A liquid crystal panel is generally manufactured by laminating glass plates, and a chip, which is a driver, is bonded onto electrodes formed at a narrow pitch on a side edge portion of the glass plates.

As the driver, a chip made of a film carrier or a flip chip is often used. In this case, it is necessary to accurately position and bond electrodes such as outer leads of chips and bumps of flip chips to electrodes of the display panel. Therefore, electrodes such as outer leads and bumps have been bonded to the electrodes of the display panel via an anisotropic conductive tape having adhesiveness (hereinafter referred to as "ACF").

Since ACF has adhesiveness and its surface is delicate, it is generally wound around a supply reel with a separator sandwiched between the ACF and the ACF.
While feeding the separator, it is cut into a predetermined length by a cutter and attached to an electrode of the display panel.

The technique of bonding a chip to a display panel by ACF is a relatively new technique which has been attracting attention in recent years, and although the technique is not well established at present, the conventional anisotropy is used. Conductive tape (ACF)

Further, by suctioning the upper surface of the separator 3 by vacuum, it is possible to impart a feeding resistance to the delicate ACF 2 having a sticky surface in a non-contact manner and prevent the ACF 2 from being damaged.

In FIG. 7, a pillar 41 is erected on the side of the block 38, and two pins 42 are erected on the upper surface thereof (see also FIG. 3). The pin 42 prevents the ACF 2 and the separator 3 from wobbling in the lateral direction. Pin 4
A plate body 43 is provided above 2. Two lower tongue pieces 44a and 44b are provided on the lower portion of the plate body 43. The tips of the ACF 2 and the separator 3 are sandwiched between the upper and lower tongue pieces 44a and 44b and positioned in the height direction. By positioning the tip of the ACF 2 in the height direction with the two tongue pieces (members) in this manner, the chuck of the tip of the ACF 2 by the chuck claw 82 of the pull-out means 80 can be reliably performed. A pin 45 projects from the upper portion of the plate body 43, and a spring 46 is stretched between the pin 45 and the side plate 9 of the cassette 10. The plate body 43 is urged to the right by the spring force of the spring 46. The plate body 43 is held by the guide portion 47 so as to be able to move forward and backward in the lateral direction N3, that is, the feeding direction of the ACF 2 and the separator 3.

Next, referring to FIGS. 8 and 9, the ACF2
The operation of pulling out the separator 3 will be described. Initially, as shown in FIG. 8A, the tips of the ACF 2 and the separator 3 are located between the tongue pieces 44a and 44b. The plate body 43 is in contact with the side plate 9 by the spring force of the spring 46. Next, as shown in FIG.
2 advances to the left, enters the cassette 10 from the lead-out portion 11, presses against the tongues 44a and 44b, and causes the plate body 43 to retract to the left against the spring force of the spring 46. Then, the tip portions of the ACF 2 and the separator 3 are tongue pieces 44a and 44b.
Projects slightly to the right from. Therefore, as shown in FIG. 9A, the chuck claw 82 is closed to hold the tip.
Next, as shown in FIG. 9B, the chuck claw 82 is retracted to the right, the ACF 2 and the separator 3 are pulled out from the lead-out portion 11 of the cassette 10, and the upper surface of the pulled-out separator 3 is moved to the head 90 (FIG. 1). Vacuum adsorption. At the same time, the plate body 43 slides to the right by the spring force of the spring 46 and contacts the side plate 9. After that, the cutter 94 moves up and down to cut the drawn ACF 2 and the separator 3 into a predetermined length, and the head 90 cuts the cut ACF 2
And the separator 3 are attached on the electrodes 7 of the display panel 5.
In this way, the ACF 2 and the separator 3 are connected to the cassette 10
When pulled out, the block 38 shown in FIG. 7 lightly vacuum-sucks the separator 3 to prevent the ACF 2 and the separator 3 from unnecessarily wandering when pulled out.

Next, referring to FIGS. 10 and 11, A
A delivery mechanism of the separator 4 separated from the CF2 will be described. The roller 33 is pivotally attached to a key-shaped lever 58. The right end of the lever 58 is fixed to the main plate 12 by a pin 59.
And is urged counterclockwise by a spring 60. Reference numeral 49 is a stopper that defines the counterclockwise rotation limit of the lever 58. A window 61 is opened in the lower part of the main plate 12, and a driving roller 77 and a push-up roller 69 (see also FIG. 2) enter the inside of the cassette 10 through the window 61. The separator 4 is the roller 3
3 and the drive roller 77. A block-shaped clamper 62 is provided at the tip of the lever 58, and a clamper 63 is provided inside the side plate 9 of the cassette 10. When the lever 58 is urged downward by the spring force of the spring 60, the tip end of the separator 4 is clamped by the clampers 62 and 63 and fixed so as not to wobble unnecessarily.

Push-up roller 69 on the body frame 1 side
Is driven by a driving means (not shown) such as a cylinder to move up and down. FIG. 11 shows a state in which the push-up roller 69 is raised. When the push-up roller 69 rises, the lever 58 is pushed by this and rotates clockwise, and the roller 33 is rotated.
The drive roller 77 holds the separator 4 therebetween. The clamper 62 also rises, and the clamped state of the tip of the separator 4 by the clampers 62 and 63 is released. Then, the motor 78 (FIG. 2) is driven to rotate the driving roller 77, whereby the separator 4 is fed to the left and is fed from the feeding portion 35 to the box 8.

Next, the fixing means of the separator 4 will be described. In FIG. 10, 64 is a block, and 65 is a rotor provided below the block 64. The rotor 65 is pivotally attached to a pin 66 and is elastically urged by a spring 67. 68 is a stopper for the rotor 65. At all times,
The rotor 65 is in the position shown by the solid line in FIG. In this state, there is a space between the block 64 and the rotor 65, and the separator 4 freely feeds this space. In the case where the cassette 10 is detached from the main body frame 1 and handled and transported, if the separator 4 sways and falls off the rollers 27 to 32, the separator 4 must be adjusted again to the rollers 27 to 32 later, which is troublesome. It will be Therefore, the rotor 65 is rotated clockwise about the pin 66, and the separator 65 is rotated by the rotor 65 and the block 64.
Are clamped and fixed (see the rotor 65 shown by a chain line in FIG. 10). When the cassette 10 is set in the main body frame 1 to operate the apparatus, the rotor 65 is rotated counterclockwise to release the fixed state of the separator 4.

If the separator 4 is sandwiched between the block 64 and the rotor 65 in this way, the separator 4 becomes the roller 2
It does not fall from 7-32. In this case, if the tip portion of the separator 4 is fixed by the clampers 62 and 63, the tip portion will not be lost, and if the cassette 10 is set on the main body frame 1, the apparatus can be operated immediately. become. In FIG. 10, the consideration point of the spring 67 of the rotor 65 is in the middle between the solid line position and the chain line position, and therefore, the rotor 65 selectively selects the solid line position and the chain line position with moderation. As shown in FIG. 7, a similar rotor 65 is also provided below the block 38, and this rotor 65 is rotated in the direction of the arrow so that the rotor 65 and the block 38 cause the ACF 2 and the separator 3. 4 is fixed, and the ACF 2 and the separators 3 and 4 are rollers 28 and 29 and the pin 3 for peeling during transportation.
If the cassette 10 is set in the main body frame 1, the device can be immediately operated if the cassette 10 is not dropped. That is, the blocks 38, 64 and the rotor 65 serve as fixing means for fixing the ACF 2 and the separators 3, 4 fed from the supply reel 17 in the cassette 10 so as to be fixed / releasably fixed. By the way, the lateral width of the ACF 2 and the separators 3 and 4 is generally extremely small and difficult to handle, and the banding to the rollers 27 to 33 is troublesome, but by providing the fixing means of the ACF 2 and the separators 3 and 4. , This troublesome work can be eliminated as much as possible.

The cassette 10 is constructed as described above. Next, a method for attaching the ACF 2 using the cassette 10 will be described. First, as shown in FIG. 1, the cassette 10 is set on the main body frame 1. In this state,
As shown in FIG. 1, the first positioning pin 71 and the second positioning pin 72 have the first positioning hole 23 and the second positioning hole 2 respectively.
4 and the cassette 10 is positioned. When the cassette 10 is set in the main body frame 1, the roller 33 pivotally attached to the lever 58 is in the lowered position as shown in FIGS. 4 and 10, and when the cassette 10 is set in the main body frame 1, the tip of the separator 4 is set. The part is located between the roller 33 and the drive roller 77.

Then, by raising the roller 33 as shown in FIGS. 5 and 11, the separator 4 is sandwiched between the roller 33 and the driving roller 77, and the clamper 6 is held.
Release the clamped state by 2,63. When the cassette 10 is set in the main body frame 1 in this manner, the separator 4 is ready to be fed by the roller 33 and the drive roller 77. Of course, when the cassette 10 is set in the main body frame 1, the rotor 65 is rotated to separate it from the blocks 38 and 64, and the fixed state of the ACF 2 and the separators 3 and 4 is released. FIG. 5 shows an initial state in which the cassette 10 is set in the main body frame 1,
In this state, it is assumed that the concave portion 21 of the disc 15 is located at the upper position a, that is, the position detected by the first sensor 73.

Now, in FIG. 5, when the first sensor 73 detects the concave portion 21, the motor 78 (FIG. 1) is driven, the drive roller 77 starts to rotate, and the separator 4 indicates the arrow N.
It is sent in four directions (see also FIG. 11) and sent out from the sending section 35 to the box 8 by the roller 33 and the drive roller 77. When the separator 4 is fed in the direction of the arrow N4, the disc 1
5 is pulled by the separator 4 and rotates in the N2 direction, and the recess 21 is detected by the second sensor 74 at the position b. Then, the rotation of the drive roller 77 is stopped and the delivery of the separator 4 is also stopped. At the same time, as shown in FIG.
As shown in FIG. 9B, the chuck claw 82 enters the cassette 10 from the lead-out portion 11 and chucks the tips of the ACF 2 and the separator 3.
As shown in (a) and (b), the ACF 2 and the separator 3 are pulled out by moving to the right. At this time, the disk 15 is a weight 1
8 rotates in the N1 direction and the guide pin 31 also rotates in the N1 direction. Therefore, in FIG.
It is pulled in five directions and is peeled from the ACF 2 while circling along the peeling pin 34 (FIG. 7). That is, this means pulls the separator 4 in the direction of arrow N5 in FIG. 7 by rotating the disk 15 in the direction of arrow N1 by the weight of the weight 18 in FIG. Is separated from the ACF 2, and therefore the separator 4 can be stably separated from the ACF 2 by the rotational force of the disc 15.

As the disk 15 rotates in the N1 direction as described above, the recess 21 is again detected by the first sensor 73. Then, the drive roller 77 starts rotating again, and the above-described operation is repeated. During the above operation, ACF
The detection sensor 75 confirms the presence of ACF2. Here, if the ACF 2 is not detected, it means that the ACF 2 is out of stock or some abnormal situation has occurred. In this case, a signal from the ACF detection sensor 75 drives a notification means (not shown) such as a buzzer to notify the operator to that effect and stop the operation of the apparatus. If the ACF 2 is out of stock, the ACF 2 is replaced with the cassette 10 in which a new supply reel 17 is mounted.

In the first embodiment described above, the ACF 2 has a three-layer structure in which both sides are sandwiched by the separators 3 and 4, but there is also a two-layer structure in which one separator is interposed. Therefore, a cassette for a two-layer structure will be described next. 12
Is a front view showing the internal structure of the cassette of the second embodiment of the present invention, and FIGS. 13 (a) and 13 (b) are front views of the vicinity of the outlet of the cassette during the pulling operation. In each figure, the same parts as those in the first embodiment are designated by the same reference numerals. In FIG. 12, 10a is a cassette, and the following components are arranged on the main plate 12a. Reference numeral 95 denotes a rotation restricting member of the supply reel 17, which is pivotally attached to the pin 96 and is urged by the spring 97 to elastically contact the supply reel 17.
A stopper 98 defines the rotation limit of the rotation restricting member 95. An under block 99 as a supporting member is provided below the block 38. In the second embodiment, the separator 4 is not provided, and the ACF 2 and the separator 3 have a two-layer structure.

Therefore, as shown in FIG. 13 (a), the separator 3 is lightly vacuum-adsorbed by the block 38, and in this state, as in the case shown in FIG. 8 and FIG.
Enters the lead-out section 11, chucks the ACF 2 and the tip of the separator 3, and pulls out from the cassette 10a. At that time, the rotation restricting member 95 prevents the supply reel 17 from excessively rotating in the pull-out direction to loosen the ACF 2 and the separator 3.

When the vacuum suction by the block 38 is stopped or the cassette 10a is removed from the main body frame 1, the ACF 2 and the separator 3 are removed as shown in FIG. 13 (b).
Will hang downwards, so underblock 99
The CF2 and the separator 3 are supported so as not to hang down.

FIG. 14 is a front view showing the internal structure of the cassette of the third embodiment of the present invention, and FIGS. 15 (a) and 15 (b) are front views of the vicinity of the outlet of the cassette during the pulling operation. In the cassette 10b of this embodiment, the block 38a and the under block 99a are horizontally long, and the plate body 43 and the column 41 of FIG. 12 are omitted. The groove 39a is formed up to near the tip of the separator 3, and therefore the block 38a is formed.
By vacuuming the vicinity of the tip of the separator 3, the ACF 2 and the tip of the separator 3 are positioned.
When the vacuum suction state is released, the ACF 2 and the separator 3 are supported by the under block 99a so that they do not hang down. That is, the block 38a and the under block 99a also serve as positioning means for the ACF 2 and the tip of the separator 3.
