Description

Technical Field

[0001] This utility model specifically relates to a corner-splitting device for an LCD screen. Background Technology

[0002] In the structural design of LCD monitors, the screen edges are cut into bevels instead of right angles. This process is quite common in industrial design and has the following main advantages: improved structural strength, as right angle edges are prone to stress concentration, while bevels can disperse pressure and reduce the risk of edge breakage during transportation or assembly; optimized installation compatibility, as beveled edges are easier to embed into the device casing, reducing assembly interference problems caused by tolerances; and enhanced visual aesthetics, as beveled edges can create a "narrow bezel" visual effect, improving the perceived screen-to-body ratio.

[0003] Existing methods for processing the edges of LCD screens often rely on manual experience to break the four corners of the screen to remove right angles. This is slow and lacks proper positioning of the screen during the breaking process, leading to human error and affecting the processing results. Therefore, we propose a corner-breaking device for LCD screens. Utility Model Content

[0004] The purpose of this invention is to provide a corner-splitting device for an LCD screen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corner-splitting device for an LCD screen, comprising:

[0006] A placement platform, wherein a positioning plate for positioning the LCD screen is provided at one end of the upper surface of the placement platform;

[0007] A fracturing opening is formed at the other end of the upper surface of the placement platform;

[0008] The pressure block assembly is rotatably mounted inside the fracturing opening to fracture the corner of the positioned LCD screen.

[0009] A collection box is located inside the placement platform and communicates with the inside of the fracturing port. An inlet and outlet for the collection box are provided on one side wall of the placement platform.

[0010] Preferably, the pressure block assembly includes a plate, a pressure block, and a rotating shaft. The plate is rotatably mounted inside the fracturing opening via the rotating shaft on the side wall, and the upper surface of the placement platform has a limiting plate that restricts the rotating shaft from coming out of the fracturing opening. A pressure block is fixed to one end of the lower surface of the plate.

[0011] Preferably, the pressure block is symmetrically arranged in two places along the center of the long side of the plate.

[0012] Preferably, the positioning plate is provided in two locations, and the two positioning plates are distributed at right angles.

[0013] Preferably, a handle is fixed to one end of the collection box.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a corner-splitting device for an LCD screen, comprising:

[0024] Placement platform 1, with a positioning plate 2 for positioning the LCD screen at one end of the upper surface of placement platform 1;

[0025] This facilitates the positioning of the placed LCD screen, enabling accurate subsequent cracking of the two right-angled edges of the LCD screen;

[0026] Fracturing opening 7 is located at the other end of the upper surface of placement platform 1;

[0027] The pressure block assembly 8 is rotatably installed inside the fracturing port 7 to fracture the corner of the positioned LCD screen.

[0028] The pressure block assembly 8 can be rotated manually by the rear motor, so that it contacts and presses down on the LCD screen to form a cleft.

[0029] The collection box 4 is located inside the placement platform 1 and is connected to the inside of the fracturing port 7. An inlet and outlet 3 for the collection box 4 to enter and exit is provided on one side wall of the placement platform 1.

[0030] This facilitates the collection of fractured fragments for later periodic cleanup.

[0031] In this embodiment, preferably, the pressure block assembly 8 includes a plate 81, a pressure block 82 and a rotating shaft 83. The plate 81 is rotatably mounted inside the fracturing opening 7 via the rotating shaft 83 on the side wall, and the upper surface of the placement platform 1 has a limiting plate that restricts the rotating shaft 83 from coming out of the fracturing opening 7. The pressure block 82 is fixed at one end of the lower surface of the plate 81.

[0032] The plate 81 can be rotated to adjust the proximity or distance between the pressure block 82 and the LCD screen. When it is close, the right-angle edge of the LCD screen is cracked. When it is far away, another LCD screen can be replaced for corner cracking.

[0033] In this embodiment, preferably, the pressure block 82 is symmetrically arranged in two places along the center of the long side of the plate 81;

[0034] This allows for simultaneous cracking of both right-angled edges of the LCD screen.

[0035] In this embodiment, preferably, there are two positioning plates 2, which are distributed at right angles.

[0036] This facilitates better positioning of the LCD screen.

[0037] In this embodiment, preferably, a handle 5 is fixed to one end of the collection box 4;

[0038] The collection box 4 is easy to pull out from the inside of the placement platform 1, or push into the inside of the placement platform 1 to collect the crushed LCD screen fragments.

[0039] In this embodiment, preferably, a first magnet 9 is embedded in one end of the inner side of the collection box 4, and a second magnet is fixed on the inner side of the placement platform 1 corresponding to the first magnet 9.

[0040] This facilitates the movement of the collection box 4 into place when it is pushed into the inner side of the placement platform 1, and prevents the collection box 4 from accidentally sliding out from the inner side of the placement platform 1 through the magnetic attraction between the first magnet 9 and the second magnet.

[0041] In this embodiment, preferably, the placement platform 1 is rectangular, and a through hole is provided in the middle of the upper surface of the placement platform 1, so as to facilitate observation of the quantity of items collected inside the collection box 4 through the through hole for cleaning.

[0042] The working principle and usage process of this utility model are as follows: After the LCD screen is cut, it is placed on the placement table 1. The LCD screen is positioned by the positioning plate 2. Then, the pressure block assembly 8 is manually rotated and moved closer to the LCD screen. The two pressure blocks 82 simultaneously squeeze the two corners of the LCD screen, thereby cracking the right angles on both sides of the LCD screen. The right angle fragments fall into the inside of the collection box 4 under the action of gravity for collection. The collection box 4 can be pulled out from the inside of the placement table 1 periodically for cleaning. By treating the right angles of the LCD screen edges to form chamfers, it is beneficial to reduce micro-cracks on the edges of the LCD screen, improve the yield, and avoid damage to the light guide plate or reflective film by the right angle prism.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
