Glue dispending machine

Abstract

The invention discloses a glue dispensing machine. The glue dispensing machine comprises a working platform, a positioning base, a mounting vertical column, a glue dispensing mounting sliding seat, a glue dispensing servo motor, liquid moving devices, a glue absorbing air cylinder, a glue discharging air cylinder and a PLC, wherein the positioning base is arranged on a working platform; the mounting vertical column is vertically arranged on the working platform and positioned on one side of the positioning base; the glue dispensing mounting sliding seat is installed on a sliding rail of the vertical column in a sliding configuration mode and positioned above the positioning base; the glue dispensing servo motor is mounted on a mounting vertical column and is connected with the glue dispensing mounting sliding seat trough a transmission mechanism; the liquid moving devices are horizontally mounted on the glue dispensing mounting sliding seat at intervals; the glue absorbing air cylinder is installed in the glue dispensing mounting sliding seat; the glue discharging air cylinder is installed in the glue dispensing mounting sliding seat; and the PLC is connected with the glue dispensing servo motor, the glue absorbing air cylinder and the glue discharging air cylinder. According to the glue dispensing machine, the liquid moving devices are adopted for glue dispensing, glue bonding phenomenon is not easy to occur in the liquid moving devices, just a glue dispensing needle is replaced if bonding is appeared in the glue dispensing needle, operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of glue dispensing machines, in particular to a glue dispensing machine for riveting joints between automobile micro-motor casings and reduction box bodies. Background technique [0002] see figure 1 , shown in the figure is a schematic diagram of the assembly of the automobile micro-motor casing and the aluminum alloy reduction box body. The automobile micro-motor casing 10 and the aluminum alloy reduction box body 20 are connected by riveting. There are two riveting points 31 and 32 at the junction of the aluminum alloy reduction box body 20. However, due to the dimensional tolerances of the parts, there is a certain looseness after the automotive micro-motor casing 10 and the aluminum alloy reduction box body 20 are riveted. 502 glue fills the loose gap between the automobile micro-motor casing 10 and the aluminum alloy reduction box 20 to ensure the strength and stability of riveting.

Problems solved by technology

However, the work efficiency of this method is low, and the dispensing effect is not ideal, and the labor cost is high

There are also dispensing machines used to realize dispensing at the two riveting points 31 and 32 at the junction of the automotive micro-motor casing 10 and the aluminum alloy reduction box body 20, but the dispensing machines currently on the market basically use the peristaltic method. And XYZ mobile platform dispensing, the hose is often sticky, glue cannot be released, and it is not easy to detect whether the glue is released
