[0049] In the embodiment of the application, referring toFigure 1 As shown, the embodiment of the present application provides a flexible total assembly system, which comprises two subsystems 100 and a total assembly gripper storage 200, the two subsystems 100 are respectively arranged on the two sides of the total assembly station 30 in the production line 10, the subsystem 100 comprises a gripper positioning mounting frame 110, total assembly grippers 120 of multiple vehicle types, a manipulator 130, a gripper storage trolley 140 and at least one gripper storage switching library 150.

[0050] The gripper positioning mounting frame 110 is arranged on one side of the total assembly station 30, and the total assembly gripper 120 is arranged on the gripper positioning mounting frame 110, so that the total assembly gripper 120 can position and clamp the vehicle body 20 on the total assembly station 30.

[0051] The total assembly gripper storage 200 is used to store total assembly grippers 120 of multiple vehicle types, the gripper storage switching library 150 is used to store total assembly grippers 120 of one vehicle type, the manipulator 130 is used to grab total assembly grippers 120 between the gripper positioning mounting frame 110 and the gripper storage switching library 150, and the gripper storage trolley 140 is used to transport total assembly grippers 120 between the total assembly gripper storage 200, the gripper storage switching library 150 and the manipulator 130.

[0052] The two subsystems 100 of the flexible total assembly system of the present application are respectively located on the two sides of the total assembly station 30, that is, one subsystem 100 can position and clamp the side wall, cross beam and other parts on the left side of the vehicle body 20 on the total assembly station 30, and the other subsystem 100 can position and clamp the side wall, cross beam and other parts on the right side of the vehicle body 20 on the total assembly station 30.

[0053] The total assembly gripper storage 200 is used to store total assembly grippers 120 of multiple vehicle types, and the gripper storage switching library 150 is used to store total assembly grippers 120 of one vehicle type.

[0054] The manipulator 130 is used to grab total assembly grippers 120 on the gripper positioning mounting frame 110 to the gripper storage trolley 140 or grab total assembly grippers 120 in the gripper storage switching library 150 to the gripper positioning mounting frame 110, and the gripper storage trolley 140 is used to transport total assembly grippers 120 in the total assembly gripper storage 200 to the gripper storage switching library 150, or transport total assembly grippers 120 on the manipulator 130 to the total assembly gripper storage 200 or the gripper storage switching library 150.

[0055] Specific use, such as when the A car model total assembly gripper 120 installed on the gripper positioning mounting frame 110, the gripper storage switching library 150 stores the total assembly gripper 120 of B car model, when the B car model needs to be welded, at this time the mechanical arm 130 is connected with the total assembly gripper 120 of A car model on the gripper positioning mounting frame 110, the total assembly gripper 120 of A car model is grabbed from the gripper positioning mounting frame 110 to the gripper storage trolley 140, the gripper storage trolley 140 can transfer the total assembly gripper 120 of A car model to any position according to the need, such as in the gripper total storage library 200 or in the gripper storage switching library 150; then the mechanical arm 130 is connected with the total assembly gripper 120 of B car model in the gripper storage switching library 150, the mechanical arm 130 holds the total assembly gripper 120 of B car model and moves to the gripper positioning mounting frame 110, so that the total assembly gripper 120 of B car model is installed on the gripper positioning mounting frame 110, and the welding of B car model can be carried out.

[0056] For example, when the total assembly gripper 120 of A car model installed on the gripper positioning mounting frame 110, the gripper storage switching library 150 stores the total assembly gripper 120 of B car model, and the gripper total storage library 200 stores the total assembly gripper 120 of C car model, when the C car model needs to be welded, at this time the gripper storage trolley 140 transports the total assembly gripper 120 of C car model in the gripper total storage library 200 outside the production line 10 to the gripper storage switching library 150 in the production line 10, and at the same time, the total assembly gripper 120 of B car model in the gripper storage switching library 150 is transported to the gripper total storage library 200 outside the production line 10 by the gripper storage trolley 140.

[0057] Then the mechanical arm 130 is connected with the total assembly gripper 120 of A car model on the gripper positioning mounting frame 110, the total assembly gripper 120 of A car model is grabbed from the gripper positioning mounting frame 110 to the gripper storage trolley 140, and the gripper storage trolley 140 can transfer the total assembly gripper 120 of A car model to the gripper total storage library 200 or the gripper storage switching library 150 according to the need; then the mechanical arm 130 is connected with the total assembly gripper 120 of C car model in the gripper storage switching library 150, the mechanical arm 130 holds the total assembly gripper 120 of C car model and moves to the gripper positioning mounting frame 110, so that the total assembly gripper 120 of C car model is installed on the gripper positioning mounting frame 110, and the welding of C car model can be carried out.

[0058] Because the gripper total storage library 200 is located outside the production line 10, the floor area in the production line 10 can be reduced, and the welding of multiple car models can be met.

[0059] The flexible total assembly system of the present application cancels the existing clamp transportation track arranged in the production line 10 by arranging the subsystem 100 in the production line 10 and arranging the total assembly gripper storage 200 outside the production line 10, then transporting the total assembly gripper 120 in the total assembly gripper storage 200 outside the production line 10 to the gripper storage switching library 150 inside the production line 10 by the gripper storage trolley 140, and then grabbing the total assembly gripper 120 in the gripper storage switching library 150 to the gripper positioning mounting frame 110 by the mechanical hand 130, so that the land area of the production line 10 of the flexible total assembly system is reduced, and the land area of the production line 10 of the flexible total assembly system is further reduced because the total assembly gripper storage 200 is arranged outside the production line 10, solving the technical problem of large land area of the production line of the existing flexible total assembly system.

[0061] Different vehicle models require total assembly grippers 120 that are the same in some parts, such as the front section structure of the vehicle body of the A vehicle model being the same or similar to the front section structure of the vehicle body of the B vehicle model, and the rear section structure of the vehicle body of the A vehicle model being different from the rear section structure of the vehicle body of the B vehicle model. Therefore, the total assembly gripper 120 required for the front section of the vehicle body of the A vehicle model is the same as the total assembly gripper 120 required for the front section of the vehicle body of the B vehicle model, and the total assembly gripper 120 required for the rear section of the vehicle body of the A vehicle model is different from the total assembly gripper 120 required for the rear section of the vehicle body of the B vehicle model. Therefore, when switching the total assembly gripper 120, only the total assembly gripper 120 required for the rear section of the vehicle body needs to be switched, and the total assembly gripper 120 required for the front section of the vehicle body does not need to be switched. Therefore, in this embodiment, the gripper storage switching library 150 is arranged as the total assembly front section gripper storage switching library 151 and the total assembly rear section gripper storage switching library 152, so that when switching the total assembly gripper 120, the number of total assembly gripper 120 switches is reduced, and the switching efficiency of the total assembly gripper 120 is improved.

When it is necessary to switch the vehicle type, the total assembly mechanism 160 drives the total assembly frame 112 to move to the second position, at this time, the total assembly frame 112 is separated from the positioning column 111, and then the total assembly gripper 120 on the total assembly frame 112 can be switched.
