Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display manufacturing equipment technology, and in particular to a frame glue syringe cleaning device. Background Technology

[0002] like Figure 1 As shown, in the manufacturing of 2D / 3D LCD screens, frame adhesive 2 needs to be applied to the periphery of the display area of ​​the glass substrate 3 using a frame adhesive injector 1 to seal the liquid crystal. After the frame adhesive is applied, the frame adhesive injector 1 needs to be cleaned. The traditional cleaning method is to disassemble the injector 4, base 5, and nozzle 6 of the frame adhesive injector 1 and then place them in an ultrasonic cleaner for acetone-based agitation cleaning. Due to the high viscosity of the frame adhesive and the complex structure of the frame adhesive injector device, traditional disassembly and cleaning is complicated and easily leaves residual adhesive, leading to problems such as nozzle clogging, abnormal adhesive width, and adhesive breakage.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0021] like Figure 2 As shown, this utility model embodiment provides a frame glue syringe cleaning device, which includes at least a cleaning tank 15 and a circulation pump 9;

[0022] The conduit 8 is connected to the circulation pump 9; both ends of the conduit 8 are placed in the cleaning tank 15, one end of the conduit 8 is connected to the bottom valve of the circulation pump 9, and the other end of the conduit is connected to the frame rubber injector 1;

[0023] The control system 10 controls the circulating pump 9 to circulate the detergent 11 into the frame syringe 1 via the conduit 8 under preset pressure and time conditions.

[0024] The detergent 11 is selected from liquids that can dissolve the frame adhesive, such as acetone solution or isopropanol solution.
