Problems solved by technology

[0003] After the FFC flat cable is manufactured, it is necessary to perform a tensile test on the FFC cable to determine whether its breaking force meets the requirements for use. Therefore, it is usually necessary for the workers to manually strip the metal wires, and then manually clamp the FFC cable to the fixture, and make the jaws clamp the metal wires, and then perform a tensile test. The process of stripping the metal wires is time-consuming Laborious, resulting in low efficiency of the entire pull test

Embodiment 1

[0027] The embodiment is basically as attached figure 1 Shown: FFC flat cable tensile testing machine, including the operation box 1, the top of the operation box 1 is fixedly connected with two guide rods 4 arranged symmetrically, the guide rod 4 is provided with a horizontal plate 8 and a support plate 5, the horizontal plate 8 is located on Above the support plate 5, there is a fixture 6 on the support plate 5. The fixture 6 in this embodiment is fixedly connected to the support plate 5 through bolts. The fixture 6 is used to clamp and fix the FFC flat cable. There is a fixture on the full-automatic insertion force testing machine in the art.

[0028] In this embodiment, the horizontal plate 8 is fixedly connected with the guide rod 4, the support plate 5 is vertically slidably matched with the guide rod 4, the two guide rods 4 pass through the support plate 5, and the operation box 1 is provided with a drive support plate 5 vertically Sliding drive unit, the drive unit in...

Embodiment 2

[0038] Such as image 3As shown, the difference between the FFC flat cable tensile testing machine and the first embodiment is that a groove 20 is provided on the end surface of one of the two clamping parts 14, and a convex groove is provided on the other clamping part 14. The protrusion can be inserted into the groove 20.

[0039] In this solution, when the two jaws 11 are closed together, the groove 20 of one of the clamping parts 14 can be made to cooperate with the protrusion of the other clamping part 14, even if the protrusion of one of the clamping parts 14 The part is inserted into the groove 20 of another clamping part 14, so that the metal wire can be clamped tighter, the clamping force generated on the metal wire is better, and it is more stable in the process of the tensile test, and the metal wire is not easy to be separated from the two sides. The jaws 11 fall off.

Embodiment 3

[0041] Such as Figure 4 As shown, the difference between the FFC flat cable tensile testing machine and the first embodiment is that the jig 6 is provided with a horizontally arranged slot 19, the right end of the slot 19 communicates with the right end of the jig 6, and the top of the slot 19 is At the open end, the front and rear sides of the slot 19 are provided with a splint 18 and a power piece that drives the splint 18 to slide in a direction perpendicular to the slot 19 .

[0042] The power parts in this embodiment are all clamping cylinders 15, and both sides of the slot 19 are provided with sliding chambers 16. One side is provided with a mounting cavity 17, two clamping cylinders 15 are respectively located in the mounting cavity 17, the sliding cavity 16 is connected with the slot 19 and the mounting cavity 17, and the output shaft of the clamping cylinder 15 passes through the two splints 18 respectively. Screw secure connection.

[0043] This embodiment provide...

Abstract

The invention relates to the technical field of tension testing equipment, and discloses an FFC flat cable tension testing machine which comprises an operation box, two guide rods which are symmetrically arranged are fixedly connected to the operation box, a transverse plate and a supporting plate are arranged on the guide rods, the transverse plate is located above the supporting plate, a jig is arranged on the supporting plate, the transverse plate is fixedly connected with the guide rod, the supporting plate is in vertical sliding fit with the guide rod, a driving unit for driving the supporting plate to vertically slide is arranged in the operation box, the transverse plate is connected with a tension sensor, the tension sensor is connected with a pneumatic clamp, the pneumatic clamp is provided with two clamping jaws which are symmetrically arranged, the sides, away from each other, of the two clamping jaws are each provided with a cutter, and the sides, close to each other, of the two clamping jaws are each provided with a clamping part. According to the invention, the efficiency of detecting the tensile force of the FFC can be improved, the operation of manually stripping a metal wire can be avoided, and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of tensile testing equipment, in particular to an FFC flat cable tensile testing machine. Background technique [0002] FFC flat cable, also known as FFC flat cable, is a new type of data cable made of PET insulating material and extremely thin tinned flat copper wire through a high-tech automatic equipment production line. It is widely used in various printers The connection between the print head and the motherboard, the signal transmission and circuit board connection of plotters, scanners, copiers, audio, LCD appliances, fax machines, various DVD players and other products. [0003] After the FFC flat cable is manufactured, it is necessary to perform a tensile test on the FFC cable to determine whether its breaking force meets the requirements for use. Therefore, it is usually necessary for the workers to manually strip the metal wires, and then manually clamp the FFC cable to the jig, and make the jaws...
