Description

1237691 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a flat display panel detection device, in particular, a flat surface that can be used to detect different sizes and reduce the effects of jealousy caused by panel gravity. Display panel display device. v [Previous technology] Flat display panels have been widely used in CRTs and developed to be used in TV or computer screens. They have become the new-generation two-pack design. Therefore, the needs of various flat display n panels, including lcd : ,, and light panel are rapidly increasing. 々Before integrating the backlight module, driving circuit and other components into the display panel for flat panel display, the display panel needs to go through a test procedure first to check whether the panel is rich or rusty_ left on the panel, wire thief, panel on the panel Whether the gap is intact, whether there are cracks, etc., are separated by: Yi Xiao Liang Kou

Refer to Figure 1, which is a schematic side view of a conventional panel inspection device for an operator to visually inspect panel defects. U. The detection device has a flat plate-shaped platform for carrying a panel P on the upper half of the two-and-two measurement device. A plurality of support elements 110 are arranged on the platform 100 to support the fixed box. The lower surface and a plurality of positioning devices are used to abut against the sides of the panel P at the same time to clamp and position the panel P carried on the platform survey. Figure 2 is the Hi element of the conventional detection device shown in Figure i, and Figure 4 is the ^ element shown in Figure 3 = Yes. Do not ^ θ 'reveal the operation of positioning the panel by positioning devices such as 5 彡. As shown in Figure 2 to Figure 4, these positioning devices 200 are installed at. The peripheral edge of the top surface is used to simultaneously abut against the four sides of the panel ρ, and the position of the panel p is fixed above the platform 100 with 1237691 P. The cylinder contains-22G live rotation, which uses a twisted rod, and uses two solid wire sleeves 221a, 221b to set on the flat two fixed shaft sleeve Lang sleeve 221 sleeve ==== the spring 223 abuts.

Are arranged below the platform 10, and are spaced a predetermined distance apart from each other, and can be raised from below the platform 10 or Lowering, each of the fourth positioning devices 40a, 40b, 40c, and 40d respectively has a fourth positioning g 41 for abutting each side of a small panel P2, and a vertical conveying center for raising or lowering the A fourth positioning portion 41 for holding or removing the small panel 12 1237691 P2. The fourth positioning portion 41 includes a base 41, which is disposed on the vertical conveying portion 42, and a cylinder 411, which is horizontally disposed on the base. On the base 41, a first and a second positioner 413, 414, one of each of the positioners 413, 414 is pivotally disposed on a piston rod 412 moved by the cylinder 411, and other intermediate parts are pivoted Set on the base 4 =, a first and a second clamping roller 415, 416 are arranged on the other side of the first and first clamping units 413, 414 for abutting against the Corner of panel p2. In the present embodiment, the first and second clamping rollers 415 and 416 also have a polygonal cross section, so that the clamping rollers 415 and 416 are in contact with each other in the form of surface contact. The side of the panel P2, and the corners of the adjacent sides of the clamping rollers 415 and 416 also form an outer rounded corner. The seat 42 includes a cylinder 42 and is set upright on the platform 10 Below, a piston rod 421 is driven by the cylinder body 42 to push the base 420 to reciprocate in a vertical direction. Secondly, when the small panel P2 having a length L2 and a width W2 is placed on the platform Up, the control unit can sense the size of the p2, and control the four-position device 40a, 40b, 40c, and 40d of the 5th junior brother below the panel. Then, the fourth positioning devices 40a, 4 Each vertical of 〇b, 4〇c, 40d = ¾ section 42 pushes the first and second clamping rollers 4〗 5, 4 〖6 to the side of the small panel, and the cylinder 411 pushes the first The first and second clamping rollers 415, 416 Ξϊϊΐί nr each side to perform horizontal horizontal axis and horizontal warp i simultaneously to complete the small panel P2 After the test procedure, the fourth button 41 plate 1> 2, scale money yarn can be _ 帛 beer Jing "below Ii1G 'to return the fourth positioning portion 41 to the initial standby state.

Each ancient transport 43 includes a base 430 and is arranged on the wheel The M2 piston rod 421 'is used to carry the base 41. A guide = field between the base and the base,-red body 432 and-piston rod 433, used to push the base 410 forward and backward . In a practical application, the first prostitutes described in the first and second embodiments of the present invention can be placed on the same platform, so that panels with different lengths and widths can be clamped and positioned on this platform. .

From the system, in the detection device disclosed in the present invention, the platform 1G is composed of a reinforcing plate 11 made of a stone, a covering layer 12 and a layer 15 covering the outside of the reinforcing plate 11 as described in Section 12 As shown in the figure, the covering lining 12 is made of shells and buckets, and can be used for various additional components to be disposed thereon. The glue layer 15 is used to combine the reinforcing plate u and the covering pad 12 . The covering pad 12 includes a first pad 13 and a second pad 14, which respectively cover the upper half and the lower half of the reinforcing plate 11. The sides f of the two pads 13 and 14 respectively have -The extensions 13a, 14a are used to cover the lateral displacement of the reinforcing plate η.

By using the composition of stone and aluminum materials, the platform 10 can be prevented from being deformed and damaged by the gravity pressure of the panel during the operation, and different additional components can be easily set on the platform. FIG. 13 shows another type of the platform 10, which is the same as that of FIG. 12, and the difference is that the side of the reinforcing plate 11 further includes a plurality of embedded grooves 11a, and the extensions The inner side surfaces of the portions 13a, 14 & are respectively provided with the fitting flanges 13b, 14b of the engaging grooves 11a, respectively. ~ By using the fitting projections 13b, 14b to embed the fitting grooves 11a, f to strengthen the bonding force between the reinforcing plate 11 and the pads 13, 14 made of different materials, to improve the more stable combination; The shapes and positions of the fitting grooves and the front closing flanges can be changed differently according to requirements. Figure 14 also shows the change of the platform type, which is roughly the same as Figure 12 14 1237691-, the difference lies in the extensions] 7 1 Λ holes 13c, 14c, the side of the reinforcing plate is opened There are multiple = more = $ 复 | g through the corresponding screw hole 14c, so as to use the compound tooth holes 13c, 14c to set in this screw hole nb.
