[0051] Reference Figure 5 and Fig. 9 Then, the clamping member 5 falls downward onto the support plate 626 under the action of gravity, so that the support plate 626 lifts the clamping member 5, so that the connecting column 51 moves downward relative to the connecting sleeve 33, thereby causing the relative position of the positioning groove 331 on the connecting sleeve 33 and the connecting column 51 to be offset, and when the clamping member 5 falls on the support plate 626, the push rod 611 moves upward for a distance under the action of the locking spring 613, so that the push rod 611 keeps contacting the unlocking plate 622, so that the push rod 611 drives the locking rod 612 to move upward for a distance, so that the end of the locking rod 612 away from the push rod 611 moves to the locking hole 511, and at this time, the locking rod 612 is staggered with the positioning groove 331. Then, as the main robotic arm 31 continues to drive the clamping member 5 to move in the direction of the replacement box 4, the clamping member 5 is driven to move to the replacement notch 625. At this time, the unlocking ring 621 is separated from the unlocking block 624, so that the unlocking ring 621 moves upward and resets under the action of the unlocking spring 623, so that the unlocking ring 621 drives the unlocking plate 622 to move upward and reset, so that the unlocking plate 622 is separated from the push rod 611, and the push rod 611 moves upward and resets under the action of the locking spring 613, thereby driving the locking rod 612 to move upward and reset, so that one end of the locking rod 612 slides along the guide groove 6171 of the guide block 617 to the locking hole 511 and extends out of the locking hole 511 again, and then the main robotic arm 31 moves upward, while the clamping member 5 is maintained on the support plate 626 under the action of gravity, so that the connecting sleeve 33 is separated from the connecting column 51, thereby separating the main robotic arm 31 from the clamping member 5.

[0052] Reference Figure 5 and Fig. 9, and then the main robot arm 31 drives the connecting sleeve 33 to move to the replacement notch 625 of another replacement station, and then the main robot arm 31 drives the connecting sleeve 33 to move downward until the connecting sleeve 33 is placed on the connecting column 51, and then as the connecting sleeve 33 moves downward, the end of the connecting sleeve 33 hits the top wall of the locking rod 612 at one end outside the connecting column 51, thereby squeezing the locking rod 612 into the connecting column 51, so that the locking rod 612 pushes the top rod 611 to move downward and compresses the locking spring 613, so that the end of the locking rod 612 hits the inner wall of the connecting sleeve 33, and as the connecting sleeve 33 moves downward, the end of the locking rod 612 slides along the inner wall of the connecting sleeve 33 toward the direction of the positioning groove 331. When the end of the locking rod 612 slides to the positioning groove 331, the top rod 611 moves upward under the action of the locking spring 613, thereby driving the locking rod 612 to move upward, so that the end of the locking rod 612 away from the top rod 611 extends out of the connecting column 51 and is inserted into the positioning groove 331, thereby positioning the connecting column 51 on the connecting sleeve 33, and supporting the locking rod 612 through the support rod 616. Then, the main robot arm 31 drives the connecting sleeve 33 to continue to press down the clamp 5, thereby pressing down the support plate 626 through the clamp 5, so that the support plate 626 moves downward and compresses the return spring 627, and then the main robot arm 31 drives the clamp 5 to move horizontally away from the replacement box 4, so that the connecting column 51 on the clamp 5 moves from the replacement notch 625 to below the unlocking block 624. At this time, the unlocking ring 621 is located below the unlocking block 624, so that the connecting column 51 and the connecting sleeve 33 remain positioned and connected until the main robot arm 31 drives the clamp 5 to separate from the support plate 626 and the unlocking block 624, thereby completing the replacement of the clamp 5.

[0053] Reference Fig.10 A male connector 7 is also fixedly installed in the connecting column 51, one end of the male connector 7 extends out of the end of the connecting column 51, and the other end of the male connector 7 is connected to the clamping member 5. A female connector 8 is fixedly installed in the connecting sleeve 33, and the female connector 8 is used to be plugged into the male connector 7, and the female connector 8 is connected to the main robotic arm 31. The main robotic arm 31 is connected to the female connector 8 through the male connector 7, so as to supply power to the clamping member 5 and transmit electrical signals. The specific principles of power supply and transmission of electrical signals are the existing technology in this field and will not be elaborated here.

[0054] The working principle of the embodiment of the present application is: the parts of the automobile cabin assembly product are transported to the output end of the circulation cabin 2 in sequence according to the assembly order through the circulation cabin 2, and then the main robotic arm 31 drives the clamping member 5 to move to the output end of the circulation cabin 2, and the parts are grasped by the clamping member 5, and the parts are transported to the base plate 1 in sequence, and then the parts are assembled and connected by the auxiliary robotic arm 32 to form the automobile cabin assembly product, and after the assembly is completed, the automobile cabin assembly product is transported to the next process.

[0055] When the clamping part 5 needs to be replaced due to the size requirement of the part, the main robot arm 31 drives the original clamping part 5 to move to the replacement station of the replacement box 4, so that the original clamping part 5 is placed on the replacement station in a vacant state under the action of the unlocking component 62, so that the clamping part 5 is separated from the main robot arm 31, and then the main robot arm 31 drives the connecting sleeve 33 to move to another replacement station, and the connecting sleeve 33 is placed on the new clamping part 5, and the connecting column 51 is connected to the connecting sleeve 33 by the locking component 61. Finally, the main robot arm 31 drives the new clamping part 5 to move away from the replacement box 4, thereby completing the replacement of the clamping part 5.

[0056] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
