A device and method for inspecting the deposition of hot melt onto an object to be assembled. A comparison is made between sensed images of the object after application of the hot melt and a predetermined standard to determine if the construction integrity of the object made with the hot melt is within the range established by the standard. Composite images from a sensor operating in the infrared band and another sensor reveal physical features of the object, as well as provide registration information about the placement of the hot melt on the assembled object. Composite images also present a way to visually ascertain ongoing or past production operations in order to trace problems with the raw material used for the object, as well as for the construction process of the object with the hot melt.

Methods and apparatus for supporting radio frequency identification tags are disclosed herein. An example apparatus includes a face layer that includes a tag seat, a first extension extending from a first edge of the tag seat, and a second extension extending from a second edge of the tag seat, a third extension extending from a third edge of the tag seat, and a fourth extension extending from a fourth edge of the tag seat. The example apparatus includes an adhesive layer applied to at least a portion an inner surface of the face layer. The example apparatus includes an RFID tag coupled to the tag seat. The RFID tag is to be spaced apart from a surface when outer portions of the first extension and the second extension are coupled to the surface and inner portions of the first extension and the second extension are flexed away from the surface.

A system for use in fabricating a laminate structure from a plurality of layers of material is provided. The system includes a marker coupled to at least two of the plurality of layers, and a positioning system configured to arrange the plurality of layers in a predetermined layup position based on a position of the markers.

An automatic lay-up machine includes a head device and a support mechanism. The head device includes a sheet supplying unit that supplies a prepreg sheet including sheet-shaped prepreg and release paper bonded to a surface of the prepreg, a lay-up unit that lays up the prepreg on a receiving surface by pressing the prepreg sheet against the receiving surface, and a sheet take-up unit that takes up the release paper separated from the prepreg. The support mechanism supports the head device and includes a mechanism for moving the head device in a lay-up direction of the prepreg and a width direction of the prepreg sheet. The head device is moved in the width direction while a position of an edge of the prepreg sheet coincides with a lay-up position and an end portion of the prepreg sheet is pressed against the receiving surface.

The present application thus provides a method of inspecting composite turbine blade spar caps during lay up. The method may include the steps of applying a layer to a mold, measuring a surface characteristic of the layer with a profilometer, and determining if the layer has an out of plane wave therein based on the measured surface characteristic.

Provided are a cutting information determination method that can use a simpler process to improve yield, and a strip-shaped polarizing sheet manufacturing method using such a method, an optical display unit manufacturing method using such a method, a strip-shaped polarizing sheet, and a polarizing sheet material. A cutting position in the width direction A2, in which a polarizing sheet material MP is to be cut along its longitudinal direction A1, is determined based on the numbers of defects counted with respect to plural points in the width direction A2 of the polarizing sheet material MP. This makes it possible to determine the cutting position in such a way that a region with many defects does not fall within the cut width, so that a higher-yield cutting position can be determined. The cutting position can also be determined using a simple process in which defects are counted with respect to plural points in the width direction A2.

A method for manufacturing a liquid-crystal display device in which at least an absorptive polarizing film is arranged on a viewing side of a rectangular liquid-crystal display panel and at least the absorptive polarizing film and a reflective polarizing film are arranged on a non-viewing side thereof, the liquid-crystal display panel having a long side and a short side and of VA mode or IPS mode is provided.

A system for use in fabricating a laminate structure from a plurality of layers of material is provided. The system includes a marker coupled to at least two of the plurality of layers, and a positioning system configured to arrange the plurality of layers in a predetermined layup position based on a position of the markers.

The present invention discloses a lamination device and a control method thereof. The lamination device of the present invention includes a plurality of calibration marks disposed on an upper gripper, a vision camera configured to capture an image of the plurality of calibration marks, a correction driving unit connected to a lower gripper and the upper gripper to correct a height of each of the lower gripper and the upper gripper, and a control unit configured to read the plurality of calibration marks to calculate a positional deviation between an actual position of the upper gripper and a preset allowable position range, and move the lower gripper and the upper gripper to correct the positional deviation.
