Description

Technical Field

[0001] This utility model belongs to the field of automotive body adhesive application technology, specifically relating to an adhesive nozzle and adhesive application device for applying adhesive to the overlapping seams of automotive body skin. Background Technology

[0002] The body panels are the surface coverings on the vehicle's frame. The overlaps between these panels are fixed to the frame via spot welding or riveting. Taking the roof panel as an example, it consists of side panels and a center panel, with the center panel overlapping the side panels. Both are then fixed to the roof frame via spot welding or riveting. According to process requirements, sealant needs to be applied to the seams at the panel overlaps. The current standard procedure involves cleaning the overlap area, applying masking tape to both sides of the seam, applying and scraping the sealant along the seam, removing the masking tape, and finally trimming the edges and surface of the sealant strip. This process is cumbersome, time-consuming, and inefficient, and results in sealant waste due to residue on the scraper and masking tape. In addition, high-concentration soapy water is usually used when repairing rubber strips. After repair, soapy water is easily left on the body skin. The residual soapy water has a significant impact on the adhesion of the paint, which can easily cause problems such as rough paint, blistering, and peeling of the body skin. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a glue nozzle and glue application device for the overlapping seams of car body panels, which aims to complete the glue application process of the required glue strips in one go, reduce the difficulty of glue application, simplify the glue application process, improve glue application efficiency, reduce the waste of sealant, and improve the problems of roughness, bubbling and peeling of car body panel paint caused by residual soap water.

[0004] This utility model provides a glue nozzle for applying sealant to the overlapping seam of a car body panel. The nozzle body is hollow and has two through-holes. One end of the nozzle body is used to connect directly or indirectly to a glue gun, while the other end is flat, forming a flat end. An arc-shaped groove is provided on one long side of the flat end face of the nozzle body, forming an arched glue outlet on one side of the flat end face. A positioning pin is provided on the side of the flat end face corresponding to the other long side. The positioning pin is used to position the nozzle body along the overlapping seam when it moves perpendicular to the overlapping seam of the car body panel.

[0005] Furthermore, the bottom width of the arched dispensing nozzle is the same as the long side dimension of the flat end of the nozzle body.

[0006] Furthermore, the flat end face of the nozzle body is provided with two baffles, which are located at opposite ends of the end face along its length. The area between the two baffles forms a through area of ​​the flat end of the nozzle body, and the bottom width of the arched dispensing port is the same as the distance between the two baffles.

[0007] Furthermore, the positioning pin is offset from the centerline of the flat end of the nozzle body.

[0008] Furthermore, the nozzle body is integrally provided with a connecting tube at one end, either directly or connected to the glue gun.

[0009] Furthermore, it also includes a mounting base for fixing to the glue gun, and the connecting tube is connected to the mounting base.

[0010] Furthermore, the mounting base and the connecting hose are detachably connected.

[0011] Furthermore, the mounting base is provided with a second connecting hose, which is threadedly connected to the first connecting hose.

[0012] The present invention also provides a device for applying glue to the overlapping seams of vehicle body panels, including a glue gun and a glue nozzle as described above.

[0013] Furthermore, the glue gun can be any one of a manual glue gun, a pneumatic glue gun, or an electric glue gun.

[0014] The beneficial effects of this utility model are that, during the glue application process, by placing the positioning pin against the overlap seam, it can be ensured that the glue nozzle body does not deviate from the overlap seam, but always applies glue along the length direction of the overlap seam. Furthermore, the shape of the arched glue outlet can directly simulate the cross-sectional shape of the molded glue strip. As the glue nozzle body moves, it directly utilizes the through area of ​​the flat end face and the arched glue outlet on one side to apply the required glue strip, which is straight, covers the overlap seam, has a consistent width, an arc-shaped surface, and an arch-like cross-section, along the length direction of the overlap seam. This combines the glue application and scraping actions into one, completing the glue application process in one go. It eliminates the need for applying masking tape and secondary trimming of the glue strip, reducing the difficulty of glue application, simplifying the process, and improving efficiency. It also reduces sealant waste and lowers costs. Moreover, by eliminating the secondary trimming process, it also improves the problem of roughness, bubbling, and peeling of the car body paint caused by residual soap water, reducing the amount of paint rework.

[0021] like Figures 1-5 As shown, this utility model provides a glue nozzle for applying sealant to the overlapping seam of a car body panel. The nozzle body 1 is hollow and has two through-holes. One end of the nozzle body 1 is used to connect directly or indirectly to a glue gun, while the other end is flat, forming a flat end. Because this end of the nozzle body 1 is flat, its end face has two long sides. One of the long sides has an arc-shaped groove, forming an arched glue outlet 11. This arched glue outlet 11 is specifically located on one side of the flat end face of the nozzle body 1. A positioning pin 2 is provided on the side of the flat end of the nozzle body 1 corresponding to the other long side. That is, the positioning pin 2 and the arched glue outlet 11 are located on different sides of the flat end of the nozzle body 1. The positioning pin 2 is used to position the nozzle body 1 along the overlapping seam 300 when it moves perpendicular to the overlapping seam of the car body panel. Among them, the body panel overlap is the overlap of two panels, and the overlap seam 300 is the gap at the edge of the overlap of the two panels. When applied to the roof panel, the two overlapping panels are the top center panel 100 and the top side panel 200.

[0022] When applying sealant to the overlapping seam 300 of the skin using this invention, the flat end face of the nozzle body 1 contacts the overlapping area of ​​the skin, and the nozzle body 1 is perpendicular to the overlapping area of ​​the body skin. The sealant is applied along the arched outlet 11 on one side of the flat end of the nozzle body 1, maintaining the perpendicularity and contact between the nozzle body 1 and the overlapping area of ​​the skin. The nozzle body 1 is moved along the length direction of the overlapping seam 300. During the application process, by placing the positioning pin 2 against the overlapping seam 300, the positioning of the positioning pin 2 can ensure that the nozzle body 1 does not deviate from the overlapping seam 300, but always applies sealant along the length direction of the overlapping seam 300. Furthermore, the shape of the arched glue outlet 11 can directly simulate the cross-sectional shape of the molded glue strip. As the glue nozzle body 1 moves, the through area of ​​the flat end face and the arched glue outlet 11 on one side are used to directly apply the required glue strip that is straight, covers the overlap edge 300, has a consistent width, an arc-shaped surface, and an arch-shaped cross-section along the length of the overlap edge 300. This combines the glue application and scraping actions into one, completing the glue application process in one go. It eliminates the need for pasting masking tape and performing secondary adjustments to the glue strip in the original glue application process. This reduces the difficulty of glue application, simplifies the glue application process, and improves glue application efficiency. At the same time, it also reduces the waste of sealant and lowers costs. Moreover, since the secondary adjustment process is eliminated, it also improves the problems of roughness, bubbling, and peeling of the paint on the car body skin caused by residual soap water, reducing the amount of paint rework.

[0023] The width of the bottom of the arched glue outlet 11 is the width of the arched glue outlet 11 at... Figure 1 or Figure 3 The dimension in the lateral direction is also the length direction of the long side of the flat end face of the nozzle body 1. Figure 1 or Figure 3 Dimensions in the lateral direction.

[0024] In one embodiment of this invention, the two long sides and two short sides of the flat end face of the nozzle body 1 are perpendicular to each other. In this embodiment, the bottom width of the arched dispensing port 11 is the same as the length of the long side of the flat end of the nozzle body 1.

[0025] In another embodiment of this invention, due to limitations in the molding process, the two short sides of the flat end face of the nozzle body 1 are arc-shaped. In this embodiment, two baffles 12 are provided on the flat end face of the nozzle body 1. The two baffles 12 are located at opposite ends along the length of the end face, closing off the arc-shaped area where the short sides are located. That is, the area between the two baffles 12 on the flat end face of the nozzle body 1 forms the through area of ​​the flat end of the nozzle body 1. The bottom width of the arched dispensing port 11 is the same as the distance between the two baffles 12, so that the arched dispensing port 11 avoids the arc-shaped area of ​​the flat end.

[0026] The end of the positioning pin 2 may slightly protrude from the flat end face of the nozzle body 1, ensuring that the positioning pin 2 can rest against the overlap seam 300 during glue application. In this utility model, it is preferable that the positioning pin 2 is offset from the centerline of the flat end of the nozzle body 1, such as... Figure 4 and Figure 5 As shown, the through area of ​​the flat end face of the nozzle body 1 and the arched dispensing port 11 can cover the riveting position of the two skins, so that the applied sealant simultaneously covers the overlapping seam 300 and the rivet. In other configurations of this utility model, the positioning pin 2 can also be centrally located on one side of the flat end of the nozzle body 1.

[0027] In one embodiment of this invention, one end of the nozzle body 1 is directly fixed to the glue gun, thereby directly connecting it to the glue gun.

[0028] In a preferred embodiment of this invention, the nozzle body 1 is integrally provided with a connecting tube 3 at one end, either directly or connected to the glue gun; that is, the nozzle body 1 and the connecting tube 3 are a single unit. The connecting tube 3 facilitates the connection between the nozzle body 1 and the glue gun, and also makes it easier to use other connection methods. Specifically, this invention also includes a mounting base 4 for fixing to the glue gun. The mounting base 4 is annular and is sleeved and fixed to the glue outlet end of the glue gun. The structure of the mounting base 4 is the same as that of the mounting base of the nozzle in the prior art, and the method of fixing it to the glue gun is also the same as in the prior art. The connecting tube 3 is connected to the mounting base 4, thereby achieving an indirect connection between the nozzle body 1 and the glue gun.

[0029] The mounting base 4 and the connecting tube 3 are detachably connected to facilitate the replacement of the nozzle body 1 with different arc-shaped dispensing nozzles 11, adapting to the cross-sectional shape requirements of the adhesive strip in different situations. Specifically, a connecting tube 5 is integrally provided on one end of the mounting base 4, meaning that the connecting tube 5 and the mounting base 4 are a single piece. The outer side of the connecting tube 5 has external threads, and the inner side of the connecting tube 3 has internal threads. The connecting tube 5 and the connecting tube 3 are threaded together, thus achieving a detachable connection between the mounting base 4 and the connecting tube 3. This connection method is simple, stable, and easy to disassemble. During adhesive application, the sealant in the glue gun enters the nozzle body 1 from its dispensing end along the connecting tube 5 and the connecting tube 3, and exits from the through area of ​​the flat end face of the nozzle body 1 and the arc-shaped dispensing nozzle 11.

[0030] This utility model also provides a device for applying sealant to the overlapping seams of car body panels. This device includes a glue gun and a sealant nozzle as described above. Due to the presence of the sealant nozzle, a straight strip of sealant, uniform in width, with an arc-shaped surface and an arch-like cross-section, can be applied along the length of the overlapping seam 300mm. This combines the application and scraping of sealant into a single process, eliminating the need for masking tape and secondary trimming of the sealant strip. This simplifies the application process, improves efficiency, reduces sealant waste, and lowers costs. Furthermore, by eliminating the secondary trimming process, it also mitigates issues such as roughness, bubbling, and peeling of the car body panel paint caused by residual soapy water, reducing the amount of paint rework.

[0031] The glue gun can be any one of a manual glue gun, a pneumatic glue gun, or an electric glue gun. In specific applications, the appropriate glue gun can be selected according to actual needs.
