Component supplying unit

Abstract

The invention provides a double-line feeder type component supplying unit, wherein chain wheels of an intermittent delivery storage belt are installed under a stable state, so that component adsorption positions of electronic components are stabilized. Around a supporting shaft (39), casing pipes (43A,43B) are covered on a position of a clamping restriction portion (39E). Then, ball bearings (40A1,40A2) are covered around the supporting shaft (39) in a way of using extrusion convex portions (40A131,40A231)to clamp a spur gear (37) on a side, and ball bearings (40A3,40A4) are covered around the supporting shaft (39) in a way of using extrusion convex portions (40A331,40A431)to clamp a spur gear (37) on the other side. Under such state, set screws (43,44) are firmly fastened in a way that an embedding portion (21C) of a unit frame (21) is embedded in an embedding hole (39A) of the supporting shaft (39).

Description

technical field [0001] The present invention relates to a dual-line feeder type component supply unit capable of independently supplying electronic components in parallel from two storage belts through two conveying mechanisms. Background technique [0002] For example, as disclosed in Patent Document 1 and the like, a component supply unit that supplies electronic components intermittently conveys storage tapes that are drawn out sequentially to a component take-out position. In addition, a plurality of the above-mentioned component supply units are provided in parallel in the electronic component mounting apparatus, but as the component supply unit, a two-line feeder type component supply unit that can supply electronic components in parallel using two storage belts is used. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-67933 [0004] However, the conveying teeth formed on the outer circumference mesh with the conveying holes formed in the st...
