Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, and in particular to a thickness measuring device for finished acrylic sheet products. Background Technology

[0002] Acrylic sheets, as an important type of organic glass material, are widely used in light box manufacturing, advertising displays, furniture making, and other fields due to their good light transmission, pure colors, rich colors, and beautiful and flat appearance. However, the thickness of acrylic sheets has a significant impact on their light transmittance, strength, and overall performance.

[0003] Traditional manual measurement methods require operators to measure different positions of each acrylic sheet individually, which is time-consuming and labor-intensive, and makes it difficult to quickly measure a large number of sheets, affecting production efficiency and increasing production costs. At the same time, it is difficult to detect the flatness of the sheet, which has a significant impact on the performance of acrylic sheets. Uneven sheets may cause light scattering and affect the visual effect. In order to solve the above problems, this utility model provides a thickness measuring device for finished acrylic sheets. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a thickness measuring device for finished acrylic sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A thickness measuring device for finished acrylic sheets includes a worktable. A first mounting groove is formed at the middle of the upper surface of the worktable. A first bolt is rotatably connected inside the first mounting groove. A movable seat is threaded onto the surface of the first bolt and is movably connected to the first mounting groove. A fixing plate is fixedly connected to the upper surface of the movable seat. A fixing component is provided on the upper surface of the fixing plate. Mounting frames are fixedly connected to the middle of both sides of the worktable. Several connecting seats are fixedly connected to the upper end of the mounting frames. An infrared rangefinder is fixedly connected to the front of each of the connecting seats.

[0007] As a further improvement of this utility model, the fixing component includes a second mounting groove formed at the middle of the upper surface of the fixing plate, a second threaded screw is rotatably connected inside the second mounting groove, and two adjusting seats are threadedly sleeved on the surface of the second threaded screw, and a U-shaped placement plate is fixedly connected to the upper end of each of the two adjusting seats.

[0008] As a further improvement of this utility model, threaded holes are provided at both ends of the upper surface of the U-shaped placement plate, and adjusting bolts that are adapted to the threaded holes are threadedly connected to both ends of the upper surface of the U-shaped placement plate. A clamping plate is rotatably connected to the lower end of the adjusting bolts, and a scale is fixedly connected to the back of the U-shaped placement plate.

[0009] As a further improvement of this utility model, a servo motor is fixedly connected to the front of the workbench, the power end of the servo motor is fixedly connected to the first bolt screw, a handle is rotatably connected to one side of the fixed plate, and the other end of the handle is fixedly connected to the second threaded screw.

[0010] As a further improvement of this utility model, the upper surface of the workbench is provided with sliding grooves on both sides, and the lower surface of the fixing plate is fixedly connected with pulleys that are compatible with the sliding grooves on both sides.

[0011] As a further improvement of this utility model, bases are fixedly connected to both sides of the lower surface of the workbench.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a fixed component, during use, rotating the handle drives the second threaded screw to rotate, which in turn drives two adjusting seats with opposite threads to move towards each other. This design ensures that the U-shaped placement plate adapts to the width of the acrylic sheet, achieving fast and precise clamping. At the same time, by adjusting the bolts to drive the clamping plate downwards, the acrylic sheet can be firmly fixed. This allows the device to adapt to acrylic sheets of different widths and thicknesses without the need to replace or adjust the clamping components, enhancing the versatility and practicality of the equipment. It also avoids errors caused by sheet shaking during the testing process, improving the accuracy of the testing.

[0014] By setting up infrared rangefinders, during use, the first bolt screw is driven by a servo motor to rotate, moving the movable seat and fixed plate on the worktable. At the same time, the smooth movement of the pulleys on the slide groove ensures the stability of the movement, allowing the acrylic sheet to pass smoothly through multiple infrared rangefinders on the mounting frame. The cooperation of the servo motor and the threaded screw realizes the automatic movement and positioning of the sheet, reducing reliance on manual operation, improving the automation level of inspection, and reducing labor intensity. At the same time, the infrared rangefinders can acquire distance data at different positions of the sheet in real time, thereby comprehensively and accurately assessing the flatness of the sheet and providing a reliable basis for subsequent processing or use.

[0015] By setting a scale, the operator can directly read the thickness of the board while fixing it, eliminating the need for additional measuring tools, thus simplifying the operation process and improving work efficiency.

[0016] In summary, this invention not only improves the efficiency and accuracy of acrylic sheet flatness testing, but also enhances the flexibility and versatility of the equipment, and reduces the difficulty and cost of operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A thickness measuring device for finished acrylic sheets includes a worktable 1. A first mounting groove 2 is formed at the middle of the upper surface of the worktable 1. A first bolt rod 3 is rotatably connected inside the first mounting groove 2. A movable seat 4 is threaded onto the surface of the first bolt rod 3. The movable seat 4 is movably connected to the first mounting groove 2. A fixing plate 5 is fixedly connected to the upper surface of the movable seat 4. A fixing component is provided on the upper surface of the fixing plate 5. Mounting frames 6 are fixedly connected to the middle of both sides of the worktable 1. Several connecting seats 7 are fixedly connected to the upper end of the mounting frames 6. An infrared rangefinder 8 is fixedly connected to the front of each of the several connecting seats 7.

[0024] In this invention, the fixing component includes a second mounting groove 9 formed in the middle of the upper surface of the fixing plate 5. A second threaded rod 10 is rotatably connected inside the second mounting groove 9. Two adjusting seats 11 are threadedly sleeved on the surface of the second threaded rod 10. A U-shaped placement plate 12 is fixedly connected to the upper end of each of the two adjusting seats 11. The acrylic sheet to be tested is placed on the fixing plate 5, specifically in the middle area of ​​the two U-shaped placement plates 12. Then, the second threaded rod 10 is driven to rotate inside the second mounting groove 9 by rotating the handle 17. The second threaded rod 10 can push the two adjusting seats 11 with reverse threads to move towards each other, thereby driving the two U-shaped placement plates 12 to gradually approach each other until they are tightly fitted to the width of the acrylic sheet, thus achieving initial fixing.

[0025] Both ends of the upper surface of the U-shaped placement plate 12 are provided with threaded holes. Both ends of the upper surface of the U-shaped placement plate 12 are threadedly connected with adjusting bolts 13 that are compatible with the threaded holes. The lower end of the adjusting bolts 13 is rotatably connected to a clamping plate 14. A scale 15 is fixedly connected to the back of the U-shaped placement plate 12. By rotating the adjusting bolts 13 at the upper ends of the two U-shaped placement plates 12, the clamping plate 14 is driven to move slowly downward until it is in close contact with the surface of the acrylic sheet, thereby ensuring that one side of the sheet is firmly fixed. By repeating the above adjustment steps, the other side of the acrylic sheet can be fixed. At this time, the thickness information of the acrylic sheet can be quickly and accurately read by observing the scale 15 on the back of the U-shaped placement plate 12.

[0026] A servo motor 16 is fixedly connected to the front of the workbench 1. The power end of the servo motor 16 is fixedly connected to the first bolt screw 3. A handle 17 is rotatably connected to one side of the fixed plate 5. The other end of the handle 17 is fixedly connected to the second threaded screw 10. The servo motor 16 provides power for the rotation of the first bolt screw 3, and the handle 17 drives the rotation of the second threaded screw 10.

[0027] The upper surface of the workbench 1 has sliding grooves 18 on both sides, and the lower surface of the fixed plate 5 has pulleys 19 that are compatible with the sliding grooves 18 on both sides. The lower surface of the workbench 1 has bases 20 on both sides. The sliding grooves 18 and pulleys 19 make the movement of the fixed plate 5 more stable and smooth.

[0028] In use, the acrylic sheet is first placed between the two U-shaped placement plates 12 on the fixing plate 5. The handle 17 is rotated to drive the second threaded screw 10 to rotate within the second mounting groove 9. The rotation of the second threaded screw 10 drives two adjusting seats 11 with opposite threads to move towards each other, thereby moving the two U-shaped placement plates 12 towards each other until they are adapted to the width of the acrylic sheet. Then, the adjusting bolt 13 at the upper end of the U-shaped placement plate 12 is rotated to drive the clamping plate 14 to move downwards until it contacts the acrylic sheet, thus fixing one side of it. The above steps are repeated to fix the other side of the acrylic sheet. The clamping plate 14 is then fixed via the back of the U-shaped placement plate 12. The thickness of the acrylic sheet is obtained by using the scale 15. Finally, the servo motor 16 is started to drive the first bolt screw 3 to rotate in the first mounting groove 2, thereby driving the movable seat 4 to move in the first mounting groove 2. The movable seat 4 drives the fixed plate 5 to move on the worktable 1. While the fixed plate 5 is moving, it can drive the pulley 19 to move on the slide groove 18 of the worktable 1 until the acrylic sheet clamped on the fixed plate 5 passes through several infrared rangefinders 8 on the mounting frame 6. The infrared rangefinders 8 can obtain the distance data of different positions of the acrylic sheet, thereby obtaining the accurate value of the thickness of the acrylic sheet at each position, and at the same time, can detect the flatness of the acrylic sheet.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
