In the above-mentioned industries, it is often necessary to use precision electronic components such as diodes and transistors. These electronic components have slender pins, and the pins need to be pre-set through flexible circuit boards or hard circuit boards during assembly. holes, solder the pins and the circuit board to join each other. However, based on product design specifications and the overall volume of the product, the gap between the hole and the pin is quite small, requiring manual assembly, which is not only time-consuming and expensive, but also when the number of pins of a single electronic component increases , the difficulty of assembly work will be further improved.

To this end, one of the solutions is to cut the pins of electronic components to form a beveled shape with a tip, so that only the tip of the pin needs to be inserted into the hole during assembly to ensure that all the pins are uniform.

As shown in FIG. 6 , the fixing member 210 is formed with a chute G and an inclined surface 214 , wherein the chute G is recessed relative to the upper surface of the fixing member 210 and has a bottom surface 212 , and the inclined surface 214 is connected to the bottom surface 212 and is opposite to the bottom surface 212 Inclined to discharge the waste after the pin 21 is cut. Preferably, a plurality of locking holes F are also formed on the upper surface of the fixing member 210 for providing the aforementioned locking member for locking.

On the other hand, the cutting member 220 is slidably arranged in the sliding groove G and forms at least one 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. The number thereof is, for example, four , to cut the pin 21. Preferably, the cutting element 220 also 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 , respectively arranged at the upper end and the lower end of the vertical portion 224a and inclined relative to the vertical portion 224a, thereby facilitating the cutting operation and assisting the cutting member 220 to discharge the cut stitches 21 waste. The details of this part will be later detailed in the text.

How to cut the pins 21 of the electronic component 2 will be described in detail below. Please refer to FIGS. 8 to 11, wherein FIG. The front view schematic diagram when the group cuts the pins of the electronic components. Fig. 10 is a partially enlarged schematic diagram of the area X in Fig. 9, and Fig. 11 is a perspective view of the electronic components in Fig. The upper mold 100 is presented in a transparent form. The cutting method of this embodiment includes: disposing the electronic component 2 in the accommodating part A and making the pin 21 pass through the pinhole H and protrude relative to the upper cutting surface 110 (step S01), and the cutting part 220 is relative to the fixing part 210 Slide and cut the pin 21 through the lower cutting surface 222 (step S02 ).

As mentioned above, when the electronic component 2 is arranged in the accommodating part A, because the pinhole H communicates with the bottom surface of the accommodating part A and the depth is smaller than the length of the stitches 21, a part of the stitches 21 will be opposite to the upper cutting surface. 110 outstanding. Preferably, the stitch cutting module 1 further includes at least one holder 300, wherein the holder 300 is, for example, a collet and its shape corresponds to the holding portion 22b. When the cutting operation is performed, the holder 300 is slid in the opening O and The holding portion 22 b holding the electronic component 2 can further fix the electronic component 2 .

When the cutting piece 220 is slid in the sliding groove G, the cutting piece 220 slides substantially along a sliding direction perpendicular to the extending direction of the stitches 21, and as shown in FIG. 10 , the upper cutting surface 110 is opposite to the upper The lower surface of the mold 100 is concave, and the lower cutting surface 222 protrudes relative to the upper surface of the cutting piece 220, so when the cutting piece 220 slides to the bottom of the upper mold 100, the protruding part of the lower cutting surface 222 will enter the upper cutting surface. The concave part defined by 110 makes the upper mold 100 and the cutting part 220 substantially completely close together. In addition, the normal direction N of the upper cutting surface 110 and the lower cutting surface 222 is inclined relative to the extending direction of the stitches 21 , and the inclination angle in this embodiment is 10-45 degrees, preferably 20 degrees. With such a configuration, when the cutting piece 220 slides and abuts against the pin 21, the cutting piece 220 will generate a shear force on the pin 21 so as to cut the lower end of the pin 21 into a slope that is relatively inclined to the extending direction of the pin 21, forming a slope as shown in FIG. The state shown in Figure 11. Since the holder 300 and the pinhole H respectively hold the base 22 and the pin 21 during the cutting process, 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 produce sharp points, which not only improves the assembly efficiency and automation of the subsequent assembly operation of the electronic component 2 , but also can take into account the mechanical strength of the pins 21 at the same time.

Furthermore, as shown in FIG. 10, the distances between these undercut surfaces 222 and the end surface 22a are equal. Therefore, when the electronic component 2 is assembled, the tips of all the pins 21 can be inserted into the holes of the assembled component at one time. However, according to actual assembly requirements, in other possible embodiments, the positions where the lower cutting surface 222 contacts each pin 21 may also have different distances 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 piece 220, and the cutting piece 220 is relatively opposite to the fixing piece 210. Slide to realize the cutting of pin 21, but the present invention is not limited thereto. In other embodiments, it is also possible that the upper cutting surface 110 protrudes relative to the lower surface of the upper die 100, while the lower cutting surface 222 protrudes relative to the cutting piece 220 The lower surface of the upper mold 100 and the fixing member 210 slide relative to the cutting member 220, or the cutting member 220 is fixed, and 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 relative to the upper surface of the cutting piece 220 and the vertical portion 224a, when the cutting piece 220 abuts against the pin 21, the contact portion with the pin 21 is substantially only inclined. The border between the portion 224b and the upper surface of the cutting piece 220 can make it easier for the cutting piece 220 to cut off the stitches 21 . On the other hand, the inclined portion 224b at the lower end of the vertical portion 224a is inclined relative to the lower surface of the cutting piece 220 and the vertical portion 224, so when the cutting piece 220 moves toward the inclined surface 214, the cut stitches 21 are not easy to stay on the cutting piece 220. and the cutting member 220 can push a part of the cut pin 21 against the inclined surface 214 through the inclined portion 224b at the lower end, so that the waste material of the pin 21 can be discharged smoothly, which is beneficial to the cutting operation.

The present invention has been disclosed above with preferred embodiments, but those skilled in the art should understand that the above embodiments are only for describing the present invention and should not be interpreted as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the above-mentioned embodiments should be included in the scope of the present invention.
