[0026] Example 1

[0027] Such as Figure 1-2 As shown, the present invention provides an automated ultrasonic flexible welding system, including: an ultrasonic welding mechanism, a welding station, a mold changing cart 6 and a safety fence 7. The ultrasonic welding mechanism includes: a welding robot 1, an ultrasonic welding device 2, and The welding gun library 3, the welding robot 1 is fixedly installed by the robot mounting frame, and the welding robot 1 is connected with the ultrasonic welding device 2. In order to speed up the welding process, two sets of welding robots 1 are set in this embodiment to Partition synchronous welding is performed. The welding gun library 3 is arranged in the middle position of one side of the two groups of welding robots 1 for placing welding guns of different specifications, and the welding station is arranged between the two groups of welding robots 1 On the other side, the welding station includes: a welding workbench frame 4 and a positioning and pressing device 5 provided on the welding workbench frame 4, the positioning and pressing device 5 is used to install a workpiece, and the replacement The mold trolley 6 is used to replace the positioning and pressing device 5, the safety fence 7 is arranged on the periphery of the ultrasonic welding mechanism and the welding station, and the robot control cabinet 8 and the electric cabinet 9 are arranged on the outer side of the safety fence 7 And touch screen 10.

[0029] On the basis of the above embodiment, further, such as Figure 5 As shown, the ultrasonic welding device 2 includes: a welding head adjustment assembly and a quick-change welding head assembly, the welding head adjustment assembly and the quick-change welding head assembly are connected by a quick-change chuck, and the welding head adjustment The components include: sliding table cylinder 20, chuck connecting plate 21 and chuck body R side 22, which are connected in sequence from top to bottom. The quick-change welding head assembly includes: chuck body T side 23, welding gun mounting plate 24. Welding head mounting frame 25, amplitude modulator and transducer 26, and welding head 27, the chuck body T side 23 is connected to the chuck body R side 22, and the welding gun mounting plate 24 is mounted on the chuck Below the T side 23 of the disc body, the side end of the welding gun mounting plate 24 is connected to the welding head mounting frame 25, and the amplitude modulator and transducer 26 are mounted on the welding head mounting frame 25. The welding head 27 is mounted on the lower end of the amplitude modulator and the transducer 26, the sliding table cylinder 20 is mounted on the cylinder mounting plate 28, and the end of the cylinder mounting plate 28 is fixedly connected to the robot connecting plate 29. The robot connecting plate 29 is connected to the welding robot 1, and the quick-change welding head assembly is driven to perform a reciprocating linear motion as a whole through the sliding table cylinder 20.

[0030] Wherein, a position sensor 30 is installed on one side of the sliding table cylinder 20, and the position sensor 30 is used to feed back the extension distance of the sliding table cylinder 20 to effectively control it to provide a suitable pressure.

[0031] In addition, in order to detect whether the chuck body R side 22 and the chuck body T side 23 are installed in place during the quick replacement of the quick-change welding head assembly, on the side of the chuck body R side 22 A proximity switch 36 is installed at the end, and a detection block 37 used in conjunction with the proximity switch 36 is installed at the side end of the T side 23 of the chuck body.

[0032] Example 3

[0033] On the basis of the above embodiment, further, such as Figure 3-4 As shown, the welding gun library 3 is composed of a base 31 and a welding gun fixing plate 32 installed above the base 31. The welding gun fixing plate 32 is provided with four groups of welding gun holder blocks 33 side by side, and the welding gun mounting plate Two positioning holes 241 are symmetrically provided on the end of the welding head mounting frame 25 on the side 24, and two locating holes 241 are symmetrically provided on both sides of the welding torch block 33 of each group. Positioning pins 34. A detection sensor 35 is also provided between each set of positioning pins 34 on the welding gun fixing plate 32 for detecting whether the quick-change welding head assembly is placed at this position. The welding gun mounting plate 24 An avoidance coordinated with the detection sensor 35 is provided.
