Inspection device for cooling plate
Proposed is an inspection device for a cooling plate capable of accurately inspecting cooling plates to reduce cooling plate defect rate. The device includes an inspection table including a base on which a cooling plate is seated, a support block located on each side of the cooling plate, a guide block, and a plurality of height blocks supporting a lower surface of a base plate, a clamp provided on the base and pressing an upper surface of the base plate, a plurality of gauge jigs and a plurality of gauge grooves, a first measurement unit measuring a distance at which the end of an extension plate is spaced from a bending plate, and a second measurement unit measuring a distance at which the end of the bending plate is spaced apart from the end of the base plate in the width direction, and measuring the flatness of the base plate.
1 . An inspection device for a cooling plate having a base plate, a bending plate bent to a first side at each end of the base plate in a width direction, and an extension plate extending from an end of the bending plate toward a second side and outward of the base plate, the inspection device comprising:
an inspection table comprising:
a base on which the cooling plate is seated;
a support block located on each side of the cooling plate seated on the base in the width direction and provided along a length of the cooling plate;
a guide block provided on the support block and in close contact with an end of the extension plate; and
a plurality of height blocks provided on the base and supporting a lower surface of the base plate;
a clamp provided on the base and pressing an upper surface of the base plate;
a plurality of gauge jigs provided on the support block along a length of the support block; and a plurality of gauge grooves;
a first measurement unit coupled to each of the gauge jigs to measure a distance at which the end of the extension plate is spaced from the bending plate; and
a second measurement unit seated on the support block to measure a distance at which the end of the bending plate is spaced apart from the end of the base plate in the width direction, and is coupled to each of the gauge grooves to measure a flatness of the base plate.
2 . The inspection device of claim 1 , wherein the first measurement unit comprises:
a dial gauge including a spindle equipped with a measurer at an end thereof; and
a stopper provided on an outer circumferential surface of the spindle, and
the each of the gauge jigs comprises:
a first block portion provided in the support block;
a second block portion provided on a side of the first block portion; and
a horizontal hole portion formed through the first block portion and the second block portion in the width direction of the cooling plate so that the measurer comes into contact with the end of the extension plate.
3 . The inspection device of claim 1 , wherein the second measurement unit comprises:
a dial gauge including a spindle equipped with a measurer at an end thereof;
a support bar provided on the spindle in a vertical direction of the spindle; and
a pillar block configured to be movable along the support bar, and
the each of the gauge grooves is formed in a shape corresponding to a lower part of the pillar block.
4 . The inspection device of claim 1 , wherein each of the height blocks is located below a point where the cooling plate and the clamp come into contact and below a point where the cooling plate and the second measurement unit come into contact, so that the cooling plate is not deformed.
5 . The inspection device of claim 2 , further comprising:
a zero point unit provided on the base and adjusting a zero point of the first measurement unit,
wherein the zero point unit comprises:
a support portion provided on the base;
a holding portion located above the support portion;
a supporting portion provided on the support portion to support the holding portion; and
a vertical hole portion formed through the holding portion in a height direction of the holding portion.
