Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing, and in particular relates to a glue application gun nozzle for automobile manufacturing. Background Technology

[0002] In the process of automobile production, various sealants, adhesives and other liquid materials need to be applied. Many parts need to be bonded, especially with the use of lightweight materials (such as aluminum alloys, carbon fiber and so on). At the same time, in order to reduce the noise during vehicle operation, glue gun nozzles are used to apply materials such as sound insulation glue and damping glue, which are commonly found in car door linings, floors, ceilings and other places, playing a role in sound absorption and vibration reduction.

[0003] In the prior art, the shape of the glue application nozzle varies in different application scenarios. In order to improve the utilization rate of the device, the glue application nozzle is often replaced so that the glue application device can be used in different working scenarios. However, during the replacement and installation of the glue application nozzle, glue overflow often occurs due to improper installation by the operator. At the same time, during the replacement of the glue application nozzle, the glue may be sprayed out before the glue application nozzle is installed in the designated position due to accidental touch by the operator.

[0046] Connecting pipe 1, one end of which is connected to the glue supply pipeline, and the other end of which is connected to the inlet end of the glue application nozzle 5;

[0049] Limiting component 4 is used to limit the movement of the driving component.

[0050] A rotating shaft 201 is fixedly mounted on the circular baffle 2. The axis of the rotating shaft 201 coincides with the center of the circular baffle 2, and the axis of the rotating shaft 201 is parallel to the end face of the circular baffle 2.

[0051] The side wall of the connecting pipe 1 has a rotating hole 101 that matches the rotating shaft 201, and the rotating shaft 201 is located inside the rotating hole 101.

[0052] The sidewall of the circular baffle 2 is curved and fits against the inner sidewall of the connecting pipe 1.

[0053] The control component 3 includes:

[0054] Sleeve 301, wherein sleeve 301 is disposed on the outside of connecting pipe 1;

[0055] Gear 302, which is fixedly connected to both ends of rotating shaft 201, and the axis of gear 302 coincides with the axis of transmission shaft;

[0056] Rack 303 is fixed on the inner wall of sleeve 301 and meshes with gear 302.

[0057] A limiting groove 102 is formed on the outer wall of the connecting pipe 1, and the limiting groove 102 includes:

[0058] The longitudinal section has its top end penetrating the outer wall of the connecting pipe 1 and its bottom end located inside the connecting pipe 1.

[0059] The transverse portion has one end connected to the longitudinal portion and the other end passing through the connecting pipe 1 and forming an opening at the end of the connecting pipe 1 near the adhesive nozzle 5.

[0060] The limiting component 4 is located inside the limiting groove 102, and the limiting component 4 includes:

[0061] The limiting block 401 is located inside the longitudinal part. A trapezoidal block 403 is provided on the part of the limiting block 401 near the bottom of the longitudinal part. The top surface of the limiting block 401 and the trapezoidal block 403 are fixedly connected. A compression spring is fixed between the bottom surface of the trapezoidal block 403 and the bottom surface of the longitudinal part.

[0062] The drive rod 402 is located inside the transverse portion. One end of the drive rod 402 near the longitudinal portion has an inclined surface corresponding to the trapezoidal block 403. The inclined surface of the drive rod 402 is in contact with the inclined surface of the limiting block 401.

[0063] The sidewall of the circular baffle 2 is an arc surface with a diameter equal to the inner diameter of the connecting pipe 1.

[0064] A semi-circular slider 202 is fixed on the rotating shaft 201. An annular groove 103 matching the semi-circular slider 202 is opened on the outer wall of the connecting pipe 1. The annular groove 103 is a 3 / 4 circle. The semi-circular slider 202 is located inside the annular groove 103.

[0065] A fixing bolt is threaded onto the sleeve 301. The fixing bolt passes through the sleeve 301 and abuts against the outer wall of the connecting pipe 1.

[0066] Work process:

[0067] When it is necessary to replace or install the glue application nozzle 5, the glue application nozzle 5 must be installed on the connecting pipe 1 and in place before the glue spraying work can begin.

[0068] Before the glue nozzle 5 is installed into the connecting pipe 1, the circular baffle 2 inside the connecting pipe 1 is vertical. The circular baffle 2 blocks the glue in the part of the connecting pipe 1 away from the glue nozzle 5. At this time, the limiting block 401 is located outside the limiting groove 102 under the support of the compression spring. The inclined surface of the drive rod 402 is only partially in contact with the inclined surface of the trapezoidal block 403. The end of the drive rod 402 away from the longitudinal part is located outside the transverse part. The side wall of the limiting block 401 presses against the end of the sleeve 301 near the glue nozzle 5, causing the sleeve 301 to be unable to move, which in turn causes the circular baffle 2 to be unable to rotate.

[0069] When the adhesive nozzle 5 is installed in place, it presses against the drive rod 402, causing the drive rod 402 to move along the transverse opening direction. At this time, the inclined surface of the drive rod 402 applies a downward force to the inclined surface of the trapezoidal block 403. The trapezoidal block 403 moves longitudinally under the restriction of the longitudinal part, the compression spring is compressed, and the limiting block 401 moves with the trapezoidal block 403 until it is completely retracted into the limiting groove 102. The sleeve 301 can move axially. During the movement of the sleeve 301, its interior... The rack 303 drives the gear 302 to rotate, and the gear 302 further drives the circular baffle 2 to rotate until the circular baffle 2 is completely horizontal. During this process, the annular groove 103, which is a 3 / 4 ring, and the semi-circular slider 202 cooperate with each other to limit the rotation angle of the circular baffle 2, so that the circular baffle 2 will not cause obstruction or incomplete release due to excessive rotation. When the sleeve 301 is moved to the point where it can no longer be pushed, the fixing bolt is rotated until the fixing bolt is tightened against the connecting pipe 1, thereby preventing the sleeve 301 from retracting.

[0070] This device and its workflow ensure that glue spraying can only begin when the glue nozzle 5 is installed on the connecting pipe 1 and in place. This prevents glue overflow caused by improper installation of the glue nozzle 5 during installation. At the same time, it avoids the problem of glue being sprayed out before the glue nozzle 5 is fully installed due to accidental activation of the glue spraying device switch during the installation of the glue nozzle 5.
