Description

A PCB board breaking device with wide application range

Technical Field

The utility model relates to the field of PCB board breaking devices, and in particular to a PCB board breaking device with a wide application range.

Background Art

The application document with the publication number CN207560480U discloses a PCB board bending device. In order to meet the requirements of plug-in components and wave soldering, it is necessary to set process edges on both sides of the PCB, and finally the process edges need to be bent off. At present, the method of tools plus manpower or simple tooling plus manpower is mostly used, which is heavy work, with a high error rate and low production efficiency. The utility model sets a plug-in port on the side of the flip plate, sets an inclined surface at the edge of the plane of the flip plate, the circular shaft on the flip plate and the through hole on the base are clearance-matched, the reduction motor is connected to the flip plate, and a micro switch is set on the side of the flip plate. The upper plane of the support plate is flush with the lower plane of the plug-in port. After the PCB board is placed in place in the plug-in port, the reduction motor drives the flip plate to rotate and bends off the process edge, which effectively reduces the labor intensity and error rate of workers and improves production efficiency. The utility model is mainly used to break off the process board on the PCB.

However, the micro switches used for positioning the PCB board on the above-mentioned device are fixedly installed, that is, the distance between the two sets of micro switches is fixed, resulting in that only PCB boards of a certain size can be placed between the two sets of micro switches to achieve the board bending operation, resulting in a low scope of application of the device, and PCB boards of different sizes cannot be processed.

The Chinese utility model patent application number 202320188053.5 proposes a PCB bending device, but there are still some shortcomings:

First, each time the board is opened, the clamping mechanism needs to be operated to clamp and release, which is cumbersome and will reduce the overall efficiency of opening the board. If the size is maintained after the first opening, it will be difficult to quickly insert the PCB board later.

Second, the process edge part is not clamped when the board is broken, and the breaking process may cause the process edge part to pop out, which is not conducive to subsequent collection and cleaning, and also poses certain safety hazards to the staff.

Therefore, the utility model proposes a PCB board breaking device with a wide range of applications to solve the above problems.
