[0027] The specific use process is as follows: first, introduce the tin bar from the outside of the guide tube 4. Before that, the tin bar will pass between the two conveying wheels 8, and the two conveying wheels 8 will also play the role of conveying the tin bar. When working, the tin bar is now fed in from the outside of the machine, and the tin bar passes through the two conveying wheels 8. At the same time, the stepper motor 6 is started, and the stepper motor 6 will drive one of the rotating shaft rods 7 to rotate, and then the current rotating shaft rod 2 7 will drive the corresponding conveying wheel 8 and gear 9 installed thereon to rotate, and then the currently rotating gear 9 will drive the gear 9 on the other rotating shaft rod 2 7 to rotate, and at the same time, the other rotating shaft rod 2 7 will also rotate, and then the other conveying wheel 8 will also rotate, and the two conveying wheels 8 will rotate in the same direction, so that the tin can be The tin bar is transported in the direction of the guide tube 4, and the tin bar will enter the guide tube 4. It should be noted that, under the action of the shape of the guide tube 4, the tin bar can also be guided, so that the tin bar can be accurately aligned with the welding point position of the glasses frame, thereby improving the welding quality of the glasses frame. Then the user places both ends of the glasses frame on the pad 14. At this time, the tin bar is just above the welding point. Then the user steps on the pressure plate 15, and the pressure plate 15 flips downward, and at the same time, the spring 18 is compressed. Among them, the pressure plate 15 is used for the user to step on, so as to finally drive the movable arm 11 to work. When the user steps on the pressure plate 15, the spring 18 will also be compressed. Then after the user releases the pressure plate 15, under the action of the spring 18, the spring 18 can The pressure plate 15 is popped up and reset to prepare for the next use of pressure, which provides convenience for the user. The pressure plate 15 will pull the connecting rod 16 downward, and the connecting rod 16 will pull the connecting rod 2 17 downward, wherein the connecting rod 16 and the connecting rod 2 17 are used to pull the movable arm 11 to move up and down, and are also used to make corresponding adaptations between the pressure plate 15 and the movable arm 11, so as to improve the flexibility and smoothness of the pressure plate 15 when working, and provide convenience for the user's work. Then the connecting rod 2 17 will also drive the movable arm 11 to flip upward, and at this time the welding head 12 will also follow away from the pad 14. Then the user releases the pressure plate 15 that is pressed, and at this time the welding head 12 will automatically fall down under the action of the lever principle, and at the same time the tin bar will also fall onto the frame, When the movable arm 11 is turned upward, the entire positioning assembly 10 will also move accordingly, and when the movable arm 11 falls, it will also fall accordingly, and the positioning rod 101 will also press on the tin bar, so as to ensure that the tin bar is firmly attached to the frame, ensure the smooth progress of the welding work, and provide convenience for the user's work. Under the downward pressure of the positioning rod 101, the tin bar will also drive the guide tube 4 and the rotating shaft rod 3 to make corresponding activities in the fixed frame 2, so as to ensure that the tin bar can be accurately attached to the frame, and because the tin bar itself has a certain toughness, the guide tube 4 will not cause damage to the tin bar when it moves. When the positioning rod 101 presses down the tin bar, it will receive a reaction force from the tin bar.This reaction force will also drive the positioning rod 101 to move up slightly, and the baffle 102 will also move up, while compressing the spring 2 103, and the spring 2 103 will also provide a relative reaction force to push the baffle 102 and the positioning rod 101 down, and finally ensure that the positioning rod 101 is pressed tightly on the tin bar. When the shaft rod 1 3 rotates, the torsion spring 5 will be twisted. Therefore, this reaction force is provided by the torsion spring 5. It should be noted that this compression should be adjusted according to the actual work requirements, so that the tin bar can be pressed tightly and prevented from moving at will, and the tin bar can be moved and fed normally and smoothly.
