Description
METHOD AND APPARATUS FOR FIXING AN ACTIVE LABEL TO A PATCH AND UM PNEUMATIC Field of the Invention This invention relates to an apparatus and method for attaching an active label to a patch and a tire. More particularly, this invention establishes a method and apparatus for encapsulating an electronic device in a rigid material, mounting the device in a vulcanized rubber patch, and ligating the rubber patch to a vulcanized tire. BACKGROUND OF THE INVENTION tire engineering, such as wear, internal pressure and internal temperature, in order to reduce costs and maximize vehicle efficiency. Of course, it is advantageous to carry out this verification on tires of large trucks, which are expensive. From the prior art method of testing large truck tires they have included passive integrated circuits encapsulated in the tire body, or self-energized circuits that are placed external to the tire. Passive integrated circuits are based on capacitive coupling or inductive magnetic coupling to energize circuit r thereby providing circuit power from a remote source of the tire.
Self-energized circuits placed external to the tire are exposed to environmental damage such as bad weather, orange blossoms on the road and even vandalism. Recent engineering advances have allowed the installation of verification devices that have active integrated circuits inside the tire. Such a device is described in U.S. Patent No. 5,5562,787 issued to Koch et al. Entitled "Method of Monitoring Conditions of Vehicle Tires", hereby incorporated by reference. , and granted to the assignee of the present invention. These devices include a dedicated long-lived energized active circuit, miniature battery and at least one detector for sensing, optionally storing and transmitting real-time engineering conditions within the tire. These devices are capable of being programmed to remain in an active, but dormant condition, although they will automatically switch to an "awake" condition in response to an external signal or condition that exceeds predefined limits. One of the problems faced with these active devices is that they are delicate electronic devices that must operate in the harsh environment of a tire. In this way it is important to secure these devices in the tires, to minimize the effect of the arduous tire environment, while still allowing them to be exposed in an environment to allow accurate verification of engineering conditions for tire life. These previously active devices have been mounted on tires by first encapsulating the device or circuit containing energy in a material that forms a rigid or semi-rigid encapsulation with respect to the device, thereby inhibiting the effort of the device as a result of applied stresses. These materials have included compounds other than foam such as urethanes, epoxies, polyester-styrene resins, rigid rubber compositions and the like. The encapsulated device is then placed in a raw rubber material that forms a housing or is placed in a bag or cavity of raw rubber that becomes part of the tire. The encapsulated device is then permanently set in the rubber material during a subsequent vulcanization operation. The raw rubber material containing the encapsulated device can be assembled in the raw tire and then vulcanized with the tire. Alternatively, the raw patch containing the encapsulated device can be vulcanized separately and then fixed to a cured tire with a convenient adhesive. In any event, the delicate electronic components of the active label are exposed to high vulcanization temperatures that can adversely affect their performance or cut their life. Additionally, certain components of the device, such as the pressure detector or a thermistor, must remain open to the tire load under pressure. The flow of rubber that occurs during the vulcanization process can affect the openings in the tire cavity. As set forth in the U.S. Patent. No. 5,562,787, the opening in the tire cavity can remain open during the curing operations by placing a pin within the opening. While the methods and apparatus of U.S. Pat. No. 5,562,787, provide an acceptable method for assembling an active microcircuit in a tire cavity, an improved method and apparatus that increase the duration of the active microcircuit to the tire, are convenient. COMPENDIUM OF THE INVENTION According to the present invention, an improved method and apparatus for assembling an active electronic verification device in a tire cavity is described. The improved method and apparatus is increased to the duration of the electronic verification device by minimizing stress, strain, cyclic fatigue, vibration impact to which the electronic verification device is subjected when properly assembled in the tire. While the location of the device is an important factor in determining the duration of an electronic verification device located within a tire, it is also the manner in which the device is installed in the tire. A method for fastening within an tire an electronic verification device, for verifying at least one engineering condition of a tire, comprises the steps of encapsulating an electronic verification device by placing the electronic verification device in a mold having one with Pre-selected configuration, the pre-selected configuration includes at least one face having a high pattern and alternating recess to increase the surface area of the face. The mold is filled with an epoxy encapsulation material, such that the electronic verification device is encapsulated by the epoxy. The epoxy encapsulation material is cured to form a rigid label structure having a pre-selected configuration. However, certain electronic components comprising the electronic verification device, such as pressure detectors, are assembled in such a way that they are free from internal contamination while remaining open to the tire atmosphere, as necessary. A rubber tire patch having a pre-selected configuration is formed. The rubber patch includes a first side to interconnect with the face of the rigid label assembly. This first side has an increased surface area, which allows a better union with the encapsulated label. The first side also includes a recessed cavity that is surrounded by a ridge of material with sufficient height to capture the rigid label structure of the sack. This flange helps to improve the union between the rubber patch and the encapsulated rigid label. The patch includes a second opposite side, the second side approaches the outline of the inner lining of the tire. The patch tapers from the first side to the second side, with the second side flared outward in a relatively thin configuration, but having a radius that approximates the radius of the inner lining of the tire. The rubber patch is vulcanized at a pre-selected temperature and for a sufficient time for its vulcanization. After vulcanizing, a thin layer of dual curing bonding rubber is applied to the second side of the vulcanized rubber patch. This thin layer of dual-curing bonding rubber will allow the patch structure to be assembled to the inner lining of the tire. A fluid epoxy adhesive is applied to an interface between the encapsulated label structure and the rubber patch. The encapsulated label structure is assembled in the recessed cavity on the first side of the rubber patch, so that the fluid epoxy adhesive is evenly distributed across the interface and flows from the interface between the encapsulated label structure and the rubber patch. Of course, the increased surface area of the tag structure allows for better bonding between the rubber patch and the encapsulated tag. The structure of the encapsulated label and the rubber patch are allowed to cure to form a patch structure. The patch structure is then assembled to the inner lining of a vulcanized tire by applying an activating cement between the dual cure bonding layer and the inner lining of the tire. This curing process permanently binds the patch structure to the inner lining and is controlled by diffusion. Because it is controlled by diffusion, curing must be done for a sufficient amount of time and at a sufficient temperature, to allow a strong permanent bond to form. To ensure that solid contact is maintained at the interface between the inner liner of the tire and the dual-curing bonding layer of the patch structure, an interlocking mechanism is applied to hold the patch structure to the inner liner during the curing process. . The clamping mechanism is applied with sufficient pressure through the interface of the patch structure and the inner liner to ensure intimate contact during curing.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Modalities of the present invention will be described below with reference to the drawings. Figure 1 shows a tire patch 10 of the present invention. The tire patch is of a pre-selected configuration, which as illustrated is rectangular in shape. The patch may be of any other convenient configuration, but it is shown as rectangular and therefore has four edges 11. The tire patch 10 has a first side 12 for interconnecting with a face of an encapsulated tag structure 30 illustrated in the Figure 2. The patch has a second opposite side 14 that approximates the contour of an inner lining of a tire. The contour of the second side 14 is preferably radial so that it has approximately the same radius as the tire to which it is assembled, the radius is larger for larger tires. For very large tires, such as for off-road vehicles, the radius can be totally eliminated, so that there is no contour and the opposite side is flat, without contour.
The rubber patch is vulcanized at a pre-selected temperature and for a sufficient time to cure the patch. The patch may be rubber selected from the group consisting of ethylene, propylene or diene monomer rubber (EPDM = Ethylene Propylene Diene Monomer), butyl rubber, natural rubber, neoprene and mixtures thereof. A preferred embodiment is a mixture of slorobutiló rubber and natural rubber. Another preferred embodiment is a mixture of styrene-butadiene rubber (SBR = Styrene Butadiene Rubber) and natural rubber. Typically, patches made from these rubber compositions can be cured by heating to a temperature of about 150 ° C and maintaining this temperature for about 30 minutes. The time and temperature can be modified as necessary to achieve sufficient cure of the patch for additional assembly. The first side 12 includes a recessed cavity 16 which is surrounded by a raised edge 18 of rubberized polymeric material. The optionally recessed cavity may have a rough bottom surface to increase its surface area. The flange 18 is preferably of the same material as the rest of the patch. The material flange should be of sufficient height to capture the encapsulated rigid label 30. In a preferred embodiment, the flange is approximately 3,175 mm (1/8"). The patch tapers gradually from the edge 18 of the material of the first side of the material. patch 12, outwardly to the edges of the patch Fixed to the second side 14 of the vulcanized tire patch is a dual-curing bonding layer 20, having a first side (not shown) and a second side 22. This bonding layer with dual curing can be assembled into the patch at any time after vulcanization of the patch and prior to assembly of the patch structure to the inner liner of the tire.The dual-cure bonding layer is permanently assembled to the patch. shown) is applied to the side 14 of the patch in order to keep the dual cure bonding layer 20 on the patch.The uncured segment and the dual cure bonding layer are Patch Rubber Company products The important feature of the dual cure bonding layer is that it can be activated and chemically cured, without need to heat at a high temperature. The process is controlled by diffusion, however, and some minimum heating will accelerate the curing process. The dual-curing bond layer can be any material that can be activated and cured to the vulcanized rubber of the tire innerliner and the vulcanized patch. Preferably, however, the dual cured bonding rubber is natural rubber. The dual curing bonding rubber, after application of the activation cement, can cure at room temperature over a period of 72 (seventy two) hours. However, if faster curing is desired, this can be achieved by heating to 45 ° C for at least 24 (one hour) 2. Figure 2 shows a cross-sectional view of the rigid label structure 30, illustrating the device encapsulated electronic verification 32. The verification device can be a circuit board 34 that includes the electronic memory as well as a variety of detectors to verify the engineering conditions such as pressure, temperature and distance traveled. in detail in U.S. Patent No. 5,562,787, incorporated herein by reference. Mounted on the board is an energy source 36, such as a battery, which allows active verification of engineering conditions, which can be stored in memory electronics for later use.The power source provides a bulge 38 to the rigid label structure, although this feature is expected to be less prominent or be eliminated almost completely as advances in battery technology produce smaller yet more powerful batteriesThe rigid label structure can also allocate an antenna, or it can allow the assembly of an antenna that is procured from the structure of the label, so that the device on the board can be activated for transmission at will. The circuit board includes detectors, optional battery and antenna, hereinafter referred to as the electronic verification device, is encapsulated in a material 40, solidifies into a rigid material. With reference to Figure 3, the electronic verification device is placed inside a mold 40 having a first half 52 and a half secranda 54. At least one of the mold halves has a face with increased surface area illustrated as surface 56 in the second half 54 of the mold 40. The mold is then filled with the insulating material 40, in fluid form, and fills the mold v and circulates around the electronic verification device and is to be cured, resulting in a structure of a rigid pattern. Any encapsulation material has a Youns module of at least 2,109 ka / crn "(30,000 PSI) which is capable of being molded around the electronic verification device without damaging any of the components of the device. encapsulation has a Youna module of at least about 7.030 ks / cm "(100,000 psi). Two preferred encapsulation materials include epoxy and urethane. If it occurs, the curing of the encapsulation material around the electronic device can be accelerated by pre-expelling the mold at an elevated temperature which is above ambient, but below u &; the temperature at which damage will occur to the electronic verification device. A preferred temperature is about 80 ° C. After the epoxy has cured, the mold halves 52, 54 are separated, resulting in a rigid encapsulated label structure 30. The label structure 30 has a bottom surface 42 having an increased surface finish which is simply the printing of the surface 56 from the middle of the mold 54. The rigid label structure 30 is assembled in the recessed cavity 16 in the first side 12 of the tire patch 10, either after of vulcanizing the patch or after assembling the dual-bond curing layer 20 to the patch. In order to permanently adhere the label structure 30 to the patch 10, a fluid adhesive is applied to the interface between the label structure 30 and the recess 16. This adhesive, preferably an epoxy adhesive, can be conveniently applied to the surface 42 of a label structure or to the base of the recess 16. According to the structure of the label. ueta 30 is pressed into the recessed cavity 16, the epoxy adhesive flows evenly over the interface between the surface 42 and the base of the recess 16. The increased surface area between the base of the recessed cavity 16 and the surface 52, provides bonding area additional and a stronger union. Because the ridges around the recess are more closely dimensioned to correspond to the dimensions of the label structure 30, excess epoxy will flow between the label structure 30 and the flange 18, and some epoxy may even circulate out of this. region. Of course, the epoxy flow of this region will contribute to the strength of the structure as the epoxy sets. While the epoxy can be allowed to cure at room temperature, the curing process can be accelerated by heating the structure to an elevated temperature, for example a temperature from about 75 to 90 ° C, at least about 30 minutes, if the layer The dual cure joint has not yet been assembled to the second side 14 of the tire patch 10, it can be added at this time to form the patch structure 60. Referring now to Figure 5, the parohe structure 60 is then assembled to the liner interior 75 of the tire 70. The activation cement again is applied to the second node 22 of the dual-curing bonding layer 20. The patch structure is then stitched to the inner lining of the vulcanized tire and the tire structure / patch structure It is necessary to cure for a time and temperature su icients to form a strong union between the patch structure and the tire. The times and temperatures used for this curing can be basically the same times and temperatures as previously discussed. To ensure strong bonding, the patch structure can optionally be clamped to the inner lining of tire 75 until the cure cycle is complete. Figure 6 shows an alternate configuration of a tire patch 110 of the present invention. The tire patch 110 is of a pre-selected configuration, which as illustrated is round in shape. The tire patch 110 has a first side 112 for interconnecting with a face of a collapsed label structure 130, which is illustrated in cross section of Figure 7. The first side 102 includes a recessed cavity 116 which in this alternating configuration is formed by a rigid cylindrical insert 117 molded into the rubber patch. Preferably, the cylindrical insert 117 is a rigid plastic material such as nylon, epoxy or a rigid composite such as a glass filled or epoxy filled polyimide, but it can also be a metal, as long as the metal does not interfere with the electronic functions and operation of the label structure 130. The rigid cylindrical insert 117 is surrounded by a rim 118 of rubberized material. The flange is preferably of the same material as the rest of the patch and should be of sufficient height to permanently hold the cylindrical insert 117 in place after curing. In a preferred embodiment illustrated in Figures 6 and 7, the rim 118 is of the same height as the cylindrical insert 117. The patch gradually tapers from the rim 118 of the material of the first side of the patch outward toward the edges of the patch. The recessed cavity 116 may have a rough bottom surface to increase its surface area, as previously described, or alternately may be smooth and made from the same material as the cylindrical insert. The patch has a second opposing side 114 that can approximate the contour of an inner lining of a tire. The contour of the second side 114 is preferably radiated to have approximately the same radius as the tire to which it is assembled, the radius is larger for larger tires. For very large tires, such as off-road vehicles, the radius can be completely eliminated, so that there is no contour and the opposite side 114 is flat, without contour. The patch 110 including the cylindrical rigid insert 117 is cured or set before insertion of the rigid label structure 130 to form a round patch structure. The rigid label structure 130 which includes encapsulated electronic verification devices and has the same components as previously described, is essentially identical to the rigid label structure 30 except for its profile which is round or circular instead of rectangular. The round rigid label structure 130 is permanently chosen from the round patch structure, by inserting the rigid label structure 130 into the cylindrical insert 117, as illustrated in Figure 8, after applying an epoxy adhesive such as a Fusor system. manufactured by Lord Corp. of Erie PA , at the interface between the rigid label structure 130 and the cylindrical insert 117, Of course, the epoxy adhesive can also be conveniently applied to the interface and between the bottom of the cavity 116, whether a rough surface is processed or processed of a material equal or similar to the cylindrical insert 117. As the rigid label structure 130 is placed in the cylindrical insert 117, excess epoxy flows out of the interface, which must be removed before curing. The cylindrical insert 117 should only be of sufficient height, such that after curing the epoxy, there is sufficient bond strength between the insert 117 and the tag structure 130 to ensure there is no separation. Although the rigid tag structure 130 may be of the same height as the cylindrical insert 117 as illustrated in the preferred embodiment, it may also be lower or higher than the cylindrical insert 117, when assembled. If the label structure 130 is larger than the cylindrical insert 117, then the insert 117 has a smaller profile than the rigid label structure 130, such that the outer periphery of the rigid label structure 130 extends over the outer periphery of the cylindrical insert 117, thereby reducing the total amount of material required for the pneumatic patch 110. The patch structure 160 formed by assembling the rigid label structure 130 in the pneumatic patch 110 is attached to a tire using the same materials and methods described above for the patch structure 60. The patch structures manufactured and assembled to an inner lining of the tire in the manner described above, have passed tests equivalent to 160,000 kilometers (100,000 miles) and have been completely bound to the tire.
