Description

Electronic component and cutting device and device thereof

The invention relates to the technical field of electronic component processing, and in particular to an electronic component and a cutting device and device thereof.

Inserting the pins of electronic components into a printed circuit board (PCB) is currently done manually, but it is often labor intensive and the consistency of the components after insertion into the PCB is difficult to guarantee.

Industrial automation has gradually produced automated plug-in equipment that can replace the manual insertion of electronic components into the PCB, which greatly improves the consistency of the plug-in and saves labor costs. However, the automation of the industry is still not comparable to humans because the diameter of the insertion holes on the PCB is usually small, which is often not much larger than the diameter of the electronic component pins. Sometimes it happens during the process of automating the board. The electronic component pins cannot be smoothly inserted into the PCB due to insufficient wisdom recognition.

In order to overcome the above problems, various methods, such as those described in Japanese Patent No. JPH05198967A, are provided to help insert a pin into a specified position by providing a guide. But we see these methods are complicated and increase the cost of the equipment.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an electronic component is provided which enables improvement of the help pin to be smoothly inserted into a PCB by a simple and low-cost method. The present invention also provides a cutting apparatus and apparatus for processing the electronic component.

A first aspect of the invention provides an electronic component comprising an electronic component body and a lead thereof, the pin insertion end having a reduced diameter.

A second aspect of the present invention provides a cutting apparatus for cutting an electronic component as described above, the apparatus comprising at least one pin sharpening unit, the pin sharpening unit comprising: at least two first and second transmissions An arm, at least two oppositely disposed first and second cutting blades, at least one first driving mechanism;

The first and second cutting blades are disposed at opposite ends of the first and second transmission arms, and the first and second cutting blades are opposite or opposite by the movement of the first and second transmission arms. motion;

The first and second transmission arm phases drive the first and second transmission arms to move in opposite or opposite directions by the first driving mechanism.

The third party of the present invention also provides an apparatus that also includes a cutting device as described above.

As can be seen from the above, an embodiment of the present invention employs an electronic component including an electronic component body and its pins. The pin includes an insertion end for insertion into a PCB board, and the diameter of the pin insertion end is reduced. The embodiment of the invention also adopts a cutting device and a device for processing the above electronic component, and respectively obtain the following technical effects:

1. Since the diameter of the insertion end is reduced, this can increase the difference in the diameter between the pin and the pin hole on the PCB board, so it can better help to accurately insert the pin into the pin hole of the PCB board.

2. Since the cutting device includes a pin sharpening unit, the pin can be cut into a structure having a reduced diameter at the end of the pin as described above.

3. Since the pins of the electronic component are placed in the middle of the first and second cutting blades, the driving mechanism drives the first and second transmitting arms to drive the first and second cutting blades thereon to face each other. Movement until the pins are cut off, then the first and second cutting blades move in opposite directions to each other, and then the electronic components that have been cut are removed, and the new electronic components that need to be cut are placed, so that they can be automatically or Semi-automatically complete the cutting of the electronic component pins.

4, because the first cutting blade and the second cutting blade are misaligned, such that the first cutting knife cuts the pin and passes over the first receiving position, and does not directly Abuts against the receiving position, causing wear of the first cutting surface. As described in the above principle, the third cutting blade and the fourth cutting blade are misaligned.

5. When the first cutting blade and the second cutting blade are misaligned, the device further includes a compression bar disposed on one of the cutting blades and opposite to the other cutting blade, and thus, when the first cutting blade After the first cutting surface completes the cutting of the lead, it continues to abut against the pressing strip above the first receiving position, so that the remaining portion of the electronic component pin insertion end that is not sheared is also extruded into a bevel, thereby further The diameter of the insertion end of the electronic component is reduced.

6. Since the electronic components are usually connected together by a paper strip, in order to complete the automated process, in some cases, the electronic components are first placed in at least one of the cutting units, and the pins are The tape is cut and then placed in the pin sharpening unit to cut the foot.
