[0035] Embodiment 1

[0036] like Figure 2 and Figure 6 As shown, this embodiment provides a silicon rod pushing device 1, which includes a support assembly 11 and a pushing mechanism 12.

[0039] The roller pushing unit 1222 includes a support 12221, an articulated shaft 12222 and at least one roller 12223, the roller 12223 is sleeved on the articulated shaft 12222, the articulated shaft 12222 is vertically oriented on the connecting plate 1221 through the support 12221, the articulated shaft 12222 is rotatably connected to the support 12221, the rolling surface of the roller 12223 abuts against the pushing block 1223, and the side of the pushing block 1223 close to the silicon rod 3 is an inclined surface.

[0042] like Figure 3 and Figure 6 As shown, the driving assembly 123 includes a first linear guide rail 1231, a pushing slide 1232 and a pushing connecting frame 1233. The first linear guide rail 1231 is located in the through groove 13 of the supporting assembly 11 and is arranged along the length direction of the supporting assembly 11. The pushing slide 1232 is slidably connected to the first linear guide rail 1231, and the pushing slide 1232 is connected to the pushing seat 121 through the pushing connecting frame 1233.

[0043] like Figure 3 and Figure 4 As shown, the pushing mechanism 12 also includes a sensor assembly 124, and the sensor assembly 124 includes a connected sensor unit 1241 and a driving member 1242. The pushing seat 121 is provided with a through hole along the length direction of the support assembly 11; the driving member 1242 is located on the side of the pushing connecting frame 1233 away from the silicon rod 3, and the driving member 1242 drives the sensor unit 1241 to move in the through hole to abut against the apex of the head cone.

[0045] Working principle:

[0046] Before the silicon rod 3 is cut, the silicon rod 3 is placed on the support assembly 11 of the silicon rod pushing device 1, with the head cone of the silicon rod 3 facing backwards and away from the cutting head 2 of the cutter. When the driving assembly 123 drives the pushing seat 121 to move along the length direction of the supporting assembly 11 toward the head cone of the silicon rod 3, after the pushing block 1223 contacts the head cone of the silicon rod 3, the pushing slide 1232 continues to move along the first linear guide rail 1231, and the roller 12223 on the roller pushing unit 1222 rotates to push the pushing block 1223 abutting against its rolling surface, and the limiting connecting column 1224 connected to the pushing block 1223 slides along the sliding groove 1225, at which time the pushing block 1223 deflects, so that the inclined surface of the pushing block 1223 contacts the inclined surface of the head cone of the silicon rod 3. Then, the driving assembly 123 continues to drive the pushing seat 121 to move along the length direction of the supporting assembly 11 until the front end of the silicon rod 3 hits the limiting block and stops.

[0047] The motor torque of the push slide 1232 in the driving component 123 increases. When it reaches a certain set value, the motor in the driving component 123 stops applying force and feeds back to the sensor component 124. The slider 12422 in the driving member 1242 drives the sensor unit 1241 to move forward. When the sensor unit 1241 hits the top of the head cone, it stops. Since the rod length, front cone length, and head cone length of the silicon rod 3 are known in advance, the sensor unit 1241 records the reference position coordinates of the current silicon rod 3 and feeds back to the system.

[0048] Then, the limit stopper in front of the silicon rod 3 is removed, and the control system calculates the distance from the silicon rod 3 to the cutting head 2. The driving assembly 123 then drives the pushing seat 121 to continue pushing the silicon rod 3 to the cutting position and stop, thus completing the tool alignment.

[0049] Embodiment 2

[0050] like Figure 1 As shown, this embodiment provides a cutting machine, including the silicon rod pushing device 1 in the first embodiment, and also including a cutting head 2, the cutting head 2 is arranged above the front side of the support component 11, the pushing mechanism 12 moves along the length direction of the support component 11 to abut and push the head cone of the silicon rod 3 to a preset position, and then the cutting head 2 cuts the silicon rod 3.

[0051] Since the silicon rod pushing device 1 in the cutter is provided with the pushing mechanism 12, the knife alignment of the silicon rod 3 is realized, that is, the silicon rod 3 is pushed to the cutting position for cutting, thereby improving the efficiency and reducing the labor intensity.
