In actual production, the automobile doors clamped on the door hanger are transported to the installation station through the conveying line, and the pasting and rolling of the door sealing strip are completed by the door sealing strip installation robot. The robot drives the connection plate unit to move to the starting point of the sealing strip pasting position of the door, so that the pasting surface of the sealing strip stripped of the protective tape is attached to the door, the clamping force is applied to the sealing strip by the rolling device, and then the robot drives the connection plate unit to walk along the contour of the door for one round, completing the pasting and rolling of the sealing strip.

[0003] Among them, the door hanger usually loads four automobile doors of left, right, front and back into the installation station at a time, the four doors are arranged in pairs on both sides of the door hanger, and the door sealing strip installation robot is arranged on one side of the door hanger for installing the door sealing strip on the near door. In order to ensure the smooth progress of automatic assembly of the door sealing strip and improve the installation effect of the door sealing strip, the door hanger is usually equipped with a clamping device to position and clamp the door, so as to maintain the stability of the door and ensure the accuracy of the installation position during the installation of the door sealing strip.

[0004] However, since the above-mentioned door sealing strip installation robot occupies one side of the door hanger assembly space, the clamping device is usually arranged on the opposite side of the robot, and the door is clamped from the opposite side of the door hanger during clamping. Considering that the robot needs to leave all the space of the door inner plate sealing strip area when installing the sealing strip, in order to position and clamp, and at the same time adapt to the production rhythm of the production line, a fixed long rod needs to be stretched out from the left front door and the right rear door area to the window frame, and the left front side is stretched to the right front side to position the right front door, and the right rear side is stretched to the left rear side to position the left rear door.

[0005] In this way, the clamping device occupies a large amount of assembly space and is located on the opposite side of the door sealing strip installation robot.

DETAILED DESCRIPTION

[0032] The specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0033] At present, in the automobile sealing strip installation station, considering that the vehicle door sealing strip robot installs the sealing strip, all spaces in the sealing strip installation area of the vehicle door need to be given out, the existing clamp equipment is usually arranged at the opposite side of the vehicle door sealing strip installation robot, and the clamp equipment is arranged at the opposite side of the vehicle door lifting appliance.

[0034] For example Figure 1-Figure 7The utility model discloses an equipment for the installation of a door sealing strip, which is used for optimizing the spatial layout of the existing installation station, improving the compatibility between the door hanger and the door, and improving the clamping stability of the door.

[0035] As shown in Figure 1 , As shown in Figure 2 , an equipment for the installation of a door sealing strip is located in an installation station equipped with a door sealing strip installation robot, and cooperates with a door hanger 1 to clamp a door. The door clamping equipment 2 includes a bracket 21 and a clamp unit. The door sealing strip installation robot is not shown in the figure. According to the assembly accuracy and assembly efficiency of the assembly line, a joint robot or a rectangular coordinate robot can be selected to carry an automatic door sealing strip rolling device disclosed in a patent with application number 2022101579092 to complete the installation of the door sealing strip.

[0036] As shown in Figure 1 , the bracket 21 is arranged on the same side as the door sealing strip installation robot along the conveying direction of the door hanger 1. Figure 1 The arrow direction in the figure is the conveying direction of the door hanger 1. As shown in Figure 2 , the bracket 21 is configured to suspend the clamp unit above the door and support the clamp unit to enter between the door and the door hanger 1 from above the door, so that an assembly space 3 is formed between the door and the door hanger 1 for the clamp unit to clamp the window frame of the door.

[0037] As shown in Figure 2 , a pressure head assembly 23 is arranged on the clamp unit. The pressure head assembly 23 is used to apply a pressing force to the door trim at the lower edge of the window frame.

[0038] The door clamping equipment for the installation of a door sealing strip in the utility model embodiment suspends the clamp unit above the door by means of the bracket 21, fully utilizes the assembly space 3 formed between the door and the door hanger 1, avoids interference between the clamping equipment and the door hanger 1 in the conveying direction in the installation station, solves the passability problem of the door hanger 1, and thus optimizes the spatial layout of the installation station. Compared with the opposite clamping mode of the clamping equipment for the door in the prior art, the door clamping equipment for the installation of a door sealing strip and the door sealing strip installation robot are arranged on the same side of the door hanger 1, which releases the assembly space 3 on the opposite side of the door sealing strip installation robot in the installation station, improves the overall space utilization, ensures high compatibility between the door hanger 1, and can adapt to the installation requirements of different models of doors.

[0039] In order to adapt to the assembly line of automobile doors of different specifications and models, the clamp unit is further provided with an adjustment component 22. The adjustment component 22 is configured to drive the pressure head component 23 and adjust the clamping position of the pressure head component 23 in the assembly space 3.

[0040] like Figure 1 Combine Figure 2 As shown, the lower edge of the window frame is arranged along the conveying direction of the door hanger 1, and the clamping plane of the door on the door hanger 1 is used as the reference reference plane 4. In the assembly space 3, the height direction of the door is defined as the first direction, and the thickness direction of the door is defined as the second direction. Figure 2 As shown in the figure, the direction indicated by the arrow pointing upward is the first direction, and the direction indicated by the arrow pointing to the right is the second direction.

[0041] According to some preferred embodiments of the present invention, Figure 2 、 Figure 4 and Figure 5 As shown, the adjustment assembly 22 is provided with a first driving component 223 and a second driving component 224. The first driving component 223 is used to drive the pressure head assembly 23 to perform telescopic movement along the second direction. The second driving component 224 is used to drive the pressure head assembly 23 to perform telescopic movement along the first direction.

[0042] In this way, the adjustment component 22 can flexibly adjust the clamping position of the pressure head component 23 in the assembly space 3 according to the specific conditions of the actual car door, thereby ensuring that the clamping device can accurately adapt to different types of car doors, thereby improving the versatility and compatibility of the equipment.

[0043] like Figure 1 、 Figure 2 As shown, the bracket 21 is in the form of a gantry structure. The fixture unit is arranged on the crossbeam 24 of the gantry structure. An operating channel is formed below the crossbeam 24 of the gantry structure for the door sealing strip installation robot to install the sealing strip on the door. The operating channel provides the door sealing strip installation robot with an unobstructed installation work space. When installing the door sealing strip, there is no need to worry about collision with the clamping equipment, which facilitates more accurate planning of the sealing strip installation operation path. This not only helps to improve the robot's work efficiency and reduce the extra movements and time consumption caused by avoiding the clamping equipment, but also reduces the risk of misoperation due to limited operating space, thereby ensuring the smoothness and stability of the entire door sealing strip installation process.

[0044] According to some preferred embodiments of the present invention, brackets 21 are provided on both sides of the door hanger 1. The clamp units on the brackets 21 on both sides of the door hanger 1 form synchronous clamping for the door located on the same side as the clamp units.

[0045] For example, in an installation station of a car door seal strip, a door seal strip installation robot is usually arranged on both sides of the conveying path of the door hanger 1. The left front door, the right front door, the left rear door and the right rear door of the same car are usually simultaneously loaded on the door hanger 1 into the installation station. The clamp units on the brackets 21 on both sides of the door hanger 1 are respectively matched with the four doors one by one, thereby forming synchronous clamping of the four doors.

[0046] In order to further reduce the use cost of the door clamping device, the number of clamp units can be matched with the number of door seal strip installation robots, and only the door being installed with the seal strip is clamped. For example, in an installation station of a car door seal strip, the clamp units on the brackets 21 on both sides of the door hanger 1 are respectively clamped on the left front door and the right front door, and after the door seal strip installation robot completes the installation of the door seal strip, the left rear door and the right rear door are respectively clamped.

[0047] As shown in Figure 3 , Figure 4 and Figure 5 , the adjusting assembly 22 further comprises a cantilever 221 and a connecting frame 222. The cantilever 221 is installed on the bracket 21 and is arranged above the door. The first driving part 223 is installed on the cantilever 221. The connecting frame 222 is connected to the telescopic end of the first driving part 223. The second driving part 224 is installed on the connecting frame 222. For example, the first driving part 223 and the second driving part 224 are linear cylinders or servo motors.

[0048] As shown in Figure 3 , by adjusting the first driving part 223 and the second driving part 224 in the adjusting assembly 22, the pressure head assembly 23 is adjusted to the required clamping position, so that the pressing block 231 in the pressure head assembly 23 can accurately contact the door trim at the lower edge of the window frame of the door structure, and in combination with the arc of the door structure itself, the pressing force is applied to the door trim at the lower edge of the window frame from above the door structure. Not only the door structure clamped on the door hanger 1 is effectively clamped, ensuring the stability of clamping, but also the pressure head assembly 23 avoids touching the door shell, thereby protecting the paint surface of the door shell.

[0049] As shown in Figure 5As shown, the first guiding mechanism 25 is arranged between the cantilever 221 and the connecting frame 222. The first guiding mechanism 25 is arranged parallel to the extension direction of the first driving component 223. The connecting frame 222 is connected to the cantilever 221 through the first guiding mechanism 25. By arranging the first guiding mechanism 25, the linear motion of the connecting frame 222 relative to the cantilever 221 is ensured to be accurate. When the first driving component 223 is in operation, the connecting frame 222 can move smoothly along the fixed path, ensuring the positioning accuracy of the pressure head assembly 23 and improving the clamping accuracy.

[0050] The arrangement of the first guiding mechanism 25 ensures that the motion trajectory of the connecting frame 222 is stable and does not deviate, effectively preventing unstable clamping caused by motion deviation and further improving the clamping stability and reliability of the vehicle door. At the same time, the first guiding mechanism 25 increases the overall rigidity of the cantilever 221 and the connecting frame 222 system, reduces the vibration and deviation during clamping, ensures the stability of the clamping process, and further improves the installation quality of the sealing strip.

[0051] For example, as shown in Figure 5 The first guiding mechanism 25 includes a first sliding seat 251 and a first guide rail 252. The first guide rail 252 is installed on the cantilever 221. The first guide rail 252 is arranged parallel to the extension direction of the first driving component 223. The connecting frame 222 is connected to the first guide rail 252 through the first sliding seat 251.

[0052] As shown in Figure 4 The second guiding mechanism 26 is arranged on the connecting frame 222. The second guiding mechanism 26 is arranged parallel to the extension direction of the second driving component 224. The pressure head assembly 23 is connected to the connecting frame 222 through the second guiding mechanism. The second guiding mechanism 26 has a similar effect as the first guiding mechanism 25, and the difference between the two is the different guiding directions, which are respectively used to improve the positioning accuracy in the respective guiding directions.

[0053] For example, as shown in Figure 4 The second guiding mechanism 26 includes a second sliding seat 261 and a second guide rail 262. The second guide rail 262 is installed on the connecting frame 222. The second guide rail 262 is arranged parallel to the extension direction of the second driving component 224. The pressure head assembly 23 is connected to the second guide rail 262 through the second sliding seat 261.

[0054] As shown in Figure 4 The pressure head assembly 23 is connected to the extension end of the second driving component 224. The pressure head assembly 23 is provided with a pressing block 231 for contacting the vehicle door inner panel. Among them, the pressing block 231 can be selected as a V-shaped block or a rectangular block according to the actual working condition, so as to better adapt to the shape of the vehicle door inner panel, and further ensure the stability of the clamping of the vehicle door.

[0055] As shown in Figure 5As shown, the pressure head assembly 23 further comprises a base 232 and a rotating mechanism 233 for adjusting the downward angle of the pressure block 231, and the pressure block 231 is connected to the base 232 through the rotating mechanism 233. In this way, the rotating mechanism 233 allows the downward angle of the pressure block 231 to be precisely adjusted, and the pressure block 231 can better adapt to different angles and shapes of the inner panel of the vehicle door when installing the sealing strip. The pressure block 231 equipped with the rotating mechanism 233 can adapt to the curved surface of the inner panel of different models of vehicle doors, improving the applicability and flexibility of the equipment in various vehicle models, making the vehicle door clamping equipment have higher universality in the vehicle door assembly production line of multiple vehicle models, reducing the frequency and cost of replacing equipment.

[0056] In addition, by adjusting the downward angle of the pressure block 231 through the rotating mechanism 233, it can ensure that the clamping force is uniformly distributed on the inner panel of the vehicle door, avoiding deformation or damage of the vehicle door due to uneven force, further improving the stability and safety of clamping.

[0057] As shown in the drawings, Figure 5 In combination Figure 7 As shown, the rotating mechanism 233 comprises a connecting seat 2331, a first rotating shaft 2332 and a second rotating shaft 2333. The first rotating shaft 2332 is arranged parallel to the extension direction of the second driving component 224. The second rotating shaft 2333 is arranged perpendicular to the first rotating shaft 2332. The connecting seat 2331 is connected to the base 232 through the first rotating shaft 2332. The pressure block 231 is connected to the connecting seat 2331 through the second rotating shaft 2333. In this way, the first rotating shaft 2332 and the second rotating shaft 2333 are designed to bring more precise, flexible and efficient angle adjustment capability to the vehicle door clamping equipment, further improving the stability, adaptability and production efficiency of clamping, protecting the outer panel of the vehicle door, and simplifying the operation and maintenance process.

[0058] The utility model is not limited to the specific technical solutions described in the above embodiments, and in addition to the above embodiments, the utility model can also have other implementation manners. For those skilled in the art, any modification, equivalent replacement, improvement, etc. formed within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
