Description

Technical Field

[0002] In the technical field of wire cutting, taking a photovoltaic silicon rod as an example, making a silicon rod to be cut into silicon wafers generally requires processes such as truncating, squaring, grinding and polishing, slicing, etc. The slicing operation is completed by a slicing machine. The silicon rod is bonded to a crystal carrier, and the crystal carrier is clamped by a clamping device, and then the silicon rod is driven to move relative to the wire mesh through a feeding mechanism to achieve slicing. During the process of cutting the workpiece to be cut, the dropped silicon wafers, debris or scraps are likely to enter the wire mesh, causing wire jump or wire breakage, resulting in poor cutting and reducing the cutting efficiency. Therefore, a wire cutting machine is provided with a debris box for receiving cutting fluid, cutting debris, etc., and the waste liquid entering the debris box is discharged from the bottom of the debris box.

[0068] As Figure 1 shown, and with reference to Figures 2 to 13 , an embodiment of the present utility model provides a debris box assembly. The debris box assembly includes a debris box 10, and support members are connected to the outer sides of both ends of the debris box 10. Each support member has two support surfaces 21, and the two support surfaces 21 are two relatively arranged surfaces of the support member. The two support surfaces 21 respectively face both sides of the debris box 10 in the width direction of the debris box 10. The maximum distance in the horizontal direction between the two support surfaces 21 is a first distance, and the distance between the lower ends of the two support surfaces 21 is a second distance, and the first distance is greater than the second distance.

[0069] In the embodiment of the debris box assembly of the present utility model, since the debris box 10 is connected with support members, and the support members have two support surfaces 21, the support members can be configured to have a structure that is larger at the top and smaller at the bottom. The two support surfaces 21 respectively face both sides of the debris box 10 in the width direction of the debris box 10, so that the two support surfaces 21 can be directly placed on the bearing box at the end of the cutting roller. The bearing box directly supports the debris box 10 through the support surfaces 21, and the debris box 10 will not move downward. Therefore, the installation of the debris box assembly is convenient, which is beneficial to reducing production costs. The support members are directly placed, so there is no need to set up a special fastening connection device, making the structure of the debris box assembly simple and also beneficial to reducing costs. The dropped slices, debris, or scraps are received by the debris box, preventing the slices, debris, or scraps from entering the wire mesh and causing jumper or disconnection, which is beneficial to improving the cutting efficiency and reducing production costs.

[0070] In some embodiments of the present utility model, such as Figure 1 , Figure 3 and Figure 5 shown, each support member is a support plate. The thickness of the support plate is relatively small, and when the space in the cutting chamber is limited, the debris box 10 can be made relatively long, which is beneficial to receiving cutting debris; moreover, the thinner support plate can be completely placed on the bearing box, which is beneficial to improving the stability of the bearing box support, and thus beneficial to improving the smoothness of the installation of the debris box 10.

[0071] In some embodiments of the present utility model, the distance between the two support surfaces 21 of each support member becomes smaller from top to bottom. That is to say, the distance between the upper ends of the two support surfaces 21 is the largest, and the distance between the lower ends is the smallest. In some alternative embodiments of the present utility model, the distance between the two support surfaces 21 of each support member first becomes larger and then smaller from top to bottom. In this embodiment, the increasingly smaller part of the support surface 21 is used to contact and be supported by the bearing box.

[0072] In some embodiments of the present utility model, such as Figure 1 , Figure 3 and Figure 5 shown, at least part of the region of each support surface 21 is an arc surface provided in a concave shape, and the axis of the arc surface extends along the length direction of the debris box. The distance between the upper ends of the two arc surfaces of each support member is equal to or less than the first distance. The distance between the lower ends of the two arc surfaces of each support member is equal to or greater than the second distance. The distance between the upper ends of the two arc surfaces of each support member is greater than the distance between the lower ends of the two arc surfaces.

[0073] In the embodiment of the debris box assembly of the present utility model, the support surface 21 has an arc surface region, and the arc surface region can be perfectly matched with the surface of the bearing box, so that the contact support area is relatively large, which is beneficial to improving the stability of the bearing box support, and thus beneficial to improving the smoothness of the installation of the debris box 10. The side surface of the support plate is set as an arc surface adapted to the outer peripheral surface of the bearing box and can be clamped between the corresponding bearing boxes, thereby fixing the debris box 10.

[0074] In some embodiments of the present utility model, such as Figure 1 , Figure 3 and Figure 5 shown, the two support members are respectively a first support member 22 and a second support member 23. The first distance of the first support member 22 is greater than the first distance of the second support member 23, and the second distance of the first support member 22 is greater than the second distance of the second support member 23. That is to say, the two support members of the debris box assembly are of different sizes, and the width of one support plate is greater than the width of the other support plate.

[0075] Such as Figure 4 andFigure 6 , Figure 12 and Figure 13 As shown in Figure 6 , Figure 12 and Figure 13 , in a wire cutting machine, the bearing boxes are divided into two groups and arranged at both ends of the cutting roller. The bearing box at the rear end of the cutting roller is usually the rear bearing box 51, and the other group of bearing boxes is the front bearing box 52. When the rear bearing box 51 is installed on the cutting chamber frame 53, it is fixed by a flange. The front bearing box 52 needs to be disassembled when replacing the cutting roller or adjusting the axial distance of the cutting roller, so no flange is provided. That is, the distance between the two front bearing boxes 52 (the distance between the outer peripheral surfaces of the bearing boxes) is greater than the distance between the two rear bearing boxes 51. Therefore, the first support member 22 is arranged between the two front bearing boxes 52, and the second support member 23 is arranged between the two rear bearing boxes 51. Of course, in some embodiments, the width of the support member can be adjusted according to the actual application scenario.

[0076] In some embodiments of the present utility model, as Figures 1 to 6 shown, each end of the debris box 10 is provided with a first connecting plate 11, and a second connecting plate 12 is arranged on each support member. A first mounting hole 14 is arranged on one of the second connecting plate 12 and the first connecting plate 11. The first connecting plate 11 and the second connecting plate 12 are fixedly connected by a first connecting device 13. The first connecting device 13 passes through the first mounting hole 14.

[0077] In some embodiments of the present utility model, each support member is connected to the debris box 10 in a position-adjustable manner in the width direction of the debris box 10. For example, the first mounting hole 14 extends in the width direction of the debris box 10. By passing the first connecting device 13 through different positions of the first mounting hole 14, the first connecting plate 11 is adjusted in position relative to the second connecting plate 12 in the width direction of the debris box 10.

[0078] In some embodiments of the present utility model, the support plate is arranged vertically, the first connecting plate 11 is arranged horizontally, the second connecting plate 12 is arranged horizontally, and the first connecting plate 11 is arranged below or above the second connecting plate 12. The first connecting device 13 includes a bolt passing through the first mounting hole 14. Further, a nut is connected after the bolt passes through the first connecting plate 11 and the second connecting plate 12, and the nut is used for locking to realize the fastening connection between the first connecting plate 11 and the second connecting plate 12. In some other embodiments of the present utility model, the first connecting device 13 includes a screw passing through the first mounting hole 14. The screw can be fixedly arranged on the first connecting plate 11 or the second connecting plate 12, and a threaded hole is arranged on the corresponding first connecting plate 11 or the second connecting plate 12 to install the screw. And the first mounting hole 14 can be correspondingly arranged on the second connecting plate 12 or the first connecting plate 11. A nut is connected after the screw passes through the first mounting hole 14 to realize the fastening connection between the first connecting plate 11 and the second connecting plate 12.

[0079] In some embodiments of the present utility model, such as Figures 7 to 13 shown, the debris box assembly further includes two diversion boxes 30. The two diversion boxes 30 are respectively arranged at both ends of the debris box 10, and the internal space of the diversion box 30 is communicated with the debris box 10. Cutting fluid and the like in the debris box 10 will enter the diversion box 30 and be discharged from the debris box 10 through the diversion box 30. Generally, when the wire cutting machine has three cutting rollers 40, the diversion box 30 needs to be provided. The heights of two of the cutting rollers 40 are basically the same, and the other cutting roller 40 is arranged below the two cutting rollers 40 with basically the same height. The space between the three cutting rollers 40 is usually used to place the debris box 10, and the diversion box 30 is used to drain the cutting fluid and the like in the debris box 10 to one side or both sides of the lower cutting roller 40 to prevent the cutting fluid from dripping onto the lower cutting roller 40. The setting of the diversion box 30 is beneficial to the rational arrangement of the internal components in the cutting chamber of the wire cutting device.

[0080] In some embodiments of the present utility model, the diversion box 30 is connected to the debris box 10. The debris box 10 is usually fixedly installed on the frame of the wire cutting machine, and the frame usually includes a cutting chamber frame 53 or a bearing box installed on the cutting chamber frame 53. The debris box 10 is connected to the diversion box 30, and the diversion box 30 is connected to the cutting chamber frame 53. The fastening of the installation of the debris box 10 is improved through the fixed connection of the diversion box 30.

[0081] In some embodiments of the present utility model, the diversion box 30 is detachably connected to the debris box 10, which is beneficial to the installation, disassembly and assembly of the debris box 10.

[0082] In some embodiments of the present utility model, such as Figures 8 to 11 shown, each diversion box 30 is provided with at least two groups of first installation structures. Each group of first installation structures includes two first installation structures 31, which are respectively arranged on both sides of the debris box 10. A second connection device 32 is arranged on each first installation structure 31. The second connection device 32 contacts and abuts against the side surface of the debris box 10. For example, the first installation structure 31 can be a mounting plate, and a first threaded hole is arranged on the mounting plate. Or, the first installation structure 31 is a nut, which has a first threaded hole. The second connection device 32 includes a screw or a bolt. The second connection device 32 passes through the first threaded hole and contacts and abuts against the side surface of the debris box 10.

[0083] In some other embodiments of the present utility model, a matching structure is arranged on the side surface of the debris box 10, and the second connection device 32 is installed in the matching structure. For example, the first installation structure 31 has a first threaded hole, and the second connection device 32 includes a screw or a bolt. The matching structure is a second threaded hole or a first groove, and the second connection device 32 passes through the first threaded hole and enters the second threaded hole or the first groove.

[0084] In some embodiments of the present utility model, such as Figures 8 to 11 As shown, a second mounting structure 33 is provided on each diversion box 30, and a third connecting device 35 is provided on the second mounting structure 33. The third connecting device 35 is configured to connect the second mounting structure 33 and the machine frame. For example, the second mounting structure 33 includes a second mounting hole 34, and the third connecting device 35 uses the second mounting hole 34 to connect the second mounting structure 33 and the machine frame. The second mounting structure 33 is a mounting post, and the mounting post is provided with the second mounting hole 34. A third threaded hole, a second groove or a through hole is provided on the machine frame. The third connecting device 35 is a screw installed in the second mounting hole 34, and the screw is inserted into or passes through the third threaded hole, the second groove or the through hole.

[0085] In some embodiments of the present utility model, each diversion box 30 is mounted on the machine frame in an adjustable position in the up and down direction. By moving the diversion box 30 up and down, after the diversion box 30 is fixedly connected to the debris box 10 and the support surface 21 of the support member contacts the bearing box, the installation position of the diversion box 30 is determined, so that the diversion box 30 is installed in a suitable position, which is beneficial to improving the fastening of the installation of the debris box 10.

[0086] In some embodiments of the present utility model, such as Figures 8 to 11 As shown, the second mounting hole 34 is a long hole extending in the up and down direction. By changing the position of the third connecting device 35 in the height direction passing through the long hole, the installation height of the diversion box 30 is adjusted. In this embodiment, the installation position of the third connecting device 35 on the cutting chamber frame 53 remains unchanged, and the height of the diversion box 30 is adjustable by changing the installation position on the diversion box 30. Since the diversion box 30 is relatively small and easy to process, such a setting can significantly reduce costs and does not require adjustment of the structure of the cutting chamber. Of course, in some alternative embodiments of the present utility model, the installation position height of the third connecting device 35 on the cutting chamber frame 53 is adjustable, and the installation position on the diversion box 30 remains unchanged to achieve the adjustable height of the diversion box 30.

[0087] In the embodiments of the present utility model, the debris box 10 is firmly installed and fixed in the cutting chamber assembly through the diversion box 30, the support member, the bearing box, etc., so that the debris box 10 does not move, does not coat with the cutting roller, and does not interfere with the diamond wire, ensuring the smooth cutting of the ingot by the diamond wire.

[0088] In some embodiments of the present utility model, a communication hole 16 communicating with the diversion box 30 is provided at the lower part of the end face of the debris box 10. An insertion port 36 is provided on the diversion box 30. The lower parts of both ends of the debris box 10 are respectively inserted into two diversion boxes 30 through the insertion ports 36. And an insertion plate 17 is provided at the lower part of each end of the debris box 10, and the insertion plate 17 is located inside the diversion box 30. Part of the edge of the insertion port 36 contacts and abuts against the end face of the debris box 10, which can prevent the debris box 10 from moving along its length direction, that is, prevent the debris box 10 from moving in the front-back direction.

[0089] The embodiment of the present utility model also provides a wire cutting machine, which includes a cutting device and the debris box assembly in any of the above embodiments. The wire cutting machine is a cutting device for cutting hard and brittle material rods such as single-crystal silicon material rods, polycrystalline silicon material rods, sapphire rods, and magnetic material rods. The wire cutting machine has the advantages of high efficiency, high productivity, and high precision. Its principle is to rub the workpiece to be processed by a high-speed moving cutting wire to achieve the purpose of cutting. The wire cutting machine often uses single-wire, multi-wire diamond wires, etc. to cut silicon materials, etc. for truncation, squaring, and slicing in order to obtain corresponding silicon wafers or silicon materials. In this embodiment, the debris box assembly is used to receive the cutting fluid and generated cutting debris during wire cutting to prevent the cutting fluid and cutting debris from flying around. And by using the two support surfaces 21 of the debris box assembly to directly place on the bearing boxes at the ends of the cutting rollers 40, and using the bearing boxes to directly support the debris box 10 through the support surfaces 21, the debris box 10 will not move downward. Therefore, the installation of the debris box assembly is convenient, which is beneficial to reducing production costs.

[0090] Specifically, the wire cutting machine further includes a frame and two parallel cutting rollers 40. The frame includes a cutting chamber frame 53. Both ends of each cutting roller 40 are connected to the cutting chamber frame 53 through a bearing box assembly. The bearing box assembly includes a bearing box installed on the cutting chamber frame 53 and a bearing provided in the bearing box.
