[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Please refer to the appendix. Figures 1-6 The ultrasonic picture frame welding equipment provided by this utility model is used to weld the diagonals of two frame 1s, which are spliced ​​at 90 degrees. It includes a welding table 2, two sets of ultrasonic welding components are fixed on the top of the welding table 2, which are set at 90 degrees. A frame diagonal positioning component is fixed on the top of the welding table 2, which is located between the two sets of ultrasonic welding components. Two sets of frame end positioning components are fixed on the top of the welding table 2, which are set at 90 degrees. A frame pressing positioning component is also fixed on the top of the welding table 2, which is located directly above the two frame 1s.

[0025] Each ultrasonic welding assembly includes an ultrasonic generator 3 and a cylinder mounting plate 4. The ultrasonic generator 3 is fixedly mounted inside the welding table 2. Two cylinder mounting plates 4 are fixed to the rear top and side of the welding table 2, respectively. A first cylinder 5 is fixed to each cylinder mounting plate 4. A transducer mounting flange 6 is fixed to the output shaft of each first cylinder 5. An ultrasonic transducer 7 is fixed to each transducer mounting flange 6. The two ultrasonic transducers 7 are electrically connected to the two ultrasonic generators 3. An ultrasonic welding head 8 is fixed to the end of each ultrasonic transducer 7. It should be noted that the ultrasonic welding head 8 has a built-in amplitude transformer (not shown in the figure). The ultrasonic welding principle is that the ultrasonic generator 3 converts the current into high-frequency electrical energy. The converted high-frequency electrical energy is then converted back into mechanical motion of the same frequency by the ultrasonic transducers 7, and subsequently... The vibration energy is transmitted to the ultrasonic welding head 8 through an amplitude converter that can change the amplitude. The ultrasonic welding head 8 transmits the received vibration energy to the diagonal of the frame 1 to be welded. In this area, the vibration energy is converted into heat energy through friction, melting the diagonal area of ​​the frame 1 to be welded, thus achieving the welding purpose. The two ultrasonic welding heads 8 are set at 90 degrees and are located on both sides of the diagonal of the two frames 1. Specifically, when the two first cylinders 5 are running, the two ultrasonic welding heads 8 can be controlled to move to the diagonal of the two frames 1. Then, by running the ultrasonic generator 3, the ultrasonic welding heads 8 can automatically perform ultrasonic welding on the diagonal of the frame 1, replacing the traditional process of applying glue to the splicing surface and then nailing the frame together. The welding strength is high and the appearance is beautiful, which greatly improves production efficiency and saves labor costs.

[0026] The frame diagonal positioning component includes a vertically arranged second cylinder 9. The top of the second cylinder 9 is vertically fixed to the top of the inner wall of the welding table 2. An angle positioning block 10 is fixed to the top of the output shaft of the second cylinder 9. A right angle groove 11 is opened at the end of the angle positioning block 10. The angle positioning block 10 is located between two ultrasonic welding heads 8. The diagonals of the two frames 1 can abut in the right angle groove 11. Specifically, the right angle groove 11 opened at the end of the angle positioning block 10 can conveniently assist the operator to quickly splice the two frames 1 diagonally at 90 degrees.

[0027] Each set of frame end positioning components includes a slide rail 12. Two slide rails 12 are fixed to the top front end and the side end respectively. The two slide rails 12 are set at 90 degrees. A movable plate 13 slides on each slide rail 12. A strip-shaped sliding hole 14 is opened on each movable plate 13. A first tightening screw 15 is threaded to the end of each movable plate 13. The first tightening screw 15 vertically passes through the strip-shaped sliding hole 14. A first tightening handle 16 is fixed to the top of each first tightening screw 15. It should be noted that a sliding base plate (not shown in the figure) is threaded to the bottom of the first tightening screw 15. The sliding base plate slides linearly at the bottom of the slide rail 12. When the operator rotates the first tightening screw 15 through the first tightening handle 16, the first tightening screw 15 can be controlled to move down. The movable plate 13 can be pressed down through the first tightening handle 16, so that the movable plate 13 is fixed at any position on the slide rail 12. Similarly, rotating in the opposite direction can control the movable plate 13 to move. Therefore, it can be used to position frame 1 of different lengths.

[0028] Positioning plates 17 are slidably installed on the end of the movable plate 13 near the welding table 2. The end of the positioning plate 17 is provided with a 45-degree positioning groove 18. The end of the frame 1 can abut in the 45-degree positioning groove 18, which can conveniently assist the operator to quickly fix the end of the frame 1 manually. The end of the positioning plate 17 near the movable plate 13 is fixed with a guide block 19. The top of the movable plate 13 is fixed with a third cylinder 20. The output shaft of the third cylinder 20 is rotatably connected to a rotating block 21. One end of the rotating block 21 is rotatably connected to the top of the movable plate 13, and the other end of the rotating block 21 abuts against the end of the guide block 19. Specifically, when the third cylinder 20 is running, it can drive the rotating block 21 to rotate. When the rotating block 21 rotates, it can push out the guide block 19 that abuts against it, thereby driving the positioning plate 17 to move a short distance, so as to abut and clamp the end of the frame 1. When used with the right angle groove 11 on the corner positioning block 10, it can effectively ensure the stability of the diagonal splicing of the two frames 1.

[0029] The frame clamping and positioning assembly includes a cylinder mounting bracket 22. The top of the cylinder mounting bracket 22 is fixed to the top of the inner wall of the welding table 2. A fourth cylinder 23 is vertically fixed to the bottom of the cylinder mounting bracket 22. A connecting base plate 24 is fixed to the top of the output shaft of the fourth cylinder 23. Connecting rods 25 are symmetrically and vertically fixed at the top edge of the connecting base plate 24. The tops of the connecting rods 25 all vertically penetrate the top of the welding table 2, and a lower pressure plate 26 is fixed to the top of the connecting rods 25. That is, when the fourth cylinder 23 is running, the lower pressure plate 26 can be driven by the connecting base plate 24 and the connecting rods 25. The lifting and moving mechanism has connecting rods 25 symmetrically arranged on both sides of the diagonal of the two frame 1. The lower pressure plate 26 is threadedly connected to a second tightening screw 27. A second tightening handle 28 is fixed to the top of the second tightening screw 27, and a pressing positioning block 29 is fixed to the bottom of the second tightening screw 27. The bottom of the pressing positioning block 29 can abut against the diagonal of the two frame 1. Specifically, the operator can rotate the second tightening screw 27 through the second tightening handle 28 to control the lifting and lowering of the pressing positioning block 29, thereby performing pressing and fixing positioning work on the diagonal of the two frame 1.

[0030] It should be noted that the device is electrically connected to the external 220V AC mains power through the main controller, and the main controller can be an existing technology device such as a computer (not marked in the figure) for control.

[0031] The usage process of this utility model is as follows: When in use, the operator first controls the second cylinder 9 to move the corner positioning block 10 upward, then the two side frames 1 are placed at 90 degrees and the two side frames 1 are inserted diagonally into the right angle groove 11 for splicing, and the splicing angle is 90 degrees. Then, by moving the two moving plates 13, the end of the side frame 1 is inserted into the 45-degree positioning groove 18 on the positioning plate 17 and the moving plate 13 is locked. Then, the third cylinder 20 is controlled to move and push out the positioning plate 17, that is, to abut and clamp the end of the side frame 1. When used in conjunction with the right angle groove 11 on the corner positioning block 10, the stability of the diagonal splicing of the two side frames 1 can be effectively guaranteed.

[0032] Then, the operator controls the fourth cylinder 23 to move the lower pressure plate 26 downwards, and controls the clamping positioning block 29 to move downwards by rotating the second tightening screw 27, thus clamping and fixing the two frame edges 1 at opposite corners. At this time, the second cylinder 9 moves, controlling the corner positioning block 10 to move downwards, and the first cylinder 5 moves, controlling the two ultrasonic welding heads 8 to abut against the opposite corners of the two frame edges 1. Then, by running the ultrasonic generator 3, the ultrasonic welding heads 8 perform automatic ultrasonic welding on the opposite corners of the frame edges 1, replacing the traditional process of applying glue to the splicing surface and then nailing the frame. This results in high welding strength and a beautiful appearance, greatly improving production efficiency and saving labor costs.

[0033] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
