Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and specifically to an automatic welding device for processing new energy electric vehicle components. Background Art

[0002] A new energy electric vehicle refers to a vehicle powered by an on-vehicle power source and driven by an electric motor to drive the wheels. Among them, the battery frame is an important structural component in an electric vehicle for supporting and protecting the battery pack, and plays an important role in the safety and performance of the battery pack and the overall stability of the vehicle.

[0003] However, there are the following defects in the process of welding and combining the battery frame:

[0004] 1. When welding the battery frame, some accessories need to be welded outside the frame, such as lugs. The battery is installed on the vehicle frame through the lugs. When welding the lugs, the lugs need to be welded outside the frame in sequence. However, welding in sequence is time-consuming and laborious, and multiple positioning makes the error between welding positions increase.

[0005] 2. After welding the battery frame and accessories such as lugs, the overall frame has a large self-weight. And during the welding process, due to the obstruction of fixture and other fixing devices, when a worker moves one end of the frame upward to take out the frame, it not only brings a large labor intensity to the worker, but also the frame may be stressed at one end due to the obstruction of the fixture, causing the frame to be squeezed and deformed.

[0006] Therefore, the present invention proposes an automatic welding device for processing new energy electric vehicle components to make up for and improve the deficiencies of the existing technology. Summary of the Invention

Specific embodiments

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Refer to Figure 1 and Figure 3 As shown in [relevant figures], an automatic welding device for processing new energy electric vehicle components in this embodiment includes brackets 1 symmetrically arranged on the left and right. A welding robot 14 is fixedly connected to the front parts of the two brackets 1. A support plate 11 is rotatably connected symmetrically left and right between the two brackets 1. A third motor 13 is fixedly connected to the side of the right bracket 1, and the output end of the third motor 13 is fixedly connected to the right support plate 11. A workbench 2 is rotatably arranged symmetrically front and back between the two support plates 11. Second motors 12 are fixedly connected symmetrically front and back to the right support plate 11, and the output end of each second motor 12 is fixedly connected to a workbench 2. A synchronous docking mechanism 3 for aligning multiple lugs with the outside of the battery frame is arranged on the upper surface of each workbench 2. A longitudinal fixing mechanism 4 for fixing the frame is also arranged on the upper surface of each workbench 2. A receiving mechanism 10 for transporting the welded frame away is arranged at the rear parts of the two brackets 1.

[0034] It should be noted that in the above translation, the content in brackets [relevant figures] needs to be filled in according to the actual figures referred to in the original text. If there is no specific indication in the original text, it can be left blank or filled with appropriate descriptions according to the context.During specific operation, the upper surfaces of the two workbenches 2 are respectively fixed with the frame and the lifting lugs through the synchronous docking mechanism 3 and the longitudinal fixing mechanism 4. Then, the welding robot 14 is used to weld the frame and the lifting lugs on one of the workbenches 2. After the welding is completed, the support plate 11 is driven by the third motor 13 to rotate 180 degrees, so that the other un-welded workbench 2 rotates towards the direction close to the welding robot 14. At this time, the welded workbench 2 is driven by the second motor 12 to rotate, so that the welded workbench 2 drives the frame and the lifting lugs to be perpendicular downward. In this way, the synchronous docking mechanism 3 and the longitudinal fixing mechanism 4 release the fixation of the frame and the lifting lugs. After that, the welded frame and the lifting lugs fall from the flipped workbench 2 onto the material receiving mechanism 10, which solves the possibility of frame deformation caused by manual blanking. Then, the welded frame and the lifting lugs are transferred away by the material receiving mechanism 10. Finally, the workbench 2 that has unloaded the frame and the lifting lugs is driven by the second motor 12 to rotate again, so that the synchronous docking mechanism 3 and the longitudinal fixing mechanism 4 move upward to re-fix the frame and the lifting lugs that need to be welded on the workbench 2. At this time, when the welding of the other workbench 2 is completed, the support plate 11 is driven by the third motor 13 to rotate 180 degrees again, so that the other workbench 2 that has been re-fixed with the frame and the lifting lugs rotates towards the direction close to the welding robot 14, so that this workbench 2 drives the frame and the lifting lugs to be welded by the welding robot 14.

[0035] Refer to Figure 3 and Figure 6 As shown in FIGS. 7 and 8, the synchronous docking mechanism 3 includes moving plates 31 that are symmetrically slidably connected to the upper surface of the workbench 2 in the front and rear directions. A plurality of L-shaped supporting plates 33 are slidably connected to the top of each moving plate 31. An installation plate 34 is fixedly connected to the top of each supporting plate 33. A cylinder 35 is fixedly connected to the top of the installation plate 34. A pressing plate 36 is fixedly connected to the output end of the cylinder 35.

[0036] Refer to Figure 7 As shown in FIGS. 9 and 10, the synchronous docking mechanism 3 further includes a threaded rod 38 that is horizontally threadedly connected to one side of the bottom slideway of the supporting plate 33. The threaded rod 38 penetrates to one side of the bottom slideway of the supporting plate 33, and one end of the threaded rod 38 abuts against the moving plate 31. An extension rod 37 is fixedly connected to the end of the threaded rod 38 away from the supporting plate 33. A pull handle 39 is fixedly connected to the end of the extension rod 37 away from the threaded rod 38.

[0037] Refer to Figure 3 and Figure 4The workbench 2 is provided with two sets of notches 5 on the front and back sides. A connecting plate 32 is fixedly connected to the bottom of the movable plate 31. The connecting plate 32 extends through the notch 5 to the lower surface of the workbench 2. A cross plate 8 is fixedly connected between the two corresponding connecting plates 32 on the left and right. A sliding rod 7 is also fixedly connected to the lower surface of the workbench 2. The sliding rod 7 slides through the bottom of the corresponding front and rear connecting plates 32. The lower surface of the workbench 2 is rotatably connected to a bidirectional screw 6 through a connecting plate. The bidirectional screw 6 is threadedly connected to the cross plate 8, and both ends of the bidirectional screw 6 are fixedly connected to hand wheels 9.

[0038] During the specific work, when welding the lifting ears, multiple lifting ears are placed on the supporting plate 33, and the cylinder 35 is used to drive the pressure plate 36 to press the lifting ears down on the supporting plate 33. Then, the hand wheel 9 can be turned to drive the bidirectional screw 6 to rotate, and the bidirectional screw 6 drives the cross plate 8 to move to the outside of the battery frame. The cross plate 8 drives the movable plate 31 to move to the outside of the battery frame through the connecting plate 32. In this way, the movable plate 31 drives multiple lifting ears pressed down on the supporting plate 33 to approach and dock with the outside of the battery frame, and the docking of multiple lifting ears can be completed at one time, which greatly saves time and operation steps. The synchronous movement and docking can ensure that the positions of multiple lifting ears on the battery frame are relatively consistent, reducing the error of a single alignment.

[0039] When adjusting the spacing between multiple lifting ears, the pull handle 39 is rotated to drive the threaded rod 38 to rotate through the extension rod 37, so that the threaded rod 38 moves toward the outside of the supporting plate 33. At this time, the threaded rod 38 is disengaged from the interference with the movable plate 31, so that the supporting plate 33 can be pushed to move along the movable plate 31, so that the distance between the multiple lifting ears can be adjusted. After adjusting the distance, the pull handle 39 is rotated in the opposite direction. The pull handle 39 drives the threaded rod 38 to rotate synchronously in the opposite direction through the extension rod 37, and moves the threaded rod 38 toward the direction close to the movable plate 31, so that the threaded rod 38 is again in conflict with the side of the movable plate 31, which can fix the position of the supporting plate 33.

[0040] See also Figure 9 The material receiving mechanism 10 includes slide rails 101 symmetrically fixedly connected to the rear part of the bracket 1, and the tops of the two slide rails 101 are slidably connected to the material receiving plates 102 through rollers, and the left and right sides of the material receiving plates 102 are symmetrically fixedly connected to the connecting blocks 106.

[0041] The material receiving mechanism 10 also includes a driving wheel 103 which is symmetrically connected to the corresponding slide rail 101 for rotation. The two slide rails 101 are also symmetrically connected to the driven wheels 104 for rotation. The driving wheel 103 and the driven wheel 104 are connected for transmission via a transmission belt 105. The outside of the transmission belt 105 is fixedly connected to the end of the connecting block 106 away from the material receiving plate 102. A first motor 107 is fixedly connected to the side of the right slide rail 101. The output end of the first motor 107 is fixedly connected to the driving wheel 103. A transmission shaft 108 is fixedly connected between the two driving wheels 103.

[0042] During specific operation, after the welded frame and lugs are vertically downward, the first motor 107 drives the driving wheel 103 to rotate. The driving wheel 103 drives the conveyor belt 105 to rotate through the driven wheel 104. The rotating conveyor belt 105 drives the material receiving plate 102 to move on the slide rail 101 through the connecting block 106. When the material receiving plate 102 moves below the welded workbench 2, the welded frame and lugs fall off the workbench 2 and drop onto the material receiving plate 102. Then the first motor 107 rotates. Finally, the synchronous docking mechanism 3 and the longitudinal fixing mechanism 4 release the fixation of the frame and lugs, and drive the material receiving plate 102 to move out from below the workbench 2, so that the welded frame and lugs can be removed. When the material receiving plate 102 moves away from the support 1, at this time the material receiving plate 102 leaves below the workbench 2, so that the workbench 2 can rotate around the support 1.

[0043] Refer to Figure 3 and Figure 8 As shown in FIGS. and, the longitudinal fixing mechanism 4 includes first limit blocks 41 fixedly connected symmetrically before and after on the upper surface of the workbench 2. On the upper surface of the workbench 2 on both sides before and after the side of the first limit block 41, extrusion blocks 44 are rotatably connected symmetrically left and right. One end of the extrusion block 44 away from the first limit block 41 is fixedly connected with a rotating rod 43. Transverse fixing components 47 for preventing the frame from shifting are symmetrically arranged before and after on the upper surface of the workbench 2.

[0044] Refer to Figure 8 As shown in FIGS. and, the longitudinal fixing mechanism 4 further includes first triangular blocks 45. The first triangular blocks 45 are fixedly connected to the opposite surfaces of the corresponding rotating rods 43 before and after. Second triangular blocks 46 are fixedly connected to both end faces of the moving plate 31. The inclined surfaces of the second triangular blocks 46 are in mutual contact with the inclined surfaces of the first triangular blocks 45.

[0045] Refer to Figure 3 and Figure 5 As shown in FIGS. and, the transverse fixing components 47 include sleeves 471 fixedly connected to the connecting plate 32. A cavity 472 is opened at one end of the sleeve 471 away from the connecting plate 32. A slider 473 is slidably connected in the cavity 472 of the sleeve 471. A spring 474 is arranged inside the cavity 472. One end of the spring 474 is fixedly connected to the slider 473, and the other end of the spring 474 is fixedly connected to the sleeve 471. Second limit blocks 42 are symmetrically and fixedly connected to the upper surface of the workbench 2. The second limit blocks 42 are located in the direction away from the sleeve 471 of the slider 473.

[0046] During specific operation, when placing the battery frame on the upper surface of the workbench 2, the inner side of the frame is abutted and fitted against the sides of the first limit block 41 and the second limit block 42. When the moving plate 31 approaches the side of the frame, the moving plate 31 drives the second triangular block 46 to approach the side of the frame. At this time, the inclined surface of the second triangular block 46 pushes the inclined surface of the first triangular block 45, and the second triangular block 46 pushes the first triangular block 45 away from the battery frame. When the first triangular block 45 moves away from the battery frame, it drives the pressing block 44 to press the side of the battery frame through the rotating rod 43. The battery frame is fixed on both left and right sides by the pressing block 44 and the first limit block 41. When the connecting plate 32 drives the moving plate 31 to approach the battery frame in the front and rear directions, the sleeve 471 on the side of the connecting plate 32 drives the slider 473 to synchronously approach the battery frame in the front and rear directions. In this way, the slider 473 first abuts against the front and rear surfaces of the battery frame, and under the elastic force of the spring 474, the slider 473 is clamped on the side of the second limit block 42. The battery frame is fixed on both front and rear sides by the slider 473 and the second limit block 42.

[0047] Overall working process:

[0048] Fix the frame and the lifting lug on two workbenches 2 respectively through the docking mechanism 3 and the longitudinal fixing mechanism 4. Then, first weld the frame and the lifting lug on one workbench 2. After welding is completed, drive the support plate 11 to rotate 180 degrees by the third motor 13. The welded frame and lifting lug fall onto the receiving plate 102. The other workbench 2 with the frame and the lifting lug fixed rotates towards the direction close to the welding robot 14, so that this workbench 2 drives the frame and the lifting lug to be welded by the welding robot 14.
