Abstract
Description
Technical Field
[0001] The invention relates to the field of electronic component pin processing, and more specifically, to an automatic pin bending and cutting integrated fixture. Background Art
[0002] During the production and processing of electronic components, it is often necessary to cut and bend their pins. After the bending process, the first is to reduce the damage and thermal stress caused by direct bending at right angles, and the second is to increase the thermal capacity. Especially in the field of communications, fiber-optic communication is widely used because of its many advantages such as extremely wide bandwidth, low signal attenuation, low environmental impact, rich material sources, and good scalability. Fiber-optic transceivers, as a conversion unit for exchanging electrical signals with optical signals (also known as photoelectric converters), are an important means to achieve fiber-optic communication. At present, they have become the main product in the field of fiber-optic communication and have broad market prospects. There are two important components in the structure of fiber-optic transceivers: optical transmitter components and optical receiver components. Optical transmitter components are a converter that converts electrical signals into optical signals; and optical receiver components are a converter that converts optical signals into electrical signals. Both converters are core components of fiber-optic transceivers. Among them, the optical transmitter component generally has four or three pins (PIN pins), and the optical receiver component generally has five or four pins (PIN pins). And these pins must be soldered on a PCB printed circuit board to realize their functions. Due to the limitation of the spatial layout of the optical transceiver, the optical transmitting component and the optical receiving component need to be bent and trimmed before welding, and the bending angle and trimming length of the pins vary with the specifications and models of the products. In the existing production process, many of them are still completed by two processes, trimming and bending, which is inefficient and has high manufacturing costs. There are also integrated devices for trimming and bending pins, but they are usually expensive, complex, and cannot be adjusted in height to be compatible with pins of different lengths, which brings great inconvenience to the production and processing of electronic components.

The thickness of the end of the clamping plate 112 is less than the thickness of one end close to the clamping block 111. The clamping plate 112 abuts against the electronic component 6 to stabilize the electronic component 6, so as to facilitate the cutting assembly 31 to cut the tube pin 62; the abutting surface 1121 abuts against the pin, and when the bending assembly 21 bends the pin 62, the pin 62 is bent along the inclined surface 1122, so that the damage to the electronic component 6 that may be caused by the bending of the pin 62 can be avoided, thereby improving the working guarantee of the clamp.

The bending portion 214 is arranged corresponding to the clamping plate 112, and at least part of the clamping plate 112 is located directly above the bending portion 214. In this way, it can be ensured that when the clamping plate 112 is pressed against the electronic component 6, the bending assembly 21 can bend the pin 62. Further optionally: the bending hole 213 includes a first bending hole 2131, a second bending hole 2132 and a third bending hole 2133, the first bending hole 2131 is a circular hole, the second bending hole 2132 and the third bending hole 2133 are runway-shaped, and the length of the third bending hole 2133 is greater than the length of the second bending hole 2132.

The final formed molded product is as follows. Fig.12 Optionally, the bending parts 214 are arranged in a plurality at intervals, and the fixing block 311 is provided with a plurality of fixing openings, which are all arranged corresponding to the cutting blade 3123 and the blanking opening 3124.
