Technical Field

[0002] SMT refers to a series of processes performed on PCBs. The feed tray at the feeding station feeds the tape to the placement machine, allowing the machine to complete the placement process. Typically, when the tape in the old tray at the feeding station is about to run out, the operator removes the old tray from the feeding station, takes a new one, and uses a splicer to connect the tape head of the new tray to the tape tail of the old tray. The new tray is then placed in the feeding station to continue loading the tape from the old tray.

[0003] At present, the existing material splicing and unsplicing machines are provided with a material splicing platform, and both ends of the material splicing platform have material guide channels for the new material strip head and the old material strip tail to enter the material splicing platform. In specific applications, it may involve conveying material strips of different widths. However, the spacing of the existing material guide channels is fixed, so only material strips of one width can be guided and conveyed, and the compatibility is poor. Utility Model Content
