Description

Technical Field

[0001] This utility model relates to the field of cutting machine tool holder technology, and in particular to a cutting machine tool holder for preventing MLCC cutting discs from sticking together. Background Technology

[0002] In the electronics manufacturing industry, multilayer ceramic capacitors (MLCCs) are a key electronic component with a wide range of applications, covering many fields from smartphones to automotive electronics. In the production process of MLCCs, the cutting process is a crucial link, which directly affects the quality of the product and production efficiency.

[0003] A search revealed Chinese patent CN217476117U, which provides a tool holder for an MLCC cutting machine. The tool holder is designed with multiple detachable parts to achieve fast and stable cutting of products. This MLCC cutting machine tool holder can be removed and the blades can be quickly replaced, which makes up for the problems of difficult tool replacement and poor product cutting stability of traditional tool holders, improves the processing efficiency of the equipment, increases output, and saves time and labor.

[0004] However, during use, it was found that due to the characteristics of ceramic materials and the heat and friction generated during cutting, MLCC wafers tend to stick to the surface of the cutting blade. The usual method is to apply silicone oil to the surface of the cutting blade. When this device applies silicone oil, it is easy to apply too much or too little silicone oil. Applying too much will waste silicone oil, while applying too little will not achieve the ideal anti-sticking effect. The uniformity of the application is poor, and it is difficult to ensure that the cutting blade is effectively protected against sticking. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting machine blade holder for preventing MLCC chip adhesion during cutting. By adjusting the position of the baffle, the amount of silicone oil coating can be controlled to adapt to different cutting conditions, reduce cutting friction and adhesion, reduce MLCC chip adhesion, ensure controllable coating amount, achieve uniform distribution of silicone oil on the blade surface of the cutting blade body, and improve the anti-sticking effect of the cutting blade body.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cutting machine tool holder for preventing MLCC cutting disc adhesion, comprising a tool holder body, a tool groove on the top surface of the tool holder body, a cutting blade body inserted into the tool groove, a storage cavity inside the tool holder body, a gear pump connected to the side wall of the tool holder body, a pressure gauge connected to the tool holder body, two baffles inserted into the tool holder body through a limiting groove, multiple seepage holes on the groove wall, multiple control grooves on the baffles, a push block at the outer end of the tool holder body, a cylinder mounted on the side wall of the tool holder body through a mounting base, one end of the piston rod of the cylinder being fixedly connected to the push block, and a drain pipe with a valve installed on the tool holder body, the drain pipe being connected to the storage cavity.

[0007] Preferably, the gear pump is mounted on the outer wall of the tool holder body via a mounting base, the baffle is slidably connected to the limiting groove, and the delivery end of the gear pump is connected to the storage cavity.

[0008] Through the above technical solution, the gear pump pumps silicone oil into the storage cavity inside the tool holder body.

[0009] Preferably, the upper end of the blade holder body is provided with a cleaning component, the cleaning component includes a support block, there are two support blocks, the bottom surfaces of the two support blocks are respectively fixedly connected to the top surface of the blade holder body, the upper end of the blade holder body is provided with two cleaning rollers, the outer peripheral walls of the two cleaning rollers are respectively rotatably connected to the two support blocks, and the outer ends of the cleaning rollers are in frictional contact with the outer wall of the cutting blade body.

[0010] Through the above technical solution, the outer end of the rotating cleaning roller comes into frictional contact with the outer wall of the cutting blade body, cleaning the MLCC chips, impurities, and excess silicone oil adhering to the surface of the cutting blade body.

[0011] Preferably, a drive gear is fixed at one end of the sweeping roller, the two drive gears mesh with each other, and a drive motor is mounted on the outer wall of one of the support blocks through a mounting base. The output shaft of the drive motor is coaxially connected to one of the sweeping rollers.

[0012] Through the above technical solution, the output shaft of the drive motor drives the cleaning roller connected to it to rotate. Since the drive gears at one end of the two cleaning rollers mesh with each other, the other cleaning roller will rotate synchronously in the opposite direction.

[0013] Preferably, the upper end of the cleaning roller is provided with an arc-shaped block, and the two ends of the arc-shaped block are respectively fixedly connected to the inner walls of two support blocks.

[0014] The above technical solution uses an arc-shaped block to block the debris splashing on the cleaning roller.

[0015] Preferably, an inclined block is provided below the outer side of the arc-shaped block, and a connecting block is fixedly provided on the bottom surface of the inclined block. The two connecting blocks are respectively fixedly connected to the top surface of the tool holder body and the inner wall of the two support blocks.

[0016] The above technical solution uses an inclined block to scrape the cleaning roller, causing the scraped debris to be discharged along the top surface of the inclined block to be collected externally.

[0017] The beneficial effects of this utility model are:

[0018] A gear pump pumps silicone oil into the storage chamber inside the blade holder body. A pressure gauge monitors the pressure inside the storage chamber in real time to ensure stable silicone oil delivery pressure. A cylinder drives a pusher block to move, causing a baffle to slide within a limiting groove. This adjusts the communication area between the seepage hole and the control groove. When the two are fully aligned, the silicone oil, under the pressure of the storage chamber, permeates evenly through the seepage hole into the blade groove and coats the surface of the cutting blade body inside the groove. By adjusting the position of the baffle, the amount of silicone oil coating is controlled to adapt to different cutting conditions. This reduces cutting friction and adhesion, lowers MLCC chip adhesion, ensures controllable coating amount, achieves uniform silicone oil distribution on the blade surface of the cutting blade body, and improves the anti-sticking effect of the cutting blade body.

[0019] The output shaft of the drive motor drives the cleaning roller connected to it to rotate. Since the drive gears at one end of the two cleaning rollers mesh with each other, the other cleaning roller will rotate synchronously in the opposite direction. The outer end of the rotating cleaning roller rubs against the outer wall of the cutting blade body to clean the MLCC chips, impurities and excess silicone oil adhering to the surface of the cutting blade body.

[0020] The debris removed by the cleaning roller moves upward under the rotation of the cleaning roller. The arc-shaped block blocks the debris splashing on the cleaning roller, and the inclined block scrapes the cleaning roller. The scraped debris is discharged along the top surface of the inclined block to the outside for collection. This facilitates the removal of adhering MLCC debris and silicone oil residue, improves production continuity, and promptly peels off incompletely cured silicone oil layers and fine chips. It prevents the accumulation of chips from dulling the cutting blade or causing dimensional deviations in the chips, improves the flatness and dimensional accuracy of the MLCC cutting surface, and provides favorable conditions for silicone oil application.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, this embodiment provides a cutting machine tool holder for preventing MLCC cutting disc adhesion, including a tool holder body 1, a tool groove 2 on the top surface of the tool holder body 1, a cutting blade body 3 inserted into the tool groove 2, a storage cavity 4 inside the tool holder body 1, a gear pump 5 connected to the side wall of the tool holder body 1, a pressure gauge 6 connected to the tool holder body 1, two baffles 7 inserted into the tool holder body 1 through a limiting groove 13, multiple seepage holes 8 on the groove wall of the tool groove 2, multiple control grooves 9 on the baffles 7, a push block 10 at the outer end of the tool holder body 1, a cylinder 11 mounted on the side wall of the tool holder body 1 through a mounting base, one end of the piston rod of the cylinder 11 being fixedly connected to the push block 10, and a drain pipe 12 with a valve installed on the tool holder body 1, the drain pipe 12 being connected to the storage cavity 4.

[0031] The gear pump 5 is mounted on the outer wall of the tool holder body 1 via a mounting base. The baffle 7 is slidably connected to the limiting groove 13. The delivery end of the gear pump 5 is connected to the storage cavity 4. The gear pump 5 pumps silicone oil into the storage cavity 4 inside the tool holder body 1.

[0032] Working principle: Gear pump 5 pumps silicone oil into the storage chamber 4 inside the cutter body 1. Pressure gauge 6 monitors the pressure inside the storage chamber 4 in real time to ensure stable silicone oil delivery pressure (pressure value can be adjusted by the drain pipe 12 valve). The cylinder 11 drives the push block 10 to move, causing the baffle 7 to slide in the limiting groove 13, adjusting the communication area between the seepage hole 8 and the control groove 9. When the two are fully aligned, the silicone oil, under the pressure of the storage chamber 4, permeates evenly into the cutter groove 2 through the seepage hole 8 and coats the surface of the cutting blade body 3 inside the cutter groove 2. By adjusting the position of the baffle 7, the amount of silicone oil coating is controlled to adapt to different cutting conditions. This reduces cutting friction and adhesion, reduces MLCC chip adhesion, ensures controllable coating amount, achieves uniform distribution of silicone oil on the blade surface of the cutting blade body 3, and improves the anti-sticking effect of the cutting blade body 3.

[0033] Example 2

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, based on Embodiment 1, a cleaning assembly 14 is provided at the upper end of the blade holder body 1. The cleaning assembly 14 includes two support blocks 1401. The bottom surfaces of the two support blocks 1401 are fixedly connected to the top surface of the blade holder body 1. Two cleaning rollers 1402 are provided at the upper end of the blade holder body 1. The outer peripheral walls at both ends of the two cleaning rollers 1402 are rotatably connected to the two support blocks 1401. The outer ends of the cleaning rollers 1402 are in frictional contact with the outer wall of the cutting blade body 3. The rotating cleaning rollers 1402 are in frictional contact with the outer wall of the cutting blade body 3 to clean the MLCC chips, impurities, and excess silicone oil adhering to the surface of the cutting blade body 3.

[0035] One end of the sweeping roller 1402 is fixed with a drive gear 1403, and the two drive gears 1403 mesh with each other. A drive motor 1404 is mounted on the outer wall of one of the support blocks 1401 through a mounting base. The output shaft of the drive motor 1404 is coaxially connected to one of the sweeping rollers 1402. The output shaft of the drive motor 1404 drives the sweeping roller 1402 coaxially connected to it to rotate. Since the drive gears 1403 at one end of the two sweeping rollers 1402 mesh with each other, the other sweeping roller 1402 will rotate synchronously in the opposite direction.

[0036] The upper end of the sweeping roller 1402 is provided with an arc-shaped block 1405, and the two ends of the arc-shaped block 1405 are fixedly connected to the inner walls of the two support blocks 1401 respectively; the arc-shaped block 1405 blocks the debris splashed on the sweeping roller 1402.

[0037] An inclined block 1406 is provided on the lower outer side of the arc-shaped block 1405. A connecting block 1407 is fixedly provided on the bottom surface of the inclined block 1406. The two connecting blocks 1407 are fixedly connected to the top surface of the blade holder body 1 and the inner wall of the two support blocks 1401, respectively. The cleaning roller 1402 is scraped by the inclined block 1406, and the scraped debris is discharged along the top surface of the inclined block 1406 to the outside for collection.

[0038] In use, the output shaft of the drive motor 1404 drives the cleaning roller 1402 connected to it to rotate. Since the drive gear 1403 at one end of the two cleaning rollers 1402 meshes with each other, the other cleaning roller 1402 will rotate synchronously in the opposite direction. The outer end of the rotating cleaning roller 1402 rubs against the outer wall of the cutting blade body 3 to clean the MLCC chips, impurities and excess silicone oil adhering to the surface of the cutting blade body 3.

[0039] The debris removed by the cleaning roller 1402 moves upward under the drive of the rotating cleaning roller 1402. The arc-shaped block 1405 blocks the debris splashing on the cleaning roller 1402, and the inclined block 1406 scrapes the cleaning roller 1402. The scraped debris is discharged along the top surface of the inclined block 1406 to the outside for collection. This facilitates the removal of adhering MLCC debris and silicone oil residue, improves production continuity, and promptly peels off incompletely cured silicone oil layers and fine chips. It prevents the accumulation of chips from causing the cutting blade to become dull or the chip size deviation, improves the flatness and dimensional accuracy of the MLCC cutting surface, and provides favorable conditions for silicone oil application.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
