detailed description

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

Fig. 1 shows a flow chart of a target parameter processing method according to an embodiment of the present invention, including:

Step S10, determining the coordinates of each target on the jigsaw puzzle;

Step S20, determining the parameters of each target according to the coordinates, wherein the parameters of each target include the distance between a target on the jigsaw puzzle and other targets on the jigsaw puzzle, that is, automatic measurement of target parameters is realized;

Step S30, embedding the parameter into the item of the work order of the PCB production line.

The method can be realized by computer programming, so that the coordinates of the target can be automatically measured, and automatically embedded into the PCB production software, thereby realizing the automatic processing of the target parameters, thereby helping to improve the efficiency of PCB production.

Preferably, the jigsaw puzzle is a rectangle with targets in at least two corners, and the targets on the same side are parallel to the side, step S10 includes:

Set the coordinates of the lower left vertex of the jigsaw puzzle to (0, 0), the lower side of the jigsaw puzzle is the positive semi-axis of the X axis, the left side of the jigsaw puzzle is the positive semi-axis of the Y axis, and the coordinates of the upper right vertex of the jigsaw puzzle are (X _max , Y _max );

Get the coordinates of the current target as (X _1-n , Y _1-n );

The position of the current target is determined by coordinate calculation.

Fig. 2 shows a schematic diagram of determining target parameters according to an embodiment of the present invention. In the jigsaw puzzle of Fig. 2, the four corners respectively have targets (X _1-1 , Y _1-1 ), (X _1-2 , Y _1-2 ), (X _1-3 , Y _1-3 ) and (X _1-4 , Y _1-4 ). In the related art, when the coordinates (X _1-n , Y _1-n ) of a target are obtained, the position of the target can only be determined through human eye observation, which is obviously prone to errors. In this preferred embodiment, the position of the current target is determined by coordinate calculation, which can be easily realized by computer programming, so that it can automatically determine which corner the target is located on.

Preferably, determining the position of the current target through coordinate calculation includes:

Set X _m =1/2*X _max , Y _m =1/2*Y _max ;

When X _1-n <X _m and Y _1-n <Y _m , determine that the current target is located in the lower left corner of the jigsaw puzzle, and record (X _1-n , Y _1-n ) as (X _1-1 , Y _1-1 );

When X _1-n >X _m and Y _1-n <Y _m , determine that the current target is located in the lower right corner of the jigsaw puzzle, and record (X _1-n , Y _1-n ) as (X _1-2 , Y _1-2 );

When X _1-n <X _m and Y _1-n >Y _m , then determine that the current target is located in the upper left corner of the jigsaw puzzle, and record (X _1-n , Y _1-n ) as (X _1-3 , Y _1-3 );

When X _1-n >X _m and Y _1-n >Y _m , determine that the current target is located in the upper right corner of the jigsaw puzzle, and record (X _1-n , Y _1-n ) as (X _1-4 , Y _1-4 ).

The above coordinate calculation process first obtains the center point coordinates (X _m , Y _m ) of the jigsaw puzzle, and then uses the comparison between the current target coordinates and the center point coordinates to determine the current target position. The calculation process is relatively simple, and it is easy to use the computer programming to achieve.

Preferably, step S20 includes at least one of the following steps:

Determine the distance X ₁ =X _1-2 -X _1-1 between the target in the lower left corner and the target in the lower right corner;

Determine the distance between the target in the lower left corner and the target in the upper left corner Y ₁ =Y _1-3 -Y _1-1 ;

Determine the distance X ₂ =X _1-4 -X _1-3 between the target in the upper left corner and the target in the upper right corner;

Determine the distance Y ₂ =Y _1-4 −Y _1-2 between the target in the upper right corner and the target in the lower right corner.

The calculation process is relatively simple and can be easily realized by computer programming.

Preferably, step S30 includes:

Create a text file, which contains parameters;

Extract the parameters from the text file, which realizes the automatic capture of the target parameters;

Embedding the extracted parameters into the corresponding items of the work order realizes the automatic embedding of the target parameters.
