Description

Technical Field

[0001] This invention relates to a cutting machine mainly used for cutting plates such as ceramic substrates, and more particularly to a plate cutting machine and method that can simultaneously cut and test the strength of plates. Background Technology

[0002] Ceramic substrates are a type of circuit board. They are made from refined, high-purity inorganic materials, with their composition and uniformity precisely controlled through chemical or physical methods. They are then formed using methods such as dry pressing, slurry casting, or injection molding, followed by a sintering process and further processing to create the finished product. Unlike traditional FR-4 or aluminum substrates, ceramic substrates have a thermal expansion coefficient close to that of semiconductors and high heat resistance. They also possess properties such as hardness, wear resistance, pressure resistance, high heat resistance, acid resistance, and alkali resistance, making them suitable for products with high heat generation (e.g., high-brightness LED substrates, LED automotive lights, LED streetlights, solar inverters, etc.).

[0003] Before use, the substrate needs to be cut (cut) to a suitable size. In particular, for brittle and hard ceramic substrates, a pretreatment to form a cut line is required before cutting. Then, during subsequent processing, pressure is applied along the edge of the cut line to separate the board along the cut line. The cut line can be formed by scribing with a scribing wheel, laser ablation, etc.

[0004] In addition, in order to understand whether the strength of the substrate meets the requirements, it is currently necessary to conduct destructive testing on the substrate. However, since the board under test becomes a scrap board after destructive testing and must be scrapped, it results in cost waste. Therefore, destructive testing can only be carried out by sampling inspection and cannot achieve 100% inspection. Furthermore, since the machine used to test the strength is set up separately from the cutting machine, it occupies more space. Summary of the Invention

[0005] Based on the foregoing, the main objective of this invention is to provide a cutting machine and cutting method that can detect the strength of plates such as ceramic substrates while cutting them.

[0006] The present invention provides a plate cutting machine capable of simultaneously detecting the strength of plate components, comprising: a fixed platform for fixing the plate component; a lifting seat disposed above the fixed platform, with multiple cutting blocks arranged around the lower part of the lifting seat; multiple stress sensors respectively connected to the cutting blocks, and the stress sensors electrically connected to a computer unit; and a drive mechanism for driving the lifting seat or the fixed seat to rise or fall relative to each other in the vertical direction. The upper surface of the plate component has a pre-formed cutting line. When the lifting seat or the fixed platform is driven close to each other, the cutting blocks apply vertical pressure to the edge of the cutting line on the plate component, causing the portion of the plate component surrounding the cutting line to be cut off. Simultaneously, the stress experienced by the plate component at the time of cutting is transmitted to the stress sensors, converted into electronic values, and transmitted to the computer unit. This cutting machine allows for immediate strength detection of the plate component upon cutting, and the transmission of relevant data to the computer unit for processing and analysis. This enables the immediate rejection of defective products, significantly improving production efficiency and saving factory space occupied by testing equipment.

[0007] In another embodiment of the invention, the fixed platform can be fixedly set, and the drive mechanism is used to drive the lifting seat to rise or fall relative to the fixed platform.

[0008] In another embodiment of the invention, the lifting seat can be fixedly installed, and the drive mechanism is used to drive the fixed platform to rise or fall relative to the lifting seat.

[0009] In one embodiment of the invention, the lower ends of each of the cutting blocks are at the same height. When the lifting seat or the fixed platform is driven to approach each other, the cutting blocks simultaneously apply vertical pressure to each edge of the cutting line of the plate, so that the portion of the plate outside the cutting line is cut off and separated.

[0010] In another embodiment of the invention, the lower ends of each of the cut-off blocks can be at different heights. When the lifting seat or the fixed platform is driven to approach each other, the cut-off blocks apply vertical pressure to the plate sequentially along the edges of the rectangular cut-off line from the lowest to the highest of their lower ends, so that the portion of the plate outside the cut-off line is cut off and separated.

[0011] In a preferred embodiment of the present invention, the fixing platform is provided with a plurality of air holes, which are connected to a vacuum pump. When the vacuum pump is running, a negative pressure is formed in the air holes to adsorb the plate placed on the fixing platform. With this structure, the plate can be quickly fixed to the fixing platform by vacuum adsorption force, or the plate can be quickly removed from the fixing platform when the vacuum is released.

[0012] In a preferred embodiment of the present invention, the lifting seat may include: a pressing platform having four slots arranged on its four sides to form a rectangle and extending vertically; and a connecting seat connected to one side of the pressing platform, the connecting seat being connected to the driving mechanism. The stress sensors are disposed above the pressing platform, and the cutting blocks are disposed below the pressing platform. The stress sensors and the cutting blocks are respectively connected via connecting blocks, and the connecting blocks are respectively accommodated within the slots. Therefore, while the lower cutting blocks are cutting the plate, they can transmit the relevant stress to the upper stress sensors via the connecting seats, preventing the stress sensors from being damaged by external forces.

[0013] In one embodiment of the present invention, a pressure plate may be provided within the area surrounded by the cutting blocks below the pressure platform, and the lower surface of the pressure plate is positioned below the height of the lowest lower end face of the cutting blocks. Therefore, in this structure, before the cutting blocks descend to contact the plate, the pressure plate first presses down on the plate, and then the cutting blocks contact the plate and cut it off.

[0014] This invention provides a plate cutting method that can simultaneously detect the strength of a plate, comprising: forming a cutting line on the upper surface of the plate; and a plate cutting machine applying vertical downward pressure to the plate along the edge of the rectangular cutting line, so that the portion of the plate outside the cutting line is cut off and separated, and at the same time as the portion of the plate outside the cutting line is cut off and separated, the stress on the plate at the time of cutting is transmitted to a stress sensor, and converted into electronic values ​​and transmitted to a computer unit.

[0015] According to another embodiment of the cutting method of the present invention, the plate cutting machine may simultaneously apply vertical pressure to each edge of the plate, so that the portion of the plate outside the cutting line is cut off and separated; or the plate cutting machine may sequentially apply vertical downward pressure to the plate along each edge of the cutting line, so that the portion of the plate outside the cutting line is cut off and separated.

[0061] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and component symbols, so that those skilled in the art can implement them after studying this specification.

[0062] like Figures 1 to 7 As shown, the present invention provides a plate cutting machine 1 capable of simultaneously cutting and testing the strength of plates. One embodiment may have a fixed platform 11 and a drive mechanism 12 mounted on a base 10. A lifting seat 14 is connected to the drive mechanism 12, positioned above the fixed platform 11. The drive mechanism 12 drives the lifting seat 14 to rise or fall vertically. The fixed platform 11 has multiple air holes connected to a vacuum pump (not shown). When the vacuum pump operates, air is extracted from the air holes to create a negative pressure, thereby creating suction above the fixed platform 11. This allows the fixed platform 11 to adsorb and fix the plate 2 onto it (e.g., ...). Figure 5 (As shown).

[0063] like Figure 5 and Figure 7 As shown, the drive mechanism 12 is configured on the base 10 and a vertical plate 120 fixed to the base 10. The drive mechanism 12 includes a motor 121 disposed on one side of the vertical plate 120 and a screw 123 disposed on the other side of the vertical plate 120. The two ends of the screw 123 are vertically disposed by engaging bearing seats 1232 fixed above and below the vertical plate 120. A driven pulley 1231 is disposed at the upper end of the screw 123. The driven pulley 1231 is connected to the bearing seat 1232 fixed above and below the vertical plate 120. The main shaft's drive pulley 1211 is connected by a belt 122 to form a linkage relationship; the screw 123 is also helically fitted with a moving block 1233. Therefore, when the motor 121 operates and drives the drive pulley 1211 to rotate, the driven pulley 1231 and the screw 123 rotate via the belt 122. When the screw 123 rotates, it drives the moving block 1233 to move along the screw 123. That is, when the screw 123 is driven to rotate in the forward or reverse direction, it drives the moving block 1233 to rise or fall. In addition, two symmetrically arranged and vertically positioned rails 13 are provided on one side of the vertical plate 120 on which the screw 123 is arranged, and each rail 13 is slidably fitted with a slider 143.

[0064] The lifting seat 14 is connected to the drive mechanism 12 and is disposed above the fixed platform 11. The lifting seat 14 includes a pressing platform 141 and a connecting seat 142. The pressing platform 141 is horizontally disposed, and the connecting seat 142 is fixedly disposed on one side of the pressing platform 141 and is substantially perpendicular to the pressing platform 141. The pressing platform 141 has four slots 1411-1414 arranged on its four sides to form a rectangle and extending vertically through it, namely, a first slot 1411, a second slot 1412, a third slot 1413, and a fourth slot 1414. Four slots 1414; four stress sensors 16A~16D are arranged above the pressing platform 141, namely the first stress sensor 16A, the second stress sensor 16B, the third stress sensor 16C, and the fourth stress sensor 16D; four cutting blocks 18A~18D are arranged below the pressing platform 141, namely the first cutting block 18A, the second cutting block 18B, the third cutting block 18C, and the fourth cutting block 18D. The stress sensors 16A~16D are connected to the cutting blocks 18A~18D via connecting blocks 15A~15D. The stress sensors 16A~16D are electrically connected to a computer unit (not shown in the figure).

[0065] More specifically, the first connecting block 15A is accommodated within the first slot 1411. The first stress sensor 16A, located above the pressing platform 141, is secured to the top of the first connecting block 15A by a fixing element such as a screw, and the first cut-off block 18A is secured to the bottom of the first connecting block 15A by a fixing element such as a screw. Therefore, the first stress sensor 16A and the first cut-off block 18A are respectively fixed above and below the pressing platform 141. The second connecting block 15B is accommodated within the second slot 1412. The second stress sensor 16B, located above the pressing platform 141, is secured to the top of the second connecting block 15B by a fixing element such as a screw, and the second cut-off block 18B is secured to the bottom of the second connecting block 15B by a fixing element such as a screw. Therefore, the second stress sensor 16B and the second cut-off block 18B are respectively fixed above and below the pressing platform 141. The third connecting block 15C is housed in the third slot 1413. The third stress sensor 16C, located above the pressing platform 141, is secured to the top of the third connecting block 15C by a fixing element such as a screw. The third cut-off block 18C is secured to the bottom of the third connecting block 15C by a fixing element such as a screw. Thus, the third stress sensor 16C and the third cut-off block 18C are respectively fixed above and below the pressing platform 141. The fourth connecting block 15D is housed in the fourth slot 1414. The fourth stress sensor 16D, located above the pressing platform 141, is secured to the top of the fourth connecting block 15D by a fixing element such as a screw. The fourth cut-off block 18D is secured to the bottom of the fourth connecting block 15D by a fixing element such as a screw. Thus, the fourth stress sensor 16D and the fourth cut-off block 18D are respectively fixed above and below the pressing platform 141. After the stress sensors 16A-16D are installed on the pressing platform 141, they are covered and fixed by the fixing plate 17 to protect the stress sensors 16A-16D. Furthermore, preferably, a pressing plate 19 is provided within the area surrounded by the cut-off blocks 18A-18D below the pressing platform 141, and the lower surface of the pressing plate 19 is positioned below the height of the lowest lower end face of the cut-off blocks 18A-18D, that is, the lower end face of the pressing plate 19 is the lowest compared to the lower end face of the cut-off blocks 18A-18D.

[0066] The lifting seat 14 is connected to the drive mechanism 12 by fixing the connecting seat 142 to the moving block 1233 and the two sliders 143. Therefore, when the screw 123 is driven to rotate in the forward or reverse direction and causes the moving block 1233 to rise or fall, the lifting seat 14 will rise or fall at the same time.

[0067] In embodiments of the present invention, the lower ends of the four rectangular cut-off blocks 18A-18D are all at the same height. Alternatively, at least two of the four rectangular cut-off blocks 18A-18D have their lower ends at the same height, while the lower ends of the remaining two opposite cut-off blocks are at different heights and also at different heights from the lower ends of the aforementioned two cut-off blocks; for example, the lower ends of the first cut-off block 18A and the third cut-off block 18C are at the same height, and the lower ends of the second cut-off block 18B and the fourth cut-off block 18D are at different heights and also at different heights from the lower ends of the first cut-off block 18A and the third cut-off block 18C; the height of the lower ends of the four cut-off blocks 18A-18D can be achieved by making the cut-off blocks 18A-18D have the same or different thicknesses. Alternatively, the lower ends of the cut-off blocks 18A to 18D can be positioned at different heights; for example, the lower end of the first cut-off block 18A is the lowest, the lower end of the second cut-off block 18B is the second lowest, the lower end of the third cut-off block 18C is the third lowest, and the lower end of the fourth cut-off block 18D is the highest; the lower ends of the cut-off blocks 18A to 18D being positioned at different heights can be implemented by setting each of the cut-off blocks to have a different thickness.

[0068] The plate cutting machine 1 of this invention is mainly used to cut brittle and hard plates 2, such as ceramic substrates. Figure 5 , Figure 7 and Figure 8 As shown, before the plate 2 is cut, the area to be broken needs to be marked on the plate surface. For ceramic substrates, for example, a laser device can be used to apply a laser to the plate 2 to cut a rectangular cutting line 21 of appropriate depth. This cutting line 21 serves as the reference line for the plate's breakage and can also be called a "break line" or "crack". Generally, the inner dimension of the rectangle enclosed by the cutting line 21 corresponds to the outer dimension of the fixed platform 11. The plate 2, after the rectangular cutting line 21 has been pre-cut with a laser, is placed on the fixed platform 11, and a vacuum pump is started to continuously extract the air from the pores on the fixed platform 11. By creating negative pressure in the pores, the plate 2 is adsorbed and fixed on the fixed platform 11 (e.g., ...). Figure 7 (As shown).

[0069] Next, the motor 121 of the drive mechanism 12 is started, and the lifting seat 14 is lowered by the aforementioned drive method until the lower pressure plate 19 first presses and fixes the plate 2 further. Then, the continuously descending cutting blocks 18A~18D apply pressure along the edge of the cutting line 21 on the plate 2 to cut off and separate the plate 2 outside the cutting line 21 (e.g., Figure 8(As shown). Specifically, as previously described, when the lower ends of each of the cut-off blocks 18A to 18D are at the same height, the descending cut-off blocks 18A to 18D simultaneously apply vertical pressure along the edges of each cut-off line to cut the plate. When the lower ends of the first cut-off block 18A and the third cut-off block 18C are at the same and lower height, but the lower ends of the second cut-off block 18B and the fourth cut-off block 18D are at different heights and higher than the lower ends of the first and third cut-off blocks 18A and 18C, the lifting seat 14 descends until the lower pressure plate 19 first presses and fixes the plate 2 further. Then, the continuously descending first and third cut-off blocks 18A and 18C first apply pressure along the edges of the cut-off lines 21 on opposite sides of the plate 2. Then, the continuously descending second and fourth cut-off blocks 18B and 18D apply pressure along the edges of the cut-off lines 21 on the other opposite sides of the plate 2 to cut and separate the plate 2 outside the cut-off lines 21. Alternatively, when the lower ends of the first cutting blocks 18A to the fourth cutting blocks 18D are sequentially positioned from lowest to highest, the lifting seat 14 descends until the lower pressure plate 19 further presses and fixes the plate 2. Then, the continuously descending first to fourth cutting blocks 18A, 18B, 18C, and 18D sequentially apply pressure along the edges of the cutting line 21 on the plate 2 to cut off and separate the plate 2 outside the cutting line 21. During the process of applying pressure to the plate 2, the stress on each edge of the cutting line 21 is transmitted to the stress sensors 16A to 16D through the cutting blocks 18A to 18D and the connecting blocks 15A to 15D. When the plate 2 is cut off, the stress sensors 16A to 16D detect the maximum stress value and convert the obtained stress value into an electronic value, which is then transmitted to the computer unit. Therefore, the effect of cutting off and inspecting each plate 2 100% without omission is achieved.

[0070] The aforementioned cut-off line formed on the plate is not limited to a rectangle. It can be formed into a circle, polygon, or other geometric shape according to the actual needs of the product. In this case, the arrangement of the plurality of cut-off blocks must also be arranged according to the shape of the cut-off line so that the cut-off blocks can apply vertical pressure to the edge of the cut-off line to cut it off.

[0071] In another embodiment of the present invention (not shown in the figure), the lifting seat can be set as fixed, and the drive mechanism can be connected to the fixed platform to drive the fixed platform to rise or fall. The same effect can be achieved by using the cutting block to cut the plate when the lifting seat and the fixed platform are close to each other.

[0072] Using the aforementioned plate cutting machine, the plate cutting method provided by the present invention, which can simultaneously detect the strength of a plate, includes: forming a cutting line on the upper surface of a plate; and applying vertical pressure to the plate along the edge of the cutting line using the plate cutting machine, so that the portion of the plate outside the cutting line is cut off and separated.

[0073] The above description is merely for explaining preferred embodiments of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications or alterations made to the present invention under the same inventive spirit should still be included within the scope of protection intended by the present invention.
