Figure 4 The tracks shown are placed side by side and facing each other, and the synchronous belts 62 on the first supporting surfaces 21 of the two groups of tracks support the side conveyance of the circuit board.

[0038] Combination Figure 5 As shown, when it is necessary to install the belt 72 transmission device on the track, adjust the installation orientation of the support bar 2 so that the second support surface 22 faces upward, install the corresponding pulley 71 on the installation portion 11, and the partial segment of the belt 72 is laid on the second support surface 22, passes through the pulley 71 and then goes around the circulation guide groove 14, then goes down through the guide wheel 3 of the change groove 16, and then goes around the output wheel of the belt motor 73, forming a circulating belt 72 transmission, and the two groups are connected as shown in FIG. Figure 5 The tracks shown are placed side by side and facing each other, and the belts 72 on the second support surfaces 22 of the two sets of tracks support the side conveyance of the circuit board.

[0039] Combination Figure 6 and Figure 7 As shown, when it is necessary to install a chain 82 conveying device on the track, the support bar 2 is pulled out, and the corresponding sprocket 81 is installed on the mounting portion 11. The partial segment of the chain 82 is laid on the chain support groove 13, and then passes through the sprocket 81 to the circulation guide groove 14, and then passes downward through the guide wheel 3 of the change groove 16, and then passes around the output wheel of the sprocket motor 83, forming a circulation sprocket 81 transmission.
