Abstract

(57) [Abstract] [Purpose] Electronic component supply capable of continuously performing variable insertion pitch insertion of at least twice the bending length of the lead wire within the insertable pitch range of the electronic component insertion machine. Provide a device. [Structure] Wheels 52 and 53 intermittently rotate in the same direction for one pitch to supply leaded electronic component 51A to supply position 54. The supplied electronic component with lead 51A is formed by cutting the lead wire with the movable blade 56 and the fixed blade 57, and lowering the insertion guide 58. At the same time, the tape cutter movable blades 61 and 62 and the tape cutter fixed blades 63 and 64 connect the electronic components with leads.
Cut the tape at 51. The cut tape waste is discharged by the tape waste suction devices 65 and 66. Therefore, since there is no lead waste after supply, the receiving lever does not interfere even if the insertion pitch is changed, so that the insertion pitch can be continuously changed twice or more the bending length of the lead wire within the insertable pitch range. It can be carried out.
