Description

Integrated liquid crystal display panel loading CST {a loading CST for a unity liguid crystal display panel}

The present invention relates to an integrated liquid crystal display (abbreviated as 'LCD') panel loading CST. More specifically, it is an essential liquid crystal display panel loading CST that moves and copes with each process panel during LCD panel production at a liquid crystal display panel manufacturing plant. Components are fastened by bolts and have many joints to eliminate problems such as contamination and weakened strength due to infiltration of foreign substances, minimize the defective rate of products and provide high quality products. It relates to a liquid crystal display panel loading CST.

Split liquid crystal display (LCD) panel CSTs generate many joints with fine gaps when assembled between a plurality of individual components. In other words, the upper frame and the lower frame are assembled with a plurality of square bars (bars) with many joints, etc., which has many advantages in work efficiency and productivity. However, due to the occurrence of many joints and gaps, the contaminants come into contact with the product due to the infiltration of foreign matters and the high deposition of chemicals, which causes defects in production, namely the liquid crystal display panel is a very precise and sensitive product. Considerable attention is required because fine foreign matter may be defective even if contacted.

In this invention, in order to reduce the above-mentioned problems, the upper and lower frames are connected to each other by a plurality of square bars (ber) in order to reduce the joints having many gaps in the construction of a plurality of parts fastened together. It is a method that is made by CNC cutting processing of one plate that does not have a connection part, not a fastening method, so that it does not have any connection part in the upper and lower frames, thereby suppressing the infiltration of dirt and having a considerable structural strength. The main focus is on the technical task.

1 is a view showing a preferred embodiment of the present invention, it will be described in detail the configuration and operation of the present invention.

CST (cassette) of the present invention has a cross-section at the top and bottom surface in the shape of a substantially rectangular box, and the frame (1a) in which several frames (1a, 2a) having a BAR shape are formed in plan view. , 2a) is formed of two horizontal and two vertical meshes, respectively, the upper and lower frames (1,2) is CNC-cutting the remaining portion except the skeleton (1a, 2a) is the entire skeleton ( 1,2a) is constructed integrally with no joints at all. This can have the effect of a significant increase in strength compared to the split type compared to the same structure.

In addition, the upper and lower frames (1, 2) at both ends of the side frame (3) having a CNC machine shape processing part for the weight or flow of each liquid and equipment correspond to each assembly, which is composed of upper and lower frames (1, 2) and the support frame (5), the guide shaft (4), etc., to which the side plate (10) is fastened, are fastened here to support most loads, and thus are formed in a unitary structure.

The parts connected to the upper and lower frames 1 and 2 are assembled using fastening means 20 such as a range of bolts in an engagement configuration after forming a jaw as shown in the drawing, which is a convenient advantage in disassembly and maintenance. To have.

In addition, the upper and lower frames 1 and 2 have two guide shafts 4 at one side before and after the inner surface thereof, and both ends thereof are fixed to the side frames 3 and 3a in the horizontal direction. In the longitudinal direction, four side plate supporting frames (6) in the longitudinal direction are configured to maintain appropriate intervals corresponding to each of the upper and lower sides, which is formed on the guide shaft (4) and the model change bracket (7). It is composed by tightening.

The side plate (10) formed with a plurality of locking edges (11) on the side of two side plate support frame (6) configured to correspond to each of the upper and lower ones, each of the four four per frame of the support frame, such as bolts, etc. The fastening means 20 to be configured to be fastened in a straight line.

At this time, when dividing the CST (A), the side plate (10) is configured so that the two edges (10a) facing each other one by one left, right so that the liquid crystal display panel (P) can be easily loaded. It is.

In the above configuration, the front side is in an open state, and at the rear side, two stopper pins 8 are configured to prevent the panel from escaping to the rear of the CST (A) and the panel P when the liquid crystal display panel P is loaded. The upper and lower frames (1,2) between the left and right sides of the support pins (9) is composed of eight vertically connected to the upper frame (1) and the lower frame (2). This supports the load in the vertical direction and serves to prevent structural distortion of the CST (A).

According to the present invention having the above configuration, the liquid crystal display panel is inserted into a loading space in which a side plate 10 is faced at the front of the CST (A), and the stacked panels are panels of different models due to model changes. At this time, the side plate support frame (6) to which the SIDE PLATE (10) is fixed is moved on the guide shaft (4) by the bolt tightening and loosening operation of the model change bracket (7) to the size of the model It can be compatible with each model by making it correspond to.

In performing this, the side plate supporting frame 6 is moved on the guide shaft 4 so as to be firmly fixed by the crimping method by the fastening means 20 such as the bracket 7 and the bolt. This has the advantages of simple structure and operation and low cost of processing.

The integrated display panel loading CST of the present invention having the same structure and operation as described in detail above is structurally simple, and in particular, there is no seam at the top and the frame, so that problems such as dirt retention are naturally solved and thus high quality products. Many effects can be obtained in production, and the strength is considerably increased compared to the split type compared to the same structure.

Due to the loss of the material due to the processing of the same structure compared to the same structure (loss) due to some disadvantages such as material loss and processing cost increase and the lack of shock absorption, it is a devised design that can be effectively used under particularly bad conditions.
