[0023] During the manufacturing process of a curved display module, the bare screen needs to be assembled onto the curved backplane for the next assembly production. Since the employees in the bare screen placement position of the module may be affected by other factors in a fixed environment, when assembling the bare screen (OC), there will be a problem of misalignment where the bare screen is not placed in the center, resulting in non-conforming excessive gaps between the bare screen of the whole machine and the rear case, and the problem that the bare screen is easily cracked due to extrusion force when assembling the rear case. This abnormality affects production efficiency and product quality.
[0024] In view of this, an embodiment of the present utility model provides a limiting fixture, which can achieve limiting during the process of assembling the bare screen. When the limiting fixture is placed on both sides of the backplane of the display module, and then the bare screen is placed, effective limiting can be achieved.
[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings.
[0026] Please refer to Figure 1 、 Figure 2 and Figure 4 A limiting fixture proposed by an embodiment of the present utility model is used to assemble a first component 10 and a second component 20. The first component 10 has an adjacent first long side and a first short side, and the second component 20 has an adjacent second long side and a second short side. The second component 20 is provided with a first positioning portion 21. The limiting fixture includes:
[0027] A base 30, the base 30 is provided with a second positioning portion 31, the second positioning portion 31 is used to cooperate with the first positioning portion 21, and the base 30 is used to be attached to the surface of the second component 20 facing away from the first component 10;
[0028] A first stop edge 40, provided on the base 30, used to abut against the first long side and the second long side; and
[0029] A second stop edge 50, provided on the base 30, used to abut against the first short side and the second short side.
[0030] In the technical solution adopted in this embodiment, the base 30 is provided to facilitate the installation of the second component 20 and can provide a supporting effect on the second component 20. Moreover, by using the provided first positioning portion 21 and second positioning portion 31, the base 30 can be conveniently attached to the surface of the second component 20 facing away from the first component 10. It can be understood that when the base 30 is attached to the second component 20, the first edge 40 provided on the base 30 will abut against the second long side, and at the same time, the second edge 50 provided on the base 30 will abut against the second short side. At this time, when the first component 10 is placed, the first long side abuts against the first edge 40 so as to be aligned with the second long side; the first short side abuts against the second baffle so as to be aligned with the second short side. In this embodiment, the first component 10 is a bare display screen, and the second component 20 is a display module, which is set to be curved. The first component 10 can be placed on the curved surface. When the limiting fixture is assembled with the second component 20 and then the first component 10 is placed, the first component 10 can be effectively limited by the first edge 40 and the second edge 50, so as to be aligned and attached to the second component 20. The technical solution proposed in the embodiment of the present utility model enables the on-site employees to standardize their actions in a fixed environment, making them no longer affected by other factors, solves the problem of misalignment of the bare display screen placed by the employees, can effectively improve work efficiency, and improves the quality abnormality and broken screen loss caused by the misalignment of the bare display screen.
[0031] Specifically, the limiting fixture includes a base 30, a first edge 40 and a second edge 50.
[0032] The base 30 can be made of a plastic material with good electrical insulation performance, and its surface is smooth. The corners are set as rounded corners, which has a certain wear resistance and can provide a supporting effect.
[0033] The first edge 40 is bent and connected to one side edge of the base 30 facing the second component 20 along the length direction. The alignment of the first long side and the second long side can be achieved by abutting the first edge 40 against the first long side and the second long side.
[0034] The second edge 50 is bent and connected to one side edge of the base 30 facing the second component 20 along the width direction. The alignment of the first short side and the second short side can be achieved by abutting the second edge 50 against the first short side and the second short side. It can be understood that when the first edge 40 abuts against the second long side, the second edge 50 abuts against the second short side. In this way, when the first component 10 is placed, the first long side can be aligned with the second long side, and the first short side can be aligned with the second short side, so as to effectively limit the first component 10.
[0035] Further, referring to Figure 4, in an embodiment of the present utility model, one of the first positioning portion 21 and the second positioning portion 31 is a positioning protrusion, and the other is a positioning groove.
[0036] In the technical solution adopted in this embodiment, the positioning protrusion is provided at the end of the second member 20 on the side facing away from the first member 10, and the positioning groove is provided on the surface of the base 30 facing the abutting surface of the second member 20. Therefore, when the base 30 is attached to the second member 20, the positioning protrusion cooperates with the positioning groove so that the base 30 and the second member 20 are relatively fixed. The positioning cooperation is realized in the form of a positioning protrusion and a positioning groove, which is relatively simple in structure and has good stability of the positioning cooperation. It can be understood that the positioning groove can completely cover the positioning protrusion, so that the base 30 can be closely attached to the second member 20.
[0037] Further, referring to Figure 2 、 Figure 4 , in an embodiment of the present utility model, the first retaining edge 40 and the base 30 are integrally formed; or,
[0038] The second retaining edge 50 and the base 30 are integrally formed.
[0039] In the technical solution adopted in this embodiment, the first retaining edge 40 and the base 30 are provided integrally formed, or the second retaining edge 50 and the base 30 are provided integrally formed. By setting like this, the number of components can be reduced, the overall design can be simplified, and the design complexity can be reduced. At the same time, the connection points between components are reduced, thereby reducing potential failure points and improving the reliability of the product. Moreover, the integral structure is usually more robust and can provide better stability and durability.
[0040] Further, referring to Figure 5 、 Figure 6 , in an embodiment of the present utility model, the side surface of the first retaining edge 40 facing the first long side is provided with a first protrusion 41; or,
[0041] The side surface of the second retaining edge 50 close to the second short side has a second protrusion 51.
[0042] In the technical solution adopted in this embodiment, by providing the first protrusion 41, the gap between the first retaining edge 40 and the second long side can be reduced; at the same time, by providing the second protrusion 51, the gap between the second retaining edge 50 and the second short side can be reduced, so that the possibility of the first member 10 being offset and not centered can be further reduced, and the reliability of the limiting jig can be improved. In this embodiment, the width of the first protrusion 41 can be 0.85 mm, or 0.65 mm, or 0.45 mm. Correspondingly, the width of the second protrusion 51 can be 0.7 mm, or 0.5 mm, or 0.3 mm.
[0043] Further, referring to Figure 3 and Figure 4 , in an embodiment of the present utility model, the surface of the base 30 facing the abutment of the second member 20 is adapted to the shape of the surface of the second member 20 facing the base 30.
[0044] In the technical solution adopted in this embodiment, by setting the surface of the base 30 facing the abutment of the second member 20 to be adapted to the shape of the surface of the second member 20 facing the base 30, it is possible to ensure the precise fit between the base 30 and the second member 20 and provide accurate positioning. It can be understood that the adapted surface can provide better mechanical locking and enhance the stability of the assembly of the second member 20 and the base 30. That is to say, the shape adaptation can help to limit the unnecessary movement or sliding of the base 30, reduce the possibility of misalignment between the base 30 and the second member 20, and improve the performance and quality of the product.
[0045] Further, referring to Figure 2 , in an embodiment of the present utility model, the positioning fixture further includes a magnetic attraction structure 60 provided on the base 30 for attracting the second member 20.
[0046] In the technical solution adopted in this embodiment, the positioning fixture may further include a magnetic attraction structure 60. The magnetic attraction structure 60 is fixedly connected to the base 30 to fix the base 30 on the second member 20 through the attraction force of the magnetic attraction structure 60. It can be understood that a magnetic attraction structure 60 with an attraction force is provided on the base 30. Through the attraction force of the magnetic attraction structure 60, the base 30 and the second member 20 can be connected to achieve quick disassembly and assembly. In this embodiment, the magnetic attraction structure 60 may be a magnetic strip. The magnetic strip may be provided between the base 30 and the second member 20. When the base 30 and the second member 20 are in contact, the magnetic strip fixes the base 30 and the second member 20 together under the action of the attraction force. The magnetic attraction structure 60 may be provided with one or multiple, which is not limited herein.
[0047] Further, referring to Figure 2 , in an embodiment of the present utility model, the base 30 is provided with mounting holes, and the magnetic attraction structure 60 includes magnets. The magnets are provided inside the mounting holes, and multiple magnets are arranged in an array on the base 30.
[0048] In the technical solution adopted in this embodiment, the magnetic attraction structure 60 further includes a magnet, and the magnet is fixed in the mounting hole of the base 30 by glue. It can be understood that when installing the magnet, the side of the magnet located outside the mounting hole and the side of the base 30 facing the second member 20 are on the same horizontal plane, so that when the base 30 is attached to the surface of the second member 20, the magnet and the second member 20 are magnetically attracted to fix the base 30 and the second member 20 to provide more stable support. Specifically, when the base 30 needs to be installed, the side of the base 30 with the magnet adsorption end is close to the surface of the second member 20 facing away from the first member 10, and the magnet can be adsorbed on the second member 20, thereby realizing the fixation of the base 30. In addition, when disassembling the base 30, applying a force to the base 30 can complete the separation of the magnet from the second member 20, that is, the separation of the base 30 from the second member 20, and the operation is simple and convenient.
[0049] Further, referring to Figure 2 , in an embodiment of the present invention, two second positioning portions 31 are provided at intervals along the length direction of the base 30, each second positioning portion 31 is correspondingly provided with a first positioning portion 21, at least one magnet is provided between the two second positioning portions 31, and at least one magnet is provided between the second baffle 50 and a second positioning portion 31 close to the second baffle 50.
[0050] In the technical solution adopted in this embodiment, two second positioning portions 31 are provided at intervals along the length direction of the base 30, which can ensure that the base 30 and the second member 20 are fixed in the correct position and direction, and can provide more accurate positioning, reduce the assembly error, and the clear positioning points can simplify the assembly process and reduce the assembly time. The two positioning portions cooperate with each other to provide better stability and prevent the base 30 from shifting after being stressed. Specifically, at least one magnet is provided between the two second positioning portions 31, that is to say, when the two second positioning portions 31 are respectively attached to the two first positioning portions 21, the part of the base 30 between the two second positioning portions 31 can be adsorbed on the second member 20 by the magnet, which can strengthen the connection between the part of the base 30 between the two second positioning portions 31 and the second member 20. In addition, at least one magnet is provided between the second baffle 50 and a second positioning portion 31 close to the second baffle 50, which can strengthen the connection between the part of the base 30 between the second baffle 50 and a second positioning portion 31 close to the second baffle 50 and the second member 20. It can be understood that by setting like this, the magnet can be effectively used to achieve the relatively best assembly effect in a limited space.
[0051] Further, referring to Figure 5 , in an embodiment of the present invention, the limiting component further includes an extension portion 70, and the extension portion 70 is provided at the bottom of a positioning portion away from the second baffle 50.
[0052] In the technical solution adopted in this embodiment, by providing the extension portion 70, the limiting fixture can have the function of preventing misalignment in the left and right directions, ensuring that the base 30 can only be assembled on the second component 20 in the correct position and direction, thereby avoiding errors in the left and right directions.
[0053] Further, referring to Figure 2 , in an embodiment of the present invention, two magnets are provided at intervals along the width direction of the base 30, and the two magnets are provided on opposite sides of a second positioning portion 31 away from the second edge 50.
[0054] In the technical solution adopted in this embodiment, by providing two magnets at intervals along the width direction of the base 30, the connection between the base 30 and the second component 20 can be strengthened, the stability can be improved, and the possibility of the base 30 warping due to external factors can be reduced. Moreover, the two magnets are provided on opposite sides of a second positioning portion 31 away from the second edge 50, making the connection between the second positioning portion 31 and the first positioning portion 21 more firm. In this way, through the setting of the magnet positions, the connection between the base 30 and the second component 20 can be made more reliable, thereby better meeting the requirements of the staff for the precise assembly of the first component 10.
[0055] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
