Description

Technical Field

[0001] This utility model relates to the field of battery frame assembly technology, specifically to an assembly mechanism for an external battery frame structure. Background Technology

[0002] The power battery is one of the core components of pure electric vehicles or hybrid electric vehicles, and its operational safety and weight directly affect the reliability and performance of the entire vehicle. Currently, the weight of a power battery pack mainly includes the weight of the individual battery cells and the frame, generally weighing around 400-600 kg, of which the non-battery parts account for about 170 kg. This increases the overall weight of the vehicle, making it more difficult to reduce fuel consumption and emissions.

[0003] Steel components used for battery mounting are relatively heavy. Magnesium alloys, on the other hand, have low density, low vibration damping, and excellent thermal conductivity. Battery frames made of magnesium alloys are lightweight, have good damping and shock absorption, and good thermal and electrical conductivity. Battery frame production typically involves first preparing the frame sheet structure and then assembling the sheets, which requires an assembly machine. Traditional assembly machines require manual handling of the sheets. Therefore, we provide an automated sheet-picking assembly mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an assembly mechanism for an external battery frame structure, which solves the problem of manually picking up and assembling sheet metal as mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembly mechanism for an external battery frame structure, including an assembly platform, a support frame fixedly mounted on the top of the assembly platform, a linear motor fixedly mounted on the top of the support frame, and a frame material handling mechanism fixedly mounted on the moving end of the linear motor, further comprising:

[0006] The upper unloading mechanism includes a slide rail fixedly connected to the top of the assembly table, a slide table slidably mounted on the top of the slide rail, a drive motor fixedly mounted on one end of the slide rail, a pulley set fixedly mounted on the output end of the drive motor, a lead screw being driven and connected to the drive motor through the pulley set, and the lead screw being connected to the slide table through a lead screw sleeve.

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: an assembly mechanism for an external battery frame structure, including an assembly platform 1, a support frame 2 fixedly mounted on the top of the assembly platform 1, a linear motor 3 fixedly mounted on the top of the support frame 2, and a frame material handling mechanism 4 fixedly mounted on the moving end of the linear motor 3, and further including:

[0024] The upper unloading mechanism 5 includes a slide rail 51 fixedly connected to the top of the assembly table 1. A slide table 52 is slidably mounted on the top of the slide rail 51. A drive motor 53 is fixedly mounted on one end of the slide rail 51. A pulley set 54 is fixedly mounted on the output end of the drive motor 53. The drive motor 53 is connected to a lead screw 55 through the pulley set 54. The lead screw 55 is connected to the slide table 52 through a lead screw sleeve. Since the slide table 52 is restricted by the rotation of the slide rail 51, when the lead screw 55 rotates, it can only drive the slide table 52 to slide horizontally.

[0025] The unloading mechanism 5 also includes a column 56 fixedly connected to the top of the slide table 52. The column 56 is rotatably connected to a frame bracket 57. The frame bracket 57 is connected to the slide table 52 through a telescopic air rod 58. The telescopic air rod 58 can drive the frame bracket 57 to rotate.

[0026] As a preferred embodiment, based on the above method, the pulley assembly 54 further includes a first pulley 541 fixedly connected to the output end of the drive motor 53, a conveyor belt 542 fitted on the outer wall of the first pulley 541, a second pulley 543 fitted on one end of the conveyor belt 542, and the second pulley 543 fixedly connected to one end of the lead screw 55.

[0027] Specifically, the lead screw 55 is rotatably connected to the slide rail 51 via a bearing. The rotation of the drive motor 53 drives the first pulley 541 to rotate, which in turn drives the second pulley 543 and the lead screw 55 to rotate via the conveyor belt 542.

[0028] The frame bracket 57 includes a support frame 571 rotatably connected to the top of the column 56. A horizontal electric push rod 572 is fixedly connected to the side wall of the support frame 571. A vertical electric push rod 573 is fixedly connected to the output end of the horizontal electric push rod 572. A clamping plate 574 is fixedly connected to the top end of the vertical electric push rod 573.

[0029] Specifically, the horizontal electric push rod 572 can drive the vertical electric push rod 573 to move, thus facilitating the support of different frame materials. When the vertical electric push rod 573 extends or retracts, it can drive the clamp 574 to fix the frame material on the support frame 571.

[0030] The inner wall of the support frame 571 has a groove for placing the frame plate, and the clamping plate 574 can clamp and fix the frame plate placed in the groove.

[0031] The telescopic air rod 58 has two ends that are rotatably connected to the support frame 571 and the slide table 52, respectively. The rotatable connection between the two ends of the telescopic air rod 58 allows for angle adjustment when the telescopic air rod 58 extends or retracts.

[0032] As a preferred embodiment, based on the above method, the frame material handling mechanism 4 further includes a first slide 41 fixedly connected to the moving end of the linear motor 3, a spacing electric push rod 42 fixedly connected to the inner side wall of the first slide 41, a second slide 43 fixedly connected to the output end of the spacing electric push rod 42, and the second slide 43 slidably connected to the linear motor 3. The spacing electric push rod 42 can be extended or retracted to adjust the spacing between the first slide 41 and the second slide 43.

[0033] Two lifting air rods 44 are respectively installed on the side walls of the first slide 41 and the second slide 43. The output end of the lifting air rod 44 is fixedly connected to the second clamp 45. The side wall of the second clamp 45 is provided with an anti-fall-off component.

[0034] Specifically, the extension and retraction of the lifting air rod 44 can drive the clamping plate 45 to move up and down, which, together with the spacing electric push rod, completes the purpose of clamping and transportation.

[0035] The anti-fall-off component includes an extension plate 46 fixedly connected to the clamp plate 45, a pusher rod 47 fixedly connected to the side wall of the extension plate 46, a pusher plate 48 fixedly connected to the output end of the pusher rod 47, a pull rod 49 slidably connected to one end of the pusher plate 48, and an anti-fall-off buckle 410 rotatably connected to one end of the pull rod 49.

[0036] The push plate 48 has a movable groove, and the pull rod 49 can slide horizontally in the movable groove. The anti-drop buckle 410 is rotatably connected to the extension plate 46. The extension and retraction of the push rod 47 can drive the push plate 48 to move, thereby driving the anti-drop buckle 410 to fasten the frame material through the pull rod 49, thus completing the fixation of the frame material.

[0037] In summary, the assembly mechanism of this battery external frame structure, when in use, places the plate in the groove on the support frame 571, and the vertical electric push rod 573 drives the clamping plate 574 to move, clamping and fixing the frame. The drive motor 53 drives the lead screw 55 to rotate, which moves the slide table 52 to complete the transport of the frame. At the same time, the telescopic air rod 58 can extend and retract, which can also drive the support frame 571 to flip and assemble the side frame. During assembly, the plate can also be moved by the frame material handling mechanism 4. When movement is required, the spacing electric push rod 42 can adjust the distance between the two clamping plates 45. The two clamping plates 45 cooperate with each other to clamp the frame. At the same time, when vertical movement is required, the lifting air rod 44 can extend and retract to move vertically. During handling, the push air rod 47 extends and can also drive the push plate 48 to move. The push plate 48 controls the anti-drop buckle 410 to flip and fasten the frame, completing the effective fixing and handling of the frame.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
