[0002] Components with double-sided terminals play an important role in electronic circuits. The characteristic of these components is that they have electrode terminals from both sides, that is, both sides have electrode leads. Common components with double-sided terminals include capacitors, inductors, diodes, transistors, etc. During the processing of double-sided terminals, both electrode surfaces of the terminals need to be welded and connected to wires.

[0022] See also Figure 1-Figure 4 As shown, the utility model is a double-sided terminal welding machine, comprising a frame 1, a clamping assembly for clamping and positioning a double-sided terminal 100 is installed on the front side of the frame 1, a lower welding assembly is fixedly installed below the clamping assembly, a lifting drive assembly installed on the upper end of the frame 1 is arranged above the clamping assembly, and an upper welding assembly located above the clamping assembly is fixedly installed at the bottom end of the lifting drive assembly;

[0023] During welding, firstly, a wire is placed on the top of the lower welding assembly, and then the double-sided terminal 100 is placed on the top surface of the wire. At the same time, the double-sided terminal 100 is clamped and positioned by the clamping assembly, and then another wire is placed on the top surface of the double-sided terminal 100. Then, the upper welding assembly is driven downward by the lifting drive assembly, so that the bottom end of the upper welding assembly is abutted against the top of the upper wire, so that the double-sided terminal 100 is clamped and positioned between the two wires by the cooperation of the upper welding assembly and the lower welding assembly, and finally, the upper and lower surfaces of the double-sided terminal 100 are welded by the upper welding assembly and the lower welding assembly respectively, so that the double-sided terminal 100 is welded and connected with the two wires at the same time;

[0024] Among them, the upper and lower sides of the double-sided terminal 100 are welded simultaneously by two sets of upper and lower welding components, without welding the two sides of the double-sided terminal 100 one by one, which simplifies the welding steps of the double-sided terminal 100 and improves the welding processing efficiency of the double-sided terminal 100.

[0025] Specifically, the lower welding assembly and the upper welding assembly each include an ultrasonic transducer 2, an horn 3 and a welding head 4, the ultrasonic transducer 2 is fixedly connected to the welding head 4 through the horn 3, and the welding head 4 in the lower welding assembly is vertically fixedly installed at the bottom end of the frame 1, and the welding head 4 in the upper welding assembly is vertically fixedly installed at the bottom end of the lifting drive assembly;

[0026] The lifting drive assembly includes a pneumatic lifting shaft 6 and a lifting guide rail 8. The pneumatic lifting shaft 6 is fixedly mounted on the top of the frame 1. The lifting guide rail 8 is fixedly mounted on the side wall of the frame 1. A lifting slide 7 is slidably mounted in the lifting guide rail 8. The telescopic end at the bottom of the pneumatic lifting shaft 6 is fixedly connected to the top of the lifting slide 7.

[0027] During welding, the lower wire is placed on the top of the lower welding head 4, and then the upper wire of the double-sided terminal 100 is placed in sequence. Then, the lifting slide 7 is driven downward along the lifting guide rail 8 by the pneumatic lifting shaft 6, thereby driving the upper welding head 4 downward until the upper welding head 4 abuts against the top of the upper wire. After that, the welding assembly and the upper welding assembly start working synchronously, and the double-sided terminal 100 is ultrasonically welded by the cooperation of the ultrasonic transducer 2, the amplitude transformer 3 and the welding head 4.

[0028] Specifically, the clamping assembly includes a pneumatic telescopic shaft 5, a fixed clamping block 9 and a movable clamping block 10, the fixed clamping block 9 is fixedly installed on the front side of the frame 1, the movable clamping block 10 is arranged on one side of the fixed clamping block 9, and the movable clamping block 10 is slidably installed on the frame 1 through a guide rail, the pneumatic telescopic shaft 5 is fixedly installed on the front side of the frame 1, and the telescopic end of the pneumatic telescopic shaft 5 is fixedly connected to the outer end of the fixed clamping block 9; the lower end of the frame 1 is provided with a fixture plate 11 located on one side of the clamping assembly, the top surface of the fixture plate 11 is provided with a fixture groove 12, and the bottom end of the fixture plate 11 is installed with a spring support shaft 13;

[0029] When the double-sided terminal 100 is clamped and placed, the main body of the double-sided terminal 100 is first clamped into the fixture groove 12 on the top surface of the fixture plate 11 to preliminarily position the double-sided terminal 100, and the welding position of the double-sided terminal 100 extends between the fixed clamp block 9 and the movable clamp block 10, and then the movable clamp block 10 is driven to move toward the fixed clamp block 9 by the pneumatic telescopic shaft 5, so that the movable clamp block 10 cooperates with the fixed clamp block 9 to abut and limit the two sides of the welding position of the double-sided terminal 100, and the jig plate 11 is operated by the spring support shaft 13, so that the upper welding head 4 moves downward to weld the double-sided terminal 100. During this process, if the welding head 4 moves the double-sided terminal 100 downward, the double-sided terminal 100 can move the jig plate 11 downward synchronously, so that the double-sided terminal 100 has a certain degree of automation during welding, which is beneficial to improving the firmness of the welding connection between the double-sided terminal 100 and the wire.
