Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted displays, and in particular to a method for processing a display rear cover. The present invention also relates to a display rear cover and a vehicle-mounted display. Background Art

[0002] MINI-LEDs, or sub-millimeter light-emitting diodes, offer multiple advantages in automotive displays. For example, their high brightness ensures excellent visibility even in bright sunlight, their high contrast and wide dynamic range accurately render image details, their flicker-free design effectively reduces driver visual fatigue, and their local dimming feature enables independent brightness control of different screen areas. These advantages have led to their widespread adoption in a variety of applications, including central control screens, instrument clusters, passenger entertainment screens, and rear-seat entertainment systems.

[0003] Because MINILEDs integrate a large number of LEDs, they generate a lot of heat over time. To address this heat dissipation issue, there are two mainstream solutions: one is to install a cooling fan behind the back cover to dissipate heat through forced convection. However, MINILEDs are relatively thick, and adding a cooling fan would increase the thickness of the entire device and take up more space. The other is to fix the light panel to the back cover, allowing the back cover to come into contact with the air and dissipate heat through natural convection. However, the smooth surface of the back cover creates a laminar flow effect when in contact with the air, resulting in low heat dissipation efficiency. Summary of the Invention

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] An embodiment of the present invention discloses a method for processing a display back cover, comprising the following steps:

[0060] Step S1, clamping the housing fixture, the housing fixture fixes the display rear housing 1 on the housing fixing seat;

[0061] The housing fixtures are evenly distributed along the periphery of the display rear housing 1 and are used to secure the display rear housing 1 to the housing mounting base, accurately positioning the display rear housing 1 and preventing displacement of the display rear housing 1 during processing that could affect processing quality, thereby improving processing accuracy. The housing fixtures can be universal fixtures, and the pressing head of the housing fixture can be a flexible pressing head, such as a rubber pressing head, to avoid leaving an indentation on the display rear housing 1 due to the pressing head.

[0062] Step S2: Adjust the position of the dimple processing device of the surface treatment equipment until the dimple processing device is aligned with the surface to be processed of the display rear cover 1. The surface treatment equipment can be a shot peening device or a laser engraving device. In the case of a shot peening device, for example, the projectiles impact the surface to be processed at high speed, forming heat dissipation grooves. The heat dissipation grooves are specifically arc-shaped grooves, which not only increase the heat dissipation area but also improve the adhesion of subsequent coatings.

[0063] Step S3: The pit processing device processes the surface to be processed along the set trajectory so that the surface to be processed is evenly covered with a plurality of heat dissipation pits 11; wherein all the heat dissipation pits 11 are distributed in a point array, and the actual spacing between two adjacent heat dissipation pits 11 (i.e., the actual distance between the center lines of the two heat dissipation pits 11) is preferably 1.5 mm, and the depth of each heat dissipation pit 11 is 0.5 mm. Figure 3 As shown. It should be noted that the display back cover 1 herein is a one-piece die-cast metal shell. To improve machining accuracy, the surface to be machined can be pre-cleaned before the pit machining device processes the surface to be machined, to prevent stains attached during the die-casting or transfer process from affecting the machining quality.

[0064] Step S4: After the pit processing device leaves the surface to be processed, adjust the posture of the burr cleaning device of the deburring device until the burr cleaning device is aligned with the surface to be processed; wherein, the deburring device can specifically use magnetic polishing or acid corrosion to perform deburring.

[0065] Step S5: The burr removal device removes burrs from the edges and inner walls of all heat dissipation pits 11 along a preset trajectory, reducing airflow resistance on the surface of the heat dissipation pits 11 and maintaining the turbulence enhancement effect on the processed surface, which helps improve heat exchange efficiency. Furthermore, only one clamping is required to continuously perform pit processing and deburring, eliminating one clamping step, reducing ineffective time, and improving processing efficiency.

[0066] The present invention uses surface treatment equipment to process densely distributed heat dissipation pits 11 on the display back cover 1, and then uses deburring equipment to perform all-round burr removal on the edges and inner walls of the pits. This integrated heat dissipation structure design does not require the installation of an additional heat dissipation fan, effectively reducing the occupied space. In addition, the heat dissipation pits 11 in the present invention can not only increase the contact area between the display back cover 1 and the air, improving the heat dissipation efficiency, but also transform the smooth surface into a microscopic rough surface. When air flows through, the air will generate more vortices and turbulence near the heat dissipation pits 11, as shown in the attached figure. Figure 2 As shown, the degree of airflow mixing is increased and the laminar boundary layer of the airflow is destroyed, which makes the thickness of the thermal boundary layer thinner, increases the convective heat transfer coefficient, and improves the heat dissipation efficiency. Therefore, the present invention reduces the occupied space and improves the heat dissipation efficiency by processing the heat dissipation pit 11 on the rear cover 1 of the display.

[0067] The convective heat transfer Q of the heat dissipation pit 11 in the present invention satisfies the following formula:

[0068] ; (1)

[0069] Where Q is the heat dissipation, A is the convection heat transfer coefficient; F is the heat dissipation area; is the surface temperature of the heat dissipation surface; is the ambient temperature.

[0070] As can be seen from formula (1), the provision of heat dissipation pits 11 enables the rough surface of the surface to be processed to have a larger actual surface area than the smooth surface. That is, when the air contacts the rough surface, it can increase the contact area between the display back cover 1 and the air. As can be seen from the above formula (1), the heat dissipation amount Q is proportional to the heat dissipation area F. The heat dissipation pits 11 on the surface to be processed can enable heat to be more effectively transferred from the surface of the display back cover 1 to the air.

[0071] The convective heat transfer coefficient A satisfies the following formula:

[0072] ; (2)

[0073] Where λ is the thermal conductivity of the fluid; δ is the thickness of the convective heat transfer boundary layer;

[0074] It can be seen from formula (2) that the rough surface of the machined surface will cause the air to generate more vortices and turbulence near the wall, increase the degree of air mixing, and also destroy the laminar boundary layer of the airflow, making the thickness of the thermal boundary layer thinner. The boundary layer thickness decreases and the convective heat transfer coefficient increases, that is, the efficiency of heat transfer is improved, the heat dissipation increases accordingly, and the heat dissipation efficiency is higher.

[0075] The convective heat transfer coefficient A also satisfies the following formula:

[0076] ; (3)

[0077] Wherein, v is the fluid velocity of the fluid; β is the thermal conductivity; ρ is the density of the fluid; d is the equivalent diameter; is the specific heat capacity; x is the characteristic length.

[0078] The surface roughness of the machined surface can promote the shear and turbulence of the fluid and increase the flow rate of the fluid. From formula (3), it can be seen that the convective heat transfer coefficient A is proportional to the fluid flow velocity v. As the flow velocity increases, the convective coefficient increases accordingly. Increasing the roughness can make the air flow path more complex, increase the interaction between the air and the rear shell, increase the convective heat transfer coefficient A, and effectively improve the heat dissipation efficiency.

[0079] The display back cover processing method further includes step S6, wherein a cleaning device cleans the surface to be processed to remove residual shot debris, metal dust, grease, and other contaminants from shot blasting to prevent the subsequent coating from affecting adhesion and uniformity. The cleaning method may be a combination of ultrasonic cleaning and alkaline degreasing.

[0080] Step S6: The step of cleaning the surface to be processed by the cleaning equipment includes:

[0081] Step S61: After the burr removal device is away from the heat dissipation pit 11, the housing fixture is removed and the display back cover 1 is removed from the housing mount. That is, before cleaning, the display back cover 1 is removed from the housing mount so that the display back cover 1 can be completely immersed in the cleaning liquid, which is more thorough and conducive to improving the processing quality. Of course, it is also possible to clean only the surface to be processed of the display back cover 1 directly on the housing mount without removing the display back cover 1, which is more efficient.

[0082] Step S62: The transfer device places the clamped display back cover 1 into the cleaning container of the cleaning device, ensuring that the surface to be processed is completely immersed in the cleaning fluid. Before placing the display back cover 1, the liquid level of the cleaning fluid in the cleaning container is pre-detected to determine whether the liquid level is below a set level. If so, the refill pump provided in the refill pipe of the cleaning device is turned on, and the cleaning device replenishes the cleaning fluid through the refill pipe.

[0083] Step S63: Cleaning equipment cleans the stains attached to the surface to be processed to avoid affecting the adhesion and uniformity of the subsequent spraying layer. The cleaning method can refer to the above content and is not specifically limited here.

[0084] Step S64, determine whether the cleaning time of the cleaning equipment reaches the preset cleaning time. If so, the cleaning equipment stops working; if not, the cleaning equipment continues working; automatic stopping of cleaning is achieved, the degree of automation is high, waste is avoided, and processing efficiency is improved.

[0085] The display back cover processing method further includes step S7, wherein a drying device dries the display back cover 1 to remove moisture attached to the surface to be processed, thereby ensuring that the surface to be processed remains absolutely dry to prevent bubbles or peeling after subsequent oil spraying.

[0086] Step S7, drying the display rear cover 1 with a drying device includes:

[0087] Step S71: When the drying chamber of the drying equipment is preheated to a set temperature, the transfer device transfers the cleaned display rear cover 1 into the drying chamber; wherein the set temperature is between 120° C. and 180° C. The transfer device herein may be a robotic arm equipped with movable rollers, but is not limited thereto.

[0088] S72. The drying equipment dries the display rear cover 1 to completely remove moisture from the surface to be processed.

[0089] S73. Determine whether the drying time of the drying device has reached the preset drying time. If so, the drying device stops working; if not, the drying device continues working, so that the drying device automatically stops, which is beneficial to reducing energy consumption. In this article, the preset drying time is 10-20 minutes.

[0090] The above display back cover processing method further includes step S8, in which an oil spraying device sprays oil on the surface to be processed to form an insulating oil film, which effectively blocks water vapor and oxygen and improves the corrosion resistance of the surface to be processed.

[0091] Step S8, the oil spraying device sprays oil on the surface to be processed, including:

[0092] Step S81 : The transfer device transfers the dried display back cover 1 to the housing fixing seat, eliminating the need for manual transfer of the display back cover 1 , thereby avoiding uneven oil spraying due to manual misoperation.

[0093] Step S82: Clamp the housing fixture to fix the display rear housing 1 to the housing fixing seat to ensure that the display rear housing 1 remains stationary during the oil spraying process, so that the thickness of the oil film attached to the surface to be processed is more uniform.

[0094] Step S83: Adjust the position of the oil spray gun of the surface oil spraying equipment until the oil spray gun is aligned with the surface to be processed, thereby reducing oil waste and achieving efficient oil spraying.

[0095] Step S84: The oil spray gun sprays oil on the surface to be processed along the specified trajectory until the oil completely coats the surface to be processed, so that an insulating oil film of uniform thickness is formed on the surface to be processed.

[0096] The display back cover processing method further includes step S9, wherein a drying device is used to dry the display back cover 1 after oil spraying. This secondary drying process ensures that the insulating oil film is reliably adhered to the surface to be processed. During the secondary drying process, it is necessary to ensure that the display back cover 1 is evenly heated, reduce the shrinkage stress of the insulating oil film, avoid cracking or orange peel phenomenon of the insulating oil film, and effectively improve the processing quality of the surface to be processed.

[0097] Step S9, drying the display back cover 1 after oil spraying with a drying device includes:

[0098] Step S91: After the oil spray gun is away from the surface to be processed, the housing fixture is removed and the display rear housing 1 is removed from the housing fixing seat;

[0099] Step S92: When the drying chamber is preheated to a preset temperature, the transfer device transfers the oiled display back cover 1 into the drying chamber; the preset temperature in this article refers to the optimal temperature for drying the insulating oil film on the surface to be processed, which can be adjusted according to the oil composition and is not specifically limited here.

[0100] Step S93: Drying the display back cover 1 with a drying device;

[0101] Step S94: Determine whether the drying time of the drying device has reached the set drying time. If so, the drying device stops working; if not, the drying device continues working. Automatically stopping the drying device is beneficial to reducing energy consumption. In this article, the drying time is set to 10-20 minutes.

[0102] As a preferred embodiment, step S3, the pit processing device processes the surface to be processed along the set trajectory so that the surface to be processed is evenly covered with a plurality of heat dissipation pits 11, further comprising:

If so, the locking device fixes the positioning panel; if not, repeat step S11; by accurately adjusting the position of the positioning panel, the tilt angle of the surface to be processed is accurately adjusted to ensure that the surface to be processed is aligned with the pit processing device, thereby improving the processing accuracy.
