Noise reduction vibration welding machine using frequency cancellation

A noise reduction vibration welding machine using frequency cancellation, comprising:

• a head frame (10) in which a vibration spring (11) is provided in a central portion and electromagnetic coils (12) are provided at both side end portions of the vibration spring (11) and which includes an upper end jig (13) at an lower end portion and an upper end fixture (14) under the upper end jig (13);
• a lower frame (20) which supports both side surfaces of the head frame (10), includes a guide shaft coupling part (21) inside an upper portion thereof, and is coupled to guide shafts (22);
• a pressing unit (30) including a work table (31) in which the guide shafts (22) pass through both side end portions of the work table (31), a hydraulic cylinder (32) under the work table (31), a lower end jig (33) on the work table (31), and a lower fixture (34) on the lower end jig (33);
• a soundproof case (40) in which the head frame (10), the lower frame (20), and the pressing unit (30) are installed;
• and
• a noise controller (50) including a noise analyzer (51) on one side surface inside the soundproof case (40), at least one or more speakers (52) facing a noise source at each inner corner, an internal microphone (53) in a central portion of the head frame (10), and a machine acceleration sensor (54) on the electromagnetic coil (12),
• wherein outward speakers (62) are provided in the soundproof case (40) to face the outside where an operator is positioned.
