An adhesive compression unit for an adhesive coating device is provided to allow an adhesive to be coated with a uniform thickness and to obtain the sufficient wettability with a material. An adhesive compression unit(1) for an adhesive coating device(7) comprises an ascending and descending unit(10) which is mounted integrally to the one side of the body(9) of the adhesive coating device mounted to the front terminal of the arm(5) of a robot so as to ascend and descend a connection rod(11) by the motor control; a press roller unit(20) whose roller housing(21) is mounted to the connection rod of by a buffer member(50) so as to compress and spreading the adhesive coated on the junction part of a material by a coating nozzle(N) of the adhesive coating device by a rotating compressing roller(23); and an adhesive removing unit(30) which is mounted to the one side of the roller housing so as to remove the adhesive adhered on the compression roller.
