Description

  The present invention relates to a panel bonding method in which, in a manufacturing process of a liquid crystal display panel or the like, the sealing agent applied between two panels is cured by irradiating light to be cured.

  Conventionally, in a manufacturing process of a flat display panel typified by a liquid crystal display panel, there is a bonding operation in which two panels are opposed to each other at a predetermined interval and liquid crystal is sealed between these panels and bonded together with a sealant. Has been done. This bonding operation is performed in the following steps. First, a sealing agent is applied to one of the two panels in a frame shape, and a predetermined amount of liquid crystal is dropped and supplied to a portion corresponding to the inside of the sealing agent frame of that panel or the other panel. Next, the above two panels are held by the upper holding table and the lower holding table and are opposed to each other with a predetermined interval in the vertical direction, and in this state, the horizontal X, Y, and rotation of these panels Position in the β direction, which is the direction, and overlap the two panels. Next, the sealing agent is cured while being held so that the positioning accuracy of the panel is not impaired, and the panels are bonded together.

  A photo-curing type sealant is preferably used. The panel laminating device for performing the sealing process irradiates the panel with light in the wavelength range absorbed by the sealant. As the light source, a high-pressure mercury lamp, metal halide lamp, etc. are used, and the same long lamp is used. A planar light source device that is arranged in parallel with each other on the surface and covers the entire area of the panel is provided, and light is irradiated only to a predetermined region (sealant portion) of the panel through a mask. However, in such an apparatus, it is necessary to produce a mask for each panel size and image frame arrangement pattern, and the efficiency is poor because light is irradiated to an area that is shielded by the mask and is not used.

  In recent years, an apparatus using an LED as a light source instead of the lamp has been proposed. For example, Patent Document 1 discloses a panel bonding apparatus using LEDs. This apparatus includes at least two long linear light sources, and is arranged so that the extending directions thereof are orthogonal to each other. The first illumination unit after the side along the Y direction is cured by the first illumination unit. Is moved and retracted to a position in the X direction that does not interfere with the second illumination means, and then the side along the X direction is cured by the second illumination means. According to this panel laminating apparatus, the position of each linear light source is controlled, and only the sealant part can be irradiated with uniform illuminance, and only the necessary part is irradiated with light. Efficiency is improved without wasting light.

  However, according to the panel bonding apparatus described in the above document, exposure is performed in the order of exposing the seal portion in the Y direction after the exposure of the seal portion in the X direction. For this reason, it is essential to retract all the X direction light sources when performing exposure with the Y direction light source, and a time loss occurs at that time. On the other hand, in the manufacturing process of the display panel, the panel tends to be enlarged in order to reduce the production cost. In the manufacturing process, it is desired to further shorten the tact time. However, in the above apparatus, time loss increases as the panel size increases, and it is difficult to improve productivity.

  In view of the above-described problems, an object of the present invention is to provide a panel bonding method that can shorten the tact time and improve productivity.

  In order to solve the above problems, the invention described in claim 1 is a panel bonding method in which light is irradiated to a work holding an uncured sealant between panels to cure the sealant. The first linear light source and the second linear light source are configured in a linear shape by arranging the point light sources side by side, and the first linear light source is arranged in the X direction. The second linear light source extends in the Y direction and is movable in the X direction, is arranged with different heights to the workpiece, and is independent of each other. It arrange | positions in the state which can move, arrange | positions the said 1st linear light source and the said 2nd linear light source in the position corresponding to the said sealing agent, The said 1st linear light source and the said 2nd The light is irradiated from the linear light source to the workpiece, and the first linear light source and the second Among the linear light sources, the linear light source closer to the workpiece is moved, and the first linear light source and the second linear light source intersect at the time of the light irradiation of the linear light source far from the workpiece. The panel bonding method is characterized in that the point light source corresponding to the position is turned on and the workpiece is irradiated with light.

  According to the panel laminating method of the present invention, when exposure is performed with linear light sources in the X direction and the Y direction, they are different from each other. Therefore, when the first exposure is performed, the panel is disposed at a position far from the panel. As a result of the light from one light source being blocked by the light source located closer to the panel, a second exposure is required, but the amount of movement of the light source closer to the panel may be in a very small range. Therefore, even if the panel is enlarged, the seal can be cured efficiently in a short time.

FIG. 3 is a side view as seen from the A direction in FIG. 2, and FIG. 4 is a side view as seen from the B direction in FIG.

  As shown in FIGS. 1 to 4, in this panel laminating apparatus 100, bases 11 projecting upward are respectively arranged at the four corners of the upper surface of a rectangular frame 30, and between one base 11, 11. A bar-shaped guide 12 extending in the Y direction and a bar-shaped guide 12 extending in the Y direction are also supported between the other bases 11 and 11. Further, four first linear light sources 10 (LX1 to LX4) extending in the X direction are supported between the guides 12 and 12, for example.

Also, a rod-shaped guide 22 extending in the X direction is supported. Further, for example, three second linear light sources 20 (LY1 to LY3) extending in the Y direction are supported between the guides 22 and 22.

  As shown in FIGS. 1 to 4, the first linear light source 10 (LX1 to LX4) and the second linear light source 20 (LY1 to LY3) are perpendicular to each other and extend independently from each other. In order to be able to move, the liquid crystal display panel or the like is arranged such that the distance from the workpiece W is different, that is, the height to the workpiece is different.

  The first linear light source 10 (LX1 to LX4) is supported by a driving unit 101 having a motor mounted therein engaged with a guide 12 extending in parallel, and the driving unit 101 moves along the guide 12. As a result, the support body 102 formed integrally with the drive unit 101 is moved in the Y direction. The support 102 is provided with, for example, one row of light source units 40 described in detail in FIGS. 5 to 6 in the direction in which the support 102 extends (that is, the X direction).

As shown in these drawings, a plurality of, for example, five LED elements 42 (hereinafter referred to as LEDs) are arranged on the LED substrate 41 in a state of being molded in a translucent lens body 44. The translucent lens body 44 has a property of condensing the light emitted from the LED 42 and condensing the light into parallel light on the front opening side. The parallel light emitted from the plurality of translucent lens bodies 44 is controlled and mixed and uniformed by the multi-lens 45 so as to have a predetermined angle component, and further, the Fresnel lens 46 defines a predetermined area of the workpiece W. Superimpose irradiation. It is also possible to use a cylindrical lens or a spherical lens instead of the Fresnel lens 46. Thus, in the panel bonding apparatus according to the present embodiment, the plurality of LEDs 42 and the optical system that controls the light from these LEDs 42 are combined to constitute one point light source. Of course, it can change suitably, without being limited to such an example.

  As shown in FIGS. 5 and 6, the LED board 41 is provided with a power supply unit 47 that supplies power to the plurality of LEDs 42. For example, the pin portion of the power supply unit 47 is the first or second line. The light sources 10 and 20 are inserted into and supported by the supports 102 and 202, and are coupled by power feeding. Such light source units 40 are arranged in a row at a predetermined pitch on the supports 102 and 202 of the first or second linear light sources 10 and 20.

A sequence related to the movement and lighting of the first linear light source 10 (LX1 to LX4) and the second linear light source 20 (LY1 to LY3) from the initial arrangement state of the panel bonding apparatus 100 shown in FIG. 8 is a diagram showing the first linear light source 10 (LX1 to LX4) and the second linear light source 20 (LY1 to LY1) in the period (a) and the period (b) in the sequence of FIG. 7B. It is the figure which extracted and showed the lighting of LY3) and the movement state.

  Px1 to Px8 and Py1 to Py6 described in FIG. 7A indicate positions where a sealing agent is applied between the panels. That is, according to the description of FIG. 7A, it is assumed that a total of 12 panels of 3 × 4 are produced from one set of substrates. 7A shows a state in which the linear light sources 10 and 20 are viewed from the work W side (from bottom to top). In FIG. 7B, the vertical axis indicates the first linear light source 10. Symbols and horizontal axes corresponding to (LX1 to LX4) and the second linear light sources 20 (LY1 to LY3) are time (arbitrary units).

The sequence of FIG. 7B will be described with reference to FIGS.
First, when the workpiece W is disposed immediately below the display panel bonding apparatus 100, a control unit composed of a computer or the like in which a program for sequence control (not shown) is built in causes the drive units 101 and 201 to receive a sealant. Position data is sent. In accordance with this data, the first linear light source 10 (LX1 to LX4) and the second linear light source 20 (LY1 to LY3) are driven, and the first and second linear light sources 10 and 20 are moved to their initial positions. It arrange | positions (FIG. 7 (a), FIG. 8 (a)). That is, the first linear light sources 10 (LX1 to LX4) are arranged at positions Px1, Px3, Px5, and Px7 corresponding to the right end portion of each panel, and the second linear light sources 20 (LY1 to LY3) are It arrange | positions at the position of Py1, Py3, and Py5.

  Next, after the first linear light source 10 (LX1 to LX4) and the second linear light source 20 (LY1 to LY3) are arranged at the predetermined positions, the power feeding unit is used according to the data from the control unit. Electric power is supplied from 47 to each light source, and the work W is irradiated with light for the first time. At this time, in the second light source 20 (LY1 to LY3) close to the workpiece W, all of the light source units 40 are turned on (all ON) (see FIG. 8B), and the first linear light source 10 (LX1 to LX1). For LX4), the vicinity of Py1, Py3, and Py5 shielded by the second linear light source 20 (LY1 to LY3) is turned off, and only the other portions are lit (ON) (FIG. 8C).

  Next, after the first light irradiation, data is sent from the control unit to the drive units 101 and 201, and the second linear light sources 20 (LY1 to LY3) move from the positions of Py1, Py3, and Py5. (FIG. 8D).

  Next, after the minute movement of the second linear light source 20 (LY1 to LY3), the second linear light source 20 (LY1 to LY3) is turned off from the power supply unit 47 in accordance with the data from the control unit ( In FIG. 8E, power is supplied only to the light source unit 40 that was previously in the OFF state in the first linear light sources 10 (LX1 to LX4) (FIG. 8F). As shown in FIG. 8D, the light from the first linear light source 10 (LX1 to LX4) is not shielded because the second linear light source 20 (LY1 to LY3) is not below. Light is irradiated to the workpiece W. As a result, the Px1, Px3, Px5, Px7 and Py1, Py3, Py5 portions of the workpiece W are irradiated with light without insufficient illuminance, and the sealing agent is surely secured. Can be cured.

  Thereafter, data is sent from the control unit to the drive units 101 and 201, and the first linear light sources 10 (LX1 to LX4) are located at positions Px2, Px4, Px6, and Px8 corresponding to the left end portion of each panel. At the same time, the second linear light sources 20 (LY1 to LY3) are moved to the positions of Py2, Py4, and Py6.

  After the moving arrangement, all the light source units 40 are turned on (all ON) in the second linear light sources 20 (LY1 to LY3) close to the workpiece W, and the first linear light sources 10 (LX1 to LX4) The power is supplied from the power supply unit 47 according to the data from the control unit so that the Py2, Py4, and Py6 regions that are shielded by the two linear light sources 20 (LY1 to LY3) are turned off and only the other portions are turned on (ON). Supplied.

  After that, when data is sent from the control unit to the drive unit 201 and the second linear light sources 20 (LY1 to LY3) move from the positions of Py2, PY4, and PY6, the first linear light source 10 (LX1). To LX4), power is supplied from the power supply unit 47 in accordance with the data from the control unit so that the vicinity of Py2, Py4, and Py6 turned off is turned on (ON).

  In this way, the first linear light source 10 (LX1 to LX4) extending in the X direction and the second linear light source 20 (LY1 to LY3) extending in the Y direction are simultaneously irradiated, and only the light source close to the workpiece W is irradiated. It moves slightly and only the necessary part of the light source far from the workpiece W is turned on. By performing such lighting control, it is possible to reduce the amount of movement when irradiating light from the first time to the second time, and it is possible to increase the speed of the panel bonding process. Of course, the sealing agent of the workpiece W is irradiated with light without insufficient illuminance, so that the sealing agent can be reliably cured.

  In the above panel bonding apparatus, the linear light source far from the workpiece may be turned on at the first light irradiation. However, even if it is lit, even a slight amount of the light is shielded, so that the sealing agent becomes uncured and causes a defect. Therefore, the second light irradiation is indispensable for the shadowed portion of the light source far from the work. Therefore, at the time of the first light irradiation, no power is supplied at the time of the first light irradiation, and the portion that may be shaded by the other linear light source and may become a shadow is not supplied at the time of the second light irradiation. Only by lighting up, it is possible to realize a reliable and efficient panel bonding method.
