Description

Technical Field

[0001] This utility model relates to the technical field of battery testing equipment, and in particular to an adaptive battery clamping testing cabinet. Background Technology

[0002] As a core component of modern electronic devices and new energy systems, battery performance testing is of paramount importance in both production and use. Currently, the most common battery types on the market are cylindrical and prismatic batteries, which differ significantly in shape, size, and electrode structure. However, existing battery testing equipment typically only accommodates a single battery type for clamping and testing, failing to simultaneously meet the testing requirements for both cylindrical and prismatic batteries. This limitation necessitates the use of multiple testing devices in practical applications, increasing costs and reducing testing efficiency. Furthermore, existing testing equipment also suffers from shortcomings in clamping stability, ease of operation, and testing accuracy, particularly when dealing with batteries of different sizes and specifications, making flexible adjustment and adaptive clamping difficult. Therefore, developing a testing device compatible with multiple battery types and possessing efficient, stable, and accurate testing capabilities has become an urgent problem to solve. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive battery clamping and testing cabinet to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An adaptive battery clamping and testing cabinet includes a frame, a limiting clamping assembly, testing modules, and a lifting mechanism. The frame serves as the supporting framework for the overall equipment, used to install and fix the various functional components. The limiting clamping assembly is externally mounted on one side, and multiple testing modules are vertically arranged inside. Furthermore, the limiting clamping assembly and the testing modules are electrically connected to achieve data transmission, thereby supporting different types of battery testing tasks.

[0005] The limiting clamping assembly includes a base plate, a positioning plate, a movable plate, a slatted bar, an adjusting component, and a connector. The base plate has a sliding structure to support the horizontal movement of the movable plate, and rectangular adjusting grooves on both sides to guide the sliding of the movable plate. Specifically, the positioning plate is fixed to one side of the base plate, forming a clamping structure with the movable plate. Both have elongated elliptical fixing grooves, within which the connector is installed and locked in place by fasteners. The slatted bar is located between the movable plate and the positioning plate, and has downward-extending V-shaped grooves that gradually narrow from top to bottom, forming an adaptive support structure for stably supporting batteries of different diameters. Furthermore, the surface of the V-shaped grooves undergoes special treatment to reduce the coefficient of friction, ensuring that the batteries are not damaged during clamping.

[0006] The adjustment assembly includes a fixed sheet metal, a double-ended positioning block, a handle, a connecting rod, a sleeve, and a guide rod. The fixed sheet metal is fixedly connected to the base plate by screws and nuts. The double-ended positioning block has a sleeve and a handle at each end. The handle is rotatably connected to the double-ended positioning block. One end of the connecting rod is hinged to the handle, and the other end is rotatably connected to the guide rod. The guide rod passes through the sleeve and is slidably connected to the sleeve, with its end fixedly connected to the movable plate. Rotating the handle drives the connecting rod to slide the guide rod horizontally, thereby controlling the horizontal movement of the movable plate and adapting it to batteries of different lengths.

[0007] The testing module includes a battery testing box, an electrode positioning plate, a clamping cross plate, and a finger cylinder. The battery testing box is fixedly connected to the frame, and the electrode positioning plate is located below it. Multiple horizontally arranged connecting electrodes are fixed on the electrode positioning plate for contacting the positive and negative tabs on the top of the square battery to achieve electrical connection. Further, the clamping cross plate is located below the electrode positioning plate and slides along it, clamping the battery under the control of the finger cylinder. The clamping cross plate is slidably connected to the frame and moves up and down via a lifting mechanism to ensure accurate contact between the square battery and the electrodes on the electrode positioning plate.

[0008] The lifting mechanism includes a lifting slide plate, connecting sheet metal, and a lifting cylinder. The lifting slide plate is slidably mounted on one side of the frame and is fixedly connected to the clamping cross plate. The lifting cylinder is fixed to the bottom of the frame, and the end of its piston rod is fixedly fitted with connecting sheet metal, which is fixedly connected to the lifting slide plate. The lifting cylinder controls the lifting slide plate to move back and forth in the vertical direction, thereby driving the clamping cross plate to move up and down.

[0009] Furthermore, the working principle of this utility model is as follows: S1, for cylindrical battery testing, the battery is placed in the V-groove of the limiting clamping assembly, and the position of the movable plate is adjusted by adjusting the assembly to make the battery stable; S2, the limiting clamping assembly inputs the clamping data into the battery testing box to complete the testing; S3, for square battery testing, the battery is placed on the clamping horizontal plate, and the clamping plate is controlled by the finger cylinder to clamp the battery; S4, the lifting cylinder drives the lifting sliding plate to move up and down, so that the clamping horizontal plate moves the battery upward until the positive and negative tabs at the top of the battery abut against the connecting electrodes on the electrode positioning plate, realizing electrical connection and completing the testing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the adaptive clamping mechanism, through V-grooves and an adjustable movable plate, solves the problem of existing technologies being unable to adapt to various battery types. Second, the multi-layer detection module setup, with multiple detection modules vertically arranged inside the frame, each module containing a battery detection box, an electrode positioning plate, and a clamping cross plate, significantly improves detection efficiency. Third, the lifting mechanism design, through a combination of a lifting sliding plate and a lifting cylinder, ensures that the clamping cross plate can move precisely up and down, allowing the square battery to accurately contact the electrodes on the electrode positioning plate, thus improving detection accuracy. Fourth, the modular adjustment component design, with a manual operating handle for precise adjustment of the movable plate's position, enhances the equipment's flexibility and applicability.

[0011] In summary, this invention, through innovative structural design and functional integration, achieves efficient and stable testing of cylindrical and prismatic batteries. The adaptive battery clamping and testing cabinet has broad application prospects, especially suitable for scenarios requiring rapid testing of various battery types. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings: An adaptive battery clamping and testing cabinet, combined with an attached Figure 1 To be continued Figure 6 The structural diagram and annotations shown below illustrate the specific implementation method. The testing cabinet includes a frame 15, a limiting clamping assembly 16, testing modules, and a lifting mechanism. The frame 15 serves as the supporting frame for the entire device. The limiting clamping assembly 16 is externally mounted on one side, and multiple testing modules are vertically arranged inside. Data transmission is achieved through an electrical connection between the limiting clamping assembly 16 and the testing modules, thereby enabling efficient testing of various types of batteries.

[0018] The limiting clamping assembly 16 includes a base plate 1, a positioning plate 2, a movable plate 3, a arranging strip 14, an adjustment assembly, and a connector 13. The base plate 1 has a sliding structure to support the horizontal movement of the movable plate 3. Long rectangular adjustment grooves 6 are provided on both sides of the base plate 1 to guide the sliding of the movable plate 3 and allow adjustment of the initial position of the movable plate 3 according to the battery length. The positioning plate 2 is fixed to one side of the base plate 1 and cooperates with the movable plate 3 to form a clamping structure. Both have long elliptical fixing grooves, and the connector 13 is installed in the fixing grooves. The connector 13 is adjustable along the height direction of the fixing groove and locked within the fixing groove. The arranging strip 14 is located between the movable plate 3 and the positioning plate 2, and has downwardly extending V-shaped grooves 4. The width of the V-shaped grooves 4 gradually narrows from top to bottom, forming an adaptive support structure for stably supporting cylindrical batteries of different diameters. The surface of the V-shaped grooves 4 is specially treated to reduce the coefficient of friction, ensuring that the battery is not damaged during clamping.

[0019] The adjustment assembly includes a fixed sheet metal 5, a double-ended positioning block 8, a handle 9, a connecting rod 10, a sleeve 11, and a guide rod 12. The fixed sheet metal 5 is fixedly connected to the base plate 1 by screws and nuts 7. The double-ended positioning block 8 has a sleeve 11 and a handle 9 at each end, with the handle 9 rotatably connected to the double-ended positioning block 8. One end of the connecting rod 10 is hinged to the handle 9, and the other end is rotatably connected to the guide rod 12. The guide rod 12 passes through the sleeve 11 and is slidably connected to it, with its end fixedly connected to the movable plate 3. When the position of the movable plate 3 needs to be adjusted, rotating the handle 9 drives the connecting rod 10 to drive the guide rod 12 to slide horizontally, thereby controlling the horizontal movement of the movable plate 3 and adapting it to batteries of different lengths.

[0020] The testing module includes a battery testing box 17, an electrode positioning plate 21, a clamping horizontal plate 22, and a finger cylinder. The battery testing box 17 is fixedly connected to the frame 15, and the electrode positioning plate 21 is located below it. Multiple horizontally arranged connecting electrodes are fixed on the electrode positioning plate 21 for contacting the positive and negative tabs on the top of the square battery to achieve electrical connection. The clamping horizontal plate 22 is located below the electrode positioning plate 21 and slides along it. The clamping plate is controlled by the finger cylinder to clamp the battery. The clamping horizontal plate 22 is slidably connected to the frame 15 and moves up and down via a lifting mechanism to ensure accurate contact between the square battery and the electrodes on the electrode positioning plate 21.

[0021] The lifting mechanism includes a lifting slide plate 18, a connecting sheet metal 19, and a lifting cylinder 20. The lifting slide plate 18 is slidably disposed on one side of the frame 15 and is fixedly connected to the clamping horizontal plate 22. The lifting cylinder 20 is fixed to the bottom of the frame 15, and the connecting sheet metal 19 is fixedly disposed at the end of its piston rod, which is fixedly connected to the lifting slide plate 18. The lifting cylinder 20 controls the lifting slide plate 18 to move back and forth in the vertical direction, thereby driving the clamping horizontal plate 22 to move up and down.

[0022] Combined with appendix Figure 1 To be continued Figure 6 The working principle and operation process of this utility model are described in detail below. S1, For cylindrical battery testing, the battery is placed in the V-groove 4 of the limiting clamping assembly 16. Rotating the handle 9 drives the connecting rod 10 to drive the guide rod 12 to slide horizontally, thereby controlling the horizontal movement of the movable plate 3 and stabilizing the battery. At this time, the connector 13 is locked in the fixed groove by fasteners to ensure the stability of the clamping structure. The limiting clamping assembly 16 inputs the clamping data into the battery testing box 17 to complete the testing. S2, For square battery testing, the battery is placed on the clamping horizontal plate 22, and the clamping plate is controlled by a finger cylinder to clamp the battery. S3, the lifting cylinder 20 drives the lifting sliding plate 18 to move up and down, causing the clamping horizontal plate 22 to move the battery upwards until the positive and negative tabs at the top of the battery abut against the connecting electrodes on the electrode positioning plate 21, achieving electrical connection and completing the testing.

[0023] In practical applications, the adaptive battery clamping and testing cabinet of this invention is suitable for various scenarios. For example, on a battery production line, cylindrical batteries and prismatic batteries need to be tested simultaneously. Operators only need to place the battery to be tested in the corresponding testing area, and the equipment can automatically complete the clamping and testing tasks. For cylindrical batteries, the limiting clamping assembly 16, through the adaptive support structure of the V-groove 4, can stably support batteries of different diameters, avoiding clamping instability caused by size differences. For prismatic batteries, the clamping plate 22 is controlled by a finger cylinder to clamp the battery, and the lifting cylinder 20 achieves precise up and down movement, ensuring that the positive and negative tabs on the top of the battery accurately contact the electrodes on the electrode positioning plate 21, thereby improving testing accuracy.

[0024] Furthermore, this utility model achieves significant technical effects through the following technical solutions. First, the design of the adaptive clamping mechanism, through the V-groove 4 and the adjustable movable plate 3, solves the problem of the inability to adapt to various types of batteries in the prior art. Second, the setting of multi-layer detection modules, with multiple detection modules vertically arranged inside the frame 15, each module including a battery detection box 17, an electrode positioning plate 21, and a clamping horizontal plate 22, significantly improves detection efficiency. Third, the design of the lifting mechanism, through the combination of the lifting sliding plate 18 and the lifting cylinder 20, ensures that the clamping horizontal plate 22 can move precisely up and down, so that the square battery accurately contacts the electrode on the electrode positioning plate 21, improving detection accuracy. Fourth, the design of the modular adjustment component, through the manual operation handle 9 to precisely adjust the position of the movable plate 3, enhances the flexibility and applicability of the equipment.

[0025] In actual operation, the adaptive battery clamping and testing cabinet of this invention features a high degree of automation and intelligence. For example, when testing cylindrical batteries of various specifications, the operator only needs to adjust the position of the V-groove 4 according to the battery diameter and control the horizontal movement of the movable plate 3 by adjusting the handle 9 in the adjustment assembly to achieve clamping of batteries of different specifications. For prismatic batteries, the equipment drives the clamping horizontal plate 22 to move up and down through the lifting cylinder 20 to ensure that the positive and negative tabs on the top of the battery accurately contact the electrodes on the electrode positioning plate 21. In addition, since multiple horizontally linearly arranged connecting electrodes are fixed on the electrode positioning plate 21, multiple prismatic batteries can be tested simultaneously, further improving the testing efficiency.

[0026] In summary, this utility model, through innovative structural design and functional integration, achieves efficient and stable testing of cylindrical and prismatic batteries. The adaptive battery clamping and testing cabinet has broad application prospects, especially suitable for scenarios requiring rapid testing of various battery types. (See attached...)

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
