[0002] In various industries, dispensing has become an indispensable key technology in the production process. Through the dispensing nozzle 99 shown in Figures 1 and 2, glue / adhesive is precisely applied to specific locations for bonding, sealing, protecting, filling, or assembling different components. However, the glue / adhesive, along with dust in the environment, can cause the dispensing nozzle 99 to become clogged. Therefore, it is necessary to regularly check the cleanliness of the dispensing nozzle 99 and promptly clean any clogged nozzles. Summary of the Invention

[0007] Figure 1 shows the structural appearance of the dispensing needle tip. Figure 2 is a cross-sectional view of the dispensing needle. Figure 3 is a structural appearance diagram of the present invention. Figure 4 is a partial enlarged view of the structure of the present invention. Figure 5 is a schematic diagram of the structural block of the present invention. Implementation
[0008] First, please refer to Figures 3 to 5. The present invention includes: A frame 10 is divided into a spray chamber 11, which is connected to an exhaust pipe 12; A spray washing station 20 is installed on the frame 10. The spray washing station 20 is provided with a tray positioning groove 21 and at least one spray washing liquid outlet 22. A dispensing nozzle carrier 30 can be positioned in the carrier positioning groove 21, and the dispensing nozzle carrier 30 can accommodate at least one dispensing nozzle 99 for placement and positioning. A cleaning solution supply unit 40 is provided on the frame 10, including a cleaning solution tank 41, a pump 42, a filter element 431, and a cleaning solution supply pipe 43. The cleaning solution tank 41 is located below the cleaning table 20 to receive the cleaning solution discharged from the cleaning solution outlet 22. The head end of the cleaning solution supply pipe 43 is connected to the cleaning solution tank 41. The pump 42 and the filter element 431 are connected in series to the cleaning solution supply pipe 43. A gas-liquid mixer 50 is mounted on the frame 10. The gas-liquid mixer 50 has a positive pressure gas supply port 51, a spray liquid supply port 52, and a two-fluid output port 53. The tail end of the spray liquid supply pipe 43 is connected to the spray liquid supply port 52. A positive pressure gas source 60 is connected to the head end of a pressure supply pipe 61, the tail end of which is connected to the positive pressure gas supply interface 51; and A two-fluid spray washer 70 has a two-fluid inlet 71 and at least one two-fluid nozzle 72. The two-fluid spray washer 70 is mounted on a transverse device 80, which is mounted on the frame 10. The two-fluid inlet 71 and the two-fluid outlet 53 are connected via a two-fluid delivery pipe 73. A controller 90 is electrically connected to the transverse device 80 and the pump 42.
[0009] Furthermore, when the cleaning solution loses its cleaning ability after repeated cleaning processes, it must be replaced. Therefore, the system also includes a waste liquid exchange pipe 44 and a waste liquid exchange pump 45. The first end of the waste liquid exchange pipe 44 is connected to the cleaning solution tank 41, and the second end is connected to a waste liquid tank 46. The waste liquid exchange pump 45 draws the waste cleaning solution from the cleaning solution tank 41 into the waste liquid tank 46 through the waste liquid exchange pipe 44. Additionally, the system also includes a new solution exchange pipe 47 and a new... A liquid exchange pump 48 is used. The tail end of the new liquid exchange pipe 47 is connected to the spray cleaning liquid tank 41, and the head end of the new liquid exchange pipe 47 is connected to a new liquid tank 49. The new liquid exchange pump 48 draws new spray cleaning liquid from the new liquid tank 49 into the spray cleaning liquid tank 41 through the new liquid exchange pipe 47. In addition, the spray cleaning platform 20, the two-fluid spray cleaner 70 and the transverse movement device 80 are arranged inside the spray cleaning chamber 11 to prevent the escape of uncomfortable gas generated during the spray cleaning process, and the gas can be discharged through the exhaust pipe 12.
[0010] Based on this configuration, the dispensing needles 99 to be cleaned can be placed into the dispensing needle carrier tray 30 (as shown in Figure 4, 3 rows * 6 columns of dispensing needles 99 can be placed). The dispensing needle carrier tray 30 is then positioned in the carrier positioning groove 21. The controlled transverse movement device 80 drives the two-fluid spray cleaner 70 to reciprocate transversely, so that the three two-fluid nozzles 72 spray cleaning liquid towards the dispensing needle carrier tray 30, thereby cleaning the plurality of dispensing needles 99. Thus, the present invention has the function of cleaning a plurality of dispensing needles simultaneously.
[0011] However, the cleaning fluid sprayed by the two-fluid nozzle 72 is supplied to the gas-liquid mixer 50 by the cleaning fluid supply unit 40, and the gas flow is continuously supplied to the gas-liquid mixer 50 by the positive pressure gas source 60. The gas-liquid mixer 50 mixes the cleaning fluid and the gas flow to form a micro-atomized two-fluid cleaning fluid. By using two-fluid technology to make the cleaning fluid particles more micro-atomized, the cleaning cleanliness of the dispensing needle nozzle can be greatly improved. Therefore, the present invention has the effect of greatly improving the cleaning cleanliness of the dispensing needle nozzle by using a micro-atomized two-fluid cleaning fluid. Furthermore, after the dispensing needle nozzle is cleaned, the cleaning fluid supply unit 40 can be controlled to stop supplying the cleaning fluid, and the two-fluid nozzle 72 only sprays gas to dry the cleaned dispensing needle nozzle.
[0012] In conclusion, the technical means disclosed in this invention do indeed possess the requirements for invention patents, namely "novelty," "progressiveness," and "industrial applicability." I humbly request that Your Excellency grant me a patent to encourage invention. I am deeply grateful for your kindness.
[0013] However, the above-disclosed drawings and descriptions are merely preferred embodiments of the present invention. Modifications or equivalent changes made by those skilled in the art within the spirit and scope of this application should still be included within the scope of the patent application.
