Abstract

Selon la présente invention, cette unité de tête comprend un corps rotatif dans lequel une pluralité d'outils de maintien de composant aptes à maintenir des composants sont disposés à des intervalles égaux le long d'une circonférence prescrite, et l'unité de tête amène la pluralité d'outils de maintien de composant à tourner en amenant le corps rotatif à tourner. L'unité de tête comprend : un dispositif de levage/d'abaissement permettant de lever et d'abaisser un outil de maintien de composant, parmi la pluralité d'outils de maintien de composant, qui est positionné à une position de levage/d'abaissement prescrite sur l'unité de tête, le dispositif de levage/d'abaissement étant disposé indépendamment du corps rotatif ; et un élément de support d'outil de maintien de composant servant à permettre une opération par le dispositif de levage/d'abaissement pour lever/abaisser l'outil de maintien de composant positionné au niveau de la position de levage/d'abaissement, l'élément de support d'outil de maintien de composant étant disposé sur le côté interne de la circonférence de façon à éviter la rotation en accompagnement du corps rotatif, et étant apte à tenir, à une position de hauteur prescrite, les outils de maintien de composant parmi la pluralité d'outils de maintien de composant autres que l'outil de maintien de composant positionné au niveau de la position de levage/d'abaissement.
