Description

Technical Field

[0001] The utility model relates to the technical field of PI film strength detection, and more specifically, to a PI film biaxial stretching machine device. Background Art

[0002] The PI film biaxial stretching machine is the core equipment for producing polyimide (PI) film. It stretches the film biaxially through precision technology, significantly improving its physical and chemical properties. The device ensures the high strength, high toughness and excellent temperature resistance of the PI film, meeting the needs of aviation, electronics, medical and other fields for high-performance materials. The existing technology uses manual clamps to clamp and fix the PI film. The clamping force is often affected by the operator's experience and feel, resulting in uneven force. Excessive force may damage the film, and too little force may cause the film to shift or fall off during stretching. In addition, the manual clamp needs to clamp each piece, and the operating efficiency is significantly low. In situations where a large number of tensile tests are required, the limitations of the manual clamp become a key factor restricting the progress of the test, affecting the efficiency and accuracy of the test.

[0026] Before the PI film stretching test, the staff needs to clamp and fix the PI film, hold the door handle 4, and use the door handle 4 to drive the movable door 3 to slowly open the inside of the test box 2, hold the connecting rod 25, and use the connecting rod 25 to pull the limit block 24 inside the box 27, and use the limit block 24 to squeeze the spring 26 to slowly make the limit block 24 slowly enter the fixed plate 19 and the box 27, and release the restriction on the movable plate 17 through the limit block 24. The movable plate 17 is squeezed by the spring 1 20, so that the movable plate 17 drives the limit cylinder 21 and the positioning pin 22 to slowly leave the fixed groove 23. Put the PI film between the two clamping blocks 15, then hold the movable rod 16, and use the movable rod 16 to squeeze the movable plate 17 inside the clamping block 15, and then use the movable plate 17 to squeeze the spring 1 20, and through the cooperation between the movable plate 17 and the spring 1 20, the limiting cylinder 21 and the positioning needle 22 slowly enter the inside of the fixing groove 23 to clamp and fix the PI film, release the connecting rod 25, and at this time, use the spring 2 26 to squeeze the limiting block 24 inside the box body 27, so that the limiting block 24 quickly enters the inside of the movable plate 17 to limit the movable plate 17, thereby completing the clamping of the PI film.

[0027] Before the PI film stretching test, the PI film needs to be clamped and fixed, by holding the connecting rod 25, the limit block 24 is pulled inside the box 27 through the connecting rod 25, and the spring 26 is squeezed by the limit block 24, so that the limit block 24 slowly enters the fixed plate 19 and the inside of the box 27, and the restriction on the movable plate 17 is released by the limit block 24, and the movable plate 17 is squeezed by the spring 1 20, so that the movable plate 17 drives the limit cylinder 21 and the positioning pin 22 to slowly disengage from the fixed groove 23. Now put the PI film between the two clamping blocks 15, and then hold the movable rod 16, and squeeze the movable plate 17 inside the clamping block 15 through the movable rod 16, and then squeeze the spring 1 20 through the movable plate 17, and through the cooperation between the movable plate 17 and the spring 1 20, the limit cylinder 21 and The positioning pin 22 slowly enters the interior of the fixing groove 23 to clamp and fix the PI film, and the connecting rod 25 is released. At this time, the limit block 24 is squeezed by the spring 26, so that the limit block 24 quickly enters the interior of the movable plate 17, and the movable plate 17 is limited by the limit block 24. Compared with the traditional device, the device facilitates the clamping and fixing of the PI film through the cooperation between the limit cylinder 21 and the positioning pin 22, which significantly improves the clamping stability, reduces sliding deviation, and ensures the accuracy and consistency of the stretching process. This precise clamping and fixing ensures that the film is stretched according to the predetermined stretching ratio, which is crucial for the production of PI films with specific physical properties, improves product quality, achieves uniform stretching, avoids local stress problems, and improves production efficiency. It reduces production costs and provides reliable guarantees for PI film manufacturing.

[0028] Among them, the internal thread of the sleeve block 14 is sleeved with a bidirectional screw rod 13, and both ends of the bidirectional screw rod 13 completely penetrate the interior of the stretching machine workbench 1, a gear 1 7 is fixedly installed at one end of the bidirectional screw rod 13, a motor 9 is fixedly installed on the right side of the stretching machine workbench 1, a gear 2 8 is fixedly installed on the output end of the motor 9, and the gear 2 8 and the motor 9 are meshed with each other, and a detection box 2 is fixedly installed on the top of the stretching machine workbench 1, a movable door 3 is movably installed on the front of the detection box 2, and a door handle 4 is fixedly installed on the front of the movable door 3.

[0029] After the staff completes the clamping of the PI film, they need to perform a stretching test on the PI film. By turning on the motor 9, the motor 9 drives the gear 2 8 to rotate. The teeth of the gear 2 8 and the gear 1 7 are meshed, and the gear 2 8 drives the gear 1 7 to rotate. The gear 1 7 drives the bidirectional screw 13 to rotate inside the sleeve block 14, so that the sleeve block 14 moves in the opposite direction inside the slide groove 18. The sleeve block 14 drives the clamping block 15 to move in the opposite direction. The PI film is stretched by the two clamping blocks 15. The PI film is tested by opening the detection box 2 to complete the stretching test of the PI film.

[0030] After the PI film is clamped, it is necessary to perform a stretching test on the PI film. The motor 9 is turned on to drive the gear 2 8 to rotate, and the gear 2 8 drives the gear 1 7 to rotate. The gear 1 7 drives the bidirectional screw 13 to rotate inside the sleeve block 14, so that the sleeve block 14 moves in the opposite direction inside the slide groove 18, and the sleeve block 14 drives the clamping block 15 to move in the opposite direction. The two clamping blocks 15 drive the PI film to be stretched, and the PI film is tested by opening the detection box 2. Compared with the traditional device, the clamping block 15 can flexibly move in the opposite direction through the cooperation between the sleeve block 14 and the bidirectional screw 13, which significantly improves the stretching efficiency. This design allows the operator to quickly and accurately adjust the stretching direction and degree to achieve precise stretching control. At the same time, the multi-step and multi-directional stretching of the reverse motion helps to evenly distribute the stretching force, optimize the stretching effect, and make the stretching of the PI film more uniform and stable. The rapid response capability of the clamping block 15 also reduces the risk of film damage, ensuring the safety and reliability of the stretching process.

[0031] A column 5 is fixedly installed at the bottom of the stretching machine workbench 1 , and a base 6 is fixedly installed at the bottom of the column 5 .

[0032] Through the cooperation between the column 5 and the base 6, it is convenient to support the stretching machine workbench 1 and the test box 2, which ensures that the stretching machine workbench 1 and the test box 2 remain stable during the bidirectional stretching process to avoid data errors or equipment damage caused by vibration and shaking.

[0033] A fixing block 11 is fixedly installed on the back of the stretching machine workbench 1 , and a tool box 12 is movably installed inside the fixing block 11 .

[0034] By holding the tool box 12, the tool box 12 is slowly placed into the interior of the fixed block 11, and the tool box 12 is fixed by the fixed block 11. By adding the tool box 12, it is convenient for the staff to take the maintenance tools inside the tool box 12 to repair the detection box 2, thereby improving the use efficiency of the detection box 2.

[0035] A support base 10 is fixedly installed on the right side of the stretching machine workbench 1, and the interior of the support base 10 is in a U-shape.

[0036] Since the interior of the support seat 10 is in a U-shape on the right side of the stretching machine workbench 1, it is convenient to support the motor 9, reduce the shaking of the motor 9 during operation, ensure the stability of the motor 9 during use, and improve the use efficiency of the motor 9.

[0037] The limiting cylinders 21 and the positioning pins 22 are arranged in pairs, and there are four groups at the bottom of the movable plate 17 .

[0038] Since the limiting cylinders 21 and the positioning pins 22 are grouped in pairs, there are a total of four groups at the bottom of the movable plate 17. Through the cooperation between the limiting cylinders 21 and the positioning pins 22, it is convenient to fix the PI film inside the fixing groove 23. By setting up four groups, the fixation of the PI film is more stable, ensuring the detection data during the PI film detection process.

[0039] The working principle and use process of this utility model:

[0040] After the staff completes the clamping of the PI film, they need to perform a stretching test on the PI film. By turning on the motor 9, the motor 9 drives the gear 2 8 to rotate. The teeth of the gear 2 8 and the gear 1 7 are meshed, and the gear 2 8 drives the gear 1 7 to rotate. The gear 1 7 drives the bidirectional screw 13 to rotate inside the sleeve block 14, so that the sleeve block 14 moves in the opposite direction inside the slide groove 18. The sleeve block 14 drives the clamping block 15 to move in the opposite direction. The PI film is stretched by the two clamping blocks 15. The PI film is tested by opening the detection box 2 to complete the stretching test of the PI film.

[0041] Before the PI film stretching test, the staff needs to clamp and fix the PI film, hold the door handle 4, and use the door handle 4 to drive the movable door 3 to slowly open the inside of the test box 2, hold the connecting rod 25, and use the connecting rod 25 to pull the limit block 24 inside the box 27, and use the limit block 24 to squeeze the spring 26 to slowly make the limit block 24 slowly enter the fixed plate 19 and the box 27, and release the restriction on the movable plate 17 through the limit block 24. The movable plate 17 is squeezed by the spring 1 20, so that the movable plate 17 drives the limit cylinder 21 and the positioning pin 22 to slowly leave the fixed groove 23. Put the PI film between the two clamping blocks 15, then hold the movable rod 16, and use the movable rod 16 to squeeze the movable plate 17 inside the clamping block 15, and then use the movable plate 17 to squeeze the spring 1 20, and through the cooperation between the movable plate 17 and the spring 1 20, the limiting cylinder 21 and the positioning needle 22 slowly enter the inside of the fixing groove 23 to clamp and fix the PI film, release the connecting rod 25, and at this time, use the spring 2 26 to squeeze the limiting block 24 inside the box body 27, so that the limiting block 24 quickly enters the inside of the movable plate 17 to limit the movable plate 17, thereby completing the clamping of the PI film.
