Description

Carrier tape other sub-plate of mold device the combination structure}

The present invention relates to a carrier tape perforated mold subsidiary plate coupling structure, and more particularly, a carrier tape perforated to improve workability and productability by being able to easily and firmly detach and mount a stripper mounted on a stripper holder. It relates to a mold auxiliary plate coupling structure.

In general, in a device having a deployment effect transistor (FET) and an electronic component such as a chip component such as a resistor or a capacitor, there is a reduction in the weight, size of the product and a large increase in operating frequency. It has been made lighter, thinner and shorter.

These small electronic components are automatically inserted into the circuit board. In general, in order to continuously supply the electronic components to the automatic insertion device for automatically inserting the electronic components on the circuit board, the electronic components are regularly spaced to accommodate the electronic components. An electronic component carrier tape having rectangular holes, that is, receiving holes, is used.

In addition to the above-mentioned accommodation hole, the carrier tape made of paper wound around a circular reel has a circular transfer hole, that is, a transfer hole, for transferring the carrier tape at an accurate pitch.

When machining the conveying hole or the receiving hole on the carrier tape again, the cut material is attached to the processing end of the punch, which may cause machining defects. Also, because the punch diameter is small, the punches may sometimes shake. In this case, the punch hits the upper surface of the carrier tape and the lower mold while the punch is not correctly seated in the mold through-hole of the lower mold, so that the punch and the lower mold collide with each other, thereby causing a relatively expensive punch or lower mold to be damaged.

In order to improve the durability of the lower mold from the punching of the punch, a mold apparatus of a type for seating the guide plate on the upper surface of the lower mold is used to solve the above problem, but the end of the punch and the guide plate The cost of replacing the guide plate, which is relatively expensive due to abrasion due to friction with the guide hole inner circumferential wall, is disadvantageous. In order to replace the guide plate itself, the lower mold and the guide plate of the mold apparatus are dismantled and There was a problem of low labor productivity due to the complicated process of assembling.

Implementation of carrier tape perforated mold auxiliary plate which can improve durability of relatively expensive guide plate by replacing the auxiliary plate worn by frictional heat due to the vertical movement of the punch by fixing the auxiliary plate on the upper surface of the guide plate to solve the above problems. This is required.
