Description

Equipment and method for processing symmetrical unequal pitch cutter wheel

The present invention relates to a cutter wheel machining equipment, and in particular, to a symmetrical unequal pitch cutter wheel machining equipment for machining a cutter wheel with symmetrical and unequal pitch teeth.

With the rapid development of fifth-generation mobile communication technology and artificial intelligence, flat-panel display products in the semiconductor industry and image display industry have gradually become one of the key points of industrial development. Generally speaking, flat panel display products mostly use glass materials as substrates and undergo a series of processing. However, due to the poor ductility and weak stress resistance of the glass, when the glass substrate is cut carelessly, it is likely to cause cracks or even breakage of the glass substrate due to radial, transverse or longitudinal stress. Therefore, glass cutting processing is one of the important key technologies in the manufacturing process of flat panel display products.

In the processing technology of glass cutting, laser cutting is one of the common processing methods. Since the converged laser beam has good linearity and penetration and is non-contact processing, the cutter of the laser cutting equipment will not be damaged and the glass can be cut quickly. However, laser cutting equipment is relatively expensive. In addition, laser beams will produce convergence and bifurcation effects and thermal effects when cutting glass, which will easily cause defects or deteriorated layers on the edges of the glass, resulting in fragmentation problems in subsequent transportation or post-production processes, thereby reducing product quality. Therefore, some manufacturers also process glass by diamond wheel cutting.

In the existing diamond cutter wheel, the diamond cutter wheel includes a plurality of cutter teeth, and the diamond cutter wheel moves on the glass substrate through the cutter teeth to cut the glass. The teeth of the diamond cutter wheel are mostly laser cut to process a plurality of depressions on the diamond cutter wheel so as to form the teeth between the two depressions. Due to the large number of teeth of the diamond cutter wheel and laser cutting can only process one depression at a time, it takes a lot of time and cost to process the teeth by laser cutting. In order to shorten the processing time of the cutter teeth, the cutter teeth processed by laser cutting are extremely shallow, which will easily cause filling of the depressions between the cutter teeth and affect the cutting quality. Moreover, the existing diamond cutter wheels are all designed with equal teeth. Therefore, when the diamond cutter wheel cuts glass, the teeth of the diamond cutter wheel will produce regular cutting frequency, and the glass substrate may produce regular vibration spectrum and stress concentration due to the regular cutting frequency of the diamond cutter wheel, resulting in cracks or even cracks in the glass, which will increase the cost and reduce the cutting quality.

Therefore, it is necessary to develop a new type of cutter wheel processing equipment to solve the problems of the prior art.

In view of this, one scope of the present invention is to provide a symmetrical unequal pitch cutter wheel processing equipment to solve the problems of the prior art.

According to a specific embodiment of the present invention, the symmetrical unequal pitch cutter wheel processing equipment includes an indexing device, a first grinding tool and a second grinding tool.

Wherein, the cutter wheel has a cutting portion. The first grinding tool is arranged on one side of the cutter wheel and used for grinding the cutting part of the cutter wheel. The second grinding tool is symmetrically arranged on the other side of the cutter wheel relative to the first grinding tool. The second grinding tool is used for grinding the cutting part of the cutter wheel. Among them, the indexing device drives the cutter wheel to rotate to multiple angles, And the plural angles are variable angles. The first grinding tool and the second grinding tool grind the cutter wheel according to a plurality of angles to generate a plurality of grooves on the cutting portion, so that the cutting portion of the cutter wheel forms a plurality of teeth with symmetrical unequal pitches.

Wherein, the first grinding tool rotates clockwise to grind the cutter wheel, and the second grinding tool rotates counterclockwise to grind the cutter wheel.

Wherein, the plurality of angles are arranged in an increasing manner, and the indexing device rotates the cutter wheel to the plurality of angles in sequence.

The first driving element is used to drive the first grinding tool to rotate, and the second driving element is used to drive the second grinding tool to rotate.

Further, the symmetrical unequal pitch cutter wheel processing equipment includes a correction mechanism connected to the second grinding device. The calibration mechanism is used to adjust the position of the second grinding device, so that the second grinding tool of the second grinding device is collinear with the first grinding tool of the first grinding device.

Wherein, the symmetrical unequal-pitch cutter wheel processing equipment further includes a controller connected with an indexing device, a first grinding tool and a second grinding tool, and the plural angles include a first angle and a second angle. The controller first controls the indexing device to rotate the knife wheel to a first angle, then controls the first grinding tool and the second grinding tool to grind the knife wheel, and then controls the indexing device to rotate the knife wheel to a second angle.

Wherein, the cutting part of the cutter wheel has a cutter wheel angle, and the cutter wheel angle is between 60 degrees and 120 degrees.

Another scope of the present invention is to provide a symmetrical unequal pitch cutter wheel machining method to solve the problems of the prior art.

According to a specific embodiment of the present invention, the method for processing a symmetrical unequal pitch cutter wheel includes the following steps: erecting the cutter wheel on an indexing device; symmetrically arranging a first grinding tool and a second grinding tool on both sides of the cutter wheel; the indexing device drives the cutter wheel to rotate to a plurality of angles; and the first grinding tool and the second grinding tool sequentially grind the cutter wheel according to the plurality of angles, so that the cutting part of the cutter wheel produces a plurality of grooves and forms a plurality of teeth of symmetrical unequal pitches.

Wherein, in the step of grinding the cutter wheel sequentially by the first grinding tool and the second grinding tool according to a plurality of angles, so that the cutting part of the cutter wheel produces a plurality of grooves and forms a plurality of symmetrical knife teeth with unequal pitches, the following steps are further included: the first grinding tool rotates in a clockwise direction, and the second grinding tool rotates in a counterclockwise direction; and the first grinding tool and the second grinding tool grind the cutter wheel at a plurality of angles in sequence.

Wherein, the machining method of the symmetrical unequal pitch cutter wheel further includes the following steps: correcting the second grinding tool so that the second grinding tool is collinear with the first grinding tool.

To sum up, the symmetrical unequal-pitch cutter wheel processing equipment of the present invention can rotate multiple different angles of the indexing device and perform grinding processing, so that the cutter wheel can form a plurality of cutter teeth with unequal pitches, and the cutter wheel can suppress regular glass vibration and release stress when cutting glass without causing cracks and breakage of the glass, thereby reducing processing costs and improving cutting quality. Moreover, the symmetrical unequal-pitch cutter wheel processing equipment of the present invention can simultaneously process the cutter wheel through the symmetrically arranged first grinding tool and the second grinding tool, so as to achieve the function of double the gear making speed, thereby improving the processing efficiency and reducing the processing time cost. In addition, the symmetrical unequal pitch cutter wheel processing equipment of the present invention can also be processed by cutting in the same direction through the first grinding tool and the second grinding tool. The knife wheel makes the knife wheel produce symmetrical and consistent knife teeth, which improves the quality of the knife wheel and the cutting quality.

FIG. 3 is a schematic diagram illustrating the connecting rod 112 , the first grinding tool 121 , the second grinding tool 131 and the cutter wheel 5 in FIG. 1 . As shown in FIG. 1 and FIG. 3 , in this specific embodiment, the symmetrical unequal pitch cutter wheel processing equipment 1 includes an indexing device 11 , a first grinding tool 121 and a second grinding tool 131 . The indexing device 11 is used to fix a cutter wheel 5 , and the cutter wheel has a cutting portion 51 .

Moreover, the lifting mechanism 102 can drive the indexing device 11 to move up and down along the Z-axis direction. In practice, the lifting mechanism 102 can be a cylinder, a screw, a slide rail, and the like.

In this specific embodiment, the indexing device 11 has a rotating shaft 111 . Indexing device 11 is used to fix the cutter wheel 5 and drive the cutter wheel 5 to rotate with the rotating shaft 111 as the axis. In practice, the indexing device 11 may include a sleeve structure (not shown) and a connecting rod 112, and the cutter wheel 5 may include a hole (not shown). The sleeve structure of the indexing device 11 can cover and clamp one end of the connecting rod 112 , and the cutter wheel 5 can pass through the connecting rod 112 through the hole and be fixed on the other end of the connecting rod 112 . When the indexing device 11 rotates at an angle, the sleeve structure of the indexing device 11 rotates to the angle with the rotating shaft 111 as the axis. At this time, the sleeve structure drives the connecting rod 112 to rotate, and then drives the cutter wheel 5 to rotate to this angle. In this specific embodiment, as shown in FIG. 2 , when the indexing device 11 drives the cutter wheel 5 to rotate, the cutter wheel 5 rotates on the XY plane with the rotating shaft 111 as the axis.

In this specific embodiment, the symmetrical unequal pitch cutter wheel processing equipment 1 of the present invention includes a first grinding device 12 and a second grinding device 13 . The first grinding device 12 comprises a first grinding tool 121 and the second grinding device 13 comprises a second grinding tool 131 . The first grinding device 12 and the second grinding device 13 are disposed on the working platform 10 , and the first grinding device 12 and the second grinding device 13 are respectively located on the left and right sides of the indexing device 11 .

In practice, the first driving element and the second driving element can be high-speed motors. In this specific embodiment, the first grinding tool 121 and the second grinding tool 131 rotate along the Y-axis direction, and the first grinding device 12 and the second grinding device 13 are arranged staggered on the X-axis, so that the first grinding tool 121 and the second grinding tool 131 are located on both sides of the cutter wheel 5 on the X-axis.

Further, in this specific embodiment, the symmetrical unequal pitch cutter wheel processing equipment 1 of the present invention includes a correction mechanism 14 . The correction mechanism 14 is connected to the second grinding device 13 and used to adjust The position of the second grinding device 13 on the working platform 10 . In practice, the calibration mechanism 14 may include an adjustment element 141 and a locking element 142 . The adjusting element 141 can be connected to the second grinding device 13 and drive the second grinding device 13 to move, and the locking element 142 can fix the second grinding device 13 on the working platform 10 . The adjusting element 141 can be a micrometer or a screw micrometer, and the locking element 142 can be a screw, but not limited thereto. When the first grinding device 12 and the second grinding device 13 are installed on the working platform 10 , the first grinding device 12 can be fixed on the working platform 10 first. Next, the adjusting element 141 can drive the second grinding device 13 to move until the second grinding tool 131 of the second grinding device 13 is in line with the first grinding tool 121 of the first grinding device 12, and then the locking element 142 fixes the second grinding device 13 on the working platform 10, so that the first grinding device 12 and the second grinding device 13 are symmetrically arranged on both sides of the cutter wheel 5.

It should be noted that when the first grinding device 12 and the second grinding device 13 are arranged on both sides of the cutter wheel 5, the distance between the first grinding tool 121 and the second grinding tool 131 is slightly smaller than the diameter of the cutter wheel 5, so that the first grinding tool 121 and the second grinding tool 131 can grind the cutting portion 51 of the cutter wheel 5. In practice, the distance between the first grinding tool 121 and the second grinding tool 131 can be determined according to the tooth depth requirement, and the calibration mechanism 14 can also adjust the position of the second grinding device 13 to adjust the distance between the first grinding tool 121 and the second grinding tool 131.

Before the cutter wheel 5 is erected on the indexing device 11 , the cutter wheel 5 can be processed with a cutting portion 51 by means of milling, electric discharge machining, etc., and the cutting portion 51 has a cutter wheel angle 52 . In practice, the angle 52 of the cutter wheel can be between 60 degrees and 120 degrees, but not limited thereto, and the angle 52 of the cutter wheel 51 of the cutting portion 51 can also be designed according to requirements. In addition, the symmetrical unequal pitch cutter wheel processing equipment 1 of the present invention may further include a controller for controlling the movement of the lifting mechanism 102 of the working platform 10 , the indexing device 11 , the first grinding device 12 and the second grinding device 13 .

Please refer to FIG. 2 , FIG. 3 and FIG. 4A to FIG. 4C together. FIG. 4A is a schematic structural diagram of a cutter wheel 5 according to a specific embodiment of the present invention. FIG. 4B is a schematic view showing the structure of the cutter wheel 5 in FIG. 4A at another viewing angle. FIG. 4C is an enlarged view of area A in FIG. 4A. Before the symmetrical unequal pitch cutter wheel processing equipment 1 of the present invention processes the cutter wheel 5, the controller can pre-store a plurality of angles, and the controller controls the indexing device 11 to rotate at the plurality of angles in sequence, and then drives the cutter wheel 5 to rotate to the plurality of angles in sequence. In practice, the plurality of angles may include the first angle θ ₁ , the second angle θ ₂ and the third angle θ ₃ . Further, the second angle θ ₂ is greater than the first angle θ ₁ , and the third angle θ ₃ is greater than the second angle θ ₂ , that is to say, the plural angles are variable angles arranged in an increasing manner.

First, the controller controls the indexing device 11 to rotate the cutter wheel 5 to a first angle θ ₁ , and then the controller controls the lifting mechanism 102 to move downward (towards the -Z axis). Since the distance between the first grinding tool 121 and the second grinding tool 131 is smaller than the diameter of the cutter wheel 5, when the controller controls the lifting mechanism 102 to move downward, the first grinding tool 121 and the second grinding tool 131 can contact and grind the cutting portion 51 of the cutting wheel 5, so that the cutting portion 51 of the cutting wheel 5 produces a groove 511. Next, the controller controls the lifting mechanism 102 to move upwards (toward the +Z axis direction) and after the cutter wheel 5 is located above the first grinding tool 121 and the second grinding tool 131, the controller controls the indexing device 11 to rotate the cutter wheel to the second angle _θ2 , and then controls the lifting mechanism 102 to move downward to grind the cutting portion 51 of the cutter wheel 5 and generate a groove 511. Similarly, after the controller controls the lifting mechanism 102 to move upwards (towards the +Z axis direction) and position the cutter wheel 5 above the first grinding tool 121 and the second grinding tool 131, the controller controls the indexing device 11 to rotate the cutter wheel to the third angle _θ3 , and then controls the lifting mechanism 102 to move downwards to grind the cutting portion 51 of the cutter wheel 5 and generate grooves 511.

Since the first grinding tool 121 and the second grinding tool 131 grind the cutting portion 51 of the cutter wheel 5 when the cutter wheel 5 is at an increasing angle, the arc between every two adjacent grooves 511 The length also gradually increases, and then the cutting portion 51 of the cutter wheel 5 forms a plurality of cutter teeth 512 with unequal pitches. When the cutter wheel with unequal pitch cutter teeth cuts glass, the unequal pitch cutter teeth will produce irregular cutting frequency, which can suppress regular glass vibration and release stress, without causing cracks and breakage of glass, thereby reducing processing costs and improving cutting quality.

Furthermore, since the first grinding tool 121 and the second grinding tool 131 are symmetrically arranged on both sides of the cutter wheel 5, when the controller controls the lifting mechanism 102 to move downward, the cutting portion 51 of the cutter wheel 5 will generate two symmetrical grooves 511 at the same time. That is to say, the indexing device 11 only needs to rotate the cutter wheel 5 to 180 degrees to complete the machining of the cutter teeth 512 of the cutter wheel 5 . Therefore, the symmetrical unequal-pitch cutter wheel processing equipment of the present invention can realize the function of double the tooth-making speed through the symmetrical processing of the first grinding tool and the second grinding tool, thereby improving the processing efficiency and reducing the processing time cost.

In addition, as shown in FIG. 3 , in the present embodiment, the first grinding tool 121 rotates in a clockwise direction and the second grinding tool 131 rotates in a counterclockwise direction. In practice, the high-speed motors of the first grinding device 12 and the second grinding device 13 can drive the first grinding tool 121 and the second grinding tool 131 to rotate clockwise. Since the first grinding device 12 and the second grinding device 13 are disposed opposite to each other, that is, the motor shaft of the first grinding device 12 faces the +Y direction, and the motor shaft of the second grinding device 13 faces the -Y direction. Therefore, with respect to the processing plane (X-Z plane) of the cutter wheel 5, the first grinding tool 121 rotates in the clockwise direction, and the second grinding tool 131 rotates in the counterclockwise direction. When the first grinding tool 121 and the second grinding tool 131 processed the cutting portion 51 of the cutter wheel 5, the symmetrical two ends of the cutter wheel 5 were subjected to a downward cutting force (as shown by the arrow in FIG. Therefore, the cutter wheel 5 will not vibrate or skew due to uneven force during processing, so that the first grinding tool 121 and the second grinding tool 131 can grind out the same groove, and the cutter wheel 5 will be symmetrical. And the shape of the knife teeth is consistent, so the quality of the knife wheel and the cutting quality. It should be noted that the rotation mode of the first grinding tool and the second grinding tool is not limited thereto. In a specific embodiment, the first grinding tool can rotate counterclockwise and the second grinding tool can rotate clockwise.

The way the controller controls the indexing device to rotate at a plurality of angles in sequence can be other forms besides the aforementioned specific embodiments. See Figure 5. FIG. 5 is a schematic diagram of a cutter wheel 5' according to an embodiment of the present invention. As shown in FIG. 5 , the difference between this embodiment and the foregoing embodiments is that the plurality of angles (the first angle θ ₁ ', the second angle θ ₂ ', the third angle θ ₃ ', the fourth angle θ ₄ 'and the fifth angle θ ₅ ') in this embodiment are arranged in a tapered manner. The controller can sequentially control the indexing device to rotate the cutter wheel for grinding from large to small angles, and can also form a symmetrical unequal pitch cutter wheel 5'. In another specific embodiment, the controller can only pre-store the first angle and the second angle, and the controller can alternately control the indexing device to rotate the cutter wheel at the first angle and the second angle for grinding. In yet another specific embodiment, the controller can only pre-store the first angle, the second angle, and the third angle, and the controller can control the indexing device to rotate the cutter wheel in order to perform grinding at the first angle, the second angle, and the third angle in multiple cycles.

See Figure 6. FIG. 6 is a flow chart showing the steps of a machining method for a symmetrical unequal pitch cutter wheel according to a specific embodiment of the present invention. The steps in FIG. 6 can be achieved through the symmetrical unequal-pitch cutter wheel processing equipment 1 shown in FIG. 1 and FIG. 2 . As shown in Figure 6, the symmetrical unequal pitch cutter wheel processing method includes the following steps: Step S1: set up the cutter wheel 5 on the indexing device 11; step S2: symmetrically arrange the first grinding tool 121 and the second grinding tool 131 on both sides of the cutter wheel 5; step S3: the indexing device 11 drives the cutter wheel 5 to rotate to a plurality of angles; A plurality of grooves are produced and a plurality of teeth of symmetrical unequal pitches are formed.

See Figure 7. FIG. 7 is a flow chart showing further steps of the machining method of the symmetrical unequal pitch cutter wheel according to FIG. 6 . As shown in FIG. 7 , before performing step S3 , the symmetrical unequal-pitch cutter wheel machining method may further include the following steps: Step S5 : the calibration mechanism 14 calibrates the second grinding tool 131 so that the second grinding tool 131 is collinear with the first grinding tool 121 . In step S4 of FIG. 6 , the following steps can be further performed: Step S41: the first grinding tool 121 rotates in a clockwise direction, and the second grinding tool 131 rotates in a counterclockwise direction;

To sum up, the symmetrical unequal-pitch cutter wheel processing equipment of the present invention can rotate multiple different angles of the indexing device and perform grinding processing, so that the cutter wheel can form a plurality of cutter teeth with unequal pitches, and the cutter wheel can suppress regular glass vibration and release stress when cutting glass without causing cracks and breakage of the glass, thereby reducing processing costs and improving cutting quality. Moreover, the symmetrical unequal-pitch cutter wheel processing equipment of the present invention can simultaneously process the cutter wheel through the symmetrically arranged first grinding tool and the second grinding tool, so as to achieve the function of double the gear making speed, thereby improving the processing efficiency and reducing the processing time cost. In addition, the symmetrical unequal-pitch cutter wheel processing equipment of the present invention can also process the cutter wheel by cutting in the same direction through the first grinding tool and the second grinding tool, so that the cutter wheel produces symmetrical and uniformly shaped cutter teeth, thereby improving the quality of the cutter wheel and cutting quality.
