Description

Technical Field

[0001] This utility model relates to the field of wire harness welding technology, specifically a low-voltage wire harness soldering structure. Background Technology

[0002] In modern industrial production, wire harness soldering, as a key process to ensure the reliability of electrical connections, is widely used in many fields such as electronics, automobiles, and aerospace. With the rapid development of automation technology, automated soldering technology has emerged, improving production efficiency and the stability of soldering quality to a certain extent. However, current automated soldering technology still has significant shortcomings when it comes to wire harness soldering. On the one hand, existing automated soldering equipment lacks an effective automatic adjustment mechanism for wire harnesses of different specifications, materials, and structures. The wire diameter, insulation characteristics, and thermal conductivity of the metal conductors vary greatly, requiring precise matching of parameters such as temperature, time, and solder supply during the soldering process. However, existing equipment usually operates based on preset fixed parameters, making it difficult to adjust dynamically and in real time according to the actual situation of the wire harness. This leads to problems such as melting or insulation damage when soldering thin wire harnesses, and weak or incomplete soldering when soldering thick wire harnesses. Especially in scenarios where multiple specifications of wire harnesses are produced together, frequent manual intervention severely restricts production efficiency and increases production costs. On the other hand, reliable clamping and fixing of wire harnesses is crucial in the field of wire harness soldering. Stable clamping ensures that wire harnesses maintain the correct position and orientation during soldering, thereby guaranteeing the accuracy of the soldering position and the consistency of the soldering quality. However, the clamping and fixing devices equipped with existing automatic soldering equipment are mostly general-purpose but lack specificity, making it difficult to adapt to wire harnesses with complex shapes and structures, such as multi-stranded wires, irregularly shaped wire harnesses, or wire harnesses with special protective layers. In actual operation, wire harness slippage and deformation are prone to occur, affecting the soldering effect. At the same time, existing clamping devices also have significant shortcomings in terms of ease of adjustment and flexibility, failing to quickly adapt to changes in the size and shape of different wire harnesses, further hindering the improvement of production efficiency. Therefore, developing a soldering technology that can automatically adjust and has efficient wire harness clamping and fixing functions has become a key problem that urgently needs to be solved in the current wire harness soldering field.

[0022] 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.

[0023] Please see Figures 1-3This utility model provides a technical solution: a low-voltage wire harness soldering structure for soldering wire harness 5, wherein the wire harness 5 is connected to a terminal block 51, and the soldering structure is used to weld the wire harness 5 and the terminal block 51 together, comprising: a workbench 1, the workbench 1 being used to support the remaining components of the structure, characterized in that it further comprises:

[0024] The sliding device 2 facilitates the installation of the wire harness 5 on the clamping device 3. When the clamping device 3 is moved away from the welding device 4, the sliding device 2 further facilitates the installation of the wire harness 5 within the clamping device 3. It is mounted on the worktable 1. The sliding device 2 includes a first sliding plate 21 and a second sliding plate 22. The first sliding plate 21 supports the clamping device 3, and the second sliding plate 22 supports the welding device 4. Both the first and second sliding plates 21 are mounted on the worktable 1. The first sliding plate 21 has a first slider 25, which supports the clamping device 3. The first slider 25 can move along the first sliding plate 21 under the influence of the lead screw 24. The second sliding plate 22 has a second slider 26, which slides along the second sliding plate 22 under the influence of the lead screw 24. This is used to drive the welding device 4 to move synchronously. The first slide plate 21 and the second slide plate 22 are both provided with limit grooves 23 and lead screws 24. The limit grooves 23 are used to limit the first slider 25 and the second slider 26. The lead screws 24 are used to drive the first slider 25 and the second slider 26 to move respectively. There are four limit grooves 23 and two lead screws 24. The second slider 26 is provided with a third slide plate 27 and a third slider 28. The third slider 28 is used to support the support member 41. The moving direction of the welding device 4 supported by the second slider 26 and the third slider 28 is perpendicular. Under the drive of the third slider 28, the electromagnetic head 44 and the solder needle 47 approach the connection between the wire harness 5 and the terminal 51, thereby facilitating the welding device 4 to weld the wire harness 5.

[0025] It is used to weld the wire harness 5 and the terminal block 51 together, and the workbench 1 supports all other components. When the sliding device 2 is in operation, the lead screw 24 drives the first slider 25 to move on the first slide plate 21, which can move the clamping device 3 carried by the first slider 25 away from the welding device 4. At this time, because there is enough space, it is convenient to connect the terminal block 51 to the wire harness 5 and then install it onto the clamping device 3. The limiting groove 23 limits the movement of the first slider 25. Afterwards, the lead screw 24 drives the first slider 25 to move, moving the clamping device 3 and the wire harness 5 and terminal block 51 on it to a position close to the welding device 4; at the same time, the lead screw 24 drives the second slider 26 to slide on the second slide plate 22, so that the welding device 4 carried by the second slider 26 moves synchronously, and the limiting groove 23 limits the movement of the second slider 26. Next, the third slider 28 moves on the third slide plate 27. Because the second slider 26 and the third slider 28 drive the welding device 4 to move in a perpendicular direction, the electromagnetic head 44 and solder needle 47 of the welding device 4 can be driven to accurately approach the connection between the wire harness 5 and the terminal 51, and finally complete the welding operation of the two.

[0026] A clamping device 3 is mounted on the sliding device 2. The clamping device 3 includes a support slide plate 33 connected to the first slider 25. The support slide plate 33 supports the movable plate 34, which is embedded in one side of the support slide plate 33. An air passage is provided inside the support slide plate 33, connected to an air pump for pushing the movable plate 34 up and down. The movable plate 34 is mounted on the support slide plate 33 and is in an inverted L-shape. A pressure plate 36 is connected to the movable plate 34, and a connecting plate 35 is connected between the movable plate 34 and the pressure plate 36. The pressure plate 36 presses and fixes the wire harness 5. When the movable plate 34 moves downward, it drives the pressure plate 36 to clamp the wire harness 5 via the connecting plate 35. The bearing plate 32 and the pressure plate 36 contact each other to clamp the wire harness 5. The clamping device 3 also includes... The first slider 25 includes a support plate 31, which is used to connect the support plate 32. The support plate 31 is connected to the support plate 32, and the support plate 32 is connected to the support slide plate 33. The support slide plate 33 can drive the moving plate 34 to move up and down. The moving plate 34 is provided with a connecting plate 35 for connecting with the pressure plate 36. The support bridge 37 is provided on one side of the support plate 32. The support bridge 37 is used to connect the wire harness 5 and the terminal 51. The support bridge 37 is provided with a snap-fit ​​plate 371 for snapping the wire harness 5. The snap-fit ​​plate 371 has a snap-fit ​​groove for snapping the wire harness 5, and a terminal connector 372 for connecting the terminal 51. The terminal connector 372 is also provided with an insertion rod for inserting the terminal 51 for fixing.

[0027] The wire harness 5 is inserted into the slot of the clamping plate 371 on the support bridge 37, and the terminal 51 is fixed by the insertion rod of the terminal connector 372. Then, the clamping device 3 operates, and the air pump connected to the air passage inside the support slide plate 33 starts, pushing the moving plate 34 downwards on the support slide plate 33. The inverted L-shaped moving plate 34, through the connecting plate 35, drives the pressure plate 36 downwards, cooperating with the bearing plate 32 to press and fix the wire harness 5. The support plate 31 provides support for the bearing plate 32, and the support slide plate 33 supports the moving plate 34. Next, the lead screw 24 drives the first slider 25 to move the clamping device 3, wire harness 5, and terminal 51 closer to the welding device 4. Simultaneously, the lead screw 24 drives the second slider 26 to move the welding device 4 synchronously, and the limiting groove 23 limits the second slider 26. Finally, the third slider 28 moves on the third slide plate 27, driving the electromagnetic head 44 and solder needle 47 of the welding device 4 precisely close to the connection point, completing the welding.

[0028] Welding device 4, connected to sliding device 2, includes a battery box 43 and solder needles 47. The battery box 43 is used to energize the wire harness 5, and the solder needles 47 are used to solder the wire harness 5 in conjunction with the battery box 43. Welding device 4 includes a support member 41 mounted on the third slider 28. The support member 41 supports the remaining structure of welding device 4. An electromagnetic connecting bridge 42 and a welding machine connecting bridge 45 are connected to the support member 41. The electromagnetic connecting bridge 42 is connected to the battery box 43, and the welding machine connecting bridge 45 is connected to the solder needles 47. A fixed connecting plate 46 is provided between the welding machine connecting bridge 45 and the solder needles 47. One side of the fixed connecting plate 46 is provided with... The rotating shaft can adjust the angle of the solder needles 47. One end of the rotating shaft is connected to the welding machine connecting bridge 45. The rotating shaft allows the fixed connecting plate 46 to rotate. The battery box 43 is equipped with at least two electromagnetic heads 44. The spacing between all electromagnetic heads 44 matches the diameter of the wire harness 5. The second slider 26 can replace the wire harness 5 being welded by the welding device 4 when it moves. When the third slider 28 slides on the third slide plate 27, it is used to approach the clamping device 3 to insert the two electromagnetic heads 44 into the upper and lower sides of the wire harness 5 and the terminal 51. The solder needles 47 solder the connection between the wire harness 5 and the terminal 51.

[0029] The lead screw 24 drives the second slider 26 to move the welding device 4 synchronously. The movement of the second slider 26 allows for the replacement of the wire harness 5 to be welded. The limiting groove 23 limits the movement of the second slider 26. Next, the third slider 28 slides on the third slide plate 27, causing the support member 41 on the third slider 28 and the rest of the welding device 4 to move closer to the clamping device 3. This allows the two electromagnetic heads 44 on the battery box 43 to be inserted into the upper and lower sides of the wire harness 5 and the terminal block 51, with the spacing of the electromagnetic heads 44 matching the diameter of the wire harness 5. The support member 41 supports structures such as the electromagnetic connecting bridge 42 and the welding machine connecting bridge 45. The electromagnetic connecting bridge 42 connects to the battery box 43, and the welding machine connecting bridge 45 connects to the solder needles 47 via a fixed connecting plate 46. A rotating shaft on one side of the fixed connecting plate 46 is connected to the welding machine connecting bridge 45 and can rotate to adjust the angle of the solder needles 47. Finally, the battery box 43 energizes the wire harness 5, and the solder needles 47, in conjunction with the battery box 43, solder the connection between the wire harness 5 and the terminal block 51, completing the welding operation.

[0030] The first slider 25 is also equipped with an air jet pipe 6. During the soldering process, the air jet pipe 6 blows air onto the soldering area to accelerate the solidification of liquid solder. In addition, it can blow the fumes generated by soldering toward the absorption device 7, which absorbs the fumes. The air jet pipe 6 is used to spray air onto the wire harness 5. The worktable 1 is equipped with the absorption device 7, which is used to absorb the air spray from the wire harness 5.

[0031] When using the low-voltage wire harness soldering structure, firstly, the sliding device 2 is activated, and the lead screw 24 drives the first slider 25 to move along the limiting groove 23 of the first slide plate 21, so that the clamping device 3 carried on the first slider 25 is moved away from the soldering device 4, providing sufficient space for wire harness installation. At this time, the wire harness 5 is inserted into the slot of the snap-fit ​​plate 371 on the support bridge 37, and the terminal 51 is fixed by the insertion rod of the terminal connector 372, completing the initial positioning.

[0032] Next, the clamping device 3 operates: the air pump connected to the air passage inside the support slide plate 33 is started, pushing the movable plate 34 embedded in the support slide plate 33 to move downward; the inverted L-shaped movable plate 34 drives the pressure plate 36 to move downward through the connecting plate 35, and cooperates with the bearing plate 32 to squeeze and fix the wire harness 5, wherein the support plate 31 provides support for the bearing plate 32, and the support slide plate 33 supports the movable plate 34.

[0033] Subsequently, the sliding device 2 adjusts its position again: the lead screw 24 drives the first slider 25 to move the clamping device 3 and the fixed wire harness 5 and terminal block 51 closer to the welding device 4; at the same time, the lead screw 24 drives the second slider 26 to slide along the limiting groove 23 of the second slide plate 22, so that the welding device 4 moves synchronously, and the wire harness 5 to be welded can be switched by the movement of the second slider 26.

[0034] Afterwards, the welding device 4 is precisely aligned: the third slider 28 slides on the third slide plate 27 and its movement direction is perpendicular to the second slider 26, which drives the support member 41 on the third slider 28 and the rest of the welding device 4 to approach the clamping device 3; the electromagnetic connecting bridge 42 carried by the support member 41 is connected to the storage box 43, so that the two electromagnetic heads 44 on the storage box 43 are spaced and matched with the diameter of the wire harness 5 and plugged into the upper and lower sides of the wire harness 5 and the terminal 51; at the same time, the welding machine connecting bridge 45 is connected to the solder needle 47 through the fixed connecting plate 46, and the rotating shaft on one side of the fixed connecting plate 46 is connected to the welding machine connecting bridge 45, which can rotate and adjust the angle of the solder needle 47 to align with the welding point.

[0035] Finally, welding and auxiliary operations are performed: the battery box 43 is energized to the wire harness 5, and the solder needle 47 cooperates to complete the soldering at the connection between the wire harness 5 and the terminal 51; during the soldering process, the air jet pipe 6 on the first slider 25 blows air to the welding part to accelerate the solidification of liquid solder, and at the same time blows the smoke towards the absorption device 7 on the workbench 1, where the absorption device 7 absorbs the smoke, and finally completes the entire welding operation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
