Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible substrate feeder, and more particularly to a flexible substrate feeder which separates and supplies flexible substrates one by one.

[0002]

2. Description of the Related Art For example, in an optical pickup portion of a compact disc player, a flexible substrate is used as a wiring means for supplying a current to a servo coil or the like. In the case of incorporating such a flexible substrate into an optical pickup, the flexible substrates are separated and assembled one by one.

A very small type flexible substrate such as used for an optical pickup of a compact disc player has been supplied by being stuck on a carrier film in an aligned state. At the time of assembling work, an operator separates the pieces one by one with tweezers or the like and assembles them into a predetermined position of the frame of the pickup.

[0004]

In the case of automatically assembling the optical pickup of a compact disc player, it is necessary to provide a device for separating the above flexible substrates one by one and automatically supplying them. However, the sheet-shaped carrier film used for manual assembly cannot provide continuous feeding for a long time. Also, if the flexible substrate is thin and extremely small, the area for adsorption is reduced. For this reason, when peeling the flexible substrate from the carrier film, the flexible substrate loses the force of the adhesive and cannot be separated.

The present invention has been made in view of the above problems, and in particular, it is possible to surely separate the flexible substrates supplied in the state of being adhered to the carrier film one by one and reliably supply them. It is an object of the present invention to provide a flexible substrate supply device as described above.

[0006]

According to a first aspect of the present invention, there is provided a flexible substrate supply device for separately supplying flexible substrates one by one, and a carrier film to which the flexible substrates are attached in an aligned state, and a tip side of the carrier film. A separation table that has an acute angle and separates the flexible substrate that is attached by bending the carrier film at the acute angle portion, and a flexible substrate that is disposed in front of the acute-angled tip of the separation table and is separated. The present invention relates to a flexible substrate supply device that includes a pedestal for receiving and a suction head that suction-holds the flexible substrate received on the pedestal.

A second invention is the same as the first invention,
The present invention relates to a flexible substrate supply device, wherein an acute-angled tip portion of the separation table is elastically biased toward the cradle side by a spring.

A third aspect of the invention is the same as the first aspect of the invention.
The present invention relates to a flexible substrate supply device in which a silicon layer is formed on the surface of the pedestal.

[0009]

According to the first aspect of the invention, the flexible substrate is neatly supplied in the state of being attached by the carrier film. Then, when the carrier film is guided onto the separation table and is bent at an acute angle portion on the tip side,
At this time, the flexible substrate is separated from the carrier film. The separated carrier film is received by a pedestal arranged in front of the sharp tip of the separation table. Then, the flexible substrate on the pedestal is sucked and held by the suction head and supplied to a predetermined position.

According to the second aspect of the invention, since the acute-angled tip portion of the separation table is biased toward the cradle side by the spring, a gap is formed between the cradle and the tip portion of the separation table. It can be made extremely small, which improves the performance of separating the flexible substrate by the separation table.

According to the third invention, since the silicon layer is formed on the surface of the pedestal, when the flexible substrate attached to the carrier film is separated from the carrier film and supplied to the pedestal. , It becomes difficult to stick to the surface of the cradle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the overall structure of a flexible substrate supply apparatus according to an embodiment of the present invention, in which a carrier film 10 having a flexible substrate 20 attached in an orderly state is an outer periphery of a roll 11. It is designed to be wound on the side. The carrier film 10 pulled out from the roll 11 is separated by a guide roll 12 into a separation table 13
It is supposed to be supplied on top. A pedestal 15 supported by a frame 14 is arranged on the front side of the separation table 13. Further, a suction head 16 is provided above the pedestal 15 so as to be movable up and down and movable.

The flexible substrate 20 is supplied by the carrier film 10 and the separation table 1
The pedestal 1
5 are supplied so that they are sequentially placed on the upper surface of the container 5. Then, after this, the suction head 16 sucks and holds it, and the work 21 is assembled. The work 21 is carried by a suitable carrying means such as a pallet 22.

Pins 25 and 26 are planted on the side surfaces of the separation table 13 and the pedestal 15, respectively, and a tension coil spring 27 is stretched between the pair of pins 25 and 26. Has become. Further, four guide rolls 28 are provided below the flexible substrate supply device.
29, 30 and 31 are provided to guide the carrier film 10 from which the flexible substrate 20 is separated downward.

FIG. 2 shows a carrier film 10 to which a flexible substrate 20 separated and supplied by such an apparatus is attached. FIG. 3 shows a carrier film 10 to which another flexible substrate 20 is attached and supplied.

As shown in FIG. 4, these two types of flexible substrates 20 are assembled on a frame 35 of an optical pickup of a compact disc player. That is, the flexible substrate 20 shown in FIG. 2 is attached and attached to the front end portion of the frame 35. On the other hand, the flexible substrate 20 shown in FIG. 3 is attached to the rear portion of the frame 35. In addition, the concave portion 3 of the pickup frame 35
A plastic lens 37 is incorporated in the reference numeral 6.

As described above, in the flexible substrate supply apparatus according to the present embodiment, the carrier film 10 is roll 1 at a constant amount.
In the process of delivering the carrier film 10 from the carrier film 10 and transporting the carrier film 10, the flexible substrate 20 which is orderly attached on the carrier film 10 is automatically separated.
It is designed to be transferred onto the pedestal 15 located on the tip end side of 3.

Then, the suction head 16 descends onto the pedestal 15 to suck the flexible substrate 20 in vacuum. The suction head 16 ascends in a state in which the flexible substrate 20 is sucked, and then moves in the lateral direction so that the flexible substrate 20 is attached to the work 21 on the pallet 22 and assembled. After that, the suction head 16 returns to the top of the pedestal 15 and repeats the above operation.

The sheet-like carrier film used for manual assembly makes continuous automatic supply for a long time difficult. Therefore, in this embodiment, the long carrier film 10 is used as described above, and is wound around the roll 11 and fed out. As shown in FIG. 2 or FIG. 3, the flexible substrate 20 is supplied in such a state that it is orderly adhered onto the carrier film 10.

Flexible substrate 2 to which an adhesive is attached
It is very difficult to separate 0 from the carrier film 10 by vacuum adsorption. So carrier film 1
In the process of transporting 0, the flexible film 20 is separated by bending the carrier film 10 at an acute-angled portion on the tip side of the separation table 13. Moreover, in front of the separation table 13, a pedestal 15 having a silicon layer 18 adhered on the surface is provided.
The flexible substrate 20 is once placed on the substrate 5. Then, after this, the cradle 1 is attached by the suction head 16.
By vacuum suctioning the flexible substrate 20 from 5, the flexible substrate 20 can be reliably and smoothly separated and supplied. The silicon layer 18 may be omitted if the adhesive strength of the adhesive layer that adheres the flexible substrate 20 is weak.

According to such a flexible substrate supply device, the carrier film 10 wound around the roll 11 is wound.
By increasing the length of, the continuous supply for a long time becomes possible. Further, since the separated flexible substrate is sucked and moved by the suction head 16, the time for attaching the separated flexible substrate can be shortened. Further, the flexible substrate 20 can be automatically attached, and labor can be saved. Furthermore, since the flexible substrate can be automatically assembled, the quality of the optical pickup of a compact disc player can be stabilized.

[0022]

According to the first aspect of the present invention, a flexible substrate is supplied in a state of being aligned and attached by a carrier film,
The flexible board attached is separated by bending the carrier film at an acute angle portion on the tip side of the separation table, and the separated flexible board is temporarily received on a cradle arranged on the tip side of the separation table. In this way, after this, the suction head is used to suction and hold.

Therefore, it becomes possible to supply the flexible substrate in a state where it is adhered to the carrier film in an orderly manner, and to separate such flexible substrates one by one and supply them to a predetermined position, thereby achieving automation of the supply of the flexible substrate. Will be done.

A second aspect of the invention is such that an acute-angled tip portion of the separation table is elastically biased toward the cradle side by a spring. Therefore, there is no gap between the tip of the separation table and the pedestal, and the flexible substrate can be reliably separated from the carrier film at the tip of the separation table, and the separation performance is improved.

The third invention is such that a silicon layer is formed on the surface of the pedestal. Therefore, the flexible substrate separated at the acute-angled tip of the separation table does not stick to the surface of the cradle to prevent suction by the suction head, so that the flexible substrate can be smoothly separated and supplied.
