[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 8 , the embodiment of the present invention includes:

[0028] A tray feeding device comprises: a roller line 2, a material cutting mechanism 3, a transfer mechanism 4, a tray elevator 5, and a recovery belt mechanism 6 arranged on a frame 1, the roller line 2 conveys a tray filled with materials to the material cutting mechanism 3, the material cutting mechanism 3 separates the trays one by one and places them on the transfer mechanism 4, the transfer mechanism 4 places the tray filled with materials to the material picking position of the tray elevator 5 to wait for material picking, and after picking up the materials, the tray elevator 5 places the empty tray to the recovery belt mechanism 6 to collect the empty tray.

[0029] A guide rail 8 and a support column are set on the partition 7 of the frame 1, and the transfer mechanism 4 can slide on the slide rail 365. The cutting mechanism 3 is fixedly connected to the partition 7 through the support column and spans over the guide rail 8. The front and rear ends of the guide rail 8 are respectively provided with a gear mechanism 35 for limiting the transfer mechanism 4 to prevent the transfer mechanism 4 from moving beyond the range of the guide rail 8.

[0030] The cutting mechanism 3 comprises a tray separation mechanism 31 for isolating a single tray, a suction cup mechanism 32 for separating a single tray from other trays, and a first sensor 33 .

[0031] The suction cup mechanism 32 includes a lifting platform 36 disposed on a suction cup mechanism frame and moving in a vertical direction, a suction cup assembly 37 disposed on the lifting platform 36 and moving in a vertical direction, and a second sensor 38 .

[0032] The tray separation mechanism 31 includes an upper support plate 311 and a lower support plate 312 that are arranged on the tray separation mechanism frame and move in the horizontal direction. The upper support plate 311 is located above the lower support plate 312. When the roller line 2 transports multiple stacked trays filled with materials to the cutting mechanism 3, the first sensor 33 detects the distance between the notch positions of the trays to determine whether the placement direction of the trays is correct. The cylinder drives the lower support plate 312 to extend forward in the horizontal direction to support the bottom tray. The cylinder drives the upper support plate 311 to extend forward in the horizontal direction to support the second to last tray at the bottom. The lifting platform 36 rises, and the suction cup assembly 37 sucks the bottom tray tightly. The support plate 313 is connected to the upper support plate 311 through the lifting claw 314. The cylinder drives the support plate 313 to rise, thereby driving the lifting claw 314 to rise, giving an upward force to the second to last tray at the bottom, so as to facilitate the separation of the bottom tray from the second to last tray at the bottom.

[0033] The lifting platform 36 includes an upper supporting plate 361 and a lifting frame 362. The upper supporting plate 361 is arranged on the lifting frame 362. The lifting frame 362 includes two groups of two support rods 363 connected in an X shape. The intersection of the two support rods 363 is connected by a rotating shaft so that the support rods 363 can rotate. One end of the two support rods 363 is respectively connected to the upper supporting plate 361 through a rotating shaft. A fixed block 364 and a slide rail 365 are arranged on the bottom plate of the lifting platform 36. The other end of one of the support rods 363 is connected to the fixed block 364 through a rotating shaft, and the other end of the other one is connected to the slider on the slide rail 365 through a rotating shaft. The cylinder is fixedly connected to the slider through a connecting rod. The cylinder drives the slider to move in the horizontal direction along the slide rail 365. The slider drives the support rod 363 to move so that the upper supporting plate 361 rises and falls.

[0034] The suction cup assembly 37 is connected to the upper supporting plate 361 through a connecting plate, and the cylinder drives the suction cup assembly 37 to move in the vertical direction.

[0035] The second sensor 38 detects the height of the lowest pallet, the cylinder drives the upper support plate 361 to rise, and the cylinder drives the suction cup assembly 37 to rise to the height of the lowest pallet detected, the suction cup assembly 37 sucks the lowest pallet tightly, the cylinder drives the lifting claw to rise, giving an upward force to the second to last pallet at the bottom, the cylinder drives the upper support plate 361 to descend, to separate the pallets, and the cylinder controls the suction cup assembly 37 to descend to place the lowest pallet on the transfer mechanism 4.

[0036] The transfer mechanism 4 includes a clamping device 41 arranged on the transfer pallet, a pallet supporting device 42 for lifting the pallet, and a third sensor 43. Furthermore, a storage hole 44 is arranged on the transfer pallet, and the clamping devices 41 are respectively arranged around the storage holes 44, and at least on three sides to ensure that the pallet is firmly clamped. The pallet supporting devices 42 are respectively arranged around the storage holes 44 and are relatively arranged to ensure the stability of lifting the pallet; the third sensor 43 detects whether the pallet is in place, and the cylinder drives the pallet supporting device 42 to move forward in the horizontal direction to lift the pallet that has been separated from the tray. The cylinder drives the clamping device 41 to move forward in the horizontal direction to clamp the pallet. The transfer mechanism moves along the guide rail 8 to send the bottom pallet filled with materials to the material picking position of the pallet elevator 5 to wait for material picking, and the transfer mechanism 4 returns to continue the handling work.

[0037] After the suction cup mechanism 32 has transported the bottom tray full of materials, it rises, the suction cup assembly 37 lifts the penultimate tray full of materials, the lower support plate 312 of the tray separating mechanism 31 retracts, and the suction cup mechanism 32 moves the penultimate tray full of materials to the position of the bottom tray. At this time, the penultimate tray full of materials becomes the bottom tray full of materials, and the tray separating mechanism 31 separates the trays, and so on.

[0038] The pallet elevator 5 includes a pallet partition 51 that moves in the vertical direction, and the width of the pallet partition 51 is smaller than the width between the belts of the recovery belt mechanism 6. The motor drives the pallet partition 51 to move in the vertical direction. Preferably, gaps are set between the belts of the recovery belt mechanism 6. After taking the material, the pallet partition 51 holds the empty pallet down, and the pallet elevator 5 places the empty pallet on the belt 61 of the recovery belt mechanism 6 where the empty pallet is placed. The fourth sensor 62 detects the empty pallet, and the recovery belt mechanism 6 starts to drive the empty pallet forward. When the fifth sensor 63 detects the empty pallet, the recovery belt mechanism 6 pauses to remind the collection of materials.

[0039] The beneficial effects of the tray-dividing and feeding equipment of the present invention are: providing a tray-dividing and feeding equipment, which can separate multiple stacked trays full of materials from bottom to top one by one through a cutting mechanism, so as to facilitate material taking, and then output and collect the empty trays after taking the materials, so that a large amount of materials can be input at one time, and materials can be taken in batches, thereby improving work efficiency, and has the advantages of safety, reliability, full automation, precise positioning, compact structure, etc., and at the same time has broad market prospects in the application and popularization of loading and unloading of laser welding machines.
