Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to welding equipment for metal shells of solid-state batteries. Background Art

[0002] Solid-state batteries are a type of battery technology that, unlike the lithium-ion and lithium-ion polymer batteries commonly used today, use solid electrodes and solid electrolytes. Solid-state lithium battery technology uses a glass compound made of lithium and sodium as a conductive material, replacing the electrolyte in previous lithium batteries and significantly increasing the energy density of lithium batteries. The metal casing of a solid-state battery primarily consists of a rectangular tube, a bottom cover, and a cover plate. The bottom cover is typically first embedded within the rectangular tube and then secured to it via laser welding. After the battery pack is placed within the rectangular tube, the cover plate is removably secured to the other end of the tube to seal it, facilitating subsequent disassembly and maintenance.

[0003] A Chinese patent application with publication number CN119175491A discloses a welding device for battery metal shells, including a base, a vertical plate, a positioning mechanism, a rotating mechanism, a welding mechanism, a blowing mechanism and two fixed seats. The rotating mechanism includes a driving assembly, two rotating drums, two annular plates and multiple connecting rods. The positioning mechanism includes an electric suction cup, a pushing assembly, a rotating assembly, two telescopic assemblies and eight abutment plates. The welding mechanism includes a welding head and a moving assembly. The blowing mechanism includes a transmission assembly, a conveying assembly, two nozzles, two mounting blocks, two second strip grooves and two sliding assemblies. The eight abutment plates can be used to fix the battery bottom shell, and the electric suction cup can be used to fix the upper cover. At the same time, in conjunction with the pushing assembly, the bottom shell and the upper cover can be combined together without manual fixation. This equipment can ensure stable placement between the bottom shell and the upper cover, which is conducive to improving welding accuracy.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can separately transport the parts of the battery casing through the conveying mechanisms on both sides. When transported to the position of the clamping bin, the clamping cylinder is activated and drives the clamping plate to approach the part, and fixes it by suction through the suction cup. Then the clamping cylinders on both sides continue to drive the parts to move closer to the middle and fit together. At this time, with the cooperation of the slot and the limit block, the flip gear is always kept in a linked state with the rotating shaft. Then the driving device is started and the clamping plates on both sides are rotated synchronously through the linkage shaft, thereby cooperating with the welding equipment above to efficiently weld the parts to be welded. This design improves the stability and work efficiency of the welding equipment for solid-state battery metal casings.

[0018] 2. The present invention utilizes a lifting cylinder to freely adjust the distance between the welding equipment and the component. Furthermore, the angle and position of the welding equipment can be freely adjusted through the coordination of the first, second, and third inner cylinders. When the first toothed plate drives adjustment gear 3 to rotate, the third inner cylinder and the second active bevel gear also rotate accordingly. At this point, the second and third interlocking bevel gears cooperate to allow the welding equipment to rotate 360 ​​degrees relative to the interlocking frame and swivel base without deflection. When the second toothed plate drives adjustment gear 2 to rotate, the second inner cylinder and the first active bevel gear also rotate accordingly. The first interlocking bevel gear then causes the interlocking frame and the welding equipment to deflect to one side. As the welding equipment deflects, the second interlocking bevel gear remains stationary, allowing the third interlocking bevel gear to mesh with the welding equipment. When the third toothed plate drives adjustment gear 1 to rotate, the first inner cylinder and the swing frame also rotate accordingly. Since the first and second interlocking bevel gears remain stationary, the swing frame also rotates when it deflects the welding equipment as a whole, coordinated by the third interlocking bevel gear. In addition, in addition to starting the regulating cylinder 1, regulating cylinder 2 and regulating cylinder 3 separately, the coordination of different regulating cylinders and different rotational speeds can achieve quite complex movements of the welding equipment. This design improves the practicality and freedom of the welding equipment for the metal shell of the solid-state battery. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The present invention provides a welding device for a solid-state battery metal shell by improving Figures 1-11As shown, it includes an operating frame 1, two sets of symmetrical conveying chambers 2 are opened in the middle of the operating frame 1, and a conveying mechanism 3 for conveying battery components is set in the conveying chamber 2; a welding bin 6 is opened in the middle of the operating frame 1, and clamping bins 7 located on both sides of the welding bin 6 are set on both sides of the operating frame 1; a clamping cylinder 8 is installed on the inner wall of the clamping bin 7, and a rotating shaft 9 is movably installed on the output end of the clamping cylinder 8, and a clamping plate 12 is fixedly provided on the outer side of the rotating shaft 9, and multiple sets of air pumps 13 are installed on the inner wall of the clamping plate 12, and a suction cup 14 is provided at the output end of the air pump 13; an arc plate 25 is also fixedly provided on the top of the welding bin 6, and a moving seat 27 is movably installed on the arc plate 25, and the moving seat 27 A lifting cylinder 28 is installed at the bottom, and an outer cylinder 29 is fixedly installed at the output end of the lifting cylinder 28; a first inner cylinder 30 is movably installed inside the outer cylinder 29, and a symmetrical swing frame 32 is provided at the bottom of the first inner cylinder 30, one group of which is movably installed with a first linkage bevel gear 33 on the inner side, and a linkage frame 34 is fixedly provided on the first linkage bevel gear 33, and a welding device 36 is movably installed at the end of the linkage frame 34; a second inner cylinder 40 is movably installed inside the first inner cylinder 30, and a third inner cylinder 44 is movably installed inside the second inner cylinder 40; the first inner cylinder 30, the second inner cylinder 40 and the third inner cylinder 44 cooperate with each other to freely adjust the angle and position of the welding device 36.

[0035] In this embodiment, the welding equipment for the metal shell of a solid-state battery is mainly divided into three parts: an operating frame 1, a clamping plate 12, and a welding device 36 structure. When the equipment is in use, the parts are first placed on the conveying mechanism 3 on both sides at intervals. When the parts are conveyed to the side of the clamping plate 12, the clamping cylinder 8 and the air pump 13 are started. When the parts are fixed to the clamping plate 12 by the suction cup 14, the parts on both sides move closer to the middle and fit together under the action of the clamping cylinder 8. Finally, the driving device 23 is started to drive the parts on both sides to rotate synchronously and start the welding device 36. During the welding operation, the distance between the welding device 36 and the parts can be freely adjusted by the lifting cylinder 28, and the angle and position of the welding device 36 can be quickly adjusted and responded by adjusting the cylinder 1 48, the adjusting cylinder 2 49 and the adjusting cylinder 3 50 and their different combinations.

[0036] See attached Figure 4 -Attached Figure 6 The output end of the clamping cylinder 8 is provided with a mounting seat 10, and the rotating shaft 9 is provided with a limiting groove 11 that cooperates with the mounting seat 10.

[0037] In this embodiment: when the clamping cylinder 8 drives the parts on the conveying mechanism 3 to move closer to the middle, in order to ensure that the rotating shaft 9 can rotate freely relative to the clamping cylinder 8, thereby performing all-round welding on the fitting parts of the parts, a mounting seat 10 and a limiting groove 11 structure that cooperate with each other are designed.

[0038] See attached Figure 6 -Attached Figure 7 , multiple groups of card slots 15 are provided on the outer wall of the rotating shaft 9, and a support frame 16 is fixedly provided on the inner wall of the clamping bin 7, and a hole slot 17 is provided on the support frame 16 for the rotating shaft 9 to pass through; a flip gear 18 is movably installed on the outer wall of the support frame 16, and multiple groups of limit blocks 19 that cooperate with the card slots 15 are provided in the middle of the flip gear 18.

[0039] In this embodiment: since the flip gear 18 is fixed in the horizontal direction, when the clamping cylinder 8 drives the rotating shaft 9 to move inward, in order to ensure that the flip gear 18 and the rotating shaft 9 always maintain a linked meshing state, a mutually cooperating card slot 15 and limit block 19 structure is designed.

[0040] See attached Figure 2 -Attached Figure 3 A driving device 23 is installed inside one group of the clamping bins 7, and a driving gear 24 engaged with the flip gear 18 is installed at the output end of the driving device 23.

[0041] In this embodiment, a driving device 23 is provided to drive the rotating shaft 9 and the clamping plate 12 to rotate and thereby perform welding operations on the battery housing components.

[0042] See attached Figure 2 -Attached Figure 3 A linkage shaft 21 located between the clamping bins 7 is also movably installed in the middle of the conveying chamber 2. A convex ring 20 is provided on the outer wall of the flip gear 18. A belt 22 is connected to the convex ring 20. The flip gear 18 is connected to the linkage shaft 21 through the belt 22.

[0043] In this embodiment, when the driving device 23 drives one set of rotating shafts 9 to rotate, a linkage shaft 21 structure is designed to ensure that the clamping plates 12 on both sides rotate synchronously and avoid relative sliding.

[0044] See attached Figure 10 -Attached Figure 11 A rotating inner cavity 1 39 is opened inside the first inner cylinder 30 for the second inner cylinder 40 to rotate, and a rotating inner cavity 2 43 is opened inside the second inner cylinder 40 for the third inner cylinder 44 to rotate.

[0045] In this embodiment, a first rotating inner chamber 39 is provided to mount the second inner cylinder 40 inside the first inner cylinder 30 and ensure its stability during rotation. A second rotating inner chamber 43 is provided to mount the third inner cylinder 44 inside the second inner cylinder 40 and ensure its stability during rotation.

[0046] See attached Figure 8 -Attached Figure 11The end of the linkage frame 34 is also provided with a rotating seat 35 that cooperates with the welding equipment 36. The top of the welding equipment 36 is provided with a third linkage bevel gear 37. The inner side of another set of swing frames 32 is movably installed with a second linkage bevel gear 38 that meshes with the third linkage bevel gear 37; an adjusting gear 1 31 is installed on the top outer wall of the first inner cylinder 30, and a first active bevel gear 42 that meshes with the first linkage bevel gear 33 is provided at the bottom of the second inner cylinder 40; an adjusting gear 2 41 located above the adjusting gear 1 31 is installed on the top outer wall of the second inner cylinder 40; a second active bevel gear 46 that meshes with the second linkage bevel gear 38 is provided at the bottom of the third inner cylinder 44, and an adjusting gear 3 45 located above the adjusting gear 2 41 is installed on the top outer wall of the third inner cylinder 44.

[0047] In this embodiment, when the first toothed plate 51 drives the adjustment gear 3 45 to rotate, the third inner cylinder 44 and the second driving bevel gear 46 also rotate accordingly. At this point, with the cooperation of the second linkage bevel gear 38 and the third linkage bevel gear 37, the welding device 36 rotates 360 degrees relative to the linkage frame 34 and the rotating base 35 without deflection. When the second toothed plate 52 drives the adjustment gear 2 41 to rotate, the second inner cylinder 40 and the first driving bevel gear 42 also rotate accordingly. At this point, the first linkage bevel gear 33 causes the linkage frame 34 and the welding device 36 to deflect to one side. As the welding device 36 deflects, because the second linkage bevel gear 38 remains stationary, the third linkage bevel gear 37 engages, causing the welding device 36 to rotate accordingly. When the third toothed plate 53 drives the adjustment gear 1 31 to rotate, the first inner cylinder 30 and the swing frame 32 also rotate accordingly. Since the first active bevel gear 42 and the second active bevel gear 46 remain stationary, when the swing frame 32 drives the welding device 36 to deflect as a whole, the welding device 36 will also rotate relative to the rotating base 35 with the cooperation of the third linkage bevel gear 37 .

[0048] See attached Figure 8 -Attached Figure 9 The output end of the lifting cylinder 28 is also fixedly provided with a mounting bracket 47, and the outer wall of the mounting bracket 47 is installed with an adjusting cylinder 1 48, an adjusting cylinder 2 49 and an adjusting cylinder 3 50. The output end of the adjusting cylinder 1 48 is installed with a first gear plate 51 engaged with the adjusting gear 3 45, the output end of the adjusting cylinder 2 49 is installed with a second gear plate 52 engaged with the adjusting gear 2 41, and the output end of the adjusting cylinder 3 50 is installed with a third gear plate 53 engaged with the adjusting gear 1 31.

[0049] In this embodiment, in addition to independently activating the first, second, and third control cylinders 48, 49, and 50, the coordination of the different control cylinders and the different rotational speeds can achieve quite complex movements of the welding device 36. For example, when the first and second control cylinders 48, 49 are activated simultaneously, the welding device 36 can be independently deflected or simultaneously rotated rapidly.

[0050] See attached Figure 1 and attached Figure 3 A traveling gear ring 26 is installed on the inner wall of the arc plate 25, a control panel 4 is provided on the outer wall of the operating frame 1, and symmetrical observation windows 5 are also provided on both sides of the operating frame 1.

[0051] In this embodiment: in order to control the operation of the equipment, a control panel 4 structure is designed. In order to facilitate the observation of the internal parts conveying and welding conditions, an observation window 5 structure is designed.

[0052] The working principle of the present invention is as follows: When the device is in use, the parts are first placed on the conveying mechanisms 3 on both sides at intervals. When the parts are conveyed to the side of the clamping plate 12, the clamping cylinder 8 and the air pump 13 are activated. When the parts are fixed to the clamping plate 12 by the suction cup 14, the parts on both sides are moved toward the center and fit together under the action of the clamping cylinder 8. Finally, the driving device 23 is activated to drive the parts on both sides to rotate synchronously and start the welding device 36. During the welding operation, the distance between the welding device 36 and the parts can be freely adjusted by the lifting cylinder 28, and the angle and position of the welding device 36 can be quickly adjusted and responded by adjusting the cylinder 1 48, the adjusting cylinder 2 49 and the adjusting cylinder 3 50 and their different combinations.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
