Description

Technical Field

[0002] In the manufacturing process of electronic materials, visual inspection equipment is needed to inspect the appearance of the materials, including front and back inspection. Currently, multiple materials are usually transferred to various processes of the visual inspection equipment by carrying them on a pallet. After the materials in the pallet are inspected, they need to be sorted by sorting equipment according to the inspection results.

[0003] Existing visual inspection equipment requires double-sided inspection of materials during the inspection process. As a result, the materials in the pallet are in the reverse side after inspection. This necessitates flipping the materials in the pallet before sorting to adjust their orientation so that the right side is facing up. Consequently, existing visual inspection and sorting equipment cannot achieve continuous production, resulting in low efficiency in material inspection and sorting. Summary of the Invention

[0015] Compared with existing technologies, the pallet-based material detection and sorting integrated machine proposed in this application has the following advantages: 1) By setting a first flipping device between the first detection device and the second detection device and a second flipping device between the second detection device and the sorting device, the material in the pallet is flipped over as a whole while the pallet is being transported between the devices, thus achieving continuous production and improving the detection and sorting efficiency of the material. 2) The first and second trays are equipped with material troughs on both sides, so that the second tray can be automatically converted into the first tray at the waiting station, which further improves the continuity of material turning and work efficiency. 3) Tightening components are respectively provided on the first clamping member and the second clamping member. After clamping the pallet, the tightening components, together with the corresponding limiting members, tighten and fix the side of the corresponding pallet, thereby achieving dual fixation of the pallet sidewall clamping and side tightening. The fixing effect is good and effectively prevents the corresponding pallet from shifting during the flipping process. 4) The second type of pallet is transported to the fourth conveyor via the handling mechanism. The first type of pallet, the second type of pallet, and the empty pallet are then transported to the sorting mechanism via the corresponding conveyor. The sorting mechanism moves the non-conforming products in the first type of pallet to the empty space of the second type of pallet or to the empty pallet, and moves the conforming products in the second type of pallet to the empty space of the first type of pallet. This greatly reduces the number of times the sorting mechanism handles the products in the pallet and improves the sorting efficiency. 5) The inspected pallets are divided into Category 1 pallets with a higher percentage of qualified products and Category 2 pallets with a higher percentage of unqualified products. Category 1 pallets are directly sent to the sorting mechanism via the third conveyor mechanism, while Category 2 pallets are transported to the fourth conveyor mechanism via the handling mechanism and then sent to the sorting mechanism. The sorting mechanism then sorts the pallets, which achieves the classification and diversion of pallets with high and low defect rates, significantly improving the overall material sorting efficiency.

The first drive assembly 420 is configured to drive the first clamping member 422 and the second clamping member 423 to move closer to or further away from each other, so as to clamp or release the opposite two side walls of the first tray 11 and / or the second tray 21.

[0038] Specifically, the drive mechanism 41 is also configured to drive the clamping mechanism 42 to rise and fall. The drive mechanism 41 includes a base 410, a fifth drive component 411, and a sixth drive component 412. The fixed end of the fifth drive component 411 is disposed on the base 410, and the flipping frame 421 is rotatably disposed on the base 410.

[0039] Specifically, the fifth drive component 411 is a rotary drive module that uses a motor and a coupling.

[0040] Specifically, the sixth drive component 412 adopts a conventional lifting drive module.

[0041] Specifically, the drive end of the first drive component 420 is connected to the first clamping member 422 and the second clamping member 423.

[0042] Through the cooperation of the first drive assembly 420, the flipping frame 421, the first clamping member 422 and the second clamping member 423, a clamping mechanism 42 that provides stable, precise and simple clamping is provided.

[0043] In one embodiment, the clamping mechanism 42 further includes two sets of positioning components, which are respectively disposed on the first clamping member 422 and the second clamping member 423. The positioning components include a limiting member 424 and at least one set of clamping components 425.

The clamping components 425 are configured to clamp and fix the side of the corresponding tray to the limiting member 424 after the first clamping member 422 and the second clamping member 423 clamp the corresponding tray and before the driving mechanism 41 drives the flipping frame 421 to flip.

[0044] Specifically, the limiting member 424 is a boss extending along the length of the clamping surface. The boss is set on the first side of the clamping surface of the corresponding first clamping member 422 or second clamping member 423. The cylinder is installed on the second side of the clamping surface of the corresponding first clamping member 422 or second clamping member 423. The limiting surface of the boss is a plane, which ensures stable contact with the corresponding pallet and uniform force distribution. This not only further ensures the stability of the pallet when it is clamped, but also has a simple structure.

[0045] Specifically, there are two sets of clamping components 425. The two sets of clamping components 425 are spaced apart along the length of the clamping surface to achieve multi-point synchronous clamping on the side of the pallet. The clamping is more uniform and the force is more balanced, avoiding uneven force on the corresponding pallet due to single-point clamping, which may cause it to shift or even be damaged. This ensures accurate and reliable positioning throughout the flipping process.

[0046] Specifically, each clamping assembly 425 includes a mounting plate, a first cylinder, and a clamping member. The mounting plate is fixedly mounted on the corresponding first clamping member 422 or second clamping member 423.

The clamping member is mounted on the driving end of the first cylinder, and the first cylinder drives the clamping member to move closer to or away from the limiting member 424.

[0047] Specifically, the clamping component is a clamping rod, which is coaxial with and fixedly installed with the corresponding first cylinder.

[0048] By setting clamping components 425 on the first clamping member 422 and the second clamping member 423 respectively, after clamping the pallet, the clamping components 425 cooperate with the corresponding limiting member 424 to clamp and fix the side of the corresponding pallet, thereby achieving double fixation of the pallet sidewall clamping and side clamping, with good fixing effect and effectively preventing the corresponding pallet from shifting during the flipping process.

The second drive assembly 4261 is configured to drive the transverse member 4260 to move closer to or further away from the first tray 11 and the second tray 21 clamped by the first clamping member 422 and the second clamping member 423.

[0052] Specifically, both the first drive assembly 420 and the third drive assembly 4262 include a dual-piston rod cylinder, wherein the two piston rods on each dual-piston rod cylinder drive in opposite directions.

[0053] By providing an auxiliary clamping assembly 426 between the first clamping member 422 and the second clamping member 423, the upper surface of the first tray 11 and the lower surface of the second tray 21 after being clamped are further fixed, thereby improving the stability during the flipping process.

[0069] By dividing the inspected pallets into Class I and Class II pallets, the handling mechanism 70 transports the Class II pallets to the fourth conveyor mechanism 60. The corresponding conveyor mechanisms then transport the Class I, Class II, and empty pallets to the sorting mechanism 80. The sorting mechanism 80 moves the defective products from the Class I pallets to empty spaces in the Class II pallets or onto empty pallets, and moves the qualified products from the Class II pallets to empty spaces in the Class I pallets. This significantly reduces the number of times the sorting mechanism 80 handles the products within the pallets, improving sorting efficiency. Alternatively, by dividing the inspected pallets into Class I pallets (with a higher percentage of qualified products) and Class II pallets (with a higher percentage of defective products), the Class I pallets are directly sent to the sorting mechanism 80 via the third conveyor mechanism 50, while the Class II pallets are transported by the handling mechanism 70 to the fourth conveyor mechanism 60 and then sent to the sorting mechanism 80 for further sorting. This achieves the classification and diversion of pallets with high and low defect rates, significantly improving overall material sorting efficiency.

The lifting assembly 64 lowers the bottom tray to a preset position. After the second drive unit 61 drives the clamping assembly 63 to move below the storage chamber, the second drive unit 61 drives the clamping assembly 63 to rise to a preset height so that the tray on the lifting assembly 64 is within the clamping range of the clamping assembly 63.
