Description

Rubber tube heating sleeve Technical Field The utility model relates to the technical field of dispensing equipment, in particular to a rubber tube heating sleeve. Background In a plurality of fields such as electronic packaging, precise assembly, industrial automation and the like, glue sizing is used as a key connecting, sealing and bonding process, and is widely applied to industrial production processes such as circuit board packaging, LED dispensing, hardware assembly, automobile part sealing and the like. Along with the expansion of application fields and the improvement of performance requirements, the requirements of a sizing system on the fluidity, sizing precision and sizing stability of glue are also higher and higher. In current glue applying equipment, especially in adopting the rubber tube to carry glue to the structure of glueing syringe needle from glue storage device, because the viscosity of glue in the transportation is higher, especially under low temperature environment, glue can become more thick, leads to out the glue unsmoothly, glueing inhomogeneous, glue volume unstable scheduling problem. This phenomenon is particularly evident in winter environments or in workshops with strict requirements for constant temperature. In order to improve the glue-out performance, the prior art has mainly focused on the following ways: 1. The needle head local heating structure is that the existing sizing equipment generally adopts a mode of heating a needle head or a nozzle, and heating is carried out around the sizing needle head by arranging elements such as an electric heating wire, a ceramic heater and the like. Although the fluidity of the glue at the needle head can be improved to a certain extent by the mode, the heating area is extremely small, and the glue in the rubber tube can not be conveyed for a long distance to play a role in adjusting the temperature, so that the problem of unsmooth glue outlet caused by sticky glue in the rubber tube still exists. 2. The glue preheating storage tank structure is that part of equipment adopts a glue storage tank with a heating function, and the whole heating treatment is attempted to be carried out on the glue before the glue is sent out. However, as the glue storage tank and the glue outlet are still connected through the glue pipe, the heating is limited to the glue storage stage, and the glue pipe part is still in an exposed environment and is obviously influenced by the environmental temperature. The temperature of the glue is reduced in the conveying process, the glue still can be thickened again or even be partially coagulated, and the glue outlet performance is still not ideal. 3. And in the application of partial high-end sizing, the whole sizing area or the sizing device is covered by the whole heating box, so that the sizing environment temperature is increased. However, the mode has high cost, high energy consumption and complex structure, is not suitable for dispensing equipment with small volume and compact structure, and is also unfavorable for later maintenance and local structure replacement. In summary, the heating means of the existing sizing equipment are mainly concentrated at the needle end or the glue storage end, and no structural solution for effectively heating the glue in the hose has been formed. In practice, most of the flowing paths of the glue in the gluing process are in the rubber tube, and especially under the working conditions of flexible silicone tubes, long-path conveying, intermittent gluing and the like, the glue in the rubber tube is extremely easily affected by the ambient temperature and has severe temperature fluctuation, so that the glue is unstable and even blocked. In addition, because the heating area and the rubber tube are in a non-integral structure in the existing equipment, the maintenance process is complicated, and when the glue or the rubber tube is replaced, the heating device is often required to be removed, the heating position is repositioned, and the needle head is calibrated, so that the glue application production efficiency and the operation convenience are seriously affected. Therefore, the market is urgent to need a heating structure capable of directly heating glue in a rubber tube, and meanwhile, the heating structure has the characteristics of compact structure, firm connection, convenience in installation and strong detachability, so that stable and reliable glue outlet control, simple and convenient daily maintenance and wide industrial adaptability are realized. Disclosure of utility model The utility model relates to a rubber tube heating sleeve, and aims to provide a device which is simple in structure, convenient to operate and capable of effectively improving glue fluidity and glue application stability. Specifically, the utility model solves the problems of poor fluidity and unstable sizing caused by higher viscosity of glue or lower environmental temperature in the existing
