Description

Technical Field

[0001] The utility model relates to the technical field of display, in particular to a shading strip attaching tool. Background Art

[0002] With the continuous expansion and upgrading of the display business, the assembly process requirements of display devices (such as TV products) are getting higher and higher. Due to product limitations, during the assembly process of the display module, there will be a certain gap between the display panel (such as a glass panel) and the frame (such as a ground decorative strip) after being bonded, resulting in light leakage. It is usually necessary to stick a high polymer (PET) substrate or a polycarbonate (PC) substrate tape (masking tape) as a shading strip at the corresponding position between the display panel (such as a glass panel) and the frame (such as a ground decorative strip) (i.e., the edge of the display surface of the display panel).

[0003] In the related art, the display module with the display panel attached is manually placed flat, the shading strip is held and the film is torn off to align with a corner of the ground frame, and the shading strip is pasted based on the display panel. Then, a certain amount of additional force is applied to maintain the pressure to ensure that the shading strip is firmly pasted. Since the shading strip is made of soft material, it cannot be guaranteed to be pasted to the corresponding position at one time, and the work efficiency is very low. There are problems such as pasting displacement, excessive gap, and rework and waste of shading strip. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] With the continuous expansion and upgrading of the display business, the assembly process requirements of display devices (such as TV products) are getting higher and higher. Due to product limitations, during the assembly process of the display module, there will be a certain gap between the display panel (such as a glass panel) and the frame (such as a ground decorative strip) after being bonded, resulting in light leakage. It is usually necessary to stick a high polymer (PET) substrate or a polycarbonate (PC) substrate tape (masking tape) as a shading strip at the corresponding position between the display panel (such as a glass panel) and the frame (such as a ground decorative strip) (i.e., the edge of the display surface of the display panel).

[0037] In the related art, the display module with the display panel attached is manually placed flat, the shading strip is held and the film is torn off to align with a corner of the ground frame, and the shading strip is pasted based on the display panel. Then, a certain amount of additional force is applied to maintain the pressure to ensure that the shading strip is firmly pasted. Since the shading strip is made of soft material, it cannot be guaranteed to be pasted to the corresponding position at one time, and the work efficiency is very low. There are problems such as pasting displacement, excessive gap, and rework and waste of shading strip.

[0038] The utility model provides a shading strip attachment tool. Figures 1 to 7 The present invention is an embodiment of a fixture for attaching a shading strip.

[0039] Please see attached Figures 1 to 4 In one embodiment of the utility model, the shading strip attaching jig 100 includes a positioning member 1, two abutting members 2, and a pressing member 3. The positioning member 1 extends along a first direction to have two ends located in the first direction; the two abutting members 2 are correspondingly installed at the two ends of the positioning member 1, and each of the abutting members 2 has an abutting portion 21 that is opposite to the positioning member 1 and spaced apart in the second direction to abut the non-display surface of the display module; the pressing member 3 extends along a third direction and is movably installed along the first direction on one side of the positioning member 1 in the third direction, and the pressing member 3 is on one side of the line connecting the two abutting portions 21; wherein, the pressing member 3 is provided with a limiting portion 31 that is opposite to the positioning member 1 in the third direction at one end away from the positioning member 1, and the limiting portion 31 and the positioning member 1 jointly define a limiting groove.

[0040] The technical solution of the utility model adopts the abutting parts 21 of the two abutting members 2 and the positioning member 1 to be spaced apart in the second direction to clamp the two sides of the display module, and the positioning member 1 is abutted on the display panel, so as to realize the position fixation between the positioning member 1 and the display panel. The positioning member 1 serves as the basic frame of the entire shading strip attaching jig 100, and determines the installation direction of the shading strip 200 by its extension direction. The limiting part 31 of the pressing member 3 and the positioning member 1 form a limiting groove, and the shading strip 200 is placed in the limiting groove. The limiting groove limits the shading strip 200 to ensure that it does not shift during the attachment process and the position is accurate. The pressing member 3 abuts the non-adhesive surface of the shading strip 200 to ensure that the adhesive surface of the shading strip 200 is tightly attached to the display panel. With the movement of the pressing member 3 in the first direction, the shading strip 200 is attached along the first direction to ensure that it is attached in place at one time, thereby improving the attachment accuracy and work efficiency of the shading strip 200.

[0041] In the embodiment of the utility model, the supporting member 2 is a horizontal quick clamp, which is a finished product with low cost, simple structure, and convenient operation, thus reducing cost and further improving work efficiency.

[0042] The present invention does not limit the specific implementation method of the pressing member 3 being movably installed on the positioning member 1 along the first direction. For example, the pressing member 3 is provided on the positioning member 1 via a telescopic rod, and the telescopic rod is telescoped along the first direction to realize the movable installation of the pressing member 3 along the first direction. In the embodiment of the present invention, a slide groove 42 and a slide rail 41 that are slidably matched along the first direction are provided between the pressing member 3 and the positioning member 1. In this way, the pressing member 3 is movably installed on the positioning member 1 along the first direction. The sliding matching method of the slide groove 42 and the slide rail 41 has good motion accuracy, a relatively simple design, and is convenient for daily maintenance and replacement, which is conducive to improving work efficiency and reducing maintenance costs.

[0043] In an embodiment of the utility model, the pressing member 3 includes a roller whose rotating shaft extends along a third direction, and a protrusion is provided on the circumferential side of the roller away from the end of the positioning member 1, and the protrusion extends along the circumference of the roller, and the protrusion forms the limiting portion 31. Compared with the sliding contact, the rolling contact of the roller can significantly reduce the friction force and avoid the wear of the shading strip 200. The roller can adapt to the surface of the shading strip 200 of different materials, provide uniform pressure distribution, and better maintain the continuity and stability of the movement. The protrusion on the circumferential side of the roller serves as the limiting portion 31, which can provide a limiting effect while the roller rolls, ensuring that the position of the shading strip 200 is accurate during the attachment process. This design not only meets the functional requirements, but also maintains the simplicity of the structure, thereby speeding up the attachment process, improving production efficiency, reducing the defective rate in production, and improving product quality.

[0044] In an embodiment of the utility model, the pressing member 3 is elastically installed on the positioning member 1 along the second direction. In this way, during the pasting process, there is no need to manually apply a pressing force. The pressing member 3 can have sufficient pressing force to press the non-adhesive surface of the shading strip 200, which can play a role in maintaining pressure and reduce the risk of debonding, thereby reducing the loss of the shading strip and the fatigue intensity of personnel, improving production efficiency, and ensuring product process consistency.

[0045] The utility model does not impose any specific restrictions on the elastic installation of the pressing member 3. For example, by using the principle of magnetic attraction, a magnet or magnetic material is set between the pressing member 3 and the positioning member 1 to achieve non-contact elastic installation of the pressing member 3 and the positioning member 1, or by applying force through an air pressure or hydraulic system to cause a small displacement between the structures, thereby achieving elastic installation. In the embodiment of the utility model, an elastic member 5 is set between the pressing member 3 and the positioning member 1 (see Figure 6 and Figure 7 ), prestress loading is performed through the elastic member 5 to achieve elastic installation of the pressing member 3. Compared with other complex elastic installation methods, the cost of using the elastic member 5 is low, and the installation and maintenance are relatively simple, which has good cost-effectiveness.

[0046] In the utility model, the elastic member 5 can be a spring, a rubber pad, etc. In the embodiment of the utility model, the elastic member 5 is a spring. The spring has high elasticity and durability, can improve the reliability of the structure, and reduce the product maintenance cost.

[0047] See Figures 5 to 7In an embodiment of the utility model, a mounting portion 11 spaced apart from the pressing member 3 in a first direction is provided on a side of the positioning member 1 opposite to the abutting portion 21, and the mounting portion 11 is provided with a receiving groove 111, and the receiving groove 111 has a first notch 1111 opened on one side of the mounting portion 11 in the first direction; an end of the pressing member 3 close to the positioning member 1 is provided with a connecting portion 32 spaced apart from the positioning member 1 in a second direction, and the connecting portion 32 extends from the end of the pressing member 3 close to the positioning member 1 toward the mounting portion 11, and the free end of the connecting portion 32 extends from the first notch 1111 into the receiving groove 111, and the connecting portion 32 surrounds The shaft along the third direction is rotatably installed on the mounting portion 11, and the shaft of the connecting portion 32 is located between the two groove walls of the accommodating groove 111 in the second direction. The elastic member 5 is arranged between the connecting portion 32 and one of the groove walls. In this way, the connecting portion 32 is formed into a lever, and the two ends of the lever are respectively subjected to the elastic force of the elastic member 5 and the pressing reaction force of the pressing member 3. When the pressing member 3 is lifted by overcoming the force of the elastic member 5, the connecting portion 32 is restricted by one groove wall to avoid excessive movement. When the pressing member 3 is reset under the force of the elastic member 5, the connecting portion 32 is restricted by the other groove wall to avoid excessive pressing force of the pressing member 3, thereby ensuring the stability and safety of the structure during operation.

[0048] In an embodiment of the utility model, the accommodating groove 111 also has a second slot 1112 which is opened on the other side of the mounting portion 11 in the first direction, and the free end of the connecting portion 32 passes through the accommodating groove 111 from the second slot 1112. Through the second slot 1112, bidirectional operation of the connecting portion 32 can be achieved, that is, force can be applied to the connecting portion 32 not only from the first slot 1111 side, but also from the second slot 1112 side, which can increase the operational flexibility and functionality of the structure.

[0049] In the embodiment of the utility model, the spacing between the two abutting members 2 along the first direction can be adjusted, so that the spacing between the two abutting members 2 can be adjusted according to the structural size of the display module of the display device (such as a television) and the position where the abutting members 2 need to be pasted, thereby adjusting the spacing between the two abutting portions 21, that is, one jig can meet the needs of pasting the shading strip 200 on display modules of different sizes, and there is no need to make a tool for each size like a traditional positioning jig, which greatly reduces the time and cost of jig development. Specifically, a long strip hole extending along the first direction is provided on the positioning member 1, and the two abutting members 2 are inserted through the long strip hole at different positions by fasteners to achieve adjustable spacing.

[0050] In the embodiment of the utility model, the material of the positioning member 1 includes aluminum profiles, which are light and high-strength, ensuring the structural quality and reducing the production cost. Specifically, the positioning member 1 is further provided with a reinforcing rib 6 .

[0051] In an embodiment of the utility model, the material of the pressing part 3 includes rubber. The roller made of rubber has good wear resistance, can maintain performance during long-term use, reduce wear and damage, can effectively reduce friction and scratches on the shading strip 200, and protect the shading strip 200 from damage, thereby improving the reliability of the structure, reducing product defective rate, and improving product quality.

[0052] In the embodiment of the utility model, a sponge rubber pad 7 is provided on the side of the positioning member 1 opposite to the abutting portion 21, so that a buffer can be formed between the positioning member 1 and the display surface of the display module to avoid damage to the screen and ensure product quality. The above three embodiments can be selected one by one, two by two, or both.

[0053] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
