Abstract
Abstract A system for arranging chips in series in a tape capable of automatically and efficiently carrying out all steps from the feeding of chips to the arranging of them in series in recesses of a tape with high reliability. The system includes a chip feed section adapted to individually separate chips and automatically eliminate a chip defective in configuration while supplying chips, a first intermittently turned index table formed with chip receiving grooves for successively receiving chips one by one from the chip feed section and adapted to automatically eliminate a chip defective in electrical characteristics, and a chip transferring section for transferring chips from the first index table to a second intermittently turned index table. The second index table is formed with chip receiving grooves for successively receiving chips one by one from the chip transferring section. Chips are then taken out and arranged in recesses of an intermittently moving tape one by one by a suction pin. Around the first index table are arranged a chip measuring section for measuring electrical characteristics of a chip and a chip marking section for putting a mark or a value of measured electrical characteristics on a chip.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
156 words
A system for arranging chips in series comprising: a first index table of a disc-like shape intermittently turned and formed with chip receiving grooves at equal intervals; a chip feed section for supplying chips one by one to said first index table; a chip measuring and marking mechanism for measuring electrical characteristics of each of the chips successively carried by said first index table and putting a mark on a chip measured; a second index table of a disc-like shape intermittently turned and formed with chip receiving grooves at equal intervals; chip transferring means arranged between said first index table and said second index table for successively transferring normal chips delivered from said first index table to said second index table; and a chip arranging section provided in proximity to said second index table to successively take out chips from said second index table and arrange the chips in series in a tape by vacuum suction.
Claim 2
Independent Claim
156 words
A system for arranging chips in series comprising: a first index table of a disc-like shape intermittently turned and formed with chip receiving grooves at equal intervals; a chip feed section for supplying chips one by one to said first index table; a chip measuring and marking mechanism for measuring electrical characteristics of each of the chips successively carried by said first index table and putting a mark on a chip measured; a second index table of a disc-like shape intermittently turned and formed with chip receiving grooves at equal intervals; chip transferring means arranged between said first index table and said second index table for successively transferring normal chips delivered from said first index table to said second index table; and a chip arranging section provided in proximity to said second index table to successively take out chips from said second index table and arrange the chips in series in a tape by vacuum suction.
Claim 3
Dependent Claim
19 words
A system as defined in claim 1 further comprising mark drying means intermediately arranged at said chip carrying means.
Claim 4
Dependent Claim
35 words
A system as defined in claim 1, wherein said chip feed section includes a chip separating mechanism for individually separating chips and detecting a chip defective in configuration and means for removing said defective chip.
Claim 5
Dependent Claim
52 words
A system as defined in claim 1, wherein said first index table includes defective chip eliminating means for eliminating a chip defective in electrical characteristics detected at said chip measuring and marking mechanism, said defective chip eliminating means being arranged at a position which is not associated with said chip transferring means.
Claim 6
Dependent Claim
141 words
A system as defined in claim 1, wherein said chip feed section comprises a linear feeder formed with an aligning groove for arranging a plurality of chips delivered from a chip source in a row; a separation slider formed with a separation groove which is connected to said aligning groove of said linear feeder when said separation slider is in a state capable of accepting a chip; an insertion guide formed with a guide groove which is connected to said separation groove when said separation slider is in a state capable of separating chips; a pusher for pushing out a chip received in said separation groove to said guide groove; and suction means for removing a chip defective in configuration by suction when said chip defective in configuration is in said separation groove to interfere with movement of said separation slider.
Claim 7
Dependent Claim
15 words
A system as defined in claim 5, wherein said suction means comprises a suction pin.
Claim 8
Dependent Claim
31 words
A system as defined in claim 5, wherein said linear feeder includes an air jet nozzle for blowing air against chips arranged in said aligning groove in a chip advancing direction.
Claim 9
Dependent Claim
135 words
A system as defined in claim 1, wherein said chip measuring and marking mechanism comprises a chip measuring section for measuring electrical characteristics of each of the chips carried by said first index table and a chip marking section for putting a mark on a chip measured at said chip measuring section; said chip measuring section and chip marking section being arranged around said first index table; said first index table including a plurality of push rods slidably arranged on said first index table so as to be slidable in a radial direction of said first index table, so that a chip defective in electrical characteristics detected at said chip measuring section may be eliminated by actuation of each of said push rods at a position which is not associated with said chip transferring means.
Claim 10
Dependent Claim
