Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of electroplated parts appearance detection, and in particular relates to electroplated parts appearance detection equipment and a detection system thereof. Background Art
[0002] Electroplating is a process of covering the surface of a substrate with a layer of metal or alloy, which aims to improve the appearance, corrosion resistance and mechanical properties of the material. Electroplated parts are widely used in industries such as automobiles, aviation, electronics, construction and decoration. Their appearance quality is directly related to the overall quality and market competitiveness of the product. In order to ensure that the surface of the electroplated parts is free of defects, scratches, cracks, etc., the use of appearance inspection equipment for appearance inspection is an important part of the electroplating production process.
[0003] In the Chinese patent with publication number CN113834815A, a device for real-time detection of appearance defects of electroplated decorative parts is mentioned. Through the installation box and industrial camera set on the plate body, when the high-brightness LED lamp is powered on and emits light, the light will be irradiated on the light-distributing plate, so that the light will be evenly irradiated from the opening of the installation box along the axial direction of the installation box, and will be irradiated on the detection surface of the electroplated part. Multiple groups of high-brightness LED lamps can emit light counterclockwise in 1 second, and each group of high-brightness LED lamps will quickly go out after emitting light. Each light-emitting cycle is completed within 0.08s, and the light is reflected by the detection surface of the electroplated part, so that the industrial camera can receive the parallel light reflected from the electroplated part. Because the surface plane of the electroplated part is smooth and flat, and the defects are not on the same plane, the image collected by the camera only has the defects, so as to avoid the problem of too strong reflection in the formed image and resulting in a reduced detection rate; However, when the detection equipment is in use, it can only detect one side. Since the electroplated parts may have complex shapes and structures, this detection method is difficult to fully cover the entire surface of the electroplated parts. Therefore, it is impossible to accurately and comprehensively detect all possible surface defects. This not only affects the accuracy of the test results, but also reduces the versatility of the detection equipment, making it difficult for the equipment to adapt to the detection needs of electroplated parts of different types and shapes.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] See also Figures 1 to 7 As shown, the electroplating parts appearance inspection equipment includes: Detecting the chassis 1 and the turning mechanism 3; Detection mechanisms 4 are installed on both sides of the top of the detection chassis 1. Three coaxial lighting mechanisms 5 are installed inside the detection mechanism 4 on one side, and a shadowless lighting mechanism 6 is installed inside the detection mechanism 4 on the other side. The flip mechanism 3 includes a fixed frame 31, an adjustment frame 32, a driver 33, a forward and reverse screw 34, a flip frame 35, a proximity sensor 36 and a rotating motor 37. The adjustment frame 32 is installed on the top of the fixed frame 31 through a bearing, and the adjustment frame 32 is installed on the bottom end of the electric telescopic rod 7. The driver 33 is installed on the outer wall of the fixed frame 31, and the forward and reverse screws 34 are installed between the inner walls on both sides of the fixed frame 31 through bearings. Two flip frames 35 are provided, and the two flip frames 35 are respectively installed on both sides of the outer surface of the forward and reverse screws 34. The proximity sensor 36 is installed at one end of the fixed frame 31, and the rotating motor 37 is installed on the bottom inner wall of the adjustment frame 32.
[0021] Depend on Figures 1 to 3 It can be seen that a support frame 2 is installed at the middle of the top of the detection chassis 1, an electric telescopic rod 7 is installed at the top of the support frame 2, and the bottom end of the electric telescopic rod 7 is installed at the top of the flip mechanism 3, a control panel 8 is installed at the lower part of the outer wall of the support frame 2, and a conveyor belt 9 is installed between the inner walls of both sides of the detection chassis 1; The flip frame 35 includes a flip plate 351, a guide groove 352, a drive motor 353, a flip block 354, a storage chamber 355, a clamping rod 356 and a spring 357. The flip plate 351 is installed on the outer surface of the forward and reverse screws 34, the guide groove 352 is opened at the top of the flip plate 351, the drive motor 353 is installed on the lower side of one end of the flip plate 351, and the flip block 354 is installed on the lower side of the other end of the flip plate 351 through a bearing. There are multiple storage chambers 355, clamping rods 356 and springs 357. Multiple storage chambers 355 are opened inside the flip block 354, and multiple clamping rods 356 are respectively inserted and installed on the inner walls of the multiple storage chambers 355. Multiple springs 357 are respectively installed on the inner walls of the other side of the multiple storage chambers 355, and the other ends of the multiple springs 357 are respectively installed on the other ends of the multiple clamping rods 356.
[0022] As can be seen from the above, when the proximity sensor 36 detects that the electroplated part is approaching, the detection data is transmitted to the control panel 8, so that the control panel 8 controls the electric telescopic rod 7, the driver 33, the drive motor 353 and the rotating motor 37 to start. First, the electric telescopic rod 7 extends to push the adjustment frame 32 to move downward, and the two flip frames 35 are moved to the side of the electroplated part. Then the driver 33 drives the forward and reverse screws 34 to rotate, and drives the two flip plates 351 to drive the two flip blocks 354 to move toward the middle respectively, so that the multiple clamping rods 356 clamp the electroplated part together. At this time, through the elasticity of the plurality of springs 357, the clamping rod 356 can be retracted into the storage cavity 355, and then it can It clamps electroplated parts of different materials and shapes, which is suitable for electroplated parts with complex shapes and structures. Then, the driving motor 353 drives the flip block 354 to rotate, so that the two flip blocks 354 flip the electroplated parts together. Subsequently, the rotating motor 37 drives the fixed frame 31 to rotate, and then the two flip frames 35 also drive the electroplated parts to rotate. This mechanism ensures that all surfaces of the electroplated parts are detected, so that all possible surface defects can be accurately and comprehensively detected. This not only improves the comprehensiveness of the detection and ensures the accuracy of the detection results, but also improves the versatility of the detection equipment, so that the equipment can adapt to the detection needs of electroplated parts of different types and shapes.
[0023] Specifically, refer to Figures 1 to 3 As shown, the clamping rod 356 is set as a T-shaped structure, the guide groove 352 is slidably connected to the fixed frame 31, and the drive motor 353, the driver 33, the proximity sensor 36, the rotating motor 37, the electric telescopic rod 7 and the conveyor belt 9 are all electrically connected to the control panel 8.
[0024] As can be seen from the above, the clamping rod 356 will not be separated from the storage cavity 355, and the fixed frame 31 will limit the flip plate 351, thereby improving the stability of the flip plate 351 during the adjustment process. These devices can be controlled and coordinated through the control panel 8 to achieve automation or remote operation.
[0025] refer to Figure 4 and Figure 5 As shown, the detection mechanism 4 includes a fixing frame 41, a supporting frame 42, a reinforcement block 43 and a detection assembly 44. Two supporting frames 42 are provided, and the two supporting frames 42 are installed at the bottom end of the fixing frame 41. Four reinforcement blocks 43 are provided, and the four reinforcement blocks 43 are respectively installed at the top and bottom ends of the two supporting frames 42. Three detection assemblies 44 are provided, and the three detection assemblies 44 are respectively installed on the inner walls of the fixing frame 41 and the two supporting frames 42. The detection component 44 includes a mounting bracket 441, an infrared sensor 442, an industrial camera 443, and a laser sensor 444. The mounting bracket 441 is installed on the inner wall of the fixing bracket 41, and the infrared sensor 442, the industrial camera 443, and the laser sensor 444 are arranged and installed at the bottom end of the mounting bracket 441 from left to right.
[0026] As can be seen from the above, during the process of detecting the appearance of the electroplated part, the electroplated part is placed on the conveyor belt 9, which can drive the electroplated part to pass through the two detection mechanisms 4 in sequence. The left detection mechanism 4 performs appearance detection on three sides of the electroplated part, and the right detection mechanism 4 performs appearance detection on the other three sides of the electroplated part. During the detection process, the three-dimensional information of the surface of the electroplated part is obtained through the laser sensor 444 to improve the accuracy and comprehensiveness of the detection; the detailed information on the surface of the electroplated part is captured through the industrial camera 443 with high resolution and high frame rate; finally, the temperature change on the surface of the electroplated part is detected through the infrared sensor 442 to assist in identifying defective or abnormal areas. This detection device can more accurately identify defects on the surface of the electroplated part, such as scratches, unevenness, color differences, etc., by integrating data from multiple sensors, thereby improving the accuracy of the detection, reducing the misjudgment rate, and enhancing the reliability of the detection.
[0027] Preferably, as shown in Figure 4 and Figure 5 , the mounting bracket 441, the fixing bracket 41, and the support bracket 42 are all set as U-shaped structures, and the infrared sensor 442, the industrial camera 443, and the laser sensor 444 are all electrically connected to the control panel 8.
[0028] As can be seen from the above, the U-shaped structure may help to provide a stable support or mounting platform, which is suitable for mounting or fixing other devices or components. These sensors can collect, monitor, or control data through the control panel 8 to achieve intelligent or automated detection.
[0029] As shown in Figure 6 and Figure 7 , the coaxial illumination mechanism 5 includes a mounting plate 51, mounting rods 52, through holes 53, mounting bolts 54, and a coaxial light source 55. There are four mounting rods 52 and four mounting bolts 54. The four mounting rods 52 are respectively installed at the four corners of the top end of the mounting plate 51, and the top ends of the four mounting rods 52 are all installed on the outer wall of the corresponding industrial camera 443. The through hole 53 is opened in the middle of the top end of the mounting plate 51. The four mounting bolts 54 are respectively installed on the four sides of the top end of the mounting plate 51. The coaxial light source 55 is installed at the bottom end of the mounting plate 51 through the mounting bolts 54; The shadowless lighting mechanism 6 includes a fixing plate 61, a fixing rod 62, a through opening 63, a fixing bolt 64 and a diffuse reflection shadowless light source 65. There are four fixing rods 62 and four fixing bolts 64. The four fixing rods 62 are respectively installed at the four corners of the top of the fixing plate 61, and the tops of the four fixing rods 62 are all installed on the outer wall of the corresponding industrial camera 443. The through opening 63 is opened in the middle of the top of the fixing plate 61, and the four fixing bolts 64 are respectively installed on the four sides of the top of the fixing plate 61. The diffuse reflection shadowless light source 65 is installed at the bottom end of the fixing plate 61 through the fixing bolts 64.
[0030] As can be seen from the above, when it is necessary to inspect electroplated parts with mirror-smooth surfaces, the fixing is canceled by rotating the fixing bolt 64, the diffuse reflection shadowless light source 65 is removed from the fixing plate 61, and the coaxial light source 55 is installed, so that multiple industrial cameras 443 correspond to multiple coaxial light sources 55. When it is necessary to inspect electroplated parts with complex shapes or requiring uniform lighting, the fixing is canceled by rotating the mounting bolt 54, the coaxial light source 55 is removed from the mounting plate 51, and the diffuse reflection shadowless light source 65 is installed, so that multiple industrial cameras 443 correspond to multiple diffuse reflection shadowless light sources 65. In this way, a suitable lighting source can be selected according to the type of electroplated parts to enhance the detection effect, make defects more obvious in the image, and facilitate identification by operators or algorithms.
[0031] Preferably, reference Figure 6 and Figure 7 As shown, the diameters of the through hole 53 and the through opening 63 are both larger than the diameter of the lens on the industrial camera 443 , and the coaxial light source 55 and the diffuse reflection shadowless light source 65 are respectively located directly below the corresponding industrial camera 443 .
[0032] As can be seen from the above, ensuring that the lens of the industrial camera 443 can smoothly pass through the through hole 53 and the through port 63 for shooting or detection can provide suitable lighting conditions for the industrial camera 443 to ensure the accuracy and reliability of shooting or detection.

The lighting unit is used to provide suitable lighting conditions for image acquisition, enhance image contrast, and make defects easier to identify. The image acquisition card unit is used to convert the analog signal output by the camera unit into a digital signal for computer processing. The image processing unit is used to preprocess the collected image to improve the image quality and facilitate the subsequent feature extraction and defect identification. The feature extraction unit is used to extract the feature information of the surface of the electroplated part from the preprocessed image. The defect identification unit is used to identify the defects on the surface of the electroplated part according to the preset standards and algorithms. The data storage unit is responsible for storing the collected image data, the processed image data and the detected defect information. The defect classification unit is used to classify the identified defects to facilitate subsequent processing and analysis. The defect marking unit is used to mark the detected defect locations to facilitate production personnel to quickly locate the problems. The report generation unit is used to generate a detailed test report based on the test results to provide a basis for quality control and improvement.

The human-computer interaction unit is used to provide a friendly user interface to facilitate production personnel to operate the detection equipment and view the detection results. The alarm unit is used to trigger the alarm device to remind production personnel to deal with it in time when serious defects or equipment failures are detected.
[0034] As can be seen from the above, when the entire inspection system is in use, the camera unit captures the surface image of the electroplated part according to the set parameters (such as resolution, frame rate, exposure time, etc.) to ensure that the image is clear and accurate. The lighting unit selects the appropriate light source type and lighting method according to the material and surface characteristics of the electroplated part to make the defect features in the image obvious. The image acquisition card unit receives the image signal output by the camera, performs analog-to-digital conversion, and transmits the digital image data to the image processing end. The image processing unit performs denoising, enhancement, segmentation and other processing on the collected image to eliminate interference factors and highlight defect features. The feature extraction unit uses algorithms to extract edge, texture, color and other features in the image to provide basic data for defect identification. The defect identification unit compares the extracted features with the preset defect template to determine whether the defect exists and determine the defect type and location. The data storage unit provides large capacity and high The high-speed storage medium ensures the integrity and security of data, which is convenient for subsequent analysis and quality traceability. The defect classification unit divides defects into different categories such as scratches, cracks, pits, etc. according to the defect characteristics and types.

The human-computer interaction unit displays the system operation status, test results and other information, and supports production personnel to operate equipment through keyboard, mouse, etc. The alarm unit sends out alarm signals through sound, light and other means according to the preset alarm conditions to prompt production personnel to pay attention to the problem. Through the joint cooperation of these units, a comprehensive inspection of the appearance of electroplated parts can be completed.
[0035] Application examples: This design is used in the quality inspection of electroplated parts in industrial production. On the electroplating production line, after the electroplating treatment, the electroplated parts need to be inspected for appearance quality to ensure that they meet the quality standards. This equipment can be integrated into the production line to achieve automated and efficient inspection. In the quality inspection department of the enterprise, the equipment is used to sample or fully inspect the electroplated parts to ensure stable product quality.

This design greatly improves the detection efficiency, avoids missed detection, and can adapt to the detection of electroplated parts of different materials and shapes without a large number of adjustments or replacements of parts. The detection mechanism 4 is composed of an infrared sensor 442, an industrial camera 443 and a laser sensor 444, which can capture the image, contour and defect information of the surface of the electroplated parts. By fusing these data, the equipment can more accurately identify defects such as scratches, bumps, and color differences, thereby improving the accuracy of detection and reducing the misjudgment rate.
