[0002] In related technologies, PET film testing is mostly conducted manually, such as manually pressing the film and manually recording test data. This not only consumes a lot of time and manpower, but also easily leads to inaccurate test results and untimely data recording due to human factors. Furthermore, because the film material is soft and thin, it is very easy to develop wrinkles or unevenness during placement and testing, making it impossible to obtain an ideal test surface. This results in significant errors in the film width, thickness, and other information obtained during testing, which seriously affects the accuracy of the quality and performance evaluation and analysis of PET film samples and makes it difficult to meet the current demand for high-precision film testing.

[0003] Therefore, due to the fact that PET film is prone to wrinkles or unevenness during testing, it is impossible to obtain an ideal test surface, resulting in large errors in the obtained film width, thickness and other information.

[0066] PET film is made from polyethylene terephthalate (PET) resin through a polycondensation reaction of dimethyl terephthalate and ethylene glycol, and then biaxially stretched into a film. Its molecular chains are regularly arranged, exhibiting good crystallinity and orientation, resulting in excellent physical properties. As a high-performance polymer material, PET film (polyethylene terephthalate film) has wide applications in packaging, electronics, optics, and many other fields. With the increasing demands for quality and performance from various industries, accurate testing and evaluation of PET film parameters have become crucial. In related technologies, PET film testing is mostly conducted manually, such as manually pressing the film and manually recording test data. The inventors found that this testing process not only consumes a lot of time and manpower, but is also prone to inaccurate test results and untimely data recording due to human factors. Furthermore, because the film material is soft and thin, it is very easy to develop wrinkles or unevenness during placement and testing, making it impossible to obtain an ideal test surface. This results in significant errors in the film width, thickness, and other information obtained from the test, which seriously affects the accuracy of the quality and performance evaluation and analysis of PET film samples and makes it difficult to meet the current demand for high-precision film testing.

[0067] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0068] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0069] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0070] like Figure 1 and Figure 4 As shown, at least one disclosed embodiment provides a PET film sample testing device, including: a PET film placement platform 5, which has a film smoothing area on at least one side, with PET film bodies 3 extending from the PET film placement platform 5 to the corresponding film smoothing area; a control module for controlling a smoothing mechanism 1; wherein the smoothing mechanism 1 includes: smoothing components 11 arranged vertically, each of the two smoothing components 11 having a smoothing element 115, the two smoothing elements 115 being arranged vertically with a film smoothing gap between them; and a driver 117 electrically connected to the control module to drive the smoothing element 115 to move back and forth, smoothing the PET film body 3 passing through the film smoothing gap, thereby realizing the smoothing operation of the smoothing roller 115 on the surface of the PET film body 3, effectively eliminating wrinkles or unevenness on the surface of the PET film body 3, providing a more ideal test surface for testing, ensuring the accuracy of the data detected during the testing of the PET film body 3, and ensuring the test results of the PET film body 3.

[0071] A PET film placement platform 5 supports a PET film body 3, with a portion of the PET film body 3 extending from the PET film placement platform 5 and located in the film flattening area. A smoothing mechanism 1 corresponds to the portion of the PET film body 3 extending from the PET film placement platform 5. The smoothing mechanism 1 is electrically connected to a control module, which controls it to smooth the extended portion of the PET film body 3. The smoothing mechanism 1 includes a pair of smoothing components 11. The two smoothing components 11 are arranged vertically, with the upper smoothing component 11 mounted on the pressing mechanism 2 on the PET film placement platform 5, and the lower smoothing component 11 mounted on the PET film. On the film placement platform 5, the upper smoothing component 11 contacts the top surface of the protruding part of the PET film body 3, and the lower smoothing component 11 contacts the bottom surface of the protruding part of the PET film body 3. The control module controls the two smoothing components 11 to move synchronously to smooth the protruding part of the PET film body 3, thereby realizing the smoothing operation of the smoothing roller 115 on the surface of the PET film body 3, effectively eliminating wrinkles or unevenness on the surface of the PET film body 3, providing a more ideal test surface for testing, ensuring the accuracy of the data detected during the testing of the PET film body 3, and ensuring the test results of the PET film body 3.

[0072] In this embodiment, the PET film placement platform 5 is used to support the PET film body 3. The width of the PET film placement platform 5 can be wider than the width of the PET film body 3, which can ensure that the PET film body 3 maintains a stable placement state during the test, avoids the test results being affected by uneven placement surface, and allows the PET film body 3 to extend out of the PET film placement platform 5 from one or both sides of the PET film placement platform 5 in the length direction after being placed on the PET film placement platform 5. The smoothing mechanism 1 can smooth the part of the PET film body 3 that extends out of the PET film placement platform 5. The part of the PET film body 3 located on the PET film placement platform 5 can be the part that has already been tested, ensuring that the PET film body 3 can be completely tested.

[0073] In this embodiment, the PET film placement platform 5 can be set on the base 4, which provides a stable installation platform.

[0074] like Figure 3 As shown, in one optional embodiment, the smoothing assembly 11 includes: a pair of screws 111; both the PET film placement platform 5 and the pressing mechanism 2 are provided with support blocks 112 corresponding to the screws 111, the screws 111 are arranged laterally and pass through the support blocks 112; a slider 113 is threadedly connected to the screws 111, and a smoothing roller 115 is rotatably connected between the sliders 113 on the two screws 111, the smoothing roller 115 contacting the top or bottom surface of the corresponding PET film body 3 protruding portion; a connecting rod 113 is threaded through the slider 113 and connected to the screws 111. 11 parallel guide rods 116 are connected to support block 112; the screw 111 and the corresponding driver 117 are connected through rotating rod 118. The driver 117 is electrically connected to the control module. The control module controls the driver 117 to drive the rotating rod 118 to rotate, so as to drive the screw 111 to rotate. The sliders 113 on the two screws 111 move in the same direction along the screws 111, driving the smoothing roller 115 to move to smooth the PET film body 3 passing through the film smoothing gap, that is, to smooth the part of the PET film body 3 located in the film smoothing area.

[0075] In this embodiment, the guide rod 116 can prevent the slider 113 from deviating or wobbling during the sliding process, ensuring the smoothness and accuracy of the slider 113's movement.

[0076] In this embodiment, the two sliders 113 can be connected by a connecting rod 114. The smoothing roller 115 is sleeved on the connecting rod 114 and is rotatably connected to the connecting rod 114, so that when the sliders 113 move, the smoothing roller 115 can move and rotate with the connecting rod 114.

[0077] In this embodiment, the driver 117 can be a dual-axis motor. When the PET film body 3 has a portion extending from both sides of the PET film placement platform 5, both output ends of the dual-axis motor can be connected to the corresponding screws 111 through the rotating rod 118, so that the portions of the PET film body 3 extending from both sides of the PET film placement platform 5 can be smoothed by the corresponding smoothing rollers 115 at the same time.

[0078] In this embodiment, the two screws 111 in a smoothing component 11 can be connected to the corresponding drivers 117 respectively. The drivers 117 are controlled by the control module to work synchronously, so that the corresponding screws 111 rotate synchronously, driving the smoothing roller 115 to smooth the part of the PET film body 3 that extends out of the PET film placement table 5.

[0079] In this embodiment, the driver 117 can control the rotation direction of the screw 111 according to the rotation direction of the thread on the connected screw 111, so as to ensure that when the two screws 111 in a smoothing assembly 11 rotate, the sliders 113 set on them can move synchronously in the same direction, and the sliders 113 in a pair of smoothing assemblies 11 all move in the same direction, so that the two smoothing rollers 115 move synchronously in the same direction to smooth, ensuring the stable movement of the smoothing rollers 115 and ensuring the smoothing effect.

[0080] In this embodiment, in another implementation, only one of the two screws 111 in a smoothing component 11 can be connected to the driver 117 via a rotating rod 118. The threads on the two screws 111 are arranged in opposite directions. Because the threads on the two screws 111 are arranged in opposite directions, when the driver 117 drives the rotating rod 118 to rotate, the two sliders 113 will slide synchronously in the same direction. This design allows the two sliders 113 to be precisely positioned on the screws 111 to meet the testing requirements of PET film bodies 3 of different sizes.

[0081] In this embodiment, the support block 112 can be used to support the rotating rod 118 connected to the driver 117, ensuring its stability during operation. The rotating rod 118 can pass through the support block 112.

[0082] In this embodiment, the smoothing roller 115 can smooth the PET film body 3 before testing, eliminating any wrinkles or unevenness that may exist on the surface of the PET film body 3, thereby improving the accuracy of the test.

[0083] like Figure 5As shown, in one optional embodiment, a connecting pipe 12 is provided on the corresponding support block 112 of the smoothing component 11 located at the top. An infrared ranging module 13 is provided on the connecting pipe 12, and the infrared ranging module 13 is electrically connected to the control module. The infrared ranging module 13 is closer to the PET film placement platform 5 than the smoothing roller 115, and the infrared ranging module 13 is located above the film smoothing area. The control module detects the dimensional parameters of the PET film body 3, such as thickness, width, and flatness, through the infrared ranging module 13.

[0084] In this embodiment, the connecting tube 12 can be made of a material with a certain degree of flexibility, such as a gooseneck tube, so that the position of the infrared ranging module 13 can be adjusted and the infrared ranging module 13 can be kept stable after adjustment. Furthermore, the infrared ranging module 13 is closer to the PET film placement platform 5 than the smoothing roller 115, so that the PET film body 3 detected by the infrared ranging module 13 is the part that has been smoothed, thus ensuring the detection result.

[0085] In this embodiment, when the slider 113 slides on the screw 111, the position of the infrared ranging module 13 changes accordingly, allowing testing of different positions of the PET film body 3. The infrared ranging module 13 can directly use an infrared rangefinder, specifically a MicroD rangefinder, which can clearly scan and test the width and thickness of the PET film body 3, improving testing accuracy. Alternatively, the infrared ranging module 13 can use an infrared sensor, such as an NS-LVDC capacitive sensor. This sensor has a constant and adjustable measuring force, can adapt to hard or soft material surfaces, and can test film thickness, film height, and surface morphology of micron and nanostructures. It is suitable for film testing of various materials, meeting high-precision testing requirements.

[0086] In one optional embodiment, a sheet sensor 14 is provided on the smoothing roller 115, and the sheet sensor 14 is electrically connected to the control module; the control module detects the pressure distribution of the PET film body 3 through the sheet sensor 14.

[0087] like Figure 2As shown, in one optional embodiment, the pressing mechanism 2 is electrically connected to the control module, and the control module controls the pressing mechanism 2 to press the PET film body 3 portion on the PET film placement platform 5; wherein the pressing mechanism 2 includes: a second motor 21, a lead screw 22, a slide 23, and a pressure plate 24; the lead screw 22 is vertically disposed on one side of the PET film placement platform 5, the lead screw 22 is connected to the second motor 21, and the second motor 21 is electrically connected to the control module; the slide 23 is threadedly connected to the lead screw 22; the pressure plate 24 is disposed on the slide 23, and the pressure plate 24 is located above the PET film placement platform 5; the control module controls the second motor 21 to drive the lead screw 22 to rotate, so that the slide 23 moves up and down along the lead screw 22, thereby driving the pressure plate 24 to move up and down.

[0088] In this embodiment, the pressure plate 24 is raised and lowered by rotating the lead screw 22, so that the pressure plate 24 can accurately press the PET film body 3 on the PET film placement platform 5, avoiding wrinkles caused by the movement of the PET film body 3 during the smoothing process.

[0089] In this embodiment, the pressure plate 24 can be adapted to the size of the PET film placement platform 5 to completely press the PET film body 3 part on the PET film placement platform 5.

[0090] In this embodiment, the threaded connection between the slide 23 and the lead screw 22 can be, but is not limited to, the following: the slide 23 and the lead screw 22 are threaded together, and the connection between the slide 23 and the lead screw 22 is provided with an external thread that engages with the thread of the lead screw 22. When the second motor 21 is started, the lead screw 22 begins to rotate. Due to the threaded engagement between the slide 23 and the lead screw 22, the slide 23 will move up and down along the axial direction of the lead screw 22, thereby realizing the pressing or releasing operation of the pressure plate 24 on the PET film body 3.

[0091] In this embodiment, the driver 117 and the support block 112 in the upper-mounted smoothing component 11 can be disposed on the side wall of the pressure plate 24.

[0092] In one optional embodiment, guide posts 25 are vertically arranged on both sides of the lead screw 22. The bottom of the guide posts 25 is connected to the side wall of the PET film placement platform 5 through a fixing block 27; the top of the guide posts 25 is connected to the connecting plate 26; the slide 23 is slidably connected to the guide posts 25; the top of the lead screw 22 is rotatably connected to the connecting plate 26; and the second motor 21 is connected to the side wall of the PET film placement platform 5 through the fixing block 27.

[0093] In this embodiment, the guide post 25 guides the lifting and lowering of the carriage 23, ensuring that the carriage 23 can move up and down stably along its direction.

[0094] In one optional embodiment, a display 28 is provided on the top surface of the pressure plate 24, and the display 28 is electrically connected to the control module; the control module controls the display 28 to display the pressure distribution of the PET film body 3 and the dimensional parameters of the PET film body 3, so that the operator can intuitively obtain test information.

[0095] In this embodiment, the models of the driver 117 and the second motor 21 can be selected according to the actual size of the PET film body 3 being tested.

[0096] In this embodiment, the smoothing component 11 located at the top can move up and down with the pressure plate 24, which facilitates the placement and removal of the PET film body 3. When the pressure plate 24 presses the PET film body 3, the part of the PET film body 3 that extends out of the PET film placement table 5 is located between the two smoothing rollers 115 and contacts the two smoothing rollers 115.

[0097] In this embodiment, the PET film body 3 is first placed flat on the PET film placement platform 5, so that the two ends of the PET film body 3 naturally hang down on the smoothing roller 115 below. Then, the second motor 21 is started to drive the lead screw 22 to start rotating. The slide 23 is driven by the lead screw 22 and slowly slides down along the guide post 25. The pressure plate 24 gradually approaches the PET film body 3 until it is firmly pressed.

[0098] After the PET film body 3 is pressed and fixed, the smoothing roller 115 begins to move. The driver 117 drives the rotating rod 118 to rotate, which in turn drives the screw 111 to rotate, causing the two sliders 113 to slide synchronously in the same direction. The connecting rod 114 connecting the two sliders 113 moves accordingly, and the smoothing roller 115 mounted on the connecting rod 114 also slides along the surface of the PET film body 3. Since the smoothing roller 115 and the connecting rod 114 are rotatably connected, during the movement, the smoothing roller 115 rolls along the surface of the PET film body 3. While smoothing the PET film body 3, the surface sensor 14 on the surface of the smoothing roller 115 contacts the PET film body 3, accurately detecting information such as the pressure distribution on the surface of the PET film body 3. Simultaneously, the infrared ranging module 13, mounted above the slider 113 via the connecting tube 12, also moves as the slider 113 moves horizontally, accurately testing various dimensional parameters of the PET film body 3.

[0099] All data collected by the chip sensor 14 and the infrared ranging module 13 are transmitted in real time to the display 28 via electrical connection for intuitive display. Operators can conduct a comprehensive evaluation and in-depth analysis of the quality and performance of the PET film body 3 based on the data on the display 28.

[0100] After the test is completed, the second motor 21 is started to reverse, and the slide 23 drives the pressure plate 24 to rise upward, releasing the pressure on the PET film body 3.
