[0054] The connector terminal pin coplanarity hot melting device is applied as follows:

[0055] The connector 100 is placed on the limiting groove 21 of the carrier 20, and then the carrier 20 is moved to the corresponding positions of the glue pre-pressing block 32 and the terminal pin pressing block 33.
