Description

Technical Field

[0001] This utility model relates to the field of dicing machine technology, and in particular to a flange assembly and a dicing machine. Background Technology

[0002] During operation, dicing machines typically require changing the appropriate blades based on the characteristics of the product. The flange assembly, including the blades, usually does not need cleaning. However, during the blade replacement process between two flanges, there is a possibility that fine debris or other foreign matter, which is not easily visible to the naked eye, may adhere to the clamping surface. Operators may find it difficult to detect the presence of these fine debris, resulting in a loose fit between the blade and the flange. This can easily lead to gaps between the blade and the clamping surface, causing the blade to wobble during cutting. Consequently, the dicing machine's accuracy may be reduced, the blade's wobble angle may exceed tolerances, and the blade's lifespan may be shortened, ultimately resulting in compromised cutting quality. Utility Model Content

[0003] This utility model provides a flange assembly and a dicing machine, the purpose of which is to reduce the possibility of fine debris between the clamping surface of the flange and the blade in the flange assembly, so as to improve the cutting accuracy of the dicing machine.

[0004] To achieve the above objectives, this utility model provides a flange assembly, comprising:

[0005] The blade is configured to perform dicing operations;

[0006] There are two flanges, and the blade is clamped between the two flanges. The surface of the flange near the blade is defined as the clamping surface. The clamping surface includes a first region and a second region. The second region surrounds the outer periphery of the first region. The first region is coated with a chip-removing layer. The second region has a chip guide groove. One end of the chip guide groove is connected to the first region, and the other end of the chip guide groove is connected to the outside.

[0007] In one embodiment, the chip guide groove includes a first sub-groove and a second sub-groove that are interconnected. The first sub-groove is configured in a petal shape and arranged symmetrically in a ring. One end of the first sub-groove is connected to the first region, and the other end of the first sub-groove is connected to the second sub-groove. The second sub-groove is connected to the outside world.

[0008] In one embodiment, the depth of the second sub-slot is greater than or equal to the depth of the first sub-slot.

[0009] In one embodiment, the first region further has a protrusion disposed within the first sub-groove, the protrusion being able to fit against the blade.

[0010] In one embodiment, there are multiple chip guide grooves, which are arranged in a ring-shaped interval on the outer periphery of the first region.

[0011] In one embodiment, the second region is coated with the desiccant layer.

[0012] The second aspect of this utility model provides a dicing machine, comprising:

[0013] The flange assembly described in any of the foregoing embodiments;

[0014] A drive shaft, connected to the flange assembly, is configured to drive the flange assembly to rotate so that the blade can perform dicing.

[0015] The above-mentioned solution of this utility model has the following beneficial effects:

[0016] In this embodiment, the fine debris in the first region, which experiences less centrifugal force, can gradually move to the second region by relying on the relatively smooth chip layer. Most of the fine debris in the second region, which experiences greater centrifugal force, can be discharged to the external environment through the chip guide groove. This reduces the number of fine debris in the flange assembly, reduces the possibility of gaps between the clamping surface and the blade, and allows the clamping surface of the blade and the flange to fit more tightly. This reduces the possibility of the blade wobbling during cutting, which is beneficial to improving the cutting accuracy of the blade and also improves the service life of the flange assembly.

[0025] This application provides a flange assembly, including a blade 2 and a flange member. The blade 2 is configured to perform dicing processing; please refer to [reference needed]. Figure 2 The blade 2 can be annular. There are two flanges, and the blade 2 is clamped between them. Under the clamping of the two flanges, the blade 2 can be driven by the flanges to rotate at high speed for dicing. Please refer to [link to relevant documentation]. Figure 1The surface of the flange near the blade 2 is defined as the clamping surface 1. The clamping surface 1 can also be annular to match the shape of the blade 2. The clamping surface 1 includes a first region 11 and a second region 12. The second region 12 surrounds the outer periphery of the first region 11. The first region 11 is coated with a chip-removing layer 13. The surface of the chip-removing layer 13 is relatively smooth, so that fine debris is not easily attached to the area of ​​the first region 11, reducing the possibility of fine debris in the first region 11. When the flange assembly rotates at high speed, for example, at a speed greater than or equal to 3000 rpm, the fine debris located in the first region 11 can also be moved outward by the relatively smooth chip-removing layer 13 under the action of centrifugal force. For example, the material of the chip-removing layer 13 can be polytetrafluoroethylene (PTFE). PTFE has a coefficient of friction less than or equal to 0.05 and has good hydrophobic, oleophobic, and fine debris-removing properties. The second region 12 has a chip guide groove 121, which allows fine debris located in the second region 12 to enter the chip guide groove 121 under the action of centrifugal force. One end of the chip guide groove 121 is connected to the first region 11, allowing fine debris located in the first region 11 to enter the chip guide groove 121 under the action of centrifugal force. The other end of the chip guide groove 121 is connected to the outside, allowing the fine debris collected in the chip guide groove 121 to be discharged into the external environment under the action of centrifugal force, which is beneficial for the flange assembly to achieve self-cleaning.

[0026] For example, fine debris is randomly located in the first region 11 and / or the second region 12, with the second region 12 surrounding the outer periphery of the first region 11. The first region 11 is closer to the rotation center of the flange assembly, such that the centrifugal force on the fine debris in the first region 11 is less than that on the fine debris in the second region 12. Therefore, a chip-reducing layer 13 is coated in the first region 11 to reduce the resistance to the movement of the fine debris in the first region 11 towards the second region 12 under the action of centrifugal force. When the flange assembly rotates at high speed, the fine debris in the first region 11 gradually moves towards the second region 12 under the action of centrifugal force, relying on the relatively smooth chip-reducing layer 13. Some of it can directly enter the chip guide groove 121, while the other part enters the area of ​​the second region 12 other than the chip guide groove 121. Under the influence of a large centrifugal force, most of the fine debris located in the second region 12 can gradually move into the chip guide groove 121 and be discharged into the external environment through the chip guide groove 121. A small portion is directly thrown out to the outside, thereby reducing the number of fine debris in the flange assembly and reducing the possibility of gaps between the clamping surface 1 and the blade 2.

[0027] In this embodiment, the fine debris in the first region 11, which experiences less centrifugal force, can gradually move to the second region 12 by relying on the relatively smooth chip layer 13. Most of the fine debris in the second region 12, which experiences greater centrifugal force, can be discharged to the external environment through the chip guide groove 121. This reduces the number of fine debris in the flange assembly, reduces the possibility of gaps between the clamping surface 1 and the blade 2, and allows the clamping surface 1 of the blade 2 and the flange to fit more tightly. This reduces the possibility of the blade 2 wobbling during cutting, which is beneficial to improving the cutting accuracy of the blade 2 and also improves the service life of the flange assembly.

[0028] In one embodiment, please refer to Figure 1 The chip guide groove 121 includes a first sub-groove 1211 and a second sub-groove 1212 that are interconnected. The first sub-groove 1211 is configured in a petal shape and arranged in a ring symmetrical manner to improve the capacity of the first sub-groove 1211 to accommodate fine debris. One end of the first sub-groove 1211 is connected to the first region 11, so that the first sub-groove 1211 can be used to additionally accommodate fine debris that moves from the first region 11 to the chip guide groove 121, so that the fine debris can enter the first sub-groove 1211 more quickly. The other end of the first sub-groove 1211 is connected to the second sub-groove 1212, and the second sub-groove 1212 is connected to the outside. For example, the second sub-groove 1212 can be arranged radially along the clamping surface 1 so that the fine debris collected in the chip guide groove 121 can be discharged to the external environment more smoothly.

[0029] It is understood that the chip guide groove 121 is not limited to including a first sub-groove 1211 and a second sub-groove 1212 that are configured in a petal shape and are interconnected. Exemplarily, the chip guide groove 121 may be a through groove with a constant cross-section arranged radially along the clamping surface 1.

[0030] In one embodiment, the depth of the second sub-groove 1212 is greater than or equal to the depth of the first sub-groove 1211, so that the deeper second sub-groove 1212 allows the fine debris collected in the chip guide groove 121 to pass through more smoothly into the external environment during the discharge of fine debris through the second sub-groove 1212. For example, the depth of the first sub-groove 1211 can be 0.2 mm, and the depth of the second sub-groove 1212 can be 0.3 mm.

[0031] In one embodiment, please refer to Figure 1The second region 12 also has a protrusion 122, which is disposed within the first sub-groove 1211 and can fit against the blade 2. The petal-shaped first sub-groove 1211 has a large area, which reduces the clamping force of the clamping surface 1 on the blade 2. The protrusion 122 is disposed within the first sub-groove 1211, which increases the contact area between the clamping surface 1 and the blade 2 without affecting the entry of fine debris into the first sub-groove 1211, thereby improving the clamping force of the clamping surface 1 on the blade 2 and reducing the possibility of the blade 2 rotating relative to the flange.

[0032] In one embodiment, please refer to Figure 1 The number of chip guide grooves 121 is multiple. The multiple chip guide grooves 121 are arranged in a ring-shaped interval on the outer periphery of the first region 11 so that the fine debris on the clamping surface 1 can enter the chip guide grooves 121 as much as possible under the action of centrifugal force, and then be discharged to the external environment through the chip guide grooves 121, thereby reducing the possibility of gaps between the clamping surface 1 and the blade 2.

[0033] In one embodiment, please refer to Figure 2 The second region 12 is coated with the chip-removing layer 13, which makes it easier for fine debris located in the second region 12 to be directly discharged into the external environment, or to move into the chip guide groove 121 and then be discharged into the external environment, reducing the possibility of gaps between the clamping surface 1 and the blade 2.

[0034] In one embodiment, the flange and the blade 2 can also be configured to magnetically engage, so that during the replacement of the blade 2, the blade 2 can maintain better contact with the clamping surface 1, reducing the possibility of fine debris adhering to the clamping surface 1 and reducing the possibility of gaps between the clamping surface 1 and the blade 2.

[0035] In one embodiment, during the replacement of the blade 2, a flashlight capable of emitting green light can be used to illuminate the clamping surface 1 or the blade 2. The green light can help the operator discover fine debris that is not easily detected under normal visible light, so that the fine debris attached to the blade 2 and / or the clamping surface 1 can be better removed by the operator in advance, reducing the possibility of gaps between the clamping surface 1 and the blade 2.

[0036] The second aspect of this application provides a dicing machine, including the flange assembly and drive shaft of the foregoing embodiments. The drive shaft is connected to the flange assembly, for example, by a flange connection. The drive shaft is configured to drive the flange assembly to rotate so that the blade 2 can perform dicing processing. It also allows fine debris located in the flange assembly to be discharged to the external environment through the chip guide groove 121 under the action of centrifugal force, reducing the possibility of gaps between the clamping surface 1 and the blade 2, and improving the cutting accuracy and service life of the dicing machine.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
