Technical Field

The invention relates to the technical field of panel production, in particular to a water removing device for a panel.

Background

After entering an edge grinding machine, the liquid crystal display panel is subjected to edge grinding, and is cooled by cooling water while being ground, and then the grinding quality is detected by a Charge-coupled Device (CCD). Before testing, the water removing apparatus 10 shown in fig. 1-3 is usually used to remove water from the finished liquid crystal display panel, so as not to affect the accuracy of the testing result. As shown in fig. 1-3, the water removing apparatus 10 includes two rows of blowing

nozzles

11 and 12, which are respectively used for blowing air to remove water from the upper and lower surfaces of the liquid crystal display panel 20, but the blowing air flow provided by the two rows of blowing

nozzles

Detailed Description

The technical solutions of the exemplary embodiments provided in the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 4 to 6, the structure of the water removing apparatus according to an embodiment of the present invention is shown in three views, the water removing apparatus includes a fixed bracket 34, a first purging device 31 and a second purging device 32, the first purging device 31 and the second purging device 32 are disposed in a vertical direction in a horizontal extending direction of the fixed bracket 34, and the two

purging devices

31 and 32 are disposed at an interval such that the panel 40 can move therebetween to remove water. The first purge device 31 and the second purge device 32 are provided with at least one first gas flow passage 311 and at least one second gas flow passage 321, respectively, and the first gas flow passage 311 and the second gas flow passage 321 are arranged obliquely with respect to the vertical direction.

In the present embodiment, the first purge device 31 is configured to provide a first purge air flow to the first surface a of the panel 40, and the direction thereof is, as indicated by arrow a, arranged obliquely with respect to the first surface a of the panel 40. When removing water from the panel 40, the panel 40 and the first purge device 31 are moved relatively, for example, the first purge device 31 is stationary and the panel 40 is moved between the first purge device 31 and the second purge device 32 along a predetermined direction, which is a direction component of the first purge gas flow parallel to the first surface a, while the first purge gas flow is disposed obliquely with respect to the movement direction of the panel 40, so that the accumulated water on the first surface a can be pushed to the same direction, which is a direction component of the first purge gas flow parallel to the first surface a.

Referring again to FIGS. 4-6, a second purge device 32 is provided for providing a second purge flow to a second surface B opposite the first surface A, in a direction shown by arrow B, which is inclined relative to the second surface B. When removing water from the panel 40, the panel 40 and the second purging device 32 are moved relatively, for example, the second purging device 32 is stationary and the panel 40 is moved between the first purging device 31 and the second purging device 32 in a predetermined direction, in which case the second purging air flow is arranged obliquely with respect to the direction of movement of the panel 40, so that the accumulated water on the second surface B can be pushed in the same direction, which is the component of the second purging air flow parallel to the second surface B.

Compared with the prior art that accumulated water moves towards the periphery under the pushing of the vertical purging airflow, the inclined purging airflow provided by the water removing device provided by the embodiment of the invention enables the accumulated water to move along the same direction on the same surface of the panel 40, so that the water removing effect is strong, and the false detection rate of the grinding quality of the panel 40 caused by the accumulated water can be reduced.

In addition, the length direction of the projection of the gas outlet of the first gas flow channel 311 on the first surface a is obliquely arranged relative to the edge of the first surface a, so that the length direction of the purging area formed by the first purging gas flow on the first surface a is obliquely arranged relative to the edge of the first surface a, and the accumulated water at the edge of the panel 40 is pushed to the same direction; the gas outlets of the second gas flow passages 321 are obliquely arranged with respect to the edge of the second surface B in the length direction of the projection of the second surface B, so that the length direction of the purge region formed on the second surface B by the second purge gas flow is obliquely arranged with respect to the edge of the second surface B, thereby pushing the accumulated water at the edge of the panel 40 in the same direction. This design may further enhance the water removal effect on the edges of the panel 40.

The water removing apparatus of the embodiment of the present invention can be used for removing water from a panel 40 including, but not limited to, a liquid crystal display panel, and in view of the fact that the liquid crystal display panel is a multi-Substrate structure, specifically, the panel 40 includes a first Substrate 40 and a second Substrate 42, one of which is an Array Substrate (TFT Substrate or Thin Film Transistor Substrate), and the other is a Color Filter Substrate (CF Substrate or Color Filter Substrate), and with continuing reference to fig. 4 to 6, the water removing apparatus of the embodiment of the present invention may further include a third purging apparatus 33 disposed adjacent to a side of the fixing support 34 facing the panel 40. The third purging device 33 is configured to provide a third purging air flow (as indicated by arrow c) to the joint position of the first substrate 41 and the second substrate 42 of the panel 40, and preferably, the third purging air flow is disposed obliquely with respect to the joint position, i.e., the third purging air flow is disposed obliquely with respect to the joint position, and can also push the accumulated water at the joint position to the same direction, so as to achieve a strong water removal effect.

It should be understood that the above-mentioned embodiments are only examples of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow changes made by using the contents of the present specification and the drawings, such as the combination of technical features between the embodiments, or the direct or indirect application to other related technical fields, are also included in the scope of the present invention.
