In the above industries, it is often necessary to use precision electronic components such as diodes and transistors. These electronic components have slender pins and need to pass the pins through the flexible circuit board or the rigid circuit board in advance during the assembly process. The holes are soldered to the pins and the circuit board to bond them. However, due to the requirements of product design regulations and the overall volume of the product, the gap between the holes and the pins is quite small, requiring manual assembly operations, which is time-consuming and expensive, and when the number of pins for a single electronic component increases , The difficulty of assembly operations will be even more improved.

To this end, one of the solutions is to cut the pins of the electronic components to form a sharp bevel shape. In this way, only the tip of the pins needs to be inserted into the holes during assembly to ensure that all the pins are uniform. It can be smoothly aligned with the hole and assembled smoothly, which not only improves the efficiency of assembly, but also makes the assembly work automated, which further saves time and cost. However, there is currently no machining module on the market that effectively performs the above-mentioned cutting operations, making this method unpopular.

On the other hand, the cutting member 220 is slidably disposed in the chute G and is formed with at least a lower cutting surface 222. In this embodiment, the lower cutting surface 222 and the upper cutting surface 110 are opposite to each other and have corresponding shapes, and the number is, for example, four. , Used to cut the stitch 21. Preferably, the cutting member 220 further has a side surface 224, wherein the side surface 224 is adjacent to the lower cutting surface 222 and includes a vertical portion 224a and at least one inclined portion 224b. In this embodiment, the number of inclined portions 224b is, for example, two. , Are respectively arranged at the upper and lower ends of the vertical portion 224a and inclined with respect to the vertical portion 224a, thereby facilitating the cutting operation, and can assist the cutting member 220 to discharge the cut pin 21 waste. The details of this part will be later Detailed in the article.

The following will describe in detail how to cut the pins 21 of the electronic component 2, please refer to FIGS. 8 to 11, where FIG. 8 is a schematic flowchart of an embodiment of a cutting method using the pin cutting module of FIG. 1, and FIG. 9 It is a front view schematic diagram of the pin cutting module of FIG. 1 when the pins of the electronic component are cut, FIG. 10 is a partial enlarged schematic view of the area X in FIG. 9, and FIG. 11 is a perspective schematic diagram of the electronic component of FIG. 3 after the pins are cut. To facilitate understanding, the upper mold 100 is presented in a transparent form in FIG. 10. The cutting method of this embodiment includes: arranging the electronic component 2 in the accommodating portion A and making the pins 21 pass through the pin holes H and protrude relative to the upper cutting surface 110 (step S01), and the cutting piece 220 is relative to the fixing piece 210 Sliding and cutting the stitch 21 through the lower cutting surface 222 (step S02).

As mentioned above, when the electronic component 2 is disposed in the accommodating part A, since the pin hole H communicates with the bottom surface of the accommodating part A and the depth is less than the length of the pin 21, a part of the pin 21 will be relative to the upper cutting surface. 110 outstanding. Preferably, the stitch cutting module 1 further includes at least one holding member 300, wherein the holding member 300 is, for example, a chuck and having a shape corresponding to the holding portion 22b. When the cutting operation is performed, the holding member 300 is slidably disposed in the opening O and The holding portion 22b of the electronic component 2 is held, whereby the electronic component 2 can be further fixed.

When the cutting member 220 is slidably disposed in the sliding groove G, the cutting member 220 essentially slides along a sliding direction orthogonal to the extending direction of the stitch 21, and as shown in FIG. 10, the upper cutting surface 110 is relatively The lower surface of the mold 100 is recessed, and the lower cutting surface 222 protrudes relative to the upper surface of the cutting part 220. Therefore, when the cutting part 220 slides below the upper mold 100, the protruding part of the lower cutting surface 222 will enter the upper cutting surface The recessed portion defined by 110 makes the upper mold 100 and the cutting part 220 substantially close together. In addition, the normal direction N of the upper cutting surface 110 and the lower cutting surface 222 is inclined with respect to the extension direction of the stitch 21. In this embodiment, the inclination angle is 10 to 45 degrees, preferably 20 degrees. Through this configuration, when the cutting member 220 slides and abuts against the stitch 21, the cutting member 220 will generate a shearing force on the stitch 21 to cut the lower end of the stitch 21 into a slope that is relatively inclined to the extension direction of the stitch 21, forming as The state shown in Figure 11. During the cutting process, the holder 300 and the pin hole H hold the base 22 and the pin 21 respectively, so the connection between the pin 21 and the base 22 will not be subjected to excessive torque to cause the pin 21 to break. In addition, the above-mentioned inclination angle can make the pins 21 have sharp ends, which not only improves the assembly efficiency and automation of the subsequent assembly operations of the electronic component 2, but also takes into account the mechanical strength of the pins 21 at the same time.

Furthermore, as shown in FIG. 10, the distance between these lower cutting surfaces 222 and the end surface 22a is equal. Therefore, when the electronic component 2 is assembled, the tips of all the pins 21 can be inserted into the holes of the assembly component at one time. However, according to actual assembly requirements, in other possible embodiments, the contact position of the lower cutting surface 222 with each pin 21 may also have a different distance from the end surface 22a, which is not limited by the present invention.

It is worth mentioning that in this embodiment, the upper cutting surface 110 is recessed relative to the lower surface of the upper mold 100, while the lower cutting surface 222 protrudes relative to the upper surface of the cutting member 220, and the cutting member 220 is relative to the fixing member 210. Sliding to realize the cutting of the stitch 21, but the invention of the present invention is not limited to this. In other embodiments, the upper cutting surface 110 may protrude relative to the lower surface of the upper mold 100, and the lower cutting surface 222 is relative to the cutting piece. The lower surface of 220 is recessed, or the cutting member 220 is fixed, and the upper mold 100 and the fixing member 210 slide relative to the cutting member 220, the same effect can also be achieved.

In addition, since the inclined portion 224b at the upper end of the vertical portion 224a is inclined with respect to the upper surface of the cutting member 220 and the vertical portion 224a, when the cutting member 220 abuts the pin 21, the contact portion with the pin 21 is substantially only inclined The boundary edge between the portion 224b and the upper surface of the cutting member 220 can make the cutting member 220 easier to cut the stitch 21. On the other hand, the inclined portion 224b at the lower end of the vertical portion 224a is inclined with respect to the lower surface of the cutting piece 220 and the vertical portion 224. Therefore, when the cutting piece 220 moves toward the inclined surface 214, the cut stitch 21 is not easy to stay on the cutting piece 220. The cutting member 220 can push a part of the cut pin 21 to the inclined surface 214 through the inclined portion 224b at the lower end, so that the pin 21 waste can be discharged smoothly, which is beneficial to the cutting operation.
