 and the feeding structure 3 winds / unwinds the double-sided tape 30, when at least two groups of wires 10 enter the cutting knife station, the wires 10 extend to the wire outlet side of the first cutting knife mechanism 2, and the part of at least two groups of wires 10 extending to the outlet side is simultaneously cut by the first cutting knife mechanism 2 to obtain at least two groups of bias wire finished products 12 with set lengths. The bias wire finished products 12 are in the blanking area 21, and the blanking area 21 coincides with the double-sided tape 30, ensuring that the cut bias wire finished products 12 can be pressed on the adhesive surface of the double-sided tape 30 and move with the double-sided tape 30 during winding.

[0054] The label conveying mechanism 4 conveys a whole page of semi-finished labels 40, the chuck mechanism 5 and the second cutter mechanism 6 are relatively arranged on the outside of the label conveying mechanism 4, the feeding structure 3 unwinds the double-sided adhesive tape 30 with the offset wire finished product 12 attached thereto, and the double-sided adhesive tape 30 is clamped and pulled by the material pulling chuck 50 of the chuck mechanism 5, so that the double-sided adhesive tape 30 is horizontally pulled out to the laying station, so that the double-sided adhesive tape 30 is located above the whole page of semi-finished labels 40. At the laying station, the offset wire finished product 12 of the double-sided adhesive tape 30 corresponds to the resonance sheet of the whole page of semi-finished labels 40, and the double-sided adhesive tape 30 is laid on the whole page of semi-finished labels 40 through the chuck mechanism 5, and finally the second cutter mechanism 6 cuts the double-sided adhesive tape 30 into segments, and a whole page of acoustic magnetic anti-theft labels is obtained.

[0055] The bias wire processing system of the acoustic-magnetic anti-theft label is designed with processes such as wire straightening, wire cutting, bias wire pressing and double-sided tape laying. It can process the bias wire in batches, ensure the processing quality and assembly accuracy of the bias wire, and realize the large-scale production of the bias wire and the label of the acoustic-magnetic anti-theft label.

[0056] In this embodiment, a concave and convex limiting tool 22 is provided on the wire feeding side of the first cutting mechanism 2. Figure 3 As shown, at least two limiting grooves are provided on the concave-convex limiting tool 22, and the limiting grooves are used to match the gap with the wire 10, and the opening of the limiting grooves is arranged upward to position the wire 10 when cutting. The distance between at least two limiting grooves is equal to the set spacing of the offset wire finished product 12, ensuring that the offset wire finished product 12 obtained by cutting is accurately distributed on the double-sided adhesive 30, thereby ensuring the accuracy of the offset wire pressing.

[0057] As a further preferred embodiment, the first cutter mechanism 2 includes a first cutter 20, a first driver 23, a pressure block and a tool holder structure 24. The first driver 23 is connected to the first cutter 20 in a transmission manner. The driving direction of the first driver 23 is arranged vertically. The first cutter 20 is arranged perpendicular to the length direction of the wire 10. The pressure block is fixedly mounted on the back of the first cutter 20 (not shown in the figure), and the pressure block is used to press and match with the double-sided adhesive tape 30. The first driver 23 is fixedly mounted on the tool holder structure 24. The first driver 23 is a hydraulic cylinder, a cylinder or an electric push rod. The first cutter 20 is driven up and down by the first driver 23, and at least two groups of wires 10 can be cut simultaneously. At the same time, the pressure block on the back of the first cutter 20 is used to press the offset wire product 12 on the adhesive surface of the double-sided adhesive tape 30. The wire cutting and offset wire pressing processes are performed simultaneously, ensuring the accuracy of pressing the offset wire product 12.

[0058] It should be noted that the feeding mechanism 3 includes a double-sided adhesive feeding roll 31, a double-sided adhesive receiving roll 32, and a bias wire and double-sided adhesive feeding roll 33. A double-sided adhesive 30 is arranged between the double-sided adhesive feeding roll 31 and the double-sided adhesive receiving roll 32. Part of the adhesive surface of the double-sided adhesive 30 overlaps with the blanking area 21 of the first cutting mechanism 2, so that the cut bias wire finished product 12 can be accurately pressed on the adhesive surface of the double-sided adhesive 30, and the winding work is completed with the double-sided adhesive receiving roll 32. The bias wire and double-sided adhesive feeding roll 33 are arranged opposite to the chuck mechanism 5, and are used to lay the double-sided adhesive 30 with the bias wire finished product 12 on the full-page semi-finished label 40. In addition, the surface of the pulling chuck 50 is provided with a non-stick material, for example: the surface is coated with Teflon, or is made of ceramics and other materials.

[0059] In addition, the bias wire processing system of the acoustic magnetic anti-theft label also includes a fixed clamp (not shown in the figure), which is arranged on the outside of the label conveying mechanism 4, and the fixed clamp is arranged opposite to the clamping mechanism 5. The fixed clamp includes a support, a clamp, a support driver and a clamp driver. The support driver is connected to the support in a transmission manner, and is used to drive the support to move up and down so that the double-sided tape 30 can be laid on the entire semi-finished label 40; the clamp driver is connected to the clamp in a transmission manner, and is used to drive the clamp to move up and down to clamp or loosen the double-sided tape 30.

[0060] The loosening and clamping actions of the fixing clamp work synchronously with the material pulling clamp 50 of the clamp mechanism 5, so that the double-sided adhesive tape 30 can be smoothly pulled out horizontally, and the double-sided adhesive tape 30 can be clamped to maintain a set length, and the fixing clamp and the clamp mechanism 5 can move downward at the same time, so that the double-sided adhesive tape 30 is laid on the whole page of semi-finished labels 40. Finally, the second cutting mechanism 6 cuts the double-sided adhesive tape 30 into segments along the edge of the whole page of semi-finished labels 40, and the whole page of finished acoustic and magnetic anti-theft labels can be obtained.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
