Description

Technical Field

[0001] This utility model relates to the field of stamping dies for battery structural components, specifically a stamping die for battery structural components with a laser cladding coating. Background Technology

[0002] Stamping dies are used to manufacture battery structural components, which typically include battery casings, battery brackets, connecting plates, etc., all of which are key components in battery packs. Laser cladding is a high-energy-density surface treatment technology that uses a high-power laser beam to melt the coating material and rapidly form an alloy layer or coating with the substrate surface, thereby improving the surface properties of the substrate material. Laser cladding can significantly improve the wear resistance, corrosion resistance, and oxidation resistance of the die surface, and is particularly suitable for improving the service life and performance of the die. During the stamping process, the die is prone to sticking to the metal material, especially when stamping battery casings with coatings. Laser cladding coatings can improve the anti-sticking properties of the die and reduce material adhesion to the die surface. By setting a laser cladding coating on the die surface, the wear resistance, corrosion resistance, and high-temperature resistance of the die are improved, thereby extending the service life of the die.

[0003] When existing laser cladding technology is applied to the coating of stamping dies for battery structural components, the die is usually placed on a worktable and the coating operation is carried out by the laser cladding mechanism. However, since the area of ​​coating required for stamping dies of different specifications of battery structural components varies, if the diameter of the spray nozzle used by the laser cladding equipment is too large, the coating material will be overly dispersed and it will be difficult to cover the target area, resulting in uneven coating thickness and material waste. If the diameter of the spray nozzle is too small, the cladding efficiency will be greatly reduced, and it will be difficult to quickly and evenly cover large areas of coating. Utility Model Content

[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please refer to Figure 1 , Figure 4 As shown, a stamping die for a battery structural component with a laser cladding coating includes a support platform 1. A die body 2 is placed at the center of the upper end of the support platform 1. A rotating platform 3 is fixedly installed at one side of the upper end of the support platform 1. A robotic arm mechanism 4 is fixedly installed at the upper end of the rotating platform 3. A first connecting plate 5 is fixedly connected to the lower end of the robotic arm mechanism 4. A second connecting plate 6 is bolted to the lower end of the first connecting plate 5. A laser cladding coating assembly 7 is fixedly connected to the lower end of the second connecting plate 6. A nozzle assembly 8 for easy disassembly, installation, and replacement of the nozzle is provided at the lower end of the laser cladding coating assembly 7. An installation groove 71 is opened on the inner wall of the lower end of the laser cladding coating assembly 7. A laser 72 is fixedly installed on the inner wall of the installation groove 71.

[0016] In a specific embodiment, by controlling the movement of the robotic arm mechanism 4, the first connecting plate 5, the second connecting plate 6, and the laser cladding coating component 7 connected to it are moved, so that the laser cladding coating component 7 can accurately reach the stamping mold of the battery structural component where the laser cladding coating processing is required. The robotic arm mechanism 4 can achieve multi-degree-of-freedom movement. This robotic arm mechanism 4 is common in the prior art and will not be described in detail here. When the laser cladding coating component 7 moves to the appropriate position, the laser 72 is activated. The high-energy laser beam generated by the laser 72 irradiates the nozzle assembly 8. On the surface of the stamping die for battery structural components, coating material is delivered to the area irradiated by a laser beam, causing the coating material to melt and solidify instantly on the surface of the stamping die, forming a laser cladding coating with specific properties. This aims to enhance the surface properties of the stamping die for battery structural components, such as wear resistance and corrosion resistance. Common laser cladding technologies for lasers 72 include GW Guanghui Laser YLLS-Clad-6000-W, Han's Laser KUKAKR30 / 8T5000mm, and Shandong Leishi LATECLAM-400s.

[0017] Please refer to Figure 1 , Figures 3 to 5 As shown, as a technical optimization of this utility model, the nozzle assembly 8 includes a spray cylinder 84. The upper end of the spray cylinder 84 is fixedly sleeved inside the mounting groove 71 of the laser cladding assembly 7. A paint valve 85 and an air inlet valve 86 are fixedly sleeved on the lower outer side of the spray cylinder 84. A second outer ring sleeve 87 is fixedly sleeved on the lower outer wall of the spray cylinder 84. Fixing blocks 88 are symmetrically fixedly connected to the outer wall of the second outer ring sleeve 87. Torque grooves 89 are opened inside the two fixing blocks 88. Telescopic cylinders 811 are fixedly installed on the upper ends of the two fixing blocks 88. A compression spring 815 is fixedly installed on the inner wall of the telescopic cylinder 811. A movable piece 814 is fixedly installed on the lower end of the compression spring 815. A pin rod 813 is fixedly connected inside the movable piece 814. The pin rod 813 is sleeved inside the compression spring 815 and slidably sleeved inside the telescopic cylinder 811. A handle 816 is fixedly connected to the upper end of the pin rod 813.

[0018] Furthermore, a sleeve 810 is fitted onto the lower part of the inner wall of the spray nozzle 84. A first outer ring sleeve 82 is fixedly fitted onto the outer wall of the sleeve 810. A torque locking block 83 is symmetrically fixedly connected to the outer wall of the first outer ring sleeve 82. An insertion hole 812 is opened inside one end of each of the two 93s. Both insertion holes 812 are rotatably fitted into the torque groove 89 of the fixing block 88. A nozzle 81 is fixedly connected to the lower end of the first outer ring sleeve 82. The pin rod 813 slides through the inside of the fixing block 88 and is inserted into the insertion hole 812.

[0019] In a specific embodiment, when the area of ​​the laser-clad coating on the stamping die of different battery structural components is different, nozzles 81 with different diameters are further replaced. Torque blocks 83 are symmetrically fixedly connected to the outer wall of the first outer ring 82. These torque blocks 83 cooperate with the torque grooves 89 on the fixed block 88. By rotating the first outer ring 82, the torque blocks 83 rotate within the torque grooves 89. At this time, the pin 813 inside the fixed block 88 is lifted by the torque blocks 83. The pin 813 is further retracted into the telescopic cylinder 811 by the compression spring 815 and moves upward. The movable piece 814 also moves inside the telescopic cylinder 811. When the pin 813 is inserted into the insertion hole 812 of the torque block 83, the compression spring 815 pushes the movable piece 814 to move by the elastic force. The pin 813 is then locked inside the fixed insertion hole 812, thereby realizing the replacement of the nozzle 81. By opening the paint valve 85 and the air inlet valve 86, the paint and gas are mixed in a predetermined ratio and then sprayed out from the nozzle 81. The laser 72 is activated, and the laser shines through the spray tube 84 onto the spraying area, instantly melting the paint and spraying it onto the surface of the battery structural component stamping die.

[0020] When this utility model is in use, if the area of ​​the laser-clad coating on the stamping die of different battery structural components is different, nozzles 81 of different diameters can be replaced. Torque blocks 83 are symmetrically fixed to the outer wall of the first outer ring 82. These torque blocks 83 cooperate with the torque grooves 89 on the fixed block 88. By rotating the first outer ring 82, the torque blocks 83 rotate within the torque grooves 89. At this time, the pin 813 inside the fixed block 88 is lifted by the torque blocks 83. The pin 813 is then compressed by the compression spring 815 and moves upward inside the telescopic cylinder 811. The movable piece 814 also moves inside the telescopic cylinder 811. When the pin 813 is inserted into the insertion hole 812 of the torque block 83, the compression spring 815 pushes the movable piece 814 to move through its elastic force. The pin 813 is then locked inside the fixed insertion hole 812, thereby realizing the replacement of the nozzle 81. By opening the paint valve 85 and the air inlet valve 86, the paint and gas are mixed in a predetermined ratio and then sprayed out from the nozzle 81. The laser 72 is activated, and the laser shines through the spray tube 84 onto the spraying area, instantly melting the paint and spraying it onto the surface of the battery structural component stamping die.
