With the continuous promotion of green energy, solar power generation has become the most important renewable energy source besides hydro-power generation and wind power generation, and in the solar power generation technology, perovskite solar cells have considerable influence. In the process of processing perovskite solar cells, the laser scribing apparatus 100 is used to scribe and divide the multi-layer coating on the perovskite thin film cells to divide the whole cell sheet into equidistant subcells.

Specifically, the bearing component 11 is used for bearing the battery piece, the bearing component 11 can be abutted with the battery piece to bear the battery piece, the bearing component 11 can also form an air film with the battery piece to bear the battery piece, and the bearing component 11 can bear the battery piece, so that the application is not particularly limited.

During processing of the battery piece, the battery piece moves back and forth along the Y axis. The processing assembly 13 is used for driving the battery piece to move along the Y-axis direction. In particular, there are many constructions of the processing assembly 13. In one embodiment, the processing assembly 13 includes a motor and a roller that drives the movement of the battery plate. In another embodiment, the processing assembly 13 includes a conveyor belt and a motor, and the battery plate is moved by the conveyor belt. It will be appreciated that in some embodiments, the carrier assembly 11 and the processing assembly 13 may be the same structure that is capable of both carrying and driving the movement of the battery cells.

The first laser head 21 may be an infrared laser head. The second laser head 23 may be a green laser head. There are a number of ways in which the flight path assembly 25 can be moved in the X-axis direction: in one embodiment, the laser mechanism 20 includes a guide rail and a linear motor, the flying light path component 25 is disposed on the guide rail, and the linear motor drives the flying light path component 25 to move; in another embodiment, the laser mechanism 20 includes a ball screw on which the flying optical path assembly 25 is disposed, and a motor that drives the ball screw to rotate to drive the flying optical path assembly 25 to move in the X-axis direction. It should be noted that, in the process of performing laser scribing on the battery piece by the laser scribing device 100, the processing component 13 drives the battery piece to move along the Y-axis direction, and the flying light path component 25 reflects the first light beam and the second light beam to the battery piece, so as to scribe the battery piece, and the scribing line extends along the Y-axis direction; after the scribing is completed once, the flying light path assembly 25 is moved to the desired scribing position along the X-axis direction, and the processing assembly 13 continues to drive the battery piece to move along the Y-axis direction, and the scribing process is repeated, thereby scribing a plurality of parallel lines on the battery piece.

It should be noted that, the included angle between the first light beam reflected by the light path assembly 25 and the Z-axis direction may be 0 degrees, 5 degrees, 10 degrees, 30 degrees, 40 degrees, etc., which are not specifically recited in the present application, and the angle between the light path assembly 25 and the first light beam reflected by the light path assembly may be adjusted according to the spatial layout of the laser scribing apparatus 100, which is not specifically limited in the present application.

In the embodiment of the present utility model, referring to fig. 1, 2 and 3, the flying light path component 25 is disposed below the carrying mechanism 10, and the flying light path component 25 includes a reflecting prism 251, the reflecting prism 251 can reflect a first light beam along the X-axis direction to a second light beam along the Z-axis direction, and the reflecting prism 251 can reflect a second light beam along the X-axis direction to the Z-axis direction.

Thus, the first laser head 21 and the second laser head 23 are not required to be arranged above or below the battery piece, so that the battery piece can be scored by the first light beam and the second light beam along the Z-axis direction, the height of the laser scoring device 100 is effectively reduced, and a better space utilization effect is achieved.

It is understood that, in other embodiments, the reflecting prism 251 may reflect the first light beam and/or the second light beam along the X-axis direction to a direction having an angle along the Z-axis direction, for example, having angles of 10 °, 20 °, 30 ° and the like along the Z-axis direction, which is not particularly limited herein. It should be noted that, the reflecting prism 251 reflects the first light beam and/or the second light beam along the X-axis direction to the Z-axis direction, so that it is more convenient to align the first light beam and/or the second light beam with the battery piece, i.e. the reflecting prism 251 is located right below the scribing position required by the battery piece.

It should be noted that the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

During scribing, if the battery piece is not flat, i.e. the battery piece is warped, the focal position of the first beam or the second beam may need to be adjusted accordingly.

To solve the above problem, further referring to fig. 2 and 3, the flying optical path assembly 25 further includes a first focusing mirror 253 and a second focusing mirror 255, wherein the first light beam is focused by the first focusing mirror 253 and then is incident on the reflecting prism 251 along the X-axis direction, the second light beam is focused by the second focusing mirror 255 and then is incident on the reflecting prism 251 along the X-axis direction, and the reflecting prism 251 can move along the X-axis direction.

In this way, the first focusing mirror 253 can focus the first light beam to ensure that the focus of the first light beam is located on the battery piece during scribing, and the second focusing mirror 255 can focus the second light beam to ensure that the focus of the second light beam is located on the battery piece during scribing; in addition, the reflecting prism 251 can move in the X-axis direction, and since the focal length of the first focusing mirror 253 is unchanged, the focal point and the reflecting prism 251 are moved together when the distance between the reflecting prism 251 and the first focusing mirror 253 is adjusted, thereby achieving the effect of adjusting the focal point position of the first light beam, and similarly, the focal point and the reflecting prism 251 are moved together when the distance between the reflecting prism 251 and the second focusing mirror 255 is adjusted, thereby achieving the effect of adjusting the focal point position of the second light beam.

Specifically, for ease of understanding, the following description is given by way of example. In one embodiment, the focal length of the first focusing mirror 253 is 500 mm, and the distance from the first focusing mirror 253 to the reflecting prism 251 in the X-axis direction is 200 mm, so that the distance from the reflecting prism 251 to the battery plate in the Z-axis direction is 300 mm, so that the focal point of the first light beam is on the battery plate. When the distance from the reflecting prism 251 to the battery plate is 250 mm, the reflecting prism 251 may be moved by 50 mm along the X-axis direction in a direction away from the first focusing mirror 253, that is, when the distance from the first focusing mirror 253 to the reflecting prism 251 is 250 mm, the distance from the reflecting prism 251 to the battery plate is 250 mm, that is, the focal point of the first light beam. Therefore, by moving the position of the reflecting prism 251 in the X-axis direction, the adjustment of the focal position of the first light beam is realized, so that the device is suitable for battery pieces with different heights, and the battery pieces with different requirements on the focal position can be conveniently processed. The second light beam is the same, and detailed description is omitted in this application.

In this way, the fourth mirror 259 and the first focusing mirror 253 can move together along the Y-axis direction, so as to adjust the position of the first light beam in the Y-axis direction, and adapt to the requirement of more scribing positions.

It will be appreciated that the flying light path assembly 25 may further include other mirrors to facilitate adjusting the position of the second light beam in the Y-axis direction, which is not described in detail herein.
