The servo motor has a brake function, can accurately control the rotary table to rotate forward and backward for 90 degrees, and can complete the conveying of materials at a right-angle turning position.

The rotary table and the two conveying lines are provided with roller sets. Considering that the roller has larger load, the chain transmission has large transmission power and strong overload capacity, and the roller cannot slip, thereby influencing the transportation efficiency and even causing the material frame to collapse, the three roller groups all adopt the chain transmission mode. As shown in FIG. 5, the transmission scheme is that two chain wheels are fixed on each roller in a welding mode, and each two adjacent rollers are driven by a chain. And the three roller groups are respectively provided with a driving motor, and 3 driving motors are used for respectively driving the chain wheel on the first roller of each roller group to rotate so as to drive the other rollers of each roller group to rotate.

In addition, install the biax cylinder on shaped steel through the cylinder block that fig. 6 shows to the centre gripping sheet metal component that fig. 7 shows is installed on the biax cylinder as the centre gripping part, and the cylinder promotes the centre gripping sheet metal component, forms a stabilising arrangement and presss from both sides tight pallet, forbids the pallet to produce relative movement, thereby avoids arousing empting of material frame on the pallet.

2 guide sheet metal parts with structures as shown in figure 8 are respectively arranged on the section steel of the rotary table part and the section steel of the conveying line to form a guide device, so that the phenomenon that the pallet deviates from a track and fails in transferring is avoided. Because the chain wheel is arranged on one side of the roller group, the pallet is not positioned in the middle of the two section steels, and the widths of the guide sheet metal parts on the two sides are different.

The laser sensor is arranged on the rotary table and used for detecting the position of the pallet movement. The laser sensor is provided with a laser emitting end and a laser receiving end, the laser emitting end and the laser receiving end are arranged on the same straight line during installation, when the pallet reaches a designated position, laser is blocked, the receiving end cannot detect a laser signal and then feeds the laser signal back to the driving motor, the driving motor immediately brakes, and the pallet also stops moving forwards along with the laser signal.
