Description

Technical Field

[0001] The present invention relates to the technical field of tool processing, and more particularly to a blade processing device. Background Art

[0002] In the current wafer dicing hard knife production process, the worker first inserts the blade into the shaft head at the front end of the spindle, and then uses a nut to firmly press the blade onto the spindle; the spindle rotates at high speed, driving the blade to cut back and forth on the sharpening plate on the workbench to complete the sharpening; after the sharpening is completed, the worker stops the spindle from rotating, removes the nut with a wrench, removes the blade that has been sharpened, and installs a new blade to be sharpened for a new round of blade sharpening operations.

[0003] However, this method of manually tightening the nut to disassemble and assemble the blade has two major disadvantages: first, the efficiency is low. The nut needs to be tightened and loosened when installing and removing the blade. The blade sharpening and grinding only takes 30 seconds, but it takes 60 seconds to disassemble and assemble the blade and tighten the nut. The long auxiliary time seriously reduces the production efficiency; second, it affects the quality of the blade. When tightening and loosening the nut, the nut and the end face of the blade will rub against each other, and leave marks of compression on the end face of the blade. Any tiny scratches on the surface of the blade will affect the imbalance and cause the blade to vibrate, thereby increasing the edge collapse of the cut object and reducing the quality of the blade.

[0042] The core of the present invention is to disclose a blade processing device to improve the efficiency of blade sharpening and ensure the quality of the blade.

[0043] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0044] Combination Figure 1-Figure 6 The blade processing device disclosed in the present invention includes a base 100, an adsorption spindle 200 and a sharpening plate 300. The adsorption spindle 200 is rotatably arranged on the base 100 and is provided with a first adsorption gas path 210. An adsorption fixture 400 is arranged at one end of the adsorption spindle 200. A second adsorption gas path 401 connected to the first end of the first adsorption gas path 210 is opened through the adsorption fixture 400. The adsorption fixture 400 is used to adsorb the blade 600 through the second adsorption gas path 401. The second end of the first adsorption gas path 210 is used to be connected to a vacuum generating device, and the vacuum generating device is used to provide a vacuum adsorption force; the sharpening plate 300 is arranged on the base 100 and is used to grind and sharpen the blade 600.

[0045] During the process of sharpening the blade 600, after starting the vacuum generating device, negative pressure can be formed at the adsorption fixture 400 through the first adsorption air path 210 and the second adsorption air path 401, so that the blade 600 can be adsorbed and fixed, so that the blade 600 can rotate with the adsorption spindle 200, and finally the blade 600 is sharpened by the sharpening plate 300. After the sharpening is completed, the vacuum generating device can be turned off to remove the blade 600.

[0046] Compared with the prior art, the blade processing device disclosed in the present invention adopts a vacuum adsorption method to fix the blade 600, and no nut is required for locking. The disassembly and assembly process of the blade 600 is quick and convenient, which improves the sharpening efficiency of the blade 600. At the same time, the vacuum adsorption method is used to fix the blade 600 to avoid friction between the nut and the blade 600 and scratches on the blade 600, thereby ensuring the dynamic balance quality and appearance of the blade 600, ensuring the sharpening effect, reducing the vibration of the blade 600 during rotation, reducing the risk of blade 600 cutting edge cracking, and ensuring the quality of the blade 600.

[0047] In a further optimized solution, a first guide rail 110 is provided on the base 100, a first sliding seat 111 is slidably provided on the first guide rail 110, and the sharpening plate 300 is provided on the first sliding seat 111. Specifically, the sliding of the first sliding seat 111 on the first guide rail 110 can be achieved by a belt drive, a cylinder / electric cylinder / hydraulic cylinder push-pull or other driving method. The sharpening plate 300 can be provided on the first sliding seat 111 by a detachable method such as vacuum adsorption, so as to facilitate the adjustment of the position of the sharpening plate 300 and the replacement of the sharpening plate 300.

[0048] During the sharpening process of the blade 600, after the blade 600 is mounted on the adsorption spindle 200, the adsorption spindle 200 drives the blade 600 to rotate, and then the first sliding seat 111 moves on the first guide rail 110 to make the sharpening plate 300 pass through the sharpening position of the blade 600, and at the same time, the blade 600 leaves a sharpening groove on the sharpening plate 300 parallel to the extension direction of the first guide rail 110. Compared with the technical solution in which the sharpening plate 300 is fixed, the present invention can make the sharpening point height of the blade 600 consistent through the movement of the sharpening plate 300, that is, it can ensure that the sharpening thickness of each part of the blade 600 in the circumferential direction remains uniform, thereby improving the sharpening quality of the blade 600.

[0049] In a specific embodiment disclosed in the present invention, a second guide rail 120 is provided on the base 100, and a second sliding seat 121 is movably provided on the second guide rail 120; a lifting guide rail 130 is provided on the second sliding seat 121, and a lifting sliding seat 131 is slidably provided on the lifting guide rail 130, and the adsorption spindle 200 is rotatably provided on the lifting sliding seat 131; the extension directions of any two of the first guide rail 110, the lifting guide rail 130 and the second guide rail 120 are perpendicular, and by adjusting the position of the second sliding seat 121 on the second guide rail 120 and the position of the lifting sliding seat 131 on the lifting guide rail 130, the adsorption spindle 200 can be brought close to the sharpening plate 300 for grinding and sharpening. When sharpening the blade 600, the second sliding seat 121 moves along the second guide rail 120 in the direction of the first guide rail 110, so that the adsorption spindle 200 reaches a position close to the movement trajectory of the sharpening plate 300, and then the lifting sliding seat 131 slides along the lifting guide rail 130 to a height position close to the sharpening plate 300 until the blade 600 on the adsorption spindle 200 contacts and cuts the sharpening plate 300, and at the same time, the first sliding seat 111 drives the sharpening plate 300 to translate along the first guide rail 110, so that the blade 600 cuts a straight sharpening groove on the sharpening plate 300.

[0050] The present invention configures the position moving structure of the blade 600 during the sharpening process on the adsorption spindle 200 and the sharpening plate 300 respectively. Compared with the solution of integrating the moving structure entirely on the adsorption spindle 200, the structure is simplified, the load of the driving mechanism in the moving structure is reduced, the production cost is reduced, and the moving accuracy of the relative position of the adsorption spindle 200 and the sharpening plate 300 is ensured. Specifically, the sliding of the second sliding seat 121 on the second guide rail 120 and the sliding of the lifting sliding seat 131 on the lifting guide rail 130 can be achieved by driving methods such as belt transmission, cylinder / electric cylinder / hydraulic cylinder push-pull, etc., which will not be repeated here.

[0051] In a specific embodiment disclosed in the present invention, the first adsorption gas path 210 includes an axial gas path 211 and a radial gas path 212; the axial gas path 211 extends along the axial direction of the adsorption main shaft 200, and the radial gas path 212 extends along the radial direction of the adsorption main shaft 200, and one end of the radial gas path 212 is connected to the axial gas path 211, and the other end is connected to the second adsorption gas path 401. When the vacuum generating device is started, the adsorption fixture 400 is vacuumed and the blade 600 is adsorbed through the axial gas path 211, the radial gas path 212 and the second adsorption gas path 401. Exemplarily, the diameter of the axial gas path 211 can be set to 5mm±0.5mm, and the diameter of the radial gas path 212 can be set to 2mm±0.5mm.

[0052] In order to ensure uniform adsorption of various positions of the blade 600, the radial air paths 212 are multiple and evenly arranged axially around the adsorption main shaft 200, and the second adsorption air paths 401 are multiple and evenly arranged axially around the adsorption fixture 400. The adsorption main shaft 200 and the adsorption fixture 400 are coaxially arranged, and the radial air paths 212 and the second adsorption air paths 401 are connected one by one.

[0053] Combination Figure 4 In order to increase the adsorption area and ensure reliable adsorption of the blade 600, an adsorption annular groove 402 is provided on one end surface of the adsorption fixture 400. The adsorption annular groove 402 is annular and coaxially arranged with the adsorption spindle 200 and connected with each second adsorption gas path 401. The adsorption fixture 400 is used to adsorb the blade 600 through the adsorption annular groove 402. Exemplarily, the depth of the adsorption annular groove 402 can be set to 1mm±0.5mm to ensure sufficient vacuum airflow storage, so that the negative pressure formed can stably adsorb the blade 600 on the adsorption fixture 400.

[0054] In order to facilitate the connection with the vacuum generating device, the blade processing device further includes a transmission shaft 520 and a vacuum connector 510. Figure 3 and Figure 5A mounting seat 500 is provided on the base 100, and the adsorption spindle 200 is rotatably provided on the mounting seat 500 through a bearing (not shown in the figure), and a mounting hole 502 is provided through the mounting seat 500. The vacuum connector 510 is rotatably provided on the mounting seat 500, and one end of the vacuum connector 510 is provided in the mounting hole 502. The first adsorption gas path 210 is connected with the vacuum generating device through the vacuum connector 510; a connecting gas path 521 is provided axially through the transmission shaft 520, a first end of the transmission shaft 520 is connected with the adsorption spindle 200, and a second end is connected with the vacuum connector 510, so that the vacuum connector 510 can rotate with the adsorption spindle 200, and both ends of the connecting gas path 521 are respectively connected with the inner holes of the first adsorption gas path 210 and the vacuum connector 510. During the installation of the blade 600 , the vacuum generating device sequentially forms negative pressure at the end surface of the adsorption fixture 400 through the vacuum connector 510 , the connecting air path 521 , the first adsorption air path 210 and the second adsorption air path 401 to adsorb the blade 600 .

[0055] Specifically, the vacuum connector 510 is used to connect with the vacuum generating device through a rotating bearing (not shown in the figure). During the rotation of the adsorption spindle 200, the rotational power of the adsorption spindle 200 is transmitted to the vacuum connector 510 through the transmission shaft 520, and the vacuum connector 510 releases the rotational power through the rotating bearing to avoid twisting the vacuum pipeline between the vacuum generating device and the vacuum connector 510.

[0056] Since the adsorption spindle 200 will drive the vacuum joint 510 to rotate at high speed, in order to avoid overheating of the rotating bearing, Figure 5 A cooling air inlet hole 512 is provided on the vacuum joint 510, and cooling gas can be introduced into the cooling air inlet hole 512 to cool the vacuum joint 510, thereby preventing the vacuum joint 510 and the rotating bearing from overheating.

[0057] In one embodiment, the first end of the transmission shaft 520 is threadedly connected to the first adsorption gas path 210. Figure 6 , a first profile is provided on the circumferential outer wall of the second end of the transmission shaft 520, and a second profile is provided on the inner hole wall of the vacuum joint 510, which is opposite to the first profile and in transmission cooperation. During the assembly process, the first end of the transmission shaft 520 is first threadedly installed on the adsorption spindle 200, and then the vacuum joint 510 is installed in the mounting hole 502, and the second end of the transmission shaft 520 is inserted into the vacuum joint 510, so that the first profile and the second profile are arranged oppositely, and finally the vacuum joint 510 is fixed to the mounting seat 500. For example, Figure 6 A technical solution is shown in which eight first profiles are connected end to end on the circumferential outer wall of the second end of the transmission shaft 520, and eight second profiles are connected end to end on the inner hole wall of the vacuum joint 510.

[0058] In order to ensure stable adsorption of the blade 600, a seal 522 is provided between the second end of the transmission shaft 520 and the vacuum joint 510. The seal 522 includes but is not limited to a sealing ring, a sealing gasket, etc., to achieve a sealed connection between the transmission shaft 520 and the vacuum joint 510. Accordingly, a sealing ring groove can be provided on the inner hole wall of the vacuum joint 510 to facilitate the positioning and installation of the seal 522.

[0059] In order to reduce the vibration caused by the geometric error and assembly error between the vacuum joint 510 and the adsorption spindle 200, Figure 5 In some embodiments, the vacuum joint 510 is arranged on the mounting seat 500 through the mounting clamp 501; a floating slot 511 is arranged on the circumferential outer wall of the vacuum joint 510, and the mounting clamp 501 can be slidably engaged in the floating slot 511 and connected to the mounting seat 500. During the assembly process, the mounting clamp 501 and the mounting seat 500 are fixed by screw connection or the like. During the rotation of the adsorption spindle 200, the vacuum joint 510 can float and form a balance relative to the mounting clamp 501, the mounting seat 500 and the adsorption spindle 200 through the floating slot 511, so as to avoid causing vibration tolerance of the adsorption spindle 200 and affecting the sharpening of the blade 600.

[0060] Combination Figure 4 The adsorption fixture 400 is provided with a through hole for being mounted on the end of the adsorption main shaft 200. The connection between the adsorption fixture 400 and the adsorption main shaft 200 can be mechanically contact-sealed by precision machining to avoid leakage at the connection position between the first adsorption gas path 210 and the second adsorption gas path 401.

[0061] In order to facilitate the positioning and installation of the blade 600, Figure 4 A positioning protrusion 403 for the inner hole of the blade 600 to pass through is provided on the adsorption fixture 400. Exemplarily, the length of the positioning protrusion 403 may be 2 mm ± 0.5 mm.

[0062] To further optimize the solution, an external thread is provided on the outer wall of the end of the positioning protrusion 403 away from the adsorption fixture 400, and the external thread on the positioning protrusion 403 is used for threaded connection with a disassembly tool, so as to facilitate the disassembly and assembly of the adsorption fixture 400 on the adsorption spindle 200 by means of the disassembly and assembly tool.

[0063] In a specific implementation process, the vacuum passes through the vacuum generating device along the axial direction of the adsorption spindle 200 through the first adsorption gas path 210 to reach the adsorption fixture 400. After passing through the second adsorption gas path 401 on the adsorption fixture 400, a vacuum negative pressure cavity is formed at the adsorption ring groove 402 on the end face of the adsorption fixture 400, thereby generating a vacuum adsorption force to fix the blade 600. At this time, the adsorption spindle 200 rotates at 40,000 rpm or other speeds to complete the sharpening of the blade 600. After the sharpening of the blade 600 is completed, the connection between the adsorption spindle 200 and the vacuum generating device is temporarily cut off, the sharpened blade 600 is removed, and a new blade 600 to be sharpened is installed on the adsorption fixture 400. At this time, the connection between the adsorption spindle 200 and the vacuum generating device is restored, and the next round of blade 600 sharpening can be performed.

[0064] The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present invention. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. The specific technical means in some embodiments can be combined in part or in whole into another embodiment without being explicitly excluded by another embodiment. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
