Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of LED display, more particularly to a bidirectional transmission integrated LED display screen and a manufacturing method thereof. BACKGROUND

[0002] In the manufacturing process of the conventional integrated LED display screen, the pin functions of each lamp bead are relatively fixed, usually including input pins, output pins and power pins, etc. However, this fixed pin function design leads to waste of copper foil, because in actual application, not all pins will be fully utilized. In addition, the conventional display screen also has limitations in data transmission direction, usually only in one fixed direction for data transmission, which limits the flexibility and application range of the display screen. For example, 2-pin and 5-pin have a pin inside the lamp bead which is empty and does not have any function, which leads to waste of copper wire on the PCB and increases the production cost. At the same time, this design also limits the utilization rate of the lamp bead and reduces the overall performance of the display screen.

[0013] Preferably, it also includes a cutting mechanism, the cutting mechanism includes a machining table; a placing plate arranged on the top of the machining table for placing the PCB board; a driving assembly arranged inside the machining table for driving the placing plate to rotate; a fixing assembly arranged on the side of the machining table for fixing the PCB board on the placing plate; a cutting assembly arranged on the top of the machining table for cutting the side edge of the PCB board; wherein the fixing assembly includes a U-shaped support connected to the driving assembly, the top of the U-shaped support is provided with an electric push rod one, the output end of the electric push rod one is equipped with a pressing disc, and the pressing disc is arranged in the central area of the placing plate.

A pad is fixedly installed in the middle of the push rod, and a spring is inserted through the middle of the push rod at the position between the vertical plate and the pad.

[0019] In summary, the present invention has the following beneficial technical effects:

[0020] 1. By connecting pins 2 and 5 internally, the electronic assembly design saves copper foil, allowing data transmission from either end of the display screen's transmission direction. It also supports breakpoint resume functionality, enabling upstream and downstream components to achieve better display effects using a single pin configuration. This significantly reduces processing costs and improves the utilization rate of LED chips / display screens. Furthermore, it allows for bidirectional transmission using a single LED chip, simplifying the design and production process, improving production efficiency, and reducing waste in line switching, materials, and labor.

[0021] 2. The pressing plate is moved downwards by the electric push rod, making it contact the PCB board, thus fixing the PCB board. Next, the cutting assembly cuts two sides of the PCB board. Then, the drive assembly rotates the placement plate 90 degrees, aligning the other two sides of the PCB board with the cutting assembly, which then cuts the other sides. This structural design achieves stable fixing of the PCB board. This fixing method effectively prevents the PCB board from shifting during the cutting process, thus ensuring the precision and accuracy of the cutting.

[0022] 3. The motor drives the drive gear to rotate, which in turn causes the driven gear to rotate. The rotation of the driven gear causes the rotating tube to rotate, which in turn causes the C-shaped bracket and the placement board to rotate synchronously. This structural design makes it easy to rotate the PCB board after it is fixed for cutting on different sides.

[0023] 4. When the rotating tube rotates, the incomplete gear will rotate, which will drive the two rack plates to move away from each other. This will drive the push block to rotate the discharge plate through the corresponding push rod. When the incomplete gear is not in contact with the rack plate, the compressed spring will extend, thereby driving the push block away from the discharge plate. Through this structural design, the discharge plate can be shaken, causing the waste material remaining on the discharge plate to fall off.

It is also to be understood that the specific structural and functional details illustrated represent exemplary embodiments and that the specification is supported by a range of alternative embodiments.

[0037] Embodiment one

[0038] The embodiment of the present application discloses a bidirectional transmission integrated LED display screen. Referring to Figures 1 to 2 A bidirectional transmission integrated LED display screen, comprising a circuit layer 1 and a cover layer 2; the circuit layer 1 is distributed with metal pads 3 on both sides, and the circuit layer 1 is internally provided with metallized through holes 4, and the metallized through holes 4 can connect the metal pads 3 on both sides; the cover layer 2 is positioned and compressed with the circuit layer 1, and covers other parts except the metal pads 3.

[0039] Embodiment two

[0040] A manufacturing method of a bidirectional transmission integrated LED display screen, suitable for the bidirectional transmission integrated LED display screen, the manufacturing method of the bidirectional transmission integrated LED display screen comprises:

[0041] S1, preparing a circuit layer 1, forming a plurality of metal pads 3 on both sides of the circuit layer 1 through an etching process, and internally providing the circuit layer 1 with metallized through holes 4, the metallized through holes 4 penetrating both sides of the circuit layer 1 and connecting the metal pads 3 on both sides correspondingly;

[0042] S2, preparing a cover layer 2, the cover layer 2 being formed by hot pressing after mixing epoxy resin and glass fiber material;

[0043] S3, combining the cover layer 2 and the circuit layer 1 through a positioning and compression process, so that the cover layer 2 covers the area of the circuit layer 1 except the metal pads 3;

[0044] S4, six metallized through holes 4 are arranged on each metal pad 3, and are sequentially defined as No. 1 to No. 6 metallized through holes, and five functional areas are divided on the surface of the metal pad 3, and are sequentially No. 1 to No. 5 functional areas, wherein the No. 2 functional area is connected with the No. 2 metallized through hole and the No. 5 metallized through hole through an electroplating process;

[0045] S5, fixing a chip / I C on the packaged circuit layer 1, and realizing electrical connection through the metallized through holes 4, and finally using epoxy resin glue for insulation protection.

[0046] Specifically, as Figure 3As shown, the single unit has 6 metalized through holes connected with the metal pads 3 on the back, and 5 functional areas are built in, among which the No. 2 functional area is connected with the No. 2 and No. 5 metalized through holes, so that the No. 2 and No. 5 pins are connected within the package. The metalized through hole 4 is plugged with solder resist ink, which can effectively prevent the side pin from being exposed to light and metal oxidation. Except for the functional areas, other parts are covered by the cover layer 2.

[0047] As shown in the design diagram of the LED display circuit for bidirectional transmission, the VDD / GND is connected to the back of the PCB through the metalized through hole 4, and the power supply is provided through the back. Figure 4

[0048] The design circuit on the market connects the No. 2 pin and the No. 5 pin on the PCB, while the No. 2 / 5 pin in the lamp bead is a pin without any function, which causes the waste of PCB copper wire, and the function of the lamp bead package pin is not effectively utilized. The integrated LED for bidirectional transmission of the LED display screen connects the No. 2 pin and the No. 5 pin internally, so that the design of electronic assembly saves the copper foil, can transmit data at any end of the display screen, and supports the function of breakpoint continuation, so that the upstream and downstream can use one pin to achieve better display effect, greatly reduces the processing cost, and improves the utilization rate of the lamp bead / display screen.

[0049] Through the structure design, the electronic assembly of the lamp bead has greater thrust; the use of flat pins of the lamp bead makes the display screen have less side reflection and better display effect; the internal structure 2 / 5 of the lamp bead is connected, reducing the waste of copper wire; at the same time, one lamp bead can achieve the effect of bidirectional transmission; the production efficiency is higher, the waste of line switching, materials and labor is reduced, the reliability of the lamp bead is higher, and the heat dissipation is better.

[0050] Specifically, the pin definition is as follows: the No. 1 / 4 pin is an I / O pin (bidirectional transmission), the No. 2 / 5 pin is a main input pin (DIN), and the No. 3 / 6 pin is a power pin (VDD / GND);

[0051] In the PCB design, the external No. 2 / 5 pin connecting copper wire is cancelled, and the internal No. 2-5 pin conduction characteristic is utilized, so that the signal can be transmitted in any direction (forward or reverse);

[0052] When a lamp bead fails, the signal can bypass through the I / O pin of the adjacent lamp bead to ensure the continuity of the display picture.

[0053] Embodiment three

[0055] Specifically, in the cutting operation, all cutting operations need to be completed at one time, otherwise when one side of the PCB board is cut, the PCB board loses the limiting of the slot, so that the PCB board will be offset during processing, which may cause the cutting precision to decrease, and even damage the PCB board;

[0056] By placing the prepared PCB board on the top of placing plate 6, then pushing pressing disc 802 down by electric push rod one 801, so that pressing disc 802 contacts the PCB board, thereby completing the fixation of the PCB board, then cutting the two side edges of the PCB board by cutting assembly 9, then driving placing plate 6 to rotate by ninety degrees by drive assembly 7, so that the other two sides of the PCB board are aligned with cutting assembly 9, and the other side edges are cut by cutting assembly 9, through the structure design, the stable fixation of the PCB board is realized. This fixation mode can effectively prevent the PCB board from being offset during cutting, thereby ensuring the cutting precision and accuracy.

The placement plate 6 is inserted into the rotating pipe 700 through the sleeve, and when the rotating pipe 700 rotates, the placement plate 6 can be driven to rotate by the sleeve.

The middle part of the push rod 12 is fixedly provided with a pad, and the spring 15 is arranged between the vertical plate and the pad.

[0066] Specifically, considering that waste materials can be accumulated on the discharge plate 10, when the rotating tube 700 rotates, the incomplete gear 11 rotates, thereby driving the two rack plates 13 to move away from each other, and through the corresponding push rod 12, the push block 14 drives the discharge plate 10 to rotate, and when the incomplete gear 11 does not contact the rack plate 13, the compressed spring 15 expands, thereby driving the push block 14 away from the discharge plate 10, through the structure design, thereby the discharge plate 10 can be shaken, so that the waste materials remaining on the discharge plate 10 fall off.
