Description

Technical Field

[0001] This utility model relates to the field of automotive cooling plate testing technology, specifically a rapid testing device for the flatness of automotive cooling plates. Background Technology

[0002] In the automotive manufacturing industry, the flatness of the cooling plate, a key component of the vehicle's thermal management system, has a crucial impact on its performance and quality. If the flatness of the cooling plate does not meet requirements, it may lead to assembly difficulties during installation, thereby affecting the normal operation of the entire vehicle's thermal management system, reducing cooling efficiency, and potentially even causing safety hazards.

[0003] Currently, various methods and devices exist for inspecting the flatness of automotive cooling plates, but all have some shortcomings. Traditional flatness inspection methods sometimes rely on manual measurement, such as using feeler gauges for point-by-point measurements. This manual method is not only extremely inefficient, making it difficult to meet the rapid inspection needs of large-scale automotive cooling plate production lines, but the measurement results are also easily affected by the subjective factors of the measuring personnel, leading to unstable measurement accuracy and difficulty in ensuring product quality consistency. Other methods use simple mechanical equipment, which, while improving inspection efficiency to some extent, are limited by their detection principles and structures, allowing only single-point or limited-point measurements. This fails to comprehensively and accurately obtain flatness information of the cooling plate surface. For cooling plates with complex shapes or large dimensions, the measurement error is significant, failing to meet high-precision inspection requirements. Furthermore, some existing inspection devices lack the ability to effectively identify surface defects in cooling plates, only detecting flatness while failing to promptly detect and address potential defects such as scratches and dents. This leads to defective products flowing into the next process, increasing subsequent processing costs and scrap rates. Utility Model Content

[0011] This utility model provides a rapid detection device for the flatness of automotive cooling plates, which has significant advantages over existing technologies, as detailed below: 1. Applications of high-precision laser rangefinder sensor arrays: Precise Measurement: By arranging multiple high-precision laser rangefinders above the detection area of ​​the detection device to form a sensor array, it is possible to simultaneously emit laser beams and receive laser signals reflected back from the surface of the cooling plate. By measuring the time of flight or phase difference of the laser, the distance information of each point on the surface of the cooling plate can be accurately obtained, thereby achieving precise measurement of flatness.

[0012] High-efficiency detection: Multiple sensors work simultaneously, which greatly improves detection efficiency and reduces detection time, making it suitable for the needs of large-scale production lines.

[0013] Data reliability: Multi-sensor data fusion improves the reliability and stability of measurement results and reduces the impact of single-point measurement errors on the overall results.

[0014] 2. Detection assisted by visual sensors: Comprehensive Analysis: A high-resolution industrial camera is used as a vision sensor to acquire surface images of the cooling plate. Image processing algorithms are used to analyze the images, identifying features and defects on the cooling plate surface. Combined with laser ranging data, the accuracy of flatness detection is further improved.

[0015] Rapid marking: Visual sensors can quickly identify and mark non-compliant locations, facilitating subsequent processing and reducing the time and cost of manual intervention.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1-6One embodiment of this utility model is a rapid detection device for the flatness of an automotive cooling plate, which includes a base plate 1, a rotating table 9 and a horizontal support table 7. A fixed table 16 is fixedly supported above the base plate 1 by a support plate 3. A qualified unloading table 17 and an unqualified unloading table 18 are arranged sequentially on the outside of the fixed table 16.

[0027] The base plate 1 serves as the fundamental support component of the entire device, and a fixed platform 16 is fixedly supported on it via a support plate 3. The fixed platform 16 is used to support the servo motor 2 and the rotary table 9 above it. The base plate 1 is preferably made of high-strength steel to ensure the stability and durability of the entire device.

[0028] A qualified unloading platform 17 and an unqualified unloading platform 18 are sequentially arranged on the outer side of the fixed platform 16. The qualified unloading platform 17 and the unqualified unloading platform 18 are used to guide the classification of qualified and unqualified automobile cooling plates after inspection, respectively.

[0029] A servo motor 2 is installed at the center of the bottom of the fixed platform 16. The drive shaft of the servo motor 2 extends to the top of the fixed platform 16 and a rotary table 9 is provided. Rollers 15 are evenly arranged at the bottom of the rotary table 9, and an annular groove 4 is provided on the top of the fixed platform 16 below the rollers 15.

[0030] The top of the rotating platform 9 is uniformly provided with horizontal support platforms 7, and the bottom of the horizontal support platforms 7 is also provided with support columns 10. When one end of the support column 10 contacts the bottom of the settling tank 8, the horizontal support platform 7 is in a horizontal state.

[0031] A servo motor 2 is installed at the center of the bottom of the fixed platform 16. The drive shaft of the servo motor 2 extends above the fixed platform 16 and is connected to the rotary platform 9. The servo motor 2 is a high-precision servo motor to ensure the rotational accuracy and stability of the rotary platform 9.

[0032] Rollers 15 are evenly distributed at the bottom of the rotary table 9. The rollers 15 are preferably made of wear-resistant polymer material to reduce friction and wear. An annular groove 4 is provided on the top of the fixed platform 16 below the rollers 15. The shape of the annular groove 4 matches the rollers 15 to ensure that the rollers 15 roll smoothly in the annular groove 4, thereby realizing the smooth rotation of the rotary table 9.

[0033] The top of the rotating table 9 is uniformly provided with horizontal support platforms 7, which are used to place the car cooling plate to be tested. The bottom of the horizontal support platform 7 is also provided with support columns 10. When one end of the support column 10 contacts the bottom of the sink 8, the horizontal support platform 7 is in a horizontal state.

[0034] The support column 10 is preferably made of high-strength aluminum alloy, which ensures sufficient support strength while reducing the overall weight of the device. The sink trough 8 is located inside the fixed platform 16, and its shape matches the end of the support column 10, ensuring that the support column 10 can accurately fall into the sink trough 8, thereby ensuring the horizontal state of the horizontal support platform 7.

[0035] Bait blocks 5 are set on the rotating platforms 9 on both sides of the horizontal support platform 7, and the horizontal support platform 7 is connected to the bait blocks 5 through the rotating shaft 14. A sinking trough 8 is also set on the top of the rotating platform 9 below the horizontal support platform 7. An electric telescopic rod 6 is installed inside the sinking trough 8 through a movable shaft. The output end of the electric telescopic rod 6 is connected to the bottom of the horizontal support platform 7 away from the bait blocks 5 through the movable shaft.

[0036] The horizontal support platform 7 is connected to the bait block 5 via the rotating shaft 14, ensuring that the bait block 5 can rotate freely on the rotating platform 9.

[0037] The main function of the electric telescopic rod 6 is to adjust the angle of the horizontal support platform 7 through its telescopic movement.

[0038] When the electric telescopic rod 6 extends, the angle of the horizontal support platform 7 increases, allowing the tested product to be automatically unloaded under its own weight.

[0039] An L-shaped upright plate 13 is provided on one side of the fixed platform 16, and a detection top plate 11 is installed at the bottom of the horizontal section of the L-shaped upright plate 13 via a suspension 12. Visual sensors 19 are installed on both sides of the detection top plate 11, and a sensor array 21 is provided at the bottom of the detection top plate 11. The sensor array 21 includes high-precision laser rangefinders 22 that are uniformly fixed at the bottom of the detection top plate 11. Each high-precision laser rangefinder 22 has a movable sleeve 20 on its outer side, and a color marking ring 25 is provided at the bottom of each movable sleeve 20. Miniature telescopic rods 24 are uniformly provided on the top of the detection top plate 11. The output end of the miniature telescopic rod 24 extends to the bottom of the detection top plate 11 and is fixedly connected to the movable sleeve 20.

[0040] Each miniature telescopic rod 24 is connected to each movable sleeve 20 in a one-to-one correspondence, and each miniature telescopic rod 24 is controlled independently.

[0041] The top plate 11 is equipped with holes 23 at the positions corresponding to the miniature telescopic rod 24 for the output end of the miniature telescopic rod 24 to pass through.

[0042] A suspension 12 is installed at the bottom of the horizontal section of the L-shaped vertical plate 13. The structural design of the suspension 12 must ensure that the height and angle of the inspection top plate 11 can be flexibly adjusted to adapt to the inspection requirements of automotive cooling plates of different sizes and shapes. The inspection top plate 11 is installed at the bottom of the horizontal section of the L-shaped vertical plate 13 via the suspension 12, so that the inspection top plate 11 is parallel to the rotary table above the fixed platform 16.

[0043] Vision sensors 19 are installed on both sides of the inspection top plate 11. The vision sensors 19 are high-resolution industrial cameras that can clearly capture surface images of the automotive cooling plate. During installation, ensure that the shooting angle of the vision sensors 19 can cover the entire surface area of ​​the cooling plate in order to comprehensively detect the features and defects on the surface of the cooling plate.

[0044] A sensor array 21 is installed at the bottom of the top plate 11. The sensor array 21 consists of multiple uniformly distributed high-precision laser rangefinders 22. The number and distribution of the high-precision laser rangefinders 22 are determined according to the size of the cooling plate and the detection accuracy requirements to ensure that the surface of the cooling plate is fully covered and to achieve accurate measurement of the flatness of the cooling plate.

[0045] A movable sleeve 20 is installed on the outside of each high-precision laser rangefinder 22. The movable sleeve 20 can move flexibly relative to the high-precision laser rangefinder 22 in the vertical direction. A color marking ring 25 is installed at the bottom of the movable sleeve 20. The color marking ring 25 can be made of different colored materials so that the defect location on the surface of the cooling plate can be clearly marked during the inspection process.

[0046] Miniature telescopic rods 24 are installed on the top of the detection top plate 11. The number of miniature telescopic rods 24 is the same as the number of movable sleeves 20, and they correspond one-to-one. The output end of each miniature telescopic rod 24 passes through the corresponding hole 23 on the detection top plate 11 and is fixedly connected to the movable sleeve 20. This ensures that the installation position of the miniature telescopic rods 24 is accurate, enabling precise control of the movement of the movable sleeve 20.

[0047] When this application embodiment is used, Preparation stage Device startup: Turn on the power to the entire detection device and ensure that the servo motor 2, electric telescopic rod 6, miniature telescopic rod 24, vision sensor 19 and high-precision laser rangefinder 22 are powered on and running normally.

[0048] Position initialization: Servo motor 2 rotates the rotary table 9 to its initial position, placing one of the horizontal support platforms 7 in the loading position. The electric telescopic rod 6 retracts, bringing the horizontal support platform 7 into a horizontal state, with one end of the support column 10 contacting the bottom of the settling tank 8, ensuring the stability of the horizontal support platform 7. The miniature telescopic rod 24 is in its initial retracted state, with the movable sleeve 20 and color marking ring 25 in a high position, not affecting the detection process.

[0049] Material feeding stage The automotive cooling plate to be inspected is placed on the horizontal support platform 7 at the designated loading position, either manually or using automated loading equipment. Ensure the cooling plate is placed stably to prevent shaking or displacement during subsequent inspection.

[0050] Testing phase Rotational positioning: Servo motor 2 starts, driving the rotary table 9 to rotate, and roller 15 rolls smoothly in the annular groove 4, rotating the horizontal support table 7 with the cooling plate to the detection position below the detection top plate 11.

[0051] Flatness measurement: High-precision laser rangefinders 22 simultaneously emit laser beams, which are reflected back after illuminating the surface of the cooling plate. The sensors obtain distance information for various points on the cooling plate surface by measuring the time of flight or phase difference of the laser beams. A sensor array 21 composed of multiple high-precision laser rangefinders 22 fully covers the surface of the cooling plate, enabling accurate measurement of the flatness of the cooling plate. The measurement data is transmitted to the control system in real time for analysis and processing.

[0052] Surface defect detection: Vision sensor 19 (high-resolution industrial camera) acquires surface images of the cooling plate, and the images are analyzed by image processing algorithms to identify features and defects on the surface of the cooling plate, such as scratches and pits.

[0053] Defect Marking: When the vision sensor 19 detects a defect on the surface of the cooling plate, the control system controls the miniature telescopic rod 24 at the corresponding position to extend based on the location information of the defect. The miniature telescopic rod 24 pushes the movable sleeve 20 downward, causing the color marking ring 25 at the bottom of the movable sleeve 20 to contact the surface of the cooling plate, leaving a color mark at the defect location.

[0054] Unloading stage Result judgment: The control system determines whether the cooling plate is qualified based on the flatness data measured by the high-precision laser rangefinder 22 and the surface defect information detected by the vision sensor 19.

[0055] Unloading operation: If the cooling plate is qualified, the servo motor 2 drives the rotary table 9 to rotate the cooling plate to the position corresponding to the qualified unloading table 17. At this time, the electric telescopic rod 6 extends, increasing the angle of the horizontal support platform 7, and the cooling plate automatically slides down onto the qualified unloading table 17 under its own gravity. If the cooling plate is unqualified, the rotary table 9 rotates it to the position corresponding to the unqualified unloading table 18. Similarly, the electric telescopic rod 6 extends, causing the cooling plate to slide down onto the unqualified unloading table 18.

[0056] Reset: After unloading is completed, the electric telescopic rod 6 retracts, restoring the horizontal support platform 7 to a horizontal state, ready for the next loading and inspection.

[0057] Cycle phase By repeating the loading, testing, and unloading process described above, continuous and rapid testing of multiple automotive cooling plates can be achieved. Throughout the operation, the device can be regularly maintained and calibrated to ensure the accuracy of the test results and the stability of the device.

[0058] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
