Definitions

• the invention relates to a device for Monta ⁇ ge of contact parts with attached lines in k S tec erge h äusen according to the preamble of the patent claim,
• a device according to the preamble of patent claim 1 is known for example from DE-OS 27 40 377.
• This known device is a so-called rigidly linked system, ie the gripper, the holder for the connector housing and thus the connector housing as well as the other functional elements are in a rigid relationship, which is given by the geometry of the device.
• This known device thus does not allow the flexible assembly of plug parts or contact parts in any plug housing.
• the invention has for its object to provide a device for mounting contact parts with cables attached to them in connector housings, which allows flexible and automatic assembly of any connector housings, in particular in connection with an industrial robot or a handling unit.
• the device for assembling contact parts with cables attached to them in plug housings has a base part which is at least in the joining or.
• the direction of insertion can be positioned relative to the nominal position of the connector housing. This positioning can be done by a separate drive, but preferably according to claim 4 by a handling or. Positioning device and in particular an industrial robot.
• the gripper is fastened to this base part by means of elements which are elastic at least in one plane perpendicular to the joining direction, so that the gripper is elastically suspended in the plane perpendicular to the joining direction.
• a vibration exciter (vibrator) generates vibrations of the gripper in the plane perpendicular to the joining direction relative to the base part.
• This structure of the device according to the invention allows the following mode of operation:
• the device flanged to an industrial robot is guided by it in front of the opening of the corresponding connector housing to be equipped; the vibration exciter is then activated, so that the gripper with the line gripped therein, together with the contact part, executes vibrations in the plane perpendicular to the joining direction. These vibrations can compensate for any tolerances that may occur between the contact part and the connector housing in the subsequent joining process. To do this, the industrial robot moves at a slower rate. Speed in the direction of the opening of the connector housing ⁇ and thus engages the contact part in the connector housing.
• a simple parallel jaw gripper can be used as the gripper (claim 5).
• the jaws of the gripper can grip the contact part, in particular in the crimping area; it is advantageous here if the jaws of the gripper are adapted to the shape of the contact part in the crimping area, so that a pre-centered gripping of the contact part is possible not only with regard to the position but also with regard to the rotational orientation. This provides a particularly good spatial relationship between the contact part and the axes of the handling device.
• the jaws of the gripper take the line. In this case, no special adaptation of the gripper shape is necessary, but a special design of the gripper jaws also enables the cable to be gripped precentered (not against rotation). By gripping the line, the vibrations which the contact part carries out are substantially greater than the vibrations of the gripper, so that particularly large tolerances can also be compensated for.
• the development characterized in claim 2 makes it possible to check whether the contact part is securely engaged in the connector housing.
• the industrial robot moves in the opposite direction after the contact part has been inserted into the plug housing. If the contact part is snapped into the connector housing, the two parts of the base part move against each other. If, on the other hand, the contact part is not properly engaged, there is no displacement of the two parts of the base part against the joining direction when the industrial robot is moved.
• a sensor that detects the movements of the two parts of the base part against each other (claim 3), for example a potentiometer connected in parallel, can be used to determine whether the joining process has ended properly with the engagement of the contact part in the plug housing.
• FIG. 1 a and 1 b show a side view and a front view of a device according to the invention
• 3 a to 3 c show the workflow of a further embodiment of the device according to the invention.
• the device for mounting contact parts shown in FIGS. 1 a and 1 b has a base part 1, with which it can be flanged to a handling device, not shown, for example an industrial robot or the like.
• the base part is formed in two parts and consists of the actual flange 11 and a part 12 which is guided in a linearly displaceable manner relative to the part 11 by means of a guide 2 against the force of a spring 21.
• a plate 4 is fastened to the part 12 by means of elastic elements 3. On the plate 4, a vibration exciter or a vibrator 5 is attached, which the plate 4 to
• the plate 4 is at "a Parallelbackengrei he fastened 6 is formed so that the may take a not shown in Fig. 1 contact part in the crimping region or on the line.
• the Paralllelbacken can be adapted to the gripper design of Crimp Siemens ⁇ or several tines 61 which pre-center the cable when picking it up.
• FIGS. 2 and 3 show the embodiment shown in FIG. 1 in several working positions
• FIG. 3 shows a slightly different embodiment in which a plurality of linear guides 2 are present.
• a further difference between the embodiment shown in FIGS. 1 and 2 and the embodiment shown in FIG. 3 is that the parts 11 and 12 are not positively connected to one another during the joining movement, but against the force of the springs on the Linear guides are slidably mounted so that the joining process is "elastic".
• the device according to the invention grasps a contact part 16 provided in a preparation station 15.
• the contact part is gripped in the crimp area, while in the version according to FIG. 3 it is gripped on the line.
• the jaws of the parallel jaw gripper consist of several fork-like parts or have tines 61 which are adapted, for example, to the shape of the crimping area, not only is a good longitudinal guidance of the cable achieved, but also a centering in the center of the gripper.
• Part b shows that the industrial robot moves the device with the pre-assembled cable in front of the opening of the connector housing.
• the vibration exciter is then activated. Due to the vibrations of the contact part, it automatically centers itself in the opening of the connector housing. Particularly when the contact part is gripped on the line, large vibration amplitudes are reached at the tip of the contact part, since the cable also vibrates as a limp part, so that even large positioning errors can be compensated for.
• the industrial robot moves the device in the opposite direction (partial image c).
• the part 12 slides on the linear guide 2 against the direction of travel when the joining process has been carried out properly.
• a sensor for example a potentiometer, a proximity switch or the like, can be connected, which detects whether a relative movement occurs between the parts 11 and 12. If this is not the case, it means that the contact part in the plug housing is not engaged.
• the device according to the invention is used in the assembly of any size plug housing with plug parts and contact parts by means of flexible assembly.
