Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of an offline inspection system provided in the present invention.
As shown in fig. 1, the present invention provides an offline inspection system, comprising: the device comprises a vision darkroom 1, wherein a shooting part and a light source are arranged in the vision darkroom 1, and the shooting part is usually a camera and is used for shooting an actual measurement image of a part to be measured; the movable frame 2 is connected with the visual darkroom 1 and is used for adjusting the position of the visual darkroom 1; the controller 3 is in signal connection with the shooting component and is used for receiving the actual measurement image, and a standard image used for comparing with the actual measurement image is stored in the controller 3; and the alarm 4 is in signal connection with the controller 3.
The off-line detection system related to the embodiment of the utility model adopts the visual darkroom 1 to take a picture to obtain the actual measurement image of the part to be measured, then the controller 3 compares the actual measurement image with the pre-stored standard image to further judge whether the part to be measured meets the set requirement, and if not, alarm information can be output externally through the alarm 4 so that a worker can accurately screen out defective products. Compared with the scheme of manual detection in the background technology, the accuracy and the efficiency of the detection of the off-line detection system can be greatly improved.
Moreover, the vision darkroom 1 is adopted for photographing, so that the external interference resistance is stronger, the requirement on the external light condition can be lower, the photographing quality of the measured image can be better ensured, and the positive significance for ensuring the accuracy of the subsequent comparison result is also realized. The specific structure of the vision darkroom 1 and the number and distribution of the light sources therein are not limited, and in practical application, those skilled in the art can determine the structure and distribution according to practical use requirements.
In addition, the embodiment of the present invention does not limit the method for comparing the measured image with the pre-stored standard image after the controller 3 obtains the measured image, and in the specific implementation, a person skilled in the art may also determine the comparison result by combining the prior art, as long as the corresponding technical effect can be ensured. The configuration of the controller 3 can be adjusted as needed, and generally, a PLC controller or the like can be selectively used.
The movable frame 2 is mainly used for adjusting the position of the visual darkroom 1, and the structural design of the movable frame depends on the action requirement of the visual darkroom 1.
In a specific scheme, as also shown in fig. 1, the moving frame 2 may include a horizontal frame body 21 and a vertical frame body 22, the horizontal frame body 21 and the vertical frame body 22 may be connected in a sliding manner in the longitudinal direction, that is, the horizontal frame body 21 may slide longitudinally along the vertical frame body 22 to adjust the longitudinal position of the horizontal frame body 21; the vision darkroom 1 can be installed on the horizontal frame body 21, so that the vision darkroom 1 can synchronously move along with the horizontal frame body 21, and then the longitudinal position of the vision darkroom 1 can be adjusted.
Further, the movable frame 2 may further include a vertical frame body 23, and the vertical frame body 22 may be vertically slidably connected to the vertical frame body 23, so that the vertical positions of the vertical frame body 22 and the visual darkroom 1 mounted thereon may be adjusted, and the focusing requirement of the shooting component may be satisfied.
The moving frame 2 of the utility model can realize displacement adjustment of the visual darkroom 1 in four degrees of freedom in the longitudinal direction and the vertical direction. If necessary, the vision darkroom 1 can be arranged to be capable of performing transverse displacement along the transverse frame body 21, and the movable frame 2 can realize displacement adjustment with six degrees of freedom.
It should be noted that the terms indicating the orientation and the positional relationship, such as the horizontal direction, the vertical direction, and the vertical direction, are all based on the orientation and the positional relationship in fig. 1.
The displacement adjustment of each frame body on the movable frame 2 can be manually controlled by workers or automatically controlled.
In the embodiment of the present invention, an automatic control scheme is preferably adopted to further improve the automation degree of the equipment. At this time, the offline detection system may further include a driving assembly, and the driving assembly is configured to drive the vertical frame body 22 and the horizontal frame body 21 to move. The driving assembly can be in signal connection with the controller 3, that is, a driving control command can be issued by the controller 3 and then executed by the driving assembly to finally adjust the position of the visual darkroom 1 in use.
The number and specific structure of the driving components are not limited herein. Because the action form required by each frame body is linear displacement, the driving assembly can adopt parts such as an air cylinder, a hydraulic oil cylinder and the like which can directly output the linear displacement, or the driving assembly can also adopt a structural form of a motor and a displacement conversion mechanism, and the displacement conversion mechanism can be a gear rack mechanism, a screw rod mechanism and the like which can convert the rotary displacement into the linear displacement.
Further, an inspection platform 5 may be further included for mounting the component to be inspected. The structural form of the detection platform 5 can be designed according to the structural form of the component to be detected, and if the component to be detected is a structural component which is not easy to fix and place, such as a non-flat plate structure, a certain number of positioning components can be configured on the detection platform 5 to position and assemble the component to be detected.
The type of the alarm 4 can be adjusted according to the needs, and the common audible and visual alarm, audible alarm (such as buzzer alarm), optical alarm and the like can be adopted.
The part to be detected can be specifically a welding spot part, and at the moment, the off-line detection system detects whether the quantity, the size and the like of the welding spots meet the requirements or not. In addition, the part to be tested may also be a part with an accessory, and at this time, the offline detection system detects whether a corresponding accessory is installed on a corresponding part of the component to be tested.
Taking the detection of the rear floor of a certain vehicle as an example, the size of the rear floor is 1400mm by 720mm, 142 detection points exist in total, when the off-line detection system provided by the utility model is used for detection, the vision darkroom 1 can be provided with four cameras for image taking, and the detection period is only 20 s; to accomplish the same detection task, at least 4 employees are required to work at the same time for 60s if the scheme in the background art is adopted. Therefore, after the off-line detection system provided by the utility model is adopted, the detection efficiency can be greatly improved, the defect distinguishing rate can basically reach 100%, and the accuracy can also be greatly improved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
