[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] Reference Figure 1-6The electrode burr detection device provided in this embodiment of the utility model includes a base (composed of a base, cabinet, etc.), a touch panel for operation on the base, and built-in corresponding image processing software. A support unit is connected to the base via a loading / unloading motion module 8 (which can be an electric slide rail mechanism), allowing the support unit to move in the X-axis direction on the base. The support unit can be a platform 1. The device also includes a scanning motion module and an imaging module 3. Specifically, the scanning motion module includes a vertical motion module 9 connected to the bottom of the imaging module 3, and a horizontal motion module 10. The bottom of the vertical motion module 9 is connected to the base via the horizontal motion module 10. The horizontal motion module 10 and the vertical motion module 9 are respectively responsible for the imaging module 3 in the Y-axis and X-axis directions. The vertical motion module 9, which moves along the Z-axis, is an electric scissor lifting platform driven by a stepper motor. This allows the imaging module 3 to move. The cooperation between the slide rail mechanism, the horizontal motion module 10, and the vertical motion module 9 creates a three-axis motion relationship between the platform 1 and the imaging module 3, namely, an XYZ three-axis motion relationship. The wiring between the imaging module 3 and the base is handled by a tank chain 2 to prevent the wiring from becoming messy and to protect the wires. Through the linear movement of the imaging module 3, a scanning area, or measurement area, is formed on the base for imaging scanning. The base is also equipped with positioning components, specifically a first support point 4 and a second support point 5, which are fixed at fixed positions on the base. The support points can adopt a block-like shape structure.

[0030] The working process of this equipment is as follows:

[0031] First, the manual debugging part, namely:

[0032] Input and output settings and display;

[0033] The lifting and lowering adjustment of the platform 1's vertical motion module;

[0034] The loading and unloading motion module 8 is pushed in, withdrawn, and returned to its original position; the working distance of the lens in the horizontal direction.

[0035] Settings for scanning, retrace, and return to origin of the scanning motion module;

[0036] Vertical motion module 9 adjusts the vertical working distance of the lens;

[0037] Automatic detection process section:

[0038] 1. Manually pick up the material and place it on the carrier 1, aligning the edges of the electrode sheet using positioning components;

[0039] 2. Manually smooth the electrode sheet. A covering part can also be set here. The covering part can adopt the structure of the pressure plate 6. One end of the pressure plate 6 is movably connected to the platform 1. The platform 1 is also provided with a pressing element 7 that acts on the other end of the pressure plate 6. After the electrode sheet is placed on the platform 1 and smoothed, the electrode sheet can be flattened by lowering the pressure plate 6.

[0040] 3. Press the start button to begin the automatic operation. For detailed steps, please refer to:

[0041] The loading and unloading motion module 8 pushes the stage 1 and the electrode into the measurement area;

[0042] The scanning motion module 2, carrying the CCD imaging module 3, moves linearly while simultaneously scanning and imaging, moving from the set starting point to the ending point.

[0043] While scanning and imaging, the loading / unloading motion module 8 and the vertical motion module 9 automatically focus the two lenses in the horizontal and vertical directions based on the offset information fed back from the image.

[0044] The detection software analyzes the photographed images and outputs the dimensions of each burr.

[0045] The scanning motion module returns to the starting point;

[0046] The loading and unloading motion module 8 retracts the carrier 1 and the electrode sheet back to the loading position;

[0047] The results are manually confirmed, and a retest can be selected.

[0048] After confirming the results, the material is manually removed, and the process continues until the next feeding.

[0049] Compared with the current technology, this utility model can achieve at least the following technical effects:

[0050] For electrode burrs, one-click automatic high-precision burr detection is achieved with a detection accuracy of 1µm and a time of less than 30 seconds. This not only reflects the high precision of the measurement, but also ensures the measurement efficiency.

[0051] By designing the platform 1 and positioning components, the position can be automatically aligned after manual loading, and the alignment degree is <1mm;

[0052] The design includes a stage 1 and a pressure plate 6, which press down after the material is loaded to solve the problem of overall product warping, thereby avoiding product damage and improving scanning accuracy.

[0053] The design incorporates two sets of cameras / lenses / light sources / prisms, which simultaneously capture images of the electrode end face and the plane in two mutually perpendicular directions, thus accommodating measurement needs in more locations.

[0054] Inspection software & algorithm: For each product, the system takes images while scanning, and based on image processing algorithms, it automatically finds the edges and burrs in the image, detects burrs that exceed the specified dimensions, outputs report data and uploads it to the MES system, thus facilitating the acquisition of measurement results.

[0055] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
