Description

Pin acquisition device and pin acquisition method Technical Field The present invention relates to a pin acquisition device and a pin acquisition method, and more particularly, to a pin acquisition device and a pin acquisition method capable of acquiring a part of pins from a plurality of supplied pins. Background Conventionally, from a state where a plurality of pins are accommodated in a cylindrical case, an operator directly takes out the pins from the case to a table or a work table on a plane, disperses the pins on the work table, and takes out the pins by manually gripping the pins from the plurality of pins dispersed on the work table with tweezers or the like. The size of the target pin is small, for example, about 30 μm in diameter and about 10mm to 20mm in total length, and the pin is small and requires a fine work at the time of handling, so that a work error is liable to occur, and the skill of the operator is required. Patent document 1 discloses a pin feeder in which flanged pins are arranged and inserted (fed) one by one to a predetermined position. According to patent document 1, the micro pin supply device includes a vibration chute for arranging micro pins in a hopper, a swing arm including a protrusion having a suction port for sucking and catching the micro pins, which is disposed in contact with the front end of the vibration chute, and which moves backward and swings by a shuttle table, and a shutter interposed between the forefront end of the vibration chute and the second micro pin, wherein the protrusion of the swing arm functions as a stopper to stop the micro pin moving forward by the vibration chute, and the sucked micro pin is moved to a delivery position by separating the shutter from the second micro pin after the micro pin is caught by the suction port of the protrusion. Thus, the minute pins can be supplied to the predetermined positions one by one. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. Hei 04-45013 Disclosure of Invention Problems to be solved by the invention Conventionally, only 1 pin out of many pins having small shapes is manually removed. Since the pin is small and requires a delicate work when handling, a work error due to a manual work is easily caused, and a high degree of skill of the operator is required. Further, it is conceivable that the pin handled by the minute pin supply device disclosed in patent document 1 has a size of about 0.4mm in diameter and is further a flanged pin, and therefore it is difficult to use the minute pin supply device for a pin having a diameter of about 30 μm and having no flange. Under such circumstances, the present inventors have repeatedly studied and tested in order to solve the above-mentioned problems, and as a result, have conceived the present invention in which, conventionally, the operation of taking out only one pin from a plurality of pins having a small shape is performed manually, but when the pins are obtained in order to solve the above-mentioned state, when the pins are obtained, a part of the pins are lifted from the plurality of pins by vibration, the lifted pins are restrained from being sucked and fixed in the axial direction, the pins have an internal space for holding the plurality of pins to be sucked and fixed in a raised state, and a single pin is discharged through an insertion hole provided in the bottom surface of the internal space and having a diameter through which only one pin can pass, whereby the number of pins is reduced stepwise from the supply of the plurality of pins, and the single pin can be taken out in a raised state. Accordingly, an object of the present invention is to provide a pin acquisition device and a pin acquisition method, in which, when pins are acquired, a part of the pins are lifted from a plurality of pins by vibration, the lifted pins are sucked and fixed, the number of the pins is reduced stepwise, and the pins can be acquired stably, and further, the individual pins can be taken out in a standing state. Technical means for solving the problems In order to achieve the above object, the pin acquisition device according to the present invention acquires a part of pins from a plurality of pins, and is characterized by comprising a pin placement portion configured in a groove shape capable of restricting the axial direction of the plurality of pins placed inside to coincide with the groove direction, a first vibration application portion capable of vibrating the pin placement portion so that at least a part of the plurality of pins can jump up in the interior of the pin placement portion, an adsorption arm sucking and adsorbing a plurality of pins among the pins that have risen up via the web portions of the plurality of pins, a bottle portion having an internal space for holding the plurality of pins that are adsorbed and fixed to the adsorption arm and for holding the plurality of pins in a standing state, the bottle portion capab
