Contactor shown in the example comprises the flexible metal plug-in strip 58,68 of two series, and this plug-in strip is arranged in pairs and pushed the contact pin of parts to be tested in the mode of the jaw clamping of pliers, can only see first pair of plug-in strip in Fig. 1.Contactor moves both vertically open and close relatively by two jaws 56,66.Each jaw cylinder 57,67 by electric insulation in its motion drives in the flexible plug-in strip 58,68 of two series.Each jaw 56,66 is fixed at the terminal part place on axle 55,65, and this is led by the vertical cylinder that passes framework 1.
In its preferred embodiment, linear electromechanical converter makes the motion of actuating system of the present invention, and this linearity electromechanical converter is a line motor.This line motor comprises two permanent magnet pieces 2,3 and is arranged on movably electric coil 4 between this magnet, and the control system (not shown) that comprises motor sends through the varying strength of this coil and the continuous current of direction, produced a power based on coil 4 like this, this power makes the balladeur train 8 on its guide rail be subjected to displacement.The direction of displacement of this balladeur train can change by the sense of current that makes flowing through coil 4 is reverse.
By making the sense of current alternate of flowing through coil 4 apace, can between two discrete positions of balladeur train, produce and move back and forth fast, cause the quick-make of contactor like this and open.
Detect the inductive pick-up 93,94 of screw element 95,96 appearance and inform that control system is in the position of the balladeur train at its first or second discrete positions place, beginning or the balladeur train for check is in the moment that previous position to be determined can provide the best like this.
The motion of the motion of linear movement generator, particularly line motor is unmanageable.Difficulty is speed and the amplitude that accurately limits sledge movements especially, therefore is difficult to do not stopping balladeur train against retainer 91,92 under the situation of resilience.This motion generator that is used for the contactor of actuating electronic parts makes on the adaptive control system that by it is attached to its use becomes possibility, reduce the speed of plug-in strip during near parts to be tested step by step with the flexible plug-in strip 58,68 of guaranteeing contactor, and limit the maximum press power of plug-in strip 58,68 especially, so that can not damage parts to be tested, and obtain qualified electrically contacting, be enough to carry out check in good condition.
With reference to Fig. 2, in a preferred embodiment of the invention, control system comprises two connecting rods 5,6, and this connecting rod is fixed on the balladeur train 8 by its lower shaft.The upward axle of head rod 5 directly is fixed to first 55 bottom, and this first is directed in the vertically-guided spare that passes system framework 1.Second 62 of second connecting rod 6 is connected on the reverse bar 7, and this reverse bar is configured to by the approximate horizontal placement and rigid metal spare that can center on the rotational that is in its middle part.Another terminal part of this reverse bar 7 is connected to second 65 lower end portion, and this second also is directed in the vertically-guided spare that passes system framework 1.
When balladeur train 8 was in its first discrete position, it was against retainer 91, and connecting rod 5,6 is with respect to vertical plane α at angle, and their second position, its underpart that is on the vertical axis.Jaw 56 is pulled down by axle 55, and jaw 66 is upwards pushed away by axle 65, and this axle 65 is connected to second connecting rod 6 through reverse bar 7.Contactor is opened, and parts move to next station from an operation position.In the preferred embodiment of example view of the present invention, when contactor was opened, these connecting rods had identical length and become identical angle [alpha] with respect to vertical plane.Should contemplate equally,, and can make the contactor action by means of the also motion of may command linear electromechanical converter of the present invention of connecting rod of different length and position.
When balladeur train 8 was in its second discrete position, it was against second retainer 92, and connecting rod 5,6 is in the position of approximate vertical.They second thereby be in its extreme higher position on the vertical axis.Jaw 56 is upwards pushed away by axle 55, and jaw 66 is pulled down by axle 65 by reverse bar 7.The contactor closure can be carried out the check of parts.
The effect of connecting rod 5,6 is illustrated by Fig. 2.When contactor was opened, connecting rod 5,6 was angled with respect to vertical plane.The lower shaft that is connected to the connecting rod 5,6 on the balladeur train moves horizontally.Be connected to one or oppositely the axle of going up of the connecting rod 5,6 on the bar 7 be directed to along moving both vertically.When balladeur train 8 when its second discrete positions moves with closed contactor, connecting rod 5,6 is in vertical position.The horizontal displacement b of balladeur train derives the vertical displacement d that goes up axle of connecting rod 5,6.The relation of displacement b and d is by following formulate:
Like this, if angle [alpha] is held in little angle, the vertical displacement of going up axle of connecting rod is held in the horizontal displacement that is significantly less than its lower shaft.The derivation of above formula also illustrates, and vertical displacement speed reduces significantly when near the upright position of connecting rod 5,6.
Relation between vertical displacement and the horizontal displacement provides following advantages.
First advantage is, when near and during the contact point of parts to be tested, the speed of the flexible plug-in strip 58,68 of contactor reduces.Near the upright position of connecting rod, balladeur train is horizontal displacement apace, and in this case, the vertical speed that goes up axle of connecting rod 5,6 reduces greatly, so the speed of the plug-in strip 58,68 of contactor reduces greatly.
Second advantage is that near the vibration of balladeur train 8 position to flexible plug-in strip 58,68 its second discrete positions does not almost influence.
The 3rd advantage is that the power of linear electromechanical converter increases exponentially.Therefore, on parts to be tested, contactor remained on the power that make position only need be applied minimum degree by converter.
Additional advantage is, because the upright position of going up axle of connecting rod 5,6 has reached bare maximum, so also reach can exactly determined maximum for minimum range between the jaw 56,66 of contactor, acting on thus that extruding force on the parts of special type or press power also reach can exactly determined maximum.
The sledge movements that surpasses its second desirable discrete positions causes contactor slightly to be opened again, has prevented the damage of parts to be tested like this or has prevented that flexible plug-in strip 58,68 exceedingly is forced to.The accurate moment of closure that acts on the contactor of parts to be tested is determined by means of second inductive pick-up 94, and the accurate moment of its detection can be regulated by acting on second screw element 96.
In the variant embodiment of actuating system of the present invention, do not use reverse bar 7, and the upward axle of second connecting rod 6 directly is fixed to second 65 lower end portion.When balladeur train 8 presses first retainer 91,, can realize the function of reverse bar for example by the perpendicular positioning of second connecting rod 6.By this way, cause second of head rod 5 axially to be gone up moving and cause second of second connecting rod 6 axially to move down towards the carriage advance of second discrete positions of balladeur train, so that it is positioned to and vertical plane α at angle, this makes jaw 56,66 move with drawing close each other.
Preferred embodiment described above is described the actuating system of the contactor that is used for electronic unit in detail with reference to example, the motion of this system is produced by the horizontal linearity line motor, and this system is used for activating by controlling organization, this controlling organization comprises two connecting rods, and contactor moves along vertical axis.
Yet, principle of the present invention also can be applicable to the generator of any linear movement, and it comprises pneumatic jack or impulse motor, perhaps is applied to the generator of circus movement, it comprises the revolving cylinder engine that activates bent axle, and the connecting rod of some is housed on bent axle.Yet, should after embodiment have bent axle usually and make complicated shortcoming.
In variant embodiment of the present invention, the electromechanical converter has the discrete positions greater than two limited quantity, corresponding to the number needs compacting actuating system of discrete positions, so that for example contact each parts, the setting of the contact point of these parts is than complicated like this.
By the contactor of this system activation can be above example dissimilar in described.For example it can comprise the jaw of the flexible plug-in strip of one or more pairs of actuatings; One or more pairs of such jaws, its upper gripper jaw or following jaw are movably; One or more pairs of flexible metals plug-in strip contacts by being pressed in the parts that make on its contact point with to be tested; Or the combination in any of these systems.It can be the parts that are used for the grid matrix formula, the form of " contact pin grid matrix (PGA) " or " spherical grid matrix (BGA) " for example, wherein contactor then comprises for example hard contact plate, and it is arranged to relative with the contact of parts and applies against its lower surface.
These dissimilar contacts need the adaptive of actuating system of the present invention, make that for example actuating system can comprise only connecting rod, to be used to start the contact of single series; Perhaps opposite is, can comprise different length and become a plurality of connecting rods of different angles with vertical plane, so that act on the different key elements of the contactor motion with friction speed and amplitude.
