Abstract
Abstract An apparatus for assembling the component parts of a cover for an electrochemical cell into a cover assembly and for welding the assembly, the apparatus including a carousel having a plurality of equally spaced receptacles, an equal number of equally spaced stations around the carousel, a drive for intermittently turning the carousel to advance the receptacles to each of the stations and holding the receptacle in the station, a feeder at selected stations for feeding a part of the component parts to the carousel, inspection apparatus at stations intermediate the selected stations for inspecting the part assembly in the receptacle, a welder at a station following the selected and inspection stations for welding the assembled cover in the receptacle and an extractor at a station following the welding station for removing the assembled and welded cover from the receptacle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
216 words
An apparatus for assembling and welding into a composite unit the component parts of a vented cover for electrochemical cells, said apparatus including a carousel, receptacles fixed on said carousel, and stations around said carousel; means at respective ones of said stations for feeding to said receptacles the component parts of a cover to be assembled, one of said stations including means for forming a spring coil from wire fed to said station; said coil forming means comprising; a coiling post; means for retracting said coiling post upon the conclusion of a winding of a spring coil; a chute disposed beneath said post and extending upwardly toward the site of said spring coil for contacting a base of said coil upon a retracting of said post, said coil dropping into said chute upon said retraction of said post; said chute being curved for reorienting said coil from a horizontal orientation to a vertical orientation upon a feeding of said coil to said receptacle; and wherein said apparatus further comprises a vacuum operated nozzle having an interior surface configured for mating with said spring coil, said coil being lifted from a receptacle and depositioned within a cover member by activation and release of vacuum; and means at a following station for welding the assembled component cover parts.
Claim 2
Independent Claim
216 words
An apparatus for assembling and welding into a composite unit the component parts of a vented cover for electrochemical cells, said apparatus including a carousel, receptacles fixed on said carousel, and stations around said carousel; means at respective ones of said stations for feeding to said receptacles the component parts of a cover to be assembled, one of said stations including means for forming a spring coil from wire fed to said station; said coil forming means comprising; a coiling post; means for retracting said coiling post upon the conclusion of a winding of a spring coil; a chute disposed beneath said post and extending upwardly toward the site of said spring coil for contacting a base of said coil upon a retracting of said post, said coil dropping into said chute upon said retraction of said post; said chute being curved for reorienting said coil from a horizontal orientation to a vertical orientation upon a feeding of said coil to said receptacle; and wherein said apparatus further comprises a vacuum operated nozzle having an interior surface configured for mating with said spring coil, said coil being lifted from a receptacle and depositioned within a cover member by activation and release of vacuum; and means at a following station for welding the assembled component cover parts.
Claim 3
Dependent Claim
35 words
An apparatus, as recited in claim 1, in which said feeding means further includes a component-part chute and vibrating-centrifugal hopper means for sorting and feeding component parts, one after the other, to said component-part chute.
Claim 4
Dependent Claim
50 words
An apparatus, as recited in claim 1, in which said welding station includes welding heads and means for advancing said welding heads into engagement with the assembled component cover parts in the receptacle at said welding station and for retracting said heads from said receptacle after said parts are welded.
Claim 5
Dependent Claim
24 words
An apparatus, as recited in claim 1, in which said coil forming means includes a stripper for stripping the formed coil from said post.
Claim 6
Dependent Claim
50 words
An apparatus, as recited in claim 4, in which said welding station includes welding heads and means for advancing said welding heads into engagement with the assembled component cover parts in the receptacle at said welding station and for retracting said heads from said receptacle after said parts are welded.
