Description

Technical Field

[0001] This utility model relates to the field of semiconductor equipment, and in particular to a cooling water regulating device for a cutting machine that is adapted to the size of the blade. Background Technology

[0002] In the semiconductor industry, thousands or even tens of thousands of chips are typically connected together on a single wafer. A certain gap exists between the chips; this gap is called a dicing track or dicing run. The process of separating each chip, which has independent electrical properties, is called dicing or cutting. Abrasive wheel cutting is a mainstream technology in the cutting process. It boasts low machine and consumable costs, mature technology, and high cost-effectiveness, thus enjoying a relatively high market share.

[0003] In abrasive wheel cutting, the abrasive wheel cutter rotates at 30,000 to 60,000 revolutions per minute to cut the kerf of the wafer. Simultaneously, the worktable carrying the wafer moves in a straight line at a certain speed along the tangent direction of the contact point between the blade and the wafer. This back-and-forth motion separates the chips on the wafer one by one. During the cutting process, the main purpose of the cutting water is to cool and clean the high-speed abrasive wheel cutter, while also washing away the debris generated during wafer cutting to prevent debris from remaining on the blade and contaminating the wafer. Therefore, the location of the cutting cooling water (the location of the water spray pipe) is particularly important.

[0004] Switching between different sized grinding wheels requires adjusting the water spray position. Improper adjustment can lead to minor issues like reduced cutting quality and shorter grinding wheel life, affecting cutting yield; more serious problems include water spray damaging the wafer, causing wafer scrap, or colliding with critical components like flanges or spindles, resulting in spare parts damage and equipment downtime. In actual production, the cooling water position (water spray position) needs manual adjustment. Because the distance between the water spray and the blades is short, the adjustment space is limited, making operation difficult and resulting in low precision.

[0005] Therefore, providing a cooling water regulating device for a cutting machine that adapts to the blade size is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0032] Referring to Figures 1-3 , Figures 1-3 The utility model discloses a cutting machine cooling water adjusting device of adapting blade size provides a kind of main view, side view sectional view and plan view in one of exemplary embodiment of the utility model, including adjusting main seat 1, adjusting vice seat 2 and adjusting bolt 3;

[0033] The adjusting main seat 1 is fixedly installed on one side of the cutting machine blade 4, the adjusting bolt 3 is vertically arranged and includes head adjusting end 301, middle threaded end 302 and tail fixed end 303, the tail fixed end 303 of adjusting bolt 3 is rotatably connected with adjusting vice seat 2, and the middle threaded end 302 of adjusting bolt 3 is threadedly connected with adjusting main seat 1;The cooling water pipe 5 is fixed on the adjusting vice seat 2, and the water outlet end 501 of the cooling water pipe 5 is arranged on the side surface of the cutting machine blade 4.

[0034] Specifically, the water outlet end 501 of the cooling water pipe 5 is used to cool and clean the cutting machine blade 4 in high-speed operation (or subsequent shutdown), and to flush away the debris generated by cutting the wafer on the cutting machine blade 4. However, as shown in the figure, the cutting machine blade 4 has different sizes, such as 2-inch grinding wheel cutter, 3-inch grinding wheel cutter, 5-inch grinding wheel cutter, so for cutting machine blades 4 of different sizes, if the water outlet end 501 of the cooling water pipe 5 is in the same position, the cooling and cleaning effect will be affected. At the same time, due to the close distance between the water outlet end 501 of the cooling water pipe 5 and the cutting machine blade 4, the debugging space is narrow, not easy to operate and the adjustment accuracy is low. Figure 1

[0035] In the present exemplary embodiment, the position of the cooling water pipe 5 is adjusted to be away from the cutting machine blade 4, that is, by adjusting the main seat 1, the adjusting screw 3 and the adjusting screw 3, in use: first, install the cutting machine blade 4 of the corresponding size, then rotate the adjusting screw 3 on the adjusting main seat 1, so as to further make the adjusting auxiliary seat 2 installed with the cooling water pipe 5 move up and down in the vertical direction, and then drive the water outlet end 501 of the cooling water pipe 5 to move up and down, so as to adjust the water spraying position.

[0036] Therefore, in the present exemplary embodiment, by adjusting the main seat 1, the adjusting auxiliary seat 2 and the adjusting screw 3, the position of the water outlet end 501 of the cooling water pipe 5 is adjusted to be away from the cutting machine blade 4, so that the whole adjustment process is safe and easy to operate, and the screw adjustment distance is controllable, which improves the adjustment accuracy.

At this time, rotating the adjusting bolt 3, the inner ring rotates with it, and the outer ring is fixed with the adjusting secondary seat 2, so the adjusting secondary seat 2 will perform a lifting action with the rotation of the adjusting bolt 3. In addition, in order to prevent the adjusting secondary seat 2 from rotating during lifting (to keep the outlet end 501 of the cooling water pipe 5 horizontally fixed), one side of the adjusting secondary seat 2 can be abutted against the adjusting primary seat 1.

[0038] More preferably, in an example embodiment, as shown in Figure 3 the head adjusting end 301 of the adjusting bolt 3 is provided with a one-way groove 30101, and the outer periphery of the adjusting threaded hole of the adjusting primary seat 1 matched with the adjusting bolt 3 is provided with an indication scale line 101 matched with the size of the blade.

[0046] Specifically, since the adjusting auxiliary seat 2 is installed with the cooling water pipe 5 and has a certain weight, only connecting and supporting through the adjusting bolt 3 will reduce the service life of the adjusting bolt 3, and the process misoperation will also cause height misadjustment. Therefore, in the present exemplary embodiment, the first fixing installation holes 10201 of the vertical fixing part 102 of the adjusting main seat 1 are provided with second fixing installation holes 201 matching the first fixing installation holes 10201 in the horizontal direction of the adjusting auxiliary seat 2, and after the position switching of the adjusting auxiliary seat 2 is completed, the adjusting auxiliary seat 2 is fixed on the adjusting main seat 1 by using the supporting bolt 202 passing through the first fixing installation holes 10201 and the second fixing installation holes 201, so as to reduce the stress of the adjusting bolt 3 and avoid the subsequent misoperation causing the rotation of the adjusting bolt 3.
