[0010] The technical solution of the present invention is further described below in conjunction with the accompanying drawings:

[0011] Attached Figure 1 It is a front structural schematic diagram of a material feeding detection mechanism of an FPC single pcs appearance inspection machine described in the present invention;

[0012] Attached Figure 2 The present invention is a schematic diagram of the rear structure of a material feeding detection mechanism of an FPC single pcs appearance inspection machine. DETAILED DESCRIPTION

[0013] The present invention will be described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2 As shown, the material feeding detection mechanism of the FPC single pcs appearance inspection machine described in the present invention includes a tray lifting mechanism and a pick-and-place detection mechanism.

[0015] The pallet lifting mechanism includes a loading and unloading base 11, a pallet lifting bracket 12, a pallet lifting platform 13 and a cover lifting platform 14. The loading and unloading base 11 is provided with a lifting frame sliding drive mechanism. The lifting frame sliding drive mechanism drives the pallet lifting bracket 12 to move back and forth on the loading and unloading base 11, so that the pallet lifting bracket 12 can slide in and out of the equipment frame as a whole, which is convenient for loading and unloading operations.

[0016] The pallet lifting bracket 12 is provided with a lifting control mechanism of the pallet lifting platform 13 and a lifting control mechanism of the cover lifting platform 14. The two sets of lifting control mechanisms can control the lifting of the pallet lifting platform 13 and the cover lifting platform 14 separately or synchronously. The two lifting platforms can also share a set of lifting power. The lifting control mechanism can be a motor belt or a motor screw or other mechanism.

[0017] The pallet lifting platform 13 is used to place stacked workpiece pallets, which are common Tray trays with multiple workpiece placement slots for evenly placing multiple FPC single pcs workpieces; the cover lifting platform 14 is used to place pallet covers, which are actually Tray trays stacked in reverse and used to cover the workpiece pallets. After the whole is turned over, the cover and the pallet are swapped so that the cover replaces the pallet to carry the turned over workpiece.

[0018] Figure 2 The reference numerals of the pallet lifting platform 13 and the cover lifting platform 14 in the figure can be interchanged, and there is no mandatory requirement for the inner and outer side positions of the two.

[0019] The tray lifting platform 13 and the cover lifting platform 14 are both provided with tray positioning blocks 16, which facilitate the rapid positioning of the tray and the cover. The sides of the tray lifting platform 13 and the cover lifting platform 14 are both provided with vertical anti-material-slipping baffles 17, which are used to assist in positioning and prevent the tray from slipping out.

[0020] The pallet lifting bracket 12 is provided with a material tray detection sensor 15 above the pallet lifting platform 13 and the cover lifting platform 14. The material tray detection sensor 15 is used to detect whether there are pallets or cover plates on the pallet lifting platform 13 and the cover lifting platform 14, and can issue a material shortage reminder alarm at any time.

[0021] The pick-and-place detection mechanism comprises a detection workbench 21, a pick-and-place moving mechanism 22, a lifting suction cup frame assembly 23, a detection forward movement mechanism 24, a visual detection assembly 25 and a tray entry and exit mechanism 26; the pick-and-place moving mechanism 22, the detection forward movement mechanism 24 and the tray entry and exit mechanism 26 are arranged on the detection workbench 21, and the pick-and-place moving mechanism 22 and the detection forward movement mechanism 24 both adopt a motor screw truss structure. The pick-and-place moving mechanism 22 drives the lifting suction cup frame assembly 23 to move forward and backward, and the detection forward movement mechanism 24 drives the visual detection assembly 25 to move forward and backward. The truss of the detection forward movement mechanism 24 is located above the truss of the pick-and-place moving mechanism 22, and the lifting suction cup frame assembly 23 and the visual detection assembly 25 are one below and one above, and the forward and backward movement does not interfere with each other.

[0022] The lifting suction cup frame assembly 23 includes a lifting cylinder and a suction cup frame. The detection forward movement mechanism 24 is provided with a detection transverse movement mechanism 27, and the detection transverse movement mechanism 27 drives the visual detection assembly 25 to move transversely.

[0023] When the loading inspection station 1 is working, the lifting suction cup frame assembly 23 first grabs the workpiece pallet from the pallet lifting platform 13 and places it on the pallet entry and exit mechanism 26, and then the visual inspection component 25 starts to move forward, backward, left and right to perform visual inspection on all workpieces on the workpiece pallet; an operating table 28 is provided on the front side of the inspection workbench 21, and a display area and an operating area are provided on the operating table 28. The operating area can control the position of the visual inspection component 25, and the display area can provide timely feedback on the inspection results; after the inspection is completed, the lifting suction cup frame assembly 23 grabs the pallet cover from the cover plate lifting platform 14 The plate is placed on the workpiece pallet. The pallet cover not only covers the workpiece pallet, but also presses against the workpiece in the pallet, so that the workpiece is fixed and will not be displaced. Then, each mechanism is reset, and the pallet in-and-out mechanism 26 drives the covered pallet and the cover to move as a whole to the next station. In the visual inspection equipment, the next station is generally the flipping station. The pallet in-and-out mechanism 26 can adopt two sets of motor belt conveyor mechanisms. The conveying direction is generally perpendicular to the grabbing direction of the pallet. The two conveyor mechanisms are respectively equipped with two sides of the pallet and run synchronously. The spacing between the two conveyor mechanisms is adjustable to accommodate pallets of different sizes.
