[0001] This disclosure relates to the field of workpiece processing technology, and in particular to an assembly device for a white body rear cover assembly. Background Technology

[0002] During the manufacturing of the body-in-white, the rear cover assembly needs to be assembled into the corresponding position on the body frame. However, due to the large area and relatively thin thickness of the rear cover assembly, its stability during assembly is not easily guaranteed, and it is prone to deformation. This can affect the accuracy of the fit between the rear cover assembly and the body frame, thus adversely impacting the yield rate and product quality of the body-in-white. Summary of the Invention

[0007] At least one of the positioning blocks is adapted to abut against a first side surface of the rear cover assembly along the first direction, wherein the positioning hole is located on the first side surface;

[0008] The first fixing mechanism is adapted to fix the rear outer panel of the rear cover assembly;

[0011] The second fixing mechanism corresponds one-to-one with the positioning block. The second fixing mechanism includes a clamping block and a first driving member. The clamping block can be located on one side of the corresponding positioning block along the first direction. The first driving member is used to drive the clamping block to switch between an avoidance position and a clamping position.

[0012] In the avoidance position, the clamping block can prevent the corresponding positioning block from approaching the rear cover assembly along the first direction; in the clamping position, the clamping block can abut against the second side of the lower edge or the second side of the upper edge to clamp the corresponding upper edge or the lower edge with the corresponding positioning block.

[0013] In some possible implementations, the positioning mechanism includes at least three positioning blocks, at least two of which abut against at least one of the lower edge and the upper edge, and are spaced apart along the corresponding lower edge or the upper edge.

[0014] In some possible implementations, the first fixing mechanism includes a plurality of suction cups adapted to adhere to a first side of the rear outer panel and spaced apart on a corresponding side surface of the rear outer panel.

[0015] In some possible implementations, the body-in-white rear cover assembly assembly further includes a limiting mechanism for limiting the upper edge of the rear cover assembly along the first direction.

[0016] In some possible implementations, the body-in-white rear cover assembly assembly includes at least two limiting mechanisms, which are spaced apart along the upper edge and each includes a limiting block.

[0017] At least two of the limiting blocks can abut against the inner surface of the upper edge, respectively;

[0018] Preferably, the limiting block corresponds one-to-one with the mounting bolt on the upper edge;

[0019] The limiting block includes two sub-limiting blocks, both of which abut against the inner surface of the upper edge, and the two sub-limiting blocks are respectively located on opposite sides of the corresponding assembly bolts.

[0020] In some possible implementations, the limiting mechanism further includes a second driving member, which is used to drive the corresponding limiting block to switch between a limiting position and an avoidance position.

[0021] In the avoidance position, interference between the limiting block and the upper edge can be avoided when the limiting block moves along the first direction; in the limiting position, the limiting block can abut against the inner surface of the upper edge.

[0022] In some possible implementations, the body-in-white rear cover assembly assembly also includes multiple vision cameras and controllers;

[0023] Multiple vision cameras are adapted to be distributed around the rear cover assembly and to take pictures of the outline of the rear cover assembly and the outline of the rear door opening of the vehicle frame.

[0024] The controller is connected to the vision camera and is used to receive the image signals acquired by the vision camera and analyze the positional deviation between the outline of the rear cover assembly and the outline of the rear door opening of the vehicle body frame.

[0025] In some possible implementations, the body-in-white rear cover assembly assembly device further includes a frame adapted to be connected to an assembly robot and connected to the positioning pin, the positioning block, the first fixing mechanism, the second fixing mechanism and the vision camera respectively;

[0026] The assembly robot is used to drive the frame to move;

[0027] The controller is signal-connected to the assembly robot and is used to send action commands to the assembly robot based on the positional deviation between the outline of the rear cover assembly and the outline of the rear door opening of the vehicle body frame.

[0028] In some possible implementations, the frame includes a connected lower frame and an upper frame;

[0029] The lower frame is connected to the positioning pin, the positioning block, the first fixing mechanism, and the second fixing mechanism, respectively.

[0030] The upper frame is connected to the vision camera;

[0031] Preferably, a first connector is provided in the middle of the lower frame;

[0032] A second connector is provided in the middle of the upper frame, which is adapted to be connected to the first connector and the assembly robot respectively.

[0033] In the solution disclosed herein, two locating pins can position the rear cover assembly in a plane perpendicular to the first direction, while preventing rotation of the rear cover assembly in the same plane. The locating block can position the rear cover assembly along the first direction. This allows for accurate positioning of the rear cover assembly in three-dimensional space, thus improving the accuracy of rear cover assembly assembly, reducing assembly errors, and facilitating subsequent fixing of the rear cover assembly, thereby improving the stability of the rear cover assembly fixation.

[0034] The first fixing mechanism can fix the rear outer panel of the rear cover assembly, while at least two second fixing mechanisms can fix the lower and upper edges of the window frame sheet metal. This enables the fixing of each part of the rear cover assembly, which not only provides high stability but also helps to prevent deformation of the rear cover assembly, improves the accuracy of the rear cover assembly assembly, and reduces assembly errors.

[0051] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0052] refer to Figure 1 and Figure 2 As shown, the rear cover assembly 5 generally includes a rear outer panel 51, a window frame sheet metal 52, and an upper edge 53 connected sequentially from bottom to top. The rear outer panel 51, the window frame sheet metal 52, and the upper edge 53 can be fixedly connected together by welding, bolts, or other means to form the rear cover assembly 5. During the manufacturing of the body-in-white, the rear cover assembly needs to be assembled into the rear door opening area of ​​the body frame.

[0053] The inner circumference of the window frame sheet metal 52 can be used to install the rear windshield, and can have a lower edge 521 and an upper edge 522.

[0054] One of the first side surface 502 and the second side surface 503 of the rear cover assembly 5 can be the outer side surface of the rear cover assembly 5, and the other can be the inner side surface of the rear cover assembly 5. When the rear cover assembly 5 is assembled on the vehicle body frame, the inner side surface is the side surface facing the inside of the vehicle, and the outer side surface is opposite to the inner side surface and is the side surface facing the outside of the vehicle.

[0055] Among them, reference Figure 1 As shown, the first side surface 502 of the rear cover assembly 5 may be provided with at least two positioning holes 501 for auxiliary positioning during the installation of the rear cover assembly 5. For example Figure 1 As shown, the two positioning holes 501 can be symmetrically arranged on opposite sides of the lower edge 521 of the window frame sheet metal 52.

[0056] This embodiment relates to a white body rear cover assembly assembly device, see reference. Figure 3 As shown, the body-in-white rear cover assembly assembly includes a positioning mechanism 1, a first fixing mechanism 2, and at least two second fixing mechanisms 3.

[0057] Continue to refer to Figure 3 As shown, the positioning mechanism 1 includes at least two positioning pins 11 and at least one positioning block 12. Each positioning pin 11 can correspond one-to-one with a positioning hole 501, and the position of each positioning pin 11 can be matched with the corresponding positioning hole 501. For example, in... Figure 1 In the middle, the number of positioning holes 501 on the first side surface 502 can be two, then as Figure 3 As shown, the positioning mechanism 1 may include two positioning pins 11.

[0058] refer to Figure 4 and Figure 5 As shown, at least two locating pins 11 are respectively adapted to be inserted into the locating holes 501 of the rear cover assembly 5 along the first direction X, and the at least two locating pins 11 are spaced apart along the second direction Y, wherein the second direction Y is perpendicular to the first direction X. In this way, rotation of the rear cover assembly 5 in the plane perpendicular to the first direction X can be avoided, and positioning of the rear cover assembly 5 in the plane perpendicular to the first direction X can be achieved.

[0059] refer to Figure 1 and Figure 4 As shown in the XYZ three-dimensional Cartesian coordinate system, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. For example, the second direction Y can be the left-right direction of the vehicle, the first direction X can be the front-back direction of the vehicle, and the third direction Z can be the up-down direction of the vehicle. Thus, when at least two positioning pins 11 are inserted into the positioning holes 501, the rear cover assembly 5 can be positioned in the YZ plane. In this embodiment, the upper edge 53, the lower edge 521, and the upper edge 522 can all extend along the second direction Y.

[0060] refer to Figure 7 and combined Figure 1 and Figure 2 As shown, at least one positioning block 12 is adapted to abut against the first side surface 502 of the rear cover assembly 5 along the first direction X, wherein the positioning hole 501 is located on the first side surface 502.

[0061] During positioning, at least two positioning pins 11 can be inserted into the positioning hole 501 to position the rear cover assembly 5 in a plane perpendicular to the first direction X. In this way, the positioning block 12 can abut against a designated position on the first side surface 502 along the first direction X, thereby enabling the positioning of the rear cover assembly 5 along the first direction X.

[0062] refer to Figure 4 As shown, the first fixing mechanism 2 is adapted to fix the rear outer panel 51 of the rear cover assembly 5.

[0063] refer to Figure 3 and Figure 6 and combined Figure 2 As shown, at least two second fixing mechanisms 3 are adapted to fix the lower edge 521 and the upper edge 522 of the window frame sheet metal 52 of the rear cover assembly 5, respectively.

[0064] As described above, the two locating pins 11 can position the rear cover assembly 5 in a plane perpendicular to the first direction X, while preventing rotation of the rear cover assembly 5 in the same plane. For example, they can restrict the movement and rotation of the rear cover assembly 5 in the YZ plane. The locating block 12 can position the rear cover assembly 5 along the first direction X. This allows for accurate positioning of the rear cover assembly 5 in three-dimensional space, thus improving the accuracy of rear cover assembly assembly assembly, reducing assembly errors, and facilitating subsequent fixing of the rear cover assembly 5, thereby improving the stability of the rear cover assembly 5.

[0065] The first fixing mechanism 2 can fix the rear outer panel 51 of the rear cover assembly 5, while at least two second fixing mechanisms 3 can fix the lower edge 521 and upper edge 522 of the window frame sheet metal 52. This enables the fixing of each part of the rear cover assembly 5 from bottom to top, which not only has high stability, but also helps to avoid deformation of the rear cover assembly, improves the accuracy of the rear cover assembly assembly, and reduces assembly errors.

[0066] In some examples, reference Figure 2 As shown, the positioning mechanism 1 includes at least two positioning blocks 12, and the second fixing mechanism 3 corresponds one-to-one with each positioning block 12. Combined with... Figure 7 and Figure 8 As shown, at least two positioning blocks 12 are adapted to abut against the first side of the lower edge 521 and the first side of the upper edge 522, respectively. That is, at least one positioning block 12 is adapted to abut against the first side of the lower edge 521, and at least one positioning block 12 is adapted to abut against the first side of the upper edge 522.

[0067] Continue to refer to Figure 3 As shown, the second fixing mechanism 3 includes a clamping block 31 and a first driving member 32. The clamping block 31 can be located on one side of the corresponding positioning block 12 along the first direction x. The first driving member 32 is used to drive the clamping block 31 to switch between the avoidance position and the clamping position.

[0068] like Figure 7As shown, in the avoidance position, the clamping block 31 can be prevented from obstructing the corresponding positioning block 12 from approaching the rear cover assembly 5 along the first direction X. For example, in the avoidance position, in the projection plane along the first direction X, the clamping block 31 can be located inside the window frame sheet metal 52, so that when the positioning block 12 approaches the rear cover assembly 5 along the first direction X, the clamping block 31 will not cause obstruction, and the positioning block 12 can abut against the first side of the corresponding upper edge 522 or the first side of the lower edge 521.

[0069] like Figure 8 As shown, in the clamping position, the clamping block 31 can abut against the second side of the lower edge 521 or the second side of the upper edge 522 to clamp the corresponding upper edge 522 or lower edge 521 with the corresponding positioning block 12.

[0070] For example Figure 7 and Figure 8 As shown, the clamping block 31 can switch between a clearance position and a clamping position by rotation. The first driving component 32 may include a motor, which can directly drive the clamping block 31 to rotate, or indirectly drive it via a transmission mechanism. The axis of rotation of the clamping block 31 can be parallel to the direction of extension of the corresponding lower edge 521 or upper edge 522.

[0071] Among them, it is understandable that, Figure 7 and Figure 8 To clearly illustrate the positional relationship between the second fixing mechanism 3 and the positioning block 12, only the positioning block 12 and the second fixing mechanism 3 for clamping the lower edge 521 are shown. The positioning block 12 abuts against the first side of the lower edge 521. In this embodiment, when the clamping block 31 switches from the clearance position to the clamping position, it rotates downward about the corresponding axis, and in the clamping position, it abuts against the second side of the lower edge 521. When the clamping block 31 switches from the clamping position to the clearance position, it rotates upward about the corresponding axis, and in the clearance position, the clamping block 31 can be located above the lower edge 521.

[0072] The positioning block 12 used to clamp the lower edge 521 abuts against the first side of the upper edge 522, and the clamping block 31 rotates upward about the corresponding axis when switching from the clearance position to the clamping position, and can abut against the second side of the upper edge 522 in the clamping position. When switching from the clamping position to the clearance position, the clamping block 31 rotates downward about the corresponding axis, and in the clearance position, the clamping block 31 can be located on the lower side of the upper edge 522.

[0073] The first side of the lower edge 521 and the first side of the upper edge 522 can both be located on the first side surface 502, and the second side of the lower edge 521 and the second side of the upper edge 522 can both be located on the second side surface 503 of the rear cover assembly 5.

[0074] As described above, the positioning block 12 serves both a positioning function and, in conjunction with the clamping block 31, clamps the corresponding upper edge 522 and lower edge 521, effectively restricting the movement of the rear cover assembly 5 along the first direction X, thus fixing the window frame sheet metal 52. Furthermore, since the lower edge 521 and upper edge 522, which are spaced apart along the third direction Z, are both fixed, it also helps to restrict the rotation of the rear cover assembly 5 in the XZ plane.

[0075] In some examples, reference Figure 6 and combined Figure 7 As shown, the positioning mechanism 1 includes at least three positioning blocks 12, at least two of which abut against at least one of the lower edge 521 and the upper edge 522, and are spaced apart along the corresponding lower edge 521 or upper edge 522. For example, at least two positioning blocks 12 can be symmetrically spaced along the second direction Y, and cooperate with the corresponding second fixing mechanism 3 to clamp them at a position symmetrical along the second direction Y on the lower edge 521 or upper edge 522.

[0076] For example, when the positioning mechanism 1 includes three positioning blocks 12, two positioning blocks 12 may abut against the lower edge 521, and one positioning block 12 may abut against the upper edge 522. Alternatively, two positioning blocks 12 may abut against the upper edge 522, and one positioning block 12 may abut against the lower edge 521.

[0077] For example, in this embodiment, such as Figure 6 and combined Figure 8 As shown, when the positioning mechanism 1 includes four positioning blocks 12, two positioning blocks 12 may abut against the lower edge 521, and two positioning blocks 12 may abut against the upper edge 522. However, in other possible embodiments, three positioning blocks 12 may abut against the lower edge 521, and one positioning block 12 may abut against the upper edge 522. Alternatively, one positioning block 12 may abut against the lower edge 521, and three positioning blocks 12 may abut against the upper edge 522.

[0078] In this way, the positioning block 12 cooperates with the corresponding second fixing mechanism 3, which not only improves the stability of clamping the window frame sheet metal 52, but also helps to prevent the rear cover assembly 5 from rotating in the XY plane because multiple positioning blocks 12 are distributed at intervals along the corresponding upper edge 522 or lower edge 521.

[0079] In some examples, reference Figure 4 As shown, the first fixing mechanism 2 includes a plurality of suction cups 21. For example, in Figure 4 In this embodiment, the first fixing mechanism 2 may include four suction cups 21. However, in other embodiments, the first fixing mechanism 2 may include two suction cups 21, three suction cups 21, five suction cups 21, six suction cups 21, etc. In this embodiment, using... Figure 4The first fixing mechanism 2 shown includes four suction cups 21 as an example.

[0080] The plurality of suction cups 21 are adapted to adhere to the first side of the rear outer panel 51 and are spaced apart on the corresponding side surface of the rear outer panel 51. For example, the first side of the rear outer panel 51 may be located on the first side surface 502 of the rear cover assembly 5, the four suction cups 21 may be spaced apart on the corresponding side surface of the rear outer panel 51, and the four suction cups 21 may be symmetrically distributed in pairs along the second direction Y on the rear outer panel 51.

[0081] Therefore, the suction cup 21 can firmly fix the rear outer panel 51 through vacuum adsorption, avoiding displacement and affecting assembly accuracy. At the same time, the first fixing mechanism 2 can play the main role in fixing the rear cover assembly 5, and the second fixing mechanism 3 plays an auxiliary limiting and fixing role. This not only improves the stability of fixing the rear outer panel 51, but also makes it less likely to damage the rear outer panel 51 by using the suction cup 21 as the main fixing method, which is conducive to improving the quality of the body-in-white after the rear cover assembly 5 is assembled.

[0082] In some examples, reference Figure 3 and Figure 6 As shown, the body-in-white rear cover assembly assembly device also includes a limiting mechanism 4, which is used to limit the upper edge 53 of the rear cover assembly 5 along the first direction X.

[0083] refer to Figure 10 As shown, when assembling the rear cover assembly 5, the upper edge 53 needs to be fitted with assembly bolts 531. When installing the assembly bolts 531, the limiting mechanism 4 can prevent the upper edge 53 from moving along the first direction X, thereby improving the stability and efficiency of the assembly.

[0084] In some examples, reference Figure 6 As shown, the body-in-white rear cover assembly assembly includes at least two limiting mechanisms 4, and the at least two limiting mechanisms 4 are spaced apart along the upper edge 53.

[0085] For example, the body-in-white rear cover assembly assembly may include two limiting mechanisms 4, three limiting mechanisms 4, five limiting mechanisms 4, six limiting mechanisms 4, etc. Figure 3 As shown, at least two limiting mechanisms 4 can be symmetrically distributed along the second direction Y.

[0086] refer to Figure 9 and combined Figure 10 As shown, at least two limiting mechanisms 4 each include a limiting block 41. At least two limiting blocks 41 can abut against the inner surface of the upper edge 53 respectively.

[0087] Generally, when installing the mounting bolt 531, it can be installed from the outside of the vehicle body to the inside. The limiting block 41 abuts against the inner surface of the upper edge 53. Without a complicated structure, it can effectively prevent the upper edge 53 from moving along the first direction X.

[0088] In some examples, reference Figure 2 , Figure 3 and combined Figure 6 As shown, the limiting block 41 corresponds one-to-one with the mounting bolt 531 on the upper edge 53.

[0089] Among them, reference Figure 10 As shown, the limiting block 41 includes two sub-limiting blocks 411, both of which abut against the inner surface of the upper edge 53, and the two sub-limiting blocks 411 are located on opposite sides of the corresponding mounting bolts 531.

[0090] In this way, when installing the assembly bolt 531, the force on both sides of the assembly bolt 531 can be evenly distributed.

[0091] In some examples, the outer side of the vehicle body has a large space to accommodate the body-in-white rear cover assembly assembly; therefore, in this embodiment, the first side surface 502 can be the outer surface of the vehicle body, and the second side surface 503 can be the inner surface of the vehicle body. Therefore, referring to... Figure 9 and Figure 10 As shown, the limiting mechanism 4 also includes a second driving member 42, which is used to drive the corresponding limiting block 41 to switch between the limiting position and the avoidance position.

[0092] like Figure 9 As shown, in the avoidance position, interference between the limiting block 41 and the upper edge 53 can be avoided when the limiting block 41 moves along the first direction X. For example, in Figure 10 In the avoidance position, the limit block 41 can be located above the upper edge 53.

[0093] like Figure 10 As shown, in the limiting position, the limiting block 41 can abut against the inner surface of the upper edge 53.

[0094] The second driving component 42 may include a motor, which can directly drive the two sub-limiting blocks 41 to rotate, or indirectly drive them through a transmission mechanism. The axes of rotation of the two sub-limiting blocks 41 can extend along a first direction. When the limiting block 41 switches from the limiting position to the avoidance position, one of the two sub-limiting blocks 41 can rotate clockwise upward around its corresponding axis, and the other can rotate counterclockwise upward around its corresponding axis. When the limiting block 41 switches from the avoidance position to the limiting position, one of the two sub-limiting blocks 41 can rotate counterclockwise downward around its corresponding axis, and the other can rotate clockwise downward around its corresponding axis. This allows the lower ends of both sub-limiting blocks 41 to abut against the inner surface of the upper edge 53.

[0095] In some examples, the body-in-white rear cover assembly also includes multiple vision cameras 6 and a controller 7.

[0096] Multiple vision cameras 6 are adapted to be distributed around the rear cover assembly 5 and to take pictures of the outline of the rear cover assembly 5 and the outline of the rear door opening of the vehicle body frame. For example Figure 4 As shown, the vision camera 6 can be mounted on the periphery of the rear cover assembly 5 via the camera bracket 61.

[0097] refer to Figure 11 As shown, the controller 7 is signal-connected to the vision camera 6, and is used to receive the image signals acquired by the vision camera 6 and analyze the positional deviation between the contour of the rear cover assembly 5 and the contour of the rear door opening of the vehicle body frame. Therefore, it is possible to detect whether the rear cover assembly 5 has been gripped to the accurate position, which helps to improve the assembly accuracy of the rear cover assembly 5.

[0098] In some examples, reference Figure 4 As shown, the body-in-white rear cover assembly assembly device also includes a frame 8, which is adapted to be connected to the assembly robot 9 and to the positioning pin 11, positioning block 12, first fixing mechanism 2, second fixing mechanism 3, and vision camera 6 respectively. Furthermore, when the body-in-white rear cover assembly assembly device also includes a third fixing mechanism 4, the frame 8 can also be connected to the third fixing mechanism 4.

[0099] Assembly robot 9 is used to drive frame 8 to move. For example, assembly robot 9 can be a six-axis robot. In this way, after the positioning pin 11 and positioning block 12 are used to position the rear cover assembly 5, and the rear cover assembly 5 is fixed by the first fixing mechanism 2, the second fixing mechanism 3 and the third fixing mechanism 3, the assembly robot 9 can drive frame 8 to move, thereby moving the rear cover assembly 5 to the rear door opening area of ​​the vehicle frame, so as to facilitate the assembly of the rear cover assembly 5 onto the vehicle frame.

[0100] The controller 7 is connected to the assembly robot 9 by signal and is used to send action commands to the assembly robot 9 based on the positional deviation between the contour of the rear cover assembly 5 and the contour of the rear door opening of the body frame.

[0101] In this way, after receiving the image signal from the vision camera 6 and analyzing the positional deviation between the contour of the rear cover assembly 5 and the contour of the rear door opening of the vehicle frame, the controller 7 can send motion commands to the assembly robot 9, driving the frame 8 and the rear cover assembly 5 fixed on it to move to the optimal matching position. This enables automatic adjustment of the position of the rear cover assembly 5, which helps to improve work efficiency and assembly accuracy of the rear cover assembly 5.

[0102] In some examples, reference Figure 4 As shown, frame 8 includes a connected lower frame 81 and an upper frame 82.

[0103] The lower frame 81 is connected to the positioning pin 11, the positioning block 12, the first fixing mechanism 2, the second fixing mechanism 3 and the third fixing mechanism 3 respectively.

[0104] For example, the positioning mechanism 1 may also include an adjustment component, which may include a first adjustment block 13, a second adjustment block 14, a third adjustment block 15, and a plurality of pads 16.

[0105] like Figure 5 As shown, the second adjusting block 14 can be located on one side of the lower frame 81 along the fourth direction 002. Multiple shims 16 can be sandwiched between the second adjusting block 14 and the lower frame 81. The second adjusting block 14 and the lower frame 81 can be detachably connected by bolts, screws, etc., so that the distance between the second adjusting block 14 and the lower frame 81 can be adjusted by adjusting the number of shims 16 between the second adjusting block 14 and the lower frame 81.

[0106] The third adjusting block 15 can be located on one side of the second adjusting block 14 along the fifth direction 003. Multiple shims 16 can be sandwiched between the third adjusting block 15 and the second adjusting block 14. The third adjusting block 15 and the second adjusting block 14 can be detachably connected by bolts, screws or other means. Thus, the distance between the third adjusting block 15 and the second adjusting block 14 can be adjusted by adjusting the number of shims 16 between the third adjusting block 15 and the second adjusting block 14.

[0107] The first adjusting block 13 can be located on one side of the third adjusting block 15 along the sixth direction 001. Multiple shims 16 can be sandwiched between the third adjusting block 15 and the first adjusting block 13. The third adjusting block 15 and the first adjusting block 13 can be detachably connected by bolts, screws or other means. Thus, the distance between the third adjusting block 15 and the first adjusting block 13 can be adjusted by adjusting the number of shims 16 between the third adjusting block 15 and the first adjusting block 13.

[0108] The positioning pin 11 can be inserted into the first adjusting block 13. The fourth direction 002, the fifth direction 003, and the fifth direction 003 are perpendicular to each other. Therefore, by adjusting the distance between the second adjusting block 14 and the lower frame 81, the distance between the third adjusting block 15 and the second adjusting block 14, and the distance between the third adjusting block 15 and the first adjusting block 13, the position of the positioning pin 11 in three-dimensional space can be adjusted, enabling the positioning pin 11 to position the rear cover assemblies 5 of different sizes with different positions of the positioning holes 501.

[0109] The positioning block 12, the first driving component 32, and the second driving component 42 can be fixedly connected to the lower frame 81 on the side opposite to the upper frame 82 along the first direction by welding, bolts, or other means. The suction cup 21 can be fixedly connected to the lower frame 81 on the side opposite to the upper frame 82 along the first direction by bolts, screws, or other means.

[0110] The sub-limiting block 411 and the clamping block 31 are rotatably connected to the lower frame 81 on the side opposite to the upper frame 82 along the first direction.

[0111] The upper frame 82 is connected to the vision camera 6. For example... Figure 12 As shown, six camera brackets 61 can be fixedly connected to the upper frame 82 by bolts, welding, or other means. The vision camera 6 can be mounted on the camera bracket 61.

[0112] Therefore, by setting the upper frame 82 and the lower frame 81, the distance between the vision camera 6 and the rear cover assembly 5 can be appropriately increased, thereby increasing the shooting range of the vision camera 6. This is beneficial for more clearly capturing the positional deviation between the outline of the rear cover assembly 5 and the outline of the rear door opening of the vehicle frame, thus improving the accuracy of the assembly of the rear cover assembly 5.

[0113] In some examples, reference Figure 12 As shown, a first connector 811 is provided in the middle of the lower frame 81. For example, the first connector 811 can be a high-strength steel plate, or a round plate, a square plate, etc.

[0114] refer to Figure 13 As shown, a second connector 821 is provided in the middle of the upper frame 82. The second connector 821 is adapted to be connected to the first connector 811 and the assembly robot 9 respectively.

[0115] For example, the second connector 821 can be a high-strength steel plate, such as a round or square plate. The second connector 821 can be fixedly connected to the first connector 811 and the assembly robot 9 by means of bolts, welding, etc. The periphery of the second connector 821 can be fixedly connected to the octagonal tube connecting beam by means of welding, bolts, snap-fit, etc., and the camera bracket 61 can be connected to the second connector 821 by the octagonal tube connecting beam.

[0116] Because the second connector 821 and the first connector 811 have high strength, as the main load-bearing components, they enable the frame 8 and the back cover assembly 5 gripped on it to move smoothly under the drive of the assembly robot 9.

[0117] During the assembly of the rear cover assembly 5, the assembly robot 9 can drive the frame 8 to approach the rear cover assembly 5 along the first direction X, causing the positioning pin 11 to be inserted into the corresponding positioning hole 501. This achieves positioning of the rear cover assembly 5 in the YZ plane, limiting its movement in the second direction Y and the third direction Z, and limiting its rotation within the YZ plane. The positioning block 12 then abuts against the first side of the corresponding lower edge 521 or the first side of the corresponding lower edge 522, achieving positioning of the rear cover assembly 5 in the first direction X.

[0118] Subsequently, the suction cup 21 can be used to adhere to the outer surface of the rear outer panel 51, thus fixing the rear outer panel 51. The first driving component 32 can drive the corresponding clamping block 31 to switch from the avoidance position to the clamping position, so that the clamping block 31 can cooperate with the corresponding positioning block 12 to clamp the corresponding lower edge 52 or upper edge 522, thereby fixing the window frame sheet metal 52 and limiting the rotation of the rear cover assembly 5 in the XZ plane. The second driving component 42 can drive the two corresponding sub-limiting blocks 411 to switch from the avoidance position to the limiting position, so that the sub-limiting blocks 411 can abut against the inner surface of the upper edge 53, thereby limiting the upper edge 53 from moving in the first direction X towards the inside of the vehicle body. This completes the fixing of the rear cover assembly 5 on the rear cover assembly assembly assembly device of the body-in-white.

[0119] Next, the assembly robot 9 drives the frame 8 to move, moving the rear cover assembly 5 to the rear door opening area of ​​the vehicle frame. The vision camera 6 then captures images of the outline of the rear cover assembly 5 and the outline of the rear door opening. After receiving the image signal from the vision camera 6, the controller 7 analyzes the positional deviation between the outline of the rear cover assembly 5 and the outline of the rear door opening, and sends action commands to the assembly robot 9. The drive frame 8 then adjusts the position of the rear cover assembly 5 until it reaches the optimal matching position, at which point the rear cover assembly 5 can be installed.

[0120] After the rear cover assembly 5 is installed, the corresponding clamping block 31 can be driven by the first driving component 32 to switch from the clamping position to the avoidance position, and the two corresponding sub-limiting blocks 411 can be driven by the second driving component 42 to switch from the limiting position to the avoidance position. Then, the assembly robot 9 drives the frame 8 to move away from the rear cover assembly 5 along the first direction X, so that the rear cover assembly assembly device of the white body is separated from the rear cover assembly 5.
