Inner surface of the bladeholder receiving portion 43 is formed withengagement surfaces slant surfaces blade holder 21A. Owing to the fact that the slant surfaces 21C and 21C are placed on theseengagement surfaces cutter blade 21 in the receivingsection 41 is managed to be at a constant position. Note that, when the slant surfaces 21C and 21C are formed asymmetrically, the engagement surfaces 43A and 43A are formed in an asymmetry shape respectively corresponding to the slant surfaces 21C and 21C. Through forming the slant surfaces 21C and 21C asymmetrically as described above, thecutter blade 21 is received and stored only in a predetermined direction. Accordingly, storing failure of thecutter blade 21 can be prevented. - In the receiving
sections 41 of thestock device 11, the two at the left side inFIG. 4 are heatingstorage sections 41A; and the two at the right side are washingstorage sections 41B. Theheating storage sections 41A are provided withcoil heaters 45 constituting heating means at the peripheral side thereof, and is arranged so that, when power is supplied to thecoil heaters 45, heat is generated and heats up thecutter blade 21. On the other hand, in thewashing storage sections 41B, theblade receiving portion 44 is formed to be a common space. In theblade receiving portion 44, organic solvent L as washing liquid, which constitutes the washing means, is contained, and is arranged so as to dissolve and remove the adhesive and the like adhered on theblade 21B with the organic solvent L. Note that thewashing storage section 41B is arranged so as to ensure constantly a space for washing theblade 21B of thecutter blade 21 after thecutter blade 21 is repeatedly and continuously used for sheet cutting operation. - Next, the working of the embodiment will be described.
- After the sheet S is stuck on the wafer W supported on the table 13 as shown in
FIG. 2 , thecutter blade 21 on thecutting device 10 moves along the outer periphery of the wafer W to cut the sheet S at the outside of the wafer W as an unnecessary sheet portion. - When the sheet cutting operation is carried out repeatedly and continuously, it is conceivable that adhesive is transferred from sheets S onto the
cutter blade 21 which has been used for cutting. Therefore, thecutter blade 21 is stored in a vacant space of thewashing storage section 41B in thestock device 11, and the adhesive is dissolved and removed with the organic solvent L in thewashing storage section 41. Thecutter blade 21 is stored in a state that the slant surfaces 21C of theblade holder 21A match with the engagement surfaces 43A. Owing to this, thecutter blade 21 is kept in the constant direction. On the other hand, thecutter blade 21, which has been washed for a specific period of time, is transferred to theheating storage section 41A while keeping the same orientation by the cuttingdevice 10, and is subjected to the heating process by thecoil heaters 45. - In the next cutting operation, the cutting
device 10 moves to pick up thecutter blade 21, which has been heated, and while keeping the constant orientation, acutter blade 21 is mounted onto the cutterblade holding chuck 29 in a state that the orientation corresponding to the above-described traveling track can be maintained. - Therefore, according to the embodiment as described above,
such stock device 11 can be provided that thecutter blade 21 can be mounted automatically in the constant orientation with respect to the cutter blade holding chuck of the cuttingdevice 10, and if necessary, theheated cutter blade 21 can be used, and adhesive or the like adhered on thecutter blade 21 can be dissolved to prevent the cutting accuracy of theblade 21B from being deteriorated. - The best arrangement and method for carrying out the present invention have been disclosed so far. However, the present invention is not limited to the above.
- That is, the present invention has been illustrated and described mainly about a specific embodiment. However, it is possible for those skilled in the art to add various modifications, if necessary, to the above-described embodiment with respect to the shape, position and/or disposition without departing from the technical spirit and the range of the object of the present invention.
- For example, as for the washing means, it is not limited to the use of organic solvent L. As shown in
FIG. 5 , such an arrangement may be adopted that arotation brush 50 is disposed as the washing means within theblade receiving portion 44, and theblade 21B is washed by therotation brush 50. In this case, if necessary, theblade receiving portion 44 may be arranged to be filled with washing liquid. - Also, as shown in
FIG. 6 , such an arrangement may be adopted that theblade receiving portion 44 is equipped with inspection means 60 constituted of a camera or the like capable of inspecting the surface of theblade 21B to inspect defects and the like on theblade 21B. - Although the organic solvent L is used to dissolve the adhesive and the like adhered on the
blade 21B in the above-described embodiment, such an arrangement may be adopted that theblade 21B is washed with an ultrasonic vibrating device using water or the like as the washing liquid.
