Description

  The present invention relates to a processing device such as circuit board etching and cleaning, and more particularly to a full flat circuit board processing and transporting device for transporting a circuit board for performing operations such as etching and cleaning.

Conventional full flat type processing and transporting equipment used for etching, cleaning, etc. of circuit boards usually puts a circuit board to be processed directly on it. That is, the circuit board is interlocked by a plurality of roller shafts placed on the processing and transporting device and arranged at intervals.
In this way, the circuit board can be transported forward without stopping by the pre-installed horizontal line, and when the circuit board passes through the horizontal line, processing work such as etching or cleaning is performed on the circuit board. .

  In the above-described conventional full-flat type processing and transporting device, when the circuit board is interlocked, the circuit board is pushed forward and transported forward by the plurality of rollers installed on the plurality of roller shafts.

However, since the circuit board itself has a certain weight, and there is inevitably a distance between the roller shafts, the circuit board surface is completely leveled during the entire circuit board transportation process. Can not hold on.
For this reason, during transportation, the front edge of the circuit board is affected by gravity, and a situation in which the circuit board hangs slightly downward between the rollers tends to occur.

Furthermore, since the rear roller continues to push the circuit board forward without stopping, a situation in which the edge of the circuit board is caught on the roller is likely to occur, and this may cause a crease.
Further, in serious cases, the circuit board edge is sandwiched between two rollers, and even a situation occurs where the planned horizontal transportation route is left.
This not only prevents the circuit board from being processed smoothly, but also may cause damage.
