Abstract

An automatic cleaning device of a pattern jig after laser notching includes: a rotary rod coupled to the center of a pattern jig to rotate the pattern jig; a pair of brushes rotatably installed on a side of a brush unit; brush rotation motors for rotating the brushes; left and right brush carriers for carrying the brushes left and right; a vertical brush unit carrier installed at the brush unit to be movable up and down; a forward and backward brush unit carrier coupled to the vertical brush unit carrier and moving the brush unit forward and backward; and a forward and backward laser brush unit carrier coupled to the forward and backward brush unit carrier and moving together with the forward and backward brush unit carrier.

Claims (14)

1 . An automatic cleaning device for a pattern jig after the pattern jig has been used for laser notching an electrode with a laser emitted by a laser emitter, the automatic cleaning device comprising:

a rotary rod rotatably coupled to the center of the pattern jig to rotate the pattern jig;

a rotation actuator operatively coupled to the rotary rod to rotate the rotary rod to rotate the pattern jig;

a brush unit including a pair of brushes rotatably coupled to a side of the brush unit;

brush rotation motors installed in the brush unit to rotate the brushes;

left and right brush carriers for carrying the brushes left and right;

a vertical brush unit carrier installed at the brush unit to move the brush unit upward and downward;

a forward and backward brush unit carrier coupled to the vertical brush unit carrier and configured to move the brush unit forward and backward; and

a forward and backward laser brush unit carrier coupled to the forward and backward brush unit carrier and moving together with the forward and backward brush unit carrier,

wherein in order to remove contaminants of the pattern jig, the pair of brushes are moved away from each other in the left and right direction, the pattern jig is rotated toward the brush unit, and the pair of brushes are brought into contact with the pattern jig by moving forward the brush unit and moving the pair of brushes towards each other in the left and right direction, whereby the brushes are rotated to remove the contaminants from the pattern jig.

2 . The automatic cleaning device of claim 1 , wherein the pattern jig is rotatably coupled to the forward and backward brush unit carrier through the rotary rod and the rotation actuator.

3 . The automatic cleaning device of claim 1 , further comprising a pair of combs that are moved up and down by a solenoid, wherein the pair of combs are installed at upper ends of the brushes to clean the brushes when the brushes are rotated in contact with each other.

4 . The automatic cleaning device of claim 1 , wherein the left and right brush carriers are driven in opposite directions to move the brushes toward each other and away from each other.

5 . The automatic cleaning device of claim 1 , wherein moving the brushes away from each other comprises driving the left and right brush carriers in opposite directions.
