Detachable and foldable integrated organ and process for manufacturing keyboard thereof

A process for manufacturing an organ keyboard, characterized by comprising a step of producing the keyboard, a step of producing conductive films, and a step of assembling the conductive films and the keyboard, wherein

• the step of producing the keyboard includes:
• a step of mixing and kneading of silica gel, in which ingredients are prepared by weight ratios and mixed internally by a kneader, then mixed by an open mill and a vulcanizer and packaged, and finally cut into sheets of silica gel according to the desired standard thickness;
• a step of molding of silica gel, in which, in mold-locked production employing a two-layer die, the silica gel is fed to the lower-layer die and vulcanized, and then excessive burrs are removed from keys of silica gel after the vulcanization;
• and
• a step of surface treatment, in which a screen and a screen printing clamp are positioned on a screen printing machine, then the keys of silica gel are placed on the screen printing clamp for surface screen printing and then dried using an elevated temperature tunnel;
• the step of producing conductive films includes:
• a step of baking of the substrate, in which the substrate of the conductive film is baked within an oven;
• a step of screen printing of lines, in which firstly the substrate is put on the screen printing machine and positioned with respect to the screen, a shielding net of the conductive film is screen printed using silver paste or carbon paste and dried in a drying tunnel, then main lines are screen printed using silver paste or carbon paste and dried, and subsequently, bridges, i.e. intersections in the lines, are screen printed with insulating oil and solidified in a UV tunnel, then the keys and jumpers are screen printed using silver paste or carbon paste and dried in the drying tunnel, then isolation points and bathers are screen printed and solidified in the UV tunnel, and finally the screen printed conductive films are dried;
• and
• the step of assembling conductive films, in which a first conductive film and a second conductive film are assembled in alignment and perforated, and then trimmed in shape.
