Description

Technical Field

[0001] The utility model relates to the technical field of gluing, and specifically relates to a gluing device for an inner plate of a door sill of an automobile. Background Art

[0002] The car door is the window of the whole vehicle and also the biggest inlet of wind noise. In order to block the noise, it is necessary to use door film on the car. The car door film is required to be able to adhere precisely to the designated position of the car door, which requires gluing at the bonding position of the door. There are many ways to apply glue, which can be manual gluing, pneumatic gluing or robotic gluing, but the gluing process requires certain devices to fix the car door and then implement the gluing.

[0003] There are two traditional gluing methods, one is manual gluing and the other is robot gluing. The robot gluing process is repeated. After the gluing of the car door is completed, the glue at the end of the glue outlet pipe is separated from the glue applied on the car door, and glue overflows from the end of the glue outlet pipe. The glue will drip when the robot moves. Therefore, a device is needed to absorb the glue overflowing from the glue outlet pipe back into the glue outlet pipe. A car door sill inner panel gluing device is specially proposed. Utility Model Content

[0004] The utility model aims to provide a device for coating glue on the inner plate of a vehicle threshold, so as to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the adsorption device includes a sleeve, which is mounted on the rubber outlet pipe, a rubber sleeve is installed in the middle of the sleeve, and the rubber sleeve blocks the through hole, the rubber sleeve and the sleeve form a sealed cavity, an air guide tube is installed on the outer wall of the sleeve, and the air guide tube is connected to an external air pump.

[0007] Preferably, the middle portion of the sleeve is arched outwards.

[0008] Preferably, annular limiting grooves are provided on both sides of the sleeve, and fasteners are provided in the annular limiting grooves, and the sleeve is fixed to the rubber outlet hose through the fasteners.

[0009] Preferably, the glue outlet of the glue outlet pipe is in an open shape.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: a device for coating glue on the inner panel of a car door sill, which can absorb a small amount of glue overflowing from the end of the glue outlet pipe after coating the car door with glue through an adsorption device arranged on the glue outlet pipe, thereby reducing glue dripping and increasing the utilization rate of the glue. The adsorption device adsorbs the glue overflowing from the end of the glue outlet pipe into a chamber formed between the rubber sleeve and the glue outlet pipe through a through hole for temporary storage. When coating the next car door with glue, the temporarily stored glue is pushed into the glue outlet pipe through the through hole by the adsorption device for reuse.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 The utility model provides a technical solution: a glue coating device for an inner panel of a vehicle threshold, comprising a glue outlet pipe 1, the outer side wall of the glue outlet pipe 1 is provided with a through hole 2, the outer side wall of the glue outlet pipe 1 is installed with an adsorption device wrapping the through hole 2, and the glue overflowing from the end of the glue outlet pipe 1 is adsorbed back to the inside through the through hole 2.

[0017] Specifically, the adsorption device includes a sleeve 3, which is sleeved on the rubber outlet pipe 1. A rubber sleeve 4 is installed in the middle of the sleeve 3, and the rubber sleeve 4 blocks the through hole 2. The rubber sleeve 4 and the sleeve 3 form a sealed cavity 5. An air guide tube 6 is installed on the outer wall of the sleeve 3, and the air guide tube 6 is connected to an external air pump.

[0018] The positive pressure or negative pressure in the sealing chamber 5 is controlled by an external air pump. The positive pressure state in the sealing chamber 5 makes the rubber sleeve 4 fit tightly with the surface of the rubber outlet pipe 1, and the rubber sleeve 4 blocks the through hole 2. The sealing chamber 5 is in a negative pressure state, the sealing chamber 5 is reduced, and the rubber sleeve 4 stretches outward. The rubber in the rubber outlet pipe 1 enters from the through hole 2, and the rubber overflowing from the rubber outlet pipe 1 is adsorbed.

[0019] Specifically, the middle portion of the sleeve 3 is arched outwards to increase the space of the sealing cavity 5 .

[0020] Specifically, annular limiting grooves 7 are formed on both sides of the sleeve 3 , and fasteners 8 are provided in the annular limiting grooves 7 , and the sleeve 3 is fixed to the rubber outlet hose 1 through the fasteners 8 .

[0021] Specifically, the glue outlet of the glue outlet pipe 1 is in an open shape, which increases the contact area between the glue and the end of the glue outlet pipe 1 and also facilitates the glue to enter the glue outlet pipe 1 when the adsorption device adsorbs the glue.

[0022] Working principle: When the utility model is used, during the gluing process, the air pump inflates the sealing cavity 5 through the air guide tube 6 to form a positive pressure. At this time, the rubber sleeve 4 fits tightly with the rubber outlet pipe 1 to block the through hole 2. After the gluing of the car door is completed, the rubber outlet pipe 1 leaves the gluing position and the glue will stick. At this time, the air pump is controlled to suck the gas in the sealing cavity 5 to drive the rubber sleeve 4 to deform, and the glue in the rubber outlet pipe 1 is sucked in from the through hole 2, and a small amount of glue overflowing from the rubber outlet pipe 1 is sucked in there, reducing the dripping of glue. When gluing again, the air pump is used to inflate the sealing cavity 5, so that the rubber sleeve 4 pushes the glue from the through hole 2 into the rubber outlet pipe 1 for reuse.

[0023] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
