Description

Technical Field

[0001] This application relates to the field of dispensing machine technology, and more particularly to a dispensing mechanism. Background Technology

[0002] In related technologies, dispensing machines use nozzles to spray adhesive to bond two components. However, the high pressure when the nozzle sprays adhesive can cause the adhesive to split and scatter. For example, when a dispensing machine is used for a camera module, the base of the camera module has a coated glass that is positioned opposite the lens. The edge of the coated glass has a screen-printed area to block stray light. To prevent dust from falling into the middle area of ​​the coated glass, dustproof adhesive is usually applied to the screen-printed area. However, the scattered adhesive can easily splash onto the surface of the coated glass to form dirt spots, which in turn affects the imaging performance of the camera module. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a dispensing mechanism that can block the branching and scattering of glue by means of an air wall when the glue is sprayed from the nozzle.

[0004] According to an embodiment of this application, a dispensing mechanism includes: a dispensing assembly having a nozzle for spraying adhesive; and a protective assembly mounted on the dispensing assembly and having an outlet for dispensing adhesive, the outlet for dispensing adhesive being in communication with the nozzle. The protective assembly further includes an airflow channel having an inlet and an outlet, the inlet being located on the side of the protective assembly away from the nozzle, and the outlet for dispensing adhesive being open in the same direction as the outlet for dispensing adhesive and surrounding the outlet for dispensing adhesive.

[0005] According to the dispensing mechanism of this application embodiment, by setting a protective component, and the air outlet of the airflow channel of the protective component is in the same opening direction as the dispensing port and is arranged around the dispensing port, the airflow can be discharged along the air outlet of the airflow channel to form an air wall around the dispensing port. In this way, when the nozzle sprays glue, the air wall can block the branching and scattering of the glue. Therefore, when applying dustproof glue to the screen printing area of ​​the coated glass of the camera module, the scattering of glue is not easy to splash onto the surface of the coated glass, thereby ensuring the imaging performance of the camera module.

[0006] According to some embodiments of the dispensing mechanism of this application, the air outlet is configured as an annular air outlet.

[0007] According to some embodiments of the dispensing mechanism of this application, the air outlet includes a plurality of sub-air outlets, which are spaced apart around the dispensing outlet.

[0008] According to some embodiments of the dispensing mechanism of this application, a plurality of air inlets are provided, and the plurality of air inlets are spaced apart around the dispensing outlet.

[0009] According to some embodiments of the present application, the dispensing mechanism includes a protective component comprising a base and a cover plate, the base being detachably connected to the dispensing component, the cover plate being connected to the base to define an airflow channel, the air inlet being disposed on the base, and the air outlet being disposed on the cover plate.

[0010] According to some embodiments of the dispensing mechanism of this application, the base and / or the cover plate are provided with an annular sealing portion, the annular sealing portion being located within the airflow channel and adapted to be fitted onto the nozzle.

[0011] According to some embodiments of the present application, the dispensing mechanism has an airflow channel arranged around the annular seal.

[0012] According to some embodiments of the dispensing mechanism of this application, the diameter of the dispensing orifice corresponds to and is the same size as the diameter of the nozzle.

[0013] According to some embodiments of the present application, the dispensing mechanism has a base with a first insertion slot, the dispensing assembly is inserted into the first insertion slot, the bottom wall of the first insertion slot has a second insertion slot, and the nozzle is inserted into the second insertion slot.

[0014] According to some embodiments of the present application, the dispensing mechanism includes a glue tank and a cylinder. The glue tank stores glue and is connected to the nozzle. The cylinder is used to drive the glue to be sprayed out of the nozzle. The cylinder is provided with an air outlet, which is connected to the air inlet.

[0015] According to the dispensing mechanism of this application embodiment, the dispensing assembly is provided with a nozzle for spraying glue, and the protective assembly is installed on the dispensing assembly and is provided with a glue outlet, which is connected to the nozzle; wherein, the protective assembly is also provided with an airflow channel, the airflow channel having an air inlet and an air outlet, the air inlet being located on the side of the protective assembly away from the nozzle, and the opening direction of the air outlet being the same as the opening direction of the glue outlet and arranged around the glue outlet, so that the airflow can be discharged along the air outlet of the airflow channel to form an air wall surrounding the glue outlet. Thus, when the nozzle sprays glue, the air wall can block the branching and scattering of the glue, so that when applying dustproof glue to the screen printing area of ​​the coated glass, the scattering of glue is not easily splashed onto the surface of the coated glass, thereby ensuring the imaging performance of the camera module.

[0036] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0038] The following is in conjunction with the appendix Figure 1-11 This application describes a dispensing mechanism 100 according to some embodiments.

[0039] like Figures 1-4 As shown, the dispensing mechanism 100 according to an embodiment of this application includes: a dispensing assembly 10 and a protective assembly 20.

[0040] like Figure 4 As shown, the dispensing assembly 10 is provided with a nozzle 11 for spraying adhesive. For example, the dispensing assembly 10 can be a mobile phone screen dispensing machine, a camera dispensing machine, etc.

[0041] Understandably, the dispensing assembly 10 can spray adhesive from the nozzle 11 to achieve the bonding effect of the structures that need to be bonded, such as dispensing and fixing the internal parts of the camera module, or dispensing the dispensing assembly 10 to apply dustproof adhesive to the screen-printed area of ​​the coated glass of the camera module.

[0042] Furthermore, the protective component 20 is mounted on the dispensing component 10, such as... Figure 5 As shown, the protective component 20 is provided with an adhesive outlet 21, and as... Figure 4 As shown, the glue outlet 21 is connected to the nozzle 11.

[0043] This ensures that after the protective component 20 is installed on the dispensing component 10, the adhesive sprayed from the nozzle 11 can be sprayed out from the dispensing port 21, thus ensuring the normal use of the dispensing component 10.

[0044] In some implementations, the diameter of the dispensing port 21 is the same as the diameter of the nozzle 11, and the center line of the dispensing port 21 is the same as the center line of the nozzle 11. This ensures that the setting of the protective component 20 will hardly affect the normal dispensing of the nozzle 11, so as to ensure the normal use of the dispensing component 10.

[0045] Among them, such as Figure 6 As shown, the protective component 20 is also provided with an airflow channel 22, which has an air inlet 221 and an air outlet 222. The air inlet 221 is located on the side of the protective component 20 away from the nozzle 11, and the opening direction of the air outlet 222 is the same as the opening direction of the glue outlet 21 and is arranged around the glue outlet 21.

[0046] Thus, after the protective component 20 is installed onto the dispensing component 10, air can be injected into the airflow channel 22 through the air inlet 221 so that airflow passes through the airflow channel 22 and is discharged along the air outlet 222. Since the air outlet 222 and the dispensing port 21 open in the same direction, and the glue sprayed from the nozzle 11 is finally sprayed out from the dispensing port 21, and the air outlet 222 is arranged around the dispensing port 21, the airflow discharged from the air outlet 222 will form an air wall on the circumferential outer side in the extending direction of the dispensing port 21. In this way, when the nozzle 11 sprays the glue, the air wall can block the glue from splitting and scattering. Thus, when applying the dustproof glue to the screen-printed area of ​​the coated glass of the camera module, the glue outlet 21 can correspond to the screen-printed area set on the edge of the coated glass. Then, when the glue is sprayed from the glue outlet 21, the glue scattering is blocked by the air wall and will also fall on the screen-printed area, thereby preventing the glue scattering from falling into the middle area of ​​the coated glass and forming dirt, thus ensuring the imaging performance of the camera module.

[0047] According to the dispensing mechanism 100 of this application embodiment, by providing a protective component 20, and the air outlet 222 of the airflow channel 22 of the protective component 20 is in the same opening direction as the dispensing port 21 and is arranged around the dispensing port 21, the airflow can be discharged along the air outlet 222 of the airflow channel 22 to form an air wall around the dispensing port 21. The diameter of the dispensing port 21 corresponds to and is the same size as the diameter of the nozzle 11. In this way, when the nozzle 11 sprays glue, the air wall can block the branching and scattering of the glue. Therefore, when applying dustproof glue to the screen printing area of ​​the coated glass of the camera module, the scattering of the glue is not easy to splash onto the surface of the coated glass, thereby ensuring the imaging performance of the camera module.

[0048] In some embodiments, such as Figure 7 As shown, the air outlet 222 is constructed as an annular air outlet 2221. This allows the airflow ejected from the air outlet 222 to form a circumferentially continuous air wall on the outer circumference of the glue outlet 21, thereby enhancing the blocking effect of the air wall on the branching and scattering of the glue.

[0049] In some embodiments, such as Figure 8 As shown, the air outlet 222 includes multiple annular air outlets 2222, which are spaced apart around the glue outlet 21. This allows the airflow ejected from the air outlet 222 to form a circumferentially continuous air wall on the outer circumference of the glue outlet 21, thereby enhancing the blocking effect of the air wall on the branching and scattering of the glue.

[0050] In some embodiments, such as Figure 5 As shown, multiple air inlets 221 are provided, and the multiple air inlets 221 are arranged at intervals around the glue outlet 21.

[0051] This ensures that the arrangement of multiple air inlets 221 does not interfere with the layout of the glue outlet 21, and the simultaneous intake of air through multiple air inlets 221 can improve airflow efficiency.

[0052] In some embodiments, such as Figure 6 and Figure 9 As shown, the protective assembly 20 includes a base 201 and a cover plate 202. The base 201 is detachably connected to the dispensing assembly 10, as shown below. Figure 6 As shown, the cover plate 202 is connected to the base 201 to define the airflow channel 22, the air inlet 221 is provided on the base 201, and the air outlet 222 is provided on the cover plate 202.

[0053] In this way, the airflow channel 22 can be defined by splicing the base 201 and the cover plate 202. This is simpler than setting the airflow channel 22 inside the protective component 20 of the overall structure, and it helps to reduce the difficulty of setting the airflow channel 22. In particular, it helps to reduce the difficulty of maintenance of the airflow channel 22 when it is blocked.

[0054] Meanwhile, the air inlet 221 is located on the base 201, and the air outlet 222 is located on the cover plate 202. For example, the base 201 can be located above the cover plate 202. This allows the air inlet 221 and the air outlet 222 to be located on different structural components, thereby creating a certain height difference between the air inlet 221 and the air outlet 222. This helps to increase the pressure at the air outlet 222, thereby improving the blocking effect of the air wall on the branching and scattering of the glue.

[0055] In some embodiments, the base 201 and / or cover plate 202 are provided with an annular sealing portion 203, which is located within the airflow channel 22 and is adapted to be fitted onto the nozzle 11.

[0056] For example, both the base 201 and the cover plate 202 are provided with an annular sealing part 203, or the annular sealing part 203 can be provided on the cover plate 202, or the annular sealing part 203 can be provided on the base 201, such as Figure 6 As shown, the annular sealing part 203 is located inside the airflow channel 22. In this way, the nozzle 11 can pass through the annular sealing part 203 to communicate with the dispensing port 21. The annular sealing part 203 can guide the assembly of the nozzle 11, thereby reducing the assembly difficulty of the nozzle 11 and the protective component 20. In addition, the annular sealing part 203 can limit the nozzle 11 to a certain extent, thereby enhancing the connection stability between the nozzle 11 and the protective component 20.

[0057] In particular, the annular sealing part 203 is located inside the airflow channel 22, so that the nozzle 11 also passes through the airflow channel 22, thereby utilizing the space inside the airflow channel 22 to assemble the nozzle 11, thereby improving space utilization and making the arrangement of the protective component 20 and the nozzle 11 more compact, which is conducive to realizing the miniaturization design of the dispensing mechanism 100.

[0058] Meanwhile, the annular sealing part 203 can seal the nozzle 11 and the airflow channel 22 on the circumferential outer side of the nozzle 11 to prevent airflow from entering the nozzle 11 or causing leakage at the nozzle 11, thereby improving the sealing performance of the airflow channel 22.

[0059] In some embodiments, such as Figure 10 As shown, the airflow channel 22 is arranged around the annular sealing portion 203. In this way, the space outside the annular sealing portion 203 can be fully utilized to form the airflow channel 22, thereby facilitating the increase of the volume of the airflow channel 22, and allowing the arrangement of the annular sealing portion 203 to utilize the space inside the airflow channel 22, thereby improving space utilization.

[0060] In some embodiments, the diameter of the dispensing orifice 21 corresponds to and is the same size as the diameter of the nozzle 11. This ensures that the protective component 20 has almost no impact on the normal dispensing of adhesive by the nozzle 11, thus guaranteeing the normal operation of the dispensing mechanism 100.

[0061] In some embodiments, such as Figure 11 As shown, the base 201 is provided with a first insertion slot 2011, and the dispensing assembly 10 is inserted into the first insertion slot 2011.

[0062] This allows the base 201 to be inserted into the dispensing assembly 10, thereby enhancing the connection stability between the base 201 and the dispensing assembly 10. Furthermore, by providing a first insertion slot 2011 on the base 201 for insertion into the dispensing assembly 10, the original size of the dispensing assembly 10 can be maintained, requiring only the base 201 to be modified. This reduces the difficulty and cost of installation and also helps to reduce the weight and volume of the base 201, thus facilitating the miniaturization of the protective assembly 20.

[0063] In some embodiments, such as Figure 11 As shown, the bottom wall of the first insertion groove 2011 is provided with a second insertion groove 2012, and the nozzle 11 is inserted into the second insertion groove 2012 to facilitate the positioning of the nozzle 11.

[0064] This allows the nozzle 11 to be inserted into the base 201, thereby enhancing the connection stability between the nozzle 11 and the base 201. Furthermore, the base 201 is provided with a second insertion slot 2012 for insertion into the nozzle 11, which allows the original size of the nozzle 11 to be changed, and only the base 201 needs to be modified. This reduces the difficulty and cost of installation, and also helps to reduce the weight and volume of the base 201, thus facilitating the miniaturization of the protective component 20.

[0065] In some embodiments, the annular sealing portion 203 forms a second insertion groove 2012, so that the annular sealing portion 203 has at least the function of sealing the nozzle 11 and realizing the insertion and engagement with the nozzle 11, thereby facilitating the functional integration design of the annular sealing portion 203.

[0066] In some embodiments, such as Figures 1-4 As shown, the dispensing assembly 10 includes a glue tank 101 and a cylinder 102. The glue tank 101 stores glue and is connected to the nozzle 11. The cylinder 102 is used to drive the glue to be sprayed out from the nozzle 11.

[0067] In this way, glue can be supplied to nozzle 11 by glue tank 101, and glue can be sprayed out by nozzle 11 by cylinder 102. Cylinder 102 is provided with air outlet 103, which is connected to air inlet 221.

[0068] The cylinder 102 is equipped with an air outlet 103, which is connected to the air inlet 221. This allows the existing air in the cylinder 102 to supply air to the airflow channel 22, enabling the protective component 20 to be designed in conjunction with the dispensing component 10. This eliminates the need for a separate air source for the airflow channel 22, thus reducing the difficulty of supplying air to the airflow channel 22.

[0069] Understandably, when cylinder 102 is working, the piston movement inside the cylinder drives the glue to be sprayed out of nozzle 11 by compressed air. At the same time, compressed air enters air inlet 221 through air outlet 103 and is sprayed out through air outlet 222, thus forming an air wall surrounding glue outlet 21.

[0070] Therefore, the dispensing mechanism 100 of this application, by setting a protective component 20, wherein the air outlet 222 of the airflow channel 22 of the protective component 20 is in the same opening direction as the dispensing port 21 and is arranged around the dispensing port 21, allows the airflow to be discharged along the air outlet 222 of the airflow channel 22 to form an air wall surrounding the dispensing port 21. The diameter of the dispensing port 21 corresponds to and is the same size as the diameter of the nozzle 11. In this way, when the nozzle 11 sprays glue, the air wall can block the branching and scattering of the glue. Thus, when applying dustproof glue to the screen printing area of ​​the coated glass of the camera module, the scattering of the glue is not easy to splash onto the surface of the coated glass, thereby ensuring the imaging performance of the camera module.
