Abstract
Abstract A chip mounter for automatically mounting an electronic part onto a substrate. The chip mounter has a sucker for vacuum-holding the electronic part, at least one pair of fingers capable of reciprocatively moving between an electronic part clamping position and a release position and of also moving vertically, and a guide for guiding the fingers so that they perform linear reciprocative movement. Positioners for clamping the electronic part are disposed on the respective distal ends of the fingers in such a manner that their positions are adjustable in the clamping direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
A chip mounter comprising: a vertically movable sucker capable of suction-holding a chip; a pair of fingers positioned in the vicinity of said sucker and horizontally movable reciprocatively between a first position where said fingers clamp a chip and a second position where said fingers release said chip; guide means for linearly, reciprocatively guiding said fingers, said guide means having; a support member, a plurality of vertically movable guide plates connected to said support member with a predetermined spacing provided between each pair of adjacent guide plates, and a horizontally extending slide groove in each guide plate; and, a pair of rollers supported by said fingers in sliding contact with said guide plate grooves, whereby said fingers are horizontally movable through engagement of said rollers with said slide grooves while being guided by the space between said guide plates.
Claim 2
Dependent Claim
139 words
A chip mounter comprising: a vertically movable sucker capable of suction-holding a chip; a pair of fingers positioned in the vicinity of said sucker and horizontally movable reciprocatively between a first position where said fingers clamp a chip and a second position where said fingers release said chip; guide means for linearly, reciprocatively guiding said fingers, said guide means having; a support member, a plurality of vertically movable guide plates connected to said support member with a predetermined spacing provided between each pair of adjacent guide plates, and a horizontally extending slide groove in each guide plate; and, a pair of rollers supported by said fingers in sliding contact with said guide plate grooves, whereby said fingers are horizontally movable through engagement of said rollers with said slide grooves while being guided by the space between said guide plates.
Claim 3
Dependent Claim
36 words
A chip mounter according to claim 1, wherein said fingers are provided so as to extend in the shape of a cross whose center is defined by the axis of a sucker tube of said sucker.
Claim 4
Dependent Claim
41 words
A chip mounter according to claim 1, wherein each of said fingers has a positioner for clamping said chip secured to its distal end in such a manner that the position of said positioner is adjustable in the chip clamping direction.
Claim 5
Dependent Claim
68 words
A chip mounter according to claim 1, wherein said fingers are biased inward through two pairs of push levers which are in turn, biased by a biasing spring wound on said support member, and said fingers, which are in opposing relation to each other, are horizontally movable by equal distances by the action of a pair of equalizers pivotally supported between said two pairs of push levers, respectively.
Claim 6
Dependent Claim
43 words
A chip mounter according to claim 1, wherein the vertical movement of a sucker tube of said sucker and the horizontal reciprocative movement of said fingers between said chip clamping and said chip releasing positions are effected in interlocking relation to each other.
