[0019] The fixed connection mechanism is installed on the base plate 1; the lifting mechanism is cooperatively installed on the fixed connection mechanism, for realizing the lifting of the overall mechanism; the rotating mechanism is cooperatively installed on the lifting mechanism, for realizing the angle adjustment of the transmission mechanism; the transmission mechanism is cooperatively installed on the rotating mechanism, for realizing the conveying of the vehicle body panel. The overall mechanism realizes the lifting through the telescopic stroke of the first electric cylinder 3.4, and realizes the movement through the connecting rod mechanism consisting of the first rotary connecting piece 4.1, the first pin shaft 4.2, the second rotary connecting piece 4.3, the second pin shaft 4.4, the CLAMP plate 4.6, the second connecting piece 4.11, the third pin shaft 4.12, the cylinder connecting head 4.13 and the third connecting piece 4.15 controlled by the telescopic stroke of the second electric cylinder 4.8, so as to realize the transmission angle change of the mechanism. The conveying of the mechanism is powered by the driving assembly 5.1 to drive the overall transmission mechanism to realize the conveying of the panel.

[0020] The fixed connection mechanism is shown in detail Figure 2The fixed support 2.1, the leveling bolt 2.2, the first connecting piece 2.3, the photoelectric switch 2.4 and the photoelectric switch mounting bracket 2.5 are composed. The photoelectric switch 2.4 is mounted on the photoelectric switch mounting bracket 2.5, and both are mounted on the fixed support 2.1 by bolts, which is used for detecting the body panel. The fixed support 2.1 is mounted on the base plate through the leveling bolt 2.2 and the first connecting piece 2.3.

[0021] The lifting mechanism is shown in detail Figure 3 The lifting support 3.1, the lifting guide assembly 3.2, the first motor 3.4, the first electric cylinder 3.4 and the first mounting connecting seat 3.5 are composed. The first motor 3.3 and the first electric cylinder 3.4 are mounted on the fixed connecting mechanism through the first mounting connecting seat 3.5. The lifting guide assembly 3.2 is mounted on the fixed connecting mechanism, and works with the first electric cylinder 3.4 to control the lifting. The lifting support 3.1 is mounted on the lifting guide assembly 3.2 and the first electric cylinder 3.4, and the other end is connected with the rotating mechanism, so as to realize the overall lifting of the mechanism.

[0022] The rotating mechanism is shown in detail Figure 4 And Figure 5 The first rotating connecting piece 4.1, the first pin shaft 4.2, the second rotating connecting piece 4.3, the second pin shaft 4.4, the first proximity switch 4.5, the CLAMP plate 4.6, the second mounting connecting seat 4.7, the second electric cylinder 4.8, the parallel mounting assembly 4.9, the second motor 4.10, the second connecting piece 4.11, the third pin shaft 4.12, the cylinder connecting head 4.13, the first proximity switch mounting bracket 4.14, the third connecting piece 4.15 and other components are composed. The whole rotating mechanism is mounted on the lifting mechanism through the second connecting piece 4.11. The second electric cylinder 4.8, the parallel mounting assembly 4.9 and the second motor 4.10 are mounted on the second connecting piece 4.11 through the second mounting connecting seat 4.7, which constitutes the power assembly of the mechanism. The CLAMP plate 4.6 is connected to the cylinder connecting head 4.13 through the third pin shaft, the first rotating connecting piece 4.1 is mounted on the CLAMP plate 4.6, and the second rotating connecting piece 4.3 is mounted on the second connecting piece 4.11. The first rotating connecting piece 4.1 and the second rotating connecting piece 4.3 are connected to the third connecting piece 4.15 through the first pin shaft 4.2 and the second pin shaft 4.4 respectively, which constitutes a connecting rod mechanism. The whole rotating mechanism is connected with the transmission mechanism through the third connecting piece 4.15. When the second electric cylinder 4.8 extends and retracts the cylinder rod, the transmission angle of the whole mechanism is changed through the movement of the connecting rod mechanism, so as to realize the change of the transmission angle of the whole mechanism. The first proximity switch 4.5 is mounted on the second connecting piece 4.11 through the first proximity switch mounting bracket 4.14, which is used for detecting whether the transmission angle of the mechanism is in place.

[0023] The transmission mechanism is shown in detail Figure 6The driving assembly, the conveying belt, the second proximity switch, the second proximity switch mounting bracket, the driven assembly and the aluminum alloy track are composed. The conveying belt 5.2 and the second proximity switch 5.3 are both mounted on the aluminum alloy track 5.6. When the second proximity switch 5.3 detects that the vehicle body panel is in place, a signal is sent, the driving assembly 5.1 provides power and works together with the driven assembly 5.5 to drive the whole transmission mechanism to convey the vehicle body panel.

[0024] In work, the belt transmission mechanism can change the height and angle of the transmission mechanism according to the vehicle model information transmitted by the previous station through the PLC system to control the first electric cylinder 3.4 and the second electric cylinder 4.8 to extend the corresponding stroke. At this time, the first proximity switch 4.5 detects that the vehicle model switching angle is in place, sends a part signal to the previous station, and at the same time, the driving assembly 5.1 starts to work to drive the transmission belt 5.2 to rotate. When the panel is transmitted to the station, the second proximity switch 5.3 senses that there is a part, and after the panel is transmitted in place, the photoelectric switch 2.4 has a signal, the next station sends a part signal to the station, and after the station receives the part signal, the next station sends a part transmission signal to the next station. The transmission belt 5.2 drives the panel to move forward and enter the next station. When the workpiece is in place, the next station sends a stop signal to the station, the photoelectric switch 2.4 and the second proximity switch 5.3 have no signal, the driving assembly 5.1 stops working, and starts to wait for the next round of work signal.

[0025] It should be noted that, for those skilled in the art, without departing from the principle of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
