The automatic installation apparatus of embodiment as shown in Fig. 3 A also comprises: draw and attitude is confirmed device 50, be used to confirm that the circuit chip element is mounted 10 and draws and this circuit element is mounted 10 with correct position or attitude absorption; One standard type circuit element tumbler 60 is used for changing it when the poor direction of standard type circuit chip element is true; One special type circuit element tumbler 70 is used for changing it when the poor direction of special type circuit chip element is true; One circuit element is confirmed device 80 again, is used for confirming the absorption of circuit chip element again; These devices are successively set on the circuit element of band conveyer 30 fronts and X-Y platform 40 posterior mid-line are installed.Draw and attitude confirms that device 50 is used to confirm that the circuit chip element is mounted absorption and this circuit element of 10 and is mounted 10 attitude of drawing, for example be mounted the vertical direction of electrode of the circuit element of head absorption.Absorption and attitude confirm that device 50 can comprise a photoelectric tube or similar device. Circuit element tumbler 60 and 70 is respectively applied for correcting mark pseudotype and depends on the installation direction of the special type circuit element of circuit component types, and is used for changing it when the malposition of the circuit chip element of being drawn by the ozzle head.Circuit element confirm again the effect of device 80 are testing circuit elements by during the circuit element tumbler 60 and 70 from the whereabouts of installation head 10.In illustrated embodiment, circuit element confirms that again the structure of device 80 is roughly identical with attitude affirmation device 50 with absorption.In addition, automatic installation apparatus also comprises: a suction release pin device 90 is used for when installation head 10 is installed on the substrate split circuit element on the installation head 10 to circuit element; One direction recovery device 100 is used to make the special type circuit element towards incorrect direction to return to correct direction; One puts down device 110, is used to put down the circuit element that is successively set on X-Y platform 40 circuit element of posterior mid-line is installed; These devices 50～110 are arranged on below the movable passageway of installation head 10.
The automatic installation apparatus of the illustrated embodiment of Gou Chenging is operated so as mentioned above: installation head 10 is drawn the circuit chip element from most band conveyers 30 in succession, rotation along with rotating disk 20, the circuit element of drawing is transported to device 50,60,70 and 80, to carry out various checks, then, installation head 10 moves down, and beginning access system in order is that the circuit element of a begins at the substrate that is being used for printed circuit board (PCB) circuit element by check to be installed from number.Otherwise, when device 50 detects the absorption fault of circuit element or circuit element when being drawn with incorrect direction or attitude, failing to draw the installation head of circuit element just can not install mobile, and can not drop to the circuit element installation site of the substrate that is arranged on the X-Y platform 40 with the installation head that incorrect direction has been drawn circuit element, therefore just can not be installed to circuit element on the substrate.As an alternative, rotating disk 20 controlled another installation head that are arranged on this installation head back that make pick up a same circuit element and be installed on the substrate.For example, when detecting the mark number is that an installation head place (it is the circuit chip element of d that this installation head has been drawn number) of 4 is when occurring drawing fault or incorrect attitude, the mark number is that to draw numbers from band conveyer 30 be the circuit element of d for 24 installation head, rotating disk 20 promptly rotates, so that the mark number is 24 installation head can be carried out circuit element d on substrate a fitting operation, as shown in Fig. 3 B.In addition, suppose that detecting 60 labels in the installation head is that fault or incorrect attitude appear drawing in 58 installation head, this is just before rotating disk 20 is finished week rotation, thereby the installation head of the label of the relation mark between the with good grounds circuit element kind that will install of select tape and the installation head of the having finished fitting operation operation of drawing circuit element, and rotating disk 20 promptly rotates, so that this installation head can be carried out the fitting operation of circuit element on substrate.In illustrated embodiment, the control of this operation is to realize that by the drive motors 23 of rotary encoder control rotating disk 20 installation head 10 is carried out the circuit element fitting operation according to the random access system beyond the sequential access system.In this embodiment, drive motors 23 is suitable for and changes rotary speed at leisure, so that during the velocity variations of rotating disk 20, inertia can not influence installation head circuit element is installed.When the installation head of the circuit element of having drawn incorrect attitude by rotating disk 20 when the direction of rotation of rotating disk 20 moves, direction recovery device 100 makes the circuit element on the tip that is fixed on installation head 10 recover direction, at circuit element is under the situation of special type, installation head has been drawn circuit element in described mode hereinafter from band conveyer 30, then, no matter be standard type or special type, put down device 110 all separates and put down incorrect attitude from the ozzle head of installation head 10 circuit element.In putting down device 110, the circuit element that separates incorrect attitude from installation head 10 is to finish by the promotion of suction release pin device 120.
The driving mechanism that is used for installation head can comprise: for example, be assemblied in the electromagnetically operated valve that cylinder and being used on each installation head is realized the driving and the control of cylinder.But, adopt the driving mechanism of this cylinder and electromagnetically operated valve combination to need a large amount of parts, thereby manufacturing cost increased.This driving mechanism also has another shortcoming: because cylinder usually leaks gas and make the actuating speed of mechanism slack-off, so can not accurately finish needed action.
In view of the above, actuating force transmission mechanism in illustrated embodiment constitutes like this: the capitate armature spiral piping arrangement that moves with the signal of telecommunication is set, so that the power that drive source produces can be sent to driven-mechanism by the pin that stretches out because of the action of capitate armature spiral piping arrangement between the drive source of equipment and driven-mechanism.
The actuating force transmission mechanism of this structure in the illustrated embodiment is easy to the low cost manufacturing, because only actually needs capitate armature spiral piping arrangement.This actuating force transmission mechanism also has another advantage: can be accurately and drive driven-mechanism reliably, because faults such as gas leakage will never take place capitate armature spiral piping arrangement, and it can promptly respond.
Describe the actuating force transmission mechanism in detail with reference to Fig. 4 A and 4B below.
Fig. 4 A mainly represents an actuating force transmission device, under the situation of its sd so: installation head 10 moves down, so that a chip belt T who carries from band conveyer 30 by suction takes out a circuit chip element, installation head 10 moves down with respect to circuit element tumbler 60, so that circuit element is towards correct direction; Installation head 10 moves down, so that this circuit element is installed in a substrate P that is used for a printed circuit board (PCB).This actuating force transmission mechanism is installed in the automatic installation apparatus and comprises capitate solenoid 130,131 and 132, so that make installation head 10 by carrying out needed move as drive source drives motor 133, with in the installation that is used for finishing on the substrate P of printed circuit board (PCB) circuit element.It is to realize that by capitate armature solenoid 130,131 and 132 power of drive motors 133 is sent to each driven-mechanism by these capitate armature solenoids that these of installation head 10 move down.Driven-mechanism comprises joggle piece 134 and 135, they mesh with solenoid pin 130a and 131a respectively, the manner of execution of 130a and 131a is to stretch out from capitate armature solenoid 130 and 131, just at parts 134,135 and pin 130a, when 131a is meshing with each other, driven-mechanism just moves down installation head 10.The actuating force that produces as public drive source drives motor 133 is sent to driven-mechanism by the rotating shaft 137,138 and 139 that links to each other with drive motors 133.Represent drive motors of this equipment and the connection between the driven-mechanism with chain-dotted line among Fig. 4 A.Cam disc 140 and 141 and 142 and 143 are housed respectively on the rotating shaft 137 and 139.Cam disc 140 to 142 is connected respectively to drive rod 148,149 and 150 by cam follower 144,145 and 146, and drive rod 148,149 and 150 lower end are installed in respectively on capitate armature solenoid 130,131 and 132.

Circuit element transmission device 60,70 and direction recovery device 100 preferably comprise a clamp system separately, and this clamp system is made of the jaw that is arranged on all directions, clamp circuit element equably from all directions.
Is that example is described this clamp system below with reference to Figure 13 to 18 with circuit element tumbler 60.
Clamp system comprises: a bellmouth 402 that has a groove; Pass this bellmouth 402 and insert, vertically moving joystick 403 and 90 ° of degree angles four jaw 401a～401d being arranged in the bellmouth 402, protruding upward from bellmouth at interval.Bellmouth 402 is a disk shape, within it on the circumference whole form four certain intervals and certain width help shape guide 404a～404d.Guide 404a～404d is used to guide the vertical moving of joystick 403, and for this purpose, this guide is assemblied among the otch 406a～406d of lower flange 405 of joystick 403.Joystick 403 also is equipped with a upper flange 407 than minor diameter that separates with lower flange 405.Upper flange 407 is also processing four otch 408a～408d with the corresponding position of lower flange 406a-406d.Otch 408a～408d is used for supporting in the following manner jaw 401a～401d.Jaw 401a～401d be processed into be roughly L shaped so that its tip can clamp a circuit chip element mutually jointly.The outside of each jaw processes an outer lug, and shown in 409a or 409b, the engagement of the upper periphery of this outer lug and bellmouth 402 or (in the illustrated embodiment), the guide 404a～404d with bellmouth 402 meshed; The inboard of each jaw processes an internal projection, shown in 410a or 410b, and the engagement of the lower surface of the upper flange 407 of this internal projection and joystick 403.Internal projection 410a and 410b are fulcrum at jaw 401a～401d duration of work as the strong point.The lower surface of the immediate upper flange 407 of this internal projection processes the oblique angle between 10 °～15 °, so that this internal projection can be around this lower surface engagement in rotation.The outer lug of jaw is supported on the guide plate 404a～404d of bellmouth 402, jaw 401a～401d is positioned in the bellmouth 402, upper flange 407 engagement of the internal projection of jaw and joystick 403, jaw are partly packed in otch 408a～408 of upper flange 407, and the point upward of jaw stretches out.Jaw 401a～401d extends downwards from its outer lug in the outside separately, in the bellmouth 402 of packing into and have an arc-shaped notch, shown in 411a among Figure 13 or 411b.This recess is used to hold a garter spring 412, to support jaw 401a～401d reliably around joystick 403.
In the clamp system of said structure, shown in Figure 13 to 16, when joystick 403 is return down, when lower flange 405 drops to the inner bottom surface of bellmouth 402, the outer lug 409a of jaw 401a～401d and 409d are near the top of bellmouth 402, helical spring 412 is expansion around the engagement in rotation place between the lower surface of the internal projection 410a of jaw and 410b and upper flange 407, so that the tip of jaw is approaching mutually, makes jaw be in closure state (Figure 13).Then, when driving joystick 403 when bellmouth 402 stretches out, the jaw 401a～401d that is supported on around the joystick 403 moves up, thereby the outer lug 409a of jaw and 409b break away from the positively engaging with bellmouth 402 tops.At this moment, the helical spring 412 of expansion shrinks.Jaw 401a～401d can outwards be moved around rotating meshing point under the effect of the power of helical spring 412 synchronously, the tip of jaw is opened together (Figure 16).This can be contained in by in the determined space of open jaw circuit element.Then, the outer lug 409a that the moving down of joystick 403 makes jaw and the top of 409b and bellmouth 402 are close to or mesh, and with closed jaw, clamp circuit element reliably, and bellmouth 402 is owing to the bias voltage of following spring is positioned at high slightly position.
The mode of the clamp system of this structure shown in can Figure 17 is contained in the circuit element tumbler 60.In circuit element tumbler 60, the upper end of pipe 414 in bellmouth 402 integrally is contained in.Interior pipe 414 support assemblies are in outer tube 413, and pipe 414 inserted in joystick 403 passed.The bias voltage that interior pipe 414 is made progress by the compression spring 415 between pipe 414 and the outer tube 413 in placing, therefore interior pipe 414 can move up slightly with the rising of joystick 403.In addition, joystick 403 is also by the downward in addition bias voltage of the tension force of compression spring 418, and compression spring 418 places between the axle collar 417 of the axle collar 416 that is installed in joystick 403 lower ends and outer tube 413.Moving up of joystick 403 realizes that by forming whole moving up of plate 419 with the axle collar 416 plate 419 moves up by the driving cam 158 that is assemblied on the rotating shaft 138, and rotating shaft 158 links to each other with drive motors 133, as shown in Fig. 4 A.
As mentioned above, in circuit element tumbler 60, when upwards promotion forms whole plate 419 with the axle collar 416, joystick 403 moves up, thereby the outer lug of jaw 401a～401d breaks away from and the engagement of bellmouth 402, helical spring 412 is shunk to open jaw, be enough to hold the space that is fixed on a circuit element on the installation head 10 thereby form.Along with moving up of joystick 403, interior pipe 414 is because the tension force of compression spring 415 is elevated to a precalculated position.Then, when circuit element is included the most advanced and sophisticated determined space of jaw 401a～401d in, plate 419 descends, joystick 403 is moved down, the effect that the outer lug of jaw leans against owing to compression spring 415 is in the top of the bellmouth 402 of high position slightly, thereby jaw 401a～401d tightens helical spring 412, makes the most advanced and sophisticated circuit element that clamps of jaw.When jaw 401a～401d clamps this circuit element, stepping motor 420 among Fig. 4 A makes circuit element tumbler 60 rotations one suitable angle, make this circuit element towards correct direction location, jaw 401a～401d is closed under the effect of helical spring 412 simultaneously, makes circuit element centering.
Certainly, this clamp system also can be used for installation head.
From above as can be seen, this clamp system can be handled accurate clamping and the centering that jaw is realized a circuit element simultaneously.
Now, how describe this clamp system with reference to Figure 19 to 24 is contained on the circuit element tumbler 70.
As mentioned above, around 60, four jaws of the circuit element tumbler that is used for the standard type circuit element are arranged in joystick 403.But this structure is not suitable for the circuit element tumbler 70 of special type circuit element, because the special type circuit element than the weight of standard type therefore, the clamp system that is used for special type circuit element rotating mechanism 70 preferably includes and is contained in the ozzle head that helps installation head on the installation head 10 and draws a pair of jaw of circuit element and be contained on the circuit element tumbler 70 another to jaw.
Especially, this clamp system comprises and being contained on the installation head 10 so that a circuit element is clipped in a pair of jaw 501a and 501b therebetween and is contained on the circuit element tumbler 70 another to jaw 502a and 502b.The jaw 501a of installation head 10 and 501b are in installation head 10 opening and closing and this circuit element is installed to the substrate P that is used for a printed circuit board (PCB) when band conveyer 30 takes out a circuit element, and the jaw 502a and 502b jaw 501a and the 501b with installation head 10 during the direction of adjusting circuit element that are contained on the transfer 70 clamp this circuit element spare from all directions.
Hereinafter jaw 501a, 501b, 502a and the 502b mounting means with respect to circuit element tumbler 70 is described with reference to Figure 20 and 21.
A pair of jaw 502a and 502b are arranged in the spill bellmouth 503 around a joystick 504, insert but joystick 504 passes the vertical moving ground, center of bellmouth 503.Bellmouth 503 is a disk shape, integrally has the rib shape guide 505a and the 505b of two certain widths on its inner periphery.Guide 505a and 505b play the vertical moving of guiding joystick 504.For this purpose, guide 505a and 505b are laid respectively among the otch 507a and 507b that processes on the lower flange 506 of joystick 504.Joystick 504 also has a upper flange 508, and its diameter separates less than lower flange 506 and with lower flange 506.Upper flange 508 is processing otch 509a and 509b with otch 507a and the corresponding position of 507b, and jaw 502a and 502b partly are contained among otch 509a and the 509b respectively.It is L shaped that jaw 502a and 502b roughly are.The outside of jaw 502a and 502b has outer lug 510a and 510b respectively, the top engagement of this outer lug and bellmouth 503; The inboard of jaw 502a and 502b has internal projection 511a and 511b respectively, the lower surface engagement of they and upper flange 508.Internal projection 511a and 511b are as the strong point or the fulcrum of the clamp operation of jaw.The lower surface of upper flange 508 10 °～15 ° angles that outwards are inclined upwardly, make each internal projection 511a and 511b the tip can with its engagement in rotation.In illustrated embodiment, the guide 505a of the outer lug 510a of jaw 502a and 502b and 510b and bellmouth 503 and 505b engagement, the lower surface engagement of the upper flange 508 of internal projection 511a and 511b and joystick 504, jaw 502a and 502b are positioned partially among the otch 509a and 509b of upper flange 508; Therefore the tip of each jaw 502a and 502b can protrude upward.Pack into the position of bellmouth 503, the outside of jaw 502a and 502b processes arc incision 512a and 512b, and a garter spring 513 is contained in this arc incision, and jaw can be supported on around the joystick 504 reliably.Shown in Figure 20 and 22, in the clamp system of this structure, when joystick 504 returns to when being enough to make lower flange 506 with height that the inner bottom surface of bellmouth 503 contacts, the top engagement of the outer lug 510a of jaw 502a and 502b and 510b and bellmouth 503, because the meshing point expansion of jaw bottom between the lower surface of internal projection 511a and 511b and upper flange 508, make helical spring 513 expansions, thereby jaw 502a and 502b most advanced and sophisticated closed (Figure 20).Then, joystick is subjected to drive and stretches out from bellmouth 503, and jaw 502a and 502b move up with moving of joystick 504, so that the outer lug 510a of jaw 502a and 502b and 510b can break away from the positively engaging with the top of bellmouth 503.At this moment, the helical spring of expansion 513 shrinks, and makes jaw 502a and the 502b rotation of the meshing point between internal projection 511a and 511b and upper flange 508 simultaneously, opening the jaw tip, thereby determines to be enough to hold the space (Figure 22) of a circuit element.Then, when circuit element is included this space in, outer lug 510a that the moving down of joystick 504 makes jaw and 510b are near the top (bellmouth 503 is owing to the bias voltage of a compression spring moves to high position slightly) of bellmouth 503, so that jaw is most advanced and sophisticated closed, clamp circuit element reliably.
As shown in Figure 19, installation head 10 equally also is equipped with a pair of jaw 501a and 501b; The vacuum nozzle 10a of installation head 10 is as joystick, and jaw is provided with down, extends downwards from the ozzle head of installation head 10.As mentioned above, installation head 10 is a drive source with drive motors 133, the vertical moving vacuum nozzle.In order to draw circuit element, when capitate armature solenoid 130 receives a control signal that makes 134 engagements of solenoid 130a and joggle piece, as shown in Figure 23, working shaft 148 moves down by the Cam Follower 144 that the cam path with cam disc 140 meshes, the capitate armature solenoid 130 that is contained on the axle 148 is moved down, thereby the vacuum nozzle of installation head 10 is descended.The decline of installation head 10 makes it can lean on suction to take out a circuit element from the chip belt of band conveyer 30, and then, when leaning on a pair of jaw 501a and 501b to clamp circuit element, vacuum nozzle rises to the home position along the cam path of camshaft 140.When being installed to this circuit element on the substrate P, capitate armature solenoid 132 discharges fixed lever 136, and the vacuum nozzle of installation head 10 is descended.Open at the tip of jaw 501a and 501b.These operations are to carry out when moving to a precalculated position in the rotation of installation head 10 solid rotating disks 20, during this period, circuit element not only is mounted an ozzle head of 10 and holds, and clamped, so this clamp system clamping and transmit the special type circuit element that overweights the standard type circuit element effectively by a pair of jaw 501a and 501b.
In addition, as shown in Figure 24, in circuit element tumbler 70, the top of pipe 515 in bellmouth 503 integrally is contained in, interior pipe 515 is inserted in the outer tube 514, and pipe 515 inserted in joystick 504 passed.The bias voltage that interior pipe 515 is made progress by the compression spring 516 that places between outer tube 514 and the interior pipe 515, therefore interior pipe 515 can move up with the rising of joystick 504.Circuit element tumbler 70 also comprises the lower end that the compression spring 519 that is arranged between the axle collar 517 and the axle collar 518 and a plate 520 axle collars 517 are installed in joystick 504, the axle collar 518 is contained in the lower end of outer tube 514, and plate 520 and the axle collar 517 form whole and by the in addition downward bias voltage of compression spring 519.The cam 158 that plate 520 is mounted on the rotating shaft 138 that links to each other with drive motors moves up, so that joystick moves up.This makes the top of the outer lug 510a of jaw 502a and 502b and 510b and bellmouth 503 break away from engagement, thus the upper end of jaw owing to the contraction of helical spring 513 is opened, formation is enough to hold the space that is fixed on the circuit element on the installation head.Along with moving up of joystick 504, the expansion of interior pipe 515 depended on pressure springs 516 and rise to a predetermined altitude.Then, when circuit element is included between jaw 502a and the open tip of 502b, joystick 504 is owing to the decline of plate 520 moves down, make the outer lug 510a of jaw 502a and 502b and 510b top near bellmouth 503, bellmouth 503 is owing to the effect of the power of compression spring 516 is in high slightly position, thereby jaw 502a and the expansible helical spring 513 of 502b, make the jaw tip can clamp circuit element jointly.Like this, jaw 502a and 502b fix this circuit element in all its bearings reliably with jaw 501a and 501b.Further, circuit element tumbler 70 is with installation head 10, by stepping motor 521 rotations one suitable angle, the position of correcting circuit element and centering, turn to and can carry out like this: installation head 10 moves down, open jaw 501a and 501b, the jaw 502a of circuit element tumbler 70 and 502b are clamped by suction be fixed on circuit element on the ozzle head of installation head 10.This can not produce any problem, because installation head 10 clamps this circuit element during moving up.
In addition, in illustrated embodiment, as mentioned above, when putting down device 110 and put down the special type circuit element of the incorrect attitude that clamps by installation head with above-mentioned clamp system, suction release pin device 120 is driven from installing 10 separates the circuit element of this incorrect attitude, release pin 120 should be near the jaw 510a and the 510b of the circuit element of the incorrect attitude of common clamping, in case this element drops from installation head 10.For fear of this trouble, a direction recovery device 100 is housed, so that the circuit element that is clamped by jaw 501a and 501b returns to the direction of the action that does not stop suction release pin 120 or picks up the direction of circuit element from band conveyer 30.For this purpose, direction recovery device 100 is equipped with a pair of as the jaw in the circuit element tumbler 70.
From the above as can be seen, in the clamp system that circuit element tumbler 70 is adopted, be contained on the installation head 10 corresponding jaw to circuit element tumbler 70 mutual synchronization actions, thereby can finish the transmission of the special type circuit element that overweights the standard type circuit element effectively and turn to.
