- the module comprises a base element, a holder and guide elements.
- the guide elements are designed such that the interface unit can be moved by a rectilinear, translational movement from an end position to an intermediate position and from the intermediate position into a removal position, which is arranged outside the test system.
- the mechanism comprises a lever mechanism which is controlled by a link which is movably mounted transversely to the rectilinear translational movement of the holder.
- a merging device is configured to merge a handler or prober first device with a second device consisting of an electronic component test head, the docking device being attachable to the first or second device.

- a handling device is understood to be a handler or a prober.
- merging means that the first and second device via a predetermined path, which is preferably at least 10 cm, in particular at least 15 cm or 20 cm.
- the front insertable into the pin receiving portion of the catch pin extends from the front end of the catch pin to locking means of the latching device, which engage the catch pin.
- test head When connecting the test head to the handling device, the test head is usually held by a manipulator in order to bring it to the handling device and to position it. So far, the test head and the handling device have been manually merged by the operator of the test facility. Only when the test head is arranged directly adjacent to the handling device, ie, has a distance of less than 5 cm, the two devices were connected to one another by means of a docking device and aligned exactly with one another.
- test head with respect to the handling device was very complicated and usually required two operators.

- the length of the linear path around which the pin receptacle can be displaced by means of the linear displacement device can be of any desired length. This is because the way in which the pin retainer is displaceable is not hampered by the arrangement of the mechanical structure of the linear linear displacement device. This means that the movement device is arranged next to or laterally offset from the pin housing or a pin space and not in the area in which the pin holder is displaced.
- the merging device may have a certain play relative to the catch pin. This simplifies the merging of the test head and handling device in addition, since catch pin and locking device do not have to be aligned so precisely in their linear alignment.

This leaves latching elements, such as e.g. Balls, the locking device fixed in its rest position, only by releasing the locking of the locking pin, the locking elements in the outer engagement with the catch pin can be brought.
- the securing device may also comprise a spring element, such as e.g. Have plate springs or a coil spring, which must first be compressed with a predetermined force to bring the locking elements au engagement with the catch pin.
- the merging device can also be designed such that the catch pin in the retracted state rests against a stop, so that the device is designed not only for merging but also for aligning and positioning of handling device and test head to each other.

- Such a system may also include a drawer element discussed above.
- test head It is often not easy to arrange the test head due to its high weight in its relative position to the handling device so accurate that a connection of the handling device and test head with a conventional Drehringvor- direction is not possible. If the test head is inclined relative to the handling device at a predetermined angle, a locking pin can not be inserted into a corresponding socket of the docking device (FIG. 1 a, FIG. 1 b). In this case, you must then manually assist in aligning and merging the handling device and test head. Even at low tilt angle of the test head over the handling device, it is no longer possible to introduce a locking pin in the locking unit, for example, as an edge of the test head contacted the handling device without a locking pin has entered into a recess of a locking unit.

In this position, the front end of the catch pin 51 is arranged at a distance from the stop plate 42.
- the fishing pin 51 may be externally, i. not by the movement means formed by the meshing engagement between the threaded tube 15 and the threaded sleeve 18, but by another device, e.g. an additional docking device a little further in the direction of the stop plate 42 are moved.
- the catch pin 51 is thus held with a movement play in the feed direction 62.
- FIGS. 9c, 10c show the state in which the catch pin 51 has traveled to the maximum extent into the merging device 1 and abuts against the stop plate 42 with its front end.
- the threaded tube 15 is rotated in the direction opposite to retraction.
- the pin holder 30 is moved in the direction of the cover plate 21.
- the ball cage 36 abuts against the cover plate 21.
- the spring element 27 rests against the cover plate 21 in such a way that the spring element 27 counteracts the further movement of the threaded sleeve with some bias.
- This spring force must be overcome in order to move the threaded sleeve 18 with the clamping portion 32 in the direction of the cover plate 21. Since the ball cage is already applied to the cover plate, the threaded sleeve 18 and thus the clamping portion 32 is moved relative to the ball cage 36, whereby the balls 37 are released. The balls 37 come out a bit radially outward from the ball inlet openings 40, whereby the engagement with the catch pin 51 is released. By the spring element 27, it is thus necessary to expend an additional force to release the latching engagement between the catch pin 51 and the merging device.
- the spring element forms a securing device, which enables the catch pin to be extended out of the merging device, but not released, before the spring force of the spring element 27 is overcome. During operation, it may be sufficient for maintenance work that the catch pin is extended out of the merging device but not released. Due to the additional force required to release the connection, it is possible to specifically approach a deployed but not disengaged position.
- a further securing device can be provided which reliably and reliably prevents unintentional unlatching of the catch pin from the latching device.
- the securing device can be designed in such a way that a securing pin 65 extending in the axial direction is provided on the side of the stop plate 42 facing the base plate 28.
- the locking pin 65 extends through a central opening in the base plate 28.
- the locking pin 65 has an annular groove 66 at its end remote from the pin receptacle 30.
- the annular groove 66 is stepped with its edge remote from the pin receptacle 30 and with its edge facing the pin receptacle 30 as a sliding bevel 67.
- a tubular housing 68 is arranged, in which the locking pin 68 retracts when a catch pin 51 is retracted.
- a spring pin 69 is disposed transversely to the longitudinal axis 61 on the housing 68 and spring-loaded such that it presses with its end face against the lateral surface of the locking pin 65.
- the securing device can also be configured such that plate springs 70 are provided instead of the spring element 27, which are arranged on the end face of the threaded sleeve 18 facing the cover plate.
- the disc springs are fastened by means of screws to the threaded sleeve 18.
- the threaded tube receiving plate 14 has recesses into which the screws can retract with their heads, but not the disc springs fit into the recesses.
- the disc springs must be compressed as well as the spring elements 27 to allow a relative movement between the threaded sleeve 18 and the ball cage 36.
- the disc springs 70 effect at low height a large spring force, which must be overcome to release the locking connection.
- the catch pin 51 is held in the retracted position with play in the axial direction. Only when externally acting on the catch pin 51, he proposes with its front end to the stop plate 42 (Fig. 9c, 10c). These embodiments are intended to cooperate with another docking device with which the final position of the handling device and the test head is fixed and fixed. Therefore, the merging device may be formed with a considerable play in the axial direction and / or transversely to the axial direction as compared to a docking device.
- the merging device is preferably combined with a docking device according to DE 102 16 003 B4. DE 102 16 003 B4 is hereby incorporated by reference.
- the retracted position of the catch pin is formed substantially free of play.
- a cone-shaped stop can be formed on the catch pin, which stop is designed to fit the first or second conical section of the insertion opening 6.
- the stopper may also cooperate with the end face of the insertion opening 6 or it may be arranged on the base plate 28 in the direction of the cover plate 21 facing stop pins which can pass through corresponding openings in the stop plate 42 and to which the catch pin in the retracted position shown in FIG 9b, 10b with its front side strikes.
- FIG. 12 schematically shows a fastening plate 4 with four joining devices 1 according to the invention, which are each arranged in the corner region of the mounting plate 4, which is approximately rectangular in plan view.
- a catch pin 51 is inserted into each of the merging devices 1 respectively.
- a toothed belt 71 is provided, which is designed as an endless toothed belt and rotates at the edge region of the mounting plate 4.
- the toothed belt is guided by guide rollers 72.
- the timing belt 71 is engaged with a drive gear 73.
- the drive gear 73 is coupled to a hand wheel 74, with which the drive wheel 73 can be rotated manually, so that the toothed belt 71 is set in motion.
- the toothed belt 71 is in meshing engagement with the rotary flanges 13 of the merging devices 1. Since all the merging devices 1 are coupled to the same toothed belt 71, they are operated synchronously. This causes the tucking pins 51 to retract or extend synchronously. Only a merging device 1 is formed with a securing device with a locking pin 65 (in Figure 12, the corresponding housing 68 can be seen). To secure the release of the latching connection, a single securing device is sufficient, since all the merging devices 1 are actuated synchronously.
- a circulating endless chain can also be provided.
- a motor electric stepper motor, hydraulic motor, etc.
- the attachment plate 4 is designed to be attached to a test head 2 (FIG. 13a).
- an interface module 75 which has spring contact pins (not shown) for contacting the contact points of the respective test specimens, is shown schematically in a roughly simplified manner.
- the interface unit 75 can preferably be inserted into the test head 2 by means of a drawer module, as can be seen, for example, from JP0959730A, US2003 / 0194821 A1 or EP1495339B1 or DE102012103893, and can be moved out with this drawer module for easy replacement.
- a composite plate 76 is shown, which has four eyelets 77, to each of which a catch pin 51 by means of a quick-release mechanism can be releasably or coupled fastened.
- the composite plate 76 is formed to be attached to a manipulator 3. Both the mounting plate 4 and the composite plate 76 are formed approximately rectangular in the top view and have a central large-area opening. They thus form a rectangular frame.
- a system according to the invention for merging a first device consisting of a handler or a tester with a second device consisting of an electronic component test head preferably comprises a handling device, a test head attached to a movable manipulator and at least one inventive merging device and a corresponding one catching pin.
- the entire process of merging and detaching the test head and manipulator can be performed by a single person.
- the manipulator takes the weight of the test head and in that at least one catch pin is provided, the test head only has to be roughly positioned in order to be attracted and "precisely positioned" by the catch device of the merging device.
- the linear displacement device is designed as a threaded sleeve with an internal thread, which engages in a corresponding outer thread of the threaded sleeve.
- the linear displacement device 50 may also be a screw or gear drive, such as a threaded rod which is offset by a drive in a rotational movement and thereby causes a displacement of the latching device, or be a hydraulic or a pneumatic piston.
- Thread tube receiving plate 54 Thread tube receiving plate 54.
- Linear sliding device Threaded tube 55.
