Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding film tensile testing technology, specifically a fixing device for testing the tensile deformation of a metal mesh electromagnetic shielding film. Background Technology

[0002] Metal mesh electromagnetic shielding film is an electromagnetic shielding film manufactured by utilizing the characteristics of microstructured metal mesh, which combines high light transmittance and strong electromagnetic shielding function. Electromagnetic shielding films are widely used in power, medical, and equipment display fields. During the production and processing of electromagnetic shielding films, in order to ensure the quality of the film, it is usually necessary to use testing devices to detect the tensile deformation of the film.

[0003] According to the Chinese Patent Publication No. CN217111816U, entitled "An Electromagnetic Shielding Film Tensile Deformation Detection Device," belonging to the field of electromagnetic shielding, the device includes a base. An electric push rod is fixedly connected to one side of the top of the base. A horizontal plate is fixedly connected to the top of the electric push rod. A mounting block is fixedly connected to the bottom of the horizontal plate. A fixing mechanism is fixedly connected to the bottom of the mounting block. There are two fixing mechanisms, and an electromagnetic shielding film is disposed between the two fixing mechanisms. A connecting rod is fixedly connected to the bottom of the other fixing mechanism. This electromagnetic shielding film tensile deformation detection device, by setting the electric push rod and the horizontal plate, allows for easy adjustment of the position of the fixing mechanism according to the length of the electromagnetic shielding film to be tested during the tensile deformation detection process. This makes the detection device applicable to electromagnetic shielding films of different sizes, thereby improving the practicality of the detection device.

[0004] The device's fixing mechanism is suitable for electromagnetic shielding films of different sizes. However, during the stretching process, the electromagnetic shielding film will shake, resulting in instability and affecting the detection effect. Utility Model Content

This device can not only accommodate electromagnetic shielding films of different sizes, but also prevent the electromagnetic shielding film from shaking during the stretching process, thereby increasing the stability of the stretching process and avoiding affecting the detection results.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A fixing device for detecting the tensile deformation of a metal mesh electromagnetic shielding film includes a base, on which a fixed seat and a sliding seat are provided. Both the fixed seat and the sliding seat are provided with a U-shaped frame. A rotating roller is rotatably mounted on the U-shaped frame on the fixed seat, and a fixed roller is fixedly mounted on the U-shaped frame on the sliding seat. Both the rotating roller and the fixed roller have a fixing groove along their axis, with the fixing groove on the fixed roller located on the side away from the rotating roller. A frame is provided above the fixing groove, and a pressure plate is slidably mounted within the frame. A pressure block is provided at the bottom of the pressure plate corresponding to the fixing groove. A locking bolt is threadedly connected to the top of the frame.

[0008] Preferably, the base is provided with a lead screw and a guide rod, and the sliding seat is disposed on the lead screw and the guide rod.

Fix both ends of the electromagnetic shielding film to be tested onto the rotating roller and the fixed roller respectively. Move the sliding seat away from the rotating roller to flatten the electromagnetic shielding film. Rotate the rotating roller to stretch the electromagnetic shielding film. This method can not only accommodate electromagnetic shielding films of different sizes, but also prevent the electromagnetic shielding film from shaking during the stretching process, increasing the stability of the stretching process and avoiding affecting the test results.

[0019] This utility model provides the following technical solution:

[0020] Combination Figures 1 to 3 As shown in the figure, a fixing device for detecting the tensile deformation of a metal mesh electromagnetic shielding film disclosed in this embodiment includes a base 1. A fixed seat 2 and a sliding seat 3 are provided on the base 1. A U-shaped frame 4 is provided on both the fixed seat 2 and the sliding seat 3. A rotating roller 5 is rotatably mounted on the U-shaped frame 4 on the fixed seat 2. A fixed roller 6 is fixedly mounted on the U-shaped frame 4 on the sliding seat 3. A fixing groove 7 is provided along the axis on both the rotating roller 5 and the fixed roller 6. The fixing groove 7 on the fixed roller 6 is located on the side away from the rotating roller 5. A frame 8 is provided above the fixing groove 7. A pressure plate 9 is slidably mounted inside the frame 8. A pressure block 10 is provided at the bottom of the pressure plate 9 corresponding to the fixing groove 7. A locking bolt 11 is threadedly connected to the top of the frame 8.

[0021] Slide the sliding seat 3 towards the fixed seat 2, bringing the rotating roller 5 and the fixed roller 6 closer together. Pull the pressure plate 9 outward to separate the pressure block 10 from the fixed groove 7. Insert one end of the electromagnetic shielding film to be tested between the pressure block 10 and the fixed groove 7 of the rotating roller 5, and insert the other end of the electromagnetic shielding film to be tested between the pressure block 10 and the fixed groove 7 of the fixed roller 6. Tighten the locking bolt 11, and the lower end of the locking bolt 11 presses against the pressure plate 9. Guide strips are provided on both sides inside the frame 8, and guide grooves are provided on both sides of the pressure plate 9 corresponding to the guide strips, allowing the pressure plate 9 to slide smoothly. The pressure block 10 presses against the electromagnetic shielding film. The end of the shielding film is pressed into the fixing groove 7. The two ends of the electromagnetic shielding film to be tested are fixed on the rotating roller 5 and the fixed roller 6 respectively. The rotating roller 5 is rotated to fix one end of the electromagnetic shielding film on the rotating roller 5 to the side away from the fixed roller 6. The sliding seat 3 is moved to the side away from the rotating roller 5 to flatten the electromagnetic shielding film. The rotating roller 5 is rotated to stretch the electromagnetic shielding film. This not only can accommodate electromagnetic shielding films of different sizes, but also can avoid the electromagnetic shielding film shaking during the stretching process, increasing the stability during the stretching process and avoiding affecting the test results.

[0022] Specifically, in combination Figure 2 As shown, a lead screw 12 and a guide rod 13 are provided on the base 1, and the sliding seat 3 is provided on the lead screw 12 and the guide rod 13.

[0023] The sliding seat 3 is threaded onto the lead screw 12. By rotating the lead screw 12, the sliding seat 3 is moved to move the rotating roller 5 and the fixed roller 6 closer or further apart. At the same time, the self-locking feature of the lead screw 12 can fix the position of the sliding seat 3 after it has moved. The sliding seat 3 is slidably set on the smooth rod 13, making the movement of the sliding seat 3 more stable.

[0024] Specifically, in combination Figure 2 As shown, a crank handle 14 is connected to the end of the lead screw 12.

[0025] The crank handle 14 facilitates the rotation of the lead screw 12.

[0026] Specifically, in combination Figure 2 As shown, a rotating wheel 15 is provided on the rotating shaft of the rotating roller 5.

[0027] The rotating roller 5 is driven to rotate by rotating the rotating wheel 15, which facilitates the stretching of the electromagnetic shielding film.
