[0002] FFC cable, also known as Flexible Flat Cable (FFC), can arbitrarily select the number and spacing of wires, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency. It is most suitable for use as a data transmission cable between mobile parts and motherboards, between PCB boards, and in miniaturized electrical equipment. It requires a special processing method, and in the processing of flexible flat cables, the cutting step needs to ensure its accuracy. The existing cutting device for flexible flat cable processing needs to manually push the FFC flexible flat cable to move in order to complete the cutting, which leads to a high risk.

[0003] In particular, during the production process, flexible flat cables are arranged in multiple rows to form an integral plate-like structure. When using the flexible flat cables, the multiple flexible flat cables in the plate-like structure need to be cut and separated individually. The existing cutting and separation devices often make the number and spacing of separated wires inappropriate during cutting, resulting in inaccurate cutting. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.

[0032] Example 1

[0033] like Figure 1-4 As shown, a FFC flexible flat cable sliding cutting and separation device is characterized in that it includes: a base frame 1, the base frame 1 includes two cross bars 2 arranged at intervals, both ends of the two cross bars 2 and located between the two cross bars 2 are fixed with optical axes 3, a bottom plate 4 is arranged between the two optical axes 3, and both ends of the bottom plate 4 are respectively fixed on the two cross bars 2;

[0034] The sliding cutting mechanism 5 includes a fixed rod 6, a pressing handle 7 and a pressing block 9; support columns 8 are fixed at both ends of the fixed rod 6, and the two support columns 8 are respectively slidably connected to the optical axes 3 on both sides, and the two ends of the pressing block 9 are respectively slidably connected to the two support columns 8 up and down; an elastic component is fixed at the bottom of each pressing block 9; the pressing handle 7 is rotatably connected to the fixed rod 6, and acts on the pressing block 9 so that the pressing block 9 slides up and down between the two support columns 8; a cutting blade 10 is provided at the bottom of the pressing block 9.

[0035] It can be understood that the base frame 1 is formed by two cross bars 2 arranged in parallel at a certain distance, and circular holes are set at both ends of each cross bar 2. The two ends of the optical axis 3 are fixed on the circular holes on the same side, so that the base frame 1 with a frame structure is formed by the two cross bars 2 and the two optical axes 3, and there is a certain distance between the optical axis 3 and the ground so that the sliding cutting mechanism 5 can slide freely on the optical axis 3.

[0036] In the above scheme, the FFC flexible flat cable to be cut is placed on the bottom plate 4, and the pressing handle 7 is used to apply downward pressure to the pressing block 9, so that the pressing block 9 slides toward the bottom plate 4 between the two supporting columns 8 and approaches the bottom plate 4. When the blade 10 at the bottom of the pressing block 9 is pressed against the FFC flexible flat cable, a force is applied along the optical axis 3 by the handle, and the sliding cutting component slides on the optical axis 3 to complete the cutting of the FFC flexible flat cable by the blade 10. After the cutting is completed, under the action of the upward force of the elastic component, the pressing block 9 will reset upward along the supporting column 8, so that when not in operation, the blade 10 is away from the bottom plate 4.

[0037] As a preferred embodiment, a linear bearing 11 is provided at the bottom of each support column 8, and the two linear bearings 11 are respectively sleeved on the optical axes 3 on both sides. It can be understood that there are two support columns 8, and a linear bearing 11 is fixedly connected to the bottom of each support column 8. The linear bearing 11 can ensure that the support column 8 drives the lower pressing block 9 to slide freely on the optical axis 3, reduce the sliding resistance, and smoothly realize the cutting of the FFC flexible flat cable by the blade 10 on the lower pressing block 9.

[0038] As a preferred embodiment, the upper surface of the bottom plate 4 is provided with a groove 13 corresponding to the rod and the blade 10. It can be understood that a cutting area 12 corresponding to the blade 10 is specially provided on the bottom plate 4, and a plurality of grooves 13 are provided on the cutting area 12, so that when the blade 10 cuts the FFC flexible flat cable, there is a corresponding groove 13 corresponding to the position of the blade 10, which improves the cutting efficiency and has a good protective effect on the blade 10, preventing the blade 10 from touching the bottom plate 4 during cutting and causing wear of the blade 10.

[0039] As a preferred embodiment, two adjustable limit plates 14 are arranged at intervals on the upper side of the bottom plate 4, and a guide groove 15 is formed between the two limit plates 14. It can be understood that a square hole is arranged on the limit plate 14, and the limit plate 14 is adjusted by screws in conjunction with the square hole. In order to prevent the FFC flexible flat cable from sliding during cutting, the limit plates 14 on both sides form guide grooves 15 to fix the FFC flexible flat cable, which is helpful for accurate cutting of the FFC flexible flat cable.

[0040] As a preferred embodiment, a protrusion 16 is provided on the top of one end of each crossbar 2, a screw hole is provided on the protrusion 16, and a threaded rod 17 is provided on the screw hole. It can be understood that the position where the protrusion 16 is set is set on the same straight line as the support column 8. In order to be able to control the sliding cutting mechanism 5 to cut the FFC flexible flat cable within a certain range during the cutting process, the length of the threaded rod 17 is adjusted to achieve the purpose of adjusting the cutting range, that is, when the support columns 8 on both sides slide, the support columns 8 will hit the threaded rod 17 with a set length, so that the entire sliding cutting mechanism 5 slides left and right within a certain range.

[0041] As a preferred embodiment, the end of the pressing handle 7 is provided with a rotating ring 18, and the rotating ring 18 is sleeved on the fixed rod 6. The two sides of the rotating ring 18 are also provided with circular limit blocks 19 protruding from the fixed rod 6, and the rotating ring 18 is also provided with a pressing rod 20. It can be understood that the pressing handle 7 rotates on the fixed rod 6 through the rotating ring 18. During the rotation process, the pressing rod 20 on the side of the rotating ring 18 will press the pressing block 9 downward, and finally make the blade 10 abut against the FFC flexible flat cable, and the circular limit blocks 19 on both sides play a limiting role on the rotating ring 18, preventing the rotating ring 18 from sliding left and right, causing deviation in the pressing position of the pressing block 9, thereby causing the pressing block 9 to be unable to slide downward, and unable to achieve the cutting of the FFC flexible flat cable.

[0042] As a preferred embodiment, an extension plate 21 is further extended on one side of the lower pressing block 9, and the extension plate 21 is located on the same side of the pressing rod 20. It can be understood that the extension plate 21 is mainly used to provide sufficient pressing points for the pressing rod 20. When the pressing handle 7 is turned, the pressing rod 20 can act on the extension plate 21 to drive the lower pressing block 9 to slide downward.

[0043] As a preferred embodiment, each support column 8 is provided with a slide groove 22 on the side facing the bottom plate 4, and the two ends of the lower pressing block 9 are slidably connected to the slide groove 22. It can be understood that by fixing two plates on both sides of the support column 8, and both plates are protruding from the side of the support column 8, the protruding parts form the slide groove 22, and the two ends of the lower pressing block 9 are clamped in the slide groove 22, which is helpful for limiting the lower pressing block 9 and moving the lower pressing block 9 up and down.

[0044] As a preferred embodiment, the elastic component includes two return springs 23, and the two return springs 23 are respectively located on both sides of the bottom of the lower pressing block 9. It can be understood that one end of the return spring 23 is fixed to the bottom surface of the lower pressing block 9, and the other end is fixed to the outer wall of the linear bearing 11, which can ensure that the lower pressing block 9 is reset after cutting is completed.

[0045] As a preferred embodiment, a groove 24 corresponding to the guide groove 15 is provided on the crossbar 2. It can be understood that when the FFC flexible flat cable is placed in the guide groove 15, it needs to pass through the gap between the lower pressing block 9 and the bottom plate 4. The groove 24 facilitates the placement of the FFC flexible flat cable, so that the FFC flexible flat cable can pass through the gap smoothly.

[0046] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of explanation and illustration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention.
