<P>PROBLEM TO BE SOLVED: To stabilize caulking quality in heat caulking for deforming a projection of resin by applying heat and a pressing force thereto. <P>SOLUTION: A heat-caulking device includes an action end 7 directly contacting a caulking portion, a caulking head 3 which supports the action end 7, and is linearly moved by driving of an actuator so as to approach to/separate from the caulking portion, a detection means 31 which detects the abutting when the action end 7 abuts to the caulking portion at the normal position for heat caulking, a storage means for storing the position of the action end 7 in abutting, a comparative means for comparing the position of the action end 7 for each time and the position stored by the storage means when the action end 7 repeatedly abuts to a caulking portion having the same shape as the caulking portion, and a controller for stopping caulking action according to the comparative result of the comparative means. <P>COPYRIGHT: (C)2010,JPO&INPIT |
