Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a welding tool. Background Art

[0002] Lithium batteries are widely used in the electric vehicle and energy storage industries due to their high energy density, long life, good safety performance, and low pollution. The battery assembly process includes welding the top cover to the battery housing. There are two existing methods for welding battery top covers: vertical laser welding and side laser welding. Vertical welding refers to welding along the joint from top to bottom or bottom to top, with the weld angle at 90° (vertical upward) or 270° (vertical downward). Side welding refers to welding the sides of two workpieces together. Its welding position is mainly located on the side of the workpiece, which is different from the vertical welding position of vertical welding. From a technical perspective, vertical welding is time-saving and efficient, but there may be light leakage in the welding. Side welding has higher welding quality but takes longer. Currently, the welding tooling used for side welding and vertical welding is separate, and it needs to be switched according to needs before each welding. Utility Model Content

[0003] The purpose of the utility model is to provide a welding tool, which connects two welding mechanisms in different directions together through a bracket. During production, vertical welding or side welding can be freely selected according to welding requirements without switching welding tools, thereby simplifying the welding process.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The utility model discloses a welding tool, comprising a support, a rotating mechanism installed on the support, a bracket connected to the rotating mechanism, and two welding mechanisms arranged at different positions on the bracket. The welding mechanism comprises a clamping part for clamping a battery block and a telescopic cylinder connecting the clamping part and the bracket.

[0006] A further solution: the clamping portion includes first reference plates placed opposite to each other and a first clamping cylinder driving the two first reference plates to move relative to each other; the non-telescopic end of the first clamping cylinder is connected to the bracket.

[0007] A further solution: the clamping part also includes a second reference plate placed in a relative position and a second clamping cylinder that drives the two second reference plates to move relative to each other; the first reference plate and the second reference plate together form a receiving cavity for placing the battery; the non-retractable end of the second clamping cylinder is connected to the bracket.

[0008] A further solution: the two welding mechanisms are arranged perpendicular to each other.

[0009] A further solution: the welding mechanism further includes an L-shaped plate arranged between the clamping portion and the telescopic cylinder; the telescopic cylinder and the clamping portion are respectively installed at two extending ends of the L-shaped plate.

[0010] A further solution: the welding mechanism further comprises an extension plate slidably connected to the first reference plate, and the extension plate can slide back and forth in a limited manner along the length direction of the first reference plate.

[0011] A further solution: the welding mechanism further includes a longitudinal support block arranged between the first reference plate and the second reference plate.

[0012] A further solution: the longitudinal support block is detachably connected to the L-shaped plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This new design integrates both vertical and side welding mechanisms on a single support. Before welding, users can select the appropriate welding mechanism based on their needs, eliminating the need to switch tooling and simplifying the welding process. The vertical welding mechanism is ideal for quick welding with low-quality requirements, while the side welding mechanism is ideal for high-quality welding. Furthermore, the welding angle can be adjusted by adjusting the rotating mechanism, while the welding distance can be adjusted by adjusting the telescopic cylinder, ensuring precise workpiece positioning and improving welding quality.

[0020] See also Figures 1-2 A welding tool comprises a support 1, a rotating mechanism 3 mounted on the support 1, a bracket 4 connected to the rotating mechanism 3, and two welding mechanisms 2 arranged on the bracket 4. The welding mechanism 2 comprises a clamping portion 21 for clamping a battery block and a telescopic cylinder 22 connecting the clamping portion 21 and the bracket 4. The two welding mechanisms 2 are perpendicular to each other, one extending upward and referred to as the vertical welding mechanism, and the other extending outward and referred to as the side welding mechanism. As the rotating mechanism 3 rotates, the vertical welding mechanism clamps the battery and rotates circumferentially with the rotating mechanism 3 as the central axis, while the side welding mechanism clamps the battery and rotates with the rotating mechanism 3 as the center point. In addition, the telescopic cylinder 22 of the vertical welding mechanism is perpendicular to the central axis of the rotating mechanism 3, which can adjust the height of the clamped battery during vertical welding; the telescopic cylinder 22 of the side welding mechanism is parallel to the central axis of the rotating mechanism 3, which can adjust the horizontal position of the clamped battery during side welding. Through the arrangement of the side welding mechanism and the vertical welding mechanism, and the drive of the rotating mechanism 3, precise positioning of the workpiece is achieved, and the welding quality is improved.

[0021] Furthermore, the clamping portion 21 includes first reference plates 211 positioned opposite each other and a first clamping cylinder 212 that drives relative movement between the two first reference plates 211. The non-retractable end of the first clamping cylinder 212 is connected to the bracket 4. The clamping portion 22 also includes second reference plates 213 positioned opposite each other and a second clamping cylinder 214 that drives relative movement between the two second reference plates 213. The first and second reference plates 211, 213 together form a rectangular storage cavity for accommodating batteries. The non-retractable end of the second clamping cylinder 214 is mounted on one end face of the bracket 4.

[0022] Furthermore, the welding mechanism 2 further includes an L-shaped plate 23 provided between the clamping portion 21 and the telescopic cylinder 22 ; the telescopic cylinder 22 and the clamping portion 21 are respectively mounted on two right-angled sides of the L-shaped plate 23 .

[0023] Furthermore, the bracket 4 is a cubic box structure, with its two vertical surfaces serving as mounting end surfaces for the vertical and side welding mechanisms. Corresponding slots are provided on the mounting end surfaces for the welding mechanisms to pass through. The telescopic cylinder 22 and L-shaped plate 23 are both mounted within the cubic box. The non-telescopic end of the telescopic cylinder 22 is fixedly connected to the inner wall of the cubic box.

[0024] Furthermore, the welding mechanism 2 includes an extension plate 24 slidably connected to the first reference plate 211. The extension plate 24 can slide back and forth in a limited manner along the length of the first reference plate 211. For larger batteries, the extension plate 24 can be slid out from the bottom of the first reference plate 221 to provide support for the long sides of the battery.

[0025] Furthermore, the welding mechanism 2 also includes a longitudinal support block 25 arranged between the first reference plate 211 and the second reference plate 213. The longitudinal support block 25 is detachably connected to the L-shaped plate 23. The longitudinal support blocks 25 of different lengths can be replaced according to the width of the battery to provide support for the wide side of the battery.
