Description

Technical Field

[0001] The present invention relates to the field of processing of long tubes for cooling new energy batteries, and particularly to a device for detecting the appearance shape of long tubes for cooling new energy batteries. Background Art

[0002] The long tube for battery cooling is a key component of the battery thermal management system, and generally adopts a wavy extension structure design. This special shape significantly improves the heat exchange efficiency by increasing the surface area of the pipeline and optimizing the coolant flow path.

[0003] After the long tube for battery cooling is processed, it is necessary to detect the appearance shape of the long tube for battery cooling to adapt to the installation environment in the middle of the battery. Currently, the technology widely used in the field of high-precision dimensional measurement of industrial products is coordinate measuring machine (CMM). The coordinate measuring machine (CMM) uses a touch probe or a laser probe to measure the surface of the part point by point, and analyzes the CAMBER deviation after generating data. The detector that can move in three directions moves on three mutually perpendicular guide rails. This detector transmits signals in contact or non-contact ways, and the displacement measurement systems of the three axes (such as grating scales) calculate the points (x, y, z) of the workpiece and various function measuring instruments through a data processor or a computer, etc.

[0004] When the coordinate measuring machine (CMM) is used for detecting the long tube for battery cooling, there are certain limitations. Its measurement speed is relatively slow, and the point-by-point measurement takes a long time, which affects the detection efficiency. The operation depends on professional personnel, and has high requirements for the experience and skills of the operator. The measurement error is easily interfered by human factors. Moreover, for workpieces such as large long tubes for battery cooling, the measurement range is limited, and it is necessary to adjust the clamping position or replace the measurement configuration multiple times, and the operation is cumbersome, making it difficult to complete the detection task conveniently.

[0027] The following is a detailed description of the specific embodiments of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0028] As Figures 1 to 6 shown, a detection device for the appearance shape of a long tube for cooling a new energy battery provided by an embodiment of the present invention can realize the detection of two dimensional indexes, namely, bow and camber, as Figure 6As shown, the long battery cooling tube is locally in a regular wavy bending shape along the length direction and is in a state of straight extension along the length direction as a whole. The bow refers to an arc bending degree along the a direction as a whole in the length direction. The camber refers to an arc bending degree along the b direction as a whole in the length direction.

[0029] Specifically, the device includes a support base 1, and a profiling placement table 2 is arranged on the support base 1. The profiling placement table 2 is provided with a wavy upper surface adapted to the shape of the long battery cooling tube. When the long battery cooling tube is placed thereon, the bottom can be closely attached to the wavy upper surface, providing a stable and accurate support basis for subsequent detection.

[0030] The support base 1 is also equipped with a bow detection component 4 for detecting the bow and a camber detection component 6 for detecting the camber. Place the long battery cooling tube on the upper surface of the profiling placement table 2 so that its bottom is adapted to the wavy upper surface, which completes the placement preparation work before detection. Subsequently, the bow detection component 4 and the camber detection component 6 can be used to conduct a comprehensive detection of the long battery cooling tube.

[0031] In a specific embodiment, a plurality of groups of connecting blocks 5 are fixedly arranged on one side of the support base 1. The camber detection component 6 is composed of a plurality of groups of contact displacement sensors 601, and these sensors are respectively fixedly connected to the corresponding connecting blocks 5 for detecting the edge position of the long battery cooling tube. After the detection process is started, the contacts of the plurality of contact displacement sensors 601 will extend synchronously and stop immediately after precisely contacting the side edge of the product. At this time, each sensor will independently record the extended distance, thereby obtaining the values of multiple points. By calculating the difference between the maximum value and the minimum value among these values, the obtained difference is defined as the camber of the product. In an ideal state, the camber of the product should be 0, indicating that the flatness of the product edge position reaches the best state.

[0032] In another specific embodiment, a plurality of groups of through holes 201 are provided in the profiling placement table 2. The bow detection component 4 includes a plurality of groups of second laser displacement sensors 402 arranged at the bottom of the support base 1, and the output end of each group of second laser displacement sensors 402 is precisely located below the corresponding through hole 201. At the same time, a plurality of groups of first laser displacement sensors 401 are also arranged on the upper part of the support base 1. In actual detection, with the collaborative work of the second laser displacement sensors 402 and the first laser displacement sensors 401, the accurate detection of the position of the long battery cooling tube can be realized, and then the bow of the long battery cooling tube can be accurately determined. Its measurement principle is similar to that of camber detection. It also records the position data of multiple points and calculates the difference between the maximum value and the minimum value. This difference is the bow of the product, and the bow of an ideal product should also be 0.

[0033] To ensure the accuracy of the detection results, in a specific embodiment, a calibration block 3 for calibrating the precision of the first laser displacement sensor 401 and the second laser displacement sensor 402 is specifically placed on the profiling placement table 2. Specifically, a placement groove 301 matching the shape of the upper surface of the profiling placement table 2 is formed at the bottom of the calibration block 3, and a calibration groove 302 is formed at the middle position of the top of the calibration block 3. When the calibration block 3 is placed on the profiling placement table 2, the placement groove 301 at the bottom can be adapted to the wavy surface on the profiling placement table 2. In actual calibration operations, the placement groove 301 can be aligned with the output end of the first laser displacement sensor 401. Through this operation, the consistency and accuracy of the first laser displacement sensor 401 can be determined, ensuring the reliability of its measurement data, as Figure 4 shown. Similarly, the placement groove 301 can also be aligned with the through hole 201, and the output end of the second laser displacement sensor 402 can be aligned with the corresponding placement groove 301, thereby determining the consistency and accuracy of the second laser displacement sensor 402 and ensuring the measurement accuracy of the entire detection system.

[0034] During the detection process, to prevent the battery cooling long tube from being misappropriated, in a specific embodiment, a connecting plate 7 is fixedly arranged on one side of the support base 1, a fastening plate 8 is rotatably arranged on the connecting plate 7, and a driving motor for driving one end of the fastening plate 8 to rotate. When the battery cooling long tube is placed on the profiling placement table 2 and the detection starts, the fastening plate 8 rotates so that it lies across the battery cooling long tube, as Figure 1 shown. The L-shaped tail of the fastening plate 8 buckles on the edge of the placement table, and the middle is suspended to cover the pipe fitting. At this time, the fastening plate 8 can visually indicate that the battery cooling long tube is being detected. When the system detects an abnormality in the battery cooling long tube, the fastening plate 8 cannot be automatically lifted, and the operator needs to manually operate the system to turn it on, avoiding the misappropriation of the battery cooling long tube with abnormalities and ensuring the smooth progress of the detection work.

[0035] In modern industrial production, the traceability and management of product information are crucial. In a specific embodiment, a two-dimensional code is attached to one end of the battery cooling long tube, which is used to record the processing steps and production information in detail, providing basic data for the full life cycle management of the product. To facilitate accurately recording the detection information into the production information, a two-dimensional code scanner 9 is arranged at one end of the support base 1. During the detection process, when the battery cooling long tube is placed in place, the two-dimensional code scanner 9 can quickly read the two-dimensional code information, realizing the seamless connection between the detection information and the production information and improving the informatization level of production management. The specific information processing system belongs to the prior art (such as the manufacturing execution system MES), which will not be elaborated here.

[0036] To ensure the normal use of the first laser displacement sensor 401 and the QR code scanner 9, and to prevent the battery cooling long tube from being affected by collisions during placement, in a specific embodiment, a second support column 102 and multiple groups of first support columns 101 are fixedly arranged on the support base 1. Each group of first laser displacement sensors 401 is fixedly mounted on the corresponding first support column 101, and the QR code scanner 9 is fixedly arranged on the second support column 102. Through this design, the first laser displacement sensor 401 and the QR code scanner 9 are far away from the profiling placement table 2 and are in a relatively safe position, ensuring the stability and reliability of the detection device in a complex production environment.

[0037] For the convenience of those skilled in the art to understand, as Figure 1 shown, in a specific embodiment, five groups of first laser displacement sensors 401 are provided and are evenly distributed above the profiling placement table 2. Six groups of second laser displacement sensors 402 are provided and are evenly distributed below the profiling placement table 2 to supplement the detection of the battery cooling long tube from below, forming an up-and-down collaborative detection layout with the first laser displacement sensors 401. Moreover, the first laser displacement sensors 401 and the second laser displacement sensors 402 are arranged in a staggered manner, further improving the detection accuracy. Eleven groups of contact displacement sensors 601 are provided and are evenly distributed on one side of the support base 1, as Figure 1 shown. These contact displacement sensors 601 perform a full-range detection of the battery cooling long tube from the edge position, ensuring the accuracy of the warpage detection. Through the collaborative work of the above-mentioned multiple sensors, this detection device can efficiently and accurately complete the task of detecting the appearance shape of the battery cooling long tube.

[0038] Working principle: The profiling placement table 2 on the support base 1 provides a reference for the detection. The profiling placement table 2 has a wavy upper surface adapted to the battery cooling long tube. When the long tube is placed on it, the bottom of the long tube is in close contact with the wavy surface, completing the positioning placement, providing stable support for subsequent detection of camber, warpage, etc., and reducing the measurement error caused by positioning deviation.

[0039] During the detection, the contacts of the contact displacement sensors 601 extend synchronously and stop after touching the edge of the long tube. Each contact displacement sensor 601 records the distance that the contact extends, that is, the position data of different points on the edge of the long tube. By calculating the difference between the maximum value and the minimum value in these data, the warpage of the long tube is obtained.

[0040] The first laser displacement sensor 401 emits laser from above the long tube to measure the distances from different positions on the upper surface of the long tube to the first laser displacement sensor 401; the second laser displacement sensor 402 emits laser from below through the through hole 201 to measure the distance from the lower surface of the long tube to the first laser displacement sensor 401. By integrating the position data of the upper and lower surfaces, the shape of the long tube in space is determined, and then the arch degree is calculated. Similarly, the difference between the maximum value and the minimum value is used as the arch degree value.

[0041] To ensure the accuracy of the detection results, the device is equipped with a calibration block 3. The placement groove 301 at the bottom of the calibration block 3 is adapted to the wavy surface of the profiling placement table 2, and there is a calibration groove 302 at the top. During calibration, the calibration block 3 is placed on the profiling placement table 2, the placement groove 301 is aligned with the output end of the first laser displacement sensor 401, the sensor emits laser to a specific position in the calibration groove 302, and the consistency and accuracy of the sensor are judged according to the preset standard; then the placement groove 301 is aligned with the through hole 201 to calibrate the second laser displacement sensor 402. In this way, the sensors are calibrated regularly to eliminate measurement errors caused by factors such as sensor aging and environmental changes, and to ensure the measurement accuracy of the detection system.

[0042] When the long tube is placed on the profiling placement table 2 for detection, the clamping plate 8 rotates and lies across the long tube to play a marking role, indicating that the long tube is being detected and ensuring the orderly progress of the detection work. When the system detects an abnormality in the battery cooling long tube, the clamping plate 8 cannot be automatically lifted, and the staff needs to manually operate the system to turn it on to prevent the abnormally cooled battery long tube from being misappropriated, ensuring the smooth progress of the detection work. At the same time, a two-dimensional code recording the processing steps and production information is pasted on one end of the long tube, and a two-dimensional code scanner 9 is arranged at one end of the support seat. During the detection process, the two-dimensional code scanner 9 reads the two-dimensional code information, associates the detection data with the production information, realizes the traceability and management of product information, and facilitates subsequent quality tracking and production process optimization.

[0043] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
