[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1-2 In an embodiment of the present invention, an optical part cutting and cooling device comprises an upper cover plate 1 and a lower cover plate 4, wherein an outer frame 3 is provided on the periphery of the lower cover plate 4, a plurality of upper baffles 6 are provided on the side of the upper cover plate 1 close to the lower cover plate 4, a plurality of lower baffles 7 are provided on the side of the lower cover plate 4 close to the upper cover plate 1, a plurality of accommodating cavities 2 are formed on the lower cover plate 4 by the lower baffles 7, a plurality of first transmission cavities 5 communicating with the accommodating cavities 2 are formed on the upper baffles 6 on the upper cover plate 1, a second transmission cavity 8 communicating with the first transmission cavity 5 is formed between adjacent lower baffles 7, a plurality of discharge cavities 10 communicating with the second transmission cavity 8 are provided on the lower cover plate 4, and a plurality of discharge ports 9 communicating with the discharge cavities 10 are provided on the lower cover plate 4. When in use, the sand liquid enters the accommodating chamber 2, and the sand liquid in the accommodating chamber 2 is slowly dispersed into the second transmission chamber 8 through the first transmission chamber 5, and then enters the discharge chamber 10, and finally dispersed from the discharge port 9 and evenly sprayed onto the cut wafer, which can effectively improve the uniformity of the sand liquid spraying and avoid the problem of cracking of the optical wafer due to uneven cooling during the cutting process.

[0024] In this embodiment, the inner diameter of the second transmission cavity 8 is m2, and the inner diameter of the discharge cavity 10 is m3, where m3<m2. This can further reduce the flow rate of the sand liquid, effectively improve the uniformity of the sand liquid distribution, and further improve the cooling effect.

[0025] In this embodiment, m3 < 1 / 3 m2. In this way, the flow rate of the sand liquid can be further reduced, the uniformity of the sand liquid distribution is effectively improved, and the cooling effect is further improved.

[0026] In this embodiment, the gap between the lower baffle 7 and the upper baffle 6 is m1, 2cm≤m1≤8cm. Specifically in this embodiment, m1 is 5cm, which can further reduce the speed of the sand liquid flow, effectively improve the uniformity of the sand liquid distribution, and further improve the cooling effect.

[0027] In this embodiment, the height of the upper end of the lower baffle 7 protruding from the lower end of the upper baffle 6 is m4, 5mm≤m4≤25mm. Specifically in this embodiment, m4 is 15mm, so that the flow of the sand liquid can be slowed down, thus achieving uniform distribution of the sand liquid and further improving the cooling effect.

[0028] It can be understood that m1 can also be 2cm, 3cm, 4cm, 6cm, 7cm, 8cm, etc.

[0029] It can be understood that m4 can also be 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 11cm, 12cm, 13cm, 14cm, 16cm, 17cm, 18cm, 19cm, 20cm, 21cm, 22cm, 23cm, 24cm, 25cm, etc.

[0030] Example 2

[0031] See also Figure 3-4 The difference between this embodiment and embodiment 1 is that, in this embodiment, two bolt shafts 19 are provided on the outer sides of the upper cover plate 1 and the lower cover plate 4, and bolt sleeves are connected between the bolt shafts 19. One end of the two bolt shafts 19 is provided with an L-shaped limit plate 11, and a first piston 12 is provided on the side of the L-shaped limit plate 11 close to the upper cover plate 1 and the side of the L-shaped limit plate 11 close to the lower cover plate 4. A piston shaft 13 is provided on the side of the first piston 12 close to the upper cover plate 1, and a second piston 14 is installed on the side of the piston shaft 13 away from the first piston 12, and the second piston 14 is installed on the upper cover plate 1. By arranging two bolts on the outer sides of the upper cover plate 1 and the lower cover plate 4, a bolt sleeve is connected between the two bolts, and rotating the bolt sleeve can realize the extension and retraction of the bolt shaft 19 in the vertical direction, so that the L-shaped limit plate 11 can realize the extrusion of the upper cover plate 1 and the lower cover plate 4. During the extrusion process, the piston shaft 13 extends and retracts between the first piston 12 and the second piston 14, and can be adjusted according to the actual size of the cooling device, thereby improving the flexibility of assembly. In addition, the stability and tightness of the installation of the upper cover plate 1 and the lower cover plate 4 are also improved.

[0032] In this embodiment, a spring 15 is provided between the first piston 12 and the second piston 14, and the spring 15 is sleeved on the outer periphery of the piston shaft 13. By providing the spring 15 between the first piston 12 and the second piston 14, and the spring 15 is sleeved on the outer periphery of the piston shaft 13, the elastic restoring force of the spring 15 can be utilized to achieve that when the L-shaped limit plate 11 squeezes the spring 15, the spring 15 generates a reaction force, which can facilitate the assembly of the upper cover plate 1 and the lower cover plate 4 and improve the stability of the installation of the upper cover plate 1 and the lower cover plate 4.

[0033] In this embodiment, a plug hole 18 is provided on one side of the outer frame 3 close to the upper cover plate 1, and a limit shaft inserted in the plug hole 18 is provided on one side of the upper cover plate 1 close to the outer frame 3, and the limit shaft is clearance-matched with the plug hole 18. By providing a plug hole 18 on one side of the outer frame 3 close to the upper cover plate 1, and providing a limit shaft inserted in the plug hole 18 on one side of the upper cover plate 1 close to the outer frame 3, and the limit shaft is clearance-matched with the plug hole 18, the stability of the upper cover plate 1 and the lower cover plate 4 after assembly can be effectively improved, and the convenience of installing the upper cover plate 1 and the lower cover plate 4 is also facilitated.

[0034] In this embodiment, the outer periphery of the limiting shaft is provided with a limiting rib 16, and the inner wall of the insertion hole 18 is provided with a limiting groove 17 for the limiting rib 16 to be inserted. By providing the limiting rib 16 on the outer periphery of the limiting shaft and the limiting groove 17 on the inner wall of the insertion hole 18 for the limiting rib 16 to be inserted, the upper cover plate 1 and the lower cover plate 4 can be prevented from shaking after installation, thereby improving the stability of the cooling device during use.
