Definitions

  • the invention relates to a method for transporting printed circuit boards through drying systems in which the printed circuit boards are only held at opposite edges.
  • the invention further relates to a device for performing this method.
  • the object of the invention is to keep the coated surfaces of different plate formats and different plate thicknesses contact-free in the work surfaces during the entire transport route through the transport system.
  • This object is achieved in accordance with the method according to the invention essentially in that the holding arms of the plate holder are automatically adjusted to the respective width of the circuit boards before the circuit boards enter the drying system.
  • This is preferably carried out according to the invention in such a way that the printed circuit board width is queried automatically and the result of the polling is the setting of the.
  • Control arms of the plate holder controls.
  • the method according to the invention can practically be carried out with various types of devices.
  • a simple device of this type consists, for example, according to the invention in that the holding arms of the plate holder can be adjusted by means of threaded spindles. Instead of the threaded spindles, the holding arms can also be adjusted by actuating pressure medium such as pneumatic or hydraulic piston-cylinder devices.
  • the loading point of the circuit boards is usually horizontal. Between the holding arm adjustment point and the loading point is z. B. a certain number of plate holders. This number of board holders determines which board width must be queried so that the board and board holder are coordinated.
  • the holding arms can be designed in different profiles.
  • a lying [profile is z. B. selected for rigid circuit boards. The edge zones of such printed circuit boards are not coated.
  • a lying, diagonally open -Profile is suitable for printed circuit boards with an uncoated edge zone that is too small.
  • a profile with a clamping device is used for flexible printed circuit boards.
  • the invention is illustrated for example in a horizontal drying plant.
  • Fig. 1 shows a schematic side view of the drying plant
  • Fig. 2 shows a plan view of the inlet part of the drying system along the line AB of Fig. 1 on an enlarged scale.
  • the heatable horizontal drying system shown in FIG. 1 consists, for example, of an insulating jacket 1 in which there are several fans 2 which are driven by motors 3 and blow the heated air into the interior of the dryer via air channels 4.
  • a circulating transport system 5 is arranged inside the dryer 1. This consists of a left and a right transport chain 6, which run around sprockets 7 and 8. Angle plates 10 are attached to the chain links 9 of the chains 6 and carry the plate holders 11. The revolving chains 6 with the plate holders 11 are driven by an electric motor 12.
  • the circuit boards 13 to be dried are fed in according to FIG. 1 on the right-hand side, and the outlet thereof on the left-hand side of the dryer 1 in the direction of the arrows shown.
  • circulating conveyor belts 14 are provided, for example, which are driven by motors 15.
  • the conveyor belts 14 extend into the deflection areas of the plate holder 11. Outside the dryer jacket 1, the width of the printed circuit board 13 is determined. This can be done, for example, with the aid of sensors 16, which contactlessly scan the printed circuit boards 13, such as, for. B. photocells.
  • Each plate holder 11 consists, for example, of FIG. 2, of mutually opposite holding arms 17 with an angular profile, which hold the printed circuit boards 13 with their horizontal legs 17 '.
  • the holding arms 17 are mutually displaceable in the direction of the arrows.
  • This threaded spindle carries a driver 20 at one end, which can be detachably coupled with a left-hand or right-hand drive.
  • This drive device is arranged in a stationary manner in the dryer and is brought into engagement with the driver 20 in each case during the waiting times of the dryer cycles and released again after the holding arm 17 has been adjusted.
  • the threaded spindle 19 is rotatably mounted on both sides in the angle plates 10 of the transport chains 6.
  • a rotation of the holding arms 17 is prevented by the fact that the holding arms 17 can be displaced on a longitudinal guide 22 by means of sliding bushes 21, 21 '.
  • the holding arms 17 must be adjusted to the correspondingly smaller width 17', which is indicated in FIG. 2 with dash-dotted lines. This is done again with the help of the threaded spindle 19 in the manner described above. In the same way, the holding arms of the plate holder can be automatically adjusted to the PCBs that are brought up.
  • the device according to the invention works analogously to the description above.
