Abstract

PROBLEM TO BE SOLVED: To absorb the plate thickness deviation or curvature irregularity of a plate-shaped object by the deformation of an energizing member by integrating a pressure bonding member with the peripheral edge part of a molded object while relatively moving the same to the plate-shaped object in such a state that the single surface of the peripheral edge part of the plate-shaped member is pressed to the reference surface provided to the pressure bonding member. SOLUTION: The cavity part of a pressure bonding member 20 has a cross section almost coinciding with the cross-sectional shape of a frame member 17 and a molded object 16 is integrated with the entire periphery or part of the peripheral edge part of the plate-shaped object 22 inserted in the inlet part of the cavity part by the relative movement of the pressure bonding member 20 and the plateshaped object 22. Upper and lower roller 38 are provided up and down so as to hold the slit 20A of the pressure bonding member 20 therebetween and the interval between the rollers is set so as to be slightly larger than the thickness of the plate-shaped object. Therefore, the peripheral edge part of the plate-shaped object passing through the cavity part of the pressure bonding member 20 is pressed downwardly along with the pressure bonding member 20 by the energizing force of a spring 35B and the upper surface of the plateshaped object 22 is always brought into contact with the tumbling surface 36A of the roller 36.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a plate-like body with a resin frame suitable for a glass window for a vehicle or a glass window for a building.

[0002]

2. Description of the Related Art In vehicle and architectural window glasses, a gap between a plate-shaped member such as a glass plate and a plastic plate and an opening into which the plate-shaped member is fitted is to enhance decorativeness or sealing property. It is common practice to attach a resin frame such as a synthetic resin molding or gasket.

Conventionally, the mounting of the resin frame has been performed by fitting a frame formed in advance to the peripheral portion of the plate-like body with an adhesive therebetween. However, these methods have a problem that it is difficult to automate the process because there are many parts relying on humans, and the number of processes is large and the cost is high. In order to solve this problem, a synthetic resin material or a raw material thereof is injected into a cavity space in a mold in which a plate-shaped body is arranged, and a synthetic resin frame is integrally formed on a peripheral portion of the plate-shaped body. (Japanese Patent Application Laid-Open Nos. 57-158481 and 58-158481).
No. 73681).

In the encapsulation method, a plate-like body is sandwiched in a rigid mold such as a metal or the like, and a synthetic resin material or its raw material is injected into a cavity space formed by a peripheral portion of the plate-like body and an inner surface of the mold. Therefore, there is an advantage that the number of hands during molding is small and the dimensional accuracy of the product is high. On the other hand, when the plate-like body is a glass plate, there is a problem that the glass plate is very easily broken at the time of mold clamping, particularly due to the warpage of the glass plate and insufficient precision in bending down. In order to prevent the glass plate from cracking at the time of the mold clamping, an elastic body is disposed on a contact surface with the glass plate in the mold, or a mold devised to press the glass plate at a constant pressure using a means such as a spring. As can be seen, the problem of cracking the glass plate has not been solved.

[0005]

The problem to be solved by the present invention is disclosed in
No. 93643 discloses that a resin material is extruded in a predetermined shape by a die along a peripheral portion of a glass plate.
A method has been proposed in which a molded body of a resin frame is formed on a peripheral portion of a glass plate, the formed body of the resin frame is cured, and the glass plate and the resin frame are integrated.

In the method disclosed in the above publication, the resin material is extruded directly onto the glass plate, so that the vibration caused by the vibration of the die is transmitted to the formed body at the time of molding, and is directly reflected on the surface of the frame to be molded. Has the disadvantage of causing poor appearance. On the other hand, Japanese Patent Application Laid-Open No. 57-158479 proposes a method in which, immediately after extruding a resin frame, the resin frame is fitted to the peripheral portion of the plate-like body by a crimping jig composed of a roller or the like and pressure-bonded. I have. In this method, compared to the method described in JP-A-3-193643, the vibration caused by the driving of the extruder or the glass plate is not reflected on the surface of the frame, and poor appearance is less likely to occur.

However, according to the method described in Japanese Patent Application Laid-Open No. 57-158479, the frame is pressed against the glass plate by a pressing jig such as a roller. Will be imitated. Many glass sheets for vehicles are usually bent, and the outer dimensions of the glass sheet may vary during bending. According to the encapsulation method described above, the resin frame can be molded so as to absorb the variation in the outer peripheral dimension.
According to the method described in Japanese Patent No. 479, it is difficult to absorb such variations for the above-described reason.

Further, in the method described in Japanese Patent Application Laid-Open No. 57-158479, it is necessary to fit the frame into a glass plate in a state where the frame is solidified to some extent in order to perform pressure bonding with a roller. On the other hand, in a state where the frame is solidified to a certain extent, the adhesive strength between the frame and the glass plate is weakened. Therefore, it is necessary to separately provide an adhesive between the frame and the glass plate or to add a post-heating step. There is.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a novel method for manufacturing a plate with a resin frame, which solves the above-mentioned disadvantages of the prior art.

[0010]

According to the present invention, in order to achieve the above object, a resin material for a frame is extruded from a resin molding die in a predetermined shape to form a molded body of a frame, and the molded body is molded. In a method for manufacturing a plate-shaped body with a resin frame to be integrated with a peripheral portion of the plate-shaped body, a pressure-bonding member having a hollow portion substantially matching the cross-sectional outer shape of the frame is positioned at a predetermined distance from the molding die. The molded body extruded from the molding die is advanced to the cavity of the crimping member, while the peripheral edge of the plate is inserted into the cavity, and the plate is placed on the reference surface provided in the crimping member. While pressing one side of the peripheral edge of the plate-shaped body, the molded body is moved to the peripheral edge of the plate-shaped body while relatively moving the pressure-bonded member with respect to the plate-shaped body such that the pressure-bonded member follows the peripheral edge of the plate-shaped body. It is characterized by being integrated.

According to the present invention, the molded article extruded from the resin molding die is allowed to pass through the cavity of the crimping member while passing the peripheral portion of the plate-shaped body through the cavity of the crimping member. To the periphery of The peripheral portion of the plate-like body passes through in a wavy state due to a shape error such as a thickness deviation and a variation in curvature thereof while the pressure-bonding member passes through the hollow portion. For this reason, the peripheral portion of the plate-like body does not pass on the predetermined trajectory, and the integrated frame has a problem such as poor appearance and breakage of the plate-like body.

In order to prevent such a problem, in the present invention, the reference member and the urging member are provided on the pressure-bonding member.
Thus, even if the peripheral edge of the plate-shaped body does not pass on a predetermined locus, the position of the pressure bonding member follows the passing position of the peripheral edge of the plate-shaped body. For this purpose, it is desirable to determine the movement trajectory of the plate-like body in advance so that the peripheral edge of the plate-like body moves more on the reference plane side in anticipation of the shape error of the plate-like body.

Thus, for example, when the reference surface is selected on the side facing the upper surface of the plate-like body, and when the peripheral edge of the plate-like body is located below a predetermined position, the influence of the urging member is exerted. Instead, the peripheral portion of the plate-like body can pass through the inside of the cavity of the crimping member. Conversely, when the peripheral edge of the plate-shaped body is located above the predetermined position, the position of the pressure bonding member moves upward following the peripheral edge of the plate-shaped body against the urging member.

Therefore, the peripheral portion of the plate-like body does not pass in a wavy state and always passes through a certain position in the cavity of the pressure-bonding member. Since the variation can be absorbed by the deformation of the biasing member, it is possible to prevent poor appearance of the frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a method for manufacturing a plate-like body with a resin frame according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of an apparatus to which the method for manufacturing a plate-like body with a resin frame of the present invention is applied. An apparatus 10 for manufacturing a plate-like body with a resin frame shown in FIG.
The resin material for a frame is extruded by a molding die 14 attached to the tip of the second 2 to form a molded body 16 of a frame having a predetermined shape. The molded body 16 is picked up by the chuck 19 (see FIG. 6) of the take-up machine 18, and then advanced toward the crimping member 20 by the take-up machine 18, and the cavity 21 of the crimping member 20 (see FIGS. 4 and 5). Is inserted through.

The plate 22 is suction-held by a driving robot 24. By driving this driving robot 24,
The peripheral portion of the plate-like body 22 is inserted into the hollow portion 21 and the crimping member 2
By moving the plate-shaped body 22 so that the O moves relatively along the peripheral edge of the plate-shaped body 22, the molded body 16 and the plate-shaped body 22 are integrated when passing through the hollow portion 21 of the crimping member 20. To

When the compact 16 is not sufficiently solidified when the compact 16 passes through the cavity 21 of the crimping member 20, the surface of the compact 16 (ie, the cavity 2) is formed by the crimping member 20.
(A contact portion with the inner wall of the first device) may have poor appearance. Therefore, it is preferable that the surface layer portion of the molded body 16 be solidified so as not to cause surface roughening and shape change when reaching the pressure bonding member 20.

For this purpose, it is desirable to adjust the distance between the molding die 14 and the pressure-bonding member 20 according to the temperature and viscosity of the molded body 16 to be extruded. On the other hand, if the joint between the molded body 16 and the plate-like body 22 (the inner surface of the biting portion of the molded body 16) is solidified, the adhesive force between the molded body 16 and the plate-like body 22 can be sufficiently obtained. Absent. Therefore, it is preferable that only the surface layer portion of the molded body 16 is solidified, and the joint between the molded body 16 and the plate-like body 22 is not solidified. Therefore, after the extrusion of the molded body 16 and before the molded body 16 reaches the crimping member 20,
It is preferable to rapidly cool the surface layer of the molded body 16.

Specifically, when the resin material for the frame is a thermoplastic resin, only the surface layer portion of the molded body 16 is solidified by blowing cold air onto the surface of the molded body 16 or spraying a liquid. be able to. Among them, it is preferable to spray liquid nitrogen or the like in view of the fact that the surface portion of the molded body 16 can be cooled in a short time. These spraying means may be disposed between the forming die 14 and the crimping member 20 or may be provided at the entrance of the crimping member 20.
Any material can be used as long as the surface of the molded body 16 can be cooled to such an extent that the appearance of the molded body 16 does not deteriorate.

In this way, by setting the surface of the molded body 16 at a lower temperature than the joint of the molded body 16 with the plate-like body 22, the molded body 16 integrated with the plate-like body 22 is formed.
The adhesion between the molded body 16 and the plate-like body 22 can be sufficiently obtained without impairing the appearance of the (frame body 17). In the case of a thermoplastic resin, especially a polyvinyl chloride resin, an extruder 12
Is about 140 to 190 ° C.,
Surface temperature from this temperature to 130 ° C or less, especially 90 °
By cooling to C or less, a plate-shaped body with a resin frame can be manufactured with high productivity.

Further, in order to further improve the adhesive strength between the molded body 16 and the plate-like body 22, before the molding body 16 and the plate-like body 22 are integrated, the peripheral edge of the plate-like body 22 must be removed in advance. It is preferable to perform a primer treatment. FIG. 2 is a schematic sectional view showing this primer processing. As shown in FIG.
With respect to the direction of relative movement with respect to the pressing member 20, the primer applying device 26 is disposed at an appropriate position on the upstream side of the pressing member 20 so that the molded body 16 can be integrated with the movement of the plate-shaped body 22. The primer 28 can be applied to the peripheral portion of the body 22 by a pair of rollers 30, 30. The arrow in the drawing indicates the direction of the relative movement of the plate-shaped body 22 with respect to the pressure-bonding member 20.

FIG. 3 is a perspective view of the periphery of the crimping member 20, FIG. 4 is a longitudinal sectional view of the periphery of the crimping member 20, and FIG. 5 is a cross-sectional view taken along line 5-5 in FIG. 4 and 5, the cross section of the hollow portion 21 of the crimping member 20 substantially matches the cross sectional shape of the frame 17. Then, by the relative movement between the pressure bonding member 20 and the plate-shaped body 22, the entrance 2 of the cavity 21 is formed.
The molded body 16 is integrated with the entire periphery or a part of the peripheral portion of the plate-shaped body 22 inserted into 1A. Reference numeral 21B denotes an outlet of the cavity 21.

In the present embodiment, the cross-sectional shape of the extruded molded body 16 is such that the biting portion (joint portion with the plate-shaped body 22) 32 of the plate-shaped body 22 has a tapered opening side. When the molded body 16 is integrated with both edge surfaces of the plate-like body 22 as in the present embodiment, the plate-like body 22 and the molded body 16 are formed by setting the cross-sectional shape of the extruded molded body 16 to the above shape. Is preferable because the adhesion can be strengthened.

The opening of the biting portion 32 is
A pair of guide claws 34, 3 for opening the mouth which is wider than the plate thickness
4 is disposed at a position where the plate-shaped body 22 enters the biting portion 32, that is, at a position on the preceding stage side of the hollow portion 21 of the crimping member 20. Thereby, the biting portion 32 of the molded body 16
Can be easily bitten into the peripheral portion of the plate-like body 22.

The crimping member 20 is supported by a spring 35A connected to its upper part and a spring 35B connected to its lower part. As these springs 35A and 35B, those having a lower spring 35B whose spring constant is larger than that of the upper spring 35A are used. Therefore, the pressure bonding member 20 is supported in a state of being urged downward by the urging force of the spring 35B.

The pressing member 20 is provided with an upper roller 36 and a lower roller 38 as reference members. The upper roller 36 and the lower roller 38 are provided vertically above and below the slit 20 </ b> A of the pressing member 20. The upper roller 3
6 is a shaft 4 fixed to the crimping member 20 as shown in FIG.
0 is rotatably mounted via a bearing 42, and a lowermost rolling surface (reference surface) 36A is provided at a position projecting slightly downward from the upper edge surface 20B of the slit 20A. I have.

The lower roller 38 is rotatably mounted via a bearing 46 on a shaft 44 protruding from the crimping member 20. The interval between the upper roller 36 and the lower roller 38 is
It is set wider than the thickness of the plate-like body 22. Therefore, the peripheral portion of the plate-shaped body 22 passing through the hollow portion 21 of the pressure-bonding member 20 is pressed downward by the urging force of the spring 35B, whereby the upper surface 22A of the plate-shaped body 22 in the drawing is pressed. Are always in contact with the rolling surface 36A of the upper roller 36.

On the other hand, the relative movement between the crimping member 20 and the plate 22 is controlled such that the crimping member 20 moves relative to the plate 22 along the periphery of the plate 22. By making the robot 24 teach the movement in advance and moving the plate-like body 22, it is possible to realize a relative movement whose position is accurately controlled. At this time, the trajectory to be taught by the driving robot is such that the position of the peripheral portion according to the predetermined design dimension of the plate-shaped member 22 is higher than the upper roller 36 in consideration of the shape error of the peripheral portion of the plate-shaped member 22. I have to.

Thus, the upper surface 22A of the plate 22 can be brought into contact with the upper roller 36 even when the peripheral edge of the plate 22 is located below the predetermined design size. As a result, the position of the upper surface 22A of the plate-shaped body 22 is regulated by the upper roller 36 during passage through the hollow portion, and the upper surface 22A always passes through a fixed position with respect to the inside 21 of the peripheral portion of the crimping member 20. .

When the plate-like body 22 is a plate-like body used for a vehicle window, the frame-like plate-like body is fitted into a window opening of the vehicle. At this time, the fit of the framed plate into the window opening depends on the outer periphery (lip) position of the frame portion of the framed plate. For this reason, when the biting portion of the frame to the plate-shaped body reaches the end face of the plate-shaped body, the lip position of the frame portion of the plate-shaped body with the frame depends on the external dimensions of the plate-shaped body. Become. If there is an error in the external dimensions of the plate-like body with respect to a preset dimension, a problem may occur in the accommodation of the frame-like plate-like body in the window opening.

Therefore, as shown in FIG. 5, the end face of the plate 22 having a predetermined dimension and the plate 2
The movement of the plate 22 is taught by the drive robot 24 so that a gap 54 is formed between the plate 32 and the biting portion 32, thereby absorbing an external dimensional error of the plate 22 itself. be able to. That is, when the outer dimension of the plate-like body 22 is larger than a predetermined dimension (design dimension), the above-mentioned gap 54 is reduced or eliminated. The external dimensions of the shape itself are always predetermined dimensions that can fit in the window opening. This is particularly effective at the time of mass production of the framed plate.

This will be described in more detail. When a conventional molded frame is pressed against a plate by a roller or the like, the external dimensions of the plate with the frame completely follow the external dimensions of the plate itself. For this reason, when the plate-shaped body 22 has an outer dimension error as described above, the error is reflected on the outer dimension of the frame-shaped plate-shaped body.

On the other hand, the design dimensions of the plate 22 are instructed in advance by the drive robot 24 (the control device thereof), and the periphery of the plate 22 should be determined based on the design dimensions. The position of the part 22
Of the plate-shaped body 22 so that the position of the peripheral portion of the plate-shaped body 22 always moves to a predetermined position with respect to the crimping member 20.
, The degree of biting of the molded body 16 into the plate-like body 22 differs depending on the plate-like body 22, but with the frame after the molded body 16 is integrated. The external dimensions of the plate are always maintained at a predetermined dimension.

Next, an example of a method of manufacturing a plate-like body with a resin frame according to an embodiment of the present invention will be described with reference to FIG.
First, the frame resin material is extruded from the molding die 14 of the extruder 12, and the extruded frame-shaped molded body 16 having a predetermined shape is extruded.
Is held by the chuck 19 of the take-off machine 18. Then, the compact 16 is pressed by the take-off machine 18 into the hollow portion 21 of the crimping member 20.
The molded body 16 is advanced toward. Then, cool air is blown from the spraying machine 41 onto the molded body 16 to form the molded body 16.
The surface layer of is solidified.

Then, the biting portion 32 of the molded body 16 is inserted through the pair of guide claws 34, 34 so that the biting portion 32
Is wider than the plate thickness of the plate-like body 22. Thereafter, the molded body 16 is inserted into the hollow portion 21 of the crimping member 20 as shown in FIG. At this time, the driving robot 24
As shown in (b), the plate 22 is sucked and held, and the plate 22 is made to stand by at a standby position.

Next, the driving robot 24 is driven so that the peripheral portion of the plate 22 is inserted into the biting portion 32 of the molded body 16 expanded by the guide claws 34, and thereafter, the pressing member The plate-like body 22 is moved so as to be inserted into the hollow portion 21 of 20. At this time, it is preferable that an unnecessary portion of the formed molded body 16 is cut by the cutter 58. Further, a tapered taper plate 56 (see FIG. 1) may be detachably attached to the leading end insertion portion of the plate-shaped body 22 in order to smoothly inject the molded body 16 into the biting portion 32. preferable.

In this way, the plate 22 is moved so that the peripheral edge of the plate 22 moves along the cavity 21 of the crimping member 20, and the molded body 16 is integrated with the peripheral edge of the plate 22. . At this time, the peripheral portion of the plate-like body 22 has the springs 35A, 35B
If the upper roller 36 is not provided, the sheet passes through in a wavy state due to the thickness deviation and the variation in the curvature. When passing in such a state, the upper surface 2 of the plate-like body 22
The deformation of the frame 16 integrated with the 2A (design surface) causes defects such as occurrence of poor appearance and damage to the plate-like body.
In order to prevent such a problem, in the present embodiment,
Assuming that the crimping member 20 has a spring 35A,
The upper surface 22 </ b> A of the plate 22 is always in rolling contact with the upper roller 36.

The peripheral edge of the plate-like body 22 is moved by the driving robot in which the movement trajectory of the plate-like body is taught.
2A passes while being pressed against the rolling surface 36A of the upper roller 36. The urging force of the spring 35 allows the pressing member to move up and down in accordance with the shape of the peripheral portion of the plate-like body 22, and the upper surface 22A of the peripheral portion of the plate-like body 22 does not pass in a wavy state and does not pass therethrough. Since it always passes through a certain position with respect to the hollow portion 21 of the 20, it is possible to prevent the appearance defect of the frame body 17 serving as a design surface. If the rolling surface 36A of the upper roller 36 is preliminarily coated with a fluororesin, the frictional resistance between the rolling surface 36A and the plate 22 is reduced, so that the plate 22 can be moved smoothly. And the plate-shaped body 22 is not damaged by the rolling surface 36A.

After the molded body 16 is integrated with the peripheral portion of the plate-like body 22 in this way, the molded body 16 is finally cut by the cutter 58 on the upstream side of the crimping member 20. As a result, as shown in FIG. 6C, the molded body 16 continuously fed from the molding die 14 and the integrated frame 17 are separated. Thus, the plate-shaped body 22 in which the frame 17 is integrated is manufactured. Further, by moving the formed body 16 by the take-off machine 18, the process can be shifted to the step of integrating the formed body 16 with the next plate-like body 22.

As the take-off machine, in addition to the above,
It is preferable to use a take-up machine having the configuration shown in FIG. That is, at a position on the opposite side of the molding die 14 of the crimping member 20,
Take-off machine 6 having a pair of rollers 60, 62 as shown
4 is arranged. Further, by providing the cutter 66 at the subsequent stage of the take-off machine 64, it is not necessary to provide a rail as shown in FIG. When the peripheral portion of the plate-shaped body 22 is biting into the formed body 16, the formed body 16 is
Since it moves while being integrated with the plate-like body 22 by the relative movement with respect to 0, the pulling by the take-off machine 64 is unnecessary. Therefore, it is preferable that at least one of the upper roller 60 and the lower roller 62 of the roller in FIG.

FIG. 8 is a longitudinal sectional view showing a second embodiment of the crimping member 20, and the same or similar members as those of the first embodiment shown in FIG. The description is omitted. The pressure roller 20 is provided with a lower roller 72. The lower roller 72 is provided with the pressing member 2
It is rotatably attached via a bearing 76 to a shaft 74 protruding from zero. In this example, instead of using the upper roller as the reference surface in the previous example, the upper edge surface 20B of the pressure bonding member 20 is used as the reference surface.

Also in this case, the upper edge surface 20 of the crimping member 20
It is preferable that B is preliminarily coated with a fluororesin. In the present embodiment, the upper surface 22A of the plate-shaped body 22 is the design surface, and the reference surface is the design surface side. However, the reference surface may be reversed. In the present embodiment, the pressing member 20 is moved relative to the peripheral portion of the plate member 22 by moving the plate member 22, but if the pressing member 20 itself is moved on the contrary, You can also move both by adjusting the movement of. The plate-like body 2 extends along the periphery of the plate-like body 22.
This is because it is only necessary that the member 2 and the pressing member 20 move relative to each other. When the pressing member 20 moves, it is necessary to move the forming die 14 or the take-off machine 18, so it is preferable to move only the plate-shaped body 22.

There is no particular limitation on the relative movement speed between the plate 22 and the crimping member 20, and the speed may always be constant. For example, the speed may be increased or decreased at the corners of the plate 22. You can also. In this case, it is desirable to change the extrusion amount of the material in accordance with the increase or decrease in the speed. As the plate-shaped body 22 used in the present invention, in addition to a single glass plate, a laminated glass in which a transparent synthetic resin film is laminated on a laminated glass or a glass plate, a double-glazed glass, or the like, is used as a window for vehicles or buildings. Are appropriately selected and used depending on the use or the like. Further, these glass plates may be subjected to bending, strengthening, functional coating, and the like. In addition to the glass plate, the present invention can also be applied to an organic transparent resin plate called so-called organic glass, a laminate of this and a glass plate, and the like.

As the resin material for the frame in the present invention,
Examples of the material used for extrusion molding include a thermoplastic resin material used by being heated and melted, and a thermosetting or moisture-curable resin material. Examples of the thermoplastic resin material include PVC, a copolymer of vinyl chloride and ethylene, a styrene resin, and an olefin resin. Examples of the thermosetting resin and the moisture-curable resin include urethane resin materials and silicone resin materials. In addition, sol-like vinyl chloride or the like, which is extruded from a molding die, shaped, and then heated to form a molded body, is used.

Of the above, a thermoplastic resin material must be selected in order for the extruded molded body 16 to be solidified only in the surface layer portion and to have excellent adhesion at the joint with the plate-like body 22. Is preferred. A moisture-curable resin material or a thermosetting resin material can also solidify only the surface layer of the extruded molded body 16 by applying moisture or heat only to the surface, but it is difficult to control the degree of solidification. is there. On the other hand, the thermoplastic resin material, by cooling or simply radiating heat,
Since only the portion having a low temperature is solidified, only the molded body 16 can be easily solidified to such an extent that deformation and surface roughness do not occur as described above.

The shape of the frame 17 is appropriately determined according to its use and the like. Therefore, the plate-like body 22 is formed so as to cover only one side, one side and the end face, or the peripheral edge of the plate-like body 22.
A molded body 16 is integrated with both edge surfaces of the molded article 16 in accordance with respective applications and the like. Among them, the production method of the present invention can exert its effect most when the molded body 16 is integrated with both edge surfaces of the plate-shaped body 22. Accordingly, the present invention provides the frame 17
Of the present invention can be improved in appearance, and the external dimensions of the framed plate-like body 22 can be accurately controlled.

[0047]

As described above, according to the method of manufacturing a plate-shaped body with a resin frame according to the present invention, the plate-shaped body and the molded body of the frame are integrated by using a crimping member after extruding the molded body. Therefore, even if there is vibration due to the movement of the plate-like body or the pressure-bonding member, it is possible to prevent the appearance of the frame from being poor.

Further, in the present invention, the reference member and the urging member are provided on the pressing member, and the cavity of the pressing member is pressed in a state where one surface of the peripheral portion of the plate is pressed against the reference surface of the reference member by the pressing member. Since the portion is allowed to pass through, it is possible to absorb a deviation in plate thickness and a variation in curvature of the plate-like body, and to prevent poor appearance of the frame body.

Claims (4)

[Claims] 1. A plate-shaped member with a resin frame for extruding a resin material for a frame from a resin molding die in a predetermined shape to form a molded body of a frame, and integrating the molded body with a peripheral portion of the plate-shaped body. In the method of manufacturing a body, a pressure-bonding member having a cavity that substantially matches the cross-sectional outer shape of the frame is disposed at a position separated by a predetermined distance from the molding die, and the molded body extruded from the molding die is pressed by the pressure-bonding member. The peripheral portion of the plate-shaped body is inserted into the cavity while the peripheral portion of the plate-shaped body is pressed against a reference surface provided on the crimping member. The molded body is integrated with the peripheral portion of the plate-like body while relatively moving the pressure-bonding member with respect to the plate-like body such that the pressure-bonding member is along the peripheral portion of the plate-like body with a resin frame. Production method. 2. The apparatus according to claim 2, wherein the plate-like body is held by a driving robot,
2. The apparatus according to claim 1, wherein the plate-like body is moved along a locus taught by the driving robot in advance, and the crimping member is relatively moved with respect to the plate-like body such that the crimping member follows the peripheral edge of the plate-like body. A method for producing a plate-shaped body with a resin frame according to (1). 3. The trajectory along which the peripheral edge of the plate moves, the peripheral edge of the plate having a predetermined design dimension in view of the shape error of the plate, the peripheral edge of the plate from one side to the reference surface rather than the reference surface. 3. The method for manufacturing a plate-shaped body with a resin frame according to claim 2, wherein the driving robot is taught in advance so as to be located on a side toward the side. 4. A base reference member having a reference surface against which one surface of a peripheral portion of the plate is pressed, and an urging member which presses one surface of the peripheral portion of the plate against the reference surface of the reference member. The method for producing a plate-shaped body with a resin frame according to any one of claims 1 to 3, wherein the pressure-bonded member is used.
