Description

Technical Field

[0001] The present invention relates to the technical field of polarizer detection, and in particular to a testing device and a testing method for the peeling force of an outer film of a polarizer. Background Art

[0002] As the core material of liquid crystal display panels, polarizers can convert naturally emitted light into polarized light, thereby forming an image on the liquid crystal panel. Polarizers are composed of a protective film, upper triacetyl cellulose (TAC), polyvinyl alcohol (PVA) elements, lower TAC, pressure-sensitive adhesive (PSA) and release film. During the production and processing process, the front process forms a protective film-upper TAC-PVA-lower TAC structure; the middle process performs a release film bonding process and forms a protective film-upper TAC-PVA-lower TAC-PSA-release film structure; the back process cuts the product obtained from the middle process into a certain size. After the polarizer is bonded to the liquid crystal panel, its outer protective film and the outer layer of the release film will eventually be peeled off to form an effective layer structure of upper TAC-PVA-lower TAC-pressure-sensitive adhesive.

[0003] During the peeling process of the outer protective film and the release film, the peeling force of the protective film and the release film will be required to be controlled within a certain range to ensure the use of downstream panel manufacturers. This requires timely sampling and testing of each roll of polarizer after production to ensure that the polarizer product peeling force performance is qualified. In the polarizer quality inspection process, the 180° peeling force test is a major method for testing the peeling force performance of the outer layer of the polarizer. Usually, three products at the same position are tested and the average value is taken. Therefore, a large number of samples need to be tested.

[0004] When the roll material production is completed, the quality inspection personnel are required to cut three pieces of products from different positions of each roll material as peeling force test samples, and test the peeling force of the protective film and the release film one by one, so as to control quality problems. The existing testing process requires clamping, testing, disassembly and replacement of multiple test samples one by one. The whole testing process will consume a lot of time. However, with the gradual expansion of factory production capacity and the increase in production speed, a kilometer-long polarizer roll material can be produced in only one hour, and the front process and the middle process are carried out at the same time. Therefore, the existing peeling force detection efficiency is difficult to ensure timely detection of the product's peeling force performance. Without test data, it is impossible to determine whether the corresponding roll material meets the quality standards for entering the next process. In addition, the existing detection method requires the full intervention of the detection personnel throughout the entire detection process, and it is difficult to perform other tasks such as appearance inspection. If the corresponding roll material has been put into the next process before the test analysis results come out, serious quality problems may occur.

[0005] SUMMARY OF THE INVENTION

[0006] The technical problem solved by the present invention is: with the gradual expansion of factory production capacity and the increase in the production speed of polarizer rolls, the existing polarizer peeling force detection method is relatively time-consuming, and it is difficult to ensure timely detection of the product's peeling force performance. In addition, the entire detection process requires full intervention by detection personnel, making it difficult to perform other tasks such as appearance detection.

[0048] See also Figure 1-2 The present invention is a testing device for the peeling force of the outer layer 10 of the polarizer, comprising: an operating table 19, a slide rail 2, a track slider 3, a stage 4, a rotating wheel 6, a rotating plate 7, a clamping assembly 18 and a corresponding driving mechanism. The operating table 19 is used as the main structure of the device, which can be fixedly set on the ground or the bearing structure. The operating table 19 can be provided with an operating panel 20, a control panel and a controller (control system) for displaying including but not limited to the operating process, operating instructions and test process of the device. The operating table 19 may include a controller (control system), and the controller (control system) may be a CPU processor, a chip structure controller or a PLC control system, etc. So as to be used to control the automation process of the entire device. The control process can be achieved by controlling the action of the relevant driving mechanism.

[0049] See also Figure 1-2In one embodiment of the present invention, the stage 4 is movably arranged on the operating table 19 for carrying the sample to be tested, and a plurality of fixing clamps 5 are fixedly arranged on the stage 4, and the plurality of fixing clamps 5 are arranged in sequence along the extension direction of the slide rail 2; by providing a plurality of fixing clamps 5, a plurality of samples can be clamped at one time, and the detection action can be completed in sequence in the subsequent process. The number and grouping of the fixing clamps 5 can be specifically set according to the usage. Since three samples need to be detected at each position during the actual detection, and the average value is calculated as the detection result, it is preferred that the fixing clamps 5 are grouped into three groups so as to clamp and fix three samples at the same position; the common method of coil sampling is to sample the left, middle and right positions of the coil tail respectively, so the number of groups of fixing clamps 5 on the stage 4 can be set to three groups. It can also be set to more. In actual use, the samples of a single roll of coil are clamped at the same time and then detected in sequence.

[0050] See also Figure 1-2 In one embodiment of the present invention, the movement of the loading platform 4 can be achieved by a linear drive assembly. In order to ensure the stability of the loading platform 4 during movement, a slide rail 2 structure is provided between the loading platform 4 and the operating table 19. Specifically, the slide rail 2 structure includes a slide rail 2 and a track slider 3, and the slide rail 2 is fixedly arranged on the operating table 19; a mounting frame 1 can be fixedly arranged on the operating table 19, and the slide rail 2 can be fixedly arranged on the mounting frame 1 to achieve a fixed connection with the operating table 19, and the slide rail 2 can maintain a certain height space. The track slider 3 is slidably connected to the slide rail 2; the loading platform 4 is fixedly connected to the track slider 3; the first linear drive assembly is used to drive the slider to move linearly along the slide rail 2; thereby driving the loading platform 4 to move in a linear direction. The action process of the first linear drive assembly can be controlled by a PLC control system.

[0051] See also Figure 1-2In one embodiment of the present invention, the rotating wheel 6 is rotatably connected to the stage 4 and the rotating axis of the rotating wheel 6 is consistent with the extension direction of the slide rail 2; the rotating plate 7 is fixedly connected to the rotating wheel 6, and the rotating power source is used to drive the rotating wheel 6 to rotate; a film support frame can be fixedly arranged on the stage 4, and the rotating wheel 6 is arranged at one end of the film support frame away from the stage 4, so that the rotating wheel 6 has a certain height space. The rotating power source can be a rotating motor and can be connected to a PLC control system so as to be controlled by the PLC control system. When in use, after the polarizer is clamped and fixed, its lower end is in a vertical state, and the initial state of the rotating plate 7 is in a horizontal state. By driving the rotating wheel 6 to rotate, the rotating plate 7 is driven to rotate 90°, and then the rotating plate 7 changes from the horizontal state to the vertical state. In this process, the upper end of the rotating plate 7 can contact the inner side of the protective film, thereby lifting the lower end of the protective film, which is convenient for the subsequent clamping of the clamping assembly 18. Furthermore, the end of the rotating plate 7 away from the rotating wheel 6 is tilted to form a contact portion, and the tip of the rotating plate 7 is located on the side away from the fixing fixture 5. In this way, the rotating plate 7 makes linear contact with the protective film through the contact portion, which can reduce the contact area between the top of the rotating plate 7 and the glue on the inner side of the protective film to prevent adhesion and affect the normal operation of the device.

[0052] See also Figure 1-2 In one embodiment of the present invention, the clamping assembly 18 is used to clamp the protective film to be peeled off on the polarizer, and moves the protective film to be peeled off under the driving action of the driving mechanism so as to detect the peeling force. The clamping assembly 18 can be a manipulator clamping structure or other clamping structures. As an example, the clamping assembly 18 includes two relatively arranged clamping jaws and a clamping power source for driving the two clamping jaws to clamp; the two clamping jaws can be arranged in parallel, and the two clamping jaws are driven to approach / move away from each other by a linear driving structure to achieve a clamping action. The clamping jaws can also be connected by rotation, and then the ends of the two clamping jaws are driven to approach each other by a corresponding driving structure to achieve a clamping action. The clamping jaws can be connected to a PLC control system so as to be controlled by a PLC control system. Further, a clamping protrusion is provided on the inner side of the clamping jaw (i.e., the opposite surface of the two clamping jaws). By providing a clamping protrusion, the clamping and moving effect of the clamping jaw on the protective film is increased, and the contact surface is reduced, so as to ensure that the outer layer 10 of the polarizer can be tightly clamped without slipping, and at the same time, it does not adhere to the outer layer 10 of the polarizer after being released. Furthermore, an arc portion is provided at one end of the clamping jaw close to the fixing fixture 5. In the process of the clamping assembly 18 moving toward the polarizer, the arc portion can play a guiding role. Even if the height position of the protective film and the clamping assembly 18 deviates, the clamping assembly 18 can stably clamp the protective film under the guiding effect of the arc portion. At the same time, the arc portion can ensure that the sample will not be damaged during the 180° peeling test.

[0053] See also Figure 1-2 In one embodiment of the present invention, the driving mechanism for driving the clamping assembly 18 to move may include a second linear driving assembly and a third linear driving assembly, wherein the second linear driving assembly is used to drive the clamping assembly 18 to approach / move away from the operating table 19; and the third linear driving assembly is used to drive the clamping assembly 18 to approach / move away from the fixing fixture 5. The second linear driving assembly and the third linear driving assembly are respectively connected to the PLC control system so as to perform motion control through the PLC control system. The above-mentioned linear driving assemblies (first linear driving assembly, second linear driving assembly, third linear driving assembly) can be a cylinder / hydraulic cylinder structure, a linear motor, a ball screw driving structure or other driving structures capable of realizing linear reciprocating movement.

[0054] See also Figure 1-2 In one embodiment of the present invention, a base 17 is fixedly provided on the operating table 19, and the second linear drive assembly is fixedly installed on the base 17. The second linear drive assembly may include a vertical screw motor 16, a vertical electric screw 11 and a vertical slider 14. The vertical slider 14 is threadedly sleeved on the vertical electric screw 11, and can be used to limit the rotation of the vertical slider 14 through a guide rail, a support rod or other structure. When in use, the vertical screw motor 16 drives the vertical screw to rotate, thereby driving the vertical slider 14 to move up and down. The second linear drive assembly is horizontally fixedly installed on the vertical slider 14, and may include a horizontal screw motor 15, a horizontal electric screw 13 and a horizontal slider 12. The clamping assembly 18 is fixedly arranged on the horizontal slider 12 to achieve horizontal movement of the clamping assembly 18. In addition, the third linear drive assembly may also be arranged on the base 17, and the second linear drive assembly may be arranged on the second linear drive assembly. The above is only an example and is not a limitation on the corresponding structure.

[0055] See also Figure 1-2 The present invention also provides a method for testing the peeling force of the outer layer 10 of the polarizer based on the above-mentioned testing device, comprising the following steps:

[0056] Step 1. Sampling: When the production of (a roll) of the target process (such as the front process or the middle process) is completed, the corresponding roll is sampled. The sampling position and quantity can be set according to the actual production situation. As an example, the samples can be taken from the left, middle and right sides of the end of the roll, and the samples at each position can be cut into three pieces of the same shape; at this time, a total of nine samples to be tested are obtained.

[0057] Step 2. Lamination: Laminate the cut samples to the glass plate 8 and mark them. The glass plate 8 is equivalent to the liquid crystal panel. Laminating the polarizer sample to the glass plate 8 is equivalent to laminating it to the liquid crystal panel. The peeling force can be accurately tested. At the same time, the glass plate 8 can also be easily clamped and fixed by the fixing fixture 5. The marking is to facilitate the distinction, data correspondence and possible traceability in the later stage. Each polarizer to be tested should keep the same size, and the end of it after laminating to the glass plate 8 should also be basically the same distance from the glass plate 8.

[0058] Step 3. Clamping: The glass plates 8 with the samples attached are clamped and fixed on the fixing fixtures 5 respectively. From the first fixing fixture 5 to the ninth fixing fixture 5, a glass plate 8 corresponding to the sample to be tested is fixed respectively. These nine samples are tested in the same batch, which can effectively avoid confusion. The outer layer 10 of the polarizer (i.e., the protective film, that is, the layer to be tested. The test layer can also be a release film. It mainly depends on which outer layer of the film needs to be tested for peeling force in the sampling process. For example, the protective film needs to be tested after the production of the front process is completed, and the release film and protective film peeling force values ​​of the polarizer product completed in the middle process need to be tested. The release film and the protective film both belong to the outer layer 10 of the polarizer involved in the present invention) is longer than the inner layer 9 of the polarizer. During the clamping process, it is necessary to ensure that the outer layer 10 of the polarizer is located on the side close to the clamping assembly 18, and the end of the outer layer 10 of the polarizer that exceeds the inner layer 9 of the polarizer is located at the lower end, so as to facilitate subsequent clamping and glass action.

[0059] Step 4. Positioning: Ensure that the position of the first fixing fixture 5 corresponds to the position of the clamping assembly 18, and drive the rotating wheel 6 to rotate by the rotating power source, and drive the rotating plate 7 to rotate, and the rotating plate 7 changes from the horizontal state ( Figure 1 90° clockwise) to a vertical position (such as Figure 1 ), the upper end of the rotating plate 7 contacts with the polarizer outer layer 10 and lifts up the lower end of the polarizer outer layer 10; at this time, the lower end of the polarizer outer layer 10 will be in a horizontal state, so that the subsequent clamping action of the clamping assembly 18 can proceed smoothly.

[0060] Step 5. Clamping: The second linear drive assembly drives the clamping assembly 18 to move to a position where the height of the rotating plate 7 is consistent (this position can be used as the initial position of the clamping assembly 18 in terms of height), and then the third linear drive assembly drives the clamping assembly 18 to move horizontally to the end of the outer layer 10 of the polarizer (after being lifted by the rotating plate 7) and clamp it. At this time, the rotating plate 7 returns from the vertical state to the horizontal state ( Figure 1 In the figure, the clamping assembly 18 is rotated 90° counterclockwise to avoid affecting the subsequent movement of the clamping assembly 18. Meanwhile, the clamping assembly 18 continues to move until it is located below the polarizer (protective film to be peeled off);

[0061] Step 6. Peeling: The second linear drive assembly drives the clamping assembly 18 to move upward at a uniform speed to perform a 180° protective film peeling action, completing the peeling force test at the position of the first fixed fixture 5, and recording the peeling force data. The peeling force recording process can be detected by setting a sensor and uploaded to a processor or control system, and then calculated and analyzed by the control system, and the data can be retained for subsequent analysis and call;

[0062] Step 7. After the test of the sample at the position of the first fixed fixture 5 is completed (i.e., the first test), the equipment is reset, and then the stage 4 moves once, and the second fixed fixture 5 moves to the position to be tested (consistent with the lateral position of the clamping assembly 18). In this way, steps 4-6 are repeated to sequentially complete the peeling force test and data recording of the samples fixed on the subsequent fixed fixtures 5. After each test is completed, during the reset process, the clamping assembly 18 is opened to loosen the peeled waste film and drop it onto the operating table 19. The waste film can be stored when the subsequent staff disassembles and assembles the tested samples, or a storage box can be set on the operating table 19. After completing a sample test, the clamping assembly 18 moves to the top of the storage box and then loosens it, so that the waste film falls into the storage box.

[0063] See also Figure 1-2 In one embodiment of the present invention, specifically, when the device is used, the device can start the detection process after fixing the first sample, and carry out the subsequent sample clamping and fixing work at the same time, so as to save time to the greatest extent. It is also possible to start the device for the detection process after all samples of a batch are clamped. The action process can be automatically carried out by the control system, during which the staff can carry out other work, such as appearance inspection, inspection data analysis, etc. The samples of the same coil are inspected at one time in a batch, and the inspection data can be obtained in time to provide an analysis basis for whether the product can flow into the next process. At the same time, it is not easy to cause confusion or corresponding errors between samples or between samples and coils.

[0064] Working principle of the present invention: By providing multiple groups of fixing clamps 5, the device can quickly and automatically complete the peeling force detection of multiple samples after clamping multiple samples at one time, greatly improving the efficiency of peeling force testing, and can complete the peeling force detection in time after each roll of coil is produced, providing a basis for quality analysis and avoiding possible quality problems. At the same time, the fixing clamps 5 are set to correspond to the number of positions used, so that the samples of a coil can be tested in one batch, greatly reducing the risk of confusion. Each group of fixing clamps 5 includes three, which is convenient for calculating and analyzing the test results. After the device fixes the glass plate 8 with the fixing clamps 5, there is no need for manual intervention, and each roll of sample can be tested once, and the test results can be waited for. During this period, the staff can do other work, which improves work efficiency.

Laminating: Laminating the cut samples to the glass plates (8) respectively and marking them; Step 3. Clamping: The glass plates (8) bonded with the samples are clamped and fixed on the fixing fixtures (5) respectively. During the clamping process, the outer layer (10) of the polarizer is ensured to be located on the side close to the clamping assembly (18), and the end of the outer layer (10) of the polarizer that extends beyond the inner layer (9) of the polarizer is located at the lower end; Step 4. Positioning: ensure that the position of the first fixing fixture (5) corresponds to the position of the clamping assembly (18), drive the rotating wheel (6) to rotate by rotating the power source, and drive the rotating plate (7) to rotate, the rotating plate (7) rotates 90° from the horizontal state to the vertical state, the upper end of the rotating plate (7) contacts the outer layer of the polarizer (10), and lifts the lower end of the outer layer of the polarizer (10); Step 5. Clamping: The clamping assembly (18) is driven by the second linear drive assembly to move to a position where the height of the rotating plate (7) is consistent, and then the clamping assembly (18) is driven by the third linear drive assembly to move horizontally to the position of the lower end of the outer layer (10) of the polarizer and clamp it. At this time, the rotating plate (7) returns from a vertical state to a horizontal state, and at the same time, the clamping assembly (18) continues to move until it is located below the polarizer; Step 6. Peeling: The second linear drive assembly drives the clamping assembly (18) to move upward at a constant speed to perform 180° peeling, completing the peeling force test at the position of the first fixed fixture (5), and recording the peeling force data at the same time; Step 7. Repeat steps 4-6 to sequentially complete the peeling force test and data recording of the samples fixed on the subsequent fixing fixture (5).
