Problems solved by technology

Therefore, when measuring the coating height of the paste, it is sometimes impossible to measure the coating height of the paste with high precision due to the relationship between the arrangement direction of the laser displacement meter and the extending direction of the paste.
In this case, it is difficult to obtain an accurate application height of the paste, and a defective product that has not been applied with the desired application amount may be judged as a good product and used in the next manufacturing process.
As a result, the quality of coated products is reduced

no. 1 Embodiment approach

[0020] refer to Figure 1 to Figure 8 , and the first embodiment will be described.

[0021] Such as figure 1 as well as figure 2 As shown, the paste application device 1 according to the first embodiment includes: a table 2 on which an object W to be applied is placed; and a plurality of application units for applying paste to the object W on the table 2 respectively. 3A to 3D, a plurality of X-axis moving devices 4A and 4B that move the respective coating units 3A to 3D in the X-axis direction, a plurality of supporting parts 5A and 5B that support these X-axis moving devices 4A and 4B, and make these supporting parts Y-axis moving devices 6A and 6B that move 5A and 5B in the Y-axis direction, a stage 7 that supports the table 2, Y-axis moving devices 6A, 6B, and the like, and a control unit 8 that controls each part.

[0022] The table 2 has a mounting surface on which the coating target object W is mounted, and is fixedly installed on the upper surface of the stand 7 ....

no. 2 Embodiment approach

[0067] refer to Figure 9 , and the second embodiment of the present invention will be described.

[0068] The second embodiment is basically the same as the first embodiment. In the second embodiment, differences from the first embodiment will be described, and the same parts as those described in the first embodiment will be assigned the same reference numerals and description will be omitted.

[0069] In the paste coating device 1 according to the second embodiment, the respective coating units 3A to 3D are as follows: Figure 9 As shown, each includes a rotation drive unit 3e that rotates the laser displacement gauge 3c in a direction along the surface to be coated of the object W to be coated, in other words, around an axis perpendicular to the surface to be coated. The rotation drive unit 3 e is electrically connected to the control unit 8 , and its drive is controlled by the control unit 8 . The laser displacement gauge 3c is configured to be rotatable in a direction...

Abstract

PURPOSE: A paste coating apparatus and a paste coating method are provided to improve the quality of a coated product by increasing the measurement accuracy of the coated height of paste. CONSTITUTION: A paste coating apparatus(1) includes a plurality of coating heads(3a), a plurality of laser displacement meters(3c), and a controlling part. The coating heads coat paste on the side to be coated of an object(W). The laser displacement meters are integrated with the coating heads and measure the displacement of the side to be coated. At least one of the laser displacement meters allows an optical path side to follow one straight line of two straight lines in coating patterns. At least one of the laser displacement meters allows an optical path side to follow another straight line of two straight lines in the coating patterns.

Description

technical field [0001] Embodiments of the present invention relate to a paste application device and a paste application method for applying paste to an application object. Background technique [0002] Paste applicators are used in the manufacture of various devices such as liquid crystal display panels. This paste coating device is equipped with a coating head for coating a paste on an object to be coated. While moving the coating head, the paste is applied to the coated surface of the object to be coated to form a predetermined shape on the object to be coated. ointment pattern. For example, in the manufacture of a liquid crystal display panel, a sealant having airtightness and adhesiveness is applied as a paste in a rectangular frame shape to a surface to be coated of an object to be coated such as a substrate. [0003] In such a paste application device, it is possible to obtain the cross-sectional area of ​​the paste applied in a linear pattern to the surface to be a...
