[0015] In summary, the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) A turntable is provided in the middle of the top of the machine, and several workstation fixtures are provided on the edge of the turntable. The several workstation fixtures are distributed in sequence around the edge of the turntable. Thus, the operator can first insert the AC line into the PCB board, then place the PCB board on the workstation fixture, and then use the turntable to rotate the several workstation fixtures in a cycle. (2) A first drive assembly and a second drive assembly are provided on the edge of the top of the machine. The first drive assembly and the second drive assembly are distributed in sequence around the edge of the turntable. The first drive assembly is provided with a first moving plate and the second drive assembly is provided with a second moving plate. The first moving plate and the second moving plate are located above the edge of the turntable so that several workstation fixtures can pass under the first moving plate and the second moving plate in sequence. Thus, under the drive of the turntable, several workstation fixtures will carry the PCB board and pass under the first moving plate and the second moving plate in sequence. Then, the first drive assembly cooperates with the first moving plate to realize the movement trajectory required by the soldering iron tip and the automatic solder wire feeding device. The second drive assembly cooperates with the second moving plate to realize the movement trajectory required by the automatic corner plate and the pressure rod. (3) The first moving plate is equipped with a soldering iron tip and an automatic solder wire feeding device, which can move downwards and perform soldering. The second moving plate is equipped with an automatic angle-folding plate and a pressing rod, which can move downwards and perform folding. Thus, the soldering iron tip and the automatic solder wire feeding device can perform soldering at the connection point between the PCB board and the AC line when moving downwards. After soldering, the plate automatically resets. Then, the automatic angle-folding plate and the pressing rod can bend a part of the PCB board edge when moving downwards. The pressing rod is responsible for pressing down the middle of the PCB board, while the automatic angle-folding plate bends a part of the PCB board edge. After folding, the plate automatically resets. The PCB board and the AC line, which have completed soldering and automatic folding, are removed together so that the workstation fixture can enter the next cycle of work. From this analysis, it can be seen that this utility model can simultaneously perform PCB board soldering and automatic folding, combining the two processes into one, reducing the space occupied by the production line, improving efficiency, and reducing labor costs.

A first moving plate 6 is provided on the first drive assembly 4, and a second moving plate 7 is provided on the second drive assembly 5. The first moving plate 6 and the second moving plate 7 are located above the edge of the turntable 2, so that the several workstation fixtures 3 can pass under the first moving plate 6 and the second moving plate 7 in sequence.

The soldering iron tip 601 and the automatic solder wire feeding device 602 can move downward and perform soldering. An automatic angle-folding plate 701 and a downward pressure rod 702 are provided on the second moving plate 7. The automatic angle-folding plate 701 and the downward pressure rod 702 can move downward and perform angle-folding. Functions: (1) A turntable is provided in the middle of the top of the machine, and several workstation fixtures are provided on the edge of the turntable. The workstation fixtures are distributed in sequence around the edge of the turntable. The operator can first insert the AC line into the PCB board, then place the PCB board on the workstation fixture, and then use the turntable to rotate the workstation fixtures in a cycle. (2) A first drive assembly and a second drive assembly are provided on the edge of the top of the machine. The first drive assembly and the second drive assembly are distributed in sequence around the edge of the turntable. The first drive assembly is provided with a first moving plate, and the second drive assembly is provided with a second moving plate. The first moving plate and the second moving plate are located above the edge of the turntable so that the workstation fixtures can pass under the first moving plate and the second moving plate in sequence.

Thus, the soldering iron tip and the automatic solder wire feeding device can perform soldering on the connection point between the PCB board and the AC line when moving downward. After the soldering is completed, the plate automatically resets. Then, the automatic angle-folding plate and the pressing rod can bend the local edge of the PCB board when moving downward to perform folding. The pressing rod is responsible for pressing down the middle of the PCB board, while the automatic angle-folding plate bends the local edge of the PCB board. After the folding is completed, the plate automatically resets. The PCB board and the AC line after the PCB board soldering and automatic folding are removed together so that the workstation fixture can enter the next cycle of work.Analysis shows that this invention can simultaneously perform PCB board welding and automatic board bending, combining the two processes into one, reducing the space occupied on the production line, improving efficiency, and reducing labor costs.
