- a polyurethane porous film sheet adhered to urethane rubber with a hardness of 40 with a double-sided tape on the suction plate side, a polyurethane porous film sheet on urethane rubber with a hardness of 80
- the number of cameras in the detection device is not limited to the above number. Only one unit, only two units in the horizontal direction, or only three to four units in the horizontal direction may be sequentially moved up and down. Alternatively, two units may be moved up and down, and moved back and forth. Further, the upper and lower three points may be taken at the same time, and the upper and lower three points may be imaged simultaneously. First, if two points on the diagonal are imaged and there is a point that cannot be extracted from this, another point may be imaged. After imaging four locations, three points may be extracted from three locations where extraction is possible or the image is good. As the number of cameras increases, the mechanism for driving the cameras can be simplified and imaging can be performed at high speed.
- the lower CCD camera 42 is configured such that light from the light source can be vertically irradiated by the prism, and the upper CCD camera 41 receives the light irradiated upward. You may do it.
- the lower CCD camera 42 may be configured to reflect the upper light by the reflecting surface 42a so that the upper and lower images can be imaged and the light from the light source can be irradiated vertically.
- the material of the reflecting surface may be metal, glass, resin, etc., but any material can be used as long as it can reflect the irradiated light.
- the reflection surface may be formed integrally with the camera casing.
- the work to be bonded is typically a cover panel and a liquid crystal module (a laminate of a display panel and a backlight), but can be widely applied as an apparatus for bonding elements constituting a display device. . Therefore, for example, the present invention can also be applied to a case where a touch panel and a liquid crystal module are bonded together.
- Detecting objects for positioning can be changed as appropriate according to the workpiece.
- the workpiece S2 that is the cover panel is bonded to the work S1 that is the liquid crystal module
- the side of the frame H is a portion visually recognized by the user who purchased the product, if the frame H is inclined with respect to the workpiece S1, there is a high possibility that the frame H becomes a defective product.
- positioning by three-point detection is more effective than positioning by two-point detection for the following reasons. That is, since the size and shape of the frame H are formed by printing or the like, there are cases where variations occur for each workpiece S2. For example, as shown in FIG. 42 (A), when the shape of the workpiece S1 and the frame H do not match, even if the two diagonal points are detected and the gravity center and the inclination of the diagonal line are matched, As shown in FIG. 42B, the frame H is positioned with respect to the workpiece S1 in a tilted state.
