Problems solved by technology

[0004] However, after the heating plate 20 is heated, the temperature of the support pins 30 will be higher than the ambient temperature, causing the alignment film solution on the surface of the substrate 40 that is in contact with the support pins 30 to be coated with an alignment film to volatilize quickly due to the high temperature. If it falls off, it will affect the quality of the alignment film, and will cause bright spots on the display, resulting in poor picture quality (mura) on the display.

Embodiment 1

[0039] Embodiment 1, the embodiment of the present invention provides an alignment film pre-curing equipment, such as figure 2 As shown, it includes a workbench 10, a heating plate 20 arranged under the workbench, and a plurality of support pins 30, the plurality of support pins are used to support the substrate 40, and the plurality of support pins 30 are arranged on the between the substrate 40 and the workbench 10 .

[0040] Wherein, the diameter of the tip of each of the plurality of support pins 30 is 0.5 mm, and each of the support pins 30 is made of PEEK or PI.

[0041]In this way, on the one hand, since PEEK or PI have the characteristics of high temperature resistance and low thermal conductivity, when each support pin 30 is made of PEEK or PI, the heat transferred to the corresponding place on the surface of the substrate 40 through the support pin 30 can be reduced. , on the other hand, since the diameter of the top of each support pin is only 0.5 mm, that is, the...

Embodiment 2

[0050] Embodiment 2, the embodiment of the present invention provides an alignment film pre-curing equipment, such as image 3 As shown, the pre-curing equipment includes a workbench 10, a heating plate 20 arranged below the workbench, and a plurality of support pins 30, the plurality of support pins are used to support the substrate 40, and the plurality of support pins 30 is disposed between the substrate 40 and the workbench 10 . Each support needle 30 includes a support needle 301 and a support column 302 , the support column 302 is located below the support needle 301 and is used to support the support needle 301 .

[0051] Wherein, the supporting needle 301 is conical, and the diameter of its tip is 0.5 mm; the supporting column 302 is cylindrical. The support needle 301 is made of PEEK or PI; the support column 302 is made of stainless steel SUS.

[0052] Like this, on the one hand, because PEEK or PI has the characteristics of high temperature resistance and low ther...

Embodiment 3

[0062] Embodiment three, such as Figure 6 As shown, the embodiment of the present invention provides an alignment film pre-curing equipment, the pre-curing equipment includes: a workbench 10, a heating plate 20 arranged under the workbench, and a plurality of support pins 30, the plurality of The support pins are used to support the substrate 40, and the plurality of support pins 30 are arranged between the substrate 40 and the workbench 10 and pass through the workbench 10 and the heating plate 20; further comprising: fixing the A fixing device 50 for supporting the needle, a lifting device 60 for driving the fixing device up and down, and an exhaust device 70 arranged around the working table 10 .

[0063] Wherein, each support needle 30 includes a support needle 301 and a support column 302 , the support column 302 is located below the support needle 301 and is used to support the support needle 301 . The fixing device 50 is located below the heating plate 20 and does not...

Abstract

The invention provides an alignment film pre-solidifying device and relates to the manufacturing field of liquid crystal displays. The alignment film pre-solidifying device does not affect quality of an alignment film and image quality of the display. The alignment film pre-solidifying device comprises a workbench and a heating plate arranged below the workbench and further comprises multiple supporting needles used for supporting a substrate. The supporting needles are arranged between the substrate and the workbench. The diameter of the top end of each of the supporting needles ranges from 0.5mm to 0.8mm. A part which at least comprises the top end of a supporting needle in each supporting needle is made of heat-resistant and thermally insulative materials. The alignment film pre-solidifying device is used for manufacturing liquid crystal displays.

Description

technical field [0001] The invention relates to the field of liquid crystal display manufacture, in particular to an alignment film pre-curing device. Background technique [0002] Alignment film pre-curing equipment After the alignment film is printed and before high-temperature curing, the substrate is heated at a medium and low temperature to dry the alignment film for pre-curing. At present, a hot plate heating method is generally used to pre-cure the substrate. [0003] For example, if figure 1 As shown, the current alignment film pre-curing equipment includes a workbench 10 , a heating plate 20 arranged under the workbench, and several support pins 30 arranged on the workbench for supporting the substrate 40 . Wherein, at present, the diameter of the tip of the support pin 30 is 1.8 mm. [0004] However, after the heating plate 20 is heated, the temperature of the support pins 30 will be higher than the ambient temperature, causing the alignment film solution on the...
