Description

Technical Field

[0001] This case mainly relates to a cutting machine for cutting plate materials such as ceramic substrates, and particularly relates to a plate material cutting machine and a method thereof capable of simultaneously performing plate material cutting and strength detection.

Background Art

[0002] A ceramic substrate is a type of circuit board. It uses highly purified inorganic materials as raw materials, precisely controls the composition and uniformity through chemical or physical means, and then, after being formed by dry pressing, paste casting, injection molding, etc., it is continuously processed into a product through a sintering step. Different from conventional FR-4 and aluminum substrates, it has a thermal expansion coefficient close to that of a semiconductor and high heat resistance, and also has characteristics such as hardness, wear resistance, pressure resistance, high heat resistance, acid resistance, and alkali resistance, making it suitable for products with a large amount of heat generation (such as high-brightness LED carrier substrates, automotive LED lighting lamps, LED street lamps, solar inverters, etc.).

[0003] Before use, the substrate needs to be cut (trimmed) to an appropriate size. Especially before cutting a brittle and hard ceramic substrate, after undergoing a pretreatment of forming a cutting line, in the subsequent processing process, pressure is applied along the edge so that the plate material is separated along the cutting line. The cutting line can be formed, for example, by using a cutting wheel (forming a cutting line), or by methods such as laser ablation.

[0004] Also, in order to know whether the strength of the substrate meets the regulations, a destructive test of the plate material is required. Therefore, the plate material after the destructive test becomes waste material and has to be discarded, which may result in a waste of costs. Thus, the destructive test is only a sampling test and cannot perform a 100% test. Furthermore, since the machine used for the strength test is installed separately from the cutting machine, it takes up a lot of space.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, the main object of the present invention is to provide a sheet material cutting machine and a method thereof capable of simultaneously performing sheet material cutting and strength detection.

Means for Solving the Problems

[0006] The sheet material cutting machine capable of simultaneously performing sheet material cutting and strength detection provided in the present invention includes a fixed table for fixing a sheet material, a plurality of cutting blocks arranged around the lower part, a lifting table arranged above the fixed table, a plurality of stress sensors respectively connected to the plurality of cutting blocks and connected to a computer device, and a driving mechanism for driving the lifting table or the fixed table to move up and down in a direction perpendicular to each other. The upper surface of the sheet material forms a cutting line in advance. When the lifting table or the fixed table is driven to approach each other, the plurality of cutting blocks apply a vertical pressure to the edge of the cutting line of the sheet material, thereby cutting and separating the edge of the cutting line of the sheet material. At the same time, the stress received by the sheet material during cutting is transmitted to each stress sensor, replaced by an electronic signal, and transmitted to the computer device. By applying the cutting machine of the present invention, when the sheet material is cut, the strength of the sheet material can be quickly detected, and the relevant data is transmitted to the computer device for processing and analysis. Therefore, defective products can be immediately excluded, the production efficiency can be greatly improved, and the space occupied by the inspection device in the factory can be saved.

[0007] In another embodiment of the present invention, for example, the fixed table can be fixedly installed, and the driving mechanism can be used to drive the lifting table up and down with respect to the fixed table.

[0008] In another embodiment of the present invention, for example, the lifting table can be fixedly installed, and the driving mechanism can be used to drive the fixed table up and down with respect to the lifting table. In one embodiment of the present invention, the lower ends of each of the cutting blocks are located at the same height. When the lifting table or the fixed table is driven to approach each other, at the same time, those cutting blocks apply a vertical pressure to the edges of each cutting line of the sheet material, and the peripheral part of the cutting line of the sheet material is cut and separated.

[0009] In another embodiment of this case, the lower ends of these cutting blocks may be provided at different heights from each other. When the lifting platform or the fixed table is driven close to each other, these cutting blocks apply pressure perpendicular to the plate material in sequence from the one with the lowest lower end to the one with the highest lower end along the edge of the rectangular cutting line, cutting and separating the edge of the cutting line of the plate material.

[0010] In a preferred embodiment of this case, a plurality of air holes are provided in the fixed table. These air holes are connected to a vacuum pump, and the vacuum pump is operated to form a negative pressure in the air holes, and the plate material placed on the fixed table is adsorbed. With such a structure, the plate material can be quickly fixed to the fixed table by the vacuum adsorption force, or the vacuum can be released to quickly remove the plate material from the fixed table.

[0011] In a preferred embodiment of this case, a lifting platform including a placement table with four sides forming a rectangle and provided with four through holes penetrating up and down, and a connection table connected to the driving mechanism and connected to one side of the placement table, for example, a stress sensor is arranged above the placement table, the cutting block is arranged below the placement table, the stress sensor and the cutting block are respectively connected through a connecting block, and the connecting block can be respectively housed in the through hole. With this configuration, while the lower cutting block cuts the plate material, the stress sensor transfers the connecting block to the upper stress sensor respectively, and the stress sensor avoids damage caused by external force.

[0012] In an embodiment of this case, for example, a pressing plate may be provided in the range surrounded by the cutting block below the placement table, and the position of the lower surface of the pressing plate can be set lower than the height position of the lowest lower end surface of the cutting block. With this structure, when the cutting block descends and contacts the plate material, first, the plate material is pressed by the pressing plate, and then the cutting block contacts the plate material and the plate material is cut.

[0013] In this case, there is further provided a cutting method capable of simultaneously detecting the strength of a plate material, including the steps of forming a cutting line on the upper surface of the plate material, and applying a downward vertical pressure to the plate material along the edge of the rectangular cutting line by using the plate material cutting machine according to any one of claims 1 to 8 to cut and separate the edge of the cutting line provided on the plate material; and simultaneously transmitting the stress received by the plate material during cutting to a stress sensor when the edge of the cutting line is cut, replacing it with an electronic signal, and transmitting it to a computer device.

[0014] In another embodiment of the cutting method of this case, for example, when the plate material cutting machine applies a vertical pressure to the edge of the plate material, it can cut and separate the edge of the cutting line of the plate material, or the plate material cutting machine can sequentially apply a vertically downward pressure along the edge of the cutting line of the plate material for cutting and separation.

Embodiments for Carrying out the Invention

[0016] In order for those skilled in the art to be able to implement the present invention as appropriate, the following will describe the embodiments of the present case in more detail in conjunction with the accompanying drawings and the reference numerals of the components.

Example

[0017] As shown in FIGS. 1-7, an embodiment of a sheet cutting machine 1 capable of simultaneously performing sheet cutting and strength detection of the present case includes a fixed table 11 and a drive mechanism 12 on a base 10. A lifting platform 14 is connected to the drive mechanism 12, and the lifting platform 14 corresponds to the upper part of the fixed table 11. The drive mechanism 12 is used to drive the lifting platform 14 to rise or fall in the vertical direction. Among them, a plurality of air holes are provided in the fixed table 11, and these air holes are connected to a vacuum pump (not shown). When operating, the air in the air holes is extracted by the vacuum pump to form a negative pressure, and a suction force is formed above the fixed table 11, forming a configuration suitable for adsorbing and fixing the sheet material 2 to the fixed table 11 (see FIG. 5).

[0018] As shown in FIGS. 5 and 7, the drive mechanism 12 is arranged with a vertical plate 120 fixed to the base 10 perpendicular to the base 10. The drive mechanism 12 includes a motor 121 provided on one side of the vertical plate 120 and a screw 123 provided on the other side of the vertical plate 120. Both ends of the screw 123 are vertically arranged together with bearing blocks 1232 fixed at the upper and lower positions of the vertical plate 120. A passive pulley 1231 is provided at the upper end of the screw 123. The passive pulley 1231 and the main pulley 1211 provided on the main shaft of the motor 121 are combined, and the passive pulley 1231 and the screw 123 are driven to rotate by a belt 122. When the screw 123 rotates, the sliding block 1233 is driven to move along the screw 123. That is, when the screw 123 is rotationally driven in the forward or reverse direction, the sliding block 1233 is driven to rise or fall. Further, on one side surface of the vertical plate 120 arranged on the screw 123, the left and right are opposed, and two rails 13 are arranged in the vertical direction. Each rail 13 is slidably arranged on a slider 143 respectively.

[0019] The lifting platform 14 is connected to the drive mechanism 12 and is arranged above the fixed table 11. The lifting platform 14 includes a placement table 141 and a connection base 142. The placement table 141 is arranged horizontally, and the connection base 142 is fixedly installed offset above the placement table 141 and, in principle, maintains a perpendicular relationship with the placement table 141. The placement table 141 has four sides forming a rectangle and is penetrated vertically. Four grooves 1411 - 1414, namely the first groove hole 1411, the second groove hole 1412, the third groove hole 1413, and the fourth groove hole 1414, are arranged. Above the placement table 141, four stress sensors 16A - 16D, namely the first stress sensor 16A, the second stress sensor 16B, the third stress sensor 16C, and the fourth stress sensor 16D, are respectively provided. Below the placement table 141, four cutting blocks 18A - 18D, namely the first cutting block 18A, the second cutting block 18B, the third cutting block 18C, and the fourth cutting block 18D, are respectively provided. Those stress sensors 16A - 16D are respectively connected to those cutting blocks 18A - 18D by connection blocks 15A - 15D. Those stress sensors 16A - 16D are electrically connected to a computer device (not shown).

[0020] More specifically, the first connection block 15A is received in the first groove 1411, and the first stress sensor 16A located above the placement table 141 is fixed to the upper part of the first connector 15A by a fixing element such as a screw. The first cutting block 18A is fixed to the lower part of the first connector 15A by a fixing element such as a screw. Therefore, the first stress sensor 16A and the first cutting block 18A are fixed above and below the placement table 141 respectively. The second connection block 15B is received in the second groove 1412, and the second stress sensor 16B located above the placement table 141 is fixed to the upper part of the second connector 15B by a fixing element such as a screw. The second cutting block 18B is fixed to the lower part of the second connector 15B by a fixing element such as a screw. With this configuration, the second stress sensor 16B and the second cutting block 18B are fixed above and below the placement table 141 respectively. The third connector 15C is received in the third groove 1413, and the third stress sensor 16C located above the placement table 141 is fixed to the upper part of the third connector 15C by a fixing element such as a screw. The third cutting block 18C is fixed to the upper part of the third connector 15C by a fixing element such as a screw. Thus, the third stress sensor 16C and the third cutting block 18C are fastened to the lower surface of the third connector 15C so as to be fixed above and below the placement table 141 respectively. The fourth connector block 15D is received in the fourth groove 1414, and the fourth stress sensor 16D arranged above the placement table 141 is fastened to the lower surface of the fourth connector 15D by a fixing element such as a screw. The fourth cutting block 18D is fastened to the lower side of the fourth connector 15D by a fixing element such as a screw. As a result, the fourth stress sensor 16D and the fourth cutting block 18D are fixed above and below the placement table 141 respectively. After the stress sensors 16A - 16D are arranged on the placement table 141, they are covered and fixed by the fixing plate 17, and a protective function is formed for the stress sensors 16A - 16D.Furthermore, preferably, for example, a pressing plate 19 is provided within a range surrounded by the cutting blocks 18A to 18D below the placement table 141. The position of the lower surface of the pressing plate 19 is located at the height of the lowest lower end surface of the cutting blocks 18A to 18D. That is, when compared with the lower ends of the cutting blocks 18A to 18, the lower end of the pressing plate 19 is at the lowest position.

[0021] The lifting platform 14 is connected to the drive mechanism 12 by fixing the connection platform 142 to the sliding block 1233 of the drive mechanism 12 and two sliders 142. By driving the screw 123 to rotate forward and backward to raise or lower the sliding block 1233, the lifting platform 14 is also driven to rise or fall simultaneously.

[0022] In the embodiment of the present invention, for example, the lower ends of the four cutting blocks 18A to 18D surrounding the rectangular body may be at the same height position. Alternatively, among the four cutting blocks 18A to 18D arranged in a rectangle, at least two opposite lower ends are at the same height position, the lower ends of the remaining two cutting blocks are at different positions from each other, and at a height position different from the lower ends of the aforementioned two cutting blocks. For example, the lower end of the first cutting block 18A and the lower end of the third cutting block 18C are at the same height position, the lower end of the second cutting block 18B and the lower end of the fourth cutting block 18D are at different height positions. The height positions of the lower ends of the four cutting blocks 18A to 18D can be implemented to have the same thickness or different thicknesses as the cutting blocks 18A to 18D. Or, it is also possible to set the lower ends of the cutting blocks 18A to 18D at different height positions. For example, setting the lower end of the first cutting block 18A to be the lowest, the lower end of the second cutting block 18B to be the second lowest, the lower end of the third cutting block 18C to be the third lowest, and the lower end of the fourth cutting block 18D to be the highest. Setting the lower ends of the cutting blocks 18A to 18D at different height positions can be implemented by setting the cutting blocks 18A to 18D at different height positions.

[0023] The sheet cutting machine 1 of this case is mainly used for cutting brittle and hard sheets 2 such as ceramic substrates. As shown in FIGS. 5, 7, and 8, before cutting the sheet 2, it is first necessary to draw the cutting range on the surface of the sheet. For example, in the case of a ceramic substrate, a laser is applied to the sheet 2 using a laser device, and a rectangular cutting line 21 with an appropriate depth serving as the base point of the disconnection line of the sheet is engraved. This cutting line 21 can be called a "breaking line" or a "crack". Generally, the inner dimensions of the rectangle surrounded by such a cutting line 21 correspond to the outer dimensions of the fixed table 11. After the rectangular cutting line 21 is cut off by the laser light in advance, the sheet 2 is attached onto the fixed table 11, the vacuum pump is operated, and the air in the air holes of the fixed table 11 is continuously extracted to form a negative pressure in the air holes 11, thereby adsorbing and fixing the sheet 2 to the fixed table 11 (see FIG. 7).

[0024] Subsequently, the motor 121 of the drive mechanism 12 is activated, and the lifting platform 14 is lowered by the above-described driving method until the pressing plate 19 further presses and fixes the plate material 2. Then, the cutting blocks 18A - 18D that continue to descend press the plate material 2 other than the cutting line 21 on the plate material 2 along the edge of the cutting line 21 on the plate material 2, thereby cutting and separating it (see Fig. 8). Specifically, as described above, when the lower ends of the cutting blocks 18A - 18D are at the same height position, the descending cutting blocks 18A - 18D apply a vertical pressure simultaneously along the edge of the cutting line 21 to cut the plate material 2. The lower ends of the first cutting block 18A and the third cutting block 18C are also at the same low height position, but the lower ends of the second cutting block 18B and the fourth cutting block 18D are at different height positions, and when they are at a position higher than the height position of the lower ends of the first cutting block 18A and the third cutting block 18C, the lifting platform 14 descends until the pressing plate 19 further presses and fixes the plate material 2. Then, the continuously descending first and third cutting blocks 18A and 18D first apply a pressing force along the edge of the cutting line 21 on the opposite side of the plate material 2, and then the continuously descending second and fourth cutting blocks 18B and 18D apply a pressing force along the edge of the cutting line 21 on the other opposite side of the plate material 2 to cut the part of the plate material 2 other than the cutting line 21. Or, when the height positions of the lower ends of the first cutting block 18A - the fourth cutting block 18D increase in order from the lowest, the lifting platform 14 is lowered by the pressing plate 19 until the plate material 2 is further pressed and fixed, and then the continuously descending first cutting block 18A - the fourth cutting block 18B, 18C, 18D sequentially apply a pressing force along the respective edges of the cutting line 21 of the plate material 2 to cut and separate the plate material 2 other than the cutting line 21. In the process of applying pressure to the plate material 2, the stress received on both sides of the cutting line 21 is transmitted to the stress sensors 16A - 16D through the cutting blocks 18A - 18D and the connection blocks 15A - 15D respectively. When the plate material 2 is cut, the maximum value of the stress detected by the stress sensors 16A - 16D is replaced by an electronic signal and transmitted to the computer device, so that the plate material 2 can achieve the effect of being 100% detected simultaneously with cutting without being overlooked.

[0025] Note that the cutting line formed on the plate material 2 is not limited to a rectangle, and it can also be formed into a geometric shape such as a circle or a polygon according to the needs of the actual product. In that case, a plurality of cutting blocks can be configured according to the shape of the cutting line, and a vertical pressure can be applied to the edge of the cutting line to enable cutting.

[0026] In another embodiment of the present invention (not shown in the drawings), the lifting platform 14 can also be fixed, and the driving mechanism 12 can be used to drive the fixed table 11 to rise or fall. Similarly, when the lifting platform 14 and the fixed table 11 are close to each other, the effect of cutting the plate material 2 using the cutting block can be achieved.

[0027] When the plate material cutting machine 1 of the present invention is applied, a plate material cutting method capable of simultaneously detecting the strength of the plate material includes a step of forming a cutting line on the upper surface of the plate material 2, and a step of cutting and separating the edge of the cutting line of the plate material 2 by applying a vertical pressure to the plate material 1 along the edge of the cutting line using the plate material cutting machine 1.
