Joined member manufacturing apparatus, method for manufacturing joined member, and method for manufacturing member on which applied material has been applied

A method for manufacturing a joined member in which two application target members are adhered to each other by using an application device,

• the application device comprising a die head,
• the die head being configured to apply an applied material onto an application target surface of an application target member by ejecting the applied material onto the application target surface during relative movement of the die head along the application target surface,
• the die head comprising
• a first head constituting member comprising a first opposing face formed on the first head constituting member, and
• a second head constituting member comprising a second opposing face formed on the second head constituting member, the second opposing face contacting the first opposing face,
• wherein the first opposing face comprises an ejection port forming groove formed in the first opposing face, the ejection port forming groove forming a narrow, elongated ejection port through which the applied material is ejected to outside the die head,
• wherein a distance between the ejection port forming groove and an outer edge of the first opposing face is 0.1 mm to 1.0 mm, the distance being at a position where the ejection port is formed in a direction in which the ejection port is elongated;
• the application device further comprising:
• a placement table on which at least one of the application target members is placed, and
• a position confirmation device configured to ascertain a position of the application target member placed on the placement table relative to the die head,
• the method comprising:
• a placing step of placing at least one of the application target members onto the placement table;
• an applying step of, using the die head, applying the applied material onto the application target surface of the application target member placed on the placement table;
• and
• an adhering step of adhering the two application target members having received application of the applied material to each other in a manner in which the applied material applied on one application target member and the applied material applied on the other application target member are brought into contact with each other.

A method for manufacturing a member on which an applied material has been applied, the method comprising:

• a first applied film forming step of forming a first applied film, by a die head, onto an application target surface of an application target member,
• the die head being configured to apply an applied material onto the application target surface of the application target member by ejecting the applied material onto the application target surface during relative movement of the die head along the application target surface,
• the die head comprising
• a first head constituting member comprising a first opposing face formed on the first head constituting member, and
• a second head constituting member comprising a second opposing face formed on the second head constituting member, the second opposing face contacting the first opposing face,
• wherein the first opposing face comprises an ejection port forming groove formed in the first opposing face, the ejection port forming groove forming a narrow, elongated ejection port through which the applied material is ejected to outside the die head,
• wherein one face of the die head has a protrusion protruding outward from the face, the ejection port being formed on a tip end of the protrusion, and
• wherein an end portion thickness of the die head as a distance between the ejection port forming groove and an outer edge of the first opposing face is 0.1 mm to 1.0 mm, the distance being at a position where the ejection port is formed in a direction in which the ejection port is elongated,
• wherein in the method, the first applied film is the applied material having a first predetermined length, the first applied film being formed by the die head ejecting the applied material through the ejection port, the die head ejecting the applied material while being in relative movement along the application target surface;
• the method further comprising:
• a die head moving step of, in a state where ejection of the applied material from the die head has been stopped after the first applied film forming step, moving the die head in an intersecting direction intersecting with a direction of the relative movement of the die head in the first applied film forming step;
• and
• a second applied film forming step of, after the die head moving step, forming a second applied film onto the application target surface of the application target, the second applied film being the applied material having a second predetermined length, the second applied film being formed by the die head ejecting the applied material through the ejection port, the die head ejecting the applied material while being in relative movement along the application target surface;
• wherein in the die head moving step, the die head is moved in the intersecting direction in a manner in which a shortest distance between a track of the ejection port in forming the first applied film and a track of the ejection port in forming the second applied film is 2 mm or smaller.
