Description

Technical Field

[0001] This utility model relates to the field of dispensing device technology, and more specifically, to an AB glue plunger-type dispensing mechanism. Background Technology

[0002] In modern industrial production, dispensing processes are widely used in the assembly and sealing of components in fields such as electronics, automobiles, and aerospace. Especially for applications requiring high-precision, high-reliability connections, AB glue (two-component adhesive) is the preferred material due to its excellent bond strength, weather resistance, and chemical stability. However, the use of AB glue involves the precise mixing and immediate application of two or more components, which places high demands on the design of the dispensing equipment.

[0003] Common dispensing machines for AB glue often experience issues such as inaccurate ratios of the two types of glue, inaccurate dispensing amounts during production, and jamming of the reversing mechanism when the dispensing valve is filling the glue. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by proposing an AB glue plunger-type dispensing mechanism, aiming to solve at least one of the problems mentioned in the background art.

[0005] This utility model provides an AB glue plunger-type dispensing mechanism, comprising: a mounting back plate with a protective shell on its top; a first servo motor housed inside the protective shell; a sliding seat fixedly connected to the sliding end of the first servo motor; two sealing shafts on one end of the sliding seat; and a sliding sealing connection between the ends of the sealing shafts away from the sliding seat and a cavity. Two second servo motors are also mounted on the top of the mounting back plate. The output ends of the two second servo motors are respectively connected to the input ends of two right-angle reducers, and the output ends of the two right-angle reducers are respectively fixedly connected to a single-row connector. The shaft has two induction plates fixedly connected to the side walls of the two inline couplings. A sensor is provided on the inner wall of the protective shell corresponding to the induction plates. A ceramic core is fixedly connected to the top of the two inline couplings. A tungsten steel sleeve is rotatably and sealingly connected to the outer side walls of the two ceramic cores. The two tungsten steel sleeves are located inside the rotating seat, and the side walls of the two tungsten steel sleeves are fixedly and sealingly connected to the inner wall of the rotating seat. A first through hole and a reflux groove are provided on the ceramic core. A second through hole and a liquid inlet hole are provided on the tungsten steel sleeve. The cavity communicates with the first through hole and the second through hole.

[0006] A liquid inlet assembly is disposed on the top of the protective shell, and the output end of the liquid inlet assembly is connected to the cavity through the liquid inlet hole, the reflux groove and the first through hole;

[0007] A liquid dispensing assembly is disposed on the side of the rotating seat away from the cavity, and the liquid dispensing assembly communicates with the first through hole and the second through hole.

[0008] In some embodiments, the second servo motor and the two cavities are all disposed inside the protective shell. A support plate is disposed inside the protective shell. The support plate is arranged horizontally, and the side wall of the support plate is fixedly connected to the inner wall of the protective shell. The mounting ends at the bottom of the two cavities are fixedly connected to the top of the support plate.

[0009] In some embodiments, a first sealing port is provided on the side of the cavity near the sealing shaft, the sealing shaft extends into the interior of the cavity through the first sealing port, the side wall of the sealing shaft is slidably sealed to the inner wall of the first sealing port, and a first connection port is provided on the side of the cavity away from the sealing shaft.

[0010] In some embodiments, the bottom of the first servo motor is fixedly connected to the top of the mounting backplate via a pad.

[0011] In some embodiments, the rotating seat is provided with two second connection ports corresponding to the two first connection ports. The first connection ports and the second connection ports are provided in correspondence. The second through hole communicates with the interior of the cavity through the second connection ports and the first connection ports.

[0012] In some embodiments, the first through hole penetrates the ceramic core, and the second through hole penetrates the tungsten steel sleeve.

[0013] In some embodiments, the liquid inlet assembly includes:

[0014] A cylinder bracket, the bottom of which is fixedly connected to the mounting back plate, and two cylinders are fixedly connected to the top of the cylinder bracket, with a rubber piston fixedly connected to the telescopic end of each of the two cylinders.

[0015] A glue bucket bracket is provided on the top of the protective shell. Two glue buckets can be fixed on the glue bucket bracket, and the glue bucket bracket is correspondingly arranged with the two glue bucket pistons.

[0016] A glue bucket inlet seat is fixedly connected to the rotating seat. The glue bucket inlet seat has two connecting pipes inside.

[0021] In some embodiments, pressure sensors are provided on both the rotating base and the connecting base.

[0022] Compared with existing technologies, the advantages of this invention are as follows: Two second servo motors control the rotation of the ceramic cores of adhesives A and B, enabling independent supply and flow regulation of the two adhesives, ensuring precise and controllable mixing ratios (e.g., 1:1 or customized ratios), and avoiding errors from manual mixing. Before formal dispensing, the cavity can be pre-filled with adhesive, reducing fluctuations in dispensing volume due to unstable supply and improving consistency. The rotation of the ceramic core switches the connection between the return groove and the through hole, allowing adhesives A and B to be fully mixed within the cavity before being discharged through the outlet channel, ensuring uniform mixing and preventing adhesive sedimentation or stratification. The first servo motor drives the sealing shaft to compress the cavity, providing stable pressure output and ensuring accurate adhesive quantity and a continuous and smooth dispensing process. The combination of the tungsten carbide sleeve and the ceramic core (high hardness of tungsten carbide and low friction of ceramic) significantly improves the wear resistance of key components, extends equipment life, and reduces maintenance frequency. Pressure sensors built into the rotating seat and connecting seat provide real-time feedback on adhesive pressure, enabling closed-loop control and timely warnings of blockages or abnormal adhesive supply.
