Description

  The present invention relates to an automatic sticking device for sticking a foam seal material to a sticking surface of an automobile body or a windshield.

  Conventionally, a striped foam sealing material made of a rubber-based foam layer has been attached to a steel plate or a windshield constituting an automobile body for the purpose of soundproofing, waterproofing, vibration proofing, dustproofing, and the like. Affixing surfaces of steel plates or the like that constitute the body of an automobile are often complicated curved surfaces that are bent in a three-dimensional direction.

  This type of foam sealing material has been affixed manually by workers. The release paper is bonded to the back surface of the foam sealant through an adhesive layer formed on the back surface, and the operator peels off the release paper, along the pattern paper called gabari, such as a steel plate. The foaming sealing material was affixed on the affixing surface through the said adhesion layer.

  Patent Document 1 has an adhesive layer on one side of a rubber-based foam layer having a continuous foam structure, and a reinforcing layer that can be cut by hand as needed, also serving as a release layer for the adhesive layer on the other side. There is described an airtight foamed sealing material comprising a wound body having a state in which the adhesive layer is bonded to the reinforcing layer.

  Further, Patent Document 2 discloses an automatic sticker pasting composed of a release paper transport mechanism for transporting a release paper having a seal, a hand having a seal suction mechanism at the tip of an air cylinder, and a moving mechanism for moving the hand. An attachment device is described.

= Configuration of connecting link 4 and connecting link deformation mechanism 30 =
FIG. 5 is a front view of the hand 5 and the connecting link 4. FIG. 6 is a top view showing a state of the connecting link deformation mechanism 30 when the connecting link 4 is in a straight line state. FIG. 7 is a top view showing a state of the connecting link deformation mechanism 30 when the connecting link 4 is in a curved state.

  The connecting link 4 is formed by connecting a plurality of link plates 4a to each other via connecting shafts 4b at both ends of each link plate 4a, and each link plate 4a is in the XY plane with the connecting shaft 4b as a rotation axis. It is configured to be rotatable. The plurality of hands 5 are respectively attached to the lower surface of each link plate 4a. Then, by rotating and deforming the connecting link 4 by the connecting link deforming mechanism 30, the plurality of hands 5 are in a linear state in the XY plane in conjunction with the connecting link 4 while holding the foam seal material 2. Or a curved state.

  The connecting link deformation mechanism 30 includes an air cylinder 15, a pressing member 16 attached to the tip of the air cylinder 15, a straight bar 17 extending in the X direction and having a straight end surface, and an end surface extending in the X direction. A curved bar 18 that is curved is included.

  Before the release paper 7 adhered to the foam sealing material 2 by the slide pin 9 is peeled off, the connecting link 4 is in a straight line in the XY plane. At this time, as shown in FIG. 6, the pressing member 16 is driven in the direction of the arrow by the air cylinder 15, and the side surface of the connecting link 4 is pressed against the straight bar 17 by the pressing member 16. It is in a straight line state in the Y plane.

  And after all the release paper 7 adhere | attached on the foaming sealing material 2 with the slide pin 9 peeled, the connection link 4 will be in a curved state in XY plane. Since all of the release paper 7 is peeled off, the foamed sealing material 2 can be bent freely. At this time, as shown in FIG. 7, the pressing member 16 is reversely driven by the air cylinder 15 in the direction of the arrow, and the side surface of the connecting link 4 is pressed against the curved bar 18, thereby bringing the connecting link 4 into the XY plane.

  In this way, the height of the plurality of hands 5 in the Z direction is adjusted, and the shape of the plurality of hands 5 in the XY plane is deformed by the connecting link 4 to thereby change the shape of the foam seal material 2 to the workpiece. It can be matched to the curved surface shape of the W attachment surface.

  The connecting link deformation mechanism 30 can also be provided with an air cylinder 20 and a connecting plate 21 as a deformation mechanism for bending the link plate 4a at the end of the connecting link 4 in the XY plane. The connecting plate 21 connects the front end of the air cylinder 20 and the link plate 4a at the end of the connecting link 4 so as to be rotatable in the XY plane at the connecting portion.

  That is, as shown in FIG. 6, when the air cylinder 20 is driven in the direction of the arrow, the connecting link 4 is linear as a whole. However, as shown in FIG. 7, when the air cylinder 20 is reversely driven in the direction of the arrow. The link plate 4a at the end of the connection link 4 rotates, for example, 90 ° from the straight state.

== Paste Operation of Automatic Pasting Apparatus 1 ==
The pasting operation of the automatic pasting apparatus 1 is summarized as follows. In this case, each component of the automatic pasting apparatus 1 and its operation are controlled by a control device (not shown). Further, it is assumed that the workpiece W is transported to the foam sealing material pasting position in the automatic pasting apparatus 1 by the workpiece moving table 12.

  The operator stands in front of the foam seal material holder 3 stationary at the set position, and sets the foam seal material 2 along the upper surface of the holding board 3a so that the release paper 7 is in contact with the upper surface of the holding board 3a. To do. Subsequent operations are automatically executed by the automatic pasting apparatus 1.

  The foam sealing material holder 3 on which the foam sealing material 2 is set moves to a position immediately below the plurality of hands 5 and further moves up to the height of the pair of claws 5a and 5b of the plurality of hands 5. The plurality of hands 5 grip the side surface of the foam seal material 2 set in the foam seal material holder 3. When the foam seal material 5 is gripped by the plurality of hands 5, the foam seal material holder 3 returns to the set position of the foam seal material 2.

  Next, the plurality of hands 5 move downward in the Z direction to the release work position of the release paper 7 while holding the foam seal material 2. Then, the release paper 7 is peeled off by the chuck 6 and the slide pin 9. Thereafter, the connecting link 4 is deformed by the connecting link deformation mechanism 30 to bend the foamed sealing material 2 gripped by the plurality of hands 5 to match the curved surface shape of the attachment surface of the workpiece W.

  Thereafter, the plurality of hands 5 move to the foam seal material application position while holding the foam seal material 2, and are separated by the slide pins 9 onto the application surface of the workpiece W waiting at the foam seal material application position. The foam sealing material 2 after the pattern paper 7 has been completely peeled off is attached. The plurality of hands 5 that have completed the application of the foam sealing material 2 release the foam sealing material 2 and return to the original position.

  Next, the workpiece moving table 12 on which the workpiece W to which the foam seal material 2 is attached is delivered to the workpiece conveyance table 11. The workpiece transfer table 11 that has received the workpiece W from the workpiece moving table 12 transfers the workpiece W to the foam seal material fixing jig 13. The pressing tool 14 of the foam seal material fixing jig 13 presses the upper surface of the foam seal material 2 affixed to the work W, thereby firmly fixing the foam seal material 2 to the surface of the work W.
