Description

  TECHNICAL FIELD The present invention relates to a jig for manufacturing a planar heating element, that is, a plate heater used in various fields such as a vending machine for drinks or the like, for example, a vending machine such as coffee or a defroster of a refrigerator.

  The basic structure of the plate heater is such that the heater wires are routed with a predetermined pattern within the required range of an aluminum foil having a predetermined area. Then, the heater wire is energized through a lead wire to raise the temperature, and the temperature is made uniform by an aluminum foil so as to have functions such as heat retention or defrosting.

  It goes without saying that the pattern or form of the heater wire on the aluminum foil varies depending on the counterpart device used, and it is designed and set as necessary. If not, the performance as a plate heater is greatly affected. Of course, the size (plan view) as the plate heater is also various.

  As described above, the handling of the heater wire affects the performance as a plate heater. Therefore, the handling of the heater wire requires accuracy such as the arrangement state of the heater wire.

  However, it was not so old that the heater wire was completely handled manually, for example, an aluminum foil coated with adhesive or adhesive on the surface was placed on the workbench and placed on the aluminum foil. In this method, the heater wire is manually routed based on a predetermined pattern and then pressed by a press or other means to integrate the aluminum foil and the heater wire. In such a method, it is difficult to keep the heater wire in a fixed state, it is difficult to stably ensure the performance as a plate heater, and inevitably, careful work and skill are required. Therefore, the work efficiency was poor, and the high defect rate at the manufacturing stage was also a problem.

As a method for solving such problems, the methods shown in FIGS. 19 and 20 are adopted. That is, adoption of the jig J ₀ for maneuverability heater wire. A groove J ₀₁ is formed in the jig J ₀ in a predetermined pattern, and the groove A ₀₁ is drawn in the same pattern as the groove J ₀₁ in the aluminum foil A ₀ to be used. In this method, first placing the jig J ₀ on a workbench, and then sets the aluminum foil A ₀ to the jig J _0. At this time, since the groove A ₀₁ is drawn in the same pattern as the groove J ₀₁ on the aluminum foil A ₀ , it can be easily set. Thereafter, the heater wire H ₀ is routed along the groove A ₀₁ . Thus, compared with the groove A ₀₁ formed in adopting the aluminum foil A ₀ of the jig J _0, handling work of the heater wire H ₀ be easier, that state even small variations, the performance of the plate heater Can be secured stably.

  Certainly, using the jig in which the heater wire arrangement pattern is formed in a groove shape, and the aluminum foil has the same pattern as the jig, the groove is drawn in the conventional technology, the heater wire handling work is not As a result, the variation in the handling state is reduced, and as a result, the performance as a plate heater can be secured relatively stably.

  However, the operation of arranging and arranging the heater wire along the groove is not always easy, and when the heater wire is arranged, the heater wire is detached from the groove, and the operation operation is often re-executed. If the arrangement pattern is complicated, the problem of falling off the heater wire from the groove is prominent, leading to a reduction in work efficiency, which increases the work man-hours, and there is a concern about adverse effects on product costs. It was.

  In view of the problems of the prior art, the present invention arranges a plurality of pin members so as to be able to protrude and retract on the jig surface portion, and gives the plurality of pin members a predetermined function, thereby Arrangement or handling work is made extremely easy, work efficiency is improved, man-hours are reduced, and the state of arrangement of aluminum foil and heater wire is automatically fixed, thereby achieving performance as a plate heater. It is an object of the present invention to provide a jig for manufacturing a plate heater that is stable in quality, reliable in quality, and advantageous in cost.

In order to achieve the above object, according to the first aspect of the present invention, a plurality of pins each having a function are provided in a predetermined position on the surface of the jig main body so as to be able to protrude and retract, and the heater wires are interposed by interposing the pins. A jig for carrying out the setting and setting of the aluminum foil, wherein the plurality of pins correspond to the arrangement of the wiring pins and the aluminum foil arranged so as to correspond to the arrangement pattern of the heater wires. In addition, the guide pins are arranged with a slight margin and set higher than other pin members, and a plurality of guide pins are arranged together to reduce the diameter of the projecting portion and make it as dense as possible. set disposed, is obtained by configuration from an adjustment pin for adjusting the terminal position of the heater wire. With this configuration, the heater wire can be simply routed along the wiring pins, and the set of aluminum foil is set to the inside of the guide pins set higher than the other pin members. Therefore, it is possible to easily set by the simple work, so that the work efficiency can be improved and man-hours can be reduced. Furthermore, the adjustment pin has a small diameter of the projecting portion, and a plurality of adjustment pins are arranged in a collective state, and are set and arranged as densely as possible, so by changing the pin used when handling the heater wire, It becomes possible to change the terminal position of the heater wire, thereby improving the adjustment accuracy of the terminal position of the heater wire. Therefore, it is possible to provide a jig for manufacturing a plate heater that stabilizes the performance as a plate heater, has high reliability in terms of quality, and is advantageous in terms of cost.

According to the second aspect of the present invention, a plurality of pins each having a function are provided in a predetermined position on the surface of the jig main body so as to be able to protrude and retract, the heater wires are routed through the pins, and the aluminum foil A jig for setting, wherein the plurality of pins correspond to the outer shape of the wiring pins and the aluminum foil arranged so as to correspond to the arrangement pattern of the heater wires, and have some allowance. high set guide pin than provided by and other pin member in the state, and a plurality arranged in a coherent state, to reduce the diameter of the protrusions, densely set arranged to the extent possible, the heater wire And an adjustment pin for adjusting the terminal position of the wire, and further between the wiring pin and the guide pin, in the vicinity of the track around which the heater wire is routed and in the longitudinal direction of the track, slightly with the wiring pin. Arranged at intervals of It is obtained by a structure comprising les prevention pin. With this configuration, the heater wire can be simply routed along the wiring pins, and the set of aluminum foil is set to the inside of the guide pins set higher than the other pin members. Therefore, it is possible to easily set by the simple work, so that the work efficiency can be improved and man-hours can be reduced. In addition, the adjustment pin has a small diameter of the projecting portion, and a plurality of adjustment pins are arranged in a united state. The adjustment pins are arranged as densely as possible, so it is possible to change the pin used when handling the heater wire. Thus, it is possible to change the end position of the heater wire, thereby improving the adjustment accuracy of the end position of the heater wire, and arranging the anti-blur pin and the wiring pin with a slight gap. Since the heater wire is substantially pinched, the anti-blurring pin prevents the heater wire from bulging when the heater wire is routed, and as a result, prevents the heater wire from bulging or shaking. It becomes possible. Therefore, it is possible to provide a jig for manufacturing a plate heater that further stabilizes the performance as a plate heater, has high reliability in terms of quality, and is advantageous in terms of cost.

  Since the present invention is configured as described above, the following effects can be obtained.

The jig for manufacturing plate heaters according to the present invention arranges a plurality of pins each having a function at a predetermined position on the surface of the jig main body, and arranges the pins so as to intervene the heater wires. A jig for setting aluminum foil, wherein the plurality of pins corresponds to the outer shape of the aluminum foil and the wiring pins arranged so as to correspond to the arrangement pattern of the heater wires, and has a slight margin. A guide pin set in a state of being held and set higher than other pin members, and a plurality of guide pins arranged together, a diameter of the protruding portion is reduced, and a heater is set and arranged as densely as possible. Because it is composed of an adjustment pin that adjusts the end position of the wire, it is possible to simply route the heater wire along the wiring pin, and the aluminum foil set is set higher than other pin members Guy Since it is possible to easily set a simple task of aligning the inner side of the pin, to improve the work efficiency, it is possible to achieve the number of steps reduced. Further, the adjustment accuracy of the end position of the heater wire can be improved by the adjustment pins that are arranged in a dense range as much as possible by arranging a plurality of protrusions with a small diameter. Therefore, it is possible to provide a jig for manufacturing a plate heater that stabilizes the performance as a plate heater, has high reliability in terms of quality, and is advantageous in terms of cost.

The diameter of the projecting portion is reduced, and the guide pins are set as densely as possible. And an adjustment pin for adjusting the terminal position of the heater wire, and further between the cloth wire pin and the guide pin, in the vicinity of the locus where the heater wire is routed and in the longitudinal direction of the locus. Slightly between wire pins Since it is configured to include an anti-blur pin arranged with the heater wire, it is possible to simply route the heater wire along the wiring pin, and the aluminum foil set is set higher than other pin members Since it can be easily set with the simple work of aligning with the inside of the guide pin, the work efficiency can be improved and man-hours can be reduced. Further, the diameter of the projecting portion is small, it is more disposed, by adjusting pin that is densely set arranged to the extent possible in coherent state, only it is possible to improve the adjustment accuracy of the terminal position of the heater wire In addition, since the anti-blur pin and the wiring pin are disposed with a slight gap therebetween and the heater wire is substantially sandwiched, the anti-blur pin is not connected to the heater wire when handling the heater wire. As a result, it is possible to prevent the heater wire from bulging or blurring. Therefore, it is possible to provide a jig for manufacturing a plate heater that further stabilizes the performance as a plate heater, has high reliability in terms of quality, and is advantageous in terms of cost.

FIG. 3 is a simplified view showing another embodiment of a pin used in a jig for manufacturing a plate heater according to the present invention, and FIG. 4 shows still another embodiment of a pin used in a jig for manufacturing a plate heater according to the present invention. It is a simplified diagram. 5 is a cross-sectional view taken along the line AA in FIG. 1, FIG. 6 is a cross-sectional view taken along the line BB in FIG. 1, FIG. 7 is a cross-sectional view taken along the line CC in FIG. 9 is a cross-sectional view taken along line EE in FIG. 1, and FIG. 10 is a cross-sectional view taken along line FF in FIG. FIG. 11 is a cross-sectional view of a portion corresponding to FIG. 8, and is an explanatory view when a loss prevention pin is used instead of the wiring pin, and FIG. 12 is a shaft member of the loss prevention pin in FIG. FIG.

  The basic structure of the plate heater manufacturing jig according to the present invention will be described with reference to FIG. The jig J is a planarly-viewed square (rectangular in this embodiment) jig body 1 and a plurality of pin members, ie, guide pins 2, which are incorporated into the surface of the jig body 1 so as to be able to protrude and retract, The anti-blur pin 3, the wiring pins 4 and 5, and the adjustment pin 6 and a pair of left and right stopper plates 7 fixed to the surface of the jig body 1 are further disposed on the step portions formed at appropriate positions on the surface of the jig body 1. And two pairs of lead wire clips 10 and 10 fixedly attached to a step portion formed relatively wide below the surface of the jig body 1.

  The basic structure of the jig for manufacturing a plate heater according to the present invention is as described above. Among them, what is raised as an indispensable component is the jig main body 1 and the surface of the jig main body 1 appearing and protruding. A plurality of freely arranged pins, that is, guide pins 2, wiring pins 4, 5 and adjustment pins 6, and an elastic body 9 in which a connecting portion which is a connecting portion of the heater wire H and the lead wire R is located, The lead wire clip 10 is provided for applying appropriate tension to the heater wire after handling the heater wire. In the plate heater manufacturing jig according to the present invention, since a plurality of pins are used, for example, the tip of the shaft member in the pin can be easily identified based on the function of each pin. Since it is effective to attach paints of different colors to the parts, we will add them to make sure.

  In a plurality of pin members, the guide pins 2 incorporated on the outermost side have a function of restricting the setting position of the aluminum foil. In this embodiment, one guide pin is provided on the top and the bottom and two on the left and the right. I picked up what I did. The wiring pins 4 and 5 have a function of accurately and surely routing the heater wire based on the arrangement pattern in cooperation with the adjusting pin 6 described later. One is disposed slightly below the center. The difference between the wiring pin 4 and the wiring pin 5 is the pin diameter. In this embodiment, the diameter of the wiring pin 5 is larger than that of the wiring pin 4, but the diameter is not necessarily limited. There is no need to change, and it may be used corresponding to the arrangement pattern of the heater wires. The anti-blur pin 3 is disposed between the guide pin 2 and the wiring pins 4 and 5 and in the vicinity of the locus around which the heater wire H is routed. The anti-shake pins 3 have a function of preventing the heater wires from loosening or shaking between the wiring pins when the heater wires are routed. The adjustment pins 6 are arranged in the innermost state and in a plurality of states with respect to each of the pins described above, and have a smaller diameter than the other pins. This is because the adjustment pin 6 has a function of adjusting the terminal position of the heater wire after being routed.

  The pair of left and right stopper plates 7 fixed by screws 8 or the like in the vicinity of the ends on both sides of the jig body 1 are long metal plates that regulate the lowering position of the slide in the press device. In the case of manufacturing a plate heater by hot pressing, the adhesive applied to the heater wire or the aluminum foil is prevented from being excessively melted to enable proper bonding and to the surface of the jig body 1. It has a function to avoid adhesion of adhesive. Although the stopper plate 7 is attached and fixed to the left and right as a pair, it is not limited, and the size of the jig J can be increased as necessary. The elastic body 9 is a mounting portion of the connection portion between the heater wire and the lead wire, and is for preventing deformation of the connection portion during press working. The lead wire clip 10 attached and fixed symmetrically by screws 11 or the like has a substantially L shape, the rising portions are in a face-to-face state, and both rising portions are set at a constant interval. When handling the heater wire, it is considered that both ends of the lead wire are fitted to secure the tension of the heater wire after the handling and prevent loosening.

  Next, the structure of various pin members will be described in detail. In the embodiment shown in FIG. 1, the guide pin 2, the anti-blur pin 3, the wiring pins 4 and 5, and the adjustment pin 6 are shown as having different shaft member diameters and the like. For example, the wiring pin 4 and the wiring pin 5. It can be understood that the diameter of the shaft portion of the wiring pin 5 is clearly larger than the diameter of the shaft portion of the wiring pin 4. This is because it is effective to accurately reflect the set heater wire arrangement pattern on the jig J. In FIG. 1, the handling state of the heater wire H is indicated by a one-dot chain line, and it goes without saying that the heater wire H conforms to the set heater wire arrangement pattern. However, it is needless to say that it is not necessary to change the diameter of the shaft member of the wiring pin depending on the arrangement pattern, and the same wiring pin can be used. Further, it is important that the use of the same pin, that is, the common use of the pins, is applied not only to the wiring pins but also to the guide pins and the anti-blur pins. The main reason is that the basic structure of these pins is the same.

Next, the basic structure of the guide pin 2, the anti-blur pin 3, and the wiring pins 4 and 5 will be described with reference to FIG. The pin P in the basic structure includes a cylindrical cap P ₁ formed by connecting a large inner diameter portion and a small inner diameter portion, and a shaft member P ₂ having a large diameter portion P ₅ and a small diameter portion P ₆ . the small diameter portion and the large diameter portion of the cap P _1, respectively large diameter portion P ₅ and the small-diameter portion P ₆ of the shaft member P ₂ are inserted, which enables smooth sliding. The shaft member P ₂ is by a spring P _3, is biased in the (left In Fig. 2) outwardly, it is screwed to the threaded portion P ₇ formed at the end of the small diameter portion P ₆ by adjusting the nut P _4, the protruding length from the urging force and the cap P ₁ is adapted to be properly set. The material of the pin P is not particularly limited, such as brass or aluminum, but it is effective to use brass in terms of workability, cost, durability, and the like.

3 and 4 show other embodiments of the pin. However, the difference from the pin P described above is only the shaft member, and the structure is completely the same, so only the shaft member is taken up. I will explain. Shaft member embodiment according to FIG. 3, in which the silicon has been secured Sheng with arcuately distal portion of the large diameter portion P _5, the shaft member of the embodiment according to FIG. 4, the tip end portion of the large-diameter portion P ₅ It is processed into a conical shape to make a pointed shape. Thereby, as an embodiment of the pin P, there are three types, a flat head type in which the tip portion of the shaft member is a flat head type, a silicon peak type in which silicon is stacked on the tip portion, and a point type in which the tip portion is pointed. I can understand that it exists. These three types of pins can be used as guide pins or other pins as required. The details of the use of these three types of pins, particularly the silicon prime type and the pointed type, will be described later.

FIG. 1, FIG. 3, FIG. 4 shows a basic structure of an embodiment of a plate heater manufacturing jig according to the present invention. For this reason, the basic structure of the pin member, which is an important component, has been described. However, for further understanding, the description will be continued with reference to FIGS.

  The jig main body 1 will be described in detail with reference to FIG. 6 which is a BB cross-sectional view of FIG. 1 as well as FIG. 5 which is an AA cross-sectional view of FIG. The jig body 1 has a thin plate 1b fixed to the front side of the wooden base 1a, a thin plate 1c fixed to the back side, and the base 1a is formed of the plate 1b and the plate 1c. It has a sandwich-like configuration. The reason why the base 1a is made of wood is that the weight can be reduced, so that the work and carrying are easy, and the processing such as drilling is easy. In this embodiment, a plywood is used as the base 1a. This is because it is more cost-effective than a solid single plate and has relatively little secular change. Moreover, although the plate-like bodies 1b and 1c use the thin plate made from a melamine resin, it does not specifically limit.

  As described above, the jig main body 1 having such a configuration has a square shape in plan view. In FIG. 1, a step portion 1d is formed in a relatively wide range of the lower portion, and is located above the step portion 1d. Thus, a groove-shaped step 1e is connected to the left of the central portion in the left-right direction. A sponge-like elastic body 9 is attached and fixed to the groove-like step portion 1e, and two pairs of lead wire clips 10 are screwed to the lower portion of the step portion 1d so as to correspond to the elastic body 9 attachment position. 11 is attached and fixed.

  Subsequently, the arrangement of the pin members on the jig body 1 will be described with reference to FIGS.

  FIG. 7 shows a state in which the guide pin 2 is arranged on the jig body 1, that is, an attached state. The jig body 1 has an appropriate position and a predetermined number of through holes 2 h at appropriate positions. The guide pin 2 is press-fitted into the formed through hole 2h. At this time, the end surface (left end portion in FIG. 7) of the cap 2a is flush with the surface of the plate-like body 1b which is the surface side of the jig main body 1, and the large diameter portion 2e is the jig main body 1. It is in a state of protruding from the surface. In this protruding state, an appropriate urging force is applied by a nut 2d screwed into a threaded portion 2g formed at the end of the spring 2c and the small diameter portion 2f. The distance between the top 2b of the large diameter portion 2e and the surface of the plate-like body 1b, that is, the protruding length is determined by the specifications of the product plate heater. Furthermore, it goes without saying that it is determined by the specifications of the plate heater, which is a product, including the arrangement position, the number used, dimensions, etc. The planar range surrounded by the guide pins 2 attached and fixed in this way corresponds to the outer shape of the aluminum foil of the plate heater, which is a product, and is set with a slight margin. . Thereby, not only the aluminum foil setting operation at the time of manufacturing the plate heater becomes very simple, but also the aluminum foil setting to the set position can be performed reliably and accurately.

FIG. 8 shows an arrangement state, that is, an attachment state of the wiring pins 4 to the jig body 1. As a precaution, the wiring pin 5 has the same basic structure and function as the wiring pin 4 as described above. The explanation will be made assuming that the wiring pin 5 is also the wiring pin 4. A predetermined number of through holes 4h are formed at appropriate positions on the jig body 1, and the wiring pins 4 are press-fitted into the through holes 4h. (In the embodiment according to FIG. 1, all the wiring pins are used in three places, of which two are the wiring pins 4 and one are the wiring pins 5.) At this time, the cap 4 a The end surface (the left end portion in FIG. 8) is flush with the surface of the plate-like body 1b, which is the surface side of the jig body 1, and the large diameter portion 4e protrudes from the surface of the jig body 1. It is in the state. In this protruding state, an appropriate urging force is applied by a nut 4d screwed into a threaded portion 4g formed at the end of the spring 4c and the small diameter portion 4f. The distance between the top 4b of the large diameter portion 4e and the surface of the plate-like body 1b, that is, the protruding length is determined by the specifications of the product plate heater. Furthermore, it goes without saying that it is determined by the specifications of the plate heater, which is a product, including the arrangement position, the number used, dimensions, etc. The wiring pin cooperates with the adjustment pin, which will be described later, and has a function to accurately and reliably and easily arrange the most important heater wire as a plate heater based on the set pattern. What we are doing is as already mentioned.

  Next, the arrangement state, that is, the attachment state of the anti-blur pin 3 to the jig body 1 will be described with reference to FIG. An appropriate position and a predetermined number of through holes 3h are formed at appropriate positions of the jig body 1, and an anti-blur pin 3 is press-fitted into the through holes 3h. At this time, the end surface of the cap 3a (the left end portion in FIG. 9) is flush with the surface of the plate-like body 1b which is the surface side of the jig body 1, and the small diameter portion 3i is the surface of the jig body 1. It is in the state which made it protrude more. In this protruding state, an appropriate urging force is applied by a nut 3d screwed into a threaded portion 3g formed at the end of the spring 3c and the small diameter portion 3f. The distance between the top 3b of the small diameter portion 3i and the surface of the plate-like body 1b, that is, the protruding length is determined by the specifications of the product plate heater. Furthermore, it goes without saying that it is determined by the specifications of the plate heater, which is a product, including the arrangement position, the number used, dimensions, etc. In the present embodiment, the shaft member is formed by the small diameter portion 3i, the large diameter portion 3e, and the small diameter portion 3f. This is because it is better to make the protrusion part smaller in diameter than the large-diameter part 3e, rather than using the protrusion part 3e as it is. Of course, it is not limited to make the diameter smaller than the large-diameter portion 3e so as to be a protruding portion.

As can be understood from FIG. 1, the anti-blur pin 3 is between the guide pin 2 and the wiring pins 4 and 5, in the vicinity of the locus around which the heater wire H is routed, and in the longitudinal direction of the locus. However, the wiring pins 4 and 5 are arranged with a slight gap . When the handling state of the heater wire H (one-dot chain line) is seen in relation to the wiring pins 4 and 5 and the anti- blur pin 3, the heater wire H is substantially composed of the wiring pins 4 and 5 and the anti-blur pin 3. It is in a state to be sandwiched between. This makes it possible to prevent the heater wire from bulging or blurring during handling.

  Next, the adjustment pin 6 will be described with reference to FIG. The adjustment pin 6 is different in basic structure from other pin members, and the biggest difference is that no cap is used. That is, the shaft member is formed by a small diameter portion 6i, a large diameter portion 6e, and a small diameter portion 6f, and a through hole 6h in which a large diameter hole and a small diameter hole are connected to each other is formed in the jig body 1. By fitting the diameter portion 6e into the large diameter hole, inserting the small diameter portion 6f into the small diameter hole, and screwing the nut 6d into the threaded portion 6g formed at the end of the small diameter portion 6f, Arrangement on the jig body 1 is performed. Of course, a spring 6c is inserted between the large-diameter hole of the jig body 1 and the small-diameter portion 6f of the shaft member, and urges the shaft member in the protruding direction (leftward in FIG. 10). And the small diameter part 6i is in the state which protruded to the jig main body 1 surface. At this time, the end of the large diameter portion 6 e is flush with the surface of the plate-like body 1 b of the jig body 1. Here, the reason why the cap is not used in the adjustment pin 6 will be described. Since the adjustment pin 6 has an adjustment function for making the both ends of the heater wire routed the same, that is, the position of the connection portion that is the connection portion of the heater wire and the lead wire, it is necessary to improve the adjustment accuracy. The diameter of the small-diameter portion 6i, which is the protruding portion of the shaft member, is made small, and the arrangement state of the plurality of adjustment pins 6 (10 in the embodiment in FIG. 1) is made as dense as possible. This is because it is important to improve the adjustment accuracy. From such an idea, the slide of the shaft member with respect to the jig body 1 is performed directly through the through hole formed in the jig body 1 without using a cap. It should be noted that the distance between the adjustment pins is at least larger than the diameter of the heater wire, and must be set to the minimum necessary within a range that does not adversely affect the handling operation.

  Next, the loss prevention pin 12 will be described with reference to FIGS. 11 and 12. The structure of the anti-spin pin 12 is basically the same as the pin P described with reference to FIG. 2, and therefore is basically the same as the guide pin 2, the anti-blur pin 3 and the wiring pins 4 and 5 described above. Detailed description of the structure will be omitted, and the groove 12j formed on the outer periphery in the vicinity of the end (left side in FIG. 11) of the large-diameter portion 12e of the shaft member, which is the biggest difference from each pin, will be described. Now, the arrangement state and function of the jig main body 1 will be described.

  FIG. 11 shows the arrangement state, which will be described below. A predetermined number of through holes 12h are formed at appropriate positions in the jig main body 1, and the anti-spinning pin 12 is press-fitted into the through holes 12h. At this time, the end surface (left end portion in FIG. 11) of the cap 12a is flush with the surface of the plate-like body 1b which is the surface side of the jig main body 1, and the large diameter portion 12e is the jig main body 1. It is in a state of protruding from the surface. In this protruding state, an appropriate urging force is applied by a nut 12d screwed to a threaded portion 12g formed at the end of the spring 12c and the small diameter portion 12f. The distance between the top 12b of the large-diameter portion 12e and the surface of the plate-like body 1b, that is, the protruding length is determined by the specifications of the product plate heater. Furthermore, it goes without saying that it is determined by the specifications of the plate heater, which is a product, including the arrangement position, the number used, dimensions, etc.

  Next, the function will be described. The loss prevention pin 12 is basically used in place of the wiring pins 4 and 5, and therefore has the same function as the wiring pins 4 and 5. As described above, the wiring pins 4 and 5 are disposed on the jig main body 1 in accordance with the set pattern, thereby accurately and reliably arranging the heater wire H, and handling the work. It has a function to make it easy to do. In addition to having such a function, the anti-spinning pin 12 also has a function of preventing the heater wire from being detached from the pin in the handling operation of the heater wire. Here, for easy understanding, the heater wire H is routed with reference to FIG. As the heater wire H, a wire cut by a predetermined dimension in a state of being connected to the lead wire R by a connecting portion is used. First, the connecting portion on one side is prepared so as to be positioned on the elastic body 9, and the one end portion of the lead wire R is fitted to the one lead wire clip 10, and then the wire pins 4, 5 and the blur are connected. The lead pins R are routed around the prevention pins 3, and then the other end portion of the lead wire R is fitted to the other lead wire clip 10 via the adjustment pin 6. At this time, it is confirmed whether or not the connecting portion on the other side is positioned on the elastic body 9, and if it is positioned, the handling work is completed, but it is shifted from the normal position on the elastic body 9. If it is, the adjustment pin 6 is returned again, and the adjustment work different from the previous one is used to carry out the handling work. As a result, the heater wire H is accurately and surely arranged in accordance with the set pattern, and the lead wire R is attached to the lead wire clip 10 in a state where an appropriate tension is provided. Will be disposed. However, in the case of a normal wiring pin, that is, the wiring pins 4 and 5, the large diameter portion 4e is merely a columnar shape. Therefore, in the handling operation, the heater wire H is connected to the wiring pins 4 and 4. May drop out of 5. It is the anti-spin pin 12 that has solved these problems. By using the anti-spin pin 12 instead of the wiring pins 4 and 5, the heater wire H is caught in the groove 12j formed in the large diameter portion 12e. This will prevent the dropout or slipping. It should be noted that it is not necessary to use all the anti-spin pins 12 in place of the wiring pins 4 and 5, and they may be used partially at places where they are easily removed. In short, the wiring pins 4 and 5 and the anti-spinning pin 12 may be properly used as necessary.

  It should be noted that the plate heater manufacturing jig J according to the present invention described so far is only an embodiment, and it is needless to say that various modifications can be made based on the specifications of the product plate heater. Yes, I will add it just in case.

  Subsequently, a method of using the jig for manufacturing a plate heater according to the present invention will be described. Since the method of use is directly related to the manufacture of a plate heater, a product example will be taken up and a method for manufacturing the product example will be described. I will do it.

  Prior to explaining how to use, the type of product will be explained. There are three types of structure. That is, the plate heater 100 shown in FIGS. 13, 14, and 15, the plate heater 200 shown in FIGS. 16 and 17, and the plate heater 300 shown in FIG. As can be understood from FIG. 15, the heater plate 102 is fixed to one surface of the aluminum foil 101a, and the plate heater 100 has a double-sided adhesive tape 101b (adhesive portion 101c + back pattern paper) on the other surface. 101d) is bonded. As can be understood from FIG. 17, the plate heater 200 has an aluminum foil 201a fixed thereto so as to cover the heater wire 202, and a double-sided adhesive tape 201b (adhesive portion 201c + back surface) so as to sandwich the aluminum foil 201a and the heater wire 202. The pattern paper 201d) is bonded. The third type is a plate heater 300 shown in FIG. 18, and is represented by a cross-sectional view corresponding to the section HH in FIG. The plate heater 300 is configured such that the aluminum foil 301a and the aluminum foil 301e sandwich the heater wire 302. One aluminum foil 301a covers the heater wire 302, and the other aluminum foil 301e is formed on the back surface of the other aluminum foil 301e. Is a double-sided adhesive tape 301b (adhesive portion 301c + back pattern paper 301d), which is simply an aluminum sandwich type.

  Also, in the heater wire used, the outer cover is available in vinyl chloride specification type and silicon rubber specification type. In manufacturing, the adhesive used depends on the type of structure and the type of heater wire used. Although there are different points, the above-described product examples, that is, the plate heaters 100, 200 and 300 will be taken up and briefly described.

The plate heater is manufactured by a press device. FIG. 21 shows the press device PL as an extremely simple image diagram. The press apparatus PL is, slide PL ₁ upward is provided so as to move vertically, below, is provided in a state where the bet PL ₃ is fixed. When a motor (not shown) is electrically energized and the switch is turned on, the slide PL ₁ is lowered to press the article on the bed PL ₃ with an appropriate pressure F. PL ₂ is a sponge-like elastic body part, and is used when the aluminum foil is fixed so as to cover the heater wire, in other words, like the plate heater 200 or the plate heater 300 described above, in other words, when it is fixed by drawing. To do. Incidentally, what is placed on the bet PL ₃ is a plate heater for manufacturing the jig J of the present invention.

  Now, a manufacturing method of the plate heater 100 will be described with reference to FIGS. 1 and 21 based on FIGS. 13, 14, and 15. As shown in FIG. 14, the heater wire 102 in which the resistance wire 102a is wound in a spiral shape around the glass core wire 102b and the outside is covered with silicon rubber is set in an arrangement pattern as shown in FIG. It is connected to the lead wire 106 with a connection portion 103 (a connection terminal is molded with heat-resistant silicon rubber) at the lower portion. 104 is a PVC tube, and 105 is a housing. However, since the PVC tube 104 and the housing 105 are not provided at the manufacturing stage, they are excluded from the description.

  In the plate heater 100, the arrangement pattern of the heater wires 102, the size in plan view of the aluminum foil 101a, that is, the length and width, the position of the connecting portion, and the like are determined as specifications. Therefore, it goes without saying that, in the manufacturing jig, each pin member such as a guide pin and a wiring pin is appropriately arranged in accordance with the specification of the plate heater 100.

First, to set the manufacturing jig on place bed PL ₃ of the press PL. Then, the lead wire 106 on one side is fitted on the lead wire clip 10 on one side, and the connecting portion 103 (left side in FIG. 13) is positioned on the elastic body 9, and the cloth properly disposed. The lead wire 106 is routed along the wire pin and the adjustment pin, and the other side connecting portion 103 (right side in FIG. 13) is positioned on the elastic body 9, and then the lead wire 106 on the other side is connected to the lead on the other side. Fit to the line clip 10. Thus, the routing of the heater wire 102 is completed. In other words, in the case where the terminal portion of the heater wire 102 is not at a predetermined position but is disconnected from the elastic body 9, the heater wire 102 is connected. It will return to the adjustment pin and it will be handled again. As for the handling state of the heater wire 102 performed in this way, since the anti-shake pins are appropriately arranged, the heater wire 102 is accurately and surely arranged according to the set pattern without bulging or shaking. Will be. When the handling operation of the heater wire 102 is finished, the aluminum foil 101a is set. The setting of the aluminum foil 101a is completed by placing the outer peripheral portion of the aluminum foil 101a inside each guide pin and pressing it lightly. In addition, since the height of the guide pin is set higher than that of the other pin members, the setting operation is extremely simple. When the setting of the heater wire 102 and the aluminum foil 101a is completed, the operation shifts to pressing.

At setting the heater wire 102 and the aluminum foil 101a in the manufacture jig, whereupon ON the press apparatus PL, slide PL ₁ is lowered, while pushing the guide pin or the like each pin member, presses the aluminum foil, heater wire 102 The aluminum foil 101a is fixed. At this time, in the type of the plate heater 100, a hot press in which the slide PL ₁ side has a constant temperature is used. This is because the heater wire 102 and the aluminum foil 101a are in line contact and there are few contact surfaces, so that a normal adhesive or pressure-sensitive adhesive has a weak fixing force. Therefore, the surface of the aluminum foil 101a on the side of the heater wire 102 is coated with a heat welding member such as silicon, and the covering portion of the heater wire 102 is also formed of a heat welding member such as silicon rubber. Thereby, the heater wire 102 and the aluminum foil 101a are securely fixed. And manufacture is completed by adhering the double-sided adhesive tape 101b to the back surface of the aluminum foil 101a in the integrated heater wire 102 and the aluminum foil 101a. In the hot press, the stopper plate 7 (see FIG. 1) not only simply regulates the lowered position of the slide PL ₁ but also has a function of preventing the adhesive on the aluminum surface from being excessively melted. Yes. The excessive melting of the adhesive adversely affects the fixing state of the heater wire 102 and the aluminum foil 101a. Therefore, in the plate heater manufacturing jig according to the present invention, the pin member is also improved. Still further, the In hot pressing, the use of a sponge-like elastic body PL _2, there is no need, to be placed in additional remark.

3 and 4, the pin P is described as another embodiment. Silicon is deposited and fixed in a circular arc shape on the tip of the large-diameter portion P ₅ of the shaft member. and those with P _8, is obtained by a peak portion P ₉ also the tip of the large diameter portion P ₅ is processed into a conical shape. In the shaft member of the pin in this embodiment, the contact area between the slide PL ₁ and the tip of the large-diameter portion P ₅ during press working is reduced, and heat conduction from the slide PL ₁ can be suppressed. Therefore, the temperature rise of the entire pin including the shaft member is suppressed, and as a result, the adhesive is prevented from being excessively melted, and the fixing of the heater wire 102 and the aluminum foil 101a is ensured. Further, in the embodiment in which the distal end portion of the large diameter portion P ₅ of the shaft member and the silicon up section P _8, consists low thermal conductivity of silicon, to further suppress the Atsushi Nobori of the entire pin including a shaft member The effect of preventing the adhesive from being excessively melted will be improved. And in order to make it easy to take out the product after press working, it is considered that the surface of the jig body 1 is applied with a silicon resin having a peeling effect or embossed.

  Next, a method for manufacturing the plate heater 200 will be described with reference to FIGS. 16, 17, and 21. The arrangement pattern of the heater wire and the plan view shape of the aluminum foil in the plate heater 200 are as shown in FIG. 16, and the manufacturing jig to be used is arranged in accordance with these specifications. Needless to say, each pin member such as a pin, stopper plate, elastic body, lead wire clip and the like are properly disposed.

Beds PL ₃ above position of the press PL, and set the manufacturing jig, handling the heater wire 202, and although to set the rear aluminum foil 201a, the work is the same as the plate heater 100 described above Since there is, explanation is omitted. At the stage of finished sets of heater wire 202 and the aluminum foil 201a, Then ON the press apparatus PL, slide PL ₁ is lowered, while pushing the guide pin or the like each pin member, the aluminum foil was pressed, heater wire 102 and the aluminum The foil 101a is fixed. At this time, since the sponge PL ₂ is attached to the slide PL ₁ , the aluminum foil 201 a is fixed in a state in which the heater wire 202 is wrapped, that is, in a drawn state. In this method, since the contact area between the aluminum foil 201a and the heater wire 202 is increased, normal pressing may be used instead of hot pressing, and the aluminum foil 201a has an acrylic adhesive on the surface to which the heater wire 202 is fixed. It is good to use what the agent adhered. Manufacturing is completed by attaching the double-sided adhesive tape 201b to the integrated heater wire 202 and aluminum foil 201a so as to sandwich the heater wire 202.

  Next, a method for manufacturing the plate heater 300 will be described with reference to FIGS. In addition, since the operation | work of the heater wire 302 and the setting operation | work of aluminum foil are the same as that of the plate heaters 100 and 200 already demonstrated, only a different part will be demonstrated as description is abbreviate | omitted.

At the stage of finished sets of heater wire 302 and the aluminum foil 301a, Then ON the press apparatus PL, slide PL ₁ is lowered, while pushing the guide pin or the like each pin member, presses the aluminum foil 301a, the slide PL ₁ With the attached spongy elastic body PL2, the aluminum foil 301a is fixed in a state where the heater wire 302 is wrapped, that is, in a drawn state. Thereafter, the aluminum foil 301e is fixed so as to sandwich the heater wire 302 with the aluminum foil 301a, and the double-sided adhesive tape 301b is attached to the back surface of the aluminum foil 301e, and the manufacturing is completed. The plate heater 300 has a heater wire 302 sandwiched between aluminum foil 301a and aluminum foil 301e, and it is advantageous to use an aluminum foil with an acrylic adhesive.
