[0028] In order to solve the problem of debris adhering to the surface of the magnetic plate chain, which causes the surface of the magnetic plate chain to be flat and affects the assembly of the transport vehicle, this embodiment adds the following solution on the basis of the first embodiment: See also Figure 8-Figure 11, a debris scraping mechanism 7 is provided in the middle of the upper end of the bottom plate 1, and the debris scraping mechanism 7 includes two supporting plates 701 symmetrically arranged on both sides of the bottom plate 1 and a lifting rod 705 arranged between the two supporting plates 701, and the middle parts of the two supporting plates 701 are provided with a vertical groove 702, and a spring 703 is fixed at the bottom of the vertical groove 702, and the two ends of the lifting rod 705 are respectively slidably limited in the vertical grooves 702 of the two supporting plates 701, and the lower end surface thereof contacts the upper end of the spring 703; a scraper 709 is fixedly provided at the upper end of the lifting rod 705, and the upper end of the scraper 709 contacts the lower end surface of the magnetic plate chain 4; top plates 706 are provided at both ends of the lifting rod 705, and the lower part of the top plate 706 is fixedly installed on the end of the lifting rod 705 by bolts, and the upper part thereof is T-shaped and is in sliding contact with the lower end surface of the magnetic plate chain 4, and the upper width of the top plate 706 is greater than the width of a single magnetic plate 41; When in use, under the action of the spring 703, the lifting rod 705 is always upward, so that the upper end of the scraper 709 is always in contact with the lower end surface of the magnetic plate chain 4, thereby scraping off the attachments on the magnetic plate chain 4. At the same time, the setting of the top plate 706 prevents the scraper 709 from rising excessively, avoiding the upper end of the scraper 709 from being inserted into the connection gap between the two magnetic plates 41 and getting stuck.

[0029] Among them, one side of the scraper 709 is provided with an anti-adhesion mechanism 707, which includes an anti-adhesion plate 7071, a connecting rod 7072 and a core shaft 7073. The interior of the lifting rod 705 is provided with a square hollow cavity, and the side wall of the lifting rod 705 is provided with a plurality of strip-shaped through holes 704.

Because the adhesions on the magnetic plate chain 4 are easily adhered to the scraper 709 after the scraper 709 scrapes them off, the anti-sticking plate 7071 that moves left and right prevents the adhesions from accumulating on the scraper 709 and affecting the scraping effect of the scraper 709. At the same time, the anti-sticking plate 7071 with the magnetic plate 41 can adsorb metal debris adsorbed on the magnetic plate chain 4 to the anti-sticking plate 7071, thereby preventing metal debris from being adsorbed on the magnetic plate chain 4, affecting the flatness of the magnetic plate chain 4, and causing scratches or pits on the surface of the transported automobile assembly components.
