Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to an automated optical detection system for a master mold. Background Art

[0002] In the production process of the screen, the LIPO production process is usually used. The LIPO process is an advanced screen packaging technology. The LIPO process significantly compresses the width of the screen border and increases the screen-to-body ratio by optimizing the display driver chip and circuit layout, thereby bringing a more extreme visual experience. The LIPO technology greatly reduces the space required for the border by folding or hiding the driver chip to the back of the screen. ‌ In the process of producing screens using the LIPO process, a mother mold for holding the screen is used. The mother mold contains a rubber ring that is glued to the screen. During the production process, the mother mold is usually inspected. In order to prevent the mother mold from affecting the screen, defects such as foreign matter, scratches, dirt, cracks, and residual glue are inspected on the mother mold. The mother mold is also inspected for residual glue, excess glue, and blockage. During the inspection of the mother mold transfer, the mother mold is usually directly grabbed by a gripper and placed on a transfer table. The gripper directly placing the mother mold can easily cause a hard collision with the transfer table when the mother mold falls on the transfer table, which can easily cause damage to the mother mold, and there is a lack of a device to buffer the mother mold. Summary of the invention

[0003] In order to improve the convenience of the automated optical inspection system for master molds during operation, the present application provides an automated optical inspection system for master molds.

[0004] This application provides an automated optical detection system for a master mold, which adopts the following technical solutions: The automated optical detection system of a master mold comprises a chassis, on which a transport device and a transfer device for transporting the master mold are installed, the transfer device comprises a transfer frame, the transfer frame is installed on the chassis, a transfer platform is arranged on the transfer frame, a receiving component for receiving the master mold is installed on the transfer platform, the receiving component comprises a first slide rail, the first slide rail is installed on the transfer platform, a guide rod is installed on the first slide rail, a first adjustment block and a second adjustment block are slidably connected to the guide rod, a first spring and a second spring are sleeved on the guide rod, the first spring is arranged on a side of the first adjustment block away from the second adjustment block, the second spring is arranged on a side of the second adjustment block away from the first adjustment block, a first connecting rod is hinged on the first adjustment block, a second connecting rod is hinged on the second adjustment block, a lifting rod is slidably connected to the transfer platform, the first connecting rod and the second connecting rod are both hinged to the lifting rod, a receiving plate for receiving the master mold is installed on the lifting rod, and a first detection component and a second detection component for detecting the master mold are installed on the chassis.

[0005] By adopting the above technical solution, the mother mold is placed on the transportation device and transported by the second device, and is transferred to the detection position by the transfer device. When the mother mold is placed on the receiving plate, the mother mold will press the receiving plate and the lifting rod, and the lifting rod will push the first adjustment block and the second adjustment block to slide away from each other on the guide rod. The first adjustment block and the second adjustment block will both press the spring to achieve a buffering effect, which is convenient for the transfer and stop of the mother mold to reduce the damage caused by collision of the mother mold during the transfer process. During the transfer process, the detection of the mother mold is completed by the first detection component and the second detection component, which is beneficial to improve the efficiency of the automated optical detection system of the mother mold during use.

[0043] Reference Figure 6 and Figure 7 A limit assembly 36 for controlling the displacement of the first adjusting block 343 and the second adjusting block 344 is installed on the transfer platform 331. Figure 7 The limiting assembly 36 shown as being connected to the second adjustment block 344 includes a second slide rail 361, which is fixedly mounted on the transfer platform 331, and is arranged parallel to the first slide rail 341. A moving block 362 is slidably mounted on the second slide rail 361, a mounting rod 363 is fixedly mounted on the moving block 362, a turntable 364 is rotatably mounted on the mounting rod 363, a movable notch 364 is provided on the turntable 364, a stopper 365 is fixedly mounted on the moving block 362, and one end of the stopper 365 extends into the movable notch 3641. A stopper 366 is fixedly mounted on the turntable 364, and a first stopper 367 and a second stopper 368 for moving the stopper 366 are fixedly mounted on the second slide rail 361, and the first stopper 367 and the second stopper 368 are arranged at intervals. A third connecting rod 369 is fixedly mounted on the mounting rod 363 , and one end of the third connecting rod 369 away from the mounting rod 363 is fixedly connected to the second adjustment block 344 .

[0044] Reference Figure 5 , Figure 6 and Figure 7 When the receiving plate 35 is not provided with a master mold, the first spring 345 pushes the first adjusting block 343, and the second spring 346 pushes the second adjusting block 344 so that the first adjusting block 343 and the second adjusting block 344 move closer to each other, the first adjusting block 343 drives the first connecting rod 348 to move, and the second adjusting block 344 drives the second connecting rod 349 to move, and the first connecting rod 348 and the second connecting rod 349 jointly support the lifting rod 347 and the receiving plate 35. When the first adjusting block 343 and the second adjusting block 344 move closer to each other, as shown in FIG. Figure 7 The second adjustment block 344 and the limit assembly 36 are shown. The second adjustment block 344 drives the third connecting rod 369 to move, and the third connecting rod 369 drives the mounting rod 363 and the moving block 362 to slide in the direction close to the first blocking rod 367. When the blocking piece 366 contacts the first blocking rod 367, the blocking piece 366 will drive the turntable 364 to rotate. When the side wall of the turntable 364 rotates to abut against the blocking piece 365, the moving block 362 can be quickly limited to stop the moving block 362 from moving, thereby controlling the second adjustment block 344 to stop moving through the third connecting rod 369. When the second adjustment block 344 stops moving, the receiving plate 35 stops lifting, so as to quickly stop each receiving plate 35 at the same height to wait for receiving the mother mold, which is conducive to the stable placement of the mother mold.

[0045] When the mother mold is placed on the receiving plate 35, the mother mold will press the receiving plate 35 and the lifting rod 347, and the lifting rod 347 will push the first adjustment block 343 and the second adjustment block 344 to slide away from each other on the guide rod 342. The first adjustment block 343 and the second adjustment block 344 will both press the spring to achieve a buffering effect. Figure 7 When the second stopper 364 is in contact with the second stopper 368, the second stopper 368 will move the stopper 366 and the turntable 364 to rotate. When the turntable 364 rotates to the vertical side wall on the other side of the movable notch 3641 and abuts against the stopper 365, the moving block 362 reaches the maximum displacement and stops moving. The second adjusting block 344 also stops moving, and the receiving plate 35 reaches the maximum displacement of the decline. The second stopper 368 cooperates with the turntable 364 to quickly limit the moving block 362, so that the descending height of the receiving plate 35 can be quickly determined and stopped, so that each receiving plate 35 can stay at the same height, avoiding the problem of inconsistent descending height of the receiving plate 35 due to different spring elasticity or spring fatigue.

The fourth cylinder 54 controls the lifting and lowering of the third lifting plate 55 to determine the shooting range, and the light 53 is used to provide fill light to increase the clarity of the shooting, so as to quickly complete the inspection of the mother mold.

[0053] The implementation principle of the embodiment of the present application is as follows: the mother mold is placed on the carrier 24 of the transport device 2, and the first motor 23 controls the conveyor belt 22 to transport the mother mold. During the transportation process, the first clamping claw cylinder 324 grabs the mother mold and places it on the transfer platform 331, and receives it through the elastic receiving component 34, so that the mother mold is transported smoothly and safely during the transportation process, the collision of the mother mold during the transportation process is reduced, and the protection performance of the mother mold is enhanced. The mother mold on the transfer platform 331 is transported to the first detection component 4 through the lifting plate 374, and the first camera 42 and the camera 43 complete the information collection of the mother mold, and detect foreign matter, scratches, dirt, cracks, residual glue and other defects on the mother mold. After the detection is completed, the second clamping claw cylinder 386 continues to grab the mother mold and transport it to the first transport rack 21. During the transportation process, it passes above the second detection component 5, and the second camera 52 collects image information to detect whether there is residual glue, excess glue and blockage in the rubber sleeve in the mother mold. Finally, it is re-placed on the carrier 24 of the first transport rack 21 and transported to the next process.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
