[0002] For some small hard parts, it is necessary to inspect the quality of both the front and back sides, such as the wear and flatness of the front and back sides of ceramic sheets. After the front side of the hard part is inspected, it needs to be turned over to inspect the back side. Currently, machines are used to flip it over. However, during the flipping process, the flipping structure may crush the hard part, or the hard part may cut the flipping structure, thus causing unnecessary losses. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flipping mechanism for flipping hard sheets, which addresses the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A flipping mechanism for flipping rigid sheets includes a frame, a first conveyor belt, a second conveyor belt, an adjusting structure, a first roller, a second roller, a third roller, a fourth roller, a fifth roller, and a sixth roller. The first roller is located at the left end of the first conveyor belt, and the second roller is located at the right end of the first conveyor belt. The second conveyor belt includes a vertical section and a horizontal section. The horizontal section is parallel to the first conveyor belt. The third roller is located at the right end of the horizontal section. The fourth roller is located at the left end of the horizontal section and at the corner where the horizontal section meets the vertical section. The fifth roller is located at the top of the vertical section. The sixth roller is pressed against the corner where the vertical section meets the horizontal section. A rigid sheet passage is formed between the middle of the vertical section and the left end of the first conveyor belt. The adjusting structure is used to adjust the distance between the middle of the vertical section and the left end of the first conveyor belt.

[0006] A preferred embodiment is that the adjusting structure includes an adjusting block, an adjusting belt, a seventh roller, an eighth roller, a ninth roller, and a tenth roller; the seventh roller is coaxially arranged with the fifth roller, the eighth roller is coaxially arranged with the first roller, the eighth roller and the first roller are respectively rotatably connected to the adjusting block, the ninth roller is rotatably connected to the adjusting block, the tenth roller is rotatably connected to the frame, the top of the adjusting belt is connected to the seventh roller, the bottom of the adjusting belt is connected to the tenth roller, the eighth roller and the ninth roller are respectively connected to the middle of the adjusting belt and are used to adjust the tension of the adjusting belt, and slide rails are provided on both sides of the first conveyor belt, with the adjusting block slidably connected to the slide rails.

[0007] In a preferred embodiment, the flipping mechanism for flipping the rigid sheet further includes an upper turntable, an upper guide structure, a lower turntable, and a lower guide structure. The upper turntable is disposed on one side of the first conveyor belt, and the upper guide structure is used to guide the rigid sheet on the surface of the upper turntable to the first conveyor belt. The lower turntable is disposed on one side of the second conveyor belt, and the upper guide structure is used to guide the rigid sheet on the surface of the second conveyor belt to the lower turntable.

[0008] A preferred embodiment is that the upper guide structure includes an upper motor and an upper guide disk, the upper motor drives the upper guide disk to rotate, and the hard sheet on the surface of the upper turntable is guided to the first conveyor belt via the upper guide disk; the lower guide structure includes a lower motor and a lower guide disk, the lower motor drives the lower guide disk to rotate, and the hard sheet on the surface of the second conveyor belt is guided to the lower turntable via the lower guide disk.

[0009] A preferred embodiment is that a first camera for inspecting the quality of the front side of the hard sheet is located directly above the upper turntable, and a second camera for inspecting the quality of the back side of the hard sheet is located directly above the lower turntable.

[0010] The flipping mechanism for flipping rigid sheets provided in this embodiment of the utility model has at least the following beneficial effects: the first roller and the second roller are used to drive the first conveyor belt to rotate, and the first conveyor belt rotates from right to left; the third roller, the fourth roller, the fifth roller and the sixth roller are used to drive the second conveyor belt to rotate, and the horizontal section of the second conveyor belt rotates from left to right; the rigid sheet is placed on the surface of the first conveyor belt, and the rigid sheet moves along the first conveyor belt from right to left. When the rigid sheet moves to the rigid sheet passage, the rigid sheet contacts the vertical section of the second conveyor belt, and the rigid sheet presses against the vertical section of the second conveyor belt and the left end of the first conveyor belt. As the first conveyor belt and the second conveyor belt rotate, the rigid sheet rotates 180 degrees from the rigid sheet passage and is transported to the horizontal section of the second conveyor belt. The rigid sheet moves from the left end to the right end of the horizontal section. The rigid sheet can be rotated 180 degrees from the first conveyor belt to the second conveyor belt. Since the adjustment structure is used to adjust the distance between the middle of the vertical section and the left end of the first conveyor belt, it can prevent the middle of the vertical section and the first conveyor belt from crushing the rigid sheet, or prevent the rigid sheet from cutting the middle of the vertical section or the first conveyor belt.

[0019] like Figures 1 to 4As shown, this application embodiment provides a flipping mechanism for flipping rigid sheets, including a frame 10, a first conveyor belt 20, a second conveyor belt 30, an adjusting structure 40, a first roller 51, a second roller 52, a third roller 53, a fourth roller 54, a fifth roller 55, and a sixth roller 56; the first roller 51 is located at the left end of the first conveyor belt 20, the second roller 52 is located at the right end of the first conveyor belt 20, and the second conveyor belt 30 includes a vertical section 31 and a horizontal section 32, the horizontal section 32 being connected to the first conveyor belt 20. The rollers are parallel to each other. The third roller 53 is located at the right end of the horizontal section 32, the fourth roller 54 is located at the left end of the horizontal section 32 and at the corner of the horizontal section 32 and the vertical section 31, the fifth roller 55 is located at the top of the vertical section 31, and the sixth roller 56 is pressed at the corner of the vertical section 31 and the horizontal section 32. A rigid sheet passage is formed between the middle part of the vertical section 31 and the left end of the first conveyor belt 20. The adjustment structure 40 is used to adjust the distance between the middle part of the vertical section 31 and the left end of the first conveyor belt 20.

[0020] like Figures 1 to 4 As shown, the rigid sheet can be a ceramic sheet. The first roller 51 and the second roller 52 are used to drive the first conveyor belt 20 to rotate, and the first conveyor belt 20 rotates from right to left. The third roller 53, the fourth roller 54, the fifth roller 55 and the sixth roller 56 are used to drive the second conveyor belt 30 to rotate, and the horizontal section 32 of the second conveyor belt 30 rotates from left to right. The rigid sheet is placed on the surface of the first conveyor belt 20 and moves along the first conveyor belt 20 from right to left. When the rigid sheet moves to the rigid sheet passage, the rigid sheet contacts the vertical section 31 of the second conveyor belt 30 and presses against the left end of the vertical section 31 of the second conveyor belt 30 and the first conveyor belt 20. As the first conveyor belt 20 and the second conveyor belt 30 rotate, the rigid sheet rotates 180 degrees from the rigid sheet passage and is conveyed to the horizontal section 32 of the second conveyor belt 30. The rigid sheet moves from the left end to the right end of the horizontal section 32. The rigid sheet can be rotated 180 degrees from the first conveyor belt 20 to the second conveyor belt 30. Since the adjusting structure 40 is used to adjust the distance between the middle of the vertical section 31 and the left end of the first conveyor belt 20, it can prevent the middle of the vertical section 31 and the first conveyor belt 20 from crushing the rigid sheet, or it can prevent the rigid sheet from cutting the middle of the vertical section 31 or the first conveyor belt 20.

[0021] like Figures 1 to 4As shown, the adjustment structure 40 includes an adjustment block 41, an adjustment belt 42, a seventh roller 43, an eighth roller 44, a ninth roller 45, and a tenth roller 46. The seventh roller 43 is coaxially arranged with the fifth roller 55, the eighth roller 44 is coaxially arranged with the first roller 51, the eighth roller 44 and the first roller 51 are rotatably connected to the adjustment block 41, the ninth roller 45 is rotatably connected to the adjustment block 41, and the tenth roller 46 is rotatably connected to the frame 10. The top of the adjustment belt 42 is connected to the seventh roller 43, the bottom of the adjustment belt 42 is connected to the tenth roller 46, and the eighth roller 44 and the ninth roller 45 are connected to the middle of the adjustment belt 42 and are used to adjust the tension of the adjustment belt 42. Slide rails 11 are provided on both sides of the first conveyor belt 20, and the adjustment block 41 is slidably connected to the slide rails 11.

[0022] like Figures 1 to 4 As shown, the seventh roller 43, the eighth roller 44, the ninth roller 45, and the tenth roller 46 can drive the adjusting belt 42 to rotate. The adjusting belt 42 can be used to adjust the width of the rigid sheet passage, thus facilitating the passage of rigid sheets of different thicknesses. The adjusting block 41 can slide along the slide rail 11. When the adjusting block 41 slides to a certain position, the adjusting block 41 is fixed to the slide rail 11, and the width of the rigid sheet passage is fixed. When it is necessary to flip rigid sheets of different thicknesses, the relative position of the adjusting block 41 and the slide rail 11 can be adjusted.

[0023] like Figures 1 to 4 As shown, the flipping mechanism for flipping the rigid sheet further includes an upper turntable 61, an upper guide structure 62, a lower turntable 63, and a lower guide structure 64. The upper turntable 61 is disposed on one side of the first conveyor belt 20, and the upper guide structure 62 is used to guide the rigid sheet on the surface of the upper turntable 61 to the first conveyor belt 20. The lower turntable 63 is disposed on one side of the second conveyor belt 30, and the upper guide structure 62 is used to guide the rigid sheet on the surface of the second conveyor belt 30 to the lower turntable 63. When the upper turntable 61 rotates, the rigid sheet on the surface of the upper turntable 61 rotates together with the upper turntable 61. When the rigid sheet on the surface of the upper turntable 61 rotates to contact the upper guide structure 62, the rigid sheet rotates with the upper guide structure 62 to the first conveyor belt 20, and the rigid sheet moves with the first conveyor belt 20. After the rigid sheet is flipped 180 degrees, it moves to the second conveyor belt 30. The rigid sheet moves along the second conveyor belt 30. When the rigid sheet moves close to the lower guide structure 64, the rigid sheet rotates with the lower guide structure 64 to the lower turntable 63.

[0024] like Figures 1 to 4As shown, the upper guide structure 62 includes an upper motor 65 and an upper guide disk 66. The upper motor 65 drives the upper guide disk 66 to rotate, and the hard sheet on the surface of the upper turntable 61 is guided to the first conveyor belt 20 via the upper guide disk 66. The lower guide structure 64 includes a lower motor 67 and a lower guide disk 68. The lower motor 67 drives the lower guide disk 68 to rotate, and the hard sheet on the surface of the second conveyor belt 30 is guided to the lower turntable 63 via the lower guide disk 68.

[0025] like Figures 1 to 4 As shown, when the upper turntable 61 rotates, the hard sheet on the surface of the upper turntable 61 rotates together with the upper turntable 61. When the hard sheet on the surface of the upper turntable 61 rotates to contact the upper guide structure 62, the upper motor 65 drives the upper guide disk 66 to rotate, and the hard sheet rotates with the upper guide disk 66 to the first conveyor belt 20, and moves with the first conveyor belt 20. After the hard sheet flips 180 degrees, it moves to the second conveyor belt 30, and moves along the second conveyor belt 30. When the hard sheet moves close to the lower guide structure 64, the lower motor 67 drives the lower guide disk 68 to rotate, and the hard sheet rotates with the lower guide disk 68 to the lower turntable 63.

[0026] like Figures 1 to 4 As shown, a first camera for inspecting the quality of the front side of the hard sheet is provided directly above the upper turntable 61. The first camera is used to inspect the quality of the front side of the hard sheet, such as flatness and wear. A second camera for inspecting the quality of the back side of the hard sheet is provided directly above the lower turntable 63. The second camera is used to inspect the quality of the back side of the hard sheet, such as flatness and wear.

[0027] The above are specific embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
