The rails 21a and two or more blocks 21b are mounted on the top of the mounting plate 11 attached to the rectangular table 10 having wheels 12 attached to respective corners of the lower side and having a storage space and an electric main box therein. The LM guide 21 is composed of a plurality of spaced apart at a predetermined interval so that the block 21b is fixed to the fixed plate 22, LM guide 21 slide device equipped with a buffer port 23 on one end of the longitudinal direction ( 20 is formed of the lower slide portion 2a and the upper slide portion 2b formed by forming the upper and lower portions to cross each other, and the mounting protrusions 51 and the fixing protrusions 52 are formed on the mounting holes 53 at an upper portion thereof. In the inspection device for visual inspection of LCD (liquid crystal display-liquid crystal display) equipped with the mounting plate 50 mounted to enable the visual inspection of the surface of the LCD glass (L);

The fixing ball 32a formed in the fixing hole 32 is inserted into the seating hole 31a of the seating block 31 fixed to the center of the fixing plate 22 of the upper slide portion 2b, the seating plate (50) Friction surface of the engaging piece 33 in a state of being inserted into the rotary groove (34a) of the hemisphere of the rotary block 34 mounted to the lower portion of the rotary plate 41 mounted to the bottom with a plurality of fixing pins (42) 33a) is mounted on the rotary block 34 with a plurality of springs 35 and bolts 36 so as to contact the lower outer surface of the fixed ball 32a to configure the rotary device 30.

In the improved structure of the inspection apparatus of the present invention, which is configured as the rotary device 30 configured as described above, the configuration and operation of the inspection apparatus when visually inspecting the surface of the LCD glass L are as follows.

First, as shown in FIG. 3, the LCD glass L to be visually inspected is directly contacted with the mounting hole 53 formed at a predetermined interval in accordance with the specifications of the LCD glass L on the seating plate 50. After mounting the mounting projections 51 to be in uniform contact with the contact surface of the LCD glass (L) and the fixing projections 52 for contacting the side of the LCD glass (L) to prevent separation from the mounting plate (50) The LCD glass (L) is mounted so that the surface of the LCD glass (L) to be checked using the rotating device (70) and the slide device (20) safely.

As described above, by allowing the position of the seating protrusion 51 and the fixing protrusion 52 to be changed in accordance with the specifications of the LCD glass L, a single inspection device is applied to the LCD glass L of various specifications for visual inspection. In the modern society of the multi-volume small-volume production system, which can be changed in various ways, it is possible to reduce the production cost of inspection equipment and reduce the burden on maintenance.

As shown in Figs. 4 and 5, the slide device 20 constituted by the LM guide 21 on the upper portion of the conventional table 10 is composed of the lower slide portion 2a and the upper slide portion 2b, respectively. The buffer port 23 is provided on the fixing plate 22 so as to be positioned at both ends of the longitudinal direction of the LM guide (L) while allowing the inspector to easily transfer it in a desired direction with a small force as necessary. Even if the fixed plate 22 of the slide device 20 to be mounted and conveyed is subjected to the buffering action of the buffer port 23 to prevent the block 21b from being separated from the rail 21a, the fixed plate 22 is conveyed at a high speed. By minimizing the impact at the time of contact, it minimizes the impact, shaking and noise of the entire inspection device so that the inspection device can be used safely and quietly for a long time.

In addition, as shown in Figure 6 to form a fixing ball (32a) on the upper part of the fixing device 32 to be inserted into the seating hole (31a) of the seating block 31, the coupling piece 33 is bolted to the rotary block (34) By attaching to (36) so that the friction surface (33a) is in contact with the outer surface of the lower portion of the fixed ball (32a) by the elasticity of the spring (35).

The rotary block 34 is rotated by the rotary groove 34a around the fixing ball 32a of the fastener 32 mounted by the mounting block 31 at the center of the fixing plate 22 of the upper slide 2b. It is possible to rotate as well as front, rear, left and right, and the rotary motion and rotational device of the visual inspection device for LCD glass visual application device filed by the applicant of January 5, 2002 (Application No. 20-2002-0000319). The angular motion was to be able to do what was done at the same time.

That is, as shown in the detailed configuration of FIG. 6, the rotary groove 34a of the rotary block 34 is seated on the entire upper outer surface of the fixing ball 32a of the fixing tool 32, and then the coupling piece 33 is bolted. And the compression state of the spring 35 is deformed according to the tightening state of the bolt 36, and the friction surface 33a of the coupling piece 33 is formed on the outer surface of the fixing ball 32a due to the repulsive force. The contact is in close contact with the configuration to facilitate the assembly as well as to prevent the separation of the rotary block 34 mounted on the fixed ball (32a) after the completion of assembly.

Therefore, when the plurality of bolts 36 are loosely tightened, the repulsive force of the spring 35 is small, so that the friction surface 33a of the coupling piece 33 and the rotation groove 34a of the rotary block 34 come into close contact with the fixing ball 32a. As the force becomes weaker, the frictional force of each other is smaller, so that the rotation block 34 is rotated more naturally and the rotation block 34 is not fixed and is moved to the center by one's own weight, and the bolt 36 is deeply moved. When tightened, the repulsive force of the spring 35 increases, so that the friction surface 33a and the rotating groove 34a are in close contact with the fixing ball 32a, so that the frictional force increases, so that the rotation block 34 is not only difficult to rotate but also the frictional force. The rotating block 34 may be prevented from moving.

At this time, even if the bolt 36 is properly adjusted, the contact pressure can be finely adjusted by the elasticity of the spring 35, and it is not only easy to adjust the initial friction pressure, but also easy to change the friction pressure due to wear due to long-term use. As an adjustable structure, it can prevent problems such as the inclination due to the weight described above and the inspector's inability to move easily, and can prevent the causes of safety accidents and failures in advance while having a simple structure. will be.

By configuring the rotary device 30 between the slide device 20 and the seating plate 50 as described above, the plane can be moved more simply and horizontally, including front, rear, left, and right, and tilted in all directions while allowing 360 ° rotation. By mounting the glass (L), the surface to be checked with the naked eye can be moved faster to the position that the inspector can see the nearest and comfortable.

As described above, by configuring the respective devices such as the slide device 20 and the rotating device 30 to form an inspection device, the LCD glass L is mounted to visually inspect the surface. The examiner applies the external force directly to the front, rear, left and right direction without driving the device, and inclines and rotates the surface of the LCD glass L so that the examiner can check it in a comfortable posture in consideration of the reflection of light from the light. While inspecting the surface of the LCD glass to be inspected at the closest and most comfortable, it is often transported so that it can be seen accurately.

As described in detail above, the improved structure of the visual inspection apparatus for the liquid crystal display glass of the present invention comprises only a rotating device between the slide device and the seating plate, thereby reducing the manufacturing cost and the management cost, thereby reducing the financial burden as well as the mechanical structure. It can be operated only by manual operation based on the principle, so that the angle transfer can be finely and precisely, so that the part to be inspected can be inspected at a more comfortable angle. It is designed to improve the quality and productivity of LCD glass production by inspecting it more quickly, safely, accurately and comfortably.
