Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a wire wheel tensioning device for a diamond wire slicing machine. Background Technology

[0002] In existing cutting equipment, especially slicing machines used for cutting hard and brittle materials (such as silicon wafers, ceramics, and glass), a fixed cutting mechanism is typically used. In this type of cutting machine, the distance between the cutting line and the worktable is fixed during the cutting process, and cannot be flexibly adjusted according to the thickness of the object being cut or the cutting requirements. This fixed-distance design limits the applicability and cutting accuracy of the cutting machine, especially in applications requiring high-precision cutting, making it difficult to meet process requirements.

[0003] Furthermore, existing cutting machines typically employ a single-arm or double-arm structure, with limited space between the cutting arm and the worktable. This restricts the range of movement of the cutting line during the cutting process, preventing extensive adjustments to the cutting position. This structure not only affects cutting efficiency but can also lead to inconsistent cutting quality, especially when cutting thicker or more complex objects, easily resulting in incomplete cuts or uneven cut surfaces.

[0004] To address these issues, existing technologies have proposed several improvements, such as adjusting the height of the worktable to change the distance between the cutting line and the object. However, this adjustment method typically requires complex mechanical structures and precise control systems, increasing manufacturing costs and maintenance complexity. Furthermore, the limited adjustment range of the worktable makes it difficult to meet diverse cutting needs.

[0005] Therefore, there is an urgent need for a cutting device that can flexibly adjust the distance between the cutting line and the worktable and has a large cutting range, in order to improve cutting quality and efficiency and meet the needs of different cutting processes. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Figure 1 This is a schematic structural diagram of the wire wheel tensioning device used in a diamond wire slicing machine, such as... Figure 1 As shown, and refer to Figures 2 to 8 This utility model embodiment provides a wire wheel tensioning device for a diamond wire slicing machine. The wire wheel tensioning device for a diamond wire slicing machine includes a machine housing, a gantry lifting mechanism 200, a cutting mechanism, and a worktable 400. An upper cavity 110 is defined inside the machine housing.

[0039] The gantry lifting mechanism 200 includes a gantry frame 210 and a lifting assembly. The gantry frame 210 is slidably mounted on the upper cavity 110. The gantry frame 210 has two downwardly extending cutting arms 211, which are fitted together with a clearance. The lifting assembly controls the up and down movement of the gantry frame 210.

[0040] The cutting mechanism includes a drive assembly 310, a drive wheel 320, a tension wheel 330, two support wheels 340, and a cutting wire. Each long feed wheel is rotatably mounted on a cutting arm 211. The drive wheel 320 and the tension wheel 330 are both rotatably positioned above the support wheels 340. The cutting wire is mounted on the drive wheel 320, the tension wheel 330, and the support wheels 340. The drive assembly 310 is connected to the drive wheel 320 and is used to drive the drive wheel 320 to rotate. The worktable 400 is located at the bottom of the upper cavity 110 and between the two cutting arms 211.

[0041] Specifically, the gantry 210 is vertically movable, allowing adjustment of the distance between the cutting line and the worktable 400, thereby adjusting the relative position of the cutting line on the object to be cut, achieving rapid adjustment of the cutting position. Furthermore, two cutting arms 211 extend downwards from the lower end of the gantry 210, giving the gantry 210 an overall "U"-shaped structure. The gap between the two cutting arms 211 creates a clearance space. Since the worktable 400 is positioned between the two cutting arms 211, the downward movement of the gantry 210 causes the worktable 400 to fall within this clearance space, allowing the cutting line to move downwards onto the surface of the worktable 400, ensuring the cutting quality and integrity of the cutting action.

[0042] During operation, the object to be cut is placed on the worktable 400, and the drive assembly 310 is activated. The drive assembly 310 drives the drive wheel 320 to rotate, which in turn drives the cutting wire, support wheel 340, and tension wheel 330 to rotate synchronously, causing the cutting wire to perform a cutting motion. When downward cutting is required, the lifting assembly is activated, which moves the gantry 210 downward, thereby causing the cutting wire to cut the object downward.

[0043] In some embodiments of this utility model, such as Figure 4 and Figure 7As shown, the cutting mechanism also includes a tensioning mechanism 230. A sliding groove 212 is provided on the gantry frame 210, and a tensioning slider 213 is slidably disposed within the sliding groove 212. A tensioning wheel 330 is rotatably mounted on the tensioning slider 213. The tensioning mechanism 230 is mounted on the gantry frame 210 and connected to the tensioning slider 213, used to drive the tensioning slider 213 to slide.

[0044] Specifically, the tensioning wheel 330, the drive wheel 320, and the two support wheels 340 are located on the same plane, forming a rectangular structure for the cutting line. Furthermore, the sliding groove 212 extends horizontally, and the tensioning slider 213 is reciprocating horizontally within the sliding groove 212, moving closer to or further away from the drive wheel 320. This, in turn, causes the tensioning wheel 330 to move closer to or further away from the drive wheel 320, facilitating the tensioning and replacement of the cutting line.

[0045] In some embodiments of this utility model, such as Figure 7 As shown, the tensioning mechanism 230 includes an electric telescopic rod 231; the electric telescopic rod 231 is fixedly mounted on the gantry frame 210 and is fixedly connected to the tensioning slider 213. Specifically, the electric telescopic rod 231 can be driven to slide within the sliding groove 212, thereby increasing the sliding stability of the tensioning slider 213.

[0046] In a further embodiment, such as Figure 8 As shown, the tensioning mechanism 230 also includes a tensioning slide rail 232, and a tensioning frame 240 is provided on the gantry 210. A tensioning slider 213 is disposed on the tensioning frame 240 and extends in the left-right direction. The tensioning slider 213 is slidably mounted on the tensioning slide rail 232. The tensioning frame 240 includes multiple fixed posts 242 and fixed plates 241. The multiple fixed posts 242 are evenly distributed around the circumference of the sliding groove 212. The fixed posts 242 extend in the front-back direction, with their front ends fixedly connected to the gantry 210. The tensioning slide rail 232 is fixedly disposed on the fixed plate 241, and the fixed plate 241 is fixedly connected to the rear ends of the fixed posts 242.

[0047] In some embodiments of this utility model, such as Figures 3 to 6 As shown, a sliding rail 410 is provided on the base of the upper cavity 110. The worktable 400 is slidably mounted on the sliding rail 410, and a protective cover 420 is provided on the sliding rail 410. Specifically, the sliding rail 410 slides in the front-to-back direction, allowing the worktable 400 to be slidably mounted in the same direction. The coordination between the front-to-back movement of the worktable 400 and the up-and-down movement of the gantry 210 increases the flexibility of cutting and allows for the cutting of objects with complex shapes. Furthermore, the protective cover 420 protects the rail, preventing debris from entering the sliding rail 410. In this embodiment, the sliding rail 410 can be a double rail, which increases the stability of the sliding of the worktable 400.

[0048] In some embodiments of this utility model, such as Figure 5 As shown, the sliding track 410 is located above the bottom of the upper cavity 110, and the protective cover 420 is rectangular. Two fixed platforms 111 are provided on both the left and right sides along the length of the sliding track 410. The protective cover 420 is fitted onto the sliding track 410 and fixed to the fixed platforms 111, allowing a clearance fit between the protective cover 420 and the bottom of the upper cavity 110. A sliding sleeve 430 is slidably fitted onto the protective cover 420, with the sliding sleeve 430 embedded in the protective cover 420 and slidably connected to the sliding track 410. The fixed platforms 111 are located on the sliding sleeve 430.

[0049] Specifically, four fixing platforms 111 are fixed to the four corners of the bottom of the protective cover 420, creating a gap between the bottom of the protective cover 420 and the bottom of the upper cavity 110. This allows the sliding sleeve 430 to slide onto the protective cover and provides sliding space for the sliding sleeve 430. Furthermore, the sliding sleeve 430 and the protective cover 420 are embedded together to increase the stability of the sliding sleeve 430 during forward and backward sliding. Furthermore, the protective cover 420 has a rectangular cover structure and is installed upside down on the sliding rail 410.

[0050] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the wire sheave tensioning device for the diamond wire slicer also includes a cutting fluid circulation mechanism, and a lower cavity 120 is defined within the housing, located below the upper cavity 110. The cutting fluid circulation mechanism is located within the lower cavity 120. The cutting fluid circulation mechanism includes a reservoir 520, a spray pipe, and a pressure pump 530. The pressure pump 530 is connected to the spray pipe and is located within the reservoir 520, used to guide the cutting fluid to the cutting position of the cutting wire.

[0051] Specifically, the pressure pump 530 pumps the cutting fluid upward from the storage tank 520 to the position where the cutting line is cut.

[0052] In some embodiments of this utility model, such as Figure 3 As shown, the bottom of the upper cavity 110 is provided with an upper water hole 112 and a lower water hole 113 that connect to the lower cavity 120. The lower water hole 113 is connected to the liquid storage tank 520. The spray pipe is inserted into the upper water hole 112.

[0053] In some embodiments of this utility model, such as Figure 6As shown, the lifting assembly includes a lifting screw 221, a lifting motor 222, and a lifting connecting block 223. The lifting connecting block 223 is fixedly installed on the gantry frame 210, and the lifting screw 221 is rotatably inserted into the lifting connecting block 223 to form a screw-nut mechanism. The lifting motor 222 is fixedly mounted on the housing and connected to the lifting screw 221. Specifically, the screw-nut mechanism formed by the lifting connecting block 223 and the lifting screw 221 increases the stability of the gantry frame 210 during its ascent or descent.

[0054] In some embodiments of this utility model, such as Figure 6 As shown, a housing 100 is provided on the outside of the gantry frame 210; the bottom of the housing 100 corresponding to the two cutting arms 211 is provided with grid holes 214.

[0055] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
