Description

Technical Field

[0001] The invention belongs to the technical field of LED display screens, in particular to an LED display screen with a sound-transmitting structure and a detection device thereof. Background Art

[0002] The sound-transmitting LED display is an innovative product that combines LED display technology and sound-transmitting technology. Based on the traditional LED display, it achieves sound penetration through special design, thus solving the limitations of traditional LED displays in sound propagation. Its working principle usually involves embedding LEDs in mesh or microporous materials so that sound can be transmitted through the holes, while LED lights are emitted from these areas.

[0003] At present, the sound holes of LED display screens are round holes. However, when in use, especially outdoors, dust can easily enter the interior of the LED display screen through the sound holes. The long-term accumulation of dust can easily cause damage to the internal components of the LED display screen. Secondly, the sound holes of LED display screens are currently opened in multiple locations. Although the design of multiple sound holes can improve the sound transmission effect, in some cases (such as outdoor environments with high noise), too many sound holes may become noise "amplifiers" and affect the audience's auditory experience. In addition, opening sound holes in multiple locations will increase the difficulty of sealing the entire display screen.

[0004] Secondly, during the production of these LED displays, testing equipment is also needed to test the LED displays, such as brightness testing, which can improve the quality of LED displays before leaving the factory.

[0005] In a Chinese patent with publication number CN114279692B, a detection method for a brightness detection device for an LED display screen is mentioned, comprising a main slide plate, a brightness meter is fixedly connected to the upper surface of the main slide plate, a sub-slide plate is fixedly connected to the rear of the main slide plate, a classification device is arranged at the front of the main slide plate, a collection box is fixedly connected to the right side of the main slide plate, a collection device is fixedly connected to the inner wall of the collection box, a rotating plate is rotatably connected to the inner wall of the main slide plate, a conductor is fixedly connected to the upper surface of the rotating plate, the collection device comprises an elastic plate, a transmission rod is fixedly connected to the right side of the elastic plate, and the LED display screen can be moved directly through the inclined surface by tilting the main slide plate and the sub-slide plate.

[0006] However, this method relies on multiple components such as an elastic plate, a transmission rod, an injection slide plate, and a sub-slide plate to recycle the LED display after detection. However, multiple components need to work closely and accurately together to recycle the LED display. Once one of the components goes wrong or a transmission deviation occurs, the LED display cannot be recycled, which increases the risk of dislocation or falling of the LED display due to LED display recycling errors, and increases repeated operations and waiting time due to inaccurate transmission, which reduces the operating efficiency of the entire production line, extends the production cycle, and increases production costs.

[0007] Therefore, those skilled in the art have proposed an LED display screen with a sound-transmitting structure and a detection device thereof to solve the problems raised by the background art. Summary of the invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention sets the sound-permeable hole in an inverted cone shape. First, the inverted cone-shaped sound-permeable hole can ensure that the sound is less obstructed during the propagation process, so that the sound can pass through the LED module more smoothly and reach the audience or listeners. This design reduces the loss of sound during transmission and improves the clarity and volume of the sound. The inverted cone design may also have a certain sound amplification effect, so that the sound is strengthened in a specific direction, thereby improving the audience's auditory experience. Secondly, the inverted cone design of the sound-permeable hole physically forms a barrier, making it more difficult for dust to enter the interior of the LED display under the action of gravity and air flow. This feature is particularly important for outdoor or dusty environments, and can extend the service life of the LED display and reduce maintenance costs. Reducing dust from entering the interior of the display can also protect the internal electronic components from dust and debris.

[0029] 2. The present invention opens inverted cone-shaped sound-permeable holes in the LED module according to the shape of the actual audio equipment. First, the number of openings can be reduced to ensure that the sound can pass smoothly. Secondly, reducing the number of openings means reducing the physical weaknesses on the LED module. Each opening is a potential stress concentration point, which may affect the overall structural strength of the LED display. By reducing unnecessary openings, the durability and impact resistance of the module can be improved, especially during transportation, installation and use, reducing the risk of damage caused by vibration or external force. Secondly, it helps to improve the waterproof and dustproof level of the LED module and protect the internal circuit and electronic components from moisture, corrosion and short circuit. Finally, although the number of sound-permeable holes is reduced, each sound-permeable hole is set to an inverted cone and designed according to the shape of the actual audio equipment to ensure that the sound can pass smoothly and achieve the expected acoustic effect, which helps to reduce the scattering and reflection of sound during propagation, improve the directionality and clarity of sound, and provide a more realistic auditory experience for the audience.

[0030] 3. The present invention sets a conveying component so that the conveyor belt can be retracted. By adjusting the length and position of the conveyor belt, it can ensure that the LED display screen can be accurately sent to the designated recycling rack, reducing the risk of dislocation or falling of the LED display screen due to LED display screen recycling errors, and improving the stability and reliability of the entire production line. The conveyor belt can accurately send the LED display screen to the recycling rack, reducing repeated operations and waiting time caused by inaccurate transmission, which helps to improve the operating efficiency of the entire production line, shorten the production cycle, and reduce production costs.

[0031] 4. The present invention uses a pneumatic lift to adjust the height. When a recycling rack on a certain layer is filled, the pneumatic lift will automatically raise the layer, so that the recycling rack on the next layer moves to the front end of the conveyor belt, waiting to receive a new LED display. This design not only saves space, but also improves the continuity and efficiency of recycling. The layered recycling design can effectively avoid collisions between LED displays. Since each layer of recycling racks is independent, it can ensure that the LED display maintains a stable spacing and position during the recycling process, reducing the risk of damage caused by collisions.

DETAILED DESCRIPTION

[0045] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0046] As attached Figure 1 To Attachment Fig.11 As shown:

[0047] Embodiment 1: The present invention provides an LED display screen with a sound-transmitting structure, which is characterized by comprising:

[0048] LED module 1;

[0049] A sound-transmitting hole 3, wherein a plurality of sound-transmitting holes 3 are provided and each sound-transmitting hole 3 is configured to be an inverted cone;

[0050] A PCB board 4 is installed at the rear end of the LED module 1, and the PCB board 4 is provided with a plurality of holes 5;

[0051] The box body 6 is installed outside the LED module 1 and the PCB board 4 . A bottom shell 8 is fixedly installed at the lower end of the box body 6 . An adhesive layer 9 is provided at the lower end of the bottom shell 8 .

[0052] A plurality of lamp beads 2 are installed inside the LED module 1 .

[0053] The arrangement shape of the plurality of sound-permeable holes 3 and the channel 5 is arranged according to the shape of the audio equipment, and the box body 6 is connected to the LED module 1 through a plurality of mounting bolts 7 .

[0054] As can be seen from the above, by opening an inverted cone-shaped sound-permeable hole 3 in the LED module 1 according to the shape of the actual audio equipment, firstly, the number of openings can be reduced to ensure that the sound can pass smoothly. Secondly, reducing the number of openings means that the physical weaknesses on the LED module 1 are reduced. Each opening is a potential stress concentration point, which may affect the overall structural strength of the LED display. By reducing unnecessary openings, the durability and impact resistance of the LED module 1 can be improved, especially during transportation, installation and use, reducing the risk of damage caused by vibration or external force. Secondly, it helps to improve the waterproof and dustproof level of the LED module 1, and protect the internal circuit and electronic components from moisture, corrosion and short circuit. Finally, although the number of sound-permeable holes 3 is reduced, each sound-permeable hole 3 is set to an inverted cone and designed according to the shape of the actual audio equipment to ensure that the sound can pass smoothly and achieve the expected acoustic effect, which helps to reduce the scattering and reflection of sound during propagation, improve the directionality and clarity of sound, and provide a more realistic auditory experience for the audience.

[0055] The sound-permeable hole 3 is set to an inverted cone shape. First, the inverted cone-shaped sound-permeable hole 3 can ensure that the sound is less obstructed during the propagation process, so that the sound can pass through the LED module 1 more smoothly and reach the audience or listeners. This design reduces the loss of sound during transmission and improves the clarity and volume of the sound. The inverted cone design may also have a certain sound amplification effect, so that the sound is strengthened in a specific direction, thereby improving the audience's auditory experience. Secondly, the inverted cone design of the sound-permeable hole 3 physically forms a barrier, making it more difficult for dust to enter the interior of the LED display under the action of gravity and air flow. This feature is particularly important for outdoor or dusty environments, and can extend the service life of the LED display and reduce maintenance costs. Reducing dust from entering the interior of the display can also protect the internal electronic components from dust and debris.

[0056] By providing an adhesive layer 9 under the bottom shell 8, it is helpful to protect the internal components of the LED display screen and prevent damage caused by external impact. At the same time, the adhesive layer 9 is designed on the bottom shell 8, which can be used to fix audio equipment such as vertical speakers, thereby improving the convenience of installing the LED display screen.

[0057] Embodiment 2: The present invention provides a detection device for an LED display screen with a sound-transmitting structure, comprising:

[0058] A support platform 10, a brightness meter 11 is fixedly mounted on the upper end of the support platform 10;

[0059] A transmission component 12 is installed on the upper end of the support platform 10 and is used for detecting and recycling the LED display screen. The transmission component 12 includes a bracket 121 fixedly installed on the upper end of the support platform 10. A fixed shaft 122 and a fixed shaft 2 123 are relatively rotatably installed inside the rear end of the bracket 121. A main shaft 124 is rotatably installed inside the front end of the bracket 121. Guide rods 125 are fixedly installed on both sides of the bracket 121. Slide racks 126 are slidably installed on the outer surfaces of the two guide rods 125. A support plate 128 is fixedly installed on one side of the two slide racks 126. The support plate 128 is slidably connected to the bracket 121. A moving shaft 129 is rotatably installed on the rear end of the slide rack 126. A moving shaft 2 1210 is rotatably installed on the front end of the slide rack 126. The outer surfaces of the fixed shaft 122, the fixed shaft 2 123, the main shaft 124, the moving shaft 1 129 and the moving shaft 2 1210 are connected by transmission belts 1211.

[0060] A moving mechanism 13, which is mounted on the upper end of the support platform 10;

[0061] The recovery mechanism 14 is provided with two, both of which are arranged at the upper end of the moving mechanism 13. The moving mechanism 13 drives the recovery mechanism 14 to move horizontally. The recovery mechanism 14 includes a pneumatic lifting platform 141, and a recovery frame 142 is placed on the upper end of the pneumatic lifting platform 141.

[0062] The transmission assembly 12 further includes two telescopic cylinders 127 fixedly mounted on both sides of the bracket 121 , and output ends of the two telescopic cylinders 127 are fixedly connected to one side of two sliding frames 126 , respectively.

[0063] A stepper motor 1212 is fixedly mounted on one side of the bracket 121 , and an output end of the stepper motor 1212 is fixedly connected to one end of the main shaft 124 via a coupling.

[0064] The moving mechanism 13 includes a limiting groove 131 fixedly installed on the upper end of the support platform 10, and a threaded rod 132 is rotatably installed inside the limiting groove 131. Two moving plates 134 are relatively slidably installed inside the limiting groove 131. Threaded rings are fixedly penetrated inside the two moving plates 134, and the threaded rings are threadedly connected to the threaded rod 132. The upper end of the moving plate 134 is fixedly connected to the lower end of the pneumatic lifting platform 141.

[0065] A transmission motor 133 is fixedly mounted at one end of the limiting groove 131 , and an output end of the transmission motor 133 is fixedly connected to the threaded rod 132 via a coupling.

[0066] The recovery mechanism 14 further includes a fixing plate 143 fixedly mounted on the upper end of the pneumatic lifting platform 141 .

[0067] A support plate 144 is fixedly installed on the upper end of the pneumatic lifting platform 141, an electric push rod 145 is fixedly installed on one side of the support plate 144, and a clamping plate 146 is fixedly installed on the output end of the electric push rod 145 through the support plate 144, and the clamping plate 146 cooperates with the fixed plate 143 to clamp the recovery frame 142.

[0068] As can be seen from the above, during the production of LED display screens, in order to improve the factory quality of LED display screens, the brightness detection of the LED display screen is very important. When detecting the brightness of the LED display screen, the LED display screen is placed under the brightness meter 11, and the LED display screen is powered on. The brightness meter 11 detects the brightness of the LED display screen, and the result is fed back to the intelligent processing end of the detection device, which determines whether it is a qualified product. The intelligent processing end is used to determine whether it is a qualified product. There are two recycling mechanisms 14, and the two recycling racks 142 are divided into qualified recycling racks 142 and unqualified recycling racks 142. According to the detection results, after the intelligent processing end determines the product quality, it starts the transmission motor 133 to drive the threaded rod 132 to rotate, so that the threaded rod 132 is engaged with the threaded ring inside the movable plate 134, thereby driving the two movable plates 134 to slide inside the limit groove 131, and further drives the two recycling mechanisms 14 to move, so that the corresponding recycling racks 142 are at the front end of the conveying component 12.

[0069] After detection, the LED display screen is pushed onto the conveyor belt 1211, and the intelligent processing end starts the stepper motor 1212, thereby driving the main shaft 124 to rotate, so that the conveyor belt 1211 is transmitted on the outer surface of the fixed shaft 1 122, the fixed shaft 2 123, the mobile shaft 1 129, and the mobile shaft 2 1210 to transport the LED display screen. At the same time, the intelligent processing end starts the telescopic cylinder 127 to push the sliding frame 126 to move forward on the guide rod 125, thereby driving the mobile shaft 1 129 and the mobile shaft 2 1210 moves forward, thereby driving the conveyor belt 1211 to move forward, so that the front end of the conveyor belt 1211 extends into the recycling rack 142 while conveying the LED display screen. The LED display screen is transported by the conveyor belt 1211 and stays on the recycling rack 142. The LED display screen after detection is recycled, and then the conveyor belt 1211 is retracted by the telescopic cylinder 127 to wait for the next transportation. The pneumatic lifting platform 141 is started to push the recycling rack 142 to move upward, so that the LED display screen that has not been placed on the recycling rack 142 is not placed on the recycling rack 142. The recycling layer of the D display screen is at the front end of the conveyor belt 1211, waiting for the next inspection and recycling of the LED display. When the multiple recycling layers of the recycling rack 142 have recycled the LED display screens, the electric push rod 145 is started to drive the clamping plate 146 away from the recycling rack 142, so that the recycling rack 142 is no longer clamped, which further facilitates the staff to carry the recycling rack 142. By setting the transmission component 12, the conveyor belt 1211 can be retracted. By adjusting the length and position of the conveyor belt 1211, it can be ensured that the LED display screen can be accurately sent to the designated recycling rack 142, reducing the risk of dislocation or falling of the LED display screen due to LED display screen recycling errors, and improving the stability and reliability of the entire production line. The conveyor belt 1211 can accurately send the LED display screen to the recycling rack 142, reducing repeated operations and waiting time caused by inaccurate transmission, which helps to improve the operating efficiency of the entire production line, shorten the production cycle, and reduce production costs. The height is adjusted by the pneumatic lifting platform 141. When a recycling rack 142 of a certain layer is filled, the pneumatic lifting platform 141 will automatically raise the layer, so that the recycling rack 142 of the next layer moves to the front end of the conveyor belt 1211, waiting to receive a new LED display. This design not only saves space, but also improves the continuity and efficiency of recycling. The layered recycling design can effectively avoid collisions between LED displays. Since each layer of recycling racks 142 is independent, it can ensure that the LED display maintains a stable spacing and position during the recycling process, reducing the risk of damage caused by collisions.

[0070] Embodiment 3: In combination with Embodiment 1 and Embodiment 2, this device is applied to actual scenarios. Currently, the sound holes of the LED display screen are round holes. However, when in use, especially outdoors, dust can easily enter the interior of the LED display screen through the sound holes. Long-term accumulation of dust can easily cause damage to the internal components of the LED display screen. This device changes the structure and arrangement of the sound holes, thereby reducing the entry of dust into the interior of the display screen, protecting the internal electronic components from dust and debris, and improving the durability and impact resistance of the module.
