Description

Technical Field

[0001] This invention belongs to the field of wire harness welding technology, specifically referring to a wire harness welding device with fixed components. Background Technology

[0002] As a key component for transmitting electrical energy and signals in electrical equipment, wire harnesses require a firm and reliable connection between each wire and terminal during the manufacturing process. Ultrasonic welding technology is often used, which uses high-frequency mechanical vibration to create a metallurgical bond at the molecular level in metal wires, achieving solid-state welding without molten material or pollution.

[0003] Current wire harness welding equipment with fixed components has the following problems:

[0004] Existing wire harness welding equipment with fixed components lacks the ability to adjust the tensile strength according to the wire harness diameter. This results in thin wire harnesses breaking under strong and fast tensile tests, while thick wire harnesses cannot be accurately tested for welding quality under weak and slow tensile tests. Furthermore, it lacks the ability to automatically change the welding terminals. Therefore, it cannot meet the current usage requirements for wire harness welding equipment with fixed components. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this solution provides a wire harness welding device with a fixed component that can adjust the tensile strength according to the diameter of the wire harness and automatically change the welding terminals.

[0006] The technical solution adopted in this solution is as follows: This solution proposes a wire harness welding device with a fixed component, including a conductor platform, an arc-shaped groove, a welding platform, a welding groove, a plug-in type fixed end mechanism, and a thermomagnetic type positioning mechanism. The arc-shaped groove is located on the upper wall of the conductor platform and is open on three sides. The welding platform is located on one side of the conductor platform, and the welding groove is located on the upper wall of the welding platform at the end away from the conductor platform. The plug-in type fixed end mechanism includes a driving component, a guide component, and a clamping component. The driving component is located on the side of the welding platform away from the conductor platform, the guide component is located at the end of the welding platform close to the driving component, and the clamping component is located at the end of the guide component away from the driving component. The thermomagnetic type positioning mechanism includes a sliding drive component, a wire clamping component, and a demagnetizing component. The sliding drive component is located between the conductor platform and the welding platform, the wire clamping component is located on the sliding drive component, and the demagnetizing component is located on the side wall of the wire clamping component.

[0007] As a further preferred embodiment of the present invention, the driving assembly includes a driving motor and a driving frame. The driving motor is located on the side of the welding station away from the wire guide, and the driving frame is located on the power end of the driving motor. The guide assembly includes a guide ring, a guide groove, a sliding plate, and a guide spring. The guide ring is rotatably located on the outer side of the welding station near the driving motor. Multiple guide grooves are located on the side of the guide ring away from the welding station. The guide grooves are open on both sides. The sliding plate is slidably located inside the guide groove. The guide spring is located between the sliding plate and the inner wall of the guide groove, and the guide spring is in an extended state. The clamping assembly includes a clamping box and a heat-resistant rubber layer. The clamping box is located on the side of the sliding plate away from the guide groove and is open at one end. The heat-resistant rubber layer is symmetrically located on the upper and lower walls of the clamping box, and the initial spacing between the heat-resistant rubber layers is less than the thickness of the terminal.

[0008] In use, the initial state is that the guide spring is in the extended state. The terminals are inserted between the heat-resistant rubber layers inside the clamping box. The terminals are clamped inside the clamping box by the deformation of the heat-resistant rubber layers. The drive motor drives the drive frame to rotate through the power end. The drive frame drives the guide ring to rotate. The guide ring drives the sliding plate to rotate synchronously through the guide groove. The sliding plate drives each group of terminals to enter the table above the welding station through the clamping box, waiting for the ultrasonic welding equipment to perform the downward welding operation.

[0009] Preferably, the sliding drive assembly includes a guide post, a sliding block, a sliding drive spring, a sliding magnet, and a sliding drive electromagnet. The guide post is symmetrically arranged between the lead frame and the welding station, and is rotatably positioned between the lead frame and the welding station. The sliding block is slidably disposed outside the guide post. The sliding drive spring is disposed between the lead frame and the sliding block outside the guide post. The sliding magnet is disposed on the side of the sliding block away from the sliding drive spring. The sliding drive electromagnet is disposed on the side wall of the welding station outside the guide post, with the sliding magnet and the sliding drive electromagnet positioned opposite each other. The wire clamping assembly includes an arc-shaped rod, a wire clamping block, a half-sleeve rubber sleeve, and a connecting electromagnet. The arc-shaped rod is disposed on the upper wall of the sliding block, and the wire clamping block is disposed at the end of the arc-shaped rod away from the sliding block. The half-sleeve rubber sleeve... Located on the side of the clamping block away from the arc-shaped rod, two sets of half-sleeve rubber cylinders are arranged opposite each other. The connecting electromagnet is located on the side of the arc-shaped rod close to the clamping block, and the two sets of connecting electromagnets are arranged opposite each other. The demagnetizing component includes a temperature-conducting copper rod, a strip groove, a temperature-resistant strip magnet, a soft iron block, and a temperature-resistant magnetic column. Multiple sets of the temperature-conducting copper rods are installed through the inner wall of the welding table, and the temperature-conducting copper rods are flush with the surface of the welding table. The strip groove is located on the upper wall of the welding table near the wire guide, and is open at the top. The temperature-resistant strip magnet is located inside the strip groove. The soft iron block is located on the side of the clamping block close to the temperature-conducting copper rod, and is arranged opposite to the temperature-conducting copper rod. The temperature-resistant magnetic column is located on the side of the soft iron block close to the temperature-conducting copper rod, and a magnetic shielding layer is provided on the outside of the temperature-resistant magnetic column.

[0010] In use, the electromagnets are energized to generate magnetism. The two sets of electromagnets, with their like poles facing each other, repel each other through the repulsive magnetic field they generate, causing them to move in opposite directions. The electromagnets push the sliding block via an arc-shaped rod. The sliding block, under the elastic deformation of the sliding drive spring, slides along the guide post, causing the guide post to rotate synchronously. The circular cavity formed by the two sets of half-rubber sleeves opens, and the wire harness is placed between the half-rubber sleeves, with the end of the wire harness furthest from the half-rubber sleeve placed on the bottom wall of the arc-shaped groove. Then, the electromagnets are de-energized and demagnetized. The sliding drive spring elastically resets, causing the sliding block to rotate via the guide post. The sliding block then moves back along the arc-shaped groove. The rod drives the clamping block to move relative to each other. The clamping block drives the half-set rubber cylinder to clamp the wire harness. The sliding electromagnet is energized and generates magnetism. The sliding electromagnet and the sliding magnetic block are set with opposite poles. The sliding electromagnet is fixed to the side wall of the welding table and attracts the sliding magnetic block by magnetic force. The sliding magnetic block drives the sliding block to overcome the elastic force of the sliding spring and slide along the guide post. The sliding block drives the clamping block to move closer to the welding table through the arc rod. The clamping block drives the wire harness to move to the welding table surface of the welding table through the half-set rubber cylinder. At this time, the metal wire of the wire harness is located on the upper wall of the terminal.

[0011] Move the ultrasonic welding equipment to one side of the welding table. The ultrasonic welding equipment presses the metal wire and terminal down onto the welding table surface together. Under the pressure of the ultrasonic welding equipment, the wire harness is pulled out a distance between the half rubber tubes to avoid the wire harness being pulled excessively. The ultrasonic welding equipment generates heat through high-frequency vibration and friction, causing the metal atoms on the contact surface to diffuse and combine in a solid state, thereby achieving the welding of the wire harness and the terminal.

[0012] During the welding process between the metal wires and terminals of the wire harness, the controller controls the electromagnet to be energized again to generate magnetism. The two sets of electromagnets are set with opposite poles facing each other. The inner diameter of the circular cavity formed after the initial splicing of the half-set rubber cylinder is smaller than the outer diameter of the wire harness. Under the mutual attraction of the electromagnets, the half-set rubber cylinder is squeezed and spliced ​​together to complete the clamping of the wire harness. This facilitates the pull-out test of the welded wire harness and ensures the welding quality between the metal wires and terminals of the wire harness.

[0013] Under the same welding process parameters, the larger the cross-sectional area of ​​the wire, the longer the welding time is usually, and the more heat is output from the welding area. The heat-conducting copper rod is flush with the welding table surface, which can directly conduct the heat of the welding area and conduct it outward. The soft iron block follows the movement of the clamping block, reducing the distance between itself and the heat-conducting copper rod. The heat-resistant bar magnet magnetizes the soft iron block above it. The soft iron block and the heat-resistant bar magnet are set with opposite poles. The heat-conducting copper rod uses the heat conducted out to heat the soft iron block. After the soft iron block is heated, its own magnetization intensity decreases, and the magnetic field weakens accordingly. The magnetic field strength between the heat-resistant bar magnet and the soft iron block weakens accordingly, so that the sliding spring can pull the terminal through the metal wire at a faster rebound speed. The terminal is pulled out from between the heat-resistant rubber layers. On the one hand, the welding area is unloaded, and on the other hand, the welding quality between the metal wire and the terminal can be tested by pull-out test (hereinafter referred to as "pull test").

[0014] The smaller the cross-sectional area of ​​the conductor, the shorter the welding time is usually, and the less heat is output from the welding area. This results in less heat being heated by the thermally conductive copper rod to the soft iron block, and a stronger magnetic field between the heat-resistant strip magnet and the soft iron block. Consequently, the sliding spring pulls the terminal through the metal conductor at a slower rebound speed, preventing the thin wire bundle from being torn apart under faster pulling speed and intensity, thus ensuring the safety and reliability of the test.

[0015] Specifically, a controller is provided on the side wall of the conductor platform.

[0016] The controller is electrically connected to the drive motor, the connecting electromagnet, and the sliding electromagnet.

[0017] The beneficial effects achieved by this solution using the above structure are as follows:

[0018] Compared with existing technologies, this solution combines a plug-in type fixed-end mechanism with a thermomagnetic type positioning mechanism. Through the setting of drive components, guide components, clamping components, sliding drive components, wire clamping components, and demagnetizing components, heat from the welding area can be discharged. The heat-conducting copper rod heats the magnetized soft iron block, weakening the magnetic field strength between the soft iron block and the heat-resistant bar magnet. This allows the sliding drive spring to automatically adjust the pulling speed and strength between the wire harness and the terminal according to the diameter of the wire harness. This enables small-diameter wire harnesses to complete the pull test under low strength and low speed, while large-diameter wire harnesses can complete the pull test under high strength and high speed. It also enables automatic regroup welding of terminals, thereby ensuring the safety and reliability of the test. Attached Figure Description

The guide post 18 is symmetrically arranged between the lead frame 1 and the welding platform 3, and the guide post 18 is rotatably arranged between the lead frame 1 and the welding platform 3.

The heat-resistant magnetic column 35 is located on the side of the soft iron block 30 near the heat-conducting copper rod 27. A magnetic shielding layer is provided on the outside of the heat-resistant magnetic column 35.

[0038] A controller 31 is installed on the side wall of the conductor platform 1.

[0039] The controller 31 is electrically connected to the drive motor 6, the coupling electromagnet 25 and the sliding electromagnet 33 respectively.

[0040] In actual use, initially, the guide spring 12 is in an extended state, and the sliding drive spring 20 is initially in a compressed state. Multiple sets of terminals are inserted between the heat-resistant rubber layers 15 inside the clamping box 14. The terminals are clamped inside the clamping box 14 by the deformation of the heat-resistant rubber layers 15.

[0041] The controller 31 controls the activation of the electromagnet 25. The electromagnet 25 is energized and generates magnetism. The electromagnets 25 are set with the same pole. The electromagnets 25 repel each other due to the repulsive magnetic field generated and move in opposite directions. The electromagnet 25 pushes the sliding block 19 through the arc rod 22. The sliding block 19 drives the guide post 18 to rotate by the elastic deformation of the sliding drive spring 20. The circular cavity formed by the two sets of half rubber tubes 24 is opened. The wire harness is placed between the half rubber tubes 24. The end of the wire harness away from the half rubber tube 24 is placed on the bottom wall of the arc groove 2. Then the electromagnet 25 is de-energized and demagnetized. The sliding drive spring 20 elastically resets and drives the sliding block 19 to rotate through the guide post 18. The sliding block 19 drives the wire clamping block 23 to move relative to each other through the arc rod 22. The wire clamping block 23 drives the half rubber tube 24 to clamp the wire harness.

[0042] The controller 31 controls the start of the sliding electromagnet 33. The sliding electromagnet 33 is energized and generates magnetism. The sliding electromagnet 33 and the sliding magnetic block 32 are set with opposite poles. The sliding electromagnet 33 is fixed to the side wall of the welding table 3 and magnetically attracts the sliding magnetic block 32. The sliding magnetic block 32 uses the deformation of the sliding spring 20 to drive the sliding block 19 to slide along the guide post 18. The sliding block 19 drives the wire clamping block 23 to move closer to the welding table 3 through the arc rod 22. The wire clamping block 23 drives the wire harness to move to the welding table surface of the welding table 3 through the half rubber sleeve 24. At this time, the metal wire of the wire harness is located on the upper wall of the terminal.

[0043] The ultrasonic welding equipment is moved to one side of the welding table 3. The ultrasonic welding equipment presses the metal wire and terminal down onto the table surface of the welding table 3. Under the pressure of the ultrasonic welding equipment, the wire harness is pulled out from between the half rubber cylinders 24 to avoid excessive pulling of the wire harness. The bottom wall of the clamping box 14 is in contact with the bottom wall of the welding groove 34, and the bottom wall of the terminal is in contact with the table surface of the welding table 3. The ultrasonic welding equipment generates heat through high-frequency vibration and friction, causing the metal atoms on the contact surface to diffuse and combine in the solid state, thereby achieving the welding of the wire harness and the terminal.

[0044] After the wire harness metal wires and terminals are pressed together on the welding table 3, the controller 31 controls the electromagnet 25 to be energized and generate magnetism. The electromagnet 25 is set with opposite poles. The inner diameter of the cavity formed by the splicing of the half rubber cylinders 24 is smaller than the outer diameter of the wire harness. Under the mutual attraction of the electromagnets 25, the half rubber cylinders 24 are squeezed and spliced ​​together to complete the clamping of the wire harness. This facilitates the pull-out test of the welded wire harness and ensures the welding quality between the wire harness metal wires and terminals.

[0045] Under the same welding process parameters, the larger the cross-sectional area of ​​the wire, the longer the welding time is usually, and the more heat is output from the welding area. The heat-conducting copper rod 27 conducts heat out of the welding area. The soft iron block 30 moves with the clamping block 23 and reduces the distance between itself and the heat-conducting copper rod 27. The heat-resistant bar magnet 29 magnetizes the soft iron block 30 above it. The soft iron block 30 and the heat-resistant bar magnet 29 are set with opposite poles. The heat-conducting copper rod 27 uses the heat it conducts to heat the soft iron block 30. After the soft iron block 30 is heated, the magnetic field weakens. The magnetic field strength between the heat-resistant bar magnet 29 and the soft iron block 30 weakens accordingly, so that the sliding spring 20 can pull the terminal through the metal wire at a faster rebound speed. The terminal is pulled out from between the heat-resistant rubber layers 15.

[0046] The smaller the cross-sectional area of ​​the conductor, the shorter the welding time is usually, and the less heat is output from the welding area. This results in less heating heat from the thermally conductive copper rod 27 to the soft iron block 30, and a stronger magnetic field between the heat-resistant strip magnet 29 and the soft iron block 30. Consequently, the sliding spring 20 pulls the terminal through the metal conductor at a slower rebound speed.

[0047] After the terminal is pulled out from the clamping box 14 by the metal wire, the controller 31 controls the electromagnet 25 to start. The electromagnet 25 is energized and generates the same polarity magnetism. The clamping blocks 23 move in opposite directions, taking out the welded wire bundle and terminal from the clamping blocks 23 and the arc groove 2, and placing the next set of wire bundles. This not only completes the unloading of the welding area, but also realizes the above-mentioned welding quality pull test. It can also prevent the thin wire bundle from being torn off under high pulling speed and strength, thereby ensuring the safety and reliability of the test.

[0048] Subsequently, the controller 31 controls the drive motor 6 to start, and the drive motor 6 drives the drive frame 7 to rotate through the power end. The drive frame 7 drives the sliding plate 11 to rotate through the guide ring disk 9. The sliding plate 11 drives the next set of terminals to enter the table surface of the welding station 3 through the clamping box 14, waiting for the ultrasonic welding equipment to perform the downward welding operation. The above operation can be repeated for the next use.

In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
