Description

Technical Field

[0001] This utility model relates to the field of grid dispensing technology, specifically a grid dispensing device for foldable screen mobile phones. Background Technology

[0002] Mesh dispensing equipment is a specialized automated device designed for precise dispensing in electronic manufacturing processes, particularly suitable for applications requiring high accuracy and repeatability. This equipment is commonly used in printed circuit board (PCB) assembly, semiconductor packaging, LED manufacturing, and other processes demanding extremely high dispensing precision. In the production of foldable screen phones, mesh dispensing technology can be used to ensure the screen's sealing and durability in the folding area.

[0003] The patent with publication number CN114749332A discloses an intelligent dispensing device for telephone core board production. It includes an operating table with a movable component mounted on top. A glue storage tube is mounted on top of the movable component, and a glue inlet tube is fixedly connected to the top of the glue storage tube. A transition glue box is located below the glue storage tube. A movable plate is slidably connected inside the transition glue box, dividing it into a left cavity and a right cavity. An air inlet one-way valve is installed on the side wall of the left cavity. A telescopic rod is fixedly connected between the movable plate and the transition glue box. Y-shaped connecting pipes are fixedly connected to both the upper and lower ends of the transition glue box, and these connecting pipes are connected to both the left and right cavities, with glue inlet one-way valves at each connection point. A nozzle is fixedly connected to the bottom of the connecting pipe. This device solves the problem that manual dispensing cannot meet industrial requirements, enabling intermittent and continuous glue dispensing, and is suitable for glue dotting, dripping, or line drawing operations.

[0004] However, the dispensing equipment in the aforementioned technology still has the following problems: when the dispensing head of the equipment drips adhesive onto the connection between the phone screen and the frame, the adhesive tends to form a hemispherical protrusion, making it difficult to fully penetrate the gap between the screen and the frame. After the adhesive cures, it may not be able to effectively ensure the connection strength between the gaps, resulting in an insufficiently firm connection between the screen and the frame, posing a risk of easy separation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grid dispensing device for foldable screen mobile phones, which improves the dispensing effect of the dispensing equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grid dispensing device for foldable screen mobile phones, including a dispensing machine installed on an operating table, a dispensing needle installed at the bottom of the dispensing machine, an air blowing component provided around the dispensing needle, an air guiding component connected to the side of the air blowing component near the dispensing machine, a filter component connected to the other end of the air guiding component, the filter component connected to the top of the dispensing machine, and a fan connected to the filter component.

[0007] Furthermore, the air blowing assembly includes a universal tube and a nozzle. One end of the universal tube is connected to the air guiding assembly, and the other end is fixedly connected to and connected to the nozzle.

[0008] Furthermore, the universal tubes and nozzles are provided in multiple sets, and all the universal tubes are connected to the air guiding assembly. Moreover, the multiple universal tubes are evenly and symmetrically distributed around the axis of the dispensing needle.

[0009] Furthermore, the air guiding assembly includes a dispersion ring and an air guiding tube. The dispersion ring is sleeved on the outside of the dispensing needle and fixedly connected to the bottom of the dispensing machine. The dispersion ring has a cavity inside. One end of the air guiding tube is fixedly connected to and communicates with the side wall of the dispersion ring, and the other end of the air guiding tube is connected to the filter assembly. The end of the universal tube away from the nozzle is fixedly connected to and communicates with the dispersion ring.

[0010] Furthermore, there are two air guide tubes, and the two air guide tubes are located on both sides of the dispensing machine.

[0011] Furthermore, the filter assembly includes a filter box, a door, and a framed filter screen. The filter box is fixedly connected to the top of the dispensing machine. The end of the air guide pipe away from the dispersion ring is fixedly connected to and communicates with the bottom side wall of the filter box.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5 A foldable screen mobile phone mesh dispensing device includes a dispensing machine 2 installed on an operating table 1. A dispensing needle 3 is installed at the bottom of the dispensing machine 2. An air blowing component 4 is provided around the dispensing needle 3. An air guiding component 5 is connected to the side of the air blowing component 4 near the dispensing machine 2. A filter component 6 is connected to the other end of the air guiding component 5. The filter component 6 is connected to the top of the dispensing machine 2. A fan 7 is connected to the filter component 6.

[0024] like Figures 1 to 5 As shown, the foldable screen mobile phone grid dispensing device of this utility model is structurally similar to existing grid dispensing devices, such as the intelligent dispensing device for telephone core board production disclosed in patent publication number CN114749332A. The main improvement of this utility model lies in improving the dispensing effect, such as... Figures 1 to 5As shown, in the foldable screen mobile phone mesh dispensing equipment of this utility model, when the dispensing machine 2 applies the adhesive to the gap between the mobile phone frame and the screen through the dispensing needle 3, the fan 7 is started, so that the external airflow enters the air guide component 5 through the filter component 6. The filter component 6 filters out impurities in the airflow, ensuring that the airflow entering the air guide component 5 is clean and free of impurities. Then, the airflow blows the adhesive applied to the gap between the mobile phone frame and the screen through the blowing component 4, using the airflow to accelerate the penetration of the adhesive into the gap at the dispensing position, preventing the adhesive from not being able to fully penetrate the gap between the screen and the frame due to too fast curing, thereby improving the dispensing effect. It should be noted that the power of the fan 7 can be changed and adjusted to a certain extent, so as to change the wind force according to the dispensing needs, further improving the blowing effect and avoiding blowing the adhesive away.

[0025] like Figures 2 to 5 As shown, the air blowing assembly 4 includes a universal tube 41 and a nozzle 42. One end of the universal tube 41 is connected to the air guiding assembly 5, and the other end is fixedly connected to and connected to the nozzle 42. The end of the nozzle 42 away from the universal tube 41 faces downwards from the dispensing end of the dispensing needle 3. The universal tube 41 allows the nozzle 42 to be oriented at any angle by bending, thus facilitating the adjustment of the air blowing direction and angle of the nozzle 42 according to the dispensing position, improving the applicability of the air blowing structure.

[0026] like Figures 2 to 5 As shown, multiple sets of universal tubes 41 and nozzles 42 are provided. All the universal tubes 41 are connected to the air guiding assembly 5, and the multiple universal tubes 41 are evenly and symmetrically distributed around the axis of the dispensing needle 3. Using multiple universal tubes 41 and nozzles 42 allows for more uniform and comprehensive airflow to the dispensing location, thereby increasing the penetration speed of the adhesive into the gaps and reducing the probability of the adhesive being blown away from the dispensing location, thus improving the stability of the dispensing operation.

[0027] like Figures 1 to 5 As shown, the air guiding assembly 5 includes a dispersing ring 51 and an air guiding tube 52. The dispersing ring 51 is sleeved on the outside of the dispensing needle 3 and fixedly connected to the bottom of the dispensing machine 2. The dispersing ring 51 has an internal cavity. One end of the air guiding tube 52 is fixedly connected to and communicates with the side wall of the dispersing ring 51, and the other end of the air guiding tube 52 is connected to the filter assembly 6. The end of the universal tube 41 away from the nozzle 42 is fixedly connected to and communicates with the dispersing ring 51. The clean airflow filtered by the filter assembly 6 enters the cavity inside the dispersing ring 51 through the air guiding tube 52, and flows evenly into the multiple universal tubes 41 through the cavity inside the dispersing ring 51, making the airflow speed in the multiple universal tubes 41 more uniform and improving the blowing effect.

[0028] like Figures 1 to 5As shown, there are two air guide pipes 52, and the two air guide pipes 52 are located on both sides of the dispensing machine 2. By setting two air guide pipes 52, air is simultaneously introduced from both ends of the cavity of the dispersion ring 51, making the air intake speed of the multiple universal tubes 41 more uniform, further improving the uniformity of the airflow blown onto the surface of the adhesive, and improving the blowing effect.

[0029] like Figures 1 to 5 As shown, the filter assembly 6 includes a filter box 61, a door 62, and a framed filter screen 63. The filter box 61 is fixedly connected to the top of the dispensing machine 2. The end of the air guide pipe 52 away from the dispersion ring 51 is fixedly connected to and communicates with the bottom side wall of the filter box 61. The door 62 is connected to the opening on one side of the filter box 61. The framed filter screen 63 is connected to the inner wall of the filter box 61 and is located above the air guide pipe 52. An air inlet 601 is provided through the top of the filter box 61. The fan 7 is fixedly connected to the top of the filter box 61 and covers the air inlet 601. The blower 7 blows air into the filter box 61 through the air inlet 601 at the top of the filter box 61. After the airflow passes through the frame filter screen 63, the clean and impurity-free airflow flows downward into the lower cavity of the filter box 61 and then enters the air guide pipe 52. This ensures that the airflow blown out from the nozzle 42 is free of impurities and dust, avoids contamination of the adhesive, and improves the stability and effect of the dispensing operation. When a lot of dust and impurities are retained on the frame filter screen 63 after long-term use, the box door 62 can be opened to replace and clean the frame filter screen 63, which affects the filtration effect of the adhesive blowing airflow.

[0030] like Figure 2 and Figure 3 As shown, the door 62 is fixedly connected to the filter box 61 by multiple bolts. A sealing gasket 64 is connected between the door 62 and the filter box 61, and the sealing gasket 64 abuts against the outer frame of the framed filter screen 63. The door 62 is fastened to the opening of the filter box 61 by multiple bolts, and the sealing gasket 64 is placed at the connection to prevent airflow inside the filter box 61 from leaking out from the door 62, while also preventing external dust and impurities from entering the interior through the connection between the door 62 and the filter box 61 and contaminating the blown adhesive airflow.

[0031] like Figures 1 to 5 As shown, mounting rails 65 are fixedly connected to the inner walls of both sides of the filter box 61. Several track grooves 602 are formed on the adjacent side of each mounting rail 65. The framed filter screen 63 is slidably connected to any symmetrically positioned track groove 602. When installing the framed filter screen 63, it is horizontally inserted into the track grooves 602 of the two mounting rails 65. Multiple framed filters 63 can also be installed in the corresponding track grooves 602 of the two mounting rails 65, thereby improving the filtration effect of the dispensing airflow.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
