The tape guiding bridge module (9) of the system (1) is the automation means of the system that performs the automatic conveyance of carrier tape (C) between first arm module (7) and carrier tape rail track module (5). This has solved the significant problem faced by the conventional inspection system whereby the manual tape attaching work is alleviated. As further shown in FIGS. 3-C and 3-D, the tape guiding bridge module (9) comprising at least a bridge (91) connecting the rail track (51) of the carrier tape rail track module (5) and the temporary take-up reel (71) of the first arm module (7), wherein the carrier tape (C) is conveyed to the bridge (91) automatically and subsequently inserted into the temporary take-up reel (71) as it moves.

It is contemplated that plurality of sensors is provided proximally to said bridge (91) to further detect the presence, size and width of the incoming carrier tape from the rail track (51), hence enabling the bridge (91) to adjust its width corresponding to the width of the carrier tape, although the size of the carrier tape (C) has already been pre-set by operators initially. The bridge (91) will firstly remain at its standby position before receiving the carrier tape, and when the incoming carrier tape (C) is detected, the bridge (91) will automatically be adjusted to the width of the carrier tape (C) for smooth conveyance of carrier tape (C) into the temporary take-up reel (71). When the leading end of the carrier tape (C) is clamped by the insertion slots (750, 752) of the first cylindrical body (75a) and concave member (75b), the bridge (91) will return back to its standby position for the smooth winding process of said carrier tape (C) on the temporary take-up reel (71) while the rotary shaft (74) is rotated by the motor assembly (79). It is pertinent to note that said temporary take-up reel (71) is not rotated during the winding process or when the rotary module (73) is rotated by the motor assembly.

[0069] Referring to FIG. 9, the inspection module (11) of the system (1) is disposed at a position proximally to the carrier tape rail track module (5), preferably said inspection module (11) may be disposed above or below said carrier tape rail track module (5).

According to the preferred embodiment of the present invention, the inspection module (11) remains at a standby position and does not inspect the carrier tape (C) when the carrier tape (C) is being conveyed on the rail track (51) from the feeder reel module (3) to the first arm module (7). When the carrier tape (C) is wound on the temporary take-up reel (71) of the first arm module (7), the rear end of the carrier tape (C) does not wind into the temporary take-up reel (71) and remains on the rail track (51) of the carrier tape rail track module (5). The rail track (51) and the rotary shaft (74) are then rotated in the opposite direction to rewind the carrier tape (C) back to the feeder reel module (3). During the rewinding process, the inspection module (11) moves to its inspecting position and starts inspecting the carrier tape (C) starting from its rear end to detect if there is any defect. In other words, the inspection process commences on the rear end of the carrier tape (C) and only commences when the carrier tape is rewound from the first arm module (7) to the feeder reel module (3). It is pertinent to note that said temporary take-up reel (71) is not rotated during the rewinding process.

[0070] Alternatively, it is contemplated that the inspection module (11) may be configured to moves to its inspecting position to inspect the carrier tape while the carrier tape is moving from the feeder reel module (3) to the first arm module (7), hence providing double or dual inspection on the carrier tape (C).
