Problems solved by technology

Especially in the production of LCD TVs, high-viscosity superglue is used. The bonding of the backplane and the light bar requires the glue valve to complete dozens to more than one hundred glue points in about 10 seconds under the high-speed moving state. Now Gluing with a rubber valve in this high-speed state will cause serious problems such as glue leakage, stringing, too small glue spots, uneven glue spots, etc., and it cannot be used at all.

Embodiment Construction

[0013] Embodiments of the jet dispensing valve of the present invention will be described below in conjunction with the accompanying drawings.

[0014] exist figure 1 , 2 In 3, the spool A2 and the spool B8 are installed in the spool hole of the spool seat 1. The upper end of the spool B8 is pressed with a screw 20, the lower end of the spool B8 is pushed against the upper end of the spool A2, the lower part of the spool A2 is locked by the spool lock nut 3, and the spool lock nut 3 is screwed to the spool seat 1 superior. A needle 4 is sheathed on the mouth of the spool below the spool A2, and the needle 4 is pressed on the spool A2 by a needle cap 5 screwed on the spool A2. The connecting rod 11 is passed through the mounting hole of the stacking cylinder 13, and is connected to the valve core seat 1 by the threaded screw of the lower section, so that the stacking cylinder 13 is locked at a certain distance above the valve core seat 1. The cylinder rod of the stacking cy...

Abstract

The invention discloses an injection dispensing valve, a high-power double-cylinder superposition cylinder is taken as the power to drive a striker to rapidly move in a valve element plunger cavity soas to rapidly coat a glue, suck back and seal the glue at high speed, the requirements on the production of large glue points and fast efficient dispensing of large-screen liquid crystal display televisions and other electronic products are met, and the difficult problem of wiredrawing of the glue point is solved.

Description

[0001] Technical field [0002] The invention relates to a jet dispensing valve, in particular to a fast, high-efficiency, single-point dispensing valve. Background technique [0003] At present, the existing dispensing valves on the market are all low-speed, small glue dot dispensing valves applied to low-viscosity glue. However, in the production of many electronic products, the glue valve is required to be glued at high speed and with a large glue point. Especially in the production of LCD TVs, high-viscosity superglue is used. The bonding of the backplane and the light bar requires the glue valve to complete dozens to more than one hundred glue points in about 10 seconds under the high-speed moving state. Now If the glue valve is glued in this high-speed state, there will be serious problems such as glue leakage, stringing, too small glue spots, uneven glue spots, etc., and it cannot be used at all. Therefore, it is imperative to develop new fast, efficient, high-viscosi...
