送され、検査装置１５の位置を通過する。The substrate conveyance jig 3 holding the substrate 1 in a fixed state is conveyed by the upstream conveyor 7. At this time, if there is a preceding substrate 1 on the constant speed conveyor 4, the stopper 14 is projected upward to restrict the movement of the substrate conveying jig 3, and the substrate 1 is kept waiting at that position. If there is no preceding substrate 1 on the constant speed conveyor 4, the stopper 14 is lowered and the substrate conveying jig 3 is moved by the pair of rubber rows 213 rotating on the loader 10.
The substrate conveying jig 3 and the substrate 1 are transferred onto the constant speed conveyor 4 by the rotational force of the two sides. The transferred substrate transport jig 3 and the substrate l are transported by the constant speed conveyor 4 and pass the position of the inspection device 15.

査を行なうことができる。At this time, the inspection device 15 performs an automatic visual inspection of the substrate 1. During this inspection, the subsequent substrate 1 on the upstream conveyor 7
At the same time as the transfer of the substrate transfer jig 3 holding the board starts, the stopper 14 is raised and the subsequent substrate transfer jig 3
and prevents the board 1 from entering the inspection section. When the inspection of the substrate l is completed as described above, the pair of rotating rubber rollers 13 of the unloader 11 pinch the side surfaces of the substrate transport jig 3, and the rotational force of the two rotates the substrate transport jig 3 and the substrate 1. It is forcibly taken out from the constant speed conveyor 4 and transferred onto the downstream conveyor 8. As a result, the substrate 1 is no longer on the constant speed conveyor 4, so the subsequent substrate transfer jig 3 and the substrate 1, which have been waiting with the stopper 14 depressed downward, are moved from the upstream conveyor 7 by the loader 10 as described above. Transfer onto constant speed conveyor 4. Thereafter, by repeating the same operation as described above, the substrates 1 can be sequentially transported and inspection can be performed during this time.

大きいほど顕著になる。In this way, according to the above embodiment, the upstream conveyor 7, which has a faster transport speed than the constant speed conveyor 4, transports the substrate transport jigs 3 and the substrates 1 in a number that exceeds the transport capacity of the constant speed conveyor 4, and then reaches the stopper. The inspection device 15 is placed on standby at 14.
At the same time, the unloader 11 takes out the substrate transport jig 3 and the substrate 1 to the downstream conveyor 8, and the loader 10 inspects the subsequent substrates waiting on the upstream conveyor 7. Since the transport jig 3 and the substrate 1 are transferred onto the constant speed conveyor 4, the time interval between inspections between the preceding substrate 1 and the succeeding substrate 1 can be shortened compared to the conventional example. This effect of shortening the inspection interval becomes more pronounced as the dimensional difference in the transport direction between the substrate 1 and the substrate transport jig 3 shown in FIG. 2 increases.

治具の搬送方向の寸法差が大きいほど大きくなる。Effects of the Invention As described above, according to the present invention, the substrate conveyance jig and the substrate are conveyed by the upstream conveyor whose conveyance speed is higher than that of the constant speed conveyor, are kept waiting at the stopper, and then are transferred onto the constant speed conveyor by the unloader. After the board that has been inspected is forcibly taken out to the downstream conveyor together with the board transport jig, the stopper is depressed and the subsequent board transport jig and board waiting on the upstream conveyor are transferred to the constant speed conveyor using a loader. Since the board can be transferred to the top, it is possible to reduce wasted transport time when the board is not inspected on the constant speed conveyor, and therefore, it is possible to shorten the time interval of automatic visual inspection of the board and improve efficiency. can. The effect becomes larger as the dimensional difference in the transport direction between the substrate and the substrate transport jig increases.
