Description

Technical Field

[0001] The utility model relates to the technical field of product conveying, in particular to an anti-stuck board conveying line and a reflow soldering production line. Background Art

[0002] In the related art, the transmission line of vacuum reflow soldering is generally provided with multiple sections of guide rails, for example, three sections, and the bare board is dragged and moved on the guide rails by chains, and the bare board will switch between two adjacent sections of guide rails when entering or leaving the vacuum chamber. However, there is a certain distance between two adjacent sections of guide rails, for example, 25mm-50mm. Since the lengths of various bare boards are different, for bare boards with shorter lengths and lighter weight, the friction between the bare board and the chain is smaller. If the bare board cannot accurately enter the second section of the guide rail from the first section of the guide rail, the bare board will interfere at the entry of the chain, thereby causing a board jam, which affects the transportation of the bare board.
