Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a battery pack casing welding blanking device. Background Technology

[0002] During the production and processing of electric vehicle battery pack frames, multiple steel pipes need to be welded together to form a beam structure. Then, the beams are assembled and welded together to form the battery pack frame. During welding, both the top and bottom of the battery pack frame need to be welded, and the accuracy of the welding positions of each beam must be ensured to avoid errors. Therefore, welding robots are often used to weld the battery pack shell to improve the stability and accuracy of the welding. Currently, after the welding robot finishes welding the battery pack shell, the battery pack shell needs to be manually unloaded from the welding workbench. The battery pack shell is heavy, making it inconvenient for workers to operate and resulting in low work efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technology, which requires manual unloading of battery pack housings from the welding workbench, and which is inconvenient for workers to operate due to the weight of the battery pack housings and low work efficiency, this application provides a battery pack housing welding unloading device.

[0004] This application provides a battery pack casing welding and blanking device, which adopts the following technical solution:

[0005] A battery pack casing welding and blanking device includes two support bases, with a welding table rotatably disposed between the two support bases. Two parallel first support rails are mounted on the welding table, and multiple rollers are evenly rotatably disposed on each first support rail along its length. The rollers support the battery pack casing. A limiting component for fixing the battery pack casing is provided on the welding table, and a lifting component for raising and lowering the first support rails is provided at the bottom of the welding table. A support frame is mounted on one of the support bases, and two second support rails are mounted on the top of the support frame. The two second support rails are identical in shape and size to the first support rails. The support frame is positioned away from the welding table. An auxiliary frame is provided at one end of the support frame, and two third support rails are fixedly mounted on the auxiliary frame. The two third support rails are the same shape and size as the first support rail. A movable seat is provided on the top of the support frame and on one side of the second support rail. A sliding block is slidably mounted on the movable seat. A fourth support rail is mounted on the sliding block. The fourth support rail is the same shape and size as the first support rail. A fixing component for fixing the battery pack housing is also provided on the sliding block. A driving component for driving the sliding block to move along the length of the movable seat is provided on the support frame. An adjustment component for driving the two movable seats to move towards each other is provided on the support frame.

[0006] By adopting the above technical solution, during use, the battery pack housing is placed on the first support rail, and then fixed on the first support rail by the limiting component to facilitate welding by the welding robot. After the welding robot finishes welding the battery pack housing, the limiting component is first released from the restriction on the battery pack housing, and then the lifting component is used to lift the first support rail and the battery pack housing. When the first support rail is raised to the same height as the second support rail, the driving component drives the sliding block to move along the length of the moving seat. During the movement of the sliding block, the fourth support rail and the fixing component will move synchronously. When the fourth support rail moves to the bottom of the battery pack housing, the fixing component fixes the battery pack housing, and then the driving component moves in the opposite direction, thereby driving the fourth support rail and the battery pack housing to move synchronously to the third support rail on the auxiliary frame. When the battery pack housing moves to the appropriate position, the fixing component is released from the fixation on the battery pack housing, and then the driving component drives the sliding block to move back to the original position. The unloading process is simple and convenient, reduces labor intensity, and improves production efficiency.

[0007] Optionally, the fixing assembly includes a fixing seat, which is fixedly mounted on a sliding block. A pressing rod is rotatably mounted on the top of the fixing seat. One end of the pressing rod is used to press the battery pack housing, and the other end of the pressing rod is hinged to a first connecting rod. A driving seat is slidably mounted inside the fixing seat along the vertical direction. The end of the first connecting rod away from the pressing rod is hinged to the driving seat. A first lead screw is rotatably mounted on one side of the fixing seat along the vertical direction. The driving seat is threadedly connected to the first lead screw. A first drive motor is mounted at the bottom of the fixing seat. A connecting shaft is coaxially mounted on the output shaft of the first drive motor. The top of the connecting shaft is coaxially connected to the first lead screw.

[0008] By adopting the above technical solution, the fixing component can press and fix the battery pack housing on the fourth support rail, so that the driving component can drive the battery pack housing to move synchronously while moving the sliding block.

[0009] Optionally, the sliding block is provided with a mounting base, and a clamping block for clamping the battery pack housing is slidably disposed on the mounting base. A second lead screw is rotatably disposed inside the mounting base along its own length direction. The second lead screw is threadedly connected to the bottom of the clamping block. A driven bevel gear is coaxially disposed at one end of the second lead screw, and a driving bevel gear is coaxially disposed on the connecting shaft. The driving bevel gear meshes with the driven bevel gear.

[0010] By adopting the above technical solution, when the fixing component drives the pressing rod to press and fix the battery pack housing, the first drive motor will drive the second lead screw to rotate synchronously during the rotation of the first drive motor. During the rotation of the second lead screw, the clamping block will move towards the direction close to the battery pack housing, thereby clamping and fixing the battery pack housing, thus improving the fixing effect of the battery pack housing.

[0011] Optionally, the drive assembly includes a first rack disposed at the bottom of the sliding block, a first gear rotatably disposed inside the movable seat, the first gear meshing with the first rack, and a second drive motor disposed on the support frame, the output shaft of the second drive motor being connected to the first gear.

[0012] By adopting the above technical solution, when it is necessary to move the sliding block, the second drive motor is started. During the rotation of the second drive motor, the first gear will be driven to rotate. During the rotation of the first gear, the first rack will be driven to move along the length direction of the moving seat. The first rack is fixedly connected to the sliding block, thereby driving the sliding block to move synchronously.

[0013] Optionally, the adjustment assembly includes two adjustment seats, which are fixedly mounted on both sides of the top of the support frame. Each of the two movable seats has an adjustment block at its bottom, and the two adjustment blocks are slidably mounted on the two adjustment seats. A first adjustment rod is hinged to the bottom of one adjustment block, and a second adjustment rod is hinged to the other adjustment block. The first and second adjustment rods are hinged together, and a drive rod is hinged to the position where the first and second adjustment rods connect. A first cylinder is mounted on the top of the support frame, and the piston rod of the first cylinder is connected to the drive rod. A fixed shaft is coaxially mounted on the output shaft of the second drive motor. The fixed shaft is hollow, and a movable shaft is slidably mounted inside the fixed shaft along its length. The first gear is coaxially mounted on the movable shaft.

[0014] By adopting the above technical solution, the two fixed components can be moved toward each other or toward each other by adjusting the components, thereby enabling the fixing of battery pack housings of various sizes.

[0015] Optionally, the auxiliary frame is hinged to the support frame, a second cylinder is hinged to the top of the support frame, a rotating block is hinged to the bottom of the auxiliary frame away from the support frame, and the piston rod of the second cylinder is connected to the rotating block.

[0016] By adopting the above technical solution, when the battery pack housing is located on the auxiliary frame, the second cylinder is activated. The piston rod of the second cylinder will move towards the cylinder body, thereby causing the auxiliary frame to rotate at the position where it is hinged to the support frame. The auxiliary frame will move towards the support seat, at which time the auxiliary frame will tilt, so that the battery pack housing can be slowly lowered and placed on the moving tool used to move the battery pack housing, thus facilitating the battery pack housing to enter the next production process.

[0017] Optionally, the lifting assembly includes a lifting cylinder, which is disposed at the bottom of the welding table. A lifting frame is disposed at the bottom of the welding table along the vertical direction. The top of the lifting frame is connected to the bottom of the two first support rails, and the piston rod of the lifting cylinder is connected to the bottom of the lifting frame.

[0018] By adopting the above technical solution, after the welding robot finishes welding the battery pack housing, the lifting component raises the battery pack housing to the same height as the second support rail, so that the driving component can remove the battery pack housing from the welding table, thereby facilitating the unloading of the battery pack housing.

[0019] Optionally, the limiting component includes a limiting seat, which is disposed on the top of the welding table. A limiting rod is rotatably disposed on the limiting seat. The limiting rod is rotatably connected to the limiting seat via a rotating shaft. A second gear is coaxially disposed at one end of the rotating shaft. A second rack is slidably disposed on the welding table along the vertical direction. The bottom of the second rack is connected to the top of the lifting frame. The second rack meshes with the second gear.

[0020] By adopting the above technical solution, when the lifting assembly lifts the first support rail and the battery pack housing, the lifting cylinder can synchronously drive the second rack to move. During the movement of the second rack, the second gear will rotate, thereby causing the limit rod to move away from the battery pack housing, thus releasing the fixation of the battery pack housing, so as to facilitate the unloading of the battery pack housing.

[0021] Optionally, two L-shaped positioning rods are arranged parallel to each other at the end of the auxiliary frame away from the support frame.

[0022] By adopting the above technical solution, when the drive component moves the battery pack housing onto the auxiliary frame, the positioning rod will limit the movement position of the battery pack housing, preventing the battery pack housing from moving beyond the position of the auxiliary frame.

[0023] Optionally, the pressing rod is provided with a protective pad for protecting the surface of the battery pack housing.

[0024] By adopting the above technical solution, the protective pad can protect the surface of the battery pack housing, thereby avoiding, to some extent, the pressure rod from causing indentations on the surface of the battery pack housing when pressing and fixing it.

[0025] The present invention has the following advantages:

[0026] 1. By setting up lifting components, moving seats, sliding blocks, fixing components and driving components, it is possible to easily move the battery pack housing after welding to a position away from the welding table, thereby facilitating the unloading of the battery pack housing;

[0027] 2. By setting adjustment components, two fixed components can be moved closer to each other or further away from each other, thereby enabling the fixing of battery pack housings of various sizes;

[0028] 3. By setting a positioning rod, the positioning rod can limit the movement position of the battery pack housing and prevent the battery pack housing from moving beyond the position of the auxiliary frame. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0037] like Figures 1 to 6As shown, a battery pack housing welding and unloading device includes two support bases 1, with a welding table 11 rotatably mounted between the two support bases 1. Two parallel first support rails 12 are mounted on the welding table 11. Multiple rollers 13 are evenly rotatably mounted on each first support rail 12 along its length, supporting the battery pack housing 73. A limiting component for fixing the battery pack housing 73 is mounted on the welding table 11. A lifting component 3 for raising and lowering the first support rails 12 is mounted on the bottom of the welding table 11. A support frame 14 is provided on one of the support bases 1, with two second support rails 15 mounted on the top of the support frame 14. The two second support rails 15 are identical in shape and size to the first support rails 12. The support frame 14 is positioned away from the welding table. An auxiliary frame 16 is installed at one end of the support frame 11. Two third support rails 17 are fixedly installed on the auxiliary frame 16. The two third support rails 17 are the same shape and size as the first support rail 12. A movable seat 18 is installed on the top of the support frame 14 and on one side of the second support rail 15. A sliding block 181 is slidably installed on the movable seat 18. A fourth support rail 19 is installed on the sliding block 181. The fourth support rail 19 is the same shape and size as the first support rail 12. A fixing component 4 for fixing the battery pack housing 73 is also installed on the sliding block 181. A driving component 5 for driving the sliding block 181 to move along the length of the movable seat 18 is installed on the support frame 14. A component for driving the two movable seats 18 to move closer to each other is also installed on the support frame 14. The directional movement adjustment component 6; in use, the battery pack housing 73 is placed on the first support rail 12. Multiple rollers 13 on the first support rail 12 support the battery pack housing 73. Then, the limiting component fixes the battery pack housing 73 to the first support rail 12 to facilitate welding by the welding robot. After welding, the limiting component releases the restriction on the battery pack housing 73. Then, the lifting component 3 lifts the first support rail 12 and the battery pack housing 73. When the first support rail 12 is raised to the same height as the second support rail 15, the drive component 5 drives the sliding block 181 to move along the length of the moving seat 18. During the movement, the fourth support rail 19 and the fixing component 4 will move synchronously. When the fourth support rail 19 moves to the bottom of the battery pack housing 73, the fixing component 4 fixes the battery pack housing 73. Then, the drive component 5 moves in the opposite direction, thereby driving the fourth support rail 19 and the battery pack housing 73 to move synchronously to the third support rail 17 on the auxiliary frame 16. When the battery pack housing 73 moves to the appropriate position, the fixing component 4 releases the fixing of the battery pack housing 73. Then, the drive component 5 drives the sliding block 181 to move to the original position. The multiple rollers 13 on the first support rail 12, the second support rail 15 and the third support rail 17 can rotate freely, thereby facilitating the movement of the battery pack housing 73.

[0038] like Figures 1 to 6 As shown, the fixing assembly 4 includes a fixing base 41, which is fixedly mounted on the sliding block 181. A pressing rod 42 is rotatably mounted on the top of the fixing base 41. One end of the pressing rod 42 is used to press the battery pack housing 73, and the other end of the pressing rod 42 is hinged to a first connecting rod 43.

A first lead screw 45 is rotatably mounted on one side of the fixing base 41 along the vertical direction. The drive seat 44 is threadedly connected to the first lead screw 45. A first drive motor 46 is mounted on the bottom of the fixing base 41. A connecting shaft 47 is coaxially mounted on the output shaft of the first drive motor 46, and the top of the connecting shaft 47 is coaxially connected to the first lead screw 45. When it is necessary to fix the battery pack housing 73 to the fourth support... When the battery pack is on the support rail 19, the first drive motor 46 is started. During the rotation of the first drive motor 46, the connecting shaft 47 will rotate. During the rotation of the connecting shaft 47, the first lead screw 45 will rotate synchronously. During the rotation of the first lead screw 45, the drive seat 44 will move along the length of the first lead screw 45. During the movement of the drive seat 44, the first connecting rod 43 will move. During the movement of the first connecting rod 43, the pressing rod 42 will push one end away from the battery pack housing 73. The pressing rod 42 will rotate around the position connected to the fixed seat 41, so that the other end of the pressing rod 42 moves towards the battery pack housing 73. Thus, the pressing rod 42 presses the battery pack housing 73 onto the fourth support rail 19, thereby fixing the battery pack housing 73 so that it can be moved.

[0039] like Figures 1 to 6 As shown, a mounting base 48 is mounted on the sliding block 181, and a clamping block 481 for clamping the battery pack housing 73 is slidably mounted on the mounting base 48. A second lead screw 482 is rotatably mounted inside the mounting base 48 along its own length direction. The second lead screw 482 is threadedly connected to the bottom of the clamping block 481. A driven bevel gear 483 is coaxially mounted on one end of the second lead screw 482, and a driving bevel gear 484 is coaxially mounted on the connecting shaft 47. The driving bevel gear 484 meshes with the driven bevel gear 483. When the first drive motor... During the rotation of motor 46, the first drive motor 46 will drive the connecting shaft 47 to rotate synchronously. During the rotation of the connecting shaft 47, the active bevel gear 484 will rotate synchronously. During the rotation of the active bevel gear 484, the driven bevel gear 483 will rotate. During the rotation of the driven bevel gear 483, the second lead screw 482 will rotate synchronously. During the rotation of the second lead screw 482, the clamping block 481 will move towards the battery pack housing 73, thereby clamping and fixing the battery pack housing 73.

[0040] like Figures 1 to 6 As shown, the drive assembly 5 includes a first rack 51, which is mounted on the bottom of the sliding block 181. A first gear 52 is rotatably mounted inside the movable seat 18, and the first gear 52 meshes with the first rack 51. A second drive motor 53 is mounted on the support frame 14, and the output shaft of the second drive motor 53 is connected to the first gear 52. When it is necessary to move the sliding block 181, the second drive motor 53 is started. During the rotation of the second drive motor 53, the first gear 52 will be driven to rotate. During the rotation of the first gear 52, the first rack 51 will be driven to move along the length direction of the movable seat 18. The first rack 51 is fixedly connected to the sliding block 181, thereby driving the sliding block 181 to move synchronously.

[0041] like Figures 1 to 6 As shown, the adjustment assembly 6 includes two adjustment seats 61, which are fixedly installed on both sides of the top of the support frame 14. Adjustment blocks 62 are installed on the bottom of each of the two movable seats 18. The two adjustment blocks 62 are slidably installed on the two adjustment seats 61 respectively. A first adjustment rod 63 is hinged to the bottom of one adjustment block 62, and a second adjustment rod 64 is hinged to the other adjustment block 62. The first adjustment rod 63 and the second adjustment rod 64 are hinged together. A drive rod 65 is hinged to the position where the first adjustment rod 63 and the second adjustment rod 64 are connected. A first cylinder 66 is installed on the top of the support frame 14. The piston rod of the first cylinder 66 is connected to the drive rod 65. A fixed shaft 54 ​​is coaxially fixedly installed on the output shaft of the second drive motor 53. The fixed shaft 54 ​​is hollow. A movable shaft 55 is slidably installed inside the fixed shaft 54 ​​along its length. A fixed key is fixedly installed on the movable shaft 55 along its length, thereby allowing the movable shaft 55 to... When the fixed shaft 54 ​​can slide along its length, the fixed shaft 54 ​​can drive the movable shaft 55 to rotate synchronously. The first gear 52 is coaxially fixed on the movable shaft 55. The battery pack housing 73 has various sizes. In order for the fixing component 4 to fix the battery pack housing 73 of various sizes, the first cylinder 66 is activated. The piston rod of the first cylinder 66 will push the drive rod 65 to move synchronously. During the movement of the drive rod 65, the first adjusting rod 63 and the second adjusting rod 64 will move synchronously. During the movement of the first adjusting rod 63 and the second adjusting rod 64, the two adjusting blocks 62 will move towards each other or away from each other. During the movement of the two adjusting blocks 62, the two moving seats 18 will move synchronously, thereby causing the two fixing components 4 to move towards each other or away from each other, thus enabling the fixing of the battery pack housing 73 of various sizes.

[0042] like Figures 1 to 6As shown, the auxiliary frame 16 is hinged to the support frame 14. The top of the support frame 14 is hinged to a second cylinder 7, and the bottom of the auxiliary frame 16 away from the support frame 14 is hinged to a rotating block 71. The piston rod of the second cylinder 7 is connected to the rotating block 71. When the battery pack housing 73 is on the auxiliary frame 16, the second cylinder 7 is activated. The piston rod of the second cylinder 7 will move towards the cylinder body, thereby causing the auxiliary frame 16 to rotate at the position where it is hinged to the support frame 14. The auxiliary frame 16 will move towards the support base 1. At this time, the auxiliary frame 16 will tilt, which makes it easier for the battery pack housing 73 to slowly decrease in height and be placed on the moving tool used to move the battery pack housing 73, thus making it easier for the battery pack housing 73 to enter the next production process.

[0043] like Figures 1 to 6 As shown, the lifting assembly 3 includes a lifting cylinder 31, which is installed at the bottom of the welding table 11. A lifting frame 32 is installed vertically at the bottom of the welding table 11. The top of the lifting frame 32 is connected to the bottom of the two first support rails 12. The piston rod of the lifting cylinder 31 is connected to the bottom of the lifting frame 32. When in use, the lifting cylinder 31 is activated, and the piston rod of the lifting cylinder 31 moves away from the cylinder body. During the movement of the piston rod of the lifting cylinder 31, the lifting frame 32 will move synchronously. During the movement of the lifting frame 32, the first support rails 12 will move synchronously, thereby facilitating the lifting and lowering of the welded battery pack casing 73.

The bottom of the second rack 25 is connected to the top of the lifting frame 32, and the second rack 25 meshes with the second gear 24. When the lifting cylinder 31 pushes the lifting frame 32 to move, the lifting frame 32 will drive the second rack 25 to move synchronously. During the movement of the second rack 25, the second gear 24 will rotate synchronously. During the rotation of the second gear 24, the rotating shaft 23 will rotate. During the rotation of the rotating shaft 23, the limiting rod 22 will rotate synchronously. During the rotation of the limiting rod 22, it will move away from the battery pack housing 73, thereby releasing the fixation of the battery pack housing 73.

[0045] like Figures 1 to 6As shown, two L-shaped positioning rods 161 are installed parallel to each other on the auxiliary frame 16 at the end away from the support frame 14. When the drive assembly 5 moves the battery pack housing 73 onto the auxiliary frame 16, the positioning rods 161 will limit the movement position of the battery pack housing 73 to prevent the battery pack housing 73 from moving beyond the position of the auxiliary frame 16.

[0046] like Figures 1 to 6 As shown, a protective pad 72 is installed on the pressing rod 42 to protect the surface of the battery pack housing 73; the protective pad 72 can protect the surface of the battery pack housing 73, thereby avoiding, to some extent, the pressing rod 42 from causing indentations on the surface of the battery pack housing 73 when pressing and fixing the battery pack housing 73.

[0047] The implementation principle of this embodiment is as follows: In use, the battery pack housing 73 is placed on the first support rail 12, and then the battery pack housing 73 is fixed on the first support rail 12 by the limiting component to facilitate welding of the battery pack housing 73 by the welding robot. After the welding robot finishes welding the battery pack housing 73, the limiting component is first released from the restriction on the battery pack housing 73, and then the first support rail 12 and the battery pack housing 73 are lifted by the lifting component 3. When the first support rail 12 is raised to the same height as the second support rail 15, the sliding block is driven by the driving component 5. 181 moves along the length of the movable seat 18. During the movement of the sliding block 181, the fourth support rail 19 and the fixing component 4 will move synchronously. When the fourth support rail 19 moves to the bottom of the battery pack housing 73, the battery pack housing 73 is fixed by the fixing component 4. Then, the drive component 5 moves in the opposite direction, thereby driving the fourth support rail 19 and the battery pack housing 73 to move synchronously to the third support rail 17 on the auxiliary frame 16. When the battery pack housing 73 moves to the appropriate position, the fixing component 4 releases the fixing of the battery pack housing 73.
