Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized.
[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] like Figure 1 As shown, an embodiment of the present application provides an automatic thickness gauge for polymer films, comprising a test bench 1, a traction mechanism 2, a magnetic mechanism 3 and a measuring instrument 4; the test bench 1 is used to provide a platform for measuring the thickness of the polymer film to be tested; the traction mechanism 2 is installed at one end of the test bench 1, and is used to pull the polymer film to be tested to the test bench 1; the magnetic mechanism 3 is used to adsorb the polymer film to be tested to the traction mechanism 2; the measuring instrument 4 is installed in the middle of the test bench 1, and is used to measure the thickness of the polymer film to be tested.
[0030] The polymer film to be tested is attracted to the traction mechanism 2 by the magnetic mechanism 3, and then the traction mechanism 2 pulls the polymer film to the test table 1. The thickness of the polymer film to be tested is measured by the measuring instrument 4 on the test table 1. This can replace the tester's measurement, allowing for long-term testing and facilitating long-term measurement. This reduces the problem of manual fatigue and errors caused by long-term measurement. The test instrument is simple and easy to operate.
[0031] In some embodiments, the test bench 1 includes a glass table top, which is used to provide a platform for measuring the thickness of the polymer film to be tested; the traction mechanism 2 is installed on the front side of the glass table top.
[0032] In some embodiments, the traction mechanism 2 includes an active roller, and the active roller is used to pull the polymer film to be tested to the glass table by rotating.
[0033] In some embodiments, the magnetic mechanism 3 includes an electromagnet 31 and an iron block 32 ; the electromagnet 31 is installed on the traction mechanism 2 , and the iron block 32 is installed on the back of the glass table top.
[0034] In some embodiments, the measuring instrument 4 includes a sensor, a pneumatic clamp, a telescopic device, and a motor.
[0035] In some embodiments, a calculation controller is further included, which is connected to the traction mechanism 2 and is used to calculate the number of revolutions of the active roller and control the start and stop of the active roller.
[0036] In some embodiments, a flattening roller 5 is further included. The flattening roller 5 is installed at the other end of the test bench 1 and is used to flatten the polymer film to be tested.
[0037] In some embodiments, a light source 6 is further included. The light source 6 is installed below the glass table and is used to illuminate the glass table.
[0038] In some embodiments, two correcting rollers 7 are further included. The two correcting rollers 7 are installed at the other end of the test bench 1 and are respectively connected to the two sides of the polymer film to be tested; the surface of the correcting roller 7 is engraved with diagonal lines along a specific direction and is covered with a rubber sleeve.
[0039] In some embodiments, a clamping roller 8 is further included. The clamping roller 8 is installed at the other end of the test bench 1 and is used to clamp the polymer film to be tested.
[0040] Place the cut film on the test bench and press the start button to begin measurement. The active roller can move up and down. When testing begins, the roller moves downward. When the distance is appropriate, the electromagnet on the roller is energized, magnetically attracting the iron block and locking the film onto the roller. The roller then begins to rotate. A computer controller calculates the number of revolutions and automatically stops and rotates at intervals of a certain number of centimeters, using a computer-controlled setting.
[0041] There is a flattening roller on the right side of the measuring instrument, which can flatten the film during measurement, keep the surface of the film flat, and ensure that the film is measured accurately and the surface is flat. Figure 2 As shown, there are two correcting rollers with diagonal lines in a specific direction under the flattening roller. The inside of the roller is similar to the flattening roller, but the lines are in a specific direction. The outside is an airtight rubber sleeve with a certain elasticity, which is connected to both sides of the film.
[0042] During each test, a light source shines from the bottom of the test bench. The system determines whether the film has deviated from one side by calculating the opaque area and the distance between the two sides. If one side is too short, a vacuum is drawn into the corresponding rubber sleeve, causing the film to move according to the corresponding pattern on the roller, thus correcting the deviation. If the film remains in the corrected position, a certain pressure is applied to the rubber sleeve. This pressure is measured using a pressure measuring device to determine a value, such as 1 MPa, which smoothes the correction roller.
[0043] The instrument also features a web-correcting system that uses a web-correcting roller that moves left and right. When the film needs to deflect upward, the web-correcting roller retracts while the other web-correcting roller extends outward. These two methods ensure that the film's movement is straight.
[0044] Each time the active roller stops, the measuring instrument descends and measures within 1 second. The reading is output, held, and fed into the CPU, which performs calculations to ensure data deviations are manageable. If an abnormal value is detected, the measuring instrument remeasures. If the test data is still abnormal, an alarm sounds. The tester then conducts an inspection. If it is not properly placed, the tester re-arranges the measurement and re-measures the instrument on the computer. If the result is correct, the user clicks "Output Result" and the data is exported to external software such as Excel. The measurement system then organizes the feedback data and creates relevant quality graphics, such as quality control charts.
[0045] Repeat the above operation. When the test reading is 0, the instrument ends the program, the active roller moves to the left, and then quickly turns in the opposite direction. After the film is unloaded, the active roller moves to the initial position and the electromagnet is disconnected. The clamping roller can be considered to be clamped in two directions, or as Figure 3 There are two nip rollers in both directions shown.
[0046] The polymer film automatic thickness gauge provided in the embodiments of the present application uses an electromagnet to clamp the film and utilizes active rollers and flattening rollers to ensure the film is flat. This instrument can replace a human tester in measuring, allowing for extended testing and facilitating long-term measurements. This eliminates the problem of manual fatigue and errors caused by prolonged measurement. The test instrument is simple and easy to operate.
