Description

Technical Field

[0001] The utility model relates to the field of LED light boards, in particular to a flexible LED light board for paneling. Background Art

[0002] Liquid crystal displays are active matrix liquid crystal displays driven by thin film transistors. They primarily use electric current to stimulate liquid crystal molecules to generate dots, lines, and surfaces that form the screen in conjunction with backlight tubes. MiniLED liquid crystal displays typically use direct-lit light strips and light boards. The PCB aluminum substrate used in light boards is typically 0.8mm thick. To reduce costs, the thickness of the PCB aluminum substrate is reduced to 0.3mm. The 0.3mm aluminum substrate requires reflow soldering after SMT placement.

[0003] However, the thickness of the existing PCB aluminum substrate is relatively thin during reflow soldering. Under the action of its own gravity, the reflow soldering PCB aluminum substrate will warp, and the warping will cause poor soldering of the connector, affecting subsequent use. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a flexible LED light board for splicing to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a method for assembling an LED flexible light panel, comprising a pressing block, multiple groups of the pressing strips are fixed on one side of the pressing block, and multiple groups of magnetic blocks are arranged on one side of the pressing block, high-temperature magnets are installed on one side of three groups of the pressing strips, a screw column is arranged on one side of one group of the pressing strips, and screws are arranged inside the screw column.

[0006] By adopting the above technical solution, after the SMT patch is completed, a pressure block is added before reflow soldering. The pressure block is attached to the PCB aluminum substrate, one side of the pressure strip is close to the connector, and the magnet is attracted to the magnet at the bottom of the fixture base. This can prevent the PCB aluminum substrate from warping after reflow soldering, which may cause poor connector soldering.

[0007] The utility model is further configured such that a protrusion is fixed on one side of the pressing block.

[0008] By adopting the above technical solution, the provided protrusions can facilitate personnel to take the pressing block, thereby facilitating the installation of the pressing block.

[0009] The utility model is further configured such that the screw is an M5 hexagon socket head screw, and one end of the screw is provided with a protrusion.

[0010] By adopting the above technical solution, the protrusion on the end of the screw can facilitate personnel to operate the screw and turn the screw.

[0011] The present invention is further configured such that the S-level of the high-temperature magnet does not contact the pressure strip.

[0012] By adopting the above technical solution, the S-level high-temperature magnet can be easily matched with the external magnetic block, so that it can be adsorbed to achieve the purpose of fixation.

[0013] In summary, the present invention has the following beneficial effects:

[0014] The utility model is provided with a pressing block, a magnetic block, a pressure strip, a high-temperature magnet, a bump and a screw. After the SMT patch is completed, the pressing block is added before reflow soldering. The pressing block is attached to the PCB aluminum substrate, one side of the pressure strip is tightly attached to the connector, and the magnet is attracted to the magnet at the bottom of the fixture base. This can prevent the PCB aluminum substrate from warping after reflow soldering, which may cause poor connector welding. BRIEF DESCRIPTION OF THE DRAWINGS

A connector 9 is set at the bottom of the PCB aluminum substrate 8. The pressure strip 2 can press the connector 9, and the magnetic block 3 located on one side of the pressure strip 2 cooperates with the magnet at the bottom of the base to prevent the PCB aluminum substrate from warping after reflow soldering, which leads to poor connector welding. A screw column 5 is set on one side of a group of pressure strips 2, and a screw 7 is set inside the screw column 5.
