The line chart of the state of the pressure variation in Fig. 5 adsorption mouth 105 that to be expression begin from the switching of switching with electromagnetically operated valve 124.Curve A is represented the common electronic unit that escape of air is less, and curve B represents to leak more electronic unit.In addition, in this line chart, expression air pressure in longitudinal axis top reduces, longitudinal axis below expression pressure rises.
As shown, if under the state of the upper surface butt of the leading section of adsorption mouth 105 and each electronic unit, begin negative pressure feeding, then under the situation of electronic unit arbitrarily, all after switch switching timing with electromagnetically operated valve 124 and produce some delays, produce the reduction of adsorption mouth internal pressure, under the situation of the electronic unit that escape of air is arranged, shown in curve B, the slope that reduces of this pressure slows down as can be known, and the time (absorption required time) that reaches till the target adsorptive pressure is elongated.
And, after reaching the target adsorptive pressure, stop negative pressure feeding (step S5) by the action of switching with electromagnetically operated valve 124, then, switch to malleation supply (step S6) by the action of switching with electromagnetically operated valve 124.Then, supply with, then will switch with electromagnetically operated valve 124 and close and stop malleation supply (step S7) if carry out malleation with the predefined time.Thus, the inside of adsorption mouth 105 returns to atmospheric pressure, and electronic unit is released from adsorbed state.Under above-mentioned state, Z axle motor 111 is controlled, so that adsorption mouth 105 rises to standby height (step S8), obtain control for the absorption required time of an electronic unit and finish.
In addition, above-mentioned absorption required time is obtained control and is carried out repeatedly, till all electronic units of preparing in to electronic component mounting apparatus 100 are all finished.
(discharge required time and obtain control)
Discharging required time and obtain control, is the processing that CPU 30 carries out according to the program in the ROM of system 12.For example carry out following processing: after the main power source of device rigidly connects logical back or just obtained new installation data, wait when not carrying out installation action and controlling, at each electronic unit that becomes mounting object in the installation data, the transport unit 101a (the perhaps recess of pallet 103) that adsorption mouth 105 is positioned at electronic unit feed appliance 101 locates, in this position, utilize adsorption mouth 105 attract electrons parts, the target adsorptive pressure will be made as in the adsorption mouth, begin the supply of malleation from above-mentioned state, measure the release required time till returning to the target release pressure.
In addition, this processing is carried out all electronic units of each the parts supply unit 102,104 that becomes mounting object in the installation data, and the release required time of each electronic unit is stored in the storage device 17.
In Fig. 6, illustrate that discharging required time obtains control.
At first, 30 pairs of X-axis motor 109 of CPU and Y-axis motor 110 are controlled, a certain adsorption mouth 105 on the boarded head 106 is positioned at as the transport unit 101a of the electronic unit feed appliance 101 of the electronic unit of object or the recess place (step S31) of pallet 103.
Then,, make adsorption mouth 105 drop to the absorption height (step S32) of electronic unit, then,, in adsorption mouth 105, carry out negative pressure feeding (step S33) by the switching of switching solenoid valve 124 by the driving of Z axle motor 111.Thus, the electronic unit in the recess of the transport unit 101a of electronic unit feed appliance 101 or pallet 103 is adsorbed mouth 105 absorption.
Then, with negative pressure feeding side by side, the output (step S34) of CPU 30 monitor pressures detecting units 125 reaches the timing of target adsorptive pressure in adsorption mouth 105, utilize to switch to stop negative pressure feeding (step S35) with electromagnetically operated valve 124.
In addition, under the situation that obtains the absorption required time, also can be in step S34, the monitor pressures detecting unit 125, and after waiting for through the absorption required time, stop negative pressure feeding in step S35.
Then, 30 couples of CPU supply with the time (release required time) that the inside that makes adsorption mouth 105 reaches till the target release pressure by malleation and measure.
Also can carry out timing in the above-mentioned measurement to beginning to be supplied to the elapsed time that pressure sensing cell 125 expression reached till the target release pressure from malleation, if but after wait detects the target release pressure by pressure sensing cell 125, switch switching, then sometimes owing to its response postpones with electromagnetically operated valve 124.
Therefore, obtain in the control at this release required time, control with electromagnetically operated valve 124 switching, so that at first, the state that reaches the target adsorptive pressure in the adsorption mouth 105 begins through predetermined time n[ms] after carry out malleation and supply with, its result, according to the detected pressures in the adsorption mouth 105 that obtains, judge that initial malleation service time n is long or too short, judge accordingly with this, on malleation service time n, add or deduct the unit interval of regulation, retry repeatedly, the best malleation service time that will be in adsorption mouth 105 boosts in the scope of atmospheric pressure till the malleation critical value (with this scope as " target release pressure ") is obtained as discharging required time.
In addition, the initial value of malleation service time n can utilize guidance panel 15 at random to set.In addition, the malleation critical value also can utilize guidance panel 15 at random to set, but must be set at more than or equal to atmospheric pressure, and does not make the electronic unit of installation because of air stream and be installed in the scope of its electronic unit generation offset on every side.
Fig. 7 is under the situation of the internal pressure that the is illustrated in adsorption mouth 105 target adsorptive pressure that is in three phases, switches with electromagnetically operated valve 124 to carry out switching controls and carry out the line chart of the state of the adsorption mouth 105 internal pressures variation under the situation that malleation supplies with predetermined stand-by period n.
Curve C is represented to change from the pressure that the target adsorptive pressure of negative pressure begins to apply under the situation of malleation, in the case, supplies with even carry out malleation with malleation service time n, also can not reach atmospheric pressure, and electronic unit can not be released from adsorption mouth 105.
In addition, curve D is represented to change from compare the pressure that becomes slightly under the situation that the target of malleation adsorptive pressure begins to apply malleation with C, in the case, if carrying out malleation with malleation service time n supplies with, then can reach atmospheric pressure, and be no more than the critical value of malleation, can carry out good adsorption and discharge.
In addition, curve E represents to change from compare the pressure that further becomes under the situation that the target of malleation adsorptive pressure begins to apply malleation with D, in the case, if carrying out malleation with malleation service time n supplies with, then can surpass atmospheric pressure, and surpass the critical value of malleation, electronic unit is discharged, but owing to may produce on every side jet, so electronic unit and near electronic unit thereof may be blown away.
As noted above, determine best malleation service time n accordingly with the target adsorptive pressure, obtain in the control discharging required time, malleation service time n is changed successively and explore optimum value.
Specifically, the supply of malleation begins (step S36), through behind the malleation service time n (step S37), by switching the control with electromagnetically operated valve 124, stops the supply (step S38) of malleation.Then, whether the adsorption mouth 105 interior detected pressures of judging the pressure sensing cell 125 of this moment are negative pressure (step S39), under the situation of negative pressure, think malleation service time deficiency, to on n, add 1[ms] and the value that obtains as new stand-by period (step S40), make to handle and return step S33.
Then, supply with negative pressure once more, till becoming the target adsorptive pressure after, with new malleation service time n[ms] supply with malleation, whether the internal pressure of judging adsorption mouth 105 is negative pressure (step S33～S39).The circulation of this step S33～S40 is carried out repeatedly, till the internal pressure of adsorption mouth 105 is more than or equal to atmospheric pressure.
In addition, in step S39, detect adsorption mouth 105 pressure inside, whether this internal pressure is judged (step S41) less than above-mentioned malleation critical value not under the situation of negative pressure.
Its result under the situation more than or equal to the malleation critical value, thinks that the malleation service time is long, will deduct 1[ms from n] and the value that obtains is set (step S42) as new malleation service time, makes to handle to return step S33.
Then, supply with negative pressure once more, till becoming the target adsorptive pressure after, with new malleation service time n[ms] supply with malleation, judge whether the internal pressure of adsorption mouth 105 is negative pressure, perhaps whether be not greater than or equal to malleation critical value (step S33～S41).The circulation of this step S33～S42 is carried out repeatedly, until the malleation critical value less than adsorption mouth 105.
By carrying out above-mentioned retry repeatedly, can obtain supplying with and make in the adsorption mouth 105 more than or equal to atmospheric pressure and less than the malleation service time of malleation critical value by malleation, it is obtained as discharging required time.
Thus, the inside of adsorption mouth 105 becomes the target release pressure, and electronic unit is released from adsorbed state.Under above-mentioned state, Z axle motor 111 is controlled, so that adsorption mouth 105 rises to standby height (step S43), the release required time of an electronic unit is obtained control finish.In addition, above-mentioned release required time is obtained control and is carried out repeatedly, till all electronic units of preparing in to electronic component mounting apparatus 100 are all finished.
(discharge required time and confirm control)

Then, with negative pressure feeding side by side, the output (step S64) of CPU 30 monitor pressures detecting units 125, driving by Z axle motor 11, adsorption mouth 105 is risen (step S65),, boarded head 106 is moved to discarded case 116 places (step S66) by the driving of X, Y-axis motor 109,110, by the driving of Z axle motor 111, make adsorption mouth 105 drop to discarded height (step S67) once more.
Then, during these action controls,, then stop negative pressure feeding (step S68) if adsorption mouth 105 inside reach the target adsorptive pressure.In addition, under the situation that is obtaining the absorption required time, also can be in step S64 monitor pressures detecting unit 125 not, but the timing that begins to adsorb required time in step S68, waits for through behind the absorption required time, and the supply of negative pressure is stopped.
Then, above discarded case 116, the supply (step S69) of beginning malleation waiting for through by (step S70) after discharging required time to obtain the release required time that control obtains, stops the supply (step S71) of malleation.
Then,, carry out negative pressure feeding (step S73), make adsorption mouth 105 rise to the identification height (step S74) of the component recognition apparatus 113 of lift-launch on boarded head 105 being supplied to wait through (step S72) behind the initial stand-by time m from stopping malleation.
Then, utilizing the result after component recognition apparatus 113 detects to be, even carried out the malleation supply, also detecting electronic unit is adsorbed under the situation of leading section of adsorption mouth 105 (step S75), think the stand-by time deficiency, to on m, add 1[ms] and the value that obtains as new stand-by time (step S76), make to handle and return step S67.Then, supply with negative pressure once more, after becoming the target adsorptive pressure, stop negative pressure feeding, and, supply with malleation to discharge required time, after stopping, after with new stand-by time m standby, judge whether electronic unit exists (step S67～S75).The circulation of this step S67～S76 is carried out repeatedly, until confirming that electronic unit does not exist.
Then, in step S75, there is not electronic unit in the front end that detects adsorption mouth 105 and under the situation about having fallen, the stand-by time m that finally obtains is stored in the storage device 17 end process.
In addition, above-mentioned release required time is confirmed control execution repeatedly, till all electronic units of preparing in to electronic component mounting apparatus 100 are all finished.

In addition, obtain control owing to outside installation action, implement the absorption required time individually, so by for example implementing to adsorb required time in the past and obtained control carrying out installation action, therefore be different from following situation, promptly, making a mistake and identify this for the first time when installation action is the electronic unit that is easy to generate the escape of air of electronic unit, thereby implement to leak the situation of countermeasure, thereby, even each electronic unit is not carried out under the situation of leakage characteristics identification the operating personnel, also can be automatically with leakage characteristics accordingly, carry out installation action, and reduce wrong generation more.
In addition, owing to obtain the execution of control by the absorption required time, to adsorb required time at each electronic unit and automatically be stored in the storage device 17,, can eliminate miscellaneous property of setting operation so do not need the operating personnel that the leakage characteristics of each electronic unit is set the input operation.
In addition, because the absorption required time is obtained the measurement of the absorption required time in the control, be in the recess of the transport unit 101a of electronic unit feed appliance 101 or pallet 103, to carry out, and, after measurement, supply with malleation, after the absorption of carrying out electronic unit discharges, adsorption mouth 105 is risen, so electronic unit can not be raised, therefore, obtain in the control at the absorption required time at least, can not produce discarding of electronic unit etc., can prevent the waste of electronic unit, realize the raising of economy.
In addition, owing to obtain the execution of control by discharging required time, can be at each electronic unit that becomes mounting object, obtaining the inside that makes adsorption mouth 105 becomes from atmospheric pressure release required time of (target release pressure) to the scope between the malleation critical value, so when installation action is controlled, according to the release required time of obtaining, the release of adsorbing thus, can discharge electronic unit more reliably, suppress taking back of electronic unit, can realize the raising of reliable in action.
In addition, because when not carrying out installation action control, carry out the release required time and obtain control, obtain control so for example before installation action, carry out the release required time in advance, therefore be different from following situation, promptly, making a mistake and identify this for the first time when installation action is the electronic unit of taking back that is easy to generate electronic unit, thereby implement the situation of countermeasure, thereby, even each electronic unit is not identified under the situation that is easy to generate the characteristic of taking back, also can automatically avoid the installation action taken back, and reduce wrong generation more the operating personnel.
In addition, because for discharging required time, also obtain control and the time automatically be stored in the storage device 17, do not take back and set the input operation, can eliminate miscellaneous property of setting operation so do not need the operating personnel whether to be easy to generate at each electronic unit at it.
In addition, owing to obtain in the control at above-mentioned release required time, make and discharge little by little variation of required time, retry repeatedly, obtain and make the adsorption mouth internal pressure become suitable release required time, so can under the state that comprises by the influence of switching the time difference that causes with electromagnetically operated valve 124, obtain the release required time, under the situation about in the action control of installing, implementing, also can reproduce identical result.
Therefore, can measure the release required time more accurately, more effectively prevent taking back of electronic unit, and, the offset of other electronic units in the time of can preventing installation action.
In addition, owing to confirm that by discharging required time control obtains stand-by time, and, when installation action, adsorbing by the supply of malleation on the basis of release, adsorption mouth 105 is risen during stand-by time, but make its standby, so can prevent taking back of electronic unit more reliably.
(other)
In addition, in above-mentioned action control unit 10, implement the absorption required time respectively and obtain control and discharge required time and obtain control, but also can be by a series of action control, and obtain absorption required time and release required time the two.
Promptly, owing to when discharging the obtaining of required time, must in adsorption mouth 105, carry out negative pressure feeding, after becoming the target adsorptive pressure, the beginning malleation is supplied with, and become suitable pressure, so also can in making adsorption mouth 105, become the target adsorptive pressure time, the service time of negative pressure is measured, obtain the absorption required time, then, carry out malleation with preset time and supply with, judge the processing in the scope that whether becomes the target release pressure in the adsorption mouth.
Be described more specifically, the negative pressure feeding of step S33 from Fig. 6 picks up counting when beginning, in step S34, monitor adsorption mouth pressure,, can obtain the absorption required time by measuring the time that in step S35, becomes till the target adsorptive pressure stops negative pressure feeding.After step S36 after, as noted above control obtained the release required time thus.In addition, because step S39 and S41 are the judgement of "Yes", and carry out under the situation of retry, processing for the later step S33～S35 that circulates for the second time, preferably do not carry out timing, but, control so that negative pressure feeding stops by supervision to pressure sensing cell 125.
As noted above, the absorption required time is obtained control and the release required time is obtained control by carrying out in a processing, can not need the absorption required time of Fig. 4 of carrying out separately to obtain control, shortening obtains the absorption required time and discharges the needed time of required time significantly.
