Abstract

Moreover, the block materials are uneven, there are many powder materials, and the waste is serious.
[0003] Recently, some manufacturers have adopted silicon material heating equipment to heat silicon materials, and then used water to rapidly cool down the heated silicon materials.

It can be understood that the guide rail and the rack are arranged on the frame at intervals along the second direction x. When the driving assembly 50 is a screw drive, the screw and the guide rail are arranged on the frame at intervals along the second direction x.

For example, when the drive assembly 50 is a gear rack, along the first direction z, two stoppers are respectively fixed to opposite ends of the rack, and the gear rolls along the rack between the two stoppers to reduce the risk of the gear being separated from the rack. For example, when the drive assembly 50 is a screw drive, along the first direction z, two stoppers are respectively fixed to opposite ends of the screw, and the screw mounting seat is disposed between the two stoppers, thereby reducing the risk of the screw mounting seat being separated from the screw.
[0073] In some embodiments, Figure 8As shown, in order to facilitate the material carrier 20 to move to the accommodating space 41 of the support frame 40 through the second opening 102 and to facilitate the material carrier 20 to enter the feed port, the material carrier 20 is movably arranged on the support frame 40, and the material carrier 40 can move relative to the support frame 40 along the second direction x. Specifically, the feeding mechanism 100 includes a sliding assembly 70, and the sliding assembly 70 includes a slide rail 71 and a pulley 72. The slide rail 71 is arranged at the bottom of the accommodating space 41 of the support frame 40 along the second direction x, and the pulley 72 is arranged at the bottom of the material carrier 20, and the pulley 72 is slidably connected to the slide rail 71. Specifically, the pulley 72 is rotatably connected to the bottom of the material carrier 20, for example, a groove is provided at the bottom of the material carrier, and a shaft is connected in the groove, and the pulley 72 is accommodated in the groove and penetrated on the shaft, and at least a portion of the pulley extends out of the groove so that the pulley 72 is connected to the slide rail 71.
[0074] It can be understood that the number of the slide rails is at least 2, and the two slide rails are arranged at a distance at the bottom of the accommodation space. A plurality of pulleys can be arranged on one slide rail.

Specifically, the stopper 80 is arranged in the accommodation space 41 and close to the third opening 103, and the stopper 80 is used to limit the material carrier 20 to prevent the material carrier 20 from leaving the accommodation space 41.
[0076] In some embodiments, Figure 8 As shown, the feeding mechanism includes a detection member 90, and the detection member 90 includes a first detection member 91 and a second detection member 92.

The first detection member 91 is configured to send a first signal to the controller when the material carrier 20 enters the feed port through the first opening 101, so that the controller controls the driving source 51 to drive the support frame 40 to move from the first opening 101 to the second opening 102, so that the first baffle 30 can close the first opening 101, and the support frame 40 waits for loading a new material carrier 20 (carrying silicon material). The second detection member 92 is disposed in the accommodating space 41 and is disposed near the third opening 103. The second detection member 92 is electrically connected to the controller. The second detection member 92 is configured to send a second signal to the controller when a new material carrier enters the accommodating space 41 through the second opening 102 and abuts against the stop member 80, so that the controller controls the driving source 51 to drive the support frame 40 to move from the second opening to the first opening, so as to push the material carrier 20 carrying the silicon material into the feed port, and repeat this cycle.
[0077] In some embodiments, Fig. 9 As shown, the feeding mechanism 100 further includes a second baffle 30a, which is used to close the third opening 103, further reducing the heat loss of the silicon material heating device, and also reducing the pollution of the parts installed in the frame 10.

The second baffle 30a is configured to close the third opening 103 when the support frame 40 moves to the second opening 102, and to open the third opening 103 when the support frame 40 moves to the first opening 101. At this time, the second baffle 30a can be driven by a driving device, and at the same time, the driving device is electrically connected to the controller, so that the controller controls the driving device to drive the second baffle 30a to close the third opening 103 in response to the first signal, or the controller controls the driving device to drive the second baffle 30a to open the third opening 103 in response to the second signal. Alternatively, in another embodiment, one end of the second baffle 30a is rotatably connected to the frame 10, and the other end of the second baffle 30a is configured to open / close the third opening 103, so that an external device can extend into the accommodating space 41 through the third opening 103 to push the material carrier 20 into the feed port. For example, when the support frame 40 moves to the second opening 102, the second baffle 30a closes the third opening 103; when the support frame 40 moves to the first opening 101, the external device can push the second baffle 30a to open the third opening 103.
