[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0030] It should be noted that the tooling fixture provided by the present invention can be applied to the assembly of display devices, or to other application scenarios in which the function of the tooling fixture can be applied, and the present invention does not limit it in this regard.
[0031] In specific implementation, this invention takes the application of the tooling fixture to the assembly of display devices as an example to illustrate the working principle of the tooling fixture.
[0032] Please see Figure 1 The tooling fixture includes a fixing structure 10, a positioning structure 20, and a pressing structure 30. The fixing structure 10 is used to fix the surface of the workpiece. The positioning structure 20 is connected to the fixing structure 10 and is used to abut against the edge of the workpiece to position the workpiece. The pressing structure 30 is slidably connected to the positioning structure 20 through a connecting component 40 and is used to slide along a direction perpendicular to the surface to press down on a part of the workpiece.
[0033] In this embodiment, the workpiece can be a combination of some structures in a display device. For example, the workpiece may include a liquid crystal glass substrate, a backplate, and COF lines. The liquid crystal glass substrate and the backplate are stacked, and the COF lines are located on the side of the liquid crystal glass substrate. After the liquid crystal glass substrate is installed on the backplate, the COF lines on the side of the liquid crystal glass substrate need to be bent and pressed into the groove of the backplate so that the COF lines can be connected to the circuit board located on the side of the backplate away from the liquid crystal glass substrate. The tooling fixture in this invention can be used to press down the COF lines on the side of the liquid crystal glass substrate. Specifically, the fixing structure 10 can be connected to the surface of the liquid crystal glass substrate to fix the liquid crystal glass substrate. The positioning structure 20 abuts against the edge of the backplate, and then the pressing structure 30 slides relative to the positioning structure 20 in a direction perpendicular to the surface to press down the COF lines on the side of the liquid crystal glass substrate, so that the COF lines are bent and placed in the groove of the backplate. This eliminates the need for manual pressing of the COF lines, thereby improving assembly efficiency.
[0034] The pressing structure 30 is slidably connected to the positioning structure 20 via the connecting component 40. After the fixing structure 10 fixes the workpiece and the positioning structure 20 abuts against the edge of the workpiece, the pressing structure 30 can slide up and down along the direction perpendicular to the surface via the connecting component 40 to press down part of the workpiece.
[0035] In some embodiments, the fixing structure 10 includes a handle 11, and a fixing post 12 is provided on one side of the handle 11. The number of fixing posts 12 can be set according to actual needs; that is, one fixing post 12 or two or more fixing posts 12 can be provided on one side of the handle 11. When one fixing post 12 is provided on one side of the handle 11, one end of the fixing post 12 is fixedly connected to the handle 11, and the other end of the fixing post 12 away from the handle 11 is connected to a suction cup 13. The suction cup 13 adheres to the surface of the liquid crystal glass substrate, connecting with the surface of the liquid crystal glass substrate to fix the liquid crystal glass substrate. Therefore, to ensure the overall balance of the tooling fixture, when one fixing post 12 is provided, it can be positioned in the middle of the handle 11.
[0036] When two or more fixing posts 12 are provided on one side of the handle 11, the multiple fixing posts 12 are spaced apart and located on the same side of the handle 11, forming a comb-like structure together with the handle 11. When two or more fixing posts 12 are provided on one side of the handle 11, at least one of the two or more fixing posts 12 is connected to a suction cup 13. It should be noted that when multiple fixing posts 12 are provided, the fixing posts 12 can be of the same length. In this case, multiple fixing posts 12 can be connected to a suction cup 13 at the same time. In application, multiple suction cups 13 can be selected to simultaneously adhere to the surface of the liquid crystal glass substrate to fix the liquid crystal glass substrate. The simultaneous adhesion of multiple suction cups 13 can improve the stability of the fixation.
[0037] For example, two fixing posts 12 can be provided on one side of the handle 11. In this case, the two fixing posts 12 can be located at both ends of the same side of the handle 11, and suction cups 13 can be provided on both fixing posts 12. Of course, three or four fixing posts 12 can also be provided, etc. The specific setting can be determined according to the application scenario of the tooling fixture. This invention does not make a specific limitation in this regard.
[0038] Of course, if multiple fixing posts 12 located on the same plane are set up, and the lengths of the fixing posts 12 are not the same, it is necessary to ensure that the length of the fixing post 12 connected to the suction cup 13 is greater than that of the fixing post 12 not connected to the suction cup 13, so as to ensure that the suction cup 13 can adhere to the liquid crystal glass substrate of the plane.
[0039] In some embodiments, please refer to the following: Figure 2 The positioning structure 20 includes a positioning plate 21 and a positioning element 22. One side of the positioning plate 21 is connected to the fixing post 12, and the other side of the positioning plate 21 is connected to the positioning element 22. The positioning element 22 is perpendicular to the positioning plate 21, while the positioning plate 21 is parallel to the surface. The positioning element 22 is used to abut against the edge of the workpiece. The positioning element 22 can be integrally formed with the positioning plate 21. The number of positioning elements 22 can be one or more, depending on the specific implementation requirements.
[0040] In one embodiment, a through hole 211 is provided on one side of the positioning plate 21. The positioning plate 21 is sleeved onto the fixing post 12 through the through hole 211, so that the positioning plate 21 is parallel to the surface. The number of through holes 211 on the positioning plate 21 is adapted to the number of fixing posts 12; that is, when there is one fixing post 12, there is one through hole 211; when there are two or more fixing posts 12, there can also be two or more through holes 211. The positioning plate 21 is sleeved onto the fixing post 12 through the through hole 211, so as to fix the positioning plate 21.
[0041] In another embodiment, the shape of the through hole 211 of the positioning plate 21 can be adapted to the shape of the fixing post 12; that is, when the shape of the through hole 211 is polygonal, the fixing post 12 can be a polygonal prism; when the shape of the through hole 211 is circular, the fixing post 12 can be a cylinder. In this embodiment, adapting the shape of the through hole 211 to the shape of the fixing post 12 ensures that the positioning plate 21 can move downward along the fixing post 12, improving the flexibility of the positioning plate 21.
[0042] In another embodiment, a first notch 222 is provided at the end of the positioning member 22 that is away from the positioning plate 21, and the first notch 222 faces the fixed post 12. During positioning, the first notch 222 can abut against the workpiece to improve the positioning accuracy.
[0043] In some embodiments, please refer to the following: Figure 3 The pressing structure 30 includes a pressing plate 31, which is fixedly connected to the connecting assembly 40 in a direction perpendicular to the surface. A protruding pressing member 32 is provided on one side of the pressing plate 31 near the surface, and the pressing member 32 and the pressing plate 31 are located on the same plane. The pressing member 32 and the pressing plate 31 are integrally formed. Since the COF lines on the side of the liquid crystal glass substrate are spaced apart, to adapt to the characteristics of the COF lines on the liquid crystal glass substrate, one or more pressing members 32 are provided on the pressing plate 31. When two or more pressing members 32 are provided, they are spaced apart to allow for the pressing of multiple COF lines at once, thereby improving assembly efficiency.
[0044] As one embodiment, a second notch 321 is provided at the end of the pressing member 32 away from the pressing plate 31, and the second notch 321 faces the fixing post 12. When pressing down the COF line, the second notch 321 is equivalent to a bend, which allows the COF line to make good contact with the liquid crystal glass substrate, thereby effectively bending the COF line, preventing the COF line from popping out, and thus improving the effectiveness of pressing the line.
[0045] As one example, please refer to the following: Figure 4 The distance between the positioning member 22 and the plane where the fixing post 12 is located is greater than the distance between the pressing member 32 and the plane where the fixing post 12 is located. This means that when the COF line is pressed down, the back plate protrudes relative to the liquid crystal glass substrate. The positioning member 22 abuts against the protruding back plate, and then the pressing member 32 presses the COF line of the liquid crystal glass substrate into the groove of the back plate, and abuts against the liquid crystal glass substrate through the COF line.
[0046] In this embodiment, the positioning plate 21 has an extension 23 on the side away from the fixing post 12, with the same number of extensions 23 as the positioning members 22. The extensions 23 are integrally formed with the positioning plate 21, and the pressing member 32 is connected to the positioning plate 21 through a corresponding extension 23. In this embodiment, an extension 23 can be provided at each end of the positioning plate 21 near the positioning plate 21; the two extensions 23 and the positioning plate 21 form a first clearance groove 24. The pressing plate 31 can be based on the first clearance groove 24 to set the pressing member 32. Thus, by setting the first clearance groove 24, the number of pressing members 32 can be increased to match the number of COF lines on the side of the liquid crystal glass substrate.
[0047] As one embodiment, the lower pressure plate 31 is also provided with a second clearance groove 311, which is the same number as the extension 23. The second clearance groove 311 is adapted to the extension 23 to ensure that the lower pressure plate 31 can avoid the extension 23 when it is pressed down, thereby improving the flexibility of the tooling fixture.
[0048] As one embodiment, a bending member 33 is provided on the side of the lower pressure plate 31 opposite to the lower pressure member 32. The bending member 33 is integrally formed with the lower pressure plate 31. The bending member 33 is provided to facilitate the downward pushing of the lower pressure plate 31 relative to the relative sliding of the positioning structure 20.
[0049] In some embodiments, please refer to the following: Figure 4 , Figure 5 and Figure 6 The connecting component 40 includes a slide groove 41 and a slider 42. The slider 42 is partially disposed in the slide groove 41 and slidably connected to the slide groove 41. The slider 42 is also fixedly connected to one side of the positioning plate 21, and the slide groove 41 is also fixedly connected to the lower pressure plate 31.
[0050] Specifically, the slide groove 41 can be directly set at the position of the first clearance groove 24 and fixedly connected to the positioning plate 21. To improve the stability of the fixation, two connecting components 40 can be provided, and the two connecting components 40 can be respectively set at both ends of the first clearance groove 24. At the same time, setting the connecting components 40 at the position of the first clearance groove 24 helps to ensure that the distance between the pressing member 32 and the plane where the fixing post is located is less than the distance between the positioning member 22 and the plane where the fixing post is located.
[0051] In one embodiment, the slide groove 41 has two opposite sidewalls respectively provided with limiting ribs 411, and the slider 42 is provided with a limiting groove 421 adapted to the limiting ribs 411. The limiting ribs 411 are located in the limiting groove 421 to improve the stability of the connection between the slide groove 41 and the slider 42. The cross-section of the limiting groove 421 can be V-shaped, trapezoidal, or semi-circular, etc., and the present invention does not limit it.
[0052] In some embodiments, the connecting assembly 40 further includes a connecting block 43, and the slider 42 in the connecting assembly 40 is fixedly connected to the positioning plate 21 through the connecting block 43; a first connecting post 44 is provided at one end of the connecting block 43 away from the surface; one end of the first connecting post 44 is fixedly connected to the connecting block 43, and the other end of the first connecting post 44 is connected to one end of a spring 45; the lower pressure plate 31 is provided with the same number of second connecting posts 312 as the first connecting posts 44, and the second connecting posts 312 are connected to the other end of the springs 45 connected to the corresponding first connecting posts 44. When the lower pressure plate 31 is pressed down, it can be springed back to its original position by the action of the springs 45, that is, the lower pressure plate 31 can automatically reset after completing the pressing action of the COF line, thereby improving the flexibility of the tooling fixture.
[0053] As another embodiment, the surfaces of the first connecting post 44 and the second connecting post 312 can be roughened; for example, threads can be provided on the surfaces of the first connecting post 44 and the second connecting post 312, thereby preventing the spring 45 from sliding on the first connecting post 44 and the second connecting post 312, which would affect the performance of the spring 45.
[0054] The spring 45 is located on the same plane as the first connecting post 44 and the second connecting post 312, and the plane containing the spring 45 and the first connecting post 44 and the second connecting post 312 is perpendicular to the lower pressure plate 31. This ensures that the spring 45 is aligned with the direction of the lower pressure plate 31's reset, thus ensuring the accuracy and flexibility of the lower pressure plate 31's reset.
[0055] In some embodiments, the handle 11 is also provided with an air valve 14; when the suction cup 13 does not need to be attracted to the liquid crystal glass substrate, the air valve 14 can be pressed to allow air to be filled into the suction cup 13 and detach it from the liquid crystal glass substrate.
[0056] The present invention provides a tooling fixture, comprising a fixing structure 10 for fixing the surface of a workpiece; a positioning structure 20 connected to the fixing structure 10 for abutting against the edge of the workpiece to position the workpiece; and a pressing structure 30 slidably connected to the positioning structure 20 via a connecting component 40 for sliding along a direction perpendicular to the surface to press down on a portion of the workpiece, thereby improving the assembly efficiency of the workpiece.
