Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
207 words
An apparatus for application of glue in preselected zones of a printed circuit board, said apparatus comprising a mounting frame, a glue tank positioned on said frame, a plurality of push rods, carrier means for carrying said push rods in substantially parallel relationship and arranged at predetermined positions, support means carried by said frame for removably supporting and positioning a printed circuit board above said glue tank, said carrier means movable toward and away from said tank so that the ends of the push rods contact the glue in said tank and are provided with a glue drop that can be deposited on a printed circuit board supported on said support means to form thereon a plurality of glue drops, and means for limiting the movement of said carrier means toward said support means, said movement limiting means including centering gudgeon means carried by said carrier means and engageable in holes in said support means for laterally positioning said carrier means relative to said support means, said gudgeon means including limit means for limiting the extent of engagement of said gudgeon means with said support means so that only the glue drops contact the printed circuit board and the ends of said push rods are spaced therefrom.
Claim 2
Independent Claim
207 words
An apparatus for application of glue in preselected zones of a printed circuit board, said apparatus comprising a mounting frame, a glue tank positioned on said frame, a plurality of push rods, carrier means for carrying said push rods in substantially parallel relationship and arranged at predetermined positions, support means carried by said frame for removably supporting and positioning a printed circuit board above said glue tank, said carrier means movable toward and away from said tank so that the ends of the push rods contact the glue in said tank and are provided with a glue drop that can be deposited on a printed circuit board supported on said support means to form thereon a plurality of glue drops, and means for limiting the movement of said carrier means toward said support means, said movement limiting means including centering gudgeon means carried by said carrier means and engageable in holes in said support means for laterally positioning said carrier means relative to said support means, said gudgeon means including limit means for limiting the extent of engagement of said gudgeon means with said support means so that only the glue drops contact the printed circuit board and the ends of said push rods are spaced therefrom.
Claim 3
Dependent Claim
29 words
An apparatus according to claim 1, wherein said carrier means is provided with resilient means allowing a resilient retraction of at least part thereof relative to said glue tank.
Claim 4
Dependent Claim
25 words
An apparatus according to claim 1, wherein said frame includes means to position said support means in a plane substantially parallel to said glue tank.
Claim 5
Dependent Claim
19 words
An apparatus according to claim 1, wherein said push rods have a cylindrical end at the dipping zone thereof.
Claim 6
Dependent Claim
28 words
An apparatus according to claim 1, wherein the glue tank is provided with scraper means to level the glue after refilling so that the glue height is unchanged.
