The transfer mechanism is mounted on a thin, narrow track belt, the belt driven by a pulley mounted on the edge of the track, by a pulley mounted on the motor driving the inner rail. Both left to right, in the form of belt conveyors, another form of right-to-left, front divided into three parts, and after, before and after the installation of photoelectric sensors in two parts, each input sensor PCB and outgoing (BoardAndling); in PCB central support with a clamp mechanism (Noard Support), in order to ensure the positioning of the PCB during the SMT; the transport mechanism can also adjust the width (Programmable Width Control, PWC) as necessary to accommodate different width of the product sheet.
In the process of the patch, to the plate support by a support PCB warpage, flexibility and minimize slack. In the bottom plate support PCB, above a pin grid array type support positioning mechanism movable amount of the support can be placed in the positioning pin hole in the support plate according to need. When the PCB to guide and transferred to the middle, there will be a backward movement and encounter the stopper to stop the movement, while supporting upstream in the bottom of the PCB board and withstand PCB, PCB clamping mechanism will clamp the middle. When the patch is complete, board support declined, PCB fall, loosen the clamping mechanism, PCB tracks through the following transfer to offline.
