Feeding and grabbing device for sewing sheets of sewn products with different thicknesses Technical Field The invention relates to the technical field of feeding grabbing, in particular to a feeding grabbing device for sewing sheets of sewn products with different thicknesses. Background Some sewn products in the prior art need to sew a plurality of sewing pieces with different thicknesses on the sewn product according to different sewing requirements, using requirements and sewing positions. ( For example, the sewing product such as an automobile air bag is provided with thick piece sewing pieces at the highest stress position of the automobile air bag, so that the stress of the automobile air bag is ensured, and the automobile air bag is provided with thin piece sewing pieces at the lower stress position, so that the automobile air bag is convenient to fold. ) (meanwhile, the description of the background technology does not limit the use of the scheme of the invention, but only exemplifies that some sewed products in the prior art need to be sewn by using sewing pieces with different thicknesses, so as to meet certain sewing requirements, use requirements and functional requirements of different sewing positions. ) Moreover, the sewing technology tends to be more and more automated, so that sewing pieces with different thicknesses on a sewn product is generally performed by adopting automatic feeding, automatic grabbing and automatic sewing. Therefore, in the automatic sewing process, it is extremely difficult to automatically feed the sewing sheets with different thicknesses, and the prior art of automatically feeding the sewing sheets with different thicknesses includes the following steps: 1. The automatic feeding and grabbing mode can cause the increase of the number of the feeding mechanism and the grabbing mechanism, and the mode has the defects of high automatic feeding and grabbing cost and low efficiency; 2. The sewing sheets with different thickness types are firstly detected by adopting a detection sensor and a computer program, then the feeding mechanism and the grabbing mechanism are controlled by the computer program to move by different height distances, so that the sewing sheets with different thickness types are grabbed, but the automatic feeding and grabbing modes need to be detected by adopting the detection sensor to measure distance and then controlled by the computer program, and the mode has the defects of complex debugging of the computer program and high feeding and grabbing cost. The feeding mechanism in the 1 st point and the 2 nd point refers to a mechanism with a single lifting driving mechanism, a feeding sensor and a placing station combination, and the grabbing mechanism refers to a mechanism with a single transferring mechanism, a single taking mechanism and a single placing station combination. Supplementary notes are related to the prior art examples associated with the above point 2, such as: the application publication number is CN103866496A, the technical subject is a Chinese invention patent application of a sewing material detection device for a sewing machine and a presser foot height automatic adjusting system; the application publication number is CN104178940A, the technical subject is a Chinese patent application of a cloth taking device of a full-automatic feeding sewing machine; The application publication number is CN106865091A, the technical subject is a Chinese patent application of an automatic feeding control system and a control method; The application publication number is CN114104658A, the technical subject is a Chinese patent application of a plate feeding self-adaptive control method; The application publication number is CN117142193A, the technical subject is a Chinese patent application of an automatic positioning and grabbing device and a control method thereof; the prior art is characterized in that sensors such as a pressure sensor, an electro-optical distance measuring sensor, a camera module, a laser distance measuring sensor, an ultrasonic distance measuring sensor and the like are relied on to measure different height distances, and then a computer program is combined to control a feeding mechanism to feed materials. Disclosure of Invention The invention aims to overcome the defects in the prior art, and provides a feeding grabbing device for sewing sheets of sewn products with different thicknesses, which is used for simultaneously feeding and grabbing the sewing sheets with different thicknesses, and has the advantages of simpler installation and debugging, low automatic feeding grabbing cost and high automatic feeding grabbing efficiency. In order to achieve the above object, the present invention provides a feeding and grabbing device for sewing sheets of sewn products with different thicknesses, comprising: The feeding mechanism comprises a first frame, a first lifting driving module, a mounting plate and a lifting rod assembly, wherei
