Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery packing technology, specifically to a multi-stage telescopic clamping structure and a battery packing device. Background Technology
[0002] During battery assembly, the batteries first undergo a voltage testing process, typically using specialized battery voltage testing equipment. This equipment precisely measures the voltage of each battery to ensure accurate voltage data. For example, a high-precision voltmeter is used to read and display the battery voltage value in real time by contacting the positive and negative terminals. After voltage testing, the batteries are conveyed to shelves via a transport device. This device, generally composed of conveyor belts and rollers, smoothly and quickly transports the batteries from the voltage testing location to the shelf area. The shelves usually have a specific storage structure and layout, divided into sections based on battery type and specifications for easy retrieval. Batteries are placed on the shelves in a specific order and according to certain rules, such as arranged by voltage or categorized by production batch, facilitating the accurate retrieval of batteries with the same voltage.
[0003] When battery pairing is required, a specialized gripping device, following instructions from the control system, retrieves batteries of the same voltage from the shelf. Multiple batteries of the same voltage are then transported via a conveyor to a storage area for buffering. During transport, it is crucial to ensure the batteries are moved smoothly to prevent damage or voltage fluctuations caused by collisions or other factors.
[0004] A common gripping device is the articulated robotic arm, which consists of multiple jointed links, similar in structure to a human arm. It has multiple degrees of freedom, allowing for flexible movement in space and adapting to battery gripping needs at different positions and angles. However, it has certain drawbacks: due to its movement method and structural characteristics, an articulated robotic arm requires a certain amount of time to control the movement of each joint, including extension and rotation, to complete each gripping action. Its individual gripping cycle is relatively long, which may affect overall production efficiency on production lines that require a large number of battery packs. Utility Model Content

[0017] Furthermore, the horizontal guide plate has U-shaped grooves with lateral openings on both sides, and the base has upright plates corresponding to the two U-shaped grooves. Each upright plate has a guide member that cooperates with the U-shaped grooves.
[0018] Furthermore, the guide component comprises multiple rollers rotatably mounted on the vertical plate. These rollers are arranged along the length of the vertical plate, and the outer diameter of each roller is adapted to the width of the U-shaped groove.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. 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.
[0039] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0040] An embodiment of the multi-stage telescopic clamping structure provided by this utility model:
[0041] like Figure 1 As shown, a multi-stage telescopic gripping structure includes a vertical guide frame and a gripping assembly. The vertical guide frame is arranged on the side of the shelf and is a column (not shown in the figure). The gripping assembly includes a mounting frame 1, which is slidably mounted on the vertical guide frame. The vertical guide frame is used to adjust the vertical position of the gripping assembly. The gripping assembly also includes two horizontal guide plates 2 arranged on the mounting frame 1. Each horizontal guide plate 2 has a base 3 slidably mounted on it. Each base 3 has a gripper 4 for gripping a battery on its lower side. Each base 3 has a retracting position that retracts to the lower side of the horizontal guide plate 2 and a working position that extends to the outside of the horizontal guide plate 2. The gripping assembly also includes a drive structure for driving each base 3 to move horizontally along the horizontal guide plate 2.
[0042] It should be noted that, for ease of explanation, Figure 1 The diagram only shows the structure and arrangement of one horizontal guide plate 2; the structure and arrangement of the other horizontal guide plate 2 are exactly the same as this horizontal guide plate 2.
[0043] In this embodiment, the two horizontal guide plates 2 are collinear in the horizontal direction, and are used to simultaneously extend or retract from the mounting bracket 1 to simultaneously clamp two batteries.
[0044] like Figure 1 As shown, the driving structure consists of two drive motors 5 arranged on the mounting frame 1, each corresponding to one of the two horizontal guide plates 2. The output end of each drive motor 5 is connected to a first gear, which meshes with a second gear. The horizontal guide plate 2 has a rack 6 that meshes with the second gear. The drive motors 5 are used to drive the horizontal guide plates 2 to move through gear transmission and rack transmission.
[0045] Specifically, the output shaft of the drive motor 5 is rotatably mounted on the mounting bracket 1, and the second gear is also rotatably mounted on the mounting bracket 1.
[0046] In this embodiment, the rack 6 is located in the middle of the horizontal guide plate 2. In other embodiments, the rack may also be located in a position other than the middle of the horizontal guide plate 2.
[0047] In this embodiment, each horizontal guide plate 2 has a direct-acting cylinder (not shown in the figure) at its bottom for reciprocating movement of the base 3, and the output end of the direct-acting cylinder is connected to the base 3. In other embodiments, the direct-acting cylinder can be replaced by a servo electric cylinder.
[0048] Regarding the guidance of the horizontal guide plate 2 and the base 3: The horizontal guide plate 2 has U-shaped grooves 7 with lateral openings on both sides. The base 3 has upright plates 8 corresponding to the two U-shaped grooves 7. Each upright plate 8 has a guide component that cooperates with the U-shaped groove 7.
[0049] Specifically, the guide components are multiple rollers 9 rotatably mounted on the vertical plate 8. The multiple rollers 9 are arranged along the length of the vertical plate 8, and the outer diameter of each roller 9 is adapted to the width of the U-shaped groove 7. By using multiple rollers 9 in conjunction with the U-shaped groove 7, the stability of the horizontal guide plate 2 during movement is improved.
[0050] Finally, in order to reduce costs, multiple weight-reducing holes 10 are also provided on the base 3.
[0051] The working principle of the multi-stage telescopic clamping structure provided by this utility model is as follows: When clamping the battery, the up-and-down moving mounting bracket 1 can adjust the up-and-down position of the clamping component, thereby adjusting the clamping component to the clamping position and the transfer position. The horizontal guide plate 2 and the base 3 of the clamping component can reciprocate, realizing multi-stage telescopic movement, increasing the extension length of the gripper 4, expanding the clamping range, and at the same time, the two horizontal guide plates 2 can clamp two batteries at the same time, shortening the gripping cycle and improving the battery matching efficiency.
[0052] An embodiment of the battery matching device provided by this utility model:
[0053] A battery pairing device includes a shelf, a multi-stage telescopic clamping structure, and a buffer area for placing the paired batteries. The multi-stage telescopic clamping structure is exactly the same as the multi-stage telescopic clamping structure in the above embodiment, and will not be described again here.
