Silicone filling head

Abstract

The invention relates to a glue dispensing machine, specifically a silicone grease filling head suitable for silicone grease and glue liquid with high viscosity and not easy to break, which is used to overcome the residue outside the hole when the existing silicone grease filling head is broken. Silicone grease caused problems with uncontrollable fill volumes. It consists of the filling needle and the master cylinder used to drive the filling needle into and out of the hole of the part being filled. The tail of the filling needle is hinged on the piston rod of the main cylinder. A filling needle swing mechanism is arranged beside the filling needle, which is used to drive the filling needle to swing around its hinge shaft. The head of the filling needle is provided with an inclined surface that can be attached to the inner wall of the hole of the part to be filled. In this silicone grease filling head, the setting of the filling needle swing mechanism and the filling needle with a sloped filling needle can make the glue breaking process complete on the inner wall of the hole of the part to be filled, ensuring that the set amount of silicone grease is completely It enters the hole of the part to be filled without remaining outside the hole, which ensures uniform and consistent filling, and then significantly improves the qualified rate and quality of the finished thermostat.

Description

technical field [0001] The invention relates to a glue dispensing machine, in particular to a silicone grease filling head suitable for silicone grease and glue liquid with high viscosity and difficult to break. Background technique [0002] Filling silicone grease is an important process in the production of thermostats. Each hose of the thermostat needs to be filled with 20-35 mg of silicone grease. If the filling amount of silicon grease is too small, the lubrication of the push rod will be insufficient, which will shorten the life of the thermostat; if the filling amount of silicon grease is too much, resulting in leakage of silicon grease, the lift will drop too much, cause the thermostat to fail. [0003] At present, most of the dispensing machines in the world and abroad adopt the glue-cutting method of vacuum back suction. This method is suitable for most viscosities of glue and grease, but it still cannot break the glue for silicone grease that cannot flow. An exi...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the amount of filling cannot be controlled due to the residual silicone grease outside the hole when the existing silicone grease filling head is broken, and to provide a silicone grease filling head with clean glue breaking and uniform filling volume.
