Detailed Implementation

[0022] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figures 1-3 As shown, the battery welding first piece tooling of this utility model embodiment includes: a base 1 and a pressure strip assembly 2.

[0024] The base 1 includes a top plate 11, which has multiple limiting grooves 12. The contours of the limiting grooves 12 are adapted to the contours of the battery welding components. The pressure strip assembly 2 includes a pressure rod 21 and a pressure strip 22. The first end of the pressure rod 21 is connected to the top plate 11, and the first end of the pressure strip 22 is connected to the second end of the pressure rod 21. At least one of the pressure rod 21 and the pressure strip 22 is rotatable relative to the top plate 11. There are multiple pressure strip assemblies 2, with one limiting groove 12 corresponding to at least one pressure strip assembly 2. The pressure strip assembly 2 has a first position and a second position. In the height direction of the base 1, in the first position, the pressure strip 22 is spaced apart from the limiting groove 12; in the second position, at least a portion of the pressure strip 22 abuts against the battery welding components.

[0025] Specifically, such as Figures 1-3As shown, the base 1 serves as the basic structure of the tooling, and its top is provided with a top plate 11, on which multiple limiting grooves 12 are distributed. The internal space of the limiting grooves 12 is designed to fit the shape of the battery welding component, so as to prevent relative movement between the battery welding component and the top plate 11 in the horizontal direction during the welding process.

[0026] As part of the pressure bar assembly 2, the pressure bar 21 transmits the applied pressure to the pressure bar 22, ensuring that the pressure bar 22 can firmly fix the battery welding components and prevent relative movement between the battery welding components and the top plate 11 in the vertical direction. The rotatable design of the pressure bar 21 or the pressure bar 22 improves operational flexibility, reduces personnel intervention, and enhances safety.

[0027] It is understood that at least one of the pressure rod 21 and the pressure strip 22 is rotatable relative to the top plate 11. The pressure rod 21 can be connected to the top plate 11 by means of threaded connection or shaft hole connection; or the pressure strip 22 can be connected to the top plate 11 by means of threaded connection or shaft hole connection; or both the pressure rod 21 and the pressure strip 22 can be connected to the top plate 11 and the pressure rod 21 respectively by means of threaded connection or shaft hole connection.

[0028] In other words, the pressure strip assembly 2 can be adjusted in position as needed to ensure that the battery welding components are firmly fixed. The use of multiple pressure strip assemblies 2 can be arranged axially or internally in the limiting groove at different positions, ensuring that each battery welding component can be stably fixed on the top plate 11 during the welding process, which improves welding efficiency, reduces manual intervention, and improves welding quality and safety.

[0029] In other words, the battery welding first piece tooling of this embodiment adopts a corresponding arrangement of multiple pressure strip assemblies 2 and multiple limiting grooves 12, enabling the tooling to perform multiple welding operations simultaneously, significantly improving welding efficiency. At the same time, the flexible adjustment of the pressure strip assemblies 2 reduces manual intervention, improving welding quality and safety.

[0030] In some embodiments, the plurality of limiting grooves 12 are divided into a first welding area 121 and a second welding area 122, wherein the length, width and depth of the first welding area 121 are different from at least one of the length, width and depth of the second welding area 122.

[0031] It should be noted that the battery welding components include the component to be welded from the positive electrode of the battery cell, the component to be welded from the negative electrode of the battery cell, the component to be welded from one another, or the component to be welded from one nickel sheet, as well as combinations of other different bonding materials.

[0032] In other words, depending on the different battery welding components, different welding areas can be set on the top plate 11, such as the first welding area 121 and the second welding area 122. And depending on the different lengths, widths and thicknesses of the battery welding components, the first welding area 121 and the second welding area 122 can adopt different lengths, widths and depths so as to match the corresponding types of battery welding components, improve the application scenarios of the tooling, and meet the requirements of multiple welding at one time, thereby improving welding efficiency and reducing the time for welding parameter verification.

[0033] In some embodiments, the top plate 11 is further provided with a protrusion, which is disposed in the limiting groove 12. The first end of the pressure rod 21 is connected to the protrusion, and the area defined between the protrusion and the side wall of the limiting groove 12 is adapted to the battery welding component.

[0034] Specifically, such as Figures 1-3 As shown, a protrusion is provided on the bottom wall of the limiting groove 12, and the first end of the pressure rod 21 is connected to the protrusion so that the pressure strip assembly 2 can be arranged closer to the battery welding parts, making it convenient to press the battery welding parts.

[0035] Optionally, multiple protrusions can be installed in a limiting groove 12, and the multiple protrusions can be arranged according to the contour of the battery welding component so that the area defined between the multiple protrusions and the side wall of the limiting groove 12 can be adapted to the battery welding component, thereby facilitating the welding of the battery welding component.

[0036] In some embodiments, the pressure strip assembly 2 further includes an elastic element 23, the first end of which is connected to the top plate 11, and the second end of which is connected to the pressure strip 22. In the second position, the pressure strip 22 abuts against the battery welding component under the elastic force of the elastic element 23.

[0037] Specifically, such as Figures 1-3 As shown, the first end of the elastic element 23 is connected to the top plate 11 by a fixing device (such as a bolt, a buckle, etc.), and the second end is connected to the pressure strip 22.

[0038] Understandably, when the pressure strip assembly 2 is in the second position, the elastic element 23 presses the pressure strip 22 against the battery welding component through its elasticity. Of course, the elasticity of the elastic element 23 can be adjusted according to the thickness of the battery welding component to ensure appropriate contact pressure between the pressure strip 22 and the component. Furthermore, during the welding process, the presence of the elastic element 23 can also alleviate vibrations generated between the battery welding component and the pressure strip 22, thereby reducing damage to the battery welding component and improving welding quality.

[0039] It should be noted that the elastic element 23 is usually made of high-strength springs or elastic rubber to ensure its elasticity and durability.

[0040] In some embodiments, the pressure strip assembly 2 further includes a gasket 24 connected to a second end of the pressure strip 22, the gasket 24 being located on the side of the pressure strip 22 adjacent to the top plate 11.

[0041] It is understandable that, such as Figures 1-3 As shown, the gasket 24 is located between the pressure strip 22 and the top plate 11, and can absorb and disperse the vibration and impact generated when the pressure strip 22 moves or is subjected to force. This reduces damage to the pressure strip 22 and the top plate 11 caused by vibration or impact, extends the service life of the tooling, and reduces welding quality problems caused by vibration during the welding process.

[0042] It should be noted that the gasket 24 can be made of rubber or plastic, and by adjusting the thickness of the gasket 24, the tooling can adapt to battery welding parts of different thicknesses to meet diverse production needs.

[0043] In some embodiments, the base 1 further includes a bottom plate 13 and a side plate 14. The side plate 14 is connected between the top plate 11 and the bottom plate 13. The top plate 11 is provided with a clearance hole 15, which penetrates the top plate 11 along the thickness direction and is arranged adjacent to the limiting groove 12.

[0044] Specifically, such as Figures 1-3 As shown, the base plate 13, serving as the foundation of the base 1, is typically made of high-strength materials, possessing sufficient rigidity and stability to withstand the weight of the entire fixture and vibrations during operation. The side plates 14 connect the base plate 13 and the top plate 11, forming a frame structure that enhances the overall stability and deformation resistance of the base 1. The base plate 13 and side plates 14 are typically connected by welding, bolting, or other fixing methods to ensure the structural stability of the entire base 1.

[0045] Understandably, the clearance holes 15 are located on the top plate 11, typically near the limiting groove 12, and their number and position are designed according to actual needs. The size and shape of the clearance holes 15 are usually matched to the equipment or tools that need to pass through, such as wires for welding equipment, gas pipelines, etc. The design of the clearance holes 15 avoids obstruction of these devices by the top plate 11, improving the convenience and efficiency of operation.

[0046] In other words, the top plate 11 is provided with multiple limiting grooves 12 and clearance holes 15. Each limiting groove 12 corresponds to a set of battery welding components, enabling multiple sets of welding to be performed simultaneously, which significantly improves production efficiency. The stable base 1 and the reasonable design of the clearance holes 15 allow the tooling to better adapt to automated operation, reducing the time and effort required for manual adjustment and improving the efficiency and safety of operation.

[0047] In some embodiments, the battery welding first piece tooling of this utility model embodiment further includes a top cup assembly 3, the top cup assembly 3 includes an adjusting rod 31, one end of the adjusting rod 31 is threadedly connected to the base plate 13, and in the height direction of the base 1, the clearance hole 15 is arranged correspondingly to the adjusting rod 31.

[0048] Specifically, such as Figure 3 The adjusting rod 31 is an adjustable-length rod, one end of which is threadedly connected to the base plate 13, and the other end extends toward the top plate 11. The threaded connection of the adjusting rod 31 to the base plate 13 allows the operator to rotate the adjusting rod 31 to adjust its height. In other words, the height adjustability of the adjusting rod 31 allows the operator to easily adjust it to accommodate different types of battery welding components, improving operational convenience and efficiency.

[0049] In some embodiments, the adjusting rod 31 has a mating groove 32 located on the side of the adjusting rod 31 adjacent to the top plate 11, and the mating groove 32 is used to abut against a portion of the battery welding component.

[0050] It is understandable that, such as Figures 1-3 As shown, the mating groove 32 is located at the top of the adjusting rod 31, near the top plate 11, and directly contacts the battery welding component. The shape of the mating groove 32 matches the shape of the battery welding component. The mating groove 32 partially abuts against the battery welding component, ensuring that the battery welding component is firmly fixed when pressure is applied by the adjusting rod 31, reducing the possibility of movement and improving welding quality.

[0051] In other words, when the adjusting rod 31 is adjusted to the appropriate height, the mating groove 32 abuts against the battery welding component, and the adjusting rod 31 applies appropriate pressure to firmly fix the battery welding component in the limiting groove 12.

[0052] In some other embodiments, the top cup assembly 3 further includes a cup body 33 having a mating groove 32. The cup body 33 is connected to the second end of the adjusting rod 31. The mating groove 32 is located on the side of the cup body 33 away from the adjusting rod 31 and is used to abut against a portion of the battery welding component.

[0053] It is understandable that, such as Figure 4 As shown, the cup body 33 is located at the second end of the adjusting rod 31, on the side away from the bottom plate 13 and close to the top plate 11. The shape of the cup body 33 is generally matched with the shape of the battery welding component, such as round, square or other specific shapes. The mating groove 32 abuts against a portion of the battery welding component, ensuring that the battery welding component is firmly fixed when pressure is applied by the adjusting rod 31, reducing the possibility of movement and improving welding quality.

[0054] In some embodiments, the top cup assembly 3 further includes a cup seat 34, which is fixedly connected to the base plate 13. The cup seat 34 is provided with a threaded hole, and the first end of the adjusting rod 31 is adapted to the threaded hole.

[0055] It is understandable that, such as Figures 1-3 As shown, the cup holder 34 is located on the base plate 13, usually near the mounting position of the adjusting rod 31. The cup holder 34 is connected to the base plate 13 by bolts, welding, or other fixing methods to ensure its stability and reliability. The cup holder 34 is provided with threaded holes for connecting to the first end of the adjusting rod 31.

[0056] The cup holder 34 is connected to the first end of the adjusting rod 31 via a threaded hole, ensuring the stability of the adjusting rod 31 and preventing loosening due to vibration or movement during operation. The threaded connection between the adjusting rod 31 and the cup holder 34 allows the height of the adjusting rod 31 to be adjusted by rotating it to accommodate battery welding components of different thicknesses or shapes. The fixed connection between the cup holder 34 and the base plate 13 enhances the structural stability of the entire fixture, preventing structural damage caused by vibration or movement. The design of the cup holder 34 makes the installation and adjustment of the adjusting rod 31 more convenient, improving the ease and efficiency of operation.
