Description

Technical Field

[0001] This application relates to the field of adhesive application equipment technology, and more particularly to a glue gun assembly. Background Technology

[0002] To prevent rainwater from seeping into the vehicle's interior, drainage channels are typically installed to allow rainwater to drain smoothly and prevent damage. To enhance the vehicle's aesthetics, the joints between the metal panels that make up the vehicle's exterior are usually located within these drainage channels and then connected using welding or other methods. To improve the sealing performance of the drainage channels, adhesive is applied to the joints between the metal panels within the channels.

[0003] In existing technologies, glue is usually applied manually using a glue gun in a water tank. This makes it impossible to control the movement of the nozzle during the glue application process, which can lead to uneven glue application. Insufficient glue application can easily cause problems such as water leakage, while excessive glue application can easily interfere with the installation of subsequent components. Utility Model Content

[0004] The purpose of this application is to provide a glue gun assembly that aims to solve the problem of how to improve the uniformity of glue application in vehicle water tank glue application operations.

[0005] This application provides a glue gun assembly for applying glue to a vehicle's drainage channel. The glue gun assembly includes a glue gun body and a magnetic component. The glue gun body includes a fixing structure and a nozzle connected to the fixing structure. The fixing structure is used to fix a glue bottle, and the nozzle is used to allow the glue in the bottle to flow out into the drainage channel. The magnetic component is connected to the glue gun body and is used to magnetize the nozzle so that the nozzle can adhere to the inner wall surface of the drainage channel.

[0006] In the above solution, the glue gun body is connected to a magnetic component, which magnetizes the nozzle, making the nozzle magnetic. During the glue application process on the water tank, the nozzle magnetically adheres to the inner wall of the water tank. Due to the magnetic attraction between the nozzle and the inner wall of the water tank, the glue gun remains in close contact with the inner wall during application. This ensures that the movement trajectory of the glue gun aligns with the direction of the joints between the metal plates within the water tank, improving the uniformity of the glue application. This prevents insufficient glue from affecting the sealing performance and avoids excessive glue from interfering with the installation of subsequent components.

[0012] Optionally, the wear-resistant component is a metal gasket.

[0013] Optionally, the surface where the nozzle outlet is located is a first surface, and the connection between the first surface and the surface where the anti-wear component is located is a contact portion. The contact portion is used to contact the bottom wall surface of the water tank, and at least a portion of the anti-wear component covers the contact portion.

[0027] To facilitate understanding of the technical solutions provided in the embodiments of this application, the application scenarios of the glue gun assembly provided in the embodiments of this application are described below:

[0028] To improve a vehicle's drainage performance and prevent rainwater and snowmelt from seeping into the vehicle and damaging internal components, drainage channels need to be installed in different parts of the vehicle. For example, drainage channels can be installed on the roof to drain water from areas such as the sunroof; drainage channels can be installed in the trunk to drain water from the rear cargo area.

[0029] To enhance the vehicle's aesthetics, the joints of the metal sheets that make up the vehicle's exterior are typically located within the drainage channel, and these sheets are then joined using methods such as welding. This results in seams between the metal sheets and weld points within the drainage channel. To ensure the drainage channel's sealing performance, an adhesive is applied inside. This adhesive fills and covers the gaps between the metal sheets and the weld points, improving the seal at the joints and preventing rainwater corrosion of the weld points.

[0030] In existing technology, a 1.5mm nozzle 2 is typically used to apply adhesive to the joints of metal sheets within a flow channel. Because the movement trajectory of the nozzle 2 during the adhesive application process is uncontrollable, and its trajectory is inconsistent with the extension direction of the joint, uneven adhesive application occurs along this direction. For example, with a constant dispensing speed, if the nozzle 2's movement trajectory aligns with the joint's extension direction, the adhesive application at each joint will be consistent. However, with a constant dispensing speed, if the nozzle 2's movement trajectory deviates from the joint's extension direction in a certain segment, exhibiting an S-shape or zigzag pattern, the adhesive application at that location will be greater than at other locations, resulting in uneven application. Due to this uneven application, a brush is needed after application to smooth the adhesive and fill the joint.

[0031] The glue gun assembly provided in this application is mainly used when the extension direction of the metal sheet joint in the flow channel is consistent with the extension direction of the flow channel. By magnetically adsorbing the magnetized nozzle 2 onto the flow channel, it can be ensured that the movement trajectory of the nozzle 2 is consistent with the extension direction of the metal sheet joint during the glue application process, thereby improving the uniformity of the glue application. This prevents insufficient glue from affecting the sealing performance and avoids excessive glue from interfering with the installation of subsequent components.

[0032] It should be understood that the water tank in this embodiment includes a bottom wall and two side walls, the two side walls being located on the same side of the bottom wall and spaced apart in a direction parallel to the bottom wall. That is, the space enclosed by the two side walls and the bottom wall is the internal space of the water tank.

[0033] See Figure 1 , Figure 1This is a schematic diagram of a glue gun assembly provided in an embodiment of this application. The glue gun assembly includes a glue gun body and a magnetic component 3. The glue gun body includes a fixing structure 1 and a nozzle 2 connected to the fixing structure 1. The fixing structure 1 is used to fix the glue bottle, and the nozzle 2 is used to allow the glue in the glue bottle to flow out into a flow tank. The magnetic component 3 is connected to the glue gun body and is used to magnetize the nozzle 2 so that the nozzle 2 can be attracted to the inner wall of the flow tank.

[0034] In the above scheme, a magnetic component 3 is connected to the glue gun body, and the nozzle 2 is magnetized by the magnetic component 3, making the nozzle 2 magnetic. Thus, during the glue application process on the water tank, the nozzle 2 can magnetically adhere to the inner wall of the water tank. Due to the magnetic attraction between the nozzle 2 and the inner wall of the water tank, the glue gun remains in close contact with the inner wall during the glue application process. This ensures that the movement trajectory of the glue gun aligns with the extension direction of the joints between the metal plates within the water tank, improving the uniformity of glue application within the water tank. This prevents insufficient glue from affecting sealing performance and avoids excessive glue from interfering with the installation of subsequent components.

[0035] In some examples, the magnetic component 3 can be connected to the fixing structure 1 of the glue gun body. The magnetic component 3 is connected to the nozzle 2 via a magnetically conductive material to magnetize the nozzle 2. For example, an iron wire can be connected between the magnetic component 3 and the nozzle 2, with one end of the wire connected to the magnetic component 3 and the other end connected to the nozzle 2. If the fixing structure 1 of the glue gun body is made of a magnetically conductive material, the magnetic component 3 can also be directly connected to the glue gun body.

[0036] In other examples, the magnetic component 3 can be attached to the nozzle 2.

[0037] In some examples, the magnetic component 3 can be connected to the fixed structure 1 or the nozzle 2 by means of embedding, bonding, or magnetic adsorption.

[0038] It should be understood that in the embodiments of this application, the nozzle 2 is magnetized by the magnetic component 3, which can magnetize the entire nozzle 2 or only a part of the nozzle 2. The purpose is to make the nozzle 2 magnetically adsorbed to the inner wall of the vehicle's water channel after magnetization.

[0039] In addition, the fixing structure 1 of the glue gun body in this embodiment is used to fix the glue bottle. For example, the fixing structure 1 can be a cylindrical structure to fix the glue bottle inside the cylindrical structure; or it can be a clamping structure to clamp and fix the glue bottle. The fixing structure 1 can also refer to the specific structure of the glue gun for fixing the glue bottle. This application does not limit the structure of the fixing structure 1 of the glue gun body.

[0040] In some embodiments, the nozzle 2 is a magnetically conductive metal structure. In this way, after the magnetic component 3 magnetizes the nozzle 2, the entire nozzle 2 becomes magnetic, allowing it to magnetically attract the water tank at different positions, thus improving the flexibility of using the glue gun.

[0041] In some examples, the nozzle 2 is made of iron. After being magnetized by the magnetic component 3, the iron becomes magnetic and can be magnetically attracted to the inner wall of the water tank.

[0042] In some other embodiments, the nozzle 2 of the glue gun is made of plastic, and magnetic material is wrapped around or embedded on the outer periphery of the nozzle 2.

[0043] In some implementations, see Figure 2 and Figure 3 The nozzle 2 has a flat structure, and the magnetic component 3 is located on one side of the nozzle 2 along its thickness direction. Making the nozzle 2 flat, compared to a conical nozzle 2, makes it easier to connect with the magnetic component 3. Directly placing the magnetic component 3 on the nozzle 2 shortens the distance between the magnetic component 3 and the water tank, enhancing the magnetic attraction between the nozzle 2 and the water tank, and preventing the nozzle 2 from detaching from the water tank during the adhesive application process.

[0044] In addition, designing nozzle 2 as a flat structure allows the adhesive to flow out evenly in a ribbon-like pattern, avoiding the uneven adhesive distribution that may occur with round nozzles and reducing the risk of cracking after the adhesive cures. Furthermore, the flat nozzle structure increases the contact area with the flow channel, making the nozzle slide more smoothly along the flow channel.

[0045] In some examples, the nozzle 2 is made of a magnetic material, and the magnetic component 3 is magnetically adsorbed onto one side surface of the nozzle 2 in the thickness direction.

[0046] In other examples, a portion of the magnetic component 3 is embedded in one side surface of the nozzle 2 in the thickness direction, thereby improving the stability of the connection between the magnetic component 3 and the nozzle 2.

[0047] In some other examples, the magnetic component 3 is bonded to one side surface of the nozzle 2 in the thickness direction. For example, the magnetic component 3 can be bonded to the nozzle 2 using structural adhesive or double-sided tape.

[0048] In some embodiments, the magnetic component 3 is either a permanent magnet or an electromagnet. The ability of the magnetic component 3 to be either a permanent magnet or an electromagnet enhances the flexibility of the glue gun assembly setup.

[0049] In some examples, the magnetic component 3 is a permanent magnet that can be directly magnetically attached to one side of the nozzle 2 in the thickness direction. It has the advantages of small size and light weight, and can avoid collision between the magnetic component 3 and the water tank during the glue application process.

[0050] In some examples, the magnetic component 3 is an electromagnet. The circuitry of the electromagnet can be incorporated into the fixing structure 1 of the glue gun body. The electromagnet exhibits good stability in magnetic strength, preventing magnetic attenuation over prolonged use.

[0051] In some implementations, see Figures 1-4 The glue gun assembly also includes an anti-wear component 4, which is located on the nozzle 2 and is used to contact the bottom wall of the water tank. By providing the anti-wear component 4 to the nozzle 2 and having it contact the bottom wall of the water tank, wear on the nozzle 2 can be prevented during use, thus extending the service life of the nozzle 2.

[0052] In some examples, the wear-resistant component 4 is a metal gasket. Metal gaskets have good wear resistance and do not require frequent replacement. Furthermore, during the sliding process of the metal gasket in contact with the bottom wall of the water tank, the friction process gradually increases the smoothness of its surface, improving the smoothness of the metal gasket sliding along the water tank.

[0053] In addition, the metal pad can be made of a magnetic material. In this way, the magnetic component 3 can magnetize the metal pad, so that it generates a magnetic attraction force with the bottom wall of the water tank, preventing the nozzle 2 from separating from the bottom wall of the water tank during the glue application process, improving the stability of the nozzle 2 sliding along the water tank, and thus improving the glue application quality.

[0054] In other examples, the wear-resistant component 4 can be made of rubber or resin, etc.

[0055] In some examples, the magnetic component 3 and the anti-wear component 4 are located on the same side in the thickness direction of the nozzle 2.

[0056] In other examples, the magnetic component 3 and the anti-wear component 4 are respectively disposed on both sides of the nozzle 2 in the thickness direction.

[0057] In some implementations, see Figure 3 The surface where the glue outlet 21 of the nozzle 2 is located is the first surface 22. The connection between the first surface 22 and the surface where the anti-wear component 4 is located is the contact portion 23. The contact portion 23 is used to contact the bottom wall of the water tank, and at least a portion of the anti-wear component 4 covers the contact portion 23. Since the glue gun may be tilted during the glue application process, forming a certain angle with the bottom wall of the water tank, the nozzle 2 contacts the bottom wall of the water tank through the contact portion 23. Covering at least a portion of the anti-wear component 4 with the contact portion 23 of the nozzle 2 can prevent wear on the contact portion 23 when the glue gun slides along the water tank in an tilted state, thus extending the service life of the nozzle 2.

[0058] In some examples, the contact portion 23 of the nozzle 2 is the edge where the first surface 22 transitions to the surface where the abrasion-resistant component 4 is located.

[0059] In other examples, the contact portion 23 of the nozzle 2 is a slope or arc surface, that is, the first surface 22 and the surface where the wear-resistant part 4 is located are transitioned by a slope or arc surface.

[0060] In some implementations, see Figure 2, Figure 3 The nozzle 2 has a flat structure, and its first surface 22 includes an arc-shaped surface. Along a first direction, the arc-shaped surface has a first end 221 and a second end 222. The first direction is perpendicular to the thickness direction of the nozzle 2 and perpendicular to the arrangement direction of the fixed structure 1 and the nozzle 2. The first end 221 is closer to the fixed structure 1 than the second end 222. By setting the first surface 22 of the flat nozzle 2 to an arc-shaped surface, and with the first end 221 of the arc-shaped surface being closer to the fixed structure 1 than the second end 222 along the first direction, the gap between the nozzle 2 and the corner area of ​​the water trough can be eliminated, allowing the colloid to cover the corner area of ​​the water trough and improving the sealing performance of the water trough.

[0061] In other embodiments, the nozzle 2 has a flat structure and the first surface 22 is a plane.

[0062] In some embodiments, the wear-resistant component 4 is bonded to the nozzle 2. This facilitates the replacement of the wear-resistant component 4.

[0063] In some examples, the abrasion protection component 4 can be bonded to the nozzle with structural adhesive.

[0064] In other embodiments, the wear-resistant component 4 can be connected to the nozzle by means of riveting, welding, or other methods.

[0065] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0066] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto.
