[0032] To solve this technical problem, this utility model provides a pasting tooling for a display module.

[0033] Specifically, please refer to Figures 1 - 4 , the display module specifically includes:

[0034] A positioning frame 3, in which a first positioning groove 301 and a second positioning groove 302 are provided, and the first positioning groove 301 and the second positioning groove 302 cooperate for positioning during the pasting of the display module.

[0035] The pasting tooling for the display module provided by the utility model can, through the design of the tooling, accurately position key components such as the touch control module, frame glue, and backlight during the pasting process, effectively avoiding the misalignment problems that occur during manual pasting, reducing rework and correction caused by misalignment, thereby improving the overall production efficiency.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, without conflict, the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0039] Embodiment 1 of the pasting tooling for the display module of the utility model

[0040] Please refer to Figures 1 - 4 , the pasting tooling for the display module provided by the utility model includes a positioning frame 3. A first positioning groove 301 and a second positioning groove 302 are arranged in the positioning frame 3. The first positioning groove 301 and the second positioning groove 302 cooperate for positioning during the pasting of the display module.

[0041] Through the design of the tooling, the utility model can accurately position key components such as the touch control module, frame glue, and backlight during the pasting process, effectively avoiding the misalignment problems that occur during manual pasting, reducing rework and correction caused by misalignment, thereby improving the overall production efficiency. The accurate pasting ensures the structural integrity and functionality of the display screen module, enhancing the overall quality of the product and user satisfaction;

[0042] Through reducing the defective product rate and improving production, the carefully designed positioning grooves can provide precise and stable position guidance for each component of the display module during pasting. This not only eliminates the common position deviation problems in manual operations but also ensures the consistency and accuracy of each pasting operation. The precise positioning greatly reduces the generation of defective products caused by inaccurate positions, thus effectively saving raw material costs. In addition, since the need for errors and adjustments is reduced, the entire production process becomes smoother, significantly improving production efficiency. In the long run, it helps to reduce production costs.

[0043] Furthermore, the first positioning groove 301 is used for the positioning of the backlight rubber frame, and the second positioning groove 302 is used for the positioning of the touch control module. The backlight rubber frame and the touch control module are positioned respectively, so that these two key components can be perfectly fitted when pasted. Precise fitting helps to improve the sealing performance and optical performance of the display module, reduce light leakage and refraction, and thus enhance the clarity and brightness uniformity of the display effect. By positioning the backlight rubber frame and the touch control module separately and precisely, the good sealing performance effectively prevents the intrusion of external impurities such as dust and water vapor, extends the service life of the product. At the same time, precise fitting significantly reduces the light leakage and refraction phenomenon, which enables the light to pass through the display module more concentratedly and uniformly, thereby greatly enhancing the clarity and brightness uniformity of the display effect. When users watch, they can enjoy clearer, brighter and more colorful images, enhancing the market competitiveness of the product.

[0044] Furthermore, limiting members are arranged on both side walls of the second positioning groove 302. The limiting members are used for the positioning of the frame glue, which helps to ensure that the frame glue is accurately positioned and evenly distributed when pasted, thus ensuring the pasting quality and effect, and improving its impact resistance and vibration resistance. The limiting members arranged on both side walls of the second positioning groove 302 play a crucial role in the positioning of the frame glue. By ensuring that the frame glue is accurately positioned and evenly distributed when pasted, the pasting quality and effect can be significantly improved. The accurate position of the frame glue makes the connection between components more tight and stable, thus greatly enhancing the overall structural strength of the product. When facing external impacts and vibrations, this stable structure can effectively absorb and disperse energy, reduce damage to internal components, and significantly improve the impact resistance and vibration resistance of the product. This not only extends the service life of the product, but also reduces the cost and frequency of after-sales maintenance.

[0045] Furthermore, as Figure 1 and Figure 2 shown, the limiting member includes a connecting rod 303 inserted and connected with the positioning frame 3. One end of the connecting rod 303 extends into the second positioning groove 302 and is fixedly connected with a positioning strip 304. The positioning strip 304 is used for limiting the frame glue, so that the position of the frame glue is more accurate when pasted to the backlight rubber frame. This unique design of the limiting member, especially the combination of the connecting rod 303 and the positioning strip 304, provides extremely high precision and reliability for the positioning of the frame glue. The inserted and connected manner of the connecting rod 303 ensures the stable position of the positioning strip 304 and is not easy to shift, thus providing a continuous and accurate limiting effect for the frame glue. When the frame glue is pasted to the backlight rubber frame, the positioning strip 304 can ensure its position is accurate without error, thus further improving the assembly quality of the product. This high-precision positioning helps to reduce the accumulation of tiny errors and ensures the consistency and stability of the product in large-scale production.

[0046] Furthermore, as Figure 1and Figure 2 As shown in Figure 2 , the other end of the connecting rod 303 passes through the positioning frame 3, and a pull handle 305 is fixedly connected to the other end of the connecting rod 303. By pulling the pull handle 305, the connecting rod 303 can drive the positioning strip 304 away from the frame adhesive, avoiding the removal of the positioning strip 304 from the backlight adhesive frame after pasting. The design of the pull handle 305 brings great convenience and flexibility to the production operation. By simply pulling the pull handle 305, the movement of the connecting rod 303 and the positioning strip 304 can be easily controlled to move them away from the frame adhesive. This operation is not only simple and fast, but also avoids the obstruction caused by the positioning strip 304 to the removal of the backlight adhesive frame after pasting. This convenient design greatly shortens the operation time and improves the production efficiency. At the same time, since the backlight adhesive frame can be smoothly removed, the risk of product damage caused by forced removal is reduced, further ensuring the quality and integrity of the product.

[0047] Furthermore, as Figure 1 and Figure 2 shown, a side groove 306 is formed on the side wall of the second positioning groove 302, and the side groove 306 is used to accommodate the positioning strip 304. When the positioning strip 304 is not needed, the side groove 306 provides a dedicated accommodation space for it. This not only effectively utilizes the space, reduces unnecessary protruding parts, but also avoids the interference and collision that the positioning strip 304 may cause in the non-working state. At the same time, the existence of the side groove 306 helps to maintain the flatness of the tooling surface, facilitates operation and cleaning, and further improves the efficiency and safety of the production process.

[0048] Embodiment Two of the Pasting Tooling for the Display Module of the Present Utility Model

[0049] Furthermore, as for the pasting tooling for the display module of the present utility model, as Figure 1 and Figure 4 shown, a support box 4 is slidably connected to the outside of the bottom of the positioning frame 3, and the support box 4 is used for supporting the positioning frame 3.

[0050] Furthermore, as Figure 1 and Figure 3 shown, a second wedge block 6 is fixedly installed in the support box 4, the second wedge block 6 is slidably connected with a first wedge block 5, the top end of the first wedge block 5 passes through the positioning frame 3, and the positioning frame 3 can drive the first wedge block 5 to rise under the limit of the second wedge block 6 during the moving process. The backlight adhesive frame can be jacked up by the first wedge block 5, and thus it is convenient to take out the backlight adhesive frame.

[0051] Embodiment Three of the Pasting Tooling for the Display Module of the Present Utility Model

[0052] Furthermore, positioning members are arranged between the two sides of the first wedge block 5 and the positioning frame 3, and the positioning members are used for positioning the first wedge block 5.

[0053] Furthermore, as Figure 3 shown, the positioning member includes a receiving groove 501 formed on the side surface of the first wedge block 5. A guide rail 502 is fixedly installed in the receiving groove 501. A sliding seat 503 is slidably connected to the outer surface of the guide rail 502. The sliding seat 503 is fixedly connected to the positioning frame 3. The sliding seat 503 and the guide rail 502 cooperate to limit the first wedge block 5, making the lifting process of the first wedge block 5 more stable. The cooperation structure of the sliding seat 503 and the guide rail 502 brings excellent stability and smoothness to the lifting process of the first wedge block 5. The guide rail 502 is fixed in the receiving groove 501, providing an accurate path for the movement of the sliding seat 503, ensuring that the first wedge block 5 will not deviate or get stuck during lifting. The fixed connection between the sliding seat 503 and the positioning frame 3 further enhances the stability of the entire system. This stable and smooth lifting action not only improves the working efficiency of the tooling, but also reduces the noise and vibration generated by unstable movement, improving the working environment.

[0054] As Figure 5 shown, the display module includes: a backlight rubber frame main body 1. A widened skirt 101 is provided on the outer peripheral side of the backlight rubber frame main body 1. A frame adhesive main body 103 is pasted on the widened skirt 101, and the frame adhesive main body 103 is connected to a touch control module main body 105. A liquid crystal display panel 2 is provided between the frame adhesive main body 103 and the backlight rubber frame main body 1;

[0055] The touch control module main body 105 includes a sensor bonded to the frame adhesive main body 103. A cover plate is connected to the side of the sensor away from the frame adhesive main body 103. This clearly layered connection structure enables each component of the touch control module to perform its own functions;

[0056] A chamfer 102 is provided at the connection between the bottom of the widened skirt 101 and the backlight rubber frame main body 1. The chamfer 102 can support the widened skirt 101 to improve the stability of the widened skirt 101. The chamfer 102 provides additional support for the widened skirt 101. From a mechanical point of view, the chamfer 102 can disperse stress, making the widened skirt 101 not easily deformed or broken when bearing external forces. This not only enhances the stability of the widened skirt 101 itself, but also further ensures the firmness of the bonding of the frame adhesive main body 103. In practical applications, for example, when the device is accidentally squeezed or the material expands and contracts due to temperature changes, the chamfer 102 can effectively relieve the influence of these factors on the widened skirt 101 and the frame adhesive main body 103, thus maintaining the normal working state of the display module.

[0057] During use, referring to Figure 4 and Figure 5, for the convenience of understanding, the backlight rubber frame in the above text is the backlight rubber frame main body 1, the frame glue is the frame glue main body 103, and the touch control module is the touch control module main body 105. First, place the backlight rubber frame main body 1 in the first positioning groove 301, then set the frame glue main body 103 on the backlight rubber frame main body 1, and then place the touch control module main body 105 in the second positioning groove 302 so that the touch control module main body 105 is pasted together with the frame glue main body 103. After the pasting is completed, pull the pull handle 305 to make the positioning strip 304 away from the frame glue main body 103, and push the positioning frame 3 to move. During the movement of the positioning frame 3, it is limited by the second wedge block 6 and can drive the first wedge block 5 to rise. Through the first wedge block 5, the backlight rubber frame main body 1 can be jacked up, and then it is convenient to take out the backlight rubber frame main body 1.
