2. Description of the Related Art Conventionally, it is known that alignment marks are used for alignment between a liquid crystal panel and a frame prior to joining the frame to a liquid crystal panel. The alignment method is described in, for example, Japanese Patent Application Laid-Open No. H11-109656.
The alignment method described in the above-mentioned publication is, in short, one alignment mark formed in a hollow frame shape having a width equal to the standard value of alignment, and the other alignment mark formed in a circular shape inscribed in the alignment mark. The pass or fail is determined by whether or not the circular alignment mark protrudes from the frame-shaped alignment mark.

[0003]

The alignment using the alignment mark as described above has an advantage that the pass / fail judgment can be easily performed by visual observation or by using a magnifying glass. However, the above publication only proposes an alignment mark for alignment that can determine whether or not the standard is acceptable and can also read the amount of deviation, and describes a visual alignment method using an alignment mark. No proposal has been made as to whether to embody the production technology for panel molded products in such a form.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to align a plurality of panel components using alignment marks, and then to align both panel components. It is an object of the present invention to provide a manufacturing apparatus and a manufacturing method capable of manufacturing a panel molded product by joining with each other.

Means for Solving the Problems In order to achieve the above object, an apparatus for manufacturing a panel molded product according to the present invention has a configuration as described in each claim. According to the first aspect of the present invention, a panel molded product can be manufactured in the following manner. First, the first holding component holds the first panel component, and the second holding component holds the second panel component. Next, the first and second holding members are moved relative to each other from the preset position to the alignment position by relatively moving the first and second holding members. By moving either one of the two holding bases relative to the other in the surface direction, the two panel configurations are formed using the alignment marks provided on the first panel component and the second panel component, respectively. Align materials. This alignment is desirably performed in a state where both panel components are brought as close as possible in order to suppress an adverse effect (illusion) due to a shift in the operator's line of sight. After the alignment, the first holding member and the second holding member are further moved relatively to move the first panel component and the second panel component relatively from the alignment position to the joining position. As a result, the two panel components are overlapped and joined at a predetermined relative position. In this case, a double-sided tape is used, for example, as a joining means of the two panel components.

That is, according to the first aspect of the present invention, after setting the first and second panel components, the first and second panel components are moved to the alignment position, and the alignment is performed in a state of approaching as much as possible. Accurate positioning becomes possible. Here, the first and second panel components are 2
It refers to a panel-shaped component element in the case of forming one panel molded product by superposing parts, and the combination of panel components includes the case of a panel and a panel, the panel and a frame, and the frame and a frame.
