Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting device for processing annular semiconductor parts. Background Art

[0002] Zirconia annular wafers are common semiconductor parts, which are mostly used for the fixation and positioning of terminals. When processing them, cutting equipment is required.

[0003] When a zirconia annular wafer is cut and processed, its blank is a tubular bar. Wire cutting is adopted. The bar is pushed to the lower part of the cutting wire, and the high-speed rotating cutting wire slowly sinks to cut the bar into multiple annular thin slices. In actual use, there are some functional deficiencies and room for improvement. For example, during the cutting process, the bar is displaced downward to the lower part of the cutting wire under the transmission of the conveyor belt. In the middle and later stages of cutting, it is difficult to fix the bar with insufficient length itself. The bar is prone to displacement during the cutting process, and the annular thin slices are prone to turn outwards and scatter after cutting, and need to be picked up one by one manually, which is rather troublesome and does not have the function of pushing materials to prevent scattering.

[0004] Now, a new cutting device for processing annular semiconductor parts is proposed to solve the above problems. Content of the Utility Model

[0010] Preferably, the horizontal center lines of the hollow disk, the vacuum suction cups, and the air pump interface coincide, and the bottom end of the hollow disk is higher than the top end of the tube and rod bracket.

[0011] Preferably, two sets of steel positioning plates are fixedly connected to the inner parts of the left and right sides of the bottom box body.

[0013] Preferably, two sets of fourth electric cylinders are installed on the other side of the sliding frame. A concave frame is installed at the top end of the fourth electric cylinder. A supporting roller is movably connected between the front and rear ends inside the concave frame.

[0014] Preferably, there is a distance between the concave frame and the sliding frame, and the top end of the supporting roller is in contact with the cutting line.

The pushing assembly includes a second electric cylinder 13, the second electric cylinder 13 is arranged on one side above the supporting groove 2, a third electric cylinder 17 is arranged on the other side above the supporting groove 2, hollow disks 14 are respectively fixedly connected to one sides of the second electric cylinder 13 and the third electric cylinder 17, multiple groups of vacuum suction cups 15 are installed on one side of the hollow disk 14, and an air pump interface 16 is fixedly connected to the top of the hollow disk 14;

[0029] The specifications of the second electric cylinder 13 and the third electric cylinder 17 are the same. The horizontal center lines of the second electric cylinder 13 and the third electric cylinder 17 coincide. The vacuum suction cups 15 are arranged at equal intervals. The vacuum suction cups 15 are elastic. The horizontal center lines of the hollow disk 14, the vacuum suction cups 15, and the air pump interface 16 coincide. The bottom end of the hollow disk 14 is higher than the top end of the tube bar bracket 4, which can fix the bar stock and ensure stable loading and unloading.

[0030] Specifically, as Figure 1 , Figure 4 and Figure 5 shown, the second electric cylinder 13 and the third electric cylinder 17 extend synchronously. The hollow bar stock is clamped in the middle by two groups of hollow disks 14. The air pump evacuates the space between the vacuum suction cups 15 and the bar stock to form suction force in the vacuum suction cups 15. During cutting, the bar stock is not easily displaced. During cutting, the second electric cylinder 13 continues to extend, and the third electric cylinder 17 continues to retract to send the bar stock below the cutting line 12.

The outermost annular thin sheet is supported by the third electric cylinder 17 and is not easily overturned and scattered, which is convenient for batch material taking.

[0031] Embodiment 2: Two groups of steel positioning plates 18 are fixedly connected to the inner parts of the left and right sides of the bottom box body 1.

The position spacings of the internal thread positioning holes 19 and the positioning screw holes 21 correspond one by one. The positioning bolts 23 penetrate through the inside of the positioning screw holes 21 and extend into the inside of the internal thread positioning holes 19, which is convenient for adjusting the height of the electric cylinder.

[0032] Specifically, as Figure 1 , Figure 2 and Figure 6 shown, loosen and remove the positioning bolts 23, move the electric cylinder support plate 20 up or down, and its positioning screw holes 21 match the steel positioning plate 18 and the internal thread positioning holes 19.

[0033] Embodiment 3: Two groups of fourth electric cylinders 24 are installed on the other side of the sliding frame 9. A concave frame 25 is installed at the top end of the fourth electric cylinder 24. A supporting roller 26 is movably connected between the front and rear ends inside the concave frame 25. There is a distance between the concave frame 25 and the sliding frame 9. The top end of the supporting roller 26 is in contact with the cutting line 12, which is convenient for adjusting the tightness of the wire saw.

[0034] Specifically, as Figure 1 ,Figure 2 and Figure 3 As shown in Figure 3 , start the fourth electric cylinder 24 to extend it upward by a certain distance. The supporting roller 26 in the concave frame 25 will lift and tighten the cutting wire 12 to keep it in a tight state. When the wire needs to be replaced later, just retract the fourth electric cylinder 24.

[0035] Working principle: When the present utility model is in use, first, horizontally place the zirconia hollow rod on the pipe and rod bracket 4. The air pump interfaces 16 at the tops of the two groups of hollow discs 14 are all connected to the air pump pipe group. The second electric cylinder 13 and the third electric cylinder 17 extend synchronously, and the hollow rod is clamped in the middle by the two groups of hollow discs 14. The air pump evacuates the space between the vacuum suction cups 15 and the rod to form suction force in the vacuum suction cups 15, so that the rod is not easily displaced during cutting. During cutting, the second electric cylinder 13 continuously extends and the third electric cylinder 17 continuously retracts to send the rod below the cutting wire 12. The drive motor 10 drives the wire wheel 11 to rotate at a high speed, and the first electric cylinder 8 pushes the sliding frame 9 to slowly press down, and the cutting wire 12 cuts the rod. The outermost annular thin sheet is supported by the third electric cylinder 17 and is not easily toppled and scattered, which is convenient for batch material taking. Replace the hollow discs 14 according to the size of the rod. At the same time, adjust the heights of the second electric cylinder 13 and the third electric cylinder 17. The heights of the electric cylinder supporting plate 20 and the electric cylinder bracket 22 can be directly adjusted. First, loosen and remove the positioning bolts 23, move the electric cylinder supporting plate 20 up or down. The positioning screw holes 21 on it match the steel positioning plate 18 and the internal thread positioning holes 19, and then drive in the positioning bolts 23 to complete the height fixation, and the height adjustment is also completed synchronously. The cutting wire 12 is driven by the wire wheel 11. As the cutting time increases, the cutting wire 12 is likely to become loose. At this time, start the fourth electric cylinder 24 to extend it upward by a certain distance. The supporting roller 26 in the concave frame 25 will lift and tighten the cutting wire 12 to keep it in a tight state. When the wire needs to be replaced later, just retract the fourth electric cylinder 24.
