Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to a terminal core cutting mechanism. Background Technology

[0002] With the widespread adoption of communication cables that are a standard in the AI ​​industry, there is a huge demand for Slingshot 224G DP terminal cables in AI servers. As intelligent devices gradually replace manual labor, and production shifts from manual to automated processes, the industry's requirements for the precision of automated equipment and the quality of products are constantly increasing.

[0003] As is well known, terminal core cutting mechanisms are commonly used functional components in automated production processes, suitable for mass production. However, existing cutting mechanisms generally have a lower cutting blade fixed on the base of the terminal strip, and then an upper cutting blade presses down to complete the cutting. This structure is suitable for large-scale cutting of single-specification terminals, but because the terminals themselves are irregular in shape, often with multiple protrusions or irregular structures on the bottom, they cannot smoothly pass through the fixed lower blade along the guide path of the strip during the cutting process. Once it is necessary to switch to different specifications of terminal products, the machine must be stopped to replace the corresponding lower cutting blade and matching base. This results in low compatibility of existing cutting mechanisms, making them unable to adapt to different specifications of products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a terminal core cutting mechanism, comprising: A base plate, wherein a cutting blade is provided on the base plate, and a material discharge port is provided at the corresponding position of the cutting blade and the base plate; The terminal feed plate is movably connected to the base plate via multiple positioning posts, and the cutting blade is embedded in the terminal feed plate. The upper blade mounting base is connected to the terminal feed plate via multiple support columns, and a cutting upper blade is provided on the upper blade mounting base; A guide seat is mounted on a support column below the upper knife mounting seat, and multiple positioning pins are provided on the guide seat.

[0005] Furthermore, the terminal feed plate has a through groove along its length, and multiple moving slots for terminals to pass through are provided in the groove. Terminal cover plates are provided on both sides of the groove, and a moving channel for terminals to pass through is formed between the terminal cover plates and the groove.

[0006] Furthermore, both the chute and the cover plate have infeed ramps at their infeed ends.

[0007] Furthermore, the positioning pin includes a plurality of first positioning pins and a plurality of second positioning pins, and the cutting blade has a first positioning hole and a second positioning hole corresponding to the first positioning pins and the second positioning pins.

[0008] Furthermore, the guide seat and the upper blade mounting seat are fixedly connected by a connecting column, and a first buffer spring is also provided between the guide seat and the upper blade mounting seat.

[0009] Furthermore, a mounting block is provided on the upper blade mounting base, and an air passage connector is provided on the mounting block. Multiple through air passages are opened inside the upper cutting blade along its length direction, and the air passages are connected to the air passage connector through the mounting block.

[0010] Furthermore, a guide post is provided on the base plate, and a buffer plate is provided on the guide post. One end of the buffer plate is fixedly connected to the upper end face of the upper blade mounting base. An air passage is provided in the buffer plate to connect the mounting block and the cutting upper blade. A second buffer spring is sleeved on the guide post below the buffer plate.

[0011] Furthermore, a limiting post is also provided on the base plate, which can abut against the buffer plate.

[0012] The terminal core cutting mechanism provided in this application has the following advantages: The terminal feed channel is designed to move up and down with the upper cutting blade, making it easier to adapt to different product models and improving the compatibility of the cutting mechanism. By opening an air passage inside the upper cutting blade, and evacuating the internal air passage during the cutting process, the terminals are adsorbed onto the upper cutting blade, effectively preventing the terminals from tilting or splashing. By setting the first positioning pin and the second positioning pin, the terminal is further fixed, ensuring the smooth completion of the cutting process. Attached Figure Description

[0021] See Figures 1-5 This embodiment provides a terminal core cutting mechanism, including a base plate 10. A terminal feeding plate 12 is movably mounted on the base plate 10 via multiple positioning posts 11. An upper blade mounting seat 14 is mounted on the terminal feeding plate 12 via multiple support posts 13. An upper cutting blade 15 is mounted on the upper blade mounting seat 14. A lower cutting blade 16 is embedded in the middle of the terminal feeding plate 12 below the upper cutting blade 15. The lower cutting blade 16 is fixedly connected to the base plate 10. A material discharge port 161 is opened at the corresponding position of the lower cutting blade 16 and the base plate 10.

[0022] To facilitate the passage of the terminal strip to be cut, a through groove 121 is provided on the terminal feed plate 12 along its length. Multiple moving grooves 122 are also provided in the groove 121 for the downward protruding part of the terminal to pass through. Terminal cover plates 17 are provided on both sides of the groove 121, and a certain gap is left between the terminal cover plates 17 and the groove 121 to form a moving channel for the two ends of the terminal to pass through.

[0023] In order to fix the terminal during the cutting process, a first positioning hole 171 is opened at the corresponding position of the cutting blade 16 and the terminal cover plate 17. A second positioning hole 162 is also opened at the middle position of the cutting blade 16. The second positioning hole 162 is opened on both sides of the material discharge port 161.

[0024] In addition, a guide slope 163 is provided at the upper end of the material drop opening on the cutting blade to facilitate guiding the terminal when the cutting blade presses down. Similarly, the inlet end and outlet end of the chute 121 are provided with an inlet slope 123 and an outlet slope 124, respectively, for guiding the movement of the terminal strip.

[0025] Specifically, a guide seat 18 is provided on the support column 13 below the upper blade mounting seat 14, and the upper cutting blade 15 passes through the guide seat 18. A first buffer spring 19 is also provided between the guide seat 18 and the upper blade mounting seat, and the two are connected by a connecting column 20.

[0026] More specifically, a plurality of first positioning pins 21 and a plurality of second positioning pins 22 are respectively provided on the guide seat 18. The first positioning pins 21 can be inserted into the first positioning hole 171, and the second positioning pins 22 can be inserted into the second positioning hole 162.

[0027] To further buffer the cutting pressure of the upper blade pressing down, two guide posts 23 are also provided on the base plate 10. A buffer plate 24 is provided on the guide posts 23. One end of the buffer plate 24 is fixedly connected to the upper blade mounting seat 14. A second buffer spring 25 is sleeved on the guide post below the buffer plate. In addition, a limiting post 26 is also provided on the base plate, which can abut against the buffer plate.

[0028] In addition, to prevent the terminals from tilting or splashing out during the cutting process, one end of the buffer plate 24 is fixedly connected to the upper end face of the upper blade mounting base 14. The upper end face of the cutting upper blade 15 is flush with the upper end face of the upper blade mounting base. An interconnected air passage 151 is opened in the buffer plate 24 and the cutting upper blade. In this embodiment, since there are two sets of upward columnar protrusions on the terminal 29 to be cut, two sets of through air passages are opened in the cutting upper blade along its length direction. While positioning, the end face of the terminal is adsorbed onto the surface of the upper blade. A mounting block 27 is provided on the buffer plate, and an air passage connector 28 is provided on the mounting block 27. The air passage connector 28 is used to connect an external vacuum generator or other vacuuming structure.

[0029] Working principle: The terminal strip moves from the groove of the terminal feed plate and stops at the cutting position. The upper blade mounting base moves downward under the drive of external power, driving the upper cutting blade to the cutting position. At this time, the first positioning pin is inserted into the first positioning hole, and the second positioning pin can be inserted into the second positioning hole. The vacuum generator is started, and the terminal is attracted to the surface of the upper blade through the internal air passage, and then the cutting is completed. The vacuum generator is turned off, the terminal falls from the drop port, and the upper blade mounting base moves upward. In this embodiment, the upper end of the support column is set through the upper blade mounting base, so that the moving stroke of the upper blade mounting base is greater than the moving stroke of the guide seat and the terminal feed plate below. The upper blade mounting base drives the terminal feed plate to move upward, and then the terminal strip moves forward. At this time, the height of the terminal feed plate is higher than the height of the cutting blade. Therefore, the terminal strip is not affected by the cutting blade during the movement. Then it moves downward with the upper blade, and so on.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
