The difficulty of the hole 10. After the respective conductive strips 7 are selected one by one to insert the slots 10, the respective conductive strips 7 are inserted into the slots 10 (step 110).

Compared with the prior art, the present invention uses the camera module to pre-acquire the size of each slot image of the corresponding slot in the image measurement manner, and the present invention actually measures the size of each conductive strip to obtain the size of each conductive strip. The selected conductive strips can be selected through the above dimensions to be inserted into the slots, thereby reducing the difficulty in inserting the conductive strips into the slots, thereby improving the mounting efficiency of the conductive strips. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
