According to a general concept of the present invention, there is provided an automatic assembling system for inserting an elongated first member into a hole of a second member, comprising: a movement unit configured to move the second member in a horizontal plane; a vision alignment unit under the visual guidance of which the movement unit moves the second member to a position where the first member is aligned with the hole of the second member; and a step insertion unit configured to grip and move the first member so as to insert the first member into the hole of the second member step by step.
Fig.1 is an illustrative perspective view of an automatic assembling system according to an exemplary embodiment of the present invention.
As shown in Fig. l, in the illuminated embodiment, the automatic assembling system is used to insert an elongated first member into a hole of a second member, for example, insert an elongated optical fiber 600 into a hole of an optical ferrule 500, for example, a fiber optic connector, as shown in Figs.2-3. But the present invention is not limited to this, the automatic assembling system of the present invention is adapted to insert any elongated wire-like member into a hole of another member.
In an exemplary embodiment, as shown in Fig. l, the automatic assembling system mainly comprises a movement unit 101, 102, a vision alignment unit 201, 202 and a step insertion unit 301, 302, 401, 402.
As shown in Fig. l, in an exemplary embodiment, movement unit 101, 102, a vision alignment unit 201, 202 and a step insertion unit 301, 302, 401, 402 are mounted on a horizontal station or base 100. The movement unit 101, 102 is configured to move the optical ferrule 500 in a horizontal plane (see Fig.2). The movement unit 101, 102 moves the optical ferrule 500 to a position where the optical fiber 600 is aligned with the hole of the optical ferrule 500 under the visual guidance of the vision alignment unit 201, 202. The step insertion unit 301, 302, 401, 402 is configured to grip and move the optical fiber 600 so as to insert the optical fiber 600 into the hole of the optical ferrule 500 step by step.
As shown in Fig. l, in an exemplary embodiment, the movement unit mainly comprises a first moving arm 101 and a second moving arm 102. The first moving arm 101 is configured to be capable of moving in a first direction in the horizontal plane, and the second moving arm 102 is configured to be capable of moving in a second direction perpendicular to the first direction in the horizontal plane.
In an exemplary embodiment, as shown in Fig. l, the first moving arm 101 is mounted on the second moving arm 102 to be capable of moving with the movement of the second moving arm 102 in the second direction. A fixture feature 110 for fixing the optical ferrule 500 is formed in the first moving arm 101. In an example, the fixture feature 110 may be configured to be a position hole formed in the first moving arm 101, and the optical ferrule 500 may be inserted into and fixed in the position hole. In this embodiment, the axis of the hole of the optical ferrule 500 is positioned in a vertical direction perpendicular to the horizontal plane. In this way, when the optical ferrule 500 is fixed in the fixture feature 110 of the first moving arm 101, the optical ferrule 500 can be moved in the horizontal plane with the movement of the first moving arm 101 and the second moving arm 102. As a result, the coordinate position of the optical ferrule 500 in the horizontal plane can be freely adjusted to align the axis of the hole of the optical ferrule 500 to the axis of the optical fiber 600.
In an exemplary embodiment of the present invention, the first moving arm 101 and the second moving arm 102 may be driven by individual driving systems, respectively, to move in the respective directions thereof. Fig.4 is an illustrative view of a pair of crossing cameras 201, 202 of Fig. l .
As shown in Fig. l and Fig.4, the vision alignment unit mainly comprises a first camera 201 and a second camera 202.
In an exemplary embodiment of the present invention, as shown in Fig. l and Fig.4, the first camera 201 is configured to take a first picture of the optical ferrule 500 and the optical fiber 600 along a first shooting direction in the horizontal plane. And the second camera 202 is configured to take a second picture of the optical ferrule 500 and the optical fiber 600 along a second shooting direction different from the first shooting direction in the horizontal plane. In an example, as shown in Fig.4, the first shooting direction is perpendicular to the second shooting direction, so as to facilitate the coordinate conversion and position calculation. But the present invention is not limited to this, an angle between the first shooting direction and the second shooting direction may be set to be 45 degrees, 60 degrees, or other angle.
Hereafter, it will describe the vision alignment principle of the vision alignment unit with reference to Figs. 5a, 5b, 6a and 6b.
Fig.5a and Fig.5b show a set of pictures taken by a pair of crossing cameras of Fig. l . Fig.5a shows a first picture taken by the first camera 201, and Fig.5b shows a second picture taken by the second camera 202.
As shown in Fig.5a and Fig.5b, the axis of the optical fiber 600 is offset from the axis of the hole of the optical ferrule 500, and is not aligned to the axis of the hole of the optical ferrule 500. Accordingly, based on the taken pictures, a position of the axis of the hole of the optical ferrule 500 relative to the axis (an original point) of the optical fiber 600 in a first coordinate system defined by the first and second shooting directions may be calculated. Then, the position of the axis of the hole of the optical ferrule 500 relative to the axis (the original point) of the optical fiber 600 in the first coordinate system may be converted into a position of the axis of the hole of the optical ferrule 500 relative to the axis (the original point) of the optical fiber 600 in a second coordinate system defined by the first and second movement directions of the first and second moving arms. Thereafter, based on the position of the axis of the hole of the optical ferrule 500 relative to the axis (the original point) of the optical fiber 600 in the second coordinate system, the first and second moving arms 101, 102 may be controlled to move the optical ferrule 500 in the second coordinate system to a position where the axis of the hole of the optical ferrule 500 is aligned to the axis of the optical fiber 600.
Fig.6a and Fig.6b show another set of pictures taken by a pair of crossing cameras of Fig. l . Fig.6a shows a first picture taken by the first camera 201, and Fig.6b shows a second picture taken by the second camera 202.
As shown in Fig.6a and Fig.6b, the axis of the optical fiber 600 is aligned to the axis of the hole of the optical ferrule 500. Thereby, it may determine that the optical ferrule 500 has been moved to the position where the axis of the hole of the optical ferrule 500 is aligned to the axis of the optical fiber 600. Then, the first and second moving arms 101, 102 are stopped and locked.

In this way, the first gripper 301 and the second gripper 302 may grip two different locations of the optical fiber 600 in the vertical direction at the same time, improving the stability of gripping the optical fiber 600.
Also, in an exemplary embodiment of the present invention, the second gripper 302 below the first gripper 301 is disposed at a position proximal to the upper end surface of the optical ferrule 500. As a result, a distance from the second gripper to the upper end surface of the optical ferrule 500 is very short, preventing the optical fiber 600 from being bent or broken.
In an exemplary embodiment of the present invention, the first gripper 301 and the second gripper 302 each comprises an individual driving mechanism for operating them to grip or loose the optical fiber 600. The first gripper 301 or the second gripper 302 may be any suitable gripper in the prior art.
As shown in Figs.1-2, the first moving mechanism 401 is configured to move both the first gripper 301 and the second gripper 302 downward by a step distance in the vertical direction when the first gripper 301 and the second gripper 302 grip the optical fiber 600 at the same time, and the second moving mechanism 402 is configured to move only the second gripper 302 upward by a step distance in the vertical direction when the second gripper 302 looses the optical fiber 600. In an exemplary embodiment, the first moving mechanism 401 comprises a first servo motor, and the second mechanism 402 comprises a second servo motor.
