Description

Technical Field

[0001] This utility model relates to the field of light transmittance testing technology, and in particular to a light transmittance testing device for high-light-transmittance acrylic sheets. Background Technology

[0002] Acrylic sheets are widely used in many fields due to their excellent optical properties, high transparency, and good weather resistance. Light transmittance is an important indicator for measuring the optical quality of acrylic sheets. It reflects the material's ability to allow light to pass through, and high light transmittance means better visual effects and higher light efficiency.

[0003] Current acrylic sheet transmittance testing procedures typically involve placing the sheet in a fixed groove to ensure its stability and positioning accuracy during testing. However, this traditional method makes it inconvenient for operators to remove the acrylic sheet after testing, increasing work complexity and reducing overall efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-transmittance acrylic sheet transmittance testing device.

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

[0006] A high-transmittance acrylic sheet transmittance testing device includes a worktable. Support columns are fixedly connected to the four corners of the lower end of the worktable. Two first telescopic grooves and two second telescopic grooves are respectively opened on both sides of the upper end of the worktable. A telescopic mechanism connected to the two first telescopic grooves is provided at the lower end of the worktable. A movable plate is slidably arranged above the two second telescopic grooves. A sliding groove is opened on one side of the upper end of the worktable. A driving mechanism for driving the movable plate to move is provided in the sliding groove. A receiving device and a transmitting device are fixedly connected to the upper and lower ends of the worktable, respectively.

[0007] As a further improvement of this utility model, the telescopic mechanism includes a support frame fixedly connected to the lower end of the workbench. Two hydraulic cylinders are installed in the support frame. The telescopic ends of the two hydraulic cylinders pass through a first telescopic groove and are fixedly connected to a lifting block. The two lifting blocks slide in the two first telescopic grooves respectively.

[0008] As a further improvement of this utility model, the driving mechanism includes a threaded rod disposed in a sliding groove. One end of the threaded rod is rotatably connected to the inner wall of the sliding groove, and the other end of the threaded rod passes through the sliding groove and extends outward. A motor is installed on one end of the worktable, and the output shaft end of the motor is fixedly connected to the outwardly extending end of the threaded rod. A sliding block with the threaded rod threadedly connected to one end of the moving plate is fixedly connected below it, and the sliding block slides in the sliding groove.

[0009] As a further improvement of this utility model, two receivers are fixedly connected to the lower part of the upper side of the receiving device, and the positions of the two receivers correspond to the two second telescopic slots respectively.

[0010] As a further improvement of this utility model, two transmitters are fixedly connected above one side of the lower end of the launching device, and the positions of the two transmitters correspond to the two second telescopic slots respectively.

[0011] As a further improvement of this utility model, two placement slots are provided at the upper end of the movable plate, and a through groove matching the size of the second telescopic groove is provided at the bottom of the inner side of each of the two placement slots.

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

[0013] By incorporating a telescopic mechanism and a combination of hydraulic cylinders and lifting blocks, the acrylic sheet can be automatically lifted from the placement slot after testing, greatly simplifying the operation process and reducing the time and difficulty of manual intervention. This not only increases the speed of sample replacement after a single test but also reduces the labor intensity of workers, thereby significantly improving overall work efficiency and the operating speed of the production line.

[0014] By setting up a drive mechanism and a moving plate, and using a motor as the power source, the horizontal displacement of the moving plate is achieved by rotating a threaded rod. This ensures that the acrylic plate can move smoothly and accurately between the second and first telescopic grooves. By reducing the influence of human factors, the accuracy of the test results is further improved.

[0015] This invention not only enables automatic ejection of acrylic sheets after testing, simplifying the operation process, but also provides an automated solution for smooth and precise movement of samples between different positions, significantly improving testing efficiency and accuracy.

Detailed Implementation

[0021] 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.

[0022] Figures 1-4 A high-transmittance acrylic sheet transmittance testing device includes a workbench 1. Two identical first telescopic grooves 3 and two identical second telescopic grooves 18 are respectively opened on both sides of the upper end of the workbench 1. A telescopic mechanism connected to the two first telescopic grooves 3 is provided at the lower end of the workbench 1. The telescopic mechanism includes a support frame 8 fixedly connected to the lower end of the workbench 1. Two hydraulic cylinders 9 are installed inside the support frame 8. The telescopic ends of the two hydraulic cylinders 9 respectively pass through one of the first telescopic grooves 3 and are each fixedly connected to a lifting block 10. The two lifting blocks 10 slide within the two first telescopic grooves 3. The vertical movement of the lifting blocks 10 is achieved through the telescopic action of the hydraulic cylinders 9, thereby enabling the acrylic sheet after testing to be ejected from the placement groove 11, facilitating the operator to remove the sample.

[0023] A movable plate 6 is slidably mounted above the two second telescopic slots 18. Two placement slots 11 are formed at the upper end of the movable plate 6. Each placement slot 11 has a through groove 17 at its inner bottom that matches the size of the second telescopic slot 18. The movable plate 6 can slide horizontally on the worktable 1, ensuring a smooth transition between the testing position and the preparation position for the acrylic sheet. The placement slots 11 and through grooves 17 ensure the acrylic sheet remains stable during testing and does not obstruct the passage of light rays. A sliding groove 4 is formed on one side of the upper end of the worktable 1. A drive mechanism for moving the movable plate 6 is located within the sliding groove 4. The drive mechanism includes a threaded rod 12 disposed within the sliding groove 4. One end of the threaded rod 12 is rotatably connected to the inner wall of the sliding groove 4, and the other end of the threaded rod 12... One end of the sliding plate 6 passes through the sliding groove 4 and extends outward. A motor 7 is installed on one end of the worktable 1. The output shaft of the motor 7 is fixedly connected to the outward-extending end of the threaded rod 12. A sliding block 16 threadedly connected to the threaded rod 12 is fixedly connected to the lower end of one end of the moving plate 6. The sliding block 16 slides in the sliding groove 4. The driving mechanism composed of the sliding groove 4 and the threaded rod 12 is the power source for the horizontal movement of the moving plate 6. The motor 7 drives the threaded rod 12 to rotate, which causes the threaded rod 12 to drive the sliding block 16 to move. The movement of the sliding block 16 will indirectly drive the moving plate 6 to make precise displacement along the direction of the sliding groove 4, ensuring the positioning accuracy during the test. A receiving device 5 and a transmitting device 13 are fixedly connected to the upper and lower ends of the worktable 1, respectively.

[0024] Two receivers 14 are fixedly connected to the lower part of the upper side of the receiving device 5. The positions of the two receivers 14 correspond to the two second telescopic slots 18 respectively. Two transmitters 15 are fixedly connected to the upper part of the lower side of the transmitting device 13. The positions of the two transmitters 15 correspond to the two second telescopic slots 18 respectively. The position settings of the receivers 14 and transmitters 15 ensure that they can be accurately aligned with the acrylic sheet under test, ensuring that the light can pass through the sheet smoothly and be captured by the receivers 14, thereby obtaining reliable light transmittance data.

[0025] In use, the worker first places two acrylic sheets in the two placement slots 11, then starts the motor 7 to drive the threaded rod 12 to rotate. The rotation of the threaded rod 12 will drive the sliding block 16 to move, and the movement of the sliding block 16 will drive the moving plate 6 to move, thereby moving the two acrylic sheets to the positions of the two second telescopic slots 18. Then, the transmitting device 13 is started. The transmitting device 13 emits two light beams through two transmitters 15. The two light beams are received by two receivers 14 after passing through the two acrylic sheets. The two receivers 14 transmit the data to the receiving device 5 for analysis. Finally, the data is displayed on the display device. After the test is completed, the motor 7 is driven again to drive the two acrylic sheets back to the positions of the two first telescopic slots 3. Then, the two hydraulic cylinders 9 are driven to drive the lifting block 10 to push the two acrylic sheets out, making it easy for the worker to remove them.

[0026] 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.
