[0030] Working principle:

[0031] The light-emitting disk circuit board 901 is placed on the step pin 511 on the rear replacement bracket 51 by means of a manual or external grabbing mechanism, and the light-emitting disk circuit board 901 is positioned and supported by the step pin 511 cooperating with the assembly hole 905; the linear slide 2 4 drives the slide 2 41 to move toward the linear slide 1 2, so that the rear replacement bracket 51 moves to the position of the circuit board clamping mechanism 6, and the front replacement disk 53 moves to the bottom of the linear slide 1 2;

[0032] The linear slide 2 drives the slide 21 to move, and through the cooperation between the linear slide 2 and the telescopic cylinder A311, the finger cylinder 312 clamps the externally supplied connecting nut 903, and places the connecting nut 903 clamped by the finger cylinder 312 in the nut positioning hole 532 on the front replacement plate 53. The nut clamping mechanism 31 repeats the above action to clamp, and cooperates with the driving motor 2 54 to drive the rotating bracket 52 and the front replacement plate 53 to rotate, and places another connecting nut 903 in another nut positioning hole. 532; the cooperation between the linear slide 1 2 and the telescopic cylinder B321 enables the finger cylinder 2 322 to clamp the externally supplied stepper motor 902, and the stepper motor 902 clamped by the finger cylinder 2 322 is placed in the motor positioning groove 531; at the same time, the sliding bracket 63 is moved toward the rear light-emitting disk circuit board 901 through the linear drive mechanism 62, and the clamping claw 67 is driven by the clamping claw cylinder 66 to clamp the light-emitting disk circuit board 901, and the telescopic cylinder D64 is extended to push the slide plate 65 and the light-emitting disk circuit board 901 up;

[0033] When the connecting nut 903 and the stepper motor 902 are positioned, the linear slide 2 4 drives the front replacement disk 53 to move to the bottom of the light-emitting disk circuit board 901, and the telescopic cylinder D64 contracts to place the light-emitting disk circuit board 901 on the upper end of the motor positioning groove 531, so that the light-emitting disk circuit board 901 is attached to the upper end of the stepper motor 902, and the circuit board clamping mechanism 6 returns to its original state; the linear slide 2 4 drives the front replacement disk 53 to move to the bottom of the linear slide 1 2, and the finger cylinder 3 338 clamps the externally supplied fixed ring support 904 through the cooperation of the linear slide 1 2 and the telescopic cylinder C331, and the fixed ring support 904 is moved to the top of the light-emitting disk circuit board 901, and the telescopic cylinder C331 extends to push the lifting plate 332 and the finger cylinder 3 338 down. When the fixed ring support 904 penetrates the light-emitting disk circuit board 901 and the stepper motor 902 and abuts against the connecting nut 903, the connecting nut The reaction force applied by 903 to the fixed ring support 904 overcomes the elastic force of the spring 3311 on the connecting slider 3313, and the lifting plate 332 stops descending, while the telescopic cylinder C331 continues to drive the guide shaft 3314 to descend until the stroke ends; the hollow shaft 335 and the finger cylinder three 338 are driven to rotate by the driving motor 1 333, so as to screw the fixed ring support 904 and the connecting nut 903 for threaded connection. At the same time, when the fixed ring support 904 spirally descends, the elastic force applied by the spring 3311 to the connecting slider 3313 causes the finger cylinder three 338 and the fixed ring support 904 to descend synchronously until the fixed ring support 904 and the connecting nut 903 are threadedly connected, thereby completing the assembly of the light-emitting disk circuit board 901 and the stepping motor 902; after the assembly is completed, the linear slide 2 4 drives the slide 2 41 to move to the next assembly station to carry out subsequent assembly processing on the light-emitting disk circuit board assembly 900.

[0034] Furthermore, a buffer 339 and a limit pin 3310 are fixedly provided on the slide 21 below the lifting plate 332; the buffer 339 has a buffering effect on the downward movement of the lifting plate 332, and the limit pin 3310 has a limiting effect on the downward movement of the lifting plate 332.

[0035] The circuit board and motor assembly device of the vehicle instrument panel disclosed in this embodiment positions and supports the light-emitting disk circuit board 901 by cooperating with the step pin 511 and the assembly hole 905, clamps the connecting nut 903 by the nut clamping mechanism 31 and places it in the nut positioning hole 532 on the front replacement type disk 53, clamps the stepping motor 902 by the motor clamping mechanism 32 and places it in the motor positioning groove 531 on the front replacement type disk 53, and places the light-emitting disk circuit board 901 positioned and supported on the step pin 511 at the upper end of the motor positioning groove 531 by the circuit board clamping mechanism 6, so that the light-emitting disk circuit board 901 fits the front replacement type disk 53. At the upper end of the stepper motor 902, the ring support clamping and screwing mechanism 33 is finally used to clamp and screw the fixed ring support 904 to make it threadedly connected with the connecting nut 903, thereby completing the assembly of the light-emitting disk circuit board 901 and the stepper motor 902; the automation and integration are high, the continuity and coordination of each assembly process are strong, the layout is reasonable, the assembly efficiency of the light-emitting disk circuit board 901 and the stepper motor 902 is high, and the assembly accuracy is high; the spring 3311 and the buffer 339 buffer the impact of the fixed ring support 904 on the connecting nut 903, the impact damage to the light-emitting disk circuit board assembly 900 during assembly is small, and the assembly is stable and reliable.
