[0023] See also Figures 1 to 5 The embodiment of the utility model provides a soldering machine with a workpiece position calibration function, including a workbench 1 and a work frame 2 arranged on the workbench 1, a receiving cavity is reserved in the workbench 1, a rotating column 3 is rotatably arranged in the receiving cavity, a placement plate 4 is fixedly connected to the rotating column 3, an electric push rod 15 is installed on the work frame 2, the electric push rod 15 is fixedly installed on the work frame 2 by bolts, a solder workpiece 16 is installed on the telescopic end of the electric push rod 15, and an electric push rod 2 18 is arranged on one side of the placement plate 4. When the device is used , the electric push rod 15 is used to start the process of driving the soldering workpiece 16 to move away from or close to the placement plate 4. The placement plate 4 is used to place the workpiece to be processed, thereby completing the soldering process. If the workpiece to be processed placed on the placement plate 4 is not in the standard position, the placement plate 4 is driven to rotate by rotating the rotating column 3, thereby driving the workpiece to be processed placed on the placement plate 4 to rotate, and then the electric push rod 2 18 is started, and the telescopic end of the electric push rod 2 18 is used to push the workpiece to be processed placed on the placement plate 4 to adjust its position.

[0024] See also Figures 1 to 5, an adjusting mechanism for changing the position of the electric push rod 2 18 is connected to the electric push rod 2 18, the adjusting mechanism includes a T-shaped support frame 9, an annular frame 10, a connecting column 17 and a driving assembly, the T-shaped support frame 9 is provided with a plurality of mirror-distributed fixed on the working frame 2, the T-shaped support frame 9 is specifically provided with two, which are respectively fixed to two opposite side walls of the working frame 2 by welding, the annular frame 10 is slidably connected to the plurality of T-shaped support frames 9, the interior of the annular frame 10 is provided with an annular slide groove with a T-shaped cross section, and an adaptive sliding connection with the T-shaped support frame 9 can be completed through the annular slide groove. After the connection is completed, the annular frame 10 can rotate, the connecting column 17 is fixed on the annular frame 10, and one end of the annular frame 10 is connected to the electric push rod 2 18, the driving assembly is arranged between the annular frame 10 and the working frame 2, the driving assembly includes an annular rack 11, a second motor 12 and a third gear 13, the annular rack 11 is arranged on the annular frame 10, the second motor 12 is installed on the inner wall of the working frame 2, and the third gear 13 is installed on the inner wall of the working frame 2. 13 is installed at the output end of the motor 2 12, and the gear 3 13 is meshed with the annular rack 11. When in use, the device starts the motor 2 12 to rotate clockwise or counterclockwise, thereby driving the gear 3 13 to rotate, thereby driving the annular rack 11 meshed with the gear 3 13 to move, and because the annular rack 11 is fixedly connected to the annular frame 10, the annular frame 10 will also rotate at this time, thereby driving the connecting column 17 to move, so that the electric push rod 2 18 is driven, thereby completing the adjustment structure. Through the above method, the position of the electric push rod 2 18 can be driven to adjust, and with the rotation of the placement plate 4, the standard position correction of the workpiece to be processed in the non-standard processing position on the placement plate 4 can be completed, thereby improving the processing accuracy of the device and reducing the situation where the processing accuracy is reduced due to the workpiece to be processed not being in the standard position. At the same time, thanks to the cooperation of the electric push rod 2 18 and the placement plate 4, the device has a wide adjustable range for the workpiece to be processed and is more practical.

[0025] See also Figures 1 to 5 A driving mechanism for rotating the rotating column 3 is arranged in the accommodating cavity, and the driving mechanism includes a gear 15, a gear 26 and a motor 17. The gear 15 is sleeved on the rotating column 3, and the motor 17 is arranged on one side of the rotating column 3. The gear 26 is connected to the output end of the motor 17, and the gear 26 is meshed with the gear 15. When the device is used, the motor 17 is started to drive the gear 26 to rotate clockwise or counterclockwise. Since the gear 26 is meshed with the gear 15, when the gear 26 rotates, the gear 15 will also rotate, thereby driving the placement plate 4 arranged on the gear 15 to rotate, thereby completing the driving process.

[0026] See also Figure 1A PLC controller 14 is provided on one side of the motor 2 12. The PLC controller 14 is electrically connected to the electric push rod 1 15, the solder processing part 16, the electric push rod 2 18, the motor 1 7 and the motor 2 12.

The electric push rod 1 15, the solder processing part 16, the electric push rod 2 18, the motor 1 7 and the motor 2 12 are controlled by the PLC controller 14.

[0027] See also Figure 4 A dustproof plate 8 for closing the accommodating cavity is installed on the side wall of the workbench 1. The dustproof plate 8 is fixed to the side wall of the workbench 1 by bolts. The dustproof plate 8 is used to close the accommodating cavity. While allowing the accommodating cavity to exchange air with the external environment, the motor 7 can dissipate heat. The internal space of the accommodating cavity can be operated by removing the bolts, so that the internal parts can be inspected or other work can be carried out. At the same time, it can reduce the entry of external dust and other impurities into the accommodating cavity, thereby improving the service life of the device.

By starting the motor 2 12 to rotate clockwise or counterclockwise, the gear 3 13 is driven to rotate, thereby driving the annular rack 11 meshing with the gear 3 13 to move. Since the annular rack 11 is fixedly connected to the annular frame 10, the annular frame 10 will also rotate at this time, thereby driving the connecting column 17 to move, so that the electric push rod 2 18 is driven, thereby completing the adjustment structure. In the above manner, the position of the electric push rod 2 18 can be adjusted. Starting motor 17 drives gear 2 6 to rotate clockwise or counterclockwise. Since gear 2 6 is meshingly connected to gear 1 5, when gear 2 6 rotates, gear 1 5 will also rotate, thereby driving the placement plate 4 set on gear 1 5 to rotate. In coordination with the rotation of the placement plate 4, the electric push rod 2 18 is started, and the telescopic end of the electric push rod 2 18 pushes the workpiece to be processed placed on the placement plate 4 to adjust its position. The workpiece to be processed in the non-standard processing position on the placement plate 4 can be corrected to the standard position, and then the electric push rod 15 is started to drive the solder processing workpiece 16 to move away from or close to the placement plate 4, thereby completing the soldering process.
