[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] Referring to Figures 1 to 5, Figure 1 shows a perspective view of a feeding mechanism 1 provided in an embodiment of the present invention; Figure 2 shows a perspective view of a feeding mechanism 1 provided in an embodiment of the present invention; Figure 3 is an enlarged view of point A in Figure 2; Figure 4 shows a partial structural schematic diagram of a feeding mechanism 1 provided in an embodiment of the present invention; Figure 5 shows a perspective structural diagram of the longitudinal sliding table 3 and the transmission component in a feeding mechanism 1 provided in an embodiment of the present invention.

[0028] As shown in Figures 1 to 5, the technical solution provided in this application is a feeding mechanism 1, including a conveying track 2, a longitudinal sliding table 3, and an empty tray transfer assembly, wherein:

[0029] The conveyor track 2 includes a feeding channel 20 and a discharging channel 21, both extending along a first direction (shown as X direction in Figure 1) and arranged in opposite directions. Both the feeding channel 20 and the discharging channel 21 include a tray 22 and a conveying assembly. The tray 22 is used to carry the product, and the conveying assembly is used to convey the tray 22 from the feeding end to the discharging end.

[0030] The longitudinal slide 3 is located on one side of the conveying track 2 along the first direction and is correspondingly arranged with the transmission component. The longitudinal slide 3 includes a slide plate 30, and the transmission component is provided with a clearance area 232 corresponding to the slide plate 30. The longitudinal slide 3 can drive the slide plate 30 to move up and down relative to the conveying track 2 along the second direction (shown as the Z direction in Figure 1) to transfer the pallet 22 from the first station to the second station, and transfer the products in the pallet 22 by the external robot 6.

[0031] The first station includes a slide plate 30 located within a clearance zone 232, and a tray 22 located above the clearance zone 232. The second station includes a slide plate 30 carrying the tray 22 to move to the top of the longitudinal slide table 3.

[0032] The empty pallet transfer assembly is located at the top of the conveying track 2 and includes an adsorption assembly 40 and a displacement module. The adsorption assembly 40 is located above the second station and is used to adsorb the empty pallet 22 at the second station in the feeding channel 20, and to transfer the empty pallet 22 to the second station in the discharge channel 21 through the displacement module.

[0033] The feeding mechanism 1 provided in this application realizes the automatic transmission and transfer of pallets 22 and products through the conveyor rail 2, longitudinal slide 3, and empty pallet transfer assembly. It can handle feeding and discharging simultaneously, greatly reducing manual operation. The longitudinal slide 3 can quickly transfer the pallet 22 from the first station to the second station, and the external robot 6 completes the transfer of products. This rapid transfer capability makes the entire feeding process more efficient and shortens the production cycle. The empty pallet transfer assembly adsorbs and transfers the empty pallet 22 at the second station in the feeding channel 20 to the second station in the discharging channel 21, and then transmits it out of the discharging channel 21 through the longitudinal slide 3 and the transfer assembly. The external robot 6 is located on the side of the feeding channel 20 away from the discharging channel 21 along a third direction and is set close to the longitudinal slide 3. After the pallet 22 moves to the second station in the feeding channel 20, the external robot 6 adsorbs and transfers the products in the pallet 22 to the subsequent station. Furthermore, two feeding mechanisms 1 can be arranged side by side, with the feeding channels 20 of the two feeding mechanisms 1 being adjacent to each other, so that they can be jointly adsorbed and transported by the same external robotic arm, thereby reasonably improving the utilization rate of the equipment and saving costs.

[0034] In some embodiments, referring to Figures 1 to 5, both the feed channel 20 and the discharge channel 21 further include an adapter adjustment assembly, which includes a top fixing plate 240, a first side plate 241, a second side plate 242, a first adjustment plate 243, and a second adjustment plate 244. The top fixing plate 240 extends along a third direction (shown in the Y direction in Figure 1) and is disposed on top of the conveying track 2. The first side plate 241 and the second side plate 242 are arranged parallel to each other along a second direction and are disposed on top of the conveying assembly to limit the position of the tray 22. A clearance area 232 is disposed between the first side plate 241 and the second side plate 242 along a third direction. The first adjustment plate 243 and the second adjustment plate 244 are spaced apart above the top fixing plate 240 along a third direction and are respectively disposed corresponding to the first side plate 241 and the second side plate 242, with the first direction, the second direction, and the third direction being perpendicular to each other.

[0035] For example, the first side plate 241 and the second side plate 242 are arranged parallel to each other along the second direction, which can limit the position of the pallet 22 and ensure that the pallet 22 maintains a stable position during transportation. The first adjusting plate 243 and the second adjusting plate 244 can be adjusted according to pallets 22 of different sizes, allowing the feeding mechanism 1 to adapt to pallets 22 of various specifications. This adjustability avoids equipment replacement or modification due to mismatched pallet 22 sizes, greatly improving the versatility and flexibility of the equipment. The top fixing plate 240 extends along the third direction and is located on top of the conveyor track 2, serving a reinforcing and supporting function. The clearance area 232 is located between the first side plate 241 and the second side plate 242, providing sufficient space for the slide plate 30 of the longitudinal sliding table 3, avoiding collisions or interference between the side plates and the slide plate 30.

[0036] In some embodiments, referring to Figures 1 to 5, the adapter adjustment assembly further includes a connecting rod 245, an adapter block 246, and a plurality of guide posts 247. The connecting rod 245 extends along a first direction and is respectively disposed between the top fixing plate 240 and the first side plate 241 and the second side plate 242. The adapter block 246 is disposed at both ends of the top of the connecting rod 245 along the first direction and is connected to both ends of the first adjusting plate 243 and the second adjusting plate 244 along the first direction. The plurality of guide posts 247 all extend along a second direction and are spaced apart at the bottom of the connecting rod 245 along the first direction. The opposite sides of the first side plate 241 and the second side plate 242 along a third direction are connected to the plurality of guide posts 247.

[0037] For example, the connecting rod 245 connects the first adjusting plate 243 to the first side plate 241 and the second adjusting plate 244 to the second side plate 242 through the adapter block 246 and the connecting rod 245, forming a stable frame structure and enhancing the structural strength and stability of the entire adapter adjustment assembly.

[0038] In some embodiments, referring to Figures 1 to 5, the adapter adjustment assembly further includes a forward lead screw nut 248, a reverse lead screw nut 249, a commutator 250, a forward rotating rod 251, and a reverse rotating rod 252. The forward lead screw nut 248 is disposed on the top of the first adjustment plate 243, and the reverse lead screw nut 249 is disposed on the top of the second adjustment plate 244. The commutator 250 is disposed on the top of the top fixing plate 240 and is positioned between the forward lead screw nut 248 and the reverse lead screw nut 249 along a third direction. The forward rotating rod 251 extends along a third direction, and its two ends are rotatably connected to one end of the forward lead screw nut 248 and the commutator 250 along a third direction, respectively. The reverse rotating rod 252 extends along a third direction, and its two ends are rotatably connected to the other end of the reverse lead screw nut 249 and the commutator 250 along a third direction, respectively.

[0039] For example, through the rotational engagement of the forward rotating rod 251 with the forward lead screw nut 248 and the rotational engagement of the reverse rotating rod 252 with the reverse lead screw nut 249, and in conjunction with the connection of the commutator 250, the first adjusting plate 243 and the second adjusting plate 244 can achieve synchronous adjustment under the drive of the same power source.

[0040] In some embodiments, referring to Figures 1 to 5, the adapter adjustment assembly further includes an adjustment rod 253, a fixed clamp 254, and a linear guide rail 255. The fixed clamp 254 is disposed on the top of the top plate 240 and located at one end of the commutator 250 along a first direction. The adjustment rod 253 extends along the first direction, passes through the fixed clamp 254, and is rotatably connected to the commutator 250. It is used to drive the forward rod 251 and the reverse rod 252 to rotate synchronously by rotating the adjustment rod 253, so that the first adjustment plate 243 and the second adjustment plate 244 move towards or in opposite directions relative to the top plate 240 along the first direction. The linear guide rail 255 extends along a third direction and is respectively disposed between the top plate 240 and the first adjustment plate 243 and the second adjustment plate 244.

[0041] For example, the design of the adjusting lever 253 allows the operator to manually rotate the adjusting lever 253 to control the synchronous rotation of the forward lever 251 and the reverse lever 252, thereby achieving the opposite or reciprocating movement of the first adjusting plate 243 and the second adjusting plate 244, which in turn drives the first side plate 241 and the second side plate 242 to adapt to trays 22 of different sizes. The linear guide rail 255 extends along a third direction, providing precise guidance for the movement of the adjusting plate, ensuring that the adjusting plate moves smoothly along a straight line during movement and avoiding deviation caused by lateral forces or vibrations.

[0042] In some embodiments, referring to Figures 1 to 5, the displacement module includes a Y-axis fixed plate 410, a Y-axis displacement slide 411, a Z-axis fixed plate 412, a Y-axis rotating plate 413, a Z-axis displacement slide 414, and a Z-axis rotating plate 415. The Y-axis fixed plate 410 extends along a third direction and is located above the top fixed plate 240, with multiple raised posts at its bottom for connection to the top fixed plate 240. The Y-axis displacement slide 411 extends along a third direction and is located on top of the Y-axis fixed plate 410, including a first slider. The Z-axis fixed plate 412 is located on top of the first slider. The Z-axis displacement slide 414 and the Y-axis rotating plate 413 both extend along a second direction and are sequentially located along a first direction on the side of the Z-axis fixed plate 412 facing the longitudinal sliding plate 3. The Z-axis displacement slide 414 includes a second slider, and the Z-axis rotating plate 415 extends along the first direction and is connected to the second slider.

[0043] For example, through the design of the Y-axis displacement slide 411 and the Z-axis displacement slide 414, the device can achieve independent movement along the Y-axis and Z-axis. This multi-dimensional motion control allows the device to precisely adjust the position of the adsorption assembly 40 to adapt to the tray 22 at different heights and positions. Specifically, the Y-axis displacement slide 411 is provided with a cable chain 418 and a cable chain groove 416 on one side along the first direction. The drive end of the cable chain 418 is connected to the Z-axis fixing plate 412 through the cable chain sheet metal 417 to provide stable auxiliary guidance for the movement of the first slider.

[0044] In some embodiments, referring to Figures 1 to 5, the adsorption assembly 40 includes a triangular fixing frame 400, a crossbeam 401, multiple mounting plates 402, and a transition slider 403. The triangular fixing frame 400 is disposed on the side of the Z-axis rotating plate 415 facing the longitudinal sliding table 3 along a first direction. The crossbeam 401 extends along the first direction and is respectively disposed at both ends of the triangular fixing frame 400 along a third direction. Both sides of the crossbeam 401 along the third direction are provided with slots 407 extending along the first direction. Multiple mounting plates 402 are spaced apart at the bottom of the crossbeam 401 along the first direction. Each mounting plate 402 extends along a third direction and has multiple bolt connection holes 408 spaced apart at its top along the third direction. One end of the transition slider 403 is engaged with the slot 407, and the other end abuts against the top of the mounting plate 402. The transition slider 403 is provided with multiple positioning holes for fixing with the crossbeam 401 and the bolt connection holes 408.

[0045] For example, the triangular structure of the triangular fixing bracket 400 has inherent stability, effectively supporting the entire adsorption assembly 40 and ensuring its stability during movement. The design of the crossbeam 401 provides a stable support platform for the mounting plate 402 and the adapter slider 403. Multiple bolt connection holes 408 set along a third direction at the top allow the adsorption assembly 40 to be flexibly adjusted according to the specific position of the tray 22 or product. The adsorption head can be quickly installed or replaced through the bolt connection holes 408 to adapt to trays 22 of different sizes and shapes. The design of the adapter slider 403 allows the mounting plate 402 to be finely adjusted along a first direction, and precise positioning can be achieved through the cooperation of the positioning holes and the bolt connection holes 408.

[0046] In some embodiments, referring to Figures 1 to 5, the adsorption assembly 40 further includes a negative pressure suction nozzle 404, a quick connector 405, and a bending connecting piece 406. The bending connecting piece 406 is respectively disposed at both ends of the mounting plate 402, with one end corresponding to the bolt connection hole 408 and the other end bent downwards. The negative pressure suction nozzle 404 is disposed at the other end of the bending connecting piece 406 and faces the clearance area 232 along the first direction. The quick connector 405 is disposed at the top of the negative pressure suction nozzle 404 and is used to connect to the external suction device pipeline. Along the first direction, the distance between two adjacent negative pressure suction nozzles 404 is less than the distance between the first side plate 241 and the second side plate 242.

[0047] For example, the negative pressure nozzle 404, when connected to an external suction device, can quickly generate negative pressure, thereby achieving stable adsorption of the tray 22 or the product. A quick connector 405 is located on the top of the negative pressure nozzle 404, allowing for quick connection or disconnection from the suction device, improving operational flexibility and reducing downtime caused by connecting or disconnecting the suction line. Bending connecting pieces 406 are located at both ends of the mounting plate 402, one end corresponding to the bolt connection hole 408, and the other end bent downwards. This design allows the negative pressure nozzle 404 to face the clearance area 232 along the first direction, while also providing additional installation angle and position adjustment capabilities.

[0048] In some embodiments, referring to Figures 1 to 5, the transmission assembly includes a frame 230, a drive motor (not shown), a plurality of long rollers 233, and a plurality of short rollers 234. The frame 230 extends along a first direction, and connecting plates 231 are provided at both ends along a third direction. The drive motor is located on one side of the frame 230 along the third direction. The side of the frame 230 facing the longitudinal sliding table 3 along the first direction is recessed inward to form a clearance area 232 adapted to the slide plate 30. The plurality of long rollers 233 are located on one side of the clearance area 232 along the first direction and are spaced apart along the first direction. The plurality of short rollers 234 are respectively located on both sides of the clearance area 232 along the third direction and are spaced apart along the first direction. Each short roller 234 and each long roller 233 extends along the third direction, and both ends are rotatably connected to the connecting plates 231 and are synchronously driven by the drive motor to transport the pallet 22.

[0049] In some embodiments, referring to Figures 1 to 5, the feeding mechanism 1 further includes a stop detection device, which includes multiple photoelectric sensors 50 and a baffle lifting assembly 51. The multiple photoelectric sensors 50 are respectively disposed at both ends of the transmission assembly and within the clearance area 232, for detecting the position of the pallet 22. The baffle lifting assembly 51 is disposed on the same side of multiple long rollers 233, and includes a stop plate 510 and a telescopic cylinder 511. The baffle extends along the second direction, and its bottom is connected to the drive part of the telescopic cylinder 511. When the slide plate 30 carries the pallet 22 and moves, the stop plate 510 is driven by the telescopic cylinder 511 to rise above the long rollers 233 to stop the pallet 22.

[0050] For example, multiple photoelectric sensors 50 are respectively disposed at both ends of the transmission assembly and within the clearance area 232, enabling real-time detection of the position of the pallet 22. The rectangular block above the photoelectric sensor 50 indicates its detection direction. This multi-point detection method can more comprehensively monitor the positional changes of the pallet 22 during transmission, ensuring that the pallet 22 is stopped or released at the correct time and position. The baffle lifting assembly 51 drives the stop plate 510 to rise above the long roller 233 via the telescopic cylinder 511 to stop the pallet 22. This dynamic control method allows the stop plate 510 to rise rapidly when needed, preventing the pallet 22 from continuing to move forward and ensuring that the pallet 22 is stopped at the correct position. Specifically, as shown in Figures 1 and 5, in the feeding channel 20, the baffle lifting assembly 51 is located on the side of the multiple long rollers 233 near the avoidance area 232, so that when the slide plate 30 rises, the front pallet 22 stops moving; in the discharging channel 21, the baffle lifting assembly 51 is located on the side of the multiple long rollers 233 away from the avoidance area 232, so that the empty pallet 22 can be discharged in an orderly manner at intervals.
