Adjustable glue pouring control mechanism

Abstract

Disclosed is an adjustable glue pouring control mechanism. Pump heads include a first pump head unit and a second pump head unit, and the first pump head unit and the second pump head unit are installed at the front end of a pump body in a left-and-right abreast mode. A first glue control mechanism and a second glue control mechanism are arranged in the pump body in the mode of corresponding to the first pump head unit and the second pump head unit. Each pump head unit comprises a front pump head and a rear pump head. A pump head core in the middle, an upper valve base and a lower valve base are arranged in each front pump head. A solution storage cavity is formed in each pump head core. Feeding inlets and discharging outlets of the upper valve bases and the lower valve bases are communicated with the solution storage cavities through check valves. A plunger which conducts backward return through a compression spring is arranged in each rear pump head. A piston rod at the front end of each plunger is arranged in the corresponding front pump head through a piston cavity, wherein each piston cavity is communicated between the corresponding front pump head and the corresponding rear pump head. The solution storage cavities are communicated with the piston cavities in the front pump heads, and the solution storage cavities located between the left pump head cores and the right pump head cores are communicated. The first glue control mechanism comprises a first cam and a second cam. The second glue control mechanism comprises a first cam and a second cam. The first cams and the second cams control the first glue control mechanism and the second glue control mechanism to conduct continuous glue absorption and discharge. By the adoption of the adjustable glue pouring control mechanism, the glue pouring flow is continuous and controllable, and the glue pouring speed is adjustable according to the different glue solution viscosity.

Description

technical field [0001] The invention relates to parts of a glue filling machine, in particular to an adjustable glue filling control mechanism. Background technique [0002] The glue pouring machine is also called a glue spreader, or a glue dispenser, or a glue machine, or a glue dispensing machine, etc. It is specially used to control the flow or volume of the quantitatively coated liquid glue, and apply the liquid glue to the product drop by drop or quantitatively. The automatic machine on the surface or inside the product can realize the automatic operation of multi-path glue filling and dispensing. It is widely used in internal glue filling and external packaging and fixed installation of electronic products, especially for internal glue filling or dispensing of electronic components such as electromechanical control components. Due to the small size of electronic components such as electromechanical control components, it is difficult to There are precise requirements ...

AI Technical Summary

Problems solved by technology

[0005] The existing glue filling control mechanism has problems such as poor glue filling control accuracy, unadjustable glue filling speed, and the inability to realize the miniaturization of the glue filling control mechanism.
