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] The LIPO production process is often used in the production of screens. 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 folds or hides the driver chip to the back of the screen, significantly reducing the space required for the border.

[0003] During the production of screens using the LIPO process, a mother mold for holding the screen is used. A rubber ring that fits the screen is glued inside the mother mold. 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 in the rubber sleeve. 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 thus there is a lack of a device to cushion the mother mold. Summary of the Invention

[0004] In order to improve the convenience of the automated optical detection system for the master mold during operation, the present application provides an automated optical detection system for the master mold.

[0005] This application provides an automated optical detection system for master molds, which adopts the following technical solutions:

[0006] The automated optical inspection system of a master mold comprises a chassis, wherein a transport device and a transfer device for transporting the master mold are installed on the chassis, the transfer device comprises a transfer frame, the transfer frame is installed on the chassis, a transfer platform is provided on the transfer frame, a receiving assembly for receiving the master mold is installed on the transfer platform, the receiving assembly 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 adjusting block and a second adjusting 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 the side of the first adjusting block away from the second adjusting block, the second spring is arranged on the side of the second adjusting block away from the first adjusting block, a first connecting rod is hinged on the first adjusting block, a second connecting rod is hinged on the second adjusting 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 assembly and a second detection assembly for detecting the master mold are installed on the chassis.

[0007] 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 transportation and stop of the mother mold to reduce the damage caused by collision of the mother mold during transportation. During transportation, the detection of the mother mold is completed by the first detection component and the second detection component, which is beneficial to improving the efficiency of the automated optical detection system of the mother mold during use.

[0008] In a specific feasible implementation scheme, a limiting assembly for controlling the movement displacement of the first adjusting block and the second adjusting block is installed on the transfer platform, and the limiting assembly includes a second slide rail, the second slide rail is installed on the transfer platform, and a moving block is slidably installed on the second slide rail, and the moving block is installed with a mounting rod, and a turntable is rotatably installed on the mounting rod, and a movable notch is opened on the turntable, and a stopper is installed on the moving block, and one end of the stopper extends into the movable notch, and a stop plate is installed on the turntable, and a first stop rod and a second stop rod are installed on the second slide rail to block the stop plate, and the first stop rod and the second stop rod are spaced apart, driving a third connecting rod to be installed on the mounting rod, and the end of the third connection away from the mounting rod is connected to the first adjusting block or the second adjusting block.

[0009] By adopting the above technical solution, when the receiving plate has not placed the mother mold on it, the first adjusting block and the second adjusting block move closer to each other and jointly support the lifting rod and the receiving plate. When the first adjusting block and the second adjusting block move closer to each other, the third connecting rod will be driven to move, and the third connection will drive the mounting rod and the moving block to slide in the direction close to the first baffle. When the baffle contacts the first baffle, the baffle will drive the turntable to rotate. When the side wall of the turntable rotates to contact the baffle, the moving block can be quickly limited to stop the moving block, thereby controlling the first adjusting block and the second adjusting block to stop moving through the third connecting rod, so that the receiving plate stops lifting, thereby facilitating the rapid stop of each receiving plate at the same height to wait for the receiving mother mold, which is conducive to the stable placement of the mother mold.

[0010] When the master mold is placed on the receiving plate, the master mold will press the receiving plate and the lifting rod, and the lifting rod will push the first adjusting block and the second adjusting block to slide away from each other on the guide rod, and the third connecting rod controls the moving block to slide on the second slide rail in the direction close to the second blocking rod. When the blocking piece contacts the second blocking rod, the second blocking rod will toggle the blocking piece and the turntable to rotate. When the turntable rotates to the vertical side wall on the other side of the movable notch against the blocking piece, the moving block reaches the maximum displacement and stops moving, and the receiving plate reaches the maximum displacement of the lowering. The second blocking rod cooperates with the turntable to quickly limit the moving block, so as to quickly determine the lowering height of the receiving plate and stop it, so that each receiving plate can stay at the same height, avoiding the problem of inconsistent lowering height of the receiving plate due to different elasticity of the spring or fatigue of the spring. The receiving plates stay at the same height so that the master mold can be placed horizontally, which is convenient for the transfer of subsequent processing processes.

[0016] By adopting the above technical solution, the movement of the lifting plate is controlled by the second electric slide and the second cylinder, so that the mother mold can be quickly lifted from the transfer platform and transferred.

[0017] In a specific possible implementation scheme, the transfer device also includes a third mounting bracket, which is mounted on the chassis, and a third electric slide is mounted on the third mounting bracket, and a third slider is connected to the third electric slide, and a third cylinder is mounted on the third slider, and the output shaft of the third cylinder is connected to a second lifting plate, and a second clamping cylinder for transporting the master mold from the transfer platform to the transport device is mounted on the second lifting plate.

[0018] By adopting the above technical solution, the third cylinder of the third electric slide controls the movement of the second clamping cylinder, which facilitates the rapid grasping of the master mold.

[0019] In a specific possible implementation scheme, the first detection component includes a second mounting bracket, the second mounting bracket is mounted on the chassis, and the first camera and the camera head for collecting image information are mounted on the second mounting bracket.

When the blocking piece contacts the first blocking rod, the blocking piece will drive the turntable to rotate. When the side wall of the turntable rotates to abut against the blocking piece, the moving block can be quickly limited to stop the moving block, thereby controlling the first adjusting block and the second adjusting block to stop moving through the third connecting rod, so that the receiving plate stops lifting, thereby facilitating the rapid stop of each receiving plate at the same height to wait for the receiving master mold, which is conducive to the stable placement of the master mold.

When the blocking piece contacts the second blocking rod, the second blocking rod will toggle the blocking piece and the turntable to rotate. When the turntable rotates to the vertical side wall on the other side of the movable notch against the blocking piece, the moving block reaches the maximum displacement and stops moving, and the receiving plate reaches the maximum displacement of the lowering. The second blocking rod cooperates with the turntable to quickly limit the moving block, so as to quickly determine the lowering height of the receiving plate and stop it, so that each receiving plate can stay at the same height, avoiding the problem of inconsistent lowering height of the receiving plate due to different elasticity of the spring or fatigue of the spring. The receiving plates stay at the same height so that the master mold can be placed horizontally, which is convenient for the transfer of subsequent processing processes.

[0046] Reference Figure 6 and Figure 7 The transfer platform 331 is provided with a limit assembly 36 for controlling the displacement of the first adjustment block 343 and the second adjustment block 344. Figure 7The limiting assembly 36 shown is connected to the second adjustment block 344. The limiting assembly 36 includes a second slide rail 361, which is fixedly mounted on the transfer platform 331 and arranged parallel to the first slide rail 341. A moving block 362 is slidably mounted on the second slide rail 361, and a mounting rod 363 is fixedly mounted on the moving block 362. A turntable 364 is rotatably mounted on the mounting rod 363. The turntable 364 has a movable notch 3641. 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. A first stopper 367 and a second stopper 368 are fixedly mounted on the second slide rail 361 to move the stopper 366. The first stopper 367 and the second stopper 368 are spaced apart. 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 .

[0047] Reference Figure 5 、 Figure 6 and Figure 7 When the mother mold is not placed on the receiving plate 35, the first spring 345 will push the first adjusting block 343, and the second spring 346 will push 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 will drive the first connecting rod 348 to move, and the second adjusting block 344 will drive the second connecting rod 349 to move. The first connecting rod 348 and the second connecting rod 349 will 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. The movement of the moving block 362 is thereby controlled to stop by the third connecting rod 369. When the second adjustment block 344 stops moving, the receiving plate 35 stops rising and falling, thereby facilitating the rapid stop of each receiving plate 35 at the same height to wait for the receiving mother mold, which is conducive to the stable placement of the mother mold.

[0048] 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. 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 press the spring to achieve a buffering effect. Figure 7When the second stopper 366 contacts the second stopper 368, the second stopper 368 will toggle the stopper 366 and the rotary plate 364 to rotate. When the rotary plate 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, and the second adjusting block 344 also stops moving, and the receiving plate 35 reaches the maximum displacement of the lowering. The second stopper 368 cooperates with the rotary plate 364 to quickly limit the moving block 362, so as to quickly determine the lowering height of the receiving plate 35 and stop it, so that each receiving plate 35 can stay at the same height, avoiding the problem of inconsistent lowering heights of the receiving plates 35 due to different spring elasticity or spring fatigue. The receiving plates 35 stay at the same height so that the mother mold can be placed horizontally, which is convenient for the transfer of subsequent processing.

[0050] When the mother mold on the transfer table 331 needs to be transferred, the second electric slide 371 is used to control the lifting plate 374 to move to the bottom of the mother mold, the second cylinder 373 controls the lifting plate 374 to lift the mother mold, and then the second electric slide 371 is used to control the lifting plate 374 to move, so as to quickly transfer the mother mold.

The second mounting bracket 41 is installed in the middle position of the transportation direction of the transfer rack 33. The first camera 42 and the camera head 43 for shooting are fixedly mounted on the second mounting bracket 41. The first camera 42 and the camera head 43 are both arranged above the transfer platform 331.

[0052] When the transfer master mold moves the master mold to the position of the first detection component 4, the first camera 42 and the camera 43 complete the information collection of the master mold, and detect defects such as foreign matter, scratches, dirt, cracks, and residual glue on the master mold. Information collection facilitates rapid identification of abnormal products on the master mold during the production process.

[0053] Reference Figure 8 and Figure 9The transfer device 3 also includes a third mounting frame 381, which is fixedly mounted on the chassis 1, and a third electric slide 382 is fixedly mounted on the third mounting frame 381. The third electric slide 382 is arranged above the transfer platform 331 and the first transport frame 21, and a third slider 383 is connected to the third electric slide 382.

The third lifting plate 55 is provided with a camera hole 551 for locking the shooting area.

[0055] When the inspection of the first inspection component 4 is completed, the third electric slide 382 controls the second clamping cylinder 386 to move horizontally, and the third cylinder 384 controls the second clamping cylinder 386 to move vertically to grab the mother mold and transport it to the top of the second inspection component 5. The second camera 52 is used to collect image information to detect whether there is residual glue, excess glue and blockage in the rubber sleeve in the mother mold, and 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 fill in the light to increase the clarity of the shooting, so as to quickly complete the inspection of the mother mold.

[0056] The working 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 cylinder 324 grabs the mother mold and places it on the transfer platform 331. The elastic supporting component 34 supports the mother mold, so that the mother mold is transported smoothly and safely during the transportation process, reducing the collision of the mother mold during the transportation process and enhancing the protection performance of the mother mold. The mother mold on the transfer platform 331 is transported to the first inspection component 4 by the lifting plate 374. The first camera 42 and the camera 43 complete the information collection of the mother mold and detect defects such as foreign matter, scratches, dirt, cracks, and residual glue on the mother mold. After the inspection is completed, the second clamping 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 inspection 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. Finally, it is placed back on the carrier 24 of the first transport rack 21 and transported to the next process.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
