Abstract

A detaching apparatus includes a bench, a first supporting member attached to the bench, a convey system, a positioning member, a second supporting member, and a detaching member. The convey system is attached to the first supporting member for conveying a circuit board. The positioning member is attached to the first supporting member for positioning the circuit board. The second supporting member is attached to the bench and aligning with the first supporting member. The detaching member is attached to the second supporting member and includes a sliding bracket moving vertically relative to the bench, a moving block moving horizontally in the sliding bracket, a blade attached to the moving block, and a vacuum suction cup attached to the moving block and aligning with the blade.

First claim

What is claimed is:

1 . A detaching apparatus for detaching a component from a circuit board, the detaching apparatus comprising:
a bench; a first supporting member attached to the bench; a convey system attached to the first supporting member for conveying the circuit board; a positioning member attached to the first supporting member for positioning the circuit board; a second supporting member attached to the bench and aligning with the first supporting member; and a detaching member attached to the second supporting member and comprising a sliding bracket moving vertically relative to the bench, a moving block moving horizontally in the sliding bracket, a blade attached to the moving block, and a vacuum suction cup attached to the moving block and aligning with the blade; wherein the blade is moved between the component and the circuit board to separate the component from the circuit board and the vacuum suction cup picks the component up.

2 . The detaching apparatus of claim 1 , wherein the first supporting member comprises a pair of rails attached to the bench, the convey system comprises a pair of convey belts respectively attached to inner sides of the rails and driven by a driving member, the circuit board is supported on a tray, the tray is conveyed by the convey belts.

3 . The detaching apparatus of claim 2 , wherein the positioning member comprises a pair of L-shaped abutting plates respectively attached to the rails, a stopping member, and a pair of abutting blocks located between the rails, each abutting plate comprises a connecting portion attached to an outside of the rail, and an abutting portion extending perpendicularly from the connecting portion and located above the corresponding rail, the abutting portions are capable of abutting against a top of the tray, the abutting blocks are driven to move the tray vertically to sandwich the tray between the abutting blocks and the abutting portions.

4 . The detaching apparatus of claim 3 , wherein a position pin protrudes from a top surface of each abutting block, the tray defines two position holes for respectively receiving the position pins.

5 . The detaching apparatus of claim 3 , wherein the positioning member further comprises a stopping member located between the rails, the stopping member is driven to move vertically and comprises a stopping bar capable of blocking an end of the tray.

6 . The detaching apparatus of claim 2 , further comprising a locating member attached to the second supporting member and opposite to the detaching member, wherein a pressing block is driven to move vertically and capable of abutting against a top of the circuit board.

7 . The detaching apparatus of claim 6 , wherein the locating member comprises a connecting block driven by a cylinder, the pressing block located below the connecting block, a plurality of guiding pins located between the connecting block and the pressing block, and a plurality of resilient members respectively fitted about the guiding pins, an end of each guiding pin is mounted to the pressing block, and the other end of the each guiding pin is slidably connected to the connecting block.

8 . The detaching apparatus of claim 2 , further comprising a control device, wherein the driving member, the convey belts, the sliding bracket, the moving block, the convey system are controlled by the control device.

9 . The detaching apparatus of claim 8 , further comprising a first sensor, a second sensor, and a third sensor, wherein the first sensor, the second sensor are located between the rails and controlled by the control device, the first sensor and the third sensor are located near two opposite ends of the rails, the second sensor is located between the first sensor and the third sensor.

10 . The detaching apparatus of claim 1 , wherein the second supporting member comprises an installing plate located above the first supporting member, and two spaced and opposite connecting plates mounted to a side of a bottom surface of the installing plate, each of the two spaced and opposite connecting plate comprises a connecting portion extending down from the installing plate and an extending portion extending from a distal end of the connecting portion toward the other connecting plate, the sliding bracket is slide between the connecting portions and is capable of being stopped by the extending portions.

11 . A method for separating an electronic component from a circuit board, comprising:
moving a circuit board horizontally into a cutting location via a convey system; locking the horizontal position of the circuit board; moving the circuit board and/or a cutting tool closer to each other, such that a blade on the cutting tool is vertically aligned between the electronic component and the circuit board and horizontally offset from the electronic component; moving the cutting tool horizontally such that the blade moves between the electronic component and the circuit board to sever any connection there between; moving the circuit board and/or a cutting tool away from each other, such that the cutting tool is moved to a position relative to the circuit board that does not impede horizontal movement of the circuit board; and moving the circuit board horizontally out of the cutting location via the convey system.
