It should be noted that the moving mechanism 430 includes a loading and unloading frame 431, a slide 432, and a third linear moving mechanism 433; the first material taking arm 410 and the second material taking arm 420 are arranged on the sliding base 432, and the sliding base 432 is transversely arranged on the upper and lower side frames 431 in a sliding manner relative to the license plate conveying plate 310; the third linear moving mechanism 433 is in transmission connection with the sliding base 432 and is used for driving the sliding base 432 to move linearly transversely relative to the license plate conveying plate 310. Therefore, the third linear moving mechanism 433 drives the sliding base 432 to slide on the upper and lower material side frames 431, so as to drive the first material taking arm 410 and the second material taking arm 420 to move, and further, the moving mechanism 430 drives the first material taking arm 410 and the second material taking arm 420 to move linearly and transversely relative to the license plate conveying plate 310 in a linkage manner, so that the license plate conveying device has the advantages of simple structure and convenience in control. It should be noted that the third linear driving mechanism may be a linear driving module such as a cylinder driving module, a hydraulic cylinder driving module, a linear motion module or a ball screw linear transmission mechanism, and has the advantages of convenient control and stable motion output.
Specifically, the first material taking arm 410 and the second material taking arm 420 respectively comprise a telescopic cylinder 411 and a suction cup 412, and the suction cup 412 is arranged at the telescopic end of the telescopic cylinder 411. So, drive the sucking disc 412 that is located its flexible tip through telescopic cylinder 411 and stretch out and draw back, utilize sucking disc 412 to adsorb the license plate, realize that first arm 410 of getting and second arm 420 of getting grabs the license plate, accomplish the last unloading step of license plate, simple structure, control is convenient.
