[0038] The tray loaded with the circuit board products after being detected by the detection device can be firstly conveyed to the first tray buffer mechanism 300 through the two conveying belt structures 230 of the tray conveying mechanism 200, and when the circuit board products in the tray are detected to have defective products, the tray with the defective products can be lifted to the first buffer bin 310 by the first tray lifting mechanism 320 for storage; when the circuit board products in the tray are detected to be qualified, the tray can be continuously conveyed to the second tray buffer mechanism 400 by the tray conveying mechanism 200, and the qualified tray can be lifted to the second buffer bin 410 by the second tray lifting mechanism 420 for stacking and storage.

[0039] Further, the cover plate loading and covering mechanism 500 can include a cover plate loading mechanism 510 arranged on the outer side of the rack 100, and a cover plate moving mechanism 520 arranged horizontally on the rack 100, the cover plate moving mechanism 520 being used to move the cover plate on the cover plate loading mechanism 510 to the second buffer bin 410 of each second tray buffer mechanism 400. When the number of trays stacked in the second buffer bin 410 reaches a preset number, one cover plate can be taken from the stacked cover plates on the cover plate loading mechanism 510 by the plate moving mechanism of the cover plate loading and covering mechanism 500, and moved to above the second buffer bin 410 to cover the plurality of trays stacked in the second buffer bin 410; then, the plurality of trays covered with the cover plate in the second buffer bin 410 can be lifted out of the second buffer bin 410 by the second tray lifting mechanism 420, so that the plurality of trays covered with the cover plate fall onto the tray conveying mechanism 200 to be conveyed to the next station. In addition, by arranging the cover plate loading mechanism 510 on the outer side of the rack 100, the cover plate loading mechanism 510 can be connected to an external conveying device (such as an AGV trolley) for automatic movement of the cover plate to the cover plate loading mechanism 510.

[0040] In some embodiments, as shown in FIG. 1, Figures 3 to 5 two tray conveying mechanisms 200 can be arranged side by side on the rack 100, and a first tray buffer mechanism 300 and a second tray buffer mechanism 400 can be arranged in sequence on each tray conveying mechanism 200, and the cover plate moving mechanism 520 can be arranged horizontally above the two second tray buffer mechanisms 400. By arranging two tray conveying mechanisms 200, the detected trays can be conveyed simultaneously by the two tray conveying mechanisms 200 to speed up the conveying speed; further, two sets of first tray buffer mechanisms 300 and second tray buffer mechanisms 400 can be used to buffer and stack the trays that fail the detection and the trays that pass the detection, respectively, to speed up the tray sorting and stacking speed. In addition, one cover plate moving mechanism 520 can automatically take the cover plate from the cover plate loading mechanism 510 and move and cover the plurality of trays stacked in the plurality of second tray buffer mechanisms 400.

[0041] In addition, the tray conveying mechanism 200 can be arranged on the rack 100, and a first tray buffer mechanism 300 and a second tray buffer mechanism 400 can be arranged in sequence on the tray conveying mechanism 200. Alternatively, two or more tray conveying mechanisms 200 can be arranged on the rack 100, and a first tray buffer mechanism 300 and a second tray buffer mechanism 400 can be arranged in sequence on each tray conveying mechanism 200. In addition, a plurality of first tray buffer mechanisms 300 and a plurality of second tray buffer mechanisms 400 can be arranged in sequence on each tray conveying mechanism 200.

[0042] In addition, as shown in Figure 3 The conveying adjusting frame 210 of the tray conveying mechanism 200 can include an adjusting base plate 212 arranged on the rack 100, an extension adjusting member 214 arranged at the middle of the adjusting base plate 212, and two extension guide structures 216 arranged at the two sides of the adjusting base plate 212. The extension adjusting member 214 is connected to the middle of a conveying support frame 220, and the two extension guide structures 216 are respectively connected to the two sides of the conveying support frame 220. The extension adjusting member 214 can drive the conveying support frame 220 to move along the two extension guide structures 216, so as to adjust the distance between the two conveying support frames 220. In addition, by arranging the extension adjusting member 214 at the middle of the adjusting base plate 212 and arranging the two extension guide structures 216 at the two sides of the adjusting base plate 212, the extension driving of the conveying support frame 220 is stable and reliable.

[0043] In addition, the extension adjusting member 214 can include an extension adjusting motor arranged on the adjusting base plate 212, an adjusting transmission belt structure connected to the extension adjusting motor, and an adjusting linear transmission structure connected to the adjusting transmission belt structure. The adjusting linear transmission structure extends along the transverse direction of the adjusting base plate 212 and is connected to the bottom of the conveying support frame 220, so as to drive the conveying support frame 220 to move linearly along the transverse direction of the adjusting base plate 212. In addition, the extension guide structure 216 can include an extension adjusting rail arranged transversely on the adjusting base plate 212, and an extension guide rod arranged side by side on the extension adjusting rail. The bottom of the conveying support frame 220 is slidingly arranged on the extension adjusting rail and movably arranged on the extension guide rod.

[0044] Further, the first storage bin 310 of the first tray storage mechanism 300 can include two limiting plates 312 vertically protruding from the top of the two conveying support frames 220, and a rotating support plate 314 laterally protruding and rotatingly arranged at the bottom of each limiting plate 312. Moreover, the bottom of the limiting plate 312 is provided with a rotating limiting slot, one end of the rotating support plate 314 is rotatably arranged at the bottom side of the rotating limiting slot, and the other end laterally protrudes out of the inner side of the limiting plate 312 (the bottom wall of the rotating limiting slot can limit the rotating support plate 314, so that the rotating support plate 314 can only rotate upward, but cannot rotate downward). The two limiting plates 312 of the first storage bin 310 and the rotating support plate 314 laterally protruding from the bottom of each limiting plate 312 can form a first storage cavity for storing the unqualified trays. When the unqualified trays are stored in the first storage bin 310, the first tray jacking mechanism 320 can jack up the unqualified trays conveyed to the lower side of the first storage bin 310 by the conveyor belt structure 230 of the tray conveying mechanism 200. The unqualified trays will push the rotating support plate 314 to rotate from horizontal to vertical during the upward movement, so that the unqualified trays enter the first storage cavity. When the unqualified trays are jacked up to the upper side of the rotating support plate 314 and separated from the rotating support plate 314, the rotating support plate 314 will be reset from vertical to horizontal. The trays in the first storage cavity can be blocked and limited from the bottom, so as to be stored in the first storage bin 310.

[0045] Further, the second storage bin 410 of the second tray storage mechanism 400 can include a plurality of limiting rods 412 vertically protruding from the top of each conveying support frame 220, and a telescopic support plate structure 414 laterally arranged on each conveying support frame 220, which is located at the bottom of the limiting rod 412. The plurality of limiting rods 412 on both sides and the telescopic support plate structure 414 on both sides can form a second storage cavity for storing the qualified trays. When the qualified trays are conveyed to the lower side of the second storage bin 410 by the tray conveying mechanism 200, the second tray jacking mechanism 420 can jack up the qualified trays conveyed by the two conveyor belt structures 230 of the tray conveying mechanism 200 to the bottom of the second storage bin 410, and make the telescopic support plate structure 414 retract. Then, the second tray jacking mechanism 420 can jack up the qualified trays into the second storage bin 410, and make the telescopic support plate structure 414 extend to the bottom of the qualified trays to support the trays in the second storage bin 410.

[0046] Furthermore, the telescopic support plate structure 414 may include a telescopic bracket 4142 disposed on the conveying support frame 220, a telescopic plate drive member 4144 disposed laterally on the telescopic bracket 4142, and a telescopic support base plate 4146 connected to the telescopic plate drive member 4144. The telescopic plate drive member 4144 is used to drive the telescopic support base plate 4146 to telescopically move so that the telescopic support base plate 4146 is laterally spaced at the bottom of the limiting rod 412. When it is necessary to lift qualified pallets into the second buffer bin 410, the telescopic plate drive 4144 can drive the telescopic support base plate 4146 to retract, so that the second pallet lifting mechanism 420 can lift the qualified pallets into the second buffer bin 410. Then, the telescopic plate drive 4144 can drive the telescopic support base plate 4146 to extend, so as to support and confine the qualified pallets in the second buffer bin 410 from the bottom. Moreover, when it is necessary to transfer multiple pallets stacked in the second buffer bin 410 to the two conveyor belt structures 230 of the pallet conveying mechanism 200 for transport to the next station, the second pallet lifting mechanism 420 can support the multiple pallets in the second buffer bin 410 from the bottom. Then, the telescopic plate drive 4144 can drive the telescopic support base plate 4146 to retract, so that the multiple pallets in the second buffer bin 410 fall onto the second pallet lifting mechanism 420, and then the second pallet lifting mechanism 420 lowers the multiple pallets onto the pallet conveying mechanism 200.

[0047] In addition, such as Figure 6 and Figures 7 to 8 As shown, both the first pallet lifting mechanism 320 and the second pallet lifting mechanism 420 may include a lifting base 322 mounted on the frame 100, a lifting drive 324 mounted on the lifting base 322, a lifting frame structure 326 connected to the lifting drive 324, and a lifting plate 328 arranged side by side on both sides of the lifting frame structure 326. Both lifting plates 328 are located between the two conveyor belt structures 230 and below the first buffer bin 310 or the second buffer bin 410. The lifting drive 324 mounted on the lifting base 322 can drive the lifting frame structure 326 to move up and down, thereby causing the lifting plates 328 on both sides of the lifting frame structure 326 to move up and down. This allows the two lifting plates 328 to move the pallet up and down from both sides, lifting the pallet to the first buffer bin 310 or the second buffer bin 410, or lowering the pallet in the first buffer bin 310 or the second buffer bin 410.

[0048] Furthermore, in some embodiments, the lifting base 322 of the first pallet lifting mechanism 320 and the lifting base 322 of the second pallet lifting mechanism 420 can be integrally formed, connecting the first pallet lifting mechanism 320 and the second pallet lifting mechanism 420 into one unit. This facilitates modular design, ensures structural stability, and allows for easy assembly and disassembly. Moreover, the lifting base 322 of the first pallet lifting mechanism 320 of multiple first pallet buffer mechanisms 300 and the lifting base 322 of the second pallet lifting mechanism 420 of multiple second pallet buffer mechanisms 400 can also be integrally formed.

The feeding seat structure 514 can be used to receive and store multiple cover plates, and the lifting feeding drive 516 can drive the feeding seat structure 514 and the multiple cover plates on it to move up and down, so that the multiple cover plates reach the gripping height of the cover plate transfer mechanism 520. Moreover, by disposing of the feeding seat structure 514 on the outer side of the frame 100, the feeding seat structure 514 can be docked with external conveying equipment (such as AGV trolleys), and can automatically receive cover plate materials conveyed by external conveying equipment, eliminating the need for manual material transfer.

[0050] Furthermore, the feeding seat structure 514 may include a feeding support seat 5142 slidably disposed on the side of the feeding bracket 512, a feeding adjustment structure 5144 disposed on the feeding support seat 5142, two parallel feeding racks 5146 connected to the feeding adjustment structure 5144, and a feeding conveyor belt 5148 disposed on each feeding rack 5146. The two feeding conveyor belts 5148 are used to dock with external conveying equipment to receive materials. The spacing between the two feeding racks 5146 can be adjusted by the feeding adjustment structure 5144, thereby adjusting the spacing between the two feeding conveyor belts 5148, enabling the receiving and conveying of cover plates of different sizes.

[0051] In addition, the cover plate transferring mechanism 520 can include a transferring chassis 522 horizontally arranged on the rack 100, a transferring linear drive module 524 arranged on the transferring chassis 522, a transferring lifting drive module 526 arranged on the transferring linear drive module 524, and a cover plate taking and placing structure 528 arranged on the transferring lifting drive module 526, which is arranged in correspondence with the feeding seat structure 514 and the second buffer bin 410. The cover plate taking and placing structure 528 can be driven to move between the feeding seat structure 514 and the second buffer bin 410 by the transferring linear drive module 524, and the cover plate taking and placing structure 528 can be driven to move up and down by the transferring lifting drive module 526, so that the cover plate taking and placing structure 528 is close to or away from the feeding seat structure 514 or the second buffer bin 410, facilitating the cover plate taking and placing structure 528 to grab the cover plate from the feeding seat structure 514 and transfer the cover plate to the second buffer bin 410 to cover the plurality of trays stacked in the second buffer bin 410.

[0052] The tray buffer and stacking device 10 can automatically stack or store the detected trays, that is, the tray on which the defective product is detected can be automatically stored in the first buffer bin 310 of the first tray buffer mechanism 300, the tray that passes the detection can be automatically stacked and stored in the second buffer bin 410 of the second tray buffer mechanism 400, the plurality of trays stacked and stored in the second buffer bin 410 can be automatically covered with the cover plate by the cover plate feeding and covering mechanism 500, and the plurality of trays covered with the cover plate can be automatically transferred to the tray conveying mechanism 200 and conveyed to the next station by the tray conveying mechanism 200, which not only greatly improves the production efficiency, but also avoids the misplacement of the defective tray and the qualified tray.
