Technical Field
[0001] This application relates to the field of automatic AB glue mixing machine technology, and in particular to an automatic mixing and dispensing machine with excellent mixing performance. Background Technology
[0002] The AB glue automatic mixing and dispensing machine is an automated device specifically designed for the precise mixing, metering, and dispensing of two-component adhesives. The existing automatic AB glue mixing and dispensing machine consists of a material tank, a conveying system, a mixing system, and a dispensing control system. The mixing system is responsible for the thorough and uniform mixing of the two components. The degree of mixing directly determines the quality of the subsequent dosing products. The mixing process is generally carried out by a servo motor driving the stirring shaft to rotate and stir. After mixing, the glue is extruded from the dispensing nozzle for use. The mixing time is relatively short, and occasionally the AB glue is uneven, resulting in dosing and glue detachment, which leads to product quality problems. Summary of the Invention
[0003] The purpose of this invention is to provide an automatic AB glue mixing and dispensing machine, which differs from the traditional rotary stirring method. It is the first to use a voice coil motor, which uses the ultra-high frequency vibration of the voice coil motor mover to achieve rapid mixing of the liquid. Since there is no direct connection between the voice coil motor mover and the voice coil motor stator, the voice coil motor mover can be directly and sealed inside the mixing chamber, avoiding the overflow of the mixed glue. Compared with the traditional rotary stirring method, the structure is simpler.
[0004] To address the technical problem of low mixing efficiency in existing AB glue automatic mixing and dispensing machines, this invention provides an AB glue automatic mixing and dispensing machine, comprising a valve block, a mixing chamber within the valve block, a dispensing port at the bottom of the mixing chamber, an A glue inlet pipe and a B glue inlet pipe on opposite sides of the mixing chamber, a barrel at the top of the mixing chamber, the bottom of the barrel extending into the mixing chamber, the edge of the barrel opening sealingly connected to the inner wall of the mixing chamber, the barrel opening communicating with the outside of the valve block, a voice coil motor stator embedded within the barrel, and a voice coil motor mover surrounding the barrel, the voice coil motor mover being disposed within the mixing chamber.
[0005] Furthermore, the present invention provides an automatic AB glue mixing and dispensing machine, wherein the valve block includes a valve cover and a valve seat, the inner wall of the valve cover is engraved with an upper valve cavity, the inner wall of the valve seat is engraved with a lower valve cavity, the valve cover is fitted onto the valve seat, the upper valve cavity and the lower valve cavity are combined to form the glue mixing chamber, the A glue inlet pipe and the B glue inlet pipe are both opened on the valve seat, the outer end of the A glue inlet pipe is connected to the A glue injection pump and the inner end is connected to the glue mixing chamber, the outer end of the B glue inlet pipe is connected to the B glue injection pump and the inner end is connected to the glue mixing chamber.
[0006] Furthermore, the present invention provides an automatic AB glue mixing and dispensing machine, wherein the valve block is made of POM material.
[0007] Furthermore, the present invention provides an automatic AB glue mixing and dispensing machine, wherein a servo motor is installed on the outside of the barrel opening, the output shaft of the servo motor is connected to a stirring shaft through a coupling, the stirring shaft sequentially passes through the voice coil motor stator and the bottom of the barrel and extends into the mixing chamber, and a stirring impeller is installed at the inner end of the stirring shaft.
[0008] Furthermore, the present invention provides an automatic AB glue mixing and dispensing machine, wherein the stirring impeller includes a disc and a plurality of stirring blades evenly distributed along the circumference of the disc, the plurality of stirring blades surrounding the outer periphery of the voice coil motor actuator, and the inner end of the stirring shaft is connected to the disc.
[0009] Furthermore, the present invention provides an automatic AB glue mixing and dispensing machine, wherein a linear slide rail is provided on the outer wall of the barrel, and a slot is provided on the inner wall of the voice coil motor mover, the slot being adapted to the linear slide rail.
[0010] The automatic AB glue mixing and dispensing machine provided in this application has the following advantages compared with the prior art: On the one hand, unlike traditional rotary stirring methods, this application is the first to use a voice coil motor. The ultra-high frequency vibration of the voice coil motor mover achieves rapid mixing of the mixture, and the high-frequency vibration mixing effect is superior to that of rotary stirring. On the other hand, there is no direct connection between the voice coil motor mover and the voice coil motor stator. The voice coil motor mover can be directly and sealed inside the mixing chamber, avoiding the overflow of the mixed glue. The structure is simpler than that of traditional rotary stirring methods.

[0016] like Figures 1-4As shown, this embodiment provides an automatic AB glue mixing and dispensing machine, which includes a valve block made of POM material. A mixing chamber is provided inside the valve block, and a dispensing port 2 is provided at the bottom of the mixing chamber. An A glue inlet pipe 3 and a B glue inlet pipe 4 are respectively provided on both sides of the mixing chamber. The valve block includes a valve cover 5 and a valve seat 6. An upper valve cavity 7 is engraved on the inner wall of the valve cover 5, and a lower valve cavity 1 is engraved on the inner wall of the valve seat 6. The valve cover 5 covers the valve seat 6. The upper valve cavity 7 and the lower valve cavity 1 combine to form the mixing chamber. Both the A glue inlet pipe 3 and the B glue inlet pipe 4 are located on the valve seat 6. The outer end of the A glue inlet pipe 3 is connected to an A glue injection pump, and the inner end is connected to the mixing chamber. The outer end of the B glue inlet pipe 4 is connected to an A glue injection pump. The end is connected to the B-type glue injection pump, and the inner end is connected to the mixing chamber. A barrel 8 is provided at the top of the mixing chamber. The barrel 8 and the valve seat 6 are integrally formed. The bottom of the barrel 8 extends into the mixing chamber. The edge of the barrel opening of the barrel 8 is sealed to the inner wall of the mixing chamber. The barrel opening is connected to the outside of the valve body. The stator 9 of the voice coil motor is embedded in the barrel 8. The mover 10 of the voice coil motor is installed outside the barrel 8. The mover 10 of the voice coil motor is located in the mixing chamber. In order to ensure that the mover 10 of the voice coil motor performs a linear reciprocating vibration along the outer wall of the barrel 8, a linear slide rail 11 is provided on the outer wall of the barrel 8. A slot 12 is provided on the inner wall of the mover 10 of the voice coil motor. The slot 12 is adapted to the linear slide rail 11. As a preferred embodiment, this application further adds a rotary stirring method. A servo motor 13 is installed on the outside of the barrel opening. The output shaft of the servo motor 13 is connected to a stirring shaft 15 via a coupling 14. The stirring shaft 15 sequentially passes through the voice coil motor stator 9 and the bottom of the barrel body 8, extending into the mixing chamber. A stirring blade 17 is installed at the inner end of the stirring shaft 15. The stirring blade 17 includes a wheel 16 and a plurality of stirring blades 17 evenly distributed around the circumference of the wheel 16. The plurality of stirring blades 17 surround the outer periphery of the voice coil motor mover 10. The inner end of the stirring shaft 15 is connected to the wheel 16. The AB glue is efficiently mixed through two dimensions: high-frequency vibration from above and below and rotary stirring.
[0017] The usage process and principle of an automatic AB glue mixing and dispensing machine in this embodiment are as follows: Glue A injection pump adds glue A into the mixing chamber through glue A inlet pipe 3, while glue B injection pump adds glue B into the mixing chamber through glue B inlet pipe 4. The voice coil motor stator 9 is energized, and the voice coil motor mover 10 moves under the force of the magnetic field. When the current direction of the voice coil motor stator 9 is changed, the voice coil motor mover 10 moves in the opposite direction. Based on this principle, the voice coil motor mover 10 can reciprocate within the mixing chamber. Because the groove 12 on the inner wall of the voice coil motor mover 10 engages with the linear slide rail 11 on the outer wall of the barrel 8, the voice coil motor mover 10 is forced to vibrate up and down at high frequency along the linear slide rail 11. This is different from traditional rotary stirring. The methods are completely different. High-frequency vibration can drive the AB glue in the mixing chamber to form a violent turbulence, resulting in excellent mixing effect. In addition, in order to further improve the mixing effect, this embodiment also designed a rotary stirring scheme. A servo motor 13 is installed above the barrel 8. After the servo motor 13 is powered on, the stirring shaft 15 drives the stirring blade 17 to rotate and stir. The combined action of high-frequency vibration and rotary stirring can ensure that the two glues are fully mixed. When cleaning is required, the screws are unscrewed and the valve cover 5 is removed to take out the voice coil motor mover 10 and the stirring blade 17 for cleaning. At the same time, the mixing chamber, the A glue inlet pipe 3 and the B glue inlet pipe 4 are also cleaned.

Therefore, any technical solutions that can be obtained by those skilled in the art based on the concept of this application through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
