Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the following detailed description is provided with reference to the accompanying drawings:
referring to fig. 1, 2, 3 and 4, in the preferred embodiment of the present invention, an LM4 rf tag module of a precut composite magnetic conductive sheet is disposed on a tag module carrier tape 10, and the LM4 rf tag module includes an LM4 tag module body 1 and a precut composite magnetic conductive sheet 2. Two rows of label modules are arranged on the label module carrier tape 10, and each row of label modules comprises a plurality of LM4 label module bodies 1 which are sequentially arranged along the length direction of the label module carrier tape 10; the front side of each LM4 label module body 1 is provided with a UV package 12 for encapsulating a chip and a gold wire.
Each LM4 label module body 1 is all rectangular, and LM4 label module body 1's minor face is parallel with the width direction of label module carrier tape 10, and LM4 label module body 1's long limit is parallel with the length direction of label module carrier tape 10.
The front side of each LM4 label module body 1 is provided with a precut composite magnetic conductive sheet 2, and the overall dimension of the precut composite magnetic conductive sheet 2 is matched with the overall dimension of the LM4 label module body 1; each precut composite magnetic conductive sheet 2 comprises an inner-layer adhesive tape 21, a magnetic conductive tape 22, an outer-layer adhesive tape 23 and release paper 24 which are sequentially arranged from inside to outside; the inner-layer adhesive tape 21 is provided with a packaging area mounting through hole 25, and the packaging area mounting through hole 25 is matched with the UV package 12 on the corresponding LM4 label module body 1; the front surface of the LM4 label module body 1 is adhered to one surface of the magnetic conductive tape 22 by the inner layer adhesive tape 21, and the UV packages 12 on the LM4 label module body 1 are inserted into the corresponding package region mounting through holes 25. The other side of the tape guide 22 is bonded to a release paper 24 by an outer layer of adhesive tape 23.
The utility model discloses a LM4 radio frequency label module of compound magnetic conductive plate cuts in advance, magnetic conduction area 22 has solved the radio frequency communication that appears in the use and has absorbed the problem of unable normal work by metal object, when using, only need along the border of compound magnetic conductive plate 2 cuts in advance, cut LM4 radio frequency label module from label module carrier band 10, detach from type paper 24 on the outer adhesive tape 23, directly attached just can normally work at the metal surface, it is convenient fast to use, and can ensure not to damage chip and coil (spun gold) in the label region promptly. Is particularly suitable for being directly attached to the surfaces of a metal can and a metal barrel with an arc shape.
The utility model discloses a LM4 radio frequency label module of compound magnetic conductive plate cuts in advance, the upper and lower limit of label module carrier band 10 is provided with a plurality of conveying perforation 13 respectively, and three conveying perforation 13 on the upper and lower edge of every LM4 label module carrier band 10 of the upper and lower long limit one-to-one of every LM4 label module body 1, like this, every LM4 label module body 1 is fixed a position by 6 conveying perforation 13. The width w of the label module carrier tape 10 is 35mm, and the LM4 radio frequency label module is attached to the label module carrier tape 10 with the single-row double-perforation interval and the width of 35 mm. Therefore, the mechanical/automatic mounting can be directly carried out on the label module production line by using the conveying tooth holes 13 on the two sides. And simultaneously, the end user can conveniently carry out conveying and punching processing on the automatic production line by using the standard conveying perforation 13 on the 35mm label module carrier tape 10.
The utility model discloses a LM4 radio frequency label module of compound magnetic conduction piece cuts in advance has certain requirement to the thickness of inlayer adhesive tape 21, and the thickness of inlayer adhesive tape 21 needs to be greater than the thickness of UV encapsulation 12 on LM4 label module body 1. This is because the front (functional surface) of the LM4 tag module body 11 is first to be soldered with a radio frequency IC chip, and two gold wires are needed to be soldered between the IC chip and the solder points at the two ends of the radio frequency antenna on the tag module carrier tape. After the two gold wires need to be interconnected with two welding spots on the chip and an antenna welding end, the chip of the label module and the two gold wires need to be packaged by ultraviolet curing epoxy, which is called UV packaging for short 12. The UV packaging layer has certain requirements on thickness and area in the production process. The packaging thickness of the common UV epoxy on the label module carrier tape is less than 0.5mm, and the packaging area is within 4mm of the diameter. In order to ensure that the packaged finished label module can be flatly adhered to the plane of the radio frequency magnetic conductive sheet, a through hole slightly larger than the chip packaging area, namely a packaging area mounting through hole 25, needs to be punched in advance in the area of the inner layer adhesive tape 21 corresponding to the UV packaging area before the inner layer adhesive tape is compounded with the magnetic conductive tape. Typically the package area mounting through holes 25 have a diameter of 5mm, i.e. a dimension slightly larger than 4mm for the UV package. And, the thickness a of the inner layer adhesive tape 21 should be 0.5mm or more. The thickness a of the inner layer adhesive tape 21 is generally 0.8 to 5.0 mm. Thus, the label module can be attached to a metal surface smoothly during use. And the situation that the UV packaging area protrudes on the surface to be attached with metal due to too small opening diameter of the packaging area mounting through hole 25 or too thin inner layer adhesive tape 21 is avoided, and the protruding easily damages the chip and gold wire of the UV packaging, so that the performance of the label module is failed.
The utility model discloses a LM4 radio frequency label module of compound magnetic conduction piece cuts in advance, inner layer adhesive tape 21 and outer adhesive tape 23 itself can not contain any metal material. Acrylic double-sided adhesive tape of PET substrate is generally adopted, and adhesive tape of other non-metal substrates can also be adopted. The material and performance of the label module can be selected according to the use environment of the label module.
The utility model discloses a LM4 radio frequency label module of compound magnetic conductive plate cuts in advance adds man-hour, at first will cut encapsulation area mounting through hole 25 on the inlayer adhesive tape 21. The pitch of the package region mounting through holes 25 is determined by the pitch (9.50mm pitch) of the adjacent two transfer sprocket holes 13 on the label module carrier tape 10. And then compounding the inner-layer adhesive tape and the outer-layer adhesive tape with the magnetic tape, wherein the inner-layer adhesive tape 21 and the outer-layer adhesive tape 23 both adopt double-sided adhesive tapes with release paper. Thus, a set of combined parts of inner and outer adhesive tapes in a roll shape with release paper on both sides and a plastic-based magnetic tape sandwiched therebetween is formed. Then, precutting is performed according to the location of the package area mounting through hole 25 punched on the inner layer adhesive tape 21 and the relative position that the LM4 label module body occupies on the carrier tape. And then, after the release paper on the inner layer adhesive tape 21 is stripped, the precut composite magnetic conductive sheet 2 which is slightly larger than the overall dimension of the LM4 label module body 1 and is cut out by punching is adhered to the functional surface of the LM4 label module carrier tape. Because the position of the LM4 label module body 1 on the label module carrier tape 10 is precisely designed, we can occupy the carrier tape 2 conveying perforations 13(9.50mm spacing) and the carrier tape central symmetry arrangement according to the single-row LM4 label module body 1, the external dimension of the pre-cut compound magnetic conductive sheet 2 is slightly larger than the effective area of the antenna coil of the LM4 label module carrier tape (i.e. the dimension of the LM4 label module body 1), and it can conveniently and precisely use the automatic equipment to fix and paste. Before the double-layer adhesive tape/radio frequency magnetic conductive tape and the LM4 label module carrier tape are compounded, the overall dimension of the LM4 label module can be pre-cut on the compound adhesive tape/magnetic conductive tape in advance. The size of the precut composite magnetic conductive sheet 2 is 1-1.5 mm larger than that of the LM4 label module body 1, so that in the using process, each LM4 radio frequency label module can be directly punched or cut, and the coil of the label module can be ensured not to be damaged.
This pre-cutting has two requirements: first, the entire composite tape must be cut through, including the inner layer of adhesive tape 21, the magnetically permeable tape 22, the outer layer of adhesive tape 23, and the release paper 24. Before the antenna surface (LM4 label module body 1) adhered to the LM4 label module carrier tape 10 is adhered, the release paper on the inner layer adhesive tape is removed; secondly, the size of the precut composite magnetic conductive sheet 2 is slightly larger than the effective size of the actual pattern of the antenna of the LM4 label module body, but cannot be too large (usually slightly larger than the periphery of the antenna by 1-1.5 mm). Too large to connect with an adjacent LM4 tag module; but not too small, if the pre-cut size is too small, the antenna will be cut and the whole product will fail when the end user cuts or punches according to the LM4 size guided by the pre-cut pattern of the composite magnetic conductive sheet.
Although the back of the LM4 rf tag module is FR4 fiberglass cloth substrate, it is not identifiable from the outside surface by any graphics or indicia. However, a user can accurately position each tag module according to the physical size boundary of the pre-cut composite magnetic conductive sheet 2 on the functional surface (front surface) of the tag module carrier antenna/chip.
The utility model discloses a LM4 radio frequency label module of compound magnetic conductive plate cuts in advance, when end user department used, earlier along the compound magnetic conductive plate 2 that cuts in advance cut the profile with single LM4 label module die-cut out in advance. Then the release paper 24 at the outermost layer is stripped, so that the LM4 radio frequency label module can be attached to the surface of a metal object of a working object, and the label module can normally work on the metal surface.
Can be generally used on the arc surface of a metal can or a metal bottle or the non-groove-milling metal surface. It may be a vertical or horizontal mounting application. Because the utility model discloses a LM4 label module cuts in advance has clear and definite bellied physical interface, so automated production carries out very easily to can keep accurate overall dimension. So that it can be mounted flush on the plane of the metal workpiece to be tested.
This reality the utility model discloses a LM4 radio frequency label module of compound magnetic conductive plate cuts in advance because there is clear and definite protruding peripheral size interface, also provides very big convenience and flexibility for the manual occasion use of cuting of various utilization. Damage to the LM4 label module when die cut and sheared is also avoided due to the slightly enlarged active area of LM4 when pre-cut size design.
The utility model discloses a LM4 radio frequency label module of cutting compound magnetic conductive plate in advance can directly accomplish on the help of label module production line.
The utility model provides a generally when using, paste earlier magnetic conductive film and fix on the surface of metal, then attach label module on the magnetic conductive film first class operation complexity problem. The utility model discloses need not divide 2 times to paste magnetic film and label module, can use very conveniently and carry out the optional position at metal surface and paste.
To sum up, the utility model discloses a LM4 radio frequency label module of compound magnetic conductive plate cuts in advance, at the corresponding border region of LM4 label module body, pastes the compound magnetic conductive plate of precutting LM4 label module body profile, when end user uses, can conveniently cut out LM4 radio frequency label module from the label module carrier band directly perceivedly along the border of cutting compound magnetic conductive plate in advance.
