In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] As Figures 1 - 2 shown, this embodiment provides a solar cell handling device, which mainly includes a base 100, an adjustment seat 400, a support plate 500, a first driving device 200, a second driving device 300, and a handling assembly 600. Among them, the first driving device 200 and the second driving device 300 are arranged on the base 100, and the first driving device 200 is vertically arranged with the second driving device 300. The adjustment seat includes a first adjustment seat 4001 and a second adjustment seat 4002. Both the first adjustment seat 4001 and the second adjustment seat 4002 are movably connected to the base 100, and at least two of the first adjustment seat 4001 and the second adjustment seat 4002 are respectively provided. The first driving device 200 and the second driving device 300 are respectively drivingly connected to the first adjustment seat 4001 and the second adjustment seat 4002. The first driving device 200 can drive the first adjustment seat 4001 to move along the first direction, and the second driving device 300 can drive the adjustment seat to move along the second direction, and the first direction is perpendicular to the second direction. The support plate 500 is arranged on the adjustment seat 400, and a handling assembly 600 is arranged on the support plate 500. The handling assembly 600 is used for handling silicon wafers. It should be noted that the first direction in this embodiment is Figure 2 the X-axis direction in Figure 2 i.e., the width direction of the base 100; the second direction in this embodiment is

[0037] the Y-axis direction in

[0038] The solar cell handling device in this embodiment is arranged between two wafer sorters and is used to transfer wafers from the belt of one sorter to the belt of another sorter. The solar cell handling device further includes a controller (not shown in the figure) and a positioning sensor (not shown in the figure). The positioning sensor can capture the position of the handling component 600 in real time and transmit the captured signal to the controller. The controller controls the first driving device 200 and the second driving device 300 to work, so that the first adjusting seat 4001 moves in the first direction and the second adjusting seat 4002 moves in the second direction, thereby finely adjusting the position of the handling component 600, enabling the handling component 600 to accurately place the wafers on the belt of another sorter, and improving the accuracy and working efficiency of the solar cell handling device in handling wafers. It should be noted that the working principle of monitoring the handling component 600 through the positioning sensor in this embodiment and the controller controlling the first driving device 200 and the second driving device 300 to drive the first adjusting seat 4001 and the second adjusting seat 4002 respectively belongs to the prior art and can be achieved as long as the positioning sensor, the controller, the first driving device 200 and the second driving device 300 are electrically connected. Therefore, this embodiment will not elaborate on this further.

[0039] Specifically, when the solar cell handling device is working normally, the first driving device 200 can drive a first adjusting seat 4001 to move in the first direction, so that the first adjusting seat 4001 can drive the support plate 500 to move in the first direction, and thus the handling component 600 on the support plate 500 can move in the first direction, realizing the fine adjustment of the handling component 600 in the X-axis direction. When fine adjustment of the handling component 600 in the Y-axis direction is required, the second driving device 300 can drive a second adjusting seat 4002 to move in the second direction, so that the second adjusting seat 4002 can drive the support plate 500 to move in the second direction, and thus the handling component 600 on the support plate 500 can move in the second direction, realizing the fine adjustment of the handling component 600 in the Y-axis direction. Of course, the two second adjusting seats 4002 in this embodiment are respectively driven and connected by two second driving devices 300, thereby improving the flexibility of the support plate 500 to move in the second direction.

[0040] When it is necessary to rotate the support plate 500 in the direction of the plane where the first direction and the second direction are located, that is, to rotate along the plane where the X-axis and the Y-axis are located (in this embodiment, the counterclockwise rotation of the support plate 500 is taken as an example), one of the second driving devices 300 pushes one second adjusting seat 4002 to displace in the second direction, the first driving device 200 pushes the first adjusting seat 4001 to displace in the first direction, and the other second driving device 300 pulls the other second adjusting seat 4002 to displace in the direction opposite to the second direction. In this way, the support plate 500 can be rotated counterclockwise, so as to realize the rotation of the handling assembly 600 on the support plate 500 in the horizontal direction, improve the accuracy of the handling assembly 600 in handling or placing wafers, and save costs. It should be noted that the adjustment of the support plate 500 by the first adjusting seat 4001 and the second adjusting seat 4002 in this embodiment is carried out in real time. That is to say, while the handling assembly 600 is handling the wafers, the first driving device 200 and the second driving device 300 respectively adjust the first adjusting seat 4001 and the second adjusting seat 4002 in real time, so as to realize the accurate handling of the wafers by the handling assembly 600.

[0041] As Figures 2 - 3 shown, in this embodiment, the adjusting seat 400 includes a first connecting plate 410 and a first guide rail 420.

Specifically, the two first guide rails 420 close to the first driving device 200 are both arranged along the first direction; the two first guide rails 420 close to the second driving device 300 are both arranged along the second direction. The arrangement of the first guide rail 420 is beneficial to improving the flexibility of the first connecting plate 410 to displace in the first direction or the second direction.

[0042] As Figures 2 - 3 shown, in this embodiment, the adjusting seat 400 includes a second connecting plate 430 and a second guide rail 440. The second guide rail 440 is arranged on the first connecting plate 410, and the second connecting plate 430 is slidably connected to the second guide rail 440. Further, the second guide rail 440 is arranged as at least four. Exemplarily, in this embodiment, the second guide rail 440 is arranged as four for illustration. Specifically, the two second guide rails 440 close to the first driving device 200 are both arranged along the second direction; the two second guide rails 440 close to the second driving device 300 are both arranged along the first direction. The arrangement of the second guide rail 440 is beneficial to improving the flexibility of the second connecting plate 430 to displace in the first direction or the second direction. The first driving device 200 and the second driving device 300 in this embodiment can both be arranged as motors.

[0043] AsFigures 2 - 3 As shown, in this embodiment, a boss 450 is provided on the second connecting plate 430, and the support plate 500 is connected to the boss 450 through a fixing member (not shown in the figure). The fixing member can be set as a bolt, and the setting of the boss 450 is beneficial to improving the convenience of connecting the support plate 500 and the adjusting seat 400.

The settings of the first push rod 210 and the second push rod 310 can improve the stability and reliability of the connection between the first driving device 200 and the second driving device 300 and the adjusting seat 400, and further improve the accuracy of the displacement of the first driving device 200 and the second driving device 300 driving the first adjusting seat 4001 and the second adjusting seat 4002.

[0045] As Figure 1 As shown, in this embodiment, the handling assembly 600 includes a support column 610, a third guide rail 620, a third driving device 630, a connecting arm 640, and a suction cup 650.
