Description

Technical Field

[0001] The utility model relates to the technical field of PCB board pressing, in particular to a device for preventing errors in sorting of multi-layer PCB stacking boards. Background Art

[0002] PCB boards are important components for the production of electronic products such as computers, mobile phones and tablets. In the PCB pressing production process, stacking is a very critical process. In the current PCB production process, during the stacking process, personnel rely entirely on visual inspection to see if there are any errors. However, there is a risk of missed inspections when personnel self-check whether the stacked boards are stacked incorrectly.

[0003] After searching, such as the Chinese publicly authorized patent "A PCB pressing and stacking anti-misstacking device", the publication number is "CN217796924U". This patent utility model sets a layer guide nameplate, a CCD camera, a computer controller, a pressing plate, a groove, a solenoid valve, a spring and a blocking block. When the order of the layers read by the CCD camera is wrong or some layers are missing, the computer controller will display an alarm screen and remind the personnel to stack the plates incorrectly. When a stacking error occurs, the computer controller drives the solenoid valve to open it and releases the spring, so that the blocking block pops out to prevent the staff from continuing to stack the plates until the fault is eliminated, and then manually close the solenoid valve, re-jam the spring, and retract the blocking block, so as to continue normal stacking.

[0004] However, in the above case, the blocking block needs to be manually reset by the user after it is ejected, which is troublesome to operate and reduces production efficiency.

[0005] Therefore, a multi-layer PCB stacking sorting error prevention device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a multi-layer PCB stacking error prevention device in order to solve the above-mentioned problem, which improves the problem that the user needs to manually reset the blocking block after it is ejected in the comparative case, which is cumbersome to operate and reduces production efficiency.

[0009] Preferably, sliders are fixedly connected to both sides of the blocking block, and sliding grooves are opened on the inner walls of the two sides of the movable seat.

When a placement error is found, the controller 5 controls the electric push rod 61 to start, and the electric push rod 61 drives the moving seat 62 to move out of the storage groove 64.
