Problems solved by technology

[0005] In addition, the die head has a manifold for temporarily storing the coating liquid. When the air bubbles in the manifold exceed a certain amount, the discharge pressure of the coating liquid will cause the shrinkage of the bubbles to increase, resulting in a poor response to the discharge of the coating liquid.

Embodiment Construction

[0026] Hereinafter, an embodiment related to the die head of the present invention will be described. figure 1 It is a perspective view showing an example of the die head 10 according to the embodiment of the present invention. Such as figure 1 As shown, the die head body 11 is formed by a pair of die head members 12a, 12b sandwiching a backing plate 13 therebetween. The backing plate 13 serves as a member for adjusting the width of the slit 14 when the coating liquid is applied from above the member placed on the coating platform of the coating liquid coating device (not shown). The die head main body 11 has a manifold that can temporarily store a coating liquid as described below, and can supply the coating liquid stored in the manifold to the slit 14 .

[0027] The die head main body 11 is provided with a coating liquid injection part 15 and exhaust parts 16a and 16b. The coating liquid injection part 15 is connected to a coating liquid supply part (not shown) and can ...

Abstract

A die head body (11) is formed by sandwiching, between a pair of die head members (12a, 12b), a shim plate (13) that adjusts the width of a slit (14) through which a coating liquid is applied from above a member that is placed on a coating stage (30) of a coating liquid applying device (27). The die head body (11) has: a manifold (19) for internally storing, as a primary reservoir, the coating liquid in order to supply the same to the slit (14); a coating liquid injecting unit (15) for supplying the coating liquid to the manifold (19); and an air venting unit (16a, 16b) for removing air that is retained in the manifold (19). The die head body further has a leg unit (18) provided at the same height as the height of the distal end position of the slit (14), and a plurality of sensors (17a, 17b) that measure the distance to the surface of the coating stage (30). By virtue of this configuration, a die head (10) and the coating stage (30) can be kept in parallel.

Description

technical field [0001] The present invention relates to a die head and a coating liquid coating method for coating a coating liquid on a member placed on a coating platform of a coating liquid coating device. Background technique [0002] A coating liquid coating device is a device that applies a coating liquid to a member placed on a coating platform, for example, a UV-curable adhesive for bonding two members is applied as a coating liquid Coating liquid coating device. UV-curable adhesives are adhesives that cure when irradiated with ultraviolet rays. [0003] For example, when bonding a liquid crystal panel and a cover glass with a UV-curable adhesive to manufacture a joint member, use a coating liquid coating device to apply the UV-curable adhesive to a part of the bonding surface of both members or one member. . Next, the bonding surfaces of the two members face each other, and the two members are pressurized to spread the UV-curable adhesive to adhere the two member...
