Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an automatic sticking method in which a thin seal that has been punched is sucked and held by a sucking means, is opposed to a sticking surface of an object to be stuck, and is mechanically stuck by pressing through an adhesive, and It relates to the device.
[0002]
[Prior art]
Normally, the stamped and stamped seals are aligned and bundled in a separate process, and the operator uses the required affixing tool to attach it to the affixing surface of the object to be adhered in a manual assembly process. Since it is necessary to mechanically realize this on the line to improve productivity, the already stamped seal is sucked and held by the suction means and is made to face the pasting surface of the object to be adhered. Thus, an automatic sticking method and apparatus for a seal that is mechanically stuck by pressing has been proposed.
[0003]
[Problems to be solved by the invention]
However, the problem here is that the seal is thin and easily wrinkles before or during sticking. In particular, when the seal has an elongated shape, it is difficult to stick it cleanly simply by mechanically pressing the seal against the sticking surface of the adherend. Therefore, it may be possible to mechanically perform the work of scoring the sealing surface to the above-mentioned attaching surface, such as manual work, but this complicates the device and sucks the seal until just before sticking. This impedes the work area of the suction finger unit to be held or the work area of the pressing means of the seal during sticking, making it difficult to realize mechanization.
[0004]
The present invention has been made on the basis of the above circumstances, and the object of the present invention is not to impair the work area such as sticking and holding of the seal until immediately before sticking by the sucking means, and sticking of the seal by the pressing means. Another object of the present invention is to provide an automatic sticking method and apparatus for a thin pressure seal which is devised so as to allow clean sticking without causing wrinkles.

[0031]
Next, the sticking operation of the thin sticker automatic sticking apparatus having such a configuration will be specifically described. On the other hand, the adherend W placed on the transport tray 901 is transported by the transport means (transport conveyor) 4 and stopped at the sticking position P by a stopper or the like. Then, the positioning means 9 drives the air cylinders 908 and 909 to advance the support pins 904 and 905 so as to fit in the reference holes on the side surfaces of the adherend W. Thus, the positioning of the adherend W at the sticking position P is completed.
[0032]
In the elastic deformation control means 5, initially, the air cylinder 513 is retracted, and the pin 515 is lowered along the inclined surface by the spring 516, and is disengaged from the lock groove 517. Therefore, the deformation operation shafts 508 a to 508 c are removed. Is in a free state and is kept in a forward state by the action of the air cylinder 506.
[0033]
In this state, when the air cylinder 501 ascends the lifting platform 503, the engaging claws 510a to 510c pass through the opening of the transport tray 901 and go under the adherend W. Next, when the air cylinder 506 is retracted, the spring 507 is activated, the deformation operation shafts 508a to 508c are retracted, and the engaging claws 510a to 510c are engaged with the engaging portion e. In this state, the air cylinders 504a to 504c are operated until the respective forward position detection sensors 518 detect the predetermined positions, and the engaging claws 510a to 510c are moved backward by the required amounts x2, x1, and x2, respectively. The sticking surface s of the adherend W is deformed into a concave shape.
[0034]
On the other hand, in the process of supplying the thin sealing material A to the press means 2 via the seal supply line L, the dust on the surface is removed by the dust collector 802, and at the same time, the function of the electrode 803 is also free of static electricity. Removed. In addition, the thin seal material A is sandwiched by the finger jaws 812 and 813 and sent to the press means 2 side via the cable bear 811 at the synchronized timing under the control of the entire system. During this time, the thin sealing material A is fed between the upper die member 202 and the lower die member 203 for the required length to be pressed in a tension state in which tension is applied by the action of the feed rollers 105 and 106. .
[0035]
At this stage, the clamper 6 works to temporarily stop the thin seal material A and release the finger jaws 812 and 813. Then, the cable bear 811 returns to the initial position. The lower mold member 203 is raised at the synchronized timing, and the thin seal material A is sandwiched between the lower mold member 202 and the punch 208, and the thin seal a having a required shape is punched by the punch 208. The seal a is sucked to the suction pad 303 by the action of the suction / conveyance means 3. The waste material A ′ is discharged to a required place by the feed rollers 105 and 106 as described above.
[0036]
Then, the suction / conveyance means 3 operates the air cylinder 305 to draw out the thin seal “a” on the suction pad 303 from the press means 2 and transfers it to the sticking position P by the transfer control robot 302. Thereafter, the rolling means 306 is actuated so that the suction pad 303 faces the pasting surface s of the above-described positioning object W, and again, the suction pad 303 is brought to the pasting surface s by the air cylinder 305. Aim and press. Thereby, the thin seal a is stuck at least at both ends in the longitudinal direction. Thereafter, the suction force to the vacuum suction port 304 is released by the control means.
[0037]
After sticking, the elastic deformation means 5 is operated in the reverse order to release the engagement between the engagement claws 510a to 510c and the engagement portion e, and finally the elevator platform 503 is moved downward, Return each component to its original state. Since the elastic deformation means 5 releases the elastic deformation of the adherend W, the bonding surface s returns from the concave shape to the flat state, so that the thin seal a is stretched in the longitudinal direction by this return operation. The entire surface is brought into close contact with the pasting surface s without any wrinkles.
[0038]
Then, the suction / conveyance means 3 retracts the suction pad 303 from the attaching surface s by the action of the air cylinder 305a, and first returns the seal suction finger unit 301 to the transport start end by the action of the transfer control robot 302.
[0039]
The system is controlled by such a series of operation orders, whereby the automatic sticking apparatus is repeatedly operated.
[0040]
【The invention's effect】
The present invention has been described in detail above, and a thin seal that has been punched and punched is held by suction with an adsorbing means, and is opposed to the affixing surface of an object to be adhered, and mechanically pressed by an adhesive. In the automatic sticking method for sticking, prior to sticking, the sticking surface is elastically deformed so that the sticking surface is bent into a concave shape by the movement of the engaging claw, and in that state, a thin seal is attached. Since the elastic deformation is released after pressing and sticking to the above-mentioned sticking surface, even if a simple automatic sticking device is adopted, even if it is a thin seal, it is fast and accurate without causing wrinkles. The productivity can be improved significantly.
