Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.
[0027] The following is combined with Figure 1 and Figure 5 This application describes the ultrasonic welding apparatus and busbar welding machine.
[0028] According to the embodiments of the first aspect of this application, such as Figure 1 and Figure 2 As shown, the ultrasonic welding device includes a busbar feeding assembly 41, a busbar placement seat 42, a busbar welding assembly 43, and a busbar moving assembly 44;
[0029] The busbar placement seat 42 is located between the busbar feeding component 41 and the busbar moving component 44. The busbar feeding component 41 is used to feed the busbar to the busbar placement seat 42.
[0030] The bus welding assembly 43 and the bus moving assembly 44 are arranged adjacent to each other. The bus moving assembly 44 is used to move the bus at the bus placement seat 42 to the bus welding assembly 43.
[0031] Busbar welding assembly 43 is used to weld busbars and wire harnesses together.
[0032] According to the ultrasonic welding apparatus of this application embodiment, the busbar feeding assembly 41 can move and feed the busbar to the busbar placement seat 42, where the busbar placement seat 42 can support the busbar. Then, the busbar moving assembly 44 moves the busbar from the busbar placement seat 42 to the busbar welding assembly 43, so that the busbar welding assembly 43 can weld the busbar and the wire harness together, realizing automated welding of the busbar and the wire harness. In other words, this application can realize automatic busbar feeding, automatically move the busbar to the busbar welding assembly 43, and automatically weld the busbar and the wire harness together through the busbar welding assembly 43, improving the automation level of welding of wire harness and busbar, and helping to improve production efficiency.
[0033] In some examples, the bus welding assembly 43 is, for example, an ultrasonic welded component.
[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the busbar feeding assembly 41 includes a busbar feeding rack 411, a busbar feeding drive 412, and a busbar feeding adsorption component 413. The busbar feeding drive 412 is installed on the busbar feeding rack 411, and the busbar feeding adsorption component 413 is connected to the busbar feeding drive 412. The busbar feeding adsorption component 413 is used to adsorb the busbar, and the busbar feeding drive 412 is used to drive the busbar feeding adsorption component 413 to move to the busbar placement seat 42.
[0035] Understandably, the busbar loading rack 411 can support the busbar loading drive 412. The busbar loading drive 412 can drive the busbar loading adsorption component 413 to move, so that the busbar loading adsorption component 413 with the busbar adsorbed can move to the busbar placement seat 42. Then, the busbar loading adsorption component 413 releases the busbar, thus moving the busbar to the busbar placement seat 42, realizing the automatic movement of the busbar.
[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, the busbar feeding assembly 41 also includes a busbar turntable 414, which has multiple busbar receiving cavities for accommodating the busbars. The busbar turntable 414 can drive the multiple busbar receiving cavities to move and rotate to below the busbar feeding adsorption component 413.
[0037] Understandably, a certain number of manifolds are placed in each manifold receiving cavity of the manifold turntable 414. The manifold turntable 414 can drive multiple manifold receiving cavities to rotate sequentially to the bottom of the manifold feeding adsorption component 413, so that the manifold feeding adsorption component 413 can adsorb the manifolds. Then, the manifold feeding drive component 412 moves the manifold feeding adsorption component 413 and the manifolds to the manifold placement seat 42, thereby realizing the automatic feeding of the manifolds.
[0038] It should be noted that the manifold turntable 414 can rotate only after the manifolds in one of the manifold receiving chambers have been consumed, so that the next manifold receiving chamber moves below the manifold feeding adsorption member 413. Alternatively, the manifold turntable 414 can rotate only after the manifold feeding adsorption member 413 has adsorbed one manifold from one of the manifold receiving chambers, so that the next manifold receiving chamber moves below the manifold feeding adsorption member 413.
[0039] In some examples, the busbar loading drive 412 includes a lateral drive and a vertical drive. The lateral drive is used to drive the vertical drive to move laterally, and the vertical drive is used to drive the busbar loading adsorption component 413 to move vertically.
[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the busbar feeding suction component 413 includes a lifting drive component 4131 and a busbar feeding suction cup 4132. The lifting drive component 4131 is connected to the busbar feeding drive component 412, and the busbar feeding suction cup 4132 is connected to the lifting drive component 4131. The lifting drive component 4131 is used to drive the busbar feeding suction cup 4132 to move up and down relative to the busbar turntable 414.
[0041] Understandably, the busbar loading drive 412 can drive the lifting drive 4131 to move between the busbar turntable 414 and the busbar placement seat 42, and the busbar loading suction cup 4132 will move together between the busbar turntable 414 and the busbar placement seat 42. When the manifold loading suction cup 4132 moves above the manifold receiving cavity, the lifting drive component 4131 drives the manifold loading suction cup 4132 to move downward, so that the manifold loading suction cup 4132 can be adsorbed onto the manifold. Then, the lifting drive component 4131 drives the manifold loading suction cup 4132 to move upward, and the manifold loading drive component 412 drives the lifting drive component 4131 and the manifold loading suction cup 4132 to move towards the manifold placement seat 42. When the manifold loading suction cup 4132 moves to the manifold placement seat 42, the lifting drive component 4131 drives the manifold loading suction cup 4132 to move downward, so as to place the manifold at the manifold placement seat 42, thereby realizing the automatic loading of the manifold.
[0042] In some embodiments, the bus placement seat 42 is formed with a bus limiting groove for placing the bus.
[0043] Understandably, the busbar limiting groove can limit the busbar, allowing it to be stably placed on the busbar placement seat 42.
[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the bus moving assembly 44 includes a bus moving drive 441 and a bus moving adsorption component 442. The bus moving adsorption component 442 is connected to the bus moving drive 441 and is used to adsorb the bus. The bus moving drive 441 is used to drive the bus moving adsorption component 442 to move between the bus placement seat 42 and the bus welding assembly 43.
[0045] Understandably, the bus moving drive 441 can drive the bus moving adsorption component 442 to move to the bus placement seat 42, so that the bus moving adsorption component 442 can adsorb the bus at the bus placement seat 42. Then, the bus moving drive 441 drives the bus moving adsorption component 442 to move to the bus welding assembly 43, so that the bus welding assembly 43 can weld the wire harness and the bus together.
[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the number of manifold moving adsorption components 442 is at least two. The at least two manifold moving adsorption components 442 include a first adsorption component 4421 and a second adsorption component 4422. The first adsorption component 4421 and the second adsorption component 4422 are both connected to the manifold moving drive component 441. The first adsorption component 4421 and the second adsorption component 4422 are arranged at intervals. The manifold moving drive component 441 is used to drive the first adsorption component 4421 to move between the manifold placement seat 42 and the manifold welding assembly 43. The manifold moving drive component 441 is also used to drive the second adsorption component 4422 to move between the manifold welding assembly 43 and the next work station.
[0047] Understandably, the bus moving drive 441 can simultaneously move the first suction member 4421 and the second suction member 4422. While the bus moving drive 441 moves the first suction member 4421 to the bus placement seat 42, the second suction member 4422 moves to the bus welding assembly 43. After the first suction member 4421 attaches to the bus at the bus placement seat 42, and the bus welding assembly 43 completes the welding connection between the wire harness and the bus, the bus moving drive 441 moves the first suction member 4421 to the bus welding assembly 43 to move the bus. Simultaneously, the second suction member 4422 moves the bus with the welded wire harness to the next station, achieving simultaneous movement of both unwelded and welded busbars, thus improving efficiency.
[0048] Specifically, such as Figure 1 and Figure 2 As shown, the busbar moving assembly 44 also includes a busbar moving connecting frame 443, which is connected to the busbar moving drive component 441. The first adsorption component 4421 and the second adsorption component 4422 are both connected to the busbar moving connecting frame 443, so that the busbar moving drive component 441 can simultaneously drive the first adsorption component 4421 and the second adsorption component 4422 to move.
[0049] It should be noted that the distance between the first adsorption element 4421 and the second adsorption element 4422, the distance between the busbar placement seat 42 and the busbar welding assembly 43, and the distance between the busbar welding assembly 43 and the next work station are all the same.
[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the manifold moving suction component 442 includes a telescopic drive component 4423 and a manifold moving suction cup 4424. The telescopic drive component 4423 is connected to the manifold moving drive component 441, and the manifold moving suction cup 4424 is connected to the telescopic drive component 4423. The manifold moving drive component 441 is used to drive the telescopic drive component 4423 to move along a first direction, and the telescopic drive component 4423 is used to drive the manifold moving suction cup 4424 to move along a second direction. The first direction and the second direction are perpendicular to each other.
[0051] Understandably, through the cooperation of the busbar moving drive 441 and the telescopic drive 4423, the position of the busbar moving suction cup 4424 can be adjusted in the first and second directions, so that the busbar moving suction cup 4424 can be accurately moved to the busbar placement seat 42 or the busbar welding assembly 43.
[0052] In some embodiments, such as Figure 3As shown, the ultrasonic welding apparatus includes:
[0053] Ultrasonic welding base 45, used to support the busbar;
[0054] The wire harness clamping assembly 46 is connected to the ultrasonic welding base 45 and is used to clamp the wire harness.
[0055] Busbar welding assembly 43 is located above ultrasonic welding base 45 and is used to weld busbars and wire harnesses together.
[0056] According to the ultrasonic welding apparatus of this application embodiment, a busbar is placed on an ultrasonic welding base 45, and then a wire harness is moved to the busbar and clamped by a wire harness clamping assembly 46 to keep the wire harness stable. Then, the busbar welding assembly 43 welds the busbar and the wire harness together, thus achieving automated welding connection between the busbar and the wire harness. In other words, this application uses the wire harness clamping assembly 46 to keep the wire harness stable, preventing it from shaking or shifting during welding and ensuring the welding effect between the busbar and the wire harness.
[0057] In some embodiments, such as Figure 3 As shown, the wire harness clamping assembly 46 includes a wire harness clamping drive 461 and two wire harness clamping parts 462. The wire harness clamping drive 461 is connected to the ultrasonic welding base 45, and the two wire harness clamping parts 462 are connected to the wire harness clamping drive 461. The wire harness clamping drive 461 is used to drive the two wire harness clamping parts 462 to move closer or further away from each other in order to clamp or release the wire harness.
[0058] Understandably, the wire harness clamping drive 461 drives the two wire harness clamping parts 462 to move away from each other, facilitating the movement of the wire harness between the two clamping parts 462 so that the end of the wire harness abuts against the busbar. Then, the wire harness clamping drive 461 drives the two clamping parts 462 to move closer together, clamping the wire harness and securing it. This effectively prevents the end of the wire harness from shaking or moving during welding, ensuring a good welding result between the wire harness and the busbar. After welding the wire harness to the busbar is complete, the wire harness clamping drive 461 drives the two clamping parts 462 to move away from each other, releasing the wire harness and allowing the busbar with the welded wire harness to move to the next station.
[0059] Specifically, the first end of the wire harness clamping part 462 is connected to the wire harness clamping drive member 461, and the second end of the wire harness clamping part 462 protrudes from the ultrasonic welding base 45.
[0060] It is understandable that the second end of the wire harness clamping part 462 is used to clamp the wire harness. If the second end of the wire harness clamping part 462 is lower than the ultrasonic welding base 45, the wire harness clamping part 462 will pull the wire harness downwards when clamping it, causing the end of the wire harness to curl up, which in turn prevents the end of the wire harness from maintaining contact with the busbar. Therefore, in this embodiment, the second end of the wire harness clamping part 462 is set to protrude from the ultrasonic welding base 45, so that the wire harness clamping part 462 will not affect the contact between the wire harness and the busbar while clamping the wire harness, thus avoiding any impact on the welding quality of the wire harness and the busbar.
[0061] In some embodiments, the ultrasonic welding base 45 is formed with a welding mounting groove for accommodating a busbar.
[0062] Understandably, the welding mounting groove can limit the movement of the busbar, ensuring the stability of the busbar at 45° on the ultrasonic welding base.
[0063] In some embodiments, the ultrasonic welding base 45 is formed with a wire harness communication structure, which is connected to the welding mounting groove so that the wire harness can be inserted into the welding mounting groove through the wire harness communication structure.
[0064] It is understandable that by forming a wire harness connecting structure at the ultrasonic welding base 45, the end of the wire harness can be inserted through the wire harness connecting structure and located in the welding mounting groove, so that the end of the wire harness can abut against the busbar in the welding mounting groove.
[0065] In some examples, the wiring harness connection structure is, for example, a hole or notch or any other suitable connection structure.
[0066] According to an embodiment of the second aspect of this application, such as Figure 4 As shown, the busbar welding machine includes the ultrasonic welding device described above.
[0067] According to the busbar welding machine of this application embodiment, the busbar is placed on the ultrasonic welding base 45, and then the wire harness is moved to the busbar and clamped by the wire harness clamping assembly 46 to keep the wire harness stable. Then, the busbar welding assembly 43 welds the busbar and the wire harness together, thereby realizing the automated welding connection between the busbar and the wire harness. In other words, this application uses the wire harness clamping assembly 46 to clamp the wire harness, which keeps the wire harness stable and prevents the wire harness from shaking or shifting during welding, thus ensuring the welding effect between the busbar and the wire harness.
[0068] In some embodiments, such as Figure 4 and Figure 5 As shown, the busbar welding machine also includes a main body 47, and the ultrasonic welding device is spaced apart from the main body 47.
[0069] It is understandable that the ultrasonic welding device is spaced apart from the main body 47 to prevent the main body 47 from vibrating when the ultrasonic welding device is working, thus avoiding affecting other work positions on the main body 47.
[0070] Specifically, such as Figure 4 and Figure 5 As shown, the busbar welding machine also includes a mounting column 48, an ultrasonic welding device is connected to the first end of the mounting column 48, the second end of the mounting column 48 is connected to the ground, and the mounting column 48 is spaced apart from the main body 47.
[0071] It is understandable that the mounting column 48 is directly connected to the ground and spaced apart from the main body 47. Connecting the ultrasonic welding device to the mounting column 48 can separate the ultrasonic welding device from the main body 47 while installing the ultrasonic welding device, so as to prevent the main body 47 from vibrating when the ultrasonic welding device is working.
[0072] In some embodiments, such as Figure 4 and Figure 5 As shown, the ultrasonic welding device also includes a busbar welding base plate 49, a busbar welding assembly 43 and an ultrasonic welding base 45 connected to the same side of the busbar welding base plate 49, and the busbar welding base plate 49 and the main body 47 are spaced apart.
[0073] Understandably, connecting the busbar welding assembly 43 and the ultrasonic welding base 45 simultaneously to the same side of the busbar welding base plate 49 facilitates the welding operation of the busbar by the busbar welding assembly 43 on the busbar at the ultrasonic welding base 45. Meanwhile, the busbar welding base plate 49 is spaced apart from the main body 47, thus preventing vibration of the main body 47 during ultrasonic welding of the busbar.
[0074] Specifically, the side of the busbar welding base plate 49 facing away from the busbar welding assembly 43 is connected to the first end of the mounting post 48.
[0075] It should be noted that in this application, the driving component may be, for example, a motor, a cylinder, or any other suitable driving structure. Furthermore, since the driving component is an existing part, its specific structure and working principle will not be described in detail here.
[0076] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
