Description

Technical Field

[0001] The present application relates to the technical field of display module manufacturing, and in particular to a light-shielding tape attaching device. Background Art

[0002] The module light-shielding and easy-to-tear production process is crucial in the field of semiconductor packaging and electronic equipment manufacturing. Under the demand for high-precision and high-reliability products, how to effectively improve the connection strength between FPC (flexible circuit board) and substrate? The industry uses T-shaped light-shielding tape as a solution. With its unique structural design, this tape can significantly improve the adhesion strength of FPC and ensure stability and durability in complex environments and dynamic usage conditions.

[0003] Although T-shaped light shielding tape has made great improvements in enhancing the pull-out force of FPC and improving the overall performance and reliability of the product, it still faces a technical problem that needs to be solved in the actual production process. Figure 1 Due to the diversity and complexity of product design, some models of modules have an inevitable gap between the FPC and the mounting surface, forming an obvious step structure. This structural feature has caused significant trouble in the process of attaching the light-shielding tape: the traditional flat suction head can ensure the basic adsorption flatness when absorbing the light-shielding tape, but when faced with the step structure, it cannot achieve a comprehensive and tight fit of the tape to the FPC. Therefore, the light-shielding tape often cannot be completely smoothed to the surface of the FPC, causing the light-shielding edge to warp, which not only affects the appearance of the product, but more importantly, directly weakens the FPC's function of enhancing the pulling force.

[0004] Therefore, it is particularly important to develop a new type of light-shielding tape attaching device that can solve the problem of uneven attachment of light-shielding tape on step structures. It needs to have the ability to flexibly adjust the adsorption and attachment methods to adapt to the differentiated needs of different product structures and ensure that the light-shielding tape can fit tightly and evenly on the FPC surface. Summary of the invention

[0005] The purpose of the present application is to provide a light-shielding tape attaching device, which uses wind power to smooth the product without damaging the product, and can be realized by simply modifying the existing production line. The light-shielding tape attaching device of the present application includes a transmission component and a wind knife mechanism; The transport component is used to transport the product between different processing stations; The wind knife mechanism has a linear air outlet, through which a linear smoothing airflow is formed on the transmission component; The shortest distances between each position on the linear air outlet and the product on the transmission component are equal, and the extension direction of the linear smoothing airflow intersects with the transmission direction of the transmission component.

[0009] In one of the embodiments, a product pressing plate is further included, and the product pressing plate is used to fix the product relative to the tray.

[0010] In one of the embodiments, the width of the linear air outlet is less than or equal to 0.2 mm.

[0011] In one embodiment, the width and length of the linear air outlet are adjustable.

[0012] In one of the embodiments, it also includes an adsorption head, which includes at least one adsorption surface for adsorbing the shading tape for transfer and placement.

[0013] In one embodiment, the wind knife mechanism is arranged at the next station of the adsorption head placement station.

[0014] In one of the embodiments, the adsorption head also elastically presses the light-shielding tape through the adsorption surface.

[0015] Compared with the prior art, the present application has the following beneficial effects: the present application provides a shading tape attaching device, which realizes lossless attachment through wind smoothing, generates a uniform and concentrated smoothing airflow through the linear air outlet of the wind knife mechanism, directly acts on the product surface on the transmission component, avoids the damage to the product that may be caused by traditional mechanical pressing, ensures the integrity of the product surface during the shading tape attachment process, effectively eliminates the warping phenomenon that may occur after the tape is attached, and improves the appearance quality and functionality of the product.

[0016] Furthermore, through the design of the air outlet, the airflow is ensured to be stable, more concentrated and directional, avoiding the diffusion and turbulence of the airflow, which not only improves the smoothing effect, but also reduces unnecessary energy consumption, achieving high efficiency and energy saving. In addition, the adjustability of the width and length of the air outlet further enhances the adaptability and flexibility of the device, and can meet the attachment requirements of products of different sizes and shapes.

[0020] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] When faced with complex product structures, traditional attachment methods often cause a series of problems, such as shading warping, because they cannot effectively smooth the tape to a specific surface, which affects the performance and market competitiveness of the product. In order to solve this technical problem, this application proposes a new shading tape attachment device, which introduces wind smoothing technology, combines mechanical design and intelligent control, and achieves efficient and accurate attachment of shading tape on complex product structures. It can not only overcome the limitations of traditional methods, but also significantly improve production efficiency and product quality. Please refer to Figures 2 to 3 As shown, a light-shielding tape attaching device in a preferred embodiment of the present application includes a transmission component 100 and a wind knife mechanism 200. The transmission component 100 is used to transmit products between different processing stations. The wind knife mechanism 200 has a linear air outlet, through which a linear smoothing airflow is formed on the transmission component 100, wherein the shortest distance between each position on the linear air outlet and the product on the transmission component 100 is equal, and the extension direction of the linear smoothing airflow intersects with the transmission direction of the transmission component 100.

[0024] The transmission component 100 is responsible for smoothly and accurately transferring the products to be processed from one processing station to the next, ensuring the continuity and stability of the production process. Its design can take into account the shape, size and transmission speed of the product to ensure that the product maintains the correct posture during the transmission process, which is convenient for subsequent operations. The wind knife mechanism 200 forms a uniformly distributed linear smoothing airflow above the transmission component 100 through its unique linear air outlet design. The shortest distance from each position on the linear air outlet to the product on the transmission component 100 is precisely controlled to be equal, which ensures that no matter where the product is located, it can be subjected to the same intensity of wind force, thereby achieving comprehensive and uniform smoothing of the light-shielding tape. In addition, the extension direction of the linear smoothing airflow is set to intersect with the transmission direction of the transmission component 100. This setting forms a similar air curtain. When the transmission device transports the product, the product will be evenly smoothed by the wind, which enhances the pressing effect of the airflow on the product surface, and also helps to fit the tape more closely to the product surface, reducing the generation of bubbles and wrinkles. Various parameters of the wind knife can be adjusted. By precisely controlling the working parameters of the wind knife mechanism 200, such as wind speed, wind pressure, and blowing time, the degree of wind pressure can be further adjusted to meet the attachment requirements of products of different materials and shapes, ensuring that each attachment can achieve the best effect. The uniform linear smoothing airflow effectively eliminates the bubbles and wrinkles that may be generated during the tape attachment process, significantly improving the attachment quality and appearance of the product. By adding the wind knife mechanism 200 to the production line, the automated transmission component 100 is combined with the wind knife mechanism 200. This method requires little modification to the production line, and the production line can process samples without step differences at the same time. It can be adjusted according to the attachment requirements of different products. It has strong adaptability and versatility, and can achieve compatibility with different types of products through simple improvements.

[0025] Specifically, the transmission device includes a tray 300 and a conveyor belt, and the product is placed on the tray 300 for transmission. In a specific embodiment, the transmission device is designed to include a tray 300 and a conveyor belt. Such a design can enhance the stability and flexibility during the attachment process of the light-shielding tape. The tray 300 is used as a direct bearing platform for the product, and its surface can be specially treated to ensure good contact and anti-slip performance with the product. The product is accurately placed on the tray 300 and is smoothly transferred to each processing station on a predetermined path with the continuous movement of the conveyor belt. The combination of the tray 300 and the conveyor belt simplifies the complexity of product transmission and improves the stability and accuracy of the transmission process. The conveyor belt is made of high-strength, wear-resistant materials, and can withstand products of various sizes and weights while maintaining a stable transmission speed. By accurately controlling the driving device of the conveyor belt, the product transmission speed and position can be accurately regulated to ensure that the product can reach the designated attachment position at the best time. In addition, the design of the tray 300 also fully considers the shape and size changes of the product. By adjusting the size and shape of the tray 300 or adding auxiliary fixtures, it can meet the transportation requirements of products of different specifications and types. This flexible and changeable design enables the transmission device to perform optimally in a variety of production environments.

[0026] In a further design, the air knife mechanism 200 further includes an auxiliary pressure plate 210, which is used to press the tray 300 so that the tray 300 is relatively fixed to the air knife mechanism 200. The auxiliary pressure plate 210 is used to press the tray 300 placed on the transmission device to ensure that a relatively stable contact interface is formed between the tray 300 and the air knife mechanism 200, thereby enhancing the stability of the tray 300 under the action of the air knife, and reducing the position deviation caused by vibration or air flow disturbance, further improving the accuracy and consistency of product processing. The auxiliary pressure plate 210 is made of lightweight and high-strength material, which ensures sufficient downward pressure to achieve stable contact while avoiding unnecessary damage to the tray 300 and the product due to excessive weight. Its structural design often matches the shape of the tray 300, and achieves a close fit with the tray 300 through an adjustable fixing device or elastic elements such as a spring, while allowing a certain degree of adaptability to accommodate trays 300 of different sizes and shapes.

[0027] Specifically, the air outlet direction of the linear air outlet is perpendicular to the transmission direction. The linear air outlet adopts a linear design to ensure uniform distribution of airflow and flow with minimum resistance. At the same time, with the precise adjustment mechanism, the user can accurately adjust the wind direction according to actual needs, meet diverse ventilation or cooling needs, and improve the running stability of the equipment. The design of the linear air outlet perpendicular to the transmission direction allows the airflow to maintain linear motion during the transmission process, reducing the energy loss caused by the change of direction, thereby significantly improving the efficiency of air flow.

[0028] Specifically, it also includes a product pressing plate, which is used to relatively fix the product and the pallet 300. The product pressing plate is made of high-strength, corrosion-resistant materials to ensure that it can effectively resist external impact and vibration during long-term use or transportation. Through an adjustable or locking mechanism, the product pressing plate can fit the surface of the product tightly to meet the needs of products of different shapes and sizes. The product pressing plate is combined with an auxiliary pressing plate 210 to relatively fix the product and the pallet 300. The wind knife mechanism 200 can better avoid the movement of the pallet 300 and the product during the smoothing operation, so that the smoothing operation performed by the wind knife mechanism 200 can be more accurately aligned.

[0029] Specifically, the width of the linear air outlet is less than or equal to 0.2mm. By reducing the width of the air outlet, we can achieve a more concentrated and high-speed airflow injection. The narrower linear air outlet can produce a more concentrated and precise airflow, which enables the airflow to act more accurately on the target area when attaching the light-shielding tape, reducing interference with non-target areas, thereby improving the precision and accuracy of attachment. The concentrated airflow is sprayed onto the surface of the product at high speed, which can effectively smooth out the tiny bubbles and wrinkles under the tape, making the tape fit more closely to the product, enhancing the flatness and aesthetics of the attachment. Although reducing the width of the air outlet may increase the airflow speed requirement to a certain extent, since the airflow is more concentrated, it can reduce the overall airflow consumption while maintaining or improving the smoothing effect, thereby reducing energy consumption.

[0030] In order to improve flexibility and customizability, the design of the wind knife mechanism 200 adopts a technical solution that the width and length of the linear air outlet can be adjusted. The adjustable width and length of the linear air outlet allow the user to flexibly adjust the size of the air outlet according to the specific application scenario, material characteristics and attachment requirements to achieve the best attachment effect. The adjustable width and length of the linear air outlet means that the wind knife mechanism 200 can cope with a variety of attachment tasks. Whether it is the attachment of wide-width materials or precise operation in a small space, the user can adapt by adjusting the size of the air outlet, which greatly enhances the adaptability and flexibility of the equipment. According to different materials and attachment requirements, adjusting the width and length of the air outlet can optimize the distribution and intensity of the airflow. For example, a narrower air outlet can produce a more concentrated and high-speed airflow, which is suitable for scenes that require high-precision attachment; while a longer air outlet can provide a larger coverage area, which is suitable for the attachment of large-area materials.

[0031] In order to further improve the automation and accuracy of the shading tape processing, the present application incorporates an adsorption head 400 module, that is, the device also includes an adsorption head 400, which includes at least one adsorption surface for adsorbing the shading tape for transfer and placement. The adsorption head 400 integrates at least one high-performance adsorption surface. These adsorption surfaces are precision-machined and have excellent adsorption and release properties. They can easily adsorb the shading tape and ensure the stability and accuracy of the tape during the transfer and placement process. The introduction of the adsorption head 400 greatly simplifies the transfer and placement process of the shading tape, and realizes full automation from grasping to positioning. By accurately controlling the adsorption force and release timing of the adsorption surface, the stability and accuracy of the shading tape during the transfer process can be ensured, and the attachment deviation caused by human operation or mechanical errors can be reduced. The design of the adsorption head 400 has certain versatility and flexibility, and can be adapted and adjusted according to shading tapes of different shapes, sizes and materials to meet the diverse needs of different production lines.

[0032] In order to optimize the production process and ensure that the transfer process of the shading tape from the adsorption head 400 to the target position is smoother and more efficient, the wind knife mechanism 200 is set at the next station of the adsorption head 400 placement station. The wind knife mechanism 200 is set at the next station of the adsorption head 400 placement station, so that the shading tape can be immediately processed by the wind knife mechanism 200 after being accurately placed by the adsorption head 400, such as removing bubbles, adjusting the position, etc., thereby enhancing the continuity and smoothness of the entire production process. The wind knife mechanism 200 is set at the next station of the adsorption head 400 placement station, so that the shading tape can be immediately processed by the wind knife mechanism 200 after being accurately placed by the adsorption head 400, such as removing bubbles, adjusting the position, etc. Since the wind knife mechanism 200 is closely connected to the adsorption head 400 placement station, the waiting time and additional operations of the shading tape during the transfer process are reduced, thereby improving the overall production efficiency.

[0033] In the process of further optimizing the light-shielding tape attachment process, the adsorption head 400 is further designed to have an elastic pressing function. The adsorption head 400 also elastically presses the light-shielding tape through the adsorption surface. Specifically, the adsorption head 400 can apply a moderate elastic pressing force while accurately adsorbing the light-shielding tape through its unique adsorption surface. Faced with attachment surfaces of different materials, different shapes, and possible minor defects, the elastic pressing function of the adsorption head 400 shows extremely high adaptability, and can adjust the pressing force and angle according to the actual conditions of the surface, ensuring that the light-shielding tape can achieve a good attachment effect on various complex surfaces. The elastic pressing function of the adsorption head 400 enables the production line to easily cope with the attachment needs of light-shielding tapes of different specifications and materials, thereby improving the versatility and compatibility of the production line.

[0034] As can be seen from the foregoing, the present application provides a highly efficient light-shielding tape attaching device, which integrates a transmission component and a wind knife mechanism. The wind knife mechanism is equipped with a linear air outlet, and by precisely controlling the shortest distance from each position to the product to be equal, a uniformly distributed linear smooth airflow is formed. The airflow intersects with the transmission direction to form an effect similar to an air curtain, which effectively eliminates bubbles and wrinkles during the tape attachment process. At the same time, the wind speed, wind pressure, and blowing time of the wind knife mechanism are adjustable, which further improves the adaptability and flexibility of attachment. The transmission component adopts a combination design of a tray and a conveyor belt, which ensures the smooth and accurate transmission of products between different processing stations, improves the continuity of the production process, and enhances the stability and flexibility of the product transmission process.

[0035] In addition, the introduced adsorption head module can easily adsorb and accurately place the shading tape, realizing full automation from grabbing to positioning. The adsorption head also has an elastic pressing function, which can appropriately press the tape on the adsorption surface to enhance the fit between the tape and the product surface. Furthermore, the device adopts a modular design, and the transmission components, wind knife mechanism and adsorption head module can be flexibly configured and adjusted according to actual needs. In particular, the linear air outlet width and length of the wind knife mechanism are adjustable, so that the device can cope with a variety of attachment tasks, enhancing the adaptability and flexibility of the equipment. By setting the wind knife mechanism at the next station after the adsorption head placement station, the seamless connection from adsorption to smoothing of the shading tape is achieved, which reduces waiting time and additional operations and improves overall production efficiency. At the same time, the close cooperation and automated control between the modules ensure the continuity and smoothness of the production process.

[0036] The shading tape attaching device proposed in this application realizes the high efficiency, precision and automation of the shading tape attaching process by integrating innovative transmission components, wind knife mechanisms and adsorption head modules, which not only improves the attachment quality and appearance of the product, but also reduces production costs and manual labor intensity.

[0037] The above is only a specific implementation of the present application, and any other improvements made based on the concept of the present application are deemed to be within the protection scope of the present application.
