Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tensile testing, and specifically discloses a kind of optical transparent adhesive tensile testing equipment. BACKGROUND

[0002] As a kind of key optical adhesive material, optical transparent adhesive (OCA) is widely used in the lamination of touch screen, display module, flexible electronic device and other fields. Its performance reliability directly determines the display effect, durability and service life of terminal product. Among them, the tensile strength, ductility, creep resistance and other mechanical properties of the gel in different directions are crucial evaluation indexes. Therefore, in the research and development and quality control link, the optical transparent adhesive must be tested by tensile test in multiple angles and multiple working conditions.

[0003] Optical transparent adhesive has strong surface adhesion, which is an advantage in application, but a huge challenge in test preparation stage. When installing the rolled adhesive tape sample on the test equipment, especially when it needs to be inserted and fixed on the clamp or roller, the operator is extremely difficult to straighten and align due to the adhesion of the gel itself. The gel is extremely easy to stick with the equipment itself, clamp or operating tool, which causes the sample to wrinkle, fold, contaminate or generate initial internal stress, which seriously affects the initial state of the test sample, so that the subsequent test data is distorted and cannot reflect the real performance of the material.

[0004] Traditional tensile tester can only perform unidirectional (such as 0° or 90°) tensile test. In actual application, especially in flexible foldable devices, optical transparent adhesive may bear complex stress from different directions. Single test angle cannot fully simulate these complex working conditions, resulting in limited test results, which cannot provide sufficient data support for material design and application.

[0005] Therefore, the present application proposes a kind of optical transparent adhesive tensile testing equipment to solve the above defects. SUMMARY

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1-8 The optical transparent adhesive tensile testing device shown includes a testing platform 1, a testing frame 2, a pressure sensor 3, and an X-axis drive mechanism 4. The testing frame 2 is fixedly installed on the upper surface of one side of the testing platform 1. A movable stage 13 is connected to the inside of the testing frame 2 through a hydraulic mechanism. A fixed plate 9 is connected to one end of the movable stage 13 through a rotating mechanism. An upper clamping member is provided on one side of the outer surface of the fixed plate 9. The pressure sensor 3 is located on one side of the testing frame 2. The X-axis drive mechanism 4 is located on one side of the outer wall of the testing platform 1. A slider 5 is installed on the outside of the X-axis drive mechanism 4. A slide table 23 is fixedly installed above the slider 5. A lower clamping member is provided on the upper surface of the slide table 23. A base 15 is fixedly installed on one side of the outer wall of the slide table 23. A support seat 7 is connected to the upper surface of one side of the base 15 through a telescopic mechanism. A guide rod 31 is fixedly installed on one side of the outer wall of the support seat 7. The guide rod 31 is hollow inside, and a slip ring 17 is slidably arranged on the outside of the guide rod 31. An adhesive guide is provided below the slip ring 17.

[0029] In this embodiment, the testing frame 2 is fixed to one side of the testing table 1, and the moving table 13 is suspended by a hydraulic mechanism. The moving table 13 is connected to the fixed plate 9 and the upper clamping part by means of a rotating mechanism to realize the fixing of the upper end of the colloid and the angle adjustment.

[0030] The X-axis drive mechanism 4 is mounted on the outer wall of the testing stage 1. It drives the slide stage 23 and the lower clamping component to move via the slider 5, thereby achieving the purpose of stretching the lower end of the colloid. The pressure detection sensor 3 collects mechanical data in real time during the stretching process and connects to an external detection and control system to obtain the stretching test data. This is a common existing technology and will not be described in detail.

[0031] The hydraulic mechanism includes a first hydraulic cylinder 14 fixedly installed inside the testing frame 2. Guide rods are installed on both sides inside the testing frame 2. The telescopic end of the first hydraulic cylinder 14 is fixedly connected to the lower surface of the moving table 13. The two sides inside the moving table 13 are slidably connected to the guide rods.

[0032] In this embodiment, the first hydraulic cylinder 14 is fixed inside the testing frame 2, and its telescopic end is rigidly connected to the lower surface of the moving stage 13. The guide rods on both sides of the testing frame 2 pass through the interior of the moving stage 13 and form a sliding fit. During operation, the first hydraulic cylinder 14 drives the moving stage 13 to move vertically up and down along the guide rods through telescopic movement, causing the upper clamping part and the upper end of the colloid to move synchronously. It can achieve vertical stretching alone, or complete multi-directional compound stretching in conjunction with the X-axis drive mechanism 4. The guide rods ensure that the moving stage 13 moves smoothly without deviation, avoids uneven force on the colloid during stretching, and improves the consistency of test data.

[0033] The X-axis drive mechanism 4 consists of a servo motor, a lead screw, a lead screw sleeve, and a slide rail.

[0034] The rotating mechanism includes a motor 8 fixedly installed on the outer wall of the rear end of the moving platform 13. The output shaft of the motor 8 is fixedly connected to one side of the fixed disk 9. A gear 30 is provided at the rear end of the fixed disk 9. A second hydraulic cylinder 21 is fixedly installed inside the upper part of the moving platform 13. A pin 22 is fixedly installed at the telescopic end of the second hydraulic cylinder 21. A slot for fitting the gear 30 is opened on one side inside the pin 22.

[0035] In this embodiment, the motor 8 is fixed to the outer wall of the rear end of the moving platform 13, and the output shaft is directly connected to the fixed disk 9 to drive the fixed disk 9 to rotate and adjust the stretching angle.

[0036] During angle adjustment, the second hydraulic cylinder 21 retracts, causing the pin 22 to disengage from the gear plate 30. The motor 8 drives the fixed plate 9 and the upper clamping part to rotate to the target angle (such as 45°, 90°, etc.). Then, the second hydraulic cylinder 21 extends, and the pin 22 engages with the gear plate 30 to lock. This structure can precisely adjust the stretching angle of the colloid, simulate the complex stress direction in actual applications, solve the limitations of unidirectional testing of traditional equipment, and make the test results more consistent with actual use scenarios.

[0037] The upper clamping component includes a shaft 12 fixedly installed on the outer surface of one side of the fixed plate 9. A winding shaft 11 is fitted in the middle of the shaft 12. The shaft 12 is a threaded rod, and threaded abutment cylinders 10 are threadedly connected to both ends of the shaft 12.

[0038] In this embodiment, during installation, the take-up shaft 11 carrying the optically transparent adhesive is fitted onto the shaft 12. The take-up shaft 11 is then quickly positioned and fixed by tightening the threaded abutments 10 at both ends, which abut against both sides. The adjustable threaded abutments 10 accommodate take-up shafts 11 of different diameters, offering strong versatility. Simultaneously, the symmetrical abutment design ensures smooth rotation of the take-up shaft 11, preventing jamming or displacement during adhesive release, preventing initial internal stress in the adhesive, and ensuring the consistency of the initial state of the test samples.

[0039] The lower clamping component includes a fixed seat 24 and a movable seat 27. The fixed seat 24 is fixedly installed on one side of the upper surface of the slide table 23. A third hydraulic cylinder 26 is provided at the rear end of the movable seat 27. The lower part of the third hydraulic cylinder 26 is connected to one side of the outer wall of the slide table 23 through a fixedly installed bracket 25. Abutment blocks 28 are provided on the sides of the fixed seat 24 and the movable seat 27 that are close to each other.

[0040] In this embodiment, when clamping the lower end of the colloid, the third hydraulic cylinder 26 pushes the movable seat 27 to move towards the fixed seat 24, and the abutment block 28 gently clamps the lower end of the colloid from both sides, which not only ensures a firm clamping but also avoids local stress concentration. Moreover, this structure has high clamping efficiency, is suitable for colloid samples of different widths, and ensures that the lower end of the colloid does not loosen or shift during the stretching process, thereby improving the accuracy of the test data.

[0041] The telescopic mechanism includes a housing 6 fixedly installed on the upper surface of one side of the base 15. An electric push cylinder 34 is fixedly installed on the bottom wall of the inner side of the housing 6. The telescopic end of the electric push cylinder 34 is fixedly connected to the lower surface of the support base 7. A water tank 16 is fixedly installed on the upper surface of the base 15 and on the side close to the housing 6.

[0042] In this embodiment, during operation, the electric push cylinder 34 drives the support base 7 and the upper guide rod 31 and the adhesive guide to rise and fall by telescopic drive. The guide position can be adjusted according to the release height of the adhesive to ensure that the adhesive always extends smoothly in the horizontal direction.

[0043] The water tank 16 is used to hold the cleaning liquid, which provides a guarantee for the subsequent cleaning of the bidirectional scraper 20, avoids the colloid residue on the scraper from affecting the next use, and improves the ease of maintenance and service life of the equipment.

[0044] The adhesive guide includes a vertical rod 37 fixedly installed below the slip ring 17. A sleeve block is slidably installed on the outside of the vertical rod 37. Mounting blocks 35 are fixedly connected to both sides of the outer wall of the sleeve block. A rotating shaft 36 is fixedly inserted inside the mounting block 35. A moving rod 33 is rotatably installed in the middle of the outside of the rotating shaft 36. Abutment rings 32 are slidably installed at both ends of the moving rod 33.

[0045] In this embodiment, when guiding the colloid, the rotating moving rod 33 is aligned with the direction of colloid extension, and the abutment ring 32 contacts both sides of the colloid. Due to the small contact area and smooth surface, colloid adhesion can be avoided. The sliding of the sleeve along the vertical rod 37 can finely adjust the height of the moving rod 33, and the sliding of the abutment ring 32 can adapt to colloids of different widths, ensuring that the colloid is laid flat and wrinkle-free from all angles, and eliminating the influence of initial stress on the test results.

[0046] The lower end of the vertical rod 37 is externally threaded to a threaded sleeve 29, and a bidirectional scraper 20 is fixedly installed inside the threaded sleeve 29. A connecting rod is fixedly installed on one side of the outer wall of the slip ring 17, and an L-shaped clamping block 18 is fixedly installed on one side of the outer wall of the support base 7. A cylinder 19 is fixedly installed inside the L-shaped clamping block 18, and the telescopic end of the cylinder 19 is fixedly connected to the outer wall of the connecting rod.

[0047] In this embodiment, after the test is completed, the electric push cylinder 34 drives the support base 7 to descend, aligning the bidirectional scraper 20 with the abutment block 28 of the lower clamping member. The cylinder 19 drives the slip ring 17 to move along the guide rod 31, causing the bidirectional scraper 20 to scrape off the adhesive residue on the surface of the abutment block 28. The threaded sleeve 29 facilitates the disassembly and replacement of the bidirectional scraper 20. The bidirectional design can scrape off the residue on both sides of the abutment block 28 at once, resulting in high cleaning efficiency. After scraping, the bidirectional scraper 20 can be submerged in the water tank 16 for cleaning as the support base 7 descends, avoiding the accumulation of residual adhesive, ensuring the accuracy of subsequent tests, and reducing the difficulty of equipment maintenance.

[0048] Working principle: The take-up shaft 11 carrying the optically transparent adhesive sample is mounted on the shaft 12 on one side of the fixed plate 9, and fixed by tightening the threaded abutments 10 at both ends to form the upper fixed end. Then, the electric push cylinder 34 drives the support base 7 to move upward until the guide rod 31 approaches the lower end of the take-up shaft 11. At this time, the free end of the optically transparent adhesive on the take-up shaft 11 is pulled out and guided downward through the hollow part inside the guide rod 31. At this time, the moving rods 33 on both sides are rotated to the outer walls of the optically transparent adhesive on both sides, and the abutment ring 32 contacts the optically transparent adhesive. The two work together to guide the adhesive to extend smoothly downward in the horizontal direction. During the process, the adhesive only contacts the abutment ring 32, and the contact area is small and the surface is smooth to avoid the adhesive sticking to the equipment over a large area. At the same time, the sleeve can slide along the vertical rod 37, driving the moving rod 33 to make slight up and down adjustments to ensure that the adhesive is always laid in a natural state without stretching or folding.

[0049] When the colloid extends above the lower clamping member, the telescopic end of the third hydraulic cylinder 26 above the bracket 25 extends, pushing the movable seat 27 to move towards the fixed seat 24; the abutment blocks 28 on the side of the fixed seat 24 and the movable seat 27 move towards the colloid simultaneously, so that the two sets of abutment blocks 28 clamp the colloid from both sides, firmly fixing the lower end of the colloid between the fixed seat 24 and the movable seat 27, thus completing the bidirectional fixation of the sample.

[0050] Finally, the X-axis drive mechanism 4 and the first hydraulic cylinder 14 realize pressure detection. When the colloid is stretched vertically, the first hydraulic cylinder 14 only needs to extend upward continuously, and the pressure detection sensor 3 performs vertical stretch detection. When different angle stretch tests are required, the rotation mechanism starts to work, the second hydraulic cylinder 21 retracts, and drives the pin 22 to disengage from the gear plate 30; then the motor 8 is started, driving the fixed plate 9 and the upper clamping part to rotate to the required angle (such as 90°, 45°, etc.); then the second hydraulic cylinder 21 extends again, so that the pin 22 is engaged with the gear plate 30 to lock it. The first hydraulic cylinder 14 drives the moving stage 13 and the upper clamping member to move vertically, activating the X-axis drive mechanism 4 on one side of the outer wall of the testing stage 1. The slider 5 drives the upper slide 23 away from the testing frame 2 along the X-axis, thereby causing the lower end of the colloid to move synchronously. The slide 23 drives the lower end of the colloid to move synchronously through the lower clamping member. At the same time, the pressure detection sensor 3 on one side of the testing frame 2 collects the tensile force data of the colloid in real time and transmits the data to the external control system. During the process, when the tensile force reaches the preset value or the colloid deforms or breaks, the X-axis drive mechanism 4 stops. Through the coordinated work of the upper mechanism, the multi-directional complex stresses that optically transparent adhesives bear in practical applications can be simulated, and their mechanical properties can be accurately measured.

[0051] After the test is completed, the electric push cylinder 34 can drive the bidirectional scraper 20 to move down. At the same time, the fixed seat 24 and the movable seat 27 are also adjusted by the third hydraulic cylinder 26 to leave a channel for the bidirectional scraper 20 to pass through the fixed seat 24 and the movable seat 27. Then, the start cylinder 19 drives the slip ring 17 to move slowly along the guide rod 31. The bidirectional scraper 20 moves synchronously with the slip ring 17 and moves between the fixed seat 24 and the movable seat 27 to scrape off any sticky substances that may exist on the surface of the abutment block 28. Then, the bidirectional scraper 20 is reset, and under the drive of the electric push cylinder 34, as the support seat 7 descends, the bidirectional scraper 20 is submerged into the corresponding lower water tank 16 for cleaning, thereby avoiding the difficulty in cleaning itself due to long-term scraping of sticky substances.
