[0030] A second telescopic cylinder 12 is installed on the frame 2, and a mounting plate 5 is fixed to the end of the output shaft of the second telescopic cylinder 12. A first rotating shaft and a second rotating shaft are installed on the mounting plate 5 through a bearing chamber. A first gear 10 and a second gear are respectively installed on the first rotating shaft and the second rotating shaft. The first gear 10 is meshed with the second gear. The first rotating shaft is fixedly connected to the output shaft of the motor, and the motor is fixedly installed on the mounting plate 5. Brush rollers 6 are fixed to the ends of the first rotating shaft and the second rotating shaft. A gap is left between the brush rollers 6, and the gap is adapted to the shape of the crimping machine cutter head 4.

[0031] A first sensor for detecting position status information of the first telescopic cylinder 11 is installed on the mounting seat 7, and a second sensor for detecting position status information of the second telescopic cylinder 12 is installed on the frame 2. The first sensor and the second sensor are connected to the input module of the PLC through wires, the first telescopic cylinder 11 and the second telescopic cylinder 12 are connected to the cylinder controller, and the cylinder controller is connected to the I / O module of the PLC.

[0032] The working principle of this application is:

[0033] The cable feeding mechanism 8 conveys the cable to the lower part of the crimping machine cutter head 4, and the crimping machine cutter head 4 performs the crimping operation;

[0034] After the crimping machine cutter head 4 completes crimping, it returns to its original position. After returning to its original position, the control system controls the output shaft of the second telescopic cylinder 12 to extend, thereby driving the mounting plate 5 to extend. At the same time, the control system controls the brush roller 6 to rotate through the driving motor. The brush roller 6 cleans the crimping machine cutter head 4 to prevent the crimping machine cutter head 4 from generating an oxide layer or residual stains. After the cleaning is completed, the second telescopic cylinder 12 is delayed to retreat, and the motor of the brush roller 6 stops running.

[0035] During the retraction process of the cable feeding mechanism 8, the control system controls the output shaft of the first telescopic cylinder 11 to extend, thereby driving the friction strip at the end to extend, and the control system controls the transmission belt 13 to rotate in the opposite direction, thereby simultaneously generating a force in the tightening direction on the bolts on the cable feeding mechanism 8, thereby preventing the bolts of the cable feeding mechanism 8 from loosening;

[0036] The operations of tightening the bolts and cleaning the crimping machine cutter head 4 do not require stopping the machine, will not affect the crimping efficiency of the crimping machine, and can effectively prevent the cable feeding mechanism 8 from being misaligned due to loose bolts, and can prevent the crimping machine cutter head 4 from causing terminal adhesion due to oxide layer or stains, causing the terminal to bend upward or downward during crimping.
