Description

Technical Field

[0001] The utility model relates to the technical field of circuit board collecting machines, in particular to a circuit board collecting machine. Background Art

[0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Before the advent of printed circuit boards, the interconnection between electronic components was achieved by direct connection of wires to form a complete circuit. In modern times, the main advantage of circuit boards is that they greatly reduce wiring and assembly errors, improve the level of automation and production labor rates, and circuit boards need to be collected during batch processing, for which a circuit board collection machine is needed.

[0003] In the existing circuit board collecting machines, when collecting circuit boards, there is often a certain distance between the circuit board discharge port and the collection box, so that when collecting, the circuit board needs to be free-falling at one end. Although this method is feasible, it is easy to damage the circuit board.

[0004] After massive searches, it was found that in the prior art, such as the publication number CN202222313191.X, an automatic board collecting device for circuit boards includes a device body, a vertical plate is vertically installed on the top surface of the device body, a conveying frame is installed above the device body, a conveying roller is slidably installed inside the conveying frame, a mounting seat is vertically installed near the edge of the bottom end of the conveying frame, a support column is slidably connected inside the mounting seat through a pin shaft, and two groups of support columns are arranged, a collecting box is placed on the top surface of the device body, a slide groove is opened on the top surface of the device body, an electric push rod is arranged inside the slide groove, and the other end of the electric push rod is fixedly connected to the outer surface of the support column. The utility model facilitates the conveying and collection of circuit boards by setting a conveying frame, a conveying roller, a support column, a mounting seat and a pin shaft for coordinated use. This method is simple to operate, is convenient for conveying and collecting circuit boards, changes the traditional free-fall collection method, and is convenient for protecting the circuit boards. Although this method can collect and protect the circuit boards well, the side of the conveying roller lacks a limiting mechanism. Once the circuit board is discharged, the moving angle changes, and the circuit board is easy to fall from the side of the conveying roller, making it impossible for the circuit board to fall into the collection box. Therefore, further improvements are needed.

[0005] Therefore, it is necessary to provide a circuit board receiving machine to solve the above technical problems. Utility Model Content
