The specific embodiment
Turn to Fig. 1 now, show the block diagram of ultrasonic welding system 10 according to an embodiment of the invention.Supersonic generator 12 comprises multiple probe controller (MPC) 14.Fig. 1 illustrates the MPC14 that is implemented as master control MPC unit 15 and subordinate MPC unit 16.Each MPC unit is connected 20 to a plurality of ultrasonic probe 18a-h transmitted powers via the probe that is connected with ultrasonic power jack 22.Supersonic generator 12 is ultrasonic probe 18 power supplies according to the signal that receives from automatic control system 24.Automatic control system 24 is a kind of selector input units that can use with native system.Alternatively, can use in certain embodiments and be used to ask ultrasonic probe to select and be used to ask the activation of ultrasonic power and the manual switching control of deexcitation.
Power from supersonic generator 12 is to be transported to ultrasonic power input 28 set on the master control MPC unit 14 from ultrasonic power output 26.System's output 30 of supersonic generator 12 is transmitted to the automatic control input end 32 of automatic control system 24 with signal, and the system input 34 of supersonic generator 12 is from automatic control output end 36 received signals of automatic control system 24.
Signal input part on the automatic control system 24 comprises MPC ready signal input 38, ultrasonic power status signal input 40 and the public input 42 of watch-dog signal.The signal output part of automatic control system 24 comprises a ultrasonic activation output 44 and a probe selection position output 46,48 and 50.Select the position though show three probes in the embodiment in figure 1, more or less probe can be set according to the quantity of the ultrasonic probe 18 that will select select the position.For example, the 4th probe can be set and select of the selection of position output with 16 probes of as many as of allowing to utilize hexadecimal code.It is binary add power and positions that probe is selected position 46,48 and 50, and its meta 0 is that least significant bit and position 2 are highest significant positions.Use three, can select up to 8 different ultrasonic probes.This method has the advantage that automatic control system of making 24 can not be selected two probes simultaneously, stops each the activation more than one the probe selective relay as expectation.Public (ground connection) splicing ear 52 also is set between automatic control system 24 and the supersonic generator 12.Below, the function of each signal in these signals is understood with reference to their description.
Be used for the ultrasonic welding probes that ultrasonic probe 18 of the present invention can comprise any kind, described ultrasonic welding probes comprises the optimised ultrasonic welding probes of instrument that is used for special ultrasonic bonding application.Can control according to weld interval by the control of the timers in the automatic control system 24 or by the ultrasonic bonding time of controller control weld intervals set in the supersonic generator 12, perhaps can measure ultrasonic power and be that unit quadratures with the welding energy of the specific quantity that causes being used for specific weld with the watt-second.According to an embodiment, which probe 18 is automatic control system 24 can select to be used to weld interval, and also can be by sending the duration that activation signal is controlled welding from ultrasonic activation output 44 to supersonic generator 12.Then can offer automatic control system 24 with the output of ultrasonic wave status signal point-device if desired weld interval, to allow the actual duration timing of 24 pairs of ultrasonic wave outputs of automatic control system.
Welding timer in the supersonic generator 12 can have the window that is used to define acceptable welding assembly of user-programmable.For example, system can be programmed to utilize energy to come welding assembly and ultrasonic welding system 10 can be set to 500 joules welding energy.Welding controller in the supersonic generator will control supersonic generator 12 and apply ultrasonic wave, be applied in to parts up to the energy of 500 watt-seconds, but second time window or limit can be programmed with the fault in the testing process.In above-mentioned example, when welding is correctly finished, for parts, may be typically the ultrasonic power of 500 watts of pumping, this will cause about 1 second cycle time.Time window can be programmed, if so that outside predefined time window (for example, less than 0.5 second or greater than 2 seconds) reach the energy level of being programmed, then parts can be marked as parts inferior or to be checked and can use automation equipment that parts are chosen in the suitable components case in some instances.
Ultrasonic welding system 10 allows to supply ultrasonic powers from supersonic generator 12 to a ultrasonic probe 18 at every turn.MPC ready signal from MPC14 is notified automatic control system 24 after the belling cycle that power supply termination and ultrasonic probe to another ultrasonic probe 18 stop to vibrate, when can select position 46,48 and 50 for new ultrasonic probe 18 changes.
Referring now to Fig. 2, show the sequential chart of ultrasonic welding system 10 according to an embodiment of the invention.MPC ready state signal 54 is sent to the MPC ready signal input 38 of automatic control system 24 from system's output 30 of supersonic generator by MPC14.MPC ready state signal 54 provides MPC14 when to be ready to the indication of powering for different ultrasonic probe 18.Ultrasonic power status signal 56 is sent to the ultrasonic wave status signal input 40 of automatic control system 24 from system's output 30 of supersonic generator 12.The probe of selecting signal 58 (in fact probe selects the result's of position figure to describe) demonstration to be undertaken by automatic control system 24 of popping one's head in is selected over time.Ultrasonic activation signal 60 is sent to the system input 34 of supersonic generator 12 and indicates automatic control system 24 when to attempt beginning providing ultrasonic power for selected probe 18 from the ultrasonic activation output 44 of automatic control system 24.Ultrasonic wave voltage output signal 62 shows that the probe of the probe that has activated connects 20 voltage.
When the time shown in Fig. 2 begins, at moment t 0, select sensor 's number 1 and do not give the probe power supply.In addition and since MPC ready state signal 54 be set to its ready state (low, as shown), so automatic control system 24 can freely select another probe to power.t 0The back short time is promptly at t 1, probe is selected to be changed into selecting sensor 's number 5, as selecting shown in the signal 58 by probe.Synchronous logic in the multiple probe controller 14 need be in the delay between the activation of new selection of popping one's head in and ultrasonic power.For example, in one embodiment, the automatic control system 24 that needs synchronously in the multiple probe controller 14 is at t 1, when promptly selecting sensor 's number 5 and t 2, the proper operation between being ultrasonic activation signal 60 when its high unactivated state is changed into low state of activation provides the delay of minimum 40ms.Basically when ultrasonic activation signal 60 activated, MPC ready state signal 54 was changed into its high not-ready state from its low ready state at once.After short time, at t 3, ultrasonic power status signal 56 shows that from it high state of not supplying ultrasonic power changes into it and show the low state of just supplying ultrasonic power.t 2And t 3Between time delay be because MPC14 does not come the fact of work according to the synchronous logic identical with automatic control system 24.Automatic control system 24 takes place and can't help and directly controls in the startup of ultrasonic power according to the synchronous logic of MPC.
Ultrasonic power activates and lasts till t always 4, be that ultrasonic activation signal 60 is changed into its high unactivated state from its low state of activation.Basically in the conversion of this state, ultrasonic power status signal 56 shows that from it low state of just supplying ultrasonic power changes into the high state that its supply that shows ultrasonic power has stopped.Ultrasonic power status signal 56 changes simultaneously with deexcitation signal from ultrasonic activation signal 60, takes place because the deexcitation nonpassage of signal is crossed the synchronous logic of MPC 14.
At t 4Afterwards, the belling cycle in ultrasonic wave voltage output signal 62 appears, up to t 5The belling time is to change according to the characteristic of the particular probe 16 that is de-energized, and this characteristic comprises the characteristic of clamping pressure of for example ultrasonic wave superimposed characteristics and probe and so on.After the belling cycle, at t 6The time, MPC ready state signal is not changed into low (ready) from high (ready), thus the indication probe is selected and can be accepted by MPC unit 14.In addition, t 5And t 6Between the time retard be because the asynchronous relationship between the synchronous logic of belling time and MPC14.At t 2And t 6Between, probe selects any change of signal 41 all will be ignored by master control MPC15 or subordinate MPC16, because MPC ready state signal 54 is set to height (not ready).

Master control and subordinate multiple probe controller 15 and 16 operations are used to monitor the probe state variation that ultrasonic probe state and formulation system user or automatic control system 24 are asked.The signal trajectory explanation of following is according to the operation of the ultrasonic welding system of some embodiments of the present invention.
Referring now to Fig. 5, show the signal trajectory of the timing sequence that powers on according to an embodiment of the invention.Show the time along the x axle, wherein the interval of each dotted line represents 20ms at interval.When ultrasonic welding system is switched on, power on fixed between sequence be activated.Power on and reset case during, multiple probe controller 14 starts the master control reset signals, all relays contacts of deexcitation, and disable synchronization clock.In the embodiment shown in Fig. 5, synchronizing clock signals track 1 72 shows that in this embodiment the synchronised clock with the speed work of about 30Hz switches to its non-reset mode (shown in the low signal) in master control reset signal 174 from its reset mode (shown in the high signal) and begins the vibration of about 60ms afterwards.Master control reset signal 174 switch to from its height or reset mode low, be non-reset mode after, multiple probe controller ready state signal 54 switches to its low or about 45ms of ready state.In the embodiment shown in Fig. 5, after powering on, switch to low, be non-reset mode before, master control reset signal 174 is in high state and surpasses 40ms.When synchronizing clock signals 172 was activated, the first relay activation signal 176 was low from it, be that off status is changed into its height, promptly opened state, and this starts by the first synchronised clock rising edge.In this, relay 76 has received and has been used to activate first relay ultrasonic power input 28 is connected to the signal of the first ultrasonic probe 18a, as shown in Figure 3.
Referring now to Fig. 6, show the signal trajectory of breaker timing sequence according to an embodiment of the invention.In the signal trajectory of Fig. 6, each dotted line time interval is approximately 200ms.Between turnoff time, the contact of the relay of activation should keep and can operate, and drops to safety level until the ultrasonic wave voltage level.Fig. 6 illustrates the timing sequence when during the welding interval that is activated in ultrasonic wave output the input outage taking place.In the embodiment shown in Fig. 6, the ultrasonic wave voltage 178 on the ultrasonic probe was connected at first in the shown time.Belling signal 180 is high in the shown time at first, is in non-belling state.Power-off signal 80 is low, and indication is outage not.Relay contact watch-dog signal 182 is high, shows that the relay 76 corresponding to ultrasonic probe is activated.In when outage, i.e. about 500ms after the waveform of Fig. 6 is caught beginning, power-off signal 80 switches to height, and indication is cut off the power supply and is taken place.Ultrasonic wave voltage output 178 approximately decays near 0 volt in the 350ms after outage.Belling signal 180 becomes low with indication belling state, the power attenuation that is supplied to ultrasonic probe during this belling state was switched back the high and high approximately 650ms of maintenance of logic at local power supply voltage then to safety level before collapse on the ultrasonic wave voltage detecting circuit 104 shown in Fig. 3.The belling signal normally moves, and has tolerance power supply duration of about 600ms for ultrasonic wave stack (ultrasonic stack) with the bell time response of yowling or probe.Relay contact watch-dog signal 182 indicating relays are closed (height), and this is normal condition during welding interval.It is high that relay contact watch-dog signal 144 keeps between turnoff time, shows the belling time after that approximately relay contact maintenance is closed in the 600ms, collapses until relay coil voltage.
Referring now to Fig. 7, show the signal trajectory that the relay of popping one's head in is according to an embodiment of the invention selected timing sequence.Multiple probe controller guarantees that the selection of the relay (and therefore new welding probe) of new activation finishes to be timed with synchronous mode.In this embodiment, synchronizing clock signals track 172 is shown as the frequency work with about 32Hz.When probe select position 0 signal 92 synchronised clock along before approximately 10ms asynchronously when switching to corresponding to the selection of the second ultrasonic probe 18b low corresponding to the selection of the first ultrasonic probe 18a high, on the synchronised clock edge that the next one rises, first relay is connected so that be the power supply of first ultrasonic probe, shown in first relay signal 184, and second relay cuts off simultaneously, shown in second relay signal 186.When ultrasonic power is switched on, synchronizing clock signals 172 disabled (pass), so relay switch to change not having under the situation of clock be impossible be linked because relay switches to change to change with clock status.At this time durations, probe selects the signal variation on the input to be left in the basket.
Referring now to Fig. 8, show the signal trajectory that the relay of popping one's head in is according to an embodiment of the invention selected timing sequence.In the embodiment shown in Fig. 8, synchronizing clock signals 172 is with the frequency work of about 32Hz.Also shown by multiple probe controller 14 and selected position 0 signal 92 from user selection device or from the probe that automatic control system 24 receives.In the signal trajectory of Fig. 8, the high signal of selecting position 0 is corresponding to selection first ultrasonic probe, and the low signal of selection position 0 is corresponding to selecting second ultrasonic probe.Select position 0 signal 92 when ultrasonic wave and change into when selecting the low state of second ultrasonic probe corresponding to high state of selecting first ultrasonic probe from it, the first relay activation signal 184 at the next rising edge of synchronizing clock signals 172 from activating or high state is changed into deexcitation or low state.The second relay activation signal 186 is changed into activation or high state at the identical rising edge of synchronizing clock signals 172 from deexcitation or low state.In this special example, select the starting relay that changes to of position signal 92 to select the rising edge of the synchronised clock 172 of variation to have the asynchronous delay time of about 25ms from probe.Though it should be understood that in the embodiment shown in Fig. 8 to change along activating, can change along activating at the decline clock in other embodiments, as may considering to wish at design at the rising clock.
Referring now to Fig. 9, show the signal trajectory of ultrasonic activation timing sequence according to an embodiment of the invention.This figure shows that ultrasonic power activates the synchronization timing sequence, and it is used to activate the ultrasonic power to the probe of having selected in advance.Fig. 7 and probe shown in Fig. 8 select rising clock that logic utilizes synchronised clock along coming switching state and select different relays in an illustrated embodiment, and the ultrasonic activation logic shown in Fig. 9 is used for the trailing edge of synchronised clock to activate.
In Fig. 9, each dotted line that time shaft shows is spaced apart 5ms.Synchronizing clock signals 172 shows the frequency work of synchronised clock with about 32Hz.When not producing the activation request, ultrasonic activation signal 60 is high, when having produced the activation request, for low.The ultrasonic activation signal 60 that enters into the MPC logic is logic asynchronous and can at any time take place with MPC.Ultrasonic activation inhibit signal 110 postpones the activation of ultrasonic power with MPC logical synchronization and its, up to the first negative clock along appearance.For example, in Fig. 9, change up to the first negative clock along the delay that nearly 25ms occurs from the state of ultrasonic activation signal 60, when the first negative clock edge occurs, ultrasonic activation inhibit signal 110 switches to its height (activating or startup) state, can supply ultrasonic power in this, shown in ultrasonic power status signal 56, this ultrasonic power status signal switches to its low state to show power-on.
For the synchronous logic protection is described, suppose that the same automatic control system in a flash 24 that changes at ultrasonic activation signal 60 changes probe and selects the position.New probe relay will be at the first rising clock along selected, as shown in Fig. 7 and Fig. 8.According to an embodiment, the activationary time standard of relay circuit 52 (shown in Fig. 3) is 5ms to the maximum, thus the decline clock before activate the ultrasonic wave of exporting to selected ultrasonic probe by selected relay at least in the 10ms relay contact should be closed.In this embodiment, activate ultrasonic power and change probe simultaneously that to select the position be not recommended program, because if the decline clock is along at first occurring, then probe is selected the position not have to be used to influence the rising clock edge that probe is selected.To can not run into rising clock edge in this case, because synchronizing clock signals 172 is disabled when ultrasonic power activates.For correct work, automatic control system 24 goes up at MPC ready signal input 38 (shown in Fig. 1) and receives the indication of MPC ready state.When receiving MPC ready state when indication, automatic control system 24 can utilize probe to select position output 46,48 and 50 (shown in Figure 1) to select desirable probe, waits for 40ms at least before starting welding interval connecting the ultrasonic activation signal then.
In order to take action by the ultrasonic activation request from ultrasonic wave sequence unit or user, activating inhibit signal 110 must be activated, and is in it and activates high state.This allows only to activate the output of ultrasonic wave voltage via sync logic.With reference to Fig. 9, ultrasonic activation signal 60 switches to low, to signal the request that starts welding interval.On the negative synchronised clock edge of the next one, ultrasonic activation inhibit signal 110 from low, be that the ultrasonic power illegal state switches to height, is the ultrasonic power starting state.This change is the disable synchronization clock during welding interval.The height that ultrasonic power status signal 56 does not have ultrasonic power to be provided from indication switches to the output of indicate ultrasound ripple and just is being provided for the low of welding interval.
Referring now to Figure 10, show the signal trajectory of ultrasonic wave deexcitation timing sequence according to an embodiment of the invention.Ultrasonic wave deexcitation timing sequence is handled the power-down logic of ultrasonic probe, and guarantees that power will can not be supplied to the ultrasonic probe of new selection, stops up to the work and the power consumption of the ultrasonic probe of just working.Synchronizing clock signals 172 shows, unripe at MPC ready state signal 54 indication multiple probe controllers be the new ultrasonic probe of selecting when powering, and clock is not worked.When ultrasonic activation signal 60 lowly switches to indication and supplies with the power of ultrasonic probe when cut high from what indicate ultrasound ripple probe was activated, belling status signal 181 is from showing the effectively low height of indicating disabled ultrasonic probe to be in the belling state that switches to of no belling, ultrasonic probe is allowed to the failure of oscillations during the belling state, and select to change for probe takes place, ultrasonic wave voltage reaches safety level.Belling status signal 181 shown in Figure 10 available belling signal testing point from the main control board of multiple probe controller is caught.On the contrary, the belling signal 180 of Fig. 6 is directly caught on the output pin on the programmable logic device shown in Fig. 3 64.Though the logic of given these outputs is inverting each other in an embodiment, they all are to derive from the identical output signal of programmable logic device 64.In the embodiment shown in Figure 10, belling status signal 181 activates about 90ms and stops any other ultrasonic wave voltage output or probe to switch during this period after the deexcitation of ultrasonic wave voltage.Multiple probe controller ready state signal 54 keeps not-ready state (height), and after belling finished, after multiple probe controller ready state signal 54 switched to its low (ready) state, synchronised clock 172 brought into operation then.In the embodiment shown, the belling signal is determined according to the signal that is produced by the ultrasonic wave voltage detecting circuit shown in Fig. 3 104.
Automatic control system 24 necessary nearly all timings of observing are eliminated in the use of synchronous digital logic to be needed.According to some embodiment, unique timing need be that at least one section setting-up time before ultrasonic power is activated (for example, 40ms) probe must take place and select (when multiple probe controller 14 is ready).The synchronous logic of multiple probe controller 14 is introduced some with the timing uncertainty that the external ultrasonic activation signal takes place, and described external ultrasonic activation signal is asynchronous with internal logic in certain embodiments.Utilize inner (integrated) welding timer, will allow synchronous logic and eliminate this timing uncertain.
Turn to Figure 11 now, show state transition graph, this state transition graph shows the general sequence according to the incident of above-mentioned signal trajectory.When powering on or reset, as shown in the piece 188, be transformed into the starting state in the piece 190, under this starting state, forbid welding but the relay selection of can popping one's head in.This state is shown in Fig. 7 and Fig. 8, as mentioned above.When the relay of popping one's head in is selected, be transformed in the state of activation shown in the piece 192, as shown in Fig. 9, be transformed into welded condition 194 as top afterwards, its final selection by the signal trajectory of Fig. 9 is represented.When the welding duration finishes, be transformed into deactivation status 196 (as shown in Figure 10) and be in safety level up to ultrasonic wave voltage, select and welding interval to continue probe so that can be switched to starting state 190.If outage or power supply are closed, then be transformed into off-position 198 as shown in Figure 6, up to powering on or resetting.
