Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle applications, in particular to a new energy vehicle door weld sealant gun nozzle. Background Art

[0002] Door weld sealant is a sealant used in the welding parts of doors and other parts during the automobile manufacturing process. Its main function is to enhance the sealing, shockproof and noise reduction of the car body and improve the comfort of the whole vehicle.

[0003] The traditional weld sealant gun nozzle is a flat shape. For locations with high requirements on the appearance, such as car doors and front and rear covers, the glue application is required to be flat and smooth without obvious glue bubbles. However, the traditional glue gun nozzle is prone to obvious glue bubbles on the glue surface after glue application. The main reason is that after the sealant is baked in the drying room, air is discharged from the weld, which lifts up the sealant close to the sheet metal surface, resulting in obvious glue bubbles. To address the glue bubble problem, the main manufacturers currently use thumb glue to repair it, which causes waste of manufacturing costs and increased labor, and affects the production rhythm. The position of the glue bubble after repair cannot 100% overlap with the original glue strip, and the glue application quality is reduced. To this end, the utility model proposes a new energy vehicle door weld sealant gun nozzle. Utility Model Content

By changing the plane shape of the glue gun nozzle, from a two-sided flat shape to a groove design, after the new shape glue gun nozzle is glued on the vehicle door, a channel will be left in the middle of the glue strip due to the groove design. When it is baked in the drying room, the gas in the weld is discharged and remains in the channel, and the sealant cannot be pushed out to cause the formation of glue bubbles. The gas in the channel will slowly be discharged through the gap of the sealant, and the sealant will be leveled and adhered to the sheet metal surface. The overall glue strip is flat and smooth without glue bubbles.

[0009] Through the above technical solution, it is convenient for workers to hold and fix the glue gun rod through the protective cover during operation, and the anti-slip strip can prevent it from sliding during movement, thereby improving the stability of the glue discharging operation.

[0011] Through the above technical solution, when gluing the door weld, the staff can use the auxiliary rod and spring to protect and stabilize the glue gun rod in a stable position, making it convenient for the glue nozzle to fit and remove glue from the door weld.

[0012] The utility model is further configured as follows: the inner wall of the sliding sleeve is slidably connected to the outer wall of the glue gun rod, and is tightly arranged with the limiting sleeve B under the elastic action of the spring.

[0013] Through the above technical solution, the sliding sleeve can slide stably on the glue gun rod when it is squeezed, and the sliding sleeve can be limited and fixed under the action of the limiting sleeve.

[0014] The utility model is further configured as follows: the spring is wrapped around the outer wall of the glue gun rod, and the end surface away from the sliding sleeve is tightly arranged against the limiting sleeve A.

[0015] The above technical solution facilitates the positioning and fixing of the bottom end face of the spring and facilitates the stable compression setting of the spring.

[0017] Through the above technical solution, when discharging glue, the protective part can be used to limit the glue discharged from the glue discharging part to prevent the glue position from shifting, and the groove design is adopted so that the extruded glue strip passes through the limit of the channel convex strip, and a channel is left in the middle of the glue strip. The gas in the channel will slowly be discharged through the gap of the sealant, and the sealant will flow levelly and adhere to the sheet metal surface. The whole glue strip is flat and smooth without glue bubbles.
