Problems solved by technology

During the use of the spring clamp, the following problems were found: 1. The clamping force of the spring is large, which is easy to cause damage to the edge of the TFT-LCD liquid crystal glass, affecting the output and quality; 2. After the spring clamp is used for a long time, the spring and the rotation The wear and tear of the components leads to changes in the clamping force, and the clamping force is uncontrollable, resulting in the clamping force of some parts of some TFT-LCD liquid crystal glass not up to standard, and the maintenance and repair of the spring clamp is also more troublesome

Embodiment 1

[0034] see Figure 1 to Figure 8 , in the structural configuration of the glass substrate holder mounting fixture of the present invention, including the following structural features:

[0035] Substrate frame 1 : as a base frame structure for carrying the vertical clamp 2 , the lateral clamp 3 and the lower clamp 4 , it is convenient for the placement and positioning of the glass substrate 5 .

[0036] The first through hole 101: the substrate holder 1 has a plurality of first through holes 101, the vertical clamp 2 and the horizontal clamp 3 are installed at the corresponding positions of the first through holes 101, and the first through holes 101 are connected to each other. The guide sleeve 8 facilitates the direct passage of the lower guide rod 204 and its related structures. The diameter of the first through hole 101 is the same as that of the upper lumen 801 of the guide sleeve 8 .

[0037] Vertical clamp 2 : including upper limit plate 201 , splint 203 , hand-held st...

Embodiment 2

[0065] The invention relates to a method for using a TFT-LCD glass substrate frame mounting fixture, which specifically includes the following steps:

[0066] (1) Before performing all operations, first install the guide sleeve 8 at each position at the position of the inner threaded ring body 7 on the lower side of the substrate frame 1. Pay attention to the inner threaded ring body 7 when fixing the installation. 7 Align the first through holes 101 .

[0067] (ii) first align the lower fixture 4 on one side of the glass substrate 5, place the glass substrate 5 smoothly on the substrate frame 1, and make the glass substrate 5 be positioned between the first through holes 101 of the installed positions of the two lateral fixtures 3; between.

[0068] (iii) Using the hand-held structure 202, insert the magnetic steel disks 205 of the vertical clamp 2 and the horizontal clamp 3 into the lower lumen 802 of the guide sleeve 8, while the plastic sleeve 206 also falls into the uppe...

Embodiment 3

[0073] In the present invention, except for the magnetic steel plate 205, other structures can be made of low-cost non-magnetic materials, for example, the upper limit plate 201, the splint 203, the hand-held structure 202, and the lower guide rod 204 can be made of PVC plastic injection molding It is integrally formed, and the magnetic steel plate 205 can be fixed under the lower guide rod 204 by using super glue. A threaded groove can also be provided in the middle position of the magnetic steel plate 205 , the lower end of the lower guide rod 204 is provided with threads, and the magnetic steel plate 205 is installed on the lower end of the lower guide rod 204 by screwing.

[0074] In addition, the magnet mounting sleeve 9 and the guide sleeve 8 can also be made of the above-mentioned PVC plastic material, which can not only reduce the cost, but also avoid affecting the magnetic attraction between the magnet block 10 and the magnetic attraction steel plate 205 .

Abstract

The invention discloses a TFT-LCD (Thin Film Transistor-Liquid Crystal Display) glass substrate frame mounting clamp and a using method, and relates to the field of TFT-LCD glass processing equipment. A guide sleeve is installed at the position of an inner threaded ring body in a threaded mode. Each of the vertical clamp and the transverse clamp comprises an upper limiting disc, the annular side of the upper limiting disc is connected with a clamping plate, the lower side face of the upper limiting disc is connected with a lower guide rod, the lower side end of the lower guide rod is connected with a magnetic steel disc inserted into the lower pipe cavity, and the lower guide rod is sleeved with a spring located between the plastic sleeve disc and the upper limiting disc; a magnet installation sleeve is installed at the inner thread position of the lower pipe cavity in a threaded mode, and a magnet is embedded in the inner side of the magnet installation sleeve. When the clamping plates of the clamp are used for clamping the glass substrate, the instantaneous clamping pressure difference of the clamping points is small, surrounding type low-pressure-difference clamping adjustment is formed, and the glass substrate is prevented from being extruded by the pressure difference; and the clamping force of the clamping plates can be adjusted according to the actual clamping force requirement.

Description

technical field [0001] The invention relates to the field of TFT-LCD liquid crystal glass processing equipment, in particular to a TFT-LCD glass substrate frame mounting fixture and a use method. Background technique [0002] When designing and producing TFT-LCD liquid crystal glass, in the past, when clamping and fixing TFT-LCD liquid crystal glass, the substrate holder trolley basically used a spring clamp. During the use of the spring clamp, the following problems were found: 1. The clamping force of the spring is large, which is easy to cause damage to the edge of the TFT-LCD liquid crystal glass, affecting the output and quality; 2. After the spring clamp is used for a long time, the spring and rotation The wear of the components leads to changes in the clamping force, and the clamping force is uncontrollable, resulting in the substandard clamping force of some parts of the TFT-LCD liquid crystal glass, and the maintenance and repair of the spring clamp is also more tro...
