[0034] First embodiment
[0035] Please refer to Figure 3A-Figure 4D The film box is composed of a top plate 21, a bottom plate 22, a side frame 23 and a rear pillar 24. An open frame structure with an opening (located on the side opposite to the rear pillar 24) on one side, and the inner surface of these parts is correspondingly provided with edge Multiple notches are arranged at intervals in the vertical direction to support the wafer.
[0036] The cassette positioning device includes a limit door 31 and a positioning mechanism. Among them, there are two limit doors 31, and they are rotatably connected to the two side frames 23 respectively. By rotating the two limit gates 31 synchronously, both of them can be located at the first position where the wafer in the cassette is blocked, or at the second position where the wafer in the non-blocking cassette is moved. The so-called second position of the wafer in the non-blocking cassette means that when the limit door 31 is at the ...

[0046] Second embodiment
[0047] Compared with the above-mentioned first embodiment, the cassette positioning device provided by the embodiment of the present invention also includes a limit door 31 and a positioning mechanism, and the positioning mechanism also includes an arc-shaped guide rail, a sliding member, and a locking member. The function is the same as that of the above-mentioned first embodiment, and the structure of the arc-shaped guide rail is the same as that of the above-mentioned first embodiment, but the structure of the sliding member and the locking member is different from the above-mentioned first embodiment. Only the differences between this embodiment and the above-mentioned first embodiment will be described in detail below.
[0048] Please refer to Figure 5A-Figure 6B In this embodiment, two first protrusions 214 facing each other are also provided at the middle positions of the respective hole walls of the first positioning hole 212 and the second posi...
