[0036] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 9 The embodiments of the present application are described in detail.

[0037] like Figures 4 to 9As shown, the present application provides a welding device 1 for welding a workpiece 2 to be welded, and the welding device 1 includes a clamping assembly 11 and a welding assembly 12. The clamping assembly 11 includes a clamping member 112 for clamping the workpiece 2 to be welded; the welding assembly 12 includes a pressure member 121 and a laser emitter 122. The clamping member 111 and the pressure member 121 are correspondingly arranged along the vertical direction X, and the distance between the two along the vertical direction X is variable; the laser emitter 122 is arranged toward the clamping member 111, and the clamping member 111 can rotate around its own axis and / or the laser emitter 122 can rotate around the clamping member 111 to form a weld on the periphery of the workpiece 2 to be welded.

[0038] The part to be welded 2 can be any material that needs to be welded together. The part to be welded 2 can be cylindrical, cubic, or irregular in shape, and the embodiments of the present application are not limited thereto. For example, the part to be welded 2 can be a cylindrical battery. In the field of cylindrical batteries, as manufacturing capacity and battery energy density continue to improve, the length of cylindrical batteries is getting longer and longer. In existing welding manufacturing, the cylindrical battery lies flat during welding (i.e., the length direction of the cylindrical battery is horizontal), which causes the welding device to occupy an increasingly larger area, seriously reducing production capacity.

[0039] The clamping member 111 is a component for clamping and fixing the workpiece 2 to be welded. Specifically, the clamping member 111 can be an adsorption device such as a negative pressure device, or a clamping device such as a clamping claw.

[0040] In some embodiments, the welding device 1 only completes the welding function, the first welding part 21 and the second welding part 22 of the incoming part 2 to be welded have been pre-assembled, and the pressure part 121 only plays the role of applying pressure, that is, pressing the first welding part 21 and the second welding part 22 in the part 2 to be welded to a preset position to ensure the connection accuracy between the first welding part 21 and the second welding part 22.

[0041] In other embodiments, the welding device 1 performs both assembly and welding functions. In this case, the pressure member 121 also serves as a component for clamping and securing the workpiece 2 to be welded. Upon receiving incoming materials, the first welding part 21 and the second welding part 22 are clamped and secured in the clamping member 111 and the pressure member 121, respectively. When the clamping member 111 and the pressure member 121 approach each other vertically, the first welding part 21 and the second welding part 22 are first assembled and pressed together, followed by welding of the workpiece 2 to be welded. It should be noted that the pressure member 121 can also be a suction device such as a negative pressure device or a device such as a clamping jaw.

[0042] The laser emitter 122 is a component that can emit laser light, thereby heating and melting the parts 2 to be welded together.

[0043] The clamping member 111 and the pressure member 121 are arranged correspondingly along the vertical direction X, so that the workpiece 2 to be welded is clamped between the clamping member 111 and the pressure member 121. On the one hand, a clamping force along the vertical direction X can be applied to the workpiece 2 to be welded to ensure the assembly accuracy of the first welding part 21 and the second welding part 22 in the vertical direction and improve the welding quality. On the other hand, the workpiece 2 to be welded can be arranged in the welding device 1 along the vertical direction to reduce the footprint of the welding device 1.

[0044] The distance between the clamping member 111 and the pressure member 121 along the vertical direction X is variable, that is, the clamping member 111 and the pressure member 121 can move closer to or farther away from each other along the vertical direction X. On the one hand, a pressing force can be provided to assemble the first welding member 21 and the second welding member 22 together to facilitate the welding connection therebetween; on the other hand, it facilitates the blanking of the workpiece 2 to be welded after welding. Specifically, in some embodiments, the clamping member 111 can be moved along the vertical direction X to change the distance between the clamping member 111 and the pressure member 121 along the vertical direction X; in other embodiments, the pressure member 121 can be moved along the vertical direction X to change the distance between the clamping member 111 and the pressure member 121 along the vertical direction X; in yet other embodiments, both the clamping member 111 and the pressure member 121 can be moved along the vertical direction X to change the distance between the clamping member 111 and the pressure member 121 along the vertical direction X, with fast movement speed and high efficiency.

[0045] In some embodiments, the clamping member 111 and / or the pressure member 112 can be moved in the horizontal direction to ensure that the direction of the pressing force between the pressure member 121 and the clamping member 111 is parallel to or even coincides with the axis of the workpiece 2 to be welded, thereby preventing the direction of the provided pressing force from being non-parallel to the axis of the workpiece 2 to be welded, thereby preventing the workpiece 2 from being skewed or deformed. When the pressure member 121 also has a clamping function, the clamping member 111 and / or the pressure member 112 can be moved in the horizontal direction. The concentricity between the first weld 21 and the second weld 22 can be ensured by adjusting the relative positions of the clamping member 111 and the pressure member 121 in the horizontal direction.

[0046] The clamping member 111 can rotate about its own axis and / or the laser emitter 122 can rotate about the clamping member 11. That is, in some embodiments, the clamping member 111 can rotate about its own axis while the laser emitter is fixed. When the clamping member 111 rotates about its own axis, it drives the workpiece 2 to be welded, which is clamped on the clamping member 111, to rotate, so that the workpiece 2 to be welded and the laser emitter 122 move relative to each other, thereby forming a weld seam on the periphery of the workpiece 2 to be welded. In other embodiments, the laser emitter 122 can rotate about the clamping member 111 while the clamping member 111 is fixed. This can also cause relative movement between the workpiece 2 to be welded and the laser emitter 122, thereby forming a weld seam on the periphery of the workpiece 2 to be welded. In still other embodiments, the clamping member 111 can rotate about its own axis and the laser emitter 122 can rotate about the clamping member 111, thereby accelerating the relative movement between the workpiece 2 to be welded and the laser emitter 122, thereby increasing the welding speed.

[0047] In some embodiments, the laser emitter 122 can move horizontally and the clamping member 111 can rotate about its own axis, so that the distance between the laser emitter 122 and the workpiece 2 to be welded can be adjusted during the welding process, thereby improving the welding quality. For example, when welding square or irregularly shaped materials, the distance between the outer peripheral surface of the workpiece 2 to be welded and the laser emitter 122 is constantly changing as the workpiece 2 to be welded rotates. At this time, by changing the horizontal position of the laser emitter 122, the distance between the laser emitter 122 and the outer peripheral surface of the workpiece 122 to be welded can be adjusted at any time, ensuring that the distance between the outer peripheral surface of the workpiece 2 to be welded and the laser emitter 122 remains unchanged. This allows the laser emitter 122 to avoid changing its focal length during welding, thereby improving the welding quality and consistency.

[0048] By arranging the clamping member 111 and the pressure member 121 in correspondence along the vertical direction X, the workpiece 2 to be welded is clamped vertically between the clamping member 111 and the pressure member 121, thereby ensuring the assembly accuracy of the two. Subsequently, the clamping member 121 rotates around its own axis and / or the laser emitter 122 rotates around the clamping member 111, so that the laser emitted by the laser emitter 122 moves around the periphery of the workpiece 2 to be welded and forms an annular weld around the periphery of the workpiece 2 to be welded, thereby achieving welding of the workpiece 2 to be welded. Compared with existing horizontally arranged welding devices, the welding device 1 of the present application arranges the workpiece 2 to be welded vertically, which can reduce the footprint of the welding device 1 when producing longer workpieces 2 to be welded, thereby improving production efficiency.

[0049] like Figures 4 to 7 As shown, in some embodiments, the part to be welded 2 is cylindrical, the clamping member 111 can rotate around its own axis and the axis of the part to be welded 2 coincides with the axis of the clamping member 111, and the clamping assembly 11 also includes a mounting member 112 and a rotating shaft 113, one end of the rotating shaft 113 is connected to the clamping member 111, and the other end is rotatably connected to the mounting member 112.

[0050] The axis of the workpiece 2 to be welded coincides with the axis of the clamping member 111, so that the workpiece 2 to be welded also rotates around its own axis as the clamping member 111 rotates. This ensures that the relative distance between the outer peripheral surface of the workpiece 2 to be welded and the laser emitter 122 remains unchanged, so that the focal length of the laser emitter 122 does not need to be changed during welding, thereby improving the welding quality and consistency.

[0051] One end of the rotating shaft 113 is connected to the clamping member 111 so that when the rotating shaft 113 rotates, it can drive the clamping member 11 to rotate. The rotating shaft 113 and the clamping member 111 can be connected by a detachable connection method such as bolts and clamping, or by a non-detachable connection method such as welding and gluing. The embodiment of the present application does not limit this.

[0052] The base 113 and the rotating shaft 112 are provided to realize the rotation of the clamping member 111 around its own axis, which has a simple structure and reliable movement.

[0053] like Figure 5 and Figure 7 As shown, in some embodiments, the clamping member 111 is a pneumatic three-jaw chuck 111 , the rotating shaft 113 is a hollow structure, and the gas connecting pipe 1111 of the pneumatic three-jaw chuck 111 is disposed in the hollow structure.

[0054] By configuring the clamping member 111 as a three-jaw chuck, the concentricity between the workpiece 2 to be welded and the clamping member 111 can be ensured when the workpiece 2 is clamped therein, thereby improving welding precision and quality. Secondly, configuring the clamping member 111 as a pneumatic three-jaw chuck uses compressed air to control the tightening and loosening of the clamping member 111, making control convenient and inexpensive.

[0055] The rotating shaft 113 is a hollow structure. The cross-section of the hollow structure can be a regular shape such as a square or a circle, or an irregular shape, which is not limited in this embodiment of the present application. By making the rotating shaft 113 a hollow structure, on the one hand, it can save material and reduce the weight of the clamping assembly 11. On the other hand, it can also accommodate the gas connection tube 1111 of the pneumatic three-jaw chuck inside the rotating shaft 113, saving space and facilitating maintenance of the welding device 1.

[0056] In some embodiments, when the pressure member 121 also has a clamping function, the pressure member 121 can also be set as a three-jaw chuck to ensure the concentricity between the second welding member 22 clamped in the pressure member 121 and the pressure member 121, thereby ensuring the concentricity between the first welding member and the second welding member 22.

[0057] like Figures 4 to 7As shown, in some embodiments, the welding device 1 further includes a frame 13 and a drive assembly 14. The mounting member 112 is slidably connected to the frame 13 along the vertical direction X; and the drive assembly 14 is drivingly connected to the mounting member 112.

[0058] The frame 13 is a component fixedly connected to the ground, that is, there is no relative movement between the frame 13 and the ground, and the two are always in a relatively static state.

[0059] The sliding connection between the mounting member 112 and the frame 13 can be achieved through a guide rail and slider mechanism, or through a rack and pinion mechanism.

[0060] The drive assembly 14 is a component capable of providing driving force. For example, when the mounting member 112 and the frame 13 are connected via a guide rail and slider mechanism, the drive assembly 14 can be a component such as a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder to propel the mounting member 112 to move in the vertical direction X. When the mounting member 112 and the frame 13 are connected via a rack and pinion mechanism, the drive assembly 14 can be a motor to drive the gear to rotate, which in turn drives the rack to move in the vertical direction X, thereby achieving movement of the mounting member 112 in the vertical direction X.

[0061] like Figure 5 and Figure 7 As shown, in some embodiments, the frame 13 is provided with a guide rail 131 extending in the vertical direction X, and the mounting member 112 is provided with a slider 1121 movably mounted on the guide rail 131; or the mounting member 112 is provided with a guide rail (not shown) extending in the vertical direction X, and the frame 13 is provided with a slider (not shown) movably mounted on the guide rail. That is, one of the guide rail 131 and the slider 1121 is provided on the frame 13, while the other is provided on the mounting member 112. The movement of the slider 1121 on the guide rail 131 enables the mounting member 112 to move in the vertical direction X. This provides a simple structure and reliable movement.

[0062] like Figure 8 and Figure 9 As shown, in some embodiments, the driving assembly 14 includes a push rod 141 and a power source 142. The push rod 141 is disposed at an end of the mounting member 112 away from the clamping member 111; the power source 142 is drivingly connected to the push rod 141 to drive the push rod 141 to move along the vertical direction X.

[0063] By providing the power source 142 and the push rod 141 , when the power source 142 drives the push rod 141 to move along the vertical direction X, the push rod 141 can push the mounting member 112 to move along the vertical direction X, thereby achieving movement of the clamping member 111 along the vertical direction X.

[0064] In some embodiments, the push rod 141 and the frame 13 may be slidably connected to each other to enable the push rod 141 to move along the vertical direction X. Specifically, a guide rail extending along the vertical direction X may be provided on one of the push rod 141 and the frame 13, and a slider may be provided on the other, and the movement of the slider on the guide rail enables the push rod 141 to move along the vertical direction X.

[0065] like Figure 9 As shown, in some embodiments, the driving assembly 14 further includes a pressure detector 143 , which is disposed on a side of the push rod 141 facing away from the mounting member 112 .

[0066] By setting up a pressure detector 143, the pressure applied by the driving component 14 on the clamping component 11 can be detected, and then the pressure between the first welding part 21 and the second welding part 22 can be detected, thereby preventing the first welding part 21 and the second welding part 22 from being damaged by excessive pressure and ensuring production quality.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the welding assembly 12 further includes a detection member 123 , and the detection member 123 is disposed toward the pressure member 121 .

[0068] Specifically, in some embodiments, the detection member 123 may be a laser detector that detects whether the workpiece 2 to be welded is properly clamped on the clamping member 111 corresponding to the pressure member 121 by emitting laser light. In other embodiments, the detection member 123 may also be a CCD image recognition device that detects whether the workpiece 2 to be welded is properly clamped on the clamping member 111 corresponding to the pressure member 121 by taking pictures and performing image recognition.

[0069] By providing the detection member 123 , the position of the workpiece 2 to be welded can be detected, ensuring that the workpiece 2 to be welded is clamped and fixed at an accurate position, thereby ensuring the connection accuracy of the first welding member 21 and the second welding member 22 .

[0070] like Figures 1 to 3 As shown, another aspect of the present application provides a welding device, comprising a welding apparatus 1, a conveying apparatus 3, and a material transfer apparatus 4. The welding apparatus 1 comprises a plurality of clamping assemblies 11; the conveying apparatus 3 is configured to sequentially convey the plurality of clamping assemblies 11 to a welding assembly 12 along a predetermined direction; and the material transfer apparatus 4 is disposed upstream of the welding assembly 12 along a predetermined direction.

[0071] The conveying device 3 can be a conveyor belt, a chain, a turntable, etc., and the embodiments of the present application do not limit this. The conveying device 3 conveys the multiple clamping components 11 to the welding component 12 in sequence along a preset direction, and the preset direction is also the conveying direction of the conveying device 3. In some embodiments, the preset direction can be a unidirectional direction such as a straight line or a curve. At this time, a material transfer device 4 is respectively set at the starting position and the end position of the preset direction to complete the loading and unloading of the workpiece 2 to be welded. In other embodiments, the preset direction can also be a closed figure surrounded by straight lines and / or curves, such as a polygon, a circle, etc. At this time, the workpiece 2 to be welded will return to the starting position again after being conveyed by the conveying device 3. Therefore, the same material transfer device 4 can be used to complete the loading and unloading of the workpiece 2 to be welded, saving costs.

[0072] The material transfer device 4 refers to a component that can transfer the parts to be welded 2. In some embodiments, the material transfer device 4 completes the loading or unloading of the parts to be welded 2; in other embodiments, the material transfer device 4 completes both the loading and unloading of the parts to be welded 2.

[0073] The material transfer device 4 is arranged upstream of the welding assembly 12 along a preset direction, that is, the clamping assembly 11 first reaches the material transfer device 4 under the transportation of the conveying device 3, completes the loading and / or unloading of the workpiece 2 to be welded, and then is transported to the welding assembly 12 to complete the welding of the workpiece 2 to be welded.

[0074] By setting up a conveying device 3 and multiple clamping components 11, multiple clamping components 11 are sequentially conveyed to the welding component 12, and loading and unloading and welding are dispersed in different processes, so that the material transfer and welding processes can be carried out at the same time, thereby improving production efficiency.

[0075] like Figure 3 As shown, in some embodiments, the conveying device 1 is a turntable, the turntable is a regular polygon and the center of rotation coincides with the center of the regular polygon, a plurality of clamping components 11 are arranged at intervals along the edges of the regular polygon, and the material transfer device 4 and the welding component 12 are respectively arranged corresponding to different edges of the regular polygon.

[0076] The conveying device 1 is set as a turntable, and when the turntable rotates, the clamping assembly 11 moves along a preset circular direction. Therefore, the same material transfer device 4 can be used to realize the loading and unloading of the workpiece 2 to be welded, which saves costs and reduces the floor space of the welding equipment, further improving production efficiency.

[0077] By configuring the turntable to be a regular polygon with its center of rotation coinciding with the center of the regular polygon, and rotating the turntable at an angle a (a = 360° / n, where n is the number of sides of the regular polygon), the relative positions of the material transfer device 11, the welding assembly 12, and the adjacent clamping assembly 11 to be operated can be maintained, thereby facilitating control of the welding equipment. For example, if the turntable is a square, each rotation of the turntable is 90°, which ensures that the relative positions of the clamping assembly 11 located on the side of the square adjacent to the material transfer device 4 and the material transfer device 4 remain unchanged, facilitating loading and unloading of the material transfer device 4. Similarly, the relative positions of the clamping assembly 11 located on the side of the square adjacent to the welding assembly 12 and the welding assembly 12 also remain unchanged.

[0078] It should be noted that one clamping component 11 or multiple clamping components 11 can be set on each side of the regular polygon, and the same number of clamping components 11 or different numbers of holding components 11 can be set on different sides. The embodiment of the present application does not limit this.

[0079] Multiple clamping assemblies 11 are arranged at intervals along the edges of the regular polygon. That is, when multiple clamping assemblies 11 are arranged on one side of the regular polygon, the straight line formed by connecting the clamping assemblies 11 is parallel to the edge of the regular polygon, so as to facilitate loading and unloading and welding of the welding equipment.

[0080] In some embodiments, the same number of clamping assemblies 11 are provided on each side of the regular polygon, and the number of welding assemblies 12 is also the same as the number of clamping assemblies 11. This allows for simultaneous welding of multiple parts 2 to be welded, while ensuring that all parts to be welded in the clamping assemblies 11 on each side can be welded in one welding process, facilitating control of the turntable.

[0081] For the convenience of description, the following description is made by taking the example of four clamping assemblies 11 provided on each side of the turntable. Figures 1 to 9 As shown, during loading, the material transfer device 4 loads the four parts to be welded 2 into the clamping assembly 11, and the parts to be welded 2 are clamped and fixed in the clamping assembly 11 by the pneumatic three-jaw chuck 111. Then the turntable rotates to transport the loaded clamping assembly 11 to the welding station, and the welded clamping assembly 11 or the empty clamping assembly 11 is transported to the material transfer station to complete the next loading and unloading.

[0082] After arriving at the welding station, the power source 142 drives the push rod 141 to move in the vertical direction X, thereby pushing the clamping member 111 toward the pressure member 121 in the vertical direction until the end of the workpiece 2 to be welded facing away from the clamping member 111 abuts against the pressure member 121. At the same time, the pressure detection member 143 and the detection member 123 respectively detect the pressure and relative position between the first welding member 21 and the second welding member 22. After confirming that the pressure and relative position between the first welding member 21 and the second welding member 22 meet the preset conditions, the rotating shaft 113 drives the clamping member 111 and the workpiece 2 to be welded to rotate, and at the same time, the laser emitter 122 emits a laser to weld the first welding member 21 and the second welding member 22 together. After welding is completed, the turntable continues to rotate and transports the welded workpiece 2 to the material transfer station, while also transporting the new, unfinished workpiece 2 to be welded on the clamping assembly 11 to the welding station.

[0083] After the welding is completed, the clamping assembly 11 arrives at the material transfer station, and the welded workpiece 2 to be welded is removed from the clamping assembly 11 by the material transfer device 4 and a new unfinished welded workpiece 2 to be welded is placed in the clamping assembly 11 to complete the loading of the welded workpiece 2.

[0084] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
