[0031] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0032] Reference Figure 1 and Figure 2 The embodiment of the present application provides a screen plate detection device, including a first frame 11 and a second frame 12, the first frame 11 and the second frame 12 are stacked up and down and fixedly connected to each other, and in this embodiment, the first frame 11 is above the second frame 12. One end of the first frame 11 is a loading station, and the other end is an unloading station.

[0033] A two-dimensional mobile platform 2 is fixedly connected to the top surface of the first frame 11, and a detection device 3 is provided on one side of the first frame 11. The detection device 3 is used to detect the screen to determine whether the screen is qualified. A material seat 4 is detachably connected to the two-dimensional mobile platform 2. The material seat 4 is used to place the screen. The two-dimensional mobile platform 2 drives the material seat 4 to move under the detection device 3, thereby realizing the detection of the screen by the detection device 3. In this embodiment, the material seat 4 is slidably connected to the output end of the two-dimensional mobile platform 2 to realize the detachable connection between the material seat 4 and the two-dimensional mobile platform 2.

[0034] The detection device 3 includes a display 31, a microscope 32 and a fill light 33. The microscope 32 is fixed on the top of the two-dimensional mobile platform 2 through a frame, the display 31 is fixed on the frame, and the fill light 33 is fixed on the second frame 12 and irradiates in the direction of the first frame 11. While the two-dimensional mobile platform 2 drives the material holder 4 to move, the microscope 32 identifies and detects the screen and transmits the detection image to the display 31 for display. The staff judges whether the screen is qualified by observing the image on the display 31.

[0035] The material holder 4 includes a transparent cover plate 42 and a transparent base 41. The transparent cover plate 42 is rotatably connected to the transparent base 41, and the cover plate is driven to rotate by a motor. The mesh is placed on the transparent base 41 and the transparent cover plate 42 is covered, and the mesh is fixed. The unloading station is provided with an unloading manipulator 51. When unloading is required, the transparent cover plate 42 is automatically opened, and the unloading manipulator 51 grabs the mesh for unloading; the loading station is provided with a loading manipulator 61. When loading is required, the transparent cover plate 42 is automatically opened, and the loading manipulator 61 places the new mesh on the transparent base 41, and then the transparent cover plate 42 is automatically closed.

[0036] Reference Figure 3 and Figure 4The loading station is provided with a loading rack 6, and the unloading station is provided with an unloading rack 5. The unloading rack 5 is fixedly connected with a first linear guide rail 7, and the first linear guide rail 7 is located above the two-dimensional moving platform 2. A circulation device 8 is arranged between the loading rack 6 and the unloading rack 5. The material holder 4 can slide from the output end of the two-dimensional moving platform 2 to the output end of the first linear guide rail 7, and be transported to the unloading station for unloading through the first linear guide rail 7, and then the material holder 4 after unloading is transported to the loading station for loading through the circulation device 8. After the material holder 4 is loaded, it is transported to the output end of the two-dimensional moving platform 2, and the screen is detected through the cooperation of the two-dimensional moving platform 2 and the detection device 3.

[0037] Furthermore, at least two material seats 4 are provided. When one material seat 4 is in the detection state, the other material seat 4 is in the unloading and loading states, thereby ensuring the continuous progress of the detection and increasing the detection efficiency.

[0038] Specifically, the circulation device 8 includes a unloading slide 81, a loading slide 82 and a second linear guide rail 83. The unloading slide 81 is vertically slidably connected to the unloading rack 5, and the loading slide 82 is vertically slidably connected to the loading rack 6. In this embodiment, the loading slide 82 and the unloading slide 81 are both electrically controlled to slide, for example, the loading slide 82 and the unloading slide 81 are driven to slide by linear guide rails.

[0039] The second linear guide 83 is fixedly connected to the second frame 12, and one end is located at the loading station and the other end is located at the unloading station. When the screen inspection on a material seat 4 is completed, the output end of the two-dimensional mobile platform 2 moves to the loading station. At this time, the loading slide 82 drives the new material seat 4 that has been loaded to move to the position corresponding to the material seat 4 on the two-dimensional mobile platform 2. At this time, the new material seat 4 slides toward the output end of the two-dimensional mobile platform 2, and the material seat 4 on the output end of the two-dimensional mobile platform 2 is pushed onto the output end of the first linear guide 7, so that the material seat 4 on the output end of the two-dimensional platform slides to the output end of the first linear guide 7, so that the new material seat 4 slides to the output end of the two-dimensional mobile platform 2. At this time, the two-dimensional mobile platform 2 is in operation, driving the new material holder 4 to move, so as to detect the new screen. The first linear guide rail 7 operates to move the old material holder 4 to the unloading slide 81 for unloading. After unloading, the unloading slide 81 moves to the position of the second frame 12. At this time, the old material holder 4 slides to the second linear guide rail 83, and is transported to the loading slide 82 through the second linear guide rail 83. Loading is carried out on the loading slide 82. After loading, a new material holder 4 is formed. The new material holder 4 is driven by the loading slide 82 to move to the position of the first frame 11, waiting for the material holder 4 to be replaced.

[0040] Specifically, the top surface of the transparent cover plate 42 and the bottom surface of the transparent base 41 are fixedly connected with a dovetail-shaped protrusion, and the output end of the two-dimensional mobile platform 2, the top surface of the loading slide 82, the top surface of the unloading slide 81, the output end of the first linear guide 7, and the output end of the second linear guide 83 are all provided with dovetail grooves adapted to the dovetail-shaped protrusion. Through the cooperation of the dovetail-shaped protrusion and the dovetail groove, a sliding connection and a detachable connection between the material seat 4 and the output end of the mobile platform, the top surface of the loading slide 82, the top surface of the unloading slide 81, the output end of the first linear guide 7, and the output end of the second linear guide 83 are achieved.

[0041] Specifically, a loading member 62 is fixedly connected to the loading rack 6, and the loading member 62 pushes the new material seat 4 to move, so that the new material seat 4 pushes the old material seat 4 to slide, thereby realizing that the new material seat 4 moves to the output end of the two-dimensional moving platform 2, and the old material seat 4 moves to the output end of the first linear guide rail 7. The loading member 62 adopts an electric telescopic rod. In other embodiments, the loading member 62 can also adopt a telescopic cylinder or other mechanism that can be electrically controlled to extend and retract.

[0042] Furthermore, a second magnet 21 is fixedly connected to the output end of the two-dimensional mobile platform 2, and an iron sheet is fixedly connected to the material seat 4. When the material seat 4 moves to the output end of the two-dimensional mobile platform 2, the second magnet 21 attracts the iron sheet, thereby fixing the material seat 4 and enhancing the stability of the material seat 4 during the movement of the two-dimensional mobile platform 2.

[0043] Furthermore, a first magnet 71 is fixedly connected to the output end of the first linear guide rail 7. When the old material seat 4, that is, the material seat 4 after the screen detection, slides to the output end of the first guide rail, the first magnet 71 absorbs the iron sheet, thereby fixing the material seat 4 and enhancing the stability of the material seat 4 during the movement of the two-dimensional moving platform 2.

[0044] Furthermore, a third magnet 811 is fixedly connected to the unloading slide 81, and the magnetic force of the third magnet 811 is greater than that of the first magnet 71. When the first linear guide rail 7 drives the material seat 4 to move to directly above the unloading slide 81, the upper end of the material seat 4 is slidingly connected to the output end of the first linear guide rail 7, and the lower end of the material seat 4 is slidingly connected to the unloading slide 81. The upper end of the material seat 4 and the first magnet 71 attract each other, and the lower end of the material seat 4 and the third magnet 811 attract each other. At this time, the output end of the first linear guide rail 7 moves away from the unloading slide 81. Due to the adsorption effect of the third magnet 811, the first magnet 71 and the material seat 4 are separated from each other, so that the material seat 4 remains on the unloading slide 81. At this time, the transparent cover 42 is opened and unloading can be carried out.

[0045] Specifically, a circulating member 84 is fixedly connected to the unloading rack 5, and the circulating member 84 is used to push the material seat 4 on the unloading slide 81 to the output end of the second linear guide 83, so as to realize the cyclic movement of the material seat 4. In this embodiment, the circulating member 84 adopts an electric telescopic rod, and the material seat 4 is pushed by the electric telescopic rod to slide from the unloading slide 81 to the output end of the second linear guide 83, and then the output end of the second linear guide 83 drives the material seat 4 to move to the loading station. The output end of the second linear guide 83 is also fixedly connected to the first magnet 71 for fixing the material seat 4.

[0046] Specifically, two circulating parts 84 are also fixed on the loading rack 6. The circulating parts 84 on the loading rack 6 are fixedly connected with a permanent magnet at one end close to the second linear guide 83. When the output end of the second linear guide 83 moves to the loading station, the loading slide 82 slides to be aligned with the output end of the second linear guide 83. At this time, the circulating parts 84 on the loading rack 6 are extended and adsorbed with the material seat 4. Then the circulating parts 84 on the loading rack 6 are contracted to pull the material seat 4 onto the loading slide 82. At this time, the transparent cover 42 is rotated to open, and the loading robot 61 loads the material.

[0047] The implementation principle of the embodiment of the present application is as follows: after the first material seat 4 is inspected, it is moved to the loading station, and the material seat 4 on the loading slide 82 slides toward the two-dimensional moving platform 2, so that the material seat 4 on the two-dimensional moving platform 2 slides onto the first linear guide rail 7. At this time, the material seat 4 on the loading slide 82 slides onto the two-dimensional moving platform 2, and the material seat 4 on the two-dimensional moving platform 2 performs inspection. The material seat 4 on the first linear guide rail 7 moves to the unloading slide 81, and the material is unloaded and loaded on the unloading slide 81, and then transported to the loading slide 82 through the second linear guide rail 83 for loading, waiting for the next inspection. By replacing the two material seats 4, the simultaneous operation of loading and unloading and inspection is realized, thereby increasing the efficiency of the inspection screen.

[0048] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
