Punching module for carrier tape

Abstract

This invention relates to a punching module for carrier tape, comprising a base, a first mold, a second mold, and a punch holder. The two molds are positioned on the base, forming a channel between them. The second mold is located between the first mold and the base and has a plurality of discharge channels. Each discharge channel has a punch section, a tapering section, and a discharge section connected in sequence. The punch section is connected to the bottom of the channel, and the tapering section tapers from the punch section toward the discharge section. The punch holder has a plurality of punches and can move relative to the base, allowing the punches to pass through the first mold and extend into the discharge channel. The diameter of the punch is smaller than the aperture of the punch section but larger than the aperture at the connection between the tapering section and the discharge section. This allows the material to be intercepted as a guide and load control, reducing offset and shortening the stroke during subsequent punching, thus achieving repeatable high-precision punching.

Claims

1. A punching module for a carrier tape, comprising: a base; a first mold positioned on the base; a second mold positioned on the base and located between the base and the first mold, a channel forming between the second mold and the first mold, the second mold having a plurality of discharge channels communicating with the channel, and having a punch section, a tapering section and a discharge section sequentially connected thereto, the punch section being connected to the bottom of the channel, the tapering section tapering from the punch section toward the discharge section; and a punch holder disposed on the base and having a plurality of punches, the punch holder being movable relative to the base, such that each punch passes through the first mold and the channel and extends into a corresponding one of the discharge channels; wherein... The diameter of each punch is smaller than the aperture of the corresponding punch section of the discharge channel, and larger than the aperture at the connection between the tapered section and the discharge section of the corresponding discharge channel.

2. The punching module for carrier tape as described in claim 1, wherein at least a portion of the discharge section gradually expands away from the tapering section.

3. The punching module for carrier tape as described in claim 1, wherein the second mold comprises a mold body and a plurality of inserts inserted into the mold body, the punch sections of the plurality of discharge channels are formed on the mold body, and the tapered section and discharge section of each discharge channel are formed on one of the inserts.

4. The punching module for carrier tape as described in claim 1, wherein the plurality of punches have different diameters and the plurality of drop channels have different apertures to correspond to the plurality of punches respectively.

5. A punching module for a carrier belt as described in any one of claims 1 to 4, wherein the first mold is provided with a plurality of positioning holes, each positioning hole communicating with the channel and being linearly opposite to one of the corresponding drop channels, and each punch passing through the first mold passing through one of the corresponding positioning holes.

6. A punching module for a carrier tape as described in any one of claims 1 to 4, wherein the base is provided with a plurality of spaced-apart pins, each pin passing through the second mold and inserted into the first mold, thereby positioning the first mold and the second mold relative to the base.
