Referring to fig. 11-12, fig. 11 is a schematic diagram of a copper foil in an XY physical coordinate system; fig. 12 is a schematic diagram of an image acquired by the first visual positioning detection assembly.

In some embodiments, the principle of moving the first laser coding assembly to the coding position set in the control device is as follows: the first laser coding assembly and the first visual positioning detection move synchronously and are fixed in relative position, so as shown in fig. 11, a pre-established physical coordinate system for the roll-to-roll double-sided laser coding system is adopted here, the relative position information of the laser emitting position a (X1, Y1) of the first laser coding assembly and the central position B (X2, Y2) of the camera of the first visual positioning detection assembly can be known through calibration, and the relative position information is stored by the control device. Every section that plane supporting platform bore sets for length all is equipped with the positioning mark on the copper foil, first visual positioning detection subassembly basis positioning mark obtains first locating information, controlling means basis first locating information, relative position information and the coding position information that sets for among the controlling means obtain first laser code printing subassembly with the copper foil waits to code the first relative position information of the first target location, will first laser code printing subassembly moves to the sign indicating number position of beating of settlement.

And the positioning mark is a mark preset at a preset position on each section of copper foil. In some embodiments, when the first visual positioning detection assembly photographs the copper foil, if the imaging position of the positioning mark in the image photographed by the first visual positioning detection assembly is located at the image center position, it indicates that the first laser coding assembly is facing the set coding position at this time.

Generally, the first laser coding assembly is not directly opposite to the set coding position, so that when the first visual positioning detection assembly acquires the first positioning information, the imaging position of the positioning hole is generally not at the center of the image. For example, as shown in fig. 12, the imaging position C (x3, Y3) of the positioning hole is shifted from the image center position D (x4, Y4), the image coordinate system is different from the physical coordinate system in units, the physical coordinate system Y axis is decreased downwards, and the image coordinate system Y axis is increased downwards, so that the physical relative position information that the first laser coding assembly and the first visual positioning detection need to be moved relative to the set coding position can be obtained according to the virtual relative position information of the imaging position of the positioning hole and the image center position in order to make the imaging position of the positioning hole be the image center position. In this case, the relative position information between the first positioning information acquired by the first visual alignment detection unit and the laser emission position a (X1, Y1) of the first laser coding unit should be: (X1, Y1) - (X2, Y2) - ((X3, -Y3) - (X4, -Y4)) P, P being a coefficient for converting the image coordinate system into a physical coordinate system.

Similarly, the relative position information between the first laser code printing assembly and the first code reading gun can be obtained, and after the first laser code printing assembly prints codes, the control device controls the first moving mechanism to move the first code reading gun to the code printing position to read the information codes according to the code printing position and the relative position information between the first laser code printing assembly and the first code reading gun.

Similarly, the relative position information between the second laser coding assembly and the second visual positioning detection assembly can be obtained, the relative position information between the second laser coding assembly and the second code reading gun can be obtained, so that the control device can control the second moving mechanism to move the second laser coding assembly to the set coding position for coding, and the second code reading gun can move to the coding position for reading the information code.
