Abstract
The invention provides an electronic component installing device, which can relieve the distance transmission operations when a worker is performing head search of an electronic component supply device and further prevent a component taking failure so as to keep the adsorption rate. A bag is identified and a CPU (16) determines the identification result. When the distance (deviation) between the bag (47) and the absorption position is beyond a determined distance and satisfies the maintenance condition of the distance transmission during an identification result checking process, the CPU (16) outputs a minimum distance transmission signal to an absorption target component supply unit (13) which then transmits a tape in the minimum space and automatically performs maintenance of distance transmission.

By above structure, the below action of explanation electronic element installation device.
If printed circuit board (PCB) P accepts and is present in the supply department of Handling device 2 from upstream side device (not shown), then the printed circuit board (PCB) P in the supply department is moved to the location division, and carry out the located and fixed of this printed circuit board (PCB) P in in-plane and above-below direction.
Then, if printed circuit board (PCB) P is positioned, then inboard arm 7 is by the driving of Y direction linear electric machine 9, thereby slide block slides along the guide rod that extends forwards, backwards and moves to the Y direction, and by directions X linear electric machine 23, installation head 10 moves to directions X, moves to the element extracting position top of element feeding unit 13, reduce adsorption mouth 101 by the driving of spindle motor up and down, thereby take out electronic components from element feeding unit 13.At this moment, installation head 10 is moved and makes its rotation to directions X, and then make adsorption mouth 101 liftings, thereby a plurality of adsorption mouth 101 can be taken out electronic component from element feeding unit 13.In addition, with the arm 7 of inboard similarly, the arm 8 of front side is by the driving of Y direction linear electric machine, move to the Y direction along the guide rod that extends forwards, backwards, and by the directions X linear electric machine, installation head 11 moves to directions X, moves to the element extracting position top of element feeding unit 13, reduce adsorption mouth 111 by the driving of spindle motor up and down, thereby take out electronic components from element feeding unit 13.At this moment, installation head 11 is moved and makes its rotation to directions X, and then make adsorption mouth 111 liftings, thereby a plurality of adsorption mouth 111 can be taken out electronic component from element feeding unit 13.
Promptly, at first, for example adsorption step according to installation data, by the installation head 10 that in the arm 7 of inboard, is provided with, take out 4 electronic components in turn from the element feeding unit 13 of element supply device 5, installation head 11 by being provided with in the arm 8 of front side simultaneously takes out 4 electronic components in turn from the element feeding unit 13 of element supply device 3.Promptly, 4 adsorption mouth 101 of the installation head 10 that is provided with in the arm 7 of inboard are taken out electronic component in turn from element feeding unit 13,4 adsorption mouth 111 of the installation head 11 that is provided with in the arm 8 of front side are taken out electronic component from element feeding unit 13 simultaneously, thus and thus, installation head 10,11 separately is according to the absorption of the step of correspondence and take out 4 electronic components.At this moment, based on the beginning of the element absorption of the installation head 11 of front side with based on the beginning of the element absorption of the installation head 10 of inboard, finish based on the absorption of all elements of the installation head 11 of front side in addition and finish also can stagger sometimes based on the absorption of all elements of the installation head 10 of inboard.
In addition, after this takes out, the adsorption mouth 101,111 of two installation head 10,11 that raise, make installation head 10,11 by component recognition video camera 15 tops, unified 4 electronic components separately of taking by 4 adsorption mouth, 101, the 111 adsorbed maintenances of two installation head 10,11 in this moves, thus 27 pairs of these images that photograph of recognition process unit are discerned the offset of processing grasp electronic component with respect to each adsorption mouth 101,111.
Then, set board recognition camera 8 in the installation head 10,11 of two arms 7,8 is moved to each printed circuit board (PCB) P top, thereby take appended positioning mark on the printed circuit board (PCB) P of location on the Handling device 2, thereby and discern by 27 pairs of these images that photograph of recognition process unit and to handle the position of grasping each printed circuit board (PCB) P.Then, in the installation coordinate of installation data, consider location recognition result and each the component recognition result of each printed circuit board (PCB) P, thereby each adsorption mouth 101,111 correction position skew on one side is Yi Bian be installed to electronic component on each printed circuit board (PCB) P respectively.
As mentioned above, when electronic component being installed on the printed circuit board (PCB) P, in when, in the element feeding unit 13 of element supply device 3 element having taken place and having used up, thereby CPU16 work shows the situation that element is used up that taken place in monitor 20,201, and, the display unit of the not shown display lamp that is provided with in electronic element installation device 1 etc. is neglected and is brightly gone out suddenly, reports to the operating personnel.In addition, CPU16 work, the motor of Y direction linear electric machine 9,99, directions X linear electric machine 23,223 etc. stops, and the installation and operation of electronic component stops.Then, prepare button 51 if the operating personnel presses the element feeding unit of monitor 20 or monitor 201, the luminous element 71 that then displays a light can be turned off the light, and the element feeding unit is prepared button 51 and turned off the light.In addition, can change element feeding unit 13, the operating personnel changes, and the element feeding unit 13 that element is used up has taken place.
After changing the end of job, at first, prepare button 51 if the operating personnel presses the element feeding unit, then luminous element 71 can bright lamp, and the element feeding unit is prepared button 51 bright lamps.Then, if the operating personnel presses start button 53, then the installation and operation of electronic component begins.
Below, seek the head action based on the flowchart text of Fig. 4 automatically after having changed element feeding unit 13 and from the electronic component that carries out before the action that element feeding unit 13 takes out electronic components begins.
In CPU16, before carrying out taking out the action of electronic components from element feeding unit 13 absorption, for absorption object the element feeding unit (below, be called absorption object elements feeding unit) 13, for example the recognition data of putting down in writing by the database data of storing in RAM17 corresponding with the kind of band of whether can carrying out judges that whether can carry out bag discerns.Then, such as mentioned above, absorption object elements feeding unit 13 be not before set (set), but change the new element feeding unit of installing 13 in back, and it is such shown in Fig. 5 (a), the width with 46 of having taken in the element of these element feeding unit 13 supplies is 8mm, when being 4mm (interval between all adjacent bags is that spacing is 4mm) as the spacing of each bag 47 of the incorporating section of element, for example, CPU16 is judged as and can carries out bag identification based on the feed appliance number (sequence number) that the control device 13S that is provided with from absorption object elements feeding unit 13 sends.In addition, be provided with transfer port 49 in 46 being with of Fig. 6, its transmission motor 13M by band is driven in rotation, and with cooperates at the tooth that periphery set that is used for the sprocket wheel that rotating band transmits, the interval of all adjacent transfer ports 49 be configured to and the adjacent tooth of sprocket wheel between interval identical distance (being 4mm under the situation of Fig. 6).
The result, the signal that CPU16 transmits the absorption object elements feeding unit 13 output spacings of object, absorption object elements feeding unit 13 will band transmit as a spacing (for example 4mm) that specifies Spacing, promptly with take in electronic component bag the suitable distance (step S1) in interval.If the release that this band transmits, then CPU16 is chosen in the board recognition camera 14,14 that is provided with in installation head 10 or 11 near the board recognition camera 14 of adsorbing object elements feeding unit 13 based on the position of absorption object elements feeding unit 13 and installation head 10,11.Then, follow moving of installation head 10 or 11, selected board recognition camera 14 moves to the pressing plate that is provided with in absorption object elements feeding unit 13 be the top (step S2) that inhibitor (suppressor) goes up the element conveying end that forms.
Then, carry out bag identification (step S3).That is, the board recognition camera 14 of top that has arrived the element conveying end via element conveying end 45 near the capturing element absorption position with 46 bag 47.Then, recognition process unit 27 obtains as shown in Figure 5 element conveying end 45, with 46 and the image of bag 47, carries out image processing.Processing result image is sent to CPU16, and CPU16 carries out the judgement (step S4) of recognition result.In the judgement of this recognition result, CPU16 judge the position of bag 47 and the distance between the absorption position (skew) whether be the judgement distance that preestablishes and in RAM, store, for example less than the value of minimum spacing (although in that to be set at the possibility that the above time interval of minimum spacing is offset higher, but can't carry out spacing offset correction described later, therefore be preferably value less than minimum spacing) 1.5mm more than, promptly judge whether to satisfy the repairing condition that spacing transmits.
Then, position and the distance between the absorption position at bag 47 are to judge more than the distance, when satisfying repairing condition, the signal that CPU16 transmits absorption object elements feeding unit 13 output minimum spacings, absorption object elements feeding unit 13 is with for example 2mm (with reference to Fig. 5) of the minimum spacing that preestablishes and store in RAM, the interval (equating with the interval of the adjacent tooth of sprocket wheel described later) of promptly taking in the bag of electronic component is when being 4mm, less than the spacing of this spacing and be that the spacing of bag is come conveyer belt (step S6) divided by the value of integer gained (at this moment being the 2mm of 1/2 spacing).
Here, minimum spacing, it is each type (feed appliance number) by element feeding unit 13 and setting, be taken in the electronic component that this element feeding unit supplied band bag spacing, be about to common band and transmit spacing and (be not limited to above-mentioned 2 divided by integer as described above, it can be for example 4 or 6 etc. the integer more than 2, get final product less than setting spacing) value of gained, or the element feeding unit can with the spacing of minimum of indexing transfer.Perhaps, should may not be minimum spacing divided by the spacing of integer gained.Perhaps, also can not to set the spacing of spacing divided by the integer gained, but with less than setting spacing and will setting spacing and transmit divided by the spacing of the integral multiple of the minimum spacing in this feed appliance of integer gained.Element feeding unit 13 can transmit the band (having disposed the bag that is used for receiver member with this spacing) of a plurality of kinds that should transmit with the spacing of minimum spacing or its integral multiple.Therefore, use if after using the band of minimum spacing, load onto the bigger band of spacing, then according to the position of the sprocket wheel of the band that in element feeding unit 13, is provided with and has transmitted at last minimum spacing, the position of absorption position and bag does not match, even after this transmitting skew still with the spacing of this regulation yet.At this moment if transmit band several times with minimum spacing at least, then collecting bag can be consistent with absorption position.When the band of the twice of using minimum spacing, if skew is arranged, then transmission once just can be in normal position.
And then, the transmission of common band be set at interval sprocket wheel adjacent tooth the interval (promptly, the interval shown in Fig. 5 (a) and (b) for example) or with its distance (1/2 or 1/4 etc.) divided by the integer gained with 46 transfer port 49, the perhaps distance of its integral multiple, the spacing that can transmit at this element feeding unit 13 has (the transmission spacing of the band of a plurality of kinds that can transmit is not simultaneously) when a plurality of, minimum spacing can be made as spacing minimum in these a plurality of spacings.And then, so long as integer/one at the interval of the adjacent tooth of these sprocket wheels or the spacing of integral multiple, be integer/one who wants the common transmission spacing of the band that transmits, then also the spacing that may not be the spacing of this element feeding unit 13 minimum that can transmit can be made as the transmission spacing that is used to repair.
In addition, when CPU16 has carried out the judgement of recognition result, in the distance of the position of bag 47 and absorption position less than judging distance, and when not satisfying repairing condition, absorption, the taking-up action (step S8) of electronic component carried out in CPU16 work, adsorption mouth via element conveying end 45.In addition, monitor 20,201 for example is shown as " spacing transmits normal ".
In addition, carried out the band transmission with the spacing of minimum after, CPU16 waits for that band transmits end and finishes (step S7), if band transmits and finishes, then signals are taken in CPU16 board recognition camera 14 outputs that the last time has been taken bag 47, carry out bag identification (secondary bag of identification) (step S3) once more.That is, as mentioned above, board recognition camera 14 is taken the bag of band via the element conveying end, and recognition process unit 27 obtains element conveying end 45 such shown in Fig. 5 (b), with 46 and the image of bag 47, carries out image processing.Processing result image is sent to CPU16, and CPU16 carries out the judgement (step S4) of recognition result.In the judgement of this recognition result, such shown in Fig. 5 (b), the position of bag 47 is consistent with absorption position, perhaps, the skew of bag 47 position and absorption position is during less than the judgement deviant that preestablishes and store in RAM, and CPU16 is judged as and does not satisfy the repairing condition (step S5) that spacing transmits.That is, be judged to be and do not need to repair.Like this, transmit, can automatically carry out the reparation that spacing transmits by above-mentioned minimum spacing.
As a result, after this, CPU16 work, adsorption mouth is carried out absorption, the taking-up action (step S8) of electronic component via element conveying end 45.At this moment, such as mentioned above, can from the bag 47 that spacing transmits, take out electronic component reliably.In addition, in the taking-up action of electronic component, by for example be shown as " spacing transmits to repair and finishes " in monitor 20,201, the operating personnel can confirm the situation that the reparation of spacing transmission is normally carried out.
In addition, when carrying out secondary bag of identification, satisfy the repairing condition (step S5) that spacing transmits, then stop the electronic component installation and operation of electronic element installation device 1 if CPU16 is judged as.In addition, for example show that in monitor 20,201 spacing situation about abending unusually takes place and spacing has taken place to transmit the unusual channel number of element feeding unit in the element supply device that is carried in transmitting.In addition, with the graphical display of captured bag and adsorption mouth in monitor 20,201, demonstration need be in that adsorption mouth be moved with respect to bag in absorption position alignment (order closes ゎ せ) picture of the absorption position that aligns the operation band transmit switch and the situation of the minimum spacing transmission carried out.
In addition, in absorption object elements feeding unit 13, when having connected new band for the element residue decreased number of band or the old band that do not remain element, when having detected the joint of old band and new band by detecting sensor etc., such as mentioned above bag to new band carries out bag identification, and carry out minimum spacing based on recognition result and transmit action, thereby even when being connected of old band and new band for example spacing be offset minimum spacing and under the situation about connecting, the spacing transmission also can be repaired automatically.
Then, the image of captured bag is identified processing unit 27 and obtains, and carries out image processing.Processing result image is sent to CPU16, and whether CPU16 judges electronic component in bag.Then, when not having electronic component, turn back to step 2 once more, in above-mentioned absorption object elements feeding unit 13, will be with and transmit a spacing.In addition, also can be identified in by recognition process unit 27 whether electronic component is arranged in the bag, and this result is delivered to CPU16 based on the image of identification video camera 14 shootings.
Similarly later on, the electronic component by step 5 have or not judgement, before being judged as electronic component, a spacing that repeats the band from step 2 to step 5 transmits, the electronic component the shooting of bag, image recognition, bag have or not judgement.
Then, the bag of having taken in electronic component arrives the element conveying end, and board recognition camera 14 is taken the bag of band via the element conveying end.And, element conveying end 45 as shown in Figure 6, with 46, the image of bag 47 and electronic component 48 is identified processing unit 27 and obtains, and carries out image processing.Processing result image is sent to CPU16, and whether CPU16 judges electronic component in bag.Then, CPU16 is if be judged as electronic component is arranged in the bag, and then the seeking after a processing finishes of electronic component, CPU16 output is used to begin to adsorb the signal of the action of seeking the electronic component that head finishes, and as described above, takes out these electronic components by installation head 10.In addition,, also can in RAM17, be provided for representing to seek the sign of a completed situation, thereby whether this element feeding unit 13 be judged when needing to seek automatically used afterwards for seeking the element feeding unit 13 that head finishes automatically.And then, for seeking the element feeding unit 13 that head finishes automatically, continue to manage by CPU16, do not change in element supply device even make, and when after this change of producing type is arranged, be not used in production, follow the switching of producing type and under situation about reusing, also this element feeding unit 13 is not sought the head action automatically.
Like this, before absorption object elements feeding unit 13 is not set (set), but when changing the new element feeding unit of installing 13 in back, CPU16 is judged as and need seeks the head processing automatically, such as mentioned above shooting results based on 14 pairs of bags of board recognition camera, before the bag of having taken in electronic component arrives the element region outlet, to be with at every turn and transmit a spacing, the head of seeking that automatically carries out electronic component moves, therefore when having changed absorption object elements feeding unit 13, the operating personnel does not need to seek an operation, result, can simplify preparation work, can shorten the activity duration.In addition, can avoid unusual reliably in operating personnel's the taking-up of seeking the electronic component that an operation produces when insufficient.
And then, can shorten operation and prepare the required time, thereby can also increase the duration of runs non-duration of runs that reduces electronic element installation device 1.
In addition, even on the empty passage of the feed appliance base 12 of element supply device 3 or 5, newly carried under the situation of element feeding unit 13, when beginning from element feeding unit 13 taking-up electronic components, perhaps, when producing the circuit board of next type even the production of a circuit board type in the electronic element installation device 1 finishes, changed under the situation of the element supply device 3 that carrying element feeding unit 13 or 5, during from each element feeding unit 13 taking-up electronic component, by with the replacing of said elements feeding unit 13 time similarly, the identification bag also automatically carries out the reparation that spacing transmits, thereby also can obtain same action effect.
Below, for the application's the 2nd execution mode, with the distinctive points of above-mentioned the 1st execution mode as the center, describe based on flow chart shown in Figure 7.
In the 1st execution mode, illustrated by can carry out bag identification with 46 situations of supplying element, but the 2nd execution mode is to use the band that can not carry out bag identification, supplies the embodiment of element by element feeding unit 13.
At first, the reparation that the spacing of the band when the installation and operation that carries out the electronic component of circuit board transmits is described.After adsorption mouth has been taken out electronic component, installation head 10,11 is by component recognition video camera 15 tops, unified 4 electronic components separately of taking 4 adsorption mouth, 101, the 111 adsorbed maintenances of two installation head 10,11 in this moves, the image of 27 pairs of these shootings of recognition process unit is discerned processing (step S11), calculates the position (component recognition result's calculating) (step S12) of the electronic component of each adsorption mouth 101,111 adsorbed maintenance.
Below, in the electronic component separately of adsorption mouth 101,111 adsorbed maintenances, electronic component that adsorption mouth kept of representative explanation.CPU16 obtains the component recognition result from recognition process unit 27, and based on the component recognition result, this electronic component is calculated spacing offset correction amount (step S13).That is, in the offset of electronic component with respect to adsorption mouth as the component recognition result, with the band direction of transfer in the element feeding unit 13, for example the side-play amount of the Y direction among Fig. 5 is calculated as spacing offset correction amount.
Normally whether the spacing offset correction amount that the CPU16 judgement calculates (step S14).Promptly, predefined spacing bias criterion value is (for example corresponding to the 2mm of the spacing of minimum, be 1.5mm) be stored among the RAM17, CPU16 judges that whether the spacing offset correction amount of result of calculation is greater than spacing bias criterion value (being outside the normal scope or within the scope).And, be spacing bias criterion value when above (, when being judged as outside the normal scope) in spacing offset correction amount, CPU16 sets the primary automatic reparation (step S15) that spacing transmits, and the sign of the intention that will set stores RAM17 into.And after this, the band that is used for element taking-up next time in the element feeding unit 13 transmits beginning (step S17), waits for finish (the step S18) of band transmission.
In addition, can show in monitor 20,201 that band transmits the situation of being repaired automatically, perhaps, thereby the minimum spacing of having set band transmits the automatic situation of repairing of band transmission meeting etc., by such demonstration, the operating personnel with the repair of transmission, also can know in electronic element installation device 1 automatically the situation with the reparation of transmission even without in person.
Then, finish if band transmits, then follow, CPU16 judges whether to have carried out automatic reparation and sets (step S19).Then, owing to set automatic reparation, therefore when CPU16 is immediately with above-mentioned bag identification similarly, element feeding unit 13 to the electronic component after the supply component recognition is exported the signal that minimum spacings transmit, thereby this element feeding unit 13 will be with transmitting the distance (for example 2mm) (step S20) preestablish the minimum spacing corresponding with element feeding unit 13 of storing in RAM17, with the reparation that transmits of spacing.Then, CPU16 waits for that finishing minimum spacing in element feeding unit 13 transmits (step S21), if finish, then waits for the absorption action (step S22) of electronic component.
In addition, when spacing offset correction amount is less than spacing bias criterion value in step S14 when being positioned within the normal range (NR) (be judged as spacing offset correction amount), CPU16 has stored automatic reparation when setting in RAM17, this is repaired setting automatically carry out initialization (step S16), the band that is used for element taking-up next time in the element feeding unit 13 transmits beginning (step S17) then, waits for finish (the step S18) of band transmission.
In addition, being judged as in the judgement of whether having carried out automatic reparation setting of step S19 does not have to set when repairing automatically, and the absorption of wait electronic component is moved and do not carried out minimum spacing and transmit (step S22).
Like this, using the band that can not carry out bag identification, when supplying element by element feeding unit 13, based on (in the mobile way of adsorption mouth) result of component recognition has carried out in the way of element installation action, in the offset of electronic component, the skew on the band direction of transfer in the element feeding unit 13 is calculated as spacing offset correction amount.And, in spacing offset correction amount is more than the spacing bias criterion value, when belonging to outside the normal range (NR), the signal that CPU16 transmits element feeding unit 13 output minimum spacings, the element feeding unit 13 of having imported signal is as mentioned above like that before electronic component takes out action next time, skew corresponding to the minimum spacing of the reason of the offset that becomes electronic component, band is transmitted the distance of minimum spacing, therefore the element supply position in the element feeding unit 13 is corrected the skew of minimum spacing, when next adsorption mouth is taken out electronic component, perhaps, after this when bringing line space into and transmit, the absorption mistake of adsorption mouth can be avoided, element can be further taken out reliably electronic component.
In addition, at this moment, when the side-play amount when the identification of element has the integral multiple left and right sides of minimum spacing, even if be not minimum spacing, also can be with the spacing (less than common transmission spacing) of the integral multiple of minimum spacing by once transmitting the correction of spacing skew.
Then, from finishing the element feeding unit 13 taking-up electronic components that minimum spacing transmits, take each electronic component of adsorbed maintenance, 27 pairs of images of recognition process unit are discerned processing.Whether normally and CPU16 calculates spacing offset correction amount (step S13) based on the identification result once more for this electronic component, judge spacing offset correction amount (step S14).
When spacing offset correction amount is more than the spacing bias criterion value, when belonging to outside the normal range (NR), CPU16 continues the judgement outside the normal range (NR), owing to be for the second time, therefore be judged as spacing and transmit unusually, and stop the electronic component installation and operation of electronic element installation device 1.In addition, for example show that in monitor 20,201 spacing takes place in transmitting unusual and situation about abending, spacing has taken place transmits the unusual channel number of element feeding unit in the element supply device that is carried.In addition, with the graphical display of captured bag and adsorption mouth in monitor 20,201, demonstration need be in that adsorption mouth be moved with respect to bag in the absorption position alignment picture of the absorption position that aligns the operation band transmit switch and the situation of the minimum spacing transmission carried out.
By such demonstration, it is unusual that the operating personnel can know that the reason that abends may be that the band of element feeding unit transmits, and know switch portion (band transmits Action Button) that needs executive component feeding unit 13 and the situation of carrying out the repair of minimum spacing transmission.
In addition, when spacing offset correction amount belonged within the normal range (NR), CPU16 set the primary automatic reparation of storing among the RAM17 and carries out initialization, and eliminates sign (step S16).Then, after taking out element, begin band and transmit (step S17), after the band transmission is finished,, therefore wait for the absorption action (step S22) of electronic component next time owing to do not repair setting automatically from element feeding unit 13.
After, the not shown configuration switch by the touch panel switch 21,211 that is provided with in monitor 20,201 for example is based on the result of bag identification, when having set the reparation of the spacing transmission that will carry out band, such as mentioned above, based on the bag recognition result, with the reparation that transmits of spacing.
In addition, using the band that can not carry out bag identification, when supplying element by element feeding unit 13, such as mentioned above, for example can be by operating in the not shown configuration switch of the touch panel switch 21,211 that is provided with in the monitor 20,201, based on the result of component recognition, set the reparation of the spacing transmission of whether carrying out band.
Embodiments of the present invention have been described as mentioned above, but to those skilled in the art, can carry out various replacement examples based on above-mentioned explanation, revise or distortion, the present invention comprises aforesaid various replacement example, revises or distortion in the scope that does not break away from its aim.
