And step 206, acquiring the matching parameters of each screw hole and the reference screw hole in the standard structure layout list.
Referring to fig. 3, it can be seen that the process of obtaining matching parameters of any screw hole in the standard structure layout list and the reference screw hole may include the following sub-steps:
When any screw hole in the standard structure layout list moves to the reference screw hole, a moving parameter is corresponding to the screw hole, and each structural element in the standard structure layout list is moved according to the moving parameter, namely, each structural element in the standard structure layout list is moved once according to any moving parameter.

Illustratively, after each structural element in the standard structural layout list is moved by a1 units in the direction of the horizontal axis and a2 units in the direction of the vertical axis, the number of coincidences of the structural elements in the standard structural layout list and the structural elements on the printed circuit board to be checked is a1, that is, the number of coincidences of the structural elements corresponding to the screw holes a is obtained as a1, and then the numbers of coincidences of the structural elements corresponding to the screw holes B and the screw holes C are obtained as B1 and C1.
Sub-step 2063, determining the number of coincidences as the matching parameter of any screw hole and the reference screw hole.
And taking the superposition number of the structural elements after each structural element in the standard structural layout list moves according to the movement parameters as matching parameters.
Illustratively, the number of coincidences a1 is taken as a matching parameter of the screw hole a and the reference screw hole, the number of coincidences B1 is taken as a matching parameter of the screw hole B and the reference screw hole, and the number of coincidences C1 is taken as a matching parameter of the screw hole C and the reference screw hole.
And step 207, determining the screw hole with the maximum matching parameter in the standard structure layout list as a target screw hole.
And when the number of the coincidences is the maximum, determining the screw holes in the corresponding standard structure layout list as target screw holes and matching the target screw holes with the reference screw holes.
Illustratively, if the matching parameter a1 of the screw hole a and the reference screw hole is maximum, the screw hole a is determined as the target screw hole.
And step 208, moving each structural element in the standard structure layout list according to the moving parameters of the target screw hole to the reference screw hole.
And moving each structural element in the standard structure layout list according to the movement parameters corresponding to the target screw holes.
Illustratively, each structural element in the standard structural layout list is moved according to the movement parameters a1 and a2 corresponding to the screw hole A.
And step 209, comparing each structural element in the printed circuit board to be checked with the structural elements in the standard structure layout list to obtain a comparison result.
Comparing each structural element in the printed circuit board to be checked with the structural element at the corresponding position of the standard structure layout list, checking whether the structural element in the printed circuit board to be checked is correct (including the comparison of whether the angle of each vertical terminal in the vertical terminal class is correct), then comparing each structural element in the standard structure layout list with the structural element in the printed circuit board to be checked, checking whether the structural element in the printed circuit board to be checked is missing, wherein the comparison result can include whether the structural element on the printed circuit board to be checked is correct and whether the structural element is missing.
When the printed circuit board to be checked is large in size, the screw holes in the middle positions (positions corresponding to four corners of the printed circuit board to be checked) can be changed into positioning holes, namely the screw holes in the middle positions correspond to the positioning holes in the same positions on the standard structure layout list, the comparison result can be output incorrectly, and an operator can judge the incorrect comparison result according to the comparison result.
The obtained comparison result may be in a text format (i.e., txt format), and the comparison result may include: the position or angle of a certain vertical terminal in the vertical terminal class is incorrect, the position of a screw hole is incorrect, a screw hole or a positioning hole is lacked, and the position of each structural element is correct.
