During the display screen burning test process, a material taking device is required for loading and unloading to replace the heavy labor of people to achieve the mechanization and automation of production.

[0003] Chinese Patent Grant Publication No.: CN216014773U discloses an automatic burning test device for display screens.

[0004] In the above solution, the loading and unloading of the display screen in the FOG burning test are realized by setting a robotic arm and a material grabbing component. Since the display screen part and the FPC part are connected through encapsulation, in the above solution, relevant detection cannot be performed on the display screen during the loading process, which easily causes display screens with poor connection stability to flow into the production process, increasing subsequent production costs and potential quality risks.

[0005] Therefore, it is necessary to provide a material taking device for detecting FOG burning to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Utility Model Content

Through the mutual cooperation of the loading robotic arm and the material grabbing component, it is possible to control the small-amplitude vibration of the vibrating plate in the vertical direction during the loading process of the display screen, thereby detecting the display screen and judging the connection stability between the circuit board and the glass in the display screen. When the circuit board and the glass are separated, the display screen is moved to the unqualified area. By timely detecting and excluding the display screens with unstable connections, it can be ensured that only qualified display screens enter the subsequent production process, which helps to improve product quality, reduce the generation of defective products, and improve the reliability of the final product.

[0010] Further, the guiding rod penetrates through the connecting plate and is slidably connected to the connecting plate.

[0012] Further, the material grasping component further includes a plurality of first springs. Two ends of the plurality of first springs are respectively fixedly connected to the vibrating plate and the mounting plate.

Specific embodiments

[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] As Figures 1-4 shown, the present application provides a material taking device for detecting FOG burning, including a mounting base 1, a loading robot arm 2 and an unloading assembly 3 are respectively installed at the top end of the mounting base 1, and a material grasping assembly 4 is installed at the end of the loading robot arm 2;

[0028] The material grabbing assembly 4 includes a connecting plate 41 and a vibrating plate 42. The connecting plate 41 can be connected to the end of the loading robotic arm 2 by bolts. The vibrating plate 42 is located below the connecting plate 41, and an installation plate 43 is installed at the bottom of the vibrating plate 42. A plurality of vacuum suction cups 44 are installed at the bottom end of the installation plate 43. A vibrating member 46 is provided at the bottom end of the connecting plate 41. A guide rod 48 is installed at the top of the vibrating plate 42. The guide rod 48 can be fixed to the top of the vibrating plate 42 by welding. A second spring 47 is sleeved outside the guide rod 48. Both ends of the second spring 47 can be fixedly connected to the connecting plate 41 and the end of the second spring 47. The vibrating member 46 includes a motor 461 installed at the bottom of the connecting plate 41. The motor 461 can be fixed to the bottom of the connecting plate 41 by bolts. A cam 462 is installed at the output end of the motor 461.

[0029] This solution is used for picking up the display screen during the burning test of the display screen after FOG binding, replacing the heavy labor of people to achieve the mechanization and automation of production. The picking operation includes loading and unloading operations. Among them, the loading operation uses the loading robotic arm 2 and the material grabbing assembly 4 to move the display screen to be tested on the loading transfer platform to the detection station for burning test to determine whether the display screen is qualified. The unloading operation is to move the tested display screen from the detection station to the unloading transfer platform through the unloading assembly 3.

[0030] Specifically, during the loading process, the material grabbing assembly 4 is moved to the loading transfer platform by using the loading robotic arm 2, and the display screen to be tested is adsorbed by the vacuum suction cups 44. Then, the material grabbing assembly 4 is moved to the detection station by the loading robotic arm 2. During this process, the motor 461 can be started to control the cam 462 to rotate. The cam 462 squeezes the vibrating plate 42, causing the guide rod 48 on one side of the vibrating plate 42 to displace, and the guide rod 48 simultaneously compresses the second spring 47. As the cam 462 continues to rotate, a small amplitude vibration of the vibrating plate 42 in the vertical direction is realized, so as to detect the display screen and judge the connection stability between the circuit board and the glass in the display screen. When the circuit board and the glass are separated, the display screen is moved to the unqualified area. By detecting and eliminating the display screen with unstable connection in time, it can ensure that only qualified display screens enter the subsequent production process, which helps to improve the product quality, reduce the generation of defective products, and improve the reliability of the final product. During the unloading process, the tested display screen is moved from the detection station to the unloading transfer platform through the unloading assembly 3.

[0031] Among them, the unloading assembly 3 includes an unloading robotic arm and a suction cup assembly connected to the unloading robotic arm, which uses vacuum to adsorb and transfer the tested display screen.

[0032] It should be noted that the vibration frequency of the display screen can be controlled by adjusting the rotation speed of the motor 461, and the vibration duration of the display screen can be controlled by adjusting the start and stop time of the motor 461.

[0033] As Figures 3-4 shown, the guide rod 48 penetrates through the connecting plate 41 and is slidably connected to the connecting plate 41.

[0034] In this embodiment, the arranged guide rod 48 can play a guiding role in the movement of the vibrating plate 42, improving the vibration stability of the vibrating plate 42.

[0035] As Figures 1-4 shown, the connecting plate 41, the vibrating plate 42 and the mounting plate 43 are all arranged in parallel, ensuring the stability during the process of picking up the display screen.

[0036] As Figures 3-4 shown, the material grasping assembly 4 further includes a plurality of first springs 45, and both ends of the plurality of first springs 45 are fixedly connected to the vibrating plate 42 and the mounting plate 43 respectively.

[0037] In this embodiment, the first spring 45 cooperates with the vibrating member 46, enabling the vibration detection of the display screen, and the arranged first spring 45 can play a buffering role, avoiding the problem that the excessive force of the feeding robotic arm 2 on the display screen during the picking process causes damage to the screen.

[0038] As Figure 4 shown, an installation groove is formed at the top of the vibrating plate 42, and a roller 410 is rotatably connected to the inner wall of the installation groove, and the roller 410 abuts against the cam 462.

[0039] In this embodiment, the arranged roller 410 can cooperate with the cam 462, reducing the friction between the cam 462 and the vibrating plate 42, which is beneficial to the vibration detection of the display screen.

[0040] As Figure 4 shown, the material grasping assembly 4 further includes a detection head 49, and the detection head 49 is installed at the bottom of the mounting plate 43.

[0041] In this embodiment, the arranged detection head 49 can monitor the connection part between the display screen part and the FPC part in the display screen, judge whether there is separation. When the circuit board is separated from the glass, it means that the display screen is unqualified, and then the feeding robotic arm 2 is used to move the display screen to the unqualified area.

[0042] Among them, the detection head 49 can be a camera or an optical sensor, which is used to monitor whether the circuit board and the glass in the display screen are separated.

[0043] Working principle:

[0044] By using the loading robotic arm 2 to move the material-gripping assembly 4 to the loading transfer platform, and adsorbing the display screen to be tested through the vacuum suction cup 44, and then using the loading robotic arm 2 to move the material-gripping assembly 4 to the detection station. During this process, the motor 461 can be started to control the rotation of the cam 462. The cam 462 squeezes the vibrating plate 42, causing the displacement of the guide rod 48 on one side of the vibrating plate 42. The guide rod 48 simultaneously compresses the second spring 47. As the cam 462 continues to rotate, a small-amplitude vibration of the vibrating plate 42 in the vertical direction is achieved, thereby detecting the display screen and judging the connection stability between the circuit board and the glass in the display screen. When the circuit board and the glass are separated, the display screen is moved to the unqualified area to prevent the display screen with poor connection stability from flowing into the subsequent production process. During the unloading process, the tested display screen is moved from the detection station to the unloading transfer platform through the unloading assembly 3.

[0045] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
