This creation provides a kind of needle base positioning device, including a conveying mechanism and a guide mechanism. The conveying mechanism is equipped with and one sets needle stand, this, which is set needle stand and is formed with plural number, plugs portion； The guide mechanism is put for plural needle base, and respectively the needle base is formed with a jack； Wherein the conveying mechanism can drive this to set needle stand mobile relative to the what guide mechanism, it is inserted into the respectively jack of the needle base with allowing this to set respectively portion of plugging of needle stand, make respectively this plug portion and be fixed to each other with the respectively needle base, the respectively needle base is set needle stand with this and moves to a predeterminated position person in order to benefit. Thereby, needle stand is set through this respectively the needle base plugs fixation to what, multiple needle bases can be taken out and be moved to the assembling operation that Hou continues with needle stand is set simultaneously, can improve the packaging efficiency of injection needle apparatus.本創作提供一種針基定位裝置，包括一輸送機構及一導引機構。該輸送機構設有一置針座，該置針座形成有複數插設部；該導引機構供複數針基置放，各該針基形成有一插孔；其中該輸送機構能驅使該置針座相對於該導引機構移動，以讓該置針座之各該插設部插入各該針基之插孔內，使各該插設部與各該針基相互固定，俾利將各該針基隨該置針座而移至一預設位置者。藉此，透過該置針座對於各該針基之插設固定，即能同時將多個針基隨置針座取出並移至後續之組裝作業，以能提高注射針具之組裝效率。
