Automatic cutting machine for PCB

Abstract

The invention discloses an automatic cutting machine for a PCB, and relates to the technical field of PCB cutting machines, in particular to the automatic cutting machine for the PCB. The machine comprises a fixed box, two feeding rollers are movably installed on the left side of the inner part of the fixed box, two transmission rollers located on the right sides of the feeding rollers are movablyinstalled inside the fixed box, and dividing knives movably sleeve the outer parts of the transmission rollers. According to the automatic cutting machine for the PCB, adjusting screws on the front and rear sides are rotated to drive fixing plates and auxiliary sliding rollers on the front and rear sides to move, distances between the fixing plates and the auxiliary sliding rollers on the front and rear sides are adjusted according to the width of the PCB, when feeding of the PCB is carried out, the PCB is limited by the fixing plates on the front and rear sides to ensure that the PCB can only move left and right, the PCB is prevented from shaking back and forth, changing of front and rear positions of the PCB during continuous feeding is avoided, and the quality of the PCB after dividingis ensured.

Description

technical field [0001] The invention relates to the technical field of PCB board cutting machines, in particular to an automatic cutting machine for circuit PCB boards. Background technique [0002] PCB, the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. Before the appearance of PCB, the interconnection between electronic components was done by direct connection of wires. Today, printed circuit boards have definitely occupied an absolute control position in the electronics industry.

Problems solved by technology

[0003] When producing PCB boards, it is necessary to cut the material, that is, to cut a large sheet of material into small pieces that meet the requirements. In the prior art, a cutting machine is usually used to divide and cut the PCB board. The existing cutting machine is feeding Auxiliary feed rollers are installed at the end of the feeder. When loading, slide the entire PCB board along the auxiliary feed rollers for loading. Although the difficulty of loading is reduced, the feed end of the feeder does not have two sides of the PCB board. The side-limiting device is easy to shift when the PCB board gradually moves to the inside of the cutting machine, resulting in a decrease in the quality of the finished product; in addition, the existing cutting machine usually drives the cutting knife to rotate through the driving device to divide the PCB board , when the cutting distance of the PCB board changes, it is usually necessary to open the cutting machine chassis, and then use the tool to rotate the screw that limits the splitting knife, so as to realize the adjustment of the splitting knife distance, the operation is time-consuming and labor-intensive, and the labor intensity is relatively large; in addition , after the existing cutting machine divides the PCB board, the PCB boards are usually scattered and piled up at the outlet of the cutting machine, and the staff needs to manually sort them out later, which is labor-intensive and reduces work efficiency.
