Abstract
An apparatus for forming the leads of electrical components such as five-leaded TO-220 packages is provided. Taped components are supplied from a reel to a sensor which detects the presence of an electrical component contained on the tape, and stops advancement of the tape. While the tape is stopped, a cutter singulates a segment of tape having at least one electrical component from the remainder of the tape. The singulated tape is then advanced through a lead forming station, where the leads of the electrical component are formed into the desired configuration. A method is also disclosed for forming the leads of electrical components supplied on a roll of tape.
Claims12
Apparatus for forming the leads of electrical components contained on a tape, the apparatus comprising:
- a sensor for detecting the presence of an electrical component contained on the tape;
- means for singulating a segment of tape having at least one electrical component from the remainder of the tape after the sensor detects the presence of an electrical component;
- a lead forming station adapted to accept the segment of tape and to form the leads of the electrical component contained on the segment into a desired configuration;
- the tape being stored in a reel prior to delivery to the sensor, the tape having a section extending from the reel to the sensor;
- a motor drivingly connected to the reel to maintain slack in the section generally constant;
- and
- means for detecting slack in the section, the means for detecting slack in the section comprising a paddle engaged with the section and movable as the slack in the section varies, the paddle activating the motor upon moving to a predetermined position.
Apparatus for forming the leads of electrical components, the apparatus comprising:
- a reel of tape having a plurality of electrical components adhered thereto, the tape having a section extending to a retro-reflective sensor adapted to detect the presence of an electrical component contained on the tape;
- a motor drivingly connected to the reel;
- a paddle engaged with the section and movable as slack in the section varies, the paddle activating the motor upon moving to a predetermined position;
- a cutter for singulating a segment of tape having at least one electrical component from the remainder of the tape after the sensor detects the presence of an electrical component;
- a pneumatically operated die set adapted to accept the segment of tape and to form the leads of the electrical component contained on the segment into a desired configuration;
- and
- a gauge plate adapted to accept the electrical component from the die set and to verify the configuration of the leads.
Apparatus for forming the leads of electrical components contained on a tape, the apparatus comprising:
- a sensor for detecting the presence of an electrical component contained on the tape;
- means for singulating a segment of tape having at least one electrical component from the remainder of the tape after the sensor detects the presence of an electrical component;
- a lead forming station adapted to accept the segment of tape and to form the leads of the electrical component contained on the segment into a desired configuration;
- an inspection station adapted to accept the electrical component from the lead forming station and to verify the configuration of the leads, the inspection station comprising a plate having a hole pattern matching the desired configuration of the electrical component leads.
