[0056] The positioning pin mechanism 1 extends into the positioning hole 101 and is locked with the positioning hole 101 after being deformed;

[0057] The clamping mechanism 2 extends out and clamps the B-pillar 104 of the side panel 10;

[0058] The support mechanism 3 is respectively in contact with the first positioning portion 102 and the second positioning portion 103, and grooves of different widths of the support mechanism 3 support the front window frame and the rear window frame of the side panel 10, so that the support mechanism 3 and the clamping mechanism 2 form a three-point support for the side panel 10;

[0059] The gripping device transports the side panel 10 to abut against the vehicle body, the travel detection component confirms that the side panel 10 is in place, and the buckle device securely connects the side panel 10 to the vehicle body.

[0060] In the above scheme, the positioning method of the flexible positioning device provided by the present application, first, the gripping device is separated from the punching buckle device, which reduces the influence of the rigid structure of the punching buckle device on the flexibility of the gripping process of the gripping device, and enhances the flexible positioning effect of the flexible positioning device on the side panel 10; secondly, the support mechanism 3, the clamping mechanism 2 and the window frame and the B-pillar 104 cooperate to form a three-point support for the side panel 10, and then cooperate with the information grabbing process of the visual detection part to improve the stability and accuracy of the gripping device in gripping the side panel 10; and, the deformation structure of the positioning pin mechanism 1 can be connected to the positioning holes 101 of different depths and diameters, the opening and closing of the clamping mechanism 2 can be connected to the B-pillars 104 of different widths and positions, and the grooves of different widths of the support mechanism 3 can be connected to window frames of different widths, so that the gripping device can be compatible with the pre-installation of side panels 10 of different vehicle models, thereby reducing the pre-installation cost of the side panel 10.

[0061] In some embodiments, the side wall 10 of the automobile is installed on the side of the vehicle body, covers the area of ​​the side of the vehicle body from the bottom of the door to the roof, and is located between the front and rear wheels. It has the following functions: first, the side wall 10 can enhance the lateral rigidity and strength of the automobile, and improve the overall structural stability and safety of the vehicle body; second, the side wall 10 can protect the side of the vehicle body from external impact and scratches, and when the side of the automobile collides, the side wall 10 can absorb and disperse the impact force from the side, protecting the passengers in the vehicle and the internal structure of the vehicle; at the same time, the side wall 10 can provide an installation position for external accessories such as rearview mirrors, door handles, and decorative strips of the automobile.

[0062] A positioning area is preset on the side panel 10 using the positioning method of the present application, and the positioning area includes a positioning hole 101, a first positioning portion 102, a second positioning portion 103 and a third positioning portion 105, wherein the positioning hole 101 is arranged at the part of the side panel 10 close to the front side of the vehicle body, the first positioning portion 102 is arranged on the front window frame of the side panel 10, the second positioning portion 103 is arranged on the rear window frame of the side panel 10, and the third positioning portion 105 is arranged at the rear wheel cover of the side panel 10, and the first positioning portion 102, the second positioning portion 103 and the grabbing point of the B-pillar 104 form a triangular structure.

[0063] In some embodiments, the flexible positioning device is used to grab the side wall 10 and pre-assemble the side wall 10 with the vehicle body. The flexible positioning device of the present application includes a gripper device and a buckle device. The gripper device is used to grab the side wall 10 and process the side wall 10 and transport it to the work station where the vehicle body is located. The buckle device is used to connect the side wall 10 with the vehicle body. The gripper device includes a visual detection part, a positioning pin mechanism 1, a clamping mechanism 2, a support mechanism 3 and a travel detection part.

[0064] The visual detection part is used to capture the spatial position information and vehicle type matching information of the side panel 10 to ensure that the side panel 10 can be accurately installed on the corresponding vehicle body; the positioning pin mechanism 1 is used to dock the positioning hole 101, including a servo module and a hook pin module; the clamping mechanism 2 is used to clamp the B-pillar 104. The supporting mechanism 3 is used to support the window frame of the side panel 10, including the front window frame and the rear window frame; the travel detection part is used to detect whether the side panel 10 is accurately transported to the work station where the vehicle body is located.

[0065] The positioning method of the flexible positioning device of the present application is described below in conjunction with specific embodiments:

[0066] Step S10 , presetting a positioning area on the side panel 10 , the positioning area includes a positioning hole 101 , a first positioning portion 102 and a second positioning portion 103 ; wherein the first positioning portion 102 is arranged on the front window frame of the side panel 10 , and the second positioning portion 103 is arranged on the rear window frame of the side panel 10 .

[0067] In step S10, the depth and diameter of the positioning hole 101 of the side panel 10 of different vehicle models are different, and the widths of the front window frame where the first positioning portion 102 is located and the rear window frame where the second positioning portion 103 is located are also different, which can be selected according to actual needs and are not limited here.

[0068] In step S20 , the gripper device moves to the storage position of the side panel 10 , and the visual detection component grabs the information of the side panel 10 .

[0069] In step S20, the specific process includes:

[0070] Step S201 : The visual detection component captures the spatial position information and vehicle type configuration information of the side panel 10 .

[0071] Specifically, the recognition of spatial position information includes: image acquisition, the visual inspection system uses a high-resolution camera to capture images of the side panel 10 from multiple angles, and these images contain the geometric shape, size and surface features of the side panel 10; feature recognition, through image processing algorithms, the visual inspection system can identify key feature points on the side panel 10, such as edges, contours, holes and marks, etc.; three-dimensional modeling, based on the collected two-dimensional images, the visual inspection system constructs a three-dimensional model of the side panel 10 to obtain its precise position and posture in space.

[0072] The identification of vehicle type matching information is specifically as follows: by comparing the characteristics of the side panel 10 with the information in the vehicle type database, the system can determine the specific vehicle type to which the side panel 10 belongs.

[0073] It can be understood that by grasping the spatial position information and vehicle model matching information of the side panel 10 through the visual detection part, it is possible to realize automated and intelligent assembly of the side panel 10, facilitate the gripper device to match the side panel 10 of different vehicle models, improve production efficiency, and ensure assembly quality and consistency.

[0074] Step S202: The gripper device adjusts the docking position with the side panel 10 along the first direction, the second direction and the third direction according to the spatial position information. It is understandable that the spatial positions of the side panels 10 of different vehicle models may differ to a certain extent in the first direction, the second direction and the third direction. The gripper device can be adjusted in advance according to the position of the side panel 10 to speed up the gripping process.

[0075] Step S30 , the positioning pin mechanism 1 extends into the positioning hole 101 , and is locked with the positioning hole 101 after being deformed.

[0076] In step S30, the specific process includes:

[0077] Step S301: the positioning pin mechanism 1 adjusts the docking length between the movable clamping jaw and the positioning hole 101 according to the depth of the positioning hole 101, so that different first serrations 11 are docked with the positioning hole 101.

[0078] Specifically, the positioning pin mechanism 1 includes a servo module and a latch module, the latch module includes a latch cylinder and a movable clamp, and the movable clamp has a plurality of first sawtooth grooves 11 distributed along the circumferential direction. The servo module is used to adjust the movement of the latch module along the second direction and the third direction, ensure that the latch module can be accurately docked with the positioning hole 101 of the side panel 10 in the second direction and the third direction, and adjust the length of the latch module extending into the positioning hole 101 to match the positioning holes 101 of different depths.

[0079] Step S302: the positioning pin mechanism 1 adjusts the radial deformation of the movable clamping jaw according to the diameter of the positioning hole 101.

[0080] Specifically, the detent cylinder of the detent module can drive the movable jaw to move along the first direction, and control the movable jaw to expand or contract along its radial direction, thereby adjusting its expanded diameter to match the positioning holes 101 of different diameters.

[0081] In step S40 , the clamping mechanism 2 extends out and clamps the B-pillar 104 of the side panel 10 .

[0082] In step S40, the clamping mechanism 2 includes a first clamping arm 21 and a second clamping arm 22, and the first clamping arm 21 and the second clamping arm 22 can move relative to each other. It can be understood that by changing the relative movement distance between the first clamping arm 21 and the second clamping arm 22, B-pillars 104 of different widths can be matched.

[0083] In step S50 , the support mechanism 3 abuts against the first positioning portion 102 and the second positioning portion 103 respectively, and grooves of different widths of the support mechanism 3 support the front window frame and the rear window frame of the side panel 10 , so that the support mechanism 3 and the clamping mechanism 2 form a three-point support for the side panel 10 .

[0084] The support mechanism 3 includes a first support component 31 and a second support component 32. The first support component 31 is provided with a plurality of second sawtooth grooves of different widths, and the second support component 32 is provided with a plurality of third sawtooth grooves of different widths. The widths of the second sawtooth grooves and the third sawtooth grooves can be selected according to actual needs and are not limited here. Step S50 specifically includes:

[0085] Step S501, the first supporting assembly 31 adopts different second sawtooth grooves to support and abut against the first positioning portion 102 to support the front window frame according to the width of the flange structure of the front window frame;

[0086] In step S502 , the second supporting assembly 32 uses different third serrations to abut against the second positioning portion 103 and support the rear window frame according to the width of the flange structure of the front window frame.

[0087] It can be understood that the second serrated grooves and the third serrated grooves of different widths can be used to connect the front window frames and the rear window frames of different widths, and form a three-point stable support for the side panel 10 with the clamping mechanism 2, while being compatible with the pre-installation of the side panel 10 of different vehicle models.

[0088] In step S60 , the gripping device transports the side panel 10 to abut against the vehicle body, the travel detection component confirms that the side panel 10 is in place, and the buckle device securely connects the side panel 10 to the vehicle body.

[0089] In step S60, it specifically includes:

[0090] Step S601, presetting a plurality of buckle positions on the side panel 10, wherein buckles are provided at the buckle positions;

[0091] Step S602, the buckle punching device moves to the buckle position and applies force to the buckle so that the buckle connects the side panel 10 and the vehicle body. Specifically, the buckle punching device includes a cylinder, and the cylinder is used to apply force to the buckle;

[0092] Step S603, the buckle punching device exits and moves to the next buckle position until multiple buckles connect the side panel 10 to the vehicle body.

[0093] It can be understood that, through the fixing effect of the clip buckle device, the side panel 10 can be stably connected to the vehicle body, which facilitates the subsequent pre-installation process of other parts.

[0094] After step S60, the method further includes step S70, a rear wheel housing auxiliary positioning process, which specifically includes:

[0095] Step S701, presetting a third positioning portion 105 at the rear wheel housing of the side panel 10;

[0096] Step S702: the buckling device exits the buckling position and moves to the third positioning portion 105 to abut against and support the third positioning portion 105 of the rear wheel cover.

[0097] It is understandable that after the side panel 10 is connected to the vehicle body by means of buckles, there are still other parts that need to be pre-installed. The auxiliary support can improve the accuracy of subsequent pre-installation of other parts and speed up assembly efficiency.

[0098] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
