[0033] Please refer to Figures 1-9 The illustration shows an air blowing device 1 for a dispensing machine provided in an embodiment of the present invention, comprising: an air guiding component 11, the air guiding component 11 having an air inlet 13, an air outlet 18 and an air guiding channel connecting the air inlet 13 and the air outlet 18, the air guiding component 11 also having a first channel 16 for the dispensing device 2 of the dispensing machine to pass through, the air outlet 18 being disposed close to the dispensing part 21 of the dispensing device 2, and the airflow being ejected sequentially through the air inlet 13, the air guiding channel and the air outlet 18 to form an air wall around the dispensing part 21.

[0034] The air outlet 18 is located at one end of the air guiding assembly 11 near the dispensing part 21 of the dispensing device 2. The air inlet 13 can be located at one end of the air guiding assembly 11 away from the dispensing part 21, or it can be located on the side of the air guiding assembly 11. The air inlet 13 can be located at other positions of the air guiding assembly 11 as needed, as long as it does not affect the connection between the air inlet 13 and the air outlet 18 of the air guiding channel. In this embodiment, the air inlet 13 is located at one end of the air guiding assembly 11 away from the dispensing part 21 for easy connection with the air source.

[0035] By setting an air inlet 13, an air outlet 18, and an air channel connecting the air inlet 13 and the air outlet 18 on the air guide assembly 11, the airflow forms an effective airflow wall around the dispensing part 21 of the dispensing device 2 after being sprayed out of the air outlet 18. The glue droplets generated during dispensing fall into the glue tank with the airflow, effectively preventing the glue droplets from falling onto the surface of the workpiece, solving the problem of poor workpiece appearance, and improving product quality and production efficiency.

[0036] In one embodiment, the air blowing device 1 further includes a plurality of air guides 14, which are disposed on the air guide assembly 11 and connected to the air outlet 18. The plurality of air guides 14 form a second channel 19 through which the dispensing part 21 passes. The airflow is ejected sequentially through the air outlet 18 and the air guides 14 to form an air wall around the dispensing part 21.

[0037] like Figures 1-7 As shown, multiple air guides 14 form a second channel 19 through which the dispensing part 21 passes. The multiple air guides 14 are arranged around the dispensing part 21 to facilitate the formation of a closed air wall by the airflow, effectively preventing the glue sprayed around the dispensing part 21 from falling onto the workpiece surface. The second channel 19 formed by multiple air guides 14 for the dispensing part 21 to pass can be polygonal. For example, three air guides 14 can form a second channel 19 with a triangular cross-section in the horizontal direction; four air guides 14 can form a second channel 19 with a quadrilateral cross-section in the horizontal direction; six air guides 14 can form a second channel 19 with a hexagonal cross-section in the horizontal direction, etc. The cross-section of the second channel 19 formed by multiple air guides 14 for the dispensing part 21 to pass can also be other shapes in the horizontal direction, as long as it is convenient for the dispensing part 21 to pass through, so that the airflow forms an air wall around the dispensing part 21. There are no restrictions here.

[0038] In one embodiment, the air guide 14 includes a first straight segment 141, an oblique segment 142, and a second straight segment 143. The first straight segment 141 is disposed on the air guide assembly 11 and connected to the air outlet 18. One end of the oblique segment 142 is connected to the first straight segment 141, and the other end of the oblique segment 142 is connected to the second straight segment 143. The second straight segment 143 is disposed perpendicular to the end face of the air guide assembly 11. The air guide 14 also includes an air guide hole 144, which passes through the first straight segment 141, the oblique segment 142, and the second straight segment 143 and is connected to the air outlet 18.

[0039] like Figure 2 , Figure 4 and Figure 6As shown, the oblique line segment 142 gathers the second straight line segment 143 around the dispensing part 21, making it easier for the airflow ejected from the air guide hole 144 to surround the dispensing part 21 and form an air wall. At the same time, it can also enhance the guiding force of the airflow, so that more glue droplets fall into the glue tank under the guidance of the airflow, further reducing the glue droplets falling on the surface of the workpiece and improving the appearance and quality of the workpiece. In addition, the second straight line segment 143 is set perpendicular to the end face of the air guide component 11, so that the second straight line segment 143 is set parallel around the dispensing part 21. The airflow surrounds the dispensing part 21 to form a parallel airflow wall. Under the guidance of the airflow wall, the glue droplets can only follow the airflow into the glue tank, improving the guiding efficiency of the airflow wall and improving the appearance defects of the workpiece.

[0040] In one embodiment, there are at least three air guides 14, and the second straight segments 143 on the plurality of air guides 14 form a second channel 19 through which the dispensing part 21 passes. The airflow is ejected sequentially through the air outlet 18 and the air guide hole 144 to form an airflow wall around the dispensing part 21.

[0041] In one embodiment, there are three air guides 14. The second straight segment 143 on the three air guides 14 forms a second channel 19 through which the dispensing part 21 passes. The cross-section of the second channel 19 in the horizontal direction is triangular, so that after the airflow is ejected from the air outlet 18 and the air guide hole 144, it surrounds the dispensing part 21 to form a sealed airflow wall, thereby enhancing the guiding force of the airflow wall.

[0042] In one embodiment, there are four air guides 14. The second straight segment 143 on the four air guides 14 forms a second channel 19 through which the dispensing part 21 passes. The cross-section of the second channel 19 in the horizontal direction is quadrilateral, so that after the airflow is ejected from the air outlet 18 and the air guide hole 144, it surrounds the dispensing part 21 to form an air wall with a better sealing effect, further enhancing the guiding force of the airflow wall.

[0043] like Figures 3-5 As shown, in this embodiment, there are six air guides 14. The second straight segment 143 on the six air guides 14 forms a second channel 19 through which the dispensing part 21 passes. The cross-section of the second channel 19 in the horizontal direction is hexagonal, so that after the airflow is ejected from the air outlet 18 and the air guide hole 144, it surrounds the dispensing part 21 to form an air wall with a better sealing effect, further enhancing the guiding force of the airflow wall.

[0044] In one embodiment, multiple air inlets 13 and multiple air outlets 18 are provided, and multiple air guiding channels are provided. Each air guiding channel includes a first air guiding channel 131 and a second air guiding channel 181. The first air guiding channel 131 is connected to the air inlet 13 in a one-to-one correspondence, and the second air guiding channel 181 is connected to the air outlet 18 in a one-to-one correspondence. At least one first air guiding channel 131 is connected to at least one second air guiding channel 181.

[0045] The number of air inlets 13, air outlets 18, and air guide channels can be set according to the ease of processing and the airflow connectivity. For example, one first air guide channel 131 can be connected to one second air guide channel 181, so that one air inlet 13 corresponds to one air outlet 18; or one first air guide channel 131 can be connected to at least two second air guide channels 181, so that one air inlet 13 corresponds to at least two air outlets 18; or at least two first air guide channels 131 can be connected to one second air guide channel 181, so that at least two air inlets 13 correspond to one air outlet 18; or at least two first air guide channels 131 can be connected to at least two second air guide channels 181, so that multiple air inlets 13 correspond to multiple air outlets 18.

[0046] In one embodiment, the air guiding assembly 11 has at least one third air guiding channel 17 inside, which is connected to at least one first air guiding channel 131 and at least one second air guiding channel 181.

[0047] like Figures 5-7 As shown, by setting the third air guide channel 17, it is convenient to connect the first air guide channel 131 and the second air guide channel 181.

[0048] In one embodiment, there are at least two third air channels 17, and the third air channels 17 are arc-shaped, with all the third air channels 17 located on the same circumference.

[0049] like Figures 5-7 As shown, by providing multiple third air guide channels 17 inside the air guide assembly 11, it is convenient to connect multiple first air guide channels 131 and multiple second air guide channels 181. This is beneficial to the convenience and stability of airflow connection, and also to the convenience of processing.

[0050] In one embodiment, each third air passage 17 is connected to at least two second air passages 181.

[0051] like Figures 5-7 As shown, a third air guide channel 17 enables a first air guide channel 131 to be connected to multiple second air guide channels 181, and enables an air inlet 13 to be connected to multiple air outlets 18, thereby enhancing the utilization efficiency of airflow.

[0052] In one embodiment, the air blowing device 1 further includes a connecting bushing 12, which is detachably connected to the air guiding assembly 11 and fitted inside the first channel 16.

[0053] like Figures 1-3 , Figures 6-7 as well as Figure 9As shown, on the one hand, the connecting bushing 12 makes it easier to connect to the dispensing device 2, and on the other hand, it improves the processing convenience of the air blowing device 1.

[0054] In one embodiment, the air blowing device 1 further includes positioning holes 15 that pass through the air guiding assembly 11 and the connecting bushing 12 in sequence and are symmetrically arranged, for use in conjunction with the fixing member to fix the air blowing device 1 and the dispensing device 2.

[0055] like Figure 1 As shown, the positioning hole 15 makes it easier to fix the air blowing device 1 and the glue dispensing device 2 together with the fixing component.

[0056] Another embodiment of this application also provides a dispensing machine, including a dispensing device 2, an air source, and an air blowing device 1 provided in the foregoing embodiments. The air blowing device 1 is sleeved on the dispensing device 2 and is connected to the air source.

[0057] The dispensing device 2 is the dispensing valve of the dispensing machine. The dispensing valve can be a dispensing spray valve, a pneumatic valve, a screw valve, a metering valve, a dispensing needle valve, etc., and is not limited here. In this embodiment, the dispensing device 2 is a dispensing spray valve.

[0058] The dispensing section 21 is the dispensing part of the dispensing device 2. The dispensing section 21 can be a needle, nozzle, or spray nozzle used for dispensing adhesive from the dispensing device 2, and there is no limitation on it. In this embodiment, the dispensing section 21 is the nozzle of the dispensing spray valve.

[0059] like Figures 8-9 As shown, the air blowing device 1 is mounted on the glue dispensing device 2. When the lens assembly 4 and the motor 5 are assembled, the glue dispensing part 21 of the glue dispensing device 2 sprays glue to fix the lens assembly 4 and the motor 5. A glue groove is provided at the connection between the lens assembly 4 and the motor 5. An air source (not shown in the figure) sprays air into the air blowing device 1 and then sprays it out from the air blowing device 1, forming a strong airflow wall around the glue dispensing part 21. The glue droplets sprayed by the glue dispensing part 21 of the glue dispensing device 2 fall into the glue groove under the guidance of the airflow, preventing the glue droplets from falling on the surface of the motor 5 and causing appearance defects. This protects the motor and improves the glue dispensing quality and production efficiency.

[0060] In one embodiment, the dispensing machine further includes a fixing member, and the air blowing device 1 is provided with a positioning hole 15. The fixing member fixes the air blowing device 1 and the dispensing device 2 through the positioning hole 15.

[0061] The air blowing device 1 and the glue dispensing device 2 are fixed by fasteners (not shown in the figure) and positioning holes 15, ensuring the stability of the connection.

[0062] In one embodiment, the dispensing machine further includes a connector 3 and a connecting pipe. One end of the connector 3 is connected to the air inlet 13, and the other end of the connector 3 is connected to one end of the connecting pipe. The other end of the connecting pipe is connected to an air source.

[0063] like Figures 8-9 As shown, the air inlet 13 is connected to the air source through the connector 3 and the connecting pipe (not shown in the figure), which facilitates the formation of the airflow wall.

[0064] In this embodiment, the dispensing machine is equipped with an air blowing device 1 on the dispensing device 2. The airflow from the air source is sprayed out through the air blowing device 1 to form an airflow wall around the dispensing part 21. The airflow wall guides the glue droplets sprayed from the dispensing part 21 into the glue tank, effectively preventing the glue droplets from falling onto the surface of the workpiece. This solves the problem of poor product appearance and greatly improves product quality and production efficiency.

[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
