Description

Double-component glue metering device

Technical Field

The utility model relates to a rubber coating equipment technical field, concretely relates to bi-component glue metering device.

Background

In order to meet the requirements of sealing, shock resistance, noise reduction, corrosion resistance, comfort and the like of the automobile, relevant parts of the automobile body need to be coated with glue. The gluing is one of indispensable links of processes such as welding, coating, power assembly, battery and the like in automobile production. According to the composition of the adhesive, the automobile gluing mainly comprises two processes of single-component gluing and double-component gluing (the double-component gluing is also called double-component gluing in the industry). Because the main agent (generally called A glue) and the curing agent (catalyst, also called B glue) of the double-component glue are separately packaged, before mixing, a single component can not react with air to be cured, so that the double-component glue is more stable during storage, has longer effective period and is widely applied. The bi-component glue metering device is a key device for gluing, and for bi-component gluing, the proportioning precision is a key process parameter for ensuring the strength or other important properties (such as the heat-conducting property of the heat-conducting glue) of the adhesive.

In the prior art, for a metering device of two-component glue, there is a two-component servo metering cylinder with chinese patent publication No. CN113019833B, which discloses a glue feeding mechanism a and a glue feeding mechanism B, where the glue feeding mechanism a and the glue feeding mechanism B have the same structure, and according to the structure of the glue feeding mechanism described in the patent (including servo motor, cylinder body, electric cylinder screw, plunger rod, etc.), the skilled in the art knows that the two-component servo metering cylinder is a common double-servo piston type quantitative cylinder in the art, and each glue feeding mechanism includes a piston type quantitative cylinder, and the structure can realize the alternate circulation of filling and discharging of glue in the up-and-down movement of the piston rod, and the structure can have very high precision for two-component glue with small component ratio difference.

However, when the structure is used for processing two-component glue with a large proportion, the glue discharging speed of one quantitative cylinder needs to be adjusted very fast, the glue discharging speed of the other quantitative cylinder needs to be controlled very slowly, and for the quantitative cylinder with a fast glue discharging speed, the integral filling time of the cylinder body is long, so that the glue supply is discontinuous, the glue supply is inaccurate, and the glue supply precision is poor; if the time of filling is to be compensated, the size of one of the quantitative cylinders needs to be designed to be very large, but in such a case, many parts related to the quantitative cylinder need to be simultaneously made to be large, which not only increases the weight and volume of the equipment, but also increases the cost of the equipment.
