- a segment 61 "of the guide 61 is provided on the belt station 1 3 ', specifically on a slide 68 which is movable in the vertical direction and is moved via a control or rocker arm 69 by a central camshaft 70 which extends over the extends the entire length of the machine, drives still further stations of the machine and is synchronized with the drive for that of the steel belt 15.
- the slide 61 is the segment 61 "of the guide 61 and also an upper one, which bears against the top of the head 9a and in the slot 60 engaging plunger element 71 moves up and down.
- the segment 61 " is preferably provided on the slide 68 and the plunger 71 is sprung, so that the plunger 71 is moved downward when the segment 61" is moved downward by the action of the spring and follows the segment 61 "when it is moved upwards.
- a channel 72 is provided in the plunger 71, which forms the continuation of the channel 64 in the vacuum holder 9a located at the belt station 1 3 '.
- the two channels 64 and 72 are part of a light path between a light-emitting element 73 (for example an IR light-emitting diode) and a light detector 64.
- the element 73 is located below the path of movement of the belt 67 in such a way that, in the case of a cup 66 and vacuum holder 9a provided at the belt station 1 3 ', the axis of the light beam emerging from the element 73 is coaxial with the axes the channels 64 and 72 is located and this light beam can pass through an opening 75 in the bottom of the respective well 66.
- the light detector 74 is located at the upper end of the plunger 71. As long as there is a component 2 on the vacuum holder 9a, the light path is interrupted.
- the light emitted by the element 73 can strike the element 74. With these two signals it is possible to monitor the introduction of the components 2 into the belt 67 to rule out errors.
- monitoring section formed by the elements 73 and 74 can also be provided in other areas of the transport section 8 or 8a.
- FIG. 14 shows, as a further possible embodiment, in a representation similar to FIG. 9, a feed unit 5a for the lead frame 6a, the associated clearance and positioning device 7a and the subsequent transfer path 39.
- the lead frame 6a is designed in such a way that the components 2 are provided there in five rows in the lead frame longitudinal direction or feed direction V, i.e. Connect five components 2 to each other transversely to the longitudinal direction of the lead frame.
- the punching and positioning device 7a has, similarly to the punching device 7, a punching tool with which the components 2 located at the cutting station or at the cutting position 80 are punched out of the step frame 6a, which is moved forward step by step, again from below with a corresponding punching tool.
- the peculiarity is that in each work step all components 2 of two groups 81 and 82, which are adjacent to one another in the feed direction V and run transversely to the feed direction V, are simultaneously punched out, that is to say a total of ten components 2 simultaneously in the illustrated embodiment.
- each transfer device 83 and 84 has a multiplicity of vacuum holders 35, that is to say five vacuum holders 35 each in the illustrated embodiment, which are arranged in a line perpendicular to the longitudinal extension or feed direction V of the lead frame 6, namely at an axial distance which is equal to that Is the distance which the components 2 in each group 81 and 82 have from one another.
- the vacuum holders 35 are provided on a slide 85 (transfer device 83) or on a slide 86 (transfer device 84).
- the distance X is greater than the distance that each component 2 from group 81 has from component 2 from group 82 in the longitudinal direction of the lead frame.
- the vacuum holders 35 of the transfer devices 83 and 84 are each arranged above a receiving area 46 of the rows A 'and B'.
- the carriage 86 of the transfer device 84 is moved linearly in the illustrated embodiment, that is to say in the plane parallel to the lead frame 6a and perpendicular to the feed direction V, in such a way that in the transfer position of the transfer device 84 the components held on the vacuum holders 35 of this transfer device 2 are placed on the free receiving areas of row A 'of the transfer line 39.
- the advantage of the embodiment in FIG. 14 includes in that a transfer of a plurality of components 2, i.e. in the illustrated embodiment of a total of ten components 2 is possible in one working stroke from the lead frame 6a to the transfer path 39 and so, inter alia, Even at a given working speed of the feed unit 5a, high performance can be achieved.
- the feed unit 5a is particularly suitable for processing lead frames 6a which have a large number of component rows.
- Such lead frames have the advantage, among other things, that considerable material savings can be achieved in relation to the number of components 2, specifically with regard to the material of the lead frame and, above all, also with respect to that for the housing of components 2 in the so-called "Molding", ie material required for the shapes of the housings of the components 2.
- a lead frame with a large number of component rows in the longitudinal direction also offers the advantage of improved quality, in particular also in the case of "molding".
