Description

Technical Field

[0001] This utility model relates to the field of adhesive dispensing equipment technology, and in particular to an automatic adhesive dispensing machine. Background Technology

[0002] Currently, the preparation of adhesives for film coating is usually done manually. First, a certain amount of the main agent is weighed according to the ratio and put into the mixing tank. Then, a certain amount of the solvent is weighed according to the ratio and put into the mixing tank. Next, an air pump is used to stir for several minutes. After stirring, a fixed amount of curing agent is weighed according to the ratio and put into the mixing tank, and then stirred for several minutes.

[0003] Existing adhesive mixing equipment uses a pneumatic diaphragm pump to extract the main component. Once the set amount is reached, a four-way valve is opened to clean the pipeline. After cleaning, the four-way valve is closed, and then the solvent is extracted. After extraction, the first stirring is performed. After the first stirring, the set amount of curing agent is extracted. Once the set amount is reached, the four-way valve is opened, the pipeline is cleaned, and a second stirring is performed. After stirring, the mixture is pumped into a container and transported to the site for use. However, this type of adhesive mixing equipment has low weighing accuracy during the extraction of the main component, solvent, and curing agent, making it unsuitable for actual production. Furthermore, due to the complex pipeline, the adhesive frequently solidifies, causing blockages.

[0004] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0067] The glue dispensing process of this automatic glue dispensing machine is as follows:

[0068] 1. Enter commonly used glue formulas in advance via the touch screen, and set the required mixing time, settling time, and weighing compensation on the touch screen;

[0069] 2. Place the glue bucket 600 on the weighing module 500. The pushing mechanism 400 pushes the glue bucket 600 into the cabinet 100. Press the tare button on the weighing display to remove the extra weight.

[0070] 3. Press the reset button on the touchscreen to clear the previous glue mixing data. Select the desired formula on the formula interface and set the amount of glue to mix for one bucket;

[0071] 4. Press the start button, and the lifting mechanism 300 will drive the lifting base plate 200 to rise automatically, lifting the glue bucket 600 to the top position. After it is in position, the glue bucket 600 will rest against the upper cabinet plate 120 of the cabinet 100 to prevent glue from splashing out during glue dispensing.

[0072] 5. Once in place, the main agent dispensing mechanism 800a begins to extract the main agent and inject it into the glue bucket 600. The weight of the main agent can be seen in real time on the touch screen, and the percentage of main agent extracted can also be seen on the touch screen. The process of extracting the main agent is recorded in real time.

[0073] 6. Once the main agent extraction is complete (reaching 100%), allow 20 seconds of settling time to prevent water ripples from disturbing the weighing. After the settling time, the solvent dispensing mechanism 800b begins to extract solvent and inject it into the glue tank 600, just like when extracting the main agent. After this process, allow the solvent to stand again to prevent water ripples from disturbing the weighing.

[0074] 7. After the main agent and solvent are extracted, the stirring mechanism 700 will stir once. After stirring, let it stand to prevent water ripples.

[0075] 8. After mixing, the curing agent dispensing mechanism 800c starts to draw the curing agent and inject it into the glue bucket 600. After that, let it stand. After standing, the mixing mechanism 700 starts to mix again.

[0076] 9. Once mixing is complete, the entire adhesive preparation process is finished. All of the above steps are automated.

[0077] 10. The staff member presses the descent button on the touch screen again, and the glue bucket 600 descends. After it descends to the bottom, the pushing mechanism 400 pushes the glue bucket 600 out, and the staff member moves the glue bucket.
