Gluing equipment for muffler shell

Abstract

The utility model discloses a glue coating device for a muffler shell, comprising: a working platform, a glue dispensing mechanism that injects glue in a liquid storage tube to the surface of a workpiece through a glue dropper nozzle by means of a pressure pump. Before dispensing glue, the air pump pipe is connected to the pneumatic joint 1 and the pneumatic joint 2, and then the workpiece is placed on the adsorption block, and the air pump is started. Since the air pump draws out the air in the adsorption block, the workpiece is adsorbed on the adsorption head, and then the pressure pump is started. The compressed air in the pressure pump is injected into the liquid storage tube through the connecting pipe and the connecting head, and the colloid in the liquid storage tube is dispensed to the surface of the workpiece through the glue dropper nozzle. In this process, since the high-speed gas blown out from the pneumatic joint 1 continuously blows the blades of the rotating wheel to make the rotating wheel rotate, the connecting shaft fixedly connected to one side of the rotating wheel drives the stirring ball to stir the colloid at the lower end of the liquid storage tube to prevent the colloid from precipitating and affecting the overall dispensing process.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the gluing device for the muffler shell:

[0019] 1. The glue dispensing mechanism facilitates the smooth flow of glue in the liquid storage tube. Before glue dispensing, connect the air pump pipe to pneumatic connector 1 and pneumatic connector 2, and then place the workpiece on the adsorption block. The colloid in the liquid storage tube is dispensed to the surface of the workpiece through the glue dispensing needle nozzle. In this process, the high-speed gas blown out from pneumatic connector 1 continuously blows the blades of the rotating wheel to make the rotating wheel rotate. The connecting shaft fixedly connected on one side of the rotating wheel drives the stirring ball to stir the colloid at the lower end of the liquid storage tube to prevent the precipitation of the colloid from affecting the overall glue dispensing process. In addition, the air flow is increased during the blowing process, which accelerates the cooling and molding of the colloid on the workpiece surface.

[0020] 2. The adsorption mechanism solves the problem of workpiece displacement caused by the movement of mobile platform 2 during the three-axis dispensing process. During the three-axis dispensing process, since the moving speed of mobile platform 2 is relatively high, if the workpiece placed on the upper end of mobile platform 2 has a large inertia, the workpiece is very likely to be displaced during the movement of mobile platform 2. This mechanism uses an adsorption block and an adsorption head to quickly position the workpiece, thereby preventing the occurrence of displacement. Compared with the use of a fixture for fixing, this mechanism is more convenient and will not damage the surface of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
