Abstract

The present disclosure relates to a cutting apparatus including a jig having a seating jig on which a machining target is seated and a fixing jig matched with the seating jig to fix the machining target, a cutter configured to cut the machining target along reference scheduled cutting lines, a first carrier reciprocating to allow the fixing jig to match with the seating jig or to be spaced apart from the seating jig, and a cooler configured to cool the machining target down to a reference temperature.

First claim

What is claimed is:

1. A cutting apparatus comprising:
a jig unit having a seating jig on which a machining target is seated and a fixing jig matched with the seating jig to fix the machining target;
a first cutter configured to cut the machining target along first scheduled cutting lines of the machining target;
a first carrier configured to reciprocate to allow the fixing jig to match with the seating jig; and
a cooler configured to cool the machining target down to a reference temperature,
wherein the first carrier includes:
a mounting plate on which the fixing jig and the first cutter are mounted; and
a transfer cylinder configured to reciprocate to allow the mounting plate to approach the machining target or to be spaced apart from the machining target, and

wherein the transfer cylinder is configured to position the mounting plate in a fixing position where the fixing jig is in contact with the machining target while the first cutter is spaced apart from and thus is not in contact with the machining target in order to fix the machining target during cooling of the cooler without cutting the machining target.

2. The cutting apparatus of claim 1 , wherein the fixing jig selectively presses a reference pressed area of the machining target such that the first scheduled cutting lines are exposed to an outside of the jig unit.

3. The cutting apparatus of claim 1 , wherein the first carrier further includes:
elastic members connecting the jig unit and the mounting plate, the elastic members elastically extending and contracting in a reciprocation direction of the fixing jig.

4. The cutting apparatus of claim 3 , wherein the elastic members have a reference length such that the first cutters reach the first scheduled cutting lines after the fixing jig reaches the pressed area.

5. The cutting apparatus of claim 3 , wherein the elastic members include compression coil springs elastically extending and contracting in the reciprocation direction of the fixing jig.

6. The cutting apparatus of claim 1 , further comprising: a second cutter configured to cut the machining target along reference second scheduled cutting lines,
wherein the seating jig includes:
a first seating jig on which a portion of the machining target is seated; and
a second seating jig on which another portion of the machining target is seated,
wherein the first seating jig and the second seating jig are spaced apart from each other by a reference interval such that the second scheduled cutting lines of the machining target are exposed to an outside of the jig unit through a space between the first seating jig and the second seating jig.

7. The cutting apparatus of claim 6 , further comprising:
a second carrier reciprocating to allow the second cutter to approach the machining target or to be spaced apart from the machining target, through the space between the first seating jig and the second seating jig.

8. The cutting apparatus of claim 6 , wherein the cooler includes:
a blower fan configured to blow air to the machining target through the space between the first seating jig and the second seating jig.

9. The cutting apparatus of claim 1 , wherein the cooler cools at least one of the seating jig and the fixing jig to indirectly cool the machining target.

10. The cutting apparatus of claim 9 , wherein the cooler includes:
a blower fan configured to blow air to at least one of the seating jig and the fixing jig.

11. The cutting apparatus of claim 1 , wherein the cooler has a cooling water passage formed in at least one of the seating jig and the fixing jig such that externally supplied cooling water flows through the cooling water passage.

12. The cutting apparatus of claim 1 , wherein the first carrier reciprocates to allow the fixing jig to be spaced apart from the seating jig.
