Abstract
When a movable member (14) is moved from a gripping position in which a circuit board (2) was gripped by the movable member (14) and a stationary member (13), a separation mechanism (7, 12) forcibly separates the circuit board from the stationary member (13), to thereby prevent the occurrence of a state in which the circuit board (2) is stuck to the stationary member.
Claims9
A circuit board holding apparatus for holding a circuit board by gripping a pair of opposed edge portions of the circuit board, comprising:
- stationary members to be arranged opposite the edge portions of the circuit board for contacting a front surface of the circuit board;
- movable members movable with respect to said stationary members between a board gripping position in which the edge portions of the circuit board are gripped between said movable members and said stationary members when the circuit board is disposed therebetween, and a board releasing position, for contacting a rear surface of the circuit board and moving the circuit board in a thickness direction thereof when said movable members move from said board releasing position toward said board gripping position;
- and
- a separation mechanism for forcibly separating the circuit board from said stationary members in a direction of movement of said movable members when said movable members move from said board gripping position to toward said board releasing position to release the circuit board from said stationary members;
- wherein said separation mechanism comprises at least one pressing member mounted to one of said stationary members to cause the circuit board to be put in pressure contact with at least one of said movable members.

A circuit board holding apparatus for holding a circuit board by gripping a pair of opposed edge portions of the circuit board, comprising:
- stationary members to be arranged opposite the edge portions of the circuit board for contacting a front surface of the circuit board;
- movable members movable with respect to said stationary members between a board gripping position in which the edge portions of the circuit board are gripped between said movable members and said stationary members when the circuit board is disposed therebetween, and a board releasing position, for contacting a rear surface of the circuit board and moving the circuit board in a thickness direction thereof when said movable members move from said board releasing position toward said board gripping position;
- and
- a separation mechanism for forcibly separating the circuit board from said stationary members in a direction of movement of said movable members when said movable members move from said board gripping position toward said board releasing position to release the circuit board from said stationary members;
- wherein said separation mechanism comprises a suction unit including a suction section to be arranged on a rear surface side of the circuit board for attracting the rear surface of the circuit board by suction, and a drive unit which moves said suction section in the direction of movement of said movable members when said movable members are moved;
- and
- wherein said separation mechanism operates to separate the circuit board from said stationary members on confronting sides of the circuit board when said movable members move from said board gripping position toward said board releasing position.

- wherein a control unit is provided to control a start of movement of said movable members from said board gripping position toward said board releasing position, a start of suction of the circuit board by said suction unit, and movement of said suction unit by said drive unit;
- and
- wherein said separation mechanism operates to separate the circuit board from said stationary members on confronting sides of the circuit board when said movable members move from said board gripping position toward said board releasing position.
