Description

Automatic regrind device for drill bit

The present invention relates to an automatic regrind device for a drill bit which can be automatically tuned by a reciprocating cutting end of a processing bit of a printed circuit board and which is shortened by regrind.

The board is for the purpose. Since the diameter of the through hole is very small, the drill bit that penetrates the fine through hole also has a cutting end having a very small diameter.

The cutting end of the above drill bit is basically made of a very hard wear resistant material such as carbide, but after a certain number of holes are processed, the bit diameter of the drill hole cannot be continuously satisfied for the standard diameter of the hole. Its tolerance is allowed. In this way, if the cutting end of the drill bit is passivated, it is more advantageous than the replacement of the new drill bit and the grinding is more cost-effective. Therefore, the development of the bit regrind device is on the rise.

Recently, in the state of the Korean Patent Registration No. 10-745665, in the state in which the drill holder has a drill holder in combination with the drill, the rotary body is rotated in stages, and the automatic regrinding device for the re-grinding process is continuously performed. .

However, in the former automatic regrind device, the drill bit was joined by the outer circumference of the drill holder through the conventional integral retention exposure length. Since only the automatic position adjustment portion can be engaged, the device structure is not only complicated, but also the drill bit is automatically referred to. The position adjustment part, after the position adjustment is completed, the drill bit has to be recovered again, and many working hours are required. Moreover, the above-mentioned old automatic regrind device, the scrap generated during the re-grinding of the drill bit is stuck to the cutting end of the drill bit, and causes a problem when reused. Furthermore, the automatic regrind device described above cannot be grasped and re-grinded after completion of re-grinding. To the extent that the regrind bit is used again, problems can arise from time to time.

On the other hand, in the process of using each bit, the degree of wear varies, and the length of the cutting end is different; so when the grinding bit is mounted on the drilling machine and then used again, in order to avoid the difference in the distance between the front end of the machining bit and the cutting end of the drill bit, The positioning ring 13 clamps the body portion 12 of the drill bit 10 as shown in FIG. This positioning ring 13 is set at a certain distance from the cutting end 11 of the drill bit 10, so that the drill bit 10 is accurately fixed to the drill holder each time.

The position of the positioning ring 13 is thus only re-polished and reformed; since the length of the cutting end 11 of the drill bit 10 becomes shorter during the re-grinding process. If the position of the positioning ring 13 is not readjusted, the distance between the front end of the drilling machine and the cutting end 11 of the drill bit 10 is different when the machining drilling machine is used again, and thus the depth of the through hole on the printed circuit board is different. However, in the past, the field operator used the measuring instrument such as the vernier caliper to measure the distance between the cutting end 11 of each of the drill bits 10 and the positioning ring 13, and then adjusted the position of the positioning ring 13 by hand, so that the operability is not only very bad. The productivity is greatly reduced, and the operator's proficiency is also increased in precision and operating speed.

Further, when the drill 10 is lowered by the drill pusher 620, it is preferable to add the vertical bracket 623 supported by the lower portion of the drill holder 611 without damaging the drill holder 611 under the load permitted by the drill holder 611.

In this manner, in the case where the vertical bracket 623 is provided, the elastic isolation is provided from the upper portion of the turntable 610 without disturbing the vertical bracket 623 from the movement of the drill holder 611 following the turntable 610. For this purpose, in the center of the drill holder 611, the pins 611b of the turntable 610 are vertically inserted, and the pins 611b are in contact with the bottom surface of the turntable 610, so that the pins 611b are prevented from being unwound from the turntable 610, and the stopper 611c is provided.

Further, the elastic member 611d is joined to the lower end of the pin 611b; the elastic member 611d can be sandwiched and joined at the lower end of the pin 611b, and a compression coil spring (Coil Spring) is preferably used. In the present practical example, in order to smoothly raise and lower the drill holder 611, the drill holder 611 is provided. The end also engages the pin 611b. At the same time, the lower end of the turntable 610 is a support bracket (611e); on the side of the bracket 611e, a through hole 611f is formed for the lower end of the pin 611b to pass through, so that the lifting and lowering of the drill holder 611 is not hindered. .

Therefore, the elastic member 611d is supported by the upper end of the stopper 611c, is inserted into the lower side of the bracket 611e in a supported state and inserted under the pin 611b, and is provided with a suspension force to the drill holder 611, and the drill holder is attached. When the 611 is lowered, the stopper 611c is pressed and the elastic side is deformed.

As shown in FIGS. 24 and 26, the positioning ring transfer combination 640 disposed at the second position of the second stage of rotation of the turntable 610 is disposed on the lower side of the drill holder 611 at the second position, and the drill bit 10 is mounted on the drill holder 611. The lower end is pushed up at a certain height, and is pushed up and lowered by the push rod 641 and the support base 612 on the upper side of the drill holder 611, and the side of the push rod 641 is lowered after the movement of the push rod 641 is completed, and the positioning ring 13 is pushed down.

The lower portion of the positioning ring push rod 642 is formed such that the outer end of the cutting end 11 of the drill 10 inserted into the insertion hole 642a is exposed, and the through hole 642b communicating with the insertion hole 642a is formed.

<Fourth optical inspection machine>

As shown in FIG. 21 and FIG. 24 or FIG. 26, the fourth optical inspection machine 630 of the present invention photographs the camera 631 and the illumination 632 at the cutting end of the drill 10, and follows the position of the positioning ring push rod 642 descending through the hole 611f. The drill bit 10 is cut at the cutting end 11 setting. And the fourth optical The inspection machine 630 transmits the position information of the photographed drill bit 10 to the positioning ring push rod 642; on the other hand, the distance h from the side of the through hole 611f and the lower end of the push rod of the positioning ring 13 is the cutting end 11 of the drill bit 10 and the positioning ring 13 The distance h between the set points is the same.

Therefore, as shown in FIG. 26 and FIG. 27, if the position of the cutting end 11 of the drill 10 and the side of the through hole 642b are on the same line, it is equal to the positioning ring push rod 642 to move the positioning ring 13 to the setting point, and the positioning ring push rod When the position of the fourth optical inspection machine 630 transmitting the through hole 642b coincides with the cutting end 11 of the drill 10, the lowering operation is interrupted in time. Further, as shown in FIGS. 28 and 29, in the third position in which the third stage of the turntable 610 is rotated, the positioning ring 13 is fixed from the drill holder 611, and the drill 10 is loaded and unloaded and then reversed, and the drill holder 611 can be set again. The reversal site 650 is installed.

The position of the cutting end 11 of the drill bit 10 which is reversed by the reversing portion 650 to the lower portion of the drill holder 611 is exposed.

The reason for reversing the drill bit 10 is that the cutting end 11 faces downward, and the cutting end 11 is damaged in order to avoid peeling of the drill bit 10 from the drill holder 611. At the same time, as shown in FIG. 30, in the fourth position of the fourth stage of rotation of the turntable 610, the reversed state releases the drill 10 which is placed in the drill holder 611, and the bit 10 is transferred to the stored bit unloading automatic device 700 and then added. .

<Drill Unloading Automatic Equipment>

As shown in FIGS. 2 and 31, the drill unloading robot 700 is disposed at the fourth rotational position of the rotary body 100, and conveys the drill 10 that has been ground or washed or has the positioning ring 13 fixed to the drill storage box B. That is, the drill bit 10 of the above-described drill unloading automatic device 700 is finished or the washing is completed. The operation of the fixing unit to be unloaded and transferred to the drill storage box B.

If the positioning ring aligner 600 is set, the drill unloading automatic device 700 unwinds the ground drill 10 from the drill holder 130, supplies it to the positioning ring aligner 600, and sets the locating ring 13 to the drill bit. 10, the action of moving to the bit safe deposit box B is released. When the washing machine 500 and the positioning ring aligner 600 are all set, the bit unloading automatic device 700 completes the washing, and the third optical inspection machine 550 determines that the good bit 10 is unwound from the drill holder 130 and is supplied to the positioning ring for setting. The device 600 completes the action of the drill bit 10 of the positioning ring 13 being unwound from the positioning ring setter 600 and transferring the bit to the bit holder B. At the same time, the bit unloading automatic device 700 is provided with the positioning ring aligner 600, so that the drill bit 10 is unwound from the bit holder 130 and the positioning ring aligner 600, in order to perform the action efficiently, the first unloading portion 710 and the second The composition of the blanking portion 720 is ideal.

That is, the first blanking portion 710 disengages the drill bit 10 from the drill holder 130 and provides its action to the positioning ring setter 600, and the second blanking portion 720 disengages the drill bit 10 from the positioning ring adjuster 600. Transfer to the drill deposit box.

That is, the first blanking portion 710 is a slider 711 that is provided to move from a certain height of the bottom surface to the z-axis direction, and a y-axis transfer unit (712 that is movable up and down) is provided on the slider 711, and the y-axis transfer unit (712) The lower end is provided with a clamp fixing portion 713 which is fixed on both sides of the drill bit 10. The fixed portion 713 is a rotating body 100 located in the x-axis direction, and is disposed on the drill holder 130 to disengage the drill bit 10 and is rotatable about the z-axis. The second blanking portion 720 is not rotatable except for the clamp fixing portion 713, and the rest is different from the first blanking portion 710, and detailed description thereof will be omitted.

At the same time, the composition of the present invention is to re-grind the drill bit by the same process as below. First, the drill supply tank A is moved to the first rotational position to the side of the drill loading automatic device 300, and the drill loading automatic device 300 is brought close to the drill supply tank A, and the drill bit supply box A is first received and the drill bit 10 is the object to be polished. Then, the drill holder 130 provided in the front rotary body 100 is loaded. At this time, the unlocking combination 150 provided in front of the drill holder 130 is raised to the locking sleeve 141 of the drill holder 130, and then moved toward the locking sleeve 141 side, and the clamping of the chuck 140 is released. status.

If the drill bit 10 is loaded on the drill holder 130, the first optical inspection machine 200 measures the distance from the front end of the drill holder 130 to the cutting end of the drill bit 10 so that the cutting end of the drill bit 10 is at the reference position, and the position adjustment information is loaded into the drill bit automatic device. 300 transmission.

The bit loading robot 300 that receives the position adjustment transmission information controls the operation of the slider 310 and adjusts the cutting end position of the drill 10. At the same time, the bit loading robot 300 loads the drill bit 10 in the state of the drill holder 130, receives the information of the transfer position adjustment from the first optical inspection machine 200, and directly arranges the drill bit 10, and the bit 10 installation process is completed very quickly. .

On the other hand, when the cutting end of the drill bit 10 is at the standard position, the clamp release combination 150 is lowered, and as a result, the lock sleeve 141 is returned to the original position, and the chuck 140 chucks the drill bit 10. After the bit 10 is clamped, the bit loading robot 300 is returned to its original position, and then the bit 10 is ready for loading. While the bit loading robot 300 is returned to the original position, the rotating body 100 rotates the turntable 111 to the second rotational position. At the same time, the drill 10 is mounted on the drill holder 130 and also moves in the second rotational position. In the second rotation In the turning position, the drill 10 is re-ground according to the re-grinding machine 400 disposed in front; before the re-grinding, in order to prevent the vibration from being transmitted from the re-grinding machine 400 to the drill bit 10 during re-grinding, the re-grinding cannot be performed precisely, The rotating body 100 elevator 150 is disposed in front of the second rotational position, and the support assembly 151 is supported by the cutting end of the ascending drill 10.

At this time, the chuck 131 is continuously and stably horizontally passed through the chuck supporting unit 133; in the case where the seating recess 152 is formed at the upper end of the support assembly 151, the cutting end of the drill bit 10 is properly installed at the bit seating recess 152, while not The state of moving to the left and right sides. The cutting end of the drill bit 10 is stably supported by the support assembly 151, and the cutting end height of the drill bit 10 is measured at the first optical inspection machine 200. Each time the outer diameter of the cutting end of the drill bit 10 changes, since the cutting end height is different, the first optical inspection machine 200 photographs the cutting end of the drill bit 10, and the height information thereof is transmitted to the control portion.

The control unit that receives the height information determines how much the cutting end height differs from the standard height to calculate the adjustment distance, and then controls the elevator 150 to operate, and rotates the drill 100 million to the standard side of the joint 132, and adjusts the height of the drill 10 at the cutting end. The specific observation is the same as the following except that the cutting end height adjustment process of the drill bit 10 is performed. The control unit first lowers the tie rod of the vertical cylinder 134a; if the tie rod of the vertical cylinder 134a is lowered, the lift joint 133b is attached to the guide 134c in a state where the lift buckle 134b is attached, and the pull rod lift combination 133b of the vertical cylinder 134a is lowered. As a result, the chuck 131 is freely rotated up and down to the center of the universal joint.

Further, in the case where the cutting end height of the drill bit 10 is higher than the standard height, the elevator 150 is driven to descend, and the control portion lowers the support assembly 151. Following the support assembly 151 descending, the collet 131 is rotated downward according to its own weight by the universal joint 132 standard; the result is the cutting end of the drill bit 10 as shown in FIG. In the state in which the support set 151 the bit seating recess 152 is properly mounted, the support assembly 151 is lowered and the height side is lowered.

In the case where the cutting end height of the drill bit 10 is lower than the standard height, the control unit lowers the driving of the elevator 150 to raise the support assembly 151. Following the rise of the support assembly 151, the collet 131 is rotated upwardly by the universal joint 132; as a result, the height of the cutting end of the drill bit 10 rises as shown in FIG. On the other hand, in the case where the elevator 150 is further provided with the elevating guide 153, after the cutting end height of the drill bit 10 reaches the standard position, the elevating guide 153 is lowered while covering the upper portion of the drill bit 10. At this time, the pair of pressurizing projections 153a The upper part of the cutting end of the drill bit 10 is pressurized. At the same time, the drill bit 10 is in a state of being stably supported in the bit seating recess 152, and does not have to be moved during re-grinding, and can be precisely processed. And the angle of the cutting end of the drill bit 10 is checked by the second optical inspection machine 460.

The second optical inspection machine 460 photographs the front end of the cutting end of the drill bit 10, and checks whether the angle formed by the cutting end coincides with the standard angle, and the angle adjustment information thereof is transmitted by the drill holder rotation motor M. The information of the angle adjustment transmission is received from the second optical inspection machine 460, and the drill holder rotation motor M rotates the drill holder 130 to adjust the angle of the cutting end of the drill 10. When the angle of the drill 10 is adjusted, the regrind of the drill 10 is precisely performed by the re-grinding machine 400.

When the re-grinding of the drill bit 10 is completed, the control unit removes the downward force provided by the pull rod of the vertical cylinder 134a or controls the vertical cylinder 134a to rise to the original position. At this time, the elastic member 135b is lowered along with the lifting/lowering combination 133b, and the fixing screw 135a is in a compressed state in which it is pressed, and the downward force provided by the vertical cylinder 134a is removed or the vertical cylinder 134a is raised to the original position, and the lifting combination 133b Receiving rise from the above fixing screw 135a The force naturally rises.

As a result, the drill 10 is rotated upward, and returns to the original position, and is stably supported in a horizontal state. The drill bit 10 is stably supported in a horizontal state, and the rotary body 100 is rotated two times for the following process. Following the rotation of the rotating body 100, the convex buckle 134b of the lifting assembly 133b is moved along the space between the plurality of guiding plates 134c, and the guiding plate 134c is pulled away, and the chuck 131 and the drill bit 10 smoothly follow the subsequent process of the rotating table. When the rotating body 100 rotates the turntable 111 to the third rotational position, the reground drill 10 is also moved to the third rotational position following the turntable 111. The drill bit 10 moved to the third rotational position is washed according to the same process as the following process of the washing machine 500. First, as shown in Fig. 16, the cutting end of the drill bit 10 is inserted into the adhesive substance 510, and various foreign matters 10 adhering to the cutting end of the drill bit 10 are adhered to the adhesive substance 510 to be completely removed.

Next, the sink transfer unit 530 moves the washing tank 520 to the rear. As shown in Fig. 15, when the washing tank 520 is moved to the rear and the cutting end of the drill bit 10 is disengaged from the washing tank 520, the driving motor 540 is instantaneously operated, and as shown in Figs. 19 and 20, a certain amount of the washing tank 520 is turned toward Rotate the ball back and forth between either side. The rotating shaft 21 of the driving motor 540 is composed not on the same axis as the cutting end of the drill bit 10, so that the cutting end of the drill bit 10 is not repeatedly inserted at the same place as the adhesive substance 510.

Therefore, the washing operation is repeated a plurality of times, and the washing power is not reduced, so that the optimum washing function can be often performed. For the unillustrated symbol P, the cutting end insertion point of the drill bit 10 is used. The washed drill bit 10 is transferred to a subsequent process. On the other hand, in the case where the third optical inspection machine 550 is added, after the completion of the washing by the drill bit 10, and the normality is completed, the regrind is grasped as in the following continuous process.

That is, as shown in Fig. 17, the drill 10 is washed, and the slider 560 is an operation in which the slider segment 563 is moved in one direction. At the same time, the sliding segment block 563 is moved to one side, as shown in Fig. 18, and the third optical inspection machine 550 illumination 552 disposed on the side of the sliding segment block 563 is located in front of the washing-completed drill bit 10. In a state where the illumination 552 is on, the camera 551 is disposed in front of the illumination 552, and the cutting end of the drill 10 is photographed in front at the same position as the center of the cutting end.

The washing of the drill bit 10 and the inspection of the good or bad are completed, the turntable 111 of the rotating body 100 is rotated in the fourth rotational position, and the fourth rotational position is released from the drill holder 130 according to the drill bit 10 which is regrind by the drill unloading automatic device 700. After that, it is transported to the drill storage box B. At this time, the drill unloading automatic device 700 separates the good and the defective products, and transports them to the drill storage box B. In the case where the bit unloading robot 700 is provided with the positioning ring 13, the positioning ring adjuster 600 is provided at the fourth rotational position. In this case, the drill unloading robot 700 moves the drill 10 determined by the good product to the positioning ring adjuster 600, and the drill 10 judged by the defective product is directly carried to the defective drill storage box B. The drill bit 10 judged by the good product is a work turntable 610 in which the positioning ring adjuster 600 is mounted after the first unloading portion 710 of the drill unloading automatic device 700 is detached from the drill holder 130. At this time, the cutting end 11 of the drill bit 10 is a vertical device sandwiched by the drill insertion hole 611a toward the upper portion; in the same manner, if the drill 10 is mounted, the rotary table 610 is rotated in one stage.

If the turntable 610 is rotated in the first stage, the drill holder 611 is moved to the first position. At this time, the drill holder 611 is elastically separated from the upper portion of the turntable 610, so that the vertical position set at the first position is not disturbed. The bracket 623 is smoothly rotated.

As shown in FIG. 17, when the drill holder 611 is moved in the first position, the upper portion of the drill pusher 620 is vertically lowered from the drill holder 611. As a result, as shown in Fig. 18, the cutting end 11 of the drill 10 is inserted into the insertion recess 621a formed on the bottom surface of the drill pusher 620, and the body portion 12 of the drill 10 is in contact with the pressing end 621b of the drill pusher 620, and is turned down. mobile. At the same time, the positioning ring 13 that grips the body portion 12 of the drill bit 10 moves toward the cutting end 11 side of the body portion 12 of the drill bit 10. At this time, the bit push rod 620 sandwiches the positioning ring 13 of each of the drill bits 10 at different positions to move closer to the cutting end 11 side than the normal setting position. Then, in order to complete the setting process of the positioning ring 13, the positioning rings 13 are all moved while moving in the same direction.

On the other hand, according to the drill pusher 620, if the drill 10 is moved downward, the positioning ring 13 is pressed against the lower surface of the drill holder 611 while being in contact with the upper surface of the drill holder 611. During this process, the drill holder 611 is elastically supported, the elastic member 611d is compressed, and the horizontal direction of the drill bit 10 is rotated back and forth toward either side, and the lower portion of the vertical bracket 623 provided at the first position can be stably stabilized. The horizontal state is maintained; thus the drill bit 10 is stably lowered vertically.
