In the process of coating production and processing of silicon wafers, a graphite boat is generally adopted as a carrier device so as to realize coating processing of silicon wafers in batches. The graphite boat generally includes the graphite boat piece that a plurality of equidistant range set up, all is equipped with a plurality of bearing positions on every graphite boat piece, and the both ends of graphite boat all are equipped with the bulge so that fixed connection, and the bearing position on the graphite boat piece comprises the bearing groove of fretwork. In the prior art, for the production of the graphite boat piece, the general process comprises cutting, saw blade, grooving and finish machining; specifically, firstly, cutting materials to obtain graphite blocks with specified sizes, then, carrying out saw blade processing on the graphite blocks to form a plurality of independent graphite flakes, wherein the graphite flakes are thin and have the thickness generally ranging from 1 mm to 5mm, then, carrying out grooving and hole digging processing on the graphite flakes one by one to obtain semi-finished graphite boat pieces, and finally, carrying out finish machining on the inner frame, the outer shape and the like to obtain finished graphite boat pieces. In the production cost of the graphite boat, the proportion of graphite materials is nearly half, but in the production process of the traditional graphite boat piece, a large amount of graphite raw materials can be wasted by utilizing a metal saw blade, and particularly in the process of grooving the saw blade, the produced waste is too thin or too broken to be reused, so that the production cost is increased; simultaneously, the thickness dimension of the graphite flake that forms after the saw bit processing is on the small side, breaks at the grooving in-process easily, leads to the rejection rate high to grooving adds the time need to fix a position the graphite flake once more, and the machining precision of a plurality of graphite boat pieces is difficult to guarantee.

To this end, referring to fig. 1, the present invention provides a wire saw apparatus for cutting graphite sheets. The above-mentioned unfavorable conditions can be effectively improved.

The graphite wire saw for multi-group circulating cutting comprises a machine tool 100, in the embodiment, the adopted bedroom machine tool 100 is characterized in that the machine tool 100 comprises a workbench 110, and a pushing device 200 and a wire saw device 300 are arranged on the workbench 110. The pushing device 200 may be composed of a servo motor 210 and a screw rod driving mechanism, and the servo motor 210 drives a push plate 220 to move back and forth through the screw rod driving mechanism. The push plate 220 is connected with the worktable 110 in a front-back sliding manner. A slide rail 120 for moving graphite is disposed in front of the working table 110, and the push plate 220 is disposed on the slide rail 120. Behind the slide rail 120, the wire saw device 300 is provided.

Specifically, the wire saw apparatus 300 includes a vertical support 330, the support 330 is fixed to the machine tool 100, and in some other embodiments, the support 330 may be integrated with the machine tool 100. The upper side of the front of the bracket 330 is provided with a first reel 310, the lower side is provided with a second reel 320, in addition, the back of the bracket 330 is also provided with a driving mechanism 340, the driving mechanism 340 comprises a first driving unit and a second driving unit, the first driving unit independently drives the first reel 310 to rotate, and the second driving unit independently drives the second reel 320 to rotate. The first pulley 310 and the second pulley 320 rotate in the same direction, and in this embodiment, the structure of the first pulley 310 is the same as that of the second pulley 320. Specifically, the driving mechanism 350 may include a main motor, a first reduction gearbox and a second reduction gearbox, the main motor is simultaneously in driving connection with the two reduction gearboxes, and each reduction gearbox is the driving unit. Of course, since the first and

second pulleys

310 and 320 need to be rotated synchronously, the output rotation speeds of the first and second driving units should be the same. A plurality of diamond wires 340 are arranged between the first wire wheel 310 and the second wire wheel 320, and a plurality of diamond wires Jin Gangsi are arranged in parallel on the wheel surface, for example, a plurality of annular wheel grooves may be arranged on the wheel surfaces of the first wire wheel 310 and the second wire wheel 320 at equal intervals, and the diamond wires 340 are clamped in the wheel grooves. Meanwhile, the axes of the first pulley 310 and the second pulley 320 are not perpendicular to the moving direction of the pushing device 200. In this embodiment, the bracket 330 includes a mounting surface, and a normal direction of the mounting surface is perpendicular to a moving direction of the push plate 220. The moving direction of the push plate 220 is defined as the front-rear direction, and the normal direction of the mounting surface is defined as the left-right direction. And an included angle formed between the axis of the first reel 310 and the front-rear direction is α, and the value range of α is 70 ° to 89 °. Since the diamond wire 340 is wound between the two reels, and the two reels are arranged symmetrically up and down, the diamond wire 340 forms a front section 341 and a rear section 342 between the two reels, the front section 341 moves from the first reel 310 to the second reel 320, and the rear section 342 moves from the second reel 320 to the first reel 310. The front section 341 and the rear end 342 both move in the vertical direction, but since the axis of the first spool 340 is not perpendicular to the moving direction of the push plate 220, the front section 341 and the rear end 342 are not located on the same plane in the horizontal direction. That is, the front section 341 and the rear end 342 are offset in the left-right direction. The smaller the angle α, the greater the misalignment between the front section 341 and the rear section 342, and conversely, the closer the angle α is to 90 °, the smaller the misalignment between the front section 341 and the rear section 342.

In this embodiment, the dislocation between the front section 341 and the rear section 342 is utilized, and the front section 341 and the rear section 342 are driven by the driving force of the driving unit when moving, so that the front section 341 and the rear section 342 can both cut graphite.

For example, the thickness of the graphite sheet to be processed is 2mm, and the included angle α is adjusted to make the offset distance between the front section 341 and the rear end 342 in the left-right direction be 2mm, so that when the graphite block a is pushed to move backwards on the slide rail 120, the graphite block a is cut by the front section 341 and the rear section 342. Meanwhile, since the first wire wheel 310 and the second wire wheel 320 are provided with the plurality of diamond wires 340, the graphite block a is cut into several blocks when passing through the wire saw device 300 from front to back. In this embodiment, the diamond wire 340 has 5, so that ten cuts are left when the graphite block a passes through the wire saw device 300, and compared with the conventional wire cutting equipment, only one cut is left at a time, and the efficiency of the graphite wire saw for the multi-group circular cutting of this embodiment is greatly improved.

Therefore, the size of the included angle alpha can be designed according to the actual processing requirement and in combination with the parameters such as the outer diameter of the wire wheel.

In some other implementations, there may be only one set of reduction boxes, that is, the two pulleys have a structure of driving pulley and driven pulley. This also makes the cutting efficiency of the graphite block mentioned, but since there is no power involvement on one side, the cutting effect is less than ideal, and the cuts on the side without power are rougher.

In the embodiment, the two pulleys are arranged up and down, and in other embodiments, the two pulleys can also be arranged in the left-right direction. Similarly, when the two wire wheels are arranged in the left-right direction, the axes of the wire wheels are inclined along the up-down direction, so that the front section and the rear section of the same diamond wire on the wire wheels are staggered in the up-down direction.

In a further preferred embodiment, a positioning cover 130 is disposed at the rear side of the worktable 110, and the positioning cover 130 includes an inner cavity having a size corresponding to the outer diameter of the graphite block a. The positioning cover 130 is disposed behind the wire saw device 300. Since the graphite block a is divided into a plurality of very thin graphite sheets after passing through the wire saw device 300, the graphite sheets cannot be supported well when only the front slide rail 120 plays a role of a limit. According to the scheme, the positioning cover 130 is additionally arranged behind the wire saw device 300, and the positioning cover 130 can provide multidirectional support for graphite sheets, so that the cutting quality is improved.

When the diamond wire 340 is used, elastic deformation is easily generated, so that the length of the diamond wire 340 is increased, and when the length of the diamond wire 340 is extended, the cutting effects of the front section 341 and the rear section 342 are deteriorated. To this end, in a further preferred embodiment, the wire saw device 300 further comprises a first adjustment mechanism 350, wherein the first adjustment mechanism 350 is mounted on the support 330, and the first wire wheel 310 is mounted on the first adjustment mechanism 350. For example, the first adjusting mechanism 360 may include a screw and a nut seat, and the position of the nut seat may be adjusted by rotating the screw, and the first reel 310 may be mounted on the nut seat, so that the position of the first reel 310 may be adjusted when the nut seat moves up and down relatively. So that the positional relationship between the first spool 310 and the second spool 320 can be adjusted to re-tension the diamond wire 340.

In addition, as mentioned in the above embodiments, the wire saw device 300 can adjust the axis of the wire reel. Which can be displaced simultaneously by a second adjustment mechanism (not shown) in the axis of the first 310 and second 320 pulley. For example, the second adjusting mechanism may include a worm and gear mechanism, the axes of the first pulley 310 and the second pulley 320 may be shifted through the worm and gear mechanism, and the worm and gear mechanism has good self-locking performance, so as to prevent the pulleys from being shifted during operation.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
