Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically to an automotive wiring harness welding device. Background Technology
[0002] Automotive wiring harness welding equipment is a device that welds automotive wiring harnesses together. Its working principle is to convert high-frequency electrical energy into mechanical vibration energy, which is then applied to the metal wiring harness to generate frictional heat between the copper wires, thereby achieving seamless fusion. This device is widely used in the automotive parts manufacturing industry.
[0003] In the existing technology, after workers use welding equipment to weld wire harnesses, toxic or polluting gases may be generated, which will damage the working environment. Secondly, the temperature of the welded wire harness may be too high, which may burn workers when removing it, making it difficult for workers to remove the welded metal wire harness and resulting in low welding efficiency.
[0004] To overcome the above deficiencies, a prior art Chinese patent (application number 202121796132.1) discloses a welding device for automotive wiring harnesses, including a workbench with a back plate at the rear end of its top surface. A first hydraulic cylinder is provided on the upper part of the front side of the back plate. The piston rod of the first hydraulic cylinder faces downward and is fixedly connected to an ultrasonic transducer. A welding head is fixedly connected to the bottom end of the ultrasonic transducer. A pressure plate is provided on the workbench below the welding head. A semiconductor cooling chip is provided inside the pressure plate, and a blower is provided on the corresponding back plate. Support plates are provided on the workbench on both sides of the pressure plate. A bidirectional lead screw is rotatably connected between the two support plates. One end of the bidirectional lead screw passes through the corresponding support plate and is driven by a motor. Two sliders are symmetrically threaded on the two threaded sections of the bidirectional lead screw. A horizontal plate is fixedly connected to the top of the sliders. A second hydraulic cylinder is provided on both the front and rear sides of the horizontal plate. The piston rods of the two second hydraulic cylinders are arranged opposite each other and are fixedly connected to clamping plates.
[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, during the welding process, automotive wiring harness welding machines may produce sparks or impurities from broken welding wires. These sparks or impurities may be ejected onto the skin of workers when they are performing high-temperature welding, thereby endangering their health. Utility Model Content
[0006] The purpose of this utility model is to provide an automotive wiring harness welding device to solve the problems mentioned in the background art, such as the potential generation of toxic or polluting gases after welding, which damages the working environment; the possibility of burns to workers when removing the welded wiring harness due to excessively high temperature, which makes it difficult to remove the welded metal wiring harness and results in low welding efficiency; and the potential for sparks or impurities from broken welding wires during welding, which may be ejected onto the skin of workers during high-temperature welding, thus endangering their health.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an automotive wiring harness welding device, comprising a body, a workbench inside the body, an electric telescopic rod above the workbench, and a welding head fixedly installed at the bottom of the electric telescopic rod; a partition is provided at the lower end of the electric telescopic rod, and a cleaning mechanism is provided above the partition, the cleaning mechanism including an air pump, which is fixedly installed on both sides of the partition; an opening is provided inside the workbench, and a protective mechanism is provided below the opening, the protective mechanism including a striking rod, which is located at the bottom of the welding head.
[0008] Furthermore, a first groove is provided in the middle of the workbench, and a fixed shaft is provided inside the first groove, and a clamping plate is provided on the right side of the fixed shaft.
[0009] Furthermore, an anti-slip pad is provided on the inner side of the clamping plate, and a guide rod is provided on the right side of the clamping plate, with a return spring sleeved on the outer side of the guide rod.
[0010] Furthermore, the cleaning mechanism also includes a push-pull rod, the upper end of which is fixed to the middle of the electric telescopic rod, and the lower end of the air pump is provided with an air pipe that passes through the partition.
[0011] Furthermore, the protective mechanism also includes a protective plate, which is disposed inside the workbench, and a second groove is formed on each side of the protective plate.
[0012] Furthermore, a support plate is provided inside the workbench, and a rotating shaft is fixedly connected to the upper end of the support plate.
[0013] Furthermore, a seesaw is rotatably connected to the outside of the rotating shaft, and a magnet is provided on the upper surface of the seesaw, with the magnet on the surface of the seesaw corresponding to the magnet at the bottom of the striking rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. After the user finishes welding the metal wire harness using the automotive wire harness welding machine, he manipulates the electric telescopic rod to rise, causing the air pump to rise. This causes the push-pull rod to compress the gas in the air pump and introduce it into the air pipe, thereby cleaning the workbench with gas. This removes the odor and small impurities left after the metal wire harness welding is completed, thus achieving the effect of cleaning the working environment and preventing the small impurities left behind from adhering to the metal wire harness during the next welding, which would affect the processing accuracy of the metal wire harness.
[0016] Furthermore, the temperature of the welded part of the metal wire harness is high after welding, and it needs to be cooled down. By blowing air into the welded part of the workbench through an air pipe, the cooling process of the metal wire harness is reduced, thus improving the welding efficiency.
[0017] 2. When workers are welding metal wire harnesses, they must first operate the automatic telescopic rod to move down. The striking rod, which is fixedly connected to the bottom of the welding head, moves down along with the automatic telescopic rod. At this time, the striking rod strikes the seesaw, causing the other end of the seesaw to lift the protective plate, thereby preventing sparks or other impurities such as broken welding wires from being sprayed onto the workers' bodies and endangering their health. The installation of the protective plate improves the safety performance of the automotive wire harness welding machine. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: As Figure 1 and Figure 2 The technical solution shown is an automotive wiring harness welding device. To address the problems in existing technologies, such as the potential generation of toxic or polluting gases after welding, which damages the working environment, and the possibility of burns during removal due to excessively high wire harness temperatures, the device discloses an automotive wiring harness welding device. This device includes a body 1, a worktable 2 inside the body 1, an electrically operated telescopic rod 3 above the worktable 2, and a welding head 4 fixedly mounted at the bottom of the electric telescopic rod 3. A partition 5 is provided at the lower end of the telescopic rod 3, and a cleaning mechanism is provided above the partition 5. The cleaning mechanism includes an air pump 6, which is fixedly installed on both sides of the partition 5. A first groove 11 is provided in the middle of the workbench 2, and a fixed shaft 12 is provided inside the first groove 11. A clamping plate 13 is provided on the right side of the fixed shaft 12. An anti-slip pad 14 is provided on the inner side of the clamping plate 13, and a guide rod 15 is provided on the right side of the clamping plate 13. A return spring 16 is sleeved on the outer side of the guide rod 15. The cleaning mechanism also includes a push-pull rod 7, and the upper end of the push-pull rod 7 is fixed to the middle end of the electric telescopic rod 3. An air pipe 8 is provided at the lower end of the air pump 6, and the air pipe 8 passes through the partition 5.
[0028] Clamping plates 13 are provided on both sides of the first groove 11 in the middle of the workbench 2. The clamping plate 13 at the rear of the first groove 11 is fixedly connected to the workbench 2 via a fixed shaft 12. The clamping plate 13 at the front of the first groove 11 is connected to a guide rod 15. A return spring 16 is sleeved on the outside of the guide rod 15. One end of the return spring 16 is connected to the clamping plate 13, and the other end is connected to the workbench 2. When the user uses the automotive wire harness welding machine, he pushes the clamping plate 13 at the front of the first groove 11 forward to place the metal wire harness between the two clamping plates 13. The inner side of the clamping plate 13 is provided with an anti-slip pad 14, which increases the friction between the metal wire harness and the clamping plate 13, making the clamping plate 13 hold the metal wire harness more firmly. After securing the reinforcement, the operator manipulates the electric telescopic rod 3 to move it down, and the push-pull rod 7 is fixedly connected to the fixed sleeve of the electric telescopic rod 3. The air pump 6 is also fixedly connected to the partition 5, which is fixed at the telescopic point of the electric telescopic rod 3. When the electric telescopic rod 3 moves down, it drives the air pump 6 down, causing the push-pull rod 7 to draw gas from the outside through the air pipe 8, so that the push-pull rod 7 is located at the upper end inside the air pump 6. At this time, the welding head 4 is controlled to weld the metal wire harness. After the welding is completed, the electric telescopic rod 3 is moved up again, causing the air pump 6 to move up, so that the push-pull rod 7 compresses the gas inside the air pump 6 and blows the gas inside the air pump 6 through the air pipe 8 to the workbench 2 to clean the welding area on the workbench 2.
[0029] Example 2: Figures 3-7 The technical solution shown, based on Embodiment 1, addresses the issue that sparks or impurities from broken welding wires may occur during automotive wiring harness welding, potentially harming workers' health if these sparks or impurities come into contact with their skin during high-temperature welding. The solution discloses an automotive wiring harness welding device, comprising a body 1, a workbench 2 inside the body 1, an electric telescopic rod 3 above the workbench 2, and a welding head 4 fixedly mounted at the bottom of the electric telescopic rod 3. An opening 10 is provided inside the workbench 2, and a protective mechanism is provided below the opening 10, including a striking mechanism. The striking rod 9 is located at the bottom of the welding head 4. The inner side of the clamping plate 13 is provided with an anti-slip pad 14, and the right side of the clamping plate 13 is provided with a guide rod 15. A return spring 16 is sleeved on the outer side of the guide rod 15. The protective mechanism also includes a protective plate 17, which is located inside the workbench 2. The protective plate 17 has a second groove 18 on each side. The workbench 2 is provided with a support plate 19, and a rotating shaft 20 is fixedly connected to the upper end of the support plate 19. A rocker 21 is rotatably connected to the outer side of the rotating shaft 20. A magnet 22 is provided on the upper surface of the rocker 21, and the magnet 22 on the surface of the rocker 21 corresponds to the magnet 22 at the bottom of the striking rod 9.
[0030] When the user performs soldering on the wire harness, the electric telescopic rod 3 is moved downwards. A striking rod 9 is fixed to the bottom of the soldering head 4 below the electric telescopic rod 3. The striking rod 9 moves downwards along with the electric telescopic rod 3. When the striking rod 9 reaches the worktable 2, it descends through the opening 10 to the rocker plate 21 inside the worktable 2 and strikes the rocker plate 21. A magnet 22 is installed at the bottom of the striking rod 9, and a magnet 22 is also installed on the upper surface of the rocker plate 21, causing the striking rod 9 to attract the rocker plate 21. Furthermore, the seesaw 21 is rotatably connected to the rotating shaft 20 via the support plate 19. When one end of the seesaw 21 is struck by the striking rod 9, the other end pushes up the protective plate 17 provided on the surface of the seesaw 21, causing the protective plate 17 to move up to the surface of the workbench 2. This protects the human body during welding, preventing sparks or other impurities from being ejected onto the human body and endangering the health of the workers. In addition, the protective plate 17 has second grooves 18 on both sides, so that the protective plate 17 will not interfere with the metal wire harness clamping welding when it moves up.
