Description

Technical Field

[0001] The utility model relates to the technical field of intelligent detection of vehicle specifications, and in particular to a dynamic inspection device for vehicle specifications. Background Art

[0002] Specification inspection refers to the inspection and confirmation of incorrect and missing parts of vehicle assembly. That is, it is to confirm whether the vehicle is equipped with corresponding parts, and whether the types and specifications of the assembled parts are accurate.

[0003] At present, most domestic manufacturers use manual visual inspection to confirm whether the parts of the vehicle body are missing or mis-installed by comparing with the configuration table. This method relies on manual sensory judgment and is affected by the state of the inspectors (fatigue, mood), so the quality assurance is not high and there is a risk of defective outflow; and because there are many sample inspection items (no less than 130 items / model), the number of personnel implementing sample inspection exceeds 4 people / shift. The operator's man-hours are too large, and there are many accompanying movements such as bending and squatting, which poses a risk of occupational diseases.

[0004] There are also a small number of manufacturers that have tried to introduce equipment inspection solutions, using cameras to collect pictures of the assembly status of parts, comparing them with standard assembly part templates, and judging the identification and detection results. The relevant equipment setting solutions mainly include the following two:

[0005] The first solution is to fix the camera on a fixed beam and use a fixed camera combined with a fixed light source to collect data. However, this collection method is single and inflexible, and cannot achieve more accurate position collection. When the shooting position and angle do not match well, it is difficult to inspect parts at specific angles, such as the internal parts of the engine compartment. In addition, the compatibility is low, and it is difficult to correspond to new models, requiring new hardware to correspond. The large number of cameras used results in a large cost waste.

[0006] The second solution is to fix the acquisition camera on the robot arm and use the robot's joints to move to achieve flexible posture and angle acquisition. However, this solution also has the problem of insufficient installation space and high maintenance and introduction costs. Utility Model Content

[0034] The main purpose of the utility model is to provide a vehicle specification dynamic inspection device, which aims to solve the problems of deviation in the shooting and collection effect of the imported equipment, inability to achieve more accurate position collection and inspection, and poor compatibility.

[0035] like Figure 1 As shown, the first direction is from front to back; the second direction is from top to bottom; and the third direction is from left to right.

[0036] The utility model provides a vehicle specification dynamic inspection device.

[0037] like Figures 1 to 4As shown, in one embodiment of the utility model, a vehicle specification dynamic inspection device 100 includes a bracket 2 and a plurality of image acquisition mechanisms 3; the driving mechanism 1 includes a plate chain 11 that can move along a first direction, and the plate chain 11 is used to carry and transport the vehicle; the driving mechanism 1 also includes a detection unit, and the detection unit is used to obtain the position information of the vehicle; the bracket 2 includes a crossbeam 21 and vertical beams 22 respectively connected to the two ends of the crossbeam 21, and the ends of the two vertical beams 22 away from the crossbeam 21 are connected to the ground; the two vertical beams 22 are respectively located on both sides of the plate chain 11, and the crossbeam 21 is located on the top of the plate chain 11; the plurality of image acquisition mechanisms 3 include a first image acquisition mechanism 3a and a second image acquisition mechanism 3b, the number of the first image acquisition mechanisms 3a is two, and each first image acquisition mechanism 3a is respectively connected to each vertical beam 22 in a one-to-one correspondence, and the first image acquisition mechanism 3a is connected to the crossbeam 21, and the image acquisition mechanism 3 is used to move and shoot the vehicle specification image according to the vehicle position information.

[0038] In one embodiment, after the vehicle moves onto the plate chain 11, a dynamic inspection of the vehicle's specifications begins. First, the plate chain 11 carries and carries the vehicle from front to back, and then the specific moving position of the vehicle is obtained through the detection unit, and the real-time position of the vehicle is fed back to the processor, the image acquisition mechanism 3; then the image acquisition mechanism 3 moves to the detection position for shooting according to the vehicle position information fed back by the processor. The first image acquisition mechanism 3a is located on both sides of the plate chain 11, and is used to shoot the specifications images of the left and right sides of the vehicle when it moves. The second image acquisition mechanism 3b is located at the top of the plate chain 11, and is used to shoot the specifications images of the front and back and the left and right sides of the vehicle.

[0039] The technical solution of the utility model adopts a vehicle specification dynamic inspection device 100, which realizes all-round shooting through the image acquisition mechanism 3 set on the crossbeam 21 and the vertical beam 22, and detects and feeds back the specific moving position of the vehicle through the set detection unit, so as to control the image acquisition mechanism 3 to move and shoot, which can not only realize image collection and inspection at a more precise position, make the shooting effect better, and avoid shooting deviation, but also when adding a new model or adding new hardware, the image acquisition mechanism 3 can be controlled to move and shoot by changing or adding the detection position, thereby improving the compatibility of the imported equipment.

[0040] Specifically, the detection unit may be an encoder or a sensor, and the detection unit may be disposed inside the plate chain 11 or on both sides of the plate chain 11 to detect the specific moving position of the vehicle. The embodiment of the utility model does not limit the type and installation position of the detection unit.

[0041] like Figure 3As shown, in the first embodiment, in order to be able to flexibly capture images, more accurately position when shooting, and avoid deviations, the image acquisition mechanism 3 includes an image acquisition component 31 and a drive component 32, the drive component 32 is connected to the vertical beam 22 or the horizontal beam 21, and the output end of the drive component 32 is connected to the image acquisition component 31. The drive component 32 is used to drive the image acquisition component 31 to slide along the second direction, or the drive component 32 is used to drive the image acquisition component 31 to reciprocate linearly along the second direction and the third direction.

[0042] The image acquisition component 31 of the first image acquisition mechanism 3a can slide up and down along the vertical beam 22. Therefore, the height of the image acquisition component 31 can be adjusted according to the needs of vehicle specification inspection to achieve more accurate positioning, so as to capture the specification images of the left and right sides of the vehicle when it moves, avoiding shooting deviation; the two second image acquisition mechanisms 3b are arranged at intervals along the cross beam 21, and can respectively capture the specification images of the left and right sides of the vehicle. The image acquisition component 31 of the second image acquisition mechanism 3b can be driven by the driving component 32 to reciprocate linearly left and right and reciprocate linearly up and down along the cross beam 21. According to the needs of vehicle specification inspection, the position of the image acquisition component 31 in the vehicle width direction (i.e., the left and right direction) can be adjusted first, and then the image acquisition component 31 can be adjusted to move up and down to reach a more accurate shooting position, so that images can be flexibly captured to avoid shooting deviation.

[0043] Specifically, the driving component 32 of the second image acquisition mechanism 3b can adopt two linear guide modules, the base of the first linear guide module is connected to the crossbeam 21, the slider of the first linear guide module is vertically connected to the base of the second linear guide module, and the slider of the second linear guide module is connected to the image acquisition component 31. The first linear guide module is used to realize left and right reciprocating linear motion, and the second linear guide module is used to realize up and down reciprocating linear motion, so that the image acquisition component 31 can reach a more precise shooting position to avoid shooting deviation.

[0044] In other embodiments, the drive assembly 32 may also use a motor or a cylinder to drive a gear and a rack to achieve reciprocating linear motion. This embodiment does not limit the type of the drive assembly 32.

[0045] Based on the above embodiment, in order to adjust the shooting posture and angle of the image acquisition component 31, the image acquisition component 31 includes a pan-tilt 311 and a detection head 312, the pan-tilt 311 is connected to the output end of the corresponding driving component; the pan-tilt 311 is connected to the detection head 312, and the pan-tilt 311 is used to control the rotation of the detection head 312; in the first image acquisition mechanism 3a, the pan-tilt 311 is slidably connected to the vertical beam 22, the detection head 312 is connected to the pan-tilt 311, and the detection head 312 can realize up and down reciprocating linear motion and rotation through the pan-tilt 311; in the second image acquisition mechanism 3b, the pan-tilt 311 is connected to the driving component 32 The detection head 312 is connected to the pan-tilt head 311 by a sliding connection. The detection head 312 realizes up and down reciprocating linear motion, left and right reciprocating linear motion and rotation through the driving component 32 and the pan-tilt head 311. Compared with only using a fixed camera, the present embodiment uses the pan-tilt head 311 and the detection head 312, and can adjust the shooting posture and angle according to the moving position of the vehicle, so as to realize the acquisition and shooting at different spatial positions corresponding to different vehicle positions, thereby approaching the ideal position and ideal angle to shoot the sample image facing the assembly part, thereby improving the flexibility of image acquisition and realizing clear acquisition of each assembly part to be inspected.

[0046] Specifically, the pan / tilt head in the above embodiment is an existing structure, and the pan / tilt head 311 includes a horizontal motor and a vertical motor. The horizontal motor is used to drive the detection head 312 to rotate horizontally, and the vertical motor is used to drive the detection head 312 to rotate up and down; when the detection head 312 needs to rotate horizontally to adjust the shooting angle, the horizontal motor can be started; when the detection head 312 needs to rotate up and down to adjust the shooting angle, the vertical motor can be started; when the detection head 312 needs to be moved again to adjust the shooting angle, the horizontal motor and the vertical motor can also be started at the same time, so that the detection head 312 can be adjusted to the ideal position and ideal angle through horizontal rotation and up and down rotation.

[0047] Furthermore, in order to improve the shooting effect and realize clear and shadowless acquisition, the detection head 312 is a camera, and the image acquisition component 31 also includes a light source 313 arranged on both sides of the camera; specifically, the camera can adopt a zoom camera. Compared with a fixed camera, the zoom camera can solve the problem of shooting distance differences caused by different sizes of assembly parts in various places, and realize clear acquisition of each assembly part to be inspected; in the traditional solution, the general light source 313 is evenly arranged on the outside of the equipment. Although it can achieve indiscriminate lighting coverage of the vehicle, the shooting and acquisition effect is not good for shadow areas such as the engine compartment. The design of this solution bundles the camera and the light source 313 into a whole. When the camera moves and rotates to the specified position, the integrated light source 313 will illuminate the collected area vertically and directly, realizing clear and shadowless acquisition, while also reducing the number of lighting and saving energy.

[0048] The detection head 312 may specifically use an electronic zoom lens to achieve automatic focusing of target positions at different intervals and realize clear acquisition.

[0049] In the second embodiment, in order to improve the shooting and collecting effect, the vehicle specification dynamic inspection device 100 also includes a darkroom 4, the driving mechanism 1, the bracket 2 and the image acquisition mechanism 3 are all arranged in the darkroom 4, the darkroom 4 forms an entrance and an exit at both ends along the first direction, and the plate chain 11 drives the vehicle to move from the entrance to the exit; in the traditional scheme, the vehicle specification dynamic inspection device 100 is directly exposed to the factory building. Due to the high sensitivity of machine vision inspection, the change of the external light source 313 will affect the illumination of the picture collection, thereby affecting the accuracy of the detection result. The present scheme designs a darkroom 4, encloses the driving mechanism 1, the bracket 2 and the image acquisition mechanism 3 in the darkroom 4 as a whole, and arranges opaque materials. When the plate chain 11 drives the vehicle to move from the entrance to the exit, the image acquisition mechanism 3 shoots the vehicle specification image to prevent the external light source 313 from shining in and affecting the inspection.

[0050] In this embodiment, the interior of the darkroom 4 is made of opaque material, which may be an opaque film, a light-shielding cloth or a black felt. This embodiment does not limit the opaque material.

[0051] Furthermore, in order to determine whether there is a vehicle that needs to be inspected, a beam switch 5 is provided on both sides of the entrance of the darkroom 4, and the beam switch 5 is used to detect the position information of the vehicle; specifically, the beam switch 5 is used to detect whether the vehicle is located at the entrance of the darkroom 4, and the beam switch 5 can be used in conjunction with the detection unit, and the beam switch 5 is used to control the reset of the detection unit. If the beam switch 5 detects that the vehicle is located at the entrance of the darkroom 4, it means that the vehicle needs to be inspected, and the vehicle inspection dynamic inspection device 100 can be started to work, and then the position information of the vehicle is detected by the detection unit.

[0052] Based on the above embodiment, in order to realize an all-round inspection of the vehicle, the vehicle specification dynamic inspection device 100 also includes a tire detection mechanism 6. The number of the tire detection mechanisms 6 is two. The two tire detection mechanisms 6 are arranged in the darkroom 4 and are respectively arranged on both sides 11 of the plate chain; specifically, the tire detection mechanism 6 may include a dome-type light source and a fixed-focus color camera. In the process of the plate chain 11 carrying and transporting the vehicle from front to back, when the tires of the vehicle move to the position of the tire detection mechanism 6, the tires of the vehicle can be inspected to determine whether the tires of the vehicle meet the inspection requirements, thereby realizing a more comprehensive dynamic inspection of the vehicle specifications.

[0053] The utility model also proposes a dynamic inspection method, which is used for a vehicle type dynamic inspection device. The specific structure of the vehicle type dynamic inspection device refers to the above embodiment. Since the dynamic inspection method adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, after the vehicle to be inspected moves to the plate chain, the dynamic inspection method includes:

[0054] S10, controlling the plate chain to move along a first direction;

[0055] S20, obtaining the position of the vehicle to be inspected on the plate chain in real time;

[0056] S30, moving the image acquisition mechanism to the next preset detection position, and adjusting the parameters of the image acquisition mechanism to match the preset detection position;

[0057] The preset detection points are obtained according to the vehicle information, and each preset detection point of the vehicle has a corresponding detection position and camera parameter information of the mobile image acquisition mechanism. Specifically, the camera parameter information may include the camera shooting angle (pan-tilt rotation angle), camera focal length, exposure, and aperture settings. That is, different shooting parameters are set for different detection points to improve the clarity of the acquired sample images. That is, the driving component drives the image acquisition component to reach the preset shooting position in advance, and the driving component realizes the movement control of the second and third directions; at the same time, the pan-tilt adjusts the camera shooting angle and adjusts the parameters of the camera lens (zoom). The above operations are implemented simultaneously, which can reduce the preparation time for shooting.

[0058] S40, when the vehicle to be inspected moves to the preset inspection point, the image acquisition mechanism takes a sample image of the vehicle;

[0059] S50, repeatedly executing the step of moving the image acquisition mechanism to the next preset detection position until the vehicle to be inspected moves to a preset end point.

[0060] Specifically, after the vehicle to be inspected is moved onto the plate chain 11, the plate chain 11 is controlled to move from front to back, and at the same time, the plate chain 11 carries and transports the vehicle to be inspected from front to back; at this time, the detection unit on the plate chain 11 can detect the real-time position information of the vehicle to be inspected, and transmit the real-time position information of the vehicle to be inspected to the image acquisition mechanism 3; the image acquisition mechanism 3 moves to the next detection position in advance according to the real-time position information of the vehicle to be inspected fed back by the detection unit, and adjusts the shooting angle; when the vehicle to be inspected moves to the preset detection point, the image acquisition mechanism 3 takes the vehicle sample image of the preset detection point; then repeat the step of moving the image acquisition mechanism 3 to the next detection position in advance until the vehicle to be inspected moves to the preset end point, and all sample images are taken. Using the collected vehicle assembly parts pictures (sample images), AI technology is used to determine whether there are mis-installed or missing parts.

[0061] The technical solution of the utility model adopts a dynamic inspection method, which is used for a vehicle specification dynamic inspection device 100. By acquiring the position information of the vehicle on the plate chain 11 in real time, the image acquisition mechanism 3 is controlled to move to the detection position in advance, and the vehicle specification image is photographed. The dynamic inspection method has a high degree of automation and can realize the specification inspection of the entire vehicle without human participation, and can realize more accurate position collection and inspection, and the shooting effect is better.

[0062] In the first embodiment, for the vehicle to be inspected, it is necessary to obtain vehicle information in advance, obtain preset inspection points based on the vehicle information, and generate a motion trajectory of the image acquisition mechanism 3 based on the moving distance between each preset inspection point and the length direction of the vehicle; specifically, before performing a dynamic inspection on a certain vehicle to be inspected, it is necessary to first obtain the specific position information of the vehicle that needs to be inspected for specifications, preset inspection points for the vehicle based on the specific position information of the specifications inspection, and then plan the moving trajectory of the image acquisition mechanism 3 to each inspection position based on the preset inspection points of the vehicle and the moving distance between the length direction of the vehicle; when performing dynamic inspection on the vehicle, the moving trajectory of the image acquisition mechanism 3 is preset in advance, and the image acquisition mechanism 3 only needs to move to the corresponding inspection position according to the information fed back by the inspection unit; and when a new vehicle model or new hardware is added, the image acquisition mechanism 3 can be controlled to reach the changed or newly added inspection position by changing or adding the moving trajectory of the image acquisition mechanism 3 in advance, thereby improving the compatibility of the dynamic inspection method.

[0063] Based on the above embodiment, the step of moving the vehicle to be inspected to the plate chain includes: before the step of obtaining the position of the vehicle to be inspected on the plate chain in real time, it also includes:

[0064] Step S11, determining whether the vehicle has reached a preset starting point;

[0065] If yes, the position of the vehicle to be inspected on the plate chain is obtained in real time.

[0066] Specifically, the beam switch 5 is used to detect whether the vehicle has reached a preset starting point. The beam switch 5 can be used in conjunction with the detection unit. The beam switch 5 is used to control the reset of the detection unit. If the beam switch 5 detects that the vehicle has reached the preset starting point, the detection unit is reset and the real-time position of the vehicle to be inspected on the plate chain 11 is re-acquired.

[0067] In another embodiment, in order to perform a more comprehensive inspection on the vehicle, the dynamic inspection method further includes inspecting the tires, by setting a tire inspection mechanism 6 to inspect the tires of the moving vehicle.

[0068] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
