Definitions

  • the invention relates to a shaping device for producing a component carrier tape by forming component pockets in a raw tape.
  • Component carrier tapes are used to transfer 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 assembles new products to transport.
  • a component carrier tape comprises a plurality of pockets, which are arranged one behind the other on the tape over 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.
  • the heated strip is pressed into the mold recesses of the molding wheel by compressed air using a nozzle.
  • the depressions of the molding wheel are often evacuated, so that the vacuum created thereby also pulls the warm raw strip into the mold.
  • 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.
  • Such shaping devices comprise a shaping tool with a stamp and a die, between which the previously heated raw strip is introduced in a first step, the component carrier strip formed in the previous cycle being removed from the shaping 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-forming device for producing component carrier tape in which a molding tool for shaping the pockets is used. finds, is described for example in EP 0 809 925.
  • the molding tool comprises a stationary die, which is therefore not moved during the manufacturing process, and a movable stamp for shaping the component pockets.
  • 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.
  • the person skilled in the art therefore has the task of providing a device for shaping component carrier tape, with which higher tape speeds can be achieved.
  • the shaping device for producing a component carrier tape by forming component pockets in a raw tape comprises a molding tool with two half parts arranged above and below the continuous raw tape, wherein a first half part comprises a movably mounted die, which can be displaced in the direction of the raw strip or during the opening process away from the raw strip by means of a closing and opening device, and fixes the raw strip in the closed state of the molding tool and
  • a second half part comprises a movably mounted stamp which can be displaced in the direction of the raw strip or during the opening process away from the raw strip by means of a closing and opening device and which forms the component pockets in the fixed raw strip and
  • a transport device for transporting the raw strip to be machined and the finished component carrier strip in the opened state of the molding tool in and out of the molding tool.
  • the invention is based on the following considerations:
  • 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 need for a stroke according to the prior art, approx. 1.5 seconds, which, for example with an index length of 144 mm per stroke, leads to a processing speed (belt speed) of approx. 340 m / h.
  • the manufacturing process can be further accelerated with the molding device according to the invention, which comprises both a movable plunger and a movably mounted die.
  • the molding device according to the invention which comprises both a movable plunger and a movably mounted die.
  • particularly high closing forces can be transmitted via a movably mounted die.
  • a high clamping force allows the mold to accelerate quickly when closing and thus enables 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 forming tool and the many stamps make it possible to increase the processing speed when forming the pockets. There is no need for a conventional ejection device.
  • the punch and die are each connected to a separate locking device, so that the punch and the die can exert different forces on the raw strip when the component pockets are formed.
  • the closing and opening devices of the stamp and the die are at least indirectly operatively connected to one another, so that a coordination of the movements of the punch and die is possible during the production of the component pockets.
  • the movement sequences are coordinated such that the raw strip remains in its plane during the entire manufacturing process, that is to say is not moved relative to the components of the molding tool. This enables a particularly high level of precision to be achieved during the molding process, since slipping of the raw strip in the molding tool is avoided.
  • the closing device preferably comprises a compression spring, in particular a pneumatic spring.
  • the pneumatic spring has less mass than other springs, for example a spiral or leaf or torsion spring, as a result of which 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 venting device is provided, the closing force can be reduced, so that the molding tool 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 formed 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 opening devices of the stamp and the die are preferably connected to one another in an articulated manner. because the movement sequences of the components can be coordinated particularly easily.
  • stamp is arranged below the raw strip. In practice, this arrangement provides particularly precise results in the molding process.
  • a peripheral edge of the die forms a support for the longitudinal straps of the raw strip.
  • a work plate of the molding tool which has a cutout opening for the stamp, functions as a counter-support for the raw strip. This prevents the raw strip from slipping during the manufacturing process.
  • a fixing plate floating on the work plate via spring elements forms the counter-support. The slight play of the spring elements of approx. 0.2 to 0.3 mm allows. it compensates for differences in thickness in the raw strip and leads to a more even distribution of the applied compressive forces.
  • 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 producing a control hole in the bottom of the component pockets.
  • the heating enables the component bags to be hot-pressed when the component carrier tape is being manufactured, and the control hole when the finished component carrier tape is used later enables the component bags to be checked 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 being a compression spring for generating the Includes closing pressure and the opening device is 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 closing 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 such 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 synchronizing device for synchronizing the transport device with the cyclical opening and closing of the molding tool, the heating device and the punching device, so that the work processes of the molding device run as synchronously as possible.
  • the transport device can comprise a drive for imparting a gradual advance to the component carrier belt or the raw belt.
  • the synchronizing device can be implemented by a trigger arranged on the shaft to trigger the advance steps.
  • the shaping device has a cutting device, which is arranged downstream of the shaping tool and a transport direction of the raw or component carrier tape and is designed to divide the shaped component carrier tape in the longitudinal direction.
  • the molding tool is preferably designed det, at least two in the longitudinal direction of the component carrier tape side by side arranged component pockets into the component carrier band, so that at least two rows of component pockets arranged next to each other are created on the component carrier band.
  • the cutting device is preferably arranged relative to the molding tool in such a way that the cutting device divides the component carrier tape in the longitudinal direction between the component pockets formed next to one another. In this way, several component carrier tapes can be produced from one raw strip, so that the production of such component carrier tapes can take place particularly quickly and efficiently.
