Next, the operation of the mounting device 114 will be described. FIG. 8 is a flow chart showing the mounting process of the mounting apparatus.

First, the first mark distance before crimping BD1 and the second mark distance before crimping BD2 are acquired based on the image from the imaging device 145 (S101: first distance acquisition step).

Next, the electrode information acquisition unit 415 acquires electrode information from the storage unit 411 or the like (S102: electrode information acquisition step).

Next, the existing difference value DV is acquired (S103), and the difference value DV is newly acquired as the amount of change in the second direction between the first member 201 and the second member 202 to be mounted next by the mounting device 114. Based on the obtained pre-crimping first mark distance BD1, the newly obtained pre-crimping second mark distance BD2, and the obtained electrode information, the change amount derivation unit 417 derives the change amount YV (S104: change amount deriving step).

Next, based on the amount of change YV, other correction values, electrode information, etc., the position control unit 418 controls the position adjusting means 117 so as to ensure conduction between the first electrode 211 and the corresponding second electrode 212. First, the positional relationship between the first member 201 and the second member 202 is adjusted based on the image from the imaging device 145 (S105: control step).

Next, the second member 202 is attached to the first member 201 by the attachment device 114 (S106: attachment step).

Next, the first member 201 and the second member 202 attached by the attaching device 114 and conveyed by the conveying device are thermo-compressed by the crimping device 115 to establish electrical connection between the first electrode 211 and the corresponding second electrode 212. Secure (S107: crimping step).

Next, based on the first member 201 and the second member 202 that are thermocompressed, the first distance BD1 between the first mark 221, the second distance BD2 between the second marks 222, and the first member 201 and the second member 202 are measured. is obtained by the second distance obtaining means 105, which is an inspection machine (S108: second distance obtaining step).

Next, the difference calculator 416 calculates the difference between the dimensional change amount of the first electrode 211 and the dimensional change amount of the second electrode 212 as the difference value DV (S109: difference calculation step).

Next, the derived amount of change YV is fed back to the position control section 418 as a correction value (S110).

By adopting the above method, even if at least one of the first member 201 and the second member 202 is stretched in the first direction by thermocompression bonding, the amount of change YV can be derived and the first member 201 and the second member 202 can be It can be fed back to the step of attaching the two members 202 . Therefore, by adjusting the distance in the second direction between the first member 201 and the second member 202 to be attached next in anticipation of elongation due to thermocompression bonding, an appropriate conduction point can be secured after thermocompression bonding. This makes it possible to stably supply products. In particular, when both the material of the first member 201 and the material of the second member 202 are resin, the difference in elongation due to thermocompression bonding becomes large, and the difference in elongation varies depending on the environment. Stable manufacturing of the product is possible by feeding back to the position adjustment at the mounting stage based on the above.
