Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] The following reference Figures 1 to 17 This application describes a welding apparatus according to some embodiments.

[0045] See Figures 1 to 6 , Figure 17 As shown, an embodiment of this application provides a welding apparatus, including: a first lifting mechanism 1, a welding mechanism 2, a second lifting mechanism 3, a positioning member 4, a protective cover 5, and a dust extraction pipe 6; wherein, the welding mechanism 2 is disposed on the first lifting mechanism 1, and the first lifting mechanism 1 is used to drive the welding mechanism 2 to move along a first preset direction; the positioning member 4 is disposed on the second lifting mechanism 3, and the second lifting mechanism 3 is used to drive the positioning member 4 to move along the first preset direction; the positioning member 4 is formed with a welding clearance notch 41 penetrating along the first preset direction;

[0046] The protective cover 5 is connected to the first lifting mechanism 1 and / or the second lifting mechanism 3, and the protective cover 5 can cover the outer periphery and top of the welding avoidance notch 41; the dust extraction pipe 6 is provided on the protective cover 5, and one end of the dust extraction pipe 6 is connected to the protective cover 5, and the other end of the dust extraction pipe 6 is connected to the dust extraction equipment outside the protective cover 5, and is used to extract the welding molten beads inside the protective cover 5.

[0047] As can be seen from the structure described above, the welding device of this application can be applied in the battery manufacturing process. The usage process is as follows: First, the battery to be welded is installed on the placement fixture 18. The connecting piece 15 and the cover plate 16 of the battery are located at the end of the placement fixture 18, and the connecting piece 15 is located above the cover plate 16. The placement fixture 18 is moved to the welding station. At this time, the connecting piece 15 is located below the welding mechanism 2, such as the laser head 21. The second lifting mechanism 3 drives the positioning component 4 to move and press down on the connecting piece 15. The first lifting mechanism 1 drives the welding mechanism 2, such as the laser head 21, to move down to the position and weld the connecting piece 15 and the cover plate 16. During this process, the protective cover 5 is set around and above the welding avoidance gap 41, thereby blocking the welding molten beads. The molten beads are sucked away by the dust extraction pipe 6.

[0048] As can be seen, the existing welding mechanism 2 has been modified in this application by adding a protective cover 5 to the outer periphery of the welding area. Thus, during the welding process of the connecting piece 15 and the cover plate 16, the protective cover 5 plays the role of shielding the molten beads. Furthermore, the molten beads inside the protective cover 5 are sucked away by the dust extraction equipment through the dust extraction pipe 6, preventing the molten beads from splashing into the interior of the battery casing 17. This improves the problem of molten beads splashing into the cell casing during the welding process, enhances the welding effect, and ensures the battery quality.

[0049] It should be noted that the welding device of this application can be used not only in the battery manufacturing process, but also in the preparation process of other products. In other words, this device can be used to weld other products, not just batteries.

[0050] In this embodiment, preferably, as follows: Figures 1 to 15 As shown, the protective cover 5 includes a first protective cover 51 and a second protective cover 52. The first protective cover 51 is connected to the first lifting mechanism 1, and the first lifting mechanism 1 is used to drive the first protective cover 51 and the welding mechanism 2 to move synchronously along a first preset direction.

[0051] The second protective cover 52 is connected to the positioning member 4. The second lifting mechanism 3 is used to drive the positioning member 4 and the second protective cover 52 to move synchronously along the first preset direction. The second protective cover 52 covers the outer periphery and top of the welding avoidance notch 41. Along the first preset direction, the first protective cover 51 is disposed above the second protective cover 52, and the two can be docked together and connected.

[0052] Based on the structure described above, the welding device provided in this application is used as follows: the placement fixture 18 is moved to the welding station, the second lifting mechanism 3 drives the positioning component 4 and the second protective cover 52 to move downwards, the positioning component 4 presses onto the connecting piece 15 on the placement fixture, the first lifting mechanism 1 drives the welding machine mechanism and the first protective cover 51 to move downwards synchronously, the first protective cover 51 presses down onto the second protective cover 52, that is, the first protective cover 51 and the second protective cover 52 are joined together, and the welding head 21 is used to weld the connecting piece 15 to the cover plate 16. During the welding process, the first protective cover 51 and the second protective cover 52 play the role of shielding the molten beads, and the molten beads in the protective cover 5 are sucked away by the dust extraction equipment through the dust extraction pipe 6, avoiding the molten beads from splashing into the inside of the battery casing 17, that is, improving the problem of molten beads splashing into the inside of the battery casing during the welding process, improving the welding effect, and ensuring the battery quality.

[0053] Furthermore, in this application, the protective cover 5 is designed as a split structure, which is installed on different lifting mechanisms. Compared with the overall protective cover 5 which is taller, the structure is more stable. Of course, the structure of the protective cover 5 is not limited to the split structure mentioned above. That is to say, it is not limited to the structure including the first protective cover 51 and the second protective cover 52 mentioned above. It can also be provided with only one, that is, only including the first protective cover 51 or the second protective cover 52. The height of the protective cover 5 can be increased accordingly, which can also play the role of blocking the welding beads.

[0054] In this embodiment, preferably, as follows: Figure 4 As shown, the welding device also includes a gas pipe connector 14, which is disposed on the second protective cover 52. One end of the gas pipe connector 14 extends into the interior of the second protective cover 52, and the other end of the gas pipe connector 14 extends into the exterior of the second protective cover 52, and can be connected to a blower.

[0055] As can be seen from the structure described above, the blowing device blows air into the protective cover 5 through the air pipe joint 14, thereby blowing up the dust and molten beads. Then, the dust extraction device sucks away the dust and molten beads through the dust extraction pipe 6, thereby preventing the molten beads from falling into the inside of the battery casing 17.

[0056] It should be noted that the air pipe connector 14 may not be provided, that is, air may not be blown into the interior of the protective cover 5. The specific choice depends on the actual needs.

[0057] In this embodiment, preferably, as follows: Figure 15 As shown, the welding device also includes a first support member 12, a second support member 8, a third support member 7, a slider 9, a slide rail 10, a guide post 11, and a spring; wherein, the slide rail 10 is disposed on the first lifting mechanism 1, and the slider 9 is slidably engaged with the slide rail 10; the third support member 7 is connected to the slider 9, and the first protective cover 51 is connected to the third support member 7; the first support member 12 is connected to the lifting mechanism;

[0058] The second support member 8 is connected to the first support member 12; the guide post 11 is fixedly connected to the second support member 8, the slider 9 is slidably connected to the guide post 11, and along the length direction of the guide post 11, the two ends of the spring are respectively connected to the second support member 8 and the slider 9 (the spring is not shown in the figure).

[0059] As can be seen from the structure described above, when the first protective cover 51 presses onto the second protective cover 52, the first protective cover 51 relies on the elastic force of the spring to precisely fit with the protective cover 5, thereby improving the protective effect and also playing a buffering role to avoid rigid collisions.

[0060] It should be noted that springs can also be omitted, depending on the specific needs.

[0061] In this embodiment, preferably, as follows: Figure 16 As shown, the third support member 7 includes a first clamping member 71, a second clamping member 72, and a first fastening member; wherein, the first clamping member 71 is connected to the slider 9, and the first clamping member 71 is clamped on one side of the first protective cover 51, the second clamping member 72 is clamped on the opposite side of the first protective cover 51, and the first clamping member 71 and the second clamping member 72 are detachably connected by the first fastening member.

[0062] As can be seen from the structure described above, the first protective cover 51 is clamped and fixed by the first clamping member 71 and the second clamping member 72, and the first fastening member, such as screws or bolts, is used for connection, making the overall structure more stable. Furthermore, the above is a detachable connection structure, which facilitates subsequent disassembly and maintenance operations.

[0063] Furthermore, preferably, the first clamping member 71 is an L-shaped plate, and the end of the horizontal portion of the L-shaped plate is provided with a first groove for cooperating with the first protective cover 51. Of course, it is not limited to this.

[0064] Furthermore, preferably, the second clamping member 72 is a flat plate structure, and the end of the flat plate structure is provided with a first groove for cooperating with the first protective cover 51. Of course, it is not limited to this.

[0065] Furthermore, preferably, the first fastening member can be bolted or screwed, and preferably, it can be locked horizontally onto the first clamping member 71 and the second clamping member 72.

[0066] In this embodiment, preferably, as follows: Figure 16 and Figure 17 As shown, along the first preset direction, the top and bottom of the first protective cover 51 are respectively formed with a first top opening 513 and a first bottom opening 514, and the top and bottom of the second protective cover 52 are respectively formed with a second top opening and a second bottom opening. The first bottom opening 514 and the second top opening can be connected together and communicate with each other. The second protective cover 52 is disposed on the outer periphery and above the welding avoidance notch 41 via the second bottom opening.

[0067] As can be seen from the structure described above, the welding head 21 of the welding mechanism 2, such as the laser head, can sequentially pass through the first top opening 513, the inside of the first protective cover 51, the first bottom opening 514, and the second top opening to extend into the inside of the second protective cover 52, and reach the welding clearance opening, where welding can be performed.

[0068] Furthermore, preferably, the second protective cover 52 is provided on the outer periphery and above the entire positioning member 4 via the second bottom opening, thereby achieving the shielding of the welding avoidance gap 41. Of course, it is not limited to this. The second protective cover 52 can also be located on the top of the positioning member 4, and it can only be provided on the outer periphery and above the avoidance gap. The specific choice depends on the actual needs.

[0069] In this embodiment, preferably, as follows: Figures 11 to 15 As shown, the first protective cover 51 includes a protective tube 511 and a first docking plate 512 connected to each other; wherein, along the first preset direction, the first docking plate 512 is disposed at the bottom of the protective tube 511 near the second protective cover 52, and the first docking plate 512 forms a first clearance notch corresponding to the first bottom opening 514 of the protective tube 511.

[0070] As can be seen from the structure described above, the protective pipe 511 can fully enclose the welding part, improve the shielding effect of molten beads, and occupy little space, with a simple structure and low material input; the first mating plate 512 of the first protective cover 51 can abut against the second mating plate 522 of the second protective cover 52 described below, thereby achieving a tight fit and improving the effect of preventing molten beads from splashing.

[0071] It should be noted that the structure of the first protective cover 51 is not limited to the above, and can also be designed according to actual needs. For example, the protective tube 511 can also be set as a shell structure of other shapes, as long as it can block the molten beads.

[0072] In this embodiment, preferably, as follows: Figure 4 and Figure 6 As shown, the welding device also includes a connecting member 13, which is connected to the second lifting mechanism 3, and the positioning member 4 is connected to the side of the connecting member 13 away from the second lifting mechanism 3.

[0073] As can be seen from the structure described above, the connecting member 13 serves to connect the positioning member 4 and the second lifting mechanism 3, that is, it acts as a transition, and provides sufficient installation space for the second protective cover 52. Of course, this connecting member 13 can also be omitted, and the positioning member 4 can be lengthened to meet the usage requirements.

[0074] In this embodiment, preferably, as follows: Figure 7 and Figure 8 As shown, the second protective cover 52 includes a main protective cover 521 and a second docking plate 522 and a baffle 523 respectively connected to the main protective cover 521; wherein, along the first preset direction, the top, bottom and sides of the main protective cover 521 are formed with openings.

[0075] The second docking plate 522 is disposed on the top of the main protective cover 521, and the second docking plate 522 has a second clearance notch corresponding to the top opening of the main protective cover 521; the second docking plate can be connected to the first docking plate 512; the baffle 523 is connected to the connecting member 13, and the baffle 523 blocks the side opening of the main protective cover 521.

[0076] As can be seen from the structure described above, the first docking plate 512 of the first protective cover 51 can abut against the second docking plate 522 of the second protective cover 52, thereby achieving a tight fit and improving the effect of preventing molten beads from splashing; the main protective cover 521 and the baffle 523 are arranged around the outer periphery of the positioning member 4, which serves to shield the molten beads.

[0077] Furthermore, preferably, the main protective cover 521 and the second docking plate 522 can be an integral structure, while the baffle 523 only abuts against the two side walls of the main protective cover 521 without being connected. Of course, it is not limited to this; the main protective cover 521 and the second docking plate 522 can also be separate structures, connected by buckles or bolts.

[0078] Furthermore, preferably, the second protective cover 52 also includes an auxiliary baffle 524, and the auxiliary baffle 524 is vertically connected to one side of the second docking plate 522.

One of the main protective cover 521 and the positioning member 4 forms an oblong hole 5211, while the other forms a threaded hole. The second fastening member is detachably installed in the oblong hole 5211 and the threaded hole.

[0080] As can be seen from the structure described above, by adjusting the position of the second fastening member in the oblong hole 5211, the position of the main protective cover 521 can be adjusted to meet different protection needs and has a wider range of applications. Of course, it is not limited to this. The main protective cover 521 can also be fixedly connected to the positioning member 4, or it can adopt a detachable connection method with a non-adjustable position. That is to say, both the main protective cover 521 and the positioning member 4 have threaded holes, rather than one having an oblong hole 5211 and the other having a threaded hole. The specific choice depends on the actual needs.

[0081] In this embodiment, preferably, as follows: Figure 1As shown, the aforementioned first lifting mechanism 1 and second lifting mechanism 3 are both existing structures. The first lifting mechanism 1 can be a structure with a motor and a lead screw. The motor drives the lead screw to rotate, which in turn moves the nut seat on the lead screw. The aforementioned welding mechanism 2 and the third support component 7 can also be ultimately connected to the nut seat through other structural components, thereby making vertical lifting and lowering movements with the nut seat. The second lifting mechanism 3 can be a structure with a cylinder block, a slide rail, and a slider. The telescopic end of the cylinder is connected to the slider, and the slider and the slide rail slide together. The aforementioned connecting component can also be ultimately connected to the slider through other structural components, thereby completing linear motion, that is, vertical lifting and lowering movements.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
