Description

Description Primer coating device for glass plate Technical field

The present invention relates to an apparatus for applying a primer liquid to a glass plate, which coats a primer liquid around a main surface of a glass plate. Background art

Some automotive window glasses have a resin molding around a glass plate. Generally, this resin molding is formed around the glass plate by injection molding, but it is difficult to attach the resin molding directly to the surface of the glass plate in a favorable manner.

Therefore, before the resin molding is injection-molded, an adhesive is applied to the periphery of the glass plate (hereinafter, referred to as “primer treatment”), and the resin molding is injection-molded on the surface of the adhesive to form a glass plate. Resin molding is satisfactorily attached to the surface with an adhesive.

Although the description has been given of the window glass for an automobile as an example of performing the primer treatment, the primer treatment is applied not only to the window glass for an automobile but also to a glass plate for a solar cell and the like.

As an apparatus for performing such a primer treatment, for example, a coating apparatus disclosed in Japanese Patent Application Laid-Open No. 11-347470 is known. This conventional method of applying a primer for a glass plate is shown in FIGS. 15A and 15B.

Fig. 15A shows that the primer liquid is applied to the two opposite sides 1101, 102 of the glass plate 100 with a constant application width W1, and the primer is applied to the other two sides 103, 104 with a constant application width W2. Shows the state where the liquid was applied.

In the primer liquid application device 105 shown in FIG. 15B, the back surface of the main body 106 is divided into two surfaces by a guide plate 107, and a first application member 108 (application width W1) is provided on one back surface, and the other is provided. The second application member 109 (application width W2) is provided on the back surface.

In this primer liquid coating device 105, the second coating member 109 is brought into contact with the periphery of the glass plate 100, and the guide plate 107 is brought into contact with the end face 100 a of the glass plate 100. While supplying the primer liquid from the second liquid supply pipe 1 1 1 to the coating member 109, the primer liquid By moving the device 105 along the periphery of the glass plate 100, the primer liquid is applied to the periphery of the glass plate 100 with a coating width W2.

On the other hand, the first coating member 108 is brought into contact with the periphery of the glass plate 100, and a guide plate is brought into contact with the end surface 100a of the glass plate 100. In this state, the first liquid supply pipe is brought into contact with the first coating member 108. The primer liquid is applied to the periphery of the glass plate 100 with a coating width W1 by moving the primer liquid coating device 105 along the periphery of the glass plate 100 with a robot or the like while supplying the primer liquid from 110. I do.

Usually, there is a case where it is desired to change the application width of the primer treatment on each side or within each side of the glass plate 100. This is illustrated in Figure 16.

FIG. 16 is a plan view showing a state where a conventional glass plate is subjected to a primer treatment. The glass plate 100 shown in FIG. 16 has a coating width of W3 on the left side 100a, a coating width of 100b on the right side 100b, a coating width of 100c on the upper side 100, and a coating width of 100 on the lower side W6 and W7. Here is an example with two widths.

In some glass plates, it is desired to change the coating width only on one side such as the left side.

As described above, when the coating width of the glass plate 100 is made different for each side, or when it is desired to change the coating width to W6 or W7 within 1 OOd of the lower side, the conventional primer liquid coating apparatus 105 cannot cope. Can not.

For this reason, the coating width of the primer liquid can be arbitrarily changed so that the coating width of the glass plate 100 can be different for each side, and the coating width can be changed even within only one side. Practical application of a primer liquid coating device that can be used has been desired.

When the primer liquid applicator 105 is moved by a robot, the trajectory of the primer liquid applicator 105 is determined in advance by teaching, and the force applied to the trajectory determined by the teaching is adjusted. The primer liquid is applied along the periphery of the glass plate 100 by moving.

However, when the primer liquid coating device 105 is moved by a robot, if the coating surface of the glass plate 100 is shifted due to, for example, a manufacturing error of the glass plate 100, there is a risk that the primer liquid may be coated by shifting from the regular coating surface. is there. For this reason, there is a demand for a practical application of a high-precision primer liquid coating apparatus capable of reliably applying a primer liquid to a regular coating surface.

1 and 2 show a window glass G for an automobile on which a resin molding 17 is provided. The window glass G is provided at the periphery of the outer surface 11 of the glass plate 10, that is, at the periphery of the outer surface (main surface edge) 12, at the periphery of the end surface 13 and the inner surface 14, that is, at the periphery of the inner surface (main surface). After applying the primer liquid 16 to each of the end parts 15, these primer liquids 16 were applied with a coating width W (outer peripheral part 12, end face 13, and inner peripheral part 15). It is obtained by injection molding a resin molding 17 so as to cover the resin molding.

The resin molding 17 is formed on the glass plate 10 by injection molding the resin molding 17 on the application surface (the outer peripheral portion 12, the end surface 13 and the inner peripheral portion 15) on which the primer liquid 16 has been applied. Join.

Hereinafter, a primer liquid application device for a glass plate, which applies the primer liquid 16 to the outer peripheral portion 12, the outer peripheral surface 13 and the inner peripheral portion 15 of the glass plate 10, based on FIGS. 3 to 6. explain.

Referring to FIG. 3, the primer liquid application device 20 for glass plate has a stand 22 on a base 21, and an upper application mechanism 25 is swingable up and down around a support shaft 28 near an upper end 23 of the stand 22. And a lower coating mechanism 26 is mounted substantially at the center of the stand 22 so as to be swingable up and down around a support shaft 28. The upper coating mechanism 25 applies the primer liquid to the outer peripheral portion 12 of the glass plate 10. The lower coating mechanism 26 applies the primer liquid to the end surface 13 and the inner peripheral portion 15 of the glass plate 10.

The upper coating mechanism 25 includes a swing member 30 that is swingably attached to the stand 22 via a support shaft 28, and a tension spring (second attachment) that is attached to the swing member 30 and biases the swing member 30 clockwise. A holding member 32 provided on the swing member 30 so as to be movable in a direction approaching and away from the end surface 13 of the glass plate 10, a liquid applying member 33 attached to the holding member 32, and an end surface contact. A member 34 and a cylinder unit 35 for changing the position of the end face contact member 34 are provided.

The glass plate 10 is positioned at the primer liquid application position by being sucked by the suction pad 19 of the robot 18. Next, FIGS. 4 to 6 are collectively referred to. The support member 37 is attached to the upper end 23 of the stand 22, the upper end 31 a of the tension spring 31 is hung on the pin 39 provided at the tip 38 of the support member 37, and the pin provided at the rear end 30 a of the swing member 30. Hang the lower end 3 1 b of the tension spring 3 1 on 41. The bow I tension spring 31 urges the swing member 30 clockwise about the support shaft 28.

A holding plate 43 is attached to a front end 30b of the swing member 30 via a shaft 42. The holding plate 43 has connecting portions 44 at both ends.

The connecting portions 44, 44 have screws L45, 45. The threaded ends 45, 45 are screwed with threaded ends 47, 47 of connecting rods 46, 46, respectively.

The slide plate 50 of the holding member 32 is attached to the pair of connecting rods 46,46. The base end 52 of the support piece 51 is fixed to the upper part of the slide plate 50 with a bolt 53. The liquid application member 33 is fixed to the tip end 54 of the support piece 51 with bolts 56, 56.

The support piece 51 has a pair of through holes 52a, 52a (only the near side is shown in FIG. 5) formed at the base end 52 thereof.

The slide plate 50 is a plate formed in a substantially T shape, and includes through holes 50a, 50a formed concentrically with the through holes 52a, 52a of the support piece 51 (only the near side is shown in FIG. 5). It has bearings 57, 57 mounted concentrically with the through holes 50a, 50a. Further, the slide plate 50 has first and second through holes 50b, 50c formed at the lower end thereof, and has a bearing portion 58 attached so as to be concentric with the first through hole 50b.

Insert the connecting rods 46, 46 into the through holes 52a, 52a, the through holes 50a, 50a and the bearings 57, 57, and compress between the rear flanges 48, 48 of the connecting rods 46, 46 and the bearings 57, 57. The springs (first biasing means) 59, 59 are arranged.

The holding member 32 is slidably supported on the connecting rods 46, 46 by screwing the tip screw portions 47, 47 of the connecting rods 46, 46 into the screw holes 45, 45 of the connecting portions 44, 44. . The holding member 32 is urged in the direction of arrow A by a compression spring 59.

The slide rod 60 is slidably attached to the first through hole 50b and the bearing portion 58. The tip 60a of the slide rod 60 is attached to the plate 62. The end contact member 34 is fixed to the plate 62 by bolts 63, 63.

As shown in FIG. 5, the cylinder unit 35 is slid so as to be concentric with the second through hole 50c. It is attached to the id plate 50 by bolts 61, 61. The piston port 36 of the cylinder unit 35 passes through the second through hole 50c. The tip 36a of the piston rod 36 is attached to the plate 62.

The liquid application member 33 contacts the outer peripheral portion 12 of the glass plate 10. The end face contact member 34 contacts the end face 13 of the glass plate 10. The holding member 32 supports both members such that the longitudinal direction of the liquid application member 33 and the longitudinal direction of the end face contact member 34 are orthogonal to each other. The holding member 32 has a cylinder unit 35 for changing the position of the end face contact member 34.

The application width W of the liquid application member 33 is arbitrarily changed by changing the position of the end surface contact member 34 in the direction of arrow B shown in FIG.

As described above, since the coating liquid W for the glass plate primer liquid coating device 20 is configured so that the coating width W can be arbitrarily changed by the cylinder unit 35, the movement amount of the piston rod 36 of the cylinder unit 35 can be adjusted. Thus, the coating width W can be arbitrarily changed. Therefore, as described in the related art, the application width is not limited to only two types.

The cylinder unit 35 for adjusting the coating width W is, for example, an electric cylinder for controlling the position by driving a screw (not shown) by a stepping motor. However, other means such as a ball screw may be used. In short, it is only necessary that the coating width W can be arbitrarily adjusted.

As described above, in the upper coating mechanism 25, the connecting rods 46, 46 are attached to the swing member 30 via the shaft 42 and the holding plate 43, and the holding members 32 are slid onto the connecting rods 46, 46. The plate 50 is slidably mounted, and compression springs 59, 59 are provided between the rear end flange portions 48, 48 of the connecting rods 46, 46 and the bearing portions 57, 57. By the compression springs 59, 59, the liquid application member 33 and the end surface contact member 34 are movably supported so as to come into contact with and separate from the end surface 13 of the glass plate 10, and the end surface 13 of the glass plate 10 Pressed to. Therefore, even if the end surface 13 of the glass plate 10 is displaced due to, for example, a manufacturing error of the glass plate 10, the end surface contact member 34 can be suitably pressed against the end surface 13 of the glass plate 10. .

As described above, the swing member 30 is attached to the stand 22 so as to swing about the support shaft 28. The support member 37 is attached to the upper part 23 of the stand 22. The upper end 31 a of the tension spring 31, which is the second urging means, is hooked on a pin 39 provided at the tip 38 of the support member 37. The lower end 31b of the tension spring 31 is provided at the rear end 30a of the swing member 30. Hung on pin 41. That is, the bow I tension spring 31 is interposed between the swing member 30 and the support member 37, and constantly urges the swing member 30 clockwise around the support shaft. By the tension spring 31, the liquid application member 33 and the end surface contact member 34 are vertically movably supported with respect to the outer peripheral portion 12 of the glass plate 10, and the liquid application member 33 is attached to the glass plate 10. It is pressed against the outer peripheral part 12.

And, for example, even when the outer peripheral portion 12 of the glass plate 10 is shifted upward or downward due to a manufacturing error of the glass plate 10, the swing member 30 swings clockwise or counterclockwise. Thereby, the liquid application member 33 is satisfactorily pressed against the outer peripheral portion 12 of the glass plate 10.

The amount of clockwise rotation of the swing member 30 is regulated by the first stopper bolt 64, and the amount of counterclockwise rotation is regulated by the second stop bolt 65.

As shown in FIG. 6, the liquid application member 33 is fixed to the tip end 54 of the support piece 51 on the upper surface 66 thereof with bolts 56, 56. The width of the lower surface 67 of the liquid application member is formed smaller than the width of the upper surface 66. An opening 68 is formed in the lower surface 67. The liquid applying member 33 has a storage portion 69 communicating with the opening 68. The storage section 69 stores a liquid suction member 70 such as felt. The bottom surface 71 of the liquid suction member 70 slightly protrudes from the lower surface 67. A first liquid supply hose 72 is connected to the upper end side of the liquid suction member 70, and a second liquid supply hose 73 is connected to the lower end side.

The primer liquid supplied from the first and second liquid supply hoses 72, 73 permeates the liquid suction member 70.

The end surface contact member 34 is a substantially rectangular parallelepiped block, and is fixed to the plate 62 with three bolts 63. The end face contact member 34 has a ridge 76 formed on a front face 75 thereof. The end surface 13 of the glass plate 10 abuts on the ridge 76. By forming the surface of the ridge 76 in an arc shape, the end face 13 of the glass plate 10 shown in FIG. 5 is smoothly moved.

By bringing the end surface 13 of the glass plate 10 into contact with the ridge 76, the bottom surface 71 of the liquid suction member 70 with respect to the outer peripheral portion 12 of the glass plate 10 is positioned. By moving the glass plate 10, a primer liquid having a predetermined width is applied to the outer peripheral portion 12 of the glass plate 10.

Returning to FIG. 3, the lower coating mechanism 26 applies the primer liquid to the end surface 13 and the inner peripheral portion 15 of the glass plate 10. The lower coating mechanism 26 applies the primer solution to the end face 13 of the glass plate 10. The configuration is the same as that of the upper coating mechanism 25, except that the upper coating mechanism 25 is configured to apply the liquid. Therefore, in the lower coating mechanism 26, the same components as those in the upper coating mechanism 25 are denoted by the same reference numerals, and description thereof will be omitted.

In order to apply the primer liquid to the end face 13 of the glass plate 10, a liquid suction member (not shown) is provided at the end face contact member 77, and a liquid supply hose 78 is connected to the liquid suction member. The primer liquid is supplied from the liquid supply hose 78, and the primer liquid is applied to the end face 13 of the glass plate 10 by infiltrating the liquid suction member with the primer liquid.

Next, the operation of the primer liquid applying apparatus for a glass plate according to the present embodiment will be described with reference to FIGS.

First, as shown in FIG. 3, the glass plate 10 is held by the suction pad 19 of the robot 18. Then, as shown in FIG. 7, the end surface 13 of the glass plate 10 is brought into contact with the ridge 76 of the end surface contact member 34, and the outer peripheral portion 12 of the glass plate 10 is brought into contact with the liquid application member 33.

In this state, by operating the robot 18 shown in FIG. 3, the glass plate 10 is moved while the glass plate 10 is in contact with the ridges 76 and the liquid application member 33 is in contact. The outer peripheral portion 12 of the glass plate 10 is coated with the reprimer liquid by the liquid suction member of the liquid coating member 33.

Here, during the application of the primer solution, if the outer peripheral portion 12 of the glass plate 10 is shifted upward due to a manufacturing error of the glass plate 10, the outer peripheral portion 12 of the glass plate 10 is moved upward. A force acts to lift the liquid application member 33 upward as shown by the arrow.

In FIG. 8, the upward lifting force of the outer peripheral portion 12 of the glass plate 10 is applied to the swing member 30 from the liquid application member 33 via the support piece 51, the support plate 43, the slide plate 50, and the shaft 42. It reaches the front end 30b. Therefore, the swing member 30 swings counterclockwise around the support shaft 28 against the urging force of the extension spring 31. By this swing, the liquid application member 33 follows the outer peripheral portion 12 of the glass plate 10. Therefore, it is possible to keep the liquid coating member 33 properly pressed against the outer peripheral portion 12 of the glass plate 10 and to apply the primer liquid to the proper coating surface without fail.

In FIG. 9, when the outer peripheral portion 12 of the glass plate 10 shifts downward due to a manufacturing error of the glass plate 10, the outer peripheral portion 12 of the glass plate 10 descends as indicated by the arrow. I do. Therefore, the outer peripheral portion 12 of the glass plate 10 tends to separate from the liquid application member 33.

In FIG. 10, the outer peripheral portion 12 of the glass plate 10 tries to separate from the liquid application member 33. This reduces the holding force of the liquid application member 33 by the outer peripheral portion 12 of the glass plate 10. As the force for holding the front end 30b of the swing member 30 decreases, the swing member 30 swings clockwise about the support shaft 28 by the urging force of the tension spring 31. By this swing, the liquid application member 33 follows the outer peripheral portion 12 of the glass plate 10. Therefore, the liquid application member 33 can be satisfactorily pressed against the outer peripheral portion 12 of the glass plate 10 so that the primer liquid can be surely applied to the regular application surface.

In FIG. 11, the glass plate 10 is brought into contact with the ridge 76 of the end face contact member 34 and the glass plate 10 is moved while being applied with the liquid application member 33, so that the outer peripheral portion 1 of the glass plate 10 is moved. The primer liquid is applied to 2 by the liquid suction member of the liquid application member 33. At this time, the liquid application member 33 is located at P1.

When the end surface 13 of the glass plate 10 projects toward the stand 22 due to a manufacturing error of the glass plate 10, the end surface 13 of the glass plate 10 points to the ridge 76 of the end surface contact member 34 by an arrow. It works like pressing.

The pressing force applied to the ridge 76 of the end face contact member 34 is transmitted from the plate 62, the cylinder unit 35, and the slide plate 50 to the compression spring 59. The slide plate 50 moves in the direction indicated by the arrow by staking the urging force of the compression spring 59.

In FIG. 12, when the slide plate 50 moves as indicated by the arrow against the urging force of the compression spring 59, the ridge 76 of the end face contact member 34 follows the end face 13 of the glass plate 10. That is, the end face contact member 34 moves in a direction away from the end face 13 of the glass plate 10.

At this time, the liquid application member 33 also follows the end surface 13 of the glass plate 10 integrally with the end surface contact member 34 and moves to a position P2 in a direction away from the end surface 13 of the glass plate 10. Therefore, the liquid application member 33 keeps a state of being pressed well against the outer peripheral portion 12 of the glass plate 10 and applies the primer liquid to the regular application surface of the glass plate 10 reliably.

If the end surface 13 of the glass plate 10 is displaced away from the stand 22 due to a manufacturing error of the glass plate 10, the end surface 13 of the glass plate 10 may be separated from the ridge 76 of the end surface contact member 34. And However, the ridge 76 of the end face contact member 34 moves following the end face 13 of the glass plate 10 by the urging force of the compression spring 59. At this time, the liquid application member 33 follows the end surface 13 of the glass plate 10 together with the end surface contact member 34. Therefore, the liquid application member 33 maintains a state in which it is satisfactorily pressed against the outer peripheral portion 12 of the glass plate 10. In FIG. 13, the glass plate 10 is in contact with the ridge 76 of the end surface contact member 34, and the liquid coating member 33 is in contact with the glass plate 10 while the glass plate 10 is moved, whereby the glass plate is moved. The primer liquid is applied to the glass plate 10 with the liquid suction member of the liquid application member 33 on the outer peripheral portion 12 of the substrate 10. At this time, by projecting the piston rod 36 of the cylinder unit 35 to the maximum, for example, the ridge 76 of the end surface contact member 34 approaches the tip 70a of the liquid suction member 70. Thus, the application width W of the outer peripheral portion 12 of the glass plate 10 is minimized by the maximum protrusion of the piston 36.

For example, there is a case where, after the application width W of one side of the outer peripheral portion 12 of the glass plate 10 is reduced, the application width W of the other side is desired to be increased. In such a case, by moving the piston rod 36 of the cylinder unit 35 as shown by the arrow, the end face contact member 34 together with the plate 62 is moved away from the tip 70a of the liquid suction member 70 as shown by the arrow.

In FIG. 14, the distance from the ridge 76 of the end surface contact member 34 to the distal end 70a of the liquid suction member 70 is increased by moving the end surface contact member 34 away from the tip 70a of the liquid suction member 70. (4) The coating width W of the outer peripheral portion 12 of the glass plate 10 is increased.

Thus, by changing the position of the end face contact member 34 with the cylinder unit 35, the application width W of the liquid application member 33 can be changed.

In some cases, it is desirable to change the coating width within one side of the glass plate 10, for example, within the range of one side such as the left side. << The glass plate primer liquid coating device 20 of the present embodiment can be used to cope with such a case. can do.

As described above, in the present embodiment, during the application of one glass plate 10, the application width W may be arbitrarily changed for each side of the glass plate 10, or a range of one side such as the left side may be used. Described in the example where the coating width is desired to be changed in the case of << The use of the primer liquid coating device 20 for glass plates allows the application of the primer liquid to various glass plates 10 having different coating widths W. Also

As described above, if various glass plates 10 having different coating widths W can be handled by one glass plate primer liquid coating device 20, the equipment can be simplified.

In the above-described embodiment, an example in which the tension spring 31 is used as a means for swinging the swing member 30 has been described. However, the present invention is not limited to this, and a compression spring may be used.

Further, in order to press the ridge 76 of the end face contact member 34 against the end face 13 of the glass plate 10, Although an example using a compression spring has been described, the invention is not limited to this, and a tension spring may be used. Industrial applicability

By changing the position of the end surface contact member with the cylinder unit, the width of application of the liquid application member to the glass plate can be arbitrarily changed. Therefore, even during the application of one glass plate, it is possible to arbitrarily change the application width of each side of the glass plate and the application width within one side, and place a resin molding around the glass plate. Provided, for example, useful in the manufacture of automotive glazing.
