DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 5, A hot-melt coating device for a wire harness rubber hose sleeve, comprising a bottom frame 1, a base 2, a lifting assembly, a heating assembly for hot-melting the rubber hose, several groups of clamping assemblies arranged horizontally and evenly for clamping the rubber hose, a support assembly for supporting the wire harness, a moving assembly and a slider 8. Legs 3 are provided at the four corners below the bottom frame 1. First brackets 4 connected to the bottom frame 1 are provided on the left and right sides below the base 2. A moving assembly for the slider 8 to move is provided on the base 2. The clamping assembly includes a first motor, a bearing seat 6 and a fixed clamp 7. The first motor is provided at one end of the slider 8, and the bearing seat 6 is provided at the other end of the slider 8. The output end of the first motor penetrates through the slider 8 and is connected to the bearing seat 6. The fixed clamp 7 is provided on the bearing seat 6. In this embodiment, manual feeding is adopted. The fixed clamp 7 and the bearing seat 6 are connected in an assembled manner, and the fixed clamp 7 with different clamping ports can be replaced according to different materials, which is convenient for stably clamping the end of the wire harness. During the processing of materials, the moving assembly is used to control the forward and backward movement of the slider 8, and the first motor drives the bearing seat 6 to move synchronously, ensuring the all-round processing of materials of a certain length. How the first motor moves synchronously and how the first motor adjusts its speed according to requirements are well-known technical means to those skilled in the art and will not be elaborated in this article;

[0033] During the actual use process, it is found that a lifting assembly for controlling the lifting of the heating assembly is provided on two groups of legs 3 near one end of the bottom frame 1 below the bearing seat 6. The heating assembly includes a first mounting seat 9, a heating box 10 and an output head 11. The first mounting seat 9 is provided at the output end of the lifting assembly. The heating box 10 is provided on the first mounting seat 9. The output end of the heating box 10 is connected to the input end of the output head 11. Several groups of output holes 12 adapted to the corresponding clamping assemblies are provided at the output end of the output head 11. In this embodiment, the heating box 10 adopts a conventional automatic temperature control heating box 10 that can be purchased on the market. A temperature sensor and a temperature control switch are provided inside its box body. When the temperature sensor senses that the temperature reaches the high threshold, the temperature control switch controls the heating device to turn off. When the temperature sensor senses that the temperature is lower than the low threshold, the temperature control switch controls the heating device to turn off. The fan is used to discharge the air in the box into the output head 11, and the hot air finally discharges from the output holes 12. If the sizes of the output holes 12 are the same, the material located in the center is processed the fastest, while the materials located on both sides are processed the slowest, which results in inconsistent processing quality of the same batch of materials. To solve the above problems, after many experiments, the aperture of the output holes 12 arranged in sequence from the center of the output head 11 to both sides of the output head 11 becomes larger, ensuring uniform heat output of the output holes 12 above the output head 11.

[0034] During actual use, it is necessary to provide a certain support for the materials. In this embodiment, the support assembly includes a second bracket 13, a mounting tube 14, a first support plate 15, and a first support tube 16 with an upper opening. The second brackets 13 are provided at the four corners above the bottom frame 1. Through holes are provided on both the first bracket 4 and the second bracket 13. Two sets of the mounting tubes 14 are provided, and the corresponding mounting tubes 14 penetrate through the through holes on the corresponding first bracket 4 and the second bracket 13. The lower part of the first support plate 15 is respectively connected to the two sets of the mounting tubes 14. A number of sets of first support tubes 16 adapted to the corresponding clamping assemblies are provided on the first support plate 15. The end of the wire harness is clamped by the fixing clip 7, and the tail of the wire harness passes through the first support tube 16. The rubber tube is located between the fixing clip 7 and the first support tube 16.

[0035] In this embodiment, any one of the moving assemblies can be used to control the movement of the slider 8. For example, a cylinder can be used to control the movement of the slider 8, or a hydraulic cylinder can be used to control the movement of the slider 8. In this embodiment, a mechanical transmission with high stability is adopted. The moving assembly includes a guide rod 17, a second motor 18, a fixed seat 19, and a screw rod 20. The fixed seat 19 is provided at one end of the base 2 away from the support assembly. A screw hole and a guide hole are provided below the slider 8. The second motor 18 and two symmetrically arranged guide rods 17 are provided on the fixed seat 19. The second motor 18 is arranged between the two guide rods 17. The output end of the second motor 18 penetrates through the fixed seat 19 and is connected to the screw rod 20. The screw rod 20 is adapted to the screw hole, and the corresponding guide rod 17 is adapted to the corresponding guide hole. The second motor 18 drives the screw rod 20 to rotate. The base 2 is limited by the guide rod 17. The screw rod 20 penetrates through the screw hole below the base 2. As the second motor 18 rotates forward and backward, the slider 8 reciprocates back and forth on the base 2.

[0036] In this embodiment, any one of the lifting assemblies can be used to control the up and down movement of the heating assembly. In this embodiment, a lifting assembly with quick response is adopted. The lifting assembly includes a vertical plate 21, a first cylinder, and a second mounting seat 22.

The first cylinder on the vertical plate 21 drives the second mounting seat 22 to move up and down, further controlling the up and down movement of the heating assembly.

[0037] In the actual operation process, it is found that without a heat insulation device, first, it is unsafe for people to load and unload materials. Second, it is difficult to control the processing time. To solve the above problems, in this embodiment, a fast-responsive protection component is adopted. A protection component is arranged below the base 2. The protection component includes a second cylinder and a protection plate 23. Two groups of the second cylinders are arranged symmetrically left and right below the base 2. The output ends of the two groups of second cylinders are connected to the protection plate 23 for protecting the output hole 12. When the heat supply component is located below the base 2, the second cylinder drives the protection plate 23 to be located above the output hole 12 of the output head 11. When the heat supply component is located above the base 2, the second cylinder drives the protection plate 23 to be received below the base 2.

[0038] In the actual use process, it is found that the rubber hoses on the wire harness need to be positioned in the same way to meet the quality consistency of multiple groups of materials after being processed simultaneously. To meet the above requirements, an auxiliary positioning component is arranged on the slider 8. The auxiliary positioning component includes a hinged wall 24, a cross beam 25 and a positioning frame 26. The hinged walls 24 are symmetrically arranged on the left and right sides of the slider 8. One ends of the two groups of hinged walls 24 are hinged to the slider 8, and the other ends of the two groups of hinged walls 24 are connected to the cross beam 25. A number of positioning frames 26 for positioning the rubber hoses are arranged on the cross beam 25. When it is necessary to position the rubber hoses sleeved on the wire harness, during positioning, by rotating the hinge frame, the cross beam 25 with the positioning frame 26 approaches the wire harness. The positioning frame 26 is L-shaped. A wire harness groove is arranged on the lower wall of the positioning frame 26. One end of the rubber hose sleeve on the wire harness away from the base 2 abuts against the lower wall of the positioning frame 26, and the wire harness passes through the wire harness groove.

[0039] In the actual use process, it is necessary to ensure the stability of the wire harness. To meet the above requirements, in this embodiment, an auxiliary support component is arranged on the two groups of mounting pipes 14. The auxiliary support component includes a second support plate 27 and a number of groups of second support pipes 28 with upper openings. The left and right sides below the second support plate 27 are respectively connected to the corresponding mounting pipes 14. Second support pipes 28 adapted to the corresponding first support pipes 16 are arranged on the second support plate 27. The tail of the wire harness passes through the second support pipes 28 on the second support plate 27. Both the first support pipe 16 and the second support pipe 28 are provided with upper openings, which is convenient for loading and unloading.

[0042] Step 2: Clamp several groups of wire harnesses with rubber hoses on the corresponding fixing clips 7, and sequentially pass the tail ends of the wire harnesses through the corresponding first support tubes 16 and second support tubes 28;

[0043] Step 3: Start the heating device to preheat to the specified temperature. At this time, the second cylinder drives the protective plate 23 to be located above the output hole 12 to prevent hot air from overflowing, and wait for the heating device to heat to the specified stable temperature;

[0044] Step 4: The second cylinder drives the protective plate 23 to move towards the base 2 to expose the output head 11. The first cylinder drives the second mounting seat 22 to rise, and the second mounting seat 22 further drives the first mounting seat 9 to rise, so that the top of the output head 11 above the heating box 10 heats the rubber hoses on the corresponding wire harnesses;

[0045] Step 5: Start the first motor. The first motor drives the fixing clip 7 to rotate. Further, the fixing clip 7 drives the wire harness to rotate to ensure that the rubber hose fits the wire harness all around. During this process, the second motor 18 adjusts the position of the slider 8 to ensure that the rubber hose with a certain length completely fits the wire harness;

[0046] Step 6: After the rubber hose completely fits the wire harness, first the lifting assembly resets, and then the protection assembly resets.

[0047] Preferably, in Step 2, it is necessary to position the rubber hoses on the wire harnesses. When positioning, rotate the articulated frame so that the cross beam 25 with the positioning frame 26 approaches the wire harness. The positioning frame 26 is L-shaped, and a wire harness groove is provided on the lower wall of the positioning frame 26.
