Description

Captured image forming unit {CAPTURED IMAGE FORMING UNIT}

The present invention relates to a captured image forming unit that forms a captured image of a nozzle means and a captured image of a cutting blade in a cutting device.

A workpiece formed on the surface by dividing a plurality of devices by a division line is divided into individual devices in a cutting device equipped with a cutting blade, and the divided devices are mounted and used in various electronic devices. The cutting device is equipped with a blade cooler nozzle and a shower nozzle. When cutting a workpiece with a cutting blade, cutting water is supplied from the blade cooler nozzle and the shower nozzle to cool the processing heat generated by cutting. Cutting chips generated by cutting are discharged from the upper surface of the workpiece (for example, see Patent Document 1 below).

Since machining precision changes depending on the position of the blade cooler nozzle or shower nozzle with respect to the cutting blade, it is necessary to adjust the position of the blade cooler nozzle or shower nozzle depending on the thickness or outer diameter size of the cutting blade. In particular, when the same machining precision is required for multiple workpieces using multiple cutting devices, it is difficult to adjust the position of the blade cooler nozzle or shower nozzle while determining the position of the cutting blade during cutting. It was difficult to set it in the same position on the device. Therefore, the present applicant proposed a nozzle adjustment jig that can adjust the blade cooler nozzle and shower nozzle to a desired position with high precision (for example, see Patent Document 2 below).

The wheel cover 50 has a center block 51a, and a connection block 51b is connected to the center block 51a. At the lower end of the connection block 51b, a pair of approximately L-shaped blade cooler nozzles 41 are fixed. A pair of blade cooler nozzles 41 extend in parallel from the front 330 side and the back 331 side of the cutting blade 33 shown in FIG. 2 . A plurality of injection holes 41a for spraying cutting water are formed on the inner surface of the opposing blade cooler nozzle 41, aligned in the X-axis direction.

The cutting device 1 shown in FIG. 1 includes a display monitor 18 that displays captured images captured by a captured image forming unit 60 to be described later, processing conditions of the cutting device 1, etc., and records the captured images. It is provided with a recording unit 19 having a recording medium for processing, and control means (not shown) for controlling various mechanisms of the cutting device 1. Recording media include, for example, hard disks, USB memory, CD-R (DVD-R), floppy disks, etc.

[Imaging image forming unit]

The captured image forming unit 60 shown in FIG. 4 is for capturing captured images of the state of the cutting blade 33, blade cooler nozzle 41, and shower nozzle 42 in the above-described cutting device 1. It is an imaging unit. The imaging image forming unit 60 has a main body 600 extending in the horizontal direction (X-axis direction in the illustrated example) and incorporating an imaging mechanism. A recess is formed on the side of the main body 600 near the ) is formed. Additionally, the main body 600 can be transported by, for example, an operator.

As shown in FIG. 5 , the imaging image forming unit 60 includes an imaging means 61 including an imaging element, a surface 330 or a back surface 331 of the cutting blade 33, and a blade cooler nozzle 41. a first optical path 64a reaching from the imaging means 61 to the first window 62 facing the A second optical path 64b reaching the facing second window 63 from the imaging means 61 is provided, and a switching means 65 for switching the first optical path 64a and the second optical path 64b. .

The first window portion 62 is mounted on the first partition 601. The first window portion 62 shown in the example of FIG. 5 faces the front side of the cutting means 30, that is, toward the surface 330 of the cutting blade 33 and the blade cooler nozzle 41. Additionally, the second window portion 63 is mounted on the second partition wall 602 of the main body 600. The second window portion 63 faces the lower side of the cutting means 30, that is, toward the blade tip, which is the outer peripheral tip of the cutting blade 33, and the shower nozzle 42 shown in FIG. Additionally, the material, size, etc. of the first window 62 and the second window 63 are not particularly limited.

The imaging means 61 includes, for example, a camera 610 with a built-in imaging element made of a CCD image sensor or a CMOS image sensor, a beam splitter 611, and a converging lens 612. The beam splitter 611 is disposed between the camera 610 and the converging lens 612 and can reflect the light emitted from the light source 66 and guide it onto the optical path of the condensing lens 612. The condenser lens 612 is not particularly limited, and for example, a wide-angle lens can be used. By using a wide-angle lens, when imaging is taken through the second window 63, it becomes possible to image the injection port 42a of the shower nozzle 42 shown in FIG. 2 due to wide-angle distortion (volume distortion image).

The switching means 65 includes a switching mirror 650 for guiding the light reflected from the beam splitter 611 and condensed into the converging lens 612 to the first optical path 64a or the second optical path 64b, and a switching mirror 650 A rotation mechanism 651 is provided at one end of the mirror 650. By positioning the switching mirror 650 on the optical path of the condensing lens 612 at a predetermined angle using the rotation mechanism 651, the light condensed by the condensing lens 612 is reflected by the switching mirror 650 to form the first optical path. It can be derived from (64a). On the other hand, by retracting the switching mirror 650 from the optical path of the converging lens 612 using the rotation mechanism 651, the light condensed by the condensing lens 612 can be guided to the second optical path 64b. A first mirror 67a is disposed in the first optical path 64a to reflect the light reflected by the switching mirror 650 at a right angle toward the first window 62. In addition, a second mirror 67b is disposed in the second optical path 64b to reflect the light collected by the condenser lens 612 and guided to the second optical path 64b at a right angle toward the second window 63. It is done. Then, by selectively switching the first optical path 64a and the second optical path 64b by the switching means 65, the subject (e.g., For example, the cutting means 30 and the nozzle means 40 can be imaged from the front side, and the subject can be imaged from the lower side through the second window 63. In addition, in this embodiment, the light source 66 is built into the main body 600, but the light source 66 does not necessarily need to be present, and images may be captured using the light within the device.

The captured image forming unit 60 is further provided with a transmission cable connection portion 80 that transmits the captured image captured by the imaging means 61 to the cutting device 1. By connecting the transmission cable connection portion 80 to the connection terminal 18a of the cutting device 1, the captured image captured through the first window portion 62 or the second window portion 63 can be displayed on the display monitor 18. there is. As a result, the height position of the blade cooler nozzle 41 can be adjusted while confirming the positions of the cutting blade 33, the blade cooler nozzle 41, and the shower nozzle 42, and the height position of the shower nozzle 42 can be adjusted. , it becomes possible to adjust the angle and position in the Y-axis direction.

The captured image forming unit 60 is further provided with a connecting portion 81 that connects the captured image captured by the imaging means 61 to a recording portion 19 that records the captured image on a recording medium. By connecting the connection unit 81 to the connection terminal 19a of the recording unit 19, the captured image can be recorded on the recording medium of the recording unit 19. Therefore, the captured image recorded on the recording medium can be used as image data for management recording of the cutting device 1. For example, it is useful when the positions of the blade cooler nozzle 41 and the shower nozzle 42 are set to the same setting in a plurality of cutting devices 1.

As shown in FIG. 4 , the imaging image forming unit 60 is further provided with removal means 70 for removing cutting fluid adhering to the second window portion 63 . The removal means 70 is disposed on the outside of the second partition 602 so as to be movable in the Z-axis direction. In the removal means 70, a plurality of air injection ports 71 are aligned and formed parallel to the X-axis direction. A dry air supply source 73 is connected to each air injection port 71 via a valve 72. By opening the valve 72, dry air can be sprayed from the air injection port 71 to remove the cutting fluid adhering to the second window portion 63. Here, when taking an image from the second window 63, the cutting fluid is sprayed from the shower nozzle 42 and the degree of spraying of the cutting fluid on the cutting blade 33 is observed. Air is blown to remove the cutting fluid, but if the air is blown in the direction opposite to the direction in which the cutting fluid is sprayed from the shower nozzle 42, there is a risk that the blown cutting fluid or injected air may collide with the cutting fluid. In this embodiment, the removal means 70 is configured to be capable of being raised and lowered, so that air is blown in the same direction as the cutting fluid. As a result, cutting fluid can always be removed from the second window 63, and a desired captured image can be captured clearly through the second window 63.

In the sensing image forming unit 60 shown in the present embodiment, the two removal means 70 are disposed so as to sandwich both sides of the second window portion 63, so that the single spindle 31 described above is used. In addition to the cutting device 1 having a single-axis structure, it can also correspond to a cutting device having a two-axis structure (not shown) having two spindles. In a cutting device with a two-axis structure, the rotation directions of the first spindle and the second spindle are opposite to each other. Since the shower nozzle sprays cutting fluid in the same direction as the rotation direction of the cutting blade, the arrangement of the shower nozzle on the first spindle side and the shower nozzle on the second spindle side becomes symmetrical with respect to the spindle. Therefore, when imaging the first spindle through the second window 63, the removal means 70 on the side where the shower nozzle is located on the first spindle side is raised, and the removal means 70 on the opposite side is used to remove the removed cutting. Move it downward so as not to disturb the flow of liquid. On the other hand, when imaging the second spindle through the second window 63, the removal means 70 on the side of the second spindle where the shower nozzle is located is raised, and the removal means 70 on the opposite side is raised in the same manner as above. , Retract it downward so as not to disturb the flow of the removed cutting fluid. In addition, the removal means 70 shown in this embodiment is configured to remove cutting fluid by air blowing, but is a mechanism for physically removing cutting fluid adhering to the second window portion 63 using, for example, a wiper or the like. You can configure it.

The captured image forming unit 60 further includes a fixing portion 90 that fixes the captured image forming unit 60 to the spindle housing 32 . The fixing part 90 is made of, for example, a magnet. The fixing portion 90 shown in this embodiment is disposed at the upper end of the attaching and detaching block 91 mounted on the main body 600 so as to be connected to the second partition 602. By fixing the fixing part 90 to the lower part of the spindle housing 32 by magnetic force, the imaging image forming unit 60 can be easily fixed to the spindle housing 32. This allows the captured image forming unit 60 to be positioned at a position where a desired captured image can be captured, that is, to position the cutting blade 33, the blade cooler nozzle 41, and the shower nozzle 42 in the concave portion of the main body 600. You can.

The sensing image forming unit 60 may be held on the holding surface 21a of the holding table 21. In this case, after removing the attachment/detachment block 91 from the main body 600 and placing the main body 600 on the holding surface 21a of the holding table 21, the main body 600 is placed on the holding surface 21a. Suction is maintained. In this way, even when the captured image forming unit 60 is held by the holding table 21, the captured image forming unit 60 can be positioned at a position where a desired captured image can be captured.

Next, an example of use of the sensing image forming unit 60 in the cutting device 1 will be described. In the present embodiment, as shown in FIG. 5, the pickup image forming unit 60 is used by being fixed to the spindle housing 32 by the fixing portion 90.

When capturing an object from the front through the first window 62 using the imaging image forming unit 60, the connecting block 51b of the wheel cover 50 is viewed from the front in advance, as shown in FIG. 6. Just move it to the left and keep it away from the central block (51a). The illustrated imaging area P represents a range in which the imaging means 61 can capture images through the first window 62, and the imaging area P includes the surface 330 of the cutting blade 33 and the blade cooler. A nozzle (41) and a shower nozzle (42) are included. For example, when adjusting the height position or angle of the shower nozzle 42, cutting fluid ( 43) is supplied. The cutting fluid 43 sprayed from the injection port 42a of the shower nozzle 42 contacts the outer peripheral tip of the cutting blade 33. During the injection of the cutting fluid 43, the removal means shown in FIG. 4 is located in the same direction as the shower nozzle 42 with respect to the spindle 31 (the injection direction of the cutting fluid 43 and the air blow direction are the same direction). (70) is used. That is, the removal means 70 on the side where the shower nozzle 42 is on the spindle 31 side that is the imaging target is raised, the removal means 70 on the opposite side is retracted downward, and the cutting fluid 43 is released. Dry air is sprayed from the air injection port 71 of the removal means 70 in the same direction as the spraying direction to remove the cutting fluid 43 adhering to the second window portion 63. In the case of taking images while spraying the cutting fluid 43, the cutting fluid 43 rotates with the rotation of the spindle 31, so that the degree of spraying of the cutting fluid 43 on the cutting blade 33 becomes unclear. To prevent this, it is desirable not to rotate the spindle 31.

The switching means 65 shown in FIG. 5 uses a rotation mechanism 651 to move the switching mirror 650 to a position inclined at a predetermined angle indicated by a dotted line in FIG. 5 on the optical path of the converging lens 612. Accordingly, the light emitted from the light source 66 is guided to the first optical path 64a by the switching mirror 650, passes through the first window 62, and is reflected in the imaging area P. The imaging element of the camera 610 receives the reflected light, thereby photoelectrically converting the object image to form the captured image 100 shown in FIG. 7 . The captured image 100 is displayed on the display monitor 18. In addition to the captured image 100, the display monitor 18 includes, for example, the distance (1 mm) between two dotted lines indicating the height of the blade cooler nozzle 41 and the injection port 42a of the shower nozzle 42. The angle θ (62.6°) indicating the direction is also indicated. The edge position of the cutting blade 33, the height position of the blade cooler nozzle 41, and the height position and angle of the shower nozzle 42 are displayed in the captured image 100 by, for example, the control means of the cutting device 1. It is detected based on The control means automatically identifies the edge position of the cutting blade 33, the height position of the blade cooler nozzle 41, the height position and angle of the shower nozzle 42, etc. from the captured image 100, and the cutting blade The position of the blade tip of (33), the height position of the blade cooler nozzle 41, and the height position of the shower nozzle 42 may be specified by the operator on the display monitor 18, and the control means may calculate the distance or angle. .

When the angle θ of the shower nozzle 42 captured in the captured image 100 is not at a predetermined angle, the operator adjusts the angle adjustment screw 55 while viewing the captured image 100. After loosening, the direction of the shower nozzle 42 is adjusted to a predetermined angle θ, and then the angle adjustment screw 55 is tightened to adjust the angle of the shower nozzle 42. Also, for example, when the height position of the shower nozzle 42 is high relative to the blade tip of the cutting blade 33, the operator connects the shower nozzle 42 with the height position adjustment screw 54 while viewing the captured image 100. The shower nozzle 42 is lowered together with the block 51c and adjusted to a predetermined height position.

Also, for example, when the height position of the blade cooler nozzle 41 in the captured image 100 is lower than the blade tip tip of the cutting blade 33, the operator, while viewing the captured image 100, adjusts the height position adjustment screw. The blade cooler nozzle 41 is raised together with the connection block 51b by (53) and adjusted to a predetermined height position. Here, the desired height of the blade cooler nozzle 41 is below the outer periphery of the nut 36 so that the blade cooler nozzle 41 does not interfere with the nut 36, and the cutting blade 33 is not worn. In order to prevent the blade cooler nozzle 42 from contacting the upper surface of the workpiece even if the blade tip extension is shortened, the lower end of the blade cooler nozzle 41 indicated by one dotted line (S1) in FIG. 7 is aligned with the other dotted line (S2). Adjust so that it is above the outer periphery of the front flange 35, indicated by . Additionally, when adjusting the height position of the blade cooler nozzle 41, it is not necessary to spray cutting fluid from the blade cooler nozzle 41. The cutting fluid sprayed toward the front and back surfaces of the cutting blade 33 by the blade cooler nozzle 41 is supplied to the machining point via the flange or the cutting blade 33, so the blade cooler nozzle 41 itself is a nut. (36) Any position that does not contact the workpiece will suffice. Accordingly, there is no need to adjust the position of the blade cooler nozzle 41 while supplying cutting fluid to the cutting blade 33 from the blade cooler nozzle 41.

When capturing an object from below through the second window 63 using the imaging image forming unit 60, the switching means 65 shown in FIG. 5 switches the switching mirror 650 by the rotation mechanism 651. is retracted from the optical path of the converging lens 612 to the position indicated by the solid line in FIG. 5. Accordingly, the light emitted from the light source 66 is guided to the second optical path 64b, passes through the second window portion 63, and is reflected by the edge of the cutting blade 33 and the lower side of the shower nozzle 42. . The imaging element of the camera 610 receives the reflected light, thereby photoelectrically converting the object image to form the captured image 200 shown in FIG. 8 . The captured image 200 is displayed on the display monitor 18. In addition to the captured image 200, the display monitor 18 also displays, for example, a distance (0.1 mm) indicating the amount of positional deviation between the center of the cutting blade 33 and the center of the jet port 42a of the shower nozzle 42. are displayed together. The position of the shower nozzle 42 in the Y-axis direction is detected based on the captured image 200 by the control means of the cutting device 1, for example. Additionally, in addition to the automatic determination by the control means, the position of the shower nozzle 42 in the Y-axis direction may be specified by the operator as a predetermined value on the display monitor 18 and calculated by the control means.

In this embodiment, the center line L1 passing through the center of the jet port 42a of the shower nozzle 42 captured in the captured image 200 and the center line L2 passing through the center of the thickness direction of the cutting blade 33 are misaligned. At this point, while viewing the captured image 200, the operator loosens the position adjustment screw 56 shown in FIG. 3 and then moves the shower nozzle 42 in the Y-axis direction to align the center line L1 and the center line L2. ) Adjust the position of the shower nozzle 42 in the Y-axis direction so that it matches. Afterwards, tighten the positioning screw (56).

When adjusting the position or angle of the shower nozzle 42, it is preferable that the cutting fluid is sprayed from the spray port 42a of the shower nozzle 42. If the center of the shower nozzle 42 deviates from the center of the cutting blade 33, the balance of the quantity of cutting fluid supplied to the front and back surfaces of the cutting blade 33 will be lost, causing bending (meandering) of the cutting blade 33. Since there is a concern, the position of the shower nozzle 42 can be adjusted with good precision by capturing the state in which the cutting fluid is actually sprayed from the injection port 42a with the camera 610. Alternatively, the nozzle may be adjusted while spraying cutting fluid from the shower nozzle 42. After adjusting the position and angle of the shower nozzle 42, the state in which the cutting fluid is sprayed is captured again with the imaging means 61. You can check it.

In this way, the imaging image forming unit 60 according to the present invention includes an imaging means 61 including an imaging element, the surface 330 or the back surface 331 of the cutting blade 33, and the blade cooler nozzle 41. a first optical path 64a reaching from the imaging means 61 to the first window 62 facing the Since the facing second window 63 is provided with a second optical path 64b reaching from the imaging means 61 and a switching means 65 for switching the first optical path 64a and the second optical path 64b. , with one captured image forming unit 60, the cutting blade 33, blade cooler nozzle 41, and shower nozzle 42 can be imaged in the same captured image. Therefore, according to the present invention, the nozzle can be easily adjusted based on the thickness or position of the cutting blade 33.

Additionally, the order of nozzle adjustment is not particularly limited. After adjusting the position of the blade cooler nozzle 41, the position or angle of the shower nozzle 42 may be adjusted, or after adjusting the position or angle of the shower nozzle 42, the position or angle of the blade cooler nozzle 41 may be adjusted. You can adjust it.

The captured images 100 and 200 shown in the above embodiment were used when adjusting the nozzle, but, for example, the blade cooler nozzle 41 and the shower nozzle 42 are periodically captured and the captured images are stored in the recording unit 19. You may record it. If the captured image captured through the first window 62 or the second window 63 is recorded on the recording medium of the recording unit 19, it can be used as image data for management recording of the cutting device 1, for example. . Using the captured image recorded on the recording medium, the positions of the blade cooler nozzle 41 and the shower nozzle 42 in the plurality of cutting devices 1 can be set to the same setting.

Although the captured image forming unit 60 shown in the above embodiment has a structure independent of the cutting device 1, the captured image forming unit 60 may be mounted within the device.
