Common types include instant adhesives, epoxy resin adhesives, anaerobic adhesives, UV adhesives, hot melt adhesives, pressure-sensitive adhesives, and latex adhesives. Existing adhesives are typically stored in plastic bottles, and users dispense the adhesive by squeezing the bottle, controlling the amount dispensed by adjusting the squeezing pressure. However, this method of dispensing is inaccurate. Therefore, a fully automated, precise adhesive application device is proposed. Utility Model Content

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a fully automatic precision glue application device, including a cylinder 1. Inside the cylinder 1, from top to bottom, there are a storage chamber 4, a counterweight chamber 5, and a discharge chamber 10. The storage chamber 4 and the counterweight chamber 5, as well as the counterweight chamber 5 and the discharge chamber 10, are all connected by pipes 8. Each pipe 8 is equipped with a valve body 12. The counterweight chamber 5 has a double-layer structure, and the inner layer of the counterweight chamber 5 is an elastic diaphragm. A first airbag 2 is provided inside the jacket of the counterweight chamber 5. A ventilation mechanism is provided outside the cylinder 1, which can deliver gas into the first airbag 2.

[0018] In this embodiment, the storage cavity 4 is used to store glue. When applying glue, the user can use the ventilation mechanism to deliver gas into the first airbag 2 to adjust the space inside the elastic diaphragm, thereby controlling the storage space of glue inside the elastic diaphragm and achieving the purpose of controlling the amount of glue applied.

[0019] Furthermore, the ventilation mechanism includes a second airbag 6 sleeved on the outer surface of the cylinder 1. The second airbag 6 is connected to the first airbag 2 via a connecting pipe 3. A first electric push rod 7 is fixedly installed inside the cylinder 1. The telescopic end of the first electric push rod 7 can compress the first airbag 2.

[0020] Furthermore, a piston plate 9 is provided inside the storage cavity 4, and a second electric push rod 13 is fixedly connected to the surface of the piston plate 9. The fixed end of the second electric push rod 13 is fixedly connected to the upper end of the cylinder 1, and the upper end of the cylinder 1 is hollow.

[0021] Furthermore, a sealing ring is fitted on the outer surface of the piston plate 9, and the sealing ring slides and seals with the inner wall of the storage cavity 4.

[0022] Furthermore, the bottom surface of the discharge chamber 10 is provided with uniformly distributed through holes 11.

[0023] In this embodiment, the first electric push rod 7 is extended, and the telescopic end of the first electric push rod 7 can squeeze the second airbag 6. The gas inside the second airbag 6 is delivered to the first airbag 2. The first airbag 2 expands and pushes the elastic diaphragm, thereby adjusting the storage space of the glue inside the elastic diaphragm. After adjustment, the valve body 12 inside the pipe 8 between the storage chamber 4 and the counterweight chamber 5 is opened, and the second electric push rod 13 is extended, driving the piston plate 9 to move. The piston plate 9 squeezes the glue inside the storage chamber 4 into the elastic diaphragm. After delivery, the valve body 12 is closed, and the other valve body 12 is opened. The first electric push rod 7 is then extended to continue supplying air to the first airbag 2. The first airbag 2 expands and squeezes the elastic diaphragm. The glue inside the elastic diaphragm enters the discharge chamber 10 through the pipe 8 and is evenly discharged through the through hole 11.
