Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display equipment technology, specifically to a liquid crystal support structure that facilitates inspection of the solder joints of liquid crystal screen pins. Background Technology

[0002] In existing technologies, the following technical defects exist when assembling and soldering LCD screens onto circuit boards using brackets: 1) Inconsistent soldering times during the soldering process can easily lead to bridging between adjacent pins, and this bridging is difficult to observe visually, posing a quality hazard; 2) Traditional LCD brackets are installed flush with the circuit board, and the high temperature of the solder during soldering can easily deform the back of the bracket, further masking bridging faults and causing product malfunctions; 3) Existing bracket structures cannot visually inspect the solder condition on the circuit board after soldering, requiring additional tools or disassembly for inspection, which is inefficient and can damage the LCD bracket. Therefore, a new LCD bracket structure that facilitates the inspection of bridging between LCD screen pins is proposed. Summary of the Invention

[0003] The purpose of this invention is to solve the above problems by proposing a liquid crystal support structure that facilitates the inspection of the solder joints of the liquid crystal screen pins.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a liquid crystal support structure for facilitating the inspection of liquid crystal screen pin soldering, comprising a liquid crystal support body, characterized in that: a stepped structure is provided on the side of the liquid crystal support body connected to the circuit board, and a reserved gap for inspecting liquid crystal screen pin soldering is formed between the stepped structure liquid crystal support body and the circuit board; the liquid crystal support body is provided with through holes for liquid crystal screen pins to pass through, corresponding to the positions of soldering holes on the circuit board.

[0005] Preferably, the stepped structure is disposed at the position corresponding to the through hole on the liquid crystal bracket body.

[0006] Preferably, the top of the LCD bracket body is provided with an installation groove for embedding and installing the LCD screen, and the sides are provided with buckles for engaging with the circuit board and guide rods for positioning.

[0007] Preferably, the liquid crystal support body has several baffles above the through hole to guide the liquid crystal screen pins into the through hole.

[0008] Preferably, the LCD bracket body is made of high-temperature resistant insulating engineering plastic.

[0009] The beneficial effects of this utility model are as follows: By setting a stepped structure at the connection between the LCD bracket body and the circuit board, a reserved gap of 0.8-1mm is formed, which separates the soldering surface of the circuit board from the LCD bracket body. After soldering, the pin solder joints can be directly observed from the reserved gap on the side or front of the LCD bracket body. If there is bridging, it can be visually detected through the reserved gap without disassembly. At the same time, it also avoids the situation where the solder melts into the plastic and produces solder impurities, which would lead to product malfunction when there is no step.

[0018] Participation Figure 1-4As shown in this embodiment, a liquid crystal support structure for easy inspection of liquid crystal screen pin solder joints includes a liquid crystal support body 1. The structure is characterized by: a stepped structure 2 on the side of the liquid crystal support body 1 connected to the circuit board, the stepped structure 2 creating a reserved gap 3 between the liquid crystal support body 1 and the circuit board for inspecting liquid crystal screen pin solder joints; a through hole 4 on the liquid crystal support body 1 for the liquid crystal screen pins to pass through, corresponding to the position of the soldering hole on the circuit board; the reserved gap is 0.8-1mm; the reserved gap 3 is directly formed by the height of the stepped structure 2; by setting the stepped structure 2 at the connection between the liquid crystal support body 1 and the circuit board, forming a reserved gap 3 of 0.8-1mm, the soldering surface of the circuit board is separated from the liquid crystal support body 1. After soldering, the pin solder joints can be directly observed from the reserved gap 3 on the side or front of the liquid crystal support body 1. If solder joints exist, they can be visually detected through the reserved gap 3 without disassembly. This also avoids the situation where, without the stepped structure, the solder melts into the plastic, producing solder impurities that could lead to product malfunction.

[0019] In one embodiment, the stepped structure 2 is disposed at the position corresponding to the through hole 4 on the liquid crystal bracket body 1.

[0020] In one embodiment, the top of the LCD bracket body 1 is provided with an installation groove 5 for embedding and installing the LCD screen, and the sides are provided with buckles 6 for engaging with the circuit board and guide rods 7 for positioning; the LCD bracket body 1 is provided with several baffles 8 above the through hole 4 to guide the LCD screen pins into the through hole 4; the depth of the installation groove 5 matches the thickness of the LCD screen to ensure that it is flush with the edge after embedding; the baffles 8 form guide grooves between the baffles 8; during installation, the guide rods 7 on the LCD bracket body 1 are first inserted into the circuit board for positioning; then the LCD bracket body 1 is used for positioning. The clips 6 on the frame body 1 are snapped into the slots of the circuit board and fixedly connected to the circuit board. The LCD screen is embedded in the mounting slot 5. The pins of the LCD screen are guided into the through hole 4 through the guide groove formed by the baffle 8 and inserted into the soldering hole of the circuit board. Through the setting of the through hole 4, mounting slot 5, clips 6, and guide rod 7, the LCD screen, LCD frame body 1 and circuit board are quickly fixed and installed. At the same time, the cooperation of clips 6 and guide rod 7 ensures the structural stability during the soldering process and prevents pin misalignment due to vibration. The length of guide rod 7 is adapted to the thickness of the circuit board.

[0021] In one embodiment, the liquid crystal bracket body 1 is made of high-temperature resistant insulating engineering plastic; the high-temperature resistant engineering plastic material can withstand welding high temperature ≥260℃, avoiding the liquid crystal bracket body 1 from being deformed by heat; the insulating properties prevent the solder from melting with the plastic to produce solder impurities, eliminating the risk of short circuit.

[0022] In the process of using this utility model, firstly, the guide rods 7 on both sides of the LCD bracket body 1 are inserted into the circuit board for positioning. Then, the LCD bracket body 1 is pressed down so that the buckles 6 on both sides are engaged in the slots of the circuit board, thus fixing the LCD bracket body 1 to the circuit board. At this time, a reserved gap 3 of 0.8-1mm is formed between the stepped structure 2 on the LCD bracket body 1 and the circuit board. Then, the LCD screen is embedded and installed in the mounting slot 5 at the top of the LCD bracket body 1, so that the LCD screen pins are aligned with the through holes 4 on the bracket body. The pins pass through the through holes 4 and are inserted into the soldering holes of the circuit board. The baffle 8 above the through holes 4 ensures that the pins are inserted vertically. The assembly is flipped so that the circuit board faces upward for soldering.

[0023] After the soldering is completed, observe the circuit board solder joints within the reserved gap 3 from the side or front of the LCD bracket body 1. If the solder of adjacent solder joints is connected, it can be directly judged as a bridging solder joint and reworked in time.

[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
