Description

Technical Field

[0001] This utility model relates to the field of battery laser spot welding technology, specifically a battery laser spot welding fixture. Background Technology

[0002] Battery laser spot welding fixtures, as an important component of automated laser welding production lines, are mainly used to fix and position battery components (such as electrode sheets, battery casings, etc.) to be welded, so as to ensure that the laser beam can be accurately focused on the welding point, thereby achieving high-precision welding and ensuring the reliability and consistency of the welding.

[0003] In laser welding, the laser beam interacts with the battery material, generating high temperatures to melt the material and achieve welding. During this process, the melting and solidification of the material, as well as the impact force of the laser beam, generate vibrations. These vibrations can cause subsequent battery positions to shift, leading to welding position deviations or poor welding. Furthermore, the more batteries to be welded, the greater the shift angle and position of subsequent batteries become, requiring continuous adjustments. This adjustment process is time-consuming and labor-intensive, reducing production efficiency. Therefore, we propose a novel laser spot welding fixture for batteries to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a battery laser spot welding fixture, which solves the problem that during laser welding, the interaction between the laser beam and the battery material generates high-temperature melting of the material to achieve welding. In this process, the melting and solidification of the material, as well as the impact force of the laser beam, produce vibrations. These vibrations can cause subsequent battery positions to shift, leading to welding position deviations or poor welding. Furthermore, the more batteries to be welded, the greater the shift angle and position of subsequent batteries become, requiring continuous adjustments. This adjustment process is time-consuming and labor-intensive, reducing production efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] This application provides a battery laser spot welding fixture, which solves the problem that during laser welding, the interaction between the laser beam and the battery material generates high-temperature melting of the material to achieve welding. In this process, the melting and solidification of the material, as well as the impact force of the laser beam, produce vibrations. These vibrations can cause subsequent battery positions to shift, leading to welding position deviations or poor welding. Furthermore, the more batteries to be welded, the greater the shift angle and position of subsequent batteries become, requiring continuous adjustments. This adjustment process is time-consuming and labor-intensive, reducing production efficiency.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] This utility model discloses a battery laser spot welding fixture.

[0020] According to the appendix Figures 1 to 4 As shown, the device includes a workbench 1, and a clamping and fixing mechanism 2 is provided on the top of the workbench 1. The clamping and fixing mechanism 2 includes a fixing block 201, a top block 202, a first slider 203, a lifting cylinder 204, and a pressure plate 205. Multiple sets of fixing blocks 201 are equidistantly fixedly installed on the top of the workbench 1. Multiple sets of top blocks 202 are slidably connected to the top of the workbench 1. The ends of the fixing blocks 201 and the top blocks 202 abut against each other. The first slider 203 is slidably connected to the outer surface of the workbench 1. The lifting cylinder 204 is located at the top of one end of the first slider 203. The pressure plate 205 is vertically slidably connected below the lifting cylinder 204. The output shaft of the lifting cylinder 204 is fixedly assembled with the pressure plate 205. The bottom of the pressure plate 205 abuts against the fixing blocks 201 and the top blocks 202.

[0021] When using the device, the battery to be spot-welded is placed inside the fixing block 201. The push-pull cylinder 209 is activated, pushing the second slider 208 to clamp the battery via the top block 202. The lifting cylinder 204 then moves the first slider 203 towards the position of the magnetic block 213, magnetically connecting the magnetic block 213 with the magnetic sheet 211, thus defining the position of the first slider 203. A conductive strip is placed on top of the battery, and the lifting cylinder 204 is activated again, causing the pressure plate 205 to slide downwards. This allows the pressure plate 205 to firmly fix the conductive strip to the top of the battery, enabling laser spot welding to begin. After spot welding is completed, the lifting cylinder 204 drives the pressure plate 205 to slide upwards. The lifting cylinder 204 then drives the first slider 203 to slide to one side, returning it to its original position. This disconnects the magnetic block 213 from the magnetic plate 211. The push-pull cylinder 209 then retracts outwards, causing the top block 202 to also retract outwards, releasing the clamping of the battery. The battery can then be removed, completing the laser spot welding of the battery.

[0022] A protective shell 206 is fixedly installed on the top of the workbench 1. A slide bar 207 is slidably connected inside the protective shell 206 and is fixedly connected to the top block 202.

[0023] The bottom of the slide bar 207 is fixedly connected to the second slider 208, and the side of the worktable 1 is fixedly installed with the push-pull cylinder 209. The second slider 208 is fixedly connected to the output end of the push-pull cylinder 209.

[0024] The top of the workbench 1 is symmetrically provided with a slide groove 210 along the central axis, and the first slider 203 is slidably connected inside the slide groove 210.

[0025] A magnetic block 213 is fixedly installed on one side of the slide 210, and a magnetic piece 211 is fixedly installed on one side of the first slider 203. The magnetic piece 211 is magnetically connected to the magnetic block 213.

[0026] The top of the first slider 203 is fixedly fitted with a support base 212, and the lifting cylinder 204 is fixedly fitted on the support base 212.

[0027] Connecting plates 214 are fixedly mounted on both sides of the pressing plate 205. The connecting plates 214 are slidably connected inside the support base 212. The output shaft of the lifting cylinder 204 is fixedly mounted to the pressing plate 205.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
