[0009] From the above description, the beneficial effects of the present application are that, through the arrangement of the first clamping mechanism 32 and the second clamping mechanism 33 of the transfer assembly 3 on the fixed frame 31, the silicon rod clamping mechanism, the edge skin clamping mechanism and the half rod clamping mechanism can be avoided to be arranged separately, different clamping modes can be switched by rotation, the equipment structure is simplified, and the space arrangement is optimized; at the same time, the rotation arrangement of the transfer assembly 3 can also match the lateral arrangement of the loading and unloading frames to perform the loading and unloading operation.

[0010] Further, the feeding and discharging rack comprises a silicon rod feeding rack 4, the silicon rod feeding rack 4 comprises a first feeding rack 41, a traction mechanism and a pull rope sensor 47, the first feeding rack 41 is provided with a first slide 411, the fixed end of the pull rope sensor 47 is connected with the first feeding rack 41, and the movable end of the pull rope sensor 47 is connected with the traction mechanism; the traction mechanism is movably arranged on the first slide 411.

[0011] As can be known from the above description, the silicon rod is transferred to the designated feeding position by moving the traction mechanism along the first slide 411, and the length of the silicon rod is measured during the movement of the silicon rod by using the pull rope sensor 47.

[0012] Specifically, first, the distance between the fixed end of the pull rope sensor 47 and the position of the end of the silicon rod when the silicon rod moves to the designated feeding position (one end of the pull rope sensor 47) is determined, which is the first distance 4100. Generally, the designated feeding position is a fixed position, so the first distance 4100 is a fixed distance; then, the distance between the fixed end of the pull rope sensor 47 and the initial position of the traction mechanism is determined, which is the second distance 4110. Similarly, the second distance 4110 is a fixed distance; after the silicon rod is moved to the designated feeding position by the traction mechanism, the movable end of the pull rope sensor 47 is moved due to the displacement of the traction mechanism to obtain the moving distance of the pull rope sensor 47, that is, the third distance 4120. Then, the final length of the silicon rod is the first distance 4100 minus the second distance 4110 minus the third distance 4120.

[0014] As can be known from the above description, the other end of the silicon rod is limited by the arrangement of the blocking mechanism 410; during feeding, the silicon rod enters from the feeding end of the first slide 411, and then is pulled by the traction mechanism until the whole silicon rod enters the first slide 411, and then the blocking mechanism 410 is lifted out of the first slide 411, the silicon rod is pushed to the blocking mechanism 410 by the traction mechanism, and finally the feeding limitation of both ends of the silicon rod is realized and the silicon rod is in the designated feeding position.

[0015] Further, the feeding and discharging rack comprises a rod discharging rack 5, the rod discharging rack 5 comprises a second feeding rack 51 and a pressing mechanism 52, the second feeding rack 51 is provided with a second slide 511, and the pressing mechanism 52 is detachably arranged on the second feeding rack 51 and downwardly pressed towards the second slide 511.

[0019] Further, the third slide 611 is provided with a centering guide wheel 612 on both sides along the length direction; and the third slide 611 is provided with a limiting support 613 on both sides.

[0020] As can be known from the above description, based on the arc surface of the flash, the centering guide wheel 612 can be used to stably place the flash in the middle of the third slide 611, and the limiting support 613 is used to avoid shaking and falling out of the flash when placed.
