BACKGROUND OF THE INVENTION [0002] The present invention relates to a solution for plugging in a plurality of inlet manifolds, in particular a transistor of pallet mold pallets, in a plastic housing.

Until now, the introduction of pallet lead-in sets has been done by hand using tweezers or preparations, or by means of a vacuum bead, which is disadvantageous because the suction surfaces of small types of transistors are very small. The mechanical insertion heads in the gripping movement have caused the corrugation of the inlet set, which is not negatively involved in setting on the centering pins, pallets, the pressing of the sets on these pins has not been performed. The pressing of the dowel sets must then be carried out additionally.

The above drawbacks are alleviated and the technical problem is solved by a feed stacker head, consisting essentially of a support beam on which the body is fixed. There is an opening in the body in which the piston is displaceable. The aperture is provided with an upper lid with an inlet and a lower lid. The suspension rod is mounted on the lower rod. The arms are pivotally mounted on the fork and are slidable by sliders mounted in the body. Lines are attached to the sliders, in which sprung readings are stored. Centered mandrels are mounted on holders mounted on the body. [0012] The set-up head of the invention is capable of automatically picking up the inlet sets, their stacking on the respective pallets and at the same time pressing them onto the centering pins of the pallet, which are usually made with an overlap with the center holes. The advantage is that the underlay device can be incorporated into automatic loading machines and assembly line handling units.

Figure 1 is a partial cross-sectional view of Figure 1, the cross-sectional view of Figure 2 is shown in Figure 2, and B is depicted in Figure 3; FIG. 1, FIG. 4 shows a pallet of the housing press, and FIG. 5 shows a plan view of a pair of transistor inlet files with slip-on jaws and centering pins.

The file insertion head comprises a support dock 3, on which the body 1 is fastened to the cradle 2. An opening 21 is formed in the body 1 in which the movable piston 4 is spring-loaded. The opening 21 is provided with an upper lid 7 formed by a pressure medium inlet and a lower lid 8. At the lower end of the piston rod S there is a fork 11 suspended by means of a spring 10 fixed to a washer 9 and an insert 14. There is a pivot on the fork 11 Sliders 15 are connected to the arms 12 by means of pins 13 connected in the body 1 by means of pins 13. The guides 16 are attached to the sliders 15 in which the jaws 17 are suspended by the spring 18. In the holders 19 mounted on the body 1, centering centers 20 are mounted, next to which the press rolls 25 are actuated.

The File Feeder Header function is as follows:

The perpendicular vertical movement of the headstocks 17 into the gaps between the outwardly oriented sets of inlets 26a is simultaneously slid into the center holes of the inlet sets 26 of the centering mandrel 20, thereby precisely defining the position of the inlet sets 26. By introducing the pressure medium through the upper lid 7 above the piston 4, this moves the free position, the jaw 17 extends through the spring 10, the arms 12, the slide 15 and the guide 16, thereby tensioning the thrusts, which is advantageous in terms of the undulation of the feed sets 26.

The head moves the sets of inlets 26 out of the clamping position by vertical misalignment, by means of the handling mechanism, the position 27 is moved over the stacker, on which the centering pins 28 of the head move vertically into the lower position of the inlet sets 26, the control system aborts the pressure above the piston 4, the jaws 17 are disengaged and the press roller 22, by means of the molding strips 25, pulls the sets of inlets 26 of the centering pins 20 and presses their center pins 28 of the pallet 27. The presser bar 22 returns to the initial position and the entire head returns to the upper and lower position and the entire cycle repeats. The deformation effect of the outlet 17 of the inlet manifolds 26, which are deformable, is eliminated by clamping over the spring 10 and the individual springs 18 with the subfloor 17, which also ensures a reliable clamping of the two independent sets of inlets 26.

The set-up head of the invention can be used in automatic loading machines for encapsulation of transistors into plastic sleeves in large-scale molds and in handling automated assembly lines of electronic components. By simply replacing the nozzles 17, the head can also be used to embed sets of integrated circuit inlets and other assembly operations of a similar nature.
