[0033] With the rapid development of the new energy industry, the demand for battery modules such as lithium-ion batteries is constantly increasing, and the requirements for production efficiency and quality of battery modules are also becoming increasingly stringent. Laser welding technology, due to its high precision, high speed, and non-contact welding characteristics, is widely used in the welding process of battery modules. During the production of battery modules, because different models of battery modules vary in size, shape, and welding position, laser welding machines need to be equipped with different types of pressure heads to adapt to various welding needs. As a key component of the laser welding machine, the pressure head's function is to fix the battery module and ensure stability during the welding process. Existing laser welding machines typically use mechanical bolts to install the pressure head, and special tools must be used for disassembly and installation when replacing the pressure head.

[0034] The disassembly and assembly methods for pressure heads in related technologies are not only cumbersome but also require interrupting the welding process, resulting in prolonged equipment downtime. In the context of large-scale battery module production, frequent pressure head replacements significantly reduce overall production efficiency and increase production costs.

[0035] Please refer to Figures 1-3This embodiment provides a laser welding device, including a welding machine and a pressure head replacement device, the pressure head replacement device being installed on the welding machine. This laser welding device can effectively improve the aforementioned technical problems, enabling rapid pressure head replacement, shortening downtime, and improving production efficiency.

[0036] Please refer to Figure 1 This embodiment provides a pressure head replacement device including a pressure head body 10, a mounting base 20, and a blocking member 30. The mounting base 20 and the pressure head body 10 are detachably connected. The blocking member 30 is disposed on the mounting base 20 and is used to limit the pressure head body 10.

[0037] Specifically, the existing methods for disassembling and assembling pressure heads are not only cumbersome but also require interrupting the welding process, resulting in prolonged equipment downtime. In large-scale battery module production environments, frequent pressure head replacements significantly reduce overall production efficiency and increase production costs. To address this technical problem, the pressure head replacement device provided in this embodiment features a pressure head body 10 detachably connected to a mounting base 20, which is connected to a welding machine. A blocking member 30 is positioned on the mounting base 20 to limit the pressure head body 10. The welding machine moves the mounting base 20 to the surface of the battery module, causing the pressure head body 10 to press against the battery module, allowing the welding machine to perform laser welding. When the pressure head body 10 needs to be replaced, simply remove the blocking member 30 and then detach the pressure head body 10 from the mounting base 20. This rapid replacement reduces downtime and improves production efficiency.

[0038] In this embodiment, the mounting base 20 includes a base body 21 and a mating block 22. The base body 21 and the mating block 22 are connected, and the mating block 22 is connected to the pressure head body 10. A blocking member 30 is installed on the base body 21. Specifically, the base body 21 can be detachably connected to the mounting part of the welding machine. The base body 21 is detachably connected to the welding machine via bolts. The mating block 22 is located at the bottom side of the base body 21 and is centrally positioned. In this embodiment, the mating block 22 is bolted to the bottom side of the base body 21. The mating block 22 is detachably connected to the pressure head body 10 and is used to position the pressure head body 10.

[0039] In this embodiment, the mating block 22 has protrusions 221, and the pressure head body 10 has mounting grooves 110. The protrusions 221 are disposed within the mounting grooves 110, allowing the mating block 22 and the pressure head body 10 to engage. Specifically, the mating block 22 has two protrusions 221, and the number of mounting grooves 110 on the pressure head body 10 matches the number of protrusions 221, with the positions of the mounting grooves 110 corresponding to the positions of the protrusions 221. When installing the pressure head body 10, the mating block 22 and the pressure head body 10 are aligned, and then the two protrusions 221 are respectively inserted into the two mounting grooves 110 to achieve assembly. In other embodiments, the number of protrusions 221 can be increased or decreased according to actual conditions, and no specific limitation is made here.

[0040] In this embodiment, the protrusion 221 is a cylindrical structure, and the shape of the mounting groove 110 is adapted to the shape of the protrusion 221.

[0041] Furthermore, the mating block 22 is also provided with a positioning protrusion 221, which can adapt to the shape of the pressure head body 10.

[0042] In other embodiments, the mating block 22 is provided with a mounting groove 110, and the pressure head body 10 is provided with a protrusion 221. The protrusion 221 is disposed in the mounting groove 110, so that the mating block 22 and the pressure head body 10 are engaged.

[0043] Furthermore, the bottom side of the seat 21 is provided with a receiving cavity 210, and the mating block 22 is disposed in the receiving cavity 210. When the pressure head body 10 and the mating block 22 are assembled, the mounting plate 11 of the pressure head body 10 is also located in the receiving cavity 210.

[0044] It should be noted that the pressure head body 10 includes a mounting plate 11 and a positioning ring 12. The mounting plate 11 and the positioning ring 12 are connected, and a mounting groove 110 is provided in the mounting plate 11. Specifically, the bottom side of the mounting plate 11 is connected to the positioning ring 12 by welding. That is, the mounting plate 11 and the positioning ring 12 are integrally formed. The mounting plate 11 and the positioning ring 12 are in a vertical position, and the bottom of the positioning ring 12 can press down on the battery module to prevent displacement of the battery module during welding, ensuring welding accuracy.

[0045] It should also be noted that the blocking member 30 and the seat 21 are rotatably connected. In this embodiment, the blocking member 30 is a rod-shaped structure, one end of the blocking member 30 is rotatably connected to the seat 21, and the other end of the blocking member 30 is engaged with the seat 21. The blocking member 30 is used to limit the pressure head body 10 when engaged with the seat 21.

[0046] In this embodiment, the end of the blocking member 30 is provided with a slot 31, and the side of the seat 21 is provided with a block 23. The slot 31 and the block 23 cooperate to limit the blocking member 30 to the pressure head body 10.

[0047] Specifically, the blocking member 30 is disposed on the side of the base 21. One end of the blocking member 30 is rotatably connected to the base 21 via a rotating shaft, and the blocking member 30 rotates around the axis of the rotating shaft. The blocking member 30 rotates around the rotating shaft until the slot 31 at one end of the blocking member 30 engages with the locking block 23 of the base 21. At this time, the blocking member 30 is in a horizontal state and can cover the mounting plate 11 of the pressure head body 10 to prevent the mounting plate 11 and the mating block 22 from falling off.

[0048] If the pressure head body 10 needs to be replaced, rotate the blocking member 30 in the opposite direction to separate the slot 31 of the blocking member 30 from the locking block 23 of the seat body 21, and then separate the pressure head body 10 and the mating block 22.

[0049] Specifically, during the reverse rotation of the blocking member 30, it is prone to colliding with the surface of the battery module, causing the module to spark. To avoid this, the side of the base 21 of the pressure head replacement device provided in this embodiment is provided with a limiting member 40. The limiting member 40 abuts against the side of the blocking member 30 to limit the blocking member 30. The limiting member 40 is a nut. The nut is installed on the side of the base 21 and is located on the path of the blocking member 30's reverse movement. When the blocking member 30 moves in the reverse direction, its side can abut against the nut, thereby achieving the limiting effect.

[0050] In summary, this utility model embodiment provides a pressure head replacement device, which includes a pressure head body 10, a mounting base 20, and a blocking member 30. The mounting base 20 and the pressure head body 10 are detachably connected. The blocking member 30 is disposed on the mounting base 20 and is used to limit the pressure head body 10. In use, the pressure head body 10 is detachably connected to the mounting base 20, which is connected to a welding machine. The blocking member 30 is disposed on the mounting base 20 and can limit the pressure head body 10. The welding machine can move the mounting base 20 to the surface of the battery module, so that the pressure head body 10 presses against the battery module, and the welding machine performs laser welding. When the pressure head body 10 needs to be replaced, simply remove the blocking member 30 and then separate the pressure head body 10 from the mounting base 20. Replacement is quick, reducing downtime and improving production efficiency.
