Problems solved by technology

[0002] In the production of PNL, when drilling the L groove, first divide the T to drill two grooves without direction order, and then drill the burrs at the corners. This drilling method cannot eliminate all burrs, and there are still burrs in a considerable proportion of the corners. , the remaining burrs are manually removed, which increases the cost, and it is difficult to ensure that the board with burrs will not flow to the next process, resulting in unpredictable scrapping of the subsequent process

[0041] Based on the method for eliminating burrs at the corners of L-shaped special-shaped slots provided in the first embodiment of the present application, the second embodiment of the present application proposes another method for eliminating burrs at the corners of L-shaped special-shaped slots. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0042] The second embodiment of the present invention will be further described below in conjunction with the drawings and implementation methods.

[0043] Please refer to Figure 5-Figure 6 The difference between this embodiment and the first embodiment is that, before the step S1 starts, the plate needs to be placed on the workbench and pressed.

[0044] The workbench includes a base 1, the top side of the base 1 is provided with a placing platform 2, the plate is placed on the placing p...

Abstract

The invention provides a method for eliminating burrs at corners of an L-shaped special-shaped slotted hole. The method for eliminating the burrs at the corners of the L-shaped special-shaped slotted hole comprises the following steps that S1, the intersection circle center of two slots serves as an original point, and a plane coordinate system is established; S2, the position of a corner of the L slot is judged; and S3, slot drilling is carried out, specifically, when the corner of the L-shaped slot is in the first quadrant and the third quadrant, a vertical slot is drilled firstly and then a transverse slot is drilled, and when the corner of the L-shaped slot is in the second quadrant and the fourth quadrant, the transverse slot is drilled firstly, and then the vertical slot is drilled. According to the method for eliminating the burrs at the corners of the L-shaped special-shaped slotted hole, the burrs are eliminated from the mechanism, the link of manually brushing the burrs does not need to be added, the labor cost is saved, and therefore the risk of scrapping is avoided.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a method for eliminating burrs at corners of L-shaped special-shaped slot holes. Background technique [0002] In the production of PNL, when drilling the L groove, first divide the T to drill two grooves, without direction order, and then drill the burr holes at the corners. This drilling method cannot eliminate all burrs, and there are still burrs in a considerable proportion of the corners. , The remaining burrs are manually removed, which increases the cost, and it is difficult to ensure that the board with burrs will not flow to the next process, resulting in unpredictable scrapping of the subsequent process. [0003] Therefore, it is necessary to provide a new method for eliminating the burrs at the corners of L-shaped special-shaped slots to solve the above technical problems. Contents of the invention [0004] The technical problem solved by the invent...
