Embodiment 1

[0025] A method for removing orifice drape on a novel PCB board is characterized in that it comprises the steps:

[0026] Grinding for the first time: put the drilled PCB 1 into the first grinding device for the first grinding. The first grinding device includes a pair of upper and lower grinding wheels, and the grinding wheels are provided with grinding brushes;

[0027] Horizontal 90° steering: through the automatic steering machine arranged between the first grinding device and the second grinding device, the PCB board 1 after the first grinding is rotated horizontally by 90°;

[0028] The second grinding plate: Put the PCB board 1 turned horizontally by 90° into the second grinding plate device for the second grinding plate. The second grinding plate device includes a pair of upper and lower grinding wheels, and the grinding wheel is equipped with a grinding wheel. brush.

Embodiment 2

[0030] A method for removing orifice drape on a novel PCB board is characterized in that it comprises the steps:

[0031] Board placement: use the automatic board placement device to put the drilled PCB board 1 into the first grinding board device in the next step;

[0032] Grinding for the first time: the first grinding device is used to grind the drilled PCB board 1 placed in the automatic plate placing device for the first time. The first grinding device includes two pairs of upper and lower grinding wheels. There are grinding brushes, and the two pairs of grinding wheels turn in the same direction;

[0033] Horizontal 90° steering: through the automatic steering machine arranged between the first grinding device and the second grinding device, the PCB board 1 after the first grinding is rotated horizontally by 90°;

[0034] The second grinding plate: Put the PCB board 1 turned horizontally by 90° into the second grinding plate device for the second grinding plate. The sec...

Embodiment 3

[0040] A method for removing orifice drape on a novel PCB board is characterized in that it comprises the steps:

[0041] Board placement: use the automatic board placement device to put the drilled PCB board 1 into the first grinding board device in the next step;

[0042] Grinding for the first time: the first grinding device is used to grind the drilled PCB board 1 placed in the automatic plate placing device for the first time. The first grinding device includes two pairs of upper and lower grinding wheels. There are grinding brushes, the upper grinding wheel 2 of the first pair of grinding wheels is opposite to the upper grinding wheel 2 of the second pair of grinding wheels, and the lower grinding wheel 3 of the first pair of grinding wheels is opposite to the lower grinding wheel 3 of the second pair of grinding wheels;

[0043] Horizontal 90° steering: through the automatic steering machine arranged between the first grinding device and the second grinding device, the ...

Abstract

The invention discloses a novel method for removing porthole flashing of a PCB. The novel method comprises the following steps: first-time board grinding: putting the PCB after drilling in a first board grinding device for carrying out first-time board grinding; horizontal 90-degree steering: carrying out 90-degree horizontal rotation on the PCB after the first-time board grinding; and second-time board grinding: putting the PCB after horizontal 90-degree steering into a second board grinding device for carrying out second-time board grinding. According to the novel method, the effect of removing the porthole flashing is good, the grinding of a copper surface is uniform, the quality of the PCB is guaranteed, the process is simplified, and the whole operation process is in automatic operation, so that manual carrying actions can be reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of PCB board processing, and relates to a novel method for removing orifice drape on a PCB board. Background technique [0002] The traditional method of removing the edge of the PCB hole usually uses manual grinding after drilling or grinding with an abrasive belt grinder. This method has problems such as cumbersome operations, long process, poor effect of removing the edge of the hole, and uneven polishing of the copper surface. ;The traditional PCB board production process is mostly to remove the holes after drilling, and to grind the board before sinking copper. Reduced the labor intensity of employees. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a novel method for removing the edge of the orifice of the PCB, so that the effect of removing the edge of the orifice is good, the copper surface is polished evenly, the quality of the...
