Abstract
In an electronic chip supplying apparatus, a vacuum suction device for sucking a retainer tape which encases electronic chips is provided in a retainer tape support member provided at an opening position where the electronic chips are picked up from a chip pickup device, or a tension applying device for the retainer is provided. Thus, vertical fluctuation of the retainer tape is prevented at the opening position.
Claims6
An electronic chip supplying apparatus comprising:
- guide means for guiding a retainer tape to an opening position where electronic chips are to be picked up by a chip pickup means, said electronic chips being encased in recesses arranged along a longitudinal direction of said retainer tape, and said recesses being sealed by attaching a detachable coating tape onto a top surface of said retainer tape;
- intermittent driving means for intermittently pulling under traction said retainer tape at a position downstream of said opening position;
- peeling means for peeling said coating tape away from said retainer tape at said opening position;
- tape support means for supporting said retainer tape at said opening position including vacant chamber means maintained undera vacuum pressure, an aperture means communicating with said vacant chamber means and opening toward said retainer tape;
- and
- suppressing means for suppressing vertical fluctuation of said retainer tape at said opening position, said suppressing means includes said tape support means.
An electronic chip supplying apparatus comprising:
- guide means for guiding a retainer tape, which encases electronic chips, to an opening position where a chip pickup means is located;
- intermittent driving means for intermittently pulling under traction said retainer tape;
- peeling means for peeling a coating tape away from the retainer tape at said opening position;
- and
- tape support means for supporting said retainer tape at said opening position;
- said tape support means including a vacant chamber means maintained under vacuum pressure, and aperture means communicating with the vacant chamber means and opening toward said retainer tape.
An electronic chip supplying apparatus comprising:
- guide means for guiding a retainer tape which encases electronic chips;
- means for moving said retainer tape;
- means for peeling a coating tape away from said retainer tape;
- and
- tape support means for supporting said retainer tape at an opening position where a chip pickup means is located, said tape support means including a vacant chamber means maintained under vacuum pressure, and aperture means communicating with the vacant chamber means and opening towards said retainer tape.
A retainer tape support member for supporting a retainer tape that encases therein electronic chips at an opening position where a chip pickup means of an electronic chip supplying apparatus is located, the retainer tape support member comprising:
- a vacant chamber means maintained under vacuum pressure;
- and
- aperture means communicating with the vacant chamber means and opening toward a retainer tape means so as to apply a vacuum pressure on the retainer tape.
An electronic chip supplying method comprising the following steps of:
- intermittently moving a retainer tape, which encases therein electronic chips, to a chip pickup position;
- sucking said retainer tape at said chip pickup position toward a tape support means, said sucking step being performed simultaneously with said intermittently moving step;
- peeling a coating tape from said retainer tape at said chip pickup position;
- and
- after said peeling step, picking up said chips away from said retainer step.
