Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dicing machines, and particularly relates to an adjustable water spraying cover device suitable for a dicing machine and the dicing machine. BACKGROUND

[0002] In the field of precision manufacturing of semiconductor devices, electronic components and the like, as a key processing equipment, the dicing machine undertakes the important task of accurately cutting brittle materials such as wafers and ceramic substrates into units of required size. With the continuous improvement of the requirements of the industry on product precision, processing efficiency and material utilization rate, the technical problems faced by the dicing machine in the high-speed cutting process are increasingly prominent, and the temperature control of the cutting area and the stability of the cutting process are the core factors restricting the processing quality.

[0003] At present, the dicing machine generally adopts the water spraying cooling mode to cool the cutting assembly and the workpiece body. The structure of the existing water spraying device is mostly fixed, and the water spraying angle and water flow state cannot be flexibly adjusted according to the actual cutting demand. In terms of temperature control, fixed-angle water spraying often cannot accurately guide the cooling water to the cutting center area of the cutting assembly and the workpiece body, resulting in low cooling efficiency. During the cutting process, the high-speed rotating cutting assembly and the workpiece material rub violently, which generates a large amount of heat. If the heat cannot be dissipated in time, the temperature of the cutting area will rise sharply, which not only easily causes the workpiece material to deform, concentrate internal stress and even change performance due to high temperature, but also accelerates the wear and passivation of the cutting assembly, greatly shortens its service life, increases the production cost, and also affects the stability of the processing precision.

[0004] At the same time, the water flow sprayed by the existing water spraying device will be splashed by the cutting assembly after contacting the high-speed rotating cutting assembly. These splashed water flows often directly act on the related parts of the equipment with a large impact force. Due to the lack of effective buffering and shunting structure, the violent impact of the water flow is easy to produce vibration, and these vibrations will be transmitted to the cutting assembly, causing the cutting assembly to appear a slight deviation or jitter during high-speed rotation.

In the present arrangement, it is ensured that when the connecting plate 22 moves vertically upward, the L-shaped connecting plate 221 will be moved vertically upward, and when the L-shaped connecting plate 221 moves vertically upward, the first cam 23 and the second cam 231 will be driven to rotate through the moving sliding groove 222 and the moving sliding block 223 provided at the bottom of the L-shaped connecting plate 221 and the universal joint 224 provided on the moving sliding block 223.

[0026] As shown in Figures 1 to 5 and Figures 7 to 10 As shown, further, the first turnover plate 24 and the second turnover plate 244 are symmetrical to each other, the first turnover plate 24 and the second turnover plate 244 are fixedly provided with rotating rods 241, the two rotating rods 241 are movably penetrated through the water spray cover body 15, the two rotating rods 241 are provided with bearings 242 at both ends, and each bearing 242 is arranged on the side wall of the water spray cover body 15.

[0027] Embodiment 3: As shown in Figures 1 to 10 The present application also discloses a wafer scribing machine, which comprises an adjustable water spray cover device suitable for the wafer scribing machine.

[0028] The implementation principle of the adjustable water spray cover device suitable for the wafer scribing machine and the wafer scribing machine of the present application is as follows: Firstly, the staff installs the water spraying cover body 15 on the mounting plate 141, so that the cutting assembly 16 can be ensured to be located in the inner cavity of the water spraying cover body 15. When the water spraying cover body 15 is installed, the staff connects the water supply pipe to the water spraying connector 151 (the specific installation of the water spraying cover body 15 and the water spraying connector 151 are prior art, and will not be described here) ; When the above preparation work is completed, the staff can place the workpiece on the placement table 132. When the placement is completed, the staff can adjust the position of the sliding block 124 through the vertical guide rail assembly 121, the longitudinal guide rail assembly 122 and the transverse guide rail assembly 123, so as to adjust the position of the cutting assembly 16 (the specific adjustment mode of the vertical guide rail assembly 121, the longitudinal guide rail assembly 122 and the transverse guide rail assembly is prior art) ; When the workpiece and the cutting assembly 16 are adjusted, the staff can inject water into the water supply pipe, so that the water supply pipe can spray water onto the cutting assembly 16 and the workpiece. At this time, the staff observes the position of the sprayed water between the cutting assembly 16 and the workpiece, so as to observe whether the cutting point between the cutting assembly 16 and the workpiece is reached; When the sprayed water is not at the cutting point, the staff rotates the rotating knob 2, so that the rotating knob 2 drives the threaded rod 211 to rotate. When the threaded rod 211 rotates, the connecting plate 22 can move vertically under the assistance of the guide sliding groove 213 and the guide sliding block 214 (in this technology, it is necessary to adjust the connecting plate 22 to move vertically upward). When the connecting plate 22 moves vertically upward, the L-shaped connecting plate 221 can be driven to rotate by the movement sliding groove 222 and the movement sliding block 223 and the universal joint 224 provided on the movement sliding block 223 (the rotating direction of the first cam 23 is counterclockwise in the figure, and the rotating direction of the second cam 231 is clockwise in the figure, and the first cam 23 and the second cam 231 can be rotated under the assistance of the rotating rod 243) ; When the first cam 23 and the second cam 231 are subjected to tension, the rotating rod 243 can be rotated. When the rotating rod 243 rotates, the rotating rod 241 can be driven to rotate. When the rotating rod 241 rotates, the first turnover plate 24 and the second turnover plate 244 can be driven to rotate, so as to adjust the angle of the first turnover plate 24 and the second turnover plate 244; Wherein because the spray head of the water supply pipeline is located above the first turnover plate 24, when the angle of the first turnover plate 24 changes, the sprayed water can be guided to the cutting center of the cutting assembly 16 and the workpiece body under the guidance of the first turnover plate 24, thereby ensuring that the water sprayed during cutting of the cutting assembly 16 can quickly absorb the large amount of heat generated during cutting, control the temperature within a reasonable range, thereby avoiding deformation and performance changes of the workpiece material due to high temperature, and reducing the wear and passivation of the cutting assembly 16 due to overheating, significantly prolonging the service life thereof; At the same time, when the second turnover plate 244 is adjusted, the water can be centrifuged when the cutting tool in the cutting assembly 16 rotates, so that part of the water is flung on the adjusted second turnover plate 244. Because the second turnover plate 244 is provided with a plurality of notches 245, the second turnover plate 244 is in a honeycomb shape, so that when the water is flung on the honeycomb-shaped second turnover plate 244, the water flow can be divided into multiple small water flows by the honeycomb-shaped notches, thereby reducing the impact force and to some extent avoiding the transmission of vibration caused by violent impact to the cutting assembly 16, ensuring that the cutting process is relatively stable; Wherein the sprayed water will flow to the storage box body 131 under the guidance of the water spray cover body 15 and the water baffle 3, and be discharged through the water inlet 133 and the water outlet 134 formed in the bottom of the workbench 13 of the storage box body 131.
