Inspection device of a tape reel

Abstract

An inspection device of a tape reel comprises a first inspection device 10 consisting of a light projector 11, a mirror 12, and a light receiver 13, a second inspection device 20 consisting of a light projector 21, a mirror 22, and a light receiver 23, and a rotator 30 that rotates a tape reel 40, and parallel lights R 1, R 2 irradiated from the light projector 11 are reflected by the mirror 12, to be made incident on inner surfaces of flanges 42, 43 of the tape reel 40, whereas parallel lights R 3, R 4 irradiated from the light projector 21 are reflected by the mirror 22 to be made incident on the inner surfaces of the flanges 42, 43 of the tape reel 40, and parallel lights R 1 to R 4 that pass the inner surfaces of the flanges 42, 43 are received by the light receiver 13 or the light receiver 23. Thereby, an inspection device capable of inspecting a position of each flange of the tape reel, distance between flanges, and an inclined angle of each flange in a un-contact state accurately at high speed, an inspection method for the same, and a positioning device of a member to be positioned capable of positioning the position of the flange accurately are provided.

1 . A positioning device of a member to be positioned, comprising 
 a table that has a member to be positioned serving as a hub as described in  claim 1  placed thereon;    a guide pin which is erected on the placement surface and positions the member to be positioned on the table by fitting its positioning hole thereinto;    pluralities of injection pores that open on the outer periphery surface of the guide pin;    an internal passage which is formed in the guide pin so as to inject a predetermined pressure of fluid from each injection pore toward the inner peripheral surface of the positioning hole of the member to be positioned; and    a fluid supply device which is connected to the other end of the internal passage and supplies a predetermined pressure of fluid thereto, so that the member to be positioned may be moved to an aligning position centering on the guide pin by pressure of the fluid injected from each injection hole.    
     
     
         2 . The positioning device of the member to be positioned as described in  claim 1 , wherein the table is supported by an elastic body in an elevating/lowering manner, and a lid that is lowered to the table from the upper part of the table is formed in an elevating/lowering manner, so that a gap partitioned by the inner peripheral surface of the positioning hole, the outer peripheral surface of the guide pin, and the placement surface of the table may be closed by the lid.  
     
     
         3 . The positioning device of the member to be positioned as described in  claim 2 , wherein a negative pressure suction port that absorbs the member to be positioned, opens on the placement surface of the member to be positioned serving as a hub, and after positioning the member to be positioned, the negative suction pressure is generated in the negative pressure suction port, to thereby absorb the member to be positioned onto the table.
