Description

Technical Field

[0001] This utility model relates to the field of flaking device technology, specifically to a high-efficiency flaking device suitable for small-sized, high-hardness products. Background Technology

[0002] CVD diamond possesses excellent thermal conductivity and high mechanical strength, making it a common substrate material for high-power-density electronic devices. It effectively solves the heat dissipation problem of components, and various types of devices fabricated using semiconductor thin-film processing technology are widely used in the electronics, laser, and optical communication industries. Alumina substrates possess excellent electrical insulation, good thermal conductivity, a low and well-matched coefficient of thermal expansion, high mechanical strength, good chemical stability, high surface quality, high temperature resistance, mature processing technology, and relatively low cost, making them ideal materials for manufacturing various types of resistors (thick-film resistors, thin-film resistors).

[0003] For small-sized, high-hardness substrates such as diamond and alumina, high-precision laser cutting equipment is required during processing. However, due to the small size of the devices, subsequent processing is not feasible, so a half-cutting and dicing method is often used. Commonly used dicing fixtures employ manual dicing with slot-type clamps, which is not only inefficient but also causes indentations on the surface metal of the device, and in severe cases, scratches on the metal layer surface, resulting in a low product appearance pass rate. Furthermore, professional dicing equipment is expensive and has high processing costs, thus increasing the overall product manufacturing cost.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

Through the cooperation of the pressure cutter and the positioning block, a portion of the substrate to be diced can be pushed between the pressure cutter and the positioning block via a conveyor plate. The positioning block is vertically adjusted to press the substrate, and the pressure cutter is rotated to achieve flat pressing and dicing of the portion of the substrate. This solves the problem that the existing half-cutting + dicing method is not only inefficient but also causes indentations on the surface metal of the device.

[0008] Optionally, the support frame includes a transverse support plate located above the pressure member. There is a space between the transverse support plate and the pressure member for accommodating the positioning block. A bolt is provided on the transverse support plate and is connected to the positioning block. When the bolt is rotated, it can drive the positioning block to move in the vertical direction. When the positioning block is in contact with the transverse support plate, there is a gap between the positioning block and the pressure knife.

[0009] Optionally, a pusher block is movably provided on the conveyor plate. The pusher block is configured to push the substrate from the first end of the conveyor plate to the last end of the conveyor plate, so that a portion of the substrate to be cleaved enters the gap between the positioning block and the pressure cutter.

[0010] Optionally, the top of the pressure cutter is provided with an upwardly protruding stepped structure, which is configured to limit the length of the substrate to be cleaved at the end of the conveyor plate.

[0011] Optionally, a polytetrafluoroethylene (PTFE) film is laid on the upper surface of the conveyor plate, and a left width limiting member and a right width limiting member are respectively provided on both sides of the PTFE film. The left width limiting member and the right width limiting member are used together to limit the left and right positions of the substrate as it moves on the PTFE film toward the end of the conveyor plate.

[0012] Optionally, both the left and right width limiting members are provided with sliding grooves on the side facing the polytetrafluoroethylene film, and both sides of the pushing block can be inserted into the sliding grooves of the left and right width limiting members respectively. The sliding grooves are configured to restrict the axial sliding of the pushing block within their range.

[0013] Optionally, the push block includes an upper plate and a lower plate, the upper plate being disposed above the lower plate, and the upper and lower plates forming a stepped structure on the side facing the pressure member, with the upper plate protruding outward from the lower plate on the first end side of the conveyor plate.

[0014] Optionally, the push block is provided with an elongated slot for mounting screws, and the conveyor plate is provided with screw holes opening upwards; The screw hole is designed to push the local substrate to be cracked into the gap above the pressure knife, and then the push block is fixed in the preset position on the conveyor plate by screws. The push block and the stepped structure on the top of the pressure knife work together to position the substrate in the head and tail direction of the conveyor plate.

[0015] Optionally, the pressure member is detachably connected to the rotating shaft, and multiple pressure members are provided. The distance between the stepped structure on each pressure member and the end of the conveyor plate is set to be different. The multiple pressure members are configured to adjust the length of the local substrate to be split by replacing the pressure members on the rotating shaft.

[0016] Compared with the prior art, the embodiments of this utility model have the following advantages and beneficial effects: 1. The efficient dicing device for small-sized, high-hardness products provided in this embodiment of the invention, when dicing a small-sized, high-hardness substrate, first places the substrate at the inlet end of the conveyor plate. The substrate is then smoothly conveyed onto the conveyor plate to the dicing position, i.e., between the pressure cutter and the positioning block, via an external drive (manual, cylinder, motor, etc.). At this time, the positioning block moves downward via a vertical adjustment device, pressing a portion of the substrate between the bottom of the positioning block and the top of the pressure cutter. Next, the pressure cutter rotates via a drive device, applying a flat-pressure dicing force to the portion of the substrate pressed between the positioning block and the pressure cutter, dicing the substrate along a predetermined position. After dicing is complete, the positioning block moves upward, releasing the substrate.

[0017] This dicing device achieves efficient flat-press dicing of small-sized, high-hardness substrates through the cooperation of a pressure cutter and a positioning block. Compared with the traditional half-cut + dicing method, this device not only improves dicing efficiency but also avoids indentations or scratches on the surface metal of the device, thereby improving the product's appearance qualification rate.

[0018] 2. This utility model secures the rotating shaft using a first mounting ear and a second mounting ear, ensuring the stability and precision of the rotating shaft. The rotating handle provides a simple and intuitive operating method, facilitating operator control of the cleaving process.

[0019] 3. In this embodiment of the invention, during the cleaving process, the precise vertical adjustment of the positioning block is achieved through the cooperation of the transverse support plate and the bolt. Specifically, the substrate is first placed at the beginning of the conveyor plate. Pushed by the push block, the substrate is smoothly transported to the end of the conveyor plate, allowing a portion of the substrate to be cleaved to enter the gap between the positioning block and the pressure cutter. At this point, the operator rotates the bolt to move the positioning block downwards, pressing the portion of the substrate to be cleaved. The gap between the positioning block and the pressure cutter is used to hold the portion of the substrate to be cleaved. When the positioning block presses the substrate, the gap is filled by the substrate, ensuring accurate and stable positioning of the substrate during the cleaving process. Next, the pressure cutter applies force through the rotation of the rotating shaft, cleaving the substrate along a predetermined position. After cleaving is complete, the positioning block moves upwards by rotating the bolt in the opposite direction, releasing the substrate.

[0020] 4. According to the requirements of the cleaving, a suitable pressure tool can be selected and installed on the rotating shaft. When the part of the substrate to be cleaved contacts the stepped structure on the top of the selected pressure tool, the stepped structure limits the length of the substrate to be cleaved by its height, ensuring that the part of the substrate to be cleaved accurately enters the gap between the positioning block and the pressure tool.

[0021] In general, the efficient dicing device for small-sized, high-hardness products provided by the embodiments of this utility model, through the cooperation of the pressure knife and the positioning block, can push a part of the substrate to be diced between the pressure knife and the positioning block through the conveyor plate. The positioning block is vertically adjusted to press the substrate, and the pressure knife is rotated to achieve flat pressing and dicing of the local substrate, so as to improve the dicing efficiency and reduce indentation.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Example

[0029] Reference Figure 1 As shown, this utility model embodiment provides a high-efficiency chipping device suitable for small-sized, high-hardness products, including a base 1, a support frame 4, a pressing member 5, and a positioning block 6. The base 1 is provided with a conveyor plate 3 for supporting the transmission of the substrate 2; the support frame 4 is disposed on the base 1 and located at the end of the conveyor plate 3; the pressing member 5 is rotatably disposed on the support frame 4; the positioning block 6 is movably disposed above the pressing member 5 and is configured to be vertically adjusted to press the substrate 2 to be chipped partially between the bottom of the positioning block 6 and the top of the pressing member 5; the pressing member 5 is configured to apply force by rotation to flatten and chip the partial substrate 2 pressed between the bottom of the positioning block 6 and the top of the pressing member 5.

[0030] Specifically, the base 1 provides an installation foundation for components such as the conveyor plate 3 and the support frame 4, ensuring the structural stability of the entire device. The conveyor plate 3 supports the transfer of the substrate 2. External thrust transports the substrate 2 to be cleaved from the inlet end of the device to the cleaving position, ensuring that the substrate 2 can accurately reach the predetermined position during processing. The surface of the conveyor plate 3 needs to be smooth and flat to reduce friction and damage to the substrate 2 during transfer. The support frame 4 supports the pressure cutter 5, ensuring that the pressure cutter 5 can remain stable during the cleaving process and accurately apply force to the substrate 2. For example, the support frame 4 is connected to the base 1 by bolts or other fixing methods to ensure its structural stability. The pressure cutter 5 can be mounted on the support frame 4 by bearings or other existing rotating mechanisms, allowing it to rotate freely. The pressing blade 5 applies force by rotating to flatten and crack the substrate 2. The pressing blade 5 is driven by the existing driving device to rotate. When the substrate 2 is pressed against the top of the pressing blade 5 by the positioning block 6, the pressing blade 5 applies force by rotating to crack the substrate 2 along the predetermined position. The shape and size of the pressing blade 5 need to be set according to the size of the substrate 2 and the cracking requirements, and are not limited here.

[0031] The positioning block 6 is used to press the substrate 2 to be cleaved locally between the bottom of the positioning block 6 and the top of the pressing knife 5, ensuring that the substrate 2 is accurately and stably positioned during the cleaving process. The positioning block 6 can be vertically adjusted by existing vertical adjustment devices (such as screws or cylinders).

[0032] When the substrate 2 reaches the cleavage position, the positioning block 6 moves downward, pressing the substrate 2 partially between the bottom of the positioning block 6 and the top of the pressing member 5. The bottom of the positioning block 6 needs to have a certain degree of flatness and hardness to ensure that the substrate 2 will not deform or be damaged during the pressing process. It should be noted that the driving device used to drive the pressing member 5 to rotate can be a motor, or a manually driven structure is not limited here; any existing structure can be used.

[0033] When it is necessary to cleave a small-sized, high-hardness substrate 2, the substrate 2 is first placed at the inlet end of the conveyor plate 3. The substrate 2 is then smoothly conveyed onto the conveyor plate 3 to the cleaving position, i.e., between the pressure cutter 5 and the positioning block 6, via an external drive (manual, cylinder, motor, etc.). At this point, the positioning block 6 moves downward via a vertical adjustment device, locally pressing the substrate 2 between the bottom of the positioning block 6 and the top of the pressure cutter 5. Next, the pressure cutter 5 begins to rotate via a drive device, applying a flat-pressure cleaving force to the substrate 2 pressed between the positioning block 6 and the pressure cutter 5, cleaving the substrate 2 along a predetermined position. After cleaving is complete, the positioning block 6 moves upward, releasing the substrate 2.

[0034] For example, in conjunction with reference Figure 1 , Figure 3 and Figure 4 As shown, the support frame 4 includes a first mounting ear 7 and a second mounting ear 8 located on both sides of the end of the support frame 4, respectively. Both the first mounting ear 7 and the second mounting ear 8 are mounted on the base 1. A rotating shaft 9 is simultaneously provided through the first mounting ear 7 and the second mounting ear 8. A rotating handle 10 is provided on at least one side of the rotating shaft 9, and a pressing member 5 is provided on the rotating shaft 9. When the rotating handle 10 is driven, the rotating shaft 9 can be driven to rotate the pressing member 5. The rotation setting of the rotating shaft 9 can be achieved by setting the through hole to be larger than the outer diameter of the rotating shaft 9 when the first mounting ear and the second mounting ear 8 are connected, thus achieving stable rotation of the rotating shaft 9.

[0035] Specifically, the first mounting ear 7 and the second mounting ear 8 are used to mount the rotating shaft 9, thereby fixing and supporting the pressure cutter 5, ensuring that the pressure cutter 5 remains stable during the cleaving process and can accurately apply force to the substrate 2. The first mounting ear 7 and the second mounting ear 8 can be connected to the base 1 by bolts or other fixing methods to ensure structural stability. The rotating shaft 9 passes through the first mounting ear 7 and the second mounting ear 8 and is connected to the pressure cutter 5. The pressure cutter 5 is located between the first mounting ear 7 and the second mounting ear 8. At least one side of the rotating shaft 9 is provided with a handle. When the rotating handle 10 is driven, the rotating shaft 9 drives the pressure cutter 5 to rotate, realizing the cleaving operation of the substrate 2. The rotating handle 10 facilitates the operator to control the rotation of the pressure cutter 5, providing a simple and intuitive operation method and ensuring the controllability of the cleaving process.

[0036] To further improve the stability of tablet pressing, the support frame 4 includes a transverse support plate 11, which is located above the pressing knife 5. There is a space between the transverse support plate 11 and the pressing knife 5 for accommodating the positioning block 6. A bolt 12 is provided on the transverse support plate 11, which is connected to the positioning block 6. When the bolt 12 is rotated, it can drive the positioning block 6 to move in the vertical direction. When the positioning block 6 is in contact with the transverse support plate 11, there is a gap 13 between the positioning block 6 and the pressing knife 5.

[0037] Specifically, the transverse support plate 11 is used to install and support the positioning block 6, ensuring that the positioning block 6 can move accurately in the vertical direction. The transverse support plate 11 can be connected to the support frame 4 or the base 1 by bolts or other fixing methods to ensure its structural stability. The positioning block 6 is installed in the receiving space between the transverse support plate 11 and the pressing member 5, and is connected to the transverse support plate 11 by bolts 12. The bolts 12 are used to adjust the position of the positioning block 6 in the vertical direction. By rotating the bolts 12, the up and down movement of the positioning block 6 can be precisely controlled to ensure that the substrate 2 is accurately and stably positioned during the cleaving process. It should be noted that the bolts 12 of this utility model can be set to include one or more bolts, which can be set according to actual needs, as long as the purpose of stable adjustment, pressing and cleaving can be achieved. The positioning block 6 is used to press a portion of the substrate 2 to be cleaved between the bottom of the positioning block 6 and the top of the pressing member 5, ensuring that the substrate 2 is accurately and stably positioned during the cleaving process. The positioning block 6 moves vertically by being driven by the bolt member 12. When the positioning block 6 is in contact with the transverse support plate 11, there is a certain gap 13 between the positioning block 6 and the pressing member 5. The gap 13 is used to place the portion of the substrate 2 to be cleaved. When the portion of the substrate 2 to be cleaved is pushed to the gap 13, the bolt member 12 is rotated to move the positioning block 6 downward, pressing the portion of the substrate 2 to be cleaved. Then, the pressing member 5 is rotated to complete the cleaving. This embodiment of the invention achieves precise vertical adjustment of the positioning block 6 through the cooperation of the transverse support plate 11 and the bolt member 12, improving the accuracy and reliability of the cleaving process.

[0038] In a preferred embodiment of this utility model, a pushing block 18 is movably disposed on the conveyor plate 3. The pushing block 18 is configured to push the substrate 2 from the first end to the last end of the conveyor plate 3, so that a portion of the substrate 2 to be cleaved enters the gap 13 between the positioning block 6 and the pressure member 5. In this embodiment, the pushing block 18 is used to push the substrate 2 from the first end to the last end of the conveyor plate 3, ensuring that the portion of the substrate 2 to be cleaved accurately enters the gap 13 between the positioning block 6 and the pressure member 5, thus improving the accuracy and reliability of the substrate 2's transmission. The power source for the pushing block 18 can be manual or mechanical, and is not limited here.

[0039] More preferably, refer to Figure 2As shown, the top of the pressure cutter 5 is provided with an upwardly protruding stepped structure 14. The stepped structure 14 is configured to limit the length of the substrate 2 to be cleaved at the end of the conveyor plate 3. The stepped structure 14 is used to limit the length of the substrate 2 to be cleaved at the end of the conveyor plate 3, ensuring that the length of the cleaved portion of the substrate 2 meets the actual requirements during the cleaving process, thereby ensuring the accuracy and consistency of the cleaving. When the substrate 2 is pushed to the end of the conveyor plate 3 by the pusher block 18, the cleaved portion of the substrate 2 will contact the stepped structure 14. The stepped structure 14 limits the length of the cleaved portion of the substrate 2 by its height, ensuring that the cleaved portion of the substrate 2 accurately enters the gap 13 between the positioning block 6 and the pressure cutter 5. The height of the stepped structure 14 can be designed and adjusted according to the size of the substrate 2 and the cleaving requirements, and is not limited here.

[0040] To improve the flexibility of the device, the pressure cutter 5 is detachably connected to the rotating shaft 9. Multiple pressure cutters 5 are provided, and the distance from the stepped structure 14 on each pressure cutter 5 to the end of the conveyor plate 3 is set differently. The multiple pressure cutters 5 are configured to adjust the length of the local substrate 2 to be cleaved by replacing and mounting them on the rotating shaft 9. This allows for the replacement of pressure cutters 5 of different specifications according to different cleaving requirements, satisfying the cleaving requirements of substrates 2 of different sizes.

[0041] Preferably, a polytetrafluoroethylene film 17 is laid on the upper surface of the conveyor plate 3, and a left width limiting member 15 and a right width limiting member 16 are respectively provided on both sides of the polytetrafluoroethylene film 17. The left width limiting member 15 and the right width limiting member 16 are used together to limit the left and right positions of the substrate 2 on the polytetrafluoroethylene film 17 as it moves toward the end of the conveyor plate 3.

[0042] Specifically, a polytetrafluoroethylene (PTFE) film 17 is laid on the upper surface of the conveyor plate 3 to reduce friction on the substrate 2 during conveying, prevent scratches on the substrate 2, and ensure smooth movement of the substrate 2. Left and right width limiting members 15 and 16 are positioned on either side of the PTFE film 17 to restrict the left and right positions of the substrate 2 during conveying, ensuring smooth movement of the substrate 2 along a predetermined path on the conveyor plate 3 and preventing deviation from the predetermined position. The left and right width limiting members 15 and 16 can be connected to the conveyor plate 3 by bolts or other fixing methods; no restrictions are placed here, as long as sufficient connection stability is achieved.

[0043] To further improve the pushing stability of the pusher block 18, sliding grooves can be provided on the side of the left width limiting member 15 and the right width limiting member 16 facing the polytetrafluoroethylene film 17. Both sides of the pusher block 18 can be inserted into the sliding groove of the left width limiting member 15 and the sliding groove of the right width limiting member 16, respectively. The sliding grooves are configured to restrict the axial sliding of the pusher block 18 within its range, ensuring that the pusher block 18 can push the substrate 2 smoothly and accurately during the transmission process.

[0044] More preferably, the push block 18 includes an upper plate 19 and a lower plate 20. The upper plate 19 is disposed above the lower plate 20, and the upper plate 19 and the lower plate 20 form a stepped structure on the side facing the pressure member 5. The upper plate 19 protrudes outward from the lower plate 20 on the first end side of the conveyor plate 3. This structure allows the push block 18 to contact the substrate 2 more stably when pushing the substrate 2. Furthermore, the upper plate 19 protrudes outward from the lower plate 20 on the first end side of the conveyor plate 3, which facilitates the pushing of the substrate 2.

[0045] Furthermore, the push block 18 is provided with a long slot 22 for mounting screws 21, and the conveyor plate 3 is provided with an upward-facing screw hole; the screw hole is configured to push the partial substrate 2 to be cracked into the gap above the pressure knife 5, and then fix the push block 18 in the preset position of the conveyor plate 3 by screws 21. The push block 18 and the stepped structure 14 on the top of the pressure knife 5 together achieve the positioning of the substrate 2 in the head and tail direction of the conveyor plate 3.

[0046] Specifically, a long slot 22 is provided on the push block 18 for mounting screws 21, allowing the push block 18 to be finely adjusted on the conveyor plate 3 along the direction of the long slot 22 to adapt to different cleaving requirements. The long slot 22 passes through the push block 18 and can be aligned with the screw holes on the conveyor plate 3. By passing the screws 21 through the long slot 22 and screwing them into the screw holes on the conveyor plate 3, the push block 18 can be fixed in the preset position on the conveyor plate 3, further ensuring that the substrate 2 is accurately positioned in the head and tail direction of the conveyor plate 3, and further improving the stability during the cleaving process.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the utility model.
