In an automatic mounting machine (1) for mounting electronic components on circuit boards (9), the circuit boards are placed on a movable Y-wagon (3). When feeding circuit boards to the machine and the Y-wagon and when transporting the circuit boards therefrom, simultaneously several circuit boards (9), which are located at each other, are transported as a train of boards or as one unit. Therefore circuit boards in the machine have their edges inserted in grooves (5) of the Y-wagon (3). Transport devices (11, 17) are provided having similar grooves (13, 19), so that several circuit boards (9) placed in a row can also be placed thereon. In feeding a row of new circuit boards, which have not been mounted, thus the transport devices (11, 17) are placed having their grooves aligned with the grooves of the Y-wagon (3). After that, a fluid cylinder (15) is activated on the transport device (11), where the row of the new circuit boards (9) is located, so that a projection on the end of the piston rod of the cylinder (15) will engage the rear, outer edge of the rearmost circuit board in the row. Thereby the circuit boards are displaced towards and into the grooves (5) of the machine. Another projection on the opposite end of the piston rod then pushes away the finished boards in a direction towards and over to the grooves of the other transport device (17). By means of the simultaneous displacement of several boards an increased velocity is obtained in the replacement of boards. |
