Description
Technical Field
The invention relates to the technical field of vehicle door sealing strip installation, in particular to an automatic rolling device for a vehicle door sealing strip and a rolling method using the automatic rolling device for the vehicle door sealing strip.
Background
On a vehicle door sealing strip assembly production line, the existing rolling installation equipment for the vehicle door sealing strips which are applied more is in a semi-automatic rolling mode. In the process of using the semi-automatic rolling installation equipment, sealing strips need to be installed on the equipment manually, then the vehicle door is moved to the equipment, and after the adhesion is completed, the vehicle door also needs to be moved down manually. And after the sealing strips of the single vehicle door are assembled, the rest vehicle doors of the same vehicle are sequentially installed. Therefore, the labor intensity of personnel is high, more manpower is needed, a large amount of assembly time is consumed, and the production efficiency of the vehicle assembly production line is influenced. Therefore, a corresponding automatic installation scheme needs to be designed and developed for the installation process of the automobile door sealing strip.
Through search, chinese patent document CN113460744A discloses an automatic bonding device for a door weather strip. The device comprises a base and a support column arranged at the upper end of the base. The upper end of the supporting column is provided with a mounting substrate. The mounting substrate is provided with a winding roller for winding the weatherstrip. The winding roller is connected with a feeding motor for driving the winding roller to rotate. And a conveying assembly for conveying the sealing strips is arranged on the surface of the mounting substrate on the right side of the winding roller. The right end of the mounting substrate is provided with a pasting guide component for pasting the sealing strip on the edge of the vehicle door and a cutting component for cutting the sealing strip. The device not only can carry out the centre gripping with carrying out the transport to different model sealing strips, can also adsorb fixedly to the sealing strip when pasting to the sealing strip guide, has avoided the problem that the sealing strip drops to appear.
Although, above-mentioned automatic bonding device of door sealing strip compares in semi-automatic roll extrusion installation setting, has improved the installation effectiveness of door sealing strip to a certain extent, however, this automatic bonding device of door sealing strip lacks the detection feedback device to the sealing strip at transportation process, is difficult to guarantee the installation effect of sealing strip, and then influences the leakproofness of door in the use. The flexible sealing strip for the vehicle door is easy to stretch or compress due to the change of the conveying speed in the conveying process, so that the sealing strip has different internal stresses at different pasting sections, and the overall sealing performance of the vehicle door is greatly influenced.
For another example, chinese patent document CN103707955A 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.
Although the sealing strip bonding equipment ensures the stability of the conveying speed of the sealing strip in the bonding process by arranging the storage unit and improving the speed control precision of the conveying unit for conveying the sealing strip, the conveying speed of the sealing strip is still difficult to ensure to be completely matched with the actual bonding rolling speed, and the bonding quality of the sealing strip is further influenced.
For another example, chinese patent document CN112896375A discloses a door weather strip attaching system and attaching method. The sticking and mounting system comprises a connecting plate unit, a feeding unit, a buffering unit, a material conveying unit, a discharging unit and a protective belt recycling unit. The sealing strips enter the pasting installation system from the feeding unit, pass through the buffer unit and form buffer stock in the buffer unit. The buffer storage material is fed outwards by the buffer unit on one hand and pulled upwards by the material conveying unit on the other hand, so that the sealing strip is conveyed to the discharging unit. At the discharging unit, the protective belt of the sealing strip is peeled off, the pasting surface of the sealing strip is attached to the car door, and the protective belt is collected by the protective belt recovery unit through guiding.
Although the vehicle door sealing strip pasting and installing system further avoids stretching or compressing the sealing strip in the installation process by ensuring that the pasting speed of the vehicle door sealing strip is the same as the discharging speed of the rolling head, the design only carries out linear speed matching on the detailed subsection of a single vehicle door, the vehicle door sealing strip pasting and installing system at least needs to be divided into more than 100 sections, and the workload of a debugging stage is huge for a control system and debugging personnel. After debugging is completed, because signal transmission exists between the motor control system and the robot control system, reaction time exists. Even if the reaction time is within 20ms, the rolling and pasting quality is affected. In addition, when the door panel beating has slight size fluctuation or the sealing strip density has fluctuation, the door sealing strip interface clearance is difficult to control, and then leads to pasting the quality unstability.
To sum up, how to design an automatic rolling installation device in the process of pasting the door sealing strip for optimizing the sealing strip conveying speed and the control scheme matched with the pasting speed, improving the sealing strip pasting quality and improving the installation efficiency of the sealing strip becomes a technical problem to be solved urgently by technical personnel in the field.
