Description

Technical Field

[0001] The present invention relates to the technical field of release film detection, and particularly to a tensile detection device for the production of release films. Background Art

[0002] During the production process of release films, the tensile strength is one of the key indicators to measure the product quality, directly affecting the reliability of release films in subsequent processing and application scenarios. With the continuous improvement of the performance requirements for release films in industries such as electronics and optics, accurately detecting the tensile strength of release films has become an important link in the production process.

[0003] Existing release film tensile detection devices have obvious deficiencies in practical applications. On the one hand, the clamping structure design of traditional detection devices is relatively simple, mostly using rigid clamping methods, which are difficult to adapt to release films of different thicknesses or materials, and it is easy to occur situations where the clamping is not firm or the release film is damaged due to excessive extrusion, thereby affecting the authenticity of the detection results. On the other hand, the stretching mechanism of existing devices lacks flexibility, unable to freely switch between single-direction or double-direction stretching modes according to detection requirements, with limited application ranges, and there is a lack of effective protection for the stress points of the release film during the detection process, which may lead to deviation of detection data due to friction or stress concentration, reducing the detection efficiency and the practicality of the device.

Detailed implementation manners

[0024] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0025] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.

[0028] Embodiment 1 Referring to Figures 1 to 6 , which is the first embodiment of the present invention. This embodiment provides a tensile testing device for the production of release films, which can achieve stable clamping at the installation position of the release film, avoiding inaccurate test results caused by unstable installation of the release film. Therefore, the accuracy of the tensile test of the release film is greatly improved, and the work efficiency is increased.

[0029] Specifically, it includes a base body 1, a first rotating assembly 2 rotatably connected to the base body 1, a second rotating assembly 3 rotatably connected to one side of the first rotating assembly 2, and two sets of mounting assemblies 4 movably connected to the first rotating assembly 2 and the second rotating assembly 3, respectively. The mounting assembly includes a shell 41, an anti-slip portion 42 slidably connected to the inside of the shell 41, a pressing portion 43 movably connected to the upper end of the shell 41, a containing portion 44 rotatably connected to the upper end of the shell 41, and a lifting portion 45 slidably connected to the shell 41.

[0030] When in use, first lift the pressing part 43 upwards, and when the pressing part 43 is fully extended out of the shell 41, place the release film on the containing part 44, and move one end of the release film to the bottom of the pressing part 43; secondly, push the pressing part 43 downwards, and when the pressing part 43 contacts the release film, rotate the pressing part 43 180 degrees so that the pressing part 43 is located inside the shell 41 and presses the anti-slip part 42 under the action of elastic force, and the anti-slip part 42 moves upward inside the shell 41 until it supports the lower end of the release film, thereby completing the clamping; during the rotation of the pressing part 43, it can also drive the lifting part 45 to move left and right, and when the lifting part 45 moves left and right, it drives the containing part 44 to rotate, thereby realizing the retraction of the containing part 44 and the protection of the force-bearing position of the release film.

[0031] Furthermore, the shell 41 includes a moving seat 411, a accommodating cavity 412 opened inside the moving seat 411, a accommodating frame 413 opened at the upper end of the moving seat 411, two groups of support blocks 414 fixedly arranged at both ends of the moving seat 411, sliding grooves 415 fixedly arranged at both ends of the moving seat 411, and an arc groove 416 fixedly arranged at the upper end of the moving seat 411.

[0032] Furthermore, the anti-slip portion 42 includes an anti-slip sheet 421 disposed on the accommodating cavity 412, a lower end connecting block 422 fixedly disposed on the anti-slip sheet 421, and four groups of limiting columns 423 symmetrically disposed on both sides of the connecting block 422, and each group of limiting columns 423 is provided with a first spring 424; One end of the first spring 424 away from the limiting column 423 is fixedly connected to the inner wall of the accommodating cavity 412 ; the upper end of the accommodating cavity 412 extends to the bottom of the arc-shaped groove 416 .

[0033] Furthermore, the pressing part 43 includes a rotating roller 431 matched with the arc groove 416, two sets of moving blocks 432 arranged on both sides of the rotating roller 431, a gear 433 arranged on the moving block 432, a connecting rod 434 arranged on the gear 433, a second spring 435 arranged inside the connecting rod 434, and a rotating rod 436 arranged on the second spring 435; The rotating rod 436 is inserted into the connecting rod 434 , and an annular groove 4141 is provided inside the supporting block 414 to facilitate the upward and downward movement of the moving block 432 .

[0034] It should be noted that the clamping method of the rotating roller 431 and the arc groove 416 can achieve large-area friction clamping of the release film and is not easy to slip. When the release film is clamped, the rotating rod 436 is first rotated 180° and then loosened. The rotating rod 436 is retracted to the inside of the connecting rod 434 and the accommodating cavity 412 under the elastic force of the second spring 435 to complete the undercut locking of the pressing part 43. This undercut locking method can prevent the pressing part 43 from loosening and rotating during the tensile test of the release film.

[0035] Preferably, in the process of the pressing portion 43 completing the buckle locking, the anti-slip portion 42 is also moved upward. When the rotating rod 436 moves to the inside of the accommodating cavity 412 under the elastic force of the second spring 435, it drives the connecting block 422 to move upward. At this time, the anti-slip sheet 421 moves upward and supports the lower end of the release film, thereby further clamping the lower end of the release film. The top of the anti-slip sheet 421 is made of a rubber material and has a good anti-slip effect.

[0036] Furthermore, the containing portion 44 includes a rotating shaft 441 rotatably connected to the inner side of the movable seat 411, a containing plate 442 fixedly disposed on the rotating shaft 441, two sets of rotating wheels 443 fixedly disposed at the lower end of the containing plate 442, and a cam 444 connected to the containing plate 442 at a position close to the arc groove 416.

[0037] Furthermore, the lifting part 45 includes a third spring 451 fixedly connected to the moving seat 411, a tooth block 452 arranged on the third spring 451, a connecting strip 453 arranged at one end of the tooth block 452, and a wedge block 454 arranged on the connecting strip 453; the wedge block 454 is arranged in the receiving frame 413, and the third spring 451, the connecting strip 453 and the tooth block 452 are all provided in two groups; The gear 433 and the gear block 452 are meshed with each other.

[0038] It should be noted that when the pressing part 43 rotates, it can also drive the lifting part 45 to move. During the rotation of the rotating rod 436, the gear 433 is driven to rotate. The rotation of the gear 433 drives the tooth block 452 to move at both ends of the moving seat 411. Both ends of the connecting bar 453 are respectively connected to the tooth block 452 and the wedge block 454. Therefore, the wedge block 454 can be driven to move within the receiving frame 413 under the drive of the gear 433. When the lifting part 45 moves, it can drive the placing part 44 to perform a rotational motion; one side of the wedge block 454 is set as an arc surface, and the rotating wheel 443 is in contact with the arc surface. When the wedge block 454 moves away from the gear 433, the rotating wheel 443 gradually moves from the high point of the arc surface to the low point of the arc surface along the arc surface trajectory. At this time, the placing plate 442 rotates around the rotating shaft 441. When the pressing part 43 achieves reverse buckling and locking, the rotating wheel 443 moves to the lowest point of the arc surface of the wedge block 454. At this time, the placing plate 442 retracts into the receiving frame 413; the cam 444 also rotates under the drive of the rotating shaft 441. When the rotating wheel 443 moves to the lowest point of the arc surface of the wedge block 454, the outer wall of the cam 444 fits with the arc-shaped groove 416.

[0039] It should also be noted that the placing part 44 is mainly used to provide a stable placing plane for the release film. When both ends of the release film are stably placed on the placing plate 442, the rotating roller 431 can be more closely pressed against the release film. When the pressing part 43 achieves reverse buckling and locking, the design that the outer wall of the cam 444 fits with the arc-shaped groove 416 can reduce the friction at the force application points of the release film during the tensile test of the release film, thereby improving the service life of the device.

[0040] Preferably, when the detection is completed, only the rotating rod 436 needs to be rotated so that it withdraws from the receiving cavity 412. The design of the first spring 424 provides a more labor-saving operation for the withdrawal of the rotating rod 436. Therefore, the device has good convenience when disassembling the release film.

[0041] In summary, through the multiple linkage structures of the anti-slip part, the pressing part, the placing part, and the lifting part in the installation component, and by using the elastic pressing and curved surface clamping methods, it can adapt to release films of different thicknesses and achieve non-damaging and stable clamping, effectively avoiding displacement or inaccurate results caused by unstable installation during the detection, and greatly improving the detection accuracy.

[0042] Embodiment 2 Referring to Figure 1 and Figure 7 , for the second embodiment of the present invention, the tensile test device for release film production can achieve free switching between unidirectional pulling and bidirectional pulling, and is applicable to release films of various models.

[0043] Specifically, it includes that the first rotating assembly 2 includes a first lead screw 21 rotatably connected to the base 1, a threaded shaft 22 screwed inside the first lead screw 21, and a threaded sleeve 23 provided on the threaded shaft 22.

[0044] Furthermore, the second rotating assembly 3 includes a connecting sleeve 31 that cooperates with the threaded shaft 22, and a second lead screw 32 provided on the connecting sleeve 31; one end of the second lead screw 32 away from the connecting sleeve 31 is rotatably connected to the base 1.

[0045] Preferably, the inside of the connecting sleeve 31 is provided with a thread that cooperates with the threaded shaft 22.

[0046] Furthermore, one end of the base 1 close to the threaded sleeve 23 is provided with a threaded hole 11 that cooperates with the threaded sleeve 23, and the base 1 is provided with a limiting groove 12 for facilitating the movement of the moving base 411.

[0047] Furthermore, the base 1 further includes four groups of foot posts 13, and a motor 14 connected to the second lead screw 32.

[0048] During use, by rotating the threaded sleeve 23, the threaded shaft 22 rotates inside the first lead screw 21 until it extends out of one end of the first lead screw 21 close to the connecting sleeve 31. At this time, rotating the threaded sleeve 23 again connects the threaded shaft 22 and the connecting sleeve 23, realizing the connection between the first lead screw 21 and the second lead screw 32. The threads of the first lead screw 21 and the second lead screw 32 are opposite. Therefore, when the motor 14 is started, the two mounting assemblies 4 move in opposite directions, thereby realizing the double-direction tensile test of the release film of the device. Rotating the threaded sleeve 23 again to connect it with the threaded hole 11. At this time, the threaded shaft 22 respectively rotates out of the threads inside the first lead screw 21 and the connecting sleeve 23, and the three are no longer connected. In this state, the mounting assembly 4 on the first lead screw 21 stops working, and the mounting assembly 4 on the second lead screw 32 moves, thereby realizing the single-direction tensile test of the release film of the device.

[0049] In summary, through the structural design of setting the threaded shaft to rotate with the first lead screw and the second lead screw, the present invention can realize the free switching between single-direction pulling and double-direction pulling, and is applicable to release films of various models; at the same time, the design of the threaded sleeve makes the device more convenient when switching the pulling method freely.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
