Description

Technical Field

[0001] This invention relates to the field of glue gun technology, and more specifically to a radial glue dispensing auxiliary device. Background Technology

[0002] Glue guns have been widely used in industries such as construction, electrical and electronic products, and furniture. By applying glue, they can achieve excellent waterproofing, sealing, and beautification effects.

[0003] However, with the continuous improvement of equipment precision and complexity, traditional caulking guns can no longer meet the needs. For example, some parts have annular grooves on the walls of their holes. When applying caulking guns into these grooves, the caulking must be done radially from the groove to complete the application. Although traditional caulking guns can apply caulking to the annular grooves radially from the hole by adding an extension tube or a specially shaped curved nozzle, the constant rotation and adjustment while applying caulking makes it difficult to ensure even application. Furthermore, a trimmer is required after application, which is not only difficult to operate but also time-consuming and labor-intensive. Summary of the Invention

[0004] In view of this, the present invention provides a radial glue application auxiliary device, which aims to make radial glue application simpler and more uniform.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A radial glue dispensing auxiliary device, characterized in that: it includes a connector body, the connector body is provided with a connecting structure, and an assembly chamber is provided inside. The connecting structure is used to connect with the dispensing nozzle of a glue bottle. The top of the assembly chamber is provided with an axial channel extending upward through the upper end of the connector body. The circumferential sidewall of the assembly chamber is distributed with first radial channels. A rotating plug is rotatably disposed in the assembly chamber. The rotating plug has an annular inner cavity inside. The upper end of the annular inner cavity has an opening communicating with the axial channel. The annular inner cavity is arranged in a circular array with blades. Each blade divides the annular inner cavity into multiple second radial channels. The inner end of each second radial channel communicates with the opening. The outer end of each second radial channel penetrates the circumferential sidewall of the rotating plug.

[0007] With the above structure, by rotating the rotating plug and the circumferentially evenly distributed blades, when the glue enters the interior of the connector body, it can enter the annular inner cavity through the openings, and then flow evenly in the circumferential direction through the second radial channel between the blades, thereby achieving radial glue application to the annular groove. When radial glue application to the annular groove is required, the connector body only needs to be placed in the center of the annular groove, making the operation very convenient.

[0008] Preferably, the bottom of the annular inner cavity is provided with a tapered portion facing the opening, and the axis of the tapered portion is collinear with the axis of the glue bottle's dispensing nozzle. This structure facilitates the uniform transformation of the glue from an axial position to circumferential dispersion.

[0009] Preferably, the blades are arranged in a spiral array around the circumference of the conical portion. This structure facilitates the adhesive in driving the rotating plug to rotate.

[0010] Preferably, a first bearing is provided between the side of the connector body away from the glue bottle nozzle and the rotating plug, and a second bearing is provided between the side of the connector body near the glue bottle nozzle and the rotating plug. With this structure, the first and second bearings assist the rotating plug in rotation, thereby making radial glue application more uniform.

[0011] Preferably, the first bearing is a thrust ball bearing, and the second bearing is a thrust self-aligning roller bearing. With this structure, the first and second bearings can redirect the axial pressure of the adhesive on the rotating plug to all directions.

[0012] Preferably, the connector body is provided with a limiting part in the circumference, which can support the connector body on the surface of the part to be glued. This structure serves to limit movement and ensures that the auxiliary device will not vibrate or shift during use.

[0013] Preferably, the connector body has an inwardly contracting annular groove at the lower edge of the outer end corresponding to the first radial channel. With this structure, when the part to be glued is filled with glue and then the connector body is removed, the sidewall of the connector body can act as a scraper, and excess glue in the annular groove can be used to fill the unfilled portions of the part's hole wall, eliminating the need for subsequent secondary finishing.

[0014] Preferably, the lower end of the assembly chamber is provided with an installation opening, the diameter of which is greater than or equal to the outer diameter of the rotating plug. A pressure plate is threaded onto the installation opening, and the thrust ball bearing abuts against the pressure plate and the rotating plug. This structure facilitates the installation and disassembly of the various components of the auxiliary device.

[0015] Preferably, the connection structure is a threaded mounting head. This structure ensures a secure connection between the glue bottle nozzle and the auxiliary device.

[0016] Preferably, the rotating plug has an opening facing the glue bottle nozzle on its side near the nozzle, and the connector body has a connecting ring facing the opening inside, with the opening looped around the outside of the connecting ring. This structure ensures the assembly accuracy between the rotating plug and the connector body, and also ensures that the glue enters the rotating plug directly from the axial channel, preventing it from entering the location of the second bearing through other gaps and affecting its service life.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The radial glue application auxiliary device provided by this invention converts the axial flow of glue into the rotation of the blade by rotating the rotating plug, thereby achieving the purpose of radially and uniformly applying glue to the annular groove on the hole wall of the part. In actual use, it is only necessary to place the connector body in the hole of the part, which is very convenient to operate.

[0019] 2. When the adhesive fills the radial hole wall, the annular groove circumferentially set in the connector body is also filled with adhesive. At this time, the connector body is pulled away from the hole wall of the part. The side wall of the connector body can act as a scraper, and the adhesive in the annular groove can effectively fill the gaps that still exist on the radial hole wall, saving the need for subsequent secondary repairs.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] This embodiment uses the application of a caulking gun to the annular groove 7a on the bottom plate of a new energy vehicle battery box as an example for illustration. Please refer to... Figure 3 The battery box base plate 7 is provided with a mounting hole 7b, and the wall of the mounting hole 7b has an annular groove 7a. Since the gap involved in the annular groove 7a in the manufacturing process of the battery box base plate 7 is a weld, applying glue can not only fill the groove, but also play a role in corrosion prevention and shock absorption.

[0031] like Figures 1 to 7 As shown, a radial glue dispensing auxiliary device includes a connector body 1, a connecting structure 11 at the upper end of the connector body 1, and an assembly chamber 1a formed inside the connector body 1. The connecting structure 11 is used to connect to the dispensing nozzle of a glue bottle 6. First radial channels 1c are distributed on the circumferential sidewall of the assembly chamber 1a. A rotating plug 2 is rotatably installed inside the assembly chamber 1a. An annular inner cavity 2a is formed inside the rotating plug 2. The upper end of the annular inner cavity 2a has an opening 2b communicating with an axial channel 1b. Blades 21 are also arranged in a circular array inside the annular inner cavity 2a. Each blade 21 divides the annular inner cavity 2a into multiple second radial channels 2c. The inner end of each second radial channel 2c communicates with the opening 2b, and the outer end of each second radial channel 2c penetrates the circumferential sidewall of the rotating plug 2.

[0032] With this design, when the glue comes out of the nozzle of the glue bottle 6, it can enter the annular inner cavity 2a inside the rotating plug 2 through the axial channel 1b and the opening 2b, then enter the first radial channel 1c through the second radial channel 2c, and finally enter the annular groove 7a. The arrayed blades 21 allow the glue to flow evenly in the circumferential direction into the annular groove 7a, thereby achieving the purpose of uniformly applying glue to the annular groove 7a.

[0033] like Figures 4 to 6 As shown, a tapered portion 22 is formed at the bottom of the annular inner cavity 2a, facing the opening 2b. The axis of the tapered portion 22 is collinear with the axis of the dispensing nozzle of the glue bottle 6. This design helps the glue entering the annular inner cavity 2a axially to flow evenly in all directions along the outer surface of the tapered portion 22.

[0034] In this embodiment, the blade 21 is spiral-shaped, as detailed in the following example. Figure 5 Since the rotating plug 2 is installed inside the connector body 1, the blades 21 of the spiral structure allow the glue to spiral into the annular groove 7a, which helps to push the rotating plug 2 to rotate, thereby ensuring that the glue is applied more evenly inside the annular groove 7a.

[0035] In order to facilitate the fixed installation of the connector body 1 and the dispensing nozzle of the glue bottle 6, in this embodiment, the connector body 1 and the dispensing nozzle of the glue bottle 6 are installed by thread, the connecting structure 11 is a threaded mounting head, and the connecting structure 11 is formed on the upper end of the connector body 1.

[0036] In this embodiment, a limiting part 12 is formed circumferentially on the connector body 1. When the connector body 1 is placed at the hanging hole 7b of the battery box bottom plate 7, the limiting part 12 can support the outer surface of the hanging hole 7b, playing a supporting and limiting role, ensuring that the connector body 1 will not shake when the glue gun 8 is applying glue.

[0037] like Figure 8 As shown, a first bearing 3 is installed between the bottom of the rotating plug 2 and the connector body 1, and a second bearing 4 is installed between the top of the rotating plug 2 and the connector body 1. The first bearing 3 and the second bearing 4 cooperate to assist the rotating plug 2 in rotating, making the rotating plug 2 rotate more smoothly and the glue application more even. In this embodiment, the first bearing 3 is preferably a thrust ball bearing, and the second bearing 4 is preferably a thrust self-aligning roller bearing. With this design, the first bearing 3 and the second bearing 4 can assist the rotating plug 2 in rotating while also diverting the axial pressure of the glue on the rotating plug 2 to all directions.

[0038] Furthermore, an opening 23 is formed on the top of the rotating plug 2, and a vertically downward connecting ring 14 is formed inside the connector body 1. The opening 23 is fitted onto the outer ring of the connecting ring 14. This design ensures the assembly accuracy between the rotating plug 2 and the connector body 1, and ensures that the adhesive enters directly from the axial channel 1b into the opening 2b, and then diffuses circumferentially along the second radial channel 2c. This effectively prevents the adhesive from entering the second bearing 4 through the gap between the connector body 1 and the rotating plug 2, thereby ensuring the service life of the second bearing 4.

[0039] like Figure 7 and Figure 9 As shown, an inwardly contracting annular groove 13 is provided at the lower edge of the outer end of the first radial channel 1c corresponding to the connector body 1. When both the annular groove 7a and the annular groove 13 are filled with glue, the connector body 1 is pulled out from the hook hole 7b. The side wall of the connector body 1 acts as a scraper, and the glue in the annular groove 13 can be used to fill any air bubbles that may exist in the circumference of the annular groove 7a, eliminating the need for secondary trimming with a scraper later.

[0040] To facilitate the installation of various components of the auxiliary device, in this embodiment, the lower end of the assembly chamber 1a is provided with an installation opening, and the diameter of the installation opening is greater than or equal to the outer diameter of the rotating plug 2. A pressure plate 5 is threaded onto the installation opening, and the thrust ball bearing abuts between the pressure plate 5 and the rotating plug 2. Based on this, the rotating plug 2, the first bearing 3, and the second bearing 4 can be installed and removed from the bottom of the connector body 1.

[0041] Based on the above structure, combined with Figure 2 and Figure 9 The steps and principles of this invention in actual use are as follows: First, select a connector body 1 with a size suitable for the mounting hole 7b on the bottom plate 7 of the battery box. Screw the connector body 1 onto the dispensing nozzle of the glue bottle 6. Place the connector body 1 into the mounting hole 7b. At this time, the limiting part 12 abuts against the outer surface of the bottom plate 7 of the battery box. Press the glue gun 8 so that the glue enters the axial channel 1b from the dispensing nozzle of the glue bottle 6 and flows directly to the top of the conical part 22 along the axial channel 1b. Then, the glue spreads circumferentially along the outer surface of the conical part 22 and finally spirals evenly into the annular groove 7a along the forming direction of each blade 21. At this time, the first bearing 3 and the second bearing 4 convert the axial pressure applied by the glue to the rotating disk 2 into circumferential dispersion and assist the rotating disk 2 in rotating. Once the annular groove 7a is filled with glue, the connector body 1 is pulled out of the mounting hole 7b. At this point, the side wall of the connector body 1 acts as a scraper, making the circumferential wall of the annular groove 7a smoother. Excess glue in the annular groove 13 can be used to fill any air bubbles that may exist in the circumferential wall of the annular groove 7a. This design not only makes radial glue application to the mounting hole 7b more convenient but also ensures more even glue application. The fit between the annular groove 13 and the side wall of the connector body 1 eliminates the need for subsequent scraping repair steps.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention. Those skilled in the art, under the guidance of the present invention, can make various similar representations without departing from the spirit and claims of the present invention, and such modifications all fall within the protection scope of the present invention.
