When a round silicon rod is required to be fed, firstly, an L-shaped round rod feeding frame is placed in a mode that a long arm of the round rod feeding frame is transversely placed; and then, horizontally placing the round silicon rod on the round rod supporting mechanism to perform material detection. For the subsequent need for transporting and cutting the silicon rod, the length of the silicon rod needs to be measured. The distance between the position of the length measurement reference surface and the initial position of the round bar clamping block is determined. Under the condition that the material is detected to be the material, the round rod clamping block starts to move from the round rod clamping block to the end face of one side of the pushing silicon rod until the base surface of the length side beam is propped up under the drive of the round rod clamping cylinder, the clamping block displacement measuring device measures the displacement of the round rod clamping block, and then the round rod processing unit calculates the length of the round silicon rod.

and the transfer driving assembly is used for driving the upper clamping jaw assembly to move up and down in the vertical direction relative to the lower clamping jaw assembly and driving the upper clamping jaw assembly and the lower clamping jaw assembly to move up and down synchronously. The up-and-down movement direction of the upper clamping jaw assembly and the lower clamping jaw assembly is a vertical direction, namely a Z direction of the silicon rod cutting system.

The transfer driving assembly comprises an upper clamping jaw transfer driving device which is respectively fixed with the lower clamping jaw assembly and the upper clamping jaw assembly and drives the upper clamping jaw assembly to move up and down relative to the lower clamping jaw assembly;

and the lower clamping jaw transferring driving device is respectively fixed with the upper and lower material clamping jaw frames and the lower clamping jaw assemblies and drives the lower clamping jaw assemblies, the upper clamping jaw assemblies and the upper clamping jaw transferring driving device to move up and down synchronously.

Through transporting the drive assembly, realized two functions, firstly go up the clamping jaw subassembly and can make the distance between clamping jaw subassembly and the lower clamping jaw subassembly grow alone upward movement, can also make the distance between clamping jaw subassembly and the lower clamping jaw subassembly reset and diminish alone downward movement. Thus, when the silicon rod or square rod is short, the distance between the upper clamping jaw assembly and the lower clamping jaw assembly may not need to be adjusted, and only the lower clamping jaw assembly is needed to clamp; when the silicon rod or the square rod is longer, the distance between the upper clamping jaw assembly and the lower clamping jaw assembly can be kept unchanged, and the upper clamping jaw assembly and the lower clamping jaw assembly can clamp simultaneously; when the silicon rod or the square rod is very long, the distance between the upper clamping jaw assembly and the lower clamping jaw assembly can be increased, and the silicon rod or the square rod can be stably clamped during transferring. Secondly, the transfer device clamps the silicon rod or the square rod, when the transfer device needs to be lifted for rotation, the distance between the upper clamping jaw assembly and the lower clamping jaw assembly is kept unchanged, and the transfer device synchronously moves upwards, namely, the clamped silicon rod or square rod is lifted for transferring the silicon rod or square rod; after the silicon rod or the square rod is transferred in place, the distance between the upper clamping jaw assembly and the lower clamping jaw assembly is kept unchanged, and the silicon rod or the square rod synchronously moves downwards, namely, the clamped square rod or the square rod is put down.

The combination mode of transporting the pneumatic cylinder and transporting the cylinder for it is less to transport the structure of drive assembly, can make transfer device's overall structure less.

Specifically, when a shorter silicon rod is clamped, the transfer cylinder is reset and retracted, and the transfer pneumatic-hydraulic cylinder extends out; when the shorter silicon rod is clamped, the transfer cylinder and the transfer pneumatic-hydraulic cylinder extend out simultaneously.

If the length of the silicon rod is 150mm or more and 400mm or less, only the lower clamping jaw assembly clamps the round silicon rod before cutting or the square rod after cutting, and then the transfer pneumatic-hydraulic cylinder acts to lift the silicon rod or the square rod for transfer.

When the length of the silicon rod is more than 400mm and less than or equal to 850mm, the distance between the upper clamping jaw assembly and the lower clamping jaw assembly is kept unchanged, and the upper clamping jaw assembly and the lower clamping jaw assembly are jointly involved in clamping the round silicon rod before cutting or the square rod after cutting.

When the length of the silicon rod is greater than 850mm, the upper clamping jaw assembly and the lower clamping jaw assembly jointly participate in clamping the round silicon rod before cutting or the square rod after cutting, wherein the upper clamping jaw assembly can move up and down in the vertical direction of the upper and lower material clamping jaw frames due to the action of the transfer cylinder, and the clamping action is carried out on the round silicon rod before cutting or the square rod after cutting, which are suitable for different lengths.

and judging that the silicon rod does not meet the preset silicon rod standard when any one of four included angles formed by the four cutting straight lines is smaller than 85 degrees or larger than 95 degrees, namely the crystal line of the silicon rod is too inclined. Even after cutting, square bars cannot be obtained, and cutting is not performed subsequently.

Like this, silicon rod detection subassembly and silicon rod detection processing unit cooperate, judge once whether the silicon rod satisfies the silicon rod standard of predetermineeing, avoided cutting the silicon rod that does not accord with the silicon rod standard of predetermineeing, improved efficiency, reduced the waste of time.

The silicon rod detection processing unit is also used for:

Judging the actual eccentricity of the silicon rod arranged on the silicon rod supporting mechanism relative to the center of the silicon rod supporting mechanism, and adjusting the position of the silicon rod when the actual eccentricity exceeds a preset allowable eccentricity range;

the clamping jaw synchronous reverse movement assembly is used for driving the left clamping jaw and the right clamping jaw to synchronously and reversely move to be close to and far away from each other.

Therefore, the left clamping jaw and the right clamping jaw can conveniently clamp the silicon rod at the same time, and the silicon rod is loosened at the same time.

Specifically, as shown in fig. 3D and 3E, the jaw synchronization reverse motion assembly includes:

a transferring clamping jaw cylinder 351, wherein a cylinder body of the transferring clamping jaw cylinder 351 is fixed with the transferring clamping jaw fixing plate 331;
