Abstract

PURPOSE: To automatically and effectively stick an adhesive tape on a thin plate member by preparing the adhesive tape cut to required length in an adsorbed state, and quickly sticking it on the thin plate member after positioning it. CONSTITUTION: A thin plate member 1 carried through a course shown by (a) from a previous process is transfered to a conveyor 2 and carried until striking against a stopper 3. After a sensor 4 confirms striking, a positioning unit section X is lowered in a direction of (c) by a cylinder 5. A positioning pin 6 is provided in the positioning unit section X to guide the guide hole 7 of the thin plate member 1. After confirming that the thin plate member 1 has been positioned by the positioning unit X, an adsorption section 9 which adsorbingly holds an adhesive tape 11 cut to a fixed length with an adsorbed face set upward is raised in a direction shown by (d) by cylinder 10 to put the thin plate member 1 between a pressing plate 8 and itself, and the adsorption made by the adsorption section 9 is then released to stick the adhesive tape 11 on the thin plate member 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic tape applying apparatus for automatically applying an adhesive tape to a thin plate member, and more particularly to an apparatus for applying an adhesive tape cut into a certain length.

[0002]

2. Description of the Related Art A conventional tape sticking apparatus moves an XY table while pressing an adhesive tape on a thin plate member by a sticking roller with a thin plate member fixed on the XY table, and loading the adhesive tape. It was peeled from the reel, attached to a thin plate member, attached to a predetermined length, and then cut.

[0003]

In the prior art, the operation of cutting the adhesive while adhering the adhesive tape to the thin plate member was not efficient when the number of adhesive tapes to be adhered was small. At present, there is a strong demand for improvement in work efficiency due to labor saving in the work of applying an adhesive tape.

An object of the present invention is to efficiently and automatically attach an adhesive tape to a thin plate member when the attaching length and attaching location of the adhesive tape are limited.

[0005]

In order to achieve the above object, the present invention cuts into a required length with a conveyor for conveying a thin plate member, a positioning unit for positioning the conveyed thin plate member at a predetermined place. A tape sticking unit is provided which can stand by in a state where the adhesive tape is adsorbed and can quickly carry out the sticking operation after the positioning of the thin plate member is completed.

[0006]

The conveyor, which is the above means, can be adjusted to a width that allows the thin plate member to be smoothly conveyed. For example, by providing a stopper on the conveying line, the thin plate member conveyed from the previous step is always stopped at a fixed position. be able to. Further, after completion of the series of adhesive tape attaching operations, the thin plate member can be conveyed to the subsequent process by releasing the stopper.

The positioning unit is provided with a positioning pin, descends from above the thin plate member positioned by the stopper on the conveyor, and guides the guide hole of the thin plate member, thereby enabling reliable positioning. Further, by providing a press plate that comes into close contact with the thin plate member so that there is almost no gap between the thin plate member and the position where the entire positioning unit reaches the bottom dead center, it is possible to correct the warp of the thin plate member.

The tape sticking unit waits with the adhesive tape cut to a predetermined length, rises from below the positioned thin plate member, and completes a series of adhesive tape sticking operations with a suction section for sticking the adhesive tape. After that, it has a plurality of suction parts of the suction part that peels while pulling in the state that the adhesive tape set in the tape loading part is sucked, and these suction parts reciprocate with each other to efficiently attach the adhesive tape. It will be possible.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a detailed view of a combination of a conveyor section, a positioning unit section, and a tape sticking unit section according to the embodiment of the present invention in which the number of sticking adhesive tapes is one. The thin plate member 1 which has been conveyed from the previous step through the path a is transferred to the conveyor 2 and conveyed until it abuts on the stopper 3. After confirming the contact with the sensor 4, the positioning unit X is lowered by the cylinder 5 in the c direction. A positioning pin 6 is provided in the positioning unit X, and a guide hole 7 of the thin plate member 1 is provided.
To guide. The warp of the thin plate member 1 can be corrected by adjusting the press plate 8 to a position where the press plate 8 is substantially in close contact with the thin plate member 1 in a state where the positioning unit X is lowered to the bottom dead center. Further, by minimizing the clearance between the positioning pin 6 and the guide hole 7, reliable and highly accurate positioning can be performed. After confirming that the thin plate member 1 has been positioned by the positioning unit X, the suction portion 9 that holds the adhesive tape 11 cut into a certain length with the adhesive surface facing upward ascends in the direction d by the cylinder 10. Then, the thin plate member 1 is sandwiched between the press plate 8 and the suction portion 9, and the suction of the suction portion 9 is released, so that the adhesive tape 11 can be attached to the thin plate member 1. As described above, after the completion of a series of pasting operations, the cylinder 10 lowers the suction portion 9 and the cylinder 5 raises the positioning unit portion X to restore the initial state. By releasing the stopper 3, the thin plate member 1 on the conveyor 2 is conveyed to the subsequent process through the route of b. From the conveyance of the thin plate member 1 to the subsequent process until the next thin plate member 1 is conveyed from the previous process and positioned at a fixed position on the conveyor 2, in the tape application unit Y, the suction tape 12 and the cylinder 13 form the adhesive tape 11. Is cut into a certain length, and an operation for standing by below the conveyor 2 is performed. FIG. 2 is a flow chart of the operation. (A) The suction portion 9 raised by the cylinder 10 descends after the adhesive tape 11 has been attached to the thin plate member 1, and returns to the initial state. (B) The entire cylinder 10 and the suction unit 9 further descend from the initial state in the e direction. (C) Cylinder 1
0, the suction unit 9 and the cylinder 13, and the suction unit 12 are f,
Move in g direction. At this time, the suction unit 12 sucks the adhesive tape 11 set in the adhesive tape loading unit 14 and moves while peeling it. (D) The cylinder 10 and the suction portion 9 rise in the h direction to suck the adhesive tape 11. (E) The cutter 18 is rotated by the motor 17 and ascends in the i direction to cut the adhesive tape 11. (F) The cutter 18 is
After cutting, it quickly descends in the j direction, and the adhesive tape loading unit 14
The adhesive tape 11 is wound up by rotating in the direction e. (g) The rotation of the adhesive tape loading unit 14 is stopped when the sensor 15 no longer detects the adhesive tape 11. With the above operation, the adhesive tape 11 cut into a certain length can be always kept in the same state.

According to this embodiment, by repeating this operation, the adhesive tape can be continuously and efficiently attached to the thin plate member.

[0011]

According to the present invention, the work of attaching the adhesive tape to the thin plate member can be continuously and efficiently performed automatically, so that the work time can be shortened and the labor can be saved. Further, the length of the sticking tape and the sticking position on the thin plate member can be accurately kept constant.
