Description

  The present invention relates to a method for manufacturing a window assembly that is used by being attached to a window opening edge of a mounted body such as a vehicle. The present invention also relates to a manufacturing apparatus suitable for carrying out such a manufacturing method.

A window plate made of inorganic glass and a long strip material (sometimes called molding, gasket, frame, etc.) that is used to prevent the sealant that sticks and seals from sticking out of place. Hereinafter, a window assembly (sometimes referred to as a “module window” or a “modular window”) including a “strip member”) is known. Yes. Such strip material is a member that is typically formed by extrusion of various polymeric materials and is mounted along the outer periphery of the window pane.
Such a window assembly is used by being attached to a window opening edge of a mounted body such as a vehicle or a building or a workpiece. For example, Patent Document 1 describes an example of a vehicle window assembly.
JP 2007-118669 A

By the way, the outer dimensions of the window plates for vehicles are not the same for all of the same type of window plates, and some allowable tolerance is recognized between the window plates. For example, when a window plate having a size of about 1.5 m at the lower edge in the lateral direction, about 1.2 m at the upper edge and about 1 m in height is used for a front window (or rear window) of a normal passenger car, the standard A tolerance of about plus or minus 3 mm (that is, about plus or minus 1.5 mm at each of the left and right ends of the reference center) in the lateral direction (lower end edge and upper end edge) with respect to the dimensions is allowed. In addition, a tolerance of about plus or minus 2 mm is allowed in the longitudinal (height direction) size with respect to the reference dimension. A similar tolerance is recognized for a skylight having a size of about 1.2 m in the horizontal direction (vehicle width direction) and about 0.5 m in the vertical direction (front-rear direction of the vehicle body). In particular, an error is likely to occur in the size of a vehicle window plate formed into a curved surface. That is, the variation in the radius of curvature of the curvature can be the main factor in the variation in the window plate outer dimension.
On the other hand, a certain tolerance is recognized because a slight manufacturing error may occur in the window opening on the vehicle body side.

From the above circumstances, when the window assembly is mounted on the window opening edge of the vehicle body, the distance between the window opening edge and the outer peripheral edge (end surface of the outer peripheral edge) of the window plate is different for each vehicle. Specifically, when the dimension of the window opening edge of the vehicle body is the maximum dimension within the allowable tolerance and the dimension of the outer peripheral edge of the installed window plate is the minimum dimension within the allowable tolerance, the distance dimension is the maximum. become. On the contrary, when the dimension of the window opening edge of the vehicle body is the minimum dimension within the allowable tolerance and the dimension of the outer peripheral edge of the installed window plate is the maximum dimension within the allowable tolerance, the distance dimension is minimized. .
Under such circumstances, when a window plate (window assembly) provided with a conventional strip material as described in Patent Document 1 is mounted on the window opening edge of the vehicle body, the window plate is mounted on the vehicle having the maximum spacing dimension. The contact state of a part of the strip material (for example, the shielding lip portion) with the window opening edge differs depending on when the vehicle is mounted on the vehicle having the smallest distance dimension. It is not preferable that the contact state of the strip material is different for each vehicle body because the aesthetics and quality of the window plate assembly between the vehicles may not be maintained. In addition, when the elastic force of the portion that contacts the window opening edge of the strip material is different due to the difference in the distance dimension, the mounting state of the window assembly may be different for each vehicle due to the difference in the elastic force. In some vehicles (for example, in the vehicle having the maximum distance or the minimum distance), there is a possibility that a mounting failure of the window assembly may occur, which is not preferable.

In addition, a dam rubber 8 for preventing the sealant 7 from protruding is provided over the entire periphery of the window plate 12. The sealant 7 is a material that functions as an adhesive that exhibits rubber-like elasticity when cured. For example, those made of urethane resin are preferable. As a result, the window assembly 10 (window plate 12) is attached (fixed) to the predetermined front window frame portion (recessed portion) 4 and attached.

  Hereinafter, a preferred embodiment of the window assembly manufacturing apparatus and the manufacturing method of the present invention will be described with reference to FIGS.

FIG. 6 is a plan view schematically showing the strip material position fixing device 110 which is a main part of the window assembly manufacturing apparatus 100 according to the present embodiment. As shown in this figure, the strip material position fixing device 110 according to the present embodiment is roughly divided into a substantially rectangular table-like gantry 112 corresponding to the outer shape of the window plate 12, and the rectangular gantry 112. Long position adjusting members 120, 130, 140, and 150 respectively attached to the outer edges of the four sides. Hereinafter, the four position adjustment members are referred to as a left position adjustment member 120, an upper position adjustment member 140, a lower position adjustment member 130, and a right position adjustment member 150 on the paper surface of FIG. .
As representatively shown in FIG. 7 which is a cross-sectional view taken along the line VII-VII in FIG. 6, each position adjusting member 120, 130, 140, 150 is fixed to the end edge of the gantry 112 with a bolt 114. . The three position adjusting members 120, 140, 150 excluding the lower position adjusting member 130 are fixed to the gantry 112, and a fixing portion 122 for fixing the positions of the strip materials 20, 40, 50, respectively. A protrusion 123 that protrudes upward at the outer edge is provided, and movable parts 126, 146, and 156 that are rotatably mounted on the protrusion 123 are further provided. On the other hand, the lower position adjusting member 130 includes a fixed portion fixed to the gantry 112 and a protruding portion 133 upward at an outer edge portion of the fixed portion.

  As shown in FIGS. 6 and 7, the three position adjusting members 120, 140, and 150 excluding the lower position adjusting member 130 have movable parts 126, 146, and 156 that are elastic member fixing members according to the present embodiment. At least one location in the longitudinal direction, preferably several locations (in the present embodiment, three locations on the upper position adjustment member 140, left position adjustment member 120 and right position adjustment member 150). In two places, the spring member 116 which is the elastic means according to the present embodiment is fixed by a fixing tool 118 such as a screw or a rivet. Further, the lower position adjusting member 130 may be provided with a movable portion, but in order to simplify the structure, the inner wall surface of the protruding portion 133 having the same height as the movable portions 126, 146, 156 instead of the movable portion. On the side, the spring member 116 is fixed at the same position as the movable portions 126, 146, and 156 with the same fixing tool 118 at at least one place in the longitudinal direction, preferably several places (three places in the present embodiment). Specifically, the spring member 116 according to the present embodiment is a leaf spring material produced by bending both ends of a strip-shaped (rectangular) metal plate into an acute angle in the same direction and forming a substantially C shape. . Thus, by fixing one end of the bent portion to the movable portion 126 (the protruding portion 133 in the lower position adjusting member 130) with the screw 118, as shown in the drawing, the bent portion closer to the screw fixing portion. It can exert its resilience around the center. The elastic means may be a plurality of fluid pressure cylinders having the same inner diameter that operate at the same pressure.

  Further, on the outer wall surface side of the movable portion 126, a rotary hinge portion 128 for fixing the movable portion 126 and the spring member 116 so as to be rotatable in a direction approaching and separating from the outer peripheral edge of the window plate 12 is formed. . As a result, as shown in FIG. 7, the movable portion 126 is reversibly rotated about the rotation center 128A of the rotary hinge portion 128 as an axis (that is, the spring member 116 is retracted from the window plate 12 to a position where it does not come into contact). Can do.

Further, a fixing groove 124 is formed in the longitudinal direction as a means for fixing the strip material 20, 40, 50 on the upper surface of the fixing portion 122 of the three position adjusting members 120, 140, 150 excluding the lower position adjusting member 130. Has been. Specifically, the main body portion fixing groove 124A that fits in a state where the double-sided adhesive tape 32 in which the main body portion 21 of the strip material 20 is attached in advance on the concave groove portion (joining portion) 28 is exposed on the upper surface, and the state thereof And a lip fixing groove 124B for arranging the shielding lip.
With such a configuration, the predetermined mounting position of each strip member 20, 40, 50 when joined to the window plate 12 with the center position of the fixing device 110 according to this embodiment (that is, the center position of the rectangular mount 112) as a reference ( Each strip member 20, 40, 50 can be correctly fixed (arranged) at a predetermined position at a position corresponding to the (ideal position). Note that the separator (release paper) 32A is peeled off from the strip material 20 fixed to the fixing groove 124 before the window plate 12 is moved by the window plate holding and moving device 170 described later and the joining operation is started. At this time, the separator (release paper) 32A can be easily and quickly peeled off by grasping and pulling the tab tape 32B, and the pressure-sensitive adhesive layer located on the side of the window plate 12 of the double-sided adhesive tape 32 can be easily formed. Can be left exposed. A groove is also formed on the upper surface of the fixed portion of the lower position adjusting member 130, and a long material that is softer than the window plate so as to have the same height as the main body portion of the strip material in the groove. Or a soft long material may be attached to the upper surface of the fixed portion.

Next, a window plate holding and moving device 170 included in the window assembly manufacturing apparatus 100 according to the present embodiment will be described with reference to the drawings.
In the present embodiment, the window plate 12 before the strip members 20, 40, 50 are joined is in a different location within the reach of the robot arm, which will be described later, installed near the window assembly manufacturing apparatus 100. It is positioned and placed with reference to an edge adjacent to a predetermined one of the four corners of the rectangle. For example, it mounts on the mounting base (not shown) in which the rod-shaped or block-shaped positioning stopper is provided in the part corresponding to the upper edge part 13 and the left edge part 14 of the window plate 12 of a defined dimension.
Therefore, when a window plate having the same size as the specified size (that is, a window plate having no error with respect to the specified size) is placed on the mounting table, the center position P in the surface direction of the window plate is the center of the mounting table. It coincides with the position P1. On the other hand, when a window plate having a size different from the specified size (that is, a window plate having an outside dimension error with respect to the specified size) is placed on the mounting table, the center position P in the surface direction of the window plate is: It does not coincide with the center position of the mounting table (for example, when there is an error in the outer dimension in the left-right direction, the center position of both is shifted in the left-right direction by one half of the error).
As shown in FIG. 7, the window plate holding and moving device 170 according to this embodiment includes a vacuum sucker (window plate holding member) 172 communicating with an external vacuum pump (not shown). The vacuum suction cup 172 is typically attached to the tip of an articulated robot arm (not shown) via an elastic rubber joint member 174 that is a position adjustment permission mechanism and a rotation permission mechanism.
The joint member 174 only needs to have a function of moving and turning the window plate 12 in a direction parallel to the surface of the window plate 12 within the range of the sum of the error of the outer dimension of the window plate and the error of the robot arm. It is not limited to rubber. Further, if the vacuum suction cup 172 is formed of a soft elastic polymer material such as rubber and has the above function, the suction cup can be shared as a joint member. In addition, the robot arm is electrically connected to another control mechanism (computer control unit), and the robot arm is previously moved (set) between the center position (P1) of the mounting table and the center position of the fixing device 110. According to the trajectory, it is possible to reciprocate repeatedly with a positional accuracy within ± 0.5 mm (± 0.5 mm) in practice. Specifically, as the robot arm moves, the vacuum suction cup 172 attached to the tip of the robot arm sucks the window plate 12 on the mounting table with reference to the mounting table center position (P1), and the sucked state Then, the window plate 12 is moved in the direction parallel to the surface direction of the window plate and in the vertical direction perpendicular to the surface, and conveyed to the center position of the fixing device 110. Furthermore, the window plate 12 can be swiveled in the surface direction. In other words, the window plate 12 attracted and held by the vacuum suction cup (window plate holding member) 172 can be moved in the up-down direction and the left-right direction while turning in the clockwise direction or the counterclockwise direction. Since the window plate 12 has rigidity, it is not deformed or displaced in the middle of conveyance.
Here, as described above, the size from the suction cup position to the outer edge of the window plate differs when the suction plate 172 sucks the window plate without error and when the suction plate with error is sucked. . The rubber joint member (universal joint) 174 is sufficient to absorb the error and allows movement adjustment of the window plate 12 in the surface direction and the turning direction within a range in which the joint member 174 can be elastically deformed. Further, the elastic deformation of the joint member 174 is set so that it can be elastically deformed with a force smaller than the sum of the elastic force of the spring member 116 described later, and the position of the window plate 12 can be moved and adjusted in the surface direction.
As described above, the window plate 12 is transported from the predetermined storage position (the mounting table described above) to the strip material position fixing device 110, and the window plate 12 is placed on the mount 112 of the strip material position fixing device 110. be able to.
Note that the configuration itself of the robot arm whose operation is controlled by the computer control unit is a well-known technique in the industrial machine field, and does not require a special configuration for carrying out the present invention. .

Next, the window plate 12 conveyed by the window plate holding and moving device 170 is correctly placed on the joint portion 28 of the strip material 20, 40, 50 fixed to the position adjusting members 120, 140, 150 on the mount 112. The operational effects (functions) exerted by the plurality of spring members 116 serving as the above-described elastic means will be described in detail. First, before the window plate 12 is conveyed, the movable portions 126, 146, and 156 are rotated and moved to positions indicated by solid lines in FIG. 7 (positions approaching the outer peripheral edge of the window plate 12 that moves later). .
As shown in FIGS. 6 and 7, the spring member 116 according to this embodiment is a surface that faces the outer peripheral edges 13, 14, 15, 16 of the window plate 12 when placed on the gantry 112. When attached to the inner wall surface of the movable portions 126, 146, 156 of the adjusting members 120, 130, 140, 150 (the protruding portion 133 in the lower position adjusting member 130), and elastically contacting the outer peripheral edge of the window plate 12. It arrange | positions so that the elastic force (refer arrow in FIG. 6) may act on the center direction of the window board 12. FIG.

Furthermore, the plurality of spring members 116 according to the present embodiment are arranged such that when the window plate 12 moves and the spring members 116 are in elastic contact with the outer peripheral edges 13, 14, 15 and 16, respectively. Are adjusted so that the elastic force can be applied to the window plate 12 from each direction so that the opposing elastic forces (the total sum) facing each other are the same. Further, when the window plate 12 is moved and each spring member 116 comes into contact with the outer peripheral edges 13, 14, 15, 16 (that is, before the window plate 12 is pushed between the spring members 116), The robot arm is controlled by the control mechanism so that the surface direction is parallel to the strip material 20 on the gantry 112.
In the present embodiment, since the window plate 12 has a rectangular shape, the opposing elastic forces facing the center direction of the window plate 12 are F1 and F2, and F3 and F4 as shown in FIG. is there. Therefore, the total sum (3 × F1) of the resilient force F1 directed toward the center of the window plate 12 by the three spring members 116 provided in the upper position adjusting member 140 is the resilient force opposed to the resilient force F1. F2, that is, the total of the spring force F2 (3 × F2) directed toward the center of the window plate 12 by a total of three spring members 116 provided on the lower position adjustment member 130, is equal to each spring member 116. The resilience has been adjusted. Exactly in the same manner, the total sum (2 × F3) of the elastic force F3 directed toward the center of the window plate 12 by the total two spring members 116 provided on the left position adjusting member 120 is the elastic force facing the elastic force F3. Each spring member 116 has the same force F4, that is, the total sum (2 × F4) of the elastic force F4 directed toward the center of the window plate 12 by the two spring members 116 provided on the right position adjustment member 150. The resilience of has been adjusted.
As a result of the provision of the adjusted spring member 116, when the window plate 12 having the same size as the specified size (a window plate having no error with respect to the specified size) is conveyed, the robot arm is operated as described above. The pedestal 112 surrounded by the four position adjusting members 120, 130, 140, and 150 (the center position P of the window plate 12 coincides with the center position P1 of the mounting table) is accurately adjusted by Further, the window plate 12 is advanced toward the joint portion 28 of the strip material 20, 40, 50 fixed on the gantry 112 (here, the weight of the window plate 12 is used as a pressing force). The elastic force is directed toward the center of the window plate 12 while maintaining the parallel relationship between the surface direction of the window plate 12 and the strip material 20 on the mount 112 when lowered from the upper side to the lower side in the direction of gravity. Opposite Since the generating forces are the same (3 × F1 = 3 × F2, 2 × F3 = 2 × F4), the center position P of the window plate 12 and the fixing device 110 (the gantry 112) are not required to be operated specially. The center position can be matched. Here, when the window plate 12 is lowered and the window plate back surface 12B contacts the double-sided adhesive tape 32, the bonding is performed. At this time, the window plate back surface 12B is bonded to the pressure-sensitive double-sided adhesive by its own weight because the pressure is applied to the double-sided adhesive tape 32, but a downward force may be applied to the robot arm. As shown in FIGS. 6 and 7, the center position P of the window plate 12 and the center position of the fixing device 110 (the gantry 112) coincide with each other from the center position P of the window plate 12 in a plane direction. The strip members 20, 40, 50 can be bonded to the window plate back surface 12 </ b> B with the double-sided adhesive tape 32 at positions accurately separated by a distance (dimension). In other words, the distance between the opposing strip member joined along the opposing outer peripheral edge and the outer peripheral edge of the window plate is always the same in one window plate regardless of variations in the outer dimensions of the window plate (for example, left and right And the same).
On the other hand, when the window plate 12 having a size different from the specified size (a window plate having an outside dimension error with respect to the specified size) has been transferred, the actual center position of the transferred window plate 12 as described above. P and the center position of the fixing device 110 do not match and are different. In this case, the peripheral edge of the window plate 12 is in strong contact with the spring member (elastic member) 116 at one edge, and the opposing peripheral edge is weakly in contact with the spring member 116. Since the sum of the elastic forces of the spring members 116 at one edge is set equal to the sum of the elastic forces of the spring members 116 at the opposite edges, the spring members 116 abut against the window plate 12 weakly from the side that abuts strongly. The force to move toward the side is applied. At this time, as described above, the joint member 174 (universal joint) is set so as to be elastically deformed with a force smaller than the sum of the elastic forces, so that the position adjustment movement of the window plate 12 is permitted. The twelve actual center positions P can be matched to the center position of the fixing device 110.
Thus, even when the window plate 12 having a size different from the specified size (a window plate having an outside dimension error with respect to the specified size) is conveyed, the center position P of the window plate 12 and By aligning the center position of the fixing device 110, the strip members 20, 40, and 50 can be joined at an accurate position.
In the above description, the window plate 12 is sucked and transported by the vacuum sucker 172 provided at the end of the robot arm. However, the window plate 12 is transported manually using a vacuum suction plate or the like. May be. In this case, a robot is not necessary, and the position of the window plate 12 can be adjusted and moved by the joint of the operator's wrist or arm in manual work, and therefore the joint member 174 (universal joint) is not necessarily required.

As described above, according to the window assembly manufacturing apparatus and the manufacturing method of the present invention, even if the dimensions of the outer peripheral edges 13, 14, 15, 16 of the window plate 12 vary within the allowable tolerance range, they are not affected by the variation. (I.e., without being affected by the variation), the strip members 20, 40, and 50 are placed on the back surface of the window plate at positions accurately separated from the center position P of the window plate 12 by a predetermined distance (dimension) in the surface direction. 12B. In other words, the interval between the opposing strip members 20, 40, 50 joined along the opposing outer peripheral edges 13, 14, 16 and the end surface of the outer peripheral edge of the window plate 12 exists for each window plate 12 to be used. Regardless of possible variations in outer dimensions, one window plate will always be the same. For this reason, it is possible to suitably maintain the same aesthetics and quality regarding the window plate assembly between vehicles. Further, since the elastic force to the panel member 2 (the side panel member 3 in FIG. 2) constituting the window opening edge of the strip material 20, 40, 50 does not vary between the strip materials 20, 40, 50, A good wearing state can be realized.
In the three position adjustment members 120, 140, and 150 excluding the lower position adjustment member 130, as described above, the spring member 116 can move forward and backward with respect to the center position P of the window plate 12. The movable parts 126, 146 and 156 of 120, 140 and 150 are mounted. As shown in FIG. 7, a mechanism is provided that prevents the window plate from retreating when the window plate moves forward (lowers) and the spring member 116 elastically contacts the outer peripheral edge of the window plate 12 to apply the elastic force. ing. Specifically, as shown in FIG. 7, the position where the outer peripheral edge of the window plate 12 and the spring member 116 first contact is closer to the fixing portion 122 (rotation) of the position adjustment member 120 than the rotation center 128 </ b> A of the rotation hinge portion 128. The position below the center 128A). Further, the contact surfaces 126A and 123A between the movable portion 126 and the protruding portion 123 are formed to be inclined obliquely downward from the rotation center 128A of the hinge portion 128. For this reason, in this state, the force which pushes back the movable part 126 does not generate | occur | produce. That is, in this state, the movable portion 126 does not rotate backward.
On the other hand, when the window plate 12 is lifted after the joining of the window plate 12 and the strip members 20, 40, 50 is completed, the spring member 116 that contacts the outer peripheral edge of the window plate 12 is lifted upward. A force such as a frictional force acts, and as a result, the movable portion 126 rotates backward (that is, the spring member 116 moves backward away from the window plate 12). Thereby, the separation of the window plate 12 from the gantry 112 (fixing device 110) is performed smoothly. However, after the joining is completed, the movable portion 126 may be rotated backward by applying a forcible force before the window plate 12 is raised.
Note that the separation operation can be performed more smoothly by coating the surface of the spring member 116 with an appropriate lubricant that is softer than the spring member in advance (that is, forming a lubricating film). Further, it is possible to prevent the outer periphery of the window plate 12 from being damaged due to contact (elastic contact) with the spring member 116. Further, although the spring member 116 is made of a metal plate, it may be formed of a resin material that is easily elastically deformed. Thereby, generation | occurrence | production of the crack etc. by the contact with the window board 12 can be prevented further.

As described above, the window plate assembly 10 after the strip materials 20, 40, 50 are bonded to the predetermined position (bonded portion 17A) on the back surface 12B side of the window plate 12 is removed from the strip material position fixing device 110. After that, in order to realize stronger bonding between the bonded portion 28 and the bonded portion 17A, the transferred portion is conveyed to a separately prepared heating and pressurizing device 180. Hereinafter, the heating apparatus and pressurizing means according to the present embodiment will be described with reference to FIG.
FIG. 8 is a side view schematically showing a main part of the heating device 180 according to the present embodiment. As shown in the figure, the heating device 180 according to the present embodiment is roughly formed in a rectangular table-like frame 181 and a frame shape corresponding to the shape of the window assembly 10 on the frame 181. And an assembly mounting frame 182. With this configuration, as shown in the figure, the window assembly 10 can be placed on the assembly placement frame 182 so that the strip members 20, 40, 50 are on the upper surface side.

As shown in the figure, the assembly mounting frame 182 of the heating device 180 is equipped with various devices used when performing the heat treatment.
Specifically, the heater 183 according to the present embodiment has a position (preferably a strip material) corresponding to a position where the strip materials 20, 40, 50 are arranged when the window assembly 10 is placed on the frame 182. A heater 183 equipped with a long infrared heater 184 surrounded by a jacket 185 made of a heat insulating material is provided almost immediately below the position where the 20, 40, 50 are arranged. A transparent window 188 that transmits infrared rays is provided above the infrared heater 184 (that is, between the infrared heater 184 and the window plate 12) to protect the heater 184.
A temperature sensor 186 for detecting the temperature of the frit layer 17 of the window assembly 10 is installed at a position close to the heater 183 (infrared heater 184). The temperature sensor 186 according to the present embodiment is a non-contact type infrared sensor, but is not limited to this type. For example, a contact sensor using a thermocouple or a thermistor may be used.
Further, it detects that the window assembly 10 is placed on the frame 182 (turns on (ON) when placed from the window assembly, and turns off (OFF) when removed). A detection sensor 187 is provided. The window plate detection sensor 187 according to the present embodiment is a push button type detection switch having a simple structure, but is not limited to this type.

  As shown in FIG. 8, the heater 183 (infrared heater 184), the temperature sensor 186, and the window plate detection sensor 187 are configured by a control device (typically a microcomputer unit provided with a CPU or the like) 190 provided on a base 181. And the cables 191, 192, and 193, and heat treatment can be preferably performed based on a control signal from the control device 190. Typically, the window assembly 10 in which the strip material 20 is bonded to a predetermined position (bonded portion 17A) inside the frit layer 17 on the back surface side of the window plate 12 as described above is used as an assembly mounting frame. When placed at a predetermined position 182, the push button of the window plate detection sensor 187 protruding on the frame 182 is pushed by the placed window plate (an ON state indicated by a solid line in FIG. 8). . As a result, a detection signal indicating that the window assembly 10 has been placed is input to the control device 190, and the heating program is started. Specifically, the infrared heater 184 is energized by a control signal from the control device 190, far infrared rays are irradiated to the surface 12 A side of the window plate 12 through the transparent window 188, and the radiant heat transmitted through the window plate 12. As described above, the joined portion between the joined portion 28 and the joined portion 17A can be heated. By adopting such heating by radiant heat, the pressure-sensitive adhesive layer can be appropriately heated to a temperature (practically 40 ° C. to 80 ° C.) at which a preferable bonding force is obtained.

  In the heating device 180 according to the present embodiment, the heating state of the joint portion can be constantly monitored by the temperature sensor 186. That is, the temperature sensor 186 detects the temperature of the frit layer 17 heated by heat conduction from the joint portion, and the temperature detection signal is input to the control device 190. Here, when a temperature higher than a preset heating temperature is detected, the control device 190 determines that the heating process has been completed, and the energization of the infrared heater 184 is terminated by a control signal from the control device 190. To do. Then, by removing the window assembly 10 that has been heated from the frame 182, the push button of the window plate detection sensor 187 is released (indicated by a chain line in FIG. 8), and the heating program is reset. In this way, the plurality of window assemblies 10 can be heated under the same conditions (the above heating program).

Preferably, the pressure treatment is performed simultaneously with the heating. For example, by using a pressurizing apparatus 200 as shown in FIG. 8, a bonded portion heated to a temperature preferable for adhesion can be pressed well. In the present embodiment, the illustrated pressurizing device 200 is a roller device that pressurizes a target portion by the operator's own hand or by a robot arm. Specifically, a pressing compound roller 204 having a plurality of independently rotating rollers coaxially overlapped with a rotating shaft 203 provided on a frame 202 connected to the gripper 201 is rotatably attached. Yes. As shown in the drawing, the step shape of the pressing surface of the pressing composite roller 204 corresponds to the step on the bottom surface of the strip material 20, and further, the side surface of the strip material 20 is held by the flange portion 204A in the lateral direction. Prevents deviation. Furthermore, since each roller rotates independently, the rotational angular velocity of each roller can be made different and the peripheral speed can be made the same.
As a result, the longitudinal direction of the strip material is applied while pressing the roller 204 against the bottom surface of the strip material without distorting the predetermined shape of the strip material 20 and applying a predetermined pressure from the gripping portion 201 side as shown in the figure. It is possible to press the strip material 20 in a state in which each roller maintains the same peripheral speed and is pressed over the entire length of the strip material to the window plate side. Thereby, better bonding can be realized.

The preferred embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made to the technology described in the claims. included.
For example, the strip material position fixing device 210 shown in FIG. 9 is a modified example of the above-described strip material position fixing device 110 shown in FIG. 7, and the configuration of the movable portion 226 and the movement mode of the spring member 116 associated therewith (advance and retreat). Embodiment) is different. Hereinafter, the strip material position fixing device 210 according to the modified example (second embodiment) will be described with reference to the drawings. The members having the same functions as those of the fixing device 110 according to the first embodiment shown in FIG. 7 described above are denoted by the same reference numerals, and redundant description will not be given. Although only the left side position adjusting member 220 is shown in FIG. 9, the same configuration is applied to the upper, lower, and right side position adjusting members (not shown).

As shown in FIG. 9, in the strip material position fixing device 210 according to the present embodiment, the position adjusting member 220 attached to each outer peripheral edge of the rectangular table-like pedestal 112 has several longitudinal positions (for example, the first embodiment). In the same manner as in the embodiment, three positions are provided for the upper position adjustment member and the lower position adjustment member, and two positions for the left position adjustment member 220 and the right position adjustment member), and outward of the fixing portion 222 (to the side of the strip material fixing groove 224). An extending slide rail 223 is formed. On the slide rail 223, a movable portion 226 according to the present embodiment is mounted so as to be slidable in the forward and backward directions along the slide rail 223. The same spring member 116 as that of the first embodiment is fixed to the inner wall surface of the slide movable part 226 (that is, the center side of the gantry 112) with screws 118. On the other hand, an outer wall surface of the slide movable unit 226 is connected to a fluid pressure cylinder (typically a pneumatic cylinder) 230 connected to an external cylinder drive source (not shown).
