Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone production and manufacturing, and in particular to a visual inspection device and an inspection method based on a work island type assembly production line. Background Art

[0002] The island assembly line is an efficient production layout design, which is often used in the product assembly process. This layout usually arranges equipment and workstations into a ring-shaped, island-like configuration, which has many advantages, especially in terms of flexibility and production efficiency. The island assembly line is widely used in industries such as electronic products, automobiles, home appliances, and mechanical equipment, especially in production environments with high requirements for flexibility and efficiency. In the production process of mobile phones, the motherboard module, battery module, and camera module in the mobile phone need to be installed in the mobile phone shell in sequence through the island assembly line. After the installation is completed, in order to ensure that the battery, camera, and motherboard are installed in the correct position without misalignment or deviation, they need to be inspected by a visual inspection device. The traditional inspection method is a frontal top-view inspection, but most of the modules in the mobile phone are convex blocks, and the convex parts sometimes block some details and cause inspection loopholes. The top-view inspection cannot intuitively detect whether the gap between the module and the mobile phone shell is uniform, thereby affecting the production quality of the mobile phone. Secondly, when the staff manually loads and unloads the mobile phone shell, this will reduce production efficiency and increase the possibility of human error. In view of the above problems, the inventor proposes a visual inspection device and inspection method based on a working island assembly line to solve the above problems. Summary of the invention

[0032] A detection method used by a visual inspection device based on a work island assembly production line comprises the following steps: S1. First, the mobile phone housing to be assembled is moved from the feeding conveyor belt 9 to the rotating frame 307 by the automatic feeding and unloading assembly 7, and the mobile phone housing is positioned and fixed by the centripetal positioning device in the rotating frame 307; S2. The movable frame 306 is driven to rotate intermittently through the station synchronous intermittent conveying assembly 3 and sequentially passes through three assembly workstations, and the motherboard module, battery module and camera module are installed in the mobile phone housing through three assembly stations; S3. After the internal module of the mobile phone housing is installed, it moves to the detection camera 4, and detects the installation connection of the internal module of the mobile phone housing through visual sensing. During the detection, the mobile phone housing is tilted once and reset after the station tilt adjustment component 5 is driven to tilt the mobile phone housing left and right, and the installation connection of the internal module of the mobile phone housing is detected from multiple angles; S4. After the detection is completed, the mobile phone shell moves to the automatic loading and unloading assembly 7, and the automatic loading and unloading assembly 7 transfers the mobile phone shell after the detection and installation to the unloading conveyor belt 10 while moving the mobile phone shell in the loading conveyor belt 9 to the rotating frame 307.

[0033] Working principle: First, control the driving end of motor 715 to rotate clockwise for one circle. Figure 7 As shown, during this process, the first motor 715 rotates one circle through the second rotating rod 716 and the guide frame 717 to drive the rack 714 to move to the right to the rightmost end, then to the left to the leftmost end, and then continue to move to the right to reset, as shown in FIG. Figure 6 As shown, during this process, the rack 714 drives the swing frame 704 to swing to the right first by rotating the gear 713 and the rotating shaft 703, and the swing frame 704 drives the fixed rod 710 to move to the right first and then descend under the action of the slider 705, the lifting rod 706, the fixed shaft 707, the guide plate 708 and the guide groove 709, so that the loading electric suction cup 711 contacts and adsorbs the corresponding mobile phone shell in the loading conveyor belt 9, and the unloading electric suction cup 712 contacts and adsorbs the corresponding mobile phone shell in the moving frame 306. In the process of the swing frame 704 swinging to the left, the fixed rod 710 is driven first The mobile phone shell in the loading electric suction cup 711 is transferred to the corresponding moving frame 306 and stops being adsorbed and fixed. The mobile phone shell in the unloading electric suction cup 712 is transferred to the unloading conveyor belt 10 and stops being adsorbed and fixed. Finally, the swing frame 704 swings to the right to reset and drive the fixing rod 710, the loading electric suction cup 711 and the unloading electric suction cup 712 to reset. In this way, the effect of loading and unloading the mobile phone shell at the same time is achieved reciprocatingly. After rotating one circle, the No. 1 motor 715 stops rotating and controls the No. 2 motor 807 to drive the drive shaft 801 to rotate one circle clockwise. Figure 8As shown, the driving shaft 801 drives the half gear 802 to mesh with the No. 1 driven gear 804 first, and drives the No. 1 driven shaft 803 to rotate counterclockwise for one circle through the No. 1 driven gear 804. The No. 1 driven shaft 803 drives the right conveying shaft 301 to rotate clockwise for one quarter of a circle through the No. 2 driving wheel 808 and the No. 2 driven wheel 809. The conveying shaft 301 drives the eight moving frames 306 to move intermittently on the inner slide rail 302 and the outer slide rail 303 through the synchronous wheel 304 and the synchronous belt 305, and thus reciprocates through three assembly workstations. The mainboard module, the battery module and the camera module are respectively installed in the mobile phone housing through the three assembly workstations. During the sliding process of the moving frame 306, as shown in FIG. Fig.10 and Fig.11 As shown, the plugs 603 on both sides of the moving frame 306 squeeze the second return spring 606 through the limit plate 605 under the action of the two guide ring frames 601, so that the two plugs 603 pass through the moving frame 306 and are located at the bottom of the rotating frame 307. The rotating frame 307 is limited by the two plugs 603. When the moving frame 306 moves to the station tilt adjustment component 5, the distance between the two guide ring frames 601 increases. Under the action of the second return spring 606, the plugs 603 are pushed into the inner cavity 602 through the limit plate 605 to stop limiting the rotating frame 307. When the moving frame 306 moves to the corresponding position of the station tilt adjustment component 5, the two guide shafts 512 are located at the top of the flip plate 502. Figure 8 As shown, the half gear 802 continues to rotate after being separated from the first driven gear 804 and meshes with the second driven gear 806, and drives the second driven shaft 805 to rotate four times through the second driven gear 806, as shown in FIG. Figure 4As shown, the second driven shaft 805 drives the transmission shaft 506 to rotate four times through the first bevel gear 509 and the second bevel gear 510. The transmission shaft 506 rotates one circle through the first driving wheel 507 and the first driven wheel 508 to drive the rotating shaft 503 to rotate a quarter of a circle. Therefore, the transmission shaft 506 drives the rotating shaft 503 and the first rotating rod 504 to rotate four times intermittently. When the first rotating rod 504 rotates for the first time, it drives the lifting frame 505 to rise. The lifting frame 505 drives the flip plate 502 to flip upward. The flipping of the flip plate 502 drives the rotating frame 307 to flip synchronously through the two guide shafts 512. After the flipping is completed, the tilted mobile phone shell is During the first side photo detection, when the No. 1 rotating rod 504 rotates for the second time, it drives the lifting frame 505 to reset. At this time, the rotating frame 307 is reset synchronously to perform a front-view photo detection. When the No. 1 rotating rod 504 rotates for the third time, it drives the lifting frame 505 to continue to descend. The lifting frame 505 drives the flip plate 502 to flip downward. According to the same steps as above, the rotating frame 307 is driven to flip synchronously, and a photo detection is performed on the other inclined side of the mobile phone shell. When the No. 1 rotating rod 504 rotates for the fourth time, it drives the flip plate 502 to reset. Through the above operations, the visual inspection effect of the mainboard module, battery module and camera module in the mobile phone shell after installation is achieved reciprocally.
