Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and in particular relates to a circular battery shaping and testing device. Background Technology

[0002] In the current battery production field, there are many shortcomings in battery shaping and testing technologies. Traditional battery shaping equipment is mostly designed for square or regular-shaped batteries, lacking effective means to shape round batteries. It is difficult to accurately mold batteries into the required circular structure, requiring manual, step-by-step shaping using molds and experience—first shaping the sides, then the ends—resulting in low production efficiency and poor shaping results. Furthermore, in the testing stage, existing testing equipment cannot conveniently and accurately inspect the shaping effect of round batteries; relying solely on visual judgment makes it impossible to accurately determine whether the round battery formation meets requirements. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] To overcome the above shortcomings, the purpose of this utility model is to provide a circular battery shaping and testing device to solve the technical problems of low battery production efficiency, poor shaping effect, and inability to accurately detect the shaping effect of circular batteries after shaping.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] A circular battery shaping and testing device includes: a mounting base; a first driving device mounted on the mounting base and capable of moving up and down; a shaping base located below the mounting base and corresponding to the first driving device, the shaping base forming a first semi-circular shaping groove for placing the battery; a first shaping head located at the end of the driving end of the first driving device and having a second semi-circular shaping groove, which moves downward under the drive of the first driving device and cooperates with the shaping base to shape the side of the battery into a cylindrical shape; second shaping heads symmetrically arranged at both ends of the shaping base and having a circular structure; and a second driving device connected to at least one second shaping head, capable of driving the corresponding second shaping head to move towards the end of the battery, so that the two second shaping heads respectively squeeze the end of the battery to form a circle.

[0008] The first driving device drives the first shaping head downwards to cooperate with the shaping seat, realizing automated shaping of the battery side. Compared with the traditional manual mold shaping method, this embodiment can significantly improve shaping efficiency and accuracy, reduce manual intervention, and ensure the consistency of the battery side shape. The second driving device drives the second shaping head to squeeze the battery end face, realizing precise shaping of the battery end face. In addition, the use of double-sided synchronous squeezing can effectively avoid the battery deformation problem caused by single-sided shaping, ensure the symmetry and roundness of the battery end shape, and further improve the overall shaping effect of the battery. The battery shaping and testing device of this application can improve production efficiency and product quality.

[0009] In some embodiments, one of the second shaping heads is fixedly disposed;

[0010] By fixing one shaping head and controlling the movement of the other shaping head by a second drive device, the equipment structure is simplified, and manufacturing costs and maintenance difficulties are reduced.

[0011] In some embodiments, it further includes: pressure sensors respectively disposed on the second shaping head for detecting the pressure of the compression when the second shaping head compresses the two end faces of the battery;

[0012] The introduction of pressure sensors makes the shaping process more controllable. By monitoring the extrusion pressure in real time, battery damage or poor shaping caused by excessive or insufficient pressure can be avoided, ensuring the safety and consistency of the shaping process and further improving the product qualification rate.

[0013] In some embodiments, it further includes: a battery detection holder, comprising two identical opening and closing members that are hinged to each other, each of the opening and closing members having a semi-circular detection groove;

[0014] The semi-circular detection groove on the opening and closing parts allows for convenient and accurate evaluation of the battery's shaping effect, avoiding subjective errors caused by human eye judgment and improving the reliability and efficiency of the test. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] This utility model provides a circular battery shaping and testing device, which achieves its function through two-stage collaborative operation. First, the side shaping unit consists of a mounting base 1, a first driving device 5, a shaping seat 3, and a first shaping head 2. The mounting base 1 serves as an integral support structure, with the first driving device 5 (e.g., a hydraulic cylinder or electric push rod) fixed to its top, and the shaping seat 3 with a first semi-circular shaping groove 301 at its bottom. When the battery is horizontally placed within the first semi-circular shaping groove 301 of the shaping seat 3, the first driving device 5 drives the first shaping head 2 to press vertically downwards. A second semi-circular shaping groove 201 is formed on the first shaping head 2, corresponding to the first semi-circular shaping groove 301 of the shaping seat 3, closing to form a complete circular cavity. Through mechanical extrusion, the side of the battery is shaped into a regular cylindrical shape. The key to this stage lies in the stroke control accuracy of the driving device, ensuring complete alignment of the upper and lower cavities and uniform pressure distribution. After completing the side shaping, the device transitions to the end-face shaping stage. A pair of circular second shaping heads 4 are symmetrically arranged on both sides of the shaping base 3. At least one second shaping head 4 is connected to a second driving device (such as a pneumatic push rod or servo motor). The second driving device pushes the second shaping head 4 to move horizontally, forming a bidirectional synchronous extrusion on the battery end. By adjusting the advance speed and pressure parameters of the second driving device, the forming size and surface finish of the end face can be precisely controlled. The two-stage operation is linked by a timing controller to achieve fully automatic continuous shaping from the side to the end face.

[0022] To further simplify the equipment structure, this design optimizes the movement of the second shaping head 4. Specifically, the second shaping head 4, located on one side of the shaping base 3, is rigidly fixed and directly connected to the mounting base 1 via a bracket, eliminating the need for an additional drive mechanism. The corresponding second shaping head 4 on the other side retains its drive mechanism, creating a working mode of single-sided active propulsion and dual-sided coordinated pressure application. This design significantly reduces equipment complexity while ensuring the axial positioning accuracy of the battery during the extrusion process through the reaction force of the fixed-side second shaping head 4. In practical applications, a fine-tuning mechanism (such as a threaded adjustment rod) can be installed at the mounting position of the fixed-side second shaping head 4 to facilitate rapid calibration of the initial spacing according to different battery lengths.

[0023] In the end-face shaping unit, high-precision pressure sensors are embedded in the working faces of both second shaping heads 4. When the second drive device pushes the movable shaping head to squeeze the battery end, the pressure sensors on the fixed and movable sides synchronously collect real-time pressure data and transmit it to the control system through the data acquisition module. The system presets a pressure threshold range (e.g., 50-200N, the specific value is set according to the battery material characteristics). If the measured pressure exceeds the threshold, an alarm is immediately triggered and the drive device is paused to avoid battery casing rupture or internal structural damage due to overpressure. In addition, the pressure data can be stored in a local database for subsequent quality traceability and process parameter optimization, such as statistical analysis of the correlation between specific pressure ranges and end-face roundness.

[0024] The battery testing unit 6 is located downstream of the shaping station as an independent module, consisting of two hinged opening and closing parts 601. The inner side of each opening and closing part 601 has a semi-circular testing groove 6011 that matches the diameter of the target battery. The groove surface is polished and marked with graduations. During operation, the shaped battery is horizontally placed into the testing groove 6011 of the lower opening and closing part 601. After closing the upper opening and closing part 601, it is observed whether the two opening and closing parts 601 can be completely closed and the fit between the outer contour of the battery and the testing groove 6011 is observed. If the two opening and closing parts 601 fail to close completely, it indicates that the side diameter of the battery is too large and has not been shaped to the appropriate size. If there is a visible gap between the circumferential surface of the battery and the testing groove 6011, it indicates that the side shaping is too small and does not meet the standard. If the end extends beyond the edge of the testing groove 6011, it reflects insufficient end-face shaping accuracy. To improve detection efficiency, a developing coating can be applied to the inner wall of the detection tank 6011. After the battery comes into contact with the tank, an indentation is formed. The image recognition system automatically determines whether the continuity of the indentation meets the preset standard.

[0025] The above-mentioned plastic surgery process will be described in detail:

[0026] Material loading and positioning stage: The operator places the battery to be shaped horizontally in the first semi-circular shaping groove 301 of the shaping seat 3, with the battery axis aligned with the moving direction of the second shaping head 4.

[0027] Side shaping stage: The first drive device 5 is activated, which drives the first shaping head 2 to press down until it closes with the shaping seat 3. The pressure is maintained for 3-5 seconds and then reset.

[0028] End face shaping stage: The second drive device pushes the second shaping head 4 on the movable side to move horizontally, and the pressure sensors on both sides monitor the pressure changes in real time. After reaching the set value, the pressure is maintained for 2-3 seconds.

[0029] Inspection and judgment stage: Remove the battery and place it into the inspection seat 6. Close the opening and closing part 601 to check the shape matching. Qualified products are transferred to the next process, and unqualified products are returned to the shaping station.

[0030] The entire process is automated through a PLC control system. The interval time and pressure parameters of each stage can be flexibly adjusted through the human-machine interface to adapt to the production needs of batteries of different specifications.

[0031] Summary of the technical advantages of this application:

[0032] This solution integrates side shaping, end-face shaping, and inspection functions into a single device through modular design, increasing production efficiency by approximately 60% compared to traditional step-by-step operations. The application of dual-sided pressure sensing and closed-loop control technology reduces the product defect rate from over 15% with manual operation to below 3%. The quantitative evaluation function of the inspection module effectively eliminates subjective judgment errors, providing data support for process improvement. Furthermore, the combination of a fixed-side shaping head design and a single-side drive reduces equipment manufacturing costs while ensuring accuracy.
