Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to a battery cell module flipping device. Background Technology

[0002] Due to humanity's continuous pursuit of sustainable and clean energy, traditional fossil fuels can no longer meet people's needs. New energy batteries, as a clean energy source, possess advantages such as high efficiency, cleanliness, safety, and reliability, and have become a hot topic in energy development. With the rapid development of new energy vehicles, lithium battery packs are the most commonly used power modules, and the battery cell module is the most important component of the pack. During the assembly process, both the top and bottom surfaces of the battery cell module need to be fitted with accessories. Due to space limitations, both surfaces must be vertically upwards to complete the accessory installation; that is, the battery cell module needs to be rotated 180 degrees during assembly. Existing related equipment uses a cantilever structure (such as the Chinese utility model patent "A Battery Module Rotation Device", authorization announcement number CN216037215U) for rotation, resulting in uneven overall force distribution and limited rotational dimensions. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a battery cell module flipping device with an ingenious structural design. The flipping frame and the mounting bases at both ends have rotation fulcrums. Compared with the cantilever structure in the prior art, the flipping device has uniform force, low driving force, and energy saving.

[0004] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a battery cell module flipping device is provided, the flipping device includes a flipping frame, two mounting seats, a flipping drive mechanism, a long side clamping mechanism and a short side clamping mechanism, the two ends of the flipping frame are respectively rotatably connected to the two mounting seats, the power output end of the flipping drive mechanism is fixedly connected to one end of the flipping frame, and the flipping frame is driven to flip around the X-axis as the axis by the flipping drive mechanism;

[0005] The long-side clamping mechanism is installed on the long side of the flipping frame, and the short-side clamping mechanism is installed on the short side of the flipping frame. The long-side clamping mechanism clamps the battery cell module along the Y-axis, and the short-side clamping mechanism clamps the battery cell module along the Z-axis.

[0006] Furthermore, the short-side clamping mechanism includes a cylinder clamping mechanism, which includes a clamping cylinder, a first clamping seat, and a first clamping block. The first clamping block is mounted on the first clamping seat, and the power output end of the clamping cylinder is fixed to the first clamping seat. The two ends of the first clamping seat are slidably connected to the flipping frame through an X-axis slider rail structure.

[0007] Furthermore, the short-side clamping mechanism also includes a motor clamping mechanism, which includes a clamping motor, a first gear, a second gear, a lead screw, a second clamping seat, and a second clamping block. The first gear is installed at the power output end of the clamping motor. The lead screw passes through a nut fixed at the center of the second gear and the two are threaded together. One end of the lead screw is fixedly connected to the second clamping seat. The second clamping block is fixed on the second clamping seat. The first gear and the second gear mesh. Both ends of the second clamping seat are slidably connected to the flipping frame through an X-axis slider rail structure.

[0008] Furthermore, the flipping drive mechanism includes a flipping motor, a third gear, and a fourth gear. The third gear is mounted on the power output end of the flipping motor. The lead screw passes through the center of the fourth gear and is movable along the center of the fourth gear. The third gear and the fourth gear mesh. The fourth gear is fixed to one end of the flipping frame. The flipping motor is mounted on a mounting base.

[0009] Furthermore, the long-side clamping mechanism is installed on the two long sides of the flipping frame. Each long-side clamping mechanism includes a handwheel, a guide post, a screw, a base, a base, and a bottom-holding claw. One end of the screw is connected to the handwheel and is rotatably connected to the base via a thread, while the other end passes through the side of the flipping frame and is slidably connected to the base. One end of the guide post is fixedly connected to the base, and the other end passes through the side of the flipping frame and the base and is fixed with a bottom-holding claw. The guide post drives the screw to rotate by rotating the handwheel, which ultimately causes the bottom-holding claw to translate along the Y direction.

[0010] Furthermore, the mounting base is mounted on the frame and is driven to move up and down via a lifting drive mechanism;

[0011] A transfer carrier for placing battery cell modules is located directly below the flipping frame.

[0012] The beneficial effects of this utility model are:

[0013] When the flipping drive mechanism in this utility model drives the flipping frame to flip, there are rotation fulcrums between the flipping frame and the mounting seats at both ends. Compared with the cantilever structure in the prior art, the flipping device is subjected to uniform force, has low driving force, and is energy-saving.

[0014] The short-side clamping mechanism includes a cylinder clamping mechanism and a motor clamping mechanism. Because the position of the second clamping block of the motor clamping mechanism can be precisely controlled by the clamping motor, the second clamping block can be driven to any position. Therefore, it can be precisely positioned according to the position of the accessories to be installed on the battery cell module.

[0015] The long-side clamping mechanism can support the long side of the battery cell module, further ensuring the clamping effect on the battery cell mold and preventing the battery cell module from shaking during the flipping process or falling off due to accidental power or gas outages.

[0024] Battery cell module 10, frame 20, lifting drive mechanism 30, transfer carrier 40. Detailed Implementation

[0025] The following specific embodiments illustrate the detailed implementation of this utility model. Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0026] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0027] Example: A battery cell module flipping device, such as Figures 1 to 4 As shown, the flipping device includes a flipping frame 1, two mounting seats 2, a flipping drive mechanism 3, a long side clamping mechanism 4, and a short side clamping mechanism. The two ends of the flipping frame are rotatably connected to the two mounting seats respectively (bearings or other rotating parts can be installed at the rotatable connection to ensure smooth rotation). The power output end of the flipping drive mechanism is fixedly connected to one end of the flipping frame, and the flipping frame is driven to flip around the X-axis as the axis through the flipping drive mechanism.

[0028] The long-side clamping mechanism is installed on the long side of the flipping frame, and the short-side clamping mechanism is installed on the short side of the flipping frame. The long-side clamping mechanism clamps the battery cell module 10 along the Y-axis, and the short-side clamping mechanism clamps the battery cell module along the Z-axis.

[0029] In this embodiment, the short-side clamping mechanism includes a cylinder clamping mechanism 5, which includes a clamping cylinder 51, a first clamping seat 52, and a first clamping block 53. The first clamping block is mounted on the first clamping seat, and the power output end of the clamping cylinder is fixed to the first clamping seat. The two ends of the first clamping seat are slidably connected to the flipping frame through an X-axis slider rail structure.

[0030] In this embodiment, the short-side clamping mechanism further includes a motor clamping mechanism 6. The motor clamping mechanism includes a clamping motor 61, a first gear 62, a second gear 63, a lead screw 64, a second clamping seat 65, and a second clamping block 66. The first gear is mounted on the power output end of the clamping motor. The lead screw passes through a nut 67 fixed at the center of the second gear, and the two are threadedly connected. One end of the lead screw is fixedly connected to the second clamping seat. The second clamping block is fixed on the second clamping seat. The first gear and the second gear mesh. Both ends of the second clamping seat are slidably connected to the flipping frame via an X-axis slider rail structure. The rotation of the clamping motor drives the first gear to rotate, which in turn drives the second gear to rotate. Since a nut is fixed at the center of the second gear, and this nut is threadedly connected to the lead screw, the lead screw will translate along the X-axis, ultimately causing the second clamping block to translate along the X-axis.

[0031] In this embodiment, the flipping drive mechanism 3 includes a flipping motor 31, a third gear 32, and a fourth gear 33. The third gear is mounted on the power output end of the flipping motor. The lead screw passes through the center of the fourth gear and can move along the center of the fourth gear. The third gear and the fourth gear mesh. The fourth gear is fixed to one end of the flipping frame. The flipping motor is mounted on a mounting base. The rotation of the flipping motor drives the third gear to rotate, which in turn drives the fourth gear to rotate. Since the fourth gear is fixed to the flipping frame, it will cause the flipping frame to rotate 180 degrees. Because the lead screw passes through the center of the fourth gear and is slidably connected to it, the flipping drive mechanism and the short-side clamping mechanism do not interfere with each other, and each can achieve its own function and purpose.

[0032] In this embodiment, the long-side clamping mechanism is installed on the two long sides of the flipping frame. Each long-side clamping mechanism 4 includes a handwheel 41, a guide post 42, a screw 43, a base 44, a base 45, and a bottom-claw 46. One end of the screw is connected to the handwheel and is rotatably connected to the base via a thread, while the other end passes through the side of the flipping frame and is slidably connected to the base. One end of the guide post is fixedly connected to the base, and the other end passes through the side of the flipping frame and the base, and is fixed with a bottom-claw. The guide post drives the screw to rotate by rotating the handwheel, ultimately causing the bottom-claw to translate along the Y direction. Rotating the handwheel causes the screw to rotate. Since the screw is rotatably connected to the base via a thread, and the other end of the screw is slidably connected to the base, the base and the guide post will translate, ultimately causing the bottom-claw to translate.

[0033] In this embodiment, as Figure 5 As shown, the mounting base is mounted on the frame 20 and is driven to rise and fall 30 by a lifting drive mechanism. There are many types of lifting drive mechanisms, such as a servo motor combined with a sprocket and chain structure, which is existing technology and will not be described in detail.

[0034] A transfer carrier 40 for placing battery cell modules is located directly below the flipping frame.

[0035] The working principle and process of this utility model:

[0036] The battery cell module 10 arrives at the work position via a transfer carrier, with its A-side facing upwards. After the relevant components are installed, the flipping device (at this time, both the long-side clamping mechanism and the short-side clamping mechanism are in the open state) descends to a designated height under the action of the lifting drive mechanism (e.g., controlled by photoelectric sensors). The long-side clamping mechanism, the cylinder clamping mechanism, and the motor clamping mechanism all close, putting the battery cell module in a clamped state. Then, under the action of the lifting drive mechanism, the battery cell module rises to a designated height (e.g., controlled by photoelectric sensors). At this time, the flipping drive mechanism drives the flipping frame to rotate 180 degrees, causing the battery cell module to flip 180 degrees so that its B-side faces upwards. Then, under the action of the lifting drive mechanism, the battery cell module descends again to a designated height (e.g., controlled by photoelectric sensors), and then the relevant accessories are installed manually.

Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
