During the processing of silicon wafers or solar cells, a cassette handling mechanism is required to pick up and move the cassette to move the cassette to each processing station. The existing cassette handling mechanisms usually pick up the cassette by means of clamping. In the specific application process, this method may cause the cassette to accidentally fall due to insufficient clamping force, resulting in poor safety.
[0031] Therefore, the present application proposes a cassette handling mechanism.

A pressing plate 31 is vertically fixed to the end of the piston rod of the cylinder 30. The cylinder 30 is configured to drive the pressing plate 31 to move so as to press the wafers in the cassette 20.
[0036] It can be seen that after the cassette 20 is filled with wafers, the cylinder 30 can be used to drive the pressing plate 31 to move to press the wafers, so that the wafers will not shake during the movement of the cassette 20.
[0037] Please refer to Figure 2 As shown, as an implementation manner, the cassette 20 includes a support member 23, a first limiting member 24 and a second limiting member 25, wherein: an inclined surface 230 for supporting the wafers is formed on the support member 23.
