JOINING DEVICE AND JOINING METHOD (AS AMENDED)

摘要

There is provided a technique that readily performs positioning of a joining member relative to a strip member during conveyance. A joining device 100 joins a gas diffusion layer 7 with a first catalyst electrode layer 2 of a strip body 5r which is a continuous strip member of a membrane electrode assembly 5, while conveying the strip body 5r. A controller 101 of the joining device 100 obtains a detection time td based on a detection signal of a catalyst layer detector 130 when a front end 3e of a second catalyst electrode layer 3 placed on the strip body 5r passes through a detection point DP. The controller 101 subsequently obtains a joining position reach time tt based on the detection time td when the gas diffusion layer 7 reaches a press point PP of joining rollers 152. The controller 101 starts conveying the gas diffusion layer 7 by means of a transfer at a conveying start time ts that is obtained based on the joining position reach time tt and a specified speed pattern of the transfer 141.

主权项

1. A device that continually joins a plurality of joining members with a strip member, the device comprising:
a first conveying assembly configured to convey in a longitudinal direction the strip member on which a plurality of placement members as indications of joining positions of the joining members are arrayed in the longitudinal direction; a second conveying assembly configured to convey the joining members to be joined with the strip member conveyed by the first conveying assembly; a joining roller configured to apply pressure to the strip member and each of the joining members and join the joining member with the strip member at a meeting point of the strip member and the joining member; a detector configured to detect passage of each of the placement members at a predetermined detection point on a conveyance path of the strip member; a conveyance controller configured to control the first conveying assembly and the second conveying assembly and determine a reach time when each of the joining members reaches the meeting point by the second conveying assembly, based on a detection time when passage of each of the placement members is detected by the detector; and a parameter acquirer configured to obtain a parameter related to an expanding or contracting state of the strip body, wherein the conveyance controller changes the detection time according to the parameter and determines the reach time based on the changed detection time.
