Definitions

  • the invention relates to a method for approaching a predetermined position of a moving in a direction of travel carrier tape and a starting device.
  • a starting device For the processing of components on a carrier tape or for storing components on the carrier tape usually a starting device is used, which can approach certain positions on the carrier tape by means of a traversing head.
  • a predetermined position is approached by the traversing head and the carrier tape is stopped at the predetermined position at the time of performing the operation, so that the traversing head is the predetermined one Operation during standstill of the carrier tape can perform.
  • this has the disadvantage that the stopping and the restarting of the carrier tape is very time-consuming, whereby the throughput of the overall arrangement is reduced.

  • the traversing head can be moved to approach the predetermined position in a straight line, in an arc or in a rotating manner.
  • the traversing head can deposit a component at the position, the component preferably being picked up by the traversing head before the predetermined position is approached.
  • a plurality of components are received and the plurality of components successively deposited by starting at a plurality of predetermined positions on the carrier tape, wherein each of the components for settling at the corresponding predetermined position at a speed in the direction of travel of the carrier tape is moved, the Traversing speed of the carrier tape corresponds.
  • a component is processed, in particular bonded, as a process at the position.
  • a starting device for approaching a predetermined position of a carrier strip which moves continuously in a travel direction.
  • the starting device comprises the carrier tape, a traversing head, for performing an operation at the predetermined position on the moving carrier tape.
  • the traversing head can be moved in a transverse direction, which runs transversely to the direction of travel, and in the traversing direction, the transport device being controlled by means of a control device, so that the traversing head moves to the predetermined position at a speed in the direction of the traversing direction which essentially corresponds to the travel speed of the carrier belt.
  • control device controls the transport device so that the traversing head for approaching the predetermined position in the transverse direction with a constant or variable transverse speed is moved, or that in carrying out the operation, the transverse speed in the transverse direction is substantially zero.

  • FIG. 1 shows an overall system 1 with a starting device for approaching a position on a carrier belt 2 moving in a travel direction.
  • the starting device has a carriage 3.
  • a traversing head 4 is movably arranged on the longitudinal axis of the carriage 3 so that the traversing head 4 can be moved along the longitudinal axis of the carriage 3.
  • the carriage 3 itself can be moved along a rail 5 in a direction transverse to the longitudinal axis of the carriage 3, wherein the direction of the rail 5 preferably corresponds to the direction of travel.
  • the carriage 3 and the rail 5 are parts of a transport device, with which the traversing head 4 can be moved in an x- and a y-direction in the plane of the carrier tape 2.
  • the transport device is controlled by a control unit 6, so that the starting device processed by means of the traversing head 4 at the predetermined position of the carrier tape 2 specific operations.
  • the carrier tape is conveyed by a conveyor belt unit. moves, on which the carrier tape is at least partially stored, so that there is a support surface of the carrier tape 2 in the starting region of the traversing head 4.
  • Such a starting device is able to equip the carrier tape 2 with components, in particular electronic components such as capacitors, resistors, ICs and the like, at predetermined positions, e.g. insert into corresponding recesses of the carrier tape 2. Furthermore, such a starting device can be used to machine components which are arranged at predetermined positions on the carrier tape 2 in a certain way.
  • the traversing head 4 could be provided with corresponding processing units (not shown), such as with a bonding unit which attaches bonding wires to components at predetermined positions, or with another tool for machining the component.
  • the starting device is provided for loading the carrier tape 2 with components
  • the traversing head 4 can receive one or more of the components provided there and transport them in a subsequent traversing step to the corresponding predetermined position on the carrier belt and place them there.
  • the carrier tape 2 is moved by a drive device 8 at a continuous travel speed in the x direction.
  • a drive device 8 For carrying out the process at the predetermined position of the carrier tape 2, in particular for depositing a picked-up component or for processing a component located there, it is necessary for the relative speed between the carrier tape 2 and the traversing head 4 to be as low as possible or the same Zero is, so that a positionally accurate settling of the component or a precise machining of the component at the predetermined position is possible. For this reason, at least at the time of carrying out the process, the carriage 3 is moved over the rail 5 with the travel speed of the carrier tape 2 in the x direction, so that the relative speed between the travel head 4 and the carrier tape 2 becomes zero.
  • the lateral velocity which is in a transverse direction transverse to the x-direction, ie in the y-direction, is equal to zero, to exclude any relative movement between the traversing head 4 and the carrier tape 2.
  • Crossing speed is reduced to zero and after performing the predetermined operation, the transverse movement of the traversing head 4 is resumed to move to the next corresponding position.
  • the traversing head can be controlled in many ways and the overall movement of the traversing head 4 can be arcuate, rectilinear or rotational.
  • FIG. 2 shows possible travel paths of the traversing head for approaching a plurality of predetermined positions (indicated by boxes) on the carrier belt 2.
  • the speed v of the carrier tape 2 is constant in the embodiment described above, but it can also be provided a variable speed, but a complete stop of the carrier tape 2 to perform the operation should be avoided to special tensile loads on the carrier tape 2 and a fürsatzredu - To avoid ornamentation due to the stopping and restarting the carrier tape 2.
  • the carrier tape may be transported at a lower speed than the traversing speed v between the operations, the speed of the traversing head 4 in the x direction controlled by the control means 6 corresponding to the change in speed of the traverse head Carrier tape 2 is adjusted.
  • Another advantage is that an additional transport time of the traversing head in the x direction is eliminated since this movement takes place simultaneously with the feed movement of the traversing head, ie that the traversing head 4 follows the movement in the x direction of the carrier belt 2. Furthermore, the working field of the traversing head in the x-direction remains constant even at different distances between the predetermined positions, since the path in the x-direction can be determined via the web speed. It follows that the size of the working field in the x-direction or the path in the x-direction of the traversing head can be influenced and controlled by the web speed.
  • Clock drive of the carrier tape 2 can now be a friction drive for the carrier tape 2 are used, and it results in a lighter leadership of the carrier tape 2 and its orientation by the continuous movement.
  • the predetermined positions on the carrier tape 2 can be arbitrarily arranged, which was previously not the case during clocking due to the reduced number of holding positions of the carrier tape due to the maximization of the throughput.
  • the distance z indicates the distance between die and die.
  • N indicates the number of rows.
  • S is the way of the tape during a bar.
