Description

Technical Field

[0002] In recent years, LCD monitors, with their superior characteristics such as high image quality, efficient space utilization, low power consumption, and no radiation, have gradually become the mainstream in the television market. The bezel design of LCD monitors needs to take into account multiple requirements such as structural stability, heat dissipation efficiency, and dust resistance.

[0003] Currently, Chinese patent application number CN201820111391.8 discloses a main frame of a back panel of an LCD TV display, including a rectangular ring-shaped frame body. A U-shaped splicing groove is formed along the ring path inside the frame body. The frame body is snapped onto the edge of the display back panel through the U-shaped splicing groove. An anti-pressure frame is integrally provided in the inner ring of the frame body. The anti-pressure frame extends from the outer ring to the inner ring. When the frame body and the display back panel are spliced, the pressing surface of the anti-pressure frame facing the display back panel contacts and presses against the display.

[0004] However, existing frame technologies rarely incorporate effective active cooling channels, making it difficult to address the heat generated by high-performance components. Furthermore, they lack protective mechanisms against dust intrusion, and dust accumulation during long-term use can easily lead to performance degradation or malfunctions. Additionally, the internal functional components of the frame are mostly fixed using traditional adhesives or locks, which are prone to loosening under vibration. Moreover, the assembly process generally relies on manual labor, making it difficult to ensure consistent quality. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention achieves active heat dissipation control of the air duct through the design of the air guide unit: when the equipment is running at high temperature, the system can automatically open the air duct and use efficient airflow to perform powerful heat dissipation; while in dusty environments or when the equipment is in standby, the air duct can be quickly closed to fundamentally prevent dust intrusion. This switching mechanism effectively solves the technical problem of the contradiction between heat dissipation and dust prevention in traditional frame design, enabling the equipment to adapt to more complex and changeable working environments, and greatly extending the service life and operational reliability of internal components.

[0023] This invention employs a multi-fixing scheme combining hot melt adhesive sealing and mechanical locking. It not only utilizes hot melt adhesive to achieve seamless and gapless bonding and sealing around the mesh, effectively preventing air leakage, but also provides a strong rigid connection through subsequent mechanical locking. This structural design enables the entire frame assembly to effectively resist the influence of external forces such as vibration and impact, ensuring structural integrity and connection reliability under long-term use, and is particularly suitable for applications with high stability requirements.

[0024] The preparation method of this invention optimizes the use of a heat-sealing mechanism, which integrates precise heating, pressing and cooling functions. By replacing traditional manual assembly with automated operation, it can ensure uniform heating temperature of hot melt adhesive, constant and controllable pressing force, and efficient and consistent cooling process. This ensures the accuracy of mesh bonding position and uniformity of sealing quality in each product. It not only greatly reduces quality fluctuations caused by human operation and improves production yield and efficiency, but also ensures the uniformity and reliability of product performance, which is conducive to large-scale standardized production.

Detailed Implementation

[0034] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0035] Please see Figures 1-4 This invention provides a frame with ventilation and heat dissipation channels, including a connecting frame 1, a bottom frame 2, a buffer plate 3, a first rectangular groove 4, a second rectangular groove 5, and a flow guiding unit 6. The bottom frame 2 is provided on the front bottom side of the connecting frame 1, forming the main support structure of the frame and providing the main installation base. A buffer plate 3 is fitted to the front side of the connection between the connecting frame 1 and the bottom frame 2 to absorb and buffer possible impact forces and protect the internal structure of the frame. The first rectangular groove 4 and the second rectangular groove 5, which are of the same structure and size, are symmetrically opened on the left and right sides inside the connecting frame 1 to ensure the balance of heat dissipation and airflow. A rectangular window that runs through the front and rear sides is opened at the rear of the first rectangular groove 4, and the area of ​​the rectangular window is smaller than the area of ​​the first rectangular groove 4. A rectangular window serves as an airflow window to facilitate airflow in and out, while the small window area helps prevent large particles of foreign matter from entering. A mesh 41 is installed inside the first rectangular groove 4 near the rectangular window, and a hot melt adhesive sheet 42 is bonded to the outer periphery of the mesh 41. The rear side of the hot melt adhesive sheet 42 is bonded to the first rectangular groove 4, and a flow guiding unit 6 is attached to the front side of the hot melt adhesive sheet 42. The flow guiding unit 6 is locked and fixed to the first rectangular groove 4 on all four sides. The mesh 41 allows airflow while effectively blocking dust and debris. It is fixed and sealed by heating with the hot melt adhesive sheet 42, simplifying the installation process and preventing airflow leakage. Finally, a strong rigid connection is provided by mechanical locking to ensure the stability of the flow guiding unit 6 under vibration and other working conditions.

[0036] The connection between the adapter frame 1 and the bottom frame 2 is a sloping surface that slopes downwards from back to front, and a horizontal strip groove 11 is provided above the sloping surface to conduct airflow. The position of the strip groove 11 is higher than the top side of the bottom frame 2, which avoids the bottom frame 2 from obstructing the airflow in the strip groove 11 and ensures that the airflow channel is unobstructed. There are through grooves 12 on both the left and right sides of the strip groove 11. The two through grooves 12 are respectively opened through the left and right sides of the adapter frame 1, which divert the airflow in the strip groove 11 to the left and right rear directions, forming an effective heat dissipation airflow channel. The bottom side of the first rectangular groove 4 is connected to the inside of the strip groove 11, so that the airflow generated by the flow guiding unit 6 can smoothly enter the strip groove 11, thereby realizing systematic heat dissipation. The hot melt adhesive sheet 42 is rectangular and has a melting point of 110-130℃, which can reliably melt and bond without damaging other components due to excessive temperature.

[0037] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5This invention provides a frame with ventilation and heat dissipation channels. Two airflow guiding units 6 are provided, and the two airflow guiding units 6 are respectively connected to the inside of the first rectangular slot 4 and the second rectangular slot 5 to improve the heat dissipation air volume and efficiency. It is applicable to high heat load scenarios. The airflow guiding unit 6 includes a support plate 61 that is locked and fixed to the first rectangular slot 4 on all four sides. A rectangular opening is provided on the right side of the inside of the support plate 61 to form the main air circulation channel. A first motor is embedded on the left side of the front part of the support plate 61, and the front output shaft of the first motor is connected to the impeller 62. When the first motor rotates, it transmits power to the impeller 62 to generate forced airflow and improve the air circulation rate. The impeller 62 is wrapped around the front half of the first motor to protect the motor and optimize the airflow path.

[0038] A second motor is embedded in the upper front side of the support plate 61, and the output shaft of the second motor is connected to the gear 63. The second motor drives the gear 63 to rotate. The upper and lower sides of the gear 63 are respectively meshed with the upper rack 64 and the lower rack 65. A rectangular plate 66 is fixed to the right front part of the upper rack 64, and a first stop block 67 is fixedly connected to the bottom rear part of the rectangular plate 66. A second stop block 68 is fixedly connected to the left bottom of the lower rack 65. When the gear 63 rotates, the rotational motion is converted into the lateral linear motion of the upper and lower racks. The structure is compact and the transmission is precise. The first stop block 67 and the second stop block 68 move closer or further apart to realize the opening and closing control of the air duct.

[0039] The support plate 61 has a horizontally arranged strip rod 611 on the upper front side. The tops of the second stop 68 and the first stop 67 are respectively wrapped and slidable on the left and right sides of the strip rod 611. The strip rod 611 provides guidance and support for the sliding of the two stops, ensuring smooth movement without deviation. The rear sides of the second stop 68 and the first stop 67 are in contact with the support plate 61, which further enhances the stability of the movement of the two stops and plays a sealing role. When the second stop 68 and the first stop 67 approach each other, they block and close the rectangular opening of the support plate 61, realizing the closure of the air duct in the non-heat dissipation state, effectively preventing dust intrusion, and combining the functions of heat dissipation and dust prevention.

[0040] In the above, the frame with ventilation and heat dissipation channels mainly achieves efficient heat dissipation and intelligent dust prevention for the TV screen through the synergistic effect of the internal air duct system and the active control of the air guiding unit. The downward sloping surface at the connection between the adapter frame 1 and the bottom frame 2 and the high-position design of the strip groove 11 can avoid the accumulation of foreign objects and ensure smooth airflow. The heat of the TV screen can be discharged from the inside of the channel 12 through the strip groove 11. When the temperature of the TV screen is too high, the air guiding unit 6 is driven to work: the fan wheel 62 in the air guiding unit 6 rotates under the drive of the first motor to generate forced airflow. The airflow is drawn in from the rectangular window at the rear of the first rectangular groove 4 and the second rectangular groove 5, filtered by the mesh 41, and passes through the rectangular opening of the support plate 61. Then, the airflow enters the main air duct strip groove 11 through the connection between the bottom of the first rectangular groove 4 and the second rectangular groove 5 and the strip groove 11. The strip groove 11 splits the airflow to the left and right, and finally it is discharged from the channel 12 on both sides to form a complete directional heat dissipation airflow path, which effectively reduces the internal temperature of the equipment.

[0041] When the equipment does not require heat dissipation or is in a dusty environment, the second motor drives the gear 63 to rotate, causing the meshing upper rack 64 and lower rack 65 to drive the first stop block 67 and the second stop block 68 to slide towards each other along the bar 611 until the two contact and completely block the rectangular opening of the support plate 61, thereby closing the air duct and preventing dust from entering.

[0042] Please see Figures 1-8 This invention provides a method for preparing a frame with ventilation and heat dissipation grooves, which includes the following steps:

[0043] S1. The transition frame 1 and the bottom frame 2 are formed by extrusion and milling processes, and the first rectangular groove 4, the second rectangular groove 5, the strip groove 11, the through groove 12 and the inclined structure are machined on the transition frame 1.

[0044] S2. Place the mesh 41 in the first rectangular groove 4 and the second rectangular groove 5 so that it is close to the rectangular window. Then cover the mesh 41 and the groove wall surface of the first rectangular groove 4 or the second rectangular groove 5 with hot melt adhesive sheet 42 to provide material for the next step of hot bonding and to ensure the effective area of ​​bonding by covering.

[0045] S3. The hot melt adhesive sheet 42 is heated using a heat sealing mechanism. The heating temperature is higher than the melting point of the hot melt adhesive sheet 42, causing it to melt. The melted hot melt adhesive sheet 42 adheres to the periphery of the mesh 41 and fixes it in the groove of the first rectangular groove 4 or the second rectangular groove 5, achieving a seamless, firm and sealed fixation of the mesh 41. Then, the flow guiding unit 6 is placed in the first rectangular groove 4 and the second rectangular groove 5, so that it contacts the front surface of the hot melt adhesive sheet 42. The hot melt adhesive sheet 42, which has not been completely cooled, is used for pre-positioning. After cooling, they are bonded and fixed to each other to form pre-positioning and sealing, which facilitates the subsequent locking operation and also enhances the overall sealing performance.

[0046] S4. Lock and fix the pre-installed flow guiding unit 6 to the first rectangular groove 4 and the second rectangular groove 5 to provide a final reliable mechanical connection. Then, install the buffer plate 3 on the front side of the connection between the adapter frame 1 and the bottom frame 2 to complete the assembly and preparation of the frame.

[0047] In step S3, the heating temperature is controlled at 120℃±10℃ and the heating time is 5-15 seconds to ensure that the hot melt adhesive sheet 42 is fully melted and flowed to achieve the best bonding effect. At the same time, it avoids the temperature from being too high, which may cause the adhesive to deteriorate or the surrounding parts to be damaged by heat. After the flow guiding unit 6 is placed and bonded and fixed, it is cooled to room temperature by forced air cooling before the locking and fixing operation in step S4 is performed. This ensures that the final locking is performed after the adhesive is completely cured and the dimensions are stable, so as to avoid the internal stress causing the connection to loosen or the parts to deform.

[0048] The heat-sealing mechanism includes a top cover 71, with a housing 72 locked and fixed to the rear left side of the top cover 71. A stacking structure 73 is connected inside the top cover 71 to achieve precise lifting and lowering of the heat-sealing head. The rear left side of the stacking structure 73 extends through the housing 72. The bottom left and right sides of the stacking structure 73 are connected to a bottom cover 74. The bottom of the bottom cover 74 is fastened to a support piece 75. The movement of the stacking structure 73 is transmitted to the bottom, achieving precise adjustment of the height of the support piece 75. Near the outer periphery of the bottom of the support piece 75, there is a... The rectangular heating strip 77 provides a concentrated and uniform heat source, ensuring that the hot melt adhesive sheet 42 is heated evenly and melts fully. Fans 76 are embedded on both the left and right sides of the support 75 to achieve forced cooling of the working area, accelerate the curing of the hot melt adhesive sheet 42, and thus improve production efficiency. A pressing structure 78 is installed on the bottom center of the support 75 to hold the mesh sheet 41 against it when the hot melt adhesive sheet 42 melts. During heating, the mesh sheet 41 is pressed tightly to prevent it from shifting due to the melting of the adhesive or the influence of airflow, thus ensuring installation accuracy and bonding quality.

[0049] The stacking structure 73 includes a bracket 731 fixed inside the right side of the compartment cover 72. A servo motor 732 is locked inside the right side of the bracket 731. The top output shaft of the servo motor 732 is connected to a worm gear 733. A worm wheel 734 is meshed and driven on the left side of the worm gear 733. The top of the worm gear 733 is rotatably connected to the bracket 731. Through the self-locking function of the worm gear 733 and the worm wheel 734, it is ensured that the heat-sealing head will not fall down due to gravity when it stops at any position. The rotating shaft on the middle front side of the worm wheel 734 passes through and rotates on the front side of the compartment cover 72. The front end of the rotating shaft rotates coaxially with the first long rod 735 to output power to the first long rod 735 and convert the rotational motion into the swinging motion of the first long rod 735.

[0050] The bottom end of the first long rod 735 is rotatably connected to the second long rod 736. The front side of the connection between the first long rod 735 and the second long rod 736 is connected to the third long rod 738 via an upper short rod 737. The bottom end of the third long rod 738 is connected to the second long rod 736 via a lower short rod 739. A fourth long rod 7310 is rotatably connected to the front side of the connection between the third long rod 738 and the lower short rod 739. The second long rod 736, the upper short rod 737, the third long rod 738, and the lower short rod 739 constitute a... A stable telescopic quadrilateral structure is constructed. The top ends of the first long rod 735 and the third long rod 738 are rotatably connected to the left and right sides inside the top cover 71, respectively, hinged to the upper end of the entire linkage mechanism inside the top cover 71. The bottom ends of the second long rod 736 and the fourth long rod 7310 are rotatably connected to the left and right sides inside the bottom cover 74, respectively, ultimately transmitting the motion to the bottom cover 74 and the heat sealing head, achieving smooth lifting and lowering motion. This linkage mechanism can provide a large lifting stroke and stable output.

[0051] The pressing structure 78 includes two outer cylinders 781 fixedly connected to the left and right sides of the bottom of the support plate 75. Springs 782 are installed on the top side of the inside of each outer cylinder 781. The bottom of the springs 782 is connected to an inner rod 783, which slides through the middle of the bottom of the outer cylinder 781. The bottom of the two inner rods 783 is fixed to the pressing plate 784. The top two sides of the pressing plate 784 move vertically in a straight line inside the outer cylinder 781 through the inner rods 783 to ensure accurate pressing position. The springs 782 provide continuous and buffered downward pressure, so that the pressure of the pressing plate 784 is evenly applied to the mesh 41, thereby achieving stable pressing and positioning of the mesh 41 and ensuring the installation effect and bonding quality of the mesh 41.

[0052] The working principle of the heat sealing mechanism described above is as follows:

[0053] First, after the servo motor 732 starts, it drives the worm gear 733 to rotate. The worm gear 733 meshes with the worm wheel 734 for transmission. Through the self-locking characteristic, it ensures that the heat sealing head can be reliably locked in any lifting position. When the worm wheel 734 rotates, it drives the first long rod 735 to swing. Through the multi-link stacking structure 73 composed of the second long rod 736, the upper short rod 737, the third long rod 738, the lower short rod 739 and the fourth long rod 7310, the rotational motion is converted into a smooth vertical lifting motion. Finally, it drives the support plate 75, which is equipped with the electric heating strip 77 and the pressing structure 78 at the bottom, to approach the workpiece as a whole.

[0054] Second, when the heat sealing head descends to the working position, the heating strip 77 first heats the hot melt adhesive sheet 42. The heating temperature is precisely controlled within the process requirements range, so that the hot melt adhesive sheet 42 is fully melted. At the same time, the spring 782 in the pressing structure 78 drives the inner rod 783 to drive the pressing plate 784 to continuously press the mesh sheet 41 to prevent it from shifting and ensure the accuracy of the bonding position.

[0055] Third, after heating is completed, the heat sealing head rises, and the fan 76 immediately starts to force-cool the working area, accelerating the curing process of the hot melt adhesive, thereby achieving efficient, precise and firm sealing and fixing of the mesh 41.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
