Embodiment Construction

[0032] As mentioned in the background technology section, the frame sealant spraying device in the prior art has relatively large limitations when coating arc-shaped frame sealants. The inventor found that this is because the sealing glue spraying device in the prior art can only coat in the X direction or the Y direction, but cannot complete the arc coating with a certain inner diameter, which leads to the sealing glue in the prior art The spraying device has great limitations when applying arc-shaped sealant.

[0033] In view of this, an embodiment of the present invention provides a spraying device for display panels, including: a moving rod, a radius rod, a fixed rod and a nozzle, wherein,

[0034] The moving rod is located in a plane perpendicular to the fixed rod and connected to the fixed rod;

[0035] The radius rod is located in a plane perpendicular to the fixed rod, one end of which is connected to the fixed rod, and the other end is connected to the nozzle, and th...

Abstract

The embodiment of the invention provides a spraying device and method for a display panel. The spraying device comprises a moving rod, a radius rod, a fixed rod and a nozzle; the moving rod is positioned in a plane which is vertical to the fixed rod and is connected with the fixed rod; the radius rod is positioned in the plane vertical to the fixed rod; one end of the radius rod is connected with the fixed rod, and while the other end of the radius rod is connected with the nozzle; the radius rod drives the nozzle to rotate about the fixed rod. According to the spraying device, the radius rod can be rotated to drive the nozzle to rotate like an arc line about the fixed rod, in order to realize the coating of arc-shaped frame sealing glue; therefore, the limitation on the frame sealing glue spraying device in the coating of the arc-shaped frame sealing glue under the prior art can be overcome.

Description

technical field [0001] The invention relates to the field of coating technology, in particular to a spray coating device and a spray coating method for a display panel. Background technique [0002] At present, the specific steps of the liquid crystal screen box forming process are as follows: first, use a sealant spraying device to coat the frame sealant around one substrate; then, use the drop injection method to drop the liquid crystal in the center of another substrate; after that, Vacuum lamination of the two substrates, that is, the box alignment process; finally, the curing of the frame sealant is performed to complete the box forming process. However, the frame sealant spraying device in the prior art is only set for square frame sealants, and has relatively large limitations when coating arc-shaped frame sealants. Contents of the invention [0003] In order to solve the above technical problems, an embodiment of the present invention provides a spraying device an...
