Description

Technical Field

[0001] This utility model relates to the field of battery production and packaging equipment technology, specifically to a delayed clamping fixture for square battery cell modules. Background Technology

[0002] In the battery pack manufacturing industry, the series and parallel assembly of square cell modules requires clamping and fixing with fixtures before laser welding and other operations. In existing technologies, traditional cell module clamping fixtures mostly use fixed-position cylinders for clamping. However, when dealing with cell modules of different sizes or lengths, cylinder position adjustment has significant drawbacks: the adjustment method usually relies on manual disassembly and reassembly or manual screw fine-tuning, requiring repeated adjustments with tools, which is time-consuming, labor-intensive, and difficult to guarantee accuracy, easily leading to uneven clamping of cell modules and affecting welding quality. At the same time, the fixed structure of the cylinder cannot quickly adapt to diverse cell module specifications, requiring frequent fixture changes or large-scale equipment modifications when producing different models, resulting in high costs and low efficiency. Furthermore, the lack of integrated guiding and locking mechanisms leads to unstable cylinder movement trajectories, numerous manual intervention steps, and difficulty in integrating into automated production lines. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a delayed clamping fixture for square battery cell modules, aiming to solve the problems that existing adjustment methods usually rely on manual disassembly and reassembly or manual screw fine adjustment, and that the fixed structure of the cylinder cannot quickly adapt to diverse battery cell module specifications.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a square battery cell module delay clamping fixture, comprising: a base, a first baffle perpendicular to the battery cell stacking direction and a second baffle parallel to the battery cell stacking direction disposed on the base, a guide structure parallel to the battery cell stacking direction disposed on the base, a delay cylinder slidably disposed on the guide structure, a push plate disposed at the output end of the delay cylinder, the guide structure restricting the movement trajectory of the delay cylinder so that the delay cylinder can only move in the horizontal direction, and a locking structure disposed between the guide structure and the delay cylinder, the locking structure enabling the delay cylinder to be locked from point A on the guide structure to point B on the guide structure.

[0005] Furthermore, the guide structure is a T-shaped slide rail, and the delay cylinder is slidably connected to the T-shaped slide rail.

[0006] Furthermore, the feature is that a mounting base is slidably disposed on the guide structure, and the delay cylinder is fixedly disposed on the mounting base.

[0007] Furthermore, the locking structure includes a lever slidably disposed on the mounting base, a plurality of slots distributed along the moving path of the mounting base and corresponding to the lever, the sliding direction of the lever being perpendicular to the moving direction of the mounting base, and a pull rod that drives the lever to disengage from the slots when unlocking, the pull rod being slidably disposed on the mounting base.

[0008] Furthermore, the lever has a contact surface that contacts the pull rod, and the pull rod has a guide ramp. When unlocking, the guide ramp presses against the contact surface, causing the lever to move and disengage from the slot.

[0009] Furthermore, the pull rod also has a fixing part, and the guide slope and the fixing part contact the clamp rod in sequence. The fixing part has a plane parallel to the clamp rod. When the clamp rod is disengaged from the slot, the pull rod is pulled further. The movement of the pull rod causes the fixing part to contact the clamp rod. The fixing part is squeezed by the pull rod, thereby causing the mounting base to move.

[0010] Furthermore, the locking structure has two sets, which are distributed on both sides of the mounting base.

[0011] Furthermore, a connecting rod connects the two sets of locking structure rods.

[0012] Furthermore, it also includes a controller and a solenoid valve. An external air source is connected to the delay cylinder through the solenoid valve, and the controller is electrically connected to the solenoid valve.

[0013] The present invention describes a delayed clamping fixture for square battery cell modules. Its advantages are as follows: by setting a guide structure and a locking structure parallel to the battery cell stacking direction, the delayed cylinder can move flexibly in the horizontal direction and be precisely locked in different positions. This design allows for quick adjustment of the cylinder position without complicated disassembly. It can not only effectively improve the versatility of the fixture for battery cell modules of different lengths, but also ensure the movement accuracy through the trajectory limitation of the guide structure and achieve reliable position fixation through the locking structure. This significantly improves the adjustment efficiency and clamping stability, and solves the technical problems of inconvenient cylinder position adjustment and poor production adaptability in the prior art.

[0018] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0019] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] To further illustrate the principle and structure of this utility model, the preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figure 1-3As shown, this utility model embodiment provides a delayed clamping fixture for a square battery cell module, including: a base 1, a first baffle 11, a second baffle 12, a guide structure, a delayed cylinder 15, and a locking structure. The base 1 serves as a basic support component. The first baffle 11 is disposed on the base 1 and perpendicular to the battery cell stacking direction, used to limit the end position of the battery cell module. The second baffle 12 is parallel to the battery cell stacking direction, assisting in the side positioning of the battery cell module. The guide structure is disposed on the base 1 parallel to the battery cell stacking direction, its function being to restrict the movement trajectory of the delayed cylinder 15, allowing the delayed cylinder 15 to move only in the horizontal direction. The delayed cylinder 15 is slidably disposed on the guide structure, and a push plate is provided at the output end of the delayed cylinder 15, which is driven by an external air source to achieve the clamping action of the battery cell module. The locking structure between the guide structure and the delayed cylinder 15 can accurately lock the delayed cylinder 15 from its initial position (point A) on the guide structure to the target position (point B), adapting to the clamping requirements of battery cell modules of different lengths.

[0022] Furthermore, the aforementioned fixture integrates automated control components, including a controller and a solenoid valve. An external air source (such as an air compressor) is connected to the delay cylinder 15 via the solenoid valve, and the controller is electrically connected to the solenoid valve. The opening and closing time of the solenoid valve can be controlled through a preset program, thereby adjusting the clamping duration of the delay cylinder 15. When it is necessary to clamp the battery cell module, the operator sets the delay parameter through the controller. After the solenoid valve opens, the air source drives the delay cylinder 15 to move along the guide structure and clamp the module. After the preset time is reached, the cylinder automatically holds or resets. This design, through the linkage of the mechanical structure and the control system, realizes the automated adjustment and precise control of the battery cell module clamping process, significantly improving production efficiency and reducing the intensity of manual operation.

[0023] Furthermore, the aforementioned guide structure is specifically a T-shaped slide rail 13. The structural design of the T-shaped slide rail 13 forms a suitable guiding fit with the sliding connection part of the delay cylinder 15. The delay cylinder 15 engages with the track groove of the T-shaped slide rail 13 through its bottom sliding component, allowing the delay cylinder 15 to slide stably in the horizontal direction on the T-shaped slide rail 13. At the same time, the limiting structure of the T-shaped slide rail 13 can effectively prevent the delay cylinder 15 from lateral displacement during movement, ensuring the accuracy and stability of its movement trajectory and providing a reliable foundation for subsequent precise locking.

[0024] A mounting base 14 is slidably mounted on the guide structure (T-shaped slide rail 13), and the aforementioned delay cylinder 15 is fixed to the mounting base 14 by bolts, clips, or other means. The mounting base 14 serves as the connecting carrier between the delay cylinder 15 and the guide structure, and its bottom is provided with a sliding groove that matches the T-shaped slide rail 13, allowing it to slide freely on the guide structure. By fixing the delay cylinder 15 to the mounting base 14, the position adjustment of the delay cylinder 15 is transformed into the position movement of the mounting base 14 on the guide structure. This not only facilitates the quick disassembly and maintenance of the delay cylinder 15, but also allows for flexible changes in the position of the delay cylinder 15 in the cell stacking direction through the sliding adjustment of the mounting base 14. Combined with the locking structure, this enables adaptive clamping of cell modules of different specifications.

[0025] Furthermore, the aforementioned locking structure includes a locking rod 2 slidably disposed on the mounting base 14, a plurality of locking slots 3 distributed along the moving path of the mounting base 14, and a pull rod 4 slidably disposed on the mounting base 14. The sliding direction of the locking rod 2 is perpendicular to the moving direction of the mounting base 14. The locking slots 3 are correspondingly disposed to the locking rod 2. When the locking rod 2 is inserted into the locking slot 3, the mounting base 14 can be locked at the target position (such as point A or point B) of the guide structure. When unlocking, pulling the pull rod 4 causes the locking rod 2 to disengage from the locking slot 3, allowing the mounting base 14 to slide freely along the guide structure.

[0026] Furthermore, the aforementioned locking rod 2 has a contact surface that contacts the pull rod 4, and the pull rod 4 is correspondingly provided with a guide slope 41. During the unlocking operation, the pull rod 4 is pulled in a preset direction, and the guide slope 41 gradually contacts the contact surface of the locking rod 2 and generates a squeezing effect. This squeezing force pushes the locking rod 2 to slide in a direction perpendicular to the movement of the mounting base 14 until the locking rod 2 is completely disengaged from the locking groove 3, releasing the locking state between the mounting base 14 and the guide structure. At this time, the mounting base 14 can freely adjust its position on the guide structure.

[0027] Furthermore, the pull rod 4 is also provided with a fixing part 42, which is distributed sequentially with the guide slope 41 along the moving path of the pull rod 4. When the locking rod 2 disengages from the slot 3 under the action of the guide slope 41, the pull rod 4 is pulled further, and the fixing part 42 of the pull rod 4 contacts the locking rod 2. Since the fixing part 42 has a plane parallel to the locking rod 2, when the pull rod 4 is pulled, the fixing part 42 squeezes the locking rod 2 through this plane, thereby driving the mounting base 14 to move along the guide structure, realizing the adjustment of the position of the delay cylinder 15 until it moves to the target position (such as point B), after which the pull rod 4 is released and reset. After the locking rod 2 disengages from the contact of the guide slope 41, it slides downward into the lower slot 3 by its own gravity, thereby completing the position adjustment.

[0028] Furthermore, two sets of locking structures are provided, symmetrically distributed on both sides of the mounting base 14. This symmetrical design ensures that the mounting base 14 is subjected to uniform force during locking, avoiding tilting or displacement deviation caused by locking on one side, thereby improving the stability and accuracy of the position locking of the delay cylinder 15. It is suitable for assembling square battery cell modules where high clamping accuracy is required.

[0029] Furthermore, a connecting rod 43 connects the two sets of locking structure pull rods 4. Through the linkage design of the connecting rod 43, the operator only needs to operate one side of the pull rod 4 to drive the other side of the pull rod 4 to move synchronously, causing the two sets of locking rods 2 to simultaneously disengage from or lock into the slots 3. This structure simplifies the operation process, avoids the asynchrony problems that may occur when operating independently on both sides, and further improves the efficiency and reliability of adjusting the position of the mounting base 14.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
