The work is coherent, solving the problems of low efficiency and long interval time of manual feeding. The device has a compact structure, high working efficiency, and greatly increases the replacement efficiency of the plate rack.

[0026] In order to guide and position the plate rack, side baffles 12 and a detection sensor 5 are arranged on the side of the plate rack conveying wall panel 1. The detection sensor 5 is an optical fiber sensor, and the plate rack on the upper part of the conveying belt 3 can be detected through the detection sensor 5. In order to connect and install the detection sensor 5, as shown in the appendix Figure 1 As shown, a sensor mounting seat 13 is fixedly installed on the side of the plate rack conveying wall panel 1 through bolts. The detection sensor 5 is fixedly installed in the middle of the sensor mounting seat 13. The detection end of the sensor mounting seat 13 faces the upper conveying side of the conveying belt 3. The in-place situation of the plate rack is judged through the detection signal of the detection sensor 5 to achieve accurate docking. The side baffles 12 are arranged in pairs, and the two side baffles 12 are symmetrically fixed on the upper side edges of the two side plate rack conveying wall panels 1 respectively. Through side pushing and guiding, the plate rack can be rectified and positioned during the movement process.

[0027] The supporting component is used for the moving support of the plate rack. The supporting component includes a mounting shaft column 6, a plate rack supporting wheel 7, a spring 8 and a free roller 9. A plurality of free rollers 9 are provided. As shown in the appendix Figure 1As shown in the figure, a plurality of free rollers 9 are evenly and rotatably installed at equal intervals on the side of the plate rack conveying wall plate 1 through a rotating shaft. The free rollers 9 are rotatably supported in the middle of the conveying belt 3.

[0028] Working principle or structural principle: During work, the driving motor 4 is used as the power to drive the synchronous belt 11 to drive the main transmission shaft to rotate. The main transmission shaft drives the conveying belt 3 to move together to realize the moving conveying of the plate rack. Driven by the conveying belt 3, the plate rack moves to the grabbing position of the sheet material. During the moving process, the plate rack is offset and corrected under the pushing and guiding action of the side baffle 12 on the side, and the position of the plate rack is detected by the detection sensor 5 to judge whether the movement of the plate rack is in place, ensuring the accuracy of docking. Then, the plate loading and unloading machine moves and transports the sheet material on the upper part of the plate rack. During the transportation process, the conveying belt 3 drives the plate rack to perform calibration displacement to automatically adjust the feeding position. At the same time, when the PCB sheet material becomes less, the conveying belt 3 drives the plate to be in a suitable position to avoid the situation of not being able to suck or firmly suck the plate, resulting in plate dropping and jamming, damaging the machine equipment or stopping the machine. When the sheet material is used up, after being grabbed and transported out, the driving motor 4 rotates reversely to drive the plate rack to move out. Then, the next plate rack is replaced, and the movement positioning of the plate rack is completed through the cooperation of the detection sensor 5 and the side baffle 12 to ensure the accurate placement of the plate rack. Then, the PCB turning device returns and coincides with the plate rack again to perform the plate placing action for the next PCB board;

[0029] After the equipment is used, when maintaining or repairing and replacing the plate rack support wheel 7, only need to loosen and remove the fastening bolt 18 in the middle of the installation shaft column 6, then hold one side of the installation shaft column 6 and push hard to make the connecting plug column 16 further inserted, and through retraction, the end of the installation shaft column 6 is separated from the connecting convex column 14 on the side of the free roller 9, and the disassembly operation of the plate rack support wheel 7 can be completed.

[0030] In summary, this conveying mechanism adopts a belt-type conveying structure. The conveying belt 3 arranged above the plate frame for conveying the wallboard 1 is used to replace manual movement and conveyance of the plate frame. With the positioning detection of the detection sensor 5, the loading and unloading operations of the plate frame can be automatically completed, and it can be perfectly connected and coordinated with the PCB automatic board loading and unloading machine. The continuous operation solves the problems of low efficiency and long interval time of manual feeding. The device has a compact structure and high working efficiency, greatly increasing the replacement efficiency of the plate frame. Moreover, the plate frame support wheel 7 is provided with a split-type detachable structure. The middle section of the mounting shaft column 6 is connected and installed by using a plug-in structure in cooperation with a spring 8. Both ends of the mounting shaft column 6 are supported and installed by fitting with the connecting convex columns 14 on the side of the free roller 9. When needed, the plate frame support wheel 7 can be quickly disassembled and assembled. The structure is simple and the disassembly and assembly are convenient, which is conducive to the replacement and maintenance operations of the plate frame support wheel 7.
