In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0033] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects described may be practiced without these specific details.

[0034] In the process of automobile manufacturing, the body-in-white shell plugging and gluing machine is an important equipment in the painting workshop or assembly workshop. With the continuous improvement of the automation and intelligence of the automobile industry, almost all mainstream automobile manufacturers are using this equipment to improve production efficiency and product quality.

[0035] The process objectives of plugging holes and gluing the body-in-white shell are as follows:

[0036] Waterproof and dustproof: The BIW will face various complex environments during use. If the process holes are not effectively blocked, water and dust can easily enter the interior of the vehicle body, which may cause problems such as moisture damage to the electronic equipment inside the vehicle and rust on the metal parts inside the vehicle body. For example, on rainy days, if water enters the interior of the door through an unblocked hole, it will cause the lifting motor, door locks and other components inside the door to malfunction.

[0037] Sound insulation and heat insulation: Appropriate hole blocking can improve the sound insulation and heat insulation performance of the car body to a certain extent. When the external noise tries to enter the car through the process hole, the blocking material can play a buffering and blocking role, reducing the noise transmission. In terms of heat insulation, for example, after the process hole on the partition between the engine compartment and the cockpit is blocked, the heat generated by the engine can be effectively blocked from being transmitted to the cockpit.

[0038] Ensure air quality: Sealing process holes can prevent harmful gases, odors and dust from outside the car from entering the car, providing good air quality for passengers. Especially for vehicles equipped with air purification systems, good body sealing can make the air purification system work better.

[0039] Improve anti-corrosion performance: Blocking the process holes can reduce the chance of contact between the interior of the car body and external corrosive substances. When the car body is in a humid environment or comes into contact with road de-icing agents containing salt, if the process holes are not blocked, these corrosive substances will enter the interior of the car body and accelerate the corrosion process of metal parts. The hole blocking process can effectively extend the service life of the car body.

[0040] Due to the different shapes of the body-in-white shell and the small internal space, the ordinary gluing head is too large and will interfere with the body during work. Therefore, there is a need for a plugging gluing head that can be compatible with the narrow space, but at the same time cannot affect the efficiency of the body hole plugging gluing.

[0041] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0042] like Figure 1-Figure 4 As shown, a vehicle hole blocking device includes:

[0043] Rack 1;

[0044] A first mounting portion 2, wherein the first mounting portion 2 mounts the frame 1 on an external actuator;

[0045] A feeding mechanism 3, the feeding mechanism 3 is installed on the frame 1, and the feeding mechanism 3 is used to place the hole-blocking film;

[0046] The stripping mechanism 4 is installed on the frame 1. The stripping mechanism 4 strips the plugging film provided by the feeding mechanism 3. The stripping mechanism 4 is equipped with a pneumatic motion mechanism. A photoelectric sensor is provided at the front stripping plate, which can quickly and accurately locate the film during feeding.

[0047] A glue sticking mechanism 5, wherein the glue sticking mechanism 5 is installed on the external actuator, and the glue sticking mechanism 5 absorbs the hole plugging film after the glue stripping process, and sticks the hole plugging film to the hole position of the vehicle body;

[0048] The electric control system includes an independent electric control box 7, an electric control signal module 8 and an air control valve island module 9. The electric control signal module 8 and the air control valve island module 9 are connected to the controller of the independent electric control box 7 to receive control instructions and control the glue sticking mechanism 5.

[0049] The hole plugging device is installed on the external actuator through the first mounting part 2. The external actuator can drive the hole plugging device to move in any direction in the space, so as to facilitate the movement of the hole plugging device to the vehicle body. The hole plugging film is provided by the feeding mechanism 3, and the glue stripping mechanism 4 strips the hole plugging film. The glue sticking mechanism 5 absorbs the hole plugging film after the glue stripping process. The external actuator drives the glue sticking mechanism 5 to move and attach the hole plugging film to the hole position of the vehicle body. The vehicle body can be quickly and efficiently sealed with glue, thereby improving production efficiency. At the same time, it is more convenient to plug the holes in the narrow space inside the vehicle body shell with glue.

[0050] It should be noted that the independent electric control box 7 is internally configured with a controller (PLC and circuit board) as the core of the electric control system, and the electric box has an aviation plug on the outside, which can quickly connect the electric control signal module 8 of the plugging and pasting head with the air hole valve island module to achieve logical control. The electric control signal module 8 and the air control valve island module 9 are connected to the controller of the independent electric box to receive control instructions and control the pasting head.

[0051] like Figure 1-Figure 2 As shown, in some embodiments, the gluing mechanism 5 includes an integrated hole-plugging glue head for feeding, and the integrated hole-plugging glue head is used for gluing holes in larger spaces. The integrated hole-plugging glue head is used to glue holes in larger spaces inside the vehicle body. The integrated hole-plugging glue head can quickly and effectively plug the holes and ensure good sealing. It adopts an integrated design and can easily complete the sealing operation without additional tools, thereby simplifying the operating process and improving work efficiency. Compared with traditional sealing parts such as metal plugging covers, the integrated hole-plugging glue head is usually made of lightweight materials, which helps to reduce the overall weight and reduce energy consumption.

[0052] It should be noted that the integrated feeding hole plugging and gluing head has an independent vacuum film taking and plugging mechanism. When the built-in gluing and plugging mechanism is circumvented, it can become a feeding machine.

[0053] like Figure 1-Figure 2 As shown, in some embodiments, the feeding integrated hole plugging rubber head is a vacuum film removal rubber head, and the integrated hole plugging rubber head Caitong vacuum film removal plug can fit tightly to the sealed surface, effectively prevent leakage, and ensure the stability of the vacuum environment. The soft material and fitting design of the vacuum film removal plug can protect the sealed surface from damage during the sealing process, and avoid scratches or wear.

[0054] It should be noted that the vacuum film removal and gluing head is equipped with a vacuum generator to generate vacuum, so that the plug adsorbs the film, and is equipped with a long-stroke linear motion cylinder to stick the film on the hole in the body shell. A pneumatic connecting rod mechanism is configured on the back of the film plugging mechanism. When the pneumatic connecting rod mechanism retracts, the vacuum film removal and gluing head avoids the top of the glue stripping mechanism 4. At this time, the integrated hole-plugging and gluing head for feeding only has the function of feeding.

[0055] like Figure 3-Figure 5 As shown, in some embodiments, the glue sticking mechanism 5 includes a second hole plugging glue sticking head 11, and the second hole plugging glue sticking head 11 includes a second mounting portion 10, N pneumatic cylinders 12 and N vacuum film taking plugs 15, the second mounting portion 10 is mounted on an external actuator, and the N pneumatic cylinders 12 correspond to the N vacuum film taking plugs 15 respectively, and the N pneumatic cylinders 12 drive the corresponding N vacuum film taking plugs to move independently; wherein N is a natural positive integer greater than or equal to 1, and the pneumatic cylinder 12 provides power to control the up and down movement of each plug, and the vacuum film taking plug 15 uses negative pressure to absorb the film and then stick it to the position where the hole needs to be plugged. Since each plug is independently controlled, the position and pressure can be adjusted separately to adapt to holes at different positions or different heights. Independent control can improve flexibility and adapt to different hole positions; the pneumatic cylinder 12 responds quickly and is suitable for high-speed production; vacuum adsorption ensures accurate placement of the film and reduces errors. When a plug has a problem, it does not affect others, thereby improving reliability.

[0056] like Figure 3-Figure 5 As shown, in some embodiments, the glue sticking mechanism 5 further includes N vacuum generators and N guide tubes 14 respectively corresponding to the N vacuum film taking plugs 15, and the vacuum generator is connected to the vacuum film taking plug 15 through the guide tube 14. Each vacuum film taking plug 15 is equipped with an independent vacuum generator, and the plug guide tube 14 can be used as a motion guide and a vacuum pipeline 13, and the end is equipped with N plug suction cups 16, which can absorb and store N films.

[0057] like Figure 3-Figure 5 As shown, in some embodiments, the second mounting portion 10 includes a male or female quick-change fixture disk, and the external actuator is provided with a male or female quick-change fixture disk corresponding to the second mounting portion 10. The second mounting portion 10 is connected to the external actuator by using a fixture quick-change disk. The fixture quick-change disk can quickly switch between different fixtures or tools, so that the robot can quickly switch between different production links, thereby improving the operating efficiency of the overall production line. Traditional manual replacement of fixtures requires a lot of manpower and time, while the quick-change disk adopts electric or pneumatic drive, which reduces manual operation and reduces labor costs.

[0058] It should be noted that the glue head quick-change disk is divided into a male disk and a female disk. It has a locating pin for positioning and adopts air supply locking. It has an air hole plug and a conductive needle and wire plug inside, which can separate or connect the air source and power supply at both ends of the quick-change disk.

[0059] like Figure 1 and Figure 3As shown, in some embodiments, the vehicle hole plugging device also includes a tensioning mechanism 6, which is installed on the frame 1. The tensioning mechanism 6 tensions the film. The tensioning mechanism 6 has an elastic tension stroke of 0-100mm, which can support the tape and always keep the tape in a taut and smooth state.

[0060] like Figure 1-Figure 4 As shown, in some embodiments, the feeding mechanism 3 includes a feeding tray 31 and a motor 32, the film is wound around the feeding tray 31, and the motor 32 is used to drive the feeding tray 31 to rotate. The disc-type coil feeding mechanism 3 can achieve a feeding amount of 3000 to 5000 pieces of plugging film, and is equipped with a quick disassembly handle, which can quickly disassemble the loading and improve the loading efficiency.

[0061] See also Figure 1-Figure 5 Based on the same inventive concept, an embodiment of the present specification provides a hole plugging system, including an actuator, a vehicle body positioning part and a vehicle hole plugging device as described in any one of the above items, wherein the vehicle body positioning part positions the vehicle, and the vehicle hole plugging device is installed on the actuator. By adopting the above-mentioned vehicle hole plugging device, it is possible to quickly plug the holes in the narrow space inside the body shell with glue.

[0062] During implementation, the actuator includes a six-axis industrial robot that can realize multi-position and multi-angle motion positioning. The end of the sixth axis is provided with a mounting flange that can be connected to a quick-change plate for the plugging and gluing head. The six-axis industrial robot is used for precise positioning to realize actions such as material picking by the gluing head and gluing at multiple positions.

[0063] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the method embodiment described later, since it corresponds to the system, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.

[0064] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
