Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle application technology, and in particular to a guide glue gun nozzle for welding seams in new energy vehicles. Background Technology

[0002] In the production and manufacturing process of new energy vehicles, the weld sealing operation is a key process to ensure the vehicle body's sealing performance, waterproofing, and structural stability.

[0003] Traditional glue gun nozzles often suffer from two major problems when applying glue to weld seams: First, they lack a stable guiding structure, making it easy for the glue line to deviate from the center of the weld seam due to hand tremors or operational deviations during the application process, resulting in glue leakage, glue breakage, or uneven glue layer, requiring secondary glue application and increasing labor and material costs; Second, the connection between the glue nozzle and the glue gun has poor sealing performance, making it prone to glue leakage, and the fixed shape of the glue outlet cannot adapt to the glue application requirements of different models and different locations of weld seams (such as straight weld seams and corner weld seams) in new energy vehicles, resulting in inconsistent sealing effects and affecting the overall quality of the vehicle body.

[0004] Therefore, this utility model proposes a guide glue gun nozzle specifically for weld seams in new energy vehicles. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a special guide adhesive nozzle for weld seams of new energy vehicles. Through optimized structural design, it can achieve stable guidance during the adhesive application process, controllable adhesive dispensing pattern, and convenient disassembly and assembly of components, thereby improving the accuracy and efficiency of adhesive application to weld seams of new energy vehicles.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a special guide glue gun nozzle for weld seams of new energy vehicles, including a glue gun connecting part, wherein guide parts are symmetrically engaged on both sides of the glue gun connecting part to achieve stability of the entire glue dispensing process; One end of the glue gun connector is connected to an external glue gun, and the other end is threaded with a glue nozzle to fix the position of the glue nozzle and ensure that the sealant is dispensed in a certain shape.

[0007] The present invention is further configured such that: a connecting groove A for mounting to the end of the glue gun is provided on the inner wall of one end of the glue gun connecting part, and a connecting groove B is provided on the other end of the glue gun connecting part, and the glue nozzle is threadedly connected to the inner wall of the connecting groove B through a connecting ring fixedly connected to one end of the nozzle.

[0008] Through the above technical solution, the connecting groove A can form a precise fit with the end of the external glue gun, ensuring the coaxiality of the glue gun and the glue gun connection part, and avoiding resistance caused by radial offset of the glue during transmission; the threaded fit between the connecting groove B and the connecting ring can realize quick disassembly and assembly of the glue nozzle, making it easy to replace different specifications of glue nozzles according to the type of weld. On the other hand, the sealing of the threaded connection can prevent the glue from leaking from the connection. At the same time, the position of the glue nozzle can be finely adjusted by tightening the thread, further ensuring the alignment accuracy between the glue outlet and the weld.

[0009] The present invention is further configured such that: the guide portion includes mounting grooves on both sides of the glue gun connection portion; the inner wall of the mounting groove is inserted and engaged with a mounting shaft; the mounting shaft is hollow inside and is engaged with a spring piece inside; the spring piece engages the mounting shaft with the mounting groove; the end face of the mounting shaft is fixedly connected to a mounting plate; and a roller is rotatably connected to the mounting plate near the bottom.

[0010] Through the above technical solution, the mounting groove provides a positioning reference for the mounting shaft, and the elastic force of the spring can keep the mounting shaft and the mounting groove tightly engaged, preventing the guide from loosening during the glue application process; the support of the mounting plate for the roller can ensure that the roller is in contact with the weld surface. When applying glue, the roller rolls along the weld, converting sliding friction into rolling friction, reducing glue application resistance. At the same time, the symmetrical rollers on both sides form a "clamping" guide, limiting the lateral deviation of the glue gun nozzle, ensuring that the glue outlet is always aligned with the center of the weld, and achieving stable glue application.

[0011] The present invention is further configured such that: the spring piece is U-shaped, and positioning protrusions are fixedly connected to both sides of the outer wall near the end face, and the positioning protrusions pass through positioning holes B and positioning holes A opened on the mounting shaft and mounting groove in sequence.

[0012] Through the above technical solution, the U-shaped spring sheet has excellent elastic deformation capability. Pressing both ends of the spring sheet can cause the positioning protrusion to disengage from positioning hole A and positioning hole B, realizing the quick separation of the mounting shaft from the mounting groove, which facilitates the maintenance or replacement of the guide part. The cooperation between the positioning protrusion and the double positioning holes can form double positioning, preventing the mounting shaft from axially rotating or radially moving in the mounting groove, further improving the structural stability of the guide part, and ensuring that the guiding accuracy is not affected by the loosening of the components.

[0013] The present invention is further configured such that: the dispensing nozzle includes an operating block, and a hollow guide cavity is fixedly connected to one end of the operating block away from the connecting ring, and a dispensing port is fixedly connected to the end face of the guide cavity, and the two are connected.

[0014] Through the above technical solution, the operating block provides a force point for the operator to disassemble and assemble the dispensing nozzle, and facilitates the tightening and loosening of the threads between the connecting ring and the connecting groove B by rotating the operating block; the hollow guide cavity can buffer and guide the colloid, avoid the formation of air bubbles due to excessive flow rate or pressure fluctuations, and ensure that the colloid is evenly delivered to the dispensing port; the connection design between the guide cavity and the dispensing port can ensure a smooth colloid transmission path, reduce colloid residue, and facilitate the cleaning of the inside of the nozzle after dispensing, thus extending the service life of the components.

[0015] The present invention is further configured such that: both sides of the inner wall of the dispensing port are provided with arc-shaped portions, and the arc-shaped portions are curved from the outside to the inside.

[0016] Through the above technical solution, the curved part can change the flow trajectory of the adhesive in the outlet, reduce the frictional resistance between the adhesive and the inner wall of the outlet, and avoid the "stringing" phenomenon of the adhesive due to excessive resistance. At the same time, the curved part can make the adhesive form a smooth transition shape when it is dispensed, ensuring that the edge of the adhesive line is smooth, avoiding the accumulation of adhesive layer or gaps, and improving the appearance quality and sealing performance of the weld seal. It is especially suitable for adhesive application scenarios of welds with high appearance requirements, such as the outer surface of new energy vehicle bodies.

[0017] The present invention is further configured such that: an extension is fixedly connected to the top of the dispensing port, and the two sides of the extension are inclined, while a triangular protrusion is provided at the middle position.

[0018] Through the above technical solution, the inclined extension can form a "fitting guide" for the sheet metal parts on both sides of the weld. When applying adhesive, the extension slides against the surface of the sheet metal parts, further limiting the longitudinal displacement of the adhesive outlet and ensuring uniform adhesive line thickness. The triangular protrusion in the middle can play a "diversion" role in the adhesive during the application process, so that the adhesive fills the weld gap more evenly and avoids insufficient adhesive filling due to uneven weld depth. It is especially suitable for sealing deep welds of structural components such as new energy vehicle frames, improving the structural strength and waterproof sealing of the weld.

[0019] The beneficial effects of this utility model are as follows: 1. The present invention proposes a special guide glue gun nozzle for weld seams of new energy vehicles. Through the symmetrical guide part design, the roller rolling guide and the spring positioning structure are used to achieve stable clamping and precise guidance in the glue application process. This effectively solves the glue application deviation problem of traditional glue gun nozzles, improves the accuracy and uniformity of glue line position, reduces the secondary glue replenishment process, and reduces production costs. 2. The present invention proposes a special guide adhesive nozzle for weld seams of new energy vehicles. The nozzle is connected by a thread and is replaceable. Combined with the optimized nozzle structure of the arc and extension, it can not only realize the quick disassembly and assembly of the nozzle and adapt to multiple scenarios, but also ensure that the adhesive dispensing pattern is controllable and the sealing effect is excellent. It can meet the adhesive application needs of different weld seam types of new energy vehicles and improve the manufacturing quality and production efficiency of the vehicle body.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] like Figures 1-4As shown, a special guide glue gun nozzle for weld seams in new energy vehicles includes a glue gun connecting part 1. One end of the glue gun connecting part 1 has a connecting groove A11 installed at the end of the glue gun, and the other end has a connecting groove B12. The glue nozzle 3 is threadedly connected to the inner wall of the connecting groove B12 through a connecting ring 32 fixedly connected to one end. The connecting groove A11 can form a precise fit with the external glue gun end, ensuring the coaxiality of the glue gun and the glue gun connecting part 1, and avoiding resistance caused by radial offset of the glue during transmission. The threaded engagement between the connecting groove B12 and the connecting ring 32 enables quick disassembly and assembly of the glue nozzle 3, facilitating the replacement of different specifications of glue nozzles according to the type of weld seam. On the other hand, the sealing of the threaded connection prevents the glue from leaking from the connection point. At the same time, the position of the glue nozzle can be finely adjusted by tightening the thread, further ensuring the alignment accuracy between the glue outlet 34 and the weld seam.

[0024] like Figure 4 and Figure 5 As shown, guide portions 2 are symmetrically engaged on both sides of the glue gun connection 1 to maintain stability throughout the glue dispensing process. The guide portions 2 include mounting grooves 21 on both sides of the glue gun connection 1. A mounting shaft 22 is inserted into the inner wall of the mounting groove 21 and engaged with it. The mounting shaft 22 is hollow inside and is engaged with a spring clip 23, which engages with the mounting shaft 22 in the mounting groove 21. A mounting plate 24 is fixedly connected to the end face of the mounting shaft 22. A roller 25 is rotatably connected to the mounting plate 24 near its bottom. The groove 21 provides a positioning reference for the mounting shaft 22. The elastic force of the spring piece 23 can keep the mounting shaft 22 and the mounting groove 21 tightly engaged, preventing the guide part 2 from loosening during the glue application process. The support of the mounting plate 24 for the roller 25 can ensure that the roller 25 is in contact with the weld surface. When applying glue, the roller 25 rolls along the weld, converting sliding friction into rolling friction, reducing the glue application resistance. At the same time, the symmetrical rollers 25 on both sides form a "clamping" guide, limiting the lateral deviation of the glue gun nozzle, ensuring that the glue outlet 34 is always aligned with the center of the weld, and achieving stable glue application. The spring piece 23 is U-shaped, and positioning protrusions 231 are fixedly connected to both sides of its outer wall near the end face. The positioning protrusions 231 pass through positioning holes B221 and A211 opened on the mounting shaft 22 and mounting groove 21 in sequence. The U-shaped spring piece 23 has excellent elastic deformation capability. Pressing both ends of the spring piece 23 can make the positioning protrusions 231 disengage from positioning holes A211 and B221, realizing the quick separation of the mounting shaft 22 from the mounting groove 21, which facilitates the maintenance or replacement of the guide part 2. The cooperation between the positioning protrusions 231 and the double positioning holes can form double positioning, preventing the mounting shaft 22 from axially rotating or radially moving in the mounting groove 21, further improving the structural stability of the guide part 2, and ensuring that the guiding accuracy is not affected by the loosening of the components.

[0025] like Figure 2and Figure 3 As shown, one end of the glue gun connecting part 1 is connected to an external glue gun, and the other end is threadedly connected to a glue nozzle 3 to fix the position of the glue nozzle 3 and ensure that the sealant is dispensed in a certain shape. The glue nozzle 3 includes an operating block 31. The end of the operating block 31 away from the connecting ring 32 is fixedly connected to a hollow guide cavity 33. The end face of the guide cavity 33 is fixedly connected to a glue outlet 34, and they are connected. The operating block 31 provides a force point for the operator to disassemble and assemble the glue nozzle 3, and it is convenient to tighten or loosen the threads of the connecting ring 32 and the connecting groove B12 by rotating the operating block 31. The hollow guide cavity 33 can buffer and guide the glue, avoid the glue from generating air bubbles due to excessive flow rate or pressure fluctuations, and ensure that the glue is evenly delivered to the glue outlet 34. The connection design between the guide cavity 33 and the glue outlet 34 can ensure a smooth glue transmission path, reduce glue residue, and facilitate cleaning of the inside of the glue nozzle after glue application, thus extending the service life of the components. Both sides of the inner wall of the dispensing port 34 are provided with arc-shaped portions 35, which are curved from the outside to the inside. The curved portions 35 can change the flow trajectory of the adhesive in the dispensing port 34, reduce the frictional resistance between the adhesive and the inner wall of the dispensing port, and prevent the adhesive from "stringing" due to excessive resistance. At the same time, the arc-shaped portions 35 can make the adhesive form a smooth transition shape when dispensing, ensuring that the edge of the adhesive line is smooth, avoiding adhesive layer accumulation or gaps, and improving the appearance quality and sealing performance of the weld seal. It is especially suitable for adhesive application scenarios for welds with high appearance requirements, such as the outer surface of new energy vehicle bodies. An extension 36 is fixedly connected to the top of the glue outlet 34, and the two sides of the extension 36 are inclined. At the same time, a triangular protrusion is provided in the middle. The inclined extension 36 can form a "fitting guide" for the sheet metal parts on both sides of the weld. When applying glue, the extension 36 slides against the surface of the sheet metal parts, further limiting the longitudinal displacement of the glue outlet 34 and ensuring uniform glue line thickness. The triangular protrusion in the middle can play a "diversion" role in the glue during the glue application process, so that the glue fills the gap of the weld more evenly, avoiding insufficient glue filling due to uneven weld depth. It is especially suitable for sealing deep welds of structural components such as new energy vehicle frames, improving the structural strength and waterproof sealing of the weld.

[0026] In use, this utility model first selects the appropriate dispensing nozzle 3 according to the type of weld seam in the new energy vehicle, such as straight weld seam or deep weld seam. By rotating the operating block 31, the connecting ring 32 is screwed into the connecting groove B12 to complete the installation of the dispensing nozzle 3. Then, the connecting groove A11 of the glue gun connecting part 1 is fitted and fixed to the end of the external glue gun to ensure the glue transmission channel is sealed. When applying glue, the roller 25 of the guide part 2 is placed against the surface of the sheet metal parts on both sides of the weld seam, and the extension part 36 is aligned with the center of the weld seam. The glue gun is pushed to move along the weld seam. The roller 25 rolls to achieve stable guidance. After the glue is buffered by the guide cavity 33, it forms a uniform glue line through the glue outlet 34 optimized by the arc part 35. The triangular protrusion ensures that the glue fully fills the gap of the weld seam. If the guide part 2 needs to be replaced, the spring piece 23 is pressed to make the positioning protrusion 231 dislodge from the positioning hole, and the mounting shaft 22 can be removed for replacement. The operation is convenient and efficient.
