[0020] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides a welding auxiliary tool for a new energy blade battery housing, such as Figure 1-14 As shown, it includes: a tooling table 10, a positioning mechanism 20, a first locking assembly 30 and a rotating assembly 40, and the tooling table 10 is used to support the battery housing 50 to be welded; The rotating assembly 40 includes a first frame 41 and a second frame 42 that are arranged opposite to each other, the tooling table 10 is located between the first frame 41 and the second frame 42 brackets, a first rotating frame 43 is fixedly installed on one end of the tooling table 10, and a second rotating frame 44 corresponding to the first rotating frame 43 is fixedly installed on the other end of the tooling table 10; a first rotating shaft 45 rotatably connected to the first frame 41 is installed on one side of the first rotating frame 43, and a second rotating shaft 46 rotatably connected to the second frame 42 is installed on one side of the second rotating frame 44; a rotating motor 47 for driving the tooling table 10 to rotate is also installed on the first frame 41; in this embodiment, the rotating motor 47 provides driving power, so that the first rotating shaft 45 drives the first rotating frame 43 to move, and since the first rotating frame 43 is fixedly connected to the tooling table 10, it drives the tooling table 10 to rotate, and makes the second rotating frame 44 and the second rotating shaft 46 rotate synchronously; The positioning mechanism 20 is installed on the tooling table 10 and is used to position the battery housing 50 to be welded. The first locking assembly 30 is installed on the first frame 41. The first locking assembly 30 is used to lock and limit the tooling table 10. After the first locking assembly 30 unlocks the tooling table 10 , the rotating assembly 40 drives the tooling table 10 to rotate to a preset angle according to the welding position of the battery shell 50 to be welded, so that the battery shell 50 to be welded can be welded smoothly.

[0024] It should be noted that the welding auxiliary tooling for a new energy blade battery shell provided by the present invention can position the battery shell 50 to be welded on the tooling table 10 through the positioning function of the positioning mechanism 20, thereby ensuring the stability of the battery shell during the welding process and avoiding welding defects caused by offset; the tooling table 10 is driven to rotate by the rotating motor 47, which drives the battery shell 50 to be welded to rotate, so that the tooling table 10 can rotate flexibly to meet the needs of different welding positions, reduce the workpiece adjustment time, and improve the welding efficiency. The first locking assembly 30 provides a reliable limiting function to ensure that the tooling table 10 and the battery shell 50 to be welded will not move accidentally during the welding process. Therefore, the welding auxiliary tooling for a new energy blade battery shell provided by the present invention simplifies the operation process, reduces the difficulty of operation, and improves the welding efficiency by integrating the rotation, positioning and locking functions.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the battery housing 50 to be welded includes a battery bottom plate 51, a battery side plate 52, a battery separator plate 53 and a battery corner plate 54 which are sequentially spliced; two battery side plates 52 are respectively on opposite sides of the battery bottom plate 51; a plurality of battery separator plates 53 are distributed on the battery bottom plate 51, and four battery corner plates 54 are distributed around the battery bottom plate 51; The positioning mechanism 20 includes a first positioning assembly 21, a second positioning assembly 22 and a third positioning assembly 23 respectively mounted on the tooling table 10, two first positioning assemblies 21 are arranged opposite to each other, two second positioning assemblies 22 are arranged opposite to each other, and four third positioning assemblies 23 are distributed at the four corners of the battery housing 50 to be welded; The first positioning assembly 21 is used to position the battery side plate 52 , the second positioning assembly 22 is used to position the battery partition plate 53 , and the third positioning assembly 23 is used to position the battery corner plate 54 .

[0026] In the specific implementation process, the battery housing 50 to be welded is positioned and installed using the following method: Place the battery bottom plate 51, the battery side plate 52, the battery separator plate 53 and the battery corner plate 54 which are sequentially assembled on the workbench 10; After positioning one group of two diagonally arranged battery corner plates 54 respectively by two of the third positioning assemblies 23, positioning another group of two diagonally arranged battery corner plates 54 respectively by the other two third positioning assemblies 23; in this embodiment, the battery corner plates 54 are first positioned by the third positioning assemblies 23 to ensure that the bottom position of the battery housing 50 to be welded is fixed, which can facilitate the subsequent positioning of the battery separator 53 and the battery side plate 52; The battery separator 53 is positioned respectively by two oppositely arranged second positioning components 22; in this embodiment, the battery separator 53 is positioned and installed by the second positioning component 22, which can prevent the battery side plate 52 from affecting the positioning of the battery separator 53 due to the first positioning; The two battery side plates 52 are positioned respectively by two oppositely disposed first positioning components 21. In this embodiment, the battery angle plate 54, the battery separator plate 53 and the battery side plate 52 are positioned in sequence, so that the battery housing 50 to be welded can be accurately positioned to ensure the subsequent welding quality.

[0027] It should be noted that the first positioning assembly 21, the second positioning assembly 22 and the third positioning assembly 23 all play a positioning role, realizing the positioning of the battery side plate 52, the battery separator 53 and the battery corner plate 54; they can minimize the installation error, improve the overall assembly accuracy, and ensure that the battery shell is accurately welded. The use of the positioning assembly ensures that the battery shell will not move during welding, thereby ensuring the uniformity and consistency of welding.

[0028] like Fig.10 and Fig.11 As shown, a plurality of magnetic seats 60 distributed in a matrix are installed in the workbench 10, and a through hole 11 corresponding to the magnetic seat 60 is opened on the workbench 10. In the specific implementation process, the number of magnetic seats 60 is set to six. Through the magnetic attraction of the magnetic seat 60, the battery bottom plate 51 is magnetically fixed to prevent the battery bottom plate 51 from moving, thereby ensuring smooth welding of the battery shell. Among them, an electromagnet is provided in the magnetic seat 60. When the current disappears, the magnetism of the magnetic seat 60 disappears, and the battery bottom plate can be removed smoothly. Exemplarily, a positioning frame 80 is installed on the side wall of the workbench 10, and the positioning frame 80 is used to install and position the battery side plate 52. A positioning platform 90 is installed on the table top of the workbench 10, and a plurality of positioning rods 901 are installed on the positioning platform 90. The positioning platform 90 and the positioning rods 901 are used to position and install other inner shells of the battery shell; a positioning protrusion 100 arranged adjacent to the second positioning component 22 is installed on the table top of the workbench 10, and a positioning notch 101 for positioning the battery bottom plate 51 is installed on the positioning protrusion 100.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, the first positioning assembly 21 includes a first mounting seat 211, a second mounting seat 212 and a first positioning cylinder 213. The two second mounting seats 212 are fixed in parallel on the side wall of the workbench 10, and a first rotating shaft 214 is rotatably connected between the two second mounting seats 212. The opposite ends of the first rotating shaft 214 are sleeved with first positioning plates 215. The first positioning plates 215 are used to position the battery side plate 52. The first mounting seat 211 is fixedly connected to the workbench 10, one end of the first positioning cylinder 213 is hinged to the first mounting seat 211, and the telescopic rod of the first positioning cylinder 213 is connected to the first positioning plate 215 through the first connecting rod 216. In this embodiment, the first connecting rod 216 drives the first positioning plate 215 to swing through the driving action of the first positioning cylinder 213, thereby making the first positioning plate 215 move away from or close to the battery side plate 52.

[0030] It should be noted that by fitting the first positioning plate 215 with the battery side plate 52, high-precision positioning of the battery side plate 52 is achieved, ensuring that the welding angles and positions between the side plate and the battery bottom plate 51 and other components meet the design requirements. The mechanical structure of the first positioning assembly 21 is relatively simple, and the cylinder, connecting rod and rotating shaft are easy to maintain, reducing the maintenance cost and downtime of the equipment. After the battery side plate 52 is accurately positioned, it remains in a fixed position during the welding process and will not be offset by external forces or welding thermal stress, ensuring the uniformity of the weld and the welding strength. High-precision positioning improves the first-time pass rate of welding and reduces rework and material waste.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, a first connecting plate 217 is connected between the two first positioning plates 215, a first pressing block 218 is installed on the first connecting plate 217, and a first positioning block 219 for positioning and crimping with the first pressing block 218 is fixedly installed on the workbench 10. In the specific implementation process, the first connecting plate 217 and the first pressing block 218 are fastened and connected by screws. Through the positioning and crimping of the first pressing block 218 and the first positioning block 219, the moving stroke of the first positioning plate 215 is limited, which can prevent the first positioning plate 215 from further squeezing the battery side plate 52. The heights of the two first positioning plates 215 can be the same or different; they can be adapted and installed according to the shape of the battery shell. Through two first positioning plates 215 of different heights, irregular side panels can be positioned to improve the positioning adaptability of the first positioning assembly 21.

[0032] like Figure 1 , Figure 7 and Figure 8 As shown, the second positioning assembly 22 includes a first mounting platform 221, a second mounting platform 222 and a second positioning cylinder 223, and the first mounting platform 221 is fixedly connected to the bottom of the tooling platform 10; The two second mounting platforms 222 are fixed parallel to the table surface of the workbench 10, and a second rotating shaft 224 is rotatably connected between the two second mounting platforms 222, and second rotating plates 225 are sleeved at opposite ends of the second rotating shaft 224; a second positioning plate 226 is installed on the second rotating plate 225; the second positioning plate 226 is used to position the battery separator 53; and a positioning inclined surface for positioning is provided on the second positioning plate 226; One end of the second positioning cylinder 223 is hinged to the first mounting platform 221, and the telescopic rod of the second positioning cylinder 223 is connected to the second rotating plate 225 through the second connecting rod 227. In the specific implementation process, the second rotating plate 225 is fixedly connected with a mounting bar 2252, and three third positioning plates 233 are installed on the mounting bar 2252 at intervals.

[0033] It should be noted that, through the driving action of the second positioning cylinder 223, the second connecting rod 227 drives the second rotating plate 225 to swing, and then the second rotating plate 225 drives the second positioning plate 226 to swing, and then the second positioning plate 226 is moved away from or close to the battery separator 53. By providing multiple third positioning plates 233, the number of battery separators 53 can be increased.

[0034] like Figure 1 , Figure 7 and Figure 8 As shown, a second connecting plate 2251 is installed between the two second rotating plates 225, and a second pressing block 228 is fixedly installed on the second connecting plate 2251; A second positioning block 229 is installed on the table of the workbench 10. A slot 2291 is provided through the second positioning block 229. The second pressing block 228 is plugged into the slot 2291. In the specific implementation process, the second connecting plate 2251 is welded and fixed to the second rotating plate 225, and the second pressing block 228 is fastened to the second rotating plate 225 by screws; when the third positioning plate 233 positions the battery separator, the second pressing block 228 is separated from the slot 2291; when the battery separator does not need to be positioned, the second pressing block 228 is reinserted into the slot 2291 through the driving action of the second positioning cylinder 223 to limit the installation of the second rotating plate 225.

[0035] like Figure 1 , Figure 2 and Fig. 9As shown, the third positioning assembly 23 includes a third positioning seat 231 fixedly mounted on the workbench 10, and a third positioning cylinder 232 and a third positioning plate 233 are respectively hinged on the third positioning seat 231, and the telescopic rod of the third positioning cylinder 232 is hinged to the third positioning plate 233; the third positioning plate 233 is used to position the battery corner plate 54. In the specific implementation process, the third positioning plate 233 is set in an L shape, and a positioning portion 2331 is provided at one end of the third positioning plate 233.

[0036] It should be noted that the third positioning plate 233 is driven to move by the driving action of the third positioning cylinder 232 so that the positioning portion 2331 is close to or away from the battery angle plate 54; when the positioning portion 2331 contacts the battery angle plate 54, the battery angle plate 54 is quickly positioned.

[0037] like Figure 1 and Figure 3 As shown, the first locking assembly 30 includes a first locking rod 31 and a first locking cylinder 32 fixedly mounted on a first frame 41; a first slide rail 33 is mounted on the first frame 41, a first slider 34 is slidably connected to the first slide rail 33, a first slide plate 35 is connected to the first slider 34, and the first slide plate 35 is respectively connected to the first locking rod 31 and the telescopic rod of the first locking cylinder 32; a first locking groove 12 plugged with the first locking rod 31 is provided on the workbench 10. In this embodiment, the first slide plate 35 is respectively welded and fixed to the first locking rod 31 and the telescopic rod of the first locking cylinder 32.

[0038] It should be noted that the first locking block is driven to move by the first locking cylinder 32, so that the first slider 34 moves on the first slide rail 33, and at the same time drives the first locking rod 31 to move; when the first locking rod 31 is inserted into the first locking groove 12, the workbench 10 is locked to ensure that the workbench 10 and the battery shell 50 to be welded will not move accidentally during the welding process, thereby improving the welding quality; at the same time, it can also prevent the rotating assembly 40 from accidentally driving the workbench 10 to rotate.

[0039] like Figure 1 and Fig.14 As shown, it also includes a second locking assembly 70, which is installed on the second frame 42; wherein the first locking assembly 30 and the second locking assembly 70 are symmetrically distributed, or the first locking assembly 30 and the second locking assembly 70 are diagonally distributed.

It should be noted that the second locking block is driven to move by the second locking cylinder 72, so that the second slider 74 moves on the second slide rail 73, and at the same time drives the second locking rod 71 to move; when the second locking rod 71 is inserted into the second locking groove 13, the tooling table 10 is locked to ensure that the tooling table 10 and the battery housing 50 to be welded will not move accidentally during the welding process, thereby improving the welding quality; at the same time, it can also prevent the rotating assembly 40 from accidentally driving the tooling table 10 to rotate.

[0041] The present invention provides a welding auxiliary tool for a new energy blade battery housing, which uses the following control method for auxiliary welding: The battery housing 50 to be welded is positioned and installed on the tooling table 10 by the positioning mechanism 20, and the first locking assembly 30 locks the tooling table 10; in the embodiment, the first positioning assembly 21 is used to position the battery side plate 52, the second positioning assembly 22 is used to position the battery separator 53, the third positioning assembly 23 is used to position the battery corner plate 54, and the magnetic seat 60 is used to position the battery bottom plate 51; Scan and identify the battery shell 50 to be welded by an industrial vision system or laser scanning equipment to determine the weld position and distribution of the battery shell 50 to be welded; According to the position and distribution of the weld seams of the battery shell 50 to be welded, and in combination with the welding sequence, the rotation angle and path required by the tooling table 10 are obtained; in this embodiment, the rotary motor 47 can rotate forward and reverse to control the rotation direction of the tooling table 10; illustratively, the welding sequence of the battery shell 50 to be welded is to first weld the weld seam between the battery separator 53 and the battery bottom plate 51, then weld the weld seam between the battery separator 53 and the battery side plate 52, and finally weld the weld seam between the battery angle plate 54 and the battery bottom plate 51; The tooling table 10 is dynamically unlocked by the first locking assembly 30, and the rotating assembly 40 drives the tooling table 10 to move to the corresponding welding position according to the preset rotation angle and path; in this embodiment, the battery housing 50 to be welded is welded manually or by an intelligent robot; an angle sensor (not shown) for detecting the rotation angle of the tooling table 10 is installed on the first rotating shaft 45 or the second rotating shaft 46; After the battery shell 50 to be welded on the workbench 10 is welded, the rotating assembly 40 drives the workbench 10 to move to the initial position, and the first locking assembly 30 relocks the workbench 10. In this embodiment, a rotation memory module (not shown) can also be provided in the rotating assembly 40, and the rotation memory module is used to record the rotation process of the workbench 10, so as to realize the rapid reset of the workbench 10; when it is necessary to weld another identical battery shell 50 to be welded, the control method can be quickly applied, some processing steps are omitted, the speed of auxiliary welding is accelerated, and the welding efficiency is improved.

[0042] Exemplarily, the welding auxiliary tooling for the new energy blade battery housing provided by the present invention can also use the following control method for auxiliary welding: The battery bottom plate 51, the battery side plate 52, the battery separator plate 53 and the battery corner plate 54 which are spliced ​​in sequence are placed on the workbench 10, and two of the third positioning components 23 are used to position a group of two diagonally arranged battery corner plates 54 respectively, and the magnetic suction seat 60 magnetically positions the battery bottom plate 51 to lock the initial welding reference point; the joints of the positioned battery bottom plate 51 and the battery side plate 52 are welded to form a preliminary stable battery housing frame; The remaining two battery angle plates 54 are positioned by using the other two third positioning components 23, and the joints between the battery angle plates 54 and the battery bottom plate 51 are welded one by one; The battery separator 53 is positioned by the second positioning component 22 to ensure its verticality and position accuracy, thereby completing the welding of the battery separator 53 and the battery base plate 51. During this process, the workbench 10 is rotated to a suitable welding angle through the rotating component 40, which helps to reduce welding blind spots and improve welding convenience.

[0043] The battery side plate 52 is positioned by the first positioning assembly 21, and the joints between the battery side plate 52 and the battery bottom plate 51, and the battery side plate 52 and the battery corner plate 54 are welded. In order to reduce welding deformation, the battery side plate 52 is welded in a symmetrical manner, and is welded gradually from both sides of the battery side plate 52 to the center.

[0044] The rotating assembly 40 drives the workbench 10 to rotate to the initial position, the first positioning assembly 21 releases the positioning of the battery side plate 52, the second positioning assembly 22 releases the positioning of the battery separator 53, the third positioning assembly 23 releases the positioning of the battery corner plate 54, and the magnetic seat 60 releases the positioning of the battery bottom plate 51, and removes the welded battery shell. In this embodiment, the workbench 10 rotates to the initial position to ensure that the battery shell is removed in the standard position, and at the same time unifies the operation process to provide convenience for the next batch of welding. The constraints of each positioning assembly are automatically released to prevent the battery shell from being damaged due to excessive clamping or jamming during disassembly. In addition, the release of positioning and magnetic locking are automatically controlled by the system, which reduces dependence on manual operation and improves work efficiency.

[0045] It should be noted that by first welding the battery bottom plate 51 and the diagonal battery corner plate 54, a preliminary battery shell frame structure is established to effectively disperse the thermal stress and avoid large-area deformation of the battery shell during welding. At the same time, diagonal welding can balance the thermal stress generated during welding and prevent local deformation of structural parts. Through staged welding, dynamic rotation and precise positioning, the thermal stress and deformation problems in the welding process are effectively reduced, the welding quality and efficiency are improved, and the structural strength and stability of the battery shell are improved.

[0046] Therefore, the present invention integrates the functions of rotation, positioning and locking. Through the positioning function of the first positioning component 21, the second positioning component 22, the third positioning component 23 and the magnetic base 60, the precise positioning of each component is ensured, and the operation is simple and efficient. Through the locking action of the first locking component 30, the stability of the battery housing during the welding process is guaranteed, and the welding error caused by movement is reduced. The rotating component 40 makes the welding operation more flexible, especially for welding of complex parts, which improves the convenience of operation and welding quality. The whole process is highly automated, reducing manual intervention, improving operational consistency and production efficiency. Staged welding ensures the strength and stability of each part, and finally forms a solid battery housing.

[0047] Working principle: The welding auxiliary tooling for a new energy blade battery shell provided by the present invention positions the battery shell 50 to be welded on the tooling table 10 through the positioning function of the positioning mechanism 20, thereby ensuring the stability of the battery shell during the welding process and avoiding welding defects caused by offset; The first rotating shaft 45 is driven to rotate by the rotating motor 47, which drives the first rotating frame 43 to move, and then the first rotating frame 43 drives the tooling table 10 to rotate, and drives the battery shell 50 to be welded to rotate, so that the tooling table 10 can rotate flexibly to meet the needs of different welding positions, reduce the workpiece adjustment time, and improve the welding efficiency.

[0048] The first locking assembly 30 and the second locking assembly 70 provide a reliable limiting function to ensure that the tooling table 10 and the battery housing 50 to be welded will not move accidentally during the welding process. Therefore, the welding auxiliary tooling for the new energy blade battery housing provided by the present invention simplifies the operation process, reduces the difficulty of operation, and improves the welding efficiency by integrating the functions of rotation, positioning and locking.
