Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an anisotropic conductor sticking apparatus and an anisotropic conductor sticking method.

[0002]

2. Description of the Related Art In a method of mounting an electronic component on a work such as a liquid crystal panel, an anisotropic conductor sticking apparatus for sticking an anisotropic conductor to a work is used. This anisotropic conductor sticking device includes a device for sticking an anisotropic conductor substantially equal to the length of a workpiece, and a device cut short to one or several electronic components. There is a method in which an anisotropic conductor is repeatedly applied to one side of a work a plurality of times.

The problem of the prior art will be described with reference to FIG. 12 by taking the latter type of anisotropic conductor sticking apparatus as an example.

In FIG. 12, reference numeral 1 denotes a substrate, which corresponds to a work to which an anisotropic conductor shorter than this length is to be attached. Reference numeral 2 denotes a crimping tool, a tape 3 having an anisotropic conductor 4 cut to a predetermined length attached to one surface.
Is attached to the substrate 1 by descending in the direction of the arrow N1. Then, when the anisotropic conductor 4 cut into a predetermined length by the crimping tool 2 is attached, both sides of the crimping tool 2 are provided on both sides of the crimping tool 2 so that the anisotropic conductor 4 is in a horizontal posture.

In fact, according to this type of anisotropic conductor sticking apparatus, as shown in FIG. 12A, the crimping tool 2 and the guides 5 and 6 are always positioned horizontally. , Cannot be lowered together. This is because, if such a configuration is adopted, the guide bodies 5 and 6 collide with the substrate 1 and the substrate 1 is damaged. Incidentally, since the substrate 1 is usually made of a material such as glass which is easily damaged, it is necessary to avoid direct contact between the guide members 5 and 6.

For this reason, as shown in FIG. 12B, the guide members 5 and 6 are inevitably lifted from the substrate 1 by a height H, and only the crimping tool 2 is lowered as shown by a chain line. It will be pasted. However, in this case, the anisotropic conductor 4 cut to a predetermined length is positioned with respect to the crimping tool 2 before attaching (see the solid line), and the tape 3 is restrained by the guide body 5 side. Therefore, when the crimping tool 2 is lowered, a shift ΔL occurs.

Is lost, and a rotation difference is generated between the second shaft 48 and the first shaft 47. That is, the slip clutch 52
, It is possible to prevent excessive tension from acting on the tape 3 wound on the take-up reel 23 even if a simple control of constantly driving the third motor 37 is employed.

Next, each step of the anisotropic conductor sticking method of the present embodiment will be described with reference to FIGS. First,
As shown in FIG. 5, the anisotropic conductor 4 is cut. At this time, the rod 33 of the cylinder 32 is retracted,
The lower surface of the crimping tool 19 is substantially at the same height as the guides 20 and 21, and the crimping tool 19 sucks the other surface of the tape 3 by the suction path 19a. Therefore, the tape 3 below the crimping tool 19 takes a horizontal posture. Then, as shown by the arrow M1, the cutter 17 is operated to cut the anisotropic conductor 4 at predetermined lengths. As shown in FIG. 5, in the state before the cutter 17 is operated, the two anisotropic conductors 4x and 4y are already cut downstream from the position of the cutter 17, so that the front row is different. Isotropic conductor 4x
Is located directly below the crimping tool 19 so that the feed rollers 22
Is sent and positioned. At this time, crimping tool 1
9 has a high temperature due to the heat generated by the heater H, and the anisotropic conductor 4x has been heated in advance.

Next, as shown by an arrow N2 in FIG. 6, the feed roller 22 is rotated in the reverse direction, and the tape 3 between the pressure bonding tool 19 and the feed roller 22 is displaced by the above-described displacement ΔL.
Sag (arrow M3).

Then, as shown in FIG.
To advance the crimping tool 19 to the substrate 10 side,
The anisotropic conductor 4x is temporarily attached to the substrate by heat and pressure (arrow M4). At this time, the tape 3 on the upstream side of the crimping tool 19
Is pulled to the suction body 16 side by the tension of the suction body 16, but the suction force (holding force) by the crimping tool 19 is stronger than the tension, so that the arrow M <b> 6
Move by ΔL as shown by. In addition, the tape 3 on the downstream side
Has already slacked by ΔL downstream of the crimping tool 19 by the return operation of the feed roller 22, so that the crimping tool 1
Even if 9 falls, it is not pulled as shown by arrow M5. Therefore, excessive tension acts on the portion of the tape 3 sucked and held by the crimping tool 19, and the tape 3 in this portion is
When the anisotropic conductor 4x lands on the substrate 10, the anisotropic conductor 4x is positioned with respect to the crimping tool 19 as shown in FIG. The positional relationship is the same as when it was performed. That is, by returning in advance in the reverse direction by the Δ shift L, the shift ΔL described in the section of the related art is canceled, and the crimping tool 1
This is to prevent the tape 3 sucked by the crimping tool 19 from being displaced when the 9 moves down.

After this crimping is completed, as shown in FIG.
The crimping tool 19 is retracted to almost the same height as the guide members 20 and 21. At the same time, the second motor 34 is stopped, the downstream side of the tape 3 is clamped by the feed roller 22 and the urging roller 35, the drive unit 40 is operated, and the roller 42 is used as shown by an arrow M8. And push only the tape 3 to the downstream side. On the other hand, the anisotropic conductor 4x is
When the roller 42 passes below the crimping tool 19, the roller 42 moves and the substrate 10 is pressed.
The tape 3 is cleanly peeled off from the anisotropic conductor 4x crimped on the tape (FIG. 9).

At this time, the block 41 is located immediately below the lower surface of the crimping tool 19. At this time, as shown in FIG. 10, the tape 3 directly above is inspected by the anisotropic conductor detection sensor 43 provided in the block 41. As a result of this inspection, if the anisotropic conductor 4x is not detected on the tape 3, it is interpreted that the crimping was successful, and if the anisotropic conductor 4x was detected, the crimping failed and the operation was abnormal. Is interpreted as In addition, in order to check the success or failure of the crimping, the sensor 43 is mounted on the block 41 upside down and the substrate 10 is
Inspection at 3 may be interpreted as normal if the anisotropic conductor 4x is present on the substrate 10 or abnormal if not. Here, in the state shown in FIG. 9 and FIG.
Is adsorbed on the other surface. Also, due to the tension of the suction body 16, the upstream side of the tape 3 is
Immediately after being peeled off from x, the distance 2 ·
Move upstream by ΔL.

Next, as shown in FIG. 11, preparations for the crimping operation are performed. That is, the block 41 and the roller 42 are retracted, and the feed roller 22 is rotated in the forward direction as shown by the arrow M10 to feed the tape 3 to the downstream side.
The feed amount at this time is L + ΔL, where L is the length of the anisotropic conductor 4x (4y). Thus, the next anisotropic conductor 4y is positioned with respect to the crimping tool 19. Further, the substrate positioning table 8 is driven so that the arrow M
As shown by 11, the substrate 10 is moved so that the place where the next anisotropic conductor 4y should be crimped is directly below the crimping tool 19. As a result, the positional relationship shown in FIG. 5 is obtained, and the above operation is repeated, so that the anisotropic conductor 4 can be successively pressed on the substrate 10.
