[0021] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows: The initial state is: Cylinder one 204 is not started, the rotating block 203 is not rotating, the fixed plate 205 is in a vertical state, the cylinder two 409 is not contracted, the lifting plate 206 is located at the top end of the sliding groove three 410, the electric telescopic rod one 302, the electric telescopic rod two 303, the electric telescopic rod three 316, the motor one 309, the electromagnet 311 and the motor two 312 are not started, the spring one 315 is not squeezed, the spring two 404 is in a squeezed state, the double connecting rod 402 conflicts with the adjacent push plate 403, the spring three 407 is in a squeezed state, the slider 406 is located in the middle of the sliding groove two 405, the spring four 412 is in a squeezed state, the fixed seat 207 is located in the middle of the sliding rod 209, and the spring five 414 is in a squeezed state.

[0022] The working status is: Secure the doors: When the car door on the external placement rack needs to be installed on the car body, the staff holds the handle 208 and controls the power-assisted mechanical arm 1 through the controller on the handle 208, so that the power-assisted mechanical arm 1 moves the placement seat 215 to the bottom of the car door, and then drives the placement seat 215 to move up, so that the bottom of the car door is stuck in the triangular groove of the placement seat 215, and then the staff releases the limit of the car door on the external car door placement rack, so that the weight of the car door falls on the placement seat 215, and then the staff pushes the car door to tilt it toward the fixed column 201. At this time, the window glass of the car door contacts the vacuum suction cup 211, and the staff can use the controller to make the vacuum suction cup 211 suck the window glass, so that the car door is fixed on this device.

[0023] Door cushioning: When the staff operates the power-assisting mechanical arm 1 to make the placement seat 215 rise until the placement seat 215 contacts the vehicle door, the reaction force generated by the contact between the placement seat 215 and the bottom of the vehicle door will press down the shock-absorbing plate 401, causing the shock-absorbing plate 401 to move downward and squeeze the double connecting rod 402, so that the double connecting rod 402 pushes the push plate 403 under the squeezing action, and then the push plate 403 squeezes the spring two 404, and the reaction force is relieved by the spring two 404. When the vehicle door tilts on the placement seat 215 toward the power-assisting mechanical arm 1, the vehicle door contacts and squeezes the vacuum suction cup 211, so that the baffle 413 squeezes the spring five 414 for buffering, thereby preventing the vacuum suction cup 211 from being crushed when the vehicle door is tilted, thereby achieving the buffering effect, which can effectively avoid damage caused by the rigid contact between the device and the bottom of the vehicle door and reduce wear caused by collision.

[0024] Insert the connector: After the vehicle door is fixed on the top of the placement seat 215, the staff puts the bolt into the screwdriver bit 306 and starts the electromagnet 311. The electromagnet 311 produces an adsorption effect on the moving iron core 314, so that the moving iron core 314 drives the screwdriver bit 306 to slide into the movable groove 313 and squeezes the spring 1 315, so that the bolt is adsorbed on the screwdriver bit 306 under the action of magnetic force. Then the staff continues to control the power-assisting mechanical arm 1 through the controller, so that the power-assisting mechanical arm 1 drives the vehicle door to move toward the vehicle body, so that the hinge connector of the vehicle door is close to the hinge connection of the vehicle door, and then the staff uses the power-assisting mechanical arm 1 to insert the hinge connector of the vehicle door into the hinge connection of the vehicle door.

[0025] Hinge Cushioning: During the process of aligning the door hinge connector with the door hinge connection and gradually inserting it, if the door hinge connector is not fully aligned with the door hinge connection, when the staff further controls the power-assisted mechanical arm 1 to drive the door closer to the vehicle body, the door hinge connector that has not been fully aligned will collide with the door hinge connection, and the impact will be transmitted to the door through the door hinge connector, causing the connection between the door and the placement seat 215 and the vacuum suction cup 211 to be impacted. At this time, the door will drive the vacuum suction cup 211 and the placement seat 215 to move away from the vehicle body, so that the pipe sleeve 210 squeezes the spring four 412 for buffering. At the same time, the placement seat 215 will slide on the surface of the shock absorbing plate 401, so that the slider 406 squeezes the spring three 407, thereby further buffering and absorbing energy to avoid damage to the door hinge connection and other connections due to rigid contact.

[0026] Insert the bolt: After the door hinge connector is inserted into the door hinge connection, the industrial camera 310 can be started. After the industrial camera 310 detects the bolt hole position, the electric telescopic rod three 316 is started to drive the rotating frame one 301 to rise and fall, thereby driving the screwdriver bit 306 and the bolt to rise and fall through the electric telescopic rod one 302, the electric telescopic rod two 303 and the rotating frame two 304, so that the bolt moves to the same height as the bolt hole position, and then the controller starts the motor two 312, the motor two 312 drives the electric telescopic rod one 302 to rotate, so that the electric telescopic rod one 302 drives the rotating frame two 304 to swing. Since the electric telescopic rod one is initially The length of the electric telescopic rod 302 is consistent with that of the electric telescopic rod 2 303, so that the rotating frame 1 301, the electric telescopic rod 1 302, the electric telescopic rod 2 303 and the rotating frame 2 304 together form a parallelogram. When the electric telescopic rod 1 302 drives the rotating frame 2 304 to rotate, the electric telescopic rod 2 303 rotates synchronously, so that when the electric telescopic rod 1 302 rotates, the mounting seat 305 gradually approaches the door hinge connection, and the electric telescopic rod 1 302 and the electric telescopic rod 2 303 can be synchronously extended and retracted, so as to adjust the position of the mounting seat 305. At the same time, according to the different angles of the bolt holes, The electric telescopic rod 1 302 or the electric telescopic rod 2 303 is controlled to be extended or retracted separately. When the electric telescopic rod 1 302 is extended or retracted separately, the rotating frame 2 304, the electric telescopic rod 2 303 and the mounting seat 305 are driven to rotate accordingly, so that the direction of the bolt can be adjusted. When the electric telescopic rod 2 303 is extended or retracted separately, the rotating frame 2 304, the electric telescopic rod 1 302 and the mounting seat 305 are driven to rotate accordingly, so that the bolt in the screwdriver bit 306 can be aligned with the mounting hole position, so as to achieve the effect of adapting to the installation requirements of different models of car doors. It should be noted that the industrial camera 310 is used to detect the bolt hole position and It is a prior art to drive the bolt on the mounting seat 305 to align with the bolt hole by means of a controller or other devices, and its principle is not elaborated here. When the bolt is aligned with the mounting hole, the electromagnet 311 is powered off, the spring 315 is reset and stretched, and pushes the moving iron core 314 and the screwdriver bit 306 to slide in the direction close to the mounting hole, thereby inserting the bolt in the screwdriver bit 306 into the mounting hole. Subsequently, the motor 309 is started, driving the driving gear 308 to rotate, and the driving gear 308 drives the screwdriver bit 306 to rotate through the driven gear 307, so that the bolt can be initially screwed into the mounting hole, saving time and effort, and helping to improve the efficiency of door assembly.

[0027] Flexible adjustment: According to the different heights of car doors of different models, cylinder 2 409 can be started before the vacuum suction cup 211 adsorbs the car door, so that cylinder 2 409 contracts, and cylinder 2 409 drives the lifting plate 206 to descend. The lifting plate 206 slides downward inside the sliding groove 3 410 under the limit of the limit block 411, thereby driving the fixing seat 207 to descend, and then driving the sliding rod 209, the pipe sleeve 210 and the vacuum suction cup 211 to descend. Therefore, when installing a small car door, the vacuum suction cup 211 can be lowered to a position aligned with the car window glass, which is more applicable.

[0028] The above descriptions are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
