When drill bit loading robot 300 restores to origin-location, rotary body 100 rotates turntable 111 to the 2nd position of rotation.Therefore the drill bit 10 that, is installed on drill bit groove 130 is also along with turntable 111 moves to the 2nd position of rotation.By the machine 400 of refacing, realize refacing of drill bit 10 at the 2nd position of rotation.

Before realization is refaced, when preventing from refacing, cannot accurately complete the situation of refacing due to what be passed to from the machine 400 of refacing that the vibrations of drill bit 10 cause, by being disposed at the lift 150 in rotary body 100 fronts of the 2nd position of rotation, back-up block 151 is realized and being risen, thereby supports the cutting edge of drill bit 10.Now, collet chuck chuck 131 is by collet chuck chuck support unit 133, in stable maintenance level.

In the time that the upper end of back-up block 151 forms drill bit mounting groove 152, the cutting edge of above-mentioned drill bit 10 is installed on drill bit mounting groove 152, thereby in fastened state, double swerve can not occur.

In the time that the cutting edge of drill bit 10 passes through back-up block 151 by stable support, the 1st fluorescence detector 200 is measured the height of the cutting edge of drill bit 10.In the time that the external diameter of the cutting edge of drill bit 10 changes, the height of cutting edge all can change, and therefore the 1st fluorescence detector 200 is taken the cutting edge of drill bit 10, and its elevation information is passed to control part.

Receive the control part of elevation information, whether the height that judges cutting edge has gap with altitude datum, and after calculation correction distance, by controlling the action of lift 150, drill bit 10 is rotated up and down taking universal joint 132 as benchmark, thereby regulate the lip height of drill bit 10.

The detailed process of the lip height of adjustment drill bit 10 is as follows.

First control part makes the bar of vertical cylinder 134a decline.In the time that the bar of vertical cylinder 134a declines, owing to being the state that articulates projection 134b and be contained in guide card 134c of the fast 133b of lifting, the bar of vertical cylinder 134a declines along elevator 133b, its result collet chuck chuck 131 become can universal joint centered by the free state of rotation up and down.

And when the lip height of drill bit 10 is during higher than altitude datum, control part drives lift 150 to decline, and back-up block 151 is declined.Along with back-up block 151 declines, collet chuck chuck 131, due to self gravitation, is rotated down taking universal joint 132 as benchmark, its result as shown in Figure 9, the cutting edge of drill bit 10, to be installed on the state of drill bit mounting groove 152 of back-up block 151, declines along back-up block 151, thereby causes it highly to reduce.

If the lip height of drill bit 10 is during lower than altitude datum, control part drives lift 150 to decline, and makes back-up block 151 increase.Along with back-up block 151 rises, collet chuck chuck 131 can universal joint 132 for benchmark rotates up, as shown in figure 10, the lip height of drill bit 10 rises its result.

And, while further disposing lifting guiding element 153 on lift 150, when the lip height of drill bit 10 reaches behind reference position, when lifting guide card 153 declines, can cover the top of drill bit 10.Now, pressurization projection 153a pressurizes to the cutting edge top of drill bit 10.Drill bit 10 is stable holding state in drill bit mounting groove 152 thus, and the Shi Buhui that therefore refaces rocks, and can critically process.

And, detect the angle of the cutting edge of drill bit 10 by the 2nd fluorescence detector 460.The 2nd fluorescence detector 460 is taken the cutting edge of drill bit 10 in front, whether the angle that detects cutting edge is consistent with benchmark angle, and its angle correct information is sent to drill bit groove rotating motor M.From the drill bit groove rotating motor M of the 2nd fluorescence detector 460 receiving angle control informations, drill bit groove 130 is rotated, proofread and correct the angle of the cutting edge of drill bit 10.After the angle of drill bit 10 is corrected, refacing of the cutting edge of drill bit 10 will critically be carried out by the machine 400 of refacing.

Complete after the refacing of drill bit 10, should, by the control of control part, remove and provide to the decline power of the bar of vertical cylinder 134a, or make the bar of vertical cylinder 134a rise and restore extremely original position.Elastomeric element 135b now declines along elevator 133b, and the screw 135a that is fixed presses the state of compression, be removed or when the bar of vertical cylinder 134a rises and restores to original position when providing to the decline power of the bar of vertical cylinder 134a, elevator 133b receives the climbing power that above-mentioned elastomeric element 135b provides, and rises thereby realize naturally.Its result, drill bit 10 rotates up, and restores to original position, is stably supported with level.

When drill bit 10 is with level, while stably support, rotary body 100 rotates for carrying out next technique.Along with the rotation of rotary body 100, the projection 134b that articulates of elevator 133b moves along the clearance space between guide card 134c, causes guide card 134c to depart from, and collet chuck chuck 131 and drill bit 10 move to next technique with rotating disc.

When rotary body 100 rotates to the 2nd position of rotation by turntable 111, the drill bit 10 of refacing also follows turntable 111 to move to the 3rd position of rotation.

Move to the 3rd position of rotation drill bit 10, will be cleaned by washer 500, it specifically passes through following process.

First, as shown in figure 16, when the cutting edge of drill bit 10 is inserted into after adhesion substance 510, adhere to the various foreign substances 10 of the cutting edge of drill bit 10, bonded material 510 attaches, thereby is removed neatly.

Then, washing bucket transfer unit 530 is carried out the action that washing bucket 520 is transferred to rear.As shown in figure 15, when washing bucket moves to rear, the cutting edge of drill bit 10 is from washing bucket 520 spins off, and CD-ROM drive motor 540, by short-time duty, as shown in Figure 19 and Figure 20, carries out suitable rotation to washing bucket 520.Because the rotating shaft 21 of CD-ROM drive motor 540 is configured to not be positioned on same axis with the cutting edge of drill bit 10, therefore the cutting edge of drill bit 10 can not repeat to be inserted in the same point of adhesion substance.Therefore, even if carry out several times washing and cleaning operation, its cleansing power also can not reduce, and always can bring into play best cleaning performance.

The point that the cutting edge that undeclared symbol P is drill bit 10 inserts.

The drill bit 10 that cleaning completes is transferred to subsequent technique.

And, while further disposing the 3rd fluorescence detector 550, complete after the cleaning of drill bit 10, can grasp to reface by following continuous processing whether normally completing.

Under state as shown in figure 17, complete after the cleaning of drill bit 10, slider 560 makes slide block 563 move along a side direction.

As mentioned above, when slide block 563 is after a side shifting, as shown in figure 18, the illumination 552 that is disposed at the 3rd fluorescence detector 550 of the opposite side of slide block 563 will be positioned at the front of drill bit 10 of cleaning.Under this state, after irradiating illumination 552, the camera 551 that is disposed at the front of illumination 552 is taken the cutting edge of drill bit 10 in the front, position identical with the center of cutting edge.

The image information that above-mentioned camera 551 is taken is transferred into control part, and the image information of the normal cutting edge to pre-programmed and the image information receiving are compared analysis by control part, thereby judge good or bad.

While completing the cleaning of drill bit and quality testing, rotary body 100 rotates turntable 111 to the 4th position of rotation.At the 4th position of rotation, complete the drill bit of refacing and will unload robot 700 by drill bit and separate from drill bit groove 130, be carried to drill bit safe deposit box B.Now, non-defective unit and defective products will be distinguished by drill bit unloading robot 700, and be carried to drill bit safe deposit box B.

If when drill bit 10 disposes determining positions ring 13, will also dispose determining positions ring setting apparatus 600 on the 4th position of rotation.Now, drill bit unloading robot 700 only moves to determining positions ring setting apparatus 600 by the drill bit 10 that is judged to be non-defective unit, and the drill bit 10 that is judged to be defective products is directly carried to bad drill bit safe deposit box B.

Be judged to be the drill bit 10 of non-defective unit by unload the 1st unloading portion 710 of robot 700 by above-mentioned drill bit, from drill bit groove 130 separates, be installed on the workbench 610 of determining positions ring setting apparatus 600.

Now, drill bit 10 is sandwiched in drill bit folder hole 611a, and by right angle setting, thereby make cutting edge 11 upwards.As mentioned above, after drill bit 10 is mounted, turntable 610 carries out the 1st step rotation.

Turntable 610 occurs after the 1st step rotation, and drill bit groove 611 moves to the 1st position, now because drill bit groove 611 is from the flexiblely arranged spaced of top of turntable 610, therefore can not disturb with the vertical support frame 623 that is disposed at the 1st position, and it can rotate sleekly.

As shown in figure 17, when drill bit groove 611 moves to the 1st position, drill bit push rod 620 can decline from the upper vertical of drill bit groove 611.

As shown in figure 18, the cutting edge of drill bit 10 is inserted into the insertion groove 621a of the bottom surface that is formed at drill bit push rod 620 to its result, and the main part 12 of drill bit 10 is contacted by the press-side 621b of drill bit push rod 620, thereby is pushed downwards and moves down.Meanwhile, be sandwiched in the determining positions ring 13 of main part 12 of drill bit 10 along the main part 12 of drill bit 10, move to cutting edge 11 1 sides.Wherein, than normal desired location, above-mentioned drill bit push rod 620 makes the determining positions ring 13 of the difference that is sandwiched in each drill bit 10, more close to cutting edge 11 1 sides.This be for by after in the setting technique of the determining positions ring 13 that carries out, determining positions ring 13 all can be moved and realizes to same direction.

And after drill bit 10 moves down by drill bit push rod 620, determining positions ring 13 contacts above with drill bit groove 611, thereby can press drill bit groove 611 downwards.In this process, the elastomeric element 611d of resiliency supported drill bit groove 611 is compressed, and drill bit 10 returns to level, and the vertical support frame 623 that bottom is configured in the 1st position supports, thereby can stable maintenance level.Therefore, drill bit 10 can stably vertically decline.

And in the time that the downside of above-mentioned drill bit groove 611 disposes guider 220, above-mentioned guider 220 can wrap up the main part 12 of the drill bit 10 of decline, therefore above-mentioned drill bit 10 can not shake, thereby can more stably vertically decline.

The drill bit push rod 620 that drill bit 10 declines is restored to original position, and due to the elastic force of compressed elastomeric element 611d, drill bit groove 611 rises.Under this state, turntable 610 carries out the 2nd step rotation, and drill bit groove 611 rotates to the 2nd position.

As shown in figure 24, when drill bit groove 611 moves to the 2nd position, push rod 641 rises from the bottom of drill bit groove 611, as shown in figure 25, the lower end of the drill bit 10 that is installed on drill bit groove 611 is raised to certain altitude.Afterwards, determining positions ring push rod 642 starts vertically to decline step by step from the top of drill bit groove 611.In the time that determining positions ring push rod 642 starts vertical decline, the cutting edge 11 of drill bit 10 is inserted into the insertion groove 642a of the bottom surface that is formed at determining positions ring 13 push rods, simultaneously due to the lower end of drill bit 10 state in being supported by push rod 641, therefore determining positions ring 13 comes in contact with determining positions ring push rod 642, and is pushed downwards down.

As shown in figure 26, along with determining positions ring 13 moves down, the cutting edge 11 of drill bit 10 passes through insertion groove 642a, and enters to through hole 642b, and above-mentioned through hole 642b is communicated with the insertion groove 642a of the bottom of determining positions ring push rod 642.The cutting edge 11 of drill bit 10 enters to after through hole 642b, and in the time that determining positions ring push rod 642 periodically moves down, the 4th fluorescence detector 630 is taken the cutting edge 11 to the drill bit 10 exposing outside by above-mentioned through hole 642b.The positional information of the cutting edge of shooting 11 is sent to determining positions ring push rod 642 by the 4th fluorescence detector 630.

Along with determining positions ring push rod 642 periodically declines, the cutting edge of drill bit 10 is by the side point close to through hole 642b, wherein because the lower end from determining positions ring push rod 642 is identical to the distance h of the set point of determining positions ring 13 with the cutting edge 11 from drill bit 10 to the distance h of a side point of through hole 642b, therefore in the time that the cutting edge 11 of drill bit 10 is positioned on same level line with a side point of through hole 642b, determining positions ring 13 has also been located in set point.

As shown in Figure 26 and Figure 27, in the time that a side point of through hole 642b and the cutting edge 11 of drill bit 10 are positioned at same level line, the 4th fluorescence detector 630 is to determining positions ring push rod 642 delivering position information, and determining positions ring push rod 642 stops declining immediately.And determining positions ring push rod 642 and push rod 641 restore to original position.

When determining positions ring push rod 642 and push rod 642 restores to original position, due to the elastic force of the elastomeric element 611d of compression, the state of drill bit groove 611 to rise, makes turntable 610 carry out the 3rd step rotation, and makes drill bit groove 611 move to the 3rd position.

As shown in Figure 28 and Figure 29, drill bit groove 611 moves to behind the 3rd position, after the reversion robot 650 that is disposed at the 3rd position clamps drill bit 10, makes it increase, and after Rotate 180 °, is re-installed in drill bit groove 611.After drill bit 10 is reinstalled with the state of reversion, turntable 610 carries out the 4th step rotation, and drill bit groove 611 moves to the 4th position.

As shown in figure 30, when drill bit groove 611 moves to the 4th position, be disposed at the drill bit unloading unit 700 of the 4th position, the drill bit 10 that is installed on drill bit groove 611 with the state of reversion is lifted, it is transferred in ensuing subsequent technique from drill bit groove 611 separates.Now, because drill bit 10 is owing to reversing, the state that cutting edge is downward, therefore the cutting edge 11 of drill bit unloading robot 700 and drill bit 10 can not come in contact, and therefore can very safely drill bit 10 be transferred to subsequent technique.

As mentioned above, through a series of process, determining positions ring 13 is automatically set, and due to always constant to the distance of cutting edge and determining positions ring 13, therefore drill bit 10 can be installed on the certain position that adds work drilling machine all the time.Therefore, be formed at the through hole of printed circuit board (PCB), always with certain degree of depth, critically processed.

Meanwhile, due to the sustainable rotation of turntable 610, therefore above-mentioned setting operation is carried out serially.

And completing place determines the drill bit 10 of the setting of ring 13, the 2nd unloading portion 720 that unloads robot 700 by drill bit, from operation post 610 separates, is transferred to drill bit safe deposit box B.

The present invention's a succession of process as above repeatedly, thus carry out serially refacing of drill bit 10.

Although with reference to accompanying drawing, the preferred embodiments of the present invention have been described in detail in detail, but the present invention do not limit by the above embodiments, those skilled in the art can not depart under the prerequisite of thought of the present invention, can carry out various deformation, and this distortion all belongs to interest field of the present invention.
