Description

Technical Field

[0001] The present invention relates to the technical field of copper substrate cutting, and specifically to a cutting device and method for processing multi-layer thermoelectric separation copper substrates. Background Art

[0002] A multi-layer thermoelectric separation copper substrate is a circuit board applied to electronic devices, which realizes efficient heat dissipation and stable electrical conduction through special structures and processes to meet the requirements of high-power electronic devices.

[0003] In order to meet the usage requirements of multi-layer thermoelectric separation copper substrates, after the copper substrates are produced, it is usually necessary to cut the copper substrates. However, the existing copper substrate cutting devices lack a cleaning mechanism for the copper substrates before cutting. When the copper substrates are produced, processed, and transported, dust and metal debris may remain on their surfaces. If these impurities are not cleaned before cutting and cutting is directly carried out, the debris and impurities may be embedded between the saw blade teeth, changing the cutting trajectory of the saw blade, causing the cutting path to deviate, resulting in inaccurate cutting dimensions of the copper substrates. At the same time, the existing cutting devices also lack a cooling mechanism for the cutting saw blades. When the saw blades cut the copper substrates at high speed, the saw blades are in close contact with the copper substrates and generate intense friction, causing the temperature of the saw blades to rise sharply. If the saw blades are not cooled, a large amount of heat will be transferred to the copper substrates, causing the local temperature of the copper substrates to be too high, resulting in deformation of the copper substrates. At the same time, after the existing cutting devices cut the copper substrates, it is usually necessary to polish the cut edges. However, the existing cutting devices generally do not have a polishing mechanism. Therefore, after the existing cutting devices finish cutting the copper substrates, it is also necessary to polish them with an external polishing device, which is time-consuming and affects the cutting efficiency.

[0019] A notch 13 is opened at the bottom of the bottom box 10. Limiting grooves 15 are opened on both sides of the bottom of the bottom box 10. A moving member 17 is jointly slidably connected inside the two limiting grooves 15. A plurality of cleaning brushes 18 are fixedly connected to the outer side wall of the moving member 17. A return spring 16 is arranged inside the limiting groove 15. The other end of the return spring 16 is fixedly connected to the outer side wall of the moving member 17. A pushing rod 19 is fixedly connected to the outer side wall of the moving member 17. The pushing rod 19 slidably penetrates through the notch 13 to the inside of the bottom box 10. A driving plate 26 is fixedly connected to the outer side wall of the pushing rod 19. The driving plate 26 is located directly beside the cam 25. A temperature reduction and grinding mechanism is arranged inside the bottom box 10; The temperature reduction and grinding mechanism includes two fixing members 20 fixedly connected inside the bottom box 10. Trigger boxes 22 are fixedly connected to the outer side walls of the two fixing members 20. The two trigger boxes 22 are respectively located on both sides of the cutting saw blade 12. A moving plate 23 penetrates and is slidably connected inside each of the two trigger boxes 22. A trigger magnet 27 is fixedly connected to one end of the moving plate 23 located inside the trigger box 22. The end of the moving plate 23 far from the trigger box 22 is fixedly connected to the outer side wall of the pushing rod 19.

[0020] A driving motor 41 is fixedly connected to the outer side wall of the bottom box 10. The output end of the driving motor 41 is provided with a transmission rod 24. The transmission rod 24 rotates through to the inside of the bottom box 10. A cam 25 is fixedly sleeved on the outer side wall of the transmission rod 24. The end of the transmission rod 24 far from the cam 25 is fixedly connected to a cutting saw blade 12. The cutting saw blade 12 rotates through the notch 13 to the outside of the bottom box 10.

[0021] A sponge 31 is slidably connected through the interior of the trigger box 22. One end of the sponge 31 located inside the trigger box 22 is fixedly connected to a side plate 29.

A contact magnet 28 is fixedly connected to the outer side wall of the side plate 29, and the magnetic pole of the contact magnet 28 is the same as that of the trigger magnet 27.

[0022] In this embodiment, during use, first, the operator can place the copper substrate to be cut on the placement table 3. After the copper substrate is placed on the placement table 3, the electric rod 8 can be controlled to contract, thereby driving the pressing plate 9 to move downward to press and fix the copper substrate on the placement table 3. After the copper substrate is pressed and fixed by the pressing plate 9, at this time, the operator can turn on the starting motor 5 to drive the reciprocating lead screw 6 to rotate. When the reciprocating lead screw 6 rotates, it will drive the bottom box 10 to move from left to right through the transverse moving member 7 for reference Figure 2 When the bottom box 10 is driven by the transverse moving member 7 and the cutting saw blade 12 at its bottom is about to contact the copper substrate, at this time, the operator can turn on the driving motor 41 to drive the transmission rod 24 to rotate. When the transmission rod 24 rotates, it will drive the cam 25 to strike the driving plate 26. When the driving plate 26 is struck, it will drive the moving member 17 to move in the limiting groove 15 through the push rod 19. Under the action of the elastic force of the return spring 16 and the intermittent strike of the cam 25, the moving member 17 will drive the cleaning brush 18 to perform a reciprocating motion. When the cleaning brush 18 performs a reciprocating motion, it will scrape and clean the surface of the contacted copper substrate to prevent dust and metal debris from remaining on the surface of the copper substrate, which may affect the cutting accuracy of the subsequent cutting saw blade 12.

[0023] Embodiment Two: Refer to Figures 1-10 A plurality of top plates 32 are fixedly connected to the outer side wall of the trigger box 22. A control member 33 is fixedly connected to each of the plurality of top plates 32. A baffle 35 is slidably connected inside the control member 33. A circulation hole 36 is formed in the baffle 35. One end of the baffle 35 close to the moving plate 23 is fixedly connected to the side plate 29. A telescopic tube 34 is communicated and arranged at the bottom of the control member 33, and one end of the telescopic tube 34 away from the control member 33 is communicated to the inside of the sponge 31.

[0024] A water delivery pipe 21 is communicated with one end of each of the plurality of control members 33 away from the telescopic tube 34.

[0025] Two limiting rods 39 are fixedly connected to the inside of the bottom box 10. Pressure springs 38 are sleeved on both of the two limiting rods 39. An inner plate 37 is slidably sleeved on the two limiting rods 39 together. A grinding plate 14 is fixedly connected to the outer side wall of the inner plate 37. The grinding plate 14 penetrates through the notch 13 to the outside of the bottom box 10. A moving plate 40 is fixedly connected to the outer side wall of the inner plate 37, and the moving plate 40 is located directly to the side of the cam 25.

[0026] In this embodiment, when the moving member 17 reciprocates, while cleaning the surface of the copper substrate through the cleaning brush 18, it will also drive the moving plate 23 to move synchronously through the push rod 19. When the moving plate 23 reciprocates inside the trigger box 22, the trigger magnet 27 will come to the front side of the contact magnet 28. When the trigger magnet 27 comes to the front side of the contact magnet 28, the distance between the two becomes closer at this time. Under the repulsive magnetic force, the side plate 29 will push the sponge 31 to move away from the fixing member 20 against the elastic force of the plurality of pressing springs 30 and contact the surface of the cutting saw blade 12. When the side plate 29 pushes the sponge 31 to move away from the fixing member 20, it will also push the baffle 35 to move synchronously, so that the flow hole 36 originally located outside the control member 33 enters the control member 33. When the flow hole 36 enters the control member 33, the water in the water tank 11 conveyed by the water delivery pipe 21 will first pass through the flow hole 36 and then be conveyed to the sponge 31 through the telescopic pipe 34 for adsorption by the sponge 31. When the sponge 31 adsorbs water inside, when it contacts the surface of the cutting saw blade 12, it will wipe the adsorbed water inside the sponge 31 onto the surface of the cutting saw blade 12 to cool the cutting saw blade 12 and prevent the cutting saw blade 12 from generating high temperature when cutting the surface of the copper substrate.

[0027] Driven by the transmission rod 24, in addition to knocking the driving plate 26, the cam 25 will also knock the moving plate 40. Under the intermittent knocking of the cam 25 and the elastic force of the pressure spring 38, the inner plate 37 will drive the grinding plate 14 to reciprocate. Since the grinding plate 14 is located behind the cutting saw blade 12, after the cutting saw blade 12 finishes cutting the copper substrate, the grinding plate 14 will enter the cut made by the cutting saw blade 12 and reciprocate to grind the cut to prevent burrs from remaining on the cutting surface of the copper substrate, ensuring the cutting effect and improving the cutting efficiency of the entire device at the same time.

[0028] A method for using a cutting device for processing a multi-layer thermoelectric separation copper substrate, the method comprising the following steps; S1: During use, first, the operator places the copper substrate to be cut on the placement table 3. After the copper substrate is placed on the placement table 3, the cutting mechanism will press and fix the copper substrate placed on the placement table 3; S2: After the copper substrate is pressed and fixed by the pressing plate 9, the cutting mechanism will move and cut the copper substrate; S3: When cutting the copper substrate, the mechanism inside the bottom box 10 will also clean the area to be cut of the copper substrate; S4: While cleaning the copper substrate, the mechanism inside the bottom box 10 will also cool the cutting mechanism and grind the cut of the copper substrate.

[0029] It should be noted that since the pressing spring 30 is a damping spring, its contraction speed is normal while its rebound speed is slow. Due to the relatively fast rotation speed of the transmission rod 24, the frequency at which the cam 25 knocks on the driving plate 26 is relatively high. When the driving plate 26 causes the moving plate 23 to reciprocate at a high frequency inside the trigger box 22 through the push rod 19, the trigger magnet 27 will also intermittently be located directly beside the contact magnet 28 at an extremely high frequency. When the trigger magnet 27 moves away from directly beside the contact magnet 28 along with the moving plate 23, the pressing spring 30 with a slow rebound speed is not fast enough to spring the side plate 29 and the baffle 35 back to their original positions. And then, driven by the moving plate 23 at a high frequency, the trigger magnet 27 will come back to the side of the contact magnet 28 again. Therefore, as long as the moving plate 23 reciprocates at a high frequency inside the trigger box 22, it will continuously push the side plate 29 to move away from the fixing member 20 through the repulsive magnetic force, and correspondingly, the flow hole 36 will also always be inside the control member 33.

[0030] It should be noted that when the sponge 31 wipes the water adsorbed inside it onto the surface of the cutting saw blade 12, no obvious droplets will be left on the surface of the cutting saw blade 12. Therefore, when the cutting saw blade 12 rotates, the water will not be thrown onto the copper substrate. Moreover, when the sponge 31 contacts the cutting saw blade 12, it can also wipe the copper substrate cutting debris adhering to the surface of the cutting saw blade 12.

[0031] It should be noted that when the cutting saw blade 12 cuts the copper substrate, most of the debris will be adsorbed and collected by the vacuum cleaner at its bottom through the cutting opening 4.

[0032] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
