Problems solved by technology
[0003] Since the UV curing glue nozzle needs to be replaced regularly, the glue head is fixed in the coating mechanism by thread. The traditional way is to use a live-end wrench to rotate the screw to fix it. Since the strength and tightness of each fixing cannot be quantified, it may cause UV curing glue nozzle. Relative to the height change of the array substrate, it is very likely to cause the breakage of the UV curing glue nozzle (made of plastic) and cause unnecessary downtime

Embodiment Construction
[0032] In order to improve the accuracy of spray head installation and further improve the coating effect of ultraviolet curable glue, the embodiment of the present invention provides a spray head installation device. The elastic clamping structure on the turntable limits the relative rotation between the two. When the small turntable bears the set torque, the elastic clamping structure deforms, and the small turntable rotates relative to the large turntable, thus ensuring that the force of the installed nozzle remains set. The value improves the installation accuracy of the nozzle, thereby improving the coating effect of the photoresist. In order to make the object, technical solution and advantages of the present invention clearer, the following non-limiting examples are taken as examples to further describe the present invention in detail.

The invention relates to the field of display devices and discloses a nozzle mounting device comprising a large rotary disc and a small rotary disc. An accommodating groove is coaxially formed in the large rotary disc, and the side of the accommodating groove is provided with clamping grooves. The small rotary disc is located in the accommodating groove, is capable of rotating corresponding to the large rotary disc and is provided with an inserting groove used for mounting a nozzle in a clamped manner and an elastic clamping structure matching with the clamping grooves to lock the small rotary disc. When the torque borne by the small rotary disc exceeds a preset value, the elastic clamping structure deforms in an elastic manner, and the small rotary disc rotates corresponding to the large rotary disc. According to the technical scheme, the torque borne by the small rotary disc is limited through the elastic clamping structure, when the small rotary disc reaches the preset torque, the nozzle is mounted in place, the elastic clamping structure deforms in the elastic manner, and the small rotary disc rotates corresponding to the large rotary disc accordingly, the force applied to the nozzle is unloaded, the mounting accuracy of the nozzle is improved, and the effect of coating ultraviolet curing adhesive is further improved.
Description
technical field [0001] The invention relates to the field of display device manufacture, in particular to a nozzle installation device. Background technique [0002] At present, in the TFT-LCD production process, the OLB ultraviolet curing adhesive coating process uses a nozzle to spray the ultraviolet curing adhesive. This process needs to control the height, speed and flow of the nozzle from the array substrate. The accuracy and flow rate of the spraying are related to the nozzle. height is directly related. [0003] Since the UV curing glue nozzle needs to be replaced regularly, the glue head is fixed in the coating mechanism by thread. The traditional way is to use a live-end wrench to rotate the screw to fix it. Since the strength and tightness of each fixing cannot be quantified, it may cause UV curing glue nozzle. Relative to the height change of the array substrate, it is very likely to cause the breakage of the UV curing glue nozzle (made of plastic) and cause unne...
