Method for manufacturing glass beads using waste glass and glass beads

A method for manufacturing glass beads using waste glass, the method comprising the step of:

• a) separating waste glass (G) from a waste solar panel,
• wherein the step a) includes a process of heating the waste solar panel to a first predetermined temperature and a process of cutting an adhesive surface between the waste glass (G) and a backsheet (BS) of the waste solar panel using a knife (N) of a cutting means heated to a second predetermined temperature,
• wherein the cutting means in the step a) comprises:
• a main body (N1) installed to be movable up and down within a first removal section (A331);
• a knife (N) mounted at a front end of the main body (N1);
• and
• a heating unit (N2) embedded in the main body (N1) to heat the knife (N),
• wherein an anti-loosening bolt (B) that secures the knife (N) to the main body (N1) includes:
• a pull-out hole (B1) formed along the anti-loosening bolt's longitudinal direction;
• and a core member (B2) that is inserted into the pull-out hole (B1) and elastically supported toward a head (Ba) direction,
• wherein the anti-loosening bolt (B) is provided locking pieces (B21) hinge-coupled along edge of a tip of a threaded portion (Bb) to rotate outward and having a length that slightly protrudes from an outer surface of the threaded portion (Bb),
• wherein an anti-loosening fastening hole (H) provided in the main body (N1) is connected to a lift groove (H2) where no threading is formed, extending from a bottom of a threaded part (H1), and includes a pressure plate (H2) elastically supported in the lift groove (H2) toward the threaded part (H1), and
• wherein, when the anti-loosening bolt (B) is inserted through the knife (N) and fastened into the anti-loosening fastening hole (H), the locking pieces (B21) are forcibly fitted into the inner surface of the lift groove (H2), and the pressure plate (H2) elastically presses the anti-loosening bolt (B) outward, functioning as a washer.
