[0033] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0036] This invention provides a testing mechanism that can be used to perform appearance inspection on batteries during the battery production process.

[0037] like Figure 1 As shown, the testing organization provided by this utility model includes:

[0038] The first carrier 1 and the first detection group 2, the first detection group 2 including three first detection cameras, the first carrier 1 is used to carry the battery 001 to be tested, the first carrier 1 can drive the battery 001 to be tested to the first detection group 2, so that the three first detection cameras of the first detection group 2 can simultaneously detect the three sides of the battery 001 to be tested.

[0039] The second carrier 3 and the second detection group 4, the second detection group 4 including three second detection cameras, the second carrier 3 is used to transfer the battery to be tested 001 from the first carrier 1, the second carrier 3 can drive the battery to be tested 001 to the second detection group 4, so that the three second detection cameras of the second detection group 4 can simultaneously detect the other three sides of the battery to be tested 001.

[0040] Specifically, the first carrier 1 can be equipped with a clamp or suction cup for fixing the battery 001 to be tested. The design of the clamp can be customized according to the shape and size of the battery 001 to be tested, ensuring that the battery can be stably fixed on the first carrier 1 during the testing process. The first carrier 1 can move under the drive of a motor, cylinder or other driving component, and move the battery 001 to be tested on it between the loading station, the first testing station and the transfer station, so as to realize the testing of multiple batteries 001 to be tested.

[0041] like Figure 2 As shown, the first detection group 2 includes three first detection cameras, which can be positioned above, in front of, and behind the movement trajectory of the first carrier 1, respectively, forming a three-sided detection area. Each first detection camera is a high-resolution industrial camera to clearly capture image information of the battery surface. Simultaneously, each first detection camera is also equipped with a high-precision lens and light source to ensure high-quality detection images are obtained under various lighting conditions.

[0042] When the first carrier 1 moves the battery 001 to be tested to the first testing group 2, i.e., the first testing station, the three first testing cameras are positioned opposite the three sides of the battery 001. At this time, the three first testing cameras start simultaneously and perform synchronous testing on the top, front, and rear sides of the battery 001. During the testing process, the image data captured by the three first testing cameras can be transmitted to a computer for image processing and analysis.

[0043] Similarly, the second carrier 3 can also be equipped with clamps or suction cups for fixing the battery 001 to be tested. The design of the clamps can be customized according to the shape and size of the battery 001 to be tested, ensuring that the battery can be stably fixed on the second carrier 3 during the testing process. The second carrier 3 can move under the drive of a motor, cylinder, or other driving component, and move the battery 001 to be tested on it between the transfer station, the second testing station, and the unloading station, so as to facilitate the testing of multiple batteries 001 to be tested.

[0044] like Figure 3As shown, the second detection group 4 includes three second detection cameras. These three cameras can be positioned below, to the left, and to the right of the movement trajectory of the second carrier 3, or below, in front of, and behind the movement trajectory of the second carrier 3, respectively, thus forming a three-sided detection area. Each second detection camera uses a high-resolution industrial camera to clearly capture image information of the battery surface. Simultaneously, each second detection camera is equipped with a high-precision lens and light source to ensure high-quality detection images are obtained under various lighting conditions.

[0045] After the first carrier 1 completes the inspection of the three sides of the battery 001 to be inspected, the second carrier 3 moves to the transfer station and transfers the battery 001 to be inspected from the first carrier 1 to the second carrier 3 by a robotic arm or other gripping device.

[0046] When the second carrier 3 moves the battery 001 to be tested to the second detection group 4, i.e., the second detection station, the three second detection cameras are aligned with the other three sides of the battery 001. At this time, the three second detection cameras start simultaneously and perform synchronous detection on the other three sides of the battery 001. During the detection process, the image data captured by the three second detection cameras can be transmitted to a computer for image processing and analysis.

[0047] In one embodiment, when the three second detection cameras are respectively placed on the lower, front, and rear sides of the movement trajectory of the second carrier 3, the battery 001 to be tested on it can be rotated 90 degrees by the second carrier 3 so that the other three sides of the battery 001 to be tested can be opposite to the three second detection cameras one by one.

[0048] This testing facility utilizes a collaborative approach between the first testing group 2 and the second testing group 4. The battery 001 to be tested is precisely positioned onto the first testing group 2 via the first carrier 1, where three first testing cameras simultaneously inspect three sides of the battery. Subsequently, the second carrier 3 transfers the battery from the first carrier 1 and precisely moves it to the second testing group 4, where three second testing cameras simultaneously inspect the remaining three sides of the battery. This design achieves comprehensive and efficient testing of all six sides of the battery, avoiding the low efficiency issues caused by multiple battery position adjustments or the use of multiple devices in traditional testing methods. It significantly shortens the testing cycle and substantially improves the overall efficiency of battery production. Furthermore, the precise positioning of the first carrier 1 and the second carrier 3 avoids the risk of low reliability of test results due to multiple battery repositioning, and the testing facility has a simple structure and high reliability.

[0049] During the inspection process, cameras in the first inspection group 2 and the second inspection group 4 can acquire image data of the battery surface in real time and quickly transmit the data to a computer for processing and analysis. Once a defect is detected on the battery surface, the system can immediately record detailed information such as the location, size, and type of the defect and provide real-time feedback to the operators or production management system. This real-time detection and rapid feedback mechanism enables production personnel to promptly identify and handle defective batteries, effectively preventing defective products from flowing into the next process and improving product quality and production efficiency.

[0050] Furthermore, the clamp design of the first and second carrier components 1 and 3 of this testing mechanism is highly flexible, allowing for quick replacement and adjustment according to different specifications and models of the batteries to be tested (001). Whether it is a small button battery or a large power battery, this testing mechanism can perform appearance inspections on different batteries simply by changing the corresponding clamps. This flexible design enables the testing mechanism to be widely used in various battery production scenarios, and also improves the versatility and utilization rate of the testing mechanism.

[0051] Compared to traditional multi-unit testing equipment, this testing organization integrates multiple testing functions into one unit, reducing the floor space and number of testing units, lowering procurement costs, and facilitating transportation.

[0052] Optionally, the testing mechanism may also include two, three or more first carriers 1 and two, three or more second carriers 3. Each first carrier 1 is used to carry one battery 001 to be tested. After the previous battery 001 to be tested is tested, it is transferred to the second carrier 3 at the transfer station, and the next battery 001 to be tested can be tested at the first testing station. This enables continuous testing of multiple batteries 001 to be tested, thereby improving the testing efficiency of the testing mechanism.

[0053] Optionally, at least one of the first detection camera and the second detection camera is a CIS camera.

[0054] Specifically, the first and / or second detection cameras can be configured as CIS (Contact Image Sensor) cameras. CIS cameras can integrate more photosensitive units per unit area, enabling the capture of finer features and defects on the battery surface during image acquisition of the battery 001 under inspection. For example, CIS cameras can clearly image minute scratches, cracks, or surface protrusions that may exist on the battery surface, with a significantly improved resolution compared to traditional cameras. This provides a high-quality image data foundation for subsequent image analysis and defect detection, greatly improving the accuracy and reliability of defect detection.

[0055] Furthermore, since the CIS camera integrates a light source, it allows for rapid model changeovers by adding servo drives or quick-connect structures, eliminating the need for separate adjustments to the light source and camera. This facilitates quick model changes and adaptability to batteries of different sizes under test. Moreover, the CIS camera uses diffuse illumination, achieving uniform lighting and thus highly reproducing the surface details of the battery under test, contributing to high-precision inspection.

[0056] Furthermore, CIS cameras are characterized by their compact structure, being smaller and lighter. Using CIS cameras in the inspection mechanism reduces the overall volume of the first inspection group 2 and the second inspection group 4, resulting in a more compact structure. This not only facilitates layout and installation within limited space but also reduces manufacturing costs. Simultaneously, the compact design improves the movement flexibility and stability of the inspection mechanism, reducing vibration and interference caused by excessive equipment size, thereby enhancing inspection accuracy and reliability.

[0057] Optionally, the first detection group 2 further includes a first bracket 22, which is used to set three first detection cameras so that the three first detection cameras can face the three sides of the battery 001 to be tested one by one.

[0058] And / or, the second detection group 4 further includes a second bracket 42 for setting three second detection cameras, such that the three second detection cameras can be aligned with the other three surfaces of the battery 001 to be tested.

[0059] Specifically, the first bracket 22 is used to support and mount three first detection cameras, so that the three first detection cameras can be aligned one-to-one with the three sides of the battery 001 under test, so that the three first detection cameras can perform synchronous detection on the three sides of the battery 001 under test. The second bracket 42 is used to support and mount three second detection cameras, so that the three second detection cameras can be aligned one-to-one with the other three sides of the battery 001 under test, so that the three second detection cameras can perform synchronous detection on the other three sides of the battery 001 under test.

[0060] Optionally, the first bracket 22 includes a first support rod 221, a second support rod 222 and a third support rod 223, wherein the third support rod 223 is vertically connected between the first support rod 221 and the second support rod 222, and the first support rod 221 and the second support rod 222 are parallel and opposite to each other.

[0061] And / or, the second bracket 42 includes a fourth support rod 421, a fifth support rod 422 and a sixth support rod 423, wherein the sixth support rod 423 is vertically connected between the fourth support rod 421 and the fifth support rod 422, and the fourth support rod 421 and the fifth support rod 422 are parallel and opposite to each other.

[0062] like Figure 2 As shown, each support rod is equipped with a first detection camera. The first support rod 221 and the second support rod 222 can be set to extend vertically, and the third support rod 223 can extend horizontally, so that the three first detection cameras respectively set on them can face the three sides of the battery 001 to be tested one by one, so that the three first detection cameras can perform synchronous detection on the three sides of the battery 001 to be tested.

[0063] like Figure 3 As shown, each support rod is equipped with a second detection camera. The fourth support rod 421 and the fifth support rod 422 can be set to extend vertically, and the sixth support rod 423 can extend horizontally, so that the three second detection cameras respectively set on them can be aligned with the other three surfaces of the battery 001 to be tested, so that the three second detection cameras can perform synchronous detection on the other three surfaces of the battery 001 to be tested.

[0064] Specifically, one of the third support rod 223 and the sixth support rod 423 is positioned so that the top surface of the battery 001 to be tested is faced to detect the top surface of the battery 001 to be tested, and the other of the third support rod 223 and the sixth support rod 423 is positioned so that the bottom surface of the battery 001 to be tested is faced to detect the bottom surface of the battery 001 to be tested.

[0065] Optionally, the first bracket 22 and the second bracket 42 are arranged in parallel, with part of the first bracket 22 facing the top surface of the battery 001 to be tested and part of the second bracket 42 facing the bottom surface of the battery 001 to be tested.

[0066] like Figure 1 As shown, the two supports can be arranged along a direction perpendicular to the movement trajectory of the battery 001 to be tested, that is, along... Figure 1 The arrangement of the battery 001 perpendicular to the paper in the front-back direction enables visual inspection during its movement, which helps to make the testing agency more compact and reduces the production and installation costs of the testing agency.

[0067] The first bracket 22 is positioned so that the top surface of the battery 001 under test can be inspected, enabling the inspection of three surfaces of the battery 001, including the top surface. The second bracket 42 is positioned so that the bottom surface of the battery 001 under test can be inspected, enabling the inspection of the remaining three surfaces of the battery 001, including the bottom surface.

[0068] Optionally, it also includes a rotation drive, the output end of which is connected to the second carrier 3. Under the drive of the rotation drive, the second carrier 3 can rotate the battery 001 to be tested on it, so that the other three sides of the battery 001 to be tested can be aligned with the three second detection cameras of the second detection group 4.

[0069] like Figure 1 As shown, when the three second detection cameras are respectively placed on the lower, front and rear sides of the movement trajectory of the second carrier 3, the second carrier 3 and the battery 001 to be tested on it can be rotated 90 degrees by the rotation drive first, so that the bottom, left and right sides of the battery 001 to be tested can be aligned with the three second detection cameras one by one, thereby facilitating the appearance inspection of the other three sides of the battery 001 to be tested by the three second detection cameras.

[0070] Optionally, it also includes a first linear drive and a second linear drive. The output end of the first linear drive is connected to the first carrier 1, and the first linear drive can drive the first carrier 1 to move and approach the first detection group 2. The output end of the second linear drive is connected to the second carrier 3, and the second linear drive can drive the second carrier 3 to move and approach the second detection group 4.

[0071] Specifically, the first linear drive unit includes, but is not limited to, a linear motor and a linear cylinder, which drives the first carrier 1 to move in a horizontal linear direction and moves the battery 001 to be tested on it to the testing station of the first testing group 2 for appearance inspection. The second linear drive unit includes, but is not limited to, a linear motor and a linear cylinder, which drives the second carrier 3 to move in a horizontal linear direction and moves the battery 001 to be tested on it to the testing station of the second testing group 4 for appearance inspection.

[0072] Optionally, it also includes a base, on which a first guide rail and a second guide rail are provided. The first support member 1 is slidably disposed on the first guide rail, and the second support member 3 is slidably disposed on the second guide rail. One of the first guide rail and the second guide rail is opposite to the top surface of the battery 001 to be tested, and the other of the first guide rail and the second guide rail is opposite to the bottom surface of the battery 001 to be tested.

[0073] Specifically, the base is used to set up and support the first support member 1, the second support member 3, the first linear drive member, the second linear drive member, and other structures. A first guide rail is provided on the base, and the extension direction of the first guide rail is a horizontal straight line. The first support member 1 is slidably placed on the first guide rail, so that the first support member 1 can move along the first guide rail to the detection station of the first detection group 2, and the movement process is reliable and stable.

[0074] Similarly, a second guide rail is also provided on the base. The second guide rail extends in a horizontal straight line. The second support member 3 is slidably mounted on the second guide rail, allowing it to move along the second guide rail to the detection station of the second detection group 4, and the movement process is reliable and stable. The first guide rail and the second guide rail are respectively aligned with the top and bottom surfaces of the battery 001 to be tested, so that the three different surfaces of the battery 001 to be tested can be exposed, thereby facilitating the detection function.

[0075] Optionally, it also includes a first movable seat 5 and a second movable seat 6, wherein the first movable seat 5 is used to carry the first carrier 1 and move the first carrier 1 closer to the first detection group 2, and the second movable seat 6 is used to carry the second carrier 3 and move the second carrier 3 closer to the second detection group 4.

[0076] like Figure 1 As shown, the first carrier 1 can also be mounted on the frame of the detection structure via the first movable seat 5, so that the first movable seat 5 can drive the first carrier 1 and the battery 001 to be tested on it to move together to the detection station of the first detection group 2 for appearance inspection. The second carrier 3 can be mounted on the frame of the detection structure via the second movable seat 6, so that the second movable seat 6 can drive the second carrier 3 and the battery 001 to be tested on it to move together to the detection station of the second detection group 4 for appearance inspection.

[0077] Optionally, the first carrier 1 has a first suction cup 11, which is used to adsorb the bottom surface of the battery 001 to be tested;

[0078] And / or, the second carrier 3 has a second suction cup 31, which is used to adsorb the top surface of the battery 001 to be tested.

[0079] like Figure 1 As shown, the first suction cup 11 can adsorb the bottom surface of the battery 001 to be tested and reliably fix the battery 001 to be tested on the first carrier 1, thereby ensuring reliable appearance inspection at the first detection group 2.

[0080] When the first carrier 1 moves the battery 001 to the transfer station, the first suction cup 11 closes to remove the suction force on the battery 001. At this time, the second suction cup 31 of the second carrier 3 located at the transfer station opens, allowing the second suction cup 31 to adsorb the top surface of the battery 001, so as to reliably fix the battery 001 to the second carrier 3 and realize the transfer of the battery 001, thereby ensuring reliable appearance inspection at the second inspection group 4.
