A high-precision seamless dripping CNC glue filling device

Abstract

The invention discloses a high-precision left-drop-free numerical control glue filling device. The high-precision left-drop-free numerical control glue filling device consists of a conveying belt (1), an insulation rotary plate (2), buffer chambers (3), pistons (4), unidirectional valves (5), flow rate regulating valves (6), weighing sensors (7), weighing sensor control panels (8), filling bottle control rods (9) as well as fixing guide pipes (10); the unidirectional valves (5) are connected to inlets at one sides of the buffer chambers (3); the lower ends of the buffer chambers (3) are connected with the flow rate regulating valves (6); the upper parts of the buffer chambers (3) are provided with the pistons (4); the weighing sensors (7) are fixed on the weighing sensor control panels (8); the conveying belt (1) and the weighing sensors (7) are arranged in adjacency. The glue filling precision can be controlled accurately through controlling the weighing precision; the influence to the glue filling precision by air bubble generation randomness in filling glue is eliminated completely; the glue filling precision is improved effectively.

Description

technical field [0001] The invention relates to a numerically controlled glue filling device, specifically to overcome the influence of the randomness of bubbles generated during glue filling on the glue filling precision, and at the same time solve the drop phenomenon caused by the viscosity of the glue. glue device. Background technique [0002] There are many types of glue filling machines, including automatic glue filling machines, semi-automatic glue filling machines, digital display glue filling machines and quantitative glue filling machines. Domestically produced glue filling machines generally have problems such as glue valve dripping, unstable flow rate, and bubbles in the glue. The reason is that the glue is viscous, so after the valve is closed, the glue head often continues to drip continuously; in the prior art, the volume of the glue is controlled to realize quantitative filling, but because the air pressure of the glue stored is unstable, thus Bubbles are r...

AI Technical Summary

Problems solved by technology

The reason is that the glue is viscous, so after the valve is closed, the glue head often continues to drip continuously; in the prior art, the volume of the glue is controlled to realize quantitative filling, but because the air pressure of the glue stored is unstable, thus Bubbles are randomly formed, which affects the accuracy of glue filling

Although the glue filling machine produced abroad has high precision, it has complex structure, high price and low work efficiency.
