The separator is one of the key materials of lithium-ion batteries and an important part of its industrial chain. The main materials of lithium-ion batteries include positive electrode materials, negative electrode materials, electrolytes and separators. Lithium-ion battery separators have good mechanical properties, chemical stability and high-temperature self-closing properties. They can isolate the positive and negative electrodes of the battery, allow lithium ions to pass through, and prevent battery explosions caused by high temperatures, thereby improving the comprehensive performance of lithium-ion batteries.

[0025] The use method and advantages of the utility model: The bidirectional stretching device which is convenient for limiting the position, when in use, has the following working process:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when using, the user first places the device on a horizontal plane, picks up the processing table 1, installs two supporting legs 11 under the processing table 1, then installs four limiting rings 13 on the side ends of the processing table 1, then installs six fixing clamps 12 on the top of the processing table 1, then picks up the rotating rod 16, sleeves a pushing ring 17 on the outer surface of the rotating rod 16, and then installs the rotating rod 16 above the processing table 1 along the two fixing clamps 12. There are three groups of rotating rods 16 parts in total, two of which are farther apart from each other. The side ends of the rotating rods 16 are rotatably installed with a first rotating motor 18, and the side ends of two adjacent rotating rods 16 are sleeved with the same first transmission belt 19, and then the user picks up the installation frame 2 and installs the first transmission belt 19 inside the installation frame 2. Install the threaded rotating rod 22, and then assemble the two mounting frame 2 parts, and then sleeve the same second transmission belt 24 on the two mounting frames 2, and then install the second rotating motor 23 on one of the threaded rotating rods 22, and then sleeve the connecting plate 25 on the outer surface of the two threaded rotating rods 22, and install two extrusion wheels 26 between the two connecting plates 25, and then install the third rotating motor 27 inside one of the connecting plates 25, and then place the assembled mounting frame 2 part on the side end of the processing table 1 where the limit ring 13 is installed, and then pick up four bolts 21, use the bolts 21 to cooperate with the limit ring 13, install the mounting frame 2 on the side end of the processing table 1, and then install the heat conducting plate 14 inside the processing table 1. , a heater 15 is installed under the heat conducting plate 14. When the user needs to use the device, the user first starts the heater 15, and the heater 15 starts to heat the heat conducting plate 14. Then the user places the film to be biaxially stretched on the processing table 1 and under the pushing ring 17, and then starts the first rotating motor 18. The first rotating motor 18 starts to cooperate with the first transmission belt 19, thereby driving the two rotating rods 16 above the heat conducting plate 14 to rotate, thereby cooperating with the pushing ring 17 to push the film to the installation frame 2. At the same time, the film passes through the top of the heat conducting plate 14 for preheating, and then the user passes one side of the film between the two extrusion wheels 26, and then starts the third rotating motor 27. The third rotating motor 27 drives the two The extrusion wheel 26 rotates, and then the diaphragm will be squeezed and extended to the left and right sides, and the extended diaphragm will be placed under the separate pushing ring 17 on the other side. At this time, the diaphragm installation process is completed, and the first rotating motor 18 at the side end of the rotating rod 16 on a single side is started to push the pushing ring 17 to drive the diaphragm, and at the same time, the second rotating motor 23 is started, and the second rotating motor 23 cooperates with the second transmission belt 24 to drive the two threaded rotating rods 22 to rotate, and cooperates with the connecting plate 25 to drive the extrusion wheel 26 and other parts to slide downward. At this time, when the extrusion wheel 26 descends, it cooperates with the pushing rings 17 rotating on both sides to extend the film in the front and rear directions, and then cooperates with the rotation of the extrusion wheel 26 to achieve the device being able to perform bidirectional stretching on the diaphragm when in use.
