[0086] The carrier lifting mechanism 3, the welding clamping mechanism 4 and the welding sheet feeding mechanism 6 are respectively arranged on the workbench 1; the carrier lifting mechanism 3 is arranged between the upper welding unit 23 and the lower welding unit 24, and is used to place the transformer and make the transformer terminal in the welding station;

[0087] The welding clamping mechanism 4 is arranged at the front side of the carrier lifting mechanism 3, and the welding clamping mechanism 4 is used to clamp the lead wire and the transformer terminal before welding;

[0088] The feeding mechanism 5 is located at the front side of the welding clamping mechanism 4; the feeding mechanism 5 is used to transport the lead wire to the welding clamping mechanism 4;

[0089] The welding sheet feeding mechanism 6 is arranged at one side of the feeding mechanism 5, and the welding sheet feeding mechanism 6 is used to transport the welding sheet to the welding station.

[0090] The automatic lead welding equipment realizes the operations of lead conveying, solder sheet loading, lead and terminal clamping, and lead and terminal welding through the cooperation of the welding mechanism 2, the carrier lifting mechanism 3, the welding clamping mechanism 4, the feeding mechanism 5 and the solder piece feeding mechanism 6. The whole process is fully automated and does not require manual processing, which saves labor costs and improves production efficiency. It has a high degree of automation, significantly improves welding efficiency, and has stable welding quality.

[0091] Specifically, the welding clamping mechanism 4 includes a bottom lifting drive 41, a bottom lifting seat 42 and a clamping unit 43, and the clamping unit 43 includes a clamping plate 431, a fixing frame 432, a reset member 433, a first clamping member 434 and a second clamping member 435;

[0092] The driving end of the bottom lifting drive 41 is drivingly connected to the bottom lifting seat 42 to drive the bottom lifting seat 42 to rise or fall; the clamping plate 431 is fixed to the front end proximal end of the bottom lifting seat 42; the fixing frame 432 is fixedly arranged on the workbench 1 and is located at the front side of the clamping plate 431;

[0093] The middle parts of the first clamping member 434 and the second clamping member 435 are rotatably assembled on the fixing frame 432 to form a clamp-like structure; the top of the first clamping member 434 and the top of the second clamping member 435 cooperate to form a clamping station for clamping the lead wire and the terminal of the transformer;

[0094] The clamping plate 431 is provided with a guide notch 4310; the width between the two side walls of the guide notch 4310 gradually narrows along the opening edge toward the bottom of the guide notch 4310; the bottoms of the first clamping member 434 and the second clamping member 435 are both rotatably equipped with rollers 436; one end of the reset member 433 is arranged at the proximal end of the lower end of the first clamping member 434, and one end of the reset member 433 is arranged at the proximal end of the lower end of the second clamping member 435, so that the side wall of the roller 436 is close to the side wall of the guide notch 4310.

[0095] The clamping plate 431 is arranged on the bottom lifting seat 42, and will rise or fall with the bottom lifting seat 42. When it is necessary to clamp the lead wire and the terminal of the transformer, the bottom lifting drive 41 drives the bottom lifting seat 42 to rise, thereby driving the clamping plate 431 to rise synchronously. Since the width between the two side walls of the guide notch 4310 gradually narrows along the opening edge toward the bottom of the guide notch 4310, as the clamping plate 431 rises, the spacing between the two rollers gradually decreases, and the reset member 433 is compressed, so that the distance between the top of the first clamping member 434 and the top of the second clamping member 435 gradually decreases, thereby achieving the purpose of the top of the first clamping member 434 and the second clamping member 435 tightening the lead wire and the terminal of the transformer.

[0096] When it is necessary to release the welded lead wire and the terminal of the transformer, the bottom lifting drive 41 drives the bottom lifting seat 42 to descend, thereby driving the clamping plate 431 to descend synchronously. Since the width between the two side walls of the guide notch 4310 gradually narrows along the opening edge toward the bottom of the guide notch 4310, as the clamping plate 431 descends, the reset member 433 drives the bottom of the first clamping member 434 and the second clamping member 435 to reset, and the spacing between the two rollers gradually increases, so that the distance between the top of the first clamping member 434 and the top of the second clamping member 435 gradually increases, so that the top of the first clamping member 434 and the second clamping member 435 release the lead wire and the terminal of the transformer.

[0097] By adopting the above structure, during the welding process, the bottom lifting drive 41 drives the bottom lifting seat 42 and the welding head to move upward or downward, so as to realize the operation of clamping or releasing the lead wire and the terminal of the transformer by the top of the first clamping member 434 and the second clamping member 435; and the structure is simple and the stability is high, which can replace the traditional method of manually adjusting the position of the lead wire and the terminal of the transformer, so that the whole device has a high degree of automation, significantly improves the welding efficiency, and stabilizes the welding quality.

[0098] The fixing frame 432 serves to fix the first clamping member 434 and the second clamping member 435 so that the first clamping member 434 and the second clamping member 435 form a nested structure.

[0099] In a specific embodiment, the reset member 433 is a spring; the reset member 433 can make the side wall of the roller 436 close to the side wall of the guide gap 4310, and reduce or increase the distance between the two rollers 436 through the guide gap 4310 to achieve the purpose of clamping the lead wire and the terminal of the transformer.

[0100] The roller 436 can reduce the friction between the first clamping member 434 and the guide notch 4310 and between the second clamping member 435 and the guide notch 4310, making the clamping and releasing process smoother.

[0137] The unwinding unit 61 is installed at the driving end of the driving unit 64, and the driving unit 64 is used to drive the unwinding unit 61 to move. The movement of the unwinding unit 61 drives the welding sheet feeding unit 63 and the swing unit 62 to move. The movement of the welding sheet feeding unit 63 drives the welding sheet conveyed by the welding sheet feeding unit 63 to move, so as to tear and separate the welding sheet conveyed by the welding sheet feeding unit 63 from the welding sheet welded to the workpiece.

[0138] When the stop sensor 601 senses the swing end of the swing unit 62, the elastic member 603 is in a natural state, and the unwinding unit 61 stops working;

[0139] When the unwinding sensor 602 senses the swinging end of the swinging unit 62, the elastic member 603 is in a stretched state, and the unwinding unit 61 unwinds the welding sheet until the elastic member 603 returns to a natural state.

[0140] By using the unwinding unit 61, driving unit 64, welding sheet feeding unit 63, swinging unit 62, pressure wheel 621, elastic member 603, stop sensor 601 and unwinding sensor 602 in coordination, the welding sheet can be automatically conveyed to the welding workpiece, and after welding is completed, the welding sheet conveyed by the welding sheet feeding unit 63 is torn apart from the welding sheet welded to the workpiece, and then the welding sheet can continue to be conveyed to the next welding workpiece, thereby automatically completing the loading of the welding sheet. During the welding sheet conveying process, the position of the swinging end of the swinging unit 62 is sensed by the stop sensor 601 and the unwinding sensor 602, thereby controlling the unwinding unit 61 to unwind the welding sheet, so that the conveyed welding sheet is always in a tensioned state, thereby ensuring the welding quality.

[0148] When the workpiece needs to be welded, the cylinder 642 drives the unwinding unit 61 to move along the first guide rail pair 643, so that the unwinding unit 61 drives the swinging unit 62 and the welding sheet feeding unit 63 to move, so that the welding sheet transported by the welding sheet feeding unit 63 moves to the workpiece for welding. After welding is completed, the cylinder 642 drives the unwinding unit 61 to move, so that the welding sheet feeding unit 63 is away from the workpiece. Since the welded welding sheet will melt at the workpiece due to heat, the welding sheet transported by the welding sheet feeding unit 63 can be torn apart from the welding sheet welded to the workpiece.

[0149] When the stop sensor 601 senses the swing arm 623, the driving unit 64 stops working. Since the welding sheet is wound on the pressure wheel 621, when the welding sheet feeding unit 63 conveys the welding sheet wound on the pressure wheel 621, the length of the welding sheet between the pressure wheel 621 and the unwinding unit 61 will gradually decrease, thereby driving the pressure wheel 621 to move, so that the swing arm 623 moves to the position of the unwinding sensor 602. At this time, the elastic member 603 is in a stretched state. When the unwinding sensor 602 senses the swing arm 623, the unwinding unit 61 unwinds the welding sheet, so that the length of the welding sheet between the pressure wheel 621 and the unwinding unit 61 gradually increases, and the elastic member 603 gradually returns to its natural state, thereby pulling the swing arm 623 to move until the swing arm 623 moves to the position of the stop sensor 601.

[0150] The unwinding unit 61 is adopted, and the unwinding shaft 614 is driven to rotate by the servo motor 616. The unwinding shaft 614 drives the first limiting plate 612 and the pressing assembly 613 to rotate, thereby driving the welding sheet reel 615 to rotate.

[0151] The welding piece passes through the material guide hole 6340 of the first material guide table 634 and the second material guide table 635 in turn, and then the lifting component 632 is used to drive the material guide driven wheel 6341 to rise and fall to adjust the distance between the material guide driven wheel 6341 and the material guide driving wheel 6342, so that the welding piece can be clamped by the material guide driven wheel 6341 and the material guide driving wheel 6342, and then the rotating component 633 is used to drive the material guide driving wheel 6342 to rotate to transport the welding piece clamped by the material guide driven wheel 6341 and the material guide driving wheel 6342.
