Description

Vehicle door sealing strip pasting and installing system and pasting method

Technical Field

The invention relates to the field of automobile production auxiliary processing, in particular to a vehicle door sealing strip pasting and installing system and a pasting method using the vehicle door sealing strip pasting and installing system.

Background

The door weather strip is widely applied to various types of vehicles, and is mainly used for optimizing and improving the dustproof and noise-proof performance of the vehicle and the closing force of the door. At present, the sealing strip of the car door is mainly divided into a buckling type sealing strip and a pasting type sealing strip, wherein the pasting type sealing strip is more widely applied and has better effect, and particularly, the sealing strip is relatively high-end car models, such as popular car models, galloping car models, BMW (horse-shaped) car models, red flags and other car models. The adhesive door weatherstrip is attached to the door by pressing or rolling the weatherstrip with a special adhesive tape, such as the model number ST1200, 4112 of 3M company.

Because the door sealing strip looping type, main mounting means at present: firstly, adopt the manual work to place manual roll extrusion, the mounting means of this kind of form is difficult to guarantee to the installation accuracy, wastes time and energy. Secondly, a press disc type is adopted, the mode is an installation mode of most automobile manufacturers at present, the installation precision can be guaranteed, people are required to install the formed sealing strip in a matching mode, the manufacturing requirement on the early-stage sealing strip is high, the length, the precision and the cost of the sealing strip are guaranteed, the applicability and the universality are low, and the vehicle type applicability is limited. The two installation methods need personnel to be added, the automation degree is low, the adaptability is limited, and the adaptability is low.

Upon retrieval, chinese patent document CN101374632A discloses a method and system for applying a perimeter seal to an opening closure, in particular a motor vehicle door. The seal application process is completed in two stages. In a first stage, a seal cut to size from a continuous sealing strip is placed on a jaw placement and pressing element using a stationary rolling head, which moves past the rolling head. In a second phase, the clamping plate with the seal placed on the placement and pressing element is guided to the aperture closure and pressed by the pressing element onto the joining surface of the aperture closure. The embodiment in this solution has a high degree of automation, replacing the manual and complicated manual operation, and completing the placing of the seal in the sealing position of the opening closure.

However, the above method of attaching the seal to the door includes cutting the seal strip into a suitable length on the seal material and then attaching the seal strip, which has the following disadvantages: considering that the sealing section bar has certain elasticity, different lengths can be formed in the stretching process, so that the internal stress of the sealing strip is uneven when the sealing strip is installed on a vehicle door, and the sealing effect is further influenced.

As another example, chinese patent document CN101568442A discloses a method and apparatus for attaching a seal profile. In this solution, the sealing profile is pulled out of the holder and, with the adhesive layer arranged on the sealing profile, is spread along the path provided for the application on the vehicle body or a component of the vehicle body by means of a pressure roller. In order to avoid the problem of uneven internal stresses of the sealing profile after installation, this solution associates the assembly of the sealing profile in terms of time and space with the attachment of the sealing profile to the vehicle body or to a part thereof. However, the application device in this solution is suitable for sealing profiles with heat activated adhesive material, and is difficult to adapt to the current commonly used automotive tape of ST1200 from 3M company.

For another example, chinese patent document CN103707955B discloses a sealing tape bonding apparatus. The apparatus comprises a storage unit for storing the sealing strips and for conveying the sealing strips to a conveying unit. And the conveying unit is used for conveying the sealing strip to the bonding unit. And the bonding unit is used for bonding the sealing strip to the edge of the vehicle door. And a cutting unit for cutting the seal strip after the seal strip is adhered to the door. And the detection unit is used for detecting whether the vehicle door is completely bonded with the sealing strip. And a control unit electrically connected to each of the units and configured to control the conveyance, bonding, and cutting operations of the weatherstrip. And a peeling unit for peeling the sealing strip protective film is arranged between the conveying unit and the bonding unit.

However, the sealing strip bonding equipment is lack of matching between the sealing strip bonding speed and the sealing strip discharging speed, and the sealing strip bonding effect is difficult to ensure; on the other hand, the bonding equipment lacks integration of rolling equipment and a sealing strip protective film recovery device, and is difficult to adapt to the production beat of a full-automatic assembly production line.

To sum up, in the process of pasting the door sealing strip, how to design a pasting type sealing strip installing system for guarantee the fastness of pasting the sealing strip and the door, improve the installation efficiency, just become the technical problem that the technical staff in the field needs to solve urgently.

Whether the discharging rotating wheel 58 has power output or not is adjusted by controlling the on-off of the discharging clutch 52, and then the output distance value of the sealing section bar is adjusted according to the displacement value of the connecting plate unit 1 driven by the vehicle door as a reference motion device to move relative to the vehicle door.

The outlet end 56 is also provided with an interface detection sensor 55. The interface detection sensor 55 is used for detecting the interface of the sealing strip after the door sealing strip pasting installation system rolls for a circle, namely the end of the sealing strip when pasting the starting point. The signal of the interface information detected by the interface detection sensor 55 is transmitted to the cutting device, and the piston end of the cutting cylinder 53 acts to drive the cutting knife 54 to cut the sealing tape 7.

As shown in fig. 9 in conjunction with fig. 10, the guard band recovering unit 6 includes a recovering power unit and a recovering tip 62 that holds the guard band. The trailing end of the recovery head 62 is provided with a guard band outlet 68. The recovery power means pulls the guard band 8 to the guard band outlet 68.

The recovery power unit includes a recovery motor 65 and a recovery clutch 61. The recovery head 62 is provided with a recovery turning wheel 66 and a recovery auxiliary wheel 67. The recovery turning wheel 66 and the recovery auxiliary wheel 67 form a grip on the guard belt. The output shaft of the recovery motor 65 is coupled to the input of the recovery clutch 61. The output end of the recovery clutch 61 is coupled to the rotating shaft of the recovery pulley 66. One side of the recovery auxiliary wheel 67 is provided with a guard belt tensioning mechanism 63 that improves the clamping force.

A guard band detection sensor 64 is also provided at the inlet of the recovery head 62. The guard band detection sensor 64 is used to detect whether the guard band 8 is broken, ensuring that the guard band 8 is pulled and completely recovered.
