DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0041] Embodiment one: please refer to Figures 1-10The existing strength detection device fixes the two ends of the film through a positioning structure before performing a tensile test on the film. After testing a group of films, the device needs to be disassembled and then clamped with another film for subsequent testing. For film processing, a single experimental station cannot efficiently and orderly test different types of films or large quantities of the same type of film, thereby reducing the overall experimental detection efficiency. To solve this technical problem, the present embodiment discloses the following technical content: an experimental machine for insulating film processing, which comprises a positioning base 1 and a support rod 2 installed in the middle of the positioning base 1, and a movable disc 3 is rotatably connected to the support rod 2. The bottom of the movable disc 3 is fixed with a power gear ring 4, and the side of the power gear ring 4 is meshed with a transmission gear 5 fixed on the output end of a servo motor 6. The upper end of the movable disc 3 is fixed with a bearing column 7, and a plurality of butt joints 8 are arranged on the circumference of the bearing column 7. Each butt joint 8 can be inserted into a stretching unit 9. The bearing column 7 drives the stretching unit 9 to rotate and switch when the movable disc 3 rotates. A fixing part 10 is installed on the bearing column 7, which is used to limit one end of the stretching unit 9. A guide frame 11 is installed on the positioning base 1, and a cylinder 12 is fixedly connected to the guide frame 11. The cylinder 12 is used to push the non-fixed end of the stretching unit 9, so as to realize the stretching experiment and detection of the insulating film after being fixed on the stretching unit 9. The stretching unit 9 comprises a first side plate 901 and a clamping groove 902 arranged on the upper end of the first side plate 901. A first magnetic block 903 is inlaid in the clamping groove 902. A contact rod 904 is installed in the middle of the first side plate 901. A limiting rod 905 is fixed on the side of the first side plate 901 away from the contact rod 904. The limiting rod 905 is inserted into the inside of a horizontal moving sleeve 906. The limiting rod 905 and the horizontal moving sleeve 906 are connected by a spring. The horizontal moving sleeve 906 is fixed on a second side plate 907. The horizontal moving sleeve 906 and the limiting rod 905 constitute an elastic extension structure through the spring. The second side plate 907 on the side of the horizontal moving sleeve 906 is parallel to the first side plate 901. The fixing part 10 comprises a transmission rod 101 fixed on the upper end of the support rod 2. An insertion rod 102 is arranged above the transmission rod 101. A second magnetic block 103 is inlaid on the end of the insertion rod 102 close to the first side plate 901. The insertion rod 102 is connected with the bearing column 7 through an auxiliary spring 104. An extrusion block 105 is fixed on the end of the insertion rod 102 close to the contact rod 904. The transmission rod 101 is eccentrically arranged on the upper end of the support rod 2. The lower end surfaces of the transmission rod 101 and the insertion rod 102 are both arranged in an arc shape. The insertion rod 102 can only move along the vertical direction of the bearing column 7. The side of the extrusion block 105 close to the spherical end of the contact rod 904 is arranged as an inclined surface. The second magnetic block 103 on the upper end of the insertion rod 102 has opposite magnetism to that of the first magnetic block 903.And the upper end outer wall of the plug rod 102 and the inner wall of the clamping groove 902 on the first side plate 901 are mutually attached, the side edge of the second side plate 907 is provided with a vertical plate 15, and the vertical plate 15 and the first side plate 901 are both provided with two oppositely arranged clamping blocks 13, the two clamping blocks 13 are provided with a connecting screw rod 14 penetratingly installed thereon, the end block of the vertical plate 15 is slidingly installed on the horizontal moving sleeve 906, and the sliding block of the vertical plate 15 is provided with a pressing bolt 16, which is used for position fixing of the moved vertical plate 15, the two clamping blocks 13 are distributed at the two ends of the connecting screw rod 14, and the thread directions of the two end surfaces of the connecting screw rod 14 are opposite, and the clamping blocks 13 on the first side plate 901 and the vertical plate 15 can be moved thereon.

[0042] When the tension of the multiple insulation films needs to be realized, the two ends of the insulation film are respectively placed between the two clamping blocks 13 on the side edge of the first side plate 901 and the two clamping blocks 13 on the side edge of the vertical plate 15, and then the connecting screw 14 is rotated. After the connecting screw 14 is rotated, the clamping blocks 13 can move relatively, and the two ends of the insulation film can be fixed through the movement of the clamping blocks 13. After that, the vertical plate 15 is moved on the horizontal moving sleeve 906, and the insulation film can be stretched and flattened through the movement of the vertical plate 15. After the vertical plate 15 is moved to the position, the pressing bolt 16 is rotated to press the vertical plate 15 on the horizontal moving sleeve 906, so as to avoid that the insulation film is in a wrinkled state during subsequent detection, which causes uneven stress and affects the final detection result. After the insulation film is fixed, the first side plate 901 on the stretching unit 9 is inserted into the butt joint groove 8 on the side edge of the bearing column 7, and at the same time, the abutting rod 904 on the first side plate 901 can also be inserted into the bearing column 7 after the insertion. When the first side plate 901 is inserted into the position, the first magnetic block 903 in the clamping groove 902 generates a magnetic attraction force on the second magnetic block 103 on the insertion rod 102, at this time the insertion rod 102 is inserted into the clamping groove 902 on the first side plate 901, so as to fix the first side plate 901.

After the transmission gear 5 is rotated, the power tooth ring 4 connected in mesh can drive the rotating disc 3 to rotate, and the rotating disc 3 can drive the fixed stretching unit 9 to rotate in sequence after the rotating disc 3 rotates. Through the opening of the cylinder 12, the extension end can be elongated, and the second side plate 907 can be pushed through the elongated extension end. Through the pushing of the second side plate 907, the vertical plate 15 can be moved synchronously through the horizontal moving sleeve 906. The insulation film can be tensioned by the movement of the vertical plate 15, and the rotating disc 3 is rotated, so that the insulation film can be detected in sequence, and the detection efficiency is improved. When the insulation film on the stretching unit 9 is detected, the rotating disc 3 and the bearing column 7 continue to rotate, and when the insertion rod 102 on the bearing column 7 rotates and gradually contacts the transmission rod 101, the transmission rod 101 can be used to extrude and push the insertion rod 102 upwards. After the insertion rod 102 moves upwards, the clamping groove 902 on the first side plate 901 is first separated, and then the insertion rod 102 continues to rotate with the bearing column 7, and the transmission rod 101 continues to extrude the insertion rod 102. At this time, the insertion rod 102 moves upwards and can push the abutting rod 904 on the first side plate 901 through the inclined surface of the extrusion block 105, so that the abutting rod 904 moves towards the outside of the bearing column 7, and then the first side plate 901 is automatically ejected from the butt joint groove 8 on the bearing column 7, so as to facilitate the subsequent workers to assemble the insulation film again by using the stretching unit 9.

[0043] Embodiment two: the technical content disclosed in this embodiment is a further improvement based on the above embodiment one. In order to facilitate the recording of the tension of the insulating film on each stretching unit 9, the following technical content is disclosed in this embodiment, as shown in Figure 1 、 Figure 6 、 Figure 7 and Figure 10 , the inside of the horizontal moving sleeve 906 is fixed with a laser ranging sensor 908, which is used to detect the distance between the end of the limiting rod 905

[0044] When the cylinder 12 is opened, the telescopic end can be elongated, and the elongated cylinder 12 can push the second side plate 907, and the second side plate 907 can move the horizontal moving sleeve 906 on the limiting rod 905 synchronously, and the horizontal moving sleeve 906 can move the vertical plate 15, thereby stretching the fixed insulating film. The laser ranging sensor 908 inside the horizontal moving sleeve 906 can detect the distance between the end of the limiting rod 905, and through the detection of the distance, the ultimate tension of the insulating film can be calculated.
