Description

Technical Field

[0001] This utility model relates to the field of silicon workpiece processing technology, specifically a silicon rod half-cutting mechanism. Background Technology

[0002] With the expansion of applications such as photovoltaics, the market demand for half-rod silicon wafers is gradually emerging. Half-rods are usually obtained by cutting finished square rods along their length direction by center-line cutting (i.e., center-sectioning process). The processing flow includes: half-sectioning, which longitudinally cuts the square rod or finished square rod into two half-rods; and half-rod grinding, which performs secondary grinding on the surface of the center-sectioned half-rod to meet the accuracy requirements of subsequent multi-wire cutting.

[0003] The existing semi-start technology for spherical silicon rods has the following bottlenecks: insufficient process coordination, mismatch between the half-slitting operation and the feeding process, resulting in equipment idling and waiting; thus, the cost is high, and the configuration of multiple equipment leads to a large footprint.

[0004] Secondly, the existing cutting station has only one position. When the cutting mechanism is applied to the silicon rod integrated machine, it is insufficient to supply material, causing other parts of the silicon rod integrated machine to wait or run idle. This leads to an increase in the energy consumption and maintenance costs of the silicon rod integrated machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a silicon rod slitting cutting mechanism that prevents the mismatch between the slitting operation and the unloading process from causing the equipment to idle and wait.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A silicon rod half-section cutting mechanism includes a frame, and cutting station I and cutting station II disposed on the frame. Each cutting station I and cutting station II includes a left support plate, a silicon rod support plate, and a right support plate. Both sides of the left support plate, the silicon rod support plate, and the right support plate extend outwards from both sides of the frame and are connected downwards to lead screw sliders. Linear lead screw slides are provided on both sides of the frame. The lead screw in the linear lead screw slide is threadedly connected to the lead screw slider, enabling cutting station I and cutting station II to move left and right on the frame. A cutting assembly is disposed on the frame.

[0008] In one embodiment, the cutting assembly includes a left cutting support plate and a right cutting support plate fixedly connected to both sides of the frame. The left cutting support plate has a driving guide wheel and a left driven guide wheel arranged sequentially from left to right on its left end, and a right driven guide wheel arranged on its right end. The right cutting support plate has a tensioning guide wheel and a left driven guide wheel I arranged sequentially from left to right on its left end, and a right driven guide wheel II arranged on its right end.

[0009] In one embodiment, the driving guide wheel, the left driven guide wheel, the right driven guide wheel, the tensioning guide wheel, the left driven guide wheel I, and the right driven guide wheel II are wound with annular diamond wire.

[0010] In one embodiment, one end of the annular diamond wire winds around the left driven guide wheel from the driving guide wheel, then around the left driven guide wheel I and the tensioning guide wheel, and finally around the right driven guide wheel II and the right driven guide wheel, closing with the annular diamond wire on the driving guide wheel to achieve winding.

[0011] In one embodiment, the annular diamond wire passes around the right driven guide wheel and the right driven guide wheel II to form a first cutting line; the annular diamond wire passes around the left driven guide wheel and the left driven guide wheel I to form a second cutting line.

[0012] In one embodiment, the left support plate is provided with a left fixing plate, and the left fixing plate is provided with a left transverse cylinder I and a left transverse cylinder II facing the right support plate.

[0013] In one embodiment, the right support plate is provided with a right fixing plate, and the right fixing plate is provided with a right transverse cylinder I and a right transverse cylinder II facing the left support plate.

[0014] In one embodiment, one end of the linear lead screw guide rail is provided with a motor that drives the lead screw guide rail to move.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model comprises a frame and two cutting stations, I and II, mounted on the frame. Each cutting station includes a left support plate, a silicon rod support plate, and a right support plate. Both sides of the left support plate, silicon rod support plate, and right support plate extend downwards from both sides of the frame and are connected to lead screw sliders. Linear lead screw slides are provided on both sides of the frame, with the lead screw in the linear lead screw slides threadedly connected to the lead screw sliders, allowing cutting stations I and II to move left and right on the frame. A cutting assembly is mounted on the frame. This design solves the technical problem of mismatched cycle times between the splitting and unloading processes, which leads to equipment idling and waiting. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0021] like Figure 1-2 As shown, this embodiment includes a frame 10, and cutting station I and cutting station II set on the frame 10. Both cutting station I and cutting station II include a left support plate 20, a silicon rod support plate 21, and a right support plate 22. The left support plate 20, silicon rod support plate 21, and right support plate 22 extend out of both sides of the frame 10 and are connected downward to lead screw sliders 23. Both sides of the frame 10 are provided with linear lead screw slide rails 40. The lead screw in the linear lead screw slide rail 40 is threadedly connected to the lead screw slider 23, so that cutting station I and cutting station II can move left and right on the frame 10.

[0022] In one embodiment, the left support plate 20, silicon rod support plate 21, and right support plate 22 are connected to the frame 10 by a lead screw and slider 23.

[0023] In this embodiment, one end of the linear lead screw slide rail 40 is provided with a motor that drives the linear lead screw slide rail 40 to move; thus, the linear lead screw slide rail 40 is driven by the motor to move, and the linear lead screw slide rail 40 enables the cutting station I and the cutting station II to move left and right on the frame 10.

[0024] The left support plate 20 is provided with a left fixing plate 24, and the left fixing plate 24 is provided with a left transverse cylinder I 25 and a left transverse cylinder II 26 facing the right support plate 22; the right support plate 22 is provided with a right fixing plate 27, and the right fixing plate 27 is provided with a right transverse cylinder I 28 and a right transverse cylinder II 29 facing the left support plate 20; thereby, the silicon rod is positioned left and right by the left transverse cylinder I 25 and the left transverse cylinder II 26 and the right transverse cylinder I 28 and the right transverse cylinder II 29.

[0025] In one embodiment, the linear screw guide rail 40 is a bidirectional linear screw guide rail 40, which allows cutting station I and cutting station II to be cut away from each other, or cutting station I and cutting station II to be cut close to each other.

[0026] The frame 10 is equipped with a cutting assembly, which includes a left cutting support plate 11 and a right cutting support plate 12 fixedly connected to both sides of the frame 10. The left cutting support plate 11 has a driving guide wheel 13 and a left driven guide wheel 14 arranged from left to right on its left end, and a right driven guide wheel 15 arranged on its right end. The right cutting support plate 12 has a tensioning guide wheel 16 and a left driven guide wheel I 17 arranged from left to right on its left end, and a right driven guide wheel II 18 arranged on its right end.

[0027] In this embodiment, a rotary motor for driving the active guide wheel 13 to rotate is connected to the bottom of the active guide wheel 13.

[0028] A ring-shaped diamond wire 19 is wound around the driving guide wheel 13, the left driven guide wheel 14, the right driven guide wheel 15, the tension guide wheel 16, the left driven guide wheel I 17, and the right driven guide wheel II 18. One end of the ring-shaped diamond wire 19 starts from the driving guide wheel 13, wraps around the left driven guide wheel 14, then around the left driven guide wheel I 17 and the tension guide wheel 16, and finally around the right driven guide wheel II 18 and the right driven guide wheel 15, closing with the ring-shaped diamond wire 19 on the driving guide wheel 13 to achieve winding. Thus, by rotating the motor, the driving guide wheel 13 is driven to rotate, and the driving guide wheel 13 synchronously drives the left driven guide wheel 14, the right driven guide wheel 15, the tension guide wheel 16, the left driven guide wheel I 17, and the right driven guide wheel II 18 to rotate through the ring-shaped diamond wire 19.

[0029] This causes the annular diamond wire 19 to bypass the right driven guide wheel 15 and the right driven guide wheel II 18 to form the first cutting line, cutting the silicon rod on the support slide I 20 or the support slide II 30; the annular diamond wire 19 then bypasses the left driven guide wheel 14 and the left driven guide wheel I 17 to form the second cutting line, cutting the silicon rod on the support slide I 20 or the support slide II 30.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
