Abstract
A wiper blade includes a lever assembly that has several types of levers. The levers of each type are efficiently manufactured in the following manner. First, a lever unit, which has a frame bar and several levers integrated with the frame bar, is pressed. Each lever has a hole. Then, a wire is fed through the holes of the levers. The frame bar is separated from the levers to form a hanging unit, which includes the wire and the levers hanging from the wire. In this state, the lever is coated with paint. After the paint is dried, the wire is removed form the levers.
Claims26
A method for manufacturing levers used in lever assemblies of wiper blades, comprising:
- forming a lever unit, wherein the lever unit includes a coupler frame and a plurality of parallel levers integrated with the coupler frame, each lever having a hole;
- feeding a wire through the holes of the levers;
- separating the coupler frame from the levers for forming a hanging unit that includes the wire and the levers hanging from the wire;
- coating the hanging levers with paint;
- and
- removing the wire from the levers after the paint is dried.
A method for manufacturing parts comprising:
- forming a unit of parts, wherein the unit includes a coupler frame and a plurality of parallel parts integrated with the coupler frame, each part having a hole;
- feeding a wire through the holes of the parts;
- separating the coupler frame from the parts for forming a hanging unit that includes the wire and the parts hanging from the wire;
- coating the hanging parts with paint;
- and
- removing the wire from the parts after the paint is dried.
An apparatus for manufacturing parts comprising:
- a forming station for forming a unit of parts, wherein the unit includes a coupler frame and a plurality of parallel parts integrated with the coupler frame, each part having a hole;
- a wire feeding station for feeding a wire through the holes of the parts;
- a separating station for separating the coupler frame from the parts for forming a hanging unit that includes the wire and the parts hanging from the wire;
- a coating station for coating the hanging parts with paint;
- and
- a removing station for removing the wire from the parts after the paint is dried.
An apparatus for forming a hanging unit that includes a wire and a plurality of parts hanging from the wire, wherein, prior to forming the hanging unit, a unit that includes a coupler frame and the parallel parts integrated with the coupler frame is prepared, and wherein each part has a hole, the apparatus comprising:
- a wire feeding device for feeding a wire through the holes of the parts;
- a spacer forming device for forming a spacer with the wire between each adjacent pair of the parts, wherein each spacer prevents the parts of the corresponding pair from contacting one another;
- and
- a separating device for separating the coupler frame from the parts for forming the hanging unit.
