Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically to a flat cable hot pressing forming device. Background Technology

[0002] Flat cables (ribbon cables) are flat cables composed of multiple conductors arranged in parallel. They possess characteristics such as heat radiation resistance, cold resistance, and acid and alkali resistance. The operating voltage range is 450 / 750V to 0.6 / 1kV, and the applicable ambient temperature is -40~+70℃. The conductive cores feature a flexible structure design, and the insulation layer uses nitrile composite or silicone rubber materials. The sheath can be made of polyurethane, PVC, or silicone rubber. Some models can be equipped with load-bearing components such as galvanized steel wire rope.

[0003] In the processing of flat cables, thermoforming is a crucial step. However, current thermoforming equipment generally performs thermoforming directly on flat cables. For some cables with thick adhesive layers and large dimensions, the surface softens rapidly while the interior remains in a low-temperature rigid state, which is prone to micro-cracks due to thermal stress, affecting the quality of the cable. Therefore, improvements are urgently needed. Utility Model Content

[0027] Please see Figure 1-5 One embodiment of this utility model provides: a flat cable hot pressing forming device, including a device platform 1, and further including...

[0028] The preheating box 2 is fixed on the surface of the device platform 1. The upper end of the preheating box 2 is equipped with a guide wheel 5, and the lower end of the preheating box 2 is equipped with an inlet wheel 4 and an outlet wheel 8 respectively.

[0029] The hot pressing structure 1001 is disposed on the surface of the device platform 1 on one side of the preheating box 2. The hot pressing structure 1001 includes an upper hot pressing mold 10 and a lower hot pressing mold 11. The lower hot pressing mold 11 is fixed on the surface of the device platform 1 on one side of the preheating box 2 and is disposed above the upper hot pressing mold 10. A hydraulic cylinder 9 is installed on the outer wall of the preheating box 2 above the upper hot pressing mold 10, and the output end of the hydraulic cylinder 9 is fixedly connected to the upper hot pressing mold 10. A flat cable body 6 is inserted inside the hot pressing structure 1001.

[0030] Specifically, after preheating, the flat cable body 6 passes through the hot pressing structure 1001. The hydraulic cylinder 9 drives the upper hot pressing mold 10 to press down, and the upper hot pressing mold 10 and the lower hot pressing mold 11 cooperate to complete the hot pressing forming process.

[0031] The preheating structure 7 is set inside the preheating box 2. The preheating structure 7 includes a first hot air pipe 12, a central hot air pipe 13, and a second hot air pipe 14. The central hot air pipe 13 is fixed inside the preheating box 2, and the first hot air pipe 12 and the second hot air pipe 14 are respectively fixed on both sides of the central hot air pipe 13.

[0032] Heating box 16 is installed on one side of the surface of device platform 1. Heating rod 17 is installed inside heating box 16. Air supply pipe 18 is installed on one side of the top of heating box 16. Air supply fan 15 is installed on the surface of device platform 1 on one side of heating box 16, and the output end of air supply fan 15 is connected to heating box 16.

[0033] Specifically, the inlet wheel 4, the guide wheel 5, and the outlet wheel 8 inside the preheating box 2 support and guide the flat cable body 6. Since the preheating box 2 is equipped with a preheating structure 7, when the flat cable body 6 passes between the first hot air pipe 12, the central hot air pipe 13, and the second hot air pipe 14, the blower 15 sends air into the heating box 16. After being filtered by the dust filter 1601 and heated by the heating rod 17, the air is introduced into the first hot air pipe 12, the central hot air pipe 13, and the second hot air pipe 14 through the air supply pipe 18, and blown out from the first air outlet 1201, the central air outlet 1301, and the second air outlet 1401 respectively, uniformly heating the flat cable body 6. The adhesive layer and the insulation layer of the heated flat cable body 6 reach a semi-softened state in advance, so that the insulation layer and the adhesive layer are "gradiently heated", reducing the temperature difference and preventing damage to the substrate, thereby preventing thermal stress cracks in the flat cable.

[0034] One end of the flat cable body 6 passes through the preheating box 2 and passes through the outlet wheel 8, the guide wheel 5 and the inlet wheel 4 in sequence. The flat cable body 6 passes between the first hot air pipe 12, the central hot air pipe 13 and the second hot air pipe 14.

[0035] The first hot air pipe 12 and the second hot air pipe 14 are respectively provided with a first air outlet 1201 and a second air outlet 1401 on the outer wall of the side close to the flat cable body 6, and the central air outlet 1301 is provided on the outer walls of both sides of the central hot air pipe 13.

[0038] A dust removal structure 3 is provided on the outer wall of the preheating box 2 on one side of the inlet wheel 4. The dust removal structure 3 includes a dust removal duct 19, a dust removal brush 20 and an exhaust duct 22.

[0039] The dust removal duct 19 is installed on the outer wall of the preheating box 2 on one side of the inlet wheel 4, and the dust removal duct 19 has a C-shaped hollow structure. The exhaust duct 22 is installed on the outer wall of one side of the dust removal duct 19.

[0040] Dust removal brush 20 is installed on the inner wall of the top and bottom of dust removal duct 19, and a dust suction port 21 is provided on the inner wall of dust removal duct 19 on one side of dust removal brush 20;

[0041] Furthermore, before the flat cable body 6 enters the preheating chamber 2, the flat cable body 6 passes through the dust removal structure 3 and passes through the dust removal duct 19. The dust removal brush 20 brushes off the dust and impurities on the surface of the flat cable body 6. The exhaust duct 22 is connected to an external vacuum cleaner. The dust removal duct 19 sucks away the dust and impurities through the suction port 21, which facilitates the dust removal of the flat cable and ensures the quality of hot pressing.

[0042] In this embodiment, the flat cable body 6 first passes through the interior of the preheating chamber 2, then through the hot pressing structure 1001. The inlet wheel 4, guide wheel 5, and outlet wheel 8 inside the preheating chamber 2 support and guide the flat cable body 6. Since the preheating chamber 2 is equipped with a preheating structure 7, when the flat cable body 6 passes between the first hot air pipe 12, the central hot air pipe 13, and the second hot air pipe 14, the blower 15 sends air into the heating chamber 16. After being filtered by the dust filter 1601 and heated by the heating rod 17, the air is introduced through the air supply pipe 18 into the first hot air pipe 12, the central hot air pipe 13, and the second hot air pipe 14, and then blown out from the first air outlet 1201, the central air outlet 1301, and the second air outlet 1401 respectively, uniformly heating the flat cable body 6. The adhesive layer and insulation layer of the flat cable body 6 are pre-softened to a semi-softened state, allowing the insulation layer and adhesive layer to be "gradiently heated," reducing the temperature difference and preventing damage to the substrate, thereby preventing thermal stress cracks in the flat cable. Then, after preheating, the flat cable body 6 passes through the hot pressing structure 1001. The hydraulic cylinder 9 drives the upper hot pressing mold 10 to press down. The upper hot pressing mold 10 and the lower hot pressing mold 11 cooperate to complete the hot pressing process. In addition, before the flat cable body 6 enters the preheating chamber 2, it passes through the dust removal structure 3 and passes through the dust removal duct 19. The dust removal brush 20 brushes off the dust and impurities on the surface of the flat cable body 6. The exhaust duct 22 is connected to an external vacuum cleaner, and the dust removal duct 19 sucks away the dust and impurities through the suction port 21, thus facilitating dust removal of the flat cable and ensuring the quality of hot pressing.

[0043] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
