Description

  The present invention relates to a method of manufacturing a temperature detector that can conduct electricity by detecting even a part of a target temperature such as an abnormally high temperature and detect a predetermined temperature.

  Conventionally, in order to detect abnormal temperatures in thermal equipment, lithium secondary batteries, and the like, element-shaped thermal fuses and thermistors have been used as safety devices. In addition, when there is a wide range of places where there is a possibility of abnormal temperatures, a plurality of temperature fuses and thermistors have been connected to improve safety. However, in such a configuration, there is a problem that a portion that detects an abnormal temperature is a point, and it is not certain whether it acts reliably on an abnormal temperature that occurs locally. Further, since the amount of use of the thermal fuse and thermistor increases, there is a problem that not only the part cost increases, but also the connecting process takes a lot of man-hours, so that the operation cost becomes very high.

  Conventionally, various planar thermal fuses are known as solutions for such problems. For example, as in Patent Document 1, a thermoplastic resin film is interposed between a film sheet-like flat electrode and a film-like heat detection electrode in which unevenness or a plurality of holes are formed, and these are polyethylene terephthalate films. What was covered with is mentioned. In Patent Document 1, when an abnormally high temperature occurs, the thermoplastic resin film melts and flows into the concave and convex recesses or the plurality of holes formed on the surface of the heat detection electrode, and the heat detection electrode and the planar electrode come into contact with each other. This is related to a technique of detecting an abnormal temperature by conducting the electric field.

  Further, as in Patent Document 2, there is a configuration in which two plate-like electrode plates face each other, and an electrically insulating substance that melts at a temperature equal to or higher than a predetermined value is sandwiched between the two plate electrode plates. This Patent Document 2 relates to a technique in which an electrically insulating substance is melted by overheating, both electrode plates are brought into contact, and are electrically connected to detect an abnormality.

  Although not directly related to the present application, in the field of the heating wire, for example, as in Patent Document 3, a pair of spiral electrode wires is formed on the outer surface of the PTC heating element layer, and this electrode wire and PTC heating It is known that a heat-meltable polymer layer is formed so as to be in contact with the body layer, and a conductor wire is further formed on the outer surface of the heat-meltable polymer layer. This Patent Document 3 relates to a technique in which a meltable polymer layer is melted against abnormal overheating, and a spiral electrode wire and an outermost conductor wire come into contact with each other to prevent overheating.

  In addition, Patent Document 4 and Patent Document 5 have been filed by the present patent applicant as technologies related to the present application. The temperature detectors according to Patent Document 4 and Patent Document 5 have a long first electrode having a spring property and a long first electrode having a spring property that is adjacent to and arranged with respect to the first electrode. Two electrodes, and a spacer that is made of an insulating material and is arranged to insulate the first electrode and the second electrode that are biased in one direction, the first electrode and the first electrode Both of the two electrodes have a stranded wire structure, and when exposed to a predetermined temperature, the insulation between the first electrode and the second electrode by the spacer is released, whereby the first electrode and the above-mentioned A predetermined temperature is detected by contact / conduction with the second electrode. As a specific form, an example in which a first electrode and a second electrode are twisted together is disclosed.

JP-A-6-229839 JP-A-9-145164 JP 59-207586 A International Publication WO2008 / 044458 Japanese Patent Application No. 2008-74161

  Here, in the case of the planar thermal fuse disclosed in Patent Document 1, unless a sufficient depth is provided in the concave portion or the hole portion of the heat detection electrode, the thermoplastic resin film is not formed between the heat detection electrode and the planar electrode. A part remains, and the heat detection electrode and the planar electrode cannot be reliably brought into contact with each other. However, if the recess or hole of the heat detection electrode has a sufficient depth, the thickness of the heat detection electrode increases and flexibility as a planar temperature fuse cannot be obtained.

In addition, the planar thermal fuse disclosed in Patent Document 2 does not have a space for the molten electrically insulating material to move, and therefore remains between the two electrode plates in a molten state. It may be impossible to plan. Further, this Patent Document 2 discloses the use of a material in which solder particles are mixed in a flux as an electrically insulating material. As a result, when the temperature is abnormal, the flux melts and disappears, and the solder particles overlap or fuse to provide a bridge between the two electrode plates. However, in this case, it is considered that the melted solder becomes a small sphere at the time of detection due to the effect of the flux and is separated, and the two electrode plates cannot conduct. In addition, when used in a high temperature environment for a long time, the flux may be dissipated due to thermal deterioration. In this case, even if the temperature does not reach the abnormal temperature, the two electrode plates become conductive and malfunction. become.

  In the heating wire described in Patent Document 3, the spiral electrode wire is simply wound around the PTC heating element layer, and the outermost conductor wire is simply wound around the heat-meltable polymer layer. is there. Therefore, even if abnormal overheating occurs locally and the heat-meltable polymer layer melts, the force that changes the distance between the spiral electrode wire and the conductor wire does not work. It is possible that contact will not occur.

  Patent Document 4 and Patent Document 5 are based on such points, and are electrically conductive by being partially exposed to a target temperature such as an abnormally high temperature. Since it is excellent in flexibility, it can be attached to detection objects of various shapes, and furthermore, a temperature detection body having excellent operation reliability can be provided.

  However, in the temperature detector according to Patent Document 4 and Patent Document 5, when the first electrode and the second electrode are twisted together, the twist stress remains, and the entire temperature detector is twisted. There was a concern that this would be a problem. If it becomes such a twisted state, when attaching a temperature detection body to a detection target, alignment will become very difficult. In this case, since it is thin and excellent in flexibility, the effect that it can be mounted on a detection target having various shapes is not sufficiently exhibited. Therefore, in order to eliminate this twist, further improvement of the manufacturing method has been desired.

  The present invention has been made on the basis of such points, and the purpose thereof is to be conducted by being partially exposed to a target temperature such as an abnormally high temperature, to detect the temperature, An object of the present invention is to provide a method of manufacturing a temperature detector that has excellent operational reliability, is thin and flexible, and can be easily attached to detection objects of various shapes.

In order to achieve the above object, a method of manufacturing a temperature detector according to claim 1 of the present invention includes a long first electrode and a long second electrode adjacent to and disposed with respect to the first electrode. And a spacer made of an insulating material and arranged to insulate the first electrode and the second electrode, and a pair of sheet-like base materials, the first electrode and the second electrode The electrode is a twisted electrode in which the electrodes are twisted together, and by being exposed to a predetermined temperature, the insulation of the first electrode and the second electrode by the spacer is released, thereby the first electrode A method of manufacturing a temperature detector that detects a predetermined temperature by contact / conduction between an electrode and the second electrode, the spacer covering the first electrode and / or the second electrode, Twisting the first electrode and the second electrode into a twisted electrode; A step of back twist twisting electrodes, the 該撚 Ri electrode is characterized in that consists of the steps to be sandwiched between the pair of substrates.
According to a second aspect of the present invention, there is provided a method of manufacturing a temperature detector, comprising: a long first electrode; a long second electrode adjacent to and arranged with respect to the first electrode; and an insulating material. The spacer is disposed so as to insulate the first electrode from the second electrode and a pair of sheet-like base materials, and the first electrode and the second electrode are twisted together. By being exposed to a predetermined temperature, the insulation between the first electrode and the second electrode by the spacer is released, whereby the first electrode and the second electrode are released. A method of manufacturing a temperature detector that detects a predetermined temperature by contact / conduction with an electrode, wherein the first electrode and / or the second electrode is covered with a spacer, and the first electrode and the second electrode A step of twisting two electrodes together to form a twisted electrode, and the twisted electrode is opposite to the twisting direction. A step of the untwisted and feed line while rotating in direction, the 該撚 Ri electrode is characterized in that consists of the steps to be sandwiched between the pair of substrates.
According to a third aspect of the present invention, there is provided a method for producing a temperature detector, wherein the first electrode and / or the second electrode has a spring property.
According to a fourth aspect of the present invention, there is provided the method for manufacturing a temperature detector, wherein the first electrode and the second electrode have spring properties, and the first electrode and the second electrode are both twisted. It is characterized by a line structure.
According to a fifth aspect of the present invention, there is provided a method for manufacturing a temperature detector, wherein the spacer is melted at a predetermined temperature.

  According to the manufacturing method of the temperature detection body by this invention, since the twist stress can be removed by twisting back a twist electrode, the whole temperature detection body does not become a twisted state. Therefore, positioning at the time of attachment to a detection target is very easy, and it can be easily mounted on detection targets of various shapes.

  The first embodiment of the present invention will be described below with reference to FIGS. The planar temperature detector according to the present embodiment is configured to detect a temperature in the vicinity of 85 ° C.

  As shown in FIG. 1, a spacer made of a mixture of hot melt adhesive (melting point 85 ° C.) and solid wax (melting point 85 ° C.) is provided on the outer periphery of the first electrode 1 formed by twisting seven SUS304 stainless steel wires. 3 is extrusion coated. In addition, the outer periphery of the second electrode 2 formed by twisting seven SUS304 stainless steel wires is covered with a spacer 3 made of a mixture of a hot melt adhesive (melting point 85 ° C.) and solid wax (melting point 85 ° C.). ing. The first electrode 1 and the second electrode 2 are twisted at a pitch of 10 mm to form a twisted electrode 4, which is once wound around a bobbin. In this way, the first electrode 1 and the second electrode 2 are made of SUS304 stainless steel wire, which is a material having spring properties, and twisted to form the first electrode 1 and the second electrode 2. A force to make a straight line acts and the state is urged.

  The bobbin around which the twisted electrode 4 is wound is attached to a rotary feeder, and is twisted back by being fed while rotating in the direction opposite to the twisting direction of the twisted electrode 4. It is pinched. The feed line conditions are a feed speed of 5 m / min and a rotation speed of 50 rpm. One of the pair of base materials 5 is a non-woven fabric 5a made of PET (polyethylene terephthalate), and the other is a film 5b made of PET coated with an adhesive on one side. The nonwoven fabric 5a and the film 5b will adhere. In this way, the temperature detector 10 according to the present embodiment is configured. And the temperature detection body 10 which makes the said structure is installed in the predetermined | prescribed position of the outer periphery in arbitrary thermal equipment 11, as shown, for example in FIG. Thereby, the abnormal temperature in the thermal equipment 11 is detected.

  The circuit configuration of the temperature detector 10 is as shown in FIG. In the figure, reference numeral 6 is a power source, and reference numeral 7 is an ammeter. In the circuit diagram shown in FIG. 2, when the spacer 3 is not melted, the circuit is cut off. On the other hand, when the spacer 3 is melted at a predetermined temperature, the first electrode 1 and the second electrode 2 come into contact with each other. As a result, a current flows through the circuit, and it is detected that a predetermined temperature has been reached.

  The temperature detector 10 thus obtained is placed in a heating tank (not shown) and the temperature is raised at 1 ° C./min. In the circuit diagram shown in FIG. 2, the temperature when the spacer 3 was melted and the first electrode 1 and the second electrode 2 contacted and energized was measured as the detected temperature. The number of samples was 5. As a result, any sample was detected at 85 to 90 ° C., and it was confirmed that it was possible to reliably detect the target temperature.

  According to the above-described embodiment, before reaching the target temperature, the first electrode 1 and the second electrode 2 are energized by a force that tends to be linear. The first electrode 1 and the second electrode 2 are placed at a distance from each other by the spacer 3 covered with the first electrode 1 and the second electrode 2, that is, the first electrode and The second electrode 2 is fixed and held by the spacer with the biased state. When even a part of the temperature detecting body reaches the target temperature, the fixed holding in the biased state is released by melting the spacer 3, and the first electrode 1 is positively moved to the second electrode 1. Since the second electrode 2 goes to contact the electrode 2 and the second electrode 2 goes to contact the first electrode 1, the first electrode 1 and the second electrode 2 are surely connected to each other to detect the temperature. Can do. Moreover, since the first electrode 1, the second electrode 2, the spacer 3, the nonwoven fabric 5a, and the film 5b are not thick and have excellent flexibility, the temperature detector 10 as a whole is also used. It can be made thin and excellent in flexibility.

  In addition, since the outer periphery of the first electrode 1 and the second electrode 2 is coated with the spacer 3, the first electrode 1 and the spacer 3 and the second electrode 2 and the spacer 3 are formed in one linear shape. Since it can be handled as a body, it can be easily handled and placed on a substrate, and productivity can be improved. Furthermore, since the spacer 3 completely covers the first electrode 1 and the second electrode 2, conduction in a state where the target temperature has not been reached, that is, malfunction can be reliably prevented.

  The temperature detector 10 according to the present invention is not limited to the above embodiment. The first electrode 1 may be a conductor. A conductor having spring properties is particularly preferable, and the material is not limited, for example, a hard steel wire, a piano wire, an oil tempered wire, a stainless steel wire, or the like. In addition, for example, an insulating material having a spring property and a conductive wire wound horizontally may be considered. The shape is not particularly limited as long as it does not prevent positive contact with the second electrode when the fixed holding in the biased state is released. However, in the present invention, a twisted wire is preferable. In the embodiment described above, a SUS304 stainless steel wire having the same thickness is used as a stranded wire.For example, when forming the spacer 3 by making only the wire arranged at the center slightly thick, When arrange | positioning to the base material 5, it can prevent that the line | wire arrange | positioned in the center jumps out of twist. It can be considered that the first electrode 1 is arranged on the substrate 5 in various shapes such as a meandering shape and a linear shape. At this time, the first electrode 1 may be composed of a plurality of conductors instead of a single conductor. For example, a plurality of linear conductors are formed in a net shape, One electrode 1 may be used. The second electrode 2 may be configured in the same manner as the first electrode. In particular, when the first electrode and / or the second electrode has a spring property, the force of making a straight line increases, so the function of temperature detection is improved, but the residual stress also increases, It is important to perform twisting such as feeding while rotating as in the invention.

  FIG. 4 shows details of the above embodiment. Since the first electrode 1 and the second electrode 2 have a stranded wire structure, when the spacer 3 is melted during temperature detection, the first electrode 1 and the second electrode 2 as a whole tend to be straight. Since both the force and the untwisting force of the stranded wire work, the first electrode 1 and the second electrode 2 are easy to approach each other, thereby making it more reliable and quick. Detection is possible. Moreover, when setting it as such a strand wire structure, you may comprise a stainless steel wire and an annealed copper wire by twisting suitably. By doing so, it is possible to adjust the spring property and the flexibility so that the arrangement of the first electrode 1 and the second electrode 2 and the terminal attaching process to the terminal are facilitated. In particular, when the stainless steel wire and the annealed copper wire are twisted together, if the center is made of stainless steel wire and the annealed copper wire is arranged on the outer periphery, the twist becomes difficult to be crushed and the terminal contacts with the terminal. Since resistance and the contact resistance at the time of the 1st electrode 1 and the 2nd electrode 2 electrically conducting become low, it is preferable.

  Next, as the spacer 3, the first electrode 1 can be fixed and held in an energized state before reaching the target temperature, and the fixed holding is released when the target temperature is reached. There is no particular limitation as long as it is possible. For example, the shape and arrangement of the first electrode 1 and the second electrode 2 such as those that melt at a predetermined temperature, those that evaporate, those that shrink, and those that reduce the viscosity, or the shape and arrangement of the spacer 3 itself Appropriate selection may be made according to the above. Among these, those that melt at a predetermined temperature are preferable because they can be most easily used and the detection temperature can be easily set. Examples of materials that melt at a predetermined temperature include polyethylene resin, ethylene-vinyl acetate copolymer resin, polyester resin, polyamide resin, polyvinyl alcohol copolymer resin, polyvinylidene chloride resin, polyvinyl chloride resin, polyurethane resin, Production of thermoplastic resins such as polypropylene resins, thermoplastic elastomers such as olefinic elastomers, organic salts, natural waxes such as plant-based, animal-based, ore-based, petroleum-based waxes such as paraffin, microwax, and petratum wax, and wax generation Synthetic resins such as products, resin products, asphalt products, fatty acids, fatty acid salts, and the like, and mixtures thereof, and those having a melting point suitable for the target temperature may be appropriately selected. . Among the above, when an ethylene-based material is used, it is preferable to use a material polymerized by a metallocene catalyst because the polymer structure is uniform and the melting temperature is less varied.

  A preferable form of the base material 5 when the spacer 3 is melted at a predetermined temperature is such that the melted spacer 3 can move, that is, has a shape and configuration that can flow. Just do it. For example, a sheet provided with unevenness or a hole or a net made of various linear materials is conceivable, but it is particularly preferable that the melted spacer 3 can be absorbed. This is because the contact between the first electrode 1 and the second electrode 2 can be performed more rapidly by effectively absorbing the molten spacer 3. Examples of the base material 5 that can absorb such a melted spacer 3 include not only the nonwoven fabric described in the above embodiment, but also mesh cloth, sponge, woven fabric, paper, and the like. In addition, there is no limitation in particular about the material which comprises the base material 5. FIG. In the above embodiment, the film 5b made of PET is used as one base material. However, a PET film or the like may be used for both base materials, and a non-woven fabric may be used for both base materials. .

  In FIG. 1, the twisted electrode 4 obtained by twisting the first electrode 1 and the second electrode 2 is arranged in a straight line, but in such a shape, There is no limit. What is necessary is just to arrange | position in the shape designed suitably according to the shape and various use conditions, etc. of the heat equipment 11, etc. For example, as shown in FIG. 8, what twisted the 1st electrode 1 and the 2nd electrode 2 is shown. It may be arranged in a meandering shape.

  However, if it is arranged in a meandering shape as shown in FIG. 8, even if the surface of the thermal device 11 is a curved surface or an intricate shape, it can be made to follow the shape easily. That is, when arranged in a meandering shape, it is arranged obliquely with respect to a curved surface or an intricate shape, so that the bending radius of the electrode itself is increased, and as a result, adhesion is improved. Further, even when an external force such as pulling or bending is applied to the temperature detector 10 at the time of placement, it is difficult to apply an excessive force to the first electrode 1 or the second electrode 2. It is preferable because disconnection of the electrode 2 can be prevented. Moreover, about the state which twisted the 1st electrode 1 and the 2nd electrode 2, the form etc. which the 1st electrode 1 was wound horizontally on the outer periphery of the 2nd electrode 2 etc. are contained, for example. This is because the first electrode 1 and the second electrode 2 are easy to contact after the insulation by the spacer 3 is released.

Further, the feed speed and the rotational speed during the feeding line, so that the twist of the twisted electrode 4 sets the condition in relation to the pitch. Preferably, the conditions are such that the twisted electrode 4 is slightly twisted (a condition in which the twisted electrode 4 rotates 0.3 to 2 every time 10 pitches are fed). If the rotation is slower than this, the stress due to twisting remains, and the twist cannot be removed. Also, if the rotation is faster than this, this will cause twisting in the opposite direction.

  Further, in the above embodiment, the twisted electrode 4 is rotated while being rotated in the direction opposite to the twisted direction, is twisted back, and is sandwiched between the pair of base materials 5 as it is. It is not limited to. For example, before being sandwiched between a pair of base materials 5, the twisted electrode 4 is re-wound around another bobbin while rotating in the direction opposite to the twist direction, and then twisted again between the base materials 5. Alternatively, the twisted electrode 4 may be supplied. However, in this case, the number of man-hours increases, and in particular, when using the first electrode or the second electrode having a spring property, twisting may be disturbed during rewinding. It is preferable to carry out in a continuous process. Moreover, as a method of untwisting, for example, each of the first electrode 1 and the second electrode 2 is previously twisted in a direction opposite to the twisting direction of the twisting electrode 4, and then the first electrode 1 It is also conceivable to twist the electrode 2 and the second electrode 2 into the twisted electrode 4. Such a method is performed, for example, by using a twisting machine having a twisting back function. However, such a twisting machine has a problem that the equipment becomes large.

  Next, a second embodiment of the present invention will be described with reference to FIG. In the case of the second embodiment, in this case, the twisting directions of the strands of the first electrode 1 and the second electrode 2 are reversed. The other configurations are the same as those in the first embodiment, and the same parts are denoted by the same reference numerals and the description thereof is omitted.

  Also in this case, the same effect as in the case of the first embodiment can be obtained. Moreover, since the twist direction of the strands of the first electrode 1 and the second electrode 2 is opposite, when the spacers 3 and 3 are melted at the time of temperature detection, the first electrode 1 and the second electrode 2 Since both the action of the entire electrode 2 to become a straight line and the untwisting force of the stranded wire act, the return directions of the stranded wires are close to each other. One electrode 1 and the second electrode 2 are easy to approach each other, thereby enabling more reliable and quick detection.

  Next, a third embodiment of the present invention will be described with reference to FIG. In the case where the first electrode 1 and the second electrode 2 covered with the spacer 3 are twisted together, as shown in FIG. 6, the first electrode 1 and the second electrode 2 covered with the spacer 3 are used. A braid 21 made of various fiber materials, fine metal wires, or the like may be applied to the outer periphery where the two are twisted together. Thereby, since the space can be provided around the first electrode 1 and the second electrode 2 covered with the spacer 3, the melted spacer 3 is easily moved to the base material 5. Further, if the braid 21 is made of a conductive material such as a fine metal wire, the braid 21 can also function in the same manner as the second electrode 2.

  Next, a fourth embodiment of the present invention will be described with reference to FIG. In the case where the first electrode 1 and the second electrode 2 covered with the spacer 3 are twisted, as shown in FIG. 7, the first electrode 1 and the second electrode 2 covered with the spacer 3 are used. You may give the horizontal winding 22 which consists of various fiber materials, a metal fine wire, etc. to the outer periphery which twisted together. Thereby, since the space can be provided around the first electrode 1 and the second electrode 2 covered with the spacer 3, the melted spacer 3 is easily moved to the base material 5. Further, if the horizontal winding 22 is made of a conductive material such as a fine metal wire, the horizontal winding 22 can function in the same manner as the second electrode 2.

  The present invention is not limited to the first to fourth embodiments. For example, the first electrode 1 or the second electrode 2 may have a heater function. Thereby, it can have a heating function and a temperature detection function. As a specific aspect, for example, it can be considered that either the first electrode 1 or the second electrode 2 is a heater wire. At this time, if the other electrode is the above-described sensor wire, heating can be performed with the heater wire while controlling the temperature with the sensor wire in the normal state. Therefore, energization can be cut off by detecting a potential difference that varies greatly. Examples of the heater wire include a resistance wire such as a nichrome wire and a Kanthal wire, and those wound around an outer periphery of a tensile body such as a Kevlar core. As the sensor wire, for example, a wire in which a temperature detection wire such as a Ni wire is wound around the outer periphery of a tensile body such as a Kevlar core can be considered. When the first electrode is a heater wire or a sensor wire, it is preferable to use a material having a spring property as a strength member. However, when a conductive material is used for the strength member, it is necessary to provide an insulating coating on the outer periphery thereof. As another aspect, a combination of the above-described sensor wire and heater wire may be considered. For example, the outer periphery of the sensor wire is covered with an insulator, and a resistance wire is wound around the outer periphery. Examples include those in which an outer periphery is covered with an insulator and a temperature detection wire is wound around the outer periphery, and a resistance wire and a temperature detection wire are wound around the outer periphery of the tensile body so as not to contact each other.

  In addition to the first electrode 1 and the second electrode 2, a heater wire may be provided. For example, a heater wire is disposed between the first electrode 1 and the second electrode 2 if the first electrode 1 and the second electrode 2 are insulated from the target temperature or lower. You may do it.

  As described above in detail, the manufacturing method according to the present invention is electrically conductive by being partially exposed to a target temperature such as an abnormally high temperature, can detect the temperature, and has excellent operation reliability. Furthermore, it is possible to obtain a temperature detection body that is thin and excellent in flexibility and can be easily attached to detection objects of various shapes. In addition, examples of the use of the temperature detector obtained by this manufacturing method include, for example, a secondary battery, a water heater, a refrigerator, an air conditioner indoor / outdoor unit, a clothes dryer, a jar rice cooker, a hot plate, a coffee maker, a water heater, It can be used for ceramic heaters, petroleum heaters, vending machines, thermal futons, floor heating panel heaters, copying machines, facsimiles, tableware dryers, fryer.
