If the specific posture changes, the directional indications will also change accordingly.

[0038] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] Refer to Figures 1 to 8As shown, the present invention proposes a film stretching device 100, which aims to solve the problems of the film stretching device 100 used in the polymer film stretching experiment in the related art, such as high equipment requirements and site requirements, difficult structure change, inability to be used in conjunction with other testing devices, and poor flexibility, and improve the adaptability and versatility of the film stretching device 100.

[0040] To achieve the above objectives, the film stretching device 100 proposed in the present invention includes a supporting module 10 , a stretching module 30 , a heating module 50 and a control module 70 . The support module 10 includes a support component 11 and a traction component 13, and the traction component 13 is arranged on the support component 11; the stretching module 30 includes a stretching component 31 and a stretching shell 33, and the stretching shell 33 is detachably arranged on the upper side of the support component 11, and the stretching component 31 is arranged in the stretching shell 33, and the stretching component 31 is fixedly connected to the traction component 13; the heating module 50 includes a heating component 51 and a heating shell 55, and the heating shell 55 is detachably arranged on the upper side of the support component 11 away from the stretching shell 33. The heating component 51 is arranged in the heating shell 55; the control module 70 is arranged on the support component 11, and the control module 70 is used to be electrically connected to the traction component 13, and control the traction component 13 to drive the stretching component 31 to move in the stretching shell 33 and the heating shell 55, and the control module 70 is used to be electrically connected to the heating component 51, and control the heating component 51 to heat the space in the inner cavity of the heating shell 55.

[0041] Specifically, Figures 1 to 4 As shown, before using the film stretching device 100 to perform the film stretching in-situ characterization experiment, the stretching module 30 and the heating module 50 are movably installed side by side on the upper side of the support module 10, the film to be tested is clamped in the stretching assembly 31, and the control module 70 is connected to the power supply required to realize the control action, and the film stretching in-situ characterization experiment can be performed. It can be understood that the stretching shell 33 of the stretching module 30 and the heating shell 55 of the heating module 50, which are arranged side by side on the upper side of the support module 10, have a connected moving space at the connection. In this way, during the experiment, the control module 70 can control the electrically connected traction assembly 13 to drive the stretching assembly 31 to move between the inner cavity of the stretching shell 33 and the inner cavity of the heating shell 55. When the stretching component 31 is located in the inner cavity of the stretching shell 33, an in-situ stretching characterization experiment of the film to be tested can be carried out at room temperature. Correspondingly, when the stretching component 31 moves to the inner cavity of the heating shell 55, the heating component 51 can be controlled by the control module 70 to heat the test space in the inner cavity of the heating shell 55 to a preset temperature and maintain it, so as to meet the demand for an in-situ stretching characterization experiment of the film under a preset temperature environment.

[0042] like Figures 1 to 7As shown, in an embodiment of the present invention, the stretching assembly 31 includes a stretching frame 311, four stretching structures 313, and a driving structure 315. The stretching frame 311 is provided on the support assembly 11, and the traction assembly 13 is fixedly connected to the stretching frame 311; the stretching structures 313 are provided on the stretching frame 311, and the two horizontally arranged stretching structures 313 cooperate with the two vertically arranged stretching structures 313 to form a cross shape; the driving structure 315 includes a driving motor 315a and a transmission member 315b. The driving motor 315a is provided on the stretching frame 311, the control module 70 is electrically connected to the driving motor 315a, the driving motor 315a is drivingly connected to the transmission member 315b, and the transmission member 315b is drivingly connected to the four stretching structures 313. With such a setting, the four stretching structures 313 arranged in a cross shape enclose a test space in the center. The thin film to be tested is clamped and fixed on the side of the stretching structure 313 close to the test space in four directions. The control module 70 is electrically connected to the driving motor 315a and controls the driving motor 315a to drive the transmission member 315b. The transmission member 315b transmits the power of the driving motor 315a and drives the movement of the stretching structure 313, so as to control the stretching movement of the thin film in the test space in four directions on the plane.

[0043] Further, as Figures 6 to 7 shown, the stretching structure 313 includes a rhombic traction mechanism 313a, a linear motion slider 313b correspondingly provided at one end of the rhombic traction mechanism 313a, at least one linear guide rod 313c passing through the linear motion slider 313b, and a clamp 313d correspondingly provided on the side of the linear motion slider 313b away from the rhombic traction mechanism 313a. The transmission member 315b includes a main power guide rail 315c and a power traction slider 315d. The power traction slider 315d is slidably connected to the main power guide rail 315c, and one end of the power traction slider 315d is fixedly connected to one side of the rhombic traction mechanism 313a. During the working process of the stretching assembly 31, the thin film to be tested is clamped and fixed in the test space by the clamp 313d. During the stretching process, the control module 70 controls the driving motor 315a to drive the main power guide rail 315c to move towards or away from each other. Further, the movement of the main power guide rail 315c drives the power traction slider 315d provided thereon to move, and the movement of the power traction slider 315d drives the outermost fixed connection of the rhombic traction mechanism 313a connected thereto to perform corresponding movement towards or away from each other. It can be understood that because the midpoint of the long arm of the rhombic traction mechanism 313a such as Figure 6 and Figure 7As shown, it is fixed as the midpoint of the cross movement. The movement at the two fixed points on both sides of the diamond traction mechanism 313a will drive the entire diamond traction mechanism 313a to perform stretching or compression movement. The movement of the diamond traction mechanism 313a will drive the linear motion slider 313b to perform linear motion along the linear guide rod 313c, thereby driving the film clamped by the fixture 313d to move in the linear direction, that is, to achieve the stretching process. With such a setting, the film can achieve high control accuracy and flexible control methods during the stretching process, realizing stretching in different directions and different steps, such as unidirectional unrestricted stretching, unidirectional restricted stretching, bidirectional synchronous stretching, bidirectional asynchronous stretching, and the movement of the above-mentioned stretching methods under various combined conditions of different stretching rates, temperatures, deformation amounts, implementation sequences, action times, and interval times. Specific limitations are not made here.

[0044] Furthermore, the stretching assembly 31 further includes a heat insulation plate 317. The heat insulation plate 317 is arranged on the side of the stretching frame 311 facing away from the heating housing 55. The outer shape and size of the heat insulation plate 317 are correspondingly set with the shape and size of the opening where the heating housing 55 communicates with the stretching housing 33. With such a setting, during the experiment, when the stretching assembly 31 moves into the heating housing 55, the heat insulation plate 317 is buckled to form a sealed heating space with the heating housing 55, ensuring a good heating effect.

[0045] As Figures 1 to 7 As shown, in an embodiment of the present invention, the traction assembly 13 includes a traction guide rail 131, a traction slider 133, and a traction belt 135. The traction guide rail 131 is arranged on the support assembly 11; the traction slider 133 is fixedly connected to the stretching assembly 31, and the traction slider 133 is slidably arranged on the traction guide rail 131; one end of the traction belt 135 is fixedly connected to the stretching frame 311, and the end of the traction belt 135 facing away from the stretching frame 311 is fixedly connected to the traction slider 133. The traction assembly 13 further includes a traction motor. The traction motor can drive the traction belt 135 to move in the horizontal direction. When the stretching mechanism needs to move between the normal temperature housing and the heating housing 55, the control module 70 controls the traction motor to drive the traction belt 135 to move. The traction belt 135 is fixedly connected to the stretching assembly 31 and provides power when the stretching assembly 31 moves. The lower end of the stretching assembly 31 is fixedly connected to the traction slider 133. The traction slider 133 is slidably arranged on the traction guide rail 131, and the traction slider 133 guides and limits the moving direction of the stretching assembly 31.

[0046] Further, a cable carrier is provided at the lower end of the stretching assembly 31. The cables through which the control module 70 is electrically connected to the stretching assembly 31 are all arranged inside the cable carrier. When the stretching mechanism moves between the normal-temperature housing and the heating housing 55, the cables arranged inside the cable carrier move together with the stretching assembly 31. The cable carrier protects the cables from being entangled or broken during the movement of the stretching assembly 31, improves the stability of the film stretching device 100 during operation, and reduces the probability of failure of the cables electrically connecting the electrical components.

[0047] As Figures 1 to 7 shown, in an embodiment of the present invention, the support module 10 further includes a lifting assembly 15. The lifting assembly 15 includes a lifting plate 153 and a lifting structure 151. The stretching housing 33 is arranged on the upper side of the lifting plate 153, and the heating housing 55 is arranged at one end of the upper side of the lifting plate 153 away from the stretching housing 33; the lifting structure 151 is clamped between the support assembly 11 and the lifting plate 153. The control module 70 is electrically connected to the lifting structure 151 and is used to control the lifting structure 151 to drive the lifting plate 153 to lift. It can be understood that the lifting structure 151 can be an actuator such as a cylinder or an electric cylinder, and no specific limitation is made thereto again.

[0048] It can be understood that in the in-situ characterization experiment of film stretching, the control module 70 can control the lifting structure 151 electrically connected thereto to drive the lifting plate 153 to lift. The lifting plate 153 enables the heating module 50 and the stretching module 30 arranged thereon to reach a preset height, so that the film to be tested in the film stretching device 100 has a correct spatial position relationship with the relevant characterization equipment used in combination outside the device, which is convenient for the acquisition of data in the in-situ characterization experiment of film stretching, and improves the flexibility and applicability of the film stretching device 100. Correspondingly, magnetic cover plates are arranged around the support assembly 11 and the lifting assembly 15. The plurality of magnetic cover plates enclose the support assembly 11 and the lifting assembly 15. The cover plates adopting the non-screw fastening magnetic installation method do not interfere with the film stretching device 100 during height adjustment, and also facilitate the removal and reinstallation during maintenance and repair.

[0049] In an embodiment of the present invention, the heating assembly 51 includes a main heating element and at least two main blowers. The at least two main blowers and the main heating element are arranged at intervals in the middle of one inner wall side inside the heating housing 55;

[0050] and / or, the heating module 50 further includes an auxiliary heating assembly 53. The auxiliary heating assembly 53 includes an auxiliary blower, an auxiliary heating assembly 53 and an auxiliary air duct. The two ends of the auxiliary air duct are respectively connected to the vertical edge and the center of one inner wall side inside the heating housing 55. The auxiliary heating assembly 53 is arranged inside the auxiliary air duct, and the auxiliary blower is arranged inside the auxiliary air duct. The auxiliary blower is arranged at the side opening of the auxiliary air duct close to the edge of one inner wall side inside the installation housing.

[0051] In the main heating component 51, heat is mainly transferred through forced convection of hot air. The main fan is a multi-wing centrifugal impeller fan. The function of the multi-wing centrifugal impeller fan is to generate a centrifugal air flow to blow over the main heating element, so that the hot air is blown towards the heating area due to forced convection. In a single-stage centrifugal fan, the gas enters the impeller axially. When the gas flows through the impeller, it changes to a radial direction and then enters the diffuser. In the diffuser, the gas changes the flow direction and the cross-sectional area of the pipeline increases to decelerate the air flow. This decelerating effect converts kinetic energy into pressure energy. Therefore, the centrifugal fan generates an air flow radially and blows it towards the main heating element. Two adjacent main fans are arranged oppositely, and the two radial air flows blow against each other to form forced convection. After the convection, the air flow blows into the heating area to jointly heat the space in the inner cavity of the heating housing 55.

[0052] As Figures 1 to 7 shown, in an embodiment of the present invention, the control module 70 includes an electric control cabinet 71, an operation panel 73 and a measurement and control screen 75. The electric control cabinet 71 is arranged on the support assembly 11. A main control board 711 is arranged in the electric control cabinet 71. The stretching assembly 31 is electrically connected to the main control board 711, and the heating assembly 51 is electrically connected to the main control board 711. The operation panel 73 is arranged on the support assembly 11, and the operation panel 73 is electrically connected to the main control board 711. The support assembly 11 further includes a mounting rack. The mounting rack is arranged on one side of the operation panel 73. The measurement and control screen 75 is detachably arranged on the mounting rack, and the measurement and control screen 75 is electrically connected to the main control board 711. In the in-situ characterization experiment of film stretching, the main control board 711 accommodated in the electric control cabinet 71 performs real-time or preset control on the parameters of the movement of each component electrically connected to it. The operation panel 73 is arranged on the support assembly, and the operation panel 73 is signal-connected to the main control board 711. A plurality of operation buttons are arranged on the operation panel 73, and the preset parameters can be manually adjusted within a preset range through the operation buttons. Before the in-situ characterization experiment of film stretching, the measurement and control screen 75 is detachably installed on the mounting rack on one side of the operation panel 73 of the support assembly 11. The measurement and control screen 75 is signal-connected to the main control board 711 and displays the parameters obtained by the main control board 711 and the experimental data on the screen. It should be noted that the measurement and control screen 75 in the present invention can be remotely controlled by installing a remote control program. The main control board 711 in the measurement and control screen 75, the operation panel 73 and the electric control cabinet 71 provide multiple operation methods for experimental personnel to conduct experiments, and display all the data obtained from the experiments and the data required for control on the measurement and control screen 75, making the whole experimental process visual and improving the accuracy and efficiency of the experiment.

[0053] On the other hand, the electric control cabinet 71 is installed in the support assembly 11 through the electric control cabinet 71 slide rail. With such a setting, the electric control cabinet 71 can be slid out from the support assembly 11, which provides convenience for the processes of installing, testing, repairing and maintaining the main control board 711.

[0054] Optionally, the film stretching device 100 further includes a vision module 90. The vision module 90 includes a high-speed camera 91 and a video acquisition system 93. The support assembly is provided with a vision mounting bracket. One end of the vision mounting bracket facing away from the support assembly extends into the heating housing 55. The high-speed camera 91 is slidably connected to the vision mounting bracket and can slide along the vision mounting bracket into the heating housing 55. The video acquisition system 93 is arranged on the vision mounting bracket. The high-speed camera 91 and the video acquisition system 93 are electrically connected to the main control board 711. The high-speed camera 91 extending into the heating housing 55 and the corresponding video acquisition system 93 can perform characterization detection on the film to be tested in the heating housing 55 and collect images during the heating process. The collected information is transmitted to the main control board 711 electrically connected to the high-speed camera 91 and the video acquisition system 93. The main control board 711 then processes the information and displays it on the measurement and control screen 75, so that the state of the film to be tested in the heating housing 55 during the experiment can be clearly displayed in real time, improving the accuracy and efficiency of the experiment.

[0055] As Figures 1 to 8 shown, in an embodiment of the present invention, the stretching housing 33 is provided with a sample operation window 331, and the heating housing 55 is provided with a detection window 551. The film stretching device 100 further includes an incident light source 104. The incident light source 104 is arranged on a side of the stretching housing 33 facing away from the sample operation window 331 and is used to emit light to pass through the central area enclosed by the stretching assembly 31 and reach the sample operation window 331. It can be understood that the film to be tested is correspondingly arranged on the stretching housing 33 through the test space enclosed by the cross-shaped stretching frame 311. The installation and collection of samples during the experiment can be carried out through the sample operation window 331 without disassembling and assembling the entire stretching housing 33, improving the efficiency and convenience of the test. Similarly, the in-situ characterization experiment of film stretching at room temperature can be carried out in the corresponding stretching housing 33. At this time, relevant information during the experiment needs to be obtained through the sample operation window 331. Correspondingly, an incident light source 104 is arranged on a side of the stretching housing 33 facing away from the sample operation window 331. The light of the incident light source 104 can pass through the stretched film fixed in the test space and reach the sample operation window 331, and the characterization information required for the experiment can be indirectly obtained through the changes generated by the incident light passing through the film.

[0056] Furthermore, the film stretching device 100 further includes a wide-angle X-ray scattering detector 103. The wide-angle X-ray scattering detector 103 is correspondingly arranged on a side of the sample operation window 331 facing away from the incident light source 104. The wide-angle X-ray scattering detector 103 is electrically connected to the main control board 711;

[0057] And / or, the film stretching device 100 further includes a small-angle X-ray scattering detector 101, which is correspondingly arranged on the side of the sample operation window 331 away from the incident light source 104, and the small-angle X-ray scattering detector 101 is electrically connected to the main control board 711;

[0059] And / or, the film stretching device 100 further includes a vacuum system 105, which is correspondingly arranged on the side of the sample operation window 331 away from the incident light source 104.

[0060] It should be noted that the X-ray scattering instrument is an analytical instrument widely used in the field of materials. Its working principle is to irradiate the sample with X-rays and measure the scattering angles of the scattered X-rays that appear in the sample to obtain a wide range of information about the structure and properties of the sample. It can be understood that different properties of the sample will result in different scattering angles of the scattered X-rays. The wide-angle X-ray scattering detector 103, small-angle X-ray scattering detector 101, and ultra-small-angle X-ray scattering detector 102 correspondingly set for different scattering angles can obtain characterization information of the thin film to be measured at different detectable scales. The film stretching device 100 can be combined with the above three different characterization devices to obtain the characterization information of the thin film to be measured, improving the accuracy of the in-situ characterization experiment of film stretching. Further, in order to exclude the interference of air on the test instrument, a vacuum system 105 is introduced and the characterization device is arranged in the vacuum system 105, which can better exclude the influencing factors of the environment and achieve higher test accuracy and more accurate experimental results.
