Description

Technical Field

[0001] The invention relates to the technical field of material sampling, in particular to an automatic sampling device for automobile parts. Background Art

[0002] During the production process of auto parts, it is often necessary to collect some finished products from the production line to analyze whether the product quality meets the standards. Sampling and testing can help companies to promptly discover problems in the production process, such as unstable production processes and equipment failures. Companies can take corresponding measures to adjust and improve them accordingly. At the same time, through regular sampling and testing of auto parts, companies can promptly discover potential problems and solve them to prevent small problems from turning into major failures. This not only extends the service life of the car, but also significantly saves maintenance costs, thereby adjusting the production line and achieving the goal of improving product quality.

[0003] When grasping and inspecting automotive parts, suction cups are often used to secure smooth, flat, and rigid parts, such as body panels (e.g., doors and hoods), glass components (e.g., windshields and windows), and some interior trim. While this can reduce the risk of surface damage, it requires a firm pressure to ensure complete contact with the surface. This can easily cause the part to slip, as the vertical downward pressure generated by the suction cup exceeds the maximum static friction between the part and the conveyor belt. This can compromise the accuracy and stability of the grasping process. Furthermore, the conveyor belt (made of rubber) can dent when the suction cup is pressed against the part, and then elastically recovers after the pressure is released. This can cause other parts on the conveyor belt to "bounce," impacting the stability of the conveyor belt. To address this issue, we propose an automatic sampling device for automotive parts.

It should be noted here that the push rod motor 1107 is provided to push each push rod 1105 .

[0030] In this solution: an automatic sampling device for automobile parts, comprising the following steps: During the sampling and testing of automobile parts, when the processed automobile parts are conveyed by the respective conveyor belts 1003 on the support 102, when the automobile parts are conveyed to the side of the respective push rods 1105, the push rod motors 1107 are started to push the push blocks 1106 at one end of the respective push rods 1105 against the surface of the automobile parts, thereby separating the automobile parts from the surface of the conveyor belts 1003 during the continuous pushing process; After the automobile part is separated from the surface of the conveyor belt 1003, the industrial robot 201 pushes the fixed frame 204 at one end of the operating rod 202 to move closer to the automobile part (when inspecting and sampling automobile parts, the industrial robot 201 can pre-drive the fixed frame 204 to face the pushing rod 1105, and only maintain a distance within which the automobile part can move safely, thereby enabling rapid sampling of automobile parts). In the process of the fixed frame 204 moving closer to the automobile part, the suction cup 206 at one end of the adjusting tube 404 will be synchronously driven to move. When the suction cup 206 abuts against the surface of the automobile part, if there is an inclined surface at the abutment point, the suction cup 206 will adaptively rotate under the push of the industrial robot 201 and the pressing force against the surface of the automobile part, thereby making the center line of the suction cup 206 perpendicular to the inclined surface of the automobile part, thereby ensuring sufficient abutment between the suction cup 206 and the surface of the automobile part. In addition, during the process of the suction cup 206 abutting against the surface of the automobile part, the automobile part is pushed to the side away from the conveyor belt 1003 by each pushing block 1106. Therefore, during the process of the suction cup 206 abutting against the surface of the automobile part, it can provide a rigid support for the abutment between the suction cup 206 and the automobile part, thereby reducing the sliding friction of the automobile part during the abutment process. At the same time, it can also avoid the risk of other automobile parts "bouncing" due to the elastic force generated by the extrusion and deformation of the conveyor belt 1003. Therefore, while improving the grasping accuracy and stability in the process of sampling automobile parts, it ensures the stability of the conveyor belt 1003 in conveying automobile parts. After the suction cup 206 is fully in contact with the surface of the auto part, the vacuum air pump can be started to extract the air from the suction cup 206 through the connecting hose, the air pipe 301 and the bellows 302, thereby placing the suction cup 206 in a vacuum state. As a result, under the action of the air pressure difference, the suction cup 206 can adsorb and fix the auto part. At the same time as the suction cup 206 is vacuum-adsorbing and fixing the auto part, the air in the locking tube 502 will be synchronously extracted through the mounting tube 505. At this time, under the guidance of the vacuum adsorption and the limit assembly, the locking tube 502 will be locked. The extrusion plate 601 in the tube 502 moves close to the mounting tube 505, thereby driving the locking rod 503 to move, so that the wedge-shaped groove 504 on the surface of the locking rod 503 abuts against the surface of the rotating shaft 402. As a result, under the action of the wedge-shaped abutment, the rotating shaft 402 is locked and fixed, and the suction cup 206 that has been adjusted in rotation is locked and fixed through the adjustment tube 404, thereby avoiding the stress concentration problem at the connection point caused by the rotation connection between the suction cup 206 and the sliding plate 205, thereby ensuring stability during the process of pulling the automobile parts upward.
