Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a laser welding device and method for solid-state battery modules. Background Technology

[0002] Solid-state batteries use solid electrolytes instead of liquid electrolytes, and the interfacial bonding strength directly affects the battery's cycle life and safety. Laser welding, through high-energy-density, non-contact processing, can achieve precise welding of solid electrolytes and electrodes in a vacuum or inert gas environment, avoiding material contamination or thermal damage caused by traditional welding. Solid-state battery modules need to connect dissimilar metals such as aluminum, copper, and nickel. Traditional welding is prone to cracking or incomplete welding due to differences in melting points. Laser welding, through the deep penetration welding effect, forms small holes on the material surface, allowing light energy to directly reach the bottom of the hole, achieving spatter-free fusion of dissimilar metals. However, existing laser welding equipment for solid-state battery modules cannot quickly adjust the pressing position during welding, which reduces the applicability of welding different batteries.

[0003] The shortcomings of existing laser welding equipment for solid-state battery modules are:

This invention can realize the automation of battery tab welding, improve the welding quality of tab welding, and thus improve the pass rate of tab welding, and is simple to operate and convenient to use." However, existing solid-state battery module laser welding equipment cannot stably fix the solid-state battery module when transporting it, which reduces the welding quality.

However, existing solid-state battery module laser welding equipment cannot detect welding quality in time, reducing production efficiency.

[0007] 4. Patent document CN220050420U discloses a laser welding equipment for battery modules.

[0014] Preferably, a welding detection component is installed on the outer wall of the laser welding head, and a lubrication component is installed on the inner wall of the first transverse moving rod.

[0015] Preferably, the welding inspection component includes a camera and a processing module.

[0017] Preferably, the lubrication assembly includes a fourth box, a first slide rail, a first pulley, a connecting rod, a discharge pipe, a fifth box, and a sealing head. The fourth box is located on the inner wall of the first transverse moving rod. The first slide rail is located on the inner wall of the first transverse moving rod. The first pulley is installed on the inner wall of the first slide rail.

[0018] Preferably, the sealing head seals the discharge pipe, the sixth slide cylinder moves via the sixth slide rod, and the discharge pipe is located above the first pulley.

[0019] Preferably, the method of using the welding device includes the following steps:

[0020] Step S1: Pulling the lever moves the first spring. The movement of the first spring causes the lever to move the first clamp out of the first slot. At this time, the first motor rotates, which drives the winding wheel to rotate. The rotation of the winding wheel drives the pull rope to move. The movement of the pull rope drives the first rod to move. The movement of the first rod drives the pressure head to move. The movement of the pressure head adjusts its position, thus realizing the function of quickly adjusting the pressure plate position during the welding of solid-state battery module laser welding equipment to improve the applicability of welding different batteries.

[0021] Step S2: The function of the second support rod is to provide support for the third sleeve. The movement of the pneumatic head drives the fourth rod to move, the movement of the fourth rod drives the third spring to move, the movement of the third spring causes the fourth rod to drive the second clamp to move, and the movement of the second clamp causes the second clamp block to fix the solid-state battery module. At this time, the electromagnetic block is activated to generate magnetic force to fix the second clamp, thus realizing the function of stable fixing and improving welding quality when the solid-state battery module laser welding equipment is transporting the solid-state battery module.

[0022] Step S3: When the processing module detects a qualified state, it controls the conveyor belt to start, and the conveyor belt starts to perform the next welding. After the next welding, the camera continuously monitors the real-time welding status of the solid-state battery module until the processing module detects a qualified state or a state without raw materials. When the processing module detects a qualified state, it controls the conveyor belt to stop, and the conveyor belt stops to perform maintenance. After maintenance, the camera continues to monitor the real-time welding status of the solid-state battery module until the processing module detects a qualified state or a state without raw materials. When the processing module detects a state without raw materials, it controls the conveyor belt to stop, and the conveyor belt stops to perform maintenance. After maintenance, the camera continues to monitor the real-time welding status of the solid-state battery module until the processing module detects a qualified state or a state without raw materials. This realizes the function of timely detection and improved production efficiency of the solid-state battery module laser welding equipment.

[0023] Step S4: The movement of the first horizontal moving rod drives the connecting rod to move, which in turn drives the first pulley to move. At this time, the rotation of the third motor drives the threaded rod to rotate, which in turn drives the threaded sleeve to move. The movement of the threaded sleeve drives the fifth bracket to move, which in turn drives the sixth slide cylinder to move. The movement of the sixth slide cylinder causes the fifth bracket to drive the sealing head to move, which in turn opens the discharge pipe. At this time, the lubricating oil in the fourth box is discharged through the discharge pipe to the surface of the sixth slide cylinder to lubricate it, thus realizing the function of automatic lubrication of the first horizontal moving rod to improve the movement stability of the solid-state battery module laser welding equipment.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention utilizes a pull rod to move a first spring, which in turn causes the pull rod to move a first clamp out of a first slot. At this time, a first motor rotates, which in turn rotates a winding wheel. The rotation of the winding wheel moves a pull rope, which in turn moves a first rod, which in turn moves a pressure head. The pressure head is then moved to adjust its position, thus enabling the laser welding equipment for solid-state battery modules to quickly adjust the pressure plate position and improve the applicability of welding different batteries.

[0026] 2. The present invention uses a second support rod to provide support for a third sleeve. The movement of the pneumatic head drives the movement of a fourth rod, which in turn drives the movement of a third spring. The movement of the third spring causes the fourth rod to drive the movement of a second clamp, which in turn fixes the solid-state battery module in place. At this time, the electromagnetic block is activated to generate magnetic force to fix the second clamp, thus realizing the function of stable fixing and improved welding quality of the solid-state battery module laser welding equipment during the transport of solid-state battery modules.

[0027] 3. This invention, through the installation of a processing module, detects a qualified state and controls the conveyor belt to start, allowing for the next welding operation. After the next welding operation, the camera continuously monitors the real-time welding status of the solid-state battery module until the processing module detects a qualified state or a lack of raw materials. If the processing module detects a qualified state, it controls the conveyor belt to stop, allowing for maintenance. After maintenance, the camera continues to monitor the real-time welding status of the solid-state battery module until the processing module detects a qualified state or a lack of raw materials. If the processing module detects a lack of raw materials, it controls the conveyor belt to stop, allowing for maintenance. After maintenance, the camera continues to monitor the real-time welding status of the solid-state battery module until the processing module detects a qualified state or a lack of raw materials. This invention achieves the function of timely detection and improved production efficiency in the laser welding equipment for solid-state battery modules.

[0028] 4. This invention utilizes a first transverse moving rod to move a connecting rod, which in turn moves a first pulley. Simultaneously, a third motor rotates, causing a threaded rod to rotate. This rotation of the threaded rod then moves a threaded sleeve, which in turn moves a fifth support bracket. The fifth support bracket then moves a sixth slide cylinder, which in turn moves the fifth support bracket, causing the sealing head to move. This opening of the discharge pipe allows lubricating oil from the fourth tank to be discharged through the discharge pipe onto the surface of the sixth slide cylinder, thus achieving automatic lubrication of the first transverse moving rod and improving the stability of the solid-state battery module laser welding equipment.

[0046] The method of using this welding device includes the following steps:

[0047] Step S1: Pulling the lever 18 moves the first spring 19. The movement of the first spring 19 causes the lever 18 to move the first clamp 50 out of the first slot 13. At this time, the first motor 14 rotates, driving the winding wheel 15 to rotate. The rotation of the winding wheel 15 drives the pull rope 16 to move. The movement of the pull rope 16 drives the first rod 10 to move. The movement of the first rod 10 drives the pressure head 11 to move. The movement of the pressure head 11 adjusts its position, realizing the function of quickly adjusting the pressure plate position during the welding of solid-state battery module laser welding equipment to improve the applicability of welding different batteries.

[0048] Step S2: The function of the second support rod 23 is to provide support for the third sleeve 24. The movement of the pneumatic head 22 drives the fourth rod 25 to move, which in turn drives the third spring 26 to move. The movement of the third spring 26 causes the fourth rod 25 to drive the second clamp 31 to move. The movement of the second clamp 31 causes the second clamp block 28 to fix the solid-state battery module. At this time, the electromagnetic block 30 is activated to generate magnetic force to fix the second clamp 31, thus realizing the function of stable fixing and improved welding quality of the solid-state battery module laser welding equipment when transporting solid-state battery modules.

[0049] Step S3: When the processing module detects a qualified state, it controls the conveyor belt 20 to start, and the conveyor belt 20 starts to perform the next welding. After the next welding, the camera 49 continuously monitors the real-time welding status photos of the solid-state battery module until the processing module detects a qualified state or a state without raw materials. When the processing module detects a qualified state, it controls the conveyor belt 20 to stop, and the conveyor belt 20 stops to perform maintenance. After maintenance, the camera 49 continues to monitor the real-time welding status photos of the solid-state battery module until the processing module detects a qualified state or a state without raw materials. When the processing module detects a state without raw materials, it controls the conveyor belt 20 to stop, and the conveyor belt 20 stops to perform maintenance. After maintenance, the camera 49 continues to monitor the real-time welding status photos of the solid-state battery module until the processing module detects a qualified state or a state without qualified materials. This realizes the function of timely detection and improved production efficiency of the solid-state battery module laser welding equipment.

[0050] Step S4: The movement of the first horizontal moving rod 5 drives the connecting rod 36 to move, which in turn drives the first pulley 35 to move. At this time, the third motor 39 rotates, driving the threaded rod 40 to rotate. The rotation of the threaded rod 40 drives the threaded sleeve 41 to move, which in turn drives the fifth bracket 43 to move. The movement of the fifth bracket 43 drives the sixth slide cylinder 45 to move, which in turn causes the fifth bracket 43 to drive the sealing head 46 to move. The movement of the sealing head 46 causes the discharge pipe 37 to open. At this time, the lubricating oil in the fourth box 33 is discharged through the discharge pipe 37 to the surface of the sixth slide cylinder 45 to lubricate it. This realizes the function of automatic lubrication of the first horizontal moving rod 5 to improve the movement stability of the solid-state battery module laser welding equipment.

[0051] Working principle: Pulling the pull rod 18 moves the first spring 19, which in turn moves the pull rod 18, causing the first clamp 50 to move out of the first slot 13. At this time, the first motor 14 rotates, driving the winding wheel 15 to rotate. The rotation of the winding wheel 15 drives the pull rope 16 to move, which in turn moves the first rod 10. The movement of the first rod 10 drives the pressure head 11 to move, thus adjusting its position. This achieves the function of quickly adjusting the pressure plate position during the laser welding of solid-state battery modules, improving the applicability of welding different batteries. The function of the second support rod 23 is to provide support for the third sleeve 24. The movement of the pneumatic head 22 drives the fourth rod 25 to move. The movement of rod 5 drives spring 26 to move, which in turn causes rod 25 to move clamp 31. Clamp 31 then moves clamp block 28 to fix the solid-state battery module. At this point, electromagnetic block 30 activates, generating magnetic force to fix clamp 31, thus achieving stable fixing and improved welding quality during the transport of the solid-state battery module laser welding equipment. When the processing module detects a qualified state, it controls conveyor belt 20 to start, initiating the next welding operation. After the next welding, camera 49 continuously monitors the real-time welding status of the solid-state battery module until the processing module detects an unqualified state or a lack of raw materials. When the processing module detects a non-conforming condition, it controls the conveyor belt 20 to stop operating for maintenance. After maintenance, the camera 49 continuously monitors the real-time welding status of the solid-state battery module until the processing module detects a conforming condition or a material shortage. This achieves the function of timely detection and improved production efficiency of the solid-state battery module laser welding equipment. (The first horizontal moving rod...) The movement of rod 5 drives the connecting rod 36 to move, which in turn drives the first pulley 35 to move. At this time, the third motor 39 rotates, which drives the threaded rod 40 to rotate. The rotation of the threaded rod 40 drives the threaded sleeve 41 to move, which in turn drives the fifth bracket 43 to move. The movement of the fifth bracket 43 drives the sixth slide cylinder 45 to move, which in turn causes the fifth bracket 43 to drive the sealing head 46 to move. The movement of the sealing head 46 causes the discharge pipe 37 to open. At this time, the lubricating oil in the fourth box 33 is discharged through the discharge pipe 37 to the surface of the sixth slide cylinder 45 to lubricate it. This realizes the function of automatic lubrication of the first horizontal moving rod 5 to improve the movement stability of the solid-state battery module laser welding equipment.
