Description

Technical Field

[0001] This application relates to the field of testing technology, and in particular to a testing device for welding defects in the chassis of new energy vehicles. Background Technology

[0002] With the increasing number of new energy vehicles, the application of chassis in new energy vehicles is also increasing accordingly. Every user of new energy vehicles is responsible for the defects and safety inspection of the chassis. The chassis is the basic architecture of new energy vehicles and needs to ensure the social traffic safety of new energy vehicles during operation. Therefore, chassis inspection is particularly important.

[0003] Typical chassis welding defect detection uses surveillance cameras for real-time monitoring, and manual inspection of the surveillance footage is used to detect defects in the chassis appearance. However, this method is prone to omissions, as there are always blind spots in the monitoring that cannot fully capture the chassis, or workers may be fatigued and unable to constantly observe the chassis inspection. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a new energy vehicle chassis welding defect detection device.

[0005] The technical solution adopted in this application for a new energy vehicle chassis welding defect detection device is as follows:

[0006] A welding defect detection device for a new energy vehicle chassis includes a detection platform, mounting bases, a rotating component, a receiving component, and a detection component. Two sets of mounting bases are provided, located at opposite ends of the detection platform. The rotating component has a driven end and a driving end, located on the two mounting bases respectively. The receiving component provides support and fixation for the chassis; two sets of receiving components are provided, connected to the driven end and the driving end respectively. The driving end provides the driving force for the receiving component to rotate along the driven end. The detection component is mounted on the detection platform; when the rotating component drives the receiving component and the chassis to rotate, the detection component performs image recognition detection on the chassis.

[0007] By adopting the above technical solution, the receiving component provides the placement and support of the chassis, which is supported by the mounting base and the testing table. After the testing component takes a picture of one side of the chassis, the rotating component can drive the receiving component and the chassis to rotate, so that the other side of the chassis is switched to the opposite side of the testing component. The testing component then performs image recognition testing on the chassis again, thereby achieving all-round identification of chassis defects, improving the efficiency of chassis defect detection, and also improving the pass rate of chassis production or processing.

[0008] Optionally, the testing platform is also provided with a shielding component; the shielding component is a ring-shaped cover that covers the space between the two mounting bases.

[0009] By adopting the above technical solution, the shielding component can effectively block most of the external interfering light, reduce the influence of external light, and ensure the accuracy and clarity of the image during the photographic inspection of the inspection component.

[0010] Optionally, the detection components are provided in two or more sets, evenly distributed on both sides of the detection table.

[0011] By adopting the above technical solution, the visual imaging positions provided by two or more sets of inspection components are different, which can more accurately capture various positions of the chassis and further improve the accuracy of visual inspection.

[0012] Optionally, the inner top surface of the shielding member is further provided with a reflector; the reflector provides an image of the side of the reflector away from the detection member, and the detection member simultaneously identifies and detects the reflected image of the reflector and the image identified on the front of the detection member.

[0013] By adopting the above technical solution, when the inspection component takes a picture of the chassis for identification, it can simultaneously identify the image reflected from the reflector and the image identified from the front of the inspection component, so that both sides of the chassis can be identified at the same time, thereby speeding up the identification efficiency. When combined with multiple sets of inspection components, the accuracy of defect identification can be improved.

[0014] Optionally, the reflector includes a first reflective portion and a second reflective portion; the first reflective portion and the second reflective portion correspond to two sets of the detection elements respectively; there is a preset distance between the first reflective portion and the second reflective portion.

[0015] By adopting the above technical solution, the first reflective part and the second reflective part respectively provide two sets of reflection images of the detection components, so that the reflection images obtained by the two sets of detection components are not shared, and the comparison effect of the obtained reflection image data is more accurate.

[0016] Optionally, the first reflective portion and the second reflective portion have an inclined angle.

[0017] By adopting the above technical solution, the tilt angle can avoid the blind spots of the chassis and completely reflect the side of the chassis away from the testing platform, thereby providing a more complete reflection image.

[0018] Optionally, the reflector further includes a first rotating part, a second rotating part, a bearing part, a rotation drive part, a linkage part, a first gear part, and a second gear part; the first reflector part is connected to the first rotating part, the second reflector part is connected to the second rotating part, and both the first rotating part and the second rotating part are pivotally connected to the bearing part; the first gear part is connected to the first rotating part, and the second gear part is connected to the second gear part; the linkage part is slidably connected to the inner top surface of the shielding member and meshes with the first gear part and the second gear part; the rotation drive part is connected to the linkage part and drives the linkage part to move.

[0019] By adopting the above technical solution, the rotary drive unit drives the linkage unit to move. During the movement, the first and second rotating parts are driven to rotate by the meshing of the first and second gears. When the first and second rotating parts rotate along the bearing part, the first and second reflecting parts tilt. The tilt angle of the first and second reflecting parts can be adjusted according to the pushing distance of the rotary drive unit to adapt to the detection of chassis defects of different sizes.

[0020] Optionally, the testing platform is further provided with a hinge; the testing component is hinged to the hinge.

[0021] By adopting the above technical solution, the inspection piece can be tilted or rotated along the hinge, thereby changing the imaging angle of the inspection piece and obtaining defect identification images from different angles.

[0022] Optionally, the detection component is further provided with a reset part and a push-pull part; one end of the push-pull part is connected to the detection component, and the other end is connected to the linkage part; one end of the reset part is connected to the detection component, and the other end is connected to the detection table.

[0023] By adopting the above technical solution, when both the first and second reflective parts are pushed by the linkage part to rotate and change their angle, the linkage part pulls the push-pull part synchronously, causing the push-pull part to drive the detection component to rotate synchronously, thereby changing the detection angle of the detection component synchronously, adapting to the reflected image of the first or second reflective part, obtaining more complete image information, and achieving higher accuracy in defect identification and detection image comparison results.

[0024] Optionally, both the shielding component and the testing table are equipped with light inspection components, and the two light inspection components illuminate each other in opposite directions.

[0025] By adopting the above technical solution, after blocking the external interference light with the shielding component, the light supply provided by the light inspection component makes the image information captured by the inspection component clearer and more complete.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The receiving component provides placement and support for the chassis, supported by the mounting base and the inspection table. After the inspection component takes a picture of one side of the chassis, the rotating component can drive the receiving component and the chassis to rotate, so that the other side of the chassis is switched to the opposite side of the inspection component. The inspection component performs image recognition inspection on the chassis again, thereby achieving all-round identification of chassis defects, improving the efficiency of chassis defect detection, and also improving the pass rate of chassis production or processing.

[0028] 2. The shielding component can effectively block most of the external interfering light, reduce the influence of external light, and ensure the accuracy and clarity of the image when the test piece is photographed and tested;

[0029] 3. When the inspection component takes pictures of the chassis for identification, it can simultaneously identify the image reflected from the reflective component and the image of the front of the inspection component, so that both sides of the chassis can be identified at the same time, thereby speeding up the identification efficiency. When used with multiple sets of inspection components, it can improve the accuracy of defect identification.

[0030] 4. The first reflective part and the second reflective part provide two sets of reflection images of the detection components, so that the reflection images obtained by the two sets of detection components are not shared, and the comparison effect of the obtained reflection image data is more accurate.

[0042] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0043] This application discloses a welding defect detection device for new energy vehicle chassis.

[0044] A new energy vehicle chassis welding defect detection device is mainly used to separately disassemble the chassis of new energy vehicles and detect visual defects at the welding points.

[0045] refer to Figure 1 As shown, it includes a testing platform 1, a mounting base 2, a rotating component 3, a receiving component 4, and a testing component 5. The testing platform 1 is the main workbench for support and load-bearing. There are two sets of mounting bases 2, located at both ends of the testing platform 1. The mounting bases 2 are installed vertically along the top surface of the testing platform 1, and provide mounting points for components.

[0046] A rotating component 3 is provided on the mounting base 2, and the rotating component 3 is located at the end of the mounting base 2 away from the testing table 1. The rotating component 3 is provided with a driven end and a driving end, which are located on the two mounting bases 2 respectively. The driven end can be a pivot bearing, and the driving end can be a drive motor.

[0047] The receiving component 4 can be a receiving seat, used to provide support and fixation for the chassis. There are two receiving components 4, which are connected to the driven end and the driving end respectively. That is, the receiving seat is connected to a rotating shaft, which is pivotally connected to the pivot bearing of the driven end and the drive motor of the driving end respectively. This allows the driving end to provide driving force for the receiving component 4 to rotate along the driven end. The chassis is placed on the top surface of the two receiving seats and clamped by the receiving seats. When the driving end provides drive, the chassis can synchronously drive the two receiving components 4 to rotate, thereby changing the position of the chassis.

[0048] The receiving component 4 is also equipped with a clamping component, which includes a fixing block, a clamping block, and a screw. The fixing block has a threaded hole. The receiving component 4 is an L-shaped receiving seat. The fixing block is fixedly connected to the receiving component 4, and the clamping block is slidably connected to the receiving component 4. When the chassis is placed on the receiving component 4, the clamping block is located on the top surface of the chassis. Then, the screw is rotated along the threaded hole. The screw continuously descends and abuts against the clamping block, so that the clamping block is pressed against the chassis by the pressure of the screw. Both ends of the chassis are clamped synchronously by the two receiving components 4 and the two clamping blocks, so that the installation is stable and it can avoid falling even under the driving action of the rotating component 3.

[0049] The clamping block and the receiving part 4 are both provided with anti-slip layers. The anti-slip layers can be made of rubber. The anti-slip layers can further increase the friction between the clamping block and the chassis, thereby further ensuring the stability of rotation.

[0050] The testing component 5 is installed on the testing station 1. It can be embedded in the testing station 1 with only the testing end exposed, or it can be directly set on the top surface of the testing station 1. The specific installation position is determined according to the requirements. The figure shows an embedded example.

[0051] Inspection component 5 can be inspected using a visual inspection camera. The visual inspection camera can take pictures of the chassis and compare them with the visual recognition algorithm system in the background to identify defects. That is, the appearance photos of the qualified and complete chassis are compared with the photos taken by the visual inspection camera to detect whether the chassis is damaged or defective.

[0052] The receiving component 4 provides placement and support for the chassis, supported by the mounting base 2 and the inspection table 1. After the inspection component 5 takes a picture of one side of the chassis, the rotating component 3 can drive the receiving component 4 and the chassis to rotate, so that the other side of the chassis is switched to the opposite side of the inspection component 5. The inspection component 5 performs image recognition inspection on the chassis again, thereby achieving all-round identification of chassis defects, improving the efficiency of chassis defect detection, and also improving the pass rate of chassis production or processing.

[0053] In some embodiments, the detection table 1 is also provided with a shielding member 6; the shielding member 6 is a ring-shaped cover, which covers the space between the two mounting bases 2 and can effectively block most of the external light, reduce the influence of external light, and ensure the accuracy and clarity of the image when the detection member 5 is photographed and detected. The detection member 5 is equipped with a flash, which can be used to take and compare images in dark environments to avoid interference from external light.

[0054] Among them, the shielding component 6 can be equipped with an opening and closing door, which allows the chassis to be detached and replaced after the inspection is completed.

[0055] In some embodiments, reference Figure 1 As shown, there are two or more sets of inspection components 5, which are evenly distributed on both sides of the inspection table 1. When there are two or more inspection components 5, the inspection components 5 can be distributed on both sides of the inspection table 1 or the setting angle of the inspection components 5 can be different, so that different images can be captured and identified. This allows the inspection components 5 to simultaneously identify the chassis from multiple angles to obtain multiple sets of comparison images, thereby improving the accuracy of defect identification.

[0056] This embodiment takes two sets as an example. The two sides of the chassis are detected simultaneously by two sets of detection elements 5. The visual shooting positions of the two detection elements 5 are different, which can more accurately shoot various positions of the chassis and further improve the accuracy of visual detection.

[0057] In some embodiments, reference Figure 3 As shown, the inner top surface of the shielding component 6 is also provided with a reflector 7. The reflector 7 can be a plane mirror. The reflector 7 can reflect the image of the side of the chassis away from the detection component 5. When the detection component 5 takes a picture of the bottom surface of the chassis, it can simultaneously identify the image reflected on the reflector 7, that is, the image of the top surface of the chassis, so that both sides of the chassis can be identified simultaneously, thereby speeding up the identification efficiency. With multiple sets of detection components 5, the accuracy of defect identification can be improved.

[0058] Further reference Figure 3 As shown, the reflector 7 includes a first reflector 71 and a second reflector 72, which correspond to two sets of detection elements 5 respectively. There is a preset distance between the first reflector 71 and the second reflector 72. The first reflector 71 can be a first plane mirror, and the second reflector 72 can be a second plane mirror. The two plane mirrors are located on the shielding members 6 on opposite sides of the detection stage 1 and are opposite to the two sets of detection elements 5. This allows the first reflector 71 and the second reflector 72 to provide the reflection images of the two sets of detection elements 5 respectively, so that the reflection images obtained by the two sets of detection elements 5 are not shared, and the comparison effect of the obtained reflection image data is more accurate.

[0059] Furthermore, the first reflective part 71 and the second reflective part 72 have an inclined angle, which can avoid the dead angle of the chassis and completely reflect the side of the chassis away from the detection table 1, thereby providing a more complete reflected image.

[0060] In some embodiments, reference Figure 3 and Figure 4 As shown, the reflector 7 also includes a first rotating part 73, a second rotating part 74, a bearing part 75, a rotation drive part 76, a linkage part 79, a first gear part 77, and a second gear part 78. The first rotating part 73 may be a first rotating shaft, and the second rotating part 74 may be a second rotating shaft. The first reflector 71 is connected to the first rotating part 73, and the second reflector 72 is connected to the second rotating part 74. Both the first rotating part 73 and the second rotating part 74 are pivotally connected to the bearing part 75. The bearing part 75 may be a rotary bearing, so that both the first rotating part 73 and the second rotating part 74 can rotate through the bearing part 75, synchronously driving the first reflector 71 and the second reflector 72 to rotate, thereby changing the tilt angle of the first reflector 71 and the second reflector 72.

[0061] The first gear part 77 is connected to the first rotating part 73, and the second gear part 78 is connected to the second gear part 78. When the first gear part 77 and the second gear part 78 rotate, they can drive the first rotating part 73 and the second rotating part 74 to rotate.

[0062] The linkage 79 is slidably connected to the inner top surface of the shield 6 and meshes with the first gear 77 and the second gear 78. The linkage 79 may include a rack and a slide rail. The slide rail is fixedly installed on the inner top surface of the shield 6 so that the position of the rack is not affected by the annular curved surface of the shield 6. When the rack slides along the slide rail, it can drive the first gear 77 and the second gear 78 to rotate synchronously through meshing.

[0063] The rotary drive unit 76 is connected to the linkage unit 79 and drives the linkage unit 79 to move. The rotary drive unit 76 can be any electrical component such as an electric push rod, a cylinder or a drive motor. Taking an electric push rod as an example, the electric push rod drives the linkage unit 79 to move. During the movement, the first rotating part 73 and the second rotating part 74 are driven to rotate by the first gear and the second gear through meshing. When the first rotating part 73 and the second rotating part 74 rotate along the bearing part 75, the first reflecting part 71 and the second reflecting part 72 are tilted.

[0064] Taking the drive motor as an example, the drive end of the drive motor is connected to any rotating part of the first rotating part 73 or the second rotating part 74, so that when the drive motor drives the first rotating part 73 or the second rotating part 74 to rotate, it drives the first gear or the second gear to rotate. The linkage part 79 meshes with the first gear and the second gear, so it drives the linkage part 79 to move synchronously. During the movement, it drives another gear and another rotating part to rotate, thereby adjusting the tilt angle of the first reflector 71 and the second reflector 72. All of the above drive elements can provide driving action. The illustration uses an electric push rod as an example. The example of the drive motor is not shown in the illustration, but it does not affect the implementation of the embodiment.

[0065] The tilt angle of the first reflector 71 and the second reflector 72 can be adjusted according to the pushing distance of the rotary drive unit 76 to adapt to the detection of chassis defects of different sizes. At the same time, the detection unit 5 can obtain defect recognition images from more angles based on the images reflected by the first reflector 71 and the second reflector 72 at different angles. The comparison of defect recognition images from more angles can obtain more accurate results.

[0066] In some embodiments, reference Figure 5 As shown, the inspection table 1 is also equipped with a hinge 8. The hinge 8 can be a hinge frame. The inspection piece 5 is hinged to the hinge 8, so that the inspection piece 5 can tilt or rotate along the hinge 8, thereby changing the imaging angle of the inspection piece 5 and obtaining defect identification images from different angles.

[0067] This method can be combined with the tilt angle of the first reflector 71 and the second reflector 72 to further reduce the blind spots of the chassis reflection image.

[0068] Furthermore, the hinge 8 is also provided with a reset part 51 and a push-pull part 52; the push-pull part 52 can be a pull rope, one end of the push-pull part 52 is connected to the hinge 8, and the other end is connected to the linkage part 79, so that when the push-pull part 52 is driven by the linkage part 79, it can pull the detection element 5 to rotate along the hinge 8, thereby changing the shooting angle of the detection element 5.

[0069] One end of the reset part 51 is connected to the detection element 5, and the other end is connected to the detection table 1. The reset part 51 can be a reset spring. The reset part 51 provides the function of the detection element 5 to rebound and reset, so that when the detection element 5 loses the pushing and pulling action of the push and pull part 52, it can be reset by the reset part 51.

[0070] Specifically, when the first reflective part 71 and the second reflective part 72 are both pushed by the linkage part 79 and rotate to change their angle, the linkage part 79 simultaneously pulls the push-pull part 52, causing the push-pull part 52 to drive the detection element 5 to rotate synchronously, thereby changing the detection angle of the detection element 5 synchronously, adapting to the reflected image of the first reflective part 71 or the second reflective part 72, obtaining more complete image information, and achieving higher accuracy in defect identification and detection image comparison results.

[0071] Furthermore, the shielding member 6 has a guide channel inside, which is the wiring channel for the push-pull part 52, so that the position of the push-pull part 52 will not shift, and at the same time, it can hide the wiring of the push-pull part 52, so that the inner wall of the shielding member 6 will not be messy due to the wiring of the push-pull part 52.

[0072] In some embodiments, reference Figure 2 As shown, both the shielding component 6 and the inspection table 1 are equipped with light inspection components 9, and the two light inspection components 9 illuminate in opposite directions. The light inspection components 9 can be LED lights, which can provide a stable light source. After the shielding component 6 blocks the light from external interference, the light supply provided by the light inspection components 9 makes the image information captured by the inspection component 5 clearer and more complete.

[0073] The surface of the shielding component 6 can be provided with a reflective coating. The reflective coating can ensure that the light provided by the light inspection component 9 inside the shielding component 6 is fully laid out and spread, so that the chassis can receive sufficient light support during inspection.

[0074] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
