Abstract

PURPOSE:To enable a TCP to be mounted on the front and the rear of two glass plates at prescribed positions by a method wherein a liquid crystal display element is fixed to a jig by the single chucking operation of a fixing means, and the fixing means is turned by an angle of 180 deg.. CONSTITUTION:A mounting jig 10 is supported by a pin 20 at a frame 21 in a freely rotatable manner, and a locating pin 23 closely inserted into a hole 22 in a freely slidable manner is inserted into a hole 34, whereby the jig 10 can be fixed. In this state, a TCP(tape carrier package) 2a is mounted on a glass plate 1b of a liquid crystal display element 1. Then, the mounting jig 10 is turned by an angle of 180 deg. to the frame 21, and the locating pin 23 is inserted into the holes 22 and 24 again to fix the jig 10 to the frame 21. By this setup, the liquid crystal display element 1 can be rotated by an angle of 180 deg. and fixed without unclamping the element 1 from a jig, whereby a TCP 2b can be mounted on a glass plate 1a through a hole provided to the mounting jig 10.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an electrode provided on a glass plate of a liquid crystal display element.
TCP (Tape Carrier) is applied to the front and back sides of the liquid crystal display element.
This invention relates to a jig for a liquid crystal display element for efficiently mounting a liquid crystal display element.

[Prior Art] As described in Japanese Patent Application Laid-open No. 61-252692, a conventional method of working on a plate-shaped part from the front and back is to move the plate-shaped part by the thickness of the jig, chuck it again, and then re-chuck it. Later, a method was proposed in which the plate-shaped part was inverted along with the jig.

[Problems to be Solved by the Invention] The above-mentioned conventional technology does not take into account the fact that it targets fragile parts such as parts made of glass plates, and it is difficult to apply the parts to liquid crystal display elements. There was a high risk of damage, and there were problems with product yield.

An object of the present invention is to solve the above-mentioned problems and provide a jig that allows mounting of the front and back sides of a component without having to re-chuck the component once the liquid crystal display element has been chucked onto the jig. It is to provide the ingredients.

[Means for Solving the Problems] In order to achieve the above object, the liquid crystal display element driver IC mounting jig according to the present invention has electrodes formed on each of them, and a certain gap in the direction in which the respective electrical connections face each other. During the assembly process, in which TCPs are mounted vertically and horizontally on two glass plates that are held together and bonded together, and the liquid crystal is sealed in the space formed by the gap, the yield decreases due to damage to the glass plate, which is a brittle material, and Due to the change of TCP installation work,
In order to eliminate the need to replace jigs for the liquid crystal display element and make it compatible with automation, we provided a liquid crystal display element fixing means to chuck the liquid crystal display element, and an opening for performing TCP mounting work from the front side. The fixing means is provided in the liquid crystal display element fixing means, further fixing the liquid crystal display element.
A fixing means for rotating and fixing by 0° is provided, and the TCP can be mounted on the front and back sides of two glass plates of the liquid crystal display element by chucking the liquid crystal display element once.

[Function] The above-mentioned liquid crystal display element driver IC mounting jig fixes the liquid crystal display element made of a fragile glass plate to the jig with one chuck operation, and then rotates the fixing means 180 degrees while maintaining the state A. By fixing it, TC is applied to the front and back of the two glass plates.
It is possible to mount each P in a predetermined position.

[Embodiment] FIG. 1 is a plan view showing an embodiment of a mounting jig for a liquid crystal display element driver 1C according to the present invention.

FIG. 2 is a sectional view taken along line AA' in FIG. Similarly, the third
The figure is a sectional view taken along BB' in FIG.

FIG. 4 is a plan view showing a state in which the liquid crystal display element fixed to the mounting jig as shown in FIG. 1 has been rotated by 180 degrees together with the mounting jig.

FIG. 5 is a sectional view CC' of FIG. 4.

FIG. 6 is a perspective view of the liquid crystal display element before mounting TCPs thereon, and FIG. 7 is a perspective view showing a state in which a plurality of TCPs and Ps are mounted on the liquid crystal display element.

As shown in FIG. 6, the liquid crystal display element 1 has two glass plates 1a and 1b, upper and lower, which are fixed at a constant distance from each other, and liquid crystal is sealed in the space formed by the distance.

On the other hand, on the opposing surfaces of the two glass plates 1a and ]b, a pair of transparent electrodes for applying voltage to control the arrangement of the liquid crystals is formed, each corresponding to a pixel of the display element. So, crow board 1a.

]b has been pulled out to step portions c and d.

A TCP 2a is mounted on the glass plate [b] of the liquid crystal display element 1 from above as shown in FIG. 7, and a TCP 2b is mounted on the glass plate 1a from below in this figure.

According to FIGS. 1 to 3, the liquid crystal display element driver 1C
The configuration and function of the mounting jig will be explained.

The position of the liquid crystal display element 1 in the X direction is determined by a positioning part 11 in the X direction in the figure provided on the mounting jig 10,
Place the clamp block 12 along the guide pad 13 and attach the spring 14.
It is clamped by a force pushing it in the X direction.

On the other hand, in the Y direction, the position in the Y direction is determined by a Y direction positioning part 15 provided in a part of the mounting jig 1o, and the mounting jig 1o is pressed and clamped in the Y direction by an eccentric cam 16.

Further, the mounting jig 10 is rotatably supported by the frame 21 by pins 20, and the mounting jig 10 is rotatably supported by the frame 21.
By inserting the locate pin 23, which is slidably inserted into the hole 22 formed in the mounting jig 10, into the hole 24, which is large enough to be slidable without any gap between the locate pin 23 formed in the mounting jig 10, It can be fixed without rotating.

In this state, TCP2 is placed on the glass plate lb of the liquid crystal display element 1.
a is mounted as shown in FIG.

Next, when mounting the TCP 2b on the part 1a in FIG. 6, remove the locating pin 23 shown in FIGS. The mounting jig 10 is fixed to the frame 21 by rotating and inserting the locate screw 23 into the respective holes 22 and 24 of the frame 21 and the mounting jig 10.

It goes without saying that the positions from the pin 20 to the hole 22 in the frame and the hole 24 in the mounting jig are exactly symmetrical on the left and right sides.

In this way, the liquid crystal display element 1 can be rotated 180 degrees and fixed without removing the clamp from the jig for the liquid crystal display element l. It can be installed on.

〔Effect of the invention〕

As explained above, the liquid crystal display element Drim I of the present invention
By using the C mounting jig, when mounting TCP on the front and back sides of liquid crystal display elements, which are fragile due to crows, it is possible to remove the liquid crystal display element and flip it 180 degrees without having to remove it, thereby preventing a decrease in yield due to glass breakage, etc. It is possible to
The on-line mounting equipment also has the advantage of being able to supply liquid crystal display elements without human intervention.
