Definitions

  • the invention relates to a shaping device for shaping a component carrier tape comprising component pockets from a raw tape.
  • Component carrier tapes are used to transport electronic components, for example memory chips, chips with integrated circuits, resistors, capacitors, etc. from the manufacturer of the components to the processor of the components, who assembles the components into new products.
  • a component comprises Carrier tape a variety of pockets that are arranged next to each other on the tape along its length and serve as receptacles for the components.
  • the component carrier tape typically consists of a thermoplastic material in which the pockets are formed. Different shaping devices are available for shaping the pockets when producing the component carrier tape from a raw tape.
  • the raw strip is first heated and then passed over a molding wheel that has depressions. Using a nozzle, the heated strip is pressed into the mold recesses of the mold wheel using compressed air. At the same time, the depressions of the molding wheel are often evacuated, so that the vacuum created thereby also pulls the warm raw strip into the mold. When the belt cools, the pockets formed in this way solidify.
  • the pockets are formed in a continuous sequence in rotary molding devices, the pockets are formed in a cyclical process sequence in press-forming devices.
  • Molding devices of this type comprise a molding tool with a stamp and a die, between which the previously heated raw strip is introduced in a first step, the component carrier strip molded in the previous cycle being removed from the molding tool at the same time. Then the mold is closed in the next step, whereby the pockets are pressed into the raw strip. Then the cycle repeats. When the band cools down, the shaped pockets solidify.
  • a press molding device for producing component carrier tape in which a molding tool is used to shape the pockets, is described, for example, in EP 0 809 925.
  • a machine for producing component carrier strip can process a certain throughput of raw strip per hour.
  • the production of component carrier tape can be increased by either increasing the number of machines or the throughput of the machines.
  • State-of-the-art machines with molding wheels or molding tools for shaping the pockets in the component carrier belt create a throughput of up to approximately 340 m of belt per hour.
  • a shaping device for forming component carrier strips comprising raw material strips from raw strip
  • the mold imparts a closing pressure when pressing.
  • a closing device for supplying the closing pressure to the forming tool and an opening device acting at least indirectly on the forming tool for opening the forming tool are connected to the forming tool.
  • a transport device serves to transport the raw strip to be processed and the finished component carrier strip into or out of the molding tool.
  • the molding device is characterized in that the closing device for generating the closing pressure comprises a compression spring and the opening device is designed to open the molding tool against the closing pressure.
  • the invention is based on the following considerations: With the form wheel, only relatively small bandwidths can be processed and only relatively small pockets can be produced. Large bags are therefore made by hot pressing using molding tools.
  • the maximum possible belt speed is determined on the one hand by the number of possible strokes of the molding tool and the number of pockets produced per stroke.
  • the number of pockets that can be formed per stroke in turn depends on the pocket size. Since a certain force is required to form a pocket, only a certain number of pockets can be formed with a certain pressing force of the molding tool, which pockets take up a certain length of the band.
  • the claimed tape length is called the index length.
  • index lengths of 56 mm are common, for large pockets index lengths of 144 mm per stroke.
  • the machines according to the prior art require approximately 1.5 seconds, which, for example with an index length of 144 mm per stroke, leads to a processing speed (belt speed) of approximately 340 m / h.
  • a large closing force can be generated, which enables a high acceleration of the molding tool when closing and thus a large number of strokes per hour.
  • the large closing force allows many component pockets to be formed with one closing operation, so that the molding tool can be equipped with many stamps over a long index length. Both the high acceleration of the molding tool and the many stamps make it possible to increase the processing speed when forming the pockets.
  • the molding tool comprises a stamp and a die, to which a separate locking device is connected at least indirectly, so that the stamp and the die can exert different forces on the raw strip when the component pockets are formed.
  • the compression spring of the closing device can be designed as a pneumatic spring.
  • the pneumatic spring has less mass than other springs, for example a spiral or leaf or torsion spring, so that the acceleration of the mold when opening and closing and thus the number of strokes per hour can be increased further. Belt speeds of 700 m / h or more can be achieved in this way.
  • the pneumatic spring comprises a compressed air bellows to which compressed air is applied.
  • This embodiment can be designed with particularly low mass. It also facilitates access to the working area of the mold, for example for maintenance purposes or for changing the die and stamp. By venting the bellows, for which e.g. If a ventilation device is provided, the closing force can be reduced, so that the mold can be opened without great effort.
  • Adjusting the compressed air pressure enables the closing force of the closing device to be easily adjusted, as a result of which the shaping device easily meets changing requirements, such as the thickness of the band or the dimensions of the component pockets to be molded can be adjusted.
  • the opening device comprises a shaft and a cam disk arranged on the shaft and driven by it.
  • the driven cam disk enables the mold to be opened cyclically against the closing force of the closing device in a simple manner.
  • a separate cam wheel can be assigned to the punch and the die, which means that different movements for the punch and die can be realized.
  • the shaping device is characterized in that the shaping tool comprises a heating device for heating the raw strip and / or a punching device for creating a control hole in the bottom of the component pockets.
  • the heating enables the component bags to be hot-pressed when the component carrier is being manufactured. gerbandes, the control hole when using the finished component carrier tape later, the control of the component pockets when filling or emptying.
  • the heating device and / or the perforating device can be implemented in separate, cyclically closing and opening tools, the tools imparting a closing pressure.
  • Each tool is equipped with a closing device for supplying the closing pressure and an opening device for opening the tool, the closing device comprising a compression spring for generating the closing pressure and the opening device being designed to open the mold against the closing pressure.
  • the separate design of the tools makes it possible to assign an individual closing pressure to each tool.
  • the wear pressure of the heating tool can, for example, be lower than that of the molding tool.
  • the component carrier tape is usually not yet completely cold again at the time of the perforation.
  • the remaining heat can lead to complications when forming the control hole.
  • the omission of that area of the raw strip in which the control hole will be formed later helps to avoid these complications. It is therefore particularly advantageous if the heating device is designed in such a way that it does not heat that area of the raw strip that forms the bottom area of the component pocket in the finished component carrier strip into which the punching device makes the control hole.
  • the molding device has a synchronization device for synchronizing the transport device with the cyclical opening and closing of the molding tool, so that the work processes of the molding device run as synchronously as possible.

Un dispositif de transport (5, 7) achemine la bande vierge (2) à usiner et la bande support (1) pour composants réalisée vers l'outil de formage (9) et hors de celui-ci. Le dispositif d'usinage est caractérisé en ce que le dispositif de fermeture (11) est doté d'un ressort de pression (11) pour générer la pression de fermeture, le dispositif d'ouverture (13, 15) étant conçu pour ouvrir l'outil de formage (9) dans un mouvement antagoniste à la force de fermeture.
