Embodiment

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.

As Fig. 1, shown in Fig. 2, copper post pick-up unit for a kind of LED display, comprise base 2, be arranged on respectively the clamp assemblies 4 at base 2 two ends and be crossed on the portal 6 on base 2, on portal 6, be fixed with cylinder 8, controller 10, cylinder 8 is connected with probe assembly, probe assembly comprises framework, the cross bar 12 moving forward and backward along framework and the probe moving left and right along cross bar 12, preferably framework comprises the rectangle support body 14 of hollow, be arranged on the vertical pole 16 on support body 14, cylinder 8 is fixedly connected with vertical pole 16, the two ends of cross bar 12 snap in respectively in support body 14 and vertical pole 16, the first draw-in groove (not shown) can be all set on support body 14 and vertical pole 16, cross bar 12 can move forward and backward along the first draw-in groove of support body 14 and vertical pole 16 adjusts position, probe comprises probe body 18, be located at the projection 20 of probe body 18 1 sides, probe body 18 is metal material and one-body molded with projection 20, survey precisely, the second draw-in groove (not shown) can be set on cross bar 12, probe body 18 can move left and right and adjust position along cross bar 12, cross bar 12, the equal adjustable position of probe body 18, be convenient to the detection of the copper post of the diverse location on the pcb board of applicable different size, applied widely, for fear of probe body 18, from cross bar 12, drop greatly because of acting force, the utility model preferred probes body 18 is T-shaped, the width of the head of probe body 18 is greater than the width of the second draw-in groove, probe body 18 is provided with pressure transducer 22, pressure transducer 22 is connected with controller 10, for detection of the firm welding whether of the copper post on pcb board.
