A battery busbar welding height adjustable device

Abstract

This utility model discloses an adjustable welding height device for battery busbars, including an operating table, a welding table, a horizontal / vertical scaffold, and a laser welding mechanism. The laser welding mechanism is driven by a vertical lift to a fixed plate. A telescopic welding torch and a height-fixing rod are respectively installed on its symmetrical sides. During welding, the height-fixing rod moves close to the welding table. When the welding torch descends, a stop plate precisely abuts against a limiting step, forcibly constraining the final descent height of the welding torch. This design completely solves the problem of welding distance fluctuations caused by differences in busbar height, ensuring that the welding torch tip and the busbar surface maintain a constant reference distance, achieving consistent penetration depth and uniform and reliable weld joint thickness. Simultaneously, by adjusting the height of the limiting step, the initial distance between the welding torch stop position and the plate surface can be flexibly changed, thereby directly controlling the heat input point and achieving precise dynamic control of the welding penetration depth, significantly improving welding quality and process adaptability.

Description

Technical Field

[0001] This utility model relates to the field of battery busbar welding technology, and in particular to a battery busbar welding height adjustable device. Background Technology

[0002] In current battery busbar welding processes, to ensure consistent weld penetration and bonding strength, manual adjustment of the welding torch height or the use of complex sensor feedback systems is often relied upon. However, manual adjustment is inefficient and struggles to handle height fluctuations during continuous operation; while sensor solutions are costly, have poor anti-interference capabilities, and are prone to failure, especially in dusty and high-temperature welding environments. Existing mechanical limit devices, although simple in structure, cannot adapt to the height differences of the busbars on the welding platform. This results in a fixed welding torch stroke, leading to inconsistent weld penetration for busbars at varying heights, which in turn causes potential problems such as incomplete welds, over-melting, or insufficient connection strength. Utility Model Content

[0003] The purpose of this invention is to provide a battery busbar welding height adjustable device to solve the problem that the welding gun cannot adapt to the height difference of the busbar itself on the welding platform, resulting in a fixed downward stroke and inconsistent and unadjustable height.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a battery busbar welding height adjustable device, comprising an operating table, a welding table disposed on the operating table, a transverse frame disposed on the operating table, a longitudinal frame disposed on the operating table, and a laser welding mechanism disposed on the transverse frame. The laser welding mechanism includes a vertical lift, a fixed plate, a telescopic welding torch, a height-fixing rod, and a limiting platform. The vertical lift is disposed on the transverse frame and located above the welding table. The fixed plate is disposed on the side of the vertical lift near the welding table. The telescopic welding torch is disposed on one side of the fixed plate. The height-fixing rod is disposed on the side of the fixed plate symmetrical to the telescopic welding torch. The limiting platform is disposed on the height-fixing rod. A stop plate is provided on the side of the telescopic welding torch near the height-fixing rod. The stop plate abuts against the limiting platform to maintain the descent height of the telescopic welding torch.

[0005] Furthermore, the height-fixing rod includes a column and a universal ball seat located at the bottom of the column. The universal ball seat contains a universal ball, which abuts against the surface of the welding table.

[0006] Furthermore, the height-fixing rod also includes a connecting frame, the connecting frame having a sliding through hole, the column rod being disposed within the sliding through hole and slidably connected to the connecting frame, and a spring being disposed between the connecting frames, the spring being sleeved on the column rod.

[0007] Furthermore, the limiting platform is located between the universal ball seat and the connecting frame.

[0008] Furthermore, the limiting platform includes an adjusting collar and an extension platform, the adjusting collar being sleeved on the column rod, and the extension platform extending along the radial direction of the adjusting collar.

[0009] Furthermore, the adjusting collar has an opening on one side, and tightening plates are provided on both sides of the opening, with a bolt between the two tightening plates.

[0010] Furthermore, the bottom of the extension platform is provided with a reinforcing rib, and the side of the reinforcing rib is connected to the extension platform and the adjusting collar.

[0011] Furthermore, the transverse gantry, longitudinal gantry, and vertical elevator are driven to move by the drive motor or drive cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The height-fixing rod moves close to the surface of the welding table and adjusts its position according to the height of the manifold. When the telescopic welding torch descends for welding, its stop plate precisely abuts against the limiting step on the height-fixing rod, thus rigidly limiting and constraining the final descent height of the telescopic welding torch. This mechanism ensures that even if there are height differences in the manifold, the reference distance (i.e., welding height) between the tip of the telescopic welding torch and the surface of the manifold remains consistent. Combined with the stable welding height parameter, it can ensure that the penetration depth and weld joint thickness are uniform and reliable. At the same time, by adjusting the height of the limiting step, the initial welding distance between the welding torch stop position and the plate surface can be flexibly changed, thereby directly controlling the heat input point and achieving precise control of the welding penetration depth.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0023] like Figures 1 to 5 As shown, this utility model provides a battery busbar welding height adjustable device, including an operating table 1, a welding table 2 disposed on the operating table 1, a horizontal frame 11 disposed on the operating table 1, a vertical frame 12 disposed on the operating table 1, and a laser welding mechanism disposed on the horizontal frame 11. The laser welding mechanism includes a vertical lift 31, a fixed plate 32, a telescopic welding torch 33, a height-fixing rod 34, and a limiting platform 35. The vertical lift 31 is disposed on the horizontal frame 11 and located on the welding table 2. Above, the fixed plate 32 is located on the side of the vertical lifting machine 31 near the welding table 2, the telescopic welding gun 33 is located on one side of the fixed plate 32, the height-fixing rod 34 is located on the side of the fixed plate 32 symmetrical to the telescopic welding gun 33, the limiting platform 35 is located on the height-fixing rod 34, and the telescopic welding gun 33 is provided with a stop plate 36 on the side near the height-fixing rod 34. The stop plate 36 abuts against the limiting platform 35 to maintain the descent height of the telescopic welding gun 33.

[0024] The height-fixing rod 34 includes a column 341 and a universal ball seat 342 located at the bottom of the column 341. The universal ball seat 342 contains a universal ball 343 body, which abuts against the surface of the welding table 2. The universal ball seat 342 located at the bottom of the column 341 contains a universal ball 343 body that abuts against the surface of the welding table 2. This structure allows the column 341 to adapt to the micro-undulations or imperfect flatness of the surface of the welding table 2 when it moves. The low-friction free rolling characteristic of the ball ensures that the bottom of the column 341 always slides in close contact with the table surface, which improves the stability and reliability of the subsequent height control of the telescopic welding torch 33 and ensures that the position of the limit stage 35 truly reflects the table surface reference.

[0025] The height-fixing rod 34 also includes a connecting frame 344, which has a sliding through hole 345. The column rod 341 is disposed in the sliding through hole 345 and slidably connected to the connecting frame 344. A spring 346 is provided between the connecting frames 344 and is sleeved on the column rod 341. The column rod 341 of the height-fixing rod 34 is slidably connected to the connecting frame 344 through the sliding through hole 345, and a sleeve spring 346 is provided between them, which provides a constant upward preload. The force compels the universal ball 343 at the bottom of the column 341 to always press firmly against the welding table surface 2, and dynamically compensates for minor unevenness or particle interference on the table surface, ensuring the continuity of the height signal. The sliding through hole 345 itself constrains the column 341 to float only in a small range in the vertical direction, avoiding the impact of lateral swaying on positioning accuracy. The overall lightweight elastic floating structure greatly reduces the impact and wear risk of the column contacting the table surface, and improves the smoothness and long-term durability of the universal ball 343 during automatic movement.

[0026] The limiting platform 35 is located between the universal ball 343 seat 342 and the connecting frame 344, which facilitates the adjustment of the height of the limiting platform 35.

[0027] The limiting platform 35 includes an adjusting collar 351 and an extension platform 352. The adjusting collar 351 is sleeved on the column rod 341, and the extension platform 352 extends along an axis perpendicular to the adjusting collar 351. The limiting sleeve consists of the adjusting collar 351 and the vertical extension platform 352. The adjusting collar 351 is sleeved on the column rod 341 to provide fixed support for the main body. The extension platform 352 extends horizontally along the radial direction of the column rod 341, realizing the height adjustment function through the adjusting collar 351 and the load-bearing and blocking function through the extension platform 352. The extension platform 352 forms a horizontal, wide and sturdy blocking surface, which facilitates the precise contact of the welding torch stop plate 36 and evenly disperses the impact force, ensuring smooth movement of the device. The structural design is simple and efficient.

[0028] The adjusting collar 351 has an opening on one side, and a tightening plate 353 is provided on both sides of the opening. A bolt 354 is provided between the two tightening plates 353. When the bolt 354 is tightened, the tightening plate 353 strongly and radially clamps the opening, forming a high-strength rigid connection between the collar and the column rod 341. This effectively prevents slight displacement under welding vibration and ensures that the set limit height remains stable under harsh working conditions.

[0029] The bottom of the extension platform 352 is provided with a reinforcing rib 355, and the side of the reinforcing rib 355 is connected to the extension platform 352 and the adjusting collar 351. The reinforcing rib 355 at the bottom of the extension platform 352, which connects the platform surface and the collar, significantly increases the bending and torsional stiffness of the cantilever area of ​​the extension platform 352, providing a solid and non-deformable physical reference for welding torch height control.

[0030] The transverse gantry 11, longitudinal gantry 12, and vertical lift 31 are driven to move by the drive motor or drive cylinder. This multi-axis drive scheme provides the height-fixing rod 34 with precise and controllable movement in three-dimensional space, enabling it to not only follow the contours of the welding table 2 surface but also quickly reach and accurately position itself in the welding area according to process requirements. The diversity of drive sources provides optimized options for different working conditions, collectively supporting the reliable operation of the height-fixing rod 34 as a core height reference on the entire welding worktable.

[0031] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
