Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing equipment, in particular to a gantry type diamond wire slicer. Background Art

[0002] In existing cutting equipment, especially slicers for cutting hard and brittle materials (such as silicon wafers, ceramics, glass, etc.), fixed cutting mechanisms are usually used. During the cutting process, the distance between the cutting line and the workbench of such a structured cutting machine is fixed, and cannot be flexibly adjusted according to the thickness of the object to be cut or the cutting requirements. This fixed distance design limits the application scope and cutting accuracy of the cutting machine, especially in situations where high-precision cutting is required, and it is difficult to meet the process requirements.

[0003] In addition, existing cutting machines usually adopt a single-arm or double-arm structure, and the space between the cutting arm and the workbench is limited, resulting in a limited range of movement of the cutting line during the cutting process, and it is impossible to achieve a wide range of cutting position adjustment. This structure not only affects the cutting efficiency, but also may lead to unstable cutting quality, especially when cutting thicker or complex-shaped objects, it is easy to have problems such as incomplete cutting or uneven cutting surface.

[0004] In order to solve the above problems, some improvement schemes have been proposed in the prior art, such as changing the distance between the cutting line and the object by adjusting the height of the workbench. However, this adjustment method usually requires a complex mechanical structure and a precise control system, which increases the manufacturing cost and maintenance difficulty of the equipment. In addition, the adjustment range of the workbench is limited, which makes it difficult to meet different cutting requirements.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] Figure 1 This is a schematic diagram of the structure of a gantry diamond wire slicer. Figure 1 As shown, and refer to Figures 2 to 7 The embodiment of the present invention provides a gantry type diamond wire slicer, which includes a housing, a gantry lifting mechanism 200, a cutting mechanism and a workbench 400. An upper cavity 110 is defined in the housing.

[0038] The gantry lifting mechanism 200 includes a gantry 210 and a lifting assembly. The gantry 210 is slidably disposed on the upper cavity 110. The gantry 210 has two cutting arms 211 extending downward, and the two cutting arms are clearance-matched. The lifting assembly controls the gantry 210 to move up and down.

[0039] The cutting mechanism includes a driving assembly 310, a driving wheel 320, a tensioning wheel 330, two supporting wheels 340 and a cutting wire. Each long driving wheel is rotatably mounted on a cutting arm 211. The driving wheel 320 and the tensioning wheel 330 are both rotatably arranged above the supporting wheel 340. The cutting wire is mounted on the driving wheel 320, the tensioning wheel 330 and the supporting wheel 340. The driving assembly 310 is connected to the driving wheel 320 and is used to drive the driving wheel 320 to rotate. The workbench 400 is arranged at the bottom of the upper cavity 110 and is located between the two cutting arms 211.

[0040] Specifically, the gantry 210 is arranged to be movable up and down, and can adjust the distance between the cutting wire and the workbench 400, so as to adjust the relative position of the cutting wire on the object to be cut, so as to achieve the effect of quickly adjusting the cutting position. Further, the lower end of the gantry 210 extends downward to form two cutting arms 211, so that the gantry 210 as a whole is in a "C" - shaped structure. A clearance fit between the two cutting arms 211 forms a retracting space. Since the workbench 400 is arranged between the two cutting arms 211, when the gantry 210 moves downward, the workbench 400 is located in the retracting space, so that the cutting wire can move downward to the tabletop of the workbench 400, so as to ensure the cutting quality of the object by the cutting wire and the integrity of the cutting action.

[0041] During operation, the object to be cut is placed on the workbench 400, the driving assembly 310 is started, the driving assembly 310 drives the driving wheel 320 to rotate, the driving wheel 320 drives the cutting wire and the supporting wheel 340 and the tensioning wheel 330 to rotate synchronously, and makes the cutting wire perform a cutting movement. When it is necessary to cut downward, the lifting assembly is started, and the lifting assembly drives the gantry 210 to move downward, so that the cutting wire cuts the object downward.

[0042] In some embodiments of the present invention, as Figure 4 and Figure 7 shown, the cutting mechanism further includes a tensioning assembly 230. A sliding groove 212 is provided on the gantry 210, and a slider 213 is slidably arranged in the sliding groove 212. The tensioning wheel 330 is rotatably arranged on the slider 213. The tensioning assembly 230 is arranged on the gantry 210 and is connected to the slider 213 and is used to drive the slider 213 to slide.

[0043] Specifically, the tensioning wheel 330, the driving wheel 320 and the two supporting wheels 340 are located in the same plane, and the cutting wire forms a rectangular structure. Further, the sliding groove 212 extends in the horizontal left - right direction, and the slider 213 is arranged to slide reciprocally in the left - right direction in the sliding groove 212, and can approach or move away from the driving wheel 320, so as to drive the tensioning wheel 330 to approach or move away from the driving wheel 320, thus facilitating the tensioning and replacement of the cutting wire.

[0044] In some embodiments of the present invention, as Figure 7 As shown, the tensioning assembly 230 includes an electric telescopic rod 231; the electric telescopic rod 231 is fixedly disposed on the gantry 210 and fixedly connected to the slider 213. Specifically, the electric telescopic rod 231 can drive the slider 213 to slide in the sliding groove 212, thereby increasing the sliding stability of the slider 213.

[0045] In some embodiments of the present invention, Figures 3 to 6 As shown, a sliding track 410 is provided on the base of the upper cavity 110. The workbench 400 can be slidably arranged on the sliding track 410, and a protective cover 420 is provided on the sliding track 410. Specifically, the sliding track 410 slides in the front-to-back direction so that the workbench 400 can be slidably arranged in the front-to-back direction. The front-to-back movement of the workbench 400 and the up-and-down movement of the gantry 210 cooperate with each other to increase the flexibility of cutting and can be adapted to cutting objects of complex shapes. Furthermore, the provision of the protective cover 420 can protect the track, thereby preventing debris from infiltrating the sliding track 410. In this embodiment, the sliding track 410 can adopt a double track, which can increase the stability of the sliding of the workbench 400.

[0046] In some embodiments of the present invention, Figure 5 As shown, the sliding track 410 is located above the bottom of the upper cavity 110, and the protective cover 420 is in the shape of a rectangular cover. Two fixing platforms 111 are provided on both sides of the length direction of the sliding track 410. The protective cover 420 is sleeved on the sliding track 410 and fixed to the fixing platform 111 so that the protective cover 420 and the bottom clearance of the upper cavity 110 are matched. A sliding sleeve 430 is slidably sleeved on the protective cover 420, and the sliding sleeve 430 is embedded with the protective cover 420, and the sliding sleeve 430 is slidably connected with the sliding track 410, and the fixing platform 111 is set on the sliding sleeve 430.

[0047] Specifically, there are four fixing platforms 111, which are fixed to the four corners of the bottom of the protective cover 420, respectively, so that there is a gap between the bottom of the protective cover 420 and the bottom of the upper cavity 110, so that the sliding sleeve 430 can be slidably mounted on the protective cover and provide a sliding space for the sliding sleeve 430. Further, the sliding sleeve 430 and the protective cover 420 are embedded to increase the stability of the sliding sleeve 430 sliding forward and backward. Further, the protective cover 420 is a rectangular cover-like structure, which is mounted on the sliding track 410 in an inverted manner.

[0048] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the gantry-type diamond wire slicer also includes a cutting fluid circulation mechanism, and the housing further defines a lower cavity 120 located below the upper cavity 110. The cutting fluid circulation mechanism is located in the lower cavity 120. The cutting fluid circulation mechanism includes a liquid storage tank 520, a liquid spraying pipe, and a pressure pump 530. The pressure pump 530 is connected to the liquid spraying pipe and is located in the liquid storage tank 520, and is used to introduce the cutting fluid to the cutting position of the cutting line.

[0049] Specifically, the pressure pump 530 pumps the beveling fluid from the fluid storage tank 520 upward to the position where the cutting line is cut.

[0050] In some embodiments of the present invention, Figure 3 As shown, the upper cavity 110 is provided with an upper water hole 112 and a lower water hole 113 communicating with the lower cavity 120 at the bottom. The lower water hole 113 is communicated with the liquid storage tank 520. The shower pipe is inserted into the upper water hole 112.

[0051] In some embodiments of the present invention, Figure 6 As shown, the lifting assembly includes a lifting screw 221, a lifting motor 222 and a lifting connection block 223. The lifting connection block 223 is fixedly mounted on the gantry 210, and the lifting screw 221 is rotatably inserted into the lifting connection block 223 to form a screw nut mechanism. The lifting motor 222 is fixedly arranged on the housing and connected to the lifting screw 221. Specifically, the lifting connection block 223 and the lifting screw 221 constitute a screw nut mechanism that can increase the stability of the gantry 210 during the rising or falling process.

[0052] In some embodiments of the present invention, Figure 6 As shown, a housing 100 is disposed outside the gantry 210 ; grill holes 214 are provided at the bottom of the housing 100 corresponding to the two cutting arms 211 .
