[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example 1: As Figures 1 to 3 The door panel disassembly and assembly device mainly consists of a gripping component 3, a pitch adjustment component 1, and a horizontal distance adjustment component. The gripping component 3 is connected to the pitch adjustment component 1 and the horizontal distance adjustment component. The horizontal distance adjustment component includes several hinged rotating arms, which extend / retract to adjust the lateral span of the pitch adjustment component 1.

[0024] like Figure 4 The pitch adjustment assembly 1 includes a connecting plate, a connector 12, and an electric push rod 11. The pitch adjustment assembly 1 is connected to the horizontal distance adjustment assembly via a mounting bracket. The connecting plate is rotatably connected to the pitch bracket 15 at one end of the mounting bracket via a rotating shaft, allowing it to rotate around the shaft. The main body of the connector 12 and the connecting plate form a certain angle, with both ends bent. One end is fixed to the connecting plate, and the other end is hinged to the drive end of the electric push rod 11 via a pin 16. The tail end of the electric push rod 11 is hinged to the mounting bracket via a pin 16. The electric push rod 11 and the connector 12 are located on the same side of the connecting plate. The electric push rod 11 acts as a drive component, and the gripping assembly 3 mounted on the connecting plate rotates around the shaft through the push of the connector 12, thereby achieving pitch adjustment to ensure the pitch adjustment range and realize the conversion of the door leaf 4 from flat to upright. The limit switch 13 is fixed to the pitch bracket 15 via screws 17. The limit switch 13 can monitor the flip angle and provide an alarm. The travel limit plate 14 is fixed to the connector 12 via screws 18.

[0025] like Figure 5 The gripping component 3 mainly consists of a suction cup component 31 and a height adjustment component. The suction cup component 31 consists of several suction cups and a mounting plate. An induction switch 32 is provided on the mounting plate between the suction cups. The induction switch 32 is fixed to the mounting plate by screws 37 and is used to indicate whether the suction cup has been properly adsorbed or over-pressured. The mounting plate is L-shaped and the top of the mounting plate is bent.

[0026] The suction cup assembly 31 and the height adjustment assembly are slidably connected. The height adjustment assembly is located on the back of the suction cup assembly 31 and connected to the connecting plate. The height adjustment assembly includes an electric push rod 34, a balancer 35, and a bracket. The balancer 35 is located on both sides of the electric push rod 34. The drive end and tail end of the electric push rod 34 are respectively connected to the top of the mounting plate and the bottom end of the support via pins 36. The drive end and tail end of the balancer 35 are respectively connected to the mounting plate and the bracket. The balancer 35 is a gas spring, which is used to balance the weight of the door leaf during height adjustment. Slider 33 is fixed to both sides of the back of the mounting plate of the suction cup assembly 31 with screws 38. Slide rails are fixed to both sides of the bracket with screws 38. The suction cup assembly 31 and the bracket are slidably connected via slider 33 and slide rails. The bracket is connected to the connecting plate via hexagonal screws 6. The bracket and the connecting plate of the tilt adjustment assembly 1 are connected via hexagonal screws, thus completing the assembly.

[0027] Example 2: Based on Example 1, this example can also have the following variations: the gripping component 3 is connected to the rotation adjustment component 2 and the pitch adjustment component 1.

[0028] The rotation adjustment assembly 2 includes an inner and outer top plate 25 and a slewing bearing 22. The top of the top plate 25 is connected to a connecting plate via hexagonal screws 5, and the bottom is connected to the inner ring of the slewing bearing 22 via screws 28. The bottom of the outer ring of the slewing bearing 22 is connected to a base plate 26 via screws 28. The base plate 26 and the support of the height adjustment assembly are fixed together via hexagonal screws 6. A worm gear DC motor 21 is mounted on the top plate 25. The worm gear DC motor 21 is connected to the top plate 25 via screws 29. The output end of the worm gear DC motor 21 is connected to a pinion 23. The worm gear DC motor 21 drives the slewing bearing 22 to rotate through the pinion 23, thereby driving the gripping assembly 3 to rotate. A limit switch 24 is fixed to the base plate 26 via screws 27 to monitor the rotation angle of the slewing bearing 22 and provide an alarm.

[0029] Taking the door installation process as an example, such as Figure 6The suction cup assembly 31 of the gripping component 3 adsorbs and fixes the door leaf 4. The induction switch 32 is triggered to indicate whether the suction cup assembly 31 has adsorbed properly or if there is overpressure. The suction cup assembly 31 has 4 suction cups, controlled by two sets of vacuum pumps and solenoid valves. At this time, the door leaf is in the initial adsorption state. Then, the worm gear DC motor 21 on the rotation adjustment component 2 drives the pinion 23 to rotate the slewing bearing 22. At this time, the gripping component 3 follows the rotation adjustment component 2 and rotates the door leaf 4 together. The rotation angle is controlled within ±90°. The limit switch... 24 can monitor the rotation angle and provide an alarm. At this time, the door leaf is in the rotation and adsorption state. Finally, the electric push rod 11 on the pitch adjustment component 1 drives the connector 12 to drive the rotation adjustment component 2, the gripping component 3 and the door leaf 4 to flip together. The flip angle is controlled at 100° forward tilt and 15° backward tilt. The limit switch 13 can monitor the flip angle and provide an alarm. The door leaf is in the final installation state. At this time, the electric push rod 34 of the height adjustment component can drive the slider 33 to drive the suction cup component 31 to fine adjust the installation height of the door leaf 4 with an accuracy of millimeters.
