Abstract

An electronic component conveyance device in which an electronic component is unlikely to jam in a conveyance path. A first magnetic force generation unit is provided lateral to a first sidewall in a midstream part. An interval between the first sidewall and a second sidewall in the midstream part is larger than an interval between the first sidewall and the second sidewall in an upstream part and an interval between the first sidewall and the second sidewall in a downstream part. The first sidewall is flat across the upstream part, the midstream part, and the downstream part.

First claim

What is claimed is:

1. An electronic component conveyance device comprising:
a conveyance path; and
a first magnetic force generation unit,
the conveyance path including an upstream part, a midstream part connected with the upstream part, and a downstream part connected with the midstream part,
the conveyance path including a bottom face, a first sidewall, and a second sidewall defining the upstream part, the midstream part, and the downstream part,
the first sidewall and the second sidewall facing each other at an interval,
the first magnetic force generation unit being provided lateral to the first sidewall in the midstream part,
an interval between the first sidewall and the second sidewall in the midstream part being larger than an interval between the first sidewall and the second sidewall in the upstream part and larger than an interval between the first sidewall and the second sidewall in the downstream part, and
the first sidewall being continuously flat across the upstream part, the midstream part, and the downstream part,
wherein the first magnetic generation unit applies magnetic force to a rectangular parallelepiped electronic component including a plurality of stacked internal conductors so that the electronic component can rotate about an axis extending in a length direction of the electronic component.

2. The electronic component conveyance device according to claim 1 , wherein
the midstream part includes a transition part connected with the downstream part, and
in the transition part, the second sidewall is tilted with respect to a conveyance direction and an interval between the first sidewall and the second sidewall is smaller at a position closer to the downstream part.

3. The electronic component conveyance device according claim 1 , further comprising a second magnetic force generation unit provided lateral to the second sidewall in the midstream part and arranged at a farther downstream side than the first magnetic force generation unit,
wherein magnetic force generated by the second magnetic force generation unit is weaker than magnetic force generated by the first magnetic force generation unit.

4. The electronic component conveyance device according to claim 1 , further comprising a second magnetic force generation unit provided lateral to the second sidewall in the midstream part and arranged at a farther downstream side than the first magnetic force generation unit,
wherein the first magnetic force generation unit does not overlap with other magnetic force generation units including the second magnetic force generation unit in a width direction orthogonal to a conveyance direction, and
the second magnetic force generation unit does not overlap with other magnetic force generation units including the first magnetic force generation unit.

5. The electronic component conveyance device according to claim 1 , wherein the first magnetic force generation unit includes one of a permanent magnet and an electromagnet.

6. The electronic component conveyance device according to claim 1 , wherein the conveyance path conveys the electronic component in the length direction of the electronic component.
