[0050] This embodiment also includes an automatic soldering machine 37 disposed on the workbench 1.

The rotary drive component 34 in this embodiment is a rotary cylinder.

[0051] The workbench 1 in this embodiment is arranged on a frame 39 , and a plurality of casters 40 are provided at the bottom of the frame 39 , thereby facilitating the movement of the entire wire trimming and soldering machine 100 .

[0052] This embodiment also includes a PLC controller and a touch screen 38 connected to the PLC controller. The rotation drive mechanism 2, the downward linear drive component 6, the ejection linear drive component 10, the pressure sensing component 11, the vertical linear screw module, the wire cutting component 17, the X-axis screw module, the Y-axis screw module, the Z-axis screw module, the rotation drive component 34 and the automatic soldering machine 37 are all connected to the PLC controller.

[0054] This embodiment also includes an alarm connected to the PLC controller. When the pressure value transmitted by the pressure sensor to the PLC controller is not within the normal range, that is, when the pressure value measured by the pressure sensor is less than the normal range, it indicates that the spring 202 in the product is missing, and the alarm will sound an alarm.

[0055] The specific working process is as follows: Step 1, the worker manually inserts the carbon brush 203 and the spring 202 into the brush box 201, then puts the assembled generator carbon brush 203 device 200 into the positioning tool 18, and then places it in the installation hole of the turntable 3.

[0056] Step 2: Control the multi-station divider to rotate the positioning tool 18 and the generator carbon brush 203 device 200 to a station so that it is located below the pneumatic scissors. Adjust the pneumatic scissors to a suitable height through the vertical screw module. At this time, the brush line 204 enters the cutting edge of the pneumatic scissors, and the ejection cylinder rises and ejects. The ejector column 12 is pressed against the tooling slide 189, and the tooling ejector rod 1810 on the tooling slide 189 is pressed against the carbon brush 203. The spring 202 is compressed, and the brush line 204 on the carbon brush 203 rises to a suitable position.

[0057] Step 3: The pneumatic shears trim the wire. Once completed, the vertical screw module resets the pneumatic shears, and the ejector cylinder resets. If the product is missing spring 202, the pressure sensor's output exceeds its normal range, triggering an alarm. When switching between products, the vertical servo motor 15 drives the vertical slider 16 on the vertical screw module to adjust the pneumatic shears to the appropriate height.

[0058] Step 4: After the multi-station divider is controlled to rotate the turntable 3 to another station, the Y-axis servo motor 21 rotates, and the screw nut of the Y-axis ball screw 22 is driven forward through the first pulley 23, the belt 25, and the second pulley 24, driving the electric soldering iron 36 to move forward in the Y-axis direction. After it is in place, the X-axis servo motor 27 rotates, driving the electric soldering iron 36 to move in the X-axis direction. At the same time, the rotary cylinder rotates to a suitable angle. After it is in place, the automatic soldering machine 37 automatically controls the electric soldering iron 36 to solder the first soldering point 206.

[0059] Step 5: After completing the welding of the first soldering point 206, the X-axis servo motor 27 and the Y-axis servo motor 21 drive the soldering iron 36 to the second soldering point 207. At the same time, the rotary cylinder rotates to the same angle in the opposite direction. Once in position, the second soldering point 207 is welded. After welding is completed, the soldering iron 36 is reset and prepared for welding the next product. The Z-axis displacement adjustment is used for height adjustment after changing to another product.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention.
