Inspection device for the appearance of pogo pins
Disclosed is an inspection device for an appearance of a pogo pin, including: a seating portion configured to seat the pogo pin thereon; a pogo pin posture adjuster configured to adjust a posture of the pogo pin based on magnetic force by adjusting a position of a magnet placed under the seating portion; a rotation unit configured to rotate the seating portion; a coaxial aligner configured to coaxially align a rotation center of the pogo pin with the rotation unit; and at least one vision module configured to acquire images of the pogo pin seated on the seating portion. According to the disclosure, the inspection device for the appearance of the pogo pins ensures the accuracy and speed in inspecting the appearance of the pogo pin.
1 . An inspection device for an appearance of a pogo pin, comprising:
a seating portion configured to seat the pogo pin thereon;
a pogo pin posture adjuster configured to adjust a posture of the pogo pin based on magnetic force by adjusting a position of a magnet placed under the seating portion;
a rotation unit configured to rotate the seating portion;
a coaxial aligner configured to coaxially align a rotation center of the pogo pin with the rotation unit; and
at least one vision module configured to acquire images of the pogo pin seated on the seating portion.
2 . The inspection device of claim 1 , wherein the vision module comprises a first vision module configured to acquire images of the pogo pin from a lateral side.
3 . The inspection device of claim 2 , wherein the first vision module comprises a first camera and a rear lighting unit provided on one side of an inspection area.
4 . The inspection device of claim 3 , wherein the first vision module comprises a first lighting unit configured to irradiate light toward a lateral surface of the pogo pin.
5 . The inspection device of claim 4 , wherein the posture adjuster is configured to rotate depending on the rotation unit.
6 . The inspection device of claim 5 , wherein
the rotation unit rotates a predetermined angle to change an angle of the pogo pin, and
the first vision module operates to acquire silhouette image whenever the pogo pin is rotated a predetermined angle.
7 . The inspection device of claim 6 , wherein the vision module is configured to acquire images of the pogo pin while the pogo pin is uprightly erected.
8 . The inspection device of claim 7 , wherein the first vision module operates to acquire lateral-view images of the pogo pin while the first lighting unit is operating.
9 . The inspection device of claim 1 , wherein the vision module comprises a second vision module configured to acquire images of the pogo pin from above.
10 . The inspection device of claim 9 , wherein the second vision module comprises a second camera, and a second lighting unit configured to irradiate light toward a top surface of the pogo pin.
11 . The inspection device of claim 1 , wherein the pogo pin posture adjuster comprises:
a first adjusting unit configured to adjust a position of the magnet in a first direction on a horizontal plane; and
a second adjusting unit configured to adjust the position of the magnet in a second direction perpendicular to the first direction.
12 . The inspection device of claim 11 , wherein the first adjusting unit comprises a first upper portion, a first lower portion, and a guide configured to restrict a direction in which the first upper portion moves relative to the first lower portion.
13 . The inspection device of claim 11 , wherein the second adjusting unit comprises a second upper portion, a second lower portion, and a guide configured to restrict a direction in which the second upper portion moves relative to the second lower portion.
