In embodiment 2, the multi-station assembly system directly used for assembling the coating power and free chain is shared by multiple lines with other single-line assembly systems, each single-line multi-station assembly system can meet the assembly requirement of one type or one type of product, a plurality of single-line multi-station assembly systems can meet the assembly requirement of different types of products, each single-line multi-station assembly system is required to be provided with corresponding assembly equipment according to the process characteristics of the assembled products, and the on-line sequence of the coating line frames (vehicle bodies) is required to be according to the general assembly production plan.
Example 4:
referring to fig. 15, in this embodiment, on the basis of embodiment 1, a storage ring 10 for a power and free chain is provided on the power and free chain 1, and a frame is stored on the storage ring 10 for the power and free chain, and the size of the storage space can be determined according to actual needs. When the power and free chain is selected and assembled, the frame body can be selected by utilizing the picking function of the power and free chain, and the power and free chain storage ring can be used for adjusting the frame into a main circuit capable of directly entering the lifter through anticlockwise operation.
Example 5:
referring to fig. 16, this embodiment is where embodiment 3 and embodiment 4 are combined. Because one coating power-free chain 1 corresponds to a plurality of single-wire multi-station operating systems, and the products assembled by each system are different, the assembling beats are different, and therefore, the products are required to be classified and stored on a coating line; the invention arranges a plurality of sets of stacking chain storage rings 10 (according to the number of the assembling subsystems) on the coating stacking chain, thereby greatly meeting the flexible production requirements of sharing a coating line and sorting assembly of multiple products.
In addition, it should be noted that the specific embodiments described in the present specification may vary from part to part, from name to name, etc., and the above description in the present specification is merely illustrative of the structure of the present invention. All equivalent or simple changes of the structure, characteristics and principle according to the inventive concept are included in the protection scope of the present patent. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions in a similar manner without departing from the scope of the invention as defined in the accompanying claims.
