Description

Technical Field

[0001] This invention relates to a method for feeding a material to be cut and a cutting device, and more particularly to a method for feeding a ceramic substrate onto a stage for cutting in the process of electronic components. Background Technology

[0002] It is known that in the manufacturing process of passive components, there is often a need to cut materials such as ceramic substrates. Patent No. CN1260049C, "Cut Machine for Multilayer Ceramic Capacitors and Inductors," discloses a cutting device consisting of a control system, a stage, a camera device, and a cutting mechanism. The stage is used to place the ceramic substrate (plate) and is controlled by the control system to move horizontally forward and backward and rotate. The camera device is aimed at the upper surface of the stage and can provide the control system with the orientation information of the silkscreen lines on the ceramic substrate. The cutting mechanism is located above the stage and can be controlled by the control system to move vertically up and down to cut the ceramic substrate on the stage. When the cutting device is cutting, the control system controls the forward and backward movement or rotation of the stage according to the orientation information of the silkscreen lines on the ceramic substrate to adjust the alignment of the silkscreen lines with the cutting mechanism.

[0003] Patent No. I327951, "Loading and Unloading Mechanism and General Kit of Passive Component Cutting Machine," discloses another cutting device, which is provided with a loading arm and an unloading arm, and defines a loading area and an unloading area on both sides of the cutting area; the loading suction cup of the loading arm can move between the loading area and the cutting area to move the uncut ceramic substrate stored in the loading area into the cutting area for cutting; the unloading suction cup of the unloading arm can move between the cutting area and the unloading area to remove the cut ceramic substrate and store it in the unloading area.

[0004] In practice, uncut ceramic substrates stored in the loading area may be misaligned, causing them to be placed at an angle on the platform when moved to the cutting area. This results in a significant amount of time being spent adjusting the silkscreen lines to align with the cutting mechanism. If the misalignment is more severe than expected (e.g., too far to the left, right, or beyond the preset angle), the platform's displacement alone is insufficient to align the silkscreen lines with the cutting mechanism. When the control system determines that the misalignment of the ceramic substrate on the platform is more severe than expected, it will stop the cutting equipment and issue an alarm to notify the operator to resolve the issue. All of these drawbacks contribute to poor cutting efficiency. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a method for feeding cut materials that can overcome at least one drawback of the prior art.

[0006] Another object of the present invention is to provide a cutting device for performing the feeding method for the object to be cut as described above.

[0007] Another object of the present invention is to provide a cutting device that overcomes at least one disadvantage of the prior art.

[0008] The method for feeding a cut object according to the present invention includes: establishing preset orientation information of the cut object when it is cut on a platform; obtaining actual orientation information of the cut object before it is transferred to the platform; calculating the deviation value between the actual orientation information and the preset orientation information using a control unit; and adjusting the orientation of the cut object or the orientation of the platform according to the deviation value before the cut object is transferred to the platform, so that the cut object is placed on the platform in accordance with the preset orientation information.

[0009] A cutting apparatus according to another object of the present invention is used to perform the feeding method for the object to be cut as described.

[0010] According to another objective of the present invention, a cutting device includes: a loading and unloading device having a loading mechanism for transferring the object to be cut to a platform of a platform device; a cutting device disposed on one side of the loading and unloading device for cutting the object on the platform; a feed imager for taking an image of the object to be cut before it is transferred to the platform; and a control unit for adjusting the orientation of the object to be cut or the orientation of the platform based on the image taking result.

[0011] In the material feeding method and cutting device of this invention, before the material to be cut is transferred to the platform by the loading mechanism, the material to be cut is imaged by the feeding imager. The control unit can adjust the orientation of the transferred material to be cut or the orientation of the platform according to the image acquisition result, thereby enabling the material to be cut to be oriented during the transfer, so as to improve the efficiency of the cutting operation.

[0119] Please see Figure 1 The cut object W in this embodiment of the invention can be illustrated by taking a thin ceramic substrate used for manufacturing passive components as an example. The cut object W is rectangular and has multiple cut lines W1 on its side surface.

[0120] Please see Figure 2 The feeding method for the object to be cut in this embodiment of the invention can be described using the cutting equipment shown in the figure as an example, which includes:

[0121] A machine body A has a platform A1 and a frame A2;

[0122] A platform device B is disposed on the platform A1;

[0123] A feeding device C is located on the table A1, on one side (the left side of the platform device B).

[0124] A receiving device D is disposed on the platform A1, located on the other side of the platform device B opposite to the feeding device C (the right side of the platform device B).

[0125] A preheating device E is installed on the table A1, located on one side (behind the feeding device C) of the feeding device C.

[0126] An unloading device F is mounted on the frame A2 and suspended above the platform device B, the feeding device C, and the receiving device D.

[0127] A cutting device G is disposed on the table A1, located on one side (the rear side of the loading and unloading device F).

[0128] A control unit H can control the platform device B, the feeding device C, the receiving device D, the preheating device E, the loading and unloading device F, and the cutting device G to perform preset operations.

[0129] Please see Figure 2 , 3 The platform device B has a roughly rectangular platform B1 for placing the object to be cut W. The platform B1 has a placement surface B11 on its upper surface and four L-shaped marks B12 at its four corners. The marks B12 enclose a placement area B111 corresponding to the outer edge shape of the object to be cut W. The placement surface B11 has a plurality of suction holes B13 in the placement area B111. The object to be cut W can be adsorbed and held on the placement surface B11 by the negative pressure suction of the suction holes B13. The platform B1 has a plurality of heaters B14 to heat the object to be cut W held on the placement surface B11.

[0130] The platform device B has a Y-axis oriented rail seat B2 on the platform A1. One end of the rail seat B2 extends through the feeding device C and the receiving device D to one side of the machine body A (the front side of the machine body A), and the other end extends through the loading / unloading device F and the cutting device G to the other side of the machine body A (the rear side of the machine body A). The rail seat B2 has a platform driver B21, such as a linear motor, which can drive a moving seat B3 to perform horizontal displacement along the Y-axis. The moving seat B3 has a rotary motor, such as a direct drive motor. The rotating base B4 has a platform B1 mounted on it and driven to rotate horizontally relative to the movable base B3 with the Z-axis as the rotation center. The platform B1 can be controlled to rotate at different angles starting from an initial orientation. After rotation, the platform B1 will return to the initial orientation to await subsequent operations. The initial orientation is that the four longer outer edges of the platform B1 can be perpendicular or parallel to the X-axis. The platform B1 can be horizontally displaced along the Y-axis between the front and rear sides of the machine body A by the linkage of the movable base B3.

[0131] Please see Figure 4 , 5 The feeding device C is equipped with a material rack C1, a feeding and image taking mechanism C2 and a lifting mechanism C3;

[0132] The material rack C1 is equipped with a material seat C12 that can be dragged along a slide rail C11 in the Y-axis direction, and is equipped with a handle C13 for hand-held dragging; the material seat C12 has a hollow material seat opening C121 in the Z-axis direction, and multiple limiting members C122 are erected around the material seat opening C121; the material seat C12 is equipped with a lifting plate C14, which has multiple clearance openings C141 corresponding to the limiting members C122, and the limiting members C122 can pass through the clearance openings C141 and form an area on the lifting plate C14 for storing the object to be cut W; the material seat C12 is supported by two erected support members C123 for two rollers C124.

[0133] The feeding and imaging mechanism C2 is located relative to the stage device B of the feeding device C. Figure 2 On the other side, the feeding and imaging mechanism C2 is provided with a feeding imager C21, such as a CCD camera, and a bracket C22. The feeding imager C21 is supported by the bracket C22 at a height higher than the material rack C1. The feeding imager C21 captures images vertically from top to bottom.

[0134] The lifting mechanism C3 is located below the material rack C1. It has a lifting seat C31, a lifting rod C32 and a drive rod C33. The lifting seat C31 is fixed to one end of the lifting rod C32. The other end of the lifting rod C32 is connected to the drive rod C33 by a connector C34. The drive rod C33 can be driven by a driver C35 to drive the lifting rod C32 and the lifting seat C31 to perform vertical displacement in the Z-axis. When the lifting seat C31 is performing vertical displacement, the lifting seat C31 can pass through the material seat opening C121 of the material seat C12 and drive the lifting plate C14 to perform vertical displacement together.

[0135] Please see Figure 2 , 4 The structure of the receiving device D is roughly the same as that of the feeding device C, except that the receiving device D does not have an image acquisition mechanism. The structure of the receiving device D will not be described in detail here.

[0136] Please see Figure 5 , 6 7. The preheating device E is equipped with a heating mechanism E1 and a translation mechanism E2;

[0137] The heating mechanism E1 includes an image-capturing platform E11, one side of which is fixed to a frame E12, while the other side is unsupported, allowing the image-capturing platform E11 to be suspended below. The image-capturing platform E11 has a heating surface E111 on its upper surface, and the heating surface E111 has multiple suction holes E112. The object to be cut W can be adsorbed and held on the heating surface E111 by the negative pressure suction of the suction holes E112. The image-capturing platform E11 has multiple heaters E113 to heat the object to be cut W held on the heating surface E111.

[0138] The translation mechanism E2 is equipped with a driver E21, which drives the frame E12 to move the image-acquiring platform E11 horizontally along the Y-axis. This allows the image-acquiring platform E11 to selectively move to or away from the image-acquiring position of the feed image-acquiring device C21, selectively moving into or out of the area below the feed image-acquiring device C21 and above the limiting member C122 of the material rack C1. When the image-acquiring platform E11 moves between the feed image-acquiring device C21 and the material rack C1, the sides of the image-acquiring platform E11... The lower surface of component E114 is supported by the roller C124. The central axis of the feed imager C21 is offset from the central axis of the image platform E11 by a distance, so that the feed imager C21 can capture an image of the upper surface of the object to be cut W held on the image platform E11 within a field of view C211. The field of view C211 can simultaneously capture the entire outline of a first side W2 of the object to be cut, a partial outline of a second side W3 adjacent to the first side W2, and a partial outline of a third side W4 adjacent to the first side W2.

[0139] Please see Figure 2 , 8 The loading and unloading device F is equipped with a crossbeam F1, a loading mechanism F2 and an unloading mechanism F3;

[0140] The crossbeam F1 is arranged along the X-axis and fixed to the frame A2 at its rear. Two guide rods F11, spaced apart vertically along the X-axis, are provided on the front side of the crossbeam F1 for sliding a first slide block F12 and a second slide block F13. A first drive mechanism F14 and a second drive mechanism F15 are provided between the two guide rods F11. The first drive mechanism F14 can drive the first slide block F12 to stop at multiple points between the displacement start point and the displacement end point, and the second drive mechanism F15 can drive the second slide block F13 to stop only at the displacement start point or the displacement end point. In this embodiment of the invention, the first drive mechanism F14 can, for example, be a first driver F141 of a motor driving a screw F142 to move the first slide block F12, and the second drive mechanism F15 can, for example, be a second driver F151 of a cylinder driving the second slide block F13.

[0141] The loading mechanism F2 is mounted on the first slide F12 and is driven to perform horizontal displacement along the X-axis above the feeding device C and the platform device B. The loading mechanism F2 includes a third driver F21 (e.g., a cylinder) and a fourth driver F22 (e.g., a cylinder). The third driver F21 is fixed to the first slide F12 and can drive a mounting base F23 to perform vertical displacement along the Z-axis. The fourth driver F22 is fixed to the mounting base F23 and can drive a loading base F24 to perform vertical displacement along the Z-axis. The loading base F24 can be driven by the third driver F21 and the fourth driver F22 to perform two stages of vertical displacement. The fourth driver F22 can independently drive the loading base F24 to perform the first stage of vertical displacement, allowing the lower surface of the loading base F24 to approach the image acquisition platform E11. Figure 5 The upper surface of the rack; the third driver F21 and the fourth driver F22 can simultaneously drive the mounting base F23 and the loading base F24 to perform a second-stage vertical displacement, so that the loading base F24 can extend into the rack C1. Figure 5 The limiting member C122 () Figure 5 Between; the lower surface of the loading seat F24 is provided with a plurality of flexible suction nozzles F25, and the object to be cut W can be adsorbed and held on the lower surface of the loading seat F24 by the negative pressure suction of the suction nozzles F25; the loading seat F24 is provided with a plurality of heaters F241 to heat the object to be cut W held on the loading seat F;

[0142] The unloading mechanism F3 is mounted on the second slide F13 and is driven to make horizontal displacement in the X-axis above the platform device B and the receiving device D; the unloading mechanism F3 is provided with a fifth driver F31, such as a cylinder, which can drive an unloading seat F32 to make vertical displacement in the Z-axis. The lower surface of the unloading seat F32 is provided with a plurality of suction nozzles F33, and the object to be cut W can be adsorbed and held on the lower surface of the unloading seat F32 by the negative pressure suction of the suction nozzles F33.

[0143] Please see Figure 2 , 8 The cutting device G includes a frame G1, a feeding mechanism G2, a cutting mechanism G3, and a cutting image acquisition mechanism G4.

[0144] The frame G1 is set on the platform A1 in a gantry shape consisting of two pillars G11 and a crossbeam G12. Two slide rails G13 along the Z-axis are provided on the front side of the crossbeam G12.

[0145] The feeding mechanism G2 has a slide G21 on the slide rail G13, and a cutting driver G22, such as a motor, drives a driving rod G23 to move the slide G21 vertically in the Z-axis direction.

[0146] The cutting mechanism G3 is mounted on the slide G21 and can be driven by the slide G21 to make vertical displacement along the Z-axis, so that all the cutting blades G31 of the cutting mechanism G3 can perform straight cutting operations.

[0147] The cutting and imaging mechanism G4 is provided with two cutting and imaging devices G41, such as those of a CCD camera, on both sides of the cutting mechanism G3. The cutting and imaging devices G41 are tilted to capture images.

[0148] In the implementation of the object feeding method and cutting device of this invention, a preset orientation information M of the object W being cut on the platform B1 can be established first. Figure 10 This serves as a reference for adjusting the orientation of the workpiece W when it is fed into the machine. The operator can first place the workpiece W in the correct position on the platform B1, aligning it with the placement area B111 of the platform B1 and ensuring that the four corners of the workpiece W correspond to the mark B12. The central axis of the workpiece W should be coaxial with the central axis of the platform B1. Then, the suction nozzle F25 below the loading seat F24 of the loading mechanism F2 picks up the workpiece W from the platform B1 and transfers it to the image-taking and positioning position of the feed imager C21. The object is held in place by negative pressure adsorption on the imaging platform E11; then the feed imager C21 can capture an image of the upper surface of the object W to be cut on the imaging platform E11, capturing the outline and orientation of the first side W2, the second side W3 and the third side W3, and the control unit H calculates the preset orientation information M by an algorithm; wherein, the preset orientation information M has a preset center M1 and four preset sides M2; the algorithm can, for example, assume that the object W to be cut is a square, and calculate the center and the fourth side of the square given the three sides of the square;

[0149] Next, obtain the actual orientation information N of the object to be cut W before it is transferred to the platform B1. Figure 11Before being cut, the workpiece W is stored in the feeding device C. The loading mechanism F2 can be horizontally moved above the feeding device C, and the loading seat F24 is moved downward between the limiting members C122 so that the suction nozzle F25 can pick up the workpiece W in the feeding device C. After the suction nozzle F25 picks up the workpiece W in the feeding device C, the loading seat F24 is moved upward to a height higher than the heating mechanism E1 of the preheating device E, and the imaging platform E11 of the heating mechanism E1 is driven to move to a position below the workpiece W picked up by the suction nozzle F25 and above the limiting member C122, and the loading seat F24 is moved downward to pick up the workpiece W. The workpiece W is placed on the imaging platform E11, and is held by negative pressure on the heating surface E111 of the imaging platform E11 for heating. During the heating of the workpiece W on the imaging platform E11, the loading seat F24 moves upward and to one side (to the right), so that the feeding imager C21 can capture the upper surface of the workpiece W in the heated state on the imaging platform E11 from top to bottom, capturing the outline and orientation of the first side W2, the second side W3 and the third side W3, and the actual orientation information N is calculated by the control unit H through the algorithm. The actual orientation information N has an actual center N1 and four actual sides N2.

[0150] After obtaining the actual orientation information N, the control unit H calculates the deviation value between the actual orientation information N and the preset orientation information M. In this embodiment of the invention, the deviation value is calculated by the control unit H as the difference in horizontal distance between the actual center N1 and the preset center M1 in the X-axis and Y-axis directions (e.g., Figure 11 ), or the difference in horizontal angle between the actual center N1 and the preset center M1 after they are coaxial (e.g. Figure 12 );

[0151] After the control unit H calculates the deviation value, before the object to be cut W is transferred to the platform B1 by the loading mechanism F2, the orientation of the object to be cut W or the orientation of the platform B1 is adjusted according to the deviation value, so that the object to be cut W is transferred to the platform B1 in accordance with the preset orientation information M; during the transfer of the object to be cut W by the loading mechanism F2, the loading seat F24 is moved again to above the object to be cut on the image acquisition platform E11, so that the loading seat F24 moves downward so that the suction nozzle F25 can pick up the object to be cut on the image acquisition platform E11, and then the loading seat F24 moves upward to move the object to be cut out of the image acquisition platform E11 and move towards the platform device B, by means of the control unit H. The loading mechanism F2 is controlled by element H to perform horizontal displacement along the X-axis, and the platform B1 is controlled to perform horizontal displacement along the Y-axis, so that the actual center N1 of the actual orientation information N first aligns with the preset center M1 of the preset orientation information M. Then, the platform B1 is controlled to perform horizontal rotational displacement, so that the actual edge N2 of the actual orientation information N aligns with the preset edge M2 of the preset orientation information M. When the actual orientation information N and the preset orientation information M are matched, the loading seat F24 moves downward to place the object to be cut W on the platform B1, so that the object to be cut W is held on the placement surface B11 by negative pressure adsorption. After the object to be cut W is placed on the platform B1, the platform B1 returns to the initial orientation to await subsequent cutting operations.

[0152] After the object to be cut W is placed on the platform B1, the platform B1 is driven to move horizontally to one side of the machine body A so that the object to be cut W can be cut by the cutting device G. During cutting, the cutting imagers G41 on both sides of the cutting mechanism G3 tilt to capture images of the side surface of the object to be cut W on the platform B1 to obtain the orientation information of the cutting line W1 and align the cutting line W1 with the cutting blade G31. Then, by the vertical displacement of the cutting mechanism G3 of the cutting device G, the cutting blade G31 of the cutting mechanism G3 cuts the object to be cut W according to the cutting line W1. Wherein, the alignment of the cutting line W1 with the cutting blade G31 is achieved by the control unit H controlling the platform B1 to rotate or move horizontally along the Y-axis so that the cutting line W1 aligns with the cutting blade G31 when the cutting blade G31 is not moved.

[0153] After the object W is cut, the unloading mechanism F3 moves horizontally above the platform device B, and the unloading seat F32 moves downward so that the suction nozzle F33 can pick up the cut object W on the platform B1. After the suction nozzle F33 picks up the cut object W, the unloading seat F32 moves upward to remove the cut object W from the platform device B, and the unloading mechanism F3 moves horizontally above the receiving device E, and the unloading seat F32 moves downward to move the cut object W into the receiving device D.

[0154] In the material feeding method and cutting device of this invention embodiment, before the material to be cut W is transferred to the platform B1 by the loading mechanism F2, the material to be cut W is imaged by the feeding imager C21. The control unit H can adjust the orientation of the transferred material to be cut W or the orientation of the platform B1 according to the image acquisition result; thereby, the orientation of the material to be cut W is adjusted during the transfer, so as to improve the efficiency of the cutting operation.

[0155] Please see Figure 13 As shown, in another embodiment of the present invention, the feed imager C21' is located on the side of the platform B1 of the feed device C relative to the platform device B. The feed imager C21' captures an image of the lower surface of the object to be cut, which is held by the suction nozzle F25 below the loading seat F24 of the loading mechanism F2, from bottom to top.

[0156] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the invention shall still fall within the scope of the patent of the present invention.
