Definitions

  • the invention b e describes a method for the automated assembly of a movable protective cover at a Magnet ⁇ tape cassette serving slider in the form of a made of an elastic material U-section with a longer and a shorter leg, to which of the arms plane towards the interior of the U Profiles projecting guide parts are provided, which are provided for the guide engagement in guide grooves which extend on both broad sides of the cassette in the direction of displacement of the slide and in which the guide parts are secured by the elastic forces of the material of the slide.
  • the invention also relates to a device for performing the method.
  • cassettes in question in particular tape cassettes
  • tape cassettes are mass-produced items which are produced in such large numbers that the lowest possible production effort must be sought for the slide valve and the means for attaching it to the cassette Slider designed in the manner of a U-shaped spring clip which, after spreading its legs, can be snapped into the cassette by its own elastic forces.
  • the object of the present invention is to show an assembly method which enables fully automatic slide assembly with the short cycle time of 50 or more assembly operations per minute required for mass production.
  • this object is achieved in a method of the type mentioned at the outset in that the slide is inserted into a workpiece holder and clamped in it by a pressure body resting on the outside of the slide back connecting the legs relative to one on the free leg end of the shorter one Leg acting clamp body is moved that the legs of the slide against the elastic forces of the material are spread apart by the clamp body transversely to the direction of action of the pressing force clamping the slide in the direction spreading the shorter leg away from the longer leg, while the longer leg is acted upon by a tensioning element acting on it with a force spreading it away from the shorter leg, and in that the spread legs of the slider are moved over the corresponding broad sides of the cassette into an insertion position in which the guide parts of the legs are aligned with the associated guide grooves of the cassette and can be snapped into the cassette by the elastic forces of the material of the slider, in that the limbs through relative movements between them and the clamping body and the clamping body are released.
  • the slide for the assembly process is clamped on the outside of its slide back and the clamping body generating the pressing force for clamping is simultaneously used for spreading the legs apart, i.e. is moved away from the longer leg of the slide during the spreading process, a perfect clamping and thus securing the position of the slide in the workpiece holder is achieved without the accessibility of the interior of the! J profile being impaired.
  • the slide can be easily moved over the cassette into the insertion position by a corresponding movement of the parts of the workpiece holder holding it.
  • a device for carrying out the method is characterized according to the invention by a) a cassette holder in which a magnetic tape cassette to be provided with a slide can be detachably fixed; b) a workpiece holder with a bearing surface for contacting the outside of the shorter leg of a slide; c) a clamping and spreading device provided on the workpiece receptacle for clamping the slide and for spreading the legs thereof apart from one another with cl) a pressure body resting on the outside of the slide back, which acts in the direction of a clamping body acting on the free end edge of the shorter leg is movable in order to generate a pressing force which clamps the slide back against the pressure body, c2) a clamping bar formed on the clamping body, which engages at the free end edge of the shorter leg in the interior of the U-profile, c3) a device for moving the clamping body in a transverse direction to the direction of action of the pressing force direction for spreading the shorter leg from the longer leg and with c4) a clamping body

  • the cassette 1 has the 1 and 9, a movable protective cover in the form of a slide 3, which is shown individually in FIGS. 2 and 3.
  • the slide 3 is made of thin, resilient stal sheet metal and has the shape of a U-profile section with a longer leg 5 and a shorter leg 7, which are connected by a profile web forming a slide back 9.
  • Fig. 1 shows the slide 3 in an open position, in the round openings 11 and 13 in the longer leg 5 are aligned with corresponding openings of the cassette 1.
  • Fig. 9 shows the slide 3 in the closed position.
  • a workpiece holder designated as a whole by 25, into which a slide 3 can be inserted by an automatic input unit of a known type (not shown) or an industrial robot has support rails which form support surfaces 27 on which the slide 3 with its shorter leg 7 can be placed when the slide 3 is entered in the feed direction indicated by an arrow 29 in FIG. 5.
  • the longer leg 5 is supported on a facing wedge surface 31 of a flat, elongated clamping wedge 33.
  • the slide 3 faces an associated contact surface 34 of a pressure body 35.
  • the edge of the slide 3 connecting the slide back 9 with the shorter leg 7 lies against an inclined surface 37 which is formed at the corresponding end of the contact surface 34 of the pressure body 35.
  • a plurality of cassette receptacles can be provided, for example, on a rotary indexing table in order to bring cassettes into the assembly position relative to the workpiece receptacle 25 in cycles in switching movements, the direction of which is indicated by an arrow 47 in FIG. 4.
