Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive coating inspection technology in automotive parts production, specifically to a real-time 3D inspection mechanism for adhesive coating. Background Technology
[0002] In automobile manufacturing workshops, the car body is manufactured by welding, riveting, or bonding pre-fabricated parts. To ensure good waterproof performance, adhesive is applied to the welded or riveted joints, achieving a sealed, waterproof, aesthetically pleasing, and corrosion-resistant finish. Furthermore, some structural or exterior parts of the car body require bonding; structural adhesive is sprayed onto specific locations on these parts to ensure good adhesion.
[0003] In the adhesive application process of automotive parts manufacturing, automated adhesive application is generally completed by robotic adhesive application systems, and quality inspection of the adhesive application process is generally carried out by manual sampling. Manual sampling mainly involves using different tools to measure the length, width, thickness, and other external dimensions of the adhesive application pattern, observing whether the adhesive application pattern is even and full, whether there are defects such as broken adhesive, glue accumulation, and obvious adhesive wrinkles, and observing whether the adhesive strip trajectory matches the predetermined weld or bonding position.
[0004] Currently, adhesive application inspection in automotive parts manufacturing mostly involves 3D or 2D inspection after adhesive application. Post-application inspection impacts production cycle time and is a bottleneck process in automotive parts production lines. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a real-time 3D inspection mechanism for adhesive application, which consists of 6 laser generators and 6 industrial cameras. It forms a hexagonal line scan pattern from multiple directions and angles to complete the real-time 3D inspection of adhesive application.
[0006] This utility model is achieved through the following technical solution:
[0007] A real-time 3D inspection mechanism for adhesive application includes a housing. The housing has a reserved component for installing an adhesive application mechanism and a reserved robot installation interface for installing a robot. The housing contains an inspection component, which includes six laser generators and six industrial cameras. The six laser generators and six industrial cameras are evenly distributed on the inner and outer circumferences of the housing.
[0008] More preferably, the housing includes a cover plate, an outer sealing plate, and a supporting base plate. The outer sealing plate surrounds the circumferential edge of the supporting base plate, and the cover plate covers the outer sealing plate. The pre-reserved components for the glue application mechanism and the pre-reserved robot installation interface are both installed on the cover plate.
[0009] More preferably, the detection component further includes a laser mounting block and a laser adjustment block. Six laser mounting blocks are evenly distributed in the inner circumferential direction of the support base plate, and a laser adjustment block is provided on the laser mounting block. The laser generator is mounted on the laser adjustment block.
[0010] In a further preferred embodiment, the detection assembly also includes a camera mounting plate and camera adjustment components. Six camera adjustment components are evenly distributed circumferentially on the outer side of the support base plate. The camera mounting plate is connected to the camera adjustment components, and the industrial camera is mounted on the camera mounting plate.
[0011] More preferably, the camera adjustment component includes two fixed bases, one end of the camera mounting plate is rotatably connected to the two fixed bases, and a lifting component is provided between the two fixed bases at the bottom of the camera mounting plate. The top end of the lifting component is connected to the camera mounting plate and is used to rotate the camera mounting plate to adjust the angle of the industrial camera.
[0012] In a further preferred embodiment, the support base plate is provided with an adhesive applicator at its center for applying adhesive, and the cover plate has a through hole at its center.
[0013] More preferably, the reserved component of the glue application mechanism is a side-standing concave shape, with through holes at both the upper and lower ends for installing and fixing the glue application mechanism.
[0014] The beneficial effects of this utility model are:
[0015] 1) This utility model uses an industrial camera and a laser generator for visual inspection of adhesive application. The camera captures images during the adhesive application process to determine the quality of the adhesive application. At the same time, it uses 6 laser generators and 6 industrial cameras to form a hexagonal line scan pattern from multiple directions and angles to complete the real-time 3D inspection of adhesive application.
[0016] 2) This utility model adjusts the laser generator so that the laser beams of the six laser generators are in a regular hexagon. Then, by adjusting the camera angle, the camera captures the laser beams, forming a hexagonal detection area with a glue applicator reserved in the middle, thus realizing real-time 3D detection of glue application.

Detailed Implementation
[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0023] like Figure 1 and 2 As shown, a real-time 3D inspection mechanism for adhesive application includes a supporting base plate 1, an outer sealing plate 2, a cover plate 3, a pre-installed component for the adhesive application mechanism 4, a pre-installed robot mounting interface 5, and a pipeline connector 6. The outer sealing plate 2 surrounds the circumferential edge of the supporting base plate 1, and the cover plate 3 covers the outer sealing plate 2. An adhesive application mechanism for applying adhesive to automotive parts is installed on the cover plate 3, and a robot is also installed on the cover plate 3 for operating the adhesive application mechanism to apply adhesive to the automotive parts. Both the adhesive application mechanism and the robot adopt conventional equipment and models in the field of automotive parts adhesive application. Correspondingly, the cover plate 3 has a pre-installed component 4 for installing the adhesive application mechanism and a pre-installed robot mounting interface 5 for installing the robot. For example, the pre-installed component 4 for installing the adhesive application mechanism is as follows: Figure 1 As shown, the side-standing concave shape is adopted, and the upper and lower ends of the pre-reserved component 4 of the glue application mechanism have through holes for installing and fixing the glue application mechanism. The pre-reserved robot installation interface 5 for the robot is cylindrical, and the upper and lower ends of the cylindrical have connecting flanges. At the same time, pipeline connectors 6 can also be set on the cover plate 3 for connecting various pipelines.
[0024] A detection assembly is installed within the box-like space enclosed by the cover plate 3, the outer sealing plate 2, and the supporting base plate 1. This assembly is used to inspect automotive parts that are being coated with adhesive. Figure 2As shown, the detection assembly includes a camera mounting plate 7, a camera adjustment component 8, an industrial camera 9, a laser mounting block 10, a laser adjustment block 11, and a laser generator 12. Both the laser generator 12 and the industrial camera 9 are conventional equipment and models in the field. In this embodiment, six laser generators 12 and six industrial cameras 9 are respectively provided, and they correspond one-to-one. Specifically, a glue applicator 13 is reserved in the center of the support base plate 1 for glue application. The cover plate 3 has a through hole in its center. Six laser mounting blocks 10 are evenly distributed circumferentially on the inner side of the support base plate 1, and laser generators 12 are mounted on the laser mounting blocks 10. Six camera mounting plates 7 are evenly distributed circumferentially on the outer side of the support base plate 1, and industrial cameras 9 are mounted on the camera mounting plates 7. Each industrial camera 9's camera is directly facing the beam of a corresponding inner laser generator 12. The laser generator 12 emits a laser beam that hits the glued automotive parts, and the industrial camera 9 takes pictures to acquire images, realizing real-time 3D detection of the glue application.
[0025] Preferably, a laser adjustment block 11 is provided on the laser mounting block 10, and the laser generator 12 is mounted on the laser adjustment block 11. The installation position of the laser generator 12 is finely adjusted by the laser adjustment block 11, so that the beam can be accurately emitted onto the glued automotive parts. Six camera adjustment components 8 are evenly distributed circumferentially on the outer side of the support base plate 1 to adjust the installation angle of the industrial camera 9. For example, the camera adjustment component 8 adopts two fixed bases 14, and one end of the camera mounting plate 7 is rotatably connected to the two fixed bases 14. The fixed base 14 is preferably triangular, with the end closer to the laser generator 12 being higher and the end farther from the laser generator 12 being lower. That is, one side of the fixed base 14 is close to the laser generator 12. The diagonal of the side of the base 14 is away from the laser generator 12. A lifting component (not shown in the figure), such as a cylinder or hydraulic cylinder, is set between the two fixed bases 14 at the bottom of the camera mounting plate 7. The top of the lifting component is connected to the camera mounting plate 7 and is used to rotate the camera mounting plate 7, thereby adjusting the angle of the industrial camera 9 toward the laser generator 12. The angle of the industrial camera 9 is adjusted by the camera adjustment component 8 so that the industrial camera 9 can capture the laser beam. By adjusting the laser generator 12, the beams of the six laser generators 12 are arranged in a regular hexagon. By adjusting the angle of the industrial camera 9, the industrial camera 9 can capture the laser beam, forming a hexagonal detection area, which can accurately and without blind spots complete the real-time detection of the adhesive applied to the automotive parts.
[0026] This invention employs an industrial camera 9 and a laser generator 12 for adhesive coating visual inspection, a non-contact inspection method. The camera captures images of the adhesive coating process, which are then processed and analyzed by a computer to determine the quality of the coating. This device consists of six laser generators 12 and six industrial cameras 9, forming a hexagonal line scan pattern from multiple angles and directions to complete real-time 3D inspection of the adhesive coating.
