Description

Technical Field

[0002] Flying crystals are an unavoidable defect in the semiconductor, optoelectronics and other industries during the cutting and dicing process.

[0003] Currently, in existing semiconductor dicing blade devices, there is a hub step between the hub and the dicing blade. During dicing, the dicing debris flies up and bounces off the hub step, hitting the product or the dicing blade, causing damage to the product or the dicing blade. This results in scrapped products or damaged dicing blades, reduced product yield, and frequent replacement of the dicing blade.

[0004] For example, in the anti-flying crystal slicing blade device disclosed in CN213829776U, a slicing blade assembly is inserted into the bottom of the slicing blade hub. Symmetrical pins are slidably provided at both ends of the slide groove. The ends of the two pins that are far apart from each other protrude through the side wall of the slide groove on the same side and protrude from the outside of the slicing blade hub. This device allows the slicing blade assembly to be replaced. However, the device requires the operator to use both hands to control the pins to fix the blade head assembly. The operation method is cumbersome and the installation method is complicated, resulting in poor practicality.

[0005] Therefore, it is necessary to provide a device to prevent flying crystal dicing blades to solve the above-mentioned technical problems. Utility Model Content

Figure 4 for Figure 3 The enlarged schematic diagram at point A is shown. A device for preventing crystal flying during slicing includes: a connector 1 and a slicing blade hub 2;

[0030] The mounting groove 5 is located in the middle of the bottom of the slicing blade hub 2, and the mounting groove 5 has a slot 6 located in the middle of the top of the inner wall of the mounting groove 5.

[0031] The slicing blade assembly 3 is disposed inside the mounting groove 5, and the slicing blade assembly 3 includes a blade head 31, an assembly post 32, and a retaining groove 33;

[0032] Two sliding holes 8 are respectively opened on both sides of the outer surface of the scriber hub 2. The inner wall of the slot 6 is provided with sliding grooves 7 on both sides. One side of the bottom of the inner wall of the sliding groove 7 is connected to a limiting groove 9. A sliding rod 10 is fixedly installed inside the limiting groove 9. A spring 11 is sleeved on one side of the outer surface of the sliding rod 10.

[0033] The limiting device 4 is slidably installed inside the slide groove 7. The limiting device 4 includes a moving rod 41, a moving block 42, a pressing block 43, a pushing block 44, and a pressing plate 45.

[0034] The cutter head 31 is disposed inside the mounting groove 5, the assembly column 32 is fixedly installed in the middle of the top of the cutter head 31, and the two slots 33 are respectively opened on both sides of the outer surface of the assembly column 32.

[0035] The movable rod 41 is slidably installed inside the sliding hole 8, the movable block 42 is fixedly installed at one end of the movable rod 41, the pressing block 43 is fixedly installed on one side of the surface of the movable block 42, the pressing plate 45 is fixedly installed at the other end of the movable rod 41, and the push block 44 is fixedly installed on one side of the outer surface of the movable block 42.

[0036] The push block 44 is sleeved on the other side of the outer surface of the slide rod 10, and one end of the spring 11 is fixedly connected to the surface of the push block 44.

[0037] The cutting head 31 is adapted to the mounting groove 5, and the assembly column 32 is adapted to the slot 6.

[0038] The extrusion block 43 is triangular in shape, with an inclined bottom and a right-angled top, which facilitates the upward movement of the assembly column 32 and pushes the extrusion block 43 into the interior of the slide groove 7 along the extrusion surface.

[0039] The working principle of the anti-flying crystal slicing blade device provided by this utility model is as follows:

[0040] During operation, the user first holds the blade 31 and inserts it into the mounting slot 5. The assembly column 32 is embedded into the slot 6. The assembly column 32 moves from bottom to top, pushing the inclined surface at the bottom of the extrusion block 43. The extrusion block 43 is pushed into the slide groove 7. The extrusion block 43 drives the moving block 42 and the moving rod 41 to slide inside the slide groove 7. The moving block 42 drives the push block 44 to move. The push block 44 slides on the surface of the slide rod 10 and compresses the spring 11.

[0041] When the assembly column 32 is fully pressed into the interior of the slot 6, the slot 33 and the slide 7 are connected, the pressing block 43 is unrestricted, the restoring force of the spring 11 pushes the push block 44, the push block 44 drives the moving block 42 and the pressing block 43 to move, the pressing block 43 is embedded into the interior of the slot 33, and restricts the slicing blade assembly 3.

[0043] Compared with related technologies, the anti-flying crystal slicing blade device provided by this utility model has the following beneficial effects:

[0044] This utility model provides an anti-flying crystal slicing blade device. The blade head 31 and the assembly column 32 are installed through the mounting groove 5 and the slot 6. The assembly column 32 is embedded in the slot 6 and presses the inclined surfaces of the pressing blocks 43 on both sides, so that the pressing blocks 43 are pressed into the sliding groove 7 by the assembly column 32. The pressing blocks 43 drive the moving block 42 and the pushing block 44 to move. The pushing block 44 presses the spring 11. When the slot 33 and the sliding groove 7 are connected, the restoring force of the spring 11 pushes the pushing block 44, so that the pressing block 43 is embedded in the slot 33, thus restricting the slicing blade assembly 3 inside the mounting groove 5. When disassembling the slicing blade assembly 3, the user can pull the moving rods 41 on both sides to disengage the pressing block 43 from the slot 33. This device has a simple structure, is highly practical, and is convenient for operators to install blades with one hand.
