Description

Technical Field

[0001] This utility model relates to the field of auxiliary fixture technology, and in particular to a reflective side-attachment auxiliary fixture. Background Technology

[0002] In liquid crystal display technology, the light guide plate is an indispensable and important component of the LCD screen. The LCD screen itself cannot emit light; its display principle relies on the light provided by the backlight. The main function of the light guide plate is to guide the light emitted by the backlight evenly to the entire LCD panel, thereby providing uniform brightness to the screen and ensuring that the image is clear, bright, and without dark areas. However, in the production process of the light guide plate, in order to further optimize its optical performance and improve the display effect, it is necessary to attach a reflective sideplate to its edge. The function of the reflective sideplate is to prevent light from leaking from the edge of the light guide plate, thereby improving the light utilization rate, enhancing the display brightness, and helping to improve the optical uniformity of the screen, making the brightness of the entire screen more consistent and improving the visual effect.

[0003] However, when attaching the reflective sideplate to the light guide plate, manual alignment is required to attach it to the edge of the light guide plate. This manual alignment method is inefficient and cannot meet the needs of large-scale production. Secondly, during the attachment process, due to human interference, the reflective sideplate is prone to bending and deformation. This bending not only affects the optical performance of the reflective sideplate and reduces its reflection effect, but may also cause light leakage at the edge of the light guide plate, thereby affecting the display quality of the entire LCD screen.

[0004] To address the aforementioned issues, this application proposes a reflective side-attachment auxiliary fixture. Utility Model Content

[0005] This invention proposes an auxiliary fixture for attaching reflective side-mounted adhesive, which solves the problems in related technologies where manual attachment of reflective side-mounted adhesive in light guide plate production results in low alignment efficiency, difficulty in meeting the needs of large-scale production, and easy bending and deformation during the attachment process, leading to decreased optical performance, light leakage, and impact on display quality.

[0006] This utility model proposes a reflective side-mounting auxiliary fixture, which includes a support and a fixture component;

[0007] The fixture is mounted on the support and is used to connect to the negative pressure pump to generate suction. Multiple reflective stickers can be simultaneously adsorbed on the fixture for attaching the light guide plate.

[0008] As a further optimization of this utility model, the fixture includes a fixture plate, which is mounted on a support. A cavity is formed inside the fixture plate. Multiple spaced limiting grooves are formed on the top surface of the fixture plate along its length for placing reflective stickers. The limiting grooves are connected to the cavity. The fixture plate is used to connect to a negative pressure pump, which generates a suction force in the limiting grooves through the cavity to adsorb the reflective stickers.

[0009] As a further optimization of this utility model, the bottom wall of the limiting groove is provided with a plurality of spaced adsorption holes along its length, and under the action of the negative pressure pump, a suction force is formed in the adsorption holes.

[0010] As a further optimization of this utility model, an air inlet is provided on the edge of the top surface of the support, and the air inlet is used to connect to the pipe on the vacuum pump.

[0011] As a further optimization of this utility model, the support is provided with legs on all four sides of its bottom, and the legs are cylindrical to form a support structure for the support.

[0012] As a further optimization of this utility model, a rubber pad is integrally connected to the bottom surface of the support leg.

[0013] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] 1. In use, the reflective sticker adapted to the light guide plate is placed in the limiting groove opened on the fixture plate. Since there are multiple limiting grooves, multiple reflective stickers can be placed at the same time. Then, the air inlet on the fixture plate is connected to the negative pressure pipe of the negative pressure pump. The negative pressure pump is started, generating negative pressure in the cavity inside the fixture plate, and generating suction force in the adsorption hole in the limiting groove, which can adsorb the reflective sticker. Then, the light guide plate is placed vertically, and the edge to be attached is inserted into the corresponding limiting groove so that it is attached to the adhesive surface of the reflective sticker. When assembling the reflective sticker, only the top surface and the two sides of the light guide plate need to be attached. The subsequent adhesion process can be completed according to the above scheme. The above design can perform reflective sticker attachment operations on multiple light guide plates at the same time without manual alignment, saving time and labor costs. It is suitable for large-scale production tasks. In addition, the reflective sticker is fixed by negative pressure adsorption, which can ensure that the reflective sticker remains flat during the attachment process and avoid deformation problems caused by human factors.

[0015] 2. The limiting groove on the fixture plate of this utility model is opened along its length, so it can be adapted to the placement of reflective stickers of different lengths. There is no need to frequently change the fixture plate or adjust the equipment for light guide plates of different lengths, which enhances the versatility of the equipment, reduces the investment cost of the equipment, and improves the utilization rate of the equipment. In addition, the design of the limiting groove not only facilitates the placement of reflective stickers, but also makes the entire application process simpler and clearer, making it easier for operators to get started and reducing the skill level requirements for operators. At the same time, this structural design also facilitates the maintenance and cleaning of the equipment. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 1-6 As shown, the present invention proposes a reflective side-mounting auxiliary fixture, which includes a support 1 and a fixture component 2.

[0025] The fixture 2 is mounted on the support 1 and is used to connect to the negative pressure pump to generate suction force. Multiple reflective stickers can be simultaneously adsorbed on the fixture 2 for the application of the light guide plate. When the reflective sticker is placed on the fixture 2, the suction force of the negative pressure area can firmly adsorb the reflective sticker onto the fixture 2, thereby fixing the reflective sticker. This adsorption method can effectively prevent the reflective sticker from bending and deforming during the application process, ensuring the flatness of the reflective sticker. Then, simply press the light guide plate onto the adhesive surface of the reflective sticker to complete the assembly of the reflective stickers at the edge of the light guide plate.

[0026] In this embodiment, the fixture 2 includes a fixture plate 21, which is mounted on the support 1. A cavity is provided inside the fixture plate 21. Multiple spaced limiting grooves 22 are provided on the top surface of the fixture plate 21 along its length for placing reflective stickers. The limiting grooves 22 are connected to the cavity. The fixture plate 21 is used to connect to a negative pressure pump. A suction force is generated in the limiting grooves 22 through the cavity to adsorb the reflective stickers.

[0027] In this embodiment, the bottom wall of the limiting groove 22 is provided with a plurality of spaced adsorption holes 221 along its length. Under the action of the negative pressure pump, a suction force is formed in the adsorption holes 221. When the reflective sticker is placed in the limiting groove 22, the suction force generated by the adsorption holes 221 can act evenly on the bottom of the reflective sticker, thereby firmly adsorbing the reflective sticker in the limiting groove 22. This uniform adsorption force distribution can effectively prevent the reflective sticker from deforming due to uneven local stress during the adsorption process, ensuring that the reflective sticker remains flat throughout the entire adsorption and attachment process.

[0028] In this embodiment, an air inlet 23 is provided on the edge of the top surface of the support 1, and the air inlet 23 is used to connect to the pipe on the vacuum pump. When the vacuum pump draws air through the air inlet 23, the air enters the cavity inside the support 1 from the air inlet 23, and then is transmitted to the adsorption hole 221 in the limiting groove 22 through the cavity in the fixture plate 21. A negative pressure is formed at the adsorption hole 221. This design makes the generation and transmission of negative pressure more stable, ensuring that the reflective sticker can be firmly adsorbed in the limiting groove 22. At the same time, the design of the air inlet 23 also facilitates the connection and operation with external vacuum equipment, improving the ease of use and reliability of the entire fixture.

[0029] In this embodiment, support legs 101 are installed around the bottom of the support 1, and the support legs 101 are cylindrical to form a support structure for the support 1; to avoid shaking or tilting caused by uneven ground or external force. This stable support structure can effectively improve the accuracy and stability of the reflective sticker application process, reduce the application error caused by equipment instability, and thus improve the quality and consistency of the product.

[0030] In this embodiment, a rubber pad is integrally connected to the bottom surface of the support leg 101. The function of the rubber pad is to increase the friction between the support leg 101 and the ground, further improving the stability of the support 1. At the same time, the rubber pad also has a certain buffering effect, which can absorb the vibration generated by the equipment during operation and reduce the impact of vibration on the reflective sticker application process. This design not only improves the stability of the equipment, but also extends the service life of the equipment and reduces the maintenance cost of the equipment.

[0031] The specific working principle of this utility model is as follows:

[0032] Place the support 1 on a stable workbench, ensuring that the support leg 101 is in good contact with the ground. The rubber pad serves as an anti-slip and cushioning device. Install the fixture 2 on the support 1, ensuring that the connection between the fixture 2 and the support 1 is secure. Connect the vacuum pump pipe to the support 1 through the air inlet 23, ensuring a tight connection and no air leakage. When the vacuum pump starts, air enters the cavity inside the support 1 through the air inlet 23, and then passes through the cavity inside the fixture plate 21 to the adsorption hole 221 in the limiting groove 22, where a negative pressure is formed.

[0033] The reflective stickers are placed sequentially in the limiting grooves 22 of the fixture plate 21. The design of the limiting grooves 22 allows the reflective stickers to be accurately placed in the predetermined position. The negative pressure generated by the adsorption holes 221 firmly adsorbs the reflective stickers into the limiting grooves 22, ensuring that the reflective stickers remain flat during the application process and avoiding bending and deformation.

[0034] Place the light guide plate on top of the reflective sticker and apply downward pressure to the light guide plate to make the reflective sticker adhere to the edge of the light guide plate. When assembling the reflective sticker, only the top surface and sides of the light guide plate need to be attached. The subsequent adhesion process can be completed according to the above method. Since the reflective sticker has been kept flat during the adsorption process, the adhesion process is smoother and can effectively reduce the problems of light leakage and reduced reflection effect.

[0035] After one light guide plate is attached, a new reflective sticker can be placed to continue attaching the next light guide plate. The entire process does not require manual alignment, saving time and labor costs, and is suitable for large-scale production tasks.

[0036] The embodiments of the present utility model have been described above, but the present embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present embodiments, all of which are within the protection scope of the present embodiments.
