Detailed Description

As shown in figure 1, the membrane switch embossing device comprises two groups of turntables I1, a motor I2, a chain 3, a lower die 8 and an upper die 9. The two groups of turntables I1 are fixed on the inner wall of the case 4 through rotating shafts; wherein the pivot of a set of carousel I1 and motor I2's output shaft, motor I2 fixes at 4 lateral walls of quick-witted case, sets up the workbin 10 that connects in this set of carousel I1 below to set up carousel II 5 in this set of carousel I1 top. The rotating shaft of the rotating disc II 5 is connected with the output shaft of the motor II 6, and the motor II 6 is fixed on the outer side wall of the case 4. Motor I2 and motor II 6 are driven by PLC controller 16, and PLC controller 16 sets up at quick-witted case 4 lateral wall.
